topics = {'assert': u'\nThe "assert" statement\n**********************\n\nAssert statements are a convenient way to insert debugging assertions\ninto a program:\n\n assert_stmt ::= "assert" expression ["," expression]\n\nThe simple form, "assert expression", is equivalent to\n\n if __debug__:\n if not expression: raise AssertionError\n\nThe extended form, "assert expression1, expression2", is equivalent to\n\n if __debug__:\n if not expression1: raise AssertionError(expression2)\n\nThese equivalences assume that "__debug__" and "AssertionError" refer\nto the built-in variables with those names. In the current\nimplementation, the built-in variable "__debug__" is "True" under\nnormal circumstances, "False" when optimization is requested (command\nline option -O). The current code generator emits no code for an\nassert statement when optimization is requested at compile time. Note\nthat it is unnecessary to include the source code for the expression\nthat failed in the error message; it will be displayed as part of the\nstack trace.\n\nAssignments to "__debug__" are illegal. The value for the built-in\nvariable is determined when the interpreter starts.\n',
'assignment': u'\nAssignment statements\n*********************\n\nAssignment statements are used to (re)bind names to values and to\nmodify attributes or items of mutable objects:\n\n assignment_stmt ::= (target_list "=")+ (expression_list | yield_expression)\n target_list ::= target ("," target)* [","]\n target ::= identifier\n | "(" target_list ")"\n | "[" target_list "]"\n | attributeref\n | subscription\n | slicing\n | "*" target\n\n(See section *Primaries* for the syntax definitions for\n*attributeref*, *subscription*, and *slicing*.)\n\nAn assignment statement evaluates the expression list (remember that\nthis can be a single expression or a comma-separated list, the latter\nyielding a tuple) and assigns the single resulting object to each of\nthe target lists, from left to right.\n\nAssignment is defined recursively depending on the form of the target\n(list). When a target is part of a mutable object (an attribute\nreference, subscription or slicing), the mutable object must\nultimately perform the assignment and decide about its validity, and\nmay raise an exception if the assignment is unacceptable. The rules\nobserved by various types and the exceptions raised are given with the\ndefinition of the object types (see section *The standard type\nhierarchy*).\n\nAssignment of an object to a target list, optionally enclosed in\nparentheses or square brackets, is recursively defined as follows.\n\n* If the target list is a single target: The object is assigned to\n that target.\n\n* If the target list is a comma-separated list of targets: The\n object must be an iterable with the same number of items as there\n are targets in the target list, and the items are assigned, from\n left to right, to the corresponding targets.\n\n * If the target list contains one target prefixed with an\n asterisk, called a "starred" target: The object must be a sequence\n with at least as many items as there are targets in the target\n list, minus one. The first items of the sequence are assigned,\n from left to right, to the targets before the starred target. The\n final items of the sequence are assigned to the targets after the\n starred target. A list of the remaining items in the sequence is\n then assigned to the starred target (the list can be empty).\n\n * Else: The object must be a sequence with the same number of\n items as there are targets in the target list, and the items are\n assigned, from left to right, to the corresponding targets.\n\nAssignment of an object to a single target is recursively defined as\nfollows.\n\n* If the target is an identifier (name):\n\n * If the name does not occur in a "global" or "nonlocal" statement\n in the current code block: the name is bound to the object in the\n current local namespace.