Code actually doesn't need to be ran in the server frame thread. All the code really does is preparation work. Run it in the main thread but do join the server frame thread (FCVAR_SERVER_FRAME_THREAD) as we can't do concurrent work on the server VM.
Previously we did sq_pushroottable() and a subsequent sq_call() after compiling the text buffer, but this didn't work for code that was threaded, or using Get/SetNetVar* functions.
The second issue was that the callback for the "script" command was ran in the main thread. Server script should always run in the server frame thread, the Set/GetNetVar* functions check thread id to retrieve the correct VM context, so running server script from the main thread ended up with Set/GetNetVar* functions retrieving the client VM context rather than server's, causing undefined behavior.
Script commands are now queued to the server frame thread, ultimately fixing this bug.
Also fixed a small bug with function 'sq_compilebuffer()'; it takes an extra argument but this wasn't taken into account in the SDK.
Can be toggled with the new cvar 'host_autoReloadRespectGameState', and used in combination with the new server script func 'SetAutoReloadState( bool state )'. This makes sure that even when the timer reaches 'host_autoReloadRate', it would wait with the reload until the game itself is finished (which is when SetAutoReloadState( true ) is being called from scripts).
Fully implemented ConVar class so we could statically construct all SDK convars, this avoids a level of indirection, and allows for creating ConVar's everywhere in the project.
This patch also removed the settings tab of the ImGui server browser, as it has threading issues, while it technically never caused a crash yet, it has been removed as there was no point keeping it vs the work required to make it thread save (it only managed 2 convars which are perfectly manageable through cfg's or the in-game console).
Also temporarily disabled the creation of ConVar's in the mod system due to a memory leak, we would allocate and register a convar based on details parsed out of a mod file definition, but never unregister and free it.
Originally, we store the search results in a CMemory instance which we then assign to the actual function pointer. CMemory is just a pointer class; we can assign the results directly to the actual function pointer. This commit reduces a lot of code verbosity, and also reduced roughly 2KiB worth of static pointers in the resulting executable. This commit also officially deprecates the support for any GameDLL's below S3 (Season 3), since it makes more sense to port the assets from earlier/later games back to the version this SDK supports.
Utilize the new IDetour::DetourSetup() code, IDetour::Attach and IDetour::Detach have been removed in favor of this (significantly reduces chance of user error). Since the template check happens in the idetour header, it is much more aggressive on type mismatches, such as a difference in parameter types, between the function and detour, will now raise a compile time error. As a result, some type mismatches have been fixed in this commit as well.
CClient array is part of the CPlayer class. The array has been added, filling up most of the 'unknown' gap. Vtable override functions have been added as the array is static, and therefore requires an implementation of the vtable, these are just stubs however, since the vtable pointer points to the implementation in the engine.
Find regex pattern:
inline auto ([a-zA-Z0-9_]+) = ([a-zA-Z0-9_]+)\.RCast<([a-zA-Z0-9_:<>*]+) *\(\*\)\(([^)]*)\)>\(\);
Replace regex pattern:
inline $3(*$1)($4);
This commit also removes the unnecessary initialization (which was required to type the auto variables),
and therefore removed 6kb of unnecessary dynamic initialization code.
* All libraries have been isolated from each other, and build into separate artifacts.
* Project has been restructured to support isolating libraries.
* CCrashHandler now calls a callback on crash (setup from core/dllmain.cpp, this can be setup in any way for any project. This callback is getting called when the apllication crashes. Useful for flushing buffers before closing handles to logging files for example).
* Tier0 'CoreMsgV' function now calls a callback sink, which could be set by the user (currently setup to the SDK's internal logger in core/dllmain.cpp).
TODO:
* Add a batch file to autogenerate all projects.
* Add support for dedicated server.
* Add support for client dll.
Bugs:
* Game crashes on the title screen after the UI script compiler has finished (root cause unknown).
* Curl error messages are getting logged twice for the dedicated server due to the removal of all "DEDICATED" preprocessor directives to support isolating projects. This has to be fixed properly!
SV_IsClientBanned is now checked after the creating of CClient, and thus 'CServer::AuthClient' has been inlined into 'CServer::ConnectClient'. Since we have to request the master server to check whether or not this particular client is globally banned, we have to detach it into a separate thread, and process the results back into the main thread once finished. This takes too much time, so we connect the client anyways and if the master server marked it as 'banned', we disconnect it right away.
* Added new member 'm_nSpawnCount'.
* Added hook for 'CServer::RunFrame'.
* Abstract class 'IServer' no longer exists in this engine, inherit from 'IConnectionlessPacketHandler' instead (see RTTI in engine executable).
This change was planned for a long time. This moves all REGISTER calls to a single translation unit, this is required as we currently added a very dirty workaround for not registering duplicates by checking if VFTable pointer was already present in the vector... Registering from single translation unit prevents duplicate instances that gets created if header is included by more cpp files.
Reworking this reduced 100kb+ of compiled code. This commit also reworked the way functions/variables/constant gets logged with their addresses; the new code formats them on the fly, and allows for resize at any time. Formatting is no longer required by programmer.
TODO: currently there are some compile errors for dedicated and client dll's. These will be resolved very soon as they need to be properly worked out still (server & client only stuff needs to be properly split). Use the 'main' (stable) branch for the time being if you need to compile these dll's.
The Season 3 versions of the executable deadlock when threaded bone setup has been enabled on the client while the listen server has ran at least once during the process lifetime.
* Added validity checks for player names, they must be UTF-8 encoded, else game clients will crash attempting to set non-UTF-8 player names in RUI.
* CServer::RejectConnection now takes a 'v_netadr_t*', previously it was 'user_creds_s*', which worked as 'v_netadr_t' is the first member in 'user_creds_s'.
* Programmer must now manually pass a character buffer to 'v_net_adr::GetAddress(...)'.
* Fixed bug where multiple of the same entries get added to the global ban/refuse list.
* Fixed bug where we still use the client instance after deleting it in 'CBanSystem::BanListCheck()'.
* Load banlist at a later state (not at construction of class), this is needed for a future change of adapting the 'business' code to feature the game's FileSystem.
* CServer cleanup.
* More detailed ban messages (banned, added to refused list, removed from slot, etc..).
* Use localization key for banned message ("#Valve_Reject_Banned").
* Add const qualifiers to all CPylon methods.
Note:
* This commit requires changes on the master server, these changes are already performed, however the new master server isn't live yet until we publish the new release.
* Run 'CHostState::Think()' in the main thread.
* Construct 'NetGameServer_t' objects in main thread before dispatching (TODO: browser).
* Dispatch the call to 'CBanSystem::AddConnectionRefuse' from 'SV_IsClientBanned' to the main thread if we aren't main.
* Return bool for CBanSystem::AddEntry and CBanSystem::DeleteEntry for future optimizations (next commit).
