Merge branch 'en/rename-directory-detection' into next
Rename detection logic in "diff" family that is used in "merge" has
learned to guess when all of x/a, x/b and x/c have moved to z/a,
z/b and z/c, it is likely that x/d added in the meantime would also
want to move to z/d by taking the hint that the entire directory
'x' moved to 'z'. A bug causing dirty files involved in a rename
to be overwritten during merge has also been fixed as part of this

This adds xfuncname and word_regex patterns for golang, a quite
popular programming language. It also includes test cases for the
xfuncname regex (t4018) and updated documentation.
The xfuncname regex finds functions, structs and interfaces. Although
the Go language prohibits the opening brace from being on its own
line, the regex does not makes it mandatory, to be able to match
`func` statements like this:
func foo(bar int,
baz int) {
}
This is covered by the test case t4018/golang-long-func.
The word_regex pattern finds identifiers, integers, floats, complex
numbers and operators, according to the go specification.

commit: run git gc --auto just before the post-commit hook
Change the behavior of git-commit back to what it was back in d4bb43ee27 ("Invoke "git gc --auto" from commit, merge, am and
rebase.", 2007-09-05) when it was git-commit.sh.
Shortly afterwards in f5bbc3225c ("Port git commit to C.", 2007-11-08)
when it was ported to C, the "git gc --auto" invocation went away.
Since that unintended regression, git gc --auto only ran for git-am,
git-merge, git-fetch, and git-receive-pack. It was possible to
write a script that would "git commit" a lot of data locally, and gc
would never run.
One such repository that was locally committing generated zone file
changes had grown to a size of ~60GB before a daily cronjob was added
to "git gc", bringing it down to less than 1GB. This will make such
cases work without intervention.
I think fixing such pathological cases where the repository will grow
forever is a worthwhile trade-off for spending a couple of
milliseconds calling "git gc --auto" (in the common cases where it
doesn't do anything).

untracked cache: use git_env_bool() not getenv() for customization
GIT_DISABLE_UNTRACKED_CACHE and GIT_TEST_UNTRACKED_CACHE are only
sensed for their presense by using getenv(); use git_env_bool()
instead so that GIT_DISABLE_UNTRACKED_CACHE=false would work as
naïvely expected.
Also rename GIT_TEST_UNTRACKED_CACHE to GIT_FORCE_UNTRACKED_CACHE
to express what it does more honestly. Forcing its use may be one
useful thing to do while testing the feature, but testing does not
have to be the only use of the knob.
While at it, avoid repeated calls to git_env_bool() by capturing the
return value from the first call in a static variable.
sequencer: do not roll back lockfile unnecessarily
If `commit_lock_file()` or `hold_lock_file_for_update()` fail, there is

which might be confusing.

Certain information is currently shown with --summary, but when used
in combination with --stat it's a bit hard to read since info of the
same file is in two places (--stat and --summary).
On top of that, commits that add or remove files double the number of
display lines, which could be a lot if you add or remove a lot of
files.
--compact-summary embeds most of --summary back in --stat in the
little space between the file name part and the graph line, e.g. with
commit 0433d533f1:
It helps both condensing information and saving some text
space. What's new in diffstat is:
- A new 0644 file is shown as (new)
- A new 0755 file is shown as (new +x)
- A new symlink is shown as (new +l)
- A deleted file is shown as (gone)
- A mode change adding executable bit is shown as (mode +x)
- A mode change removing it is shown as (mode -x)
Note that --compact-summary does not contain all the information
--summary provides. Rewrite percentage is not shown but it could be
added later, like R50% or C20%.

In mark_parents_uninteresting(), we check for the existence of an
object file to see if we should treat a commit as parsed. The result
is to set the "parsed" bit on the commit.
Modify the condition to only check has_object_file() if the result
would change the parsed bit.
When a local branch is different from its upstream ref, "git status"
will compute ahead/behind counts. This uses paint_down_to_common()
and hits mark_parents_uninteresting(). On a copy of the Linux repo
with a local instance of "master" behind the remote branch
"origin/master" by ~60,000 commits, we find the performance of

During abbreviation checks, we navigate to the position within a
pack-index that an OID would be inserted and check surrounding OIDs
for the maximum matching prefix. This position may be beyond the
last position, because the given OID is lexicographically larger
than every OID in the pack. Then nth_packed_object_oid() does not
initialize "oid".
Use the return value of nth_packed_object_oid() to prevent these
errors.
Also the comment about checking near-by objects miscounts the
neighbours. If we have a hit at "first", we check "first-1" and
"first+1" to make sure we have sufficiently long abbreviation not to
match either. If we do not have a hit, "first" is the smallest
among the objects that are larger than what we want to name, so we
check that and "first-1" to make sure we have sufficiently long
abbreviation not to match either. In either case, we only check up
to two near-by objects.

a rename/rename(1to2) conflict. We should only apply directory renames to

test_must_be_empty: make sure the file exists, not just empty
The helper function test_must_be_empty is meant to make sure the
given file is empty, but its implementation is:
if test -s "$1"
then

Surely, the file having non-zero size is a sign that the condition

the file does not even exist. It is an accident waiting to happen

Since Git 1.7.9, "git merge" defaulted to --no-ff (i.e. even when

signed tags from their downstream contributors, but caused an
unnecessary merges when used by downstream contributors who
habitually "catch up" their topic branches with tagged releases
from the upstream. Update "git merge" to default to --no-ff only
