Subject: Invert two sides of if expression in SET to avoid a lookup.
X-Git-Url: https://git.saurik.com/redis.git/commitdiff_plain/973cb21a0152642ec904cf8f8ab238a31e6ebaa9?hp=973cb21a0152642ec904cf8f8ab238a31e6ebaa9

Invert two sides of if expression in SET to avoid a lookup.

Because of the short circuit behavior of && inverting the two sides of
the if expression avoids an hash table lookup if the non-EX variant of
SET is called.

Thanks to Weibin Yao (@yaoweibin on github) for spotting this.
