[9.1.1] downloader: fix opaque file URI names (https://github.com/bazelbuild/bazel/pull/29549) - #29658
Merged
Conversation
Fix a Bazel 9.1.0 regression where repository_ctx.download could crash on opaque file URIs such as file:../archive.tgz. The URL-to-URI migration changed basename extraction because URI.getPath() returns null for these inputs, unlike URL#getPath(). DownloadManager then passed null to PathFragment.create while building distdir candidate names. Reuse one basename helper for download destinations and distdir lookups, falling back to the scheme-specific part for opaque URIs. Add regression coverage for the explicit-output and typed-download paths. Fixes bazelbuild#29393. Closes bazelbuild#29549.
