This is the "theoretically more correct" approach of simply
stepping back to the state before plumbing commands started paying
attention to "color.ui" configuration variable.
Let's run with this one.

Since 11b087adfd (ref-filter: consult want_color() before
emitting colors, 2017-07-13), we expect that setting
"color.ui" to "always" will enable color tag formats even
without a tty. As that commit was built on top of
136c8c8b8f (color: check color.ui in git_default_config(),
2017-07-13) from the same series, we didn't need to touch
tag's config parsing at all.
However, since we reverted 136c8c8b8f, we now need to
explicitly call git_color_default_config() to make this
work.
Let's do so, and also restore the test dropped in 0c88bf5050
(provide --color option for all ref-filter users,
2017-10-03). That commit swapped out our "color.ui=always"
test for "--color" in preparation for "always" going away.
But since it is here to stay, we should test both cases.
Note that for-each-ref also lost its color.ui support as
part of reverting 136c8c8b8f. But as a plumbing command, it
should _not_ respect the color.ui config. Since it also
gained a --color option in 0c88bf5050, that's the correct
way to ask it for color. We'll continue to test that, and
confirm that "color.ui" is not respected.

This reverts commit 136c8c8b8fa39f1315713248473dececf20f8fe7.
That commit was trying to address a bug caused by 4c7f1819b3
(make color.ui default to 'auto', 2013-06-10), in which
plumbing like diff-tree defaulted to "auto" color, but did
not respect a "color.ui" directive to disable it.
But it also meant that we started respecting "color.ui" set
to "always". This was a known problem, but 4c7f1819b3 argued
that nobody ought to be doing that. However, that turned out
to be wrong, and we got a number of bug reports related to
"add -p" regressing in v2.14.2.
Let's revert 136c8c8b8, fixing the regression to "add -p".
This leaves the problem from 4c7f1819b3 unfixed, but:
1. It's a pretty obscure problem in the first place. I
only noticed it while working on the color code, and we
haven't got a single bug report or complaint about it.
2. We can make a more moderate fix on top by respecting
"never" but not "always" for plumbing commands. This
is just the minimal fix to go back to the working state
we had before v2.14.2.
Note that this isn't a pure revert. We now have a test in
t3701 which shows off the "add -p" regression. This can be
flipped to success.

This reverts commit c5bdfe677cfab5b2e87771c35565d44d3198efda.
That commit was done primarily to prepare for the weakening
of "always" in 6be4595edb (color: make "always" the same as
"auto" in config, 2017-10-03). But since we've now reverted
6be4595edb, there's no need for us to remove "-c
color.ui=always" from the tests. And in fact it's a good
idea to restore these tests, to make sure that "always"
continues to work.

This reverts commit 6be4595edb8e5b616c6e8b9fbc78b0f831fa2a87.
That commit weakened the "always" setting of color config so
that it acted as "auto". This was meant to solve regressions
in v2.14.2 in which setting "color.ui=always" in the on-disk
config broke scripts like add--interactive, because the
plumbing diff commands began to generate color output.
This was due to 136c8c8b8f (color: check color.ui in
git_default_config(), 2017-07-13), which was in turn trying
to fix issues caused by 4c7f1819b3 (make color.ui default to
'auto', 2013-06-10). But in weakening "always", we created
even more problems, as people expect to be able to use "git
-c color.ui=always" to force color (especially because some
commands don't have their own --color flag). We can fix that
by special-casing the command-line "-c", but now things are
getting pretty confusing.
Instead of piling hacks upon hacks, let's start peeling off
the hacks. The first step is dropping the weakening of
"always", which this revert does.
Note that we could actually revert the whole series merged
in by da15b78e52642bd45fd5513ab0000fdf2e58a6f4. Most of that
series consists of preparations to the tests to handle the
weakening of "-c color.ui=always". But it's worth keeping
for a few reasons:
- there are some other preparatory cleanups, like
e433749d86 (test-terminal: set TERM=vt100, 2017-10-03)
- it adds "--color" options more consistently in
0c88bf5050 (provide --color option for all ref-filter
users, 2017-10-03)
- some of the cases dropping "-c" end up being more robust
and realistic tests, as in 01c94e9001 (t7508: use
test_terminal for color output, 2017-10-03)
- the preferred tool for overriding config is "--color",
and we should be modeling that consistently
We can individually revert the few commits necessary to
restore some useful tests (which will be done on top of this
patch).
Note that this isn't a pure revert; we'll keep the test
added in t3701, but mark it as failure for now.

