[cbuildbot] Toolchain grouped builders are stepping on each other's Chrome builds. |
||||||||||||||||||||
Issue descriptionThe llvm-toolchain-group and gcc-toolchain-group both launch builds for 3 boards: peppy (the primary), daisy & x86-alex. The daisy & x86-alex BuildPackages phases always launch at the same clock time. Since May 7, one or both of them have been failing building chromeos-chrome...often a symptom of the failure is that it gets all the way to the install phase, at which point the out_<board>/Release directory is empty. Since there is a symbolic link ../c/Release that BOTH boards share to the same directory, they seem to be interfering with each other. The buildbots need to be updated to not do build_packages in the background.

The following revision refers to this bug: https://chromium.googlesource.com/chromiumos/chromite/+/3b4679e761844bef74acda77cae1cc1e995fedcf commit 3b4679e761844bef74acda77cae1cc1e995fedcf Author: Caroline Tice <cmtice@google.com> Date: Thu May 19 22:32:45 2016 [cbuildbot] Make grouped toolchain bots build_packages in foreground. This CL makes the gcc-toolchain-group and the llvm-toolchaing-group build their chromeos-chrome packages in the foreground rather than the background, to prevent multiple builds from interfering with each other. This is a quick fix, while we work on ungrouping the builders. BUG= chromium:613316 TEST=did run_tests in cbuildbot directory.
