2014-01-02t0000: drop "known breakage" testLibravatar Jeff King1-3/+0
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.

2014-01-02t0000: simplify HARNESS_ACTIVE hackLibravatar Jeff King1-9/+5
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.

2014-01-02t0000: set TEST_OUTPUT_DIRECTORY for sub-testsLibravatar Jeff King1-0/+2
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.

2013-06-23test-lib: verbose mode for only tests matching a patternLibravatar Thomas Rast1-0/+24
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.

2013-06-23test-lib: self-test that --verbose worksLibravatar Thomas Rast1-1/+36
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.

2013-06-07t0000: use test_ln_s_add to remove SYMLINKS prerequisiteLibravatar Johannes Sixt1-29/+10
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.

2012-11-15test-lib: allow negation of prerequisitesLibravatar Jeff King1-0/+32
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).

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.

2010-10-06test-lib: make test_expect_code a test commandLibravatar Ævar Arnfjörð Bjarmason1-10/+45
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 test-lib.sh. The motivation is to have nothing out of the ordinary on a normal test run for test smoking purposes.

2010-08-18test-lib: Multi-prereq support only checked the last prereqLibravatar Ævar Arnfjörð Bjarmason1-1/+5
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.

2010-05-06test-lib: some shells do not let $? propagate into an evalLibravatar Jonathan Nieder1-0/+21
In 3bf7886 (test-lib: Let tests specify commands to be run at end of test, 2010-05-02), the git test harness learned to run cleanup commands unconditionally at the end of a test. During each test, the intended cleanup actions are collected in the test_cleanup variable and evaluated. That variable looks something like this: eval_ret=$?; 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.

2009-03-22Use prerequisite tags to skip tests that depend on symbolic linksLibravatar Johannes Sixt1-12/+31
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' \ make test (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... fi Signed-off-by: Johannes Sixt <j6t@kdbg.org>

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 $svnrepo (and in some cases other variables, too) is no longer expanded, i.e. previously we saw * expecting success: test script using /path/to/git/t/trash/svnrepo but now it is: * expecting success: test script using "$svnrepo" Signed-off-by: Bryan Donlan <bdonlan@fushizen.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-02-01Sane use of test_expect_failureLibravatar Junio C Hamano1-9/+21
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. Signed-off-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-08-01Add is_absolute_path() and make_absolute_path()Libravatar Johannes Schindelin1-0/+16
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. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-07-02Rewrite "git-frotz" to "git frotz"Libravatar Junio C Hamano1-52/+52
This uses the remove-dashes target to replace "git-frotz" to "git frotz". Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-06-07War on whitespaceLibravatar Junio C Hamano1-1/+1
This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

2007-01-12use 'init' instead of 'init-db' for shipped docs and toolsLibravatar Nicolas Pitre1-2/+2
While 'init-db' still is and probably will always remain a valid git command for obvious backward compatibility reasons, it would be a good idea to move shipped tools and docs to using 'init' instead. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-12-17Fix check_file_directory_conflict().Libravatar Junio C Hamano1-0/+9
When replacing an existing file A with a directory A that has a file A/B in it in the index, 'update-index --replace --add A/B' did not properly remove the file to make room for the new directory. There was a trivial logic error, most likely a cut & paste one, dating back to quite early days of git. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-12-12Get rid of the dependency on RCS' merge programLibravatar Johannes Schindelin1-13/+1
Now that we have git-merge-file, an RCS merge lookalike, we no longer need it. So long, merge, and thanks for all the fish! Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-11-13Catch errors when writing an index that contains invalid objects.Libravatar Johannes Sixt1-0/+22
If git-write-index is called without --missing-ok, it reports invalid objects that it finds in the index. But without this patch it dies right away or may run into an infinite loop. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-05-01write-tree: --prefix=<path>Libravatar Junio C Hamano1-0/+14
The "bind" commit can express an aggregation of multiple projects into a single commit. In such an organization, there would be one project, root of whose tree object is at the same level of the root of the aggregated projects, and other projects have their toplevel in separate subdirectories. Let's call that root level project the "primary project", and call other ones just "subprojects". You would first read-tree the primary project, and then graft the subprojects under their appropriate location using read-tree --prefix=<subdir>/ repeatedly. To write out a tree object from such an index for a subproject, write-tree --prefix=<subdir>/ is used. Signed-off-by: Junio C Hamano <junkio@cox.net>
