ktest: Ignore unset values of the minconfig in config_bisect

2011-06-02T15:57:57Z

By ignoring the unset values of the minconfig in deciding what to test in the config_bisect can cause the problem config from being tested too. Just do not test the configs that are set in the minconfig. Signed-off-by: Steven Rostedt

ktest: Fix result of rebooting the kernel

2011-06-02T15:57:56Z

The command that is called that reboots the kernel may fail but the return code is not passed back to the ktest.pl script. This is because a ';' is used between the two commands and if the second command fails, only the first command's return code is returned. Using a '&&' between the two commands fixes this.

ktest: Fix off-by-one in config bisect result

2011-06-02T15:57:41Z

Because in perl the array size returned by $#arr, is the last index and not the actually size of the array, we end the config bisect early, thinking there is only one config left when there are in fact two. Thus the result has a 50% chance of picking the correct config that caused the problem. Signed-off-by: Steven Rostedt

ktest: Allow options to be used by other options

2011-05-20T19:48:59Z

There are cases where one ktest option may be used within another ktest option. Allow them to be reused just like config variables but there are evaluated at time of test not config processing time. Thus having something like: MAKE_CMD = make ARCH=${ARCH} TEST_START ARCH = powerpc TEST_START ARCH = arm Will have the arch defined for each test iteration. Signed-off-by: Steven Rostedt

ktest: Create variables for the ktest config files

2011-05-20T19:26:26Z

I found that I constantly reuse information for each test case. It would be nice to just define a variable to reuse. For example I may have: TEST_START [...] TEST = ssh root@mybox /path/to/my/script TEST_START [...] TEST = ssh root@mybox /path/to/my/script [etc] The issue is, I may wont to change that script or one of the other fields. Then I need to update each line individually. With the addition of config variables (variables only used during parsing the config) we can simplify the config files. These variables can also be defined multiple times and each time the new value will overwrite the old value. The convention to use a config variable over a ktest option is to use := instead of =. Now we could do: USER := root TARGET := mybox TEST_SCRIPT := /path/to/my/script TEST_CASE := ${USER}@${TARGET} ${TEST_SCRIPT} TEST_START [...] TEST = ${TEST_CASE} TEST_START [...] TEST = ${TEST_CASE} [etc] Now we just need to update the variables at the top.

ktest: Reboot after each patchcheck run

2011-05-20T13:21:02Z

The patches being checked may not leave the kernel in a state that the next run will allow the new kernel to be copied to the machine. Reboot to a known good kernel before continuing to the next kernel to test. Added option PATCHCHECK_SLEEP_TIME for the max time to sleep between patchcheck reboots. Signed-off-by: Steven Rostedt

ktest: Reboot to good kernel after every bisect run

2011-05-20T13:16:29Z

Reboot after each bisect run regardless if the bisect passed or failed. The test may just be to boot the kernel and that kernel may not have a way to copy the next kerne to it. Reboot to a known good kernel after each bisect run. Signed-off-by: Steven Rostedt

ktest: If test failed due to timeout, print that

2011-05-20T13:14:35Z

If the test failed due to timeout for boot, print a message saying so. Otherwise the user will be confused to why their test just failed. Signed-off-by: Steven Rostedt

ktest: Fix post install command

2011-05-20T13:11:58Z

The command to run post install (for those that want initrds) was broken. Instead of doing a substitution for the $KERNEL_VERSION variable. It was replacing the entire command with nothing. Signed-off-by: Steven Rostedt
