The index might be aware that a file hasn't modified via fsmonitor, but
unpack-trees did not pay attention to it and checked via ie_match_stat
which can be inefficient on certain filesystems. This significantly slows
down commands that run oneway_merge, like checkout and reset --hard.
This patch makes oneway_merge check whether a file is considered
unchanged through fsmonitor and skips ie_match_stat on it. unpack-trees
also now correctly copies over fsmonitor validity state from the source
index. Finally, for correctness, we force a refresh of fsmonitor state in
tweak_fsmonitor.
After this change, commands like stash (that use reset --hard
internally) go from 8s or more to ~2s on a 250k file repository on a
mac.

r1=$(git rev-parse --verify "$1") &&
r2=$(git rev-parse --verify "$2") &&
`! test_cmp_rev` will succeed if any of the rev-parses fail. This
behavior is not desired. We want the rev-parses to _always_ be
successful.
Rewrite test_cmp_rev() to optionally accept "!" as the first argument to
do a not-equals comparison. Rewrite `! test_cmp_rev` to `test_cmp_rev !`
in all tests to take advantage of this new functionality.
Also, rewrite the rev-parse logic to end with a `|| return 1` instead of
&&-chaining into the rev-comparison logic. This makes it obvious to

According to POSIX enhancement request '0000767: Add built-in

dash only allows one variable in a local definition; it permits
assignment though it doesn't document that clearly.
however, this isn't true since t0000 still passes with this patch
applied on dash 0.5.10.2. Needless to say, since `local` isn't POSIX
standardized, it is not exactly clear what `local` entails on different

Although `--notes=` accepts and handles a tree-ish just fine, it isn't a

makes it harder to click in users' minds that the argument here is the
same type as the `notes.displayRef` configuration variable, for example.
Change `treeish` to `ref` so that it will be easier for users to make

Note that we don't completely lose the notion that `--notes=` can accept

The standard format for referencing other commits within some projects
(such as git.git) is the reference format. This is described in
Documentation/SubmittingPatches as
If you want to reference a previous commit in the history of a stable
branch, use the format "abbreviated hash (subject, date)", like this:
....
Commit f86a374 (pack-bitmap.c: fix a memleak, 2015-03-30)
noticed that ...
....
Since this format is so commonly used, standardize it as a pretty
format.
The tests that are implemented essentially show that the format-string
does not change in response to various log options. This is useful
because, for future developers, it shows that we've considered the
limitations of the "canned format-string" approach and we are fine with
them.

Quoting SZEDER Gábor[1],
SubmittingPatches is simply wrong: our de-facto standard format for
referencing other commits does not enclose the subject in a pair of
double-quotes:
$ git log v2.24.0 |grep -E '[0-9a-f]{7} \("' |wc -l
785
$ git log v2.24.0 |grep -E '[0-9a-f]{7} \([^"]' |wc -l
2276
Those double-quotes don't add any value to the references, but they
result in weird looking references for 1083 of our commits whose
subject lines happen to end with double-quotes, e.g.:
f23a465132 ("hashmap_get{,_from_hash} return "struct hashmap_entry *"", 2019-10-06)
and without those unnecessary pair of double-quotes we would have
~3000 more commits whose summary would fit on a single line.
Remove references to the enclosing double-quotes from SubmittingPatches
since our de-facto standard for referencing commits does not actually
use them.

'git unpack-objects' shows a progress line only counting the number of
unpacked objects, so if some of the received objects are unusually
large, then that progress might appear to be frozen while processing
such a larger object. I just stared at a seemingly stuck progress
line for over half a minute, while 'git fetch' was busy receiving a
pack with only a couple of objects (i.e. fewer than
'fetch.unpackLimit'), with one of them being over 80MB.
Display throughput in 'git unpack-objects' progress line, so we show
that something is going on even when receiving and processing a large
object.
Counting the consumed bytes is far away from the place that
counts objects and displays progress, and to pass around the 'struct
progress' instance we would have to modify the signature of five
functions and 14 of their callsites: this is just too much churn, so
let's rather make it file-scope static.
'git index-pack', i.e. the non-unpacking cousin of 'git
unpack-objects' already includes throughput in its progress line, and
it uses a file-scope static 'struct progress' instance as well.

Ever since it was introduced in 7cceca5ccc (Add 'git rev-parse

treated a missing working tree as a quiet success: it neither prints a
toplevel path, but nor does it report any kind of error.
While a caller could distinguish this case by looking for an empty
response, the behavior is rather confusing. We're better off complaining
that there is no working tree, as other internal commands would do in
similar cases (e.g., "git status" or any builtin with NEED_WORK_TREE set
would just die()). So let's do the same here.
