PEP 3003 states that Python 3.2 will be released 18-24 months after Python 3.1. Python 3.1 was released on June 2009-06-27 [1], so theoretically Python 3.2 should be released not before 2010-12-19 [2].
The PEP 3003 text isn't allowing for the fact that 3.1 is "3.0 as it should have been", so the starting point for the 18-24 month rule of thumb is actually back when 3.0 was released in Dec 2008. This was discussed a fair bit back when the decision was made to do the short release cycle between 3.0 and 3.1 in order to address some of the more glaring shortcomings of the 3.0 release.
I agree with everybody else who said that a) there was *no* consensus that the release cycle for 3.2 should be shortened because of 3.1 being released early. I also remember the opposite. b) whatever past discussion may have been, it would be a mistake to release 3.2 earlier than 18 months after 3.1. Of course, 2.7 *could* be released by the proposed schedule; it just would have to be decoupled from 3.2 (just as 2.6 eventually got decoupled from 3.0). I personally think that decoupling the releases would be best, i.e. not start thinking about 3.2 for another 6 months.

Fair enough - I didn't remember that discussion all that well, but assumed it had reached that consensus due to the lack of comment when Benjamin originally posted his proposed schedule. Your response and Guido's clearly indicate otherwise :) If that wasn't the consensus, then all the dates should slide back 6 months (i.e. no alphas until June 2010). (I actually prefer that since it gives me a chance to find a cleaner approach to the runpy.run_path problem, but didn't want to rehash a discussion I thought we had already had)
Of course, 2.7 *could* be released by the proposed schedule; it just would have to be decoupled from 3.2 (just as 2.6 eventually got decoupled from 3.0).
That leads to a 2.x version with features that aren't yet available in a 3.x version though. I thought we weren't planning on doing that anymore.
I personally think that decoupling the releases would be best, i.e. not start thinking about 3.2 for another 6 months.
Or just have the timing be 18 months for 3.2 and 24 months for 2.7 (i.e. push the first alpha of both back to June next year).

Afterwards, the new Windows 7 buildbot has hung in test_multiprocessing, but I don't know whether it's related. Regards Antoine. Guido van Rossum <guido <at> python.org> writes:
I would remove them -- if and when we find there's a need for something like them I suspect it won't look like what you currently have, so it's better not to complexificate your current patch with them. (I would remove all traces, including the conditions passed into the end macros.)
My only suggestion so far: the description could use more explicit documentation on the various variables and macros and how they combine.
Is it before or after http://mail.python.org/pipermail/python-checkins/2009-
November/087482.html ?
After. While that is already really helpful, not all the code is easily linked back to paragraphs in that comment block, and some variables are not mentioned by name in the block.

The buildbot waterfall is much greener now. Thanks to all who have contributed to making it so (and it hasn't just been Mark and Antoine and I, though we've been the most directly active (and yes, Mark, you did contribute several fixes!)).
The buildbots still show occasional oddities. For example, right now in the page "http://www.python.org/dev/buildbot/3.x/", some results have disappeared (the columns for "AMD64 Ubuntu" builders have become empty). Moreover, some buildslaves have gone back in time (they are building r76188 after having built and tested r76195)... I swear the new GIL doesn't include a time machine.

Yes, I noticed it too. It will go away after some page reloads.
Moreover, some buildslaves have gone back in time (they are building r76188 after having built and tested r76195)... I swear the new GIL doesn't include a time machine.
That's because I resubmitted these changes after restarting the master.

I personally think that decoupling the releases would be best, i.e. not start thinking about 3.2 for another 6 months.
The problem with that is that there is a period of time where 2.x has features which 3.x doesn't. My preference is to move back the whole schedule 6 months. -- Regards, Benjamin ------------------------------ Message: 7 Date: Tue, 10 Nov 2009 23:09:42 +0100 From: "Martin v.

Ok, fine with me as well. FWIW, I don't see that (2.7 released before 3.2) as a problem (but I understand that others might, for what I would consider formal reasons).
