Hi ya all, You wanna see what Squishdot can do/looks like? Bill Anderson has put up a Squishdot demo site. Its available here : http://www.libc.org/Community He also generously provided a test page containing the Squishdot default configuration (i.e. what it looks like right after installation). Its available here: http://www.libc.org/BlueHeaven Lastly, I just wanted to announce that Squishdot is now also available thru Zope's Contributed Products page at the following url : http://www.zope.org/Download/Contrib Cheers, Butch === Butch Landingin Squishdot maintainer http://members.tripod.com/squishdot/index.html squishdot(a)yahoo.com _________________________________________________________ Do You Yahoo!?

I confirm it's working as Steve told us.

The only problem I've found is that you can't authenticate with IE4. Netscape works great.

(it *is* fixed in Zope2 isn't it?) Uhhmm... no. This problem is a bit more complex than it sounds. First off, a 'Not Found' error (404) comes about because what you're looking for is not in the object database, thus, the error is not raised *in* the object database, but in ZPublisher, the ORB (unlike, for example, a DTML error). Due to the (very intentional) modularity of ZPublisher, ZPublisher can't just assume that there is a standard_error_message object in the object database (you can use ZPublisher by itself without Zope) so imagine it raising a 404, looking for standard_error_message, which raises a 404 which... Furthermore, ZPublisher is protocol independent. If you wanted to write, say, an NNTP protocol extension to ZPublisher, you could publish your objects as newsgroups and items (sick!). Or IMAP, or XML-RPC (which Eric Kidd is working on as we speak) or CORBA, or whatever, pick your protocol. The problem is, standard_error_message doesn't make any sense in those contexts, or maybe it does? Jim has presented a proposal for fixing this, and a few other things about our error model, for example, if you impliment error handling in the ORB like his proposal, it will no longer be necesary for the object database to grab its own errors, it can just let them float up to the ORB and then use the new method to find and call standard_error_message. This could be a 2.0 feature, if we can find the resources (I beg of you to volunteer ;). -Michel > tone. > ------ > Dr Tony McDonald, FMCC, Networked Learning Environments Project > The Medical School, Newcastle University Tel: +44 191 222 5888 > Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2 > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

Time fields in MSSQL/ODBC (urgent!)
by Jay, Dylan 15 Jun '99

15 Jun '99

A better solution to your problem is to replace the DateTime.py file at 664 with the following. I havn't tested it thoughly but it works for me. I'll see if I can get this in the base otherwise anyone who's timezone hasn't been explicitly defined will suffer from the same fustration. except: try: t= time() localzone = mktime(gmtime(t)) - t localzone = int(round(-localzone/(60*60))) if (localzone >=0): localzonename = '+'+str(localzone) else: localzonename = str(localzone) _localzone = _cache._zmap[lower('GMT'+localzonename)] except: _localzone=''

I remember getting a similar error awhile back on a CVS version of Zope. The reason was that I forgot to set the DNS_IP in z2.py.

Also, ZServer is currently multi-threaded, but there is no theoretical limitation to making it multi-process, in which each Zope instance will have it's own Python and thus it's own global Python lock, thus giving the OS the ability to schedule multiple processes among multiple processors, a little heavier than threads on multi-processor, but *vastly* easier to impliment and far more stable. > Do I misunderstand anything. > > Would Zope be appropriate for these situations?

Barnes and Noble > was talking > about beta-testing an 8way server to speed up their searches. 'Searching' is a whole nother question. If n Zope *processes* are all doing a search through the index at the same time and you have n processors, then each process will complete the operation without blocking each other, if multiple threads do it, then they will block each other. However, multiple processors will not speed up the time it takes to do *one* search, it will just allow multiple searches to be done concurently (which in high load situations makes each individual search look much faster). Getting into the ability break a searching algorithm down into multiple processors is complex and probably only pays off when your talking about searching through *massive* quantities of data. I mean big. If you had a Zope index with one million entries in it, you would, worst case, have to go through 20 comparison operations to find the element your looking for (Zope indexing uses a very efficient binary tree structure to store it's indexes). > > Now I understand that different development models yield > different results > and I don't know how Barnes and Noble's website is built.

SEMI-ANNOUNCE: Zpdf v0.1 a PDF dynamic document generator
by Pavlos Christoforou 15 Jun '99

15 Jun '99

Hello Zopistas - I have uploaded on my starship account http://starship.python.net/crew/pavlos/ the first stable version of a simple PDF document formatter. It comes with a minimal HTML to PDF converter that supports enough HTML to convert most StructuredText documents. (See Acquisition.pdf in the doc directory). Unfortunately it is too slow to become the basis of a Zope product but it was designed with that goal in mind. If the ZDP folk use well structured html (or just StructuredText) to write the ZDP documents and FAQs we will easily have a relatively good quality documentation ready with not too much effort. Included in the distribution is a patched version of StructuredText.py, which fixes some minor bugs. Pavlos
