fix(gl): pass the mirror temp path to git as an OS string by beardthelion · Pull Request #434 · Gitlawb/node

beardthelion · 2026-09-10T22:55:24Z

Summary

gl mirror converted the temp clone destination through mirror_path.to_str().unwrap(), so a TMPDIR containing non-UTF-8 bytes panicked before git started. The destination now goes to git as an OS-native Path.

Motivation & context

Closes #417

Kind of change

What changed

gl: the clone destination is passed via .arg(&mirror_path) instead of to_str().unwrap(), through a small clone_mirror helper so a test can drive the real argv.
Added a Unix-only regression test cloning into a mirror-\xffdest directory.

How a reviewer can verify

cargo test -p gl test_clone_mirror_non_utf8_dest

Panics on the old to_str().unwrap() form (revert-checked), passes with the Path arg.

Before you request review

Scope is one logical change; no unrelated churn
cargo test --workspace 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 (or 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

None: client-side argv construction only.

Notes for reviewers

Overlaps #376, which rewrites the same clone call to add a -- delimiter in front of the source. The fixes compose (OS-string destination + delimited source); whichever lands second needs a small rebase. The // allow-unbounded-git: marker documents that this spawn is the CLI's foreground clone, not a node request handler; it is the same spawn as before, relocated into the helper.

Summary by CodeRabbit

Bug Fixes
- Improved mirror cloning support for destinations with non-standard or non-UTF-8 paths.
- Preserved existing error handling when mirror cloning fails.
- Improved reliability when temporary directories use non-UTF-8 paths on Unix systems.
- Added coverage for cloning to non-UTF-8 destinations and temporary-directory configurations.

The clone destination went through to_str().unwrap(), so a TMPDIR with non-UTF-8 bytes panicked before git started. Pass the Path directly and add a Unix regression test cloning into a non-UTF-8 directory name. Closes #417

📝 Walkthrough

Walkthrough

The mirror flow now passes clone destinations as OS-native paths. Unix tests cover direct non-UTF-8 destinations and non-UTF-8 TMPDIR values without changing the parent environment.

Changes

Mirror path handling

Layer / File(s)	Summary
Native clone destination and regression coverage `crates/gl/src/mirror.rs`	`run` delegates cloning to `clone_mirror`. The helper passes the destination without UTF-8 conversion and preserves clone error handling. Unix tests cover direct and `TMPDIR`-derived non-UTF-8 paths.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Severity of issue fixed: Low

Merge Risk: ⚪ Minimal · up to 22724

Greptile Summary

This PR fixes gl mirror panics when the temporary clone destination contains non-UTF-8 bytes.

Extracts mirror cloning into a private helper.
Passes the destination to Git as an OS-native path.
Adds a Unix regression test using a non-UTF-8 destination.

Confidence Score: 5/5

The PR appears safe to merge and preserves existing clone behavior while eliminating the non-UTF-8 path panic.

The extracted helper retains the original command ordering and error handling, and the regression test directly verifies that the destination reaches Git as an OS-native argument.
