2005-05-15[PATCH 2/3] Rename git-diff-tree-helper to git-diff-helper.Junio C Hamano
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.

2005-05-07[PATCH] Add #include <limits.h> so that git compiles under SolarisThomas Glanzmann
<JC> Editorial Note. We may want to include standard headers in one of those headers everybody includes, e.g. cache.h, to reduce clutters, but this commit is as Thomas posted to the GIT list. Date: Sat, 7 May 2005 10:41:41 +0200 Signed-off-by: Thomas Glanzmann <> Signed-off-by: Junio C Hamano <>
2005-05-04Optimize diff-cache -p --cachedJunio C Hamano
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 <>
2005-05-01[PATCH] Resurrect diff-tree-helper -RJunio C Hamano
Diff-tree-helper take two patch inadvertently dropped the support of -R option, which is necessary to produce reverse diff based on diff-cache and diff-files output (diff-tree does not matter since you can feed two trees in reverse order). This patch restores it. Signed-off-by: Junio C Hamano <> Signed-off-by: Linus Torvalds <>
2005-04-28[PATCH] diff-tree-helper: do not report unmerged path outside specification.Junio C Hamano
My bad. diff-tree-helper reports all unmerged paths even when the command line specifies to filter the paths. This patch fixes it. Also reverse-diff option was left out during the last round, which this patch restores as well. Signed-off-by: Junio C Hamano <> Signed-off-by: Linus Torvalds <>
2005-04-27[PATCH] Teach diff-tree-helper to handle unmerged paths.Junio C Hamano
This teaches diff-tree-helper to call diff_unmerge() so that it can report unmerged paths to GIT_EXTERNAL_DIFF, instead of consuming it on its own. Signed-off-by: Junio C Hamano <> Signed-off-by: Linus Torvalds <>
2005-04-27[PATCH] diff-cache/tree compatible output for show-diff (take 2).Junio C Hamano
This makes diff-tree-helper handle ("warn about") unmerged path entries U <path> <record-terminator> This is emitted once per unmerged path, no matter how many unmerged stages there are. Signed-off-by: Junio C Hamano <> Signed-off-by: Linus Torvalds <>
2005-04-26[PATCH] Diff-tree-helper take two.Junio C Hamano
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. Signed-off-by: Junio C Hamano <> Signed-off-by: Linus Torvalds <>
2005-04-26[PATCH] Introduce diff-tree-helper.Junio C Hamano
This patch introduces a new program, diff-tree-helper. It reads output from diff-cache and diff-tree, and produces a patch file. The diff format customization can be done the same way the show-diff uses; the same external diff interface introduced by the previous patch to drive diff from show-diff is used so this is not surprising. It is used like the following examples: $ diff-cache --cached -z <tree> | diff-tree-helper -z -R paths... $ diff-tree -r -z <tree1> <tree2> | diff-tree-helper -z paths... - As usual, the use of the -z flag is recommended in the script to pass NUL-terminated filenames through the pipe between commands. - The -R flag is used to generate reverse diff. It does not matter for diff-tree case, but it is sometimes useful to get a patch in the desired direction out of diff-cache. - The paths parameters are used to restrict the paths that appears in the output. Again this is useful to use with diff-cache, which, unlike diff-tree, does not take such paths restriction parameters. Signed-off-by: Junio C Hamano <> Signed-off-by: Linus Torvalds <>
