Subject: [Ironpython-users] Unable to correctly resolve function in a module
	when using ImportModule
Message-ID: <CAEsWva_BEE=8fZPvWKes50+rYoprtecDRniUUSx-VMzhgWhg7w@mail.gmail.com>

Hi,

I would like to call some functions in the scipy.linalg package from C#,
however I think the ImportModule function from the ScriptRuntime object is
not working correctly for modules with dots in the name.

To setup the project, I followed the instructions at

https://www.enthought.com/repo/.iron/

and then I created a C# console app, added references to IronPython,
Microsoft.CSharp and Microsoft.Scripting.  When I run the code below, the
GetVariable method of the ScriptScope object that is supposed to be
associated with scipy.linalg appears to be resolving to the scipy namespace
instead.  I also tried the code below with version 2.7.3 of IronPython
downloaded from ironpython.codeplex.com, but the code failed with an
identical result.

Am I doing something wrong, or missing something obvious here?

Cheers,
Matt


using System;

            options["Frames"] = true;
            options["FullFrames"] = true;

            ScriptRuntime pyRuntime = Python.CreateRuntime(options);

            dynamic sys = pyRuntime.GetSysModule();

It's definitely supposed to be handling dots (the code is in
Languages/IronPython/IronPython/Runtime/Importer.cs), so I'm not sure
why it would be failing in this case. Can you try it without SciPy
involved (just create a couple of nested packages with trivial Python
files)?

Hi there,




is it possible to use functools in IronPython 2.0? Im trying to import it and I get "no module named functools" but in this reference to IronPython 2.0 mentions it 
http://www.ironpythoninaction.com/magic-methods.html#id18
Any way to have it availabe in IP 2.0 without having to move to another version?
Greetings

Did you copy the std lib over? Why are you stuck with 2.0? It is a very old
version.

Message-ID: <50E5970F.6070602@peter-schwalm.de>

Hello,
I am trying to convert an Ironpython filewatcher program into a windows 
service. I started by translating a c# example to ipy. I tried to simply 
use System.ServiceProcess.ServiceBased, and received a message

"AttributeError: attribute 'ServiceProcess' of 'namespace#' object is 
read-only"

I also failed to import System.ServiceProcess.

I also tried to add a Reference to System.ServiceProcess.dll, and even 
that did not work.

Here are the code snippets ...

     # coding: latin-1
     import System
     import clr
     #clr.AddReference("System.ServiceProcess.dll")  # fails
     #import System.ServiceProcess                   # fails
     from System import Array

     class Program:
         @staticmethod
         def Main():
             x = System.ServiceProcess.ServiceBase   # fails
             print dir(x)
             ServicesToRun = 
System.Array[System.ServiceProcess.ServiceBase](
                 [
                 FolderWatch()
                 ])
             ServiceBase.Run(ServicesToRun);

     prg = Program()
     prg.Main()

Does anyone have an idea, how to accomplish that or - more generally - 
how to make an windows service out of an ipy program?

Thanks in advance
Peter Schwalm

When you add a reference to something in the GAC, don't add ".dll" to the
name. That is,

clr.AddReference('System.ServiceProcess')

Message-ID: <73E240587DC2724EB3736EE2AE2CDA5D012CDF@RHBARMEX02.purple.zebra.ad>

I'm an IronPython novice and would like some help.  I have a windows form that I have created in Visual Basic 2010 Express, which contains two text-boxes ('txtNumber' and 'txtResult') and a button ('btnSquare').  What I want to do is be able to call the below Python script ('Square.py') on clicking the button on the form;


class SquarePython:

    def __init__(self, number):

        self.sq = number*number

This script should square the number that is input in to 'txtNumber' and then output the result in to 'txtResult'.  I know this is almost too simple, but I just need to know the basics.  Here's what I have so far in my VB code;

Imports Microsoft.Scripting.Hosting

Imports IronPython.Hosting

Imports IronPython.Runtime.Types

Public Class Square

    Private Sub btnSquare_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSquare.Click

        Dim runtime As ScriptRuntime = Python.CreateRuntime

        Dim scope As ScriptScope = runtime.ExecuteFile("Square.py")

End Sub

End Class

Thanks in advance.

Subject: [Ironpython-users] ipy.exe hangs after closing IronPython WFP
	application
Message-ID: <927A025C392E9746A0DE744619AE6B01087B2253@CALMAIL-MBX3.smarttech.inc>


Here is the IronPython code I use to start and stop my app:
Perhaps the ShutdownMode has something to do with ipy.exe hanging (which seems to suggest app is not shutting down properly!)?

def Run_App_Threaded():
        global evt
        evt = AutoResetEvent(False)
        print "initializing..."
        thrd = Thread(ThreadStart(thread_start))
        thrd.ApartmentState = ApartmentState.STA
        thrd.IsBackground = True
        thrd.Start()

        evt.WaitOne()
        clr.SetCommandDispatcher(DispatchConsoleCommand)

def thread_start():
    try:
        global app
        app = Application()
        global mywin
        mywin = WpfApp1()
        mywin.Show()
        app.Startup += on_startup
        #app.ShutdownMode = ShutdownMode.OnExplicitShutdown
        app.ShutdownMode = ShutdownMode.OnMainWindowClose
        app.Run()
    finally:
        clr.SetCommandDispatcher(None)
        print "finally"
        itLives = Thread.CurrentThread.IsAlive
     print itLives
     print "hi"
     #if itLives:
     Thread.CurrentThread.Abort()
     print "Abort"
     #app.Exit(0) #exception: BoundEvent is not callable
     #app.Shutdown(0)
     #System.Environment.Exit(0) #this is the easy way to prevent it from hanging but, I want to do it RIGHT;)

def on_startup(*args):
     print "on_startup"
     global dispatcher
     dispatcher = Dispatcher.FromThread(Thread.CurrentThread)
     evt.Set()

def Close_App():
    #not on background thread, so we need to call Invoke
    print "invoking dispatcher"
    dispatcher.Invoke(Close_App_Delegate)

def Close_App_Delegate():
    mywin.Close_Window()
    app.Exit
    app.Shutdown()


>> Here is the output:
Finally
True
hi

>>Conclusion:
CurrentThread is Alive, but Abort doesn't work; ipy.exe  hangs with or without this call to Abort()???
Why isn't ipy.exe not exiting?

