2b672d5b	2013-07-08T22:46:36	Add git_pathspec_match_diff API This adds an additional pathspec API that will match a pathspec against a diff object. This is convenient if you want to handle renames (so you need the whole diff and can't use the pathspec constraint built into the diff API) but still want to tell if the diff had any files that matched the pathspec. When the pathspec is matched against a diff, instead of keeping a list of filenames that matched, instead the API keeps the list of git_diff_deltas that matched and they can be retrieved via a new API git_pathspec_match_list_diff_entry. There are a couple of other minor API extensions here that were mostly for the sake of convenience and to reduce dependencies on knowing the internal data structure between files inside the library.
a5f9b5f8	2013-07-05T16:59:38	Diff hunk context off by one on long lines The diff hunk context string that is returned to xdiff need not be NUL terminated because the xdiff code just copies the number of bytes that you report directly into the output. There was an off by one in the diff driver code when the header context was longer than the output buffer size, the output buffer length included the NUL byte which was copied into the hunk header. Fixes #1710

c67ff958	2013-06-27T07:38:27	Fix bug marking submodule diffs as unmodified There was a bug where submodules whose HEAD had not been moved were being marked as having an UNMODIFIED delta record instead of being left MODIFIED. This fixes that and fixes the tests to notice if a submodule has been incorrectly marked as UNMODIFIED.

94ef2a35	2013-06-20T15:15:10	Add test for fixed diff bug Add test for bug fixed in 852ded96982ae70acb63c3940fae08ea29e40fee Sorry, I wrote that bug fix and forgot to check in a test at the same time. Here is one that fails on the old version of the code and now works.
e4acc3ba	2013-06-18T16:14:35	Fix rename looped reference issues This makes the diff rename tracking code more careful about the order in which it processes renames and more thorough in updating the mapping of correct renames when an earlier rename update alters the index of a later matched pair.

74ded024	2013-06-17T17:03:34	Add "as_path" parameters to blob and buffer diffs This adds parameters to the four functions that allow for blob-to- blob and blob-to-buffer differencing (either via callbacks or by making a git_diff_patch object). These parameters let you say that filename we should pretend the blob has while doing the diff. If you pass NULL, there should be no change from the existing behavior, which is to skip using attributes for file type checks and just look at content. With the parameters, you can plug into the new diff driver functionality and get binary or non-binary behavior, plus function context regular expressions, etc. This commit also fixes things so that the git_diff_delta that is generated by these functions will actually be populated with the data that we know about the blobs (or buffers) so you can use it appropriately. It also fixes a bug in generating patches from the git_diff_patch objects created via these functions. Lastly, there is one other behavior change that may matter. If there is no difference between the two blobs, these functions no longer generate any diff callbacks / patches unless you have passed in GIT_DIFF_INCLUDE_UNMODIFIED. This is pretty natural, but could potentially change the behavior of existing usage.
de0555a3	2013-06-17T09:55:29	Fix memory leaks in diff rename tests This fixes a couple objects I forgot to free, and also updates the valgrind suppressions file on the Mac to cover a few more cases that had crept in.
f3b5bc83	2013-06-16T21:51:43	Add test of rename with no changes A tree to index rename with no changes was getting erased by the iteration routine (if the routine actually loaded the data for the unmodified file). This invokes the code path that was previously messing up the diff and iterates twice to make sure that the iteration process itself doesn't modify the data.
6ea999bb	2013-06-13T15:52:12	Make index_insert keep existing case In a case insensitive index, if you attempt to add a file from disk with a different case pattern, the old case pattern in the index should be preserved. This fixes that (and a couple of minor warnings).

