* Optimize string (mis)handling (#8128)Jozef Behran2019-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Optimize statbar drawing The texture name of the statbar is a string passed by value. That slows down the client and creates litter in the heap as the content of the string is allocated there. Convert the offending parameter to a const reference to avoid the performance hit. * Optimize texture cache There is an unnecessary temporary created when the texture path is being generated. This slows down the cache each time a new texture is encountered and it needs to be loaded into the cache. Additionally, the heap litter created by this unnecessary temporary is particularly troublesome here as the following code then piles another string (the resulting full path of the texture) on top of it, followed by the texture itself, which both are quite long term objects as they are subsequently inserted into the cache where they can remain for quite a while (especially if the texture turns out to be a common one like dirt, grass or stone). Use std::string.append to get rid of the temporary which solves both issues (speed and heap fragmentation). * Optimize animations in client Each time an animated node is updated, an unnecessary copy of the texture name is created, littering the heap with lots of fragments. This can be specifically troublesome when looking at oceans or large lava lakes as both of these nodes are usually animated (the lava animation is pretty visible). Convert the parameter of GenericCAO::updateTextures to a const reference to get rid of the unnecessary copy. There is a comment stating "std::string copy is mandatory as mod can be a class member and there is a swap on those class members ... do NOT pass by reference", reinforcing the belief that the unnecessary copy is in fact necessary. However one of the first things the code of the method does is to assign the parameter to its class member, creating another copy. By rearranging the code a little bit this "another copy" can then be used by the subsequent code, getting rid of the need to pass the parameter by value and thus saving that copying effort. * Optimize chat console history handling The GUIChatConsole::replaceAndAddToHistory was getting the line to work on by value which turns out to be unnecessary. Get rid of that unnecessary copy by converting the parameter to a const reference. * Optimize gui texture setting The code used to set the texture for GUI components was getting the name of the texture by value, creating unnecessary performance bottleneck for mods/games with heavily textured GUIs. Get rid of the bottleneck by passing the texture name as a const reference. * Optimize sound playing code in GUIEngine The GUIEngine's code receives the specification of the sound to be played by value, which turns out to be most likely a mistake as the underlying sound manager interface receives the same thing by reference. Convert the offending parameter to a const reference to get rid of the rather bulky copying effort and the associated performance hit. * Silence CLANG TIDY warnings for unit tests Change "std::string" to "const std::string &" to avoid an unnecessary local value copy, silencing the CLANG TIDY process. * Optimize formspec handling The "formspec prepend" parameter was passed to the formspec handling code by value, creating unnecessary copy of std::string and slowing down the game if mods add things like textured backgrounds for the player inventory and/or other forms. Get rid of that performance bottleneck by converting the parameter to a const reference. * Optimize hotbar image handling The code that sets the background images for the hotbar is getting the name of the image by value, creating an unnecessary std::string copying effort. Fix that by converting the relevant parameters to const references. * Optimize inventory deserialization The inventory manager deserialization code gets the serialized version of the inventory by value, slowing the server and the client down when there are inventory updates. This can get particularly troublesome with pipeworks which adds nodes that can mess around with inventories automatically or with mods that have mobs with inventories that actively use them. * Optimize texture scaling cache There is an io::path parameter passed by value in the procedure used to add images converted from textures, leading to slowdown when the image is not yet created and the conversion is thus needed. The performance hit is quite significant as io::path is similar to std::string so convert the parameter to a const reference to get rid of it. * Optimize translation file loader Use "std::string::append" when calculating the final index for the translation table to avoid unnecessary temporary strings. This speeds the translation file loader up significantly as std::string uses heap allocation which tends to be rather slow. Additionally, the heap is no longer being littered by these unnecessary string temporaries, increasing performance of code that gets executed after the translation file loader finishes. * Optimize server map saving When the directory structure for the world data is created during server map saving, an unnecessary value passing of the directory name slows things down. Remove that overhead by converting the offending parameter to a const reference.

