Using an `std::vector` is simpler and more readable than first allocating a linked list on a heap and later copying the list to an array.
The variable `m_SeekablePoints` is removed from `CPlaybackInfo`, as it does not need to be exposed outside of `CDemoPlayer` and can be replaced with the size of the vector.
Previously all demo players checked `IVideo::Current` to render a video, which would cause issues when rendering a demo while a demo slicing background job is running. Now video rendering can be toggled for each demo player individually and is only enabled for the main demo player.
Use member instead of static variables for demo player snapshot data. The static variables would otherwise cause issues when multiple demo players are playing at the same time, especially demo players used in background jobs for replay demo slicing. This hopefully closes#7068.
Use composition instead of inheritance for demo player listener to avoid temporarily storing a pointer to a local variable in a member variable.
Fix demo player file not being closed when demo recorder file cannot be opened during demo slicing.
Add assertions to check that demo recording/playback is not started when already running.
Add assertions to check that demo recording/playback is stopped before the respective demo recorder/player is destroyed.
Improve layout of demo browser buttons, search and checkbox. Use icons for most buttons. Decrease size of UI elements.
Move demo details from below the file browser to a side panel on the right, which is the same size as the server browser side panel. Use ellipsis to truncate the SHA256 instead of rendering only half of it with reduced font size. Show "map not included" instead of "0.00 KiB" for the map size of demos that don't include a map.
Remove the "Markers" column, as it is not very useful to see for all demos and sort by.
Closes#7275.
Simplify the usage of datafile reader and writer by adding utility functions to read and write zero-terminated UTF-8 strings.
Improve validation of string data read from datafiles. It is ensure that string data is null-terminated, has no internal NUL-characters and is valid UTF-8.
Fix loading of external sounds in the editor. The wrong path variable was being used, so the sound files would not be loaded from correct folder.
Add tests for new datafile reader/writer functions.
When `IMap::Load` fails, other components will continue to use the old map. However, if `IMap::Load` failed after the map was already successfully read with the datafile reader then other components kept their pointers to the old, invalid datafile reader items and data, causing random crashes in collision code. This is fixed by using a separate datafile reader to read the new map and only applying the datafile reader globally when loading was entirely successfully.
An error message is added for the case that a map has an unsupported version, which is currently the only case where a map can fail to load after the datafile was read successfully.
In particular, the block maps `blmapPepe`, `blmapV5` and `blmapDT-UPTU` did not have a version map item and were fixed separately.
Closes#7218. Regression from #5737.
Instead of keeping track of a permanently empty `CSnapshot` object in client and server separately, add `CSnapshot::EmptySnapshot` to access a singleton empty `CSnapshot`.
Mark pointer parameters of snapshot functions as `const` when possible.
Previously, if the demo header strings did not contain zero-termination, the client would render the strings and any following non-zero memory from the demo header.
Now, demos will not be loaded, if any string in the header is not zero-terminated or not valid UTF-8.
Most variables used in the sound engine were static globals, as they are used in the static sound mixing function. The global variables are replaced by member variables, by passing the sound interface as user-data for the SDL mixing callback. The `Mix` function is made a public member function of `ISound` instead of being exposed using `ISoundMixFunc GetSoundMixFunc()`.
This allows to remove the direct dependency of the engine sound on the engine video, by instead passing the sound mixing function as a lambda to the engine video in the engine client.
The old WavPack reader function interface does support passing a user-data pointer to the callback function, so global variables are still used here.
Don't truncate console lines at 255 bytes anymore. Especially lines containing many Unicode characters would be adversely affected by this limitation.
Instead, truncate console lines after 10 wrapped lines are rendered. Rendering too many lines at once currently breaks the console scrolling. Rendering an ellipsis is currently not possible when rendering text with a maximum line count.
Increase buffer sizes to handle long (esp. invalid) command inputs.
Closes#7132.
Use `WaitForPipeDrain` to deterministically wait for the pipe to drain instead of using `Start-Sleep`.
Use `Dispose` instead of `Close` to properly flush and close the pipe stream.
Add error handling for connection timeout and I/O errors.
Handle `ERROR_BROKEN_PIPE` separately when peeking at pipe, as this happens when the pipe is disconnected immediately after connecting it or after reading the previous message.
