license: dual license under GPLV2 and LGPLV3+

2012-05-11T05:06:16+00:00

Note that the license was not changed in any of the following:
	.../argp-standalone/...
        .../booster/...
        .../cli/...
        .../contrib/...
        .../extras/...

        .../glusterfs-hadoop/...
        .../mod_clusterfs/...
        .../scheduler/...
        .../swift/...

The license was not changed in any of the non-building xlators. The
license was not changed in any of the xlators that seemed — to me — to
be clearly server-side only, e.g. protocol/server

Note too that copyright was changed along with the license; I did
not change the copyright in files where the license did not change.

iobuf: option to provide larger size of buffers

provide an option to failover to standard allocation if iobuf of
required size doesn't exists. this can be achieved by keeping an
arena dedicated for all the out of boundary allocations.

libgluster: Fix counting, synctask state errors

2012-05-03T10:50:35+00:00

When a synctask is executed in synctask_switchto, if by the time
it goes to check the woken/sleep part a reply already comes and
__wake is called, already running task is going to be put in runq
this generates a false warning "re-running already running task".

If the reply does not come before the woken/sleep check, then the
running task is put in waitq which decrements env->runcount even
when the task is not in runq, this leads to -ve runcount everytime
a task goes from runq->switchto->waitq.

This patch fixes both of them by introducing a new state for the
task called SYNCTASK_SUSPEND just when the task is suspended before
yeild in SYNCOP.

libglusterfs/fd: use reallocated memory for intializing new graphs contexts

2012-05-01T17:20:42+00:00

While setting fd_ctx, if we have to scale the fd contexts, then we get the
xl_count of the new graph and reallocate the memory for contexts so that
it is suffecient for contexts of xlators of both new as well as old graph, and
then initialize the new graph xlator contexts. For that we are considering the
old pointer itself, instead of using newly reallocated pointer.

Since while migrating fds to new graph we retain the same fd object,
we might run out of slots for new keys in fd->_ctx after some graph
switches.

Event_notify can be used by others to communicate with glusterd.
A cbk event is also added for future use.

req has a op, and dict.
rsp has op_ret, op_errno, and dict.

With this, rebalance process can update the status before
