|
||
format unit.

|
||
|
||
- Issue #27039: Fixed bytearray.remove() for values greater than 127. Patch by
|
||
Joe Jevnik.
|
||
|
||
- Issue #23640: int.from_bytes() no longer bypasses constructors for subclasses.
|
||
|
||
- Issue #26811: gc.get_objects() no longer contains a broken tuple with NULL
|
||
pointer.
|
||
|
||
- Issue #20120: Use RawConfigParser for .pypirc parsing,
|
||
removing support for interpolation unintentionally added
|
||
with move to Python 3. Behavior no longer does any
|
||
interpolation in .pypirc files, matching behavior in Python
|
||
2.7 and Setuptools 19.0.
|
||
|
||
- Issue #26659: Make the builtin slice type support cycle collection.
|
||
|
||
- Issue #26718: super.__init__ no longer leaks memory if called multiple times.
|
||
NOTE: A direct call of super.__init__ is not endorsed!
|
||
|
||
- Issue #25339: PYTHONIOENCODING now has priority over locale in setting the
|
||
error handler for stdin and stdout.
|
||
|
||
- Issue #26494: Fixed crash on iterating exhausting iterators.
|
||
Affected classes are generic sequence iterators, iterators of str, bytes,

views and os.scandir() iterator.
|

|
||
Python source code file, only the first one is taken to account.

|
||
string longer than 1 character. Regression introduced in Python 3.5.0.
|
||
|
||
- Issue #22836: Ensure exception reports from PyErr_Display() and
|
||
PyErr_WriteUnraisable() are sensible even when formatting them produces

|
||
|
||
- Issue #26154: Add a new private _PyThreadState_UncheckedGet() function to get
|
||
the current Python thread state, but don't issue a fatal error if it is NULL.
|
||
This new function must be used instead of accessing directly the
|
||
_PyThreadState_Current variable. The variable is no more exposed since
|
||
Python 3.5.1 to hide the exact implementation of atomic C types, to avoid
|
||
compiler issues.
|
||
|
||
- Issue #26194: Deque.insert() gave odd results for bounded deques that had
|
||
reached their maximum size. Now an IndexError will be raised when attempting
|
||
to insert into a full deque.
|
||
|
||
- Issue #25843: When compiling code, don't merge constants if they are equal
|
||
but have a different types. For example, ``f1, f2 = lambda: 1, lambda: 1.0``
|
||
is now correctly compiled to two different functions: ``f1()`` returns ``1``
|
||
(``int``) and ``f2()`` returns ``1.0`` (``int``), even if ``1`` and ``1.0``
|
||
are equal.

|
||
|
||
- Issue #25973: Fix segfault when an invalid nonlocal statement binds a name
|
||
starting with two underscores.
|
||
|
||
- Issue #22995: Instances of extension types with a state that aren't
|
||
subclasses of list or dict and haven't implemented any pickle-related
|
||
methods (__reduce__, __reduce_ex__, __getnewargs__, __getnewargs_ex__,
|
||
or __getstate__), can no longer be pickled. Including memoryview.
|
||
|
||
- Issue #20440: Massive replacing unsafe attribute setting code with special
|
||
macro Py_SETREF.
|
||
|
||
- Issue #25766: Special method __bytes__() now works in str subclasses.
|
||
|
||
- Issue #25421: __sizeof__ methods of builtin types now use dynamic basic size.
|
||
This allows sys.getsize() to work correctly with their subclasses with
|
||
__slots__ defined.
|
||
|
||
- Issue #25709: Fixed problem with in-place string concatenation and utf-8
|
||
cache.
|
||
|
||
- Issue #27147: Mention PEP 420 in the importlib docs.

|
||
__getattr__.
|
||

|
||
__bytes__, __trunc__, and __float__ returning instances of subclasses of
|
||
bytes, int, and float to subclasses of bytes, int, and float correspondingly.
|
||
|
||
- Issue #26478: Fix semantic bugs when using binary operators with dictionary
|
||
views and tuples.
|
||
|
||
- Issue #26171: Fix possible integer overflow and heap corruption in
|
||
zipimporter.get_data().
|
||
|
||
- Issue #25660: Fix TAB key behaviour in REPL with readline.
|
||
|
||
- Issue #25887: Raise a RuntimeError when a coroutine object is awaited
|
||
more than once.
|
||
|
||
- Issue #27243: Update the __aiter__ protocol: instead of returning
|
||
an awaitable that resolves to an asynchronous iterator, the asynchronous
|
||
iterator should be returned directly. Doing the former will trigger a
|
||
PendingDeprecationWarning.

||
doing partial writes, but this is deprecated.

|
||
|
||
- Issue #17214: The "urllib.request" module now percent-encodes non-ASCII
|
||
bytes found in redirect target URLs. Some servers send Location header
|
||
fields with non-ASCII bytes, but "http.client" requires the request target
|

to be ASCII-encodable, otherwise a UnicodeEncodeError is raised. Based on
|

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

|
||
|
||
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.
|
||
|
||

|
||
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:

||
|
||
- 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.

|
||
of stdin (0), stdout (1) or stderr (2) is closed while Python is creating
|
||
sys.stdin, sys.stdout and sys.stderr objects. These attributes are now set
|
||
to None if the creation of the object failed, instead of raising an OSError
|
||
exception. Initial patch written by Marco Paolini.
|
||
|
||
- Issue #24992: Fix error handling and a race condition (related to garbage
|
||
collection) in collections.OrderedDict constructor.

