* Rework GIT_DIRREMOVAL values to GIT_RMDIR flags, allowing
combinations of flags
* Add GIT_RMDIR_EMPTY_PARENTS flag to remove parent dirs that
are left empty after removal
* Add GIT_MKDIR_VERIFY_DIR to give an error if item is a file,
not a dir (previously an EEXISTS error was ignored, even for
files) and enable this flag for git_futils_mkpath2file call
* Improve accuracy of error messages from git_futils_mkdir
This started as a complex new test for checkout going through the
"typechanges" test repository, but that revealed numerous issues
with checkout, including:
* complete failure with submodules
* failure to create blobs with exec bits
* problems when replacing a tree with a blob because the tree
"example/" sorts after the blob "example" so the delete was
being processed after the single file blob was created
This fixes most of those problems and includes a number of other
minor changes that made it easier to do that, including improving
the TYPECHANGE support in diff/status, etc.
Add a new command `git_repository_open_ext` with extended options
that control how searching for a repository will be done. The
existing `git_repository_open` and `git_repository_discover` are
reimplemented on top of it. We may want to change the default
behavior of `git_repository_open` but this commit does not do that.
Improve support for "gitdir" files where the work dir is separate
from the repo and support for the "separate-git-dir" config. Also,
add support for opening repos created with `git-new-workdir` script
(although I have only confirmed that they can be opened, not that
all functions work correctly).
There are also a few minor changes that came up:
- Fix `git_path_prettify` to allow in-place prettifying.
- Fix `git_path_root` to support backslashes on Win32. This fix
should help many repo open/discover scenarios - it is the one
function called when opening before prettifying the path.
- Tweak `git_config_get_string` to set the "out" pointer to NULL
if the config value is not found. Allows some other cleanup.
- Fix a couple places that should have been calling
`git_repository_config__weakptr` and were not.
- Fix `cl_git_sandbox_init` clar helper to support bare repos.
This fixes an issue which was detected while using one of the libgit2 bindings [0]. The lack of the trailing forward slash led the name of references returned by git_reference_listall() to be prefixed with a forward slash.
