Roll dependendencies (#103771)
Roll dependendencies

This rolls depdendencies to latest using
flutter update-packages --force-upgrade

This change includes three code changes:

* Removes charcode from the dependencies allowlist since it no longer
  appears in the transitive closure of dependencies of the flutter,
  flutter_test, flutter_driver, flutter_localizations, and
  integration_test packages.

* Uses Resolver.create instead of the deprecated Resolver constructor.
  The default Resolver constructor has been deprecated in favour of the
  static Resolver.create() factory function, which unfortunately happens
  to be async. Propagated the async-ness up the chain.
  This change was partially reverted and the deprecation ignored in this
  patch until package:coverage can be rolled internally at Google.

* Eliminates the use of the deprecated packagesPath parameter to
  HitMap.parseJson. This parameter was deprecated and replaced with
  packagePath in https://github.com/dart-lang/coverage/pull/370 which
  was part of the overall deprecation of the .packages file in Dart
  itself https://github.com/dart-lang/sdk/issues/48272. The overall goal
  being that end-user code shouldn't need to know about implementation
  details such as whether dependency information is stored in a
  .packages file or a package_info.json file, but rather use the
  package_config package to obtain the package metadata and perform
  other functions such as resolving its dependencies to filesystem
  paths. packagesPath was replaced by packagePath, which takes the path
  to the package directory itself. Internally, package:coverage then
  uses package_config to do the rest of the package/script URI
  resolution to filesystem paths.
  This change was partially reverted and the deprecation ignored in this
  patch until package:coverage can be rolled internally at Google.

This is a pre-update prior to updating flutter_template_images in
https://github.com/flutter/flutter/pull/103739

Issue: https://github.com/flutter/flutter/issues/103775
Issue: https://github.com/flutter/flutter/issues/103830

When re-applying the partially-reverted changes to code coverage,
we'll need to patch host_entrypoint.dart internally to await the Future
that we'll be returning rather than a non-async value.

Flutter Conductor

Command-line tool for managing a release of the Flutter SDK. Also see https://github.com/flutter/flutter/wiki/Release-process for more information on the release process.

Requirements

Some basic requirements to conduct a release are:

  • a Linux or macOS computer set up for Flutter development. The conductor does not support Windows.
  • git
  • Mirrors on GitHub of the Flutter framework and engine repositories.

For the best experience, it is recommended to use ssh protocol for connecting to GitHub remote repositories (i.e. for --framework-mirror and --engine-mirror specify the remote with the format git@github.com:username/reponame). If your local ssh key is password-protected, it is recommended to use ssh-agent to unlock your ssh key for the session; if you do not, each time the conductor attempts to interact with a remote, the user will be prompted to enter their ssh key password.

Usage

The main entrypoint for the conductor is bin/conductor. For brevity, the rest of this document will assume that this entrypoint is on the shell path.

All available commands can be seen via:

conductor help

Releases are initialized with the start sub-command, like:

conductor start \
  --candidate-branch=flutter-2.2-candidate.10 \
  --release-channel=beta \
  --framework-mirror=git@github.com:username/flutter.git \
  --engine-mirror=git@github.com:username/engine.git \
  --engine-cherrypicks=72114dafe28c8700f1d5d629c6ae9d34172ba395 \
  --framework-cherrypicks=a3e66b396746f6581b2b7efd1b0d0f0074215128,d8d853436206e86f416236b930e97779b143a100 \
  --dart-revision=4511eb2a779a612d9d6b2012123575013e0aef12 \

The conductor will, based on the release channel and the presence/lack of previous tags, determine which part of the release version should be incremented. In the cases where this is not correct, the version can be overridden with --version-override=3.0.0.

For more details on these command line arguments, see conductor help start. This command will write to disk a state file that will persist until the release is completed. If you already have a persistent state file, this command will fail with an error message. To see the current status of the release (at any time), issue the command:

conductor status

To delete a persistent state file (either because the release was successfully completed or abandoned), use the command:

conductor clean

Once initializing the release, the conductor tool will issue instructions for manual steps that must be executed by the user. At any time these instructions can be seen via conductor status. Once these manual steps have been completed, you can proceed to the next step by using the command:

conductor next

Steps

Once the user has finished manual steps for each step, they proceed to the next step with the command:

conductor next

Apply Engine Cherrypicks

The tool will attempt to auto-apply all engine cherrypicks. However, any cherrypicks that result in a merge conflict will be reverted and it is left to the user to manually cherry-pick them (with the command git cherry-pick $REVISION) and resolve the merge conflict in their checkout.

Once a PR is opened, the user must validate CI builds. If there are regressions (or if the licenses_check fails, then //engine/ci/licenses_golden/licenses_third_party must be updated to match the output of the failing test), then the user must fix these tests in their local checkout and push their changes again.

Codesign Engine Binaries

The user must validate post-submit CI builds for their merged engine PR have passed. A link to the web dashboard is available via conductor status. Once the post-submit CI builds have all passed, the user must codesign engine binaries for the merged engine commit.

Apply Framework Cherrypicks

The tool will attempt to auto-apply all framework cherrypicks. However, any cherrypicks that result in a merge conflict will be reverted and it is left to the user to manually cherry-pick them (with the command git cherry-pick $REVISION) and resolve the merge conflict in their checkout.

Publish Version

This step will add a version git tag to the final Framework commit and push it to the upstream repository. The presence of a tag affects what the flutter CLI tool reports the current version is.

Publish Channel

This step will push the Framework candidate branch to the upstream release branch (e.g. the stable branch). Once this push happens upstream, the release has officially been published, and the code will be available to existing Flutter users via flutter upgrade.

Verify Release

For the final step, the user must manually verify that packaging builds have finished successfully. The SDK compressed archives will not be available from the website until the packaging build has finished. The conductor will produce links to the dashboards for monitoring CI builds.
