Antoine Pitrou <[email protected]> added the comment:
The intuitive explanation seems to be:
- there are some bytes available for reading on the *TCP socket*, therefore
asyncore calls the read handler
- however, there are not enough bytes for OpenSSL to actually decrypt any data,
which is why we get SSL_ERROR_WANT_READ when trying to read from the *SSL
socket*
The following patch seems to fix test_ftplib; any thoughts?
