    • str: introduce `git_str` for internal, `git_buf` is external · f0e693b1
      libgit2 has two distinct requirements that were previously solved by
      `git_buf`.  We require:
      
      1. A general purpose string class that provides a number of utility APIs
         for manipulating data (eg, concatenating, truncating, etc).
      2. A structure that we can use to return strings to callers that they
         can take ownership of.
      
      By using a single class (`git_buf`) for both of these purposes, we have
      confused the API to the point that refactorings are difficult and
      reasoning about correctness is also difficult.
      
      Move the utility class `git_buf` to be called `git_str`: this represents
      its general purpose, as an internal string buffer class.  The name also
      is an homage to Junio Hamano ("gitstr").
      
      The public API remains `git_buf`, and has a much smaller footprint.  It
      is generally only used as an "out" param with strict requirements that
      follow the documentation.  (Exceptions exist for some legacy APIs to
      avoid breaking callers unnecessarily.)
      
      Utility functions exist to convert a user-specified `git_buf` to a
      `git_str` so that we can call internal functions, then converting it
      back again.

    • repository: make check if repo is a worktree more strict · 2696c5c3
      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.
