Subject: [Python.NET] surveying the landscape ...
Message-ID: <CALxxJLTgQZ1Z-ZA8asFD3oAKEzTAYHrjQDM7qd8uEJmjcGkF2A@mail.gmail.com>

Hi David,

Can you please give access to pythonnet on Test PyPI to me?

https://testpypi.python.org/pypi/pythonnet

For example 3 people have access to production PyPI installation:

https://pypi.python.org/pypi/pythonnet/2.2.0.dev1

Thanks,
Denis

Subject: [Python.NET] Adding new attributes to .Net classes is unstable
Message-ID: <AM3PR05MB07909D75657C12DD84E35465EBB70@AM3PR05MB0790.eurprd05.prod.outlook.com>

Hi,

I have a problem with adding attributes to .Net classes being unstable. E.g.

from System import TimeSpan

TimeSpan.my_method = lambda self: self.TotalMinutes
ts = TimeSpan.FromHours(1)
ts.my_method()

This code will sometimes work and other times fail with the exception 'TimeSpan' object has no attribute 'my_method'.

The failure rate is variable and for some scripts/program it will work all the time while for others it will not work at all. It seems to fail a lot more often on Python 3.5 than on Python 3.4.

If I look at either dir(ts) or ts.__class__.__dict__ the method is there even when the call to my_method fails.

I have tried to look into the PythonNet code for clues, but as far as I can see the new attribute is registered by MetaType. tp_setattro without error, but the method is still not found.

What I want to ask you is


1.       Is adding new attributes to a .Net class supported behaviour or does it work more or less by accident?

2.       Any pointers to how the attribute lookup is handled for .Net classes is appreciated. Currently I have not found if and where PythonNet is involved in the actual attribute lookup process.

Cheers,

?ystein Idema Torget

I purchased the book for 160 USD with discount and it is now available to
first 50 pythonnet contributors, who reply to me:

https://thehackerguidetopython.com/

The book is available in all major e-book formats: PDF, MOBI, EPUB and also
online.

You can get a sense of the book from the author's blog:
