Edward Thomson bc35fd4b 2017-07-18T14:44:29 win32: provide fast-path for retrying filesystem operations When using the `do_with_retries` macro for retrying filesystem operations in the posix emulation layer, allow the remediation function to return `GIT_RETRY`, meaning that the error was believed to be remediated, and the operation should be retried immediately, without a sleep. This is a slightly more general solution to the problem fixed in #4312.
Carson Howard 1bcdaba2 2017-07-18T14:47:28 fixed win32 p_unlink retry sleep issue Fixed an issue where the retry logic on p_unlink sleeps before it tries setting a file to write mode causing unnecessary slowdown.
Carlos Martín Nieto d1dbb3ae 2017-07-12T07:40:16 signature: don't leave a dangling pointer to the strings on parse failure If the signature is invalid but we detect that after allocating the strings, we free them. We however leave that pointer dangling in the structure the caller gave us, which can lead to double-free. Set these pointers to `NULL` after freeing their memory to avoid this.

Patrick Steinhardt 4dc87e72 2017-06-21T13:35:46 merge: fix potential free of uninitialized memory The function `merge_diff_mark_similarity_exact` may error our early and, when it does so, free the `ours_deletes_by_oid` and `theirs_deletes_by_oid` variables. While the first one can never be uninitialized due to the first call actually assigning to it, the second variable can be freed without being initialized. Fix the issue by initializing both variables to `NULL`.

Edward Thomson cb3010c5 2017-06-12T12:56:40 odb_read_prefix: reset error in backends loop When looking for an object by prefix, we query all the backends so that we can ensure that there is no ambiguity. We need to reset the `error` value between backends; otherwise the first backend may find an object by prefix, but subsequent backends may not. If we do not reset the `error` value then it will remain at `GIT_ENOTFOUND` and `read_prefix_1` will fail, despite having actually found an object.

Edward Thomson 83989d70 2017-06-08T22:23:53 checkout: cope with untracked files in directory deletion When deleting a directory during checkout, do not simply delete the directory, since there may be untracked files. Instead, go into the iterator and examine each file. In the original code (the code with the faulty assumption), we look to see if there's an index entry beneath the directory that we want to remove. Eg, it looks to see if we have a workdir entry foo and an index entry foo/bar.txt. If this is not the case, then the working directory must have precious files in that directory. This part is okay. The part that's not okay is if there is an index entry foo/bar.txt. It just blows away the whole damned directory. That's not cool. Instead, by simply pushing the directory itself onto the stack and iterating each entry, we will deal with the files one by one - whether they're in the index (and can be force removed) or not (and are precious). The original code was a bad optimization, assuming that we didn't need to git_iterator_advance_into if there was any index entry in the folder. That's wrong - we could have optimized this iff all folder entries are in the index. Instead, we need to simply dig into the directory and analyze its entries.
Roger Gee e141f079 2017-06-10T11:46:09 smart_protocol: fix parsing of server ACK responses Fix ACK parsing in wait_while_ack() internal function. This patch handles the case where multi_ack_detailed mode sends 'ready' ACKs. The existing functionality would bail out too early, thus causing the processing of the ensuing packfile to fail if/when 'ready' ACKs were sent.
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 a693b873 2017-06-07T10:20:44 buffer: use `git_buf_init` with length The `git_buf_init` function has an optional length parameter, which will cause the buffer to be initialized and allocated in one step. This can be used instead of static initialization with `GIT_BUF_INIT` followed by a `git_buf_grow`. This patch does so for two functions where it is applicable.
Patrick Steinhardt 4796c916 2017-06-07T09:56:31 buffer: return errors for `git_buf_init` and `git_buf_attach` Both the `git_buf_init` and `git_buf_attach` functions may call `git_buf_grow` in case they were given an allocation length as parameter. As such, it is possible for these functions to fail when we run out of memory. While it won't probably be used anytime soon, it does indeed make sense to also record this fact by returning an error code from both functions. As they belong to the internal API only, this change does not break our interface.
Patrick Steinhardt 9a8386a2 2017-06-07T09:50:54 buffer: consistently use `ENSURE_SIZE` to grow buffers on-demand The `ENSURE_SIZE` macro can be used to grow a buffer if its currently allocated size does not suffice a required target size. While most of the code already uses this macro, the `git_buf_join` and `git_buf_join3` functions do not yet use it. Due to the macro first checking whether we have to grow the buffer at all, this has the benefit of saving a function call when it is not needed. While this is nice to have, it will probably not matter at all performance-wise -- instead, this only serves for consistency across the code.
Patrick Steinhardt e82dd813 2017-06-08T11:52:32 buffer: fix `ENSURE_SIZE` macro referencing wrong variable While the `ENSURE_SIZE` macro gets a reference to both the buffer that is to be resized and a new size, we were not consistently referencing the passed buffer, but instead a variable `buf`, which is not passed in. Funnily enough, we never noticed because our buffers seem to always be named `buf` whenever the macro was being used. Fix the macro by always using the passed-in buffer. While at it, add braces around all mentions of passed-in variables as should be done with macros to avoid subtle errors. Found-by: Edward Thompson
Patrick Steinhardt 97eb5ef0 2017-06-07T10:05:54 buffer: rely on `GITERR_OOM` set by `git_buf_try_grow` The function `git_buf_try_grow` consistently calls `giterr_set_oom` whenever growing the buffer fails due to insufficient memory being available. So in fact, we do not have to do this ourselves when a call to any buffer-growing function has failed due to an OOM situation. But we still do so in two functions, which this patch cleans up.

