ANN: MailManager 2.0 rc2 & news from us
by Andrew Veitch 27 Jun '05

27 Jun '05

To keep traffic down I don't announce every MailManager release but 2.0 is a milestone for us. This is still very much a Zope product but with 2.0 we're now storing the mail in PostgreSQL (and shortly other RDBMs too) rather than the ZODB. We are still fans of the ZODB but for our particular use case (multi terabyte storage requirement and very heavy amounts of writing) we found that PostgreSQL performed better. We have now migrated our commercial customers to the 2.0 architecture so we are pretty happy with it. Our other news is that we received a small venture capital investment in the company last week. It's just a bit over $0.5 million and we're going to use it to work through the feature suggestions we've had. I would like to thank everyone who's helped us develop MM from going to the bother of submitting a bug report or suggesting a feature or doing a translation. There's more info about our company news here if you are interested: http://www.theregister.co.uk/2005/06/23/logicalware_vc/ http://scotlandonsunday.scotsman.com/business.cfm?id=702472005 The final bit of news is that we've changed the name of the company from Logical Progression to Logicalware. It's a bit shorter and easier to type! Best regards Andrew -- Logicalware Ltd Stuart House, Eskmills, Station Road, Musselburgh EH21 7PQ, UK Tel +44 (0)131 273 5130 Web: http://www.logicalware.com/

RE: [Zope] Sharing global data between threads / locking a method

Curious, - to save variables in this way, must a Folder property be used, or would a class variable set on something that extends Folder work the same? - why does temp_folder perform faster for this technique?

ZopeProfiler issue
by Pascal Peregrina 27 Jun '05

27 Jun '05

Hi, In a previous mail, I was asking if anyone had issues with ZopeProfiler and Zope 2.8. I have made many more tests and my issue is completely unrelated with Zope 2.8 (I got the same issue with Zope 2.7.6) The issue has to deal with an XML-RPC call to a java service (using the standard xmlrpclib module). The code is (method of a class of my own): def query(self): from xmlrpclib import ServerProxy, loads, ProtocolError try: if self.protocol=='HTTP GET': self.result=loads(urlopen(self.url).read())[0][0] elif self.protocol=='XMLRPC': self.result=getattr(ServerProxy(self.url),self.rpc_method_expr)(*self.params ) except ProtocolError: self.result=None self.zeroconf_exception=1 self.log_exception() except SocketError: self.result=None self.zeroconf_exception=1 self.log_exception() except IOError: self.result=None self.zeroconf_exception=1 self.log_exception() except: self.result=None self.log_exception() This works fine with disabled profiler. However, when I enable the profiler, I get this error : Fault: <Fault 0: 'java.lang.Exception: RPC handler object "cat.getProducts" not found and no default handler registered\n\tat org.apache.xmlrpc.SelfDocumentingHandlerMapping.getHandler(Ljava.lang.String ;)Ljava.lang.Object;(Unknown Source)\n\tat org.apache.xmlrpc.XmlRpcWorker.execute(Ljava.io.InputStream;Lorg.apache.xmlr pc.XmlRpcContext;)[B(XmlRpcWorker.java:183)\n\tat org.apache.xmlrpc.DocXmlRpcServer.execute(Ljava.io.InputStream;Lorg.apache.x mlrpc.XmlRpcContext;)[B(Unknown Source)\n\tat org.apache.xmlrpc.DocXmlRpcServer.execute(Ljava.io.InputStream;Ljava.lang.St ring;Ljava.lang.String;)[B(Unknown Source)\n\tat org.apache.xmlrpc.DocXmlRpcWebServer$Connection.run()V(Unknown Source)\n\tat org.apache.xmlrpc.DocXmlRpcWebServer$Runner.run()V(Unknown Source)\n\tat java.lang.Thread.run()V(Optimized Method)\n\tat java.lang.Thread.startThreadFromVM(Ljava.lang.Thread;)V(Optimized Method)\n'> I can reproduce that error if I omit (*self.params) on that line : self.result=getattr(ServerProxy(self.url),self.rpc_method_expr)(*self.params ) But when I add some logging, self.params looks fine. Changing that line into : self.result=apply(getattr(ServerProxy(self.url),self.rpc_method_expr),self.p arams) Gives the same error. I also tried hardcoding the arguments, and I still get the same issue ! I don't know what to do, I really need to profile my Zope instance. So any suggestion would be highly appreciated... Thanks.

