This is accomplished by a new directive in REPO.bazel, "ignore_directories()". It takes a single argument, a list of directories to ignore and it allows the same wildcards as glob(). This is done separately from .bazelignore to provide a migration path off of that weird single-purpose configuration file. Implementing this requires splitting RepoFileFunction into two: a part that parses the repository file and one that creates a PackageArgs instance. This was necessary to avoid a Skyframe dependency cycle: when a WORKSPACE file is present and it loads a .bzl file from a repository with a REPO.bazel file, the repo mapping for the main repository depends on the WORKSPACE file, which depends on the .bzl file, which depends on the IgnoredPackagePrefixesValue of its repository, which then depends on the repo mapping of the main repository and the one the .bzl file is in, which then depend on the WORKSPACE file. Fixes #7093. RELNOTES[NEW]: REPO.bazel now allows another directive, "ignore_directories()". It takes a list of directories to ignore just like .bazelignore does, but with glob semantics. Closes #24032. PiperOrigin-RevId: 693227896 Change-Id: Ia3e02a2bfe9caf999fc641f75261b528b19c1d03

Please take a look at the build failure (probably a missing dep in BUILD) |

Argh, sorry, PTAL. The cherrypick applied cleanly, I built |