Marc-Antoine Perennou f28744a5 2017-06-05T10:11:20 openssl_stream: fix building with libressl OpenSSL v1.1 has introduced a new way of initializing the library without having to call various functions of different subsystems. In libgit2, we have been adapting to that change with 88520151f (openssl_stream: use new initialization function on OpenSSL version >=1.1, 2017-04-07), where we added an #ifdef depending on the OpenSSL version. This change broke building with libressl, though, which has not changed its API in the same way. Fix the issue by expanding the #ifdef condition to use the old way of initializing with libressl.

Patrick Steinhardt 064a60e9 2017-05-19T14:06:15 index: verify we have enough space left when writing index entries In our code writing index entries, we carry around a `disk_size` representing how much memory we have in total and pass this value to `git_encode_varint` to do bounds checks. This does not make much sense, as at the time when passing on this variable it is already out of date. Fix this by subtracting used memory from `disk_size` as we go along. Furthermore, assert we've actually got enough space left to do the final path memcpy.
Patrick Steinhardt c71dff7e 2017-05-19T13:49:34 index: fix shared prefix computation when writing index entry When using compressed index entries, each entry's path is preceded by a varint encoding how long the shared prefix with the previous index entry actually is. We currently encode a length of `(path_len - same_len)`, which is doubly wrong. First, `path_len` is already set to `path_len - same_len` previously. Second, we want to encode the shared prefix rather than the un-shared suffix length. Fix this by using `same_len` as the varint value instead.
Patrick Steinhardt 83e0392c 2017-05-19T13:39:05 index: also sanity check entry size with compressed entries We have a check in place whether the index has enough data left for the required footer after reading an index entry, but this was only used for uncompressed entries. Move the check down a bit so that it is executed for both compressed and uncompressed index entries.
Patrick Steinhardt 350d2c47 2017-05-19T14:22:35 index: remove file-scope entry size macros All index entry size computations are now performed in `index_entry_size`. As such, we do not need the file-scope macros for computing these sizes anymore. Remove them and move the `entry_size` macro into the `index_entry_size` function.
Patrick Steinhardt 46b67034 2017-05-19T13:59:53 index: don't right-pad paths when writing compressed entries Our code to write index entries to disk does not check whether the entry that is to be written should use prefix compression for the path. As such, we were overallocating memory and added bogus right-padding into the resulting index entries. As there is no padding allowed in the index version 4 format, this should actually result in an invalid index. Fix this by re-using the newly extracted `index_entry_size` function.
Patrick Steinhardt 29f498e0 2017-05-19T13:38:34 index: move index entry size computation into its own function Create a new function `index_entry_size` which encapsulates the logic to calculate how much space is needed for an index entry, whether it is simple/extended or compressed/uncompressed. This can later be re-used by our code writing index entries.
Patrick Steinhardt 8ceb890b 2017-05-19T12:35:21 index: set last written index entry in foreach-entry-loop The last written disk entry is currently being written inside of the function `write_disk_entry`. Make behavior a bit more obviously by instead setting it inside of `write_entries` while iterating all entries.
