When --build_dir is provided use it and do not pollute source directory which even can be mounted over network or read-only. Signed-off-by: Andy Shevchenko Reviewed-by: Brendan Higgins Tested-by: Brendan Higgins Signed-off-by: Shuah Khan

kunit: Fix kunit.py parse subcommand (use null build_dir)

2020-11-10T20:09:15Z

When JSON support was added in [1], the KunitParseRequest tuple was updated to contain a 'build_dir' field, but kunit.py parse doesn't accept --build_dir as an option. The code nevertheless tried to access it, resulting in this error: AttributeError: 'Namespace' object has no attribute 'build_dir' Given that the parser only uses the build_dir variable to set the 'build_environment' json field, we set it to None (which gives the JSON 'null') for now. Ultimately, we probably do want to be able to set this, but since it's new functionality which (for the parse subcommand) never worked, this is the quickest way of getting it back up and running.

kunit: tool: handle when .kunit exists but .kunitconfig does not

2020-10-02T16:24:19Z

Right now .kunitconfig and the build dir are automatically created if the build dir does not exists; however, if the build dir is present and .kunitconfig is not, kunit_tool will crash. Fix this by checking for both the build dir as well as the .kunitconfig. NOTE: This depends on commit 5578d008d9e0 ("kunit: tool: fix running kunit_tool from outside kernel tree") Link: https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/commit/?id=5578d008d9e06bb531fb3e62dd17096d9fd9c853 Signed-off-by: Brendan Higgins Signed-off-by: Shuah Khan

kunit: tool: allow generating test results in JSON

2020-08-31T21:40:00Z

Add a --json flag, which when specified generates JSON formatted test results conforming to the KernelCI API test_group spec[1]. The user can use the new flag to specify a filename to print the json formatted results to.

kunit: tool: fix improper treatment of file location

2020-07-17T20:17:49Z

Commit 01397e822af4 ("kunit: Fix TabError, remove defconfig code and handle when there is no kunitconfig") and commit 45ba7a893ad8 ("kunit: kunit_tool: Separate out config/build/exec/parse") introduced two closely related issues which built off of each other: they excessively created the build directory when not present and modified a constant (constants in Python only exist by convention). Together these issues broken a number of unit tests for KUnit tool, so fix them. Fixed up commit log to fic checkpatch commit description style error.

kunit: kunit_tool: Fix invalid result when build fails

2020-06-26T20:29:31Z

When separating out different phases of running tests[1] (build/exec/parse/etc), the format of the KunitResult tuple changed (adding an elapsed_time variable). This is not populated during a build failure, causing kunit.py to crash. This fixes [1] to probably populate the result variable, causing a failing build to be reported properly.