\n\n * Otherwise: the name is bound to the object in the global\n namespace or the outer namespace determined by "nonlocal",\n respectively.\n\n The name is rebound if it was already bound. This may cause the\n reference count for the object previously bound to the name to reach\n zero, causing the object to be deallocated and its destructor (if it\n has one) to be called.\n\n* If the target is a target list enclosed in parentheses or in\n square brackets: The object must be an iterable with the same number\n of items as there are targets in the target list, and its items are\n assigned, from left to right, to the corresponding targets.\n\n* If the target is an attribute reference: The primary expression in\n the reference is evaluated. It should yield an object with\n assignable attributes; if this is not the case, "TypeError" is\n raised. That object is then asked to assign the assigned object to\n the given attribute; if it cannot perform the assignment, it raises\n an exception (usually but not necessarily "AttributeError").\n\n Note: If the object is a class instance and the attribute reference\n occurs on both sides of the assignment operator, the RHS expression,\n "a.x" can access either an instance attribute or (if no instance\n attribute exists) a class attribute. The LHS target "a.x" is always\n set as an instance attribute, creating it if necessary. Thus, the\n two occurrences of "a.x" do not necessarily refer to the same\n attribute: if the RHS expression refers to a class attribute, the\n LHS creates a new instance attribute as the target of the\n assignment:\n\n class Cls:\n x = 3 # class variable\n inst = Cls()\n inst.x = inst.x + 1 # writes inst.x as 4 leaving Cls.x as 3\n\n This description does not necessarily apply to descriptor\n attributes, such as properties created with "property()".\n\n* If the target is a subscription: The primary expression in the\n reference is evaluated. It should yield either a mutable sequence\n object (such as a list) or a mapping object (such as a dictionary).\n Next, the subscript expression is evaluated.\n\n If the primary is a mutable sequence object (such as a list), the\n subscript must yield an integer. If it is negative, the sequence\'s\n length is added to it. The resulting value must be a nonnegative\n integer less than the sequence\'s length, and the sequence is asked\n to assign the assigned object to its item with that index. If the\n index is out of range, "IndexError" is raised (assignment to a\n subscripted sequence cannot add new items to a list).\n\n If the primary is a mapping object (such as a dictionary), the\n subscript must have a type compatible with the mapping\'s key type,\n and the mapping is then asked to create a key/datum pair which maps\n the subscript to the assigned object. This can either replace an\n existing key/value pair with the same key value, or insert a new\n key/value pair (if no key with the same value existed).\n\n For user-defined objects, the "__setitem__()" method is called with\n appropriate arguments.\n\n* If the target is a slicing: The primary expression in the\n reference is evaluated. It should yield a mutable sequence object\n (such as a list). The assigned object should be a sequence object\n of the same type. Next, the lower and upper bound expressions are\n evaluated, insofar they are present; defaults are zero and the\n sequence\'s length. The bounds should evaluate to integers. If\n either bound is negative, the sequence\'s length is added to it. The\n resulting bounds are clipped to lie between zero and the sequence\'s\n length, inclusive. Finally, the sequence object is asked to replace\n the slice with the items of the assigned sequence. The length of\n the slice may be different from the length of the assigned sequence,\n thus changing the length of the target sequence, if the target\n sequence allows it.\n\n**CPython implementation detail:** In the current implementation, the\nsyntax for targets is taken to be the same as for expressions, and\ninvalid syntax is rejected during the code generation phase, causing\nless detailed error messages.\n\nAlthough the definition of assignment implies that overlaps between\nthe left-hand side and the right-hand side are \'simultanenous\' (for\nexample "a, b = b, a" swaps two variables), overlaps *within* the\ncollection of assigned-to variables occur left-to-right, sometimes\nresulting in confusion. For instance, the following program prints\n"[0, 2]":\n\n x = [0, 1]\n i = 0\n i, x[i] = 1, 2 # i is updated, then x[i] is updated\n print(x)\n\nSee also: **PEP 3132** - Extended Iterable Unpacking\n\n The specification for the "*target" feature.\n\n\nAugmented assignment statements\n===============================\n\nAugmented assignment is the combination, in a single statement, of a\nbinary operation and an assignment statement:\n\n augmented_assignment_stmt ::= augtarget augop (expression_list | yield_expression)\n augtarget ::= identifier | attributeref | subscription | slicing\n augop ::= "+=" | "-=" | "*=" | "/=" | "//=" | "%=" | "**="\n | ">>=" | "<<=" | "&=" | "^=" | "|="\n\n(See section *Primaries* for the syntax definitions of the last three\nsymbols.)\n\nAn augmented assignment evaluates the target (which, unlike normal\nassignment statements, cannot be an unpacking) and the expression\nlist, performs the binary operation specific to the type of assignment\non the two operands, and assigns the result to the original target.\nThe target is only evaluated once.\n\nAn augmented assignment expression like "x += 1" can be rewritten as\n"x = x + 1" to achieve a similar, but not exactly equal effect. In the\naugmented version, "x" is only evaluated once. Also, when possible,\nthe actual operation is performed *in-place*, meaning that rather than\ncreating a new object and assigning that to the target, the old object\nis modified instead.\n\nUnlike normal assignments, augmented assignments evaluate the left-\nhand side *before* evaluating the right-hand side. For example, "a[i]\n+= f(x)" first looks-up "a[i]", then it evaluates "f(x)" and performs\nthe addition, and lastly, it writes the result back to "a[i]".\n\nWith the exception of assigning to tuples and multiple targets in a\nsingle statement, the assignment done by augmented assignment\nstatements is handled the same way as normal assignments. Similarly,\nwith the exception of the possible *in-place* behavior, the binary\noperation performed by augmented assignment is the same as the normal\nbinary operations.\n\nFor targets which are attribute references, the same *caveat about\nclass and instance attributes* applies as for regular assignments.\n',
'atom-identifiers': u'\nIdentifiers (Names)\n*******************\n\nAn identifier occurring as an atom is a name. See section\n*Identifiers and keywords* for lexical definition and section *Naming\nand binding* for documentation of naming and binding.\n\nWhen the name is bound to an object, evaluation of the atom yields\nthat object. When a name is not bound, an attempt to evaluate it\nraises a "NameError" exception.\n\n**Private name mangling:** When an identifier that textually occurs in\na class definition begins with two or more underscore characters and\ndoes not end in two or more underscores, it is considered a *private\nname* of that class. Private names are transformed to a longer form\nbefore code is generated for them. The transformation inserts the\nclass name, with leading underscores removed and a single underscore\ninserted, in front of the name. For example, the identifier "__spam"\noccurring in a class named "Ham" will be transformed to "_Ham__spam".\nThis transformation is independent of the syntactical context in which\nthe identifier is used. If the transformed name is extremely long\n(longer than 255 characters), implementation defined truncation may\nhappen. If the class name consists only of underscores, no\ntransformation is done.\n',

