+Object allocators
+=================
+
+The following function sets, modeled after the ANSI C standard, but specifying
+behavior when requesting zero bytes, are available for allocating and releasing
+memory from the Python heap.
+
+By default, these functions use :ref:`pymalloc memory allocator <pymalloc>`.
+
+.. warning::
+
+ The :term:`GIL <global interpreter lock>` must be held when using these
+ functions.
+
+.. c:function:: void* PyObject_Malloc(size_t n)
+
+ Allocates *n* bytes and returns a pointer of type :c:type:`void\*` to the
+ allocated memory, or *NULL* if the request fails.
+
+ Requesting zero bytes returns a distinct non-*NULL* pointer if possible, as
+ if ``PyObject_Malloc(1)`` had been called instead. The memory will not have
+ been initialized in any way.
+
+
+.. c:function:: void* PyObject_Realloc(void *p, size_t n)
+
+ Resizes the memory block pointed to by *p* to *n* bytes. The contents will be
+ unchanged to the minimum of the old and the new sizes.
+
+ If *p* is *NULL*, the call is equivalent to ``PyObject_Malloc(n)``; else if *n*
+ is equal to zero, the memory block is resized but is not freed, and the
+ returned pointer is non-*NULL*.
+
+ Unless *p* is *NULL*, it must have been returned by a previous call to
+ :c:func:`PyObject_Malloc`, :c:func:`PyObject_Realloc` or :c:func:`PyObject_Calloc`.
+
+ If the request fails, :c:func:`PyObject_Realloc` returns *NULL* and *p* remains
+ a valid pointer to the previous memory area.
+
+
+.. c:function:: void PyObject_Free(void *p)
+
+ Frees the memory block pointed to by *p*, which must have been returned by a
+ previous call to :c:func:`PyObject_Malloc`, :c:func:`PyObject_Realloc` or
+ :c:func:`PyObject_Calloc`. Otherwise, or if ``PyObject_Free(p)`` has been called
+ before, undefined behavior occurs.
+
+ If *p* is *NULL*, no operation is performed.
+
+
+In addition, the following macro sets are provided:
+
+* :c:func:`PyObject_MALLOC`: alias to :c:func:`PyObject_Malloc`
+* :c:func:`PyObject_REALLOC`: alias to :c:func:`PyObject_Realloc`
+* :c:func:`PyObject_FREE`: alias to :c:func:`PyObject_Free`
+* :c:func:`PyObject_Del`: alias to :c:func:`PyObject_Free`
+* :c:func:`PyObject_DEL`: alias to :c:func:`PyObject_FREE` (so finally an alias
+ to :c:func:`PyObject_Free`)
+
+
+.. _pymalloc:
+
+The pymalloc allocator
+======================
+
+Python has a *pymalloc* allocator optimized for small objects (smaller or equal
+to 512 bytes) with a short lifetime. It uses memory mappings called "arenas"
+with a fixed size of 256 KiB. It falls back to :c:func:`malloc` and
+:c:func:`realloc` for allocations larger than 512 bytes.
+
+*pymalloc* is the default allocator of :c:func:`PyObject_Malloc`.
+
+The arena allocator uses the following functions:
+
+* :c:func:`mmap` and :c:func:`munmap` if available,
+* :c:func:`malloc` and :c:func:`free` otherwise.
+
+.. versionchanged:: 2.7.7
+ The threshold changed from 256 to 512 bytes. The arena allocator now
+ uses :c:func:`mmap` if available.
+
+
.. _memoryexamples:

- self->ob_type->tp_free((PyObject*)self);

-
Notice the use of a temporary variable in :c:func:`Noddy_clear`. We use the
temporary variable so that we can set each member to *NULL* before decrementing
its reference count. We do this because, as was discussed earlier, if the

