multiple xlators (mgmt): strncpy()->sprintf(), reduce strlen()'s
xlators/mgmt/glusterd/src/glusterd-geo-rep.c xlators/mgmt/glusterd/src/glusterd-handshake.c xlators/mgmt/glusterd/src/glusterd-sm.c xlators/mgmt/glusterd/src/glusterd-store.c xlators/mgmt/glusterd/src/glusterd-utils.c xlators/mgmt/glusterd/src/glusterd-volgen.c xlators/mgmt/glusterd/src/glusterd-volume-ops.c xlators/mgmt/glusterd/src/glusterd.c strncpy may not be very efficient for short strings copied into a large buffer: If the length of src is less than n, strncpy() writes additional null bytes to dest to ensure that a total of n bytes are written. Instead, use snprintf(). Try to ensure output is not truncated. Also: - save the result of strlen() and re-use it when possible. - move from strlen to SLEN (sizeof() ) for const strings. Compile-tested only! Change-Id: Ib5d001857236f43e41c4a51b5f48e1a33110aaeb updates: bz#1193929 Signed-off-by: Yaniv Kaul <ykaul@redhat.com>
