perf/run: learn to send output to codespeed server
Let's make it possible to set in a config file the URL of

send the perf test results to this URL at the end of the
tests.
This should make is possible to easily automate the process

send-email: add and use a local copy of Mail::Address
We used to have two versions of the email parsing code. Our
parse_mailboxes (in Git.pm), and Mail::Address which we used if
installed. Unfortunately, both versions have different sets of bugs, and
changing the behavior of git depending on whether Mail::Address is
installed was a bad idea.
A first attempt to solve this was cc90750 (send-email: don't use
Mail::Address, even if available, 2017-08-23), but it turns out our
parse_mailboxes is too buggy for some uses. For example the lack of
nested comments support breaks get_maintainer.pl in the Linux kernel
tree:
This patch goes the other way: use Mail::Address anyway, but have a
local copy from CPAN as a fallback, when the system one is not
available.
The duplicated script is small (276 lines of code) and stable in time.
Maintaining the local copy should not be an issue, and will certainly be
less burden than maintaining our own parse_mailboxes.
Another option would be to consider Mail::Address as a hard dependency,
but it's easy enough to save the trouble of extra-dependency to the end
user or packager.

2010-08-23) we were hesitant to check if the user requests both -S and

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

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 order to italicize the `$path` argument the commands are enclosed in

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

clone: do not clean up directories we didn't create
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.

travis-ci: record and skip successfully built trees
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.

travis-ci: save prove state for the 32 bit Linux build
This change follows suit of 6272ed319 (travis-ci: run previously
failed tests first, then slowest to fastest, 2016-01-26), which did
this for the Linux and OSX build jobs. Travis CI build jobs run the
tests parallel, which is sligtly faster when tests are run in slowest
to fastest order, shortening the overall runtime of this build job by
about a minute / 10%.
Note, that the 32 bit Linux build job runs the tests suite in a Docker
container and we have to share the Travis CI cache directory with the
container as a second volume. Otherwise we couldn't use a symlink
pointing to the prove state file in the cache directory, because
that's outside of the directory hierarchy accessible from within the
container.

travis-ci: don't install default addon packages for the 32 bit Linux build
The 32 bit Linux build job compiles Git and runs the test suite in a
Docker container, while the additional packages (apache2, git-svn,
language-pack-is) are installed on the host, therefore don't have
any effect and are unnecessary.

travis-ci: fine tune the use of 'set -x' in 'ci/*' scripts
The change in commit 4f2636667 (travis-ci: use 'set -x' in 'ci/*'
scripts for extra tracing output, 2017-12-12) left a couple of rough
edges:
- 'ci/run-linux32-build.sh' is executed in a Docker container and
therefore doesn't source 'ci/lib-travisci.sh', which would enable
tracing executed commands. Enable 'set -x' in this script, too.
- 'ci/print-test-failures.sh' iterates over all the files containing
the exit codes of all the executed test scripts. Since there are
over 800 such files, the loop produces way too much noise with
tracing executed commands enabled, so disable 'set -x' for this
script.
- 'ci/run-windows-build.sh' busily waits in a loop for the result of
the Windows build, producing too much noise with tracing executed
commands enabled as well. Disable 'set -x' for the duration of
that loop.
