Junio C Hamano	99665af5c0	[PATCH 2/3] Rename git-diff-tree-helper to git-diff-helper. It used to be that diff-tree needed helper support to parse its raw output to generate diffs, but these days git-diff-* family produces the same output and the helper is not tied to diff-tree anymore. Drop "tree" from its name. This commit is done separately to record just the rename and no file content changes. The changes in the renamed files are recorded in the next commit.

Junio C Hamano	b46f0b6dfd	Optimize diff-cache -p --cached This patch optimizes "diff-cache -p --cached" by avoiding to inflate blobs into temporary files when the blob recorded in the cache matches the corresponding file in the work tree. The file in the work tree is passed as the comparison source in such a case instead. This optimization kicks in only when we have already read the cache this optimization and this is deliberate. Especially, diff-tree does not use this code, because changes are contained in small number of files relative to the project size most of the time, and reading cache is so expensive for a large project that the cost of reading it outweighs the savings by not inflating blobs. Also this patch cleans up the structure passed from diff clients by removing one unused structure member. Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Junio C Hamano	77eb272046	[PATCH] Reworked external diff interface. This introduces three public functions for diff-cache and friends can use to call out to the GIT_EXTERNAL_DIFF program when they wish to. A normal "add/remove/change" entry is turned into 7-parameter process invocation of GIT_EXTERNAL_DIFF program as before. In addition, the program can now be called with a single parameter when diff-cache and friends want to report an unmerged path.

Junio C Hamano	be3cfa85f4	[PATCH] Diff-tree-helper take two. This reworks the diff-tree-helper and show-diff to further make external diff command interface simpler. These commands now honor GIT_EXTERNAL_DIFF environment variable which can point at an arbitrary program that takes 7 parameters: name file1 file1-sha1 file1-mode file2 file2-sha1 file2-mode The parameters for an external diff command are as follows: name this invocation of the command is to emit diff for the named cache/tree entry. file1 pathname that holds the contents of the first file. This can be a file inside the working tree, or a temporary file created from the blob object, or /dev/null. The command should not attempt to unlink it -- the temporary is unlinked by the caller. file1-sha1 sha1 hash if file1 is a blob object, or "." otherwise. file1-mode mode bits for file1, or "." for a deleted file. If GIT_EXTERNAL_DIFF environment variable is not set, the default is to invoke diff with the set of parameters old show-diff used to use. This built-in implementation honors the GIT_DIFF_CMD and GIT_DIFF_OPTS environment variables as before.

Junio C Hamano	86436c2828	[PATCH] Split external diff command interface to a separate file. With this patch, the non-core'ish part of show-diff command that invokes an external "diff" comand to obtain patches is split into a separate file. The next patch will introduce a new command, diff-tree-helper, which uses this common diff interface to format diff-tree and diff-cache output into a patch form.
