Subject: [Ironpython-users] Enable Unmanaged Debugging IronPython
Message-ID: <CAOO38k3T5X1qYrs5SkwPGS_tQcOvB-YzgS9YYHUPcS=Pp7+L9g@mail.gmail.com>

Hello,

While debugging, with an IronPython startup project, I'm trying to step
from IronPython to C# code to unmanaged C/C++ code.  Is this possible?

I am currently able to step from IronPython to C# when the startup project
is IronPython.  I'm also currently able to step from C# to unmanaged C/C++
code when the startup project is C#.  However, I am not able to step from
IronPython to C# to C++ when the startup project is IronPython.

Even though there was no relevant gui option I could find, I tried edited
the .pyproj file, changing the EnableUnmanagedDebugging field from "false"
to "true", but this did not have any noticeable impact.

I'm using Visual Studio 2010 and Microsoft Visual Studio 2010 (Version
10.0.40219.1 SP1Rel), Microsoft .NET Framework Version 4.5.50709 SP1Rel,
and Python Tools for Visual Studio 2.1.20620.00.

I would greatly appreciate any help in this, even if just to confirm it is
not possible so that I stop trying.

Regards,
John

Adding DinoV because this sounds more like a PTVS issue than an IronPython
issue - from the IronPython side there's nothing that should prevent it
from working AFAIK. IronPython in VS uses the normal managed debugger.

Dino,

Did you ever have a chance to look into this many moons ago, and if not,
any tips on how to go about figuring it out? I'm pretty sure I am running
into something similar.

Thanks,

Alex

Subject: [Ironpython-users] Recreate and compile a script in an existing
	engine instance?
Message-ID: <620E6490461DDB44942EB371DFAEA70A56224D51@EXCH01.nu-ins.local>

In C# I?m loading and compiling a script like this:-

            _engine = Python.CreateEngine();
            _scope = _engine.CreateScope();

            _scriptSource = _engine.CreateScriptSourceFromFile(filename, Encoding.UTF7, SourceCodeKind.Statements);
            _compiledScript = _scriptSource.Compile();

(At some point in time my application will run the script by calling _compiledScript.Execute(_scope).)

I?ve also got a FileSystemWatcher watching the script file. When the file changes I recreate the ScriptSource and compile, basically executing those last two lines again. When I do this, _scriptSource.Compile() throws an ArgumentException (?Invalid argument valueParameter name: start?). The stack trace is below. It works if I re-create *everything* ? the engine, scope, script source, compile, but this seems a bit a wasteful. Am I missing something?

Stack trace:-

Message-ID: <CO1MSDNADMCDS2V6xlm00015092@discussions.codeplex.com>

Hi ironpython,

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

In today's digest:ISSUES

1. [New issue] IronPython throw InsufficientMemoryException when using numpy in threads
2. [New issue] support for running content of zip file

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

ISSUES

1. [New issue] IronPython throw InsufficientMemoryException when using numpy in threads
http://ironpython.codeplex.com/workitem/35378
User elishao has proposed the issue:

"I have some IronPython code that being called from within a C# application.
This code worked fine until I decided to change one function to run in a thread.
when numpy functions called in a python thread a InsufficientMemoryException exception is thrown.
I Searched for solutions but didn't find. can someone explain why it is happening and how can I fix it?

I think this is happening only when I have two threads that use numpy

I run code like this:

C#:
_python.functionA(); # _python was created with "Python.CreateEngine()"
_python.functionA(); # twice on purpose


Python:
import threading
import time
import numpy

def blah():    
    print numpy.array([100,100,0])

def functionA():
    t = threading.Timer(0,blah)    
    t.start()
    time.sleep(2)


And I got this Exception:
Exception in thread Thread-1:
Traceback (most recent call last):
  File "c:\Program Files\IronPython 2.7.1\Lib\threading.py", line 552, in _Thread__bootstrap_inner
    self.run()
  File "c:\Program Files\IronPython 2.7.1\Lib\threading.py", line 756, in run
    self.function(*self.args, **self.kwargs)
  File "C:\workspace\my_python_script.py", line 113, in blah
    print numpy.array([100,100,0])
MemoryError: Exception of type 'System.InsufficientMemoryException' was thrown.


This is on Windows 7. 32bit. 4G RAM. quad core."-----------------

2. [New issue] support for running content of zip file
http://ironpython.codeplex.com/workitem/35379
User paweljasinski has proposed the issue:

"This is cpython vs. ironpython difference, which is used by script option of distlib
$ cat __main__.py
print __file__
print __name__

$ zip aaa.zip __main__.py
  adding: __main__.py (deflated 20%)

$ python aaa.zip
aaa.zip/__main__.py
__main__

$ ipy aaa.zip
  File "aaa.zip", line
SyntaxError: Non-ASCII character '\xb8' in file aaa.zip on line 1, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details
"

Subject: [Ironpython-users] Recreate and compile a script in an existing

Just as a side question out of curiosity: Are you really using UTF7 encoding? Are you constrained to ASCII?

