Crash on multiple async reqs

dr3adx commented 1 year ago

Happens when I try to send around 6 requests per second. Using ASYNCHttpReqs library. I'm so frustrated I thought async requests will work. Like everything works fine until it crashes couple of minutes later.

AsyncTCP.cpp line 420 specifically

have you found any solution @dr3adx ? I am facing the same problem.

trycoon commented 1 year ago

@dr3adx @umerm64 AsyncTCP is a wonderful library riddled with bugs, there has been lots of Pull request to fix these, they are never merged, it's just too sad for something as good as this. Do this fork improve your situation? https://github.com/smarthomerocks/AsyncTCP

dr3adx commented 1 year ago

@umerm64 havent found solution, its broken on god knows what level

@trycoon i actually applied all open pull requests, to no avail. This issue happens on low level when trying to obtain IP/socket on ip_tcp level

trycoon commented 1 year ago

@dr3adx I used to have trouble with the ESP32 getting Panics and rebooting when receiving multiple requests, but after applying the pull requests in my fork it is much more stable now. Did you remeber to increase the CONFIG_ASYNC_TCP_QUEUE_SIZE to something bigger than the default 32? I'm running -DCONFIG_ASYNC_TCP_QUEUE_SIZE=512

Hello bro, yes i've tried that, but my issue is when sending multiple requests from multiple AsyncClients. Basically web scraping. I would also get some crash along the lines: tcp_rcv_wnd < 0xFFFF

What crash specifically did you get before?

My case can be easily reproduced by making a system which should send API req to 10 different websites, each holding a unique cookie and to a different URL so its a session. So initializing 10 AsyncClient objects is where the problem happens I think, because with low amount of async reqs, e.g 3 the issue doesnt happen. But then again, even 10 is nothing, 100+ async reqs in a given time can be easily handled in nodejs for comparison

umerm64 commented 1 year ago

@trycoon I am also getting the same error on this one too. :( https://github.com/smarthomerocks/AsyncTCP

Basically the crash is happening when too many concurrent http requests are sent to controller. Is there a way to throttle/queue the requests ?

I'm on it improving, last published should be ok (and far better), but now developing TLS with stabilizing the TCP management.

Hi @HamzaHajeir is your library compatible with ESPAsyncWebServer?

Hi @HamzaHajeir is your library compatible with ESPAsyncWebServer?

Hi @johnnytolengo, it's not, really.

But the stack comes with a stable H4AsyncWebServer that you can check out.

how do I get this running in platformio? do I need h4plugins ? do I need AardvarkTCP?

My current platformio config:

lib_deps = 
    https://github.com/HamzaHajeir/H4
    https://github.com/HamzaHajeir/H4Tools
    https://github.com/HamzaHajeir/H4AsyncTCP@^0.0.18
    https://github.com/HamzaHajeir/ArmadilloHTTP
    khoih-prog/ESPAsync_WiFiManager@>=1.15.1

I'm trying to compile example program and I get error during linking: https://pastebin.com/ZgStVidc

HamzaHajeir commented 11 months ago

Please checkout the platformio environment here: https://github.com/hamzahajeir/h4plugins_env

And it's important to utilize h4 APIs h4setup and h4UserLoop instead of setup and loop.

Got it. i downloaded your platformio project. However, I can only compile env:esp32s3-devkitc otherwise with other envs i get error:

.pio/libdeps/espwroom32/H4AsyncTCP/src/H4AsyncTCP.h:197:21: error: 'ip_addr_t' does not name a type; did you mean

but my board is not esp32s3-devkitc and i cannot upload firmware (even tho it compiles successfully), and it doesnt compile with board i normally use "az-delivery-devkit-v4" If I set -DLWIP_ALTCP=0 to zero I can compile just fine what should I do?

HamzaHajeir commented 11 months ago

If you don't need TLS it's fine, remove LWIP_ALTCP and everything will be fine.

If you do need it, please let me know to check it out at sooner.

Per the ip_addr_t there's apparently a missing header only for esp32 "lwip/ip_addr.h', one can include in H4AsyncTCP.h file.

