Re: [IronPython] multiprocessing in 2.7
If it is a 'C' based extension then it won't directly work with IronPython.
Maybe someone has a workaround / alternative?

Hi Romain,
AFAIK you have to download the Python standard library separately. See
e.g. http://www.ironpython.info/index.php/Using_the_Python_Standard_Library for
examples (I've done it a while ago, so had to Google around a bit).

Hi all,
I'm trying to use this feature in ironpython. I just follow the first
sample:
from multiprocessing import Process
def f(name):
print 'hello', name
if __name__ == '__main__':
p = Process(target=f, args=('bob',))
p.start()
p.join()
But I get the following error when I'm executing it:
c:\tempipy test-ipy-multiprocessing.py
Traceback (most recent call last):
File test-ipy-multiprocessing.py, line 1, in module
ImportError: No module named multiprocessing
Thanks for any help.
Regards.
Romain.
PS: I have just installed the last release of IronPython 2.7
c:\tempipy -V
PythonContext 2.7.0.40 on .NET 4.0.30319.1

Re: [IronPython] ironpython compared to powershell
Ironpython is a general purpose programming language whereas Powershell is primarily to replace the 'command prompt', batch file and vbscript within Windows system administration, though it appears in SQL Server 2008. Both have good .Net integration so you you could administer a network with either. Ironically IronPython is far more easy to deploy (xcopy) than Powershell which is a key factor in big tightly controlled networks.

Re: [IronPython] Autocomplete for .NET Types from IronPython with Wing IDE (update - better return type and parameter name handling)
Sorry for slow reply on this :-) Yes looks like I would be mad to reimplement something like Pysmell + PI for Wing. The next version of DIE *may* have very simple autocomplete enabled for strings, dictionaries and lists. It is more of a GUI exercise. Personally, I find an object browser more useful than autocomplete so I more likely to add write that first but, as the recent discussion on this list showed, it is a non-starter for many if an editor does not have autocomplete.

Re: [IronPython] MissingMemberException on 2.6
Hi Curt,
Sorry reported the wrong version there. I run the 2.6 interpreter but
have hard coded the build scripts to 2.01 ipy and the target folder
has the 2.01 binaries.
So it is all 2.01. Just tried the (same) compiled version on XP with
the same result. I built a console app without issue which ran so
looks like my code is doing something different :-)
Seems like I need to spend time narrowing down what is new since my
last build. I have introduced threading, use of dir (for autocomplete)
and changed external process handling so there is potential for
something to be up there.
Thanks.

Hi Curt,
Sorry reported the wrong version there. I run the 2.6 interpreter but
have hard coded the build scripts to 2.01 ipy and the target folder
has the 2.01 binaries.
So it is all 2.01. Just tried the (same) compiled version on XP with
the same result. I built a console app without issue which ran so
looks like my code is doing something different :-)
Seems like I need to spend time narrowing down what is new since my
last build. I have introduced threading, use of dir (for autocomplete)
and changed external process handling so there is potential for
something to be up there.
Thanks.

I don't think that this:
DataMicrosoft.Scripting/Data
Data0.9.0.0/Data
is the right AssemblyVersion for the 2.6 alpha. I would expect something
like 0.9.5.1. Is it possible that you're compiling with a different
version of IronPython than you think?

I've tried adding the references suggest on the mailing list:
clr.AddReference('System')
clr.AddReference('mscorlib')
But they were already there which suggests I have hit this before.
This all compiled and ran fine before I reinstalled the OS.
Anything else I can look at?

