On Windows the function `setsockopt` does not set `errno` on errors but instead `WSAGetLastError` must be used. This is encapsulated in the `net_errno` function.
The variable `Id` is translated for old clients and is not guranteed to
be the real id. While `m_ClientID` is the real ID. That can also be used
to index the CServer::m_aClients[] array to get the authed state.

Which is using ID 0 as index in the m_aClients array but only ID 63 was
ever initialized.
The `LoadMapSearch` function returns an error message or `nullptr` on success but the condition was incorrectly changed in #7580 so the opposite was checked instead.
Closes#7597.
Setting a vote timeout longer than 60 seconds with `sv_vote_time` caused the vote network messages to be discarded with the error message `weird message 'Sv_VoteSet' (15), failed on 'm_Timeout'` by the client, as the protocol did not allow longer vote timeouts.
This changes the protocol so the vote timeout can be any positive integer although for now the maximum `sv_vote_time` value is changed back to 60 again to preserve compatibility with old clients.
Closes#7583.
The invalid sound index is `-1` but the check in the editor for the sound preview assumed it was `0`. We should use a type-safe wrapper to avoid this in the future, like for texture handles.
The popup menu render function can open/close other popups, which may resize the vector of popup menus and thus invalidate the current popup menu variable before the popup is closed. We therefore store the popup UI element ID in a separate variable to avoid the access to the potentially invalidated popup menu variable after the popup menu is rendered.
Also prevent invalidated popup menu from being rendered for one frame after it is closed by clicking outside.
Closes#7565.
Support registering arbitrary number of interfaces with `IKernel` instead at most 32.
Assert when incorrect arguments are passed to `IKernel` functions instead of returning a `bool`, which was not being handled in all cases. These functions are not expected to fail expect on programming errors.
Consistently order and format creation and registration of kernel interfaces in client and server.
Additionally, ensure snapshots are cleared and dummy is disconnected when disconnecting programatically with `DisconnectWithReason`.
Add `NETADDR_ZEROED` and `UUID_ZEROED` for more convenient initialization without using `mem_zero`.
Add stricter error handling when converting between UTF-16 (wide characters) and UTF-8 (multi-byte) on Windows.
The `windows_wide_to_utf8` function now returns an `std::optional`, which will be empty if the argument contains invalid UTF-16. Files/folders with names containing invalid UTF-16 are now ignored on Windows. It was previously not possible to use these files either, as converting their names to UTF-8 changed the invalid codepoints to unicode replacement characters.
The `windows_utf8_to_wide` function now fails with an assertion error if the argument contains invalid UTF-8, as this should never happen.
Closes#7486.
Add `CHttpRequest::ExpectSha256` function to specify expected SHA256 for HTTP downloads. If the download completes with a different SHA256 hash than expected, then the download fails and the file is deleted.
Closes#7485.
Move all code for handling of config variables from console to config manager. The console no longer depends on the config manager, instead the config manager now depends on the console.
Add `struct`s to manage config variables of different types (int, color and string). The config manager now keeps a list of all config variables, so usage of the preprocessor can be avoided except for code to initially create all config variables. Additionally, a separate list of just the game config variables (config variables with `CFGFLAG_GAME`) is kept to optimize the `ResetGameSettings` function, as this function is called whenever connecting to a server and should be fast. Previously, this function was even less efficient because it preformed a linear search for every individual game config variable to find the respective command data.
Move console commands that opperate only on config variables (`reset`, `toggle` and `+toggle`) to config manager. Ensure that these commands only opperate on the desired config variables (client or server, respectively) by checking `IConsole::FlagMask`.
Add `IConfigManager::SetReadOnly` function to set/unset config variables as read-only instead of manually overriding the command handlers for the `sv_rescue` and `sv_test_cmds` config variables. This also fixes that read-only config variables could still be changed by using the `reset` command. A console message is now printed when trying to change a read-only config variable. Removing the special handling for these two config variables is additionally useful so the console does not need to keep a pointer to config values and manager.
Use a `CHeap` for the config variables, their help texts and the previous values of string config variables to avoid many separate allocations as well usage of static variables. Also use the heap to store the unknown commands instead of using `std::string`s.
Properly trigger command chain when resetting config variables with the `reset` command and when resetting game settings on map loading. Closes#7461.
Format default value for color variables as RGB/RGBA hex with dollar sign prefix. Closes#5523.
Add log message when using `reset` with a variable that does not exist. Use `log_error` instead of `dbg_msg` when saving config file fails.
Support unlimited number of config save callbacks instead of at most 16. The code also becomes more readable by using an `std::vector` instead of a fixed-size array and a separate num variable.
Consistently name `MACRO_CONFIG_*` parameters when declaring the macros.
