Swift3 Compatibilities

[chmouel]

Moving https://bugs.launchpad.net/swift/+bug/973516 to here:

I ran the s3 test suites :

https://github.com/ceph/s3-tests

against swift + s3 (with keystone auth but this should be exactly the same for the other auth).

This is the results :

Ran 250 tests in 129.963s
FAILED (errors=61, failures=62)

and this is the full output :

there is quite a bit to fix but at least it's a start to document the incompatibilities.

Ran s3-tests on devstack today,

Ran 256 tests in 549.933s

FAILED (errors=61, failures=44)

From what I can tell, all of the content-length issues are derived from WSGI - basically the validation of the content-length header in eventlet/wsgi.py raises a ValueError exception for bad content lengths, when we need it to return HTTP_BAD_REQUEST

Example:

Great, can I put the link somewhere (Swift3 website, probably)?

Thanks!

of course :)
