Revision 428edade4e6c70e5b51fcd4188d944fbb744d84c authored by David Howells on 11 May 2018, 23:28:58 UTC, committed by David Howells on 14 May 2018, 14:15:19 UTC
The handling of CB.CallBack messages sent by the fileserver to the client
is broken in that they are currently being processed after the reply has
been transmitted.
This is not what the fileserver expects, however. It holds up change
visibility until the reply comes so as to maintain cache coherency, and so
expects the client to have to refetch the state on the affected files.
Fix CB.CallBack handling to perform the callback break before sending the
reply.
The fileserver is free to hold up status fetches issued by other threads on
the same client that occur in reponse to the callback until any pending
changes have been committed.
