RE: New ARI warning Sat Mar 12 01:53:29 UTC 2011

[Pierre Muller]

  This is the consequence of the two new ARI rules I added:
http://sourceware.org/ml/gdb-patches/2011-03/msg00654.html

  As I just introduced these new rules,
I felt that it would be cheating to
use OBVIOUS rule as we normally do to fix 
a ARI regression...
  This is why I will submit shortly two patches
to remove all those new warnings.

[RFA] Fix ARI warning about function call in first column (was : New ARI warning Sat Mar 12 01:53:29 UTC 2011)

[Pierre Muller]

This second patch fixes:
> gdb/hppa-tdep.h:244: code: function call in first column: Function name in
first column should be restricted to function implementation
gdb/hppa-tdep.h:244:hppa_init_objfile_priv_data (struct objfile *objfile);
and other occurrences of same new warning.

OK to apply?

The rule to detect "()" without a "void" is fine, but why on Earth do
we need the other rule, about prototypes like this:

  int
  foo (bar);

This is a perfectly valid formatting.  In your patch, you modify long
prototypes like this as follows:

   extern struct hppa_objfile_private *
  -hppa_init_objfile_priv_data (struct objfile *objfile);
  +  hppa_init_objfile_priv_data (struct objfile *objfile);

But that is not a good idea, because if you type TAB in Emacs on the
line with the function name, Emacs will reindent the name to column
zero.  So I expect this rule to annoy us quite a bit, e.g. if someone
reindents a large region.

Can you tell why we need this?

  See
http://sourceware.org/ml/gdb-patches/2011-03/msg00651.html

  This way you will find only the implementation of function foo_function
using grep:

grep "^foo_function" *

  I really thought that prototypes,
either in header or in C sources should not be found by that
pattern and that it shouls thus either be on a single line,
or be indented to avoid being on first column.

 Notice that the new rule only found a few of these
extern TYPE
long_func_name (with_long_parameters);

  Would it be better to reformat those as
extern TYPE long_func_name 
  (with_long_parameters);
instead of
extern TYPE
  long_func_name (with_long_parameters);

  I have no preference on that matter,
I would really like to avoid getting both the
prototype and the implementation if I do:

grep "^func_name " 

That's the reason of this rule.

  Tell us what you think about the alternate
I propose above and what we should do in your opinion.

That was about _definitions_, not about declarations of prototypes.

Anyway, I don't see how is it relevant: that message talks about the
need to put the names of the functions in the beginning of a line (a
long standing GNU coding style practice), exactly the practice which
will according to your change trigger ARI warnings when used with a
prototype.

Are we adding ARI warnings to help ARI find function implementations
and skip prototypes?  If this is the need, why not look for the
semi-colon at the end of the prototype, which will be absent in
function definitions?

No, that's even uglier.

Then let's find a smarter way of finding just the implementation.
Forcing some unusual style on our code to help Grep is not a good
idea, IMO.

But it's what we do all over.  We do have the rule that
grep "^foofunc" should only match function definitions, not
declarations.  Here in gdbint.texinfo:

"A function declaration should not have its name in column zero.  A
function definition should have its name in column zero."

  Thank you for finding this out...
This is clearer than what I try to explain to Eli before.

  Eli, do you agree with this statement 
in gdbint.textinfo or should it be modified?

  Would you like to enhance it to specify what to do if
the whole function declaration
TYPE NAME (PARAMS);
doesn't fit into a 80 columns line?

 I am willing to adapt the ARI rule to such recommendations.

At the very least, please reformat the prototypes like this:

extern whatever_type foo (type1_t,
       		     	  type2_t, const char **, foobar_t);

not like Pierre originally suggested.

That is, let the left paren and at least one argument be on the same
line as the function name.

  Eli, the only C coding standard I was ever confronted with 
is GDB coding standards.
  And this is probably one of the first rules
that I understood.
  I find this rule quite useful, as it allows
easy tracking of function implementation.

  I agree with the principle, but
it is not always possible:

What should we do with this:
$ grep -n -C 3 "^[a-z][a-z0-9_]*[[:space:]]*(.*)" *.h
linux-nat.h-147-/* Create a generic GNU/Linux target using traditional
linux-nat.h-148-   ptrace register access.  */
linux-nat.h-149-struct target_ops *
linux-nat.h:150:linux_trad_target (CORE_ADDR (*register_u_offset)(struct
gdbarch *, int, int));
linux-nat.h-151-
linux-nat.h-152-/* Register the customized GNU/Linux target.  This should be
used
linux-nat.h-153-   instead of calling add_target directly.  */

 OK, I must admit that I cheated, because that did not even appear in the
ARI list,
while it should.
  It should be in the list because it is one of the
functions declarations that are in first column,
it does not appear because I oversimplified the rule
using 
/^[a-z][a-z0-9_]*[[:space:]]*\((|[^*][^()]*)\)[[:space:]]*[^ \t]+/ 
awk pattern to avoid getting all function variables.
  If someone can suggest a more complete pattern that would also
grab the above without matching 
int (*test_var_function (int, int));
I would be grateful.

Pierre

I'm fine with your suggestion, and in fact it's my preference
as well.  However, there _are_ cases where you just can't do that,
because the return type + function name + parameter end up being
too long for a single line.  It's even easier to happen when you need
to spell out the parameter name, not just the type (to refer
to in the describing comment).

That sentence says what one should _not_ do.  The issue in this thread
is what to do instead.

I suggested how to format that case.  If that suggestion is accepted,
I will change gdbint.texinfo accordingly.

