Multithreading support for Lua

Effil

Linux + MacOS	Windows

Effil is a multithreading library for Lua. It allows to spawn native threads and safe data exchange. Effil has been designed to provide clear and simple API for lua developers.

Effil supports lua 5.1, 5.2, 5.3 and LuaJIT. Requires C++14 compiler compliance. Tested with GCC 4.9+, clang 3.8 and Visual Studio 2015.

2. cd effil && mkdir build && cd build
3. cmake .. && make install
4. Copy effil.so to your project.

From lua rocks

luarocks install effil

Quick guide

As you may know there are not much script languages with real multithreading support (Lua/Python/Ruby and etc has global interpreter lock aka GIL). Effil solves this problem by running independent Lua VM instances in separate native threads and provides robust communicating primitives for creating threads and data sharing.

Effil library provides three major abstractions:

1. effil.thread - provides API for threads management.
2. effil.table - provides API for tables management. Tables can be shared between threads.
3. effil.channel - provides First-In-First-Out container for sequential data exchange.

And bunch of utilities to handle threads and tables as well.

Examples

Spawn the thread

local effil = require("effil")

function bark(name)
    print(name .. " barks from another thread!")
end

-- run funtion bark in separate thread with name "Spaky"
local thr = effil.thread(bark)("Sparky")

-- wait for completion
thr:wait()

Output: Sparky barks from another thread!

Sharing data with effil.channel

local effil = require("effil")

-- channel allow to push data in one thread and pop in other
local channel = effil.channel()

-- writes some numbers to channel
local function producer(channel)
    for i = 1, 5 do
        print("push " .. i)
        channel:push(i)
    end
    channel:push(nil)
end

-- read numbers from channels
local function consumer(channel)
    local i = channel:pop()
    while i do
        print("pop " .. i)
        i = channel:pop()
    end
end

-- run producer
local thr = effil.thread(producer)(channel)

-- run consumer
consumer(channel)

thr:wait()

Output:

push 1
push 2
pop 1
pop 2
push 3
push 4
push 5
pop 3 
pop 4
pop 5

Sharing data with effil.table

effil = require("effil")

-- effil.table transfers data between threads
-- and behaves like regualr lua table
local storage = effil.table { string_field = "first value" }
storage.numeric_field = 100500
storage.function_field = function(a, b) return a + b end
storage.table_field = { fist = 1, second = 2 }

function check_shared_table(storage)
   print(storage.string_field)
   print(storage.numeric_field)
   print(storage.table_field.first)
   print(storage.table_field.second)
   return storage.function_field(1, 2)
end

local thr = effil.thread(check_shared_table)(storage)
local ret = thr:get()
print("Thread result: " .. ret)

Output:

first value
100500
1
2
Thread result: 3

Important notes

Effil allows to transmit data between threads (Lua interpreter states) using effil.channel, effil.table or directly as parameters of effil.thread.

• Primitive types are transmitted 'as is' by copy: nil, boolean, number, string
• Functions are dumped using lua_dump. Upvalues are captured according to the rules.
  • C functions (for which lua_iscfunction returns true) are transmitted just by a pointer using lua_tocfunction (in original lua_State) and lua_pushcfunction (in new lua_State).
    caution: in LuaJIT standard functions like tonumber are not real C function, so lua_iscfunction returns true but lua_tocfunction returns nullptr. Due to that we don't find way to transmit it between lua_States.
• Userdata and Lua threads (coroutines) are not supported.
• Tables are serialized to effil.table recursively. So, any Lua table becomes effil.table. Table serialization may take a lot of time for big table. Thus, it's better to put data directly to effil.table avoiding a table serialization. Let's consider 2 examples:

-- Example #1
t = {}
for i = 1, 100 do
   t[i] = i
end
shared_table = effil.table(t)

-- Example #2
t = effil.table()
for i = 1, 100 do
   t[i] = i
end

In the example #1 we create regular table, fill it and convert it to effil.table. In this case Effil needs to go through all table fields one more time. Another way is example #2 where we firstly created effil.table and after that we put data directly to effil.table. The 2nd way pretty much faster try to follow this principle.

