ANNOUNCE: Pound - reverse proxy and load balancer - v0.8
by Robert Segall 01 Aug '02

01 Aug '02

This is to announce the release of Pound v0.8. This release is mostly about bug fixes. Unless some new suggestions come in, the feature set seems to be rather complete at this point. Changes from previous version: - fixed a serious problem: Pound now is able to detect back-end connections that have timed out (closed by the server) and re-open them if necessary. Previous versions would return a "500 Server error" and log "can't read from xxx" in such cases. This issue was mostly apparent with newer versions of Apache that set time limits on connection times. - fixed the request pattern matching as per the RFCs (all allowed character classes). - fixed a problem with the handling of "HEAD" type requests. - fixed an issue with conflicts between SSL and multi-threading. - added a header indicating the origin of the request (X-Forwarded-For) - added the possibility to pass SSL certificate information in headers. 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 (pattern matching) For further information, download, etc. please see http://www.apsis.ch/pound The software is at version 0.8 (beta quality). Further testing (especially under heavy loads), improvements and suggestions are welcome. Pound is distributed under the GPL. 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

Announcement: DirectoryStorage 1.0 alpha 1
by Toby Dickenson 01 Aug '02

01 Aug '02

Announcing the first alpha release of DirectoryStorage, a ZODB Storage which uses one file per revision of an object. * A very simple file format. Your data is not locked away inside an unfamiliar, opaque database. * Easy administration. Nearly as easy as FileStorage, and much less touble than BerkeleyStorage. * Use familiar filesystem tools for maintaining the database. For example: * Take an incremental backup using tar. * Make crucial persistent objects immutable using file permissions * Constant memory usage, even during packing. With the right filesystem I believe this makes DirectoryStorage the most scalable Storage available today. Changes since the previous informal release include: * Many bug fixes. DirectoryStorage is now in production use. * A storage checking tool. Detect any problems early. * Additional fault tolerance to reduce the risk of permanent data loss. * Many performance improvements - now within 50% of FileStorage. If you like the idea of a scalable high performance storage with easy administration, but dont yet want to put your data in alpha-quality software, why not join the dirstorage-users mailing list at http://lists.sourceforge.net/lists/listinfo/dirstorage-users

Organizing new Zope/Python User Group in NC, USA.
by Tom Bryan 25 Jul '02

25 Jul '02

Geoff Davis and I are trying to start a Zope/Python User Group in the Research Triangle area of North Carolina. At the moment, we'd like to keep things very informal. Just a bunch of Pythonistas meeting once a month to share knowledge and listen to someone give a presentation on some aspect of using/hacking/learning Zope, Python, or Jython. The direction the group takes and the topics that are presented will depend heavily on the interest of those who will actually be attending. If you're interested in attending, go to http://dev.zope.org/Members/tbryan/TriZPUG/FrontPage In a couple of weeks, we'll be contacting everyone who adds his or her name to the list to organize a first meeting, which will probably include a presentation from Geoff on using CMF with Zope. Thanks, ---Tom

Version 1.2.1 of ZCGI puts CGI-BIN scripts in the CMF!
by Adrian Hungate 24 Jul '02

24 Jul '02

ZCGI is designed to bridge the gap between traditional web design, and Zope. In a traditional web environment, if you want server-side processing, you write/buy/borrow a CGI-BIN script, put it in a folder that supports the CGI-BIN protocol, and then call it from a link or form on one of your HTML pages. ZCGI was originally designed to do just this, and allow people to slowly move from CGI-BIN to Zope External Methods, Python Scripts, or Python Products, but as the project has progressed, and especially after I released 1.0.0 I realized that there are a LOT of excellant CGI-BIN products out there, and it is simply not feasable to have users or authors transition to fully Zope execution (http://cvs.zope.org uses an excellant CGI-BIN called viewcvs). So, instead of simply making the transition to Zope easier, I have now focused on making as many (Often badly written, or only marginally conformant) CGI-BIN scripts as possible able to run directly under Zope. With this release, ZCGI can now interact with Page Templates by being able to base the output on *standard_template.pt* (Vanilla Zope) or *main_template* (CMF). A number of fixes to the handling of POST content, and the reporting of debugging errors all make ZCGI more usable both in development and production. Many thanks for valuable assistance bug hunting and squashing go to Marc Lindahl - http://www.zope.org/Members/bowerymarc who helped me immensely throughout this development cycle. Thanks also go to Paolo Petta - mailto:paolo@ai.univie.ac.at for finding the bug with multi-value parameters. Thanks to Brett Goodwin - mailto:brett@brettgoodwin.com for finding the bug where scripts that throw before sending output to stdout cause the wrong error to be raised. The new version is available from http://www.zope.org/Members/haqa and now (thanks to ZCGI) you can get the very latest updates from http://cvs.haqa.co.uk/viewcvs/Products/ZCGI !!
