+Added:
+
+- THREAD:newFunction(func,holup) -- A system threaded based variant to thread:newFunction(func,holup) works the same way. Though this should only be used for intensive functions! Calling a STfunction has a decent amount of overhead, use wisely. System threaded jobqueue may be a better choice depending on what you are planning on doing.
+- multi:loveloop() -- Handles the run function for love2d as well as run the multi mainloop.
+- multi.OnLoad(func) -- A special connection that allows you to connect to the an event that triggers when the multi engine starts! This is slightly different from multi.PreLoad(func) Which connects before any variables have been set up in the multi table, before any settings are cemented into the core. In most cases they will operate exactly the same. This is a feature that was created with module creators in mind. This way they can have code be loaded and managed before the main loop starts.
+- multi.OnExit(func) -- A special connection that allows you to connect onto the lua state closing event.
+
+package.path="?/init.lua;?.lua;"..package.path
+multi,thread = require("multi"):init()
+multi.OnExit(function(n)

+multi,thread = require("multi"):init()
+multi.OnExit(function(n)
+ print("Code Exited")
+end) -- The code finishing also triggers this event
+
+
+- thread enviroments are able to interact with threaded functions and wait when there is the presence of variables. Only works when creating "Globals" inside of a thread. The way the enviroment has been set up is that it sets your "Global" as a "GLocal" a global variable local to the threaded enviroment. This does not have the access speed benifits that using pure locals have.

+- love2d had an issue where threads crashing would break the mainloop
+- fixed bugs within the extensions.lua file for love threading
+- Modified the thread.* methods to perform better (Tables were being created each time one of these methods were called! Which in turn slowed things down. One table is modified to get things working properly)
+
+- thread.sleep()
+- thread.hold()
+- thread.holdFor()
+- thread.holdWithin()
+- thread.skip()
+- thread.kill()
+- thread.yield()
+
+
+
+Update 14.0.0 - Consistency, Additions and Stability
+
+Added:
+
+- multi.init() -- Initlizes the library! Must be called for multiple files to have the same handle. Example below
+- thread.holdFor(NUMBER sec, FUNCTION condition) -- Works like hold, but timesout when a certain amount of time has passed!
+- multi.hold(function or number) -- It's back and better than ever! Normal multi objs without threading will all be halted where threads will still run. If within a thread continue using thread.hold() and thread.sleep()
+- thread.holdWithin(NUMBER; cycles,FUNCTION; condition) -- Holds until the condition is met! If the number of cycles passed is equal to cycles, hold will return a timeout error
+- multi.holdFor(NUMBER; seconds,FUNCTION; condition) -- Follows the same rules as multi.hold while mimicing the functionality of thread.holdWithin
+Note: when hold has a timeout the first argument will return nil and the second atgument will be TIMEOUT, if not timed out hold will return the values from the conditions
+- thread objects now have hooks that allow you to interact with it in more refined ways!
+-- tObj.OnDeath(self,status,returns[...]) -- This is a connection that passes a reference to the self, the status, whether or not the thread ended or was killed, and the returns of the thread.
+-- tObj.OnError(self,error) -- returns a reference to self and the error as a string
+-- Limitations: only 7 returns are possible! This was done because creating and destroying table objects are slow. (The way the scheduler works this would happen every cycle and thats no good) Instead I capture the return values from coroutine.resume into local variables and only allowed it to collect 7 max.
+- thread.run(function) -- Can only be used within a thread, creates another thread that can do work, but automatically returns whatever from the run function -- Use thread newfunctions for a more powerful version of thread.run()
+- thread:newFunction(FUNCTION; func)
+-- returns a function that gives you the option to wait or connect to the returns of the function.
+-- func().wait() -- waits for the function to return works both within a thread and outside of one
+-- func().connect() -- connects to the function finishing
+-- func() -- If your function does not return anything you dont have to use wait or connect at all and the function will return instantly. You could also use wait() to hold until the function does it thing
+-- If the created function encounters an error, it will return nil, the error message!
+- special variable multi.NIL was added to allow error handling in threaded functions.
+-- multi.NIL can be used in to force a nil value when using thread.hold()
+- All functions created in the root of a thread are now converted to threaded functions, which allow for wait and connect features. Note: these functions are local to the function! And are only converted if they aren't set as local! Otherwise the function
+- lanes threads can now have their priority set using: sThread.priority =
+-- thread.Priority_Core
+-- thread.Priority_High
+-- thread.Priority_Above_Normal
+-- thread.Priority_Normal
+-- thread.Priority_Below_Normal
+-- thread.Priority_Low
+-- thread.Priority_Idle

