Bruno "Polaco" Penteado 2e0f4db114 bpo-30983: eval frame rename in pep 0523 broke gdb's python extension (#2803)
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

Jon Dufresne 3972628de3 bpo-30296 Remove unnecessary tuples, lists, sets, and dicts (#1489)
* Replaced list(<generator expression>) with list comprehension
* Replaced dict(<generator expression>) with dict comprehension
* Replaced set(<list literal>) with set literal
* Replaced builtin func(<list comprehension>) with func(<generator
  expression>) when supported (e.g. any(), all(), tuple(), min(), &
  max())

Victor Stinner fa025f112f Update and enhance python-gdb.py
Issue #29259:

* Detect PyCFunction is the current frame, not only in the older frame
* Ignore PyCFunction_Call() since it now calls _PyCFunction_FastCallDict(), and
  _PyCFunction_FastCallDict() is already detected

Victor Stinner 7fc252adfb Optimize _PyCFunction_FastCallKeywords()
Issue #29259: Write fast path in _PyCFunction_FastCallKeywords() for
METH_FASTCALL, avoid the creation of a temporary dictionary for keyword
arguments.

Cleanup also _PyCFunction_FastCallDict():

* Don't dereference func before checking that it's not NULL
* Move code to raise the "no keyword argument" exception into a new
  no_keyword_error label.

Update python-gdb.py for the change.

Victor Stinner eae64fda5b Issue #28770: Update python-gdb.py for fastcalls
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.

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
