Add a $toplevel variable accessible to `git submodule foreach`, it
contains the absolute path of the top level directory (where
.gitmodules is).
This makes it possible to e.g. read data in .gitmodules from within
foreach commands. I'm using this to configure the branch names I want
to track for each submodule:
git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull'
For a little history: This patch is borne out of my continuing fight
of trying to have Git track the branches of submodules, not just their
commits.
Obviously that's not how they work (they only track commits), but I'm
just interested in being able to do:
git submodule foreach 'git pull'
Of course that won't work because the submodule is in a disconnected
head, so I first have to connect it, but connect it *to what*.
For a while I was happy with this because as fate had it, it just so
happened to do what I meant:
git submodule foreach 'git checkout $(git describe --all --always) && git pull'
But then that broke down, if there's a tag and a branch the tag will
win out, and I can't git pull a branch:
$ git branch -a
* master
remotes/origin/HEAD -> origin/master
remotes/origin/master
$ git tag -l
release-0.0.6
$ git describe --always --all
release-0.0.6
So I figured that I might as well start tracking the branches I want
in .gitmodules itself:
[submodule "yaml-mode"]
path = yaml-mode
url = git://github.com/yoshiki/yaml-mode.git
branch = master
So now I can just do (as stated above):
git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull'
Maybe there's a less painful way to do *that* (I'd love to hear about
it). But regardless of that I think it's a good idea to be able to
know what the top-level is from git submodule foreach.

git-submodule inherits variables from the environment it is started in,
expects the internal variables init= and recursive= to have an empty
value, but doesn't initialize them appropriately. Thanks to the
selftests, this can be reproduced through
init=1 make test
recursive=1 make test
With this commit the variables are initialized, and the selftests
succeed even if these variables have some values in the environment.

Because log.decorate now shows decorations for --pretty=oneline,
we must explicitly turn it off when scripting. Otherwise,
users with log.decorate set will get cruft like:
$ git stash
Saved working directory and index state WIP on master:
2c1f7f5 (HEAD, master) commit subject
Instead of adding --no-decorate to the log command line,
let's just use the rev-list plumbing interface instead,
which does the right thing.
git-submodule has a similar call. Since it just counts the
commit lines, nothing is broken, but let's switch it, too,
for the sake of consistency and cleanliness.

git-submodule used to take care of clearing GIT_DIR whenever it operated
on a submodule index or configuration, but forgot to unset GIT_WORK_TREE
or other repo-local variables. This would lead to failures e.g. when
GIT_WORK_TREE was set.
This only happened in very unusual contexts such as operating on the
main worktree from outside of it, but since "git-gui: set GIT_DIR and
GIT_WORK_TREE after setup" (a9fa11fe5b) such failures could also
be provoked by invoking an external tool such as "git submodule update"
from the Git Gui in a standard setup.
Solve by using the newly introduced clear_local_git_env() shell function
to ensure that all repo-local environment variables are unset.

When invoking "git submodule summary" in an empty repo (which can be
indirectly done by setting status.submodulesummary = true), it currently
emits an error message (via "git diff-index") since HEAD points to an
unborn branch.
This patch adds handling of the HEAD-points-to-unborn-branch special case,
so that "git submodule summary" no longer emits this error message.
The patch also adds a test case that verifies the fix.

When the configuration variable status.submodulesummary is not 0 or
false, "git status" shows the submodule summary of the staged submodule
commits. But it did not show the summary of those commits not yet
staged in the supermodule, making it hard to see what will not be
committed.
The output of "submodule summary --for-status" has been changed from
"# Modified submodules:" to "# Submodule changes to be committed:" for
the already staged changes. "# Submodules changed but not updated:" has
been added for changes that will not be committed. This is much clearer
and consistent with the output for regular files.

If the user has exported the GREP_OPTIONS environment variable, the output
from "grep" and "egrep" in scripted Porcelains may be different from what
they expect. For example, we may want to count number of matching lines,
by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use.
The approach taken by this change to address this issue is to protect only
our own use of grep/egrep. Because we do not unset it at the beginning of
our scripts, hook scripts run from the scripted Porcelains are exposed to
the same insanity this environment variable causes when grep/egrep is used
to implement logic (e.g. "grep | wc -l"), and it is entirely up to the
hook scripts to protect themselves.
On the other hand, applypatch-msg hook may want to show offending words in
the proposed commit log message using grep to the end user, and the user
might want to set GREP_OPTIONS=--color to paint the match more visibly.
The approach to protect only our own use without unsetting the environment
variable globally will allow this use case.

'git submodule update --merge' merges the commit referenced by the
superproject into your local branch, instead of checking it out on
a detached HEAD.
As evidenced by the addition of "git submodule update --rebase", it
is useful to provide alternatives to the default 'checkout' behaviour
of "git submodule update". One such alternative is, when updating a
submodule to a new commit, to merge that commit into the current
local branch in that submodule. This is useful in workflows where
you want to update your submodule from its upstream, but you cannot
use --rebase, because you have downstream people working on top of
your submodule branch, and you don't want to disrupt their work.

The addition of "submodule.<name>.rebase" demonstrates the usefulness of
alternatives to the default behaviour of "git submodule update". However,
by naming the config variable "submodule.<name>.rebase", and making it a
boolean choice, we are artificially constraining future git versions that
may want to add _more_ alternatives than just "rebase".
Therefore, while "submodule.<name>.rebase" is not yet in a stable git
release, future-proof it, by changing it from
submodule.<name>.rebase = true/false
to
submodule.<name>.update = rebase/checkout
where "checkout" specifies the default behaviour of "git submodule update"
(checking out the new commit to a detached HEAD), and "rebase" specifies
the --rebase behaviour (where the current local branch in the submodule is
rebase onto the new commit). Thus .update == checkout is equivalent to
.rebase == false, and .update == rebase is equivalent to .rebase == true.
Finally, leaving .update unset is equivalent to leaving .rebase unset.
In future git versions, other alternatives to "git submodule update"
behaviour can be included by adding them to the list of allowable values
for the submodule.<name>.update variable.

'git submodule update --rebase' rebases your local branch on top of what
would have been checked out to a detached HEAD otherwise.
In some cases, detaching the HEAD when updating a submodule complicates
the workflow to commit to this submodule (checkout master, rebase, then
commit). For submodules that require frequent updates but infrequent
(if any) commits, a rebase can be executed directly by the git-submodule
command, ensuring that the submodules stay on their respective branches.

git submodule update --no-fetch makes it possible to use git submodule
update in complete offline mode by not fetching new revisions.
This does make sense in the following setup:
* There is an unstable and a stable branch in the super/master repository.
* The submodules might be at different revisions in the branches.
* You are at some place without internet connection ;)
With this patch it is now possible to change branches and update
the submodules to be at the recorded revision without online access.
Another advantage is that with -N the update operation is faster, because fetch is checking for new updates even if there was no fetch/pull on the super/master repository since the last update.
