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 875bfc5f 2012-03-25T21:26:48 Fix error in tree iterator when popping up trees There was an error in the tree iterator where it would delete two tree levels instead of just one when popping up a tree level. Unfortunately the test data for the tree iterator did not have any deep trees with subtrees in the middle of the tree items, so this problem went unnoticed. This contains the 1-line fix plus new test data and tests that reveal the issue.
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 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 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 f01fa266 2012-02-23T11:17:48 Fix workdir iterator unit tests This test is fragile if you leave extra files in the test data directory, such as a foo.c~ file from editing with Emacs. Who would do such a thing?
Russell Belfer da337c80 2012-02-22T11:22:33 Iterator improvements from diff implementation This makes two changes to iterator behavior: first, advance can optionally do the work of returning the new current value. This is such a common pattern that it really cleans up usage. Second, for workdir iterators, this removes automatically iterating into directories. That seemed like a good idea, but when an entirely new directory hierarchy is introduced into the workdir, there is no reason to iterate into it if there are no corresponding entries in the tree/index that it is being compared to. This second change actually wasn't a lot of code because not descending into directories was already the behavior for ignored directories. This just extends that to all directories.
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.
