glusterd-syncop: Fix unlocking and collating errors

2013-06-04T20:27:35+00:00

* Only those peers which were locked need to be unlocked.
* Fix location of collating errors in callbacks. The callback functions
  could miss collating errors if there was an rpc error.

Revert "glusterd: Fix spurious wakeups in glusterd syncops"

2013-05-05T04:35:52+00:00

This reverts commit efa154bb0a4cac34d5a9610ec25d38eebe495f22.

-- Following is Avati's analysis (edited) from gerrit --
The claim of the patch (being reverted) is that it in some cases cbkfn
is missed.  This is wrong analysis. cbk_fn is _always_ called. The patch
treats ret > 0 as a "missed cbk". ret > 0 only means socket submission
was not complete, and is queued to submit asynchronously when POLLOUT is
raised.  This is sufficient to guarantee that cbkfn is going to be
called (either the socket errors or submission succeeds and reply
eventually arrives).

This commit also removes spurious barrier_wake(s).

call backs are guaranteed to be called even if the transport is
disconnected. This means, a 'wake' would be called if rpc_clnt_submit is
called.  Also, we count both successful and failed operations in a
particular batch of operations for the synctask_barrier_wait.  So,
calling synctask_barrier_wake on failure of rpc_clnt_submit (say, due to
network failure) would result in a spurious wake.

glusterd: Fixed spurious wakeups in glusterd syncops

2013-04-12T07:22:28+00:00

glusterd syncops perform a barrier_wake whenever rpc_clnt_submit returned -1.
This is based on the wrong assumption that the cbkfn wasn't called.
This would result in one more wakeup than there ought to be.

glusterd: fix bugs of syncop for operations

2012-03-22T11:19:18+00:00

* free the stack created for synctask
* use different key than 'operation' in dictionary as thats being used
  already by other glusterd operations
* send proper frame to 'rpc_clnt_submit()' API, as it gets used
  internally
* also make sure to destroy the above frame in all _cbk()
* move everything specific to synctask into one file, so it is easy to
  maintain
