Jeff King	d391c0ff94	diff: don't use pathname-based diff drivers for symlinks When we're diffing symlinks, we consider the contents to be the pathname that the symlink points to. When a user sets up a userdiff driver like ".pdf diff=pdf", their "diff.pdf." config generally tells us what to do with the content of pdf files. With the current code, we will actually process a symlink like "link.pdf" using a configured pdf driver, meaning we are using contents which consist of a pathname with configuration that is expecting contents that consist of an actual pdf file. The most noticeable example of this would have been textconv; however, it was already protected in its own textconv-specific code path. We can still see the breakage with something like "diff..binary", though. You could also see it with diff..funcname, though it is a bit harder to trigger accidentally there. This patch adds a check for S_ISREG lower in the callstack than the textconv-specific check, which should block use of any userdiff config for non-regular files. We can drop the check in the textconv code, which is now redundant. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago
Ævar Arnfjörð Bjarmason	41be8ea223	tests: implicitly skip SYMLINKS tests using <prereq> Change the tests that skipped due to unavailable SYMLINKS support to use the three-arg prereq form of test_expect_success. Now we get an indication of how many tests that need symlinks are being skipped on platforms that don't support them.

Ævar Arnfjörð Bjarmason	fadb5156e4	tests: Skip tests in a way that makes sense under TAP SKIP messages are now part of the TAP plan. A TAP harness now knows why a particular test was skipped and can report that information. The non-TAP harness built into Git's test-lib did nothing special with these messages, and is unaffected by these changes.

Junio C Hamano	016e5ff243	war on "sleep" in tests In many places in test suite we have "sleep"s that do not have to be there. - I do not simply see the point of the one in t3500. It may be making sure that the timestamp order of commits generated during the test is stable, in which case test_tick is the right ingredient to use without wasting tester's time. - The one in t4011 is to make sure that the plumbing diff-index notices the stat-dirtyness of a removed then identically recreated symlink. Keeping the old symlink around to make sure that a newly created symlink gets different ino would be sufficient for that purpose. - The one in t7600 is to make sure that "git merge" does not get confused by stat-dirty "file" in the working tree. Again, keeping the old file around and creating an identical copy to ensure a different ino would be sufficient for that purpose. The "racy git" tests in t0010 are inherently about mtime between the index itself and index entries. The "sleep" in that test must stay as they are.

Johannes Sixt	704a3143d5	Use prerequisite tags to skip tests that depend on symbolic links 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.)

Johannes Schindelin	418566b6fd	Fix 'git diff --no-index' with a non-existing symlink target When trying to find out mode changes, we should not access the symlink targets using stat(); instead we use lstat() so that the diff does not fail trying to find a non-existing symlink target.

Junio C Hamano	bfdbee9810	tests: use $TEST_DIRECTORY to refer to the t/ directory Many test scripts assumed that they will start in a 'trash' subdirectory that is a single level down from the t/ directory, and referred to their test vector files by asking for files like "../t9999/expect". This will break if we move the 'trash' subdirectory elsewhere. To solve this, we earlier introduced "$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.

Junio C Hamano	5be60078c9	Rewrite "git-frotz" to "git frotz" This uses the remove-dashes target to replace "git-frotz" to "git frotz". Signed-off-by: Junio C Hamano <gitster@pobox.com>	18 years ago
Junio C Hamano	5df9140c92	t4011: "sleep 1" is not enough on FAT This test depended on "sleep 1" to be enough to dirty the index entry for a symlink. Alex noticed that on his Cygwin installation "sleep 1" was sometimes not enough, and after further discussion with Christopher Faylor, it was brought up that on FAT filesystem timestamp granularity is 2 seconds so sleeping 1 second is not enough. For now this patch takes an easy workaround of sleeping for 3 seconds. Very strictly speaking, POSIX requires lstat to fill only S_IFMT part of st_mode and st_size for symlinks, and depending on timestamp might be considered a bug, but we depend on that anyway, so it is better to test that.

Johannes Schindelin	975b31dc6e	Handle symlinks graciously This patch converts a stat() to an lstat() call, thereby fixing the case when the date of a symlink was not the same as the one recorded in the index. The included test case demonstrates this. This is for the case that the symlink points to a non-existing file. If the file exists, worse things than just an error message happen.
