protocol/client: Register a timer(grace-timer) conditionally.

2012-03-10T13:27:56+00:00

A grace timer is registered on a disconnect, but a reconnect timer sends a
connect request after every 3sec and if the server is down, the client protocol
receives disconnect and a grace timer will be registered which on timeout will
increase the lk-version value. Its enough to register the grace timer once after
the disconnect and later just ignore other psuedo disconnects.

protocol/client: Added lk_ctx info in fdctx dump

2012-03-07T18:17:41+00:00

- Added a brief explanation as to why we can't use gf_log
  when in statedump.

- Removed gf_log messages from client_priv_dump since
  it can cause a 'deadlock' - See statedump.c for explanation

- Added try-lock based accessors for fd_lk_list for dump purposes.

fops/removexattr: prevent users from removing glusterfs xattrs

2012-03-05T17:17:47+00:00

* Each xlator prevents the user from removing xlator-specific
  xattrs like trusted.gfid by handling it in respective removexattr
  functions.

* For xlators which did not define remove and fremovexattr,
  the functions have been implemented with appropriate checks.

protocol/client: Calling GF_FREE on memory allocated via GF_CALLOC.

2012-03-01T18:02:42+00:00

This is a temporary fix. A clean fix would be to allocate memory using mem_get0
and free via mem_put.

transport/socket: configuring tcp window-size

2012-02-29T10:10:44+00:00

Till now, send and recieve buffer window sizes for sockets
were set to a default glusterfs-specific value.
Linux's default window sizes have been found to be better
w.r.t performance, and hence, no more setting it to any
default value.

However, if one wishes, there's the new configuration option:
   network.tcp-window-size 
which takes a size value (int or human readable) and will set
the window size of sockets for both clients and servers.
Nfs clients will also be updated with the same.