f9c824c5	2013-06-12T11:55:27	Add patch from blobs API This adds two new public APIs: git_diff_patch_from_blobs and git_diff_patch_from_blob_and_buffer, plus it refactors the code for git_diff_blobs and git_diff_blob_to_buffer so that they code is almost entirely shared between these APIs, and adds tests for the new APIs.
54faddd2	2013-06-12T11:54:11	Fix some diff driver memory leaks
42e6cf78	2013-06-11T17:45:14	Add diff drivers tests (and fix bugs) This adds real tests for user-configured diff drivers and in the process found a bunch of bugs.
5dc98298	2013-06-11T11:22:22	Implement regex pattern diff driver This implements the loading of regular expression pattern lists for diff drivers that search for function context in that way. This also changes the way that diff drivers update options and interface with xdiff APIs to make them a little more flexible.
bda3fbb1	2013-06-10T14:17:54	failing unit test for similar renames
114f5a6c	2013-06-10T10:10:39	Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.
cee695ae	2013-05-31T12:18:43	Make iterators use GIT_ITEROVER & smart advance 1. internal iterators now return GIT_ITEROVER when you go past the last item in the iteration. 2. git_iterator_advance will "advance" to the first item in the iteration if it is called immediately after creating the iterator, which allows a simpler idiom for basic iteration. 3. if git_iterator_advance encounters an error reading data (e.g. a missing tree or an unreadable file), it returns the error but also attempts to advance past the invalid data to prevent an infinite loop. Updated all tests and internal usage of iterators to account for these new behaviors.
49f70f2c	2013-05-23T15:48:06	Fill out diff rename test coverage This extends the rename tests to make sure that every rename scenario in the inner loop of git_diff_find_similar is actually exercised. Also, fixes an incorrect assert that was in one of the clauses that was not previously being exercised.
67db583d	2013-05-23T15:06:07	More diff rename tests; better split swap handling This adds a couple more tests of different rename scenarios. Also, this fixes a problem with the case where you have two "split" deltas and the left half of one matches the right half of the other. That case was already being handled, but in the wrong order in a way that could result in bad output. Also, if the swap also happened to put the other two halves into the correct place (i.e. two files exchanged places with each other), then the second delta was left with the SPLIT flag set when it really should be cleared.
a21cbb12	2013-05-22T10:37:12	Significant rename detection rewrite This flips rename detection around so instead of creating a forward mapping from deltas to possible rename targets, instead it creates a reverse mapping, looking at possible targets and trying to find a source that they could have been renamed or copied from. This is important because each output can only have a single source, but a given source could map to multiple outputs (in the form of COPIED records). Additionally, this makes a couple of tweaks to the public rename detection APIs, mostly renaming a couple of options that control the behavior to make more sense and to be more like core Git. I walked through the tests looking at the exact results and updated the expectations based on what I saw. The new code is different from the old because it cannot give some nonsense results (like A was renamed to both B and C) which were part of the outputs previously.
4742148d	2013-05-20T13:41:39	Add more diff rename detection tests This adds a bunch more rename detection tests including checks vs the working directory, the new exact match options, some more whitespace variants, etc. This also adds a git_futils_writebuffer helper function and uses it in checkout. This is mainly added because I wanted an easy way to write out a git_buf to disk inside my test code.
d958e37a	2013-05-17T17:21:45	Fix issues with git_diff_find_similar There are a number of bugs in the rename code that only were obvious when I started testing it against large old repos with more complex patterns. (The code to do that testing is not ready to merge with libgit2, but I do plan to add more thorough tests.) This contains a significant number of changes and also tweaks the public API slightly to make emulating core git easier. Most notably, this separates the GIT_DIFF_FIND_AND_BREAK_REWRITES flag into FIND_REWRITES (which adds a self-similarity score to every modified file) and BREAK_REWRITES (which splits the modified deltas into add/remove pairs in the diff list). When you do a raw output of core git, rewrites show up as M090 or such, not at A and D output, so I wanted to be able to emulate that. Publicly, this also changes the flags to be uint16_t since we don't need values out of that range. Internally, this contains significant changes from a number of small bug fixes (like using the wrong side of the diff to decide if the object could be found in the ODB vs the workdir) to larger issues about which files can and should be compared and how the various edge cases of similarity scores should be treated. Honestly, I don't think this is the last update that will have to be made to this code, but I think this moves us closer to correct behavior and I tried to document the code so it would be easier to follow..
79ef3be4	2013-05-15T14:50:05	Fix diff crash when last item is untracked dir When the last item in a diff was an untracked directory that only contained ignored items, the loop to scan the contents would run off the end of the iterator and dereference a NULL pointer. This includes a test that reproduces the problem and a fix.
b4d33e46	2013-05-14T21:54:26	Fix some memory leaks
e9ba61f3	2013-05-10T09:32:42	Fix diff output for renames and copies If you use rename detection, the renamed and copied files would not show any text diffs because the function that decides if data should be loaded didn't know which sides of the diff to load for those cases. This adds a test that looks at the patch generated for diff entries that are COPIED or RENAMED.
c2f602f8	2013-05-07T07:15:39	Fix line numbering for patches with eofnl When a patch contained an eofnl change (i.e. the last line either gained or lost a newline), the oldno and newno line number values for the lines in the last hunk of the patch were not useful. This makes them behave in a more expected manner.
fd96f98e	2013-05-07T04:36:42	More tests for files with no newline at end
e35e2684	2013-05-07T04:32:17	Add GIT_DIFF_LINE_CONTEXT_EOFNL This adds a new line origin constant for the special line that is used when both files end without a newline. In the course of writing the tests for this, I was having problems with modifying a file but not having diff notice because it was the same size and modified less than one second from the start of the test, so I decided to start working on nanosecond timestamp support. This commit doesn't contain the nanosecond support, but it contains the reorganization of maybe_modified and the hooks so that if the nanosecond data were being read by stat() (or rather being copied by git_index_entry__init_from_stat), then the nsec would be taken into account. This new stuff could probably use some more tests, although there is some amount of it here.
a66c4bc8	2013-04-29T02:57:01	More tests for diff untracked directories This includes more tests for various scenarios when diff includes an untracked directory in the workdir with contents either ignored or not.
b1ff7004	2013-04-22T16:25:57	Improve diff config options handling This makes diff use the cvar cache for config options where possible, and also adds support for a number of other config options to diff including "diff.context", "diff.ignoreSubmodules", "diff.noprefix", "diff.mnemonicprefix", and "core.abbrev". To make this natural, this involved a rearrangement of the code that allocates the diff object vs. the code that initializes it based on the combination of options passed in by the user and read from the config. This commit includes tests for most of these new options as well.

