zope-2.6.1+zeo-2.0.2 not trouble

hi since upgrading zope from 2.5.1 + zeo1, i've been having frequent zope/zeo client hanging/not responding. the setup: we have zope-2.6.1-src + zeo-2.0.2 on linux with python 2.1.3 frequently, the zeo client hangs/not responding. output of ps axf is below[1] and the stupid.log[2] Also, nothing much in ZEO_EVENTS.log[3] telnet localhost 8080 GET / HTTP/1.0\n\n resulted in nothing. no time out, nothing running ./stop will only kill the parent process, i.e 17160 in the below example. the other processes can only be killed with a kill -9 17161. restarting the zeoclient will make it respond again. i've tried zeo2.1a1( iirc) and the behaviour is the same i used to run with persistent zeo cache (ZEO_CLIENT=12000) in the ENV, but running without is still the same. i've also tried runnin with -Z1, and -Z- also the same behaviour thanks for any help/pointers ------ ps axwf [1] # ps axf|grep py 17560 pts/0 D 0:00 \_ grep py 17160 ?

Hi, It is said when using ASP it is not encouraged to use many session variables. Is this the same for Zope? Greets, Daniel

RE: [Zope] html space( ) in string

[Jos van der Vleuten ] > chr(38) is also rendered as & Too bad, I was hoping that the main problem was to get the ampersand through to the processor in a well-formed way. But it seems that the downstream escaping is too simple-minded. Cheers, Tom P

Need a product
by Patel, Tejash 25 Mar '03

25 Mar '03

Guys, I am looking for a product that does the following: After loaded: When you create that product it will create a folder not and item. When you view that product you have a option to upload other types of content on to it. ie: html, dtml, pt and so on. I guess it similar to the ZMI option of add a product from the drop down list, I need to create a customize version of it. I guess, any help out there. Thanks

Remeber to start zope with option: -W [portnumber] and connect with webdav this way: http://zopeserver.com:[portnumber]/folder and NOT the standard portnumber 8080 With Windows: I have only tried Dreamweaver, but it works fine (as long as you fiddle a littlte with something called "PUT_factory" (an external method which auto-creates the object-types you want)). also: Dreamweaver can not have filenames without ".html" or other filename endings (stupid, stupid, stupid). the locking-mechanism between dreamweaver and zope was not easy to figure out, put eventually, that also works ok (you have to remember to check in and out files). I'm going to test Golive the next couple of weeks. It may prove a better design-tool. BTW: use zope templates and not dtml-methods/documents. I have not, and I am starting to regret.

Communicating between ZEO master and client over SSL?
by Jean Jordaan 25 Mar '03

25 Mar '03

Hi all We want a ZOE master storage at one site, and a ZEO client at a remote site. We want to secure the connection between the client and the server. The best I could think up so far, is to set up an ssh tunnel between the two sites, forwarding a port on the local machine to one on the remote machine. But I'm sure there must be a best practice on how this should be done. Could someone point me at a HOWTO? I've found Pound, and Infrae's http://www.infrae.com/products/silva/docs/SysAdmin/SquidNotes but these look like they refer to a cluster of ZEO nodes at *one* site. -- Jean Jordaan http://www.upfrontsystems.co.za

RE: [Zope] Evaluating Output of Scripts as HTML in DTML Pages

You should not be using Python to write markup. You should have Python compute and return parameters to a DTML method which would then constrcut the form you want. This division of labor will work much better, and be easier to understand and maintain, than getting Python to write the markup directly (which certainly can be done, but is best not done). For example, the Python script could return a dictionary of values, which your DTML method would insert into your form template. Cheers, Tom P
