Convert lookup_commit, lookup_commit_or_die,
lookup_commit_reference, and lookup_commit_reference_gently to take
struct object_id arguments.
Introduce a temporary in parse_object buffer in order to convert this
function. This is required since in order to convert parse_object and
parse_object_buffer, lookup_commit_reference_gently and
lookup_commit_or_die would need to be converted. Not introducing a
temporary would therefore require that lookup_commit_or_die take a
struct object_id *, but lookup_commit would take unsigned char *,
leaving a confusing and hard-to-use interface.
parse_object_buffer will lose this temporary in a later patch.

Teach "push --recurse-submodules" to propagate, if given a name as remote, the
provided remote and refspec recursively to the pushes performed in the
submodules. The push will therefore only succeed if all submodules have a
remote with such a name configured.
Note that "push --recurse-submodules" with a path or URL as remote will not
propagate the remote or refspec and instead use the default remote and refspec
configured in the submodule, preserving the current behavior.

This happens, because we do not properly initialize the environment
in which the diff is run in the submodule. That means we inherit the
environment from the main process, which sets environment variables.
(Apparently we do set environment variables which we do not set
when not in a submodules, i.e. the .git directory is linked)
This commit, just like fd47ae6a5b (diff: teach diff to display
submodule difference with an inline diff, 2016-08-31) introduces bad
test code (i.e. hard coded hash values), which will be cleanup up in

These calls to snprintf should always succeed, because their
input is small and fixed. Let's use xsnprintf to make sure
this is the case (and to make auditing for actual truncation
easier).
These could be candidates for turning into heap buffers, but
they fall into a few broad categories that make it not worth
doing:
- formatting single numbers is simple enough that we can
see the result should fit
- the size of a sha1 is likewise well-known, and I didn't
want to cause unnecessary conflicts with the ongoing
process to convert these constants to GIT_MAX_HEXSZ
- the interface for curl_errorstr is dictated by curl

Suppose I have a superproject 'super', with two submodules 'super/sub'
and 'super/sub1'. 'super/sub' itself contains a submodule
'super/sub/subsub'. Now suppose I run, from within 'super':
echo hi >sub/subsub/stray-file
echo hi >sub1/stray-file
Currently we get would see the following output in git-status:
git status --short
m sub
? sub1
With this patch applied, the untracked file in the nested submodule is
displayed as an untracked file on the 'super' level as well.
git status --short
? sub
? sub1
This doesn't change the output of 'git status --porcelain=1' for nested
submodules, because its output is always ' M' for either untracked files
or local modifications no matter the nesting level of the submodule.
'git status --porcelain=2' is affected by this change in a nested
submodule, though. Without this patch it would report the direct submodule
as modified and having no untracked files. With this patch it would report
untracked files. Chalk this up as a bug fix.
This bug fix also affects the default output (non-short, non-porcelain)
of git-status, which is not tested here.

Migrate 'is_submodule_modified' to the new porcelain format of
git-status. This conversion attempts to convert faithfully, i.e.
the behavior ought to be exactly the same.
As the output in the parsing only distinguishes between untracked files
and the rest, this is easy to port to the new format, as we only
need to identify untracked files and the rest is handled in the "else"
case.
untracked files are indicated by only a single question mark instead of
two question marks, so the conversion is easy.

Instead of implementing line reading yet again, make use of our beautiful
library function to read one line. By using strbuf_getwholeline instead
of strbuf_read, we avoid having to allocate memory for the entire child
process output at once. That is, we limit maximum memory usage.
Also we can start processing the output as it comes in, no need to
wait for all of it.
Once we know all information that we care about, we can terminate
the child early. In that case we do not care about its exit code as well.
By just closing our side of the pipe the child process will get a SIGPIPE
signal, which it will not report nor do we report it in finish_command,
ac78663b0d (run-command: don't warn on SIGPIPE deaths, 2015-12-29).

Currently the submodule.<name>.url config option is used to determine if
a given submodule is of interest to the user. This ends up being
cumbersome in a world where we want to have different submodules checked
out in different worktrees or a more generalized mechanism to select
which submodules are of interest.
In a future with worktree support for submodules, there will be multiple
working trees, each of which may only need a subset of the submodules
checked out. The URL (which is where the submodule repository can be
obtained) should not differ between different working trees.
It may also be convenient for users to more easily specify groups of
submodules they are interested in as opposed to running "git submodule
init <path>" on each submodule they want checked out in their working
tree.
To this end two config options are introduced, submodule.active and
submodule.<name>.active. The submodule.active config holds a pathspec
that specifies which submodules should exist in the working tree. The
submodule.<name>.active config is a boolean flag used to indicate if
that particular submodule should exist in the working tree.
Its important to note that submodule.active functions differently than
the other configuration options since it takes a pathspec. This allows
users to adopt at least two new workflows:
1. Submodules can be grouped with a leading directory, such that a
pathspec e.g. 'lib/' would cover all library-ish modules to allow
those who are interested in library-ish modules to set
"submodule.active = lib/" just once to say any and all modules in
'lib/' are interesting.
2. Once the pathspec-attribute feature is invented, users can label
submodules with attributes to group them, so that a broad pathspec
with attribute requirements, e.g. ':(attr:lib)', can be used to say
any and all modules with the 'lib' attribute are interesting.
Since the .gitattributes file, just like the .gitmodules file, is
tracked by the superproject, when a submodule moves in the
superproject tree, the project can adjust which path gets the
attribute in .gitattributes, just like it can adjust which path has
the submodule in .gitmodules.
Neither of these two additional configuration options solve the problem
of wanting different submodules checked out in different worktrees
because multiple worktrees share .git/config. Only once per-worktree
configurations become a reality can this be solved, but this is a
necessary preparatory step for that future.
Given these multiple ways to check if a submodule is of interest, the
more fine-grained submodule.<name>.active option has the highest order
of precedence followed by the pathspec check against submodule.active.
To ensure backwards compatibility, if neither of these options are set,
git falls back to checking the submodule.<name>.url option to determine
if a submodule is interesting.

e.g. is it overwriting untracked files or are there local
changes that would be overwritten?

