[Message part 1 (text/plain, inline)]

In case I forget I wanted to report a bug with parted where Control-C is treated as an OK response.  I was testing how parted handled a corrupt primary GPT and was rewarded with parted asking if I wanted to use the backup GPT instead with the prompt: "OK/Cancel? " I typed Control-C and it took it as an OK response.


$ parted fu print unit s print unit chs print

WARNING: You are not superuser.  Watch out for permissions.

Error: The primary GPT table is corrupt, but the backup appears OK, so that will be used.

Also was going to open an enhancement request for parted to force it to use the backup GPT no matter what the state of the MBR and primary GPT.  This would be useful if case the MBR and/or primary GPT were corrupt (think: "dd if=/dev/zero of=/dev/sdX bs=512 count 130" or something similar).

Thanks for the report, it looks like we've got some places where
ped_exception_throw return values aren't being checked properly -- ^C
should generate a PED_EXCEPTION_UNHANDLED and I see a number of places
that don't take that into account.

I'm not sure this isn't actually intentional.  What should parted do
when run in scripting mode?  There all exceptions are unhandled, so a
sane default action must be taken.  I think this particular error
really should be a warning, and the default is to proceed, using the
backup copy.
