What's Changed

Detect ctags on more systems out of the box

• Homebrew's ctags (which is universal-ctags) now detected correctly on macOS — no manual CTAGS_COMMAND needed
• Three-tier detection: CTAGS_COMMAND env var → universal-ctags on PATH → ctags verified via --version
• Clear error when CTAGS_COMMAND is set but not found on PATH

Catch more file changes from editors like vim and emacs

• Atomic-write editors that write-to-tmp + rename now correctly trigger re-indexing, by tracking file inodes alongside mtime and size
• State hash bumped to v5 — caches from v0.3.0 are invalidated on first run

Faster and more robust git status parsing

• Added --no-ahead-behind to git status for faster execution
• Defensive handling for rename/copy entries in porcelain v2 output (not expected with --no-renames, but guards against edge cases)
• Fixed .gitignore-style exclude matching to use exact line comparison instead of substring (prevents false positives like .seek-cache-old matching .seek-cache)

Reduced memory usage for uncommitted file indexing

• Uncommitted files are now streamed through a bounded channel instead of buffered into a single unbounded slice, keeping at most 2×parallelism files in flight
• Non-regular files (FIFOs, sockets, devices) now skipped, preventing potential blocking reads
• Per-file reads use pre-sized buffer from Lstat instead of os.ReadFile, saving an extra Fstat syscall per file

Lock improvements

• Shared search lock is now non-blocking with poll timeout, preventing indefinite hangs if an indexer is stuck
• Added jitter to lock polling backoff to prevent thundering herd, and extracted a reusable pollLock helper

Bug fixes

• Zoekt builder Finish() is now always called even after Add errors, fixing a resource leak (ctags subprocess and open file handles)
• formatResults trailing newline removal uses single-byte check instead of strings.TrimRight, avoiding unintended stripping of content newlines

Internal

• fmt.Fprintf in repoStateFingerprint replaced with strings.Builder + strconv for fewer allocations
• strings.Builder.Grow() pre-allocates fingerprint buffer
• xxhash.WriteString replaces Write([]byte(...)) in computeStateHash, eliminating two allocations per hash
• Zoekt builder created lazily on first file, avoiding ctags process spawning when there are no dirty files
• Channel fully drained on error/panic paths to prevent goroutine leaks
• Lock logic consolidated from indexer.go into lock.go
