@gitster gitster diff --stat: do not count "unmerged" entries
Even though we show a separate *UNMERGED* entry in the patch and
diffstat output (or in the --raw format, for that matter) in
addition to and separately from the diff against the specified stage
(defaulting to #2) for unmerged paths, they should not be counted in
the total number of files affected---that would lead to counting the
same path twice.

The separation done by the previous step makes this fix simple and
straightforward.  Among the filepairs in diff_queue, paths that
weren't modified, and the extra "unmerged" entries do not count as
total number of files.

@pclouds pclouds cache-tree: fix writing cache-tree when CE_REMOVE is present
entry_count is used in update_one() for two purposes:

1. to skip through the number of processed entries in in-memory index
2. to record the number of entries this cache-tree covers on disk

Unfortunately when CE_REMOVE is present these numbers are not the same
because CE_REMOVE entries are automatically removed before writing to
disk but entry_count is not adjusted and still counts CE_REMOVE
entries.

Separate the two use cases into two different variables. #1 is taken
care by the new field count in struct cache_tree_sub and entry_count
is prepared for #2.

@jherland jherland checkout: Use remote refspecs when DWIMming tracking branches
The DWIM mode of checkout allows you to run "git checkout foo" when there
is no existing local ref or path called "foo", and there is exactly _one_
remote with a remote-tracking branch called "foo". Git will automatically
create a new local branch called "foo" using the remote-tracking "foo" as
its starting point and configured upstream.

For example, consider the following unconventional (but perfectly valid)
remote setup:

	[remote "origin"]
		fetch = refs/heads/*:refs/remotes/origin/*
	[remote "frotz"]
		fetch = refs/heads/*:refs/remotes/frotz/nitfol/*

Case 1: Assume both "origin" and "frotz" have remote-tracking branches called
"foo", at "refs/remotes/origin/foo" and "refs/remotes/frotz/nitfol/foo"
respectively. In this case "git checkout foo" should fail, because there is
more than one remote with a "foo" branch.

Case 2: Assume only "frotz" have a remote-tracking branch called "foo". In
this case "git checkout foo" should succeed, and create a local branch "foo"
from "refs/remotes/frotz/nitfol/foo", using remote branch "foo" from "frotz"
as its upstream.

The current code hardcodes the assumption that all remote-tracking branches
must match the "refs/remotes/$remote/*" pattern (which is true for remotes
with "conventional" refspecs, but not true for the "frotz" remote above).
When running "git checkout foo", the current code looks for exactly one ref
matching "refs/remotes/*/foo", hence in the above example, it fails to find
"refs/remotes/frotz/nitfol/foo", which causes it to fail both case #1 and #2.

The better way to handle the above example is to actually study the fetch
refspecs to deduce the candidate remote-tracking branches for "foo"; i.e.
assume "foo" is a remote branch being fetched, and then map "refs/heads/foo"
through the refspecs in order to get the corresponding remote-tracking
branches "refs/remotes/origin/foo" and "refs/remotes/frotz/nitfol/foo".
Finally we check which of these happens to exist in the local repo, and
if there is exactly one, we have an unambiguous match for "git checkout foo",
and may proceed.

This fixes most of the failing tests introduced in the previous patch.

@pclouds pclouds parse_pathspec: add PATHSPEC_PREFER_{CWD,FULL} flags
We have two ways of dealing with empty pathspec:

1. limit it to current prefix
2. match the entire working directory

Some commands go with #1, some #2. get_pathspec() and parse_pathspec()
only support #1. Make parse_pathspec() reject empty pathspec by
default. #1 and #2 can be specified via new flags. This makes it more
expressive about default behavior at command level.

@jherland jherland t3200: Add test demonstrating minor regression in 41c21f2
In 41c21f2 (branch.c: Validate tracking branches with refspecs instead of
refs/remotes/*), we changed the rules for what is considered a valid tracking
branch (a.k.a. upstream branch). We now use the configured remotes and their
refspecs to determine whether a proposed tracking branch is in fact within
the domain of a remote, and we then use that information to deduce the
upstream configuration (branch.<name>.remote and branch.<name>.merge).