Add `IConsole::CMDLINE_LENGTH` constant to represent the maximum length of the console input and thereby reduce usage of magic numbers for buffer sizes.
Add a templated `CHeap::Allocate` function to simplify memory allocation of objects using `CHeap`. The function uses perfect forwarding to construct objects with the specified arguments.
Apply the name bans system also to player clans, meaning players joining with banned clan names are kicked and changing the clan to a banned name while ingame has no effect.
Additionally, trim UTF-8 whitespace from beginning and end of clan. This was already done for player names but not for clans.
Closes#7516.
Unify all code for name bans in new class `CNameBans` in the existing `name_ban.cpp/h` files. The previously global function `IsNameBanned` is now the member function `CNameBans::IsBanned`. The existing name ban tests are extended for the `CNameBans` class.
Move `CNameBan` constructor definition to source file to avoid including `system.h` in the header file. Use `bool` instead of `int` for `m_IsSubstring`. Reorder `CNameBan` constructor arguments and remove unnecessary default value.
The contents of `variables.h` are moved to `config_variables.h` instead of being included with the preprocessor. The file `variables.h` is removed, so all config variables can be found in a single file instead of being spread over two files without any clear structure. The original declaration order of config variables is preserved. The unnecessary header guard `GAME_VARIABLES_H` from `variables.h` is removed, as the comment `// This file can be included several times.` already serves the same purpose of silencing the header guard check.
A comment is added at the end of `config_variables.h` to mark the location where modders should ideally declare all of their own config variables to avoid merge conflicts with us in the future.
Closes#7472.
Interfaces should not have member variables, so the variable is moved to `CConsole`. Only a getter `IConsole::Cheated` is added because the cheated state of the console is never reset.
So other interfaces/components can check which console commands are active. In particular this will be used to refactor the config manager. The respective setter function already exists.
After you issue a command in the client console or rcon, the command
will first be printed to the console prefixed with a '>' symbol.
Cherry-pick of https://github.com/teeworlds/teeworlds/pull/3185
Due to swapped `str_copy` arguments, the old value for string game variables was being overridden by the current value instead of the other way around in `CConsole::ResetGameSettings`.
There are currently no string game settings affected by this.
Handling color settings the same as int settings in `CConsole::ResetGameSettings` is not correct, as this causes the color variable data to be cast to int variable data.
There are currently no color game settings affected by this.
Call expected server callback functions to simulate clients dynamically connecting and disconnecting when changing the `dbg_dummies` variable. This makes the debug dummies more useful for debugging. Previously, the debug dummies were considered invalid clients, whereas they are now considered to be ingame, so they should behave mostly like real clients being connected to the server. The debug dummies also have correct client names now, e.g. "Debug dummy 42".
The game server code is cleaned up by moving all special handling for debug dummies to the engine server function `CServer::UpdateDebugDummies`.
The left/right direction inputs for debug dummies are now properly added to the client input array, so their input handling should be consistent with normal clients, which fixes some inconsistent prediction with debug dummies.
Greyscale images with alpha channel (i.e. channel count = 2) were incorrectly handled as RGBA images, causing the client to crash when loading such images. Now the images can successfully be loaded with the image loader, but the client still only supports loading RGB and RGBA images like before.
The image data is freed when the image format is unsupported, but `CImageInfo::m_pData` would still point to the freed memory, so double-frees were possible.
Gets rid of more CGameControllerDDRace casts.
Those did not show up during compile time only during runtime
of another active controller when asan is active.
Also update server browser filtering/sorting when changing the community/country/type filter config variables with the console.
Clean the filter config variables when they are changed instead of only when the community filter is rendered.
Ensure that community/country/type filters do not exclude all allowed elements, which can happen when a previously selected community is not available anymore or when arbitrary community filter values are set with the console.
Allows to do this
```C++
for(const CPlayer *pPlayer : GameServer()->m_apPlayers)
{
if(!pPlayer)
continue;
if(!pPlayer->GetCharacter())
continue;
// your code that does not change the character state
}
```
Initialize nontrivial types with a constructor instead. Make the
compiler aware that some of our constructors are indeed trivial.
This allows `mem_zero` calls to actually always zero the memory.
Partially replaces #5690.
POD types are just memset. Other types are either destructed if not
trivial and/or constructed if not trivial. Types need to have a default
constructor.
Virtual classes can be mem_zeroed only if they already have been
constructed, otherwise it is UB.
Zeroing the entire ringbuffer memory is unnecessary and inefficient. Only the first item in the ringbuffer has to be initialized properly.
It's unlikely that existing code depends on allocated memory being zeroed, as recycled ringbuffer items where never zeroed.
