Overview

Package digest computes git-blob hashes for indexed files. It reads HEAD-tree and staging-index blob SHAs via go-git (no shelling out) and falls back to hashing working-tree bytes for dirty or untracked files.

Types

type Source 

type Source struct {
	TreeBlobs  map[string]plumbing.Hash
	IndexBlobs map[string]plumbing.Hash
}

Source caches blob hashes for paths that go-git already knows about (tracked-and-clean files), avoiding rehashes during sync.

func Load 

func Load(ctx context.Context, root string) (*Source, error)

Load opens the git repository rooted at root and prefetches blob hashes for the HEAD tree and the staging index. A non-git directory returns an empty Source (every file falls through to working-tree hashing).

func (*Source) For 

func (s *Source) For(path string, body []byte) plumbing.Hash

For returns the git-blob hash to record for path. It prefers the staged blob (covers "staged but committed body is different"), then the HEAD tree, and finally hashes the working-tree body in-process. body is only read when the cache misses, so callers can pass nil for clean files.

func (*Source) Tracked 

func (s *Source) Tracked(path string) bool

Tracked reports whether path is present in either the HEAD tree or the staging index. Useful when sync needs to decide whether to trust the cached hash without re-reading the file body.
