2005-05-29[PATCH] Do not include unused header files.Junio C Hamano
Some source files were including "delta.h" without actually needing it. Remove them. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-29[PATCH] Make pathspec only care about the detination tree.Junio C Hamano
Earlier it had a misguided attempt to include paths that matches either source tree or destination tree after the rename/copy detection. The new semantics will be that pathspec defines a narrowed down world the diffcore operates in, so it should not even look at where in the source tree the path came from.

2005-05-29[PATCH] Introduce diff_free_filepair() funcion.Junio C Hamano
This introduces a new function to free a common data structure, and plugs some leaks. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-27[PATCH] allow pathspec to end with a slashJunio C Hamano
The recent rewrite broke "git-whatchanged -v -p drivers/usb/" but "git-whatchanged -v -p drivers/usb" still works. Just strip out the trailing slashes internally to make it work again. It uses compare-thing-with-number comparison order instead of visual comparison order ;-). Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-25[PATCH] Use pathspec array correctlyJunio C Hamano
Oh, I am an idiot. Repeating the same check against the first element of pathspec array as many times as the pathspec array has elements in it would not do us any good. This patch allows you to specify more than one pathspec to diff-tree family and have them actually used.

2005-05-23[PATCH] Rename/copy detection fix.Junio C Hamano
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.

2005-05-22[PATCH] Diffcore updates.Junio C Hamano
This moves the path selection logic from individual programs to a new diffcore transformer (diff-tree still needs to have its own for performance reasons). Also the header printing code in diff-tree was tweaked not to produce anything when pickaxe is in effect and there is nothing interesting to report. An interesting example is the following in the GIT archive itself: $ git-whatchanged -p -C -S'or something in a real script' Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
