Hello All,
I am running into a frustrating exception. When attempting to instantiate a class with an argument that is an instance of a different class from a separate assembly, I receive an unhelpful type error from the IronPython interpreter:
TypeError: expected XYZPositioner, got XYZPositioner
Both assemblies were loaded using clr.AddReferenceToFileAndPath. I have tried to confirm the type of the object I am passing as an argument to the constructor:
> A.GetType() == Target.Devices.XYZPositioner
True
Is there any way to get more information about the error? (The message reminds me of my days working in OCaml, where all of the error messages were translated from French grammar and it was never clear how to differentiate the object from the subject)
Thanks,
Matt Bakalar

Any chance you can put a print in any calls to dlopen in ctypes\__init__.py and see what we're trying to load?

It looks like on Linux the -X:ExceptionDetail command line option is being passed which is preventing the stack trace from having any line number information - or maybe the stack trace is cut off?  Either way it'd be useful to see the line number which is calling dlopen to understand what library we are failing to load.  My guess would be that it's trying to load the Python library but I'd think that would work fine (it looks like we pass in a null path in that case which should be alright for dlopen).

This is caused by having the same assembly loaded into 2 different loader contexts at once (loader contexts are a part of the CLR loading infrastructure).  Adding references to assemblies by file can be tricky.  One possible solution might be to install both assemblies into the GAC and then do clr.AddReference.  Another might be to make sure they're next to ipy.exe (or whatever the host process is if it's not ipy.exe) and then also do a clr.AddReference.  You could also attempt to debug where the assemblies are getting loaded and try to make the add reference to file work - that would involve using fuslogvw.exe (logging all loads) and probably looking at PythonContext.TryLoadAssemblyFromFileWithPath.  But the other choices are probably much easier and more robust.

Hi,
In IronPython 2.6 I ran the following code:

class A(object):
     def f(self):
             self.__delattr__('x')
a = A()
a.x=1
a.f()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in f
AttributeError: 'A' object has no attribute 'x'


This code runs ok on cpython so I'm guessing this is bug...

Both on OSX and Ubuntu it appears to fail on a call to PyDLL(None).  The
problematic call is from the block:

if _os.name in ("nt", "ce"):
    pythonapi = PyDLL("python dll", None, _sys.dllhandle)
elif _sys.platform == "cygwin":
    pythonapi = PyDLL("libpython%d.%d.dll" % _sys.version_info[:2])
else:
    print "DEBUG: NOT NT/CE OR CYGWIN."
    pythonapi = PyDLL(None)

It goes to CDLL base class and dies exactly here:

if handle is None:
    print "HANDLE: " + str(self._name) + str(mode)  #prints None0
    self._handle = _dlopen(self._name, mode)
    print "AFTER DLOPEN. DOESN'T PRINT."

Hope this helps.

Tristan

I am running into a frustrating exception. When attempting to instantiate a class with an argument that is an instance of a different class from a separate assembly, I receive an unhelpful type error from the IronPython interpreter:
TypeError: expected XYZPositioner, got XYZPositioner
Both assemblies were loaded using clr.AddReferenceToFileAndPath. I have tried to confirm the type of the object I am passing as an argument to the constructor:
> A.GetType() == Target.Devices.XYZPositioner
True
Is there any way to get more information about the error? (The message reminds me of my days working in OCaml, where all of the error messages were translated from French grammar and it was never clear how to differentiate the object from the subject)
Thanks,
Matt Bakalar

Couple of follow up questions (a simple repro isn't working for me):
	Is this on your Mac?
	What locale is your machine set to?  I'm guessing it's something like
en-UK (or whatever the Mac equivalent is if it's different) or do you have it
set to a German locale?

If you're willing to try an experiment to re-build IronPython you could try 
changing the "v.IndexOf(oldString, start)" call in StringOps.cs to be:

v.IndexOf(oldString, start, StringComparison.Ordinal)

I think that's the only culture sensitive code path in our replace 
Implementation and so my guess is that's the problem.  If you can't rebuild
and try it out I can probably track down a Mac to try the repro on.

Yes, sorry - it is with Silverlight 4 and IronPython 2.6.1 on the Mac. 
It reproduced for both myself (English locale) and on my colleague who 
has a German machine. I don't know how easy it is to compile IronPython 
for Silverlight - it certainly wasn't easy a while ago but I can try 
again. :-)

All the best,

Michael

Subject: [IronPython] clr.CompileModules fails on some python standard lib
	modules
Message-ID: <AANLkTimg9J3mTO3-QHdUF6Ebm7QEEVmItNx0uvZ9BzYV@mail.gmail.com>

Several standard lib modules fails to compile through the use of
clr.CompileModules(..). Compiling modules like decimal.py, gettext.py,
glob.py and others (nine in total) all fail with the same message:

SystemError: CompileToMethod cannot compile constant
'IronPython.Runtime.Types.BuiltinFunction' because it is a non-trivial
value, such as a live object. Instead, create an expression tree that
can construct this value.

Is this a known problem? Are we expecting too much trying to compile
the standard library with clr.CompileModules() and this is not a
supported behaviour?

We are using IronPython 2.6.1 for .NET 2.0.

Regards,
-Hern?n.

This is a known issue 
(http://ironpython.codeplex.com/workitem/26593?ProjectName=ironpython) 
and as Dino mentioned recently it is already fixed in the main.

Which brings a question - when is IronPython 2.6.2 scheduled for release?

We haven't quite scheduled it yet - we've been waiting to make sure there were
no other regressions introduced in 2.6.1.  I've seen 1 or 2 other small bugs
that I think we'd like to fix.  Personally I'm thinking end of June-ish but I'll
need to talk to the rest of the team about it.

For me, the biggest issue is the compiling. Would be nice to see some 
progress in compiling Silverlight code ;-)

Also the line number issue in tracebacks is quite inconvenient 
(http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=26940). 
I've almost got used to it but it surprise me from time to time anyway.

End of June/ start of July is fine for next release.

Hello I am trying to import the Zlib module after I have installed the DLL

I am getting a no module named zlib

It probably has something to do with my environment variables, what do I

IRONPYTHONPATH C:\IronPython\DLLs\;

Hello Andrew,

I haven't tried this, but I assume you have to add a reference to the 
assembly before you can import from it. Try:

     import clr
     clr.AddReference('IronPython.Zlib')

(Substitute the correct name of the dll into the AddReference call.)

HTH,

Michael Foord

This shouldn't be necessary, as any DLL in the DLLs folder is
automatically referenced, but it is worth trying. If it fails, it
might provide a more useful error message.

Andrew: You shouldn't have to set any environment variables to use
IronPython.Zlib; I have a feeling that, for some reason, the DLL is
failing to load. Which versions of IronPython and IronPython.Zlib are
you using? What path is your IronPython installed to?

That was going to be my next suggestion :). There is also a .NET 4
version of IronPython.Zlib available from
http://bitbucket.org/jdhardy/ironpythonzlib/downloads.

It would be nice to have one version for both but with the changes
from .NET 2 to .NET 4 DLR I'm not sure that's possible.

Subject: [IronPython] IronPy Tools - updates?
Message-ID: <AANLkTimmZ39n4CQboAXMtmtkxiO1QIstwuLuBJOExC-0@mail.gmail.com>

Hi,

Just wondering what the outlook is for an update to IronPy Tools for
VS? Normally I don't bug developers about this, but my motivation for
asking this time is that I've actually stopped using it.

I've been working on a Word document that's in my project root folder
(-1 for putting binary files under version control, though TortoiseSVN
nicely hooks into Word's 'compare documents' feature) and every time I
save it - AFAICT, literally every time - VS crashes and restarts. I
suspect it's to do with the temporary files that Word creates when
saving and the implicit project feature of IronPy Tools, since this is
already known to dislike things changing too quickly.

(Yes, I could copy my document to another directory to work on it.
Nobody else is touching the doc except me at the moment, but it turns
out to be less painful to use Explorer and Notepad2 to get through the
project for when I need a quick code reference.)

I'm keen to keep sending feedback/bugs, though it's tough at this
stage when the major issues in CTP2 are probably fixed or updated out
(plus it would help my tester-fatigue to get a newer version :) ).

Cheers,

Steve

Could this be because we don't have a grid or canvas in the default template for
a window?  With our default templates I get this same experience (grey out, nothing
happens) for both 3rd party and normal WPF controls.  If I add a Canvas or a Grid
then I'm able to drag and drop controls onto the surface.

There's still issues at that point of not actually having the references added but
I think if I made sure the assemblies were deployable and did a clr.AddReference
then it'd work (we have plans to improve that).

So I think we just need to update the template to match the same sort of template 
that C# produces by default.

Bummer you've reached the point of unusability....  We'll probably try
and get a new release out in the next couple of weeks.  I'm at TechEd
all next week but I still might be able to produce the build and go
through all of the release process remotely.  If not it'll have to wait 
until the week after that.

Sounds great. My next couple of weeks are put aside for documentation
purposes anyway, so there's not much coding on the cards anyway.

Subject: [IronPython] how to convert C# MarshalAs code to IronPython
Message-ID: <AANLkTil6PHB7LhGagDL1T4BMDy64STk4TVE8vqOn0L3j@mail.gmail.com>

Hi,
    I have the following C# code and I am trying to do the same
functionality in IronPython, any help is appreciated.

I was trying to do the same functionality in IronPython using the clrtype.py
from the IronPython-2.6-Samples and I am able to connect to the library and
the function but I am having trouble passing array of strings. With the
current code it only passes the first letter and then it crashes.

I am trying to call  cwavec(int, int, char *) and it is a C function which
is part of the vniwave.dll and I am trying access it in IronPython.

C# code:

namespace PVWave
{
    public class OPI
    {
        [DllImport("C:\\datk_code\\VNI\\wave\\bin\\bin.i386nt\\vniwave.dll",
            EntryPoint = "cwavec",
            ExactSpelling = false,
            CharSet = CharSet.Ansi,
            SetLastError = true)]
        public static extern unsafe int cwavec(Int32 action, Int32 nCmds,
            [MarshalAs(UnmanagedType.LPArray, ArraySubType =
UnmanagedType.LPStr, SizeParamIndex = 10)] string[] cmds);

    }
}

Here is my attempt in IronPython:

import clrtype
import System
import sys

class OPI(object):
    "Description of Class"

    # Note that you could also the "ctypes" modules instead of pinvoke
declarations
    __metaclass__ = clrtype.ClrClass

    sys.path.append("C:\\datk_code\\VNI\\wave\\bin\\bin.i386nt")

    from System.Runtime.InteropServices import DllImportAttribute,
PreserveSigAttribute
    DllImport = clrtype.attribute(DllImportAttribute)
    PreserveSig = clrtype.attribute(PreserveSigAttribute)


    @staticmethod
    @DllImport("vniwave.dll")
    @PreserveSig()
    @clrtype.accepts(System.Int32, System.Int32,
System.Array[System.String])
    @clrtype.returns()
    def cwavec(action, nCommands, commands): raise RuntimeError("this should
not get called")

def call_pinvoke_method_pvwave():
    print "Calling pinvoke pvwave methods:"
    actionNum = 2
    nCommands = 1
    commands = System.Array[System.String](['PRINT, "Connected to PV-Wave
from IronPython"'])
    print "cwavec(action, nCommands, commands):"
    OPI.cwavec(actionNum, nCommands, commands)

call_pinvoke_method_pvwave()

Thanks

Subject: [IronPython] Dynamic keyword, Ironpython and Silverlight?
Message-ID: <AANLkTilIlAX4kLGQMCRQ06DD5-EDjWbDfQeH-3OCz2PJ@mail.gmail.com>

Sorry if I've double sent this mail but I wasn't registred the first time
and I'm not sure it got through:

Is it possible to access IronPython code by using the dynamic keyword in
Silverlight 4? I've found some examples like below:

            var ipy = Python.CreateRuntime();
            dynamic test = ipy.UseFile("test.py"); //This throws "The method
or operation is not implemented."
            test.Simple();

But I cannot get it to work in Silverlight. You can see the error message I
get. If it is possible, can someone point me to a working sample?

