What's New in Python 3.5.1 release candidate 1?
|
|
===============================================
|
|
|
|
Release date: TBA
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- 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 #25203: Failed readline.set_completer_delims() no longer left the
|
|
module in inconsistent state.
|
|
|
|
- Issue #23600: Default implementation of tzinfo.fromutc() was returning
|
|
wrong results in some cases.
|
|
|
|
- Issue #23329: Allow the ssl module to be built with older versions of
|
|
LibreSSL.
|
|
|
|
- Prevent overflow in _Unpickler_Read.
|
|
|
|
- Issue #25047: The XML encoding declaration written by Element Tree now
|
|
respects the letter case given by the user. This restores the ability to
|
|
write encoding names in uppercase like "UTF-8", which worked in Python 2.
|
|
|
|
- Issue #25135: Make deque_clear() safer by emptying the deque before clearing.
|
|
This helps avoid possible reentrancy issues.
|
|
|
|
- Issue #19143: platform module now reads Windows version from kernel32.dll to
|
|
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.
|
|
|
|
- Issue #24982: shutil.make_archive() with the "zip" format now adds entries
|
|
for directories (including empty directories) in ZIP file.
|
|
|
|
- Issue #25019: Fixed a crash caused by setting non-string key of expat parser.
|
|
Based on patch by John Leitch.
|
|
|
|
- Issue #16180: Exit pdb if file has syntax error, instead of trapping user
|
|
in an infinite loop. Patch by Xavier de Gaye.
|
|
|
|
- Issue #24891: Fix a race condition at Python startup if the file descriptor
|
|
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.
|
|
|
|
- Issue #24881: Fixed setting binary mode in Python implementation of FileIO
|
|
on Windows and Cygwin. Patch from Akira Li.
|
|

|
|
Patch from Berker Peksag.
|

|
|
metaclasses. Patch by Ethan Furman.

IDLE
|

- Issue #24861: Most of idlelib is private and subject to change.
|
|
Use idleib.idle.* to start Idle. See idlelib.__init__.__doc__.
|
|
|
|
- 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.
|

|
|
|
Documentation
|
|
-------------
|
|
|
|
- Issue #12067: Rewrite Comparisons section in the Expressions chapter of the
|
|
language reference. Some of the details of comparing mixed types were
|
|
incorrect or ambiguous. NotImplemented is only relevant at a lower level
|

|
and default behaviour and consistency suggestions for user-defined classes.

|
arguments of different kinds (UCS1, UCS2, UCS4).
|
|
|

and socket open until the garbage collector cleans them up. Patch by
|
|
Martin Panter.

|
|
now retried when interrupted by a signal not in the *sigset* parameter, if

|
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.

|
|
editor window with a filename. When Class Browser is requested otherwise,
|
|
from a shell, output window, or 'Untitled' editor, Idle no longer displays

|

|
|
|
|
- Issue #4832: Save As to type Python files automatically adds .py to the

|
|
consolidating and improving human-validated tests of Idle. Change other files
|
|
as needed to work with htest. Running the module as __main__ runs all tests.

Build
|
|
-----
|
|
|
|
- Issue #15506: Use standard PKG_PROG_PKG_CONFIG autoconf macro in the configure
|
|
script.
|
|
|
|
- Issue #22935: Allow the ssl module to be compiled if openssl doesn't support
|
|
SSL 3.
|
|
|
|
- Issue #22592: Drop support of the Borland C compiler to build Python. The
|
|
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).
|
|
|
|
- Issue #16537: Check whether self.extensions is empty in setup.py. Patch by
|
|
Jonathan Hosmer.

|
|
|

|
|
Wagner.

|
- Issue #21958: Define HAVE_ROUND when building with Visual Studio 2013 and
|
|
above. Patch by Zachary Turner.
|
|
|
|
- Issue #18093: the programs that embed the CPython runtime are now in a
|
|
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
|
|
root of the source tree, which passes all arguments through to the most
|
|
recently built interpreter.
|
|
|
|
- Issue #21285: Refactor and fix curses configure check to always search
|
|
in a ncursesw directory.
|
|
|
|
- Issue #15234: For BerkelyDB and Sqlite, only add the found library and
|
|
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 later gets any change.
|
|
|
|
- Issue #20644: OS X installer build support for documentation build changes
|
|

|
|
- Issue #20022: Eliminate use of deprecated bundlebuilder in OS X builds.

|
|

|
|
|
|
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.
|
|
|
|
- Issue #22079: PyType_Ready() now checks that statically allocated type has
|
|
no dynamically allocated bases.
|
|
|

