* Avoid crash caused by, and improve, 'findSpawnPos()' (#8728)Paramat2019-08-07
| | | | | | | | | | | | | | | | Avoid an unsuitable spawn position (which if outside mapgen limits can cause a crash) if the main 0-3999 loop reaches its end. Fallback to a spawn at 0,0,0. Check the mapgen-returned 'spawn_level' value for being outside limits. When 'air_count' reaches 2, move back down 1 to spawn in the lower empty node. If the spawn position is disallowed by 'objectpos_over_limit()', 'break' from loop instead of 'continue' because positions above are probably also over limit. Reset 'air_count' to 0 if an obstruction is found, to make 'air_count' consecutive empty nodes. Allow spawn in 'airlike' drawtype nodes such as mod-added vacuum, alien atmospheres, fog etc. Add clarifying comments and improve codestyle.

* 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.
* Force send a mapblock to a player (#8140)sofar2019-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Force send a mapblock to a player. Send a single mapblock to a specific remote player. This is badly needed for mods and games where players are teleported into terrain which may be not generated, loaded, or modified significantly since the last player visit. In all these cases, the player currently ends up in void, air, or inside blocks which not only looks bad, but has the effect that the player might end up falling and then the server needs to correct for the player position again later, which is a hack. The best solution is to send at least the single mapblock that the player will be teleported to. I've tested this with ITB which does this all the time, and I can see it functioning as expected (it even shows a half loaded entry hallway, as the further blocks aren't loaded yet). The parameter is a blockpos (table of x, y, z), not a regular pos. The function may return false if the call failed. This is most likely due to the target position not being generated or emerged yet, or another internal failure, such as the player not being initialized. * Always send mapblock on teleport or respawn. This avoids the need for mods to send a mapblock on teleport or respawn, since any call to `player:set_pos()` will pass this code.

* Fix randomly rejected form field submits (#8091)Jozef Behran2019-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a formspec is submitted from a form fields handling callback of another form (or "formspec shown from another formspec"), the fields submitted for it can get rejected by the form exploit mitigation subsystem with a message like "'zorman2000' submitted formspec ('formspec_error:form2') but server hasn't sent formspec to client, possible exploitation attempt" being sent to logs. This was already reported as #7374 and a change was made that fixed the simple testcase included with that bug report but the bug still kept lurking around and popping out in more complicated scenarios like the advtrains TSS route programming UI. Deep investigation of the problem revealed that this sequence of events is entirely possible and leads to the bug: 1. Server: show form1 2. Client *shows form1* 3. Client: submits form1 4. Server: show form2 5. Client: says form1 closed 6. Client *shows form2* 7. Client: submits form2 What happens inside the code is that when the server in step 4 sends form2, the registry of opened forms is updated to reflect the fact that form2 is now the valid form for the client to submit. Then when in step 5 client says "form1 was closed", the exploit mitigation subsystem code deletes the registry entry for the client without bothering to check whether the form client says was closed just now is indeed the form that is recorded in that entry as the valid form. Then later, in step 7 the client tries to submit its valid form fields, these will be rejected because the entry is missing. It turns out the procedure where the broken code resides already gets the form name so a simple "if" around the offending piece of code fixes the whole thing. And advtrains TSS agrees with that.

* Add Lua methods 'set_rotation()' and 'get_rotation()' (#7395)CoderForTheBetter2018-11-28
| | | | * 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).
