v1.0.0

1.0.0 (2026-06-27)

• feat(db)!: adopt kysely, kanel codegen, and kysely-owned migrations (3f6878a)
• feat(protocol)!: serve full git clone over smart-HTTP v2 (9dd0aea)
• feat(storage)!: stream ingest through binary COPY and lift the push-size ceilings (259c210)
• refactor(storage)!: collapse the repo_view projection onto git_object (77aa854)

Bug Fixes

• gc: stamp last_pushed_at after the ingest commits, not inside the txn (b83a768)
• http: decode gzip-compressed request bodies (406e304)
• http: return git smart-HTTP responses as arraybuffer bodies (d08aae5)
• object: fail loud on malformed or truncated git trees (35b5ec7)
• pack: resolve delta bases by fixpoint to handle chained ref-deltas (df939a4)
• protocol: serve empty pack for zero-want fetch to match git's oracle (11961e4)
• protocol: surface wire-fault and missing-want conditions as clean client errors, not 500 (5e3c7e7)
• release: drop npm provenance so scoped token publish works (49b80a8), closes npm/cli#8976
• testing: apply migrations directly to isolated schemas to avoid drop races (3701286)
• testing: handle benign git stdin EPIPE so the worker no longer crashes (8f40902)

• push: apply ref updates atomically for --atomic pushes (48f7eae)
• push: delete refs via delete-only pushes (3829d39)
• push: ingest thin packs and update refs via compare-and-swap (6022e27)
• push: reject pushes whose pack omits reachable objects (6cd57bf)
• repo-view: project pushed working trees into queryable Postgres rows (35c31ae)
• scaffold pggit git-remote-over-postgres server (f1e5903)
• storage: derive and store the commit/tree/tag DAG as queryable edges (fb33d41)
• store: add postgres-backed git object store (1a560f6)
• store: add postgres-backed git refs store (6df21c0)

Performance Improvements

• harness: add diagnostic clone-performance harness (dbc180f)
• storage: replace the O(N) connectivity walk with bounded SQL queries (25c7a1f)

BREAKING CHANGES

• the store factories createObjectStore, createRefStore, and createSnapshotStore now accept a porsager Sql client instead of a Kysely<Database>.
• the queryable file view moves from repo_view_files/repo_view_blobs to repo_file joined to git_object, and RepoBackend drops getObject and gains an includeTag argument on buildPack.
• migration 0001_init is rewritten to the postgres-native schema (repos/git_object/git_ref) and drops the pack-blob model (packs/objects/refs, the dead_at soft-delete reaper, the offline repack worker); existing databases must be recreated.
• createObjectStore and createRefStore now require a Kysely rather than a postgres Sql and no longer provide migrate(); apply schema via db.manage or migrateToLatest.
• createGitApp now requires injected object/ref stores (GitAppDeps) and no longer accepts CreateGitAppOptions/databaseUrl; the removed AppEnv type and the old startServer-builds-app behavior are replaced by serveOnPort.
