by Pascal Peregrina 13 Sep '05

Hi, Can somebody tell me what I should monkey patch if I need to alter Z2.log logging in order to append a particular request environment value ? I tried but I got lost trying to find PublisherHTTPServer and ZPublisher relationship... Thanks a lot.

MemoryError that brings my zope to its knees

In the last month I have started to get these errors using Zope 2.7.7 in a ZEO configuration with one client and one storage server: ------ 2005-09-12T23:46:07 ERROR(200) ZODB Couldn't load state for 0x055ba7 Traceback (most recent call last): File "/usr/local/Zope/lib/python/ZODB/Connection.py", line 600, in setstate self._set_ghost_state(obj, p) File "/usr/local/Zope/lib/python/ZODB/Connection.py", line 639, in _set_ghost_state state = unpickler.load() MemoryError ------ 2005-09-12T23:46:07 ERROR(200) SiteError Error while logging Traceback (most recent call last): File "/usr/local/Zope/lib/python/Products/SiteErrorLog/SiteErrorLog.py", line 142, in raising tb_text = ''.join( MemoryError Sometimes I see this too: ------ 2005-09-06T15:23:30 ERROR(200) ZServer uncaptured python exception, closing channel <select-trigger (pipe) at bd9104c> (exceptions.MemoryError: [/usr/local/lib/python2.3/asyncore.py|read|69] [/usr/local/lib/python2.3/asyncore.py|handle_read_event|390] [/usr/local/Zope/lib/python/ZServer/medusa/thread/select_trigger.py|handle_read|77] [/usr/local/lib/python2.3/asyncore.py|recv|342] [/usr/local/lib/python2.3/asyncore.py|recv|523]) And this one also brings the show down: ------ 2005-09-06T05:35:51 ERROR(200) zrpc:30832 can't decode message: "(M2'K\x00U\x06.reply(TW\x00\x01\x00((U\tOFS.Imageq\x01U..." ------ 2005-09-06T05:35:51 ERROR(200) zrpc-conn(C):localhost:6100 Error caught in asyncore Traceback (most recent call last): File "/usr/local/lib/python2.3/asyncore.py", line 69, in read obj.handle_read_event() File "/usr/local/lib/python2.3/asyncore.py", line 390, in handle_read_event self.handle_read() File "/usr/local/Zope/lib/python/ZEO/zrpc/smac.py", line 217, in handle_read self.message_input(msg) File "/usr/local/Zope/lib/python/ZEO/zrpc/connection.py", line 339, in message_input msgid, flags, name, args = self.marshal.decode(message) File "/usr/local/Zope/lib/python/ZEO/zrpc/marshal.py", line 39, in decode return unpickler.load() # msgid, flags, name, args MemoryError It completely locks up the zope until I restart. I added more RAM to the box and also bumped up the zeo cache-size to 100MB and 10000 objects in the zope.conf. I also changed over from binding to an external ethernet interface and bound the zeo stuff to the localhost interface. Any ideas on other things I could try?

Virtual Host Monster
by Nicholas Wieland 12 Sep '05

12 Sep '05

I'm trying to use VHM to rewrite a pair of urls. What I want is to have a "normal" Zope on localhost:8080/, and an instance of a Product on localhost:8080/myProduct. The problem I'm having is that VHM locks me out from the root folder :( My mappings line is: localhost:8080/my_container/VirtualHostRoot/myProduct How do I exclude localhost:8080 to behave normally, as without Virtual Host Monster ? --------------------------------- Yahoo!

Copying "Data.fs" to a different CPU architecture
by Matthew X. Economou 12 Sep '05

12 Sep '05

My Zope server is currently an Alpha running FreeBSD. This computer's CPU is no longer working. I would like to restore my backup copy of Data.fs to a new computer, a PC running FreeBSD. Will this work as a straightforward copy, or will the two platform's differing byte orders (and word sizes) cause problems for me? Best wishes, Matthew -- jsoffron: I'm generally pretty high on national defense... Mr. Bad Example: Careful...it's a gateway policy. Before you know it, you'll be mainlining the hard stuff like trade agreements. jsoffron: Too late...I've been freebasing Nafta all day... Sweet, sweet NAFTA. - As seen on Slashdot

CMFFSContent released
by Jens Vagelpohl 10 Sep '05

10 Sep '05

CMFFSContent - Put CMF content onto the file system If you are looking for a way to manage content on the file system in order to take advantage of better editors, source control systems and other utilities you might be interested in CMFFSContent. CMFFSContent represents a content-ish equivalent to the CMF Skins mechanism. You can register directories that provide filesystem content and file extensions that should be recognized as one of the content types available (FSFile, FSImage, FSDocument) from your code. You can also derive your own FS-based content types and plug them into the machinery. A specific use case would be a "brochure" site that does not offer membership or member-contributed content, but a seldom-changing set of pages that need to be tightly controlled. Case in point: My company page at http://www.zetwork.com, which serves CMFFSContent only. Another suitable candidate would be a site that does have members and member-contributed content, but a specific area for centrally-maintained information, such as a canonical set of documentation pages. Downloads can be found at... http://www.dataflake.org/software/cmffscontent/ ...and bug reports/suggestions/praise/flames are welcome here: http://www.dataflake.org/tracker/ jens

by Martin Koekenberg 10 Sep '05

Hello, A while ago I used the products 'Superlogger' and 'Quicklinks.' I Also removed 'PlacelessTranslationService'. All the products were available in the control_panel. But I still get the following warnings ? 2005-09-10 16:49:05 WARNING ZODB Could not import class 'PlacelessTranslationService' from module 'Products.PlacelessTranslationService.PlacelessTranslationService' 2005-09-10 16:49:05 WARNING ZODB Could not import class 'SuperLogger' from module 'Products.SuperLogger.SuperLogger' 2005-09-10 16:49:05 WARNING ZODB Could not import class 'QuickLinks' from module 'Products.QuickLinks.QuickLinks' Does anybody has a solutiuon for this ? Zope is still running..... but the warning isn't there without a reason. regards, Martin Koekenberg

Testing arguments in zsql methods
by Pablo Ziliani 09 Sep '05

09 Sep '05

Hi everyone, I have what I think is a banal question here... Is there any way I can test inside a zsql method if an argument has been passed? <dtml-if foo> won't work because 0 (zero) is an expected value. Have tried <dtml-if "_.hasattr(_, 'foo')"> but it seems to be always false (where's that namespace?) TIA, Pablo
