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.

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
cd with\ spaces
make -j15 test
Let's fix this.

049e64aa50 ("Documentation: convert SubmittingPatches to AsciiDoc",
2017-11-12) changed the `git blame` and `git shortlog` examples given in
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.

Once upon a time, git-clone would refuse to write into a
directory that it did not itself create. The cleanup
routines for a failed clone could therefore just remove the
git and worktree dirs completely.
In 55892d2398 (Allow cloning to an existing empty directory,
2009-01-11), we learned to write into an existing directory.
Which means that doing:
mkdir foo
git clone will-fail foo
ends up deleting foo. This isn't a huge catastrophe, since
by definition foo must be empty. But it's somewhat
confusing; we should leave the filesystem as we found it.
Because we know that the only directory we'll write into is
an empty one, we can handle this case by just passing the
KEEP_TOPLEVEL flag to our recursive delete (if we could
write into populated directories, we'd have to keep track of
what we wrote and what we did not, which would be much
harder).
Note that we need to handle the work-tree and git-dir
separately, though, as only one might exist (and the new
tests in t5600 cover all cases).

Two parts of git-clone's setup logic check whether a
directory exists, and they both call stat directly with the
same scratch "struct stat" buffer. Let's pull that into a
helper, which has a few advantages:
- it makes the purpose of the stat calls more obvious
- it makes it clear that we don't care about the
information in "buf" remaining valid
- if we later decide to make the check more robust (e.g.,
complaining about non-directories), we can do it in one
place
Note that we could just use file_exists() for this, which
has identical code. But we specifically care about
directories, so this future-proofs us against that function
later getting more picky about seeing actual files.

Every once in a while our explicit .gitignore files get out of sync
when our build process learns to create new artifacts, like test

accordingly.
Use Travis CI to help catch such issues earlier: check that there are
no untracked files at the end of any build jobs building Git (i.e. the
64 bit Clang and GCC Linux and OSX build jobs, plus the GETTEXT_POISON
and 32 bit Linux build jobs) or its documentation, and fail the build

The Clang and GCC 64 bit Linux build jobs download and store the P4
and Git LFS executables under the current directory, which is the
working tree that we are about to build and test. This means that Git
commands like 'status' or 'ls-files' would list these files as
untracked. The next commit is about to make sure that there are no
untracked files present after the build, and the downloaded
executables in the working tree are interfering with those upcoming
checks.
Therefore, let's download P4 and Git LFS in the home directory,
outside of the working tree.

PERLLIB_EXTRA was introduced in v1.9-rc0~88^2 (2013-11-15) as a way
for packagers to add additional directories such as the location of
Subversion's perl bindings to Git's perl path. Since 20d2a30f
(Makefile: replace perl/Makefile.PL with simple make rules,
2012-12-10) setting that variable breaks perl-based commands instead:
$ PATH=$HOME/opt/git/bin:$PATH
$ make install prefix=$HOME/opt/git PERLLIB_EXTRA=anextralibdir
[...]
$ head -2 $HOME/opt/git/libexec/git-core/git-add--interactive
#!/usr/bin/perl
use lib (split(/:/, $ENV{GITPERLLIB} || ":helloiamanextrainstlibdir" || "/usr/local/google/home/jrn/opt/git/share/perl5"));
$ git add -p
Empty compile time value given to use lib at /home/jrn/opt/git/libexec/git-core/git-add--interactive line 2.
Removing the spurious ":" at the beginning of ":$PERLLIB_EXTRA" avoids
the "Empty compile time value" error but with that tweak the problem
still remains: PERLLIB_EXTRA ends up replacing instead of
supplementing the perllibdir that would be passed to 'use lib' if
PERLLIB_EXTRA were not set.
The intent was to simplify, as the commit message to 20d2a30f
explains:
| The scripts themselves will 'use lib' the target directory, but if
| INSTLIBDIR is set it overrides it. It doesn't have to be this way,
| it could be set in addition to INSTLIBDIR, but my reading of
| [v1.9-rc0~88^2] is that this is the desired behavior.
Restore the previous code structure to make PERLLIB_EXTRA work again.
Reproducing this problem requires an invocation of "make install"
instead of running bin-wrappers/git in place, since the latter sets
the GITPERLLIB environment variable, avoiding trouble.

Travis CI dutifully builds and tests each new branch tip, even if its
tree has previously been successfully built and tested. This happens
often enough in contributors' workflows, when a work-in-progress
branch is rebased changing e.g. only commit messages or the order or
number of commits while leaving the resulting code intact, and is then
pushed to a Travis CI-enabled GitHub fork.
This is wasting Travis CI's resources and is sometimes scary-annoying
when the new tip commit with a tree identical to the previous,
successfully tested one is suddenly reported in red, because one of
the OSX build jobs happened to exceed the time limit yet again.
So extend our Travis CI build scripts to skip building commits whose
trees have previously been successfully built and tested. Use the
Travis CI cache feature to keep a record of the object names of trees
that tested successfully, in a plain and simple flat text file, one
line per tree object name. Append the current tree's object name at
the end of every successful build job to this file, along with a bit
of additional info about the build job (commit object name, Travis CI
job number and id). Limit the size of this file to 1000 records, to
prevent it from growing too large for git/git's forever living
integration branches. Check, using a simple grep invocation, in each
build job whether the current commit's tree is already in there, and
skip the build if it is. Include a message in the skipped build job's
trace log, containing the URL to the build job successfully testing
that tree for the first time and instructions on how to force a
re-build. Catch the case when a build job, which successfully built
and tested a particular tree for the first time, is restarted and omit
the URL of the previous build job's trace log, as in this case it's
the same build job and the trace log has just been overwritten.
Note: this won't kick in if two identical trees are on two different
branches, because Travis CI caches are not shared between build jobs
of different branches.

It seems that Travis CI creates the cache directory for us anyway,
even when a previous cache doesn't exist for the current build job.
Alas, this behavior is not explicitly documented, therefore we don't
rely on it and create the cache directory ourselves in those build
jobs that read/write cached data (currently only the prove state).
In the following commit we'll start to cache additional data in every
build job, and will access the cache much earlier in the build
process.
Therefore move creating the cache directory to 'ci/lib-travisci.sh' to
make sure that it exists at the very beginning of every build job.

The leak_pending flag is so awkward to use that multiple comments had to
be added around each occurrence. We only use it for remembering the
commits whose marks we have to clear after checking if the old HEAD is
detached. This is easy, though: We need to do that for the old commit,

Don't bother tracking exactly which commits need their flags cleared,
just nuke all we have in-core. This change is safe because refs can
point at anything, so other program parts can't depend on any kept flags
anyway. And since all refs are loaded we have to basically deal with
all commits anyway, so performance should not be negatively impacted.
