Previously the playback did not start and no error messages was shown, when the map file cannot be found and no map data is embedded in the demo file.
Minor refactoring: Replace instances of `return pError` with semantically identical `return nullptr` to improve readability.
Make the member variables private and add `SetMin` to replace a usage of the member variables in `CDebugHud`. For completeness/symmetry, `SetMax` is also added.
The return value of `CGraph::InsertAt` was not checked. All uses of the function pass a correct index, so the return value is replaced with an assertion.
As the methods are always called at the same time, they can be combined. This also improves the performance, as the array only needs to be iterated once.
5658: Fix game freezing up on duplicate snapshot r=def- a=Fireball-Teeworlds
If a duplicate snapshot is received (for the same tick), we add both to the SnapshotStorage and end up with the same snapshot as both Cur and Prev. This results in GameInfraTick returning "inf" and results in "NaN" downstream in a few places, getting the CollLine logic stuck.
Some debug info (tcpdump, gdb, perf): https://gist.github.com/Fireball-Teeworlds/ad0016d2551a2e4d4cb5691023493856
Apparently this doesn't really happen in the wild, unless you have a buggy network stack. In which case it happens frequently enough to pinpoint the issue :D

Add `CSnapshot::IsValid` to check if a snapshot unpacked from a snapshot delta or demo is valid:
- ensure number of items and data size are not negative
- ensure that the actual size of the snapshot matches the size derived from its member variables
- ensure item offsets are within the valid range
- ensure item sizes are not negative
Add `CSnapshot::TotalSize` and `CSnapshot::OffsetSize` utility functions.
Minor improvements to related error messages.

5486: Switch to loading screen, when map creation takes too long r=def- a=Jupeyy
Same as #4941
It doesn't directly fix the issue described in #5478, it does however not trigger it anymore. it's still a bug in our code unrelated to this. This just triggered the UB from the issue as `@ardadem` confirmed, SDL received a SDL_QUIT (`[2022-06-23 20:26:31][test]: sdl closed my client, but why xd`)
Now we have a confirmed case that making the window unresponsive can create weird behavior. Similar to the other pr switch to a loading screen after 500ms (this time without menu background map tho, since the menu background map calls the same code).
We really need some fancy loading screen for such situations, even tho they are rare xD

Instead of closing the joysticks manually, use `SDL_QuitSubSystem(SDL_INIT_JOYSTICK)` to quit the entire subsystem, which will also close all joysticks correctly.
The engine input destructor is replaced with a `Shutdown` method so we can control when it is called, i.e. before calling `SDL_Quit`, which forcefully quits all subsystems.
`CJoystick::Close` is removed as we don't need to close joysticks manually anymore.

5106: Fix dummy intended tick sent to server r=def- a=sjrc6
fixes https://github.com/ddnet/ddnet/issues/5044
Currently the dummy gives the server the wrong IntendedTick aka PredTick which (I think) makes it impossible for the server to correctly order inputs if they come early (i.e. if you're playing with high prediction margin).
Currently with dummy copy if you switch dummy with high prediction margin it will almost always desync, with this change it doesn't desync.
The only reason dummy works at all is because it relies on this code in the server to change the tick that was sent to be the current game tick, if you remove it then dummy hammer and dummy copy breaks but normal players are unaffected.
e9b59e72ff/src/engine/server/server.cpp (L1632-L1633)
I marked this PR as draft because it seems to cause some unexpected side effects:
with this change if you use dummy copy in solo part your dummy will be visually delayed, this doesn't change anything but it's different from how it was before and I don't understand why.
the sound effects from hooking with dummy copy are also not as synced as they are with the wrong tick being sent (not sure why)
I also didn't test all dummy mechanics or any advanced dummy binds which might somehow rely on the broken behavior.
With wrong tick sent to server:

5064: Add HTTP masterserver registering and HTTP masterserver r=def- a=heinrich5991
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:
```http
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": {

"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.

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": {

"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"
},

}
},

},
"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.
These diagnostics are supposed to guide the user to problem resolution.
They're displayed if no packet is received from the server within one
second of connecting.
No message if we don't have STUN servers.
"Trying to determine UDP connectivity..." if no answer has been received
from the STUN server yet and it hasn't timed out yet.
"UDP seems to be filtered." if the STUN request has timed out.
"UDP and TCP IP addresses seem to be different. Try disabling VPN,
proxy or network accelerators." if the STUN request has returned an IP
address different from the one obtained via HTTP from info2.ddnet.tw.
"No answer from server yet." otherwise, if the STUN request has returned
no interesting data, indicating that it's likely the game server's
fault.
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.

4509: Switch new players to DDNet config dir, support Teeworlds as fallback r=heinrich5991 a=def-
This way new players will get DDNet directory, old ones can switch

If we ever enforce a switch in a future version, this will make it

- Added RenderMovementInformation() to the HUD
- Use m_Width instead of recalculating the display width each time in hud.cpp
- Reworked Debug HUD:
- Display velspeed.x*ramp and velspeed.y instead of velspeed*ramp
- Show unit of speed
- The graph for the velspeed.x*ramp behavior (if dbg_tuning is active) is now nicer and usable. A second graph zooming in on the turning point has been added.
- The velspeed.x*ramp graph will be redrawn only when new tuning parameters are added
- The target angle used to draw the tees is now calculated using the m_TargetX, m_TargetY in DDNetCharacterDisplayInfo if available.
- Added m_TargetX, m_TargetY and m_RampValue to DDNetCharacterDisplayInfo Snap (m_RampValue has a precision of one thousandth)
- Added CGraph::InsertAt() to create static Graphs
- Added "assets/hud" to initial created Directories
- Added Settings to hide Dummy Action HUD and Player Movement HUD cl_showhud_dummy_actions, cl_showhud_player_position, cl_showhud_player_speed, cl_showhud_player_angle
- Added Pointer to m_PrevExtendedDisplayInfo, for calculation of interpolated Angle in Player Rendering
- Added GetDigitsIndex(int Value, float Max); to hud.cpp

On the one hand variables called "Dummy" would tell us whether the
current action refers to the currently inactive tee ("dummy"). On the
other hand, these variables could tell us whether the current action
refers to the main connection to the server, or the secondary one. The
latter use case is now renamed to "Client", with the choices
`CLIENT_MAIN`, `CLIENT_DUMMY` (and `CLIENT_CONTACT`).
Perhaps better names could be found, especially since `Client` also
refers to the engine client class in the game code.
I tried to not fix bugs unless it would complicate the code.
4581: Adjustable prediction margin r=def- a=trml
This adds an option to adjust how early the client sends an input for a given tick. In vanilla this value is hardcoded to 10 milliseconds before the next tick, which is good for low-latency gameplay and/or when you have a stable connection, but sometimes it could perhaps be useful to increase the value, to either test something with a high ping (without having to joing a high-ping server or use on a 3rd party program like tc/netem), or for counteracting the effect of jitter and jumping ping.
The last part comes at a tradeoff for higher ping though, and it also doesn't handle lag caused by packet loss, but it I have found it useful in some situations when playing race/solo/dummy with a bad connection. Since it's a bit experimental I only added it as an f1 option and not stored between sessions, and also added a gameinfo flag to only support it on servers that implement #1441.
Edit: Also attempted to cleanup variable names for tick calculations in client.cpp slightly.

4590: Remove extra projectiles r=def- a=trml
Aligns the code with vanilla, and cleans up things a bit
(same as [329e6261f3](url))
These were used to show projectiles a tick (or fraction of a tick) earlier than they otherwise would (and they were also sent without extrainfo since they didn't matter for prediction), so removing them would perhaps not make a noticeable difference. (and perhaps also less of a difference now since weapon input isn't applied before the start of a tick anymore).

4607: Adopt upstream input (especially double click) handling, refactoring r=def- a=Robyt3
This adopts the 0.7 way of handling double clicks, by checking `Event.button.clicks` of the `SDL_Event`. The double click is stored as a flag which is cleared when the `MouseDoubleClick()` function is called (d215c73206 and 7977b46d36).
This reverts 72a6e20, as this hack is no longer required (closes#1745). Double clicking a friend in the friend list still works (#444) with both `gfx_asyncrender_old 0` and `1`.
Refactorings and minor fixes synchronizing with upstream:
- Only copy SDL keystate of _keyboard_ keys and mem_zero the rest to ensure out of bounds SDL keys don't trigger mouse keys.
- Rename variables and use SDL constants.
- Reduce unnecessary indentation.

Currently to show your own key presses when recording you need
cl_video_showdirection 1 and cl_show_direction 2 which is kind of
unintuitive.
Also changed the name to be consistent with cl_show_direction

4158: Make emoticons smoother r=heinrich5991 a=Jupeyy
It's still not 100% the same as with high bandwidth, but atleast animation wise it should look the same.
The client doesn't predict if an emote actually is triggered, so it still only triggeres them every second tick without high bandwidth.
~Since this changes demo playing quite a bit, it should defs be tested~(not really xd)
fixes#4156

This reverts commit ce2f29b5f1.
The commit message is misleading. DDNet already had the pid.tmp behavior.
This just uses more the teeworlds style of doing it.

Fix https://github.com/teeworlds/teeworlds/issues/2645
The `Sv_ReadyToEnter` net message is only valid while we're still
loading stuff, it is used to signal that we can send the `ENTERGAME`
system message. Simply ignoring the server message while we're in the
wrong part of the state machine works.

3888: Send server info request for ping with different token r=Jupeyy a=heinrich5991
Thanks to @Jupeyy for figuring out this bug.
Previously, the client would send the request for server info and the
server info ping packet with the same token, making the answer
indistinguishable from each other. Fix this by generating a token that
won't collide.
Fixes#3862.

3873: Add japanese compressed font r=def- a=TsFreddie
This is a 57kb hiragana/katakana font sits between deja vu sans and source han sans. GlowSansJCompressed is a fork of Source Han Sans so the style and license are the same: https://github.com/welai/glow-sans/blob/master/docs/README-en.md
Was torn between condensed (thiner) font and compressed (thinnest) font, but I figure since we want to fit them better, might as well make more text fit rather than less:
The font weight is "book" because glow sans has 9 font weights instead of matching source han sans's 7. so the weight name was shifted.
_Japanese translation will come later._

3772: Add client-side HTTP server info r=def- a=heinrich5991
Summary
=======
The idea of this is that clients will not have to ping each server for
server infos which takes long, leaks the client's IP address even to
servers the user does not join and is a DoS vector of the game servers
for attackers.
For the Internet, DDNet and KoG tab, the server list is entirely fetched
from the master server, filtering out servers that don't belong into the
list.
The favorites tab is also supposed to work that way, except for servers
that are marked as "also ping this server if it's not in the master
server list".
The LAN tab continues to broadcast the server info packet to find
servers in the LAN.
How does it work?
=================
The client ships with a list of master server list URLs. On first start,
the client checks which of these work and selects the fastest one.
Querying the server list is a HTTP GET request on that URL. The
response is a JSON document that contains server infos, server addresses
as URLs and an approximate location.
It can also contain a legacy server list which is a list of bare IP
addresses similar to the functionality the old master servers provided
via UDP. This allows us to backtrack on the larger update if it won't
work out.
Lost functionality
==================
(also known as user-visible changes)
Since the client doesn't ping each server in the list anymore, it has no
way of knowing its latency to the servers.
This is alleviated a bit by providing an approximate location for each
server (continent) so the client only has to know its own location for
approximating pings.

3492: Support F-Client and replace non-extended extension messages r=Learath2 a=heinrich5991
This continues what #3439 started, and also replaces non-extended messages that are DDRace extensions with extended messages. The DDNet server still sends the old message to old clients and the DDNet client still understands the old messages.
Supersedes #3439.