Subject: [Ironpython-users] [Newbee] - Ironpython and .Net - Problem of
	encoding accented characters
Message-ID: <50E60883.7070104@orange.fr>

Hi,

First, I wish you a Good Year and a Good Health.
For me I begin the year with a little stupid encoding's problem :

I  am doing a spellchecker with the Hunspell ' library for .Net -- > 
Nhunspell for a language of south of Europe with many accented 
characters. The spellchecker works fine with the words without accented 
characters but if there is some I have strange problem, exemple :

/self.mySpellChecker = NHunspell.Hunspell("xx_FR.aff","xx_FR.dic")//
//self.suggestions = self.mySpellChecker.Suggest("ome") /

If I give directly the word " ome" that is wrong version for "?me" "the 
man" the result, (self.suggestions) shall give me "?me" , "the man" and 
"?me" , "the hymn"... it is very good.

But if I take all the words of an Word's document 2007 I have created, 
when the loop is at the level of  "ome" the self.suggestions give 
nothing. I think it comes from the character accented.

The difference maybe comes from the 
/"self.theWords.Item(self.ltItemsErreurs[self.index]).Text)/" that 
gives  the word wrong but in a String's format. In .Net if I remember 
well the String's object is an Unicode ? I have tried to do unicode, 
decode, encode in iso-8859-15, my xx_FR.dic and xx_FR.aff are in UTF8, 
the Word's document is a 2007 version etc... I don't understand now, I 
am drowned in my error. Somebody can gives me some trails  ????

Thanks if somebody can give me some advice and sorry for my poor english,

And, this week, I am going to buy the book " IronPython in Action", I 
think that it will be better.
Cheers,
Bruno


_Suggestion's part of the program_/
         self.theWords.Item(self.ltItemsErrors[self.index]).Font.Color= 
255//
//        self.suggestions = 
self.mySpellChecker.Suggest(self.theWords.Item(self.ltItemsErreurs[self.index]).Text)//
////
//        if self.suggestions://
//            for sug in self.suggestions://
//                self._ltSuggestions.Items.Add(sug)//
//        else://
//            self._ltSuggestions.Items.Add("No proposition")//

         # the word before en black //

//        else://
//            self.index = self.index + 1/

_Little part of code to charge all the words and spell them:_

/ltItemsErreurs = []/
/        self.doc = 
self.word_application.Documents.Open("c:\\test\\LeTestUltime_2007.docx")/
/        self.lesMots = self.doc.Content.Words//
//        self.nbrMots = self.doc.Content.Words.Count//
//        for n in xrange(1, self.nbrMots)://
//            if self.lesMots.Item(n).Text.strip() not in 
self.ltLettresAEviter://
//                existe = 
self.monCorrecteur.Spell(self.lesMots.Item(n).Text.strip())//
//                if not existe://
////self.ltItemsErreurs.append(n)/

Hello bruno,
I dont't expect that to be a solution, but I see a little problem in 
your code for loading the word doc. You write:

/for n in xrange(1, self.nbrMots):/
         ...
If /self.lesMots.Item(...) is indexed starting with 1 (I don't if that 
is true), you will miss the last word, if is indexed starting with 0, 
you will miss the first word. That is because ranges in python 
asymmetric, i.e. in "range(a,b)/" b does not belong the elements of the 
range; the last element is (b-1).

So I think you will have to use either

     range(0, nbrMots)            # 0 ..

or

     range(1, nbrMots + 1)        # 1 ..

Good luck.
Peter

Thanks Peter,

It is true that I test only in the beginning of the text. Maybe I am 
going to have problem for the end. I am going to see my algorythm but 
...I have resolved my problem !

I must to say that I am a newbee but more, a stupid newbee. My problem 
was that the word coming from Word's Document some have space at the 
end. When I did

/wrongWord = //self.theWords.Item(self.ltItemsErreurs[self.index]).Text
/I have to write .strip() to clean my string /.
/Conclusion :/
/To have the SpellCkecker's suggestions in a right way I must write/:
/
//self.suggestions = self.mySpellChecker.Suggest( wrongWord.strip() )

//IronPython is very good//!

Cheers,
Bruno

Subject: [Ironpython-users] embedding and compiling
Message-ID: <50E6EF76.6050101@peter-schwalm.de>

Hello,
I want to use the embedding feature of ipy for implementing an ipy 
program as a windows service. I hope I can benefit from the good support 
of Visual Studio and C# for the installation of services (installUtil.exe).

My question is: is it possible to use pyc-compiled programs with the 
embedding features?

My plan is to code like this

     using IronPython.Hosting;
     using IronPython.Runtime;
     using Microsoft.Scripting.Hosting;
     ...

     ipyRt = Python.CreateRuntime()
     dynamic testPy = ipyRt.UseFile("program....py");
     ...
     testPy.function()

Is it possible to use compiled modules instead of "program....py" with 
.UseFile?

