--- Comment #277 from Worker Ant <bugzilla-bot at gluster.org> ---
COMMIT: https://review.gluster.org/20919 committed in master by "Amar Tumballi"
<amarts at redhat.com> with a commit message-
{cli-cmd-parser|cli-rpc-ops||cli-xml-output}.c: strncpy()->sprintf(), reduce
strlen()'s

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().

Also:
- save the result of strlen() and re-use it when possible.
- move from GF_CALLOC() to GF_MALLOC() for the strings.
- move from strlen to sizeof() for const strings.

Compile-tested only!
