[Ann] Post-Authentication-Hook patch
by Dieter Maurer 23 Sep '03

23 Sep '03

In some case, you want to take special actions once the user has been determined at the end of traversal. You may, e.g., want to deny Manager role to any non HTTPS request. This patch adds support for a *post authentication hook*. It adds code to the 'validated_hook', called when the user is successfully authenticated. The code tries to acquire an object 'post_authentication_hook' from 'request.PARENTS[0]'. If this is successful, it calls this object with the arguments 'request' and 'user'. Usually, this call will raise Unauthorized when it has objections against the request. Download: <http://www.dieter.handshake.de/pyprojects/zope/postauth.pat> Dieter

Zogger 0.9 Released
by Terry Hancock 22 Sep '03

22 Sep '03

[Edited to include download site -- Terry] Zogger is a "Zope Ogg Player" Actually it seems to play mp3s too. This is really the work of jlguiapplet, an applet from "JavaZOOM", which is basically a WinAMP/XMMS clone that runs as an applet. Zogger deploys the player and acts as a song folder in Zope, holding "Audio Track" objects which are expected to be ogg or mp3 files. A subfolder, "skins" contains .wsz (winamp-compatible) files which control the appearance of the applet. The default skin in Zogger is AcquaXMMS, by DOlson, which happens to look fairly good with the default Zope/ZMI color scheme, but the skin can be changed simply by uploading a desired skin and setting the "skin" property of Zogger. Embedding the applet is as trivial as using a Zope image, and uses the same basic mechanism, so you can use a line like: <dtml-var songs> where "songs" is a Zogger instance. Zogger is licensed under the GPL and includes the jlguiapplet (LGPL) and default skin (GPL). It is a pure-python Zope Product, and has no special dependencies. The jlguiapplet is for "Java 2", so the user will need to install the Java plugin for their browser (this appears to happen automatically with Internet Explorer, BTW). Get Zogger 0.9 at: http://www.anansispaceworks.com/papers_html This is "version 0" code, because there are a number of basic features missing: -- Audio Track files are *assumed* to be audio data. No checking of the file format is done. The results of loading something else are not defined. -- No meta data is extracted from the Audio Track files, so the automatically generated song titles are simply the Zope title, and the track length is not correct. These limitations are largely because I don't currently have pyogg/pyvorbis installed on my Zope server, but it shouldn't really be hard to add these features -- I think Audio Track *should* try to load the meta data from the Ogg file as Zope properties (or at least attributes), but it doesn't do this yet. However, it does seem to work reasonably well, and I have deployed Zogger on my personal site at: http://www.anansispaceworks.net/Narya_Net/Home/Terry Which is why I wrote it, in fact. ;-) Cheers, Terry -- Terry Hancock ( hancock at anansispaceworks.com ) Anansi Spaceworks http://www.anansispaceworks.com

[Ann] ManagableIndex: combine value, control acquisition, check types
by Dieter Maurer 21 Sep '03

21 Sep '03

ManagableIndex can mean different things for different people. For a content manager, it brings flexible field and keyword indexes managable via the ZMI to * combine values from different sources, ignoring irrelevant values and transforming values in an inadequate form, Example: index an object via title if it is non-empty but use id otherwise Example: add portal_type to the Subject index transforming it into a sequence (as required by a keyword index). * control acquisition and prevent acquired values to be indexed * ignore stop-terms, normalize terms and check types Example: when you do not want that an object is indexed under a meaningless default value, you can define this value as a stop-term Example: the BTrees underlying Zope indexes require its keys to have a persistently consistent ordering. When this is not the case, they become corrupt. While modern Python versions (at least Python 2.3) compare values from different elementary types persistently consistent, the result can be quite unintuitive. Therefore, it is best when all terms in an index belong to the same types. Normalizing and type checking helps to ensure this. For a developer, ManagableIndex provides a framework for index definition, improving on PluginIndexes. It provides for managability, automatically and intelligently handles unindexing when an object is reindexed and implements and, or and range queries (for not too complex indexes). ManagableIndex requires OFolder. You can download OFolder from <http://www.dieter.handshake.de/pyprojects/zope> More information: <http://www.dieter.handshake.de/pyprojects/zope/ManagableIndex.html> Download: <http://www.dieter.handshake.de/pyprojects/zope/ManagableIndex.tgz> Dieter

MailBoxer 2.3.0 released
by Maik Jablonski 16 Sep '03

16 Sep '03

Hi to all, I'm happy to announce a new major release of MailBoxer - the mailinglist / newsletter / mailarchive - framework for Zope. Where can I download MailBoxer? http://www.zope.org/Members/mjablonski/MailBoxer Please note: Zope.org is a little bit buggy and the prior release (2.2.6) stands above 2.3.0. Don't know why... What's new? * added very nice MailBoxer-Logo provided by Karsten W. Rohrbach. Thank you so much, Karsten!!! The logo is just as I imagined MailBoxer in my dreams. GREAT WORK! Please note: The MailBoxer-Logo is distributed under the Create Commons License (see http://creativecommons.org/licenses/by-nc-sa/1.0/) * added batchsize: Now you can determine how many recipients are bulked in one mail to the smtp-server. This is useful if your mail-server can't send huge lists at once or remote servers don't accept really big recipient-lists. Default is bulking in one batch as in previous releases (batchsize = 0). Many thanks to Patrick G?nther for testing a pre-release with a really huge list!!! * made all properties deleteable, so they can be acquired from a parent-container if you delete them. * refactored code from index_html into mail_index. This allows you using PageTemplates for displaying the archive much more easily (see README.txt). Enjoy MailBoxing... Maik.
