+ * The point of this program is to crash in a multi-threaded app.

+ * * Spinning inside a signal handler
+ * * Spinning inside a signal handler executing on the altstack
+ * * In a syscall
+ * * In a syscall inside a signal handler
+ * * In a syscall inside a signal handler executing on the altstack
+ * * Finally, the main thread crashes in main, with no frills.
+ *
+ * These are the things threads in JRockit tend to be doing. If gdb

Subject: gdb-6.5-bz185337-resolve-tls-without-debuginfo-v2.patch
;; Support TLS symbols (+`errno' suggestion if no pthread is found) (BZ 185337).
;;=push+jan: It should be replaced by Infinity project.
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=185337
2008-02-24 Jan Kratochvil <jan.kratochvil@redhat.com>
Port to GDB-6.8pre.
currently for trivial nonthreaded helloworld with no debug info up to -ggdb2 you
will get:
(gdb) p errno
[some error]
* with -ggdb2 and less "errno" in fact does not exist anywhere as it was
compiled to "(*__errno_location ())" and the macro definition is not present.
Unfortunately gdb will find the TLS symbol and it will try to access it but
as the program has been compiled without -lpthread the TLS base register
(%gs on i386) is not setup and it will result in:
Cannot access memory at address 0x8
Attached suggestion patch how to deal with the most common "errno" symbol
for the most common under-ggdb3 compiled programs.
Original patch hooked into target_translate_tls_address. But its inferior
call invalidates `struct frame *' in the callers - RH BZ 690908.

While thinking about it overriding some GDB _commands_ was not my intention.
There is a general assumption if I have a shell COMMAND and some FILE I can do
$ COMMAND FILE
and COMMAND will appropriately load the FILE.
FSF GDB currently needs to specify also the executable file for core files
which already inhibits this intuitive expectation. OTOH with the build-id
locating patch which could allow such intuitive start notneeding the
executable file. Still it currently did not work due to the required "-c":
$ COMMAND -c COREFILE
Entering "file", "core-file" or "attach" commands is already explicit enough
so that it IMO should do what the command name says without any
autodetections. The second command line argument
(captured_main->pid_or_core_arg) is also autodetected (for PID or CORE) but
neither "attach" accepts a core file nor "core-file" accepts a PID.
The patch makes sense only with the build-id patchset so this is not submit
for FSF GDB inclusion yet. I am fine with your patch (+/- Hui Zhu's pending
bfd_check_format_matches) as the patch below is its natural extension.
Sorry for the delay,

Subject:
gdb-6.6-buildid-locate-misleading-warning-missing-debuginfo-rhbz981154.patch
;; Fix 'gdb gives highly misleading error when debuginfo pkg is present,
;; but not corresponding binary pkg' (RH BZ 981154).
;;=push+jan
Comments by Sergio Durigan Junior <sergiodj@redhat.com>:
This is the fix for RH BZ #981154
It is mainly a testcase addition, but a minor fix in the gdb/build-id.c
file was also needed.
gdb/build-id.c was added by:
commit dc294be54c96414035eed7d53dafdea0a6f31a72
Author: Tom Tromey <tromey@redhat.com>
Date: Tue Oct 8 19:56:15 2013 +0000
and had a little thinko there. The variable 'filename' needs to be set to
NULL after it is free'd, otherwise the code below thinks that it is still
valid and doesn't print the necessary warning ("Try: yum install ...").

Subject: gdb-6.8-quit-never-aborts.patch
;; Make the GDB quit processing non-abortable to cleanup everything properly.
;;=fedora: It was useful only after gdb-6.8-attach-signalled-detach-stopped.patch .
We may abort the process of detaching threads with multiple SIGINTs - which are
being sent during a testcase terminating its child GDB.
Some of the threads may not be properly PTRACE_DETACHed which hurts if they
should have been detached with SIGSTOP (as they are accidentally left running
on the debugger termination).

