46cbc76988 make "on" water turbine animated!
This uses a fairly simple trick: the textures are animated, while the
model is static and has a number of rotated copies of the parts that are
seen to move (four copies of the blades, eight copies of the top/bottom
and their edges).  The opaque parts of the textures then decide which of
those faces' copies are visible in each frame.

1bd936ad8c Properly handle rotation of buttons / levers
Buttons and levers can now also be pointed upwards / downwards which will make them connect to corresponding up / down receivers. You will need to use the screwdriver for this.

Receivers cannot be rotated using the screwdriver anymore.

703e6fdadb Luacontroller: Restrict digiline messages
Restrict maximum length of messages to 50.000 characters and disable sending functions or table references over the wire. Restrict types of channel variable to string, number or boolean.

The missing length restriction made DoS-like attacks possible by overflowing memory using string concatenation. Thanks to gamemanj for disclosing this issue.

95fedc88bc Never postpone action_on or action_off
There is no more need for that since VoxelManip caching makes sure we
always get an answer to get_node_force.

54efc64558 Duplicate unhash_blockpos code to legacy.lua
Duplicating that small piece of code seems like a better idea than
putting the undo-forceloading code back into util.lua. This way, it is
easier to remember to remove that unneccesary code after a couple of
months / years, when people have transitioned. This also means we can
make changes to the code in util.lua without breaking old code.

e561be7fa3 Greatly improve performance by making use of VoxelManips in turnoff
Instead of seperately looking for onstate receptors along equipotential
sections of the circuit before turning off, do that while already
modifying the VoxelManip. In case an onstate receptor is found, discard
the VoxelManip cache, otherwise commit it after turnoff is completed.

89153f6909 Further simplification of turnon/turnoff 2016-08-30 18:24:08 +02:00

8e6536ca2e
Simplify turnon/turnoff.
It is no longer possible for get_node_force to return nil if the target
location does, in fact, exist, because a VM will always be able to load
it (whereas a forceload might not, due to exhaustion of forceload
resources). So it is no longer necessary to handle get_node_force
returning nil by deferring processing.

Use VM transactions for conductor state changes.
VoxelManipulator-based transactions are used to hopefully speed up
scanning and replacing of networks of conductors when receptors start or
stop driving signals into them.

Implement VoxelManipulator-based transactions.
Rather than calling out through the Lua-to-C API for each node that
needs to be read or written, a group of map reads (and optionally
writes) can be grouped into a transaction. Access to map data within the
transaction is provided at high speed by means of VoxelManipulators.
Once the reads and writes are finished, the transaction can be committed
or aborted.

Use VoxelManipulators for get_node_force.
A VoxelManipulator, when asked to read a mapblock, in addition to making
that mapblock available to the caller, also pulls it into the server’s
map cache, thus making get_node calls in the immediate future succeed.

This has the dual advantages that not every mapblock containing a
Mesecons circuit need remain loaded at all times (rather mapblocks can
be loaded on demand as signals are sent), and that the server need not
bother running ABMs and ticking entities within those mapblocks that are
loaded due to Mesecons signalling.

912f17f335 Split wires into their own mod, introduce autoconnect hooks
The update_autoconnect function had to be abstracted away from the
default wires, any kind of wire can now register autoconnect hooks,
which should make having multiple different wire types much easier.

mesecons_mvps, mesecons_receiver and mesecons_random made use of
update_autoconnect, their code was also adapted. This also fixes a
receiver bug: If a receiver was placed with a onstate receptor next
to it (but not the wall lever / button that caused the receiver to
appear) the receiver didn't turn on in the past.

Also move documentation for mesecon wire into mesecons_wire.

b487783c23 Disable JIT optimization for user code and allow string.find in plain mode
Disabling LuaJIT for user code enables normal working of debug.sethook() even for loops. The drawback is that that code will run more slowly.

The fourth parameter of string.find indicates whether the second parameter should be interpreted literally (true) or as a pattern (false). Allowing patterns enables DoS attacks, but it's possible to
allow literal matching with little effort, by disallowing the function only if the fourth parameter (plain mode) is not `true`.
