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

2023-01-07T11:07:35+00:00

commit ef784eebb56425eed6e9b16e7d47e5c00dcf9c38 upstream.

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.

tweewide: Fix most Shebang lines

2021-06-03T06:23:27+00:00

commit c25ce589dca10d64dde139ae093abc258a32869c upstream.

Change every shebang which does not need an argument to use /usr/bin/env.
This is needed as not every distro has everything under /usr/bin,
sometimes not even bash.

ktest: Fix child exit code processing

2017-03-15T02:02:45+00:00

commit 32677207dcc5e594254b7fb4fb2352b1755b1d5b upstream.

The child_exit errno needs to be shifted by 8 bits to compare against the
return values for the bisect variables.

ktest: Place quotes around item variable

2015-02-03T20:45:13+00:00

Seems that some of the new console logic causes doprint to possibly
get evaluated. When printing a commit message that contains parenthesis,
it fails with a shell parsing error.

This gets fixed when we add quotes around the $item variable, and prevent
it from being evaluated by any shell commands.

ktest: Cleanup terminal on dodie() failure

2015-02-02T15:43:39+00:00

If dodie() is called with the console open, restore the terminal's
original settings before dying.

ktest: Print build,install,boot,test times at success and failure

2015-02-02T15:43:30+00:00

Since both success and failure may shortcut and exit ktest, it is better
to print the status times there too. Once times are printed, the values
for the times are reset, so they will not print more than once.

ktest: Enable user input to the console

2015-02-02T15:43:24+00:00

Allow the user to send input to the console by putting the terminal in
cbreak mode (to allow reading stdin one character at a time) and copying
all stdin data to the console's pty.

ktest: Give console process a dedicated tty

2015-02-02T15:43:12+00:00

Create a pseudoterminal (pty pair) to give the console a dedicated tty
so it doesn't mess with ktest's terminal settings.

ktest: Rename start_monitor_and_boot to start_monitor_and_install

2015-01-29T14:02:07+00:00

The function start_monitor_and_boot is a misnomer. It use to, but
now it starts the monitor and installs. It does not boot. Rename it
before I get confused by it again.

ktest: Show times for build, install, boot and test

2015-01-29T14:02:06+00:00

Seeing the times for how long a build, install, reboot and the
test takes is helpful for analyzing the test process. Seeing
how different changes affect the timings.

Show the build, install, boot and test times when at the end of
the test, or between each interval for tests that do those
mulitple times (like bisect and patchcheck).
