We try to delete the non-existing tag "anothertag", but for the
verifications, we check that the tag "myhead" doesn't exist. "myhead"
isn't used in this test except for this checking. Comparing to the test
two tests earlier, it looks like a copy-paste mistake.
Perhaps it's overkill to check that `git tag -d` didn't decide to
*create* a tag. But since we're trying to be this careful, let's
actually check the correct tag. While we're doing this, let's use a more
descriptive tag name instead -- "nonexistingtag" should be obvious.

In 'do_apply_stash()' we refresh the index in the end. Since
34933d0eff ("stash: make sure to write refreshed cache", 2019-09-11),
we also write that refreshed index when --quiet is given to 'git stash
apply'.
However if '--index' is not given to 'git stash apply', we also
discard the index in the else clause just before. We need to do so
because we use an external 'git update-index --add --stdin', which
leads to an out of date in-core index.
Later we call 'refresh_and_write_cache', which now leads to writing
the discarded index, which means we essentially write an empty index
file. This is obviously not correct, or the behaviour the user
wanted. We should not modify the users index without being asked to
do so.
Make sure to re-read the index after discarding the current in-core
index, to avoid dealing with outdated information. Instead we could
also drop the 'discard_cache()' + 'read_cache()', however that would
make it easy to fall into the same trap as 34933d0eff did, so it's
better to avoid that.
We can also drop the 'refresh_and_write_cache' completely in the quiet
case. Previously in legacy stash we relied on 'git status' to refresh
the index after calling 'git read-tree' when '--index' was passed to
'git apply'. However the 'reset_tree()' call that replaced 'git
read-tree' always passes options that are equivalent to '-m', making
the refresh of the index unnecessary.

When we're pushing a pack and our local pack-objects fails, we enter an
error code path that does a few things:
1. Set the status of every ref to REF_STATUS_NONE
2. Call receive_unpack_status() to try to get an error report from
the other side
3. Return an error to the caller
If pack-objects failed because the connection to the server dropped,
there's not much more we can do than report the hangup. And indeed, step
2 will try to read a packet from the other side, which will die() in the
packet-reading code with "the remote end hung up unexpectedly".
But if the connection _didn't_ die, then the most common issue is that
the remote index-pack or unpack-objects complained about our pack (we
could also have a local pack-objects error, but this ends up being the
same; we'd send an incomplete pack and the remote side would complain).
In that case we do report the error from the other side (because of step
2), but we fail to say anything further about the refs. The issue is
two-fold:
- in step 1, the "NONE" status is not "we saw an error, so we have no
status". It generally means "this ref did not match our refspecs, so
we didn't try to push it". So when we print out the push status
table, we won't mention any refs at all!
But even if we had a status enum for "pack-objects error", we
wouldn't want to blindly set it for every ref. For example, in a
non-atomic push we might have rejected some refs already on the
client side (e.g., REF_STATUS_REJECT_NODELETE) and we'd want to
report that.
- in step 2, we read just the unpack status. But receive-pack will
also tell us about each ref (usually that it rejected them because
of the unpacker error).
So a much better strategy is to leave the ref status fields as they are
(usually EXPECTING_REPORT) and then actually receive (and print) the
full per-ref status.
This case is actually covered in the test suite, as t5504.8, which
writes a pack that will be rejected by the remote unpack-objects. But
it's racy. Because our pack is small, most of the time pack-objects
manages to write the whole thing before the remote rejects it, and so it
returns success and we print out the errors from the remote. But very
occasionally (or when run under --stress) it goes slow enough to see a
failure in writing, and git-push reports nothing for the refs.
With this patch, the test should behave consistently.
There shouldn't be any downside to this approach. If we really did see
the connection drop, we'd already die in receive_unpack_status(), and
we'll continue to do so. If the connection drops _after_ we get the
unpack status but before we see any ref status, we'll still print the
remote unpacker error, but will now say "remote end hung up" instead of
returning the error up the call-stack. But as discussed, we weren't
showing anything more useful than that with the current code. And
anyway, that case is quite unlikely (the connection dropping at that
point would have to be unrelated to the pack-objects error, because of
the ordering of events).
In the future we might want to handle packet-read errors ourself instead
of dying, which would print a full ref status table even for hangups.
But in the meantime, this patch should be a strict improvement.

Commit 6462d5eb9a ("fetch: remove fetch_if_missing=0", 2019-11-08)
strove to remove the need for fetch_if_missing=0 from the fetching
mechanism, so it is plausible to attempt removing fetch_if_missing=0
from the lazy-fetching mechanism in promisor-remote as well.
But doing so reveals a bug - when the server does not send an object
pointed to by a tag object, an infinite loop occurs: Git attempts to
fetch the missing object, which causes a deferencing of all refs (for
negotiation), which causes a lazy fetch of that missing object, and so
on. This bug is because of unnecessary use of the fetch negotiator
during lazy fetching - it is not used after initialization, but it is
still initialized (which causes the dereferencing of all refs).
Thus, when the negotiator is not used during fetching, refrain from
initializing it. Then, remove fetch_if_missing from promisor-remote.

Commit 6462d5eb9a ("fetch: remove fetch_if_missing=0", 2019-11-08)
strove to remove the need for fetch_if_missing=0 from the fetching
mechanism, so it is plausible to attempt removing fetch_if_missing=0
from clone as well. But doing so reveals a bug - when the server does
not send an object directly pointed to by a ref, this should be an
error, not a trigger for a lazy fetch. (This case in the fetching
mechanism was covered by a test using "git clone", not "git fetch",
which is why the aforementioned commit didn't uncover the bug.)
The bug can be fixed by suppressing lazy-fetching during the
connectivity check. Fix this bug, and remove fetch_if_missing from
clone.

parse_options_dup() counts the number of elements in the given array
without the end marker, allocates enough memory to hold all of them plus
an end marker, then copies them and terminates the new array. The
counting part is done by advancing a pointer through the array, and the
original pointer is reconstructed using pointer subtraction before the
copy operation.
The function is also prepared to handle a NULL pointer passed to it.
None of its callers do that currently, but this feature was used by
46e91b663b ("checkout: split part of it to new command 'restore'",
2019-04-25); it seems worth keeping.
It ends up doing arithmetic on that NULL pointer, though, which is
undefined in standard C, when it tries to calculate "NULL - 0". Better
avoid doing that by remembering the originally given pointer value.
There is another issue, though. memcpy(3) does not support NULL
pointers, even for empty arrays. Use COPY_ARRAY instead, which does
support such empty arrays. Its call is also shorter and safer by
inferring the element type automatically.
Coccinelle and contrib/coccinelle/array.cocci did not propose to use
COPY_ARRAY because of the pointer subtraction and because the source is
const -- the semantic patch cautiously only considers pointers and array
references of the same type.

Use the macro COPY_ARRAY to copy array elements. The result is shorter
and safer, as it infers the element type automatically and does a (very)
basic type compatibility check for its first two arguments.
Coccinelle and contrib/coccinelle/array.cocci did not generate this
conversion due to the offset of 1 at both source and destination and
because the source is a const pointer; the semantic patch cautiously
handles only pure pointers and array references of the same type.

The 'git commit-graph read' subcommand is used in test scripts to check
that the commit-graph contents match the expected data. Mostly, this
helps check the header information and the list of chunks. Users do not
need this information, so move the functionality to a test helper.
