Dreamweaver and _notes
by Chris Withers 11 Feb '00

11 Feb '00

Hi, I think this problem is best solved by modifying Dreamweaver, but since their news server is down I thought I'd ask here. I use Dreamweaver to edit the content of my Zope site. It works very well, including Dreamweaver's check in/check out stuff. It also has a system for keeping Design Notes associated with your files. Unfortunately, it chooses to store them in a folder called _notes on the server. Zope doesn't like folders that start with and _ so it doesn't work. In Dreamweaver, there is a file called FileClass.js which specified a constant that is '_notes.' However, changing this doesn't seem to affect Dreamweaver as it still tries to create the _notes folder. So, is there any way to ACTUALLY change this in Dreamweaver (like compiling the javascript of something) or is there any way to sort it out at the Zope end? cheers for any help, Chris

RE: [Zope] ZServer breakage wrt HTTP - 2.1.3

I develop ZopeStudio on straight ZServer, so I don't think that that is the problem. The 25 pings you see is ZopeStudio waiting for Mozilla to have retrieved and parsed the RDF, not actual data over the network. Look in your Z2.log file, in the var directory. You should see entries for "GET /zsTreeRoot HTTP/1.0" and "GET /zsContainerRDF HTTP/1.0". If they are not there, Mozilla cannot find your server. Thanks to some fixes from the Mozilla team, better error reporting is under way. > I retreived them without a hitch from within netscape > 4, but mozilla can't even get the main page from zope.

ZServer breakage wrt HTTP - 2.1.3
by Brett Morgan 11 Feb '00

11 Feb '00

I am playing with ZopeStudio on a stoke Zope 2.1.3 build (wo_pcgi) running ZServer on port 8080. It don't work. I uncomented the debugging dump at the top of the zopestudio.js file in the chrome and noticed that the server was just sending out 25 pings for the two rdf files it wants. I retreived them without a hitch from within netscape 4, but mozilla can't even get the main page from zope. So here's a theory: ZServer can't grok http 1.0 compliant request thus: [brett@localhost brett]$ telnet localhost 8080 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. GET http://localhost:8080/ HTTP/1.0 host: localhost:8080 HTTP/1.0 404 Not Found Server: Medusa/1.13 Content-Type: text/html Content-Length: 134 Date: Fri, 11 Feb 2000 15:04:23 GMT <head> <title>Error response</title> </head> <body> <h1>Error response</h1> <p>Error code 404. <p>Message: Not Found. </body> Connection closed by foreign host. But lives fine with this slacker http: [brett@localhost brett]$ telnet localhost 8080 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. GET / HTTP/None 200 OK Server: Zope/Zope 2.1.3 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Fri, 11 Feb 2000 15:05:25 GMT Content-Length: 1290 Content-Type: text/html <HTML> <HEAD> <TITLE>Zope</TITLE> <base href="http://localhost:8080/"> </HEAD> <BODY BGCOLOR="#FFFFFF"> ... which is not actually correct since I pinged it in http 0.9. No matter. Everyone of note communicates in HTTP/1.0ish. But Mozilla the standards compliant client that it is, breaks ZServer. I hope this helps the guys trying to figure out why ZopeStudio is breaking :) brett -- email: Brett.Morgan(a)uts.edu.au phone: +61-2-9514-2091 The rhino is a homely beast, For human eyes he's not a feast.

XML-RPC woes
by Tony McDonald 11 Feb '00

11 Feb '00

Hi all, I'm trying to get this to work **from a XXX PythonMethod** (ie the ones that allow you to import things and are coloured red and orange!) PythonMethod do_par import xmlrpclib server_url="http://xmlrpc.server:9999" server=xmlrpclib.Server(server_url) server.getTranscript(number) I call it with a dtml doc <form action="do_par" method=post> <input type=text name="number:int"> </form> The PythonMethod returns a blank page (whether from the form or the 'try' tab) If I make the PythonMethod be; import xmlrpclib def doit(number): server_url="http://xmlrpc.server:9999" server=xmlrpclib.Server(server_url) return server.getTranscript(number) doit(number) Then I get this error, when called from either the form or the 'try' tab.   I'd like to work from PythonMethods as they offer the promise of speedy editing, so what am I doing wrong this time? :( getTranscript does work, because all this code works from the Python interpreter. ta tone. ------ Dr Tony McDonald, FMCC, Networked Learning Environments Project http://nle.ncl.ac.uk/ The Medical School, Newcastle University Tel: +44 191 222 5888 Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2

HELP - Zope frequent restarts
by \Tony＠newtimes.com, Rossignol"＠newtimes.com, <tonyr＠ep.newtimes.com> 11 Feb '00

11 Feb '00

Hello everyone, Does anyone know of debugging techniques that are useful to diagnose zope restarts? We are running Zope 2.1.3 and once the load approaches 5 requests/second zope can't stay up more than 30 minutes. I am hoping that there is some code we wrote that is causing these "crashes" but I've found no way to track them down, since when traffic is low we don't appear to have the problem. Any help would be greatly appreciated. Is this something we should be looking at ZEO for 5 hits/second? I was under the impression Zope could handle much larger loads than this. -- ------------------------------- tonyr(a)ep.newtimes.com Director of Web Technology Newtimes Inc. -------------------------------

Database transaction
by Matt Goodall 11 Feb '00

11 Feb '00

Hi, When adding to a database table I need to calculate the next number from the existing records, increment that number and add the new record using the calculated number. The critical thing is that the transaction must be uninterrupted or two or more users could be assigned the same number. Can this be done with the Zope database connections? I'm using MySQL at the moment but I could (presumably) change to PostgreSQL quite easily. Any other ideas would be more than welcome. Cheers, Matt. -- Matt Goodall | Isotek Electronics Ltd email: mgg(a)isotek.co.uk | Claro House, Servia Road Tel: +44 113 2343202 | Leeds, LS7 1NL Fax: +44 113 2342918 | England

Re: [Zope] Calling a ZSQL methods from an external method

The external method takes > self as an argument, and in the code I just call self.sqlMethod(). Okay, I've got that, except that I have a single extension in that my ZSQL method takes an argument. I'm trying to call it ala: results=self.GetCat (CatID=str(catID)) where "GetCat" is the SQL Method. So my external method reads: def CategoryPath (self, baseURL, catID): while (catID != 0): results=self.GetCat (CatID=int(catID)) This isn't working. I can't tell you if its the argument that's the problem, as the manifestation is that it can't find the right DB connector. -- J C Lawrence Home: claw(a)kanga.nu ----------(*) Other: coder(a)kanga.nu --=| A man is as sane as he is dangerous to his environment |=--
