2016-12-31Allow water turbines to work with river water (fixes #294)Carter Kolwey
This also makes turbines compatible with any liquid that is in the `water` group and has `liquidtype == "flowing"`.
2016-12-31Luacontroller: Fix bugs in 703e6fda, no more functions as keysJeija
Thanks to @ShadowNinja for reporting this Make sure functions that are keys in tables and functions inside nested tables also get removed when using digiline_send.
2016-12-28Luacontroller: Restrict digiline messagesJeija
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.

2016-09-04Never postpone action_on or action_offJeija
There is no more need for that since VoxelManip caching makes sure we always get an answer to get_node_force.

2016-08-31Duplicate unhash_blockpos code to legacy.luaJeija
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.
2016-08-30Remove some long unused legacy codeJeija
The change that required this compatibility layer happened in 2014, so other mods have had a lot of time to update.
2016-08-30Small cleanups in `internal.lua`, move forceloading reversal to legacyJeija
2016-08-30Greatly improve performance by making use of VoxelManips in turnoffJeija
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.
2016-08-30Further simplification of turnon/turnoffJeija
2016-08-24Simplify turnon/turnoff.Christopher Head
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.
2016-08-24Use VM transactions for conductor state changes.Christopher Head
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.
2016-08-24Implement VoxelManipulator-based transactions.Christopher Head
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.
2016-08-24Use VoxelManipulators for get_node_force.Christopher Head
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.
2016-08-23Split wires into their own mod, introduce autoconnect hooksCarter Kolwey
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.

2016-04-02Disable JIT optimization for user code and allow string.find in plain modePedro Gimeno
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`.

2016-02-19Force-load areas with mesecon usageJeija
This is a major speedup for large mesecon machines / structures. Force-loaded areas are stored in a file to be persistent over server reboots. By default, areas are unloaded after 10 minutes (600s) without usage, this can be customized with the mesecon.forceload_timeout setting. Please turn max_forceloaded_blocks up for better performance.