Thanks in advance
Peter

Hello,

I could figure it out myself now, not for a service yet, but for a c# 
console program. If anybody is interested here is the code snippet:

     class Program
     {
         static int Main(string[] args)
         {
             int rv = 0;
             // load the dll that results from ipy-compilation
             string AssemblyName = "outputMgrSvc1";
             Assembly assembly = Assembly.Load(AssemblyName);
             Dictionary<string, object> options = new Dictionary<string, 
object>();
             options["FullFrames"] = true;
             options["Frames"] = true;
             options["Tracing"] = true;
             ScriptRuntime runtime = Python.CreateRuntime(options);
             ScriptEngine engine = runtime.GetEngine("py");
             runtime.LoadAssembly(assembly);

             // initialize the script module
             ScriptScope scope = engine.CreateScope();
             string sourceString = @"from outputMgrSvc1 import *";
             ScriptSource source = 
engine.CreateScriptSourceFromString(sourceString,
                 Microsoft.Scripting.SourceCodeKind.Statements);
             try
             {
                 var x = source.Execute(scope);
             }
             catch (IronPython.Runtime.Exceptions.SystemExitException exc)
             {
                 object other;
                 rv = exc.GetExitCode(out other);
                 return rv;
             }

             // execute main procedure of script
             ObjectOperations ops = engine.Operations;
             dynamic names = scope.GetVariableNames();   // look at 
module data/procs
             dynamic proc = scope.GetVariable("scriptMain");
             try
             {
                 rv = proc();
             }
             catch (IronPython.Runtime.Exceptions.SystemExitException exc)
             {
                 object other;
                 rv = exc.GetExitCode(out other);
             }
             return rv;
         }
     }

Thank you
Peter

I'm pretty sure this is the best way to do it right now. It might be
possible to use the import machinery directly, but I'm not sure off
the top of my head.

Subject: [Ironpython-users] sitecustomize and compiled ironpython
Message-ID: <50ED4ED4.70306@peter-schwalm.de>

Hello,
I have a problem concerning the default encoding in ironpython console 
programs. In german windows editions there is a difference between the 
codepage in gui programs und console programs. Console programs use OEM 
encoding.

In the ironpython environment there happen implicit conversions between 
byte encoded files and unicode strings inside the program.

If I read textfiles containing german umlauts they are implicitly 
converted using the default encoding, in console programs OEM. If the 
text files are encoded using a different codepage (ANSI, cp1252), then 
conversion errors will happen if the file contains umlauts.

Normally I solve this problem by changing the default encoding in 
sitecustomize.py which is automatically called by site.py during program 
initialization. Now I have detected, that this mechanism will not work 
in ipy-compiled programs. It looks as if sitecustomize.py is not called 
in this environment.

Does anybody have an idea how to achieve an equally general solution for 
this problem? Is there perhaps a sort of stub-.py-file used by 
pyc-compilation where I can place the necessary call to 
sys.setdefaultencoding?

My ironpython version 2.7.1.

Thanks in advance
Peter Schwalm

Subject: [Ironpython-users] crash on Win8 64bit at IronPython expression
	evaluation
Message-ID: <478B4630361A43BEA481D28D38F32170@ZsidozPC>

Hi,

 

We are using IronPython and Windows 8 long time, but now we have an exception that only occurs on windows 8 64 bit. (We did not test on Windows 8 32 bit but tested on Windows 7 32/64 bit where it is ok.)

The application crashes at the first ironpython expression evaluating.

I think it is important to note that we are using IronPython from a background thread. We cannot debug it on windows 8. If this exception is similar to you please help us.

 

Thanks,

Zoltan

Are you able to narrow down the problem to a small script that reproduces it?

The code pointed to in that call stack doesn't really have many ways of failing in that way (null reference). The most likely thing is that DefaultContext.DefaultPythonContext is not being set. But I think that is done for you when the scripting runtime is initialized.

How are you creating the script runtime?

Running from a background thread shouldn't have any bearing on it, unless this were a race issue. And since the crash is happening in a static ctor, that pretty much rules out thread races.

People who should know (including Jeff Hardy) doubt it, but just to be complete:

Do any core IronPython devs live in the bay area? A local group
(PyLadies) is having a panel discussion with representation from
CPython, Jython and PyPy. It would be nice to have a FePy presence as
well :)

Are you using pyc to build an exe? If so, I don't think there is. Can
you not call sys.setdefaultencoding() at the start of your program,
from Python?

If not, you may need to look at the Python codecs library to manually
handle file encodings.

Hi ironpython,

Here's your Daily Digest of new issues for project "IronPython".

In today's digest:ISSUES

1. [New issue] GetEncodings called in StringOps.cs fails using Mono
2. [New comment] GetEncodings called in StringOps.cs fails using Mono

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

ISSUES

1. [New issue] GetEncodings called in StringOps.cs fails using Mono
http://ironpython.codeplex.com/workitem/33646
User TRJG has proposed the issue:

"I have submitted this verified bug to Mono because its technically their implementation of Text.GetEncodings() that is extremely flawed (and absolutely does not work). Since I have submitted it I have not seen much interest to fix it even though it absolutely does not return supported encodings. I figured I would let you guys know about it, and how IronPython's only call to this method ends up throwing an uncaught exception.