Smells like a bug, because this should work. Can you open an issue (

I think I?ve found the cause of the problem. I recreate the script source and compile it within the FileSystemWatcher.Changed event. I can only assume that the file is still locked or is still being written to as this event fires - adding even a very small Thread.Sleep() seems to have fixed it.

Hi, Andrew,

According to my experiences, the FileSystemWatcher are only of limited use without additional precautions.

They fire "eventually" after a file modification took place (the write access happened). This does not imply that

1.     The modifying program has finished its modifications ? it could be still issuing further write requests to complete its work.

2.     The modifying program has closed the file handle. (By default, windows blocks concurrent access to the files.)

3.     No one else has started modifying the file in the meantime (including the next "cycle of the original modifying program).

Most of the time, one wishes some "Notify me when the modifying program has closed the file handle, and atomically give me a file handle" event.

Best regards

In regards to https://ironpython.codeplex.com/workitem/31764, I was
wondering how you got the heap dump like you posted. I'm looking into this
issue because I'm having some memory leak type issues as well and would
like to try and fix this.

Hi, Slide,

As written in the 3rd comment, the heapdump was generated using ClrProfiler:
https://clrprofiler.codeplex.com/releases/view/97738

I was using an older version, it seems (before .NET 4.5 came out).

I had various mileage using different memory profilers while trying to debug this problem. Some profilers did not show any useful information (just displaying "root" holding references to some Ironpython stuff), others did crash (including ClrProfiler).

Somehow, I tracked it to some pinned objects, but got stuck then, due to lacking knowledge of IronPython and DLR internas.

We even tried to find commercial support / contractors back then to solve this problem, to no avail. (https://mail.python.org/pipermail/ironpython-users/2012-October/016273.html and some private emails to companies like Xamarin.)

Eventually, we had internal workarounds for most of the problems caused by this, and the problem was scheduled low priority.

So thanks a lot for your efforts, and good luck! Should you solve the problems, I'll invite you for a pizza and beer should we ever meet in real. ?

Best regards

I believe that tries to use expat under the covers and IronPython doesn't
support expat. It's a native module in CPython, and there is no
implementation in IronPython. You can try the implementation from FePy, but
it is very old, so it may not run out of the box, you may need to modify it
to get it to work (and it doesn't implement everything in pyexpat).

If it's using the generic SAX parser it shouldn't be trying to use expat,
but I think that workaround was only added in 2.7.4. Try using a newer
version of IronPython and see if that helps.

Hi ironpython,

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

In today's digest:ISSUES

1. [New issue] Telnetlib exception - "getaddrinfo returns an empty list"

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

ISSUES

1. [New issue] Telnetlib exception - "getaddrinfo returns an empty list"
http://ironpython.codeplex.com/workitem/35388
User cemremengu has proposed the issue:

"I am trying to port a native python script into an IronPython project. The script gathers data from a list of IPs with telnet. The native version works perfectly fine however the IronPython version keeps giving me an exception saying "getaddrinfo returns an empty list".

I am almost sure that this is because the IP is unreachable but the native version is able to handle the situation by telling me that the connection to the specified IP has timed out. I tried many ways to catch the exception but for some reason nothing catches it.

I am thinking that this may be a bug but it may be also the case that I am simply doing something wrong."

Subject: [Ironpython-users] test framework
Message-ID: <CA+7conn9_posUbGgf_EDJGh1UJR9LEGSGiv+ezAczkSmVcHwWQ@mail.gmail.com>

First of all, there is a need to document where the tests are and how
to run them. It took me a moment to figure it out, so it make sense to
share it.

The test config: IronLanguages/Test/IronPython.tests
An individual test can be started by: ./test-ipy.cmd /test:test_zipimport_cpy

I remember at one time compiling TestRunner.
IronLanguages/Test/TestRunner/TestRunner.sln, so if something doesn't
work, try to build it.

The body of the tests is located in many places:
IronLanguages/Languages/IronPython/Tests
IronLanguages/External.LCA_RESTRICTED/Languages/IronPython/27/Lib/test


In addition to ./test-ipy.cmd the test from stdlib can be run with a usual:
ipy -X:FullFrames -m unittest test.test_zipimport_support

I also had 'nose' running at some point, so it is likely to be still ok.


Now the second part, what is not so nice about our test framework and
perhaps how can we avoid the same mistakes in "3".

