This was fine, + * but both version 1 and 2 suck at applying lines efficiently. That is, every time a new line + * was added, it iterated every existing line for every existing user. Ow. Expiry was also + * expensive, as the lists were NOT sorted. + * + * Version 2 moved permanent lines into a seperate list from non-permanent to help optimize + * matching speed, but matched in the same way. + * Expiry was also sped up by sorting the list by expiry (meaning just remove the items at the + * head of the list that are outdated.) * - * Because the old way was horrendously slow, the new way of expiring xlines is very - * very efficient. I have improved the efficiency of the algorithm in two ways: + * This was fine and good, but it looked less than ideal in code, and matching was still slower + * than it could have been, something which we address here. * - * (1) There are now two lists of items for each linetype. One list holds temporary - * items, and the other list holds permanent items (ones which will expire). - * Items which are on the permanent list are NEVER checked at all by the - * expire_lines() function. - * (2) The temporary xline lists are always kept in strict numerical order, keyed by - * current time + duration. This means that the line which is due to expire the - * soonest is always pointed at by vector::begin(), so a simple while loop can - * very efficiently, very quickly and above all SAFELY pick off the first few - * items in the vector which need zapping. + * VERSION 3: + * All lines are (as in v1) stored together -- no seperation of perm and non-perm. They are stored in + * a map of maps (first map is line type, second map is for quick lookup on add/delete/etc). * - * -- Brain + * Expiry is *no longer* performed on a timer, and no longer uses a sorted list of any variety. This + * is now done by only checking for expiry when a line is accessed, meaning that expiry is no longer + * a resource intensive problem. + * + * Application no longer tries to apply every single line on every single user - instead, now only lines + * added since the previous application are applied. This keeps S2S ADDLINE during burst nice and fast, + * while at the same time not slowing things the fuck down when we try adding a ban with lots of preexisting + * bans. :) */ -bool InitXLine(ServerConfig* conf, const char* tag) +bool XLine::Matches(User *u) { - return true;