;; Print reasons for failed attach/spawn incl. SELinux deny_ptrace (BZ 786878).
;;=push+jan
http://sourceware.org/ml/gdb-patches/2012-03/msg00171.html
Hi,
and here is the last bit for new SELinux 'deny_ptrace':
https://bugzilla.redhat.com/show_bug.cgi?id=786878
As even PTRACE_TRACEME fails in such case it needs to install hook for even
that event.
Thanks,
Jan

* common/linux-ptrace.c [HAVE_SELINUX_SELINUX_H]: include
selinux/selinux.h.
(linux_ptrace_attach_warnings): Call linux_ptrace_create_warnings.
(linux_ptrace_create_warnings): New.
* common/linux-ptrace.h (linux_ptrace_create_warnings): New declaration.
* config.in: Regenerate.
* configure: Regenerate.
* configure.ac: Check selinux/selinux.h and the selinux library.
* inf-ptrace.c (inf_ptrace_me): Check the ptrace result.
* linux-nat.c (linux_nat_create_inferior): New variable ex. Wrap
to_create_inferior into TRY_CATCH, call linux_ptrace_create_warnings.
gdb/gdbserver/
* config.in: Regenerate.
* configure: Regenerate.
* configure.ac: Check selinux/selinux.h and the selinux library.
* linux-low.c (linux_traceme): New function.
(linux_create_inferior, linux_tracefork_child): Call it instead of
direct ptrace.

http://sourceware.org/ml/gdb-patches/2015-10/msg00301.html
Hi,
in some cases with deleted main executable GDB will want to kill the inferior.
$ cp /bin/sleep /tmp/sleep;/tmp/sleep 1h&p=$!
$ rm /tmp/sleep
$ gdb /tmp/sleep $p
GNU gdb (GDB) 7.10.50.20151016-cvs
/tmp/sleep: No such file or directory.
Attaching to process 9694
/tmp/sleep (deleted): No such file or directory.
A program is being debugged already. Kill it? (y or n) _
The first attachment of "/tmp/sleep" commandline argument errors at:
267 if (scratch_chan < 0)
268 perror_with_name (filename);
1051 if (catch_command_errors_const (exec_file_attach, execarg,
1052 !batch_flag))
Then GDB tries to attach to the process $p:
1082 if (catch_command_errors (attach_command, pid_or_core_arg,
1083 !batch_flag) == 0)
This succeeds and since this moment GDB has a valid inferior. But despite that
the lines
1082 if (catch_command_errors (attach_command, pid_or_core_arg,
1083 !batch_flag) == 0)
still fail because consequently attach_command() fails to find the associated
executable file:
267 if (scratch_chan < 0)

Subject: gdb-bz533176-fortran-omp-step.patch
;; Fix stepping with OMP parallel Fortran sections (BZ 533176).
;;=push+jan: It requires some better DWARF annotations.
https://bugzilla.redhat.com/show_bug.cgi?id=533176#c4
I find it a bug in DWARF and gdb behaves correctly according to it. From the
current DWARF's point of view the is a function call which you skip by "next".
If you hide any /usr/lib/debug such as using:
gdb -nx -ex 'set debug-file-directory /qwe' -ex 'file ./tpcommon_gfortran44'
and use "step" command instead of "next" there it will work.
(You need to hide debuginfo from libgomp as you would step into libgomp sources
to maintain the threads for execution.)
There should be some DWARF extension for it, currently tried to detect
substring ".omp_fn." as this function is called "MAIN__.omp_fn.0" and do not
consider such sub-function as a skippable by "next".
Another problem is that with "set scheduler-locking" being "off" (default
upstream) or "step" (default in F/RHEL) the simultaneous execution of the
threads is inconvenient. Setting it to "on" will lockup the debugging as the
threads need to get synchronized at some point. This is a more general
debugging problem of GOMP outside of the scope of this Bug.

;; Display Fortran strings in backtraces.
;;=fedoratest
http://sourceware.org/ml/gdb-patches/2014-07/msg00709.html
Hi,
for Fortran it fixes displaying normal strings also in frames/backtraces:
(gdb) frame
->
The patch is simple and I do not see why it should not be this way.
For C/C++ TYPE_CODE_STRING is not used. I am not aware of Pascal but that
language is currently not really much supported in GDB anyway.
This was a part of my archer/jankratochvil/vla branch but it is not a part of
the Intel VLA patchset as it in fact is completely unrelated to "VLA".
No regressions on {x86_64,x86_64-m32,i686}-fedora22pre-linux-gnu.
Thanks,
Jan

