Re: [Zope] Question: How to generate a core file in Solaris 2.6
I had a similar problem quite some time ago.

Re: [Zope] Zope eating CPU/RAM - how do I find the culprit?
If you are using ZSQLMethods and your database returns column names in one case (UPPER) but you reference them with another (lower) it appears that instances of SQLAlias get leaked.

Re: [Zope-dev] SQLAlias Memory Leak?
I've seen this as well under DCOracle. -jon Dyon Balding [EMAIL PROTECTED] writes: OK, I've had more of a hack at this, and I've narrowed the problem down a little. It appears that any access to an SQLAlias object causes it to not be correctly released. The SQLAlias objects means that you can access column names using a different case to how they are stored in the database. For example, we store users in a users table in the database, with column names like USERNAME, but they are accessed with: dtml-var username, this causes the SQLAlias objects to stick around. One solution to our problem is to just do a dtml-var USERNAME instead. However that doesn't solve the problem with this "feature" of being able to call it with a different case. This is a fairly easy bug to reproduce, on my setup at least :). I have tested it with ZSQLRelay and ZODBDA both talking to SQLServer, and with ZPyGreSQLDA talking to PostgreSQL.

Sorry Jon, i've lead you down a slippery slope...
unlike ttw dtml-methods and the rest of zope which relies on the
security context soley, for a filesys python method to be exposed
through the web via xml-rpc it must have a doc string as well as have
proper credentials.
looking through propertysheets there is no 'proper' way to do this...
but i lead you down the path, so here is a way back out...
there are a couple of options.
the easiest is to have dtml_method for this zclass that functions as a
helper method,
like
dtml method -- external_helper
dtml-var "propertysheets.propertyMap()"
and in the client
x = root.subfolder.zclass.external_helper()
meta_info=eval(x)
print meta_info
({'id': 'vvv', 'type': 'int', 'meta': {}, 'mode': 'w'}, {'id': 'aaa',
'type': 'lines', 'meta': {}, 'mode': 'w'}, {'id': '', 'type':
'tokens', 'meta': {}, 'mode': 'w'}, {'id': '122', 'type': 'date',
'meta': {}, 'mode': 'w'}, {'id': 'ff', 'type': 'float', 'meta': {},
'mode': 'w'}, {'id': '', 'type': 'text', 'meta': {}, 'mode': 'w'})
or if external_helper returned propertyItems()
[('vvv', 1), ('aaa', ['']), ('', ['ss', 'aa1113', '3', '4']),
('122', DateTime('1900/01/01')), ('ff', 455.0), ('', '')]
if you're working with DateTime values in your propertysheets this will
be trickier as you'll need to either retrieve the property you want
independently or import Zope's DateTime module. also remember to set the
security on the helper method so its not helping somebody hack your
site.
