Fixes regression in 3.6.3rc1. Build ----- - bpo-31662: Fix typos in Windows ``uploadrelease.bat`` script. Fix Windows Doc build issues in ``Doc/make.bat``. - bpo-31423: Fix building the PDF documentation with newer versions of Sphinx. What's New in Python 3.6.3 release candidate 1? =============================================== *Release date: 2017-09-18* Security -------- - bpo-29781: SSLObject.version() now correctly returns None when handshake over BIO has not been performed yet. - bpo-30947: Upgrade libexpat embedded copy from version 2.2.1 to 2.2.3 to get security fixes. Core and Builtins ----------------- - bpo-31471: Fix an assertion failure in `subprocess.Popen()` on Windows, in case the env argument has a bad keys() method. Patch by Oren Milman. - bpo-31418: Fix an assertion failure in `PyErr_WriteUnraisable()` in case of an exception with a bad ``__module__`` attribute. Patch by Oren Milman. - bpo-31416: Fix assertion failures in case of a bad warnings.filters or warnings.defaultaction. Patch by Oren Milman. - bpo-31411: Raise a TypeError instead of SystemError in case warnings.onceregistry is not a dictionary. Patch by Oren Milman. - bpo-31373: Fix several possible instances of undefined behavior due to floating-point demotions. - bpo-30465: Location information (``lineno`` and ``col_offset``) in f-strings is now (mostly) correct. This fixes tools like flake8 from showing warnings on the wrong line (typically the first line of the file). - bpo-31343: Include sys/sysmacros.h for major(), minor(), and makedev(). GNU C libray plans to remove the functions from sys/types.h. - bpo-31291: Fix an assertion failure in `zipimport.zipimporter.get_data` on Windows, when the return value of ``pathname.replace('/','\\')`` isn't a string. Patch by Oren Milman. - bpo-31271: Fix an assertion failure in the write() method of `io.TextIOWrapper`, when the encoder doesn't return a bytes object. Patch by Oren Milman. - bpo-31243: Fix a crash in some methods of `io.TextIOWrapper`, when the decoder's state is invalid. Patch by Oren Milman. - bpo-30721: ``print`` now shows correct usage hint for using Python 2 redirection syntax. Patch by Sanyam Khurana. - bpo-31070: Fix a race condition in importlib _get_module_lock(). - bpo-31095: Fix potential crash during GC caused by ``tp_dealloc`` which doesn't call ``PyObject_GC_UnTrack()``. - bpo-31071: Avoid masking original TypeError in call with * unpacking when other arguments are passed. - bpo-30978: str.format_map() now passes key lookup exceptions through. Previously any exception was replaced with a KeyError exception. - bpo-30808: Use _Py_atomic API for concurrency-sensitive signal state. - bpo-30876: Relative import from unloaded package now reimports the package instead of failing with SystemError. Relative import from non-package now fails with ImportError rather than SystemError. - bpo-30703: Improve signal delivery. Avoid using Py_AddPendingCall from signal handler, to avoid calling signal- unsafe functions. The tests I'm adding here fail without the rest of the patch, on Linux and OS X. This means our signal delivery logic had defects (some signals could be lost). - bpo-30765: Avoid blocking in pthread_mutex_lock() when PyThread_acquire_lock() is asked not to block. - bpo-31161: Make sure the 'Missing parentheses' syntax error message is only applied to SyntaxError, not to subclasses. Patch by Martijn Pieters. - bpo-30814: Fixed a race condition when import a submodule from a package. - bpo-30597: ``print`` now shows expected input in custom error message when used as a Python 2 statement. Patch by Sanyam Khurana. Library ------- - bpo-31499: xml.etree: Fix a crash when a parser is part of a reference cycle. - bpo-28556: typing.get_type_hints now finds the right globalns for classes and modules by default (when no ``globalns`` was specified by the caller). - bpo-28556: Speed improvements to the ``typing`` module. Original PRs by Ivan Levkivskyi and Mitar. - bpo-31544: The C accelerator module of ElementTree ignored exceptions raised when looking up TreeBuilder target methods in XMLParser(). - bpo-31234: socket.create_connection() now fixes manually a reference cycle: clear the variable storing the last exception on success. - bpo-31457: LoggerAdapter objects can now be nested. - bpo-31400: Improves SSL error handling to avoid losing error numbers. - bpo-28958: ssl.SSLContext() now uses OpenSSL error information when a context cannot be instantiated. - bpo-27340: SSLSocket.sendall() now uses memoryview to create slices of data. This fixes support for all bytes-like object. It is also more efficient and avoids costly copies. - bpo-31178: Fix string concatenation bug in rare error path in the subprocess module - bpo-31350: Micro-optimize :func:`asyncio._get_running_loop` to become up to 10% faster. - bpo-31170: expat: Update libexpat from 2.2.3 to 2.2.4. Fix copying of partial characters for UTF-8 input (libexpat bug 115): https://github.com/libexpat/libexpat/issues/115 - bpo-29136: Add TLS 1.3 cipher suites and OP_NO_TLSv1_3. - bpo-29212: Fix concurrent.futures.thread.ThreadPoolExecutor threads to have a non repr() based thread name by default when no thread_name_prefix is supplied. They will now identify themselves as "ThreadPoolExecutor- y_n". - bpo-9146: Fix a segmentation fault in _hashopenssl when standard hash functions such as md5 are not available in the linked OpenSSL library. As in some special FIPS-140 build environments. - bpo-27144: The ``map()`` and ``as_completed()`` iterators in ``concurrent.futures`` now avoid keeping a reference to yielded objects. - bpo-10746: Fix ctypes producing wrong PEP 3118 type codes for integer types. - bpo-22536: The subprocess module now sets the filename when FileNotFoundError is raised on POSIX systems due to the executable or cwd not being found. - bpo-31249: concurrent.futures: WorkItem.run() used by ThreadPoolExecutor now breaks a reference cycle between an exception object and the WorkItem object. - bpo-31247: xmlrpc.server now explicitly breaks reference cycles when using sys.exc_info() in code handling exceptions. - bpo-30102: The ssl and hashlib modules now call OPENSSL_add_all_algorithms_noconf() on OpenSSL < 1.1.0. The function detects CPU features and enables optimizations on some CPU architectures such as POWER8. Patch is based on research from Gustavo Serra Scalet. - bpo-31185: Fixed miscellaneous errors in asyncio speedup module. - bpo-31135: ttk: fix the destroy() method of LabeledScale and OptionMenu classes. Call the parent destroy() method even if the used attribute doesn't exist. The LabeledScale.destroy() method now also explicitly clears label and scale attributes to help the garbage collector to destroy all widgets. - bpo-31107: Fix `copyreg._slotnames()` mangled attribute calculation for classes whose name begins with an underscore. Patch by Shane Harvey. - bpo-31061: Fixed a crash when using asyncio and threads. - bpo-30502: Fix handling of long oids in ssl.
