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.

5d1308f2	2012-10-08T15:19:00	Add test for diffs with submodules and bug fixes The adds a test for the submodule diff capabilities and then fixes a few bugs with how the output is generated. It improves the accuracy of OIDs in the diff delta object and makes the submodule output more closely mirror the OIDs that will be used by core git.
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!
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.
49d34c1c	2012-09-13T13:17:38	Fix problems in diff iterator record chaining There is a bug in building the linked list of line records in the diff iterator and also an off by one element error in the hunk counts. This fixes both of these, adds some test data with more complex sets of hunk and line diffs to exercise this code better.
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.

145e696b	2012-06-08T11:56:24	Minor fixes, cleanups, and clarifications There are three actual changes in this commit: 1. When the trailing newline of a file is removed in a diff, the change will now be reported with `GIT_DIFF_LINE_DEL_EOFNL` passed to the callback. Previously, the `ADD_EOFNL` constant was given which was just an error in my understanding of when the various circumstances arose. `GIT_DIFF_LINE_ADD_EOFNL` is deprecated and should never be generated. A new newline is simply an `ADD`. 2. Rewrote the `diff_delta__merge_like_cgit` function that contains the core logic of the `git_diff_merge` implementation. The new version doesn't actually have significantly different behavior, but the logic should be much more obvious, I think. 3. Fixed a bug in `git_diff_merge` where it freed a string pool while some of the string data was still in use. This led to `git_diff_print_patch` accessing memory that had been freed. The rest of this commit contains improved documentation in `diff.h` to make the behavior and the equivalencies with core git clearer, and a bunch of new tests to cover the various cases, oh and a minor simplification of `examples/diff.c`.
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.
8e60c712	2012-06-07T09:50:19	Fix git_status_file for files that start with a character > 0x7f git_status_file would always return GIT_ENOTFOUND for these files. The underlying bug was that git__strcmp_cb, which is used by git_path_with_stat_cmp to sort entries in the working directory, compares strings based on unsigned chars (this is confirmed by the strcmp(3) manpage), while git__prefixcmp, which is used by workdir_iterator__entry_cmp to search for a path in the working directory, compares strings based on char. So the sort puts this path at the end of the list, while the search expects it to be at the beginning. The fix was simply to make git__prefixcmp compare using unsigned chars, just like strcmp(3). The rest of the change is just adding/updating tests.
1a6e8f8a	2012-04-13T10:42:00	Update clar and remove old helpers This updates to the latest clar which includes the helpers `cl_assert_equal_s` and `cl_assert_equal_i`. Convert the code over to use those and remove the old libgit2-only helpers.
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.

This commit walks through and really cleans things up more thoroughly, getting rid of the unnecessary stuff. To remove the use of some GIT_UNUSED, I ended up adding a couple of new iterators for hashtables that allow you to iterator just over keys or just over values. In making this change, I found a bug in the clar tests (where we were doing count++ but meant to do (count)++ to increment the value). I fixed that but then found the test failing because it was not really using an empty repo. So, I took some of the code that I wrote for iterator testing and moved it to clar_helpers.c, then made use of that to make it easier to open fixtures on a per test basis even within a single test file.
