1. Local variable 's' hides a parameter of the same name. ``` int anetTcpAccept(char *err, int s, char *ip, size_t ip_len, int *port) { if ((fd = anetGenericAccept(err,s,(struct sockaddr*)&sa,&salen)) == ANET_ERR){} } ``` Change the parameter name from `s` to `serversock`, also unified with the header file definition. 2. Comparison is always false because i <= 48. ``` for (i = 0; i < DICT_STATS_VECTLEN-1; i++) { // i < 49 (i == DICT_STATS_VECTLEN-1)?">= ":"", // i == 49 } ``` `i == DICT_STATS_VECTLEN-1` always result false, it is a dead code. 3. Empty block without comment. `else if (!strcasecmp(opt,"ch")) {}`, add a comment to avoid warnings. 4. Bit field fill of type int should have explicitly unsigned integral, explicitly signed integral, or enumeration type. Modify `int fill: QL_FILL_BITS;` to `unsigned int fill: QL_FILL_BITS;` 5. The result of this call to reconnectingRedisCommand is not checked for null, but 80% of calls to reconnectingRedisCommand check for null. Just a cleanup job like others.