-
- - love/lanesManager system threading integration has been reworked. Faster and cleaner code! Consistant code as well
Note: Using init allows you to get access to the thread handle. This was done because thread was modifying the global space as well as multi. I wanted to not modify the global space anymore.
internally most of your code can stay the same, you only need to change how the library is required. I do toy a bit with the global space, buy I use a variable name that is invalid as a variable name. The variable name is $multi. This is used internally to keep some records and maintain a clean space
Also when using intergrations things now look more consistant.

-local GLOBSL, THREAD = require("multi.integration.lanesManager").init() -- or whichever manager you are using
-local nGLOBAL, nTHREAD = require("multi.intergration.networkManager).inti()
-
Note: You can mix and match integrations together. You can create systemthreads within network threads, and you can also create cotoutine based threads within bothe network and system threads. This gives you quite a bit of flexibility to create something awesome.
Going forward:
-- Finish the rework of the networkManager - It “works”, but there are packet losses that I cannot explain. I do not know what is causing this at all. Ill fix when I figure it out!
- If all goes well, the future will contain quality of code features. I’ll keep an eye out for bugs
Update 13.1.0 Bug fixes and features added
Added:
-- Connections:Lock() — Prevents a connection object form being fired
- Connections:Unlock() — Removes the restriction imposed by conn:Lock()
- new fucntions added to the thread namespace
— thread.request(THREAD handle,STRING cmd,VARARGS args) — allows you to push thread requests from outside the running thread! Extremely powerful.
— thread.exec(FUNCTION func) — Allows you to push code to run within the thread execution block! - handle = multi:newThread() — now returns a thread handle to interact with the object outside fo the thread
— handle:Pause()
— handle:Resume()
— handle:Kill()
Fixed:
-- Minor bug with multi:newThread() in how names and functions were managed
- Major bug with the system thread handler. Saw healthy threads as dead ones
- Major bug the thread scheduler was seen creating a massive amount of ‘event’ causing memory leaks and hard crashes! This has been fixed by changing how the scheduler opperates.
- newSystemThread()’s returned object now matches both the lanes and love2d in terms of methods that are usable. Error handling of System threads now behave the same across both love and lanes implementations.
- looks like I found a typo, thread.yeild -> thread.yield
Changed:
-- getTasksDetails(“t”), the table varaiant, formats threads, and system threads in the same way that tasks are formatted. Please see below for the format of the task details
- TID has been added to multi objects. They count up from 0 and no 2 objects will have the same number
- thread.hold() — As part of the memory leaks that I had to fix thread.hold() is slightly different. This change shouldn’t impact previous code at all, but thread.hold() can not only return at most 7 arguments!
- You should notice some faster code execution from threads, the changes improve preformance of threads greatly. They are now much faster than before!
- multi:threadloop() — No longer runs normal multi objects at all! The new change completely allows the multi objects to be seperated from the thread objects!
- local multi, thread = require(“multi”) — Since coroutine based threading has seen a change to how it works, requring the multi library now returns the namespace for the threading interface as well. For now I will still inject into global the thread namespace, but in release 13.2.0 or 14.0.0 It will be removed!

-Update 13.0.0 Added some documentation, and some new features too check it out!
Quick note on the 13.0.0 update:
This update I went all in finding bugs and improving proformance within the library. I added some new features and the new task manager, which I used as a way to debug the library was a great help, so much so thats it is now a permanent feature. It’s been about half a year since my last update, but so much work needed to be done. I hope you can find a use in your code to use my library. I am extremely proud of my work; 7 years of development, I learned so much about lua and programming through the creation of this library. It was fun, but there will always be more to add and bugs crawling there way in. I can’t wait to see where this library goes in the future!
Fixed: Tons of bugs, I actually went through the entire library and did a full test of everything, I mean everything, while writing the documentation.
Changed:
-- A few things, to make concepts in the library more clear.
- The way functions returned paused status. Before it would return “PAUSED” now it returns nil, true if paused
- Modified the connection object to allow for some more syntaxial suger!
- System threads now trigger an OnError connection that is a member of the object itself. multi.OnError() is no longer triggered for a system thread that crashes!
Connection Example:
loop = multi:newTLoop(function(self)
- self:OnLoops() -- new way to Fire a connection! Only works when used on a multi object, bin objects, or any object that contains a Type variable
+ ["ProcessName"] = multi.root,
+ ["CyclesPerSecondPerTask"] = 3560300,
+ ["MemoryUsage"] = 1846, in KB returned as a number
+ ["ThreadCount"] = 1,
+ ["SystemLoad"] = 0, as a % 100 is max 0 is min
+ ["PriorityScheme"] = Round-Robin

