Craig Robbins ced6d20295 For usages of assert() that are meant to persist in Release builds (when NDEBUG is defined), replace those usages with persistent alternatives 2015-03-07 22:41:47 +10:00
Craig Robbins fdb9140825 Change find_surface_nodes_in_area to find_nodes_in_area_under_air 2015-02-27 21:42:00 +10:00
Loic Blot 0f556d0c7f Add find_surface_nodes_in_area LUA call which permit to only get the nodes which touch air. This permit to massively improve performance for mods like plantlife 2015-02-27 21:34:33 +10:00
Loic Blot f8d5af7536 SAO work: ActiveObject types & SAO cleanup * Replace u8 types with ActiveObjectType. * Merge content_object.h into activeobject.h * Remove DummyLoadSAO, it's now unused. * Remove ItemSAO, it's also unused 2015-02-17 09:09:50 +01:00
Loic Blot 7c8793cbea Performance Improvement: Use a cache which caches result for getFacePositions.
This greatly reduce the number of std::list generated by caching the result, which is always constant for each radius selected.
In the callgrind map, you will see original:
  * 3.3M calls to std::list for 9700 calls to getFacePositions
In the modified version, you will see:
  * 3.3K calls to std::list for 6900 call to getFacePositions
Callgrind map is here: #2321

it's a huge performance improvement to l_find_node_near

Craig Robbins f33d31693e Fix seg fault if popping from empty stack (L-system trees)
See: https://github.com/minetest/minetest/issues/1525

Background
Wuzzy2: If you attempt to spawn a L-system tree with minetest.spawn_tree, you can make Minetest crash if it is attempted to pop an empty stack.

ShadowNinja: This shouldn't cause a segmentation fault, but it should throw a Lua error

Commit Description
This commit throws a Lua error instead of causing a segmentation fault. The server will still "crash" but will include a Lua backtrace.

L-Systems fix randomness
Unless a random seed is provided (via Lua treedef) seed the PRNG with a different seed for each tree
Resolves: https://github.com/minetest/minetest/issues/1469

Fix l-system crash when treedef random_level not set by Lua

sapier c24e0753fc Mod profiling support
Config settings:
profiling = true/false (gather statistics)

sapier ab43377577 Move scriptapi to separate folder (by sapier)
On the lua side, notably minetest.env:<function>(<args>) should now
be replaced by minetest.<function>(<args>).
The old way is and will stay supported for a long time.

Also:
Update and clean up lua_api.txt (by celeron55)
Move EnvRef to lua and remove add_rat and add_firefly (by kahrl)
Add separate src/util/CMakeLists.txt, other minor fixes (by kahrl)
