[GIT PULL] ktest: Updates for 7.1

[Steven Rostedt]

Linus,

ktest updates for v7.1:

- Fix undef warning when WARNINGS_FILE is unset

  The check_buildlog() references WARNINGS_FILE even when it's not set. Perl
  triggers a warning in this case. Check if the WARNINGS_FILE is defined
  before checking if the file it represents exists.

- Fix how LOG_FILE is resolved

  LOG_FILE is expanded immediately after the config file is parsed. If
  LOG_FILE depends on variables from the tests it will use stale values
  instead of using the test variables. Have LOG_FILE also resolve test
  variables.

- Treat a undefined self reference variable as empty

  Variables can recursively include itself for appending. Currently, if the
  references itself and it is not defined, it leaves the variable in the
  define: "VAR = ${VAR} foo" keeps the ${VAR} around. Have it removed
  instead.

- Fix clearing of variables per tests

  If a variable has a defined default, a test can not clear it by assigning
  the variable to empty. Fix this by clearing the variable for a test when
  the test config has that variable assigned to nothing.

- Fix run_command() to catch stderr in the shell command parsing

  Switch to Perl list form open to use "sh -c" wrapper to run shell commands
  to have the log file catch shell parsing errors.

- Fix console output during reboot cycle

  The POWER_CYCLE callback during reboot() can miss output from the next
  boot making ktest miss the boot string it was waiting for.

- Add PRE_KTEST_DIE for PRE_KTEST failures

  If the command for PRE_KTEST fails, ktest does not fail (this was by
  design as this command was used to add patches that may or may not apply).
  Add PRE_KTEST_DIE value to force ktest to fail if PRE_KTEST fails.

- Run POST_KTEST hooks on failure and cancellation

  PRE_KTEST always runs before a ktest test, have POST_KTEST always run
  after a test even if the test fails or is cancelled to do the teardown of
  PRE_KTEST.

-- Add a --dry-run mode

  Add --dry-run to parse the config, print the results and exit without
  running any of the tests.

-- Store failures from the dodie() path as well

  The STORE_FAILURES saves the logs on failure, but there's failure paths
  that miss storing. Perform STORE_FAILURES in dodie() to capture these
  failures too.

[GIT PULL] ktest: Updates for 7.1

[Steven Rostedt]

Linus,

ktest updates for v7.1:

- Fix month in date timestamp used to create failure directories

  On failure, a directory is created to store the logs and config file to
  analyze the failure. The Perl function localtime is used to create the
  data timestamp of the directory. The month passed back from that
  function starts at 0 and not 1, but the timestamp used does not account
  for that. Thus for April 20, 2026, the timestamp of 20260320 is used,
  instead of 20260420.

- Save the logfile to the failure directory

  Just the test log is saved to the directory on failure, but there's
  useful information in the full logfile that can be helpful to analyzing
  the failure. Save the logfile as well.
