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.

syncop: Make syntask scalable

2012-03-10T06:19:32+00:00

At the moment, synctask uses task->frame to perform
all the syncops, this will lead to high-memory usage if the task
crawls millions of directories. i.e millions of STACK_WINDS/UNWINDS.
To prevent this, in each task a new stack is created to perform
the fops which is reset after every syncop.

libglusterfs/fd: fixed fd_anonymous() leak

2012-03-07T18:39:50+00:00

fd was getting leaked whenever there was a overlapping operations,
which caused memory leak, and process fd leaks, which made most of
the operations on NFS mount of a replicate volume not work. With
the fix, things are back to normal.

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.

mempool: add more counters to understand the usage scenarios properly

2012-02-27T10:18:35+00:00

current design of mempool is to fallback to standard calloc/free if
all the buffers in pool are exhausted. Understanding more about those
numbers will help us to tune mempool parameters properly over time.

libglusterfs: fix GF_FREE

2012-02-27T10:15:51+00:00

Argument-taking macros should be possible to use with
same syntax that of C functions. In particular (assuming
FOO is a single-argument macro),

  FOO(bar)

should break and

  if (cond)
    FOO(bar);
  else
    baz();

should compile.

Introduce new extended attribute: node-uuid

2012-02-23T07:19:44+00:00

Request for trusted.glusterfs.node-uuid returns pathinfo
like string but containing the UUID of glusterd instead
of the backend path for the requested file. This info
is benificial for tasks like parallel rebalance that will
make use of the UUID for data locality.
