Read-only operations such as "git status" that internally refreshes
the index write out the refreshed index to the disk to optimize
future accesses to the working tree, but this could race with a
"read-write" operation that modify the index while it is running.
Detect such a race and avoid overwriting the index.
Duy raised a good point that we may need to do the same for the
normal writeout codepath, not just the "opportunistic" update
codepath. While that is true, nobody sane would be running two
simultaneous operations that are clearly write-oriented competing
with each other against the same index file. So in that sense that
can be done as a less urgent follow-up for this topic.

Instead of running N pair-wise diff-trees when inspecting a

read_ref_at has its own parsing of the reflog file for no really good reason
so lets change this to use the existing reflog iterators. This removes one
instance where we manually unmarshall the reflog file format.
Remove the now redundant ref_msg function.
Log messages for errors are changed slightly. We no longer print the file
name for the reflog, instead we refer to it as 'Log for ref <refname>'.
This might be a minor useability regression, but I don't really think so, since
experienced users would know where the log is anyway and inexperienced users
would not know what to do about/how to repair 'Log ... has gap ...' anyway.
Adapt the t1400 test to handle the change in log messages.

When you try to commit with unmerged entries, you get an
error like:
$ git commit
error: 'commit' is not possible because you have unmerged files.
The quotes around "commit" are clunky; the user doesn't care
that this message is a template with the command-name filled
in. Saying:
error: commit is not possible because you have unmerged files
is easier to read. As this code is called from other places,
we may also end up with:
$ git merge
error: merge is not possible because you have unmerged files
$ git cherry-pick foo
error: cherry-pick is not possible because you have unmerged files
$ git revert foo
error: revert is not possible because you have unmerged files
All of which look better without the quotes. This also
happens to match the behavior of "git pull", which generates
a similar message (but does not share code, as it is a shell
script).

Discard the unnecessary 'nr_spaces' variable, remove 'strlen()' and

Slightly more rare occurrences of 'text \ ' with a backslash
in between spaces are handled correctly. Namely, the code in
7e2e4b37 (dir: ignore trailing spaces in exclude patterns, 2014-02-09)

Whenever the hash table becomes too small then its size is increased,
the original part (and the added space) is zerod out using memset(),
and the table is rebuilt from scratch.
Simplify this proceess by returning the old memory using free() and
allocating the new buffer using xcalloc(), which already clears the
buffer for us. That way we avoid copying the old hash table contents
needlessly inside xrealloc().
While at it, use the first array member with sizeof instead of a
specific type. The old code used uint32_t and int, while index is
actually an array of int32_t. Their sizes are the same basically
everywhere, so it's not actually a problem, but the new code is
cleaner and doesn't have to be touched should the type be changed.

Diagnostic messages received on the sideband #2 from the server side
are sent to the standard error with ANSI terminal control sequence
"\033[K" that erases to the end of line appended at the end of each
line.
However, some programs (e.g. GitExtensions for Windows) read and
interpret and/or show the message without understanding the terminal
control sequences, resulting them to be shown to their end users.
To help these programs, squelch the control sequence when the
standard error stream is not being sent to a tty.
NOTE: I considered to cover the case that a pager has already been
started. But decided that is probably not worth worrying about here,
though, as we shouldn't be using a pager for commands that do network

is probably a sane thing to do).

The changes to make detection of endianness more portable had a bug
that breaks on (at least) Solaris x86.
The bug appears to be a simple copy/paste typo. It checks for
_BIG_ENDIAN and not _LITTLE_ENDIAN for both the case where we would
decide the system is big endian and little endian. Instead, the
second test should be for _LITTLE_ENDIAN and not _BIG_ENDIAN.
Two fixes were possible:
1. Change the negation order of the conditions in the second test.
2. Reverse the order of the conditions in the second test.
Use the second option so that the condition we expect is always a
positive check.

Note that we have to munge the test in a few ways while
moving it:
1. We drop the `test -z "$GIT_TEST_HTTPD"` check; this is
too simplistic since 83d842d, and we should let
lib-httpd.sh handle it.
2. We have to port over some of the old setup from t5538.

These were originally removed by 0232852 (t5537: move
http tests out to t5539, 2014-02-13). However, they were
accidentally re-added in 1ddb4d7 (Merge branch
'nd/upload-pack-shallow', 2014-03-21).
This looks like an error in manual conflict resolution.
Here's what happened:
1. v1.9.0 shipped with the http tests in t5537.
2. We realized that this caused problems, and built
0232852 on top to move the tests to their own file.
This fix made it into v1.9.1.
3. We later had another fix in nd/upload-pack-shallow that
also touched t5537. It was built directly on v1.9.0.
When we merged nd/upload-pack-shallow to master, we got a
conflict; it was built on a version with the http tests, but
we had since removed them. The correct resolution was to
drop the http tests and keep the new ones, but instead we
kept everything.

of time was spent deleting those refs since for each deleted ref,
repack_without_refs() was called to rewrite packed-refs without just
that deleted ref.
To avoid this, call repack_without_refs() first to repack without all
the refs that will be deleted, before calling delete_ref() to delete
each one completely. The call to repack_without_ref() in delete_ref()
then becomes a no-op, since packed-refs already won't contain any of
