a22f19e6	2018-02-09T10:38:11	worktree: add ability to create worktree with pre-existing branch Currently, we always create a new branch after the new worktree's name when creating a worktree. In some workflows, though, the caller may want to check out an already existing reference instead of creating a new one, which is impossible to do right now. Add a new option `ref` to the options structure for adding worktrees. In case it is set, a branch and not already checked out by another worktree, we will re-use this reference instead of creating a new one.
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.
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.
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.
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.
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.

6f6dd17c	2016-11-08T12:13:59	worktree: test creating and opening submodule worktrees
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.
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.
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.
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.
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.
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.
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.
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.

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.
