* diff: --full-indexJunio C Hamano2005-11-16
| | | | | | | | | A new option, --full-index, is introduced to diff family. This causes the full object name of pre- and post-images to appear on the index line of patch formatted output, to be used in conjunction with --allow-binary-replacement option of git-apply.

* diff: make default rename detection limit configurable.Junio C Hamano2005-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A while ago, a rename-detection limit logic was implemented as a response to this thread: http://marc.theaimsgroup.com/?l=git&m=112413080630175 where gitweb was found to be using a lot of time and memory to detect renames on huge commits. git-diff family takes -l<num> flag, and if the number of paths that are rename destination candidates (i.e. new paths with -M, or modified paths with -C) are larger than that number, skips rename/copy detection even when -M or -C is specified on the command line. This commit makes the rename detection limit easier to use. You can have: [diff] renamelimit = 30 in your .git/config file to specify the default rename detection limit. You can override this from the command line; giving 0 means 'unlimited': git diff -M -l0 We might want to change the default behaviour, when you do not have the configuration, to limit it to say 20 paths or so. This would also help the diffstat generation after a big 'git pull'. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Split up tree diff functions into tree-diff.c libraryLinus Torvalds2005-10-22
| | | | | | | | | | | | | | | | | | | | | | This makes the tree diff functionality independent of the "git-diff-tree" program, by splitting the core functionality up into a library file. This will be needed for when we teach git-rev-list to only follow a specified set of pathnames, rather than the global revision history. Most of it is a fairly straightforward code move, but it also involves some calling convention cleanup, and moving some of the static variables from diff-tree.c into the options structure. The actual tree change callback routines also become paramterized by the diff_options structure, allowing the library functionality to do something else than just show the diff on stdout. Right now the only user of this functionality remains git-diff-tree itself. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

* Show original and resulting blob object info in diff output.Junio C Hamano2005-10-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds more cruft to diff --git header to record the blob SHA1 and the mode the patch/diff is intended to be applied against, to help the receiving end fall back on a three-way merge. The new header looks like this: diff --git a/apply.c b/apply.c index 7be5041..8366082 100644 --- a/apply.c +++ b/apply.c @@ -14,6 +14,7 @@ // files that are being modified, but doesn't apply the patch // --stat does just a diffstat, and doesn't actually apply +// --show-index-info shows the old and new index info for... ... Upon receiving such a patch, if the patch did not apply cleanly to the target tree, the recipient can try to find the matching old objects in her object database and create a temporary tree, apply the patch to that temporary tree, and attempt a 3-way merge between the patched temporary tree and the target tree using the original temporary tree as the common ancestor. The patch lifts the code to compute the hash for an on-filesystem object from update-index.c and makes it available to the diff output routine. Signed-off-by: Junio C Hamano <junkio@cox.net>

* Fix copy marking from diffcore-rename.Junio C Hamano2005-09-10
| | | | | | | | | | | When (A,B) ==> (B,C) rename-copy was detected, we incorrectly said that C was created by copying B. This is because we only check if the path of rename/copy source still exists in the resulting tree to see if the file is renamed out of existence. In this case, the new B is created by copying or renaming A, so the original B is lost and we should say C is a rename of B not a copy of B. Signed-off-by: Junio C Hamano <junkio@cox.net>

| | | | | | | | | | | | | | | When I run git-diff-tree on big change, it seems the command eats so much memory. so I just put git under valgrind to see what's going on. diff_free_filespec_data() doesn't free diff_filespec itself.

* [PATCH] Add --diff-filter= output restriction to diff-* family.Junio C Hamano2005-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | This is a halfway between debugging aid and a helper to write an ultra-smart merge scripts. The new option takes a string that consists of a list of "status" letters, and limits the diff output to only those classes of changes, with two exceptions: - A broken pair (aka "complete rewrite"), does not match D (deleted) or N (created). Use B to look for them. - The letter "A" in the diff-filter string does not match anything itself, but causes the entire diff that contains selected patches to be output (this behaviour is similar to that of --pickaxe-all for the -S option). For example, $ git-rev-list HEAD | git-diff-tree --stdin -s -v -B -C --diff-filter=BCR shows a list of commits that have complete rewrite, copy, or rename.