Hi,
PR 16581:
GDB crash on inherit_abstract_dies infinite recursion
https://sourceware.org/bugzilla/show_bug.cgi?id=16581
fixed crash from an infinite recursion. But in rare cases the new code can
now gdb_assert() due to weird DWARF file.
I do not yet fully understand why the DWARF is as it is but just GDB should
never crash due to invalid DWARF anyway. The "invalid" DWARF I see only in
Fedora GCC build, not in FSF GCC build, more info at:
https://bugzilla.redhat.com/show_bug.cgi?id=1069382
http://people.redhat.com/jkratoch/gcc-debuginfo-4.8.2-7.fc20.x86_64-gnatbind.debug
Thanks,
Jan

.SH NAME
gstack \- print a stack trace of a running process
.SH SYNOPSIS
.B gstack
pid
.SH DESCRIPTION
\f3gstack\f1 attaches to the active process named by the \f3pid\f1 on
the command line, and prints out an execution stack trace. If ELF
symbols exist in the binary (usually the case unless you have run
strip(1)), then symbolic addresses are printed as well.
If the process is part of a thread group, then \f3gstack\f1 will print
out a stack trace for each of the threads in the group.

Date: Fri, 27 Oct 2017 21:07:50 +0200
Subject: gdb-rhbz1007614-memleak-infpy_read_memory-test.patch
;; Fix 'memory leak in infpy_read_memory()' (RH BZ 1007614)
;;=fedoratest
Original message by Tom Tromey:
<https://sourceware.org/ml/gdb-patches/2012-03/msg00955.html>
Message-ID: <871uoc1va3.fsf@fleche.redhat.com>
Comment from Sergio Durigan Junior:
In order to correctly test this patch, I wrote a testcase based on Jan
Kratochvil's <gdb/testsuite/gdb.base/gcore-excessive-memory.exp>. The
testcase, which can be seen below, tests GDB in order to see if the
amount of memory being leaked is minimal, as requested in the bugzilla.
It is hard to define what "minimum" is, so I ran the testcase on all
supported RHEL architectures and came up with an average.
commit cc0265cdda9dc7e8665e8bfcf5b4477489daf27c
Author: Tom Tromey <tromey@redhat.com>
Date: Wed Mar 28 17:38:08 2012 +0000
* python/py-inferior.c (infpy_read_memory): Remove cleanups and
explicitly free 'buffer' on exit paths. Decref 'membuf_object'
before returning.

Subject: gdb-rhbz1084404-ppc64-s390x-wrong-prologue-skip-O2-g-3of3.patch
;; Fix '[ppc64] and [s390x] wrong prologue skip on -O2 -g code' (Jan
;; Kratochvil, RH BZ 1084404).
;;=fedoratest
These testcases have been created by compiling glibc-2.17-78 on
RHEL-7.1 s390x/ppc64 boxes, and then taking the "select.o" file
present at $builddir/misc/select.o.

Subject: gdb-rhbz1149205-catch-syscall-after-fork-test.patch
;; Fix '`catch syscall' doesn't work for parent after `fork' is called'
;; (Philippe Waroquiers, RH BZ 1149205).
;;=fedoratest
URL: <https://sourceware.org/ml/gdb-patches/2013-05/msg00364.html>
Message-ID: <1368136582.30058.7.camel@soleil>
From: Philippe Waroquiers <philippe dot waroquiers at skynet dot be>
To: gdb-patches at sourceware dot org
Subject: RFA: fix gdb_assert caused by 'catch signal ...' and fork
Date: Thu, 09 May 2013 23:56:22 +0200
The attached patch fixes a gdb_assert caused by the combination of catch
signal and fork:
break-catch-sig.c:152: internal-error: signal_catchpoint_remove_location: Assertion `signal_catch_counts[iter] > 0' failed.
The problem is that the signal_catch_counts is decremented by detach_breakpoints.
The fix consists in not detaching breakpoint locations of type bp_loc_other.
The patch introduces a new test.
Comments by Sergio Durigan Junior:
I addded a specific testcase for this patch, which tests exactly the
issue that the customer is facing. This patch does not solve the
whole problem of catching a syscall and forking (for more details,
see <https://sourceware.org/bugzilla/show_bug.cgi?id=13457>,
specifically comment #3), but it solves the issue reported by the
customer.
I also removed the original testcase of this patch, because it
relied on "catch signal", which is a command that is not implemented
in this version of GDB.

