Come kick some tires, at new.zope.org
by Martijn Pieters 10 Oct '01

10 Oct '01

Hi all, As some of you may know already, we've been hard at work building a new iteration of the Zope.org community website, one based on the CMF. This is an invitation to come and have a look at what we are doing for the new Zope.org server, and have a good kick at the tires. The idea is to get solid feedback from the community to iron out all the wrinkles and bugs that undoubtedly will be in there. You can find the server at: http://new.zope.org/ Please note however, that this is an early preview, and there are several known issues: - If you had a login on Zope.org about 2 months ago, chances are that you won't have to create a new account on new.zope.org; the LDAP database backing the site uses a 2-month old export. If you changed your password but not your email address during this time, the server can email you your password for the new server. If both changed, please email webmaster(a)zope.org for assistance. When we officially switch over, a new export will be created. - Because the current www.zope.org/dev.zope.org combination uses domain-wide cookies (.zope.org) and an incompatible session key, you cannot be logged into www.zope.org if you want to log into new.zope.org as well. Either delete the .zope.org cookie, use the 'Log out' link on www.zope.org, or use a different browser for each site. - Don't make any important changes or new content on new.zope.org and expect them to be retained. All changes to content on new.zope.org will be ignored the next time we migrate over content from the current site. Please file all bugs you find in the new.zope.org tracker at: http://dev.zope.org/Projects/nzot Thanks, and have fun! -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

ZOQL Method 0.3.0 released
by Stephan Richter 09 Oct '01

09 Oct '01

Hello everyone, Yes, it is me... again. I was on the role today and implemented a couple more features: 1. I added support for ALTER. You can now add, rename and delete properties from ZClass objects and any sort of other object instance, that supports the standard Property Manager or Property Sheet interface. 2. I added a XML-RPC-friendly execution method to the ZOQL Method class, which allows us to use the ZOQL Method as a server component, since you can send new commands directly to the interpreter. 3. Based on the XML-RPC support, I wrote a complete Command Line Client. You can use the client to execute queries from a file or use the interactive command line, similar to the PostGreSQL and Python interactive interpreter. There is also a nice help coming with the product. It can be run totally independent of the rest of the ZOQL Method, since it does not depend on any of the other modules. I also created a ** Mailing List ** and prepared a ** Poll **, where people can tell me what they think about the product! Please send me everything, good or bad!

ZOQL Method 0.2.0 released
by Stephan Richter 08 Oct '01

08 Oct '01

Hello everyone, I am very pleased to announce the initial release of ZOQL Method, version 0.2.0! What does ZOQL stand for? As you might have guessed, ZOQL stands for Zope Object Query Language. What does it do? With ZOQL you can query through the ZODB and retrieve objects, as you might be used to from SQL. Other statements, such as INSERT, CREATE, UPDATE, DELETE are supported as well. I hope to implement the ALTER statement soon. For more details on the language go to: http://demo.iuveno-net.de/iuveno/Products/ZOQLMethod/Documentation. The online help has also the reference as well as a nice and long example. Does the ZOQL try to compete with the ZCatalog? No, not at all! In fact, ZOQL uses the ZCatalog to implement its Indexes. Yes, ZOQL can use a ZCatalog for queries, instead of walking through the tree itself. Can I create Classes with ZOQL? Yes! You can create Products and put Classes into it. This is in particular useful for making temporary classes quickly. Later it will also serve as a method to generate Products from Case Tools like ObejctDomain. At the moment only ZClasses are supported though. Does it implement any standard? No! Back in May, when I first thought about ZOQL, I looked at many of the current so-called "standards". At the end, there were basically three choices left. Use (1) XPath/XQuery, (2) OQL/OCL or (3) implement a new language. Well, while XPath is okay, it really does not support any object manipulation and XQuery's syntax on the other hand is unacceptable for a Python programmer in my opinion. The OQL/OCL is supposed to be THE official standard for object-oriented query languages; yeah right, after reading a good chunk of the specs it was so obvious that it was horribly Java-bias, having three different data structures for a simple list... Well, so I was left with choice number 3. So I wrote down the original language reference and tried to keep it as close to SQL as I could. But the next task was to write a parser. This was the end of the project, until Thomas Foerster used Aaron Watter's kwParsing engine to implement the basic parser last month. Thanks a lot for the work! He gave the entire language a Pythonic twist by copying large parts of the Python Language Reference. :-) I finally got around to implement the product this weekend. If you feel like sending me a hate mail right now, please send it to srichter(a)cbu.edu! Did you get interested? The main URL is http://demo.iuveno-net.de/iuveno/Products/ZOQLMethod, but you can also find the files on Zope.org at http://www.zope.org/Members/srichter/Products/ZOQLMethod. Please feel free to send me any ideas, thoughts, comments, criticism, bugs and patches to srichter(a)cbu.edu! Regards, Stephan PS: ZOQL is pronounced 'So cool!' :-) -- Stephan Richter CBU - Physics and Chemistry Student Web2k - Web Design/Development & Technical Project Management