+we need to untrack the object from GC by calling :c:func:`PyObject_GC_UnTrack`

Can Python be compiled to machine code, C or some other language?
-----------------------------------------------------------------
-Not easily. Python's high level data types, dynamic typing of objects and
-run-time invocation of the interpreter (using :func:`eval` or :keyword:`exec`)
-together mean that a "compiled" Python program would probably consist mostly of
-calls into the Python run-time system, even for seemingly simple operations like
-``x+1``.
-
-Several projects described in the Python newsgroup or at past `Python
-conferences <https://www.python.org/community/workshops/>`_ have shown that this
-approach is feasible, although the speedups reached so far are only modest
-(e.g. 2x). Jython uses the same strategy for compiling to Java bytecode. (Jim
-Hugunin has demonstrated that in combination with whole-program analysis,
-speedups of 1000x are feasible for small demo programs. See the proceedings
-from the `1997 Python conference
-<http://legacy.python.org/workshops/1997-10/proceedings/>`_ for more information.)
-
-Internally, Python source code is always translated into a bytecode
-representation, and this bytecode is then executed by the Python virtual
-machine. In order to avoid the overhead of repeatedly parsing and translating
-modules that rarely change, this byte code is written into a file whose name
-ends in ".pyc" whenever a module is parsed. When the corresponding .py file is
-changed, it is parsed and translated again and the .pyc file is rewritten.
-
-There is no performance difference once the .pyc file has been loaded, as the
-bytecode read from the .pyc file is exactly the same as the bytecode created by
-direct translation. The only difference is that loading code from a .pyc file
-is faster than parsing and translating a .py file, so the presence of
-precompiled .pyc files improves the start-up time of Python scripts. If
-desired, the Lib/compileall.py module can be used to create valid .pyc files for
-a given set of modules.
-
-Note that the main script executed by Python, even if its filename ends in .py,
-is not compiled to a .pyc file. It is compiled to bytecode, but the bytecode is
-not saved to a file. Usually main scripts are quite short, so this doesn't cost
-much speed.
-
-.. XXX check which of these projects are still alive
-
-There are also several programs which make it easier to intermingle Python and C
-code in various ways to increase performance. See, for example, `Cython <http://cython.org/>`_ , `Psyco
-<http://psyco.sourceforge.net/>`_, `Pyrex

Source Code Encoding
--------------------
-By default, Python source files are treated as encoded in UTF-8. In that
-encoding, characters of most languages in the world can be used simultaneously
-in string literals, identifiers and comments --- although the standard library
-only uses ASCII characters for identifiers, a convention that any portable code
-should follow. To display all these characters properly, your editor must
-recognize that the file is UTF-8, and it must use a font that supports all the
-characters in the file.
-
+By default, Python source files are treated as encoded in ASCII.
To declare an encoding other than the default one, a special comment line
should be added as the *first* line of the file. The syntax is as follows::
>>> 'Py' 'thon'
'Python'
+This feature is particularly useful when you want to break long strings::
+
+ >>> text = ('Put several strings within parentheses '
+ ... 'to have them joined together.')
+ >>> text
+ 'Put several strings within parentheses to have them joined together.'
+
This only works with two literals though, not with variables or expressions::
>>> prefix = 'Py'
>>> prefix + 'thon'
'Python'
-This feature is particularly useful when you want to break long strings::
-
- >>> text = ('Put several strings within parentheses '
- ... 'to have them joined together.')
- >>> text
- 'Put several strings within parentheses to have them joined together.'
-
Strings can be *indexed* (subscripted), with the first character having index 0.
There is no separate character type; a character is simply a string of size
one::
frowned upon, since it often causes poorly readable code. However, it is okay to
use it to save typing in interactive sessions.
+If the module name is followed by :keyword:`as`, then the name
+following :keyword:`as` is bound directly to the imported module.
+
+::
+
+ >>> import fibo as fib
+ >>> fib.fib(500)
+ 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377
+
+This is effectively importing the module in the same way that ``import fibo``
+will do, with the only difference of it being available as ``fib``.
+
+It can also be used when utilising :keyword:`from` with similar effects::
+
+ >>> from fibo import fib as fibonacci
+ >>> fibonacci(500)
+ 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377

