Cause

CI on main (bbaad9c, run 42464902937) failed on windows-latest and windows-11-arm in tests::export_map_to_geotiff_draws_tile_layers_and_keeps_their_credits (from #1566):

panicked at crates\engine\src\tests.rs:33393:35:
called `Result::unwrap()` on an `Err` value: Os { code: 32, ... "The process cannot access the file because it is being used by another process." }

The test adds broken.mbtiles as a layer, so the session keeps the archive open, and then calls std::fs::remove_file on it. Linux and macOS allow deleting an open file. Windows does not.

Fix

The test already moves the layer's URL to gone.mbtiles, which never existed. That alone is the "archive gone" case, so the delete wasn't needed. The test now skips the delete and asserts that gone.mbtiles doesn't exist. The library code is unchanged.

Evidence

• The test passes locally on Linux. fmt and clippy are clean.
• Labelled ci:windows so the Windows jobs that failed on main run here.

The other two failures on bbaad9c were network flakes (a 504 from curl in Deploy web.rustgis.app, and "failed downloading release archive" in Docker images). They were rerun, not changed.

Summary by CodeRabbit

• Tests
  • Updated tile-layer export test coverage to use a URL pointing to a nonexistent tile-data file and verify that the file is absent, without deleting another file used during testing.
• User impact
  • No end-user-visible changes.

Walkthrough

The tile-layer export test now derives a nonexistent gone.mbtiles URL from the archive URL suffix, checks that the file is absent, and assigns the URL to the tile layer. It no longer deletes the open broken.mbtiles file.

Merge Risk: Minimal · up to 19b55

The test avoids deleting an open archive while preserving the missing-file scenario. No merge-blocking regression is established; the existing cleanup limitation remains separate follow-up work.

Full details: Description check

Explanation

The description follows the template. It has Summary, Testing, and Related issue sections. It explains the cause, the fix, and the evidence (local Linux pass, fmt and clippy clean, ci:windows label). The UI evidence section says 'No visible UI change.', which fits this test-only change. The Related issue section still has the placeholder comment and no issue reference. The description does not state the Testing commands explicitly in template form, but it does list verification steps.

No open file is swept away
The tile test marks the absent way

Code review

I found no bugs, security issues, or performance problems in this change. It is one test edit in crates/engine/src/tests.rs. I read it against the surrounding test and the tile reader. I did not compile or run the test.

• Bugs: None. The fix depends on the tile layer's url being what the draw opens. crates/map/src/tiles.rs:352-353 and :472-487 use self.url as the archive path, so rewriting the URL to gone.mbtiles is what makes the layer point at a missing file. Dropping the remove_file call therefore loses no coverage. The existing Severity::Warning / "empty" assertion still applies, and the new exists() precondition would catch a URL rewrite that didn't happen. Confidence: high.
• Security: None found.
• Performance: None found.
• Quality: One wording nit, grouped here rather than posted inline. The comment at line 13 says "Its file gone before the map is drawn", but nothing is deleted now: the layer points at a path that never existed. Something like "Its archive is missing: the layer points at one that isn't there" would be accurate. Left for the release quality pass. Confidence: high.
• AGENTS.md: The change adds no unwrap()/expect() to non-test code, and it adds no unsafe. The test-only unwrap() calls are allowed. Nothing else applies to this change.

Not verifiable from the checkout: the Windows lock explanation in the PR body, and the claim that the Windows jobs now pass. The PR's ci:windows run is the evidence for that. The PR body says it was labelled for that run; the label isn't in the staged metadata.

Earlier review threads: none exist on this PR, so none were left alone.

- Line 33395: Update the test’s `gone` path construction to replace only the
layer URL’s filename, rather than replacing every occurrence of “broken” in the
URL. Assert that this exact path does not exist, then assign its string form
back to `s.map_mut().tiles[0].url`.
- Around line 33394-33396: The test cleanup may run while a metadata read still
holds the archive, leaving it behind and causing later runs to fail. In the test
flow around the `gone` URL and `s.map_mut().tiles[0].url` assignment, ensure all
reads of `broken.mbtiles` have completed and released the file before removing
the fixture, then check and handle the removal result instead of ignoring
errors.
- Line 33396: Update the test around the `s.map_mut().tiles[0].url` assignment
to verify that archive export attempts to read the `gone` archive, rather than
passing solely because the tile is pending. Use an observable read attempt or
error that identifies the archive, preserving the test’s existing export
behavior.

Nit (test assertion, low impact): this checks dir.join("gone.mbtiles"), which is a separately built path, not the path the layer will read (gone, derived from url). They match today because url starts with dir, but the assertion should check the layer's own target. Checking the same path the layer uses:

Suggested change

	assert!(!dir.join("gone.mbtiles").exists());
	assert!(!std::path::Path::new(&url).with_file_name("gone.mbtiles").exists());

Confidence: medium. Only test-assertion precision; the rest of the change looks correct. The mbtiles reader opens read-only (crates/data/src/mbtiles.rs:308), so the missing-file path is what the export exercises.

Code review

Bugs: None found. The change swaps a file delete (which fails on Windows while the session holds the archive open) for pointing the layer at a gone.mbtiles that does not exist. The mbtiles reader opens archives read-only (crates/data/src/mbtiles.rs:308), so the export takes the missing-file path. The layer URL comes from layer.rs:1442 as a plain path, so strip_suffix("broken.mbtiles") matches on all platforms.

Security: None found. The change is test-only.

Performance: None found.

Quality:

• tests.rs:33397 (nit, confidence medium, posted inline): the non-existence assertion checks dir.join("gone.mbtiles"), not the path the layer will read. It matches today because the URL starts with dir, but the suggested form checks the layer's own target. This is a test-assertion precision point, so it may wait for the release quality pass.

AGENTS.md: Compliant. The change is test-only, no unwrap is added to non-test code, and the PR is labelled ci:windows to exercise the failing platform.

Earlier concerns left alone (already raised on this PR): 3 threads. The URL-rewrite concern is resolved in 19b5529. The cleanup remove_dir_all(&dir).ok() and the "either warning" assertion were answered by the author as left for the release quality pass. I did not re-raise them, since the code they point at has not changed.

Confidence in the overall verdict: high. I could not run the test here (no Bash access), so the Windows result is taken from the PR description and not verified.
