Patrick Steinhardt 4296a36b 2017-07-10T09:36:19 ignore: honor case insensitivity for negative ignores When computing negative ignores, we throw away any rule which does not undo a previous rule to optimize. But on case insensitive file systems, we need to keep in mind that a negative ignore can also undo a previous rule with different case, which we did not yet honor while determining whether a rule undoes a previous one. So in the following example, we fail to unignore the "/Case" directory: /case !/Case Make both paths checking whether a plain- or wildcard-based rule undo a previous rule aware of case-insensitivity. This fixes the described issue.

lhchavez 5cc3971a 2017-12-06T03:22:58 libFuzzer: Fix a git_packfile_stream leak This change ensures that the git_packfile_stream object in git_indexer_append() does not leak when the stream has errors. Found using libFuzzer.
Patrick Steinhardt 5c15cd94 2017-07-07T13:27:27 ignore: keep negative rules containing wildcards Ignore rules allow for reverting a previously ignored rule by prefixing it with an exclamation mark. As such, a negative rule can only override previously ignored files. While computing all ignore patterns, we try to use this fact to optimize away some negative rules which do not override any previous patterns, as they won't change the outcome anyway. In some cases, though, this optimization causes us to get the actual ignores wrong for some files. This may happen whenever the pattern contains a wildcard, as we are unable to reason about whether a pattern overrides a previous pattern in a sane way. This happens for example in the case where a gitignore file contains "*.c" and "!src/*.c", where we wouldn't un-ignore files inside of the "src/" subdirectory. In this case, the first solution coming to mind may be to just strip the "src/" prefix and simply compare the basenames. While that would work here, it would stop working as soon as the basename pattern itself is different, like for example with "*x.c" and "!src/*.c. As such, we settle for the easier fix of just not optimizing away rules that contain a wildcard.
Patrick Steinhardt cda18f9b 2017-10-06T11:24:11 refs: do not use peeled OID if peeling to a tag If a reference stored in a packed-refs file does not directly point to a commit, tree or blob, the packed-refs file will also will include a fully-peeled OID pointing to the first underlying object of that type. If we try to peel a reference to an object, we will use that peeled OID to speed up resolving the object. As a reference for an annotated tag does not directly point to a commit, tree or blob but instead to the tag object, the packed-refs file will have an accomodating fully-peeled OID pointing to the object referenced by that tag. When we use the fully-peeled OID pointing to the referenced object when peeling, we obviously cannot peel that to the tag anymore. Fix this issue by not using the fully-peeled OID whenever we want to peel to a tag. Note that this does not include the case where we want to resolve to _any_ object type. Existing code may make use from the fact that we resolve those to commit objects instead of tag objects, even though that behaviour is inconsistent between packed and loose references. Furthermore, some tests of ours make the assumption that we in fact resolve those references to a commit.

Patrick Steinhardt a180e7d9 2017-06-13T11:10:19 tests: odb: add more low-level backend tests Introduce a new test suite "odb::backend::simple", which utilizes the fake backend to exercise the ODB abstraction layer. While such tests already exist for the case where multiple backends are put together, no direct testing for functionality with a single backend exist yet.
Patrick Steinhardt b2e53f36 2017-06-13T11:39:36 tests: odb: implement `exists_prefix` for the fake backend The fake backend currently implements all reading functions except for the `exists_prefix` one. Implement it to enable further testing of the ODB layer.
Patrick Steinhardt 983e627d 2017-06-13T11:38:59 tests: odb: use correct OID length The `search_object` function takes the OID length as one of its parameters, where its maximum length is `GIT_OID_HEXSZ`. The `exists` function of the fake backend used `GIT_OID_RAWSZ` though, leading to only the first half of the OID being used when finding the correct object.
Patrick Steinhardt c4cbb3b1 2017-06-13T11:38:14 tests: odb: have the fake backend detect ambiguous prefixes In order to be able to test the ODB prefix functions, we need to be able to detect ambiguous prefixes in case multiple objects with the same prefix exist in the fake ODB. Extend `search_object` to detect ambiguous queries and have callers return its error code instead of always returning `GIT_ENOTFOUND`.
Patrick Steinhardt 95170294 2017-06-13T11:08:28 tests: core: test initialization of `git_proxy_options` Initialization of the `git_proxy_options` structure is never tested anywhere. Include it in our usual initialization test in "core::structinit::compare".
Patrick Steinhardt bee423cc 2017-06-13T10:29:23 tests: network: add missing include for `git_repository_new` A newly added test uses the `git_repository_new` function without the corresponding header file being included. While this works due to the compiler deducing the correct function signature, we should obviously just include the function's declaration file.

