The point of having a whitelist of command-line config
options to pass to submodules was two-fold:
1. It prevented obvious nonsense like using core.worktree
for multiple repos.
2. It could prevent surprise when the user did not mean
for the options to leak to the submodules (e.g.,
http.sslverify=false).
For case 1, the answer is mostly "if it hurts, don't do
that". For case 2, we can note that any such example has a
matching inverted surprise (e.g., a user who meant
http.sslverify=true to apply everywhere, but it didn't).
So this whitelist is probably not giving us any benefit, and
is already creating a hassle as people propose things to put
on it. Let's just drop it entirely.
Note that we still need to keep a special code path for
"prepare the submodule environment", because we still have
to take care to pass through $GIT_CONFIG_PARAMETERS (and
block the rest of the repo-specific environment variables).
We can do this easily from within the submodule shell
script, which lets us drop the submodule--helper option
entirely (and it's OK to do so because as a "--" program, it
is entirely a private implementation detail).

"git describe --contains" often made a hard-to-justify choice of
tag to give name to a given commit, because it tried to come up
with a name with smallest number of hops from a tag, causing an old
commit whose close descendant that is recently tagged were not
described with respect to an old tag but with a newer tag. It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge. The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit
in terms of the (chronologically) oldest tag that contains the
commit."

ba3c69a9 (commit: teach --gpg-sign option, 2011-10-05) introduced a
"signed commit" by teaching the --[no]-gpg-sign option and the
commit.gpgsign configuration variable to various commands that
create commits.
Teaching these to "git commit" and "git merge", both of which are
end-user facing Porcelain commands, was perfectly fine. Allowing
the plumbing "git commit-tree" to suddenly change the behaviour to
surprise the scripts by paying attention to commit.gpgsign was not.
Among the in-tree scripts, filter-branch, quiltimport, rebase and
stash are the commands that run "commit-tree". If any of these
wants to allow users to always sign every single commit, they should
offer their own configuration (e.g. "filterBranch.gpgsign") with an
option to disable signing (e.g. "git filter-branch --no-gpgsign").
Ignoring commit.gpgsign option _obviously_ breaks the backward
compatibility, but it is easy to follow the standard pattern in
scripts to honor whatever configuration variable they choose to
follow. E.g.
case $(git config --bool commit.gpgsign) in
true) sign=-S ;;
*) sign= ;;
esac &&
git commit-tree $sign ...whatever other args...
Do so to make sure that "git rebase" keeps paying attention to the
configuration variable, which unfortunately is a documented mistake.

This should not regress any scripts that try to parse the

We want to init submodules from the helper for `submodule update`

the patch series applies to. Teach git format-patch a '--base' option
to record the base tree info and append it at the end of the first
message (either the cover letter or the first patch in the series).
The base tree info consists of the "base commit", which is a well-known
commit that is part of the stable part of the project history everybody
else works off of, and zero or more "prerequisite patches", which are
well-known patches in flight that is not yet part of the "base commit"
that need to be applied on top of "base commit" in topological order
before the patches can be applied.
The "base commit" is shown as "base-commit: " followed by the 40-hex of
the commit object name. A "prerequisite patch" is shown as
"prerequisite-patch-id: " followed by the 40-hex "patch id", which can
be obtained by passing the patch through the "git patch-id --stable"
command.
Imagine that on top of the public commit P, you applied well-known
patches X, Y and Z from somebody else, and then built your three-patch
series A, B, C, the history would be like:
---P---X---Y---Z---A---B---C
With "git format-patch --base=P -3 C" (or variants thereof, e.g. with
"--cover-letter" of using "Z..C" instead of "-3 C" to specify the
range), the base tree information block is shown at the end of the
first message the command outputs (either the first patch, or the
cover letter), like this:
base-commit: P

When creating a shallow clone of a repository with submodules, the depth
argument does not influence the submodules, i.e. the submodules are done
as non-shallow clones. It is unclear what the best default is for the
depth of submodules of a shallow clone, so we need to have the possibility
to do all kinds of combinations:
* shallow super project with shallow submodules
e.g. build bots starting always from scratch. They want to transmit
the least amount of network data as well as using the least amount
of space on their hard drive.
* shallow super project with unshallow submodules
e.g. The superproject is just there to track a collection of repositories
and it is not important to have the relationship between the repositories
intact. However the history of the individual submodules matter.
* unshallow super project with shallow submodules
e.g. The superproject is the actual project and the submodule is a
library which is rarely touched.
The new switch to select submodules to be shallow or unshallow supports
all of these three cases.
It is easy to transition from the first to the second case by just
unshallowing the submodules (`git submodule foreach git fetch
--unshallow`), but it is not possible to transition from the second to the
first case (as we would have already transmitted the non shallow over
the network). That is why we want to make the first case the default in
case of a shallow super project. This leads to the inconvenience in the
second case with the shallow super project and unshallow submodules,
as you need to pass `--no-shallow-submodules`.

