glusterfs.git/rpc, branch v3.3.0qa13

Second round of warning suppression.

2011-09-29T18:52:30+00:00

Used a #pragma to kill ~170 in rpcgen code.  Added GF_UNUSED to deal with
a few more from macros elsewhere.  The remainder are function return values
(mostly context and dict calls) that really should be checked.  Those would
be harder to fix without real understanding of the code where they occur,
so they remain as reminders.

(Patchset 2: deal with older gcc that doesn't handle #pragma GCC diagnostic)

(Patchset 3: fix include paths in generated files)

(Patchset 4: keep up with trunk, squash 9 new warnings)

(Patchset 5: six more, all in AFR)

cli : new volume statedump command

2011-09-27T13:45:10+00:00

Changes:
        1. Add a new 'volume statedump' command, that performs statedumps of
        all the bricks in the volume and saves them in a specified location.
        2. Add new server option 'server.statedump-path'.
        3. Remove multiple function definitions in glusterd.h

Statedump Information:

The 'volume statedump' command performs statedumps on all the bricks in
a given volume. The syntax of the command is,
        gluster volume statedump  [type]......

Types include,
        * all
        * mem
        * iobuf
        * callpool
        * priv
        * fd
        * inode
Defaults to 'all' when no type is specified.

The statedump files are created by default in /tmp directory of the
server on which the bricks are present.
This path can be changed by setting the 'server.statedump-path' option.

The statedump files will be named as,
        ..dump

rpc: fix wrong wiping of state machine's state

2011-09-25T13:15:12+00:00

The macro __socket_proto_read() is used to read one sub-header in a fragment
after another. It also has to 'get out' of the state machine's
switch/case construct in two situations -

a) finished reading the full header

b) after a partial read, (and return in the same state at next pollin)

The 'reset' of the state should happen only after a full read of the header
and not if there was a partial read of the header.

rpc: No timeouts for lock fops.

2011-09-23T13:11:32+00:00

As of today, all fops bail out after 30 mins by default. This is not desirable
with lock fops since it could be 'rightfully blocked' for a really long time.
But the client would assume that the lock fop has 'expired' after 30 mins and
clean up its references to the locks.  Later when the locks xlator decides to
grant it, we are left with an orphan (stale) lock .

This fix exempts lock fops from timeouts. Only on network disruptions both
client and server decide to 'clean up' the locks held.