Patrick Steinhardt f148258a 2017-06-12T16:19:45 tests: odb: add tests with multiple backends Previous to pulling out and extending the fake backend, it was quite cumbersome to write tests for very specific scenarios regarding backends. But as we have made it more generic, it has become much easier to do so. As such, this commit adds multiple tests for scenarios with multiple backends for the ODB. The changes also include a test for a very targeted scenario. When one backend found a matching object via `read_prefix`, but the last backend returns `GIT_ENOTFOUND` and when object hash verification is turned off, we fail to reset the error code to `GIT_OK`. This causes us to segfault later on, when doing a double-free on the returned object.
Patrick Steinhardt 6e010bb1 2017-06-12T15:43:56 tests: odb: allow passing fake objects to the fake backend Right now, the fake backend is quite restrained in the way how it works: we pass it an OID which it is to return later as well as an error code we want it to return. While this is sufficient for existing tests, we can make the fake backend a little bit more generic in order to allow us testing for additional scenarios. To do so, we change the backend to not accept an error code and OID which it is to return for queries, but instead a simple array of OIDs with their respective blob contents. On each query, the fake backend simply iterates through this array and returns the first matching object.
Patrick Steinhardt 369cb45f 2017-06-12T15:21:58 tests: do not reuse OID from backend In order to make the fake backend more useful, we want to enable it holding multiple object references. To do so, we need to decouple it from the single fake OID it currently holds, which we simply move up into the calling tests.
Patrick Steinhardt 2add34d0 2017-06-12T14:53:46 tests: odb: move fake backend into its own file The fake backend used by the test suite `odb::backend::nonrefreshing` is useful to have some low-level tests for the ODB layer. As such, we move the implementation into its own `backend_helpers` module.

Edward Thomson d2c4f764 2017-06-11T09:54:04 Merge pull request #4260 from libgit2/ethomson/forced_checkout_2 Update to forced checkout and untracked files
Patrick Steinhardt 0ef405b3 2017-02-15T14:05:10 checkout: do not delete directories with untracked entries If the `GIT_CHECKOUT_FORCE` flag is given to any of the `git_checkout` invocations, we remove files which were previously staged. But while doing so, we unfortunately also remove unstaged files in a directory which contains at least one staged file, resulting in potential data loss. This commit adds two tests to verify behavior.
Patrick Steinhardt 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.
Patrick Steinhardt 92d3ea4e 2017-05-19T13:04:32 tests: index::version: improve write test for index v4 The current write test does not trigger some edge-cases in the index version 4 path compression code. Rewrite the test to start off the an empty standard repository, creating index entries with interesting paths itself. This allows for more fine-grained control over checked paths. Furthermore, we now also verify that entry paths are actually reconstructed correctly.
Patrick Steinhardt 8fe33538 2017-05-19T12:45:48 tests: index::version: verify we write compressed index entries While we do have a test which checks whether a written index of version 4 has the correct version set, we do not check whether this actually enables path compression for index entries. This commit adds a new test by adding a number of index entries with equal path prefixes to the index and subsequently flushing that to disk. With suffix compression enabled by index version 4, only the last few bytes of these paths will actually have to be written to the index, saving a lot of disk space. For the test, differences are about an order of magnitude, allowing us to easily verify without taking a deeper look at actual on-disk contents.
Patrick Steinhardt 82368b1b 2017-05-12T10:04:42 tests: index::version: add test to read index version v4 While we have a simple test to determine whether we can write an index of version 4, we never verified that we are able to read this kind of index (and in fact, we were not able to do so). Add a new repository which has an index of version 4. This repository is then read from a new test.
Patrick Steinhardt fea0c81e 2017-05-12T09:09:07 tests: index::version: move up cleanup function The init and cleanup functions for test suites are usually prepended to our actual tests. The index::version test suite does not adhere to this stile. Fix this.
Patrick Steinhardt 8a5e7aae 2017-05-22T12:53:44 varint: fix computation for remaining buffer space When encoding varints to a buffer, we want to remain sure that the required buffer space does not exceed what is actually available. Our current check does not do the right thing, though, in that it does not honor that our `pos` variable counts the position down instead of up. As such, we will require too much memory for small varints and not enough memory for big varints. Fix the issue by correctly calculating the required size as `(sizeof(varint) - pos)`. Add a test which failed before.

