PEP 523 introduced _PyEval_EvalFrameDefault which inlines PyEval_EvalFrameEx on
non-debug shared builds. This breaks the ability to use py-bt, py-up, and
a few other Python-specific gdb integrations.
This patch fixes the problem by only looking for _PyEval_EvalFrameDefault
frames.
test_gdb passes on both a debug and a non-debug build.
Original patch by Bruno "Polaco" Penteado.
(cherry picked from commit 5fe59f8e3a)
pep 0523 renames PyEval_EvalFrameEx to _PyEval_EvalFrameDefault while the gdb python extension only looks for PyEval_EvalFrameEx to understand if it is dealing with a frame.
Final effect is that attaching gdb to a python3.6 process doesnt resolve python objects. Eg. py-list and py-bt dont work properly.
This patch fixes that. Tested locally on python3.6

* python-gdb.py supports method-wrapper
bpo-29367: python-gdb.py now supports also method-wrapper (wrapperobject)
objects.
(cherry picked from commit 611083331d)
* Update and enhance python-gdb.py
bpo-29259: Detect PyCFunction is the current frame, not only in the
older frame.
Frame.is_other_python_frame() now also handles _PyCFunction_FastCallDict()
frames.
Thanks to the new code to handle fast calls, python-gdb.py is now also able to
detect the <built-in id method of module ...> frame.
Issue #26799: Fix python-gdb.py: don't get once C types when the Python code
is loaded, but get C types on demande. The C types can change if
python-gdb.py is loaded before the Python executable.
Patch written by Thomas Ilsche.
This changes the main documentation, doc strings, source code comments, and a
couple error messages in the test suite. In some cases the word was removed
or edited some other way to fix the grammar.

benchmark files in order to prevent using a random system python, and in
source files of modules which don't provide command line interface. Fixed
shebang lines in the unittestgui and checkpip scripts.

display invalid strings. Such strings can be found while Python is creating a
new string, in a text decoder for example, when Python is compiled in debug
mode.
The gdb hooks for debugging CPython (within Tools/gdb) have
been enhanced to show information on more C frames relevant to CPython within
the "py-bt" and "py-bt-full" commands:
* C frames that are waiting on the GIL
* C frames that are garbage-collecting
* C frames that are due to the invocation of a PyCFunction
the Python traceback if Python is optimized.
* delay the lookup of the size_t type, it is not available at startup
* The second argument of the PyFrameObjectPtr constructor is optional, as
done in other constructors
* iter_builtins() and iter_globals() methods of PyFrameObjectPtr returns
an empty tuple instead of None if Python is optimized
* Fix py-bt and py-bt-full to handle correctly "optimized" frames
* Frame.get_pyop() tries to get the frame pointer from PyEval_EvalCodeEx()
if the pointer is optimized out in PyEval_EvalFrameEx()

Encode unicode strings to the terminal encoding with backslashreplace error (as
Python does for sys.stderr) before writing them to sys.stdout. It fixes
UnicodeEncodeError on writing non-ascii characters in an ascii terminal (C
locale: ASCII encoding).
