Problem

With origin as a fork and another remote as the GitHub base, T3 sends a bare head branch and fork-to-upstream PR creation fails. See #7382.

Change

Use the provider-resolved target remote when deciding whether the head is cross-repository, so fork PRs use owner:branch. Add focused lookup and creation regression tests.

Scope and approval

Focused fix for the existing PR creation/lookup behavior; no UI, API, or settings changes.

Verification

Regression tests cover fork target selection, provider-selected targets, and local branch aliases.

🟡 Medium git/GitManager.ts:1840

A fork PR is reported as missing when its local branch uses an ordinary alias, such as review-main tracking contributor/main: this condition skips the cross-repository lookup, and the missing review-main remote ref makes resolveLookupHeadContext return lookup: false without querying the provider. Preserve the cross-repository exemption alongside the synthetic worktree-name check.

Fixed in 509c4c0c. The lookup guard now preserves both conditions: cross-repository heads and synthetic t3code/pr-/... worktree branches. I also added a regression test for an ordinary local alias (review-main tracking the forks main) and updated the existing git-command expectation for the new gh-resolved base-remote read.

Walkthrough

GitManager now resolves the pull-request target remote using provider information or GitHub’s configured base remote. It uses that target in branch and repository identity checks, validates cached pull requests against target identity, and recognizes pull-request worktree branches during lookup.

Changes: Pull-Request Target and Lookup

Layer / File(s)Summary
Select target remote and resolve PR context
apps/server/src/git/GitManager.ts, apps/server/src/git/GitManager.test.ts		GitManager identifies a target remote from provider capability or GitHub’s gh-resolved base setting, with origin as a fallback. Branch context and repository identity checks use that target. Tests cover fork PR lookup and creation when the base differs from origin, including a provider-selected target despite a stale base mark.
Validate remembered PR identity
apps/server/src/git/GitManager.ts		Remembered PR data includes the target remote URL key. Cached results are rejected when both stored and current target keys exist and differ.
Recognize PR worktree branches
apps/server/src/git/GitManager.ts		A shared t3code/pr- prefix and matching predicate identify pull-request worktree branches. Lookup considers matching branches eligible.

This change makes fork pull-request creation use the correct base remote. The only remaining concern is a small, unmeasured extra cost from rescanning remotes during lookup. It is safe to merge, with that follow-up noted.

Full details: Title check

Explanation

The title "fix(git): create pull requests from fork heads" follows the conventional commit format and matches the main change. The PR makes GitManager resolve the change-request target remote from the GitHub-resolved base remote, so a fork-tracking branch sends an owner-qualified head (fork-owner:feature) instead of an unqualified one. The title names the fork-head case, which is the core of the fix. It does not cover the cache and worktree-lookup changes, which is expected for a title.

Full details: Linked Issues check

Explanation

[#7382] The objective is to compare the head remote with the provider's resolved base repository, not with the remote named origin, so that a fork-only branch sends an owner-qualified head.

Implementation at head 25de303 (whole-PR diff against merge base b90e554):

  • resolveChangeRequestTargetRemoteName (GitManager.ts) selects the base remote. It first uses a unique remote whose URL the provider's createsChangeRequestsIn accepts. Otherwise it uses the unique remote.<name>.gh-resolved base entry, and otherwise origin.
  • resolveBranchHeadContext now compares remoteRepository with baseRepository, which is the resolved target. isCrossRepository, isForeignRemote, and isOnlyRemote use the same target. For the issue case (origin = fork, upstream = base, remote.upstream.gh-resolved=base), the fork branch becomes cross-repository. ownerHeadSelector (contributor:feature/fork-pr) is then sent instead of the bare headBranch.
  • The added test creates a fork PR when GitHub resolves a separate base remote covers this case. It asserts baseRefName === "main" and headSelector === "contributor:feature/fork-pr".
  • The added test uses the Provider-selected target remote over a stale GitHub mark covers the provider-selected target path.

The acceptance criterion (cross-repository PR from <you>:<branch> into the base repository) is supported by this code path. Reviewer evidence is code reading only. The reviewer did not execute the tests. The PR description's Changes bullet describes only the gh-resolved selection. The code also applies the provider capability check first. This is description drift, not a missing requirement.

