| Doc Text: |
Cause:
Image registry purging process running over s3 storage was listing a directory twice, first as a directory and later as a file.
Consequence:
Purging was failing when parsing the path for the directory (received as file), causing an invalid memory access (panic)
Fix:
Updated s3 driver to avoid listing a directory twice during path walk.
Result:
By avoiding listing a directory as a file allowed the image purging process to finish successfully.

Verified on 4.6.0-0.nightly-2020-09-21-230455: 1. set up s3fs locally https://github.com/s3fs-fuse/s3fs-fuse/ and mount s3 bucket 2. cd /mnt/s3bucket/docker/registry/v2/repositories;mkdir fakeimage 3. purge load happens and no panic appears.
