In the restricted code, right at the start. Restricted code loads its own copy of each module it uses. The glob module uses re, which uses sre. --Guido van Rossum (home page: http://www.python.org/~guido/) ___ 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 )

Thanks for your answer. Unfortunately I never import sre. I import re, then rexec in the main program, then in the restricted code I add the os and os.path modules, and the resticted code then import the glob modules and calls its glob method. So should I set sys.hexversion *before* my re and rexec imports in the main program, or add the sys module and a fake hexversion value in the restricted code ? thanks in advance Jerome Alet ___ 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 )

Not that deep actually. sre.py line 168 is this: if sys.hexversion >= 0x0202: > Since I don't actually use Zope 2.6, does anyone have an idea on > where the problem may come from ? You're using restricted mode (the rexec module) and this apparently doesn't provide sys.hexversion.

Probably those versions of Python didn't have the test for sys.hexversion; it's testing whether this is Python 2.2 or higher. A workaround would be to set sys.hexversion to 0x0202 (or to 0 if you're not sure which Python version you're using) before importing sre for the first time. --Guido van Rossum (home page: http://www.python.org/~guido/) ___ 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] CMF, CMFCore/utils.py, Tuple/List incompatibility
I had the same problem once. It turned out that I had called manage_setLocalRoles with a tuple instead of a list, but as you found out some code expects all local roles to be stored as the same sequence type, and Role.manage_addLocalRoles enforces the invariant that a changed role is stored as a list. I think manage_setLocalRoles should be changed to enforce that invariant.

This seems to be deep in Python standard library.
Since I don't actually use Zope 2.6, does anyone have an idea on
where the problem may come from ?
Does any of you use ZShell with Zope 2.6 ?
It works fine in 2.5.1 with Python 2.1.3, so something has
changed somewhere which breaks it.
ZShell's latest version is available from :

Thanks in advance for any pointer.

This worked fine. Thanks. Hi, I'm having the same problem migrating a zclass from 2.5.1 to 2.6. I've tryed the collector fix of ZClasses/ObjectManager.py and the subobjects tab thing, but that didnt solved my problem. My zclass has ZFolder as base class instead of ObjectManager: Base Classes: ZObject, ZFolder, CatalogAwareBase I'm looking at the ObjectManager.py to see if I can put it to work for my zclass, but I think in my case that doesnt make sense because my class dont have a subobject tab... I'm looking into the zen of iclass... Any ideias? thanks. Regards, Julio Silva I'm forwarding this mail to zope-dev because since this is related with 2.6.0 development changes against 2.5.1 maybe someone has other solutions, because the that is out there for ObjectManager doesnt solve my problem.
