ah...are you using any custom types ? unfornately I had to shake up the interface for the TypeEngine object again. otherwise, yes id need more detail since all the unit tests pass.

Mike, thx

True, for the simple example it worked, but now I get an exception for my
application code.

  File "build/bdist.linux-i686/egg/sqlalchemy/engine.py", line 868, in
__getattr__
File "build/bdist.linux-i686/egg/sqlalchemy/engine.py", line 812, in _get_col File "build/bdist.linux-i686/egg/sqlalchemy/types.py", line 57, in engine_impl
    ClassType = type(_C)
File "build/bdist.linux-i686/egg/sqlalchemy/types.py", line 70, in copy
    try:
NotImplementedError

Do you need more detail, should I try to isolate what usage leads up to this?

Cheers, Florian

download the trunk and you will see your memory usage is steady as a

Hi,

Since more then one processes modifies my database I invoke
objectstore.clear()
prior to fetching data I need to display.

I noticed that I have a huge objectleak all around (about 10k
objects never get
collected at every request)

I wrote a testprogramm (atached) wich in a nutshell does
while 1:
  select
  objectstore.clear()
  gc.collect()
  print len(gc.get_objects())

The numbers rolling down my screen never stabilize or decrease
until the
processes gets an out of memory exception.

However when I take the objectstore.clear() out, the number is
constant (this is
not a solution for me, see first paragraph).

I also noticed that this doesn't happen on windows, only on linux.

I'm using:
cxOracle
Python 2.4
RedHat EL4
sqlalchemy 0.1.6

Cheers, Florian
