mingw: handle a file owned by the Administrators group correctly
When an Administrator creates a file or directory, the created
file/directory is owned not by the Administrator SID, but by the
_Administrators Group_ SID. The reason is that users with administrator
privileges usually run in unprivileged ("non-elevated") mode, and their
user SID does not change when running in elevated mode.
This is is relevant e.g. when running a GitHub workflow on a build
agent, which runs in elevated mode: cloning a Git repository in a script
step will cause the worktree to be owned by the Administrators Group
SID, for example.
Let's handle this case as following: if the current user is an
administrator, Git should consider a worktree owned by the
Administrators Group as if it were owned by said user.

Fix a logic error in a082345372e (hook API: fix v2.36.0 regression:
hooks should be connected to a TTY, 2022-06-07). When it started using
the "ungroup" API added in fd3aaf53f71 (run-command: add an "ungroup"
option to run_process_parallel(), 2022-06-07) it should have made the
same sort of change that fd3aaf53f71 itself made in
"t/helper/test-run-command.c".
The correct way to emit this "Couldn't start" output with "ungroup"
would be:
But we should instead remove the emitting of this output. As the added
test shows we already emit output when we can't run the child. The
"cannot run" output here is emitted by run-command.c's
child_err_spew().
So the addition of the "Couldn't start hook" output here in 96e7225b310 (hook: add 'run' subcommand, 2021-12-22) was always
redundant. For the pre-commit hook we'll now emit exactly the same
output as we did before f443246b9f2 (commit: convert
{pre-commit,prepare-commit-msg} hook to hook.h, 2021-12-22) (and
likewise for others).
We could at this point add this to the pick_next_hook() callbacks in
hook.c:
assert(!out);
assert(!*pp_task_cb);
And this to notify_start_failure() and notify_hook_finished() (in the
latter case the parameter is called "pp_task_cp"):
assert(!out);
assert(!pp_task_cb);
But let's leave any such instrumentation for some eventual cleanup of
the "ungroup" API.

Files' attributes can indicate more than just whether they are files or
directories. It was reported in Git for Windows that on certain network
shares, this led to a nasty problem trying to create tags:
$ git tag -a -m "automatic tag creation" test_dir/test_tag
fatal: cannot lock ref 'refs/tags/test_dir/test_tag': unable to resolve reference 'refs/tags/test_dir/test_tag': Not a directory
Note: This does not necessarily happen with all types of network shares.
One setup where it _did_ happen is a Windows Server 2019 VM, and as
hinted in
This would impact performance negatively, though, as it essentially
turns off all caching, therefore we do not want to require users to do
that just to be able to use Git on Windows.
The underlying bug is in the code added in 4b0abd5c695 (mingw: let
lstat() fail with errno == ENOTDIR when appropriate, 2016-01-26) that
emulates the POSIX behavior where `lstat()` should return `ENOENT` if
the file or directory simply does not exist but could be created, and
`ENOTDIR` if there is no file or directory nor could there be because a
leading path already exists and is not a directory.
In that code, the return value of `GetFileAttributesW()` is interpreted
as an enum value, not as a bit field, so that a perfectly fine leading
directory can be misdetected as "not a directory".
As a consequence, the `read_refs_internal()` function would return
`ENOTDIR`, suggesting not only that the tag in the `git tag` invocation
above does not exist, but that it cannot even be created.
Let's fix the code so that it interprets the return value of the
`GetFileAttributesW()` call correctly.

To do that, we split the non-msysGit part (that targeted MSys1) in two,

overrode it for MSYS2 with the empty value because we very much want to

windows: include the Python bits when building Git for Windows
While Git for Windows does not _ship_ Python (in order to save on
bandwidth), MSYS2 provides very fine Python interpreters that users can
easily take advantage of, by using Git for Windows within its SDK.
Previously, we excluded the Python bits, mostly due to historical
reasons: In the Git for Windows v1.x days, we built Git using
MSys/MinGW, without support for any Python scripts.
Therefore, let's move out the `NO_PYTHON` definition from the generic
part of the MINGW section (which includes special handling for MSYS2/Git
for Windows, for the long-superseded msysGit environment, as well as for
the setup of probably just one developer remaining with their MSys1)
into the two sections that cover different environments than Git for
Windows' SDK.

