[Perl-workflow-devel] Cached condition bugfix

[Alexander K. <ak-...@cy...>]

Hi Jonas,
Hi all,

I've just checked in a bugfix for the cached condition handling.
In OpenXPKI, under mysterious circumstances, we ran into a race
condition where a workflow checked the state of its forked child
and the result of the checking condition and its inverse (using the
'!'-syntax) where either both true or both false sometimes.
This is the same race that was to be prevented by implementing the
'!'-syntax in the first place. Apparently, my fix that cleared
the condition cache so that circular workflows would not run forever
reintroduced the race again :-(
The fix now resets the condition cache on state changes and when
get_available_action_names() is called and introduces corresponding
tests.
Jonas: a quick maintenance release incorporating the patch would be
highly appreciated ...

Best regards,
    Alex

P.S.: Sorry to hear about EBADCONTRACT :-(
