Keep Alive Connection
by Matt Ficken 18 May '03

18 May '03

My product needs to send data to the client, and then later send the client more data, over the same connection. HTTP/1.1 created Keep-Alive connections for this reason. I tried setting the response header 'Connection' to 'Keep-Alive', but Zope closes the connection anyway. So, I made an infinite loop in the function that is called when the connection is first opened, which keeps the connection open. Within the loop, the sleep function is called to sleep for 1 second, otherwise Zope sucks up all my unused CPU cycles. But, after I get 2 or 3 of these loops going, the whole Zope server locks up. It won't accept any connections. Is there a different way I can keep connections alive without locking up Zope or using all the system's CPU cycles? -- __________________________________________________________ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup

Zope-2.6.1/Redhat9.0
by Andrew Jessup 18 May '03

18 May '03

Dear All, Has anyone heard of problems running Zope 2.6.1 on Redhat Linux 9.0 using ZServer/Python 2.1.3? Specifically, unstable web browsing unless running in single thread mode, particularly when accessing the management interface, and crashing when ZServer FTP is accessed (ie. through port 8021)? We have this problem, from an installation from the binary tarbell onto a clean installation of RH9.0 running on x86. If this is a common problem - is there a solution? Cheers, Andrew

Q/OT: How to Share Information across Organisations
by Bill Bell 18 May '03

18 May '03

Although this question is not about Zope per se, I'm sure that Zope offers some good ways of implementing solutions. I have just started creating a web site for the Ontario Suicide Prevention Network, as a volunteer. I have found quite a few organisations that offer information for people who are suffering great distress. However, there appears to be no central list that all organisations might share so that any individual finding one of the sites would be sure to obtain all available information, particularly about telephone distress lines. Would someone please suggest alternative ways of implementing a common list? I have been thinking in terms of providing some kind of RSS feed. How does that sound? Thanks for any help. Bill

dtml-sql case sens. issue
by Michael Dexter 18 May '03

18 May '03

Hello, I am experimenting with SQL under Zope and have started with the "Elvis Sighting" tutorial. I've created my own table with obvious names like "varcharField0" for the first field, which is a varchar. I used an uppercase "F" to make it a little easier to read. I understand that SQL is generally not case sensitive. Here's the SQL to create the table, the "stored procedure" to view all and the DTML snippet that calls it. The issue: <dtml-var varcharField0> BREAKS while "varcharfield0" works. Whose case sensitivity problem is this? Zopes? SQL's? The Browser? create table tutorial_table( varcharField0 varchar, varcharField1 varchar ) spViewAllRecords: select * from tutorial_table <dtml-in spViewAllRecords> <p>varcharField0 contents: <dtml-var varcharfield0></p> <p>varcharField1 contents: <dtml-var varcharfield1></p> </dtml-in> Thanks, Michael.

Synchronising when only FTP access is available
by Bill Bell 17 May '03

17 May '03

I have shared access to Zope where ZSyncer is unavailable. What do you think of a software system that would access Zope via the management interface for creating various kinds of objects as necessary and, at the same time, access Zope via FTP for transferring the contents of the objects from copies existing on another Zope site?

Acquistion mistery
by D2 17 May '03

17 May '03

Hello, i have three objects : testform (a ZPT) testscript (a PythonScript) testdtml (a DTML Method) located in a standard Zope root. I fill in testform fields then submit the form to testscript wich set a property (request.set('tesfield', 'Hi there') in the request and then calls testdtml with the request object. testdtml displays REQUEST with the fields from testform and testfield set in tescript, without problems if i don't use <dtml-var standard_html_header>. If i do, the publisher returns a KeyError : standard_html_header. I don't understand why standard_html_header is not acquired. Does somebody explain to me how acquisition behaviour is affected by my stuff. More generally, my goal is to understand how i can pass parameters to forms from scripts, other forms and object methods so don't hesitate to feed me with some theory. here is the source of testscript: # Example code: # Import a standard function, and get the HTML request and response objects. from Products.PythonScripts.standard import html_quote request = container.REQUEST RESPONSE = request.RESPONSE request.set('testfield','Hi there') destination=getattr(container,'testdtml') kw={} kw['REQUEST']=container.REQUEST return apply(destination, (), kw)
