[Zope-dev] MemoryError problem

2009-07-24 Thread Rupesh P Raj 
My application was running fine, but recently it started giving MemoryError:

MemoryError

What does this error mean? Is it saying that the object it is trying to load
has some problems? The object which it was processing before the MemoryError
occured is a normal html page. I am totally lost.

What are the possible reasons for memory error? Any resources in Zope site
or so, from which I can know more of?

Thanks,
Roopesh

[Zope-dev] POSKeyError how to remove

2009-07-23 Thread Rupesh P Raj 
Hi,

Using Zope Debug Console, I used a part of the code fsrefs.py to find the
oid's of POSKeyError:

fs = FileStorage(path, read_only=1)
undone = {}

noload = {}

for oid in fs._index.keys():
try:
data, serial = fs.load(oid, )
except (KeyboardInterrupt, SystemExit):
raise
except POSKeyError:
undone[oid] = 1
except:
if VERBOSE:
traceback.print_exc()
noload[oid] = 1

This gave me one oid.Then I tried something like below :

obj = app._p_jar[oid]

But this gave me another POSKeyError instead :(

Why does this happen? How can I delete this object.

Thanks,
Roopesh

Hi Jim,

But I am using ZODB 3.4.4 :( Are there any other options? How can I find
where this invalid object is being referenced?

Will something like packing resolve this?

Thanks,
Roopesh

 The object is already gone. It's odd that it is in the index.
 You can try deleting the object from the index and then saving the
 index.  You might need to use ZODB 3.9 to do that, as I think __del__
 was only recently added to file-storage indexes.

[Zope-dev] How to use UserTrack product?

2008-09-09 Thread Rupesh P Raj 
Hi,

I am very newbee to Zope. In my Zope application I want to integrate
UserTrack product (we dont use plone). I placed the UserTrack folder inside
the Products directory, and created an instance of UserTrack inside some of
the other zope products, as follows:

u = UserTrack()
logger(str(u.listUserActivities()))

But the list is coming as empty. I think the place where I have initialised
the UserTrack instance is wrong.

In the Readme file which comes along with UserTrack says that, UserTrack
lists the currently active authenticated users that are logged into zope and
accesses an object below the folder where the UserTrack instance resides. So
I guess I need to write initialize in some of the ZMI folder object, but
which one?. Can anyone please help me.

Thanks
Roopesh
