rpc: fix typo which refers glibc macro

2013-08-23T10:34:01+00:00

A typo which read MAX_AUTH_BYTES instead of GF_MAX_AUTH_BYTES was
picking the value 400 instead of the larger 2048. This causes
failures when number of aux group ids is a large number.

libglusterfs/client_t client_t implementation, phase 1

2013-07-30T05:22:21+00:00

Implementation of client_t

The feature page for client_t is at
http://www.gluster.org/community/documentation/index.php/Planning34/client_t

In addition to adding libglusterfs/client_t.[ch] it also extracts/moves
the locktable functionality from xlators/protocol/server to libglusterfs,
where it is used; thus it may now be shared by other xlators too.

This patch is large as it is. Hooking up the state dump is left to do
in phase 2 of this patch set.

(N.B. this change/patch-set supercedes previous change 3689, which was
corrupted during a rebase. That change will be abandoned.)

glusterd/cli changes for distributed geo-rep

2013-07-26T20:19:18+00:00

Commands:
gluster system:: execute gsec_create
gluster volume geo-rep   create [push-pem] [force]
gluster volume geo-rep   start [force]
gluster volume geo-rep   stop [force]
gluster volume geo-rep   delete
gluster volume geo-rep   config
gluster volume geo-rep   status

The geo-replication is distributed. The session will be created, and
gsyncd will be spawned on all relevant nodes, instead of only one
node.

geo-rep: Collecting status detail related data

Added persistent store for saving information about
TotalFilesSynced, TotalSyncTime, TotalBytesSynced

Changes in the status information in socket:
Existing(Ex):
FilesSynced=2;BytesSynced=2507;Uptime=00:26:01;

New(Ex):
FilesSynced=2;BytesSynced=2507;Uptime=00:26:01;SyncTime=0.69978;
TotalSyncTime=2.890044;TotalFilesSynced=6;TotalBytesSynced=143640;

Persistent details stored in
/var/lib/glusterd/geo-replication/${mastervol}/${eSlave}-detail.status

rpc: duplicate request cache for nfs

2013-06-21T17:33:49+00:00

Duplicate request cache provides a mechanism for detecting
duplicate rpc requests from clients. DRC caches replies
and on duplicate requests, sends the cached reply instead of
re-processing the request.

protocol/rpc: move latest added procedures to the end of the array

2013-06-17T16:34:56+00:00

While looking at the newly introduced procedures FALLOCATE and DISCARD,
it seems that these were added with already existing procedure numbers.
This makes the protocol incompatible with existing roll-outs.

It is very confusing when new procedures are added somewhere in the
middle of the array. This will cause the number of existing procedures
to change. It is much preferred to add new procedures at the end of the
array. This changes not only corrects the enum that generates the
procedure numbers, but also the ordering in the client and server
fops-array for clarity.

Correcting this greatly simplifies adding support for these new
procedures in Wireshark and will prevent confusion to the people reading
network traces (with or without Wireshark).

rpc: Cleanup rpc object in TRANSPORT_CLEANUP event

2013-06-16T05:34:28+00:00

rpc_transport object should be alive as long as the rpc_clnt object is
alive. To ensure this, on rpc_clnt's last unref, we cleanup the
corresponding rpc_transport object and complete the rpc_clnt cleanup
later, in a bottom-up fashion.

Introduced rpc_clnt_is_disabled, to allow higher layers to differentiate
between the 'final'[1] disconnect triggered from upper layers, and a
normal disconnect. This differentiation helps in cleaning up resources,
at higher layers, in a race-free manner.

[1] - 'final' here means that the rpc and the associated connection, is
not going to be used anymore. eg - glusterd_brick_disconnect on
volume-stop.

glusterfs: discard (hole punch) support

2013-06-13T21:37:43+00:00

Add support for the DISCARD file operation. Discard punches a hole
in a file in the provided range. Block de-allocation is implemented
via fallocate() (as requested via fuse and passed on to the brick
fs) but a separate fop is created within gluster to emphasize the
fact that discard changes file data (the discarded region is
replaced with zeroes) and must invalidate caches where appropriate.

gluster: add fallocate fop support

2013-06-13T21:37:21+00:00

Implement support for the fallocate file operation. fallocate
allocates blocks for a particular inode such that future writes
to the associated region of the file are guaranteed not to fail
with ENOSPC.

This patch adds fallocate support to the following areas:

	- libglusterfs
	- mount/fuse
	- io-stats
	- performance/md-cache,open-behind
	- quota
	- cluster/afr,dht,stripe
	- rpc/xdr
	- protocol/client,server
	- io-threads
	- marker
	- storage/posix
	- libgfapi

glusterd: Add a cmd for getting uuid of local node

2013-06-10T19:20:05+00:00

Usage: gluster system:: uuid get

This is needed since we generate uuid of a node in a lazy manner. ie, we
generate a uuid for the node only on the first volume or peer operation,
when the node needs an external identity.  With this command, we can
force[1] the uuid generation, without a volume or peer operation performed.

[1]: Querying for uuid (or uuid get), forces uuid to come into
existence.
