feature/gfid-access: Fix nameless lookup on ".gfid"

2016-07-01T13:30:21+00:00

Backport of http://review.gluster.org/14773

Problem:
In geo-replication, if the data copied from .snaps
directory to the master, the first set of copy after
uss is enabled doesn't get sync to slave.

Cause:
Enabling uss results in graph switch. So when the
lookup comes on "0x00...0d/gfid1" on new graph,
("0x00...0d' being the gfid of virtual directory
 ".gfid"), it fails as gfid-access xlator doesn't
handle it.

Fix:
Handle nameless lookup on ".gfid" in gfid-access
xlator.

build: Filter -D_FORTIFY_SOURCE from CFLAGS

2016-06-29T16:54:02+00:00

We use python-config to get recommended CFLAGS. It provides
-D_FORTIFY_SOURCE=2 by default that conflicts with our
--enable-debug option or a developer provided no-optimization option.
Hence, filter it out from default CFLAGS.

core, shard: Make shards inherit main file's O_DIRECT flag if present

2016-06-16T16:04:10+00:00

        Backport of: http://review.gluster.org/14191

If the application opens a file with O_DIRECT, the shards'
anon fds would also need to inherit the flag. Towards this,
shard xl would be passing the odirect flag in the @flags parameter
to the WRITEV fop. This will be used in anon fd resolution
and subsequent opening by posix xl.

features/changelog: Change barrier notification mechanism

2016-06-16T16:03:15+00:00

Backport of http://review.gluster.org/14272

The barrier notification mechanism was fd based and 'select'
was being used. 'select' breaks when number of fds opened
by brick process exceeds 1024. To avoid this and also
the maintainance of pipe between notify and 'changelog_rollover',
the pipe has been replaced with pthread condition signal
and timed wait mechanism.

For o-direct reads application sends aligned size which needs to be
sent as is, otherwise o-direct writes where the file-size is not
aligned fails.

Revert "features/shard: Make o-direct writes work with sharding"

2016-05-17T11:01:43+00:00

        Backport of: http://review.gluster.org/#/c/14328/

This reverts commit c272c71391cea9db817f4e7e38cfc25a7cff8bd5.

This is for two reasons:
1) It introduces high fop latencies
2) Even with the patch, there is no true odirect behavior since the
   workaround in the patch doesn't reduce the caching done in kernel's
   page cache as far as writes on anon fds associated with individual
   shards is concerned.
