This patch splits host logic from CServerListManager. CServerListManager is actually meant for the client to manage the server list to which the client could connect to. The hosting logic has been moved to the new CServerHostManager class.
Previously, we stored all the hosting details in CServerListManager, with connection criteria in CPylon, this data has been moved over to CServerHostManager as well.
Previously, we also needed a mutex to access the server host data, function HostState_KeepAlive() has been refactored to the point this mutex is no longer necessary as the only threaded process is the actual request, the rest is being applied in the main thread. We also now only construct a NetGameServer_t struct if we actually plan to host.
Access to CPylon::m_Language is now also protected by a mutex, as the change callback of cvar 'language' and the threaded method 'CPylon::QueryServer()' are competing for access.
Avoid heap memory allocation and a level of indirection. This allows the compiler to optimize the program even more. No logic has been changed in this patch.
Remove workaround that was implemented to counter a crash during the beginning of this project, this issue was long solved but the workaround was never removed. Clearing the last precached VPK name prevents the engine from helping other threads to properly unload existing handles, if at all.
The KeyValues class belongs here. Also reimplemented most loading methods for KeyValues, and adjusted the VPK building code to account for it. Pointers to the engine's implementation of KeyValues have been moved to a separate header ('keyvalues_iface.h'), as this allows external tools code to utilize the standalone KeyValues class implementation. Playlist utilities are completely separated from the KeyValues header; these have nothing to do with KeyValues other than manipulating a global KeyValues object for the playlists, and thus have been named as such and moved to rtech/playlists.
They were all strings; changed them to what made most sense for each field type. Changes:
"hidden": string -> bool
"port": string -> int
"checksum": string -> uint
"playerCount": string -> int
"maxPlayers": string -> int
* 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!
* 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).
* Only run '_DownloadPlaylists_f()' in the main thread, schedule for next frame if we aren't in the main thread. (this should fix crash cases related to disconnecting from the game).
* Locked read/write to CBrowser members (thread for obtaining the server list is detached, but once the 'slow' post operation in this thread is complete, mutex lock is acquired (locking the render thread if the browser is active) to set the string members of CBrowser, this operation is very fast as we only set the string and the color after the http post operation (this never caused a crash, but the behavior without any lock mechanism is technically undefined regardless).
* Obtain the host name dynamically from the ConVar 'pylon_matchmaking_hostname' (atomic operation). Initial approach was deleting the whole master server pointer just to construct a new httpclient object..
Run all Cbuf_Execute calls in the main thread. This should fix every problem related to (but not only):
* Connecting to server while RUI dialogue is still open.
* Connecting to server while in an active game.
* Running 'weapon_reparse'.