Thanks for help!

Did you add this reference Microsoft.CSharp.dll? You should add this
reference so that the dynamic keyword can work in the code.

You'd need to decorate the string array parameter with a lot more
information -- it's an ANSI string rather than a Unicode string, for
instance, and there's another parameter that describes the length of the
array. But I just looked at the code for clrtype.accepts, and it doesn't
appear to support decorating the parameter types with additional attributes.
If you can get at the TypeBuilder -- and I know this used to be possible --
then the easiest way to implement this is probably just to call
TypeBuilder.DefinePInvokeMethod directly.


Is there a typo in the C# code? It looks like SizeParamIndex should be 1 and
not 10.

Subject: [IronPython] Dynamic keyword, Ironpython and Silverlight?
Message-ID: <AANLkTimYeufLcMR9UtoAZ5y5vYohV71h6e05fwEmZ0Rd@mail.gmail.com>

In the example I attached I'm not even sure that the "dynamic" keyword is
the problem here. Even if I do like below (in silverlight):

            var ipy = Python.CreateRuntime();
            ipy.UseFile("test.py"); //This still throws the same exception

Does anyone perhaps has a working SL example that I can look at where the
dynamic keyword is used with python files?

Thanks for your help!

Is it a good approach to use clrtype.py or is there a better way to call the
C function from IronPython...

Also, the SizeParamIndex works ok when it is set to 10 in VS2005, but it
does error out when used in VS2010, then I set it to 1.

Thanks

Try using ctypes (http://docs.python.org/library/ctypes.html) instead.
It's a lot easier to use than P/Invoke, and your code should work on
any Python implementation instead of just IronPython.

Our current app is Python based and I wanted to move to IronPython because
of the .NET and WinForms. I have it working well with Python and swig and
now I am trying to figure out how to do it using IronPython.

I am very curious whether is there any direct conversion from C# code from
my first post/email to IronPython code???

Thanks

Jeff,
    I think I miss read your reply, what you are saying is that if it based
on ctypes it will work in IronPython as well is it?? I thought you needed
IronClad and so on make it work.

Subject: [IronPython] How should I install packages?
Message-ID: <huipht$afa$1@dough.gmane.org>

I've got an all-python package that should be compatible with
ironpython.  It seems like distutils.setup doesn't exist though, so my
original setup.py script won't work.

I might tweak my setup.py so that when it can't find a distutils.setup,
it goes into "ironpython mode" and then just manually copies stuff.

So where should I install stuff?  Just copy it somewhere in sys.path?

Is there a convention other people are following?

Matt

PS and OT: I'm trying to use gmane to access this mailing list with slrn (a
command-line newsreader) and while I can post to the list, no new posts
ever show up.

I use gmane and slrn to read a lot of other lists and they work fine.
Any ideas?

Subject: [IronPython] Multi threaded engine
Message-ID: <000301cb0643$6076b940$21642bc0$@com>

I am investigating different possibilities regarding multithreading and Iron
Python and I would appreciate some pointers.

What I am currently doing is I allow the user to enter some pseudocode that
will become some business logic running in a high traffic application
server. 

The main properties of this project is that the user has to be able to
change these rules ad hoc and then ask then server to load the rules. The
server will load the rules convert these to IronPython, compile the code and
then for each message run the compile code against some parameters retrieved
from the message.

 

Since there are hundreds of messages coming in the server per second to make
this work with multiple threads I  defined the ScriptEngine and the
CompiledCode as  [ThreadStatic]. Therefore every time I have to use the
engine and the engine is null I will create a new engine (one per thread).
Then I will retrieve all the rules from the DB convert the rules to Python
code, and compile the code using engine.CreateScriptSourceFromString(),
source.Compile.

Then to run the rules on the message I create a
Microsoft.Scripting.ScopeStorage, call .SetValue to set each parameter that
I want to be used by the script, then use the engine to CreateScope and use
the compiled code and that Scope to execute the script.

 

Everything seems to work fine but I am wondering if this is the proper way
to do this. I have not seen anywhere any references to multithreaded uses of
IronPython and this creates some uncertainties to me. What I would like to
know is if there is a  more elegant and faster way to do this, since the
rules start getting bigger and bigger and this slows down both compilation
and execution of the scripts. 

 

I am thinking that it could be better if the ScriptEngine and CompiledCode
are thread safe, and if I create one static engine an one static
CompliledCode then this will minimize the compile time since the rules will
have to be compiled one time and then reused for all threads. 

 

Anyway any tips on running dynamic IronPython code are welcome.

Yeah, with ctypes IronPython can call native code directly - it
actually uses P/Invoke behind the scenes to do it. Python also
implements ctypes, as do Jython and PyPy, so any code that you write
using ctypes should work on any Python implementation.

I haven't tested this (seeing as I don't have the exact DLL) but it
should be pretty close:

from ctypes import *
vniwave = CDLL('vniwave.dll')

cwavec = vniwave.cwavec
cwavec.restype = c_int
cwavec.argtypes = [c_int, c_int, POINTER(c_char_p)]

The only part I'm not sure about is the string[] - I'm assuming the C
function takes a char**.

Alternatively, you could write the P/Invoke declarations in a C# class
library and load that into IronPython using clr.AddReference, but I'd
recommend using ctypes.

My understanding is that this is the case - for NWSGI I use a single
engine (per AppDomain, but that's not important) and each script is
compiled once into a CompiledCode object. On each request it gets a
new scope from the engine, finds the CompiledCode for the requested
script, and executes it in that scope. IIS can have a lot of worker
threads handling requests at any time, so it's basically the same
scenario you have. As long as you don't reuse scopes (and they're very
cheap to create) you should be just fine.

This is correct and is definitely the recommended way to do this.  The

What do you mean be "see"? One script could potentially examine the
code of another script in the same script engine?

Hi,
   In Python I am used to using enthought's Traits to validate attributes
and explicitly declare variable types, is there anything similar to that in
IronPython. Also, when I try to import enthought's traits module (with
ironclad) in IronPython I get ImportError: No module named zipimport is
there a way around to get around this??? is IronPython compatible with
setuptools??

Thanks
Ash

There isn't a zipimport for IronPython, unfortunately. It's also the
big hurdle preventing setuptools/distribute from fully working (it
mostly works, if you can avoid zipped eggs). I tried to get it to work
a long time ago but never had time to finish it.

Thanks Jeff,
This is the recommendation I was expecting to get. 
I will run a high concurrency test on a single engine and single compiled
code, with new scopes for each request and see where it takes me.
Do I need any locks on the engine itself when Getting the scope (which could
be called from many threads at the same time)?

I have another question related to performance.
Right now I have a number of parameters that I need to pass to the
CompiledCode and I use Microsoft.Scripting.ScopeStorage.SetValue and then
create the scope using this.
Is there a more efficient way to pass parameters to the CompiledCode? Like
creating an single "parameter" object which is well known by both the
IronPython code and my C# code?

Thanks 
Christos

My understanding is that this is the case - for NWSGI I use a single
engine (per AppDomain, but that's not important) and each script is
compiled once into a CompiledCode object. On each request it gets a
new scope from the engine, finds the CompiledCode for the requested
script, and executes it in that scope. IIS can have a lot of worker
threads handling requests at any time, so it's basically the same
scenario you have. As long as you don't reuse scopes (and they're very
cheap to create) you should be just fine.

It looks like Traits itself isn't dependent on zipimport (it depends
on setuptools, which requires zipimport), so you should be able to get
away with putting an empty zipimport.py file somewhere on sys.path.
I've done this before to get things setuptools stuff working; as long
as it doesn't try to *use* zipimport, you're OK.

I don't know of anything else that works the same, but it should be
possible to make it work, if you can get IronClad to handle the C
portion of it (they don't have a pure Python version, *grumble
grumble*).

The engine should handle those locks itself, but I don't have the
source handy to check for sure.

Hi Peter,
I just did this myself; starting with the times that I parsed out from a
TextBox, plus the yr/mo/day values from 'now':
        from System import DateTime    *<== note: DateTime not datetime*
        new_time = DateTime(yr, mo, day, self.hh, self.mm, self.ss)

I did find some other ways to do this by googling, but this worked nicely
for me as I had already parsed/validated the TextBox time; I did also find
some suggestion that strptime might appear in a future release.... how
future, I can't say. Good luck!
Ken

	event handlers
Message-ID: <AANLkTilNvBshq3rsf2eEZ2KVU66yBUSVbHDeaT7uL1Oa@mail.gmail.com>

Hi,
I've got a whole stack of event handlers, assigned via the usual something
like....

my_button.Click += button_was_clicked

As it turns out, the initialization for the thing that has all these
handlers may need to be run several times, and it seems like I ended up with
multiple copies of the same event handler, and "button_was_clicked()" now
gets invoked multiple times for EACH time I click my_button. It seems to be
solved by just skipping the handler assignment if I've already done it
before, but it seems odd that the same EH would be assigned and fired twice.
Is this really what I'm seeing? I can see a case for assigning multiple *
different* EH's:

my_button.Click += event_handler_1
my_button.Click += event_handler_2

but then this begs the question, is there a defined order in which the EH's
will fire? I looked thru multiple python/IronPython books and googled, but
came up empty on both questions..... Hopefully someone here understands
these things better than I do....

For example you could import sys, publish an attribute on it, and another
script could read it.  Or you could go in and change "min" or "max" in
__builtin__.  Or you could go and mutate some read/write static field in
the .NET framework.  Basically while everything is thread safe there's 
no level of isolation between the scripts.  It's probably nothing to be
too concerned about I thought I'd mention it for completeness.

The best way is to create the storage for the scope yourself.  Right now
the simplest (and sure to work) way to do that is to implement IAttributesCollection 
and create a scope using that for the storage.  Then you can respond to
the lookups lazily.  But setting multiple variables on a scope shouldn't
be that expensive (at least in 2.6.1 - there were some issues w/ that in 
2.6).

These are CLR-level issues. The first basically comes down to the fact that
there's really no way to enumerate the handlers which have already been
added to an event. As for the second, there is no contract that defines the
order on which the handler will be called. But I suspect that the default
implementation of an event -- which corresponds to just declaring "public
event EventHandler MyEvent;" in C# -- would probably give consistent
in-order results.

Ah, got it - IIS isolates scripts using AppDomains anyway, so it
shouldn't be a concern for me.

Yep, that's it, that's the behavior.  Yes, it would be nice to have this behavior on by default for the Ipy templates.  At least I have a workaround.  Plans to streamline the AddRef process would be nice, too, looking forward to the next CTP, regardless of the aforementioned behaviors ;)

Thank You, Dino.

Could this be because we don't have a grid or canvas in the default template for
a window?  With our default templates I get this same experience (grey out, nothing
happens) for both 3rd party and normal WPF controls.  If I add a Canvas or a Grid
then I'm able to drag and drop controls onto the surface.

There's still issues at that point of not actually having the references added but
I think if I made sure the assemblies were deployable and did a clr.AddReference
then it'd work (we have plans to improve that).

So I think we just need to update the template to match the same sort of template 
that C# produces by default.

It would seem odder to me if you added an event handler multiple times 
and it *wasn't* called. :-)

The less programming languages read your mind and work out what they 
*think* you meant the better. If you don't want an event handler 
installed multiple times then don't add it multiple times...

The issue tracker for CPython  [if I read it correctly] lists
datetime.strptime as a new feature to be supported in python 2.7 and
3.2. It is not documented in the Python 2.6 manual.  The current way
of doing it seems to be:

>>> import datetime
>>> import time
>>> d = datetime(*(time.strptime(date_string, format)[0:6]))

I have not tested that, I just cut it out of the issue tracker.

And, Yes, you are running an obsolete version of IronPython. You
should upgrade to 2.6. But that will not fix your problem, since
datetime.strptime is not present in the current version, either.

Thanks Dino and Jeff,
You guys are great, I was not expecting these fast responses.

