Ramsay Jones 7f1b225153 t7400: add !CYGWIN prerequisite to 'add with \\ in path'
Commit cf9e55f494 ("submodule: prevent backslash expantion in submodule
names", 07-04-2017) added a test which creates a git repository with
some backslash characters in the name. On windows, where the backslash
character is a directory separator, it is not possible to create a
repository with the name 'sub\with\backslash'. (The NTFS filesystem would
probably allow it, but the win32 api does not). The MinGW and Git for
Windows versions of git actually create a repository called 'backslash'
in the sub-directory 'sub/with'.

On cygwin, however, due to the slightly schizophrenic treatment of the
backslash character by cygwin-git, this test fails at the 'git init'
stage. The git-init command does not recognise the directory separators
in the input path (eg. is_dir_sep('\\') is false), so it does not
attempt to create the leading directories 'sub/with'. (The call to
mkdir('sub\\with\\backslash') actually does recognise the directory
separators, but fails because the 'sub/with' directory doesn't exist).

In order to suppress the test failure (for now), add the !CYGWIN test
prerequisite.

Jeff King 627fde1025 submodule_init: die cleanly on submodules without url defined
When we init a submodule, we try to die when it has no URL
defined:

  url = xstrdup(sub->url);
  if (!url)
	  die(...);

But that's clearly nonsense. xstrdup() will never return
NULL, and if sub->url is NULL, we'll segfault.

These two bits of code need to be flipped, so we check
sub->url before looking at it.

Brandon Williams cf9e55f494 submodule: prevent backslash expantion in submodule names
When attempting to add a submodule with backslashes in its name 'git
submodule' fails in a funny way.  We can see that some of the
backslashes are expanded resulting in a bogus path:

git -C main submodule add ../sub\\with\\backslash
fatal: repository '/tmp/test/sub\witackslash' does not exist
fatal: clone of '/tmp/test/sub\witackslash' into submodule path

To solve this, convert calls to 'read' to 'read -r' in git-submodule.sh
in order to prevent backslash expantion in submodule names.

Brandon Williams bb62e0a99f clone: teach --recurse-submodules to optionally take a pathspec
Teach clone --recurse-submodules to optionally take a pathspec argument
which describes which submodules should be recursively initialized and
cloned.  If no pathspec is provided, --recurse-submodules will
recursively initialize and clone all submodules by using a default
pathspec of ".".  In order to construct more complex pathspecs,
--recurse-submodules can be given multiple times.

This also configures the 'submodule.active' configuration option to be
the given pathspec, such that any future invocation of `git submodule
update` will keep up with the pathspec.

Additionally the switch '--recurse' is removed from the Documentation as
well as marked hidden in the options array, to streamline the options
for submodules.  A simple '--recurse' doesn't convey what is being
recursed, e.g. it could mean directories or trees (c.f. ls-tree) In a
lot of other commands we already have '--recurse-submodules' to mean
recursing into submodules, so advertise this spelling here as the
genuine option.

Brandon Williams 3e7eaed016 submodule init: initialize active submodules
Teach `submodule init` to initialize submodules which have been
configured to be active by setting 'submodule.active' with a pathspec.

Now if no path arguments are given and 'submodule.active' is configured,
`init` will initialize all submodules which have been configured to be
active.  If no path arguments are given and 'submodule.active' is not
configured, then `init` will retain the old behavior of initializing all
submodules.

This allows users to record more complex patterns as it saves retyping
them whenever you invoke update.

Stefan Beller 619acfc78c submodule add: extend force flag to add existing repos
Currently the force flag in `git submodule add` takes care of possibly
ignored files or when a name collision occurs.

However there is another situation where submodule add comes in handy:
When you already have a gitlink recorded, but no configuration was
done (i.e. no .gitmodules file nor any entry in .git/config) and you
want to generate these config entries. For this situation allow
`git submodule add` to proceed if there is already a submodule at the
given path in the index.

Vasco Almeida 1edbaac3bb tests: use test_i18n* functions to suppress false positives
The test functions test_i18ncmp and test_i18ngrep pretend success if run
under GETTEXT_POISON. By using those functions to test output which is
correctly marked as translatable, enables one to detect if the strings
newly marked for translation are from plumbing output. If they are
indeed from plumbing, the test would fail, and the string should be
unmarked, since it is not seen by users.

Thus, it is productive to not have false positives when running the test
under GETTEXT_POISON. This commit replaces normal test functions by
their i18n aware variants in use-cases know to be correctly marked for
translation, suppressing false positives.

Stefan Beller f6a5279977 submodule deinit: require '--all' instead of '.' for all submodules
The discussion in [1] pointed out that '.' is a faulty suggestion as
there is a corner case where it fails:

> "submodule deinit ." may have "worked" in the sense that you would
> have at least one path in your tree and avoided this "nothing
> matches" most of the time.  It would have still failed with the
> exactly same error if run in an empty repository, i.e.
>
>        $ E=/var/tmp/x/empty && rm -fr "$E" && mkdir -p "$E" && cd "$E"
>        $ git init
>        $ rungit v2.6.6 submodule deinit .
>        error: pathspec '.' did not match any file(s) known to git.
>        Did you forget to 'git add'?
>        $ >file && git add file
>        $ rungit v2.6.6 submodule deinit .
>        $ echo $?
>        0

So instead of a pathspec add the '--all' option to deinit all submodules
and add a test to check for the corner case of an empty repository.

The code only needs to learn about the '--all' option and doesn't
require further changes as `git submodule--helper list "$@"` will list
all submodules when "$@" is empty.

"git submodule update --init --recursive" uses full path to refer to
the true location of the repository in the "gitdir:" pointer for
nested submodules; the command used to use relative paths.

