"git status" has long shown essentially the same message as "git
commit"; the message it gives while preparing for the root commit,
i.e. "Initial commit", was hard to understand for some new users.
Now it says "No commits yet" to stress more on the current status
(rather than the commit the user is preparing for, which is more in
line with the focus of "git commit").
* ks/status-initial-commit:
status: contextually notify user about an initial commit
Traditionally, the default die() routine had a code to prevent it
from getting called multiple times, which interacted badly when a
threaded program used it (one downside is that the real error may
be hidden and instead the only error message given to the user may
end up being "die recursion detected", which is not very useful).
* ab/die-errors-in-threaded:
die(): stop hiding errors due to overzealous recursion guard
Fix a recent regression to "git rebase -i" and add tests that would
have caught it and others.
* pw/rebase-i-regression-fix-tests:
t3420: fix under GETTEXT_POISON build
rebase: add more regression tests for console output
rebase: add regression tests for console output
rebase -i: add test for reflog message
sequencer: print autostash messages to stderr
A file can either be added, removed, copied, or renamed, but no two of
these actions can be done by the same patch. Some of these combinations
provoke error messages due to missing file names, and some are only
caught by an assertion. Check git patches already as they are parsed
and report conflicting lines on sight.

An empty string as mode specification is accepted silently by git apply,
as Vegard Nossum found out using AFL. It's interpreted as zero. Reject
such bogus file modes, and only accept ones consisting exclusively of

"git status" learned to optionally give how many stash entries the
user has in its output.
* lb/status-stash-count:
glossary: define 'stash entry'
status: add optional stash count information
stash: update documentation to use 'stash entry'
The preceding bitmap entries have a 1-byte XOR-offset and 1-byte flags,
so their size is not a multiple of 4. Thus the name-hash cache is only
guaranteed to be 2-byte aligned and so we must use get_be32 rather than
indexing the array directly.

has_sha1_file_with_flags() implements many mechanisms in common with

Currently, regardless of the contents of the "struct object_info" passed
to sha1_object_info_extended(), that function always accesses the
packfile whenever it returns information about a packed object, since it
needs to populate "u.packed".
Add the ability to pass NULL, and use NULL-ness of the argument to
activate an optimization in which sha1_object_info_extended() does not
needlessly access the packfile. A subsequent patch will make use of this
optimization.
A similar optimization is not made for the cached and loose cases as it
would not cause a significant performance improvement.

Since f6ecc62dbf (write_shared_index(): use tempfile module, 2015-08-10)
write_shared_index() has been using mks_tempfile() to create the
temporary file that will become the shared index.
But even before that, it looks like the functions used to create this
file didn't call adjust_shared_perm(), which means that the shared
index file has always been created with 600 permissions regardless
of the shared permission settings.
Because of that, on repositories created with `git init --shared=all`
and using the split index feature, one gets an error like:
fatal: .git/sharedindex.a52f910b489bc462f187ab572ba0086f7b5157de: index file open failed: Permission denied
when another user performs any operation that reads the shared index.
Call adjust_shared_perm() on the temporary file created by
mks_tempfile() ourselves to adjust the permission bits.

The result from "git diff" that compares two blobs, e.g. "git diff
