Replaced Path* dataclasses with PathInfo/URLInfo/CloudURLInfo, which
know how parse, serialize, stringify and join themselves. They also
provide useful accessors like part of an url or pathlib.Path like
.parent or .name.
Along the way two families of bugs where fixed and should never occur in
the future:
- paths not matched as strings anymore, e.g. using str.startswith()
- Output.path is eliminated as ambiguous
Both families might had caused undefined surprising behavior when local
and remote paths clash.
* Document dvc.scm.git::Git::_get_diff_trees and shorten commit hashes in dvc.scm.git::Git::get_diff_trees
* diff: Changes to dvc.scm.git so `dvc diff` outputs short SHAs
- Docstring for Git class constructor
- Renames self.git for self.repo throughout module (involves several test changes)
- Better doc and logical refactor in Git._get_diff_trees
- `dvc diff` now outputs short SHA strings (Git._get_diff_trees) - hard coded to 7 length str
(involves some test changes in tests/func/test_diff.py)
For #1902
* Undoes "Renames self.git for self.repo throughout module" introduced in 3d2dc83.
* diff: `dvc diff` uses code for `git rev_parse --short` instead of hard `[:7]` (for short commit hashes).
- Tests updated too.
Per https://github.com/iterative/dvc/pull/1906#discussion_r278510340
* tests: Reformatted with `black tests/func/test_diff.py`
* tests: Remove uneccessary `str()` casting form `dvc diff` tests (and reformat)