- Issue #22453: Removed non-documented macro PyObject_REPR().
|
|
|
|
- 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
|
|
-------------
|
|
|
|

|
- Issue #22394: Doc/Makefile now supports ``make venv PYTHON=../python`` to

``make html PYTHON=venv/bin/python3``.
|
|

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

|
|

|
mention the ability to load the OS certificates.

|
|
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 #19697: Document cases where __main__.__spec__ is None.

|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #20625: Parameter names in __annotations__ were not mangled properly.
|
|
Discovered by Jonas Wielicki, patch by Yury Selivanov.
|
|
|
|
- Issue #20261: In pickle, lookup __getnewargs__ and __getnewargs_ex__ on the
|
|
type of the object.
|
|
|
|
- Issue #20619: Give the AST nodes of keyword-only arguments a column and line
|
|
number.
|
|
|
|
- Issue #20526: Revert changes of issue #19466 which introduces a regression:
|
|
don't clear anymore the state of Python threads early during the Python
|
|
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:
|
|
loop.set_exception_handler(), loop.default_exception_handler(), and
|
|
loop.call_exception_handler().
|
|
|
|
- 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.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Issue #20641: Run MSI custom actions (pip installation, pyc compilation)
|
|
with the NoImpersonate flag, to support elevated execution (UAC).
|
|
|
|
- Issue #20221: Removed conflicting (or circular) hypot definition when
|
|
compiled with VS 2010 or above. Initial patch by Tabrez Mohammed.

|
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 objects 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.
|
|
|
|
- Issue #20394: Silence Coverity warning in audioop module.
|
|

|
|
duplicate arguments. Patch by Glenn Langford.
|
|
|
|
- Issue #8260: The read(), readline() and readlines() methods of
|
|
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
|

Claudiu Popa.
|
|
|
|

|
|
|
|
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.
|
|

- Issue #20246: Fix buffer overflow in socket.recvfrom_into.
|
|
|
|
- Issues #20206 and #5803: Fix edge case in email.quoprimime.encode where it

|
using a more efficient algorithm that doesn't have the bug.
|
|
|
|
- Issue #19082: Working xmlrpc.server and xmlrpc.client examples. Both in
|
|
modules and in documentation. Initial patch contributed by Vajrasky Kok.

|
|
invalid fileobj.
|

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

|
|
- Issue #19719: Make importlib.abc.MetaPathFinder.find_module(),
|
|
PathEntryFinder.find_loader(), and Loader.load_module() use PEP 451 APIs to
|
|
help with backwards-compatibility.
|
|

|
|
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.
|
|
|
|

|
|
__new__ are always of type newfunc, the type of the tp_new slot.

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

|
|
delaying its output or even redirecting it to a separate file.

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
|
|
based systems.
|
|
|
|
- Issue #20097: Fix bad use of "self" in importlib's WindowsRegistryFinder.
|
|
|
|
- Issue #19729: In str.format(), fix recursive expansion in format spec.
|
|
|
|
- Issue #19638: Fix possible crash / undefined behaviour from huge (more than 2
|
|
billion characters) input strings in _Py_dg_strtod.
|
|
|

|
|
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".
|
|
|
|

|
|
shutdown.
|

|
|
_TracebackLogger class.

|
|
- Added a Task.current_task() class method to asyncio.
|

|
|
handler to limit EINTR occurrences.
|
|
|
|
- Implemented write flow control in asyncio for proactor event loop (Windows).
|
|
|
|

|
|
write()/sendto() accept bytearray/memoryview.

|
|
from X.org distribution using makelocalealias.py.

|
|
locale encodings with hyphens.

|
|
level (wrong type).

|
|
quotechar fields. Original patch by Vajrasky Kok.

- 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

|
|
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.
|
|
|
|
- Issue #19944: Fix importlib.find_spec() so it imports parents as needed
|

|
|
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.
|
|
|
|
- Issue #19876: selectors unregister() no longer raises ValueError or OSError
|
|
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.

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".
|
|
|

|
|
|

|
- Issue #19552: venv now supports bootstrapping pip into virtual environments
|

|
|
equivalent) with a DeprecationWarning pointing people at $EXT_SUFFIX.

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.

|
|
longer shadows the print function.
|
|

|
|
often.
|

|
|
|
|

|
|
|
|
- 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.

|
|
|
|
- Issue #14499: Fix several problems with OS X universal build support:
|
|
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.

|
|

|
|
registered with ``signal.set_wakeup_fd()``, report an exception instead

Library
|
|
-------

|
|
shipped in OS X 10.6 and later releases.