It's been about half a year since my last update, but so much work needed to be done. I hope you can find a use in your code to use my library. I am extremely proud of my work; 7 years of development, I learned so much about lua and programming through the creation of this library. It was fun, but there will always be more to add and bugs crawling there way in. I can't wait to see where this library goes in the future!
+Fixed:
+
+- Tons of bugs, I actually went through the entire library and did a full test of everything, I mean everything, while writing the documentation.
+
+Changed:
+
+- A few things, to make concepts in the library more clear.
+- The way functions returned paused status. Before it would return "PAUSED" now it returns nil, true if paused
+- Modified the connection object to allow for some more syntaxial suger!
+- System threads now trigger an OnError connection that is a member of the object itself. multi.OnError() is no longer triggered for a system thread that crashes!
+
+Connection Example:
+loop = multi:newTLoop(function(self)
+ self:OnLoops() -- new way to Fire a connection! Only works when used on a multi object, bin objects, or any object that contains a Type variable
end,1)
loop.OnLoops = multi:newConnection()
loop.OnLoops(function()
- print("Looping")
+ print("Looping")
end)
multi:mainloop()
-Function Example:
func = multi:newFunction(function(self,a,b)
- self:Pause()
- return 1,2,3
+
+Function Example:
+func = multi:newFunction(function(self,a,b)
+ self:Pause()
+ return 1,2,3
end)
print(func()) -- returns: 1, 2, 3
print(func()) -- nil, true
-Removed:
-- Ranges and conditions — corutine based threads can emulate what these objects did and much better!
- Due to the creation of hyper threaded processes the following objects are no more!
— multi:newThreadedEvent()
— multi:newThreadedLoop()
— multi:newThreadedTLoop()
— multi:newThreadedStep()
— multi:newThreadedTStep()
— multi:newThreadedAlarm()
— multi:newThreadedUpdater()
— multi:newTBase() — Acted as the base for creating the other objects
These didn’t have much use in their previous form, but with the addition of hyper threaded processes the goals that these objects aimed to solve are now possible using a process
Fixed:
-- There were some bugs in the networkmanager.lua file. Desrtoy -> Destroy some misspellings.
- Massive object management bugs which caused performance to drop like a rock.
- Found a bug with processors not having the Destroy() function implemented properly.
- Found an issue with the rockspec which is due to the networkManager additon. The net Library and the multi Library are now codependent if using that feature. Going forward you will have to now install the network library separately
- Insane proformance bug found in the networkManager file, where each connection to a node created a new thread (VERY BAD) If say you connected to 100s of threads, you would lose a lot of processing power due to a bad implementation of this feature. But it goes further than this, the net library also creates a new thread for each connection made, so times that initial 100 by about 3, you end up with a system that quickly eats itself. I have to do tons of rewriting of everything. Yet another setback for the 13.0.0 release (Im releasing 13.0.0 though this hasn’t been ironed out just yet)
- Fixed an issue where any argument greater than 256^2 or 65536 bytes is sent the networkmanager would soft crash. This was fixed by increading the limit to 256^4 or 4294967296. The fix was changing a 2 to a 4. Arguments greater than 256^4 would be impossible in 32 bit lua, and highly unlikely even in lua 64 bit. Perhaps someone is reading an entire file into ram and then sending the entire file that they read over a socket for some reason all at once!?
- Fixed an issue with processors not properly destroying objects within them and not being destroyable themselves
- Fixed a bug where pause and resume would duplicate objects! Not good
- Noticed that the switching of lua states, corutine based threading, is slower than multi-objs (Not by much though).
- multi:newSystemThreadedConnection(name,protect) — I did it! It works and I believe all the gotchas are fixed as well.
— Issue one, if a thread died that was connected to that connection all connections would stop since the queue would get clogged! FIXED
— There is one thing, the connection does have some handshakes that need to be done before it functions as normal!
Added:
-- Documentation, the purpose of 13.0.0, orginally going to be 12.2.3, but due to the amount of bugs and features added it couldn’t be a simple bug fix update.
- multi:newHyperThreadedProcess(STRING name) — This is a version of the threaded process that gives each object created its own coroutine based thread which means you can use thread.* without affecting other objects created within the hyper threaded processes. Though, creating a self contained single thread is a better idea which when I eventually create the wiki page I’ll discuss
- multi:newConnector() — A simple object that allows you to use the new connection Fire syntax without using a multi obj or the standard object format that I follow.
- multi:purge() — Removes all references to objects that are contained withing the processes list of tasks to do. Doing this will stop all objects from functioning. Calling Resume on an object should make it work again.
- multi:getTasksDetails(STRING format) — Simple function, will get massive updates in the future, as of right now It will print out the current processes that are running; listing their type, uptime, and priority. More useful additions will be added in due time. Format can be either a string “s” or “t” see below for the table format
- multi:endTask(TID) — Use multi:getTasksDetails(“t”) to get the tid of a task
- multi:enableLoadDetection() — Reworked how load detection works. It gives better values now, but it still needs some work before I am happy with it
- THREAD.getID() — returns a unique ID for the current thread. This varaiable is visible to the main thread as well by accessing it through the returned thread object. OBJ.Id Do not confuse this with thread.* this refers to the system threading interface. Each thread, including the main thread has a threadID the main thread has an ID of 0!
- multi.print(…) works like normal print, but only prints if the setting print is set to true
- setting:
print enables multi.print() to work - STC: IgnoreSelf defaults to false, if true a Fire command will not be sent to the self
- STC: OnConnectionAdded(function(connID)) — Is fired when a connection is added you can use STC:FireTo(id,…) to trigger a specific connection. Works like the named non threaded connections, only the id’s are genereated for you.
- STC: FireTo(id,…) — Described above.