Thanks again, I will do a number of changes based on your comments and see
if I have any issues.

Nope - no locks required.

The best way is to create the storage for the scope yourself.  Right now
the simplest (and sure to work) way to do that is to implement
IAttributesCollection 
and create a scope using that for the storage.  Then you can respond to
the lookups lazily.  But setting multiple variables on a scope shouldn't
be that expensive (at least in 2.6.1 - there were some issues w/ that in 
2.6).

datetime.datetime.strptime is definitely in CPython 2.5 and 2.6:

"""
tony-meyers-imac:~ tameyer$ python
Python 2.5.1 (r251:54863, Feb  6 2009, 19:02:12)

Type "help", "copyright", "credits" or "license" for more information.
>>> import datetime
>>> datetime.datetime.strptime("2010 06 08", "%Y %m %d")
datetime.datetime(2010, 6, 8, 0, 0)
"""

The only IP 2.6 I have handy is trypython.org, and the above code does
fail there (no copy and paste from the site unfortunately).

This is a known bug (so go vote!):

Subject: [IronPython] deepcopy
Message-ID: <SNT104-W34079891A74A8535CA88DED0D60@phx.gbl>


Hi there,

part of this question was posted by one of my co-workers in SO, but I thought it wouldnt hurt making it here too and more specific.

We wanted to use deepcopy in an IronPython 2.6 asp.net webforms project. We abandoned the idea because it brought
as conflict with a dll we use (cooperator.framework.web.dll) . It said an attribute was ambiguos in the namespace (sort of)

We went back to IronPython 2.0, there we dont have that problem. So I took the copy.py and type.py modules from
the IronPython 2.6 installation and moved them to the app_script folder of an IronPython asp.net project to see if they worked. 

They would seem to be working (the import didnt trigger any error and the copy.deepcopy didnt trigger any error either),
but when we deepcopy a custom class object, the problem we have it's it seems it copies the attributes (that's 
what it shows the object inspector) but not everything in the object. 



When we try to do getattr(object, attribute) we get "  object has no 
attribute 'getitem'" . But the object it's there and it
 has set its attributes. 




Now in the copy module it says 


"This version does not copy types like module, class, function, 
method,
nor stack trace, stack frame, nor file, socket, window, nor array, nor
any similar types."


Does that mean the deepcopy we are making of the object it's not copying 
its methods (methods like getitem ) ? or simply the copy.py and type.py modules dont work well in IronPython 2.0? Or is it something else? 



Greetings, Pablo

Message-ID: <AANLkTinwTMc5Y102iYO4Y0mlfdvJtj8OgEyUQ0hbd8YN@mail.gmail.com>

Hi,

I'm trying to get my head around the IronPython API by implementing a simple
work-around for what I believe is a bug in the next() builtin,which I
reported here: http://ironpython.codeplex.com/workitem/27383.  This is my
first look inside IronPython so this question, I assume, is pretty basic.
How can I handle Python exceptions returned by TryInvokeUnaryOperator?  I'm
currently trying to do this to implement the default value argument in the
next builtin.

        public static object next(CodeContext/*!*/ context, object o) {
            object value;
            if (PythonTypeOps.TryInvokeUnaryOperator(context, o, "next", out
value)) {
                return value;
            }
            throw PythonOps.TypeError("{0} object is not an iterator.",
PythonTypeOps.GetName(o));
        }

        public static object next(CodeContext/*!*/ context, object o, object
defaultVal) {
            object value = next(context, o);
            // This doesn't work.
            if (value is StopIterationException) {
                return defaultVal;
            }
            return value;
        }

Thanks,

Nevermind, I found the problem. It had nothing to do with the module copy not working in IP 2.0, in fact the module copy with IP 2.0  works very well

You can just use a normal try/catch.  IronPython has a mapping between .NET exceptions and Python exceptions.  We actually have documentation on this over here http://ironpython.codeplex.com/wikipage?title=Exception%20Model.  But apparently it's out of date for StopIteration.  For that we now define our own StopIterationException in IronPython.Runtime.Exceptions which you can catch.

For 2.7 we've added support for light exceptions - so if you're downloading the source from CodePlex you'll see some methods are decorated with a [LightThrowing] attribute.  Those methods will return a value which is actual a wrapped exception.  For those you can use the LightExceptions class to see if the return value is a light exception and the code will look more like what you have below.

Subject: [IronPython] Using Epydoc with IronPython 2.6.1
Message-ID: <AANLkTinq0JXkb4w2CoqX_PRnonaPpSHE8RHDBhgqove2@mail.gmail.com>

Hi All,

I am a newbie in IronPython world which by the way rocks. I tried posting
yesterday so I am not sure what happened so sorry if there is a double post.


I am having trouble trying to use epydoc. I have IronPython 2.6.1 for .NET
2.0 on my 32-bit Windows XP box. I am not sure if I have set it up correctly
it is probably me not setting up things correctly.

I installed the epydoc source in c:\python\epydoc and set IRONPATHHOME is
set to C:\python\epydoc\. I am following an example of using epydoc from
their website and added the debug arg to get more information so I cd in
C:\python\epydoc\scripts and executed the following

ipy epydoc.py --html --debug sys -o sys_docs

Traceback (most recent call last):-] Building documentation: sys
  File "epydoc.py", line 16, in <module>
  File "C:\python\epydoc\epydoc\cli.py", line 965, in cli
  File "C:\python\epydoc\epydoc\docbuilder.py", line 454, in
_get_docs_from_pyname
  File "C:\python\epydoc\epydoc\docparser.py", line 209, in parse_docs
  File "C:\python\epydoc\epydoc\docintrospecter.py", line 131, in
introspect_docs
  File "C:\python\epydoc\epydoc\docintrospecter.py", line 275, in
introspect_module
  File "C:\python\epydoc\epydoc\docintrospecter.py", line 131, in
introspect_docs
  File "C:\python\epydoc\epydoc\docintrospecter.py", line 392, in
introspect_class
TypeError: instancemethod.__cmp__(x,y) requires y to be a 'instancemethod',
not a NoneType


I tried find information on using IronPython with epydoc but with no luck. I
got pydoc to work but it pulled documentation for the clr module which I use
of course which took most of the documentation for my module. I thought I
can try epydoc with the parse only feature. I appeciate any feedback.

Thanks

Danny

Hmm... no idea on the specific problem - but this *may* be related:

IronPython 2.6.1:

 >>> class X(object):
...  def f(s): pass
...
 >>>
 >>> a = X()
 >>> a.f.__cmp__
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
AttributeError: 'instancemethod' object has no attribute '__cmp__'

CPython 2.6.5:

 >>> class X(object):
...  def f(s): pass
...
 >>> a = X()
 >>> a.f.__cmp__
<method-wrapper '__cmp__' of instancemethod object at 0x01858DA0>

Hi Michael,

Are there any documentation tools that would work with IronPython that you
would recommend?
I got pydoc to work on a small sample python file but the html documentation
included imports. I had small
python file but the clr module took most of the html documentation. I am
newbie so I could be setting pydoc
incorrectly.
Thanks.

Danny

Hmmm... in terms of automatically generating api documentation from 
docstrings there are embarrassingly few for Python - let alone 
IronPython. Sphinx is great for building documentation but doesn't need 
to be run *with* IronPython and won't pull docstrings from your API for you.

Maybe other people have suggestions.

All the best,

Michael

I looked into the ctypes on mono problem a bit (MONO_LOG_LEVEL=debug mono
ipy.exe is helpful here).  There seem to be three issues:

1) libdl.so is libdl.dylib on OSX and there is no dllmap that does this
automatically on Mono.  It checks for libdl.so.dylib and a few other places
but not libdl.dylib.  This can be fixed by creating a symbolic link or
changing the DLLImport to libdl without the ".so".  Unfortunately the latter
approach breaks breaks linux support.  So I just created this symlink by
hand, which is not ideal.

2) On linux, it seems that RTLD_NOW (2) should be passed to the dlopen call.
(See http://www.mail-archive.com/mono-list at lists.ximian.com/msg30407.html).
 Without this import ctypes works on OSX but not linux, with it things seem
to work on both platforms.

3) LocalAlloc needs a posix equivalent.  I added a calloc(1, size), which
seemed to do the trick.  I'm not expert here, I assume some of the other
public methods should be ported too?

With these changes basic libc calls, like abs(), work on windows, osx, and
linux. Lots stuff doesn't work. Printf gives one character everywhere and
segfaults on linux, but this seems to be the general state of ctypes support
even on Windows.  Unfortunately fcntl through ctypes also doesn't seem to
work, which is why I was looking into ctypes to start with.

Below are my changes to NativeFunctions.cs, which are a partial solution at
best.

Hello,

 

How do I include the NLTK modules in a C# application?

 

There is already code for embedded Python.

 

Thanks.

The first step is to try importing it and running some examples from in 
IronPython. If that works then you just need to provide a 'bridge' layer 
that embeds IronPython in your C# app and allows you to call into 
IronPython to use NLTK.

If NLTK *doesn't* work from IronPython it will probably be because it 
uses C extension modules not available in IronPython. One way round this 
is to use Ironclad. Again, try some NLTK examples from IronPython but 
with Ironclad and see if that works.

If it still doesn't work it may be worth reporting back here with the 
problems to see if they are resolvable.

All the best,

Michael Foord

Hello,


In order for NLTK to work, I need to install PyYaml.


However, the PyYaml installer does not recognize the IronPython installation
in the Registry.


How do I alter the registry?


Thanks.

I don't know - the folks on the pywin32 mailing list could probably tell 
you. An easier route would be to install Python, then install PyYaml, 
then either copy the files to somewhere on sys.path for IronPython (or 
add your Python site-packages folder to sys.path in your IronPython code).

All the best,

Michael Foord

Is there a DBNull value somewhere in your object?  DBNull is a singleton and I'd guess we'd need to add some custom logic which says the way we deserialize it is by pulling the singleton from DBNull.Value.  You can probably use copy_reg.pickle to register something which will handle objects of type DBNull that just returns DBNull.Value.

Hi there,

Im getting this error in the copy module. I moved the copy module from the IronPython 2.6 installation to work with
IronPython 2.0 for some compatibility problem I had with IronPython 2.6 dll with another dll we use.

The only difference I see between the cases which works and those which doesnt are, in the succesful case it is a custom class object "alone", and in the error case is the deepcopy of a custom class object which contains a list with other instances of that object.
Could that have anything to do with the problem? Is that a limitation of the copy module in Python or it should work?

Is there a DBNull value somewhere in your object?  DBNull is a singleton and I?d guess we?d need to add some custom logic which says the way we deserialize
 it is by pulling the singleton from DBNull.Value.  You can probably use copy_reg.pickle to register something which will handle objects of type DBNull that just returns DBNull.Value.

Subject: [IronPython] deepcopy


 

Hi there,


 


Im getting this error in the copy module. I moved the copy module from the IronPython 2.6 installation to work with


IronPython 2.0 for some compatibility problem I had with IronPython 2.6 dll with another dll we use. 


 


The only difference I see between the cases which works and those which doesnt are, in the succesful case it is a custom class object "alone", and in the error case is the
 deepcopy of a custom class object which contains a list with other instances of that object.


Could that have anything to do with the problem? Is that a limitation of the copy module in Python or it should work?


 


error description: 


 

No se puede encontrar el m?todo 'DBNull..ctor'.

Subject: [IronPython] Accessing Iron Python Abstract Syntax Tree

Hi, I am trying to use Iron Python's Compiler to generate an abstract 
syntax tree that I can use, something similar to compile(expr, filename, 
mode, ast.PyCF_ONLY_AST)in CPython. I can't seem to find a compatible 
module in Iron Python, though.

I'm assuming this is possible because I can see that the code is there 
inside Iron Python's source code, but I can't seem to figure out what how 
to access this code from the outside.

I do not want to create my own source code to AST parser, I just want to 
use Iron Python's default parser so I can process some Iron Python code.

Thanks in advance.