The GetEncodings() call I am referring to is in StringOps in the function MakeCodecsDict. What happen is when this calls is made, an array of hardcoded encoding names are returned. When called, the encodings fail and throw an exception that is not caught in IronPython.  Normally when GetEncodings() is called in .NET only supported encodings are returned, however is not the case with MONO. In fact, I'd argue that at this point GetEncodings() is pretty much guaranteed to fail on alot, if not most systems. (As a note, I am using OpenSuse 64 bit)

I'm not 100% sure but wrapping a try catch around &quot;NormalizeEncodingName&quot; might just fix the problem. 

Thanks,
Trjg"-----------------

2. [New comment] GetEncodings called in StringOps.cs fails using Mono
http://ironpython.codeplex.com/workitem/33646
User TRJG has commented on the issue:

"I have just confirmed that this technique works. Out of 95 encodings provided, 72 failed on my machine while 23 passed. 

Here is the simple code I used to check this.

static void Main()
{
    Console.WriteLine("Getting Encodings");
    var encodings = Encoding.GetEncodings();
    int successful = 0;
    int failed = 0;
    foreach(var encoding in encodings)
    {
        try
        {
            var name = encoding.Name;
            Console.WriteLine(string.Format("Encoding name is {0}",name));
            ++successful;
        }
        catch(Exception e)
        {
            Console.WriteLine("Got error.");
            ++failed;
        }
    }
    Console.WriteLine(string.Format("Successful {0}",successful));
    Console.WriteLine(string.Format("Failed {0}",failed));
}


I modded my personal source code of IronPython but have not yet personally tested it against the massive code base that I wrote and am looking to port to Linux. Mono's GetEncodings, and IronPython's call to it have been hanging me up thus far.

Thanks for the stellar library,
Mike"

Keith, you are absolutely right. Not the background thread causes this error.

I tried to make a simpler application that throws the same exception but I was not able to do it.

Then I tried to debug it in Visual Studio 2010 but if I debug then the error does not appears.

I cannot post the full application source code so we will give up it, because it is not reproduceable.

As a last word I would like to note that we have two windows 8 64 bit computer and on both pc the software crashes.



Regards,



Zoltan

Are you able to narrow down the problem to a small script that reproduces it?

 

The code pointed to in that call stack doesn?t really have many ways of failing in that way (null reference). The most likely thing is that DefaultContext.DefaultPythonContext is not being set. But I think that is done for you when the scripting runtime is initialized.

 

How are you creating the script runtime?

 

Running from a background thread shouldn?t have any bearing on it, unless this were a race issue. And since the crash is happening in a static ctor, that pretty much rules out thread races.

Hi,

 

We are using IronPython and Windows 8 long time, but now we have an exception that only occurs on windows 8 64 bit. (We did not test on Windows 8 32 bit but tested on Windows 7 32/64 bit where it is ok.)

The application crashes at the first ironpython expression evaluating.

I think it is important to note that we are using IronPython from a background thread. We cannot debug it on windows 8. If this exception is similar to you please help us.

 

Thanks,

Zoltan

ISSUES

1. [New comment] GetEncodings called in StringOps.cs fails using Mono
http://ironpython.codeplex.com/workitem/33646
User jdhardy has commented on the issue:

"If you do get it working, a github pull request or a patch on here is the easiest way for me to incorporate the fix."-----------------

2. [New issue] DAQMX Code which works fine with "Python 2.7.3" giving issue with IRONPYTHON
http://ironpython.codeplex.com/workitem/33648
User suma_putani has proposed the issue:

"Hello,

We are using National Instruments (NI) Driver 6501 for switch Testing. Below is the code which is written in Python 2.7.3. The same code does not work with Iron Python.

I don't think it is something to do with Physical Channel as the same code works fine for Python 2.7.3. 
Let me know if this is a Iron Python Issue. If so how to resolve it.

Or If I need to refer to Ctypes variable in a different way."-----------------

3. [New issue] DAQmxCreateDOChan() code which works in python does not works with ironpython
http://ironpython.codeplex.com/workitem/33649
User jayprakash has proposed the issue:

"My this line of code works well when i execute it in python:
nidaq.DAQmxCreateDOChan(taskHandle0,CreateChan,&quot;&quot;, DAQmx_Val_ChanForAllLines)

But when i execute the same come in ironpython i get an error code -200170(physical channel specified does not exist on this device)

I am clueless about how to solve this issue."-----------------

4. [New issue] Importing & reloading module leaks memory
http://ironpython.codeplex.com/workitem/33650
User ripedbone has proposed the issue:

"When I'm importing a module with __import__ and then reloading it with reload, it seems to leave the whole module into memory.

Here's a simple example code how to reproduce this. It's just importing and reloading a module which has two classes and the other one has a long list of methods just to get the module size bigger.

Garbage collection doesn't do anything with the memory until memory usage is ~600 Mb, which is quite strange. Furthermore, this maximum memory size is directly linked to the size of the imported module. Does anyone have an idea why? Or should I do the importing and reloading differently?

Just run attached import_test.py to reproduce the problem."

Message-ID: <CA+7con=UYXv9mCAtD_8xJqAEF8iiph0F60p9LqEHQ3xSTbWVKA@mail.gmail.com>

hi,


I am looking for a way to use module created as .net assembly as part of
the package

So instead of having:

import clr
clr.AddReferenceToFileAndPath(".\maplookup.dll")
import maplookup

I prefer:

import clr
clr.AddReferenceToFileAndPath(".\maplookup.dll")
import xmldiff.maplookup

Is there any way to accomplish it?

Thanks

What version of .NET is installed on the Windows 7 machines? I wonder if
this is a .NET 4.5 vs. .NET 4 issue and not a Win8 vs Win7 issue.