Previously, the client would hang due to recursive usage of the console backlog lock when a log line is printed via the logger functions while already owning the backlog lock. This could happen when the text render causes log messages to be printed while the console backlog is rendered.
This is fixed by introducing a separate pending backlog to which new log lines are initially added and which is protected by a lock. The pending backlog entries are pumped into the normal backlog before the normal backlog is used, so accesses to the normal backlog do not need to be locked anymore. This means the console backlog lock is not owned when calling any functions that could print log messages, which should prevent the dead lock.

Also increase usage of the `GetDDRaceTeam()` method.
Instead of reimplementing it in place everywhere.
move `m_Teams` from the ddrace controller to `IGameController`
so the ddrace controller casts can go away
This will enable creating another controller instead of the ddrace
controller. Which is useful for community forks.
Also make `m_Teams` private and define a getter for it.
This makes future refactors smoother.
On Unix, the encoding of filenames is unspecified, although UTF-8 is likely used in most cases. Detecting and converting from several possible encodings to UTF-8 would be too much effort, considering that most systems already use UTF-8 per default. Therefore, any filenames which are not valid UTF-8 will be ignored when listing directories with `fs_listdir(_fileinfo)`, `fs_storage_path` will fail if the storage location is not valid UTF-8 and `fs_getcwd` will fail if the current working directory is not valid UTF-8. Paths specified in `storage.cfg` must also be valid UTF-8.
On Windows, we already ensure that all filenames are converted to UTF-8.
The check for multiple storage locations was using the base path from the previous invocation of the file dialog instead of using the new base path.
Closes#7463.
When the `CGameContext::SendChatTeam` function is used to send a chat message to all members of a DDTeam (e.g. on completed /swap chat command), it was not checked whether the target players are online but only whether they belong to the specified team according to the teams core. However, the default team for unconnected/cleared players is 0 in the teams core, which is the same for players in team 0, so chat messages were being sent to client IDs not corresponding to connected clients when chat messages where supposed to be sent to players in team 0. This was causing the server to crash with the assertion error "erroneous client id" specifically when the server is started with `sv_max_clients` being less than the default, maximum 64.
Closes#7450.
Simplify selecting envelope point colors by showing a color picker button that opens a color picker popup to change the color of the selected envelope point. The existing editbox to change only the selected channel's value is kept, as the color picker popup does not support the same precision to specify the individual color channel values.
Closes#7317.
When using ctrl+s to test the current envelope it should not activate
the scale mode. This causes unexpected envelope changes on ctrl+s based
envelope fine tuning testing.
Use `CLock` and `CLockScope` instead of `std::mutex` and add clang thread-safety analysis annotations everywhere except for usages in engine graphics and video, as those usages also involve `std::condition_variable`.
Fix lock not being unlocked on all code paths in `CFutureLogger::Log`, which is caught by the static analysis.
Replace usages of platform specific `lock_*` functions with `std::mutex` through the wrapper class `CLock`. Move lock classes to `base/lock.h`.
The `CLock` wrapper class is only necessary because the clang thread-safety attributes are not available for `std::mutex` except when explicitly using libc++.
Round to nearest integer instead of truncating in `f2fx` to ensure correct round-trip with `fx2f`.
Add test to ensure correct round-trip with maximum `0.0005f` absolute error.
After the error message popup is shown for graphics assertions, the client window was destroyed but the process was not terminated properly. Now the graphics assertion error is handled like a normal assertion error, as those are also shown in an error message popup and correctly cause the client to break into the debugger or terminate.
However, calling `dbg_assert` while already owning the lock that `WaitForIdle` waits on will cause a deadlock, so error handling must be delayed until after the lock is released.
The buffer size for assertion messages is increased, as it was not sufficient for some graphics assertions.
The `ICommandProcessor::GetError` and `ICommandProcessor::GetWarning` functions are marked as `const`.
Add buttons for selecting the color mode (RGBA, HSVA, HSLA) in color picker popups in menu and editor. Previously, the color picker popups always showed the color components in HSVA. Now the mode can be switched so the components are shown in either RGBA or HSLA. The hex color code is always RGBA, same as before.
In the editor, the RGBA mode is used per default, to prevent any loss of information due to color conversions, as the map format stores RGBA values. In the menus, the HSVA mode is the default, same as before, although the config actually stores HSLA values.
The HSVA color picker controls (1D slider for hue, 2D picker for saturation and value) are still shown for all modes.
As many color conversions as possible are avoided by only converting between color formats when necessary. Switching between color modes should not change the selected color. Changing the RGBA hex value in the editor will set the exact value also when another color mode is selected. However, changing the color with the other controls in HSVA/HSLA mode will cause a conversion and possible loss of information. The conversion directly from RGBA to HSVA and vice versa is also explicitly avoided, as this internally converts to HSLA first, which is done separately already.
