ESP32-S2 "Out of sockets" in 6.2.0-beta.0

[anecdata]

Context manager exit seems to be in place for socket, but:

import time
import wifi
import socketpool

from secrets import secrets

pool = socketpool.SocketPool(wifi.radio)

print("Connect...")
wifi.radio.connect(secrets["ssid"], secrets["password"])
print("RSSI", wifi.radio.ap_info.rssi)

count = 0
packet = bytearray(1)
while True:
    count += 1
    print(count, end=" ")
    packet[0] = 0xFF
    with pool.socket(pool.AF_INET, pool.SOCK_DGRAM) as sock:
        print("Send...")
        sock.sendto(packet, ("192.168.4.32", 16384))
    time.sleep(1)

results in:

Adafruit CircuitPython 6.2.0-beta.0 on 2021-01-22; FeatherS2 with ESP32S2

CPython version continues past where my patience wears out:

import time
import socket

pool = socket

count = 0
packet = bytearray(1)
while True:
    count += 1
    print(count, end=" ")
    packet[0] = 0xFF
    with pool.socket(pool.AF_INET, pool.SOCK_DGRAM) as sock:
        print("Send...")
        sock.sendto(packet, ("192.168.4.32", 16384))
    time.sleep(1)

6.1.0-rc.1 seems to behave fine.

Probably unrelated to the other issue, other than the general problem of "Hierophect is bad at sockets", ha ha. There's supposed to be a subsystem that tracks what sockets have been initialized and makes sure they shut down on reset or close, but that doesn't seem to be working here. I'll give it another spin with your code and see if I can pin it down.

[tannewt]

@hierophect I don't think it's your problem. I probably never made exit call close. (It should automatically.)

[hierophect]

@tannewt no, it's my bad, I forgot to make Close de-register handles from the tracking array, only reset_sockets was doing it. I can fold the change into the SSLSocket PR.

I'm still getting this issue with magtag.network.fetch on 6.2.0-beta.2.

[anecdata]

@KTibow What version of adafruit_requests do you have? There were a couple of socket leaks plugged recently. Can you try the latest if you're not already using it?

I posted a question in the forum and they directed me here:
I just updated my UF2 file to 6.2.0 Beta 2 and tried the Internet Test from the Learn Guide
https://learn.adafruit.com/adafruit-metro-esp32-s2/circuitpython-internet-test
I get the out of sockets error running the Internet test:
Fetching and parsing json from https://api.github.com/repos/adafruit/circuitpython Traceback (most recent call last): File "code.py", line 55, in <module> File "adafruit_requests.py", line 598, in get File "adafruit_requests.py", line 559, in request File "adafruit_requests.py", line 436, in _get_socket File "adafruit_requests.py", line 433, in _get_socket RuntimeError: Out of sockets
The Error occurs on the second time the code runs. BTW I also updated the Libraries today as well.

Never mind. I got pointed the the latest version that has not been release yet, but is in the pipeline. It worked._
