commit 5b9dc340a30678b048497308b266b1b1c4b995da
Author: Marvin Humphrey <[email protected]>
Date: 2016-01-21T00:25:02Z
Use Python refcounting.
In our Python bindings, Clownfish objects are Python objects, so use
Python's refcounting.
commit 7e81bd9cc46ab5f0a019c4304beb6c205c95e06c
Author: Marvin Humphrey <[email protected]>
Date: 2016-01-22T23:40:08Z
Implement Clownfish exceptions using `longjmp`.
Though Python uses exceptions, executing exceptions from the Python C
API requires setting thread-local error information and indicating an
error condition to the Python interpreter by returning NULL from the
glue function. So Clownfish has to have its own independent exception
handling.

Author: Marvin Humphrey <[email protected]>
Date: 2016-01-23T00:51:01Z
Re-raise Python exceptions from Clownfish.
Add a function which takes the Python `sys.exc_info`, wraps it in a
Clownfish Err, and THROWs it.

Add ParseTuple-compatible converters for numerics.
Add some conversion functions which conform to the API specified by
Python's ParseTuple C functionality.

Add wrappers for `To_Host` in Python bindings.
Add NULL-safe wrappers, one of which is refcount neutral.
commit c29a47ae2655586ad8744c32957eba199f8a7727
Author: Marvin Humphrey <[email protected]>

`To_Host` for Python returns incref'd self.
The default implementation for `To_Host` for Python just returns the
result of calling INCREF on the invocant.

To_Host for composite types to Python.
Implement To_Host conversion for Hash -> Python dict and Vector ->
Python list.

Implement scalar types To_Host for Python.
- String -> string
- Blob -> bytes
- Boolean -> bool
- Integer -> int
- Float -> float
commit 1a8fb6c7d49a1dd6a680704009bf079cb2c534e9
Author: Marvin Humphrey <[email protected]>

Prepare to trap errors in Python glue code.
Add `CFBind_run_trapped`, which is designed to wrap Clownfish
C routines and trap errors. This will be used inside glue code for
Python, either returning a Python object or setting `sys.exc_info` and
returning NULL per the Python C API.

Author: Marvin Humphrey <[email protected]>
Date: 2016-01-28T02:23:36Z
Add helper routines for Python callbacks.
The generated C code for calling back into Python from Clownfish when a
method is overridden will require these helper functions for running the
Python callable, converting return values, etc.

Gen OVERRIDE callbacks for Python.
Generate the C functions which call back into Python from
Clownfish-flavored C when a method is overridden.
