b859faa6	2016-08-23T23:38:39	Teach `git_patch_from_diff` about parsed diffs Ensure that `git_patch_from_diff` can return the patch for parsed diffs, not just generate a patch for a generated diff.
1a79cd95	2016-04-26T01:18:01	patch: show copy information for identical copies When showing copy information because we are duplicating contents, for example, when performing a `diff --find-copies-harder -M100 -B100`, then show copy from/to lines in a patch, and do not show context. Ensure that we can also parse such patches.

de034cd2	2016-03-18T10:59:38	iterator: give the tests a proper hierarchy Iterator tests were split over repo::iterator and diff::iterator, with duplication between the two. Move them to iterator::index, iterator::tree, and iterator::workdir.
df25daef	2016-01-04T12:12:24	Added clar test for #3568
be30387e	2016-02-25T16:05:18	iterators: refactored tree iterator Refactored the tree iterator to never recurse; simply process the next entry in order in `advance`. Additionally, reduce the number of allocations and sorting as much as possible to provide a ~30% speedup on case-sensitive iteration. (The gains for case-insensitive iteration are less majestic.)
684b35c4	2016-02-25T15:11:14	iterator: disambiguate reset and reset_range Disambiguate the reset and reset_range functions. Now reset_range with a NULL path will clear the start or end; reset will leave the existing start and end unchanged.
60a194aa	2016-03-20T11:00:12	tree: re-use the id and filename in the odb object Instead of copying over the data into the individual entries, point to the originals, which are already in a format we can use.

f20480ab	2015-11-03T09:40:30	diff: test "symlinks" in wd are respected on win32 When `core.symlinks = false`, we write the symlinks content (target) to a regular file. We should ensure that when we later see that regular file, we treat it specially - and that changing that regular file would actually change the symlink target. (For compatibility with Git for Windows).

d53c8880	2015-08-30T19:25:47	iterator: saner pathlist matching for idx iterator Some nicer refactoring for index iteration walks. The index iterator doesn't binary search through the pathlist space, since it lacks directory entries, and would have to binary search each index entry and all its parents (eg, when presented with an index entry of `foo/bar/file.c`, you would have to look in the pathlist for `foo/bar/file.c`, `foo/bar` and `foo`). Since the index entries and the pathlist are both nicely sorted, we walk the index entries in lockstep with the pathlist like we do for other iteration/diff/merge walks.
4a0dbeb0	2015-08-30T17:06:26	diff: use new iterator pathlist handling When using literal pathspecs in diff with `GIT_DIFF_DISABLE_PATHSPEC_MATCH` turn on the faster iterator pathlist handling. Updates iterator pathspecs to include directory prefixes (eg, `foo/`) for compatibility with `GIT_DIFF_DISABLE_PATHSPEC_MATCH`.
3273ab3f	2015-08-28T20:06:18	diff: better document GIT_DIFF_PATHSPEC_DISABLE Document that `GIT_DIFF_PATHSPEC_DISABLE` is not necessarily about explicit path matching, but also includes matching of directory names. Enforce this in a test.

e451cd5c	2015-08-15T18:46:38	diff: don't error out on an invalid regex When parsing user-provided regex patterns for functions, we must not fail to provide a diff just because a pattern is not well formed. Ignore it instead.

8d8a2eef	2015-06-15T11:14:40	Fixed GIT_DELTA_CONFLICTED not returned in some cases If an index entry for a file that is not in HEAD is in conflicted state, when diffing HEAD with the index, the status field of the corresponding git_diff_delta was incorrectly reported as GIT_DELTA_ADDED instead of GIT_DELTA_CONFLICTED. This was due to handle_unmatched_new_item() initially setting the status to GIT_DELTA_CONFLICTED but then overriding it later with GIT_DELTA_ADDED.
cb63e7e8	2015-06-17T08:55:09	Explicitly handle GIT_DELTA_CONFLICTED in git_diff_merge() This fixes a bug where if a file was in conflicted state in either diff, it would not always remain in conflicted state in the merged diff.
c6f489c9	2015-05-04T17:29:12	submodule: add an ignore option to status This lets us specify in the status call which ignore rules we want to use (optionally falling back to whatever the submodule has in its configuration). This removes one of the reasons for having `_set_ignore()` set the value in-memory. We re-use the `IGNORE_RESET` value for this as it is no longer relevant but has a similar purpose to `IGNORE_FALLBACK`. Similarly, we remove `IGNORE_DEFAULT` which does not have use outside of initializers and move that to fall back to the configuration as well.
5a9fc6c8	2015-05-04T16:22:56	submodule: make set_ignore() affect the configuration Instead of affecting a particular instance, make it change the configuration.

