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 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 960a04dd 2013-02-21T12:40:33 Initial integration of similarity metric to diff This is the initial integration of the similarity metric into the `git_diff_find_similar()` code path. The existing tests all pass, but the new functionality isn't currently well tested. The integration does go through the pluggable metric interface, so it should be possible to drop in an alternative to the internal metric that libgit2 implements. This comes along with a behavior change for an existing interface; namely, passing two NULLs to git_diff_blobs (or passing NULLs to git_diff_blob_to_buffer) will now call the file_cb parameter zero times instead of one time. I know it's strange that that change is paired with this other change, but it emerged from some initialization changes that I ended up making.

Russell Belfer f2b7f7a6 2013-01-07T15:44:22 Share git_diff_blobs/git_diff_blob_to_buffer code This moves the implementation of these two APIs into common code that will be shared between the two. Also, this adds tests for the `git_diff_blob_to_buffer` API. Lastly, this adds some extra `const` to a few places that can use it.

Russell Belfer 793c4385 2012-11-20T16:36:06 Update diff callback param order This makes the diff functions that take callbacks both take the payload parameter after the callback function pointers and pass the payload as the last argument to the callback function instead of the first. This should make them consistent with other callbacks across the API.

Sascha Cunz 9094d30b 2012-11-23T11:41:56 Reset all static variables to NULL in clar's __cleanup Without this change, any failed assertion in the second (or a later) test inside a test suite has a chance of double deleting memory, resulting in a heap corruption. See #1096 for details. This leaves alone the test cases where we "just" use cl_git_sandbox_init() and cl_git_sandbox_cleanup(). These methods already take good care to not double delete a repository. Fixes #1096
Russell Belfer 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.
Russell Belfer 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.

Russell Belfer 854eccbb 2012-02-29T12:04:59 Clean up GIT_UNUSED macros on all platforms It turns out that commit 31e9cfc4cbcaf1b38cdd3dbe3282a8f57e5366a5 did not fix the GIT_USUSED behavior on all platforms. 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.
Russell Belfer 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
Russell Belfer 3a437590 2012-02-03T16:53:01 Clean up diff implementation for review This fixes several bugs, updates tests and docs, eliminates the FILE* assumption in favor of printing callbacks for the diff patch formatter helpers, and adds a "diff" example function that can perform a diff from the command line.
