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	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.

Linus Torvalds	e99d59ff0b	sparse cleanup Fix various things that sparse complains about: - use NULL instead of 0 - make sure we declare everything properly, or mark it static - use proper function declarations ("fn(void)" instead of "fn()") Sparse is always right.	20 years ago
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	660265909f	diff-cache shows differences for unmerged paths without --cache. While manually resolving a merge conflict, being able to run diff-cache without --cache option between files in the work tree and either of the ancestor trees is helpful to verify the hand merged result. However, diff-cache refuses to handle unmerged paths, even when run without --cache option. This changes the behaviour so that the above use case will report the differences between the compared tree and the magic 0{40} SHA1 (i.e. "look at the work tree"). When there is no corresponding file in the work tree, or when the command is run with "--cache" option, it continues to report "unmerged". Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Linus Torvalds	160c8433d9	git-diff-cache: add "-m" flag to match all non-checked-out files with the index. This allows you to work with a directory tree that isn't fully populated, without making diff-cache say that all the files are gone.	20 years ago
Kay Sievers	8ae0a8c514	[PATCH] git and symlinks as tracked content Allow to store and track symlink in the repository. A symlink is stored the same way as a regular file, only with the appropriate mode bits set. The symlink target is therefore stored in a blob object. This will hopefully make our udev repository fully functional. :) Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Linus Torvalds	3c249c9506	Add "get_sha1()" helper function. This allows the programs to use various simplified versions of the SHA1 names, eg just say "HEAD" for the SHA1 pointed to by the .git/HEAD file etc. For example, this commit has been done with git-commit-tree $(git-write-tree) -p HEAD instead of the traditional "$(cat .git/HEAD)" syntax.	20 years ago
Junio C Hamano	40469ee9c6	[PATCH] Rename and extend read_tree_with_tree_or_commit_sha1 This patch renames read_tree_with_tree_or_commit_sha1() to read_object_with_reference() and extends it to automatically dereference not just "commit" objects but "tag" objects.

Linus Torvalds	c9cddabe99	diff-cache: handle modified new files correctly Junio pointed out that diff-cache didn't handle the case of a new file that was different from its index entry correctly. It needs to check the working copy the same way the modified file case did.	20 years ago

Linus Torvalds	b0fe89caeb	diff-cache: fix handling of unmerged files. We've always warned about them properly, but we would then do the wrong thing if that filename existed in the tree we were comparing against (we'd think the file has been deleted, because we forgot about the unmerged cases).	20 years ago

Junio C Hamano	5697ecc7be	[PATCH] diff-cache buglet diff-cache attempts to first remove all merge entries before letting the diff_cache() do its work, but it incorrectly stops after the first merge-entry it finds.

Linus Torvalds	b5af910727	New "diff-cache" implementation. This one is about a million times simpler, and much more likely to be correct too. Instead of trying to match up a tree object against the index, we just read in the tree object side-by-side into the index, and just walk the resulting index file. This was what all the read-tree cleanups were all getting to.	20 years ago
Junio C Hamano	c5bac17ad2	[PATCH] Usage-string fixes. Usage string fixes to make maintenance easier (only one instance of a string to update not multiple copies). I've spotted and corrected inconsistent usage text in diff-tree while doing this. Also diff-cache and read-tree usage text have been corrected to match their up-to-date features. Earlier, neither "--cached" form of diff-cache nor "-m single-merge" form of read-tree were described.

Linus Torvalds	e74f8f6aa7	Add "diff-cache" helper program to compare a tree (or commit) with the current cache state and/or working directory. Very useful to see what has changed since the last commit, either in the index file or in the whole working directory. Also very possibly very buggy. Matching the two up is not entirely trivial.	20 years ago
