DESCRIPTION

|

-----------

submodule doc: reorder introductory paragraphs
It's better to start the man page with a description of what
submodules actually are, instead of saying what they are not.
Reorder the paragraphs such that
- the first short paragraph introduces the submodule concept,
- the second paragraph highlights the usage of the submodule command,
- the third paragraph giving background information, and finally
- the fourth paragraph discusing alternatives such as subtrees and
remotes, which we don't want to be confused with.
This ordering deepens the knowledge on submodules with each paragraph.
First the basic questions like "How/what" will be answered, while the
underlying concepts will be taught at a later time.
Making sure it is not confused with subtrees and remotes is not really
enhancing knowledge of submodules itself, but rather painting the big
picture of git concepts, so you could also argue to have it as the second
paragraph. Personally I think this may confuse readers, specially
newcomers though.
Additionally to reordering the paragraphs, they have been slightly
reworded.

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.

submodule init: warn about falling back to a local path
When a submodule is initialized, the config variable 'submodule.<name>.url'
is set depending on the value of the same variable in the .gitmodules
file. When the URL indicates to be relative, then the url is computed
relative to its default remote. The default remote cannot be determined
accurately in all cases, such that it falls back to 'origin'.
The 'origin' remote may not exist, though. In that case we give up looking
for a suitable remote and we'll just assume it to be a local relative path.
This can be confusing to users as there is a lot of guessing involved,
which is not obvious to the user.
So in the corner case of assuming a local autoritative truth, warn the
user to lessen the confusion.
This behavior was introduced in 4d6893200 (submodule add: allow relative
repository path even when no url is set, 2011-06-06), which shared the
code with submodule-init and then ported to C in 3604242f080a (submodule:
port init from shell to C, 2016-04-15).
In case of submodule-add, this behavior makes sense in some use cases[1],
however for submodule-init there does not seem to be an immediate obvious
use case to fall back to a local submodule. However there might be, so
warn instead of die here.
While adding the warning, also clarify the behavior of relative URLs in
the documentation.

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.

submodule init: warn about falling back to a local path
When a submodule is initialized, the config variable 'submodule.<name>.url'
is set depending on the value of the same variable in the .gitmodules
file. When the URL indicates to be relative, then the url is computed
relative to its default remote. The default remote cannot be determined
accurately in all cases, such that it falls back to 'origin'.
The 'origin' remote may not exist, though. In that case we give up looking
for a suitable remote and we'll just assume it to be a local relative path.
This can be confusing to users as there is a lot of guessing involved,
which is not obvious to the user.
So in the corner case of assuming a local autoritative truth, warn the
user to lessen the confusion.
This behavior was introduced in 4d6893200 (submodule add: allow relative
repository path even when no url is set, 2011-06-06), which shared the
code with submodule-init and then ported to C in 3604242f080a (submodule:
port init from shell to C, 2016-04-15).
In case of submodule-add, this behavior makes sense in some use cases[1],
however for submodule-init there does not seem to be an immediate obvious
use case to fall back to a local submodule. However there might be, so
warn instead of die here.
While adding the warning, also clarify the behavior of relative URLs in
the documentation.

Update the registered submodules to match what the superproject
|
|
|
|
|
expects by cloning missing submodules and updating the working tree of
|
|
|
|
|
the submodules. The "updating" can be done in several ways depending
|
|
|
|
|
on command line options and the value of `submodule.<name>.update`
|
2016-12-28 00:43:09 +01:00

configuration variable. The command line option takes precedence over

2018-01-14 18:37:37 +01:00
|
|
|
the configuration variable. If neither is given, a 'checkout' is performed.
|
|
|
|
|
The 'update' procedures supported both from the command line as well as
|
|
|
|
|
through the `submodule.<name>.update` configuration are:
|
2015-03-02 23:57:58 +01:00
|
|
|
|
|
|
|
|
checkout;; the commit recorded in the superproject will be
|
2016-12-28 00:43:09 +01:00
|
|
|
checked out in the submodule on a detached HEAD.
|
2015-03-02 23:57:58 +01:00
|
|
|
+
|
|
|
|
|
If `--force` is specified, the submodule will be checked out (using
|
2018-01-14 18:37:37 +01:00
|
|
|
`git checkout --force`), even if the commit specified
|
2015-03-02 23:57:58 +01:00
|
|
|
in the index of the containing repository already matches the commit
|
|
|
|
|
checked out in the submodule.
|
|
|
|
|
|
|
|
|
|
rebase;; the current branch of the submodule will be rebased
|
2016-12-28 00:43:09 +01:00
|
|
|
onto the commit recorded in the superproject.
|
2015-03-02 23:57:58 +01:00
|
|
|
|
|
|
|
|
merge;; the commit recorded in the superproject will be merged
|
2016-12-28 00:43:09 +01:00
|

into the current branch in the submodule.
|
|
|
|
|
|
2018-01-14 18:37:37 +01:00

|
|
The following 'update' procedures are only available via the
|
|
|
|
|
`submodule.<name>.update` configuration variable:
|
2015-03-02 23:57:58 +01:00

|
argument (the sha1 of the commit recorded in the
|
2016-12-28 00:43:09 +01:00
|
|
|
superproject) is executed. When `submodule.<name>.update`
|
|
|
|
|
is set to '!command', the remainder after the exclamation mark
|
|

is the custom command.

$name is the name of the relevant submodule section in `.gitmodules`,

2018-05-09 02:29:50 +02:00

$sm_path is the path of the submodule as recorded in the immediate

superproject, $displaypath contains the relative path from the

|
$sha1 is the commit as recorded in the immediate
|
2018-05-09 02:29:50 +02:00

superproject, and $toplevel is the absolute path to the top-level

Note that to avoid conflicts with '$PATH' on Windows, the '$path'

Any submodules defined in the superproject but not checked out are

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 '|| :'

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 $toplevel variable
Gerrit uses the same interpretation for the setting, but because
Gerrit has direct access to the subproject repositories, it updates
the superproject repositories automatically when a subproject changes.
Gerrit also accepts the special value '.', which it expands into the
superproject's branch name.
Although the --remote functionality is using `submodule.<name>.branch`
slightly differently, the effect is the same. The foreach-pull
example uses the option to record the name of the local branch to
checkout before pulls. The tracking branch to be pulled is recorded
in `.git/modules/<name>/config`, which was initialized by the module
clone during `submodule add` or `submodule init`. Because the branch
name stored in `submodule.<name>.branch` was likely the same as the
branch name used during the initial `submodule add`, the same branch
will be pulled in each workflow.
Implementation details
======================
In order to ensure a current tracking branch state, `update --remote`
fetches the submodule's remote repository before calculating the
SHA-1. However, I didn't change the logic guarding the existing fetch:
if test -z "$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.

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.

When initializing submodules, a `.gitmodules` file in the top-level directory
|
2007-05-26 15:56:40 +02:00
|
|
|
of the containing repository is used to find the url of each submodule.

This file should be formatted in the same way as `$GIT_DIR/config`. The key

to each submodule url is "submodule.$name.url". See linkgit:gitmodules[5]
