Implement UserCmd command backlog limiting (the new convar 'sv_maxUserCmdProcessTicks' dictates how many ticks can be processed per second). Defaulted to 10, which is (default tick interval (0.05) * default cvar val (10) = 0.5ms window), which is equal to the default of cvar 'sv_maxunlag'.
Before this patch, you could stuff several seconds worth of usercmd's in one second and achieve speed hacking.
RCON lacked encryption, added AES-CTR encryption on RCON frames. Slightly adjusted protocol to take this into account (sending nonces, encrypted data itself, etc).
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.
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.
Properly implement the ConCommandBase and ConCommand classes so we could statically construct all ConCommand objects in the global scope of each translation unit, this way we don't need to put them in a global file and deal with preprocessor directives to compile then in/out for certain projects.
Add missing types to fully mapped out PakGlobals_s struct, which is a 13MiB+ structure! This covers the vast majority of the pakfile system which is why we had to change a bunch of stuff for this patch. This patch also comes with:
- Reversed 'JobFifoLock_s' structure
- Reversed 'PakTracker_s' structure
- Reversed 'PakAssetTracker_s' structure
Many globals have been dropped as they were covered by the large PakGlobals_s singleton.
The pak decoder logic has been changed up as well, we now use a decode mode enumerant which will make it easier to add in more decoders for the pak files in the future.
* Move member vars to correct place, to match it with the engine.
* Added out-of-band network message ID's for the R5 engine.
Also implemented 'ServerDataBlockSender::SendDataBlock()' and 'ClientDataBlockReceiver::AcknowledgeTransmission()'. NOTE that these are currently not tested, and also not in use! The code uses the version stored in the vftable which is what the engine itself provides. These have been implemented for reference only. If they need to be used, they need to be thoroughly tested first!
Rebuild CClientState::ProcessCreateStringTable() and add notes for multiple 'potential' exploit vectors that are currently in place. Also add wrappers for compressing/decompressing net packets.
This patch partially rebuilds the data block sender/receiver. The receiver leaks memory if the sender sends a bogus LZ4 packet, it would allocate memory to copy the encoded data into, from which it would decode it to the scratch buffer, but it would never deallocate this temporary buffer is the LZ4 decoder failed. This has been fixed. The second reason to rebuild these was to look into potential compression optimization. The data block rebuild now also features the latest LZ4 codec.
Mixed MAX_BACKUP_COMMANDS with MAX_NEW_COMMANDS, added proper (confirmed) defines. Also fixed MAX_BACKUP_COMMANDS_PROCESS, which was 60 but was supposed to be 64, so we were 4 backup commands short in CPlayer::ProcessUsercmds().
Only update statistics, this code was mainly added for testing, but testing revealed no additional performance or smoothness improvements, even during >6 hour sessions. The clock drift already gets corrected each frame from Host_RunFrame(). Only update statistics to update CPU and frame times on the client's debug panels if enabled.
The printf specifier does not allow limiting buffer reads. Made the FourCCToString more performant by using a fixed size stack array and creating the fourcc into that which we now use to properly print out the asset magic.
The pak_decompress callback has been fully moved to a dedicated buffered pak decoder function, also added descriptive error to the buffered pak encode function. Fixed a bug in the streamed pak decoder where the next required streamed buffer size would always be below actually required on any subsequent patch rpaks that are getting loaded. Also fixed assert in Pak_ZStreamDecode, as the inbuf position can equal total streamed size, but shall never exceed it!
* Pak_InitDecoder() now takes the output buf and mask as parameters.
* Pak_InitDecoder() checks if provided masks are a power of 2 (required).
* Pak_ComputeRingBufferFrame() now uses the bit mask instead of modulo to determine # bytes used.
* Fixed a bug where PakDecoder_t::bufferSizeNeeded could be bigger than the file stream, causing a deadlock.
The new decoder can now decode patched and custom rpaks files, all issues so far have been fixed. The code still needs some testing and bench marking to make sure
* Use CThreadFastMutex instead
* Rename ISurface to IDebugSurface to prevent a potential name collision with VGUI's ISurface iface if we ever add it
* Fix race condition when setting CPylon::m_HostIP from materialsystem thread, this has been dispatched to the main thread
* Marked 'pylon_matchmaking_hostname' FCVAR_MATERIAL_SYSTEM_THREAD as we use it in the server browser panel.
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.
* split rtech_game and rtech_utils cpp files into multiple files
* rebuilt several large pak load routines for debugging and custom implementations
* moved rson code to rtech_game
* reworked and improved engine and sdk pak precache system
* reversed more of the jobthreads system
Make the utility methods statics within the implementation so it could be used by other structs/classes of the VPK builder as well, these utility functions weren't useful outside the class. This also allowed for the removal of the singleton which had no purpose whatsoever.
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.
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.
Blocking it all together will cause problem when user wants to reset their controller binds. Now we limit execution to 4 per second (default) which doesn't cause problems when resetting any configuration, while also preventing cfg hacks.
This should in theory fix the server and client desync that takes place after multiple hours of uptime without disconnecting or reloading. Note that in this version of the engine the server tick is only send on connect (Titanfall 2 does seem to send it every tick, as this netmsg is also responsible for updating the server percentage on the 'cl_showfps' HUD, which does work as designed). The patched code still writes a 'statistics only' server tick update every tick, but only sends full if the interval time has been reached for that particular client instance.
Enabled by default, and removed playerprofile flag as we want to be able to disable this in the future may it cause problems. All tests done so far (on different hardware) yielded more latency reduction/performance improvements. Also added updated note for convar promo_version_accepted.
These flags only exist in the respawn version of the engine. Renamed 'CNetChan::unknown_challenge_var' to 'CNetChan::m_nRealTimePackets'. This field counts the number of packets sent while the frame time wasn't prescaled with the 'host_timescale' cvar, see r5apex.exe+0x3093C0 (140309FC0).