This function find_shared_symref() is used in a couple places:
1) in builtin/branch.c: it's used to detect if a branch is checked out
elsewhere and refuse to delete the branch.
2) in builtin/notes.c: it's used to detect if a note is being merged in
another worktree
3) in branch.c, the function die_if_checked_out() is actually used by
"git checkout" and "git worktree add" to see if a branch is already
checked out elsewhere and refuse the operation.
In cases 1 and 3, if a rebase is ongoing, "HEAD" will be in detached
mode, find_shared_symref() fails to detect it and declares "no branch is
checked out here", which is not really what we want.
This patch tightens the test. If the given symref is "HEAD", we try to
detect if rebase is ongoing. If so return the branch being rebased. This
makes checkout and branch delete operations safer because you can't
checkout a branch being rebased in another place, or delete it.
Special case for checkout. If the current branch is being rebased,
git-rebase.sh may use "git checkout" to abort and return back to the
original branch. The updated test in find_shared_symref() will prevent
that and "git rebase --abort" will fail as a result.
find_shared_symref() and die_if_checked_out() have to learn a new
option ignore_current_worktree to loosen the test a bit.

By having the `submodule init` functionality in C, we can reference it
easier from other parts in the code in later patches. The code is split
up to have one function to initialize one submodule and a calling function
that takes care of the rest, such as argument handling and translating the
arguments to the paths of the submodules.
This is the first submodule subcommand that is fully converted to C
except for the usage string, so this is actually removing a call to
the `submodule--helper list` function, which is supposed to be used in
this transition. Instead we'll make a direct call to `module_list_compute`.
An explanation why we need to edit the prefixes in cmd_update in
git-submodule.sh in this patch:
By having no processing in the shell part, we need to convey the notion
of wt_prefix and prefix to the C parts, which former patches punted on
and did the processing of displaying path in the shell.
`wt_prefix` used to hold the path from the repository root to the current
directory, e.g. wt_prefix would be t/ if the user invoked the
`git submodule` command in ~/repo/t and ~repo is the GIT_DIR.
`prefix` used to hold the relative path from the repository root to the
operation, e.g. if you have recursive submodules, the shell script would
modify the `prefix` in each recursive step by adding the submodule path.
We will pass `wt_prefix` into the C helper via `git -C <dir>` as that
will setup git in the directory the user actually called git-submodule.sh
from. The `prefix` will be passed in via the `--prefix` option.
Having `prefix` and `wt_prefix` relative to the GIT_DIR of the
calling superproject is unfortunate with this patch as the C code doesn't
know about a possible recursion from a superproject via `submodule update
--init --recursive`.
To fix this, we change the meaning of `wt_prefix` to point to the current
project instead of the superproject and `prefix` to include any relative
paths issues in the superproject. That way `prefix` will become the leading
part for displaying paths and `wt_prefix` will be empty in recursive
calls for now.
The new notion of `wt_prefix` and `prefix` still allows us to reconstruct
the calling directory in the superproject by just traveling reverse of
`prefix`.

Later on we want to automatically call `git submodule init` from

already, we'd need the init functionality in C, too. The
`resolve_relative_url` function is a large part of that init
functionality, so start by porting this function to C.
To create the tests in t0060, the function `resolve_relative_url`
was temporarily enhanced to write all inputs and output to disk
when running the test suite. The added tests in this patch are

If read_tree_trivial() succeeds and produces a tree that is already
in the object store, then the index is not written to disk, leaving
it out-of-sync with both HEAD and the working tree.
In order to write the index back out to disk after a merge,
write_index_locked() needs to be called. For most merge strategies, this
is done from try_merge_strategy(). For fast forward updates, this is
done from checkout_fast_forward(). When trivial merges work, the call to
write_index_locked() is buried a little deeper:
merge_trivial()
-> write_tree_trivial()
-> write_cache_as_tree()
-> write_index_as_tree()
-> write_locked_index()
However, it is only called when !cache_tree_fully_valid(), which is how
this bug is triggered. But that also shows why this bug doesn't affect
any other merge strategies or cases.
Add a direct call to write_index_locked() from merge_trivial() to fix
this issue. Since the indirect call to write_locked_index() was
conditional on cache_tree_fully_valid(), it won't be written twice.

