[Zope] ZopeProfiler issue

[Pascal Peregrina]

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

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.

Pascal
