If !PARSE_CONDITION_AND_THREAD, then ARG is just the location, nothing
else. The fact that the describing comment of create_breakpoint
doesn't mention this just looks like an oversight of when extra_string
was added. "parse_condition_and_thread" has been a misnomer ever
since extra_string was added -- better rename it avoid more confusion.
This makes it "parse_arg", as that'll remain stable even if/when more
explicit parameters are added.

If a tracepoint's actions list includes a while-stepping action, and
then the actions are changed to a list without any while-stepping
action, the tracepoint's step_count will be left with a stale value.
For example:
(gdb) trace subr
Tracepoint 1 at 0x4004d9: file ../../../src/gdb/testsuite//actions-changed.c, line 31.
(gdb) actions
Enter actions for tracepoint 1, one per line.

A related issue is that the "commands" command actually supports
setting commands to a range of breakpoints/tracepoints at once. But,
hacking "maint info breakpoints" to print t->step_count, reveals:
(gdb) trace main
Tracepoint 5 at 0x45a2ab: file ../../src/gdb/gdb.c, line 29.
(gdb) trace main
Note: breakpoint 5 also set at pc 0x45a2ab.
Tracepoint 6 at 0x45a2ab: file ../../src/gdb/gdb.c, line 29.
(gdb) commands 5-6
Type commands for breakpoint(s) 5-6, one per line.
End with a line saying just "end".
> while-stepping 5
>end
> end
(gdb) maint info breakpoints 5

^^^^^^^^^^^^
while-stepping 5
end
not installed on target
(gdb)
that tracepoint 6 doesn't end up with the correct step_count.
The issue is that here:
static void
do_map_commands_command (struct breakpoint *b, void *data)
{
struct commands_info *info = data;
if (info->cmd == NULL)
{
struct command_line *l;
if (info->control != NULL)
l = copy_command_lines (info->control->body_list[0]);
else
{
struct cleanup *old_chain;
char *str;
str = xstrprintf (_("Type commands for breakpoint(s) "
"%s, one per line."),
info->arg);
old_chain = make_cleanup (xfree, str);
l = read_command_lines (str,
info->from_tty, 1,
(is_tracepoint (b)
? check_tracepoint_command : 0),
b);
do_cleanups (old_chain);
}
info->cmd = alloc_counted_command_line (l);
}
validate_actionline is never called for tracepoints other than the
first (the copy_command_lines path). Right below, we have:
/* If a breakpoint was on the list more than once, we don't need to
do anything. */
if (b->commands != info->cmd)
{
validate_commands_for_breakpoint (b, info->cmd->commands);
incref_counted_command_line (info->cmd);
decref_counted_command_line (&b->commands);
b->commands = info->cmd;
observer_notify_breakpoint_modified (b);
}
And validate_commands_for_breakpoint looks like the right place to put
a call; if we reset step_count there too, we have a nice central fix
for the first issue as well, because trace_actions_command calls
breakpoint_set_commands that also calls
validate_commands_for_breakpoint.
We end up calling validate_actionline twice for the first tracepoint,
since read_command_lines calls it too, through
check_tracepoint_command, but that should be harmless.

(gdb_trace_setactions, gdb_trace_setcommands): New procedures.
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.
Tested on x86_64 Fedora 17, native and gdbserver.

