@appendix @value{GDBN} Currently available observers
@section Implementation rationale
@cindex observers implementation rationale
An @dfn{observer} is an entity which is interested in being notified
when GDB reaches certain states, or certain events occur in GDB.
The entity being observed is called the @dfn{subject}. To receive
notifications, the observer attaches a callback to the subject.
One subject can have several observers.
@file{observer.c} implements an internal generic low-level event

2003-04-03 15:14:48 +00:00
notification mechanism. This generic event notification mechanism is

2003-03-18 17:44:23 +00:00
then re-used to implement the exported high-level notification
management routines for all possible notifications.
The current implementation of the generic observer provides support
for contextual data. This contextual data is given to the subject
when attaching the callback. In return, the subject will provide
this contextual data back to the observer as a parameter of the
callback.
Note that the current support for the contextual data is only partial,
as it lacks a mechanism that would deallocate this data when the
callback is detached. This is not a problem so far, as this contextual
data is only used internally to hold a function pointer. Later on, if
a certain observer needs to provide support for user-level contextual

enhanced to allow the observer to provide a routine to deallocate the
data when attaching the callback.
The observer implementation is also currently not reentrant.
In particular, it is therefore not possible to call the attach
or detach routines during a notification.

PR gdb/13860 - Make MI sync vs async output (closer to) the same. Ignoring expected and desired differences like whether the prompt is output after *stoppped records, GDB MI output is still different in sync and async modes. In sync mode, when a CLI execution command is entered, the "reason" field is missing in the *stopped async record. And in async mode, for some events, like program exits, the corresponding CLI output is missing in the CLI channel. Vis, diff between sync vs async modes: run ^running *running,thread-id="1" (gdb) ... - ~"[Inferior 1 (process 15882) exited normally]\n" =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" si ... (gdb) ~"0x000000000045e033\t29\t memset (&args, 0, sizeof args);\n" - *stopped,frame=...,thread-id="1",stopped-threads="all",core="0" + *stopped,reason="end-stepping-range",frame=...,thread-id="1",stopped-threads="all",core="0" (gdb) In addition, in both cases, when a MI execution command is entered, and a breakpoint triggers, the event is sent to the console too. But some events like program exits have the CLI output missing in the CLI channel: -exec-run ^running *running,thread-id="1" (gdb) ... =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" We'll want to make background commands always possible by default. IOW, make target-async be the default. But, in order to do that, we'll need to emulate MI sync on top of an async target. That means we'll have yet another combination to care for in the testsuite. Rather than making the testsuite cope with all these differences, I thought it better to just fix GDB to always have the complete output, no matter whether it's in sync or async mode. This is all related to interpreter-exec, and the corresponding uiout switching. (Typing a CLI command directly in MI is shorthand for running it through -interpreter-exec console.) In sync mode, when a CLI command is active, normal_stop is called when the current interpreter and uiout are CLI's. So print_XXX_reason prints the stop reason to CLI uiout (only), and we don't show it in MI. In async mode the stop event is processed when we're back in the MI interpreter, so the stop reason is printed directly to the MI uiout. Fix this by making run control event printing roughly independent of whatever is the current interpreter or uiout. That is, move these prints to interpreter observers, that know whether to print or be quiet, and if printing, which uiout to print to. In the case of the console/tui interpreters, only print if the top interpreter. For MI, always print. Breakpoint hits / normal stops are already handled similarly -- MI has a normal_stop observer that prints the event to both MI and the CLI, though that could be cleaned up further in the direction of this patch. This also makes all of: (gdb) foo and (gdb) interpreter-exec MI "-exec-foo" and (gdb) -exec-foo and (gdb) -interpreter-exec console "foo" print as expected.

Make display_gdb_prompt CLI-only. Enabling target-async by default will require implementing sync execution on top of an async target, much like foreground command are implemented on the CLI in async mode. In order to do that, we will need better control of when to print the MI prompt. Currently the interp->display_prompt_p hook is all we have, and MI just always returns false, meaning, make display_gdb_prompt a no-op. We'll need to be able to know to print the MI prompt in some of the conditions that display_gdb_prompt is called from the core, but not all. This is all a litte twisted currently. As we can see, display_gdb_prompt is really CLI specific, so make the console interpreters (console/tui) themselves call it. To be able to do that, and add a few different observers that the interpreters can use to distinguish when or why the the prompt is being printed: #1 - one called whenever a command is cancelled due to an error. #2 - another for when a foreground command just finished. In both cases, CLI wants to print the prompt, while MI doesn't. MI will want to print the prompt in the second case when in a special MI mode. The display_gdb_prompt call in interp_set made me pause. The comment there reads: /* Finally, put up the new prompt to show that we are indeed here. Also, display_gdb_prompt for the console does some readline magic which is needed for the console interpreter, at least... */ But, that looks very much like a no-op to me currently: - the MI interpreter always return false in the prompt hook, meaning actually display no prompt. - the interpreter used at that point is still quiet. And the console/tui interpreters return false in the prompt hook if they're quiet, meaning actually display no prompt. The only remaining possible use would then be the readline magic. But whatever that might have been, it's not reacheable today either, because display_gdb_prompt returns early, before touching readline if the interpreter returns false in the display_prompt_p hook.

An inferior function at @var{address} is about to be called in thread

thread in which the function was called, which may be different from the
current thread.
