[PATCH 0/9] Extend use of parse_options()

From: Michele Ballabio <hidden>
Date: 2016-06-15 22:45:00

These patches spread the use of parse_options() to some more commands.
I tried to come up with a short description for every option, but
I'm not sure I fully succeeded. In particular, the option "sparse"
in builtin-rev-list.c has no description.

Michele Ballabio (9):
  builtin-verify-tag.c: use parse_options()
  builtin-write-tree.c: use parse_options()
  builtin-prune-packed.c: use parse_options()
  builtin-ls-tree.c: use parse_options()
  builtin-rev-list.c: use parse_options()
  builtin-init-db.c: use parse_options()
  builtin-checkout-index.c: use parse_options()
  builtin-fetch-pack.c: use parse_options()
  builtin-mailinfo.c: use parse_options()

It works because PERM_UMASK == 0, but it is a side effect. Don't you think?

It seems this is broken since the C rewrite: "git verify-tag -v" just do
nothing instead of printing usage message.

Moving the if() after parse_options() call with s/argc == 1/argc == 0/
should do the trick.

I do not see how that would be any safer.

It works because PERM_UMASK == 0, but it is a side effect. Don't you think?

Then the callback is wrong, too.  I think, however, that it is by design, 
and correct.

We rely on shared_repository == 0 for non-shared repositories _almost 
everywhere_.

Why?  Doesn't make it more readable, I think.  I'd rather have 3 lines 
less.

Are you sure the default value is really used here?

Yes. Perhaps I don't understand your question. Can you explain what you mean?

Also, perhaps we can play it safer by avoiding changing "share_repository"
directly.

$ git init -> shared_repository == PERM_UMASK
$ git init --shared --no-shared -> shared_repository == 0

It works because PERM_UMASK == 0, but it is a side effect. Don't you think?

Would you like this better, with PARSE_OPT_NONEG?

+               { OPTION_CALLBACK, 0, "shared", &shared_repository,
+                 "permissions", "set up a shared repository",
+                 PARSE_OPT_OPTARG | PARSE_OPT_NONEG, parse_opt_shared_cb, PERM_GROUP },

Or do you prefer changing the callback like this:

+static int parse_opt_shared_cb(const struct option *opt, const char *arg,
+                              int unset)
+{
+       *(int *)(opt->value) = unset ? PERM_UMASK : git_config_perm("arg", arg);
+       return 0;
+}

quoted

+		OPT_BIT('q', "quiet", &flags, "be quiet", INIT_DB_QUIET),

OPT__QUIET(&quiet),

if (quiet)
	flags |= INIT_DB_QUIET;

to use the same quiet option everywhere?

I thought about it and decided against ;)
And it's one line vs four (counting "int quiet = 0;"). But I see your point.

I thought there is an OPT_BIT?

OPT_BIT is for flags and bitmasks, not for bitfields.

Since you can't get the address of a bitfield member, a function that
wants to change its value needs to know its name.  Switching to bitmasks
would make the option parsing code look cleaner, but you'd have to
change all those bitfield accesses to explicit bitmask operations, e.g.:

	if (state.force)
		state.force = 0;

vs.

	if (state.flags & CHECKOUT_FORCE)
		state.flags &= ~CHECKOUT_FORCE;

In the case of struct checkout, though, we could simply make the
bitfield members full ints, because there are only a few instances of
this structure in memory at any given time.  Wasting a few bytes of RAM
in order to gain much simpler code is OK in this case, I think.
OPT_BOOLEAN looks a lot nicer than a callback.

Johannes Schindelin a écrit :

No.  "setup" is a noun.

Right, sorry.

We rely on shared_repository == 0 for non-shared repositories _almost 
everywhere_.

I think we rely on the fact that PERM_UMASK == 0 and not on the value
of shared_repository. Not the same thing.

That said, perhaps you are right: it is harmless.

quoted

+		OPT_BIT('q', "quiet", &flags, "be quiet", INIT_DB_QUIET),

OPT__QUIET(&quiet),

Why?  Doesn't make it more readable, I think.  I'd rather have 3 lines 
less.

Hum.

Yes. Perhaps I don't understand your question. Can you explain what you mean?

If I read the code correctly in parse-options.c, with OPTION_CALLBACK, the
default value is not "automatically" used. You can use it in your callback
if you want, but because you don't, I think it's never used.

Would you like this better, with PARSE_OPT_NONEG?

No, I'm fine with the negated option.

Or do you prefer changing the callback like this:

+static int parse_opt_shared_cb(const struct option *opt, const char *arg,
+                              int unset)
+{
+       *(int *)(opt->value) = unset ? PERM_UMASK : git_config_perm("arg", arg);
+       return 0;
+}

I think it's better but what I suggested is more something like:

static int parse_opt_shared_cb(const struct option *opt, const char *arg,
			       int unset)
{
	*(int *)(opt->value) = unset ? -1 : git_config_perm("arg", arg);
	return 0;
}

int shared = -1;

{ OPTION_CALLBACK, 0, "shared", &shared,
	"permissions", "setup as shared repository",
	PARSE_OPT_OPTARG, parse_perm_callback },

if (shared >= 0)
	shared_repository = shared;

This way we do not change shared_repository during parsing, so we do not
loose the initial value.

But it seems nobody care about this kind of details, so perhaps, you can
just ignore this suggestion.

Olivier.

Yes. I only wanted the changes to be minimal, and only affect the option
parsing. In this sense, I still think the old patch is better. Here it is
the one you suggested (maybe Johannes suggested the same, but I didn't
understand :).

But it seems nobody care about this kind of details, so perhaps, you can

I might be wrong, but shared_repository is initialized to PERM_UMASK and
does not change before parse_options() is called, so this is not much
useful.

That would be a bugfix.  As such, it belongs into a different commit.

I thought, for that kind of trivial bug that probably never hit anyone, 
a line in the commit message was enough.

So bisectability goes down the gutter?

We rely on shared_repository == 0 for non-shared repositories _almost 
everywhere_.

I think we rely on the fact that PERM_UMASK == 0 and not on the value of 
shared_repository. Not the same thing.

Just look at all the cases where we ask for "if (shared_repository)".  
And then look where PERM_UMASK is assigned to.  It _is_ the same thing.

Hth,

[PATCH] builtin-verify-tag: fix -v option parsing

From: Olivier Marin <hidden>
Date: 2016-06-15 22:45:03

From: Olivier Marin <redacted>

Since the C rewrite, "git verify-tag -v" just does nothing instead of
printing the usage message with an error. This patch fix the regression.

Maybe a better solution would be to convert (trivially) to 
parse-options...

I am very puzzled.

You first asked me to do a separate commit with just the fix and now
you seem to want the fix with the conversion...

What do you mean by "trivially"?

Olivier.

Sorry.  It was not obvious to myself when I asked for a separate patch 
that the fix would fall out of the conversion to parse-options.

My fault,
