Zope 2.6.2 Now Available Zope 2.6.2 represents a development step in the next Zope release formed with a large number of community contributions. You may download Zope 2.6.2 from Zope.org: http://www.zope.org/Products/Zope/2.6.2/ Users of the Zope source release should note that Python 2.1.3 is now the required platform. Python 2.1.3 includes a fix to an issue that could cause crashes in Zope. Users who upgrade from source MUST RUN a make clean and make command to build the proper binaries correctly; distutils will skip compilation of the library modules needed for Zope and will cause errors if they are not up to date. Particular features of interest in Zope 2.6.2: * Fixed an error where ZClasses that subclassed ObjectManager would not load. * Fixed a case where objects trying to check access rights on behalf of another user were unable to do so. * Fixed memory leak with Page Templates * Python 2.2 compatibility fixes * Back ports of BTrees fixes * Back ports of ZODB fixes relating to the packing of storage, where a packed database could contain an UNDO transaction which referred to data which had been discarded by the pack * A fix for fsrecover.py which prevented it from recovering any data * Fixes for collector issues 256, 514, 683, 814, 816, 823, 875, 882, 892, 902, 928, 937, 939, 954, 956, 959, 964 For more information on what is new in this release, see the CHANGES.txt and HISTORY.txt files for the release: * http://www.zope.org/Products/Zope/2.6.2/CHANGES.txt * http://www.zope.org/Products/Zope/2.6.2/HISTORY.txt For more information on the available Zope releases, guidance for selecting the right distribution and installation instructions, please see: http://www.zope.org/Documentation/Misc/InstallingZope.html -- Matt Kromer Zope Corporation http://www.zope.com/

DirectoryStorage 1.1.4
by Toby Dickenson 08 Sep '03

08 Sep '03

Announcing DirectoryStorage 1.1.4. This is the first release where the majority of changes have been driven by the user community... Is this a sign of DirectoryStorage maturity? This release fixes several bugs: 1. DirectoryStorage could deadlock ZEO under high load. Thanks to James E. Blair for reporting this and testing the fix. The deadlock occurs in code which provides guarantees relating to the timestamps of files in snapshot mode. This release fixes the deadlock by dropping support for file timestamp guarantees. Please read the changelog if you are relying on file timestamps during snapshots (for example, if you are using your own custom incremental backup solution) and raise any questions on dirstorage-users(a)lists.sourceforge.net 2. Fixed Overflow error in checkds when calculating statistics of very large storages. Thanks to Paul Winkler for reporting the problem and providing the fix. 3. Fixed incorrect import when generating an error message. Also thanks to Paul Winkler. This release has not been through my personal QA process due to a hardware failure on the workstation where I usually run those tests, therefore I am labelling this as a beta release for now. I would be grateful for any feedback. Download: http://sourceforge.net/project/showfiles.php?group_id=53818&release_id=1832…

mail is working again
by Barry Warsaw 04 Sep '03

04 Sep '03

I believe that the mail system for python.org and zope.org is now working again. We had several problems related to our Exim installation, running out of disk space, and our spam/virus defenses. Please note that it is possible that some legitimate messages got lost. It may take a while for all the Exim and Mailman queues to get cleared out, so please do not resend your message right away. But if your post does not reach the intended mailing list or python.org recipient within a few days, you may need to resend it. Huge thanks to Jeremy Hylton, Andrew Kuchling, and Skip Montanaro for helping me get the system up and running again. -Barry

[Ann] DocFinder 1.0: ask Zope about its documentation
by Dieter Maurer 25 Aug '03

25 Aug '03

It is often difficult to find accurate documentation about the Zope infrastructure. Often, I have written: look into the Zope source, its source documentation is quite good. However, as Zope's implementation language Python provides good introspection facilities, there is a better way: extract the documentation directly from Zope. That's what 'DocFinder' does. It analyses any Zope object inside a running Zope, determines which classes have been used in the object's makeup and provides information about their class level attributes: name, allowed roles, arguments, documentation strings. It provides (read only) access to to source code of Python implemented classes and methods, as well. What's new in version 1.0: * Direct access to source code of Python implemented classes and methods * Implemented as a single persistent <code>DocFinder</code> instance (rather than a DTML object and External Method pair) * Alternative URL-calling to document objects which intercept traversal * Now uses PageTemplates rather than DTML for presentation More information and download: <http://www.dieter.handshake.de/pyprojects/zope/DocFinder.html> Dieter

@python.org and @zope.org email troubles
by Martijn Pieters 22 Aug '03

22 Aug '03

Thanks to the enormously proliferant W32.Sobig.F, the mail.python.org email server has been having real trouble dealing with the flood of email pounding on it's ports. We are currently hard at work trying to bring the mailserver back to sanity again, and you should be seeing email emerge again, although it may take some time still before things will be back to normal operation. In the meantime, we apologize for the inconvenience. -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

VarImage 2.3 Released
by Terry Hancock 20 Aug '03

20 Aug '03

VarImage means "Variable Image" -- it is a Zope product which allows you to load a single image and serve modified versions of it, but with efficient caching. Thus you can have most of the flexibility of "on-the-fly" image generation, with very little penalty compared to pre-prepared images. Available from: http://www.anansispaceworks.com/papers_html#VarImage-2.3.tgz Provided plugins allow for: scaling, resizing, cropping, foveal thumbnailing, photonegative, black-and-white conversion, color tinting, superimposition of "image components" to construct composite images, and simple drop-shadow effects. Although VarImage itself does not explicitly rely on Python Imaging Library, all of the currently distributed plugin operators do. VarImage supports a simple plugin API for writing your own image operators. New in 2.3: Interactive graphical ZMI tool for setting the image fovea. (Requires manager to use a javascript/CSS capable browser -- tested working on Mozilla 1.0.0, Konqueror 2.2.2, probably works on IE 5+ (untested), doesn't work on Netscape 4.77). "Key" syntax for calling from Python expressions or code, e.g.: <dtml-var expr="my_image_png['tn_100_100.jpg']"> Streamlined regeneration code, and fixed several bugs affecting large or unusual images. Foveal thumbnailing algorithm fixed for some edge cases that failed to preserve correct aspect ratios. There is also a "drop shadow" plugin, contributed by Andrew Meier, and a "no-op" plugin for testing images for PIL compatibility. Improved the failover behavior for errors occuring in the plug-ins (usually in PIL): in most cases, a "VarImage Error" will be served if the conversion fails. Enjoy!
