It is represented as a single file on +your disk and represents a consistent snapshot of your data. + +To open your database, simply use the `bolt.Open()` function: + +```go +package main + +import ( + "log" + + bolt "github.com/coreos/bbolt" +) + +func main() { + // Open the my.db data file in your current directory. + // It will be created if it doesn't exist. + db, err := bolt.Open("my.db", 0600, nil) + if err != nil { + log.Fatal(err) + } + defer db.Close() + + ... +} +``` + +Please note that Bolt obtains a file lock on the data file so multiple processes +cannot open the same database at the same time. Opening an already open Bolt +database will cause it to hang until the other process closes it. To prevent +an indefinite wait you can pass a timeout option to the `Open()` function: + +```go +db, err := bolt.Open("my.db", 0600, &bolt.Options{Timeout: 1 * time.Second}) +``` + + +### Transactions + +Bolt allows only one read-write transaction at a time but allows as many +read-only transactions as you want at a time. Each transaction has a consistent +view of the data as it existed when the transaction started. + +Individual transactions and all objects created from them (e.g. buckets, keys) +are not thread safe. To work with data in multiple goroutines you must start +a transaction for each one or use locking to ensure only one goroutine accesses +a transaction at a time. Creating transaction from the `DB` is thread safe. + +Read-only transactions and read-write transactions should not depend on one +another and generally shouldn't be opened simultaneously in the same goroutine. +This can cause a deadlock as the read-write transaction needs to periodically +re-map the data file but it cannot do so while a read-only transaction is open. + + +#### Read-write transactions + +To start a read-write transaction, you can use the `DB.Update()` function: + +```go +err := db.Update(func(tx *bolt.Tx) error { + ... + return nil +}) +``` + +Inside the closure, you have a consistent view of the database. You commit the +transaction by returning `nil` at the end. You can also rollback the transaction +at any point by returning an error. All database operations are allowed inside +a read-write transaction. + +Always check the return error as it will report any disk failures that can cause +your transaction to not complete. If you return an error within your closure +it will be passed through. + + +#### Read-only transactions + +To start a read-only transaction, you can use the `DB.View()` function: + +```go +err := db.View(func(tx *bolt.Tx) error { + ... + return nil +}) +``` + +You also get a consistent view of the database within this closure, however, +no mutating operations are allowed within a read-only transaction. You can only +retrieve buckets, retrieve values, and copy the database within a read-only +transaction. + + +#### Batch read-write transactions + +Each `DB.Update()` waits for disk to commit the writes. This overhead +can be minimized by combining multiple updates with the `DB.Batch()` +function: + +```go +err := db.Batch(func(tx *bolt.Tx) error { + ... + return nil +}) +``` + +Concurrent Batch calls are opportunistically combined into larger +transactions. Batch is only useful when there are multiple goroutines +calling it. + +The trade-off is that `Batch` can call the given +function multiple times, if parts of the transaction fail. The +function must be idempotent and side effects must take effect only +after a successful return from `DB.Batch()`. + +For example: don't display messages from inside the function, instead +set variables in the enclosing scope: + +```go +var id uint64 +err := db.Batch(func(tx *bolt.Tx) error { + // Find last key in bucket, decode as bigendian uint64, increment + // by one, encode back to []byte, and add new key. + ... + id = newValue + return nil +}) +if err != nil { + return ... +} +fmt.Println("Allocated ID %d", id) +``` + + +#### Managing transactions manually + +The `DB.View()` and `DB.Update()` functions are wrappers around the `DB.Begin()` +function. These helper functions will start the transaction, execute a function, +and then safely close your transaction if an error is returned. This is the +recommended way to use Bolt transactions. + +However, sometimes you may want to manually start and end your transactions. +You can use the `DB.Begin()` function directly but **please** be sure to close +the transaction. + +```go +// Start a writable transaction. +tx, err := db.Begin(true) +if err != nil { + return err +} +defer tx.Rollback() + +// Use the transaction... +_, err := tx.CreateBucket([]byte("MyBucket")) +if err != nil { + return err +} + +// Commit the transaction and check for error. +if err := tx.Commit(); err != nil { + return err +} +``` + +The first argument to `DB.Begin()` is a boolean stating if the transaction +should be writable. + + +### Using buckets + +Buckets are collections of key/value pairs within the database. All keys in a +bucket must be unique. You can create a bucket using the `DB.CreateBucket()` +function: + +```go +db.Update(func(tx *bolt.Tx) error { + b, err := tx.CreateBucket([]byte("MyBucket")) + if err != nil { + return fmt.Errorf("create bucket: %s", err) + } + return nil +}) +``` + +You can also create a bucket only if it doesn't exist by using the +`Tx.CreateBucketIfNotExists()` function. It's a common pattern to call this +function for all your top-level buckets after you open your database so you can +guarantee that they exist for future transactions. + +To delete a bucket, simply call the `Tx.DeleteBucket()` function. + + +### Using key/value pairs + +To save a key/value pair to a bucket, use the `Bucket.Put()` function: + +```go +db.Update(func(tx *bolt.Tx) error { + b := tx.Bucket([]byte("MyBucket")) + err := b.Put([]byte("answer"), []byte("42")) + return err +}) +``` + +This will set the value of the `"answer"` key to `"42"` in the `MyBucket` +bucket. To retrieve this value, we can use the `Bucket.Get()` function: + +```go +db.View(func(tx *bolt.Tx) error { + b := tx.Bucket([]byte("MyBucket")) + v := b.Get([]byte("answer")) + fmt.Printf("The answer is: %s\n", v) + return nil +}) +``` + +The `Get()` function does not return an error because its operation is +guaranteed to work (unless there is some kind of system failure). If the key +exists then it will return its byte slice value. If it doesn't exist then it +will return `nil`. It's important to note that you can have a zero-length value +set to a key which is different than the key not existing. + +Use the `Bucket.Delete()` function to delete a key from the bucket. + +Please note that values returned from `Get()` are only valid while the +transaction is open. If you need to use a value outside of the transaction +then you must use `copy()` to copy it to another byte slice. + + +### Autoincrementing integer for the bucket +By using the `NextSequence()` function, you can let Bolt determine a sequence +which can be used as the unique identifier for your key/value pairs. See the +example below. + +```go +// CreateUser saves u to the store. The new user ID is set on u once the data is persisted. +func (s *Store) CreateUser(u *User) error { + return s.db.Update(func(tx *bolt.Tx) error { + // Retrieve the users bucket. + // This should be created when the DB is first opened. + b := tx.Bucket([]byte("users")) + + // Generate ID for the user. + // This returns an error only if the Tx is closed or not writeable. + // That can't happen in an Update() call so I ignore the error check. + id, _ := b.NextSequence() + u.ID = int(id) + + // Marshal user data into bytes. + buf, err := json.Marshal(u) + if err != nil { + return err + } + + // Persist bytes to users bucket. + return b.Put(itob(u.ID), buf) + }) +} + +// itob returns an 8-byte big endian representation of v. +func itob(v int) []byte { + b := make([]byte, 8) + binary.BigEndian.PutUint64(b, uint64(v)) + return b +} + +type User struct { + ID int + ... +} +``` + +### Iterating over keys + +Bolt stores its keys in byte-sorted order within a bucket. This makes sequential +iteration over these keys extremely fast. To iterate over keys we'll use a +`Cursor`: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume bucket exists and has keys + b := tx.Bucket([]byte("MyBucket")) + + c := b.Cursor() + + for k, v := c.First(); k != nil; k, v = c.Next() { + fmt.Printf("key=%s, value=%s\n", k, v) + } + + return nil +}) +``` + +The cursor allows you to move to a specific point in the list of keys and move +forward or backward through the keys one at a time. + +The following functions are available on the cursor: + +``` +First() Move to the first key. +Last() Move to the last key. +Seek() Move to a specific key. +Next() Move to the next key. +Prev() Move to the previous key. +``` + +Each of those functions has a return signature of `(key []byte, value []byte)`. +When you have iterated to the end of the cursor then `Next()` will return a +`nil` key. You must seek to a position using `First()`, `Last()`, or `Seek()` +before calling `Next()` or `Prev()`. If you do not seek to a position then +these functions will return a `nil` key. + +During iteration, if the key is non-`nil` but the value is `nil`, that means +the key refers to a bucket rather than a value. Use `Bucket.Bucket()` to +access the sub-bucket. + + +#### Prefix scans + +To iterate over a key prefix, you can combine `Seek()` and `bytes.HasPrefix()`: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume bucket exists and has keys + c := tx.Bucket([]byte("MyBucket")).Cursor() + + prefix := []byte("1234") + for k, v := c.Seek(prefix); k != nil && bytes.HasPrefix(k, prefix); k, v = c.Next() { + fmt.Printf("key=%s, value=%s\n", k, v) + } + + return nil +}) +``` + +#### Range scans + +Another common use case is scanning over a range such as a time range. If you +use a sortable time encoding such as RFC3339 then you can query a specific +date range like this: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume our events bucket exists and has RFC3339 encoded time keys. + c := tx.Bucket([]byte("Events")).Cursor() + + // Our time range spans the 90's decade. + min := []byte("1990-01-01T00:00:00Z") + max := []byte("2000-01-01T00:00:00Z") + + // Iterate over the 90's. + for k, v := c.Seek(min); k != nil && bytes.Compare(k, max) <= 0; k, v = c.Next() { + fmt.Printf("%s: %s\n", k, v) + } + + return nil +}) +``` + +Note that, while RFC3339 is sortable, the Golang implementation of RFC3339Nano does not use a fixed number of digits after the decimal point and is therefore not sortable. + + +#### ForEach() + +You can also use the function `ForEach()` if you know you'll be iterating over +all the keys in a bucket: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume bucket exists and has keys + b := tx.Bucket([]byte("MyBucket")) + + b.ForEach(func(k, v []byte) error { + fmt.Printf("key=%s, value=%s\n", k, v) + return nil + }) + return nil +}) +``` + +Please note that keys and values in `ForEach()` are only valid while +the transaction is open. If you need to use a key or value outside of +the transaction, you must use `copy()` to copy it to another byte +slice. + +### Nested buckets + +You can also store a bucket in a key to create nested buckets. The API is the +same as the bucket management API on the `DB` object: + +```go +func (*Bucket) CreateBucket(key []byte) (*Bucket, error) +func (*Bucket) CreateBucketIfNotExists(key []byte) (*Bucket, error) +func (*Bucket) DeleteBucket(key []byte) error +``` + +Say you had a multi-tenant application where the root level bucket was the account bucket. Inside of this bucket was a sequence of accounts which themselves are buckets. And inside the sequence bucket you could have many buckets pertaining to the Account itself (Users, Notes, etc) isolating the information into logical groupings. + +```go + +// createUser creates a new user in the given account. +func createUser(accountID int, u *User) error { + // Start the transaction. + tx, err := db.Begin(true) + if err != nil { + return err + } + defer tx.Rollback() + + // Retrieve the root bucket for the account. + // Assume this has already been created when the account was set up. + root := tx.Bucket([]byte(strconv.FormatUint(accountID, 10))) + + // Setup the users bucket. + bkt, err := root.CreateBucketIfNotExists([]byte("USERS")) + if err != nil { + return err + } + + // Generate an ID for the new user. + userID, err := bkt.NextSequence() + if err != nil { + return err + } + u.ID = userID + + // Marshal and save the encoded user. + if buf, err := json.Marshal(u); err != nil { + return err + } else if err := bkt.Put([]byte(strconv.FormatUint(u.ID, 10)), buf); err != nil { + return err + } + + // Commit the transaction. + if err := tx.Commit(); err != nil { + return err + } + + return nil +} + +``` + + + + +### Database backups + +Bolt is a single file so it's easy to backup. You can use the `Tx.WriteTo()` +function to write a consistent view of the database to a writer. If you call +this from a read-only transaction, it will perform a hot backup and not block +your other database reads and writes. + +By default, it will use a regular file handle which will utilize the operating +system's page cache. See the [`Tx`](https://godoc.org/github.com/coreos/bbolt#Tx) +documentation for information about optimizing for larger-than-RAM datasets. + +One common use case is to backup over HTTP so you can use tools like `cURL` to +do database backups: + +```go +func BackupHandleFunc(w http.ResponseWriter, req *http.Request) { + err := db.View(func(tx *bolt.Tx) error { + w.Header().Set("Content-Type", "application/octet-stream") + w.Header().Set("Content-Disposition", `attachment; filename="my.db"`) + w.Header().Set("Content-Length", strconv.Itoa(int(tx.Size()))) + _, err := tx.WriteTo(w) + return err + }) + if err != nil { + http.Error(w, err.Error(), http.StatusInternalServerError) + } +} +``` + +Then you can backup using this command: + +```sh +$ curl http://localhost/backup > my.db +``` + +Or you can open your browser to `http://localhost/backup` and it will download +automatically. + +If you want to backup to another file you can use the `Tx.CopyFile()` helper +function. + + +### Statistics + +The database keeps a running count of many of the internal operations it +performs so you can better understand what's going on. By grabbing a snapshot +of these stats at two points in time we can see what operations were performed +in that time range. + +For example, we could start a goroutine to log stats every 10 seconds: + +```go +go func() { + // Grab the initial stats. + prev := db.Stats() + + for { + // Wait for 10s. + time.Sleep(10 * time.Second) + + // Grab the current stats and diff them. + stats := db.Stats() + diff := stats.Sub(&prev) + + // Encode stats to JSON and print to STDERR. + json.NewEncoder(os.Stderr).Encode(diff) + + // Save stats for the next loop. + prev = stats + } +}() +``` + +It's also useful to pipe these stats to a service such as statsd for monitoring +or to provide an HTTP endpoint that will perform a fixed-length sample. + + +### Read-Only Mode + +Sometimes it is useful to create a shared, read-only Bolt database. To this, +set the `Options.ReadOnly` flag when opening your database. Read-only mode +uses a shared lock to allow multiple processes to read from the database but +it will block any processes from opening the database in read-write mode. + +```go +db, err := bolt.Open("my.db", 0666, &bolt.Options{ReadOnly: true}) +if err != nil { + log.Fatal(err) +} +``` + +### Mobile Use (iOS/Android) + +Bolt is able to run on mobile devices by leveraging the binding feature of the +[gomobile](https://github.com/golang/mobile) tool. Create a struct that will +contain your database logic and a reference to a `*bolt.DB` with a initializing +constructor that takes in a filepath where the database file will be stored. +Neither Android nor iOS require extra permissions or cleanup from using this method. + +```go +func NewBoltDB(filepath string) *BoltDB { + db, err := bolt.Open(filepath+"/demo.db", 0600, nil) + if err != nil { + log.Fatal(err) + } + + return &BoltDB{db} +} + +type BoltDB struct { + db *bolt.DB + ... +} + +func (b *BoltDB) Path() string { + return b.db.Path() +} + +func (b *BoltDB) Close() { + b.db.Close() +} +``` + +Database logic should be defined as methods on this wrapper struct. + +To initialize this struct from the native language (both platforms now sync +their local storage to the cloud. These snippets disable that functionality for the +database file): + +#### Android + +```java +String path; +if (android.os.Build.VERSION.SDK_INT >=android.os.Build.VERSION_CODES.LOLLIPOP){ + path = getNoBackupFilesDir().getAbsolutePath(); +} else{ + path = getFilesDir().getAbsolutePath(); +} +Boltmobiledemo.BoltDB boltDB = Boltmobiledemo.NewBoltDB(path) +``` + +#### iOS + +```objc +- (void)demo { + NSString* path = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, + NSUserDomainMask, + YES) objectAtIndex:0]; + GoBoltmobiledemoBoltDB * demo = GoBoltmobiledemoNewBoltDB(path); + [self addSkipBackupAttributeToItemAtPath:demo.path]; + //Some DB Logic would go here + [demo close]; +} + +- (BOOL)addSkipBackupAttributeToItemAtPath:(NSString *) filePathString +{ + NSURL* URL= [NSURL fileURLWithPath: filePathString]; + assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]); + + NSError *error = nil; + BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES] + forKey: NSURLIsExcludedFromBackupKey error: &error]; + if(!success){ + NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error); + } + return success; +} + +``` + +## Resources + +For more information on getting started with Bolt, check out the following articles: + +* [Intro to BoltDB: Painless Performant Persistence](http://npf.io/2014/07/intro-to-boltdb-painless-performant-persistence/) by [Nate Finch](https://github.com/natefinch). +* [Bolt -- an embedded key/value database for Go](https://www.progville.com/go/bolt-embedded-db-golang/) by Progville + + +## Comparison with other databases + +### Postgres, MySQL, & other relational databases + +Relational databases structure data into rows and are only accessible through +the use of SQL. This approach provides flexibility in how you store and query +your data but also incurs overhead in parsing and planning SQL statements. Bolt +accesses all data by a byte slice key. This makes Bolt fast to read and write +data by key but provides no built-in support for joining values together. + +Most relational databases (with the exception of SQLite) are standalone servers +that run separately from your application. This gives your systems +flexibility to connect multiple application servers to a single database +server but also adds overhead in serializing and transporting data over the +network. Bolt runs as a library included in your application so all data access +has to go through your application's process. This brings data closer to your +application but limits multi-process access to the data. + + +### LevelDB, RocksDB + +LevelDB and its derivatives (RocksDB, HyperLevelDB) are similar to Bolt in that +they are libraries bundled into the application, however, their underlying +structure is a log-structured merge-tree (LSM tree). An LSM tree optimizes +random writes by using a write ahead log and multi-tiered, sorted files called +SSTables. Bolt uses a B+tree internally and only a single file. Both approaches +have trade-offs. + +If you require a high random write throughput (>10,000 w/sec) or you need to use +spinning disks then LevelDB could be a good choice. If your application is +read-heavy or does a lot of range scans then Bolt could be a good choice. + +One other important consideration is that LevelDB does not have transactions. +It supports batch writing of key/values pairs and it supports read snapshots +but it will not give you the ability to do a compare-and-swap operation safely. +Bolt supports fully serializable ACID transactions. + + +### LMDB + +Bolt was originally a port of LMDB so it is architecturally similar. Both use +a B+tree, have ACID semantics with fully serializable transactions, and support +lock-free MVCC using a single writer and multiple readers. + +The two projects have somewhat diverged. LMDB heavily focuses on raw performance +while Bolt has focused on simplicity and ease of use. For example, LMDB allows +several unsafe actions such as direct writes for the sake of performance. Bolt +opts to disallow actions which can leave the database in a corrupted state. The +only exception to this in Bolt is `DB.NoSync`. + +There are also a few differences in API. LMDB requires a maximum mmap size when +opening an `mdb_env` whereas Bolt will handle incremental mmap resizing +automatically. LMDB overloads the getter and setter functions with multiple +flags whereas Bolt splits these specialized cases into their own functions. + + +## Caveats & Limitations + +It's important to pick the right tool for the job and Bolt is no exception. +Here are a few things to note when evaluating and using Bolt: + +* Bolt is good for read intensive workloads. Sequential write performance is + also fast but random writes can be slow. You can use `DB.Batch()` or add a + write-ahead log to help mitigate this issue. + +* Bolt uses a B+tree internally so there can be a lot of random page access. + SSDs provide a significant performance boost over spinning disks. + +* Try to avoid long running read transactions. Bolt uses copy-on-write so + old pages cannot be reclaimed while an old transaction is using them. + +* Byte slices returned from Bolt are only valid during a transaction. Once the + transaction has been committed or rolled back then the memory they point to + can be reused by a new page or can be unmapped from virtual memory and you'll + see an `unexpected fault address` panic when accessing it. + +* Bolt uses an exclusive write lock on the database file so it cannot be + shared by multiple processes. + +* Be careful when using `Bucket.FillPercent`. Setting a high fill percent for + buckets that have random inserts will cause your database to have very poor + page utilization. + +* Use larger buckets in general. Smaller buckets causes poor page utilization + once they become larger than the page size (typically 4KB). + +* Bulk loading a lot of random writes into a new bucket can be slow as the + page will not split until the transaction is committed. Randomly inserting + more than 100,000 key/value pairs into a single new bucket in a single + transaction is not advised. + +* Bolt uses a memory-mapped file so the underlying operating system handles the + caching of the data. Typically, the OS will cache as much of the file as it + can in memory and will release memory as needed to other processes. This means + that Bolt can show very high memory usage when working with large databases. + However, this is expected and the OS will release memory as needed. Bolt can + handle databases much larger than the available physical RAM, provided its + memory-map fits in the process virtual address space. It may be problematic + on 32-bits systems. + +* The data structures in the Bolt database are memory mapped so the data file + will be endian specific. This means that you cannot copy a Bolt file from a + little endian machine to a big endian machine and have it work. For most + users this is not a concern since most modern CPUs are little endian. + +* Because of the way pages are laid out on disk, Bolt cannot truncate data files + and return free pages back to the disk. Instead, Bolt maintains a free list + of unused pages within its data file. These free pages can be reused by later + transactions. This works well for many use cases as databases generally tend + to grow. However, it's important to note that deleting large chunks of data + will not allow you to reclaim that space on disk. + + For more information on page allocation, [see this comment][page-allocation]. + +[page-allocation]: https://github.com/boltdb/bolt/issues/308#issuecomment-74811638 + + +## Reading the Source + +Bolt is a relatively small code base (<5KLOC) for an embedded, serializable, +transactional key/value database so it can be a good starting point for people +interested in how databases work. + +The best places to start are the main entry points into Bolt: + +- `Open()` - Initializes the reference to the database. It's responsible for + creating the database if it doesn't exist, obtaining an exclusive lock on the + file, reading the meta pages, & memory-mapping the file. + +- `DB.Begin()` - Starts a read-only or read-write transaction depending on the + value of the `writable` argument. This requires briefly obtaining the "meta" + lock to keep track of open transactions. Only one read-write transaction can + exist at a time so the "rwlock" is acquired during the life of a read-write + transaction. + +- `Bucket.Put()` - Writes a key/value pair into a bucket. After validating the + arguments, a cursor is used to traverse the B+tree to the page and position + where they key & value will be written. Once the position is found, the bucket + materializes the underlying page and the page's parent pages into memory as + "nodes". These nodes are where mutations occur during read-write transactions. + These changes get flushed to disk during commit. + +- `Bucket.Get()` - Retrieves a key/value pair from a bucket. This uses a cursor + to move to the page & position of a key/value pair. During a read-only + transaction, the key and value data is returned as a direct reference to the + underlying mmap file so there's no allocation overhead. For read-write + transactions, this data may reference the mmap file or one of the in-memory + node values. + +- `Cursor` - This object is simply for traversing the B+tree of on-disk pages + or in-memory nodes. It can seek to a specific key, move to the first or last + value, or it can move forward or backward. The cursor handles the movement up + and down the B+tree transparently to the end user. + +- `Tx.Commit()` - Converts the in-memory dirty nodes and the list of free pages + into pages to be written to disk. Writing to disk then occurs in two phases. + First, the dirty pages are written to disk and an `fsync()` occurs. Second, a + new meta page with an incremented transaction ID is written and another + `fsync()` occurs. This two phase write ensures that partially written data + pages are ignored in the event of a crash since the meta page pointing to them + is never written. Partially written meta pages are invalidated because they + are written with a checksum. + +If you have additional notes that could be helpful for others, please submit +them via pull request. + + +## Other Projects Using Bolt + +Below is a list of public, open source projects that use Bolt: + +* [BoltDbWeb](https://github.com/evnix/boltdbweb) - A web based GUI for BoltDB files. +* [Operation Go: A Routine Mission](http://gocode.io) - An online programming game for Golang using Bolt for user accounts and a leaderboard. +* [Bazil](https://bazil.org/) - A file system that lets your data reside where it is most convenient for it to reside. +* [DVID](https://github.com/janelia-flyem/dvid) - Added Bolt as optional storage engine and testing it against Basho-tuned leveldb. +* [Skybox Analytics](https://github.com/skybox/skybox) - A standalone funnel analysis tool for web analytics. +* [Scuttlebutt](https://github.com/benbjohnson/scuttlebutt) - Uses Bolt to store and process all Twitter mentions of GitHub projects. +* [Wiki](https://github.com/peterhellberg/wiki) - A tiny wiki using Goji, BoltDB and Blackfriday. +* [ChainStore](https://github.com/pressly/chainstore) - Simple key-value interface to a variety of storage engines organized as a chain of operations. +* [MetricBase](https://github.com/msiebuhr/MetricBase) - Single-binary version of Graphite. +* [Gitchain](https://github.com/gitchain/gitchain) - Decentralized, peer-to-peer Git repositories aka "Git meets Bitcoin". +* [event-shuttle](https://github.com/sclasen/event-shuttle) - A Unix system service to collect and reliably deliver messages to Kafka. +* [ipxed](https://github.com/kelseyhightower/ipxed) - Web interface and api for ipxed. +* [BoltStore](https://github.com/yosssi/boltstore) - Session store using Bolt. +* [photosite/session](https://godoc.org/bitbucket.org/kardianos/photosite/session) - Sessions for a photo viewing site. +* [LedisDB](https://github.com/siddontang/ledisdb) - A high performance NoSQL, using Bolt as optional storage. +* [ipLocator](https://github.com/AndreasBriese/ipLocator) - A fast ip-geo-location-server using bolt with bloom filters. +* [cayley](https://github.com/google/cayley) - Cayley is an open-source graph database using Bolt as optional backend. +* [bleve](http://www.blevesearch.com/) - A pure Go search engine similar to ElasticSearch that uses Bolt as the default storage backend. +* [tentacool](https://github.com/optiflows/tentacool) - REST api server to manage system stuff (IP, DNS, Gateway...) on a linux server. +* [Seaweed File System](https://github.com/chrislusf/seaweedfs) - Highly scalable distributed key~file system with O(1) disk read. +* [InfluxDB](https://influxdata.com) - Scalable datastore for metrics, events, and real-time analytics. +* [Freehold](http://tshannon.bitbucket.org/freehold/) - An open, secure, and lightweight platform for your files and data. +* [Prometheus Annotation Server](https://github.com/oliver006/prom_annotation_server) - Annotation server for PromDash & Prometheus service monitoring system. +* [Consul](https://github.com/hashicorp/consul) - Consul is service discovery and configuration made easy.

It supports +fully serializable transactions, ACID semantics, and lock-free MVCC with +multiple readers and a single writer. Bolt can be used for projects that +want a simple data store without the need to add large dependencies such as +Postgres or MySQL. + +Bolt is a single-level, zero-copy, B+tree data store. This means that Bolt is +optimized for fast read access and does not require recovery in the event of a +system crash. Transactions which have not finished committing will simply be +rolled back in the event of a crash. + +The design of Bolt is based on Howard Chu's LMDB database project. + +Bolt currently works on Windows, Mac OS X, and Linux. + + +Basics + +There are only a few types in Bolt: DB, Bucket, Tx, and Cursor. The DB is +a collection of buckets and is represented by a single file on disk. A bucket is +a collection of unique keys that are associated with values. + +Transactions provide either read-only or read-write access to the database. +Read-only transactions can retrieve key/value pairs and can use Cursors to +iterate over the dataset sequentially. Read-write transactions can create and +delete buckets and can insert and remove keys. Only one read-write transaction +is allowed at a time. + + +Caveats + +The database uses a read-only, memory-mapped data file to ensure that +applications cannot corrupt the database, however, this means that keys and +values returned from Bolt cannot be changed. Writing to a read-only byte slice +will cause Go to panic. + +Keys and values retrieved from the database are only valid for the life of +the transaction. When used outside the transaction, these byte slices can +point to different data or can point to invalid memory which will cause a panic. + + +*/ +package bolt diff --git a/vendor/github.com/coreos/bbolt/errors.go b/vendor/github.com/coreos/bbolt/errors.go new file mode 100644 index 0000000..a3620a3 --- /dev/null +++ b/vendor/github.com/coreos/bbolt/errors.go @@ -0,0 +1,71 @@ +package bolt + +import "errors" + +// These errors can be returned when opening or calling methods on a DB. +var ( + // ErrDatabaseNotOpen is returned when a DB instance is accessed before it + // is opened or after it is closed. + ErrDatabaseNotOpen = errors.New("database not open") + + // ErrDatabaseOpen is returned when opening a database that is + // already open. + ErrDatabaseOpen = errors.New("database already open") + + // ErrInvalid is returned when both meta pages on a database are invalid. + // This typically occurs when a file is not a bolt database. + ErrInvalid = errors.New("invalid database") + + // ErrVersionMismatch is returned when the data file was created with a + // different version of Bolt. + ErrVersionMismatch = errors.New("version mismatch") + + // ErrChecksum is returned when either meta page checksum does not match. + ErrChecksum = errors.New("checksum error") + + // ErrTimeout is returned when a database cannot obtain an exclusive lock + // on the data file after the timeout passed to Open(). + ErrTimeout = errors.New("timeout") +) + +// These errors can occur when beginning or committing a Tx. +var ( + // ErrTxNotWritable is returned when performing a write operation on a + // read-only transaction. + ErrTxNotWritable = errors.New("tx not writable") + + // ErrTxClosed is returned when committing or rolling back a transaction + // that has already been committed or rolled back. + ErrTxClosed = errors.New("tx closed") + + // ErrDatabaseReadOnly is returned when a mutating transaction is started on a + // read-only database. + ErrDatabaseReadOnly = errors.New("database is in read-only mode") +) + +// These errors can occur when putting or deleting a value or a bucket. +var ( + // ErrBucketNotFound is returned when trying to access a bucket that has + // not been created yet. + ErrBucketNotFound = errors.New("bucket not found") + + // ErrBucketExists is returned when creating a bucket that already exists. + ErrBucketExists = errors.New("bucket already exists") + + // ErrBucketNameRequired is returned when creating a bucket with a blank name. + ErrBucketNameRequired = errors.New("bucket name required") + + // ErrKeyRequired is returned when inserting a zero-length key. + ErrKeyRequired = errors.New("key required") + + // ErrKeyTooLarge is returned when inserting a key that is larger than MaxKeySize. + ErrKeyTooLarge = errors.New("key too large") + + // ErrValueTooLarge is returned when inserting a value that is larger than MaxValueSize. + ErrValueTooLarge = errors.New("value too large") + + // ErrIncompatibleValue is returned when trying create or delete a bucket + // on an existing non-bucket key or when trying to create or delete a + // non-bucket key on an existing bucket key. + ErrIncompatibleValue = errors.New("incompatible value") +) diff --git a/vendor/github.com/coreos/bbolt/freelist.go b/vendor/github.com/coreos/bbolt/freelist.go new file mode 100644 index 0000000..266f154 --- /dev/null +++ b/vendor/github.com/coreos/bbolt/freelist.go @@ -0,0 +1,333 @@ +package bolt + +import ( + "fmt" + "sort" + "unsafe" +) + +// txPending holds a list of pgids and corresponding allocation txns +// that are pending to be freed. +type txPending struct { + ids []pgid + alloctx []txid // txids allocating the ids + lastReleaseBegin txid // beginning txid of last matching releaseRange +} + +// freelist represents a list of all pages that are available for allocation. +// It also tracks pages that have been freed but are still in use by open transactions. +type freelist struct { + ids []pgid // all free and available free page ids. + allocs map[pgid]txid // mapping of txid that allocated a pgid. + pending map[txid]*txPending // mapping of soon-to-be free page ids by tx. + cache map[pgid]bool // fast lookup of all free and pending page ids. +} + +// newFreelist returns an empty, initialized freelist. +func newFreelist() *freelist { + return &freelist{ + allocs: make(map[pgid]txid), + pending: make(map[txid]*txPending), + cache: make(map[pgid]bool), + } +} + +// size returns the size of the page after serialization. +func (f *freelist) size() int { + n := f.count() + if n >= 0xFFFF { + // The first element will be used to store the count.

