Re: [Zope-dev] Trapping Interbase Error Codes

It also provides methods on getting the sql error number, message and message list. Like if my sql query would cause and -803 error, then gvib would return an IntegrityError. But aside from knowing the sql error code, what i really want is to get/trap the Interbase status array codes (isc_deadlock), well if that is possible. And is it only by using External Python scripts that i can do all these error handling, plus the rollback/commit of Zope/database transactions? Any help would be greatly appreciated. __ Do You Yahoo!? Try FREE Yahoo!

Could you use tcpwatch (or another TCP logger) to see whether the Zope response contains the cookie header. If not, this would be a Zope problem we could debug. If so, we have to look elsewhere. Here is the information. 5 cases are shown - Use of Apache + RewriteRule + VHM (CMF auth. cookie is __ac_erp5) - Use of Apache + RewriteRule + VHM (CMF auth. cookie is __ac) - Use of Medusa (CMF auth. cookie is __ac) - Use of Apache + RewriteRule w/o VHM (CMF auth. cookie is __ac_erp5) - Use of Apache + RewriteRule w/o VHM (CMF auth. cookie is __ac) The scenario is - go to http://www.erp5.org/login_form - look at what happens with tcpdump after filing the form and posting it In all cases, this leads to a login success. However, if the auth. cookie is not set (which happens in cases where Apache is used and aut. cookie is __ac), then we are in trouble... You will see that the Set-Cookie is different in the 5 cases My conclusion for now is that something could be wrong with the Apache rewriting process. Regards, JPS.

Re: [Zope-dev] Manual object-to-relational persistency framework
Thanks Dieter, I think ZPatterns is certainly worth a look. It allows you to slice-and-dice what you want to store in ZODB or RDBMS. The best part is you can develop totally in ZODB, then migrate to RDB a bit at a time (if you like) without changing your app, or your data classes. We have multiple instance of the same app mixing up ZODB, RDB, LDAP etc.. since all the wiring of data-objects is done in configurable data managers on an instance by instance basis. http://www.zope.org/Members/pje/ZPatterns for Zope-2.[45].x see also: http://www.cat-box.net/steve/TransactionAgents Three chapters of our book (www.zopeonarope.com) are devoted to implementing ZPatterns based apps. good luck! -steve On Friday, March 8, 2002, at 02:56 PM, Dieter Maurer wrote: Bjorn Stabell writes: I'm trying to use Zope without storing everything in ZODB while still having the perception of an object-oriented database.

Re: SV: [Zope-dev] Small Alert - Probably Apache / mod-rewrite
Hi,
I did a few more tests. Apparently, this cookie issue
- happens in proxy mode
- does not happen in CGI mode
Of course, it is required to delete all cookies stored in the browser once
the __ac cookie has been successfully set in CGI mode
I have enclose an excerpt of my Apache config which shows various tests.

Re: [Zope-dev] Unauthorized users can writelock helpfiles in /Control_Panel/Products
There is no way to fix this? What other problems are there with the help system? Not that I can think of. Other problems with the help system are presentation, mostly. Would it somehow be possible to make the helpsystem ignore versions? No, unfortunately. It uses the Catalog, which is based on ZODB, and it puts a Catalog instance into the main FileStorage, which is undoing and versioning. It then proceeds to do writes to the database when it appears that all you're doing is reading a pre-existing page. If you're in a version at the time, a set of objects will be written into the Catalog and into other places in instance space that have version. This is a bad pattern, and the only way to fix it is to prevent it from happening, which requires some helpsystem architectural changes that amount (IMHO) to a rewrite. - C -- Chris McDonoughZope Corporation http://www.zope.org http://www.zope.com Killing hundreds of birds with thousands of stones ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

When I read the dumps correct then *ALL* Apache + __ac dumps lack the __ac cookie whether or nor VHM is used. Thus, I would say, VHM is out of suspicion. Now, Apache + Zope via mod_proxy is Zope via Medusa. I do not expect Zope to behave differently when Apache is there.
