Consolidates the code to find all changed file paths into the `PackageLoopingCommand` class that is the base of almost all of the repo tooling commands. This in a preparatory PR for a future change to allow each command to define a list of files or file patterns that definitively *don't* affect that test, so that CI can be smarter about what tests to run (e.g., not running expensive integration tests for README changes).
A side effect of this change is that tests of almost all commands now need a mock `GitDir` instance. This would add a lot of copy/pasted boilerplate to the test setup, and there is already too much of that, so instead this refactors common test setup:
- Creating a memory file system
- Populating it with a packages directory
- Creating a RecordingProcessRunner to mock out process calls
- Creating a mock GitDir that forwards to a RecordingProcessRunner
into a helper method (using records and destructuring to easily return multiple values). While some tests don't need all of these steps, those that don't can easily ignore parts of it, and it will make it much easier to update tests in the future if they need them, and it makes the setup much more consistent which makes it easier to reason about test setup in general.
Prep for https://github.com/flutter/flutter/issues/136394
A non-Flutter package can have Flutter-based tests (e.g., cupertino_icons), in which case we need to use `flutter test` rather than `dart test` just like we would for a package with a non-dev Flutter dependency. This updates the `requiresFlutter` check to include dev dependencies as well as normal dependencies.
Adds a new command that adds `dependency_overrides` to any packages in the repository that depend on a list of target packages, including an option to target packages that will publish a non-breaking change in a given diff.
Adds a new CI step that uses the above in conjunction with a new `--run-on-dirty-packages` to adjust the dependencies of anything in the repository that uses a to-be-published package and then re-run analysis on just those packages. This will allow us to catch in presubmit any changes that are not breaking from a semver standpoint, but will break us due to our strict analysis in CI.
Fixes https://github.com/flutter/flutter/issues/89862
pub.dev deducts points for having a pubspec.yaml `description` that is too short or too long; several of our plugins are losing points on this. To ensure that we are following—and modeling—best practices, this adds a check that our `description` fields meet pub.dev expectations.
Fixes our existing violations. Two are not published even though this only takes effect once published:
- camera: We change this plugin pretty frequently, so this should go out soon without adding a release just for this trivial issue.
- wifi_info_flutter: This is deprecated, so we don't plan to release it. It has to be fixed to allow the tool change to land though.
Packages are the primary conceptual object in the tool, but currently they are represented simply as Directory (or occasionally a path string). This introduces an object for packages and:
- moves a number of existing utility methods into it
- sweeps the code for the obvious cases of using `Directory` to represent a package, especially in method signatures and migrates them
- notes a few places where we should migrate later, to avoid ballooning the size of the PR
There are no doubt other cases not caught in the sweep, but this gives us a foundation both for new code, and to migrate incrementally toward as we find existing code that was missed.