Not that I know of, but I don't think I've ever run the full test suite on
a .NET 4.5 machine. The basic stuff works, but that doesn't mean it doesn't
have some weird corner cases.

What is xmldiff? Is it an existing Python package?

Also, is maplookup just a .NET class, or is it actually a PythonModule class?

xmldiff is located in site-packages

this is PythonModule class but compiled separately from IronPython

[assembly: PythonModule("maplookup", typeof(maplookup.maplookup))]

namespace maplookup {
    public static class maplookup {
        public const string __doc__ = "test string";
    ...
}

I owe the explanation here. xmldiff is a python package with one module
implemented as C extension
What I am trying to do, is to port this C extension as .NET class.
This would be analog to porting build-in C modules into .NET but outside of
the IronPython.

Why not just add xmldiff to maplookup's namespace?  i.e. instead of
namespace maplookup {
    public static class maplookup {
        public const string __doc__ = "test string";
    ...
}
Write:
namespace xmldiff.maplookup {
    public static class maplookup {
        public const string __doc__ = "test string";
    ...
}

Thanks for the idea
The following appears to work as long as it is the only thing in xmldiff.

[assembly: PythonModule("maplookup", typeof(xmldiff.maplookup))]

namespace xmldiff {
    public static class maplookup {
...
}

however, if it try to mix it with other parts of the xmldiff package which
are pure python, it is not visible anymore.

for now the workaround is to create maplookup.py inside the xmldiff package
and load things indirectly


[assembly: PythonModule("_maplookup", typeof(xmldiff.maplookup))]

namespace xmldiff {
    internal static class maplookup {
...
}

import sys
if sys.platform=="cli":
    import os
    import clr

clr.AddReferenceToFileAndPath(os.path.join(os.path.dirname(__file__),r'maplookup.dll'))
    from _maplookup import *

Subject: [Ironpython-users] super() with classmethod - deviation from
	CPython 2.7 behaviour
Message-ID: <CAFBbO2SerCHfAKcxovp1gh+5i0-wdfyq7zgjM7TttL=ijoveNQ@mail.gmail.com>

Using the following script:
class A(object):
    @classmethod
    def x(cls):
        print cls.__name__

class B(A):
    @classmethod
    def x(cls):
        super(B,cls).x()

class C(B):
    pass

class D(B):
    @classmethod
    def x(cls):
        super(D,cls).x()

if __name__ == "__main__":
    B.x()
    C.x()
    D.x()

using CPython 2.7.3 (win32 build), I get the following:
B
C
D

Under IronPython 2.7.3 (64 & 32 bit builds), I get the following:
B
B
B

This also occurs for other class properties, e.g. __doc__ or other
classmethods - i.e. super() is improperly changing which class object
is passed in.

Cheers,


Michael

Hi Jeff,




You were right.

On windows 7 I managed to reproduce the error when I installed .net 4.5.

Unfortunately I still cannot make a simpler application that can reproduce it. 

And if I debug it then it works on Windows 7.


I have found that .net 4.0 and 4.5 cannot work side-by-side, so my next step will be downgrading my application to 3.5.



Or do you have better idea?




Zoltan

What version of .NET is installed on the Windows 7 machines? I wonder if this is a .NET 4.5 vs. .NET 4 issue and not a Win8 vs Win7 issue.

  Keith, you are absolutely right. Not the background thread causes this error.

  I tried to make a simpler application that throws the same exception but I was not able to do it.

  Then I tried to debug it in Visual Studio 2010 but if I debug then the error does not appears.

  I cannot post the full application source code so we will give up it, because it is not reproduceable.

  As a last word I would like to note that we have two windows 8 64 bit computer and on both pc the software crashes.

  Are you able to narrow down the problem to a small script that reproduces it?



  The code pointed to in that call stack doesn?t really have many ways of failing in that way (null reference). The most likely thing is that DefaultContext.DefaultPythonContext is not being set. But I think that is done for you when the scripting runtime is initialized.



  How are you creating the script runtime?



  Running from a background thread shouldn?t have any bearing on it, unless this were a race issue. And since the crash is happening in a static ctor, that pretty much rules out thread races.

  Hi,



  We are using IronPython and Windows 8 long time, but now we have an exception that only occurs on windows 8 64 bit. (We did not test on Windows 8 32 bit but tested on Windows 7 32/64 bit where it is ok.)

  The application crashes at the first ironpython expression evaluating.

  I think it is important to note that we are using IronPython from a background thread. We cannot debug it on windows 8. If this exception is similar to you please help us.



  Thanks,

  Zoltan

Message-ID: <CO1MSFTVADM02Bb5AGE0000987a@discussions.codeplex.com>

Hi ironpython,

Here's your Daily Digest of new issues for project "IronPython".

