I see new releases of 2.8x, 2.9x and 2.10x, and I dont understand the differences.

What's the difference between 2.8.x and 2.9.x?

Dear all after the annoucement of Zope 2.8.7 and 2.10.0.B1, I'm a bit confused about the difference between the 2.8 and 2.9 lines? Is it mainly Python 2.4 support? Thank you, and best regards, Martin Gfeller

Isolating changes that can only be done globally
by Michael Vartanyan 30 May '06

30 May '06

Hello All, This is probably more a Python question but maybe you will have a quick solution for me - I guess the greatest *multi-threaded* Python application provides the greatest basis for this problem domain :-) The situation: external method that is doing a http request using urllib2. I don't care about the response, and whether there was any response at all, I just need to send the request through - thus I want this request to time out very fast (let it be 2 seconds). I found no documented way to set the timeout for urllib2, after some googling I found an advice to manipulate the timeout on the lower-level socket module, something like this: import socket import urllib2 def do_request(): timeout = 2 socket.setdefaulttimeout(timeout) req = urllib2.Request(url='http://my.site.com/do_something_quick') response = urllib2.urlopen(req) The problem is this way this default timeout is set for _all_ new socket created by this Python process using the socket module. Even if I return the default to its previous state after the request it won't help me much - there are three more threads in my Zope that should be able to work with default timeout. So there are two possible solutions - to find a (preferably documented) way of accessing and parameterizing the socket object created by urllib2 to make a request or to find a way to isolate(??) global module settings between Zope threads. Zope 2.8.3, Python 2.4.2, FreeBSD 4.10 if this is relevant. Any hints/TFMs? Many thanks Michael

Preventing Zope Spinning?
by Brian Brinegar 30 May '06

30 May '06

The majority of the Purdue University Engineering web presence is provided via a cluster running ZEO. We offer hosting for every school, department, faculty, staff, and student in the College. Because of this we have a large number of content maintainers/developers on our system. We are running into problems with users writing bad code which spins or uploading huge files which seems to tie up the database for long periods of time. We end up in a situation where something will spin a client and a user will repeatedly resubmit the request until all of our zeo clients are spinning. Our clients are eventually killed, usually manually, and quickly come back up. We drop the zeo cache on a restart to improve startup speed, so when the clients do come back up we have 100% cache misses and the zeo server gets pounded resulting in slow performance until the client caches repopulate. Occasionally we can track down the offending URL and correct the problem, sometimes we cannot. Perhaps these issues will be addressed in future versions of Zope, we are currently running Zope 2.6.4 What I would like is some sort of timeout for requests, however I do not want to punish users with slow connections. Perhaps a way to kill off a specific request that is consuming excessive resources, without killing the entire client. Below is some information on our setup: 1 zeo server (Solaris) - 82 gig datafs - transaction time out of 120 seconds 2 load balanced zeoclients (Linux) - 2 gig zeo cache - Database Cache 30000 objects - 4 threads 2 failover apaches (Linux) - using pydirector for load balancing We are receiving appoximately 1 million hits per day, which from what I've read is not all that much. We probably have a higher number of DB writes than usual because of the number of developers/maintainers. Can anyone make suggestions for providing a more stable environment? Thank you, Brian Brinegar Web Systems Developer Engineering Computer Network

hello list! I want to profile some http methods (GET, POST) for Zwiki; (I am not an expert in Zope ); I tried a requestprofiler.py and I need to get execution times at a lower resolution (millisecs); could be possible? or any other method to get the execution time the most accurate possible ; thanks for any hints DanielG __________________________________________________ Do You Yahoo!?

[Ann] Zope 2.8.7 released
by Andreas Jung 29 May '06

29 May '06

Hi all, on behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.6. You can download Zope 2.8.7 from http://www.zope.org/Products/Zope/2.8.7/ Some new features of Zope 2.8: - ZODB 3.4 with MVCC (multi version concurrency control) support. MVCC solves nearly every problem with ZODB read-conflict errors which is very important for high-traffic Zope sites. - Extension Classes were rewritten as Python new-style classes making all features of Python new-style classes available in Zope objects. This includes support for cyclic garbage collection. - Integration of Zope 3 technologies through Five (see http://codespeak.net/z3/five/) For more information on what is new in this release, see the CHANGES.txt files for the release: http://www.zope.org/Products/Zope/2.8.7/CHANGES.txt See also: http://www.zope.org/Wikis/DevSite/Projects/Zope2.8/OverView Please bring all the bugs you have found to the Zope bugtracker: http://collector.zope.org/Zope":http://collector.zope.org/Zope For more information on the available Zope releases, guidance for selecting the right distribution and installation instructions, please see: http://www.plope.com/Books/2_7Edition/InstallingZope.stx Please also keep in mind that Zope 2.8.7 requires Python 2.3.5. Zope 2.8.7 is not certified for any Python 2.4.x versions. So using Python 2.4 is neither recommended nor supported and any related questions or problems are likely to be ignored until 2.4 is an officially supported Python version for Zope. -- Andreas Jung (andreas at zopyx dot com)
