feat: phase 1 — repository discovery and status scanning
Implement the core data layer that everything else builds on: walking a parent directory for Git repositories and snapshotting each repository's state via porcelain commands. Domain model (pkg/status): - RepoStatus enum with zero value = StatusUnknown (invalid/unset), covering clean / modified / ahead / behind / diverged / detached / bare / error - RepoInfo snapshot: path, name, remote URL, branch, detached flag, staged / modified / untracked file lists, ahead/behind counts, stash count, error - ScanResult with computed Summary counters and NeedsAttention filter Git wrapper (internal/git): - Executor built with functional options (binary, timeout, env), defaults to "git" with a 10s per-command timeout so a hung repository can never stall a scan; context cancellation honoured via exec.CommandContext - Status() validates with rev-parse --is-bare-repository (bare repos are reported as StatusBare and skipped), then parses `git status --porcelain=v2 --branch -z` - Parsing uses the NUL-separated v2 format so paths with spaces, quotes, and tabs survive verbatim (no C-quoting to decode); rename records (type 2) and ahead/behind lines (# branch.ab) are handled, unknown tokens are ignored for forward compatibility - Best-effort remote URL (git config --get-regexp) and stash count Discovery (internal/scanner/discover.go): - WalkDir-based traversal that never descends into .git internals - Detects working trees via .git directory or .git pointer file (linked worktrees, submodule checkouts) and bare repos via a *.git directory carrying its own HEAD/objects/refs - WithExclude glob patterns (matched against full path and base name) and WithMaxDepth depth limiting as functional options - Walk errors (e.g. permission denied) are aggregated and returned alongside partial results via errors.Join; cancellation is propagated Scanner (internal/scanner/scanner.go): - Concurrent status scanning with a bounded worker pool (errgroup + SetLimit, default 8 workers) - Per-repo failures become StatusError entries instead of aborting the pass; a cancelled context aborts the whole scan Testing: - Table-driven parser tests with canned NUL-separated porcelain output - Integration tests against a real git binary (clean / modified / staged / stashed / detached / bare / non-repo) - Discovery tests over a fixture tree with nested repos, a bare repo, a linked worktree, and an exclusion target - Scanner tests for mixed success/failure, bounded concurrency, and cancellation; everything runs under -race Note: LastFetch from the original plan was dropped — the only reliable source is a reflog of the remote-tracking ref, which does not exist on fresh clones, so it would always be misleading. The model remains extensible if a fetch-history feature is wanted later. |