Don't ignore `ERROR_BAD_PIPE` anymore, as the pipe should never be in a disconnected (i.e. bad) state at this point of the function.
This config variable was only settable in the server console but only read in the client, so it was effectively unusable. It also has no use case right now.
Render a pause/play icon in the center of the screen when pausing/unpausing while the menu is not active.
The icon fades in and out over 0.5 seconds and slightly increases in size over that time.
When starting demo rendering with initial pause, the pause indicator is rendered continuous until playback is first started, to ensure that the initial pause state is communicated clearly to the user. The initial pause indicator is not included in the rendered demo, but pausing and unpausing later during demo rendering will cause it to be included in the video, same as other UI elements. Closes#7044.
The config variable `cl_demo_show_pause` (`0/1`, default `1`) is added to hide the pause indicator entirely, for example to render a demo with multiple pauses without the indicator.
The pause indicator and also the existing speed indicator are not rendered (anymore) while the menu is active, as the menu already contains this information.
Add more efficient function for formatting integer values as strings.
A benchmark shows that using this function is significantly faster than using `str_format`. It is faster by a factor of 220 with Clang 15.0 O2 (https://quick-bench.com/q/BlNoLnlyqxipf4jvsFTUxKMHDJU) and by a factor of 11 with GCC 12.2 O2 (https://quick-bench.com/q/Fxf9lDCTqXBF4pIa_IyZ5R0IqYg).
This increases FPS in the editor by ~25% when many numbers are rendered for switch/tele/speedup/tune layers or with "Show Info" being enabled.
The additional static analysis for `std::to_chars` revealed that the wrong size was used in `CHud` for `aScoreTeam[TEAM_RED]` and `aScoreTeam[TEAM_BLUE]`.
This requires incrementing the macOS deployment target from 10.13 to 10.15.
`shared_ptr`s of `CServer::m_pDnsblLookup[ClientID]` are set, but not
cleaned up when done. Therefore the Job is kept alive until the player
disconnects and a new player joins on that slot. Currently this means
that the full linked list of jobs is kept alive.
When the Job is overwritten with a new job, all the remaining objects in
the list can be dropped. With enough jobs, that is causing a stack
overflow in the destructor.
This patch fixes this overflow by making the lifetime independent of the
previous Job. Jobs can get dropped after processing them, even when the
previous job is still alive.
Fixes#6954
The old code looked pretty weird. It checked for `CFGFLAG_SERVER |
CFGFLAG_GAME` being set above, and then used the passed-in parameter to
find the command. I think it'd be better to just look for `CFGFLAG_GAME`
and then find the command using `CFGFLAG_GAME`.
Check if datafile data cannot be read entirely (according to the data size specified in the header) and check for decompression errors. In case of errors, let `GetData` return `nullptr` and `GetDataSize` return `0` for the respective index.
Internally the decompressed size is set to `-1` for data which failed to load, so loading of those data will not be attempted again because it would only fail again and can cause additional log messages.
Port the `CJsonWriter` utility class from upstream, which makes outputting correct JSON easier.
Add `CJsonWriter` as an abstract class that can write to different outputs. Two implementations `CJsonFileWriter` (writes to a file) and `CJsonStringWriter` (writes to an `std::string`) are added. Upstream `CJsonWriter` can only write to files.
The same tests are added for both implementations. Duplicate code is avoided by using typed tests with two separate test fixtures.
`stdout_output_level` for printing to stdout, `console_output_level` for
printing to local console and remote console and `loglevel` for the log
file.
Keep the old log level filters 0 for info and more severe, 1 for debug
and more severe and 2 for trace and more severe, introducing -1 for
warn, and -2 for error. -3 will show no log messages at all.
Port map and editor support for `CURVETYPE_BEZIER` from upstream, i.e. support bezier curves with configurable in- and out-tangents for every envelope point.
The in- and out-tangents are represented by triangles and can be dragged in the envelope editor like the envelope points.
Support reading and writing the bezier information as a separate UUID-based map item. If the bezier information is not found, bezier will default to linear behavior. Old clients will still be able to read the new maps and ignore the unknown map item. The unknown curvetype will also be handled as linear by old clients.
Allow reading upstream maps that use `CMapItemEnvelope` version 3. On upstream, a different struct is used to store all envelope points including bezier information, which broke compatibility to old clients.
Fix holding Ctrl for slow envelope point editing not working for vertical movement.
Highlight the currently selected element (envelope point or bezier tangent marker) which is being used with the value/time edit boxes.
Hide the value/time edit boxes when no element is selected.
Previously it reported the internal file data size (compressed). This
made the `map_resave` tool do the wrong job.