If you compare the benchmark from this version to last version you;ll notice a signifacant increase in performance.
Going forward:
-- Work on system threaded functions
- work on the node manager
- patch up bugs
- finish documentstion
Update 12.2.2 Time for some more bug fixes!
Fixed: multi.Stop() not actually stopping due to the new pirority management scheme and preformance boost changes.
Thats all for this update
Update 12.2.1 Time for some bug fixes!
Fixed: SystemThreadedJobQueues
-- You can now make as many job queues as you want! Just a warning when using a large amount of cores for the queue it takes a second or 2 to set up the jobqueues for data transfer. I am unsure if this is a lanes thing or not, but love2d has no such delay when setting up the jobqueue!
- You now connect to the OnReady in the jobqueue object. No more holding everything else as you wait for a job queue to be ready
- Jobqueues:doToAll now passes the queues multi interface as the first and currently only argument
- No longer need to use jobqueue.OnReady() The code is smarter and will send the pushed jobs automatically when the threads are ready
Fixed: SystemThreadedConnection
-- They work the exact same way as before, but actually work as expected now. The issue before was how i implemented it. Now each connection knows the number of instances of that object that ecist. This way I no longer have to do fancy timings that may or may not work. I can send exactly enough info for each connection to consume from the queue.
Removed: multi:newQueuer
-- This feature has no real use after corutine based threads were introduced. You can use those to get the same effect as the queuer and do it better too.
Going forwardGoing forward:
-- Will I ever finish steralization? Who knows, but being able to save state would be nice. The main issue is there is no simple way to save state. While I can provide methods to allow one to turn the objects into strings and back, there is no way for me to make your code work with it in a simple way. For now only the basic functions will be here.
- I need to make better documentation for this library as well. In its current state, all I have are examples and not a list of what is what.

-Update 12.2.0
Added:
-- multi.nextStep(func)
- Method chaining
- Priority 3 has been added!
- ResetPriority() — This will set a flag for a process to be re evaluated for how much of an impact it is having on the performance of the system.
- setting: auto_priority added! — If only lua os.clock was more fine tuned… milliseconds are not enough for this to work
- setting: auto_lowerbound added! — when using auto_priority this will allow you to set the lowbound for pirority. The defualt is a hyrid value that was calculated to reach the max potential with a delay of .001, but can be changed to whatever. Remember this is set to processes that preform really badly! If lua could handle more detail in regards to os.clock() then i would set the value a bit lower like .0005 or something like that
- setting: auto_stretch added! — This is another way to modify the extent of the lowest setting. This reduces the impact that a low preforming process has! Setting this higher reduces the number of times that a process is called. Only in effect when using auto_priotity
- setting: auto_delay added! — sets the time in seconds that the system will recheck for low performing processes and manage them. Will also upgrade a process if it starts to run better.
-- All methods that did not return before now return a copy of itself. Thus allowing chaining. Most if not all mutators returned nil, so chaining can now be done. I will eventually write up a full documentation of everything which will show this.

