Thanks Jan.
Here's a fix, test included. Comments?
Thanks,
Pedro Alves
--------------------------
[PATCH] gdb/17347 - Regression: GDB stopped on run with attached process
Doing:
gdb --pid=PID -ex run
Results in GDB getting a SIGTTIN, and thus ending stopped. That's
usually indicative of a missing target_terminal_ours call.
E.g., from the PR:
$ sleep 1h & p=$!; sleep 0.1; gdb -batch sleep $p -ex run
[1] 28263
[1] Killed sleep 1h
[2]+ Stopped gdb -batch sleep $p -ex run
The workaround is doing:
gdb -ex "attach $PID" -ex "run"
instead of
gdb [-p] $PID -ex "run"
With the former, gdb waits for the attach command to complete before
moving on to the "run" command, because the interpreter is in sync
mode at this point, within execute_command. But for the latter,
attach_command is called directly from captured_main, and thus misses
that waiting. IOW, "run" is running before the attach continuation
has run, before the program stops and attach completes. The broken
terminal settings are just one symptom of that. Any command that
queries or requires input results in the same.
The fix is to wait in catch_command_errors (which is specific to
main.c nowadays), just like we wait in execute_command.

While I do not fully understand why that happens in every run of that Fedora

I find it understandable and the Fedora testsuite issues does get fixed by the

Unrelated to this patch - this patch only moved the code. Also the code move
could be a separate patch:
I do not see why the testsuite commonly uses "exec sleep" while it also uses
"sleep" itself which also works fine.

Hi,
when I tried to use --with-babeltrace on Fedora Rawhide x86_64
using gcc-4.9.1-3.fc22.x86_64 I got:

cc1: all warnings being treated as errors

configure: failed program was:
The patch below fixes it for me.
In configure.ac there is above this check:
# Append -Werror to CFLAGS so that configure can catch the warning
# "assignment from incompatible pointer type", which is related to
# the babeltrace change from 1.0.3 to 1.1.0. Babeltrace 1.1.0 works
# in GDB, while babeltrace 1.0.3 is broken.
# AC_LIB_HAVE_LINKFLAGS may modify CPPFLAGS in it, so it should be
# safe to save and restore CFLAGS here.
saved_CFLAGS=$CFLAGS
CFLAGS="$CFLAGS -Werror"
Maybe it would be easier to use there:
CFLAGS="$CFLAGS -Werror -Wno-unused-variable"
But maybe -Werror is cross-compiler compatible while -Wno-unused-variable is
not, I have no idea.

Fixed. To be precise, >= 1.1.2 rejects the faked packet, 1.1.1
doesn't. See the table I posted.

In order to check libbabeltrace's behaviour in configure, we have to write
a c program to generate CTF data and read the trace data via
babeltrace or any program (using libbabeltrace) written by ourselves.
It is not easy to do so.
The patch is updated. OK to apply?

Subject: [PATCH] Check babeltrace 1.1.0
Subject: [PATCH] Check babeltrace 1.1.0
When GDB uses recent version of babeltrace, such as 1.2.x, we'll see
such error emitted from babeltrace library,
(gdb) target ctf .../gdb/testsuite/gdb.trace/actions.ctf
[error] Invalid CTF stream: content size is smaller than
packet headers.
[error] Stream index creation error.
[error] Open file stream error.
The problem can be reproduce out of GDB too, using babeltrace,
$ babeltrace ./fake-packet.ctf/
[error] Invalid CTF stream: content size is smaller than packet headers.
[error] Stream index creation error.
[error] Open file stream error.
Recent babeltrace library becomes more strict on CTF, and complains
about one "faked packet" GDB adds, when saving trace data in ctf
format from GDB. babeltrace 1.1.0 has a bug that it can't read trace
data smaller than a certain size (see https://bugs.lttng.org/issues/450).
We workaround it in GDB to append some meaningless data in a faked
packet to make sure trace file is large enough (see ctf.c:ctf_end).
The babeltrace issue was fixed in 1.1.1 release. However, babeltrace
recent release (since 1.1.2) starts to complain about such faked
packet. Here is a table shows that whether faked packet or no faked
packet is supported by various babeltrace releases,
faked packet no faked packet
1.1.0 Yes No
1.1.1 Yes Yes
1.1.2 No Yes
1.2.0 No Yes
We decide to include the code to workaround 1.1.0 issue only if 1.1.0
is used. We choose pkg-config to check babeltrace's version in
configure.
gdb:
2014-08-20 Yao Qi <yao@codesourcery.com>
* configure.ac: Disable babeltrace support if pkg-config is
missing. Use pkg-config to check whether libbabeltrace is
1.1.0.
* config.in: Regenerate.
* configure: Regenerate.
* ctf.c (CTF_FILE_MIN_SIZE): Remove.
(ctf_end): Wrap the code with
#if HAVE_LIBBABELTRACE1_1_0 #endif.
[HAVE_LIBBABELTRACE1_1_0] (CTF_FILE_MIN_SIZE): New macro.

Subject: [patch+7.8?] Fix crash on Python frame filters with unreadable arg
--d6Gm4EdcadzBjdND

Hi,
https://bugzilla.redhat.com/show_bug.cgi?id=1126177
ERROR: AddressSanitizer: SEGV on unknown address 0x000000000050 (pc 0x000000992bef sp 0x7ffff9039530 bp 0x7ffff9039540 T0)
#0 0x992bee in value_type .../gdb/value.c:925
#1 0x87c951 in py_print_single_arg python/py-framefilter.c:445
#2 0x87cfae in enumerate_args python/py-framefilter.c:596
#3 0x87e0b0 in py_print_args python/py-framefilter.c:968
It crashes because frame_arg::val is documented it may contain NULL
(frame_arg::error is then non-NULL) but the code does not handle it.
Another bug is that py_print_single_arg() calls goto out of its TRY_CATCH
which messes up GDB cleanup chain crashing GDB later.
I tried to somehow separate it to two patches first but it in the end kept
them merged.
No regressions on {x86_64,x86_64-m32,i686}-fedorarawhide-linux-gnu.
It is probably 7.7 regression (I have not verified it) due to the introduction
of Python frame filters.
I am not sure if it is more suitable for gdb.arch/ or gdb.python/ , used the
latter.
Thanks,
Jan