Chris Hescock c0e54155 2017-01-11T10:39:59 indexer: name pack files after trailer hash Upstream git.git has changed the way how packfiles are named. Previously, they were using a hash of the contained object's OIDs, which has then been changed to use the hash of the complete packfile instead. See 1190a1acf (pack-objects: name pack files after trailer hash, 2013-12-05) in the git.git repository for more information on this change. This commit changes our logic to match the behavior of core git.
Patrick Steinhardt 2696c5c3 2017-05-19T09:21:17 repository: make check if repo is a worktree more strict To determine if a repository is a worktree or not, we currently check for the existence of a "gitdir" file inside of the repository's gitdir. While this is sufficient for non-broken repositories, we have at least one case of a subtly broken repository where there exists a gitdir file inside of a gitmodule. This will cause us to misidentify the submodule as a worktree. While this is not really a fault of ours, we can do better here by observing that a repository can only ever be a worktree iff its common directory and dotgit directory are different. This allows us to make our check whether a repo is a worktree or not more strict by doing a simple string comparison of these two directories. This will also allow us to do the right thing in the above case of a broken repository, as for submodules these directories will be the same. At the same time, this allows us to skip the `stat` check for the "gitdir" file for most repositories.

Patrick Steinhardt 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.
Patrick Steinhardt 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.
Patrick Steinhardt ffd264d9 2017-05-03T14:51:23 tests: repo: fix repo discovery tests on overlayfs Debian and Ubuntu often use schroot to build their DEB packages in a controlled environment. Depending on how schroot is configured, our tests regarding repository discovery break due to not being able to find the repositories anymore. It turns out that these errors occur when the schroot is configured to use an overlayfs on the directory structures. The reason for this failure is that we usually refrain from discovering repositories across devices. But unfortunately, overlayfs does not have consistent device identifiers for all its files but will instead use the device number of the filesystem the file stems from. So whenever we cross boundaries between the upper and lower layer of the overlay, we will fail to properly detect the repository and bail out. This commit fixes the issue by enabling cross-device discovery in our tests. While it would be preferable to have this turned off, it probably won't do much harm anyway as we set up our tests in a temporary location outside of the parent repository.
Patrick Steinhardt 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.

Patrick Steinhardt 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.
Patrick Steinhardt 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.
Patrick Steinhardt d59dabe5 2017-04-10T09:00:51 tests: object: test looking up corrupted objects We currently have no tests which check whether we fail reading corrupted objects. Add one which modifies contents of an object stored on disk and then tries to read the object.
Patrick Steinhardt 86c03552 2017-04-10T09:27:04 tests: object: create sandbox The object::lookup tests do use the "testrepo.git" repository in a read-only way, so we do not set up the repository as a sandbox but simply open it. But in a future commit, we will want to test looking up objects which are corrupted in some way, which requires us to modify the on-disk data. Doing this in a repository without creating the sandbox will modify contents of our libgit2 repository, though. Create the repository in a sandbox to avoid this.
Patrick Steinhardt e29e8029 2017-04-10T10:31:22 tests: odb: make hash of fake backend configurable In the odb::backend::nonrefreshing test suite, we set up a fake backend so that we are able to determine if backend functions are called correctly. During the setup, we also parse an OID which is later on used to read out the pseudo-object. While this procedure works right now, it will create problems later when we implement hash verification for looked up objects. The current OID ("deadbeef") will not match the hash of contents we give back to the ODB layer and thus cannot be verified. Make the hash configurable so that we can simply switch the returned for single tests.

Patrick Steinhardt cf07db2f 2017-04-07T16:05:10 filter: only close filter if it's been initialized correctly In the function `git_filter_list_stream_data`, we initialize, write and subesquently close the stream which should receive content processed by the filter. While we skip writing to the stream if its initialization failed, we still try to close it unconditionally -- even if the initialization failed, where the stream might not be set at all, leading us to segfault. Semantics in this code is not really clear. The function handling the same logic for files instead of data seems to do the right thing here in only closing the stream when initialization succeeded. When stepping back a bit, this is only reasonable: if a stream cannot be initialized, the caller would not expect it to be closed again. So actually, both callers of `stream_list_init` fail to do so. The data streaming function will always close the stream and the file streaming function will not close the stream if writing to it has failed. The fix is thus two-fold: - callers of `stream_list_init` now close the stream iff it has been initialized - `stream_list_init` now closes the lastly initialized stream if the current stream in the chain failed to initialize Add a test which segfaulted previous to these changes.

E.g. having a submodule with URL "../submodule" will look for the submodule at "repo/../submodule". With the introduction of worktrees, though, we cannot simply resolve the URL relative to the repository location itself. If the repository for which a URL is to be resolved is a working tree, we have to resolve the URL relative to the parent's repository path. Otherwise, the URL would change depending on where the working tree is located. Fix this by special-casing when we have a working tree while getting the URL base.
Patrick Steinhardt 097f0105 2017-03-17T08:54:53 refdb: create references in commondir References for a repository are usually created inside of its gitdir. When using worktrees, though, these references are not to be created inside the worktree gitdir, but instead inside the gitdir of its parent repository, which is the commondir. Like this, branches will still be available after the worktree itself has been deleted. The filesystem refdb currently still creates new references inside of the gitdir. Fix this and have it create references in commondir.
Patrick Steinhardt 8f154be3 2017-03-17T08:13:59 worktree: write resolved paths into link files The three link files "worktree/.git", ".git/worktrees/<name>/commondir" and ".git/worktrees/<name>/gitdir" should always contain absolute and resolved paths. Adjust the logic creating new worktrees to first use `git_path_prettify_dir` before writing out these files, so that paths are resolved first.
Patrick Steinhardt 20a368e2 2017-03-15T15:29:29 worktree: parent path should point to the working dir The working tree's parent path should not point to the parent's gitdir, but to the parent's working directory. Pointing to the gitdir would not make any sense, as the parent's working directory is actually equal to both repository's common directory. Fix the issue.
Patrick Steinhardt 3017ba94 2017-03-15T14:24:25 worktree: implement `git_worktree_open_from_repository` While we already provide functionality to look up a worktree from a repository, we cannot do so the other way round. That is given a repository, we want to look up its worktree if it actually exists. Getting the worktree of a repository is useful when we want to get certain meta information like the parent's location, getting the locked status, etc.

Patrick Steinhardt c0eba379 2017-03-14T11:01:19 diff_parse: correctly set options for parsed diffs The function `diff_parsed_alloc` allocates and initializes a `git_diff_parsed` structure. This structure also contains diff options. While we initialize its flags, we fail to do a real initialization of its values. This bites us when we want to actually use the generated diff as we do not se the option's version field, which is required to operate correctly. Fix the issue by executing `git_diff_init_options` on the embedded struct.
Patrick Steinhardt ad5a909c 2017-03-14T09:39:37 patch_parse: fix parsing minimal trailing diff line In a diff, the shortest possible hunk with a modification (that is, no deletion) results from a file with only one line with a single character which is removed. Thus the following hunk @@ -1 +1 @@ -a + is the shortest valid hunk modifying a line. The function parsing the hunk body though assumes that there must always be at least 4 bytes present to make up a valid hunk, which is obviously wrong in this case. The absolute minimum number of bytes required for a modification is actually 2 bytes, that is the "+" and the following newline. Note: if there is no trailing newline, the assumption will not be offended as the diff will have a line "\ No trailing newline" at its end. This patch fixes the issue by lowering the amount of bytes required.
Patrick Steinhardt ace3508f 2017-03-14T10:37:47 patch_generate: fix `git_diff_foreach` only working with generated diffs The current logic of `git_diff_foreach` makes the assumption that all diffs passed in are actually derived from generated diffs. With these assumptions we try to derive the actual diff by inspecting either the working directory files or blobs of a repository. This obviously cannot work for diffs parsed from a file, where we do not necessarily have a repository at hand. Since the introduced split of parsed and generated patches, there are multiple functions which help us to handle patches generically, being indifferent from where they stem from. Use these functions and remove the old logic specific to generated patches. This allows re-using the same code for invoking the callbacks on the deltas.

Even if the submodule's SHA is changed, and that file would conflict with a new tracked file, it's still OK to start the rebase and discover the conflict later.
