This commit fixes one test in t3508 by making "cherry-pick -<num>"
walk the history.
A test update from Elijah Newren is squashed as an evil merge.
This test is accessing private object members of the Test::More and
Test::Builder objects. Older versions of Test::More did not implement
these variables using a hash.
My system complains as follows:
Can't coerce array into hash at <snip>/t/t9700/test.pl line 13.

There are public access methods available for retrieving and setting these
variables, so let's use them instead.

When git is passed the --paginate option, starting up a pager requires
deciding what pager to start, which requires access to the core.pager
configuration.
At the relevant moment, the repository has not been searched for yet.
Attempting to access the configuration at this point results in
git_dir being set to .git [*], which is almost certainly not what was
wanted. In particular, when run from a subdirectory of the toplevel,
git --paginate does not respect the core.pager setting from the
current repository.
[*] unless GIT_DIR or GIT_CONFIG is set
So delay the pager startup when possible:
1. run_argv() already commits pager choice inside run_builtin() if a
command is found. For commands that use RUN_SETUP, waiting until
then fixes the problem described above: once git knows where to
look, it happily respects the core.pager setting.
2. list_common_cmds_help() prints out 29 lines and exits. This can
benefit from pagination, so we need to commit the pager choice
before writing this output.
Luckily ‘git’ without subcommand has no other reason to access a
repository, so it would be intuitive to ignore repository-local
configuration in this case. Simpler for now to choose a pager
using the funny code that notices a repository that happens to be
at .git. That this accesses a repository when it is very
convenient to is a bug but not an important one.
3. help_unknown_cmd() prints out a few lines to stderr. It is not
important to paginate this, so don’t.

In other words, with --paginate and only with --paginate, any

$Test::Builder::Test was only made into an `our' variable in 0.94
released in September 2009, older distros are more likely to have 0.92

The exit() call was also unportable to <0.94. Just output a meaningful

In some use cases it is not desirable that "git status" considers
submodules that only contain untracked content as dirty. This may happen
e.g. when the submodule is not under the developers control and not all
build generated files have been added to .gitignore by the upstream
developers. Using the "untracked" parameter for the "--ignore-submodules"
option disables checking for untracked content and lets git diff report
them as changed only when they have new commits or modified content.
Sometimes it is not wanted to have submodules show up as changed when they
just contain changes to their work tree (this was the behavior before
1.7.0). An example for that are scripts which just want to check for
submodule commits while ignoring any changes to the work tree. Also users
having large submodules known not to change might want to use this option,
as the - sometimes substantial - time it takes to scan the submodule work
tree(s) is saved when using the "dirty" parameter.
And if you want to ignore any changes to submodules, you can now do that
by using this option without parameters or with "all" (when the config
option status.submodulesummary is set, using "all" will also suppress the
output of the submodule summary).
A new function handle_ignore_submodules_arg() is introduced to parse this
option new to "git status" in a single location, as "git diff" already
knew it.

SKIP messages are now part of the TAP plan. A TAP harness now knows

Some tests in the testsuite will emit a line that doesn't end with a
newline, right before we're about to output "ok" or "not ok". This
breaks the TAP output with "Tests out of sequence" errors since a TAP
harness can't understand this:
ok 1 - A test
[some output here]ok 2 - Another test
ok 3 - Yet another test
Work around it by emitting an empty line before we're about to say
"ok" or "not ok", but only if we're running under --verbose and
HARNESS_ACTIVE=1 is set, which'll only be the case when running under
a harnesses like prove(1).
I think it's better to do this than fix each tests by adding `&& echo'
everywhere. More tests might be added that break TAP in the future,
and a human isn't going to look at the extra whitespace, since
HARNESS_ACTIVE=1 always means a harness is reading it.
The tests that had issues were:
t1007, t3410, t3413, t3409, t3414, t3415, t3416, t3412, t3404,
t5407, t7402, t7003, t9001

Before TAP we just ran the Perl test and assumed that it failed if
nothing was printed on STDERR. Continue doing that, but introduce a
`test_external_has_tap' variable which tests can set to indicate that
they're outputting TAP.
If it's set we won't output a test plan, but trust the external test
to do so. That way we can make external tests work with a TAP harness,
but still maintain compatibility with test-lib's own way of tracking
tests through the test-results directory.

