4ba64794	2013-08-09T10:52:35	Revert PR #1462 and provide alternative fix This rolls back the changes to fnmatch parsing from commit 2e40a60e847d6c128af23e24ea7a8efebd2427da except for the tests that were added. Instead this adds couple of new flags that can be passed in when attempting to parse an fnmatch pattern. Also, this changes the pathspec match logic to special case matching a filename with a '!' prefix against a negative pattern. This fixes the build.

7f7ebe13	2013-08-08T12:57:13	Merge pull request #1771 from nvloff/write_empty_config_value config: allow setting empty string as value
c57f6682	2013-08-08T21:17:32	config: allow empty string as value `git_config_set_string(config, "config.section", "")` fails when escaping the value. The buffer in `escape_value` is allocated without NULL-termination. And in case of empty string 0 is passed for buffer size in `git_buf_grow`. `git_buf_detach` returns NULL when the allocated size is 0 and that leads to an error return in `GITERR_CHECK_ALLOC` called after `escape_value` The change in `config_file.c` was suggested by Russell Belfer <rb@github.com>

437224b4	2013-08-05T21:46:32	More tests for ambiguous OIDs across packs The test coverage for ambiguous OIDs was pretty thin. This adds a bunch of new objects both in packs, across packs, and loose that match to 8 characters so that we can test various cases of ambiguous lookups.

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.
a5140f4d	2013-07-24T17:11:49	Fix rename detection for tree-to-tree diffs The performance improvements I introduced for rename detection were not able to run successfully for tree-to-tree diffs because the blob size was not known early enough and so the file signature always had to be calculated nonetheless. This change separates loading blobs into memory from calculating the signature. I can't avoid having to load the large blobs into memory, but by moving it forward, I'm able to avoid the signature calculation if the blob won't come into play for renames.
397357a0	2013-07-24T13:12:00	Add rename test that used to be really slow Before the optimization commits, this test used to take about 20 seconds to run on my machine. Afterwards, there is still a couple seconds of data setup, but the actual diff and rename detection runs in a fraction of a second.
197b8966	2013-07-23T14:34:31	Add hunk/file headers to git_diff_patch_size This allows git_diff_patch_size to account for hunk headers and file headers in the returned size. This required some refactoring of the code that is used to print file headers so that it could be invoked by the git_diff_patch_size API. Also this increases the test coverage and fixes an off-by-one bug in the size calculation when newline changes happen at the end of the file.
b4a4cf24	2013-07-22T16:07:56	Add git_diff_patch_size() API This adds a new API to get the size in bytes of the diffs in a git_diff_patch object.
4cee9b86	2013-07-22T11:41:23	Update init and clean for revwalk::basic tests The new tests don't always want to use the same fixture data as the old ones so this makes it configurable on a per-test basis.
b7107131	2013-07-22T11:01:19	git_reference_next_name must match git_reference_next The git_reference_next API silently skips invalid references when scanning the loose refs. The git_reference_next_name API should skip the same ones even though it isn't creating the reference object. This adds a test with a an invalid loose reference and makes sure that both APIs skip the same entries and generate the same results.

125655fe	2013-07-02T16:49:57	Untracked directories with .git should be ignored This restores a behavior that was accidentally lost during some diff refactoring where an untracked directory that contains a .git item should be treated as IGNORED, not as UNTRACKED. The submodule code already detects this, but the diff code was not handling the scenario right. This also updates a number of existing tests that were actually exercising the behavior but did not have the right expectations in place. It actually makes the new `test_diff_submodules__diff_ignore_options` test feel much better because the "not-a-submodule" entries are now ignored instead of showing up as untracked items. Fixes #1697
9564229a	2013-06-30T08:43:07	Add tests for diff.ignoreSubmdules config
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.
2e3e273e	2013-06-29T13:20:45	Update diff to new internal submodule status API Submodules now expose an internal status API that allows diff to get back the OID values from the submodule very easily and also to avoiding caching issues and to override the ignore setting for the submodule.
3fe046cf	2013-06-29T13:13:38	Add BARE option to git_repository_open_ext This adds a BARE option to git_repository_open_ext which allows a fast open path that still knows how to read gitlinks and to search for the actual .git directory from a subdirectory. `git_repository_open_bare` is still simpler and faster, but having a gitlink aware fast open is very useful for submodules where we want to quickly be able to peek at the HEAD and index data without doing any other meaningful repo operations.
e807860f	2013-06-27T16:52:38	Add timestamp check to submodule status This is probably not the final form of this change, but this is a preliminary version of checking a timestamp to see if the cached working directory HEAD OID matches the current. Right now, this uses the timestamp on the index and is, like most of our timestamp checking, subject to having only second accuracy.
4535f044	2013-06-27T16:12:44	More diff submodule tests for cache issues The submodules code caches data about submodules in a way that can cause problems. This adds some tests that try making various modifications to the state of a submodule to see where we can catch out problems in the submodule caching. Right now, I've put in an extra git_submodule_reload_all so that the test will pass, but with that commented out, the test fails. I'm working on fixing the broken version of the test at which point I'll commit the fix and delete the extra reload that makes the test pass.

