# Please use this script in conjunction with the release documentation:
# https://mozilla.github.io/ecosystem-platform/docs/fxa-engineering/release-process
#
# This script will automatically update the changelogs and bump the version
# strings for each of the "main" FxA packages in this tree. It assumes some
# uniformity in the format of the tags and changelogs, so tagging should
# always be done with this script lest that uniformity is broken.
#
# Note that this script DOES NOT PUSH TO ANY REMOTES. It is expected that a
# human will verify the results before doing that step and opening any pull
# requests.
#
# Usage:
#
# release.sh [patch]
#
# If no argument is specified, the main train number will be bumped. If the
# argument `patch` is specified, the patch number will be bumped. Any other
# argument is invalid.
#
# Steps:
#
# 1. Check the argument is valid.
# 2. Check there are no local changes.
# 3. Find the last tag.
# 4. Check there have been some commits since the last tag.
# 5. Generate the bumped version string.
# 6. If current branch is train branch, pull from origin.
# 7. Otherwise checkout existing train branch or create fresh one from master.
# 8. For each of the "main" packages...
# 8.1. List commits since the last tag.
# 8.2. For each commit...
# 8.2.1. Add the commit message to a summary string.
# 8.3. If CHANGELOG.md exists, write the summary string to CHANGELOG.md.
# 8.4. If package.json exists, update the version string in package.json.
# 8.5. If package-lock.json exists, update the version string in package-lock.json.
# 8.6. If npm-shrinkwrap.json exists, update the version string in npm-shrinkwrap.json.
# 8.7. If Cargo.toml exists, update the version string in Cargo.toml.
# 8.8. If Cargo.lock exists, update the version string in Cargo.lock.
# 9. Update the AUTHORS file
# 10. Commit changes.
# 11. Create a tag.
# 12. Tell the user what we did.
