#! /bin/bash

# Runs the linters against dendrite

# The linters can take a lot of resources and are slow, so they can be
# configured using two environment variables:
#
# - `DENDRITE_LINT_CONCURRENCY` - number of concurrent linters to run,
#   gometalinter defaults this to 8
# - `DENDRITE_LINT_DISABLE_GC` - if set then the the go gc will be disabled
#   when running the linters, speeding them up but using much more memory.

# We should move from gometalinter asap as per https://github.com/matrix-org/dendrite/issues/697 so this is a temporary
