The advice message to tell the user to migrate an existing graft
file to the replace system when a graft file was read was shown
even when "git replace --convert-graft-file" command, which is the
way the message suggests to use, was running, which made little
sense.
* ab/replace-graft-with-replace-advice:
advice: don't pointlessly suggest --convert-graft-file
"git rebase --stat" to transplant a piece of history onto a totally
unrelated history were not working before and silently showed wrong
result. With the recent reimplementation in C, it started to instead
die with an error message, as the original logic was not prepared
to cope with this case. This has now been fixed.
* js/rebase-stat-unrelated-fix:
rebase --stat: fix when rebasing to an unrelated history
When rebasing to a commit history that has no common commits with the
current branch, there is no merge base. In diffstat mode, this means
that we cannot compare to the merge base, but we have to compare to the
empty tree instead.
Also, if running in verbose diffstat mode, we should not output
Changes from <merge-base> to <onto>
as that does not make sense without any merge base.
Note: neither scripted nor built-in versoin of `git rebase` were
prepared for this situation well. We use this opportunity not only to
fix the bug(s), but also to make both versions' output consistent in
this instance. And add a regression test to keep this working in all
eternity.

The scripted version of "rebase" honored the `GIT_REFLOG_ACTION`,
and some automation scripts expected the reflog entries to be
prefixed with "rebase -i", not "rebase", after running "rebase -i".
This regressed in the reimplementation in C.
Fix that, and add a regression test, both with `GIT_REFLOG_ACTION`
set and unset.
Note: the reflog message for "rebase finished" did *not* honor
GIT_REFLOG_ACTION, and as we are very late in the v2.20.0-rcN phase,
we leave that bug for later (as it seems that that bug has been with
us from the very beginning).

The advice to run 'git replace --convert-graft-file' added in
f9f99b3f7d ("Deprecate support for .git/info/grafts", 2018-04-29)
didn't add an exception for the 'git replace --convert-graft-file'
codepath itself.
As a result we'd suggest running --convert-graft-file while the user
was running --convert-graft-file, which makes no sense. Before:
$ git replace --convert-graft-file
hint: Support for <GIT_DIR>/info/grafts is deprecated
hint: and will be removed in a future Git version.

hint: Please use "git replace --convert-graft-file"
hint: to convert the grafts into replace refs.
hint:
hint: Turn this message off by running
hint: "git config advice.graftFileDeprecated false"
Add a check for that case and skip printing the advice while the user
is busy following our advice.

Test scripts checking 'git daemon' stop the daemon with a TERM signal,
and the 'stop_git_daemon' helper checks the daemon's exit status to
make sure that it indeed died because of that signal.
This check is bogus since 03c39b3458 (t/lib-git-daemon: use
test_match_signal, 2016-06-24), for two reasons:
- Right after killing 'git daemon', 'stop_git_daemon' saves its exit
status in a variable, but since 03c39b3458 the condition checking
the exit status looks at '$?', which at this point is not the exit
status of 'git daemon', but that of the variable assignment, i.e.
it's always 0.
- The unexpected exit status should abort the whole test script with
'error', but it doesn't, because 03c39b3458 forgot to negate
'test_match_signal's exit status in the condition.
This patch fixes both issues.

clone: fix colliding file detection on APFS
Commit b878579ae7 (clone: report duplicate entries on case-insensitive
filesystems - 2018-08-17) adds a warning to user when cloning a repo
with case-sensitive file names on a case-insensitive file system. The
"find duplicate file" check was doing by comparing inode number (and
only fall back to fspathcmp() when inode is known to be unreliable
because fspathcmp() can't cover all case folding cases).
The inode check is very simple, and wrong. It compares between a
32-bit number (sd_ino) and potentially a 64-bit number (st_ino). When
an inode is larger than 2^32 (which seems to be the case for APFS), it
will be truncated and stored in sd_ino, but comparing with itself will
fail.
As a result, instead of showing a pair of files that have the same
name, we show just one file (marked before the beginning of the
loop). We fail to find the original one.
The fix could be just a simple type cast (*)
dup->ce_stat_data.sd_ino == (unsigned int)st->st_ino
but this is no longer a reliable test, there are 4G possible inodes
that can match sd_ino because we only match the lower 32 bits instead
of full 64 bits.
There are two options to go. Either we ignore inode and go with
fspathcmp() on Apple platform. This means we can't do accurate inode
check on HFS anymore, or even on APFS when inode numbers are still
below 2^32.
Or we just to to reduce the odds of matching a wrong file by checking
more attributes, counting mostly on st_size because st_xtime is likely
the same. This patch goes with this direction, hoping that false
positive chances are too small to be seen in practice.
While at there, enable the test on Cygwin (verified working by Ramsay
Jones)

Since 3b1d9e04 (eoie: add End of Index Entry (EOIE) extension,
2018-10-10) Git defaults to writing the new EOIE section when writing
out an index file. Usually that is a good thing because it improves
threaded performance, but when a Git repository is shared with older
versions of Git, it produces a confusing warning:
$ git status
ignoring EOIE extension
HEAD detached at 371ed0defa
nothing to commit, working tree clean
Let's introduce the new index extension more gently. First we'll roll
out the new version of Git that understands it, and then once
sufficiently many users are using such a version, we can flip the
default to writing it by default.
Introduce a '[index] recordEndOfIndexEntries' configuration variable
to allow interested users to benefit from this index extension early.

The 'test_cmp_rev' helper is merely a wrapper around 'test_cmp'
checking the output of two 'git rev-parse' commands, which means that
its output on failure is not particularly informative, as it's
basically two OIDs with a bit of extra clutter of the diff header, but
without any indication of which two revisions have caused the failure:
--- expect.rev 2018-11-17 14:02:11.569747033 +0000
+++ actual.rev 2018-11-17 14:02:11.569747033 +0000

+139b20d8e6c5b496de61f033f642d0e3dbff528d
It also pollutes the test repo with these two intermediate files,
though that doesn't seem to cause any complications in our current
tests (meaning that I couldn't find any tests that have to work around
the presence of these files by explicitly removing or ignoring them).
Enhance 'test_cmp_rev' to provide a more useful output on failure with
less clutter:
error: two revisions point to different objects:
'HEAD^': d79ce1670bdcb76e6d1da2ae095e890ccb326ae9
'extra': 139b20d8e6c5b496de61f033f642d0e3dbff528d
Doing so is more convenient when storing the OIDs outputted by 'git
rev-parse' in a local variable each, which, as a bonus, won't pollute
the repository with intermediate files.
While at it, also ensure that 'test_cmp_rev' is invoked with the right
number of parameters, namely two.

Some of the functions in our test library check that they were invoked
properly with conditions like this:
test "$#" = 2 ||
error "bug in the test script: not 2 parameters to test-expect-success"
If this particular condition is triggered, then 'error' will abort the
whole test script with a bold red error message [1] right away.
However, under certain circumstances the test script will be aborted
completely silently, namely if:
- a similar condition in a test helper function like
'test_line_count' is triggered,
- which is invoked from the test script's "main" shell [2],
- and the test script is run manually (i.e. './t1234-foo.sh' as
opposed to 'make t1234-foo.sh' or 'make test') [3]
- and without the '--verbose' option,
because the error message is printed from within 'test_eval_', where
standard output is redirected either to /dev/null or to a log file.
The only indication that something is wrong is that not all tests in
the script are executed and at the end of the test script's output
there is no "# passed all N tests" message, which are subtle and can
easily go unnoticed, as I had to experience myself.
Send these "bug in the test script" error messages directly to the
test scripts standard error and thus to the terminal, so those bugs
will be much harder to overlook. Instead of updating all ~20 such
'error' calls with a redirection, let's add a BUG() function to
'test-lib.sh', wrapping an 'error' call with the proper redirection
and also including the common prefix of those error messages, and
convert all those call sites [4] to use this new BUG() function
instead.
[1] That particular error message from 'test_expect_success' is
printed in color only when running with or without '--verbose';
with '--tee' or '--verbose-log' the error is printed without
color, but it is printed to the terminal nonetheless.
[2] If such a condition is triggered in a subshell of a test, then
'error' won't be able to abort the whole test script, but only the
subshell, which in turn causes the test to fail in the usual way,
indicating loudly and clearly that something is wrong.
[3] Well, 'error' aborts the test script the same way when run
manually or by 'make' or 'prove', but both 'make' and 'prove' pay
attention to the test script's exit status, and even a silently
aborted test script would then trigger those tools' usual
noticable error messages.
[4] Strictly speaking, not all those 'error' calls need that
redirection to send their output to the terminal, see e.g.
'test_expect_success' in the opening example, but I think it's
better to be consistent.