Per the issue, I've double checked the example, it successfully read the body response:

My question is how stable is the H4AsyncWebServer and if worth to replace the ESPAsyncWebServer?

I personally rely over the H4 stack in my product(s), I can tell you that the environment works as a charm*, including HTTP(s) requests, Webserver (even TLS**), and MQTT over TLS communication, with large payloads. completely async.

The testbed was working up to weeks (until I uploaded another sketch or something else), with no memory leak nor crashes.

* As long as there's available memory (ESP8266 is so limited). ** There's an issue that I've experienced for a TLS webserver, and until now it's open: I'm personally not interested because there's no reason for local webserver over TLS, even the routers don't run TLS webservers, MCUs are not a choice for public webservers.

I will play around and let you know regarding JSON. But how can I disable logs like H=229600 M=110580 m=219940 S=5596 I tried defining H4AT_DEBUG 0 in config.h and it's not working, they're killing my console :/ I want to disable all logs in your example main.cpp

Thanks a lot! Also I further debugged empty JSON response body. I'm banging my head because this is a one liner but its not working. Most websites return proper JSON with your H4 except when I try to GET http://192.168.1.105/app (the Tapo P105 remote switch) on my local network.

However, same request works in Postman and returns proper json body.

{
    "error_code": -1009
}

With your H4 weird thing is that status code returned is correct: 200 and content length is 20 (correct), but both asJsonstring & asStdstring methods return empty string.

My code & output is here: https://pastebin.com/hVtWtzmj Please help bro I really think the problem is in the library somewhere because content length and status code returned are fine.

@HamzaHajeir : I have an app using AsyncTCP, ESPAsyncWebServer and libraries using WebSocket. So I cannot use the H4 stack, but I was wondering if your AsyncTCP fork (https://github.com/HamzaHajeir/H4AsyncTCP) can be directly used as a replacement of the original AsyncTCP instead ? Thanks !

Hi Matheiu, I'm really cannot tell exactly, there should be some similarity in APIs (onData/onRX) - (onConnect) - (onError). Philbowles had a different internal design.

Perhaps this comparison sketch shows some differences in APIs, I think one can try to port the aforementioned libraries to H4AsyncTCP and try out, for TCP stuff it's solid and works great up to my experience and knowledge (spent months to fully support it with fixes, but had to take extreme care dealing with TCP object in upper layers (MQTT/HTTP/Webserver) as it's expirable and nullable pointer that should be nullified on every error / disconnect / connectFail).

I'm really unaware of how ESPAsyncWebServer is designed, and whether there's a critical break in dealing to H4AsyncTCP.

Take a look at H4AsyncTCP documentation regarding dealing with the server.

But perhaps changing to H4AsyncWebServer might be easier, take a look at this comment, beside taking a look on how H4Plugins uses it.

Note: Basic authentication was added, and filesystem serving root is fixed (used within H4Plugins)

HamzaHajeir commented 11 months ago

As dealing with H4AsyncTCP as a client, one might take a look how H4 stack uses it:

MQTT.
HTTP.

the json {"error_code":-1 displays now in the log at least! just have to find out why its not being returned in asJson method.

HamzaHajeir commented 11 months ago

This is because the webserver sends two separate TCP packets, both holding PUSH flag for immediate processing.

Other stream-based clients does "suck" data out of pool, unlike H4AsyncTCP which is completely event-driven.

Can you checkout Wireshark and validate it's only one TCP packet (not as I've described)?

HamzaHajeir commented 11 months ago

Alternatively, you can just turn H4AT_DEBUG 2 under h4async_config.h (Under H4AsyncTCP) and paste the output, it will print the flags by the following line:

    H4AT_PRINT2("_raw_recv %p data=%p L=%d f=0x%02x \n",rq,cpydata,cpylen,cpyflags);

f=0x01 is PBUF_FLAG_PUSH.

The webserver behaviour should be corrected, either to send one TCP packet including body, or to detach PUSH flag from the first TCP packet.

@mathieucar Let me know if you were able to replace the original AsyncTCP with the H4AsyncTCP and how you did it with ESPAsyncWebServer.

Real problem :\, as if they wanted to chunk it out, there's a standardized way to do in HTTP protocol and it's managed within the library*.