commit-graph: fix corrupt upgrade from generation v1 to v2
The previous commit demonstrates a bug where a commit-graph using
generation v2 could enter a state where one of the GDA2 values has its
most-significant bit set (indicating that its value should be read from
the extended offset table in the GDO2 chunk) without having a GDO2 chunk
to read from.
This results in the following error message being displayed to the
caller:
fatal: commit-graph requires overflow generation data but has none
This bug arises in the following scenario:
- We decide to write a commit-graph using generation number v2, and
decide (correctly) that no GDO2 chunk is necessary (e.g., because
all of the commiter date offsets are no larger than 2^31-1).
- The v2 generation numbers are stored in the `->generation` member of
the commit slab holding `struct commit_graph_data`'s.
- Later on, `load_commit_graph_info()` is called, overwriting the
v2 generation data in the aforementioned slab with any existing v1
generation data.
Then, when the commit-graph code goes to write the GDA2 chunk via
`write_graph_chunk_generation_data()`, we use the overwritten generation
v1 data in a place where we expect to use a v2 generation number:
...because `commit_graph_data_at(c)->generation` used to hold the v2
generation data, but it was overwritten to contain the v1 generation
number via `load_commit_graph_info()`.
If the `offset` computation above overflows the v2 generation number
max, then `write_graph_chunk_generation_data()` will update its count of
large offsets and write the marker accordingly:
and reads will look for the GDO2 chunk containing the overflowing v2
generation number, *after* the commit-graph code decided that no such
chunk was necessary.
The main problem is that the slab containing `struct commit_graph_data`
has a dual purpose. It is used to hold data that we are about to write
to disk while generating a commit-graph, as well as hold data that was
read from an existing commit-graph.
When the two mix, namely when the result of reading the commit-graph has
a side-effect that mixes poorly with an in-progress commit-graph write,
we end up with corrupt data.
A complete fix might be to introduce a new slab that is used exclusively
for writing, and gate access between the two slabs based on context
provided by the caller (e.g., whether this computation is part of a
"read" or "write" operation).
But a more minimal fix addresses the only known path which overwrites
the slab data, which is `compute_bloom_filters()` ->
`get_or_compute_bloom_filter()` -> `load_commit_graph_info()` ->
`fill_commit_graph_info()` by avoiding the last call which clobbers the
data altogether.
This path only needs to learn the graph position of a given commit so
that it can be used in `load_bloom_filter_from_graph()`. By replacing
the last steps of the above with one that records the graph position
into a temporary variable which is then used to load the existing Bloom
data, we eliminate the clobbering, removing the corruption.

Low-level callers in systems that are adjacent to the commit-graph (like
the changed-path Bloom filter code) could benefit from being able to
call a function like `parse_commit_in_graph()` without modifying the
corresponding commit slab data.
This is useful in contexts where that slab data is being used to prepare
for an upcoming commit-graph write, where Git must be careful to avoid
clobbering any of that data during a read operation.
Introduce a low-level variant of `parse_commit_in_graph()` which returns
the graph position of a given commit only, without modifying any of the
slab data.

When upgrading a commit-graph using generation v1 to one using
generation v2, it is possible to force Git into a corrupt state where it
(incorrectly) believes that a GDO2 chunk is necessary, *after* deciding
not to write one.
This makes subsequent reads using the commit-graph produce the following
error message:
fatal: commit-graph requires overflow generation data but has none
Demonstrate this bug by increasing our test coverage to include a
minimal example of upgrading a commit-graph from generation v1 to v2.
The only notable components of this test are:
- The committer date of the commit is chosen carefully so that the
offset underflows when computed using a v1 generation number, but
would not overflow when using v2 generation numbers.
- The upgrade to generation number v2 must read in the v1 generation
numbers, which we can do by passing `--changed-paths`, which will
force the commit-graph internals to call `fill_commit_graph_info()`.
A future patch will squash this bug.

When sorting the output of `git shortlog` by count, a list of authors in
alphabetical order is then sorted by contribution count. Obviously, the
idea is to maintain the alphabetical order for items with identical
contribution count.
At the moment, this job is performed by `qsort()`. As that function is
not guaranteed to implement a stable sort algorithm, this can lead to
inconsistent and/or surprising behavior: items with identical
contribution count could lose their alphabetical sub-order.
The `qsort()` in MS Visual C's runtime does _not_ implement a stable
sort algorithm, and under certain circumstances this even causes a test
failure in t4201.21 "shortlog can match multiple groups", where two

mergetool(vimdiff): allow paths to contain spaces again
In 0041797449d (vimdiff: new implementation with layout support,
2022-03-30), we introduced a completely new implementation of the
`vimdiff` backend for `git mergetool`.
In this implementation, we no longer call `vim` directly but we
accumulate in the variable `FINAL_CMD` an arbitrary number of commands
for `vim` to execute, which necessitates the use of `eval` to split the
commands properly into multiple command-line arguments.
That same `eval` command also needs to pass the paths to `vim`, and
while it looks as if they are quoted correctly, that quoting only
reaches the `eval` instruction and is lost after that, therefore paths
that contain whitespace characters (or other characters that are
interpreted by the POSIX shell) are handled incorrectly.
This is a simple reproducer:
git init -b main bam-merge-fail
cd bam-merge-fail
echo a>"a file.txt"
git add "a file.txt"
git commit -m "added 'a file.txt'"
echo b>"a file.txt"
git add "a file.txt"
git commit -m "diverged b 'a file.txt'"
git checkout -b c HEAD~
echo c>"a file.txt"
git add "a file.txt"
git commit -m "diverged c 'a file.txt'"
git checkout main
git merge c
git mergetool --tool=vimdiff
With Git v2.37.0/v2.37.1, this will open 7 buffers, not four, and not
display the correct contents at all.
To fix this, let's not expand the variables containing the path
parameters before passing them to the `eval` command, but let that
command expand the variables instead.