Blocking and nonblocking operations:

All operations which use time metrics can be blocking or non blocking and use following API: (time, metric) where metric is time interval like 's' (seconds) and time is a number of intervals.

Example:

• thread:get() - infinitely wait for thread completion.
• thread:get(0) - non blocking get, just check is thread finished and return
• thread:get(50, "ms") - blocking wait for 50 milliseconds.

List of available time intervals:

• ms - milliseconds;
• s - seconds (default);
• m - minutes;
• h - hours.

All blocking operations (even in non blocking mode) are interruption points. Thread hanged in such operation can be interrupted by invoking thread:cancel() method.

Example

local effil = require "effil"

local worker = effil.thread(function()
    effil.sleep(999) -- worker will hang for 999 seconds
end)()

worker:cancel(1) -- returns true, cause blocking operation was interrupted and thread was cancelled

Function's upvalues

Working with functions Effil serializes and deserializes them using lua_dump and lua_load methods. All function's upvalues are stored following the same rules as usual. If function has upvalue of unsupported type this function cannot be transmitted to Effil. You will get error in that case.

Working with function Effil can store function environment (_ENV) as well. Considering environment as a regular table Effil will store it in the same way as any other table. But it does not make sence to store global _G, so there are some specific:

• Lua = 5.1: function environment is not stored at all (due to limitations of lua_setfenv we cannot use userdata)
• Lua > 5.1: Effil serialize and store function environment only if it's not equal to global environment (_ENV ~= _G).

Thread cancellation and pausing

The effil.thread can be paused and cancelled using corresponding methods of thread object thread:cancel() and thread:pause().
Thread that you try to interrupt can be interrupted in two execution points: explicit and implicit.

• Explicit points are effil.yield()

  Example of explicit interruption point

  local thread = effil.thread(function()
     while true do
        effil.yield()
     end
     -- will never reach this line
  end)()
  thread:cancel()

• Implicit points are lua debug hook invocation which is set using lua_sethook with LUA_MASKCOUNT.
  Implicit points are optional and enabled only if thread_runner.step > 0.

  Example of implicit interruption point

  local thread_runner = effil.thread(function()
     while true do
     end
     -- will never reach this line
  end)
  thread_runner.step = 10
  thread = thread_runner()
  thread:cancel()

• Additionally thread can be cancelled (but not paused) in any blocking or non-blocking waiting operation.

  Example

  local channel = effil.channel()
  local thread = effil.thread(function()
     channel:pop() -- thread hangs waiting infinitely
     -- will never reach this line
  end)()
  thread:cancel()

How does cancellation works?
When you cancel thread it generates lua error with message "Effil: thread is cancelled" when it reaches any interruption point. It means that you can catch this error using pcall but thread will generate new error on next interruption point.
If you want to catch your own error but pass cancellation error you can use effil.pcall().
Status of cancelled thread will be equal to cancelled only if it finished with cancellation error. It means that if you catch cancellation error thread may finished with completed status or failed status if there will be some another error.

API Reference

Thread

effil.thread is the way to create a thread. Threads can be stopped, paused, resumed and cancelled. All operation with threads can be synchronous (with optional timeout) or asynchronous. Each thread runs with its own lua state.

Use effil.table and effil.channel to transmit data over threads. See example of thread usage here.

runner = effil.thread(func)

Creates thread runner. Runner spawns new thread for each invocation.

input: func - Lua function

output: runner - thread runner object to configure and run a new thread

Thread runner

Allows to configure and run a new thread.

thread = runner(...)

Run captured function with specified arguments in separate thread and returns thread handle.

input: Any number of arguments required by captured function.

output: Thread handle object.

runner.path

Is a Lua package.path value for new state. Default value inherits package.path form parent state.

runner.cpath

Is a Lua package.cpath value for new state. Default value inherits package.cpath form parent state.

runner.step

Number of lua instructions lua between cancelation points (where thread can be stopped or paused). Default value is 200. If this values is 0 then thread uses only explicit cancelation points.

