As there are plans to implement other ref storage systems,
let's use a way to remove remote refs that does not depend
on refs being files.
This makes it clear to readers that this test does not
depend on which ref backend is used.

upload-pack: reject shallow requests that would return nothing
Shallow clones with --shallow-since or --shalow-exclude work by
running rev-list to get all reachable commits, then draw a boundary
between reachable and unreachable and send "shallow" requests based on
that.
The code does miss one corner case: if rev-list returns nothing, we'll
have no border and we'll send no shallow requests back to the client
(i.e. no history cuts). This essentially means a full clone (or a full
branch if the client requests just one branch). One example is the
oldest commit is older than what is specified by --shallow-since.
To avoid this, if rev-list returns nothing, we abort the clone/fetch.
The user could adjust their request (e.g. --shallow-since further back
in the past) and retry.
Another possible option for this case is to fall back to a default
depth (like depth 1). But I don't like too much magic that way because
we may return something unexpected to the user. If they request
"history since 2008" and we return a single depth at 2000, that might
break stuff for them. It is better to tell them that something is
wrong and let them take the best course of action.
Note that we need to die() in get_shallow_commits_by_rev_list()
instead of just checking for empty result from its caller
deepen_by_rev_list() and handling the error there. The reason is,
empty result could be a valid case: if you have commits in year 2013
and you request --shallow-since=year.2000 then you should get a full
clone (i.e. empty result).

fetch: do not pass ref-prefixes for fetch by exact SHA1
When v2.18.0-rc0~10^2~1 (refspec: consolidate ref-prefix generation
logic, 2018-05-16) factored out the ref-prefix generation code for
reuse, it left out the 'if (!item->exact_sha1)' test in the original
ref-prefix generation code. As a result, fetches by SHA-1 generate
ref-prefixes as though the SHA-1 being fetched were an abbreviated ref
name:
If there is another ref name on the command line or the object being
fetched is already available locally, then that's mostly harmless.
But otherwise, we error out with
fatal: no matching remote head
since the server did not send any refs we are interested in. Filter
out the exact_sha1 refspecs to avoid this.
This patch adds a test to check this behavior that notices another
behavior difference between protocol v0 and v2 in the process. Add a
NEEDSWORK comment to clear it up.

index-pack: handle --strict checks of non-repo packs
Commit 73c3f0f704 (index-pack: check .gitmodules files with
--strict, 2018-05-04) added a call to add_packed_git(), with
the intent that the newly-indexed objects would be available
to the process when we run fsck_finish(). But that's not
what add_packed_git() does. It only allocates the struct,
and you must install_packed_git() on the result. So that
call was effectively doing nothing (except leaking a
struct).
But wait, we passed all of the tests! Does that mean we
don't need the call at all?
For normal cases, no. When we run "index-pack --stdin"
inside a repository, we write the new pack into the object
directory. If fsck_finish() needs to access one of the new
objects, then our initial lookup will fail to find it, but
we'll follow up by running reprepare_packed_git() and
looking again. That logic was meant to handle somebody else
repacking simultaneously, but it ends up working for us
here.
But there is a case that does need this, that we were not
testing. You can run "git index-pack foo.pack" on any file,
even when it is not inside the object directory. Or you may
not even be in a repository at all! This case fails without
doing the proper install_packed_git() call.
We can make this work by adding the install call.
Note that we should be prepared to handle add_packed_git()
failing. We can just silently ignore this case, though. If
fsck_finish() later needs the objects and they're not
available, it will complain itself. And if it doesn't
(because we were able to resolve the whole fsck in the first
pass), then it actually isn't an interesting error at all.

prepare_commit_graft: treat non-repository as a noop
The parse_commit_buffer() function consults lookup_commit_graft()
to see if we need to rewrite parents. The latter will look
at $GIT_DIR/info/grafts. If you're outside of a repository,
then this will trigger a BUG() as of b1ef400eec (setup_git_env:
avoid blind fall-back to ".git", 2016-10-20).
It's probably uncommon to actually parse a commit outside of
a repository, but you can see it in action with:
cd /not/a/git/repo
git index-pack --strict /some/file.pack
This works fine without --strict, but the fsck checks will
try to parse any commits, triggering the BUG(). We can fix
that by teaching the graft code to behave as if there are no
grafts when we aren't in a repository.
Arguably index-pack (and fsck) are wrong to consider grafts
at all. So another solution is to disable grafts entirely
for those commands. But given that the graft feature is
deprecated anyway, it's not worth even thinking through the
ramifications that might have.
There is one other corner case I considered here. What
should:
cd /not/a/git/repo
export GIT_GRAFT_FILE=/file/with/grafts
git index-pack --strict /some/file.pack
do? We don't have a repository, but the user has pointed us
directly at a graft file, which we could respect. I believe
this case did work that way prior to b1ef400eec. However,
fixing it now would be pretty invasive. Back then we would
just call into setup_git_env() even without a repository.
But these days it actually takes a git_dir argument. So
there would be a fair bit of refactoring of the setup code
involved.
Given the obscurity of this case, plus the fact that grafts
are deprecated and probably shouldn't work under index-pack
anyway, it's not worth pursuing further. This patch at least
un-breaks the common case where you're _not_ using grafts,
but we BUG() anyway trying to even find that out.

rebase: use the new git-rebase--preserve-merges.sh
Create a new type of rebase, "preserve-merges", used when rebase is
called with -p.
Before that, the type for preserve-merges was "interactive", and some
places of this script compared $type to "interactive". Instead, the code
now checks if $interactive_rebase is empty or not, as it is set to
"explicit" when calling an interactive rebase (and, possibly, one of its
submodes), and "implied" when calling one of its
submodes (eg. preserve-merges) *without* interactive rebase.
It also detects the presence of the directory "$merge_dir"/rewritten
left by the preserve-merges script when calling rebase --continue,
--skip, etc., and, if it exists, sets the rebase mode to
preserve-merges. In this case, interactive_rebase is set to "explicit",
as "implied" would break some tests.

equivalent to that of a hex object ID. Use the_hash_algo so this code

but it's harder to search if you want to focus on the variable name,
for example.
This is not the best way to collect the available config since it's
not precise. Ideally we should have a centralized list of config in C
code (pretty much like 'struct option'), but that's a lot more work.
This will do for now.

fsck: factor out msg_id_info[] lazy initialization code
This array will be used by some other function than parse_msg_id() in
the following commit. Factor out this prep code so it could be called
from that one.

Add and use generic name->id mapping code for color slot parsing
Instead of hard coding the name-to-id mapping in C code, keep it in an
array and use a common function to do the parsing. This reduces code
and also allows us to list all possible color slots later.
This starts using C99 designated initializers more for convenience
(the first designated initializers have been introduced in builtin/clean.c
for some time without complaints)

Most --no- options do have some use, even if rarely to negate some
option that's specified in an alias.
These options --no-ours and --no-theirs however have no clear
semantics. If I specify "--ours --no-theirs", the second will reset
writeout stage and is equivalent of "--no-ours --no-theirs" which is
not that easy to see. Drop them. You can either switch from --ours to
--theirs and back but you can never negate them.
