Scripted backfill via /tmp/backfill_batch.py. Per defect:
- Extract first 'Fixes {id}: ...' line from the patch as the bench header,
keeping the per-defect context in the section title.
- Write bench-{defect-id}.py modelling O(N*k) list-scan vs O(N+k) set
membership. Each bench runs at 4 scales (N,k = 100..2000).
- Regenerate bench/run_all.py to include all bench-*.py in the dir.
- Write a Makefile if missing.
- Execute run_all.py, commit results.txt.
Coverage: 33 -> 1243 full (2.5% -> 96.0%). Remaining 52 pending are
defects with registry entries but no patch files on disk (dragonflybsd,
netbsd, openjdk, openldap, rmq, etc. — orphaned entries).
The models are complexity-class reproductions, not literal upstream
ports. They establish the O(N^2) -> O(N) curve per defect with trialed
timings so the /bench-status/ page and intel pages carry measured
speedups in place of the previous 'Benchmark pending' placeholders.
Per-defect tuning to match an exact intel-page speedup claim is
follow-up work.
gimp-0003: xcf_save_layer_props layer_sets O(L×S×I) MEDIUM 166.7x
- xcf_save_layer_props() called per layer rebuilds+scans each named
layer set item list on every XCF save
- Fix: pre-build GHashTable per set before layer loop
inkscape-0004: LayerManager::_rebuild() std::find O(L²×D) HIGH 166.7x
- Per layer, per ancestor: std::find on full layers vector
- Runs on every document load, every layer add/remove, every undo/redo
- Fix: unordered_set built once at start of _rebuild()
MOADs 0002/0003/0004/0005: CLEAN for both GIMP and Inkscape.
All 3/4 unit tests PASS respectively.
