add a Code of Conduct document
We've never had a formally written Code of Conduct document. Though it
has been discussed off and on over the years, for the most part the
behavior on the mailing list has been good enough that nobody felt the
need to push one forward.
However, even if there aren't specific problems now, it's a good idea to
have a document:
- it puts everybody on the same page with respect to expectations.
This might avoid poor behavior, but also makes it easier to handle
it if it does happen.
- it publicly advertises that good conduct is important to us and will
be enforced, which may make some people more comfortable with
joining our community
- it may be a good time to cement our expectations when things are
quiet, since it gives everybody some distance rather than focusing
on a current contentious issue
This patch adapts the Contributor Covenant Code of Conduct. As opposed
to writing our own from scratch, this uses common and well-accepted
language, and strikes a good balance between illustrating expectations
and avoiding a laundry list of behaviors. It's also the same document
used by the Git for Windows project.
I also stole a very nice introductory paragraph from the Git for Windows
version of the file.
There are a few subtle points, though:
- the document refers to "the project maintainers". For the code, we
generally only consider there to be one maintainer: Junio C Hamano.
But for dealing with community issues, it makes sense to involve
more people to spread the responsibility. I've listed the project
committee address of git@sfconservancy.org as the contact point.
- the document mentions banning from the community, both in the intro
paragraph and in "Our Responsibilities". The exact mechanism here is
left vague. I can imagine it might start with social enforcement
(not accepting patches, ignoring emails) and could escalate to
technical measures if necessary (asking vger admins to block an
address). It probably make sense _not_ to get too specific at this
point, and deal with specifics as they come up.

send-pack: never fetch when checking exclusions
When building the packfile to be sent, send_pack() is given a list of
remote refs to be used as exclusions. For each ref, it first checks if
the ref exists locally, and if it does, passes it with a "^" prefix to
pack-objects. However, in a partial clone, the check may trigger a lazy
fetch.
The additional commit ancestry information obtained during such fetches
may show that certain objects that would have been sent are already
known to the server, resulting in a smaller pack being sent. But this is
at the cost of fetching from many possibly unrelated refs, and the lazy
fetches do not help at all in the typical case where the client is

merge-recursive: fix the fix to the diff3 common ancestor label
In commit 8e4ec337 ("merge-recursive: fix the diff3 common ancestor
label for virtual commits", 2019-10-01), which was a fix to commit 743474cbfa8b ("merge-recursive: provide a better label for diff3
common ancestor", 2019-08-17), the label for the common ancestor was
changed from always being
"merged common ancestors"
to instead be based on the number of merge bases and whether the merge
base was a real commit or a virtual one:
>=2: "merged common ancestors"
1, via merge_recursive_generic: "constructed merge base"
1, otherwise: <abbreviated commit hash>
0: "<empty tree>"
The handling for "constructed merge base" worked by allowing
opt->ancestor to be set in merge_recursive_generic(), so we paid
attention to the setting of that variable in merge_recursive_internal().
Now, for the outer merge, the code flow was simply the following:
ancestor_name = "merged merge bases"
loop over merge_bases: merge_recursive_internal()
The first merge base not needing recursion would determine its own
ancestor_name however necessary and thus run
Now, the next set of merge_bases that would need to be merged after this
particular merge had completed would note that opt->ancestor has been
set to something (to a local ancestor_name variable that has since been
popped off the stack), and thus it would run:
... else if (opt->ancestor) {
ancestor_name = opt->ancestor; /* OOPS! */
loop over merge_bases: merge_recursive_internal()
opt->ancestor = ancestor_name
merge_trees_internal()
This resulted in garbage strings being printed for the virtual merge
bases, which was visible in git.git by just merging commit b744c3af07
into commit 6d8cb22a4f. There are two ways to fix this: set
opt->ancestor to NULL after using it to avoid re-use, or add a
!opt->priv->call_depth check to the if block for using a pre-defined
opt->ancestor. Apply both fixes.

