DESCRIPTION
|
|
|
|
|
-----------
|
2008-07-18 15:40:41 +02:00
|
|
|
Submodules allow foreign repositories to be embedded within
|
|
|
|
|
a dedicated subdirectory of the source tree, always pointed
|
|
|
|
|
at a particular commit.
|
|
|
|
|
|
|
|
|
|
They are not to be confused with remotes, which are meant mainly
|
|
|
|
|
for branches of the same project; submodules are meant for
|
|
|
|
|
different projects you would like to make part of your source tree,
|
|
|
|
|
while the history of the two projects still stays completely
|
|
|
|
|
independent and you cannot modify the contents of the submodule
|
|
|
|
|
from within the main project.
|
|
|
|
|
If you want to merge the project histories and want to treat the
|
|
|
|
|
aggregated whole as a single project from then on, you may want to
|
|
|
|
|
add a remote for the other project and use the 'subtree' merge strategy,
|
|
|
|
|
instead of treating the other project as a submodule. Directories
|
|
|
|
|
that come from both projects can be cloned and checked out as a whole
|
|
|
|
|
if you choose to go that route.
|
|
|
|
|
|
|
|
|
|
Submodules are composed from a so-called `gitlink` tree entry
|
|
|
|
|
in the main repository that refers to a particular commit object
|
|
|
|
|
within the inner repository that is completely separate.
|
2012-05-14 19:32:08 +02:00
|
|
|
A record in the `.gitmodules` (see linkgit:gitmodules[5]) file at the
|
|
|
|
|
root of the source tree assigns a logical name to the submodule and
|
|
|
|
|
describes the default URL the submodule shall be cloned from.
|
2008-07-18 15:40:41 +02:00
|
|
|
The logical name can be used for overriding this URL within your
|
|
|
|
|
local repository configuration (see 'submodule init').
|
|
|
|
|
|
|
|
|
|
This command will manage the tree entries and contents of the
|
|
|
|
|
gitmodules file for you, as well as inspect the status of your
|
|
|
|
|
submodules and update them.
|
|
|
|
|
When adding a new submodule to the tree, the 'add' subcommand
|
|
|
|
|
is to be used. However, when pulling a tree containing submodules,
|
|
|
|
|
these will not be checked out by default;
|
|
|
|
|
the 'init' and 'update' subcommands will maintain submodules
|
|
|
|
|
checked out and at appropriate revision in your working tree.
|
|
|
|
|
You can briefly inspect the up-to-date status of your submodules
|
|
|
|
|
using the 'status' subcommand and get a detailed overview of the
|
|
|
|
|
difference between the index and checkouts using the 'summary'
|
|
|
|
|
subcommand.

Add the given repository as a submodule at the given path

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.

This requires at least one argument: <repository>. The optional

|
|
|
|
argument <path> is the relative location for the cloned submodule
|

to exist in the superproject. If <path> is not given, the

|
|
"humanish" part of the source repository is used ("repo" for

"/path/to/repo.git" and "foo" for "host.xz:foo/.git").
|
2013-05-16 00:28:39 +02:00

The <path> is also used as the submodule's logical name in its

|

configuration entries unless `--name` is used to specify a logical name.

(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.

If you are only interested in changes of the currently initialized
|
|
|
|
|
submodules with respect to the commit recorded in the index or the HEAD,
|
|
|
|
|
linkgit:git-status[1] and linkgit:git-diff[1] will provide that information
|
|
|
|
|
too (and can also report changes to a submodule's work tree).

2013-05-16 00:28:39 +02:00
|
|
|
Initialize the submodules recorded in the index (which were
|
|
|
|
|
added and committed elsewhere) by copying submodule
|
|
|
|
|
names and urls from .gitmodules to .git/config.
|
|
|
|
|
Optional <path> arguments limit which submodules will be initialized.
|
2011-08-11 19:51:46 +02:00
|
|
|
It will also copy the value of `submodule.$name.update` into
|
|
|
|
|
.git/config.
|
2008-07-18 15:40:41 +02:00
|
|
|
The key used in .git/config is `submodule.$name.url`.
|
|
|
|
|
This command does not alter existing information in .git/config.
|
|
|
|
|
You can then customize the submodule clone URLs in .git/config
|
2010-01-07 17:49:12 +01:00
|
|
|
for your local setup and proceed to `git submodule update`;
|
|
|
|
|
you can also just use `git submodule update --init` without
|
2008-07-18 15:40:41 +02:00
|

|
the explicit 'init' step if you do not intend to customize

`submodule.$name` section from .git/config together with their work
|
|
|
|
|
tree. Further calls to `git submodule update`, `git submodule foreach`
|
|
|
|
|
and `git submodule sync` will skip any unregistered submodules until
|
|
|
|
|
they are initialized again, so use this command if you don't want to
|
|
|
|
|
have a local checkout of the submodule in your work tree anymore. If
|
|
|
|
|
you really want to remove a submodule from the repository and commit
|
|
|
|
|
that use linkgit:git-rm[1] instead.

|
|
|
checkout the commit specified in the index of the containing repository.
|
2011-08-01 22:49:21 +02:00

This will make the submodules HEAD be detached unless `--rebase` or

2012-06-22 22:03:01 +02:00

Evaluates an arbitrary shell command in each checked out submodule.
|
2010-05-21 18:10:10 +02:00

