fix: keep non-regular Git modes opaque by nia-sg-bot · Pull Request #42 · WildestAI/DiffGraph-CLI

nia-sg-bot · 2026-08-31T03:36:39Z

Summary

preserve exact symlink/type-change provenance while treating non-regular Git modes as opaque snapshots
avoid interpreting symlink targets ending in .py as Python source and emitting misleading empty topology
add staged type-change and unstaged symlink regression coverage

Part of #21

Validation

python3 -m pytest (147 passed)
git diff --check

Compatibility

This retains the versioned artifact shape and existing PARTIAL_ANALYSIS warning code. Consumers continue to receive the same provenance fields; non-regular modes now explicitly report that structural parsing and line counts were skipped.

Summary by CodeRabbit

Bug Fixes
- Symlinks and Git submodules are now recognized as non-regular files during local analysis.
- These entries are skipped instead of being incorrectly parsed as source code.
- Analyses now report partial results with clear warnings, without misleading symbols, relationships, or line counts.
- Submodule changes now preserve the associated commit identifiers across staged, unstaged, and commit-range analyses.

Walkthrough

The local diff analyzer treats symlinks and gitlinks as opaque snapshots. It skips source analysis, leaves language and line counts unset, preserves gitlink commit OIDs, and emits PARTIAL_ANALYSIS warnings. Tests cover staged, worktree, and commit-range cases.

Changes

Non-regular Git mode handling

Layer / File(s)	Summary
Detect modes and skip non-regular snapshots `diffgraph/structural.py`	The analyzer detects modes other than `100644` and `100755`, avoids gitlink blob reads, clears source metadata, and reports skipped analysis.
Resolve checked-out gitlink commits `diffgraph/git_snapshot.py`	The worktree reader resolves gitlink entries with `git rev-parse --verify HEAD^{commit}`, validates the OID, and reports malformed output.
Validate symlink and gitlink behavior `tests/test_structural.py`	Tests verify opaque symlink snapshots and gitlink commit provenance across staged, worktree, and commit-range analyses.

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

Merge Risk: ⚪ Minimal · up to 0e567

The PR treats symlinks and other non-regular Git objects as opaque snapshots while preserving existing provenance and warning fields. No actionable merge-blocking risk remains after normal checks and review.
