"git checkout -m <other>" was about carrying the differences
between HEAD and the working-tree files forward while checking out
another branch, and ignored the differences between HEAD and the

When we have a multi-pack-index that covers many packfiles, we try to
avoid opening the .idx for those packfiles. To do that we feed the pack
name to midx_contains_pack(). But that function wants to see only the
basename, which we compute using strrchr() to find the final slash. But
that leaves an extra "/" at the start of our string.
We can fix this by incrementing the pointer. That also raises the
question of what to do when the name does not have a '/' at all. This
should generally not happen (we always find files in "pack/"), but it
doesn't hurt to be defensive here.
Let's wrap all of that up in a helper function and make it publicly
available, since a later patch will need to use it, too.
The tests don't notice because there's nothing about opening those .idx
files that would cause us to give incorrect output. It's just a little
slower. The new test checks this case by corrupting the covered .idx,
and then making sure we don't complain about it.
We also have to tweak t5570, which intentionally corrupts a .idx file
and expects us to notice it. When run with GIT_TEST_MULTI_PACK_INDEX,
this will fail since we now will (correctly) not bother opening the .idx
at all. We can fix that by unconditionally dropping any midx that's
there, which ensures we'll have to read the .idx.

There's no such argument as "--unsorted"; it's spelled "--unordered".
But our test failed to notice that cat-file didn't run at all because:
1. It lost the exit code of git on the left-hand side of a pipe.
2. It was comparing two runs of the broken invocation with and without
a particular config variable (and indeed, both cases produced no
output!).
Let's fix the option, but also tweak the helper function to check the
exit code.

Git's command-line parsers support uniquely abbreviated options, e.g.
`git init --ba` would automatically expand `--ba` to `--bare`.
This is a very convenient feature in every day life for Git users, in
particular when tab completion is not available.
However, it is not a good idea to rely on that in Git's test suite, as
something that is a unique abbreviation of a command line option today
might no longer be a unique abbreviation tomorrow.
For example, if a future contribution added a new mode
`git init --babyproofing` and a previously-introduced test case used the
fact that `git init --ba` expanded to `git init --bare`, that future
contribution would now have to touch seemingly unrelated tests just to
keep the test suite from failing.
So let's disallow abbreviated options in the test suite by default.
Note: for ease of implementation, this patch really only touches the
`parse-options` machinery: more and more hand-rolled option parsers are
converted to use that internal API, and more and more scripts are
converted to built-ins (naturally using the parse-options API, too), so
in practice this catches most issues, and is definitely the biggest bang
for the buck.

To use the singular form of a word, when the option wants the plural
form (and quietly expands it because it thinks it was abbreviated), is
an easy mistake to make, and t5317 contains almost two dozen of them.
However, using abbreviated options in tests is a bit fragile, so we will
disallow use of abbreviated options in our test suite.

It was probably just an oversight: the `--recurse-submodules` option
puts the term "submodules" in the plural form, not the singular one.

This test wants to run `git rebase` with the `--keep-empty` option, but
it really only spelled out `--keep` and trusted Git's option parsing to
determine that this was a unique abbreviation of the real option.
However, Denton Liu contributed a patch series in
https://public-inbox.org/git/cover.1553354374.git.liu.denton@gmail.com/
that introduces a new `git rebase` option called `--keep-base`, which
makes this previously unique abbreviation non-unique.
Whether this patch series is accepted or not, it is actually a bad
practice to use abbreviated options in our test suite, because of the
issue that those unique option names are not guaranteed to stay unique
in the future.
So let's just not use abbreviated options in the test suite.

The current wildmatch() call for includeIf's gitdir pattern does not
pass the WM_PATHNAME flag. Without this flag, '*' is treated _almost_
the same as '**' (because '*' also matches slashes) with one exception:
'/**/' can match a single slash. The pattern 'foo/**/bar' matches
'foo/bar'.
But '/*/', which is essentially what wildmatch engine sees without
WM_PATHNAME, has to match two slashes (and '*' matches nothing). Which
means 'foo/*/bar' cannot match 'foo/bar'. It can only match 'foo//bar'.
The result of this is the current wildmatch() call works most of the
time until the user depends on '/**/' matching no path component. And
also '*' matches slashes while it should not, but people probably
haven't noticed this yet. The fix is straightforward.

