fix(forgejo): prefer the deepest-mounted login when a root login also matches #35916

Openjuliusmarmingewants to merge 2 commits intomain fromrefs/pull/35916/headopened View on GitHub

juliusmarmingecommented

matchForgejoLogin accepted a root (empty-path) login for every HTTP(S) remote on its host, alongside a more specific mounted-instance login such as https://host/gitea. Because the two matched URLs differ, it returned undefined (the default-login tie-break only runs when all matching URLs are equal), and resolveRepository reported 'No matching Forgejo login'. For HTTP(S) remotes with a path, the matches are now narrowed to the logins with the longest login URL path before the existing single-match and same-URL-default rules run. The deepest mount is the one whose base path is a prefix of the remote, so a root login no longer hides a mounted instance's login. SSH matching and host-only lookups (empty remote path) are unchanged. No new regex or parser: it reuses parseForgejoRemote, which is linear.

Fixes pingdotgg/t3code#35904

Reproduction on main

On origin/main 025942d76a (Node v26.12.1), ran the reporter's repro-mount.sh unchanged against a fresh worktree. It imports the production ForgejoCli.resolveRepository with an injected process runner that returns synthetic tea login list --output json output. Output: 'Control: mounted-instance resolves owner/repo', then with logins https://forge.example and https://forge.example/gitea: 'authentication; No matching Forgejo login...' and 'RESULT: defect reproduced'. Also added an assertion to the existing test 'does not choose a default Forgejo login across ambiguous SSH server ports' in packages/source-control-forgejo/src/server/ForgejoSourceControlProvider.test.ts. It gives logins http://forgejo.local:4000 and http://forgejo.local:4000/gitea and resolves remote http://forgejo.local:4000/gitea/maria/project.git. It fails on main: expected 'one', received undefined.

Evidence

Run the real T3 server with fresh state on each commit. Add a project whose remote is https://forge.example/gitea/owner/repo.git. Confirm a summary request succeeds with the mounted login alone; add the root login (marked default), then request an uncached summary for the same repository.

Environment on both sides: Linux x86_64, Node v26.12.1, loopback HTTP/WebSocket, synthetic tea subprocess responses. Images are rendered excerpts of captured server responses, not web-client screenshots.

Reproduction driver and seed fixture.

Not shown:

  • Released tea and live Gitea authentication/network behavior were not exercised; the reproduction used synthetic tea login and API subprocess responses.
  • Web, desktop and mobile presentation were not captured; evidence covers the real server RPC and production repository-resolution path.
  • Other nested mount depths and SSH login selection were not exercised.

Tests

Without the fix: vp test run src/server/ForgejoSourceControlProvider.test.ts failed on the repro assertion (expected undefined to equal 'one'). With the fix: vp test run src/server/ in packages/source-control-forgejo passed 5 files and 62 tests. vp run check:changed passed format, lint, knip, typecheck (11 packages) and tests (2 files).

    3. Approvability

      Verdict: Approved at 633db83

      Macroscope's review found this PR approvable — Forgejo HTTP(S) remotes now select the most specific matching server mount instead of becoming ambiguous when a root login also matches. Existing host checks, account tie-breaks, and SSH behavior remain unchanged, keeping the correction narrowly scoped.

      The Forgejo login matcher now narrows matches for non-SSH remotes with a path to logins with the longest parsed URL path. The test suite adds a same-host case for a repository URL under /gitea.

      For non-SSH remotes with a path, the matcher retains only logins with the longest parsed URL path. SSH and pathless remotes keep the prior matching behavior. The new test uses root and /gitea logins for one host and asserts that the remote under /gitea matches the login named one.

      The change makes a mounted-instance login win over a root login on the same host, but it does not cover every case. A root fj login can still shadow a mounted tea login, and a path copied from a different host can now pick a mount. Resolve these before merging, or explicitly accept them.

      Explanation

      The title states the main change: login matching for Forgejo now prefers the deepest-mounted login when a root login also matches. It follows the conventional commit format and matches the code change, which narrows matches to the longest login URL path for HTTP(S) remotes with a path.

