Each of the ypclnt functions does a _yp_dobind() when it starts and then a _yp_unbind() when it finishes. This is not strictly necessary and it wastes cycles: it means we do a new clnt_create() and clnt_destroy() for each yp_whatever() call. In fact, you can do multiple clnt_call()s using a single RPC client handle returned by clnt_create(). Ideally we only have to create a handle to ypserv once (the first time we call a ypclnt function) and then destroy it and rebind only if a call to ypserv fails. - Modify _yp_dobind() so that it only creates a new RPC client handle when establishing a new binding or when one of the ypclnt calls invalidates an existing binding and calls _yp_dobind() to establish a new one. - Modify the various ypclnt functions to only call _yp_unbind() if a call to ypserv fails. |
