Zope & MySQL on Win98

Hello Zope and MySQL users, I'm trying to access MySQL through Zope. I hope someone can point out my set-up error(s). Environment: Windows98: 4.10.98 MySQL Server: 3.23.21-beta-debug Zope v.: 2.2.0 (binary release, python 1.5.2, win32-x86) Python v.: 1.5.2 (#0, Jul 30 1999, 09:52:18) [MSC 32 bit (Intel)] ZMySQLDA v.: 1.1.4 (nonbinary) (in: <zope-dir>/lib/Products/ZMySQLDA/) MySQL.pyd 'MySQLmodule-1.4: A Python interface to the MySQL database.' (this from MySQL.__doc__) (in: <zope-dir>/bin/lib/) MySQL works fine through the mysqlc monitor and Python scripts using odi and odbc. But I keep crashing Zope/Python with even the simplest queries. Here's what I do, followed by the mysqld -log file entries. Start MySQL: C:\mysql\bin\mysqld.exe --console --log Start Zope: C:\Program Files\<zope-dir>\start.bat (Which is, out-of-the-box: "C:\Program Files\TotipotentZope\bin\python.exe" "C:\Program Files\TotipotentZope\z2.py" -D %1 %2 %3 %4 %5 %6 %7 %8 %9) Zope says: 2000-08-10T11:44:08 PROBLEM(100) ZServer Computing default hostname ------ 2000-08-10T11:44:08 INFO(0) ZServer Medusa (V1.16.4.2) started at Thu Aug 10 13:44:08 2000 Hostname: LAP_WILL Port:8080 (Other than PROBLEM(100), all looks fine.)

Getting rid of PTK
by Jean Jordaan 17 Aug '00

17 Aug '00

Hi list I've seen others having problems with this as well .. I made a ZClass, not consciously touching anything about PTK. Now when I export it ('ccDoc.zexp') and import it into another Zope, I get:: Error Type: ImportError Error Value: No module named PTKDemo.PersistentUserSource Traceback (innermost last): File C:\programs\ZopeJean\lib\python\ZPublisher\Publish.py, line 214, in publish_module File C:\programs\ZopeJean\lib\python\ZPublisher\Publish.py, line 179, in publish File C:\programs\ZopeJean\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File C:\programs\ZopeJean\lib\python\ZPublisher\Publish.py, line 165, in publish File C:\programs\ZopeJean\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_importObject) File C:\programs\ZopeJean\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: manage_importObject) File C:\programs\ZopeJean\lib\python\OFS\ObjectManager.py, line 488, in manage_importObject (Object: ElementWithAttributes) File C:\programs\ZopeJean\lib\python\OFS\ObjectManager.py, line 238, in _setObject (Object: ElementWithAttributes) File C:\programs\ZopeJean\lib\python\OFS\ObjectManager.py, line 254, in manage_afterAdd (Object: ElementWithAttributes) File C:\programs\ZopeJean\lib\python\ZClasses\ZClass.py, line 412, in manage_afterAdd (Object: ccDocClass) File C:\programs\ZopeJean\lib\python\ZClasses\ZClass.py, line 373, in _register (Object: ccDocClass) File C:\programs\ZopeJean\lib\python\ZODB\Connection.py, line 396, in setstate File C:\programs\ZopeJean\lib\python\ZODB\Connection.py, line 205, in _persistent_load (Info: What do I have to do with PTKDemo?? -- Jean Jordaan -- technical writer -- Mosaic Sofware -- Zope 2.1.6 on WinNT and W2K

Hi, When I create a ZClass instance from an external Method I create by default the instance in the same place where is located my external method (see the code below). How to select a different place in my script where will be create the ZClass ? ==== Code ==== def addZClass(self,id,data): newob=self.Control.Panel.Products.MyProduct.MyClass(id) newob.id=id newob.propertysheets.Properties.manage_changeProperties(data) self._setObject(id,newob) newob.reindex_object() Bye, FR.

RE: [Zope] Zope is very slow!

The speedup involves changing sys.checkinterval, which controls the interval (# of bytecodes) at which the Python runtime performs certain housekeeping chores. For multithreaded programs, upping this interval can cause a significant performance improvement (more about this on python.org in the sys module docs). 2.2 sets the interval to 120, a value that seemed to provide a general speedup across a number of systems I tested. Granted, this is not very scientific, which is why there is an '-i' option to z2.py that allows you to pass your own values for the interval to experiment and find a sweet spot for your given environment (see the z2.py docstring / command help). > >> else changed I didnt see?

Note that effective use of multiple processors is mostly a function of the Python runtime (specifically the global interpreter lock) rather than an issue that Zope can address directly. So yes, ZEO is the best way to make effective use of MP. Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

Announce: Squishdot 0.5.0 now available!
by Chris Withers 17 Aug '00

17 Aug '00

Squishdot 0.5.0 is now available from http://www.zope.org/Members/chrisw/Squishdot/ The following changes were made: - Support has been added for postings to be formatted as Plain Text, HTML or Structured text on the same site. - You can preview when editing postings through the management interface. A whole host of bugs were also fixed, the most notable being the one which caused the 'managemanage_editForm' bug. Sadly, Squishdot does not yet work with Zope 2.2 :( If you run into problems, remember Squishdot has a mailing list at eGroups and a bug collector on SourceForge. cheers, Chris

Product inhetitance question
by Daniel Rusch 17 Aug '00

17 Aug '00

Hey all, Say I have a fully functional (and more importantly, working) Product will call A. I want to extend this Product's capabilities so I wish to derive another class from it, call it B. No problem, class B(A): ......... The question is, (I think the answer is no) is there a way to inherit (i.e. reuse common code and extend it) the manage_Add function and the dtml files from A??? Thanks, DR

Zope and VirtualHost
by William JOYE 17 Aug '00

17 Aug '00

What's is the best way to host multiple virtual domain in Zope with Apache sever ? Actually, I use PCGI method with rewrite rules in Apache configuration like this : RewriteEngine on RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope/MySite/$1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] But I can't use BASE or URL variables because they always include 'MySite' folder. Is SiteAccess product can help me ?
