project: reuse loaded refs when resolving HEAD

2026-08-31T19:33:39+00:00

When the regular checkout has already loaded GitRefs, derive its current branch and HEAD object from that snapshot instead of spawning symbolic-ref or rev-parse again. Keep linked Git worktrees on their worktree-specific HEAD path because the shared repository HEAD is not authoritative for them.

git_refs: load HEAD with the ref snapshot on Git 2.45

2026-08-31T18:57:39+00:00

Use for-each-ref --include-root-refs to resolve attached and detached HEAD in the same process as refs/* on Git 2.45 and newer. Limit the patterns to HEAD and refs so volatile pseudo-refs do not enter the cache, and retain the existing fallback for older Git and unborn HEADs.

git_refs: read refs via git plumbing for files/reftable

2026-03-17T21:28:39+00:00

Replace direct `packed-refs` file parsing with `git for-each-ref` plumbing to support both `files` and `reftable` backends.

git_refs: fix crash with binary . files in .git/refs/

2021-02-28T16:07:24+00:00

On macOS, the Finder app likes to poop .DS_Store files in every path that the user browses. If the user pokes around the .git/ tree, it could generate a .DS_Store file in there too. When repo goes to read all the local refs, it tries to decode this binary file as UTF-8 and subsequently crashes. Since paths that begin with . are not valid refs, ignore them like we already do with paths that end in .lock. Also bump the check up to ignore dirs that match since that follows the git rules: they apply to any component in its path, not just the final path (name). We don't implement the full valid ref algorithm that git employs as it's a bit complicated, and we only really need to focus on what will practically show up locally.
