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.
* 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).
Original credits goes to @Rogier-5
* Merge common attributes between LuaEntitySAO & PlayerSAO to UnitSAO
* Make some functions const
* Improve some lists performance by returning const ref
Signed-off-by: Loic Blot <loic.blot@unix-experience.fr>
* Environment code refactoring
* Cleanup includes & class declarations in client & server environment to improve build speed
* ServerEnvironment::m_gamedef is now a pointer to Server instead of IGameDef, permitting to cleanup many casts.
* Cleanup IGameDef
* Move ITextureSource* IGameDef::getTextureSource() to Client only.
* Also move ITextureSource *IGameDef::tsrc() helper
* drop getShaderSource, getSceneManager, getSoundManager & getCamera abstract call
* drop unused emerge() call
* cleanup server unused functions (mentionned before)
* Drop one unused parameter from ContentFeatures::updateTextures
* move checkLocalPrivilege to Client
* Remove some unnecessary casts
* create_formspec_menu: remove IWritableTextureSource pointer, as client already knows it
* Fix some comments
* Change required IGameDef to Server/Client pointers
* Previous change that game.cpp sometimes calls functions with Client + InventoryManager + IGameDef in same functions but it's the same objects
* Remove duplicate Client pointer in GUIFormSpecMenu::GUIFormSpecMenu
* drop ClientMap::sectorWasDrawn which is unused
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
Schematics can already be placed with a param2 value, but not
simple 1-node plant decorations of the simple type.
This adds a `param2` field to the simple deco type that is
checked to be between 0 and 255, and put to the placed node
at mapgen.
This can be used to put a degrotate value in, or e.g. a fill
value for leveltype nodes, or a place_param2 value at mapgen
placement, or vary the shape of meshoptions plantlike drawtype.
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.
Active objects that are attached to other objects are not safe
from deletion. As a result, the parent object may have a reference
to an id of a child's that no longer exists.
If at some point an attempt is made to manipulate the child,
enviromment->getActiveObject(child-id) returns NULL. Using the
NULL pointer causes the crash...
* 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
Modification of the emergeblocks internal state was not protected
by a lock, causing a race condition.
This can be reproduced by repeatedly running emergeblocks for an
already-generated section of the map (with multiple emerge threads).
* remove IGameDef from Player class, only LocalPlayer has it now
* move many attributes/functions only used by LocalPlayer from Player to LocalPlayer
* move many attributes/functions only used by RemotePlayer from Player to RemotePlayer
* make some functions const
* hudGetHotbarSelectedImage now returns const ref
* RemotePlayer getHotbarSelectedImage now returns const ref
* various code style fixes
* ClientEnvironment now uses UNORDERED MAP for active objects
* Use RemotePlayer and LocalPlayer everywhere it's possible
* Minor code style fixes
* Drop Client::getBreath() unused function
* Server/Client Environments now have an helper to cast Player object in the right type to use it
* Server: use RemotePlayer everywhere and remove previous added casts
* Client: use LocalPlayer where needed
* Environment: remove unused functions (getPlayers(), getRandomConnectedPlayer(), getNearestConnectedPlayer())
* LocalPlayer take ownership of maxHudId as it's the only caller
* RemotePlayer take ownership of day night ratio as it's the only user
* Pass getPlayerControl as const reference to prevent object copy on each call (perf improvement in ObjectRef::l_get_player_control call)
* getPlayerSAO is now only RemotePlayer call
* get/setHotbarItemCount is now RemotePlayer owned
* Server: Use RemotePlayer instead of Player object on concerned call to properly fix the object type
* PlayerSAO now uses RemotePlayer instead of Player because it's only server side
* ObjectRef::getplayer also returns RemotePlayer as it's linked with PlayerSAO
This is part 2 for 5f084cd98d7b3326b51320455364337539710efd
Other improvements:
* Use the defined ItemGroupList when used
* make Client::checkPrivilege const
* inline some trivial functions
* Add ActiveObjectMap typedef
* Add SettingsEntries typedef
* Move included json code to jsoncpp subdirectory
This is needed to avoid having to specify the minetest src directory
as a system include when fixing the json includes.
* Fix json includes
They used "", so that the compiler searches the project's directory
first. The result was that when compiling with a system jsoncpp,
the project's own version of json.h was still included, instead of
the system version.
The includes now use <>, so a system location, or one specified with
'-Ilocation' is searched only.
* Fix for jsoncpp deprecated function warning
When compiling with a newer version of jsoncpp (and
ENABLE_SYSTEM_JSONCPP=true), jsoncpp emits a warning
about a deprecated function that minetest uses.
This fallback to std::map & std::set for older compilers
Use UNORDERED_SET as an example in decoration and ore biome sets
Use UNORDERED_MAP as an example in nameidmapping
l_request_insecure_environment didn't ignore all whitespace in the
secure.trusted_mods config option.
Replaces std::remove with std::remove_if and the isspace function.
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.
- Move mapgen creation logic out of EmergeManager and into Mapgen
- Internally represent mapgen type as an enum value, instead of a string
- Remove the need for a MapgenFactory per mapgen

Gives a convenient way to check a player's password.
This entirely bypasses the SRP protocol, so should be used
with great care.
This function is not intended to be used
in-game, but solely by external protocols, where no
authentication of the minetest engine is provided, and
also only for protocols, in which the user already gives the
server the plaintext password.
Examples for good use are the classical http form, or irc,
an example for a bad use is a password change dialog inside
formspec.
Users should be aware that they lose the advantages of the SRP
protocol if they enter their passwords for servers outside the
normal entry box, like in in-game formspec menus,
or through irc /msg s,
This patch also fixes an auth.h mistake which has mixed up the
order of params inside the decode_srp_verifier_and_salt function.