Either

struct target_ops *linux_trad_target (CORE_ADDR (*register_u_offset)(struct gdbarch *,
                                                                     int, int));

or even

struct target_ops *linux_trad_target (CORE_ADDR (*register_u_offset)(struct gdbarch *, int, int));

IOW, such marginal examples are not interesting (one should use a
typedef for that function argument, anyway, to make the prototype
legible).

What's wrong with leaving a single long line in such cases?  They are
supposed to be very rare (if typedefs are used for complex function
arguments).

If we have a rule to follow, we should follow it everywhere.
And they are not very rare; we have quite a few cases.  The most
prominent styles are:

/* Find a particular location expression from a location list.  */
const gdb_byte *dwarf2_find_location_expression
  (struct dwarf2_loclist_baton *baton,
   size_t *locexpr_length,
   CORE_ADDR pc);

/* Find an inferior bound to PSPACE.  */
extern struct inferior *
  find_inferior_for_program_space (struct program_space *pspace);

  Take for instance a look at hppa-tdep.h:
my patch changes
<<<hppa-tdep.h>>>>
extern struct hppa_objfile_private *
hppa_init_objfile_priv_data (struct objfile *objfile);
<<<hppa-tdep.h>>>>
into:

<<<hppa-tdep.h>>>>
extern struct hppa_objfile_private *
  hppa_init_objfile_priv_data (struct objfile *objfile);
<<<hppa-tdep.h>>>>

Your suggestion would lead to:
<<<hppa-tdep.h>>>>
extern struct hppa_objfile_private * hppa_init_objfile_priv_data (struct
objfile *objfile);
<<<hppa-tdep.h>>>>

on a single line (might have been corrupted by my mailer...)
91 column wide...

but if you look at the rest of the hppa-tdep.h file, you will find:

<<<hppa-tdep.h>>>>
extern struct value *
  hppa_frame_prev_register_helper (struct frame_info *this_frame,
                                   struct trad_frame_saved_reg *saved_regs,
                                   int regnum);

extern CORE_ADDR hppa_read_pc (struct regcache *regcache);
extern void hppa_write_pc (struct regcache *regcache, CORE_ADDR pc);
extern CORE_ADDR hppa_unwind_pc (struct gdbarch *gdbarch,
                                 struct frame_info *next_frame);

extern struct minimal_symbol *
  hppa_lookup_stub_minimal_symbol (const char *name,
                                   enum unwind_stub_types stub_type);

extern struct hppa_objfile_private * hppa_init_objfile_priv_data (struct
objfile
 *objfile);

extern int hppa_in_solib_call_trampoline (struct gdbarch *gdbarch,
                                          CORE_ADDR pc, char *name);
extern CORE_ADDR hppa_skip_trampoline_code (struct frame_info *, CORE_ADDR
pc);
<<<hppa-tdep.h>>>>

  So you can see that the ugly formatting, I proposed is already
used twice.
  I found 37 occurrences listed below,
should we considered those as badly formatted?

  As Eli had some concerns about that part,
I tried to change my patch so that it does add new
function declarations split in between return type and 
function name.
  
  Eli, this still leaves us with two 
cases for which we either have
TYPE
  NAME (PARAMS);
or
TYPE NAME (PARAMS);
with a single line that exceeds 80 columns.

  I didn't really understand your comment about
automatic indenting by emacs because I never used emacs :(
As the 37 already existing cases suggest,
this couldn't have worked correctly even before my patch, no?

  If you really prefer and others also agree,
I can submit a variant with single lines...

Pierre

If you want, you can commit the obviously ok ones in the meantime.
Nearly all of your patch seems uncontroversial.

I see no problem with long lines, if there are no better alternatives.
I generally dislike tools that raise warnings for perfectly valid and
readable code, and I don't think we must every follow minor stylistic
rule when that rule gives sub-optimal results.

But it sounds like I'm the only one (again).  So I give up: do
whatever you and others think is right, and I will crawl back under my
rock.


>   I didn't really understand your comment about

In Emacs, hitting the TAB key anywhere on a line of code reindents
this line according to the current setting of the coding style.  The
default coding style is, not surprisingly, the GNU coding style
described in standards.texi.

So, when you hit TAB in a C source file on the second of the two lines
that say

TYPE
  NAME (PARAMS);

Emacs reindents it like this:

TYPE
NAME (PARAMS);

You can also re-indent a whole region of source in Emacs, by marking
the region and pressing TAB.  This is a very convenient way of
reformatting a large portion of code according to GNU standards (which
mostly happen to be GDB standards as well).  When you re-indent a
large region like that, it is easy to undo the kind of formatting you
want to enforce, shown above, because you will not generally go back
and examine each line of the reformatted region -- you trust Emacs to
DTRT.

The  net  result  will  be,   I  fear,  that  such  reformatting  will
inadvertently  undo the  indentation  of prototypes,  and trigger  ARI
warnings for no good reason.

I hope I made myself clear this time.

  Don't do it, I finally committed something that should suit
you as well...

  Thanks for the explanation.

  Here is what I finally checked in,
it does avoid indented lone function names.

  Personally, I would have done it like this:
TYPE FUNC_NAME (
  PARAMS);
or
TYPE FUNC_NAME (
  PARAM1,
  PARAMS);

but this is another problem.

  This should remove ARI warnings, and
more importantly allow for easy finding of
function implementation (which was my reason
of adding that ARI rule).

  I hope everyone is OK with this.
I think that we do have lots of other occurrences 
of lines longer than 80 cols anyhow...
