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. This is a shallow bug; it's already fixed in Python 2.3 (CVS). > 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. 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 )
[Zope-dev] Problem with Zope 2.6.0 and ZShell
Hi,
Someone has reported to me a problem when running ZShell's latest

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.
