build, pw_presubmit: Move build log saving code

Move the code that saves build logs from the pw_presubmit recipe to the
build module. Also, log the longest build steps as separate steps--the
old Milo UI (still used for led jobs) shows these as expected but the
new Milo UI shows a multi-line step_summary_text on one line.

Pigweed Recipes

This repository contains recipes for Pigweed.

A recipe is a Python script that runs a series of commands, using the recipe engine framework from the LUCI project. We use recipes to automatically check out, build, and test Pigweed and downstream projects using Pigweed in continuous integration jobs. The commands the recipes use are very similar to the ones you would use as a developer to check out, build, and test Pigweed in your local environment.

See go/pigweed-recipe-docs for complete documentation and a guide for getting started with writing recipes.

Getting the Code

The recommended way to get the source code is with git.

git clone https://pigweed.googlesource.com/infra/recipes

In most cases you will need a Chromium depot_tools checkout in your PATH as well.

git clone https://chromium.googlesource.com/chromium/tools/depot_tools ~/depot_tools
echo 'export PATH="$PATH:$HOME/depot_tools"' >> ~/.bashrc

Running Tests

./presubmit.sh runs three different sets of tests:

  • Recipe expectation tests (./recipes.py test train)
  • Formatting (./black --diff --check .)
  • Dependencies (.recipe_deps/fuchsia/scripts/cleanup_deps.py --check)

The formatting check will tell you what‘s wrong but not fix it. For that you need to run ./black .. Similarly, the dependencies check will tell you what’s wrong but you'll need to edit the files to fix issues.

If not using ./presubmit.sh you'll need to run ./scripts/ensure_black.sh before ./black is present.