To reduce duplicate code and to add validation for tile skip everywhere.
Add separate `CMapItemLayerTilemap::TILE_SKIP_MIN_VERSION` constant and change `CMapItemVersion::CURRENT_VERSION` back to the previous version, as maps with tile skip can be loaded but skip is not used when saving.
When multiple files or folder have the same name in multiple storage locations, only pass the first entry (file or folder, whichever comes first) to the callback. To prevent files with the same name form being listed multiple times, e.g. in the demo browser, editor file browser, and asset lists.
6755: Remove individual RGBA sliders from editor color picker, add shift+rightclick/leftclick to copy/paste color in editor r=Jupeyy a=Robyt3
Remove the individual RGBA sliders for editor color pickers and only show one button that opens the color picker popup instead.
Decrease size of layer and point popups that previously had color properties which need less space now.
Support shift-rightclicking color picker buttons to copy the color to the clipboard in RRGGBBAA hex format.
Support shift-leftclicking color picker buttons to paste a color from the clipboard in RGB, RGBA, RRGGBB or RRGGBBAA format with optional leading `#` or `$`.

Suggested by `@HiRavie` in https://github.com/ddnet/ddnet/pull/6743#issuecomment-1593886873, though it was easier and also looks better to me when the color picker button has exactly the same size as the other value selectors.

Compressing the data with zlib takes the majority of the time when saving a datafile. Therefore, compressing is now delayed until the `CDataFileWriter::Finish` function is called. This function is then off-loaded to another thread to make saving maps in the editor not block the rendering.
A message "Saving…" is shown in the bottom right of the editor view while a job to save a map is running in the background.
While a map is being finished in a background thread another save for the same filename cannot be initiated to prevent multiples accesses to the same file.
Closes#6762.
A copy of the map currently open in the editor is saved every 10 minutes to the `maps/auto` folder (interval configurable, see below). The automatically saved map uses the filename of the original map with an additional timestamp. Per map name 10 autosaves are kept in the `auto` folder before old autosaves will be deleted (number configurable, see below).
Add config variable `ed_autosave_interval` (0 - 240, default 10) to configure the interval in minutes at which a copy of the current editor map is automatically saved to the 'auto' folder.
Add config variable `ed_autosave_max` (0 - 1000, default 10) to configure the maximum number of autosaves that are kept per map name (0 = no limit).
Autosaving will not take place in the 5 seconds immediately after the map was last modified by the user, to avoid interrupting the user with the autosave.
This will only delay autosaving for up to 1 minute though, so autosaves are not prevented entirely, should the user continuously edit the map.
When the editor is reopened after being closed for more than 10 seconds, the autosave timer will be adjusted to compensate for the time that was not spent on editing in the editor.
When the map is saved manually by the user the autosave file is also updated, if it's outdated by at least half of the configured autosave interval. This ensures that autosaves are always available as a periodic backup of the map.
When a copy of the current map is saved, this does not update the autosave and will also no longer reset the modified state. The modified state should reflect whether changes have been made that are not saved to the current map file. As saving a copy does not update the current file, the modified state should not be reset in this case.
Closes#6693.

6560: Replace EntityEx with new netobjs r=edg-l a=trml
This is a proposal for replacing EntityEx with new netobjects, like suggested in #5860.
- Adds a new DDNetPickup that includes switch number
- a new DDNetProjectile that replaces the old one (which is renamed to DDRaceProjectile)
- includes switch number, tunezone and velocity/speed (plus a flag that can be used to send velocitiy of player projectiles with full precision)
- switch number and subtype is added to DDNetLaser (to distinguish e.g. draggers with different strength)
The pr removes EntityEx from the server, but keeps compatibility in the client.

6466: Fix rcon login when disconnecting dummy and when username used r=def- a=Robyt3
When connecting a dummy and then logging into rcon only the dummy is logged in. When disconnecting the dummy, the main client was not automatically logged in. When logging in with the main client and then connecting the dummy, the dummy was already authenticated automatically. Now the main client is also authenticated automatically when disconnecting an authenticated dummy.
This automatic authentication was also not working correctly if the login used a username, as only the password was stored. Now both username and password are stored to correctly authenticate the main or dummy client.
The stored username and password are completely cleared when disconnecting, so they are not stored in memory longer than necessary.

6461: Check if HTTP request task is aborted in completion callback r=def- a=Robyt3
It's possible for the HTTP request task to be aborted after the curl request has finished, so the returned `State` will be `HTTP_DONE` but `m_Abort` is `true`. The `State` never changes to `HTTP_ABORTED`, because the progress callback is not called after the HTTP request has completed.
This causes the client to crash when a skin download is aborted after the HTTP request finished but before the completion callback is called.
This is fixed by checking if `m_Abort` is `true` and setting the `State` to `HTTP_ABORTED` at the beginning of the completion callback.

6295: Implement FIFO on Windows using Named Pipes r=def- a=Robyt3
Reimplement the Linux FIFO file server and client controls on Windows by using Named Pipes.
The DDNet server/client acts as a named pipe server and receives messages.
Messages can be posted to the named pipe server by connecting to it as a client.
The named pipe client can for instance be controlled from the command line with PowerShell.
The PowerShell script `scripts/send_named_pipe.ps1` is added for this purpose.
For example the PowerShell command `./send_named_pipe.ps1 "testpipe" "echo a"` sends the command `echo a` to the pipe named `testpipe`.
Multiple commands can be sent at the same time by separating them with semicolons or newlines.

6284: Ensure integer wrapping instead of preventing overflow/underflow r=heinrich5991 a=Robyt3
As the integer overflow/underflow in `UndiffItem` can happen during normal gameplay, we should in this case neither ignore the snapshot delta nor show an error message.
Instead of depending on the particular compiler doing integer wrapping, when integer overflows or underflows occur, we make it part of the design, by casting to `unsigned`, which ensures that integer wrapping is being used.

This fixes issues that prevented vanilla 0.6.5 clients from joining DDNet servers with `sv_vanilla_antispoof 1` (closes#2074).
The dummy map was not valid. The size of the tiles and game layers was calculated incorrectly. The last member variable included in `CMapItemLayerTilemap` version 2 should be `m_Data`. Previously only the size of the member `m_aName` was subtracted from the total size, which was resulting in an incorrect item size, as the size of the following 5 members also needs to be subtracted.
The handshake messages were packed incorrectly. The message ID and the system flag were not added to the six packers that are passed to `SendMsgs`. The lines that are removed in this function seemed to assume that the message ID was already added but not packed, which was no longer the case. Presumable at some point `CMsgPacker` was changed without adapting the vanilla antispoof feature. Now, the message ID and system flag are properly packed when initially creating the message packers.
The `dummy_map` tool is improved to also print the generated map file's hashes and data as a C style array, so the data can immediately be copied to `network_server.cpp`.
As the integer overflow/underflow in `UndiffItem` can happen during normal gameplay, we should in this case neither ignore the snapshot delta nor show an error message.
Instead of depending on the particular compiler doing integer wrapping, when integer overflows or underflows occur, we make it part of the design, by casting to `unsigned`, which ensures that integer wrapping is being used.
One case was a ddnet.tw UUID's string being changed (but the UUID was
not), and the other case is a ddnet.tw UUID's string being changed in
one place but not in another in documentation.
Fixes the commit c479230d71.
CC #5312
Use a different error code for every return statement, so it's easier to determine why unpacking a delta failed.
The codes are grouped by the first digit of the error code:
- `-1xx`: not enough data to read
- `-2xx`: value is invalid
- `-3xx`: could not build snapshot item

When the demo recording is not stopped properly (e.g. client crashes during recording), the timeline markers and the demo length are not updated.
The length is always set to zero when starting the recording, but uninitialized memory is written for the timeline markers, which causes these demos to likely show the maximum number of markers with some markers possibly being outside the ticks that the demo contains.
This is fixed by initially setting all timeline marker data to zero when starting the recording.
The include of `base/system.h` in `src/engine/shared/protocol.h` is not required and only used transitively in `teamscore.h` for `dbg_assert`.
To avoid adding back the include in `teamscore.h`, the function definitions are moved to the cpp file. Both definitions are moved for consistency.

