71a3d27e	2013-02-08T10:06:47	Replace diff delta binary with flags Previously the git_diff_delta recorded if the delta was binary. This replaces that (with no net change in structure size) with a full set of flags. The flag values that were already in use for individual git_diff_file objects are reused for the delta flags, too (along with renaming those flags to make it clear that they are used more generally). This (a) makes things somewhat more consistent (because I was using a -1 value in the "boolean" binary field to indicate unset, whereas now I can just use the flags that are easier to understand), and (b) will make it easier for me to add some additional flags to the delta object in the future, such as marking the results of a copy/rename detection or other deltas that might want a special indicator. While making this change, I officially moved some of the flags that were internal only into the private diff header. This also allowed me to remove a gross hack in rename/copy detect code where I was overwriting the status field with an internal value.

9950d27a	2012-12-06T13:26:58	Clean up iterator APIs This removes the need to explicitly pass the repo into iterators where the repo is implied by the other parameters. This moves the repo to be owned by the parent struct. Also, this has some iterator related updates to the internal diff API to lay the groundwork for checkout improvements.
c7231c45	2012-11-30T16:31:42	Deploy GITERR_CHECK_VERSION
2f8d30be	2012-11-29T15:05:04	Deploy GIT_DIFF_OPTIONS_INIT
bbe6dbec	2012-11-14T23:29:48	Add explicit git_index ptr to diff and checkout A number of diff APIs and the `git_checkout_index` API take a `git_repository` object an operate on the index. This updates them to take a `git_index` pointer explicitly and only fall back on the `git_repository` index if the index input is NULL. This makes it easier to operate on a temporary index.
bad68c0a	2012-11-13T14:02:59	Add iterator for git_index object The index iterator could previously only be created from a repo object, but this allows creating an iterator from a `git_index` object instead (while keeping, though renaming, the old function).
0f3def71	2012-11-09T11:19:46	Fix various cross-platform build issues This fixes a number of warnings and problems with cross-platform builds. Among other things, it's not safe to name a member of a structure "strcmp" because that may be #defined.
55cbd05b	2012-11-08T16:56:34	Some diff refactorings to help code reuse There are some diff functions that are useful in a rewritten checkout and this lays some groundwork for that. This contains three main things: 1. Share the function diff uses to calculate the OID for a file in the working directory (now named `git_diff__oid_for_file` 2. Add a `git_diff__paired_foreach` function to iterator over two diff lists concurrently. Convert status to use it. 3. Move all the string/prefix/index entry comparisons into function pointers inside the `git_diff_list` object so they can be switched between case sensitive and insensitive versions. This makes them easier to reuse in various functions without replicating logic. As part of this, move a couple of index functions out of diff.c and into index.c.
db106d01	2012-10-30T09:40:50	Move rename detection into new file This improves the naming for the rename related functionality moving it to be called `git_diff_find_similar()` and renaming all the associated constants, etc. to make more sense. I also moved the new code (plus the existing `git_diff_merge`) into a new file `diff_tform.c` where I can put new functions related to manipulating git diff lists. This also updates the implementation significantly from the last revision fixing some ordering issues (where break-rewrite needs to be handled prior to copy and rename detection) and improving config option handling.
b4f5bb07	2012-10-23T16:40:51	Initial implementation of diff rename detection This implements the basis for diff rename and copy detection, although it is based on simple SHA comparison right now instead of using a matching algortihm. Just as `git_diff_merge` can be used as a post-pass on diffs to emulate certain command line behaviors, there is a new API `git_diff_detect` which will update a diff list in-place, adjusting some deltas to RENAMED or COPIED state (and also, eventually, splitting MODIFIED deltas where the change is too large into DELETED/ADDED pairs). This also adds a new test repo that will hold rename/copy/split scenarios. Right now, it just has exact-match rename and copy, but the tests are written to use tree diffs, so we should be able to add new test scenarios easily without breaking tests.
52a61bb8	2012-10-17T14:10:23	Fix minor bugs Fixed no-submodule speedup of new checkout code. Fixed missing final update to progress (which may go away, I realize). Fixed unused structure in header and incorrect comment.
bae957b9	2012-09-25T16:31:46	Add const to all shared pointers in diff API There are a lot of places where the diff API gives the user access to internal data structures and many of these were being exposed through non-const pointers. This replaces them all with const pointers for any object that the user can access but is still owned internally to the git_diff_list or git_diff_patch objects. This will probably break some bindings... Sorry!
64286308	2012-09-25T10:48:50	Fix bugs in new diff patch code This fixes all the bugs in the new diff patch code. The only really interesting one is that when we merge two diffs, we now have to actually exclude diff delta records that are not supposed to be tracked, as opposed to before where they could be included because they would be skipped silently by `git_diff_foreach()`. Other than that, there are just minor errors.
