This is an automated heads-up that we've just merged a Pull Request
that removes the STATIC macro from MicroPython's C API.

See #13763

A search suggests this PR might apply the STATIC macro to some C code. If it
does, then next time you rebase the PR (or merge from master) then you should
please replace all the STATIC keywords with static.

Although this is an automated message, feel free to @-reply to me directly if
you have any questions about this.

Apart from the STATIC changes, this went rather stale all recent mbedtls changes as well, and the switch from Appveyor to Github Actions; I updated everything now. The 2 mingw standard variant builds currently fail, but there's something weird going on with how Github Actions runs these builds and I'm still looking into that.

Fix in #14188

So, during the EuroPython 2026 @jonnor has organized a sprint on MicroPython.
I had a look into this stale PR.

I have forked micropython and rebased the branch of @stinos onto a fresh master and it is ready to be picked up by whoever wants to push this further:
https://github.com/systematicguy/micropython/tree/winsock

There were some conflicts, all of them straightforward.

It works, has been tested using the standard PyVariant using this file:

# https_test.py
import socket
import ssl

host = "api.open-meteo.com"
addr = socket.getaddrinfo(host, 443)[0][-1]

sock = socket.socket()
try:
    sock.connect(addr)

    sock = ssl.wrap_socket(sock, server_hostname=host)
    sock.write(
        b"GET /v1/forecast?latitude=59.91&longitude=10.75&current=temperature_2m HTTP/1.0\r\nHost: %s\r\n\r\n" % host.encode()
    )
    print(sock.read(600))
finally:
    sock.close()

Steps to build and test on windows:

cd micropython\ports\windows
msbuild "..\..\mpy-cross\mpy-cross.vcxproj" /p:Configuration=Release /p:Platform=x64 /p:PyVariant=standard
msbuild micropython.vcxproj /t:UpdateSubmodules
msbuild micropython.vcxproj /p:Configuration=Release /p:Platform=x64
# minimal smoketest:
.\build-standard\Releasex64\micropython.exe -c "import socket, ssl; print('socket+ssl OK')"
# actual test:
.\build-standard\Releasex64\micropython.exe https_test.py
