ftp server deadlocking zope with DeadlockDebugger
by Michael Kaplan 08 May '06

08 May '06

Hello, about 2 weeks ago I reported about my ftp-problem (see attached listing). In the meantime I installed DeadlockDebugger-1.0.tgz from http://www.zope.org/Members/nuxeo/Products/DeadlockDebugger Here is the output of this program for the thread that seems to be responsible for the deadlock. This happens when I open a ftp connection to the server, cd to a directory and launch the 'ls'-command: Thread 11 (GET /dirname/manage_FTPlist): File "/usr/local/mypackages/Zope-2.8.5-final/lib/python/ZServer/PubCore/ZServerPublisher.py", line 23, in __init__ response=response) File "/usr/local/mypackages/Zope-2.8.5-final/lib/python/ZPublisher/Publish.py", line 386, in publish_module environ, debug, request, response) File "/usr/local/mypackages/Zope-2.8.5-final/lib/python/ZPublisher/Publish.py", line 187, in publish_module_standard response = publish(request, module_name, after_list, debug=debug) File "/home/www/Zope-2.8.5-0/Products/PlacelessTranslationService/PatchStringIO.py", line 51, in new_publish x = Publish.old_publish(request, module_name, after_list, debug) File "/usr/local/mypackages/Zope-2.8.5-final/lib/python/ZPublisher/Publish.py", line 104, in publish object=request.traverse(path, validated_hook=validated_hook) File "/usr/local/mypackages/Zope-2.8.5-final/lib/python/ZPublisher/BaseRequest.py", line 272, in traverse bpth(object, self) File "/home/www/Zope-2.8.5-0/Products/LinguaPlone/I18NBaseObject.py", line 421, in __before_publishing_traverse__ stack.append('not_available_lang') File "/home/www/Zope-2.8.5-0/Products/LinguaPlone/I18NBaseObject.py", line 140, in getTranslation return l and l[0] or l File "/home/www/Zope-2.8.5-0/Products/LinguaPlone/I18NBaseObject.py", line 176, in getTranslations return self.getCanonical().getTranslations() File "/home/www/Zope-2.8.5-0/Products/LinguaPlone/I18NBaseObject.py", line 232, in getCanonical return ret File "/home/www/Zope-2.8.5-0/Products/LinguaPlone/I18NBaseObject.py", line 196, in isCanonical return not bool(self.getReferenceImpl(config.RELATIONSHIP)) File "/home/www/Zope-2.8.5-0/Products/Archetypes/Referenceable.py", line 105, in getReferenceImpl return refs File "/home/www/Zope-2.8.5-0/Products/Archetypes/ReferenceEngine.py", line 583, in getReferences return self._resolveBrains(brains) File "/home/www/Zope-2.8.5-0/Products/Archetypes/ReferenceEngine.py", line 716, in _uidFor return uuid, obj File "/home/www/Zope-2.8.5-0/Products/Archetypes/ReferenceEngine.py", line 634, in isReferenceable return (IReferenceable.isImplementedBy(object) or File "/usr/local/mypackages/Zope-2.8.5-final/lib/python/Interface/_InterfaceClass.py", line 111, in isImplementedBy return visitImplements( File "/usr/local/mypackages/Zope-2.8.5-final/lib/python/Interface/Implements.py", line 86, in visitImplements return r File "/usr/local/mypackages/Zope-2.8.5-final/lib/python/Interface/Implements.py", line 86, in visitImplements return r File "/usr/local/mypackages/Zope-2.8.5-final/lib/python/Interface/Implements.py", line 86, in visitImplements return r File "/usr/local/mypackages/Zope-2.8.5-final/lib/python/Interface/Implements.py", line 81, in visitImplements elif implements_class == TupleType or type(implements) is TupleType: Could anybody explain what's wrong here and how to repair it?

