Exception in Orange.utils.addons cleanup

An exception occurs when python interpreter is shutting down and is cleaning up the loaded modules (problem reported in  http://orange.biolab.si/forum/viewtopic.php?f=4&t=1739).


python -v -c"import Orange"

on Debian (squeeze) indicates this happens while cleaning up Orange.utils.addons (but does not happen on Mac OSX 10.6)

A quick glance at the module suggest that the problem is the global addons variable. This is a shelve object which has a __del__ method and that is probably where the error happens.

Even if this is not the cause the global variable should be removed and the shelve opened only when required (use with closing(f): construct).

  • Severity changed from major to immediate


python -c"import Orange; Orange.utils.addons.addons.close()"

does not produce the exception, so the diagnosis is probably correct.

  • Status changed from new to closed
  • Resolution set to fixed

I could not reproduce this on a fresh installation of Squeeze, so I'm working blind here. Hopefully this is fixed in commit e0b3d7e.
