This is however something we force when truncating racily-clean entries. Tick the index forward as we know that we don't perform the modifications which the racily-clean code is trying to avoid.
77596fcf	2015-06-15T09:51:34	diff: add failing test for racy-git in the index We update the index and then immediately change the contents of the file. This makes the diff think there are no changes, as the timestamp of the file agrees with the cached data. This is however a bug, as the file has obviously changed contents. The test is a bit fragile, as it assumes that the index writing and the following modification of the file happen in the same second, but it's enough to show the issue.

659cf202	2015-01-07T12:23:05	Remove the signature from ref-modifying functions The signature for the reflog is not something which changes dynamically. Almost all uses will be NULL, since we want for the repository's default identity to be used, making it noise. In order to allow for changing the identity, we instead provide git_repository_set_ident() and git_repository_ident() which allow a user to override the choice of signature.
36fc5497	2014-12-02T05:11:12	Added GIT_HASHSIG_ALLOW_SMALL_FILES to allow computing signatures for small files The implementation of the hashsig API disallows computing a signature on small files containing only a few lines. This new flag disables this behavior. git_diff_find_similar() sets this flag by default which means that rename / copy detection of small files will now work. This in turn affects the behavior of the git_status and git_blame APIs which will now detect rename of small files assuming the right options are passed.

We need the index or tree we are comparing against to tell us. Otherwise we have to assume the entry in .gitmodules is stale or otherwise invalid. Thus we pass the index of the repository into the workdir iterator, even if we do not want to compare against it. This follows what git does, which even for `git diff <tree>`, it will consider staged submodules as such.

f554611a	2014-05-06T12:41:26	Improve checks for ignore containment The diff code was using an "ignored_prefix" directory to track if a parent directory was ignored that contained untracked files alongside tracked files. Unfortunately, when negative ignore rules were used for directories inside ignored parents, the wrong rules were applied to untracked files inside the negatively ignored child directories. This commit moves the logic for ignore containment into the workdir iterator (which is a better place for it), so the ignored-ness of a directory is contained in the frame stack during traversal. This allows a child directory to override with a negative ignore and yet still restore the ignored state of the parent when we traverse out of the child. Along with this, there are some problems with "directory only" ignore rules on container directories. Given "a/*" and "!a/b/c/" (where the second rule is a directory rule but the first rule is just a generic prefix rule), then the directory only constraint was having "a/b/c/d/file" match the first rule and not the second. This was fixed by having ignore directory-only rules test a rule against the prefix of a file with LEADINGDIR enabled. Lastly, spot checks for ignores using `git_ignore_path_is_ignored` were tested from the top directory down to the bottom to deal with the containment problem, but this is wrong. We have to test bottom to top so that negative subdirectory rules will be checked before parent ignore rules. This does change the behavior of some existing tests, but it seems only to bring us more in line with core Git, so I think those changes are acceptable.

This can result in files that show as modified with no actual diff, but the behavior actually appears to match Git on the command line. This also includes a minor optimization to not perform a submodule lookup on the ".git" directory itself.

e349ed50	2014-04-22T14:58:33	patch: emit binary patches (optionally)
8d09efa2	2014-04-22T12:33:27	Use git_diff_get_stats in example/diff + refactor This takes the `--stat` and related example options in the example diff.c program and converts them to use the `git_diff_get_stats` API which nicely formats stats for you. I went to add bar-graph scaling to the stats formatter and noticed that the `git_diff_stats` structure was holding on to all of the `git_patch` objects. Unfortunately, each of these objects keeps the full text of the diff in memory, so this is very expensive. I ended up modifying `git_diff_stats` to keep just the data that it needs to keep and allowed it to release the patches. Then, I added width scaling to the output on top of that. In making the diff example program match 'git diff' output, I ended up removing an newline from the sumamry output which I then had to compensate for in the email formatting to match the expectations. Lastly, I went through and refactored the tests to use a couple of helper functions and reduce the overall amount of code there.
8a2834d3	2014-03-14T13:20:51	Index locking and entry allocation changes This makes the lock management on the index a little bit broader, having a number of routines hold the lock across looking up the item to be modified and actually making the modification. Still not true thread safety, but more pure index modifications are now safe which allows the simple cases (such as starting up a diff while index modifications are underway) safe enough to get the snapshot without hitting allocation problems. As part of this, I simplified the allocation of index entries to use a flex array and just put the path at the end of the index entry. This makes every entry self-contained and makes it a little easier to feel sure that pointers to strings aren't being accidentally copied and freed while other references are still being held.
3b4c401a	2014-02-10T13:20:08	Decouple index iterator sort from index This makes the index iterator honor the GIT_ITERATOR_IGNORE_CASE and GIT_ITERATOR_DONT_IGNORE_CASE flags without modifying the index data itself. To take advantage of this, I had to export a number of the internal index entry comparison functions. I also wrote some new tests to exercise the capability.
27e54bcf	2014-02-07T14:17:19	Add public diff print helpers The usefulness of these helpers came up for me while debugging some of the iterator changes that I was making, so since they have also been requested (albeit indirectly) I thought I'd include them.