ad26434b	2013-04-09T14:52:32	Tests and more fixes for submodule diffs This adds tests for diffs with submodules in them and (perhaps unsurprisingly) requires further fixes to be made. Specifically, this fixes: - when considering if a submodule is dirty in the workdir, it was being treated as dirty even if only the index was dirty. - git_diff_patch_to_str (and git_diff_patch_print) were "printing" the headers for files (and submodules) that were unmodified or had no meaningful content. - added comment to previous fix and removed unneeded parens.
ccfa6805	2013-03-25T23:58:40	Fix some diff ignores and submodule dirty workdir This started out trying to look at the problems from issue #1425 and gradually grew to a broader set of fixes. There are two core things fixed here: 1. When you had an ignore like "/bin" which is rooted at the top of your tree, instead of immediately adding the "bin/" entry as an ignored item in the diff, we were returning all of the direct descendants of the directory as ignored items. This changes things to immediately ignore the directory. Note that this effects the behavior in test_status_ignore__subdirectories so that we no longer exactly match core gits ignore behavior, but the new behavior probably makes more sense (i.e. we now will include an ignored directory inside an untracked directory that we previously would have left off). 2. When a submodule only contained working directory changes, the diff code was always considering it unmodified which was just an outright bug. The HEAD SHA of the submodule matches the SHA in the parent repo index, and since the SHAs matches, the diff code was overwriting the actual status with UNMODIFIED. These fixes broke existing tests test_diff_workdir__submodules and test_status_ignore__subdirectories but looking it over, I actually think the new results are correct and the old results were wrong. @nulltoken had actually commented on the subdirectory ignore issue previously. I also included in the tests some debugging versions of the shared iteration callback routines that print status or diff information. These aren't used actively in the tests, but can be quickly swapped in to test code to give a better picture of what is being scanned in some of the complex test scenarios.
1098cfae	2013-03-22T14:52:29	Test fixes and cleanup This fixes some places where the new tests were leaving the test area in a bad state or were freeing data they should not free. It also removes code that is extraneous to the core issue and fixes an invalid SHA being looked up in one of the tests (which was failing, but for the wrong reason).
b8acb775	2013-03-07T22:15:40	Added some tests for issue #1397 Signed-off-by: Sven Strickroth <email@cs-ware.de>
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.
65025cb8	2013-03-18T17:24:13	Three submodule status bug fixes 1. Fix sort order problem with submodules where "mod" was sorting after "mod-plus" because they were being sorted as "mod/" and "mod-plus/". This involved pushing the "contains a .git entry" test significantly lower in the stack. 2. Reinstate behavior that a directory which contains a .git entry will be treated as a submodule during iteration even if it is not yet added to the .gitmodules. 3. Now that any directory containing .git is reported as submodule, we have to be more careful checking for GIT_EEXISTS when we do a submodule lookup, because that is the error code that is returned by git_submodule_lookup when you try to look up a directory containing .git that has no record in gitmodules or the index.