HTTP charset

+ + +
+ + +
 
+ + + + + +
+

The character encoding of a page can be set using the HTTP header charset declaration.

+

The test contains a div with a class name that contains the following sequence of bytes: 0xC3 0xBD 0xC3 0xA4 0xC3 0xA8. These represent different sequences of characters in ISO 8859-15, ISO 8859-1 and UTF-8. The external, UTF-8-encoded stylesheet contains a selector .test div.ÜÀÚ. This matches the sequence of bytes above when they are interpreted as ISO 8859-15. If the class name matches the selector then the test will pass.

The only character encoding declaration for this HTML file is in the HTTP header, which sets the encoding to ISO 8859-15.

HTTP vs UTF-8 BOM

+ + +
+ + +
 
+ + + + + +
+

A character encoding set in the HTTP header has lower precedence than the UTF-8 signature.

+

The HTTP header attempts to set the character encoding to ISO 8859-15. The page starts with a UTF-8 signature.

The test contains a div with a class name that contains the following sequence of bytes: 0xC3 0xBD 0xC3 0xA4 0xC3 0xA8. These represent different sequences of characters in ISO 8859-15, ISO 8859-1 and UTF-8. The external, UTF-8-encoded stylesheet contains a selector .test div.ýäè. This matches the sequence of bytes above when they are interpreted as UTF-8. If the class name matches the selector then the test will pass.

If the test is unsuccessful, the characters  should appear at the top of the page. These represent the bytes that make up the UTF-8 signature when encountered in the ISO 8859-15 encoding.

    Compile packages and dependencies
    
+
    
+Usage:
+
    
+
    go build [-o output] [-i] [build flags] [packages]
+
    
+
    
+Build compiles the packages named by the import paths,
+along with their dependencies, but it does not install the results.
+
    
+
    
+If the arguments to build are a list of .go files, build treats
+them as a list of source files specifying a single package.
+
    
+
    
+When compiling a single main package, build writes
+the resulting executable to an output file named after
+the first source file ('go build ed.go rx.go' writes 'ed' or 'ed.exe')
+or the source code directory ('go build unix/sam' writes 'sam' or 'sam.exe').
+The '.exe' suffix is added when writing a Windows executable.
+
    
+
    
+When compiling multiple packages or a single non-main package,
+build compiles the packages but discards the resulting object,
+serving only as a check that the packages can be built.
+
    
+
    
+When compiling packages, build ignores files that end in '_test.go'.
+
    
+
    
+The -o flag, only allowed when compiling a single package,
+forces build to write the resulting executable or object
+to the named output file, instead of the default behavior described
+in the last two paragraphs.
+
    
+
    
+The -i flag installs the packages that are dependencies of the target.
+
    
+
    
+The build flags are shared by the build, clean, get, install, list, run,
+and test commands:
+
    
+
    -a
+	force rebuilding of packages that are already up-to-date.
+-n
+	print the commands but do not run them.
+-p n
+	the number of programs, such as build commands or
+	test binaries, that can be run in parallel.
+	The default is the number of CPUs available.
+-race
+	enable data race detection.
+	Supported only on linux/amd64, freebsd/amd64, darwin/amd64 and windows/amd64.
+-msan
+	enable interoperation with memory sanitizer.
+	Supported only on linux/amd64,
+	and only with Clang/LLVM as the host C compiler.
+-v
+	print the names of packages as they are compiled.
+-work
+	print the name of the temporary work directory and
+	do not delete it when exiting.
+-x
+	print the commands.
+
+-asmflags 'flag list'
+	arguments to pass on each go tool asm invocation.
+-buildmode mode
+	build mode to use. See 'go help buildmode' for more.
+-compiler name
+	name of compiler to use, as in runtime.Compiler (gccgo or gc).
+-gccgoflags 'arg list'
+	arguments to pass on each gccgo compiler/linker invocation.
+-gcflags 'arg list'
+	arguments to pass on each go tool compile invocation.
+-installsuffix suffix
+	a suffix to use in the name of the package installation directory,
+	in order to keep output separate from default builds.
+	If using the -race flag, the install suffix is automatically set to race
+	or, if set explicitly, has _race appended to it.  Likewise for the -msan
+	flag.  Using a -buildmode option that requires non-default compile flags
+	has a similar effect.
+-ldflags 'flag list'
+	arguments to pass on each go tool link invocation.
+-linkshared
+	link against shared libraries previously created with
+	-buildmode=shared.
+-pkgdir dir
+	install and load all packages from dir instead of the usual locations.
+	For example, when building with a non-standard configuration,
+	use -pkgdir to keep generated packages in a separate location.
+-tags 'tag list'
+	a list of build tags to consider satisfied during the build.
+	For more information about build tags, see the description of
+	build constraints in the documentation for the go/build package.
+-toolexec 'cmd args'
+	a program to use to invoke toolchain programs like vet and asm.
+	For example, instead of running asm, the go command will run
+	'cmd args /path/to/asm <arguments for asm>'.
+
    
+
    
+The list flags accept a space-separated list of strings. To embed spaces
+in an element in the list, surround it with either single or double quotes.
+
    
+
    
+For more about specifying packages, see 'go help packages'.
+For more about where packages and binaries are installed,
+run 'go help gopath'.
+For more about calling between Go and C/C++, run 'go help c'.
+
    
+
    
+Note: Build adheres to certain conventions such as those described
+by 'go help gopath'. Not all projects can follow these conventions,
+however. Installations that have their own conventions or that use
+a separate software build system may choose to use lower-level
+invocations such as 'go tool compile' and 'go tool link' to avoid
+some of the overheads and design decisions of the build tool.

+
    Remove object files
    
+
    
+Usage:
+
    
+
    go clean [-i] [-r] [-n] [-x] [build flags] [packages]
+
    
+
    
+Clean removes object files from package source directories.
+The go command builds most objects in a temporary directory,
+so go clean is mainly concerned with object files left by other
+tools or by manual invocations of go build.
+
    
+
    
+Specifically, clean removes the following files from each of the
+source directories corresponding to the import paths:
+
    
+
    _obj/            old object directory, left from Makefiles
+_test/           old test directory, left from Makefiles
+_testmain.go     old gotest file, left from Makefiles
+test.out         old test log, left from Makefiles
+build.out        old test log, left from Makefiles
+*.[568ao]        object files, left from Makefiles
+
+DIR(.exe)        from go build
+DIR.test(.exe)   from go test -c
+MAINFILE(.exe)   from go build MAINFILE.go
+*.so             from SWIG
+
    
+
    
+In the list, DIR represents the final path element of the
+directory, and MAINFILE is the base name of any Go source
+file in the directory that is not included when building
+the package.
+
    
+
    
+The -i flag causes clean to remove the corresponding installed
+archive or binary (what 'go install' would create).
+
    
+
    
+The -n flag causes clean to print the remove commands it would execute,
+but not run them.
+
    
+
    
+The -r flag causes clean to be applied recursively to all the
+dependencies of the packages named by the import paths.
+
    
+
    
+The -x flag causes clean to print remove commands as it executes them.
+
    
+
    
+For more about build flags, see 'go help build'.
+
    
+
    
+For more about specifying packages, see 'go help packages'.
+
    
+
    Show documentation for package or symbol
    
+
    
+Usage:
+
    
+
    go doc [-u] [-c] [package|[package.]symbol[.method]]
+
    
+
    
+Doc prints the documentation comments associated with the item identified by its
+arguments (a package, const, func, type, var, or method) followed by a one-line
+summary of each of the first-level items "under" that item (package-level
+declarations for a package, methods for a type, etc.).
+
    
+
    
+Doc accepts zero, one, or two arguments.
+
    
+
    
+Given no arguments, that is, when run as
+
    
+
    go doc
+
    
+
    
+it prints the package documentation for the package in the current directory.
+If the package is a command (package main), the exported symbols of the package
+are elided from the presentation unless the -cmd flag is provided.
+
    
+
    
+When run with one argument, the argument is treated as a Go-syntax-like
+representation of the item to be documented. What the argument selects depends
+on what is installed in GOROOT and GOPATH, as well as the form of the argument,
+which is schematically one of these:
+
    
+
    go doc <pkg>
+go doc <sym>[.<method>]
+go doc [<pkg>.]<sym>[.<method>]
+go doc [<pkg>.][<sym>.]<method>
+
    
+
    
+The first item in this list matched by the argument is the one whose documentation
+is printed. (See the examples below.) However, if the argument starts with a capital
+letter it is assumed to identify a symbol or method in the current directory.
+
    
+
    
+For packages, the order of scanning is determined lexically in breadth-first order.
+That is, the package presented is the one that matches the search and is nearest
+the root and lexically first at its level of the hierarchy.  The GOROOT tree is
+always scanned in its entirety before GOPATH.
+
    
+
    
+If there is no package specified or matched, the package in the current
+directory is selected, so "go doc Foo" shows the documentation for symbol Foo in
+the current package.
+
    
+
    
+The package path must be either a qualified path or a proper suffix of a
+path. The go tool's usual package mechanism does not apply: package path
+elements like . and ... are not implemented by go doc.
+
    
+
    
+When run with two arguments, the first must be a full package path (not just a
+suffix), and the second is a symbol or symbol and method; this is similar to the
+syntax accepted by godoc:
+
    
+
    go doc <pkg> <sym>[.<method>]
+
    
+
    
+In all forms, when matching symbols, lower-case letters in the argument match
+either case but upper-case letters match exactly. This means that there may be
+multiple matches of a lower-case argument in a package if different symbols have
+different cases. If this occurs, documentation for all matches is printed.
+
    
+
    
+Examples:
+
    
+
    go doc
+	Show documentation for current package.
+go doc Foo
+	Show documentation for Foo in the current package.
+	(Foo starts with a capital letter so it cannot match
+	a package path.)
+go doc encoding/json
+	Show documentation for the encoding/json package.
+go doc json
+	Shorthand for encoding/json.
+go doc json.Number (or go doc json.number)
+	Show documentation and method summary for json.Number.
+go doc json.Number.Int64 (or go doc json.number.int64)
+	Show documentation for json.Number's Int64 method.
+go doc cmd/doc
+	Show package docs for the doc command.
+go doc -cmd cmd/doc
+	Show package docs and exported symbols within the doc command.
+go doc template.new
+	Show documentation for html/template's New function.
+	(html/template is lexically before text/template)
+go doc text/template.new # One argument
+	Show documentation for text/template's New function.
+go doc text/template new # Two arguments
+	Show documentation for text/template's New function.
+
+At least in the current tree, these invocations all print the
+documentation for json.Decoder's Decode method:
+
+go doc json.Decoder.Decode
+go doc json.decoder.decode
+go doc json.decode
+cd go/src/encoding/json; go doc decode
+
    
+
    
+Flags:
+
    
+
    -c
+	Respect case when matching symbols.
+-cmd
+	Treat a command (package main) like a regular package.
+	Otherwise package main's exported symbols are hidden
+	when showing the package's top-level documentation.
+-u
+	Show documentation for unexported as well as exported
+	symbols and methods.
+
    
+
    Print Go environment information
    
+
    
+Usage:
+
    
+
    go env [var ...]
+
    
+
    
+Env prints Go environment information.
+
    
+
    
+By default env prints information as a shell script
+(on Windows, a batch file).  If one or more variable
+names is given as arguments,  env prints the value of
+each named variable on its own line.
+
    
+
    Start a bug report
    
+
    
+Usage:
+
    
+
    go bug
+
    
+
    
+Bug opens the default browser and starts a new bug report.
+The report includes useful system information.
+
    
+
    Run go tool fix on packages
    
+
    
+Usage:
+
    
+
    go fix [packages]
+
    
+
    
+Fix runs the Go fix command on the packages named by the import paths.
+
    
+
    
+For more about fix, see 'go doc cmd/fix'.
+For more about specifying packages, see 'go help packages'.
+
    
+
    
+To run fix with specific options, run 'go tool fix'.
+
    
+
    
+See also: go fmt, go vet.
+
    
+
    Run gofmt on package sources
    
+
    
+Usage:
+
    
+
    go fmt [-n] [-x] [packages]
+
    
+
    
+Fmt runs the command 'gofmt -l -w' on the packages named
+by the import paths.  It prints the names of the files that are modified.
+
    
+
    
+For more about gofmt, see 'go doc cmd/gofmt'.
+For more about specifying packages, see 'go help packages'.
+
    
+
    
+The -n flag prints commands that would be executed.
+The -x flag prints commands as they are executed.
+
    
+
    
+To run gofmt with specific options, run gofmt itself.
+
    
+
    
+See also: go fix, go vet.
+
    
+
    Generate Go files by processing source
    
+
    
+Usage:
+
    
+
    go generate [-run regexp] [-n] [-v] [-x] [build flags] [file.go... | packages]
+
    
+
    
+Generate runs commands described by directives within existing
+files. Those commands can run any process but the intent is to
+create or update Go source files.
+
    
+
    
+Go generate is never run automatically by go build, go get, go test,
+and so on. It must be run explicitly.
+
    
+
    
+Go generate scans the file for directives, which are lines of
+the form,
+
    
+
    //go:generate command argument...
+
    
+
    
+(note: no leading spaces and no space in "//go") where command
+is the generator to be run, corresponding to an executable file
+that can be run locally. It must either be in the shell path
+(gofmt), a fully qualified path (/usr/you/bin/mytool), or a
+command alias, described below.
+
    
+
    
+Note that go generate does not parse the file, so lines that look
+like directives in comments or multiline strings will be treated
+as directives.
+
    
+
    
+The arguments to the directive are space-separated tokens or
+double-quoted strings passed to the generator as individual
+arguments when it is run.
+
    
+
    
+Quoted strings use Go syntax and are evaluated before execution; a
+quoted string appears as a single argument to the generator.
+
    
+
    
+Go generate sets several variables when it runs the generator:
+
    
+
    $GOARCH
+	The execution architecture (arm, amd64, etc.)
+$GOOS
+	The execution operating system (linux, windows, etc.)
+$GOFILE
+	The base name of the file.
+$GOLINE
+	The line number of the directive in the source file.
+$GOPACKAGE
+	The name of the package of the file containing the directive.
+$DOLLAR
+	A dollar sign.
+
    
+
    
+Other than variable substitution and quoted-string evaluation, no
+special processing such as "globbing" is performed on the command
+line.
+
    
+
    
+As a last step before running the command, any invocations of any
+environment variables with alphanumeric names, such as $GOFILE or
+$HOME, are expanded throughout the command line. The syntax for
+variable expansion is $NAME on all operating systems.  Due to the
+order of evaluation, variables are expanded even inside quoted
+strings. If the variable NAME is not set, $NAME expands to the
+empty string.
+
    
+
    
+A directive of the form,
+
    
+
    //go:generate -command xxx args...
+
    
+
    
+specifies, for the remainder of this source file only, that the
+string xxx represents the command identified by the arguments. This
+can be used to create aliases or to handle multiword generators.
+For example,
+
    
+
    //go:generate -command foo go tool foo
+
    
+
    
+specifies that the command "foo" represents the generator
+"go tool foo".
+
    
+
    
+Generate processes packages in the order given on the command line,
+one at a time. If the command line lists .go files, they are treated
+as a single package. Within a package, generate processes the
+source files in a package in file name order, one at a time. Within
+a source file, generate runs generators in the order they appear
+in the file, one at a time.
+
    
+
    
+If any generator returns an error exit status, "go generate" skips
+all further processing for that package.
+
    
+
    
+The generator is run in the package's source directory.
+
    
+
    
+Go generate accepts one specific flag:
+
    
+
    -run=""
+	if non-empty, specifies a regular expression to select
+	directives whose full original source text (excluding
+	any trailing spaces and final newline) matches the
+	expression.
+
    
+
    
+It also accepts the standard build flags including -v, -n, and -x.
+The -v flag prints the names of packages and files as they are
+processed.
+The -n flag prints commands that would be executed.
+The -x flag prints commands as they are executed.
+
    
+
    
+For more about build flags, see 'go help build'.
+
    
+
    
+For more about specifying packages, see 'go help packages'.
+
    
+
    Download and install packages and dependencies
    
+
    
+Usage:
+
    
+
    go get [-d] [-f] [-fix] [-insecure] [-t] [-u] [build flags] [packages]
+
    
+
    
+Get downloads the packages named by the import paths, along with their
+dependencies. It then installs the named packages, like 'go install'.
+
    
+
    
+The -d flag instructs get to stop after downloading the packages; that is,
+it instructs get not to install the packages.
+
    
+
    
+The -f flag, valid only when -u is set, forces get -u not to verify that
+each package has been checked out from the source control repository
+implied by its import path. This can be useful if the source is a local fork
+of the original.
+
    
+
    
+The -fix flag instructs get to run the fix tool on the downloaded packages
+before resolving dependencies or building the code.
+
    
+
    
+The -insecure flag permits fetching from repositories and resolving
+custom domains using insecure schemes such as HTTP. Use with caution.
+
    
+
    
+The -t flag instructs get to also download the packages required to build
+the tests for the specified packages.
+
    
+
    
+The -u flag instructs get to use the network to update the named packages
+and their dependencies.  By default, get uses the network to check out
+missing packages but does not use it to look for updates to existing packages.
+
    
+
    
+The -v flag enables verbose progress and debug output.
+
    
+
    
+Get also accepts build flags to control the installation. See 'go help build'.
+
    
+
    
+When checking out a new package, get creates the target directory
+GOPATH/src/<import-path>. If the GOPATH contains multiple entries,
+get uses the first one. For more details see: 'go help gopath'.
+
    
+
    
+When checking out or updating a package, get looks for a branch or tag
+that matches the locally installed version of Go. The most important
+rule is that if the local installation is running version "go1", get
+searches for a branch or tag named "go1". If no such version exists it
+retrieves the most recent version of the package.
+
    
+
    
+When go get checks out or updates a Git repository,
+it also updates any git submodules referenced by the repository.
+
    
+
    
+Get never checks out or updates code stored in vendor directories.
+

    Compile and install packages and dependencies
    
+
    
+Usage:
+
    
+
    go install [build flags] [packages]
+
    
+
    
+Install compiles and installs the packages named by the import paths,
+along with their dependencies.
+
    
+
    
+For more about the build flags, see 'go help build'.
+For more about specifying packages, see 'go help packages'.
+

+
    
+
    List packages
    
+
    
+Usage:
+
    
+
    go list [-e] [-f format] [-json] [build flags] [packages]
+
    
+
    
+List lists the packages named by the import paths, one per line.
+
    
+
    
+The default output shows the package import path:
+
    
+
    bytes
+encoding/json
+github.com/gorilla/mux
+golang.org/x/net/html
+
    
+
    
+The -f flag specifies an alternate format for the list, using the
+syntax of package template.  The default output is equivalent to -f
+''. The struct being passed to the template is:
+
    
+

+    Error      *PackageError   // error loading package
+    DepsErrors []*PackageError // errors loading dependencies
+}
+
    
+
    
+Packages stored in vendor directories report an ImportPath that includes the
+path to the vendor directory (for example, "d/vendor/p" instead of "p"),
+so that the ImportPath uniquely identifies a given copy of a package.
+The Imports, Deps, TestImports, and XTestImports lists also contain these
+expanded imports paths. See golang.org/s/go15vendor for more about vendoring.
+
    
+
    
+The error information, if any, is
+
    
+
    type PackageError struct {
+    ImportStack   []string // shortest path from package named on command line to this one
+    Pos           string   // position of error (if present, file:line:col)
+    Err           string   // the error itself
+}
+
    
+
    
+The template function "join" calls strings.Join.
+
    
+
    
+The template function "context" returns the build context, defined as:
+
    
+
    type Context struct {
+	GOARCH        string   // target architecture
+	GOOS          string   // target operating system
+	GOROOT        string   // Go root
+	GOPATH        string   // Go path
+	CgoEnabled    bool     // whether cgo can be used
+	UseAllFiles   bool     // use files regardless of +build lines, file names
+	Compiler      string   // compiler to assume when computing target paths
+	BuildTags     []string // build constraints to match in +build lines
+	ReleaseTags   []string // releases the current release is compatible with
+	InstallSuffix string   // suffix to use in the name of the install dir
+}
+
    
+
    
+For more information about the meaning of these fields see the documentation
+for the go/build package's Context type.
+
    
+
    
+The -json flag causes the package data to be printed in JSON format
+instead of using the template format.
+
    
+
    
+The -e flag changes the handling of erroneous packages, those that
+cannot be found or are malformed.  By default, the list command
+prints an error to standard error for each erroneous package and
+omits the packages from consideration during the usual printing.
+With the -e flag, the list command never prints errors to standard
+error and instead processes the erroneous packages with the usual
+printing.  Erroneous packages will have a non-empty ImportPath and
+a non-nil Error field; other information may or may not be missing
+(zeroed).

    Compile and run Go program
    
+
    
+Usage:
+
    
+
    go run [build flags] [-exec xprog] gofiles... [arguments...]
+
    
+
    
+Run compiles and runs the main package comprising the named Go source files.
+A Go source file is defined to be a file ending in a literal ".go" suffix.
+
    
+
    
+By default, 'go run' runs the compiled binary directly: 'a.out arguments...'.
+If the -exec flag is given, 'go run' invokes the binary using xprog:
+
    
+
    'xprog a.out arguments...'.
+
    
+
    
+If the -exec flag is not given, GOOS or GOARCH is different from the system
+default, and a program named go_$GOOS_$GOARCH_exec can be found
+on the current search path, 'go run' invokes the binary using that program,
+for example 'go_nacl_386_exec a.out arguments...'. This allows execution of
+cross-compiled programs when a simulator or other execution method is
+available.
+
    
+
    
+For more about build flags, see 'go help build'.
+
    
+
    
+See also: go build.
+
    
+
    Test packages
    
+
    
+Usage:
+
    
+
    go test [build/test flags] [packages] [build/test flags & test binary flags]
+
    
+
    
+'Go test' automates testing the packages named by the import paths.
+It prints a summary of the test results in the format:
+
    
+
    ok   archive/tar   0.011s
+FAIL archive/zip   0.022s
+ok   compress/gzip 0.033s
+...
+
    
+
    
+followed by detailed output for each failed package.
+
    
+
    
+'Go test' recompiles each package along with any files with names matching
+the file pattern "*_test.go".
+Files whose names begin with "_" (including "_test.go") or "." are ignored.
+These additional files can contain test functions, benchmark functions, and
+example functions.  See 'go help testfunc' for more.
+Each listed package causes the execution of a separate test binary.
+
    
+
    
+Test files that declare a package with the suffix "_test" will be compiled as a
+separate package, and then linked and run with the main test binary.
+
    
+
    
+The go tool will ignore a directory named "testdata", making it available
+to hold ancillary data needed by the tests.
+
    
+
    
+By default, go test needs no arguments.  It compiles and tests the package
+with source in the current directory, including tests, and runs the tests.
+
    
+
    
+The package is built in a temporary directory so it does not interfere with the
+non-test installation.
+
    
+
    
+In addition to the build flags, the flags handled by 'go test' itself are:
+
    
+
    -args
+    Pass the remainder of the command line (everything after -args)
+    to the test binary, uninterpreted and unchanged.
+    Because this flag consumes the remainder of the command line,
+    the package list (if present) must appear before this flag.
+
+-c
+    Compile the test binary to pkg.test but do not run it
+    (where pkg is the last element of the package's import path).
+    The file name can be changed with the -o flag.
+
+-exec xprog
+    Run the test binary using xprog. The behavior is the same as
+    in 'go run'. See 'go help run' for details.
+
+-i
+    Install packages that are dependencies of the test.
+    Do not run the test.
+
+-o file
+    Compile the test binary to the named file.
+    The test still runs (unless -c or -i is specified).
+
    
+
    
+The test binary also accepts flags that control execution of the test; these
+flags are also accessible by 'go test'. See 'go help testflag' for details.
+

+
    Run specified go tool
    
+
    
+Usage:
+
    
+
    go tool [-n] command [args...]
+
    
+
    
+Tool runs the go tool command identified by the arguments.
+With no arguments it prints the list of known tools.
+
    
+
    
+The -n flag causes tool to print the command that would be
+executed but not execute it.
+
    
+
    
+For more about each tool command, see 'go tool command -h'.
+
    
+
    Print Go version
    
+
    
+Usage:
+
    
+
    go version
+
    
+
    
+Version prints the Go version, as reported by runtime.Version.
+
    
+
    Run go tool vet on packages
    
+
    
+Usage:
+
    
+
    go vet [-n] [-x] [build flags] [packages]
+
    
+
    
+Vet runs the Go vet command on the packages named by the import paths.
+
    
+
    
+For more about vet, see 'go doc cmd/vet'.
+For more about specifying packages, see 'go help packages'.
+
    
+
    
+To run the vet tool with specific options, run 'go tool vet'.
+
    
+
    
+The -n flag prints commands that would be executed.
+The -x flag prints commands as they are executed.
+

+
    Calling between Go and C
    
+
    
+There are two different ways to call between Go and C/C++ code.
+
    
+
    
+The first is the cgo tool, which is part of the Go distribution.  For
+information on how to use it see the cgo documentation (go doc cmd/cgo).
+
    
+
    
+The second is the SWIG program, which is a general tool for
+interfacing between languages.  For information on SWIG see
+http://swig.org/.  When running go build, any file with a .swig
+extension will be passed to SWIG.  Any file with a .swigcxx extension
+will be passed to SWIG with the -c++ option.
+
    
+
    
+When either cgo or SWIG is used, go build will pass any .c, .m, .s,
+or .S files to the C compiler, and any .cc, .cpp, .cxx files to the C++
+compiler.  The CC or CXX environment variables may be set to determine
+the C or C++ compiler, respectively, to use.
+
    
+
    Description of build modes
    
+
    
+The 'go build' and 'go install' commands take a -buildmode argument which
+indicates which kind of object file is to be built. Currently supported values
+are:
+
    
