ZConfig change breaks Zope 2 and Zope 3
by yuppie 08 May '05

08 May '05

Hi! On Windows, this 15 months old change in ZConfig sets the default hostname for inet_address to 'localhost': http://svn.zope.org/ZConfig/?rev=376&view=rev I have no idea why this was changed, the checkin message is not very helpful: "fix the default hostname for address datatypes for Windows" This ZConfig change is responsible for the Zope 2.8 release blocker http://www.zope.org/Collectors/Zope/1728 (the relevant info is in http://www.zope.org/Collectors/Zope/1507) and caused similar problems with Zope 3 http://www.zope.org/Collectors/Zope3-dev/383 http://mail.zope.org/pipermail/zope3-dev/2005-March/013770.html So if nobody can tell me why ZConfig was changed, I propose to 1.) revert the change and tag a new version of ZConfig 2.) update ZEO: the ZEO tests expect the old behavior, see http://mail.zope.org/pipermail/zope3-dev/2005-March/013794.html 3.) update Zope 2 trunk and Zope 3 trunk to the new versions of ZConfig and ZEO 4.) fix http://www.zope.org/Collectors/Zope/1507 and http://www.zope.org/Collectors/Zope3-dev/383 I'd volunteer to do the necessary changes in Zope 2. Any comments? Any volunteers for the other tasks? Cheers, Yuppie BTW: Why is ZConfig not a svn:external in Zope 2 and 3?

Zope 2.8, Five and Interfaces
by yuppie 06 May '05

06 May '05

Hi! I had a closer look at Zope 2.8's Five and I'm concerned about the fact that Five ships with redundant interface definitions: - redundant code is always a problem because it's hard to keep things in sync - the fact that Five is maintained in a different repository and should work with different Zope versions makes it almost impossible to change Zope interfaces in a consistent way So my questions are: 1.) Why are interfaces that are available as Zope 2 interfaces duplicated in Five/interfaces.py instead of bridged? 2.) Could we move the interfaces that are currently not available as Zope 2 interfaces to the corresponding packages in Zope 2.8, using Five/interfaces.py just as an fallback for Zope 2.7 and old Five products? If people agree that this is problem, I'd volunteer to help resolving it. Cheers, Yuppie

Using Pyrex (with BTrees)?
by Andreas Jung 02 May '05

02 May '05

Has anyone tried to use Pyrex with BTree datastructures? I tried to use Pyrex to optimize a bottleneck in TextIndexNG3 where an iteration over a list of word ids (and insertion into an IOBTree) takes very long. Unfortunately the C extension produced by Pyrex behaves differently from the original code because several unittests do fail...anyone with similar experiences? Andreas

how to capture testrunner output
by Simon Michael 30 Apr '05

30 Apr '05

Hi all. How would I capture the output of test.py ? 2>&1 seems not to help. Also, shouldn't it exit with a failure code when tests fail ? If anyone has made this work, I'd appreciate hearing about it. Cheers -Simon

Hi, the upload didn't work again. If someone could put the file located at http://amy.gocept.com/~ctheune/Zope-2.8.0-b1-win32.exe to the right place? The proxy on Zope.org caught me again.

Thanks Zac... it doesn't appear as if there is an easy way around the ZEO problem, without involving another large amount of complexity. I'll bump heads with a few of the local Zope gurus and also see if the Pound (our http load balancer of choice) developers have any suggestions.

Windows Binaries for 2.8b1
by Christian Theune 27 Apr '05

27 Apr '05

Hi, and again, I got to complain about building Zope on Windows. This time it's the 2.8 branch again with the 2.8b1 release. It looks like the WinBuilders aren't taken care for at all. The ZClass tests didn't got into the procedure of getting packaged so I had to copy those files manually for running the tests. Then the doctest module doesn't comply with platform independent handling of path names using 'variable.split("/")' and relatives. The now running tests fail pretty much in various places (Catalog, ZODB, ...) I'm not able to do any work on this as I'm lacking time. I took the job of building the releases as long as it's pressing the "do it now button" and running the tests seeing them pass. I did not take the job of cleaning up Zope for Windows. The WinBuilders are a really annoying thing, I'm glad they went away for Zope3. To notice: Zope 2.8a1 has not been available as Windows release and neither will be 2.8b1. You really want to blindly go forward for an RC not having a single external user running any 2.8 release at all? I'm pretty annoyed right now.

ZEO, FastCGI and Shibboleth
by John Snowdon 26 Apr '05

26 Apr '05

Hey Zope-Dev, We're currently in the middle of a UK JISC funded project to evaluate the use of Shibboleth in authenticating access to electronic learning resources in a Medical Education environment... we use Zope and ZEO extensively already, in providing an online learning environment, personal diaries and progress portfolios and many other aspects of the MB BS degree scheme here at Newcastle. I've been looking at the ways in which others have 'shibbolized' their Zope systems... and most (well, the only ones I can find any technical documentation on) have used the Apache + FastCGI approach, along with the RemoteUserFolder product. I've already had test infrastructure in place and have tested with client side certificates in place of a working Shibboleth server (passing the Client cert CN as the remote user variable) and everything works rather well. The problem I'm facing is that the vast majority of the services we offer are hosted on multiple ZEO nodes, behind a load balancing front end server. This was a completely new infrastructure put in place less than a year ago - replacing a monolithic (and ageing!) Sun Enterprise system... Each node is lightweight, hosting only a ZEO instance... a physically separate Apache server is used very rarely, and mainly only for serving static content (static content URLs are caught by the load balancer and sent off to Apache)... this setup has given us excellent performance, and reducing Apache to a static content serving role has simplified things greatly... so we are reticent to change this. The only way I can see the Apache/FastCGI/ModShibboleth and Zope/RemoteUserFolder setup working, is if each ZEO instance has its own Apache server sitting in front of it.... which is something we have moved away from for obvious reasons. Has anyone any thoughts about how to go about shibboleth enabling a whole host of ZEO instances... without each one having an Apache server sitting in front of it? Or is there an alternative method out there that perhaps is not widely known? I know Zope4EDU is enabled, out of the box, but the licensing costs are simply not affordable for the number of hosts (6 discrete hosts), sites (at least half a dozen) and cpu's (12/14+) that we would be using...
