In theory ScriptEngines should be independent and able to run in
parallel without issues. However, there might be interactions with
other parts that still have threading issues (this, BTW, is why
CPython uses a GIL - writing a free-threaded runtime correctly is
*hard*, and it's far to easy to bugs to slip in inadvertantly.)

It looks like this is that same as
https://github.com/IronLanguages/main/issues/1173 that was opened
recently with basically the same problem - there might be a race
condition in the weakref module. I'll try and track it down since
there's a couple of good small test cases to work from.

Hi,


This is about: https://github.com/IronLanguages/main/issues/1173

I have never analysed IronPython source code, I just try to help you.

I modified:

IronPython-2.7.5\main-ipy-2.7-maint\Languages\IronPython\IronPython\Runtime\WeakRef.cs

to this:

        public void ChainCallback(object callback, object weakRef) {

            lock (callbacks)

            {

                callbacks.Add(new CallbackInfo(callback, weakRef));

            }

        }



Now it is better.



Now sometimes I get this exceptions:

'module' object has no attribute '__all__'

   at Microsoft.Scripting.Runtime.LightExceptions.CheckAndThrow(Object 
value)

   at os$10._get_exports_list$98(PythonFunction $function, Object module) 
hely: C:\Program Files (x86)\IronPython 2.7\Lib\os.py, sor: 39

   at IronPython.Runtime.FunctionCaller`1.Call1(CallSite site, CodeContext

   at os$10.os(FunctionCode $functionCode) hely: C:\Program Files

   at IronPython.Compiler.RuntimeScriptCode.Run(Scope scope)

   at IronPython.Runtime.PythonContext.InitializeModule(String fileName,

   at IronPython.Runtime.PythonContext.CompileModule(String fileName, String 
moduleName, SourceUnit sourceCode, ModuleOptions options, ScriptCode& 
scriptCode)

   at IronPython.Runtime.PythonContext.CompileModule(String fileName, String 
moduleName, SourceUnit sourceCode, ModuleOptions options)

?

I do not know why but I cannot localize the error because

putting breakpoint to LightExceptions.CheckAndThrow(Object value) method was 
not working

and this error  rarely occurs

Best Regards

David

Subject: [Ironpython-users] Strange exception in os.walk
Message-ID: <727D8E16AE957149B447FE368139F2B53CD2747E@SERVER10>

Hi,

One of my coworkers struggles with strange exceptions when he calls os.walk from his python script.

The script is running in IronPython 2.7.4, hosted by CODESYS.

16:04:05 [Information] # Start building AC_Mechatronics at c:\jenkins\workspace\Build_Libraries\source\Application\ApplicationComposer\AC_Mechatronics\AC_Mechatronics
16:04:05 [Error] Unable to cast object of type 'Microsoft.Scripting.Runtime.Uninitialized' to type 'System.Exception'.
16:04:05 [Error]   File "c:\jenkins\workspace\Build_Libraries\scripts\BuildLibraries.py", line 453, in build_library
    library_state = get_library_state(sharp_client, lib_root, dest_repo, srcpath_parsed)
  File "c:\jenkins\workspace\Build_Libraries\scripts\BuildLibraries.py", line 415, in get_library_state
    project_info = load_project_info_object(lib_root)
  File "c:\jenkins\workspace\Build_Libraries\scripts\tools.py", line 96, in load_project_info_object
    for root, dirs, files in os.walk(project_root):
  File "C:\jenkins\workspace\Build_Libraries\cds\Targets\default\ScriptLib\3.5.5.0\os.py", line 294, in walk
    for x in walk(new_path, topdown, onerror, followlinks):
  File "C:\jenkins\workspace\Build_Libraries\cds\Targets\default\ScriptLib\3.5.5.0\os.py", line 276, in walk
    names = listdir(top)


The problem is currently reproducible on a single machine, which happens to be a build server, but unfortunately not on our developer machines.

Googling the exception code does not help, either.

We're currently trying to get more information, including .NET stack traces...

In the meantime, does anyone here have any idea for further diagnosis?

Best regards and thanks in advance,

Markus Schaber

Hi, Pawel,

As far as I can see, we're not passing -X:Tracing, but we're using Frames and some other options, and a tracebackhandler may be added by the host.

I'll investigate in that direction.

Thanks!

HI All,


I am trying to add reference and import BMAPIa.DLL library using CLR. But it is throwing an error message.

My code:

Import clr
Clr.AddReferenceToFile("BMAPIa.dll")
Import BMAPIa

Error:

C:\Users\Administrator>"C:\Program Files (x86)\IronPython 2.7\ipy.exe" "C:\Users\Administrator\Desktop\AMD64\test.py"
Traceback (most recent call last):
  File "C:\Users\Administrator\Desktop\AMD64\test.py", line 9, in <module>
SystemError: The module was expected to contain an assembly manifest. (Exception from HRESULT: 0x80131018)

Please let me know where am i going wrong?

FYI.... This is library is written in C++ and I am not aware of in which .NET framework it is been built.

Do you mean the library is CLI/C++, or is it native C++? If native C++, it
won't work with IronPython currently.

Hi,

Thanks for your reply.

How to check the library is native C++ or not?

If it is a native C++ then, is there any work around for the same.

