Currently when using --color-moved=zebra the color of moved blocks
depends on the number of lines separating them. This means that adding
an odd number of unmoved lines between blocks that are already separated
by one or more unmoved lines will change the color of subsequent moved
blocks. This does not make much sense as the blocks were already
separated by unmoved lines and causes problems when adding lines to test
cases.
Fix this by only using the alternate colors for adjacent moved blocks.

'diff --color-moved-ws=allow-indentation-change' can color lines as
moved when they are in fact different. For example in commit
1a07e59c3e ("Update messages in preparation for i18n", 2018-07-21) the
lines
- die (_("must end with a color"));
+ die(_("must end with a color"));
are colored as moved even though they are different.
This is because if there is a fuzzy match for the first line of
a potential moved block the line is marked as moved before the
potential match is checked to see if it actually matches. The fix is
to delay marking the line as moved until after we have checked that
there really is at least one matching potential moved block.
Note that the test modified in the last commit still fails because
adding an unmoved line between two moved blocks that are already
separated by unmoved lines changes the color of the block following the
addition. This should not be the case and will be fixed in the next
commit.

The loose objects cache is filled one subdirectory at a time as needed.
It is stored in an oid_array, which has to be resorted after each add
operation. So when querying a wide range of objects, the partially
filled array needs to be resorted up to 255 times, which takes over 100
times longer than sorting once.
Use one oid_array for each subdirectory. This ensures that entries have
to only be sorted a single time. It also avoids eight binary search
steps for each cache lookup as a small bonus.
The cache is used for collision checks for the log placeholders %h, %t
and %p, and we can see the change speeding them up in a repository with
ca. 100 objects per subdirectory:

As part of an ongoing effort to make rebase have more uniform behavior,
modify the merge backend to behave like the interactive one, by
re-implementing it on top of the latter.
Interactive rebases are implemented in terms of cherry-pick rather than
the merge-recursive builtin, but cherry-pick also calls into the
recursive merge machinery by default and can accept special merge
strategies and/or special strategy options. As such, there really is
not any need for having both git-rebase--merge and
git-rebase--interactive anymore. Delete git-rebase--merge.sh and
instead implement it in builtin/rebase.c.
This results in a few deliberate but small user-visible changes:
* The progress output is modified (see t3406 and t3420 for examples)
* A few known test failures are now fixed (see t3421)
* bash-prompt during a rebase --merge is now REBASE-i instead of
REBASE-m. Reason: The prompt is a reflection of the backend in use;
this allows users to report an issue to the git mailing list with
the appropriate backend information, and allows advanced users to
know where to search for relevant control files. (see t9903)
testcase modification notes:
t3406: --interactive and --merge had slightly different progress output
while running; adjust a test to match the new expectation
t3420: these test precise output while running, but rebase--am,
rebase--merge, and rebase--interactive all were built on very
different commands (am, merge-recursive, cherry-pick), so the
tests expected different output for each type. Now we expect
--merge and --interactive to have the same output.
t3421: --interactive fixes some bugs in --merge! Wahoo!
t9903: --merge uses the interactive backend so the prompt expected is
now REBASE-i.

Uninitialized submodules have nothing valueable for us to be worried
about. They are just SHA-1. Let "worktree remove" and "worktree move"
continue in this case so that people can still use multiple worktrees
on repos with optional submodules that are never populated, like
sha1collisiondetection in git.git when checked out by doc-diff script.
Note that for "worktree remove", it is possible that a user
initializes a submodule (*), makes some commits (but not push), then
deinitializes it. At that point, the submodule is unpopulated, but the
precious new commits are still in
$GIT_COMMON_DIR/worktrees/<worktree>/modules/<submodule>
directory and we should not allow removing the worktree or we lose
those commits forever. The new directory check is added to prevent
this.
(*) yes they are screwed anyway by doing this since "git submodule"
would add submodule.* in $GIT_COMMON_DIR/config, which is shared
across multiple worktrees. But it does not mean we let them be
screwed even more.

Unfortunately, we have a few flaky tests, whose failures tend to be
hard to reproduce. We've found that the best we can do to reproduce
such a failure is to run the test script repeatedly while the machine
is under load, and wait in the hope that the load creates enough
variance in the timing of the test's commands that a failure is
evenually triggered. I have a command to do that, and I noticed that
two other contributors have rolled their own scripts to do the same,
all choosing slightly different approaches.
To help reproduce failures in flaky tests, introduce the '--stress'
option to run a test script repeatedly in multiple parallel jobs until
one of them fails, thereby using the test script itself to increase
the load on the machine.
The number of parallel jobs is determined by, in order of precedence:
the number specified as '--stress=<N>', or the value of the
GIT_TEST_STRESS_LOAD environment variable, or twice the number of
available processors (as reported by the 'getconf' utility), or 8.
Make '--stress' imply '--verbose -x --immediate' to get the most
information about rare failures; there is really no point in spending
all the extra effort to reproduce such a failure, and then not know
which command failed and why.
To prevent the several parallel invocations of the same test from
interfering with each other:
- Include the parallel job's number in the name of the trash
directory and the various output files under 't/test-results/' as
a '.stress-<Nr>' suffix.
- Add the parallel job's number to the port number specified by the
user or to the test number, so even tests involving daemons
listening on a TCP socket can be stressed.
- Redirect each parallel test run's verbose output to
't/test-results/$TEST_NAME.stress-<nr>.out', because dumping the
output of several parallel running tests to the terminal would
create a big ugly mess.
For convenience, print the output of the failed test job at the end,
and rename its trash directory to end with the '.stress-failed'
suffix, so it's easy to find in a predictable path (OTOH, all absolute
paths recorded in the trash directory become invalid; we'll see
whether this causes any issues in practice). If, in an unlikely case,
more than one jobs were to fail nearly at the same time, then print
the output of all failed jobs, and rename the trash directory of only
the last one (i.e. with the highest job number), as it is the trash
directory of the test whose output will be at the bottom of the user's
terminal.
Based on Jeff King's 'stress' script.

