* bpo-31671: re: Convert RegexFlag to int before compile (GH-3862)INADA Naoki2017-10-051-0/+2
| | | | | | sre_compile does bit test (e.g. `flags & SRE_FLAG_IGNORECASE`) in loop. `IntFlag.__and__` and `IntFlag.__new__` made it slower. So this commit convert it to normal int before passing flags to `sre_compile()`.

| | | | | | | | | | * bpo-31499, xml.etree: Fix xmlparser_gc_clear() crash xml.etree: xmlparser_gc_clear() now sets self.parser to NULL to prevent a crash in xmlparser_dealloc() if xmlparser_gc_clear() was called previously by the garbage collector, because the parser was part of a reference cycle.

* bpo-31386: Custom wrap_bio and wrap_socket type (#3426)Christian Heimes2017-09-151-0/+2
| | | | | | | | | SSLSocket.wrap_bio() and SSLSocket.wrap_socket() hard-code SSLObject and SSLSocket as return types. In the light of future deprecation of ssl.wrap_socket() module function and direct instantiation of SSLSocket, it is desirable to make the return type of SSLSocket.wrap_bio() and SSLSocket.wrap_socket() customizable.

* bpo-31455: Fix an assertion failure in ElementTree.XMLParser(). (#3545)scoder2017-09-141-0/+2
| | | | | | * Avoid calling "PyObject_GetAttrString()" (and potentially executing user code) with a live exception set. * Ignore only AttributeError on attribute lookups in ElementTree.XMLParser() and propagate all other exceptions.
* bpo-28556: typing.get_type_hints: better globalns for classes and modules ↵Łukasz Langa2017-09-141-0/+2
| | | | | | | | | | | | | | | (#3582) This makes the default behavior (without specifying `globalns` manually) more predictable for users, finds the right globalns automatically. Implementation for classes assumes has a `__module__` attribute and that module is present in `sys.modules`. It does this recursively for all bases in the MRO. For modules, the implementation just uses their `__dict__` directly. This is backwards compatible, will just raise fewer exceptions in naive user code. Originally implemented and reviewed at https://github.com/python/typing/pull/470.
* bpo-31457: Allow for nested LoggerAdapter objects (#3551)Łukasz Langa2017-09-141-0/+1
| | | | | | Some of the proxied methods use internal Logger state which isn't proxied, causing failures if an adapter is applied to another adapter. This commit fixes the issue, adds a new test for the use case.

* bpo-31233: socketserver.ThreadingMixIn.server_close() (#3523)Victor Stinner2017-09-131-0/+2
| | | | | | | | | socketserver.ThreadingMixIn now keeps a list of non-daemonic threads to wait until all these threads complete in server_close(). Reenable test_logging skipped tests. Fix SocketHandlerTest.tearDown(): close the socket handler before stopping the server, so the server can join threads.
* bpo-28638: Optimize namedtuple() creation time by minimizing use of exec() ↵Raymond Hettinger2017-09-101-0/+9

* bpo-28182: Expose OpenSSL verification results (#3412)Christian Heimes2017-09-081-0/+3

* bpo-29136: Add TLS 1.3 cipher suites and OP_NO_TLSv1_3 (#1363)Christian Heimes2017-09-081-0/+1
| | | | | | | | | | | | | | | | * bpo-29136: Add TLS 1.3 support TLS 1.3 introduces a new, distinct set of cipher suites. The TLS 1.3 cipher suites don't overlap with cipher suites from TLS 1.2 and earlier. Since Python sets its own set of permitted ciphers, TLS 1.3 handshake will fail as soon as OpenSSL 1.1.1 is released. Let's enable the common AES-GCM and ChaCha20 suites. Additionally the flag OP_NO_TLSv1_3 is added. It defaults to 0 (no op) with OpenSSL prior to 1.1.1. This allows applications to opt-out from TLS 1.3 now.

| | | | | | | | | | | | | | * bpo-27340: Use memoryview in SSLSocket.sendall() SSLSocket.sendall() now uses memoryview to create slices of data. This fix support for all bytes-like object.