8061d519	2014-04-01T13:24:06	Remove most submodule reloads from tests With the new submodule cache validity checks, we generally don't need to call git_submodule_reload_all to have up-to-date submodule data. Some tests are still calling it where I want to actually test that it can be called safely and doesn't break anything, but mostly it is not needed. This also expands some of the existing submodule tests to cover some variants on the behavior that was already being tested.

dc7efa1a	2014-03-26T18:29:34	Merge pull request #2204 from libgit2/rb/submodule-reference-counting Make submodules externally refcounted
d3bc95fd	2014-03-25T12:37:05	Update behavior for untracked sub-repos When a directory containing a .git directory (or even just a plain gitlink) was found, libgit2 was going out of its way to treat it specially. This seemed like it was necessary because the diff code was not originally emulating Git's behavior for untracked directories correctly (i.e. scanning for ignored vs untracked items inside). Now that libgit2 diff mimics Git's untracked directory behavior, the special handling for contained Git repos is actually incorrect and this commit rips it out.
a15c7802	2014-03-25T09:14:48	Make submodules externally refcounted `git_submodule` objects were already refcounted internally in case the submodule name was different from the path at which it was stored. This makes that refcounting externally used as well, so `git_submodule_lookup` and `git_submodule_add_setup` return an object that requires a `git_submodule_free` when done.

This also includes a bunch of internal refactoring to increase the shared code between these functions and the blob-to-blob and blob-to-buffer APIs, as well as some higher level assert helpers in the tests to also remove redundancy.

082e82db	2014-01-27T11:45:06	Update Javascript userdiff driver and tests Writing a sample Javascript driver pointed out some extra whitespace handling that needed to be done in the diff driver. This adds some tests with some sample javascript code that I pulled off of GitHub just to see what would happen. Also, to clean up the userdiff test data, I did a "git gc" and packed up the test objects.

2c65602e	2014-01-21T10:39:27	Import git drivers and test HTML driver Reorganize the builtin driver table slightly so that core Git builtin definitions can be imported verbatim. Then take a few of the core Git drivers and pull them in. This also creates a test of diffs with the builtin HTML driver which led to some small error handling fixes in the driver selection logic.
c05cd792	2014-01-22T17:51:32	Drop git_patch_to_str It's hard or even impossible to correctly free the string buffer allocated by git_patch_to_str in some circumstances. Drop the function so people have to use git_patch_to_buf instead - git_buf has a dedicated destructor.
0b28217b	2014-01-15T12:51:31	refs: remove the _with_log differentiation Any well-behaved program should write a descriptive message to the reflog whenever it updates a reference. Let's make this more prominent by removing the version without the reflog parameters.
11bd7a03	2013-12-12T11:14:51	More tests of canceling from callbacks This covers diff print, push, and ref foreach. This also has a fix for a small memory leak in the push tests.
8b22d862	2013-12-11T11:55:00	More improvements to callback return value tests This time actually checking return values in diff notify tests and actually testing callbacks for the index all-all/update-all/etc functions.
25e0b157	2013-12-06T15:07:57	Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.