Message-ID: <5807998F14A141B4875628B4E795B7A8@NicoPC>

Hi there,

I run python scripts from within a vb.net sollution.
I can add references to our dll's and call all classes, functions, subs etc.  but now I run into a specific problem.
In one of our dll's we have a module 'scriptutills' with a public function 'GetMaxIdentifier'that returns a unique number as a sort of identifier for a new project.  
I can add a reference to the containing dll but when I call scriptutills.'GetMaxIdentifier'() I get an error "'type' object has no attribute 'GetMaxIdentifier'"
If I change the module into a class with the same subs, I c?n call the 'GetMaxIdentifier' function without any problems.  Does anybody has a sollution for this?
Thanks a lot.

Nico

If you start the IronPython console and execute "import sys", then 
"print sys.path" it will show you all the directories it looks when you 
try to import a module.

You can manually add a directory to this path 
("sys.path.append(r'c:\SomePath')") at the start of your code to add 
extra locations to your import path.

All the best,

Michael

I'm afraid there is no subprocess module (yet) for IronPython. Two 
alternatives are:

There's an implementation of the standard library 'ast' module
(http://docs.python.org/library/ast.html) available at
http://bitbucket.org/jdhardy/_ast/.

You'll have to compile it from source, which may mean tweaking the
references in the .csproj file. Let me know if you have any issues (I
really should post some binaries...).

I created a project VbClassLibrary which contains a public module Module1.
The module contains a public function GetMaxIdentifier. From IronPython 2.6,
I say

IronPython 2.6 (2.6.10920.0) on .NET 4.0.30319.1
Type "help", "copyright", "credits" or "license" for more information.
>>> import clr
>>> clr.AddReference('VbClassLibrary')
>>> from VbClassLibrary import Module1
>>> Module1.GetMaxIdentifier
<built-in function GetMaxIdentifier>
>>> Module1.GetMaxIdentifier(2)
4
>>>
So there doesn't seem to be a general problem accessing functions in
VB.NETmodules.

Subject: [IronPython] Convert between python array and .NET Array
Message-ID: <8a6c92fd-2586-4c9d-8beb-eebccf6411ad@40g2000pry.googlegroups.com>

I have a python method that returns a Python byte array.array('c').

Now, I want to copy this array using
System.Runtime.InteropServices.Marshal.Copy. This method however
expects a .NET Array.

import array
from System.Runtime.InteropServices import Marshal

bytes = array.array('c')
bytes.append('a')
bytes.append('b')
bytes.append('c')
Marshal.Copy(bytes, dest, 0, 3)

Is there a way to make this work without copying the data? If not, how
do I convert the data in the Python array to the .NET array?

Thanks,
-- Marcel

This worked for me (based on the code you provided):

import clr
from System import Array

dest = Array[str](bytes)

Subject: [IronPython] Problem Closing Application
Message-ID: <AANLkTinGL35UDEdU8RppfmQzkMfAGJHCyEcpHhLdBBsu@mail.gmail.com>

Hi All

Just to state - I'm a real newbie to programming & ironpython
I have an application that has 2 forms. The application gets started in the
progam.py module(btw i'm using #develop). This calls another module -
login.py. This is a login form which validates user names/passwords. Once
this is validated I *hide* the form and call the second module -
MainForm.py. The program runs fine - except that when I close the MainForm
form - the application is still running. I know it's because a login.py
object is hidden. What I'm asking is how construct the programming in such a
way that this does not happen - that when the second form is closed - the
application closes; or is there a better way to do this?

Regards

Anthony

How about closing the login form instead of hiding it? Another way is to 
handle the Closing event on your main form and close the login form 
then. You can also call Application.Exit()  (I believe - this is off the 
top of my head so you should check) to exit the GUI event loop.

All the best,

Michael

I think I simplified my example a little too far. I'm trying to
display a Bitmap from bytes generated in Python code.

        bytes = array.array('c') # tried 'B' also
        # generate bitmap bytes ...

        bitmap = Bitmap(width, height, PixelFormat.Format24bppRgb)

        bmData = bitmap.LockBits(Rectangle(0, 0, bitmap.Width,
bitmap.Height),
          ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb)

        total_bytes = (bmData.Stride) * bmData.Height

        Marshal.Copy(bytes, 0, bmData.Scan0, total_bytes);

        bitmap.UnlockBits(bmData)

The IronPython exception I'm getting is:
TypeError: expected IntPtr, got array

Casting the bytes array to IntPtr changed the error into:
TypeError: expected int, got array

I'm using IronPython 2.6 (2.6.10920.0) on .NET 2.0.50727.4927

Any idea?

Thanks,
-- Marcel

It looks like the automatic overload resolution may be failing -- at least,
it's worth trying to resolve the overload manually. This would be something
like

from System import Array, Byte, IntPtr
Marshal.Copy.Overloads[Array[Byte], int, IntPtr, int](bytes, 0,
bmData.Scan0, total_bytes)

I'm assuming the problem here is that this is exiting w/ a non-zero exit code indicating something went wrong.  But what went wrong really depends on what the last exception is - there appears to be some failure to import something.  The other exceptions are expected as the standard library throws exceptions on startup.  Can you enable breaking on the import exception (or all exceptions and continue after these) and see what the last exception is?

Subject: [IronPython] Problem with ScriptSource.GetCodeProperties()
Message-ID: <4C155C1E.3040005@voidspace.org.uk>

Hello all,

IronPython 2.6.1:

 >>> import clr
 >>> clr.AddReference('IronPython')
 >>> clr.AddReference('Microsoft.Scripting')
 >>> from IronPython.Hosting import Python
 >>> from Microsoft.Scripting import SourceCodeKind
 >>> engine = Python.CreateEngine()
 >>> scope = engine.CreateScope()
 >>> text = 'lambda'
 >>> source = engine.CreateScriptSourceFromString(text, 'stdin', 
SourceCodeKind.InteractiveCode)
 >>> result = source.GetCodeProperties()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: Value cannot be null.
Parameter name: parameters

If instead of 'stdin' I use '<stdin>' like I used to it throws for that 
as well.

All the best,

Michael Foord

Hi Curt,

Your suggestion gives me:
TypeError: expected Array[Byte], got array

bytes is a Python array. I tried:
Marshal.Copy.Overloads[Array[Byte], int, IntPtr, int]
(bytes.buffer_info()[0], 0, bmData.Scan0, total_bytes)

but that gave the error:
TypeError: expected Array[Byte], got int

This small sample application demonstrates the issue:

import array
import struct
import StringIO

import clr
clr.AddReference("System.Windows.Forms")
clr.AddReference("System.Drawing")

from System import Array, Byte, Char, IntPtr
from System.Windows.Forms import Application, Form, PictureBox
from System.Drawing import Size, Point, Bitmap, Color, Rectangle
from System.Drawing.Imaging import PixelFormat, ImageLockMode
from System.Runtime.InteropServices import Marshal

class IForm(Form):

    def __init__(self):
        bytes = array.array('B')

        width  = 25
        height = 20

        for i in range(width * height):
            bytes.append(i % 256) # R
            bytes.append(i % 256) # G
            bytes.append(i % 256) # B

        bitmap = Bitmap(width, height, PixelFormat.Format24bppRgb)

        bmData = bitmap.LockBits(Rectangle(0, 0, bitmap.Width,
bitmap.Height),
          ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb)

        total_bytes = (bmData.Stride) * bmData.Height

        Marshal.Copy.Overloads[Array[Byte], int, IntPtr, int](
          bytes.buffer_info()[0], 0, bmData.Scan0, total_bytes)
        bitmap.UnlockBits(bmData)

##        for x in range(width):
##            for y in range(height):
##                i = y * width + x
##                bitmap.SetPixel(x, y, Color.FromArgb(bytes[i],
bytes[i+1], bytes[i+2]))

        pb = PictureBox()
        pb.Size = Size(bitmap.Width, bitmap.Height)
        pb.Location = Point(2, 2)
        pb.Image = bitmap
        pb.Parent = self

        self.Size = Size(bitmap.Width + 20, bitmap.Height + 45)
        self.CenterToScreen()

Application.Run(IForm())

Using bitmap.SetPixel works, but I cannot find how to make it work
using the LockBits and Marshal.Copy.

Thanks,
-- Marcel

*RE: Can you enable breaking on the import exception (or all exceptions and

Sorry, I am not familiar how to do this. I search for some tutorial, but if
you have some wiki out there I can use, I can probably give it a try.

Hi Michael

Sorry for the late reply - only got back to my email this morning :-)
I tried to close the form - but when doing that - the whole application
closed - I think this was mainly due to the fact that that form was seen as
the "main form"?? Sorry about this real noob question - but I'm just
starting out - and this is very frustrating for me, I know it's probably
something stupid that I'm doing! Let me post my code here - and see what you
can see!
Here is my code

Subject: [IronPython] Expression and lambda functions
Message-ID: <AANLkTikjFiQFtRV5VeFVhXTkwH4KGhqJJpAGlHHKqSUu@mail.gmail.com>

Hello

I have an c# class with a method taking an expression:
*Refresh(System.Linq.Expressions.Expression<Func<T, bool>> predicate)*

in c# I can call it like;
*Refresh(a => a.ShopArtikel == true);*

is it possible to call the method from python in a similar way? I'm thinking
of
*Refresh(lambda a: a.ShopArtikel == true)*
*
*
how can I convert the lambda function to the expeced expression type?

best,
Severin

I thought closing the whole application was what you wanted to do? In 
your original email you asked:

     The program runs fine - except that when I close the MainForm form 
- the application is still running. I know it's because a login.py 
object is hidden. What I'm asking is how construct the programming in 
such a way that this does not happen - that when the second form is 
closed - the application closes;

So now the application closing is a problem?

All the best,

Michael

Hi

No if I run that code - and I am presented with the MainForm form, when I
hit the close button on the top of the form - the application is still
running in the background. If I try to close the Log_In form
programatically, instead of just hiding it, the whole application closes -
without letting me go the MainForm form.
So not to sure how to accomplish this - have spent quite a lot of time on
the net trying to get the answer - to no avail. Hope that you'll be able to
resolve this issue for me, as I'm stuck in my project, until I can get this
right!

Regards

Anthony

If you run the above code, the main form of the application is Log_In 
form. You have to run application with hidden main form, display log in 
form and after successful log in, display the main form.

By default, the application is closed when the main form of the 
application is closed. If you want different bahavior, see

Ah, I'm clearly not familiar with how the array type was implemented. The
first member of the buffer_info() tuple is an IntPtr, so you probably want
the [IntPtr, int, IntPtr, int] overload of Marshal.Copy. In fact, if you use
the buffer_info() approach, you may be able to avoid manually specifying the
overload. (Though there's something to be said for the types as a form of
documentation -- particularly given the opacity of the call to
buffer_info()).

Personally, my rule of thumb is to use the Python standard library for
portable and "mostly Pythonic" code, but to use .NET types when doing
"mostly .NET". In this case, I think I would have created an Array[Byte]
instead of an array('B') as it's a bit more self-documenting.

It's not currently possible, as far as I know. You should vote for

To just use the IronPython engine in a ASP.NET application, place the DLLs in the same place you would put other 3rd party DLLs; a "bin" directory at the root of the app (same dir as your web.config). See http://aspnet.codeplex.com/wikipage?title=Dynamic%20Language%20Support for direct application framework integration with ASP.NET (code-behind PY files).

There is no support currently for IronPython in ASP.NET MVC, but there is a project that works for IronRuby today, and with minimal work could work for IronPython too: http://github.com/jschementi/ironrubymvc.

Ok, I am sure if what I did was correct.


I did Debug | Exceptions..., since I don't know why exceptions, I just
checked all. Then this is what I got:

Hi Curt,

I did try that overload but I get this quite amusing error message:
TypeError: Copy() takes at least 2147483647 arguments (4 given)

Without the explicit overload selection, I get:
TypeError: expected IntPtr, got int

Did the example work for you with the overload you suggested?

The reason I chose array('B') was twofold. The pixel generation is
done in a pure Python library and I sometimes need to swap the byes
(depending on the endianness of the system), which the Python array
conveniently provides.

