* Move path_get outside of sys module
* Add implementation of readlinkat
* Clean up path_open; use OpenOptions as much as possible
* Enable close_preopen test
* Implement path_create_directory; fix path_open
* Refactor path concatenation onto a descriptor
* Implement path_remove_directory
* Implement path_unlink_file
* Rewrite path_open using specific access mask
* Fix error mapping when unlinking file
* Fix readlinkat to pass nofollow_errors testcase
* Clean up winerror to WASI conversion
* Spoof creating dangling symlinks on windows (hacky!)
* Add positive testcase for readlink
* Implement path_readlink (for nonzero buffers for now)
* Clean up
* Add Symlink struct immitating *nix symlink
* Fix path_readlink
* Augment interesting_paths testcase with trailing slashes example
* Encapsulate path_get return value as PathGet struct
* Remove dangling symlink emulation
* Extract dangling symlinks into its own testcase
This way, we can re-enable nofollow_errors testcase
on Windows also.
