* bpo-17852: Maintain a list of BufferedWriter objects. Flush them on exit. ↵Neil Schemenauer2017-09-223-1/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#3372) * 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. * Take more care when flushing file buffers from atexit. The previous implementation was not careful enough to avoid causing issues in multi-threaded cases. Check for buf->ok and buf->finalizing before actually doing the flush. Also, increase the refcnt to ensure the object does not disappear.

| | | | | The concrete PyDict_* API is used to interact with PyInterpreterState.modules in a number of places. This isn't compatible with all dict subclasses, nor with other Mapping implementations. This patch switches the concrete API usage to the corresponding abstract API calls. We also add a PyImport_GetModule() function (and some other helpers) to reduce a bunch of code duplication.

* 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.
