Use config manager to reset `ui_page` to the default, instead of using `CMenus::PAGE_DDNET` directly (which is the default).
Check current type of serverbrowser instead of checking the current `ui_page` against `CMenus::PAGE_DDNET` and `CMenus::PAGE_KOG`.
Using `dbg_stress 1` now only does the following (in debug build):
- Randomly send inputs.
- Randomly send chat messages.
- Randomly connect/disconnect to server configured with `dbg_stress_server` (`localhost` by default).
Previously it also did the following, which is not useful for this debugging feature and only complicates the code unnecessarily:
- Cause images and sounds not to be loaded.
- Render only every tenth frame.
- Always use inactive graphics refresh rate.
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.
Simplify the handling of free texture indices by using `-1` only for indices which are currently in use, whereas the size of the vector is now used to indicate the last free index. Otherwise the assertions incorrectly detect the last texture index always being in use because `-1` was used for both states.
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.
When using `auth_remove`, the key indices for the default helper, mod and admin passwords were not properly adjusted, causing the wrong passwords to be used for the username-less logins.
The key indices for connected clients were also not properly adjusted, causing the wrong identity to be shown for currently authenticated clients when using the `status` command.
Closes#6427.
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.
Replace existing hard-coded support for two "networks" with support for a dynamic list of "communities" which are indexed by a string-ID, though right now the DDNet and KoG communities are still hard-coded. The communities now also support an arbitrary number of associated countries, types and servers. This is a refactoring to prepare for getting the list of communities dynamically from the server and removing the DDNet and KoG tabs from the serverbrowser.
New UI elements were being created for every server info after refreshing the server list. At the same time, old UI elements were not being deleted when the server info objects are deleted. The use of `mutable` for this purpose was also rather unclean.
Now, a separate `std::vector` of UI elements is kept for all server browser entries, instead of associating the UI elements directly with the server info.
