Check the build-time.log and monitor for modifications to determine if the build has hung for at most #mins before killing the build and reporting a timeout. This allows infinite sized builds as we get to a lower number of autobr fails. Less failures means we start to see false timeout failures when we hit the boundary of the old MAX_DURATION ~8hrs. Signed-off-by: Matthew Weber <matthew.weber@rockwellcollins.com> -- Change Log v2 -> v3 - Adjust hung timeout to 2hrs as minic, gst-ffmpeg and qt5webkit could go beyond 60mins on a minimal 2-4core machine while processing a single build step written v1->v2 [Thomas P. - Use mtime vs reading file - Use datetime for hung delta check - Removed camel case - Added hung build event to sync hand-off back to main thread --- scripts/autobuild-run | 58 +++++++++++++++++++++++++++++++++++++++++++-------- 1 file changed, 49 insertions(+), 9 deletions(-)
