Explanation

Fixes #5312

This updates the TODO open check script to be locally runnable rather than requiring the developer to manually download the list of issues from GitHub to analyze. This simplifies things and allows the script to be easily run within the static_checks.sh script. This is being done via interacting directly with GitHub using its RESTful API (see https://docs.github.com/en/rest/issues/issues?apiVersion=2022-11-28#list-repository-issues) in conjunction with the user's local auth token used to set up their gh tool (which needs to be set up, hence the changes to the wiki documentation and clear error messages from the new GitHubClient utility).

To further simplify things, a regenerate mode was added to regenerate the TODO exemptions textproto file (which is helpful for #4929 hence why this comes before that PR).

The new command syntax to perform the TODO check is:

bazel run //scripts:todo_open_check -- <path_to_dir_root> <path_to_proto_binary> [regenerate]

With a specific example to just perform the check:

bazel run //scripts:todo_open_check -- $(pwd) scripts/assets/todo_open_exemptions.pb

And an example to also perform regeneration:

bazel run //scripts:todo_open_check -- $(pwd) scripts/assets/todo_open_exemptions.pb regenerate

Some other things specifically to note:

  • TODO exemptions needed to be updated in this PR due to TODO utility & test changes. The new file was created using the new regenerate functionality.
  • The TODO check has been added to the end of static_checks.sh.
  • The GitHub CI workflow was updated to use the new script syntax appropriately.
  • This is the first time scripts have been updated to integrate with Retrofit, and this setup is going to be reused in the future for other services.
  • The data model for issues has been updated to better represent the remote data structure.
  • Moshi is being used along with Retrofit for an easier interaction with GitHub as a remote endpoint. All of this has been wrapped in a new GitHubClient.
  • GitHubClient is designed to download all issues regardless of length (whereas before the manual download step was limited to the first 2000 issues of the repository) using pagination.
  • New tests were added to verify the regenerate flow (and properly set up the mock OkHttp server since the script now relies on an HTTP endpoint to download the GitHub issues itself).
  • GitHubIssue is exempted from tests since it's just a basic data structure, so there's no specific logic to test.
  • GitHubService is exempted from tests since it's a template to generate code via Retrofit's annotation processor, so there's no specific logic to test.
  • All scripts proto libraries were updated to use normal Java (rather than Java lite) generation to provide text format support.
  • The file paths included in TodoOpenCheck's output has been simplified to be relative to the repository root rather than using absolute paths (for parity with many other app scripts).
  • Since GitHubClient's tests required interacting with gh, a new FakeCommandExecutor was added (along with its own tests) to provide support for orchestrating local utilities. This may be useful in other tests in the future, though some of those script tests intentionally integrate with environment commands like git and bazel.

For UI-specific PRs only

This is an infrastructure-only PR.

These issues were found after I started using a new development
environment.
ProfileAndDeviceIdFragmentTest had been updated to use a newer fragment
initialization pattern, but that's no longer needed and seems to be
causing what appears to be timing discrepancies between local dev and
CI.
The issue ultimately arose from test parameters being initialized after
they're needed in the launched UI. This type of change was tried earlier
in the branch, but reverted since it didn't seem necessary. It is,
however, necessary when there are environment differences (e.g. local
vs. CI) or when running certain tests individually.

Due to the difficulty in finding this issue, ActivityScenarioRule has
been added as a prohibited pattern in the static regex checks (along
with ActivityTestRule since that's deprecated and discouraged, anyway).
The test was suffering from some proto encoding inconsistencies that
seem to occur between some development machines vs. on CI. The fix
improves the test's robustness by extracting the raw encoded string,
verifying that the other outputs in the intent message correctly
correspond to that string, and that the string (as a parsed proto)
contains the correct values. As a result, the test no longer depends on
a hardcoded encoding value to be present for verification. This does
result in a bit more logic than is generally good to have in a test (and
it lengthened the test code quite a bit), but it seems necessary in this
particular case.
This does a bunch of other small things, too, but the main difference
here is introducing support for interacting with GitHub via its REST API
rather than requiring the user to use the 'gh' tool locally (though the
gh CLI tool is still needed for maintaining authentication access).
Tests still need to be added, and some cleanup is needed once the
branch's base is adjusted.
This is a script-specific dispatcher which will allow for better
asynchronous support in upcoming PRs (especially for command execution).
This change serves to prepare for those changes.
The main change here is ensuring that Bazel 4.0.0 is used & bzlmod
disabled in newer versions of Bazel when running operations in a test
Bazel environment.

This commit also introduces some more timing tweaks on CommandExecutor
for some tests, though these only affect very specific tests (as many
script tests directly call a script's main() function and thus don't
overwrite its executor behavior).

This commit attempted to introduce "--batch" mode to runs, but the
isolation didn't actually seem to improve stability and, instead,
substantially slowed down some of the tests.

Plus, actually makes use of the new script background dispatcher in
CommandExecutorImpl to make the new wiring make more sense (though its
real utility will come in a follow-up PR).
This makes the TODO open check script runnable using the script
background dispatcher, and fixes some tests so that they pass now.

More documentation and testing work is still needed to finalize this PR.

This was done by removing the //testing dependency and, instead, having
instrumentation targets depend on the direct module within //testing
that they need to build. This module & its corresponding implementation
binding (and tests) needed to be moved out of //testing and into their
own /firebase package.

…port (#5313)

## Explanation
Fixes part of #5312
Fixes part of #59

This PR helps prepare for changes coming in #5315 and #4929 (the latter
of which is the start of the main upcoming Bazel migration PR chain) by
introducing one main scripts-based change:
``ScriptBackgroundCoroutineDispatcher``: a Kotlin coroutine dispatcher
for executing asynchronous tasks in scripts that also supports proper
Java executor service shutdown (so that scripts don't hang). This
dispatcher is multi-threaded to help simplify executing large numbers of
parallel background tasks.

All scripts have been migrated over to running their primary operations
within the context of this new dispatcher. Relevant script utilities
have been updated to use it, including ``CommandExecutor`` (though this
is mainly a placeholder change for the main executor changes which are
coming in #4929).

Miscellaneous details to note:
1. A bunch of 'e.g.' typos were fixed in
``GenerateMavenDependenciesList.kt`` and
``wiki/Updating-Maven-Dependencies.md``. These aren't functionally
needed, they were just something I noticed while developing.
2. ``kotlinx-coroutines-core`` was updated from 1.4.1 to 1.4.3 in order
to work around Kotlin/kotlinx.coroutines#2371
which was causing flakiness in one of the new dispatcher tests.
3. ``testClose_pendingTaskLongerThanCloseTimeout_taskIsNotRun``
intentionally takes ~2 seconds to run in order to provide some assurance
that, without cancellation, the task _would_ run and the test _would_
fail (this has been manually verified in a few different situations of
the dispatcher and/or test changing; some changes won't result in a
failure due to how cancellation works internally for executor service &
the converted coroutine dispatcher).

Note that historically these changes were originally part of #4929, but
they were split out so that they could be used by #5315 (which ended up
being convenient to include prior to #4929).