Thread handle

Thread handle provides API for interaction with thread.

status, err, stacktrace = thread:status()

Returns thread status.

output:

• status - string values describes status of thread. Possible values are: "running", "paused", "cancelled", "completed" and "failed".
• err - error message, if any. This value is specified only if thread status == "failed".
• stacktrace - stacktrace of failed thread. This value is specified only if thread status == "failed".

... = thread:get(time, metric)

Waits for thread completion and returns function result or nothing in case of error.

input: Operation timeout in terms of time metrics

output: Results of captured function invocation or nothing in case of error.

thread:wait(time, metric)

Waits for thread completion and returns thread status.

input: Operation timeout in terms of time metrics

output: Returns status of thread. The output is the same as thread:status()

thread:cancel(time, metric)

Interrupts thread execution. Once this function was invoked 'cancellation' flag is set and thread can be stopped sometime in the future (even after this function call done). To be sure that thread is stopped invoke this function with infinite timeout. Cancellation of finished thread will do nothing and return true.

input: Operation timeout in terms of time metrics

output: Returns true if thread was stopped or false.

thread:pause(time, metric)

Pauses thread. Once this function was invoked 'pause' flag is set and thread can be paused sometime in the future (even after this function call done). To be sure that thread is paused invoke this function with infinite timeout.

input: Operation timeout in terms of time metrics

output: Returns true if thread was paused or false. If the thread is completed function will return false

thread:resume()

Resumes paused thread. Function resumes thread immediately if it was paused. This function does nothing for completed thread. Function has no input and output parameters.

Thread helpers

id = effil.thread_id()

Gives unique identifier.

output: returns unique string id for current thread.

effil.yield()

Explicit cancellation point. Function checks cancellation or pausing flags of current thread and if it's required it performs corresponding actions (cancel or pause thread).

effil.sleep(time, metric)

Suspend current thread.

input: time metrics arguments.

effil.hardware_threads()

Returns the number of concurrent threads supported by implementation. Basically forwards value from std::thread::hardware_concurrency.
output: number of concurrent hardware threads.

status, ... = effil.pcall(func, ...)

Works exactly the same way as standard pcall except that it will not catch thread cancellation error caused by thread:cancel() call.

input:

• func - function to call
• ... - arguments to pass to functions

output:

• status - true if no error occurred, false otherwise
• ... - in case of error return one additional result with message of error, otherwise return function call results

Table

effil.table is a way to exchange data between effil threads. It behaves almost like standard lua tables. All operations with shared table are thread safe. Shared table stores primitive types (number, boolean, string), function, table, light userdata and effil based userdata. Shared table doesn't store lua threads (coroutines) or arbitrary userdata. See examples of shared table usage here

Notes: shared tables usage

Use Shared tables with regular tables. If you want to store regular table in shared table, effil will implicitly dump origin table into new shared table. Shared tables always stores subtables as shared tables.

Use Shared tables with functions. If you store function in shared table, effil implicitly dumps this function and saves it as string (and it's upvalues). All function's upvalues will be captured according to following rules .

table = effil.table(tbl)

Creates new empty shared table.

input: tbl - is optional parameter, it can be only regular Lua table which entries will be copied to shared table.

output: new instance of empty shared table. It can be empty or not, depending on tbl content.

table[key] = value

Set a new key of table with specified value.

input:

• key - any value of supported type. See the list of supported types
• value - any value of supported type. See the list of supported types

value = table[key]

Get a value from table with specified key.

input: key - any value of supported type. See the list of supported types

output: value - any value of supported type. See the list of supported types

tbl = effil.setmetatable(tbl, mtbl)

Sets a new metatable to shared table. Similar to standard setmetatable.

input:

• tbl should be shared table for which you want to set metatable.
• mtbl should be regular table or shared table which will become a metatable. If it's a regular table effil will create a new shared table and copy all fields of mtbl. Set mtbl equal to nil to delete metatable from shared table.

output: just returns tbl with a new metatable value similar to standard Lua setmetatable method.

mtbl = effil.getmetatable(tbl)

Returns current metatable. Similar to standard getmetatable

input: tbl should be shared table.

output: returns metatable of specified shared table. Returned table always has type effil.table. Default metatable is nil.

tbl = effil.rawset(tbl, key, value)

Set table entry without invoking metamethod __newindex. Similar to standard rawset

input:

• tbl is shared table.
• key - key of table to override. The key can be of any supported type.
• value - value to set. The value can be of any supported type.

output: returns the same shared table tbl

value = effil.rawget(tbl, key)

Gets table value without invoking metamethod __index. Similar to standard rawget

input:

• tbl is shared table.
• key - key of table to receive a specific value. The key can be of any supported type.

output: returns required value stored under a specified key

effil.G

Is a global predefined shared table. This table always present in any thread (any Lua state).

effil = require "effil"

function job()
   effil = require "effil"
   effil.G.key = "value"
end

effil.thread(job)():wait()
print(effil.G.key) -- will print "value"

result = effil.dump(obj)

Truns effil.table into regular Lua table.

tbl = effil.table({})
effil.type(tbl) -- 'effil.table'
effil.type(effil.dump(tbl))  -- 'table'

Channel

effil.channel is a way to sequentially exchange data between effil threads. It allows to push message from one thread and pop it from another. Channel's message is a set of values of supported types. All operations with channels are thread safe. See examples of channel usage here

channel = effil.channel(capacity)

Creates a new channel.

input: optional capacity of channel. If capacity equals to 0 or to nil size of channel is unlimited. Default capacity is 0.

output: returns a new instance of channel.

pushed = channel:push(...)

Pushes message to channel.

input: any number of values of supported types. Multiple values are considered as a single channel message so one push to channel decreases capacity by one.

output: pushed is equal to true if value(-s) fits channel capacity, false otherwise.

... = channel:pop(time, metric)

Pop message from channel. Removes value(-s) from channel and returns them. If the channel is empty wait for any value appearance.

input: waiting timeout in terms of time metrics (used only if channel is empty).

output: variable amount of values which were pushed by a single channel:push() call.

size = channel:size()

Get actual amount of messages in channel.

output: amount of messages in channel.

Garbage collector

Effil provides custom garbage collector for effil.table and effil.channel (and functions with captured upvalues). It allows safe manage cyclic references for tables and channels in multiple threads. However it may cause extra memory usage. effil.gc provides a set of method configure effil garbage collector. But, usually you don't need to configure it.

Garbage collection trigger

Garbage collector perform it's work when effil creates new shared object (table, channel and functions with captured upvalues). Each iteration GC checks amount of objects. If amount of allocated objects becomes higher then specific threshold value GC starts garbage collecting. Threshold value is calculated as previous_count * step, where previous_count - amount of objects on previous iteration (100 by default) and step is a numerical coefficient specified by user (2.0 by default).

For example: if GC step is 2.0 and amount of allocated objects is 120 (left after previous GC iteration) then GC will start to collect garbage when amount of allocated objects will be equal to240.

How to cleanup all dereferenced objects

Each thread represented as separate Lua state with own garbage collector. Thus, objects will be deleted eventually. Effil objects itself also managed by GC and uses __gc userdata metamethod as deserializer hook. To force objects deletion:

1. invoke standard collectgarbage() in all threads.
2. invoke effil.gc.collect() in any thread.

effil.gc.collect()

Force garbage collection, however it doesn't guarantee deletion of all effil objects.

count = effil.gc.count()

Show number of allocated shared tables and channels.

output: returns current number of allocated objects. Minimum value is 1, effil.G is always present.

old_value = effil.gc.step(new_value)

Get/set GC memory step multiplier. Default is 2.0. GC triggers collecting when amount of allocated objects growth in step times.

input: new_value is optional value of step to set. If it's nil then function will just return a current value.

output: old_value is current (if new_value == nil) or previous (if new_value ~= nil) value of step.

effil.gc.pause()

Pause GC. Garbage collecting will not be performed automatically. Function does not have any input or output

effil.gc.resume()

Resume GC. Enable automatic garbage collecting.

enabled = effil.gc.enabled()

Get GC state.

output: return true if automatic garbage collecting is enabled or false otherwise. By default returns true.

