* PostgreSQL & SQLite3 doesn't setModified(false) on RemotePlayer, then player is saved on each server save call. This results in heavy useless writes.
* PostgreSQL & SQLite3 ack engine meta write whereas db commit hasn't been performed. If commit failed write has failed. We mustn't notify engine write is done.
* serializing player meta must not setModified(false) because it didn't ensure write has been done
* add RemotePlayer::on_successfull_save callback to do the flag update on a successful save
* Adds Lua methods 'set_rotation()' and 'get_rotation'. Also changed some method names to be more clear. Instead of an f32 being sent over network for yaw, now a v3f is sent for rotation on xyz axes. Perserved Lua method set_yaw/setyaw so that old mods still work, other wise to set yaw they would need to switch to set_rotation(0, yaw, 0).
* Update JsonCPP to 1.8.3
* Fix deprecated functions
Json::FastWriter, Json::StyledWriter and Json::Reader are marked deprecated since 1.1 and are deprecated in 0.8 but not shown at compilation time.
Use new methods to serialize/deserialize
* Respect object property hp_max field for players
This allows modders to configure the maximal HP per player
* Statbars: Downscale bar to full 20 HP when exceeding this value
Add default max HP for players and breath constants to builtin
Document the constants
* Rename PLAYER_MAX_HP -> PLAYER_MAX_HP_DEFAULT
* Player data to Database
Add player data into databases (SQLite3 & PG only)
PostgreSQL & SQLite: better POO Design for databases
Add --migrate-players argument to server + deprecation warning
* Remove players directory if empty
* Some performance optimizations
This is globally removing some memory useless copy
* use a const ref return on std::string Settings::get to prevent data copy on getters which doesn't need to copy it
* pass some stack created strings to static const as they are not modified anywhere
* Camera: return nametags per const ref instead of a list pointer, we only need to read it
* INodeDefManager: getAll should be a result ref writer instead of a return copy
* INodeDefManager: getAlias should return a const std::string ref
* Minimap: unroll a Scolor creation in blitMinimapPixersToImageRadar to prvent many variable construct/destruct which are unneeded (we rewrite the content in the loop)
* CNodeDefManager::updateAliases: prevent a idef getall copy
* Profiler: constness
* rollback_interface: create real_name later, and use const ref
* MapBlockMesh updateFastFaceRow: unroll TileSpec next_tile, which has a cost of 1.8% CPU due to variable allocation/destruction,
* MapBlockMesh updateFastFaceRow: copy next_tile to tile only if it's a different tilespec
* MapBlockMesh updateFastFaceRow: use memcpy to copy next_lights to lights to do it in a single cpu operation
* mod can create a ModMetadata object where store its values and retrieve it.
* Modmetadata object can only be fetched at mod loading
* Save when modified using same time as map interval or at server stop
* add helper function to get mod storage path
* ModMetadata has exactly same calls than all every other Metadata
* This backend permit mods to store extra players attributes to a common interface.
* Add the obj:set_attribute(attr, value) Lua call
* Add the obj:get_attribute(attr) Lua call
Examples:
* player:set_attribute("home:home", "10,25,-78")
* player:get_attribute("default:mana")
Attributes are saved as a json in the player file in extended_attributes
key
They are saved only if a modification on the attributes occurs and loaded
when emergePlayer is called (they are attached to PlayerSAO).
Breath is now handled server side. Changing this behaviour required some modifications to core:
* Ignore TOSERVER_BREATH package, marking it as obsolete
* Clients doesn't send the breath to server anymore
* Use PlayerSAO pointer instead of peer_id in Server::SendPlayerBreath to prevent a useless lookup (little perf gain)
* drop a useless static_cast in emergePlayer
PlayerSAO::disconnected() function was historical and remove the link between SAO and RemotePlayer session. With previous attributes linked to RemotePlayer saving was working. But now attributes are read from SAO not RemotePlayer and the current serialize function verify SAO exists to save the player attributes.
Because PlayerSAO::disconnected marks playersao for removal, only mark playerSAO for removal and let PlayerSAO::removingFromEnvironment do the correct saving behaviour and all the disconnection process instead of doing a partial removal and let the server loop doing the RemotePlayer cleanup and remove some saved attributes...
* Create UnitSAO, a common part between PlayerSAO & LuaEntitySAO
* Move breath to PlayerSAO & LocalPlayer
* Migrate m_yaw from (Remote)Player & LuaEntitySAO to UnitSAO
* Migrate m_yaw from Player to LocalPlayer for client
* Move some functions outside of player class to PlayerSAO/RemotePlayer or LocalPlayer depending on which class needs it
* Move pitch to LocalPlayer & PlayerSAO
* Move m_position from Player to LocalPlayer
* Move camera_barely_in_ceiling to LocalPlayer as it's used only there
* use PlayerSAO::m_base_position for Server side positions
* remove a unused variable
* ServerActiveObject::setPos now uses const ref
* use ServerEnv::loadPlayer unconditionnaly as it creates RemotePlayer only if it's not already loaded
* Move hp from Player to LocalPlayer
* Move m_hp from LuaEntitySAO to UnitSAO
* Use m_hp from PlayerSAO/UnitSAO instead of RemotePlayer
