Test fixes.
* sg/test-must-be-empty:
tests: use 'test_must_be_empty' instead of 'test_cmp <empty> <out>'
tests: use 'test_must_be_empty' instead of 'test_cmp /dev/null <out>'
tests: use 'test_must_be_empty' instead of 'test ! -s'
tests: use 'test_must_be_empty' instead of '! test -s'
|
|
Using 'test_must_be_empty' is preferable to '! test -s', because it
gives a helpful error message if the given file is unexpectedly not
empty, while the latter remains completely silent. Furthermore, it
also catches cases when the given file unexpectedly does not exist at
all.
This patch was basically created by:
sed -i -e 's/! test -s/test_must_be_empty/' t[0-9]*.sh
with the following notable exceptions:
- The '! test -s' check in '.gitmodules ignore=dirty suppresses
submodules with untracked content' in 't7508-status.sh' is left
as-is, because it's bogus and, therefore, it's subject of a
dedicated patch.
- The '! test -s' checks in 't9131-git-svn-empty-symlink.sh' and
't9135-git-svn-moved-branch-empty-file.sh' are immediately
preceeded by a 'test -f' to ensure that the files exist in the
first place. 'test_must_be_empty' ensures that as well, so those
'test -f' commands are removed as well.

These are tests which are missing a link in their &&-chain,
but during a setup phase. We may fail to notice failure in
commands that build the test environment, but these are
typically not expected to fail at all (but it's still good
to double-check that our test environment is what we

Having a simulated "known breakage" test means that the test
suite will always tell us there is a bug to be fixed, even
though it is only simulated.
The right way to test this is in a sub-test, that can also
check that we provide the correct exit status and output.
Fortunately, we already have such a test (added much later
by 5ebf89e).
We could arguably get rid of the simulated success test
immediately above, as well, as it is also redundant with the
tests added in 5ebf89e. However, it does not have the
annoying behavior of the "known breakage" test. It may also
be easier to debug if the test suite is truly broken, since
it is not a test-within-a-test, as the later tests are.

Commit 517cd55 set HARNESS_ACTIVE unconditionally in
sub-tests, because that value affects the output of
"--verbose". t0000 needs stable output from its sub-tests,
and we may or may not be running under a TAP harness.
That commit made the decision to always set the variable,
since it has another useful side effect, which is
suppressing writes to t/test-results by the sub-tests (which
would just pollute the real results).
Since the last commit, though, the sub-tests have their own
test-results directories, so this is no longer an issue. We
can now update a few comments that are no longer accurate
nor necessary.
We can also revisit the choice of HARNESS_ACTIVE. Since we
must choose one value for stability, it's probably saner to
have it off. This means that future patches could test
things like the test-results writing, or the "--quiet"
option, which is currently ignored when run under a harness.

Running t0000 produces more trash directories than expected and does
not clean up after itself:
$ ./t0000-basic.sh
[...]
$ ls -d trash\ directory.*
trash directory.failing-cleanup
trash directory.mixed-results1
trash directory.mixed-results2
trash directory.partial-pass
trash directory.test-verbose
trash directory.test-verbose-only-2
These scratch areas for sub-tests should be under the t0000 trash
directory, but because TEST_OUTPUT_DIRECTORY defaults to
TEST_DIRECTORY, which is exported to help sub-tests find
test-lib.sh, the sub-test trash directories are created under the
toplevel t/ directory instead. Because some of the sub-tests
simulate failures, their trash directories are kept around.
Fix it by explicitly setting TEST_OUTPUT_DIRECTORY appropriately for
sub-tests.
An alternative fix would be to pass the --root parameter that only
specifies where to put the trash directories, which would also work.
However, using TEST_OUTPUT_DIRECTORY is more futureproof in case
tests want to write more output in addition to the test-results/
(which are already suppressed in sub-tests using the HARNESS_ACTIVE
setting) and trash directories.
This fixes a regression introduced by 38b074d (t/test-lib.sh: fix
TRASH_DIRECTORY handling, 2013-04-14). Before that commit, the
TEST_OUTPUT_DIRECTORY setting was not respected consistently so most
tests did their work in a "trash" subdirectory of the current
directory instead of the output dir.

