TCP CLOSE_WAIT leaks
by Alan Milligan 04 Apr '06

04 Apr '06

Hi, I've been noticing a situation for some time that my 2.8.5 Z2 is running out of threads. When doing an lsof on it, I see a large number of TCP handles in CLOSE_WAIT state. It seems something's not properly clearing down the connection to release the thread. Unfortunately, these connections were almost guaranteed to have been set up via Apache redirect processing, and it's quite successfully cleaned up its end ... Does anyone have any idea how this situation might occur, and why Zope's not properly housekeeping these (maybe Medusa needs a timeout set on close waits??) Alan

Bug in Zope 2.9?
by Chris Withers 04 Apr '06

04 Apr '06

I see the following the first time a Zope instance is started under 2.9: 2006-04-03T10:59:30 ERROR Zope A problem was found when checking the global product registry. This is probably due to a Product being uninstalled or renamed. The traceback follows. Traceback (most recent call last): File "C:\Zope\2.9.2\lib\python\OFS\Application.py", line 260, in checkGlobalRegistry keys=list(self._p_jar.root()['ZGlobals'].keys()) File "C:\Zope\2.9.2\lib\python\OFS\Uninstalled.py", line 46, in __getattr__ raise AttributeError, escape(name) AttributeError: keys Seems odd. What does it mean? Should I expect it? How come it no longer happens on subsequent startups? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

This worked fine in 2.7, why am I seeing it now? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Is TF IDF implemented in zope search engine. On NED in Zope.
by Manuel Vázquez Acosta 02 Apr '06

02 Apr '06

Hi all, I was reading a paper on News Event Detection (NED) and I started wondering how hard would it be to implement such a mechanism in Zope. My first step was to find out if Zope already implemented a vector space model (tf idf, maybe) for indexing and searching the documents. I know nothing of Zope internals yet. So, I'm counting with your help for me to start digging into Zope's. Best regards and thanks in advance, Manuel.