* [PATCH] diff: Update -B heuristics.Junio C Hamano2005-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Linus pointed out on the mailing list discussion, -B should break a files that has many inserts even if it still keeps enough of the original contents, so that the broken pieces can later be matched with other files by -M or -C. However, if such a broken pair does not get picked up by -M or -C, we would want to apply different criteria; namely, regardless of the amount of new material in the result, the determination of "rewrite" should be done by looking at the amount of original material still left in the result. If you still have the original 97 lines from a 100-line document, it does not matter if you add your own 13 lines to make a 110-line document, or if you add 903 lines to make a 1000-line document. It is not a rewrite but an in-place edit. On the other hand, if you did lose 97 lines from the original, it does not matter if you added 27 lines to make a 30-line document or if you added 997 lines to make a 1000-line document. You did a complete rewrite in either case. This patch introduces a post-processing phase that runs after diffcore-rename matches up broken pairs diffcore-break creates. The purpose of this post-processing is to pick up these broken pieces and merge them back into in-place modifications. For this, the score parameter -B option takes is changed into a pair of numbers, and it takes "-B99/80" format when fully spelled out. The first number is the minimum amount of "edit" (same definition as what diffcore-rename uses, which is "sum of deletion and insertion") that a modification needs to have to be broken, and the second number is the minimum amount of "delete" a surviving broken pair must have to avoid being merged back together. It can be abbreviated to "-B" to use default for both, "-B9" or "-B9/" to use 90% for "edit" but default (80%) for merge avoidance, or "-B/75" to use default (99%) "edit" and 75% for merge avoidance.

* [PATCH] diff: mode bits fixesJunio C Hamano2005-06-01
| | | | | | | | | | | | | | | | | | | The core GIT repository has trees that record regular file mode in 0664 instead of normalized 0644 pattern. Comparing such a tree with another tree that records the same file in 0644 pattern without content changes with git-diff-tree causes it to feed otherwise unmodified pairs to the diff_change() routine, which triggers a sanity check routine and barfs. This patch fixes the problem, along with the fix to another caller that uses unnormalized mode bits to call diff_change() routine in a similar way. Without this patch, you will see "fatal error" from diff-tree when you run git-deltafy-script on the core GIT repository itself.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new diffcore transformation, diffcore-break.c, is introduced. When the -B flag is given, a patch that represents a complete rewrite is broken into a deletion followed by a creation. This makes it easier to review such a complete rewrite patch. The -B flag takes the same syntax as the -M and -C flags to specify the minimum amount of non-source material the resulting file needs to have to be considered a complete rewrite, and defaults to 99% if not specified. As the new test t4008-diff-break-rewrite.sh demonstrates, if a file is a complete rewrite, it is broken into a delete/create pair, which can further be subjected to the usual rename detection if -M or -C is used. For example, if file0 gets completely rewritten to make it as if it were rather based on file1 which itself disappeared, the following happens: The original change looks like this: file0 --> file0' (quite different from file0) file1 --> /dev/null After diffcore-break runs, it would become this: file0 --> /dev/null /dev/null --> file0' file1 --> /dev/null Then diffcore-rename matches them up: file1 --> file0' The internal score values are finer grained now. Earlier maximum of 10000 has been raised to 60000; there is no user visible changes but there is no reason to waste available bits.

This is _not_ a bugfix --- the existing code stat() on the file ifself and does the same computation on st.st_mode to compute the mode the same way the caller did to give the original mode.

* [PATCH] Optimize diff-tree -[CM] --stdinJunio C Hamano2005-05-29
| | | | | | | | | | | | | | | | | | | | | | | | This attempts to optimize "diff-tree -[CM] --stdin", which compares successible tree pairs. This optimization does not make much sense for other commands in the diff-* brothers. When reading from --stdin and using rename/copy detection, the patch makes diff-tree to read the current index file first. This is done to reuse the optimization used by diff-cache in the non-cached case. Similarity estimator can avoid expanding a blob if the index says what is in the work tree has an exact copy of that blob already expanded. Another optimization the patch makes is to check only file sizes first to terminate similarity estimation early. In order for this to work, it needs a way to tell the size of the blob without expanding it. Since an obvious way of doing it, which is to keep all the blobs previously used in the memory, is too costly, it does so by keeping the filesize for each object it has already seen in memory.