Don't redundantly run "git reflog expire --all" when gc.reflogExpire
and gc.reflogExpireUnreachable are set to "never", and die immediately
if those configuration valuer are bad.
As an earlier "assert lack of early exit" change to the tests for "git
reflog expire" shows, an early check of gc.reflogExpire{Unreachable,}
isn't wanted in general for "git reflog expire", but it makes sense
for "gc" because:
1) Similarly to 8ab5aa4bd8 ("parseopt: handle malformed --expire
arguments more nicely", 2018-04-21) we'll now die early if the
config variables are set to invalid values.
We run "pack-refs" before "reflog expire", which can take a while,
only to then die on an invalid gc.reflogExpire{Unreachable,}
configuration.
2) Not invoking the command at all means it won't show up in trace
output, which makes what's going on more obvious when the two are
set to "never".
3) As a later change documents we lock the refs when looping over the
refs to expire, even in cases where we end up doing nothing due to
this config.
For the reasons noted in the earlier "assert lack of early exit"
change I don't think it's worth it to bend over backwards in "git
reflog expire" itself to carefully detect if we'll really do
nothing given the combination of all its possible options and skip
that locking, but that's easy to detect here in "gc" where we'll
only run "reflog expire" in a relatively simple mode.

When gc.reflogExpire and gc.reflogExpireUnreachable are set to "never"
and --stale-fix isn't in effect we *could* exit early without
pointlessly looping over all the reflogs.
However, as an earlier change to add a test for the "points nowhere"
warning shows even in such a mode we might want to print out a
warning.
So while it's conceivable to implement this, I don't think it's worth
it. It's going to be too easy to inadvertently add some flag that'll
make the expiry happen anyway, and even with "never" we'd like to see
all the lines we're going to keep.
So let's assert that we're going to loop over all the references even
when this configuration is in effect.

When --merge is specified, we may need to do a real merge (instead of
three-way tree unpacking), the steps are best seen in git-checkout.sh
version before it's removed:
# Match the index to the working tree, and do a three-way.
git diff-files --name-only | git update-index --remove --stdin &&
work=`git write-tree` &&
git read-tree $v --reset -u $new || exit
git merge-recursive $old -- $new $work
# Do not register the cleanly merged paths in the index yet.
# this is not a real merge before committing, but just carrying
# the working tree changes along.
unmerged=`git ls-files -u`
git read-tree $v --reset $new
case "$unmerged" in
'') ;;
*)
(
z40=0000000000000000000000000000000000000000
echo "$unmerged" |
sed -e 's/^[0-7]* [0-9a-f]* /'"0 $z40 /"
echo "$unmerged"
) | git update-index --index-info
;;
esac
Notice the last 'read-tree --reset' step. We restore worktree back to
'new' tree after worktree's messed up by merge-recursive. If there are
staged changes before this whole command sequence is executed, they
are lost because they are unlikely part of the 'new' tree to be
restored.
There is no easy way to fix this. Elijah may have something up his
sleeves [1], but until then, check if there are staged changes and
refuse to run and lose them. The user would need to do "git reset" to
continue in this case.
A note about the test update. 'checkout -m' in that test will fail
because a deletion is staged. This 'checkout -m' was previously needed
to verify quietness behavior of unpack-trees. But a different check
has been put in place in the last patch. We can safely drop
'checkout -m' now.

read-tree is basically the front end of unpack-trees code and shoud
expose all of its functionality (unless it's designed for internal
use). This "opts.quiet" (formerly "opts.gently") was added for
builtin/checkout.c but there is no reason why other read-tree users
won't find this useful.
The test that is updated to run 'read-tree --quiet' was added because
unpack-trees was accidentally not being quiet [1] in 6a143aa2b2
(checkout -m: attempt merge when deletion of path was staged -
2014-08-12). Because checkout is the only "opts.quiet" user, there was
no other way to test quiet behavior. But we can now test it directly.
6a143aa2b2 was manually reverted to verify that read-tree --quiet
works correctly (i.e. test_must_be_empty fails).
[1] the commit message there say "errors out instead of performing a
merge" but I'm pretty sure the "performing a merge" happens anyway
even before that commit. That line should say "errors out
_in addition to_ performing a merge"

When using protocol v0, upload-pack over HTTP permits a "half-auth"
configuration in which, at the web server layer, the info/refs path is
not protected by authentication but the git-upload-pack path is, so that
a user can perform fetches that do not download any objects without
authentication, but still needs authentication to download objects.
But protocol v2 does not support this, because both ref and pack are
obtained from the git-upload-pack path.
Mark the test verifying this behavior as protocol v0-only, with a
description of what needs to be done to make v2 support this.
