When an external merge driver dies with a signal, we should not
expect that the result left on the filesystem is in any useful
state. However, because the current code uses the return value from
run_command() and declares any positive value as a sign that the
driver successfully left conflicts in the result, and because the
return value from run_command() for a subprocess that died upon a
signal is positive, we end up treating whatever garbage left on the
filesystem as the result the merge driver wanted to leave us.
run_command() returns larger than 128 (WTERMSIG(status) + 128, to be
exact) when it notices that the subprocess died with a signal, so
detect such a case and return LL_MERGE_ERROR from ll_ext_merge().

The comments in create_default_files() talks about reading config from
the config file in the specified `--templates` directory, which leads to
the question of whether core.bare could be set in such a config file and
thus whether the code is doing the right thing. It turns out, that it
doesn't; it unconditionally ignores core.bare in the config file in any
--templates directory. It is not clear to me that fixing it can be done
within this function; it seems to occur too late:
* create_default_files() is called by init_db()
* init_db() is called by both builtin/{clone.c,init-db.c}
* both callers of init_db() call set_git_work_tree() before init_db()
and in order to actual affect whether a repository is bear, we'd need to
somewhere reset these values, not just the is_bare_repository_cfg
setting.

This commit introduces a new option "--[no-]stripspace" to git notes
append, git notes edit, and git notes add. This option allows users to
control whether the note message need to stripped out.
For the consideration of backward compatibility, let's look at the
behavior about "stripspace" in "git notes" command:
1. "Edit Message" case: using the default editor to edit the note
message.
In "edit" case, the edited message will always be stripped out, the
implementation which can be found in the "prepare_note_data()". In
addition, the "-c" option supports to reuse an existing blob as a
note message, then open the editor to make a further edition on it,
the edited message will be stripped.
This commit doesn't change the default behavior of "edit" case by
using an enum "notes_stripspace", only when "--no-stripspace" option
is specified, the note message will not be stripped out. If you do
not specify the option or you specify "--stripspace", clearly, the
note message will be stripped out.
2. "Assign Message" case: using the "-m"/"-F"/"-C" option to specify the
note message.
In "assign" case, when specify message by "-m" or "-F", the message
will be stripped out by default, but when specify message by "-C",
the message will be copied verbatim, in other word, the message will
not be stripped out. One more thing need to note is "the order of
the options matter", that is, if you specify "-C" before "-m" or
"-F", the reused message by "-C" will be stripped out together,
because everytime concat "-m" or "-F" message, the concated message
will be stripped together. Oppositely, if you specify "-m" or "-F"
before "-C", the reused message by "-C" will not be stripped out.
This commit doesn't change the default behavior of "assign" case by
extending the "stripspace" field in "struct note_msg", so we can
distinguish the different behavior of "-m"/"-F" and "-C" options
when we need to parse and concat the message.

When adding new notes or appending to an existing notes, we will
insert a blank line between the paragraphs, like:
$ git notes add -m foo -m bar
$ git notes show HEAD
foo
bar
The default behavour sometimes is not enough, the user may want
to use a custom delimiter between paragraphs, like when
specifying '-m', '-F', '-C', '-c' options. So this commit
introduce a new '--separator' option for 'git notes add' and
'git notes append', for example when executing:
$ git notes add -m foo -m bar --separator="-"
$ git notes show HEAD
foo
-
bar
a newline is added to the value given to --separator if it
does not end with one already. So when executing:
$ git notes add -m foo -m bar --separator="-"
and
$ export LF="
"
$ git notes add -m foo -m bar --separator="-$LF"
Both the two exections produce the same result.
The reason we use a "strbuf" array to concat but not "string_list", is
that the binary file content may contain '\0' in the middle, this will
cause the corrupt result if using a string to save.

When git-commit sees any "--trailer" options, it passes the
COMMIT_EDITMSG file through git-interpret-trailers. But it does so
without passing --no-divider, which means that interpret-trailers will
look for a "---" divider to signal the end of the commit message.
That behavior doesn't make any sense in this context; we know we have a
complete and solitary commit message, not something we have to further
parse. And as a result, we'll do the wrong thing if the commit message
contains a "---" marker (which otherwise is not syntactically
significant), inserting any new trailers at the wrong spot.
We can fix this by passing --no-divider. This is the exact situation for
which it was added in 1688c9a489 (interpret-trailers: allow suppressing
"---" divider, 2018-08-22). As noted in the message for that commit, it
just adds the mechanism, and further patches were needed to trigger it
from various callers. We did that back then in a few spots, like

While both git-rev-list(1) and git-log(1) support `--stdin`, it only
accepts commits and files. Most notably, it is impossible to pass any of
the pseudo-opts like `--all`, `--glob=` or others via stdin.
This makes it hard to use this function in certain scripted scenarios,
like when one wants to support queries against specific revisions, but
also against reference patterns. While this is theoretically possible by
using arguments, this may run into issues once we hit platform limits
with sufficiently large queries. And because `--stdin` cannot handle
pseudo-opts, the only alternative would be to use a mixture of arguments
and standard input, which is cumbersome.
Implement support for handling pseudo-opts in both commands to support
this usecase better. One notable restriction here is that `--stdin` only
supports "stuck" arguments in the form of `--glob=foo`. This is because
"unstuck" arguments would also require us to read the next line, which
would add quite some complexity to the code. This restriction should be
fine for scripted usage though.

When `diff.ignoreSubmodules = all` is set and submodule commits are
manually staged (e.g. via `git-update-index`), `git-commit` should
record the commit with updated submodules.
`index_differs_from` is called from `prepare_to_commit` with flags set to
`override_submodule_config = 1`. `index_differs_from` then merges the
default diff flags and passed flags.
When `diff.ignoreSubmodules` is set to "all", `flags` ends up having
both `override_submodule_config` and `ignore_submodules` set to 1. This

When opening a MIDX bitmap, we the pack-bitmap machinery eagerly calls
`prepare_midx_pack()` on each of the packs contained in the MIDX. This
is done in order to populate the array of `struct packed_git *`s held by
the MIDX, which we need later on in `load_reverse_index()`, since it
calls `load_pack_revindex()` on each of the MIDX'd packs, and requires
that the caller provide a pointer to a `struct packed_git`.
When opening one of these packs fails, the pack-bitmap code will `die()`
indicating that it can't open one of the packs in the MIDX. This
indicates that the MIDX is somehow broken with respect to the current
state of the repository. When this is the case, we indeed cannot make
use of the MIDX bitmap to speed up reachability traversals.
However, it does not mean that we can't perform reachability traversals
at all. In other failure modes, that same function calls `warning()` and
then returns -1, indicating to its caller (`open_bitmap()`) that we
should either look for a pack bitmap if one is available, or perform
normal object traversal without using bitmaps at all.
There is no reason why this case should cause us to die. If we instead
continued (by jumping to `cleanup` as this patch does) and avoid using
bitmaps altogether, we may again try and query the MIDX, which will also
fail. But when trying to call `fill_midx_entry()` fails, it also returns
a signal of its failure, and prompts the caller to try and locate the
object elsewhere.
In other words, the normal object traversal machinery works fine in the
presence of a corrupt MIDX, so there is no reason that the MIDX bitmap
machinery should abort in that case when we could easily continue.
Note that we *could* in theory try again to load a MIDX bitmap after
calling `reprepare_packed_git()`. Even though the `prepare_packed_git()`
code is careful to avoid adding a pack that we already have,
`prepare_midx_pack()` is not. So if we got part of the way through
calling `prepare_midx_pack()` on a stale MIDX, and then tried again on a
fresh MIDX that contains some of the same packs, we would end up with a
loop through the `->next` pointer.
For now, let's do the simplest thing possible and fallback to the
non-bitmap code when we detect a stale MIDX so that the complete fix as
above can be implemented carefully.

