Hi All, I was wondering if there was an estimated time frame to release IronPython 2.7.1?  Thanks Danny

Weird, I was just going to post that this afternoon :)

The current plan is to cut another beta today or tomorrow (once I fold in
the SSL patches), an RC on the 15th, and then the final 2.7.1 on the 21st.
I'm setting the 21st as the hard deadline (unless the RC is completely
FUBAR) because otherwise I clearly can't get anything out the door.

Needless to say, this is far longer than it should have taken, and the fault
is entirely my own. I apologize to those who have had good patches sitting
in the tree since April without a final release.

I'm going to work out a quaterly-ish release schedule from here on out, and
spend some time making the release process easier. Whenever the quarter
ticks around, as long as there are sufficient changes to make it worthwhile,
I'll cut another release.

- Jeff

I still need to sit down and finish my zipimport implementation, I know that
was something you wanted in for 2.7.1.

If you can get it done by the 15th, I'll take it. If not, I'll target
another release for January or February (I haven't decided on 3 or 4 month
cycles).

IronPython was built from the dlr-languages source package, which wasn't updated
for the current mono version, and did fail to build from source.

See https://bugs.launchpad.net/ubuntu/+source/dlr-languages/+bug/831402

If you want to provide an update/patch, please file an issue in the Ubuntu bug
tracker.

I'd really like to see dlr-languages in Ubuntu. The failure above is
from the IronRuby sources. I just built ironruby yesterday from git
with Mono 2.10.2, and worked fine for the regular config.

Does Ubuntu need an official release to be able to include
dlr-languages? Or can it be from current trunk?

BTW, there is this little issue for v2Release, which I sent to the
ironruby-core mailing list yesterday:

"""
When trying to build IronRuby for a v2Release under Mono 2.10.2, I'm
getting a failure:

% git clone https://github.com/IronLanguages/main.git IronLanguages
% cd IronLanguages
% xbuild Solutions/Ruby.sln /p:Configuration="v2Release"
...
Builtins/RangeOps.cs(307,17): error CS0266: Cannot implicitly convert
type `System.Collections.Generic.IEnumerable<IronRuby.Builtins.MutableString>'
to `System.Collections.Generic.IEnumerable<object>'. An explicit
conversion exists (are you missing a cast?)

Building for the regular configuration is fine.
"""

Which looks like an easy fix. Then there could be a common
dlr-languages release for v2 and v4. (I also have a patch that makes
dlr-languages build under Mono 2.6.7, which was a reason the iron
languages couldn't be added earlier, as that was the version of Mono
they were using).

No.

dlr-languages is a leaf package (no reverse dependencies or build dependencies),
so it should be sae to upgrade.  Best thing would be to provide a package in a
PPA, or provide the updated source package.

Matthias,

Thanks for the information! I see from the Ubuntu launchpad issue
tracker that Colin Watson has suggested that this get fixed in Debian,
and I see that you are a maintainer for libdlr0.9 in Debian unstable
[1].

I would like to know how to make a repository for Debian from the git
dlr-languages sources, but I suspect that it could take me a bit of
time to figure it out. Perhaps there is someone on this list that can
quickly describe these steps in order to quickly get the dlr into
Debian, and thus Ubuntu?

IronLanguages builds cleanly from git with Mono 2.10.2 with standard
Configuration, so this seems like it could be straightforward, with a
bit of help.

Any pointers appreciated,

-Doug

Subject: [Ironpython-users] IronPython 2.7.1 Beta 3 now available
Message-ID: <CAF7AXFH4Q=JnhkMS_AKu7+xvrEqvWVYKY_tkPjydPt53Z1xWDg@mail.gmail.com>

The third and final beta release of IronPython 2.7.1 is now available from
http://ironpython.codeplex.com/releases/view/74454. Like IronPython
2.7<http://ironpython.codeplex.com/releases/view/54498>,
this release *requires .NET 4 or Silverlight 4.* This release will replace
any existing IronPython installation.

The highlights of 2.7.1 are:

   - Updated the standard library to match CPython 2.7.2.
   - Add the ast, csv, and unicodedata modules.
   - Fixed several bugs.
   - IronPython Tools for Visual Studio are disabled by default. See
   http://pytools.codeplex.com for the next generation of Python Visual
   Studio support.


This release fixes even more bugs on top of what is fixed in 2.7.1 Beta 2.

See the current list of fixed
issues<http://ironpython.codeplex.com/workitem/list/advanced?keyword=&status=Fixed%7CClosed&type=All&priority=All&release=2.7.1%7C2.7.1%20Beta%201%7C2.7.1%20Beta%202%7C2.7.1%20Beta%203&assignedTo=All&component=All&sortField=LastUpdatedDate&sortDirection=Descending&page=0>
for
more details.

In particular, there is a fix for #26852 (ssl IE gets disconnected after
request, CPython doesn't. <http://ironpython.codeplex.com/workitem/26852>),
so if you have SSL errors on previous IronPython versions it would be
helpful to see if they are resolved with this version.

In particular, the updated standard library may have introduced some
undetected bugs. Please report any issues at
http://ironpython.codeplex.com/workitem/list/basic.

