recv_into() missing second argument

[jasonwashburn]

Any time I try to use the requests library on my Pyportal since upgrading to CircuitPython 7.1.1 I get the following error:

code.py output:
Connecting to AP...
Connected to WBurn-2G 	RSSI: -50
Fetching text from http://wifitest.adafruit.com/testwifi/index.html
Traceback (most recent call last):

Code done running.

I've tried multiple example files that use the library with the same result. The currently loaded version is the code below.

I'm currently running CircuitPython 7.1.1 Stable with the adafruit_requests library from adafruit-circuitpython-requests-7.x-mpy-1.10.5.zip

[FoamyGuy]

I am seeing the same results on PyPortal with 7.1.1 and 7.2.0-alpha.1

[FoamyGuy]

Also confirmed same error with version 1.10.4 of this library.

[FoamyGuy]

Very strange... Same error on PyPortal with 7.1.0 and 7.0.0

@FoamyGuy could #151 explain this issue? They added a recv_into() method in that PR but it only accepts one argument (buffer), while in adafruit_requests we pass two arguments (buf, and size).

[FoamyGuy]

Issue is not present on FunHouse 7.2.0-alpha.1-163-g1cd3faa06. So it does appear to be somewhat limited. That PR in ESP32SPI does look like it could be related.

[FoamyGuy]

Confirmed issue is not present with version 3.5.14 of ESP32SPI library so I think you've narrowed it down correctly to that change.

[FoamyGuy]

Transferred to ESP32SPI. This is where it will need to be fixed I believe.

recv_into() declared here:

Adafruit_CircuitPython_ESP32SPI/adafruit_esp32spi/adafruit_esp32spi_socket.py

Line 164 in 52208e4

def recv_into(self, buffer):

only has one parameter. But the requests library is written to pass in two arguments here:
https://github.com/adafruit/Adafruit_CircuitPython_Requests/blob/main/adafruit_requests.py#L241

I think the recv_into() method here will need to accept a second argument for size.

[tekktrik]

Oops! Didn't realize it needed a second parameter when I implemented it not long ago. Thanks y'all, hot fix PR submitted!

Resolved by #155
