DTML methods title
by Petru Paler 19 Jul '99

19 Jul '99

How can I set a title to a DTML method ? It always gets the title from the calling object, which is normal, but there are some things (such as Catalog search results) which have to be done as methods and getting the folder title isn't a very nice thing. -Petru

MySQLDA performance
by erikm＠islandnet.com 19 Jul '99

19 Jul '99

I have been doing some tests (admitedly incomplete and unscientific) with Zope and a MySQL database. Using ZServer to parse a simple page with one "included" file = 18 hits per second(hps). Using PHP3 and Apache to parse a like page with the same "inlcuded" file = 16 hps Using ZServer w/ a Z SQL method to display a table (select * from ) = 3 hps Using PHP3 and Apache to display the same table = 13 hps. Looking at the MySQL logs, they both keep a persistent connection. Why is it so much slower with Zope?They are delivering the exact same content with each request. The parsers are doing the same job at the surface, although I don't have a full grasp of what goes on beneith... As a parser, they are similar in speed, but with the database connection, ZServer falters. I tried starting ZServer with "-t 1" as I read in a previous post, but the result was similar. Testing done using Pounder II. erik myllymaki erikm(a)islandnet.com

'selection' and 'multiple selection' property types
by Alex Rice 19 Jul '99

19 Jul '99

Is there an example anywhere of how to use these? I am looking in ZPublisher/Converters.py (2.0a3) and they are not defined there. Are these property types not implemented yet? Alex Rice | alrice(a)swcp.com | http://www.swcp.com/~alrice Current Location: N. Rio Grande Bioregion, Southwestern USA

In Zope 2 you can do: <dtml-in "_.range(0, number_of_times)">  </dtml-in> The _.range method does everything the bog standard python range() does, but won't let you make a range that contained more that 999 elements (like range(0, 20000, 3)). -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

RE: [Zope] dtml question: xrange?

I see that Alexander answered the question, so I'll provide the answer to "Why not?" Zope tries to prevent people from resource attacks via TTW editing. One way that Jim Fulton worked pretty hard on was preventing people from creating huge sequences, such as with the range function(s). --Paul > -----Original Message----- > From: Alexander Staubo [mailto:alex@mop.no] > Sent: Sunday, July 18, 1999 7:28 PM > To: Zope Mailing List (E-mail); 'Kevin Lewandowski' > Subject: RE: [Zope] dtml question: xrange? > > > For this and any other operation not directly supported by the DTML > "API", you can write External Methods to provide the service.

Iterating over lists of tuples
by Alexander Staubo 19 Jul '99

19 Jul '99

Did I make a mistake in the following DTML?  <br>  It turns out that this will only print "1" and "2" -- not "('a', 1)" and "('b', 2)" as I expected. However, if I add a third item to the tuples, it works:  <br>  This prints out ('a', 1, 0) ('b', 2, 0) Now, that's not right, is it? (Verified with Zope 2.0.0a3.) -- Alexander Staubo http://www.mop.no/~alex/ "What the hell, he thought, you're only young once, and threw himself out of the window.

help urgently needed...
by Jens Vagelpohl 19 Jul '99

19 Jul '99

hi zope experts... i sent a message to the mailing list a few days ago about netscape and a  that refuse to work with each other. unfortunately, i haven't gotten any reply yet :( i need to get this solved before the project demonstration (i *know* my professor has netscape on his machine)... here's the situation: i have a "help" menu which is based on the tree tutorial included in the ZBook. i basically reused the same code and just renamed object references where needed. i have just one folder in the tree (called "How to...") and the folder contains DTML docs with IDs like "Use this help system" or "Search for a customer record" etc. everything displays and works fine with IE 4, IE 5, the StarOffice browser (SO 5.1), but *not* with netscape. i tested it on NS 4.51 on Linux as well as the Win32 version of Mozilla Milestone 8. expanding the book content in the navigation bar works fine so that i see all topics. but once i click on one of the topics ZServer restarts and netscape gives me something like "document contains no data". am i doing something wrong? or is it some bug in netscape? please help... Here is the code to link to the help topic pages (again, it's the very same used in that tutorial): <IMG SRC="/HelpSys/hs_dnode" ALIGN="TOP" BORDER="0" width=16 height=16> <A HREF="/?tree-s=&tree-e=&tree-c="></a> Here is the error trace that dumps onto my linux terminal window when ZServer goes down, it's always the very same message: uncaptured python exception, closing channel <zhttp_channel connected 192.168.168.3:4137 at 844fe00 channel#: 1 requests:0> (exceptions.TypeError:unpack non-sequence [/usr/src/Zope-2.0.0a3-src/ZServer/medusa/asyncore.py|poll|59] [/usr/src/Zope-2.0.0a3-src/ZServer/medusa/asyncore.py|handle_read_event|285] [/usr/src/Zope-2.0.0a3-src/ZServer/medusa/asynchat.py|handle_read|126] [/usr/src/Zope-2.0.0a3-src/ZServer/medusa/http_server.py|found_terminator|44 4]) Jens Vagelpohl