However, with that change, we also check that - in addition to a matching
refspec - the result of mapping the tracking branch through that refspec
(i.e. the corresponding ref name in the remote repo) happens to start with
"refs/heads/". In other words, we require that a tracking branch refers to
a _branch_ in the remote repo.

Now, consider that you are e.g. setting up an automated building/testing
infrastructure for a group of similar "source" repositories. The build/test
infrastructure consists of a central scheduler, and a number of build/test
"slave" machines that perform the actual build/test work. The scheduler
monitors the group of similar repos for changes (e.g. with a periodic
"git fetch"), and triggers builds/tests to be run on one or more slaves.
Graphically the changes flow between the repos like this:

  Source #1 -------v          ----> Slave #1
                             /
  Source #2 -----> Scheduler -----> Slave #2
                             \
  Source #3 -------^          ----> Slave #3

        ...                           ...

The scheduler maintains a single Git repo with each of the source repos set
up as distinct remotes. The slaves also need access to all the changes from
all of the source repos, so they pull from the scheduler repo, but using the
following custom refspec:

  remote.origin.fetch = "+refs/remotes/*:refs/remotes/*"

This makes all of the scheduler's remote-tracking branches automatically
available as identical remote-tracking branches in each of the slaves.

Now, consider what happens if a slave tries to create a local branch with
one of the remote-tracking branches as upstream:

  git branch local_branch --track refs/remotes/source-1/some_branch

Git now looks at the configured remotes (in this case there is only "origin",
pointing to the scheduler's repo) and sees refs/remotes/source-1/some_branch
matching origin's refspec. Mapping through that refspec we find that the
corresponding remote ref name is "refs/remotes/source-1/some_branch".
However, since this remote ref name does not start with "refs/heads/", we
discard it as a suitable upstream, and the whole command fails.

This patch adds a testcase demonstrating this failure by creating two
source repos ("a" and "b") that are forwarded through a scheduler ("c")
to a slave repo ("d"), that then tries create a local branch with an
upstream. See the next patch in this series for the exciting conclusion
to this story...

@mnaoumov mnaoumov sideband.c: do not use ANSI control sequence on non-terminal
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
communications (and if we do, omitting the magic line-clearing signal
is probably a sane thing to do).

@pclouds pclouds utf8.c: fix strbuf_utf8_replace() consuming data beyond input string
The main loop in strbuf_utf8_replace() could summed up as:

  while ('src' is still valid) {
    1) advance 'src' to copy ANSI escape sequences
    2) advance 'src' to copy/replace visible characters
  }

The problem is after #1, 'src' may have reached the end of the string
(so 'src' points to NUL) and #2 will continue to copy that NUL as if
it's a normal character. Because the output is stored in a strbuf,
this NUL accounted in the 'len' field as well. Check after #1 and
break the loop if necessary.

The test does not look obvious, but the combination of %>>() should
make a call trace like this

  show_log()
  pretty_print_commit()
  format_commit_message()
  strbuf_expand()
  format_commit_item()
  format_and_pad_commit()
  strbuf_utf8_replace()

where %C(auto)%d would insert a color reset escape sequence in the end
of the string given to strbuf_utf8_replace() and show_log() uses
fwrite() to send everything to stdout (including the incorrect NUL
inserted by strbuf_utf8_replace)

@dscho dscho Add regression tests for stricter tag fsck'ing
The intent of the new test case is to catch general breakages in
the fsck_tag() function, not so much to test it extensively, trying to
strike the proper balance between thoroughness and speed.

While it *would* have been nice to test the code path where fsck_object()
encounters an invalid tag object, this is not possible using git fsck: tag
objects are parsed already before fsck'ing (and the parser already fails
upon such objects).

