protocol/client : Refactoring functions

2016-05-01T00:21:07+00:00

These changes are made to accommodate compound fops.
The new functions that are added pack
the arguments required to perform the fops.
These will be used both by normal fops and compound ones.

dht/afr/client/posix: Fail mkdir without gfid-req

2016-04-29T13:57:39+00:00

Do not allow directory creations without gfids as
after the directories are created, operations
on them fail anyway. So it is better to fail mkdir.

protocol client/server: Fix client-server handshake

2016-03-10T17:24:33+00:00

Problem:
Currently on a successful connection between protocol
server and client, the protocol client initiates a
CHILD_UP event in the client stack. At this point in
time, only the connection between server and client is
established, and there is no guarantee that the server
side stack is ready to serve requests.

It works fine now, as most server side translators are
not dependent on any other factors, before being able
to serve requests today and hence they are up by the time
the client stack translators receive the CHILD_UP (initiated
by client handshake).

The gap here is exposed when certain server side translators
like NSR-Server for example, have a couple of protocol clients
as their child(connecting them to other bricks), and they
can't really serve requests till a quorum of their children are
up. Hence these translators should defer sending CHILD_UP
till they have enough children up, and the same needs to be
propagated to the client stack translators.

Fix:
Maintain a child_up variable in both the protocol client
and protocol server translators. The protocol server should
update this value based on the CHILD_UP and CHILD_DOWN
events it receives from the translators below it. On receiving
such an event it should forward that event to the client.
The protocol client on receiving such an event should forward
it up the client stack, thereby letting the client translators
correctly know that the server is up and ready to serve.

The clients connecting later(long after a server has initialized
and processed it's CHILD_UP events), will receive a child_up status
as part of the handshake, and based on the status of the server's
child_up, can either propagate a CHILD_UP event or defer it.