-Auto Priority works by seeing what should be set high or low. Due to lua not having more persicion than milliseconds, I was unable to have a detailed manager that can set things to high, above normal, normal, ect. This has either high or low. If a process takes longer than .001 millisecond it will be set to low priority. You can change this by using the setting autolowest = multi.Priority[PLevel] the defualt is low, not idle, since idle tends to get about 1 process each second though you can change it to idle using that setting.
Improved:
-- Performance at the base level has been doubled! On my machine benchmark went from ~9mil to ~20 mil steps/s.
Note: If you write slow code this library’s improbements wont make much of a difference. - Loops have been optimised as well! Being the most used objects I felt they needed to be made as fast as possible
I usually give an example of the changes made, but this time I have an explantion for multi.nextStep(). It’s not an entirely new feature since multi:newJob() does something like this, but is completely different. nextStep addes a function that is executed first on the next step. If multiple things are added to next step, then they will be executed in the order that they were added.
Note:
The upper limit of this libraries performance on my machine is ~39mil. This is simply a while loop counting up from 0 and stops after 1 second. The 20mil that I am currently getting is probably as fast as it can get since its half of the max performance possible, and each layer I have noticed that it doubles complexity. Throughout the years with this library I have seen massive improvements in speed. In the beginning we had only ~2000 steps per second. Fast right? then after some tweaks we went to about 300000 steps per second, then 600000. Some more tweaks brought me to ~1mil steps per second, then to ~4 mil then ~9 mil and now finally ~20 mil… the doubling effect that i have now been seeing means that odds are I have reach the limit. I will aim to add more features and optimize individule objects. If its possible to make the library even faster then I will go for it.
Update 12.1.0
Fixed:
-- bug causing arguments when spawning a new thread not going through
Changed:
-- thread.hold() now returns the arguments that were pass by the event function
- event objexts now contain a copy of what returns were made by the function that called it in a table called returns that exist inside of the object

