Junio C Hamano	427dcb4bca	[PATCH] Diff overhaul, adding half of copy detection. This introduces the diff-core, the layer between the diff-tree family and the external diff interface engine. The calls to the interface diff-tree family uses (diff_change and diff_addremove) have not changed and will not change. The purpose of the diff-core layer is to provide an infrastructure to transform the set of differences sent from the applications, before sending them to the external diff interface. The recently introduced rename detection code has been rewritten to use the diff-core facility. When applications send in separate creates and deletes, matching ones are transformed into a single rename-and-edit diff, and sent out to the external diff interface as such. This patch also enhances the rename detection code further to be able to detect copies. Currently this happens only as long as copy sources appear as part of the modified files, but there already is enough provision for callers to report unmodified files to diff-core, so that they can be also used as copy source candidates. Extending the callers this way will be done in a separate patch. Please see and marvel at how well this works by trying out the newly added t/t4003-diff-rename-1.sh test script.

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	e4f5b8c69d	Fix thinko in the logic to refuse unmerged path fed to git-apply-patch-script. An unmerged path is given as the sole parameter to the script, so it should check against $# being 1, not 2. Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Junio C Hamano	fc54a9c30c	Update git-apply-patch-script for symbolic links. This patch updates the git-apply-patch-script for the symbolic links in the cache, recently added by Kay Sievers. It currently is very anal about symbolic link changes. It refuses to change between a regular file and a symbolic link, and only allows symbolic link changes if the patch is based on the same original.

Junio C Hamano	8a9d32b7e9	When the patch tries to create a new file and the file exists, abort. This fixes an error introduced to git-apply-patch-script in the previous round. We do not invoke patch for create/delete case, so we need to be a bit careful about detecting conflicts like this. 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
Junio C Hamano	285bf834be	Make git-apply-patch-script executable.	20 years ago
Junio C Hamano	7fa76eeb75	[PATCH] typo fixes to git-apply-patch-script When git-apply-patch-script creates a new file without executable mode set, a typo caused it not to report that activity to the user. Also it was mistakenly running git-update-cache twice for newly created or deleted paths. This patch fixes these problems.

Junio C Hamano	5d2f8b2753	[PATCH] Add git-apply-patch-script. I said: - Stop attempting to be compatible with cg-patch, and drop (mode:XXXXXX) bits from the diff. - Do keep the /dev/null change for created and deleted case. - No "Index:" line, no "Mode change:" line, anywhere in the output. Anything that wants the mode bits and sha1 hash can do things from GIT_EXTERNAL_DIFF mechanism. Maybe document suggested usage better. This adds an example script git-apply-patch-script, that can be used as the GIT_EXTERNAL_DIFF to apply changes between two trees directly on the current work tree, like this: GIT_EXTERNAL_DIFF=git-apply-patch-script git-diff-tree -p <tree> <tree> Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