In today's digest:ISSUES

1. [New comment] GetEncodings called in StringOps.cs fails using Mono
2. [New issue] super() does not preserve class

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

ISSUES

1. [New comment] GetEncodings called in StringOps.cs fails using Mono
http://ironpython.codeplex.com/workitem/33646
User TRJG has commented on the issue:

"I just added a patch for the fix. Line 1885 in StringOps.cs

All I did was wrap the encoding name accessing in a try catch. If it fails, continue is called to try the next encoding."-----------------

2. [New issue] super() does not preserve class
http://ironpython.codeplex.com/workitem/33663
User mvdk has proposed the issue:

"In CPython 2.7.3, the following script:
class A(object):
	&quot;&quot;&quot;A funny class A&quot;&quot;&quot;
	@classmethod
	def x(cls):
		print cls.__doc__

class B(A):
	&quot;&quot;&quot;B funny class B&quot;&quot;&quot;
	@classmethod
	def x(cls):
		super(B,cls).x()

class C(B):
	&quot;&quot;&quot;C funny class C&quot;&quot;&quot;
	pass

class D(B):
	&quot;&quot;&quot;D funny class D&quot;&quot;&quot;
	@classmethod
	def x(cls):
		super(D,cls).x()

if __name__ == &quot;__main__&quot;:
	B.x()
	C.x()
	D.x()

produces
B
C
D
whereas on IronPython 2.7.3, it produces
B
B
B

This is independent of @classmethod: The following also triggers:
class A(object):
	&quot;&quot;&quot;A funny class A&quot;&quot;&quot;
	def x(cls):
		print cls.__doc__

class B(A):
	&quot;&quot;&quot;B funny class B&quot;&quot;&quot;
	def x(cls):
		super(B,cls).x()

class C(B):
	&quot;&quot;&quot;C funny class C&quot;&quot;&quot;
	pass

class D(B):
	&quot;&quot;&quot;D funny class D&quot;&quot;&quot;
	def x(cls):
		super(D,cls).x()

if __name__ == &quot;__main__&quot;:
	B().x()
	C().x()
	D().x()

with the same output"

Is it possible to launch the application directly and then attach the
debugger to it before the code in question executes?

How is the background thread created?

Subject: [Ironpython-users] Ironpython works with Framework 4 all or
 framework client profile ?
Message-ID: <50F6CFD1.2000707@orange.fr>

Hi all,

My question is in the title. I should like to be sure.

I did a program and I want to install it on another pc that have not 
framework 4.0 installed.
If I install Framework 4.0 client profile (smaller) my program does not 
work. If I install the Framework full, it works.

Conclusion : Ironpython works with the framework full, is it right ? It 
is not possible to install a smaller version of Microsoft Framework with 
IronPython like Framework client profile ?

Thanks if somebody can give me some informations about that,

Cheers,

Bruno

What exactly do you mean with "does not work"? Is there any exception?

Maybe your program does something which requires the full framework functionality, and it's not necessarily IronPython's fault...

Sorry , I don't say that it is the fault of Ironpython.

More precisions:
My program is created with Winforms and with Nhunspell (that is the 
version of spellchecker Hunspell for Net). My program is a little 
spellchecker for Word and for this I use the 
Reference('Microsoft.Office.Interop.Word').

When I run my program it asks to me that it needs the Framework 4.0
  "you first must install one of the following version of .Net 
framework:. Net Framework, version=v4.0"
but  the FrameWork 4.0 client profile is installed on this PC.

I don't think that Winforms and NHunspell need the full Framework 4.0 
but maybe the  "Microsoft.Office.Interop.Word". Am I right ?

Bruno

It's possible that this is a consequence of the TargetFrameworkAttribute
that's on the assemblies. It's set to
[assembly: TargetFramework(".NETFramework,Version=v4.0",
FrameworkDisplayName = ".NET Framework 4")]

rather than
[assembly: TargetFramework(".NETFramework,Version=v4.0,Profile=Client",
FrameworkDisplayName = ".NET Framework 4 Client Profile")]

Hi Curt,

I have developed this program with SharpDevelop.
I saw in the xml's file "app.config" this configuration's line and it 
was this:
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />

Well, I am newbee on .Net (I know Python/CPython) i did not paid 
attention to this line, sorry.
I did your modification,
<supportedRuntime version="v4.0" 
sku=".NETFramework,Version=v4.0,Profile=Client" />
it works good.

Thanks a lot Curt and Markus,
Cheers,
Bruno

Hi Everyone,




Thanks a lot of good posts for this thread.

We tried a lot of things but they were unsuccessful.

At the end we found that the windows update installed some 4.5 update for about a week.

Now everything is working. J

Is it possible to launch the application directly and then attach the debugger to it before the code in question executes?

How is the background thread created?

  Hi Jeff,




  You were right.

  On windows 7 I managed to reproduce the error when I installed .net 4.5.

  Unfortunately I still cannot make a simpler application that can reproduce it. 

  And if I debug it then it works on Windows 7.


  I have found that .net 4.0 and 4.5 cannot work side-by-side, so my next step will be downgrading my application to 3.5.



  Or do you have better idea?

  What version of .NET is installed on the Windows 7 machines? I wonder if this is a .NET 4.5 vs. .NET 4 issue and not a Win8 vs Win7 issue.

    Keith, you are absolutely right. Not the background thread causes this error.

    I tried to make a simpler application that throws the same exception but I was not able to do it.

    Then I tried to debug it in Visual Studio 2010 but if I debug then the error does not appears.

    I cannot post the full application source code so we will give up it, because it is not reproduceable.

    As a last word I would like to note that we have two windows 8 64 bit computer and on both pc the software crashes.

    Are you able to narrow down the problem to a small script that reproduces it?



    The code pointed to in that call stack doesn?t really have many ways of failing in that way (null reference). The most likely thing is that DefaultContext.DefaultPythonContext is not being set. But I think that is done for you when the scripting runtime is initialized.



    How are you creating the script runtime?



    Running from a background thread shouldn?t have any bearing on it, unless this were a race issue. And since the crash is happening in a static ctor, that pretty much rules out thread races.

    Hi,



    We are using IronPython and Windows 8 long time, but now we have an exception that only occurs on windows 8 64 bit. (We did not test on Windows 8 32 bit but tested on Windows 7 32/64 bit where it is ok.)

