The only valid usecase for these is interfacing with OS APIs
that want a locale/OS-specific multibyte encoding.
But they weren't used for that anywhere, instead UTF-8 is pretty
much assumed when it comes to that.
Since these are only a potential source of bugs and do not fulfil
their purpose at all, drop them entirely.
A Minetest peer initiates a connection by sending a packet with an invalid peer_id, for whatever reason the code for doing this ran on both the client and the server meaning you could connect to a client if you knew what the address:port tuple it was listening on.
Run unused functions reported by cppcheck
This change removes a few (but not all) unused functions.
Some unused helper functions were not removed due to their complexity and potential of future use.
Features:
* Define Minimap available modes (surface/radar, scale) from Lua, using player:set_minimap_modes()
* New HUD elements for displaying minimap with custom size and placing
* New minimap mode for displaying a texture instead of the map
This commit clarifies the maximal length of the serialized strings.
It will avoid accidental use of serializeString() when a larger string can be expected.
Removes unused Wide String serialization functions
Replace on_auth_fail callback with more versatile on_authplayer
Better clarify account login process in Lua API documentation
Change initial timestamp for newly registered accounts to -1
This adds support for optional “off state” icons for statbars. “off state icons” can be used to denote the lack of something, like missing hearts or bubbles.
Add "off state" textures to the builtin statbars.

* Server::overrideDayNightRatio doesn't require to return bool
There is no sense to sending null player, the caller should send a valid object
* Server::init: make private & cleanup
This function is always called before start() and loads some variables which can be loaded in constructor directly.
Make it private and call it directly in start
* Split Server inventory responsibility to a dedicated object
This splits permit to found various historical issues:
* duplicate lookups on player connection
* sending inventory to non related player when a player connects
* non friendly lookups on detached inventories ownership
This reduce the detached inventory complexity and also increased the
lookup performance in a quite interesting way for servers with thousands
of inventories.
New formspec elements:
- `scroll_container[<X>,<Y>;<W>,<H>;<scrollbar name>;<orientation>;<scroll factor>]`
- `scroll_container_end[]`
Other elements can be embedded in this element. Scrollbar must be placed manually.
* Drop genericobject.{cpp,h}
This file is not for generic object but for ActiveObject message passing.
Put ownership of the various commands to the right objects and cleanup the related code.
* Protect ServerActiveObject::m_messages_out
* typo fix
Safety-guards for CSM callbacks to abort on a bad implementation
Only run callbacks when the mods are loaded (and with it: builtin)
Duplication checks inside constructors
This change reduces the amount of sent data towards clients. Inventory lists that are already known to the player are skipped, saving quite some data over time.
Raises protocol version to 38 to ensure correct backwards-compatible code.
Update the profiler names to make more sense of what they actually represent
Move the profiler code from header to its source file
Use monospace font to align lines
Format the statistics line to align better with surrounding values
Refresh the profiler each 3 seconds (roughly)
* Optimize packet construction functions
Some of the functions that construct packets in
connection.cpp are using a const reference to get the raw
packet data to package and others use a value passed
parameter to do that. The ones that use the value passed
parameter suffer from performance hit as the rather bulky
packet data gets a temporary copy when the parameter is
passed before it lands at its final destination inside the
newly constructed packet. The unnecessary temporary copy
hurts quite badly as the underlying class (SharedBuffer)
actually allocates the space for the data in the heap.
Fix the performance hit by converting all of these value
passed parameters to const references. I believe that this
is what the author of the relevant code actually intended
to do as there is a couple of packet construction helper
functions that already use a const reference to get the
raw data.
* Optimize packet sender thread class
Most of the data sending methods of the packet sender thread
class use a value passed parameter for the packet data to be
sent. This causes the rather bulky data to be allocated on
the heap and copied, slowing the packet sending down. Convert
these parameters to const references to avoid the performance
hit.
* Optimize packet receiver thread class
The packet receiver and processor thread class has many
methods (mostly packet handlers) that receive the packed data
by value. This causes a performance hit that is actually
worse than the one caused by the packet sender methods
because the packet is first handed to the processPacket
method which looks at the packet type stored in the header
and then delegates the actual handling to one of the
handlers. Both, processPacket and all the handlers get the
packet data by value, leading to at least two unnecessary
copies of the data (with malloc and all the slow bells and
whistles of bulky classes).
As there already is a few methods that use a const reference
parameter for the packet data, convert all this value passed
packets to const references.
The "what" parameter is being passed by value, most likely by
accident as the type is "const std::string". Convert it to a
reference by adding the missing "&".
* Drop the ID mapper, use a big u64 instead. This will permit to resync server ids properly with the manager code
* Modernize some code parts (std::unordered_map, auto)
* generate id on client part on U32_MAX + 1 ids, lower are for server ids