- platform is Cygwin). Patch by Chris Laws.
-
-- Issue #25304: Add asyncio.run_coroutine_threadsafe(). This lets you
- submit a coroutine to a loop from another thread, returning a
- concurrent.futures.Future. By Vincent Michel.
-
-- Issue #25319: When threading.Event is reinitialized, the underlying condition
- should use a regular lock rather than a recursive lock.
-
-- Issue #25232: Fix CGIRequestHandler to split the query from the URL at the
- first question mark (?) rather than the last. Patch from Xiang Zhang.
-
-- Issue #24657: Prevent CGIRequestHandler from collapsing slashes in the

-
-- Issue #22609: Constructor of collections.UserDict now accepts the self keyword
- argument.
-
-- Issue #25262. Added support for BINBYTES8 opcode in Python implementation of

-- Issue #19143: platform module now reads Windows version from kernel32.dll to
- avoid compatibility shims.

- of datetime.datetime: microseconds are now rounded to nearest with ties
- going to nearest even integer (ROUND_HALF_EVEN), instead of being rounding
- towards zero (ROUND_DOWN). It's important that these methods use the same
- rounding mode than datetime.timedelta to keep the property:
- (datetime(1970,1,1) + timedelta(seconds=t)) == datetime.utcfromtimestamp(t).
- It also the rounding mode used by round(float) for example.
-
-- Issue #24684: socket.socket.getaddrinfo() now calls
- PyUnicode_AsEncodedString() instead of calling the encode() method of the
- host, to handle correctly custom string with an encode() method which doesn't
- return a byte string. The encoder of the IDNA codec is now called directly
- instead of calling the encode() method of the string.
-
-- Issue #24982: shutil.make_archive() with the "zip" format now adds entries
- for directories (including empty directories) in ZIP file.
-
-- Issue #24857: Comparing call_args to a long sequence now correctly returns a
- boolean result instead of raising an exception. Patch by A Kaptur.
-
-- Issue #25019: Fixed a crash caused by setting non-string key of expat parser.
- Based on patch by John Leitch.
-
-- Issue #24917: time_strftime() buffer over-read.
-
-- Issue #23144: Make sure that HTMLParser.feed() returns all the data, even
- when convert_charrefs is True.
-
-- Issue #16180: Exit pdb if file has syntax error, instead of trapping user
- in an infinite loop. Patch by Xavier de Gaye.
-
-- Issue #21112: Fix regression in unittest.expectedFailure on subclasses.
- Patch from Berker Peksag.
-
-- Issue #24931: Instances of subclasses of namedtuples have their own __dict__
- which breaks the inherited __dict__ property and breaks the _asdict() method.
- Removed the __dict__ property to prevent the conflict and fixed _asdict().
-
-- Issue #24764: cgi.FieldStorage.read_multi() now ignores the Content-Length
- header in part headers. Patch written by Peter Landry and reviewed by Pierre
- Quentel.

-IDLE

- The patch by Mark Roseman does this by making two changes.
- 1. Suspend and resume the gui.interaction method with the tcl vwait
- mechanism intended for this purpose (instead of root.mainloop & .quit).
- 2. In gui.run, allow any existing interaction to terminate first.

-
-- Issue #20538: UTF-7 incremental decoder produced inconsistent string when
- input was truncated in BASE64 section.
-
-- Issue #20404: io.TextIOWrapper (and hence the open() builtin) now uses the
- internal codec marking system added for issue #19619 to throw LookupError

- output type checks remain in place to deal with unmarked third party
- codecs.
-
-- Issue #17162: Add PyType_GetSlot.
-

- filters out illegal values and correctly allows any valid prefix length.
-
-- Issue #20481: For at least Python 3.4, the statistics module will require
- that all inputs for a single operation be of a single consistent type, or
- else a mixed of ints and a single other consistent type. This avoids

- coercing to a suitable common type.
-
-- Issue #20478: the statistics module now treats collections.Counter inputs
- like any other iterable.
-
-- Issue #17369: get_filename was raising an exception if the filename
- parameter's RFC2231 encoding was broken in certain ways. This was
- a regression relative to python2.

- handles the 'bye' correctly.
-
-- Issue #20531: Revert 3.4 version of fix for #19063, and apply the 3.3
- version. That is, do *not* raise an error if unicode is passed to
- email.message.Message.set_payload.

-- Issue #20311, #20452: poll and epoll now round the timeout away from zero,
- instead of rounding towards zero, in select and selectors modules:
- select.epoll.poll(), selectors.PollSelector.poll() and
- selectors.EpollSelector.poll(). For example, a timeout of one microsecond
- (1e-6) is now rounded to one millisecondi (1e-3), instead of being rounded to
- zero. However, the granularity property and asyncio's resolution feature
- were removed again.
-
-- asyncio: Some refactoring; various fixes; add write flow control to
- unix pipes; Future.set_exception() instantiates the exception
- argument if it is a class; improved proactor pipe transport; support

