Date: Mon, 18 Jul 2016 14:58:00 -0000 Message-Id: <20160718145759.58543-3-jhb@FreeBSD.org> In-Reply-To: <20160718145759.58543-1-jhb@FreeBSD.org> References: <20160718145759.58543-1-jhb@FreeBSD.org> X-IsSubscribed: yes X-SW-Source: 2016-07/txt/msg00192.txt.bz2 New child processes on FreeBSD do not inherit optional ptrace events such as fork and LWP events from the parent process. Instead, explicitly enable events on new children when reporting a fork event. gdb/ChangeLog: * fbsd-nat.c (fbsd_wait): Use "fbsd_enable_proc_events" on new child processes. --- gdb/ChangeLog | 5 +++++ gdb/fbsd-nat.c | 3 +++ 2 files changed, 8 insertions(+) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index dcedc14..33cd6a7 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,10 @@ 2016-07-15 John Baldwin + * fbsd-nat.c (fbsd_wait): Use "fbsd_enable_proc_events" on + new child processes. + +2016-07-15 John Baldwin + * fbsd-nat.c (fbsd_enable_lwp_events): Remove function.
