9cbdd76e09 t6010 (merge-base): modernize style
Guard setup with test_expect_success, put the opening quote
starting each test on the same line as the test_expect_* invocation,
and combine related actions into single tests.

While at it:

 - use test_cmp instead of expr or test $foo = $bar, for more helpful
   output with -v when tests fail;

 - use test_commit for brevity.

df516fb558 t7600 (merge): do not launch gitk for --debug
Probably as a development aid, this test script runs gitk --all
to allow the driver to inspect history between tests when run
with --debug.  As a result, running all tests with --debug
requires closing a long series of gitk displays, one at a time.

Use git log --graph --oneline instead.  This way, the history is
available for viewing with "git show" but the test script finishes
without interaction.

Longer term, it would be nice to have an option to run a
user-specified command between tests.  This patch does not do
that.

4c0734578f t7600 (merge): modernize style
Guard setup commands with test_expect_success, so they are easier
to visually skip over and get to the good part.  While at it:

 - use "printf '%s\n' a b ..." instead of "cat <<EOF" for test
   vectors with short lines;

 - use test_cmp instead of test foo = bar where possible, for
   better output with -v on failure;

 - do not go to extraordinary lengths to print a relevant message
   when test commands fail.  There is a patch in flight that could be
   used to restore the nice error messages in a cleaner way.

0b9dca434f submodule sync: Update "submodule.<name>.url"
When "git submodule sync" synchronizes the repository URLs
it only updates submodules' .git/config.  However, the old
URLs still exist in the super-project's .git/config.

Update the super-project's configuration so that commands
such as "git submodule update" use the URLs from .gitmodules.

d0736f7b81 git-notes: Run partial expensive test everywhere
The git-notes expensive timing test is only expensive because it
either did 10,100,1k and 10k iterations or nothing.

Change it to do 10 by default, with an option to run the expensive
version with the old GIT_NOTES_TIMING_TESTS=ZomgYesPlease variable.

Since nobody was ostensibly running this test under TAP the code had
bitrotted so that it emitted invalid TAP. This change fixes that.

The old version would also mysteriously fail on systems without
/usr/bin/time, there's now a check for that using the multiple test
prerequisite facility.

99d9050d25 t/README: Update "Skipping tests" to align with best practices
The example I initially added to "Skipping tests" wasn't very
good. We'd rather skip tests using the three-arg prereq form to the
test_* functions, not bail out with a skip message.

Change the documentation to reflect that, but retain the bailout
example under a disclaimer which explains that it's probably not a
good idea to use it.

    Probably belongs in a separate patch.  More importantly, it is missing

4678a5cd71 t/Makefile: Can't include GIT-BUILD-OPTIONS, it's a .sh
Change the smoke testing portion of t/Makefile not to include
GIT-BUILD-OPTIONS. It's a shellscript, not a Makefile snippet, so it
had the nasty side-effect of sneaking e.g. SHELL_PATH = '/bin/sh'
(with quotes) everywhere.

Just add our own PERL_PATH variable as a workaround. The t/Makefile
already has e.g. an equivalent SHELL_PATH and TAR option which
duplicate the definitions in GIT-BUILD-OPTIONS.

d15e9ebc5c t/README: Document the Smoke testing
Git now has a smoke testing service at http://smoke.git.nix.is that
anyone can send reports to. Change the t/README file to mention this.

b6b84d1b74 tests: Infrastructure for Git smoke testing
Add the capability to send smoke reports from the Git test suite.

Currently we only notice bugs in the test suite when it's run
manually. Bugs in Git that only occur on obscure platforms or setups
that the core developers aren't using can thus go unnoticed.

This series aims to change that. With it, anyone that's interested in
avoiding bitrot in Git can volunteer to run a smoke tester. A smoke
tester periodically compiles the latest version of Git, runs the test
suite, and submits a report to a central server indicating how the
test run went.

A smoke tester might run something like this in cron:

    #!/bin/sh
    cd ~/g/git
    git fetch
    for branch in maint master next pu; do
        git checkout origin/$i &&
        make clean all &&
        cd t &&
        make smoke_report
    done

The smoker might want to compile git with non-default flags, include
bisecting functionality or run the tests under valgrind. Doing that is
outside the scope of this patch, this just adds a report submission
mechanism. But including a canonical smoke runner is something we'll
want to include eventually.

What this does now is add smoke and smoke_report targets to t/Makefile
(this example only uses a few tests for demonstration):

    $ make clean smoke
    rm -f -r 'trash directory'.* test-results
    rm -f t????/cvsroot/CVSROOT/?*
    rm -f -r valgrind/bin
    rm -f .prove
    perl ./harness --git-version="1.7.2.1.173.gc9b40" \
                    --no-verbose \
                    --archive="test-results/git-smoke.tar.gz" \
                    t0000-basic.sh t0001-init.sh t0002-gitfile.sh t0003-attributes.sh t0004-unwritable.sh t0005-signals.sh t0006-date.sh

    t0004-unwritable.sh .. ok
    t0005-signals.sh ..... ok

    All tests successful.

    TAP Archive created at /home/avar/g/git/t/test-results/git-smoke.tar.gz

The smoke target uses TAP::Harness::Archive to aggregate the test
results into a tarball. The tarball contains two things, the output of
every test file that was run, and a metadata file:

Tarball contents:

    $ tar xzvf git-smoke.tar.gz
    t0004-unwritable.sh
    t0001-init.sh
    t0002-gitfile.sh
    t0005-signals.sh
    t0000-basic.sh
    t0003-attributes.sh
    t0006-date.sh
    meta.yml

A test report:

    $ cat t0005-signals.sh
    ok 1 - sigchain works
    # passed all 1 test(s)
    1..1

A metadata file:

The "extra_properties" hash is where we'll stick Git-specific info,
like whether Git was compiled with gettext or the fallback regex
engine, and what branch we're compiling. Currently no metadata like
this is included.

The entire tarball is then submitted to a central smokebox at
smoke.git.nix.is. This is done with curl(1) via the "smoke_report"
target:

    $ make smoke_report
    curl \
                    -H "Expect: " \
                    -F project=Git \
                    -F architecture=x86_64 \
                    -F platform=Linux \
                    -F revision="1.7.2.1.173.gc9b40" \
                    -F report_file=@test-results/git-smoke.tar.gz \
                    http://smoke.git.nix.is/app/projects/process_add_report/1 \
            | grep -v ^Redirecting
      % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

    Reported #8 added.

Reports are then made available on the smokebox via a web interface:

    http://smoke.git.nix.is/app/projects/smoke_reports/1

The smoke reports are also mirrored to a Git repository hosted on
GitHub:

    http://github.com/gitsmoke/smoke-reports

The Smolder SQLite database that contains metadata about the reports
is also made available:

    http://github.com/gitsmoke/smoke-database

ce60653e59 test-lib: Multi-prereq support only checked the last prereq
The support for multiple test prerequisites added by me in "test-lib:
Add support for multiple test prerequisites" was broken.

The for iterated over each prerequisite and returned true/false within
a case statement, but since it missed a return statement only the last
prerequisite in the list of prerequisites was ever considered, the
rest were ignored.

Fix that by changing the test_have_prereq code to something less
clever that keeps a count of the total prereqs and the ones we have
and compares the count at the end.

This comes with the added advantage that it's easy to list the missing
prerequisites in the test output, implement that while I'm at 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
2009:
