[New-bugs-announce] [issue22252] ssl blocking IO errors

Hristo Venev report at bugs.python.org

New submission from Hristo Venev:

ssl.SSLWantReadError and ssl.SSLWantWriteError should inherit io.BlockingIOError.

Generic code that works with non-blocking sockets will stop working with SSLSockets.

Does anybody have any idea if SSLSocket.read() will need to write to the underlying socket or SSLSocket.write() need to read from it? AFAIK they don't.

Assuming that ssl.SSLWantReadErorr and ssl.SSLWantWriteError perfectly map to io.BlockingIOError (except during handshake).