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.
|
||
|
||
- Change 'The program' to 'Your program' in an IDLE 'kill program?' message
|
||
to make it clearer that the program referred to is the currently running
|
||
user program, not IDLE itself.
|
||
|
||
- Issue #24750: Improve the appearance of the IDLE editor window status bar.
|

||
|
||
- Issue #22726: Re-activate the config dialog help button with some content
|
||
about the other buttons and the new IDLE Dark theme.
|
||
|
||
- Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme.
|
||
It is more or less IDLE Classic inverted, with a cobalt blue background.
|
||
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.
|
||

For Mac OSX, make them a 'sheet'. Patch by Mark Roseman.
|
||
|
||
- Issue #25198: Enhance the initial html viewer now used for Idle Help.
|
||
* Properly indent fixed-pitch text (patch by Mark Roseman).
|
||
* Give code snippet a very Sphinx-like light blueish-gray background.
|
||
* Re-use initial width and height set by users for shell and editor.
|
||
* When the Table of Contents (TOC) menu is used, put the section header
|
||
at the top of the screen.

|
||
- Issue #25199: Idle: add synchronization comments for future maintainers.
|
||
|
||
- Issue #16893: Replace help.txt with help.html for Idle doc display.
|
||
The new idlelib/help.html is rstripped Doc/build/html/library/idle.html.
|
||
It looks better than help.txt and will better document Idle as released.
|
||
The tkinter html viewer that works for this file was written by Mark Roseman.
|
||
The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated.
|
||
|

||
- Issue #21859: Added Python implementation of io.FileIO.
|
||
|
||

|
||

|
||
result of sendto() instead of the C int type.
|
||
|
||
- Issue #23618: :meth:`socket.socket.connect` now waits until the connection
|
||
completes instead of raising :exc:`InterruptedError` if the connection is
|
||
interrupted by signals, signal handlers don't raise an exception and the
|
||
socket is blocking or has a timeout. :meth:`socket.socket.connect` still
|
||
raise :exc:`InterruptedError` for non-blocking sockets.
|
||

|
||
- Issue #23485: select.select() is now retried automatically with the

||
recomputed timeout when interrupted by a signal, except if the signal handler

raises an exception. This change is part of the PEP 475.
|
||
|
||
- Issue #23752: When built from an existing file descriptor, io.FileIO() now
|
||
only calls fstat() once. Before fstat() was called twice, which was not
|
||
necessary.
|
||
|
||
- Issue #23704: collections.deque() objects now support __add__, __mul__, and

|
||
POT-Creation-Date header.
|

|
||
|
||
- Issue #23500: Argument Clinic is now smarter about generating the "#ifndef"
|
||
(empty) definition of the methoddef macro: it's only generated once, even
|
||
if Argument Clinic processes the same symbol multiple times, and it's emitted
|
||
at the end of all processing rather than immediately after the first use.
|
||
|
||
C API
|
||
-----
|
||

-----------------
|
||
|
||
- Issue #23573: Increased performance of string search operations (str.find,
|
||

|
||
arguments of different kinds (UCS1, UCS2, UCS4).
|
||
|
||
- Issue #23753: Python doesn't support anymore platforms without stat() or
|

|
||
|

|
||
now is non-modifiable mapping.
|
||
|
||
- Issue #23792: Ignore KeyboardInterrupt when the pydoc pager is active.

|
||
as repr().

|
||
|

|
||
creation) mode.
|
||
|

|
||
writer failed in BufferedRWPair.close().
|
||
|

|
||
Python 3.6.
|
||
|
||

|
||
- Issue #23491: Added a zipapp module to support creating executable zip

||
unnecessary copying of memoryview in gzip.GzipFile.write().
|

|
||
|
||
- Issue #23539: If body is None, http.client.HTTPConnection.request now sets

||
some web servers.
|
||
|
||
- Issue #22351: The nntplib.NNTP constructor no longer leaves the connection
|
||
and socket open until the garbage collector cleans them up. Patch by
|
||
Martin Panter.
|
||
|
||
- Issue #23704: collections.deque() objects now support methods for index(),

- Issue #23715: :func:`signal.sigwaitinfo` and :func:`signal.sigtimedwait` are
|
||
now retried when interrupted by a signal not in the *sigset* parameter, if

||
|
||

|
||
codecs, that accepted only read-only bytes-like object now accept writable
|
||
bytes-like object too.
|