Where did you get the library? If it is native, then you would have to
write a wrapper library in C# or CLI/C++ that interacted with the library
through P/Invoke (for C#) or the native function calls if CLI/C++.

Thanks for info markus,

Can you please send me sample code to use ctypes and also COM interface?

Hi,

I fit is not explicitly stated that it is C++/CLI (or some other keywords like ?mixed mode? or ?managed C++), I?d guess that it is pure native.

The library might expose a COM interface, in that case you could interact with it using COM.

Another way for a wrapper could be using the ctypes module from the standard library.

Hi, Herman,

Sorry, I did not use any of those two myself yet, just heard some success (and a few failure) stories of others.

http://ironpython.net/documentation/dotnet/ contains some explanations and sample code for COM.


For ctypes, which _should_ work the same as in cPython, there are lots of examples and tutorials on the net: http://python.net/crew/theller/ctypes/tutorial.html


In both cases, I guess you will need basic knowledge of COM or C calling conventions and memory layout to be successful.

Hi,

Just some additional thoughts / gut feelings:

The COM interfacing which is based on the .NET COM support seems to work rock solid / very stable.

The ctypes interfacing seems somehow brittle on corner cases, and is not easy to use in case of complex data structures, C++ interfacing may be even impossible. I guess, in those cases, you should create a wrapper DLL using C++/CLI ? you can check the SharpSVN project for a very nice example of how to create a nice, OO .NET interface around a complex C interface.

Hi, Herman,

Sorry, I did not use any of those two myself yet, just heard some success (and a few failure) stories of others.

http://ironpython.net/documentation/dotnet/ contains some explanations and sample code for COM.


For ctypes, which _should_ work the same as in cPython, there are lots of examples and tutorials on the net: http://python.net/crew/theller/ctypes/tutorial.html


In both cases, I guess you will need basic knowledge of COM or C calling conventions and memory layout to be successful.

Best regards

Hi,

I fit is not explicitly stated that it is C++/CLI (or some other keywords like ?mixed mode? or ?managed C++), I?d guess that it is pure native.

The library might expose a COM interface, in that case you could interact with it using COM.

Another way for a wrapper could be using the ctypes module from the standard library.

Where did you get the library? If it is native, then you would have to write a wrapper library in C# or CLI/C++ that interacted with the library through P/Invoke (for C#) or the native function calls if CLI/C++.

How to check the library is native C++ or not?

If it is a native C++ then, is there any work around for the same.

Do you mean the library is CLI/C++, or is it native C++? If native C++, it won't work with IronPython currently.

Hi ironpython,

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

In today's digest:ISSUES

1. [New issue] Index outside bounds of the array

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

ISSUES

1. [New issue] Index outside bounds of the array
http://ironpython.codeplex.com/workitem/35885
User varnonga has proposed the issue:

"I keep getting this script runtime error that says: Index Error: Index was outside the bounds of the array. I have had some success at fixing it, but do not understand why the thing I do works.

Basically, I take a copy of working code and copy it to the dysfunctional code. I them comment all the functional code out using the "#" symbol. Usually when I do this, it will work. I then delete the commented code out until it becomes dysfunctional.  I then add that commented code back in and verify it works.

Usually, I only get three or four extra lines of the commented code back into the original dysfunctional code (that is now functional). So what I do is retype the commented area to fit my design. 

It is like Python need to have that space taken up by something. Usually before I do all this, I check all my tabbing first and get rid of all the extra spacing on each line. Sometimes that helps if I have some weird spacing issue."

Just in case anyone is interested I have posted my Windows Forms based MIT

debugger at

http://1drv.ms/1I21dvl


The zip file is a Visual Studio solution, though the essential REPL and 
debugger files are pre-built and ready to use.

There is a help file in root folder of the zip that attemps an explanation 
of how to build and use it.

With many thanks to the IronPython team for a wonderful product.

Hi Markus

The actual REPL window is based on, and suitably acknowledged in 
IronTextBox.cs, an original MIT licensed project from CodePlex although to 
be honest there is not much left of the original code now I've finished 
hacking it around and improving! it. :)

The debugger is my own code so I can do whatever I want with that but as it 
is associated with IronPy, although it does work with ipy, I chose the MIT 
license for that as well.

I am no expert in licensing but I assume that I would need the permission of 
the original author to change the licence terms unless you can 
authoritatively assure me otherwise.

Best regards

Andy Graham

The license terms wouldn't need to be changed - including MIT licensed
code in an Apache 2.0 project is just fine. In this case I think it
belongs (for now) as a separate repo but I don't see a reason not to
include it under the IronLanguages project on GitHub.

Message-ID: <8E7ECE26-AFE4-4546-8B15-1A0BC5ABB05C@gmail.com>

Hi,

For a custom IronPython REPL I want to ?inject? some CLR extensions.
Until now we are doing the standard:
???
import clr, System
clr.AddReference(?System.Core?)
clr.ImportExtensions(System.Linq)
???
But I would like to avoid it. Although I know how to AddReference to System.Core from C#
and to get the Python Language Context I couldn?t find a way to call ImportExtensions from the Console.cs.

Any help will be appreciated.

Sorry the the delayed response. Your best place to start is probably
the .NET UIA API
(http://en.wikipedia.org/wiki/Microsoft_UI_Automation), which can be
easily called from IronPython.