      Full details: Linked Issues check

      Explanation

      The only linked coding requirement is [#35904]: an explicit HTTP(S) repository URL under a mounted Gitea base must select that mount's login, even when a root login exists on the same host. The whole-PR diff (merge base 025942d76a to head 633db83c45) changes matchForgejoLogin in packages/source-control-forgejo/src/server/ForgejoCli.ts. For non-SSH remotes with a non-empty path, it computes the path depth of each matching login URL with parseForgejoRemote and keeps only the logins at the maximum depth. A root login has depth 0 and a mounted login such as https://forge.example/gitea has depth 1. For remote https://forge.example/gitea/owner/repo.git, the root login is removed and the mounted login is the single match, so the existing single-match rule returns it. The existing filter still excludes mounts that do not prefix the remote path. SSH matching and empty-path host-only lookups keep the prior logic. A test assertion was added to 'does not choose a default Forgejo login across ambiguous SSH server ports' in ForgejoSourceControlProvider.test.ts for logins http://forgejo.local:4000 and http://forgejo.local:4000/gitea. The PR reports that this assertion failed on main and passed with the fix. The reported test run (5 files, 62 tests) was not re-run in this review. The pending real-app evidence section is not a coding requirement. The reproduction behavior in the issue is covered by the code path and the added test.

      Full details: Out of Scope Changes check

      Explanation

      The whole-PR diff contains two changes. The first is an 8-line change in matchForgejoLogin in ForgejoCli.ts that narrows matches by login URL path depth for HTTP(S) remotes with a path. It implements the objective of [#35904] directly. The second is a regression assertion in ForgejoSourceControlProvider.test.ts that supports that objective. No unrelated files or behavior changes were found in the reviewed diff. The PR description's documentation of reproduction and test results is not a code change. The 'Evidence' section is a placeholder and does not affect scope.

      Full details: Description check

      Explanation

      The description is detailed and covers the required template sections. Problem: matchForgejoLogin accepted a root login alongside a mounted-instance login, so it returned undefined and resolveRepository reported 'No matching Forgejo login'. Change: for HTTP(S) remotes with a path, matches are narrowed to the longest login URL path before the existing default rules run; SSH and host-only lookups are unchanged. Scope: it links the bug issue #35904. Verification: it reports a failing repro on main, a passing test run (5 files, 62 tests), and a check:changed run. It also states what was not exercised, such as released tea and live Gitea behavior. The template asks for a conventional commit title; the description does not show one, but the title is outside this description body. Before/after evidence for the real app is included as links and images. The author also says the real-app evidence is still being captured, per the PR objectives, which slightly conflicts with the evidence section.

      Compare mounted tea logins with root fj logins before selecting one.

      selectLogin(fjLogins) picks a matching root fj login before any tea login is read. The new longest-path filter then runs only over the fj list. A mounted tea login on the same host is never compared. For a mounted repository URL, the root login is used with the full mounted path, and repository resolution fails the owner/repository format check.

      Compare the eligible logins from both fj and tea, and choose the deepest matching mount. The selected login's CLI must still determine command and the authentication path.

      Do not carry the checkout path across a host change.

      When input.host differs from the checkout remote, resolveTarget replaces remote with the requested host and keeps remote?.path (ForgejoCli.ts:580-591). That path belongs to the other server. matchForgejoLogin then compares it with mount paths on the requested host. The path reuse predates this PR. Before this PR, the ambiguous result returned no login. The depth filter at line 207 now selects the deepest matching mount, so the request can target the wrong instance. The same foreign path also names the repository when input.repository is absent.

      Clear the path, or derive it from a remote on the requested host, only when the host changes. Keep the checkout path when the host matches. An unconditional clear also changes matchHostOnly and the repository path for bare owner/repo input, so scope the change to the replaced-host branch.

      Preserve .git in login mount paths.

      A login URL ending in /team.git is parsed as /team. For a root-instance remote such as /team/repo.git, the new filter then selects the /team.git login over the root login. API operations can target the wrong instance. Parse login base paths without removing the repository .git suffix. (raw.githubusercontent.com)
