Pull ktest updates from Steven Rostedt:
"The following ktest updates were done:
o Added timings to various parts of the test (build, install, boot,
tests) and report them so that the users can keep track of changes.
o Josh Poimboeuf fixed the console output to work better with virtual
machine targets.
o Various clean ups and fixes"

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. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
If dodie() is called with the console open, restore the terminal's original settings before dying. Link: http://lkml.kernel.org/r/20150130025453.GB20952@treble.redhat.com Signed-off-by: Josh Poimboeuf <jpoimboe@redhat.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
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. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
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.

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

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. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
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).

When ktest runs the console program as a child process, the parent and child share the same tty for stdin and stderr. This is problematic when using a libvirt target. The "virsh console" program makes a lot of changes to the tty settings, making ktest's output hard to read (carriage returns don't work). After ktest exits, the terminal is unusable (CRs broken, stdin isn't echoed). I think the best way to fix this issue would be to create a pseudoterminal (pty pair) so the child process would have a dedicated tty, and then use pipes to connect the two ttys. I'm not sure if that's overkill, but it's far beyond my current Perl abilities. This patch is a much easier way to (partially) fix this issue. It saves the tty settings before opening the console and restores them after closing it. There are still a few places where ktest prints mangled output while the console is open, but the output is much more legible overall, and the terminal works just fine after ktest exits.
