Do not run test_gdb when gdb embeds Python 2. (GH-31956) 2022-03-17 18:00:56 +09:00

bpo-46600: Fix test_gdb.test_pycfunction() for clang -Og (GH-31058)
Fix test_gdb.test_pycfunction() for Python built with clang -Og.
Tolerate inlined functions in the gdb traceback.

When _testcapimodule.c is built by clang -Og, _null_to_none() is
inlined in meth_varargs() and so gdb returns _null_to_none() as
the frame #1. If it's not inlined, meth_varargs() is the frame #1.

bpo-45256: Avoid C calls for most Python to Python calls. (GH-28937)
* Avoid making C calls for most calls to Python functions.

* Change initialize_locals(steal=true) and _PyTuple_FromArraySteal to consume the argument references regardless of whether they succeed or fail.

Ths commit inlines calls to Python functions in the eval loop and steals all the arguments in the call from the caller for

bpo-44032: Move data stack to thread from FrameObject. (GH-26076)
* Remove 'zombie' frames. We won't need them once we are allocating fixed-size frames.

* Add co_nlocalplus field to code object to avoid recomputing size of locals + frees + cells.

* Move locals, cells and freevars out of frame object into separate memory buffer.

* Use per-threadstate allocated memory chunks for local variables.

* Move globals and builtins from frame object to per-thread stack.

* Move (slow) locals frame object to per-thread stack.

* Move internal frame functions to internal header.

The GDB provided by HPE on HP-UX contains a modified version string. Therefore
the tests fail. Adapt the regex to match that string.

bpo-37362: test_gdb now ignores stderr (GH-14287)
test_gdb no longer fails if it gets an "unexpected" message on
stderr: it now ignores stderr. The purpose of test_gdb is to test
that python-gdb.py commands work as expected, not to test gdb.

test_gdb.test_pycfunction: test more calling conventions (GH-13668)
As the code paths for various METH_* conventions are diverging due
to optimizations, we should check they continue to be covered by
GDB integration.

bpo-36974: Fix GDB integration (GH-13665)
As it changes the way functions are called, the PEP 590 implementation
skipped the functions that the GDB integration is looking for
(by name) to find function calls.

Looking for the new helper `cfunction_call_varargs` hopefully fixes the
tests, and thus buildbots.

The changed frame nuber in test_gdb is due to there being fewer
C calls when calling a built-in method.

bpo-32962: Fix test_gdb failure in debug build with -mcet -fcf-protection -O0 (GH-9656)
When Python is built with the intel control-flow protection flags,
-mcet -fcf-protection, gdb is not able to read the stack without
actually jumping inside the function. This means an extra
'next' command is required to make the $pc (program counter)
enter the function and make the stack of the function exposed to gdb.

Elvis Pranskevichus 7279b5125e bpo-34537: Fix test_gdb:test_strings with LC_ALL=C (GH-9483)
We cannot simply call locale.getpreferredencoding() here,
as GDB might have been linked against a different version
of Python with a different encoding and coercion policy
with respect to PEP 538 and PEP 540.

Thanks to Victor Stinner for a hint on how to fix this.

bpo-34007: Skip traceback tests if the Program Counter is not available. (GH-9018)
Sometimes some versions of the shared libraries that are part of the
traceback are compiled in optimised mode and the Program Counter (PC)
is not present, not allowing gdb to walk the frames back. When this
happens, the Python bindings of gdb raise an exception, making the
test impossible to succeed.
