The improved ARRAY_SIZE macro uses BARF_UNLESS_AN_ARRAY which expands
to a valid check for recent gcc versions and to 0 for older gcc
versions but is not defined on non-gcc builds.
Non-gcc builds need this macro to expand to 0 as well. The current outer
test (defined(__GNUC__) && (__GNUC__ >= 3)) is a strictly weaker
condition than the inner test (GIT_GNUC_PREREQ(3, 1)) so we can omit the
outer test and cause the BARF_UNLESS_AN_ARRAY macro to be defined
correctly on non-gcc builds as well as gcc builds with older versions.

This reverts commit d95d728aba06a34394d15466045cbdabdada58a2.
It turns out that many other commands that need to interact with the
result of running diff-files and diff-index, e.g. "git apply", "git
rm", etc., need to be adjusted to the new world order it brings in.
For example, it would break this sequence to correct a whitespace
breakage in the parts you changed:
git add -N file
git diff --cached file | git apply --cached --whitespace=fix
git checkout file
In the old world order, "diff" showed a patch to modify an existing
empty file by adding its full contents, and "apply" updated the
index by modifying the existing empty blob (which is what an
Intent-to-Add entry records in the index) with that patch.
In the new world order, "diff" shows a patch to create a new file
with its full contents, but because "apply" thinks that the i-t-a
entry already exists in the index, it refused to accept a creation.
Adjusting "apply" to this new world order is easy, but we need to
assess the extent of the damage to the rest of the system the new
world order brought in before going forward and adjust them all,
after which we can resurrect the commit being reverted here.

This reverts commit ed178ef13a26136d86ff4e33bb7b1afb5033f908.
That commit was an attempt to improve the safety of applying
a stash, because the application process may create
conflicted index entries, after which it is hard to restore
the original index state.
Unfortunately, this hurts some common workflows around "git
stash -k", like:
git add -p ;# (1) stage set of proposed changes
git stash -k ;# (2) get rid of everything else
make test ;# (3) make sure proposal is reasonable
git stash apply ;# (4) restore original working tree
If you "git commit" between steps (3) and (4), then this
just works. However, if these steps are part of a pre-commit
hook, you don't have that opportunity (you have to restore
the original state regardless of whether the tests passed or
failed).
It's possible that we could provide better tools for this
sort of workflow. In particular, even before ed178ef, it
could fail with a conflict if there were conflicting hunks
in the working tree and index (since the "stash -k" puts the
index version into the working tree, and we then attempt to
apply the differences between HEAD and the old working tree
on top of that). But the fact remains that people have been
using it happily for a while, and the safety provided by
ed178ef is simply not that great. Let's revert it for now.
In the long run, people can work on improving stash for this
sort of workflow, but the safety tradeoff is not worth it in
the meantime.

The output of "pmset -g batt" changed at some point from "Currently
drawing from 'AC Power'" to the slightly different "Now drawing from
'AC Power'". Starting the match from "drawing" makes the check work
in both old and new versions of OS X.

The --changes-block-size handling was intended to help when
a user has a limited "maxscanrows" (see "p4 group"). It used
"p4 changes -m $maxchanges" to limit the number of results.
Unfortunately, it turns out that the "maxscanrows" and "maxresults"
limits are actually applied *before* the "-m maxchanges" parameter
is considered (experimentally).
Fix the block-size handling so that it gets blocks of changes
limited by revision number ($Start..$Start+$N, etc). This limits
the number of results early enough that both sets of tests pass.
Note that many other Perforce operations can fail for the same
reason (p4 print, p4 files, etc) and it's probably not possible
to workaround this. In the real world, this is probably not
usually a problem.

Change the --changes-block-size git-p4 test to use an account with
limited "maxresults" and "maxscanrows" values.
These conditions are applied in the server *before* the "-m maxchanges"
parameter to "p4 changes" is applied, and so the strategy that git-p4
uses for limiting the number of changes does not work. As a result,
the tests all fail.
Note that "maxscanrows" is set quite high, as it appears to not only
limit results from "p4 changes", but *also* limits results from
"p4 print". Files that have more than "maxscanrows" changes seem
(experimentally) to be impossible to print. There's no good way to
work around this.

"git commit --cleanup=scissors" was not careful enough to protect
against getting fooled by a line that looked like scissors.

