Junio C Hamano	bf1c32bdec	combine-diff: update --cc "uninteresting hunks" logic. Earlier logic was discarding hunks that has difference from only one parent or the same difference from all but one parent. This changes it to check if the differences on all lines are from the same sets of parents. This discards more uninteresting hunks and seems to match expectations more naturally.

Junio C Hamano	3c39e9bdeb	combine-diff: reuse diff from the same blob. When dealing with an insanely large Octopus, it is possible to optimize by noticing that more than one parents have the same blob and avoid running diff between a parent and the merge result by reusing an earlier result.

Junio C Hamano	ea726d02e9	diff-files: -c and --cc options. This ports the "combined diff" to diff-files so that differences to the working tree files since stage 2 and stage 3 are shown the same way as combined diff output from diff-tree for the merge commit would be shown if the current working tree files are committed.

Junio C Hamano	3ec1909fda	combine-diff: better hunk splitting. It considered an otherwise unchanged line that had line removals in front of it an interesting line, which caused hunks to have one extra the trailing context line. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	8828cdcb44	diff-tree --cc: squelch header generation on empty patch. Earlier round showed the commit log header and "diff --combined" header even for paths that had no interesting hunk under --cc flag. Move the header display logic around to squelch them. With this, a merge that does not have any interesting merges will not be shown with --cc option, unless -m is used at the same time. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	263eee29e9	combine-diff: extend --cc logic to Octopus. Santi Bejar points out that a hunk that changes from all the same common parents except one is uninteresting. The earlier round marked changes from only one parent uninteresting, but this also marks hunks that have the same change from all but one parent uninteresting, which is a natural extension of the original idea to Octopus merges.

Junio C Hamano	e228340961	combine-diff: minor output changes. Remove extra whitespace between the change indicators and the body text. That is more in line with the uncombined unified diff output (pointed out by Santi Bejar). When showing --cc, say so instead of saying just --combined.

Junio C Hamano	5290a0f812	combine-diff: fix appending at the tail of a list. ... and use the established pattern of tail initialized to point at the head pointer for an empty list, and updated to point at the next pointer field of the item at the tail when appending.

Junio C Hamano	d8f4790e6f	diff-tree --cc: denser combined diff output for a merge commit. Building on the previous '-c' (combined) option, '--cc' option squelches the output further by omitting hunks that consist of difference with solely one parent.

Junio C Hamano	af3feefa1d	diff-tree -c: show a merge commit a bit more sensibly. A new option '-c' to diff-tree changes the way a merge commit is displayed when generating a patch output. It shows a "combined diff" (hence the option letter 'c'), which looks like this: $ git-diff-tree --pretty -c -p `fec9ebf1` \| head -n 18 diff-tree fec9ebf... (from parents) Merge: 0620db3... 8a263ae... Author: Junio C Hamano <junkio@cox.net> Date: Sun Jan 15 22:25:35 2006 -0800 Merge fixes up to GIT 1.1.3 diff --combined describe.c @@@ +98,7 @@@ return (a_date > b_date) ? -1 : (a_date == b_date) ? 0 : 1; } - static void describe(char arg) - static void describe(struct commit cmit, int last_one) ++ static void describe(char arg, int last_one) { + unsigned char sha1[20]; + struct commit cmit; There are a few things to note about this feature: - The '-c' option implies '-p'. It also implies '-m' halfway in the sense that "interesting" merges are shown, but not all merges. - When a blob matches one of the parents, we do not show a diff for that path at all. For a merge commit, this option shows paths with real file-level merge (aka "interesting things"). - As a concequence of the above, an "uninteresting" merge is not shown at all. You can use '-m' in addition to '-c' to show the commit log for such a merge, but there will be no combined diff output. - Unlike "gitk", the output is monochrome. A '-' character in the nth column means the line is from the nth parent and does not appear in the merge result (i.e. removed from that parent's version). A '+' character in the nth column means the line appears in the merge result, and the nth parent does not have that line (i.e. added by the merge itself or inherited from another parent). The above example output shows that the function signature was changed from either parents (hence two "-" lines and a "++" line), and "unsigned char sha1[20]", prefixed by a " +", was inherited from the first parent. The code as sent to the list was buggy in few corner cases, which I have fixed since then. It does not bother to keep track of and show the line numbers from parent commits, which it probably should.
