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

Approvability#
Verdict: Approved at
633db83Macroscope'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 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.

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.

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.
