In commit 9db31bdf (submodule: Add --force option for git submodule
update, 2011-04-01) we added the option to the implementation's usage
synopsis but forgot to add it to the synopsis in the command
documentation. Add the option to the synopsis in the same location it
is reported in usage and re-wrap the options to avoid long lines.

If you remove a submodule, in order to keep the repository so that
"git checkout" to an older commit in the superproject history can
resurrect the submodule, the real repository will stay in $GIT_DIR
of the superproject. A later "git submodule add $path" to add a
different submodule at the same path will fail. Diagnose this case
a bit better, and if the user really wants to add an unrelated
submodule at the same path, give the "--name" option to give it a
place in $GIT_DIR of the superproject that does not conflict with
the original submodule.

"git submodule add" initializes the name of a submodule to its path. This
was ok as long as the .git directory lived inside the submodule's work
tree, but since 1.7.8 it is stored in the .git/modules/<name> directory of
the superproject, making the submodule name survive the removal of the
submodule's work tree. This leads to problems when the user tries to add a
different submodule at the same path - and thus the same name - later, as
that will happily try to restore the submodule from the old repository
instead of the one the user specified and will lead to a checkout of the
wrong repository.
Add the new "--name" option to let the user provide a name for the
submodule. This enables the user to solve this conflict without having to
remove .git/modules/<name> by hand (which is no viable solution as it
makes it impossible to checkout a commit that records the old submodule
and populate it, as that will still check out the new submodule for the
same reason).
To achieve that the submodule's name is added to the parameter list of
the module_clone() helper function. This makes it possible to remove the
call of module_name() there because both callers of module_clone() already
know the name and can provide it as argument number two.

"git submodule" command DWIMs the command line and assumes a
unspecified action word for 'status' action. This is a UI mistake
that leads to a confusing behaviour. A mistyped command name is
instead treated as a request for 'status' of the submodule with that
name, e.g.
$ git submodule show
error: pathspec 'show' did not match any file(s) known to git.
Did you forget to 'git add'?
Stop DWIMming an unknown or mistyped subcommand name as pathspec
given to unspelled "status" subcommand. "git submodule" without any
argument is still interpreted as "git submodule status", but its
value is questionable.
Adjust t7400 to match, and stop advertising the default subcommand
being 'status' which does not help much in practice, other than
promoting laziness and confusion.

AsciiDoc versions since 5.0.6 treat a double-dash surrounded by spaces
(outside of verbatim environments) as a request to insert an em dash.
Such versions also treat the three-character sequence "\--", when not
followed by another dash, as a request to insert two literal minus
signs. Thus from time to time there have been patches to add
backslashes to AsciiDoc markup to escape double-dashes that are meant
to be represent '--' characters used literally on the command line;
see v1.4.0-rc1~174, Fix up docs where "--" isn't displayed correctly,
2006-05-05, for example.
AsciiDoc 6.0.3 (2005-04-20) made life harder by also treating
double-dashes without surrounding whitespace as markup for an em dash,
though only when formatting for backends other than the manpages
(e.g., HTML). Many pages needed to be changed to use a backslash
before the "--" in names of command-line flags like "--add" (see
v0.99.6~37, Update tutorial, 2005-08-30).
AsciiDoc 8.3.0 (2008-11-29) refined the em-dash rule to avoid that
requirement. Double-dashes without surrounding spaces are not
rendered as em dashes any more unless bordered on both sides by
alphanumeric characters. The unescaped markup for option names (e.g.,
"--add") works fine, and many instances of this style have leaked into
Documentation/; git's HTML documentation contains many spurious em
dashes when formatted by an older toolchain. (This patch will not
change that.)
The upshot: "--" as an isolated word and in phrases like "git
web--browse" must be escaped if it is not to be rendered as an em dash
by current asciidoc. Use "\--" to avoid such misformatting in
sentences in which "--" represents a literal double-minus command line
argument that separates options and revs from pathspecs, and use
"{litdd}" in cases where the double-dash is embedded in the command
name. The latter is just for consistency with v1.7.3-rc0~13^2 (Work
around em-dash handling in newer AsciiDoc, 2010-08-23).