5f69a31f	2012-09-24T20:52:34	Initial implementation of new diff patch API Replacing the `git_iterator` object, this creates a simple API for accessing the "patch" for any file pair in a diff list and then gives indexed access to the hunks in the patch and the lines in the hunk. This is the initial implementation of this revised API - it is still broken, but at least builds cleanly.
b36effa2	2012-09-10T09:59:14	Replace git_diff_iterator_num_files with progress The `git_diff_iterator_num_files` API was problematic, since we don't actually know the exact number of files to be iterated over until we load those files into memory. This replaces it with a new `git_diff_iterator_progress` API that goes from 0 to 1, and moves and renamed the old API for the internal places that can tolerate a max value instead of an exact value.
60b9d3fc	2012-09-05T15:00:40	Implement filters for status/diff blobs This adds support to diff and status for running filters (a la crlf) on blobs in the workdir before computing SHAs and before generating text diffs. This ended up being a bit more code change than I had thought since I had to reorganize some of the diff logic to minimize peak memory use when filtering blobs in a diff. This also adds a cap on the maximum size of data that will be loaded to diff. I set it at 512Mb which should match core git. Right now it is a #define in src/diff.h but it could be moved into the public API if desired.
f335ecd6	2012-08-30T14:24:16	Diff iterators This refactors the diff output code so that an iterator object can be used to traverse and generate the diffs, instead of just the `foreach()` style with callbacks. The code has been rearranged so that the two styles can still share most functions. This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses that as a common error code for marking the end of iteration when using a iterator style of object.
0abd7244	2012-06-04T16:17:41	Fix filemode comparison in diffs File modes were both not being ignored properly on platforms where they should be ignored, nor be diffed consistently on platforms where they are supported. This change adds a number of diff and status filemode change tests. This also makes sure that filemode-only changes are included in the diff output when they occur and that filemode changes are ignored successfully when core.filemode is false. There is no code that automatically toggles core.filemode based on the capabilities of the current platform, so the user still needs to be careful in their .git/config file.
16b83019	2012-03-04T23:28:36	Fix usage of "new" for fieldname in public header This should restore the ability to include libgit2 headers in C++ projects. Cherry picked 2de60205dfea2c4a422b2108a5e8605f97c2e895 from development into new-error-handling.
eb3d71a5	2012-04-25T22:23:35	diff: fix generation of the header of a removal patch
19fa2bc1	2012-04-17T15:12:50	Convert attrs and diffs to use string pools This converts the git attr related code (including ignores) and the git diff related code (and implicitly the status code) to use `git_pools` for storing strings. This reduces the number of small blocks allocated dramatically.
14a513e0	2012-04-13T15:00:29	Add support for pathspec to diff and status This adds preliminary support for pathspecs to diff and status. The implementation is not very optimized (it still looks at every single file and evaluated the the pathspec match against them), but it works.
95dfb031	2012-03-30T14:40:50	Improve config handling for diff,submodules,attrs This adds support for a bunch of core.* settings that affect diff and status, plus fixes up some incorrect implementations of those settings from before. Also, this cleans up the handling of config settings in the new submodules code and in the old attrs/ignore code.
1db12b00	2012-03-25T23:04:26	Eliminate hairy COITERATE macro I decided that the COITERATE macro was, in the end causing more confusion that it would save and decided just to write out the loops that I needed for parallel diff list iteration. It is not that much code and this just feels less obfuscated.
a48ea31d	2012-03-21T12:33:09	Reimplment git_status_foreach using git diff This is an initial reimplementation of status using diff a la the way that core git does it.
74fa4bfa	2012-02-28T16:14:47	Update diff to use iterators This is a major reorganization of the diff code. This changes the diff functions to use the iterators for traversing the content. This allowed a lot of code to be simplified. Also, this moved the functions relating to outputting a diff into a new file (diff_output.c). This includes a number of other changes - adding utility functions, extending iterators, etc. plus more tests for the diff code. This also takes the example diff.c program much further in terms of emulating git-diff command line options.
e47329b6	2012-02-13T17:29:30	First pass of diff index to workdir implementation This is an initial version of git_diff_workdir_to_index. It also includes renaming some structures and some refactoring of the existing code so that it could be shared better with the new function. This is not complete since it needs a rebase to get some new odb functions from the upstream branch.
a2e895be	2012-02-07T12:14:28	Continue implementation of git-diff * Implemented git_diff_index_to_tree * Reworked git_diff_options structure to handle more options * Made most of the options in git_diff_options actually work * Reorganized code a bit to remove some redundancy * Added option parsing to examples/diff.c to test most options
65b09b1d	2012-02-02T18:03:43	Implement diff lists and formatters This reworks the diff API to separate the steps of producing a diff descriptions from formatting the diff. This will allow us to share diff output code with the various diff creation scenarios and will allow us to implement rename detection as an optional pass that can be run on a diff list.
