This patch avoids a warning when resuming the execution of a program
that we attached to. For instance:
(gdb) attach 29989
(gdb) continue
Continuing.
warning: Mach error at "/[...]/darwin-nat.c:738" in function
"darwin_resume_thread": (os/kern) failure (0x5)
The warning is relatively harmless, but worrisome for the average
user. The warning comes from the fact that darwin_wait recorded
that the fake stop event corresponding to the suspend action was
caused by the main thread being suspended on a SIGTRAP. As a result
of this, when resuming the program's execution, we try to resume
the thread's execution as well. This is where the issue occurs,
as the thread was not in fact suspended, thus triggering the warning.
gdb/ChangeLog:
* darwin-nat.c (darwin_setup_fake_stop_event): New function.
(darwin_attach): Adjust using darwin_setup_fake_stop_event.
There were many cases were we make a system call which could fail
due to reasons outside of the debugger control. We should handle
these situations a little more gracefully than triggering an
internal error.
gdb/ChangeLog:
* darwin-nat.c (darwin_mourn_inferior): Replace call to
gdb_assert by call to MACH_CHECK_ERROR.
(darwin_attach_pid): Raise an error rather than a failed
assertion when various system calls failed. Report a warning
instead of raising a failed assertion when PREV_NOT is not NULL
after call to mach_port_request_notification.
(darwin_ptrace_me): Raise an error rather than a failed
assertion when read returns nonzero.
gdb_assert.h is already included from darwin-nat.h, so no need to
include it again...
gdb/ChangeLog:
* amd64-darwin-tdep.c: Remove #include "gdb_assert.h".
hashes around loading as-needed library. Zero them on allocation,
and restore to initial all-zero state if library not needed.
Arrange to reuse hashes if we load library again later.
* event-top.c (display_gdb_prompt): Call missing do_cleanups.
* infcmd.c (get_return_value) <!stop_regs>: Do not overwrite CLEANUP.
* symfile.c (symfile_bfd_open): New variable back_to. Do not leave
a stale cleanup. Fix double free of NAME.
* windows-nat.c (windows_delete_thread): Accept an additional
argument, the thread's exit code, and announce thread death when
print_thread_events is non-zero and we are deleting a thread that
is not the main thread.
(get_windows_debug_event): Pass thread exit code to
windows_delete_thread.
