Line buffering is enabled by using the argument buffering=1 as defined in io.open.

I did not update the docs for socket.makefile since it already mentions the arguments being interpreted the same way as open:

Return a file object associated with the socket. The exact returned type depends on the arguments given to makefile(). These arguments are interpreted the same way as by the built-in open() function, except the only supported mode values are 'r' (default), 'w' and 'b'.

Added a warning in binary mode, as in open(). LGTM now. 👍

@serhiy-storchaka
Follow open() in binary mode and rename the NEWS entry
7e6b6c5 
open() emits a RuntimeWarning for buffering=1 in binary mode and uses the
default buffer size.

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot AMD64 Alpine Linux NoGIL 3.x (tierless) has failed when building commit dbac03b.

What do you need to do:

  1. Don't panic.
  2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/#/builders/1819/builds/2802) and take a look at the build logs.
  4. Check if the failure is related to this commit (dbac03b) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:

https://buildbot.python.org/#/builders/1819/builds/2802

pythongh-75245: Support line buffering in socket.makefile() (pythonGH…
89ef690 
…-12370)

worked in Python 2.  In binary mode it emits a RuntimeWarning and uses the
default buffer size, also as in open().
