Re: [Zope] XML-RPC within ZOPE
Jan-Ole Esleben wrote at 2005-12-11 19:10 +0100: Is it at all impossible to use XML-RPC _within_ a ZOPE architecture? In principle yes. Be careful however: it is easy to introduce deadlocks! When during request processing you call back into the same Zope via XML-RPC, the calling out request will not complete until the XML-RPC returns a result (this always holds for calls, XML-RPC or other, to an external or internal server). Zope has a limited amount of workers (the default is 4) able to execute requests. If there are no free workers, requests have to wait for one. Now imagine that as many requests arrive as there are workers and each of them wants to perform an XML-RPC against the same Zope. Then you have a deadlock: none of the XML-RPC requests will finish, because there are no free workers. An no worker will ever become free again, because each of them waits for its XML-RPC to finish. Therefore, you should directly call internal resources (rather than use XML-RPC). -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] XML-RPC within ZOPE
The problem is that it isn't my design, and the design is part of a contract. I can't really do anything about that (the major problem is that there will be SOAP components that might even need to be transparently integrated - which completely excludes ZEO). I tried doing my own commits, but it doesn't work, it just bombs earlier (no matter where I do them). I really don't know why, my only guess is that something about the transaction management breaks terribly when you go back and forth between objects without them being able to track it.

Re: [ZOPE] XML-RPC within ZOPE
Chris: the errors I get are always ConflictErrors without any usable tracebacks. I would like to give more information, but it really is very complex when you go a little deeper and would probably not be useful. I'll try to describe it a little better anyway: I have an Object that offers an interface for dispatching methods. It does so by deciding wether the method's object is on the local server or not, and depending on that, calls it via XML-RPC or via the ZOPE context (self). A remote ZOPE server cannot be part of a ZEO backend because there need to be several (hundred) self sustained servers that can act on their own when the connection to the others fails (which is likely rather than possible). But, as I just realised - in an internet context, isn't it possible that something like this could happen without even being part of a design? One ZOPE server's object, say, LibraryManager, calls an object in another ZOPE server, say UniversityLibrary, via XML-RPC (because it doesn't even know it's ZOPE). It asks it for a book. The University Library doesn't have it, but it has a service that looks in all the libraries it knows and returns any found occurences. Thus, at some point during that call, it asks the first server's LibraryManager about the book - again, not even knowing that it is a ZOPE server, via XML-RPC. Should this work, and where does it differ from what I'm doing? The problem is that it isn't my design, and the design is part of a contract. I can't really do anything about that (the major problem is that there will be SOAP components that might even need to be transparently integrated - which completely excludes ZEO). Why do you think that? ZEO is simply a single point of persistence for a group of Zope Application Servers. But what if I don't know which components are ZOPE, and components can be transparently exchanged?

What of programs running on an operating system that call other programs via that operating system? I don't believe you. You have a client application calling your Zope server's bla() function. It can do this either by HTTP or XML-RPC by choosing the appropriate Content-Type. You've chosen to implement this interface by making other XML-RPC calls to the same server to complete the task. This is both unnecessary and bad. Unnecessary because you're doing an RPC when you've got all you need in local memory. This is bad because you're introducing the additional overhead of setting up said RPC. Worse, you're now responsible for your own transaction management because you've split the task across multiple ZODB connections. You need to think about the *correct* way to write your bla() function. In doing this, you want to be able to take advantage of the automatic rollback facilities of Zope by keeping all of this in one transaction, which will also avoid your initial problem of conflict errors.

Re: [Zope] XML-RPC
Hi Jason, I've been working with Flash some lately as well.. with an eye toward useful vector graphics for Zope. There is a library called ming (http://www.opaque.net/ming) with a (SWIG'ed) python extension that I've been slowing working through, adding wrapping fuctions and getting to the point of Zope'ability. Ming is a 'swf' creation library with no connection to Macromedia. Something like this would free folks from the need to buy 'MM Flash' to work with swf output. It also would make a great way to generate swf 'on the fly' within Zope..

1. External method: Replaces the ZMySQL database connection
with an external Python function called 'mysqldb_XML', pieces
of which follow:
def mysqldb_XML(self,query):

dh=writer.PrettyPrinter(out,dtdinfo=info)
try:
p.setDocumentHandler(dh)
return p.parse(query)
except IOError,e:
return in_sysID+": "+str(e)
except saxlib.SAXException,e:

Inside Zope, I get the ZSQL 'query' and do something like:
dtml-call "RESPONSE.setHeader('content-type','text/xml')"
dtml-in "mysqldb_XML(query)"
dtml-var sequence-item
/dtml-in
2. XML-RPC: It seems to me XML-RPC could do this too, but
I don't know how one would print out the raw XML response.
Could I have a Zope client request the ZSQL method above,
but instead of sending it to my output DTML method, I just
print the raw-XML stream? Examples would be helpful:-)
It seems to me if XML-RPC already produces an XML formatted
stream, it would be more efficient to just use it (unless
there is yet another way in Zope I'm not aware of). Is it
possible? Is there any reason to want to use the external
method instead?
Thanks for your comments,

import sys,urllib
#Our MySQLdb XML driver;
driver="xml.sax.drivers.drv_mysqldb"
.
out = sys.stdout;
p=saxexts.make_parser(driver)
dh=writer.PrettyPrinter(out,dtdinfo=info)
try:
p.setDocumentHandler(dh)
return p.parse(query)
except IOError,e:
return in_sysID+": "+str(e)
except saxlib.SAXException,e:
return str(e)
Inside Zope, I get the ZSQL 'query' and do something like:
dtml-call "RESPONSE.setHeader('content-type','text/xml')"
dtml-in "mysqldb_XML(query)"
dtml-var sequence-item
/dtml-in
2. XML-RPC: It seems to me XML-RPC could do this too, but
I don't know how one would print out the raw XML response.
Could I have a Zope client request the ZSQL method above,
but instead of sending it to my output DTML method, I just
print the raw-XML stream? Examples would be helpful:-)
It seems to me if XML-RPC already produces an XML formatted
stream, it would be more efficient to just use it (unless
there is yet another way in Zope I'm not aware of). Is it
possible? Is there any reason to want to use the external
method instead?
Thanks for your comments,

RE: [Zope] XML-RPC and Zope
Lots. If you have Zope 2.2, see the API Documentation in the help system. -Original Message- From: Gijs Reulen [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 02, 2000 8:33 AM To: Mailinglist Zope Subject: [Zope] XML-RPC and Zope Hi there I am experimenting with XMP-RPC and Zope: I want to manipulate things from Borland Delphi. I got the example from the XML-RPC working, but now I wonder what other commands besides 'objectIds' are valid for Zope. For example, how can I determine which type each object in a folder is and how can I retrieve and store (change) the contents of an object ?
