[written by AI]

Part of PickNikRobotics/moveit_pro#22309 (second of three stacked PRs; based on main because this repo's integration CI pulls an image named after the base branch, so the diff includes #901's commit until #901 merges: review the second commit; #903 is the sibling).

Motivation

Refreshing a vendored copy is a manual sparse-checkout-and-reapply: fetch upstream, copy the retained folders in, and re-do every local edit by hand from memory. For phoebe_ws that is twelve edited files, and every phoebe change now costs a second step to land here.

Brief description

bin/vendored_dependency.py update <source> [--to COMMIT] refreshes one vendored source. The local patch is recoverable because the manifest pins the old commit, which is what keeps this small:

  1. In a temporary checkout, fetch the pinned upstream branch as a promisor remote (blob:none, so only the retained files are ever downloaded) and sparse-checkout the retained paths at the old pin.
  2. Overlay the vendored tree onto it and commit the result. That commit is the local patch, edits and prunes included.
  3. Check out the target commit (default: the head of the pinned branch) and cherry-pick the local patch with --no-commit. This is a real three-way merge with every blob available, which git apply -3 against the workspace could not offer because the old upstream blobs are not in this repo.
  4. A file we pruned that upstream later modified surfaces as a modify/delete conflict. The pruning was deliberate, so the script keeps it deleted. Any other conflict is copied back with ordinary markers and the script stops with the file list.
  5. Copy the retained paths back, bump commit: in UPSTREAM.yaml, reset the temp checkout to the pristine new tree, and run the validator's validate_upstream_snapshot against it. That reports omits a modified upstream path / lists an unchanged upstream path as modified without a second fetch.

The script refuses to start when vendored files are unsmudged Git LFS pointers, since the overlay would otherwise commit pointer text as the local edit, and refuses to finish if the copy-back produced any, because the validator compares LFS pointers by content hash and cannot tell a pointer from the file it stands for. The temp checkout ignores the developer's signing and hook configuration, so a global commit.gpgsign or core.hooksPath cannot break the synthetic commit, and git prompts are disabled so a private upstream fails fast instead of hanging on a hidden password prompt. Every early exit after the copy-back names the git restore command that discards the half-done refresh. The script never commits to this repository; the last line on success tells the user to review git status, build the consuming configs, and commit.

Dry runs on the current pins: ros2_kortex and phoebe_ws refresh cleanly and pass the validator. franka_config (89 commits behind) stops on conflicts in CMakeLists.txt and package.xml and warns that two vendored_paths no longer exist upstream, which is the case a human has to decide.

Tests build a real two-commit upstream repo under tmp_path and exercise: a clean refresh that preserves a local edit and a prune, a pristine copy that only moves the pin, --to an explicit commit and the already-current no-op, an unresolvable and an option-like --to, a conflict leaving markers and the recovery hint, a stale ledger when upstream adopts a local edit, a vendored path upstream removed, a manifest whose commit: line the rewrite could not match, an unknown source name, source lookup by name and by path, a fetch failure, both LFS-pointer refusals, and the git-failure, timeout, and copy-failure handlers.

Deferred from review: update does not apply the validator's UPSTREAM_MAX_SNAPSHOT_* size caps before materializing the new tree. Those caps protect CI from a hostile upstream; update is a developer-invoked command against an upstream the developer chose, and the same tree lands in their working copy either way.

Walkthrough

The pull request adds a vendored dependency CLI with status and update commands. It validates manifests, reports GitHub drift, refreshes pinned sources while preserving local changes, expands tests, updates CI, and documents the workflow.

Changes

Vendored dependency management

Layer / File(s) Summary
Drift status reporting
.github/workflows/ci.yaml, bin/vendored_dependency.py, bin/tests/test_vendored_dependency.py
The status command discovers manifests, queries GitHub compare data, renders results, and writes GitHub Actions outputs. CI runs the full bin/tests suite and publishes drift results.
Dependency refresh workflow
bin/vendored_dependency.py
The update command validates sources, fetches upstream commits, reapplies local changes, copies refreshed content, updates pins, checks ledgers, and reports failures or conflicts.
Refresh validation and guidance
bin/tests/test_vendored_dependency.py, README.md
Tests cover refresh behavior, conflicts, invalid state, Git and filesystem failures, and manifest resolution. The README documents commands, recovery, conflict handling, and validation steps.

Merge Risk: 🔵 Low · up to 1a9b4

The vendored dependency refresh workflow is broadly covered, but paths containing spaces may be processed incorrectly and path-based source selection may fail from a symlinked repository root. These edge cases should be fixed or explicitly accepted before relying on the command for affected dependencies.

The PR adds permission and authentication behavior.

219-228: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Resolve both sides of the path comparison.

candidate.resolve() is resolved, but manifest_path.parent and manifest_path are not. If any component of REPOSITORY_ROOT is a symlink, the two paths differ and the path form of source fails with no vendored source named .... This happens on macOS, where /tmp links to /private/tmp, and on symlinked home or workspace directories. The name form still works, so the failure is confusing rather than fatal.

Resolve the manifest path once per candidate and compare resolved paths.

♻️ Proposed fix
     candidate = Path(source)
     for manifest_path in manifests:
         if manifest_path.parent.name == source:
             return manifest_path
-        if candidate.is_absolute() and candidate.resolve() in (
-            manifest_path.parent,

436-453: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Parse Git path lists with -z instead of .stdout.split().

--name-only prints one path per line. .split() breaks on any whitespace, so a path that contains a space becomes several fragments. Two failures follow: the path in pruned test misclassifies the path, and git rm --quiet --force -- <fragment> then fails with CalledProcessError. The user sees git rm --quiet failed instead of the real conflict state. -z also turns off Git path quoting for non-ASCII names.

The same pattern appears at line 425 for the re-applied file count.

♻️ Proposed fix
-    conflicts = git(checkout, "diff", "--name-only", "--diff-filter=U").stdout.split()
+    conflicts = [
+        path

Add bin/vendored_dependency.py update <source> [--to COMMIT]. It rebuilds the local patch by diffing the vendored tree against the pinned upstream commit, re-vendors the retained paths at the new commit, re-applies that patch as a three-way merge (keeping locally pruned files deleted), bumps commit: in UPSTREAM.yaml, and re-runs the ledger check against the new upstream tree. Conflicts are left as ordinary markers.
