Releasing RevisionManager 1.2rc1
by Philipp von Weitershausen 30 Apr '03

30 Apr '03

Hello everybody, Once again, I am proud to announce another RevisionManager release. A big thanks goes to ZopeMag which has been sponsoring development since the 1.0 release. The first release candidate for RevisionManager 1.2 brings the following changes: * Many performance improvements have been made. Performance has more than doubled for some actions. Thanks to Dieter Maurer for ZopeProfiler which made profiling very easy. * RevisionManager now has simple support for branches and sticky tags (creating a new branch, moving to a branch, reverting a sticky tag). * RevisionManager can use the name of the user that is currently logged onto Zope to connect to a pserver or RSH/SSH server. * RevisionManager can now append ZODB history information (changes to the object since the last RevisionManager action) to the log message upon committing objects. Be aware that this slows down committing because each objects has to be comitted independendly. * Added 'force checkout' action. This allows one to force a checkout and thus revert local changes. * Several bugfixes. Thanks to Christian Theune for helping debugging a very tricky bug. If you already have an instance of RevisionManager, please follow the instructions in the INSTALL.txt file, section 4 Upgrading. You may download RevisionManager at: http://www.zope.org/Members/philikon/RevisionManager Best regards, Phil

Releasing ZopeTree 1.2
by Philipp von Weitershausen 30 Apr '03

30 Apr '03

Hello everybody, I am releasing ZopeTree 1.2. ZopeTree is a light-weight and easy-to-use tree implementation, mainly designed for use in ZPTs. I wrote ZopeTree because I found ZTUtils.Tree too complicated and not flexible enough. Changes since 1.1: * Added optional 'expanded_nodes' argument to ZopeTree constructor. Thanks to Jean Jordaan for suggesting this. * Changed signature of TreeObjectWrapper constructor. 'path' is an optional argument now. Warning: If you are using TreeObjectWrapper, you will have to update your PageTemplates! * Added collapse() method to ZopeTree.Node. There is no explicit README file, but you should be able to read everything from the interfaces. The product also comes with two example PageTemplates. You may download ZopeTree at: http://www.zope.org/Members/philikon/ZopeTree Regards, Phil

ANNOUNCE: Pound - reverse proxy and load balancer - v1.4
by Robert Segall 24 Apr '03

24 Apr '03

This is to announce the release of Pound v1.4. Changes in this version: - support for certificate chains - user-definable error pages - new Server configuration directive - compatability with OpenSSL 0.9.7 - compile-time flags for running in foreground and/or logging to stderr - some bug fixes and speed improvements The software is at version 1.4 (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 5.5 million requests per day, peaking at over 450 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
