Ceph

ceph::buffer::list::iterator_impl<false>::advance(int) was changed to buffer::list::iterator_impl<is_const>::advance(ssize_t o) along with other methods, like void buffer::list::iterator_impl<is_const>::seek(unsigned o), which was changed to void buffer::list::iterator_impl<is_const>::seek(size_t o), in https://github.com/ceph/ceph/pull/9395 as the fix for #16010.

see the discussion in the https://github.com/ceph/ceph/pull/9395, the ABI changes are expected. and we do not plan to fix it.

the buffer::list::const_iterator was introduced in infernalis, and the commit which exposed it via librados was 16bc3e59325d4057d36cd63a57111ab36fbc50fd), and the change breaking the ABI is in master, and hence will be in kraken.

will look at it closer to see if this is really expected, if yes, how to disable this test.

the commit of 6c645780dd485770abd54e3585975098fd808354 was merged after infernalis,
it excludes iterator_impl symbols in the librados. and this commit exists in jewel and master.

and in 16bc3e59325d4057d36cd63a57111ab36fbc50fd export these symbols again. but 16bc3e59325d4057d36cd63a57111ab36fbc50fd only exists in master.

so, to fix the issue here, we need to backport 16bc3e59325d4057d36cd63a57111ab36fbc50fd to jewel

rescheduling another run at http://pulpito.ceph.com/kchai-2016-08-02_07:44:12-upgrade-wip-16507-jewel---basic-mira/

test failure is tracked by #16898

Nathan, thanks for updating this ticket and creating a backport ticket for this issue!