-Note: Only if the first return is non-nil/false will any other returns be passed! So while variable b above is nil the string “We did it!” will not be passed. Also while this seems simple enough to get working, I had to modify a bit on how the scheduler worked to add such a simple feature. Quite a bit is going on behind the scenes which made this a bit tricky to implement, but not hard. Just needed a bit of tinkering. Plus event objects have not been edited since the creation of the EventManager. They have remained mostly the same since 2011
Going forward:
Contunue to make small changes as I come about them. This change was inspired when working of the net library. I was addind simple binary file support over tcp, and needed to pass the data from the socket when the requested amount has been recieved. While upvalues did work, i felt returning data was cleaner and added this feature.
Update: 12.0.0 Big update (Lots of additions some changes)
Note: After doing some testing, I have noticed that using multi-objects are slightly, quite a bit, faster than using (coroutines)multi:newthread(). Only create a thread if there is no other possibility! System threads are different and will improve performance if you know what you are doing. Using a (coroutine)thread as a loop with a
is slower than using a TLoop! If you do not need the holding features I strongly recommend that you use the multi-objects. This could be due to the scheduler that I am using, and I am looking into improving the performance of the scheduler for (coroutine)threads. This is still a work in progress so expect things to only get better as time passes! This was the reason threadloop was added. It binds the thread scheduler into the mainloop allowing threads to run much faster than before. Also the use of locals is now possible since I am not dealing with seperate objects. And finally, reduced function overhead help keeps the threads running better.
Added:
-nGLOBAL = require("multi.integration.networkManager").init()node = multi:newNode(tbl: settings)master = multi:newMaster(tbl: settings)multi:nodeManager(port)thread.isThread() — for coroutine based threads- New setting to the main loop, stopOnError which defaults to true. This will cause the objects that crash, when under protect, to be destroyed. So the error does not keep happening.
- multi:threadloop(settings) works just like mainloop, but prioritizes (corutine based) threads. Regular multi-objects will still work. This improves the preformance of (coroutine based) threads greatly.
- multi.OnPreLoad — an event that is triggered right before the mainloop starts
Changed:
-- When a (corutine based)thread errors it does not print anymore! Conect to multi.OnError() to get errors when they happen!
- Connections get yet another update. Connect takes an additional argument now which is the position in the table that the func should be called. Note: Fire calls methods backwards so 1 is the back and the # of connections (the default value) is the beginning of the call table
- The love2d compat layer has now been revamped allowing module creators to connect to events without the user having to add likes of code for those events. Its all done automagically.
- This library is about 8 years old and using 2.0.0 makes it seem young. I changed it to 12.0.0 since it has some huge changes and there were indeed 12 major releases that added some cool things. Going forward I’ll use major.minor.bugfix
- multi.OnError() is now required to capture errors that are thrown when in prorected mode.
Node:
-- node:sendTo(name,data)
- node:pushTo(name,data)
- node:peek()
- node:pop()
- node:getConsole() — has only 1 function print which allows you to print to the master.
Master:
-- master:doToAll(func)
- master:register(name,node,func)
- master:execute(name,node,…)
- master:newNetworkThread(tname,func,name,…)
- master:getFreeNode()
- master:getRandomNode()
- master:sendTo(name,data)
- master:pushTo(name,data)
- master:peek()
- master:pop()
- master:OnError(nodename, error) — if a node has an error this is triggered.
Bugs
-- Fixed a small typo I made which caused a hard crash when a (coroutine) thread crashes. This only happened if protect was true.
Going forward:
-- I am really excited to finally get this update out there, but left one important thing out. enabling of enviroments for each master connected to a node. This would allow a node to isolate code from multiple masters so they cannot interact with each other. This will come out in version 12.1.0 But might take a while due to the job hunt that I am currently going through.
- Another feature that I am on the fence about is adding channels. They would work like queues, but are named so you can seperate the data from different channels where only one portion of can see certain data.
- I also might add a feature that allows different system threads to consume from a network queue if they are spaned on the same physical machine. This is possible at the moment, just doesn’t have a dedicated object for handling this seamlessly. You can do this yourself though.
- Another feature that I am thinking of adding is crosstalk which is a setting that would allow nodes to talk to other nodes. I did not add it in this release since there are some issues that need to be worked out and its very messy atm. however since nodes are named. I may allow by default pushing data to another node, but not have the global table to sync since this is where the issue lies.
- Improve Performance
- Fix supporting libraries (Bin, and net need tons of work)
- Look for the bugs
- Figure out what I can do to make this library more awesome
Note On Queues: When it comes to network queues, they only send 1 way. What I mean by that is that if the master sends a message to a node, its own queue will not get populated at all. The reason for this is because syncing between which popped from what network queue would make things really slow and would not perform well at all. This means you have to code a bit differently. Use: master getFreeNode() to get the name of the node under the least amount of load. Then handle the sending of data to each node that way.
Now there is a little trick you can do. If you combine both networkmanager and systemthreading manager, then you could have a proxy queue for all system threads that can pull from that “node”. Now data passing within a lan network, (And wan network if using the node manager, though p2p isn’t working as i would like and you would need to open ports and make things work. Remember you can define an port for your node so you can port forward that if you want), is fast enough, but the waiting problem is something to consider. Ask yourseld what you are coding and if network paralisim is worth using.
Note: These examples assume that you have already connected the nodes to the node manager. Also you do not need to use the node manager, but sometimes broadcast does not work as expected and the master doesnot connect to the nodes. Using the node manager offers nice features like: removing nodes from the master when they have disconnected, and automatically telling the master when nodes have been added. A more complete example showing connections regardless of order will be shown in the example folder check it out. New naming scheme too.