* The XML-RPC :class:`~SimpleXMLRPCServer.SimpleXMLRPCServer` and :class:`~DocXMLRPCServer.DocXMLRPCServer`
classes can now be prevented from immediately opening and binding to
- their socket by passing True as the ``bind_and_activate``
+ their socket by passing ``False`` as the *bind_and_activate*
constructor parameter. This can be used to modify the instance's
:attr:`allow_reuse_address` attribute before calling the
:meth:`server_bind` and :meth:`server_activate` methods to
created some new files that should be included.
(Fixed by Tarek Ziadé; :issue:`8688`.)
+ The ``upload`` command now longer tries to change CR end-of-line characters
+ to CRLF. This fixes a corruption issue with sdists that ended with a byte
+ equivalent to CR.
+ (Contributed by Bo Bayles in :issue:`32304`.)
+
* The :mod:`doctest` module's :const:`IGNORE_EXCEPTION_DETAIL` flag
will now ignore the name of the module containing the exception
being tested. (Patch by Lennart Regebro; :issue:`7490`.)
maintenance release.
+Two new environment variables for debug mode
+--------------------------------------------
+
+In debug mode, the ``[xxx refs]`` statistic is not written by default, the
+:envvar:`PYTHONSHOWREFCOUNT` environment variable now must also be set.
+(Contributed by Victor Stinner; :issue:`31733`.)
+
+When Python is compiled with ``COUNT_ALLOC`` defined, allocation counts are no
+longer dumped by default anymore: the :envvar:`PYTHONSHOWALLOCCOUNT` environment
+variable must now also be set. Moreover, allocation counts are now dumped into
+stderr, rather than stdout. (Contributed by Victor Stinner; :issue:`31692`.)

Building a Python Mac OS X distribution
=======================================
-The ``build-install.py`` script creates Python distributions, including
+WARNING
+-------
+
+The instructions in this README are incomplete and not up-to-date.
+In particular, they do not explain how to create a modern flat installer
+package from the now obsolete bundle-format installer package produced
+by ``build-installer.py``.
+
+The ``build-installer.py`` script creates Python distributions, including
certain third-party libraries as necessary. It builds a complete
framework-based Python out-of-tree, installs it in a funny place with
$DESTROOT, massages that installation to remove .pyc files and such, creates
#!/usr/bin/env python
"""
-This script is used to build "official" universal installers on Mac OS X.
-It requires at least Mac OS X 10.5, Xcode 3, and the 10.4u SDK for
-32-bit builds. 64-bit or four-way universal builds require at least
-OS X 10.5 and the 10.5 SDK.
+This script is used to build "official" universal installers on macOS.
+
+NEW for 3.6.5:
+- support Intel 64-bit-only () and 32-bit-only installer builds
+- build and link with private Tcl/Tk 8.6 for 10.9+ builds
+- deprecate use of explicit SDK (--sdk-path=) since all but the oldest
+ versions of Xcode support implicit setting of an SDK via environment
+ variables (SDKROOT and friends, see the xcrun man page for more info).
+ The SDK stuff was primarily needed for building universal installers
+ for 10.4; so as of 3.6.5, building installers for 10.4 is no longer
+ supported with build-installer.
+- use generic "gcc" as compiler (CC env var) rather than "gcc-4.2"
Please ensure that this script keeps working with Python 2.5, to avoid
-bootstrap issues (/usr/bin/python is Python 2.5 on OSX 10.5). Sphinx,
-which is used to build the documentation, currently requires at least
-Python 2.4. However, as of Python 3.4.1, Doc builds require an external
-sphinx-build and the current versions of Sphinx now require at least
-Python 2.6.
-
-In addition to what is supplied with OS X 10.5+ and Xcode 3+, the script
-requires an installed third-party version of
-Tcl/Tk 8.4 (for OS X 10.4 and 10.5 deployment targets) or Tcl/TK 8.5
+bootstrap issues (/usr/bin/python is Python 2.5 on OSX 10.5). Doc builds
+use current versions of Sphinx and require a reasonably current python3.
+Sphinx and dependencies are installed into a venv using the python3's pip
+so will fetch them from PyPI if necessary. Since python3 is now used for
+Sphinx, build-installer.py should also be converted to use python3!
+
+For 10.9 or greater deployment targets, build-installer builds and links
+with its own copy of Tcl/Tk 8.5 and the rest of this paragraph does not
+apply. Otherwise, build-installer requires an installed third-party version
+of Tcl/Tk 8.4 (for OS X 10.4 and 10.5 deployment targets) or Tcl/TK 8.5
(for 10.6 or later) installed in /Library/Frameworks. When installed,
the Python built by this script will attempt to dynamically link first to
Tcl and Tk frameworks in /Library/Frameworks if available otherwise fall
back to the ones in /System/Library/Framework. For the build, we recommend
-installing the most recent ActiveTcl 8.4 or 8.5 version.
-
-32-bit-only installer builds are still possible on OS X 10.4 with Xcode 2.5
-and the installation of additional components, such as a newer Python
-(2.5 is needed for Python parser updates) and for the documentation
-build either svn (pre-3.4.1) or sphinx-build (3.4.1 and later).
+installing the most recent ActiveTcl 8.5 or 8.4 version, depending
+on the deployment target. The actual version linked to depends on the
+path of /Library/Frameworks/{Tcl,Tk}.framework/Versions/Current.