    The application crashes at the first ironpython expression evaluating.

    I think it is important to note that we are using IronPython from a background thread. We cannot debug it on windows 8. If this exception is similar to you please help us.



    Thanks,

    Zoltan

Subject: [Ironpython-users] Problems with silverlight chiron and script
	templates
Message-ID: <SNT136-W60782AC16145A52A7CAEBB93140@phx.gbl>


Hi to all!
I have tried to create a sample using the files in the Silverlight folder of the IronPython 2.7 distribution but I have met several problems:
1/ When running Chiron.exe on the files in script/templates, it complains about a missing System.Numerics assembly.I copied the associated dll and xml files from the Silverlight 5 sdk, files which are in the folder Silverlight/v5.0/Libraries/Client and now it works. I am just not sure I did the right thing because I also have these files in the Silverlight 4.0 and these files also make chiron work... Could someone please confirm I did the right thing by selecting v5.0 ?
2/ The page loads and the "Welcome to python and silverlight" message appears but a big diagnostic message appears :
"MethodAccessException: ?chec de la tentative d'acc?s de la m?thode 'Microsoft.Scripting.Utils.ReflectionUtils.CreateDelegate(System.Reflection.MethodInfo, System.Type, System.Object)' ? la m?thode 'IronPython.Runtime.Types.LateBoundInitBinder+FastInitSite`2<System.__Canon,System.__Canon>.CallTarget(System.Runtime.CompilerServices.CallSite, IronPython.Runtime.CodeContext, System.Object, System.__Canon, System.__Canon)'."
with the following traceback:MethodAccessException    at System.Delegate.BindToMethodInfo(Object target, IRuntimeMethodInfo method, RuntimeType methodType, DelegateBindingFlags flags)    at System.Delegate.CreateDelegateInternal(RuntimeType rtType, RuntimeMethodInfo rtMethod, Object firstArgument, DelegateBindingFlags flags)    at System.Delegate.CreateDelegate(Type type, Object firstArgument, MethodInfo method, Boolean throwOnBindFailure)    at System.Delegate.CreateDelegate(Type type, Object firstArgument, MethodInfo method)    at Microsoft.Scripting.Utils.ReflectionUtils.CreateDelegate(MethodInfo methodInfo, Type delegateType, Object target)    at IronPython.Runtime.Types.LateBoundInitBinder.BindDelegate[T](CallSite`1 site, Object[] args)    at System.Runtime.CompilerServices.CallSiteBinder.BindCore[T](CallSite`1 site, Object[] args)    at System.Dynamic.UpdateDelegates.UpdateAndExecute4[T0,T1,T2,T3,TRet](CallSite site, T0 arg0, T1 arg1, T2 arg2, T3 arg3)    at IronPython.Runtime.Types.PythonType.FastTypeSite`2.CallTarget(CallSite site, CodeContext context, Object type, T0 arg0, T1 arg1)    at System.Dynamic.UpdateDelegates.UpdateAndExecute4[T0,T1,T2,T3,TRet](CallSite site, T0 arg0, T1 arg1, T2 arg2, T3 arg3)    at Microsoft.Scripting.Interpreter.DynamicInstruction`5.Run(InterpretedFrame frame)    at Microsoft.Scripting.Interpreter.Interpreter.Run(InterpretedFrame frame)    at Microsoft.Scripting.Interpreter.LightLambda.Run3[T0,T1,T2,TRet](T0 arg0, T1 arg1, T2 arg2)    at IronPython.Compiler.PythonCallTargets.OriginalCallTarget2(PythonFunction function, Object arg0, Object arg1)    at CallSite.Target(Closure , CallSite , Object , Repl , IReplFormatter )    at System.Dynamic.UpdateDelegates.UpdateAndExecute3[T0,T1,T2,TRet](CallSite site, T0 arg0, T1 arg1, T2 arg2)    at _Scripting_(Object[] , Repl , IReplFormatter )    at Microsoft.Scripting.Silverlight.Repl.GetReplFormatter(Repl instance) 
And I really dont know what to do about it.
I also tried to port the samples from http://www.voidspace.org.uk/ironpython/webide/webide.html but they also generated the same kind of exception.
Thanks in advance for helping me. I am a pretty experienced python programmer looking forward to using it to manipulate the DOM but I am at a total loss regarding everything .NET

Is there a specific reason you can't put this into a pull request?

I've done so.  For some crazy reason I just didn't see the option
before (was probably blind or something).

Message-ID: <CAFBbO2SmX2otL1HXm3+s3=KnQHm2NNDmi9j+PX7m659NPNadSA@mail.gmail.com>

I put a pull request in for the fix for cp33663.  Are there any
comments on the fix?  I would really like it to be merged at some
point, because maintaining our own tree just for this fix seems a
little silly.  A real use case: Acceptance testing with unittest that
makes extensive use of setUpClass/tearDownClass (due to the expense of
starting some processes remotely).

Cheers,


Michael

Subject: [Ironpython-users] Windows Service Applications?
Message-ID: <CAMaNpgWuGH7u5-+EcWTuQwyO_uudgV3CcgLWEd8gtnm+w19Qhg@mail.gmail.com>

Hi all,

I'm new to IronPython.  I'm using IPy to wrap a .NET assembly.  I've got my
wrapper written and functional from the command line.  Now I want to run
the python wrapper as a windows service application.  Anyone know how I can
do that?

