[issue8240] ssl.SSLSocket.write may fail on non-blocking sockets

[Cyril]

Cyril <cbay at excellency.fr> added the comment:

Here is a patch that implements SSLSocket.get_mode/set_mode, with the SSL_MODE_ENABLE_PARTIAL_WRITE and SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER constants defined in the ssl module.

The patch contains a test case and documentation. It's made against trunk 44327 and also applies nicely with --fuzz=3 on a 2.6.5.

There are no compatibility issues as no specific mode is set by default. It's up to the application to call SSLSocket.set_mode before use. I've tested my own use case with a set_mode(SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER), it works nicely.