+\i0 or later. (This ReadMe was installed with the
\i $MACOSX_DEPLOYMENT_TARGET
-\i0 variant. Unless you are installing to an 10.5 system or you need to build applications that can run on 10.5 systems, use the 10.6 variant if possible. There are some additional operating system functions that are supported starting with 10.6 and you may see better performance using 64-bit mode. By default, Python will automatically run in 64-bit mode if your system supports it. Also see
-\i Certificate verification and OpenSSL

+\i0 variant.) Previous Python 2.7.x releases provided the 10.6 or later installer and a 10.5 or later 32-bit-only variant. If you are running on macOS 10.9 or later and if you have no need for compatibility with older systems, use the 10.9 variant. Use the 10.6 variant if you are running on macOS 10.6 through 10.8, if you need to maintain compatibility with previous 2.7.x releases, or if you want to produce standalone applications that can run on systems from 10.6. The Pythons installed by these installers are built with private copies of some third-party libraries not included with or newer than those in macOS itself.

This meant that packages installed with the system Python 2.7 could also be used by the user-installed Python 2.7. While sometimes convenient, this also often caused confusion with the implicit coupling between the two Python instances. Separately, as of macOS 10.12, Apple changed the layout of the system site-packages directory,

-Python 2.7.9 includes a number of network security enhancements that have been approved for inclusion in Python 2.7 maintenance releases. {\field{\*\fldinst{HYPERLINK "https://www.python.org/dev/peps/pep-0476/"}}{\fldrslt PEP 476}} changes several standard library modules, like
-\i httplib
-\i0 ,
-\i urllib2
-\i0 , and
-\i xmlrpclib
-\i0 , to by default verify certificates presented by servers over secure (TLS) connections. The verification is performed by the OpenSSL libraries that Python is linked to. Prior to 2.7.9, the python.org installers dynamically linked with Apple-supplied OpenSSL libraries shipped with OS X. OS X provides a multiple level security framework that stores trust certificates in system and user keychains managed by the
-\i Keychain Access
-\i0 application and the
-\i security
-\i0 command line utility.\
-\
-For OS X 10.5, Apple provides
-\i OpenSSL 0.9.7
-\i0 libraries. This version of Apple's OpenSSL
-\b does not
-\b0 use the certificates from the system security framework, even when used on newer versions of OS X. Instead it consults a traditional OpenSSL concatenated certificate file (
-\i cafile
-\i0 ) or certificate directory (
-\i capath
-\i0 ), located in
-\f1 /System/Library/OpenSSL
-\f0 . These directories are typically empty and not managed by OS X; you must manage them yourself or supply your own SSL contexts. OpenSSL 0.9.7 is obsolete by current security standards, lacking a number of important features found in later versions. Among the problems this causes is the inability to verify higher-security certificates now used by python.org services, including
-\i t{\field{\*\fldinst{HYPERLINK "https://pypi.python.org/pypi"}}{\fldrslt he Python Package Index, PyPI}}
-\i0 . To solve this problem, as of 2.7.9 the
-\i 10.5+ 32-bit-only python.org variant
-\i0 is linked with a private copy of
-\i OpenSSL 1.0
-\i0 ; it consults the same default certificate directory,
-\f1 /System/Library/OpenSSL
-\f0 . As before, it is still necessary to manage certificates yourself when you use this Python variant and, with certificate verification now enabled by default, you may now need to take additional steps to ensure your Python programs have access to CA certificates you trust. If you use this Python variant to build standalone applications with third-party tools like {\field{\*\fldinst{HYPERLINK "https://pypi.python.org/pypi/py2app/"}}{\fldrslt
-\f1 py2app}}, you may now need to bundle CA certificates in them or otherwise supply non-default SSL contexts.\
-\
-For OS X 10.6+, Apple also provides
-\i OpenSSL
-\i0
-\i 0.9.8 libraries
-\i0 . Apple's 0.9.8 version includes an important additional feature: if a certificate cannot be verified using the manually administered certificates in
-\f1 /System/Library/OpenSSL
-\f0 , the certificates managed by the system security framework In the user and system keychains are also consulted (using Apple private APIs). For this reason, for 2.7.9 the
-\i 64-bit/32-bit 10.6+ python.org variant
-\i0 continues to be dynamically linked with Apple's OpenSSL 0.9.8 since it was felt that the loss of the system-provided certificates and management tools outweighs the additional security features provided by newer versions of OpenSSL. This will likely change in future releases of the python.org installers as Apple has deprecated use of the system-supplied OpenSSL libraries. If you do need features from newer versions of OpenSSL, there are third-party OpenSSL wrapper packages available through
-\i PyPI
-\i0 .\

-\f1 pip
-\f0 included with 2.7.9 has its own default certificate store for verifying download connections.\

If the optional directory argument is specified the framework is installed

The optional argument specifies which OS X SDK should be used to perform the

- on OS X 10.5 or later, you can specify ``/`` to use the installed system

available.
-The option ``--enable-universalsdk`` has an optional argument to specify an

In general, universal builds depend on specific features provided by the
Apple-supplied compilers and other build tools included in Apple's Xcode
development tools. You should install Xcode and the command line tools
component appropriate for the OS X release you are running on. See the
-Python Developer's Guide (http://docs.python.org/devguide/setup.html)

for more information.
2.1 Flavors of universal binaries
.................................
It is possible to build a number of flavors of the universal binary build,
-the default is a 32-bit only binary (i386 and ppc). Note that starting with
-Xcode 4, the build tools no longer support ppc. The flavor can be
-specified using the option ``--with-universal-archs=VALUE``. The following
+the default is a 32-bit only binary (i386 and ppc) in build environments that
+support ppc (10.4 with Xcode 2, 10.5 and 10.6 with Xcode 3) or an
+Intel-32/-64-bit binary (i386 and X86_64) in build environments that do not
+support ppc (Xcode 4 on 10.6 and later systems). The flavor can be specified
+using the configure option ``--with-universal-archs=VALUE``. The following
values are available:

from a Mac OS X application bundle (".app").
While it is technically possible to create a .app without using frameworks you
will have to do the work yourself if you really want this.
A second reason for using frameworks is that they put Python-related items in

