Thanks for the report. We definitely have to fix `AttributeError`. Unfortunately, SSL implementation in asyncio is very tricky. Yuri has an experimental asyncio ssl replacement in his uvloop project rewritten from scratch. There is a plan to port it into asyncio itself. P.S. `await writer.drain()` doesn't send all data to buffer but ensures that the write buffer size is below high watermark limit (https://docs.python.org/3/library/asyncio-protocol.html#asyncio.WriteTransport.set_write_buffer_limits) Actually, it is good. Even after pushing a data into socket buffer you have no knowledge when the data is delivered to peer (or maybe not delivered at all at the moment of socket closing). Moreover, when I experimented with write buffer disabling (transport.set_write_buffer_limits(1)) in aiohttp server benchmarks was executed about 50% slower for simple 'ping' request. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36098> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
