Subject: [Python.NET] several questions: Q1 is it ok if I fold in several
	changes
Message-ID: <4B5E192C.3090805@sandia.gov>

As soon as I can figure out how to use svn and https from work (or as 
soon as I give up and do the following from home) my hope is to...

- download the latest and greatest, which I suspect is not a lot 
different than 2.0 alpha2
- fold in Feihon Hsu's patch that fixes 2.0 alpha2 for .net 2.0 SP1
- fold in the "Python26 -> PYTHON26" fix mentioned a bit ago
- run a test or two, commit the changes, and make a 2.0 alpha3 that 
includes setup.py, if I can figure out how to post such a file on 
sourceforge (I appear to still be a developer; thanks

Would anyone have a problem with that?  If people point me to any other 
fixes I'll include those too, please don't spam the list with redundant 
information on bug fixes, though, spam me out of band.

Subject: [Python.NET] Q2: py.net problems w/python 2.6.2
Message-ID: <4B5E2BC4.8090801@sandia.gov>

Could anyone conveniently try python.net with python 2.6.2?  I am seeing 
two fatal problems in my lightly-patched python.net.

I'm using ubuntu 9.04
python 2.6.2
python.net 2.0 alpha2 with Borzenkov's suggested PYTHON25 -> PYTHON26 
changes and Feihong Hsu's changes
mono 2.0.1 (this is the what mono --version says, which I think is 
packaged as distribution 1.9.something?)

For all of this I'm using the python.exe that gets built alongside 
python.net, because ubuntu's python environments are irritatingly built 
with --disable-shared

Here are the problems:

If I try the following:
 >>> import clr
 >>> import System
 >>> STR = System.String('hithere')

I get a fatal error "GCHandle value belongs to a different domain"... 
this is being thrown by the coercion of an IntPtr to a GCHandle, from 
within the coercion operation in ManagedType.GetManagedObject.

If however I try the following:
 >>> import clr
 >>> from System.Drawing import Point
 >>> p = Point(5,5)

then I can
 >>> p.X
5
 >>> p.Y
5
 >>> p.ToString()
u'{X=5,Y=5}'
 >>> dir(p)
['Add', 'Ceiling', ..., '__class__', ...]

No problem, right? Wrong:
 >>> p.__class__
dies in the most awful way, dumping all thread stacks and killing mono 
and python.  I get a message saying "Got a SIGSEGV while executing 
native code.  etc."

If anyone has any clues about this, I'd love to hear them.  My current 
plan is to install python 2.5.x as an alternate python, rebuild against 
that, and see if that works, and then perhaps dig into this further.  I 
might also try 2.6.4 since someone on the list recently asserted they 
had it working with that.

thanks,
hamilton

I might be able to find time to test on windows tomorrow.  Remind me
if you haven't heard.

I'm currently running Python.NET in Python 2.6.2 on Windows for a few 
weeks. I tried your sample code, and everything works fine. I'm not 
using Mono though, but regular Microsoft .NET.

I had a few issues at the beginning, as my (patched) version of 
Python.NET was not up to date with the Python.NET trunk. My vendor 
branch tells me I updated from Python.NET rev.98 to rev.101 and my 
problems went away (for now).

HTH,
Nicolas.
