Bug 1055 - Access and query shared master GLContext in a deterministic fashion ; Don't use arbitrary shared context as 'master'.
GLContext* passes the shared-master to GLContextShareSet, which only creates a sets of shared contexts without differentiating the master context. GLContext*'s shared-slave attempts to lock the realized shared-master's surface at creation. Currently only an arbitrary shared context is selected due to the missing 'master' identity. The arbitrary shared context's surface is locked and its shared context handle used to create the slave context. Lacking of using the user given shared-master can lead to deadlock situations - and locking a 'wrong' surface. +++ The patch: - Allows query the user given shared-master! - Use the user given shared-master for locking and it's context handle for the slave's creation. - The shared-context mapping maps each shared-master to a shared-slave within one shared-context-set, allowing deterministic and individual shared-master queries.
