This change adds python type and formatting checks and consolidates code health checks in ./tools/health-check. Dealing with relative imports in python is tricky, so we are making ./tools/impl a proper package with no directly executable files. Some of the bash shorthands in ./tools had to be converted to python for this. To make the new checks pass, we run the formatter and fix some mypy type checks. TEST=./tools/health-check BUG=b:218559722,b:219965702 Change-Id: Ie18d3d6dd2f5a033141e167a6e1aa762791941d6 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/3558592 Reviewed-by: Daniel Verkamp <dverkamp@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com> Commit-Queue: Dennis Kempin <denniskempin@google.com>

|
# Usage:
|
|
#
|
|
# To get an interactive shell for development:
|
|
# ./tools/dev_container
|
|
#
|
|
# To run a command in the container, e.g. to run presubmits:
|
|
# ./tools/dev_container ./tools/presubmit
|
|
#
|
|
# The state of the container (including build artifacts) are preserved between
|
|
# calls. To stop the container call:
|
|
# ./tools/dev_container --stop
|
|
#
|
|
# The dev container can also be called with a fresh container for each call that
|
|
# is cleaned up afterwards (e.g. when run by Kokoro):
|
|
#
|
|
# ./tools/dev_container --hermetic CMD
