parser: make the parser thread safe.

2013-09-07T00:54:10+00:00

The volfile parser thread safe by guarding the parsing phase
in a mutex. Thread safety becomes a problem when there are multiple
glfs_t objects created by gfapi and all of them potentially parse
the respective volfiles at the same time.

glusterfsd: Round robin DNS should not be relied upon with

config service availability for clients.

Backupvolfile server as it stands is slow and prone to errors
with mount script and its combination with RRDNS. Instead in
theory it should use all the available nodes in 'trusted pool'
by default (Right now we don't have a mechanism in place for
this)

Nevertheless this patch provides a scenario where a list of
volfile-server can be provided on command as shown below

-----------------------------------------------------------------
$ glusterfs -s server1 .. -s serverN --volfile-id= \
      
-----------------------------------------------------------------
                   OR
-----------------------------------------------------------------
$ mount -t glusterfs -obackup-volfile-servers=: \
      :...: :/ 
-----------------------------------------------------------------

Here ':' is used as a separator for mount script parsing

Now these will be remembered and recursively attempted for
fetching vol-file until exhausted. This would ensure that the
clients get 'volume' configs in a consistent manner avoiding the
need to poll through RRDNS.

synctask: minor enhancements

2013-08-28T22:52:24+00:00

- Enhance syncenv_new() to accept scaling parameters of syncproc.
  Previously the scaling parameters were hardcoded and decided at
  compile time.

- New API synctask_create() which returns the created synctask. This
  is similar to synctask_new which only returned the status of whether
  a synctask could be created or not.

  The meaning of NULL cbk in synctask_create() means the task is
  "joinable". Until synctask_join() is called on such a synctask,
  the task is not reaped and resources are not destroyed. The
  task would be in a zombie state after synctask_fn returns and
  before synctask_join() is called.

protocol/server: Relax lktable finodelk del_locker check

2013-08-18T00:21:46+00:00

Problem:
Client xlator issues finodelk using anon-fd when the fd is not
opened on the file. This can also happen between attempts to re-open
the file after client disconnects. It can so happen that lock is taken
using anon-fd and the file is now re-opened and unlock would come with
re-opened fd. This will lead to leak in lk-table entry, which also
holds reference to fd which leads to fd-leak on the brick.

Fix:
Don't check for fds to be equal for tracking finodelks.
Since inodelk is identified by (gfid, connection, lk-owner)
fd equality is not needed.
