4d7bc52b17 ("submodule update: allow '.' for branch value",
2016-08-03) adopted from Gerrit a feature to set "." as a special
value of "submodule.<name>.branch" in .gitmodules file to indicate
that the tracking branch in the submodule should be the same as the
current branch in the superproject.
Update the documentation to describe this.

Gerrit has a "superproject subscription" feature[1], that triggers a
commit in a superproject that is subscribed to its submodules.
Conceptually this Gerrit feature can be done on the client side with
Git via (except for raciness, error handling etc):
while [ true ]; do
git -C <superproject> submodule update --remote --force
git -C <superproject> commit -a -m "Update submodules"
git -C <superproject> push
done
for each branch in the superproject. To ease the configuration in Gerrit
a special value of "." has been introduced for the submodule.<name>.branch
to mean the same branch as the superproject[2], such that you can create a
new branch on both superproject and the submodule and this feature
continues to work on that new branch.
Now we find projects in the wild with such a .gitmodules file.
The .gitmodules used in these Gerrit projects do not conform
to Gits understanding of how .gitmodules should look like.
This teaches Git to deal gracefully with this syntax as well.
The redefinition of "." does no harm to existing projects unaware of
this change, as "." is an invalid branch name in Git, so we do not
expect such projects to exist.

In a later patch we want to enhance the logic for the branch selection.
Rewrite the current logic to be in C, so we can directly use C when
we enhance the logic.

When depth is given the user may have a reasonable expectation that
any remote operation is using the given depth. Add a test to demonstrate
we still get the desired sha1 even if the depth is too short to
include the actual commit.

The prior hard coded depth was chosen to be exactly the length from the
recorded gitlink to the tip of the remote, so if you add more commits
to the remote before, this test will not test its intention any more.

Fix recently introduced codepaths that are involved in parallel
submodule operations, which gave up on reading too early, and
could have wasted CPU while attempting to write under a corner
case condition.

The test framework learned a new helper test_match_signal to

One part of "git am" had an oddball helper function that called
stuff from outside "his" as opposed to calling what we have "ours",
which was not gender-neutral and also inconsistent with the rest of
the system where outside stuff is usuall called "theirs" in
contrast to "ours".
* js/am-call-theirs-theirs-in-fallback-3way:
am: counteract gender bias
"gc.autoPackLimit" when set to 1 should not trigger a repacking

so.

For a long time, we carried an in-code comment that said our
colored output would work only when we use fprintf/fputs on
Windows, which no longer is the case for the past few years.

Git does not know what the contents in the index should be for a
path added with "git add -N" yet, so "git grep --cached" should not
show hits (or show lack of hits, with -L) in such a path, but that
logic does not apply to "git grep", i.e. searching in the working
tree files. But we did so by mistake, which has been corrected.
* nd/ita-cleanup:
grep: fix grepping for "intent to add" files
t7810-grep.sh: fix a whitespace inconsistency
t7810-grep.sh: fix duplicated test name
A helper function that takes the contents of a commit object and
finds its subject line did not ignore leading blank lines, as is
commonly done by other codepaths. Make it ignore leading blank
lines to match.
* js/find-commit-subject-ignore-leading-blanks:
reset --hard: skip blank lines when reporting the commit subject
sequencer: use skip_blank_lines() to find the commit subject
commit -C: skip blank lines at the beginning of the message

config.mak.uname: correct perl path on FreeBSD
Recent update to "git daemon" tries to enable the socket-level
KEEPALIVE, but when it is spawned via inetd, the standard input
file descriptor may not necessarily be connected to a socket.
Suppress an ENOTSOCK error from setsockopt().
* ew/daemon-socket-keepalive:
Windows: add missing definition of ENOTSOCK
daemon: ignore ENOTSOCK from setsockopt
"git pack-objects" and "git index-pack" mostly operate with off_t
when talking about the offset of objects in a packfile, but there
were a handful of places that used "unsigned long" to hold that
value, leading to an unintended truncation.
* nd/pack-ofs-4gb-limit:
fsck: use streaming interface for large blobs in pack
pack-objects: do not truncate result in-pack object size on 32-bit systems
index-pack: correct "offset" type in unpack_entry_data()
index-pack: report correct bad object offsets even if they are large
index-pack: correct "len" type in unpack_data()
sha1_file.c: use type off_t* for object_info->disk_sizep
pack-objects: pass length to check_pack_crc() without truncation
"git worktree prune" protected worktrees that are marked as
"locked" by creating a file in a known location. "git worktree"
command learned a dedicated command pair to create and remove such
a file, so that the users do not have to do this with editor.
* nd/worktree-lock:
worktree.c: find_worktree() search by path suffix
worktree: add "unlock" command
worktree: add "lock" command
worktree.c: add is_worktree_locked()
worktree.c: add is_main_worktree()
worktree.c: add find_worktree()
"git notes merge" had a code to see if a path exists (and fails if
it does) and then open the path for writing (when it doesn't).
Replace it with open with O_EXCL.
* rs/notes-merge-no-toctou:
notes-merge: use O_EXCL to avoid overwriting existing files
A few tests that specifically target "git rebase -i" have been
added.

rebase -i: demonstrate a bug with --autosquash
t3404: add a test for the --gpg-sign option
Code cleanup.
* rs/use-strbuf-addbuf:
strbuf: avoid calling strbuf_grow() twice in strbuf_addbuf()
use strbuf_addbuf() for appending a strbuf to another
Existing autoconf generated test for the need to link with pthread
library did not check all the functions from pthread libraries;
recent FreeBSD has some functions in libc but not others, and we
mistakenly thought linking with libc is enough when it is not.
* ew/autoconf-pthread:
configure.ac: stronger test for pthread linkage
"git blame file" allowed the lineage of lines in the uncommitted,
unadded contents of "file" to be inspected, but it refused when
"file" did not appear in the current commit. When "file" was
created by renaming an existing file (but the change has not been
committed), this restriction was unnecessarily tight.
* mh/blame-worktree:
t/t8003-blame-corner-cases.sh: Use here documents
blame: allow to blame paths freshly added to the index
When "git fsck" reports a broken link (e.g. a tree object contains
a blob that does not exist), both containing object and the object
that is referred to were reported with their 40-hex object names.
The command learned the "--name-objects" option to show the path to
the containing object from existing refs (e.g. "HEAD~24^2:file.txt").
* js/fsck-name-object:
fsck: optionally show more helpful info for broken links
fsck: give the error function a chance to see the fsck_options
fsck_walk(): optionally name objects on the go
fsck: refactor how to describe objects
"git add -N dir/file && git write-tree" produced an incorrect tree
when there are other paths in the same directory that sorts after
"file".
* nd/cache-tree-ita:
cache-tree: do not generate empty trees as a result of all i-t-a subentries
cache-tree.c: fix i-t-a entry skipping directory updates sometimes
test-lib.sh: introduce and use $EMPTY_BLOB
test-lib.sh: introduce and use $EMPTY_TREE
"git fetch http://user:pass@host/repo..." scrubbed the userinfo
part, but "git push" didn't.
* jk/push-scrub-url:
t5541: fix url scrubbing test when GPG is not set
push: anonymize URL in status output
Build clean-up.
* nd/test-helpers:
t/test-lib.sh: fix running tests with --valgrind
Makefile: use VCSSVN_LIB to refer to svn library
Makefile: drop extra dependencies for test helpers
"git merge" with renormalization did not work well with
merge-recursive, due to "safer crlf" conversion kicking in when it
shouldn't.
* jc/renormalize-merge-kill-safer-crlf:
merge: avoid "safer crlf" during recording of merge results
convert: unify the "auto" handling of CRLF
