98634d5aa2 New buff framework (player implementation)
Get rid of `iConditionBitFlag` in favor of a system of individual buff
objects that get composited to a bitflag on-the-fly.
Buff objects can have callbacks for application, expiration, and tick,
making them pretty flexible. Scripting languages can eventually use
these for custom behavior, too.

TODO:
- Get rid of bitflag in BaseNPC
- Apply buffs from passive nano powers
- Apply buffs from active nano powers
- Move eggs to new system
- ???

306a75f469 The great re-#include
Was getting frustrated by the inconsistency in our include statements,
which were causing me problems. As a result, I went through and manually
re-organized every include statement in non-core files.

I'm just gonna copy my rant from Discord:
FOR HEADER FILES (.hpp):
- everything you use IN THE HEADER must be EXPLICITLY INCLUDED with the exception of things that fall under Core.hpp
- you may NOT include ANYTHING ELSE

FOR SOURCE FILES (.cpp):
- you can #include whatever you want as long as the partner header is included first
- anything that gets included by another include is fair game
- redundant includes are ok because they'll be harmless AS LONG AS our header files stay lean.

the point of this is NOT to optimize the number of includes used all around or make things more efficient necessarily. it's to improve readability & coherence and make it easier to avoid cyclical issues

4825267537 Use memcpy() instead of casting to load keys
UBSAN complains about the casting approach because it loads a 64-bit
integer from the defaultKeys string which isn't guaranteed to be 64-bit
aligned, which is undefined behavior.

a92cfaff25 Differentiate new connection messages on the login and shard ports 2023-03-11 21:54:56 +01:00
3f44f53f97 On login, load Player from DB in shard thread, not in login thread
This avoids some needless data shuffling and fixes a rare desync.

eb8e54c1f0 Do not evaluate timers if the server is shutting down
This should fix issues with segfaults when the server is being
terminated that sometimes occur because things like NPC path traversal
keep running while the process is executing the signal handler.

ca0d608a87 Use cryptographic RNG to generate the shard connection serial key 2022-07-24 21:36:03 +02:00
741bfb675b 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

05d6174351 Handle email dumping separately from chat dumping
This makes it actually possible to unambiguously parse the full thing
on the receiving end.

70c3650ee1 Add config option to disable the localhost workaround
There are some network configurations in which it's undesirable; such as
reverse tunneling through ssh. These are obscure enough to allow leaving
the option undocumented (in the example config file).

a57953393d [refactor] Convert CNLoginServer handlers to new sendPacket() wrapper

a55a34e09a [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.