Several test scripts run daemons like 'git-daemon' or Apache, and
communicate with them through TCP sockets. To have unique ports where
these daemons are accessible, the ports are usually the number of the
corresponding test scripts, unless the user overrides them via
environment variables, and thus all those tests and test libs contain
more or less the same bit of one-liner boilerplate code to find out
the port. The last patch in this series will make this a bit more
complicated.
Factor out finding the port for a daemon into the common helper
function 'test_set_port' to avoid repeating ourselves.
Take special care of test scripts with "low" numbers:
- Test numbers below 1024 would result in a port that's only usable
as root, so set their port to '10000 + test-nr' to make sure it
doesn't interfere with other tests in the test suite. This makes
the hardcoded port number in 't0410-partial-clone.sh' unnecessary,
remove it.
- The shell's arithmetic evaluation interprets numbers with leading
zeros as octal values, which means that test number below 1000 and
containing the digits 8 or 9 will trigger an error. Remove all
leading zeros from the test numbers to prevent this.
Note that the 'git p4' tests are unlike the other tests involving
daemons in that:
- 'lib-git-p4.sh' doesn't use the test's number for unique port as
is, but does a bit of additional arithmetic on top [1].
- The port is not overridable via an environment variable.
With this patch even 'git p4' tests will use the test's number as
default port, and it will be overridable via the P4DPORT environment
variable.
[1] Commit fc00233071 (git-p4 tests: refactor and cleanup, 2011-08-22)
introduced that "unusual" unique port computation without
explaining why it was necessary (as opposed to simply using the
test number as is). It seems to be just unnecessary complication,
and in any case that commit came way before the "test nr as unique
port" got "standardized" for other daemons in commits c44132fcf3
(tests: auto-set git-daemon port, 2014-02-10), 3bb486e439 (tests:
auto-set LIB_HTTPD_PORT from test name, 2014-02-10), and

'test-lib.sh' looks for the presence of certain options like '--tee'
and '--verbose-log', so it can execute the test script again to save
its standard output and error. It looks for '--valgrind' as well, to
set up some Valgrind-specific stuff. These all happen before the
actual option parsing loop, and the conditions looking for these
options look a bit odd, too. They are not completely correct, either,
because in a bogus invocation like './t1234-foo.sh -r --tee' they
recognize '--tee', although it should be handled as the required
argument of the '-r' option. This patch series will add two more
options to look out for early, and, in addition, will have to extract
these options' stuck arguments (i.e. '--opt=arg') as well.
So let's move the option parsing loop and the couple of related
conditions following it earlier in 'test-lib.sh', before the place
where the test script is executed again for '--tee' and its friends.

'test-lib.sh' looks for the presence of certain options like '--tee'
and '--verbose-log', so it can execute the test script again to save
its standard output and error, and to do so it needs the original
command line options the test was invoked with.
The next patch is about to move the option parsing loop earlier in
'test-lib.sh', but it is implemented using 'shift' in a while loop,
effecively destroying "$@" by the end of the option parsing. Not
good.
As a preparatory step, turn that option parsing loop into a 'for opt
in "$@"' loop to preserve "$@" intact while iterating over the
options, and taking extra care to handle the '-r' option's required
argument (or the lack thereof).

801fa63a90 ("config.mak.dev: add -Wformat-security", 2018-09-08)
added the "-Wformat-security" to the flags set in config.mak.dev.
In the gcc man page this is documented as:
If -Wformat is specified, also warn about uses of format
functions that represent possible security problems. [...]
The commit did however not add the "-Wformat" flag, but instead
relied on the fact that "-Wall" is set in the Makefile by default
and that "-Wformat" is part of "-Wall".
Unfortunately, those who use config.mak.autogen generated with the
autoconf to configure toolchain do *not* get "-Wall" in their CFLAGS
and the added -Wformat-security had no effect. Worse yet, newer
versions of gcc (gcc 8.2.1 in this particular case) warn about the
lack of "-Wformat" and thus compilation fails only with this option
set.
We could fix it by adding "-Wformat", but in general we do want all
checks included in "-Wall", so let's add it to config.mak.dev to
cover more cases.

Right now if a test script receives SIGTERM or SIGHUP (e.g., because a
test was hanging and the user 'kill'-ed it or simply closed the
terminal window the test was running in), the shell exits immediately.
This can be annoying if the test script did any global setup, like
starting apache or git-daemon, as it will not have an opportunity to
clean up after itself. A subsequent run of the test won't be able to
start its own daemon, and will either fail or skip the tests.
Instead, let's trap SIGTERM and SIGHUP as well to make sure we do a
clean shutdown, and just chain it to a normal exit (which will trigger
any cleanup).