Instead of using hardcoded tick offsets, use the current/previous/next tick values from the demo info.
This fixes seeking the next tick not working for demos where the difference between the current and the next tick was greater than 3.
Each time the client disconnected or stopped a demo, it tried to delete the previous temporary replay file, which causes an error message "could not delete file" to be shown in the console.
This is prevented by clearing the current filename of the demo recorder after deleting the file.
When slicing a demo, also copy the demo markers that are within the sliced segment to the new demo.
This also fixes timeline markers not being added to replay demos, as the replay demos are always created by slicing.

6035: Fix various issues reported by cppcheck static analyser r=def- a=Robyt3
After generating `compile_commands.json` with cmake, I ran [cppcheck](https://cppcheck.sourceforge.io/) like this:
```
cppcheck --project=compile_commands.json -DWIN64 --suppressions-list=cppcheck.supp --enable=all 2>cppcheck.log
```
With these suppressions in `cppcheck.supp`:
```
cstyleCast

noConstructor
uninitMemberVar
uninitMemberVarPrivate
uninitDerivedMemberVar
uninitStructMember

Many of these occur too often or are false positives.
Here is a list of all remaining non-suppressed issues reported by cppcheck: [cppcheck.log](https://github.com/ddnet/ddnet/files/9997663/cppcheck.log)
And here is a list of all remaining issues including the suppressed ones: [cppcheck_all.log](https://github.com/ddnet/ddnet/files/9997662/cppcheck_all.log)
I couldn't get cppcheck's command line argument to ignore the external folders to work correctly, so I manually removed those entries from the files.

According to cppcheck's `unreadVariable` error.
When stored commands (`CFGFLAG_STORE`) were executed with `CConsole::StoreCommands(false)`, the associated chained commands were not properly executed, if they were chained after the command has been stored (e.g. in `CMenus::OnInit`).
Storing the command saves the current callback and userdata, which were overridden by the chain callback and userdata, but the stored callback and userdata were not updated.
This is fixed by storing a pointer to the command itself, which will be updated when it is chained.
From teeworlds/teeworlds#2572.
The client crashes when trying to unpack a packet that has the sixup flag set, as `CNetClient` does not pass pointers for the output parameters `pSecurityToken` and `pResponseToken` to `CNetBase::UnpackPacket`.
Since the client does not handle sixup packets, checks are added to return an error and ignore the packet instead of crashing due to a null pointer access.
This was found by fuzzing the data returned by `net_udp_recv` with radamsa.

Demo seeking for percent positions and relative time was choppy, when the first and last ticks of the demo are very large but close together (e.g. with 1308908156 to 1308905658, which are close to integer limit).
During the calculation of `WantedTick` both operands were promoted to `float`s, which caused the information of the smaller operand, i.e. the seeked percentage or relative time, to be mostly lost, so seeking was very inaccurate.
This is fixed by rounding the `float` operand to `int` before adding it to another `int`.
The types are translated to `TYPE_ALL`/`TYPE_SAVE` respectively if a given path is relative and to `TYPE_ABSOLUTE` if a path is absolute.
These types are only supported with the `OpenFile`, `ReadFile`, `ReadFileStr` and `GetCompletePath` methods.
This reduces duplicate code when calling the methods.
5599: Add support for Rust code in DDNet r=def- a=heinrich5991
The glue is done using the [cxx crate](https://cxx.rs/) on the Rust side.
As a proof-of-concept, only a small console command (`rust_version`) printing the currently used Rust version was added.
You can generate and open the Rust documentation using `DDNET_TEST_NO_LINK=1 cargo doc --open`.
You can run the Rust tests using `cmake --build <build dir> --target run_rust_tests`, they're automatically included in the `run_tests` target as well.
Rust tests don't work on Windows in debug mode on Windows because Rust cannot currently link with the debug version of the C stdlib on Windows: https://github.com/rust-lang/rust/issues/39016.

This function searches in all subfolder of the given folder and fills the given `std::vector` with all files with the given filename.
A `std::set` is used to prevent duplicate entries when a file with the same path is present in multiple storage locations. In that case we only need the path once, as we only use it against the highest priority storage location anyway.
