Russell Belfer 5fdc41e7 2012-08-22T13:57:57 Minor bug fixes in diff code In looking at PR #878, I found a few small bugs in the diff code, mostly related to work that can be avoided when processing tree- to-tree diffs that was always being carried out. This commit has some small fixes in it.

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`.
nulltoken 9a29f8d5 2012-05-04T07:55:09 diff: fix the diffing of two identical blobs
nulltoken 28ef7f9b 2012-05-03T17:25:01 diff: make git_diff_blobs() able to detect binary blobs
nulltoken 2de0652b 2012-04-30T07:41:33 Leverage GIT_UNUSED macro to explicitly mark a function parameter as purposely unused
nulltoken 1d2dd864 2012-04-29T19:42:51 diff: provide more context to the consumer of the callbacks Update the callback to provide some information related to the file change being processed and the range of the hunk, when applicable.

Russell Belfer e1bcc191 2012-03-01T11:45:00 Revert GIT_STATUS constants to avoid issues This reverts the changes to the GIT_STATUS constants and adds a new enumeration to describe the type of change in a git_diff_delta. I don't love this solution, but it should prevent strange errors from occurring for now. Eventually, I would like to unify the various status constants, but it needs a larger plan and I just wanted to eliminate this breakage quickly.
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.
Russell Belfer 760db29c 2012-02-21T15:09:04 Fixing unit tests post rebase Some changes that merged cleanly actually broke the unit tests, so this fixes them.
Russell Belfer caf71ec0 2012-02-07T15:30:18 Add tests and fix bugs for diff whitespace options Once I added tests for the whitespace handling options of diff, I realized that there were some bugs. This fixes those and adds the new tests into the test suite.
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.
Russell Belfer b6c93aef 2012-02-21T14:46:24 Uniform iterators for trees, index, and workdir This create a new git_iterator type of object that provides a uniform interface for iterating over the index, an arbitrary tree, or the working directory of a repository. As part of this, git ignore support was extended to support push and pop of directory-based ignore files as the working directory is being traversed (so the array of ignores does not have to be recreated at each directory during traveral). There are a number of other small utility functions in buffer, path, vector, and fileops that are included in this patch that made the iterator implementation cleaner.
