* Updated Upstream (Bukkit/CraftBukkit) Upstream has released updates that appears to apply and compile correctly. This update has not been tested by PaperMC and as with ANY update, please do your own testing Bukkit Changes: 45690fe9 SPIGOT-5047: Correct slot types for 1.14 inventories CraftBukkit Changes: 4090d01f SPIGOT-5047: Correct slot types for 1.14 inventories e8c08362 SPIGOT-5046: World#getLoadedChunks returning inaccessible cached chunks. d445af3b SPIGOT-5067: Add item meta for 1.14 spawn eggs * Bring Chunk load checks in-line with spigot As of the last upstream merge spigot now checks ticket level status when returning loaded chunks for a world from api. Now our checks will respect that decision. * Fix spawn ticket levels Vanilla would keep the inner chunks of spawn available for ticking, however my changes made all chunks non-ticking. Resolve by changing ticket levels for spawn chunks inside the border to respect this behavior. * Make World#getChunkIfLoadedImmediately return only entity ticking chunks Mojang appears to be using chunks with level > 33 (non-ticking chunks) as cached chunks and not actually loaded chunks. * Bring all loaded checks in line with spigot Loaded chunks must be at least border chunks, or level <= 33

Subject: [PATCH] Performance & Concurrency Improvements to Permissions
|
|
|
|
Modifying of permissions was only half protected, enabling concurrency
|
|
issues to occur if permissions were modified async.
|
|
|
|
While no plugin really should be doing that, modifying operations
|
|
are not heavily called, so they are safe to add synchronization to.
|
|
|
|
Now, all modification API's will be synchronized ensuring safety.
|
|
|
|
Additionally, hasPermission was victim to a common java newbie mistake
|
|
of calling if (containsKey(k)) return get(k), resulting in 2 map lookups.
|
|
|
|
Optimized it to simply be a single get call cutting permission map
|
|
lookups in half.
