Accepting PEP 405 (Python Virtual Environments)
by Nick Coghlan 26 May '12

26 May '12

As the latest round of updates that Carl and Vinay pushed to the PEPs repo have addressed my few remaining questions, I am accepting PEP 405 for inclusion in Python 3.3. Thanks to all involved in working out the spec for what to model directly on virtualenv, and areas where cleaner solutions could be found given the power to tweak the behaviour of the core interpreter and the standard library. Cheers, Nick. -- Nick Coghlan | ncoghlan(a)gmail.com | Brisbane, Australia

doc change for weakref
by Ethan Furman 26 May '12

26 May '12

I'd like to make a slight doc change for weakref to state (more or less): weakrefs are not invalidated when the strong refs are gone, but rather when garbage collection reclaims the object Should this be accurate for all implementations, or should it be more along the lines of: weakrefs may be invalidated as soon as the strong refs are gone, but may last until garbage collection reclaims the object ~Ethan~
