How to remove tmp files uploaded by dvc add --out

dvc is supposed to clean that up when the operation is completed. I see that it’s a bug in add --out here:

src/dvc_data/hashfile/build.py

4ee77349a


      
              from_path: "AnyFSPath",
              fs: "FileSystem",
              odb: "HashFileDB",
              upload_odb: "ObjectDB",
              callback: Optional[Callback] = None,
          ) -> tuple[Meta, HashFile]:
              from dvc_objects.fs.utils import tmp_fname
          
              from .hash import HashStreamFile
          
              tmp_info = upload_odb.fs.join(upload_odb.path, tmp_fname())
              with fs.open(from_path, mode="rb") as stream:
                  hashed_stream = HashStreamFile(stream)
                  size = fs.size(from_path)
                  cb = callback or TqdmCallback(
                      desc=upload_odb.fs.name(from_path),
                      bytes=True,
                      size=size,
                  )
                  with cb:
                      fileobj = cast("BinaryIO", hashed_stream)

I’ll try to fix it soon. (I’d encourage you to open an issue in Create new issue - iterative/dvc though).

It’s safe to remove those files. Unfortunately, dvc gc command does not clean those up.
