fix(server): recognize git remotes on partial clones

[ronak-ss]

Problem

In a partial clone (git clone --filter=blob:none), git appends the filter to the fetch line of git remote -v:

origin	https://github.com/pingdotgg/t3code.git (fetch) [blob:none]
origin	https://github.com/pingdotgg/t3code.git (push)

Four server parsers anchor the end of the line right after (fetch) / (push), so they drop that fetch line. What users see:

• Repository identity resolves to null, so PR listing and linked-PR sync skip the project (the symptom in [Bug]: Partial-clone remote annotations break repository detection and hide linked PRs #12764).
• With "Group by repository", the same repo shows up as two sidebar projects when one environment's checkout is a partial clone and the other is a normal clone. I hit this with a remote server checkout and a laptop checkout of the same repo.
• GitVcsDriver.listRemotes omits the remote, and ensureRemote adds a second remote instead of reusing origin.
• selectGitHubBaseRepository skips a partial-clone origin and picks a fork remote as the base repository.

Fixes #12764.

Change

The same change at each parse site: accept an optional trailing [<filter>] after the direction.

- /^(\S+)\s+(\S+)\s+\((fetch|push)\)$/
+ /^(\S+)\s+(\S+)\s+\((fetch|push)\)(?:\s+\[.*\])?$/

Sites: project/RepositoryIdentityResolver.ts, vcs/GitVcsDriver.ts, vcs/GitVcsDriverCore.ts, sourceControl/GitHubCli.ts.

The name, URL and direction captures are unchanged, and lines without an annotation parse exactly as before. The bracket body is .* because git prints the configured filter value verbatim (for example [sparse:oid=main:dir/a b]c]). The match is still anchored at the end of the line, so it can't bleed into the URL. A suffix without brackets, without the closing bracket, or without the space before the bracket is still rejected.

sourceControl/ForgejoCli.ts has the same pattern in its host lookup, and I left it unchanged on purpose. That lookup decides which scheme a stored fj token is sent over. For a partial clone it currently falls back to https://, which fails closed. Making partial clones match normal clones there would let an http:// remote receive the token over plain HTTP. Normal clones already do that, but whether they should is a separate decision. (This came up in review and is why the PR was narrowed.)

I kept per-site edits instead of a shared helper to keep the diff focused, since the copies have different shapes. Happy to consolidate them in a follow-up if you'd prefer.

Scope and approval

This is the triaged, accepted bug #12764, confirmed as a parser bug on current main in #12764 (comment).

#12776 by @vedprakash2302 fixed the three originally reported sites and was closed today with a request for fresh PRs against the V2 base. This PR is against current main (7ff2eabf, which includes #2829 and the new t3code/no-test-in-loop lint rule from #14921). It also covers GitHubCli.selectGitHubBaseRepository, which wasn't in the original report. #7499 changes only RepositoryIdentityResolver.

It's one underlying problem: parsing git remote -v lines that carry a partial-clone annotation. The change touches no credential path.

Verification

Focused tests next to each parser. Each one feeds synthetic git remote -v output, so the tests don't depend on the installed git printing the annotation (the caveat raised on #7499). There's also one real-git test that sets remote.origin.partialclonefilter=blob:none on a clone and checks it resolves to the same identity as a full clone.

New tests against the old parsers (source files reverted, tests kept):

 FAIL  src/project/RepositoryIdentityResolver.test.ts > RepositoryIdentityResolverLive > reads the remote from a fetch line ending in '(fetch) [blob:none]'
 FAIL  src/project/RepositoryIdentityResolver.test.ts > RepositoryIdentityResolverLive > resolves a partial clone the same as a full clone of the repository
 FAIL  src/sourceControl/GitHubCli.test.ts > selectGitHubBaseRepository > reads an origin whose fetch line carries a partial-clone filter
 FAIL  src/vcs/GitVcsDriver.test.ts > GitVcsDriver lists a remote whose fetch line ends in '(fetch) [sparse:oid=main:dir/a b]c]'
 FAIL  src/vcs/GitVcsDriverCore.test.ts > GitVcsDriver core integration > remote operations > ensureRemote reads an origin fetch line ending in '(fetch) [blob:none]'
 ... (12 failures in total, all of them the annotated-line cases)
      Tests  12 failed | 209 passed (221)

With the fix:

$ vp test run src/project/RepositoryIdentityResolver.test.ts src/vcs/GitVcsDriver.test.ts src/vcs/GitVcsDriverCore.test.ts src/sourceControl/GitHubCli.test.ts
 Test Files  4 passed (4)
      Tests  221 passed (221)

The plain-line and malformed-line cases pass both before and after.

Real partial clone, old vs new pattern:

"origin\thttps://github.com/pingdotgg/t3code.git (fetch) [blob:none]"
  old: REJECTED
  new: fetch https://github.com/pingdotgg/t3code.git
"origin\thttps://github.com/pingdotgg/t3code.git (push)"
  old: push https://github.com/pingdotgg/t3code.git
  new: push https://github.com/pingdotgg/t3code.git

vp fmt --check and vp lint (including t3code/no-test-in-loop) on the touched files and tsc --noEmit for apps/server are clean.

Approvability

Verdict: Approved at a0cb024

Macroscope's review found this PR approvable — This is a narrow parser bug fix that makes existing repository identity, remote reuse, and GitHub base-selection paths recognize partial-clone annotations. The production changes are small, preserve existing behavior for ordinary and malformed output, and are covered by focused tests.

Git remote parsers now accept trailing bracketed annotations after fetch or push markers. Tests cover partial-clone filters and malformed suffixes across remote listing, repository identity resolution, and source-control selection.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: juliusmarminge

Merge Risk: 🟡 Moderate · up to 4519e

An annotated HTTP remote may cause a request containing a stored Forgejo token to use plaintext transport. Resolve or explicitly accept that risk before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 4519e

This is a narrow compatibility change that preserves URL parsing and provider host checks. Partial clones now reuse existing remote configuration, including any separate push destination; that compatibility edge has not been verified end to end.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated effects concern configured checkout remotes, repository identity, provider targeting, and later branch publishing. A divergent push destination requires pre-existing remote configuration and a subsequent publishing action; the inspected annotation itself supplies no new command or credential authority.

Trust Boundaries and Controls

• observed — The parser discards annotation text rather than forwarding it to downstream operations. Remote reuse checks fetch identity, not push identity, and later push operations use the upstream remote name. This existing configuration-trust policy now also applies to annotated partial-clone remotes.

Hardening Proposals

• proposed — Make the intended treatment of divergent fetch and push destinations explicit for reused remotes, and validate that policy through PR-head materialization followed by publishing. This is a compatibility and authority-policy proposal, not a verified vulnerability.

Closing this. We fixed it on our side with a config change and aren't carrying T3 changes. The bug in #12764 is still real if someone wants to pick it up; the diff stays visible here.