Allows N instances of tests run in parallel, each running 1/N parts
of the test suite under Valgrind, to speed things up.
* tr/test-v-and-v-subtest-only:
perf-lib: fix start/stop of perf tests
test-lib: support running tests under valgrind in parallel
test-lib: allow prefixing a custom string before "ok N" etc.
test-lib: valgrind for only tests matching a pattern
test-lib: verbose mode for only tests matching a pattern
test-lib: self-test that --verbose works
test-lib: rearrange start/end of test_expect_* and test_skip
test-lib: refactor $GIT_SKIP_TESTS matching
test-lib: enable MALLOC_* for the actual tests
|
|
With the new --verbose-only=<pattern> option, one can enable --verbose
at a per-test granularity. The pattern is matched against the test
number, e.g.
./t0000-basic.sh --verbose-only='2[0-2]'
to see only the full output of test 20-22, while showing the rest in the
one-liner format.
As suggested by Jeff King, this takes care to wrap the entire
test_expect_* block, but nothing else, in the verbose toggling. We
can use the test_start/end functions from the previous commit for the
purpose.
This is arguably not *too* useful on its own, but makes the next patch
easier to follow.

t0000 contains some light self-tests of test-lib.sh, but --verbose was
not covered. Add a test.
The only catch is that the presence of a test harness influences the
output (specifically, the presence of some empty lines). So we need
to unset TEST_HARNESS or set it to a known value. Leaving it unset
leads to spurious test failures in the final summary, which come from
the subtest. So we always set it.

t0000-basic hard-codes many object IDs. To cater to file systems that do
not support symbolic links, different IDs are used depending on the
SYMLINKS prerequisite. But we can observe the symbolic links are only
needed to generate index entries. Use test_ln_s_add to generate the
index entries and get rid of explicit SYMLINKS checks.
This undoes the special casing introduced in this test by 704a3143

Change color of unexpectedly fixed known breakages to bold red. An
unexpectedly passing test indicates that the test code is somehow

You can set and test a prerequisite like this:
test_set_prereq FOO
test_have_prereq FOO && echo yes
You can negate the test in the shell like this:
! test_have_prereq && echo no
However, when you are using the automatic prerequisite
checking in test_expect_*, there is no opportunity to use
the shell negation. This patch introduces the syntax "!FOO"
to indicate that the test should only run if a prerequisite
is not meant.
One alternative is to set an explicit negative prerequisite,
like:
if system_has_foo; then
test_set_prereq FOO
else
test_set_prereq NO_FOO
fi
However, this doesn't work for lazy prerequisites, which
associate a single test with a single name. We could teach
the lazy prereq evaluator to set both forms, but the code
change ends up quite similar to this one (because we still
need to convert NO_FOO into FOO to find the correct lazy
script).

Match the style to more modern test scripts, namely:
- Prefer tabs for indentation.
- The first line of each test has prereq, title and opening sq for the
script body.
- Move cleanup or initialization of data used by a test inside the test
itself.
- Put a newline before the closing sq for each test.
- Don't conclude the test descriptions with a full stop.
- Prefer 'test_line_count = COUNT FILE' over 'test $(wc -l <FILE) = COUNT'
- Prefer 'test_line_count = 0 FILE' over 'cmp -s /dev/null FILE'
- Use '<<-EOF' style for here documents, so that they can be indented
as well. Bot don't do that in case the resulting lines would be too
long. Also when there is no $variable_substitution in the body of a
here document, quote \EOF.
- Don't redirect the output of commands to /dev/null unconditionally,
the git testing framework should already take care of handling test
verbosity transparently and uniformly.

t0000 contains two snippets of actual test output. This causes
problems when passing -v to the test[*]: the test infrastructure
echoes the tests before running them, and the TAP parser then sees
this test output and concludes that two tests failed and that the TAP
output was badly formatted.
Guard against this by quoting the output in the source.

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.

Change the passing TODO test in t0000-basic.sh to run inside its own

a normal test run for test smoking purposes.
If every normal test run has a passing TODO you're more likely to turn
a blind eye to it and not to investigate cases where things really are
passing unexpectedly.
It also makes the prove(1) output less noisy. Before:

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.

In 3bf7886 (test-lib: Let tests specify commands to be run at end of
test, 2010-05-02), the git test harness learned to run cleanup
commands unconditionally at the end of a test. During each test,
the intended cleanup actions are collected in the test_cleanup variable
and evaluated. That variable looks something like this:
eval_ret=$?; clean_something && (exit "$eval_ret")
eval_ret=$?; clean_something_else && (exit "$eval_ret")
eval_ret=$?; final_cleanup && (exit "$eval_ret")
eval_ret=$?
All cleanup actions are run unconditionally but if one of them fails
it is properly reported through $eval_ret.
On FreeBSD, unfortunately, $? is set at the beginning of an ‘eval’
to 0 instead of the exit status of the previous command. This results
in tests using test_expect_code appearing to fail and all others
appearing to pass, unless their cleanup fails. Avoid the problem by
setting eval_ret before the ‘eval’ begins.

