[Libvirt-ci] Passed: libvirt/libvirt#2121 (master - 1c56005)

Build Update for libvirt/libvirt ------------------------------------- Build: #2121 Status: Passed Duration: 45 mins and 18 secs Commit: 1c56005 (master) Author: Eric Blake Message: object: Add sanity check on correct parent class Checking that the derived class is larger than the requested parent class saves us from some obvious mistakes, but as written, it does not catch all the cases; in particular, it is easy to forget to update a VIR_CLASS_NEW when changing the 'parent' member from virObject to virObjectLockabale, but where the size checks don't catch that. Add a parameter for one more layer of sanity checking. It would be cool if we could get gcc to stringize typeof(parent) into the string name of that type, so that we could confirm that the precise parent class is in use rather than just a struct that happens to have the same size as the parent class. But sizeof checks are better than nothing. Note that I did NOT change the fact that we require derived classes to be larger (as the difference in size makes it easy to tell classes apart), which means that even if a derived class has no functionality to add (but rather exists for compiler-enforced type-safety), it must still include a dummy member. But I did fix the wording of the error message to match the code. Signed-off-by: Eric Blake <eblake(a)redhat.com&gt; Reviewed-by: Ján Tomko <jtomko(a)redhat.com&gt; Reviewed-by: Daniel P.
