Some codepaths used fopen(3) when opening a fixed path in $GIT_DIR
(e.g. COMMIT_EDITMSG) that is meant to be left after the command is
done. This however did not work well if the repository is set to

This function has evolved quite a bit over time, and as a
result, the logic for "is this an OK ident" has been
sprinkled throughout. This ends up with a lot of redundant
conditionals, like checking want_name repeatedly. Worse,
we want to know in many cases whether we are using the
"default" ident, and we do so by comparing directly to the
global strbuf, which violates the abstraction of the
ident_default_* functions.
Let's reorganize the function into a hierarchy of
conditionals to handle similar cases together. The only
case that doesn't just work naturally for this is that of an
empty name, where our advice is different based on whether
we came from ident_default_name() or not. We can use a
simple flag to cover this case.

On Windows, there is no SIGPIPE. A consequence of this is that the
upstream process of a pipe does not notice the death of the downstream
process until the pipe buffer is full and writing more data returns an
error. This behavior is the reason for an annoying delay during the
execution of t7610-mergetool.sh: There are a number of test cases where
'yes' is invoked upstream. Since the utility is basically an endless
loop it runs, on Windows, until the pipe buffer is full. This does take
a few seconds.
The test suite has its own implementation of 'yes'. Modify it to produce
only a limited amount of output that is sufficient for the test suite.
The amount chosen should be sufficiently high for any test case, assuming
that future test cases will not exaggerate their demands of input from
an upstream 'yes' invocation.

As a short option, we cannot handle negation. Thus a callback
handling "unset" is overkill, and we can just use OPT_SET_INT
instead to handle setting the option.
Anybody who adds "--nul" synonym to this later would need to be

terminated with LF at the end.

We do not really expect people to use "--no-stage", but if
they do, git currently segfaults. We could instead have it
undo the effects of a previous "--stage", but this gets
tricky around the "to_tempfile" flag. We cannot simply reset
it to 0, because we don't know if it was set by a previous
"--stage=all" or an explicit "--temp" option.
We could solve this by setting a flag and resolving
to_tempfile later, but it's not worth the effort. Nobody
actually wants to use "--no-stage"; we are just trying to
fix a potential segfault here.
While we're in the area, let's improve the user-facing
messages for this option. The error string should be
translatable, and we should give some hint in the "-h"
output about what can go in the argument field.

The parsing of "--index" is done in a callback, but it does
not handle an "unset" option. We don't necessarily expect
anyone to use this, but the current behavior is to treat it
exactly like "--index", which would probably be surprising.
Instead, let's just turn it into an OPT_BOOL, and handle it
after we're done parsing. This makes "--no-index" just work
(it cancels a previous "--index").
As a bonus, this makes the logic easier to follow. The old
code opened the index during the option parsing, leaving the
reader to wonder if there was some timing issue (there
isn't; none of the other options care that we've opened it).
And then if we found that "--prefix" had been given, we had
to rollback the index. Now we can simply avoid opening it in
the first place.
Note that it might make more sense for checkout-index to
complain when "--index --prefix=foo" is given (rather than
silently ignoring "--index"), but since it has been that way
since 415e96c ([PATCH] Implement git-checkout-cache -u to
update stat information in the cache., 2005-05-15), it's
safer to leave it as-is.

We use a custom callback to parse "--prefix", but it does
not handle the "unset" case. As a result, passing
"--no-prefix" will cause a segfault.
We can fix this by switching it to an OPT_STRING, which
makes "--no-prefix" counteract a previous "--prefix". Note
that this assigns NULL, so we bump our default-case
initialization to lower in the main function.

It's a common pattern in our code to read paths from stdin,
separated either by newlines or NULs, and unquote as
necessary. In each of these five cases we use "nbuf" to
temporarily store the unquoted value. Let's give it the more
meaningful name "unquoted", which makes it easier to
understand the purpose of the variable.
While we're at it, let's also static-initialize all of our
strbufs. It's not wrong to call strbuf_init, but it
increases the cognitive load on the reader, who might wonder
"do we sometimes avoid initializing them? why?".

To name a commit, you can now use the :/!-<negative pattern> regex
style, and consequentially, say
$ git rev-parse HEAD^{/!-foo}
and it will return the hash of the first commit reachable from HEAD,
whose commit message does not contain "foo". This is the opposite of the
existing <rev>^{/<pattern>} syntax.
The specific use-case this is intended for is to perform an operation,
excluding the most-recent commits containing a particular marker. For
example, if you tend to make "work in progress" commits, with messages
beginning with "WIP", you work, then it could be useful to diff against
"the most recent commit which was not a WIP commit". That sort of thing
now possible, via commands such as:
$ git diff @^{/!-^WIP}
The leader '/!-', rather than simply '/!', to denote a negative match,
is chosen to leave room for additional modifiers in the future.

The git-over-rsync protocol is inefficient and broken, and
has been for a long time. It transfers way more objects than
it needs (grabbing all of the remote's "objects/",
regardless of which objects we need). It does its own ad-hoc
parsing of loose and packed refs from the remote, but
doesn't properly override packed refs with loose ones,
leading to garbage results (e.g., expecting the other side
to have an object pointed to by a stale packed-refs entry,
or complaining that the other side has two copies of the
refs[1]).
This latter breakage means that nobody could have
successfully pulled from a moderately active repository
since cd547b4 (fetch/push: readd rsync support, 2007-10-01).
We never made an official deprecation notice in the release
notes for git's rsync protocol, but the tutorial has marked
it as such since 914328a (Update tutorial., 2005-08-30).
And on the mailing list as far back as Oct 2005, we can find
Junio mentioning it as having "been deprecated for quite
some time."[2,3,4]. So it was old news then; cogito had
deprecated the transport in July of 2005[5] (though it did
come back briefly when Linus broke git-http-pull!).
Of course some people professed their love of rsync through
2006, but Linus clarified in his usual gentle manner[6]:
> Thanks! This is why I still use rsync, even though
> everybody and their mother tells me "Linus says rsync is
> deprecated."
No. You're using rsync because you're actively doing
something _wrong_.
The deprecation sentiment was reinforced in 2008, with a
mention that cloning via rsync is broken (with no fix)[7].
Even the commit porting rsync over to C from shell (cd547b4)
lists it as deprecated! So between the 10 years of informal
warnings, and the fact that it has been severely broken
since 2007, it's probably safe to simply remove it without
further deprecation warnings.

Once a lower-priority configuration file defines a clean or smudge
filter, there is no convenient way to override it to produce as-is
output. Even though the configuration mechanism implements "the
last one wins" semantics, you cannot set them to an empty string and
expect them to work, as apply_filter() would try to run the empty
string as an external command and fail. The conversion is not done,
but the function would still report a failure to convert.
Even though resetting the variable to "cat" (i.e. pass the data back
as-is and report success) is an obvious and a viable way to solve
this, it is wasteful to spawn an external process just as a
workaround.
Instead, teach apply_filter() to treat an empty string as a no-op
filter that always returns successfully its input as-is without
conversion.
