Both "git ls-remote -h" and "git grep -h" give short usage help,
like any other Git subcommand, but it is not unreasonable to expect
that the former would behave the same as "git ls-remote --head"
(there is no other sensible behaviour for the latter). The
documentation has been updated in an attempt to clarify this.

"git rebase -i" identifies existing commits in its todo file with
their abbreviated object name, which could become ambigous as it
goes to create new commits, and has a mechanism to avoid ambiguity

not covered by the protection against ambiguity, which has been
corrected.

If there is no worktree at present, we can still hint the user about
Git's current directory by showing them the absolute path to the Git
directory. Even though the Git directory doesn't make it as easy to
locate the worktree in question, it can still help a user figure out
what's going on while developing a script.
This fixes a segmentation fault introduced in e0020b2f
("prefix_path: show gitdir when arg is outside repo", 2020-02-14).

Several tests wanted to verify that files were actually modified by a
merge, which it would do by checking that the mtime was updated. In
order to avoid problems with the merge completing so fast that the mtime
at the beginning and end of the operation was the same, these tests
would first set the mtime of a file to something "old". This "old"
value was usually determined as current system clock minus one second,
truncated to the nearest integer. Unfortunately, it appears the system
clock and filesystem clock are different and comparing across the two
runs into race problems resulting in flaky tests.
From https://stackoverflow.com/questions/14392975/timestamp-accuracy-on-ext4-sub-millsecond:
date will call the gettimeofday system call which will always return
the most accurate time available based on the cached kernel time,
adjusted by the CPU cycle time if available to give nanosecond
resolution. The timestamps stored in the file system however, are
only based on the cached kernel time. ie The time calculated at the
last timer interrupt.
and from https://apenwarr.ca/log/20181113:
Does mtime get set to >= the current time?
No, this depends on clock granularity. For example, gettimeofday()
can return times in microseconds on my system, but ext4 rounds
timestamps down to the previous ~10ms (but not exactly 10ms)
increment, with the surprising result that a newly-created file is
almost always created in the past:
$ python -c "
import os, time
t0 = time.time()
open('testfile', 'w').close()
print os.stat('testfile').st_mtime - t0
"
-0.00234484672546
So, instead of trying to compare across what are effectively two
different clocks, just avoid using the system clock. Any new updates to
files have to give an mtime at least as big as what is already in the
file, so we could define "old" as one second before the mtime found in
the file before the merge starts. But, to avoid problems with leap
seconds, ntp updates, filesystems that only provide two second
resolution, and other such weirdness, let's just pick an hour before the
mtime found in the file before the merge starts.
Also, clarify in one test where we check the mtime of different files
that it really was intentional. I totally forgot the reasons for that
and assumed it was a bug when asked.

Band-aid fixes for two fallouts from switching the default "rebase"
backend.
* en/rebase-backend:
git-rebase.txt: highlight backend differences with commit rewording
sequencer: clear state upon dropping a become-empty commit
i18n: unmark a message in rebase.c

As noted by Junio:
Back when "git am" was written, it was not considered a bug that the
"git am --resolved" option did not offer the user a chance to update
the log message to match the adjustment of the code the user made,
but honestly, I'd have to say that it is a bug in "git am" in that
over time it wasn't adjusted to the new world order where we
encourage users to describe what they did when the automation
hiccuped by opening an editor. These days, even when automation
worked well (e.g. a clean auto-merge with "git merge"), we open an
editor. The world has changed, and so should the expectations.
Junio also suggested providing a workaround such as allowing --no-edit
together with git rebase --continue, but that should probably be done in
a patch after the git-2.26.0 release. For now, just document the known
difference in the Behavioral Differences section.

In commit e98c4269c8 ("rebase (interactive-backend): fix handling of
commits that become empty", 2020-02-15), the merge backend was changed
to drop commits that did not start empty but became so after being
applied (because their changes were a subset of what was already
upstream). This new code path did not need to go through the process of
creating a commit, since we were dropping the commit instead.
Unfortunately, this also means we bypassed the clearing of the
CHERRY_PICK_HEAD and MERGE_MSG files, which if there were no further
commits to cherry-pick would mean that the rebase would end but assume
there was still an operation in progress. Ensure that we clear such
state files when we decide to drop the commit.

Recently we inadvertently added a few instances of using 0-width
format string to functions that we mark as printf-like without any
developers noticing. The root cause was that the compiler warning
that is triggered by this is almost always useless and we disabled
the warning in our developer builds, but not for general public.
The new instances have been corrected, and the warning has been
resurrected in the developer builds.