Other methods

size = effil.size(obj)

Returns number of entries in Effil object.

input: obj is shared table or channel.

output: number of entries in shared table or number of messages in channel

type = effil.type(obj)

Threads, channels and tables are userdata. Thus, type() will return userdata for any type. If you want to detect type more precisely use effil.type. It behaves like regular type(), but it can detect effil specific userdata.

input: obj is object of any type.

output: string name of type. If obj is Effil object then function returns string like effil.table in other cases it returns result of lua_typename function.

effil.type(effil.thread()) == "effil.thread"
effil.type(effil.table()) == "effil.table"
effil.type(effil.channel()) == "effil.channel"
effil.type({}) == "table"
effil.type(1) == "number"

effil's Issues

при попытке собрать проект в MVS 2019 выходит ошибка Ошибка C1083

Здравствуйте, пытаюсь собрать effil через cmake, скачал репозиторий, скопировал sol в папку libs, указал папку с lua 5.3.5. при попытке собрать проект в MVS 2019 выходит ошибка
Ошибка C1083 Не удается открыть файл включение: sol.hpp: No such file or directory, effil C:\projects\effil\src\cpp\utils.h

Подскажите, пожалуйста, как решить эту проблему?

Когда проект соберется он будет effil.dll или effil.lua?

Lua api for shared tables

Library needs an API to work with SharedTables.

• Implement pairs/ipairs functions. -- done
• Analogue of setmetatable.
• effil.table.dumpkeys()

Change thread status while waiting data from effil.channel

It would be useful to change thread status when trying to channel:pop() empty channel. Smth like:

local channel = effil.channel()
function consumer() 
  local data = channel:pop()
end

local thread = effil.thread(consumer)()
function check_consuming()
  repeat
    local status, err, trace = thread:status()
  until status == "paused" -- or better decouple from thread:pause()
end

Fix&Simplify threads implementation

1. Get rid of active waiting in LuaThread::wait and luaHook. Use conditional variable or mutex instead.
2. Get rid from detach. Use implicit detach.
3. A-B-A problem. Cancel then resume is may be ok (!!!).
4. May be get rid of ThreadFactory. Now logic is quite complicated 😟. ThreadFactory just captures this state variable and provide some configuration. Why not to hide it in LuaThread? LuaThread::luaHook and LuaThread::work have to be free functions!

Add explicit cancellation point

Complete documentation for v1.0

Race condition between GCObject creation and GC garbage collecting

For example:
stored-object.cpp:

  SharedTable table = GC::instance().create<SharedTable>();
  ...
  return std::make_unique<GCObjectHolder<SharedTable>>(table.handle());

When we go out of scope of this function the table which currently is the only one hard link to the new GCObject will be destroyed and GC may collect this object before we start use it.

Cache string.dump and loadstring invokation

Each time when function is converted to StoredObject and when it's converted back we call string.dump and loadstring. We think that it can be optimized by cache. This cache should be individual for each state/thread.

Add Lua API for GC

Analize and provide Lua API for internal GC (use Lua's GC API as an example)

Where are effil.lua, libeffil.so/libeffil.dylib?

I am building a large Singularity container and it takes hours to make it. Before I install effil I would like to know where are the files effil.lua, libeffil.so/libeffil.dylib so that I can put a command in my script to copy those files into another location so that I can access them once the container is built. Would you please tell me where those files are once I compile effil so that I won't have to spend another couple of hours finding them and making the container again? Are they gonna be in the main effil folder?