+Security
+--------
+
+- bpo-32997: A regex in fpformat was vulnerable to catastrophic
+ backtracking. This regex was a potential DOS vector (REDOS). Based on
+ typical uses of fpformat the risk seems low. The regex has been refactored
+ and is now safe. Patch by Jamie Davis.
+
+- bpo-32981: Regexes in difflib and poplib were vulnerable to catastrophic
+ backtracking. These regexes formed potential DOS vectors (REDOS). They
+ have been refactored. This resolves CVE-2018-1060 and CVE-2018-1061. Patch
+ by Jamie Davis.
+
+- bpo-31339: Rewrite time.asctime() and time.ctime(). Backport and adapt the
+ _asctime() function from the master branch to not depend on the
+ implementation of asctime() and ctime() from the external C library. This
+ change fixes a bug when Python is run using the musl C library.
+
+- bpo-30730: Prevent environment variables injection in subprocess on
+ Windows. Prevent passing other environment variables and command
+ arguments.
+
+- bpo-30694: Upgrade expat copy from 2.2.0 to 2.2.1 to get fixes of multiple
+ security vulnerabilities including: CVE-2017-9233 (External entity
+ infinite loop DoS), CVE-2016-9063 (Integer overflow, re-fix),
+ CVE-2016-0718 (Fix regression bugs from 2.2.0's fix to CVE-2016-0718) and
+ CVE-2012-0876 (Counter hash flooding with SipHash). Note: the
+ CVE-2016-5300 (Use os- specific entropy sources like getrandom) doesn't
+ impact Python, since Python already gets entropy from the OS to set the
+ expat secret using ``XML_SetHashSalt()``.
+
+- bpo-30500: Fix urllib.splithost() to correctly parse fragments. For
+ example, ``splithost('//127.0.0.1#@evil.com/')`` now correctly returns the
+ ``127.0.0.1`` host, instead of treating ``@evil.com`` as the host in an
+ authentification (``login@host``).
+
+- bpo-29591: Update expat copy from 2.1.1 to 2.2.0 to get fixes of
+ CVE-2016-0718 and CVE-2016-4472. See
+ https://sourceforge.net/p/expat/bugs/537/ for more information.
Core and Builtins
-----------------
-- bpo-30657: Fixed possible integer overflow in PyString_DecodeEscape.
- Patch by Jay Bosamiya.
+- bpo-33026: Fixed jumping out of "with" block by setting f_lineno.
+
+- bpo-17288: Prevent jumps from 'return' and 'exception' trace events.
+
+- bpo-18533: ``repr()`` on a dict containing its own ``viewvalues()`` or
+ ``viewitems()`` no longer raises ``RuntimeError``. Instead, use ``...``,
+ as for other recursive structures. Patch by Ben North.
+
+- bpo-10544: Yield expressions are now deprecated in comprehensions and
+ generator expressions when checking Python 3 compatibility. They are still
+ permitted in the definition of the outermost iterable, as that is
+ evaluated directly in the enclosing scope.
+
+- bpo-32137: The repr of deeply nested dict now raises a RecursionError
+ instead of crashing due to a stack overflow.
+
+- bpo-20047: Bytearray methods partition() and rpartition() now accept only
+ bytes-like objects as separator, as documented. In particular they now
+ raise TypeError rather of returning a bogus result when an integer is
+ passed as a separator.

+ allocations statistics are now dumped into stderr rather than stdout.
+
+- bpo-31478: Prevent unwanted behavior in `_random.Random.seed()` in case
+ the argument has a bad ``__abs__()`` method. Patch by Oren Milman.
+
+- bpo-31530: Fixed crashes when iterating over a file on multiple threads.
+
+- bpo-31490: Fix an assertion failure in `ctypes` class definition, in case
+ the class has an attribute whose name is specified in ``_anonymous_`` but
+ not in ``_fields_``. 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-31343: Include sys/sysmacros.h for major(), minor(), and makedev().
+ GNU C libray plans to remove the functions from sys/types.h.
+
+- bpo-31311: Fix a crash in the ``__setstate__()`` method of
+ `ctypes._CData`, in case of a bad ``__dict__``. 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-31095: Fix potential crash during GC caused by ``tp_dealloc`` which
+ doesn't call ``PyObject_GC_UnTrack()``.
+
+- bpo-30657: Fixed possible integer overflow in PyString_DecodeEscape. Patch
+ by Jay Bosamiya.

- non-interned or unicode attribute names. Based on patch by Eryk Sun.
+- bpo-25794: Fixed type.__setattr__() and type.__delattr__() for non-
+ interned or unicode attribute names. Based on patch by Eryk Sun.
- bpo-29935: Fixed error messages in the index() method of tuple and list
when pass indices of wrong type.
- bpo-28598: Support __rmod__ for subclasses of str being called before
- str.__mod__. Patch by Martijn Pieters.

+ only the last field is quoted. Patch by Jake Davis.
+
+- bpo-32647: The ctypes module used to depend on indirect linking for
+ dlopen. The shared extension is now explicitly linked against libdl on

+ file size. Fixed hang of all threads with inaccessible NFS server. Patch
+ by Nir Soffer.
+
+- bpo-32110: ``codecs.StreamReader.read(n)`` now returns not more than *n*
+ characters/bytes for non-negative *n*. This makes it compatible with
+ ``read()`` methods of other file-like objects.
+
+- bpo-21149: Silence a `'NoneType' object is not callable` in
+ `_removeHandlerRef` error that could happen when a logging Handler is
+ destroyed as part of cyclic garbage collection during process shutdown.
+
+- bpo-31764: Prevent a crash in ``sqlite3.Cursor.close()`` in case the

