core: have framework for GF_EVENT_CHILD_MODIFIED notifcation event

2011-02-22T10:11:53+00:00

If anything changes anywhere in the graph, all xlators know that
something has changed. Previously dht and afr would mask certain
events from propagating up. Now they forward GF_EVENT_CHILD_MODIFIED
event in those situations

Solaris build fixes

2011-02-22T10:11:25+00:00

Disable geosync build for non-linux platforms.
And fix solaris related build failures.The symbol getxattr was not
 available on solaris. The build on linux passed as getxattr symbol was
available in the library. The argument was not being used, hence
removed it.
Make 64 bit build default in CFLAGS option by passing -m64 option

replicate: set read-child to the subvolume which replied first (fastest)

2011-02-22T10:11:20+00:00

In the old logic read-child was set to the last subvolume which replied.
Now it is updated to the first subvolume. This way we can ensure that local
servers are preferred for reads _most_ of the times.

cluster/afr: stop spawning self-heal loops when the self-heal fails

2011-02-18T07:32:56+00:00

With the current model of self-heal, any loop wont resume if a
self-heal failure happens. I have added the fix to stop spawning the
initial loops on self-heal failure.
Fixed the invalid read shown in valgrind in diff-self-heal.

cluster/replicate: update st_nlink count of stat sent to application after completion of entry-self-heal.

2011-01-08T01:58:44+00:00

- certain applications like 'find' use st_nlink count to optimize searches.
    Hence an incorrect hard link count can result in non-healing of some of
    the newly created subdirectories.
