Rename 'refinfo' to 'ref_array_item' as a preparatory step for
introduction of new structures in the forthcoming patch.
Re-order the fields in 'ref_array_item' so that refname can be
eventually converted to a FLEX_ARRAY.

Extract two helper functions out of grab_single_ref(). Firstly,
new_refinfo() which is used to allocate memory for a new refinfo
structure and copy the objectname, refname and flag to it.
Secondly, match_name_as_path() which when given an array of patterns
and the refname checks if the refname matches any of the patterns
given while the pattern is a pathname, also supports wildcard
characters.
This is a preperatory patch for restructuring 'for-each-ref' and
eventually moving most of it to 'ref-filter' to provide the
functionality to similar commands via public API's.

Recent "git prune" traverses young unreachable objects to safekeep
old objects in the reachability chain from them, which sometimes
caused error messages that are unnecessarily alarming.

When we are traversing commit parents along the
UNINTERESTING side of a revision walk, we do not care if
the parent turns out to be missing. That lets us limit
traversals using unreachable and possibly incomplete
sections of history. However, we do still print error
messages about the missing commits; this patch suppresses
the error, as well.

We set revs->ignore_missing_links to instruct the
revision-walking machinery that we know the history graph
may be incomplete. For example, we use it when walking
unreachable but recent objects; we want to add what we can,
but it's OK if the history is incomplete.
However, we still print error messages for the missing
objects, which can be confusing. This is not an error, but
just a normal situation when transitioning from a repository
last pruned by an older git (which can leave broken segments
of history) to a more recent one (where we try to preserve
whole reachable segments).

When we call parse_commit, it will complain to stderr if the
object does not exist or cannot be read. This means that we
may produce useless error messages if this situation is
expected (e.g., because the object is marked UNINTERESTING,
or because revs->ignore_missing_links is set).
We can fix this by adding a new "parse_X_gently" form that
takes a flag to suppress the messages. The existing
"parse_X" form is already gentle in the sense that it
returns an error rather than dying, and we could in theory
just add a "quiet" flag to it (with existing callers passing
"0"). But doing it this way means we do not have to disturb
existing callers.
Note also that the new flag is "quiet_on_missing", and not
just "quiet". We could add a flag to suppress _all_ errors,
but besides being a more invasive change (we would have to
pass the flag down to sub-functions, too), there is a good
reason not to: we would never want to use it. Missing a
linked object is expected in some circumstances, but it is
never expected to have a malformed commit, or to get a tree
when we wanted a commit. We should always complain about
these corruptions.

a8c9bef (pull: improve advice for unconfigured error case, 2009-10-05)
fully established the current advices given by git-pull for the
different cases where git-fetch will not have anything marked for merge:
1. We fetched from a specific remote, and a refspec was given, but it
ended up not fetching anything. This is usually because the user
provided a wildcard refspec which had no matches on the remote end.
2. We fetched from a non-default remote, but didn't specify a branch to
merge. We can't use the configured one because it applies to the
default remote, and thus the user must specify the branches to merge.
3. We fetched from the branch's or repo's default remote, but:
a. We are not on a branch, so there will never be a configured branch
to merge with.
b. We are on a branch, but there is no configured branch to merge
with.
4. We fetched from the branch's or repo's default remote, but the
configured branch to merge didn't get fetched (either it doesn't
exist, or wasn't part of the configured fetch refspec)
Implement tests for the above 5 cases to ensure that the correct code
paths are triggered for each of these cases.

Many tests in t5520 used the following to test the contents of files:
test `cat file` = expected
or
test $(cat file) = expected
These 2 forms, however, will be affected by field splitting and,
depending on the value of $IFS, may be split into multiple arguments,
making the test fail in mysterious ways.
Replace the above 2 forms with:
test "$(cat file)" = expected
as quoting the command substitution will prevent field splitting.

It's better to start the man page with a description of what
submodules actually are, instead of saying what they are not.
Reorder the paragraphs such that
- the first short paragraph introduces the submodule concept,
- the second paragraph highlights the usage of the submodule command,
- the third paragraph giving background information, and finally
- the fourth paragraph discusing alternatives such as subtrees and
remotes, which we don't want to be confused with.
This ordering deepens the knowledge on submodules with each paragraph.
First the basic questions like "How/what" will be answered, while the
underlying concepts will be taught at a later time.
Making sure it is not confused with subtrees and remotes is not really
enhancing knowledge of submodules itself, but rather painting the big
picture of git concepts, so you could also argue to have it as the second
paragraph. Personally I think this may confuse readers, specially
newcomers though.
Additionally to reordering the paragraphs, they have been slightly
reworded.

