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.
* test: clean up test dirs
Closes#1770. Partially does #1888.
* dvc: close anything opened
* test: finalize git repo explicitly to remove test dir later
This was previously an issue on Windows.
* test: remove never used copy of load_stage_file()
* dvc: save comments and custom formatting in stage files
* Add a couple of TODOs
* test: test repro doesn't clear comments and formatting in .dvc
As part of this I started writing pytest-like tests and added commonly
used fixtures.
* test: simplify and prettify dvc formatting retained test
Also test that line comments after md5 fields are retained.
* test: fix tests
* dvc: fix stage and metrics opens not closed
* dvc: always use utf-8 in stage files
It used to encode in system default encoding. Not sure if PyYAML was
handling this silently or we were just lucky all the way.
* test: unit test apply_diff()
* test: remove TODOs and ASK
* dvc: polish dvc-formatting PR
* dvc: move stage load/dump utils to a new stage utils file
* dvc: clean up apply_diff()
* test: test stage md5 ignores comments
* test: remove pytests starting marker
