             Bug #: 48979
           Summary: Protocol: Atomicity
    Classification: Unclassified
           Product: Wayland
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: wayland
        AssignedTo: wayland-bugs at lists.freedesktop.org
        ReportedBy: darxus at chaosreigns.com
            Blocks: 48976


Currently a lot of the atomicity in Wayland relies on how we batch up all
requests in a protocol buffer and only flushes in the "blockhandler" in the
client.  Consensus was that we need something more reliable and explicit.  The
suggestion is that we make surface.attach a synchronization point such that
everything before that is batched and applied atomically when the
surface.attach request comes in.  For cases where we need atomicity beyond a
surface.attach, we can add an atomic grouping mechanism, that can group
together multiple surface.attach requests into a bigger atomic change.  To be
researched a bit.
