We already have pread emulation for portability, so there's
there's no reason to make two syscalls where one suffices.

There are a couple of reserved names that cannot be file names on
Windows, such as `AUX`, `NUL`, etc. For an almost complete list, see
https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file
If one would try to create a directory named `NUL`, it would actually
"succeed", i.e. the call would return success, but nothing would be
created.
Worse, even adding a file extension to the reserved name does not make
it a valid file name. To understand the rationale behind that behavior,
see https://devblogs.microsoft.com/oldnewthing/20031022-00/?p=42073
Let's just disallow them all.

In the next commit, we want to disallow accessing any path that contains
any segment that is equivalent to `NUL`. In particular, we want to
disallow accessing `NUL` (e.g. to prevent any repository from being
checked out that contains a file called `NUL`, as that is not a valid
file name on Windows).
However, there are legitimate use cases within Git itself to write to
the Null device. As Git is really a Linux project, it does not abstract
that idea, though, but instead uses `/dev/null` to describe this
intention.
So let's side-step the validation _specifically_ in the case that we
want to write to (or read from) `/dev/null`, via a dedicated short-cut
in the code that skips the call to `validate_win32_path()`.

The built-in `git add -i` machinery obviously has its `the_repository`
structure initialized at the point where `cmd_commit()` calls it, and
therefore does not look at the environment variable `GIT_INDEX_FILE`.
But when being called from `commit --interactive`, it has to, because
the index was already locked in that case, and we want to ask the
interactive add machinery to work on the `index.lock` file instead of
the `index` file.
Technically, we could teach `run_add_i()`, or for that matter
`run_add_p()`, to look specifically at that environment variable, but
the entire idea of passing in a parameter of type `struct repository *`
is to allow working on multiple repositories (and their index files)
independently.
So let's instead override the `index_file` field of that structure
temporarily.

This patch teaches the built-in `git add -p` machinery all the tricks it
needs to know in order to act as the work horse for `git checkout -p`.
Apart from the minor changes (slightly reworded messages, different
`diff` and `apply --check` invocations), it requires a new function to
actually apply the changes, as `git checkout -p` is a bit special in
that respect: when the desired changes do not apply to the index, but
apply to the work tree, Git does not fail straight away, but asks the
user whether to apply the changes to the worktree at least.

The scripted version of `git stash` called directly into the Perl script
`git-add--interactive.perl`, and this was faithfully converted to C.
However, we have a much better way to do this now: call the internal API
directly, which will now incidentally also respect the
`add.interactive.useBuiltin` setting. Let's just do this.
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
As `git add` traditionally did not expose the `--patch=<mode>` modes via
command-line options, the scripted version of `git stash` had to call
`git add--interactive` directly.
But this prevents the built-in `add -p` from kicking in, as
`add--interactive` is the scripted version (which does not have a
"fall-back" to the built-in version).
So let's introduce support for internal switch for `git add` that the
scripted `git stash` can use to call the appropriate backend (scripted
or built-in, depending on `add.interactive.useBuiltin`).

The `git stash` and `git reset` commands support a `--patch` option, and
both simply hand off to `git add -p` to perform that work. Let's teach

Signed-off-by: Junio C Hamano <gitster@pobox.com>
The Perl script backing `git add -p` is used not only for that command,
but also for `git stash -p`, `git reset -p` and `git checkout -p`.
In preparation for teaching the C version of `git add -p` to support
also the latter commands, let's abstract away what is "stage" specific
into a dedicated data structure describing the differences between the
patch modes.
Finally, please note that the Perl version tries to make sure that the
diffs are only generated for the modified files. This is not actually
necessary, as the calls to Git's diff machinery already perform that
work, and perform it well. This makes it unnecessary to port the
`FILTER` field of the `%patch_modes` struct, as well as the
`get_diff_reference()` function.

The shebang path for the Perl interpreter in git-credential-netrc was
hardcoded. However, some users may have it located at a different
location and thus, would have had to manually edit the script.
Add a .perl prefix to the script to denote it as a template and ignore
the generated version. Augment the Makefile so that it generates
git-credential-netrc from git-credential-netrc.perl, just like other
Perl scripts.
The Makefile recipes were shamelessly stolen from
contrib/mw-to-git/Makefile.

Before, we were running `test_must_fail full_name`. However,
`test_must_fail` should only be used on git commands. Inline full_name()
so that we can use test_must_fail on the git command directly.
When full_name() was introduced in 28fb84382b (Introduce
<branch>@{upstream} notation, 2009-09-10), the `git -C` option wasn't
available yet (since it was introduced in 44e1e4d67d (git: run in a
directory given with -C option, 2013-09-09)). As a result, the helper
function removed the need to manually cd each time. However, since
`git -C` is available now, we can just use that instead and inline
full_name().
An alternate approach was taken where we taught full_name() to accept an
optional `!` arg to trigger test_must_fail behavior. However, this added
more unnecessary complexity than inlining so we inline instead.

The expected test style is to have all commands tested within a
test_expect_success block. Move the generation of the 'expect' text into
their corresponding blocks. While we're at it, insert a second
`commit=$(git rev-parse HEAD)` into the next test case so that it's
clear where $commit is coming from.
The biggest advantage of doing this is that we now check the return code
of `git rev-parse HEAD` so we can catch it in case it fails.
This patch is best viewed with `--color-moved --ignore-all-space`.

The return code of git commands are lost when a command is in a
non-assignment command substitution in favour of the surrounding
command's. Rewrite instances of this so that git commands run
on their own.
In commit_subject(), use a `tformat` instead of `format` since,
previously, we were testing the output of a command substitution which
didn't care if there was a trailing newline since it was automatically
stripped. Since we use test_cmp() now, the trailing newline matters so
use `tformat` to always output it.

The test_must_fail() family of functions (including test_might_fail())
should only be used on git commands. Replace test_might_fail() with
a compound command wrapping the old cp invocation that always returns 0.
The `test_might_fail cp` line was introduced in 466e8d5d66 (t1501: fix
test with split index, 2015-03-24). It is necessary because there might
exist some index files in `repo.git/sharedindex.*` and, if they exist,
we want to copy them over. However, if they don't exist, we don't want
to error out because we expect that possibility. As a result, we want to
keep the "might fail" semantics so we always return 0, even if the
underlying cp errors out.
