95d9d5ec75 tests --valgrind: provide a mode without --track-origins
With --valgrind=memcheck-fast, the tests run under memcheck but
without the autodetected --track-origins.  If you just run valgrind to
see *if* there is any memory issue with your program, the extra
information is not needed, and it comes at a roughly 30% hit in
runtime.

While it is possible to achieve the same through GIT_VALGRIND_OPTIONS,
this should be more discoverable and hopefully encourage more users to
run their tests with valgrind.

952af3511c tests: parameterize --valgrind option
Running tests under helgrind and DRD recently proved useful in
tracking down thread interaction issues.  This can unfortunately not
be done through GIT_VALGRIND_OPTIONS because any tool other than
memcheck would complain about unknown options.

Let --valgrind take an optional parameter that describes the valgrind
tool to invoke.  The default mode is to run memcheck as before.

d24fbca7a5 Remove Git's support for smoke testing
I'm no longer running the Git smoke testing service at
smoke.git.nix.is due to Smolder being a fragile piece of software not
having time to follow through on making it easy for third parties to
run and submit their own smoke tests.

So remove the support in Git for sending smoke tests to
smoke.git.nix.is, it's still easy to modify the test suite to submit
smokes somewhere else.

This reverts the following commits:

    Revert "t/README: Add SMOKE_{COMMENT,TAGS}= to smoke_report target" -- e38efac87d
    Revert "t/README: Document the Smoke testing" -- d15e9ebc5c

c4d2539af7 test-lib: add the test_pause convenience function
Since 781f76b15 (test-lib: redirect stdin of tests) you can't simply put a
"bash &&" into a test for debugging purposes anymore. Instead you'll have
to use "bash <&6 >&3 2>&4".

As that invocation is not that easy to remember add the test_pause
convenience function. It invokes "$SHELL_PATH" to provide a sane shell
for the user.

This function also checks if the -v flag is given and will error out if
that is not the case instead of letting the test hang until ^D is pressed.

fb3340a6a7 test-lib: introduce test_line_count to measure files
Some tests check their output with code like the following:

	test "$(git ls-files -u B | wc -l)" -eq 3 || {
		echo "BAD: should have left stages for B"
		return 1
	}

The verbose failure condition is used because test, unlike
diff, does not print any useful information about the
nature of the failure when it fails.

Introduce a test_line_count function to help. If used like

	git ls-files -u B >output &&
	test_line_count -eq 3 output

it will produce output like

	test_line_count: line count for output !-eq 3
	100644 b023018cabc396e7692c70bbf5784a93d3f738ab 2	hi.c
	100644 45b983be36b73c0788dc9cbcb76cbb80fc7bb057 3	hi.c

on failure.

892e6f7ea6 test-lib: make test_expect_code a test command
Change test_expect_code to be a normal test command instead of a
top-level command.

As a top-level command it would fail in cases like:

    test_expect_code 1 'phoney' '
        foo && bar && (exit 1)
    '

Here the test might incorrectly succeed if "foo" or "bar" happened to
fail with exit status 1. Instead we now do:

    test_expect_success 'phoney' '
        foo && bar && test_expect_code 1 "(exit 1)"
    '

Which will only succeed if "foo" and "bar" return status 0, and "(exit
1)" returns status 1.  Note that test_expect_code has been made slightly
noisier, as it reports the exit code it receives even upon success.

Some test code in t0000-basic.sh relied on the old semantics of
test_expect_code to test the test_when_finished command. I've
converted that code to use an external test similar to the TODO test I
added in v1.7.3-rc0~2^2~3.

good. We'd rather skip tests using the three-arg prereq form to the

example under a disclaimer which explains that it's probably not a
good idea to use it.

c91cfd1916 tests: A SANITY test prereq for testing if we're root
Some tests depend on not being able to write to files after chmod
-w. This doesn't work when running the tests as root.

Change test-lib.sh to test if this works, and if so it sets a new
SANITY test prerequisite. The tests that use this previously failed
when run under root.

There was already a test for this in t3600-rm.sh, added by Junio C
Hamano in 2283645 in 2006. That check now uses the new SANITY
prerequisite.

Some of this was resurrected from the "Tests in Cygwin" thread in May

5099b99d25 test-lib: Adjust output to be valid TAP format
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)
      Failed test:  2
      TODO passed:   3
      Non-zero exit status: 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).

e4597aae65 run test suite without dashed git-commands in PATH
Only put bin-wrappers in the PATH (not GIT_EXEC_PATH), to emulate the
default installed user environment, and ensure all the programs run
correctly in such an environment.  This is now the default, although
it can be overridden with a --with-dashes test option when running
tests.
