First, left me offer my apologies for the length of this series.  It
was somewhat simpler to break it into many tiny pieces, because
sometimes when const-ifying it is easy to get in over one's head.  On
the plus side, nearly all of the patches are trivial and so review
should not be too difficult -- just boring.

This starts by adding const-correct overloads of add_cmd and a few
related functions.  Then, it converts many functions to use the
const-correct form.  The idea is to gradually convert all commands
(and set/show, etc) to const-correctness, then remove the non-const
overloads.

Regression tested on the buildbot.

Tom

This adds two add_cmd overloads: one whose callback takes a const char *,
and one that doesn't accept a function at all.  The no-function overload
was introduced to avoid ambiguity when NULL was passed as the function.

Long term the goal is for all commands to take const arguments, and
for the non-const variants to be removed entirely.

ChangeLog
2017-09-20  Tom Tromey  <tom@tromey.com>

	* cli/cli-decode.c (add_cmd, set_cmd_cfunc): New function
	overloads.
	(do_add_cmd): Rename from add_cmd.  Don't call set_cmd_cfunc.
	(do_const_cfunc): New function.
	(cmd_cfunc_eq): New overload.
	(cli_user_command_p): Check do_const_cfunc.
	* cli/cli-decode.h (struct cmd_list_element) <function>: New field
	const_cfunc.
	* command.h (add_cmd): Add const overload and no-function
	overload.
	(set_cmd_cfunc): Add const overload.
	(cmd_const_cfunc_ftype): Declare.
	(cmd_cfunc_eq): Add const overload.
	* breakpoint.c, cli-cmds.c, cli-dump.c, guile/scm-cmd.c,
	python/py-cmd.c, target.c, tracepoint.c: Use no-function add_cmd
	overload.

We shouldn't really have the NULL case, anymore.  It is still possible  but I don't expect it to be used.  Should we assert CFUNC != NULL?

Should we also set CMD->FUNCTION.CFUNC to NULL?

Should we instead set all the respective fields to NULL?

Should we also set RESULT->FUNCTION.CONST_CFUNC to NULL?

If that's possible, then it'd be nice to add ATTRIBUTE_NONNULL
on the declaration too.

I think not, because it's a union.

Thanks,

Markus> Ok.?

This is copy-and-paste from the other function like this.
I think this is some way to suppress ARI warnings.
I don't know if ARI is still used...?

I did this.

I thought so too, though grepping for "Ok" in the ARI finds
no hits.  We have some markers in the tree for ARI, but they
start with "ARI: ".  I'd zap the "Ok." comments see what happens.
You can run the ARI locally and compare with/without "Ok."
comments, with something like:

  gdb/contrib/ari/gdb_ari.sh -Wall gdb/cli/cli-decode.c

> I don't know if ARI is still used...?

It was still sending notifications to the list as recently as
this month.

Thanks,

Seems fine, so I've updated the patch accordingly.

Can you please add some comments describing the difference between the

The rest of the declarations are at the beginning.  I'd prefer to keep it that way.

Interesting.  Out of curiosity, is there a particular reason for
that preference?  I ask because we haven't adjusted our guidelines
in this area yet, but I've been asking people to move
declarations nearer where they're initialized in patch reviews.
My reasoning for that has been that IMHO, declarations nearer to
where they're initialized help with a few things:

 - helps with reasoning about the code, since the type of
   the variable has more changes of being visible.  The
   top of the scope may be a good number of lines above.

 - helps prevent accidental used-uninitialized bugs.

 - avoid gratuitous pessimization when the variable is of
   non-trivial type, by avoiding separate default
   construction + assignment steps.  (though that's not the
   case here, since in this case all variables are scalars).

The point that I feel particularly strongly about is the
last one, about non-trivial types, though as said that
doesn't apply in this case.

For the first two points, in C89, we'd some times open a
extra scope, like in this case you could write:

    {
      char *end;
      long result = strtol (pos, &end, 10);

      *arg = end;
      return result;
    }

In C99/C++, we can write declarations in the middle of
blocks without forcing the extra scope.

It's really up to you the style to use for this code as
btrace maintainer, but I hope that at least this clarifies
things for those that end up being asked different
things from different people.  :-)

Thanks,
Pedro Alves

My reason is simply to not mix different styles.

That shouldn't be the case.  If GDB is moving from a separate
declaration block to mixed-in declarations we should do it
everywhere.

So please ignore my comments on declaration placement.

Markus.

Alright, that's certainly a valid reason.

My view is that declarations in the middle of blocks are
desirable, and enforcing top-of-block-only consistency too
strongly prevents incremental modernization a bit, since it
puts the bar higher (because either everything is converted,
or else nothing is).  So personally I'm fine with mixed style,
and I try to push for declare-at-initialization when it
makes sense.

Ack.  To me, if we need a simpler rationale, it could go
like this: middle-of-block declaration+initialization makes
sense with non-trivial types.  And if we accept middle-of-block
declarations with non-trivial types, then there's no good
rationale for not allowing them with scalar types too.

On the contrary, it's not my intention to make your comment
be ignored, rather that we all discuss this and end up on
the same page.  So thanks for the discussion, and really sorry
if I sounded too nit picky.

-----

BTW, looking at the get_context_size function in question, it
seems like the 'number' variable is not used, meaning we could
apply something like this:

 static int
 get_context_size (char **arg)
 {
-   char *pos;
-   int number;
-
-  pos = skip_spaces (*arg);
+  char *pos = skip_spaces (*arg);

   if (!isdigit (*pos))
     error (_("Expected positive number, got: %s."), pos);

   return strtol (pos, arg, 10);
 }

Thanks,
Pedro Alves

I find top declarations more readable but I see the need for
C++ objects.  And I value consistency.  So let's go with mixed
style everywhere.

Agreed.

Tom still needs to ignore my previous comment on declaration
placement;-)  In this and in other patches of this series.

Tom's patch changed the parameter to const char so we still need the
char *end detour.  You're right, though, that NUMBER is not used and
that the declaration can be removed.

Thanks,
Markus.

This changes a few linespec functions to work on "const char *" and
then fixes up all the callers.  This allows further constification
elsewhere.

I'd be nice to mention in the commit log the reason for this.
I assume that it's because we don't have the corresponding
constified add_cmd variant?

Thanks,

Hmm... normally I think it should be used.
Like in this patch (#38):

-info_scope_command (char *args, int from_tty)
+info_scope_command (char *args_in, int from_tty)
...
-  char *save_args = args;
+  const char *save_args = args_in;
...
+  const char *args = args_in;

Pedro> I'd be nice to mention in the commit log the reason for this.
Pedro> I assume that it's because we don't have the corresponding
Pedro> constified add_cmd variant?

In this case I believe the reason is that info_scope_command could not
be constified yet, because add_info isn't constified; but on the other
hand it calls string_to_event_location, which is now constified, and it
didn't seem worthwhile to overload that.

I think all the cases *should* be things like this, but of course there
may be errors.

Tom

Nice, this fixes a potential leak.  OK.

This also makes delete_command static; but now I wonder if it is used
in Insight and should not be touched.

[Adding Patrick]

Insight git is on sourceware nowadays:
  git://sourceware.org/git/insight.git

$ git grep delete_command
...
gdbtk/generic/gdbtk-cmds.c:  delete_command (NULL, 0);

I guess it'd be mildly nicer to add some "void delete_all_breakpoints();"
API instead of abusing the command callback.

Thanks,
Pedro Alves

I've just added such an API to the insight code:
https://sourceware.org/git/?p=insight.git;a=commit;h=7dc503fbf209ec7f39771c2bf5e45e01974f18c5
It works fine without calling delete_command(). Thus it's OK for me to 
have static delete_command().

@palves: many thanks for having raised the flag before commit.

Patrick

... this fixes an actual bug:

 (gdb) tfind range 1, 2
 Breakpoint 4, tfind_range_command (args=0x30a0cbc "1, 2", from_tty=1) at src/gdb/tracepoint.c:2496
 ...
 (top gdb) c
 (gdb) <enter again for repeat>
 Breakpoint 4, tfind_range_command (args=0x30a0cbc "1", from_tty=1) at src/gdb/tracepoint.c:2496

Which is great, and shows that constification pays off.

I think it'd have been nice to split fixes like these to a
separate patch, or at least mention them in the commit log, though.

[/me goes read patches 2-40 again to double check.]

Thanks,

I wasn't actually even aware of that.

I added this to the commit message:

  In addition to the constification, this fixes a command-repeat bug.

Note that this commit also changes deprecated_file_changed_hook -- not
used in the tree, but Insight will require a (presumably minor)
change.

I've read the whole series and sent a few comments, but it
all looks generally fine to me.  Those patches that I haven't
commented on looked OK as-is to me.

Thanks for doing all this.

I think you're pretty much good to go.  Let me know if you're
waiting for something that I missed.