Re: [Zope] Questions on ZODB BTrees versus bsddb BTrees

Hi Chris Yesterday you said: Chris> Not everything is as hard as some people manage to make it ;-) And today this | >> | $ cd Zope-2.0.0a3-src/ | Chris> And what version of Zope are we on now? and | Chris> But really, with Open Source, it's up to you to be the judge. If a That's 3 times where I somehow get to be in the wrong for taking the time to point out that a piece of documentation in the project is quite misleading. I do well understand that the principle of caveat emptor applies to open source. But, many people have worked for a long time on zope and they've spent so much time in packaging it up and making it available because they also want it to be used by others. That's one of the aims. It works against that aim if the documentation is misleading. And, it works against the aim of having more people involved if someone new and well-intentioned shows up, runs into what looks like a clear (and, yes, very minor) problem, takes the time to report it, and is then repeatedly told that they're in the wrong! | Chris> Well, by all means report this anachronism to zope-web(a)zope.org, and | Chris> someone will hopefully delete it. Ok, will do. | Chris> If a document is over 3 years old and mentions a version of Zope | Chris> that's *nine* point releases earlier than the one you're using, d'ya | Chris> not think it might be out of date? ;-) Sure. But when it's the only thing you have to go on, when the document is sitting on the official zope.org web site, and when it says something is separately downloadable, experience dictates that you ignore the mentioned version number and go looking for the latest version of that thing. Which is exactly what I did. BTW, I don't personally mind your reaction at all (and I did see the original smiley). I was trying to help yesterday. I'm trying to now too, when I say that I don't think it's in the best interests of the project to tell newcomers who run across problems that they're in the wrong because they were naive enough to read and rely on the documentation. Anyway, no hard feelings, and thank for your replies. Apologies for so many words. Regards, Terry

psycopgda
by Josh Stephenson 08 May '06

08 May '06

I recently installed psycopgda version 1.0.0 and restarted zope. I can see that it installed because it's listed under products in zope's control panel, but it's not listed in the drop-down menu where all the other products are. I installed by doing: python install.py build python install.py install Zope 2.9.2 Python 2.4.2 PostgreSQL 8.1.3 I've tried installing psycopg version 2-2.0b8, but I don't even get a listing in the products under zope's control panel. What am I doing wrong?

First run TypeError
by David Pratt 08 May '06

08 May '06

Hi. I have been experimenting with making a hybrid storage for zodb. The storage seems to work well except that I am getting this error on the first request to the server and I am not exactly sure where it is coming from. Error Type: TypeError Error Value: unbound method method_descriptor object must be called with Application instance as first argument (got RequestContainer instance instead) When I refresh the browser, I get my login and no problems at all using the zope instance etc. The event and error logs are clean. But when I restart the server, the error appears on startup again. Many thanks. Regards, David

converting bytestreams from iso-8859-1 to utf-8
by Giuseppe Bonelli 06 May '06

06 May '06

Hi all, sorry if this is not zope specific, but can someone please explain to me the following behaviour when trying to convert an iso-8859-1 string read from a file to an utf-8 encoded one? s='\x93test\x94' #an iso-8859-1 string #\x93 and \x94 are left and right #double quotation marks, #as seen in a browser set to iso-8859-1 ss=unicode(s,'iso-8859-1').encode('utf-8') gives ss='\xc2\x93test\xc2\x94' which is wrong (as seen in a browser set to utf-8)! but: u=unicode(s,'iso-8859-1') u=u.replace(u'\x93',u'\u201C') #u201C is unicode left double quot mark u=u.replace(u'\x94',u'\u201D') #u201d is unicode right double quot mark ss=u.encode('utf-8') gives ss='\xe2\x80\x9ctest\xe2\x80\x9d' which is right (as seen in a browser set to utf-8)! Do I have to explicitly replace all characters above \x7F ? TIA __peppo

problem opening pdf-files with firefox in LocalFS folders on Zope
by Marinussen, M.J. (Ria) 05 May '06

05 May '06

Hi, I've got Zope 2.8.5 installed with LocalFS version LocalFS-1-3-andreas on Solaris (SunOs 5.8, I'm not sure which version number of solaris that is...) When I place pdf-files in the LocalFS directories, sometimes they open correctly, but most of the time they open as text-file when using Firefox. With other browsers (Internet Explorer, Opera) this problem does not occur. In the directory-listing the files are all identified correctly as type "application/pdf". At first I thought that Firefox had problems with some documentversions of pdf, so instead of using version 1.6 I tried 1.2. But no luck. When placing the files in the zope db, and not in a LocalFS folder, Firefox has no problems with any of them, and just opens them fine. Does anyone have a clue what is going wrong here and even better, how I can solve this problem? Thanks in advance, Ria Marinussen