As Jeff refers to it: "fabulously complicated test infrastructure"
(FCTI?), is a bit of inconvenient to use. I suspect the definition of
what individual test constitutes is not uniform. FCTI things a test is
entire file or even worse a package. I found no way to test a single
function out of a test file without reconfiguring or modifying a lot.

For example:
test_stdconsole.py takes ~3 minutes. But a test where it fails 12 seconds.
so I nuke (or comment out) all other test functions in
test_stdconsole.py to get to fast test cycle.

Second example:
modules_io_related_ipy is a single test, but it includes not only all
functions out of a file but entire package (all files out of
IronLanguages/Languages/IronPython/Tests/modules/io_related). Here I
basically remove all not interesting files and functions.

If anybody has a better way, please share.

Thanks for writing this down! It could go on the github wiki as well, but
at least search engines are likely to find it.

Yep. It's a legacy of the system used at MS (which I believe was called
SNAP); the current TestRunner was the simplest thing Dino could put
together to get it working when the code was permanently moved out of MS.

My thinking on testing for 3 can be found at
https://github.com/jdhardy/ironpython3/commits/test-runner.

The main reason I want to use NUnit (or xUnit.Net) to drive it is that they
support multiple platforms, and it saves us having to write test runners
everywhere (keeping in mind things like Android, iOS, Win8, etc.). Doing
so, though, involves rewriting the discovery portions of both iptest and
the CPython test suite, but at least we only have to do it once. Then the
tests can be exposed to any NUnit-capable runner.

Nothing to help much in the short term, but longer term things will get
better.

Subject: [Ironpython-users] Adoption of IronPython
Message-ID: <CA+7conmraD4Bs8iUJdf0iTUVzjCZsUP4Ct3VM2PFNpnEC1s7Yw@mail.gmail.com>

Recently I had 2 ideas or perhaps suggestions which may help
IronPython to get better.
I asked myself, what would help us to get more general python packages
to get IP specific patches and keep things alive. Most of them use
travis as a test framework and cover most of the python versions,
including pypy, under linux. So what is stopping us from testing the
package under IronPython? Travis does not have windows support.

So the idea 1, help good people of github to get windows support for travis.
Or if you prefer, get mono in shape so it can be used as test
environment for IP under linux.

Second observation from porting exercise of bytes vs. chars vs.
unicode. Every package keeps its own platform.py or similar which
deals with 2.x/3.x differences. After n-th package, I thought "if
there was one package for all to deal with it, someone could update it
to handle not only 2.x and 3.x but also ip2.x". Guess what, there is
already a package which does it and it appears to be used by a few
projects. It is six.

The idea 2, check what can be done about our notorious encode problem
with help of six.

Hi ironpython,

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

ISSUES

1. [New issue] Exceptions not being trapped by Debugger in VS 2013
http://ironpython.codeplex.com/workitem/35389
User johntrinder has proposed the issue:

"I've installed the FePy tools package (2.0) for Visual Studio 2013 and have encountered a minor bug which doesn't occur in VS2012:

If an exception is thrown during program execution the debugger should put the cursor straight in the line in the appropriate script and display a popup giving details of the exception; instead nothing happens other than the traceback report in the console window. Debugging otherwise works brilliantly.

It works fine in VS 2012 though.

The same happens with the latest beta releases (1 and 2)"

I noticed this while working on virtualenv. They run tests on CPython and
PyPy but not Jython or IronPython. Making sure IP is part of their
regression suites is important, but the burden falls on us to get it setup
(which is fair IMO).

One of my goals for the B3 -> RC 2.7.5 release is much better Mono support.
I'm going to restrict myself to working on my Mac and see what happens (and
then try it in an Ubuntu VM just to double check). Supporting it on travis
could get some of the key projects that drive adoption.

Also a good idea. If six-ified libraries also work on IronPython, that's a
big win for us. There's another, similar library whose name escapes me
right now.

The third thing (and the hardest) is that IronPython needs better docs.
Ideally we'd have a copy of the Python stdlib docs that called out
compatibility issues, and also guides on how to embed IronPython, which is
a critical use case.

For now, that's probably the best place. Eventually I'd like to use
something like CPython's sphinx docs, but the wiki is a good start.

What do you mean 'save off assemblies'? I looked at 'ipy -h' as you 
suggested but couldn't find anything of ehlp. I tried 'ipy -O file.py' 
but no optimised file (file.pyo) was generated.
Thanks for the response btw.

[Re] IronPython doesn't support pyc files. There is a way to save off 
assemblies, if you run ipy with -h it should tell you how.

Nope - nothing under -X remotely like it! In fact I can't see any 
options for saving anything.

[Re] Should be an option -X:SaveAssemblies or something like that. 
IronPython doesn't support pyo files either. Both pyc and pyo files 
require support for Python bytecode, which IronPython does not have 
right now.

