[Touch-packages] [Bug 1434400] Re: [regression] Client ABI 8 broken in 0.13 series
Hmm, OK. Seems the test only fails locally between r2407 and 2408. But on the wider scale between releases we've maintained compatibility from 0.11/0.12 to dev r2408. It seems the problem was fixed in r2408 relative to previous releases. However revisions after 0.12.0 and prior to r2408 had ABI breaks. And yes, it does indeed seem that we've maintained ABI compatibility by virtue of having libmircommon.so.3 and libmircommon.so.4 loadable in the same client process simultaneously. Scary, but seems to work. ** Changed in: mir Status: In Progress => Incomplete ** Changed in: mir (Ubuntu) Status: New => Incomplete ** Changed in: mir Milestone: 0.13.0 => None -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1434400 Title: [regression] Client ABI 8 broken in 0.13 series Status in Mir: Incomplete Status in mir package in Ubuntu: Incomplete Bug description: I've just done a little sanity testing of our client ABI changes and found we've broken the client 8 ABI at least once, maybe twice in series 0.13.