The diff and submodule shortlog appended to the commit message template
by 'git commit --verbose' are not stripped when the commit message
contains an indented scissors line.
When cleaning up a commit message with 'git commit --verbose' or
'--cleanup=scissors' the code is careful and triggers only on a pure
scissors line, i.e. a line containing nothing but a comment character, a
space, and the scissors cut. This is good, because people can embed
scissors lines in the commit message while using 'git commit --verbose',
and the text they write after their indented scissors line doesn't get
deleted.
While doing so, however, the cleanup function only looks at the first
line matching the scissors pattern and if it doesn't start at the
beginning of the line, then the function just returns without performing
any cleanup. This is wrong, because a "real" scissors line added by
'git commit --verbose' might follow, and in that case the diff and
submodule shortlog get included in the commit message.
Fix this by changing the scissors pattern to match only at the beginning
of the line, yet be careful to catch scissors on the first line as well.

Since 45e8a74 (has_sha1_file: re-check pack directory before
giving up, 2013-08-30), we spend extra effort for
has_sha1_file to give the right answer when somebody else is
repacking. Usually this effort does not matter, because
after finding that the object does not exist, the next step
is usually to die().
However, some code paths make a large number of
has_sha1_file checks which are _not_ expected to return 1.
The collision test in index-pack.c is such a case. On a
local system, this can cause a performance slowdown of
around 5%. But on a system with high-latency system calls
(like NFS), it can be much worse.
This patch introduces a "quick" flag to has_sha1_file which
callers can use when they would prefer high performance at
the cost of false negatives during repacks. There may be
other code paths that can use this, but the index-pack one
is the most obviously critical, so we'll start with
switching that one.

tcsh users who happen to have 'set noclobber' elsewhere in their
~/.tcshrc or ~/.cshrc startup files get a 'File exist' error, and
the tcsh completion file doesn't get generated/updated.
Adding a `!` in the redirect works correctly for both clobber (default)
and 'set noclobber' users.

NULL_SHA1 is used to indicate an "invalid object name" throughout our
code (and the code of other git implementations), so it is vastly more
likely that an on-disk reference was set to this value due to a
software bug than that NULL_SHA1 is the legitimate SHA-1 of an actual
object. Therefore, if a loose reference has the value NULL_SHA1,
consider it to be broken.

If there is a loose reference file with invalid contents, "git
for-each-ref" incorrectly reports the problem as being a missing
object with name NULL_SHA1:
$ echo '12345678' >.git/refs/heads/nonsense
$ git for-each-ref
fatal: missing object 0000000000000000000000000000000000000000 for refs/heads/nonsense
With an explicit "--format" string, it can even report that the
reference validly points at NULL_SHA1:
$ git for-each-ref --format='%(objectname) %(refname)'
0000000000000000000000000000000000000000 refs/heads/nonsense
$ echo $?
0
This has been broken since
b7dd2d2 for-each-ref: Do not lookup objects when they will not be used (2009-05-27)
, which changed for-each-ref from using for_each_ref() to using
git_for_each_rawref() in order to avoid looking up the referred-to
objects unnecessarily. (When "git for-each-ref" is given a "--format"
string that doesn't include information about the pointed-to object,
it does not look up the object at all, which makes it considerably
faster. Iterating with DO_FOR_EACH_INCLUDE_BROKEN is essential to this
optimization because otherwise for_each_ref() would itself need to
check whether the object exists as part of its brokenness test.)
But for_each_rawref() includes broken references in the iteration, and
"git for-each-ref" doesn't itself reject references with REF_ISBROKEN.
The result is that broken references are processed *as if* they had
the value NULL_SHA1, which is the value stored in entries for broken
references.
Change "git for-each-ref" to emit warnings for references that are
REF_ISBROKEN but to otherwise skip them.

Add tests that for-each-ref correctly reports broken loose reference
files and references that point at missing objects. In fact, two of
these tests fail, because (1) NULL_SHA1 is not recognized as an
invalid reference value, and (2) for-each-ref doesn't respect
REF_ISBROKEN. Fixes to come.
Note that when for-each-ref is run with a --format option that doesn't
require the object to be looked up, then we should still notice if a
loose reference file is corrupt or contains NULL_SHA1, but we don't
notice if it points at a missing object because we don't do an object
lookup. This is OK.
