[Zope] XML-RPC encrypted?

2006-01-25 Thread José Carlos Senciales

Hello,

I need to use XML-RPC to call some functions of a product in zope, but all 
my xml-rpc conections

has  user:[EMAIL PROTECTED]:port\folder\method

I´m wondering if it´s possible to do a call with xml-rpc with all data 
encrypted... with ssl...?


Thanks.

I'd use forward-Slashes /// in URLs anyway ;))

And yes, SSL works and you dont send user:password in
an url to the server - the client will/should build
a real BasicAuth-Header out of it (which you better
transport over ssl anyway)

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).

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

It is not possible to do _really_ explicit transaction management with

 If you really must architect your solution this way, then you are going
 to have to do your own transaction management.  Your 'local' calls need
 to do explicit commit() calls and you're going to have to reread
 'tainted' objects.

 Again, it will take you half an hour to modify your design instead of
 half a year to get all the bugs out of your implementation.

Of course it is. But you're talking about Zope here, not ZODB. Zope 
manages transactions so users don't often have to worry about them. If 
you want to manage transactions within Zope, the nyou have to understadn 
and co-operate with the transaction management that Zope does...

Re: [ZOPE] XML-RPC within ZOPE

2005-12-12 Thread Jan-Ole Esleben
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?

[Zope] XML-RPC within ZOPE

2005-12-11 Thread Jan-Ole Esleben
Hi!

Is it at all impossible to use XML-RPC _within_ a ZOPE architecture?

What I mean is:
I have a nested call structure:

1. Python script calls a method from a ZODB object
2. That method calls a Python module function
3. That module function dispatches an XML-RPC call to the same ZODB
object called in step 1
4. This last call, which is rather complex, returns, and all the calls
leading up to it return, sometimes doing some minor work

When I use the same code _without_ any XML-RPC (the Zope server's self
instead of the XML-RPC server object for that server), it works just
fine. When I use XML-RPC, I get a ConflictError during the final
return (from step 1), and I get it if I commit manually beforehand, so
it must be the commit triggering it.

The tricky thing is: nothing in my ZODB changes. I have several
mutable _arguments_ that are passed on, but they are not default
arguments and they don't get written to the ZODB.

Is what I'm trying to do impossible for some reason? Or can I just
make the whole call take place outside any transactions?

Thanks in advance for any pointers, I'm really a little desparate at this point.

 It really *is* in your interests to ensure a single request completes
 all your functional requirements ;)

That's not possible unfortunately. The design of the system is rather
complex, and unalterable in this respect. However, it is not true that
it is usually possible to fulfil this requirement. What of programs
running on an operating system that call other programs via that
operating system?

Given that that is a requirement that needs to be met, do I have any options?

 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.

[Zope-dev] Fat client thoughts, was: RE: [Zope] Zope + XML-RPC + native GUI

2002-01-22 Thread Jon Edwards

 No, I haven't done this, but I plan to do something like this to create a
 fat client to interact with content objects in a CMF site I am building.
 I've been playing around with wxPython and Boa Constructor
 (http://boa-constructor.sourceforge.net).  I'd be interest in finding out
 ways in which other people might be creating apps using these tools.

lots of good stuff snipped

Hi Sean

I don't know if you've seen PythonCard? ...newish GUI building app for
wxPython (a bit like Boa, but lighter) -
http://pythoncard.sourceforge.net/

On their mailinglist, they're discussing which DB to use as a (built-in)
persistent storage, and ZODB is one of the options -

http://www.geocrawler.com/lists/3/SourceForge/14884/0/7610885/

One of the samples that comes with Pythoncard is textRouter (also at
http://simon.kittle.info/textrouter) which is a wxPython client that uses
XML-RPC to post to Blogger or Manilla sites via their APIs. Looks like it
could give you a headstart in developing your CMF-GUI? (If you're looking
for collaborators, I'd be keen to get involved!)

(BTW has anyone implemented the Blogger API -
http://plant.blogger.com/api/index.html - in Zope/CMF? I'm planning to try
it soon, so if anyone has any tips/code they wouldn't mind sharing, I'd be
very grateful! :-)

On a slight tangent, I also spotted a wxPython app called Gimini -
http://gimini.sourceforge.net/ It's officially a MindMapping tool, but I
thought the GUI could be adapted to make a nice drag-n-droppable sitemap
tool for CMF, a bit like the one in FrontPage! :-)

Hope that's helpful!

[Zope] XML-RPC problem solved!!

2000-12-22 Thread I-Min Mau

OK, with help of my boss we were able to get the xmlrpclib patch to work
with Authentication.

Basically I did as before, with a duplicated, modified version "xmlrpclibx",
and used it:

import xmlrpclibx

t = xmlrpclibx.BasicAuthTransport('myusername','mypassword')
# I have to create the new modified transport with this call!

s = xmlrpclibx.Server("http://0",t)   # and passed t as argument!
print s.imin.short()

Then it worked.  I just didn't create the right object to pass in, that's
all.
Happy Holidays again, everyone!

