Re: [Zope-dev] Re: Zope 2.4 crashes -- possible fix identified, other solutions also suggested
The new compiler fixes that we have to date are actually in 2.4 branch and 2.5 branch as well as the trunk; they're in the lib/python/RestrictedPython/compiler directory; so you could go to http://cvs.zope.org and just pull down that directory (optionally pulling down your specific branch too). Pythonlabs is working on a few more cases which I expect will be done and checked in RSN; then we'll backport those to the branches so you don't have to install a new python to get the fixes with Zope. Anthony Baxter is anticipating a Python 2.1.2 beta real soon now (probably this weekend) so I am going to try to get that into Zope 2.5's binary releases, although we may put out a Zope 2.5 beta 3 first. This will include the necessary Python patches to ceval.c to fix the frame bug; after it hits the streets Python 2.1.2 will become our recommended Python for Zope. The ExtensionClass.h patch has NOT been merged into the branches and trunk yet pending further review. - Original Message - From: "Joseph Wayne Norton" <[EMAIL PROTECTED]> To: "Matthew T.

I just found out that the RestrictedPython package isn't actually yet fixed! Shane is working on it.

Note that at the time that it's fixed, all that needs to be done is to download the tarball as per Martijn's instructions, move the current "RestrictedPython" package aside, and put the new RestrictedPython package in its place, restart Zope. - Original Message - From: "Leonardo Rochael Almeida" <[EMAIL PROTECTED]> To: "Zope Developers list" <[EMAIL PROTECTED]> Sent: Wednesday, December 19, 2001 2:24 PM Subject: Re: [Zope-dev] disabling gc does not necessarily hide memorycorruption > > On Wed, 2001-12-19 at 13:34, Chris McDonough wrote: > > It would be good if someone who is experiencing random crashes could confirm > > that the the new compiler package fixes their problem. > > I might risk losing a few more points with my sysadmin to test it (Hi > daniduc :-) if there was an easily downloadable package with clear > instructions on how to apply it to Zope 2.4.3 (I don't feel like messing > with CVS for this), and if you tell me that it won't corrupt my Data.fs > or anything :-) > > Cheers, Leo > > -- > Ideas don't stay in some minds very long because they don't like > solitary confinement. > > > ___ > 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 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] disabling gc does not necessarily hide memorycorruption
I'm not sure the ExtensionClass fix is baked yet, and there's not yet an overwhelming consensus that it helps stability, not to mention that I'm not sure how to install it, so no. ;-) I think you can use the trunk, no branch required.

One sample scenario: - Create a template for a diagram in OpenOffice - Uploade it into Zope and add some dtml-vars (or ZPT expressions) to the XML file to make it dynamic (e.g. to create web usage statistics) - Users can not only see and download the diagram as gif (which is possible right now using GDChart or so), but can also download it as a valid OpenOffice (or, if reconverted, also PowerPoint/Excel) doc. That diagram contains the dynamically created numbers, but can be edited locally. Does OpenOffice support WebDAV already? That would be very useful. Similar things could be done with KOffice.