-===========================
+- bpo-31474: Fix -Wint-in-bool-context warnings in PyMem_MALLOC and

+
+- bpo-29243: Prevent unnecessary rebuilding of Python during ``make test``,

+
+- bpo-32903: Fix a memory leak in os.chdir() on Windows if the current
+ directory is set to a UNC path.
+
+- bpo-30855: Bump Tcl/Tk to 8.5.19.
+
+- bpo-30450: Pull build dependencies from GitHub rather than svn.python.org.
+
+macOS
+-----
+
+- bpo-32726: Provide an additional, more modern macOS installer variant that
+ supports macOS 10.9+ systems in 64-bit mode only. Upgrade the supplied
+ third-party libraries to OpenSSL 1.0.2n and SQLite 3.22.0. The 10.9+
+ installer now supplies its own private copy of Tcl/Tk 8.6.8.
+
+- bpo-24414: Default macOS deployment target is now set by ``configure`` to
+ the build system's OS version (as is done by Python 3), not ``10.4``;
+ override with, for example, ``./configure MACOSX_DEPLOYMENT_TARGET=10.4``.
+
+- bpo-17128: All 2.7 macOS installer variants now supply their own version
+ of ``OpenSSL 1.0.2``; the Apple-supplied SSL libraries and root
+ certificates are not longer used. The ``Installer Certificate`` command
+ in ``/Applications/Python 2.7`` may be used to download and install a
+ default set of root certificates from the third-party ``certifi`` package.
+
+- bpo-11485: python.org macOS Pythons no longer supply a default SDK value
+ (e.g. ``-isysroot /``) or specific compiler version default (e.g.
+ ``gcc-4.2``) when building extension modules. Use ``CC``, ``SDKROOT``,
+ and ``DEVELOPER_DIR`` environment variables to override compilers or to
+ use an SDK. See Apple's ``xcrun`` man page for more info.
+
+- bpo-33184: Update macOS installer build to use OpenSSL 1.0.2o.
+
+Tools/Demos
+-----------
+
+- bpo-31920: Fixed handling directories as arguments in the ``pygettext``
+ script. Based on patch by Oleg Krasnikov.
+
+- bpo-30109: Fixed Tools/scripts/reindent.py for non-ASCII files. It now
+ processes files as binary streams. This also fixes "make reindent".
+
+- bpo-24960: 2to3 and lib2to3 can now read pickled grammar files using
+ pkgutil.get_data() rather than probing the filesystem. This lets 2to3 and
+ lib2to3 work when run from a zipfile.
+
+C API
+-----
+
+- bpo-20891: Fix PyGILState_Ensure(). When PyGILState_Ensure() is called in
+ a non-Python thread before PyEval_InitThreads(), only call
+ PyEval_InitThreads() after calling PyThreadState_New() to fix a crash.
+
+- bpo-31626: When Python is built in debug mode, the memory debug hooks now
+ fail with a fatal error if realloc() fails to shrink a memory block,
+ because the debug hook just erased freed bytes without keeping a copy of
+ them.
+
+
+What's New in Python 2.7.14 release candidate 1?
+================================================
+
+*Release date: 2017-08-26*
+
+Security
+--------
+
+- bpo-30947: Upgrade libexpat embedded copy from version 2.2.1 to 2.2.3 to
+ get security fixes.
+
+Core and Builtins
+-----------------
+
+- bpo-30765: Avoid blocking in pthread_mutex_lock() when
+ PyThread_acquire_lock() is asked not to block.
+
+Library
+-------
+
+- bpo-31135: ttk: Fix LabeledScale and OptionMenu destroy() method. 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 `copy_reg._slotnames()` mangled attribute calculation for
+ classes whose name begins with an underscore. Patch by Shane Harvey.
+
+- bpo-29519: Fix weakref spewing exceptions during interpreter shutdown when
+ used with a rare combination of multiprocessing and custom codecs.
+
+- bpo-30119: ftplib.FTP.putline() now throws ValueError on commands that
+ contains CR or LF. Patch by Dong-hee Na.
+
+- bpo-30595: multiprocessing.Queue.get() with a timeout now polls its reader
+ in non- blocking mode if it succeeded to aquire the lock but the acquire
+ took longer than the timeout.
+
+- bpo-29902: Py3k deprecation warning now is emitted when pickling or
+ copying some builtin and extension objects that don't support pickling
+ explicitly and are pickled incorrectly by default (like memoryview or
+ staticmethod). This is a TypeError in Python 3.6.
+
+- bpo-29854: Fix segfault in readline when using readline's history-size
+ option. Patch by Nir Soffer.
+
+- bpo-30807: signal.setitimer() may disable the timer when passed a tiny
+ value.
+
+ Tiny values (such as 1e-6) are valid non-zero values for setitimer(),
+ which is specified as taking microsecond-resolution intervals. However, on
+ some platform, our conversion routine could convert 1e-6 into a zero
+ interval, therefore disabling the timer instead of (re-)scheduling it.
+
+Tests
+-----
+
+- bpo-30715: Address ALPN callback changes for OpenSSL 1.1.0f. The latest
+ version behaves like OpenSSL 1.0.2 and no longer aborts handshake.
+
+- bpo-30822: Fix regrtest command line parser to allow passing -u
+ extralargefile to run test_zipfile64.
+
+- bpo-30283: regrtest: Enhance regrtest and backport features from the
+ master branch.
+
+ Add options: --coverage, --testdir, --list-tests (list test files, don't
+ run them), --list-cases (list test identifiers, don't run them,
+ :issue:`30523`), --matchfile (load a list of test filters from a text
+ file, :issue:`30540`), --slowest (alias to --slow).
+
+ Enhance output: add timestamp, test result, currently running tests,
+ "Tests result: xxx" summary with total duration, etc.
+
+ Fix reference leak hunting in regrtest, --huntrleaks: regrtest now warms
+ up caches, create explicitly all internal singletons which are created on
+ demand to prevent false positives when checking for reference leaks.
+ (:issue:`30675`).