Closes#7409.
Previously, the client would crash with an assertion when writing more than 1024 items, 1024 data items or 64 extended item types to a map file. This arbitrary limitation is removed by using `std::vector`s, so much larger maps can be written. This was only a limitation when writing map files. Old clients can correctly read the map files having more items/data but will crash when the map is saved in the editor.
Remove the DDNet and KoG tabs and replace them with a community filter, which works like the country and type filters. Community information (ID, name, icon SHA256, countries, types, servers, ranked maps) is loaded dynamically from the DDNet info json.
The official checkmark icon is replaced with community icons. The icons are downloaded to the `communityicons` folder in the config directory from a URL specified in the DDNet info json. The icons are only re-downloaded when their SHA256 has changed.
Per default, the Internet tab with all communities is selected. When starting the client for the first time, only the DDNet community is selected. The community, country and type filters can also be used on the Favorites tab now. The LAN tab remains unchanged.
The country and type filters are refactored. Previously, using these filters changed the total number of servers and players that were displayed, as the filter was implemented as a separate step. Now the community, country and type filters work like the other browser filters. This also has the benefit that the server list and DDNet info json are not reloaded each time these filters are changed, as updating the local filtering/sorting is enough now.
The check for finished maps is made more efficient by using an `std::unordered_set` instead of linear search.
Closes#5654.
Some calls to `LoadTextureRaw` where passing the image format also in place of the texture load flags. Since the image format would be RGBA most of the time, this was interpreted as the flag `IGraphics::TEXLOAD_NOMIPMAPS` causing various textures (all sprites textures, assets when shown in menus, menu images, menu theme icons) to be loaded without mipmaps.
This is fixed by passing `0` as the texture load flags and by replacing uses of `LoadPNG` and `LoadTextureRaw` with `LoadTexture`.
Rename `InvalidTexture` to `NullTexture` to avoid confusion because the null texture is not invalid. The function `CTextureHandle::IsNullTexture` is added to make it easier to check the result of using `IGraphics::LoadTexture`, which returns the null texture on error instead of an invalid texture handle. An assertion is added to ensure that `IsNullTexture` works correctly.
The handle returned by `LoadTextureRaw` is either valid or invalid (i.e. `-1`) but never the invalid texture itself.
Additionally, ensure that the `LoadTexture` function returns the invalid texture also when `LoadTextureRaw` fails.
Load theme icons individually for all themes that have been loaded instead of doing a separate scan of the `themes` folder for the icons.
Fix screen occasionally flashing black when opening the general settings. This was caused by `UpdateAndSwap` randomly being called when theme loading takes longer than 1/60 seconds, which sometimes happens on the first start of the client after rebooting the machine. Now the loading popup is correctly rendered when theme loading takes longer than 500ms, which is consistent with the behavior when loading other files.
Minor improvements to log messages.
Using `CMenus::PopupWarning` will immediately set the popup and override the current warning, which can hide warnings when multiple are shown at the same time. Now all warnings are added to the queue with `IClient::AddWarning`.
Add assertions to prevent map items and data that are too large to be represented by the map format from being written to maps. Additionally, ensure that the size of the whole map file is not too large to be represented by the map header.
Prevent `malloc` of size 0, which is implementation defined and should be avoided, when adding items without data, which happens for example when adding an empty array of envelope points.
Show a warning popup when a map image or sound cannot be loaded for any reason. Only one generic warning popup is shown for images and sounds individually.
The image name is only required for external images. For embedded images it was only used in log messages. This fixes rendering with various maps that have embedded images with invalid names.
Parallax Zoom improves the appearance of maps visually when zooming.
Contrary to initial tests, it does not interfere with certain map
locations such as the shop on the map Timeshop.
The default value appears to be correct for all existing maps.
The value in the map file is non-trivial to manage, and provides little
benefit. See https://github.com/ddnet/ddnet/issues/6196 for further
discussion.
Limit number of sounds being loaded in the client to 64, instead of writing sample indices out of bounds.
Check if sound indices are out of bounds. It was only checked whether the sound index is -1 but no other bounds checking was performed.
Check if image indices are out of bounds. It was not checked for all negative image indices, only -1 was considered.
Add popup message in the editor when trying to add more than 64 sounds, same as for images.
Limit number of images in `map_convert_07` tool, instead of writing out of bounds.
Add easter, halloween and xmas to `enum ETimeSeason` and `time_season` function. This unifies the logic for detecting these events and seasons in one function. This allows adding support for special easter, halloween and xmas theme maps in the future. The `localtime` function is not used outside `system.c` anymore. The code for detecting easter is taken from upstream.
