The `CTextCursor::m_LineCount` variable is only updated after the cursor is rendered. For calculating the selection quads we need to check `LineCount` instead, which is updated while the cursor is being rendered. Regression from #7733.
Free up space for up to three more server browser tabs of the same size (on 5:4 resolutions), i.e. tabs for configurable communities.
Remove the additional server browser icon tab on the right side. Remove the purely visual Demo and News tabs which were only shown when the respective page is already active. Instead, always show all server browser tabs when offline.
The `IClient::Disconnect` function is always called at the beginning of the `IClient::Connect` function. The `IClient::Disconnect` function calls `IClient::DisconnectWithReason`, if the client is not already offline, which performs cleanup of temporary commands and demo recorders already, so the same cleanup in the `Connect` function is unnecessary. An assertion is added to ensure that the client was properly disconnected before connecting. Connecting while the client is already quitting or restarting is now prevented, as the client state cannot be changed once set to quitting or restarting.
By adding `CDataFileWriter::ECompressionLevel` to replace usage of zlib internal compression levels in the `CDataFileWriter` API.
Use `std::numeric_limits<int>::max()` instead of `INT_MAX` in one case where the latter was only declared by the transitive zlib include. The `limits` header is already included and its use is more fitting for C++ code.
The server community was only initialized when receiving server info. This caused servers for which no server info is received to be hidden when using the community filter. Now the community filter also works correctly for servers for which no ordinary server info is received, by initializing the community already when adding server entries to the list.
Closes#7776.
Adapt the `CDataFileReader::GetItem` function so it optionally also returns a `CUuid` for UUID-based map items, including for items with unknown UUIDs where the item type will be `-1`. Adapt the `CDataFileWriter::AddItem` function so it optionally also accepts a `CUuid` which will be used if the item type is `-1`.
The additional checks for invalid map item types in the map tools are removed again and instead the new UUID parameters are used so map items with unknown UUIDs are written back to maps correctly.
Closes#7701.
Add separate `IGraphics::LoadTextureRawMove` function with non-`const` `void *pData` argument in addition to existing `LoadTextureRaw` function with `const void *pData` argument. The former function takes ownership of the data and avoids copying the texture data into an additional buffer, if the texture data is already in RGBA format. Non-RGBA texture data always needs to be converted and therefore also copied.
The `LoadTextureRaw` function is split into smaller functions to share common code with the `LoadTextureRawMove` function. Alternatively to this, a flag `TEXLOAD_MOVE_DATA` could have been added to the existing `LoadTextureRaw` function, which would have required the use of `const_cast` to free the texture data.
Unset the assertion handler before shutting down the kernel (including graphics) and client. Otherwise the assertion handler itself crashes when assertion errors happen after the graphics/client have been destroyed.
Add color palette with up to 8 colors to editor toolbar. The palette colors work like regular color picker buttons, so they open a color picker popup on click and the value can be copied and pasted with Ctrl+Right click and Ctrl+Left click respectively. Less palette colors are shown when not enough space is available (with 5:4 resolutions).
Add color pipette which allows selecting any color displayed on the screen. Selecting a color with the pipette adds the new color to the palette and shifts the other colors to the right. The selected color is also copied to the clipboard immediately. The hotkey Ctrl+Shift+C is added to toggle the color pipette, which allows using the color pipette in popups and dialogs.
The implement this, the function `IGraphics::ReadPixel` and the command `SCommand_TrySwapAndReadPixel` are added to read a specified pixel's color from the backbuffer. Like the screenshot command, this command also requires a swap operation to be performed before the correct pixel color can be read with the Vulkan backend. The `ReadPixel` function therefore accepts a pointer to a `ColorRGBA` that will be filled after the next swap operation.
Closes#7430.
Replace linear search for free sample index with free list. This brings sound sample index allocation down to constant complexity independent of the number of allocated sounds. On average the time to allocate sound samples is reduced by around 75% (843µs down to 223µs). For perspective, the time to load all default sounds on client launch is reduced by around 15ms (although this does not significantly affect launch time due to threaded loading).
The lock needs to be owned when accessing the sound voices. Calling `IsPlaying` is redundant, as the loops effectively check whether the sample is playing.
Add dropdown menus for changing animation and grid settings (i.e. animation speed and grid size) instead of conditionally showing more buttons for this directly in the menu bar. This frees up space in the menu bar, which is currently full on 5:4 resolutions.
The icons previously used for the default animation/grid buttons are now used for the main buttons that toggle animation/grid instead of using text.
Support setting lower animation speeds with the plus and minus buttons by adjusting the step size when the animation speed is low.
Support setting arbitrary animation speed by text input.
Render one quad for each line of the text selection instead of rendering one quad per selected character.
This increases the average FPS when the console is open and all text is selected by around 10% (from around 849 to around 943 FPS) (on my machine, in release mode).
When normalizing color components in the engine graphics, round the components to the nearest integer instead of rounding down. Otherwise the color that is rendered in color pickers may be off by 1 in any of its RGB components from the color that the color picker displays as text (hex string and individual components). The slightly incorrect color can be confirmed by creating a screenshot or otherwise reading the backbuffer (planned editor pipette feature).
This should not change map rendering, since maps already store quantized RGBA values on which the rounding mode should have no effect. It may however slightly change appearance of colors in all other places (at most +1 in every RGB component).
According to the Vulkan specification, the struct `VkBufferImageCopy` is used only for `vkCmdCopyBufferToImage` and `vkCmdCopyImageToBuffer`. The variable `Region` is only initialized but not passed to either of those functions.
- Use existing functions from `system.h`
- Use sorting from `<algorithm>`
- Don't recall `ListDirectory` for every removal, which caused the client to hang previously with a lot of files.
Consider line spacing to belong to the previous line when calculating and rendering text selection. Instead of handling spacing between entries separately in the console, also include line spacing for the last line in the height calculation. Pixel align the line spacing in addition to the font size, as previously some gaps between the entries were larger than others due to missing pixel alignment. This allows rendering the text selection in the console smoothly without any gaps between the console entries/lines.
Closes#7617.
Reduce duplicate code.
Replace `clampf` function with `NormalizeColorComponent` function that convert color component from `float` to `unsigned char`.
Use `size_t` instead of `int`.
Add a proper kernel interface `INotifications` for the notifications component instead of using a C style interface.
Add parameter for the application name when initializing notifications to avoid hardcoding the application name.
The implementation for macOS is kept in Objective-C and a TODO is added, as the API we are currently using appears to be deprecated.

Prevent potential dead lock when using `/map` chat command in combination with Teehistorian. Closes#7619. I could not reproduce the issue on Windows though.
This also means resetting game settings should actually be efficient now, because it only involves iterating over all game settings and directly resetting their value.
Previously, only one buffer was allocated to store each snapshot holder structure, the snapshot data and alternative snapshot data. This prevents tools like ASAN from detecting some invalid accesses, e.g. to the snapshot holder structure by underflowing the snapshot data pointer. Now three separate allocations are used instead. This hopefully helps debugging #2677.
We support little and big endian but not PDP endian (Middle-endian).
Define endianness as string `CONF_ARCH_ENDIAN_STRING` to avoid conditional compilation when printing endianness.
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.
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.
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.
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.
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.
