Go implementation of the Hermez node.
The hermez-node
has been tested with go version 1.14
Running the unit tests requires a connection to a PostgreSQL database. You can
start PostgreSQL with docker easily this way (where yourpasswordhere
should
be your password):
POSTGRES_PASS=yourpasswordhere; sudo docker run --rm --name hermez-db-test -p 5432:5432 -e POSTGRES_DB=hermez -e POSTGRES_USER=hermez -e POSTGRES_PASSWORD="$POSTGRES_PASS" -d postgres
Afterwards, run the tests with the password as env var:
POSTGRES_PASS=yourpasswordhere go test -p 1 ./...
NOTE: -p 1
forces execution of package test in serial. Otherwise they may be
executed in paralel and the test may find unexpected entries in the SQL databse
because it's shared among all tests.
There is an extra temporary option that allows you to run the API server using the Go tests. This will be removed once the API can be properly initialized, with data from the synchronizer and so on. To use this, run:
FAKE_SERVER=yes POSTGRES_PASS=yourpasswordhere go test -timeout 0 ./api -p 1 -count 1 -v`
All Pull Requests need to pass the configured linter.
To run the linter locally, first install golangci-lint. Afterwards you can check the lints with this command:
golangci-lint run --timeout=5m -E whitespace -E gosec -E gci -E misspell -E gomnd -E gofmt -E goimports -E golint --exclude-use-default=false --max-same-issues 0
The node in mode coordinator requires a proof server (a server that is capable
of calculating proofs from the zkInputs). For testing purposes there is a mock
proof server cli at test/proofserver/cli
.
Usage of test/proofserver/cli
:
USAGE:
go run ./test/proofserver/cli OPTIONS
OPTIONS:
-a string
listen address (default "localhost:3000")
-d duration
proving time duration (default 2s)
/tmp
as tmpfsFor every processed batch, the node builds a temporary exit tree in a key-value
DB stored in /tmp
. It is highly recommended that /tmp
is mounted as a RAM
file system in production to avoid unecessary reads an writes to disk. This
can be done by mounting /tmp
as tmpfs; for example, by having this line in
/etc/fstab
:
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