"git merge" used to allow merging two branches that have no common

When f9568530 (builtin-commit: resurrect behavior for multiple -m
options, 2007-11-11) converted a "char *message" to "struct strbuf
message" to hold the messages given with the "-m" option, it
incorrectly changed the checks "did we get a message with the -m
option?" to "is message.len 0?". Later, we noticed one breakage
from this change and corrected it with 25206778 (commit: don't start
editor if empty message is given with -m, 2013-05-25).
However, "we got a message with -m, even though an empty one, so we
shouldn't be launching an editor" was not the only breakage.
* "git commit --amend -m '' --allow-empty", even though it looks
strange, is a valid request to amend the commit to have no
message at all. Due to the misdetection of the presence of -m on
the command line, we ended up keeping the log messsage from the
original commit.
* "git commit -m "$msg" -F file" should be rejected whether $msg is
an empty string or not, but due to the same bug, was not rejected
when $msg is empty.
* "git -c template=file -m "$msg"" should ignore the template even
when $msg is empty, but it didn't and instead used the contents
from the template file.
Correct these by checking have_option_m, which the earlier 25206778
introduced to fix the same bug.

The verify_signed_buffer() function may trigger a SIGPIPE when the
GPG child process terminates early (due to a bad keyid, for example)
and Git tries to write to it afterwards. Previously, ignoring
SIGPIPE was done in builtin/verify-tag.c to avoid this issue.
However, any other caller who wants to call verify_signed_buffer()
would have to do the same.
Use sigchain_push(SIGPIPE, SIG_IGN) in verify_signed_buffer(),
pretty much like in sign_buffer(), so that any caller is not
required to perform this task.
This will avoid possible mistakes by further developers using

Commit aedcb7d (branch.c: use 'ref-filter' APIs, 2015-09-23)
adjusted the symref-printing code to look like this:
if (item->symref) {
skip_prefix(item->symref, "refs/remotes/", &desc);
strbuf_addf(&out, " -> %s", desc);
}
This has three bugs in it:
1. It always skips past "refs/remotes/", instead of
skipping past the prefix associated with the branch we
are showing (so commonly we see "refs/remotes/" for the
refs/remotes/origin/HEAD symref, but the previous code
would skip "refs/heads/" when showing a symref it found
in refs/heads/.
2. If skip_prefix() does not match, it leaves "desc"
untouched, and we show whatever happened to be in it
(which is the refname from a call to skip_prefix()
earlier in the function).
3. If we do match with skip_prefix(), we stomp on the
"desc" variable, which is later passed to
add_verbose_info(). We probably want to retain the
original refname there (though it likely doesn't matter
in practice, since after all, one points to the other).
The fix to match the original code is fairly easy: record
the prefix to strip based on item->kind, and use it here.
However, since we already have a local variable named "prefix",
let's give the two prefixes verbose names so we don't
confuse them.

memory model is that the caller shouldn't rely too much on the

Also parse_binary_hunk() sets "status" to -1 in case of error and

When using git send-pack with --all option
and a target repository specification ([<host>:]<directory>),
usage message is being displayed instead of performing
the actual transmission.
The reason for this issue is that destination and refspecs are being set
in the same conditional and are populated from argv. When a target
repository is passed, refspecs is being populated as well with its value.
This makes the check for refspecs not being NULL to always return true,
which, in conjunction with the check for --all or --mirror options,
is always true as well and returns usage message instead of proceeding.
This ensures that send-pack will stop execution only when --all
or --mirror switch is used in conjunction with any refspecs passed.

submodule: fix regression for deinit without submodules
While it makes sense to allow merging unrelated histories of two
projects that started independently into one, in the way "gitk" was
merged to "git" itself aka "the coolest merge ever", such a merge is
still an unusual event. Worse, if somebody creates an independent
history by starting from a tarball of an established project and
sends a pull request to the original project, "git merge" however
happily creates such a merge without any sign of something unusual
is happening.
Teach "git merge" to refuse to create such a merge by default,
unless the user passes a new "--allow-unrelated-histories" option to
tell it that the user is aware that two unrelated projects are
merged.
Because such a "two project merge" is a rare event, a configuration
option to always allow such a merge is not added.
We could add the same option to "git pull" and have it passed
through to underlying "git merge". I do not have a fundamental
opposition against such a feature, but this commit does not do so
and instead leaves it as low-hanging fruit for others, because such
a "two project merge" would be done after fetching the other project
into some location in the working tree of an existing project and
making sure how well they fit together, it is sufficient to allow a
local merge without such an option pass-through from "git pull" to
"git merge". Many tests that are updated by this patch does the
pass-through manually by turning:
git pull something
into its equivalent:
git fetch something &&
git merge --allow-unrelated-histories FETCH_HEAD
If somebody is inclined to add such an option, updated tests in this
change need to be adjusted back to:
git pull --allow-unrelated-histories something

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.

