# DESCRIPTION
|
||||
# This script is intended to be used in conjunction with "git bisect run"
|
||||
# in order to find regressions in build time, however it can also be used
|
||||
# independently. 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.
