Patrick Steinhardt ade0d9c6 2017-02-13T13:46:17 commit: avoid possible use-after-free When extracting a commit's signature, we first free the object and only afterwards put its signature contents into the result buffer. This works in most cases - the free'd object will normally be cached anyway, so we only end up decrementing its reference count without actually freeing its contents. But in some more exotic setups, where caching is disabled, this can definitly be a problem, as we might be the only instance currently holding a reference to this object. Fix this issue by first extracting the contents and freeing the object afterwards only.
Patrick Steinhardt dc851d9e 2017-02-13T13:42:16 commit: clear user-provided buffers The functions `git_commit_header_field` and `git_commit_extract_signature` both receive buffers used to hand back the results to the user. 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.
Patrick Steinhardt cdb2c2a0 2017-02-13T13:31:37 buffer: clarify how `git_buf_sanitize` handles non-NULL input When `git_buf_sanitize` gets called, it converts a buffer with NULL content to be correctly initialized. This is done by pointing it to `git_buf__initbuf`. While the method's documentation states this clearly, it may also lead to the conclusion that it will do the same to buffers which do _not_ have NULL contents. Clarify behavior when passing a buffer with non-NULL contents, where `git_buf_sanitize` will ensure that the contents are `\0`-terminated.

Patrick Steinhardt 1fd6e035 2016-11-07T10:23:34 worktree: test opening discovered submodule worktrees
Patrick Steinhardt 39abd3ad 2016-11-04T13:39:54 worktree: compute workdir for worktrees opened via their gitdir When opening a worktree via the gitdir of its parent repository we fail to correctly set up the worktree's working directory. The problem here is two-fold: we first fail to see that the gitdir actually is a gitdir of a working tree and then subsequently fail to determine the working tree location from the gitdir. The first problem of not noticing a gitdir belongs to a worktree can be solved by checking for the existence of a `gitdir` file in the gitdir. This file points back to the gitlink file located in the working tree's working directory. As this file only exists for worktrees, it should be sufficient indication of the gitdir belonging to a worktree. The second problem, that is determining the location of the worktree's working directory, can then be solved by reading the `gitdir` file in the working directory's gitdir. When we now resolve relative paths and strip the final `.git` component, we have the actual worktree's working directory location.
Patrick Steinhardt 84f56cb0 2016-11-04T11:59:52 repository: rename `path_repository` and `path_gitlink` The `path_repository` variable is actually confusing to think about, as it is not always clear what the repository actually is. It may either be the path to the folder containing worktree and .git directory, the path to .git itself, a worktree or something entirely different. Actually, the intent of the variable is to hold the path to the gitdir, which is either the .git directory or the bare repository. Rename the variable to `gitdir` to avoid confusion. While at it, also rename `path_gitlink` to `gitlink` to improve consistency.
Patrick Steinhardt 384518d0 2015-10-27T14:17:52 repository: restrict checking out checked out branches If a branch is already checked out in a working tree we are not allowed to check out that branch in another repository. Introduce this restriction when setting a repository's HEAD.
Patrick Steinhardt 143e539f 2015-11-06T12:33:59 branch: restrict branch deletion for worktrees Restrict the ability to delete branches that are checked out in any linked repository.
Patrick Steinhardt e3acd37b 2015-11-06T12:08:15 branch: implement `git_branch_is_checked_out` Implement a new function that is able to determine if a branch is checked out in any repository connected to the current repository. In particular, this is required to check if for a given repository and branch, there exists any working tree connected to that repository that is referencing this branch.
Patrick Steinhardt 4321595d 2015-11-10T16:54:48 worktree: test basic merge functionality
Patrick Steinhardt 04fb12ab 2015-10-27T12:37:51 worktree: implement functions reading HEAD Implement `git_repository_head_for_worktree` and `git_repository_head_detached_for_worktree` for directly accessing a worktree's HEAD without opening it as a `git_repository` first.
Patrick Steinhardt f0cfc341 2015-10-21T13:53:18 worktree: implement `git_worktree_prune` Implement the `git_worktree_prune` function. This function can be used to delete working trees from a repository. According to the flags passed to it, it can either delete the working tree's gitdir only or both gitdir and the working directory.
Patrick Steinhardt 2a503485 2015-10-21T16:03:04 worktree: implement locking mechanisms Working trees support locking by creating a file `locked` inside the tree's gitdir with an optional reason inside. Support this feature by adding functions to get and set the locking status.
Patrick Steinhardt dea7488e 2015-10-23T14:11:44 worktree: implement `git_worktree_add` Implement the `git_worktree_add` function which can be used to create new working trees for a given repository.
Patrick Steinhardt 372dc9ff 2015-10-21T13:49:55 worktree: implement `git_worktree_validate` Add a new function that checks wether a given `struct git_worktree` is valid. The validation includes checking if the gitdir, parent directory and common directory are present.
Patrick Steinhardt 8c8d726e 2015-10-21T12:10:30 worktree: implement `git_repository_open_from_worktree` Add function `git_repository_open_from_worktree`, which allows to open a `git_worktree` as repository.

