Avoid many writes to disk each time the DDNet info is downloaded, i.e. each time the refresh button is pressed in the server browser, by first loading the DDNet info into memory and only writing it to disk when it differs from the current DDNet info based on the SHA256 hash.
The SHA256 is now also used to track whether the DDNet info was modified for the community filters and icons instead of using the current time for this purpose.
Closes#3941.
Initialize the HTTP client (start the HTTP thread) after initializing the network client instead of during the client interface construction. This ensures that config variables have been loaded already and the log output level is set correctly. This also means all library initialization log messages appear together in one block when starting the client.
Show an error message box and stop launching when the HTTP client could not be initialized, instead of launching but not being able to perform any HTTP requests, which causes bug reports about the serverlist being empty.
Both console and chat commands are sent to clients dynamically with respective messages, so the static lists of commands were only used for servers not making use of these messages. Instead of assuming potentially incorrect console and chat commands on those servers, the lists will now be empty for those servers.
Move the command registration from the `ddracecommands.h` and `ddracechat.h` header files to the `CGameContext::RegisterDDRaceCommands` and `CGameContext::RegisterChatCommands` functions and delete the header files. The `CHAT_COMMAND` and `CONSOLE_COMMAND` macros are removed, because they only add unnecessary indirection now. The strings `CHAT_COMMAND` and `CONSOLE_COMMAND` are simply replaced with `Console()->Register` and semicolons are added at the end of the lines.
Closes#7665.
Use error log level for error messages. Use info log level explicitly instead of using `dbg_msg`.
Log time taken for initialization in trace level message.
Add parameter to `shell_execute` to either start the process in the foreground or background on Windows. Previously, all processes were started in the background, because this is desired when starting the server from the client. However, this causes the graphics initialization to fail when restarting the client after updating or with the `restart` command when using Vulkan with windowed and windowed fullscreen mode.
Closes#6578.
The `bool AllowResizing` parameter is only passed to other `SetWindowParams` functions but never used in the end, as whether or not resizing is allowed is separately determined based on the value of the `int FullscreenMode` parameter.
To simplify the usage of the demo recorder, parameters are added to the `IDemoRecorder::Stop` function to control whether the demo file is removed or renamed when stopping the recording.
Ensure demo files of the replay recorder are always removed (except on crashes). The temporary replay demos were previously not removed when being disconnected from a server.
Fix auto demos being stopped and restarted when enabling replays in the settings menu. Now only the replay recorder is stopped/started when necessary.
Fix replay recorder being restarted when setting `cl_replay` variable with console without changing the value.
Remove unnecessary `CClient::m_ButtonRender` variable. Demo rendering is already stopped correctly when reaching the end of the demo without this additional variable.
Remove unused `CDemoRecorder::m_pMapData` variable.
Store X value (time) for all graph entries in addition to the Y value (FPS, prediction margin etc.). The `CGraph::Add` function adds values to the graph at the current time. The `CGraph::InsertAt` function allows specifying arbitrary X values, as long as the values are inserted in increasing order.
The entries are kept in a ringbuffer and old entries are recycled when it's full. The size of the ringbuffer is configurable for each graph, as the FPS graph needs significantly more buffer because values are added more often.
The scrolling speed of the graphs is fixed by specifying the maximum size of the window of values which should be displayed. For this purpose, a parameter is added to the `CGraph::Scale` function to specify the size of the window which should be rendered in the `CGraph::Render` function. For the FPS graph only the last second is rendered, so small spikes are still noticeable. For prediction and gametime margin graphs the last five seconds are rendered, which should result in a similar scrolling speed as before this change. The debug tuning graph is a special case, where the X values set manually and fixed to 0-127, same as before, instead of being based on the current time.
The graph rendering is made much more efficient by precalculating when the vertex colors need to be updated, to avoid all unnecessary calls to `SetColorVertex`. Additionally, line items are bundled together in an array to avoid calling `LinesDraw` for every individual line item.
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.
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 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.
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.
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 `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.
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.
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.
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`.
There is no need to limit the length of server password, rcon username, rcon password and rcon commands when packing them into their respective messages. The source buffers for these strings are already limited in length and the message packer ensures that the maximum packet size is not exceeded.
Add parameter `int Conn` to `SendInfo` and `SendReady` functions and use existing `SendEnterGame` function to reduce duplicate code for sending the same messages for main and dummy connections.
