[QA] files uploaded via s3cmd with a prefix are not seen by `occ file:scan`

[jnweiger]

Seen while testing files_external_s3-2.0.0-rc.1 with owncloud core 10.11.0-alpha.2

• Configure an external storage using a scality s3 server
  

---

• Check number of objects with occ file:scan --all

  +---------+-------+--------------+------------------+
  | Folders | Files | Elapsed time | Items per second |
  +---------+-------+--------------+------------------+
  | 24      | 31    | 00:00:01     | 56               |
  +---------+-------+--------------+------------------+
  
  

• Add a file to the bucket (without path prefix) s3cmd put /var/www/owncloud/data/owncloud.log s3://oc-external/
• Check number of objects with occ file:scan --all -- it is one more. OK

  +---------+-------+--------------+------------------+
  | Folders | Files | Elapsed time | Items per second |
  +---------+-------+--------------+------------------+
  | 24      | 32    | 00:00:01     | 54               |
  +---------+-------+--------------+------------------+
  
  

• Add a file to the bucket (with prefix) s3cmd put /var/www/owncloud/data/owncloud.log s3://oc-external/logs/oc.log
• Check number of objects with occ file:scan --all -- nothing changes. BAD

  +---------+-------+--------------+------------------+
  | Folders | Files | Elapsed time | Items per second |
  +---------+-------+--------------+------------------+
  | 24      | 32    | 00:00:01     | 49               |
  +---------+-------+--------------+------------------+
  
  

• Visit the external storage via owncloud. The /oc-bucket/logs folder does not appear. BAD

Workaround:

• Create the /oc-bucket/logs folder via owncloud.
  

---

• Examine contents of the logs folder. The oc.log file is there.
  

---

• Now also occ file:scan reports the new folder and the new file.

Note: other external storages, likes e.g. SFTP do not have this problem. It seems specific to s3.