Thanks,
-- Marcel

Ok it looks like the last exception is a normal exception from startup.  So the interesting question I guess is what happens between startup and when your script starts?  Can you set a break point on the 1st line of your script and see what happens (you can just hit F9 while on the 1st line of code)?  Does your script successfully run from the command line?

Ok, I am sure if what I did was correct.


I did Debug | Exceptions..., since I don't know why exceptions, I just checked all. Then this is what I got:

I'm assuming the problem here is that this is exiting w/ a non-zero exit code indicating something went wrong.  But what went wrong really depends on what the last exception is - there appears to be some failure to import something.  The other exceptions are expected as the standard library throws exceptions on startup.  Can you enable breaking on the import exception (or all exceptions and continue after these) and see what the last exception is?

Can I make a different recommendation?  Rather than doing a Marshal.Copy
you could use ctypes.memmove.  That would look like:

import ctypes
ctypes.memmove(bmData.Scan0, bytes.buffer_info()[0], total_bytes)

If Scan0 is actually an IntPtr youa may need to do a .ToInt32() or .ToInt64()
on it (I don't remember if we support IntPtr's when marshalling to ctypes - 
we probably should).

Even better still would be to use a ctypes array:

bytes_type = (ctypes.c_int8* total_bytes)
bytes = bytes_type()
ctypes.memmove(0, bytes, total_bytes)

Thanks Dino, the ctypes.memmove does work!

I wasn't aware that ctypes could be used in IronPython. Do they
marshal to unmanaged code under the hood?

Let me know if you want me to file a bug against the Marshal.Copy
overload behavior.

Thanks,

There's not really any unmanaged code on *our* side involved at all.  It
all turns into .NET's support for interop.  So we'll generate calli calls
w/ the correct signature.  And then all the memory access we do is through
the Marshal APIs.  I actually didn't even need to flip the /unsafe compiler
flag in order to implement it all :)

I actually don't think this is a bug.  The problem here is that you either
have a pointer (as an int but it could trivially be turned into an IntPtr) or 
an IronPython array object and then an IntPtr.  For the 2 IntPtr cases there's
no overloads on Marshal and I don't believe anywhere in .NET.  For ctypes to
implement memmove we had to P/Invoke.  And for the array case you don't have
a .NET array.

If we exposed the underlying .NET array then you could use Marshal.Copy.  But 
I'm reluctant to do that because we might want to switch to allocating 
unmanaged memory for the array in the future.  That'll work better w/ ctypes 
and calls to buffer_info() - currently need to pin the array for 
an unknown amount of time.  That's another reason to allocate the memory via
ctypes.

Yes, this is my mistake. I think I saw the [IntPtr[], int, IntPtr,
int] overload and mentally elided the first array specifier.

Hi Dino,

Thanks for being patient. I think you are right. It is actually working, I
am just not used to seeing "expected" exceptions.

By the way, where can I find ipy.pdb (I am assuming that it is the file that
"Cannot find or open the PDB file" points to as shown in debug session)?

Regards,
Yngipy

Hi All,

I have tried to transliterate the following C# code to IronPython:

using System.Collections.Generic;
using System.Linq;

        {
            AutomationElement eNode;
            eNode =
TreeWalker.ControlViewWalker.GetFirstChild(AutomationElement.RootElement);
            while(eNode != null) {
                if (eNode.Current.Name == "Untitled - Notepad")
                {
                    AutomationElement ae;
                    ae = TreeWalker.ControlViewWalker.GetFirstChild(eNode);
                    System.Console.WriteLine("-------------------");
                    while (ae != null)
                    {
                        System.Console.WriteLine("Name: {0}",
ae.Current.Name);
                        ae = TreeWalker.ControlViewWalker.GetNextSibling(
ae);
                    }
                    System.Console.WriteLine("-------------------");
                }
                eNode = TreeWalker.ControlViewWalker.GetNextSibling(eNode);
            }
        }
    }
}

The output of this program looks like:

-------------------
Name: test1
Name: Untitled - Notepad
Name: Application
-------------------

This is my IronPython code:

import clr

clr.AddReference('UIAutomationTypes')
clr.AddReference('UIAutomationProvider')
clr.AddReference('UIAutomationClient')

import System.Windows.Automation as swu

rae = swu.TreeWalker.ControlViewWalker.GetFirstChild(
swu.AutomationElement.RootElement )
while rae:
    if rae.Current.Name == 'Untitled - Notepad':
        print '-'*24
        ae = swu.TreeWalker.ControlViewWalker.GetFirstChild( rae )
        while ae:
            print ae.Current.Name
            ae = swu.TreeWalker.ControlViewWalker.GetNextSibling( ae )
        print '-'*24
    rae = swu.TreeWalker.ControlViewWalker.GetNextSibling( rae )

The output of this shows:
------------------------
test1
------------------------

I read somewhere that IronPython used to have issues with UI Automation. Is
still the case?

Subject: [IronPython] UI Automation: Wrong values for ControlType,
	AutomationElementID and more. IronPython 2.6.1
Message-ID: <279FB2C5A55A4A4DBAD10C001903701C07BAB807@server-b.kratzer.lan>

Hello to all,
 
over many years I have forced to implement a test automation scenerie in
our company.
Now they will do it and - who hat thougth that - I've got the job! And I
had to bring the job to success!
 
My Environment:
------------------------
I've succesfully presented a test automation solution only build from
Internet-Software. It includes:
 
Keyword-Driven Tables in HTML (done with Winword)
                                  !
                           Python 2.6
                                  !
                      Robot-Framework
                       !                      !
             ApplTestlib.py    SeleniumLibrary
                      !                         !
              pyWinAuto       WEB-AppToTest
                      !
         WIN32-AppToTest
 
Later we will embed the solution in a QAtrac process.
 
Now it's time to test automate GUIs build from Windows-Forms and WPF
too.
 
First I switched Python 2.6 to IronPython 2.6[and 2.6.1 RC1] and got
only one, but 'very magic', bug in Robot-Framework when creating the
HTML-Report-File.
Second I'm switched the pyWinAuto-Layer to Miscrosoft UI Automation
(.NET >= 3.0) to support all GUI-Frameworks (WIN32, WINFORMS and WPF)
 
I. In IronPython all UI Automation values ControlTypePropertys (w/o the
window itself) where Type 'panel'.  Other values are also not the same
as you can see
with UISpy or UIA Verify (Tool from Codeplex 'white'-Project). The
AutomationIDs has the values from NativeWindowHandles (unique - but
never the same from run to run!).
Only the NamePropertys are OK but often empty (when control has no text
content yet).
 
II. All Controls in the window title (titlebar, menubar, menuitems, and
min-, max- and close-Button) where completely hidden in Automation-Tree
(I've tested with Raw-, Control- and ContentViews)! These eight controls
are from IronPython-UI Automation not reachable. This may be a
consequence from point I. above.
 
In this situation it's unpossible for me to identify Controls in the
application to automate!
 
I have found, I run in exactly the same problems witch where reported
from Jozef in November 2009:
http://lists.ironpython.com/pipermail/users-ironpython.com/2009-November
/011583.html
 
and heself stated a own solution in
http://lists.ironpython.com/pipermail/users-ironpython.com/2009-November
/011630.html
 
The solution reads:
 
'Thanks for your response.
Solution to my problem is to first instantiate AutomationElement from
dll, not from IronPython.
Then all subsequent AutomationElement retrieved from IronPython looks
ok.'
 
About 30 years I have programmed in ANSI-C (Same SW on Windows,VMS,
Linux, etc.) but now being a newbie to C#, .NET and Python.
 
Therefore I should have an (syntax-)example for the expression:
    'to first instantiate AutomationElement from dll'
 
Witch DLL (Own written, .NET-DLL. ??)
How to instantiate in C#?
How to transport the AutomationElement to IronPython?
 
The best will be if jozef.a... will give me some example lines of code
from his solution in nov 2009 in C# and/or Python. Thanks.
 
Greetings
Wolfram

I was able to successfully run that python code under both IronPython 2.0.3 and IronPython 2.6.1 and it produced a list of all top-level applications.  I modified the one line

if rae.Current.Name == 'Untitled - Notepad':

to be

if not rae.Current.Name == '':

just to see what was actually being found.

Note: I'm running Windows XP SP3.

Hi All,

I have tried to transliterate the following C# code to IronPython:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Automation;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            AutomationElement eNode;
            eNode = TreeWalker.ControlViewWalker.GetFirstChild(AutomationElement.RootElement);
            while(eNode != null) {
                if (eNode.Current.Name<http://eNode.Current.Name> == "Untitled - Notepad")
                {
                    AutomationElement ae;
                    ae = TreeWalker.ControlViewWalker.GetFirstChild(eNode);
                    System.Console.WriteLine("-------------------");
                    while (ae != null)
                    {
                        System.Console.WriteLine("Name: {0}", ae.Current.Name<http://ae.Current.Name>);
                        ae = TreeWalker.ControlViewWalker.GetNextSibling( ae);
                    }
                    System.Console.WriteLine("-------------------");
                }
                eNode = TreeWalker.ControlViewWalker.GetNextSibling(eNode);
            }
        }
    }
}

The output of this program looks like:

-------------------
Name: test1
Name: Untitled - Notepad
Name: Application
-------------------

This is my IronPython code:

import clr

clr.AddReference('UIAutomationTypes')
clr.AddReference('UIAutomationProvider')
clr.AddReference('UIAutomationClient')

import System.Windows.Automation as swu

rae = swu.TreeWalker.ControlViewWalker.GetFirstChild( swu.AutomationElement.RootElement )
while rae:
    if rae.Current.Name<http://rae.Current.Name> == 'Untitled - Notepad':
        print '-'*24
        ae = swu.TreeWalker.ControlViewWalker.GetFirstChild( rae )
        while ae:
            print ae.Current.Name<http://ae.Current.Name>
            ae = swu.TreeWalker.ControlViewWalker.GetNextSibling( ae )
        print '-'*24
    rae = swu.TreeWalker.ControlViewWalker.GetNextSibling( rae )

The output of this shows:
------------------------
test1
------------------------

I read somewhere that IronPython used to have issues with UI Automation. Is still the case?

We haven't been posting our PDBs but ipy.pdb isn't very useful - ipy.exe is just a stub which kicks off the process.  I think we should probably start posting them for future releases (although they may be available via the public MS symbol servers - I'm not sure if they automatically get deployed when we save them).

Hi Dino,

Thanks for being patient. I think you are right. It is actually working, I am just not used to seeing "expected" exceptions.

By the way, where can I find ipy.pdb (I am assuming that it is the file that "Cannot find or open the PDB file" points to as shown in debug session)?

Ok it looks like the last exception is a normal exception from startup.  So the interesting question I guess is what happens between startup and when your script starts?  Can you set a break point on the 1st line of your script and see what happens (you can just hit F9 while on the 1st line of code)?  Does your script successfully run from the command line?

Sorry, I am not familiar how to do this. I search for some tutorial, but if you have some wiki out there I can use, I can probably give it a try.

I'm assuming the problem here is that this is exiting w/ a non-zero exit code indicating something went wrong.  But what went wrong really depends on what the last exception is - there appears to be some failure to import something.  The other exceptions are expected as the standard library throws exceptions on startup.  Can you enable breaking on the import exception (or all exceptions and continue after these) and see what the last exception is?

But not when trying to iterate child elements of the Notepad automation
element.

I have been playing around UI Automation and IronPython for several days

I am trying to dig deeper to understand why.....

Probably this issue is not fixed yet?

Hello all,
 
unless we get following child elements for example in a empty notepad application all playing be be useless:
 
Raw View:
---------------
  "Window" "Unbenannt - Editor"
    "Document" ""
      "Scrollbar" "Vertikale Bildlaufleiste"
        "Button" "Zur?ck um kleine Menge"
        "Button" "Vorw?rts um kleine Menge"
    "Titelbar" "Unbenannt - Editor"
      "Menubar" "Systemmen?leiste"
        "Menuitem" "System"
      "Button" "Minimieren"
      "Button" "Maximieren"
      "Button" "Schlie?en"
    "Menubar" "Anwendung"
      "Menuitem" "Datei"
      "Menuitem" "Bearbeiten"
      "Menuitem" "Format"
      "Menuitem" "Ansicht"
      "Menuitem" "?"

