Segmentation fault when execution time of LUA script exceeds timeout #437
Description
Hi, I'm getting segmentation fault error when execution time of lua script exceeds timeout defined in Redis::connect(), here is example code:
<?php
$lua = '
for y = 1, 10, 1 do
for i = 1, 100000, 1 do
redis.call("sAdd", "foo", i)
end
for i = 1, 100000, 1 do
redis.call("sRem", "foo", i)
end
end
';
$redis = new Redis();
$redis->connect("localhost", NULL, 1);
$sha = $redis->script("load", $lua);
$redis->evalsha($sha);and here is gdb output:
(gdb) run redis.php
