import: fetch downloads data to default cache dir #10794
Description
Bug Report
import: fetch downloads data to default cache and ignores cache config
Description
When fetching data that is imported with import-url, the data is first downloaded to the default cache directory before it is moved to the cache directory set in the configuration. This is problematic when a large dataset is imported.
The code that defines the path for the fs cache uses the default cache directory instead of the one set in the configuration.
# dvc/cachemgr.py
@property
def fs_cache(self):
"""Filesystem-based cache.
Currently used as a temporary location to download files that we don't
yet have a regular oid (e.g. md5) for.
"""
from dvc_data.index import FileStorage
return FileStorage(
key=(),
fs=self.local.fs,
path=self.local.fs.join(self.default_local_cache_dir, self.FS_DIR),
)Reproduce
dvc import-url --no-download https://data.dvc.org/get-started/data.xmldvc fetch data.xml.dvc
Expected
The data is downloaded to CACHE_DIR/fs where CACHE_DIR is the one set in the configuration.