The `tag.forcesignannotated` configuration variable makes "git tag"
that would implicitly create an annotated tag to instead create a
signed tag. For example
$ git tag -m "This is a message" tag-with-message
$ git tag -F message-file tag-with-message
would create a signed tag if the configuration variable is in
effect. To override this from the command line, the user can
explicitly ask for an annotated tag, like so:
$ git tag -a -m "This is a message" tag-with-message
$ git tag -a -F message-file tag-with-message
Creation of a light-weight tag, i.e.
$ git tag lightweight
is not affected.

These two functions keep a copy of filename it was given, let
gitdiff_verify_name() to rewrite it to a new filename and then free
the original if they receive a newly minted filename.
However
(1) when the original name is NULL, gitdiff_verify_name() returns
either NULL or a newly minted value. Either case, we do not
have to worry about calling free() on the original NULL.
(2) when the original name is not NULL, gitdiff_verify_name()
either returns that as-is, or calls die() when it finds
inconsistency in the patch. When the function returns, we know
that "if ()" statement always is false.

If rebase.autoStash configuration variable is set, there is no way to
override it for "git pull --rebase" from the command line.
Teach "git pull --rebase" the --[no-]autostash command line flag which
overrides the current value of rebase.autoStash, if set. As "git rebase"
understands the --[no-]autostash option, it's just a matter of passing
the option to underlying "git rebase" when "git pull --rebase" is called.

When we find a blob at "a/b/c", we currently pass this to
our show_object_fn callbacks as two components: "a/b/" and
"c". Callbacks which want the full value then call
path_name(), which concatenates the two. But this is an
inefficient interface; the path is a strbuf, and we could
simply append "c" to it temporarily, then roll back the
length, without creating a new copy.
So we could improve this by teaching the callsites of
path_name() this trick (and there are only 3). But we can
also notice that no callback actually cares about the
broken-down representation, and simply pass each callback
the full path "a/b/c" as a string. The callback code becomes
even simpler, then, as we do not have to worry about freeing
an allocated buffer, nor rolling back our modification to
the strbuf.
This is theoretically less efficient, as some callbacks
would not bother to format the final path component. But in
practice this is not measurable. Since we use the same
strbuf over and over, our work to grow it is amortized, and
we really only pay to memcpy a few bytes.

In the previous commit, we left name_path as a thin wrapper
around a strbuf. This patch drops it entirely. As a result,
every show_object_fn callback needs to be adjusted. However,
none of their code needs to be changed at all, because the
only use was to pass it to path_name(), which now handles
the bare strbuf.

If we are running "git grep --no-index" outside of a git
repository, we behave roughly like "grep -r", examining all
files in the current directory and its subdirectories.
However, because we use fill_directory() to do the
recursion, it will skip over any directories which look like
sub-repositories.
For a normal git operation (like "git grep" in a repository)
this makes sense; we do not want to cross the boundary out
of our current repository into a submodule. But for
"--no-index" without a repository, we should look at all
files, including embedded repositories.
There is one exception, though: we probably should _not_
descend into ".git" directories. Doing so is inefficient and
unlikely to turn up useful hits.
This patch drops our use of dir.c's gitlink-detection, but
we do still avoid ".git". That makes us more like tools such
as "ack" or "ag", which also know to avoid cruft in .git.
As a bonus, this also drops our usage of the ref code
when we are outside of a repository, making the transition
to pluggable ref backends cleaner.

When setup_git_directory() is called, we set a flag in
startup_info to indicate we have a repository. But there are
a few other mechanisms by which we might set up a repo:
1. When creating a new repository via init_db(), we
transition from no-repo to being in a repo. We should
tweak this flag at that moment.
2. In enter_repo(), a stricter form of
setup_git_directory() used by server-side programs, we
check the repository format config. After doing so, we
know we're in a repository, and can set the flag.
With these changes, library code can now reliably tell
whether we are in a repository and act accordingly. We'll
leave the "prefix" field as NULL, which is what happens when
setup_git_directory() finds there is no prefix.

As we create the .keep file with O_CREAT|O_EXCL, and we do so after

because we deliberately ignored EEXIST when creating .keep file

Due to the way that the git-submodule code works, it clears all local
git environment variables before entering submodules. This is normally
a good thing since we want to clear settings such as GIT_WORKTREE and
other variables which would affect the operation of submodule commands.
However, GIT_CONFIG_PARAMETERS is special, and we actually do want to
preserve these settings. However, we do not want to preserve all
configuration as many things should be left specific to the parent
project.
Add a git submodule--helper function, sanitize-config, which shall be
used to sanitize GIT_CONFIG_PARAMETERS, removing all key/value pairs
except a small subset that are known to be safe and necessary.
Replace all the calls to clear_local_git_env with a wrapped function
that filters GIT_CONFIG_PARAMETERS using the new helper and then
restores it to the filtered subset after clearing the rest of the
environment.