It a german window a I have translated the ControlType (1st word; 2nd = name) to english.
 
The output ist created from the tool UISpy, witch shows all AutomationElements from all application curently running as child beneath the 'desktop' window.
 
UISpy come from MS and can be downloaded free.
 
Greetings
Wolfram

I tried your IronPython script and it found one child element which name is ''.

Change the print line to:
print 'Name:',  ae.Current.Name

		Hi All,

		 

		I have tried to transliterate the following C# code to IronPython:

		 

		using System;

		using System.Collections.Generic;

		using System.Linq;

		using System.Text;

		using System.Windows.Automation;

		 

		namespace ConsoleApplication1

		{

		    class Program

		    {

		        static void Main(string[] args)

		        {

		            AutomationElement eNode;

		            eNode = TreeWalker.ControlViewWalker.GetFirstChild(AutomationElement.RootElement);

		            while(eNode != null) {

		                if (eNode.Current.Name == "Untitled - Notepad")

		                {

		                    AutomationElement ae;

		                    ae = TreeWalker.ControlViewWalker.GetFirstChild(eNode);

		                    System.Console.WriteLine("-------------------");

		                    while (ae != null)

		                    {

		                        System.Console.WriteLine("Name: {0}", ae.Current.Name);

		                        ae = TreeWalker.ControlViewWalker.GetNextSibling( ae);

		                    }

		                    System.Console.WriteLine("-------------------");

		                }

		                eNode = TreeWalker.ControlViewWalker.GetNextSibling(eNode);

		            }

		        }

		    }

		}

		 

		The output of this program looks like:

		 

		-------------------

		Name: test1

		Name: Untitled - Notepad

		Name: Application

		-------------------

		 

		This is my IronPython code:

		 

		import clr

		 

		clr.AddReference('UIAutomationTypes')

		clr.AddReference('UIAutomationProvider')

		clr.AddReference('UIAutomationClient')

		 

		import System.Windows.Automation as swu

		 

		rae = swu.TreeWalker.ControlViewWalker.GetFirstChild( swu.AutomationElement.RootElement )

		while rae:

		    if rae.Current.Name == 'Untitled - Notepad':

		        print '-'*24

		        ae = swu.TreeWalker.ControlViewWalker.GetFirstChild( rae )

		        while ae:

		            print ae.Current.Name

		            ae = swu.TreeWalker.ControlViewWalker.GetNextSibling( ae )

		        print '-'*24

		    rae = swu.TreeWalker.ControlViewWalker.GetNextSibling( rae )

		 

		The output of this shows:

		------------------------

		test1

		------------------------

		 

		I read somewhere that IronPython used to have issues with UI Automation. Is still the case?

First off, Notepad was running with the word "test1". Sorry for not being
clear.

As with Wolfram, I also used UI Spy. UI Spy would see tree element from the
"Notepad" window. Namely:
Edit control (this contains "test1" text)
TitlebarControrl (this is where the min, max, close, system menu is
contained. And it has the text "Untitled - Notepad")
Application Menu bar (This is the main menus).

So yes, IronPython does not seem to like UI Automation much. C# can do it
just fine by the way.

This might be related to this
issue<http://blogs.msdn.com/b/shrib/archive/2008/03/24/ironpython-cannot-call-automationelement-fromhandle.aspx>.
I am hoping that people with deep enough knowledge about IronPython can
confirm this.

Or if I can get enough direction, I can spend some time digging into it....
but I need hint how to go from here.

Regards,
Yngipy

Just an idea - create a proxy in C# that calls 
TreeWalker.ControlViewWalker.GetFirstChild and other methods for you and 
return you the results. Maybe it will work. The similar way I created 
the C# proxy to access Win32API functions 
(http://gui-at.blogspot.com/2008/07/simulate-users-input.html)

Subject: [IronPython] ElementTree bug?
Message-ID: <AANLkTinfSQSYZV7fbCHsV-rpaiHGR2J6RX4NY_j4MDXG@mail.gmail.com>

Hi everyone,
There seems to be an inconsistency in the ElementTree class between CPython
and IronPython.

In CPython 2.6.4:

*Python 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit
(Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import xml.etree.ElementTree as etree
>>> xml_str = "<Message><User>David</User><Phone>123-4567</Phone></Message>"
>>> xml = etree.XML(xml_str)
>>> print xml.find("Phone").text
123-4567
>>>
*

In IronPython 2.6.1:

*IronPython 2.6.1 (2.6.10920.0) on .NET 2.0.50727.3603
Type "help", "copyright", "credits" or "license" for more information.
>>> import xml.etree.ElementTree as etree
>>> xml_str = "<Message><User>David</User><Phone>123-4567</Phone></Message>"
>>> xml = etree.XML(xml_str)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files\IronPython 2.6\Lib\xml\etree\ElementTree.py", line
962,
 in XML
  File "C:\Program Files\IronPython 2.6\Lib\xml\etree\ElementTree.py", line
1117
, in __init__
ImportError: No module named expat; use SimpleXMLTreeBuilder instead
>>> xml = etree.fromstring(xml_str)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files\IronPython 2.6\Lib\xml\etree\ElementTree.py", line

  File "C:\Program Files\IronPython 2.6\Lib\xml\etree\ElementTree.py", line
1117
, in __init__
ImportError: No module named expat; use SimpleXMLTreeBuilder instead
>>>
*

So both XML and fromstring fail to parse the xml string. Is this a bug?

Haha -- yeah, the cpython one works.  The problem seems to be that
there's no expat module available to IronPython.

The traceback message says to try SimpleXMLTreeBuilder, but I couldn't
import that one successfully either.

This is what I am doing currently. But I wished I can do all the fun in
IronPython without using C#.

So is this a known bug, or is expat one of the C-based extension modules
that IronPython doesn't handle yet?

expat is one of C-based extension modules that IronPython doesn't handle yet.

On the other hand, here is my implementation that works with ElementTree:
https://fepy.svn.sourceforge.net/svnroot/fepy/trunk/lib/pyexpat.py

Put it on any sys.path directory.

Ok, I have a sample project how to use UI Automation with IronPython, see :
http://pyas.svn.sourceforge.net/viewvc/pyas/trunk/src/ipr/

<http://pyas.svn.sourceforge.net/viewvc/pyas/trunk/src/ipr/>Basically, I
have to :
Create a really simple DLL using C# that reports the root element. That's
it.

Subject: [IronPython] Modules in hosted enviroment
Message-ID: <D4996212B5DB46B8AE8BFD602CC512C1@RossDesktop>

I have a project where I am hosting IronPython and I was wondering what is the best way to create modules in C# for python to use. I have found two ways to do it so far. One method is what is done in IronPython, where static classes and the PythonModule attribute are used but I don't want to use static classes to access runtime data. The other method I found was to use the module class and add all my functions, sub-modules and other data to the dictionary but this is painful to setup and I don't know how to over load functions I add to the dictionary.

Is there another method I can use to create modules or am I over looking something in one of the methods I found?
Thanks for the help

Fixes a stack overflow on 64-bit w/ deeply nested conditionals.  When we have a large conditional we now generate 

If cond0:
                Body
                Goto end
If cond1:
                Body
                Goto end

else_body
end:

instead of:

if cond0:
                body
else:
                if cond1:
                                body
                else:
                                else_body

That keeps the conditional flat so we don?t stack overflow.  We still generate the old way for small conditionls because it?s simpler to construct.

I'm not 100% sure what you mean here, but the static class is just a
container - and it can contain non-static classes (and functions, and
static variables, etc). If it needs to be a module, it's the way to
go, as far as I'm concerned. If things get too big, don't forget that
you can use partial classes to split things up.

However, depending on what your code does, you probably don't need to
make it a module - IronPython will work just fine with any .NET class
library. Just do a `clr.AddReference` and then import the classes.

My program creates data for a python script to use and I though the best way 
for it get access to this was with modules. Simply setting a variable in the 
script would not work because of the complexity of the data. Using the clr 
module will not get access to the existing data (I also do not want to grant 
access to all the other libraries). So I am left with creating a module but 
using a static class and assigning all the instances to the static classes 
every time before I call the python script is not a great method but I'm 
thinking this would be the best at this point. The other method I found was 
using the IronPython.Runtime.PythonModule class and Creating an instance for 
each of my modules and adding to using 
PythonEngine.Runtime.Globals.SetVariable The procedure to do this doesn't 
give the impression that what I'm doing was ever intended and I have hit 
things that I cannot do using this method. So I'm looking for a good method 
of creating modules that would have my data attached to them.

Thanks
Ross

Hi Ross,
Sorry if I'm being dense, but here's how I understand what you're doing:

- you're hosting IronPython in some program X
- X will generate data D and somehow feed D to Python script Y
- Y will transform or process D in some way

What you're looking for is the best way to get D into Y, correct?

I think creating a module is the wrong way to go about this; modules
are supposed to contain code and constant data, as the IronPython
engine will only load them once and share them.

Why is setting a variable for the Python script to use not suitable?
If it needs to be a complex object, you can create a (non-static)
class in C#, fill it out, and pass an instance to the Python script
using ScriptScope.SetVariable.

- Jeff

Alternately you could implement IAttributesCollection and execute the
Python code against a scope which is backed by the IAC.  This would
let you lazily provide the values to the script on-demand.  If you have
a fixed set of members I like Jeff's suggestion more but this is good if
the members are being generated dynamically.

Subject: [IronPython] -X:PassExceptions
Message-ID: <4C20EDE3.20405@gmx.ch>

Hi all

In order to see the full stack traces, I'd like to have 
-X:PassExceptions set for all my scripts.

Is there a way to set this from *inside* a running script?

Thanks
Kuno

    You are correct about what I'm trying to do, sorry if wrote it in a way 
that was hard to understand. The project I'm working on this for is a 2-D 
game engine. I plan on calling python functions from C# with the relevant 
class (say on a collision with the colliding objects as parameters) but if 
extra data is needed about other items it can retrieve the list of them and 
these python function will need to execute quickly.
    With modules I can make different ways to access the wrapper classes I 
have made because in have the internal structure and can retrieve smaller 
sets based off whet the script calls and it won't need to pick through it or 
if it does the set would not be as big.
    I also want to maintain backwards compatibility as I add more 
functionality and if I set variables I worried about a script already using 
the variable and I use one class it would probably have a very large 
hierarchy or lots of unrelated functions which I want to avoid  passing into 
python.

An unrelated issue I have with ScriptScope is I can't figure out to add 
overloaded functions with different parameter counts for defaults I'm using 
3.5 if it matters.

Thanks
Ross

Subject: [IronPython] TryGetMember is called for methods instead of
	TryInvokeMember
Message-ID: <AANLkTikig2xI0FQne3pcrlxyKSrk_MEAfso9sRgknF8u@mail.gmail.com>

I have an application that passes a DynamicObject to an IronPython script.
The class works perfectly in C# but when a method is invoked inside a
IronPython script the TryGetMember is called instead of TryInvokeMember and
if I try to return a value through TryGetMember I get an exception saying
that the member is not callable.

I found a user with similar problem (
http://social.msdn.microsoft.com/Forums/en/dlr/thread/0556e593-2360-43b8-97e5-201c3c3ce1c5).
He said that dowloading the latest release solved the problem. I have
downloaded the latest source code release (70538), compiled it to .NET 4.0,
but I still having the issue.