Many tests depend on that symbolic links work. This introduces a check
that sets the prerequisite tag SYMLINKS if the file system supports
symbolic links. Since so many tests have to check for this prerequisite,
we do the check in test-lib.sh, so that we don't need to repeat the test
in many scripts.
To check for 'ln -s' failures, you can use a FAT partition on Linux:
$ mkdosfs -C git-on-fat 1000000
$ sudo mount -o loop,uid=j6t,gid=users,shortname=winnt git-on-fat /mnt
Clone git to /mnt and
$ GIT_SKIP_TESTS='t0001.1[34] t0010 t1301 t403[34] t4129.[47] t5701.7
t7701.3 t9100 t9101.26 t9119 t9124.[67] t9200.10 t9600.6' \

(These additionally skipped tests depend on POSIX permissions that FAT on
Linux does not provide.)

Some tests can be run only if a particular prerequisite is available. For
example, some tests require that an UTF-8 locale is available. Here we
introduce functions that are used in this way:
1. Insert code that checks whether the prerequisite is available. If it is,
call test_set_prereq with an arbitrary tag name that subsequently can be
used to check for the prerequisite:
case $LANG in
*.utf-8)
test_set_prereq UTF8
;;
esac
2. In the calls to test_expect_success pass the tag name:
test_expect_success UTF8 '...description...' '...tests...'
3. There is an auxiliary predicate that can be used anywhere to test for
a prerequisite explicitly:
if test_have_prereq UTF8
then
...code to be skipped if prerequisite is not available...

This fixes the remainder of the issues where the test script itself is at
fault for failing when the git checkout path contains whitespace or other
shell metacharacters.
The majority of git svn tests used the idiom
test_expect_success "title" "test script using $svnrepo"
These were changed to have the test script in single-quotes:
test_expect_success "title" 'test script using "$svnrepo"'
which unfortunately makes the patch appear larger than it really is.
One consequence of this change is that in the verbose test output the
value of $svnrepo (and in some cases other variables, too) is no
longer expanded, i.e. previously we saw
* expecting success:
test script using /path/to/git/t/trash/svnrepo

Originally, test_expect_failure was designed to be the opposite
of test_expect_success, but this was a bad decision. Most tests
run a series of commands that leads to the single command that
needs to be tested, like this:
test_expect_{success,failure} 'test title' '
setup1 &&
setup2 &&
setup3 &&
what is to be tested
'
And expecting a failure exit from the whole sequence misses the
point of writing tests. Your setup$N that are supposed to
succeed may have failed without even reaching what you are
trying to test. The only valid use of test_expect_failure is to
check a trivial single command that is expected to fail, which
is a minority in tests of Porcelain-ish commands.
This large-ish patch rewrites all uses of test_expect_failure to
use test_expect_success and rewrites the condition of what is
tested, like this:
test_expect_success 'test title' '
setup1 &&
setup2 &&
setup3 &&
! this command should fail
'
test_expect_failure is redefined to serve as a reminder that
that test *should* succeed but due to a known breakage in git it
currently does not pass. So if git-foo command should create a
file 'bar' but you discovered a bug that it doesn't, you can
write a test like this:
test_expect_failure 'git-foo should create bar' '
rm -f bar &&
git foo &&
test -f bar
'
This construct acts similar to test_expect_success, but instead
of reporting "ok/FAIL" like test_expect_success does, the
outcome is reported as "FIXED/still broken".

We currently use lower 12-bit (masked with CE_NAMEMASK) in the
ce_flags field to store the length of the name in cache_entry,
without checking the length parameter given to
create_ce_flags(). This can make us store incorrect length.
Currently we are mostly protected by the fact that many
codepaths first copy the path in a variable of size PATH_MAX,
which typically is 4096 that happens to match the limit, but
that feels like a bug waiting to happen. Besides, that would
not allow us to shorten the width of CE_NAMEMASK to use the bits
for new flags.
This redefines the meaning of the name length stored in the
cache_entry. A name that does not fit is represented by storing
CE_NAMEMASK in the field, and the actual length needs to be
computed by actually counting the bytes in the name[] field.
This way, only the unusually long paths need to suffer.

This patch adds convenience functions to work with absolute paths.
The function is_absolute_path() should help the efforts to integrate
the MinGW fork.
Note that make_absolute_path() returns a pointer to a static buffer.
