- cloud remotes still default to using PathInfo's
- if path is not relpath from cwd or abspath, posix lstat() syscall runtime doubles (from calculating relpath from cwd)

There was a problem hiding this comment.
If path is not abspath or relpath from current working dir, posix lstat() syscall runtime doubles. PathInfo.__str__ uses relpath from cwd, but since cwd may change during runtime (like in some of our erepo tests), we can't cache relpath(self.cache_dir) and we don't want to compute it each time, so we just use abspath.

PR treeverse#3672 (6d8499e) extended `LocalRemote::_get_plans` to return one `checksums` too. As all of the args from `_get_plans` was passed down to `download()`, it recognized extra arg of checksum as `no_progress_bar` due to which it became True and stopped showing progress bar at all. Fix treeverse#3874

Should close #3635.
statusandLocalRemote.cache_exists)_process/upload/downloadpipeline has been left alone for now - in the event that we are pushing or pulling enough files that using PathInfo's becomes noticeably slow, the expectation is already going to be that the operation will be slow, given that we will be uploading/downloading a lot of data.
