Pythons prior to 2.1.3 lacked checks to assert that the data structures were properly generated, and would go off the deep end once they hit them. Python 2.1.3 will recognize bad structures and stop (albeit with messages that are cryptic to someone who isn't aware of the potential pitfalls). I dont remember off the top of my head what the magic "recompile all" url is, but it's there, and it should show up in the debug log when you restart and it notices that the magic number on python scripts has changed. -- Matt Kromer Zope Corporation http://www.zope.com/ ___ 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 )

Ahh, thanks! I think I found the right patch and all. Won't get to find out if it all works until tomorrow. (After the keynote of course ;) Hopefully this nails the issue.

have you read about the python crash-bug stemming from tiny thread stack sizes on freebsd and applied the patch? the mailing list archives should tell you what to do. jens On Tuesday, July 16, 2002, at 09:43 , Jeffrey P Shell wrote: > For a while now, Tracker has been core dumping on my with Zope 2.5.1 > with > both Python 2.1.2 and 2.1.3 on FreeBSD 4.5 (Intel).

[Zope-dev] Restricted Compiler issues on FreeBSD? (Core Dumps...waaa!)
For a while now, Tracker has been core dumping on my with Zope 2.5.1 with both Python 2.1.2 and 2.1.3 on FreeBSD 4.5 (Intel). The culprit seems to be expressions that are heavy on parenthesis. For example, the following works: But it core dumps when changed to: Don't ask me what this expression does - I just kept whittling at it until the crashes stopped. Then I went and found quite a few others. I made a lot of fixes by turning complex expressions into many smaller ones inside a single 'let' tag. Does anyone know other possible fixes for this issue? Is there some Python stack size setting I can set at compile time? I have some other code that has not survived the move to Zope 2.5.x/Python 2.1.x/FreeBSD. FWIW, the Python 2.1.2 used was from the BSD Ports, while the 2.1.3 was compiled by hand. -- Jeffrey P Shell www.cuemedia.com ___ 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 )