Message-ID: <CA+=eR5Gu3x97sOePD3S_sVD1DCHjb2jtBv5VSa_md3imqUYx6A@mail.gmail.com>

Hi everyone,

I am trying to port a native python script into an IronPython project. The
script gathers data from a list of IPs with telnet. The native version
works perfectly fine however the IronPython version keeps giving me an
exception saying "getaddrinfo returns an empty list".

I am almost sure that this is because the IP is unreachable (which in fact
is) but the native (python) version is able to handle the situation by
telling me that the connection to the specified IP has timed out. I tried
many ways to catch the exception but for some reason it can not be handled.

I am thinking that this may be a bug but it may be also the case that I am
simply doing something wrong. Any ideas ?

*Complete Exception Message:*

An exception of type 'System.Exception' occurred in
Snippets.debug.scripting but was not handled in user code

Additional information: getaddrinfo returns an empty list

Are you talking about Visual Studio or the IronPython console? AFAICT the
console already does both of those. For Visual Studio, you'll have to ask
the PTVS team (http://pytools.codeplex.com).

Subject: [Ironpython-users] problem incorporating namespace into Xaml
Message-ID: <53D19A7C.7050708@dsl.pipex.com>

I'm new to FePy and after doing a fair bit of studying am embarking on 
transcoding a C# project to FePy. I'm encountering a problem 
incorporating a module that defines a subclass of Canvas and then trying 
to utilize this custom canvas in the Xaml code.

My skeleton files/modules and contents are as follows:

_*module1.py

*_import clr
clr.AddReference('PresentationFramework')
import System.Windows.Controls as swc

class CustomCanvas(swc.Canvas):
     def __init__(self):
         pass_*

*__*WpfApplication1.xaml*_

<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
*xmlns:local="clr-namespace:module1"*
        Title="WpfApplication1" Height="300" Width="300">
        <Grid>
*<local:CustomCanvas HorizontalAlignment="Left" Height="100" 
Margin="96,90,0,0" VerticalAlignment="Top" Width="100"/>*
        </Grid>
</Window>

_*WpfApplication1.py*_

import wpf

from System.Windows import Application, Window

class MyWindow(Window):
     def __init__(self):
         wpf.LoadComponent(self, 'WpfApplication1.xaml')

Application().Run(MyWindow())


I've marked in bold where I have incorporated my module/namespace. 
Intellisense says that on the *<local:CustomCanvas .../>* line, 
CustomCanvas 'does not exist in the namespace *"clr-namespace:module1"'*
I'm guessing that it's not possible to do (yet) what I want to do - 
which is pretty basic.
Thanks in advance btw for any advice and tips.

Just so you are aware FePy was the name of a side project that was a set of
enhancements to IronPython. If you are looking for a shorter form of
IronPython, IP is generally the best way to go so there is no confusion.

I'm no WPF expert, but I'm guessing the issue is that IronPython doesn't
statically build a "real" .NET class, and the namespace and class name
aren't guaranteed to be the same on each run.*

It is possible to manipulate the type generation using __clrtype__[1] but
it's not well documented. That allows you to control the exact type name
that is used so that other code can look it up using reflection.

I have grand plans for how this will in IronPython, where classes can take
keyword args and there are function attributes to set types:

  class CustomCanvas(swc.Canvas, namespace="Foo"):
      pass

Then you could use *xmlns:local="clr-namespace:Foo" *and it would work as
expected. That's still a ways out, though - I'd have to implement support
for those keyword args first. :)

- Jeff

[1] http://ironpython.net/documentation/dotnet/dotnet.html#clrtype

* In your case, the backing type name would be something like
"IronPython.Types.System.Windows.Controls.Canvas$1" - and it's the "$1"
that can change on each run.

Repeating my (minority) argument on this subject years ago:

"IP" is generally used as the acronym for "Internet Protocol" and is so 
generally understood with that meaning, that re-use of that acronym for 
any other computer-related concept is fraught with misunderstanding.

A more appropriate short form for IronPython would be: "IPy".

Except that is nearly exactly the form that IPython uses as their logo [1].
Maybe IronPy (or IronPython) is short enough. Some James's don't want to be
called "Jim" :)

ISSUES

1. [New issue] DependencyProperty implementation in IP?
http://ironpython.codeplex.com/workitem/35425
User johntrinder has proposed the issue:

"I'm new to IP and am trying to get to grips with the DependencyProperty class implementation (if there is one). I'm new to setting up a DependencyProperty anyway and I'm beginning a learning curve involving them. I have an excellent C# VS project that uses it and am analysing it also.

Could someone please tell me if I'm wasting my time using IP to learn about DependencyProperty - I've Googled it and have got the basics but it's all in C# and can't find anything for IP. I'm becoming enamoured with IP and so would like to stick with this."
