* build: do not #include "config.h" in each fileNiels de Vos2015-05-291-5/+0
| | | | | | | | | | | | | | | | | | Instead of including config.h in each file, and have the additional config.h included from the compiler commandline (-include option). When a .c file tests for a certain #define, and config.h was not included, incorrect assumtions were made. With this change, it can not happen again.

* cluster/ec: data heal implementation for ecPranith Kumar K2015-05-081-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | Data self-heal: 1) Take inode lock in domain 'this->name:self-heal' on 0-0 range (full file), So that no other processes try to do self-heal at the same time. 2) Take inode lock in domain 'this->name' on 0-0 range (full file), 3) perform fxattrop+fstat and get the xattrs on all the bricks 3) Choose the brick with ec->fragment number of same version as source 4) Truncate sinks 5) Unlock lock taken in 2) 5) For each block take full file lock, Read from sources write to the sinks, Unlock 6) Take full file lock and see if the file is still sane copy i.e. File didn't become unusable while the bricks are offline. Update mtime to before healing 7) xattrop with -ve values of 'dirty' and difference of highest and its own version values for version xattr 8) unlock lock acquired in 6) 9) unlock lock acquired in 1) Change-Id: I6f4d42cd5423c767262c9d7bb5ca7767adb3e5fd BUG: 1215265 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/10384 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
* libglusterfs: Implement cluster-syncopPranith Kumar K2015-04-251-0/+126
This patch implements syncop equivalent for cluster of xlators. The xlators on which the fop needs to be performed is taken in input arguments to the functions and the responses are gathered and provided as the output. This idea is taken from afr-v2 self-heal implementation by Avati.
