Getting Zope root object without object context.
by Gilles Lenfant 06 Nov '02

Hi, I know I can get the root object using self.getPhysicalRoot() But I'm in a situation where I can't get that "self" or any other Zope object. Any hint ? Thanks in advance. --Gilles

Re: [ZODB-Dev] Recovering Corrupt Database part2

Hello zope-dev, as a suggestion from another mailing list user i have forwarded my current problem to this list. To summarize it seems that due to some hard drive corruption my zopedb has been left open with a lot of open transactions. When i try to clean the db with fsrecover i get numerous version lock errors and the db wont load. I have included my email to ZobDB-dev as a more thorought explanation. --tomasz On Mon, 4 Nov 2002, Jeremy Hylton wrote: > >>>>> "TZ" == tomasz <tomasz(a)pucky.ods.org> writes: > > TZ> This is a follow up email that was sent out a week ago by my > TZ> partner Cody Smith. it can be found at. > > TZ> http://lists.zope.org/pipermail/zodb-dev/2002-October/003476.html > > TZ> After multiple suggestions to upgrade to Zope-2.6 from > TZ> Zope-2.3.2 we did so.

Using Zope from a console script
by Gilles Lenfant 05 Nov '02

05 Nov '02

I tried (successfully) to play with Zope objects with console scripts using the hints in $ZOPEROOT/doc/ZODB.txt Unfortunately, it works only if the Zope server is down. I need to run this script on a running server, and I'd prefer not using xmlrpc stuffs for a better efficiency. Any hint, config, examples ? Thanks in advance --Gilles

Using restricted code from within a python product
by Brent Hendricks 05 Nov '02

05 Nov '02

I have a method in a python Product that I'd like to have run as restricted code. Is there an easy way to do this? I was hoping for a PythonScriptFile() along the lines of PageTemplateFile(), but such a thing doesn't seem to exist. Thanks -- Brent ------------------------------------------------------------------------- "The programmer, like the poet, works only slightly removed from pure thought-stuff.

strange overflowerror "long int too large to convert"
by Tobias Herp 05 Nov '02

05 Nov '02

Hi, we have a Zope-based (v2.5.0) editorial system running on a server of our customer's; it uses a ZUserFolder to store eMail addresses of the top-level users. Last week, an error turned up whenever the system tried to automatically send a notification eMail, which said: Error Type: OverflowError Error Value: long int too large to convert Poking around, I found that the error occurred as well when I tried to view the ZUserFolder instance in the root directory. Here is the traceback: >> Traceback (innermost last): File /data/opt/Zope-2.5.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /data/opt/Zope-2.5.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 114, in publish File /data/opt/Zope-2.5.0-linux2-x86/lib/python/Zope/__init__.py, line 158, in zpublisher_exception_hook (Object: acl_users_contact) File /data/opt/Zope-2.5.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 98, in publish File /data/opt/Zope-2.5.0-linux2-x86/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: manage_main) File /data/opt/Zope-2.5.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: manage_main) File /data/opt/Zope-2.5.0-linux2-x86/lib/python/Shared/DC/Scripts/Bindings.py, line 252, in __call__ (Object: manage_main) File /data/opt/Zope-2.5.0-linux2-x86/lib/python/Shared/DC/Scripts/Bindings.py, line 283, in _bindAndExec (Object: manage_main) File /data/opt/Zope-2.5.0-linux2-x86/lib/python/App/special_dtml.py, line 172, in _exec (Object: manage_main) File /data/opt/Zope-2.5.0-linux2-x86/lib/python/DocumentTemplate/DT_In.py, line 637, in renderwob (Object: objectItems) File /data/opt/Zope-2.5.0-linux2-x86/lib/python/DocumentTemplate/DT_In.py, line 763, in sort_sequence (Object: objectItems) File /data/opt/Zope-2.5.0-linux2-x86/lib/python/ZODB/Connection.py, line 446, in setstate File /data/opt/Zope-2.5.0-linux2-x86/lib/python/ZODB/FileStorage.py, line 559, in load (Object: /opt/zope/var/Data.fs) File /data/opt/Zope-2.5.0-linux2-x86/lib/python/ZODB/FileStorage.py, line 547, in _load (Object: /opt/zope/var/Data.fs) File /data/opt/Zope-2.5.0-linux2-x86/lib/python/ZODB/FileStorage.py, line 1902, in _loadBack OverflowError: (see above) << (Zope 2.5.0 (binary release, python 2.1, linux2-x86), python 2.1.2, linux2) Since I can't find any relation to something we did: 1. Is this error known to anyone, possibly related to a known bug of Zope 2.5.0? 2. Is it possible that the usage of ZClasses is the reason for the problem, and that ZClasses tend to go berserk after a while? (our product contains nested ZClasses, which is not how we'd do it today, but how we did it... the user class used by ZUserFolder is not a nested one, though) 3. Can anyone give me a hint where to search for the bug? I'd happily provide additional info, if requested. As a workaround, we disabled the automagic email feature, but this is not the ultimate solution.

Unicode Support in 2.6 -- background infos?
by Joachim Werner 05 Nov '02

05 Nov '02

Hi! I am currently fighting with the unicode support in Zope 2.6. Actually the problem is that I don't want to get pages delivered as unicode. Is the exact behavior of that thingie documented somewhere? Or could someone please give me a hint on how it works? The actual case is that I have a formulator form that sometimes is displayed correctly (that is with the good old Western ISO encoding) and sometimes in Unicode UTF-8. Which then results in broken German umlauts ... I know that I can force Unicode mode by having some unicode string on the page. But can I also do the reverse?

Hi, Abel, (sticking to english after Rüffel in another forum ..;-) thanks for answering. Unfortunately, it's not the data.fs size :-|. The database was about 400 MB in size, after packing 140 MB, and the problem still there.

acessing raw header information?
by holger krekel 03 Nov '02

03 Nov '02

Hello, After digging some time in the zope sources i couldn't find a way to access the 'Authorization' Request-Header inside a PythonScript or PageTemplate. I need this to circumvent a javascript/Mozilla bug. Is there a way to access 'Authorization' Header or raw request headers in general? don't have to much experience with zope-mailing lists culture so hopefully this is not the wrong list... thanks, holger

Web Services for Zope; what happened?
by Stefan H. Holek 01 Nov '02

01 Nov '02

I'd like to know what happened to this proposal: <http://www.zope.org/Wikis/DevSite/Projects/WebServicesForZope/FrontPage> Is the WebServices package (CVS) working? Any technical reason why it was discontinued? Thanks, Stefan -- Those who write software only for pay should go hurt some other field. /Erik Naggum/
