Summary

Pass -- before positional path and URL arguments in git clone --mirror subprocess invocations so positional inputs cannot be interpreted as command-line flags.

Continues #463 (the commits are carried over unchanged; main was merged in as a separate commit, with the new clone invocation folded into the clone_mirror helper that landed on main since the branch was taken). The original fix is a recreation of #376.

Motivation & context

Without a -- delimiter, an option-shaped source (for example --upload-pack=...) passed to git clone --mirror is parsed as a git option rather than as the repository URL. A repository path or URL that begins with a hyphen is thus consumed silently and the wrong positional gets interpreted as the source.

Kind of change

• Bug fix
• Feature
• Security fix
• Docs
• Tests / CI
• Refactor (no behavior change)
• Breaking or protocol change (issue required first)

What changed

• crates/gitlawb-node/src/api/repos.rs: -- before positional arguments in fork_repo.
• crates/gitlawb-node/src/sync.rs: -- before positional arguments in clone_repo.
• crates/gl/src/mirror.rs: -- before positional arguments in gl mirror (merged into clone_mirror; the argv prefix lives in mirror_clone_args, which the regression test drives through real git).
• A regression test runs git clone --mirror -- --upload-pack=false <dest> and asserts git names the injected string as the repository rather than consuming it as an option.
• Maintainer commits on top: the main-merge resolution folded the delimiter into clone_mirror (keeping its Path-typed destination) and a clippy lifetime elision.

Fixes #374

How a reviewer can verify

cargo test -p gl mirror_clone
cargo test -p gitlawb-node --bin gitlawb-node --locked

On the un-delimited argv, git clone --mirror --upload-pack=false <dest> names <dest> as the repository (the option-shaped source is consumed); with the delimiter git names the source itself.

Before you request review

• Scope is one logical change; no unrelated churn
• cargo test -p gitlawb-node passes locally
• New behavior is covered by tests (required for fixes)
• cargo fmt --all and cargo clippy --workspace --all-targets -- -D warnings are clean
• Commit titles use Conventional Commits (feat(...), fix(...), docs(...))
• Docs / .env.example updated if behavior or config changed (N/A)
• Checked existing PRs so this isn't a duplicate

Protocol & signing impact

• Touches DID / did:key, Ed25519 / RFC 9421 signatures, UCAN, ref certs, or P2P wire formats
• Discussed in an issue before implementation
• Backward-compatible with existing nodes and previously signed history

Notes for reviewers

I ran the gitlawb-node and gl suites, not the whole workspace.

Summary by CodeRabbit

• Bug Fixes
  • Clone and fetch operations now correctly handle repository sources and remote URLs that begin with a hyphen, rather than interpreting them as Git options.
  • Mirror cloning, fork mirror cloning, and partial-clone modes also correctly handle option-shaped repository sources.
  • Warnings for decryption failures and recovered-blob mismatches now appear in the application’s warning output.

Walkthrough

Git clone and remote URL commands now use -- to separate options from positional values. Clone recovery warnings for decrypt failures and recovered-blob OID mismatches now use emit_warning.

Changes: Git argument delimiters

Layer / File(s)	Summary
Fork mirror-clone arguments crates/gitlawb-node/src/api/repos.rs	fork_repo uses a helper that places -- before the source and destination. A real-Git test checks an option-shaped source.
Sync clone and remote URL arguments crates/gitlawb-node/src/sync.rs	clone_repo and fetch_repo place -- before the remote URL. Tests check option-shaped remotes.
Partial and mirror clone arguments crates/gl/src/clone.rs, crates/gl/src/mirror.rs	Partial and mirror clone commands place -- before the source. Tests cover plain, branch, sparse, and mirror clone argument handling. Plain and branch clone tests also cover clones without withheld paths.

Clone warning output

Layer / File(s)	Summary
Clone warning emission crates/gl/src/clone.rs	Decrypt-failure and recovered-blob OID-mismatch warnings now use emit_warning instead of direct stderr writes.

