Zope 2.1.4 released...
by Brian Lloyd 09 Feb '00

09 Feb '00

Hi all, Zope 2.1.4 has been released. It can be downloaded from Zope.org at: http://www.zope.org/Products/Zope/2.1.4/ This update prevents the REQUEST object from being traversable by web clients. While this feature was useful for debugging, Evan Simpson noted a potential security issue that could allow web authors to play client scripting tricks and make them appear (to the user) to be coming from a Zope site. While we know of no instances of this happening and the actual security of the Zope site's data is not affected by this, we do recommend that you upgrade to 2.1.4 to avoid any problems. Also (I know many of you are already thinking it :), we are working on a way to distribute "patch" releases for things like this to make updates easier. Until then, for those who _really_ just want to patch your installation you can replace the file lib/python/ZPublisher/BaseRequest.py in your installation with the one from the 2.1.4 distribution and restart your Zope instance.

Xmlt 1.10 - generating html documents with a common layout
by Anders Andersen 07 Feb '00

07 Feb '00

Xmlt 1.10 - generating html documents with a common layout Xmlt (pronounced ex-melt) merges a layout description with the document contents and generates a html document. Xmlt (Xmlt Merges Layout and Text) uses the DocumentTemplate module from Zope [1] to merge a layout (described in a dtml-file) and the text (found in xmlt-files) into a html document. Its main purpose is to separate the layout description from the contents description of html documents and to reuse the layout description in a large number of documents. Xmlt is originally written to maintain my personal web pages, but it might be useful for other web page maintainers and html document authors too. Xmlt is available for free with code, documents and examples. Send any comments to me (my email address is found in the signature below). I guess it is a little bit strange to use Zope technology to generate static web pages, but I found dtml very useful in the context of a lot of documents with similar layout. I use good old make to generate and install my web pages after I have done any layout or contents changes (I will consider to trash make when the Software Carpentry Open Source Design Competition [2] has come up with a new tool-set that can replace good old make :-). Xmlt, a user guide and some examples are available from the Python starship: ftp://starship.python.net/pub/crew/anders/xmlt/ ftp://starship.python.net/pub/crew/anders/xmlt/doc/xmlt.html Anders, [1] http://www.zope.org/ [2] http://www.software-carpentry.com/ -- Anders Andersen - <mailto:aa@computer.org> - <http://w3.to/andersen/>

SQL Sessions allows you to store arbitrary per-visitor state in an SQL database. http://www.zope.org/Members/nemeth/usingSQLSession * John Udell <udell(a)monad.net> wrote "How-To: A <dtml-calendar> example", which demonstrates managing per-date data with the <dtml-calendar> tag presenting the interface. http://www.zope.org/Members/judell/CalendarTagExample * "anthony" submitted "How-To: Choosing to store data in SQL vs ZODB". In it, he supplies a number of questions you can ask yourself to determine whether to keep application data in the Zope database or an external one. http://www.zope.org/Members/anthony/sql_vs_ZODB * Miklos Nemeth <nemeth(a)iqsoft.hu> has written another HowTo targeted at RedHat 6.1 users: "Zope and Apache on RedHat 6.1". http://www.zope.org/Members/nemeth/howtos/zopeandapacherh61 * Another Chris McDonough <chrism(a)digicool.com> HowTo: "Using the Zope Debug Log to Track Down Hangs".

by Ava 19 Jan '00

19 Jan '00

This release fixes a significant bug in local nt domain determination to upgrade, delete the old nt user folder, install the new product, restart zope and create the new user folder Still no doc, you have to read the source to understand the product. Remember: this is alpha quality code! It works for me, but I expect to change a few fundamental things in the short term. Regards, Jephte CLAIN minf7(a)educ.univ-reunion.fr

mod_pcgi2 version 1.0.0
by Oleg Broytmann 18 Jan '00

18 Jan '00

Hello! After some period of testing, after getting few success stories I changed the module version to 1.0.0! Welcome here: http://www.zope.org/Members/phd/mod_pcgi2 Almost nothing have changed since version 0.4.0. I made some cosmetic changes, but there are few of them. If you are running 0.4.0, you don't need to upgrade. I've tested the module on pentium linux and sparc solaris, in DSO (shared apache) and non-DSO (static, all apache modules compiled in). The only test I didnt tried is uploading huge binary file via PCGI. I am freezing my work on the module for some period (or until I got a bug report). It seems I don't need new features, entire PCGI protocol is implemented, and the module is well tested, debugged and now is used on a few sites (I have no URLs of other sites, only my URLs). The next thing to implement will be autoconf/configure to make installation simpler; after some period I hope to return to work on it.
