Linus Torvalds	0940e5f211	diffcore-rename: properly honor the difference between -M and -C We would allow rename detection to do copy detection even when asked purely for renames. That confuses users, but more importantly it can terminally confuse the recursive merge rename logic.

Ævar Arnfjörð Bjarmason	f6c1998f14	t/t4004-diff-rename-symlink.sh: use three-arg <prereq> Change the tests that skipped due to unavailable SYMLINKS support to use the three-arg prereq form of test_expect_success. This is like the "tests: implicitly skip SYMLINKS tests using <prereq>" change, but I needed to create an additional test for some setup code. It's in a separate change as suggested by Jonathan Nieder for ease of reviewing.

More importantly, it is missing &&-chaining (not a regression, but it is best to set a good example).

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.

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.)

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	ec1fcc16af	Show original and resulting blob object info in diff output. This adds more cruft to diff --git header to record the blob SHA1 and the mode the patch/diff is intended to be applied against, to help the receiving end fall back on a three-way merge. The new header looks like this: diff --git a/apply.c b/apply.c index 7be5041..8366082 100644 --- a/apply.c +++ b/apply.c @@ -14,6 +14,7 @@ // files that are being modified, but doesn't apply the patch // --stat does just a diffstat, and doesn't actually apply +// --show-index-info shows the old and new index info for... ... Upon receiving such a patch, if the patch did not apply cleanly to the target tree, the recipient can try to find the matching old objects in her object database and create a temporary tree, apply the patch to that temporary tree, and attempt a 3-way merge between the patched temporary tree and the target tree using the original temporary tree as the common ancestor. The patch lifts the code to compute the hash for an on-filesystem object from update-index.c and makes it available to the diff output routine.

Junio C Hamano	215a7ad1ef	Big tool rename. As promised, this is the "big tool rename" patch. The primary differences since 0.99.6 are: (1) git-*-script are no more. The commands installed do not have any such suffix so users do not have to remember if something is implemented as a shell script or not. (2) Many command names with 'cache' in them are renamed with 'index' if that is what they mean. There are backward compatibility symblic links so that you and Porcelains can keep using the old names, but the backward compatibility support is expected to be removed in the near future.

Junio C Hamano	2bbcddee87	Adjust diff-raw tests to the status letter change. We use 'A' for added files instead of 'N' to make the it visually easier to distinguish from 'M' now. While we are at it, make the test scripts executable. Yes, I know it does not matter because t/Makefile runs them explicitly with "sh tXXXX-blah.sh", but being consistent is always better.

Linus Torvalds	dc93841715	diff 'rename' format change. Clearly even Junio felt git "rename" header lines should say "from/to" instead of "old/new", since he wrote the documentation that way. This way it also matches "copy". git-apply will accept both versions, at least for a while.	20 years ago
Junio C Hamano	25d5ea410f	[PATCH] Redo rename/copy detection logic. Earlier implementation had a major screw-up in the memory management area. Rename/copy logic sometimes borrowed a pointer to a structure without any provision for downstream to determine which pointer is shared and which is not. This resulted in the later clean-up code to sometimes double free such structure, resulting in a segfault. This made -M and -C useless. Another problem the earlier implementation had was that it reordered the patches, and forced the logic to differentiate renames and copies to depend on that particular order. This problem was fixed by teaching rename/copy detection logic not to do any reordering, and rename-copy differentiator not to depend on the order of the patches. The diffs will leave rename/copy detector in the same destination path order as the patch that was fed into it. Some test vectors have been reordered to accommodate this change. It also adds a sanity check logic to the human-readable diff-raw output to detect paths with embedded TAB and LF characters, which cannot be expressed with that format. This idea came up during a discussion with Chris Wedgwood. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Junio C Hamano	60896c7bfe	[PATCH] Be careful with symlinks when detecting renames and copies. Earlier round was not treating symbolic links carefully enough, and would have produced diff output that renamed/copied then edited the contents of a symbolic link, which made no practical sense. Change it to detect only pure renames. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