Date: Fri, 27 Oct 2017 21:07:50 +0200
Subject: gdb-rhbz1186476-internal-error-unqualified-name-re-set-test.patch
;; Fix 'backport GDB 7.4 fix to RHEL 6.6 GDB' [Original Sourceware bug
;; description: 'C++ (and objc): Internal error on unqualified name
;; re-set', PR 11657] (RH BZ 1186476).
;;=fedoratest
Comments from Sergio Durigan Junior:
The "proper" fix for this whole problem would be to backport the
"ambiguous linespec" patch series. However, it is really not
recommended to do that for RHEL GDB, because the patch series is too
big and could introduce unwanted regressions. Instead, what we
chose to do was to replace the gdb_assert call by a warning (which
allows the user to continue the debugging session), and tell the
user that, although more than one location was found for his/her
breakpoint, only one will be used.

| ^~~~~~~~~~~~~~~~~~
Information about the deprecated function can be found here:
https://docs.python.org/3.9/whatsnew/3.9.html#deprecated
Specifically, with regard to PyEval_InitThreads(), it says:
The PyEval_InitThreads() and PyEval_ThreadsInitialized() functions
are now deprecated and will be removed in Python 3.11. Calling
PyEval_InitThreads() now does nothing. The GIL is initialized by
Py_Initialize() since Python 3.7. (Contributed by Victor Stinner
in bpo-39877.)
I chose to disable the call with a #if test using PY_VERSION_HEX.
There is precedent for use of PY_VERSION_HEX; it's used in two places
in python-internal.h. I noticed that under certain circumstances
python-internal.h defines PyEval_InitThreads to be nothing, which
accomplishes the same thing. I considered doing something similar for
this case, but decided against it because, at some point in the future,
the presence of PyEval_InitThreads() without some explanation will be
confusing to a reader who won't be able to find PyEval_InitThreads in
the current (future for us) Python API. IMO, use of the #if along
with an accompanying comment seemed more straightforward.

* python/python.c (do_start_initialization): Don't call
PyEval_InitThreads for Python 3.9 and beyond.

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

#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.

#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.

Subject: [PATCH] Make '{putchar,fputc}_unfiltered' use 'fputs_unfiltered'
There is currently a regression when using
'{putchar,fputc}_unfiltered' with 'puts_unfiltered' which was
introduced by one of the commits that reworked the unfiltered print
code.
The regression makes it impossible to use '{putchar,fputc}_unfiltered'
with 'puts_unfiltered', because the former writes directly to the
ui_file stream using 'stream->write', while the latter uses a buffered
mechanism (see 'wrap_buffer') and delays the printing.
If you do a quick & dirty hack on e.g. top.c:show_gdb_datadir:

Note how the '>' was printed before the output, and "TEST" and "PUTS"
were printed together.
My first attempt to fix this was to always call 'flush_wrap_buffer' at
the end of 'fputs_maybe_filtered', since it seemed to me that the
function should always print what was requested. But I wasn't sure
this was the right thing to do, so I talked to Tom on IRC and he gave
me another, simpler idea: make '{putchar,fputc}_unfiltered' call into
the already existing 'fputs_unfiltered' function.
This patch implements the idea. I regtested it on the Buildbot, and
no regressions were detected.

/usr/lib/gcc/x86_64-redhat-linux/4.6.1/../../../../lib64/Scrt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
=> Change the order for overrides.
One has to also use -fPIC rather than -fPIE, -fPIC is stronger.
The correct way would be:
make check//unix RUNTESTFLAGS='CC_FOR_TARGET=gcc\ -fPIC\ -pie CXX_FOR_TARGET=g++\ -fPIC\ -pie solib-display.exp'
But there is a problem with testsuite.unix non-unique subdir name and also
a problem with make -j parallelization of the testsuite.

but this has caused a different regression (as discussed in the confcall).
QUICK_ADDRMAP is built only from .debug_aranges. But we can have existing
built .debug_aranges for CUs in OBJFILE but still some CUs do not need to have
DWARF at all while they can feature CFIs (.eh_frame or .debug_frame).
It has been described by Daniel Jacobowitz at:
Re: [2/4] RFC: check psymtabs_addrmap before reading FDEs
http://sourceware.org/ml/gdb-patches/2010-07/msg00012.html
Sorry for this regression by me (in that fix of a different regression).
Fixed it the "slow way" as this branch is now obsoleted by .gdb-index.
No regressions on {x86_64,x86_64-m32,i686}-fedora13-linux-gnu.
Checked-in.
Thanks,
Jan
