* cluster/afr - use different dictionaries for sending xattrop requests to ↵Basavanagowda Kanur2009-06-301-24/+50
| | | | | | | | | | | | | | | | each of the subvolume - This patch fixes bug #29. - Using separate copies of dictionaries also eliminates a potential bug in a setup consisting of afr with a posix and client, each having io-threads on top as children. Since posix_xattrop after performing required operations on the xattr array passed in dictionary, sets the result at the same key and in the same dictionary passed as input argument, there can be race conditions where in the results of the operation on posix-child can be sent to the other child as input argument for xattrop, which ofcourse is wrong.

* afr-transaction: handle double flushesAnand V. Avati2009-04-201-1/+3
| | | | __if_fd_pre_op_done - reset fd_ctx->pre_op_done to 0 so that double flushes do not result in two xattrop() calls
* Use original pid when calling the FOP in afr transaction.Vikas Gorur2009-04-161-2/+39
| | | | | | | | Save the original pid while locking and restore it after the FOP is done. This ensures posix-locks can release locks (fcntl) properly. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