12f8fe00	2013-06-27T15:43:12	More improvements to submodule diff tests This controls for the diff.mnemonicprefix setting so that can't break the tests. Also, this expands one test to emulate an ObjectiveGit test more closely.
0105b55e	2013-06-27T15:26:31	Add another submodule test of dirty wd
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.
6fc5a581	2013-07-08T22:42:02	Basic bit vector This is a simple bit vector object that is not resizable after the initial allocation but can be of arbitrary size. It will keep the bti vector entirely on the stack for vectors 64 bits or less, and will allocate the vector on the heap for larger sizes. The API is uniform regardless of storage location. This is very basic right now and all the APIs are inline functions, but it is useful for storing an array of boolean values.
d2ce27dd	2013-06-24T23:16:06	Add public API for pathspec matching This adds a new public API for compiling pathspecs and matching them against the working directory, the index, or a tree from the repository. This also reworks the pathspec internals to allow the sharing of code between the existing internal usage of pathspec matching and the new external API. While this is working and the new API is ready for discussion, I think there is still an incorrect behavior in which patterns are always matched against the full path of an entry without taking the subdirectories into account (so "s*" will match "subdir/file" even though it wouldn't with core Git). Further enhancements are coming, but this was a good place to take a functional snapshot.

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
2a16914c	2013-07-03T12:20:34	Remove GIT_STATUS_SHOW_INDEX_THEN_WORKDIR option This option serves no benefit now that the git_status_list API is available. It was of questionable value before and now it would just be a bad idea to use it rather than the indexed API.

1e9dd60f	2013-06-27T22:29:05	Test submodules with empty index or orphaned head In both of these cases, the submodule data should still be loaded just (obviously) without the data that comes from either the index or the HEAD. This fixes a bug in the orphaned head case.
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.

d4f98ba4	2013-06-21T12:29:03	Addition checkout target directory tests This adds additonal tests of the checkout target directory option including using it to dump data from bare repos.
9094ae5a	2013-06-21T11:51:16	Add target directory to checkout This adds the ability for checkout to write to a target directory instead of having to use the working directory of the repository. This makes it easier to do exports of repository data and the like. This is similar to, but not quite the same as, the --prefix option to `git checkout-index` (this will always be treated as a directory name, not just as a simple text prefix). As part of this, the workdir iterator was extended to take the path to the working directory as a parameter and fallback on the git_repository_workdir result only if it's not specified. Fixes #1332
36fd9e30	2013-06-21T11:20:54	Fix checkout of modified file when missing from wd This fixes the checkout case when a file is modified between the baseline and the target and yet missing in the working directory. The logic for that case appears to have been wrong. This also adds a useful checkout notify callback to the checkout test helpers that will count notifications and also has a debug mode to visualize what checkout thinks that it's doing.

22b6b82f	2013-06-20T12:16:06	Add status flags to force output sort order Files in status will, be default, be sorted according to the case insensitivity of the filesystem that we're running on. However, in some cases, this is not desirable. Even on case insensitive file systems, 'git status' at the command line will generally use a case sensitive sort (like 'ls'). Some GUIs prefer to display a list of file case insensitively even on case-sensitive platforms. This adds two new flags: GIT_STATUS_OPT_SORT_CASE_SENSITIVELY and GIT_STATUS_OPT_SORT_CASE_INSENSITIVELY that will override the default sort order of the status output and give the user control. This includes tests for exercising these new options and makes the examples/status.c program emulate core Git and always use a case sensitive sort.
7863523a	2013-06-19T15:54:19	Add tests and fix use of freed memory This adds some tests for updating the index and having it remove items to make sure that the iteration over the index still works even as earlier items are removed. In testing with valgrind, this found a path that would use the path string from the index entry after it had been freed. The bug fix is simply to copy the path of the index entry before doing any actual index manipulation.
f30fff45	2013-06-19T15:27:25	Add index pathspec-based operations This adds three new public APIs for manipulating the index: 1. `git_index_add_all` is similar to `git add -A` and will add files in the working directory that match a pathspec to the index while honoring ignores, etc. 2. `git_index_remove_all` removes files from the index that match a pathspec. 3. `git_index_update_all` updates entries in the index based on the current contents of the working directory, either added the new information or removing the entry from the index.
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.
a1683f28	2013-06-14T16:18:04	More tests and bug fixes for status with rename This changes the behavior of the status RENAMED flags so that they will be combined with the MODIFIED flags if appropriate. If a file is modified in the index and also renamed, then the status code will have both the GIT_STATUS_INDEX_MODIFIED and INDEX_RENAMED bits set. If it is renamed but the OID has not changed, then just the GIT_STATUS_INDEX_RENAMED bit will be set. Similarly, the flags GIT_STATUS_WT_MODIFIED and GIT_STATUS_WT_RENAMED can both be set independently of one another. This fixes a serious bug where the check for unmodified files that was done at data load time could end up erasing the RENAMED state of a file that was renamed with no changes. Lastly, this contains a bunch of new tests for status with renames, including tests where the only rename changes are case changes. The expected results of these tests have to vary by whether the platform uses a case sensitive filesystem or not, so the expected data covers those platform differences separately.

