Index out of range error

[Tadimsky]

I'm using 0.7.2 and every so often I see the following error being logged:

Exception in thread Thread-4:
Traceback (most recent call last):
File "/usr/lib/python3.4/threading.py", line 920, in _bootstrap_inner

    packet_type = int(get_character(packet_text, 0))

File "/usr/local/lib/python3.4/dist-packages/socketIO_client/symmetries.py", line 29, in get_byte
    return indexbytes(x, index)
IndexError: index out of range

It then is disconnected (but the events for disconnection never fire) and I then have to restart the service.

It looks kinda similar to #129 but not exactly the same.

Any ideas here? Still seeing this issue intermittently...

Hi Tadimsky, did you ever find a solution to this problem??

[Tadimsky]

@robertlevy11 no, unfortunately not. still have this issue... I'm using it to connect between a Raspberry Pi and a server for communication but the connection keeps going down :(

Plus one, same error as your gays.

[Tadimsky]

@l33klin @robertlevy11 do you guys know if there is some other library to use? Looks like this one is no longer active. :(

[Trickfilm400]

I don't konw, i have the same error. I need a connection on the localhost from my server. On the Raspberry Pi it works without problems

[Trickfilm400]

See here: Install the pip package: socketIO-client-nexus For me it worked!

https://github.com/nexus-devs/socketIO-client-2.0.3

[Nixellion]

+1, I have the same problem with this client. After a few hours this error shows up.

[Roledenez]

I am facing the same issue with Centos 6.9, ain't there a solution yet? this works fine with windows, only the error comes when testing with the centos

[Nixellion]

So far I solved it but setting restart time to like 60 minutes, seems to keep the client up 24\7 now

[nicolamarinello]

@Nixellion how did you fix it?

[Nixellion]

@nm3594 As I mention in my previous post, I set it to only listen for 1 hour, then reconnect.

while True:
    RESTART_DELAY = 60  # in minutes
    socketIO.wait(seconds=RESTART_DELAY * 60)  # conversion for minutes

[Roledenez]

@Nixellion the application I use must response less than 1 second. :(

[Nixellion]

@Roledenez Oh no, this code makes the client RESTART and RECONNECT each hour. It listens for an hour, responding instantly for any incoming message, then it restarts itself and listens for another hour. Or whatever time you set. It responds instantly.

I'm also having this issue:

    return indexbytes(x, index)
IndexError: index out of range

I managed to quickly reproduce it by spawning a lot (1000) threads, all connecting to the same server, and for each connection go into a loop and do emit.

[nicolamarinello]

At the end my problem was that I was using AWS. Now with the same library and the same code I don't have any problem using Google Cloud Compute Engine

[jupe]

@nicolamarinello what kind of problem you had with AWS? exactly same than in description? Did you use ALB/ELB? Have you seen any 502 rest failures? We have seen also problems with AWS with ALB but mostly with REST..

[zulufoxtrot]

I have the same problem with socketIO_client_nexus 0.7.6.

It can happen as early as 5 seconds after the connection is open.

The server is a nodeJS server using some implementation of socketIO 2. One thing I did change is putting the server behind a load balancer. I don't recall having this issue with a single instance of the server.
