refactor: split backend into api/core/services/schemas, harden security + fd pressure, add searchable language picker, fix segment fragmentation
...
Backend:
- Split monolithic main.py into backend/{api/routers,core,schemas,services}
- core/db.py: allowlist-gated migrations, db_conn context manager (kills SQL injection on ALTER)
- core/tasks.py: lock-guarded listener add/remove/push, snapshot-before-iterate
- services/ffmpeg_utils.py: run_ffmpeg helper with concurrency semaphore, EAGAIN retry, guaranteed reap
- services/segmentation.py: Bengali/CJK/Arabic punctuation, ultra-short tier, stitch_adjacent_shorts,
bounded-loop merge; public clean_up_segments API
- services/model_manager.py: robust lock.locked() handling
- api/routers/dub_core.py: job_id traversal guard, thread-safe _active_procs, timeouts on ffmpeg/demucs,
POST /dub/cleanup-segments endpoint
- api/routers/dub_export.py: guarded SSE listener remove, ffmpeg timeouts via run_ffmpeg
- api/routers/exports.py: destination_path validation, safe source resolver, subprocess list-form
- api/routers/generation.py: contextlib.suppress on tempfile cleanup, db_conn usage, safe output-path helper
- api/routers/system.py: try/finally tmp cleanup, subprocess timeouts
- schemas/requests.py: TranslateSegment.id int->str to match hex segment IDs
- main.py: threading.Lock around crash log writes
Frontend:
- components/SearchableSelect.jsx: popover combobox with search, keyboard nav, popular+recent pins, 200-item cap
- App.jsx: wire SearchableSelect for dub language / ISO code / voice-gen language; Clean Up segments button;
fix blob URL leak (object-shaped prev in setter, unmount cleanup via ref)
- components/WaveformTimeline.jsx: explicit <video> detach instead of innerHTML='' to release decoder
- index.css: ss-* combobox styles matching Gruvbox theme
Tests:
- tests/test_segmentation.py (26 cases), test_dub_transcribe.py, test_dub_export_unique.py, conftest.py
Chore:
- .gitignore: exclude omnivoice.zip, /research/ reference clones
- Remove tracked stray root test scripts + crash_log.txt
