When using the multi-line feature, we don't want the gdb CLI to remove
comments from the command list, as this will remove things like
"#define".

Move infrun.c declarations out of inferior.h to a new infrun.h file.
Tested by building on:
i686-w64-mingw32, enable-targets=all
x86_64-linux, enable-targets=all
i586-pc-msdosdjgpp
And also grepped the whole tree for each symbol moved to find where
infrun.h might be necessary.

With target async enabled, py-finish-breakpoint.exp triggers an
assertion failure.
The failure occurs because execute_command re-enters the event loop in
some circumstances, and in this case resets the sync_execution flag.
Then later GDB reaches this assertion in normal_stop:
gdb_assert (sync_execution || !target_can_async_p ());
In detail:
#1 - A synchronous execution command is run. sync_execution is set.
#2 - A python breakpoint is hit (TARGET_WAITKIND_STOPPED), and the
corresponding Python breakpoint's stop method is executed. When
and while python commands are executed, interpreter_async is
forced to 0.
#3 - The Python stop method happens to execute a not-execution-related
gdb command. In this case, "where 1".
#4 - Seeing that sync_execution is set, execute_command nests a new
event loop (although that wasn't necessary; this is the problem).
#5 - The linux-nat target's pipe in the event loop happens to be
marked. That's normal, due to this in linux_nat_wait:
/* If we requested any event, and something came out, assume there
may be more. If we requested a specific lwp or process, also
assume there may be more. */
The nested event loop thus immediately wakes up and calls
target_wait. No thread is actually executing in the inferior, so
the target returns TARGET_WAITKIND_NO_RESUMED.
#6 - normal_stop is reached. GDB prints "No unwaited-for children
left.", and resets the sync_execution flag (IOW, there are no
resumed threads left, so the synchronous command is considered
completed.) This is already bogus. We were handling a
breakpoint!
#7 - the nested event loop unwinds/ends. GDB is now back to handling
the python stop method (TARGET_WAITKIND_STOPPED), which decides
the breakpoint should stop. normal_stop is called for this
event. However, normal_stop actually works with the _last_
reported target status:
void
normal_stop (void)
{
struct target_waitstatus last;
ptid_t last_ptid;
struct cleanup *old_chain = make_cleanup (null_cleanup, NULL);
...
get_last_target_status (&last_ptid, &last);
...
if (last.kind == TARGET_WAITKIND_NO_RESUMED)
{
gdb_assert (sync_execution || !target_can_async_p ());
target_terminal_ours_for_output ();
printf_filtered (_("No unwaited-for children left.\n"));
}
And due to the nesting in execute command, the last event is now
TARGET_WAITKIND_NO_RESUMED, not the actual breakpoint event being
handled. This could be seen to be broken in itself, but we can
leave fixing that for another pass. The assertion is reached, and
fails.
execute_command has a comment explaining when it should synchronously
wait for events:
/* If the interpreter is in sync mode (we're running a user
command's list, running command hooks or similars), and we
just ran a synchronous command that started the target, wait
for that command to end. */
However, the code did not follow this comment -- it didn't check to
see if the command actually started the target, just whether the
target was executing a sync command at this point.
This patch fixes the problem by noting whether the target was
executing in sync_execution mode before running the command, and then
augmenting the condition to test this as well.

This patch renames the "set/show remotebaud" commands into
"set/show serial baud", and moves its implementation into serial.c.
It also moves the "baud_rate" global from top.c to serial.c, where
the new code is being added (the alternative was to add an include
of target.h).
And to facilitate the transition to the new setting name, this
patch also preserves the old commands, and marks them as deprecated
to alert the users of the change.

* gdb.base/setshow.exp: Test that relative paths passed to
'set history filename' are converted to absolute paths.
This simplifies the .gdbinit filename selection logic.
We have a GDBINIT_FILENAME define that supposedly configurations would
override, but none do so. Instead, the only configuration that wants
a different file name instead of ".gdbinit", djgpp, does a strcpy over
the gdbinit global array. This means the array needs to be sized, and
the code that does that is doing the usual
'PATH_MAX/FILENAME_MAX/fallback constant/etc.' mess.
Instead of all that, it's much simpler to have configure specificy the
.gdbinit filename. As bonus, we can then make the "gdbinit" global
array const.

