ci(visual-studio): actually run the tests in parallel

Originally, the CI/PR builds that build and test using Visual Studio
were implemented imitating `linux-clang`, i.e. still using the
`Makefile`-based build infrastructure.

Later (but still before the patches made their way into git.git's
`master`), however, this was changed to generate Visual Studio project
files and build the binaries using `MSBuild`, as this reflects more
accurately how Visual Studio users would want to build Git (internally,
Visual Studio uses `MSBuild`, or at least something very similar).

During that transition, we needed to implement a new way to run the test
suite in parallel, as Visual Studio users typically will only have a Git
Bash available (which does not ship with `make` nor with support for
`prove`): we simply implemented a new test helper to run the test suite.

This helper even knows how to run the tests in parallel, but due to a
mistake on this developer's part, it was never turned on in the CI/PR
builds. This results in 2x-3x longer run times of the test phase.

Let's use the `--jobs=10` option to fix this.

To make full use of the work that went into the Visual Studio build &

will give us the benefit of Visual C's compiler warnings (which, at
times, seem to catch things that GCC does not catch, and vice versa).

While at it, also turn on optimization; It does not make sense to
produce binaries with debug information, and we can use any ounce of
speed that we get (because the test suite is particularly slow on
Windows, thanks to the need to run inside a Unix shell, which

userdiff: fix some corner cases in dts regex

While reviewing some dts diffs recently I noticed that the hunk header
logic was failing to find the containing node. This is because the regex
doesn't consider properties that may span multiple lines, i.e.

property = <something>,
   <something_else>;

and it got hung up on comments inside nodes that look like the root node
because they start with '/*'. Add tests for these cases and update the
regex to find them. Maybe detecting the root node is too complicated but
forcing it to be a backslash with any amount of whitespace up to an open
bracket seemed OK. I tried to detect that a comment is in-between the
two parts but I wasn't happy so I just dropped it.

test-progress: fix test failures on big-endian systems

In 't0500-progress-display.sh' all tests running 'test-tool progress
--total=<N>' fail on big-endian systems, e.g. like this:

  + test-tool progress --total=3 Working hard
  [...]
  + test_i18ncmp expect out
  --- expect 2019-10-18 23:07:54.765523916 +0000
  +++ out 2019-10-18 23:07:54.773523916 +0000
  @@ -1,4 +1,2 @@
  -Working hard:  33% (1/3)<CR>
  -Working hard:  66% (2/3)<CR>
  -Working hard: 100% (3/3)<CR>
  -Working hard: 100% (3/3), done.
  +Working hard:   0% (1/12884901888)<CR>
  +Working hard:   0% (3/12884901888), done.

The reason for that bogus value is that '--total's parameter is parsed
via parse-options's OPT_INTEGER into a uint64_t variable [1], so the
two bits of 3 end up in the "wrong" bytes on big-endian systems
(12884901888 = 0x300000000).

Change the type of that variable from uint64_t to int, to match what
parse-options expects; in the tests of the progress output we won't
use values that don't fit into an int anyway.

[1] start_progress() expects the total number as an uint64_t, that's
    why I chose the same type when declaring the variable holding the
    value given on the command line.

empty list.  This only has consequences for invalid delete requests

after the loop.

Once we found the item's predecessor in the list, update its next
pointer to skip over the item, which removes it from the list.  In other
words: Make the item's successor the successor of its predecessor.

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.

The text is taken mostly verbatim from:

  https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

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.

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
up-to-date with the upstream of the branch being pushed.

range-diff: don't segfault with mode-only changes

In ef283b3699 ("apply: make parse_git_diff_header public", 2019-07-11)
the 'parse_git_diff_header' function was made public and useable by

However it was missed that its (then) only caller, 'find_header' did

range-diff then started using this function, and tried to handle this

Move the error handling and completing of the struct into the

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

ancestor_name = $SOMETHING
empty loop over merge_bases...
opt->ancestor = ancestor_name
        merge_trees_internal()

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.