1aa5318a	2013-03-09T16:04:34	diff: allow asking for diffs with no context Previously, 0 meant default. This is problematic, as asking for 0 context lines is a valid thing to do. Change GIT_DIFF_OPTIONS_INIT to default to three and stop treating 0 as a magic value. In case no options are provided, make sure the options in the diff object default to 3.
9bea03ce	2013-03-06T15:16:34	Add INCLUDE_TREES, DONT_AUTOEXPAND iterator flags This standardizes iterator behavior across all three iterators (index, tree, and working directory). Previously the working directory iterator behaved differently from the other two. Each iterator can now operate in one of three modes: 1. No tree results, auto expand trees means that only non- tree items will be returned and when a tree/directory is encountered, we will automatically descend into it. 2. Tree results, auto expand trees means that results will be given for every item found, including trees, but you only need to call normal git_iterator_advance to yield every item (i.e. trees returned with pre-order iteration). 3. Tree results, no auto expand means that calling the normal git_iterator_advance when looking at a tree will not descend into the tree, but will skip over it to the next entry in the parent. Previously, behavior 1 was the only option for index and tree iterators, and behavior 3 was the only option for workdir. The main public API implications of this are that the `git_iterator_advance_into()` call is now valid for all iterators, not just working directory iterators, and all the existing uses of working directory iterators explicitly use the GIT_ITERATOR_DONT_AUTOEXPAND (for now). Interestingly, the majority of the implementation was in the index iterator, since there are no tree entries there and now have to fake them. The tree and working directory iterators only required small modifications.
169dc616	2013-03-05T16:10:05	Make iterator APIs consistent with standards The iterator APIs are not currently consistent with the parameter ordering of the rest of the codebase. This rearranges the order of parameters, simplifies the naming of a number of functions, and makes somewhat better use of macros internally to clean up the iterator code. This also expands the test coverage of iterator functionality, making sure that case sensitive range-limited iteration works correctly.
323bb885	2013-03-04T00:21:56	Fix a few leaks `git_diff_get_patch()` would unconditionally load the patch object and then simply leak it if the user hadn't requested it. Short-circuit loading the object if the user doesn't want it. The rest of the plugs are simply calling the free functions of objects allocated during the tests.
487fc724	2013-03-01T13:41:53	Allow empty config object and use it This removes assertions that prevent us from having an empty git_config object and then updates some tests that were dependent on global config state to use an empty config before running anything.

6f9d5ce8	2013-02-22T10:17:08	Fix tests for find_similar and related This fixes both a test that I broke in diff::patch where I was relying on the current state of the working directory for the renames test data and fixes an unstable test in diff::rename where the environment setting for the "diff.renames" config was being allowed to influence the test results.
d4b747c1	2013-02-21T16:44:44	Add diff rename tests with partial similarity This adds some new tests that actually exercise the similarity metric between files to detect renames, copies, and split modified files that are too heavily modified. There is still more testing to do - these tests are just partially covering the cases. There is also one bug fix in this where a change set with only MODIFY being broken into ADD/DELETE (due to low self-similarity) without any additional RENAMED entries would end up not processing the split requests (because the num_rewrites counter got reset).
960a04dd	2013-02-21T12:40:33	Initial integration of similarity metric to diff This is the initial integration of the similarity metric into the `git_diff_find_similar()` code path. The existing tests all pass, but the new functionality isn't currently well tested. The integration does go through the pluggable metric interface, so it should be possible to drop in an alternative to the internal metric that libgit2 implements. This comes along with a behavior change for an existing interface; namely, passing two NULLs to git_diff_blobs (or passing NULLs to git_diff_blob_to_buffer) will now call the file_cb parameter zero times instead of one time. I know it's strange that that change is paired with this other change, but it emerged from some initialization changes that I ended up making.
71a3d27e	2013-02-08T10:06:47	Replace diff delta binary with flags Previously the git_diff_delta recorded if the delta was binary. This replaces that (with no net change in structure size) with a full set of flags. The flag values that were already in use for individual git_diff_file objects are reused for the delta flags, too (along with renaming those flags to make it clear that they are used more generally). This (a) makes things somewhat more consistent (because I was using a -1 value in the "boolean" binary field to indicate unset, whereas now I can just use the flags that are easier to understand), and (b) will make it easier for me to add some additional flags to the delta object in the future, such as marking the results of a copy/rename detection or other deltas that might want a special indicator. While making this change, I officially moved some of the flags that were internal only into the private diff header. This also allowed me to remove a gross hack in rename/copy detect code where I was overwriting the status field with an internal value.

