The rclone backend wrote each object straight to its key, so killing an
upload to a local or sftp remote left a truncated object there. The next
backup found the key, skipped the upload and recorded a snapshot that
could not be restored.
On every remote with a server-side move, an object is now written under
a name ending in `.partial` and moved onto its key; listings skip such
names. Rclone's own copy also requires the remote's PartialUploads flag;
this does not, because hdfs shows a file while it is written without
setting it. Remotes without a move are written in place, as the README
now says.
Model: opus-5-5
internal/storage, the package that parses store URLs and selects the backend, had no tests.
Adds table-driven tests for URL parsing (each scheme, query parameters, malformed input, unknown scheme, backend type chosen); one shared conformance suite for the Storer interface, run against the file backend in a temp directory and the s3 backend on the in-process harness internal/s3 already uses, so a new backend inherits it; and rclone construction and argument tests using its in-process local backend. A comment records that rclone data operations need a configured remote and are not unit-tested. No production code changed and no defect surfaced.