Patrick Steinhardt d3bc09e8 2015-10-21T12:02:31 worktree: introduce `struct git_worktree` Introduce a new `struct git_worktree`, which holds information about a possible working tree connected to a repository. Introduce functions to allow opening working trees for a repository.
Patrick Steinhardt 45f2b7a4 2015-10-21T11:48:02 worktree: implement `git_worktree_list` Add new module for working trees with the `git_worktree_list` function. The function lists names for all working trees of a certain repository.
Patrick Steinhardt 854b5c70 2015-10-26T16:21:09 repository: expose `repo_init_create_head` Expose the function `repo_init_create_head` as `git_repository_create_head`.
Patrick Steinhardt 4292837d 2015-09-24T14:37:10 config: open configuration in commondir A repository's configuartion file can always be found in the GIT_COMMON_DIR, which has been newly introduced. For normal repositories this does change nothing, but for working trees this change allows to access the shared configuration file.
Patrick Steinhardt e9403024 2015-09-24T15:32:26 refdb: look for reflog in commondir
Patrick Steinhardt e0a6c28e 2015-09-16T16:09:24 refdb: introduce commondir awareness The refdb_fs_backend is not aware of the git commondir, which stores common objects like the o bject database and packed/loose refereensces when worktrees are used. Make refdb_fs_backend aware of the common directory by introducing a new commonpath variable that points to the actual common path of the database and using it instead of the gitdir for the mentioned objects.
Patrick Steinhardt 71dd0861 2015-09-17T11:40:55 refdb: rename refdb_fs_backend's .path to .gitpath The variable '.path' of the refdb_fs_backend struct becomes confusing regarding the introduction of the git commondir. It does not immediatly become obvious what it should point to. Fix this problem by renaming the variable to `gitpath`, clarifying that it acutally points to the `.git` directory of the repository, in contrast to the commonpath directory, which points to the directory containing shared objects like references and the object store.
Patrick Steinhardt 79ab3ef6 2015-10-15T15:58:05 repository: introduce is_worktree variable
Patrick Steinhardt c5f3da96 2016-11-11T14:36:43 repository: use `git_repository_item_path` The recent introduction of the commondir variable of a repository requires callers to distinguish whether their files are part of the dot-git directory or the common directory shared between multpile worktrees. In order to take the burden from callers and unify knowledge on which files reside where, the `git_repository_item_path` function has been introduced which encapsulate this knowledge. Modify most existing callers of `git_repository_path` to use `git_repository_item_path` instead, thus making them implicitly aware of the common directory.
Patrick Steinhardt c09fd54e 2015-09-16T12:10:11 repository: introduce commondir variable The commondir variable stores the path to the common directory. The common directory is used to store objects and references shared across multiple repositories. A current use case is the newly introduced `git worktree` feature, which sets up a separate working copy, where the backing git object store and references are pointed to by the common directory.
Patrick Steinhardt 807d57e7 2015-11-11T10:54:41 tests: implement worktree helpers
Patrick Steinhardt 8acc3b16 2015-11-10T15:53:09 tests: add merge-conflict branch for testrepo Add a new branch that causes a merge conflict to `testrepo` so that we are able to test merging in worktrees.
Patrick Steinhardt e5a620de 2015-11-09T17:00:41 tests: add submodule worktree test data Create worktrees for submodule repositories. The worktrees are created for the parent repository (e.g. the one containing submodules) and for the contained child repository.

Christopher Bargren 5f3276c7 2017-02-07T16:33:28 Add support for lowercase proxy environment variables curl supports HTTPS_PROXY in addition to https_proxy (and their http counterparts). This change ensures parity with curl's behavior.
Patrick Steinhardt 3428a523 2017-02-08T12:02:32 tests: repo: assert discovery starting at Win32 roots finishes As of recently, we failed to correctly discover repositories at a Win32 system root. Instead of aborting the upwards-traversal of the file system, we were looping infinitely when traversal started at either a Win32 drive prefix ("C:/") or a network path ("//somehost"). The issue has been fixed, so add a test to catch regressions.
Patrick Steinhardt 9e8d75c7 2017-02-08T11:41:10 path: ensure dirname on Win32 prefix always has a trailing '/' When calling `git_path_dirname_r` on a Win32 prefix, e.g. a drive or network share prefix, we always want to return the trailing '/'. This does not work currently when passing in a path like 'C:', where the '/' would not be appended correctly. Fix this by appending a '/' if we try to normalize a Win32 prefix and there is no trailing '/'.
Patrick Steinhardt 5d59520c 2017-02-07T20:30:11 path: get correct dirname for Windows root Getting the dirname of a filesystem root should return the filesystem root itself. E.g. the dirname of "/" is always "/". On Windows, we emulate this behavior and as such, we should return e.g. "C:/" if calling dirname on "C:/". But we currently fail to do so and instead return ".", as we do not check if we actually have a Windows prefix before stripping off the last directory component. Fix this by calling out to `win32_prefix_length` immediately after stripping trailing slashes, returning early if we have a prefix.
Patrick Steinhardt d8c06070 2017-02-07T20:21:38 path: extract `win32_path_prefix` function Extract code which determines if a path is at a Windows system's root. This incluses drive prefixes (e.g. "C:\") as well as network computer names (e.g. "//computername/").

Edward Thomson 104a1b0b 2017-02-02T17:21:23 Merge pull request #4105 from pks-t/pks/vector-reverse-overflow Vector reverse overflow
Patrick Steinhardt f47db3c7 2017-02-02T16:02:57 vector: do not reverse a vector if it is empty The code reversing a vector initially determines the rear-pointer by simply subtracting 1 from the vector's length. Obviously, this fails if the vector is empty, in which case we have an integer overflow. Fix the issue by returning early if the vector is empty.

Brock Peabody 673dff88 2016-11-23T18:32:55 Skip submodule head/index update when caching. `git_submodule_status` is very slow, bottlenecked on `git_repository_head_tree`, which it uses through `submodule_update_head`. If the user has requested submodule caching, assume that they want this status cached too and skip it. Signed-off-by: David Turner <dturner@twosigma.com>
Brock Peabody 4d99c4cf 2016-11-23T18:32:48 Allow for caching of submodules. Added `git_repository_submodule_cache_all` to initialze a cache of submodules on the repository so that operations looking up N submodules are O(N) and not O(N^2). 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. I changed it to process the `.gitmodules` file once, into a map. Signed-off-by: David Turner <dturner@twosigma.com>
