d730d3f4	2013-07-31T16:40:42	Major rename detection changes After doing further profiling, I found that a lot of time was being spent attempting to insert hashes into the file hash signature when using the rolling hash because the rolling hash approach generates a hash per byte of the file instead of one per run/line of data. To optimize this, I decided to convert back to a run-based file signature algorithm which would be more like core Git. After changing this, a number of the existing tests started to fail. In some cases, this appears to have been because the test was coded to be too specific to the particular results of the file similarity metric and in some cases there appear to have been bugs in the core rename detection code where only by the coincidence of the file similarity scoring were the expected results being generated. This renames all the variables in the core rename detection code to be more consistent and hopefully easier to follow which made it a bit easier to reason about the behavior of that code and fix the problems that I was seeing. I think it's in better shape now. There are a couple of tests now that attempt to stress test the rename detection code and they are quite slow. Most of the time is spent setting up the test data on disk and in the index. When we roll out performance improvements for index insertion, it should also speed up these tests I hope.
f9775a37	2013-06-29T23:22:31	Add ignore_submodules to diff options This adds correct support for an equivalent to --ignore-submodules in diff, where an actual ignore value can be passed to diff to override the per submodule settings in the configuration. This required tweaking the constants for ignore values so that zero would not be used and could represent an unset option to the diff. This was an opportunity to move the submodule values into include/git2/types.h and to rename the poorly named DEFAULT values for ignore and update constants to RESET instead. Now the GIT_DIFF_IGNORE_SUBMODULES flag is exactly the same as setting the ignore_submodules option to GIT_SUBMODULE_IGNORE_ALL (which is actually a minor change from the old behavior in that submodules will now be treated as UNMODIFIED deltas instead of being left out totally - if you set GIT_DIFF_INCLUDE_UNMODIFIED). This includes tests for the various new settings.
1f9e41ee	2013-05-10T07:50:53	Improve ignore handling in git_status_file The git_status_file API was doing a hack to deal with files that are inside ignored directories. The status scan was not reporting any file in this case, so git_status_file would attempt a final "stat()" call, and return IGNORED if the file actually existed. On case-insensitive filesystems where core.ignorecase is set incorrectly, this magic check can "succeed" and report a file as ignored when it should actually return ENOTFOUND. Now that we have the GIT_STATUS_OPT_RECURSE_IGNORED_DIRS, we can use that flag to make sure that git_status_file() will look into ignored directories and eliminate the hack completely, so we give the correct error.
1323c6d1	2013-03-22T14:27:56	Add cl_repo_set_bool and cleanup tests This adds a helper function for the cases where you want to quickly set a single boolean config value for a repository. This allowed me to remove a lot of code.
3ba01362	2013-03-20T11:46:03	Update cl_assert_equal_sz to be nicer This makes the size_t comparison test nicer (assuming that the values are actually not using the full length), and converts some cases that were using it for pointer comparison to use the macro that is designed for pointer comparison.
e9e20c84	2012-12-19T14:52:12	Update cl_git_pass to return more info This adds a failure reporting function that is called by cl_git_pass which captures the actual error return code and the error message if available in the failure report.

da825c92	2012-06-19T14:27:02	Make index add/append support core.filemode flag This fixes git_index_add and git_index_append to behave more like core git, preserving old filemode data in the index when adding and/or appending with core.filemode = false. This also has placeholder support for core.symlinks and core.ignorecase, but those flags are not implemented (well, symlinks has partial support for preserving mode information in the same way that git does, but it isn't tested).
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.

7784bcbb	2012-04-11T11:52:59	Refactor git_repository_open with new options Add a new command `git_repository_open_ext` with extended options that control how searching for a repository will be done. The existing `git_repository_open` and `git_repository_discover` are reimplemented on top of it. We may want to change the default behavior of `git_repository_open` but this commit does not do that. Improve support for "gitdir" files where the work dir is separate from the repo and support for the "separate-git-dir" config. Also, add support for opening repos created with `git-new-workdir` script (although I have only confirmed that they can be opened, not that all functions work correctly). There are also a few minor changes that came up: - Fix `git_path_prettify` to allow in-place prettifying. - Fix `git_path_root` to support backslashes on Win32. This fix should help many repo open/discover scenarios - it is the one function called when opening before prettifying the path. - Tweak `git_config_get_string` to set the "out" pointer to NULL if the config value is not found. Allows some other cleanup. - Fix a couple places that should have been calling `git_repository_config__weakptr` and were not. - Fix `cl_git_sandbox_init` clar helper to support bare repos.
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.
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.
