In preparation for unifying the handling of alt odb's and the normal
repo object directory, let's use a more neutral name. This patch is
purely mechanical, swapping the type name, and converting any variables
named "alt" to "odb". There should be no functional change, but it will
reduce the noise in subsequent diffs.

Using strip_suffix() lets us avoid repeating ourselves. It also makes
the handling of "/" a bit less subtle (we strip one less character than
we matched in order to leave it in place, but we can just as easily
include the "/" when we add more path components).

Some codepaths failed to form a proper URL when .gitmodules record

submodule helper: convert relative URL to absolute URL if needed

When the .gitmodules file is not available in the working tree, try
using the content from the index and from the current branch. This
covers the case when the file is part of the repository but for some
reason it is not checked out, for example because of a sparse checkout.
This makes it possible to use at least the 'git submodule' commands
which *read* the gitmodules configuration file without fully populating
the working tree.
Writing to .gitmodules will still require that the file is checked out,
so check for that before calling config_set_in_gitmodules_file_gently.
Add a similar check also in git-submodule.sh::cmd_add() to anticipate
the eventual failure of the "git submodule add" command when .gitmodules
is not safely writeable; this prevents the command from leaving the
repository in a spurious state (e.g. the submodule repository was cloned
but .gitmodules was not updated because
config_set_in_gitmodules_file_gently failed).
Moreover, since config_from_gitmodules() now accesses the global object
store, it is necessary to protect all code paths which call the function
against concurrent access to the global object store. Currently this
only happens in builtin/grep.c::grep_submodules(), so call
grep_read_lock() before invoking code involving
config_from_gitmodules().
Finally, add t7418-submodule-sparse-gitmodules.sh to verify that reading
from .gitmodules succeeds and that writing to it fails when the file is
not checked out.
NOTE: there is one rare case where this new feature does not work
properly yet: nested submodules without .gitmodules in their working
tree. This has been documented with a warning and a test_expect_failure
item in t7814, and in this case the current behavior is not altered: no
config is read.

The submodule helper update_clone called by "git submodule update",
clones submodules if needed. As submodules used to have the URL indicating
if they were active, the step to resolve relative URLs was done in the
"submodule init" step. Nowadays submodules can be configured active without
calling an explicit init, e.g. via configuring submodule.active.
When trying to obtain submodules that are set active this way, we'll
fallback to the URL found in the .gitmodules, which may be relative to the
superproject, but we do not resolve it, yet:
git clone https://gerrit.googlesource.com/gerrit
cd gerrit && grep url .gitmodules
url = ../plugins/codemirror-editor
...
git config submodule.active .
git submodule update
fatal: repository '../plugins/codemirror-editor' does not exist
fatal: clone of '../plugins/codemirror-editor' into submodule path '/tmp/gerrit/plugins/codemirror-editor' failed
Failed to clone 'plugins/codemirror-editor'. Retry scheduled
[...]
fatal: clone of '../plugins/codemirror-editor' into submodule path '/tmp/gerrit/plugins/codemirror-editor' failed
Failed to clone 'plugins/codemirror-editor' a second time, aborting
[...]
To resolve the issue, factor out the function that resolves the relative
URLs in "git submodule init" (in the submodule helper in the init_submodule
function) and call it at the appropriate place in the update_clone helper.

Introduce a helper function named is_writing_gitmodules_ok() to verify
that the .gitmodules file is safe to write.
The function name follows the scheme of is_staging_gitmodules_ok().
The two symbolic constants GITMODULES_INDEX and GITMODULES_HEAD are used
to get help from the C preprocessor in preventing typos, especially for
future users.
This is in preparation for a future change which teaches git how to read
.gitmodules from the index or from the current branch if the file is not
available in the working tree.
The rationale behind the check is that writing to .gitmodules requires
the file to be present in the working tree, unless a brand new
.gitmodules is being created (in which case the .gitmodules file would
not exist at all: neither in the working tree nor in the index or in the
current branch).
Expose the functionality also via a "submodule-helper config
--check-writeable" command, as git scripts may want to perform the check
before modifying submodules configuration.

When we clone a submodule, we call "git clone $url $path".
But there's nothing to say that those components can't begin
with a dash themselves, confusing git-clone into thinking
they're options. Let's pass "--" to make it clear what we
expect.
There's no test here, because it's actually quite hard to
make these names work, even with "git clone" parsing them
correctly. And we're going to restrict these cases even
further in future commits. So we'll leave off testing until
then; this is just the minimal fix to prevent us from doing
something stupid with a badly formed entry.

