[Zope-dev] help identifying a structure inside Zope.
I'm hunting for a very very obscure python-crashing bug on Solaris with Zope2.4 on Python2.1.1. The structure that's getting corrupted looks something like: 299, (300, (301, (302, (303, ( 304, ( 3, "c_o_s" ) ) ) ) ) ) (nested tuples) I'm wondering if anyone can think of somewhere inside Zope that generates this sort of structure? "c_o_s" is a string we use in our code as a property, a database column, and a REQUEST variable. As far as we can tell, it's not something being generated by our code...

Re: [Zope-dev] BUG or FEATURE?
Its the , that mucks up the namespace lookup for "value"
Doesnt work:, works:
But with REQUEST is a rather wierd thing to do. Are you sure you want to do
that?
Cheers.

Just FYI, this works "right" (IMO) under FreeBSD: files untarred as root are owned by root unless you use the p flag. Of course, this note only applies if you are just handling this item via doc changes; if you have install do the chown, it's moot. --RDM ___ 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 )

It isn't immutable. The second and subsequent sets should work.
> <== only works first time it
Well, I don't know quite what you are observing, but this code is broken.
Inside the quotes you are in python mode, and 'sequence-item' in python mode
is the variable sequence minus the variable item. Since it didn't throw an
error, you must have variables by those names that understand substraction.
Try _.getitem('sequence-item') instead.
I suspect this thread belongs on zope, not zope-dev.

To my understanding, versions are implemented as long running transactions against the ZODB.

[Zope-dev] BUG or FEATURE?
Today i've got a problem with the dtml-with tag, as follows: I was trying to set a variable, using REQUEST.set inside a dtml-in, inside a dtml-with, but it only works the first time i call REQUEST.set. Subsequent calls do not modify the variable, and do not raise an exception. Not even a simple error. I dont know how it was supposed to work, but i think that if the REQUEST was immutable inside a dtml-with, it should be not allowed to call REQUEST.set inside it.

So there I was in this discussion about Zope versioning (again) and there were two features requested that seemed perfectly reasonable at the time, - to have a list of all the objects changed by a version - to be able to individually commit or discard changes in a version on a per object basis This is would be extremely useful for those times when you forget to check out of a version and accidentally lock the root folder (This happens quite a bit). Simple I thought, but ugh versions go all the way down to FileStorage and got into ZODB stuff I didnt understand.

There's a section in lib/python/OFS/DTMLMethod.py which was changed in 2.4.2 to accelerate DTML security processing, but it doesn't look like a subsequent patch to make it handle reentry was routed to 2.4 yet. (Actually, I think it's waiting in a dev branch, because it's not on the trunk yet either.) For the time being, what you can do is comment out both lines in DTMLMethod.py which read self.__dict__['validate'] = security.DTMLValidate and del self.__dict__['validate'] It looks like the renderable product you're using is causing the DTMLMethod to be reentered, which is tripping out this bug (ie you can only delete validate once -- the second time it fails). ___ 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] [Bug+Patch] Microseconds in DateTime
[Sent to main list, ignored. Retrying here...]
The __str__ function in DateTime.DateTime cuts off two precision digits
from the time returned by time.time(), falling off to tenths of
milliseconds instead of keeping the microseconds.
If it feels unrighteous to put the hard work of gettimeofday() to waste,
apply the patch below to lib/python/DateTime/DateTime.py, and get back
that microsecond precision.
Yes, on some hardware/software platforms those microseconds are
significant, and yes, they can be useful in many situations.
Here is the patch.