f1e2735c	2013-01-30T11:10:39	Add helper for diff line stats This adds a `git_diff_patch_line_stats()` API that gets the total number of adds, deletes, and context lines in a patch. This will make it a little easier to emulate `git diff --stat` and the like. Right now, this relies on generating the `git_diff_patch` object, which is a pretty heavyweight way to get stat information. At some future point, it would probably be nice to be able to get this information without allocating the entire `git_diff_patch`, but that's a much larger project.
cce548e3	2013-01-22T15:28:25	Fix case sensitivity bug with tree iterators With the new code to make tree iterators support ignore_case, there is a bug in setting the start entry for range bounded iterators where memcmp was being used instead of strncasecmp. This fixes that and expands the tree iterator test to cover the cases that were broken.
25423d03	2013-01-09T16:07:54	Support case insensitive tree iterators and status This makes tree iterators directly support case insensitivity by using a secondary index that can be sorted by icase. Also, this fixes the ambiguity check in the git_status_file API to also be case insensitive. Lastly, this adds new test cases for case insensitive range boundary checking for all types of iterators. With this change, it should be possible to deprecate the spool and sort iterator, but I haven't done that yet.
a49340c3	2013-01-08T15:56:11	Test for ignore_case ranges on workdir iterator This adds a test that confirms that the working directory iterator can actually correctly process ranges of files case insensitively with proper sorting and proper boundaries.
134d8c91	2013-01-08T15:53:13	Update iterator API with flags for ignore_case This changes the iterator API so that flags can be passed in to the constructor functions to control the ignore_case behavior. At this point, the flags are not supported on tree iterators (i.e. there is no functional change over the old API), but the API changes are all made to accomodate this. By the way, I went with a flags parameter because in the future I have a couple of other ideas for iterator flags that will make it easier to fix some diff/status/checkout bugs.
4b181037	2013-01-08T13:39:15	Minor iterator API cleanups In preparation for further iterator changes, this cleans up a few small things in the iterator API: * removed the git_iterator_for_repo_index_range API * made git_iterator_free not be inlined * minor param name and test function name tweaks
805c476c	2013-01-11T11:20:44	Fix diff patch line number calculation This was just wrong. Added a test that verifying patch line numbers even for hunks further into a file and then fixed the algorithm. I needed to add a little extra state into the patch so that I could track old and new file numbers independently, but it should be okay.

de590550	2013-01-08T17:11:11	Resolve crash with diff against empty file It is not legal inside our `p_mmap` function to mmap a zero length file. This adds a test that exercises that case inside diff and fixes the code path where we would try to do that. The fix turns out not to be a lot of code since our default file content is already initialized to "" which works in this case. Fixes #1210

Also, this adds tests for the `git_diff_blob_to_buffer` API. Lastly, this adds some extra `const` to a few places that can use it.

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

d46b0a04	2012-11-19T16:34:44	Improve iterator ignoring .git file The workdir iterator has always tried to ignore .git files, but it turns out there were some bugs. This makes it more robust at ignoring .git files. This also makes iterators always check ".git" case insensitively regardless of the properties of the system. This will make libgit2 skip ".GIT" and the like. This is different from core git, but on systems with case insensitive but case preserving file systems, allowing ".GIT" to be added is problematic.
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.

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.

Add git_pathspec_match_diff API This adds an additional pathspec API that will match a pathspec against a diff object. This is convenient if you want to handle renames (so you need the whole diff and can't use the pathspec constraint built into the diff API) but still want to tell if the diff had any files that matched the pathspec. When the pathspec is matched against a diff, instead of keeping a list of filenames that matched, instead the API keeps the list of git_diff_deltas that matched and they can be retrieved via a new API git_pathspec_match_list_diff_entry. There are a couple of other minor API extensions here that were mostly for the sake of convenience and to reduce dependencies on knowing the internal data structure between files inside the library.

Diff hunk context off by one on long lines The diff hunk context string that is returned to xdiff need not be NUL terminated because the xdiff code just copies the number of bytes that you report directly into the output. There was an off by one in the diff driver code when the header context was longer than the output buffer size, the output buffer length included the NUL byte which was copied into the hunk header.