Patrick Steinhardt 11d0be23 2017-05-12T10:01:43 index: set last entry when reading compressed entries To calculate the path of a compressed index entry, we need to know the preceding entry's path. While we do actually set the first predecessor correctly to "", we fail to update this while reading the entries. Fix the issue by updating `last` inside of the loop. Previously, we've been passing a double-pointer to `read_entry`, which it didn't update. As it is more obvious to update the pointer inside the loop itself, though, we can simply convert it to a normal pointer.
Patrick Steinhardt febe8c14 2017-05-10T14:27:12 index: fix confusion with shared prefix in compressed path names The index version 4 introduced compressed path names for the entries. From the git.git index-format documentation: At the beginning of an entry, an integer N in the variable width encoding [...] is stored, followed by a NUL-terminated string S. Removing N bytes from the end of the path name for the previous entry, and replacing it with the string S yields the path name for this entry. But instead of stripping N bytes from the previous path's string and using the remaining prefix, we were instead simply concatenating the previous path with the current entry path, which is obviously wrong. Fix the issue by correctly copying the first N bytes of the previous entry only and concatenating the result with our current entry's path.
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 9f9fd05f 2017-05-19T08:59:46 repository: factor out worktree check The check whether a repository is a worktree or not is currently done inside of `git_repository_open_ext`. As we want to extend this function later on, pull it out into its own function `repo_is_worktree` to ease working on it.
Patrick Steinhardt 32841973 2017-05-19T08:38:47 repository: improve parameter names for `find_repo` The out-parameters of `find_repo` containing found paths of a repository are a tad confusing, as they are not as obvious as they could be. Rename them like following to ease reading the code: - `repo_path` -> `gitdir_path` - `parent_path` -> `workdir_path` - `link_path` -> `gitlink_path` - `common_path` -> `commondir_path`
Patrick Steinhardt 57121a23 2017-05-19T08:34:32 repository: clear out-parameter instead of freeing it The `path` out-parameter of `find_repo` is being sanitized initially such that we do not try to append to existing content. The sanitization is done via `git_buf_free`, though, which forces us to needlessly reallocate the buffer later in the function. Fix this by using `git_buf_clear` instead.
Michael Tesch cee1e7af 2017-04-12T14:38:30 merge: perform exact rename detection in linear time The current exact rename detection has order n^2 complexity. We can do better by using a map to first aggregate deletes and using that to match deletes to adds. This results in a substantial performance improvement for merges with a large quantity of adds and deletes.

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.
William Bain 8b107dc5 2017-05-03T11:20:57 revparse: support open-ended ranges Support '..' and '...' ranges where one side is not specified. The unspecified side defaults to HEAD. Closes #4223
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 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 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 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.

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 1cb30b1b 2017-04-25T09:48:59 diff_parse: free object instead of its pointer In e7330016a (diff_parse: check return value of `git_diff_init_options`, 2017-03-20), we've introduced an error check whether we're able to correctly initialize the diff options. 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.

Add a getter for these options to copy the proxy options into something external implementors can use.

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.
