Upgrade third_party/pyyaml to 03c67afd452cdff45b41bfe65e19a2fb5b80a0e8 (#54001) We were using a very old version of this library that broke with Python3.12. This updates to a Python 3.12 compatible SHA. The specific breakage at the former commit was that `collections.Hashable` was deprecated and moved to `collections.abc.Hashable` in Python 3.7. It was removed in Python 3.8. For anyone on newer versions of Python3, such as Python 3.9.6 which ships with macOS 15 Sequoia, this is broken. The error on versions of Python newer than 3.8 is: ``` ________ running 'python3 src/flutter/tools/pub_get_offline.py' in '/Users/chris/Developer/flutter/engine' Traceback (most recent call last): File "/Users/chris/Developer/flutter/engine/src/flutter/tools/pub_get_offline.py", line 167, in <module> sys.exit(main()) ^^^^^^ File "/Users/chris/Developer/flutter/engine/src/flutter/tools/pub_get_offline.py", line 157, in main if not package_uses_workspace_resolution(package): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/chris/Developer/flutter/engine/src/flutter/tools/pub_get_offline.py", line 76, in package_uses_workspace_resolution return yaml.safe_load(pubspec_file).get('resolution') == 'workspace' ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/chris/Developer/flutter/engine/src/flutter/tools/../third_party/pyyaml/lib3/yaml/__init__.py", line 75, in load return loader.get_single_data() ^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/chris/Developer/flutter/engine/src/flutter/tools/../third_party/pyyaml/lib3/yaml/constructor.py", line 37, in get_single_data return self.construct_document(node) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/chris/Developer/flutter/engine/src/flutter/tools/../third_party/pyyaml/lib3/yaml/constructor.py", line 46, in construct_document for dummy in generator: File "/Users/chris/Developer/flutter/engine/src/flutter/tools/../third_party/pyyaml/lib3/yaml/constructor.py", line 398, in construct_yaml_map value = self.construct_mapping(node) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/chris/Developer/flutter/engine/src/flutter/tools/../third_party/pyyaml/lib3/yaml/constructor.py", line 204, in construct_mapping return super().construct_mapping(node, deep=deep) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/chris/Developer/flutter/engine/src/flutter/tools/../third_party/pyyaml/lib3/yaml/constructor.py", line 126, in construct_mapping if not isinstance(key, collections.Hashable): ^^^^^^^^^^^^^^^^^^^^ AttributeError: module 'collections' has no attribute 'Hashable' Error: Command 'python3 src/flutter/tools/pub_get_offline.py' returned non-zero exit status 1 in /Users/chris/Developer/flutter/engine ``` ## Pre-launch Checklist - [X] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [X] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [X] I read and followed the [Flutter Style Guide] and the [C++, Objective-C, Java style guides]. - [ ] I listed at least one issue that this PR fixes in the description above. - [X] I added new tests to check the change I am making or feature I am adding, or the PR is [test-exempt].

Monorepo is:
With depot_tools installed and on your path, create a directory for your monorepo checkout and run these commands to create a gclient solution in that directory:
mkdir monorepo cd monorepo gclient config --unmanaged https://dart.googlesource.com/monorepo gclient sync -D
This gives you a checkout in the monorepo directory that contains:
monorepo/ DEPS - the DEPS used for this gclient checkout commits.json - the pinned commits for Dart, flutter/engine, and flutter/flutter tools/ - scripts used to create monorepo DEPS engine/src/ - the flutter/buildroot repo flutter/ - the flutter/engine repo out/ - the build directory, where Flutter engine builds are created third_party/ - Flutter dependencies checked out by DEPS dart/ - the Dart SDK checkout. third_party - Dart dependencies, also used by Flutter flutter/ - the flutter/flutter repo
Flutter's instructions for building the engine are at Compiling the engine
They can be followed closely, with a few changes:
goma_ctl ensure_start
is sufficient.Example build commands that work on linux:
MONOREPO_PATH=$PWD if [[ ! $PATH =~ (^|:)$MONOREPO_PATH/flutter/bin(:|$) ]]; then PATH=$MONOREPO_PATH/flutter/bin:$PATH fi export GOMA_DIR=$(dirname $(command -v gclient))/.cipd_bin goma_ctl ensure_start pushd engine/src flutter/tools/gn --goma --no-prebuilt-dart-sdk --unoptimized --full-dart-sdk autoninja -C out/host_debug_unopt popd
The Flutter commands used to build and run apps will use the locally built Flutter engine and Dart SDK, instead of the one downloaded by the Flutter tool, if the --local-engine
option is provided.
For example, to build and run the Flutter spinning square sample on the web platform,
MONOREPO_PATH=$PWD cd flutter/examples/layers flutter --local-engine=host_debug_unopt \ -d chrome run widgets/spinning_square.dart cd $MONOREPO_PATH
To build for desktop, specify the desktop platform device in flutter run
as -d macos
or -d linux
or -d windows
. You may also need to run the command
flutter create --platforms=windows,macos,linux
on existing apps, such as sample apps. New apps created with flutter create
already include these support files. Details of desktop support are at Desktop Support for Flutter
Tests in the Flutter source tree can be run with the flutter test
command, run in the directory of a package containing tests. For example:
MONOREPO_PATH=$PWD cd flutter/packages/flutter flutter test --local-engine=host_debug_unopt cd $MONOREPO_PATH
Please file an issue or email the dart-engprod team with any problems with or questions about using monorepo.
We will update this documentation to address them.
flutter
commands may download the engine and Dart SDK files for the configured channel, even though they will be using the local engine and its SDK.gclient sync
needs to be run in an administrator session, because some installed dependencies create symlinks.
