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	5cfcd07c93	Retire diff-helper. The textual diff generation with built-in '-p' in diff-* brothers has proven to be useful enough that git-diff-helper outlived its usefulness. Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
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.

Junio C Hamano	4727f64003	[PATCH] Make -C less eager. Like diff-tree, this patch makes -C option for diff-* brothers to use only pre-image of modified files as rename/copy detection by default. Give --find-copies-harder to use unmodified files to find copies from as well. This also fixes "diff-files -C" problem earlier noticed by Linus. It was feeding the null sha1 even when the file in the work tree was known to match what is in the index file. This resulted in diff-files showing everything in the project.

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	edb0c72428	[PATCH] diff: consolidate test helper script pieces. There were duplicate script pieces to help comparing diff output, which this patch consolidates into the t/diff-lib.sh library.

Junio C Hamano	ddafa7e933	[PATCH] diff-helper: Fix R/C score parsing under -z flag. The score number that follow R/C status were parsed but the parse pointer was not updated, causing the entire line to become unrecognized. This patch fixes this problem. There was a test missing to catch this breakage, which this commit adds as t4009-diff-rename-4.sh. The diff-raw tests used in related t4005-diff-rename-2.sh (the same test without -z) and t4007-rename-3.sh were stricter than necessarily, despite that the comment for the tests said otherwise. This patch also corrects them. The documentation is updated to say that the status can optionally be followed by a number called "score"; it does not have to stay similarity index forever and there is no reason to limit it only to C and R.

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	bceafe752c	[PATCH] Fix diff-pruning logic which was running prune too early. For later stages to reorder patches, pruning logic and rename detection logic should not decide which delete to discard (because another entry said it will take over the file as a rename) until the very end. Also fix some tests that were assuming the earlier "last one is rename or keep everything else is copy" semantics of diff-raw format, which no longer is true.

Junio C Hamano	b6d8f309d9	[PATCH] diff-raw format update take #2 . This changes the diff-raw format again, following the mailing list discussion. The new format explicitly expresses which one is a rename and which one is a copy. The documentation and tests are updated to match this change.

Junio C Hamano	f7c1512af8	[PATCH] Rename/copy detection fix. The rename/copy detection logic in earlier round was only good enough to show patch output and discussion on the mailing list about the diff-raw format updates revealed many problems with it. This patch fixes all the ones known to me, without making things I want to do later impossible, mostly related to patch reordering. (1) Earlier rename/copy detector determined which one is rename and which one is copy too early, which made it impossible to later introduce diffcore transformers to reorder patches. This patch fixes it by moving that logic to the very end of the processing. (2) Earlier output routine diff_flush() was pruning all the "no-change" entries indiscriminatingly. This was done due to my false assumption that one of the requirements in the diff-raw output was not to show such an entry (which resulted in my incorrect comment about "diff-helper never being able to be equivalent to built-in diff driver"). My special thanks go to Linus for correcting me about this. When we produce diff-raw output, for the downstream to be able to tell renames from copies, sometimes it _is_ necessary to output "no-change" entries, and this patch adds diffcore_prune() function for doing it. (3) Earlier diff_filepair structure was trying to be not too specific about rename/copy operations, but the purpose of the structure was to record one or two paths, which _was_ indeed about rename/copy. This patch discards xfrm_msg field which was trying to be generic for this wrong reason, and introduces a couple of fields (rename_score and rename_rank) that are explicitly specific to rename/copy logic. One thing to note is that the information in a single diff_filepair structure _still_ does not distinguish renames from copies, and it is deliberately so. This is to allow patches to be reordered in later stages. (4) This patch also adds some tests about diff-raw format output and makes sure that necessary "no-change" entries appear on the output.