-
-Tools/Demos
------------
-
-- Issue #20530: Argument Clinic's signature format has been revised again.
- The new syntax is highly human readable while still preventing false
- positives. The syntax also extends Python syntax to denote "self" and
- positional-only parameters, allowing inspect.Signature objects to be
- totally accurate for all supported builtins in Python 3.4.
-
-- Issue #20456: Argument Clinic now observes the C preprocessor conditional
- compilation statements of the C files it parses. When a Clinic block is
- inside a conditional code, it adjusts its output to match, including
- automatically generating an empty methoddef macro.
-
-- Issue #20456: Cloned functions in Argument Clinic now use the correct
- name, not the name of the function they were cloned from, for text
- strings inside generated code.
-
-- Issue #20456: Fixed Argument Clinic's test suite and "--converters" feature.
-
-- Issue #20456: Argument Clinic now allows specifying different names
- for a parameter in Python and C, using "as" on the parameter line.
-
-- Issue #20326: Argument Clinic now uses a simple, unique signature to
- annotate text signatures in docstrings, resulting in fewer false
- positives. "self" parameters are also explicitly marked, allowing
- inspect.Signature() to authoritatively detect (and skip) said parameters.
-
-- Issue #20326: Argument Clinic now generates separate checksums for the
- input and output sections of the block, allowing external tools to verify
- that the input has not changed (and thus the output is not out-of-date).
-
-Build
------
-
-- Issue #20465: Update SQLite shipped with OS X installer to 3.8.3.
-
-C-API
------
-
-- Issue #20517: Added new functions allowing OSError exceptions to reference
- two filenames instead of one: PyErr_SetFromErrnoWithFilenameObjects() and
- PyErr_SetExcFromWindowsErrWithFilenameObjects().
-
-Documentation
--------------
-
-- Issue #20488: Change wording to say importlib is *the* implementation of
- import instead of just *an* implementation.
-
-- Issue #6386: Clarify in the tutorial that specifying a symlink to execute
- means the directory containing the executed script and not the symlink is
- added to sys.path.
-
-
-What's New in Python 3.4.0 Beta 3?
-==================================
-
-Release date: 2014-01-26
-
-Core and Builtins
------------------
-
-- Issue #20189: Four additional builtin types (PyTypeObject,
- PyMethodDescr_Type, _PyMethodWrapper_Type, and PyWrapperDescr_Type)
- have been modified to provide introspection information for builtins.
-
-- Issue #17825: Cursor "^" is correctly positioned for SyntaxError and
- IndentationError.
-
-- Issue #2382: SyntaxError cursor "^" is now written at correct position in most
- cases when multibyte characters are in line (before "^"). This still not
- works correctly with wide East Asian characters.
-
-- Issue #18960: The first line of Python script could be executed twice when
- the source encoding was specified on the second line. Now the source encoding
- declaration on the second line isn't effective if the first line contains
- anything except a comment. 'python -x' works now again with files with the
- source encoding declarations, and can be used to make Python batch files
- on Windows.
-
-Library
--------

-
-- Issue #20317: ExitStack.__exit__ could create a self-referential loop if an
- exception raised by a cleanup operation already had its context set
- correctly (for example, by the @contextmanager decorator). The infinite

-
-- Issue #20390: Argument Clinic now fails if you have required parameters after
- optional parameters.
-

- 3.3, the function did nothing if the key already exists (if the current value
- is a non-NULL pointer).
-
-- Issue #14432: Remove the thread state field from the frame structure. Fix a
- crash when a generator is created in a C thread that is destroyed while the
- generator is still used. The issue was that a generator contains a frame, and
- the frame kept a reference to the Python state of the destroyed C thread. The
- crash occurs when a trace function is setup.
-
-- Issue #19576: PyGILState_Ensure() now initializes threads. At startup, Python
- has no concrete GIL. If PyGILState_Ensure() is called from a new thread for

-
-- Issue #19850: Set SA_RESTART in asyncio when registering a signal
- handler to limit EINTR occurrences.

- Original patch by Simon Sapin.
-
-- Issue #19946: multiprocessing now uses runpy to initialize __main__ in
- child processes when necessary, allowing it to correctly handle scripts
- without suffixes and submodules that use explicit relative imports or
- otherwise rely on parent modules being correctly imported prior to
- execution.
-
-- Issue #19921: When Path.mkdir() is called with parents=True, any missing
- parent is created with the default permissions, ignoring the mode argument
- (mimicking the POSIX "mkdir -p" command).
-
-- Issue #19887: Improve the Path.resolve() algorithm to support certain
- symlink chains.
-
-- Issue #19912: Fixed numerous bugs in ntpath.splitunc().

