From 84570842d373d67f01d4531f2cccd770d2690e38 Mon Sep 17 00:00:00 2001 From: DhanushSantosh Date: Thu, 5 Feb 2026 10:42:56 +0530 Subject: [PATCH] fix: resolve three critical bugs from GitHub issue tracker Fix #684: Prevent Windows reserved filename creation - Add sanitizeFilename() utility to detect and prefix Windows reserved names (NUL, CON, PRN, AUX, COM1-9, LPT1-9) - Apply sanitization to save-image route to prevent "nul" file creation - Add 23 comprehensive tests for filename sanitization edge cases Fix #576: Detect actual dev server port from output - Parse stdout/stderr for real server URLs (Vite, Next.js, generic formats) - Update server URL when detected instead of using allocated PORT - Emit dev-server:url-detected event for frontend updates - Add 6 tests for URL detection patterns Fix #193: Commit only feature-specific changes - Change from 'git add -A' to branch-aware file staging - Use git diff to find files changed on feature branch only - Prevent committing unrelated changes from other features - Maintain backward compatibility with main branch workflow All fixes include comprehensive tests and maintain backward compatibility.
