[oe-commits] [bitbake] 10/16: runbuilds: process builds on SIGUSR1

[git at git.openembedded.org]

rpurdie pushed a commit to branch master-next
in repository bitbake.

commit 62d598cc5aa01d23f1e9284e9e926bd55b1d1878
Author: Ed Bartosh <ed.bartosh at linux.intel.com>

    runbuilds: process builds on SIGUSR1
    
    Run main processing function 'runbuild' only if SIGUSR1 is
    received. This signal is sent by Toaster when build status
    is changed (either started, cancelled or finished).
    
    This should stop continuous database polling as run_builds function
    will be called only when needed, i.e. after build status is changed.
