2013-09-19Fix regressions caused by thread-specific breakpoint deletion.Pedro Alves2-1/+6
The recent change to make GDB auto-delete thread-specific breakpoints when the corresponding thread is deleted (https://sourceware.org/ml/gdb-patches/2013-09/msg00038.html) caused gdb.base/nextoverexit.exp to regress. Breakpoint 1, main () at .../gdb/testsuite/gdb.base/nextoverexit.c:21 21 exit (0); (gdb) next [Inferior 1 (process 25208) exited normally] Thread-specific breakpoint -5 deleted - thread 1 is gone. Thread-specific breakpoint -6 deleted - thread 1 is gone. Thread-specific breakpoint -7 deleted - thread 1 is gone. Thread-specific breakpoint 0 deleted - thread 1 is gone. (gdb) FAIL: gdb.base/nextoverexit.exp: next over exit (the program exited) We shouldn't be seeing this for internal or momentary breakpoints. In fact, we shouldn't even be trying to delete them, as whatever created them will take care or it, and therefore it's dangerous to delete them behind the creator's back. I thought it'd still be good to tag thread-specific internal/momentary breakpoints such that we'll no longer try to keep them insert in the target, as they'll cause stops and thread hops in other threads, so I tried disabling them instead. That caused a problem when following a child fork, and detaching from the parent, as we try to reset the step-resume etc. breakpoints to the new child's thread (breakpoint_re_set_thread), after the parent thread is already gone (and the breakpoints are marked disabled). I fixed that by re-enabling internal/momentary breakpoints there, but, that didn't feel super safe either (maybe we'd need a new flag in struct breakpoint instead, to tag the thread-specific breakpoint as "not to be inserted"). It felt like I was heading down a design rat hole, and, other things will usually delete internal/momentary breakpoints soon enough, so I left that little optimization for some other day. So, internal/momentary breakpoints are no longer deleted/disabled at all, and we end up with a one-liner fix.

2013-09-18[Hurd/gnu-nat] Fix old "signal-thread" command regression.Pedro Alves2-3/+9
By inspection, I noticed that when I made the gnu-nat use ptid(pid,0,tid) to represent a thread, instead of using ptid(tid,0,0), in <https://sourceware.org/ml/gdb-patches/2008-08/msg00175.html>, I introduced a bug. The change was: else { - int tid = PIDGET (thread_id_to_pid (atoi (args))); + int tid = ptid_get_tid (thread_id_to_pid (atoi (args))); if (tid < 0) error (_("Thread ID %s not known. Use the \"info threads\" command to\n" "see the IDs of currently known threads."), args); and thread_id_to_pid does: ptid_t thread_id_to_pid (int num) { struct thread_info *thread = find_thread_id (num); if (thread) return thread->ptid; else return pid_to_ptid (-1); } (pid_to_ptid (-1) is the same as minus_one_ptid.) So before, we were really looking at the pid, where thread_id_to_pid stores the -1. The right fix is to compare the whole ptid to minus_one_ptid, of course. Completely untested, but I think it's obvious enough, so I went ahead and put it in. gdb/ 2013-09-18 Pedro Alves <palves@redhat.com> * gnu-nat.c (set_sig_thread_cmd): Compare the thread's ptid to minus_one_ptid instead of looking at the ptid's tid field and comparing that to -1.

2013-09-17PR gdb/11568 - delete thread-specific breakpoints on thread exitPedro Alves5-0/+208
PR gdb/11568 is about thread-specific breakpoints being left behind when the corresponding thread exits. Currently: (gdb) b start thread 2 Breakpoint 3 at 0x400614: file thread-specific-bp.c, line 23. (gdb) b end Breakpoint 4 at 0x40061f: file thread-specific-bp.c, line 29. (gdb) c Continuing.

There's no way that breakpoint can trigger again (*), so the PR argues that the breakpoint should just be removed, like local watchpoints. I'm ambivalent on this -- it could be reasonable to disable the breakpoint (kind of like breakpoint in shared library code when the DSO is unloaded), so the user could still use it as visual template for creating other breakpoints (copy/paste command lists, etc.), or we could have a way to change to which thread a breakpoint applies. But, several people pushed this direction, and I don't plan on arguing... (*) - actually, there is ... thread numbers are reset on "run", so the user could do "break foo thread 2", "run", and expect the breakpoint to hit again on the second thread. But given gdb's thread numbering can't really be stable, that'd only work sufficiently well for thread 1, so we'd better call it unsupported. So with the patch, whenever a thread is deleted from GDB's list, GDB goes through the thread-specific breakpoints and deletes corresponding breakpoints. Since this is user-visible, GDB prints out: Thread-specific breakpoint 3 deleted - thread 2 is gone. And of course, we end up with: (gdb) info breakpoints Num Type Disp Enb Address What 2 breakpoint keep y 0x0000000000400614 in start at thread-specific-bp.c:23 breakpoint already hit 1 time 4 breakpoint keep y 0x000000000040061f in end at thread-specific-bp.c:29 breakpoint already hit 1 time 2013-09-17 Muhammad Waqas <mwaqas@codesourcery.com> Pedro Alves <palves@redhat.com> PR gdb/11568 * breakpoint.c (remove_threaded_breakpoints): New function.

Now the call in question, from within thread.c:print_thread_info, does pass in LOCATION as print_what, but print_stack_frame doesn't have the same check print_frame_info has. We could consider adding it, but setting these globals depending on print_what isn't very clean, IMO. What we have is two logically distinct operations mixed in the same function(s): #1 - print frame, in the format specified by {print_what, print_level and print_args}. #2 - We're displaying a frame to the user, and I want the default sal to point here, because the program stopped here, or the user did some context-changing command (up, down, etc.). So I added a new parameter to print_stack_frame & friends for point #2, and went through all calls in the tree adjusting as necessary.

<https://sourceware.org/ml/gdb-patches/2013-09/msg00301.html> <https://sourceware.org/ml/gdb-patches/2013-09/msg00383.html> This patch adds a new convenience function called $_isvoid, whose only purpose is to check whether an expression is void or not. This became necessary because the new convenience variable $_exitsignal (not yet approved) has a mutual exclusive behavior with $_exitcode, i.e., when one is "defined" (i.e., non-void), the other is cleared (i.e., becomes void). Doug wanted a way to identify which variable to use, and checking for voidness is the obvious solution. It is worth mentioning that my first attempt, after a conversation with Doug, was to actually implement a new $_isdefined() convenience function. I would do that (for convenience variables) by calling lookup_only_internalvar. However, I found a few problems: - Whenever I called $_isdefined ($variable), $variable became defined (with a void value), and $_isdefined always returned true. - Then, I tried to implement $_isdefined ("variable"), and do the "$" + "variable" inside GDB, thus making it impossible for GDB to create the convenience variable. However, it was hard to extract the string without having to mess with values and their idiossincrasies. Therefore, I decided to abandon this attempt (specially because I didn't want to spend too much time struggling with it). Anyway, after talking to Doug again we decided that it would be easier to implement $_isvoid, and this will probably help in cases like <http://stackoverflow.com/questions/3744554/testing-if-a-gdb-convenience-variable-is-defined>. I wrote a NEWS entry for it, and some new lines on the documentation. gdb/ 2013-09-16 Sergio Durigan Junior <sergiodj@redhat.com> * NEWS: Mention new convenience function $_isvoid. * value.c (isvoid_internal_fn): New function.

New regexpr now correctly deals with trailing canonical pathname.
