The commit-graph feature has seen a lot of activity in the past
year or so since it was introduced. The feature is a critical
performance enhancement for medium- to large-sized repos, and
does not significantly hurt small repos.
Change the defaults for core.commitGraph and gc.writeCommitGraph
to true so users benefit from this feature by default.
There are several places in the test suite where the environment
variable GIT_TEST_COMMIT_GRAPH is disabled to avoid reading a
commit-graph, if it exists. The config option overrides the
environment, so swap these. Some GIT_TEST_COMMIT_GRAPH assignments
remain, and those are to avoid writing a commit-graph when a new
commit is created.

t6501-freshen-objects.sh sends the standard error from
'git gc' to a file and verifies that it is empty. This
is intended as a way to ensure no warnings are written
during the operation. However, as the commit-graph is
added as a step to 'git gc', its progress will appear
in the output.
Pass the '-q' argument to avoid a failing test case
when progress is written.

There are a few important config settings that are not loaded
during git_default_config. These are instead loaded on-demand.
Centralize these config options to a single scan, and store
all of the values in a repo_settings struct. The values for
each setting are initialized as negative to indicate "unset".
This centralization will be particularly important in a later
change to introduce "meta" config settings that change the
defaults for these config settings.

To avoid data loss, 'git worktree remove' refuses to delete a worktree
if it's dirty or contains untracked files. However, the error message
only mentions that the worktree "is dirty", even if the worktree in
question is in fact clean, but contains untracked files:
$ git worktree add test-worktree
Preparing worktree (new branch 'test-worktree')
HEAD is now at aa53e60 Initial

$ # Huh? Where are those dirty files?!

The grammar for commits used a '?' rather than a '*' on the `merge`
directive line, despite the fact that the code allows multiple `merge`
directives in order to support n-way merges. In fact, elsewhere in
git-fast-import.txt there is an explicit declaration that "an unlimited
number of `merge` commands per commit are permitted by fast-import".
Fix the grammar to match the intent and implementation.

There are two perf scripts numbered p5600, but with otherwise different
names ("clone-reference" versus "partial-clone"). We store timing
results in files named after the whole script, so internally we don't
get confused between the two. But "aggregate.perl" just prints the test
number for each result, giving multiple entries for "5600.3". It also
makes it impossible to skip one test but not the other with
GIT_SKIP_TESTS.
Let's renumber the one that appeared later (by date -- the source of the
problem is that the two were developed on independent branches). For the
non-perf test suite, our test-lint rule would have complained about this
when the two were merged, but t/perf never learned that trick.

Inspired by 21416f0a07 ("restore: fix typo in docs", 2019-08-03), I ran
"git grep -E '(\b[a-zA-Z]+) \1\b' -- Documentation/" to find other cases
where words were duplicated, e.g. "the the", and in most cases removed
one of the repeated words.
There were many false positives by this grep command, including
deliberate repeated words like "really really" or valid uses of "that
that" which I left alone, of course.
I also did not correct any of the legitimate, accidentally repeated
words in old RelNotes.

t1410.3 ("corrupt and checks") fails when run using dash versions
before 0.5.8, with a cryptic message:
mv: cannot stat '.git/objects//e84adb2704cbd49549e52169b4043871e13432': No such file or directory
The function generating that path:
test_oid_to_path () {
echo "${1%${1#??}}/${1#??}"
}
which is supposed to produce a result like
12/3456789....
But a dash bug[*] causes it to instead expand to
/3456789...
The stream of symbols that makes up this function is hard for humans
to follow, too. The complexity mostly comes from the repeated use of
the expression ${1#??} for the basename of the loose object. Use a
variable instead --- nowadays, the dialect of shell used by Git
permits local variables, so this is cheap.
An alternative way to work around [*] is to remove the double-quotes
around test_oid_to_path's return value. That makes the expression
easier for dash to read, but harder for humans. Let's prefer the
rephrasing that's helpful for humans, too.
Noticed by building on Ubuntu trusty, which uses dash 0.5.7.
[*] Fixed by v0.5.8~13 ("[EXPAND] Propagate EXP_QPAT in subevalvar, 2013-08-23).

If the toplevel window for the window being destroyed is the main window
(aka "."), then simply destroying it means the cleanup tasks are not
executed (like saving the commit message buffer, saving window state,
etc.)
All this is handled by do_quit. Call it instead of directly
destroying the main window. For other toplevel windows, the old
behavior remains.

Since the previous commit, our invariant that the_repository is never
NULL is restored, and we can stop being defensive in include_by_branch().
We can confirm the fix by showing that an onbranch config include will
not cause a segfault when run outside a git repository. I've put this in
t1309-early-config since it's related to the case added by 85fe0e800c
(config: work around bug with includeif:onbranch and early config,
2019-07-31), though technically the issue was with
read_very_early_config() and not read_early_config().

We initialize the trace2 system in the common main() function so that
all programs (even ones that aren't builtins) will enable tracing. But
trace2 startup is relatively heavy-weight, as we have to actually read
on-disk config to decide whether to trace. This can cause unexpected
interactions with other common-main initialization. For instance, we'll
end up in the config code before calling initialize_the_repository(),
and the usual invariant that the_repository is never NULL will not hold.
Let's push the trace2 initialization further down in common-main, to
just before we execute cmd_main(). The other parts of the initialization
are much more self-contained and less likely to call library code that
depends on those kinds of invariants.
Originally the trace2 code tried to start as early as possible to get
accurate timings. But the timer initialization was split out from the
config reading in a089724958 (trace2: refactor setting process starting
time, 2019-04-15), so there shouldn't be any impact from this patch.

Commit 85fe0e800c (config: work around bug with includeif:onbranch and
early config, 2019-07-31) tests that our early config-reader does not
access the file mentioned by includeIf.onbranch:refs/heads/master.path.
But it would never do so even if the feature were implemented, since the
onbranch matching code uses the short refname "master".
The test still serves its purpose, since the bug fixed by 85fe0e800c is
actually that we hit a BUG() before even deciding whether to match the
ref. But let's use the correct name to avoid confusion (and which we'll
eventually want to trigger once we do the "real" fix described in that
commit).

Now that --end-of-options is available for any users of

The revision option parser recently learned about --end-of-options, but
that's not quite enough for all callers. Some of them, like git-log,
pick out some options using parse_options(), and then feed the remainder
to setup_revisions(). For those cases we need to stop parse_options()
from finding more options when it sees --end-of-options, and to retain
that option in argv so that setup_revisions() can see it as well.
Let's handle this the same as we do "--". We can even piggy-back on the
handling of PARSE_OPT_KEEP_DASHDASH, because any caller that wants to
retain one will want to retain the other.
I've included two tests here. The "log" test covers "--source", which is
one of the options it handles with parse_options(), and would fail
before this patch. There's also a test that uses the parse-options
helper directly. That confirms that the option is handled correctly even
in cases without KEEP_DASHDASH or setup_revisions(). I.e., it is safe to
use --end-of-options in place of "--" in other programs.
