lune HTTP server dies when given rapid requests

I haven't looked into Lune's source code much at all so I don't have an inkling of what the underlying issue is, but if lots of requests are sent in succession, the request handler stops responding for whatever reason. This issue seems to be similar to https://github.com/lune-org/lune/issues/104 though that was fixed recently.

Given this simple script,

local net = require "@lune/net"
local task = require "@lune/task"

local handle = net.serve(13337, function(request)
    print(request.body)
    return {
        status = 200,
        body = "roger that\n"
    }
end)

sending a couple of curl requests in rapid succession causes it to silently fail.

https://github.com/lune-org/lune/assets/83253309/f264a69f-fb0c-4e29-9566-cedeed3d7834

This does not happen if the requests are sufficiently spaced apart.

Additionally, this behavior does not seem to occur if you prevent the main thread from ending with say an endless while loop; appending the following code will make it behave as expected.

while true do
    task.wait(1)
end

https://github.com/lune-org/lune/assets/83253309/fab2f940-4116-4e5f-8bf8-3db38ed00036

Currently running this on Linux in case that's relevant, version 0.8.2. I have not tried testing this on Windows yet.

Additionally, this behavior does not seem to occur if you prevent the main thread from ending with say an endless while loop; appending the following code will make it behave as expected.

This makes me think its related to the serve handle getting garbage collected, same as in issue #104 that you mentioned ... Will need some further investigation and/or a more consistent repro, definitely more spooky this time around.

after using this code from the wiki and refreshing just a few times, the server seems to die

local net = require("@lune/net")
 
local counter = 0
net.serve(8080, function()
	counter += 1
	return {

		body = "Hello! This is response #" .. tostring(counter),

@RuizuKun-Dev for now you can use the workaround mentioned in the original post:

while true do
    task.wait(1)

I think I have a good idea of how this could be fixed but it will have to wait for #188 to be merged

Editing to note the first example code I wrote appears to be stable. Have built an entire backend and absolutely spammed it with requests without a single issue so far.

While building a ExpressJS-like framework on the latest release of Lune, I noticed as long as you initialize the local variable first, then assign the handler to it later, the ServeHandle operates as expected:

local ServerHandler
local ModuleRoot = {}
function ModuleRoot.StartServer()
  assert(typeof(ServerHandler) == "nil", "HttpServer is already running!")

  ServerHandler = net.serve(
    8080,
    function(Request) 
      return {status = 200, body = "hi"} 
    end
  )
end

ModuleRoot.StartServer() -- works as expected!

However, if you attempt to immediately initialize the local variable, the garbage collection issue occurs:

local ModuleRoot = {}
function ModuleRoot.StartServer()
  return net.serve(
    8080,
    function(Request) 
      return {status = 200, body = "hi"} 
    end
  )
end

local ServerHandler = ModuleRoot.StartServer() -- gives up after about 6 ~ 12 requests

~~This indicates the issue has to do with immediate initialization of the variable compared to an already initialized one.~~

EDIT: On second thought, variable initialization is unlikely to be the issue since the while true do loop also keeps the server alive. I unfortunately don't know much outside of Lua, but I do suspect this has something to do with how the Lua scope is handled on the Rust side.

work around you mentioned didn't work I noticed it broke when output is "Hello! This is response #13"

also why does it increment counter by 2 each time i refresh?

Use the workaround I listed right above your comment. I've thoroughly tested it and haven't had any garbage collection issues since. No while true do loop required.

I was testing some http benchmarking on lune's net package and ran into this. While saving the net.serve result to a global variable helps somewhat, it doesn't fix the issue entirely. With the global variable, I can run wrk with one concurrent request (-c1), but as soon as I bump it up to two concurrent requests, the web server silently crashes like before. Would be curious what's causing this.

To clarify, did you mean a local variable? If you actually used a global variable, I haven't tested my workaround against it and thus cannot validate it. As for the local variable method, I'll try to hammer it some more but it's been working perfectly for me.

