collect_range sent every gitlink line of git diff --raw to expand_gitlink,
including one whose destination is no longer a gitlink: a submodule removed,
or replaced by files tracked at the same path, as when a repository is merged
into its superproject with its history. expand_gitlink then demanded a
checkout of a submodule that no longer exists and the push was refused, exit
2, naming it -- with no way to satisfy the remedy it printed.

Only a pointer that is still a gitlink at the end of the range has a tree to
read. One deleted in the range is skipped; what stands at the path now is in
the name-only diff as files. That diff also takes T now, so a gitlink or
symlink that became a regular file is scanned as one.

Two cases, both failing before this change: a submodule folded into the
superproject has its replacing lockfile scanned, and a submodule removed
outright needs no checkout.

Found by

A superproject merging one of its submodule repositories in with its history: the merge deletes the docs gitlink and tracks the same files at docs/, and uphold supply-chain at pre-push refused with "the submodule docs moved in this range and is not checked out". Present on main at v1.38.0.

Verified

• cargo test --test supply_chain_cli submodule: 5 passed; the two new cases fail on main.
• Commit and pre-push hooks green.

Summary by CodeRabbit

• Bug Fixes
  • Changed file types are now included when identifying files in a range.
  • Removed or replaced submodules no longer trigger “not checked out” messages during range checks.

Walkthrough

collect_range now includes type-changed paths and expands raw-diff entries only when the destination mode is a gitlink. New CLI tests cover submodule replacement with tracked files and outright submodule removal.

Changed-path and submodule selection src/supply.rs, tests/supply_chain_cli.rs	collect_range includes type-changed paths and expands only destination gitlinks. CLI tests check that replacing or removing a submodule does not produce a “not checked out” message.

The range collector correctly handles removed and replaced submodules. Mergeable with bounded follow-up to strengthen tests for type changes and scanner invocation; no current behavioral failure was established.

uphold-review

Walkthrough

The supply-chain pre-push scope builder, collect_range in src/supply.rs, used to send every gitlink line of git diff --raw to expand_gitlink. That included a gitlink deleted in the pushed range. A deleted gitlink has no checkout, so the push was refused with a remedy nobody could carry out.

The change makes three edits:

• It expands a raw-diff entry only when the path is still a gitlink at the end of the range (destination mode 160000). It no longer matches on either mode.
• It adds T (type change) to the name-only diff filter. A path that turned from a gitlink or symlink into a regular file is now scanned as a file.
• It adds two CLI tests: a submodule folded into the superproject has its replacing lockfile scanned, and a submodule removed outright needs no checkout.

I checked the change against the review document's principles. It explicitly handles a state the old code got wrong, keeps the existing refusal for a submodule that still exists and is not checked out, and covers both new paths with tests. A file replaced by a gitlink still goes to expand_gitlink, as it did before. None of the records gets a concrete reason to be violated, so I'm reporting no violations.

Changes

File	Change
src/supply.rs	collect_range now expands a raw-diff entry only when its destination mode is still a gitlink (160000), so a submodule deleted or replaced by files in the range is skipped instead of demanding a checkout. The name-only diff filter gains T, so a path whose type changed into a regular file is collected.
tests/supply_chain_cli.rs	Adds two tests: a submodule replaced by tracked files at the same path has its lockfile scanned with no checkout demanded, and a submodule removed outright passes with no checkout demanded.

src/supply.rs: 1

730-730: Trivial · Functional Correctness · Quick win

Add a range-scan test for a symlink that becomes a regular uv.lock.

The ACMRT filter at src/supply.rs:730 selects T changes, so a path that changes from symlink to regular file is listed for scanning. No test in tests/supply_chain_cli.rs produces a T status. Removing T would leave the suite passing while such a uv.lock is no longer scanned.

Add a range test that commits a symlink named uv.lock, then replaces it in place with a regular file in the pushed range. Assert that the regular uv.lock is scanned for that range. Do not use git rm --cached for the replacement. That sequence produces D and A statuses, not T, which is the pattern the existing submodule tests use.

Add a range-scan test for a `uv.lock` that changes from a symlink to a regular
file, and assert the regular file is scanned. Exercise the in-place replacement
so Git reports a `T` status; do not use `git rm --cached`, which produces
separate delete and add statuses.

1420-1420: Trivial · Maintainability & Code Quality · Quick win

Assert that the replacement test's scan receives sub/uv.lock.

The replacement test checks only the printed count, 1 lockfile(s) in this range. The count and the -L scan arguments come from the same locks list, so current behavior is correct. A regression that prints the count but does not pass the lockfile to osv-scanner can still pass this test. The earlier submodule test in this file checks the stub journal for each scanned path. Add the same check here.

🧪 Suggested test assertion

     assert!(said.contains("1 lockfile(s) in this range"), "{said}");
+    let ran = journal(&root);
+    assert!(ran.contains("sub/uv.lock]"), "{ran}");

Review comment at @tests/supply_chain_cli.rs at line 1420:
Update the replacement test containing the lockfile-count assertion to also
verify that the scanner journal records `sub/uv.lock`, so the test checks that
the lockfile is actually scanned.

Assert that the removal test runs no scanner.

The removal test checks only the exit code and the absence of "not checked out". If the selection included sub/uv.lock, the zero-exit osv-scanner stub would still return success, and the test would still pass. Assert that the stub journal records no osv-scanner run.

Suggested fix

     let said = text(&output);
     assert!(!said.contains("not checked out"), "{said}");
+    let log = journal(&root);
+    assert!(!log.contains("osv-scanner"), "{log}");
