Evan and Zope Dev -
I'm using the virtual host monster with apache proxy/rewrite
mechanism. I faced a little bit of trouble dealing with zope's
setServerURL method.
I'm using a configuration such as this on the apache side:
RewriteRule ^/(.*)$ \
http://localhost:1080/Virt

We've had no probs with ZODBCDA connected to SQL Server (7 and 2000). What
leads you to think it's a prob with the DA?

Im getting so
We too are having problems connecting to Access2000 with ZODBCDA. Seemed to
be working fine (and I guess it still does) but it is slowing our whole site
down. all our parts were playing together very well until (we think) about
the 2.3.x introduction.
Our site grinds to a halt and is very slow in
actually, our SQL Server sites are using 2.2.X, so it could be something 2.3
related. were there any aqueduct or other RDB changes done between those
versions? (I don't know of any, but I haven't looked)
pertaining to MySQL, definitely use the native DA since ODBC will simply put

MySQL rocks, but comes short in some of the areas we need. MSSQL is the one
constraint on this project that I cant get around.

Hmmm, interesting I will check the changes. Just curious if you tried the
sites under heavy load, 50 odd request per second+

Under heavy loads (stress testing) I get a lot of sql.errors, ive just
started logging those so I can get exact numbers. Im getting memory leaks,
but Im not sure if that is ZODBCA or not.

Wow came in this morning to find my Zope has :
62642 instances of Shared.DC.ZRDB.RDB.SQLAlias and
32444 instances of Acquisition.ImplicitAcquirerWrapper
According to the debug info I think I have a place to start.

This one?
- SQLAlias objects were leaking when a database column was
accessed via an aliased name. This was tracked down to a
subtle bug in ExtensionClass.

This sounds like a bug that was fixed in 2.3.0 or earlier... I hope it
didn't make its way back in!

Hello guys,
It seems that I've some memory leak problems and I want to understand where
I've to look for.

Hi Andy,
I would venture a guess that your ZODBC problems have to do
with the DA being Level 1.
visit the somewhat dated URL:
http://www.zope.org/Members/petrilli/DARoadmap
for details on what Level 1 through 3 represent.
For an upcoming project we will need to work with MS SQL
server as well
As far as I can tell those changes are still in. Do I understand them? Not
really.

Evan -
I agree with your statement, but the system is behaving differently.
The generated URLs should not have :80 in them and they do not
... rather they have :1080 included in the generated URLs although I
have specifed something as follows:
mod_rewrite result:
proxy:http://localhos
Thanks, well the consensus was that it was level 2. We've talked to Paul
quite a bit about the database adapters for Zope and I'd always said they
work fine for me. Oops :)
Cheers.

I believe it handles the translation of the sql fields from upper to lower
and vice versa. More than that, I'm uncertain.

Any chance you could clarify what SQLAlias does, ive definitely got the case
where some sql queries (and the way they are handled / used) causes an
increase in the SQLAlias count and some dont. Id like to find the quick work

I haven't worked with this code closely in a few months, but as I recall
permissions that are acquired are stored as a list, and those that
aren't are stored as a tuple.

I have the impression its not SQLAlias thats the problem since im also
getting Record.Record, Acquistion.ImplicitAcquirerWrapper and Extension

Will there be an effort to make Zope 2.3.x play with ActivePython 2.0 or is
this a longer range goal ... Zope 3.x ??? I know there are alot of other
irons in the fire but I am just trying to make some design decisions. I am

i was one of the people that ran into big problems with that previous bug.
if that is the one you are coming across, then the problem occurs when you

eg. if you have a column called ID
have you checked the debug page in the control panel and noted any refcounts

any chance that this is the same problem that andy is running into (read his

Im not convinced its just SQLAlias though, I commented out the SQLAlias

Hi Marco,
This looks like a potential bug in either ParsedXML or the code you're using
to manipulate the components within ParsedXML.
We'd like to find out! ;-) Do you think you can file a collector report
with enough information in it to reproduce this behavior?
Many thanks,