-
-- Issue #19063: if a Charset's body_encoding was set to None, the email

- reference cycles between frames and the _Outcome instance.
-
-- Issue #17429: platform.linux_distribution() now decodes files from the UTF-8
- encoding with the surrogateescape error handler, instead of decoding from the
- locale encoding in strict mode. It fixes the function on Fedora 19 which is
- probably the first major distribution release with a non-ASCII name. Patch
- written by Toshio Kuratomi.
-
-- Issue #19343: Expose FreeBSD-specific APIs in resource module. Original
- patch by Koobs.
-
-- Issue #19929: Call os.read with 32768 within subprocess.Popen.communicate

-
-- Issue #19927: Add __eq__ to path-based loaders in importlib.
-
-- Issue #19827: On UNIX, setblocking() and settimeout() methods of

-What's New in Python 3.4.0 Beta 1?
-==================================
-
-Release date: 2013-11-24
-
-Core and Builtins
------------------
-
-- Use the repr of a module name in more places in import, especially
- exceptions.
-
-- Issue #19619: str.encode, bytes.decode and bytearray.decode now use an
- internal API to throw LookupError for known non-text encodings, rather
- than attempting the encoding or decoding operation and then throwing a
- TypeError for an unexpected output type. (The latter mechanism remains
- in place for third party non-text encodings)
-
-- Issue #19183: Implement PEP 456 'secure and interchangeable hash algorithm'.
- Python now uses SipHash24 on all major platforms.
-
-- Issue #12892: The utf-16* and utf-32* encoders no longer allow surrogate code
- points (U+D800-U+DFFF) to be encoded. The utf-32* decoders no longer decode
- byte sequences that correspond to surrogate code points. The surrogatepass
- error handler now works with the utf-16* and utf-32* codecs. Based on
- patches by Victor Stinner and Kang-Hao (Kenny) Lu.
-
-- Issue #17806: Added keyword-argument support for "tabsize" to
- str/bytes.expandtabs().
-
-- Issue #17828: Output type errors in str.encode(), bytes.decode() and
- bytearray.decode() now direct users to codecs.encode() or codecs.decode()
- as appropriate.
-
-- Issue #17828: The interpreter now attempts to chain errors that occur in
- codec processing with a replacement exception of the same type that
- includes the codec name in the error message. It ensures it only does this
- when the creation of the replacement exception won't lose any information.
-
-- Issue #19466: Clear the frames of daemon threads earlier during the
- Python shutdown to call objects destructors. So "unclosed file" resource
- warnings are now corretly emitted for daemon threads.
-
-- Issue #19514: Deduplicate some _Py_IDENTIFIER declarations.
- Patch by Andrei Dorian Duma.
-
-- Issue #17936: Fix O(n**2) behaviour when adding or removing many subclasses
- of a given type.
-
-- Issue #19428: zipimport now handles errors when reading truncated or invalid
- ZIP archive.
-
-- Issue #18408: Add a new PyFrame_FastToLocalsWithError() function to handle
- exceptions when merging fast locals into f_locals of a frame.
- PyEval_GetLocals() now raises an exception and return NULL on failure.
-
-- Issue #19369: Optimized the usage of __length_hint__().
-
-- Issue #18603: Ensure that PyOS_mystricmp and PyOS_mystrnicmp are in the
- Python executable and not removed by the linker's optimizer.
-
-- Issue #19306: Add extra hints to the faulthandler module's stack
- dumps that these are "upside down".
-
-Library
--------

- computes the stack effect of bytecode instructions.
-
-- Issue #19735: Implement private function ssl._create_stdlib_context() to
- create SSLContext objects in Python's stdlib module. It provides a single
- configuration point and makes use of SSLContext.load_default_certs().
-
-- Issue #16203: Add re.fullmatch() function and regex.fullmatch() method,
- which anchor the pattern at both ends of the string to match.
- Original patch by Matthew Barnett.
-
-- Issue #13592: Improved the repr for regular expression pattern objects.
- Based on patch by Hugo Lopes Tavares.