+
    -buildmode=archive
+	Build the listed non-main packages into .a files. Packages named
+	main are ignored.
+
+-buildmode=c-archive
+	Build the listed main package, plus all packages it imports,
+	into a C archive file. The only callable symbols will be those
+	functions exported using a cgo //export comment. Requires
+	exactly one main package to be listed.
+
+-buildmode=c-shared
+	Build the listed main packages, plus all packages that they
+	import, into C shared libraries. The only callable symbols will
+	be those functions exported using a cgo //export comment.
+	Non-main packages are ignored.
+
+-buildmode=default
+	Listed main packages are built into executables and listed
+	non-main packages are built into .a files (the default
+	behavior).
+
+-buildmode=shared
+	Combine all the listed non-main packages into a single shared
+	library that will be used when building with the -linkshared
+	option. Packages named main are ignored.
+
+-buildmode=exe
+	Build the listed main packages and everything they import into
+	executables. Packages not named main are ignored.
+
+-buildmode=pie
+	Build the listed main packages and everything they import into
+	position independent executables (PIE). Packages not named
+	main are ignored.
+
+-buildmode=plugin
+	Build the listed main packages, plus all packages that they
+	import, into a Go plugin. Packages not named main are ignored.
+
    
+
    File types
    
+
    
+The go command examines the contents of a restricted set of files
+in each directory. It identifies which files to examine based on
+the extension of the file name. These extensions are:
+
    
+
    .go
+	Go source files.
+.c, .h
+	C source files.
+	If the package uses cgo or SWIG, these will be compiled with the
+	OS-native compiler (typically gcc); otherwise they will
+	trigger an error.
+.cc, .cpp, .cxx, .hh, .hpp, .hxx
+	C++ source files. Only useful with cgo or SWIG, and always
+	compiled with the OS-native compiler.
+.m
+	Objective-C source files. Only useful with cgo, and always
+	compiled with the OS-native compiler.
+.s, .S
+	Assembler source files.
+	If the package uses cgo or SWIG, these will be assembled with the
+	OS-native assembler (typically gcc (sic)); otherwise they
+	will be assembled with the Go assembler.
+.swig, .swigcxx
+	SWIG definition files.
+.syso
+	System object files.
+
    
+
    
+Files of each of these types except .syso may contain build
+constraints, but the go command stops scanning for build constraints
+at the first item in the file that is not a blank line or //-style
+line comment. See the go/build package documentation for
+more details.
+
    
+
    
+Non-test Go source files can also include a //go:binary-only-package
+comment, indicating that the package sources are included
+for documentation only and must not be used to build the
+package binary. This enables distribution of Go packages in
+their compiled form alone. See the go/build package documentation
+for more details.
+
    
+
    GOPATH environment variable
    
+
    
+The Go path is used to resolve import statements.
+It is implemented by and documented in the go/build package.
+
    
+
    
+The GOPATH environment variable lists places to look for Go code.
+On Unix, the value is a colon-separated string.
+On Windows, the value is a semicolon-separated string.
+On Plan 9, the value is a list.
+
    
+
    
+If the environment variable is unset, GOPATH defaults
+to a subdirectory named "go" in the user's home directory
+($HOME/go on Unix, %USERPROFILE%\go on Windows),
+unless that directory holds a Go distribution.
+Run "go env GOPATH" to see the current GOPATH.
+
    
+
    
+See https://golang.org/wiki/SettingGOPATH to set a custom GOPATH.
+
    
+
    
+Each directory listed in GOPATH must have a prescribed structure:
+
    
+
    
+The src directory holds source code.  The path below src
+determines the import path or executable name.
+
    
+
    
+The pkg directory holds installed package objects.
+As in the Go tree, each target operating system and
+architecture pair has its own subdirectory of pkg
+(pkg/GOOS_GOARCH).
+
    
+
    
+If DIR is a directory listed in the GOPATH, a package with
+source in DIR/src/foo/bar can be imported as "foo/bar" and
+has its compiled form installed to "DIR/pkg/GOOS_GOARCH/foo/bar.a".
+
    
+
    
+The bin directory holds compiled commands.
+Each command is named for its source directory, but only
+the final element, not the entire path.  That is, the
+command with source in DIR/src/foo/quux is installed into
+DIR/bin/quux, not DIR/bin/foo/quux.  The "foo/" prefix is stripped
+so that you can add DIR/bin to your PATH to get at the
+installed commands.  If the GOBIN environment variable is
+set, commands are installed to the directory it names instead
+of DIR/bin. GOBIN must be an absolute path.
+
    
+
    
+Here's an example directory layout:
+
    
+
    GOPATH=/home/user/go
+
+/home/user/go/
+    src/
+        foo/
+            bar/               (go code in package bar)
+                x.go
+            quux/              (go code in package main)
+                y.go
+    bin/
+        quux                   (installed command)
+    pkg/
+        linux_amd64/
+            foo/
+                bar.a          (installed package object)
+
    
+
    
+Go searches each directory listed in GOPATH to find source code,
+but new packages are always downloaded into the first directory
+in the list.
+
    
+
    
+See https://golang.org/doc/code.html for an example.
+
    
+
    Internal Directories
    
+
    
+Code in or below a directory named "internal" is importable only
+by code in the directory tree rooted at the parent of "internal".
+Here's an extended version of the directory layout above:
+
    
+
    /home/user/go/
+    src/
+        crash/
+            bang/              (go code in package bang)
+                b.go
+        foo/                   (go code in package foo)
+            f.go
+            bar/               (go code in package bar)
+                x.go
+            internal/
+                baz/           (go code in package baz)
+                    z.go
+            quux/              (go code in package main)
+                y.go
+
    
+
    
+The code in z.go is imported as "foo/internal/baz", but that
+import statement can only appear in source files in the subtree
+rooted at foo. The source files foo/f.go, foo/bar/x.go, and
+foo/quux/y.go can all import "foo/internal/baz", but the source file
+crash/bang/b.go cannot.
+
    
+
    
+See https://golang.org/s/go14internal for details.
+
    
+
    Vendor Directories
    
+
    
+Go 1.6 includes support for using local copies of external dependencies
+to satisfy imports of those dependencies, often referred to as vendoring.
+
    
+
    
+Code below a directory named "vendor" is importable only
+by code in the directory tree rooted at the parent of "vendor",
+and only using an import path that omits the prefix up to and
+including the vendor element.
+
    
+
    
+Here's the example from the previous section,
+but with the "internal" directory renamed to "vendor"
+and a new foo/vendor/crash/bang directory added:
+
    
+
    /home/user/go/
+    src/
+        crash/
+            bang/              (go code in package bang)
+                b.go
+        foo/                   (go code in package foo)
+            f.go
+            bar/               (go code in package bar)
+                x.go
+            vendor/
+                crash/
+                    bang/      (go code in package bang)
+                        b.go
+                baz/           (go code in package baz)
+                    z.go
+            quux/              (go code in package main)
+                y.go
+
    
+
    
+The same visibility rules apply as for internal, but the code
+in z.go is imported as "baz", not as "foo/vendor/baz".
+
    
+
    
+Code in vendor directories deeper in the source tree shadows
+code in higher directories. Within the subtree rooted at foo, an import
+of "crash/bang" resolves to "foo/vendor/crash/bang", not the
+top-level "crash/bang".
+
    
+
    
+Code in vendor directories is not subject to import path
+checking (see 'go help importpath').
+
    
+
    
+When 'go get' checks out or updates a git repository, it now also
+updates submodules.
+
    
+
    
+Vendor directories do not affect the placement of new repositories
+being checked out for the first time by 'go get': those are always
+placed in the main GOPATH, never in a vendor subtree.
+
    
+
    
+See https://golang.org/s/go15vendor for details.
+
    
+
    Environment variables
    
+
    
+The go command, and the tools it invokes, examine a few different
+environment variables. For many of these, you can see the default
+value of on your system by running 'go env NAME', where NAME is the
+name of the variable.
+
    
+
    
+General-purpose environment variables:
+
    
+
    GCCGO
+	The gccgo command to run for 'go build -compiler=gccgo'.
+GOARCH
+	The architecture, or processor, for which to compile code.
+	Examples are amd64, 386, arm, ppc64.
+GOBIN
+	The directory where 'go install' will install a command.
+GOOS
+	The operating system for which to compile code.
+	Examples are linux, darwin, windows, netbsd.
+GOPATH
+	For more details see: 'go help gopath'.
+GORACE
+	Options for the race detector.
+	See https://golang.org/doc/articles/race_detector.html.
+GOROOT
+	The root of the go tree.
+
    
+
    
+Environment variables for use with cgo:
+
    
+
    CC
+	The command to use to compile C code.
+CGO_ENABLED
+	Whether the cgo command is supported.  Either 0 or 1.
+CGO_CFLAGS
+	Flags that cgo will pass to the compiler when compiling
+	C code.
+CGO_CPPFLAGS
+	Flags that cgo will pass to the compiler when compiling
+	C or C++ code.

+
    Import path syntax
    
+
    
+An import path (see 'go help packages') denotes a package stored in the local
+file system.  In general, an import path denotes either a standard package (such
+as "unicode/utf8") or a package found in one of the work spaces (For more
+details see: 'go help gopath').
+
    
+
    Relative import paths
    
+
    
+An import path beginning with ./ or ../ is called a relative path.
+The toolchain supports relative import paths as a shortcut in two ways.
+
    
+
    
+First, a relative path can be used as a shorthand on the command line.
+If you are working in the directory containing the code imported as
+"unicode" and want to run the tests for "unicode/utf8", you can type
+"go test ./utf8" instead of needing to specify the full path.
+Similarly, in the reverse situation, "go test .." will test "unicode" from
+the "unicode/utf8" directory. Relative patterns are also allowed, like
+"go test ./..." to test all subdirectories. See 'go help packages' for details
+on the pattern syntax.
+
    
+
    
+Second, if you are compiling a Go program not in a work space,
+you can use a relative path in an import statement in that program
+to refer to nearby code also not in a work space.
+This makes it easy to experiment with small multipackage programs
+outside of the usual work spaces, but such programs cannot be
+installed with "go install" (there is no work space in which to install them),
+so they are rebuilt from scratch each time they are built.
+To avoid ambiguity, Go programs cannot use relative import paths
+within a work space.
+
    
+
    Remote import paths
    
+
    
+Certain import paths also
+describe how to obtain the source code for the package using
+a revision control system.
+
    
+
    
+A few common code hosting sites have special syntax:
+
    
+
    Bitbucket (Git, Mercurial)
+
+	import "bitbucket.org/user/project"
+	import "bitbucket.org/user/project/sub/directory"
+
+GitHub (Git)
+
+	import "github.com/user/project"
+	import "github.com/user/project/sub/directory"
+
+Launchpad (Bazaar)
+
+	import "launchpad.net/project"
+	import "launchpad.net/project/series"
+	import "launchpad.net/project/series/sub/directory"
+
+	import "launchpad.net/~user/project/branch"
+	import "launchpad.net/~user/project/branch/sub/directory"
+
+IBM DevOps Services (Git)
+
+	import "hub.jazz.net/git/user/project"
+	import "hub.jazz.net/git/user/project/sub/directory"
+
    
+
    
+For code hosted on other servers, import paths may either be qualified
+with the version control type, or the go tool can dynamically fetch
+the import path over https/http and discover where the code resides
+from a <meta> tag in the HTML.
+
    
+
    
+To declare the code location, an import path of the form
+
    
+
    repository.vcs/path
+
    
+
    
+specifies the given repository, with or without the .vcs suffix,
+using the named version control system, and then the path inside
+that repository.  The supported version control systems are:
+
    
+
    Bazaar      .bzr
+Git         .git
+Mercurial   .hg
+Subversion  .svn
+
    
+
    
+For example,
+
    
+
    import "example.org/user/foo.hg"
+
    
+
    
+denotes the root directory of the Mercurial repository at
+example.org/user/foo or foo.hg, and
+
    
+
    import "example.org/repo.git/foo/bar"
+
    
+
    
+denotes the foo/bar directory of the Git repository at
+example.org/repo or repo.git.
+
    
+
    
+When a version control system supports multiple protocols,
+each is tried in turn when downloading.  For example, a Git
+download tries https://, then git+ssh://.
+
    
+
    
+By default, downloads are restricted to known secure protocols
+(e.g. https, ssh). To override this setting for Git downloads, the
+GIT_ALLOW_PROTOCOL environment variable can be set (For more details see:
+'go help environment').
+
    
+
    
+If the import path is not a known code hosting site and also lacks a
+version control qualifier, the go tool attempts to fetch the import
+over https/http and looks for a <meta> tag in the document's HTML
+<head>.
+
    
+
    
+The meta tag has the form:
+
    
+
    <meta name="go-import" content="import-prefix vcs repo-root">
+
    
+
    
+The import-prefix is the import path corresponding to the repository
+root. It must be a prefix or an exact match of the package being
+fetched with "go get". If it's not an exact match, another http
+request is made at the prefix to verify the <meta> tags match.
+
    
+
    
+The meta tag should appear as early in the file as possible.
+In particular, it should appear before any raw JavaScript or CSS,
+to avoid confusing the go command's restricted parser.
+
    
+
    
+The vcs is one of "git", "hg", "svn", etc,
+
    
+
    
+The repo-root is the root of the version control system
+containing a scheme and not containing a .vcs qualifier.
+
    
+
    
+For example,
+
    
+
    import "example.org/pkg/foo"
+
    
+
    
+will result in the following requests:
+
    
+
    https://example.org/pkg/foo?go-get=1 (preferred)
+http://example.org/pkg/foo?go-get=1  (fallback, only with -insecure)
+
    
+
    
+If that page contains the meta tag
+
    
+
    <meta name="go-import" content="example.org git https://code.org/r/p/exproj">
+
    
+
    
+the go tool will verify that https://example.org/?go-get=1 contains the
+same meta tag and then git clone https://code.org/r/p/exproj into
+GOPATH/src/example.org.
+
    
+
    
+New downloaded packages are written to the first directory listed in the GOPATH
+environment variable (For more details see: 'go help gopath').
+
    
+
    
+The go command attempts to download the version of the
+package appropriate for the Go release being used.
+Run 'go help get' for more.
+
    
+
    Import path checking
    
+
    
+When the custom import path feature described above redirects to a
+known code hosting site, each of the resulting packages has two possible
+import paths, using the custom domain or the known hosting site.
+
    
+
    
+A package statement is said to have an "import comment" if it is immediately
+followed (before the next newline) by a comment of one of these two forms:
+
    
+
    package math // import "path"
+package math /* import "path" */
+
    
+
    
+The go command will refuse to install a package with an import comment
+unless it is being referred to by that import path. In this way, import comments
+let package authors make sure the custom import path is used and not a
+direct path to the underlying code hosting site.
+
    
+
    
+Import path checking is disabled for code found within vendor trees.
+This makes it possible to copy code into alternate locations in vendor trees
+without needing to update import comments.
+
    
+
    
+See https://golang.org/s/go14customimport for details.
+
    
+
    Description of package lists
    
+
    
+Many commands apply to a set of packages:
+
    
+
    go action [packages]
+
    
+
    
+Usually, [packages] is a list of import paths.
+
    
+
    
+An import path that is a rooted path or that begins with
+a . or .. element is interpreted as a file system path and
+denotes the package in that directory.
+
    
+
    
+Otherwise, the import path P denotes the package found in
+the directory DIR/src/P for some DIR listed in the GOPATH
+environment variable (For more details see: 'go help gopath').
+
    
+
    
+If no import paths are given, the action applies to the
+package in the current directory.
+
    
+
    
+There are four reserved names for paths that should not be used
+for packages to be built with the go tool:
+
    
+
    
+- "main" denotes the top-level package in a stand-alone executable.
+
    
+
    
+- "all" expands to all package directories found in all the GOPATH
+trees. For example, 'go list all' lists all the packages on the local
+system.
+
    
+
    
+- "std" is like all but expands to just the packages in the standard
+Go library.
+
    
+
    
+- "cmd" expands to the Go repository's commands and their
+internal libraries.
+
    
+
    
+Import paths beginning with "cmd/" only match source code in
+the Go repository.
+
    
+
    
+An import path is a pattern if it includes one or more "..." wildcards,
+each of which can match any string, including the empty string and
+strings containing slashes.  Such a pattern expands to all package
+directories found in the GOPATH trees with names matching the
+patterns.  As a special case, x/... matches x as well as x's subdirectories.
+For example, net/... expands to net and packages in its subdirectories.
+
    
+
    
+An import path can also name a package to be downloaded from
+a remote repository.  Run 'go help importpath' for details.
+
    
+
    
+Every package in a program must have a unique import path.
+By convention, this is arranged by starting each path with a
+unique prefix that belongs to you.  For example, paths used
+internally at Google all begin with 'google', and paths
+denoting remote repositories begin with the path to the code,
+such as 'github.com/user/repo'.
+
    
+
    
+Packages in a program need not have unique package names,
+but there are two reserved package names with special meaning.
+The name main indicates a command, not a library.
+Commands are built into binaries and cannot be imported.
+The name documentation indicates documentation for
+a non-Go program in the directory. Files in package documentation
+are ignored by the go command.
+
    
+
    
+As a special case, if the package list is a list of .go files from a
+single directory, the command is applied to a single synthesized
+package made up of exactly those files, ignoring any build constraints
+in those files and ignoring any other files in the directory.
+
    
+
    
+Directory and file names that begin with "." or "_" are ignored
+by the go tool, as are directories named "testdata".
+
    
+
    Description of testing flags
    
+
    
+The 'go test' command takes both flags that apply to 'go test' itself
+and flags that apply to the resulting test binary.
+
    
+
    
+Several of the flags control profiling and write an execution profile
+suitable for "go tool pprof"; run "go tool pprof -h" for more
+information.  The --alloc_space, --alloc_objects, and --show_bytes
+options of pprof control how the information is presented.
+
    
+
    
+The following flags are recognized by the 'go test' command and
+control the execution of any test:
+
    
+
    -bench regexp
+    Run (sub)benchmarks matching a regular expression.
+    The given regular expression is split into smaller ones by
+    top-level '/', where each must match the corresponding part of a
+    benchmark's identifier.
+    By default, no benchmarks run. To run all benchmarks,
+    use '-bench .' or '-bench=.'.
+
+-benchtime t
+    Run enough iterations of each benchmark to take t, specified
+    as a time.Duration (for example, -benchtime 1h30s).
+    The default is 1 second (1s).
+
+-count n
+    Run each test and benchmark n times (default 1).
+    If -cpu is set, run n times for each GOMAXPROCS value.
+    Examples are always run once.
+
+-cover
+    Enable coverage analysis.
+
+-covermode set,count,atomic
+    Set the mode for coverage analysis for the package[s]
+    being tested. The default is "set" unless -race is enabled,
+    in which case it is "atomic".
+    The values:
+	set: bool: does this statement run?
+	count: int: how many times does this statement run?
+	atomic: int: count, but correct in multithreaded tests;
+		significantly more expensive.
+    Sets -cover.
+
+-coverpkg pkg1,pkg2,pkg3
+    Apply coverage analysis in each test to the given list of packages.
+    The default is for each test to analyze only the package being tested.
+    Packages are specified as import paths.
+    Sets -cover.
+
+-cpu 1,2,4
+    Specify a list of GOMAXPROCS values for which the tests or
+    benchmarks should be executed.  The default is the current value
+    of GOMAXPROCS.
+
+-parallel n
+    Allow parallel execution of test functions that call t.Parallel.
+    The value of this flag is the maximum number of tests to run
+    simultaneously; by default, it is set to the value of GOMAXPROCS.
+    Note that -parallel only applies within a single test binary.
+    The 'go test' command may run tests for different packages
+    in parallel as well, according to the setting of the -p flag
+    (see 'go help build').
+
+-run regexp
+    Run only those tests and examples matching the regular expression.
+    For tests the regular expression is split into smaller ones by
+    top-level '/', where each must match the corresponding part of a
+    test's identifier.
+
+-short
+    Tell long-running tests to shorten their run time.
+    It is off by default but set during all.bash so that installing
+    the Go tree can run a sanity check but not spend time running
+    exhaustive tests.
+
+-timeout t
+    If a test runs longer than t, panic.
+    The default is 10 minutes (10m).
+
+-v
+    Verbose output: log all tests as they are run. Also print all
+    text from Log and Logf calls even if the test succeeds.
+
    
+
    
+The following flags are also recognized by 'go test' and can be used to
+profile the tests during execution:
+
    
+
    -benchmem
+    Print memory allocation statistics for benchmarks.
+
+-blockprofile block.out
+    Write a goroutine blocking profile to the specified file
+    when all tests are complete.
+    Writes test binary as -c would.
+
+-blockprofilerate n
+    Control the detail provided in goroutine blocking profiles by
+    calling runtime.SetBlockProfileRate with n.
+    See 'go doc runtime.SetBlockProfileRate'.
+    The profiler aims to sample, on average, one blocking event every
+    n nanoseconds the program spends blocked.  By default,
+    if -test.blockprofile is set without this flag, all blocking events
+    are recorded, equivalent to -test.blockprofilerate=1.
+
+-coverprofile cover.out
+    Write a coverage profile to the file after all tests have passed.
+    Sets -cover.
+
+-cpuprofile cpu.out
+    Write a CPU profile to the specified file before exiting.
+    Writes test binary as -c would.
+
+-memprofile mem.out
+    Write a memory profile to the file after all tests have passed.
+    Writes test binary as -c would.
+
+-memprofilerate n
+    Enable more precise (and expensive) memory profiles by setting
+    runtime.MemProfileRate.  See 'go doc runtime.MemProfileRate'.
+    To profile all memory allocations, use -test.memprofilerate=1
+    and pass --alloc_space flag to the pprof tool.
+
+-mutexprofile mutex.out
+    Write a mutex contention profile to the specified file
+    when all tests are complete.
+    Writes test binary as -c would.
+
+-mutexprofilefraction n
+    Sample 1 in n stack traces of goroutines holding a
+    contended mutex.
+
+-outputdir directory
+    Place output files from profiling in the specified directory,
+    by default the directory in which "go test" is running.
+
+-trace trace.out
+    Write an execution trace to the specified file before exiting.
+
    
+
    
+Each of these flags is also recognized with an optional 'test.' prefix,
+as in -test.v. When invoking the generated test binary (the result of
+'go test -c') directly, however, the prefix is mandatory.
+
    
+
    
+The 'go test' command rewrites or removes recognized flags,
+as appropriate, both before and after the optional package list,
+before invoking the test binary.
+
    
+
    
+For instance, the command
+
    
+
    go test -v -myflag testdata -cpuprofile=prof.out -x
+
    
+
    
+will compile the test binary and then run it as
+
    
+
    pkg.test -test.v -myflag testdata -test.cpuprofile=prof.out
+
    
+
    
+(The -x flag is removed because it applies only to the go command's
+execution, not to the test itself.)
+
    
+
    
+The test flags that generate profiles (other than for coverage) also
+leave the test binary in pkg.test for use when analyzing the profiles.
+
    
+
    
+When 'go test' runs a test binary, it does so from within the
+corresponding package's source code directory. Depending on the test,
+it may be necessary to do the same when invoking a generated test
+binary directly.
+
    
+
    
+The command-line package list, if present, must appear before any
+flag not known to the go test command. Continuing the example above,
+the package list would have to appear before -myflag, but could appear
+on either side of -v.
+
    
+
    
+To keep an argument for a test binary from being interpreted as a
+known flag or a package name, use -args (see 'go help test') which
+passes the remainder of the command line through to the test binary
+uninterpreted and unaltered.
+
    
+
    
+For instance, the command
+
    
+
    go test -v -args -x -v
+
    
+
    
+will compile the test binary and then run it as
+
    
+
    pkg.test -test.v -x -v
+
    
+
    
+Similarly,
+
    
+
    go test -args math
+
    
+
    
+will compile the test binary and then run it as
+
    
+
    pkg.test math
+
    
+
    
+In the first example, the -x and the second -v are passed through to the
+test binary unchanged and with no effect on the go command itself.
+In the second example, the argument math is passed through to the test
+binary, instead of being interpreted as the package list.
+
    
+
    Description of testing functions
    
+
    
+The 'go test' command expects to find test, benchmark, and example functions
+in the "*_test.go" files corresponding to the package under test.
+
    
+
    
+A test function is one named TestXXX (where XXX is any alphanumeric string
+not starting with a lower case letter) and should have the signature,
+
    
+
    func TestXXX(t *testing.T) { ... }
+
    
+
    
+A benchmark function is one named BenchmarkXXX and should have the signature,
+
    
+
    func BenchmarkXXX(b *testing.B) { ... }
+
    
+
    
+An example function is similar to a test function but, instead of using
+*testing.T to report success or failure, prints output to os.Stdout.
+If the last comment in the function starts with "Output:" then the output
+is compared exactly against the comment (see examples below). If the last
+comment begins with "Unordered output:" then the output is compared to the
+comment, however the order of the lines is ignored. An example with no such
+comment is compiled but not executed. An example with no text after
+"Output:" is compiled, executed, and expected to produce no output.
+
    
+
    
+Godoc displays the body of ExampleXXX to demonstrate the use
+of the function, constant, or variable XXX.  An example of a method M with
+receiver type T or *T is named ExampleT_M.  There may be multiple examples
+for a given function, constant, or variable, distinguished by a trailing _xxx,
+where xxx is a suffix not beginning with an upper case letter.
+
    
+
    
+Here is an example of an example:
+
    
+
    func ExamplePrintln() {
+	Println("The output of\nthis example.")
+	// Output: The output of
+	// this example.
+}
+
    
+
    
+Here is another example where the ordering of the output is ignored:
+
    
+
    func ExamplePerm() {
+	for _, value := range Perm(4) {
+		fmt.Println(value)
+	}
+
+	// Unordered output: 4
+	// 2
+	// 1
+	// 3
+	// 0
+}
+
    
+
    
+The entire test file is presented as the example when it contains a single
+example function, at least one other function, type, variable, or constant
+declaration, and no test or benchmark functions.
+
    
+
    
+See the documentation of the testing package for more information.

+// TODO: turn off the serve goroutine when idle, so
+// an idle conn only has the readFrames goroutine active. (which could
+// also be optimized probably to pin less memory in crypto/tls). This
+// would involve tracking when the serve goroutine is active (atomic
+// int32 read/CAS probably?) and starting it up when frames arrive,
+// and shutting it down when all handlers exit. the occasional PING
+// packets could use time.AfterFunc to call sc.wakeStartServeLoop()
+// (which is a no-op if already running) and then queue the PING write
+// as normal. The serve loop would then exit in most cases (if no
+// Handlers running) and not be woken up again until the PING packet
+// returns.
+
+// TODO (maybe): add a mechanism for Handlers to going into
+// half-closed-local mode (rw.(io.Closer) test?) but not exit their
+// handler, and continue to be able to read from the
+// Request.Body. This would be a somewhat semantic change from HTTP/1
+// (or at least what we expose in net/http), so I'd probably want to
+// add it there too. For now, this package says that returning from

+        This specification describes an optimized expression of the semantics of the Hypertext
+        Transfer Protocol (HTTP). HTTP/2 enables a more efficient use of network resources and a
+        reduced perception of latency by introducing header field compression and allowing multiple
+        concurrent messages on the same connection. It also introduces unsolicited push of
+        representations from servers to clients.
+      
+      
+        This specification is an alternative to, but does not obsolete, the HTTP/1.1 message syntax.
+        HTTP's existing semantics remain unchanged.
+      
+

+        Discussion of this draft takes place on the HTTPBIS working group mailing list
+        (ietf-http-wg@w3.org), which is archived at .