- Issue #23646: If time.sleep() is interrupted by a signal, the sleep is now
|
||
retried with the recomputed delay, except if the signal handler raises an
|
||
exception (PEP 475).
|
||
|

|
||
importing a test module is now picklable.
|
||
|
||
- Issue #22181: On Linux, os.urandom() now uses the new getrandom() syscall if
|
||
available, syscall introduced in the Linux kernel 3.17. It is more reliable
|
||
and more secure, because it avoids the need of a file descriptor and waits
|
||
until the kernel has enough entropy.
|
||
|
||
- Issue #2211: Updated the implementation of the http.cookies.Morsel class.
|
||
Setting attributes key, value and coded_value directly now is deprecated.
|
||
update() and setdefault() now transform and check keys. Comparing for
|
||
equality now takes into account attributes key, value and coded_value.

|
||
Optimized checking keys and quoting values. Added new tests.

|
||
|

|
||
SSL 3.

distutils module still supports it to build extensions.
|
||
|
||
- Issue #22591: Drop support of MS-DOS, especially of the DJGPP compiler
|
||
(MS-DOS port of GCC).

|
||
separate "Programs" directory, rather than being kept in the Modules
|
||
directory.

|
||
- Issue #15759: "make suspicious", "make linkcheck" and "make doctest" in Doc/
|
||
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
|
||
``PCbuild\prepare_ssl.py``, and takes care of configuring OpenSSL source
|
||
for both 32 and 64 bit platforms. OpenSSL sources obtained from
|
||
svn.python.org will always be pre-configured and ready to build.
|
||
|
||
- Issue #21037: Add a build option to enable AddressSanitizer support.
|
||
|
||
- Issue #19962: The Windows build process now creates "python.bat" in the

|
||
- Issue #21285: Refactor and fix curses configure check to always search
|
||
in a ncursesw directory.

|
||
include directories if they aren't already being searched. This avoids
|
||
an explicit runtime library dependency.
|
||
|
||
- Issue #17861: Tools/scripts/generate_opcode_h.py automatically regenerates
|
||
Include/opcode.h from Lib/opcode.py if the latter gets any change.
|
||
|
||
- Issue #20644: OS X installer build support for documentation build changes

|
||
C API
|
||
-----
|
||
|
||
- Issue #14203: Remove obsolete support for view==NULL in PyBuffer_FillInfo(),
|
||
bytearray_getbuffer(), bytesiobuf_getbuffer() and array_buffer_getbuf().
|
||
All functions now raise BufferError in that case.
|
||
|
||
- Issue #22445: PyBuffer_IsContiguous() now implements precise contiguity
|
||
tests, compatible with NumPy's NPY_RELAXED_STRIDES_CHECKING compilation
|
||
flag. Previously the function reported false negatives for corner cases.
|
||

|
||
no dynamically allocated bases.
|
||

||
|
||
- Issue #18395: Rename ``_Py_char2wchar()`` to :c:func:`Py_DecodeLocale`,
|
||
rename ``_Py_wchar2char()`` to :c:func:`Py_EncodeLocale`, and document
|
||
these functions.
|
||
|
||
- 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.
|
||
|
||
- Issue #20942: PyImport_ImportFrozenModuleObject() no longer sets __file__ to
|
||
match what importlib does; this affects _frozen_importlib as well as any
|
||
module loaded using imp.init_frozen().
|
||
|
||
Documentation
|
||
-------------
|
||
|
||

|
||
7159 instead of obsoleted RFC 4627.
|
||
|

||
|
||

||

|
||
PurePath.with_suffix().
|
||
|
||
- Issue #19407: New package installation and distribution guides based on
|
||
the Python Packaging Authority tools. Existing guides have been retained
|
||
as legacy links from the distutils docs, as they still contain some
|
||
required reference material for tool developers that isn't recorded
|
||
anywhere else.
|
||

||
-------
|
||
|
||
- Issue #23260: Update Windows installer
|
||
|
||
- The bundled version of Tcl/Tk has been updated to 8.6.3. The most visible
|
||
result of this change is the addition of new native file dialogs when
|
||
running on Windows Vista or newer. See Tcl/Tk's TIP 432 for more
|
||
information. Also, this version of Tcl/Tk includes support for Windows 10.
|
||
|
||
- Issue #17896: The Windows build scripts now expect external library sources
|
||
to be in ``PCbuild\..\externals`` rather than ``PCbuild\..\..``.
|
||
|
||
- Issue #17717: The Windows build scripts now use a copy of NASM pulled from
|
||
svn.python.org to build OpenSSL.
|
||
|
||
- Issue #21907: Improved the batch scripts provided for building Python.
|
||
|
||
- Issue #22644: The bundled version of OpenSSL has been updated to 1.0.1j.

|
||
- Issue #10747: Use versioned labels in the Windows start menu.
|
||
Patch by Olive Kilburn.
|
||
|
||
- Issue #22980: .pyd files with a version and platform tag (for example,
|
||
".cp35-win32.pyd") will now be loaded in preference to those without tags.