The command has access to the variables $name, $path, $sha1 and
|
|
|
|
|
$toplevel:
|
2009-08-16 03:10:08 +02:00
|
|
|
$name is the name of the relevant submodule section in .gitmodules,
|
2008-08-11 01:10:04 +02:00
|
|
|
$path is the name of the submodule directory relative to the
|
2010-05-21 18:10:10 +02:00
|
|
|
superproject, $sha1 is the commit as recorded in the superproject,
|
|
|
|
|
and $toplevel is the absolute path to the top-level of the superproject.
|
2008-08-11 01:10:04 +02:00
|
|
|
Any submodules defined in the superproject but not checked out are
|
2011-08-01 22:49:21 +02:00
|
|
|
ignored by this command. Unless given `--quiet`, foreach prints the name
|
2008-08-11 01:10:04 +02:00
|
|
|
of each submodule before evaluating the command.
|
2011-08-01 22:49:21 +02:00
|
|
|
If `--recursive` is given, submodules are traversed recursively (i.e.
|
2009-08-19 03:45:22 +02:00
|
|
|
the given shell command is evaluated in nested submodules as well).
|
2008-08-11 01:10:04 +02:00
|
|
|
A non-zero return from the command in any submodule causes
|
|

the processing to terminate. This can be overridden by adding '|| :'
|
|
|
|
|
to the end of the command.

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).

submodule update: add --remote for submodule's upstream changes
The current `update` command incorporates the superproject's gitlinked
SHA-1 ($sha1) into the submodule HEAD ($subsha1). Depending on the
options you use, it may checkout $sha1, rebase the $subsha1 onto
$sha1, or merge $sha1 into $subsha1. This helps you keep up with
changes in the upstream superproject.
However, it's also useful to stay up to date with changes in the
upstream subproject. Previous workflows for incorporating such
changes include the ungainly:
$ git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull'
With this patch, all of the useful functionality for incorporating
superproject changes can be reused to incorporate upstream subproject
updates. When you specify --remote, the target $sha1 is replaced with
a $sha1 of the submodule's origin/master tracking branch. If you want
to merge a different tracking branch, you can configure the
`submodule.<name>.branch` option in `.gitmodules`. You can override
the `.gitmodules` configuration setting for a particular superproject
by configuring the option in that superproject's default configuration
(using the usual configuration hierarchy, e.g. `.git/config`,
`~/.gitconfig`, etc.).
Previous use of submodule.<name>.branch
=======================================
Because we're adding a new configuration option, it's a good idea to
check if anyone else is already using the option. The foreach-pull
example above was described by Ævar in
commit f030c96d8643fa0a1a9b2bd9c2f36a77721fb61f

git-submodule foreach: Add $toplevel variable
Gerrit uses the same interpretation for the setting, but because
Gerrit has direct access to the subproject repositories, it updates
the superproject repositories automatically when a subproject changes.
Gerrit also accepts the special value '.', which it expands into the
superproject's branch name.
Although the --remote functionality is using `submodule.<name>.branch`
slightly differently, the effect is the same. The foreach-pull
example uses the option to record the name of the local branch to
checkout before pulls. The tracking branch to be pulled is recorded
in `.git/modules/<name>/config`, which was initialized by the module
clone during `submodule add` or `submodule init`. Because the branch
name stored in `submodule.<name>.branch` was likely the same as the
branch name used during the initial `submodule add`, the same branch
will be pulled in each workflow.
Implementation details
======================
In order to ensure a current tracking branch state, `update --remote`
fetches the submodule's remote repository before calculating the
SHA-1. However, I didn't change the logic guarding the existing fetch:
if test -z "$nofetch"
then
# Run fetch only if $sha1 isn't present or it
# is not reachable from a ref.
(clear_local_git_env; cd "$path" &&
( (rev=$(git rev-list -n 1 $sha1 --not --all 2>/dev/null) &&
test -z "$rev") || git-fetch)) ||
die "$(eval_gettext "Unable to fetch in submodule path '\$path'")"
fi
There will not be a double-fetch, because the new $sha1 determined
after the `--remote` triggered fetch should always exist in the
repository. If it doesn't, it's because some racy process removed it
from the submodule's repository and we *should* be re-fetching.

submodule update: add --remote for submodule's upstream changes
The current `update` command incorporates the superproject's gitlinked
SHA-1 ($sha1) into the submodule HEAD ($subsha1). Depending on the
options you use, it may checkout $sha1, rebase the $subsha1 onto
$sha1, or merge $sha1 into $subsha1. This helps you keep up with
changes in the upstream superproject.
However, it's also useful to stay up to date with changes in the
upstream subproject. Previous workflows for incorporating such
changes include the ungainly:
$ git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull'
With this patch, all of the useful functionality for incorporating
superproject changes can be reused to incorporate upstream subproject
updates. When you specify --remote, the target $sha1 is replaced with
a $sha1 of the submodule's origin/master tracking branch. If you want
to merge a different tracking branch, you can configure the
`submodule.<name>.branch` option in `.gitmodules`. You can override
the `.gitmodules` configuration setting for a particular superproject
by configuring the option in that superproject's default configuration
(using the usual configuration hierarchy, e.g. `.git/config`,
`~/.gitconfig`, etc.).
Previous use of submodule.<name>.branch
=======================================
Because we're adding a new configuration option, it's a good idea to
check if anyone else is already using the option. The foreach-pull
example above was described by Ævar in

git-submodule foreach: Add $toplevel variable
Gerrit uses the same interpretation for the setting, but because
Gerrit has direct access to the subproject repositories, it updates
the superproject repositories automatically when a subproject changes.
Gerrit also accepts the special value '.', which it expands into the
superproject's branch name.
Although the --remote functionality is using `submodule.<name>.branch`
slightly differently, the effect is the same. The foreach-pull
example uses the option to record the name of the local branch to
checkout before pulls. The tracking branch to be pulled is recorded
in `.git/modules/<name>/config`, which was initialized by the module
clone during `submodule add` or `submodule init`. Because the branch

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 - 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.
