October 2002 - Zope-Announce

New zope.org development
by Guido van Rossum 31 Oct '02

31 Oct '02

There have been complaints about zope.org. The complaints include things like "the design is ugly", "the navigation is difficult", "it's too slow", and "search results are not useful." For a long time there have been plans to convert the site to the current version of Zope using CMF, and various false starts have been made, but so far the site is still running software that's best described "FrakenZope 2.3"... I opened my big mouth, and now I'm responsible for fixing this. :-) Actually, a new plan was already in place, and all I have to do is coach its execution. Zope Corporation has retained a highly skilled Zope developer, Sidnei da Silva, to do the work. The advantage over Zope Corporation developers doing this (as has been tried in the past) is that Sidnei isn't likely to be pre-empted by higher-priority customer work: for him, this *is* customer work, the customer being Zope Corporation. At the same time, because Sidnei is being paid, the expectation is that the plan will be carried out at a steady pace, as opposed to simply "letting the community sort it out." Sidnei's plan includes the following pieces: - use Zope 2.6 with CMF 1.3 for the new site - use a new skin design, the winner of the zope.org contest - use the new ZCTextIndex search engine - migrate all existing users and as much content as practical to the new site (There's more, but we'd be getting into detail territory.) The project goals include minimizing the amount of new code and content to be created, in order to minimize the risks of failure. We also strive to make future maintenance of the site simpler, both at the sysadmin level (process and resource control) and at the webmaster level (content control). All these goals are designed to make sure that the site can be kept current once the upgrade is in place. Time-wise, Sidnei expects a preview version of the new site to go up as new.zope.org within a month, and the final version to go live (replacing the old www.zope.org) within 2-3 months after that. Sidnei expects to be asking community help with some tasks; he'll post about this himself. In addition, we're also hoping to hire Sidnei as part-time webmaster for zope.org, starting next week. Having a steady webmaster will help the site stay accurate and up-to-date. --Guido van Rossum (home page: http://www.python.org/~guido/)

Re: [Zope] ANNOUNCE: Pound - reverse proxy and load balancer - v1.0
by Casey Duncan 31 Oct '02

Caching has nothing to do with bandwidth and everything to do with handling large numbers of requests per second. Something Squid excels at. Caching removes load from the Zope server as well, potentially increasing the responsiveness of non-cached pages too. That said, Pound looks like a pretty cool piece of software. -Casey On Thu, 31 Oct 2002 11:43:27 -0500 Eron Lloyd <elloyd(a)lancaster.lib.pa.us> wrote: > Awesome!

ANNOUNCE: Pound - reverse proxy and load balancer - v1.0
by Robert Segall 31 Oct '02

31 Oct '02

This is to announce the release of Pound v1.0. New in this release: - Pound is now declared to be production-quality code - fixed a few minor problems, such as the ordering of certificate file - removed thread auto clean-up due to a bug in the Linux implementation of libpthread - added support for additional WebDAV commands (Microsoft-style) - restructured request match patterns - added support for HA ports for back-end hosts - added support for optional HTTPS extra header The software is at version 1.0 (production quality). Further testing (especially under heavy loads), improvements and suggestions are welcome. What is Pound (from the Web page) - a reverse-proxy: it passes requests from client browsers to one or more back-end servers. - a load balancer: it will distribute the requests from the client browsers among several back-end servers, while keeping session information. - an SSL wrapper: Pound will decrypt HTTPS requests from client browsers and pass them as plain HTTP to the back-end browsers. - an HTTP/HTTPS sanitizer: Pound will verify requests for correctness and accept only well-formed ones. - an HTTP/1.1 to 1.0 proxy. - a fail-over-server: should a back-end server fail, Pound will take note of the fact and stop passing requests to it until it recovers. - a request redirector - it will pass client requests to separate groups of servers, based on required URL and the presence or absence of headers (pattern matching) Pound was specifically developed to serve as a front-end for multiple instances of Zope running on top of a common ZEO storage, but can be used with any other web server. A patch for the Python source of z2.py is available as part of the distribution to allow using Pound's SSL capabilities. Pound is currently in use in several medium to large volume sites and seems to be holding up quite well: largest reported site does about 3.5 million requests per day, peaking at over 300 requests per second. The speed is well superior to other, equivalent solutions, the configuration is much simpler and the necessary resources (CPU, RAM, disk) are much, much lower. Pound is distributed under the GPL. For further information, download, etc. please see http://www.apsis.ch/pound Enjoy and let me know how it works for you. -- Robert Segall Apsis GmbH Postfach, Uetikon am See, CH-8707 Tel: +41-1-920 4904

ZODB 3.1 / ZEO 2.0 released
by Jeremy Hylton 28 Oct '02

28 Oct '02

I am pleased to announce the final releases of ZODB3 3.1 and ZEO 2.0! ZODB is an object database for Python that provides transactional persistence while requiring few, if any, changes to application logic. ZEO is a client-server storage system for ZODB. The ZEO package is released on its own and as part of ZODB3. The separate release is for Zope users, who already have ZODB. Source releases are available from: http://www.zope.org/Products/StandaloneZODB http://www.zope.org/Products/ZEO http://sourceforge.net/projects/zodb The ZODB3 release requires a C compiler, while the ZEO2 release is pure Python. Windows users can download a binary installer for Python 2.2.2 from: http://www.zope.org/Products/StandaloneZODB The components you get with the ZODB3 release are: - Core ZODB, including the persistence machinery - Standard storages such as FileStorage - Supporting modules such as ExtensionClass - The persistent BTrees modules - ZEO (versions 1 and 2) - Experimental Berkeley storages - Updated documentation The final release contains roughly the same version of ZODB that is available with Zope 2.6. The two releases are not directly coordinated, so there may be some minor differences. Many people have contributed to ZODB3. Special thanks to Toby Dickenson for the new ZODB Connection cache. Many people at Zope Corp. have contributed code and tested unreleased versions. There was only one change since the last beta release. A problem with unexpected exceptions in conflict resolution was fixed to allow transactions to fail more gracefully. (This change actually restored the pre-ZODB3 behavior.) Jeremy

Bug in Zope 2.6.0: Fix availiable
by Lennart Regebro 27 Oct '02

27 Oct '02

Zope 2.6.0 has a bug in DateTime.rfc822(). The bug appears when you are NOT in a DST timezone, causing a "Name Error: Global name localzone is not defined" error. This will affect many parts of your Zope operations, luckily, the fix is simple: - Download the fixed DateTime.py, from http://www.zope.org/Members/regebro/datetime_260_fix - Put the downloaded DateTime.py into the lib/python/DateTime directory, replacing the one that is there. - Restart the server. This fix is ONLY valid for Zope 2.6.0. Earlier versions of Zope does not have this bug, and this fix will be included in any future releases of Zope. Best Regards Lennart Regebro http://www.easypublisher.com/

the CMFCollective wants you!
by alan runyan 25 Oct '02

25 Oct '02

We are trying to aggregate all quality CMF products under 1 CVS project at sourceforge. Currently there is only 1 project, CMFBlogger imported but there will be quite a few more. CMFPhoto, CMFForums and most likely CMFCommerce. If you are a CMF developer and would like to check in your code. Please email me runyaga(a)myrealbox.com with what your code is and your sourceforge username. I will add you so you can import the modules ASAP. http://sourceforge.net/projects/collective/ ~runyaga p.s. if someone can port Backtalk to CMF, that would be a really nice addition to the collective. p.p.s. CMFCommerce can be found in the Plone CVS. I am not answering questions about it until I publicly release it.
