ba084f7a	2012-12-17T11:03:42	More diff.h comment fixes Based on feedback from the ObjectiveGit folks, these are some further updates to diff.h areas that are poorly documented.
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

This should make them consistent with other callbacks across the API.

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.
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.
1362a983	2012-11-02T10:00:28	Merge pull request #1014 from arrbee/diff-rename-detection Initial implementation of diff rename detection
db106d01	2012-10-30T09:40:50	Move rename detection into new file This improves the naming for the rename related functionality moving it to be called `git_diff_find_similar()` and renaming all the associated constants, etc. to make more sense. I also moved the new code (plus the existing `git_diff_merge`) into a new file `diff_tform.c` where I can put new functions related to manipulating git diff lists. This also updates the implementation significantly from the last revision fixing some ordering issues (where break-rewrite needs to be handled prior to copy and rename detection) and improving config option handling.
cb7180a6	2012-10-25T11:48:39	Add git_diff_patch_print This adds a `git_diff_patch_print()` API which is more like the existing API to "print" a patch from an entire `git_diff_list` but operates on a single `git_diff_patch` object. Also, it rewrites the `git_diff_patch_to_str()` API to use that function (making it very small).
93cf7bb8	2012-10-24T20:56:32	Add git_diff_patch_to_str API This adds an API to generate a complete single-file patch text from a git_diff_patch object.
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.
fe67e404	2012-10-09T14:35:24	Move enum comments next to actual values
0d64bef9	2012-10-05T15:56:57	Add complex checkout test and then fix checkout This started as a complex new test for checkout going through the "typechanges" test repository, but that revealed numerous issues with checkout, including: * complete failure with submodules * failure to create blobs with exec bits * problems when replacing a tree with a blob because the tree "example/" sorts after the blob "example" so the delete was being processed after the single file blob was created This fixes most of those problems and includes a number of other minor changes that made it easier to do that, including improving the TYPECHANGE support in diff/status, etc.
95f5f1e6	2012-10-02T13:57:15	Cleanup TYPECHANGE support This is just some cleanup code, rearranging some of the checkout code where TYPECHANGE support was added and adding some comments to the diff header regarding the constants.
bc16fd3e	2012-09-28T13:40:02	Introduce status/diff TYPECHANGE flags When I wrote the diff code, I based it on core git's diff output which tends to split a type change into an add and a delete. But core git's status has the notion of a T (typechange) flag for a file. This introduces that into our status APIs and modifies the diff code so it can be forced to not split type changes.
dfbff793	2012-10-08T15:14:12	Fix a few diff bugs with directory content There are a few cases where diff should leave directories in the diff list if we want to match core git, such as when the directory contains a .git dir. That feature was lost when I introduced some of the new submodule handling. This restores that and then fixes a couple of related to diff output that are triggered by having diffs with directories in them. Also, this adds a new flag that can be passed to diff if you want diff output to actually include the file content of any untracked files.
eada0762	2012-10-02T10:45:40	Merge pull request #939 from pwkelley/ignorecase Support for the core.ignorecase flag
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!
64286308	2012-09-25T10:48:50	Fix bugs in new diff patch code This fixes all the bugs in the new diff patch code. The only really interesting one is that when we merge two diffs, we now have to actually exclude diff delta records that are not supposed to be tracked, as opposed to before where they could be included because they would be skipped silently by `git_diff_foreach()`. Other than that, there are just minor errors.
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.
9a12a625	2012-09-18T15:13:07	New take on iterating over diff content Allow diff deltas to be accessed by index and make patch generation explicit with hunk and line access by index as well.
ec40b7f9	2012-09-17T15:42:41	Support for core.ignorecase
1f35e89d	2012-09-11T12:03:33	Fix diff binary file detection In the process of adding tests for the max file size threshold (which treats files over a certain size as binary) there seem to be a number of problems in the new code with detecting binaries. This should fix those up, as well as add a test for the file size threshold stuff. Also, this un-deprecates `GIT_DIFF_LINE_ADD_EOFNL`, since I finally found a legitimate situation where it would be returned.
e597b189	2012-09-10T11:49:12	Move diff max_size to public API This commit adds a max_size value in the public `git_diff_options` structure so that the user can automatically flag blobs over a certain size as binary regardless of other properties. Also, and perhaps more importantly, this moves binary detection to be as early as possible in the diff traversal inner loop and makes sure that we stop loading objects as soon as we decide that they are binary.
b36effa2	2012-09-10T09:59:14	Replace git_diff_iterator_num_files with progress The `git_diff_iterator_num_files` API was problematic, since we don't actually know the exact number of files to be iterated over until we load those files into memory. This replaces it with a new `git_diff_iterator_progress` API that goes from 0 to 1, and moves and renamed the old API for the internal places that can tolerate a max value instead of an exact value.

