Build Changes (gps)

(Build changes of which engineers should be aware.)

  • bug 904979 creates a divergence between default build options for local and official/release builds with the goal of making local builds faster at the expense of not being exactly like release builds.
  • Many users are experiencing issues loading mozconfigs or mozinfo.json, especially with mach mochitest commands. If you encounter an error, please file it under Core :: Build Config as a P1 and assign to gps@mozilla.com.
  • glandium and gps have been making many changes to make rules and tier traversal. Be on the lookout for oddities/regressions and report them immediately.
  • |mach build| records resource usage of builds bug 883209 - will roll out to automation once it has proved itself

Upcoming Outages/Upgrades
