There are various git subcommands (among them, clone) which don't set up
the repository (that is, they lack RUN_SETUP or RUN_SETUP_GENTLY) but
end up needing to have information about the hash algorithm in use.
Because the hash algorithm is part of struct repository and it's only
initialized in repository setup, we can end up dereferencing a NULL
pointer in some cases if we call one of these subcommands and look up
the empty blob or empty tree values.
A "git clone" of a project that has two paths that differ only in
case suffers from this if it is run on a case insensitive platform.
When the command attempts to check out one of these two paths after
checking out the other one, the checkout codepath needs to see if
the version that is already on the filesystem (which should not
happen if the FS were case sensitive) is dirty, and it needs to
exercise the hashing code at that point.
In the future, we can add a command line option for this or read it
from the configuration, but until we're ready to expose that
functionality to the user, simply initialize the repository
structure to use the current hash algorithm, SHA-1.

mingw: handle GITPERLLIB in t0021 in a Windows-compatible way
Git's assumption that all path lists are colon-separated is not only
wrong on Windows, it is not even an assumption that is compatible with
POSIX.
In the interest of time, let's not try to fix this properly but simply
work around the obvious breakage on Windows, where the MSYS2 Bash used
by Git for Windows to interpret the Git's Unix shell scripts will
automagically convert path lists in the environment to
semicolon-separated lists of Windows paths (with drive letter and the
corresponding colon and all that jazz).
In other words, we simply look whether there is a semicolon in
GITPERLLIB and split by semicolons if found instead of colons. This is
not fool-proof, of course, as the path list could consist of a single
path. But that is not the case in Git for Windows' test suite, there are
always two paths in GITPERLLIB.

merge-recursive: do not look at the index during recursive merge
When merging another branch into ours, if their tree is the same as
the common ancestor's, we can declare that our tree represents the
result of three-way merge. In such a case, the recursive merge
backend incorrectly used to create a commit out of our index, even
when the index has changes.
A recent fix attempted to prevent this by adding a comparison
between "our" tree and the index, but forgot that this check must be
restricted only to the outermost merge. Inner merges performed by
the recursive backend across merge bases are by definition made from
scratch without having any local changes added to the index. The
call to index_has_changes() during an inner merge is working on the
index that has no relation to the merge being performed, preventing
legitimate merges from getting carried out.
Fix it by limiting the check to the outermost merge.

diff: properly error out when combining multiple pickaxe options
In f506b8e8b5 (git log/diff: add -G<regexp> that greps in the patch text,
2010-08-23) we were hesitant to check if the user requests both -S and
-G at the same time. Now that the pickaxe family also offers --find-object,
which looks slightly more different than the former two, let's add a check
that those are not used at the same time.

diffcore: add a pickaxe option to find a specific blob
Sometimes users are given a hash of an object and they want to
identify it further (ex.: Use verify-pack to find the largest blobs,
but what are these? or [1])
One might be tempted to extend git-describe to also work with blobs,
such that `git describe <blob-id>` gives a description as
'<commit-ish>:<path>'. This was implemented at [2]; as seen by the sheer
number of responses (>110), it turns out this is tricky to get right.
The hard part to get right is picking the correct 'commit-ish' as that
could be the commit that (re-)introduced the blob or the blob that
removed the blob; the blob could exist in different branches.
Junio hinted at a different approach of solving this problem, which this
patch implements. Teach the diff machinery another flag for restricting
the information to what is shown. For example:
$ ./git log --oneline --find-object=v2.0.0:Makefile b2feb64309 Revert the whole "ask curl-config" topic for now 47fbfded53 i18n: only extract comments marked with "TRANSLATORS:"
we observe that the Makefile as shipped with 2.0 was appeared in v1.9.2-471-g47fbfded53 and in v2.0.0-rc1-5-gb2feb6430b. The
reason why these commits both occur prior to v2.0.0 are evil
merges that are not found using this new mechanism.
Currently the check whether to perform pickaxing is done via checking
`diffopt->pickaxe`, which contains the command line argument that we
want to pickaxe for. Soon we'll introduce a new type of pickaxing, that
will not store anything in the `.pickaxe` field, so let's migrate the
check to be dependent on pickaxe_opts.
It is not enough to just replace the check for pickaxe by pickaxe_opts,
because flags might be set, but pickaxing was not requested ('-i').
To cope with that, introduce a mask to check only for the bits indicating
the modes of operation.

docs/diff-options: clarify scope of diff-filter types
The same document for "--diff-filter" is included by many
programs in the diff family. Because it mentions all
possible types (added, removed, etc), this may imply to the
reader that all types can be generated by a particular
command. But this isn't necessarily the case; "diff-files"
cannot generally produce an "Added" entry, since the diff is
limited to what is already in the index.
Let's make it clear that the list here is the full one, and
does not imply anything about what a particular invocation
may produce.
Note that conditionally including items (e.g., omitting
"Added" in the git-diff-files manpage) isn't the right
solution here for two reasons:
- The problem isn't diff-files, but doing an index to
working tree diff. "git diff" can do the same diff, but
also has other modes where "Added" does show up.
- The direction of the diff matters. Doing "diff-files -R"
can get you Added entries (but not Deleted ones).
So it's best just to explain that the set of available types
depends on the specific diff invocation.

http: fix v1 protocol tests with apache httpd < 2.4
The apache config used by tests was updated to use the SetEnvIf
directive to set the Git-Protocol header in 19113a26b6 ("http: tell
server that the client understands v1", 2017-10-16).
Setting the Git-Protocol header is restricted to httpd >= 2.4, but
mod_setenvif and the SetEnvIf directive work with lower versions, at
least as far back as 2.0, according to the httpd documentation:
Ever since 5b594f457a ("Threaded grep", 2010-01-25) the number of
threads git-grep uses under PTHREADS has been hardcoded to 8, but
there's no performance test to check whether this is an optimal
setting.
Amend the existing tests for the grep engines to support a mode where
this can be tested, e.g.:
When cleaning up files in the $HOME directory, it really makes sense to
quote the path, especially in Git's test suite, where the HOME directory
is *guaranteed* to contain spaces in its name.
It would appear that those two tests pass even without cleaning up the
files, but really more by pure chance than by design (the cleanup seems
not actually to be necessary).
However, if anybody would have a left-over `trash/` directory in Git's
`t/` directory, these tests would fail, because they would all of a
sudden try to delete that directory, but without the `-r` (recursive)
flag. That is how this issue was found.

Allow the test suite to pass in a directory whose name contains spaces
It is totally legitimate to clone Git's source code anywhere, including
into, say, directories whose name (or the name of its absolute path)
contains spaces.
However, a couple of tests failed to anticipate this, for lack of
quoting (or in one instance, for failure to expect more than one space
in the absolute path of the TEST_DIRECTORY). This can be easily verified
by calling these commands in your current clone:
git clone . with\ spaces

the section on sending your patches.
In order to italicize the `$path` argument the commands are enclosed in
plus characters as opposed to backticks. The difference between the
quoting methods is that backtick enclosed text is not subject to further
expansion. This formatting makes reading SubmittingPatches in a git
clone a little more difficult. In addition to the underscores around
`$path` the `--` chars in `git shortlog --no-merges` must be replaced
with `{litdd}`.
Use backticks to quote these commands. The italicized `$path` is lost
from the html version but the commands can be read (and copied) more
easily by users reading the text version. These readers are more likely
to use the commands while submitting patches. Make it easier for them.
