Add an optional argument for --color options
Make git-branch, git-show-branch, git-grep, and all the diff-based
programs accept an optional argument <when> for --color. The argument
is a colorbool: "always", "never", or "auto". If no argument is given,
"always" is used; --no-color is an alias for --color=never. This makes
the command-line interface consistent with other GNU tools, such as `ls'
and `grep', and with the git-config color options. Note that, without
an argument, --color and --no-color work exactly as before.
To implement this, two internal changes were made:
1. Allow the first argument of git_config_colorbool() to be NULL,
in which case it returns -1 if the argument isn't "always", "never",
or "auto".
2. Add OPT_COLOR_FLAG(), OPT__COLOR(), and parse_opt_color_flag_cb()
to the option parsing library. The callback uses
git_config_colorbool(), so color.h is now a dependency
of parse-options.c.

parse-options: allow git commands to invent new option types
parse-options provides a variety of option behaviors, including
OPTION_CALLBACK, which should take care of just about any sane
behavior. All supported behaviors obey the following constraint:
A --foo option can only accept (and base its behavior on)
one argument, which would be the following command-line
argument in the "unsticked" form.
Alas, some existing git commands have options that do not obey that
constraint. For example, update-index --cacheinfo takes three
arguments, and update-index --resolve takes all later parameters as
arguments.
Introduces an OPTION_LOWLEVEL_CALLBACK backdoor to parse-options so
such option types can be supported without tempting inventors of other
commands through mention in the public API. Commands can set the
callback field to a function accepting three arguments: the option
parsing context, the option itself, and a flag indicating whether the
the option was negated. When the option is encountered, that function
is called to take over from get_value(). The return value should be
zero for success, -1 for usage errors.
Thanks to Stephen Boyd for API guidance.

parse-options: deprecate OPT_BOOLEAN
It is natural to expect that an option defined with OPT_BOOLEAN() could be
used in this way:
int option = -1; /* unspecified */
struct option options[] = {
OPT_BOOLEAN(0, "option", &option, "set option"),
OPT_END()
};
parse_options(ac, av, prefix, options, usage, 0);
if (option < 0)
... do the default thing ...
else if (!option)
... --no-option was given ...
else
... --option was given ...
to easily tell three cases apart:
- There is no mention of the `--option` on the command line;
- The variable is positively set with `--option`; or
- The variable is explicitly negated with `--no-option`.
Unfortunately, this is not the case. OPT_BOOLEAN() increments the variable
every time `--option` is given, and resets it to zero when `--no-option`
is given.
As a first step to remedy this, introduce a true boolean OPT_BOOL(), and
rename OPT_BOOLEAN() to OPT_COUNTUP(). To help transitioning, OPT_BOOLEAN
and OPTION_BOOLEAN are defined as deprecated synonyms to OPT_COUNTUP and
OPTION_COUNTUP respectively.
This is what db7244b (parse-options new features., 2007-11-07) from four
years ago started by marking OPTION_BOOLEAN as "INCR would have been a
better name".
Some existing users do depend on the count-up semantics; for example,
users of OPT__VERBOSE() could use it to raise the verbosity level with
repeated use of `-v` on the command line, but they probably should be
rewritten to use OPT__VERBOSITY() instead these days. I suspect that some
users of OPT__FORCE() may also use it to implement different level of
forcibleness but I didn't check.
On top of this patch, here are the remaining clean-up tasks that other
people can help:
- Look at each hit in "git grep -e OPT_BOOLEAN"; trace all uses of the
value that is set to the underlying variable, and if it can proven that
the variable is only used as a boolean, replace it with OPT_BOOL(). If
the caller does depend on the count-up semantics, replace it with
OPT_COUNTUP() instead.
- Same for OPTION_BOOLEAN; replace it with OPTION_SET_INT and arrange to
set 1 to the variable for a true boolean, and otherwise replace it with
OPTION_COUNTUP.
- Look at each hit in "git grep -e OPT__VERBOSE -e OPT__QUIET" and see if
they can be replaced with OPT__VERBOSITY().
I'll follow this message up with a separate patch as an example.