observer_notify_breakpoints_changed calls. All, except the
init_raw_breakpoint one. But that one is actually wrong. The
breakpoint is being constructed at that point, and hasn't been placed
on the breakpoint chain yet. It would be better placed in
install_breakpoint, and I actually started out that way. But once the
annotate_breakpoints_changed are parallel to the observer calls, we
can fully move annotations to observers too.
One issue is that this changes the order of annotations a bit.
Before, we'd emit the annotation, and after call "mention()" on the
breakpoint (which prints the breakpoint number, etc.). But, we call
the observers _after_ mention is called, so the annotation output will
change a little:
void
install_breakpoint (int internal, struct breakpoint *b, int update_gll)
{
add_to_breakpoint_chain (b);
set_breakpoint_number (internal, b);
if (is_tracepoint (b))
set_tracepoint_count (breakpoint_count);
if (!internal)
mention (b);
observer_notify_breakpoint_created (b);
if (update_gll)
update_global_location_list (1);
}
I believe this order doesn't really matter (the frontend needs to wait
for the prompt anyway), so I just adjust the expected output in the
tests. Emacs in annotations mode doesn't seem to complain. Couple
that with the previous patch that suppressed duplicated annotations,
and, the fact that some annotations calls were actually missing (were
we do have observer calls), more changes to the tests are needed
anyway.

suppress multiple breakpoints-invalid annotations when the ignore
count of a breakpoint changes, up until the target actually stops.
But, the code is bogus:
void
annotate_breakpoints_changed (void)
{
if (annotation_level == 2)
{
target_terminal_ours ();
printf_unfiltered (("\n\032\032breakpoints-invalid\n"));
if (ignore_count_changed)
ignore_count_changed = 0; /* Avoid multiple break annotations. */
}
}
The "ignore_count_changed" flag isn't actually guarding the output of
the annotation at all. It would have been better written something
like:
void
annotate_breakpoints_changed (void)
{
if (annotation_level == 2 && !ignore_count_changed)
{
target_terminal_ours ();
printf_unfiltered (("\n\032\032breakpoints-invalid\n"));
ignore_count_changed = 0; /* Avoid multiple break annotations. */
}
}
but, it wasn't. AFAICS, that goes all the way back to the original
patch'es submission and check in, at
<http://sourceware.org/ml/gdb-patches/1999-q4/msg00106.html>. I
looked a tar of HP's wdb from 1999, and even though that contains
local changes in the annotate code, this suppression seems borked
there too to me.
The original patch added a test to supposedly exercise this
suppression, but, it actually doesn't. It merely tests that
"breakpoints-invalid" is output after "stopped", but doesn't check
whether the duplicates supression actually works (IOW, check that only
_one_ annotation is seen). I was going to simply delete the tests
too, but a following patch will eliminate the duplicates in a
different way (which I needed for a different reason), so instead, I'm
making the tests actually fail if a duplicate annotation is seen.
Worry not, the test doesn't actually fail! The reason is that
breakpoint.c does:
else if (b->ignore_count > 0)
{
b->ignore_count--;
annotate_ignore_count_change ();
bs->stop = 0;
/* Increase the hit count even though we don't stop. */
++(b->hit_count);
observer_notify_breakpoint_modified (b);
}
where the annotate_ignore_count_change call is meant to inform the
"breakpoint_modified" annotation observer to ignore the notification.
All sounds good. But, the trouble is that nowadays annotate.c only
installs the observers if GDB is started with annotations enabled with
a command line option (gdb --annotate=2):
void
_initialize_annotate (void)
{
if (annotation_level == 2)
{
observer_attach_breakpoint_deleted (breakpoint_changed);
observer_attach_breakpoint_modified (breakpoint_changed);
}
}
and annota1.exp, to enable annotations, starts GDB normally, and
afterwards does "set annotate 2", so the observers aren't installed
when annota1.exp is run, and therefore changing the ignore count isn't
triggering any annotation at all...

Before this change, detach_breakpoints would take a pid, and then
set inferior_ptid to a ptid that it constructs using pid_to_ptid (pid).
Unfortunately, this ptid is not necessarily valid. Consider for
instance the case of ia64-hpux, where ttrace refuses a register-read
operation if the LWP is not provided.
This problems shows up when GDB is trying to handle fork events.
Assuming GDB is configured to follow the parent, GDB will try to
detach from the child. But before doing so, it needs to remove
all breakpoints inside that child. On ia64, this involves reading
inferior (the child's) memory. And on ia64-hpux, reading memory
requires us to read the bsp and bspstore registers, in order to
determine where that memory is relative to the value of those
registers, and thus to determine which ttrace operation to use in
order to fetch that memory (see ia64_hpux_xfer_memory).
This patch therefore changes detach_breakpoints to take a ptid instead
of a pid, and then updates all callers.
One of the consequences of this patch is that it trips an assert
on GNU/Linux targets. But this assert appears to have not actual
purpose, and is thus removed.

