All in all, only a few days separate the two releases, and obviously CVS people have been able to get at changes all along.

Dieter Maurer wrote: Zope 2.4.3 will not work with Python 2.1.2. This is not literally true. Zope 2.4.3 will work fine with Python 2.1.2. However, Python 2.1.2 doesn't ignore stacksize computation problems like Python 2.1.1. Instead of silently corrutping memory and continuing like 2.1.1, Python 2.1.2 will stop with an assertion error. This means that Zope 2.4.3 won't really run under 2.1.2 for very long if you've got a codepath that tickles a compiler package bug, but at least it won't fail mysteriously with odd symptoms. Zope 2.4.3 will run for *longer* under Python 2.1.1, but it will fail with other more mysterious symptoms. Hopefully, this will clear some of the confusion up. For maximum stability if you're running some 2.4.X-series Zope under Python 2.1.X: - Upgrade your Zope to 2.4.4 (wait for final if you don't like the current beta status of 2.4.4) - Upgrade your Python to 2.1.2 Do these two steps *at the same time*. You should have increased stability and availability after that. - C ___ 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 )
Re: [Zope-dev] [BUG] Python 2.1.2 Zope 2.4.1
Olivier Deckmyn wrote assertion STACK_LEVEL() = f-f_stacksize failed: file Python/ceval.c, line 687 This is a new assertion, put in to catch the case where the RestrictedCompiler code used by PythonScripts incorrectly calculates stack size. After some hours of researches, I have a (dirty, really) fix : I had to modify Python sources and hack line 687 in ceval.c : I removed it... This is _not_ a fix, any more than putting in a signal handler for SIGSEGV that ignored it and kept going would be a fix for a segfault bug. The bug is _real_ and causes memory corruption. The most likely result is that Zope will crash mysteriously, some time later down the track, but it's also possible you'll end up with random data corruption. This is _far_ worse than just a crash. If upgrading to 2.5 or 2.4.4-to-be is not an issue, just replace the lib/python/RestrictedPython package in your Zope installation and reboot. Please, please, please, don't propagate dodgy and incorrect fixes like the above (removing the assertion). The assertion is in the code for a very, very good reason.

But couldn't find another way to have my servers restart this sunday. I just regret that this problem was not warned anywhere clearly. I must not be the only one that have had seen this happen ! But I know it now :-) Anyway, many thanx to every one who gave help.

[Zope-dev] [BUG] Python 2.1.2 Zope 2.4.1
Hi, I decided to upgrade my Python 2.1.1 to Python 2.1.2 (in order to gently move to 2.5 later). My Zope instances were working quite finebut...randomly I got a core dump (!) and the following message in logs : assertion STACK_LEVEL() = f-f_stacksize failed: file Python/ceval.c, line 687 Bug seems to appear when playing with ZCatalog (CMF sites could'nt even render a page) and Python scripts ? After some hours of researches, I have a (dirty, really) fix : I had to modify Python sources and hack line 687 in ceval.c : I removed it... Then recompile and it seems to work. I know this is dirty, and my Zope my crash later. PLEASE CHECK and HELP ! This looks like a major serious bug to me.

Re: [Zope-dev] [BUG] Python 2.1.2 Zope 2.4.1
This has been explained recently (-- mailing list archives, probably through Google search for f_stacksize). I did, without a great success. Summary, you need to upgrade Zope, too! If only I could... You can't make your customer migrate their Zope version in 2hours. Our servers are hosting dozens of website for dozens of customer. Moving to a newer Zope is not just a matter of installing a new version... For example, we have a CMF site that will only work with Zope 2.4.1. We tried to migrate to CMF 1.2 or Zope 2.4.3, without success (crashes, security machinery misteries, etc.). CMF is still too dark to manipulate it as we would wish.
