Make it possible to manipulate the simple and regexp
tests the LogRequestHandler class uses to check error
messages for potential error states.
This is accomplished by moving the simple and regexp test
strings to class members, where they can be easily
manipulated by users of the pylorax module.
It's also now possible to set the log request handler class
for a LogMonitor.
This functionality can then be used for example like this:
customized_log_request_handler = monitor.LogRequestHandler
customized_log_request_handler.simple_tests.remove("Call Trace:")
log_monitor = monitor.LogMonitor(install_log,
timeout=opts.timeout,
log_request_handler_class = customized_log_request_handler)
This way installation will continue even if there was a call
trace in the logs. In a similar way additional tests and regexps can be
also added.
anaconda-26.1 changed how package scriptlet failures are handled. They
are now fatal, and anaconda hangs after logging an Installation failure.
ERR packaging: Installation failed: PayloadInstallError('DNF error:
Non-fatal POSTIN scriptlet failure in rpm package mlocate',)
Catch this (the 'packaging: Installation failed' part) and terminate the
image creation.
If there isn't enough space for DNF to download packages it will log:
"Not enough disk space to download the packages."
So add this to the messages in monitor that trigger an error.