This reverts commit 7e25437d35a70791b345872af202eabfb3e1a8bc, reversing
changes made to 00624d608cc69bd62801c93e74d1ea7a7ddd6598.
v2.19.0-rc0~165^2~1 (submodule: ensure core.worktree is set after
update, 2018-06-18) assumes an "absorbed" submodule layout, where the
submodule's Git directory is in the superproject's .git/modules/
directory and .git in the submodule worktree is a .git file pointing
there. In particular, it uses $GIT_DIR/modules/$name to find the
submodule to find out whether it already has core.worktree set, and it
uses connect_work_tree_and_git_dir if not, resulting in
fatal: could not open sub/.git for writing
The context behind that patch: v2.19.0-rc0~165^2~2 (submodule: unset
core.worktree if no working tree is present, 2018-06-12) unsets
core.worktree when running commands like "git checkout
--recurse-submodules" to switch to a branch without the submodule. If
a user then uses "git checkout --no-recurse-submodules" to switch back
to a branch with the submodule and runs "git submodule update", this
patch is needed to ensure that commands using the submodule directly
are aware of the path to the worktree.
It is late in the release cycle, so revert the whole 3-patch series.
We can try again later for 2.20.

e98317508c0 (submodule: ensure core.worktree is set after update,
2018-06-18) was overly aggressive in calling connect_work_tree_and_git_dir
as that ensures both the 'core.worktree' configuration is set as well as
setting up correct gitlink file pointing at the git directory.
We do not need to check for the gitlink in this part of the cmd_update
in git-submodule.sh, as the initial call to update-clone will have ensured
that. So we can reduce the work to only (check and potentially) set the
'core.worktree' setting.
While at it move the check from shell to C as that proves to be useful in
a follow up patch, as we do not need the 'name' in shell now.

The 'mode' variable is not used in cmd_update for its original purpose,
rename it to 'dummy' as it only serves the purpose to abort quickly
documenting this knowledge.
The variable 'stage' is also not used any more in cmd_update, so remove it.
This went unnoticed as first each function used the commonly used
submodule listing, which was converted in 74703a1e4df (submodule: rewrite
`module_list` shell function in C, 2015-09-02). When cmd_update was
using its own function starting in 48308681b07 (git submodule update:
have a dedicated helper for cloning, 2016-02-29), its removal was missed.
A later patch in this series also touches the communication between
the submodule helper and git-submodule.sh, but let's have this as
a preparatory patch, as it eases the next patch, which stores the
raw data instead of the line printed for this communication.

Add a helper function to make it clearer that retrieving 'update-clone'
configuration from the .gitmodules file is a special case supported
solely for backward compatibility purposes.
This change removes one direct use of 'config_from_gitmodules' for
options not strictly related to submodules: "submodule.fetchjobs" does
not describe a property of a submodule, but a behavior of other commands
when dealing with submodules, so it does not really belong to the
.gitmodules file.
This is in the effort to communicate better that .gitmodules is not to
be used as a mechanism to store arbitrary configuration in the
repository that any command can retrieve.

Submodule "names" come from the untrusted .gitmodules file,
but we blindly append them to $GIT_DIR/modules to create our
on-disk repo paths. This means you can do bad things by
putting "../" into the name (among other things).
Let's sanity-check these names to avoid building a path that
can be exploited. There are two main decisions:
1. What should the allowed syntax be?
It's tempting to reuse verify_path(), since submodule
names typically come from in-repo paths. But there are
two reasons not to:
a. It's technically more strict than what we need, as
we really care only about breaking out of the
$GIT_DIR/modules/ hierarchy. E.g., having a
submodule named "foo/.git" isn't actually
dangerous, and it's possible that somebody has
manually given such a funny name.
b. Since we'll eventually use this checking logic in
fsck to prevent downstream repositories, it should
be consistent across platforms. Because
verify_path() relies on is_dir_sep(), it wouldn't
block "foo\..\bar" on a non-Windows machine.
2. Where should we enforce it? These days most of the
.gitmodules reads go through submodule-config.c, so
I've put it there in the reading step. That should
cover all of the C code.
We also construct the name for "git submodule add"
inside the git-submodule.sh script. This is probably
not a big deal for security since the name is coming
from the user anyway, but it would be polite to remind
them if the name they pick is invalid (and we need to
expose the name-checker to the shell anyway for our
test scripts).
This patch issues a warning when reading .gitmodules
and just ignores the related config entry completely.
This will generally end up producing a sensible error,
as it works the same as a .gitmodules file which is
missing a submodule entry (so "submodule update" will
barf, but "git clone --recurse-submodules" will print
an error but not abort the clone.
There is one minor oddity, which is that we print the
warning once per malformed config key (since that's how
the config subsystem gives us the entries). So in the
new test, for example, the user would see three
warnings. That's OK, since the intent is that this case
should never come up outside of malicious repositories
(and then it might even benefit the user to see the
message multiple times).
Credit for finding this vulnerability and the proof of
concept from which the test script was adapted goes to
Etienne Stalmans.