Hi ironpython,

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

In today's digest:ISSUES

1. [New issue] "import foo.zap as bar" throws AttributeError instead of ImportError
2. [New issue] Tracing traceback is missing line information for exception
3. [New comment] ssl IE gets disconnected after request, CPython doesn't.

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

ISSUES

1. [New issue] "import foo.zap as bar" throws AttributeError instead of ImportError
http://ironpython.codeplex.com/workitem/31545
User mkorpela has proposed the issue:

"The exception:
AttributeError: 'LightException' object has no attribute 'zap'

The defacto way in python to check if some module is available is:
try:
  import foo.zap as bar
except ImportError:
  bar = my_dummy_function

And this fails on IronPython, because an AttributeError is not an ImportError"-----------------

2. [New issue] Tracing traceback is missing line information for exception
http://ironpython.codeplex.com/workitem/31547
User dinov has proposed the issue:

"Run attached program, on IronPython it outputs:

0
15

On CPython it outputs:

11
15

This is because the traceback exception info is missing line information."-----------------

3. [New comment] ssl IE gets disconnected after request, CPython doesn't.

Hi,?

I am writing python scripts in a launched?ironpython console. I cannot use the pdb debug module because the FullFrames and Tracing were off. I cannot relaunch ipy -X:FullFrames -X:Tracing. Could you advise how to debug the scripts within the?existing?python console 2.7?

Thanks in advance,

Mike

Hi ironpython,

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

In today's digest:ISSUES

1. [New issue] Converting large float to int produces Int64 (which is not int or long)
2. [New comment] "import foo.zap as bar" throws AttributeError instead of ImportError
3. [New comment] IOError: Unable to write data to the transport connection: cannot access a disposed object.
4. [New comment] IOError: Unable to write data to the transport connection: cannot access a disposed object.

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

ISSUES

1. [New issue] Converting large float to int produces Int64 (which is not int or long)
http://ironpython.codeplex.com/workitem/31549
User mkorpela has proposed the issue:

"import sys
type(int(float(sys.maxint+1))) # --> Int64

This makes it hard to check if a thing is a number as it has a new type in IronPython that is not available in cPython or Jython."-----------------

2. [New comment] "import foo.zap as bar" throws AttributeError instead of ImportError
http://ironpython.codeplex.com/workitem/31545
User jdhardy has commented on the issue:

"It looks like IP is trying to raise the right exception (the 'LightException' object) but for some reason tries to look up 'zap' on that."-----------------

3. [New comment] IOError: Unable to write data to the transport connection: cannot access a disposed object.
http://ironpython.codeplex.com/workitem/31439
User jdhardy has commented on the issue:

"The SSL fixes are in the new 2.7.1 Beta 3 release. Can you give that a try and see if it fixes your issue?"-----------------

4. [New comment] IOError: Unable to write data to the transport connection: cannot access a disposed object.
http://ironpython.codeplex.com/workitem/31439
User loocas has commented on the issue:

"YES! Brilliant! It seems that the issue is gone! Thank you very much!"

I'm pretty sure that once the Python Engine has started, the options
cannot be changed.

If you have VS available you could attach to the ipy process and debug
using that. Calling System.Diagnostics.Debugger.Break() in your python
code will trigger a breakpoint.

Add the following to your script:

    import System; System.Diagnostics.Debugger.Break()

you may need `import clr` as well if you haven't already done so in that script.

HOWEVER, I had forgotten that this requires ipy.exe to be run with
-X:Debug, so it won't help you much.

Your best bet would be to bug the ANSYS authors to let you set command
line options for IronPython. If ANSYS just launches ipy.exe (as
opposed to embedding the engine), then you could replace their ipy.exe
with one that had the debug options hardcoded on; it's the
IronPythonConsole project in the source tree.

I would like to be able to call a C# something from a python script from IDLE or if better from ironpython.  The code I need to call is below.  I am fairly certain that this is VB.net so if easiest I could build this in a vb.net something.  I do not know how to package this into something that could be called from python (c# or vb -.net).  It would be most cool if I could call from ironpython.  Thanks.

Justin:
  May I humbly suggest that rather than calling a very nasty Visual Basic
routine, you could do the entire thing in Python more simply.
The following example uses an SQL query to obtain the same information as
the VB you supplied (if I understood the VB correctly.)
I think you'll find the Python a bit easier to read.

I spotted the error just after I hit "Send" ...
line 4 should have escaped the backslashes in the Windows-format filename
string, like:
    dbFile = r"C:\MyPath\MyGDB.mdb"
or alternatively, use forward slashes

Message-ID: <727D8E16AE957149B447FE368139F2B502C270@SERVER10.in.3s-software.com>

Hi,

For our embedded IronPython, we need to convert python scripts from string to files and back. To do that, I need to know the encoding of the python source for both ways, if there's one specified according to PEP 0263. (Our intended fallback is to UTF8 with BOM if none is specified.)

Are there any public utility functions in IronPython I can call to detect encoding markers in files and in strings?

Best regards

Markus Schaber

Python 3 has a "detect_encoding" function in the tokenize module that 
does this. You could copy and reuse that.