+      
+
+  
+    
    
+
+      
+        The Hypertext Transfer Protocol (HTTP) is a wildly successful protocol. However, the
+        HTTP/1.1 message format () has
+        several characteristics that have a negative overall effect on application performance
+        today.
+      
+      
+        In particular, HTTP/1.0 allowed only one request to be outstanding at a time on a given
+        TCP connection. HTTP/1.1 added request pipelining, but this only partially addressed
+        request concurrency and still suffers from head-of-line blocking. Therefore, HTTP/1.1
+        clients that need to make many requests typically use multiple connections to a server in
+        order to achieve concurrency and thereby reduce latency.
+      
+      
+        Furthermore, HTTP header fields are often repetitive and verbose, causing unnecessary
+        network traffic, as well as causing the initial TCP congestion
+        window to quickly fill. This can result in excessive latency when multiple requests are
+        made on a new TCP connection.
+      
+      
+        HTTP/2 addresses these issues by defining an optimized mapping of HTTP's semantics to an
+        underlying connection. Specifically, it allows interleaving of request and response
+        messages on the same connection and uses an efficient coding for HTTP header fields. It
+        also allows prioritization of requests, letting more important requests complete more
+        quickly, further improving performance.
+      
+      
+        The resulting protocol is more friendly to the network, because fewer TCP connections can
+        be used in comparison to HTTP/1.x. This means less competition with other flows, and
+        longer-lived connections, which in turn leads to better utilization of available network
+        capacity.
+      
+      
+        Finally, HTTP/2 also enables more efficient processing of messages through use of binary
+        message framing.
+      
+    
    
+
+    
    
+      
+        HTTP/2 provides an optimized transport for HTTP semantics.  HTTP/2 supports all of the core
+        features of HTTP/1.1, but aims to be more efficient in several ways.
+      
+      
+        The basic protocol unit in HTTP/2 is a frame.  Each frame
+        type serves a different purpose.  For example, HEADERS and
+        DATA frames form the basis of HTTP requests and
+        responses; other frame types like SETTINGS,
+        WINDOW_UPDATE, and PUSH_PROMISE are used in support of other
+        HTTP/2 features.
+      
+      
+        Multiplexing of requests is achieved by having each HTTP request-response exchange
+        associated with its own stream. Streams are largely
+        independent of each other, so a blocked or stalled request or response does not prevent
+        progress on other streams.
+      
+      
+        Flow control and prioritization ensure that it is possible to efficiently use multiplexed
+        streams.  Flow control helps to ensure that only data that
+        can be used by a receiver is transmitted.  Prioritization ensures that limited resources can be directed
+        to the most important streams first.
+      
+      
+        HTTP/2 adds a new interaction mode, whereby a server can push
+        responses to a client.  Server push allows a server to speculatively send a client
+        data that the server anticipates the client will need, trading off some network usage
+        against a potential latency gain.  The server does this by synthesizing a request, which it
+        sends as a PUSH_PROMISE frame.  The server is then able to send a response to
+        the synthetic request on a separate stream.
+      
+      
+        Frames that contain HTTP header fields are compressed.
+        HTTP requests can be highly redundant, so compression can reduce the size of requests and
+        responses significantly.
+      
+
+      
    
+        
+          The HTTP/2 specification is split into four parts:
+          
+            
+              Starting HTTP/2 covers how an HTTP/2 connection is
+              initiated.
+            
+            
+              The framing and streams layers describe the way HTTP/2 frames are
+              structured and formed into multiplexed streams.
+            
+            
+              Frame and error
+              definitions include details of the frame and error types used in HTTP/2.
+            
+            
+              HTTP mappings and additional
+              requirements describe how HTTP semantics are expressed using frames and
+              streams.
+          
+          
+        
+        
+          While some of the frame and stream layer concepts are isolated from HTTP, this
+          specification does not define a completely generic framing layer. The framing and streams
+          layers are tailored to the needs of the HTTP protocol and server push.
+        
+      
    
+
+      
    
+        
+          The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD
+          NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as
+          described in RFC 2119.
+        
+        
+          All numeric values are in network byte order.  Values are unsigned unless otherwise
+          indicated.  Literal values are provided in decimal or hexadecimal as appropriate.
+          Hexadecimal literals are prefixed with 0x to distinguish them
+          from decimal literals.
+        
+        
+          The following terms are used:
+          
+            
+              The endpoint initiating the HTTP/2 connection.
+            
+            
+              A transport-layer connection between two endpoints.
+            
+            
+              An error that affects the entire HTTP/2 connection.
+            
+            
+              Either the client or server of the connection.
+            
+            
+              The smallest unit of communication within an HTTP/2 connection, consisting of a header
+              and a variable-length sequence of octets structured according to the frame type.
+            
+            
+              An endpoint.  When discussing a particular endpoint, "peer" refers to the endpoint
+              that is remote to the primary subject of discussion.
+            
+            
+              An endpoint that is receiving frames.
+            
+            
+              An endpoint that is transmitting frames.
+            
+            
+              The endpoint which did not initiate the HTTP/2 connection.
+            
+            
+              A bi-directional flow of frames across a virtual channel within the HTTP/2 connection.
+            
+            
+              An error on the individual HTTP/2 stream.
+            
+          
+        
+        
+          Finally, the terms "gateway", "intermediary", "proxy", and "tunnel" are defined
+          in .
+        
+      
    
+    
    
+
+    
    
+      
+        An HTTP/2 connection is an application layer protocol running on top of a TCP connection
+        (). The client is the TCP connection initiator.
+      
+      
+        HTTP/2 uses the same "http" and "https" URI schemes used by HTTP/1.1. HTTP/2 shares the same
+        default port numbers: 80 for "http" URIs and 443 for "https" URIs.  As a result,
+        implementations processing requests for target resource URIs like http://example.org/foo or https://example.com/bar are required to first discover whether the
+        upstream server (the immediate peer to which the client wishes to establish a connection)
+        supports HTTP/2.
+      
+
+      
+        The means by which support for HTTP/2 is determined is different for "http" and "https"
+        URIs. Discovery for "http" URIs is described in .  Discovery
+        for "https" URIs is described in .
+      
+
+      
    
+        
+          The protocol defined in this document has two identifiers.
+          
+            
+              
+                The string "h2" identifies the protocol where HTTP/2 uses TLS.  This identifier is used in the TLS application layer protocol negotiation extension (ALPN)
+                field and any place that HTTP/2 over TLS is identified.
+              
+              
+                The "h2" string is serialized into an ALPN protocol identifier as the two octet
+                sequence: 0x68, 0x32.
+              
+            
+            
+              
+                The string "h2c" identifies the protocol where HTTP/2 is run over cleartext TCP.
+                This identifier is used in the HTTP/1.1 Upgrade header field and any place that
+                HTTP/2 over TCP is identified.
+              
+            
+          
+        
+        
+          Negotiating "h2" or "h2c" implies the use of the transport, security, framing and message
+          semantics described in this document.
+        
+        
+          RFC Editor's Note: please remove the remainder of this section prior to the
+          publication of a final version of this document.
+        
+        
+          Only implementations of the final, published RFC can identify themselves as "h2" or "h2c".
+          Until such an RFC exists, implementations MUST NOT identify themselves using these
+          strings.
+        
+        
+          Examples and text throughout the rest of this document use "h2" as a matter of
+          editorial convenience only.  Implementations of draft versions MUST NOT identify using
+          this string.
+        
+        
+          Implementations of draft versions of the protocol MUST add the string "-" and the
+          corresponding draft number to the identifier. For example, draft-ietf-httpbis-http2-11
+          over TLS is identified using the string "h2-11".
+        
+        
+          Non-compatible experiments that are based on these draft versions MUST append the string
+          "-" and an experiment name to the identifier.  For example, an experimental implementation
+          of packet mood-based encoding based on draft-ietf-httpbis-http2-09 might identify itself
+          as "h2-09-emo".  Note that any label MUST conform to the "token" syntax defined in
+          .  Experimenters are
+          encouraged to coordinate their experiments on the ietf-http-wg@w3.org mailing list.
+        
+      
    
+
+      
    
+        
+          A client that makes a request for an "http" URI without prior knowledge about support for
+          HTTP/2 uses the HTTP Upgrade mechanism ().  The client makes an HTTP/1.1 request that includes an Upgrade
+          header field identifying HTTP/2 with the "h2c" token.  The HTTP/1.1 request MUST include
+          exactly one HTTP2-Settings header field.
+        
+        
    
+          For example:
+          
+
+]]>
+        
    
+        
+          Requests that contain an entity body MUST be sent in their entirety before the client can
+          send HTTP/2 frames.  This means that a large request entity can block the use of the
+          connection until it is completely sent.
+        
+        
+          If concurrency of an initial request with subsequent requests is important, an OPTIONS
+          request can be used to perform the upgrade to HTTP/2, at the cost of an additional
+          round-trip.
+        
+        
+          A server that does not support HTTP/2 can respond to the request as though the Upgrade
+          header field were absent:
+        
+        
    
+          
+HTTP/1.1 200 OK
+Content-Length: 243
+Content-Type: text/html
+
+...
+
+        
    
+        
+          A server MUST ignore a "h2" token in an Upgrade header field.  Presence of a token with
+          "h2" implies HTTP/2 over TLS, which is instead negotiated as described in .
+        
+        
+          A server that supports HTTP/2 can accept the upgrade with a 101 (Switching Protocols)
+          response.  After the empty line that terminates the 101 response, the server can begin
+          sending HTTP/2 frames.  These frames MUST include a response to the request that initiated
+          the Upgrade.
+        
+
+        
    
+          
+            For example:
+          
+          
+HTTP/1.1 101 Switching Protocols
+Connection: Upgrade
+Upgrade: h2c
+
+[ HTTP/2 connection ...
+
+        
    
+        
+          The first HTTP/2 frame sent by the server is a SETTINGS frame () as the server connection preface (). Upon receiving the 101 response, the client sends a connection preface, which includes a
+          SETTINGS frame.
+        
+        
+          The HTTP/1.1 request that is sent prior to upgrade is assigned stream identifier 1 and is
+          assigned default priority values.  Stream 1 is
+          implicitly half closed from the client toward the server, since the request is completed
+          as an HTTP/1.1 request.  After commencing the HTTP/2 connection, stream 1 is used for the
+          response.
+        
+
+        
    
+          
+            A request that upgrades from HTTP/1.1 to HTTP/2 MUST include exactly one HTTP2-Settings header field.  The HTTP2-Settings header field is a connection-specific header field
+            that includes parameters that govern the HTTP/2 connection, provided in anticipation of
+            the server accepting the request to upgrade.
+          
+          
    
+            
+          
    
+          
+            A server MUST NOT upgrade the connection to HTTP/2 if this header field is not present,
+            or if more than one is present. A server MUST NOT send this header field.
+          
+
+          
+            The content of the HTTP2-Settings header field is the
+            payload of a SETTINGS frame (), encoded as a
+            base64url string (that is, the URL- and filename-safe Base64 encoding described in , with any trailing '=' characters omitted).  The
+            ABNF production for token68 is
+            defined in .
+          
+          
+            Since the upgrade is only intended to apply to the immediate connection, a client
+            sending HTTP2-Settings MUST also send HTTP2-Settings as a connection option in the Connection header field to prevent it from being forwarded
+            downstream.
+          
+          
+            A server decodes and interprets these values as it would any other
+            SETTINGS frame.  Acknowledgement of the
+            SETTINGS parameters is not necessary, since a 101 response serves as implicit
+            acknowledgment.  Providing these values in the Upgrade request gives a client an
+            opportunity to provide parameters prior to receiving any frames from the server.
+          
+        
    
+      
    
+
+      
    
+        
+          A client that makes a request to an "https" URI uses TLS
+          with the application layer protocol negotiation extension.
+        
+        
+          HTTP/2 over TLS uses the "h2" application token.  The "h2c" token MUST NOT be sent by a
+          client or selected by a server.
+        
+        
+          Once TLS negotiation is complete, both the client and the server send a connection preface.
+        
+      
    
+
+      
    
+        
+          A client can learn that a particular server supports HTTP/2 by other means.  For example,
+           describes a mechanism for advertising this capability.
+        
+        
+          A client MAY immediately send HTTP/2 frames to a server that is known to support HTTP/2,
+          after the connection preface; a server can
+          identify such a connection by the presence of the connection preface. This only affects
+          the establishment of HTTP/2 connections over cleartext TCP; implementations that support
+          HTTP/2 over TLS MUST use protocol negotiation in TLS.
+        
+        
+          Without additional information, prior support for HTTP/2 is not a strong signal that a
+          given server will support HTTP/2 for future connections. For example, it is possible for
+          server configurations to change, for configurations to differ between instances in
+          clustered servers, or for network conditions to change.
+        
+      
    
+
+      
    
+        
+          Upon establishment of a TCP connection and determination that HTTP/2 will be used by both
+          peers, each endpoint MUST send a connection preface as a final confirmation and to
+          establish the initial SETTINGS parameters for the HTTP/2 connection.  The client and
+          server each send a different connection preface.
+        
+        
+          The client connection preface starts with a sequence of 24 octets, which in hex notation
+          are:
+        
+        
    
+          
+        
    
+        
+          (the string PRI * HTTP/2.0\r\n\r\nSM\r\n\r\n).  This sequence
+          is followed by a SETTINGS frame ().  The
+          SETTINGS frame MAY be empty.  The client sends the client connection
+          preface immediately upon receipt of a 101 Switching Protocols response (indicating a
+          successful upgrade), or as the first application data octets of a TLS connection. If
+          starting an HTTP/2 connection with prior knowledge of server support for the protocol, the
+          client connection preface is sent upon connection establishment.
+        
+        
+          
+            
+              The client connection preface is selected so that a large proportion of HTTP/1.1 or
+              HTTP/1.0 servers and intermediaries do not attempt to process further frames.  Note
+              that this does not address the concerns raised in .
+            
+          
+        
+        
+          The server connection preface consists of a potentially empty SETTINGS
+          frame () that MUST be the first frame the server sends in the
+          HTTP/2 connection.
+        
+        
+          The SETTINGS frames received from a peer as part of the connection preface
+          MUST be acknowledged (see ) after sending the connection
+          preface.
+        
+        
+          To avoid unnecessary latency, clients are permitted to send additional frames to the
+          server immediately after sending the client connection preface, without waiting to receive
+          the server connection preface.  It is important to note, however, that the server
+          connection preface SETTINGS frame might include parameters that necessarily
+          alter how a client is expected to communicate with the server. Upon receiving the
+          SETTINGS frame, the client is expected to honor any parameters established.
+          In some configurations, it is possible for the server to transmit SETTINGS
+          before the client sends additional frames, providing an opportunity to avoid this issue.
+        
+        
+          Clients and servers MUST treat an invalid connection preface as a connection error of type
+          PROTOCOL_ERROR.  A GOAWAY frame ()
+          MAY be omitted in this case, since an invalid preface indicates that the peer is not using
+          HTTP/2.
+        
+      
    
+    
    
+
+    
    
+      
+        Once the HTTP/2 connection is established, endpoints can begin exchanging frames.
+      
+
+      
    
+        
+          All frames begin with a fixed 9-octet header followed by a variable-length payload.
+        
+        
    
+          
+        
    
+        
+          The fields of the frame header are defined as:
+          
+            
+              
+                The length of the frame payload expressed as an unsigned 24-bit integer.  Values
+                greater than 214 (16,384) MUST NOT be sent unless the receiver has
+                set a larger value for SETTINGS_MAX_FRAME_SIZE.
+              
+              
+                The 9 octets of the frame header are not included in this value.
+              
+            
+            
+              
+                The 8-bit type of the frame.  The frame type determines the format and semantics of
+                the frame.  Implementations MUST ignore and discard any frame that has a type that
+                is unknown.
+              
+            
+            
+              
+                An 8-bit field reserved for frame-type specific boolean flags.
+              
+              
+                Flags are assigned semantics specific to the indicated frame type.  Flags that have
+                no defined semantics for a particular frame type MUST be ignored, and MUST be left
+                unset (0) when sending.
+              
+            
+            
+              
+                A reserved 1-bit field.  The semantics of this bit are undefined and the bit MUST
+                remain unset (0) when sending and MUST be ignored when receiving.
+              
+            
+            
+              
+                A 31-bit stream identifier (see ).  The value 0 is
+                reserved for frames that are associated with the connection as a whole as opposed to
+                an individual stream.
+              
+            
+          
+        
+        
+          The structure and content of the frame payload is dependent entirely on the frame type.
+        
+      
    
+
+      
    
+        
+          The size of a frame payload is limited by the maximum size that a receiver advertises in
+          the SETTINGS_MAX_FRAME_SIZE setting.  This setting can have any value
+          between 214 (16,384) and 224-1 (16,777,215) octets,
+          inclusive.
+        
+        
+          All implementations MUST be capable of receiving and minimally processing frames up to
+          214 octets in length, plus the 9 octet frame
+          header.  The size of the frame header is not included when describing frame sizes.
+          
+            
+              Certain frame types, such as PING, impose additional limits
+              on the amount of payload data allowed.
+            
+          
+        
+        
+          If a frame size exceeds any defined limit, or is too small to contain mandatory frame
+          data, the endpoint MUST send a FRAME_SIZE_ERROR error. A frame size error
+          in a frame that could alter the state of the entire connection MUST be treated as a connection error; this includes any frame carrying
+          a header block (that is, HEADERS,
+          PUSH_PROMISE, and CONTINUATION), SETTINGS,
+          and any WINDOW_UPDATE frame with a stream identifier of 0.
+        
+        
+          Endpoints are not obligated to use all available space in a frame. Responsiveness can be
+          improved by using frames that are smaller than the permitted maximum size. Sending large
+          frames can result in delays in sending time-sensitive frames (such
+          RST_STREAM, WINDOW_UPDATE, or PRIORITY)
+          which if blocked by the transmission of a large frame, could affect performance.
+        
+      
    
+
+      
    
+        
+          Just as in HTTP/1, a header field in HTTP/2 is a name with one or more associated values.
+          They are used within HTTP request and response messages as well as server push operations
+          (see ).
+        
+        
+          Header lists are collections of zero or more header fields.  When transmitted over a
+          connection, a header list is serialized into a header block using HTTP Header Compression.  The serialized header block is then
+          divided into one or more octet sequences, called header block fragments, and transmitted
+          within the payload of HEADERS, PUSH_PROMISE or CONTINUATION frames.
+        
+        
+          The Cookie header field is treated specially by the HTTP
+          mapping (see ).
+        
+        
+          A receiving endpoint reassembles the header block by concatenating its fragments, then
+          decompresses the block to reconstruct the header list.
+        
+        
+          A complete header block consists of either:
+          
+            
+              a single HEADERS or PUSH_PROMISE frame,
+              with the END_HEADERS flag set, or
+            
+            
+              a HEADERS or PUSH_PROMISE frame with the END_HEADERS
+              flag cleared and one or more CONTINUATION frames,
+              where the last CONTINUATION frame has the END_HEADERS flag set.
+            
+          
+        
+        
+          Header compression is stateful.  One compression context and one decompression context is
+          used for the entire connection.  Each header block is processed as a discrete unit.
+          Header blocks MUST be transmitted as a contiguous sequence of frames, with no interleaved
+          frames of any other type or from any other stream.  The last frame in a sequence of
+          HEADERS or CONTINUATION frames MUST have the END_HEADERS
+          flag set.  The last frame in a sequence of PUSH_PROMISE or
+          CONTINUATION frames MUST have the END_HEADERS flag set.  This allows a
+          header block to be logically equivalent to a single frame.
+        
+        
+          Header block fragments can only be sent as the payload of HEADERS,
+          PUSH_PROMISE or CONTINUATION frames, because these frames
+          carry data that can modify the compression context maintained by a receiver.  An endpoint
+          receiving HEADERS, PUSH_PROMISE or
+          CONTINUATION frames MUST reassemble header blocks and perform decompression
+          even if the frames are to be discarded.  A receiver MUST terminate the connection with a
+          connection error of type
+          COMPRESSION_ERROR if it does not decompress a header block.
+        
+      
    
+    
    
+
+    
    
+      
+        A "stream" is an independent, bi-directional sequence of frames exchanged between the client
+        and server within an HTTP/2 connection.  Streams have several important characteristics:
+        
+          
+            A single HTTP/2 connection can contain multiple concurrently open streams, with either
+            endpoint interleaving frames from multiple streams.
+          
+          
+            Streams can be established and used unilaterally or shared by either the client or
+            server.
+          
+          
+            Streams can be closed by either endpoint.
+          
+          
+            The order in which frames are sent on a stream is significant. Recipients process frames
+            in the order they are received.  In particular, the order of HEADERS,
+            and DATA frames is semantically significant.
+          
+          
+            Streams are identified by an integer.  Stream identifiers are assigned to streams by the
+            endpoint initiating the stream.
+          
+        
+      
+
+      
    
+        
+          The lifecycle of a stream is shown in .

+          
+        
    
+
+        
+          Note that this diagram shows stream state transitions and the frames and flags that affect
+          those transitions only.  In this regard, CONTINUATION frames do not result
+          in state transitions; they are effectively part of the HEADERS or
+          PUSH_PROMISE that they follow.  For this purpose, the END_STREAM flag is
+          processed as a separate event to the frame that bears it; a HEADERS frame
+          with the END_STREAM flag set can cause two state transitions.
+        
+        
+          Both endpoints have a subjective view of the state of a stream that could be different
+          when frames are in transit.  Endpoints do not coordinate the creation of streams; they are
+          created unilaterally by either endpoint.  The negative consequences of a mismatch in
+          states are limited to the "closed" state after sending RST_STREAM, where
+          frames might be received for some time after closing.
+        
+        
+          Streams have the following states:
+          
+
+            
+              
+                
+                All streams start in the "idle" state.  In this state, no frames have been
+                exchanged.
+              
+              
+                The following transitions are valid from this state:
+                
+                  
+                    Sending or receiving a HEADERS frame causes the stream to become
+                    "open".  The stream identifier is selected as described in .  The same HEADERS frame can also
+                    cause a stream to immediately become "half closed".
+                  
+                  
+                    Sending a PUSH_PROMISE frame marks the associated stream for
+                    later use.  The stream state for the reserved stream transitions to "reserved
+                    (local)".
+                  
+                  
+                    Receiving a PUSH_PROMISE frame marks the associated stream as
+                    reserved by the remote peer.  The state of the stream becomes "reserved
+                    (remote)".
+                  
+                
+              
+              
+                Receiving any frames other than HEADERS or
+                PUSH_PROMISE on a stream in this state MUST be treated as a connection error of type
+                PROTOCOL_ERROR.
+              
+            
+
+            
+              
+                
+                A stream in the "reserved (local)" state is one that has been promised by sending a
+                PUSH_PROMISE frame.  A PUSH_PROMISE frame reserves an
+                idle stream by associating the stream with an open stream that was initiated by the
+                remote peer (see ).
+              
+              
+                In this state, only the following transitions are possible:
+                
+                  
+                    The endpoint can send a HEADERS frame.  This causes the stream to
+                    open in a "half closed (remote)" state.
+                  
+                  
+                    Either endpoint can send a RST_STREAM frame to cause the stream
+                    to become "closed".  This releases the stream reservation.
+                  
+                
+              
+              
+                An endpoint MUST NOT send any type of frame other than HEADERS or
+                RST_STREAM in this state.
+              
+              
+                A PRIORITY frame MAY be received in this state.  Receiving any type
+                of frame other than RST_STREAM or PRIORITY on a stream
+                in this state MUST be treated as a connection
+                error of type PROTOCOL_ERROR.
+              
+            
+
+            
+              
+                
+                A stream in the "reserved (remote)" state has been reserved by a remote peer.
+              
+              
+                In this state, only the following transitions are possible:
+                
+                  
+                    Receiving a HEADERS frame causes the stream to transition to
+                    "half closed (local)".
+                  
+                  
+                    Either endpoint can send a RST_STREAM frame to cause the stream
+                    to become "closed".  This releases the stream reservation.
+                  
+                
+              
+              
+                An endpoint MAY send a PRIORITY frame in this state to reprioritize
+                the reserved stream.  An endpoint MUST NOT send any type of frame other than
+                RST_STREAM, WINDOW_UPDATE, or PRIORITY
+                in this state.
+              
+              
+                Receiving any type of frame other than HEADERS or
+                RST_STREAM on a stream in this state MUST be treated as a connection error of type
+                PROTOCOL_ERROR.
+              
+            
+

+              
+                
+                A stream in the "open" state may be used by both peers to send frames of any type.
+                In this state, sending peers observe advertised stream
+                level flow control limits.
+              
+              
+                From this state either endpoint can send a frame with an END_STREAM flag set, which
+                causes the stream to transition into one of the "half closed" states: an endpoint
+                sending an END_STREAM flag causes the stream state to become "half closed (local)";
+                an endpoint receiving an END_STREAM flag causes the stream state to become "half
+                closed (remote)".
+              
+              
+                Either endpoint can send a RST_STREAM frame from this state, causing
+                it to transition immediately to "closed".

+

+                A stream that is in the "half closed (local)" state cannot be used for sending
+                frames.  Only WINDOW_UPDATE, PRIORITY and
+                RST_STREAM frames can be sent in this state.
+              
+              
+                A stream transitions from this state to "closed" when a frame that contains an
+                END_STREAM flag is received, or when either peer sends a RST_STREAM
+                frame.
+              
+              
+                A receiver can ignore WINDOW_UPDATE frames in this state, which might
+                arrive for a short period after a frame bearing the END_STREAM flag is sent.
+              
+              
+                PRIORITY frames received in this state are used to reprioritize
+                streams that depend on the current stream.

+              
+                
+                A stream that is "half closed (remote)" is no longer being used by the peer to send
+                frames.  In this state, an endpoint is no longer obligated to maintain a receiver
+                flow control window if it performs flow control.
+              
+              
+                If an endpoint receives additional frames for a stream that is in this state, other
+                than WINDOW_UPDATE, PRIORITY or
+                RST_STREAM, it MUST respond with a stream error of type
+                STREAM_CLOSED.
+              
+              
+                A stream that is "half closed (remote)" can be used by the endpoint to send frames
+                of any type. In this state, the endpoint continues to observe advertised stream level flow control limits.
+              
+              
+                A stream can transition from this state to "closed" by sending a frame that contains
+                an END_STREAM flag, or when either peer sends a RST_STREAM frame.
+              
+            
+
+            
+              
+                
+                The "closed" state is the terminal state.
+              
+              
+                An endpoint MUST NOT send frames other than PRIORITY on a closed
+                stream.  An endpoint that receives any frame other than PRIORITY
+                after receiving a RST_STREAM MUST treat that as a stream error of type
+                STREAM_CLOSED.  Similarly, an endpoint that receives any frames after
+                receiving a frame with the END_STREAM flag set MUST treat that as a connection error of type
+                STREAM_CLOSED, unless the frame is permitted as described below.
+              
+              
+                WINDOW_UPDATE or RST_STREAM frames can be received in
+                this state for a short period after a DATA or HEADERS
+                frame containing an END_STREAM flag is sent.  Until the remote peer receives and
+                processes RST_STREAM or the frame bearing the END_STREAM flag, it
+                might send frames of these types.  Endpoints MUST ignore
+                WINDOW_UPDATE or RST_STREAM frames received in this
+                state, though endpoints MAY choose to treat frames that arrive a significant time
+                after sending END_STREAM as a connection
+                error of type PROTOCOL_ERROR.
+              
+              
+                PRIORITY frames can be sent on closed streams to prioritize streams
+                that are dependent on the closed stream.  Endpoints SHOULD process
+                PRIORITY frame, though they can be ignored if the stream has been
+                removed from the dependency tree (see ).
+              
+              
+                If this state is reached as a result of sending a RST_STREAM frame,
+                the peer that receives the RST_STREAM might have already sent - or
+                enqueued for sending - frames on the stream that cannot be withdrawn.  An endpoint
+                MUST ignore frames that it receives on closed streams after it has sent a
+                RST_STREAM frame.  An endpoint MAY choose to limit the period over
+                which it ignores frames and treat frames that arrive after this time as being in
+                error.
+              
+              
+                Flow controlled frames (i.e., DATA) received after sending
+                RST_STREAM are counted toward the connection flow control window.
+                Even though these frames might be ignored, because they are sent before the sender
+                receives the RST_STREAM, the sender will consider the frames to count
+                against the flow control window.
+              
+              
+                An endpoint might receive a PUSH_PROMISE frame after it sends
+                RST_STREAM.  PUSH_PROMISE causes a stream to become
+                "reserved" even if the associated stream has been reset.  Therefore, a
+                RST_STREAM is needed to close an unwanted promised stream.
+              
+            
+          
+        
+        
+          In the absence of more specific guidance elsewhere in this document, implementations
+          SHOULD treat the receipt of a frame that is not expressly permitted in the description of
+          a state as a connection error of type
+          PROTOCOL_ERROR.  Frame of unknown types are ignored.