parse-options: deprecate OPT_BOOLEAN
It is natural to expect that an option defined with OPT_BOOLEAN() could be
used in this way:
int option = -1; /* unspecified */
struct option options[] = {
OPT_BOOLEAN(0, "option", &option, "set option"),
OPT_END()
};
parse_options(ac, av, prefix, options, usage, 0);
if (option < 0)
... do the default thing ...
else if (!option)
... --no-option was given ...
else
... --option was given ...
to easily tell three cases apart:
- There is no mention of the `--option` on the command line;
- The variable is positively set with `--option`; or
- The variable is explicitly negated with `--no-option`.
Unfortunately, this is not the case. OPT_BOOLEAN() increments the variable
every time `--option` is given, and resets it to zero when `--no-option`
is given.
As a first step to remedy this, introduce a true boolean OPT_BOOL(), and
rename OPT_BOOLEAN() to OPT_COUNTUP(). To help transitioning, OPT_BOOLEAN
and OPTION_BOOLEAN are defined as deprecated synonyms to OPT_COUNTUP and
OPTION_COUNTUP respectively.
This is what db7244b (parse-options new features., 2007-11-07) from four
years ago started by marking OPTION_BOOLEAN as "INCR would have been a
better name".
Some existing users do depend on the count-up semantics; for example,
users of OPT__VERBOSE() could use it to raise the verbosity level with
repeated use of `-v` on the command line, but they probably should be
rewritten to use OPT__VERBOSITY() instead these days. I suspect that some
users of OPT__FORCE() may also use it to implement different level of
forcibleness but I didn't check.
On top of this patch, here are the remaining clean-up tasks that other
people can help:
- Look at each hit in "git grep -e OPT_BOOLEAN"; trace all uses of the
value that is set to the underlying variable, and if it can proven that
the variable is only used as a boolean, replace it with OPT_BOOL(). If
the caller does depend on the count-up semantics, replace it with
OPT_COUNTUP() instead.
- Same for OPTION_BOOLEAN; replace it with OPTION_SET_INT and arrange to
set 1 to the variable for a true boolean, and otherwise replace it with
OPTION_COUNTUP.
- Look at each hit in "git grep -e OPT__VERBOSE -e OPT__QUIET" and see if
they can be replaced with OPT__VERBOSITY().
I'll follow this message up with a separate patch as an example.

git on Mac OS and precomposed unicode
Mac OS X mangles file names containing unicode on file systems HFS+,
VFAT or SAMBA. When a file using unicode code points outside ASCII
is created on a HFS+ drive, the file name is converted into
decomposed unicode and written to disk. No conversion is done if
the file name is already decomposed unicode.
Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same
result as open("\x41\xcc\x88",...) with a decomposed "Ä".
As a consequence, readdir() returns the file names in decomposed
unicode, even if the user expects precomposed unicode. Unlike on
HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in
precomposed unicode, but readdir() still returns file names in
decomposed unicode. When a git repository is stored on a network
share using SAMBA, file names are send over the wire and written to
disk on the remote system in precomposed unicode, but Mac OS X
readdir() returns decomposed unicode to be compatible with its
behaviour on HFS+ and VFAT.
The unicode decomposition causes many problems:
- The names "git add" and other commands get from the end user may
often be precomposed form (the decomposed form is not easily input
from the keyboard), but when the commands read from the filesystem
to see what it is going to update the index with already is on the
filesystem, readdir() will give decomposed form, which is different.
- Similarly "git log", "git mv" and all other commands that need to
compare pathnames found on the command line (often but not always
precomposed form; a command line input resulting from globbing may
be in decomposed) with pathnames found in the tree objects (should
be precomposed form to be compatible with other systems and for
consistency in general).
- The same for names stored in the index, which should be
precomposed, that may need to be compared with the names read from
readdir().
NFS mounted from Linux is fully transparent and does not suffer from
the above.
As Mac OS X treats precomposed and decomposed file names as equal,
we can
- wrap readdir() on Mac OS X to return the precomposed form, and
- normalize decomposed form given from the command line also to the
precomposed form,
to ensure that all pathnames used in Git are always in the
precomposed form. This behaviour can be requested by setting
"core.precomposedunicode" configuration variable to true.
The code in compat/precomposed_utf8.c implements basically 4 new
functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(),
precomposed_utf8_closedir() and precompose_argv(). The first three
are to wrap opendir(3), readdir(3), and closedir(3) functions.
The argv[] conversion allows to use the TAB filename completion done
by the shell on command line. It tolerates other tools which use
readdir() to feed decomposed file names into git.
When creating a new git repository with "git init" or "git clone",
"core.precomposedunicode" will be set "false".
The user needs to activate this feature manually. She typically
sets core.precomposedunicode to "true" on HFS and VFAT, or file
systems mounted via SAMBA.

- These files have symbols which should be marked static since they're
only file scope:
submodule.c:12, diff.c:631, replace_object.c:92, submodule.c:13,
submodule.c:14, trace.c:78, transport.c:195, transport-helper.c:79,
unpack-trees.c:19, url.c:3, url.c:18, url.c:104, url.c:117, url.c:123,
url.c:129, url.c:136, thread-utils.c:21, thread-utils.c:48
- These files redeclare symbols to be different types:
builtin/index-pack.c:210, parse-options.c:564, parse-options.c:571,
usage.c:49, usage.c:58, usage.c:63, usage.c:72
- These files use a literal integer 0 when they really should use a NULL
pointer:
daemon.c:663, fast-import.c:2942, imap-send.c:1072, notes-merge.c:362
While we're in the area, clean up some unused #includes in builtin files
(mostly exec_cmd.h).