01ae1909	2012-09-06T10:13:38	diff: Cleanup documentation and printf compat
510f1bac	2012-08-30T16:39:05	Fix comments and a minor bug This adds better header comments and also fixes a bug in one of simple APIs that tells the number of lines in the current hunk.
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.
5f4a61ae	2012-08-09T19:43:25	Working implementation of git_submodule_status This is a big redesign of the git_submodule_status API and the implementation of the redesigned API. It also fixes a number of bugs that I found in other parts of the submodule API while writing the tests for the status part. This also fixes a couple of bugs in the iterators that had not been noticed before - one with iterating when there is a gitlink (i.e. separate-work-dir) and one where I was treating anything even vaguely submodule-like as a submodule, more aggressively than core git does.
5dca2010	2012-08-03T17:08:01	Update iterators for consistency across library This updates all the `foreach()` type functions across the library that take callbacks from the user to have a consistent behavior. The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules.

29f9186d	2012-07-02T11:18:01	diff: make inter-hunk-context default value git-compliant Default in git core is 0, not 3
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`.

16b83019	2012-03-04T23:28:36	Fix usage of "new" for fieldname in public header This should restore the ability to include libgit2 headers in C++ projects. Cherry picked 2de60205dfea2c4a422b2108a5e8605f97c2e895 from development into new-error-handling.
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.
4b136a94	2012-03-23T09:26:09	Fix crash in new status and add recurse option This fixes the bug that @nulltoken found (thank you!) where if there were untracked directories alphabetically after the last tracked item, the diff implementation would deref a NULL pointer. The fix involved the code which decides if it is necessary to recurse into a directory in the working dir, so it was easy to add a new option `GIT_STATUS_OPT_RECURSE_UNTRACKED_DIRS` to control if the contents of untracked directories should be included in status.
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.

2de60205	2012-03-04T23:28:36	Fix usage of "new" for fieldname in public header This should restore the ability to include libgit2 headers in C++ projects.
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.
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.
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
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.
65b09b1d	2012-02-02T18:03:43	Implement diff lists and formatters This reworks the diff API to separate the steps of producing a diff descriptions from formatting the diff. This will allow us to share diff output code with the various diff creation scenarios and will allow us to implement rename detection as an optional pass that can be run on a diff list.
cd33323b	2012-01-27T11:29:25	Initial implementation of git_diff_blob This gets the basic plumbing in place for git_diff_blob. There is a known issue where additional parameters like the number of lines of context to display on the diff are not working correctly (which leads one of the new unit tests to fail).

Move diff max_size to public API This commit adds a max_size value in the public `git_diff_options` structure so that the user can automatically flag blobs over a certain size as binary regardless of other properties. Also, and perhaps more importantly, this moves binary detection to be as early as possible in the diff traversal inner loop and makes sure that we stop loading objects as soon as we decide that they are binary.

Replace git_diff_iterator_num_files with progress The `git_diff_iterator_num_files` API was problematic, since we don't actually know the exact number of files to be iterated over until we load those files into memory. This replaces it with a new `git_diff_iterator_progress` API that goes from 0 to 1, and moves and renamed the old API for the internal places that can tolerate a max value instead of an exact value.

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.

Working implementation of git_submodule_status This is a big redesign of the git_submodule_status API and the implementation of the redesigned API. It also fixes a number of bugs that I found in other parts of the submodule API while writing the tests for the status part. This also fixes a couple of bugs in the iterators that had not been noticed before - one with iterating when there is a gitlink (i.e. separate-work-dir) and one where I was treating anything even vaguely submodule-like as a submodule, more aggressively than core git does.

Update iterators for consistency across library This updates all the `foreach()` type functions across the library that take callbacks from the user to have a consistent behavior. The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules.

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`.

Fix crash in new status and add recurse option This fixes the bug that @nulltoken found (thank you!) where if there were untracked directories alphabetically after the last tracked item, the diff implementation would deref a NULL pointer. The fix involved the code which decides if it is necessary to recurse into a directory in the working dir, so it was easy to add a new option `GIT_STATUS_OPT_RECURSE_UNTRACKED_DIRS` to control if the contents of untracked directories should be included in status.

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.

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.

Implement diff lists and formatters This reworks the diff API to separate the steps of producing a diff descriptions from formatting the diff. This will allow us to share diff output code with the various diff creation scenarios and will allow us to implement rename detection as an optional pass that can be run on a diff list.

Initial implementation of git_diff_blob This gets the basic plumbing in place for git_diff_blob. There is a known issue where additional parameters like the number of lines of context to display on the diff are not working correctly (which leads one of the new unit tests to fail).