Jun 19 '24 08:06 Reinitialized

@Reinitialized Yes! I meant local top level scope, apologies. It works fine when you don't have more than one concurrent connection. Try giving the wrk benchmarking tool a try with higher concurrent requests values. https://github.com/wg/wrk

Just gave this a test using wrk and some tests in Studio, and it handled each and every request in order without a problem. I double-checked my implementation and the example I provided and its basically the same, but just in case here is the exact implementation I'm using for this.

Using your implementation results in the same crash for me. I'm on a MacBook Pro M2 Max machine FWIW.

Even with only 5 concurrent requests it crashes in about a second:

That is so odd. The only two differences I can think of is I'm using AlmaLinux 9 on x86, and you macOS on ARM. In the shell, can you set the environment variable RUST_LOG=trace and see if it catches anything? I tried it on my end, but it doesn't crash :/

Jun 22 '24 22:06 Reinitialized

Arighty, after getting wrk compiled and running the exact same test you did, I do see Requests seem to stop after about 64~128 total requests:

Interestingly however, it seems to stop ALL threads, as I had a loop printing the ServeHandler variable to see if it went nil or anything like that. This is making me think this issue is related to #195

I've also run into the issue myself using Lune 0.8.6. I've tried all the workarounds mentioned above, but none seemed to work. What I have also noticed is that the CPU usage of the lune program gets higher when this occurs? I don't know if it's relevant in any way but I decided I might as well share this info.

Here's my code:


local net = require("@lune/net")
local error_response = require("./error_response.luau")

local ServerHandler

local ModuleRoot = {}

function ModuleRoot.StartServer()
    assert(typeof(ServerHandler) == "nil", "HttpServer is already running!")

    ServerHandler = net.serve(8080, function(request: net.ServeRequest) : net.ServeResponse
        print(request.path)
        print(request.headers)
        print(request.body)
        if request.path == "/" then
            if request.method and request.method == "GET" then
                return {
                    status = 200,
                    body = "roger that\n"
                }
            else
                return error_response("BadRequest")
            end
        else
            return error_response("NotFound")
        end
    end)
end

ModuleRoot.StartServer()

and here's a video I recorded:

https://github.com/user-attachments/assets/d1f77133-6cd3-46f9-b262-36c49801be2d

At some point it just stops reacting to the requests

I've also run into the issue myself using Lune 0.8.6. I've tried all the workarounds mentioned above, but none seemed to work. What I have also noticed is that the CPU usage of the lune program gets higher when this occurs? I don't know if it's relevant in any way but I decided I might as well share this info.

Here's my code:


local net = require("@lune/net")
local error_response = require("./error_response.luau")

local ServerHandler

local ModuleRoot = {}

function ModuleRoot.StartServer()
    assert(typeof(ServerHandler) == "nil", "HttpServer is already running!")

    ServerHandler = net.serve(8080, function(request: net.ServeRequest) : net.ServeResponse
        print(request.path)
        print(request.headers)
        print(request.body)
        if request.path == "/" then
            if request.method and request.method == "GET" then
                return {
                    status = 200,
                    body = "roger that\n"
                }
            else
                return error_response("BadRequest")
            end
        else
            return error_response("NotFound")
        end
    end)
end

ModuleRoot.StartServer()

and here's a video I recorded:

At some point it just stops reacting to the requests

and the log:

Perfect! The detailed tracing information was what I was attempting to get, but I must have done it wrong...

Again, I'm not 100% certain since I'm not familar with Rust, but based on how the logs end, this makes me further suspect relations with #195

Here is my work around.

Keeps the process alive.
Prevents GC of the server.

local net = require("@lune/net")
local task = require("@lune/task")

local server = net.serve(8080, function(request)
	return {
		status = 200,
		body = "Echo:\n",
	}
end)

print("Server running on http://localhost:8080")

while true do
	local a = server;
