565e135a1e Documentation: quote double-dash for AsciiDoc
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).

List of lines to fix found by grepping manpages for "(em".

ccee60862b submodule sync: do not auto-vivify uninteresting submodule
Earlier 33f072f (submodule sync: Update "submodule.<name>.url" for empty
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.

4d68932004 submodule add: allow relative repository path even when no url is set
Adding a submodule with a relative repository path did only succeed when
the superproject's default remote was set. But when that is unset, the
superproject is its own authoritative upstream, so lets use its working
directory as upstream instead.

This allows users to set up a new superpoject where the submodules urls
are configured relative to the superproject's upstream while its default
remote can be configured later.

9db31bdf5c submodule: Add --force option for git submodule update
By default git submodule update runs a simple checkout on submodules that
are not up-to-date. If the submodules contains modified or untracked
files, the command may exit sanely with an error:

  $ git submodule update
  error: Your local changes to the following files would be overwritten by
  checkout:
	  file
  Please, commit your changes or stash them before you can switch branches.
  Aborting
  Unable to checkout '1b69c6e55606b48d3284a3a9efe4b58bfb7e8c9e' in
  submodule path 'test1'

In order to reset a whole git submodule tree, a user has to run first 'git
submodule foreach --recursive git checkout -f' and then run 'git submodule
update'.

This patch adds a --force option for the update command (only used for
submodules without --rebase or --merge options). It passes the --force
option to git checkout which will throw away the local changes.

313ee0d69f submodule: process conflicting submodules only once
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.

48bb914ed6 doc: drop author/documentation sections from most pages
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.

Each page has a "This is part of git" footer, so people can
follow that to the main git manpage.

31991b0260 git submodule: add submodules with git add -f <path>
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'.

f030c96d86 git-submodule foreach: Add $toplevel variable
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.

0b444cdb19 Documentation: spell 'git cmd' without dash throughout
The documentation was quite inconsistent when spelling 'git cmd' if it
only refers to the program, not to some specific invocation syntax:
both 'git-cmd' and 'git cmd' spellings exist.

The current trend goes towards dashless forms, and there is precedent
in 647ac70 (git-svn.txt: stop using dash-form of commands.,
2009-07-07) to actively eliminate the dashed variants.

Replace 'git-cmd' with 'git cmd' throughout, except where git-shell,
git-cvsserver, git-upload-pack, git-receive-pack, and
git-upload-archive are concerned, because those really live in the
$PATH.

42b4917862 git-submodule: add support for --merge.
'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.

329484256e Rename submodule.<name>.rebase to submodule.<name>.update
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.

31ca3ac30f submodule: add --no-fetch parameter to update command
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.

2327f61ecc git-submodule: add "sync" command
When a submodule's URL changes upstream, existing submodules
will be out of sync since their remote."$origin".url will still
be set to the old value.

This adds a "git submodule sync" command that reads submodules'
URLs from .gitmodules and updates them accordingly.

19a31f9c1a git-submodule - Add 'foreach' subcommand
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'.

ec05df353c git-submodule - make "submodule add" more strict, and document it
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.

b1889c36d8 Documentation: be consistent about "git-" versus "git "
Since the git-* commands are not installed in $(bindir), using
"git-command <parameters>" in examples in the documentation is
not a good idea. On the other hand, it is nice to be able to
refer to each command using one hyphenated word. (There is no
escaping it, anyway: man page names cannot have spaces in them.)

This patch retains the dash in naming an operation, command,
program, process, or action. Complete command lines that can
be entered at a shell (i.e., without options omitted) are
made to use the dashless form.

The changes consist only of replacing some spaces with hyphens
and vice versa. After a "s/ /-/g", the unpatched and patched
versions are identical.

3240240ff4 Docs: Use "-l::\n--long\n" format in OPTIONS sections
The OPTIONS section of a documentation file contains a list
of the options a git command accepts.

Currently there are several variants to describe the case that
different options (almost) do the same in the OPTIONS section.

Some are:

 -f, --foo::
 -f|--foo::
 -f | --foo::

But AsciiDoc has the special form:

 -f::
 --foo::

This patch applies this form to the documentation of the whole git suite,
and removes useless em-dash prevention, so \--foo becomes --foo.

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.

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
server than when the subprojects were added.

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.
