2021-08-10Change: remove the ability to control "max spectators" (#9466)Patric Stout
Soon we will make "join game" join the game as spectator first, so limiting the amount of spectators makes no sense anymore in that context. Not sure it ever did make sense.
2021-07-21Cleanup: remove some references to the old master-serverRubidium
2021-07-21Fix: crash when joining a server again after a TCP disconnect (#9453)Patric Stout
"my_client" wasn't always free'd when a game ended. "my_client" keeps a reference inside the PT_NCLIENT pool. The rest of the code assumes that when you are not in a game, it can freely reset this pool. In result: several ways to trigger a use-after-free.
2021-07-20Feature: allow the use of TURN to connect client and server togetherPatric Stout
TURN is a last resort, used only if all other methods failed. TURN is a relay approach to connect client and server together, where openttd.org (by default) is the middleman. It is very unlikely either the client or server cannot connect to the STUN server, as they are both already connected to the Game Coordinator. But in the odd case it does fail, estabilishing the connection fails without any further possibility to recover.
2021-07-18Feature: [Game Coordinator] Send NewGRF names to the clientRubidium
2021-07-18Feature: [Network] Optionally send NewGRF names with NewGRFs in GameInforubidium42
Before 8a2da49 the NewGRF names were synchronized using UDP packets, however those have been removed. With this a new version of the GameInfo packet is introduced that allows to specify the type of serialisation happens for NewGRFs. Either only the GRF ID and checksum, or those two plus the name of the NewGRF. On this request for local servers will send the NewGRFs names. The Game Coordinator will get the names on the first registration, and after that only the GRF ID and checksum.
2021-07-18Fix c921f6d: [Network] Documentation of Game Info packet was not updatedrubidium42
2021-07-18Remove: the concept of UnknownGRFsrubidium42
These were filled with "<Unknown>" (before 8a2da49) and later their name would get filled via UDP requests to the server. These UDP packets do not exist anymore, so they will always remain "<Unknown>". Remove that logic and just use the generic translated error GRF UNKNOWN string instead.
2021-07-16Feature: allow the use of STUN to connect client and server togetherPatric Stout
This method doesn't require port-forwarding to be used, and works for most common NAT routers in home setups. But, for sure it doesn't work for all setups, and not everyone will be able to use this.

2021-07-14Add: inform clients what game-script a server is running (#9441)Patric Stout

2021-07-11Feature: join servers based on their invite codePatric Stout
This removes the need to know a server IP to join it. Invite codes are small (~7 characters) indentifiers for servers, which can be exchanged with other players to join the servers.
2021-07-11Change: groundwork to allow ServerAddress to use invite codesPatric Stout
Normally TCPConnecter will do a DNS resolving of the connection_string and connect to it. But for SERVER_ADDRESS_INVITE_CODE this is different: the Game Coordinator does the "resolving". This means we need to allow TCPConnecter to not setup a connection and allow it to be told when a connection has been setup by an external (to TCPConnecter) part of the code. We do this by telling the (active) socket for the connection. This means the rest of the code doesn't need to know the TCPConnecter is not doing a simple resolve+connect. The rest of the code only cares the connection is established; not how it was established.
2021-07-11Codechange: track servers with a ServerAddress instead of a NetworkAddressPatric Stout
This allows future extensions to have different ways of referencing a server, instead of forcing to use IP:port.
2021-07-11Feature: raise the maximum NewGRF limit to 255Patric Stout
2021-07-10Feature: allow setting (game) coordinator and content server connection ↵Rubidium
strings using environment variables OTTD_COORDINATOR_CS for the game coordinator defaults to coordinator.openttd.org:3976 OTTD_CONTENT_SERVER_CS for the content server defaults to content.openttd.org:3978 OTTD_CONTENT_MIRROR_CS for the content mirror server defaults to binaries.openttd.org:80
2021-07-10Remove: unused UDP protocol partsPatric Stout
2021-07-10Remove: old server listing via Master ServerPatric Stout
This removes all UDP from the game except for a local broadcast to find LAN games. So long Master Server, and tnx for all the fish!
2021-07-10Add: use Game Coordinator to get latest public server listingPatric Stout

2021-05-13Codechange: [Network] split CloseSocket and CloseConnection more clearly (#9261)Patric Stout
* Codechange: [Network] split CloseSocket and CloseConnection more clearly - CloseSocket now closes the actual OS socket. - CloseConnection frees up the resources to just before CloseSocket. - dtors call CloseSocket / CloseConnection where needed.
2021-05-13Codechange: remove pointless close call due to resolving virtual functions ↵Rubidium
statically in destructors In the destructors of many of the network related classes Close() is called, just like the top class in that hierarchy. However, due to virtual functions getting resolved statically in the destructor it would always call the empty Close() of the top class. Document the other cases where a virtual call is resolved statically.

2021-05-12Change: reworked the debug levels for network facility (#9251)Patric Stout
It now follows very simple rules: 0 - Fatal, user should know about this 1 - Error, but we are recovering 2 - Warning, wrong but okay if you don't know 3 - Info, information you might care about 4 - 5 - Debug #1 - High level debug messages 6 - Debug #2 - Low level debug messages 7 - Trace information
