Russell Belfer 3b5f7954 2013-10-21T13:42:42 Create git_diff_line and extend git_diff_hunk Instead of having functions with so very many parameters to pass hunk and line data, this takes the existing git_diff_hunk struct and extends it with more hunk data, plus adds a git_diff_line. Those structs are used to pass back hunk and line data instead of the old APIs that took tons of parameters. Some work that was previously only being done for git_diff_patch creation (scanning the diff content for exact line counts) is now done for all callbacks, but the performance difference should not be noticable.
Russell Belfer 10672e3e 2013-10-15T15:10:07 Diff API cleanup This lays groundwork for separating formatting options from diff creation options. This groups the formatting flags separately from the diff list creation flags and reorders the options. This also tweaks some APIs to further separate code that uses patches from code that just looks at git_diffs.
Russell Belfer 3ff1d123 2013-10-11T14:51:54 Rename diff objects and split patch.h This makes no functional change to diff but renames a couple of the objects and splits the new git_patch (formerly git_diff_patch) into a new header file.
Ben Straub 5e96f316 2013-08-08T08:54:38 Merge pull request #1738 from libgit2/diff-patch-content-size Add API for getting at git_diff_patch->content_size
Russell Belfer 8dd8aa48 2013-07-26T10:28:57 Fix some warnings
Russell Belfer 69c66b55 2013-07-24T13:09:33 Don't do text diff unless content will be used
Russell Belfer 197b8966 2013-07-23T14:34:31 Add hunk/file headers to git_diff_patch_size This allows git_diff_patch_size to account for hunk headers and file headers in the returned size. This required some refactoring of the code that is used to print file headers so that it could be invoked by the git_diff_patch_size API. Also this increases the test coverage and fixes an off-by-one bug in the size calculation when newline changes happen at the end of the file.
Russell Belfer b4a4cf24 2013-07-22T16:07:56 Add git_diff_patch_size() API This adds a new API to get the size in bytes of the diffs in a git_diff_patch object.
Russell Belfer c67ff958 2013-06-27T07:38:27 Fix bug marking submodule diffs as unmodified There was a bug where submodules whose HEAD had not been moved were being marked as having an UNMODIFIED delta record instead of being left MODIFIED. This fixes that and fixes the tests to notice if a submodule has been incorrectly marked as UNMODIFIED.
Russell Belfer 74ded024 2013-06-17T17:03:34 Add "as_path" parameters to blob and buffer diffs This adds parameters to the four functions that allow for blob-to- blob and blob-to-buffer differencing (either via callbacks or by making a git_diff_patch object). These parameters let you say that filename we should pretend the blob has while doing the diff. If you pass NULL, there should be no change from the existing behavior, which is to skip using attributes for file type checks and just look at content. With the parameters, you can plug into the new diff driver functionality and get binary or non-binary behavior, plus function context regular expressions, etc. This commit also fixes things so that the git_diff_delta that is generated by these functions will actually be populated with the data that we know about the blobs (or buffers) so you can use it appropriately. It also fixes a bug in generating patches from the git_diff_patch objects created via these functions. Lastly, there is one other behavior change that may matter. If there is no difference between the two blobs, these functions no longer generate any diff callbacks / patches unless you have passed in GIT_DIFF_INCLUDE_UNMODIFIED. This is pretty natural, but could potentially change the behavior of existing usage.
Russell Belfer a1683f28 2013-06-14T16:18:04 More tests and bug fixes for status with rename This changes the behavior of the status RENAMED flags so that they will be combined with the MODIFIED flags if appropriate. If a file is modified in the index and also renamed, then the status code will have both the GIT_STATUS_INDEX_MODIFIED and INDEX_RENAMED bits set. If it is renamed but the OID has not changed, then just the GIT_STATUS_INDEX_RENAMED bit will be set. Similarly, the flags GIT_STATUS_WT_MODIFIED and GIT_STATUS_WT_RENAMED can both be set independently of one another. This fixes a serious bug where the check for unmodified files that was done at data load time could end up erasing the RENAMED state of a file that was renamed with no changes. Lastly, this contains a bunch of new tests for status with renames, including tests where the only rename changes are case changes. The expected results of these tests have to vary by whether the platform uses a case sensitive filesystem or not, so the expected data covers those platform differences separately.
Russell Belfer 360f42f4 2013-06-12T14:18:09 Fix diff header naming issues This makes the git_diff_patch definition private to diff_patch.c and fixes a number of other header file naming inconsistencies to use `git_` prefixes on functions and structures that are shared between files.
Russell Belfer ef3374a8 2013-06-12T13:46:44 Improvements to git_array This changes the size data to uint32_t, fixes the array growth logic to use a simple 1.5x multiplier, and uses a generic inline function for growing the array to make the git_array_alloc API feel more natural (i.e. it returns a pointer to the new item).
Russell Belfer f9c824c5 2013-06-12T11:55:27 Add patch from blobs API This adds two new public APIs: git_diff_patch_from_blobs and git_diff_patch_from_blob_and_buffer, plus it refactors the code for git_diff_blobs and git_diff_blob_to_buffer so that they code is almost entirely shared between these APIs, and adds tests for the new APIs.
Russell Belfer 5dc98298 2013-06-11T11:22:22 Implement regex pattern diff driver This implements the loading of regular expression pattern lists for diff drivers that search for function context in that way. This also changes the way that diff drivers update options and interface with xdiff APIs to make them a little more flexible.
Russell Belfer 114f5a6c 2013-06-10T10:10:39 Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.
