core: fix all the iobuf related refs and unrefs

2012-03-29T14:54:34+00:00

reviewed the code against all the possible places where
iobuf/iobref ref unref are present, and hopefully fixed most of
the issues around memory leaks with respect to iobuf

protocol/client: Set grace_timer_needed flag to false on a disconnect.

2012-03-28T09:59:34+00:00

A grace timer is registered on a disconnect, but a reconnect timer sends a
connect request after every 3sec and if the server is down, the client protocol
receives disconnect and a grace timer will be registered which on timeout will
increase the lk-version value. Its enough to register the grace timer once after
the first disconnect and later just ignore other psuedo disconnects until the
next successful reconnect.

core: adding extra data for fops

2012-03-22T23:40:27+00:00

with this change, the xlator APIs will have a dictionary as extra
argument, which is passed between all the layers. This can be
utilized for overloading in some of the operations.

rpc-clnt: separate out connection_cleanup() from destroy()

2012-03-19T16:14:40+00:00

noticed that there are possibilities where one would like to do a
connection_cleanup() before destroying a RPC connection itself, also
current code is such that, rpc_clnt_connection_cleanup() does
rpc_clnt_ref() and unref(), creating a race window/double unref
possibilities in the code.

by separating out the functions, this race window/double fault can be
prevented.

protocol/server: Handle server send reply failure gracefully.

2012-03-19T15:11:43+00:00

Server send reply failure should not call server connection cleanup because
if a reconnection happens with in the grace-timeout the connection object is
reused. We must cleanup only on grace-timeout.