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.. I'll try to
get a proof of concept working

Jason 1. Flash5 ActionScript is _very_ close to JavaScript

Jason vs. 13Mb I think + large user installed base.

Jason 3. Flash5 has new XML and XMLSockets objects which should
Jason integrate nicely with XMLRPC and Zope via some smooth

Jason 4. Flash will allow _much_ more client side interactivity
Jason than SVG

Jason 5. You can port SVG graphics to Flash using various tools
Jason [or even write your own].

Jason 6. You can still use SVG JavaScript and do some comparisons
Jason where appropriate...

Jason 7. Flash is more mature than SVG, though I agree SVG is
Jason developing very well. I expect we shall see some serious
Jason applications during next 12 months with it.

Jason 8. Flash is very object-oriented once you grok to its
Jason design. Thus mirrors Zope very well.

Jason CONS:

Jason A. Flash has steepish learning curve, but high payback and
Jason reusability.  [Not as tough as Zope :-) ] B. SVG is fully
Jason open; the Flash spec is 'published' but not open in the
Jason same way.  C. must be more but cant thing of them right now

Jason If you are interested contact me - I have lots of useful

2000-11-08 Thread David Nimmons

I am trying to develop a web based interface to automation equipment (Allen
Bradley plc's in this case) to use for an operator interface. I am using
SVG to develop graphics and want to use javascript to manipulate the
graphics based on data from the plc. I am looking for a way to pull more
data from the server without having to reload the page. My question is will
XML-RPC allow this. Or does Zope have some other mechanism that would allow
this. Thanks for any help.

Actually this is mainly a client-side problem, on server side you have
total 
freedom to serve any protocol ;)

Often this kind of problem is solved by having twho frames and data is
aquired 
by reloading the "data-page" which then manipulates the
"presentation-page" 
using javascript, possibly in its onLoad method.

Re: [Zope] XML-RPC

2000-11-08 Thread Phil Harris

Another possibility is to use IE on the client side and use one of the COM
interfaces to XML-RPC.

You could then use javascript/vbscript to get data as required.

Re: [Zope] XML-RPC

2000-11-08 Thread Jason Cunliffe

Hello

I am missing the start of this thread, so I may be off topic, but you might
want to look seriously at Flash5 for the client side programming and
graphics.

PROS:

1. Flash5 ActionScript is _very_ close to JavaScript

2. Flash Player/Plugin is much smaller than SVG 300Kb vs. 13Mb I think +
large user installed base.

3. Flash5 has new XML and XMLSockets objects which should integrate nicely
with XMLRPC and Zope via some smooth Python external method programming.

4. Flash will allow _much_ more client side interactivity than SVG

5. You can port SVG graphics to Flash using various tools [or even write
your own].

6. You can still use SVG JavaScript and do some comparisons where
appropriate...

7. Flash is more mature than SVG, though I agree SVG is developing very
well. I expect we shall see some serious applications during next 12 months
with it.

8. Flash is very object-oriented once you grok to its design. Thus mirrors
Zope very well.

CONS:

A. Flash has steepish learning curve, but high payback and reusability.
[Not as tough as Zope :-) ]
B. SVG is fully open; the Flash spec is 'published' but not open in the same
way.
C. must be more but cant thing of them right now

If you are interested contact me - I have lots of useful research on this
topic.

Re: [Zope] XML-RPC vs External method?

2000-11-02 Thread Irene Barg

Kapil,

Thank you for this simple solution!  I'm new to XML and Zope
and sometimes I get caught in learning too many new things
at once, we forget to think "simply":-)  Thanks to you, I
don't need to use either External method, or XML-RPC.  The
following simple DTML method works:

dtml-call "RESPONSE.setHeader('content-type','text/xml')"
?xml version="1.0"?
program
dtml-in get_all_programs
 row
adassnumdtml-var adassnum null=""/adassnum

  /row
dtml-else
  !--There was no data matching this query.--
/dtml-in
/program

Thanks again!

[Zope] XML-RPC vs External method?

Hello all,

Zope.  It consists of:

with an external Python function called 'mysqldb_XML', pieces
of which follow:

 For example, how

[Zope] (XML-RPC) Calling Database.manage_pack

2000-07-21 Thread Oleg Broytmann

Hello!

   I wrote a simple script to pack Data.fs on a regular basis. It is very
simple, actually, just
   
urllib.urllretrieve("http://my.zope/Control_Panel/Database/manage_pack?days:float=3")
(a little bit harder than that, but I did it)

   Now I am trying to achieve the same with XML-RPC. No luck. How can I
pass "days" parameter?

   server = xmlrpclib.Server("http://my.zope", BasicAuthTransport(login, password))

   server.Control_Panel.Database.manage_pack(3) does not work - Zope
returns an error abou invalid value,

   server.Control_Panel.Database.manage_pack(days=3) does not run at all -
args expected to be a list, not a hash...
