7e3faf58	2017-10-29T15:05:28	diff: expose the "indent heuristic" in the diff options We default to off, but we might want to consider changing `GIT_DIFF_NORMAL` to include it.
f063dafb	2017-11-12T10:56:50	signature: distinguish +0000 and -0000 UTC offsets Git considers '-0000' a valid offset for signature lines. They need to be treated as _not_ equal to a '+0000' signature offset. Parsing a signature line stores the offset in a signed integer which does not distinguish between `+0` and `-0`. This patch adds an additional flag `sign` to the `git_time` in the `signature` object which is populated with the sign of the offset. In addition to exposing this information to the user, this information is also used to compare signatures. /cc @pks-t @ethomson

529e873c	2017-05-23T11:51:00	config: pass repository when opening config files Our current configuration logic is completely oblivious of any repository, but only cares for actual file paths. Unfortunately, we are forced to break this assumption by the introduction of conditional includes, which are evaluated in the context of a repository. Right now, only one conditional exists with "gitdir:" -- it will only include the configuration if the current repository's git directory matches the value passed to "gitdir:". To support these conditionals, we have to break our API and make the repository available when opening a configuration file. This commit extends the `open` call of configuration backends to include another repository and adjusts existing code to have it available. This includes the user-visible functions `git_config_add_file_ondisk` and `git_config_add_backend`.

9093ced6	2017-07-10T11:42:26	patch_generate: represent buffers as void pointers Pointers to general data should usually be used as a void pointer such that it is possible to hand in variables of a different pointer type without the need to cast. This is the same when creating patches from buffers, where the buffers may contain arbitrary data. Instead of requiring the caller to care whether his buffer is e.g. `char ` or `unsigned char `, we should instead just accept a `void *`. This is also consistent in how we tread other types like for example `git_blob`, which also just has a void pointer as its raw contents.

89a34828	2017-06-16T13:34:43	diff: implement function to calculate patch ID The upstream git project provides the ability to calculate a so-called patch ID. Quoting from git-patch-id(1): A "patch ID" is nothing but a sum of SHA-1 of the file diffs associated with a patch, with whitespace and line numbers ignored." Patch IDs can be used to identify two patches which are probably the same thing, e.g. when a patch has been cherry-picked to another branch. This commit implements a new function `git_diff_patchid`, which gets a patch and derives an OID from the diff. Note the different terminology here: a patch in libgit2 are the differences in a single file and a diff can contain multiple patches for different files. The implementation matches the upstream implementation and should derive the same OID for the same diff. In fact, some code has been directly derived from the upstream implementation. The upstream implementation has two different modes to calculate patch IDs, which is the stable and unstable mode. The old way of calculating the patch IDs was unstable in a sense that a different ordering the diffs was leading to different results. This oversight was fixed in git 1.9, but as git tries hard to never break existing workflows, the old and unstable way is still default. The newer and stable way does not care for ordering of the diff hunks, and in fact it is the mode that should probably be used today. So right now, we only implement the stable way of generating the patch ID.

6c23704d	2017-06-08T21:40:18	settings: rename `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION` Initially, the setting has been solely used to enable the use of `fsync()` when creating objects. Since then, the use has been extended to also cover references and index files. As the option is not yet part of any release, we can still correct this by renaming the option to something more sensible, indicating not only correlation to objects. This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also move the variable from the object to repository source code.

883eeb5f	2017-05-02T12:35:59	worktree: switch over worktree pruning to an opts structure The current signature of `git_worktree_prune` accepts a flags field to alter its behavior. This is not as flexible as we'd like it to be when we want to enable passing additional options in the future. As the function has not been part of any release yet, we are still free to alter its current signature. This commit does so by using our usual pattern of an options structure, which is easily extendable without breaking the API.
8264a30f	2017-05-02T10:11:28	worktree: support creating locked worktrees When creating a new worktree, we do have a potential race with us creating the worktree and another process trying to delete the same worktree as it is being created. As such, the upstream git project has introduced a flag `git worktree add --locked`, which will cause the newly created worktree to be locked immediately after its creation. This mitigates the race condition. We want to be able to mirror the same behavior. As such, a new flag `locked` is added to the options structure of `git_worktree_add` which allows the user to enable this behavior.
4bc16c37	2016-07-08T01:37:22	remote: add function to create detached remotes Right now it is only possible to create remotes from a repository. While this is probably the most common use-case, there are commands which make sense even without a repository, e.g. the equivalence of `git ls-remote`. Add a new function `git_remote_create_detached`, which simply accepts a URL.
a7aa73a5	2017-05-02T10:02:36	worktree: introduce git_worktree_add options The `git_worktree_add` function currently accepts only a path and name for the new work tree. As we may want to expand these parameters in future versions without adding additional parameters to the function for every option, this commit introduces our typical pattern of an options struct. Right now, this structure is still empty, which will change with the next commit.