ISSUES

1. [New comment] Implement _elementtree module
http://ironpython.codeplex.com/workitem/21407
User pekkaklarck has commented on the issue:

"I'm surprised this issue is considered low priority because not having a working ElementTree implementation in IronPython is a big blocker for many Python programs. I know this is an open source project with limited resources but in this case there already is a working implementation that ought to be easy to take into use (see my nearly a year old comment above about ET 1.2.7).

What's worse than not having ET is having an implementation that can be imported but not used. This means that even if you install a working ET, any code that uses the "standard" way to conditionally import ET (see e.g. http://lxml.de/tutorial.html) still doesn't work because you end up getting a broken ET implementation anyway."-----------------

2. [New comment] ValueError: unmarshallable object
http://ironpython.codeplex.com/workitem/26489
User pekkaklarck has commented on the issue:

"I noticed that with IPY 2.7 you don't need --no-compile anymore. Apparently the compilation step in setup.py is just skipped."-----------------

3. [New comment] 'x'.replace(u'\uFFFE','') -> ValueError
http://ironpython.codeplex.com/workitem/29402
User pekkaklarck has commented on the issue:

"Seems to be fixed in IPY 2.7."-----------------

4. [New comment] print u'\xe4'.encode(sys.stdout.encoding) -> ?
http://ironpython.codeplex.com/workitem/29487
User pekkaklarck has commented on the issue:

"This occurs also with IPY 2.7. Notice that sys.stdout.encoding is cp437 both with IronPython and CPython. Some more experimenting below:


D:\>ipy
IronPython 2.7 (2.7.0.40) on .NET 4.0.30319.237

>>> import sys
>>> sys.stdout.encoding
'cp437'
>>> a = u'\xe4'.encode(_)

5. [New comment] os.path.abspath('*') -> ValueError
http://ironpython.codeplex.com/workitem/29489
User pekkaklarck has commented on the issue:

"Occurs also with IPY 2.7."-----------------

6. [New issue] Module __doc__ is None when using `ipy -m module.py`
http://ironpython.codeplex.com/workitem/31570
User pekkaklarck has proposed the issue:

"The problem is demonstrated by the example below. It occurs both with IPY 2.6.2 and 2.7.

D:\>type mymod.py
"""Hello, Kitty!"""

print "Greeting:", __doc__

D:\>ipy mymod.py
Greeting: Hello, Kitty!

D:\>ipy -m mymod
Greeting: None

D:\>python -m mymod
Greeting: Hello, Kitty!"-----------------

7. [New comment] Module __doc__ is None when using `ipy -m module.py`
http://ironpython.codeplex.com/workitem/31570
User pekkaklarck has commented on the issue:

"Because of this problem you cannot start Robot Framework (http://robotframework.py) like `ipy -m robot.runner` like you can with Python and Jython. We can add a workaround for this in future releases but that's still pretty annoying."-----------------

8. [New comment] Module __doc__ is None when using `ipy -m module.py`
http://ironpython.codeplex.com/workitem/31570
User pekkaklarck has commented on the issue:

"Ooops, it's obviously http://robotframework.org. There are separate instructions to get it working with IronPython [1] and we plan to ease the installation in RF 2.7 release (and having this particular bug fixed would help).

[1] http://code.google.com/p/robotframework/wiki/DotNetSupport"

Subject: [Ironpython-users] Warn user when using old print syntax
Message-ID: <727D8E16AE957149B447FE368139F2B502C476@SERVER10.in.3s-software.com>

Hi,

What is the easiest way to detect and warn the user when he uses the old print syntax?

It seems that "-3" aka "WarnPy3k" does not warn about it, and a simple check whether the user does "from __future__ import print_function" gives false positives if the user does not print at all.

Thanks!

Best regards

Markus Schaber

I think you'd have to patch the code to add the print check to the -3
warnings. Dino might be able to point out where you would do that.

So you want to warn if the file contains a print statement w/o from __future__ import print_function?  What if it's a call to print such as print('foo')  which is valid in both 2.x and 3.x?

Either way you should be able to just update ParsePrintStmt in Parser.cs.    But dealing w/ the case of the parens would be a little more difficult - but I think you can just peek at the next token after print and see if it's a parenthesis right after we eat the print keyword.

Hi,

I am trying to call our .NET service via remoting using IronPython

I have the transparent proxy object but I don't know how to cast it to
the interfaces (that are implemented by the server side object) 

 

I tried IServerInterface.SomeMethod(transparent-proxy-object) but it is
failing with "expected IServerInterface, got MarshalByRefObject"

 

How can I cast it to an interface?

 

I am using 2.7

 

Thanks in advance,

Tsahi Muyal

Hurm, maybe this is a different problem then...  Does:

import clr
clr.Convert(TransparentProxy, IServerInterface).IServerInterfaceMethod()

work?