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

Merge Risk: Low · up to 1b383

Partial-clone tests can fail under a translated Git locale. Running them with LC_ALL=C is a workaround; the change is otherwise mergeable with this limitation noted.

Full details: Title check

Explanation

The title names the main change: adding a -- delimiter before positional arguments in git clone --mirror invocations. It also names the affected areas (api, sync). It follows a Conventional Commits form and is specific enough for a reader scanning history. It is 75 characters, which is within a normal title length.

Full details: Description check

Explanation

The description follows the repository template. It has a Summary, Motivation and context with a linked issue (Fixes #374), Kind of change with checkboxes, What changed with the affected files, How a reviewer can verify with commands, the Before you request review checklist, Protocol and signing impact, and Notes for reviewers. The summary and motivation explain the problem and the fix clearly. The verification section gives concrete commands and expected behavior. Two checklist items are unchecked, and the Notes section adds that only the gitlawb-node and gl suites were run. The description is mostly complete.

Full details: Linked Issues check

Explanation

Issue #374 (direct, open) requires -- before positional path and URL arguments in git clone --mirror calls in fork_repo (repos.rs) and clone_repo (sync.rs). At the reviewed head 1b383c0, fork_clone_args returns ["clone", "--mirror", "--", source, dest], and fork_repo calls it. In clone_repo, args.push("--") runs before args.push(remote_url) and args.push(local_str), after the optional --filter=blob:limit=10g argument. Both required sites meet the requirement. Regression tests run real git with the option-shaped value --upload-pack=false: fork_clone_never_parses_the_source_as_a_git_option (repos.rs) and clone_never_parses_a_remote_as_a_git_option (sync.rs) assert that git names the value as the repository. The -- additions in fetch_repo (remote set-url, sync.rs), setup_partial_clone (clone.rs), and mirror_clone_args (mirror.rs) follow the same argv contract. The issue does not name these sites, so they do not change this result. Limitation: crates/gl/src/mirror.rs was not re-read in this review. Its result relies on the earlier review and the PR summary. No other call sites were audited.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 6 functions across 3 files. (1 skipped: 1 too large.)

Full details: Out of Scope Changes check

Explanation

The -- additions in fork_clone_args (repos.rs), clone_repo and fetch_repo remote set-url (sync.rs), and setup_partial_clone (clone.rs), with their tests, implement #374 or use the same option-injection class. However, the head diff for crates/gl/src/clone.rs still replaces three direct eprintln! warnings with emit_warning(&format!(...)). These are the decrypt-failure and OID-mismatch warnings in recover_encrypted_blobs, and the OID-mismatch warning in recover_from_arweave. These hunks add, remove, or move no git argument. They do not delimit positional arguments and do not relate to #374. The PR description's "What changed" section lists only three files and omits crates/gl/src/clone.rs and the fetch_repo remote set-url change in crates/gitlawb-node/src/sync.rs. Non-scope observation: the /// POST /api/v1/repos/:owner/:repo/fork doc comment now sits above fork_clone_args instead of fork_repo.

Resolution

Restore the original eprintln! calls in recover_encrypted_blobs and recover_from_arweave in crates/gl/src/clone.rs, or move that change to a separate pull request. Update the PR description to list every changed file, including crates/gl/src/clone.rs (setup_partial_clone delimiters and new tests) and the fetch_repo remote set-url change in crates/gitlawb-node/src/sync.rs. Move the POST fork route doc comment back above fork_repo.

Fix the locale-dependent assertion.

Git can translate this error message. For example, German Git uses Repository rather than repository, so this test fails in a German locale. (raw.githubusercontent.com) Set LC_ALL=C on the subprocess before checking its output.

Match git's stderr to the injected value, not its English wording.

The helper asserts an English, single-quoted message from git. Git can localize that message, so the assertion fails under a translated locale even when the -- delimiter is present. git_global passes the inherited locale through. The argv text that git_global includes in its error always contains the injected value, so a plain containment check on the whole error would pass without the delimiter. Checking only the text after failed: avoids both problems. Without --, git's stderr names the destination and omits the injected value, so the check still fails in all three modes.

