Add better support for conversion to native Python types in public API

Moritz Beutel — Thu, 26 Sep 2013 18:15:27 -0000

The attached patch improves support for converting managed values (reference or boxed values) to the corresponding Python types.

This support had previously been partly implemented in Converter.ToPython() but it was not exposed in the public interface of PyObject (if I'm not mistaken), which made it hard for me to call Python functions from managed code in an embedding scenario. My patch makes the following changes:

adds PyObject.FromManagedValue() which tries to convert a given managed object to an appropriate builtin Python type
adds Converter.ToPythonValue() which does the same thing as Converter.ToPython() except that it converts managed arrays to Python lists where appropriate

Being not very familiar with the Python for .NET codebase, I didn't have the heart to build my array support directly into Converter.ToPython(). However I'd be happy if the array handling code could go to Converter.ToPython() in order to avoid having two similarly-named functions (.ToPython() and .ToPythonValue()) which differ in a non-obvious way, so if that is considered appropriate, please move it there.

Backslash In TestDottedName SetUp Fails on OSX

The patch attached to this uses System.IO.Path.DirectorySeparatorChar to build the path correctly to the PyImportTest module.

Mono (2.8.1) on Ubuntu 10.10 throws on Type.GetMethod

Mono (2.8.1) on Ubuntu 10.10 throws on Type.GetMethod("Invoke")
when the method doesn't exist. This was the case when the ClassManager tried to create a DelegateObject in response to
type.IsSubclassOf(dtype) where dtype = typeof(System.Delegate)

pyansistring.cs added it to the Python.Runtime namespace

Barton Cline — Sun, 30 Jan 2011 09:42:31 -0000

* pystring.cs claims:
/// <summary>
/// Represents a Python (ansi) string object. See the documentation at
/// http://www.python.org/doc/current/api/stringObjects.html for details.
/// </summary>
So why in the world does the string constructor call PyUnicode_FromUnicode()???

* User contribution pyansistring.cs didn't build. I added it to the namespace with the using System reference.

Incref the ConstructorBinding before return

Barton Cline — Mon, 24 Jan 2011 09:01:10 -0000

Re-enable the Incref() call on ConstructorBinding.tp_descr_get()
For now, it seems, the sole reason for the Descriptor __get__ is to return AN INCREF()ed reference to the wrapped instance.

Select Type Constructs using Type.Overloads[]

Barton Cline — Mon, 10 Jan 2011 06:03:48 -0000

Implements the .Overloads[PyOrCsType, ...] syntax on class objects as described in the docs. __overloads__[...] is a valid alias in the sort term, but deprecation is planned for the near future. It works very much like MethodObject __overloads__ (which was also aliased as "Overloads" in an earlier update). These new names support the current state of IronPython.

When used like a property .Overloads returns a __doc__-like string from its __repr__ method.
GetItem() returns a bound constructor that also has a pretty cool __repr__ method.

unittest test_ClrAddReference update

Barton Cline — Mon, 03 Jan 2011 05:02:03 -0000

test_module.test_ClrAddReference() now expects an assembly instead of a python module (like my branch does).

Convert.ToPrimitive() uses Marshal.Copy() for unicode chrs

Barton Cline — Mon, 03 Jan 2011 02:45:20 -0000

In Convert.ToPrimitive(), Marshal the newly created unicode buffer pointer as a character array because the cast
result = (char)Marshal.ReadInt16(op);
throws an OverflowException on negative numbers.