Re: [IronPython] MissingMemberException on 2.6
Hi Dino, When you say you're running the 2.6 interpreter does that mean you're using 2.6 to compile and then run against 2.0? If so that probably won't work. No - all building is done using 2.01 and 2.01 assemblies are used in the target bin folder. I've uninstalled 2.6 now just to rule it out altogether. Is there any chance you could attach a debugger to the dieing process and get the managed stack trace where things are blowing up? Think I've narrowed it down partly to the use of __name__ in the main script (which is not set to '__main__' when compiled) - easy to avoid that one. This would explain why the app sometimes did nothing! As I kept getting different results when troubleshooting this with different errors I suspect something was up with this PC install also. Can't get a repro or the real thing to consistently write an error to the event log so nothing to report for now :-) Thanks for the suggestions, Davy Mitchell ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com

Re: [IronPython] Modifying The PYC Stub EXE
Hi Dino, Thanks works great - you confused me with the semi-colons :-) Thanks Bruce too - your posts re:sys.argv were useful in looking at this. I'll raise a feature request of some sort. Is PYC ever likely to become part of the standard install? In case it is of use to anyone, I've put my modified PYC on my skydrive. Also has a modification for STA as I use the webcontrol in DIE. http://cid-1c5b93086198f54e.skydrive.live.com/self.aspx/Public/pyc.py Regards, Davy Mitchell On Tue, Apr 7, 2009 at 3:33 AM, Dino Viehland di...@microsoft.com wrote: Ahh, I see, you want to add something like: gen.EmitCall(OpCodes.Call, clr.GetClrType(Assembly).GetMethod(GetEntryAssembly), ()); gen.EmitCall(OpCodes.Call, clr.GetClrType(Assembly).GetMethod(get_CodeBase), ()); gen.Emit(OpCodes.Newobj, clr.GetClrType(System.Uri).GetConstructor( (str, ) )); gen.EmitCall(OpCodes.Call, clr.GetClrType(System.Uri).GetMethod(get_LocalPath), ()); gen.Emit(OpCodes.Newobj, clr.GetClrType(System.IO.FileInfo).GetConstructor( (str, ) )) gen.EmitCall(OpCodes.Call, clr.GetClrType(System.IO.FileInfo).GetMethod(get_Directory), ()) gen.EmitCall(OpCodes.Call, clr.GetClrType(System.IO.DirectoryInfo).GetMethod(get_FullName), ()) gen.EmitCall(OpCodes.Call, clr.GetClrType(System.Environment).GetMethod(set_CurrentDirectory), ()) right before we get the ScriptCode assembly in GenerateExe. It's really unfortunate that this is necessary. In theory we can burn a reference from your DLL into your EXE and have the CLR load the assembly and it should be able to pick it up w/o changing the CWD. The problem seems to be that we end up with DIE.EXE and DIE.DLL and it would appear the CLR always loads DIE.EXE and then it doesn't find the types in DIE.DLL. Presumably if we named them different this would work. Maybe we should enable naming them differently or maybe we should enable generating just one EXE instead of the wrapper EXE.

Re: [IronPython] ActiveX STA Issue in compiled Winforms EXE
Thanks Dino - works great now. Runtime speed is much snappier when compiled. One other thing I spotted is that pyc always builds a console app if /main is specified. elif arg.startswith(/main:): main_name = main = arg[6:] target = System.Reflection.Emit.PEFileKinds.ConsoleApplication Confused me for a bit :-) Have added this to Codeplex issue.

You can add this line to pyc.py right after mainMethod = … mainMethod.SetCustomAttribute(clr.GetClrType(System.STAThreadAttribute).GetConstructor(()), System.Array[System.Byte](())) and it should work.

[IronPython] Problem Importing WinForms IPY2.0 B5
Hi All,
Basic Repro is...
-form.py---
import clr
clr.AddReference('System.Windows.Forms')
from System.Windows.Forms import *
print len(dir(Form))
-test.py
from forms import *
print len(dir(Form))
Output:
538
443
My real world case is a subclass of Form is in another module. The module
that uses it tries to do mainform.KeyDown += self.DoSomething and fails as
KeyDown has vanished.
Yet if you copy and paset the subclass Form code into the same file it
works!
Forgive me if I am missing something obvious in the import mechanism :-)

[IronPython] Deprecation warning on Windows Form Double Buffered
Hi All,
With the following code I am getting a warning:
DeprecationWarning: Accessing protected method DoubleBuffered from
non-derived type Form
*import clr
clr.AddReference('System.Windows.Forms')

from System.Windows.Forms import *
class LDForm(Form):

Is this related to the import changes? I've not been doing much Pythoning
lately so sorry if I have missed something...

Re: [IronPython] Should DBNull treat as false ?
Hi there, I *think* this may be related to the Closed issue http://www.codeplex.com/IronPython/WorkItem/View.aspx?WorkItemId=14605 Dino stated at the time (with the last point being relevant here): NET conventions say that enum's should generally have a zero value (FxCop CA1008 :)). Because of that we can safely define __nonzero__ on enums and have that return true/false based upon if the value is zero/non-zero. Otherwise Python says all expressions otherwise defined return true, So I think the behaviour is correct though slightly counter intuitive in the case of Null.

Re: [IronPython] COM Late Binding in IronPython
Thanks very much Shri - this is a really good explanation. Particulary happy about wider DLR support as easier to sell the dynamic approach if other languages a possibility. I could see members of my team being cautious about using a 'off by default' feature in a beta of a strange language (to some!).

This relies on the use of interop assemblies for managed code to access COM objects. The interop assembly can be accessed in different ways: 1. clr.AddReference(interopAssembly) - This is the preferred mechanism so that the interop assembly does not have to be created multiple times. The down-side is that it complicates deployment. You have to ensurehttp://msdn2.microsoft.com/en-us/library/697w37zd%28VS.80%29.aspxthat the interop assembly exists on the machine. 2. Having IronPython automatically generate it on the fly - if you have a OLE automation object, IronPython tries to find its type library (TLB) and then to convert the TLB to an interop assembly on the fly using the TypeLibConverterhttp://msdn2.microsoft.com/en-us/library/system.runtime.interopservices.typelibconverter%28VS.80%29.aspxclass. The advantage is that this works seamlessly as long as there is a type library on the machine. The down-side is that this conversion can take a long time for large TLB files. This is how Word could be accessed. It requires the interop assembly Microsoft.Office.Interop.Word.dll to be available on the machine. c:\ipy.exe IronPython 2.0 Beta (2.0.0.1000) on .NET 2.0.50727.1433 Copyright (c) Microsoft Corporation. All rights reserved. import clr clr.AddReference(Microsoft.Office.Interop.Word) from Microsoft.Office.Interop.Word import ApplicationClass word = ApplicationClass() word.Visible = True doc = word.Documents.Add() doc.Range().Text = Hello from IronPython word.Quit() IronPython 2.0 has added support for interacting with OLE automation objects using the IDispatch interface. This completely eliminates the need for interop assemblies. This is the same mechanism that VBAhttp://msdn2.microsoft.com/en-us/isv/bb190538.aspxlate-bound code and also WSH http://msdn2.microsoft.com/en-us/library/9bbdkx3k.aspx use to interact with OLE automation object. This feature can currently be accessed using the -X:PreferComDispatch command line option. Here is an interactive session showing access to Word. There are no interop assemblies in the picture. c:\ipyd -X:PreferComDispatch IronPython 2.0 Beta (2.0.0.1000) on .NET 2.0.50727.1433 Copyright (c) Microsoft Corporation.

I cant say for sure when we will enable it by default, but its already quite stable for many real-world uses. We run all of our COM tests in both modes - using interop assemblies and using IDispatch. There are a few differences between the two cases in the minute details, but the mainline scenarios work well in both. This feature is implemented in the DLR, and so should be accessible from all DLR-based languages with little effort.

[IronPython] Late Binding in IronPython
Hi List, It seems odd posting here with my work hat on but here goes... :-) !! I've been looking at using IronPython and COM to work with some COM objects with VB6 (Project Compatibility - a *TOTAL* nightmare for interop). In VB.net we get round this with CreateObject which works well though somewhat limit. Is –X:PreferComDispatch flag intended to be an equivalent for IronPython and any other DLR languages? VBX?

