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.
2021-07-17Feature: Persistant rotation of numbered auto/netsave after restart (#9397)Loïc Guilloux
It was always starting from 0 on openttd restart. Now the most recent auto/netsave number will be used as a base to generate the next filename.
2021-07-16Doc: explain in a bit more detail how we implemented STUNPatric Stout
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.

2021-07-11Fix: "Search LAN games" used the socket after it was closed (#9437)Patric Stout
Every outgoing connection, either TCP or UDP, triggered NetworkInitialize(), which triggered NetworkUDPInitialize() which first closes all connections. Now the problem was that "Search LAN games" found a server, added it to the list, after which (over TCP) it queries the server. This closes all UDP sockets (as that makes sense, I guess?), while the UDP was still reading from it. Solve this by simply stop initializing UDP every time we make an outgoing TCP connection; instead only do it on start-up.

2021-07-11Add: allow setting your server visibility to "invite-only" (#9434)Patric Stout
In this mode you do register to the Game Coordinator, but your server will not show up in the public server listing. You can give your friends the invite code of the server with which they can join.
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

2021-07-10Remove: 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!
2021-07-10Remove: old server announcement to Master ServerPatric Stout
As we now use the Game Coordinator for announcements, there is no longer a need to use the Master Server for this.

2021-06-26Codechange: [Network] Remove overload on NetworkValidateClientNamerubidium42
