Robert Kaiser & the Mozilla CrashKill team
CrashKill
Mission: To improve stability of our products
Stability Factors
Reading The Tea Leaves
- Trends: crash rates, "explosiveness"
- Topcrash lists, crash ranks
- Correlations with code, website, 3rd-party software changes
- Specifics (browser vs. plugin, OSes, uptime, etc.)
- Pitfalls: rates and ADUs, ranks, signature changes
Areas of Focus
- Long tail
- 3rd-party issues, hangs, malware
- Analysis by component
- Startup crashes
- Mobile: fewer users, devices, Java, Android Symbol Sender
- Most crashes in core, not desktop/mobile-specific
Socorro
- crash-stats.mozilla.com
- Working closely with Socorro team to identify and prioritize front-end features that will help us diagnose crashes
Bugzilla Best Practice
- Add crash keyword
- If a regression, add regression keyword
- Add regressionwindow-wanted keyword
- Try finding regression window
- Try to correlate with push log
- If possible, find and add steps to reproduce
- Need crashing websites for work: add needURLs keyword
Community
- Keep community engaged by fixing their issues
- Community member Scoobidiver: >650 crash bugs filed
- We need more members of the community contributing in a more coordinated fashion
- From filing good bugs via regression hunting to trying to fix
- YOU can help!