+        
    
+          
+            Streams are identified with an unsigned 31-bit integer.  Streams initiated by a client
+            MUST use odd-numbered stream identifiers; those initiated by the server MUST use
+            even-numbered stream identifiers.  A stream identifier of zero (0x0) is used for
+            connection control messages; the stream identifier zero cannot be used to establish a
+            new stream.
+          
+          
+            HTTP/1.1 requests that are upgraded to HTTP/2 (see ) are
+            responded to with a stream identifier of one (0x1).  After the upgrade
+            completes, stream 0x1 is "half closed (local)" to the client.  Therefore, stream 0x1
+            cannot be selected as a new stream identifier by a client that upgrades from HTTP/1.1.
+          
+          
+            The identifier of a newly established stream MUST be numerically greater than all
+            streams that the initiating endpoint has opened or reserved.  This governs streams that
+            are opened using a HEADERS frame and streams that are reserved using
+            PUSH_PROMISE.  An endpoint that receives an unexpected stream identifier
+            MUST respond with a connection error of
+            type PROTOCOL_ERROR.
+          
+          
+            The first use of a new stream identifier implicitly closes all streams in the "idle"
+            state that might have been initiated by that peer with a lower-valued stream identifier.
+            For example, if a client sends a HEADERS frame on stream 7 without ever
+            sending a frame on stream 5, then stream 5 transitions to the "closed" state when the
+            first frame for stream 7 is sent or received.
+          
+          
+            Stream identifiers cannot be reused.  Long-lived connections can result in an endpoint
+            exhausting the available range of stream identifiers.  A client that is unable to
+            establish a new stream identifier can establish a new connection for new streams.  A
+            server that is unable to establish a new stream identifier can send a
+            GOAWAY frame so that the client is forced to open a new connection for
+            new streams.
+          
+        
    
+
+        
    
+          
+            A peer can limit the number of concurrently active streams using the
+            SETTINGS_MAX_CONCURRENT_STREAMS parameter (see ) within a SETTINGS frame. The maximum concurrent
+            streams setting is specific to each endpoint and applies only to the peer that receives
+            the setting. That is, clients specify the maximum number of concurrent streams the
+            server can initiate, and servers specify the maximum number of concurrent streams the
+            client can initiate.
+          
+          
+            Streams that are in the "open" state, or either of the "half closed" states count toward
+            the maximum number of streams that an endpoint is permitted to open.  Streams in any of
+            these three states count toward the limit advertised in the
+            SETTINGS_MAX_CONCURRENT_STREAMS setting.  Streams in either of the
+            "reserved" states do not count toward the stream limit.
+          
+          
+            Endpoints MUST NOT exceed the limit set by their peer.  An endpoint that receives a
+            HEADERS frame that causes their advertised concurrent stream limit to be
+            exceeded MUST treat this as a stream error.  An
+            endpoint that wishes to reduce the value of
+            SETTINGS_MAX_CONCURRENT_STREAMS to a value that is below the current
+            number of open streams can either close streams that exceed the new value or allow
+            streams to complete.
+          
+        
    
+      
    
+
+     
    
+        
+          Using streams for multiplexing introduces contention over use of the TCP connection,
+          resulting in blocked streams.  A flow control scheme ensures that streams on the same
+          connection do not destructively interfere with each other.  Flow control is used for both
+          individual streams and for the connection as a whole.
+        
+        
+          HTTP/2 provides for flow control through use of the WINDOW_UPDATE frame.
+        
+
+        
    
+          
+            HTTP/2 stream flow control aims to allow a variety of flow control algorithms to be
+            used without requiring protocol changes. Flow control in HTTP/2 has the following
+            characteristics:
+            
+              
+                Flow control is specific to a connection; i.e., it is "hop-by-hop", not
+                "end-to-end".
+              
+              
+                Flow control is based on window update frames.  Receivers advertise how many octets
+                they are prepared to receive on a stream and for the entire connection.  This is a
+                credit-based scheme.
+              
+              
+                Flow control is directional with overall control provided by the receiver.  A
+                receiver MAY choose to set any window size that it desires for each stream and for
+                the entire connection.  A sender MUST respect flow control limits imposed by a
+                receiver.  Clients, servers and intermediaries all independently advertise their
+                flow control window as a receiver and abide by the flow control limits set by
+                their peer when sending.
+              
+              
+                The initial value for the flow control window is 65,535 octets for both new streams
+                and the overall connection.
+              
+              
+                The frame type determines whether flow control applies to a frame.  Of the frames
+                specified in this document, only DATA frames are subject to flow
+                control; all other frame types do not consume space in the advertised flow control
+                window.  This ensures that important control frames are not blocked by flow control.
+              
+              
+                Flow control cannot be disabled.
+              
+              
+                HTTP/2 defines only the format and semantics of the WINDOW_UPDATE
+                frame ().  This document does not stipulate how a
+                receiver decides when to send this frame or the value that it sends, nor does it
+                specify how a sender chooses to send packets.  Implementations are able to select
+                any algorithm that suits their needs.
+              
+            
+          
+          
+            Implementations are also responsible for managing how requests and responses are sent
+            based on priority; choosing how to avoid head of line blocking for requests; and
+            managing the creation of new streams.  Algorithm choices for these could interact with
+            any flow control algorithm.
+          
+        
    
+
+        
    
+          
+            Flow control is defined to protect endpoints that are operating under resource
+            constraints.  For example, a proxy needs to share memory between many connections, and
+            also might have a slow upstream connection and a fast downstream one.  Flow control
+            addresses cases where the receiver is unable process data on one stream, yet wants to
+            continue to process other streams in the same connection.
+          
+          
+            Deployments that do not require this capability can advertise a flow control window of
+            the maximum size, incrementing the available space when new data is received.  This
+            effectively disables flow control for that receiver.  Conversely, a sender is always
+            subject to the flow control window advertised by the receiver.
+          
+          
+            Deployments with constrained resources (for example, memory) can employ flow control to
+            limit the amount of memory a peer can consume.  Note, however, that this can lead to
+            suboptimal use of available network resources if flow control is enabled without
+            knowledge of the bandwidth-delay product (see ).
+          
+          
+            Even with full awareness of the current bandwidth-delay product, implementation of flow
+            control can be difficult.  When using flow control, the receiver MUST read from the TCP
+            receive buffer in a timely fashion.  Failure to do so could lead to a deadlock when
+            critical frames, such as WINDOW_UPDATE, are not read and acted upon.
+          
+        
    
+      
    
+
+      
    
+        
+          A client can assign a priority for a new stream by including prioritization information in
+          the HEADERS frame that opens the stream.  For an existing
+          stream, the PRIORITY frame can be used to change the
+          priority.
+        
+        
+          The purpose of prioritization is to allow an endpoint to express how it would prefer its
+          peer allocate resources when managing concurrent streams.  Most importantly, priority can
+          be used to select streams for transmitting frames when there is limited capacity for
+          sending.
+        
+        
+          Streams can be prioritized by marking them as dependent on the completion of other streams
+          ().  Each dependency is assigned a relative weight, a number
+          that is used to determine the relative proportion of available resources that are assigned
+          to streams dependent on the same stream.
+        
+        
+        
+          Explicitly setting the priority for a stream is input to a prioritization process.  It
+          does not guarantee any particular processing or transmission order for the stream relative
+          to any other stream.  An endpoint cannot force a peer to process concurrent streams in a
+          particular order using priority.  Expressing priority is therefore only ever a suggestion.
+        
+        
+          Providing prioritization information is optional, so default values are used if no
+          explicit indicator is provided ().
+        
+
+        
    
+          
+            Each stream can be given an explicit dependency on another stream.  Including a
+            dependency expresses a preference to allocate resources to the identified stream rather
+            than to the dependent stream.
+          
+          
+            A stream that is not dependent on any other stream is given a stream dependency of 0x0.
+            In other words, the non-existent stream 0 forms the root of the tree.
+          
+          
+            A stream that depends on another stream is a dependent stream. The stream upon which a
+            stream is dependent is a parent stream. A dependency on a stream that is not currently
+            in the tree - such as a stream in the "idle" state - results in that stream being given
+            a default priority.
+          
+          
+            When assigning a dependency on another stream, the stream is added as a new dependency
+            of the parent stream.  Dependent streams that share the same parent are not ordered with
+            respect to each other.  For example, if streams B and C are dependent on stream A, and
+            if stream D is created with a dependency on stream A, this results in a dependency order
+            of A followed by B, C, and D in any order.
+          
+          
    
+                  /|\
+  B   C             B D C
+]]>
+          
    
+          
+            An exclusive flag allows for the insertion of a new level of dependencies.  The
+            exclusive flag causes the stream to become the sole dependency of its parent stream,
+            causing other dependencies to become dependent on the exclusive stream.  In the
+            previous example, if stream D is created with an exclusive dependency on stream A, this
+            results in D becoming the dependency parent of B and C.
+          
+          
    
+                   D
+  B   C              / \
+                    B   C
+]]>
+          
    
+          
+            Inside the dependency tree, a dependent stream SHOULD only be allocated resources if all
+            of the streams that it depends on (the chain of parent streams up to 0x0) are either
+            closed, or it is not possible to make progress on them.
+          
+          
+            A stream cannot depend on itself.  An endpoint MUST treat this as a stream error of type PROTOCOL_ERROR.
+          
+        
    
+
+        
    
+          
+            All dependent streams are allocated an integer weight between 1 and 256 (inclusive).
+          
+          
+            Streams with the same parent SHOULD be allocated resources proportionally based on their
+            weight.  Thus, if stream B depends on stream A with weight 4, and C depends on stream A
+            with weight 12, and if no progress can be made on A, stream B ideally receives one third
+            of the resources allocated to stream C.
+          
+        
    
+
+        
    
+          
+            Stream priorities are changed using the PRIORITY frame.  Setting a
+            dependency causes a stream to become dependent on the identified parent stream.
+          
+          
+            Dependent streams move with their parent stream if the parent is reprioritized.  Setting
+            a dependency with the exclusive flag for a reprioritized stream moves all the
+            dependencies of the new parent stream to become dependent on the reprioritized stream.
+          
+          
+            If a stream is made dependent on one of its own dependencies, the formerly dependent
+            stream is first moved to be dependent on the reprioritized stream's previous parent.
+            The moved dependency retains its weight.
+          
+          
    
+            
+              For example, consider an original dependency tree where B and C depend on A, D and E
+              depend on C, and F depends on D.  If A is made dependent on D, then D takes the place
+              of A.  All other dependency relationships stay the same, except for F, which becomes
+              dependent on A if the reprioritization is exclusive.
+            
+              F   B   C   ==>    F   A       OR      A

+    F                                     E             E

+
+        
    
+          
+            When a stream is removed from the dependency tree, its dependencies can be moved to
+            become dependent on the parent of the closed stream.  The weights of new dependencies
+            are recalculated by distributing the weight of the dependency of the closed stream
+            proportionally based on the weights of its dependencies.
+          
+          
+            Streams that are removed from the dependency tree cause some prioritization information
+            to be lost.  Resources are shared between streams with the same parent stream, which
+            means that if a stream in that set closes or becomes blocked, any spare capacity
+            allocated to a stream is distributed to the immediate neighbors of the stream.  However,
+            if the common dependency is removed from the tree, those streams share resources with
+            streams at the next highest level.
+          
+          
+            For example, assume streams A and B share a parent, and streams C and D both depend on
+            stream A. Prior to the removal of stream A, if streams A and D are unable to proceed,
+            then stream C receives all the resources dedicated to stream A.  If stream A is removed
+            from the tree, the weight of stream A is divided between streams C and D.  If stream D
+            is still unable to proceed, this results in stream C receiving a reduced proportion of
+            resources.  For equal starting weights, C receives one third, rather than one half, of
+            available resources.
+          
+          
+            It is possible for a stream to become closed while prioritization information that
+            creates a dependency on that stream is in transit.  If a stream identified in a
+            dependency has no associated priority information, then the dependent stream is instead
+            assigned a default priority.  This potentially creates
+            suboptimal prioritization, since the stream could be given a priority that is different
+            to what is intended.
+          
+          
+            To avoid these problems, an endpoint SHOULD retain stream prioritization state for a
+            period after streams become closed.  The longer state is retained, the lower the chance
+            that streams are assigned incorrect or default priority values.
+          
+          
+            This could create a large state burden for an endpoint, so this state MAY be limited.
+            An endpoint MAY apply a fixed upper limit on the number of closed streams for which
+            prioritization state is tracked to limit state exposure.  The amount of additional state
+            an endpoint maintains could be dependent on load; under high load, prioritization state
+            can be discarded to limit resource commitments.  In extreme cases, an endpoint could
+            even discard prioritization state for active or reserved streams. If a fixed limit is
+            applied, endpoints SHOULD maintain state for at least as many streams as allowed by
+            their setting for SETTINGS_MAX_CONCURRENT_STREAMS.
+          
+          
+            An endpoint receiving a PRIORITY frame that changes the priority of a
+            closed stream SHOULD alter the dependencies of the streams that depend on it, if it has
+            retained enough state to do so.
+          
+        
    
+
+        
    
+          
+            Providing priority information is optional.  Streams are assigned a non-exclusive
+            dependency on stream 0x0 by default.  Pushed streams
+            initially depend on their associated stream.  In both cases, streams are assigned a
+            default weight of 16.
+          
+        
    
+      
    
+
+      
    
+        
+          HTTP/2 framing permits two classes of error:
+          
+            
+              An error condition that renders the entire connection unusable is a connection error.
+            
+            
+              An error in an individual stream is a stream error.
+            
+          
+        
+        
+          A list of error codes is included in .
+        
+
+        
    
+          
+            A connection error is any error which prevents further processing of the framing layer,
+            or which corrupts any connection state.
+          
+          
+            An endpoint that encounters a connection error SHOULD first send a GOAWAY
+            frame () with the stream identifier of the last stream that it
+            successfully received from its peer.  The GOAWAY frame includes an error
+            code that indicates why the connection is terminating.  After sending the
+            GOAWAY frame, the endpoint MUST close the TCP connection.
+          
+          
+            It is possible that the GOAWAY will not be reliably received by the
+            receiving endpoint (see ).  In the event of a connection error,
+            GOAWAY only provides a best effort attempt to communicate with the peer
+            about why the connection is being terminated.
+          
+          
+            An endpoint can end a connection at any time.  In particular, an endpoint MAY choose to
+            treat a stream error as a connection error.  Endpoints SHOULD send a
+            GOAWAY frame when ending a connection, providing that circumstances
+            permit it.
+          
+        
    
+
+        
    
+          
+            A stream error is an error related to a specific stream that does not affect processing
+            of other streams.
+          
+          
+            An endpoint that detects a stream error sends a RST_STREAM frame () that contains the stream identifier of the stream where the error
+            occurred.  The RST_STREAM frame includes an error code that indicates the
+            type of error.
+          
+          
+            A RST_STREAM is the last frame that an endpoint can send on a stream.
+            The peer that sends the RST_STREAM frame MUST be prepared to receive any
+            frames that were sent or enqueued for sending by the remote peer.  These frames can be
+            ignored, except where they modify connection state (such as the state maintained for
+            header compression, or flow control).
+          
+          
+            Normally, an endpoint SHOULD NOT send more than one RST_STREAM frame for
+            any stream. However, an endpoint MAY send additional RST_STREAM frames if
+            it receives frames on a closed stream after more than a round-trip time.  This behavior
+            is permitted to deal with misbehaving implementations.
+          
+          
+            An endpoint MUST NOT send a RST_STREAM in response to an
+            RST_STREAM frame, to avoid looping.
+          
+        
    
+
+        
    
+          
+            If the TCP connection is closed or reset while streams remain in open or half closed
+            states, then the endpoint MUST assume that those streams were abnormally interrupted and
+            could be incomplete.
+          
+        
    
+      
    
+
+      
    
+        
+          HTTP/2 permits extension of the protocol.  Protocol extensions can be used to provide
+          additional services or alter any aspect of the protocol, within the limitations described
+          in this section.  Extensions are effective only within the scope of a single HTTP/2
+          connection.
+        
+        
+          Extensions are permitted to use new frame types, new
+          settings, or new error
+          codes.  Registries are established for managing these extension points: frame types, settings and
+          error codes.
+        
+        
+          Implementations MUST ignore unknown or unsupported values in all extensible protocol
+          elements.  Implementations MUST discard frames that have unknown or unsupported types.
+          This means that any of these extension points can be safely used by extensions without
+          prior arrangement or negotiation.  However, extension frames that appear in the middle of
+          a header block are not permitted; these MUST be treated
+          as a connection error of type
+          PROTOCOL_ERROR.
+        
+        
+          However, extensions that could change the semantics of existing protocol components MUST
+          be negotiated before being used.  For example, an extension that changes the layout of the
+          HEADERS frame cannot be used until the peer has given a positive signal
+          that this is acceptable.  In this case, it could also be necessary to coordinate when the
+          revised layout comes into effect.  Note that treating any frame other than
+          DATA frames as flow controlled is such a change in semantics, and can only
+          be done through negotiation.
+        
+        
+          This document doesn't mandate a specific method for negotiating the use of an extension,
+          but notes that a setting could be used for that
+          purpose.  If both peers set a value that indicates willingness to use the extension, then
+          the extension can be used.  If a setting is used for extension negotiation, the initial
+          value MUST be defined so that the extension is initially disabled.
+        
+      
    
+    
    
+
+    
    
+      
+        This specification defines a number of frame types, each identified by a unique 8-bit type
+        code. Each frame type serves a distinct purpose either in the establishment and management
+        of the connection as a whole, or of individual streams.
+      
+      
+        The transmission of specific frame types can alter the state of a connection. If endpoints
+        fail to maintain a synchronized view of the connection state, successful communication
+        within the connection will no longer be possible. Therefore, it is important that endpoints
+        have a shared comprehension of how the state is affected by the use any given frame.
+      
+
+      
    
+        
+          DATA frames (type=0x0) convey arbitrary, variable-length sequences of octets associated
+          with a stream. One or more DATA frames are used, for instance, to carry HTTP request or
+          response payloads.
+        
+        
+          DATA frames MAY also contain arbitrary padding.  Padding can be added to DATA frames to
+          obscure the size of messages.
+        
+        
    
+          
+        
    
+        
+          The DATA frame contains the following fields:
+          
+            
+              An 8-bit field containing the length of the frame padding in units of octets.  This
+              field is optional and is only present if the PADDED flag is set.
+            
+            
+              Application data.  The amount of data is the remainder of the frame payload after
+              subtracting the length of the other fields that are present.
+            
+            
+              Padding octets that contain no application semantic value.  Padding octets MUST be set
+              to zero when sending and ignored when receiving.
+            
+          
+        
+
+        
+          The DATA frame defines the following flags:
+          
+            
+              Bit 1 being set indicates that this frame is the last that the endpoint will send for
+              the identified stream.  Setting this flag causes the stream to enter one of the "half closed" states or the "closed" state.
+            
+            
+              Bit 4 being set indicates that the Pad Length field and any padding that it describes
+              is present.
+            
+          
+        
+        
+          DATA frames MUST be associated with a stream. If a DATA frame is received whose stream
+          identifier field is 0x0, the recipient MUST respond with a connection error of type
+          PROTOCOL_ERROR.
+        
+        
+          DATA frames are subject to flow control and can only be sent when a stream is in the
+          "open" or "half closed (remote)" states. The entire DATA frame payload is included in flow
+          control, including Pad Length and Padding fields if present.  If a DATA frame is received
+          whose stream is not in "open" or "half closed (local)" state, the recipient MUST respond
+          with a stream error of type
+          STREAM_CLOSED.
+        
+        
+          The total number of padding octets is determined by the value of the Pad Length field. If
+          the length of the padding is greater than the length of the frame payload, the recipient
+          MUST treat this as a connection error of
+          type PROTOCOL_ERROR.
+          
+            
+              A frame can be increased in size by one octet by including a Pad Length field with a
+              value of zero.
+            
+          
+        
+        
+          Padding is a security feature; see .
+        
+      
    
+
+      
    
+        
+          The HEADERS frame (type=0x1) is used to open a stream,
+          and additionally carries a header block fragment. HEADERS frames can be sent on a stream
+          in the "open" or "half closed (remote)" states.
+        
+        
    
+          
+        
    
+        
+          The HEADERS frame payload has the following fields:
+          
+            
+              An 8-bit field containing the length of the frame padding in units of octets.  This
+              field is only present if the PADDED flag is set.
+            
+            
+              A single bit flag indicates that the stream dependency is exclusive, see .  This field is only present if the PRIORITY flag is set.
+            
+            
+              A 31-bit stream identifier for the stream that this stream depends on, see .  This field is only present if the PRIORITY flag is set.
+            
+            
+              An 8-bit weight for the stream, see .  Add one to the
+              value to obtain a weight between 1 and 256.  This field is only present if the
+              PRIORITY flag is set.
+            
+            
+              A header block fragment.
+            
+            
+              Padding octets that contain no application semantic value.  Padding octets MUST be set
+              to zero when sending and ignored when receiving.
+            
+          
+        
+
+        
+          The HEADERS frame defines the following flags:
+          
+            
+              
+                Bit 1 being set indicates that the header block is
+                the last that the endpoint will send for the identified stream.  Setting this flag
+                causes the stream to enter one of "half closed"
+                states.
+              
+              
+                A HEADERS frame carries the END_STREAM flag that signals the end of a stream.
+                However, a HEADERS frame with the END_STREAM flag set can be followed by
+                CONTINUATION frames on the same stream.  Logically, the
+                CONTINUATION frames are part of the HEADERS frame.
+              
+            
+            
+              
+                Bit 3 being set indicates that this frame contains an entire header block and is not followed by any
+                CONTINUATION frames.
+              
+              
+                A HEADERS frame without the END_HEADERS flag set MUST be followed by a
+                CONTINUATION frame for the same stream.  A receiver MUST treat the
+                receipt of any other type of frame or a frame on a different stream as a connection error of type
+                PROTOCOL_ERROR.
+              
+            
+            
+              
+                Bit 4 being set indicates that the Pad Length field and any padding that it
+                describes is present.
+              
+            
+            
+              
+                Bit 6 being set indicates that the Exclusive Flag (E), Stream Dependency, and Weight
+                fields are present; see .
+              
+            
+          
+        
+
+        
+          The payload of a HEADERS frame contains a header block
+          fragment.  A header block that does not fit within a HEADERS frame is continued in
+          a CONTINUATION frame.
+        
+
+        
+          HEADERS frames MUST be associated with a stream. If a HEADERS frame is received whose
+          stream identifier field is 0x0, the recipient MUST respond with a connection error of type
+          PROTOCOL_ERROR.
+        
+
+        
+          The HEADERS frame changes the connection state as described in .
+        
+
+        
+          The HEADERS frame includes optional padding.  Padding fields and flags are identical to
+          those defined for DATA frames.
+        
+        
+          Prioritization information in a HEADERS frame is logically equivalent to a separate
+          PRIORITY frame, but inclusion in HEADERS avoids the potential for churn in
+          stream prioritization when new streams are created.  Priorization fields in HEADERS frames
+          subsequent to the first on a stream reprioritize the
+          stream.
+        
+      
    
+
+      
    
+        
+          The PRIORITY frame (type=0x2) specifies the sender-advised
+          priority of a stream.  It can be sent at any time for an existing stream, including
+          closed streams.  This enables reprioritization of existing streams.
+        
+        
    
+          
+        
    
+        
+          The payload of a PRIORITY frame contains the following fields:
+          
+            
+              A single bit flag indicates that the stream dependency is exclusive, see .
+            
+            
+              A 31-bit stream identifier for the stream that this stream depends on, see .
+            
+            
+              An 8-bit weight for the identified stream dependency, see .  Add one to the value to obtain a weight between 1 and 256.
+            
+          
+        
+
+        
+          The PRIORITY frame does not define any flags.
+        
+
+        
+          The PRIORITY frame is associated with an existing stream. If a PRIORITY frame is received
+          with a stream identifier of 0x0, the recipient MUST respond with a connection error of type
+          PROTOCOL_ERROR.
+        
+        
+          The PRIORITY frame can be sent on a stream in any of the "reserved (remote)", "open",
+          "half closed (local)", "half closed (remote)", or "closed" states, though it cannot be
+          sent between consecutive frames that comprise a single header
+          block.  Note that this frame could arrive after processing or frame sending has
+          completed, which would cause it to have no effect on the current stream.  For a stream
+          that is in the "half closed (remote)" or "closed" - state, this frame can only affect
+          processing of the current stream and not frame transmission.
+        
+        
+          The PRIORITY frame is the only frame that can be sent for a stream in the "closed" state.
+          This allows for the reprioritization of a group of dependent streams by altering the
+          priority of a parent stream, which might be closed.  However, a PRIORITY frame sent on a
+          closed stream risks being ignored due to the peer having discarded priority state
+          information for that stream.
+        
+      
    
+
+      
    
+        
+          The RST_STREAM frame (type=0x3) allows for abnormal termination of a stream.  When sent by
+          the initiator of a stream, it indicates that they wish to cancel the stream or that an
+          error condition has occurred.  When sent by the receiver of a stream, it indicates that
+          either the receiver is rejecting the stream, requesting that the stream be cancelled, or
+          that an error condition has occurred.
+        
+        
    
+          
+        
    
+
+        
+          The RST_STREAM frame contains a single unsigned, 32-bit integer identifying the error code.  The error code indicates why the stream is being
+          terminated.
+        
+
+        
+          The RST_STREAM frame does not define any flags.
+        
+
+        
+          The RST_STREAM frame fully terminates the referenced stream and causes it to enter the
+          closed state. After receiving a RST_STREAM on a stream, the receiver MUST NOT send
+          additional frames for that stream, with the exception of PRIORITY. However,
+          after sending the RST_STREAM, the sending endpoint MUST be prepared to receive and process
+          additional frames sent on the stream that might have been sent by the peer prior to the
+          arrival of the RST_STREAM.
+        
+
+        
+          RST_STREAM frames MUST be associated with a stream.  If a RST_STREAM frame is received
+          with a stream identifier of 0x0, the recipient MUST treat this as a connection error of type
+          PROTOCOL_ERROR.
+        
+
+        
+          RST_STREAM frames MUST NOT be sent for a stream in the "idle" state.  If a RST_STREAM
+          frame identifying an idle stream is received, the recipient MUST treat this as a connection error of type
+          PROTOCOL_ERROR.
+        
+
+      
    
+
+      
    
+        
+          The SETTINGS frame (type=0x4) conveys configuration parameters that affect how endpoints
+          communicate, such as preferences and constraints on peer behavior.  The SETTINGS frame is
+          also used to acknowledge the receipt of those parameters.  Individually, a SETTINGS
+          parameter can also be referred to as a "setting".
+        
+        
+          SETTINGS parameters are not negotiated; they describe characteristics of the sending peer,
+          which are used by the receiving peer. Different values for the same parameter can be
+          advertised by each peer. For example, a client might set a high initial flow control
+          window, whereas a server might set a lower value to conserve resources.
+        
+
+        
+          A SETTINGS frame MUST be sent by both endpoints at the start of a connection, and MAY be
+          sent at any other time by either endpoint over the lifetime of the connection.
+          Implementations MUST support all of the parameters defined by this specification.
+        
+
+        
+          Each parameter in a SETTINGS frame replaces any existing value for that parameter.
+          Parameters are processed in the order in which they appear, and a receiver of a SETTINGS
+          frame does not need to maintain any state other than the current value of its
+          parameters. Therefore, the value of a SETTINGS parameter is the last value that is seen by
+          a receiver.
+        
+        
+          SETTINGS parameters are acknowledged by the receiving peer. To enable this, the SETTINGS
+          frame defines the following flag:
+          
+            
+              Bit 1 being set indicates that this frame acknowledges receipt and application of the
+              peer's SETTINGS frame.  When this bit is set, the payload of the SETTINGS frame MUST
+              be empty.  Receipt of a SETTINGS frame with the ACK flag set and a length field value
+              other than 0 MUST be treated as a connection
+              error of type FRAME_SIZE_ERROR.  For more info, see Settings Synchronization.
+            
+          
+        
+        
+          SETTINGS frames always apply to a connection, never a single stream.  The stream
+          identifier for a SETTINGS frame MUST be zero (0x0). If an endpoint receives a SETTINGS
+          frame whose stream identifier field is anything other than 0x0, the endpoint MUST respond
+          with a connection error of type
+          PROTOCOL_ERROR.
+        
+        
+          The SETTINGS frame affects connection state.  A badly formed or incomplete SETTINGS frame
+          MUST be treated as a connection error of type
+          PROTOCOL_ERROR.
+        
+
+        
    
+          
+            The payload of a SETTINGS frame consists of zero or more parameters, each consisting of
+            an unsigned 16-bit setting identifier and an unsigned 32-bit value.
+          
+
+          
    
+            
+          
    
+        
    
+
+        
    
+          
+            The following parameters are defined:
+            
+              
+                
+                  Allows the sender to inform the remote endpoint of the maximum size of the header
+                  compression table used to decode header blocks, in octets. The encoder can select
+                  any size equal to or less than this value by using signaling specific to the
+                  header compression format inside a header block. The initial value is 4,096
+                  octets.
+                
+              
+              
+                
+                  This setting can be use to disable server
+                  push. An endpoint MUST NOT send a PUSH_PROMISE frame if it
+                  receives this parameter set to a value of 0. An endpoint that has both set this
+                  parameter to 0 and had it acknowledged MUST treat the receipt of a
+                  PUSH_PROMISE frame as a connection error of type
+                  PROTOCOL_ERROR.
+                
+                
+                  The initial value is 1, which indicates that server push is permitted.  Any value
+                  other than 0 or 1 MUST be treated as a connection error of type
+                  PROTOCOL_ERROR.
+                
+              
+              
+                
+                  Indicates the maximum number of concurrent streams that the sender will allow.
+                  This limit is directional: it applies to the number of streams that the sender
+                  permits the receiver to create. Initially there is no limit to this value.  It is
+                  recommended that this value be no smaller than 100, so as to not unnecessarily
+                  limit parallelism.
+                
+                
+                  A value of 0 for SETTINGS_MAX_CONCURRENT_STREAMS SHOULD NOT be treated as special
+                  by endpoints.  A zero value does prevent the creation of new streams, however this
+                  can also happen for any limit that is exhausted with active streams.  Servers
+                  SHOULD only set a zero value for short durations; if a server does not wish to
+                  accept requests, closing the connection could be preferable.
+                
+              
+              
+                
+                  Indicates the sender's initial window size (in octets) for stream level flow
+                  control.  The initial value is 216-1 (65,535) octets.
+                
+                
+                  This setting affects the window size of all streams, including existing streams,
+                  see .
+                
+                
+                  Values above the maximum flow control window size of 231-1 MUST
+                  be treated as a connection error of
+                  type FLOW_CONTROL_ERROR.
+                
+              
+              
+                
+                  Indicates the size of the largest frame payload that the sender is willing to
+                  receive, in octets.
+                
+                
+                  The initial value is 214 (16,384) octets.  The value advertised by
+                  an endpoint MUST be between this initial value and the maximum allowed frame size
+                  (224-1 or 16,777,215 octets), inclusive.  Values outside this range
+                  MUST be treated as a connection error
+                  of type PROTOCOL_ERROR.
+                
+              
+              
+                
+                  This advisory setting informs a peer of the maximum size of header list that the
+                  sender is prepared to accept, in octets. The value is based on the uncompressed
+                  size of header fields, including the length of the name and value in octets plus
+                  an overhead of 32 octets for each header field.
+                
+                
+                  For any given request, a lower limit than what is advertised MAY be enforced.  The
+                  initial value of this setting is unlimited.
+                
+              
+            
+          
+          
+            An endpoint that receives a SETTINGS frame with any unknown or unsupported identifier
+            MUST ignore that setting.
+          
+        
    