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.

Instead this adds couple of new flags that can be passed in when attempting to parse an fnmatch pattern. Also, this changes the pathspec match logic to special case matching a filename with a '!' prefix against a negative pattern. This fixes the build.

config: allow empty string as value `git_config_set_string(config, "config.section", "")` fails when escaping the value. The buffer in `escape_value` is allocated without NULL-termination. And in case of empty string 0 is passed for buffer size in `git_buf_grow`. `git_buf_detach` returns NULL when the allocated size is 0 and that leads to an error return in `GITERR_CHECK_ALLOC` called after `escape_value` The change in `config_file.c` was suggested by Russell Belfer <rb@github.com>

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.

Fix rename detection for tree-to-tree diffs The performance improvements I introduced for rename detection were not able to run successfully for tree-to-tree diffs because the blob size was not known early enough and so the file signature always had to be calculated nonetheless. This change separates loading blobs into memory from calculating the signature. I can't avoid having to load the large blobs into memory, but by moving it forward, I'm able to avoid the signature calculation if the blob won't come into play for renames.

Untracked directories with .git should be ignored This restores a behavior that was accidentally lost during some diff refactoring where an untracked directory that contains a .git item should be treated as IGNORED, not as UNTRACKED. The submodule code already detects this, but the diff code was not handling the scenario right. This also updates a number of existing tests that were actually exercising the behavior but did not have the right expectations in place. It actually makes the new `test_diff_submodules__diff_ignore_options` test feel much better because the "not-a-submodule" entries are now ignored instead of showing up as untracked items.

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.

I'm working on fixing the broken version of the test at which point I'll commit the fix and delete the extra reload that makes the test pass.

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.

Basic bit vector This is a simple bit vector object that is not resizable after the initial allocation but can be of arbitrary size. It will keep the bti vector entirely on the stack for vectors 64 bits or less, and will allocate the vector on the heap for larger sizes. The API is uniform regardless of storage location. This is very basic right now and all the APIs are inline functions, but it is useful for storing an array of boolean values.

Add public API for pathspec matching This adds a new public API for compiling pathspecs and matching them against the working directory, the index, or a tree from the repository. This also reworks the pathspec internals to allow the sharing of code between the existing internal usage of pathspec matching and the new external API. While this is working and the new API is ready for discussion, I think there is still an incorrect behavior in which patterns are always matched against the full path of an entry without taking the subdirectories into account (so "s*" will match "subdir/file" even though it wouldn't with core Git). Further enhancements are coming, but this was a good place to take a functional snapshot.

Add status flags to force output sort order Files in status will, be default, be sorted according to the case insensitivity of the filesystem that we're running on. However, in some cases, this is not desirable. Even on case insensitive file systems, 'git status' at the command line will generally use a case sensitive sort (like 'ls'). Some GUIs prefer to display a list of file case insensitively even on case-sensitive platforms. This adds two new flags: GIT_STATUS_OPT_SORT_CASE_SENSITIVELY and GIT_STATUS_OPT_SORT_CASE_INSENSITIVELY that will override the default sort order of the status output and give the user control. This includes tests for exercising these new options and makes the examples/status.c program emulate core Git and always use a case sensitive sort.

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.

More tests and bug fixes for status with rename This changes the behavior of the status RENAMED flags so that they will be combined with the MODIFIED flags if appropriate. If a file is modified in the index and also renamed, then the status code will have both the GIT_STATUS_INDEX_MODIFIED and INDEX_RENAMED bits set. If it is renamed but the OID has not changed, then just the GIT_STATUS_INDEX_RENAMED bit will be set. Similarly, the flags GIT_STATUS_WT_MODIFIED and GIT_STATUS_WT_RENAMED can both be set independently of one another. This fixes a serious bug where the check for unmodified files that was done at data load time could end up erasing the RENAMED state of a file that was renamed with no changes. Lastly, this contains a bunch of new tests for status with renames, including tests where the only rename changes are case changes. The expected results of these tests have to vary by whether the platform uses a case sensitive filesystem or not, so the expected data covers those platform differences separately.

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.

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.

signature: extend trimming to more whitespace There are all sorts of misconfiguration in the wild. We already rely on the signature constructor to trim SP. Extend the logic to use `isspace` to decide whether a character should be trimmed.

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.
