6e5c4af0	2012-05-17T14:21:10	Fix workdir iterators on empty directories Creating a workdir iterator on a directory with absolutely no files was returning an error (GIT_ENOTFOUND) instead of an iterator for nothing. This fixes that and includes two new tests that cover that case.

41a82592	2012-05-15T14:17:39	Ranged iterators and rewritten git_status_file The goal of this work is to rewrite git_status_file to use the same underlying code as git_status_foreach. This is done in 3 phases: 1. Extend iterators to allow ranged iteration with start and end prefixes for the range of file names to be covered. 2. Improve diff so that when there is a pathspec and there is a common non-wildcard prefix of the pathspec, it will use ranged iterators to minimize excess iteration. 3. Rewrite git_status_file to call git_status_foreach_ext with a pathspec that covers just the one file being checked. Since ranged iterators underlie the status & diff implementation, this is actually fairly efficient. The workdir iterator does end up loading the contents of all the directories down to the single file, which should ideally be avoided, but it is pretty good.
7e000ab2	2012-05-08T15:03:59	Add support for diffing index with no HEAD When a repo is first created, there is no HEAD yet and attempting to diff files in the index was showing nothing because a tree iterator could not be constructed. This adds an "empty" iterator and falls back on that when the head cannot be looked up.
bfc9ca59	2012-03-28T16:45:36	Added submodule API and use in status When processing status for a newly checked out repo, it is possible that there will be submodules that have not yet been initialized. The only way to distinguish these from untracked directories is to have some knowledge of submodules. This commit adds a new submodule API which, given a name or path, can determine if it appears to be a submodule and can give information about the submodule.
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.
66142ae0	2012-03-22T10:44:36	New status fixes This adds support for roughly-right tracking of submodules (although it does not recurse into submodules to detect internal modifications a la core git), and it adds support for including unmodified files in diff iteration if requested.
7c7ff7d1	2012-03-19T16:10:11	Migrate index, oid, and utils to new errors This includes a few cleanups that came up while converting these files. This commit introduces a could new git error classes, including the catchall class: GITERR_INVALID which I'm using as the class for invalid and out of range values which are detected at too low a level of library to use a higher level classification. For example, an overflow error in parsing an integer or a bad letter in parsing an OID string would generate an error in this class.

deafee7b	2012-03-14T17:36:15	Continue error conversion This converts blob.c, fileops.c, and all of the win32 files. Also, various minor cleanups throughout the code. Plus, in testing the win32 build, I cleaned up a bunch (although not all) of the warnings with the 64-bit build.

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.

0534641d	2012-02-22T15:15:35	Fix iterators based on pull request feedback This update addresses all of the feedback in pull request #570. The biggest change was to create actual linked list stacks for storing the tree and workdir iterator state. This cleaned up the code a ton. Additionally, all of the static functions had their 'git_' prefix removed, and a lot of other unnecessary changes were removed from the original patch.
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.
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.