Currently, several commands take "0" or "-1" to mean "unlimited".
"show" knows when to print "unlimited":
(gdb) show height
Number of lines gdb thinks are in a page is 45.
(gdb) set height 0
(gdb) show height
Number of lines gdb thinks are in a page is unlimited.
However, the user can't herself specify "unlimited" directly:
(gdb) set height unlimited
No symbol table is loaded. Use the "file" command.
(gdb)
This patch addresses that, by adjusting the set handler for all
integer/uinteger/zuinteger_unlimited commands to accept literal
"unlimited". It also installs a completer. Presently, we complete on
symbols by default, and at
<http://sourceware.org/ml/gdb-patches/2013-03/msg00864.html> I've
shown a WIP prototype that tried to keep that half working in these
commands. In the end, it turned out to be more complicated than
justifiable, IMO. It's super rare to want to pass the value of a
variable/symbol in the program to a GDB set/show knob. That'll still
work, it's just that we won't assist with completion anymore. This
patch just sticks with the simple, and completes on "unlimited", and
nothing else. This simplification means that
"set he<tab><tab>"
is all it takes to get to:
"set height unlimited"
The patch then goes through all integer/uinteger/zuinteger_unlimited
commands in the tree, and updates both the online help and the manual
to mention that "unlimited" is accepted in addition to 0/-1. In the
cases where the command had no online help text at all, this adds it.
I've tried to make the texts read in a way that "unlimited" is
suggested before "0" or "-1" is.

Gareth mentions in PR gdb/15275:
"The MI '-gdb-exit' command mi_cmd_gdb_exit() never calls disconnect_tracing()
and therefore exits correctly."
It should, so to get out of tfind mode, as quit may detach instead of
kill, and we don't want to confuse the memory/register accesses
etc. of the detach process. So we should push down the disconnect
tracing bits at least to quit_force. But we can't as is, as that
would swallow the error thrown by answering "no" to:
Trace is running but will stop on detach; detach anyway? (y or n)
So to address that, we split disconnect_tracing in two. One part that
does the query, and another part that does the rest, and we make
quit_force call the latter.
Looking at quit_force, it does several things, some of which are a bit
independent of the others. It first kills/detaches, and then writes
history, and then runs the final cleanups. It seems better to me to
do each of these things even if the previous thing throws. E.g., as
is, if something throws while detaching, then we skip writing history.
Tested on x86_64 Fedora 17.