If not then my guess is you might need a C# wrapper :(

I tried using typedproxy class
Not sure I am using it the right way

This is what I did

test = typedproxy(TransparentProxy, IServerInterface)

test.IServerInterfaceMethod()

This call is failing with "Expected IServerInterface, got MarshalByRefObject"

I debugged the code to find out where it is failing, it is in typedproxy (I marked the line)

class typedproxy(object):

The C# wrapper could be as simple as:

public static class MyWrapper {
                public static void IServerInterfaceMethod(object o) {
                                ((IServerInterface)o).IServerInterfaceMethod();
                }
}

Used like:

MyWrapper.IServerInterfaceMethod(TransparentProxy)

If you just want to call all static methods, or you can make an instance wrapper:

public class MyWrapper {
                private readonly IServerInterface _wrapped;
                public MyWrapper(object wrapped) {
                                _wrapped = (IServerInterface)wrapped;
                }
                public void IServerInterfaceMethod(object o) {
_wrapped.IServerInterfaceMethod();
                }
}

Used like:
MyWrapper(TransparentProxy).IServerInterfaceMethod()

Then you can pass around the wrapper object and just use it like a normal object.  If you need to get back to the transparent proxy for some reason you could add a property which returns it.

The clr.Convert(TransparentProxy, IServerInterface) is failing with same exception

I will code a C# wrapper but what does it mean? A client side assembly that will get the transparent proxy and convert it to the Interface type I need?

Hurm, maybe this is a different problem then...  Does:

import clr
clr.Convert(TransparentProxy, IServerInterface).IServerInterfaceMethod()

work?

If not then my guess is you might need a C# wrapper :(

I tried using typedproxy class
Not sure I am using it the right way

This is what I did

test = typedproxy(TransparentProxy, IServerInterface)

test.IServerInterfaceMethod()

This call is failing with "Expected IServerInterface, got MarshalByRefObject"

I debugged the code to find out where it is failing, it is in typedproxy (I marked the line)

class typedproxy(object):
    __slots__ = ['obj', 'proxyType']
    def __init__(self, obj, proxyType):
        self.proxyType = proxyType
        self.obj = obj
    def __getattribute__(self, attr):
        proxyType = object.__getattribute__(self, 'proxyType')
        obj = object.__getattribute__(self, 'obj')
        att = getattr(proxyType, attr)
        att2 = att.__get__(obj, proxyType) #This line is throwing the exception
        return att2

Any idea?

I'm not quite certain this is the same issue but you should try using the wrapper from this thread:

The transparent proxies always succeed when casting them to an interface type so it's hard for us to work w/ the objects when we need to check for certain interfaces ourselves.

Hi,
I am trying to call our .NET service via remoting using IronPython
I have the transparent proxy object but I don't know how to cast it to the interfaces (that are implemented by the server side object)

I tried IServerInterface.SomeMethod(transparent-proxy-object) but it is failing with "expected IServerInterface, got MarshalByRefObject"

How can I cast it to an interface?

I am using 2.7

Thanks in advance,

Hi, Dino,

Considering our user base, I could ignore this corner case, as the user can simply get rid of the warning by adding the import statement.

Ok, I'll see whether I can do that.

Hi,

Sorry for disturbing again, but I'm a little bit confused about the ErrorListeners from the Hosting API.

For compilation of a ScriptSource, I can pass an ErrorListener which gets the errors and warnings, but it seems that I cannot pass an ErrorListener for the execution of the ScriptSource.

My guess is that the ErrorListener passed to the compilation is referenced from the compiled ScriptSource. Can you confirm hat? Or did I miss something?

Best regards

This guess seems wrong - it seems that the warnings are simply spit out on stderr by default.

Hi ironpython,

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

In today's digest:ISSUES

1. [New comment] Lib/config directory not present in zip distribution.
2. [New comment] Implement _elementtree module
3. [New comment] Implement _elementtree module
4. [New issue] Update ElementTree to IronPython compatible version

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

ISSUES

1. [New comment] Lib/config directory not present in zip distribution.
http://ironpython.codeplex.com/workitem/31417
User kenial has commented on the issue:

"It also happened to me. I'm using Mac OS X 10.6.8 and IronPython 2.7.1 beta 3 installed."-----------------

2. [New comment] Implement _elementtree module
http://ironpython.codeplex.com/workitem/21407
User jdhardy has commented on the issue:

"This issue is low priority because it refers to the _elementtree C accelerator module. To make ET work, IronPython needs a pyexpat implmentation ([workitem:20023]) or, as you pointed *last year* (sorry!), an upgrade to ET."-----------------

3. [New comment] Implement _elementtree module
http://ironpython.codeplex.com/workitem/21407
User pekkaklarck has commented on the issue:

"Submitted issue #31579 about changing ET implementation to IPY compatible version."-----------------

4. [New issue] Update ElementTree to IronPython compatible version
http://ironpython.codeplex.com/workitem/31579
User pekkaklarck has proposed the issue:

"The ElementTree implementation in IPY 2.6 and 2.7 is broken:

>>> from xml.etree import ElementTree as ET
>>> from StringIO import StringIO
>>> ET.parse(StringIO('<test/>'))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Program Files\IronPython 2.6 for .NET 4.0\Lib\xml\etree\ElementTree.py", line 862, in parse

File "C:\Program Files\IronPython 2.6 for .NET 4.0\Lib\xml\etree\ElementTree.py", line 1117, in __init__
ImportError: No module named expat; use SimpleXMLTreeBuilder instead
>>>

ElementTree 1.2.7 preview available at [1] has this comment: "ElementTree 1.2.7 preview is now available. This is 1.2.6 plus support for IronPython.". We've also used this version with Robot Framework [2] and at least in our relatively simple use it works great.

