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

This patch adds handling of the HEAD-points-to-unborn-branch special case,
so that "git submodule summary" no longer emits this error message.

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

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

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.

git clone does not complain if a trailing '/' is included in the origin
URL, but doing so causes resolution of a submodule's URL relative to the
superproject to fail. Trailing /'s are likely when cloning locally using
tab-completion, so the slash may appear in either superproject or
submodule URL. So, ignore the trailing slash if it already exists in
the superproject's URL, and don't record one for the submodule (which
could itself have submodules...).
The problem I'm trying to fix is that a number of folks have
superprojects checked out where the recorded origin URL has a trailing
/, and a submodule has its origin in a directory sitting right next to
the superproject on the server. Thus, we have:
superproject url = server:/public/super
submodoule url = server:/public/sub1
However, in the checked out superproject's .git/config
[remote "origin"]
url = server:/public/super/
and for similar reasons, the submodule has its URL recorded in .gitmodules as
[submodule "sub"]
path = submodule1
url = ../sub1/
resolve_relative_url gets the submodule's recorded url as $1, which
the caller retrieved from .gitmodules, and retrieves the superprojects
origin from .git/config. So in this case resolve_relative_url has
that:
url = ../sub1/
remoteurl = server:/public/super/
So, without any patch, resolve_relative_url computes the submodule's URL as:
server:/public/super/sub1/
rather than
server:/public/sub1
In summary, it is essential that resolve_relative_url strip the
trailing / from the superproject's url before starting, and
beneficial if it assures that the result does not contain
a trailing / as the submodule may itself also be a superproject.

submodule foreach <command-list> will execute the list of commands in
each currently checked out submodule directory. The list of commands
is arbitrary as long as it is acceptable to sh. The variables '$path'
and '$sha1' are availble to the command-list, defining the submodule
path relative to the superproject and the submodules's commitID as
recorded in the superproject (this may be different than HEAD in the
submodule).
This utility is inspired by a number of threads on the mailing list
looking for ways to better integrate submodules in a tree and work
with them as a unit. This could include fetching a new branch in each
from a given source, or possibly checking out a given named branch in
each. Currently, there is no consensus as to what additional commands
should be implemented in the porcelain, requiring all users whose needs
exceed that of git-submodule to do their own scripting. The foreach
command is intended to support such scripting, and in particular does
no error checking and produces no output, thus allowing end users
complete control over any information printed out and over what
constitutes an error. The processing does terminate if the command-list
returns an error, but processing can easily be forced for all
submodules be terminating the list with ';true'.

This change makes "submodule add" much more strict in the arguments it
takes, and is intended to address confusion as recently noted on the
git-list. With this change, the required syntax is:
$ git submodule add URL path
Specifically, this eliminates the form
$ git submodule add URL
which was confused by more than one person as
$ git submodule add path
With this patch, the URL locating the submodule's origin repository can be
either an absolute URL, or (if it begins with ./ or ../) can express the
submodule's repository location relative to the superproject's origin.
This patch also eliminates a third form of URL, which was relative to the
superproject's top-level directory (not its repository). Any URL that was
neither absolute nor matched ./*|../* was assumed to point to a
subdirectory of the superproject as the location of the submodule's origin
repository. This URL form was confusing and does not seem to correspond
to an important use-case. Specifically, no-one has identified the need to
clone from a repository already in the superproject's tree, but if this is
needed it is easily done using an absolute URL: $(pwd)/relative-path. So,
no functionality is lost with this patch. (t6008-rev-list-submodule.sh did
rely upon this relative URL, fixed by using $(pwd).)
Following this change, there are exactly four variants of
submodule-add, as both arguments have two flavors:
URL can be absolute, or can begin with ./|../ and thus names the
submodule's origin relative to the superproject's origin.
Note: With this patch, "submodule add" discerns an absolute URL as
matching /*|*:*: e.g., URL begins with /, or it contains a :. This works
for all valid URLs, an absolute path in POSIX, as well as an absolute path
on Windows).
path can either already exist as a valid git repo, or will be cloned from
the given URL. The first form here eases creation of a new submodule in
an existing superproject as the submodule can be added and tested in-tree
before pushing to the public repository. However, the more usual form is
the second, where the repo is cloned from the given URL.
This specifically addresses the issue of
$ git submodule add a/b/c
attempting to clone from a repository at "a/b/c" to create a new module
in "c". This also simplifies description of "relative URL" as there is now
exactly *one* form: a URL relative to the parent's origin repo.

On Solaris it apparently fails to process input that doesn't end in a LF.
Consequently constructs like

cause re to be set to the empty string. Such a construct is used in

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.

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
reflect this.

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.

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):
< one line message for C

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.

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.

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.

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

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
server than when the subprojects were added.

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.

"module_name $path" function wants to look up a configuration
variable "submodule.<modulename>.path" whose value is $path, and
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.

To make a submodule effectively usable, the path and

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.