+- bpo-7117: ``repr(x)`` for a float x returns a result based on the shortest

- (with round-half-to-even rounding mode). Previously it gave a string based on
- rounding x to 17 decimal digits. repr(x) for a complex number behaves
- similarly. On platforms where the correctly-rounded strtod and dtoa code is
- not supported (see below), repr is unchanged.
-
-- Issue #7117: On almost all platforms: float-to-string and string-to-float
- conversions within Python are now correctly rounded. Places these conversions
- occur include: str for floats and complex numbers; the float and complex
- constructors; old-style and new-style numeric formatting; serialization and
- deserialization of floats and complex numbers using marshal, pickle and json;
- parsing of float and imaginary literals in Python code; Decimal-to-float
- conversion.
-
- The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
- providing correctly-rounded strtod and dtoa C functions. This code is
- supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
- the C compiler. There may be a small number of platforms on which correct
- operation of this code cannot be guaranteed, so the code is not used: notably,
- this applies to platforms where the C double format is not IEEE 754 binary64,
- and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
- and Python's configure script is unable to determine how to change the FPU
- precision. On these platforms conversions use the platform strtod and dtoa,
- as before.

- test_support.bind_port() has been fixed such that it will always

- previous implementation, especially if socket options had been set

- the socket it's been passed. This currently only applies to
- Windows. This option prevents any other sockets from binding to the
- host/port we've bound to, thus removing the possibility of the
- 'non-deterministic' behaviour, as Microsoft puts it, that occurs
- when a second SOCK_STREAM socket binds and accepts to a host/port

-"""Run Python tests with multiple installations of OpenSSL
-
-The script
-
- (1) downloads OpenSSL tar bundle
- (2) extracts it to ../openssl/src/openssl-VERSION/
- (3) compiles OpenSSL
- (4) installs OpenSSL into ../openssl/VERSION/
- (5) forces a recompilation of Python modules using the
- header and library files from ../openssl/VERSION/
- (6) runs Python's test suite
-
-The script must be run with Python's build directory as current working
-directory:
-
- ./python Tools/ssl/test_multiple_versions.py
-
-The script uses LD_RUN_PATH, LD_LIBRARY_PATH, CPPFLAGS and LDFLAGS to bend
-search paths for header files and shared libraries. It's known to work on
-Linux with GCC 4.x.