97ad85b8	2013-12-02T13:30:05	Add GIT_DIFF_FIND_DELETE_UNMODIFIED flag When doing copy detection, it is often necessary to include UNMODIFIED records in the git_diff so they are available as source records for GIT_DIFF_FIND_COPIES_FROM_UNMODIFIED. Yet in the final diff, often you will not want to have these UNMODIFIED records. This adds a flag which marks these UNMODIFIED records for deletion from the diff list so they will be removed after the rename detect phase is over.
2123a17f	2013-12-02T13:27:06	Fix bug making split deltas a COPIED targets When FIND_COPIES is used in combination with BREAK_REWRITES for rename detection, there was a bug where the split MODIFIED delta was only used as a target for RENAME records and not for COPIED records. This fixes that, converting the split into a pair of DELETED and COPIED deltas when that circumstance arises.

This can result in files that show as modified with no actual diff, but the behavior actually appears to match Git on the command line. This also includes a minor optimization to not perform a submodule lookup on the ".git" directory itself.

Use git_diff_get_stats in example/diff + refactor This takes the `--stat` and related example options in the example diff.c program and converts them to use the `git_diff_get_stats` API which nicely formats stats for you. I went to add bar-graph scaling to the stats formatter and noticed that the `git_diff_stats` structure was holding on to all of the `git_patch` objects. Unfortunately, each of these objects keeps the full text of the diff in memory, so this is very expensive. I ended up modifying `git_diff_stats` to keep just the data that it needs to keep and allowed it to release the patches. Then, I added width scaling to the output on top of that. In making the diff example program match 'git diff' output, I ended up removing an newline from the sumamry output which I then had to compensate for in the email formatting to match the expectations. Lastly, I went through and refactored the tests to use a couple of helper functions and reduce the overall amount of code there.

Index locking and entry allocation changes This makes the lock management on the index a little bit broader, having a number of routines hold the lock across looking up the item to be modified and actually making the modification. Still not true thread safety, but more pure index modifications are now safe which allows the simple cases (such as starting up a diff while index modifications are underway) safe enough to get the snapshot without hitting allocation problems. As part of this, I simplified the allocation of index entries to use a flex array and just put the path at the end of the index entry. This makes every entry self-contained and makes it a little easier to feel sure that pointers to strings aren't being accidentally copied and freed while other references are still being held.

Decouple index iterator sort from index This makes the index iterator honor the GIT_ITERATOR_IGNORE_CASE and GIT_ITERATOR_DONT_IGNORE_CASE flags without modifying the index data itself. To take advantage of this, I had to export a number of the internal index entry comparison functions. I also wrote some new tests to exercise the capability.

Remove most submodule reloads from tests With the new submodule cache validity checks, we generally don't need to call git_submodule_reload_all to have up-to-date submodule data. Some tests are still calling it where I want to actually test that it can be called safely and doesn't break anything, but mostly it is not needed. This also expands some of the existing submodule tests to cover some variants on the behavior that was already being tested.

Merge pull request #2204 from libgit2/rb/submodule-reference-counting Make submodules externally refcounted

2014-03-25T12:37:05

Update behavior for untracked sub-repos When a directory containing a .git directory (or even just a plain gitlink) was found, libgit2 was going out of its way to treat it specially. This seemed like it was necessary because the diff code was not originally emulating Git's behavior for untracked directories correctly (i.e. scanning for ignored vs untracked items inside). Now that libgit2 diff mimics Git's untracked directory behavior, the special handling for contained Git repos is actually incorrect and this commit rips it out.

Make submodules externally refcounted `git_submodule` objects were already refcounted internally in case the submodule name was different from the path at which it was stored. This makes that refcounting externally used as well, so `git_submodule_lookup` and `git_submodule_add_setup` return an object that requires a `git_submodule_free` when done.

Also, to clean up the userdiff test data, I did a "git gc" and packed up the test objects.

Import git drivers and test HTML driver Reorganize the builtin driver table slightly so that core Git builtin definitions can be imported verbatim. Then take a few of the core Git drivers and pull them in. This also creates a test of diffs with the builtin HTML driver which led to some small error handling fixes in the driver selection logic.

Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.

Add GIT_DIFF_FIND_DELETE_UNMODIFIED flag When doing copy detection, it is often necessary to include UNMODIFIED records in the git_diff so they are available as source records for GIT_DIFF_FIND_COPIES_FROM_UNMODIFIED. Yet in the final diff, often you will not want to have these UNMODIFIED records. This adds a flag which marks these UNMODIFIED records for deletion from the diff list so they will be removed after the rename detect phase is over.
