We follow the standard Go style using goimports, but with a few extra
considerations.
## Linters
We use `gometalinter` to run a number of linters, the exact list can be found
in [linter.json](linter.json). Some of these are slow and expensive to run, but
a subset can be found in [linter-fast.json](linter-fast.json) that run quickly
enough to be run as part of an IDE.
We use `golangci-lint` to run a number of linters, the exact list can be found
under linters in [.golangci.yml](.golangci.yml).
[Installation](https://github.com/golangci/golangci-lint#install) and [Editor
Integration](https://github.com/golangci/golangci-lint#editor-integration) for
it can be found in the readme of golangci-lint.
For rare cases where a linter is giving a spurious warning, it can be disabled
for that line or statement using a [comment directive](https://github.com/alecthomas/gometalinter#comment-directives), e.g.
`// nolint: gocyclo`. This should be used sparingly and only when its clear
that the lint warning is spurious.

## Continuous Integration
When a Pull Request is submitted, continuous integration jobs are run
automatically to ensure the code builds and is relatively well-written. The
jobs are run on [Buildkite](https://buildkite.com/matrix-dot-org/dendrite/),
and the Buildkite pipeline configuration can be found in Matrix.org's
[pipelines repository](https://github.com/matrix-org/pipelines).

### Running CI Tests Locally
To save waiting for CI to finish after every commit, it is ideal to run the
checks locally before pushing, fixing errors first. This also saves other
people time as only so many PRs can be tested at a given time.