35079f50	2017-04-21T07:31:56	odb: add option to turn off hash verification Verifying hashsums of objects we are reading from the ODB may be costly as we have to perform an additional hashsum calculation on the object. Especially when reading large objects, the penalty can be as high as 35%, as can be seen when executing the equivalent of `git cat-file` with and without verification enabled. To mitigate for this, we add a global option for libgit2 which enables the developer to turn off the verification, e.g. when he can be reasonably sure that the objects on disk won't be corrupted.
28a0741f	2017-04-10T09:30:08	odb: verify object hashes The upstream git.git project verifies objects when looking them up from disk. This avoids scenarios where objects have somehow become corrupt on disk, e.g. due to hardware failures or bit flips. While our mantra is usually to follow upstream behavior, we do not do so in this case, as we never check hashes of objects we have just read from disk. To fix this, we create a new error class `GIT_EMISMATCH` which denotes that we have looked up an object with a hashsum mismatch. `odb_read_1` will then, after having read the object from its backend, hash the object and compare the resulting hash to the expected hash. If hashes do not match, it will return an error. This obviously introduces another computation of checksums and could potentially impact performance. Note though that we usually perform I/O operations directly before doing this computation, and as such the actual overhead should be drowned out by I/O. Running our test suite seems to confirm this guess. On a Linux system with best-of-five timings, we had 21.592s with the check enabled and 21.590s with the ckeck disabled. Note though that our test suite mostly contains very small blobs only. It is expected that repositories with bigger blobs may notice an increased hit by this check. In addition to a new test, we also had to change the odb::backend::nonrefreshing test suite, which now triggers a hashsum mismatch when looking up the commit "deadbeef...". This is expected, as the fake backend allocated inside of the test will return an empty object for the OID "deadbeef...", which will obviously not hash back to "deadbeef..." again. We can simply adjust the hash to equal the hash of the empty object here to fix this test.

While these functions called `git_buf_sanitize` on these buffers, this is not the right thing to do, as it will simply initialize or zero-terminate passed buffers. As we want to overwrite contents, we instead have to call `git_buf_clear` to completely reset them.

Added a `git_repository_submodule_cache_clear` function to remove the cache. Also optimized the function that loads all submodules as it was itself O(N^2) w.r.t the number of submodules, having to loop through the `.gitmodules` file once per submodule.

Parsing a signature line stores the offset in a signed integer which does not distinguish between `+0` and `-0`. This patch adds an additional flag `sign` to the `git_time` in the `signature` object which is populated with the sign of the offset. In addition to exposing this information to the user, this information is also used to compare signatures. /cc @pks-t @ethomson

config: pass repository when opening config files Our current configuration logic is completely oblivious of any repository, but only cares for actual file paths. Unfortunately, we are forced to break this assumption by the introduction of conditional includes, which are evaluated in the context of a repository. Right now, only one conditional exists with "gitdir:" -- it will only include the configuration if the current repository's git directory matches the value passed to "gitdir:". To support these conditionals, we have to break our API and make the repository available when opening a configuration file. This commit extends the `open` call of configuration backends to include another repository and adjusts existing code to have it available. This includes the user-visible functions `git_config_add_file_ondisk` and `git_config_add_backend`.

patch_generate: represent buffers as void pointers Pointers to general data should usually be used as a void pointer such that it is possible to hand in variables of a different pointer type without the need to cast. This is the same when creating patches from buffers, where the buffers may contain arbitrary data. Instead of requiring the caller to care whether his buffer is e.g. `char *` or `unsigned char *`, we should instead just accept a `void *`. This is also consistent in how we tread other types like for example `git_blob`, which also just has a void pointer as its raw contents.