-
-- Issue #19673: Add pathlib to the stdlib as a provisional module (PEP 428).
-
-- Issue #16596: pdb in a generator now properly skips over yield and

-- Issue #18138: Implement cadata argument of SSLContext.load_verify_location()
- to load CA certificates and CRL from memory. It supports PEM and DER
- encoded strings.
-
-- Issue #18775: Add name and block_size attribute to HMAC object. They now
- provide the same API elements as non-keyed cryptographic hash functions.
-
-- Issue #17276: MD5 as default digestmod for HMAC is deprecated. The HMAC
- module supports digestmod names, e.g. hmac.HMAC('sha1').

-
-What's New in Python 3.4.0 Alpha 4?
-===================================
-
-Release date: 2013-10-20
-
-Core and Builtins
------------------
-
-- Issue #19301: Give classes and functions that are explicitly marked global a
- global qualname.
-
-- Issue #19279: UTF-7 decoder no longer produces illegal strings.
-
-- Issue #16612: Add "Argument Clinic", a compile-time preprocessor for

- directory.
-
-- Issue #18416: importlib.machinery.PathFinder now treats '' as the cwd and
- importlib.machinery.FileFinder no longer special-cases '' to '.'. This leads
- to modules imported from cwd to now possess an absolute file path for
- __file__ (this does not affect modules specified by path on the CLI but it
- does affect -m/runpy). It also allows FileFinder to be more consistent by not
- having an edge case.
-

- if an error occurred), instead of a string allocated by PyMem_Malloc() or
- PyMem_Realloc().

-
-- Fix macro expansion of _PyErr_OCCURRED(), and make sure to use it in at
- least one place so as to avoid regressions.

- like curses.ACS_HLINE: the Python function addch(int) and addch(bytes) is now
- calling the C function waddch()/mvwaddch() (as it was done in Python 3.2),
- instead of wadd_wch()/mvwadd_wch(). The Python function addch(str) is still
- calling the C function wadd_wch()/mvwadd_wch() if the Python curses is linked
- to libncursesw.

-
-Core and Builtins
------------------
-
-- Issue #14172: Fix reference leak when marshalling a buffer-like object
- (other than a bytes object).
-
-- Issue #13521: dict.setdefault() now does only one lookup for the given key,
- making it "atomic" for many purposes. Patch by Filip Gruszczyński.
-
-- PEP 409, Issue #6210: "raise X from None" is now supported as a means of
- suppressing the display of the chained exception context. The chained
- context still remains available as the __context__ attribute.

- The ndarray test object from _testbuffer.c implements all aspects of
- PEP-3118, so further development towards the complete implementation
- of the PEP can proceed in a test-driven manner.
-
- Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review
- and many ideas.
-
-- Issue #12834: Fix incorrect results of memoryview.tobytes() for

- Distutils-based packages with C extension modules may fail because
- Apple has removed gcc-4.2, the version used to build python.org
- 64-bit/32-bit Pythons. If the user does not explicitly override
- the default C compiler by setting the CC environment variable,
- Distutils will now attempt to compile extension modules with clang
- if gcc-4.2 is required but not found. Also as a convenience, if
- the user does explicitly set CC, substitute its value as the default
- compiler in the Distutils LDSHARED configuration variable for OS X.
- (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
- SDK, neither of which are available in Xcode 4. This change does not
- attempt to override settings to support their use with Xcode 4.)

-
-- Issue #10968: Remove indirection in threading. The public names (Event,
- Condition, etc.) used to be factory functions returning instances of hidden

-
-- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
- check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
- interpreter process. This could cause failures in non-Distutils subprocesses
- and was unreliable since tests or user programs could modify the interpreter
- environment after Distutils set it. Instead, have Distutils set the
- deployment target only in the environment of each build subprocess. It is
- still possible to globally override the default by setting
- MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
- greater or equal to the default value, the value with which the interpreter
- was built. Also, implement the same handling in packaging.

