Dealing with international character sets
by Alexander Staubo 06 May '99

06 May '99

I note that Zope is converting strings with certain international characters into its own notation. Specifically, in my country our alphabet contains three additional characters. For example, "oslash" (\0xF8 on my system), which Zope expands into "\370". Oddly enough Zope does not have the same problem with other international characters such as accented letters, or the German alphabet. Now, this is extremely inconvenient when dealing with database tables, because obvious such things as name lookup won't work, and besides, any strings that are put into the table fields will use Zope syntax, not a "proper" character set (eg., ISO-8859-1, which is the one we use here). Is there a solution? For example, a function to convert the Zope string back to my kind of string? How can I get Zope to work with my international character set?

Corrupt Bobo Database?
by Tim Hawes 06 May '99

06 May '99

Zope was running fine until a couple days ago. It seemed to have locked up. I tried restarting pcgi, but got a SERIOUS APPLICATION ERROR when I tried to re-connect. This is what I found in the log file: Tue May 4 13:21:03 1999 unable to publish module Traceback (innermost last): File "/usr/local/https/Zope/pcgi/pcgi_publisher.py", line 301, in handler self.publish_module(self.moduleName,stdin=stdin,stdout=stdout,stderr=stderr,environ=env) File "/usr/local/https/Zope/lib/python/ZPublisher/Publish.py", line 878, in publish_module debug=debug) File "/usr/local/https/Zope/lib/python/ZPublisher/Publish.py", line 325, in publish (bobo_before, bobo_after, request_params, File "/usr/local/https/Zope/lib/python/ZPublisher/Publish.py", line 616, in get_module_info module=__import__(module_name, globals(), globals(), ('__doc__',)) File "/usr/local/https/Zope/lib/python/Main.py", line 103, in ?

Questions: 1) What might have caused this corruption? Two people logged in as admin (superuser) at the same time? Running a seperate instance of Zope (the latest CVS version) in another directory? 2) Can a corrupted bobobase file be fixed relatively easily (i.e. without an hex editor)? I am not fond of the idea of building an enterprise-wide web site with tens to hundreds developers working on the same site, and then see the whole thing get flushed down the toilet by the corruption of one file. Possible remedies might include creating a seperate database file for each division. But then how is acl security maintained throughout the site? Can one database use objects from another? Ideas, or answers? Tim Hawes tim.hawes(a)ncmail.net -- Tim Hawes tim.hawes(a)ncmail.net

If Zope does not find an object you ask for, it sends back a 404 not found response. I'm not sure where your welcome.htm file is coming from, but it's not from Zope. Check your httpd.conf. Maybe apache is configured to send out a document whena 404 is generated. -Michel > > Thanks for help. > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

I have some problems with migration from compiling languages as C++ to Python, and ZOPE programming techniques are difficult to understandable for me. Are exist some examples of working objects(in source text and comments as Poll)? Where?

Hello to all, We have probleme when we test a web site under linux Red hat 5.2 with Apache 1.3.3 and zope 1.10.2 If there is a link to an object which doesn't exist in the database of ZOPE, when we try to access this file with a browser, we do not have the message "file not found" but the server send a arbitrary page, welcome.htm with us ! Why ? What is the respond of ZOPE if he receive a request from APACHE to an objet (a html page) which doesn't exist in the database ? Thanks for help.

Zserver installation on Win95
by Tom Deprez 06 May '99

06 May '99

Hi, I've created a hosts file from the hosts.sam file.... so it exists. In there localhost is defined, including the other names of the PC's. So the error is there also when a hosts file is defined... :-((((((((((( snif. Tom. I believe that the problem is that medusa's ftp server wants to look up the hostname of the server machine. On Win95 machines which are not connected to a network this fails. I think that this can be fixed by adding an entry in your Win95 hosts file (\windows\hosts) like so: 127.0.0.1 localhost If I recall correctly, I think that a hosts file doesn't exist by default on Win95 machines. But there may be a sample hosts file in \windows\hosts.sam. That said, I think that medusa's ftp server shouldn't have to make this host name lookup. I am looking at implementing a fix/work around for this and submitting it to Sam Rushing. I'll also add this information to the ZServer INSTALL.txt file. -Amos