Full details: Out of Scope Changes check

Explanation

[#7382] All changed hunks relate to target-remote identity or its tests:

  • Target identity: resolveChangeRequestTargetRemoteName, resolveGhBaseRemoteName, the fallback parameter of targetsOnlyRemote, and the baseRemoteName replacement of literal origin in resolveBranchHeadContext and the remote URL key read. These implement the issue's proposed fix.
  • Cache validation: targetRemoteUrlKey in LastKnownPr and resolveLastKnownPr. Cached PR state is invalidated when the target changes. This follows from the target change. The issue does not request read-path changes. The shared resolveBranchHeadContext feeds both lookup and creation, so the lookup adjustments are consequences of the same target identity, not a separate read-path fix.
  • Worktree lookup: PULL_REQUEST_WORKTREE_BRANCH_PREFIX and isPullRequestWorktreeLocalBranchName, which keep synthetic t3code/pr-<number>/... branches eligible for lookup. The author lists this in the PR description. The prefix constant leaves the generated branch name unchanged.
  • Tests: the lookup test for a default-branch alias, the config command count update, and the two creation tests. These support the changed behavior.

No unrelated provider API, UI, Windows, or single-repository behavior change is evident in the diff.

Full details: Description check

Explanation

The description is mostly complete. It has Problem, Change, Scope and approval, and Verification sections, and it links issue #7382. It states the root cause and the fix clearly. Gaps remain. The Scope and approval section does not link a triaged bug issue with maintainer approval, and it does not explain why the fix qualifies without one. The Verification section names the regression tests but does not report observed results. It also says local test execution was skipped, and it does not list the reported validation commands or state that they were not run. The template also asks for the model and harness if an agent did the work, and the description does not say whether one did. The Problem section gives reproduction context only loosely. The author should add these items. The description is still mostly complete, so the check passes with notes.

Classify the head against the selected provider’s target.

If GH_REPO targets upstream while gh-resolved marks the fork, GitManager sends a bare head and creation can fail. The same mismatch affects Forgejo when origin is the target. A URL-less marked remote can also cause GitManager to reject an existing same-repository GitHub PR.

Use the selected provider’s target resolution for head classification. Add regression tests for these configurations.

Fixed in 25de3030. GitManager now uses the selected provider’s createsChangeRequestsIn hook to identify the target remote when available, so provider-resolved targets take precedence over a stale gh-resolved mark. GitHub falls back to the unique gh-resolved base remote; providers without target resolution retain the origin fallback. Added a regression test where the provider-selected upstream target overrides an origin base mark.

@exherb Thanks. The new test covers the stale-mark case with a fake provider hook.

One case from the finding remains. With origin and upstream configured, no GH_REPO, and a URL-less remote.ghost.gh-resolved=base, the GitHub hook can match both real remotes. GitManager then falls back to ghost, while the GitHub provider resolves upstream. An upstream branch can be classified as cross-repository, causing an existing same-repository PR to be rejected.

Please check that case against the provider’s resolved target and add a regression test. This assessment is based on code inspection; I did not run tests.

5Learning: In this repository, GitHub PR target resolution uses parseGitHubRepositorySelector for GH_REPO. An unparseable GH_REPO falls through to resolveGitHubRepository, which considers remotes and gh-resolved with the provider's host context. GitManager head classification must follow these provider semantics; a sole remote does not by itself establish a same-repository head.

Fixed in 25de3030. The cached-lookup assertion now includes four config reads: two base-remote lookups and two settled-fingerprint reads, followed by the two for-each-ref calls.

@exherb Thanks for the fix. In 25de3030, the assertion at Line 1122 now expects four config commands and two for-each-ref commands. The assertion sorts the commands before comparing them.

I did not run the test.

Add the missing config entry.

Each cached lookup runs one config command for the base remote and one for the settled fingerprint. The assertion expects only three across both lookups, so the test fails.

Restore the headContext.isCrossRepository reference.

The bare identifier is out of scope and fails typechecking. When the preceding conditions are false, lookup can also fail with a ReferenceError.

apps/server/src/git/GitManager.ts: 1

1616-1622: External image Trivial · Performance & Scalability · Poor tradeoff

Cache the target-remote scan on the PR lookup identity path.

resolveChangeRequestTargetRemoteName runs git remote, then reads each remote URL and calls the provider hook for each remote. It uses concurrency: "unbounded". Each call to resolveBranchHeadContext repeats this work.

On a cached PR lookup, resolvePrLookupRepositoryIdentity calls this function directly at line 2582. That call is outside rememberPrLookupGitState, so PR_LOOKUP_GIT_STATE_TTL and the fresh flag do not apply to the remote scan. Only the identity function's own branch.<name>.remote and remote-URL reads use that cache.

The cost grows with the number of remotes and with the cost of createsChangeRequestsIn. The impact is not measured. Measure the cost on a repository with several remotes. If it is significant, cache the target remote name with the same TTL and fresh semantics as the other remembered git state.
