Conversation
💡 What: Replace manual byte-by-byte iteration with bytes.translate() and bytes.find() when decoding yEnc data. 🎯 Why: The original python-level iteration over bytearrays was very slow for large NZB body strings. Utilizing C-backed builtin methods eliminates loop overhead. 📊 Impact: Improves decoding speed by >10x during deep-check yEnc body validation phase. 🔬 Measurement: Using a simple test script decoding 1000 yEnc lines, runtime decreased from ~0.33s to ~0.02s.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |
