"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").

The existing message, "Initial commit", makes sense for the commit template
notifying users that it's their initial commit, but is confusing when
merely checking the status of a fresh repository (or orphan branch)
without having any commits yet.
Change the output of "status" to say "No commits yet" when "git
status" is run on a fresh repo (or orphan branch), while retaining the
current "Initial commit" message displayed in the template that's
displayed in the editor when the initial commit is being authored.
Correspondingly change the output of "short status" to "No commits yet
on " when "git status -sb" is run on a fresh repo (or orphan branch).
A few alternatives considered were,
* Waiting for initial commit
* Your current branch does not have any commits
* Current branch waiting for initial commit
The most succint one among the alternatives was chosen.

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).

Change the recursion limit for the default die routine from a *very*
low 1 to 1024. This ensures that infinite recursions are broken, but
doesn't lose the meaningful error messages under threaded execution
where threads concurrently start to die.
The intent of the existing code, as explained in commit
cd163d4b4e ("usage.c: detect recursion in die routines and bail out
immediately", 2012-11-14), is to break infinite recursion in cases
where the die routine itself calls die(), and would thus infinitely
recurse.
However, doing that very aggressively by immediately printing out
"recursion detected in die handler" if we've already called die() once
means that threaded invocations of git can end up only printing out
the "recursion detected" error, while hiding the meaningful error.
An example of this is running a threaded grep which dies on execution
against pretty much any repo, git.git will do:
git grep -P --threads=8 '(*LIMIT_MATCH=1)-?-?-?---$'
With the current version of git this will print some combination of
multiple PCRE failures that caused the abort and multiple "recursion
detected", some invocations will print out multiple "recursion
detected" errors with no PCRE error at all!
Before this change, running the above grep command 1000 times against
git.git[1] and taking the top 20 results will on my system yield the
following distribution of actual errors ("E") and recursion
errors ("R"):
322 E R
306 E
116 E R R
65 R R
54 R E
49 E E
44 R
15 E R R R
9 R R R
7 R E R
5 R R E
3 E R R R R
2 E E R
1 R R R R
1 R R R E
1 R E R R
The exact results are obviously random and system-dependent, but this
shows the race condition in this code. Some small part of the time
we're about to print out the actual error ("E") but another thread's
recursion error beats us to it, and sometimes we print out nothing but
the recursion error.
With this change we get, now with "W" to mean the new warning being
emitted indicating that we've called die() many times:
502 E
160 E W E
120 E E
53 E W
35 E W E E
34 W E E
29 W E E E
16 E E W
16 E E E
11 W E E E E
7 E E W E
4 W E
3 W W E E
2 E W E E E
1 W W E
1 W E W E
1 E W W E E E
1 E W W E E
1 E W W E
1 E W E E W
Which still sucks a bit, due to a still present race-condition in this
code we're sometimes going to print out several errors still, or
several warnings, or two duplicate errors without the warning.
But we will never have a case where we completely hide the actual
error as we do now.
Now, git-grep could make use of the pluggable error facility added in
commit c19a490e37 ("usage: allow pluggable die-recursion checks",
2013-04-16). There's other threaded code that calls set_die_routine()
or set_die_is_recursing_routine().
But this is about fixing the general die() behavior with threading
when we don't have such a custom routine yet. Right now the common
case is not an infinite recursion in the handler, but us losing error
messages by default because we're overly paranoid about our recursion
check.
So let's just set the recursion limit to a number higher than the
number of threads we're ever likely to spawn. Now we won't lose
errors, and if we have a recursing die handler we'll still die within
microseconds.
There are race conditions in this code itself, in particular the
"dying" variable is not thread mutexed, so we e.g. won't be dying at
exactly 1024, or for that matter even be able to accurately test
"dying == 2", see the cases where we print out more than one "W"
above.
But that doesn't really matter, for the recursion guard we just need
to die "soon", not at exactly 1024 calls, and for printing the correct
error and only one warning most of the time in the face of threaded
death this is good enough and a net improvement on the current code.

Newly added tests to t3420 in this series prepare expected
human-readable output from "git rebase -i" and then compare the
actual output with it. As the output from the command is designed
to go through i18n/l10n, we need to use test_i18ncmp to tell
GETTEXT_POISON build that it is OK the output does not match.

The rebase messages are printed to stderr traditionally. However due
to a bug introduced in 587947750bd (rebase: implement --[no-]autostash
and rebase.autostash, 2013-05-12) which was faithfully copied when
reimplementing parts of the interactive rebase in the sequencer the
autostash messages are printed to stdout instead.
It is time to fix that: let's print the autostash messages to stderr
instead of stdout.

When help.autoCorrect is enabled, an invalid git command prints a

The continuation message's phrasing is awkward. This commit cleans it up.
As a bonus, we now use full-sentence strings which make translation easier.