Core and Builtins
|
||
-----------------
|
||
|
||
- Issue #20625: Parameter names in __annotations__ were not mangled properly.
|
||
Discovered by Jonas Wielicki, patch by Yury Selivanov.
|

|
||
shutdown.
|
||
|
||
Library
|
||
-------
|
||
|
||
- Issue #20710: The pydoc summary line no longer displays the "self" parameter
|
||
for bound methods.
|
||
|
||
- Issue #20566: Change asyncio.as_completed() to use a Queue, to
|
||
avoid O(N**2) behavior.
|
||
|
||
- Issue #20704: Implement new debug API in asyncio. Add new methods
|
||
BaseEventLoop.set_debug() and BaseEventLoop.get_debug().
|
||
Add support for setting 'asyncio.tasks._DEBUG' variable with
|
||
'PYTHONASYNCIODEBUG' environment variable.
|
||
|
||
- 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;
|
||
WriteTransport.set_write_buffer_size() calls _maybe_pause_protocol()
|
||
to consider pausing receiving if the watermark limits have changed;
|
||
fix _check_resolved_address() for IPv6 address; and other minor
|
||
improvements, along with multiple documentation updates.
|
||
|
||
- Issue #20684: Fix inspect.getfullargspec() to not to follow __wrapped__
|
||
chains. Make its behaviour consistent with bound methods first argument.
|
||
Patch by Nick Coghlan and Yury Selivanov.
|
||
|
||
- Issue #20681: Add new error handling API in asyncio. New APIs:
|

||
|
||
- Issue #20673: Implement support for UNIX Domain Sockets in asyncio.
|
||
New APIs: loop.create_unix_connection(), loop.create_unix_server(),
|
||
streams.open_unix_connection(), and streams.start_unix_server().
|
||
|
||
- Issue #20616: Add a format() method to tracemalloc.Traceback.
|
||
|
||
- Issue #19744: the ensurepip installation step now just prints a warning to
|
||
stderr rather than failing outright if SSL/TLS is unavailable. This allows
|
||
local installation of POSIX builds without SSL/TLS support.
|
||
|
||
- Issue #20594: Avoid name clash with the libc function posix_close.
|
||
|

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.
|
||
|
||
- Issue #19186: Restore namespacing of expat symbols inside the pyexpat module.
|
||
|
||
- Issue #20053: ensurepip (and hence venv) are no longer affected by the
|
||
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
|
||
in gather(), wait(), as_completed(); use a bytearray for buffering
|
||
in StreamReader; and more.
|
||
|
||
- Issue #20288: fix handling of invalid numeric charrefs in HTMLParser.
|
||
|
||
- Issue #20424: Python implementation of io.StringIO now supports lone surrogates.
|
||
|
||
- Issue #20308: inspect.signature now works on classes without user-defined
|
||
__init__ or __new__ methods.
|
||
|
||
- Issue #20372: inspect.getfile (and a bunch of other inspect functions that
|
||
use it) doesn't crash with unexpected AttributeError on classes defined in C
|
||
without __module__.
|
||
|
||
- Issue #20356: inspect.signature formatting uses '/' to separate
|
||
positional-only parameters from others.
|
||
|
||
- Issue #20223: inspect.signature now supports methods defined with
|
||
functools.partialmethods.
|
||
|
||
- Issue #19456: ntpath.join() now joins relative paths correctly when a drive
|
||
is present.
|
||
|
||
- Issue #19077: tempfile.TemporaryDirectory cleanup no longer fails when
|
||
called during shutdown. Emitting resource warning in __del__ no longer fails.
|
||
Original patch by Antoine Pitrou.

