keep_local does not keep remote files locally

[Hugovdberg]

Snakemake version

8.10.8

Describe the bug

Local copies of remote files are deleted after a rule finishes, even when keep_local is True. If I provide keep_local on the provider level the .snakemake/storage folder is deleted entirely. If I provide the option on the file level then the entire folder structure is kept in place, but the files are still removed.

Logs

Minimal example

storage http:
    provider="http",
    keep_local=True, # provider level

rule:
    input:
        storage.http('http://www.wettelijkerente.net/wettelijkerente2.csv', keep_local=True) # file level
    output:
        'results/output.txt'
    run:
        import shutil
        shutil.copy(input[0], output[0])
