ImageFile in python class
by Jean-François Ménard 29 May '01

29 May '01

Thanks Marc for your response! But... There MUST be a better way to publish an image in a python class? Here is what I would like to do: class MyClass(self): """ Class example """ image = ImageFile('www/image.gif', globals()) index_html = DTMLFile('dtml/manage_myclass.dtml', globals()) def __init__(self, id, title): """ Initialization of my class """ ... How can I use the "image" property in my "index_html" dtml file??? I tried: <dtml-var image> give me a broken image. Then: <img src="<dtml-var absolute_url>/image> Broken image again... I looked at the code in OFS/misc_ , with no luck... Any help would be VERY appreciated... I'm stuck on this problem for _too_ long now... : / Thanks! J-F

CoreSessionTracking vs. SQLSession
by Joh Johannsen 29 May '01

29 May '01

For a brief period (a day), I had BOTH CoreSessionTracking and SQLSession maintaining session information. At random times, the CoreSessionTracking would totally lose ALL session data. SQLSession did not. This is CoreSessionTracking without any timeout set. My current understanding of this problem -- it does happen to others (not just me), but is very rare. The problem is not identified, is not reproducible by any digicool tests. I do have an environment which reproduces the problem within a short time, and would be glad to run any version of CoreSessionTracking that would help identify the problem. Currently I am running with SQLSession -- so far it has not had a single problem. Regards, JJ

Re: [Zope] the "cannot rename zclass" bug ...

Hi, is there any chance that the string in the management interface of your zclass, tab "Basic", field "Meta Type" is different from the "Add list Name" of your zclass's factory? If yes, correct that and I think it will work. Btw. does anybody know the exact meaning of these two zclass related properties? cheers, oliver

It works for me when I set the 'Parameters\start' key for the Zope service to the following value: "E:\PROGRA~1\ZOPE23~1\bin\python.exe" "E:\PROGRA~1\ZOPE23~1\z2.py" -S INSTANCE_HOME="e:\progra~1\ZopeHome" I don't recall if the quotes or 8.3 folder names are essential. -- Fred Yankowski fred(a)OntoSys.com tel: +1.630.879.1312 Principal Consultant www.OntoSys.com fax: +1.630.879.1370 OntoSys, Inc 38W242 Deerpath Rd, Batavia, IL 60510, USA

siteroot problem
by Wayne Izatt 29 May '01

29 May '01

I've used siteroot in the past, without any problems. With ProxyPass and ProxyPassReverse, I was able to run my beautiful zope nicely behind Apache. Then I upgraded to zope 2.3.2 It almost works, but not quite. Unfortunately, some weeks before upgrading Zope, I upgraded Apache, so I no longer have my old directives to look at. Here's how I set them up: <IfModule mod_proxy.c> ProxyRequests On ProxyPass /Zope/ http://127.0.0.1:8080/ ProxyPassReverse /Zope/ http://127.0.0.1:8080/ ProxyPass /misc_ http://127.0.0.1:8080/misc_ ProxyPass /p_ http://127.0.0.1:8080/p_ </IfModule> and my siteroot base looks like this: http://127.0.0.1:8080/Zope It almost works. When I go to http://127.0.0.1/Zope/ I get the welcome screen, minus the logo at the bottom. Clicking on the management link, however, takes me to the usual management frameset, but all three documents come up with notfound errors. Any ideas? ta Wayne _______________________________________________________ Do You Yahoo!? Get your free @yahoo.ca address at http://mail.yahoo.ca

IOError
by Sven Syld 29 May '01

29 May '01

Hello, My Zope has given me "IO error" last few days. Here's a fragment from traceback: /---/ File D:\PROGRA~1\Intra\lib\python\tempfile.py, line 110, in mktemp File D:\PROGRA~1\Intra\lib\python\tempfile.py, line 68, in gettempdir /end/ As the disk where temporary files are to be put was full I set environment variables TEMP=D:\TEMP and TMP=D:\TEMP . Gettempdir suggests that it uses these variables. But no use. Any help would be helpful Platform is NT 4.0, Zope version is 2.3.2. Sven

Migrating to Zope, Getting files in and out of Zope
by Pieter Biemond 29 May '01

29 May '01

Hello, I'm currently working on a project to migrate a fairly large intranet webserver (apache on linux) to a zope webserver (linux redhat 7.1). Because a lot of the applications/files on the old intranet are used on a daily basis I can't make the migration in one weekend So I need to setup a new server which I use to test all the applications one at the time, before the old server can be taken down. There are a number of problems I encounter: The nicest thing would be to temporary syndicate the old website through Zope and proxy the old server through the new server. Every request to http://newserver/somefile.html will be handled by the new server which retrieves http://oldserver/somefile.html and wraps it into a standard_html_header and standard_html_footer and extracts title and keywords correctly. Unfortuately, I didn't get this to work properly with the Python httplib. (see http://www.zope.org/Members/cba/Get_External and http://lists.zope.org/pipermail/zope/2001-February/126090.html) Did anybody manage to get something like this working? I am now working on the final migration and I will use a copy script every night to copy all the files from the Apache server to the new Zope server. During the nightly copy I want all the binary files (gif/jpg/PDF/Word/Powerpoint and even WordPerfect-files) to be written in a seperate repository (available to Zope through LocalFS or ExtFile objects, see http://www.zope.org/Members/sabaini/externalfiles-howto) Has anybody done this before? Pittfalls I should look out for? Should I use LocalFS or ExtFile? I tried copying all the files in a number of ways (ftp, load_site.py and webdav (using a windows client and using cadaver)) but all options seem to have problems with filenames that contain spaces (I know, you shouldn't use filenames with spaces, but people did). I'll still have to try the suckfs-command from the ZShell Product. Does anybody now a way to solve this problem? Another problem: I can't copy filenames starting with an underscore. Fortunately they don't need to be copied (they are used for Frontpage Extentions on the old server). Are there any other things I should take into account when using filenames in Zope? (length of filenames/directory names, number of files in a directory, special characters, etc.). I'm planning of writing a how-to of all the pittfals I encountered, and describing the best way and possibilities of migrating to a Zope site. Any help would be appreciated. Pieter

Hi, On winnt go to Control_Panel/Services/yourservice/startup/ and select a nt account to run the service with. Then in the odbc dsn if you choose to connect with a NT account the account you selected on the service will show in the profiler, if you choose a specific sql acount then that specific account should appear.

Zope NT Service and INSTANCE_HOME
by Francois-regis Chalaoux 29 May '01

29 May '01

Hi, The very good Howto at "http://www.zope.org/Members/4am/instancehome" describe a nice solution to start Zope with an another INSTANCE_HOME . However, this solution does not to be effective with the Zope NT service : If you create a INSTANCE_HOME with var, Extensions, import, Products, access entities, and you declare INSTANCE_HOME in start.bat, Zope find correctly your INSTANCE_HOME when you manually run start.bat. But if you start Zope as service it does not work even if you change the string INSTANCE_HOME in the NT register ? Is there a solution to affect an another INSTANCE_HOME to Zope service ? FR