The issue is similar to this one except TLS isn't used here, we're out of the standards already.

I've gave it a thought, if to add a workaround to the library, it wont be a library anymore, as it will be custom to solve that case

But what you can do is something will be tough to some extent, is to work with H4AsyncTCP directly, manually write the request, and onRX you manage to combine up the fragments, with a simple trick to find the json by finding its start '{', then copy that to the end of your buffer. You'll need somehow to manage TCP pointer lifetime.

Alternatively you might use a stream-based HTTP client, as what esp32-arduino offers, which seems to me it solves your current problem if you don't really bother whether it's async or not.

* There's a current bug for handling very large responses.

But what you can do is something will be tough to some extent, is to work with H4AsyncTCP directly, manually write the request, and onRX you manage to combine up the fragments, with a simple trick to find the json by finding its start '{', then copy that to the end of your buffer. You'll need somehow to manage TCP pointer lifetime.

Alternatively you might use a stream-based HTTP client, as what esp32-arduino offers, which seems to me it solves your current problem if you don't really bother whether it's async or not.

There's a current bug for handling very large responses.

well its not really a "custom" problem, it works just fine in Postman and other HTTP clients how can i chain multiple async requests with h4? i need to check every IP on the subnet, so 255 requests, ill just use status code since json body isnt working

I tried queueing 255 reqs using h4.queue function but not a single req executes :O

Other HTTP clients are either stream-based, or event-driven. I don't think this is a problem for Stream-based clients to a good extent, but if event driven they might insert the workarounds outside the standards. Some of other clients can do more advanced workarounds to deal with uncompliant servers, as correcting the order of out-of-order HTTP chunks (even worse than that), which happened in my webserver and found the browser just fixes that, before I fixed the bug here ofcourse. If I didn't fix it and you were to request by a moderate client, you will find it very hard to parse, as it will be a bunch of scrambled data to you.

Per the current issue, for any TCP packet which holds PUSH flag, it tells you "I'm finished, please process the message immediately", thus the client receives the pushed message and process it as per the HTTP standard, in your case the sender does just lie :).

I'm not sure what you're aiming for, seems want to discover it? The common way to do is via mDNS, can you check the Tapo P105 documentation for such a feature?

Per requests, at least some does and the other just don't (you'll need to add callbacks onConnectFail/onError/onDisconnect to know why); but primarily because there's a limit of 16 simultaneous active pcbs (protocol control blocks) in ESP32.

can 1 pcb only handle 1 simultaneous request at a time? or what does this mean in terms of performance?

also device im trying to ping doesnt use mDNS service so i have to http request every IP on subnet (for discovery), how would I go about doing this efficiently with H4?

Each one controls only one TCP connection.

Hi. I'm just reading the thread again. Hope you have managed to solve your issue :-)

FYI I am maintaining since a while now (with some help):

AsyncTCP : https://github.com/mathieucarbou/AsyncTCP
ESPAsyncWebServer: https://github.com/mathieucarbou/ESPAsyncWebServer

These forks are used in some big projects out there (OpenDTU, Beelance, YaSolR, ESP-DASH, ElegantOTA, ESPConnect, WebSerial, etc). I have an app doing a LOT of websocket calls without any issue (at a rate of about 3-4 push per sec).

I've merged inside a couple of PRs standing there, plus added Arduino 3 support, ArduinoJson 7, IPv6 (improved from ESPHome draft), etc

You might want to check them out.

https://github.com/HamzaHajeir/H4AsyncTCP is not an option because of its too restrictive license.

Glad to hear you've fixed your issue.

Per the license, the author has passed in June 2022, leaving the work in the middle, then I took the lead to complete his work and make it useful to the world, I tried to get to his family (only one sister) regarding the license, and other people tried to reach her, but with no luck, she seems not so engaged on the internet and we have no other contact method.

Opening the license to the world is an option if we could not reach her, but it's the last resort for me.

BTW I'm running a reliable sketch that publishes 13k of MQTTv5.0 over TLS every 3 seconds, with running HTTPS and WSS, alongwith HTTPs Client that fetches every 15 seconds a TLS HTTP API.
