3.7.2 Final


    bpo-31715: Associate .mjs file extension with application/javascript MIME Type.


    bpo-35499: make profile-opt no longer replaces CFLAGS_NODIST with CFLAGS. It now adds profile-guided optimization (PGO) flags to CFLAGS_NODIST: existing CFLAGS_NODIST flags are kept.
    bpo-35257: Avoid leaking the linker flags from Link Time Optimizations (LTO) into distutils when compiling C extensions.


    bpo-35259: Conditionally declare Py_FinalizeEx() (new in 3.6) based on Py_LIMITED_API. Patch by Arthur Neufeld.


Python 3.7.2 release candidate 1

Release date: 2018-12-11

    bpo-34812: The -I command line option (run Python in isolated mode) is now also copied by the multiprocessing and distutils modules when spawning child processes. Previously, only -E and -s options (enabled by -I) were copied.
    bpo-34791: The xml.sax and xml.dom.domreg no longer use environment variables to override parser implementations when sys.flags.ignore_environment is set by -E or -I arguments.

Core and Builtins

    bpo-35444: Fixed error handling in pickling methods when fail to look up builtin “getattr”.
    bpo-35436: Fix various issues with memory allocation error handling. Patch by Zackery Spytz.
    bpo-35357: Internal attributes’ names of unittest.mock._Call and unittest.mock.MagicProxy (name, parent & from_kall) are now prefixed with _mock_ in order to prevent clashes with widely used object attributes. Fixed minor typo in test function name.
    bpo-35372: Fixed the code page decoder for input longer than 2 GiB containing undecodable bytes.
    bpo-35336: Fix PYTHONCOERCECLOCALE=1 environment variable: only coerce the C locale if the LC_CTYPE locale is “C”.
    bpo-33954: For str.format(), float.__format__() and complex.__format__() methods for non-ASCII decimal point when using the “n” formatter.
    bpo-35269: Fix a possible segfault involving a newly-created coroutine. Patch by Zackery Spytz.
    bpo-35214: Fixed an out of bounds memory access when parsing a truncated unicode escape sequence at the end of a string such as '\N'. It would read one byte beyond the end of the memory allocation.
    bpo-35214: The interpreter and extension modules have had annotations added so that they work properly under clang’s Memory Sanitizer. A new configure flag –with-memory-sanitizer has been added to make test builds of this nature easier to perform.
    bpo-35193: Fix an off by one error in the bytecode peephole optimizer where it could read bytes beyond the end of bounds of an array when removing unreachable code. This bug was present in every release of Python 3.6 and 3.7 until now.
    bpo-29341: Clarify in the docstrings of os methods that path-like objects are also accepted as input parameters.

    bpo-34824: Fix a possible null pointer dereference in Modules/_ssl.c. Patch by Zackery Spytz.
    bpo-1621: Do not assume signed integer overflow behavior (C undefined behavior) when performing set hash table resizing.

    bpo-35330: When a Mock instance was used to wrap an object, if side_effect is used in one of the mocks of it methods, don’t call the original implementation and return the result of using the side effect the same way that it is done with return_value.
    bpo-34172: Revert the fix for this issue previously released in 3.7.1 pending further investigation: Fix a reference issue inside multiprocessing.Pool that caused the pool to remain alive if it was deleted without being closed or terminated explicitly.
    bpo-10496: posixpath.expanduser() now returns the input path unchanged if the HOME environment variable is not set and the current user has no home directory (if the current user identifier doesn’t exist in the password database). This change fix the site module if the current user doesn’t exist in the password database (if the user has no home directory).

    bpo-35277: Update ensurepip to install pip 18.1 and setuptools 40.6.2.
    bpo-35226: Recursively check arguments when testing for equality of objects and add note that tracking of parameters used to create ancestors of mocks in mock_calls is not possible.
    bpo-29564: The warnings module now suggests to enable tracemalloc if the source is specified, the tracemalloc module is available, but tracemalloc is not tracing memory allocations.