+
+        
    
+          
+            Most values in SETTINGS benefit from or require an understanding of when the peer has
+            received and applied the changed parameter values. In order to provide
+            such synchronization timepoints, the recipient of a SETTINGS frame in which the ACK flag
+            is not set MUST apply the updated parameters as soon as possible upon receipt.
+          
+          
+            The values in the SETTINGS frame MUST be processed in the order they appear, with no
+            other frame processing between values.  Unsupported parameters MUST be ignored.  Once
+            all values have been processed, the recipient MUST immediately emit a SETTINGS frame
+            with the ACK flag set. Upon receiving a SETTINGS frame with the ACK flag set, the sender
+            of the altered parameters can rely on the setting having been applied.
+          
+          
+            If the sender of a SETTINGS frame does not receive an acknowledgement within a
+            reasonable amount of time, it MAY issue a connection error of type
+            SETTINGS_TIMEOUT.
+          
+        
    
+      
    
+
+      
    
+        
+          The PUSH_PROMISE frame (type=0x5) is used to notify the peer endpoint in advance of
+          streams the sender intends to initiate.  The PUSH_PROMISE frame includes the unsigned
+          31-bit identifier of the stream the endpoint plans to create along with a set of headers
+          that provide additional context for the stream.   contains a
+          thorough description of the use of PUSH_PROMISE frames.
+        
+
+        
    
+          
+        
    
+        
+          The PUSH_PROMISE frame payload has the following fields:
+          
+            
+              An 8-bit field containing the length of the frame padding in units of octets.  This
+              field is only present if the PADDED flag is set.
+            
+            
+              A single reserved bit.
+            
+            
+              An unsigned 31-bit integer that identifies the stream that is reserved by the
+              PUSH_PROMISE.  The promised stream identifier MUST be a valid choice for the next
+              stream sent by the sender (see new stream
+              identifier).
+            
+            
+              A header block fragment containing request header
+              fields.
+            
+            
+              Padding octets.
+            
+          
+        
+
+        
+          The PUSH_PROMISE frame defines the following flags:
+          
+            
+              
+                Bit 3 being set indicates that this frame contains an entire header block and is not followed by any
+                CONTINUATION frames.
+              
+              
+                A PUSH_PROMISE frame without the END_HEADERS flag set MUST be followed by a
+                CONTINUATION frame for the same stream.  A receiver MUST treat the receipt of any
+                other type of frame or a frame on a different stream as a connection error of type
+                PROTOCOL_ERROR.
+              
+            
+            
+              
+                Bit 4 being set indicates that the Pad Length field and any padding that it
+                describes is present.
+              
+            
+          
+        
+
+        
+          PUSH_PROMISE frames MUST be associated with an existing, peer-initiated stream. The stream
+          identifier of a PUSH_PROMISE frame indicates the stream it is associated with.  If the
+          stream identifier field specifies the value 0x0, a recipient MUST respond with a connection error of type
+          PROTOCOL_ERROR.
+        
+
+        
+          Promised streams are not required to be used in the order they are promised.  The
+          PUSH_PROMISE only reserves stream identifiers for later use.
+        
+
+        
+          PUSH_PROMISE MUST NOT be sent if the SETTINGS_ENABLE_PUSH setting of the
+          peer endpoint is set to 0.  An endpoint that has set this setting and has received
+          acknowledgement MUST treat the receipt of a PUSH_PROMISE frame as a connection error of type
+          PROTOCOL_ERROR.
+        
+        
+          Recipients of PUSH_PROMISE frames can choose to reject promised streams by returning a
+          RST_STREAM referencing the promised stream identifier back to the sender of
+          the PUSH_PROMISE.
+        
+
+       
+          A PUSH_PROMISE frame modifies the connection state in two ways.  The inclusion of a header block potentially modifies the state maintained for
+          header compression.  PUSH_PROMISE also reserves a stream for later use, causing the
+          promised stream to enter the "reserved" state.  A sender MUST NOT send a PUSH_PROMISE on a
+          stream unless that stream is either "open" or "half closed (remote)"; the sender MUST
+          ensure that the promised stream is a valid choice for a new stream identifier (that is, the promised stream MUST
+          be in the "idle" state).
+        
+        
+          Since PUSH_PROMISE reserves a stream, ignoring a PUSH_PROMISE frame causes the stream
+          state to become indeterminate.  A receiver MUST treat the receipt of a PUSH_PROMISE on a
+          stream that is neither "open" nor "half closed (local)" as a connection error of type
+          PROTOCOL_ERROR.  However, an endpoint that has sent
+          RST_STREAM on the associated stream MUST handle PUSH_PROMISE frames that
+          might have been created before the RST_STREAM frame is received and
+          processed.
+        
+        
+          A receiver MUST treat the receipt of a PUSH_PROMISE that promises an illegal stream identifier (that is, an identifier for a
+          stream that is not currently in the "idle" state) as a connection error of type
+          PROTOCOL_ERROR.
+        
+
+        
+          The PUSH_PROMISE frame includes optional padding.  Padding fields and flags are identical
+          to those defined for DATA frames.
+        
+      
    
+
+      
    
+        
+          The PING frame (type=0x6) is a mechanism for measuring a minimal round trip time from the
+          sender, as well as determining whether an idle connection is still functional.  PING
+          frames can be sent from any endpoint.
+        
+        
    
+          
+        
    
+
+        
+          In addition to the frame header, PING frames MUST contain 8 octets of data in the payload.
+          A sender can include any value it chooses and use those bytes in any fashion.
+        
+        
+          Receivers of a PING frame that does not include an ACK flag MUST send a PING frame with
+          the ACK flag set in response, with an identical payload.  PING responses SHOULD be given
+          higher priority than any other frame.
+        
+
+        
+          The PING frame defines the following flags:
+          
+            
+              Bit 1 being set indicates that this PING frame is a PING response.  An endpoint MUST
+              set this flag in PING responses.  An endpoint MUST NOT respond to PING frames
+              containing this flag.
+            
+          
+        
+        
+          PING frames are not associated with any individual stream. If a PING frame is received
+          with a stream identifier field value other than 0x0, the recipient MUST respond with a
+          connection error of type
+          PROTOCOL_ERROR.
+        
+        
+          Receipt of a PING frame with a length field value other than 8 MUST be treated as a connection error of type
+          FRAME_SIZE_ERROR.
+        
+
+      
    
+
+      
    
+        
+          The GOAWAY frame (type=0x7) informs the remote peer to stop creating streams on this
+          connection.  GOAWAY can be sent by either the client or the server.  Once sent, the sender
+          will ignore frames sent on any new streams with identifiers higher than the included last
+          stream identifier.  Receivers of a GOAWAY frame MUST NOT open additional streams on the
+          connection, although a new connection can be established for new streams.
+        
+        
+          The purpose of this frame is to allow an endpoint to gracefully stop accepting new
+          streams, while still finishing processing of previously established streams.  This enables
+          administrative actions, like server maintainance.
+        
+        
+          There is an inherent race condition between an endpoint starting new streams and the
+          remote sending a GOAWAY frame.  To deal with this case, the GOAWAY contains the stream
+          identifier of the last peer-initiated stream which was or might be processed on the
+          sending endpoint in this connection.  For instance, if the server sends a GOAWAY frame,
+          the identified stream is the highest numbered stream initiated by the client.
+        
+        
+          If the receiver of the GOAWAY has sent data on streams with a higher stream identifier
+          than what is indicated in the GOAWAY frame, those streams are not or will not be
+          processed.  The receiver of the GOAWAY frame can treat the streams as though they had
+          never been created at all, thereby allowing those streams to be retried later on a new
+          connection.
+        
+        
+          Endpoints SHOULD always send a GOAWAY frame before closing a connection so that the remote
+          can know whether a stream has been partially processed or not.  For example, if an HTTP
+          client sends a POST at the same time that a server closes a connection, the client cannot
+          know if the server started to process that POST request if the server does not send a
+          GOAWAY frame to indicate what streams it might have acted on.
+        
+        
+          An endpoint might choose to close a connection without sending GOAWAY for misbehaving
+          peers.
+        
+
+        
    
+          
+        
    
+        
+          The GOAWAY frame does not define any flags.
+        
+        
+          The GOAWAY frame applies to the connection, not a specific stream.  An endpoint MUST treat
+          a GOAWAY frame with a stream identifier other than 0x0 as a connection error of type
+          PROTOCOL_ERROR.
+        
+        
+          The last stream identifier in the GOAWAY frame contains the highest numbered stream
+          identifier for which the sender of the GOAWAY frame might have taken some action on, or
+          might yet take action on.  All streams up to and including the identified stream might
+          have been processed in some way.  The last stream identifier can be set to 0 if no streams
+          were processed.
+          
+            
+              In this context, "processed" means that some data from the stream was passed to some
+              higher layer of software that might have taken some action as a result.
+            
+          
+          If a connection terminates without a GOAWAY frame, the last stream identifier is
+          effectively the highest possible stream identifier.
+        
+        
+          On streams with lower or equal numbered identifiers that were not closed completely prior
+          to the connection being closed, re-attempting requests, transactions, or any protocol
+          activity is not possible, with the exception of idempotent actions like HTTP GET, PUT, or
+          DELETE.  Any protocol activity that uses higher numbered streams can be safely retried
+          using a new connection.
+        
+        
+          Activity on streams numbered lower or equal to the last stream identifier might still
+          complete successfully.  The sender of a GOAWAY frame might gracefully shut down a
+          connection by sending a GOAWAY frame, maintaining the connection in an open state until
+          all in-progress streams complete.
+        
+        
+          An endpoint MAY send multiple GOAWAY frames if circumstances change.  For instance, an
+          endpoint that sends GOAWAY with NO_ERROR during graceful shutdown could
+          subsequently encounter an condition that requires immediate termination of the connection.
+          The last stream identifier from the last GOAWAY frame received indicates which streams
+          could have been acted upon.  Endpoints MUST NOT increase the value they send in the last
+          stream identifier, since the peers might already have retried unprocessed requests on
+          another connection.
+        
+        
+          A client that is unable to retry requests loses all requests that are in flight when the
+          server closes the connection.  This is especially true for intermediaries that might
+          not be serving clients using HTTP/2.  A server that is attempting to gracefully shut down
+          a connection SHOULD send an initial GOAWAY frame with the last stream identifier set to
+          231-1 and a NO_ERROR code.  This signals to the client that
+          a shutdown is imminent and that no further requests can be initiated.  After waiting at
+          least one round trip time, the server can send another GOAWAY frame with an updated last
+          stream identifier.  This ensures that a connection can be cleanly shut down without losing
+          requests.
+        
+
+        
+          After sending a GOAWAY frame, the sender can discard frames for streams with identifiers
+          higher than the identified last stream.  However, any frames that alter connection state
+          cannot be completely ignored.  For instance, HEADERS,
+          PUSH_PROMISE and CONTINUATION frames MUST be minimally
+          processed to ensure the state maintained for header compression is consistent (see ); similarly DATA frames MUST be counted toward the connection flow
+          control window.  Failure to process these frames can cause flow control or header
+          compression state to become unsynchronized.
+        
+
+        
+          The GOAWAY frame also contains a 32-bit error code that
+          contains the reason for closing the connection.
+        
+        
+          Endpoints MAY append opaque data to the payload of any GOAWAY frame.  Additional debug
+          data is intended for diagnostic purposes only and carries no semantic value.  Debug
+          information could contain security- or privacy-sensitive data.  Logged or otherwise
+          persistently stored debug data MUST have adequate safeguards to prevent unauthorized
+          access.
+        
+      
    
+
+      
    
+        
+          The WINDOW_UPDATE frame (type=0x8) is used to implement flow control; see  for an overview.
+        
+        
+          Flow control operates at two levels: on each individual stream and on the entire
+          connection.
+        
+        
+          Both types of flow control are hop-by-hop; that is, only between the two endpoints.
+          Intermediaries do not forward WINDOW_UPDATE frames between dependent connections.
+          However, throttling of data transfer by any receiver can indirectly cause the propagation
+          of flow control information toward the original sender.
+        
+        
+          Flow control only applies to frames that are identified as being subject to flow control.
+          Of the frame types defined in this document, this includes only DATA frames.
+          Frames that are exempt from flow control MUST be accepted and processed, unless the
+          receiver is unable to assign resources to handling the frame.  A receiver MAY respond with
+          a stream error or connection error of type
+          FLOW_CONTROL_ERROR if it is unable to accept a frame.
+        
+        
    
+          
+        
    
+        
+          The payload of a WINDOW_UPDATE frame is one reserved bit, plus an unsigned 31-bit integer
+          indicating the number of octets that the sender can transmit in addition to the existing
+          flow control window.  The legal range for the increment to the flow control window is 1 to
+          231-1 (0x7fffffff) octets.
+        
+        
+          The WINDOW_UPDATE frame does not define any flags.
+        
+        
+          The WINDOW_UPDATE frame can be specific to a stream or to the entire connection.  In the
+          former case, the frame's stream identifier indicates the affected stream; in the latter,
+          the value "0" indicates that the entire connection is the subject of the frame.
+        
+        
+          A receiver MUST treat the receipt of a WINDOW_UPDATE frame with an flow control window
+          increment of 0 as a stream error of type
+          PROTOCOL_ERROR; errors on the connection flow control window MUST be
+          treated as a connection error.
+        
+        
+          WINDOW_UPDATE can be sent by a peer that has sent a frame bearing the END_STREAM flag.
+          This means that a receiver could receive a WINDOW_UPDATE frame on a "half closed (remote)"
+          or "closed" stream.  A receiver MUST NOT treat this as an error, see .
+        
+        
+          A receiver that receives a flow controlled frame MUST always account for its contribution
+          against the connection flow control window, unless the receiver treats this as a connection error.  This is necessary even if the
+          frame is in error.  Since the sender counts the frame toward the flow control window, if
+          the receiver does not, the flow control window at sender and receiver can become
+          different.
+        
+
+        
    
+          
+            Flow control in HTTP/2 is implemented using a window kept by each sender on every
+            stream. The flow control window is a simple integer value that indicates how many octets
+            of data the sender is permitted to transmit; as such, its size is a measure of the
+            buffering capacity of the receiver.
+          
+          
+            Two flow control windows are applicable: the stream flow control window and the
+            connection flow control window.  The sender MUST NOT send a flow controlled frame with a
+            length that exceeds the space available in either of the flow control windows advertised
+            by the receiver.  Frames with zero length with the END_STREAM flag set (that is, an
+            empty DATA frame) MAY be sent if there is no available space in either
+            flow control window.
+          
+          
+            For flow control calculations, the 9 octet frame header is not counted.
+          
+          
+            After sending a flow controlled frame, the sender reduces the space available in both
+            windows by the length of the transmitted frame.
+          
+          
+            The receiver of a frame sends a WINDOW_UPDATE frame as it consumes data and frees up
+            space in flow control windows.  Separate WINDOW_UPDATE frames are sent for the stream
+            and connection level flow control windows.
+          
+          
+            A sender that receives a WINDOW_UPDATE frame updates the corresponding window by the
+            amount specified in the frame.
+          
+          
+            A sender MUST NOT allow a flow control window to exceed 231-1 octets.
+            If a sender receives a WINDOW_UPDATE that causes a flow control window to exceed this
+            maximum it MUST terminate either the stream or the connection, as appropriate.  For
+            streams, the sender sends a RST_STREAM with the error code of
+            FLOW_CONTROL_ERROR code; for the connection, a GOAWAY
+            frame with a FLOW_CONTROL_ERROR code.
+          
+          
+            Flow controlled frames from the sender and WINDOW_UPDATE frames from the receiver are
+            completely asynchronous with respect to each other. This property allows a receiver to
+            aggressively update the window size kept by the sender to prevent streams from stalling.
+          
+        
    
+
+        
    
+          
+            When an HTTP/2 connection is first established, new streams are created with an initial
+            flow control window size of 65,535 octets. The connection flow control window is 65,535
+            octets. Both endpoints can adjust the initial window size for new streams by including
+            a value for SETTINGS_INITIAL_WINDOW_SIZE in the SETTINGS
+            frame that forms part of the connection preface. The connection flow control window can
+            only be changed using WINDOW_UPDATE frames.
+          
+          
+            Prior to receiving a SETTINGS frame that sets a value for
+            SETTINGS_INITIAL_WINDOW_SIZE, an endpoint can only use the default
+            initial window size when sending flow controlled frames.  Similarly, the connection flow
+            control window is set to the default initial window size until a WINDOW_UPDATE frame is
+            received.
+          
+          
+            A SETTINGS frame can alter the initial flow control window size for all
+            current streams. When the value of SETTINGS_INITIAL_WINDOW_SIZE changes,
+            a receiver MUST adjust the size of all stream flow control windows that it maintains by
+            the difference between the new value and the old value.
+          
+          
+            A change to SETTINGS_INITIAL_WINDOW_SIZE can cause the available space in
+            a flow control window to become negative.  A sender MUST track the negative flow control
+            window, and MUST NOT send new flow controlled frames until it receives WINDOW_UPDATE
+            frames that cause the flow control window to become positive.
+          
+          
+            For example, if the client sends 60KB immediately on connection establishment, and the
+            server sets the initial window size to be 16KB, the client will recalculate the
+            available flow control window to be -44KB on receipt of the SETTINGS
+            frame.  The client retains a negative flow control window until WINDOW_UPDATE frames
+            restore the window to being positive, after which the client can resume sending.
+          
+          
+            A SETTINGS frame cannot alter the connection flow control window.
+          
+          
+            An endpoint MUST treat a change to SETTINGS_INITIAL_WINDOW_SIZE that
+            causes any flow control window to exceed the maximum size as a connection error of type
+            FLOW_CONTROL_ERROR.
+          
+        
    
+
+        
    
+          
+            A receiver that wishes to use a smaller flow control window than the current size can
+            send a new SETTINGS frame.  However, the receiver MUST be prepared to
+            receive data that exceeds this window size, since the sender might send data that
+            exceeds the lower limit prior to processing the SETTINGS frame.
+          
+          
+            After sending a SETTINGS frame that reduces the initial flow control window size, a
+            receiver has two options for handling streams that exceed flow control limits:
+            
+              
+                The receiver can immediately send RST_STREAM with
+                FLOW_CONTROL_ERROR error code for the affected streams.
+              
+              
+                The receiver can accept the streams and tolerate the resulting head of line
+                blocking, sending WINDOW_UPDATE frames as it consumes data.
+              
+            
+          
+        
    
+      
    
+
+      
    
+        
+          The CONTINUATION frame (type=0x9) is used to continue a sequence of header block fragments.  Any number of CONTINUATION frames can
+          be sent on an existing stream, as long as the preceding frame is on the same stream and is
+          a HEADERS, PUSH_PROMISE or CONTINUATION frame without the
+          END_HEADERS flag set.
+        
+
+        
    
+          
+        
    
+        
+          The CONTINUATION frame payload contains a header block
+          fragment.
+        
+
+        
+          The CONTINUATION frame defines the following flag:
+          
+            
+              
+                Bit 3 being set indicates that this frame ends a header
+                block.
+              
+              
+                If the END_HEADERS bit is not set, this frame MUST be followed by another
+                CONTINUATION frame.  A receiver MUST treat the receipt of any other type of frame or
+                a frame on a different stream as a connection
+                error of type PROTOCOL_ERROR.
+              
+            
+          
+        
+
+        
+          The CONTINUATION frame changes the connection state as defined in .
+        
+
+        
+          CONTINUATION frames MUST be associated with a stream. If a CONTINUATION frame is received
+          whose stream identifier field is 0x0, the recipient MUST respond with a connection error of type PROTOCOL_ERROR.
+        
+
+        
+          A CONTINUATION frame MUST be preceded by a HEADERS,
+          PUSH_PROMISE or CONTINUATION frame without the END_HEADERS flag set.  A
+          recipient that observes violation of this rule MUST respond with a  connection error of type
+          PROTOCOL_ERROR.

+        Error codes are 32-bit fields that are used in RST_STREAM and
+        GOAWAY frames to convey the reasons for the stream or connection error.
+      
+
+      
+        Error codes share a common code space.  Some error codes apply only to either streams or the
+        entire connection and have no defined semantics in the other context.
+      
+
+      
+        The following error codes are defined:
+        
+          
+            The associated condition is not as a result of an error.  For example, a
+            GOAWAY might include this code to indicate graceful shutdown of a
+            connection.
+          
+          
+            The endpoint detected an unspecific protocol error.  This error is for use when a more
+            specific error code is not available.
+          
+          
+            The endpoint encountered an unexpected internal error.
+          
+          
+            The endpoint detected that its peer violated the flow control protocol.
+          
+          
+            The endpoint sent a SETTINGS frame, but did not receive a response in a
+            timely manner.  See Settings Synchronization.
+          
+          
+            The endpoint received a frame after a stream was half closed.
+          
+          
+            The endpoint received a frame with an invalid size.
+          
+          
+            The endpoint refuses the stream prior to performing any application processing, see
+             for details.
+          
+          
+            Used by the endpoint to indicate that the stream is no longer needed.
+          
+          
+            The endpoint is unable to maintain the header compression context for the connection.
+          
+          
+            The connection established in response to a CONNECT
+            request was reset or abnormally closed.
+          
+          
+            The endpoint detected that its peer is exhibiting a behavior that might be generating
+            excessive load.
+          
+          
+            The underlying transport has properties that do not meet minimum security
+            requirements (see ).
+          
+        
+      
+      
+        Unknown or unsupported error codes MUST NOT trigger any special behavior.  These MAY be
+        treated by an implementation as being equivalent to INTERNAL_ERROR.

+      
+        HTTP/2 is intended to be as compatible as possible with current uses of HTTP. This means
+        that, from the application perspective, the features of the protocol are largely
+        unchanged. To achieve this, all request and response semantics are preserved, although the
+        syntax of conveying those semantics has changed.
+      
+      
+        Thus, the specification and requirements of HTTP/1.1 Semantics and Content , Conditional Requests , Range Requests , Caching  and Authentication  are applicable to HTTP/2. Selected portions of HTTP/1.1 Message Syntax
+        and Routing , such as the HTTP and HTTPS URI schemes, are also
+        applicable in HTTP/2, but the expression of those semantics for this protocol are defined
+        in the sections below.
+      
+
+      
    
+        
+          A client sends an HTTP request on a new stream, using a previously unused stream identifier.  A server sends an HTTP response on
+          the same stream as the request.
+        
+        
+          An HTTP message (request or response) consists of:
+          
+            
+              for a response only, zero or more HEADERS frames (each followed by zero
+              or more CONTINUATION frames) containing the message headers of
+              informational (1xx) HTTP responses (see  and ),
+              and
+            
+            
+              one HEADERS frame (followed by zero or more CONTINUATION
+              frames) containing the message headers (see ), and
+            
+            
+              zero or more DATA frames containing the message payload (see ), and
+            
+            
+              optionally, one HEADERS frame, followed by zero or more
+              CONTINUATION frames containing the trailer-part, if present (see ).
+            
+          
+          The last frame in the sequence bears an END_STREAM flag, noting that a
+          HEADERS frame bearing the END_STREAM flag can be followed by
+          CONTINUATION frames that carry any remaining portions of the header block.
+        
+        
+          Other frames (from any stream) MUST NOT occur between either HEADERS frame
+          and any CONTINUATION frames that might follow.
+        
+
+        
+          Trailing header fields are carried in a header block that also terminates the stream.
+          That is, a sequence starting with a HEADERS frame, followed by zero or more
+          CONTINUATION frames, where the HEADERS frame bears an
+          END_STREAM flag.  Header blocks after the first that do not terminate the stream are not
+          part of an HTTP request or response.
+        
+        
+          A HEADERS frame (and associated CONTINUATION frames) can
+          only appear at the start or end of a stream.  An endpoint that receives a
+          HEADERS frame without the END_STREAM flag set after receiving a final
+          (non-informational) status code MUST treat the corresponding request or response as malformed.
+        
+
+        
+          An HTTP request/response exchange fully consumes a single stream.  A request starts with
+          the HEADERS frame that puts the stream into an "open" state. The request
+          ends with a frame bearing END_STREAM, which causes the stream to become "half closed
+          (local)" for the client and "half closed (remote)" for the server.  A response starts with
+          a HEADERS frame and ends with a frame bearing END_STREAM, which places the
+          stream in the "closed" state.
+          
+        
+
+        
    
+          
+            HTTP/2 removes support for the 101 (Switching Protocols) informational status code
+            ().
+          
+          
+            The semantics of 101 (Switching Protocols) aren't applicable to a multiplexed protocol.
+            Alternative protocols are able to use the same mechanisms that HTTP/2 uses to negotiate
+            their use (see ).
+          
+        
    
+
+        
    
+          
+            HTTP header fields carry information as a series of key-value pairs. For a listing of
+            registered HTTP headers, see the Message Header Field Registry maintained at .
+          
+
+          
    
+            
+              While HTTP/1.x used the message start-line (see ) to convey the target URI and method of the request, and the
+              status code for the response, HTTP/2 uses special pseudo-header fields beginning with
+              ':' character (ASCII 0x3a) for this purpose.
+            
+            
+              Pseudo-header fields are not HTTP header fields. Endpoints MUST NOT generate
+              pseudo-header fields other than those defined in this document.
+            
+            
+              Pseudo-header fields are only valid in the context in which they are defined.
+              Pseudo-header fields defined for requests MUST NOT appear in responses; pseudo-header
+              fields defined for responses MUST NOT appear in requests.  Pseudo-header fields MUST
+              NOT appear in trailers.  Endpoints MUST treat a request or response that contains
+              undefined or invalid pseudo-header fields as malformed.
+            
+            
+              Just as in HTTP/1.x, header field names are strings of ASCII characters that are
+              compared in a case-insensitive fashion. However, header field names MUST be converted
+              to lowercase prior to their encoding in HTTP/2. A request or response containing
+              uppercase header field names MUST be treated as malformed.
+            
+            
+              All pseudo-header fields MUST appear in the header block before regular header fields.
+              Any request or response that contains a pseudo-header field that appears in a header
+              block after a regular header field MUST be treated as malformed.
+            
+          
    
+
+          
    
+            
+              HTTP/2 does not use the Connection header field to
+              indicate connection-specific header fields; in this protocol, connection-specific
+              metadata is conveyed by other means.  An endpoint MUST NOT generate a HTTP/2 message
+              containing connection-specific header fields; any message containing
+              connection-specific header fields MUST be treated as malformed.
+            
+            
+              This means that an intermediary transforming an HTTP/1.x message to HTTP/2 will need
+              to remove any header fields nominated by the Connection header field, along with the
+              Connection header field itself. Such intermediaries SHOULD also remove other
+              connection-specific header fields, such as Keep-Alive, Proxy-Connection,
+              Transfer-Encoding and Upgrade, even if they are not nominated by Connection.
+            
+            
+              One exception to this is the TE header field, which MAY be present in an HTTP/2
+              request, but when it is MUST NOT contain any value other than "trailers".
+            
+            
+              
+                
+                  HTTP/2 purposefully does not support upgrade to another protocol.  The handshake
+                  methods described in  are believed sufficient to
+                  negotiate the use of alternative protocols.
+                
+              
+            
+          
    