With an Ada program, trying to break on a specific Ada task, but
with the wrong capitalization of the `task' keyword, we currently
get only pieces of the "garbage" that caused the error:
(gdb) b *rendez_vous'address TASK 2
Garbage 2 at end of command
Pushing this a little further:
(gdb) b *rendez_vous'address TASK Task TaSK 2
Garbage 2 at end of command
Another interesting failure mode:
(gdb) b *rendez_vous'address TASK if
Argument required (expression to compute).
The parser skipped `TASK', then found the `if' keyword, and thus
started looking for a condition.
This patch fixes the problem by aborting the parsing as soon as
an invalid keyword is found. This makes it consistent with the
case where the REST parameter is passed as NULL (where an error
is raised immediately after seeing the first invalid keyword).
It also introduces a new testcase that reproduces all above scenarios.

When debugging on Windows with GDBserver, the debugger starts
failing after hitting a breakpoint. For instance:
(gdb) b foo
Breakpoint 1 at 0x40177e: file foo.adb, line 5.
(gdb) cont
Continuing.
Breakpoint 1, foo () at foo.adb:5
5 Put_Line ("Hello World."); -- STOP
(gdb) n
Program received signal SIGSEGV, Segmentation fault.
0x00401782 in foo () at foo.adb:5
5 Put_Line ("Hello World."); -- STOP
There are two issues:
1. While trying to re-insert a breakpoint that is still inserted
in memory, insert_bp_location wipes out the breakpoint location's
shadow_contents. As a consequence, we cannot restore the proper
instruction when removing the breakpoint anymore. That's why
the inferior's behavior changes when trying to resume after
the breakpoint was hit.
2. mem-break.c:default_memory_insert_breakpoint passes a breakpoint
location's shadow_contents as the buffer for a memory read.
This reveals a limitation of the various memory-read target
functions. This patch documents this limitation and adjust
the two calls that seem to hit that limitation.
gdb/ChangeLog:
* breakpoint.c (breakpoint_xfer_memory): Add assertion.
Update function description.
(insert_bp_location): Do not wipe bl->target_info out.
* mem-break.c: #include "gdb_string.h".
(default_memory_insert_breakpoint): Do not call target_read_memory

a local buffer instead.
* m32r-tdep.c (m32r_memory_insert_breakpoint): Ditto.
The 3 valid values for this setting are "auto", "host" and "target".
The help was advertising one of them to be "gdb" instead of "host".

Initially, I noticed that the save command was often missing
new lines in the file that it generated. For instance, consider:
% gdb save-bp
(gdb) b break_me
(gdb) b save-bp.c:27
(gdb) save breakpoints bps
The contents of the bps file would be:
% cat bps
break break_mebreak save-bp.c:27
Looking further into the problem, I realized that the missing newlines
are just a consequence of a missing call to print_recreate_thread.
After having generated the breakpoint location in the break command,
we cannot put a new line until we have looked at whether we need to
add a 'thread NUM' argument.

This rewrites the code generating the Ada exception catchpoint hit
notification for both the GDB/MI case as well as the non-MI case,
by using the relevant ui_out_* functions to generate the output.
the MI notifications for Ada exception catchpoints now include
the stop reason, and the breakpoint "disp", much like other breakpoint
events do. It also introduces a new field "exception-name" for
exception catchpoints (excluding "failed assertion catchpoints,
where we just want to know that it was a failed assertion).
