A mod that fixes the slow/infinite server data loading in the multiplayer menu.
Also prevents you from spamming "refresh" too much.
This mod does 3 things to fix up that mess of a server pinger, all of which are in the ServerListEntryNormal
& prevent you from starting too much. This greatly improves things especially when you spam "refresh", as you're now capped to serverCount * 2 tasks, unlike in vanilla where you can basically queue infinitely many tasks.
When too many tasks are already running and you try to refresh, the server text will be set to "Spamming...", in which case you'll have to wait a few sec and hit refresh again
(the pinger is field_148302_b in the used 1.8.9 mappings, which is a ScheduledThreadPoolExecutor)
By default this is set to 5, which is REALLY low, especially if you have a lot of servers.
Even more so if you had some servers that failed to ping, in which case you'd usually get stuck completely after only a few refreshes at most.
This is now changed to serverCount + 5, which is eg if you have 21 servers is 26.
(Note that this gets caped to "Max threadcount (Pinger)", which is by default 50. So if you have 46 or 80 or 999 servers in your serverlist, you'll still only have at most 50 concurrent tasks if using the default config)
This is made by adding another ScheduledThreadPoolExecutor, and then adding ping tasks to it using final Future<?> future = timeoutExecutor.submit(getPingTask());
The field_148302_b.submit(...) (pinger) vanilla calls are then replaced with ones that call future.get(timeout) instead of the ping task directly, causing the pinger to not get overloaded and to properly fail on timeouts after by default 4 seconds (which you can change in the config).
I currently only have plans to port up to 1.12 (Forge obviously), if possible using ReplayMod's preprocessor to keep a single codebase. I didn't look at 1.12's code yet, but knowing mojang I doubt they changed the class I mixin into to a point it'd need a serious rewrite.
Once that's done, i'll (maybe) consider newer versions, and if I do i'll probably support as much versions as possible
