Re: [IronPython] Using ruby module from python.

2009-12-01 Thread Pavel Suhotyuk 
I try your example. It's really work, but have some problem with ruby 
objects:

1) Can't call RubyObject methods.
>>> import clr
>>> wsdl = clr.Use('wsdl.rb', 'rb')
>>> factory = wsdl.get_factory()
>>> client = 
factory('http://localhost/PaymentsBroker/Manager/ProviderService.asmx?WSDL').create_rpc_drive()

Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'RubyObject' object has no attribute 'create_rpc_drive'
>>> client = 
getattr(factory('http://localhost/PaymentsBroker/Manager/ProviderService.asmx?WSDL'), 
'create_rpc_driver')()

>>>

2) Calling methods without parameters possible.
>>> client.GetProviders(None)
[#]>


But I don't understand how call methods with parameters. In ruby I can 
call like this:

>>> print client.GetBalance(:providerId => 3).getBalanceResult().balance
60663.89=> nil
In python it's not work:
>>> client.GetBalance(3)
Traceback (most recent call last):
  File "", line 1, in 
SystemError: SOAP::Mapping::MappingError
>>> client.GetBalance(provider=3)
Traceback (most recent call last):

The easiest way how to get WSDL factory instance would be to write a simple 
Ruby script that loads it:

== wsdl.rb ==

require 'soap/wsdlDriver'

def get_factory
  SOAP::WSDLDriverFactory
end

And then you can do:

import clr
wsdl = clr.Use('wsdl.rb', 'rb')
factory = wsdl.get_factory()
print factory("x.wsdl")

get_factory method is exposed on the "wsdl" module so that Python can call it. 
IronRuby doesn't yet implement dynamic protocols for constant access so you need the 
get_factory helper for accessing Ruby constants.
Also we have some work to do to make clr.Use work better with libraries of 
other DLR languages.
Let us know if you hit some other issues.

Re: [IronPython] Web Services library

2009-11-30 Thread Pavel Suhotyuk 

Thank you for the answer.

Yes, I know about this way, but we have a part of processing system. 
This component compile and run many scripts and we want to have dynamic 
way to construct/destruct SOAP classes.


David Escobar wrote:
One way to do it is to use the /wsdl.exe/ tool to generate a proxy 
class. The tool will generate the proxy class in C# (it can't do 
IronPython code), but you can then take the resulting .cs file and 
compile it to a .dll (using the C# compiler - /csc.exe/). Place the .dll 
into the same folder as your IronPython program and add a reference to 
it from your IronPython code using the *clr.AddReference* method. 
Something like this:


*import clr
clr.AddReference("MyServiceProxyClass.dll")
*
There may be other methods as well, which I'm not aware of, but this is 
the way I would do it. The easiest way to get to /wsdl.exe/ and 
/csc.exe/ is to open up the Visual Studio command prompt, which puts all 
of these tools in your path - that way, you don't have to go hunting for 
the tools yourself.

You're only using 1 ScriptEngine class?  That should be fine based upon

Is citypay.utils being ran multiple times when you run the code in the
multi-threaded scenario?  If you have a console app you could put a 
print statement in utils.py to see if it's getting executed multiple

times.  If it's not a console app you could put some other logging
into it.  Executing Struct's definition multiple times might cause 
the exceptions you're seeing but I don't know why it would get executed

multiple times.

[IronPython] IPY and multitasking

2009-11-12 Thread Pavel Suhotyuk 

I have this collection of methods:
--
public static class IronPythonHelper
{
public static ScriptEngine 
CreateScriptEngine(IEnumerable paths)

{
var langSetup = ScriptRuntimeSetup.ReadConfiguration();
var engine = new 
ScriptRuntime(langSetup).GetEngine("IronPython");

var path = engine.GetSearchPaths();
path.Extend(paths);
engine.SetSearchPaths(path);
engine.Execute("import citypay", engine.Runtime.Globals);
engine.Execute("import cPickle", engine.Runtime.Globals);
engine.Execute("from citypay.utils import Struct", 
engine.Runtime.Globals);

return engine;
}

public static object PackParams(ScriptEngine engine, 
IDictionary param)

{
var scope = engine.CreateScope();
engine.Execute("from citypay.utils import Struct", scope);
engine.Execute("def pack( params ) : return 
Struct(**dict(params))", scope);
var pack = scope.GetVariableobject>, object>>("pack");

return pack(param);
}

public static byte[] CPickleSerialize(ScriptEngine engine, 
object obj)

{
var scope = engine.CreateScope();
engine.Execute("import cPickle", scope);
engine.Execute("def serialize( obj ) : return 
cPickle.dumps( obj )", scope);
var serialize = scope.GetVariablestring>>("serialize");

return Encoding.Unicode.GetBytes(serialize(obj));
}
}
--
I have base class used for create needed Engine and Scope as:
--
public absract class SripterBase {
private static readonly ScriptEngine engine = 
IronPythonHelper.CreateScriptEngine(Settings.Default.PythonLibPaths.Cast());


...
}
--
My problem in next: Scripter based classes can be created in many 
threads in one time.
Scripter class used for get pickle'd data by CPickleSerialize(), from 
something like:

--
class Struct ( object ) :

def __init__ ( self, **kwds ) :
for name, val in kwds.iteritems() :
setattr( self, name, val )

def _update ( self, **kwds ) :
for name, val in kwds.iteritems() :
setattr( self, name, val )

def _enum ( self ) :
return [( a, getattr( self, a ) ) for a in dir( self ) if 
a.find( '__' ) == -1 and not a.startswith( '_' )]


def __repr__ ( self ) :
return '' % ' '.join( [ '%s=%s' % ( str( n 
), repr( v ) ) for n, v in self._enum() ] )


def __eq__ ( self, other ) :
if not isinstance( other, type( self ) ) :
return NotImplemented
return self._enum() == other._enum()
--

Multithread code in some (not stable) cases throws 'strange' exceptions.
This problem exists only in multithreaded environment and not exist in 
single thread.


How I can fix or avoid this problem ?

How can I create script object without code generation same like:

scriptEngine.Execute(string.Format("{0}()","Broker"),scriptScope);

?

2.6 ships.

The preferred way to do this though is to do a GetMember where
T is a delegate type with > 3 paraemters.  Then you can just invoke
the delegate.

and try to call methods by this c# code:

Invoke validation method is success, but invoke check method throws

Looks like 2 paramters called correct, but more than 2 throws exception