There's a subtle difference between IronPython 2.0B1 and CPython 2.5 when sys.exit is called with a boolean parameter. CPython doesn't print the value of the parameter if it's boolean, while IronPython does. Presumably, CPython does this for backwards compatibility with a time when it didn't have a boolean data type. I'd guess that sys.exit(False) gets the same behavior as sys.exit(0) while sys.exit(True) is the same as sys.exit(1). But I haven't checked the CPython source to confirm that guess.

Re: [IronPython] [python] Import Performance
Hi All, Okay had a go at narrowing down the issue - appears to be the 'import compiler' line taking around 2 seconds. The importing seems pretty fast - possibly the exceptions in IronPython being generated causing the slowdown. Here's the test code I used: import sys import datetime print datetime.datetime.now() try: import antigravity except ImportError: pass print datetime.datetime.now() try: import compiler except ImportError: print Error \n, sys.exc_info()[0] for line in sys.exc_info(): print line print datetime.datetime.now() CPython: 2007-12-27 17:35:57.279000 2007-12-27 17:35:57.284000 2007-12-27 17:35:57.316000 IronPython: 2007-12-27 17:37:59.502000 2007-12-27 17:37:59.528000 Error exceptions.ImportError exceptions.ImportError No module named parser traceback object at 0x002B 2007-12-27 17:38:01.664000 Both cope with unknown modules fast but it appears the exception condition causes the slowdown. This is a common way for optional or preferred modules to be imported so I would say this is probably an issue though not having worked on anything large enough in IronPython to draw firm conclusions!! CPython seems to be about 10 times faster importing modules from the various benchmarks I have run. Easy workaround for me is to remove the import from configobj - hurrah :-) Cheers, Davy On Dec 26, 2007 9:56 PM, Michael Foord [EMAIL PROTECTED] wrote: Davy Mitchell wrote: I was curious as to why one of my apps was taking so long to start up.

Yes, very odd but I guess it is never safe to rely on the value of an enum.

There might be a few more changes that need to be made, but by and far IP now adheres to PEP 342. Another notable change brings the code closer to the new hosting API spec we published on this mailing list. The next couple of releases should finish that work.

Beginning with 2.0 Alpha 8, IronPython.sln (included in the source zip file) will be upgraded to VS 2008 format and we will only run our full test suite against binaries built from this. The 2005 version of IronPython.sln will then be deprecated although it will remain in the source zip file alongside IronPython.sln under the new name of IronPython2005.sln for some time. At this point it's unclear whether we'll continue to update IronPython2005.sln.

I don't yet understand the relationship between CPython and IP, so maybe idle can't be used. I want idle for the editing capabilities and so on that I'm used to using in the unix environment. So can Idle be used and if not, what else has the formatting that idle does? One guy here using a regular text editor and runs a batch file, but I'm hoping for a little more interactive environment. For licensing reasons, visual studio is a not an option for me at the moment but might be in the future. Well, you can edit IronPython code with IDLE - but I don't think you'll be able to run it. Keeping a command line window opening whilst editing with IDLE is pretty easy. Alternatively use a slightly more 'featured' editor that allows you to run files with an external command (most text editors will do this - plus it can be done with Python IDEs like SPE, Wing and probably Komodo).

Re: [IronPython] Announcement: Project to get some CPython C extensions running under IronPython
What would the issues be with NumPy - just the size of the API that I was most concerned with data types (and converting) which for statistical based computing needs to be exact. It is a great plus for DotNet to have common types between languages. After working for years in mixed VB6/C++ COM applications I really appreciate that :-) Are Resolver Users looking to reuse their existing code in spreadsheets or just have the same facilities? If the latter then SWIG for Dotnet seems a better option than COM and is more Mono friendly.

