[libvirt] PATCH: Pass 'remote_error' object to RPC handlers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In the libvirtd daemon, remote.c file the current RPC handlers have 
a return value contract saying

   0 - success
  -1 - failure in libvirt call, no error returned
  -2 - failure in dispatch process, error already serialized & sent

While this isn't a problem for the code as it stands today, for the thread
support I want to be able to avoid the dispatch handlers having to touch
the 'struct qemud_client' object in normal usage.  Allowing the RPC 
handlers to directly serialize & send the error makes this impossible
because it requires access to the client object.

So this patch changes the way the RPC handlers deal with errors. The
RPC handler API changes from

  typedef int (*dispatch_fn) (struct qemud_server *server,
                              struct qemud_client *client,
                              dispatch_args *args,
                              dispatch_ret *ret);

To

  typedef int (*dispatch_fn) (struct qemud_server *server,
                              struct qemud_client *client,
                              remote_error *err,
                              dispatch_args *args,
                              dispatch_ret *ret);

Note, the addition of a 'remote_error *err' argument. Whenever an error
occurs during the dispatch process, the RPC handler must populate this
'remote_error *err' object with the error details. This rule applies
whether its a libvirt error, or a dispatch process error, so there is
no longer any need to have separate -1 or -2 return values, a simple
-1 or 0 return value suffices.

This is a rather ugly / unreadable patch I'm afraid - its worth also
looking at the complete before & after code to understand it better.
