Registering
-----------
The idea is that game servers push their server info to the
masterservers every 15 seconds or when the server info changes, but not
more than once per second.
The game servers do not support the old registering protocol anymore,
the backward compatibility is handled by the masterserver.
The register call is a HTTP POST to a URL like
`https://master1.ddnet.tw/ddnet/15/register` and looks like this:
```json
POST /ddnet/15/register HTTP/1.1
Address: tw-0.6+udp://connecting-address.invalid:8303
Secret: 81fa3955-6f83-4290-818d-31c0906b1118
Challenge-Secret: 81fa3955-6f83-4290-818d-31c0906b1118:tw0.6/ipv6
Info-Serial: 0
{
"max_clients": 64,
"max_players": 64,
"passworded": false,
"game_type": "TestDDraceNetwork",
"name": "My DDNet server",
"map": {
"name": "dm1",
"sha256": "0b0c481d77519c32fbe85624ef16ec0fa9991aec7367ad538bd280f28d8c26cf",
"size": 5805
},
"version": "0.6.4, 16.0.3",
"clients": []
}
```
The `Address` header declares that the server wants to register itself as
a `tw-0.6+udp` server, i.e. a server speaking a Teeworlds-0.6-compatible
protocol.
The free-form `Secret` header is used as a server identity, the server
list will be deduplicated via this secret.
The free-form `Challenge-Secret` is sent back via UDP for a port forward
check. This might have security implications as the masterserver can be
asked to send a UDP packet containing some user-controlled bytes. This
is somewhat mitigated by the fact that it can only go to an
attacker-controlled IP address.
The `Info-Serial` header is an integer field that should increase each
time the server info (in the body) changes. The masterserver uses that
field to ensure that it doesn't use old server infos.
The body is a free-form JSON object set by the game server. It should
contain certain keys in the correct form to be accepted by clients. The
body is optional if the masterserver already confirmed the reception of
the info with the given `Info-Serial`.
Not shown in this payload is the `Connless-Token` header that is used
for Teeworlds 0.7 style communication.
Also not shown is the `Challenge-Token` that should be included once the
server receives the challenge token via UDP.
The masterserver responds with a `200 OK` with a body like this:
```
{"status":"success"}
```
The `status` field can be `success` if the server was successfully
registered on the masterserver, `need_challenge` if the masterserver
wants the correct `Challenge-Token` header before the register process
is successful, `need_info` if the server sent an empty body but the
masterserver doesn't actually know the server info.
It can also be `error` if the request was malformed, only in this case
an HTTP status code except `200 OK` is sent.
Synchronization
---------------
The masterserver keeps state and outputs JSON files every second.
```json
{
"servers": [
{
"addresses": [
"tw-0.6+udp://127.0.0.1:8303",
"tw-0.6+udp://[::1]:8303"
],
"info_serial": 0,
"info": {
"max_clients": 64,
"max_players": 64,
"passworded": false,
"game_type": "TestDDraceNetwork",
"name": "My DDNet server",
"map": {
"name": "dm1",
"sha256": "0b0c481d77519c32fbe85624ef16ec0fa9991aec7367ad538bd280f28d8c26cf",
"size": 5805
},
"version": "0.6.4, 16.0.3",
"clients": []
}
}
]
}
```
`servers.json` (or configured by `--out`) is a server list that is
compatible with DDNet 15.5+ clients. It is a JSON object containing a
single key `servers` with a list of game servers. Each game server is
represented by a JSON object with an `addresses` key containing a list
of all known addresses of the server and an `info` key containing the
free-form server info sent by the game server. The free-form `info` JSON
object re-encoded by the master server and thus canonicalized and
stripped of any whitespace characters outside strings.
```json
{
"kind": "mastersrv",
"now": 1816002,
"secrets": {
"tw-0.6+udp://127.0.0.1:8303": {
"ping_time": 1811999,
"secret": "42d8f991-f2fa-46e5-a9ae-ebcc93846feb"
},
"tw-0.6+udp://[::1]:8303": {
"ping_time": 1811999,
"secret": "42d8f991-f2fa-46e5-a9ae-ebcc93846feb"
}
},
"servers": {
"42d8f991-f2fa-46e5-a9ae-ebcc93846feb": {
"info_serial": 0,
"info": {
"max_clients": 64,
"max_players": 64,
"passworded": false,
"game_type": "TestDDraceNetwork",
"name": "My DDNet server",
"map": {
"name": "dm1",
"sha256": "0b0c481d77519c32fbe85624ef16ec0fa9991aec7367ad538bd280f28d8c26cf",
"size": 5805
},
"version": "0.6.4, 16.0.3",
"clients": []
}
}
}
}
```
`--write-dump` outputs a JSON file compatible with `--read-dump-dir`,
this can be used to synchronize servers across different masterservers.
`--read-dump-dir` is also used to ingest servers from the backward
compatibility layer that pings each server for their server info using
the old protocol.
The `kind` field describe that this is `mastersrv` output and not from a
`backcompat`. This is used for prioritizing `mastersrv` information over
`backcompat` information.
The `now` field contains an integer describing the current time in
milliseconds relative an unspecified epoch that is fixed for each JSON
file. This is done instead of using the current time as the epoch for
better compression of non-changing data.
`secrets` is a map from each server address and to a JSON object
containing the last ping time (`ping_time`) in milliseconds relative to
the same epoch as before, and the server secret (`secret`) that is used
to unify server infos from different addresses of the same logical
server.
`servers` is a map from the aforementioned `secret`s to the
corresponding `info_serial` and `info`.
```json
[
"tw-0.6+udp://127.0.0.1:8303",
"tw-0.6+udp://[::1]:8303"
]
```
`--write-addresses` outputs a JSON file containing all addresses
corresponding to servers that are registered to HTTP masterservers. It
does not contain the servers that are obtained via backward
compatibility measures.
This file can be used by an old-style masterserver to also list
new-style servers without the game servers having to register there.
An implementation of this can be found at
https://github.com/heinrich5991/teeworlds/tree/mastersrv_6_backcompat
for Teeworlds 0.5/0.6 masterservers and at
https://github.com/heinrich5991/teeworlds/tree/mastersrv_7_backcompat
for Teeworlds 0.7 masterservers.
All these JSON files can be sent over the network in an efficient way
using https://github.com/heinrich5991/twmaster-collect. It establishes a
zstd-compressed TCP connection authenticated by a string token that is
sent in plain-text. It watches the specified file and transmits it every
time it changes. Due to the zstd-compression, the data sent over the
network is similar to the size of a diff.
Implementation
--------------
The masterserver implementation was done in Rust.
The current gameserver register implementation doesn't support more than
one masterserver for registering.
5155: Remove cl_show_console and -c / --console command line options, attach to existing console r=heinrich5991 a=Robyt3
Alternative to #5154.
Closes#5150.
If you want to open the client with a console window, instead create a new shortcut with the following target:
```
cmd /c "C:\path\to\your\DDNet.exe"
```
You can change the icon of the shortcut to the DDNet icon in the properties of the shortcut file.

