[Zope] request for advice

[Steve Spicklemire]

Hi Folks,

ZCVSMixin is coming along... there are several things that need to be
done, but I've been on vacation.. I'm thinking of some kind of
fishbowl proposal, but there might be something that could be done
easily to allow it to work 'as is' on Windows. (I run windows only
when I am forced to ;-> ) Here is the only code in ZCVSMixin that
currently makes it fail on Windows:

I started with popen2 and friends.. but that didn't seem to play well
with Zope... probably mixing processes and threads is a bad idea... I
dunno. Anyway I'm not sure of the best way to do this in Windows. Of
course, ulitmately Shane Hathaway's idea of having a separate 'mini
cvs servelet' process running that zope communicates with via tcp/ip
could be the best way to add security and platform independence, but
it sounds like a fair amount of extra complexity to me, esp when I
don't have a lot of 'free time' to implement such a strategy.

Any thoughts about this? 

Also.. I'm trying to find a sane way to handle folder hierarchies with
ZCVSMixin. The main problem I have is separating the attributes of
containers with their contents. Right now the export/import code
treats folderish objects as a 'clump'. I think need a sort of
'export contents' and 'export attributes' protocol so that folders
under CVS control can export their attributes (as if it were some
'content') into some 'special' file, then delegate the exportation of
their contents to the CVS Folder.

Any thoughts about this appreciated! ;-)
