# This example shows the bisect tests (git bisect and config bisect)
#
# The config that includes this file may define a RUN_TEST
# variable that will tell this config what test to run.
# (what to set the TEST option to).
#
DEFAULTS IF NOT DEFINED RUN_TEST
# Requires that hackbench is in the PATH
RUN_TEST := ${SSH} hackbench 50
# Set TEST to 'bisect' to do a normal git bisect. You need
# to modify the options below to make it bisect the exact
# commits you are interested in.
#
TEST_START IF ${TEST} == bisect
TEST_TYPE = bisect
# You must set the commit that was considered good (git bisect good)
BISECT_GOOD = v3.3
# You must set the commit that was considered bad (git bisect bad)
BISECT_BAD = HEAD
# It's best to specify the branch to checkout before starting the bisect.
CHECKOUT = origin/master
# This can be build, boot, or test. Here we are doing a bisect
# that requires to run a test to know if the bisect was good or bad.
# The test should exit with 0 on good, non-zero for bad. But see
# the BISECT_RET_* options in samples.conf to override this.
BISECT_TYPE = test
TEST = ${RUN_TEST}
# It is usually a good idea to confirm that the GOOD and the BAD
# commits are truly good and bad respectively. Having BISECT_CHECK
# set to 1 will check both that the good commit works and the bad
# commit fails. If you only want to check one or the other,
# set BISECT_CHECK to 'good' or to 'bad'.
BISECT_CHECK = 1
#BISECT_CHECK = good
#BISECT_CHECK = bad
# Usually it's a good idea to specify the exact config you
# want to use throughout the entire bisect. Here we placed
# it in the directory we called ktest.pl from and named it
# 'config-bisect'.
MIN_CONFIG = ${THIS_DIR}/config-bisect
# By default, if we are doing a BISECT_TYPE = test run but the
# build or boot fails, ktest.pl will do a 'git bisect skip'.
# Uncomment the below option to make ktest stop testing on such
# an error.
#BISECT_SKIP = 0
# Now if you had BISECT_SKIP = 0 and the test fails, you can
# examine what happened and then do 'git bisect log > /tmp/replay'
# Set BISECT_REPLAY to /tmp/replay and ktest.pl will run the
# 'git bisect replay /tmp/replay' before continuing the bisect test.
#BISECT_REPLAY = /tmp/replay
# If you used BISECT_REPLAY after the bisect test failed, you may
# not want to continue the bisect on that commit that failed.
# By setting BISECT_START to a new commit. ktest.pl will checkout
# that commit after it has performed the 'git bisect replay' but
# before it continues running the bisect test.
#BISECT_START = 2545eb6198e7e1ec50daa0cfc64a4cdfecf24ec9
# Now if you don't trust ktest.pl to make the decisions for you, then
# set BISECT_MANUAL to 1. This will cause ktest.pl not to decide
# if the commit was good or bad. Instead, it will ask you to tell
# it if the current commit was good. In the mean time, you could
# take the result, load it on any machine you want. Run several tests,
# or whatever you feel like. Then, when you are happy, you can tell
# ktest if you think it was good or not and ktest.pl will continue
# the git bisect. You can even change what commit it is currently at.
#BISECT_MANUAL = 1
# One of the unique tests that ktest does is the config bisect.
# Currently (which hopefully will be fixed soon), the bad config
# must be a superset of the good config. This is because it only
# searches for a config that causes the target to fail. If the
# good config is not a subset of the bad config, or if the target
# fails because of a lack of a config, then it will not find
# the config for you.
TEST_START IF ${TEST} == config-bisect
TEST_TYPE = config_bisect
# set to build, boot, test
CONFIG_BISECT_TYPE = boot
# Set the config that is considered bad.
CONFIG_BISECT = ${THIS_DIR}/config-bad
# This config is optional. By default it uses the
# MIN_CONFIG as the good config.
CONFIG_BISECT_GOOD = ${THIS_DIR}/config-good
