22 Mar '00

G'day, Zope Weekly News is a digest of some of the useful and interesting events which have occurred on the various Zope mailing lists and the Zope.org site. It is published each Wednesday before Noon. Any opinions contained in the Zope Weekly News are those of the chronicler exclusively. Announcements * Two new Zope revisions were released this week. 2.1.5 filled in security holes which affected sites which allow untrusted users to create DTML documents. Ironically, a bug-fix which was included in 2.1.5 broke code which depended on the bug. This was fixed in the second release, 2.1.6. http://www.zope.org/Products/Zope/2.1.5/Zope_215_release http://www.zope.org/Products/Zope/2.1.6/Zope_216_release * Thanks to Eduardo Fernandez Corrales, the Zope Weekly News is now available in Spanish! He is publishing translations at Zope Hispano, a portal for Spanish-speaking Zope developers and users. http://zope.sistelnet.es * Healtheon | WebMD is hiring in Atlanta, GA Healtheon | WebMD is looking for Software Engineers with experience in Python and/or Zope to work in our Global News Center located in Midtown Atlanta, GA. You must be willing to relocate. http://www.zope.org/Members/kbirch-webmd/hiring-notice New Products * The Portal Toolkit has been packaged into a snapshot release for use by those who do not have access to CVS. The PTK is targeted at community-oriented portals, but is also appropriate for any site which wants to give members a personalised view of content. The snapshot release is 0.7.1. http://www.zope.org/Products/PTK Updates * Software Product: load_site.py with additional features, by Itamar Shtull-Trauring Itamar has updated his powered-up 'load_site.py' again. The present release is 1.3.1. This update adds a GUI, built with wxPython. 'load_site' is a utility for dumping content from a file system into the ZODB. http://www.zope.org/Members/itamar/load_site * Software Product: ZopeEDIT, by "jimbag" The latest release of this product, 0.0.5, adds limited RPC support which is used to create and delete folders. ZopeEDIT is a tool which enables any text editor to edit content on a live Zope server. It does not need to run on the same machine as the Zope server. http://www.zope.org/Members/jimbag/ZopeEDIT/ * Software Product: LocalFS, by Jonothan Farr Version 0.1.6, the Ides of March release, fixes several bugs, is more robust about determining file types, and creates XMLDocuments and StructuredDocuments automatically, where appropriate. LocalFS is a product which allows Zope to serve files out of a local filesystem. http://lists.zope.org/pipermail/zope-announce/2000-March/000130.html * Software Product: SiteAccess, by Evan Simpson Evan has release version 1.0.1 of SiteAccess. This version fixes a bug which interfered with FTP access to Zope. The SiteAccess product allows Zope to serve different content depending on the hostname the site was accessed by. http://www.zope.org/Members/4am/SiteAccess Zope.org items * How-To: VersionFTPServer, by "htrd" This How-To describes modifications to Zope which allow you to work within a Version through FTP. Versions allow you to stage changes to a Zope site by effectively forking the database. Changes that you make in a Version are not publicly visible until you ask them to be. http://www.zope.org/Members/htrd/howto/VersionFTPServer * How-To: How To: Use GenericUserFolder with an SQL database Version 1.1, by "hippy" This How-To shows how to customise GenericUserFolder(GUF) to use an SQL database as its repository for usernames, passwords, roles and anything else you want to store about a user. The update adds information from Dennis Baker to help get things going with MySQL. http://www.zope.org/Members/hippy/GUF_SQL_crypt_1_1 -- Mike Pelletier.

