ANNOUNCE: Pound - reverse proxy and load balancer - v0.11
by Robert Segall 18 Sep '02

18 Sep '02

This is to announce the release of Pound v0.11. New in this release: - added the ability to track sessions by cookie value or URL parameter value, in addition to IP address. - sockets are opened with REUSE_ADDR to allow for quick restart (the socket is first checked to make sure no other program is really using them). - added code for early pruning of sessions to "dead" back-end servers. - fixed a minor problem with content-less responses. The software is at version 0.11 (pre-production quality). Further testing (especially under heavy loads), improvements and suggestions are welcome. This will probably be the last pre-1.0 release, which will only include bug fixes (not that there are any). The feature set seems to be pretty much frozen - unless someone comes up with a really good, must-have, idea. 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. 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. For further information, download, etc. please see http://www.apsis.ch/pound 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

RE: [Zope] ZCatalog

Can you put a new copy of the ZCatalog in your Yihaw folder, then catalog all objects from there? The only thing that should be cataloged is the Yihaw folder contents and down.

It takes virtually no administration, you can back up a database by just copying one database file, and it has a good optimizer. It is not available for all platforms, though, mostly Windows and a few Unix flavors. Cheers, Tom P

https with 2.5.1
by Ken 18 Sep '02

18 Sep '02

I've recently upgraded from Zope 2.3.2 to 2.5.1 (FreeBSD 4.3). Previously, I was able to fetch and parse https:// pages using KebasData. Now I can't... I have read some posts regarding SSL, patching urllib.py, and M2Crypto, but I never had to do anything special for this to work with Zope 2.3.2. More to the point, these solutions do not seem to apply to Zope 2.5 on a Unix-like os. I would also like to upload https:// documents into Document Library, which also doesn't work. I'm bummed.. Any ideas?

Re. the comments on non-usefulness of multiprocessign with zope: I run zope on a dual pentium VA Linux server and the second process gets seriously used whenever the system is busy. It's quite possible that zope itself is using just one CPU (I didn't bother to check), but as there is lots of other stuff that makes up a running system (including apache in my case), the second processor still is very useful.

Unfortunately I have a ZOPE 2.3.3 site and "Yihaw Folder" is the only metatype to choose. Yihaw objects contained within the "Yihaw Folder" are not listed. This is one more reason for migration to the CMF. Chris Withers <chrisw(a)nipltd.com> on 09/18/2002 05:47:10 AM To: Eric N.

Sure, only select the Yihaw object's meta_type from the multiple select list in the 'Find' tab of the ZCatalog when you're using it to index objects. > Can you point me to some good documentation.

Checking zope userfolder root
by chrisf 18 Sep '02

18 Sep '02

Can this be done from a script? Lets say you have the following directory structure: ROOT/A/B/C/D/E user TEMP is in the acl_user folder in the 'C' directory and hence can log in only at ROOT/A/B/C directory and upwards. lets say he logs in a ROOT/A/B/C/D/E/F I would like to know at which level he was authorized. I am not keen about changing manage user permissions. In otherwords I would like a script that loops back through parents checking to see if folders can be viewed. How can one predict whether a user authorization dialogue will appear. How can one interupt a authorization dialogue from appearing. Thanks Chris

No, that doesn't mean the password has changed. View the sort ;-) The number of stars is due to the placeholders put in so the method can tell whether you have changed the password or not next time you hit that save button. I suspect something else is the problem. cheers, Chris
