Mike Kruskal	9ced4cb365	Implement a workaround for macOS/Bazel flakes. Bazel has a 2 minute timeout for their internal `xcrun` call, which can be exceeded on our github runners about 5% of the time. This leads to flakes and opaque errors, but is a one-time cost. Subsequent xcruns finish in seconds, so we can just do an initial call w/o a timeout before running Bazel. With this change our total flake rate drops from ~30% to nearly 0% for our full suite of tests See https://github.com/bazelbuild/bazel/issues/17437 for background.

Mike Kruskal	0ed65fd08f	Enable github caching of Bazel's repository cache. This should substantially reduce network flakes, since most builds will no longer need to download external dependencies. Because these caches actually get pretty expensive (~300 MB just from 1 openjdk dependency), we've taken some precautions: 1) The caches only get updated on push events (i.e. post-submit jobs) 2) Only a single job will push a new cache for any os/branch/commit combination. This will be whichever job finishes its bazel run first, and also has updates for the cache. Over time, the cache should expand to the full set of transitive dependencies as the quicker jobs stop pushing updates. 3) A clear_caches workflow has been introduced to reset the caches in case they grow too large. This will run monthly for now, but can also be run manually. PiperOrigin-RevId: 508133044	2 years ago
