Marking as ready for review given that the code is pretty much complete. Once the build passes, we can review and merge this change.

Remaining developments:

• convert the code dealing with yielded exceptions from readfile(), now that the function can raise them.
• rename exception messages (ENOENT goes into the cs3 library, EXCL_ERROR gets replaced from the library)
• get rid of versioninv

Following cs3org/cs3-python-client#8 we now pass the whole test suite:

$ pytest-3

Therefore this is ready to review.

@micbar a heads-up about a larger-than-usual change.

Thanks. We are not using this Wopiserver anymore. We have now a fully integrated and tested solution in https://github.com/owncloud/ocis/tree/master/services/collaboration

In that solution we are using the go-cs3 bindings like we also use in reva.

Thanks. We are not using this Wopiserver anymore.

Thanks for the notice, I suspected that indeed. Will be interesting to see how that service evolves and if we could converge too, though from memory the ocis-integrated solution would not include some (non-strictly-wopi) features we use at CERN.