Even worse: we would not even be able write out invalid tag objects
because git hash-object parses those objects, too, unless we resorted to
really ugly hacks such as using something like this in the unit tests
(essentially depending on Perl *and* Compress::Zlib):

	hash_invalid_object () {
		contents="$(printf '%s %d\0%s' "$1" ${#2} "$2")" &&
		sha1=$(echo "$contents" | test-sha1) &&
		suffix=${sha1#??} &&
		mkdir -p .git/objects/${sha1%$suffix} &&
		echo "$contents" |
		perl -MCompress::Zlib -e 'undef $/; print compress(<>)' \
			> .git/objects/${sha1%$suffix}/$suffix &&
		echo $sha1
	}

@gitster gitster diff-format doc: a score can follow M for rewrite
b6d8f30 (diff-raw format update take #2., 2005-05-23) started
documenting the diff format, and it said

 ...
 (8) sha1 for "dst"; 0{40} if creation, unmerged or "look at work tree".
 (9) status, followed by similarlity index number only for C and R.
 (10) a tab or a NUL when '-z' option is used.
 ...

because C and R _were_ the only ones that came with a number back
then.  This was corrected by ddafa7e (diff-helper: Fix R/C score
parsing under -z flag., 2005-05-29) and we started saying "score"
instead of "similarlity index" (because we can have other kind of
score there), and stopped saying "only for C and R" (because Git is
an ever evolving system).  Later f345b0a (Add -B flag to diff-*
brothers., 2005-05-30) introduced a new concept, "dissimilarity"
score; it did not have to fix any documentation.

The current text that says only C and R can have scores came
independently from a5a323f (Add reference for status letters in
documentation., 2008-11-02) and it was wrong from the day one.

@gitster gitster merge: handle FETCH_HEAD internally
The collect_parents() function now is responsible for

 1. parsing the commits given on the command line into a list of
    commits to be merged;

 2. filtering these parents into independent ones; and

 3. optionally calling fmt_merge_msg() via prepare_merge_message()
    to prepare an auto-generated merge log message, using fake
    contents that FETCH_HEAD would have had if these commits were
    fetched from the current repository with "git pull . $args..."

Make "git merge FETCH_HEAD" to be the same as the traditional

    git merge "$(git fmt-merge-msg <.git/FETCH_HEAD)" $commits

invocation of the command in "git pull", where $commits are the ones
that appear in FETCH_HEAD that are not marked as not-for-merge, by
making it do a bit more, specifically:

 - noticing "FETCH_HEAD" is the only "commit" on the command line
   and picking the commits that are not marked as not-for-merge as
   the list of commits to be merged (substitute for step #1 above);

 - letting the resulting list fed to step #2 above;

 - doing the step #3 above, using the contents of the FETCH_HEAD
   instead of fake contents crafted from the list of commits parsed
   in the step #1 above.

Note that this changes the semantics.  "git merge FETCH_HEAD" has
always behaved as if the first commit in the FETCH_HEAD file were
directly specified on the command line, creating a two-way merge
whose auto-generated merge log said "merge commit xyz".  With this
change, if the previous fetch was to grab multiple branches (e.g.
"git fetch $there topic-a topic-b"), the new world order is to
create an octopus, behaving as if "git pull $there topic-a topic-b"
were run.  This is a deliberate change to make that happen, and
can be seen in the changes to t3033 tests.

@gitster gitster rerere: fix an off-by-one non-bug
When ac49f5c (rerere "remaining", 2011-02-16) split out a new
helper function check_one_conflict() out of find_conflict()
function, so that the latter will use the returned value from the
new helper to update the loop control variable that is an index into
active_cache[], the new variable incremented the index by one too
many when it found a path with only stage #1 entry at the very end
of active_cache[].

This "strange" return value does not have any effect on the loop
control of two callers of this function, as they all notice that
active_nr+2 is larger than active_nr just like active_nr+1 is, but
nevertheless it puzzles the readers when they are trying to figure
out what the function is trying to do.

In fact, there is no need to do an early return.  The code that
follows after skipping the stage #1 entry is fully prepared to
handle a case where the entry is at the very end of active_cache[].

Help future readers from unnecessary confusion by dropping an early
return.  We skip the stage #1 entry, and if there are stage #2 and
stage #3 entries for the same path, we diagnose the path as
THREE_STAGED (otherwise we say PUNTED), and then we skip all entries
for the same path.