|
||
codecs.StreamReader returned incomplete data when were called after
|
||
readline() or read(size). Based on patch by Amaury Forgeot d'Arc.
|
||
|
||
- Issue #20105: the codec exception chaining now correctly sets the
|
||
traceback of the original exception as its __traceback__ attribute.
|
||
|
||
- Issue #17481: inspect.getfullargspec() now uses inspect.signature() API.
|
||
|
||
- Issue #15304: concurrent.futures.wait() can block forever even if
|
||
Futures have completed. Patch by Glenn Langford.
|
||
|
||
- Issue #14455: plistlib: fix serializing integers in the range
|
||
of an unsigned long long but outside of the range of signed long long for
|
||
binary plist files.
|
||
|
||
IDLE
|
||
----
|
||
|
||
- Issue #20406: Use Python application icons for Idle window title bars.
|
||
Patch mostly by Serhiy Storchaka.
|
||
|
||
- Update the python.gif icon for the Idle classbrowser and pathbowser
|
||
from the old green snake to the new blue and yellow snakes.
|
||
|
||
- Issue #17721: Remove non-functional configuration dialog help button until we
|
||
make it actually gives some help when clicked. Patch by Guilherme Simões.
|
||
|
||
Tests
|
||
-----
|
||
|
||
- Issue #20532: Tests which use _testcapi now are marked as CPython only.
|
||
|
||
- Issue #19920: Added tests for TarFile.list(). Based on patch by Vajrasky Kok.
|
||
|
||
- Issue #19990: Added tests for the imghdr module. Based on patch by
|
||
Claudiu Popa.
|
||
|
||
- Issue #20474: Fix test_socket "unexpected success" failures on OS X 10.7+.
|
||
|
||
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
|
||
-------
|
||
|
||
- asyncio: Various improvements and small changes not all covered by
|
||
issues listed below. E.g. wait_for() now cancels the inner task if
|
||
the timeout occcurs; tweaked the set of exported symbols; renamed
|
||
Empty/Full to QueueEmpty/QueueFull; "with (yield from lock)" now
|
||
uses a separate context manager; readexactly() raises if not enough
|
||
data was read; PTY support tweaks.
|
||
|
||
- Issue #20311: asyncio: Add a granularity attribute to BaseEventLoop: maximum
|
||
between the resolution of the BaseEventLoop.time() method and the resolution
|
||
of the selector. The granuarility is used in the scheduler to round time and
|
||
deadline.
|
||
|
||
- Issue #20311: selectors: Add a resolution attribute to BaseSelector.
|
||
|
||
- Issue #20189: unittest.mock now no longer assumes that any object for
|
||
which it could get an inspect.Signature is a callable written in Python.
|
||
Fix courtesy of Michael Foord.
|
||
|
||
- 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
|
||
loop this caused is now avoided by checking if the expected context is
|
||
already set before trying to fix it.
|
||
|
||
- Issue #20374: Fix build with GNU readline >= 6.3.

||
write complete output on close.
|
||
|
||
- Issue #20245: The open functions in the tarfile module now correctly handle
|
||
empty mode.
|
||
|
||
- Issue #20242: Fixed basicConfig() format strings for the alternative
|
||
formatting styles. Thanks to kespindler for the bug report and patch.

|
||
|
||
- Issues #20206 and #5803: Fix edge case in email.quoprimime.encode where it
|
||
truncated lines ending in a character needing encoding but no newline by
|
||
using a more efficient algorithm that doesn't have the bug.
|
||

|
||
on the second line if the first line contains anything except a comment.
|
||

|
||
|
||
Tools/Demos
|
||
-----------
|
||
|
||
- Issue #20390: Argument Clinic's "file" output preset now defaults to
|
||
"{dirname}/clinic/{basename}.h".
|
||
|
||
- Issue #20390: Argument Clinic's "class" directive syntax has been extended
|
||
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
|
||
generated are only run when the type object is an exact match.
|
||
|
||
- Issue #20390: Argument Clinic now fails if you have required parameters after
|
||
optional parameters.
|
||
|
||
- Issue #20390: Argument Clinic converters now have a new template they can

|
||
|
||
- Issue #20376: Argument Clinic now escapes backslashes in docstrings.
|
||
|
||
- Issue #20381: Argument Clinic now sanity checks the default argument when

|
||
disallowed values.
|
||
|
||
- Issue #20189: Argument Clinic now ensures that parser functions for
|
||
__new__ are always of type newfunc, the type of the tp_new slot.

|
||
the type of tp_init.
|
||

|
||
value of c_default and py_default with a class member.
|

|
||
requires them. Disable executable bits and shebang lines in test and
|

||
parsing code for functions with positional-only parameters where all arguments
|
||
are optional.
|
||
|
||
- Issue #18960: 2to3 and the findnocoding.py script now ignore the source
|
||
encoding declaration on the second line if the first line contains anything

- Issue #19723: The marker comments Argument Clinic uses have been changed
|
||
to improve readability.

What's New in Python 3.4.0 Beta 2?
|
||
==================================
|
||
|
||
Release date: 2014-01-05
|
||
|
||
Core and Builtins
|
||
-----------------
|
||
|
||
- Issue #17432: Drop UCS2 from names of Unicode functions in python3.def.
|
||
|
||
- Issue #19526: Exclude all new API from the stable ABI. Exceptions can be
|
||
made if a need is demonstrated.
|
||
|
||
- Issue #19969: PyBytes_FromFormatV() now raises an OverflowError if "%c"
|
||
argument is not in range [0; 255].
|
||
|
||
- Issue #19995: %c, %o, %x, and %X now issue a DeprecationWarning on non-integer
|
||
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
|
||
the first time and PyEval_InitThreads() was not called yet, a GIL needs to be
|
||
created.
|
||
|
||
- Issue #17576: Deprecation warning emitted now when __int__() or __index__()
|
||
return not int instance.
|
||
|
||
- Issue #19932: Fix typo in import.h, missing whitespaces in function prototypes.
|
||
|
||
- Issue #19736: Add module-level statvfs constants defined for GNU/glibc

||
|
||
- Issue #19638: Fix possible crash / undefined behaviour from huge (more than 2
|
||
billion characters) input strings in _Py_dg_strtod.
|
||
|
||

