Public API additions (src/tree):
- src/tree/types.rs: new TreeEntryWithLatest { entry, latest } pair
(entry: TreeEntry, latest: CommitInfo) with Serialize/Deserialize
derives so it can flow through the cache payload path.
- src/tree/helper.rs: parse_ls_tree_entries — NUL/newline-delimited
ls-tree stdout -> Vec<TreeEntry>. Mirrors the git ls-tree -r -t
layout (mode SP type SP oid TAB name). Errors are reported with the
1-based line index via BabyError::CommitParse for parity with
parse_commit_output.
- src/tree/usecase.rs: GitBaby::tree_entries_with_latest(revision, path)
-> Vec<TreeEntryWithLatest>. Implementation:
1) spawn a single `git ls-tree -r -t <rev> -- <path>` to enumerate
blobs/trees,
2) parse with parse_ls_tree_entries,
3) fan out N parallel `tree_latest_commit(rev, path)` lookups via
tokio::task::JoinSet,
4) reassemble preserving the ls-tree order.
Subtree paths are normalized: tree entries get a trailing `/` for
the lookup so callers don't have to know whether a name is a tree.
Path safety reuses share::validate_local_no_escape, and revision
reuses share::validate_revision_non_empty.
- src/tree/mod.rs: re-export TreeEntryWithLatest alongside the
existing tree public surface.
Trait bound change (src/repo.rs):
- RepositoryFacade now requires Send + Sync in addition to 'static.
This is needed so the JoinSet-driven fan-out above can share the
Arc<dyn RepositoryFacade> across spawned tasks. Existing single-task
implementations are unaffected; the only callers that needed to
add Sync explicitly are those keeping non-Sync state inside their
facade (none in-tree).
Tests (tests/tree.rs, new):
- tree_entries_with_latest_whole_tree: enumerate a flat repo and
verify every (path, latest_commit_id) pair round-trips against the
revwalk.
- tree_entries_with_latest_subtree: scope to a sub-path and check
only entries under it are returned, in ls-tree order.
- tree_entries_with_latest_rejects_bad_input: empty revision and
path-traversal attempts both surface BabyError without spawning a
child process.
- Uses the existing TestFacade skeleton, temp_repo helper, and
git_commit / index_commit / write_file fixtures. Counter uses
AtomicU32 + COUNTER.fetch_add for unique temp dirs across tests,
matching the pattern from other integration tests.
CI: cargo build + cargo test (64 passed, +3 new) green.
Notes:
- TreeEntryWithLatest has #[serde(default)] on no fields today, but
it follows the additive-only convention documented in AGENTS.md
(cached serde payloads only ever add new fields).
- BREAKING for RepositoryFacade implementors that are not Sync.
None ship in-tree; downstream consumers must add Sync if they hold
non-Sync interior state.
Introduce src/server/ as a streaming-first git/lfs server surface. All
request and response bodies cross the API as
Box<dyn AsyncRead + Unpin + Send + Sync> (alias BoxedAsyncRead) — no
Vec<u8> bodies, no read_to_end convenience, no http crate.
What's in the box:
- src/server/mod.rs: re-exports + pipe re-export of
command::cmd::DEFAULT_OUTPUT_CAP_BYTES as server::DEFAULT_OUTPUT_CAP_BYTES
- src/server/backend.rs: ServerBackend async-trait (authorize,
list_refs_stream, produce_pack_stream, ingest_pack_stream,
lfs_get_stream, lfs_put_stream). Every method currently returns
ServerError::Unimplemented("...") placeholders — the wiring is
real, the bodies are intentionally empty.
- src/server/request.rs: ServerRequest (not Clone, body is a boxed
reader), HeaderMap = HashMap<String, String>, RefUpdateBatch
(oid strings, no gix::ObjectId), BoxedAsyncRead alias
- src/server/stream.rs: StreamGuard (Clone + Send + Sync) carrying
cancel() / handle() so spawned workers can race the request
- src/server/endpoint.rs, error.rs, limits.rs: EndpointKind enum,
ServerError, DEFAULT_LFS_OBJECT_CAP_BYTES (5 GiB cap, separate from
the 64 MiB output cap)
- tests/server.rs: PlaceholderBackend skeleton + ENV_LOCK +
200 ms cancel convention reused from tests/env.rs and tests/pipe.rs
Public API impact on GitBaby:
- Drop pipe from GitBaby::new — the server owns its own stream
lifecycle, so the Pipe parameter is no longer required at
construction time. Existing callers must be updated:
- before: GitBaby::new(facade, pipe)
- after: GitBaby::new(facade)
Documentation:
- AGENTS.md gains a "Planned but unimplemented (streaming-first
server)" section documenting the deliberately-empty contracts so
future contributors don't "fill them in" without a concrete
git/lfs protocol task.
CI: cargo build + cargo test (61 total, 23 new from server suite)
green.
