[jira] [Resolved] (OAK-9765) Garbage Collection does not remove blobs file from the file system

["Marcel Reutegger (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/OAK-9765?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Marcel Reutegger resolved OAK-9765.
-----------------------------------
    Resolution: Invalid

AFAICS the test does not run compaction on the SegmentNodeStore. This means the blob is still reference by a segment even if the property has been deleted. The test needs to run a full compaction on the SegmentNodeStore before a blob garbage collection is triggered. Only then will the unused blob be removed.

> Using a NodeStore backed by a FileStore, with a blob store of type FileBlobStore:
>  # (having configured GC with estimation {_}disabled{_})
>  # a file is added as a blob
>  # then the node where the blob is references is _removed_
>  # then the GC is run
>  # expected behaviour: the node is no more accessible, _and_ no chunk of the blob is present on the file system
>  # actual behaviour: the node is no more accessible BUT all the chunks are still present on the file system
> Steps to reproduce: execute the (really tiny) main in [https://github.com/PiercarloSlavazza/oak-garbage-collection-test/] (instructions in the readme)
