- opcode that they may contain. Patch by Petr Viktorin, Serhiy Storchaka,
- and Nick Coghlan.
-
-- Issue #28598: Support __rmod__ for subclasses of str being called before

-Library
--------
-
-- bpo-30879: os.listdir() and os.scandir() now emit bytes names when called
- with bytes-like argument.
-
-- bpo-30746: Prohibited the '=' character in environment variable names in
- ``os.putenv()`` and ``os.spawn*()``.

- 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).

- cases when a package is only shipped with bytecodes. Patch by
- Alexandru Ardelean.

-
-- Issue #19771: Also in runpy and the "-m" option, omit the irrelevant
- message ". . . is a package and cannot be directly executed" if the package
- could not even be initialized (e.g. due to a bad ``*.pyc`` file).

-
-
-What's New in Python 3.5.1 release candidate 1?
-===============================================
-
-Release date: 2015-11-22
-
-Core and Builtins
------------------
-
-- Issue #25630: Fix a possible segfault during argument parsing in functions
- that accept filesystem paths.
-
-- Issue #23564: Fixed a partially broken sanity check in the _posixsubprocess
- internals regarding how fds_to_pass were passed to the child. The bug had
- no actual impact as subprocess.py already avoided it.
-
-- Issue #25388: Fixed tokenizer crash when processing undecodable source code
- with a null byte.
-
-- Issue #25462: The hash of the key now is calculated only once in most
- operations in C implementation of OrderedDict.
-
-- Issue #22995: Default implementation of __reduce__ and __reduce_ex__ now
- rejects builtin types with not defined __new__.
-
-- Issue #25555: Fix parser and AST: fill lineno and col_offset of "arg" node
- when compiling AST from Python objects.
-
-- Issue #24802: Avoid buffer overreads when int(), float(), compile(), exec()
- and eval() are passed bytes-like objects. These objects are not
- necessarily terminated by a null byte, but the functions assumed they were.
-
-- Issue #24726: Fixed a crash and leaking NULL in repr() of OrderedDict that
- was mutated by direct calls of dict methods.
-
-- Issue #25449: Iterating OrderedDict with keys with unstable hash now raises
- KeyError in C implementations as well as in Python implementation.
-
-- Issue #25395: Fixed crash when highly nested OrderedDict structures were
- garbage collected.
-
-- Issue #25274: sys.setrecursionlimit() now raises a RecursionError if the new
- recursion limit is too low depending at the current recursion depth. Modify
- also the "lower-water mark" formula to make it monotonic. This mark is used
- to decide when the overflowed flag of the thread state is reset.
-
-- Issue #24402: Fix input() to prompt to the redirected stdout when
- sys.stdout.fileno() fails.
-
-- Issue #24806: Prevent builtin types that are not allowed to be subclassed from
- being subclassed through multiple inheritance.
-
-- Issue #24848: Fixed a number of bugs in UTF-7 decoding of misformed data.
-
-- Issue #25280: Import trace messages emitted in verbose (-v) mode are no
- longer formatted twice.
-
-- Issue #25003: On Solaris 11.3 or newer, os.urandom() now uses the
- getrandom() function instead of the getentropy() function. The getentropy()
- function is blocking to generate very good quality entropy, os.urandom()
- doesn't need such high-quality entropy.
-
-- Issue #25182: The stdprinter (used as sys.stderr before the io module is
- imported at startup) now uses the backslashreplace error handler.
-
-- Issue #25131: Make the line number and column offset of set/dict literals and
- comprehensions correspond to the opening brace.
-
-- Issue #25150: Hide the private _Py_atomic_xxx symbols from the public
- Python.h header to fix a compilation error with OpenMP. PyThreadState_GET()
- becomes an alias to PyThreadState_Get() to avoid ABI incompatibilies.
-
-Library
--------
-
-- Issue #25626: Change three zlib functions to accept sizes that fit in
- Py_ssize_t, but internally cap those sizes to UINT_MAX. This resolves a
- regression in 3.5 where GzipFile.read() failed to read chunks larger than 2
- or 4 GiB. The change affects the zlib.Decompress.decompress() max_length
- parameter, the zlib.decompress() bufsize parameter, and the
- zlib.Decompress.flush() length parameter.
-
-- Issue #25583: Avoid incorrect errors raised by os.makedirs(exist_ok=True)
- when the OS gives priority to errors such as EACCES over EEXIST.
-
-- Issue #25593: Change semantics of EventLoop.stop() in asyncio.
-
-- Issue #6973: When we know a subprocess.Popen process has died, do

