This reverts commit 7d0397c2144810c8a396e00187a6617873c94002.

license: dual license under GPLV2 and LGPLV3+

2012-05-11T05:06:16+00:00

Note that the license was not changed in any of the following:
	.../argp-standalone/...
        .../booster/...
        .../cli/...
        .../contrib/...
        .../extras/...
        .../glusterfsd/...
        .../glusterfs-hadoop/...
        .../mod_clusterfs/...
        .../scheduler/...
        .../swift/...

The license was not changed in any of the non-building xlators. The
license was not changed in any of the xlators that seemed — to me — to
be clearly server-side only, e.g. protocol/server

Note too that copyright was changed along with the license; I did
not change the copyright in files where the license did not change.

If you find any errors or ommissions please don't hesitate to let me know.

mgmt/glusterd: Avoid re-starting nfs unconditionally.

2012-05-09T05:14:01+00:00

NFS server is restarted unconditionally when a volume option is
configured through the set interface. This patch prevents restart
of NFS server when operations are performed on translators that
are not part of the NFS graph.

This does not prevent re-start of a NFS server when an option
corresponding to a translator that is part of the NFS graph is
re-configured.

cluster/dht: rmdir should succeed last on the hashed subvol

2012-05-09T01:32:56+00:00

mkdir and rename both first happen on the hashed subvol.
Rmdir should succeed, only if all non hashed subvol succeed,
and finally removal from hashed_subvol succeeds.

if hashed_subvol is unavailable, then rmdir should be sent
on all subvols

glusterfsd: Make sure mountpoint is an absolute path

2012-05-09T00:00:21+00:00

If the mountpoint path given to glusterfs is not an absolute path, convert it to
an absolute path by concatenating it with the curren working directory.
This prevents cases, where in gluster cannot perform clean unmounts when mount
is done with a relative path.

when parent belongs to active itable.

When parent is root, the parent inode returned will always be
active_subvol->itable->root and hence there can be cases where we
should explicitly resolve the entry in active graph.

quick-read, md-cache: selectively cache xattr data to conserve memory

2012-05-08T22:34:01+00:00

The md-cache translator can cache items for a long period of time and
thus is sensitive to memory usage associated with the items it
references. This implements two changes to help conserve memory:

- quick-read - Migrate the file content data to a local dict and
	delete from the xdata dict that passes through the stack.
- md-cache - Create a local dict to selectively store the xattr
	data md-cache is interested in. This includes a slight
	optimization to not allocate an empty dict in the case
	where we have not received any xattr's of interest.

I've tested both changes independently and together by running a
readdirp test against several compiled source trees (~340k files).
The base test results in a 7.7GB RSS on the client. The quick-read
modification cuts RSS down to 4.1GB, which is still large due
to md-cache unintelligently caching a large number of empty
dictionaries. The combined modification cuts RSS down to 462MB
on the same workload.

NOTE: Theoretically the md-cache change should supercede the
quick-read change, but practically I save an extra 150MB or so with
both. I already had the change and consider it an improvement that
quick-read clean up after itself.