Another question: By copying those files to my project, do you mean I should simply do cp effil.lua libeffil.so libeffil.dylib myProjectDir/?

Thank you

Inheritance in effil tables

Hi!
I'd like to use class inheritance with effil tables.
This works well:

globals = {}
globals.input = {}
globals.inputListPrototype = { protoFun1 = function(self) print('protoFun1') end, protoFun2 = function(self) print('protoFun2') end } 
setmetatable(globals.input, {__index = globals.inputListPrototype})
type(globals.input.protoFun1)

The same version with an effil table:

effil = require('effil')
globals = effil.table()
globals.input = {}
globals.inputListPrototype = { protoFun1 = function(self) print('protoFun1') end, protoFun2 = function(self) print('protoFun2') end } 
effil.setmetatable(globals.input, {__index = globals.inputListPrototype})
effil.type(globals.input.protoFun1)

Gives error:

attempt to call a table
stack traceback:
        [C]: in ?
        [C]: in metamethod '__index'
        stdin:1: in main chunk
        [C]: in ?

Why? How can I fix this? Thanks in advance!

Documentation for "Upvalues" feature

Cover new functionality - function upvalues support

Documentation: use HTTPS in git clone for installation

Hi, just a heads up. The docs say to do this to install:

$ git clone --recursive [email protected]:effil/effil.git effil                                                                                                         09:06:15
Cloning into 'effil'...
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

It should work for everyone without further configuration if you do:

git clone --recursive https://github.com/effil/effil.git effil

Switch CI to new Xcode 10.x

Serialize table's metatable as well

First place:

t = effil.table(setmetatable({}, {}))
effil.getmetatable(t) -- should no be nil

Second place:

t = effil.setmetatable({}, {})
getmetatable(effil.dump(t)) -- should no be nil

Extend CI to support LuaJIT2.1

We need to extend travis CI config and adapt tests/Effil to work with LuaJIT2.1

Save stacktrace for failed thread

Installation instructions seem to be outdated

In README.md it's mentioned that you have to do the following to use Effil:

Copy effil.lua and libeffil.so/libeffil.dylib to your project.

This doesn't seem correct since CMake only creates 1 DLL (at least on Windows).

Threads priority

It would be nice if effil will allow to set priority for new thread.
It looks not so complicated to implement.

How to use next() with effil?

I have a program in which I need to set the metatable so that pairs() does not iterate over functions. Something like this seems to work OK with normale tables:

local mt = { -- metatable
    __pairs = function(t) -- do NOT iterate with pairs over functions!
            local k=nil
            return function ()
                local v
                repeat k,v = next(t,k) until type(v) ~= 'function' or k == nil
                return k,v
            end
        end
}
setmetatable({}, mt)

However when setting the metatable for an effil table (effil.setmetatable) I have the following error:

bad argument #1 to 'next' (table expected, got sol.effil::SharedTable*)

How can I make this work? Thanks in advance!

git clone --recursive [email protected]:effil/effil.git effil && cd effil && mkdir build && cd build && cmake .. && make install

userdata

Hello

Is it planned to manage userdata ? I need to use socket (tls) and separate incoming data and sent data.
Unfortunately, socket return userdata and I am blocked

Best regards
Julien

Compile and test on windows

Should work with VS2105.

Make channels iteration easier

It would be nice if I can write code like this:

local channel = effil.channel()
-- fill channel
for value in channel:iterate() do
    print(value)
end

Support table as value of __index in metatable

implement __index = {} support in effil metatable.

как встроить новый поток в код с++, чтобы функция foo запускалась в новом потоке?