Add "as_path" parameters to blob and buffer diffs This adds parameters to the four functions that allow for blob-to- blob and blob-to-buffer differencing (either via callbacks or by making a git_diff_patch object). These parameters let you say that filename we should pretend the blob has while doing the diff. If you pass NULL, there should be no change from the existing behavior, which is to skip using attributes for file type checks and just look at content. With the parameters, you can plug into the new diff driver functionality and get binary or non-binary behavior, plus function context regular expressions, etc. This commit also fixes things so that the git_diff_delta that is generated by these functions will actually be populated with the data that we know about the blobs (or buffers) so you can use it appropriately. It also fixes a bug in generating patches from the git_diff_patch objects created via these functions. Lastly, there is one other behavior change that may matter. If there is no difference between the two blobs, these functions no longer generate any diff callbacks / patches unless you have passed in GIT_DIFF_INCLUDE_UNMODIFIED. This is pretty natural, but could potentially change the behavior of existing usage.

Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.

Make iterators use GIT_ITEROVER & smart advance 1. internal iterators now return GIT_ITEROVER when you go past the last item in the iteration. 2. git_iterator_advance will "advance" to the first item in the iteration if it is called immediately after creating the iterator, which allows a simpler idiom for basic iteration. 3. if git_iterator_advance encounters an error reading data (e.g. a missing tree or an unreadable file), it returns the error but also attempts to advance past the invalid data to prevent an infinite loop. Updated all tests and internal usage of iterators to account for these new behaviors.

More diff rename tests; better split swap handling This adds a couple more tests of different rename scenarios. Also, this fixes a problem with the case where you have two "split" deltas and the left half of one matches the right half of the other. That case was already being handled, but in the wrong order in a way that could result in bad output. Also, if the swap also happened to put the other two halves into the correct place (i.e. two files exchanged places with each other), then the second delta was left with the SPLIT flag set when it really should be cleared.

Significant rename detection rewrite This flips rename detection around so instead of creating a forward mapping from deltas to possible rename targets, instead it creates a reverse mapping, looking at possible targets and trying to find a source that they could have been renamed or copied from. This is important because each output can only have a single source, but a given source could map to multiple outputs (in the form of COPIED records). Additionally, this makes a couple of tweaks to the public rename detection APIs, mostly renaming a couple of options that control the behavior to make more sense and to be more like core Git. I walked through the tests looking at the exact results and updated the expectations based on what I saw. The new code is different from the old because it cannot give some nonsense results (like A was renamed to both B and C) which were part of the outputs previously.

Fix issues with git_diff_find_similar There are a number of bugs in the rename code that only were obvious when I started testing it against large old repos with more complex patterns. (The code to do that testing is not ready to merge with libgit2, but I do plan to add more thorough tests.) This contains a significant number of changes and also tweaks the public API slightly to make emulating core git easier. Most notably, this separates the GIT_DIFF_FIND_AND_BREAK_REWRITES flag into FIND_REWRITES (which adds a self-similarity score to every modified file) and BREAK_REWRITES (which splits the modified deltas into add/remove pairs in the diff list). When you do a raw output of core git, rewrites show up as M090 or such, not at A and D output, so I wanted to be able to emulate that. Publicly, this also changes the flags to be uint16_t since we don't need values out of that range. Internally, this contains significant changes from a number of small bug fixes (like using the wrong side of the diff to decide if the object could be found in the ODB vs the workdir) to larger issues about which files can and should be compared and how the various edge cases of similarity scores should be treated. Honestly, I don't think this is the last update that will have to be made to this code, but I think this moves us closer to correct behavior and I tried to document the code so it would be easier to follow..

Add GIT_DIFF_LINE_CONTEXT_EOFNL This adds a new line origin constant for the special line that is used when both files end without a newline. In the course of writing the tests for this, I was having problems with modifying a file but not having diff notice because it was the same size and modified less than one second from the start of the test, so I decided to start working on nanosecond timestamp support. This commit doesn't contain the nanosecond support, but it contains the reorganization of maybe_modified and the hooks so that if the nanosecond data were being read by stat() (or rather being copied by git_index_entry__init_from_stat), then the nsec would be taken into account. This new stuff could probably use some more tests, although there is some amount of it here.

