Hi,

I'm currently working on a Pyramid/ZODB based application using RelStorage (release 2.1.0, with Python 3.5 and a PostgreSQL database).

Blobs are stored on the filesystem using a shared blobs directory.

Here is my configuration file:

%import relstorage

<zodb>
<relstorage>
keep-history false
blob-dir /var/local/env/website/var/db/blobs
shared-blob-dir yes
<postgresql>
dsn host='xxx' port='5432' dbname='xxx' user='xxx' password='xxx'
</postgresql>
</relstorage>
cache-size 100000
</zodb>

Storage is configured without keeping history, but blobs are not removed from filesystem when an object is deleted, or when packing the database!

So my question is simple: how can I remove unused blobs from filesystem?

Best regards,

Thierry