Adds the particle option `collision_removal = bool`
Some particles are hard to use right now since they either go through
solid blocks (without collision detection), and with collision
detection enabled they (e.g. raindrops) would just stop dead on the
floor and sit there until they expire, or worse, scrape along a wall
or ceiling.
We can solve the problem by adding a boolean flag that tells the
particle to be removed if it ever collides with something. This will
make it easier to add rain that doesn't fall through your roof or stick
on the top of it. Or clouds and smoke that don't go through trees.
Particles that collide with this flag are marked expired
unconditionally, causing them to be treated like normal expired
particles and cleaned up normally.
Documentation is adjusted accordingly.
An added bonus of this patch is that particles can potentially collide
many times with nodes, and this reduces the amount of collisions to 1
(max), which may end up reducing particle load on the client.
BiomeGen defines an interface that, given a set of BiomeParams, computes biomes
for a given area using the algorithm implemented by that specific BiomeGen.
This abstracts away the old system where each mapgen supplied the noises
required for biome generation.
* Fix naming style for methods and classes:
Use camelCase for methods and PascalCase for classes as
code style demands it. And use sneak_case for methods that
are not member of a class.
* Replace "* " with " *" for Pointers
* Same for references
* Put function body opening braces on new line
* Other misc minor non functional style improvements
The legacy init packet (pre v25) sends information about the client's
password that a server could use to log in to other servers if the
username and password are the same. All the other benefits of SRP of
protocol v25 are missed if the legacy init packet is still sent during
connection creation.
This patch adds an option to not send the v25 init packet. Not sending
the v25 packet means breaking compat with pre v25 servers, but as the
option is not enabled by default, no servers are affected unless the
user explicitly flips the switch. More than 90% of the servers on the
serverlist support post v25 protocols.
The patch also fixes a bug with greying out of non compliant servers
being done wrongly, the min and max params were mixed.
* No function overloading
* Adhere coding style and with method names following
lowercase_underscore_style
* Use std::string in external API, handling these is
much more fun
I've written several experimental bits of code that revolve around the
need for a consistent calendar, but implementing one is extremely hard
in mods due to time changes and mods overriding core.get_timeofday(),
which will conflict.
The second part of the problem is that doing this from a mod requires
constant maintenance of a settings file.
An implementation in core is trivial, however, and solves all of
these problems at virtually no cost: No extra branches in server
steps, and a single branch when minetest.set_time_of_day(), which is
entirely reasonable.
We store the day_count value in env_meta.txt.
The use case is obvious: This change allows mods to create an actual
virtual calendar, or properly account for seasonal changes, etc..
We add a "/days" chatcommand that displays the current day count. No
permissions are needed. It can only retrieve the day count, not
modify it.
This allows mods to perform both asynchronous and synchronous HTTP
requests. Mods are only granted access to HTTP APIs if either mod
security is disabled or if they are whitelisted in any of the
the secure.http_mods and secure.trusted_mods settings.
Adds httpfetch_caller_alloc_secure to generate random, non-predictable
caller IDs so that lua mods cannot spy on each others HTTP queries.
Previously you could steal a secure environment from a trusted mod by wrapping
request_insecure_environment with some code like this:
local rie_cp = minetest.request_insecure_environment
local stolen_ie
function minetest.request_insecure_environment()
local ie = rie_cp()
stolen_ie = stolen_ie or ie
return ie
end
`errorstream` must not be overly verbose as clientside it is directly printed
onto the ingame chat window. These days, the serverlist can contain > 200k bytes,
so better print it to warningstream if the data buffer is too long.
Fix the type of the threshold value for mapgen.
The commit
a78dd7f2b6b0e1fefdbaa1ae21b722dd4459e4f4 "Fix spelling of noise_threshold"
has changed it to be read as int, but it can have non-integral values too.
Thanks to @kwolekr for pointing this out.

Also add to LuaVoxelManip calc_lighting for use in mapgen mods
Remove the 2 argument calcLighting, mapgens now use the 5
argument form to specify the volumes for propagateSunlight and
spreadLight
In mgsinglenode replace calcLighting with setLighting and
clean-up use of tabs and spaces
This adds a chat console the server owner can use for administration
or to talk with players.
It runs in its own thread, which makes the user interface immune to
the server's lag, behaving just like a client, except timeout.
As it uses the same console code as the f10 console, things like nick
completion or a scroll buffer basically come for free.
The terminal itself is written in a general way so that adding a
client version later on is just about implementing an interface.
Fatal errors are printed after the console exists and the ncurses
terminal buffer gets cleaned up with endwin(), so that the error still
remains visible.
The server owner can chose their username their entered text will
have in chat and where players can send PMs to.
Once the username is secured with a password to prevent anybody to
take over the server, the owner can execute admin tasks over the
console.
This change includes a contribution by @kahrl who has improved ncurses
library detection.