||
- Issue #19918: Fix PurePath.relative_to() under Windows.
|
||
|
||
- Issue #19422: Explicitly disallow non-SOCK_STREAM sockets in the ssl
|
||
module, rather than silently let them emit clear text data.
|
||
|
||
- Issue #20046: Locale alias table no longer contains entities which can be
|
||
calculated. Generalized support of the euro modifier.
|
||
|
||
- Issue #20027: Fixed locale aliases for devanagari locales.
|
||
|
||
- Issue #20067: Tkinter variables now work when wantobjects is false.
|
||
|
||
- Issue #19020: Tkinter now uses splitlist() instead of split() in configure
|
||
methods.
|
||
|
||
- Issue #19744: ensurepip now provides a better error message when Python is
|
||
built without SSL/TLS support (pip currently requires that support to run,
|
||
even if only operating with local wheel files)
|
||
|
||
- Issue #19734: ensurepip now ignores all pip environment variables to avoid
|
||
odd behaviour based on user configuration settings
|
||
|
||
- Fix TypeError on "setup.py upload --show-response".
|
||
|
||
- Issue #20045: Fix "setup.py register --list-classifiers".

||
|
||

|
||
the file before the method is possibly called.
|
||
|
||
- Issue #20037: Avoid crashes when opening a text file late at interpreter
|
||
shutdown.
|
||
|
||
- Issue #19967: Thanks to the PEP 442, asyncio.Future now uses a
|
||
destructor to log uncaught exceptions, instead of the dedicated
|
||
_TracebackLogger class.
|
||
|
||
- Added a Task.current_task() class method to asyncio.
|
||
|
||
- Issue #19850: Set SA_RESTART in asyncio when registering a signal
|
||
handler to limit EINTR occurrences.
|
||
|
||
- Implemented write flow control in asyncio for proactor event loop (Windows).
|
||
|
||
- Change write buffer in asyncio use to avoid O(N**2) behavior. Make
|
||
write()/sendto() accept bytearray/memoryview.
|
||
|
||
- Issue #20034: Updated alias mapping to most recent locale.alias file
|
||
from X.org distribution using makelocalealias.py.
|
||
|
||
- Issue #5815: Fixed support for locales with modifiers. Fixed support for
|
||
locale encodings with hyphens.
|
||
|
||
- Issue #20026: Fix the sqlite module to handle correctly invalid isolation
|
||
level (wrong type).
|
||
|
||
- Issue #18829: csv.Dialect() now checks type for delimiter, escapechar and
|
||
quotechar fields. Original patch by Vajrasky Kok.
|
||
|
||
- Issue #19855: uuid.getnode() on Unix now looks on the PATH for the
|
||
executables used to find the mac address, with /sbin and /usr/sbin as
|
||
fallbacks.
|
||
|
||
- Issue #20007: HTTPResponse.read(0) no more prematurely closes connection.
|
||
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 #19911: ntpath.splitdrive() now correctly processes the 'İ' character
|
||
(U+0130, LATIN CAPITAL LETTER I WITH DOT ABOVE).
|
||
|
||
- Issue #19532: python -m compileall with no filename/directory arguments now
|
||
respects the -f and -q flags instead of ignoring them.
|
||
|
||
- Issue #19623: Fixed writing to unseekable files in the aifc module.
|
||
|
||
- Issue #19946: multiprocessing.spawn now raises ImportError when the module to
|
||
be used as the main module cannot be imported.
|
||
|
||
- Issue #17919: select.poll.register() again works with poll.POLLNVAL on AIX.
|
||
Fixed integer overflow in the eventmask parameter.
|
||
|
||
- Issue #19063: if a Charset's body_encoding was set to None, the email
|
||
package would generate a message claiming the Content-Transfer-Encoding
|
||
was 7bit, and produce garbage output for the content. This now works.
|
||
A couple of other set_payload mishandlings of non-ASCII are also fixed.
|
||
In addition, calling set_payload with a string argument without
|
||
specifying a charset now raises an error (this is a new error in 3.4).
|
||
|
||
- Issue #15475: Add __sizeof__ implementations for itertools objects.

|
||
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
|
||
rather than 4096 for efficiency. A microbenchmark shows Linux and OS X
|
||
both using ~50% less cpu time this way.
|
||
|
||
- Issue #19506: Use a memoryview to avoid a data copy when piping data
|
||
to stdin within subprocess.Popen.communicate. 5-10% less cpu usage.

|
||
if the FD is closed (as long as it was registered).
|
||
|
||
- Issue #19908: pathlib now joins relative Windows paths correctly when a drive
|
||
is present. Original patch by Antoine Pitrou.

|
||
large bytes string (i.e., with size greater than 2**32-1).
|
||
|
||
- Issue #19138: doctest's IGNORE_EXCEPTION_DETAIL now allows a match when
|
||
no exception detail exists (no colon following the exception's name, or
|
||
a colon does follow but no text follows the colon).
|
||
|
||
- Issue #19927: Add __eq__ to path-based loaders in importlib.
|
||
|
||
- Issue #19827: On UNIX, setblocking() and settimeout() methods of
|
||
socket.socket can now avoid a second syscall if the ioctl() function can be
|
||
used, or if the non-blocking flag of the socket is unchanged.

