2024-11-21t: remove TEST_PASSES_SANITIZE_LEAK annotationsPatrick Steinhardt1-1/+0
Now that the default value for TEST_PASSES_SANITIZE_LEAK is `true` there is no longer a need to have that variable declared in all of our tests. Drop it. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2024-09-27diffcore-break: fix leaking filespecs when merging broken pairsPatrick Steinhardt1-0/+1
When merging file pairs after they have been broken up we queue a new file pair and discard the broken-up ones. The newly-queued file pair reuses one filespec of the broken up pairs each, where the respective other filespec gets discarded. But we only end up freeing the filespec's data, not the filespec itself, and thus leak memory. Fix these leaks by using `free_filespec()` instead.

2023-05-08t: drop "verbose" helper functionJeff King1-1/+1
We have a small helper function called "verbose", with the idea that you can write: verbose foo to get a message to stderr when the "foo" command fails, even if it does not produce any output itself. This goes back to 8ad1652418 (t5304: use helper to report failure of "test foo = bar", 2014-10-10). It does work, but overall it has not been a big success for two reasons: 1. Test writers have to remember to put it there (and the resulting test code is longer as a result). 2. It doesn't handle the opposite case (we expect "foo" to fail, but it succeeds), leading to inconsistencies in tests (which you can see in many hunks of this patch, e.g. ones involving "has_cr"). Most importantly, we added a136f6d8ff (test-lib.sh: support -x option for shell-tracing, 2014-10-10) at the same time, and it does roughly the same thing. The output is not quite as succinct as "verbose", and you have to watch out for stray shell-traces ending up in stderr. But it solves both of the problems above, and has clearly become the preferred tool. Let's consider the "verbose" function a failed experiment and remove the last few callers (which are all many years old, and have been dwindling as we remove them from scripts we touch for other reasons). It will be one less thing for new test writers to see and wonder if they should be using themselves. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-10-15tests: stop using top-level "README" and "COPYING" filesÆvar Arnfjörð Bjarmason1-2/+4
In 459b8d22e54 (tests: do not borrow from COPYING and README from the real source, 2015-02-15) tests that used "lib-diff.sh" (called "diff-lib.sh" then) were made to stop relying on the top-level COPYING file, but we still had other tests that referenced it. Let's move them over to use the "COPYING_test_data" utility function introduced in the preceding commit, and in the case of the one test that needed the "README" file use a ROT 13 version of that "COPYING" test data. That test added in afd222967c6 (Extend testing git-mv for renaming of subdirectories, 2006-07-26) just needs more test data that's not the same as the "COPYING" test data, so a ROT 13 version will do. This change removes the last references to ../{README,COPYING} in the test suite. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2015-03-20t: use verbose instead of hand-rolled errorsJeff King1-4/+1
Many tests that predate the "verbose" helper function use a pattern like: test ... || { echo ... false } to give more verbose output. Using the helper, we can do this with a single line, and avoid a || which interacts badly with &&-chaining (besides fooling --chain-lint, we hit the error block no matter which command in the chain failed, so we may often show useless results). In most cases, the messages printed by "verbose" are equally good (in some cases better; t6006 accidentally redirects the message to a file!). The exception is t7001, whose output suffers slightly. However, it's still enough to show the user which part failed, given that we will have just printed the test script to stderr.

2012-08-05Fix '\ No newline...' annotation in rewrite diffsAdam Butcher1-0/+30
When a file that ends with an incomplete line is expressed as a complete rewrite with the -B option, git diff incorrectly appends the incomplete line indicator "\ No newline at end of file" after such a line, rather than writing it on a line of its own (the output codepath for normal output without -B does not have this problem). Add a LF after the incomplete line before writing the "\ No newline ..." out to fix this. Add a couple of tests to confirm that the indicator comment is generated on its own line in both plain diff and rewrite mode.

2011-04-02git diff -D: omit the preimage of deletesJunio C Hamano1-1/+42
When reviewing a patch while concentrating primarily on the text after then change, wading through pages of deleted text involves a cognitive burden. Introduce the -D option that omits the preimage text from the patch output for deleted files. When used with -B (represent total rewrite as a single wholesale deletion followed by a single wholesale addition), the preimage text is also omitted. To prevent such a patch from being applied by mistake, the output is designed not to be usable by "git apply" (or GNU "patch"); it is strictly for human consumption. It of course is possible to "apply" such a patch by hand, as a human can read the intention out of such a patch. It however is impossible to apply such a patch even manually in reverse, as the whole point of this option is to omit the information necessary to do so from the output.

2008-08-17tests: use $TEST_DIRECTORY to refer to the t/ directoryJunio C Hamano1-2/+2
Many test scripts assumed that they will start in a 'trash' subdirectory that is a single level down from the t/ directory, and referred to their test vector files by asking for files like "../t9999/expect". This will break if we move the 'trash' subdirectory elsewhere. To solve this, we earlier introduced "$TEST_DIRECTORY" so that they can refer to t/ directory reliably. This finally makes all the tests use it to refer to the outside environment. With this patch, and a one-liner not included here (because it would contradict with what Dscho really wants to do): | diff --git a/t/test-lib.sh b/t/test-lib.sh | index 70ea7e0..60e69e4 100644 | --- a/t/test-lib.sh | +++ b/t/test-lib.sh | @@ -485,7 +485,7 @@ fi | . ../GIT-BUILD-OPTIONS | | # Test repository | -test="trash directory" | +test="trash directory/another level/yet another" | rm -fr "$test" || { | trap - exit | echo >&5 "FATAL: Cannot prepare test area" all the tests still pass, but we would want extra sets of eyeballs on this type of change to really make sure.

2008-03-12tr portability fixesJeff King1-1/+4
Specifying character ranges in tr differs between System V and POSIX. In System V, brackets are required (e.g., '[A-Z]'), whereas in POSIX they are not. We can mostly get around this by just using the bracket form for both sets, as in: tr '[A-Z] '[a-z]' in which case POSIX interpets this as "'[' becomes '['", which is OK. However, this doesn't work with multiple sequences, like: # rot13 tr '[A-Z][a-z]' '[N-Z][A-M][n-z][a-m]' where the POSIX version does not behave the same as the System V version. In this case, we must simply enumerate the sequence. This patch fixes problematic uses of tr in git scripts and test scripts in one of three ways: - if a single sequence, make sure it uses brackets - if multiple sequences, enumerate - if extra brackets (e.g., tr '[A]' 'a'), eliminate brackets Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