This is because in .NET threads don't have a backstop for unhandled exceptions (and it's generally considered a good thing, and a positive change in v2.0 - this helps prevent unhandled exceptions from going unnoticed). Obviously Python has made a different choice here (as did .NET v1.x) and so we respect that choice when you use the standard Python functionality. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Michael Foord Sent: Tuesday, October 09, 2007 12:07 PM To: Discussion of IronPython Subject: Re: [IronPython] [python] IP2A4 - Bug when Exception thrown on worker thread Davy Mitchell wrote: Hi - the following snippit crashes IP2A4.

[IronPython] INI File For IronPython
Hey Folks, Just wanted to pick a few brains... I was working on storage for GUI applications using INI files and CPython libs. I am looking to remove the dependency on Python 2 and do it all in DotNet. However as far as I can see there is not direct support for settings files - at least this is what I gather from all the implementations on the web of various XML/registry solutions none of which look too polished next to ConfigObj or the Python standard lib. How have other people solved this? Just need the basic name/value pair to sart with.

Ahh, I see. It looks like this info ultimately comes from custom attributes

(which I assume is where the VS side of things come in) and the IronPython

It would be theoretically possible to do this w/ the pyc sample and some
changes to the PythonCompiler class. The PythonCompiler class would need to
expose the AssemblyGen object and set the appropriate custom attributes on it
via, something like:
ag.myAssembly.SetCustomAttribute(new CustomAttributeBuilder(
typeof(AssemblyInformationalVersionAttribute).GetConstructor(new
Type[]{typeof(string)}), 2.0)
);
That has the downside of requiring you to compile your code (or at least your
main EXE). But basically it looks like we have no good support for this
right now.

Not sure if this is related to using or subclassing .Net objects - its

In case this helps other people with events in WinForms apps I hit a similar situation to this when handling events from the web browser control. To get the exceptions reported I simply put the entire handler in a try/catch block and printed it/them out.

[IronPython] Bug?
In the example below, hello is printed but there is no error for the
call on the non-existent method. Is this something to do with the
timer thread?

Happy 2007 Everyone, Early Developers Release Of TayLayout http://code.google.com/p/taylayout/downloads/list Unzip, cd to that dir and run slidenet.py or demo.py which are the sample applications. Some equally early docs exist at http://docs.google.com/View?docid=dd59dk39_2jh3xf9 There's loads I want to do with this little module but would love some feedback hence the early release. I have not tested yet on Mono. Also sorry but my website/blog will be down for a while more. If anyone else want to blog about this please do !! :-) Cheers, Davy Mitchell ___ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
Re: [IronPython] Do we have any option for Intellisense??
SPE (free) handles IronPython fairly well. Stani is having hosting problems so you may need to find a mirror site somewhere.

[IronPython] Subclassing a Control
Hi Folks, I was doing some IronPython for the first time in ages so forgive me if I am being dumb :-) Anyway I am trying to make a transparent label WinForm control: class TransLabel(Label): def CreateParams(self): cp = super(TransLabel,self).CreateParams cp.ExStyle = cp.ExStyle | 0x20 return cp def OnPaintBackground(self,e): pass The problem is the super call fails with: Traceback (most recent call last): File K:\MyDev\PyLP\helloWorld1.py, line 69, in Initialize File K:\MyDev\PyLP\helloWorld1.py, line 22, in __init__ File , line 0, in DefaultNew##12 File , line 0, in .ctor##26 File System.Windows.Forms, line unknown, in .ctor File System.Windows.Forms, line unknown, in .ctor TypeError: issubclass: arg 1 must be a class line22 is only self.label = TransLabel() Thanks and take care, Davy Mitchell -- Davy Mitchell Blog - http://www.latedecember.com/sites/personal/davy/ Mood News - BBC News Headlines Auto-Classified as Good, Bad or Neutral. http://www.latedecember.com/sites/moodnews/ ___ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