Here is a slightly modified code I get from the post, that does not work for
me:


using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using IronPython.Hosting;

using IronPython.Runtime;

using Microsoft.Scripting;

using Microsoft.Scripting.Hosting;

using System.Dynamic;

   namespace TestDynamicInvokeFromPython

{

class Program

{

static void Main(string[] args)

{

dynamic myDynamicObject = new MyDynamicObject();

//first tey calling this object from C#, it should call Foo() and they try
to call MissingMethod();

Console.WriteLine("C# Test...");

try

{

myDynamicObject.Foo();

System.Console.WriteLine("Method Result: " +
myDynamicObject.MissingMethod());

}

catch (Exception ex)

{

Console.WriteLine("Got C# exception: " + ex.Message);

}

 ScriptEngine pythonEngine = Python.CreateEngine();

ScriptScope scriptScope = pythonEngine.CreateScope();

string pythonScript = SetPythonScript();

ScriptSource script =
pythonEngine.CreateScriptSourceFromString(pythonScript, SourceCodeKind
.Statements);

scriptScope.SetVariable("myDynamicObject", myDynamicObject);

//Now do the same thing from python, I expect to get the same behaviour as
from C# (but I don't)

Console.WriteLine("\r\nScript Test...");

try

{

script.Execute(scriptScope);

}

catch (Exception ex)

{

Console.WriteLine("Got script exception: " + ex.Message);

}

 Console.ReadKey();

}

static string SetPythonScript()

{

string s = "";

s += "import clr" + "\r\n";

s += "clr.AddReference('mscorlib')" + "\r\n";

s += "myDynamicObject.Foo();" + "\r\n";

s += "myDynamicObject.MissingMethod();" + "\r\n";

return s;

}

}

 public class MyDynamicObject : DynamicObject

{

public void Foo()

{

Console.WriteLine("Foo() Called");

}

public override DynamicMetaObject GetMetaObject(System.Linq.Expressions.
Expression parameter)

{

Console.WriteLine("GetMetaObject() Called");

return base.GetMetaObject(parameter);

}

public override bool TryInvokeMember(InvokeMemberBinder binder, object[]
args, out object result)

{

if (binder.Name == "MissingMethod")

{

result = "Method Found";

return true;

}

else

{

result = null;

return false;

}

}

public override bool TryGetMember(GetMemberBinder binder, out object result)

{

Console.WriteLine("TryGetMember() Called");

return base.TryGetMember(binder, out result);

}

//#region AllOtherOverridees

}

}

Subject: [IronPython] changes in COM access from IronPython 1.1
Message-ID: <4C210495.6040702@fibertel.com.ar>

hi all,
     we have a problem with a project after updating it to IPy 2.6.1. We 
need to use a COM library; we add the reference in VS which creates the 
interop.XXX file. In IPy v1.1 we could access the imported types 
directly, like

LN_AclEntry = LN_dbACL.GetEntry(entryName)

if (LN_AclEntry == None):
   DebugMessage("%s entry does not exist in database: %s" %(entryName, 
databaseName))
else:
   if (LN_AclEntry.Level >= ACLLEVEL.ACLLEVEL_DESIGNER):
     ...

the important line here is the last one: in IPy 1.1, LN_AclEntry is an 
instance of LN_AclEntry {Domino.NotesACLEntryClass}. In IPy 2.6.1, this 
same variable is of type LN_AclEntry {System.__ComObject}.

This means we can't access Level property and compare with ACLLEVEL 
enumeration.

Is there something we can do to get v1.1 behaviour back? If not, can we 
cast somehow the object to the correct type?

Thanks in advance,

Ernesto Cullen

You probably want to use ScriptEngine.SetSearchPaths. It's equivalent
to setting sys.path.

Mr. Hardy:

Thanks for your input.

However, I am having difficulties finding your zlib dll from the DLLs
directory.

Could you also assist me on this?

I assume this is from a hosting application, correct?

All you'll need to do is load the assembly from disk, and then load it
into the engine:

    Assembly zlib = Assembly.LoadFile(@"path\to\IronPython.Zlib.dll");
    engine.Runtime.LoadAssembly(zlib);

Your hosted IronPython scripts should now be able to import zlib.

The IronPython console gets all of the .dll files in the DLLs folder,
loads them, and calls .LoadAssembly if the load succeeds. If you have
many dlls to load, or you want users to be able to add them, you'll
need to duplicate that part for your hosting application.

Hi Ross,
It sounds like you want Dino's suggestion IAttributesCollection, which
will give you much more flexibility. I've never done that, but it
looks fairly straightforward.

I assume what you have here is a bunch of static methods declared somewhere and
you want to publish them in the scope?  The only way to really go about doing
this is getting the BuiltinFunction object for them and then publishing that
in the scope.  To get the BF you'll need to first get the PythonType and then
get the BF.  Such as:

public class MyObjectModel {
	public static void Foo() {
	}

	public static void Foo(object x) {
	}
}

Using C# 4.0 then I think you could do:

dynamic foos = ((dynamic)DynamicHelpers.GetPythonTypeFromType(typeof(MyObjectModel))).Foo;

or you could do:

object foos = engine.Operations.GetMember(DynamicHelpers.GetPythonTypeFromType(typeof(MyObjectModel))), "Foo");

Calling TryGetMember is actually the correct thing to do.  Different languages have different semantics for when you do ?a.Foo();?  Some languages turn this into an InvokeMember while other languages separate this out into a get and invoke.  In Python we separate this out into a get and invoke but you could also get this behavior in C# by doing:

dynamic x = a.Foo;
x();

Which should also work.  So you really need to support both GetMember and InvokeMember.  The result of the GetMember is usually something which binds the instance to the member and then when it does whatever InvokeMember would have done.

I believe the part about updating to the latest assemblies in the thread was about using the assemblies compiled for .NET 4.0 instead of the assemblies compiled for .NET 2.0 SP1+ which don?t work w/ dynamic in .NET 4.0.

Hi All,

How would I know if _getframe is supported in sys module? From the
blogosphere, you need to type -X:FullFrames to enable _getframe but I would
like to detect if this is available or not in ipy script.

Regards,

Ok, I think I found it:
import sys
if hasattr(sys,'_getframe'):
  print "yes"

You are correct, but this has already been reported and is fixed on 
trunk. The fix will be in 2.6.2 which will hopefully be released soon... :-)

All the best,

This is almost what I want but I to pass and instance of a class(no static 
methods) and have python treat it as if it were static method. After 
re-evaluating what I want I can see why it might not be possible. So if it 
ends up that I can't do what I described I will use on of the many other 
methods indicated.

Thanks for the help

Are you trying to get rid of the "foo.Bar" or do you want the user to
be typing something like "MyObjectModel.Bar"?  Or are you just wanting the
user to type "Bar"?  You can just pass the instance of the class in and the 
user can dot through it and call methods on it - as far as they're concerned 
there's not much of a difference between static vs. instance - it's either 
dotting through the class name or the instance name.  

If you really want the user to just type "Bar" the good news is that you'll 
be able to do it in a future version.  You'll just need to subclass 
DynamicObject and put a dictionary in it for storing additional attributes.
Then you can add your methods to it and pass it as the storage for a scope.
You can also override TryGetMember and then do the lazy lookup of attributes
as well.

Unfortunately it doesn't work right now in 2.6 due to a bug in IronPython (you
get an exception saying __doc__ is readonly). It is fixed in the 2.7 branch 
though and I can look at backporting it to 2.6.x.  This is the way we really want
things to work going forward though - scopes are just dynamic objects.  That
will enable you to have thinks like static properties or fields which languages
can bind to very tightly and get really high performance global variable 
lookups.

I'm not following what you are saying there. I figure the easiest way for me 
to show what I want to do was give an example. The example shows everything 
I would like to do ignoring exceptions. The function returned from call 
python would be executed when certain events occurred in the program.

The user script is what I would like to have and what I have to do to 
achieve this in C# doesn't really matter but if it could be as simple as 
what I have below it would be nice. I have gotten this to work right now by 
creating and filling out IronPython.Runtime.PythonModule 's dictionary to 
match the definition of each class then assigning it to the engine's 
globals. Even though I have it mostly working it is very unpleasant to deal 
with because I need to fill out everything the dictionary needs and I can't 
overload functions(thanks previous help from here I may be able to resolve 
this now). The code below will work right now if instead I set app to a 
variable in the script instead of a global but I would greatly prefer it to 
use imports.

C# application
class Program
{
                // Other stuff here for program

	Action CallPython()
	{
		App app = new App(this);
		var engine = Python.CreateEngine();
		engine.Runtime.Globals.SetVariable("app", app);
		var scope = engine.CreateScope();
		// execute python script....
		return scope.GetVariable<Action>("event");
	}
}

class Wrapper
{
	public int value { get; set; }
	public Wrapper(int i) { value = i; }
}

class Data
{
	internal Data() { }
	public PythonType Class { get { return 
DynamicHelpers.GetPythonType(typeof(Wrapper)); } }
	public readonly int CONST = 5;
}

class App
{
	private Data _data = new Data();
	private Program _mainApp;

	internal App(object mainApp) { _mainApp = mainApp; }

	public int func() { return _mainApp.Offset; }
	public int func(int i) { return i - _mainApp.Offset; }
	public void action(Wrapper w) { _mainApp.AddItem(w.value); }
	public Data bar { get { return _data; } }
}

user script (python)
from app import func, action
from app.data import CONST, Class

i = func(20)
c = Class(CONST)
c.value = i

def event(a = 5):
    action(c)


Thanks

IronPython Readme:
- we're no longer 2 times faster than CPython at PyStone.  Only 37% with 2.6.1, although we did make massive improvements in PyBench and other benchmarks
- it's been more than several years since .NET was standardized in ECMA
- prefer IronPython.net over codeplex.com/IronPython now as IP's information site
- NOTE: http://www.codeplex.com/wikipage?ProjectName=IronPython&title=Differences was never updated for IronPython 2.6 and we need something here for 2.7 in the future
- .NET 4.0 is required for 2.7, not .NET 2.0 SP1
- sample ipy.exe interaction session output was incorrect for both 2.6 and 2.7.  Updated
- updated statement about what IronPython.sln generates in terms of assemblies.  Specifically, I've removed dead assemblies and clarified that the list of assemblies is a subset of what's actually generated

Removed all traces of IronPython4.sln.  On that note, IronPython.sln is now a copy of the last version of IronPython4.sln.

Removed CodePlex-DLR-Dev10.sln and CodePlex-DLR-VSExpress.sln.  These serve no purpose now that CodePlex-DLR.sln can build both .NET 2.0 SP1 and .NET 4.0 variants of ipy.exe+ir.exe using different build configurations.

So does this mean there won't be a version of 2.7 for .NET 2.0? Fine
by me - supporting both for 2.6 is a pain.

But I think we do intend to ensure that we still build on .NET 3.5
and above - we just won't be releasing those binaries ourselves.  .NET 2.0
SP1 will be dropped completely and we won't be doing our normal 
extensive test passes on .NET 3.5.

Message-ID: <AANLkTikiVnLqQdI6oxJ4WQ76XV4FyaC1G06N1_tlaBY4@mail.gmail.com>

I have been trying to hire somebody to implement the greenlet extension
module, which would enable modules like eventlet and gevent to work on
IronPython.  The person I currently have looking into it, however, isn't
hopeful. A condensed version of his perspective is below.  Perhaps the
IronPython list (Dino?) has an idea for a solution?

== Response to Greenlets on IronPython ==

I looked at various solutions but none of them seem to arrive at the correct
solution. I did try generating the DLR using AST again to make the function
stackless but the limitation is with python and .NET.

Let me explain the issue.

1) .NET lanugages (C#. VB.NET etc.) are strongly typed. In other words, if I
get a variable I know what its type is at compile time. IronPython actually
compiles the functions into CLR and runs them on the fly. A function is
compiled once and can be executed again and again. One must know that the
function needs to be stackless at compile time and a function cannot be made
stackless at run time.

2) Python is a typeless language. A variable can assume any type at any
point in execution at run-time. Now consider the following code in Python
using the greenlet API:

a = greenlet(foo)

def abc():
    print "X"
    a.switch()
    print "Y"

Although variable a is defined, it does not have a strong type and during
execution, a can be assigned a different object which can also implement the
switch function and the code will execute fine.

