2015-11-30Remote thread create/exit eventsPedro Alves2-1/+12
When testing with "maint set target-non-stop on", a few threading-related tests expose an issue that requires new RSP packets. Say there are 3 threads running, 1-3. If GDB tries to stop thread 1, 2 and 3, and then waits for their stops, but meanwhile say, thread 2 exits, GDB hangs forever waiting for a stop for thread 2 that won't ever happen. This patch fixes the issue by adding support for thread exit events to the protocol. However, we don't want these always enabled, as they're useless most of the time, and would slow down remote debugging. So I made it so that GDB can enable/disable them, and then made gdb do that around the cases that need it, which currently is only infrun.c:stop_all_threads. In turn, if we have thread exit events, then the extra "thread x exited" traffic slows down attach-many-short-lived-threads.exp enough that gdb has trouble keeping up with new threads that are spawned while gdb tries to stop existing ones. To fix that I added support for the counterpart thread created events too. Enabling those when we try to stop threads ensures that new threads never get a chance to themselves start new threads, killing the race. gdb/doc/ChangeLog: 2015-11-30 Pedro Alves <palves@redhat.com> * gdb.texinfo (Remote Configuration): List "set/show remote thread-events" command in configuration table.

2015-08-06gdbserver: Fix non-stop / fork / step-over issuesPedro Alves1-1/+4
Ref: https://sourceware.org/ml/gdb-patches/2015-07/msg00868.html This adds a test that has a multithreaded program have several threads continuously fork, while another thread continuously steps over a breakpoint. This exposes several intertwined issues, which this patch addresses: - When we're stopping and suspending threads, some thread may fork, and we missed setting its suspend count to 1, like we do when a new clone/thread is detected. When we next unsuspend threads, the fork child's suspend count goes below 0, which is bogus and fails an assertion. - If a step-over is cancelled because a signal arrives, but then gdb is not interested in the signal, we pass the signal straight back to the inferior. However, we miss that we need to re-increment the suspend counts of all other threads that had been paused for the step-over. As a result, other threads indefinitely end up stuck stopped. - If a detach request comes in just while gdbserver is handling a step-over (in the test at hand, this is GDB detaching the fork child), gdbserver internal errors in stabilize_thread's helpers, which assert that all thread's suspend counts are 0 (otherwise we wouldn't be able to move threads out of the jump pads). The suspend counts aren't 0 while a step-over is in progress, because all threads but the one stepping past the breakpoint must remain paused until the step-over finishes and the breakpoint can be reinserted. - Occasionally, we see "BAD - reinserting but not stepping." being output (from within linux_resume_one_lwp_throw). That was because GDB pokes memory while gdbserver is busy with a step-over, and that suspends threads, and then re-resumes them with proceed_one_lwp, which missed another reason to tell linux_resume_one_lwp that the thread should be set back to stepping. - In a couple places, we were resuming threads that are meant to be suspended. E.g., when a vCont;c/s request for thread B comes in just while gdbserver is stepping thread A past a breakpoint. The resume for thread B must be deferred until the step-over finishes. - The test runs with both "set detach-on-fork" on and off. When off, it exercises the case of GDB detaching the fork child explicitly. When on, it exercises the case of gdb resuming the child explicitly. In the "off" case, gdb seems to exponentially become slower as new inferiors are created. This is _very_ noticeable as with only 100 inferiors gdb is crawling already, which makes the test take quite a bit to run. For that reason, I've disabled the "off" variant for now. gdb/ChangeLog: 2015-08-06 Pedro Alves <palves@redhat.com> * target/waitstatus.h (enum target_stop_reason) <TARGET_STOPPED_BY_SINGLE_STEP>: New value. gdb/gdbserver/ChangeLog: 2015-08-06 Pedro Alves <palves@redhat.com> * linux-low.c (handle_extended_wait): Set the fork child's suspend count if stopping and suspending threads.

(linux_wait_1): If passing a signal to the inferior after finishing a step-over, unsuspend and re-resume all lwps.

2013-10-25infrun debug output: print enum gdb_signal symbol names instead of POSIX ↵Pedro Alves1-2/+4
signal names. The other day while debugging something related to random signals, I got confused with "set debug infrun 1" output, for it said: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal 20 On GNU/Linux, 20 is SIGTSTP. For some reason, it took me a few minutes to realize that 20 is actually a GDB signal number, not a target signal number (duh!). In any case, I propose making GDB's output clearer here: One way would be to use gdb_signal_to_name, like already used elsewhere: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal SIGCHLD (20) but I think that might confuse someone too ("20? Why does GDB believe SIGCHLD is 20?"). So I thought of printing the enum string instead: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal GDB_SIGNAL_CHLD (20) Looking at a more complete infrun debug log, we had actually printed the (POSIX) signal name name a bit before: infrun: target_wait (-1, status) = infrun: 9300 [Thread 0x7ffff7fcb740 (LWP 9300)], infrun: status->kind = stopped, signal = SIGCHLD ... infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal 20 So I'm now thinking that it'd be even better to make infrun output consistently use the enum symbol string, like so: infrun: clear_proceed_status_thread (Thread 0x7ffff7fca700 (LWP 25663)) infrun: clear_proceed_status_thread (Thread 0x7ffff7fcb740 (LWP 25659)) - infrun: proceed (addr=0xffffffffffffffff, signal=144, step=1) + infrun: proceed (addr=0xffffffffffffffff, signal=GDB_SIGNAL_DEFAULT, step=1) - infrun: resume (step=1, signal=0), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 + infrun: resume (step=1, signal=GDB_SIGNAL_0), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 infrun: wait_for_inferior () infrun: target_wait (-1, status) = infrun: 25659 [Thread 0x7ffff7fcb740 (LWP 25659)], - infrun: status->kind = stopped, signal = SIGCHLD + infrun: status->kind = stopped, signal = GDB_SIGNAL_CHLD infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x400700 - infrun: random signal 20 + infrun: random signal (GDB_SIGNAL_CHLD) infrun: random signal, keep going - infrun: resume (step=1, signal=20), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 + infrun: resume (step=1, signal=GDB_SIGNAL_CHLD), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 infrun: prepare_to_wait infrun: target_wait (-1, status) = infrun: 25659 [Thread 0x7ffff7fcb740 (LWP 25659)], - infrun: status->kind = stopped, signal = SIGTRAP + infrun: status->kind = stopped, signal = GDB_SIGNAL_TRAP infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x400704 infrun: stepi/nexti infrun: stop_stepping GDB's signal numbers are public and hardcoded (see include/gdb/signals.h), so there's really no need to clutter the output with numeric values in some places while others not. Replacing the magic "144" with GDB_SIGNAL_DEFAULT in "proceed"'s debug output (see above) I think is quite nice. I posit that all this makes it clearer to newcomers that GDB has its own signal numbering (and that there must be some mapping going on).