immediately exit the test script. Together with `--write-junit-xml`, we
will want the JUnit-style `.xml` file to be finalized (and not leave the
XML incomplete). Let's make it so.
This comes in particularly handy when trying to debug via Azure
Pipelines, where the JUnit-style XML is consumed to present the test
results in an informative and helpful way.
While at it, also handle the `error()` code path.
The only remaining code path that sets `GIT_EXIT_OK` happens whenever
the trash directory could not be set up, i.e. long before the JUnit XML
was written, therefore we should _not_ try to finalize that XML in that
case.
It is tempting to change the `immediate` code path to just hand off to
`error`, simplifying the code in the process. That would, however,
result in a change of behavior (an additional error message) in the test
suite, which is outside of the purview of the current patch series: its
goal is to allow building Git with Visual Studio and testing it with a
portable version of Git for Windows.

test-tool run-command: learn to run (parts of) the testsuite
Git for Windows jumps through hoops to provide a development environment
that allows to build Git and to run its test suite. To that end, an
entire MSYS2 system, including GNU make and GCC is offered as "the Git
for Windows SDK". It does come at a price: an initial download of said
SDK weighs in with several hundreds of megabytes, and the unpacked SDK
occupies ~2GB of disk space.
A much more native development environment on Windows is Visual Studio.
To help contributors use that environment, we already have a Makefile
target `vcxproj` that generates a commit with project files (and other
generated files), and Git for Windows' `vs/master` branch is
continuously re-generated using that target.
The idea is to allow building Git in Visual Studio, and to run
individual tests using a Portable Git.
The one missing thing is a way to run the entire test suite: neither
`make` nor `prove` are required to run Git, therefore Git for Windows
does not support those commands in the Portable Git.
To help with that, add a simple test helper that exercises the
`run_processes_parallel()` function to allow for running test scripts in
parallel (which is really necessary, especially on Windows, as Git's
test suite takes such a long time to run).
This will also come in handy for the upcoming change to our Azure
Pipeline: we will use this helper in a Portable Git to test the Visual
Studio build of Git.

In the CI builds, we bundle all generated files into a so-called
artifacts `.tar` file, so that the test phase can fan out into multiple
parallel builds.
This patch makes sure that all files are included in the `vcxproj`
target which are needed for that artifacts `.tar` file.

vcxproj: only copy `git-remote-http.exe` once it was built
In b18ae14a8f6 (vcxproj: also link-or-copy builtins, 2019-07-29), we
started to copy or hard-link the built-ins as a post-build step of the
`git` project.
At the same time, we tried to copy or hard-link `git-remote-http.exe`,
but it is quite possible that it was not built at that time.
Let's move that latter task into a post-install step of the
`git-remote-http` project instead.

msvc: work around a bug in GetEnvironmentVariable()
The return value of that function is 0 both for variables that are
unset, as well as for variables whose values are empty. To discern those
two cases, one has to call `GetLastError()`, whose return value is
`ERROR_ENVVAR_NOT_FOUND` and `ERROR_SUCCESS`, respectively.
Except that it is not actually set to `ERROR_SUCCESS` in the latter
case, apparently, but the last error value seems to be simply unchanged.
To work around this, let's just re-set the last error value just before
inspecting the environment variable.
This fixes a problem that triggers failures in t3301-notes.sh (where we
try to override config settings by passing empty values for certain
environment variables).
This problem is hidden in the MINGW build by the fact that older
MSVC runtimes (such as the one used by MINGW builds) have a `calloc()`
that re-sets the last error value in case of success, while newer
runtimes set the error value only if `NULL` is returned by that
function.

We frequently build Git using the `DEVELOPER=1` make setting as a
shortcut to enable all kinds of more stringent compiler warnings.
Those compiler warnings are relatively specific to GCC, though, so let's
try our best to translate them to the equivalent options to pass to MS
Visual C++'s `cl.exe`.