If we try to mmap a directory, we'll get ENODEV. This
translates to "no such device" for the user, which is not
very helpful. Since we've just fstat()'d the file, we can
easily check whether the problem was a directory to give a

The config-writing code uses xmmap to map the existing
config file, which will die if the map fails. This has two
downsides:
1. The error message is not very helpful, as it lacks any
context about the file we are mapping:
$ mkdir foo
$ git config --file=foo some.key value
fatal: Out of memory? mmap failed: No such device
2. We normally do not die in this code path; instead, we'd
rather report the error and return an appropriate exit
status (which is part of the public interface
documented in git-config.1).
This patch introduces a "gentle" form of xmmap which lets us
produce our own error message. We do not want to use mmap
directly, because we would like to use the other
compatibility elements of xmmap (e.g., handling 0-length
maps portably).
The end result is:
$ git.compile config --file=foo some.key value
error: unable to mmap 'foo': No such device
$ echo $?

We mmap the existing config file, but fail to unmap it if we

Once upon a time, git's in-memory representation of a cache
entry actually pointed to the mmap'd on-disk data. So in
520fc24 (Allow writing to the private index file mapping.,
2005-04-26), we specified PROT_WRITE so that we could tweak
the entries while we run (in our own MAP_PRIVATE copy-on-write
version, of course).
Later, 7a51ed6 (Make on-disk index representation separate
from in-core one, 2008-01-14) stopped doing this; we copy
the data into our in-core representation, and then drop the
mmap immediately. We can therefore drop the PROT_WRITE flag.
It's probably not hurting anything as it is, but it's
potentially confusing.
Note that we could also mark the mapping as "const" to
verify that we never write to it. However, we don't
typically do that for our other maps, as it then requires
casting to munmap() it.

Its return value wasn't conveying any extra information, but it made
the reader wonder whether the ref_lock that it returned might be

"color.diff.plain" was a misnomer; give it 'color.diff.context' as
a more logical synonym.
* jk/color-diff-plain-is-context:
diff.h: rename DIFF_PLAIN color slot to DIFF_CONTEXT
diff: accept color.diff.context as a synonym for "plain"

The latter is a much more descriptive name (and we support
"color.diff.context" now). This also updates the name of any
local variables which were used to store the color.

The term "plain" is a bit ambiguous; let's allow the more
specific "context", but keep "plain" around for
compatibility.

Code clean-up.

clone: reorder --dissociate and --reference options
clone: use OPT_STRING_LIST for --reference

These options are intimately related, so it makes sense to
list them nearby in the "-h" output (they are already
adjacent in the manpage).

Not only does this save us having to implement a custom
callback, but it handles "--no-reference" in the usual way
(to clear the list).
The generic callback does copy the string, which we don't
technically need, but that should not hurt anything.

Allow whitespace breakages in deleted and context lines to be also
painted in the output.

Traditionally, we only cared about whitespace breakages introduced
in new lines. Some people want to paint whitespace breakages on old
lines, too. When they see a whitespace breakage on a new line, they
can spot the same kind of whitespace breakage on the corresponding
old line and want to say "Ah, those breakages are there but they
were inherited from the original, so let's not touch them for now."
Introduce `--ws-error-highlight=<kind>` option, that lets them pass
a comma separated list of `old`, `new`, and `context` to specify
what lines to highlight whitespace errors on.

Traditionally, we only had emit_add_line() helper, which knows how
to find and paint whitespace breakages on the given line, because we
only care about whitespace breakages introduced in new lines. The
context lines and old (i.e. deleted) lines are emitted with a
simpler emit_line_0() that paints the entire line in plain or old
colors.
Identify callers of emit_line_0() that show deleted lines and
context lines, have them call new helpers, emit_del_line() and
emit_context_line(), so that we can later tweak what is done to
these two classes of lines.

The last two tests in the script were to
- set up color.diff.* slots
- set up an expectation for a single test
- run that test and check the result
but split in a wrong way. It did the first two in the first test
and the third one in the second test. The latter two belong to each
other. This matters when you plan to add more of these tests that
share the common coloring.
While at it, make sure we use a color different from old, which is
also red.

Move the preparatory steps that create the expected output inside
the test bodies, remove unnecessary blank lines before and after the
test bodies, and drop SP between redirection operator and its target.
