Use linkat() instead of link() for portability sake

2014-01-03T06:01:09+00:00

This is a backport of Iccd27ac076b7a74e40dcbaa1c4762fd3ad59da5f

POSIX does not says wether link(2) on symlink should link on
symlink itself or on target. Linux use symlink, most other
systems use target. Using linkat(2) allows the behavior to be
specified, so that the behavior is portable.

Also fix configure test for NetBSD linkat(2), which ceased to work.

cluster/afr: [Feature] Command implementation to get heal-count

2013-10-14T21:41:54+00:00

Currently to know the number of files to be healed, either user
has to go to backend and check the number of entries present in
indices/xattrop directory. But if a volume consists of large
number of bricks, going to each backend and counting the number
of entries is a time-taking task. Otherwise user can give
gluster volume heal vol-name info command but with this
approach if no. of entries are very hugh in the indices/
xattrop directory, it will comsume time.

So as a feature, new command is implemented.

Command 1: gluster volume heal vn statistics heal-count
This command will get the number of entries present in
every brick of a volume. The output displays only entries
count.

Command 2: gluster volume heal vn statistics heal-count
           replica 192.168.122.1:/home/user/brickname

           Here if we are concerned with just one replica.
So providing any one of the brick of a replica will get
the number of entries to be healed for that replica only.

Example:
Replicate volume with replica count 2.

Backend status:
--------------
[root@dhcp-0-17 xattrop]# ls -lia | wc -l
1918

NOTE: Out of 1918, 2 entries are  dummy
entries so actual no. of entries to be healed are
1916.

[root@dhcp-0-17 xattrop]# pwd
/home/user/2ty/.glusterfs/indices/xattrop

Command output:
--------------
Gathering count of entries to be healed on volume volume3 has been successful

Brick 192.168.122.1:/home/user/22iu
Status: Brick is Not connected
Entries count is not available

Brick 192.168.122.1:/home/user/2ty
Number of entries: 1916

core: block unused signals in created threads

2013-09-25T08:33:16+00:00

Block all signal except those which are set for explicit handling
in glusterfs_signals_setup(). Since thread spawning code in
libglusterfs and xlators can get called from application threads
when used through libgfapi, it is necessary to do this blocking.

core: remove all the 'inner' functions in codebase

2012-12-20T07:35:29+00:00

* move 'dict_keys_join()' from api/glfs_fops.c to libglusterfs/dict.c
  - also added an argument which is treated as a filter function if
    required, currently useful for fuse.

* now 'make CFLAGS="-std=gnu99 -pedantic" 2>&1 | grep nested' gives
  no output.