* Add on_flood() callback.Auke Kok2017-04-22
| | | | | | | | | | | | | | | | | | | | | This callback is called if a liquid definitely floods a non-air node on the map. The callback arguments are (pos, oldnode, newnode) and can return a `bool` value indicating whether flooding the node should be cancelled (`return true` will prevent the node from flooding). Documentation is added, the callback function was tested with a modified minetest_game. Note that `return true` will likely cause the node's `on_flood()` callback to be called every second until the node gets removed, so care must be taken to prevent many callbacks from using this return value. The current default liquid update interval is 1.0 seconds, which isn't unmanageable. The larger aim of this patch is to remove the lava cooling ABM, which is a significant cost to idle servers that have lava on their map. This callback will be much more efficient.
* Light update for map blocksDániel Juhász2017-04-20
| | | | | | | | | This is not really different from the light update of a voxel manipulator. This update does not assume that the lighting was correct before, therefore it is useful for correction. Also expose this function to the Lua API for light correction, and allow voxel manipulators not to update the light.

* Map generation limit: Make per-worldparamat2017-03-27
| | | | | | | | | | | The setting limits map generation but affects nothing else. Add 'mapgen_limit' to global mapgen parameters. Move 'blockpos_over_mapgen_limit()' to the only place it is called from: map.cpp. Allow teleportation to any part of the world even if over the set mapgen limit. Simplify the reading of this limit in mgvalleys. Remove the 'map_generation_limit' setting.

* Light calculation: New bulk node lighting codeDániel Juhász2017-03-11
| | | | | | | | | | | This commit introduces a new bulk node lighting algorithm to minimize lighting bugs during l-system tree generation, schematic placement and non-mapgen-object lua voxelmanip light calculation. If the block above the changed area is not loaded, it gets loaded to avoid lighting bugs. Light is updated as soon as write_to_map is called on a voxel manipulator, therefore update_map does nothing.
* Improve getPointedThing() (#4346)Dániel Juhász2017-01-04
| | | | | | | | | | | | | | | | | | | * Improved getPointedThing() The new algorithm checks every node exactly once. Now the point and normal vector of the collision is also returned in the PointedThing (currently they are not used outside of the function). Now the CNodeDefManager keeps the union of all possible nodeboxes, so the raycast won't miss any nodes. Also if there are only small nodeboxes, getPointedThing() is exceptionally fast. Also adds unit test for VoxelLineIterator. * Cleanup, code move This commit moves getPointedThing() and Client::getSelectedActiveObject() to ClientEnvironment. The map nodes now can decide which neighbors they are connecting to (MapNode::getNeighbors()).
* Improved lightingDániel Juhász2016-10-27
| | | | | | | | | | | | | | This commit rewrites the procedure that is responsible for light updating. this commit -provides iterative solutions for unlighting and light spreading -introduces a new priority queue-like container for the iteration -creates per-node MapBlock caching to reduce retrieving MapBlocks from the map -calculates with map block positions and in-block relative node coordinates -skips light updating if it is not necessary since the node's new light will be the same as its old light was

* Add MapSettingsManager and new mapgen setting script API functionskwolekr2016-07-03
| | | | | | | | | | | | | | | This commit refactors the majority of the Mapgen settings system. - MapgenParams is now owned by MapSettingsManager, itself a part of ServerMap, instead of the EmergeManager. - New Script API functions added: core.get_mapgen_setting core.get_mapgen_setting_noiseparams, core.set_mapgen_setting, and core.set_mapgen_setting_noiseparams. - minetest.get/set_mapgen_params are deprecated by the above new functions. - It is now possible to view and modify any arbitrary mapgen setting from a mod, rather than the base MapgenParams structure. - MapgenSpecificParams has been removed.

* Add DISABLE_CLASS_COPY macro (and use it)kwolekr2015-10-27
| | | | | | | | | Use this macro to disallow copying of an object using the assignment operator or copy constructor. This catches otherwise silent-but-deadly mistakes such as "ServerMap map = env->getMap();" at compile time. If so desired, it is still possible to copy a class, but it now requires an explicit call to memcpy or std::copy.