This was reported by Norio Nomura in $gmane/290280.

This regression was introduced in 74703a1e4d (submodule: rewrite
`module_list` shell function in C, 2015-09-02), as we changed the
order of checking in new module listing to first check whether it is
a gitlin before feeding it to match_pathspec().  It used to be that
a pathspec that does not match any path were diagnosed as an error,
but the new code complains for a pathspec that does not match any
submodule path.

Arguably the new behaviour may give us a better diagnosis, but that
is inconsistent with the suggestion "deinit" gives, and also this
was an unintended accident.  The new behaviour hopefully can be
redesigned and implemented better in future releases, but for now,
switch these two checks to restore the same behavior as before.  In
an empty repository, giving the pathspec '.' will still get the same
"did not match" error, but that is the same bug we had before 1.7.0.

Doing:

  git config --file=foo ...

The latter is easier to read and slightly less error-prone,
because of issues with one-shot variables and shell

test_must_fail).

Note that we explicitly leave one case in t1300 which checks

John Keeping 2c63d6eb46 reset: handle submodule with trailing slash
When using tab-completion, a directory path will often end with a
trailing slash which currently confuses "git reset" when dealing with
submodules.  Now that we have parse_pathspec we can easily handle this
by simply adding the PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP flag.

To do this, we need to move the read_cache() call before the
parse_pathspec() call.  All of the existing paths through cmd_reset()
that do not die early already call read_cache() at some point, so there
is no performance impact to doing this in the common case.

Torsten Bögershausen 92b0c8bed0 Set core.precomposeunicode to true on e.g. HFS+
When core.precomposeunicode was introduced in 76759c7d,
it was set to false on a unicode decomposing file system like HFS+
to be compatible with older versions of Git.

The Mac OS users need to find out that this configuration exist
and change it manually from false to true.

A smoother workflow can be achieved,
so set core.precomposeunicode to true on a decomposing file system.

Jharrod LaFon 4b05440283 avoid segfault on submodule.*.path set to an empty "true"
Git fails due to a segmentation fault if a submodule path is empty.
Here is an example .gitmodules that will cause a segmentation fault:

    [submodule "foo-module"]
      path
      url = http://host/repo.git
    $ git status
    Segmentation fault (core dumped)

This is because the parsing of "submodule.*.path" is not prepared to
see a value-less "true" and assumes that the value is always
non-NULL (parsing of "ignore" has the same problem).

Fix it by checking the NULL-ness of value and complain with
config_error_nonbool().

Jens Lehmann 95c16418f0 rm: delete .gitmodules entry of submodules removed from the work tree
Currently using "git rm" on a submodule removes the submodule's work tree
from that of the superproject and the gitlink from the index. But the
submodule's section in .gitmodules is left untouched, which is a leftover
of the now removed submodule and might irritate users (as opposed to the
setting in .git/config, this must stay as a reminder that the user showed
interest in this submodule so it will be repopulated later when an older
commit is checked out).

Let "git rm" help the user by not only removing the submodule from the
work tree but by also removing the "submodule.<submodule name>" section
from the .gitmodules file and stage both. This doesn't happen when the
"--cached" option is used, as it would modify the work tree. This also
silently does nothing when no .gitmodules file is found and only issues a
warning when it doesn't have a section for this submodule. This is because
the user might just use plain gitlinks without the .gitmodules file or has
already removed the section by hand before issuing the "git rm" command
(in which case the warning reminds him that rm would have done that for
him). Only when .gitmodules is found and contains merge conflicts the rm
command will fail and tell the user to resolve the conflict before trying
again.

Also extend the man page to inform the user about this new feature. While
at it promote the submodule sub-section to a chapter as it made not much
sense under "REMOVING FILES THAT HAVE DISAPPEARED FROM THE FILESYSTEM".

In t7610 three uses of "git rm submod" had to be replaced with "git rm
--cached submod" because that test expects .gitmodules and the work tree
to stay untouched. Also in t7400 the tests for the remaining settings in
the .gitmodules file had to be changed to assert that these settings are
missing.

Fredrik Gustafsson 275cd184d5 Add --depth to submodule update/add
Add the --depth option to the add and update commands of "git submodule",
which is then passed on to the clone command. This is useful when the
submodule(s) are huge and you're not really interested in anything but
the latest commit.

Tests are added and some indention adjustments were made to conform to the
rest of the testfile on "submodule update can handle symbolic links in pwd".

Torsten Bögershausen bed9470489 t7400: test of UTF-8 submodule names pass under Mac OS
submodules with names using UTF-8 need core.precomposeunicode true
under Mac OS X, set it in the test case.

Improve the portability:

  - Not all shells on all OS may understand literal UTF-8 strings.
  - Use a help variable filled by printf, as we do it in e.g. t0050.

"strange names" can be called UTF-8, rephrase the heading.

While at it, unbreak &&-chain in the test, and use test_config.

John Keeping 091a6eb0fe submodule: drop the top-level requirement
Use the new rev-parse --prefix option to process all paths given to the
submodule command, dropping the requirement that it be run from the
top-level of the repository.

Since the interpretation of a relative submodule URL depends on whether
or not "remote.origin.url" is configured, explicitly block relative URLs
in "git submodule add" when not at the top level of the working tree.

Fredrik Gustafsson 74671241fd handle multibyte characters in name
Many "git submodule" operations do not work on a submodule at a path whose
name is not in ASCII.

This is because "git ls-files" is used to find which paths are bound to
submodules to the current working tree, and the output is C-quoted by default
for non ASCII pathnames.

Tell "git ls-files" to not C-quote its output, which is easier than unwrapping
C-quote ourselves.
