inital commit 2020-08-18 20:42:30 +00:00			`/*`
[refactor] Move files to core/ and servers/ subdirectories CNProtocol, CNShared, CNStructs and Defines are now in core/. CNLoginServer, CNShardServer and Monitor are now in servers/. core/Core.hpp wraps all the core headers except for CNShared.hpp. Defines.cpp has been renamed to Packets.cpp, and so has its corresponding namespace, but not the header file. This is in preparation for upcoming changes. 2021-03-17 19:07:40 +00:00			`* core/CNShared.hpp`
Cleanup for 1.2. Cleaned up whitespace, comments, brace style, etc. Updated tdata reference. 2020-10-19 17:26:14 +00:00			`* There's some data shared between the Login Server and the Shard Server. Of course all of this needs to be thread-safe. No mucking about on this one!`

Replace ifdef guards with #pragma once tl;dr this has potentially significant compilation speed benefits. 2020-08-23 17:14:54 +00:00			`#pragma once`

Tweak CNShared * Separate pruning frequency from timeout * Pluralize CNShared map: login -> logins * Increase connection timeout to 15 minutes * Do not deallocate a nullptr in playerEnter() * Kill connections rejected by playerEnter() * Remove redundant inclusions of mutex headers in a few places 2022-07-31 01:16:07 +00:00			`/*`
Fix early CNShared timeout Revisiting this again; the issue was that the comparison operator was facing the wrong way, so connections were being pruned every 30 seconds or less. This was effectively a race condition kicking an unlucky player every so often when pruning happened exactly during an attempt to enter the game. Now that the proper timeout is being enforced, I've reduced it to 5 minutes, down from 15, since it really doesn't need to be that long. 2022-12-11 17:35:22 +00:00			`* Connecions time out after 5 minutes, checked every 30 seconds.`

Revamp CNShared logic * Use a specialized connection object * Copy the Player object less frequently * Use a randomly generated serial key for shard auth * Refuse invalid shard connection attempts * Clean up connection metadata when a Player joins the shard * Prune abandoned connections when they time out 2022-07-23 22:16:04 +00:00

On login, load Player from DB in shard thread, not in login thread This avoids some needless data shuffling and fixes a rare desync. 2022-12-06 00:07:21 +00:00			`int32_t playerId;`
