bd1766e448 Improve the LuaController
Changes:
  * Stops code after a certain number of instructions.
  * Allows functions, due to instruction counting.
  * Allows loops and goto with non-JIT Lua (LuaJIT doesn't count looping as an instruction, allowing infinite loops), due to instruction counting.
  * Removes string matching functions as they can be slow.
  * Adds some safe functions.
  * Limits the amount of printing that can be done (to prevent console flooding).
  * Code cleanup.
  * More...

d325292291 use the right mesecon:receptor_* call for on/off blinkyplant 2014-09-01 21:12:11 -04:00
Vanessa Ezekowitz
1ebd50ac75 use one ABM for blinkyplant instead of two.
using two ABMs allows the engine to desynchronize them, which makes the
duty cycle unpredictable.

e5896076fe Make sure #160 cannot be exploited to make servers crash.
This is not exactly a fix for the issue, because extremely
large circuits (3000+ conductors) still won't work with this applied.
This simply aborts any execution if there is the danger of a stack overflow.

b64fea4f70 Don't allow non-inventory items as ingredients
Some mesecon wires (the turned-on nodes) that were
not_in_creative_inventory and should never appear in an actual inventory
were also mesecon_conductor_craftable.  This is liable to make a craft
guide show them as potential ingredients, due to the use of the group
in recipes.

f1eaee2281 fix programming microcontroller through form
The handling of the "quit" pseudo-field meant that the microcontroller
couldn't be programmed with explicit code, only with the examples.
The "quit" can actually be ignored: what matters for programming the
controller is whether the "code" field was supplied.

300abcb587 Fix #155 (option 2 used). Remove non-ActionQueue system. Enable overheat for more than 20 actions per second on lua- / microcontrollers and gates.
Fix a bug where a burnt luacontroller didn't have the correct pin-states as the burnt controller does not register any changes from outside.

1f66687580 Fix bug that made delayers oscillate their input port
when powering off the delayer faster than the delay time.
Actually, delayers should have never worked since the ActionQueue update as
they always used the default rules for their output, which is obviously nonsense.

1852e967a9 Send changesignals for placed receptors when not powered, make on_placenode code more readable
with comments. Also fixes a bug of lua- / microcontrollers not being updated when pushed by a
piston.
This could cause some bugs, even though I haven't found any while testing as it is a very core part of mesecons.

3d2cfeace8 Fix #83 (experimental)
Why did we actually put the update action in a queue again? Whatever issue it that was for, I couldn't reproduce it.
Propably the ActionQueue fixed that...?

9eda62df7b Add timer() function/event (node timer based) to luacontroller
This adds a timer(<seconds>) function, which causes an event of type
"timer" to be fired after that many seconds has elapsed.

Because it's node timer based, it works properly across server restarts
and block unloading. Thus, simplest example, a blinky plant replacement
with a 10 second period:

if event.type == "program" then
  timer(10)
elseif event.type == "timer" then
  port.a = not port.a
  timer(10)
end

5002315ec9 Send digiline messages after luacontroller execution
In the same way as for port settings, this queues up digiline messages
sent during the luacontroller's execution, and sends them afterwards.
This solves many problems, but one example:

1. Send a message, and receive a reply from another device.
2. While handling the reply event (effectively a nested invocation
   on the same luacontroller) make a change to memory
3. Notice that the memory change has no effect, because after
   completion of the reply handling, it stores the memory, but then
   the original invocation completes and overwrites it with it's
   own earlier copy of the same memory.

8a71f51b26 Merge branch 'actionqueue'
This introduces the ActionQueue, a new kind of MESECONS_GLOBALSTEP.
Circuits using delayers will now resume when restarting the server.
Also, large circuits should automatically resume if parts of them are
in unloaded chunks.
Old circuits e.g. using gates will not resume when mesecons is updated,
which means you have to restart them once. But after that, it should work
just like it used to.
This will fix a lot of stuff but may also introduce some new bugs.
So please report them!

f1211f7dae Add ActionQueue priority system
This makes effectors nearer to the source of the action (the receptor) update first.

This defines behaviour for this piston circuit: http://i.imgur.com/9Pp2Mzb.png
And defines, that this memory circuit does not work from this direction: http://i.imgur.com/jJn0aFh.png
But it will work when using the switch from the other side: http://i.imgur.com/nvw0oZB.png

Only if two effectors have the same distance, there is nothing we can do about it, behaviour is not defined.
"Distance" is determined by the stack size of recursions in turnon / turnoff.
Priorities are between 0 (lowest) and 1 (highest).
