* bpo-29136: Add TLS 1.3 cipher suites and OP_NO_TLSv1_3 (#1363)Christian Heimes2017-09-081-0/+13
| | | | | | | | | | | | | | | | * 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-29505: Add fuzz tests for float(str), int(str), unicode(str) (#2878)Devin Jeanpierre2017-09-064-0/+222
| | | | | | | | | | | | | | | | | | | | | | Add basic fuzz tests for a few common builtin functions. This is an easy place to start, and these functions are probably safe. We'll want to add more fuzz tests later. Lets bootstrap using these. While the fuzz tests are included in CPython and compiled / tested on a very basic level inside CPython itself, the actual fuzzing happens as part of oss-fuzz (https://github.com/google/oss-fuzz). The reason to include the tests in CPython is to make sure that they're maintained as part of the CPython project, especially when (as some eventually will) they use internal implementation details in the test. (This will be necessary sometimes because e.g. the fuzz test should never enter Python's interpreter loop, whereas some APIs only expose themselves publicly as Python functions.) This particular set of changes is part of testing Python's builtins, tracked internally at Google by b/37562550. The _xxtestfuzz module that this change adds need not be shipped with binary distributions of Python.

* bpo-17852: Maintain a list of BufferedWriter objects. Flush them on exit. ↵Neil Schemenauer2017-09-053-1/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#1908) * Maintain a list of BufferedWriter objects. Flush them on exit. In Python 3, the buffer and the underlying file object are separate and so the order in which objects are finalized matters. This is unlike Python 2 where the file and buffer were a single object and finalization was done for both at the same time. In Python 3, if the file is finalized and closed before the buffer then the data in the buffer is lost. This change adds a doubly linked list of open file buffers. An atexit hook ensures they are flushed before proceeding with interpreter shutdown. This is addition does not remove the need to properly close files as there are other reasons why buffered data could get lost during finalization. Initial patch by Armin Rigo. * Use weakref.WeakSet instead of WeakKeyDictionary. * Simplify buffered double-linked list types. * In _flush_all_writers(), suppress errors from flush(). * Remove NEWS entry, use blurb.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Change NPN detection: Version breakdown, support disabled (pre-patch/post-patch): - pre-1.0.1: OPENSSL_NPN_NEGOTIATED will not be defined -> False/False - 1.0.1 and 1.0.2: OPENSSL_NPN_NEGOTIATED will not be defined -> False/False - 1.1.0+: OPENSSL_NPN_NEGOTIATED will be defined and OPENSSL_NO_NEXTPROTONEG will be defined -> True/False Version breakdown support enabled (pre-patch/post-patch): - pre-1.0.1: OPENSSL_NPN_NEGOTIATED will not be defined -> False/False - 1.0.1 and 1.0.2: OPENSSL_NPN_NEGOTIATED will be defined and OPENSSL_NO_NEXTPROTONEG will not be defined -> True/True - 1.1.0+: OPENSSL_NPN_NEGOTIATED will be defined and OPENSSL_NO_NEXTPROTONEG will not be defined -> True/True * Refine NPN guard: - If NPN is disabled, but ALPN is available we need our callback - Make clinic's ssl behave the same way This created a working ssl module for me, with NPN disabled and ALPN enabled for OpenSSL 1.1.0f. Concerns to address: The initial commit for NPN support into OpenSSL [1], had the OPENSSL_NPN_* variables defined inside the OPENSSL_NO_NEXTPROTONEG guard. The question is if that ever made it into a release. This would need an ugly hack, something like: #if defined(OPENSSL_NO_NEXTPROTONEG) && \ !defined(OPENSSL_NPN_NEGOTIATED) # define OPENSSL_NPN_UNSUPPORTED 0 # define OPENSSL_NPN_NEGOTIATED 1 # define OPENSSL_NPN_NO_OVERLAP 2 #endif [1] https://github.com/openssl/openssl/commit/68b33cc5c7

* bpo-10746: Fix ctypes PEP 3118 type codes for c_long, c_bool, c_int (#31)Pauli Virtanen2017-08-281-2/+67
| | | | | | | | | | | | | | | Ctypes currently produces wrong pep3118 type codes for several types. E.g. memoryview(ctypes.c_long()).format gives "<l" on 64-bit platforms, but it should be "<q" instead for sizeof(c_long) == 8 The problem is that the '<>' endian specification in the struct syntax also turns on the "standard size" mode, which makes type characters have a platform-independent meaning, which does not match with the codes used internally in ctypes. The struct module format syntax also does not allow specifying native-size non-native-endian items. This commit adds a converter function that maps the internal ctypes codes to appropriate struct module standard-size codes in the pep3118 format strings. The tests are modified to check for this.
