[ENG-337] [OATHPIT] Throw ownCloud into the Oath Pit

[cslzchen]

Ticket

https://openscience.atlassian.net/browse/ENG-337

Purpose

Enable and update the ownCloud provider for aiohttp 3.

Changes

• WB .make_request() now supports WebDAV methods
  • aiohttp.ClientSession only has functions available for native HTTP methods. For WebDAV (a protocol that extends HTTP) ones, WB lets the ClientSession instance call _request() directly and then wraps the return object with aiohttp.client._RequestContextManager.

• WB client session now supports customized connector
  • For providers that use a customized connector such as owncloud, the new session is created (if no session is found in the event loop) with the given connector while an existing session simply ignores (and closes) the new connector. Given that the session is per loop for each instance, the existing session if found must already have a connector with qualified customizations.

• Use kwarg ssl= instead of verify_ssl= when initializing aiohttp.TCPConnecto
  • verify_ssl= has been deprecated and no longer takes any effect on setting the property _ssl of a TCPConnector instance. Use ssl= instead. For details see the following links.
  • https://github.com/aio-libs/aiohttp/blob/3.5/aiohttp/connector.py#L733
  • https://github.com/aio-libs/aiohttp/blob/3.5/aiohttp/client_reqrep.py#L152
  • https://github.com/aio-libs/aiohttp/blob/v0.18.4/aiohttp/connector.py#L402

Side effects

No

QA Notes

Here is a list of tests that I have done locally, all of which have passed. Extra notes and quirks are added under each list if there is any. In addition, tests are done for both non-root and root.

• Getting metadata for a file and folder

  • This is automatic when you list files and expand folders

• Downloading (20B, 1 MB, 11 MB, 88 MB, 264MB)

• Contiguous Uploading (20B, 1 MB, 11 MB, 88 MB, 264MB one-by-one and together)

  • Chunked upload: N / A

• DAZ (a folder containing five files of 20B, 1 MB, 11 MB, 88 MB, 264MB)

• Delete a file and a folder; delete multiple files and folders

• Folder creation and deletion

• Renaming files and folders

  • After renaming a folder or file (successfully), clicking on the renamed folder triggers the following error. Please see the video attachment in the ticket.

• Intra move and copy

  • ownCloud supports intra move / copy. My local tests includes moving file and folders between two ownCloud projects with the same ownCloud account.

• Inter move and copy

  • Between ownCloud and OSFStorage
  • Between ownCloud and another 3rd-party (S3 in this case)

• Comments persist with moves

• Revisions: N / A

• Project root is storage root vs. a subfolder

  • Not required but I still tested this since I have to create two projects (one with root and the other with subfolder) anyway for testing intra copy / move.

• Updating a file
