[3.7] bpo-33353: Fix test_asyncio on FreeBSD (GH-7087)
* bpo-33353: test_asyncio uses smaller sendfile data (#7083)
bpo-32622, bpo-33353: sendfile() tests of test_asyncio use socket
buffers of 1 kB "to test on relative small data sets". Send only
160 KiB rather 10 MB to make the test much faster.
Shrink also SendfileBase.DATA from 1600 KiB to 160 KiB.
On Linux, 3 test_sock_sendfile_mix_with_regular_send() runs now take
less than 1 second, instead of 18 seconds.
On FreeBSD, the 3 tests didn't hang, but took 3 minutes. Now
the 3 tests pass in less than 1 seconds.
(cherry picked from commit 2932755cc11fd82b4908d60b24b837aa4f3028e6)
* bpo-33353: test_asyncio set SO_SNDBUF after connect (GH-7086)
bpo-32622, bpo-33353: On macOS, sock.connect() changes the
SO_SNDBUF value. Only set SO_SNDBUF and SO_RCVBUF buffer sizes
once a socket is connected or binded, not before.
(cherry picked from commit b97de3dd86046ac46567146d86a69d4f78ea09db)