It might be worth checking how ET 1.3 alpha 3 works too. It's newer than 1.2.7 so it could have same IronPython fixes. CPython 2.7 uses ET 1.3 [3] so this would make IPY 2.7 API compatible with CPython 2.7 in this regard.

Notice that there's already work item #21407 about adding _elementtree module for the current ET implementation.

ErrorListener is only used for compiler errors; if you want to capture runtime errors you can put a try/catch around the call to ScriptSource.Execute().

It's not about the errors, but about the warnings. We run IronPython embedded (hosted) in our application, and want to capture the warnings to display them in a different window.

Is there a notion of "Warning" in context of execution? My understanding is that during execution you either get a single error, or you get the resulting value (or void/null if the script does not eval to a return value). Any print() messages are routed to the stdout stream which you can also intercept via the script engine's IO property. Perhaps that kind of trace output is what you are looking for?

It's not about the errors, but about the warnings. We run IronPython embedded (hosted) in our application, and want to capture the warnings to display them in a different window.

At least Python has that notion, and it has been ported to IronPython.

With switches like -t, -b, -3 and -Wall for IPy.exe, corresponding to the options IndentationInconsistencySeverity, BytesWarning, WarnPy3k and WarningFilters passed to Python.CreateEngine(), some of those warnings can be enabled.

While -t only has effect during compilation, -3 and -Wall trigger some warnings during execution (I'm not sure about -b.)

But it seems that those runtime warnings are handled completely inside the python warnings framework, and there the default is simply to write the warning to stdout. I guess I have to override the warnings.showwarning method (as it is documented for python) from hosting environment to achieve what I want.

The patch below emits a warning during Compilation for print statements whose argument list does not start with a '(' if Py3k warnings are enabled.

Thanks!

Can you make this a pull request on GitHub? It's much easier to manage
patches from there.

Subject: [Ironpython-users] Retrieving Ironpython variables within .NET
Message-ID: <CAM6pg+LTb2yQmq9GXt6rbKVGtZ4GWoHaW0FHd3gzQF=yUU3cSg@mail.gmail.com>

Hi Guys,


Im new to Ironpython and I was reading the book Ironpython in Action now in
Chapter 15, there is something i want to do but i just cant make it work. I
have the following script

 class Item:

    def __init__(self,value,quality):

        self.value = value

        self.quality = quality

number = 5;


variable = "Goodbye world!"

x = Item(5.0,"Good")


print x.quality


And I want to retrieve the variable "x" from C# change its value and inject
it back to Ironpython the problem I face is that well.. i dont know how. I
have tried with the scope.GetItems() but it returns 0. the only time it
returns the variables is when I Execute the Code, and if its possible I
would like to have it before...

                //Item is of size 0

                var items = _scope.GetItems();

                _code.Execute(_scope);

                //After execute items is size 5

                items = _scope.GetItems();



Thanks

In Python, the variable doesn't exist until the code is executed.
There's no way around that.

Hi,

Somehow, this patch leads to a StackOverFlowException in some cases, so please don't apply it.

(It seemed to work fine in my tests yesterday, though.)

I'm still investigating, but it seems that ErrorSink.Add tries to import the Warnings module, which itself triggers that warning recursively.

Maybe we should find a way to exclude the standard library from this kind of warning? I'll try to check how it is done for -t - or do we simply rely on the fact that the warnings module itself has a consistent indentation?

Best regards

Markus Schaber

The reason for that is that my tests yesterday involved only Compilation of ScriptSources. When actually executing a script, however, import of modules triggers their compilation, and then warnings are dispatched to the warnings module, instead of the ErrorListener used for Compilation.

You could add a thread static bool which tracks whether or not we're already reporting the warning, and if so don't recurse and report again.

Subject: [Ironpython-users] Getting started reference
Message-ID: <1318797194.2381.YahooMailNeo@web88616.mail.bf1.yahoo.com>

I've done some WPF in C# using VisualStudio 2010 and I've done some Python in IDLE, but I've never done IronPython using WPF in VS2010.

Are there any references or web pages to help people get to First base? (I'm looking specifically for IronPython WPF using VS2010 - I've found so many generic pages that my eyes are tired - but absolutely nada about what I need to get started.)? I have Foorde's book - but it pre-dates the integration of WPF, VS and IronPython, so it doesn't seem to help.


For example, I fired up VS2010, built an IronPython WPF application and added a button and a label. I have the XAML code and the PY code. 


But how do I reference the controls from my Python code-behind? I've tried the way I would do it from C# (e.g. label1.contents = "Hello World") - but that just gives me an "Unbound Name Exception" unhandled error. I even tried setting properties of "self" in the button_click handler - but that didn't work either.

