Fix a crash when a generator is created in a C thread that is destroyed while
the generator is still used. The issue was that a generator contains a frame,
and the frame kept a reference to the Python state of the destroyed C thread.
The crash occurs when a trace function is setup.
- rename to _test_structmembersType to avoid the class being automatically
called by test_capi
- allow space for trailing NUL in inplace_member field of all_structmembers
- use T_STRING_INPLACE instead of T_INPLACE_STRING as keyword argument
to _test_structmembersType initializer
- don't attempt to initialize inplace_member field if T_STRING_INPLACE
argument wasn't supplied.
Most uses of PyCode_New found by http://www.google.com/codesearch?q=PyCode_New
are trying to build an empty code object, usually to put it in a dummy frame
object. This patch adds a PyCode_NewEmpty wrapper which lets the user specify
just the filename, function name, and first line number, instead of also
requiring lots of code internals.
sizeof(Py_UNICODE) == 2, PyUnicode_FromWideChar now converts
each character outside the BMP to the appropriate surrogate pair.
Thanks Victor Stinner for the patch.
