* Merge branch 'lf/echo-n-is-not-portable'Junio C Hamano2013-08-01
|\ | | | | | | | | * lf/echo-n-is-not-portable: Avoid using `echo -n` anywhere
| * Avoid using `echo -n` anywhereLukas Fleischer2013-07-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | `echo -n` is non-portable. The POSIX specification says: Conforming applications that wish to do prompting without <newline> characters or that could possibly be expecting to echo a -n, should use the printf utility derived from the Ninth Edition system. Since all of the affected shell scripts use a POSIX shell shebang, replace `echo -n` invocations with printf.

* | perf-lib: fix start/stop of perf testsThomas Gummerer2013-06-29
|/ | | | | | | | | | | | ae75342 test-lib: rearrange start/end of test_expect_* and test_skip changed the way tests are started/stopped, but did not update the perf tests. They were therefore giving the wrong output, because of the wrong test count. Fix this by starting and stopping the tests correctly.

* MALLOC_CHECK: enable it, unless disabled explicitlyRené Scharfe2012-09-26
| | | | | | | | | | | The malloc checks in tests are currently disabled. Actually evaluate the variable for turning them off and enable them if it's unset. Also use this opportunity to give it the more descriptive and consistent name TEST_NO_MALLOC_CHECK.

* MALLOC_CHECK: various clean-upsJunio C Hamano2012-09-17
| | | | | | | | | | The most important in this change is to avoid affecting anything when test-lib is used from perf-lib. It also limits the effect of the MALLOC_CHECK only to what is run inside the actual test, and uses a fixed MALLOC_PERTURB_ in order to avoid hurting repeatability of the tests.

* tests: Introduce test_seqMichał Kiedrowicz2012-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jeff King wrote: The seq command is GNU-ism, and is missing at least in older BSD releases and their derivatives, not to mention antique commercial Unixes. We already purged it in b3431bc (Don't use seq in tests, not everyone has it, 2007-05-02), but a few new instances have crept in. They went unnoticed because they are in scripts that are not run by default. Replace them with test_seq that is implemented with a Perl snippet (proposed by Jeff). This is better than inlining this snippet everywhere it's needed because it's easier to read and it's easier to change the implementation (e.g. to C) if we ever decide to remove Perl from the test suite. Note that test_seq is not a complete replacement for seq(1). It just has what we need now, in addition that it makes it possible for us to do something like "test_seq a m" if we wanted to in the future. There are also many places that do `for i in 1 2 3 ...` but I'm not sure if it's worth converting them to test_seq. That would introduce running more processes of Perl.

* perf: export some important test-lib variablesThomas Rast2012-03-08
| | | | | | | | | | | | | | | | | The only bug right now is that $GIT_TEST_CMP is needed for test_cmp to work. However, we also export the three most important paths for tests: TEST_DIRECTORY TRASH_DIRECTORY GIT_BUILD_DIR Since they are available within test_expect_success, a future test writer may expect them to also be defined in test_perf.

* Introduce a performance testing frameworkThomas Rast2012-02-17
This introduces a performance testing framework under t/perf/. It tries to be as close to the test-lib.sh infrastructure as possible, and thus should be easy to get used to for git developers. The following points were considered for the implementation: 1. You usually want to compare arbitrary revisions/build trees against each other. They may not have the performance test under consideration, or even the perf-lib.sh infrastructure. To cope with this, the 'run' script lets you specify arbitrary build dirs and revisions. It even automatically builds the revisions if it doesn't have them at hand yet. 2. Usually you would not want to run all tests. It would take too long anyway. The 'run' script lets you specify which tests to run; or you can also do it manually. There is a Makefile for discoverability and 'make clean', but it is not meant for real-world use. 3. Creating test repos from scratch in every test is extremely time-consuming, and shipping or downloading such large/weird repos is out of the question. We leave this decision to the user. Two different sizes of test repos can be configured, and the scripts just copy one or more of those (using hardlinks for the object store). By default it tries to use the build tree's git.git repository. This is fairly fast and versatile. Using a copy instead of a clone preserves many properties that the user may want to test for, such as lots of loose objects, unpacked refs, etc. Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
