Junio C Hamano	bceafe752c	[PATCH] Fix diff-pruning logic which was running prune too early. For later stages to reorder patches, pruning logic and rename detection logic should not decide which delete to discard (because another entry said it will take over the file as a rename) until the very end. Also fix some tests that were assuming the earlier "last one is rename or keep everything else is copy" semantics of diff-raw format, which no longer is true.

Junio C Hamano	b6d8f309d9	[PATCH] diff-raw format update take #2 . This changes the diff-raw format again, following the mailing list discussion. The new format explicitly expresses which one is a rename and which one is a copy. The documentation and tests are updated to match this change.

Junio C Hamano	6b14d7faf0	[PATCH] Diffcore updates. 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>	20 years ago
Junio C Hamano	81e50eabf0	[PATCH] The diff-raw format updates. Update the diff-raw format as Linus and I discussed, except that it does not use sequence of underscore '_' letters to express nonexistence. All '0' mode is used for that purpose instead. The new diff-raw format can express rename/copy, and the earlier restriction that -M and -C _must_ be used with the patch format output is no longer necessary. The patch makes -M and -C flags independent of -p flag, so you need to say git-whatchanged -M -p to get the diff/patch format. Updated are both documentations and tests.

Junio C Hamano	38c6f78059	[PATCH] Prepare diffcore interface for diff-tree header supression. This does not actually supress the extra headers when pickaxe is used, but prepares enough support for diff-tree to implement it.

Junio C Hamano	52e9578985	[PATCH] Introducing software archaeologist's tool "pickaxe". This steals the "pickaxe" feature from JIT and make it available to the bare Plumbing layer. From the command line, the user gives a string he is intersted in. Using the diff-core infrastructure previously introduced, it filters the differences to limit the output only to the diffs between <src> and <dst> where the string appears only in one but not in the other. For example: $ ./git-rev-list HEAD \| ./git-diff-tree -Sdiff-tree-helper --stdin -M would show the diffs that touch the string "diff-tree-helper". In real software-archaeologist application, you would typically look for a few to several lines of code and see where that code came from. The "pickaxe" module runs after "rename/copy detection" module, so it even crosses the file rename boundary, as the above example demonstrates.

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.

Junio C Hamano	915838c3cb	[PATCH] Diff-helper update This patch adds a framework and a stub implementation of rename detection to diff-helper program. The current stub code is just enough to detect pure renames in diff-tree output and not fancier. The plan is perhaps to use the same delta code when Nico's delta storage patch is merged for similarity evaluation purposes.

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.
