Instead of always showing a backtrace,
- for AppArmorException (used for profile syntax errors etc.), print only
the exceptions value because a backtrace is superfluous and would
confuse users.
- for other (unexpected) exceptions, print backtrace and save detailed
information in a file in /tmp/ (including variable content etc.) to
make debugging easier.
This is done by adding the apparmor.fail module which contains a custom
exception handler (using cgitb, except for AppArmorException).
Also change all python aa-* tools to use the new exception handler.
Note: aa-audit did show backtraces only if the --trace option was given.
This is superfluous with the improved exception handling, therefore this
patch removes the --trace option. (The other aa-* tools never had this
option.)
If you want to test the behaviour of the new exception handler, you can
use this script:
#!/usr/bin/python
from apparmor.common import AppArmorException, AppArmorBug
from apparmor.fail import enable_aa_exception_handler
enable_aa_exception_handler()
# choose one ;-)
raise AppArmorException('Harmless example failure')
#raise AppArmorBug('b\xe4d bug!')
#raise Exception('something is broken!')
