[Zope-dev] Zope and Python compatibility
What would the arguments be for sticking with Zope 2.1.3 for Zope 2.7? I feel most people want to use the latest and greatest versions, usually... Or? Of course, if the requirement could be 2.1.3 *or* 2.2.2, that would be nice, but is that realistic? ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

I feel most people want to use the latest and greatest versions, usually... Actually, most people don't care about the latest and greatest, and would prefer tried and trusted. Especially if the latest and greatest means they have to install more stuff. I disagree. If I wanted to stagnate, I just wouldn't upgrade. Speaking as a joe average user, I'd much rather see forward progress on development. That way, when I do hit a bug with my current (old) version I have somewhere to go. Besides, most systems ship with 2.2.2 right now. Demanding 2.1.3 means installing more stuff for new users, not vice-versa. Right now I'm in a bit of a pickle since our inhouse development is all on 2.2.2. But I'm the sole Zope developer so I have to stick with 2.1.3 (and its weaker error checking). Obviously, they can coexist and that's not a huge problem but it is annoying. I understand that 2.6 runs with 2.2.2... well, that's fine but in the spirit of your comment above: that's a little too far into the realm of the unknown and untested. Without papal blessing, I'm not willing to hack up my 2.6 to run under 2.2.2 and put it into production. There is also the matter of pride. I'd rather have Zope running on the latest and greatest, especially since 2.2 has been out for months now and 2.3 is already alpha. Running under an old version implies that there is something wrong with Python 2.2 or Zope 2.6 that just can't be fixed. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

In practice, Zope 2.6(.x) already fulfills this requirement, it's only that ZC doesn't have the resources to guarantee it. I think 2.7 would be in the same boat. FYI, the current CVS head (to be 2.7) now requires 2.2.2 as per an earlier papal edict. So there will be at least some work involved in making it run under 2.1.3. I kindof feel like we already made a rather firm commitment to *requiring* 2.2.x. I did not fully agree with that decision at the time, but to renig on it now seems fairly counterproductive unless someone can provide a really good reason. I personally feel like Zope should run on 2.2.x whether required or not. Requiring 2.2.x does have the advantage of limiting the possible blessed configurations on which Zope will run, thereby making development, support and bug fixing that much easier. Otherwise I can see having to develop on Python 2.1.x and test on 2.1.x and 2.2.x. It would be nice not to have to do this when developing 2.7 only code. I realize that this would be necessary when backporting things to 2.6. -Casey ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
