Einstieg in das CMS mit Zope
by Haas, Thomas 05 Nov '01

05 Nov '01

Hallo Zusammen, ich bin gerade dabei, mich um ein neues CMS für eine unserer Plattformen zu kümmern. Ist es für mich als "Nichthardcore-Programmierer" möglich, ein gutes CMS aufzusetzen? Wäre super, wenn ihr mir Feedback geben würdet. Es geht übrigens um das offizielle Oktoberfest-Web 2002, für das wir erst kürzlich den Auftrag bekommen haben. Es soll eine System sein, mit dem wir bzw. die User möglichst leicht und übersichtlich Beiträge verfassen können. Desweiteren ist ein Flirtforum geplant, vielleicht kann man ja beide Module unter einen Hut bringen und mit Zope aufsetzen. Danke für Eure Hilfe gruesse Tom Haas (technox.cc)

RE: [Zope] Zope Server Crashes

2 quick suggestions for some detective work: - watch your memory profile for Zope; determine if this is a problem (i.e. a leak in an app or Catalog, etc, use a tool like top) - enable "big M" logging... you can search the list archives for more info... Sean -----Original Message----- From: Michelle Jacobs [mailto:Michelle.Jacobs@ftech.net] Sent: Monday, November 05, 2001 8:01 AM To: zope(a)zope.org Subject: [Zope] Zope Server Crashes Hi, We've been running Zope on Linux since March 2001 and we've been quite pleased - even put our company web site on Zope. However, over the past few weeks we've experienced more and more frequent server crashes until finally, out of desperation, we upgraded from 2.3.2 to 2.4.2. The upgrade seemed to solve the problem temporarily, but we've been experiencing more and more crashes over the last few days. We've now installed a script which checks for failed requests and restarts Zope in the event of a crash, but the problem is only becoming worse. Server logs show only gaps and not much in the way of useful information while the server was down. Anyone out there have experience of this sort of thing with Zope or can offer any suggestions?

Zope & optimistic transactions.
by Clark OBrien 05 Nov '01

05 Nov '01

Chris, I set up a test harness to exercise zopes optimistic transaction management. My test immediatly caused a ZODB exception. I am running zope 2.42. on win 2k, the scripts are attached. Results below: As you recall I posed the following question: What if you had a directory structure like: Folder1 Folder-2 Folder-3 ... .. Folder-n Each folder had an attribute foo and there were two scripts, script1 and script2. script1 modified foo on one Folder only while script2 traversed all the folders modifying the attribute foo on each one of them. Would the script2 ever commit while the fist while script1 was continuously called. This is interesting because a call to script2 would never finish before several calls to script1 finished. I set up a simple test with only 10 folders. I then wrote the script below changeLevel2 that is my scri1 above and changeFolders that is my script2 above. I ran changeLevel2 in a loop using the following code: ----------------------------------------script------------------------------ ----------------- import urllib params = urllib.urlencode({'theText': 'Vitamin D'}) while 1: f = urllib.urlopen("http://localhost:8080/Test/changeLevel2?%s" % params) print f.read() -----------------------------------------script----------------------------- ------------------- I then ran the script changeFolders from my browsers. The result was the following error message: ------------------------------------------------------------ ZODB.POSException.ConflictError Sorry, a site error occurred. Traceback (innermost last): File C:\zope\lib\python\ZPublisher\Publish.py, line 223, in publish_module File C:\zope\lib\python\ZPublisher\Publish.py, line 200, in publish File C:\zope\lib\python\ZPublisher\Publish.py, line 200, in publish File C:\zope\lib\python\ZPublisher\Publish.py, line 200, in publish File C:\zope\lib\python\ZPublisher\Publish.py, line 195, in publish ---------------------------------------------------------- <<scripts.txt>>

Reading the xhtml 1.0 DTD again you are right - href is URI (CDATA) and should not be interpreted. So it seems that validator.w3.org is broken in this aspect? Look at this example, CDATA is set, but the ampersand is interpreted as start of an entity: 1: <!DOCTYPE html 2: PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" 3: "DTD/xhtml1-strict.dtd"> 4: <html> 5: <head> 6: <title>Test</title> 7: <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> 8: </head> 9: <body> 10: <p> 11: <a href="http://test.com/?a=b&b=c">Link 1</a> 12: <a href="http://test.com/?a=b&b=c">Link 2</a> 13: </p> 14: </body> 15: </html> Parse Tree Axmlns CDATA http://www.w3.org/1999/xhtml <html> <head> <title> Test </title> Ahttp-equiv CDATA Content-Type Acontent CDATA text/html; charset=iso-8859-1 <meta> </meta> </head> <body> <p> Ahref CDATA http://test.com/?a=b=c Ashape TOKEN rect <a> Link 1 </a> Ahref CDATA http://test.com/?a=b&b=c Ashape TOKEN rect <a> Link 2 </a> </p> </body> </html> Regards, Frank -- CTO Lightwerk GmbH Email: fte(a)Lightwerk.com Phone: +49 2434 800781 Fax: +49 2434 800794 An der Kull 11 * 41844 Wegberg * Germany

Please Help! Wierd error that wasn't there before...
by Rob Foster 05 Nov '01

05 Nov '01

I had this working before... a user fills out a form which posts to a script which in turn creates a new user. Now, when a user is created in acl_users and when I click on it, I get the error below... I've tried changing the roles, moving the acl_users directory and changing the python script, all to no avail. The Zope user stuff is becoming really frustrating. I could use some help.

Turn off Z2.log
by Tom Cameron 05 Nov '01

05 Nov '01

How do I turn off the Z2.log logging? I am running Zope behind apache and I am using apache for all the logging. I have turned on STUPID_LOGFILE, so I really have no need for the Z2.log file. It is just a waste of processing power and disk space. The flags for the Z2.py file show how to change the location of this file but not how to turn it off. Thanks Tom
