Junio C Hamano	427dcb4bca	[PATCH] Diff overhaul, adding half of copy detection. This introduces the diff-core, the layer between the diff-tree family and the external diff interface engine. The calls to the interface diff-tree family uses (diff_change and diff_addremove) have not changed and will not change. The purpose of the diff-core layer is to provide an infrastructure to transform the set of differences sent from the applications, before sending them to the external diff interface. The recently introduced rename detection code has been rewritten to use the diff-core facility. When applications send in separate creates and deletes, matching ones are transformed into a single rename-and-edit diff, and sent out to the external diff interface as such. This patch also enhances the rename detection code further to be able to detect copies. Currently this happens only as long as copy sources appear as part of the modified files, but there already is enough provision for callers to report unmodified files to diff-core, so that they can be also used as copy source candidates. Extending the callers this way will be done in a separate patch. Please see and marvel at how well this works by trying out the newly added t/t4003-diff-rename-1.sh test script.

Linus Torvalds	de809dbbce	Fix up previous commit Add '-R' flag to diff-tree, and change the test subdirectory shell files to be executable (something that Junio couldn't get me to do through the pure patch with my current patch handling infrastructure).	20 years ago
Junio C Hamano	57fe64a40d	[PATCH] diff overhaul This cleans up the way calls are made into the diff core from diff-tree family and diff-helper. Earlier, these programs had "if (generating_patch)" sprinkled all over the place, but those ugliness are gone and handled uniformly from the diff core, even when not generating patch format. This also allowed diff-cache and diff-files to acquire -R (reverse) option to generate diff in reverse. Users of diff-tree can swap two trees easily so I did not add -R there. [ Linus' note: I'll add -R to "diff-tree" too, since a "commit diff" doesn't have another tree to switch around: the other tree is always the parent(s) of the commit ] Also -M<digits-as-mantissa> suggestion made by Linus has been implemented. Documentation updates are also included. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Junio C Hamano	5c97558c9a	[PATCH] Detect renames in diff family. This rips out the rename detection engine from diff-helper and moves it to the diff core, and updates the internal calling convention used by diff-tree family into the diff core. In order to give the same option name to diff-tree family as well as to diff-helper, I've changed the earlier diff-helper '-r' option to '-M' (stands for Move; sorry but the natural abbreviation 'r' for 'rename' is already taken for 'recursive'). Although I did a fair amount of test with the git-diff-tree with existing rename commits in the core GIT repository, this should still be considered beta (preview) release. This patch depends on the diff-delta infrastructure just committed. This implements almost everything I wanted to see in this series of patch, except a few minor cleanups in the calling convention into diff core, but that will be a separate cleanup patch.