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".
|
||
|
||
Library
|
||
-------
|
||
|
||
- Issue #3158: doctest can now find doctests in functions and methods
|
||

|
||
Original patch by Berker Peksag.

||
- Issue #19674: inspect.signature() now produces a correct signature
|
||
for some builtins.
|
||
|
||
- Issue #19722: Added opcode.stack_effect(), which
|
||
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.

William Mallard.
|
||
|

|
||
certificates from default stores or system stores. By default the method
|
||
loads CA certs for authentication of server certs.
|
||
|
||
- 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
|
||
yield from rather than stepping out of the generator into its
|
||
caller. (This is essential for stepping through asyncio coroutines.)
|
||
|
||
- Issue #17916: Added dis.Bytecode.from_traceback() and
|
||
dis.Bytecode.current_offset to easily display "current instruction"
|
||
markers in the new disassembly API (Patch by Claudiu Popa).
|
||
|
||
- Issue #19552: venv now supports bootstrapping pip into virtual environments
|
||
|
||
- Issue #17134: Finalize interface to Windows' certificate store. Cert and
|
||
CRL enumeration are now two functions. enum_certificates() also returns
|
||
purpose flags as set of OIDs.
|
||
|
||
- Issue #19555: Restore sysconfig.get_config_var('SO'), (and the distutils
|
||
equivalent) with a DeprecationWarning pointing people at $EXT_SUFFIX.
|
||
|
||
- Issue #8813: Add SSLContext.verify_flags to change the verification flags
|
||
of the context in order to enable certification revocation list (CRL)
|
||
checks or strict X509 rules.

|
||
was introduced by Issue #18379.

||
to load CA certificates and CRL from memory. It supports PEM and DER
|
||
encoded strings.

|
||
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').
|
||
|
||
- Issue #19449: in csv's writerow, handle non-string keys when generating the
|
||
error message that certain keys are not in the 'fieldnames' list.
|
||
|

|
||
|
||
- Issue #19378: Renamed the "dis.Bytecode.display_code" method to
|
||
"dis.Bytecode.dis" and converted it to returning a string rather than
|
||
printing output.
|
||
|
||
- Issue #19378: the "line_offset" parameter in the new "dis.get_instructions"
|
||
API has been renamed to "first_line" (and the default value and usage
|
||
changed accordingly). This should reduce confusion with the more common use
|
||
of "offset" in the dis docs to refer to bytecode offsets.
|

installed for 64-bit/32-bit universal builds. The obsolete and
|
||
undocumented pythonw* symlinks are no longer installed anywhere.
|
||
|
||
- Issue #19553: PEP 453 - "make install" and "make altinstall" now install or

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
|
||
C files to generate argument parsing code. (See PEP 436.)
|
||
|
||
- Issue #18810: Shift stat calls in importlib.machinery.FileFinder such that
|
||
the code is optimistic that if something exists in a directory named exactly
|
||
like the possible package being searched for that it's in actuality a
|
||
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.
|
||
|
||
- Issue #4555: All exported C symbols are now prefixed with either
|
||
"Py" or "_Py".
|
||
|
||
- Issue #19219: Speed up marshal.loads(), and make pyc files slightly
|
||
(5% to 10%) smaller.
|
||
|
||
- Issue #19221: Upgrade Unicode database to version 6.3.0.
|
||
|
||
- Issue #16742: The result of the C callback PyOS_ReadlineFunctionPointer must
|
||
now be a string allocated by PyMem_RawMalloc() or PyMem_RawRealloc() (or NULL
|
||
if an error occurred), instead of a string allocated by PyMem_Malloc() or
|
||
PyMem_Realloc().
|
||
|
||
- Issue #19199: Remove ``PyThreadState.tick_counter`` field
|
||
|
||
- Fix macro expansion of _PyErr_OCCURRED(), and make sure to use it in at
|
||
least one place so as to avoid regressions.
|
||
|
||
- Issue #19087: Improve bytearray allocation in order to allow cheap popping
|
||
of data at the front (slice deletion).
|
||
|
||
- Issue #19014: memoryview.cast() is now allowed on zero-length views.
|
||
|
||
- Issue #18690: memoryview is now automatically registered with
|
||
collections.abc.Sequence
|
||
|
||
- Issue #19078: memoryview now correctly supports the reversed builtin
|
||

|
||
|
||
- Issue #19262: Initial check in of the 'asyncio' package (a.k.a. Tulip,

|
||
|

|
||
and groups() methods of match object now always return a string or a bytes
|
||
object.
|
||
|
||
- Issue #18725: The textwrap module now supports truncating multiline text.
|
||
|
||
- Issue #18776: atexit callbacks now display their full traceback when they

|
||
speed up interpreter start.

|
||
longer shadows the print function.

|
||
often.

|
||
|
||
- Issue #18716: Deprecate the formatter module.
|
||
|
||
- Issue #10712: 2to3 has a new "asserts" fixer that replaces deprecated names

|
||
|
||
- Issue #17839: base64.decodebytes and base64.encodebytes now accept any

||
when necessary. Patch by Oscar Benjamin.
|
||
|
||
- Issue #5845: In site.py, only load readline history from ~/.python_history
|
||
if no history has been read already. This avoids double writes to the
|
||
history file at shutdown.

||
|
||
- Properly initialize all fields of a SSL object after allocation.

