If I'm reading the code correctly, the conditional and "true" branch
of the ternary expression are dead code since 'request->url' will
unconditionally be NULL due to the:
/* URL is reused for MOVE after PUT */
if (request->state != RUN_PUT) {
FREE_AND_NULL(request->url);
}
earlier in the function. If you want to present a meaningful error
message here, I could imagine squirreling-away the URL so it can be
used in the error message, or re-working the code so that
FREE_AND_NULL(request->url) is only done when and if needed.
