PATCH 1/1 git status: Show detailed dirty status of submodules in long format

Since 1.7.0 there a three reasons a submodule is considered modified against the work tree: It contains new commits, modified content or untracked content. Lets show all reasons in the long format of git status, so the user can better asses the nature of the modification. This change does not affect the short and porcelain formats.

Two new members are added to "struct wt_status_change_data" to store the information gathered by run_diff_files(). wt-status.c uses the new flag DIFF_FORMAT_SUBMODULES to tell diff-lib.c it wants to get detailed dirty information about submodules.

So here is the promised patch teaching "git status" to show explicit dirtiness information for submodules. Instead of just showing a submodule as modified, it prints the reason(s) why the submodule is considered modified along with a new hint line (thanks to Sergio Callegari for bringing that last one up):

# Changed but not updated:

#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#   (commit or discard the untracked or modified content in submodules)

#
# modified: sub (new commits, modified content, untracked content)

(Note: The part in behind the submodule name is not colored like "modified:" and the name itself but like the header above for better visibility)

I am not so proud of DIFF_FORMAT_DIRTY_SUBMODULES, the new flag i introduced to tell run_diff_files() it should gather the information needed even if we don't want patch output. It isn't a "format" per se, but i couldn't come up with a better way to do this. Opinions?

Can we do this additional line only when there is a submodule involved in the changes? The whole point of "collect first and then print" is so that we can compute things like "has_deleted" before starting to emit any output to intelligently give an appropriate advice message, and it feels silly to say submodules to users who don't even use any submodule. I have a suspicion that the majority of users may not even know nor care what a submodule is.

It indeed does sound like DIFF_OPT_* than DIFF_FORMAT_*. In any case, we probably would want to have a small helper function that encapsulates this part that appear twice:

	changed = ce_match_stat(ce, &st, ce_option);
	if (S_ISGITLINK(ce->ce_mode)

		dirty_submodule = is_submodule_modified(ce->name);
		if (dirty_submodule)
			changed = 1;
	}

to something like

	changed = match_stat_with_submodule(&revs->diffopt, ce, &st,
        					ce_option, &dirty_submodule);

and the implementation of match_stat_with_submodule() a bit more heavily commented so that people will know what it is for.

PATCH v2 1/1 git status: Show detailed dirty status of submodules in long format

Two new members are added to "struct wt_status_change_data" to store the information gathered by run_diff_files(). wt-status.c uses the new flag DIFF_OPT_DIRTY_SUBMODULES to tell diff-lib.c it wants to get detailed dirty information about submodules.

A hint line for submodules is printed in the dirty header when dirty submodules are present.

Good point, the line will only be printed when necessary.

Right, using DIFF_OPT_DIRTY_SUBMODULES now.

This may be easier to read and maintain if you always added ", " at each step, and then backed up by two places before closing the thing with ')', without doing the sep = ", " in the middle.

This needs to be touched up as:

	color_fprintf(s->fp, color(WT_STATUS_HEADER, s), "%s", extra.buf);

just in case we may start adding some more free strings in extra.buf later. Also we tell the compiler that the third parameter to the function quacks like printf format string, and get a warning for passing an arbitrary string extra.buf to it.

PATCH v3 1/1 git status: Show detailed dirty status of submodules in long format

Since 1.7.0 there are three reasons a submodule is considered modified against the work tree: It contains new commits, modified content or untracked content. Lets show all reasons in the long format of git status, so the user can better asses the nature of the modification. This change does not affect the short and porcelain formats.

A hint line for submodules is printed in the dirty header when dirty submodules are present.

- Optimized handling of separator in output
- Added format string to color_fprintf()
