a5099bb417 Use '-f' option to point to the .gitmodules file
'git config' has a '-f' option that takes the file to parse.
Using it rather than the environment variable seems more logical
and simplified.

f669ac0be9 git-submodule - possibly use branch name to describe a module
This changes the search logic for describing a submodule from:
- annotated tag
- any tag
- tag on a subsequent commit
- commit id

to

- annotated tag
- any tag
- tag on a subsequent commit
- local or remote branch
- commit id

The change is describing with respect to a branch before falling
back to the commit id. By itself, git-submodule will maintain submodules
as headless checkouts without ever making a local branch. In
general, such heads can always be described relative to the remote branch
regardless of existence of tags, and so provides a better fallback
summary than just the commit id.

This requires inserting an extra describe step as --contains is
incompatible with --all, but the latter can be used with --always
to fall back to a commit ID. Also, --contains implies --tags, so the
latter is not needed.

ba88a1fee4 Teach git-submodule.sh about the .git file
When git-submodule tries to detect 'active' submodules, it checks for the
existence of a directory named '.git'. This isn't good enough now that .git
can be a file pointing to the real $GIT_DIR so the tests are changed to

aadbe44f88 grep portability fix: don't use "-e" or "-q"
System V versions of grep (such as Solaris /usr/bin/grep)
don't understand either of these options. git's usage of
"grep -e pattern" fell into one of two categories:

 1. equivalent to "grep pattern". -e is only useful here if
    the pattern begins with a "-", but all of the patterns
    are hardcoded and do not begin with a dash.

 2. stripping comments and blank lines with

      grep -v -e "^$" -e "^#"

    We can fortunately do this in the affirmative as

      grep '^[^#]'

Uses of "-q" can be replaced with redirection to /dev/null.
In many tests, however, "grep -q" is used as "if this string
is in the expected output, we are OK". In this case, it is
fine to just remove the "-q" entirely; it simply makes the
"verbose" mode of the test slightly more verbose.

1cb639e6b0 git-submodule summary: show commit summary
This patch does the hard work to show submodule commit summary.

For a modified submodule, a series of commits will be shown with
the following command:

    git log --pretty='format:%m %s' \
        --first-parent sha1_src...sha1_dst

where the sha1_src is from the given super project commit and the
sha1_dst is from the index or working tree (switched by --cached).

For a deleted, added, or typechanged (blob<->submodule) submodule,
only one single newest commit from the existing end (for example,
src end for submodule deleted or type changed from submodule to blob)
will be shown.

If the src/dst sha1 for a submodule is missing in the submodule
directory, a warning will be issued except in two cases where the
submodule directory is deleted (type 'D') or typechanged to blob
(one case of type 'T').

In the title line for a submodule, the src/dst sha1 and the number
of commits (--first-parent) between the two commits will be shown.

The following example demonstrates most cases.

    Example: commit summary for modified submodules sm1-sm5.
    --------------------------------------------
    $ git submodule summary
    * sm1 354cd45...3f751e5 (4):

28f9af5d25 git-submodule summary: code framework
These patches teach git-submodule a new subcommand 'summary' to show
commit summary of checked out submodules between a given super project
commit (defaults to HEAD) and working tree (or index, when --cached is
given).

This patch just introduces the framework to find submodules which have
summary to show. A submodule will have summary if it falls into these
cases:

  - type 'M': modified and checked out    (1)
  - type 'A': added and checked out       (2)
  - type 'D': deleted
  - type 'T': typechanged (blob <-> submodule)

Notes:

  1. There may be modified but not checked out cases. In the case of a
     merge conflict, even if the submodule is not checked out, there may
	 be still a diff between index and HEAD on the submodule entry
	 (i.e. modified). The summary will not be show for such a submodule.
  2. A similar explanation applies to the added but not checked out case.

d4264ca323 git-submodule - Allow adding a submodule in-place
When working in the top-level project, it is useful to create a new
submodule as a git repo in a subdirectory, then add that submodule to
the top-level in place.