-Updated:- LoadBalancing, well better load balancing than existed before. This one allowed for multiple processes to have their own load reading. Calling this on the multi object will return the total load for the entire multi environment… loads of other processes are indeed affected by what other processes are doing. However, if you combine propriety to the mix of things then you will get differing results… these results however will most likely be higher than normal… different priorities will have different default thresholds of performance.
Fixed:
-- Thread.getName() should now work on lanes and love2d, haven’t tested it much with the luvit side of things…
- A bug with the lovemanager table.remove arguments were backwards
- The queue object in the love2d threading has been fixed! It now supports sending all objects (even functions if no upvalues are present!)
Changed:
-- SystemThreadedJobQueues now have built in load management so they are not constantly at 100% CPU usage.
- SystemThreadedJobQueues pushJob now returns an id of that job which will match the same one that OnJobCompleted returns
Update: 1.9.1
Added:
-- Integration “multi.integration.luvitManager”
- Limited… Only the basic multi:newSystemThread(…) will work
- Not even data passing will work other than arguments… If using the bin library, you can pass tables and function… Even full objects if inner recursion is not present.
Updated:
-- multi:newSystemThread(name,func,…)
- It will not pass the … to the func(). Do not know why this wasn’t done in the first place
- Also multi:getPlatform(will now return “luvit” if using luvit… Though Idk if module creators would use the multi library when inside the luvit environment
Update: 1.9.0
Added:
-- multiobj:ToString() — returns a string representing the object
- multi:newFromString(str) — creates an object from a string
Works on threads and regular objects. Requires the latest bin library to work!

multi:mainloop() -- Start the main loop :D
-That’s it from this version!
Update: 1.8.3
Added:
New Mainloop functions Below you can see the slight differences… Function overhead is not too bad in lua but has a real difference. multi:mainloop() and multi:unprotectedMainloop() use the same algorithm yet the dedicated unprotected one is slightly faster due to having less function overhead.
-- multi:mainloop()* — Bench: 16830003 Steps in 3 second(s)!
- multi:protectedMainloop() — Bench: 16699308 Steps in 3 second(s)!
- multi:unprotectedMainloop() — Bench: 16976627 Steps in 3 second(s)!
- multi:prioritizedMainloop1() — Bench: 15007133 Steps in 3 second(s)!
- multi:prioritizedMainloop2() — Bench: 15526248 Steps in 3 second(s)!
* The OG mainloop function remains the same and old methods to achieve what we have with the new ones still exist
These new methods help by removing function overhead that is caused through the original mainloop function. The one downside is that you no longer have the flexibility to change the processing during runtime.
However there is a work around! You can use processes to run multiobjs as well and use the other methods on them.
I may make a full comparison between each method and which is faster, but for now trust that the dedicated ones with less function overhead are infect faster. Not by much but still faster.
Update: 1.8.2
Added:
-- multi:newsystemThreadedTable(name) NOTE: Metatables are not supported in transfers. However there is a work around obj:init() does this. Look in the multi/integration/shared/shared.lua files to see how I did it!
- Modified the GLOBAL metatable to sync before doing its tests
- multi._VERSION was multi.Version, felt it would be more consistent this way… I left the old way of getting the version just in case someone has used that way. It will eventually be gone. Also multi:getVersion() will do the job just as well and keep your code nice and update related bug free!
- Also everything that is included in the: multi/integration/shared/shared.lua (Which is loaded automatically) works in both lanes and love2d environments!
The threaded table is setup just like the threaded queue.
It provids GLOBAL like features without having to write to GLOBAL!
This is useful for module creators who want to keep their data private, but also use GLOBAL like coding.
It has a few features that makes it a bit better than plain ol GLOBAL (For now…)
(ThreadedTable - TT for short) This was modified by a recent version that removed the need for a sync command
-- TT:waitFor(name)
- TT:sync()
- TT[“var”]=value
- print(TT[“var”])
we also have the “sync” method, this one was made for love2d because we do a syncing trick to get data in a table format. The lanes side has a sync method as well so no worries. Using indexing calls sync once and may grab your variable. This allows you to have the lanes indexing ‘like’ syntax when doing regular indexing in love2d side of the module. As of right now both sides work flawlessly! And this effect is now the GLOBAL as well
On GLOBALS sync is a internal method for keeping the GLOBAL table in order. You can still use sThread.waitFor(name) to wait for variables that may or may not yet exist!
Time for some examples:
Using multi:newSystemThreadedTable(name)
-- lanes Desktop lua! NOTE: this is in lanesintergratetest6.lua in the examples folder