Suggested fix

-    /// The assertion is on git's own words — `repository '<value>'`, single-quoted
-    /// — and not merely on the value appearing somewhere in the error. `git_global`
-    /// formats its failure as `git {args:?} failed: {stderr}`, so the injected
-    /// string is already present in the debug-printed argv whether or not the
-    /// delimiter is there; asserting on containment alone would pass with `--`
-    /// deleted. Undelimited, git consumes the value as an option, leaving the
-    /// destination as the only positional, and names *that* instead
-    /// (`repository '<dest>' does not exist`) — so this goes red without the fix.
+    /// The assertion checks only git's stderr, not the whole error. `git_global`
+    /// formats its failure as `git {args:?} failed: {stderr}`, so the injected
+    /// string is already in the debug-printed argv whether or not the delimiter
+    /// is there. Undelimited, git consumes the value as an option and names the
+    /// destination instead, so stderr no longer contains the value. Git may
+    /// translate its wording, so the check does not match English text.
     ///
     /// The payload carries no `:` or space: a colon would make git read the
     /// argument as an ssh-style `host:path` URL and report a hostname, which is a
     /// different parse.

Pin the locale in the mirror regression test.

The test spawns git without setting a locale. On a machine with a translated Git locale, Git can print a localized repository '...' does not exist message. The English substring assertion would then fail even though the delimiter works. Setting LC_ALL=C on this command keeps the argv and the regression coverage unchanged.

Suggested fix

         let out = Command::new("git")
+            .env("LC_ALL", "C")
             .args(mirror_clone_args(injected))

[cairn-intern]

Attribution fix request on the carried-over commits, on behalf of the author.

The first six commits on this branch (ec6d000, 912ddc0, 6d3b969, 49155cd, 7ab2b7e, 23e7a07, the old #463 head) are authored euxaristia <euxaristia@users.noreply.github.com>. That account was renamed from euxaristia to euxarist (same account, id 25621994), and since the rename the plain old-username no-reply address no longer resolves: GitHub shows no linked author for these commits, so they render as a bare name and do not count toward the author's profile.

Before this merges, could you rewrite the author and committer on those six commits to:

• Name: euxarist
• Email: 25621994+euxarist@users.noreply.github.com

The numbered no-reply form is tied to the account id, so the commits link to the author permanently, independent of any future rename. A git filter-repo --email-callback / --name-callback pass over the branch, or amending during the next rebase, both work; only those six commits need it, your two on top are fine as they are.

Thanks for moving the PR onto an upstream branch so the checks can run.

Posted by cairn-intern (Meta Muse) for euxarist.

🟢 Thanks for the contribution. I do not see any actionable issues from my review.

Merge readiness

• Branch vs main: Head includes merge of current main (0e5a1608); not stale relative to live target at review time.
• Supersedes prior work: Recreates closed #376 / #463 on a fresh branch; #539 is the active line for #374.
• GitHub merge state: mergeStateStatus is BLOCKED pending required review/approval (no human reviews yet; CodeRabbit was still in progress when metadata was captured). Not a code defect.
• Checks: PR Checks suite (fmt+clippy, test stable/beta, build, MSRV, etc.) succeeded on head; CodeQL Rust/Swift jobs may still complete asynchronously — reconfirm on merge if those are required protections.
• PR description hygiene (non-blocking): Maintainer “What changed” bullets focus on mirror clones; the same PR also documents and tests setup_partial_clone, fetch_repo set-url, and emit_warning routing. Worth aligning the human summary with the four-file diff so reviewers run the narrower never_parses filters (cargo test -p gl never_parses, cargo test -p gitlawb-node never_parses) called out in commits.

[beardthelion]

Attribution done at 1b383c0: the six carried commits now author and committer euxarist 25621994+euxarist@users.noreply.github.com (same trees, original timestamps, new SHAs). Also addressed at the same head: the stderr-assertion tests now pin LC_ALL=C so git's localized output cannot break them.