problems with testing (PloneMailBoxer)
by robert rottermann 25 Jun '05

25 Jun '05

Hi there, I have a problem testing PloneMailBoxer I am using the Method added at the end getter = self.getProperty('getter') getterHandler = self.unrestrictedTraverse(getter, default=None) Calling the method in a test case I allways get None. In a real Plone setup it works fine. can somebody tell me why that is so? (Or where to look for a solution) thanks Robert security.declareProtected('Access contents information', 'getValueFor') def getValueFor(self, key): # Returns value for property; # if available, a dynamic getter will be used # we can not use MailBoxers getValueFor since # it does not work with skin elements on the FS getter = self.getProperty('getter') if getter: getterHandler = self.unrestrictedTraverse(getter, default=None) if getterHandler is not None: try: result = getterHandler(key) if result is not None: return result except: pass # Our stored properties are the default return self.getProperty(key)

Why the hell hasn't Page Templates taken over the world?
by John Poltorak 24 Jun '05

24 Jun '05

I found the question posed on the subject line whilst searching for information about ZPT's on a website called ZopeZen which appears now to have expired - I only found the reference in Google's cache. The question was posed about a year ago and seemed to be correctly answered by this post:- documentation maybe? Posted by nan at 2004-08-06 03:08 PM tal / metal / tales has a steep learning curve and the documentation is not that good at all ( I think on a printout it is 4 - 6 pages) E.g. the tal:on-error (which is extremly usefull) gets only one tiny paragraph. I think if it had a more comprehensive documentation (with LOTs of examples) it would not scare of new users that much as it does right now. It seems that I'm not the only one who woul like to see more examples of ZPTs. Is there a repository for examples of what you can do with ZPT's to make a web page look nicely set out? -- John

I'm attempting to convert a page which uses DTML into one which uses ZPT but can't get it to look the same. Can some kind person quickly check over my poor attempt to utilise ZPT to see what I've done wrong? -- John

Re: [Zope] From Zope 2.5.1 to Zope 2.7.6
by Tim Suter 24 Jun '05

24 Jun '05

Yep, I think I hosed the new install. I imported the old Data.fs and corresponding .zexp files over and now it won't let me into the localhost:8080/manage interface even. I keep getting connection refused messages there. I have restarted zope. Tried to restore the working Data.fs file...but all is still not well. When I point to the Start Page that everyone should see, I get the authentication window and it does authenticate, but then I get "Bad Gateway The proxy server received an invalid response from an upstream server." Do I have to start all over? Which is ok and maybe more efficient in getting this project off my plate (rather then peck my way through code I have no understanding of, (python). Unless you know what I can do to fix it quickly. Is there a way to cleanly uninstall Zope if I have to go this route? I compiled from the tar.gz and didn't use an RPM. Then what I want to do is start all over and set up a knowledge base: On an RHEL4 box: A fresh install of Zope (2.8.0 now) with; an apache2 front end with rewrite and redirect turned on so I can authenticate via LDAP, use our internal MySQL instead of the Zope DB, I want anyone to be able to edit freely provided they have the right authentication credentials from our organization, then import all the old knowledge base data from the Zope 2.5.1 install on the other Debian box to use in the new fresh install of Zope on the new RHEL4 install. Can anyone provide me some notes if you have similar installs and what I need to do to get this up and running? I have many projects going on right now, this one, is just the tip of the iceberg of Open Source technology that I am trying to absorb. Please don't tell me to RTFM because I am doing that already. My head is literally spinning with Perl, Python, LDAP, Apache, Zope, Linux, Unix, OpenBSD....Don't get me wrong, I love it. I just need to make some progress on this through a good HowTO whether its already documented and I have overlooked it or if any of you would like to spend some time to help a very receptive learner.
