Support tools

A collection of CLI tools meant to support and automate various aspects of developing Envoy, particularly those related to code review. For example, automatic DCO signoff and pre-commit format checking.

Usage

To get started, you need only navigate to the Envoy project root and run:

./support/bootstrap

This will set up the development support toolchain automatically. The toolchain uses git hooks extensively, copying them from support/hooks to the .git folder.

The commit hook checks can be skipped using the --no-verify flags, as so:

git commit --no-verify

You can also do this by adding NO_VERIFY to .env, for example:

$ echo NO_VERIFY=1 >> .env

Or settting it in your environment:

$ export NO_VERIFY=1

Functionality

Currently the development support toolchain exposes two main pieces of functionality:

• Automatically appending DCO signoff to the end of a commit message if it doesn't exist yet. Correctly covers edge cases like commit --amend and rebase.
• Automatically running DCO and format checks on all files in the diff, before push.

Fixing Format Problems

If the pre-push format checks detect any problems, you can either fix the affected files manually or run the provided formatting script.

To run the format fix script directly:

bazel run //tools/code_format:check_format -- fix && bazel run //tools/code:check -- fix -s main -v warn

To run the format fix script under Docker:

./ci/run_envoy_docker.sh './ci/do_ci.sh format'

To run clang-tidy under Docker, run the following (this creates a full compilation db and takes a long time):

./ci/run_envoy_docker.sh ci/do_ci.sh clang_tidy