-Update: 1.7.6
Fixed:
Typos like always
Added:
multi:getPlatform() — returns “love2d” if using the love2d platform or returns “lanes” if using lanes for threading
examples files
In Events added method setTask(func)
The old way still works and is more convent to be honest, but I felt a method to do this was needed for completeness.
Updated:
some example files to reflect changes to the core. Changes allow for less typing
loveManager to require the compat if used so you don’t need 2 require line to retrieve the library
Update: 1.7.5
Fixed some typos in the readme… (I am sure there are more there are always more)
Added more features for module support
TODO:
Work on performance of the library… I see 3 places where I can make this thing run quicker
I’ll show case some old versions of the multitasking library eventually so you can see its changes in days past!
Update: 1.7.4
Added: the example folder which will be populated with more examples in the near future!
The loveManager integration that mimics the lanesManager integration almost exactly to keep coding in both environments as close to possible. This is done mostly for library creation support!
An example of the loveManager in action using almost the same code as the lanesintergreationtest2.lua
NOTE: This code has only been tested to work on love2d version 1.10.2 though it should work version 0.9.0

thread is the interface for multithreads as seen in the threading section
GLOBAL a table that can be used throughout each and every thread
sThreads have a few methods
sThread.set(name,val) — you can use the GLOBAL table instead modifies the same table anyway
sThread.get(name) — you can use the GLOBAL table instead modifies the same table anyway
sThread.waitFor(name) — waits until a value exists, if it does it returns it

-Update: 1.5.0
Added:
-- An easy way to manage timeouts
- Small bug fixes
Update: 1.4.1 - First Public release of the library
IMPORTANT:
Every update I make aims to make things simpler more efficient and just better, but a lot of old code, which can be really big, uses a lot of older features. I know the pain of having to rewrite everything. My promise to my library users is that I will always have backwards support for older features! New ways may exist that are quicker and easier, but the old features/methods will be supported.
Note: Version 2.x.x sort of breaks this promise. Sorry about that, but a new major version means changes that had to be made. Not too much has changed though and base code is 100% compatiable. What changed was how you init the library and some files that were removed due to not really being used by what i have seen. The older backwards compat file was for an older version of the library that was changed before the public release had any traction. The goal is still to provide a easy way to multitask in lua. I’ll try my best however to ensure that not much changes and that changes are easy to make if they are introduced.

+Update: 1.5.0
+Added:
+
+- An easy way to manage timeouts
+- Small bug fixes
+
+Update: 1.4.1 (4/10/2017) - First Public release of the library
+Added:
+
+- SystemThreading very infancy
+
+Change:
+
+- small change to the hold method to make it a bit more lightweight
+
+- Using a timer instead of an alarm object!
+
+
+- Limits to hold:
+
+- cannot hold more than 1 object at a time, and doing so could cause a deadlock!
+
+
+
+Note: Wow you looked back this far. Nice, while your at it take a look at the old versions to view the code how it was before my first initial release
+Upcomming:
+
+- Threaded objects wrapped in corutines, so you can hold/sleep without problems!
+
+Update: 1.4.0 (3/20/2017)
+Added:
+
+- multiobj:reallocate(ProcessObj) -- changes the parent process of an object
+- ProcessObj:getController() -- returns the mThread so you can opperate on it like a multiobj
+Example 1
+
+
+require("multimanager") -- require the library
+int1=multi:newProcess() -- create a process
+int1.NAME="int1" -- give it a name for example purposes
+int2=multi:newProcess() -- create another process to reallocate

+- Load detection!
+
+- multi.threshold -- minimum amount of cycles that all mObjs should be allotted before the Manager is considered burdened. Defualt: 256
+- multi.threstimed -- amount of time when counting the number of cycles, Greater gives a more accurate view of the load, but takes more time. Defualt: .001
+- multi:setThreshold(n) -- method used to set multi.threshold
+- multi:setThrestimed(n) -- method used to set multi.threstimed
+- multi:getLoad() -- returns a number between 0 and 100
+
+
+
+Update: 1.2.0 (12.31.2016)
+Added:
+
+- connectionobj.getConnection(name) -- returns a list of an instance (or instances) of a single connect made with connectionobj:connect(func,name) or connectionobj(func,name) if you can orginize data before hand you can route info to certain connections thus saving a lot of cpu time.
+NOTE: Only one name per each connection... you can't have 2 of the same names in a dictonary... the last one will be used
+Changed:
+
+
+
+- Started keeping track of dates
+- obj=multi:newConnection()

+event:setEvent("test()","a == 1")
+event:setEvent("test2()","b == 5")
+function Event_test()
+ print("Event! A=1 which means the alarm rang")
+ a = 0
+end
+function Event_test2()
+ event:Stop()
+end
+-- this might feel somewhat familiar
+step = event:createStep("test",10,true)
+function Step_test(pos)
+ print(pos,self)
+end
+function Step_test_End(tag)
+ step:Remove()
+end
+function event:OnCreate()