The --color-moved code uses next_byte() to advance through
the blob contents. When the user has asked to ignore
whitespace changes, we try to collapse any whitespace change
down to a single space.
However, we enter the conditional block whenever we see the
IGNORE_WHITESPACE_CHANGE flag, even if the next byte isn't
whitespace.
This means that the combination of "--color-moved and
--ignore-space-change" was completely broken. Worse, because
we return from next_byte() without having advanced our
pointer, the function makes no forward progress in the
buffer and loops infinitely.
Fix this by entering the conditional only when we actually
see whitespace. We can apply this also to the
IGNORE_WHITESPACE change. That code path isn't buggy
(because it falls through to returning the next
non-whitespace byte), but it makes the logic more clear if
we only bother to look at whitespace flags after seeing that
the next byte is whitespace.

There are "git checkout [-p][<tree-ish>][--][<paths>...]" in the
SYNOPSIS section, and "git checkout [-p][<tree-ish>][--]<paths>..."
as the header for the section that explains the "check out paths
from index/tree-ish" mode. It is unclear if we require at least one
path, or it is entirely optional.
Actually, both are wrong. Without the "-p(atch)" option, you must
have <pathspec> (otherwise, with a commit that is a <tree-ish>, you
would be checking out that commit to build a new history on top of
it). With it, it is already clear that you are checking out paths,
it is optional. In other words, you cannot omit both.
The source of the confusion is that -p(atch) is described as if it
is just another "optional" part and its description is lumped
together with the non patch mode, even though the actual end user
experience is vastly different.
Let's split the entry into two, and describe the regular mode and
the patch mode separately. This allows us to make it clear that the
regular mode MUST be given at least one pathspec, that the patch
mode can be invoked with either '-p' or '--patch' but one of these
must be given, and that the pathspec is entirely optional in the
patch mode.
Also, revamp the explanation of "checkout paths" by removing
extraneous description at the beginning, that says "checking out
paths is not checking out a branch". Explaining what it is for and
when the user wants to use it upfront is the most direct way to help
the readers.

The write_entry() function switches on the mode of the entry
we're going to write out. The cases for S_IFLNK and S_IFREG
are lumped together. In earlier versions of the code, this
made some sense. They have a shared preamble (which reads
the blob content), a short type-specific body, and a shared
conclusion (which writes out the file contents; always for
S_IFREG and only sometimes for S_IFLNK).
But over time this has grown to make less sense. The preamble
now has conditional bits for each type, and the S_IFREG body
has grown a lot more complicated. It's hard to follow the
logic of which code is running for which mode.
Let's give each mode its own case arm. We will still share
the conclusion code, which means we now jump to it with a
goto. Ideally we'd pull that shared code into its own
function, but it touches so much internal state in the
write_entry() function that the end result is actually
harder to follow than the goto.
While we're here, we'll touch up a few bits of whitespace to
make the beginning and endings of the cases easier to read.

When retrying a delayed filter-process request, we don't
need to send the blob to the filter a second time. However,
we read it unconditionally into a buffer, only to later
throw away that buffer. We can make this more efficient by
skipping the read in the first place when it isn't
necessary.

When write_entry() retries a delayed filter request, we

set the pointer to NULL. But doing so means we leak the
contents we read earlier from read_blob_entry(). Let's make

A common mistake when writing binary search is to allow possible
integer overflow by using the simple average:
mid = (min + max) / 2;
Instead, use the overflow-safe version:
mid = min + (max - min) / 2;
This translation is safe since the operation occurs inside a loop
conditioned on "min < max". The included changes were found using
the following git grep:
git grep '/ *2;' '*.c'
Making this cleanup will prevent future review friction when a new
binary search is contructed based on existing code.