-
-- Issue #12141: Install copies of template C module file so that
- test_build_ext of test_distutils and test_command_build_ext of

+On OS X 10.7 and 10.6 with Xcode 4.2, building Distutils-based packages with

+used to build python.org 64-bit/32-bit Pythons. If the user does not
+explicitly override the default C compiler by setting the CC environment
+variable, Distutils will now attempt to compile extension modules with clang
+if gcc-4.2 is required but not found. Also as a convenience, if the user
+does explicitly set CC, substitute its value as the default compiler in the
+Distutils LDSHARED configuration variable for OS X. (Note, the python.org
+32-bit-only Pythons use gcc-4.0 and the 10.4u SDK, neither of which are

+ * HISTORY:
+ *
+ * 2017-07-25 (Vadim Zeitlin)
+ * - Fix use of SIPHASH_MAIN macro
+ *
+ * 2017-07-05 (Sebastian Pipping)
+ * - Use _SIP_ULL macro to not require a C++11 compiler if compiled as C++
+ * - Add const qualifiers at two places
+ * - Ensure <=80 characters line length (assuming tab width 4)
+ *
+ * 2017-06-23 (Victor Stinner)
+ * - Address Win64 compile warnings
+ *
+ * 2017-06-18 (Sebastian Pipping)
+ * - Clarify license note in the header
+ * - Address C89 issues:
+ * - Stop using inline keyword (and let compiler decide)
+ * - Replace _Bool by int
+ * - Turn macro siphash24 into a function
+ * - Address invalid conversion (void pointer) by explicit cast
+ * - Address lack of stdint.h for Visual Studio 2003 to 2008
+ * - Always expose sip24_valid (for self-tests)
+ *
+ * 2012-11-04 - Born. (William Ahern)

+ * SipHash-2-4 takes as input two 64-bit words as the key, some number of
+ * message bytes, and outputs a 64-bit word as the message digest. This
+ * implementation employs two data structures: a struct sipkey for
+ * representing the key, and a struct siphash for representing the hash
+ * state.
+ *
+ * For converting a 16-byte unsigned char array to a key, use either the
+ * macro sip_keyof or the routine sip_tokey. The former instantiates a
+ * compound literal key, while the latter requires a key object as a
+ * parameter.
+ *
+ * unsigned char secret[16];
+ * arc4random_buf(secret, sizeof secret);
+ * struct sipkey *key = sip_keyof(secret);
+ *
+ * For hashing a message, use either the convenience macro siphash24 or the
+ * routines sip24_init, sip24_update, and sip24_final.
+ *
+ * struct siphash state;
+ * void *msg;
+ * size_t len;
+ * uint64_t hash;
+ *
+ * sip24_init(&state, key);
+ * sip24_update(&state, msg, len);
+ * hash = sip24_final(&state);
+ *
+ * or
+ *
+ * hash = siphash24(msg, len, key);
+ *
+ * To convert the 64-bit hash value to a canonical 8-byte little-endian
+ * binary representation, use either the macro sip_binof or the routine
+ * sip_tobin. The former instantiates and returns a compound literal array,
+ * while the latter requires an array object as a parameter.
+ * --------------------------------------------------------------------------
+ * NOTES:
+ *
+ * o Neither sip_keyof, sip_binof, nor siphash24 will work with compilers
+ * lacking compound literal support. Instead, you must use the lower-level
+ * interfaces which take as parameters the temporary state objects.
+ *
+ * o Uppercase macros may evaluate parameters more than once. Lowercase
+ * macros should not exhibit any such side effects.

+ This BYFOUR code accesses the passed unsigned char * buffer with a 32-bit

+ fundamentally different types won't ever point to the same memory. This can
+ manifest as a problem only if one of the pointers is written to. This code
+ only reads from those pointers. So long as this code remains isolated in
+ this compilation unit, there won't be a problem. For this reason, this code
+ should not be copied and pasted into a compilation unit in which other code