The whole readline interface is signed, and works with the 0..INT_MAX
range.
We don't allow setting the size to UINT_MAX directly. The documented
user visible interface is "use 0 for unlimited". The UINT_MAX
representation is an implementation detail we could change, e.g., by
keeping a separate flag for "unlimited", which is actually what the
readline interface does (stifled vs non stifled). Generically
speaking, exposing this detail to clients of the interface may make
our lives complicated when we find the need to extend the range of
some command in the future, and it's better if users
(frontends/scripts) aren't relying on anything but what we tell them
to use for "unlimited". Making values other than 0 error out is the
way to prevent users from using those ranges inappropriately. Quite
related, note:
(gdb) set history size 0xffffffff
integer 4294967295 out of range
But,
(gdb) set history size 0xfffffffe
(gdb) show history size
The size of the command history is unlimited.
(gdb) set history size 0x100000000
integer 4294967296 out of range
If values over INT_MAX are accepted as unlimited, then there's no good
argument for only accepting [INT_MAX..UINT_MAX) as valid "unlimited"
magic numbers, while not accepting [UINT_MAX..inf).
Making the setting's control variable of different type (unsigned int)
of the rest of the related code (int) adds the need to recall that one
variable among all these is unsigned, and that one need to think about
whether these comparisons are signed or unsigned, along with the
promotion/conversion rules. Since this is an easy to forget detail,
this patch renames the variable to at least make it more obvious that
this variable is not one of GNU history's public int variables, which
are all signed. We don't actually need the only code that presently
is affected by this, though, the code that is computing the current
history's length. We can just use GNU history's history_length
instead:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Variable: int history_length
The number of entries currently stored in the history list.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/* Return the history entry which is logically at OFFSET in the history array.
OFFSET is relative to history_base. */
HIST_ENTRY *
history_get (offset)
int offset;
{
int local_index;
local_index = offset - history_base;
return (local_index >= history_length || local_index < 0 || the_history == 0)
? (HIST_ENTRY *)NULL
: the_history[local_index];
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
At the time this code was added (gdb 4.13 ~1994), 'history_length' was
extern, but not documented in readline's GNU history documents, so I
guess it wasn't considered public then and the loop was the
workaround.
One of the warts of GDB choosing 0 to mean unlimited is that "set
history size 0" behaves differently from 'HISTSIZE=0 gdb'. The latter
leaves GDB with no history, while the former means "unlimited"...
$ HISTSIZE=0 ./gdb
...
(gdb) show history size
The size of the command history is 0.
We shouldn't really change what HISTSIZE=0 means, as bash, etc. also
handle 0 as real zero, and zero it's what really makes sense.

This is sort of a continuation of Keith's parse_exp_1 constification
patch. It started out by undoing these bits:
@@ -754,9 +754,12 @@ validate_actionline (char **line, struct
tmp_p = p;
for (loc = t->base.loc; loc; loc = loc->next)
{
- p = tmp_p;
- exp = parse_exp_1 (&p, loc->address,
+ const char *q;
+
+ q = tmp_p;
+ exp = parse_exp_1 (&q, loc->address,
block_for_pc (loc->address), 1);
+ p = (char *) q;
and progressively making more things const upwards, fixing fallout,
rinse repeat, until GDB built again (--enable-targets=all).
That ended up constifying lookup_cmd/add_cmd and (lots of) friends,
and the completers.
I didn't try to constify the command hooks themselves, because I know
upfront there are commands that write to the command string argument,
and I think I managed to stop at a nice non-hacky split point already.
I think the only non-really-super-obvious changes are
tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions.
The rest is just mostly about 'char *' => 'const char *', 'char **'=>
'const char **', and the occasional (e.g., deprecated_cmd_warning)
case of 'char **'=> 'const char *', where/when I noticed that nothing
actually cares about the pointer to pointer output.

The real purpose of this setting is really to override what the debugger
would otherwise guess from checking the stdin settings. So it seems
more natural to see this setting being handled inside gdb_has_a_terminal
rather than input_is_terminal (which checks for other things, such as
whether the input is stdin, for instance).
This patch also adjust the command help and the associated section in
the GDB Manual to be a little clearer about that.

* inflow.c: Include "gdbcmd.h".

(show_interactive_mode): New function, moved here from top.c.
use gdb_has_a_terminal instead of input_from_terminal_p to

setting.

commands. Moved here from top.c, after having adjusted slightly
the help text.

(input_from_terminal_p): Remove handling of "interactive-mode"
setting, moved to infow.c.
(init_main): Remove creation of the "set/show interactive-mode"
commands, moved to inflow.c.
gdb/doc/ChangeLog:
* gdb.texinfo (Other Misc Settings): Rework part of the
documentation of the "set interactive mode" command.
When interactive-mode is not auto, GDB always uses that setting to
determine whether to act as if the input stream is a terminal or not.
However, this setting should only be honored if the input stream is
the standard input stream. Otherwise, we run into trouble while
source-ing a GDB script, as shown below (on x86_64-linux):
% cat script
print 1
print 2
% gdb -q
(gdb) set interactive-mode on
(gdb) source script
(gdb) print 3
$1 = 3
The lack of output and the fact that the "print 3" command returned
