# # 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.
