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	b58f23b38a	[PATCH] Fix diff output take #4 . This implements the output format suggested by Linus in <Pine.LNX.4.58.0505161556260.18337@ppc970.osdl.org>, except the imaginary diff option is spelled "diff --git" with double dashes as suggested by Matthias Urlichs.

Junio C Hamano	273b98343c	[PATCH 1/3] Update mode-change strings in diff output. This updates the mode change strings to be a bit more machine friendly. Although this might go against the spirit of readability for human consumption, these mode bits strings are shown only when unusual things (mode change, file creation and deletion) happens, output normalized for machine consumption would be permissible.

Junio C Hamano	d19938ab60	Rename environment variables. H. Peter Anvin mentioned that using SHA1_whatever as an environment variable name is not nice and we should instead use names starting with "GIT_" prefix to avoid conflicts. Here is what this patch does: * Renames the following environment variables: New name Old Name GIT_AUTHOR_DATE AUTHOR_DATE GIT_AUTHOR_EMAIL AUTHOR_EMAIL GIT_AUTHOR_NAME AUTHOR_NAME GIT_COMMITTER_EMAIL COMMIT_AUTHOR_EMAIL GIT_COMMITTER_NAME COMMIT_AUTHOR_NAME GIT_ALTERNATE_OBJECT_DIRECTORIES SHA1_FILE_DIRECTORIES GIT_OBJECT_DIRECTORY SHA1_FILE_DIRECTORY * Introduces a compatibility macro, gitenv(), which does an getenv() and if it fails calls gitenv_bc(), which in turn picks up the value from old name while giving a warning about using an old name. * Changes all users of the environment variable to fetch environment variable with the new name using gitenv(). * Updates the documentation and scripts shipped with Linus GIT distribution. The transition plan is as follows: * We will keep the backward compatibility list used by gitenv() for now, so the current scripts and user environments continue to work as before. The users will get warnings when they have old name but not new name in their environment to the stderr. * The Porcelain layers should start using new names. However, just in case it ends up calling old Plumbing layer implementation, they should also export old names, taking values from the corresponding new names, during the transition period. * After a transition period, we would drop the compatibility support and drop gitenv(). Revert the callers to directly call getenv() but keep using the new names. The last part is probably optional and the transition duration needs to be set to a reasonable value.

Thomas Glanzmann	a1df57abb9	[PATCH] Add #include <limits.h> so that git compiles under Solaris <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.

Junio C Hamano	b28858bf65	Update diff engine for symlinks stored in the cache. This patch updates the external diff interface engine for the change to store the symbolic links in the cache, recently done by Kay Sievers. The main thing it does is when comparing with the work tree, it prepares the counterpart to the blob being compared by doing a readlink followed by sending that result to a temporary file to be diffed.

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	6fa28064b0	Terminate diff-* on non-zero exit from GIT_EXTERNAL_DIFF (slightly updated from the version posted to the GIT mailing list with small bugfixes). This patch changes the git-apply-patch-script to exit non-zero when the patch cannot be applied. Previously, the external diff driver deliberately ignored the exit status of GIT_EXTERNAL_DIFF command, which was a design mistake. It now stops the processing when GIT_EXTERNAL_DIFF exits non-zero, so the damages from running git-diff-* with git-apply-patch-script between two wrong trees can be contained. The "diff" command line generated by the built-in driver is changed to always exit 0 in order to match this new behaviour. I know Pasky does not use GIT_EXTERNAL_DIFF yet, so this change should not break Cogito, either. Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Linus Torvalds	0980d9b3a5	Change the prefix for builtin diff generation. It's silly, and it shouldn't matter, but every time I look at the diffs, I ended up just worrying why "l/" and "k/" as the prefixes. Junio says it's a tribute to linux-kernel, but graciously also said I can change it to something else. So make it "a/" and "b/" until somebody else complains ;)	20 years ago
Junio C Hamano	c983370e5e	[PATCH] Rework built-in diff to make its output more dense. Linus says, The fewer lines there are that don't usually tell a human anything, the better. Dense is good. This patch makes the default diff output more dense. This removes the previous misguided attempt to be cg-patch compatible.

Junio C Hamano	532149d727	[PATCH] diff.c: clean temporary files When diff-cache -p and friends are interrupted, they can leave their temporary files behind. Also when the external diff program is killed instead of exiting (this usually happens when piping the output to a pager, which can cause SIGPIPE when the user quits viewing the diff early), they incorrectly died without cleaning their temporary file. This fixes these problems. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Junio C Hamano	2f97813870	[PATCH] Make diff-cache and friends output more cg-patch friendly. This changes the way the default arguments to diff are built when diff-cache and friends are invoked with -p and there is no GIT_EXTERNAL_DIFF environment variable. It attempts to be more cg-patch friendly by: - Showing diffs against /dev/null to denote added or removed files; - Showing file modes for existing files as a comment after the diff label. Unfortunately with this change GIT_DIFF_CMD customization cannot be supported easily anymore, so it has been dropped. GIT_DIFF_OPTS customization to change diffs from unified to context is still there, though.

Linus Torvalds	4765dd57e6	diff.c: don't add extra '/' to pathname The "base" string already contains any finishing "/", so the way to get the full pathname is to just concatenate the base and path directly, with no extra slashes in between.	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.
