June 2025: Delivered stability improvements and maintainability enhancements for linuxdeepin/dde-file-manager. Key features delivered: Robust File Name Display and Watcher Stability — improved file list rendering by correctly using displayName when suffix comparisons fail and added null checks/cleanup for the file watcher (commits 1a46b191e46925ef1ddeac2ffdf4753f6722c5a7 and 32e6d05589f3f151273316964fbad23327a23ac6). Centralized Symlink Resolution in FileUtils — refactored symlink resolution into a single static method to ensure consistent handling across the codebase (commit 710f5ce46b314d3106775fcdd72df130a9c98062). Major bugs fixed: URL Handling Reliability in Job Notifications — avoided redundant percent-decoding by passing original QUrl objects to job creation and error handling, improving consistency of URL processing (commit 9ae60daacd3b1e98973030e71905949a12efbd1e). Overall impact and accomplishments: Increased UI reliability, reduced edge-case failures in file listings and notifications, and a cleaner, more maintainable codebase with reduced duplication. Technologies/skills demonstrated: Qt-based UI and async patterns (QFutureWatcher), robust URL handling with QUrl, static utility refactoring, code quality improvements, and disciplined commit hygiene. Business value: enhanced user experience with stable file listings, fewer issues in background job notifications, and easier future feature work due to centralized common logic.

Feb 1, 2025

February 2025: Delivered a critical bug fix in linuxdeepin/dde-file-manager to ensure file statistics reflect actual content by excluding symbolic link sizes. The change updates the core file size calculation in processFile to conditionally account for symbolic links, aligning reported sizes with user expectations and storage analytics. Commit 64ea7a4f1a4acd454f4c5a60fad0d3e95259cb32 documents the fix. Overall impact: improved accuracy of storage usage metrics and reduced potential user confusion, with no API changes. Technologies demonstrated: debugging, careful conditional logic, and maintainable code updates in a core statistics path.