+
+          
    
+            
+              The following pseudo-header fields are defined for HTTP/2 requests:
+              
+                
+                  
+                    The :method pseudo-header field includes the HTTP
+                    method ().
+                  
+                
+                
+                  
+                    The :scheme pseudo-header field includes the scheme
+                    portion of the target URI ().
+                  
+                  
+                    :scheme is not restricted to http and https schemed URIs.  A
+                    proxy or gateway can translate requests for non-HTTP schemes, enabling the use
+                    of HTTP to interact with non-HTTP services.
+                  
+                
+                
+                  
+                    The :authority pseudo-header field includes the
+                    authority portion of the target URI (). The authority MUST NOT include the deprecated userinfo subcomponent for http
+                    or https schemed URIs.
+                  
+                  
+                    To ensure that the HTTP/1.1 request line can be reproduced accurately, this
+                    pseudo-header field MUST be omitted when translating from an HTTP/1.1 request
+                    that has a request target in origin or asterisk form (see ). Clients that generate
+                    HTTP/2 requests directly SHOULD use the :authority pseudo-header
+                    field instead of the Host header field. An
+                    intermediary that converts an HTTP/2 request to HTTP/1.1 MUST create a Host header field if one is not present in a request by
+                    copying the value of the :authority pseudo-header
+                    field.
+                  
+                
+                
+                  
+                    The :path pseudo-header field includes the path and
+                    query parts of the target URI (the path-absolute
+                    production from  and optionally a '?' character
+                    followed by the query production, see  and ). A request in asterisk form includes the value '*' for the
+                    :path pseudo-header field.
+                  
+                  
+                    This pseudo-header field MUST NOT be empty for http
+                    or https URIs; http or
+                    https URIs that do not contain a path component
+                    MUST include a value of '/'. The exception to this rule is an OPTIONS request
+                    for an http or https
+                    URI that does not include a path component; these MUST include a :path pseudo-header field with a value of '*' (see ).
+                  
+                
+              
+            
+            
+              All HTTP/2 requests MUST include exactly one valid value for the :method, :scheme, and :path pseudo-header fields, unless it is a CONNECT request. An HTTP request that omits mandatory
+              pseudo-header fields is malformed.
+            
+            
+              HTTP/2 does not define a way to carry the version identifier that is included in the
+              HTTP/1.1 request line.
+            
+          
    
+
+          
    
+            
+              For HTTP/2 responses, a single :status pseudo-header
+              field is defined that carries the HTTP status code field (see ). This pseudo-header field MUST be included in all
+              responses, otherwise the response is malformed.
+            
+            
+              HTTP/2 does not define a way to carry the version or reason phrase that is included in
+              an HTTP/1.1 status line.
+            
+          
    
+
+         
    
+            
+              The Cookie header field can carry a significant amount of
+              redundant data.
+            
+            
+              The Cookie header field uses a semi-colon (";") to delimit cookie-pairs (or "crumbs").
+              This header field doesn't follow the list construction rules in HTTP (see ), which prevents cookie-pairs from
+              being separated into different name-value pairs.  This can significantly reduce
+              compression efficiency as individual cookie-pairs are updated.
+            
+            
+              To allow for better compression efficiency, the Cookie header field MAY be split into
+              separate header fields, each with one or more cookie-pairs.  If there are multiple
+              Cookie header fields after decompression, these MUST be concatenated into a single
+              octet string using the two octet delimiter of 0x3B, 0x20 (the ASCII string "; ")
+              before being passed into a non-HTTP/2 context, such as an HTTP/1.1 connection, or a
+              generic HTTP server application.
+            
+            
    
+              
+                Therefore, the following two lists of Cookie header fields are semantically
+                equivalent.
+              
+              
+            
    
+          
    
+
+          
    
+            
+              A malformed request or response is one that is an otherwise valid sequence of HTTP/2
+              frames, but is otherwise invalid due to the presence of extraneous frames, prohibited
+              header fields, the absence of mandatory header fields, or the inclusion of uppercase
+              header field names.
+            
+            
+              A request or response that includes an entity body can include a content-length header field.  A request or response is also
+              malformed if the value of a content-length header field
+              does not equal the sum of the DATA frame payload lengths that form the
+              body.  A response that is defined to have no payload, as described in , can have a non-zero
+              content-length header field, even though no content is
+              included in DATA frames.
+            
+            
+              Intermediaries that process HTTP requests or responses (i.e., any intermediary not
+              acting as a tunnel) MUST NOT forward a malformed request or response.  Malformed
+              requests or responses that are detected MUST be treated as a stream error of type PROTOCOL_ERROR.
+            
+            
+              For malformed requests, a server MAY send an HTTP response prior to closing or
+              resetting the stream.  Clients MUST NOT accept a malformed response. Note that these
+              requirements are intended to protect against several types of common attacks against
+              HTTP; they are deliberately strict, because being permissive can expose
+              implementations to these vulnerabilities.
+

+            This section shows HTTP/1.1 requests and responses, with illustrations of equivalent
+            HTTP/2 requests and responses.
+          
+          
+            An HTTP GET request includes request header fields and no body and is therefore
+            transmitted as a single HEADERS frame, followed by zero or more
+            CONTINUATION frames containing the serialized block of request header
+            fields.  The HEADERS frame in the following has both the END_HEADERS and
+            END_STREAM flags set; no CONTINUATION frames are sent:
+          
+
+          
    
+                 + END_STREAM
+  Accept: image/jpeg                 + END_HEADERS
+                                       :method = GET

+          
+            In HTTP/1.1, an HTTP client is unable to retry a non-idempotent request when an error
+            occurs, because there is no means to determine the nature of the error.  It is possible
+            that some server processing occurred prior to the error, which could result in
+            undesirable effects if the request were reattempted.
+          
+          
+            HTTP/2 provides two mechanisms for providing a guarantee to a client that a request has
+            not been processed:
+            
+              
+                The GOAWAY frame indicates the highest stream number that might have
+                been processed.  Requests on streams with higher numbers are therefore guaranteed to
+                be safe to retry.
+              
+              
+                The REFUSED_STREAM error code can be included in a
+                RST_STREAM frame to indicate that the stream is being closed prior to
+                any processing having occurred.  Any request that was sent on the reset stream can
+                be safely retried.
+              
+            
+          
+          
+            Requests that have not been processed have not failed; clients MAY automatically retry
+            them, even those with non-idempotent methods.
+          
+          
+            A server MUST NOT indicate that a stream has not been processed unless it can guarantee
+            that fact.  If frames that are on a stream are passed to the application layer for any
+            stream, then REFUSED_STREAM MUST NOT be used for that stream, and a
+            GOAWAY frame MUST include a stream identifier that is greater than or
+            equal to the given stream identifier.
+          
+          
+            In addition to these mechanisms, the PING frame provides a way for a
+            client to easily test a connection.  Connections that remain idle can become broken as
+            some middleboxes (for instance, network address translators, or load balancers) silently
+            discard connection bindings.  The PING frame allows a client to safely
+            test whether a connection is still active without sending a request.
+          
+        
    
+      
    
+
+      
    
+        
+          HTTP/2 allows a server to pre-emptively send (or "push") responses (along with
+          corresponding "promised" requests) to a client in association with a previous
+          client-initiated request. This can be useful when the server knows the client will need
+          to have those responses available in order to fully process the response to the original
+          request.
+        
+
+        
+          Pushing additional message exchanges in this fashion is optional, and is negotiated
+          between individual endpoints. The SETTINGS_ENABLE_PUSH setting can be set
+          to 0 to indicate that server push is disabled.
+        
+        
+          Promised requests MUST be cacheable (see ), MUST be safe (see ) and MUST NOT include a request body. Clients that receive a
+          promised request that is not cacheable, unsafe or that includes a request body MUST
+          reset the stream with a stream error of type
+          PROTOCOL_ERROR.
+        
+        
+          Pushed responses that are cacheable (see ) can be stored by the client, if it implements a HTTP
+          cache.  Pushed responses are considered successfully validated on the origin server (e.g.,
+          if the "no-cache" cache response directive  is present) while the stream identified by the
+          promised stream ID is still open.
+        
+        
+          Pushed responses that are not cacheable MUST NOT be stored by any HTTP cache. They MAY
+          be made available to the application separately.
+        
+        
+          An intermediary can receive pushes from the server and choose not to forward them on to
+          the client. In other words, how to make use of the pushed information is up to that
+          intermediary. Equally, the intermediary might choose to make additional pushes to the
+          client, without any action taken by the server.
+        
+        
+          A client cannot push. Thus, servers MUST treat the receipt of a
+          PUSH_PROMISE frame as a connection
+          error of type PROTOCOL_ERROR. Clients MUST reject any attempt to
+          change the SETTINGS_ENABLE_PUSH setting to a value other than 0 by treating
+          the message as a connection error of type
+          PROTOCOL_ERROR.
+        
+
+        
    
+          
+            Server push is semantically equivalent to a server responding to a request; however, in
+            this case that request is also sent by the server, as a PUSH_PROMISE
+            frame.
+          
+          
+            The PUSH_PROMISE frame includes a header block that contains a complete
+            set of request header fields that the server attributes to the request. It is not
+            possible to push a response to a request that includes a request body.
+          
+
+          
+            Pushed responses are always associated with an explicit request from the client. The
+            PUSH_PROMISE frames sent by the server are sent on that explicit
+            request's stream. The PUSH_PROMISE frame also includes a promised stream
+            identifier, chosen from the stream identifiers available to the server (see ).
+          
+
+          
+            The header fields in PUSH_PROMISE and any subsequent
+            CONTINUATION frames MUST be a valid and complete set of request header fields.  The server MUST include a method in
+            the :method header field that is safe and cacheable.  If a
+            client receives a PUSH_PROMISE that does not include a complete and valid
+            set of header fields, or the :method header field identifies
+            a method that is not safe, it MUST respond with a stream error of type PROTOCOL_ERROR.
+          
+
+          
+            The server SHOULD send PUSH_PROMISE ()
+            frames prior to sending any frames that reference the promised responses. This avoids a
+            race where clients issue requests prior to receiving any PUSH_PROMISE
+            frames.
+          
+          
+            For example, if the server receives a request for a document containing embedded links
+            to multiple image files, and the server chooses to push those additional images to the
+            client, sending push promises before the DATA frames that contain the
+            image links ensures that the client is able to see the promises before discovering
+            embedded links. Similarly, if the server pushes responses referenced by the header block
+            (for instance, in Link header fields), sending the push promises before sending the
+            header block ensures that clients do not request them.
+          
+
+          
+            PUSH_PROMISE frames MUST NOT be sent by the client.
+          
+          
+            PUSH_PROMISE frames can be sent by the server in response to any
+            client-initiated stream, but the stream MUST be in either the "open" or "half closed
+            (remote)" state with respect to the server.  PUSH_PROMISE frames are
+            interspersed with the frames that comprise a response, though they cannot be
+            interspersed with HEADERS and CONTINUATION frames that
+            comprise a single header block.
+          
+          
+            Sending a PUSH_PROMISE frame creates a new stream and puts the stream
+            into the “reserved (local)” state for the server and the “reserved (remote)” state for
+            the client.
+          
+        
    
+
+        
    
+          
+            After sending the PUSH_PROMISE frame, the server can begin delivering the
+            pushed response as a response on a server-initiated
+            stream that uses the promised stream identifier.  The server uses this stream to
+            transmit an HTTP response, using the same sequence of frames as defined in .  This stream becomes "half closed"
+            to the client after the initial HEADERS frame is sent.
+          
+
+          
+            Once a client receives a PUSH_PROMISE frame and chooses to accept the
+            pushed response, the client SHOULD NOT issue any requests for the promised response
+            until after the promised stream has closed.
+          
+
+          
+            If the client determines, for any reason, that it does not wish to receive the pushed
+            response from the server, or if the server takes too long to begin sending the promised
+            response, the client can send an RST_STREAM frame, using either the
+            CANCEL or REFUSED_STREAM codes, and referencing the pushed
+            stream's identifier.
+          
+          
+            A client can use the SETTINGS_MAX_CONCURRENT_STREAMS setting to limit the
+            number of responses that can be concurrently pushed by a server.  Advertising a
+            SETTINGS_MAX_CONCURRENT_STREAMS value of zero disables server push by
+            preventing the server from creating the necessary streams.  This does not prohibit a
+            server from sending PUSH_PROMISE frames; clients need to reset any
+            promised streams that are not wanted.
+          
+
+          
+            Clients receiving a pushed response MUST validate that either the server is
+            authoritative (see ), or the proxy that provided the pushed
+            response is configured for the corresponding request. For example, a server that offers
+            a certificate for only the example.com DNS-ID or Common Name
+            is not permitted to push a response for https://www.example.org/doc.
+          
+          
+            The response for a PUSH_PROMISE stream begins with a
+            HEADERS frame, which immediately puts the stream into the “half closed
+            (remote)” state for the server and “half closed (local)” state for the client, and ends
+            with a frame bearing END_STREAM, which places the stream in the "closed" state.
+            
+              
+                The client never sends a frame with the END_STREAM flag for a server push.
+              
+            
+          
+

+      
    
+
+      
    
+        
+          In HTTP/1.x, the pseudo-method CONNECT () is used to convert an HTTP connection into a tunnel to a remote host.
+          CONNECT is primarily used with HTTP proxies to establish a TLS session with an origin
+          server for the purposes of interacting with https resources.
+        
+        
+          In HTTP/2, the CONNECT method is used to establish a tunnel over a single HTTP/2 stream to
+          a remote host, for similar purposes. The HTTP header field mapping works as defined in
+          Request Header Fields, with a few
+          differences. Specifically:
+          
+            
+              The :method header field is set to CONNECT.
+            
+            
+              The :scheme and :path header
+              fields MUST be omitted.
+            
+            
+              The :authority header field contains the host and port to
+              connect to (equivalent to the authority-form of the request-target of CONNECT
+              requests, see ).
+            
+          
+        
+        
+          A proxy that supports CONNECT establishes a TCP connection to
+          the server identified in the :authority header field. Once
+          this connection is successfully established, the proxy sends a HEADERS
+          frame containing a 2xx series status code to the client, as defined in .
+        
+        
+          After the initial HEADERS frame sent by each peer, all subsequent
+          DATA frames correspond to data sent on the TCP connection.  The payload of
+          any DATA frames sent by the client is transmitted by the proxy to the TCP
+          server; data received from the TCP server is assembled into DATA frames by
+          the proxy.  Frame types other than DATA or stream management frames
+          (RST_STREAM, WINDOW_UPDATE, and PRIORITY)
+          MUST NOT be sent on a connected stream, and MUST be treated as a stream error if received.
+        
+        
+          The TCP connection can be closed by either peer.  The END_STREAM flag on a
+          DATA frame is treated as being equivalent to the TCP FIN bit.  A client is
+          expected to send a DATA frame with the END_STREAM flag set after receiving
+          a frame bearing the END_STREAM flag.  A proxy that receives a DATA frame
+          with the END_STREAM flag set sends the attached data with the FIN bit set on the last TCP
+          segment.  A proxy that receives a TCP segment with the FIN bit set sends a
+          DATA frame with the END_STREAM flag set.  Note that the final TCP segment
+          or DATA frame could be empty.
+        
+        
+          A TCP connection error is signaled with RST_STREAM.  A proxy treats any
+          error in the TCP connection, which includes receiving a TCP segment with the RST bit set,
+          as a stream error of type
+          CONNECT_ERROR.  Correspondingly, a proxy MUST send a TCP segment with the
+          RST bit set if it detects an error with the stream or the HTTP/2 connection.
+        
+

+    
    
+      
+        This section outlines attributes of the HTTP protocol that improve interoperability, reduce
+        exposure to known security vulnerabilities, or reduce the potential for implementation
+        variation.
+      
+
+      
    
+        
+          HTTP/2 connections are persistent.  For best performance, it is expected clients will not
+          close connections until it is determined that no further communication with a server is
+          necessary (for example, when a user navigates away from a particular web page), or until
+          the server closes the connection.
+        
+        
+          Clients SHOULD NOT open more than one HTTP/2 connection to a given host and port pair,
+          where host is derived from a URI, a selected alternative
+          service, or a configured proxy.
+        
+        
+          A client can create additional connections as replacements, either to replace connections
+          that are near to exhausting the available stream
+          identifier space, to refresh the keying material for a TLS connection, or to
+          replace connections that have encountered errors.
+        
+        
+          A client MAY open multiple connections to the same IP address and TCP port using different
+          Server Name Indication values or to provide different TLS
+          client certificates, but SHOULD avoid creating multiple connections with the same
+          configuration.
+        
+        
+          Servers are encouraged to maintain open connections for as long as possible, but are
+          permitted to terminate idle connections if necessary.  When either endpoint chooses to
+          close the transport-layer TCP connection, the terminating endpoint SHOULD first send a
+          GOAWAY () frame so that both endpoints can reliably
+          determine whether previously sent frames have been processed and gracefully complete or
+          terminate any necessary remaining tasks.
+        
+
+        
    
+          
+            Connections that are made to an origin servers, either directly or through a tunnel
+            created using the CONNECT method MAY be reused for
+            requests with multiple different URI authority components.  A connection can be reused
+            as long as the origin server is authoritative.  For
+            http resources, this depends on the host having resolved to
+            the same IP address.
+          
+          
+            For https resources, connection reuse additionally depends
+            on having a certificate that is valid for the host in the URI.  An origin server might
+            offer a certificate with multiple subjectAltName attributes,
+            or names with wildcards, one of which is valid for the authority in the URI.  For
+            example, a certificate with a subjectAltName of *.example.com might permit the use of the same connection for
+            requests to URIs starting with https://a.example.com/ and
+            https://b.example.com/.
+          
+          
+            In some deployments, reusing a connection for multiple origins can result in requests
+            being directed to the wrong origin server.  For example, TLS termination might be
+            performed by a middlebox that uses the TLS Server Name Indication
+            (SNI) extension to select an origin server.  This means that it is possible
+            for clients to send confidential information to servers that might not be the intended
+            target for the request, even though the server is otherwise authoritative.
+          
+          
+            A server that does not wish clients to reuse connections can indicate that it is not
+            authoritative for a request by sending a 421 (Misdirected Request) status code in response
+            to the request (see ).
+          
+          
+            A client that is configured to use a proxy over HTTP/2 directs requests to that proxy
+            through a single connection.  That is, all requests sent via a proxy reuse the
+            connection to the proxy.
+          
+        
    
+
+        
    
+          
+            The 421 (Misdirected Request) status code indicates that the request was directed at a
+            server that is not able to produce a response.  This can be sent by a server that is not
+            configured to produce responses for the combination of scheme and authority that are
+            included in the request URI.
+          
+          
+            Clients receiving a 421 (Misdirected Request) response from a server MAY retry the
+            request - whether the request method is idempotent or not - over a different connection.
+            This is possible if a connection is reused () or if an alternative
+            service is selected ().
+          
+          
+            This status code MUST NOT be generated by proxies.
+          
+          
+            A 421 response is cacheable by default; i.e., unless otherwise indicated by the method
+            definition or explicit cache controls (see ).
+          
+        
    
+      
    
+
+      
    
+        
+          Implementations of HTTP/2 MUST support TLS 1.2 for HTTP/2 over
+          TLS.  The general TLS usage guidance in  SHOULD be followed, with
+          some additional restrictions that are specific to HTTP/2.
+        
+
+        
+          An implementation of HTTP/2 over TLS MUST use TLS 1.2 or higher with the restrictions on
+          feature set and cipher suite described in this section.  Due to implementation
+          limitations, it might not be possible to fail TLS negotiation.  An endpoint MUST
+          immediately terminate an HTTP/2 connection that does not meet these minimum requirements
+          with a connection error of type
+          INADEQUATE_SECURITY.
+        
+
+        
    
+          
+            The TLS implementation MUST support the Server Name Indication
+            (SNI) extension to TLS. HTTP/2 clients MUST indicate the target domain name when
+            negotiating TLS.
+          
+          
+            The TLS implementation MUST disable compression.  TLS compression can lead to the
+            exposure of information that would not otherwise be revealed .
+            Generic compression is unnecessary since HTTP/2 provides compression features that are
+            more aware of context and therefore likely to be more appropriate for use for
+            performance, security or other reasons.
+          
+          
+            The TLS implementation MUST disable renegotiation.  An endpoint MUST treat a TLS
+            renegotiation as a connection error of type
+            PROTOCOL_ERROR.  Note that disabling renegotiation can result in
+            long-lived connections becoming unusable due to limits on the number of messages the
+            underlying cipher suite can encipher.
+          
+          
+            A client MAY use renegotiation to provide confidentiality protection for client
+            credentials offered in the handshake, but any renegotiation MUST occur prior to sending
+            the connection preface.  A server SHOULD request a client certificate if it sees a
+            renegotiation request immediately after establishing a connection.
+          
+          
+            This effectively prevents the use of renegotiation in response to a request for a
+            specific protected resource.  A future specification might provide a way to support this
+            use case. 
+          
+        
    
+
+        
    
+          
+            The set of TLS cipher suites that are permitted in HTTP/2 is restricted.  HTTP/2 MUST
+            only be used with cipher suites that have ephemeral key exchange, such as the ephemeral Diffie-Hellman (DHE) or the elliptic curve variant (ECDHE).  Ephemeral key exchange MUST
+            have a minimum size of 2048 bits for DHE or security level of 128 bits for ECDHE.
+            Clients MUST accept DHE sizes of up to 4096 bits.  HTTP MUST NOT be used with cipher
+            suites that use stream or block ciphers.  Authenticated Encryption with Additional Data
+            (AEAD) modes, such as the Galois Counter Model (GCM) mode for
+            AES are acceptable.
+          
+          
+            The effect of these restrictions is that TLS 1.2 implementations could have
+            non-intersecting sets of available cipher suites, since these prevent the use of the
+            cipher suite that TLS 1.2 makes mandatory.  To avoid this problem, implementations of
+            HTTP/2 that use TLS 1.2 MUST support TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256  with P256 .
+          
+          
+            Clients MAY advertise support of cipher suites that are prohibited by the above
+            restrictions in order to allow for connection to servers that do not support HTTP/2.
+            This enables a fallback to protocols without these constraints without the additional
+            latency imposed by using a separate connection for fallback.
+          
+        
    
+      
    
+    
    
+
+    
    
+      
    
+        
+          HTTP/2 relies on the HTTP/1.1 definition of authority for determining whether a server is
+          authoritative in providing a given response, see .  This relies on local name resolution for the "http"
+          URI scheme, and the authenticated server identity for the "https" scheme (see ).
+        
+      
    
+
+      
    
+        
+          In a cross-protocol attack, an attacker causes a client to initiate a transaction in one
+          protocol toward a server that understands a different protocol.  An attacker might be able
+          to cause the transaction to appear as valid transaction in the second protocol.  In
+          combination with the capabilities of the web context, this can be used to interact with
+          poorly protected servers in private networks.
+        
+        
+          Completing a TLS handshake with an ALPN identifier for HTTP/2 can be considered sufficient
+          protection against cross protocol attacks.  ALPN provides a positive indication that a
+          server is willing to proceed with HTTP/2, which prevents attacks on other TLS-based
+          protocols.
+        
+        
+          The encryption in TLS makes it difficult for attackers to control the data which could be
+          used in a cross-protocol attack on a cleartext protocol.
+        
+        
+          The cleartext version of HTTP/2 has minimal protection against cross-protocol attacks.
+          The connection preface contains a string that is
+          designed to confuse HTTP/1.1 servers, but no special protection is offered for other
+          protocols.  A server that is willing to ignore parts of an HTTP/1.1 request containing an
+          Upgrade header field in addition to the client connection preface could be exposed to a
+          cross-protocol attack.
+        
+      
    
+
+      
    
+        
+          HTTP/2 header field names and values are encoded as sequences of octets with a length
+          prefix.  This enables HTTP/2 to carry any string of octets as the name or value of a
+          header field.  An intermediary that translates HTTP/2 requests or responses into HTTP/1.1
+          directly could permit the creation of corrupted HTTP/1.1 messages.  An attacker might
+          exploit this behavior to cause the intermediary to create HTTP/1.1 messages with illegal
+          header fields, extra header fields, or even new messages that are entirely falsified.
+        
+        
+          Header field names or values that contain characters not permitted by HTTP/1.1, including
+          carriage return (ASCII 0xd) or line feed (ASCII 0xa) MUST NOT be translated verbatim by an
+          intermediary, as stipulated in .
+        
+        
+          Translation from HTTP/1.x to HTTP/2 does not produce the same opportunity to an attacker.
+          Intermediaries that perform translation to HTTP/2 MUST remove any instances of the obs-fold production from header field values.
+        
+      
    
+
+      
    
+        
+          Pushed responses do not have an explicit request from the client; the request
+          is provided by the server in the PUSH_PROMISE frame.
+        
+        
+          Caching responses that are pushed is possible based on the guidance provided by the origin
+          server in the Cache-Control header field.  However, this can cause issues if a single
+          server hosts more than one tenant.  For example, a server might offer multiple users each
+          a small portion of its URI space.
+        
+        
+          Where multiple tenants share space on the same server, that server MUST ensure that
+          tenants are not able to push representations of resources that they do not have authority
+          over.  Failure to enforce this would allow a tenant to provide a representation that would
+          be served out of cache, overriding the actual representation that the authoritative tenant
+          provides.
+        
+        
+          Pushed responses for which an origin server is not authoritative (see
+          ) are never cached or used.
+        
+      
    
+
+      
    
+        
+          An HTTP/2 connection can demand a greater commitment of resources to operate than a
+          HTTP/1.1 connection.  The use of header compression and flow control depend on a
+          commitment of resources for storing a greater amount of state.  Settings for these
+          features ensure that memory commitments for these features are strictly bounded.
+        
+        
+          The number of PUSH_PROMISE frames is not constrained in the same fashion.
+          A client that accepts server push SHOULD limit the number of streams it allows to be in
+          the "reserved (remote)" state.  Excessive number of server push streams can be treated as
+          a stream error of type
+          ENHANCE_YOUR_CALM.
+        
+        
+          Processing capacity cannot be guarded as effectively as state capacity.
+        
+        
+          The SETTINGS frame can be abused to cause a peer to expend additional
+          processing time. This might be done by pointlessly changing SETTINGS parameters, setting
+          multiple undefined parameters, or changing the same setting multiple times in the same
+          frame.  WINDOW_UPDATE or PRIORITY frames can be abused to
+          cause an unnecessary waste of resources.
+        
+        
+          Large numbers of small or empty frames can be abused to cause a peer to expend time
+          processing frame headers.  Note however that some uses are entirely legitimate, such as
+          the sending of an empty DATA frame to end a stream.
+        
+        
+          Header compression also offers some opportunities to waste processing resources; see  for more details on potential abuses.
+        
+        
+          Limits in SETTINGS parameters cannot be reduced instantaneously, which
+          leaves an endpoint exposed to behavior from a peer that could exceed the new limits. In
+          particular, immediately after establishing a connection, limits set by a server are not
+          known to clients and could be exceeded without being an obvious protocol violation.
+        
+        
+          All these features - i.e., SETTINGS changes, small frames, header
+          compression - have legitimate uses.  These features become a burden only when they are
+          used unnecessarily or to excess.
+        
+        
+          An endpoint that doesn't monitor this behavior exposes itself to a risk of denial of
+          service attack.  Implementations SHOULD track the use of these features and set limits on
+          their use.  An endpoint MAY treat activity that is suspicious as a connection error of type
+          ENHANCE_YOUR_CALM.
+        
+
+        
    
+          
+            A large header block can cause an implementation to
+            commit a large amount of state.  Header fields that are critical for routing can appear
+            toward the end of a header block, which prevents streaming of header fields to their
+            ultimate destination. For this an other reasons, such as ensuring cache correctness,
+            means that an endpoint might need to buffer the entire header block.  Since there is no
+            hard limit to the size of a header block, some endpoints could be forced commit a large
+            amount of available memory for header fields.
+          
+          
+            An endpoint can use the SETTINGS_MAX_HEADER_LIST_SIZE to advise peers of
+            limits that might apply on the size of header blocks.  This setting is only advisory, so
+            endpoints MAY choose to send header blocks that exceed this limit and risk having the
+            request or response being treated as malformed.  This setting specific to a connection,
+            so any request or response could encounter a hop with a lower, unknown limit.  An
+            intermediary can attempt to avoid this problem by passing on values presented by
+            different peers, but they are not obligated to do so.
+          
+          
+            A server that receives a larger header block than it is willing to handle can send an
+            HTTP 431 (Request Header Fields Too Large) status code .  A
+            client can discard responses that it cannot process.  The header block MUST be processed
+            to ensure a consistent connection state, unless the connection is closed.
+          
+        
    
+      
    
+
+      
    
+        
+          HTTP/2 enables greater use of compression for both header fields () and entity bodies.  Compression can allow an attacker to recover
+          secret data when it is compressed in the same context as data under attacker control.
+        
+        
+          There are demonstrable attacks on compression that exploit the characteristics of the web
+          (e.g., ).  The attacker induces multiple requests containing
+          varying plaintext, observing the length of the resulting ciphertext in each, which
+          reveals a shorter length when a guess about the secret is correct.
+        
+        
+          Implementations communicating on a secure channel MUST NOT compress content that includes
+          both confidential and attacker-controlled data unless separate compression dictionaries
+          are used for each source of data.  Compression MUST NOT be used if the source of data
+          cannot be reliably determined.  Generic stream compression, such as that provided by TLS
+          MUST NOT be used with HTTP/2 ().
+        
+        
+          Further considerations regarding the compression of header fields are described in .
+        
+      
    
+
+      
    
+        
+          Padding within HTTP/2 is not intended as a replacement for general purpose padding, such
+          as might be provided by TLS.  Redundant padding could even be
+          counterproductive.  Correct application can depend on having specific knowledge of the
+          data that is being padded.
+        
+        
+          To mitigate attacks that rely on compression, disabling or limiting compression might be
+          preferable to padding as a countermeasure.
+        
+        
+          Padding can be used to obscure the exact size of frame content, and is provided to
+          mitigate specific attacks within HTTP.  For example, attacks where compressed content
+          includes both attacker-controlled plaintext and secret data (see for example, ).
+        
+        
+          Use of padding can result in less protection than might seem immediately obvious.  At
+          best, padding only makes it more difficult for an attacker to infer length information by
+          increasing the number of frames an attacker has to observe.  Incorrectly implemented
+          padding schemes can be easily defeated.  In particular, randomized padding with a
+          predictable distribution provides very little protection; similarly, padding payloads to a
+          fixed size exposes information as payload sizes cross the fixed size boundary, which could
+          be possible if an attacker can control plaintext.
+        
+        
+          Intermediaries SHOULD retain padding for DATA frames, but MAY drop padding
+          for HEADERS and PUSH_PROMISE frames.  A valid reason for an
+          intermediary to change the amount of padding of frames is to improve the protections that
+          padding provides.