If our call to refs_read_raw_ref() fails, we check errno to
see if the ref is simply missing, or if we encountered a
more serious error. If it's just missing, then in "write"
mode (i.e., when RESOLVE_REFS_READING is not set), this is
perfectly fine.
However, checking for ENOENT isn't sufficient to catch all
missing-ref cases. In the filesystem backend, we may also
see EISDIR when we try to resolve "a" and "a/b" exists.
Likewise, we may see ENOTDIR if we try to resolve "a/b" and
"a" exists. In both of those cases, we know that our
resolved ref doesn't exist, but we return an error (rather
than reporting the refname and returning a null sha1).
This has been broken for a long time, but nobody really
noticed because the next step after resolving without the
READING flag is usually to lock the ref and write it. But in
both of those cases, the write will fail with the same
errno due to the directory/file conflict.
There are two cases where we can notice this, though:
1. If we try to write "a" and there's a leftover directory
already at "a", even though there is no ref "a/b". The
actual write is smart enough to move the empty "a" out
of the way.
This is reasonably rare, if only because the writing
code has to do an independent resolution before trying
its write (because the actual update_ref() code handles
this case fine). The notes-merge code does this, and
before the fix in the prior commit t3308 erroneously
expected this case to fail.
2. When resolving symbolic refs, we typically do not use
the READING flag because we want to resolve even
symrefs that point to unborn refs. Even if those unborn
refs could not actually be written because of d/f
conflicts with existing refs.
You can see this by asking "git symbolic-ref" to report
the target of a symref pointing past a d/f conflict.
We can fix the problem by recognizing the other "missing"
errnos and treating them like ENOENT. This should be safe to
do even for callers who are then going to actually write the
ref, because the actual writing process will fail if the d/f
conflict is a real one (and t1404 checks these cases).
Arguably this should be the responsibility of the
files-backend to normalize all "missing ref" errors into
ENOENT (since something like EISDIR may not be meaningful at
all to a database backend). However other callers of
refs_read_raw_ref() may actually care about the distinction;
putting this into resolve_ref() is the minimal fix for now.
The new tests in t1401 use git-symbolic-ref, which is the
most direct way to check the resolution by itself.
Interestingly we actually had a test that setup this case
already, but we only used it to verify that the funny state
could be overwritten, not that it could be resolved.
We also add a new test in t3200, as "branch -m" was the
original motivation for looking into this. What happens is
this:
0. HEAD is pointing to branch "a"
1. The user asks to rename "a" to "a/b".
2. We create "a/b" and delete "a".
3. We then try to update any worktree HEADs that point to
the renamed ref (including the main repo HEAD). To do
that, we have to resolve each HEAD. But now our HEAD is
pointing at "a", and we get EISDIR due to the loose
"a/b". As a result, we think there is no HEAD, and we
do not update it. It now points to the bogus "a".
Interestingly this case used to work, but only accidentally.
Before 31824d180d (branch: fix branch renaming not updating
HEADs correctly, 2017-08-24), we'd update any HEAD which we
couldn't resolve. That was wrong, but it papered over the
fact that we were incorrectly failing to resolve HEAD.
So while the bug demonstrated by the git-symbolic-ref is
quite old, the regression to "branch -m" is recent.

A test in t3308 wants to make sure that we don't
accidentally merge into "refs/notes/dir" when it exists as a
directory, so it does:
mkdir .git/refs/notes/dir
git -c core.notesRef=refs/notes/dir merge ...
and expects the second command to fail. But that
understimates the refs code, which is smart enough to remove
useless directories in the refs hierarchy. The test
succeeded only because of a bug which prevented resolving
refs/notes/dir for writing, even though an actual ref update
would succeed.
In preparation for fixing that bug, let's switch to creating
a real ref in refs/notes/dir, which is a more realistic
situation.
