This combats the problem of sending the hundreds of
"creative" / "armor" or whatever detached invs that
exist on popular servers to each and every player
on join or on change of said invs.
If a tool wears out and is destroyed, it's itemstack count
goes to 0, and we can optionally play a breaking sound.
This patch implements playing a breaking sound when this
occurs. Sounds need to be added to the tool itemdef
registration as the sound name string in the .sound.breaks
member.
Fixes#4778 which was about the error:
ServerError: Lua: Runtime error from mod '' in callback item_OnPlace():
/usr/local/share/minetest/builtin/game/item.lua:278: attempt to call global 'check_attached_node' (a nil value)
The issue was a regression of commit 649448a2a91fbf3e944b2f2e739f4e2292af1df0
"Rename nodeupdate and nodeupdate_single and make them part of the official API"
Now, the renamed forms of nodeupdate and nodeupdate_single are part of the official API.
As nodeupdate has been used by Minetest Game and in mods despite of not
being part of the official API, we ease the transition by still supporting
it for the 0.4.15 release. After the release, the two functions can be removed.
The removal will not violate the stability promise, as that promise only
includes the official and documented API.
Also, make some formerly global functions local. They most likely haven't
been used by mods, therefore they won't get stubs with deprecation warnings,
hard erroring directly.
Original commit by t4im, rebased and developed by paramat.
Fix CONTENT_IGNORE being replaced by falling nodes or causing large
areas of sand to collapse into itself.
Format some conditional code for clarity.
Add and clarify some comments.
The fallback vector is in case 'wallmounted to dir' is nil due
to voxelmanip placing a wallmounted node without resetting a
pre-existing param2 value that is out-of-range for wallmounted.
The fallback vector corresponds to param2 = 0.
Add 'core.LIGHT_MAX = 14' to builtin/game/constants.lua with the intention
to replace misplaced 'default.LIGHT_MAX = 14' in Minetest Game.
Add comment in light.h requiring the constant be changed in both places.
Add lighting bug warning to note in lua_api.txt.
There are hundreds of mod uses of 15 which causes a lighting bug.
core.check_player_privs accepts as first argument a name or player object, but just tested for a string.
This caused crashes inside builtin, when being passed any unexpected types.
This provides a better (duck-typing like) test, better error reporting.
Use the setting "profiler.load" to enable profiling.
Other settings can be found in settingtypes.txt.
* /profiler print [filter] - report statistics to in-game console
* /profiler dump [filter] - report statistics to STDOUT and debug.txt
* /profiler save [format [filter]] - saves statistics to a file in your worldpath
* txt (default) - same treetable format as used by the dump and print commands
* csv - ready for spreadsheet import
* json - useful for adhoc D3 visualizations
* json_pretty - line wrapped and intended json for humans
* lua - serialized lua table of the profile-data, for adhoc scripts
* /profiler reset - reset all gathered profile data.
This can be helpful to discard of any startup measurements that often spike during loading or to get more useful min-values.
[filter] allows limiting the output of the data via substring/pattern matching against the modname.
Note: Serialized data structures might be subject to change with changed or added measurements.
csv might be the most stable, due to flat structure.
Changes to the previous version include:
* Updated and extended API monitoring
* Correct calculation of average (mean) values (undistorted by idleness)
* Reduce instrumentation overhead.
* Fix crashes related to missing parameters for the future and occasional DIV/0's.
* Prevent issues caused by timetravel (overflow, timejump, NTP corrections)
* Prevent modname clashes with internal names.
* Measure each instrumentation individually and label based on registration order.
* Labeling of ABM's and LBM's for easier classification.
Giving several ABM's or LBM's the same label will treat them as one.
Missing labels will be autogenerated based on name or registration order.
* Configurable instrumentation and reporting. Skip e.g. builtin if you don't need it.
* Profile the profiler to measure instrumentation overhead.
This allows a nodedef to specify a fixed value for param2 to be
used for all normal placements.
There are several uses for this:
- nodes that require param2 to be set to a non-zero value for
internal mod use. E.g. leafdecay could use this to detect that
leaves are played by players.
- force wallmounted or facedir value at placement at placement
This overrides any player look direction or other on-the-fly
param2 setting during placement.
This seems very little cost and matches the old behavior more
closely. This will cause some more falling nodes to get added
to falling clusters. With the efficiency of the algorithm, this
really doesn't do much damage.
This took me a while to figure out. We no longer visit all 9 block
around and with the touched node, but instead visit adjacent plus
self. We then walk -non- recursively through all neigbors and if
they cause a nodeupdate, we just keep walking until it ends. On
the way back we prune the tail.
I've tested this with 8000+ sand nodes. Video result is here:

Took ~ 10 seconds to process and return to normal.

Commit
65c09a96f41705bb8e75fc5ff4276342be91ed11 "Set acceleration only once in falling node"
has made the acceleration being set only once.
But this has introduced a regression.
Fix#3884.
Undoubtably this may cause problems later if unchecked.