This has got to be simple - can someone point me in the right direction?

?

Subject: [Ironpython-users] IronPython 2.7.1 RC Released
Message-ID: <CAF7AXFEZQ0hq6tmaL_n7uhSc4oZ-6z4pgqdspkz-RyoZ12FeyA@mail.gmail.com>

The first release candidate of IronPython
2.7.1<http://ironpython.codeplex.com/releases/view/71089>is now
available. Like IronPython
2.7 <http://ironpython.codeplex.com/releases/view/54498>, this release
*requires
.NET 4 or Silverlight 4.* This release will replace any existing IronPython
installation.

If there are no showstopping issues, this will be the only release candidate
for 2.7.1, so please speak up if you run into any roadblocks.

The highlights of 2.7.1 are:

   - Updated the standard library to match CPython 2.7.2.
   - Add the ast, csv, and unicodedata modules.
   - Fixed several bugs.
   - IronPython Tools for Visual Studio are disabled by default. See
   http://pytools.codeplex.com for the next generation of Python Visual
   Studio support.

This release fixes a few minor bugs from 2.7.1 Beta 3, namely making
ElementTree work and avoiding an exception on startup on Unix and MacOS.

See the current list of fixed
issues<http://ironpython.codeplex.com/workitem/list/advanced?keyword=&status=Fixed%7CClosed&type=All&priority=All&release=2.7.1%7C2.7.1%20Beta%201%7C2.7.1%20Beta%202%7C2.7.1%20Beta%203%7C2.7.1%20RC&assignedTo=All&component=All&sortField=LastUpdatedDate&sortDirection=Descending&page=0>
for
more details.

In particular, the updated standard library may have introduced some
undetected bugs. Please report any issues at
http://ironpython.codeplex.com/workitem/list/basic.

Thanks,
IronPython Team

Hi, Dino,

That would fix the problem with recursiveness. But I'd prefer a fix which excludes
the standard library from those warnings, I don't want to swamp our users with useless warnings they can't fix.

Or maybe only trigger the warning on explicit ScriptScope.Compile() calls...

I'll investigate further...

Best regards

"This is still broken. The SimpleXMLTreeBuilder.py module is not included with IronPython. Besides, "fromstring" should work without having to pass SimpleXMLTreeBuilder.TreeBuilder to it, I'm using the same code with both CPython and IronPython.

ATM I'm using ET 1.2.7, with a small patch in ElementIron.py:

....# FIXME: handle settings here? (disable comments, etc)

....# PATCH BEGIN
....from System.Xml import XmlReaderSettings, DtdProcessing
....settings = XmlReaderSettings()
....settings.DtdProcessing = DtdProcessing.Ignore
....# PATCH END
....reader = XmlReader.Create(source, settings)"

ISSUES

1. [New issue] Some path ops are not done through PlatformAdaptationLayer in IronPython.Runtime.Importer
http://ironpython.codeplex.com/workitem/31603
User rickardholmberg has proposed the issue:

"Path name operations in IronPython.Runtime.Importer are supposed to be performed through the PlatformAdaptationLayer, enabling platform adaptations of path name structure. Some operations are still directly done to System.IO.Path, though, which breaks the adaptation layer. The commit https://github.com/rickardraysearch/main/commit/7cc9ed676c1ee6f6f0e770d9c8842d24b4e1c7d6 fixes (at least some of some of) the remaining items."

On behalf of the IronPython, I'm happy to announce the release of IronPython
2.7.1 <http://ironpython.codeplex.com/releases/view/62475>. Like IronPython
2.7 <http://ironpython.codeplex.com/releases/view/54498>, this release

.NET 4 or Silverlight 4.* This release will replace any existing IronPython
installation.

The biggest improvement in IronPython 2.7.1 is support for the unicodedata,
csv, and ats modules. The other Python standard library modules have been
upgraded to match Python 2.7.2.

There has also been a number of bug fixes to make IronPython generally more
compatible with CPython.

Finally, the IronPython Tools for Visual Studio have been deprecated in
favour of the Python Tools for Visual Studio <http://pytools.codeplex.com/>.

See the list of fixed

I'm quite interested in trying out the new PTVS, but i cannot for the life of me figure out how to uninstall the old "IronPython Tools for Visual Studio 1.0". Does anyone have a (relatively simple) step-by-step guide on how to do so?

1. Uninstall IronPython.
2. Reinstall IronPython, but make sure "IronPython Tools for Visual
Studio" is disabled (it is by default in 2.7.1).

You *should* be able to remove it by doing a repair install, but I've
never gotten that to work. The full cycle has always worked for me.

Subject: [Ironpython-users] q: how to configure site-packages folder for
	ironpython/asp.net
Message-ID: <CAOi=b4QOX8+2sq_Cpw5K8sRqWusV-NnDTH4iXcfnq6UKutxPfw@mail.gmail.com>

Hi,

currently i am trying to get a mongo-db running in an asp.net
application written in ironpython. I am trying to use the
python-driver pymongo.

I have installed the modules in the site-packages folder and i am able
to use it in my python25- and also in my ironpython- commandline
interpreter. I can connect to the db and play with it.