directories, 2010-10-08) attempted to fix a bug where "git submodule sync"
command does not update the URL if the current superproject does not have
a checkout of the submodule.
However, it did so by unconditionally registering submodule.$name.url to
every submodule in the project, even the ones that the user has never
showed interest in at all by running 'git submodule init' command. This
caused subsequent 'git submodule update' to start cloning/updating submodules
that are not interesting to the user at all.
Update the code so that the URL is updated from the .gitmodules file only
for submodules that already have submodule.$name.url entries, i.e. the
ones the user has showed interested in having a checkout.

During a merge module_list returns conflicting submodules several times
(stage 1,2,3) which caused the submodules to be used multiple times in
git submodule init, sync, update and status command.
There are 5 callers of module_list; they all read (mode, sha1, stage,
path) tuple, and most of them care only about path. As a first level
approximation, it should be Ok (in the sense that it does not make things
worse than it currently is) to filter the duplicate paths from module_list
output, but some callers should change their behaviour when the merge in
the superproject still has conflicts.
Notice the higher-stage entries, and emit only one record from
module_list, but while doing so, mark the entry with "U" (not [0-3]) in
the $stage field and null out the SHA-1 part, as the object name for the
lowest stage does not give any useful information to the caller, and this
way any caller that uses the object name would hopefully barf. Then
update the codepaths for each subcommands this way:
- "update" should not touch the submodule repository, because we do not
know what commit should be checked out yet.
- "status" reports the conflicting submodules as 'U000...000' and does
not recurse into them (we might later want to make it recurse).
- The command called by "foreach" may want to do whatever it wants to do
by noticing the merged status in the superproject itself, so feed the
path to it from module_list as before, but only once per submodule.
- "init" and "sync" are unlikely things to do while the superproject is
still not merged, but as long as a submodule is there in $path, there
is no point skipping it. It might however want to take the merged
status of .gitmodules into account, but that is outside of the scope of
this topic.

The point of these sections is generally to:
1. Give credit where it is due.
2. Give the reader an idea of where to ask questions or
file bug reports.
But they don't do a good job of either case. For (1), they
are out of date and incomplete. A much more accurate answer
can be gotten through shortlog or blame. For (2), the
correct contact point is generally git@vger, and even if you
wanted to cc the contact point, the out-of-date and
incomplete fields mean you're likely sending to somebody
useless.
So let's drop the fields entirely from all manpages except
git(1) itself. We already point people to the mailing list
for bug reports there, and we can update the Authors section
to give credit to the major contributors and point to
shortlog and blame for more information.

Change `git submodule add' to add the new submodule <path> with `git
add --force'.
I keep my /etc in .git with a .gitignore that contains just
"*". I.e. `git status' will ignore everything that isn't in the tree
already. When I do:
git submodule add <url> hlagh
git-submodule will get as far as checking out the remote repository
into hlagh, but it'll die right afterwards when it fails to add the
new path:
The following paths are ignored by one of your .gitignore files:
hlagh
Use -f if you really want to add them.
fatal: no files added
Failed to add submodule 'hlagh'
Currently there's no way to add a submodule in this situation other
than to remove the ignored path from the .gitignore while I'm at it.
That's silly, when you run `git submodule add' you're explicitly
saying that you want to add something *new* to the repository. Instead
it should just add the path with `git add --force'.
Initially I implemented this by adding new -f and --force options to
`git submodule add'. But if the --force option isn't supplied it'll
get as far as cloning `hlagh', but won't add it.
So the first thing the user has to do is to remove `hlagh' and then
try again with the --force option.
That sucks, it should just add the path to begin with. I can't think
of any usecase where you've gone through the trouble of typing out
`git submodule add ..', but wish to be overriden by a `gitignore'. The
submodule semantics should be more like `git init', not `git add'.

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 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.