diff: implement function to calculate patch ID The upstream git project provides the ability to calculate a so-called patch ID. Quoting from git-patch-id(1): A "patch ID" is nothing but a sum of SHA-1 of the file diffs associated with a patch, with whitespace and line numbers ignored." Patch IDs can be used to identify two patches which are probably the same thing, e.g. when a patch has been cherry-picked to another branch. This commit implements a new function `git_diff_patchid`, which gets a patch and derives an OID from the diff. Note the different terminology here: a patch in libgit2 are the differences in a single file and a diff can contain multiple patches for different files. The implementation matches the upstream implementation and should derive the same OID for the same diff. In fact, some code has been directly derived from the upstream implementation. The upstream implementation has two different modes to calculate patch IDs, which is the stable and unstable mode. The old way of calculating the patch IDs was unstable in a sense that a different ordering the diffs was leading to different results. This oversight was fixed in git 1.9, but as git tries hard to never break existing workflows, the old and unstable way is still default. The newer and stable way does not care for ordering of the diff hunks, and in fact it is the mode that should probably be used today. So right now, we only implement the stable way of generating the patch ID.

settings: rename `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION` Initially, the setting has been solely used to enable the use of `fsync()` when creating objects. Since then, the use has been extended to also cover references and index files. As the option is not yet part of any release, we can still correct this by renaming the option to something more sensible, indicating not only correlation to objects. This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also move the variable from the object to repository source code.

worktree: switch over worktree pruning to an opts structure The current signature of `git_worktree_prune` accepts a flags field to alter its behavior. This is not as flexible as we'd like it to be when we want to enable passing additional options in the future. As the function has not been part of any release yet, we are still free to alter its current signature. This commit does so by using our usual pattern of an options structure, which is easily extendable without breaking the API.

worktree: support creating locked worktrees When creating a new worktree, we do have a potential race with us creating the worktree and another process trying to delete the same worktree as it is being created. As such, the upstream git project has introduced a flag `git worktree add --locked`, which will cause the newly created worktree to be locked immediately after its creation. This mitigates the race condition. We want to be able to mirror the same behavior. As such, a new flag `locked` is added to the options structure of `git_worktree_add` which allows the user to enable this behavior.

Right now, this structure is still empty, which will change with the next commit.

odb: add option to turn off hash verification Verifying hashsums of objects we are reading from the ODB may be costly as we have to perform an additional hashsum calculation on the object. Especially when reading large objects, the penalty can be as high as 35%, as can be seen when executing the equivalent of `git cat-file` with and without verification enabled. To mitigate for this, we add a global option for libgit2 which enables the developer to turn off the verification, e.g. when he can be reasonably sure that the objects on disk won't be corrupted.

odb: verify object hashes The upstream git.git project verifies objects when looking them up from disk. This avoids scenarios where objects have somehow become corrupt on disk, e.g. due to hardware failures or bit flips. While our mantra is usually to follow upstream behavior, we do not do so in this case, as we never check hashes of objects we have just read from disk. To fix this, we create a new error class `GIT_EMISMATCH` which denotes that we have looked up an object with a hashsum mismatch. `odb_read_1` will then, after having read the object from its backend, hash the object and compare the resulting hash to the expected hash. If hashes do not match, it will return an error. This obviously introduces another computation of checksums and could potentially impact performance. Note though that we usually perform I/O operations directly before doing this computation, and as such the actual overhead should be drowned out by I/O. Running our test suite seems to confirm this guess. On a Linux system with best-of-five timings, we had 21.592s with the check enabled and 21.590s with the ckeck disabled. Note though that our test suite mostly contains very small blobs only. It is expected that repositories with bigger blobs may notice an increased hit by this check. In addition to a new test, we also had to change the odb::backend::nonrefreshing test suite, which now triggers a hashsum mismatch when looking up the commit "deadbeef...". This is expected, as the fake backend allocated inside of the test will return an empty object for the OID "deadbeef...", which will obviously not hash back to "deadbeef..." again. We can simply adjust the hash to equal the hash of the empty object here to fix this test.

While these functions called `git_buf_sanitize` on these buffers, this is not the right thing to do, as it will simply initialize or zero-terminate passed buffers. As we want to overwrite contents, we instead have to call `git_buf_clear` to completely reset them.