But its is not working in my asp.net application. When i fstart the
webform i get following error message:

 Parser Error Message: No module named collections

Here is my test code-behind:

webform.aspx.py--------------------------------------------------------------------------------------------
from pymongo import Connection

def Page_Load(sender, e):
    connection = Connection()

def Button1_Click(sender, e):
    pass
---------------------------------------------------------------------------------------------------------------
In the Global.py I have made following configuration:

def Application_Start():
    ' Code that runs on application startup'
    # if you want to use stdrt-py-libs in yout iron-python app add the folder
    import sys
    sys.path.append('C:\\Python25\\Lib')
    sys.path.append('C:\\Python25\\Lib\\site-packages')


Anyone here who can tell me what's wrong?

And BTW does someone here tried the mongo-db with ipy and the clr-driver?

Thanks much for your help & kind regards

 Bernd

Hi Bruce,

I have not done any WPF myself, but there are a lot of resources on the web:

   - http://www.ironpython.info/index.php/WPF_Example
   - google "ironpython wpf"

I can also recommend "IronPython in Action" book, it has a chapter on WPF.
As for "label1.contents", shouldn't it be "label1.Content" ?

Igor

Subject: [Ironpython-users] Unhandled .Net Exception
Message-ID: <CAD2znaU67DSYLL4PzTWYojjE9z4=C3k0vr3XKKiZ9PPQEsRs-g@mail.gmail.com>

Hello, I was looking at adding a handler for otherwise-uncaught .Net
exceptions, and had found this page:
http://www.ironpython.info/index.php/Handling_Unhandled_Exceptions useful.
However, the code shown falls over where he's trying to get a nicely
formatted python exception here:

    from IronPython.Hosting import PythonEngine
    pyE = PythonEngine()
    print pyE.FormatException(event.Exception)

where I get "ImportError: No module named Hosting". At the bottom he has a
note saying:

"For IronPython 2.0, the code to format the exception from a PythonEngine
is slightly different:

import clr
clr.AddReference('IronPython')
from IronPython.Hosting import PythonEngine
PythonEngine.CurrentEngine.FormatException(someException)

"

which gives me "ImportError: Cannot import name PythonEngine".

I'm using IronPython 2.7.0.40 with .Net 4.0.30319.239. I assume the API has
changed here; can anyone tell me if there is a way to do something like
this FormatException in IronPython 2.7?

Thanks.

This should do it - the hosting APIs changed quite a bit between 2.0 and 2.7:
import clr
clr.AddReference('IronPython')
from IronPython.Runtime import PythonContext
import System
clr.GetCurrentRuntime().GetLanguage(PythonContext).FormatException(System.Exception())

There could be other variations such as using GetLanguageByExtension and not needing to add a ref to IronPython but those will require that the script runtime has the languages properly registered.

Subject: [Ironpython-users] IDNA encoding missing in IPy
Message-ID: <4EAA5FE7.50803@duber.cz>

Hi there everyone,

I'm currently trying to use a new API for a package
written in Python, that uses JSON for its calls.

However, I'm bumping into a problem where IronPython
throws me errors that it's missing a certain encoding
module. Concretely IDNA.

http://docs.python.org/library/codecs.html#module-encodings.idna

Is there anything that can be done in this regard with
IronPython?

Thank you in advance, cheers,

Subject: [Ironpython-users] open xml sdk v2.0
Message-ID: <CA+7con=KJBtr64Wd88_LkikMGOWoMjgU4=bvoRrpR4=60kABHg@mail.gmail.com>

hi,

I am trying to use openxml sdk v2.0 together with python 2.7.1 (was
2.7.0). I have managed to generate the mini document out of the csharp
(http://msdn.microsoft.com/en-us/library/dd440953%28v=office.12%29.aspx)

However if I try to do it from python, the produced document is
corrupted. Word complains about 'parts missing or invalid'. Unzip
spits the following:

$ unzip -t ../foobar.docx
Archive: ?../foobar.docx
? ?testing: word/document.xml
?error: ?invalid compressed data to inflate
? ?testing: _rels/.rels ? ? ? ? ? ? ?OK
At least one error was detected in ../foobar.docx.


Is there some sort of fundamental incompatibility between openxml sdk
and ironpython? Mixed zip libraries?

The test code:

import clr
clr.AddReferenceToFileAndPath("C:\Program Files\Open XML
SDK\V2.0\lib\DocumentFormat.OpenXml.dll")
from DocumentFormat.OpenXml.Packaging import WordprocessingDocument
from DocumentFormat.OpenXml import WordprocessingDocumentType
from DocumentFormat.OpenXml.Wordprocessing import
Text,Paragraph,Run,Document, Body

package = WordprocessingDocument.Create(
'c:/Users/rejap/Desktop/foobar.docx',
WordprocessingDocumentType.Document)
package.AddMainDocumentPart()
package.MainDocumentPart.Document =
Document(Body(Paragraph(Run(Text("""asdfasdfasdfaasdfa""")))))
package.MainDocumentPart.Document.Save()

Subject: [Ironpython-users] Manipulating/Reversing the Ironpython AST
Message-ID: <BAY158-W3365213EAA705C253CECA5B4D30@phx.gbl>


Hi all,
 
I was wondering if IronPython has the ability to reverse/unparse the AST back into a ource file? Or if someone has perhaps built something to do so?
 