ANN: 4XPath 0.8.3 and 4XSLT 0.8.3
by Uche Ogbuji 17 Mar '00

17 Mar '00

Fourthought, Inc. (http://Fourthought.com) announces the release of 4XSLT and 4XPath 0.8.3 ---------------------- A python implementation of the W3C's XSLT language 4XSLT is an XML transformation processor based on the W3C's specification for the XSLT transform language. 4XPath implements the W3C XPath language for indicating and selecting XML document components. http://www.w3.org/TR/xslt 4XPath implements the full 4XPath recommendation except for the 'lang' core function. Currently, 4XSLT supports a sub-set of the XSLT recommendation including the following: Full expression support and attribute-value template expansion xsl:include xsl:import xsl:template xsl:apply-imports xsl:apply-templates xsl:copy xsl:call-template xsl:if xsl:for-each xsl:choose xsl:element xsl:when xsl:attribute xsl:otherwise xsl:text xsl:message xsl:value-of xsl:variable xsl:processing-instruction xsl:param xsl:comment xsl:with-param xsl:strip-space xsl:key xsl:preserve-space xsl:copy-of xsl:sort xsl:namespace-alias xsl:output xsl:number and, of course, xsl:stylesheet, xsl:transform, literal elements and text Using the xml output method, 4XSLT produces the result tree by throwing events from the emerging SAX 2 standard to a handler, so it can be easily modified to supply results to any SAX 2 consumer. For the 'html' and 'text' output methods special SAX consumers produce HTML DOM nodes and plain text respectively. Note: 4XSLT and 4XPath cannot work with JPython. News ---- Changes in 0.8.3 ---------------- - _Major_ performance improvement (by indexing for document order) - Add XPath API for document-indexing optimization - Implemented xsl:number - Properly wrap exceptions and fix pseudo-i18n - Plug memory leak with RTF variables and params - Fixed document() function - Fixed bugs in apply-templates - A profusion of bug-fixes More info and Obtaining 4XPath and 4XSLT ---------------------------------------- Please see http://Fourthought.com/4Suite/4XPath http://Fourthought.com/4Suite/4XSLT Or you can download 4XSLT from ftp://Fourthought.com/pub/4Suite/4XPath ftp://Fourthought.com/pub/4Suite/4XSLT There are Linux RPMs available at ftp://Fourthought.com/pub/mirrors/python4linux/redhat/ 4XPath and 4XSLT are distributed under a license similar to that of Python. -- Uche Ogbuji Fourthought, Inc., IT Consultants uche.ogbuji(a)fourthought.com (970)481-0805 Software-engineering, project-management, knowledge-management http://Fourthought.com http://OpenTechnology.org

ANNOUNCE: omniORB for Python pre-release 2
by Duncan Grisby 16 Mar '00

16 Mar '00

AT&T Laboratories Cambridge is pleased to announce that the second pre-release of omniORBpy is now available for download. omniORBpy is a robust and efficient implementation of the CORBA Python mapping. The most significant update from pre-release 1 is that omniORBpy now has full POA support, when used in conjunction with omniORB 3 (which is also in pre-release). omniORBpy can also be used with omniORB 2.8, in which case most POA functions are disabled. We run omniORBpy on Linux, Solaris and Windows NT, and it has already been ported to a number of other platforms. It should be easy to port to any other platform for which omniORB and Python are available. Although this is a pre-release, the ORB has no known bugs, and is in daily use in our lab. omniORBpy is only available in source form at the moment. Binaries will follow in the near future. For further details, and download instructions, visit http://www.uk.research.att.com/omniORB/omniORBpy/ Enjoy! -- -- Duncan Grisby \ Research Engineer -- -- AT&T Laboratories Cambridge -- -- http://www.uk.research.att.com/~dpg1 --