This patch introduces a new multi-valued configuration option,
`gc.recentObjectsHook` as a means to mark certain objects as recent (and
thus exempt from garbage collection), regardless of their age.
When performing a garbage collection operation on a repository with
unreachable objects, Git makes its decision on what to do with those
object(s) based on how recent the objects are or not. Generally speaking,
unreachable-but-recent objects stay in the repository, and older objects
are discarded.
However, we have no convenient way to keep certain precious, unreachable
objects around in the repository, even if they have aged out and would
be pruned. Our options today consist of:
- Point references at the reachability tips of any objects you
consider precious, which may be undesirable or infeasible if there
are many such objects.
- Track them via the reflog, which may be undesirable since the
reflog's lifetime is limited to that of the reference it's tracking
(and callers may want to keep those unreachable objects around for
longer).
- Extend the grace period, which may keep around other objects that
the caller *does* want to discard.
- Manually modify the mtimes of objects you want to keep. If those
objects are already loose, this is easy enough to do (you can just
enumerate and `touch -m` each one).
But if they are packed, you will either end up modifying the mtimes
of *all* objects in that pack, or be forced to write out a loose
copy of that object, both of which may be undesirable. Even worse,
if they are in a cruft pack, that requires modifying its `*.mtimes`
file by hand, since there is no exposed plumbing for this.
- Force the caller to construct the pack of objects they want
to keep themselves, and then mark the pack as kept by adding a
".keep" file. This works, but is burdensome for the caller, and
having extra packs is awkward as you roll forward your cruft pack.
This patch introduces a new option to the above list via the
`gc.recentObjectsHook` configuration, which allows the caller to
specify a program (or set of programs) whose output is treated as a set
of objects to treat as recent, regardless of their true age.
The implementation is straightforward. Git enumerates recent objects via
`add_unseen_recent_objects_to_traversal()`, which enumerates loose and
packed objects, and eventually calls add_recent_object() on any objects
for which `want_recent_object()`'s conditions are met.
This patch modifies the recency condition from simply "is the mtime of
this object more recent than the cutoff?" to "[...] or, is this object
mentioned by at least one `gc.recentObjectsHook`?".
Depending on whether or not we are generating a cruft pack, this allows
the caller to do one of two things:
- If generating a cruft pack, the caller is able to retain additional
objects via the cruft pack, even if they would have otherwise been
pruned due to their age.
- If not generating a cruft pack, the caller is likewise able to
retain additional objects as loose.
A potential alternative here is to introduce a new mode to alter the
contents of the reachable pack instead of the cruft one. One could
imagine a new option to `pack-objects`, say `--extra-reachable-tips`
that does the same thing as above, adding the visited set of objects
along the traversal to the pack.
But this has the unfortunate side-effect of altering the reachability
closure of that pack. If parts of the unreachable object graph mentioned
by one or more of the "extra reachable tips" programs is not closed,
then the resulting pack won't be either. This makes it impossible in the
general case to write out reachability bitmaps for that pack, since
closure is a requirement there.
Instead, keep these unreachable objects in the cruft pack (or set of
unreachable, loose objects) instead, to ensure that we can continue to
have a pack containing just reachable objects, which is always safe to
write a bitmap over.

To partition the set of packs based on which ones are "kept" (either
they have a .keep file, or were otherwise marked via the `--keep-pack`
option) and "non-kept" ones (anything else), `git repack` uses its
`collect_pack_filenames()` function.
Ordinarily, we would rely on a convenience function such as
`get_all_packs()` to enumerate and partition the set of packs. But
`collect_pack_filenames()` uses `readdir()` directly to read the
contents of the "$GIT_DIR/objects/pack" directory, and adds each entry
ending in ".pack" to the appropriate list (either kept, or non-kept as
above).
This is subtly racy, since `collect_pack_filenames()` may see a pack
that is not fully staged (i.e., it is missing its ".idx" file).
Ordinarily, this doesn't cause a problem. But it can cause issues when
generating a cruft pack.
This is because `git repack` feeds (among other things) the list of
existing kept packs down to `git pack-objects --cruft` to indicate that
any kept packs will not be removed from the repository (so that the
cruft pack machinery can avoid packing objects that appear in those
packs as cruft).
But `read_cruft_objects()` lists packfiles by calling `get_all_packs()`.
So if a ".pack" file exists (necessary to get that pack to appear to
`collect_pack_filenames()`), but doesn't have a corresponding ".idx"
file (necessary to get that pack to appear via `get_all_packs()`), we'll
complain with:
fatal: could not find pack '.tmp-5841-pack-a6b0150558609c323c496ced21de6f4b66589260.pack'
Fix the above by teaching `collect_pack_filenames()` to only collect
packs with their corresponding `*.idx` files in place, indicating that
those packs have been fully staged.
There are a couple of things worth noting:
- Since each entry in the `extra_keep` list (which contains the
`--keep-pack` names) has a `*.pack` suffix, we'll have to swap the
suffix from ".pack" to ".idx", and compare that instead.
- Since we use the the `fname_kept_list` to figure out which packs to
delete (with `git repack -d`), we would have previously deleted a
`*.pack` with no index (since the existince of a ".pack" file is
necessary and sufficient to include that pack in the list of
existing non-kept packs).
Now we will leave it alone (since that pack won't appear in the
list). This is far more correct behavior, since we don't want
to race with a pack being staged. Deleting a partially staged pack
is unlikely, however, since the window of time between staging a
pack and moving its .idx file into place is miniscule.
Note that this window does *not* include the time it takes to
receive and index the pack, since the incoming data goes into
"$GIT_DIR/objects/tmp_pack_XXXXXX", which does not end in ".pack"
and is thus ignored by collect_pack_filenames().
In the future, this function should probably be rewritten as a callback
to `for_each_file_in_pack_dir()`, but this is the simplest change we
could do in the short-term.

The GPGSSH_VERIFYTIME prequeq makes use of "${GNUPGHOME}" but does not
create it. Require GPGSSH which creates the "${GNUPGHOME}" directory.
Additionally, it makes sense to require GPGSSH in GPGSSH_VERIFYTIME
because the latter builds on the former. If we can't use GPGSSH,
there's little point in checking whether GPGSSH_VERIFYTIME is usable.