Here's what I'm trying to do:
 
I have a game I'm working on, and I'm currently drafting up tools for it. The tools are being written in C# and are meant to make changing and editing game files easier. Several of the game files are written in python and are used to extend objects from the main game source. For instace, I have an Items.py file that contains the following (minimalized for example):
 
from ItemModule import * 
 
import copy 
 
class ScriptedItem(Item): 
    def __init__(self, name, description, itemtypes, primarytype, flags, usability, value, throwpower): 
        Item.__init__(self, name, description, itemtypes, primarytype, flags, usability, value, throwpower, Item.GetNextItemID()) 
    def Clone(self): 
        return copy.deepcopy(self) 
 
ItemLibrary.AddItem(ScriptedItem("Abounding Crystal", "A colourful crystal composed of many smaller crystals. It gives off a warm glow.", ItemType.SynthesisMaterial, ItemType.SynthesisMaterial, 0, ItemUsage.Unusable, 0, 50)) 

In this case, I'd like to provide a convenient front-end to allow editors to modify/add/delete items from the list. To do this, my editor need to be able to:
 

Find and list all the class types (in this example, it'd be only Scripted Item)
Find and list all created items (in this case there'd only be one, Abounding Crystal). I'd need to find the type (in this caseScriptedItem) and all the parameter values
Allow editing of parameters and the creation/removal of items.
 
I tried writing my own parser, but that became increasingly difficult as the complexity of the Item constructors went up. When I found IronPython and its ability to generate a walkable AST, I thought I'd found my solution, and indeed the AST makes it easy to accomplish 1 and 2 of my requirements. However, I'm currently stuck on how to write back changes made in my editor to the source file. My initial idea was to preserve the AST and modify values on the existing nodes for edited items and inject new nodes when new items were created. However even if I could get this to work correctly, I have no idea how to reconvert the AST back into a source file. When I asked on stackoverflow, I was told this is usually done using "prettyprinting" and had some suggestions to use python's "inspect" property.
 
I'm not sure how to use inspect to do what I want, and have some concerns over the amount of effort require to get "prettyprinting" correct, so i wanted to ask if anyone here has written a prettyprinter for ironpython or perhaps knows some other way to accomplish my three goals? Any help would be appreciated,
 
Thanks

If that is the entirety of your solution's requirements, then if I were in your shoes I would just cheat...

I presume ItemModule is a CLR namespace, sourced from an assembly you have loaded via sys.AddReference (or similar technique). In that case, I would create a mock version of that assembly that your tool uses. It would define all of the same interfaces, classes, enums, etc that your script is using from the real one; however the ItemLibrary.AddItem() method would just capture the incoming values for the tool to work with.

The tool would simply host IronPython, load your mocked assembly instead of the real one, create a new ScriptScope, and run the script within it while capturing those incoming values. This would give the tool data to work with, I assume displaying it in some friendly UI format. After making some changes using the UI tool, it should have no problem writing out a new python file that includes the modified parameters / items.

Hack? Yes. But far simpler than dealing with AST and generic code emit.

PTVS's parser (which is just a branch of the IronPython parser) supports this so that we could implement the refactoring features.  The nodes have a ToCodeString method on them which you can call to get back the original code.  You'll need to parse in verbatim mode like so:

            var parser = Parser.CreateParser(
                someTextReader,
                Project.LanguageVersion,
                new ParserOptions() { Verbatim = true, BindReferences = true }
            );
            var ast = parser.ParseFile();

And you'll need to pass the PythonAst that you get back into the ToCodeString as all of the verbatim round-trip info is stored on the top-level Ast node.

This will preserve comments, whitespace, etc...  You can modify the AST in any way you want and still call ToCodeString - the nodes which you insert will all get some default amount of formatting.  You'll want to pass in the original PythonAst that you used to parse the nodes with.  There's some random helper methods like CopyLeadingWhiteSpace and CopyTrailingNewLine on the Node classes for manipulating some of the round trip info - it's not exhaustive, just what we've needed for PTVS's refactoring support.  You can always download the source and add more or contribute back changes if you need some specific additions.

The parser is in Microsoft.PythonTools.Analysis.dll which is a stand-alone DLL (no dependencies on anything outside of the .NET framework).  If you want to get a copy of the DLL you can just download and install PTVS (http://pytools.codeplex.com/) and then the DLL will either be in:

VSINSTALLDIR\Common7\IDE\Extensions\Microsoft\Python Tools for Visual Studio\1.0
                or
%LOCALAPPDATA%\Microsoft\VisualStudio\10.0\Extensions\Microsoft\Python Tools for Visual Studio\1.0

Depending on if you did the default (all-users) install or the per-user install.

The only thing that's possibly missing is that we don't have a good AST re-writer, so you'll need to do that by hand or implement something like the DLR ExpressionVisitor class.