To make this natural, this involved a rearrangement of the code that allocates the diff object vs. the code that initializes it based on the combination of options passed in by the user and read from the config. This commit includes tests for most of these new options as well.

Tests and more fixes for submodule diffs This adds tests for diffs with submodules in them and (perhaps unsurprisingly) requires further fixes to be made. Specifically, this fixes: - when considering if a submodule is dirty in the workdir, it was being treated as dirty even if only the index was dirty. - git_diff_patch_to_str (and git_diff_patch_print) were "printing" the headers for files (and submodules) that were unmodified or had no meaningful content. - added comment to previous fix and removed unneeded parens.

Fix some diff ignores and submodule dirty workdir This started out trying to look at the problems from issue #1425 and gradually grew to a broader set of fixes. There are two core things fixed here: 1. When you had an ignore like "/bin" which is rooted at the top of your tree, instead of immediately adding the "bin/" entry as an ignored item in the diff, we were returning all of the direct descendants of the directory as ignored items. This changes things to immediately ignore the directory. Note that this effects the behavior in test_status_ignore__subdirectories so that we no longer exactly match core gits ignore behavior, but the new behavior probably makes more sense (i.e. we now will include an ignored directory inside an untracked directory that we previously would have left off). 2. When a submodule only contained working directory changes, the diff code was always considering it unmodified which was just an outright bug. The HEAD SHA of the submodule matches the SHA in the parent repo index, and since the SHAs matches, the diff code was overwriting the actual status with UNMODIFIED. These fixes broke existing tests test_diff_workdir__submodules and test_status_ignore__subdirectories but looking it over, I actually think the new results are correct and the old results were wrong. @nulltoken had actually commented on the subdirectory ignore issue previously. I also included in the tests some debugging versions of the shared iteration callback routines that print status or diff information. These aren't used actively in the tests, but can be quickly swapped in to test code to give a better picture of what is being scanned in some of the complex test scenarios.

Three submodule status bug fixes 1. Fix sort order problem with submodules where "mod" was sorting after "mod-plus" because they were being sorted as "mod/" and "mod-plus/". This involved pushing the "contains a .git entry" test significantly lower in the stack. 2. Reinstate behavior that a directory which contains a .git entry will be treated as a submodule during iteration even if it is not yet added to the .gitmodules. 3. Now that any directory containing .git is reported as submodule, we have to be more careful checking for GIT_EEXISTS when we do a submodule lookup, because that is the error code that is returned by git_submodule_lookup when you try to look up a directory containing .git that has no record in gitmodules or the index.

Add INCLUDE_TREES, DONT_AUTOEXPAND iterator flags This standardizes iterator behavior across all three iterators (index, tree, and working directory). Previously the working directory iterator behaved differently from the other two. Each iterator can now operate in one of three modes: 1. *No tree results, auto expand trees* means that only non- tree items will be returned and when a tree/directory is encountered, we will automatically descend into it. 2. *Tree results, auto expand trees* means that results will be given for every item found, including trees, but you only need to call normal git_iterator_advance to yield every item (i.e. trees returned with pre-order iteration). 3. *Tree results, no auto expand* means that calling the normal git_iterator_advance when looking at a tree will not descend into the tree, but will skip over it to the next entry in the parent. Previously, behavior 1 was the only option for index and tree iterators, and behavior 3 was the only option for workdir. The main public API implications of this are that the `git_iterator_advance_into()` call is now valid for all iterators, not just working directory iterators, and all the existing uses of working directory iterators explicitly use the GIT_ITERATOR_DONT_AUTOEXPAND (for now). Interestingly, the majority of the implementation was in the index iterator, since there are no tree entries there and now have to fake them. The tree and working directory iterators only required small modifications.

Make iterator APIs consistent with standards The iterator APIs are not currently consistent with the parameter ordering of the rest of the codebase. This rearranges the order of parameters, simplifies the naming of a number of functions, and makes somewhat better use of macros internally to clean up the iterator code. This also expands the test coverage of iterator functionality, making sure that case sensitive range-limited iteration works correctly.

Add diff rename tests with partial similarity This adds some new tests that actually exercise the similarity metric between files to detect renames, copies, and split modified files that are too heavily modified. There is still more testing to do - these tests are just partially covering the cases. There is also one bug fix in this where a change set with only MODIFY being broken into ADD/DELETE (due to low self-similarity) without any additional RENAMED entries would end up not processing the split requests (because the num_rewrites counter got reset).