16 Mar '00

G'day, Zope Weekly News is a digest of some of the useful and interesting events which have occurred on the various Zope mailing lists and the Zope.org site. It is published each Wednesday evening. Any opinions contained in the Zope Weekly News are those of the chronicler exclusively (but I'm willing to share). Announcements * The latest versions of the Zope Content Managers Guide, Z SQL Method User's Guide and DTML Reference Guides is available in postscript(ps) format. With luck, the technical problems of the previous versions have been fixed. http://www.zope.org/Members/Pam/PSversion * Check out the new Zope Documentation Projects page that lists current Zope documentation projects and their status. http://www.zope.org/Documentation/Projects/Projects * Martijn Faassen <faassen(a)vet.uu.nl> has established a Zope-XML mailing list. The intent is to discuss Zope's XML infrastructure. http://www.egroups.com/group/zope-xml/info.html New Products * Software Product: iTrack Issue Tracker Product, by "shalabh" iTrack allows a team of people to keep track of various issues about a project. Currently this is in development stage (Version 0.2.0) but usable, as long as you follow the instructions. http://www.zope.org/Members/shalabh/iTrack/ * Software Product: ZGDChart Product, by "teyc" ZGDChart uses gdchart to draw charts. This product comes with Windows binaries and source for non-Windows platforms. This initial development release is 0.3. http://www.zope.org/Members/teyc/ZGDChart * Software Product: DTMLTemplate, by "halazar" DTML Templates are documents that allow blocks of text to be named and made available to other documents. The basic building block of templates is the DTML block tag, which can also be used with other DTML document types. Templates export their blocks. Another new tag, the suppress tag, allows block definition without rendering. http://www.zope.org/Members/halazar/Products/DTMLTemplate Updates * Software Product: jcNTUserFolder, by Jephte CLAIN This product authenticates Zope users against an NT domain controller. All users are encouraged to upgrade to this version, 0.0.3. Unfortunately, the upgrade is incompatible. You will lose any role settings. http://www.zope.org/Members/jephte/jcNTUserFolder Zope.org items * How-To: The Debugger Is Your Friend, by Michel Pelletier This HowTo is an invaluable resource for those days where if I get one more mysterious traceback, just one more and I swear I'll crack. It explains how to step through Zope code line-by-line with the python debugger. http://www.zope.org/Members/michel/HowTos/TheDebuggerIsYourFriend * How-To: How to test your products without (re)starting Zope, by "teyc" This HowTo describes testing Zope products within a python interpreter without starting the Zope server. This rather speeds up the code-test-curse-code cycle, because it allows you to quickly reload your Product with each change. http://www.zope.org/Members/teyc/howtoProductTesting -- Mike Pelletier.

telnetnvt.py
by Mike Howard 13 Mar '00

13 Mar '00

I've completed a `first cut' at a telnet class. This is not a replacement for telnetlib.py, but could serve as a base class for it. See: http://www.clove.com/downloads telnetnvt.py is a python module which implements:Download telnetnvt.py RFC 854 - basic Telnet Protocol RFC 856 - Telnet Binary Transmission RFC 857 - Telnet Echo RFC 858 - Suppress Go Ahead RFC1372 - Flow Control It is not (yet) a replacement for telnetlib.py which is included in the Python 1.5 distribution. The differences are: telnetlib.py does not implement options - telnetnvt.py does and provides a method to add additional options - either directly or by subclassing telnetlib.py does not require threads, whereas telnetnvt.py currently does. This will be fixed RSN -- Mike Howard <mike(a)clove.com>

by Andy Dustman 11 Mar '00

11 Mar '00

HyperText 1.0.0 --------------- light-weight HTML document generator The HyperText package is a light-weight (small and fast) HTML document generator. It is much smaller than HTMLGen, though it lacks some features. It implements a full HTML 4.0 element set and several base Document classes for different environments. This code has been used in regular production for more than a year without any changes whatsoever, and should be considered a stable release. Documentation is in the source. If you don't agree that the source itself is a work of art, return it for a full refund; note that this is free software, so send all returns to /dev/null.

by Harry Henry Gebel 10 Mar '00

10 Mar '00

PyNcurses v0.1 -------------- New Ncurses binding for Python PyNcurses is a new Python binding for ncurses, generated with the help of SWIG. It includes the curses, panel, menu, and form libraries. PyNcurses has now reached the point where I am able to use it, but if it is to truly improve I need input from other users, so I would appreciate it if anyone interested in using ncurses with Python would download the package and give me any suggestions that you think would help to make it better.
