It cleans out the build output directories, runs a -# specified worker script (an example is test_build_time_worker.sh) under -# TIME(1), logs the results to TEST_LOGDIR (default /tmp) and returns a -# value telling "git bisect run" whether the build time is good (under -# the specified threshold) or bad (over it). There is also a tolerance -# option but it is not particularly useful as it only subtracts the -# tolerance from the given threshold and uses it as the actual threshold. -# -# It is also capable of taking a file listing git revision hashes to be -# test-applied to the repository in order to get past build failures that -# would otherwise cause certain revisions to have to be skipped; if a -# revision does not apply cleanly then the script assumes it does not -# need to be applied and ignores it. -# -# Please see the help output (syntax below) for some important setup -# instructions. -# -# AUTHORS -# Paul Eggleton <paul.eggleton@linux.intel.com> - - -syntax() { - echo "syntax: $0 <script> <time> <tolerance> [patchrevlist]" - echo "" - echo " script - worker script file (if in current dir, prefix with ./)" - echo " time - time threshold (in seconds, suffix m for minutes)" - echo " tolerance - tolerance (in seconds, suffix m for minutes or % for" - echo " percentage, can be 0)" - echo " patchrevlist - optional file listing revisions to apply as patches on top" - echo "" - echo "You must set TEST_BUILDDIR to point to a previously created build directory," - echo "however please note that this script will wipe out the TMPDIR defined in" - echo "TEST_BUILDDIR/conf/local.conf as part of its initial setup (as well as your" - echo "~/.ccache)" - echo "" - echo "To get rid of the sudo prompt, please add the following line to /etc/sudoers" - echo "(use 'visudo' to edit this; also it is assumed that the user you are running" - echo "as is a member of the 'wheel' group):" - echo "" - echo "%wheel ALL=(ALL) NOPASSWD: /sbin/sysctl -w vm.drop_caches=[1-3]" - echo "" - echo "Note: it is recommended that you disable crond and any other process that" - echo "may cause significant CPU or I/O usage during build performance tests." -} - -# Note - we exit with 250 here because that will tell git bisect run that -# something bad happened and stop -if [ "$1" = "" ] ; then - syntax - exit 250 -fi - -if [ "$2" = "" ] ; then - syntax - exit 250 -fi - -if [ "$3" = "" ] ; then - syntax - exit 250 -fi - -if !
