TriZPUG May Meeting: ReportLab - PDF made easy The Triangle Zope/Python User Group (TriZPUG) will hold its next meeting on Wednesday, May 28, at 6:30 p.m. in Raleigh, NC. We will be meeting in the DELTA conference room(s) at Venture III, who has kindly permitted us to use their meeting room, on NCSU's Centennial Campus. Directions to Venture III are below. Ian Sparks will be giving a talk on the ReportLab library. Hope to see you there! Title: ReportLab - PDF made easy ================================ Reportlab is a python library for the creation of Adobe Portable Document Format (PDF) documents. This talk introduces the foundation of the library: the canvas object. We'll start with canvas primitives : drawing, writing text, importing graphics etc and go on to examine how the canvas exposes some of PDFs special capabilities. Finally we'll take a look at PLATYPUS (Page Layout and Typography Using Scripts), a high-level library built on the canvas which makes creating complex documents a breeze. Directions to the TriZPUG Meeting: ================================== If you need directions to NCSU's Centennial Campus, try the following link http://centennial.ncsu.edu/howtogethere/htgh.htm If you need directions to the Venture III building, follow this link http://lts.ncsu.edu/about/venture3.html, but skip step #3 since the meeting is after hours.

I'm pleased to announce the release of RevisionManager 1.3 final. It fixes many bugs since the release candidate and adds support for ExternalMethods. Once again a big thanks to ZopeMag.com which has been sponsoring development since the beginnings. If you already have an instance of RevisionManager, please follow the instructions in the INSTALL.txt file, section 4 Upgrading. If you want to make use of the new property synchronization feature in your already existing RevisionManager setup, please read INSTALL.txt, section 5 Properties. I am also pleased to announce the release of RevisionObjects. This is a Zope product which adds a new tab called 'Versioning' to the most common Zope objects that can be revision controlled with RevisionManager. In this tab, you can execute most common CVS actions on this object without having to constantly switch between the object's management screens and your RevisionManager.

DirectoryStorage 1.1.2
by Toby Dickenson 18 May '03

18 May '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Announcing the release of DirectoryStorage 1.1.2 A serious bug has been discovered in all previous versions. Version 1.1.2 contains a fix, and no other changes. All users are encouraged to upgrade at their convenience. Problem Details: Under high write pressure it was possible for DirectoryStorage to neglect to flush all necessary files into the main storage directory when entering snapshot mode. This could happen if a transaction is committed concurrently with entry to snapshot mode. The effects of this bug include incomplete backups, incomplete replicas, and spurious errors when packing. Mitigating factors: 1. This does not corrupt the main storage, although it can lead to corrupt backups or replicas. 2. The corruption will certainly be detected by checkds. You do run checkds on a snapshot before taking a backup, dont you? 3. A backup/replica may be corrupt due to a missing file. Any missing file will certainly be included the next backup/replica. 4. I believe that the problems with backup and replication cant happen when the storage is inside a ZEO server, thanks to ZEO's threading architecture. DirectoryStorage inside ZEO is still vulnerable to spurious errors when packing. Download: http://sourceforge.net/project/showfiles.php?group_id=53818&release_id=1600… This bug was detected using a recent unit test added to ZODB by Jeremy to test a FileStorage corner case. Anyone wanting to repeat these unit tests will need the CVS trunks of both projects. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQE+x6bf99Pa/DbwZfsRAhQ9AJwMnVad/0hrM+iOPUEvRKTADB3ODwCeODV+ gBx4bwjiXETZRmxEpKrkz+Q= =OTzE -----END PGP SIGNATURE-----

by Philipp von Weitershausen 17 May '03

17 May '03

I'm please to announce the first (and hopefully only) RevisionManager 1.3 release candidate. RevisionManager is a CVS frontend product for Zope. It brings the power of revision controlling to the ZODB. New in Version 1.3: Properties can now be synchronized through CVS. They are written to extra files named .<id>.properties where <id> is the ID of the object. A plug-in architecture makes it possible to write property adapters for nearly any Zope object; adapters for OFS.PropertyManager (DTML Document, PageTemplate, File, Image), DTML Method and SQL Method are included. If you already have an instance of RevisionManager, please follow the instructions in the INSTALL.txt file, section 4 Upgrading. If you want to make use of the new property synchronization feature in your already existing RevisionManager setup, please read INSTALL.txt, section 5 Properties. You may download RevisionManager at: http://www.zope.org/Members/philikon/RevisionManager Philipp

Zope 2.6.2 Beta 1 Released
by Matthew T. Kromer 14 May '03

14 May '03

ZOPE 2.6.2 Beta 1 Released Zope 2.6.2b1 represents a development step in the next Zope release formed with a large number of community contributions. You may download Zope 2.6.2b1 from Zope.org: http://www.zope.org/Products/Zope/2.6.2b1/ 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 2.6.2b1: * 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, 683, 814, 816, 875, 892 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/2.6.2b1/CHANGES.txt * http://www.zope.org/Products/Zope/2.6.2b1/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/
