aa097b88e9 approxidate: fix NULL dereference in date_time()
When we see a time like "noon", we pass "12" to our date_time() helper,
which sets the hour to 12pm. If the current time is before noon, then we
wrap around to yesterday using date_yesterday(). But unlike the normal
calls to date_yesterday() from approxidate_alpha(), we pass a NULL "num"
parameter. Since c27cc94fad (approxidate: handle pending number for
"specials", 2018-11-02), that causes a segfault.

One way to fix this is by checking for NULL. But arguably date_time() is
abusing our helper by passing NULL in the first place (and this is the
only case where one of these "special" parsers is used this way). So
instead, let's have it just do the 1-day subtraction itself. It's still
just a one-liner due to our update_tm() helper.

Note that the test added here is a little funny, as we say "10am noon",
which makes the "10am" seem pointless.  But this bug can only be
triggered when it the currently-parsed hour is before the special time.
The latest special time is "tea" at 1700, but t0006 uses a hard-coded
TEST_DATE_NOW of 1900. We could reset TEST_DATE_NOW, but that may lead
to confusion in other tests. Just saying "10am noon" makes this test
self-contained.

b7845cebc0 tree-walk.c: fix overoptimistic inclusion in :(exclude) matching
tree_entry_interesting() is used for matching pathspec on a tree. The
interesting thing about this function is that, because the tree
entries are known to be sorted, this function can return more than
just "yes, matched" and "no, not matched". It can also say "yes, this
entry is matched and so is the remaining entries in the tree".

This is where I made a mistake when matching exclude pathspec. For
exclude pathspec, we do matching twice, one with positive patterns and
one with negative ones, then a rule table is applied to determine the
final "include or exclude" result. Note that "matched" does not
necessarily mean include. For negative patterns, "matched" means
exclude.

This particular rule is too eager to include everything. Rule 8 says
that "if all entries are positively matched" and the current entry is
not negatively matched (i.e. not excluded), then all entries are
positively matched and therefore included. But this is not true. If
the _current_ entry is not negatively matched, it does not mean the
next one will not be and we cannot conclude right away that all
remaining entries are positively matched and can be included.

Rules 8 and 18 are now updated to be less eager. We conclude that the
current entry is positively matched and included. But we say nothing
about remaining entries. tree_entry_interesting() will be called again
for those entries where we will determine entries individually.

'from' array. Add tests that check this method works in a few

1. All commits in the 'to' list are reachable. This exercises the

2. Some commits in the 'to' list are reachable. This exercises the

3. No commits in the 'to' list are reachable. This exercises the

c27cc94fad approxidate: handle pending number for "specials"
The approxidate parser has a table of special keywords like
"yesterday", "noon", "pm", etc. Some of these, like "pm", do
the right thing if we've recently seen a number: "3pm" is
what you'd think.

However, most of them do not look at or modify the
pending-number flag at all, which means a number may "jump"
across a significant keyword and be used unexpectedly. For
example, when parsing:

  January 5th noon pm

we'd connect the "5" to "pm", and ignore it as a
day-of-month. This is obviously a bit silly, as "noon"
already implies "pm". And other mis-parsed things are
generally as silly ("January 5th noon, years ago" would
connect the 5 to "years", but probably nobody would type
that).

However, the fix is simple: when we see a keyword like
"noon", we should flush the pending number (as we would if
we hit another number, or the end of the string). In a few
of the specials that actually modify the day, we can simply
throw away the number (saying "Jan 5 yesterday" should not
respect the number at all).

Note that we have to either move or forward-declare the
static pending_number() to make it accessible to these
functions; this patch moves it.

b4cfcde4db rev-list: handle flags for --indexed-objects
When a traversal sees the --indexed-objects option, it adds
all blobs and valid cache-trees from the index to the
traversal using add_index_objects_to_pending(). But that
function totally ignores its flags parameter!

That means that doing:

  git rev-list --objects --indexed-objects

and

  git rev-list --objects --not --indexed-objects

produce the same output, because we ignore the UNINTERESTING
flag when walking the index in the second example.

Nobody noticed because this feature was added as a way for
tools like repack to increase their coverage of reachable
objects, meaning it would only be used like the first
example above.

But since it's user facing (and because the documentation
describes it "as if the objects are listed on the command
line"), we should make sure the negative case behaves
sensibly.

