Nobody really paid attention to the lobby window, and it completely
missed its purpose. Most people don't even wait for companies to
show up, but just hit "New Company".
This in turn means people create a lot of unneeded companies, while
they "just want to watch the game" or join another company.
Instead, "Join Game" now just joins the game as spectators.
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.
"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.
Rename the zero-parameter NetworkValidateClientName to NetworkValidateOurClientName to make it clearer it is performed on our client name, and to make it a non-overloaded function to aid with the variant being added a few commits later
* 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.
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
The code mixed up "client has quit but we already told everyone"
with "client lost connection, handle this".
Split up those two signals:
- CLIENT_QUIT means we told everyone and the connection is now dead
- CONNECTION_LIST means we should tell everyone we lost a client
We now resolve the connection_string to a NetworkAddress in a much
later state. This means there are fewer places constructing a NetworkAddress.
The main benefit of this is in later PRs that introduce different types
of NetworkAddresses. Storing this in things like NetworkGameList is
rather complex, especially as NetworkAddress has to be mutable at all
times.
Additionally, the NetworkAddress is a complex object to store simple
information: how to connect to this server.
This means that pressing Refresh button and adding servers manually
now uses TCP.
The master-server and initial scan are still UDP as they will be
replaced by Game Coordinator; no need to change this now.
If we query a server that is too old, show a proper warning to the
user informing him the server is too old.
The lobby of a server requested some parts via UDP and some via
TCP. This is strictly seen fine, but for future extensions it
is a lot easier if just one protocol is used.
The GUI now more clearly shows some basic information about the
server you joined, your client name (and the ability to change it),
and what players are in which company.
It also contains useful buttons to press to join companies, chat
with other people, and for admins to kick/ban people.
Additionally, renamed "advertised" to "visibility"; this has to
do with future additions, but also because it is more clear in
wording.
This so names from other clients are known valid in the client as well, instead allowing some compromised/bad server to potentially crash clients upon certain expectations.
The original idea was that people could find a server they could
talk in their native language on. This isn't really used in that
way. There are several reasons for removing this:
- the client also sends his "language" to the server, but nothing
is doing anything with this.
- flags are a bad way to represent languages, and over the years
we had several (rightfully) complaints about this.
- most servers have their language set to "All", and prefix the
servername with the language it is about. This is a much more
efficient way to do the same.
All in all, this feature should go back to the drawing board.
Maybe it could work in another form, but this form is not it.
This is a much better location for this button, as you send
money from one company to another company, not from player
to player.
This is based on work done by JGRPP in:
f820543391
and surrounding commits, which took the work from estys:
https://www.tt-forums.net/viewtopic.php?p=1183311#p1183311
We did modify it to fix several bugs and clean up the code while
here anyway.
The callback was removed, as it meant a modified client could
prevent anyone from seeing money was transfered. The message
is now generated in the command itself, making that impossible.
