The details are described in "ZSQL/ZSQL.2.5.2.html". You already got this advice. You failed, because you used the wrong kind of quotes (i.e. single rather than double quotes).

Well, as far as I've been able to figure out. But everybody correct me where I get it wrong: When a DTML Document is called from the web, it gets itself as the client argument and a namespace as the second argument. Note that it gets itself twice: first as the standard Python object oriented "self" argument and then as the client argument. I seem to recall there's some magic in there where the the object is wrapped in an acquisition class so that it can do a self.REQUEST, but I'm not sure. Any DTML methods called by the first object get None passed in as the client argument. Importantly, DTML methods do not lookup variables in themselves (i.e. from the Python "self"), but only from the namespace. The original object has been added to the namespace at this point so these called methods are able to access things. An example would be if you had a DTML method called "doit" sitting in a folder next to "standard_html_header". Because doit acquires from its container, you could say "doit.standard_html_header" from Python because standard_html_header is a property of the containing folder. But using "" from inside doit only works if standard_html_header is available in the namespace. External methods add more fun :-). As noted in the documentation, the enclosing folder will be passed in automatically if you call the first argument "self" (and you pass in yourself one fewer argument than the function calls for). Note this is NOT the standard python object oriented "self" argument, which would be the external method sitting in the ZODB if anything, but the enclosing folder. You do have to call it "self" or you don't get anything. The "self" argument is able to acquire REQUEST so you can say "self.REQUEST", but you don't get a namespace automatically. ___ 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] Expression syntax for sort= attribute in tag.
It's very, very... great news that Ross Lazarus's multikey sort patch for dtml-in tag is included in current Zope CVS and will be included in Zope 2.2. But for me one important thing is very missed. Possibillity of use expression syntax for sort= attribute. Maybe syntax: would be possible ? eg. where fun() will returns appropriate Python string eq.

It doesn't seem to have a major impact on my problems at least...neither does Zen's latest set of fixes. I enabled Neil Schemenauer's fixes, rebuilt python, and then tried tracking through chunks of the CPickleCache code. There did not seem to be any hanging python references. I believe the problem to be circular zope references on a higher level. I could be wrong though. The gc code for cPickleCache.c is not trivial, and I believe there is something wrong there, but have not proved it yet. This is the code that determines when things are removed from the zope cache. The wierd thing is that in my case, I am not really writing anything to the Zope db. Everything is stored externally in a postgres database. I am using GUF, and SQLSession though. Could it be that connection objects are not being cleaned up properly? As far as I understand it, connection objects are containers for zope objects for the duration of that request. At least in the case of postgres 6.5.3 there was some connection memory leaks, so I did try postgres 7.0, it solved some of postgres's problem but not zope's. sorry for rambling, just trying to get all of the tidbits that I know out there, maybe someone will see something. eric. > > http://www.enme.ucalgary.ca/~nascheme/python/gc.html > > I'd like to know how successful this project is.

[Zope-dev] New GUF (1.2.3)
I think I've fixed the memory leak identified over the weekend in GUF.
This leak may also have caused {SQL,FS}Session to leak through no fault of
their own. Could people who are experiencing the problem try out the
new version and let me/zope-dev know the results. I'll announce the release
on zope.org soonish, giving the guinee^h^h^h^h^h^hzope-dev members a
chance to give it a poke.

I'm just downloading LoginManager now to see if I can steal their fix :-) (Oh... thats easy. Just search for 'Waaa!') There is also a good chance that this is also causing the SQLSession leak - GUF is maintaining a reference to REQUEST (in a nice circular way causing the memory leak), and REQUEST maintains a reference to the SESSION, so the SESSION won't be freed. I should have a patch available shortly.
