Subject: [PATCH] use <asm/sgidefs.h>
Build fix for MIPS with musl libc
The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
but not by musl. Regardless of the libc, the kernel headers provide
<asm/sgidefs.h> which provides the same definitions, so use that
instead.

MIME-Version: 1.0

As for strace [1], when <sys/reg.h> is included after <linux/ptrace.h>,
the build fails on m68k with the following diagnostics:
In file included from ./../nat/linux-ptrace.h:28:0,
from linux-low.h:27,
from linux-m68k-low.c:20:

In file included from linux-m68k-low.c:27:0:

^
Fix this by moving <sys/reg.h> on top of "linux-low.h".

Subject: [PATCH] nat/fork-inferior: include linux-ptrace.h
To decide whether fork() or vfork() should be used, fork-inferior.c
uses the following test:
#if !(defined(__UCLIBC__) && defined(HAS_NOMMU))
However, HAS_NOMMU is never defined, because it gets defined in
linux-ptrace.h, which is not included by fork-inferior.c. Due to this,
gdbserver fails to build on noMMU architectures. This commit fixes
that by simply including linux-ptrace.h.
This bug was introduced by commit
2090129c36c7e582943b7d300968d19b46160d84 ("Share fork_inferior et al
with gdbserver"). Indeed, the same fork()/vfork() selection was done,
but in another file where linux-ptrace.h was included.
Fixes the following build issue:
../nat/fork-inferior.c: In function 'pid_t fork_inferior(const char*, const string&, char**, void (*)(), void (*)(int), void (*)(), const char*, void (*)(const char*, char* const*, char* const*))':
../nat/fork-inferior.c:376:11: error: 'fork' was not declared in this scope
pid = fork ();
^~~~
../nat/fork-inferior.c:376:11: note: suggested alternative: 'vfork'
pid = fork ();
^~~~
vfork

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 ()

at worktree-test1/gdb/python/python.c:1877
#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:
#0 0x00007ffff7b04306 in PyOS_InterruptOccurred ()

...
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.
0x00007ffff7bbab0c in new_threadstate () from /lib64/libpython3.9.so.1.0

#3 gdbpy_check_quit_flag (extlang=<optimized out>)
at worktree-test1/gdb/python/python.c:278
#4 0x0000000000576e96 in check_quit_flag ()
at worktree-test1/gdb/extension.c:776
#5 0x000000000057700c in restore_active_ext_lang (previous=0xe9c050)

#6 0x000000000088913a in do_my_cleanups (

at worktree-test1/gdbsupport/cleanups.cc:131
#7 do_final_cleanups ()
at worktree-test1/gdbsupport/cleanups.cc:143
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.
