* gc: make it safer by only activating by use of certain flags
Previous plain `gc` is now not supported. The same behavior can be trigger by
`gc -w` or `gc --workspace`. When `--all-{tags, commits, branches}` are
specified, it will work as if `-w` is also specified (same as before).
* tests: adjust gc to use workspace on test_repro
* dvc: refactor config
Advantages:
- read like a dict
- modify as a dict for testing or manipulation purposes
- wrap modifications into context manager to save them:
with config.edit("local") as conf:
conf["core"]["remote"] = "new-default"
Design decisions:
- dropped string constants
- remote sections are parsed into a simple subdict upon load
- remote config schema is now defined by url scheme
- relative paths are handled transparently upon load/save
- user config and remote manipulations are moved to commands
- same dev manipulations are done by simply modifying a config dict
* test: do not set cache.type for remotes that doesn't support it
* dvc: fix windows absolute paths validation in config
* test: fix windows separate drive test
* dvc: stylistic fixes in config
Make `Repo.checkout` accept a list of targets, instead of having to feed
it targets one-by-one. This allows us to properly handle checkout
errors.
Fixes#2580
Imagine the scenario of shared cache. To set it up, user would do:
```
dvc config cache.dir /path
dvc config cache.shared group
```
Now, when he runs any dvc operation that involves the Repo instance,
RemoteLOCAL will also be initialized and it will currently auto-create
the directory with a regular `os.mkdir`, which is not using group
permissions. To solve that, we can't simply use `self.makdirs` instead,
as it will cause same issues if you run any dvc command before
`dvc config cache.shared group`. So what we should do is create
directories on demand, instead of creating it in advance, same as we do
in other remotes.
The change itself is pretty trivial and involved removing that `mkdir`
line, adjusting tests to not rely on cache dir existence and also
adjusting `dvc version` to not rely on cache directory existance.
Fixes#2563
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.
