git/builtin/diff-tree.c, branch v2.22.2

Merge branch 'en/combined-all-paths'

2019-03-07T00:59:54Z

Output from "diff --cc" did not show the original paths when the merge involved renames. A new option adds the paths in the original trees to the output. * en/combined-all-paths: log,diff-tree: add --combined-all-paths option

log,diff-tree: add --combined-all-paths option

2019-02-08T04:15:25Z

The combined diff format for merges will only list one filename, even if rename or copy detection is active. For example, with raw format one might see: ::100644 100644 100644 fabadb8 cc95eb0 4866510 MM describe.c ::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM bar.sh ::100644 100644 100644 e07d6c5 9042e82 ee91881 RR phooey.c This doesn't let us know what the original name of bar.sh was in the first parent, and doesn't let us know what either of the original names of phooey.c were in either of the parents. In contrast, for non-merge commits, raw format does provide original filenames (and a rename score to boot). In order to also provide original filenames for merge commits, add a --combined-all-paths option (which must be used with either -c or --cc, and is likely only useful with rename or copy detection active) so that we can print tab-separated filenames when renames are involved. This transforms the above output to: ::100644 100644 100644 fabadb8 cc95eb0 4866510 MM desc.c desc.c desc.c ::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM foo.sh bar.sh bar.sh ::100644 100644 100644 e07d6c5 9042e82 ee91881 RR fooey.c fuey.c phooey.c Further, in patch format, this changes the from/to headers so that instead of just having one "from" header, we get one for each parent. For example, instead of having --- a/phooey.c +++ b/phooey.c we would see --- a/fooey.c --- a/fuey.c +++ b/phooey.c Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

cache.h: flip NO_THE_INDEX_COMPATIBILITY_MACROS switch

2019-01-24T19:55:06Z

By default, index compat macros are off from now on, because they could hide the_index dependency. Only those in builtin can use it. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

read-cache.c: kill read_index()

2019-01-14T20:13:04Z

read_index() shares the same problem as hold_locked_index(): it assumes $GIT_DIR/index. Move all call sites to repo_read_index() instead. read_index_preload() and read_index_unmerged() are also killed as a consequence. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

revision.c: remove implicit dependency on the_index

diff.c: move read_index() code back to the caller

2018-08-13T21:14:42Z

This code is only needed for diff-tree (since f0c6b2a2fd ([PATCH] Optimize diff-tree -[CM] --stdin - 2005-05-27)). Let the caller do the preparation instead and avoid read_index() in diff.c code. read_index() should be avoided (in addition to the_index) because it uses get_index_file() underneath to get the path $GIT_DIR/index. This effectively pulls the_repository in and may become the only reason to pull a 'struct repository *' in diff.c. Let's keep the dependencies as few as possible and kick it back to diff-tree.c Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

commit: add repository argument to lookup_commit

2018-06-29T17:43:39Z

Add a repository argument to allow callers of lookup_commit to be more specific about which repository to handle. This is a small mechanical change; it doesn't change the implementation to handle repositories other than the_repository yet. As with the previous commits, use a macro to catch callers passing a repository other than the_repository at compile time. Signed-off-by: Stefan Beller Signed-off-by: Junio C Hamano
