Repository navigation
feat(forge): P38 F2a repositories API, lifecycle, collaborators, branches - #301
Conversation
…servation, new_branch) and FINDINGS summary From the #297 follow-ups that belong before F2/F3: the row is the default-branch authority, admission reserves capacity before receive-pack and answers 507, contents writes with new_branch apply the policy to the target branch, and the FINDINGS summary line now says 24/24 and 2/24.
Public-only listings are empty 200s, listing counts are the visible count, rename is an explicit 422, interrupted creates are always rolled back, unknown directories move to orphans/ instead of being deleted, a data-dir lock and per-repo mutex serialize lifecycle operations, the runner always passes --git-dir, branch names are validated before git, the gate is restated to match how --pending works, and collaborator authority is decided.
…r and tail capture (wip)
… sort fidelity (wip)
Busy runner is 503 on every route, a git failure is an error and never an empty repo, reads take a shared per-repository lock so they cannot straddle a delete, the reconciler propagates database errors and keeps data in orphans/, a failed cleanup keeps its journal row, a relative data dir is made absolute, the layout is fsynced, PATCH default-branch is decided under the lock, search decodes q and its Link URLs repeat the query, collaborator and email input is validated, and the tests that would have passed on broken code are strengthened.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
One gone or damaged row fails the whole listing.
listed collects repo_json results with ? semantics. repo_json returns Err on the per-row liveness check and on per-row git failures. This causes two failures:
- Delete race: a repository can be deleted after
list_visiblereturns its row.with_readthen returnsOk(None), andrepo_jsonreturns 404.GET /repos/search,/user/reposand/orgs/{o}/reposthen answer 404 for the whole page. - Missing directory: the reconciler keeps a
liverow whose directory is missing (missing_dirs, Lines 507-513 inlifecycle.rs). For that row,gitread::is_emptyfails andgit_read_errseesstate == "live", so it answers 500. Every listing that includes the repository then returns 500 until an operator fixes it. Site admins see every repository, so their search breaks for as long as the directory is missing.
Skip rows that are no longer live. Also stop one damaged row from failing the page, for example by rendering empty: false or logging and skipping. Keep Busy as 503, because a_saturated_runner_answers_503_on_reads_and_writes_not_500 expects it.

Take the data-dir lock before migrations, one gone or damaged repository no longer fails a listing, a committed create or PATCH is reported from what it committed instead of a later git read, and only a unique violation means the name exists.

When a collaborator's access is revoked after list_visible selects the row but before listed calls resolve, the recheck returns None and this fallback still serializes the private repository with read permission. This makes /repos/search, /user/repos, and organization listings disclose the repository metadata after the caller no longer has access; treat None as a row to skip rather than as Perm::Read.

There was a problem hiding this comment.
When a live repository directory is missing or corrupt, show-ref exits with an operational error such as 128, but this condition maps every nonzero status to NoSuchBranch; consequently PATCH default_branch returns 422 and the identical check in delete_branch returns 404, hiding repository damage as bad user input. The official git show-ref --verify documentation specifies exit status 1 for no match, so other statuses should be propagated as Git failures.

When SC_FORGE_GIT is a relative path such as ./bin/git-wrapper—or Git is found through a relative PATH entry—find_git stores that relative path, but every spawn changes its working directory to the forge data directory. The executable is therefore looked up relative to the data directory rather than the directory from which sc-forge was launched, causing startup's version check to fail; canonicalize slash-containing configured and discovered paths before storing them.

This migration adds the repos and collaborators tables, but database_ready still probes only users, org_members, and tokens. If either new table is missing or unreadable while user_version remains 2, repository routes fail with 500 while both health endpoints continue returning 200, so deployment monitoring cannot detect that the newly added feature is unusable; extend the readiness table probe to cover the complete current schema.

For repositories whose description contains non-ASCII letters, a case-only variant of q does not match even though this filter is documented as case-insensitive. The query lowercases q with Rust's Unicode-aware conversion but applies SQLite's built-in lower() to the stored description; SQLite documents that this function only case-folds ASCII, so a description such as Éclair is omitted for q=éclair. Use a Unicode-aware collation/function or store a consistently normalized searchable value.
Useful? React with 👍 / 👎.
A row whose access vanished mid-listing is skipped, show-ref failures on a damaged repository are git failures not missing branches, the git path is always absolute, /healthz probes every table of the schema, and searches fold Unicode case in descriptions.

Summary
P38 slice F2a: the repository half of F2. The smart-HTTP transport, hooks, ref policy, admission control and threat-model pass #1 are F2b (split agreed; plan reviewed first:
docs/superpowers/plans/2026-10-23-p38-f2a-repos-api.md).Decisions worth a look (spec: "F2a decisions (as built)"):

X, D, K and M stay out until their routes exist (they make ordinary recorded calls to unbuilt routes, which--pendingcannot hide).cargo test -p scl-forge: 65 unit (every row of the crash-recovery table, runner process-group kill, env scrub, access matrix) + 33 + 17 e2e + 3 route-table; clippy-D warningsclean (local 1.99; CI pins 1.96).null(git reads a vanishedrefs/headsas no refs). Fixed with the shared per-repo lock; the test now asserts every 200 equals the pre-delete list, over three consecutive runs.--data-dir, layout fsync, cleanup journal, PATCH race), plus the rest.Merge Danger