I found a project on codeplex that seems to be solving this problem (
http://dlrhostservice.codeplex.com/).  It's rather light on documentation
and I haven't been able to make heads or tails out of how to use the
project based on reading the source.  Any help in this area would be
appreciated.

Thanks,
Don Spaulding

Subject: [Ironpython-users] struct.pack(format, *args) not thread safe
Message-ID: <CAFBbO2RAfGAfhVSYMJPLXDSciPy8pUEzgmXi0J2UNWoTG51pTA@mail.gmail.com>

When using paramiko with more than one process spawning, I
occasionally get the following:

System.InvalidOperationException: The LinkedList node already belongs
to a LinkedList.
   at System.Collections.Generic.LinkedList`1.ValidateNewNode(LinkedListNode`1
node)   at System.Collections.Generic.LinkedList`1.AddFirst(LinkedListNode`1
node)
   at IronPython.Modules.PythonStruct.pack(CodeContext context, String
fmt, Object[] values)
   at CallSite.Target(Closure , CallSite , CodeContext , Object ,
String , Object )
   at paramiko.message$37.add_int$491(PythonFunction $function, Object
self, Object n) in
C:\repo\trunk\external\python\paramiko\message.py:line 227
   at paramiko.message$37.add_string$494(PythonFunction $function,
Object self, Object s) in
C:\repo\trunk\external\python\paramiko\message.py:line 259
   at paramiko.transport$13.open_channel$273(PythonFunction $function,
Object self, Object kind, Object dest_addr, Object src_addr) in
C:\repo\trunk\external\python\paramiko\transport.py:line 773
   ... Lots more in the stack trace.

I think that this is due to PythonStruct.pack's usage of CacheDict,
which is explicitly marked as not thread safe.  A quick and dirty hack
would be to force all users of _cache to lock it first, though I'm
sure there's a better answer.

Cheers,


Michael

Sorry, I've been crazy busy lately. I'll take a look this weekend.

Subject: [Ironpython-users] not a Zip file error
Message-ID: <CAKnwAjLzDKnyRG779Vhjo-0UPV1gpn7u14+k8=umPiZc-gb-ZQ@mail.gmail.com>

Hello List,

I am having a very weird error when trying to execute a very simple
python script from within a C# 2010 express project
Everytime the application executes the script, It crashes with the
following error

IronPython.Runtime.Exceptions.ImportException crossed a native/managed boundary
not a Zip file

I have managed to break down the issue into a small sample application as below.

The project is a blank project, that only contains the following code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Microsoft.Scripting.Hosting;
using IronPython.Hosting;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            ScriptEngine engine;
            ScriptSource source;
            ScriptScope sys;
            ScriptScope scope;

            String filename = @"c:\tmp\test.py";
            engine = Python.CreateEngine();
            source = engine.CreateScriptSourceFromFile(filename);
            sys = Python.GetSysModule(engine);
            scope = engine.CreateScope();
            source.Execute();   // CRASHES HERE
        }
    }
}

and the test.py is even simpler

import sys
import clr

clr.AddReference('System.Xml')
from System.Xml import XmlDocument

clr.AddReference('System.Windows.Forms')
from System.Windows.Forms import MessageBox

Oddly, if I comment out the 'from....' lines, then no error appears.
What is even more confusing to me is that if I compile the application
and run it using executable file, no error appears.

My project was working fine 2 days ago, and the only change I made
yesterday was that I un-installed C# 2010 express, rebooted and
re-installed it.

Does anyone know what is going wrong with my project

Thanks

Please dis-regard this issue. I have solved it.

I forgot that I turned on "Break when exceptions cross AppDomain or
managed/native boundaries" in options.

Thanks anyway

Hi ironpython,

Here's your Daily Digest of new issues for project "IronPython".

In today's digest:ISSUES

1. [New comment] Failure to bind base accessor if only one accessor is overridden in derived class
2. [New issue] struct.pack not threadsafe

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

ISSUES

1. [New comment] Failure to bind base accessor if only one accessor is overridden in derived class
http://ironpython.codeplex.com/workitem/31861
User mvdk has commented on the issue:

"On line 228 of PythonTypeInfo.cs: res = FilterSpecialNames(binder.GetMember(curType, name), name, action);

binder.GetMember(curType, name) needs flags to tell it to retrieve resp. GetField | GetProperty, SetField | SetProperty.  Perhaps these should be higher priority resolvers."-----------------

2. [New issue] struct.pack not threadsafe
http://ironpython.codeplex.com/workitem/33720
User mvdk has proposed the issue:

"When using paramiko with more than one process spawning, I
occasionally get the following:

System.InvalidOperationException: The LinkedList node already belongs
to a LinkedList.
   at System.Collections.Generic.LinkedList`1.ValidateNewNode(LinkedListNode`1
node)   at System.Collections.Generic.LinkedList`1.AddFirst(LinkedListNode`1

   at IronPython.Modules.PythonStruct.pack(CodeContext context, String

   at paramiko.message$37.add_int$491(PythonFunction $function, Object
self, Object n) in

   at paramiko.message$37.add_string$494(PythonFunction $function,

Object self, Object kind, Object dest_addr, Object src_addr) in
C:\repo\trunk\external\python\paramiko\transport.py:line 773
   ... Lots more in the stack trace.

I think that this is due to PythonStruct.pack's usage of CacheDict,
which is explicitly marked as not thread safe.  A quick and dirty hack
would be to force all users of _cache to lock it first, though I'm
sure there's a better answer.

Reproducing this has been troublesome (with what we have, I found that it triggered maybe once every 10 runs), but I'm sure that someone can think of a way :)"
