[Zope-dev] Caching ZCatalog results
I'm curious, has anybody played around with the idea of caching ZCatalog results and if I submitted a patch to do this would it be excepted?

Maybe this won't work, after all. I have had little exposure to the actual innards of the Zope 2 catalog, so this might be too wild for good old Zope 2, but here it goes: In Zope3, catalog indices actually only deal with integers (int ids) that only *represent* actual objects (this is for optimization reasons, and so they don't actually have to hang on to persistent objects themselves). This way a Zope 3 catalog search result is actually a list of integers, not a list of objects (or brains, or whatever). Of couse, you can use that list of integers to look up the corresponding objects with an integer ID utility (and there is a convenience API for that, but that's not important). A wild guess is that the Zope 2 index does the same or at least somethign similar. Perhaps not in a nice componentized manner like Zope 3 does (using a separate utility for the int id mapping), but I do recall the ZCatalog storing uids. RAM caching those integers should be absolutely possible. Heck, they don't even need much space and can be kept efficiently in data structures... It may require a bit of hacking the catalog, of course. Perhaps it's time to start thinking about componentizing the Zope 2 catalog to make such things easier in the future? -- http://worldcookery.com -- Professional Zope documentation and training Next Zope 3 training at Camp5: http://trizpug.org/boot-camp/camp5 ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Thanks for that pointer. It's good that way, it should make invalidation easier. It could be as simple as invalidating any cached result that contains the documentId being indexed. Do you see any problem with the following invalidation strategy: If the 'documentId' exists (cataloging existing object), invalidate all cached result sets that contain the documentId. If the 'documentId' doesn't exist (cataloging new object), invalidate all result sets where the ids of indexes applied, are contained in the cache key for that result set. -- Roché Compaan Upfront Systems http://www.upfrontsystems.co.za ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

It would also be interesting to look into making it faster which huge datasets, something that is a problem now. I think it's because you search each index separately and intersect the results, and only then pick out the 20 first results. Compared with Lucene for example, which instead will create iterators who will only resturn the next match. This saves you from a lot of index searching when you have big results. I don't know if it is feasible to do something like that, but it would be interesting to look into it. -- Lennart Regebro: Python, Zope, CPS, Plone consulting. +33 661 58 14 64 ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
Re: [Zope] Error Tracing in Zope 2.6
The event_log isn't recording anything about the Zope error I'm getting on the page I have issues with. Is there a setting that I'm missing maybe? Also, has anyone successfully went from Linux to Windows with their Zope instance? I've noticed things like .read() and .write() don't work in Windows, they throw a Zope error, but they worked fine in Linux. I've also had to deal with the .strftime() function bombing on windows because the field from the database call was null, so it gives me an error about None not having that attribute.

I'm moving my Zope setup from Linux to Windows and apparently there are some syntax that needs to change when migrating over (aside from my SQL command, since I'm going from Oracle to MS SQL Server). Some of these files are big, and there's a done of files to go through, so going through by hand is just not an option. If anyone can give me some pointers to more specifically locate erroneous lines, or if you can give me some tips on what syntax to look out for during the migration, I'd really appreciate it.

Hi all!
Some days ago I begin this threat:
http://www.mail-archive.com/zope@zope.org/msg26355.html
Dieter point me to the solution and I try something like:
def __bobo_traverse__(self, REQUEST, nombre):
obj = getattr(self, nombre, None)
if obj is None:
self.REQUEST.set('TraversalRequestNameStack',
self.REQUEST[TraversalRequestNameStack]
+ [nombre])
resultado = self()
if type(resultado) == type(unicode()): return
WrapperUnicode(resultado)
elif type(resultado) == type(str()): return
WrapperStr(resultado)
else: return resultado
return obj
and the wrappers:
class WrapperStr(str):
__roles__ = None
class WrapperUnicode(unicode):
__roles__ = None
But when I try to launch this zope raises a NotFound exception
If I inspect de content of resultado I could see an unicode string then the
WrapperUnicode is used to wrap the result
Can you point me where the problem is, please?
Thanks a lot!

Re: [Zope] Error Tracing in Zope 2.6
The error_log isn't helping. Apparently if your error is being caught in a try block and uses an standard_error_page to show you the exception and traceback it doesn't get logged in the error_log. Is there anyway to maybe increase the traceback output from the error_tb variable to traceback all the way to the DTML Method file? I'll I get in traceback info is the traceback through the last few *.py files, usually ending in the DTML_Try.py file since the page in practically all enclosed in a try block. Very rarely does that traceback prove useful unless the exception occurred in a PythonScript that was called.

Very rarely does that traceback prove useful unless the exception occurred in a PythonScript that was called. You never mentioned that you were trapping errors! It is not a good idea to have 'practically all enclosed in a try block' (especially if they are unqualified try stmts!) I would remove the try stmts and see what is generating the errors.

[Zope] adding objects to a ZCatalog
Hi, I have a folder called images and a form that to add images to that folder. The form called an external method (../images/addImage) that references a python script, the one I sent earlier, that creates 4 versions of the images in 4 sizes and places them in the images folder. Also in the images folder I have a ZCatalog called ImageData. I'm trying to add a line to the python script to automatically catalog any images that are added to the images folder. I tried ImageData.manage_catalogObject... but I kept getting back: NameError: global name 'ImageData' is not defined. Any advice? Thanks.

[Zope] invalid property value: wrapped object
Hello group: Running Zope 2.6.1/Python 2.1.3, I get the following error when I try to pass form values to a custom ZClass instance-creating method: Error Type: ValueError Error Value: Invalid property value: wrapped object I haven't had to deal with this kind of error before. Does this mean that the wrapped object (aq_parent) has an invalid property value, or does aq_self have the invalid value? What's the most efficient way to debug this? Best, Anthony Do you Yahoo!?

[Zope] Zeo Client Hanging Unresponsive
I have posted this several times, but have not until now been able to
get DeadlockDebugger installed.
zope 2.9.5 + zeo
pythonm2.4.3
Red Hat RHEL 4
Plone 2.5.1
Our zeo clients hang intermittently. We have no way of reproducing the
problem, but it occurs daily. The client hangs and a restart seems to
fix the
problem.
In the event log with tracing on we get
Trace zeo.zrpc.Connection(C) wait(16697) {server:8100} pending, async=0
There are hundreds to thousands of these until the server is restarted.
In the zeo log we get
Error caught in asyncor asyncore.py
error:(110,'Connection timed out')
We have been trying to track this down and have had no luck. Does
anyone have
any suggestions? Below is our deadlock debugger output