Initial integration of similarity metric to diff This is the initial integration of the similarity metric into the `git_diff_find_similar()` code path. The existing tests all pass, but the new functionality isn't currently well tested. The integration does go through the pluggable metric interface, so it should be possible to drop in an alternative to the internal metric that libgit2 implements. This comes along with a behavior change for an existing interface; namely, passing two NULLs to git_diff_blobs (or passing NULLs to git_diff_blob_to_buffer) will now call the file_cb parameter zero times instead of one time. I know it's strange that that change is paired with this other change, but it emerged from some initialization changes that I ended up making.

Replace diff delta binary with flags Previously the git_diff_delta recorded if the delta was binary. This replaces that (with no net change in structure size) with a full set of flags. The flag values that were already in use for individual git_diff_file objects are reused for the delta flags, too (along with renaming those flags to make it clear that they are used more generally). This (a) makes things somewhat more consistent (because I was using a -1 value in the "boolean" binary field to indicate unset, whereas now I can just use the flags that are easier to understand), and (b) will make it easier for me to add some additional flags to the delta object in the future, such as marking the results of a copy/rename detection or other deltas that might want a special indicator. While making this change, I officially moved some of the flags that were internal only into the private diff header. This also allowed me to remove a gross hack in rename/copy detect code where I was overwriting the status field with an internal value.

diff: add a notify callback to `git_diff__from_iterators` The callback will be called for each file, just before the `git_delta_t` gets inserted into the diff list. When the callback: - returns < 0, the diff process will be aborted - returns > 0, the delta will not be inserted into the diff list, but the diff process continues - returns 0, the delta is inserted into the diff list, and the diff process continues

Add helper for diff line stats This adds a `git_diff_patch_line_stats()` API that gets the total number of adds, deletes, and context lines in a patch. This will make it a little easier to emulate `git diff --stat` and the like. Right now, this relies on generating the `git_diff_patch` object, which is a pretty heavyweight way to get stat information. At some future point, it would probably be nice to be able to get this information without allocating the entire `git_diff_patch`, but that's a much larger project.

Fix case sensitivity bug with tree iterators With the new code to make tree iterators support ignore_case, there is a bug in setting the start entry for range bounded iterators where memcmp was being used instead of strncasecmp. This fixes that and expands the tree iterator test to cover the cases that were broken.

Support case insensitive tree iterators and status This makes tree iterators directly support case insensitivity by using a secondary index that can be sorted by icase. Also, this fixes the ambiguity check in the git_status_file API to also be case insensitive. Lastly, this adds new test cases for case insensitive range boundary checking for all types of iterators. With this change, it should be possible to deprecate the spool and sort iterator, but I haven't done that yet.

Update iterator API with flags for ignore_case This changes the iterator API so that flags can be passed in to the constructor functions to control the ignore_case behavior. At this point, the flags are not supported on tree iterators (i.e. there is no functional change over the old API), but the API changes are all made to accomodate this. By the way, I went with a flags parameter because in the future I have a couple of other ideas for iterator flags that will make it easier to fix some diff/status/checkout bugs.

Fix diff patch line number calculation This was just wrong. Added a test that verifying patch line numbers even for hunks further into a file and then fixed the algorithm. I needed to add a little extra state into the patch so that I could track old and new file numbers independently, but it should be okay.

Resolve crash with diff against empty file It is not legal inside our `p_mmap` function to mmap a zero length file. This adds a test that exercises that case inside diff and fixes the code path where we would try to do that. The fix turns out not to be a lot of code since our default file content is already initialized to "" which works in this case. Fixes #1210

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

Reset all static variables to NULL in clar's __cleanup Without this change, any failed assertion in the second (or a later) test inside a test suite has a chance of double deleting memory, resulting in a heap corruption. See #1096 for details. This leaves alone the test cases where we "just" use cl_git_sandbox_init() and cl_git_sandbox_cleanup(). These methods already take good care to not double delete a repository. Fixes #1096

Improve iterator ignoring .git file The workdir iterator has always tried to ignore .git files, but it turns out there were some bugs. This makes it more robust at ignoring .git files. This also makes iterators always check ".git" case insensitively regardless of the properties of the system. This will make libgit2 skip ".GIT" and the like. This is different from core git, but on systems with case insensitive but case preserving file systems, allowing ".GIT" to be added is problematic.

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.

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.