ff475375	2015-06-17T14:34:10	diff: check files with the same or newer timestamps When a file on the workdir has the same or a newer timestamp than the index, we need to perform a full check of the contents, as the update of the file may have happened just after we wrote the index. The iterator changes are such that we can reach inside the workdir iterator from the diff, though it may be better to have an accessor instead of moving these structs into the header.
a56db992	2015-06-17T08:15:49	Merge pull request #3219 from libgit2/cmn/racy-diff Zero out racily-clean entries' file_size
e44abe16	2015-06-16T08:51:45	tests: tick the index when we count OID calculations These tests want to test that we don't recalculate entries which match the index already. 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.
f7fcb18f	2014-11-23T14:12:54	Plug leaks Valgrind is now clean except for libssl and libgcrypt.
62a617dc	2014-11-06T16:16:46	iterator: submodules are determined by an index or tree We cannot know from looking at .gitmodules whether a directory is a submodule or not. 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.

ce3b71d9	2014-05-12T10:28:45	Don't scale diff stat when not needed
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.

7a2e56a3	2014-04-29T14:30:15	Get rid of redundant git_diff_options_init fn Since git_diff_init_options was introduced, remove this old fn.
b23b112d	2014-04-29T11:29:49	Add payloads, bitmaps to trace API This is a proposed adjustment to the trace APIs. This makes the trace levels into a bitmask so that they can be selectively enabled and adds a callback-level payload, plus a message-level payload. This makes it easier for me to a GIT_TRACE_PERF callbacks that are simply bypassed if the PERF level is not set.
225aab5d	2014-04-28T16:47:39	Don't use trace if GIT_TRACE not defined
cd424ad5	2014-04-28T16:39:53	Add GIT_STATUS_OPT_UPDATE_INDEX and use trace API This adds an option to refresh the stat cache while generating status. It also rips out the GIT_PERF stuff I had an makes use of the trace API to keep statistics about what happens during diff.
94fb4aad	2014-04-28T14:48:41	Add diff option to update index stat cache When diff is scanning the working directory, if it finds a file where it is not sure if the index entry matches the working dir, it will recalculate the OID (which is pretty expensive). This adds a new flag to diff so that if the OID calculation finds that the file actually has not changed (i.e. just the modified time was altered or such), then it will refresh the stat cache in the index so that future calls to diff will not have to check the oid again.
8ef4e11a	2014-04-28T14:16:26	Skip diff oid calc when size definitely changed When we think the stat cache in the index seems valid and the size or mode of a file has definitely changed, then don't bother trying to recalculate the OID of the workdir bits to confirm that it is modified - just accept that it is modified. 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.
240f4af3	2014-04-28T14:04:29	Add build option for diff internal statistics

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.

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.

iterator: saner pathlist matching for idx iterator Some nicer refactoring for index iteration walks. The index iterator doesn't binary search through the pathlist space, since it lacks directory entries, and would have to binary search each index entry and all its parents (eg, when presented with an index entry of `foo/bar/file.c`, you would have to look in the pathlist for `foo/bar/file.c`, `foo/bar` and `foo`). Since the index entries and the pathlist are both nicely sorted, we walk the index entries in lockstep with the pathlist like we do for other iteration/diff/merge walks.

This was due to handle_unmatched_new_item() initially setting the status to GIT_DELTA_CONFLICTED but then overriding it later with GIT_DELTA_ADDED.

submodule: add an ignore option to status This lets us specify in the status call which ignore rules we want to use (optionally falling back to whatever the submodule has in its configuration). This removes one of the reasons for having `_set_ignore()` set the value in-memory. We re-use the `IGNORE_RESET` value for this as it is no longer relevant but has a similar purpose to `IGNORE_FALLBACK`. Similarly, we remove `IGNORE_DEFAULT` which does not have use outside of initializers and move that to fall back to the configuration as well.

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.

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.

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.

iterator: submodules are determined by an index or tree We cannot know from looking at .gitmodules whether a directory is a submodule or not. 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.

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.

Add diff option to update index stat cache When diff is scanning the working directory, if it finds a file where it is not sure if the index entry matches the working dir, it will recalculate the OID (which is pretty expensive). This adds a new flag to diff so that if the OID calculation finds that the file actually has not changed (i.e. just the modified time was altered or such), then it will refresh the stat cache in the index so that future calls to diff will not have to check the oid again.

8ef4e11a

2014-04-28T14:16:26

Skip diff oid calc when size definitely changed When we think the stat cache in the index seems valid and the size or mode of a file has definitely changed, then don't bother trying to recalculate the OID of the workdir bits to confirm that it is modified - just accept that it is modified. 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.

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.
