5374: Joystick support 🕹️ r=def- a=Robyt3
Port all the joystick support from vanilla:
- Joystick controls
- support for up to 12 axis (we are using the low level SDL interface so we don't differentiate between X/Y axis, sliders etc.)
- two axis can be used for X and Y cursor movement
- cursor input ingame can be relative or absolute
- support for binding up to 12 joystick buttons
- support for binding up to 2 hats (each has 8 directions)
- support for binding axis movement to controls (so you can move with one control stick and aim with the other)
- multiple joysticks can be connected at the same time, but only one can be actively used, the selected joystick will be remembered based on a GUID
- Joystick UI integration
- allow moving the UI cursor with the specified joystick axis
- change `CComponent::OnMouseMove` to `OnCursorMove` to handle joystick separately with its own sensitivity settings
- remove premultiplied mousesens everywhere
- Joystick settings menu (also: separate mouse and movement settings)
Other changes:
- Remove the old unused joystick implementation (with config variable `inp_joystick`).
- Remove an unused parameter.
- Add `CUIEx::DoScrollbarOption` and `IScrollbarScale`
- renders label, current value and scrollbar
- with linear and logarithmic scale implementations
- used for the sensitivity and tolerance settings
- could eventually be used for most scrollbar settings to reduce duplicate code
- has flags for:
- `SCROLLBAR_OPTION_INFINITE`: The scrollbar can be moved all the way to the right for another value that represents ∞. Internally this value is 0.
- `SCROLLBAR_OPTION_NOCLAMPVALUE`: The scrollbar allows values outside the specified min/max range, e.g. the sensitivity settings can technically be as high as 100000 when set with the console.
- Add `CUIEx::DoScrollbarOptionLabeled`
- a `DoScrollbarOption` for selecting from a finite number of options with a scrollbar
- used for switching between relative and absolute input
- might see more use in the future

5252: Use std::vector instead of array, remove base/tl/array.h, algorithm.h, allocator.h, range.h r=def- a=Robyt3
Replaces all usages of `array` with `std::vector`.
I adjusted variable names of variables I changed to use the `v` prefix. Not so in the editor however, as there are already many changes due to clang-tidy enforcing the use of for-each loops.
This allows us to remove all remaining `base/tl` headers except `threading.h`.
Clang-tidy now finds `clang-analyzer-cplusplus.NewDelete` (Use of memory after it is freed), which is also fixed here, though it appears to be a false-positive.
This last remaining usages of `goto` are also removed.

5254: Fix ingame menu button behavior when holding mouse button r=def- a=Robyt3
Fixes the following behavior:
1. Player is ingame and the ingame menu is opened with Esc
2. A mouse button is held down on one of the ingame menu buttons (e.g. the spectate button)
3. The ingame menu is closed without moving the mouse away from the button
4. The mouse button is released while ingame
5. The menu is opened again
- Current behavior: The hovered button is immediately activated, as soon as the menu opens, due to the released mouse state being handled as a click.
- Fixed behavior: The button is not activated. Instead another call to `FinishCheck` is added so it's also called when the menu is not active, to clear the active UI item in that case.
As well as the following:
1. The menu is closed while the mouse cursor is hovering over a button.
2. The mouse button is pressed and held while the menu is closed.
3. The menu is opened again.
- Current behavior: The menu button is already held down and when the player releases the mouse button it will immediately be activated.
- Fixed behavior: The button is not activated immediately, by clearing the hot item and next hot item variables in `FinishCheck`.
The latter behavior can still occur when entering the editor instead of closing the ingame menu.
Closes#3560. Closes#5229.
The first two commits are identical to upstream https://github.com/teeworlds/teeworlds/pull/3158, where those issues also exist. The last commit adapts upstream behavior so buttons can only become hot when the mouse is not pressed.

5246: Use std::vector instead of sorted_array, remove base/tl/sorted_array.h r=def- a=heinrich5991
This replaces all usages of `sorted_array` with `std::vector`. This requires the following general changes:
- `add_unsorted` is replaced with `push_back`.
- `add` is replaced with `push_back` and subsequent `sort` or `stable_sort` must be ensured.
- In some cases, immediately sorting the entire list after adding an item was unavoidable. Previously items were added at the correct position, which was O(N) because all items after the inserted one had to be moved in any case.
- `sort_range` is replaced with `sort` or `stable_sort`.
- `size` returns a `size_t` instead of `int`, so to fix sign comparison warnings, casts are added where necessary or types of loop variables are changed to `size_t` where possible. For-each loops are also used where possible / where required by clang-tidy.
- `find_binary` is replaced with `std::equal_range`. This can only find items of the same type, so some wrappers, that only have the relevant fields set, need to be created for searching.
In terms of behavior, this should not change anything, except maybe `CLocalizationDatabase` for the better. As far as I understand it, at lot of the code there was not doing anything. It assumes that binary search can return a range of multiple entries, but the equality/comparison function is based on hash and context hash. This means that any item in this range will match the given hash and context hash already, so all of the following checks are redundant. I changed this to first do a lookup with the hash and context hash and if that fails do another lookup with the default context hash.
I have also already replaced `base/tl/array.h` with `std::vector`, removing all of `base/tl` except `threading.h`. I'll make a separate PR later because this caused a lot more changes especially in the editor that I first want to test and review myself.
Naming of `array`/`sorted_array`/`std::vector` variables was rather inconsistent (sometimes prefix `a` or `l` is used), so ~~I chose to not use any prefix for all new `std::vector`s~~ heinrich5991 left them as-is.

5063: Reworked Draggers and Turrets AND show always hooks if they are in the field of view r=def- a=C0D3D3V
Fixes#3622, #4723#4798 and #5054
Here you can find a comparison video with 16.0.3: https://youtu.be/bYwLB1cEMI8
This now also includes the changes from https://github.com/ddnet/ddnet/pull/4980
So please also see my monologue here: https://github.com/ddnet/ddnet/pull/4980
Physic that got changed by this PR:
- Solo players are not included in the calculation of the next team players to the dragger/turrets. This does not affect any map.
- Turrets get switched correctly if players are solo
- Plasma bullets fired by turrets on solo player only explode for solo players and the other way around (except if they unsolo)
- Plasma bullets can no longer be intercepted by other teams
- Turrets can shot now independently at the speed of sv_plasma_per_sec for every team and every solo player
This should be tested by some more players before it get merged!
This reduces the use of snap id's tested here: https://youtu.be/G3nVtdH0--Q
from 16000 to 69
test with the new dragger: https://youtu.be/mzNrDHP7HQs
I did not add the terminal of the server because you basically see no change in the used snap ids
The videos are with cl_predict off
Comparison of the new turrets: https://streamable.com/8us8lk

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": {
"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.

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"
],

`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,

```
`--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.

5119: Use STUN to determine UDP connectivity and show diagnostics r=def- a=heinrich5991
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.
