ktest: Fix Test Failures Due to Missing LOG_FILE Directories

2025-03-27T13:34:00Z

Handle missing parent directories for LOG_FILE path to prevent test failures. If the parent directories don't exist, create them to ensure the tests proceed successfully.

ktest.pl: Check kernelrelease return in get_version

2024-12-18T21:51:38Z

In the case of a test that uses the special option ${KERNEL_VERSION} in one of its settings but has no configuration available in ${OUTPUT_DIR}, for example if it's a new empty directory, then the `make kernelrelease` call will fail and the subroutine will chomp an empty string, silently. Fix that by adding an empty configuration and retrying.

ktest.pl: Avoid false positives with grub2 skip regex

2024-09-04T19:06:28Z

Some distros have grub2 config files with the lines if [ x"${feature_menuentry_id}" = xy ]; then menuentry_id_option="--id" else menuentry_id_option="" fi which match the skip regex defined for grub2 in get_grub_index(): $skip = '^\s*menuentry'; These false positives cause the grub number to be higher than it should be, and the wrong kernel can end up booting. Grub documents the menuentry command with whitespace between it and the title, so make the skip regex reflect this.

ktest.pl: Always warn on build warnings

2024-09-04T19:05:48Z

If a warning happens at build, give a warning at the end: Build time: 1 minute 40 seconds Install time: 17 seconds Reboot time: 25 seconds *** WARNING found in build: 1 *** ******************************************* ******************************************* KTEST RESULT: TEST 1 SUCCESS!!!! ** ******************************************* ******************************************* This way, even if the test isn't made to fail on warnings during the build, a message is still displayed that warnings were found.

ktest: force $buildonly = 1 for 'make_warnings_file' test type

2024-03-15T16:36:19Z

The test type "make_warnings_file" should have no mandatory configuration parameters other than the ones required by the "build" test type, because its purpose is to create a file with build warnings that may or may not be used by other subsequent tests. Currently, the only way to use it as a stand-alone test is by setting POWER_CYCLE, CONSOLE, SSH_USER, BUILD_TARGET, TARGET_IMAGE, REBOOT_TYPE and GRUB_MENU.

ktest: Restore stty setting at first in dodie

2023-02-20T16:52:27Z

The do_send_email() will call die before restoring stty if sendmail setting is not correct or sendmail is not installed. It is safer to restore it in the beginning of dodie().