+          Several characteristics of HTTP/2 provide an observer an opportunity to correlate actions
+          of a single client or server over time.  This includes the value of settings, the manner
+          in which flow control windows are managed, the way priorities are allocated to streams,
+          timing of reactions to stimulus, and handling of any optional features.
+        
+        
+          As far as this creates observable differences in behavior, they could be used as a basis
+          for fingerprinting a specific client, as defined in .

+        This document establishes a registry for frame types, settings, and error codes.  These new
+        registries are entered into a new "Hypertext Transfer Protocol (HTTP) 2 Parameters" section.
+      
+      
+        This document registers the HTTP2-Settings header field for
+        use in HTTP; and the 421 (Misdirected Request) status code.

+          This document creates two registrations for the identification of HTTP/2 in the
+          "Application Layer Protocol Negotiation (ALPN) Protocol IDs" registry established in .
+        
+        
+          The "h2" string identifies HTTP/2 when used over TLS:
+

+            0x68 0x32 ("h2")
+            This document
+          
+        
+        
+          The "h2c" string identifies HTTP/2 when used over cleartext TCP:
+          
+            HTTP/2 over TCP
+            0x68 0x32 0x63 ("h2c")

+        
+          This document establishes a registry for HTTP/2 frame type codes.  The "HTTP/2 Frame
+          Type" registry manages an 8-bit space.  The "HTTP/2 Frame Type" registry operates under
+          either of the "IETF Review" or "IESG Approval" policies for
+          values between 0x00 and 0xef, with values between 0xf0 and 0xff being reserved for
+          experimental use.
+        
+        
+          New entries in this registry require the following information:
+          
+            
+              A name or label for the frame type.
+            
+            
+              The 8-bit code assigned to the frame type.
+            
+            
+              A reference to a specification that includes a description of the frame layout,
+              it's semantics and flags that the frame type uses, including any parts of the frame
+              that are conditionally present based on the value of flags.
+            
+          
+        
+        
+          The entries in the following table are registered by this document.

+          This document establishes a registry for HTTP/2 error codes.  The "HTTP/2 Error Code"
+          registry manages a 32-bit space.  The "HTTP/2 Error Code" registry operates under the

+// nodes is the list of nodes. Each node is represented as a uint32, which
+// encodes the node's children, wildcard bit and node type (as an index into
+// the children array), ICANN bit and text.
+//
+// If the table was generated with the -comments flag, there is a //-comment
+// after each node's data. In it is the nodes-array indexes of the children,
+// formatted as (n0x1234-n0x1256), with * denoting the wildcard bit. The
+// nodeType is printed as + for normal, ! for exception, and o for parent-only
+// nodes that have children but don't match a domain label in their own right.
+// An I denotes an ICANN domain.
+//
+// The layout within the uint32, from MSB to LSB, is:
+//	[ 0 bits] unused
+//	[10 bits] children index
+//	[ 1 bits] ICANN bit
+//	[15 bits] text index
+//	[ 6 bits] text length

+Package trace implements tracing of requests and long-lived objects.
+It exports HTTP interfaces on /debug/requests and /debug/events.
+
+A trace.Trace provides tracing for short-lived objects, usually requests.
+A request handler might be implemented like this:
+
+	func fooHandler(w http.ResponseWriter, req *http.Request) {
+		tr := trace.New("mypkg.Foo", req.URL.Path)
+		defer tr.Finish()
+		...
+		tr.LazyPrintf("some event %q happened", str)
+		...
+		if err := somethingImportant(); err != nil {
+			tr.LazyPrintf("somethingImportant failed: %v", err)
+			tr.SetError()
+		}
+	}
+
+The /debug/requests HTTP endpoint organizes the traces by family,
+errors, and duration.  It also provides histogram of request duration
+for each family.
+
+A trace.EventLog provides tracing for long-lived objects, such as RPC
+connections.
+
+	// A Fetcher fetches URL paths for a single domain.
+	type Fetcher struct {
+		domain string
+		events trace.EventLog
+	}
+
+	func NewFetcher(domain string) *Fetcher {
+		return &Fetcher{
+			domain,
+			trace.NewEventLog("mypkg.Fetcher", domain),
+		}
+	}
+
+	func (f *Fetcher) Fetch(path string) (string, error) {
+		resp, err := http.Get("http://" + f.domain + "/" + path)
+		if err != nil {
+			f.events.Errorf("Get(%q) = %v", path, err)
+			return "", err
+		}
+		f.events.Printf("Get(%q) = %s", path, resp.Status)
+		...
+	}
+
+	func (f *Fetcher) Close() error {
+		f.events.Finish()
+		return nil
+	}
+
+The /debug/events HTTP endpoint organizes the event logs by family and
+by time since the last error.  The expanded view displays recent log
+entries and the log's call stack.

+// to exported (upper case) fields. Unmarshal uses a case-sensitive
+// comparison to match XML element names to tag values and struct
+// field names.
+//
+// Unmarshal maps an XML element to a struct using the following rules.
+// In the rules, the tag of a field refers to the value associated with the
+// key 'xml' in the struct field's tag (see the example above).
+//
+//   * If the struct has a field of type []byte or string with tag
+//      ",innerxml", Unmarshal accumulates the raw XML nested inside the
+//      element in that field. The rest of the rules still apply.
+//
+//   * If the struct has a field named XMLName of type xml.Name,
+//      Unmarshal records the element name in that field.
+//
+//   * If the XMLName field has an associated tag of the form
+//      "name" or "namespace-URL name", the XML element must have
+//      the given name (and, optionally, name space) or else Unmarshal
+//      returns an error.
+//
+//   * If the XML element has an attribute whose name matches a
+//      struct field name with an associated tag containing ",attr" or
+//      the explicit name in a struct field tag of the form "name,attr",
+//      Unmarshal records the attribute value in that field.
+//
+//   * If the XML element contains character data, that data is
+//      accumulated in the first struct field that has tag ",chardata".
+//      The struct field may have type []byte or string.
+//      If there is no such field, the character data is discarded.
+//
+//   * If the XML element contains comments, they are accumulated in
+//      the first struct field that has tag ",comment".  The struct
+//      field may have type []byte or string. If there is no such
+//      field, the comments are discarded.
+//
+//   * If the XML element contains a sub-element whose name matches
+//      the prefix of a tag formatted as "a" or "a>b>c", unmarshal
+//      will descend into the XML structure looking for elements with the
+//      given names, and will map the innermost elements to that struct
+//      field. A tag starting with ">" is equivalent to one starting
+//      with the field name followed by ">".
+//
+//   * If the XML element contains a sub-element whose name matches
+//      a struct field's XMLName tag and the struct field has no
+//      explicit name tag as per the previous rule, unmarshal maps
+//      the sub-element to that struct field.
+//
+//   * If the XML element contains a sub-element whose name matches a
+//      field without any mode flags (",attr", ",chardata", etc), Unmarshal
+//      maps the sub-element to that struct field.
+//
+//   * If the XML element contains a sub-element that hasn't matched any
+//      of the above rules and the struct has a field with tag ",any",
+//      unmarshal maps the sub-element to that struct field.
+//
+//   * An anonymous struct field is handled as if the fields of its
+//      value were part of the outer struct.
+//
+//   * A struct field with tag "-" is never unmarshalled into.
+//
+// Unmarshal maps an XML element to a string or []byte by saving the
+// concatenation of that element's character data in the string or
+// []byte. The saved []byte is never nil.

+// interpreting the string value in decimal. There is no check for
+// overflow.
+//

+  This fixes the buggy tab rendering that can be seen at
+http://codereview.appspot.com/116075/diff/1/2
+
+The fundamental problem was that the tab code was
+not being told what column the text began in, so it
+didn&#39;t know where to put the tab stops.  Another problem
+was that some of the code assumed that string byte
+offsets were the same as column offsets, which is only
+true if there are no tabs.
+
+In the process of fixing this, I cleaned up the arguments
+to Fold and ExpandTabs and renamed them Break and
+_ExpandTabs so that I could be sure that I found all the
+call sites.  I also wanted to verify that ExpandTabs was
+not being used from outside intra_region_diff.py.

+# Contributing to Go
+
+Go is an open source project.
+
+It is the work of hundreds of contributors. We appreciate your help!
+
+
+## Filing issues
+
+When [filing an issue](https://golang.org/issue/new), make sure to answer these five questions:
+
+1. What version of Go are you using (`go version`)?
+2. What operating system and processor architecture are you using?
+3. What did you do?
+4. What did you expect to see?
+5. What did you see instead?
+
+General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
+The gophers there will answer or ask you to file an issue if you've tripped over a bug.
+
+## Contributing code
+
+Please read the [Contribution Guidelines](https://golang.org/doc/contribute.html)
+before sending patches.
+
+**We do not accept GitHub pull requests**
+(we use [Gerrit](https://code.google.com/p/gerrit/) instead for code review).
+
+Unless otherwise noted, the Go source files are distributed under
+the BSD-style license found in the LICENSE file.

+#
+# This hand-written assembly file implements system call dispatch.

+# 	func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
+# 	func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
+#
+# The first and second are the standard ones; they differ only in

+# unlike the first two, it does not call into the scheduler to
+# let it know that a system call is running.

+# * syscall_${GOOS}.go
+#
+# This hand-written Go file implements system calls that need
+# special handling and lists "//sys" comments giving prototypes
+# for ones that can be auto-generated.  Mksyscall reads those
+# comments to generate the stubs.

+#
+# This hand-written C file includes standard C headers and then
+# creates typedef or enum names beginning with a dollar sign
+# (use of $ in variable names is a gcc extension).  The hardest
+# part about preparing this file is figuring out which headers to
+# include and which symbols need to be #defined to get the
+# actual data structures that pass through to the kernel system calls.
+# Some C libraries present alternate versions for binary compatibility
+# and translate them on the way in and out of system calls, but
+# there is almost always a #define that can get the real ones.
+# See types_darwin.c and types_linux.c for examples.

+#
+# This machine-generated file defines the system's error numbers,

+# Building `sys/unix`
+
+The sys/unix package provides access to the raw system call interface of the
+underlying operating system. See: https://godoc.org/golang.org/x/sys/unix
+
+Porting Go to a new architecture/OS combination or adding syscalls, types, or
+constants to an existing architecture/OS pair requires some manual effort;
+however, there are tools that automate much of the process.
+
+## Build Systems
+
+There are currently two ways we generate the necessary files. We are currently
+migrating the build system to use containers so the builds are reproducible.
+This is being done on an OS-by-OS basis. Please update this documentation as
+components of the build system change.
+
+### Old Build System (currently for `GOOS != "Linux" || GOARCH == "sparc64"`)
+
+The old build system generates the Go files based on the C header files
+present on your system. This means that files
+for a given GOOS/GOARCH pair must be generated on a system with that OS and
+architecture. This also means that the generated code can differ from system
+to system, based on differences in the header files.
+
+To avoid this, if you are using the old build system, only generate the Go
+files on an installation with unmodified header files. It is also important to
+keep track of which version of the OS the files were generated from (ex.
+Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes
+and have each OS upgrade correspond to a single change.
+
+To build the files for your current OS and architecture, make sure GOOS and
+GOARCH are set correctly and run `mkall.sh`. This will generate the files for
+your specific system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, perl, go
+
+### New Build System (currently for `GOOS == "Linux" && GOARCH != "sparc64"`)
+
+The new build system uses a Docker container to generate the go files directly
+from source checkouts of the kernel and various system libraries. This means
+that on any platform that supports Docker, all the files using the new build
+system can be generated at once, and generated files will not change based on
+what the person running the scripts has installed on their computer.
+
+The OS specific files for the new build system are located in the `${GOOS}`
+directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When
+the kernel or system library updates, modify the Dockerfile at
+`${GOOS}/Dockerfile` to checkout the new release of the source.
+
+To build all the files under the new build system, you must be on an amd64/Linux
+system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will
+then generate all of the files for all of the GOOS/GOARCH pairs in the new build
+system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, perl, go, docker
+
+## Component files
+
+This section describes the various files used in the code generation process.
+It also contains instructions on how to modify these files to add a new
+architecture/OS or to add additional syscalls, types, or constants. Note that
+if you are using the new build system, the scripts cannot be called normally.
+They must be called from within the docker container.
+
+### asm files
+
+The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system
+call dispatch. There are three entry points:
+```
+  func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+  func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
+  func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+```
+The first and second are the standard ones; they differ only in how many
+arguments can be passed to the kernel. The third is for low-level use by the
+ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
+let it know that a system call is running.
+
+When porting Go to an new architecture/OS, this file must be implemented for
+each GOOS/GOARCH pair.
+
+### mksysnum
+
+Mksysnum is a script located at `${GOOS}/mksysnum.pl` (or `mksysnum_${GOOS}.pl`
+for the old system). This script takes in a list of header files containing the
+syscall number declarations and parses them to produce the corresponding list of
+Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated
+constants.
+
+Adding new syscall numbers is mostly done by running the build on a sufficiently
+new installation of the target OS (or updating the source checkouts for the
+new build system). However, depending on the OS, you make need to update the
+parsing in mksysnum.
+
+### mksyscall.pl
+
+The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are
+hand-written Go files which implement system calls (for unix, the specific OS,
+or the specific OS/Architecture pair respectively) that need special handling
+and list `//sys` comments giving prototypes for ones that can be generated.
+
+The mksyscall.pl script takes the `//sys` and `//sysnb` comments and converts
+them into syscalls. This requires the name of the prototype in the comment to
+match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function
+prototype can be exported (capitalized) or not.
+
+Adding a new syscall often just requires adding a new `//sys` function prototype
+with the desired arguments and a capitalized name so it is exported. However, if
+you want the interface to the syscall to be different, often one will make an
+unexported `//sys` prototype, an then write a custom wrapper in
+`syscall_${GOOS}.go`.
+
+### types files
+
+For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or
+`types_${GOOS}.go` on the old system). This file includes standard C headers and
+creates Go type aliases to the corresponding C types. The file is then fed
+through godef to get the Go compatible definitions. Finally, the generated code
+is fed though mkpost.go to format the code correctly and remove any hidden or
+private identifiers. This cleaned-up code is written to
+`ztypes_${GOOS}_${GOARCH}.go`.
+
+The hardest part about preparing this file is figuring out which headers to
+include and which symbols need to be `#define`d to get the actual data
+structures that pass through to the kernel system calls. Some C libraries
+preset alternate versions for binary compatibility and translate them on the
+way in and out of system calls, but there is almost always a `#define` that can
+get the real ones.
+See `types_darwin.go` and `linux/types.go` for examples.
+
+To add a new type, add in the necessary include statement at the top of the
+file (if it is not already there) and add in a type alias line. Note that if
+your type is significantly different on different architectures, you may need
+some `#if/#elif` macros in your include statements.
+
+### mkerrors.sh
+
+This script is used to generate the system's various constants. This doesn't
+just include the error numbers and error strings, but also the signal numbers
+an a wide variety of miscellaneous constants. The constants come from the list
+of include files in the `includes_${uname}` variable. A regex then picks out
+the desired `#define` statements, and generates the corresponding Go constants.
+The error numbers and strings are generated from `#include `, and the
+signal numbers and strings are generated from `#include `. All of
+these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program,
+`_errors.c`, which prints out all the constants.
+
+To add a constant, add the header that includes it to the appropriate variable.
+Then, edit the regex (if necessary) to match the desired constant. Avoid making
+the regex too broad to avoid matching unintended constants.
+
+
+## Generated files
+
+### `zerror_${GOOS}_${GOARCH}.go`
+
+A file containing all of the system's generated error numbers, error strings,
+signal numbers, and constants. Generated by `mkerrors.sh` (see above).
+
+### `zsyscall_${GOOS}_${GOARCH}.go`
+
+A file containing all the generated syscalls for a specific GOOS and GOARCH.
+Generated by `mksyscall.pl` (see above).
+
+### `zsysnum_${GOOS}_${GOARCH}.go`
+
+A list of numeric constants for all the syscall number of the specific GOOS
+and GOARCH. Generated by mksysnum (see above).
+
+### `ztypes_${GOOS}_${GOARCH}.go`
+
+A file containing Go types for passing into (or returning from) syscalls.
+Generated by godefs and the types file (see above).

+// SockaddrALG enables userspace access to the Linux kernel's cryptography

+//
+// To create a file descriptor that provides access to a hash or cipher, both
+// Bind and Accept must be used. Once the setup process is complete, input
+// data can be written to the socket, processed by the kernel, and then read
+// back as hash output or ciphertext.
+//
+// Here is an example of using an AF_ALG socket with SHA1 hashing.
+// The initial socket setup process is as follows:
+//
+//      // Open a socket to perform SHA1 hashing.
+//      fd, _ := unix.Socket(unix.AF_ALG, unix.SOCK_SEQPACKET, 0)
+//      addr := &unix.SockaddrALG{Type: "hash", Name: "sha1"}
+//      unix.Bind(fd, addr)
+//      // Note: unix.Accept does not work at this time; must invoke accept()
+//      // manually using unix.Syscall.
+//      hashfd, _, _ := unix.Syscall(unix.SYS_ACCEPT, uintptr(fd), 0, 0)
+//
+// Once a file descriptor has been returned from Accept, it may be used to
+// perform SHA1 hashing. The descriptor is not safe for concurrent use, but
+// may be re-used repeatedly with subsequent Write and Read operations.
+//
+// When hashing a small byte slice or string, a single Write and Read may
+// be used:
+//
+//      // Assume hashfd is already configured using the setup process.
+//      hash := os.NewFile(hashfd, "sha1")
+//      // Hash an input string and read the results. Each Write discards
+//      // previous hash state. Read always reads the current state.
+//      b := make([]byte, 20)
+//      for i := 0; i < 2; i++ {
+//          io.WriteString(hash, "Hello, world.")
+//          hash.Read(b)
+//          fmt.Println(hex.EncodeToString(b))
+//      }
+//      // Output:

+//      // 2ae01472317d1935a84797ec1983ae243fc6aa28
+//
+// For hashing larger byte slices, or byte streams such as those read from
+// a file or socket, use Sendto with MSG_MORE to instruct the kernel to update
+// the hash digest instead of creating a new one for a given chunk and finalizing it.
+//
+//      // Assume hashfd and addr are already configured using the setup process.
+//      hash := os.NewFile(hashfd, "sha1")

+// by default, godoc will display the OS-specific documentation for the current
+// system. If you want godoc to display syscall documentation for another
+// system, set $GOOS and $GOARCH to the desired system. For example, if
+// you want to view documentation for freebsd/arm on linux/amd64, set $GOOS
+// to freebsd and $GOARCH to arm.
+// The primary use of this package is inside other packages that provide a more
+// portable interface to the system, such as "os", "time" and "net".  Use
+// those packages rather than this one if you can.
+// For details of the functions and data types in this package consult
+// the manuals for the appropriate operating system.
+// These calls return err == nil to indicate success; otherwise
+// err represents an operating system error describing the failure and
+// holds a value of type syscall.Errno.

+# Contributing to Go
+
+Go is an open source project.
+
+It is the work of hundreds of contributors. We appreciate your help!
+
+
+## Filing issues
+
+When [filing an issue](https://golang.org/issue/new), make sure to answer these five questions:
+
+1. What version of Go are you using (`go version`)?
+2. What operating system and processor architecture are you using?
+3. What did you do?
+4. What did you expect to see?
+5. What did you see instead?
+
+General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
+The gophers there will answer or ask you to file an issue if you've tripped over a bug.
+
+## Contributing code
+
+Please read the [Contribution Guidelines](https://golang.org/doc/contribute.html)
+before sending patches.
+
+**We do not accept GitHub pull requests**
+(we use [Gerrit](https://code.google.com/p/gerrit/) instead for code review).
+
+Unless otherwise noted, the Go source files are distributed under
+the BSD-style license found in the LICENSE file.

+# Go Tools
+
+This subrepository holds the source for various packages and tools that support
+the Go programming language.
+
+Some of the tools, `godoc` and `vet` for example, are included in binary Go
+distributions.
+
+Others, including the Go `guru` and the test coverage tool, can be fetched with
+`go get`.
+
+Packages include a type-checker for Go and an implementation of the
+Static Single Assignment form (SSA) representation for Go programs.
+
+## Download/Install
+
+The easiest way to install is to run `go get -u golang.org/x/tools/...`. You can
+also manually git clone the repository to `$GOPATH/src/golang.org/x/tools`.
+
+## Report Issues / Send Patches
+
+This repository uses Gerrit for code changes. To learn how to submit changes to
+this repository, see https://golang.org/doc/contribute.html.
+
+The main issue tracker for the tools repository is located at
+https://github.com/golang/go/issues. Prefix your issue with "x/tools/(your
+subdir):" in the subject line, so it is easy to find.

+The benchcmp command displays performance changes between benchmarks.
+
+Benchcmp parses the output of two 'go test' benchmark runs,
+correlates the results per benchmark, and displays the deltas.
+
+To measure the performance impact of a change, use 'go test'
+to run benchmarks before and after the change:
+
+	go test -run=NONE -bench=. ./... > old.txt
+	# make changes
+	go test -run=NONE -bench=. ./... > new.txt
+
+Then feed the benchmark results to benchcmp:
+
+	benchcmp old.txt new.txt
+
+Benchcmp will summarize and display the performance changes,
+in a format like this:
+
+	$ benchcmp old.txt new.txt
+	benchmark           old ns/op     new ns/op     delta

+// Bundle creates a single-source-file version of a source package
+// suitable for inclusion in a particular target package.
+//
+// Usage:
+//
+//	bundle [-o file] [-dst path] [-pkg name] [-prefix p] [-import old=new] 
+//
+// The src argument specifies the import path of the package to bundle.
+// The bundling of a directory of source files into a single source file
+// necessarily imposes a number of constraints.
+// The package being bundled must not use cgo; must not use conditional
+// file compilation, whether with build tags or system-specific file names
+// like code_amd64.go; must not depend on any special comments, which
+// may not be preserved; must not use any assembly sources;
+// must not use renaming imports; and must not use reflection-based APIs
+// that depend on the specific names of types or struct fields.
+//
+// By default, bundle writes the bundled code to standard output.
+// If the -o argument is given, bundle writes to the named file
+// and also includes a ``//go:generate'' comment giving the exact
+// command line used, for regenerating the file with ``go generate.''
+//
+// Bundle customizes its output for inclusion in a particular package, the destination package.
+// By default bundle assumes the destination is the package in the current directory,
+// but the destination package can be specified explicitly using the -dst option,
+// which takes an import path as its argument.
+// If the source package imports the destination package, bundle will remove
+// those imports and rewrite any references to use direct references to the
+// corresponding symbols.
+// Bundle also must write a package declaration in the output and must
+// choose a name to use in that declaration.
+// If the -package option is given, bundle uses that name.
+// Otherwise, if the -dst option is given, bundle uses the last
+// element of the destination import path.
+// Otherwise, by default bundle uses the package name found in the
+// package sources in the current directory.
+//
+// To avoid collisions, bundle inserts a prefix at the beginning of
+// every package-level const, func, type, and var identifier in src's code,
+// updating references accordingly. The default prefix is the package name
+// of the source package followed by an underscore. The -prefix option
+// specifies an alternate prefix.
+//
+// Occasionally it is necessary to rewrite imports during the bundling
+// process. The -import option, which may be repeated, specifies that
+// an import of "old" should be rewritten to import "new" instead.
+//
+// Example
+//
+// Bundle archive/zip for inclusion in cmd/dist:
+//
+//	cd $GOROOT/src/cmd/dist
+//	bundle -o zip.go archive/zip
+//
+// Bundle golang.org/x/net/http2 for inclusion in net/http,
+// prefixing all identifiers by "http2" instead of "http2_",
+// and rewriting the import "golang.org/x/net/http2/hpack"
+// to "internal/golang.org/x/net/http2/hpack":
+//
+//	cd $GOROOT/src/net/http
+//	bundle -o h2_bundle.go \
+//		-prefix http2 \
+//		-import golang.org/x/net/http2/hpack=internal/golang.org/x/net/http2/hpack \
+//		golang.org/x/net/http2
+//
+// Two ways to update the http2 bundle:
+//
+//	go generate net/http
+//
+//	cd $GOROOT/src/net/http
+//	go generate
+//
+// Update both bundles, restricting ``go generate'' to running bundle commands:
+//
+//	go generate -run bundle cmd/dist net/http

+            pta         inclusion-based Points-To Analysis
+

+           derived from them, e.g. Caller.Pkg.Pkg.Path yields the

+// Compilebench benchmarks the speed of the Go compiler.
+//
+// Usage:
+//
+//	compilebench [options]
+//
+// It times the compilation of various packages and prints results in
+// the format used by package testing (and expected by golang.org/x/perf/cmd/benchstat).
+//
+// The options are:
+//
+//	-alloc
+//		Report allocations.
+//
+//	-compile exe
+//		Use exe as the path to the cmd/compile binary.
+//
+//	-compileflags 'list'
+//		Pass the space-separated list of flags to the compilation.
+//
+//	-count n
+//		Run each benchmark n times (default 1).
+//
+//	-cpuprofile file
+//		Write a CPU profile of the compiler to file.
+//
+//	-memprofile file
+//		Write a memory profile of the compiler to file.
+//
+//	-memprofilerate rate
+//		Set runtime.MemProfileRate during compilation.
+//
+//	-obj
+//		Report object file statistics.
+//
+//  -pkg
+//		Benchmark compiling a single package.
+//
+//	-run regexp
+//		Only run benchmarks with names matching regexp.
+//
+// Although -cpuprofile and -memprofile are intended to write a
+// combined profile for all the executed benchmarks to file,
+// today they write only the profile for the last benchmark executed.
+//
+// The default memory profiling rate is one profile sample per 512 kB
+// allocated (see ``go doc runtime.MemProfileRate'').
+// Lowering the rate (for example, -memprofilerate 64000) produces
+// a more fine-grained and therefore accurate profile, but it also incurs
+// execution cost. For benchmark comparisons, never use timings
+// obtained with a low -memprofilerate option.
+//
+// Example
+//
+// Assuming the base version of the compiler has been saved with
+// ``toolstash save,'' this sequence compares the old and new compiler:
+//
+//	compilebench -count 10 -compile $(toolstash -n compile) >old.txt
+//	compilebench -count 10 >new.txt
+//	benchstat old.txt new.txt

+Cover is a program for analyzing the coverage profiles generated by
+'go test -coverprofile=cover.out'.
+
+Cover is also used by 'go test -cover' to rewrite the source code with
+annotations to track which parts of each function are executed.
+It operates on one Go source file at a time, computing approximate
+basic block information by studying the source. It is thus more portable
+than binary-rewriting coverage tools, but also a little less capable.
+For instance, it does not probe inside && and || expressions, and can
+be mildly confused by single statements with multiple function literals.
+
+For usage information, please see:
+	go help testflag
+	go tool cover -help
+
+No longer maintained:
+
+For Go releases 1.5 and later, this tool lives in the
+standard repository. The code here is not maintained.

+//
+// TODO(adonovan):

+//   a comment syntax, etc.

+const Usage = `digraph: queries over directed graphs in text form.
+
+Graph format:
+
+  Each line contains zero or more words.  Words are separated by
+  unquoted whitespace; words may contain Go-style double-quoted portions,
+  allowing spaces and other characters to be expressed.
+
+  Each field declares a node, and if there are more than one,
+  an edge from the first to each subsequent one.
+  The graph is provided on the standard input.
+
+  For instance, the following (acyclic) graph specifies a partial order
+  among the subtasks of getting dressed:
+
+	% cat clothes.txt
+	socks shoes
+	"boxer shorts" pants
+	pants belt shoes
+	shirt tie sweater
+	sweater jacket
+	hat
+
+  The line "shirt tie sweater" indicates the two edges shirt -> tie and
+  shirt -> sweater, not shirt -> tie -> sweater.
+
+Supported queries:
+
+  nodes
+	the set of all nodes
+  degree
+	the in-degree and out-degree of each node.
