glupy patch by Ram, Justin: Add/Modify fops, structure types, utility fns
Extend the following fops with Python: * open * readv * writev * opendir * readdir * readdirp * stat * fstat * statfs * setxattr * getxattr * fsetxattr * fgetxattr * removexattr * fremovexattr * link * unlink * readlink * symlink * mkdir * rmdir Add fd_t, inode_t and iatt_t structure types. Modify loc_t structure type; Alter the data types of the following attributes - inode, parent, gfid, pargfid. Modify uuid2str function, which returns a string equivalent for a ctype object representing a gfid, to make use of python's 'uuid' module for accurate representation of uuids. by Justin Clift: Adjust debug-trace.py to work with Python 2.6 Work around 'zero length field name in format' bug in negative.py's uuid2str function Fix indentation errors in negative.py, glupy.h, glupy.c, gluster.py Change-Id: If0fcfb2866e21c0380a973f8ffab9ea7b6a4cd5d BUG: 961856 Signed-off-by: Ram Raja <rraja@redhat.com> Reviewed-on: http://review.gluster.org/4907 Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-by: Justin Clift <jclift@redhat.com> Tested-by: Justin Clift <jclift@redhat.com>

+Loading a translator written in Python using the glupy meta translator
+-------------------------------------------------------------------------------
+'test.vol' is a simple volfile with the debug-trace Python translator on top
+of a brick. The volfile can be mounted using the following command.
+
+$ glusterfs --debug -f test.vol /path/to/mntpt
+
+If then file operations are performed on the newly mounted file system, log
+output would be printed by the Python translator on the standard output.
