2.1 — Code Review Hardening + Regression Test Framework
Code Review Hardening + Regression Test Framework
What's New
Features & Improvements
- API Key clear/reset — cleanly clear a key in the Web UI instead of only overwriting it.
- Automated regression framework —
scripts/regression_runner.pyruns 9 scenarios concurrently (WeightedSemaphore, total weight ≤ 10), with incremental JSON + Markdown reports, endpoint verification, artifact checks, and resume / quick-verify /--cleanupmodes. - Longer keyframes timeout — video submission timeout raised to 180s for keyframes-heavy tasks to avoid spurious failures on slow renders.
Refactoring & Optimizations
- Security hardening (H1–H6) — API Key reads unified via
config.py(no hardcoded keys); upload path traversal blocked; shell injection removed (shell=True→ list args); CJK font fallback in subtitle overlay; moviepy log leakage silenced; JSON parse failure in screenwriter hardened with LLM retry fallback. - Robustness (M1–M10, L1–L8) — index/bounds safety, granular exception handling, path normalization, unified HTTP timeouts, task-state race fix, TTS file handle leak fix, i18n variable shadowing fix, dead-file cleanup, and the first automated unit test suite.
Bug Fixes
- UI bug: switching language no longer flips the API Key status display back to "not configured".
- Subtitle multi-line wrapping (dynamic
max_chars_per_line, CJK punctuation-break priority,method="caption"). - TTS edge-case error handling with automatic 2.5× volume boost.
- Concatenator single-video shortcut optimization + subtitle overlay failure degradation (non-blocking).
