Mozilla improves Firefox stability on Linux

Summary

Gabriele Svelto describes how Mozilla reduces Linux crashes through better crash data, targeted fixes and work on frequent signatures. Mozilla uses Breakpad or Crashpad for crash reports. The work focused explicitly on Linux.

Ideas

  • Crash signatures group similar crashes across many installations.
  • Minidumps preserve registers and relevant memory areas for analysis.
  • The diversity of distributions and libraries makes uniform reproduction harder.
  • Prioritising by frequency directs work towards broad user impact.

Insights

  • Good telemetry turns scattered individual bugs into classes of bugs that can be worked on.
  • Platform-specific stability needs its own responsibility and measurable goals.
  • Crash rates show impact better than the number of closed tickets.

Recommendations

  • Submit reproducible crash reports with symbols and version data.
  • Watch error rates after releases separately per platform.

A small scheduler patch improves desktop responsiveness

LWN puts into context a much-discussed Linux patch that treats interactive loads more fairly against large build jobs through automatically formed task groups. Perceived speed depends more on latency spikes than on maximum total throughput. Small kernel changes can have big effects when they target a central resource decision.

htop explained

Pēteris Ņikiforovs explains every htop display and links it with Linux processes, the scheduler, memory management and procfs. /proc/loadavg provides load values, process counts and the most recently assigned PID. PID 1 traditionally belongs to the init process started at boot.