- anything as they could potentially signal a different process.
-
-- Issue #25590: In the Readline completer, only call getattr() once per
- attribute.
-
-- Issue #25498: Fix a crash when garbage-collecting ctypes objects created

- Mirroring the existing asyncio create_server method the reuseaddr option
- for datagram sockets defaults to True if the O/S is 'posix' (except if the
- 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 #25135: Make deque_clear() safer by emptying the deque before clearing.
- This helps avoid possible reentrancy issues.
-

- avoid compatibility shims.
-
-- Issue #25092: Fix datetime.strftime() failure when errno was already set to
- EINVAL.
-
-- Issue #23517: Fix rounding in fromtimestamp() and utcfromtimestamp() methods
- of datetime.datetime: microseconds are now rounded to nearest with ties
- going to nearest even integer (ROUND_HALF_EVEN), instead of being rounding
- towards minus infinity (ROUND_FLOOR). 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 #25155: Fix datetime.datetime.now() and datetime.datetime.utcnow() on
- Windows to support date after year 2038. It was a regression introduced in
- Python 3.5.0.
-
-- Issue #25108: Omitted internal frames in traceback functions print_stack(),
- format_stack(), and extract_stack() called without arguments.
-
-- Issue #25118: Fix a regression of Python 3.5.0 in os.waitpid() on Windows.
-
-- 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 #25060: Correctly compute stack usage of the BUILD_MAP opcode.
-
-- 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 #23144: Make sure that HTMLParser.feed() returns all the data, even
- when convert_charrefs is True.
-

-IDLE
-----
-
-- Issue #15348: Stop the debugger engine (normally in a user process)
- before closing the debugger window (running in the IDLE process).
- This prevents the RuntimeErrors that were being caught and ignored.
-
-- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
- debugger is active (15347); b) closing the debugger with the [X] button
- (15348); and c) activating the debugger when already active (24455).
- 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.
-

- Strings, comments, keywords, ... are still green, red, orange, ... .
- To use it with IDLEs released before November 2015, hit the
- 'Save as New Custom Theme' button and enter a new name,
- such as 'Custom Dark'. The custom theme will work with any IDLE
- release, and can be modified.
-
-- Issue #25224: README.txt is now an idlelib index for IDLE developers and
- curious users. The previous user content is now in the IDLE doc chapter.
- 'IDLE' now means 'Integrated Development and Learning Environment'.

- to get the name of the code.
-
-- Issue #21669: With the aid of heuristics in SyntaxError.__init__, the
- parser now attempts to generate more meaningful (or at least more search
- engine friendly) error messages when "exec" and "print" are used as
- statements.

- and does not require to carry long the spark.py parser-generator library;
- spark.py was removed from the source base.

- now display special message when and only when there are failures.
-
-- Issue #21141: The Windows build process no longer attempts to find Perl,
- instead relying on OpenSSL source being configured and ready to build. The
- ``PCbuild\build_ssl.py`` script has been re-written and re-named to

-
-- Issue #21233: Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(),
- PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) is now using
- ``calloc()`` instead of ``malloc()`` for large objects which is faster and
- use less memory.

-
-- asyncio: Refactoring and fixes: BaseEventLoop.sock_connect() raises an
- error if the address is not resolved; use __slots__ in Handle and
- TimerHandle; as_completed() and wait() raise TypeError if the passed
- list of Futures is a single Future; call_soon() and other 'call_*()'
- functions raise TypeError if the passed callback is a coroutine
- function; _ProactorBasePipeTransport uses _FlowControlMixin;