1. ppc arch detection for extension module builds broke with Xcode 5
|
||
2. ppc arch detection in configure did not work on OS X 10.4
|
||
3. -sysroot and -arch flags were unnecessarily duplicated
|
||
4. there was no obvious way to configure an intel-32 only build.
|
||
|
||
- Issue #19019: Change the OS X installer build script to use CFLAGS instead
|
||
of OPT for special build options. By setting OPT, some compiler-specific
|
||
options like -fwrapv were overridden and thus not used, which could result
|
||
in broken interpreters when building with clang.

|
||
integer (as in Python 2). Au_read and Au_write now correctly works with file

|
||
|
||
- Issue #18571: Implementation of the PEP 446: file descriptors and file
|
||
handles are now created non-inheritable; add functions
|
||
os.get/set_inheritable(), os.get/set_handle_inheritable() and
|
||
socket.socket.get/set_inheritable().
|
||
|
||
- Issue #11619: The parser and the import machinery do not encode Unicode
|
||
filenames anymore on Windows.
|
||
|
||

|
||
|
||
- Issue #18774: Remove last bits of GNU PTH thread code and thread_pth.h.
|
||
|

of hash collisions. The core idea is to inspect a second key/hash pair
|
||
for each cache line retrieved.
|
||
|
||
- Issue #16105: When a signal handler fails to write to the file descriptor
|
||
registered with ``signal.set_wakeup_fd()``, report an exception instead
|
||
of ignoring the error.
|
||
|
||
- Issue #18722: Remove uses of the "register" keyword in C code.

|
||
fail.
|
||
|
||
- Issue #17934: Add a clear() method to frame objects, to help clean up

||
expensive details (local variables) and break reference cycles.
|
||
|
||
- Issue #18780: %-formatting codes %d, %i, and %u now treat int-subclasses
|
||
as int (displays value of int-subclass instead of str(int-subclass) ).

|
||
Library
|
||
-------
|
||
|
||
- Issue #18808: Thread.join() now waits for the underlying thread state to

be destroyed before returning. This prevents unpredictable aborts in
|
||
Py_EndInterpreter() when some non-daemon threads are still running.

||
|
||

|
||
|
||

|
||
Patch by Claudiu Popa.

|
||
properly handled as unsigned.
|
||
|
||
- Issue #18807: ``pyvenv`` now takes a --copies argument allowing copies
|
||
instead of symlinks even where symlinks are available and the default.
|

|
||
|
||
- Issue #18532: Change the builtin hash algorithms' names to lower case names
|
||
as promised by hashlib's documentation.

||
|
||
- Issue #18405: Improve the entropy of crypt.mksalt().
|
||
|
||
- Issue #12015: The tempfile module now uses a suffix of 8 random characters
|
||
instead of 6, to reduce the risk of filename collision. The entropy was
|
||
reduced when uppercase letters were removed from the charset used to generate
|
||
random characters.
|
||
|
||
- Issue #18585: Add :func:`textwrap.shorten` to collapse and truncate a
|
||
piece of text to a given length.

|
||
|
||

if methods have annotations; it now correctly displays the annotations.
|
||
|
||

|
||
and as_bytes and __bytes__ methods to Message.
|
||

|
||
|
||

|
||
|
||
- Issue #18849: Fixed a Windows-specific tempfile bug where collision with an
|
||
existing directory caused mkstemp and related APIs to fail instead of
|
||
retrying. Report and fix by Vlad Shcherbina.
|
||
|
||
- Issue #18920: argparse's default destination for the version action (-v,
|
||
--version) has also been changed to stdout, to match the Python executable.

test.support. Patch by Valerie Lambert.
|

|
||
- Issue #15507: test_subprocess's test_send_signal could fail if the test
|
||
runner were run in an environment where the process inherited an ignore
|
||
setting for SIGINT. Restore the SIGINT handler to the desired
|
||
KeyboardInterrupt raising one during that test.
|
||
|
||
- Issue #16799: Switched from getopt to argparse style in regrtest's argument
|
||
parsing. Added more tests for regrtest's argument parsing.
|
||
|
||
- Issue #18792: Use "127.0.0.1" or "::1" instead of "localhost" as much as
|
||
possible, since "localhost" goes through a DNS lookup under recent Windows
|
||
versions.

|
||
shipped in OS X 10.6 and later releases.

|