This patch allows "git submodule add <intended url> subdir" to add the
existing subdir to the current project.  The presumption is the user will
later push / clone the subdir to the <intended url> so that future
submodule init / updates will work.

Absent this patch, "git submodule add" insists upon cloning the subdir
from a repository at the given url, which is fine for adding an existing
project in, but less useful when adding a new submodule from scratch to an
existing project.  The former functionality remains, and the clone is
attempted if the subdir does not already exist as a valid git repo.

5c08dbbdf1 git-submodule: fix subcommand parser
The subcommand parser of "git submodule" made its subcommand
names reserved words.  As a consequence, a command like this:

    $ git submodule add init update

which is meant to add a submodule called 'init' at path 'update'
was misinterpreted as a request to invoke more than one mutually
incompatible subcommands and incorrectly rejected.

This patch fixes the issue by stopping the subcommand parsing at
the first subcommand word, to allow the sample command line
above to work as expected.

It also introduces the usual -- option disambiguator, so that a
submodule at path '-foo' can be updated with

    $ git submodule update -- -foo

without triggering an "unrecognized option -foo" error.

5188408057 Do not rely on the exit status of "unset" for unset variables
POSIX says that exit status "0" means that "unset" successfully unset
the variable.  However, it is kind of ambiguous if an environment
variable which was not set could be successfully unset.

At least the default shell on HP-UX insists on reporting an error in
such a case, so just ignore the exit status of "unset".

[Dscho: extended the patch to git-submodule.sh, as Junio realized that
 this is the only other place where we check the exit status of "unset".]

This allows a subproject's location to be specified and stored as relative
to the parent project's location (e.g., ./foo, or ../foo). This url is
stored in .gitmodules as given. It is resolved into an absolute url by
appending it to the parent project's url when the information is written
to .git/config (i.e., during submodule add for the originator, and
submodule init for a downstream recipient). This allows cloning of the
project to work "as expected" if the project is hosted on a different

822f7c7349 Supplant the "while case ... break ;; esac" idiom
A lot of shell scripts contained stuff starting with

	while case "$#" in 0) break ;; esac

and similar.  I consider breaking out of the condition instead of the
body od the loop ugly, and the implied "true" value of the
non-matching case is not really obvious to humans at first glance.  It
happens not to be obvious to some BSD shells, either, but that's
because they are not POSIX-compliant.  In most cases, this has been
replaced by a straight condition using "test".  "case" has the
advantage of being faster than "test" on vintage shells where "test"
is not a builtin.  Since none of them is likely to run the git
scripts, anyway, the added readability should be worth the change.

A few loops have had their termination condition expressed
differently.

537601ac74 git-submodule module_name: avoid using unwieldy "value_regexp" feature.
"module_name $path" function wants to look up a configuration

return the <modulename> found.  "git-config --get-regexp" is the
natural thing to use for this, but (1) its value matching has an
unfortunate "feature" that takes leading '!' specially, and (2)
its output needs to be parsed with sed to extract <modulename>
part anyway.

This changes the call to "git-config --get-regexp" not to use
the value-regexp part, and moves the "pick the one whose value
is $path" part to the downstream sed.

70c7ac22de Add git-submodule command
This command can be used to initialize, update and inspect submodules. It
uses a .gitmodules file, readable by git-config, in the top level directory
of the 'superproject' to specify a mapping between submodule paths and
repository url.

Example .gitmodules layout:

[module "git"]
	url = git://git.kernel.org/pub/scm/git/git.git

With this entry in .gitmodules (and a commit reference in the index entry for
the path "git"), the command 'git submodule init' will clone the repository
at kernel.org into the directory "git".

Known issues
============
There is currently no way to override the url found in the .gitmodules file,
except by manually creating the subproject repository. The place to fix this
in the script has a rather long comment about a possible plan.

Funny paths will be quoted in the output from git-ls-files, but git-submodule
does not attempt to unquote (or even detect the presence of) such paths.
