-Subject: [PATCH] Fix Python3.9 related runtime problems
-
-Python3.9b1 is now available on Rawhide.  GDB w/ Python 3.9 support
-can be built using the configure switch -with-python=/usr/bin/python3.9.
-
-Attempting to run gdb/Python3.9 segfaults on startup:
-
-    #0  0x00007ffff7b0582c in PyEval_ReleaseLock () from /lib64/libpython3.9.so.1.0
-    #1  0x000000000069ccbf in do_start_initialization ()

-    #3  0x00000000007afb0a in initialize_all_files () at init.c:237
-    ...
-
-Consulting the the documentation...
-
-https://docs.python.org/3/c-api/init.html
-
-...we find that PyEval_ReleaseLock() has been deprecated since version
-3.2.  It recommends using PyEval_SaveThread or PyEval_ReleaseThread()
-instead.  In do_start_initialization, in gdb/python/python.c, we
-can replace the calls to PyThreadState_Swap() and PyEval_ReleaseLock()
-with a single call to PyEval_SaveThread.   (Thanks to Keith Seitz
-for working this out.)
-
-With that in place, GDB gets a little bit further.  It still dies
-on startup, but the backtrace is different:
-

-We checked with some Python Developers and were told that we should
-acquire the GIL prior to calling any Python C API function.  We
-definitely don't have the GIL for calls of PyOS_InterruptOccurred().
-
-I moved class_gdbpy_gil earlier in the file and use it in
-gdbpy_check_quit_flag() to acquire (and automatically release) the
-GIL.
-
-With those changes in place, I was able to run to a GDB prompt.  But,
-when trying to quit, it segfaulted again due to due to some other
-problems with gdbpy_check_quit_flag():
-
-    Thread 1 "gdb" received signal SIGSEGV, Segmentation fault.

-
-In this case, we're trying to call a Python C API function after
-Py_Finalize() has been called from finalize_python().  I made
-finalize_python set gdb_python_initialized to false and then cause
-check_quit_flag() to return early when it's false.
-
-With these changes in place, GDB seems to be working again with
-Python3.9b1.  I think it likely that there are other problems lurking.
-I wouldn't be surprised to find that there are other calls into Python
-where we don't first make sure that we have the GIL.  Further changes
-may well be needed.
-
-I see no regressions testing on Rawhide using a GDB built with the
-default Python version (3.8.3) versus one built using Python 3.9b1.
-
-I've also tested on Fedora 28, 29, 30, 31, and 32 (all x86_64) using
-the default (though updated) system installed versions of Python on
-those OSes.  This means that I've tested against Python versions
-2.7.15, 2.7.17, 2.7.18, 3.7.7, 3.8.2, and 3.8.3.  In each case GDB
-still builds without problem and shows no regressions after applying
-this patch.

-gdb/ChangeLog:
-
-2020-MM-DD  Kevin Buettner  <kevinb@redhat.com>
-	    Keith Seitz  <keiths@redhat.com>
-
-	* python/python.c (do_start_initialization): For Python 3.9 and
-	later, call PyEval_SaveThread instead of PyEval_ReleaseLock.
-	(class gdbpy_gil): Move to earlier in file.
-	(finalize_python): Set gdb_python_initialized.
-	(gdbpy_check_quit_flag): Acquire GIL via gdbpy_gil.  Return early
-	when not initialized.
