"add".  The code in GDB can be simplified.

target_read_memory&co: no longer return target_xfer_status

Years ago, these functions used to return errno/EIO.  Later, through a
series of changes that intended to remove native/remote differences,
they ended up returning a target_xfer_status in disguise.

Unlike target_xfer_partial&co, the point of target_read_memory&co is
to either fully succeed or fail.  On error, they always return
TARGET_XFER_E_IO.  So there's no real point in casting the return of
target_read_memory to a target_xfer_status to pass it to memory_error.
Instead, it results in clearer code to simply decouple
target_read_memory&co's return from target_xfer_status.

ctf.c: Fix int/enum implicit cast

This patch was taken directly from Pedro's branch.

Right now, SET_INT32_FIELD is used to set enum fields.  This works in C,
but not C++.  Therefore, define the new SET_ENUM_FIELD, which casts the

(ctf_read_tp): Use it.

9 years agoFix inconsistent breakpoint kinds between breakpoints and tracepoints in GDBServer.
Antoine Tremblay [Thu, 22 Oct 2015 16:21:51 +0000 (12:21 -0400)]
Fix inconsistent breakpoint kinds between breakpoints and tracepoints in GDBServer.

This patch fixes a regression introduced by :
https://sourceware.org/ml/gdb-patches/2015-10/msg00369.html

Tests : gdb.trace/trace-break.exp and gdb.trace/trace-mt.exp would fail on x86
with gdbserver-{native,extended}.

Before this patch, the breakpoint kind set by GDB with a Z packet and the one
set in the case of a tracepoint would be inconsistent on targets that did not
implement breakpoint_kind_from_pc. On x86 for example a breakpoint set by GDB
would have a kind of 1 but a breakpoint set by a tracepoint would have a kind of
0.

This created a missmatch when trying to insert a tracepoint and a breakpoint at
the same location. One of the two breakpoints would be removed with debug
message : "Inconsistent breakpoint kind".

This patch fixes the issue by changing the default 0 breakpoint kind to be
the size of the breakpoint according to sw_breakpoint_from_kind.

The default breakpoint kind must be the breakpoint length to keep consistency
between breakpoints set via GDB and the ones set internally by GDBServer.

No regression on Ubuntu 14.04 x86-64 with gdbserver-{native-extended}

Pedro Alves [Thu, 22 Oct 2015 15:40:45 +0000 (16:40 +0100)]
gdb/Windows: use windows_wait/windows_resume directly in initial startup

Explation below based on what Joel wrote at:

  https://sourceware.org/ml/gdb-patches/2015-10/msg00274.html

The merge async/sync code paths patch broke attaching on Windows.

This is what we observe, after attaching to any process.  At first, it
seems like everything worked fine, since the process stops, and we get
the prompt back:

    (gdb) att 3156
    Attaching to program `C:\[...]\foo.exe', process 3156
    [New Thread 3156.0xcd8]
    [New Thread 3156.0xfe4]
    0x7770000d in ntdll!DbgBreakPoint () from C:\Windows\SysWOW64\ntdll.dll
    (gdb)

However, enter any commands at all, and GDB appears to be hanging.
For instance:

    (gdb) set lang ada
    [nothing happens]

Despite appearances, GDB is not reading from the prompt.  It is
blocked waiting for an event from the inferior.  And since our
inferior is stopped, there aren't going to be any events to read.

In chronological order, what happens is that windows_attach calls
do_initial_windows_stuff, which performs the inferior creation,
and repeatedly waits until we get the first SIGTRAP:

  while (1)
    {
      stop_after_trap = 1;
      wait_for_inferior ();
      tp = inferior_thread ();
      if (tp->suspend.stop_signal != GDB_SIGNAL_TRAP)
        resume (tp->suspend.stop_signal);
      else
        break;
    }

The call to wait_for_inferior triggers a call to do_target_wait to get
the event, followed by handle_inferior_event to process it.  However,
because the first couple of events are "spurious" events, GDB resumes
the execution, and prepares the inferior to wait again:

    case TARGET_WAITKIND_SPURIOUS:
      [...]
      resume (GDB_SIGNAL_0);
      prepare_to_wait (ecs);

And prepare_to_wait just does...

  ecs->wait_some_more = 1;
  if (!target_is_async_p ())
    mark_infrun_async_event_handler ();

... which as a result sets the infrun_async_event_handler "ready"
flag to 1.

We get a couple of spurious events before we get the initial SIGTRAP,
at which point we exit the "while (1)" loop above, after which we
reach the end of the attach_command, followed by the normal
end-of-command processing (normal_stop, bp handling, printing the GDB
prompt), back finally to the root of the event loop.

Notice that, at this point, nothing has unset the "ready" flag for the
infrun_async_event_handler.  So, when another cycle of
gdb_do_one_event from the event loop, we eventually call
check_async_event_handlers, which finds that the infrun async event
handler is "ready", and therefore calls it's associated "proc"
callback, which does...

      inferior_event_handler (INF_REG_EVENT, NULL);

... triggering a blocking call to target_wait, thus hanging forever.

The fix is to use windows_wait and windows_resume directly, similarly
to gdbserver.  This will also allow getting rid of 'stop_after_trap'.
