Build Changes (gps)

(Build changes of which engineers should be aware.)

  • WebIDL Windows clobber issues have hopefully been resolved!
    • Some fallout has been reported. File any issues and make sure things chain back to bug 928195.

    • The clobber issue related to touching .gypi files was fixed as part of this.
  • bug 950297 tracks merging js/src's build system with the main build system
    • This should make configure times much shorter on Windows

Upcoming Outages/Upgrades

(System outages/upgrades and tree closures that impact engineering.)

RelEng (catlee)