561b583749 t6012: make rev-list tests more interesting
As we are working to rewrite some of the revision-walk machinery,
there could easily be some interesting interactions between the
options that force topological constraints (--topo-order,
--date-order, and --author-date-order) along with specifying a
path.

Add extra tests to t6012-rev-list-simplify.sh to add coverage of
these interactions. To ensure interesting things occur, alter the
repo data shape to have different orders depending on topo-, date-,
or author-date-order.

When testing using GIT_TEST_COMMIT_GRAPH, this assists in covering
the new logic for topo-order walks using generation numbers. The
extra tests can be added indepently.

11aad46432 tests: optionally skip git rebase -p tests
The `--preserve-merges` mode of the `rebase` command is slated to be
deprecated soon, as the more powerful `--rebase-merges` mode is
available now, and the latter was designed with the express intent to
address the shortcomings of `--preserve-merges`' design (e.g. the
inability to reorder commits in an interactive rebase).

As such, we will eventually even remove the `--preserve-merges` support,
and along with it, its tests.

In preparation for this, and also to allow the Windows phase of our
automated tests to save some well-needed time when running the test
suite, this commit introduces a new prerequisite REBASE_P, which can be
forced to being unmet by setting the environment variable
`GIT_TEST_SKIP_REBASE_P` to any non-empty string.

5ee4ef8bda t3418: decouple test cases from a previous rebase -p test case
It is in general a good idea for regression test cases to be as
independent of each other as possible (with the one exception of an
initial `setup` test case, which is only a test case in Git's test suite
because it does not have a notion of a fixture or setup).

This patch addresses one particular instance of this principle being
violated: a few test cases in t3418-rebase-continue.sh depend on a side
effect of a test case that verifies a specific `rebase -p` behavior. The
later test cases should, however, still succeed even if the `rebase -p`
test case is skipped.

6c8fbae619 t3404: decouple some test cases from outcomes of previous test cases
Originally, the `--preserve-merges` option of the `git rebase` command
piggy-backed on top of the `--interactive` feature. For that reason, the
early test cases were added to the very same test script that contains
the `git rebase -i` tests: `t3404-rebase-interactive.sh`.

However, since c42abfe785 (rebase: introduce a dedicated backend for
--preserve-merges, 2018-05-28), the `--preserve-merges` feature got its
own backend, in preparation for converting the rest of the
`--interactive` code to built-in code, written in C rather than shell.

The reason why the `--preserve-merges` feature was not converted at the
same time is that we have something much better now: `--rebase-merges`.
That option intends to supersede `--preserve-merges`, and we will
probably deprecate the latter soon.

Once `--preserve-merges` has been deprecated for a good amount of time,
it will be time to remove it, and along with it, its tests.

In preparation for that, let's make the rest of the test cases in
`t3404-rebase-interactive.sh` independent of the test cases dedicated to
`--preserve-merges`.

5221048092 rev-parse: clear --exclude list after 'git rev-parse --all'
Commit [1] added the --exclude option to revision.c.  The --all,
--branches, --tags, --remotes, and --glob options clear the exclude
list.  Shortly therafter, commit [2] added the same to 'git rev-parse',
but without clearing the exclude list for the --all option.

5400b2a2d9 fetch-pack: be more precise in parsing v2 response
Each section in a protocol v2 response is followed by either a DELIM
packet (indicating more sections to follow) or a FLUSH packet
(indicating none to follow). But when parsing the "acknowledgments"
section, do_fetch_pack_v2() is liberal in accepting both, but determines
whether to continue reading or not based solely on the contents of the
"acknowledgments" section, not on whether DELIM or FLUSH was read.

There is no issue with a protocol-compliant server, but can result in
confusing error messages when communicating with a server that
serves unexpected additional sections. Consider a server that sends
"new-section" after "acknowledgments":

 - client writes request
 - client reads the "acknowledgments" section which contains no "ready",
   then DELIM
 - since there was no "ready", client needs to continue negotiation, and
   writes request
 - client reads "new-section", and reports to the end user "expected
   'acknowledgments', received 'new-section'"

For the person debugging the involved Git implementation(s), the error
message is confusing in that "new-section" was not received in response
to the latest request, but to the first one.

One solution is to always continue reading after DELIM, but in this
case, we can do better. We know from the protocol that "ready" means at
least the packfile section is coming (hence, DELIM) and that no "ready"
means that no sections are to follow (hence, FLUSH). So teach
process_acks() to enforce this.