by Martijn Faassen 05 Oct '01

05 Oct '01

Hi there, I'm busy releasing today! I've just released the initial version of XPath Methods, arbitrarily set at 0.7. XPath Methods is a Zope product that glues FourThought's 4XPath to ParsedXML, so that you can send XPath queries to ParsedXML XML documents. XPath is a language for addressing parts of an XML Document in a standard way. It is described in this W3C recommendation: http://www.w3.org/TR/xpath You can find XPath methods and documentation here: http://www.zope.org/Members/faassen/XPathMethods Unfortunately the installation instructions are copious.. Sharpen your compiler! XPath Methods also comes with online help. Regards, Martijn

05 Oct '01

Hi everybody, I've just released Formulator 1.0.9. It includes a new TALES tab that allows you to more flexibly override field properties. To use the TALES tab you need to have Zope Page Templates installed, though Formulator continues to work without this requirement as well. You can find Formulator here: http://www.zope.org/Members/faassen/Formulator Regards, Martijn

Re: [Zope] Core Session Tracking 0.9 Released

CST is still on track to be incorporated in 2.5. This is a release for folks who don't want to go to bleeding edge 2.5 (folks who are currently using CST under Zope 2.3.2 - 2.4.1) as soon as it comes out. Michael R.

Core Session Tracking 0.9 Released
by Chris McDonough 05 Oct '01

05 Oct '01

Hi Folks, A new version of the Core Session Tracking product (the first one in six months!) has been released. Core Session Tracking is a Product which allows you to easily associate transient data with anonymous users. The product is available from http://www.zope.org/Members/mcdonc/Products/CoreSessionTracking. To upgrade from prior releases, just remove the "old" CoreSessionTracking product directory and install this one as per the install instructions in the help/CoreSessionTracking.stx document. A list of changes since the last version is: - Took advantage of securityinfo module and new BTrees modules. As a result, CST 0.9 is incompatible with releases of Zope prior to Zope 2.3.2. - Objects are now acquisition-unwrapped before being placed into session storage (thanks to Matt Hamilton) - A SessionData object's __setitem__ may now be called from a Python Script, it failed previously with a security error. - Fixed bug in SessionDataManager security assertions which made it impossible to change security parameters (thanks to Uwe C. Schroeder). - Fixed constructor number of parameter bugs (thanks to Chris Withers). - Fixed bugs that made isTokenFromForm, isTokenFromCookie, and isTokenNew methods virtually useless (thanks to Frank Tegtmeyer). - added flushTokenCookie method, which deletes the token cookie from the client browser with prejudice. This method is useful when you want to start out completely fresh with a different token. - Fixed bug which caused a "TypeError: loop over non-sequence" at startup under Zope 2.4.X in the Interfaces module which caused the product to not be initialized properly. (Thanks to Chris Withers and Joachim Werner). - Added multithread test cases to testSessionDataManager. - SessionFanout _getleaf method made more efficient by making allowed_hashes a dictionary (thanks to Anthony Baxter). - Added 'getName' alias to SessionData's 'getId' method for compatibility with code written for SQLSession (thanks to Anthony Baxter). - SessionDataContainer keys are now required to be strings (thanks to Anthony Baxter). - Added a new method to SessionDataManagers, "getSessionDataByKey", which provides a way to obtain an arbitrary session data object by feeding it a key (as opposed to getSessionData, which always obtained the session data object related to the current token). A user needs to possess a special permission to be able to do this. - Added conflict resolution to (RAM-based, internal) SessionStorage. - Made internal data container use "LowConflictConnection" class for its ZODB connections. This class operates differently than the standard Connection class because it doesn't raise "read" conflict errors. - Removed "AutoExpireMapping" class and merged its functionality into SessionDataContainer. - Removed "SessionFanout" module (unecessary because we're not trying to support pre-2.3.2 Zopes). - Refactored tests slightly. - Added SessioningPermissions and common modules.
