File name Uploaded Description Edit Shane.Hansen, 2012-03-14 16:58 script which asserts that dup() was called and the object returned by makefile has a different fileno() than the socket.

The python docs state that for socket.makefile "The file object references a dup()ped version of the socket file descriptor, so the file object and socket object may be closed or garbage-collected independently."

In fact for dup() is never called, and no additional files are opened. Instead an object is returned which uses the original socket and does buffering.

For me, this is the desired behaviour, but just thought I'd mention the docs were off.

Shane, there are major differences between the makefile docs versions 2 and 3, so could you prepare a patch for this addressed at version 2 only?

New changeset 6e2a72e05b4f by Georg Brandl in branch '2.7':
Closes #14303: socket.makefile() does not call dup() anymore on the socket fd.
