| | | | | | | | | | | | | | | | | | | | | | This fixes PR python/15816. The bug here is that python-selftest.exp can fail: No symbol "RETURN_MASK_ALL" in current context. RETURN_MASK_ALL is a macro, so if macros do not end up in the debuginfo (very typical) then the test fails. It seemed simplest to me to simply turn the RETURN_MASK_ defines into enum constants. This way they end up in the debuginfo and all is well. PR python/15816: * exceptions.h (return_mask): Now an enum. (RETURN_MASK_QUIT, RETURN_MASK_ERROR, RETURN_MASK_ALL): Now enum constants.

* move gdbarch object from objfile to per-BFDTom Tromey2013-08-2010-21/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the "gdbarch" field from the objfile into the BFD. This field's value is derived from the BFD and is immutable over the lifetime of the BFD. This makes it a reasonable candidate for pushing into the per-BFD object. This is part of the long-term objfile splitting project. In the long run I think this patch will make it simpler to moves types from the objfile to the per-BFD object; but the patch makes sense as a minor cleanup by itself.

* linux-nat.c: no need to block child signals so aggressively.Pedro Alves2013-08-192-45/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In http://sourceware.org/ml/gdb-patches/2013-08/msg00174.html , the issue of child signal handling around ptrace option support discovery being different between GDB and GDBserver came up. I recalled adding these block_child_signals calls, and the "We don't want those ptrace calls to be interrupted" comment, but not exactly why. So I looked into it. My first guess is that I got confused. The patch that added this <http://sourceware.org/ml/gdb-patches/2009-04/msg00125.html> rewrote the linux native async support completely, and the old async support code had the SIGCHLD handler itself do waitpid, so in places that we'd want a blocking waitpid, we'd have to have the signal handler blocked. That was probably the mindset I had at the time. Anyway, whatever the case, looks like I was wrong on the need for this blocking. Given GDBserver doesn't block like this, I investigated why this is currently needed on GDB but not on GDBserver. I removed the block_child_signals (and restore) calls, and hacked linux-nat.c to call linux_test_for_tracefork in a loop, like: @@ -534,7 +534,10 @@ static int linux_supports_tracefork (int pid) { if (linux_supports_tracefork_flag == -1) - linux_test_for_tracefork (pid); + { + while (1) + linux_test_for_tracefork (pid); + } return linux_supports_tracefork_flag; } Running the resulting GDB, I then saw bad things happening. Specifically, I'd end up with a bunch of zombies, and eventually, the machine would refuse to spawn new processes, claming insufficient resources. The issue is that linux_test_for_tracefork test forks, and has the child fork again. If we don't block SIGCHLD on entry to the function, the children will inherit SIGCHLD's action/disposition (meaning, SIGCHLD will be unblocked in the child). When the first child forks again a second child, and that child exits, the first child gets a SIGCHLD. Now, when we try to wrap up for the whole options test, we kill the first child, and collect the waitstatus. Here, when SIGCHLD isn't blocked, GDB will first see the child reporting a stop with SIGCHLD. gdbserver's ptrace options test does a PTRACE_KILL loop at the end, which catches the SIGCHLD, and retries the kill. The GDB version did not do that. So the GDB version would proceed, leaving the child zombie (until GDB exists), as nothing collected its final waitstatus. So this patch makes the GDB version of linux_test_for_tracefork do the exact same as the GDBserver version, removes all this unnecessary blocking throughout, and adds a couple comments at places that do need it -- namely: places where we'll use sleep with sigsuspend; and linux_async_pipe, as that destroys the pipe the signal handler touches. Tested on x86_64 Fedora 17, sync and async. gdb/ 2013-08-19 Pedro Alves <palves@redhat.com> * linux-nat.c (linux_test_for_tracefork) (linux_test_for_tracesysgood, linux_child_follow_fork) (lin_lwp_attach_lwp, linux_nat_resume): Don't block child signals.

* src-release: Strip "-cvs" from GDB source dir and tarball.Joel Brobecker2013-08-172-1/+6
| | | | | | | | | | | | | | | The nightly snapshots we have been creating in the past did not include the "-cvs" suffix at the end of the version number. Snapshot packaging started breaking ever since GDB switched to using BFD's version number. Things got partially fixed with the previous change to this file, but the change missed the fact that the "-cvs" suffix in the tarball name (Eg: gdb-7.6.50-20130816-cvs.tar) is undesirable. This patch removes it. ChangeLog: * src-release (VER): When using $(TOOL)/common/create-version.sh, strip the "-cvs" suffix from the version number if present.

| | | | | | | | | | | | | | | | | This moves a few static variables from thread-info functions into remote_state. Pedro said on irc that these functions implement the ancient thread-discovery method and that he wouldn't be surprised if they had rotted; nevertheless it seems safer to me to make them explicitly per-remote.
