It over there:
The customer is currently testing out an application using it so it's
supposed to work.
What remains to be done is porting the tests (which sounds like a big
deal looking at the non standard tests there...)
I don't know. I was definitely experimenting. :-/ And the "tests"
of the client don't deserve the name. I plan to do much better with
the new version.
Note, this branch is using an "in house" persistent queue replacing
BTrees within the zasync manager.
Of course, I'd like to put this branch back to the zope.org repository
but please not in CVS... I don't feel courageous enough to branch and
merge with CVS anymore...
Would it be possible to migrate the zasync
component from the cvs.zope.org to svn.zope.org ? I don't know who can
do that ? (Hopefully, we'll have a ZF soon...)
I don't care about migrating the history, so if noone else does
either I could try doing a migration.
Gary, it would be an occasion to check you persistent queue and see
we could add this to ZODB and make zasync use it.
Cool. Yes, I'll try to get the persistent queue in ASAP. I have a
few small changes, and then I need to make the test changes that
Other question : how people would feel about an integration of zasync,
or another implementation, into the Zope core ?
The functionality is certainly very, very useful for large sites (and
for any site that needs big work done on demand, I guess). I wonder
if the configuration approach I took makes it too heavy for the core,
though. Certainly, this was a first generation, and there are a
number of things I wish I had done differently, beyond better tests:
I started writing them down here, in the beginning of what I plan to
be a Zope3-based rewrite (largely ZODB-based, hopefully, rather than
too many dependencies on Zope 3; we'll see):
Zope 2 isn't WSGI/Twisted yet, is it? The zasync rewrite (which I'm
working on occasionally personally now, and will need at work in a
couple of months) might work pretty well in Five if the Twisted
reactor is used in Zope 2. If not, maybe someone knowledgeable in
Medusa could write an equivalent. Finally, maybe others have a
zasync approach that would be a better choice.
Within a month or so I hope to put up a proposal for the zasync
rewrite so folks can comment on it and see if it's going a direction
they like (or see if they can push me in a direction they like :-).
I am hopeful that it will feel "lighter" than the current
Alternatively, if there's an effort by other folks to write another
approach entirely, cool!