Modern hardware is too fast, updates sometimes take less than a few microseconds.
It's easier in the long run if we use a bigger range to avoid calculation problems.
possibly f i x e s #5051 (needs testing from bencie for the main bug, but fixes what `@sjrc6` found)
Also took the moment to use more chrono so we can at some point switch to a typesafe time.
Hopefully I didnt miss any value ^^

Tho since the text container index is so high, i kinda assume its not the only non cleared text container.
Maybe estimating the character count based on the quads used can also help, since then i can see what text is potentially the cause

5142: Handle file/pipe stdout and add fallback on Windows r=def- a=Robyt3
The `CWindowsConsoleLogger` uses `WriteConsoleW` which only works when the standard output handle is a console (`GetFileType` returns `FILE_TYPE_CHAR`).
When redirecting output into a file, `GetFileType` returns `FILE_TYPE_DISK`. For this case a `CWindowsFileLogger` is added that uses `WriteFile` instead. This works on raw bytes, so the UTF-8 encoded lines are written directly.
When pipeing output or when using custom terminals like Git Bash, `GetFileType` returns `FILE_TYPE_PIPE`. I can't find any documentation how to correctly interact with a pipe stdout handle. So in this case, `WriteFile` is also used, because it works for me with cmd, PowerShell and Git Bash.
Lastly, if the output device is unknown, the default `CLoggerAsync` without ANSI colors is used as fallback.
This fixes output not working in Git Bash. Closes#4422. It also fixes output redirected with Git Bash containing additional line breaks.
For consistency, the `CWindowsConsoleLogger` now writes windows line endings also.

5085: New DDRace HUD r=def- a=C0D3D3V
If you want to test this PR, you have to test it on a Server that includes this PR too.
Textures are made by Ravie
Here a showcase video with most parts shown: https://youtu.be/gPTVj-s3pgc
Added to the new HUD
- A display of the weapons available to the player
- The weapon the player is carrying is highlighted
- Indicators for the special abilities of the player (Endless Hook, Endless Jumps, Jetpack, Teleport Weapons)
- Indicators for abilities taken away from the player (Deep/Life Freeze, No Hook, No Weapons collision, No Collision)
- Control indicators for dummy controls (dummy hammer, dummy copy) (bottom right)
- Jump indicator (max 10 jumps ar displayed, and greyed out as soon as a jump is used)
- Ninja status bar that indicates how long a player is capable of using ninja (next to the ninja sword)
- Freeze status bar that indicates the thawing time of a player (below player)
- Movement Information can be displayed in a clean way above the mini score HUD (Position, Speed, Target Angle)
- Indicator if you are in practice mode
The complete HUD also works for players you spectate
I Added a new NetObj since the predicted values are not perfect and would make the display of the information a lot less good: DDNetCharacterDisplayInfo that contains the following information
```
NetIntRange("m_JumpedTotal", -2, 255),
NetTick("m_NinjaActivationTick"),
NetTick("m_FreezeTick"),
NetBool("m_IsInFreeze"),
NetBool("m_IsInPracticeMode"),
NetIntAny("m_TargetX"), # used for the Movement Information display
NetIntAny("m_TargetY"),
NetIntAny("m_RampValue"),
```
So if someone has an idea what data we could also need in the client for making the display more nice, now is the right moment to add more data to this network object.
A few screenshots:

HUD Settings:
Mini Debug HUD:
Speed.X is calculated using the players ramp vaule