TAP, the Test Anything Protocol, is a simple text-based interface
between testing modules in a test harness. test-lib.sh's output was
already very close to being valid TAP. This change brings it all the
way there. Before:
$ ./t0005-signals.sh
* ok 1: sigchain works
* passed all 1 test(s)
And after:
$ ./t0005-signals.sh
ok 1 - sigchain works
# passed all 1 test(s)
1..1
The advantage of using TAP is that any program that reads the format
(a "test harness") can run the tests. The most popular of these is the
prove(1) utility that comes with Perl. It can run tests in parallel,
display colored output, format the output to console, file, HTML etc.,
and much more. An example:
$ prove ./t0005-signals.sh
./t0005-signals.sh .. ok
All tests successful.
Files=1, Tests=1, 0 wallclock secs ( 0.03 usr 0.00 sys + 0.01 cusr 0.02 csys = 0.06 CPU)
Result: PASS
prove(1) gives you human readable output without being too
verbose. Running the test suite in parallel with `make test -j15`
produces a flood of text. Running them with `prove -j 15 ./t[0-9]*.sh`
makes it easy to follow what's going on.
All this patch does is re-arrange the output a bit so that it conforms
with the TAP spec, everything that the test suite did before continues
to work. That includes aggregating results in t/test-results/, the
--verbose, --debug and other options for tests, and the test color
output.
TAP harnesses ignore everything that they don't know about, so running
the tests with --verbose works:
$ prove ./t0005-signals.sh :: --verbose --debug
./t0005-signals.sh .. Terminated
./t0005-signals.sh .. ok
All tests successful.
Files=1, Tests=1, 0 wallclock secs ( 0.02 usr 0.01 sys + 0.01 cusr 0.01 csys = 0.05 CPU)
Result: PASS
Just supply the -v option to prove itself to get all the verbose
output that it suppresses:
$ prove -v ./t0005-signals.sh :: --verbose --debug
./t0005-signals.sh ..
Initialized empty Git repository in /home/avar/g/git/t/trash directory.t0005-signals/.git/
expecting success:
test-sigchain >actual
case "$?" in
143) true ;; # POSIX w/ SIGTERM=15
3) true ;; # Windows
*) false ;;
esac &&
test_cmp expect actual
Terminated
ok 1 - sigchain works
# passed all 1 test(s)
1..1
ok
All tests successful.
Files=1, Tests=1, 0 wallclock secs ( 0.02 usr 0.00 sys + 0.01 cusr 0.01 csys = 0.04 CPU)
Result: PASS
As a further example, consider this test script that uses a lot of
test-lib.sh features by Jakub Narebski:
#!/bin/sh
test_description='this is a sample test.
This test is here to see various test outputs.'
. ./test-lib.sh
say 'diagnostic message'
test_expect_success 'true test' 'true'
test_expect_success 'false test' 'false'
test_expect_failure 'true test (todo)' 'true'
test_expect_failure 'false test (todo)' 'false'
test_debug 'echo "debug message"'
test_done
The output of that was previously:
* diagnostic message # yellow
* ok 1: true test
* FAIL 2: false test # bold red
false
* FIXED 3: true test (todo)
* still broken 4: false test (todo) # bold green
* fixed 1 known breakage(s) # green
* still have 1 known breakage(s) # bold red
* failed 1 among remaining 3 test(s) # bold red
But is now:
diagnostic message # yellow
ok 1 - true test
not ok - 2 false test # bold red
# false
ok 3 - true test (todo) # TODO known breakage
not ok 4 - false test (todo) # TODO known breakage # bold green
# fixed 1 known breakage(s) # green
# still have 1 known breakage(s) # bold red
# failed 1 among remaining 3 test(s) # bold red
1..4
All the coloring is preserved when the test is run manually. Under
prove(1) the test performs as expected, even with --debug and
--verbose options:
$ prove ./example.sh :: --debug --verbose
./example.sh .. Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/4 subtests
(1 TODO test unexpectedly succeeded)
Test Summary Report
-------------------
./example.sh (Wstat: 256 Tests: 4 Failed: 1)

Files=1, Tests=4, 0 wallclock secs ( 0.02 usr 0.00 sys + 0.00 cusr 0.01 csys = 0.03 CPU)
Result: FAIL
The TAP harness itself doesn't get confused by the color output, they
aren't used by test-lib.sh stdout isn't open to a terminal (test -t 1).

The fake "less" script was already created in a previous test titled
'setup: fake "less"', so it is redundant. Additionally, it is broken since
the redirection of 'cat' is to a file named 'less', but the chmod operates
on the file named by the $less variable which may not contain the value
'less'.

The fake "less" script was not being made executable. This can cause the
tests that follow to fail. This failure is not apparent on platforms which
have DEFAULT_PAGER set to the string "less", since lib-pager.sh will have
set the $less variable to "less" and the SIMPLEPAGER prerequisite will have
been set, and so the "less" script will have already been created properly
and made executable in test 2 'git grep -O'. On platforms which set
DEFAULT_PAGER to something like "more", no such script will have been
previously created, and tests 7 and 8 will fail.
So, add a call to chmod to make the fake "less" script executable.

Regular expressions matched by 'expr' have an implicit '^' at the beginning
of them and so are anchored to the beginning of the string. Using the '^'

'^'. Additionally, GNU expr 5.97 complains like this:
