Patrick Steinhardt 8d93a11c 2017-05-03T12:38:55 odb: fix printf formatter for git_off_t The fields `declared_size` and `received_bytes` of the `git_odb_stream` are both of type `git_off_t` which is defined as a signed integer. When passing these values to a printf-style string in `git_odb_stream__invalid_length`, though, we format these as PRIuZ, which is unsigned. Fix the issue by using PRIdZ instead, silencing warnings on macOS.
Patrick Steinhardt 7776db51 2017-05-03T12:15:12 odb: shut up gcc warnings regarding uninitilized variables The `error` variable is used as a return value in the out-section of both `odb_read_1` and `read_prefix_1`. While the value will actually always be initialized inside of this section, GCC fails to realize this due to interactions with the `found` variable: if `found` is set, the error will always be initialized. If it is not, we return early without reaching the out-statements. Shut up the warnings by initializing the error variable, even though it is unnecessary.
Patrick Steinhardt 2ce2a48f 2017-05-02T13:37:15 transports: ssh: clean up after libssh2 on exit After calling `libssh2_init`, we need to clean up after the library by executing `libssh2_exit` as soon as we exit. Register a shutdown handler to do so which simply calls `libssh2_exit`. This fixes several memory leaks.
Patrick Steinhardt 8c027351 2017-05-02T13:35:09 transports: ssh: report failure initializing libssh2 We unconditionally return success when initializing libssh2, regardless of whether `libgssh2_init` signals success or an error. Fix this by checking its return code.

Patrick Steinhardt e0973bc0 2017-04-28T14:05:15 odb: verify hashes in read_prefix_1 While the function reading an object from the complete OID already verifies OIDs, we do not yet do so for reading objects from a partial OID. Do so when strict OID verification is enabled.
Patrick Steinhardt 14109620 2017-04-28T14:03:54 odb: improve error handling in read_prefix_1 The read_prefix_1 function has several return statements springled throughout the code. As we have to free memory upon getting an error, the free code has to be repeated at every single retrun -- which it is not, so we have a memory leak here. Refactor the code to use the typical `goto out` pattern, which will free data when an error has occurred. While we're at it, we can also improve the error message thrown when multiple ambiguous prefixes are found. It will now include the colliding prefixes.
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.

Edward Thomson cecd41fb 2017-04-26T09:08:51 Merge pull request #4217 from pks-t/pks/readonly-cfg-backend Honor read-only flag when writing to config backends
Patrick Steinhardt 954e06a8 2017-04-26T12:09:57 socket_stream: continue to next addrinfo on socket creation failure When connecting to a remote via socket stream, we first use getaddrinfo to obtain the possible connection methods followed by creating and connecting the socket. But when creating the socket, we error out as soon as we get an invalid socket instead of trying out other address hints returned by addrinfo. Fix this by continuing on invalid socket instead of returning an error. This fixes connection establishment with musl libc.
Patrick Steinhardt 95f29fb3 2017-04-25T12:40:13 config: skip r/o backends when writing Configuration backends have a readonly-flag which is currently used to distinguish configuration snapshots. But somewhat unexpectedly, we do not use the flag to prevent writing to a readonly backend but happily proceed to do so. This commit modifies logic to also honor the readonly flag for configuration setters. We will now traverse through all backends and pick the first one which is not marked as read-only whenever we want to write new configuration.
Patrick Steinhardt 64244131 2017-04-25T12:59:48 config_file: add missing include for `git_config_backend` The config_file.h header provides some inline declarations accessing the `git_config_backend`, but misses its declaration. Add the missing include for "git2/sys/config.h" to add it.

This simple commit actually introduced a segfault in that we now try to free the pointer to the allocated diff in an error case, instead of the allocated diff itself. This commit fixes the issue.

Patrick Steinhardt 38b6e700 2017-04-12T08:09:08 fileops: fix leaking fd in `mmap_ro_file` When the `git_futils_mmap_ro_file` function encounters an error after the file has been opened, it will do a simple returns. Instead, we should close the opened file descriptor to avoid a leak. This commit fixes the issue.
Edward Thomson d476d024 2017-04-11T19:18:05 Merge pull request #4196 from pks-t/pks/filter-segfault filter: only close filter if it's been initialized correctly
Patrick Steinhardt 88520151 2017-04-07T13:02:50 openssl_stream: use new initialization function on OpenSSL version >=1.1 Previous to OpenSSL version 1.1, the user had to initialize at least the error strings as well as the SSL algorithms by himself. OpenSSL version 1.1 instead provides a new function `OPENSSL_init_ssl`, which handles initialization of all subsystems. As the new API call will by default load error strings and initialize the SSL algorithms, we can safely replace these calls when compiling against version 1.1 or later. This fixes a compiler error when compiling against OpenSSL version 1.1 which has been built without stubs for deprecated syntax.
Patrick Steinhardt 29081c2f 2017-04-07T12:54:33 openssl_stream: remove locking initialization on OpenSSL version >=1.1 Up to version 1.0, OpenSSL required us to provide a callback which implements a locking mechanism. Due to problems in the API design though this mechanism was inherently broken, especially regarding that the locking callback cannot report errors in an obvious way. Due to this shortcoming, the locking initialization has been completely removed in OpenSSL version 1.1. As the library has also been refactored to not make any use of these callback functions, we can safely remove all initialization of the locking subsystem if compiling against OpenSSL version 1.1 or higher. This fixes a compilation error when compiling against OpenSSL version 1.1 which has been built without stubs for deprecated syntax.
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.

Patrick Steinhardt 2a485dab 2017-04-04T18:55:57 refs: update worktree HEADs when renaming branches Whenever we rename a branch, we update the repository's symbolic HEAD reference if it currently points to the branch that is to be renamed. But with the introduction of worktrees, we also have to iterate over all HEADs of linked worktrees to adjust them. Do so.
Patrick Steinhardt 38fc5ab0 2017-04-04T18:44:43 branch: use `foreach_head` to see if a branch is checked out Previously, we have extracted the logic to find and iterate over all HEADs of a repository. Use this function in `git_branch_is_checked_out`.
Patrick Steinhardt 74511aa2 2017-04-04T18:44:29 repository: add function to iterate over all HEADs While we already provide functions to get the current repository's HEAD, it is quite involved to iterate over HEADs of both the repository and all linked work trees. This commit implements a function `git_repository_foreach_head`, which accepts a callback which is then called for all HEAD files.
Patrick Steinhardt 3e84aa50 2017-04-05T13:47:09 repository: get worktree HEAD via `git_reference__read_head` The functions `git_repository_head_for_worktree` and `git_repository_detached_head_for_worktree` both implement their own logic to read the HEAD reference file. Use the new function `git_reference__read_head` instead to unify the code paths.
Patrick Steinhardt 987f5659 2017-04-04T17:12:22 repository: extract function to get path to a file in a work tree The function `read_worktree_head` has the logic embedded to construct the path to `HEAD` in the work tree's git directory, which is quite useful for other callers. Extract the logic into its own function to make it reusable by others.
Patrick Steinhardt 8242cc1a 2017-04-04T18:18:45 repository: set error message if trying to set HEAD to a checked out one If trying to set the HEAD of a repository to another reference, we have to check whether this reference is already checked out in another linked work tree. If it is, we will refuse setting the HEAD and return an error, but do not set a meaningful error message. Add one.
Patrick Steinhardt 5b65ac25 2017-04-05T10:43:18 refs: implement function to read references from file Currently, we only provide functions to read references directly from a repository's reference store via e.g. `git_reference_lookup`. But in some cases, we may want to read files not connected to the current repository, e.g. when looking up HEAD of connected work trees. This commit implements `git_reference__read_head`, which will read out and allocate a reference at an arbitrary path.
Edward Thomson 89d403cc 2017-04-05T09:50:12 win32: enable `p_utimes` for readonly files Instead of failing to set the timestamp of a read-only file (like any object file), set it writable temporarily to update the timestamp.
Patrick Steinhardt 9daba9f4 2017-03-28T10:12:23 fileops: do not overwrite correct error message on mmap When executing `git_futils_mmap_ro_file`, we first try to guess whether the file is mmapable at all. Part of this check is whether the file is too large to be mmaped, which can be true on systems with 32 bit `size_t` types. The check is performed by first getting the file size wtih `git_futils_filesize` and then checking whether the returned size can be represented as `size_t`, returning an error if so. While this test also catches the case where the function returned an error (as `-1` is not representable by `size_t`), we will set the misleading error message "file too large to mmap". But in fact, a negative return value from `git_futils_filesize` will be caused by the inability to fstat the file. Fix the error message by handling negative return values separately and not overwriting the error message in that case.
Patrick Steinhardt 756138e4 2017-03-28T09:15:53 blame_git: check return value of `git__calloc` We do not check the return value of `git__calloc`, which may return `NULL` in out-of-memory situations. Fix the error by using `GITERR_CHECK_ALLOC`.
Patrick Steinhardt a76d7502 2017-03-28T09:12:34 path: short-circuit `git_path_apply_relative` on error Short-circuit the call to `git_path_resolve_relative` in case `git_buf_joinpath` returns an error. While this does not fix any immediate errors, the resulting code is easier to read and handles potential new error conditions raised by `git_buf_joinpath`.
Patrick Steinhardt cffd616a 2017-03-28T09:08:41 path: handle error returned by `git_buf_joinpath` In the `_check_dir_contents` function, we first allocate memory for joining the directory and subdirectory together and afterwards use `git_buf_joinpath`. While this function in fact should not fail as memory is already allocated, err on the safe side and check for returned errors.
Patrick Steinhardt 4467aeac 2017-03-28T09:00:48 config_file: handle errors other than OOM while parsing section headers The current code in `parse_section_header_ext` is only prepared to properly handle out-of-memory conditions for the `git_buf` structure. While very unlikely and probably caused by a programming error, it is also possible to run into error conditions other than out-of-memory previous to reaching the actual parsing loop. In these cases, we will run into undefined behavior as the `rpos` variable is only initialized after these triggerable errors, but we use it in the cleanup-routine. Fix the issue by unifying the function's cleanup code with an `end_error` section, which will not use the `rpos` variable.
Edward Thomson 7ece9065 2017-04-03T23:07:16 win32: make posix emulation retries configurable POSIX emulation retries should be configurable so that tests can disable them. In particular, maniacally threading tests may end up trying to open locked files and need retries, which will slow continuous integration tests significantly.

Patrick Steinhardt 06abbb7f 2017-03-27T13:14:48 treebuilder: exit early if running OOM in `write_with_buffer` While writing the tree inside of a buffer, we check whether the buffer runs out of memory after each tree entry. While we set the error code as soon as we detect the OOM situation, we happily proceed iterating over the entries. This is not useful at all, as we will try to write into the buffer repeatedly, which cannot work. Fix this by exiting as soon as we are OOM.

While we correctly initialized up to `n` locks, as determined by `CRYPTO_num_locks`, we were repeatedly freeing the same mutex in our shutdown procedure. Fix the issue by freeing locks at the correct index.

Patrick Steinhardt 94af9155 2017-03-20T09:01:18 map: remove `*map_free` macros The `map_free` functions were not implemented as functions but instead as macros which also set the map to NULL. While this is most certainly sensible in most cases, we should prefer the more obvious behavior, namingly leaving the map pointer intact. Furthermore, this macro has been refactored incorrectly during the map-refactorings: the two statements are not actually grouped together by a `do { ... } while (0)` block, as it is required for macros to match the behavior of functions more closely. This has led to at least one subtle nesting error in `pack-objects.c`. The following code block ``` if (pb->object_ix) git_oidmap_free(pb->object_ix); ``` would be expanded to ``` if (pb->object_ix) git_oidmap__free(pb->object_ix); pb->object_ix = NULL; ``` which is not what one woudl expect. While it is not a bug here as it would simply become a no-op, the wrong implementation could lead to bugs in other occasions. Fix this by simply removing the macro altogether and replacing it with real function calls. This leaves the burden of setting the pointer to NULL afterwards to the caller, but this is actually expected and behaves like other `free` functions.
Patrick Steinhardt 77c8ee74 2017-03-20T08:59:30 checkout: fix double-free of checkout_data's mkdir_map We currently call `git_strmap_free` on `checkout_data.mkdir_map` in the `checkout_data_clear` function. The only thing protecting us from a double-free is that the `git_strmap_free` function is in fact not a function, but a macro that also sets the map to NULL. Remove the second call to `git_strmap_free` and explicitly set the map member to NULL.
Patrick Steinhardt b0c9bc92 2017-03-15T13:38:54 submodule: resolve URLs relative to main worktree It is possible to specify submodule URLs relative to the repository location. 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 9dcc79bc 2017-03-15T16:35:43 worktree: use fully qualified reference name for created HEAD When creating a new worktree, we have to set up the initial data structures. Next to others, this also includes the HEAD pseudo-ref. We currently set it to the worktree respectively branch name, which is actually not fully qualified. Use the fully qualified branch name instead.
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 dfc98706 2017-03-15T13:54:14 worktree: split off function opening working directory Separate the logic of finding the worktree directory of a repository and actually opening the working tree's directory. This is a preparatory step for opening the worktree structure of a repository itself.
Patrick Steinhardt 3e9c5d8a 2017-03-15T13:42:52 worktree: have `is_worktree_dir` accept a string instead of buffer This will be used in later commits, where it becomes cumbersome to always pass in a buffer.