Since c9d961647 (i18n: add--interactive: mark
edit_hunk_manually message for translation, 2016-12-14),
when the user asks to edit a hunk manually, we respect
core.commentChar in generating the edit instructions.
However, when we then strip out comment lines, we use a
simple regex like:
/^$commentChar/
If your chosen comment character is a regex metacharacter,
then that will behave in a confusing manner ("$", for
instance, would only eliminate blank lines, not actual
comment lines).
We can fix that by telling perl not to respect
metacharacters.

The prompt_yesno function loops indefinitely waiting for a
"y" or "n" response. But it doesn't handle EOF, meaning
that we can end up in an infinite loop of reading EOF from
stdin. One way to simulate that is with:
echo e | GIT_EDITOR='echo corrupt >' git add -p
Let's break out of the loop and propagate the undef to the
caller. Without modifying the callers that effectively turns
it into a "no" response. This is reasonable for both of the
current callers, and it leaves room for any future caller to
check for undef explicitly.

`for_each_bisect_ref()` is called by `for_each_bad_bisect_ref()` with
a term "bad". This used to make it call `for_each_ref_in_submodule()`
with a prefix "refs/bisect/bad". But the latter is the name of the
reference that is being sought, so the empty string was being passed
to the callback as the trimmed refname. Moreover, this questionable
practice was turned into an error by
b9c8e7f2fb prefix_ref_iterator: don't trim too much, 2017-05-22
It makes more sense (and agrees better with the documentation of
`--bisect`) for the callers to receive the full reference names. So
* Add a new function, `for_each_fullref_in_submodule()`, to the refs
API. This plugs a gap in the existing functionality, analogous to
`for_each_fullref_in()` but accepting a `submodule` argument.
* Change `for_each_bad_bisect_ref()` to call the new function rather
than `for_each_ref_in_submodule()`.
* Add a test.

Commit 28ed9830b1 (get_packed_ref_cache(): assume "packed-refs" won't
change while locked, 2017-05-22) assumes that the "packed-refs" file
cannot change while we hold the lock. That assumption is
justified *if* the lock has been held the whole time since the
"packed-refs" file was last read.
But in `lock_packed_refs()`, we ourselves lock the "packed-refs" file
and then call `get_packed_ref_cache()` to ensure that the cache agrees
with the file. The intent is to guard against the possibility that
another process changed the "packed-refs" file the moment before we
locked it.
This check was defeated because `get_packed_ref_cache()` saw that the
file was locked, and therefore didn't do the `stat_validity_check()`
that we want.
The mistake was compounded with a misleading comment in
`lock_packed_refs()` claiming that it was doing the right thing. That
comment came from an earlier draft of the mh/packed-ref-store-prep
patch series when the commits were in a different order.
So instead:
* Extract a function `validate_packed_ref_cache()` that does the
validity check independent of whether the lock is held.
* Change `get_packed_ref_cache()` to call the new function, but only
if the lock *isn't* held.
* Change `lock_packed_refs()` to call the new function in any case
before calling `get_packed_ref_cache()`.
* Fix the comment in `lock_packed_refs()`.

The result from "git diff" that compares two blobs, e.g. "git diff
$commit1:$path $commit2:$path", used to be shown with the full
object name as given on the command line, but it is more natural to
use the $path in the output and use it to look up .gitattributes.

A common pattern to free a piece of memory and assign NULL to the
pointer that used to point at it has been replaced with a new
FREE_AND_NULL() macro.

Replace occurrences of `free(ptr); ptr = NULL` which weren't caught by
the coccinelle rule. These fall into two categories:
- free/NULL assignments one after the other which coccinelle all put
on one line, which is functionally equivalent code, but very ugly.
- manually spotted occurrences where the NULL assignment isn't right
after the free() call.

Add a FREE_AND_NULL() wrapper marco for the common pattern of freeing
a pointer and assigning NULL to it right afterwards.
The implementation is similar to the (currently unused) XDL_PTRFREE
macro in xdiff/xmacros.h added in commit 3443546f6e ("Use a *real*
built-in diff generator", 2006-03-24). The only difference is that
free() is called unconditionally, see [1].
See [2] for a suggested alternative which does this via a function
instead of a macro. As covered in replies to that message, while it's
a viable approach, it would introduce caveats which this approach
doesn't have, so that potential change is left to a future follow-up
change.
This merely allows us to translate exactly what we're doing now to a
less verbose & idiomatic form using a macro, while guaranteeing that
we don't introduce any functional changes.

Using "git add d/i/r" when d/i/r is the top of the working tree of
a separate repository would create a gitlink in the index, which
would appear as a not-quite-initialized submodule to others. We
learned to give warnings when this happens.
