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.

ci(visual-studio): use strict compile flags, and optimization
To make full use of the work that went into the Visual Studio build &
test jobs in our CI/PR builds, let's turn on strict compiler flags. This
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
requires us to use the POSIX emulation layer provided by MSYS2).

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.

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.

94da9193a6 (grep: add support for PCRE v2, 2017-06-01) didn't include
a way to override the system allocator, and so it is incompatible with
custom allocators (e.g. nedmalloc). This problem became obvious when we
tried to plug a memory leak by `free()`ing a data structure allocated by
PCRE2, triggering a segfault in Windows (where we use nedmalloc by
default).
PCRE2 requires the use of a general context to override the allocator
and therefore, there is a lot more code needed than in PCRE1, including
a couple of wrapper functions.
Extend the grep API with a "destructor" that could be called to cleanup
any objects that were created and used globally.
Update `builtin/grep.c` to use that new API, but any other future users
should make sure to have matching `grep_init()`/`grep_destroy()` calls
if they are using the pattern matching functionality.
Move some of the logic that was before done per thread (in the workers)
into an earlier phase to avoid degrading performance, but as the use of
PCRE2 with custom allocators is better understood it is expected more of
its functions will be instructed to use the custom allocator as well as
was done in the original code[1] this work was based on.

63e7e9d8b6 ("git-grep: Learn PCRE", 2011-05-09) didn't include a way
to override the system alocator, and so it is incompatible with
USE_NED_ALLOCATOR as reported by Dscho[1] (in similar code from PCRE2)
Note that nedmalloc, as well as other custom allocators like jemalloc
and mi-malloc, can be configured at runtime (via `LD_PRELOAD`),
therefore we cannot know at compile time whether a custom allocator is
used or not.
Make the minimum change possible to ensure this combination is supported
by extending `grep_init()` to set the PCRE1 specific functions to Git's
idea of `malloc()` and `free()` and therefore making sure all
allocations are done inside PCRE1 with the same allocator than the rest
of Git.
This change has negligible performance impact: PCRE needs to allocate
memory once per program run for the character table and for each pattern
compilation. These are both rare events compared to matching patterns
against lines. Actual measurements[2] show that the impact is lost in
the noise.

remote-curl: pass on atomic capability to remote side
When pushing more than one reference with the --atomic option, the
server is supposed to perform a single atomic transaction to update the
references, leaving them either all to succeed or all to fail. This
works fine when pushing locally or over SSH, but when pushing over HTTP,
we fail to pass the atomic capability to the remote side. In fact, we
have not reported this capability to any remote helpers during the life
of the feature.
Now normally, things happen to work nevertheless, since we actually
check for most types of failures, such as non-fast-forward updates, on
the client side, and just abort the entire attempt. However, if the
server side reports a problem, such as the inability to lock a ref, the
transaction isn't atomic, because we haven't passed the appropriate
capability over and the remote side has no way of knowing that we wanted
atomic behavior.
Fix this by passing the option from the transport code through to remote
helpers, and from the HTTP remote helper down to send-pack. With this
change, we can detect if the server side rejects the push and report
back appropriately. Note the difference in the messages: the remote
side reports "atomic transaction failed", while our own checking rejects
pushes with the message "atomic push failed".
Document the atomic option in the remote helper documentation, so other
implementers can implement it if they like.

fsmonitor: don't fill bitmap with entries to be removed
While doing some testing with fsmonitor enabled I found
that git commands would segfault after staging and
unstaging an untracked file. Looking at the crash it
appeared that fsmonitor_ewah_callback was attempting to
adjust bits beyond the bounds of the index cache.
Digging into how this could happen it became clear that
the fsmonitor extension must have been written with
more bits than there were entries in the index. The
root cause ended up being that fill_fsmonitor_bitmap was
populating fsmonitor_dirty with bits for all entries in
the index, even those that had been marked for removal.
To solve this problem fill_fsmonitor_bitmap has been
updated to skip entries with the the CE_REMOVE flag set.
With this change the bits written for the fsmonitor
extension will be consistent with the index entries
written by do_write_index. Additionally, BUG checks
have been added to detect if the number of bits in
fsmonitor_dirty should ever exceed the number of
entries in the index again.
Another option that was considered was moving the call
to fill_fsmonitor_bitmap closer to where the index is
written (and where the fsmonitor extension itself is
written). However, that did not work as the
fsmonitor_dirty bitmap must be filled before the index
is split during writing.

lets you easily _know_ if you're in the situation mentioned above. And
it's just convenient to list who's involved in the process, since the
project committee list is not anywhere else in the repository.

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
up-to-date with the upstream of the branch being pushed.
Ensure that these lazy fetches do not occur.

t4014: treat rev-list output as the expected value
In 6bd26f58ea (t4014: use test_line_count() where possible, 2019-08-27),
we converted many test cases to take advantage of the test_line_count()
function. In one conversion, we inverted the expected and actual value
as tested by test_line_count(). Although functionally correct, if
format-patch ever produced incorrect output, the debugging output would
be a bunch of hashes which would be difficult to debug.
Invert the expected and actual values provided to test_line_count() so
that if format-patch produces incorrect output, the debugging output
will be a list of human-readable files instead.

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
callers outside of apply.c.
However it was missed that its (then) only caller, 'find_header' did
some error handling, and completing 'struct patch' appropriately.
range-diff then started using this function, and tried to handle this
appropriately itself, but fell short in some cases. This in turn
would lead to range-diff segfaulting when there are mode-only changes
in a range.
Move the error handling and completing of the struct into the
'parse_git_diff_header' function, so other callers can take advantage
of it. This fixes the segfault in 'git range-diff'.

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.
