Pound sign in object id causes dtml-tree problem
by Richard Moon 28 Apr '00

28 Apr '00

I thought I'd pass this on. I have a simple dtml-tree which shows dtml-documents inside folders. I found that if I use a UK pound sign (£) in the document id then I get a problem - the document shows in the tree but I get a not-found error when trying to open it.

Re: [Zope] A nice problem with url_quote_plus

Hi. > Would I be correct in assuming what you'd like to do is: > > <dtml-call "RESPONSE.redirect(<dtml-var "_.string.join([url,query],'')" url_quote_plus>)"> > > If the syntax were allowed? (which unfortunately, it doesn't :( ) I known that it is not possible to use. My goal is to "quote_plus" a string ( a variable ), without using an External Method, to future use in my DTML Method. Is it possible? > There must be a simple way to do this, but I can't think of it :S I've read some source code form Zope, but my feeling is that task is impossible to complete without an External Method. Does any one have more opinions about it? TIA, @687, Nbk

Trinkets
by Jason Spisak 28 Apr '00

28 Apr '00

Zopists, I am working a bit more on the wizard thing. I've been trying to find the Trinkets/REQUEST/Form processing in the source and can't see it. 1. Is there a way to access the trinket from the request? ie. <dtml-var "REQUEST.form.trinkets"> 2. If not, does anyone know where that sucker is or what it's called? All my best, -- Jason Spisak 444(a)hiretechs.com

index_html
by Tom Deprez 28 Apr '00

Hi, Is it a good way to create an index_html inside a ZClass? Or is it better to not provide this method, but handle the view of a ZClass through the index_html of a folder? Tom.

ZODBCDA and Access 2000
by Andrew Williams 28 Apr '00

28 Apr '00

When I first started with Zope I was pulling information out of a temporary mySQL database for experimentation and putting it into a <table>. Everything worked fine for the database fields which had null values <dmtl-var field1 null=" "> I then downloaded ZODBCDA to start pulling off of an Access 2000 database which has the live data I need to display. I ran across a curious bug/feature? in regards to ZODBCDA and Access 2000. When I use the <dtml-var field1 null=" ">, Zope wouldn't recognize null values from Access. I checked and double checked that the field values were actually null in Access. I ended up having to switch my dtml-method to: <dtml-if field1> <td align="center"><dmtl-var field1></td> <dtml-else> <td>&nbps;</td> </dtml-if> instead of the old way. Is this a problem with ZODBCDA, Access, or better yet me? I know Access is not the database I should be using for the data, but one thing at a time.

Re: [Zope] Tomcat Vrs Zope Round Two (ding, ding)
by Andrew Williams 28 Apr '00

These are some very interesting results. Great job in creating/running these test. When you are finished, can you write a FAQ/paper on your results? This would be some good info for those of us trying to get Zope into corporations. Andrew -----Original Message----- From: J.

It is, though, a test of what Zope + Tomcat can do in terms of static performance. __________________________________________________________________________ Visit http://www.visto.com/info, your free web-based communications center.

Any way to use XSL with Zope?
by Bart Holthuijsen 28 Apr '00

28 Apr '00

Hello fellow XML-Zope enthusiasts! I'm working on a project to make technical documentation available over the internet. The documents are in Word format now, but we plan to convert them to XML. I have already converted a few documents and made a XSL stylesheet. I can use this stylesheet to render HTML files on the command line with Xalan, but I'm not limited to this or any other XSL processor. I had a look at XMLDocuments and XMLWidgets, but this is just a different approach, right? I'd like to make use of XSL and have also seen discussions about integrating XSL with Zope.but unfortunately it isn't yet. Does anyone have any experience with this? Thanks in advance, Bart Holthuijsen. ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Tomcat Vrs Zope Round Two (ding, ding)
by J. Atwood 28 Apr '00

28 Apr '00

Ok, so I heard back from a few people yesterday talking about how the test was just serving static content and therefore is not really a "true" test. It is, though, a test of what Zope + Tomcat can do in terms of static performance. To be fair, I decided to have them do a basic "connect" to a database and see what would happen. Zope Machine: RH 6.1, 300 MHz, 256 MB RAM, 8 GB EIDE Drive - Zope. 2.1.4 Tomcat Machine: RH 6.1, 500 MHz, 512 MB RAM, 3 x 9.1 SCSI in RAID - Jakarta Tomcat 3.1 Both with PostGreSQL 6.5.3 installed from RPM. No modifications at all. The .jsp page just tests the database connection. If it can get to the database it returns a string. (I will include the source at the bottom). Ran this about 5 times here is the best. Document Length: 353 bytes Concurrency Level: 25 Time taken for tests: 9.354 seconds Complete requests: 100 Failed requests: 0 Total transferred: 75430 bytes HTML transferred: 35300 bytes Requests per second: 10.69 Transfer rate: 8.06 kb/s received Connnection Times (ms) min avg max Connect: 0 11 63 Processing: 120 2061 2959 Total: 120 2072 3022 I then modified my Zope test page by creating a ZSQL Method that just does a simple select (select name for table where id = '1000') No biggy. I dropped that into the test.html page and made it display the name. Here is what I got after five or so tests. Document Path: /test.html Document Length: 172 bytes Concurrency Level: 25 Time taken for tests: 2.857 seconds Complete requests: 100 Failed requests: 0 Total transferred: 37875 bytes HTML transferred: 17372 bytes Requests per second: 35.00 Transfer rate: 13.26 kb/s received Connnection Times (ms) min avg max Connect: 0 0 2 Processing: 63 627 800 Total: 63 627 802 While I am not being totally blown away by the results I am starting to get the big picture. I was also asked to try it against resin. Which I did last night and send the results. I tried it again this morning and while it would perform well in the first test it would die in the second test and need to be rebooted. Don't know what this is but will keep looking into it. Next? To create a cgi script, in Python to get the same data and run it on Apache. Now that could be interesting! Also would be to put Zope on the same machine, but for now,being 3 x faster on a slower machine is just fine with me. :) JMA Source of .jsp with some HTML removed. <%@ page language="java" %> <%@ page import="savant.server.beans.GSSessionBean" %> <%@ page import="savant.server.util.GSUtil" %> <jsp:useBean id="sessionBean" scope="session" class="savant.server.beans.GSSe ssionBean" /> sessionBean.setDBDriver("postgresql.Driver"); sessionBean.setDBURL("jdbc:postgresql://localhost/gs1"); sessionBean.setDBUserID("userid); sessionBean.setDBPassword("usernam"); <%= sessionBean.gstest() %>

mod_pcgi2 location related problem
by Oleg Broytmann 28 Apr '00

28 Apr '00

Hello! I have solved (at least partially :) the puzzle with location-related problems in Apache. When you create config like this <Location /pcgi/some> and go to URL like /pcgi/some/path, Apache thinks only /pcgi is location, and /some is a part of path; PATH_INFO in this situation will be /some/path instead of /path - and that, of course, leads to error 404. I wrote a code to overcome this Apache strangeness. I need your help to test it. If anyone willing to test - mail me and ask for the new code. It is highly experimental, and couldn't be used on a production server. Be warned! Don't know whether this would fix the problem with <Location /> - I'll do some testing here, but please report your results, too. Oleg.
