Immediately cancel new HTTP requests instead of enqueuing them when already shutting down `CHttp`. Otherwise, `CChooseMaster` may wait forever for HTTP requests to be completed while the client is shutting down, if `CHttp` was shutdown while `CChooseMaster` is not waiting for an existing HTTP request.
Not directly caused by #7962, but it made it more likely to happen.
Closes#7980.
Instead of sending the message from the first client which is not ingame, choose the first client which is fully empty, to make it less likely that the message is sent from a currently connecting client.
Add a country "none" with tee flag (code `-1`) and a type "None" for all servers without community.
Previously, the country and type for these servers was unset and their handling special-cased, so any non-empty country/type filter would exclude servers without country/type information. Now individual countries/types can be excluded without also excluding all servers without community.
Closes#7961.
Shutdown `CHttp`, i.e. abort all HTTP requests, as early as possible when quitting/restarting the client, after the config has been saved but before shutting down the gameclient. Previously, this was delayed until the engine shutdown, so the requests would often finish entirely instead of being aborted by the callback.
Previously, HTTP requests being aborted due to `CHttp` shutting down were considered `EHttpState::ERROR`, which sometimes causes deadlocks during engine shutdown or destruction of `CHttp`. The state is now set to `ABORTED` by passing `CURLE_ABORTED_BY_CALLBACK` to `OnCompletionInternal`. The otherwise unused handling of internal errors is removed.
Previously, it was assumed `ResultJson` would return `nullptr` for HTTP requests which have been aborted or failed with an error, which would trigger the newly added assertion error "Request not done".
Instead of preventing the client from quitting/restarting while a warning is shown in the menus, add warnings that should be shown after quitting/restarting (i.e. the warning when the config could not be saved) to a separate list and show these warnings using an OS message box after the client has been closed. Otherwise, the client is prevented from closing if a warning is shown without being automatically hidden, which causes the client to hang indefinitely in the CI.
The message boxes for warnings must be shown after the client has already been completely shutdown, otherwise the regular shutdown with the Vulkan backend crashes because showing the message box has already partially deinitialized the backend.
The quitting/restarting client state is now checked after updating the FIFO component, so quitting/restarting initiated via FIFO is effective immediately, although this should have little effect in practice.
For completeness, a log message is added also for the case that the config was saved successfully.
The GitHub CI seems to automatically confirm/disable OS message boxes, so they should not block workflows.
Add assertions to ensure that the HTTP request result data and SHA256 are available when getting them instead of returning `nullptr` and `SHA256_ZEROED` when they are not.
Rename `CHttpRequest::Sha256` function to `ResultSha256`.
Because of incorrect index/size math, two favorite communities were removed when exceeding the maximum number of three favorite communities instead of only one. The check can be simplified because the maximum number of favorite communities can never be exceeded, so at most the first element needs to be removed from the vector.
Closes#7935.
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.
Support adding up to three communities as favorites in the server browser. Favorites can be changed with favorite buttons which are shown in the community filter on the Internet and Favorites tabs. The commands `add_favorite_community` and `remove_favorite_community` are added to change the favorite communities via the console and for saving the favorite communities to the config file. For the favorite communities, additional tabs using the communities' icons are shown in the server browser next to the Internet, LAN and Favorites tabs. Each community tab shows only the servers from the respective community, hence the community filters UI is not shown on the community tabs but only on the Internet and Favorites tabs. The country and type filters on community tabs cover only the countries and types from the respective community. Favorite communities are added from left to right. When more than three favorite communities are added, the oldest (leftmost) favorite community will be removed from the list.
When starting the client for the first time, i.e. with `cl_show_welcome 1`, the DDNet tab will be created as the only favorite community and selected initially. The community, country and type filters are unset when starting for the first time, so the Internet tab now shows all servers per default.
When starting with a `ui_page` for a favorite community that is not configured, the page is reset to the Internet tab. This also affects those who upgrade from versions with the old DDNet and KoG tabs. The server browser is now also correctly updated when changing `ui_page` via the console.
Track country and type filters for every community separately, to avoid filters resetting when switching between community tabs or changing the community filter. The commands `add_excluded_community`, `remove_excluded_community`, `add_excluded_country`, `remove_excluded_country`, `add_excluded_type` and `remove_excluded_type` are added to change the exclusion filters via the console and for saving the exclusion filters to the config file.
Render community filters above the toolbox (filter, info and friends) tabs when on the Internet and Favorites tab, so this setting is more visible and can be changed also when the other toolbox tabs are selected.
Add icon for the none community, based on the tee country flag color. This icon is hard-coded in the client, as the none community also is, so fetching the icon from the server would be inconvenient. Load community icons already when rendering the menu instead of only when rendering the server browser, so the icons are immediately available when using the start menu.
Find tutorial server by searching for community type "Tutorial" instead of searching for "(Tutorial)" in the server name.
Avoid cleaning favorite communities and filters when there are no communities, i.e. when the DDNet info failed to be loaded or does not contain any communities, to avoid losing all favorite communities and filters in this case.
Closes#7774.
When empty PNG files are loaded, the `std::vector` for the file contents is resized to size 0, which results in undefined behavior when it is accessed with `front`.
When `io_tell` fails, i.e. returns `-1`, this was incorrectly cast to an `unsigned` and therefore caused a very large allocation and potentially crashes due to lack of memory.
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.