In a later patch we'll use connect_work_tree_and_git_dir when the
directory for the gitlink file doesn't exist yet. This patch makes
connect_work_tree_and_git_dir safe to use for both cases of
either the git dir or the working dir missing.
To do so, we need to call safe_create_leading_directories[_const]
on both directories. However this has to happen before we construct
the absolute paths as real_pathdup assumes the directories to
be there already.
So for both the config file in the git dir as well as the .git link
file we need to
a) construct the name
b) call SCLD
c) get the absolute path
d) once a-c is done for both we can consume the absolute path
to compute the relative path to each other and store those
relative paths.
The implementation provided here puts a) and b) for both cases first,
and then performs c and d after.
One of the two users of 'connect_work_tree_and_git_dir' already checked
for the directory being there, so we can loose that check as
connect_work_tree_and_git_dir handles this functionality now.

In 4ac9006f832 (real_path: have callers use real_pathdup and
strbuf_realpath, 2016-12-12), we changed the xstrdup(real_path())
pattern to use real_pathdup() directly.
The problem with this change is that real_path() calls
strbuf_realpath() with die_on_error = 1 while real_pathdup() calls
it with die_on_error = 0. Meaning that in cases where real_path()
causes Git to die() with an error message, real_pathdup() is silent
and returns NULL instead.
The callers, however, are ill-prepared for that change, as they expect
the return value to be non-NULL (and otherwise the function died
with an appropriate error message).
Fix this by extending real_pathdup()'s signature to accept the
die_on_error flag and simply pass it through to strbuf_realpath(),
and then adjust all callers after a careful audit whether they would
handle NULLs well.

Consider having a submodule 'sub' and a nested submodule at 'sub/nested'.
When nested is already absorbed into sub, but sub is not absorbed into
its superproject, then we need to fixup the gitfile and core.worktree
setting for 'nested' when absorbing 'sub', but we do not need to move
its git dir around.
Previously 'nested's gitfile contained "gitdir: ../.git/modules/nested";
it has to be corrected to "gitdir: ../../.git/modules/sub1/modules/nested".
An alternative I considered to do this work lazily, i.e. when resolving
"../.git/modules/nested", we would notice the ".git" being a gitfile
linking to another path. That seemed to be robuster by design, but harder
to get the implementation right. Maybe we have to do that anyway once we
try to have submodules and worktrees working nicely together, but for now
just produce 'correct' (i.e. direct) pointers.

grep: search history of moved submodules
grep: enable recurse-submodules to work on <tree> objects
grep: optionally recurse into submodules
grep: add submodules as a grep source type
submodules: load gitmodules file from commit sha1
submodules: add helper to determine if a submodule is initialized
submodules: add helper to determine if a submodule is populated
real_path: canonicalize directory separators in root parts
real_path: have callers use real_pathdup and strbuf_realpath
real_path: create real_pathdup
real_path: convert real_path_internal to strbuf_realpath
real_path: resolve symlinks by hand

"git push --dry-run --recurse-submodule=on-demand" wasn't
"--dry-run" in the submodules.
* bw/push-dry-run:
push: fix --dry-run to not push submodules
push: --dry-run updates submodules when --recurse-submodules=on-demand

The code in "git push" to compute if any commit being pushed in the
superproject binds a commit in a submodule that hasn't been pushed
out was overly inefficient, making it unusable even for a small
project that does not have any submodule but have a reasonable
number of refs.
* hv/submodule-not-yet-pushed-fix:
submodule_needs_pushing(): explain the behaviour when we cannot answer
batch check whether submodule needs pushing into one call
serialize collection of refs that contain submodule changes
serialize collection of changed submodules

A new submodule helper "git submodule embedgitdirs" to make it
easier to move embedded .git/ directory for submodules in a
superproject to .git/modules/ (and point the latter with the former
that is turned into a "gitdir:" file) has been added.
* sb/submodule-embed-gitdir:
worktree: initialize return value for submodule_uses_worktrees
submodule: add absorb-git-dir function
move connect_work_tree_and_git_dir to dir.h
worktree: check if a submodule uses worktrees
test-lib-functions.sh: teach test_commit -C <dir>
submodule helper: support super prefix
submodule: use absolute path for computing relative path connecting

In C code we have the luxury of having constants for all the important
things that are hard coded. This is the only place in C that hard codes
the git directory environment variable, so fix it.

In different contexts the question "Is it ok to delete a submodule?"
may be answered differently.
In 293ab15eea (submodule: teach rm to remove submodules unless they
contain a git directory, 2012-09-26) a case was made that we can safely
ignore ignored untracked files for removal as we explicitely ask for the
removal of the submodule.
In a later patch we want to remove submodules even when the user doesn't
explicitly ask for it (e.g. checking out a tree-ish in which the submodule
doesn't exist). In that case we want to be more careful when it comes
to deletion of untracked files. As of this patch it is unclear how this
will be implemented exactly, so we'll offer flags in which the caller
can specify how the different untracked files ought to be handled.
As the flags allow the function to not die on an error when spawning
a child process, we need to find an appropriate return code for the
case when the child process could not be started. As in that case we
cannot tell if the submodule is ok to remove, we'd want to return 'false'.
As only 0 is understood as false, rename the function to invert the
meaning, i.e. the return code of 0 signals the removal of the submodule
is fine, and other values can be used to return a more precise answer
what went wrong.
