* asyncio: __del__() keep reference to warnings.warn (GH-11491)Victor Stinner2019-01-101-3/+2
| | | | | | | | | | | | | | | * asyncio: __del__() keep reference to warnings.warn The __del__() methods of asyncio classes now keep a strong reference to the warnings.warn() to be able to display the ResourceWarning warning in more cases. Ensure that the function remains available if instances are destroyed late during Python shutdown (while module symbols are cleared). * Rename warn parameter to _warn "_warn" name is a hint that it's not the regular warnings.warn() function.
* bpo-33694: Fix typo in helper function name (GH-7522)Victor Stinner2018-06-081-1/+1
| | | | | | _feed_data_to_bufferred_proto() renamed to _feed_data_to_buffered_proto() ("bufferred" => "buffered"). Typo spotted by Nathaniel J. Smith.
* bpo-33694: Fix race condition in asyncio proactor (GH-7498)Victor Stinner2018-06-071-20/+1
| | | | | | | | | | | | | | | | The cancellation of an overlapped WSARecv() has a race condition which causes data loss because of the current implementation of proactor in asyncio. No longer cancel overlapped WSARecv() in _ProactorReadPipeTransport to work around the race condition. Remove the optimized recv_into() implementation to get simple implementation of pause_reading() using the single _pending_data attribute. Move _feed_data_to_bufferred_proto() to protocols.py. Remove set_protocol() method which became useless.
* bpo-33769: start_tls: Fix error message; cancel callbacks on error (GH-7403)Yury Selivanov2018-06-051-0/+1
| | | In addition to that, mark SSLTransport as "closed" in its "abort()" method to prevent bogus warnings.
* bpo-33734: asyncio/ssl: a bunch of bugfixes (#7321)Yury Selivanov2018-06-041-32/+29
| | | | | | | * Fix AttributeError (not all SSL exceptions have 'errno' attribute) * Increase default handshake timeout from 10 to 60 seconds * Make sure start_tls can be cancelled correctly * Make sure any error in SSLProtocol gets propagated (instead of just being logged)
* bpo-33654: Support protocol type switching in SSLTransport.set_protocol() ↵Yury Selivanov2018-05-291-4/+7

* bpo-33674: asyncio: Fix SSLProtocol race (GH-7175)Victor Stinner2018-05-281-1/+1
| | | | | | Fix a race condition in SSLProtocol.connection_made() of asyncio.sslproto: start immediately the handshake instead of using call_soon(). Previously, data_received() could be called before the handshake started, causing the handshake to hang or fail.
* bpo-33654: Support BufferedProtocol in set_protocol() and start_tls() (GH-7130)Yury Selivanov2018-05-281-1/+31
| | | | | | | | | | | In this commit: * Support BufferedProtocol in set_protocol() and start_tls() * Fix proactor to cancel readers reliably * Update tests to be compatible with OpenSSL 1.1.1 * Clarify BufferedProtocol docs * Bump TLS tests timeouts to 60 seconds; eliminate possible race from start_serving * Rewrite test_start_tls_server_1

* bpo-31399: Let OpenSSL verify hostname and IP address (#3462)Christian Heimes2018-01-271-6/+0
| | | | | | | | | | | | | | | bpo-31399: Let OpenSSL verify hostname and IP The ssl module now uses OpenSSL's X509_VERIFY_PARAM_set1_host() and X509_VERIFY_PARAM_set1_ip() API to verify hostname and IP addresses. * Remove match_hostname calls * Check for libssl with set1_host, libssl must provide X509_VERIFY_PARAM_set1_host() * Add documentation for OpenSSL 1.0.2 requirement * Don't support OpenSSL special mode with a leading dot, e.g. ".example.org" matches "www.example.org". It's not standard conform. * Add hostname_checks_common_name Signed-off-by: Christian Heimes <christian@python.org>
* bpo-29970: Make ssh_handshake_timeout None by default (#4939)Andrew Svetlov2017-12-201-1/+8

* Issue #22560: New SSL implementation based on ssl.MemoryBIOVictor Stinner2015-01-131-0/+640
The new SSL implementation is based on the new ssl.MemoryBIO which is only available on Python 3.5. On Python 3.4 and older, the legacy SSL implementation (using SSL_write, SSL_read, etc.) is used. The proactor event loop only supports the new implementation. The new asyncio.sslproto module adds _SSLPipe, SSLProtocol and _SSLProtocolTransport classes. _SSLPipe allows to "wrap" or "unwrap" a socket (switch between cleartext and SSL/TLS). Patch written by Antoine Pitrou. sslproto.py is based on gruvi/ssl.py of the gruvi project written by Geert Jansen. This change adds SSL support to ProactorEventLoop on Python 3.5 and newer! It becomes also possible to implement STARTTTLS: switch a cleartext socket to SSL.
