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.

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

needs.

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.

There's currently no robust way to tell Git that a particular option is
meant to be a revision, and not an option. So if you have a branch
"refs/heads/--foo", you cannot just say:
git rev-list --foo
You can say:
git rev-list refs/heads/--foo
But that breaks down if you don't know the refname, and in particular if
you're a script passing along a value from elsewhere. In most programs,
you can use "--" to end option parsing, like this:
some-prog -- "$revision"
But that doesn't work for the revision parser, because "--" is already
meaningful there: it separates revisions from pathspecs. So we need some
other marker to separate options from revisions.
This patch introduces "--end-of-options", which serves that purpose:
git rev-list --oneline --end-of-options "$revision"
will work regardless of what's in "$revision" (well, if you say "--" it
may fail, but it won't do something dangerous, like triggering an
unexpected option).
The name is verbose, but that's probably a good thing; this is meant to
be used for scripted invocations where readability is more important
than terseness.
One alternative would be to introduce an explicit option to mark a
revision, like:
git rev-list --oneline --revision="$revision"
That's slightly _more_ informative than this commit (because it makes
even something silly like "--" unambiguous). But the pattern of using a
separator like "--" is well established in git and in other commands,
and it makes some scripting tasks simpler like:
git rev-list --end-of-options "$@"
There's no documentation in this patch, because it will make sense to
describe the feature once it is available everywhere (and support will
be added in further patches).

Ever since commit 8c8e5bd6eb ("merge-recursive: switch directory
rename detection default", 2019-04-05), the default handling with
directory rename detection was to report a conflict and leave unstaged
entries in the index. However, when creating a virtual merge base in
the recursive case, we absolutely need a tree, and the only way a tree
can be written is if we have no unstaged entries -- otherwise we hit a
BUG().
There are a few fixes possible here which at least fix the BUG(), but
none of them seem optimal for other reasons; see the comments with the
new testcase 13e in t6043 for details (which testcase triggered a BUG()
prior to this patch). As such, just opt for a very conservative and
simple choice that is still relatively reasonable: have the recursive
case treat 'conflict' as 'false' for opt->detect_directory_renames.

The verbose output of every test looks something like this:
expecting success:
echo content >file &&
git add file &&
git commit -m "add file"
[master (root-commit) d1fbfbd] add file
Author: A U Thor <author@example.com>
1 file changed, 1 insertion(+)
create mode 100644 file
ok 1 - commit works
i.e. first an "expecting success" (or "checking known breakage") line
followed by the commands to be executed, then the output of those
comamnds, and finally an "ok"/"not ok" line containing the test name.
Note that the test's name is only shown at the very end.
With '-x' tracing enabled and/or in longer tests the verbose output
might be several screenfulls long, making it harder than necessary to
find where the output of the test with a given name starts (especially
when the outputs to different file descriptors are racing, and the
"expecting success"/command block arrives earlier than the "ok" line
of the previous test).
Print the test name at the start of the test's verbose output, i.e. at
the end of the "expecting success" and "checking known breakage"
lines, to make the start of a particular test a bit easier to
recognize. Also print the test script and test case numbers, to help
those poor souls who regularly have to scan through the combined
verbose output of several test scripts.
So the dummy test above would start like this:
expecting success of 9999.1 'commit works':
echo content >file &&

Our test scripts are named something like 't1234-command.sh', but the
script names used in 't0000-basic.sh' don't follow this naming
convention. Normally this doesn't matter, because the test scripts
themselves don't care how they are called. However, the next patch
will start to include the test number in the test's verbose output, so
the test script's name will matter in the two tests checking the
verbose output.
Update the tests 'test --verbose' and 'test --verbose-only' to follow
out test script naming convention.
Leave the other tests in 't0000' unchanged: changing the names of
their test scripts would be only pointless code churn.

In 1771be90 "commit-graph: merge commit-graph chains" (2019-06-18),
the method sort_and_scan_merged_commits() was added to merge the
commit lists of two commit-graph files in the incremental format.
Unfortunately, there was an off-by-one error in that method around
incrementing num_extra_edges, which leads to an incorrect offset
for the base graph chunk.
When we store an octopus merge in the commit-graph file, we store
the first parent in the normal place, but use the second parent
position to point into the "extra edges" chunk where the remaining
parents exist. This means we should be adding "num_parents - 1"
edges to this list, not "num_parents - 2". That is the basic error.
The reason this was not caught in the test suite is more subtle.
In 5324-split-commit-graph.sh, we test creating an octopus merge
and adding it to the tip of a commit-graph chain, then verify the
result. This _should_ have caught the problem, except that when
we load the commit-graph files we were overly careful to not fail
when the commit-graph chain does not match. This care was on
purpose to avoid race conditions as one process reads the chain
and another process modifies it. In such a case, the reading
process outputs the following message to stderr:
warning: commit-graph chain does not match
These warnings are output in the test suite, but ignored. By
checking the stderr of `git commit-graph verify` to include
the expected progress output, it will now catch this error.

While 'git commit-graph write --stdin-commits' expects commit object
ids as input, it accepts and silently skips over any invalid commit
object ids, and still exits with success:
# nonsense
$ echo not-a-commit-oid | git commit-graph write --stdin-commits
$ echo $?
0
# sometimes I forgot that refs are not good...
$ echo HEAD | git commit-graph write --stdin-commits
$ echo $?
0
# valid tree OID, but not a commit OID
$ git rev-parse HEAD^{tree} | git commit-graph write --stdin-commits
$ echo $?
0
$ ls -l .git/objects/info/commit-graph
ls: cannot access '.git/objects/info/commit-graph': No such file or directory
Check that all input records are indeed valid commit object ids and
return with error otherwise, the same way '--stdin-packs' handles
invalid input; see e103f7276f (commit-graph: return with errors during
write, 2019-06-12).
Note that it should only return with error when encountering an
invalid commit object id coming from standard input. However,
'--reachable' uses the same code path to process object ids pointed to
by all refs, and that includes tag object ids as well, which should
still be skipped over. Therefore add a new flag to 'enum
commit_graph_write_flags' and a corresponding field to 'struct
write_commit_graph_context', so we can differentiate between those two
cases.
