Form gets erased after 'View' and back button in ZMI
by Robin Smidsrod 11 Feb '02

11 Feb '02

This is best explained with an example. I edit a DTML Method. I press 'save changes'. ZMI says there is something wrong with the code, I press the 'back' button in my browser. IE then reports that the page is expired and I have to press refresh to get the contents of the form back. The edits I just made, which caused the error is gone and the form reverts to the last saved values for this document. I want to be able to see the cached page which includes the values I previously entered into the form (which had errors). This is probably some setting in Internet Explorer regarding caching and use of proxy, but I can't quite get the correct settings set. I've tried to add a Cache Manager object, but this has been removed again. I use IE 6.0.2600.0000.xpclient.010817-1148, WinXP Professional, squid-2.4.STABLE1-6. I don't think the proxy is wrong, because I experience the same behaviour when I turn it off in the browser. My IE cache settings is set to 'Check for newer versions of stored pages: Every visit to the page'. I've tried it on 'automatically', with and without proxy, but this doesn't help. I've tried the other options too, but it doesn't seem to do the trick. Am I missing something here? -- Robin PS: Mozilla 0.9.8 seems to do the right thing, so it's definitly a browser "problem".

Compile Python
by James Johnson 10 Feb '02

10 Feb '02

I'm using win 98 with dev c++ and the latest cygwin. I would like to use the gui of dev c++ but I've already tried to use cygwin to mount a temp directory to compile the zope source. I used something like "python wo_pcgi.py". I've looked at previous examples, I guess I'm not understanding the makefile/setup file part. Thanks, -James >I know this is Zope mailing list, but I would like to ask a Python >question. I am new in Zope and Python, but I would like to compile >Python myself in order to install Zope 2.5.0.

Xron problem, Data.fs disappeared!
by Marcin Rabiej 10 Feb '02

10 Feb '02

Hi, Here is what happened: I have Zope 2.4.1, Python 2.1, Xron-0-0-10 installed. I have three Xron Methods that run every 15 minutes and one that runs every day at 2 am (call it reportsender). At 2 am reportsender started and finished ok. Just after reportsender finished it's work, another Xronmethod was called - it finished with ok status. Than: 2002-02-09T02:00:03 ERROR(200) Catalog uncatalogObject unsuccessfully attempted to uncatalog an object with a uid of /TO/Reports/reportsender And reportsender started being called a few times every second. ....Until Data.fs has reached 2 Gb limit.... (it was at 02:51 am). From that time to about 11:36 am Zope was reporting errors reading Data.fs. At 11:36 it stopped reporting errors and started to work fine - nothing else suspicious happend. The only problem was that old data.fs disappeared and new one, empty appeared. I have here two problems: 1. How Xron could call reportsender million or more times? 2. How could my Data.fs had disappeared? The day before (08.02.2002) reportsender was moved (cut+paste) from one place to another. First it wasn't under any SiteRoot, after copying it came under SiteRoot and a UserFolder (i think it is the source of problem). 2002-02-09 01:00 - 13 GB free disk space Thank you for any suggestions why that happened

Greetings, I am getting a NameError when using Mozilla 0.9.x or Netscape 6. The application works fine using Internet Explorer.

Interesting - aren't the MySQL connections bound to a thread? YOu mean there may be a bug at a lower level than mysql-python?

httpd processes
by Stephan Goeldi 10 Feb '02

10 Feb '02

On one of our servers (RedHat 7.0) run about 15 productive Zope instances. Versions from 2.3.3 up to 2.5.0. We combine Apache with Zope. Sometimes, the number of httpd processes go up from about 9 processes to over 60 processes. All websites don't response then anymore. A simple httpd restart corrects this problem, and everything is fine again. Does anybody know of a Zope related issue which is responsible for such behaviour? _________________________________________________________________ Join the worlds largest e-mail service with MSN Hotmail. http://www.hotmail.com
