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.pl: Process variables within variables

2024-03-15T14:50:51Z

Allow a variable to contain another variable. This will allow the ${shell } to have its command include variables. Signed-off-by: Steven Rostedt

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().

ktest.pl: Add RUN_TIMEOUT option with default unlimited

2023-02-20T16:52:27Z

There is a disconnect between the run_command function and the wait_for_input. The wait_for_input has a default timeout of 2 minutes. But if that happens, the run_command loop will exit out to the waitpid() of the executing command. This fails in that it no longer monitors the command, and also, the ssh to the test box can hang when its finished, as it's waiting for the pipe it's writing to to flush, but the loop that reads that pipe has already exited, leaving the command stuck, and the test hangs. Instead, make the default "wait_for_input" of the run_command infinite, and allow the user to override it if they want with a default timeout option "RUN_TIMEOUT". But this fixes the hang that happens when the pipe is full and the ssh session never exits.

ktest.pl: Give back console on Ctrt^C on monitor

2023-02-20T16:52:27Z

When monitoring the console output, the stdout is being redirected to do so. If Ctrl^C is hit during this mode, the stdout is not back to the console, the user does not see anything they type (no echo). Add "end_monitor" to the SIGINT interrupt handler to give back the console on Ctrl^C.

ktest.pl: Fix missing "end_monitor" when machine check fails

2023-02-20T16:52:27Z

In the "reboot" command, it does a check of the machine to see if it is still alive with a simple "ssh echo" command. If it fails, it will assume that a normal "ssh reboot" is not possible and force a power cycle. In this case, the "start_monitor" is executed, but the "end_monitor" is not, and this causes the screen will not be given back to the console. That is, after the test, a "reset" command needs to be performed, as "echo" is turned off.

ktest.pl: Add shell commands to variables

2022-12-09T04:23:05Z

Allow variables to execute shell commands. Note, these are processed when they are first seen while parsing the config file. This is useful if you have the same config file used for multiple hosts (as they may be in a git repository).

kest.pl: Fix grub2 menu handling for rebooting

2022-12-08T01:37:43Z

grub2 has submenus where to use grub-reboot, it requires: grub-reboot X>Y where X is the main index and Y is the submenu. Thus if you have: menuentry 'Debian GNU/Linux' --class debian --class gnu-linux ... [...] } submenu 'Advanced options for Debian GNU/Linux' $menuentry_id_option ... menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64' --class debian --class gnu-linux ... [...] } menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64 (recovery mode)' --class debian --class gnu-linux ... [...] } menuentry 'Debian GNU/Linux, with Linux test' --class debian --class gnu-linux ... [...] } And wanted to boot to the "Linux test" kernel, you need to run: # grub-reboot 1>2 As 1 is the second top menu (the submenu) and 2 is the third of the sub menu entries. Have the grub.cfg parsing for grub2 handle such cases.

ktest.pl minconfig: Unset configs instead of just removing them

2022-12-08T01:36:16Z

After a full run of a make_min_config test, I noticed there were a lot of CONFIGs still enabled that really should not be. Looking at them, I noticed they were all defined as "default y". The issue is that the test simple removes the config and re-runs make oldconfig, which enables it again because it is set to default 'y'. Instead, explicitly disable the config with writing "# CONFIG_FOO is not set" to the file to keep it from being set again. With this change, one of my box's minconfigs went from 768 configs set, down to 521 configs set.

bootconfig/tracing/ktest: Update ktest example for boot-time tracing

2021-08-16T15:39:51Z

Update ktest example for the boot-time tracing with histogram options. Note that since the histogram option uses "trace()" action instead of "EVENT()", this updates the matching pattern too.
