Carlos Martín Nieto 2086e1ba 2013-01-11T16:54:57 tests: plug a couple of leaks
Russell Belfer de590550 2013-01-08T17:11:11 Resolve crash with diff against empty file It is not legal inside our `p_mmap` function to mmap a zero length file. This adds a test that exercises that case inside diff and fixes the code path where we would try to do that. The fix turns out not to be a lot of code since our default file content is already initialized to "" which works in this case. Fixes #1210
Russell Belfer 56c72b75 2012-12-17T11:00:53 Fix diff constructor name order confusion The diff constructor functions had some confusing names, where the "old" side of the diff was coming after the "new" side. This reverses the order in the function name to make it less confusing. Specifically... * git_diff_index_to_tree becomes git_diff_tree_to_index * git_diff_workdir_to_index becomes git_diff_index_to_workdir * git_diff_workdir_to_tree becomes git_diff_tree_to_workdir

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.

Russell Belfer 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.
Russell Belfer 5735bf5e 2012-11-13T13:58:29 Fix diff API to better parameter order The diff API is not in the parameter order one would expect from other libgit2 APIs. This fixes that.
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.
nulltoken c2e43fb1 2012-10-18T16:50:55 diff: workdir diffing in a bare repo returns EBAREREPO
Russell Belfer 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.
Russell Belfer 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!
Russell Belfer 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.
Russell Belfer 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.
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 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`.
Russell Belfer 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.
Adam Roben 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.
Russell Belfer 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.
Russell Belfer 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.
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 c19bc93c 2012-02-29T14:19:39 Fixing memory leaks indicated by valgrind This clears up the memory leaks that valgrind seems to find on my machine.
Russell Belfer 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.