-===============================================
-
-Release date: 2014-02-10
-
-Core and Builtins
------------------
-
-- Issue #19255: The builtins module is restored to initial value before
- cleaning other modules. The sys and builtins modules are cleaned last.
-
-- Issue #20588: Make Python-ast.c C89 compliant.
-
-- Issue #20437: Fixed 22 potential bugs when deleting object references.
-
-- Issue #20500: Displaying an exception at interpreter shutdown no longer
- risks triggering an assertion failure in PyObject_Str.
-
-- 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
- for known non-text encodings at stream construction time. The existing
- output type checks remain in place to deal with unmarked third party
- codecs.
-
-- Issue #17162: Add PyType_GetSlot.
-
-- Issue #20162: Fix an alignment issue in the siphash24() hash function which
- caused a crash on PowerPC 64-bit (ppc64).
-
-Library
--------
-
-- Issue #20530: The signatures for slot builtins have been updated
- to reflect the fact that they only accept positional-only arguments.
-
-- Issue #20517: Functions in the os module that accept two filenames
- now register both filenames in the exception on failure.
-
-- Issue #20563: The ipaddress module API is now considered stable.
-
-- Issue #14983: email.generator now always adds a line end after each MIME
- boundary marker, instead of doing so only when there is an epilogue. This
- fixes an RFC compliance bug and solves an issue with signed MIME parts.
-
-- Issue #20540: Fix a performance regression (vs. Python 3.2) when layering
- a multiprocessing Connection over a TCP socket. For small payloads, Nagle's
- algorithm would introduce idle delays before the entire transmission of a
- message.
-
-- Issue #16983: the new email header parsing code will now decode encoded words
- that are (incorrectly) surrounded by quotes, and register a defect.
-
-- Issue #19772: email.generator no longer mutates the message object when
- doing a down-transform from 8bit to 7bit CTEs.
-
-- Issue #20536: the statistics module now correctly handle Decimal instances
- with positive exponents
-
-- Issue #18805: the netmask/hostmask parsing in ipaddress now more reliably
- 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
- some interoperability issues that arose with the previous approach of
- 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.
-
-- Issue #20013: Some imap servers disconnect if the current mailbox is
- deleted, and imaplib did not handle that case gracefully. Now it
- 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 #20476: If a non-compat32 policy is used with any of the email parsers,
- EmailMessage is now used as the factory class. The factory class should
- really come from the policy; that will get fixed in 3.5.
-
-- Issue #19920: TarFile.list() no longer fails when outputs a listing
- containing non-encodable characters. Based on patch by Vajrasky Kok.
-
-- Issue #20515: Fix NULL pointer dereference introduced by issue #20368.
-

- settings in the default pip configuration file.
-
-- Issue #20426: When passing the re.DEBUG flag, re.compile() displays the
- debug output every time it is called, regardless of the compilation cache.
-
-- Issue #20368: The null character now correctly passed from Tcl to Python.
- Improved error handling in variables-related commands.
-
-- Issue #20435: Fix _pyio.StringIO.getvalue() to take into account newline
- translation settings.
-
-- tracemalloc: Fix slicing traces and fix slicing a traceback.
-
-- Issue #20354: Fix an alignment issue in the tracemalloc module on 64-bit
- platforms. Bug seen on 64-bit Linux when using "make profile-opt".

-- Issue #17159: inspect.signature now accepts duck types of functions,
- which adds support for Cython functions. Initial patch by Stefan Behnel.
-
-- Issue #18801: Fix inspect.classify_class_attrs to correctly classify
- object.__new__ and object.__init__.
-
-- Fixed cmath.isinf's name in its argument parsing code.
-
-- 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
- wait_for(f, None); don't log broken/disconnected pipes; use
- ValueError instead of assert for forbidden subprocess_{shell,exec}
- arguments; added a convenience API for subprocess management; added
- StreamReader.at_eof(); properly handle duplicate coroutines/futures

-
-- Issue #20105: the codec exception chaining now correctly sets the
- traceback of the original exception as its __traceback__ attribute.
-

-
-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.

- 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.

- with two new required arguments: "typedef" and "type_object".
-
-- Issue #20390: Argument Clinic: If __new__ or __init__ functions didn't use
- kwargs (or args), the PyArg_NoKeywords (or PyArg_NoPositional) calls

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

- input; reworded docs to clarify that an integer type should define both __int__
- and __index__.
-
-- Issue #19787: PyThread_set_key_value() now always set the value. In Python
- 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

-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 object destructors. So "unclosed file" resource
- warnings are now correctly 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".
-

-
-- 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 #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.