Очень восхищен Вашей библиотекой многопоточности Effil в lua. Возник вопрос: как встроить новый поток в код с++, чтобы функция foo запускалась в новом потоке? Очень хочу разобраться в механизме. Буду очень рад Вашему ответу. Спасибо.
`
#include
#include<lua.hpp>
#include<threading.h>
using namespace std;
using namespace sol;
using namespace effil;

const char* LUA =
R"(
foo()
)";
int foo(lua_State* L) {
cout << "hi foo c++" << endl;
return 0;
};

int embeds_sol(lua_State* L) {
// start using sol with a pre-existing system
state_view lua(L); // non-owning
// runner = thread(foo);
Thread::exportAPI(lua);
lua.open_libraries(lib::base, lib::package); // открыть доп.библиотеки.
lua.set("foo", foo); // вариант 2.

//Thread::resume();
lua.script(LUA);

return 0; // все, что требуется для работы с необработанной функцией.

};

int main(int argc, char* argv[]) {
lua_State* L = luaL_newstate();
luaL_openlibs(L);
embeds_sol(L);
lua_close(L);

return 0;

};

Set cancellation debug hook asynchronously

lua_sethook looks async safe.
So all threads can be spawned without overhead.
We'd only need a lock to make sure that the state is not lua_close'd.

Thread pool implementation

We want to create a thread pool over out threads and channels. To do that we should perform research for proper implementation and API design.

speed test

how many messages per second? 500? 5000? 50000? 500000?

Nested inner/outer classes with effil

I am learning to create Lua5.3 classes, and am trying to obtain a structure like this: outerObject = {innerObject1, innerObject2, ...}, where both outerObject and innerObject have their own methods. Both should only contain objects, the methods should be defined in their respective class and inherited via the standard __index approach.

The following works fine without Effil:

innerClass = {
    someMethod = function(self) print('some inner method called') end
}

outerClass = {
    newObject = function(self, tab) -- Create a new inner object inheriting from innerClass
        local innerMetatable = {
            __index = function(_, key) return innerClass[key] end
        }
        setmetatable(tab, innerMetatable)
        return tab
    end,
    someMethod = function(self) print('some outer method called') end,
    someOtherMethod = function(self) print('some outer method called which exists only in outer') end
}

 -- Create the outer object inheriting from outerClass
outerMetatable = {
    __index = function(_, key) return outerClass[key] end
}
outer = {}
setmetatable(outer, outerMetatable)
for i,k in pairs(outer) do print(i, k) end -- outer is empty now

-- Create an inner object
outer.innerObject = outer:newObject({'some table or thing'})
print(outer.innerObject)    -- OK: a table
for i,k in pairs(outer) do print(i, k) end -- outer has a key-value pair, of course

outer:someMethod() -- Works
outer:someOtherMethod() -- Works
outer.innerObject:someMethod() -- Works

The same with the outer object as en Effil table:

effil = require('effil')

innerClass = {
    someMethod = function(self) print('some inner method called') end
}

outerClass = {
    newObject = function(self, tab) -- Create a new inner object inheriting from innerClass
        local innerMetatable = {
            __index = function(_, key) return innerClass[key] end
        }
        setmetatable(tab, innerMetatable)
        return tab
    end,
    someMethod = function(self) print('some outer method called') end,
    someOtherMethod = function(self) print('some outer method called which exists only in outer') end
}

 -- Create the outer object inheriting from outerClass
outerMetatable = {
    __index = function(_, key) return outerClass[key] end
}
outer = effil.table()
effil.setmetatable(outer, outerMetatable)
for i,k in pairs(outer) do print(i, k) end -- outer is empty now

-- Create an inner object
outer.innerObject = outer:newObject({'some table or thing'})
print(outer.innerObject)    -- NIL!!!
for i,k in effil.pairs(outer) do print(i, k) end    -- BUT IT IS NOT EMPTY!

outer:someMethod() -- Works
outer:someOtherMethod() -- Works
outer.innerObject:someMethod() -- Does not work! outer.innerObject is NIL!

How can I make nested classes work using Effil? Is there something fundamentally wrong with my approach?

Method to turn an effil.table into a normal table

Hi and thanks for effil!

Sometimes it's be nice to be able to turn an effil.table back into a normal table, for example when using external libraries that check for the type() of an input.

One can do this with a simple loop, bu it's a bit tedious (especially for nested tables). Can you provide a function to do this?