As mentioned above, IronPython needs to know at compile time that the
function has to be made stackless. In python since a is not typed, a can be
greenlet in one execution of abc and any other object in the second call.
Also, there is no way to determine at compile that the function abc needs to
be made stackless since it needs to switch since the type of a is unknown
till it is actually called at runtime.

Hence is it next to impossible to implement the switch because of the above
implementation.

CPython dos not compile the functions and does not use the yield keyword
(which is not avilable in C/C++ anyways) to do it. It does this by
using context switching which is built into python and so the API is
fairly straightforward in CPython. CPython basically has the stack of all
previous functions calls and saves the stack so that it can resume later
from that point. It needs to store the context and uses the inherent context
switching built into Python to do it.

== End Response ==

Ideas?

Some updates to the IronPython tutorial making it release-ready for IronPython 2.7 Alpha 1.  We still need a comprehensive review of this doc after the final Beta ships.

IronPython Tutorial:
- .NET 4.0 is now the min bar for running IronPython 2.7
- VS 2010 is required to build IronPython 2.7
- ripped out "Merlin the Wizard" COM interop section.  Not available under Win7 and we already have a COM interop section on Word
- replaced the "there's no VS support for IronPython" blurb with a link to the IronPython Tools download page
- we still had a reference to VS 2005?!?  Removed
- updated some ipy.exe interactive session?s output
- replaced references to CPython 2.6 with CPython 2.7

Message-ID: <4C24CA98.4050703@fibertel.com.ar>

Sending this again, someone have an idea?

Ernesto


     we have a problem with a project after updating it to IPy 2.6.1. We 
need to use a COM library; we add the reference in VS which creates the 
interop.XXX file. In IPy v1.1 we could access the imported types 
directly, like

LN_AclEntry = LN_dbACL.GetEntry(entryName)

if (LN_AclEntry == None):
   DebugMessage("%s entry does not exist in database: %s" %(entryName, 
databaseName))
else:
   if (LN_AclEntry.Level >= ACLLEVEL.ACLLEVEL_DESIGNER):
     ...

the important line here is the last one: in IPy 1.1, LN_AclEntry is an 
instance of LN_AclEntry {Domino.NotesACLEntryClass}. In IPy 2.6.1, this 
same variable is of type LN_AclEntry {System.__ComObject}.

This means we can't access Level property and compare with ACLLEVEL 
enumeration.

Is there something we can do to get v1.1 behaviour back? If not, can we 
cast somehow the object to the correct type?

Thanks in advance,

Ernesto Cullen

I noticed this as well when one of the recent commits came through,
figured it was going to be dealt with in good time.

While the plan is to remove support for .NET 2.0 (which required some
extra classes) and make .NET 4.0 will be the official target, the
project files in IronPython_Main still have all the .NET 2.0
references (with conditionals that MSBuild respects and VS seems to
ignore). I assume these will be removed at some point, but until then the
IDE is going to report these as issues.

I think that's a fair summary and ties into what I was saying about cross function switching.  So basically this means every method needs to be re-written to support this including dispatching calls via returning back to an outer loop and then dispatching to the called object with the new arguments (including the perf hit that would come with that).  I think that can certainly be done with a DLR tree AST re-write and replacing normal invocation with this trampoline mechanism.  Obviously it'll come with a significant perf hit as we need to allocate memory for local variables, calls with be slower as they need to return and call, etc...

But if you can get the tree re-write going to make the code entirely stackless from there you could opt into to the tree re-write dynamically.  That could be done by doing a simpler tree re-write to track where you are in the function and then throwing a .NET exception when the 1st switch occurs.  There would need to be try/catch/rethrow blocks to save all of the relevant state (which would need to be in locals) and then all of the functions on the stack would need to be re-written with the full stackless re-write.

I do agree that it sounds more difficult then what is going on with the CPython implementation.

Subject: Re: [IronPython] Implementing Greenlets API in IronPython

I have been trying to hire somebody to implement the greenlet extension module, which would enable modules like eventlet and gevent to work on IronPython.  The person I currently have looking into it, however, isn't hopeful. A condensed version of his perspective is below.  Perhaps the IronPython list (Dino?) has an idea for a solution?

== Response to Greenlets on IronPython ==

I looked at various solutions but none of them seem to arrive at the correct solution. I did try generating the DLR using AST again to make the function stackless but the limitation is with python and .NET.

Let me explain the issue.
1) .NET lanugages (C#. VB.NET<http://VB.NET> etc.) are strongly typed. In other words, if I get a variable I know what its type is at compile time. IronPython actually compiles the functions into CLR and runs them on the fly. A function is compiled once and can be executed again and again. One must know that the function needs to be stackless at compile time and a function cannot be made stackless at run time.
2) Python is a typeless language. A variable can assume any type at any point in execution at run-time. Now consider the following code in Python using the greenlet API:

a = greenlet(foo)

def abc():
    print "X"
    a.switch()
    print "Y"

Although variable a is defined, it does not have a strong type and during execution, a can be assigned a different object which can also implement the switch function and the code will execute fine.

As mentioned above, IronPython needs to know at compile time that the function has to be made stackless. In python since a is not typed, a can be greenlet in one execution of abc and any other object in the second call. Also, there is no way to determine at compile that the function abc needs to be made stackless since it needs to switch since the type of a is unknown till it is actually called at runtime.

Hence is it next to impossible to implement the switch because of the above implementation.

CPython dos not compile the functions and does not use the yield keyword (which is not avilable in C/C++ anyways) to do it. It does this by using context switching which is built into python and so the API is fairly straightforward in CPython. CPython basically has the stack of all previous functions calls and saves the stack so that it can resume later from that point. It needs to store the context and uses the inherent context switching built into Python to do it.

== End Response ==

Ideas?

>From there I think you just need to worry about having to save multiple frames (which I get the impression is supported from the docs - eg f() calls g() and then g switches).  For that you'll probably want to re-write all of the dynamic expressions in the generator (these show up in several forms though based upon how we're generating code-  there's a ReduciableDynamicExpression and some PythonDynamicExpression's floating around now).  If greenlets only works across calls then you just need to intercept the ones which are using invoke binders.  If you can have a descriptor who's __get__ or __set__ switches then you'd also need to handle gets/sets/etc...  If you can do something like import a module which hasn't been loaded yet and then have the top-level module code switch then you'll need to start getting really creative :)  You'll then presumably need to change these into using some trampoline to do the actual invocation.

Hopefully that will get you started - I'm sure there'll be lots of little issues so if you have questions feel free to ask.  If you get it all working we can figure out what exactly we need to make public and how we should expose that so you can do this as an extension - but I'm sure you'll initially be using a bunch of internal APIs.

Hi -

The greenlets C-extension module (http://packages.python.org/greenlet/)  provides a very basic api that is used by eventlet and gevent to provide asynchronous programming constructs.  It would be nice to have a reasonably performant version of the greenlet API in IronPython.

Before I start playing around with possibilities, is there an obvious approach to implement the greenlets API in IronPython?

Thanks
Tristan

I noticed this as well when one of the recent commits came through, figured it was going to be dealt with in good time.

While the plan is to remove support for .NET 2.0 (which required some extra classes) and make .NET 4.0 will be the official target, the project files in IronPython_Main still have all the .NET 2.0 references (with conditionals that MSBuild respects and VS seems to ignore). I assume these will be removed at some point, but until then the IDE is going to report these as issues.

One qualifying remark to add here - we will continue to ensure we build against .NET 3.5 and above from the DLR's CodePlex source repository, not IronPython's.  If anyone's interested in doing this today simply:
1. Navigate to http://dlr.codeplex.com/SourceControl/list/changesets
2. Download a source zip file of your choosing
3. Unzip it and build the "v2Release" configuration of "DLR_Main\Solutions\CodePlex-DLR.sln" as opposed to the "Release" configuration of "IronPython_Main\Solutions\IronPython.sln"

Just out of curiosity, how many people out there care about building IronPython against .NET 2.0/.NET 3.5?  I'd hope not too many considering the improvements you'll get by running .NET 4.0 based IronPython assemblies - see http://knowbody.livejournal.com/20751.html :)

Thanks,

Dave

But I think we do intend to ensure that we still build on .NET 3.5 and above - we just won't be releasing those binaries ourselves.  .NET 2.0
SP1 will be dropped completely and we won't be doing our normal extensive test passes on .NET 3.5.

I care about Mono support. I believe the trunk is 4.0 compatible but
binaries currently do not exist for most platforms.  It would be nice if
there was some minimal amount of testing against Mono to ensure major
IronPython releases were cross platform.  I do not believe there are major
problems with Mono and IronPython currently and hopefully this can remain
the case.

It's a good point - if Mono 2.8 isn't out in time for 2.7 then we'll need to
think about what to do there.  Over on the Mono list there was some discussion
about this in April (http://lists.ximian.com/pipermail/mono-list/2010-April/044892.html) 
and it sounds like the release was supposed to be available soon after .NET 4
shipped but it's still listed as TBD on the roadmap page :(  Either way there's
still ~6mos before 2.7 is done so there could be a good chance Mono 2.8 will be
out by then as well.

Subject: [IronPython] cannot find Pickle file from ASP.NET Web app
Message-ID: <002b01cb17d4$4f705aa0$ee510fe0$@com>

 

Hello,

 

The following Python code snippet causes a FileNotFound exception from an
ASP.NET Web application:

 

input = open('t2.pkl', 'rb')

 

The exception message is:

 

[Could not find file 'C:\Program Files (x86)\Common Files\Microsoft
Shared\DevServer\10.0\t2.pkl'.]

 

The same code works for a console project.

 

Any suggestions?

 

Thanks,

William Johnston

Are you running the WebDev server from Visual Studio? If so, that
directory is the default "working directory" for the
WebDev.WebServer.exe (the ASP.NET server), and thus where IronPython
will look for files when you use 'open'.

By default, IronPython doesn't know that you're running in a web app
and thus follows the system rules for locating files. The same thing
happens in C#/ASP.NET as well, by the way, if you don't handle it
properly..

You need to use Server.MapPath to get a path that 'open' can handle.
It'll look something like

   open(Server.MapPath('~/t2.pkl'), 'rb')

Server.MapPath converts a webapp-relative path to a filesystem path
the open will understand; the '~/' just means the root of the web app.

Hello,

 

I attempted to set the path to the CPickle file using SetSearchPaths but
this also did not work:

 

searchPaths.Add(Server.MapPath("."));

 

var ipy = Python.CreateRuntime();

ipy.GetEngine("python").SetSearchPaths(searchPaths);

 

I still cannot access my .pkl file.

 

Any more suggestions?

 

Thanks.

Hello,

 

The following Python code snippet causes a FileNotFound exception from an
ASP.NET Web application:

 

input = open('t2.pkl', 'rb')

 

The exception message is:

 

[Could not find file 'C:\Program Files (x86)\Common Files\Microsoft
Shared\DevServer\10.0\t2.pkl'.]

 

The same code works for a console project.

 

Any suggestions?

 

Thanks,

William Johnston

SetSearchPaths is used to set up sys.path, which controls where to
find libraries for importing.

To find files without a full path, IronPython will look in the
directory your hosting application was launched from. What that
directory is will depend on how you launch your hosting application:
from the command line, from Visual Studio, or from Windows Explorer.

You can set the current directory by setting
System.Environment.CurrentDirectory, but this is not usually a good
idea.

Fixes a bug w/ the offsets we?re reporting for tokenization inside of VisualStudio.  We aren?t respecting initial location and we?re not clearing _newLines when re-initializing the tokenizer.  The parser is also failing to set the span on the function associated w/ a lambda expression.

Subject: [IronPython] IronPython version on gestalt.ironpython.net?
Message-ID: <AANLkTil-qVHLstfKKPWkm77BwS0fjMvhwO9O8V6cdkWY@mail.gmail.com>

Hi,
Which version of IronPython is on gestalt.ironpython.net? It looks to
me like it's IronPython 2.6.0, since I'm hitting issues that are
supposed to be fixed in 2.6.1.