(if it's not there already and I missed it!)

Thanks!

очень нужно в файле запустить функцию в отдельной сопрограмме

спасибо большое за Вашу чудесную библиотеку. она здорово облегчает жизнь. смог ее собрать и запустить.
немного пришлось помучатся из-за своей неопытность.
Скажите, пожалуйста, есть lua плагин gta vice city. каждый lua файл имеет свое состояние. иногда очень нужно в файле запустить функцию в отдельной сопрограмме. например, жив ли пед, то есть поочередное приостановление и возобновление.

вот на этом пример.

local effil = require 'effil'
function foo()
    for i = 1, 3 do print("foo= "..i)
    end
end
function foo3()
    for i = 1, 3 do  print("foo3= ".. i)
    end
end
thr = effil.thread(foo)()

thr1 = effil.thread(foo3)()

thr:wait()
thr1:wait()

а вот для игры

require("lualoader/mod")
--model = VICE8
t = {}
function funs(ped, m)
 player = findplayer()-- получить игрока
 x,y,z =getcoordinates_on_y(player,5)-- получить координаты на 5 м впереди.
 man = Createped(ped,x,y,z) 
 mar = create_marker_actor(man) -- создать маркер педа.
while true do 
 if 0 == gethealth(man)
 then  
 printmessage(m, 1500,1)
 remove_ped(man)
 removemarker(mar)-- удалить маркер над педом.
 break
 end
end
end
function main()
while lualoader == nil do
 wait()
 player = findplayer()-- получить игрока
 if Keypress(VK_G)
 then 
 newthread(funs,"BMYBB","remove ped")
 end 
 if Keypress(VK_H)
 then 
  Giveweaponped(player,300,"colt45","ruger","uzi")-- дать педу оружие. 
 end 
 end  
 end

Get rid of "gc.get" method usage

Do not save GCObjects in StoredObjects by handle (or only by handle) store a raw pointer as well, so gc.get will no be needed

Function to retrieve number of hardware threads

Or at least some estimate.

Atomic variable for numbers and bools

Make research about it performance and compare with regular variables + mutexes

Sleep a thread

Hello
I try to sleep a thread with socket.sleep or socket.select(nil, nil, x) but, the only way I found is to use os.execute("sleep x") where x is a number as follow:

local effil = require("effil")

-- channel allow to push data in one thread and pop in other
local channel = effil.channel()

-- writes some numbers to channel
function producer(channel)
    for i = 1, 5 do
        print("push " .. i)
        channel:push(i)
        os.execute("sleep " .. tostring(i))
    end
    channel:push(nil)
end

-- read numbers from channels
local function consumer(channel)
    local i = channel:pop()
    while i do
        print("pop " .. i)
        i = channel:pop()
    end
end

-- run producer
local thr = effil.thread(producer)(channel)

-- run consumer
consumer(channel)

thr:wait()

So, the code is bad. Is there another solution ?
Thank for your help and nice job for effil

Best regards
Julien

Upvalues support

Implement upvalues support for all functions used in Effil. If upvalue is Effil's Stored object then we just copy it.
HELP: what to do with regular table: serialize or ignore? If we will just serialize it it can be a problem if some upvalue is _G table.

Call __index only if value is not presented in table

Like in Lua we should call __index only if key is not presented in main table

Add spin-mutex Lua API

• Standalone mutex API
• Explicit locks for SharedTable (and internal recursive spin-mutex)

Userdata types identification

• Search for opportunities to determine type of Lua userdata
• Modify StoredObject's userdata handling principles based on research results

Submodule instruction is missing from readme

I spent some time trying to find sol library as a dynlib on mac before realizing it is actually referenced as a submodule on this repo.

I propose to put a git submodule update --init instruction on README.md a submodule made the submodule step explicit in the README so new people can have a easier time.

(I actually already have a pull request ready, just following CONTRIBUTING.md, and waiting for confirmation if it's really an issue :) )
