|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #15882: Change `_decimal` to accept any coefficient tuple when
|
|
constructing infinities. This is done for backwards compatibility with

decimal.py: Infinity coefficients are undefined in _decimal (in accordance
|
|
with the specification).
|
|
|
|
- Issue #15925: Fix a regression in `email.util` where the `parsedate()` and
|
|
`parsedate_tz()` functions did not return None anymore when the argument could

What's New in Python 3.3.0 Release Candidate 2?
|
|
===============================================
|
|
|
|
*Release date: 09-Sep-2012*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #13992: The trashcan mechanism is now thread-safe. This eliminates
|
|
sporadic crashes in multi-thread programs when several long deallocator chains
|
|
ran concurrently and involved subclasses of built-in container types.
|
|
|
|
- Issue #15784: Modify `OSError`.__str__() to better distinguish between errno
|
|
error numbers and Windows error numbers.
|
|
|
|
- Issue #15781: Fix two small race conditions in import's module locking.
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #15847: Fix a regression in argparse, which did not accept tuples as
|
|
argument lists anymore.
|
|
|
|
- Issue #15828: Restore support for C extensions in `imp.load_module()`.
|
|
|

|
|
method.
|
|
|
|
- Issue #15785: Modify `window.get_wch()` API of the curses module: return a
|
|
character for most keys, and an integer for special keys, instead of always
|
|
returning an integer. So it is now possible to distinguish special keys like
|
|
keypad keys.
|
|
|
|
- Issue #14223: Fix `window.addch()` of the curses module for special characters
|
|
like curses.ACS_HLINE: the Python function addch(int) and addch(bytes) is now
|
|
calling the C function waddch()/mvwaddch() (as it was done in Python 3.2),
|
|
instead of wadd_wch()/mvwadd_wch(). The Python function addch(str) is still
|
|
calling the C function wadd_wch()/mvwadd_wch() if the Python curses is linked
|
|
to libncursesw.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Issue #15822: Really ensure 2to3 grammar pickles are properly installed

|
Documentation
|
|
-------------
|
|
|
|
- Issue #15814: The memoryview enhancements in 3.3.0 accidentally permitted the
|
|
hashing of multi-dimensional memorviews and memoryviews with multi-byte item
|
|
formats. The intended restrictions have now been documented - they will be
|
|
correctly enforced in 3.3.1.

|
|
Patch by Chris Rebert.
|
|
|
|
- Create a 'Concurrent Execution' section in the docs, and split up the
|
|
'Optional Operating System Services' section to use a more user-centric
|
|
classification scheme (splitting them across the new CE section, IPC and text
|
|
processing). Operating system limitatons can be reflected with the Sphinx
|
|
``:platform:`` tag, it doesn't make sense as part of the Table of Contents.

|
|
test_posix.py to account for this.

Tests
|
|
-----
|
|
|
|
- Issue #14769: test_capi now has SkipitemTest, which cleverly checks
|
|
for "parity" between PyArg_ParseTuple() and the Python/getargs.c static
|

|
Build
|
|
-----
|
|
|
|
- Issue #13590: Improve support for OS X Xcode 4:
|
|
* Try to avoid building Python or extension modules with problematic
|
|
llvm-gcc compiler.
|
|
* Since Xcode 4 removes ppc support, extension module builds now
|
|
check for ppc compiler support and automatically remove ppc and
|
|
ppc64 archs when not available.
|
|
* Since Xcode 4 no longer install SDKs in default locations,
|
|
extension module builds now revert to using installed headers
|
|
and libs if the SDK used to build the interpreter is not
|
|
available.
|
|
* Update ./configure to use better defaults for universal builds;
|
|
in particular, --enable-universalsdk=yes uses the Xcode default
|
|
SDK and --with-universal-archs now defaults to "intel" if ppc
|
|
not available.
|
|
|
|
- Issue #14225: Fix Unicode support for curses (#12567) on OS X
|
|
|
|
- Issue #14928: Fix importlib bootstrap issues by using a custom executable
|
|

|
|

What's New in Python 3.3.0 Alpha 1?
|
|
===================================
|
|
|
|
*Release date: 05-Mar-2012*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #14172: Fix reference leak when marshalling a buffer-like object
|
|
(other than a bytes object).
|
|
|
|
- Issue #13521: dict.setdefault() now does only one lookup for the given key,
|
|
making it "atomic" for many purposes. Patch by Filip Gruszczyński.
|
|
|
|
- PEP 409, Issue #6210: "raise X from None" is now supported as a means of
|
|
suppressing the display of the chained exception context. The chained
|
|
context still remains available as the __context__ attribute.
|
|
|
|
- Issue #10181: New memoryview implementation fixes multiple ownership
|
|
and lifetime issues of dynamically allocated Py_buffer members (#9990)
|
|
as well as crashes (#8305, #7433). Many new features have been added
|
|
(See whatsnew/3.3), and the documentation has been updated extensively.
|
|
The ndarray test object from _testbuffer.c implements all aspects of
|
|
PEP-3118, so further development towards the complete implementation
|
|
of the PEP can proceed in a test-driven manner.
|
|
|
|
Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review
|
|
and many ideas.
|
|
|
|
- Issue #12834: Fix incorrect results of memoryview.tobytes() for
|
|
non-contiguous arrays.
|
|
|
|
- Issue #5231: Introduce memoryview.cast() method that allows changing
|
|
format and shape without making a copy of the underlying memory.
|
|
|
|
- Issue #14084: Fix a file descriptor leak when importing a module with a
|
|
bad encoding.
|
|
|
|
- Upgrade Unicode data to Unicode 6.1.
|
|
|
|
- Issue #14040: Remove rarely used file name suffixes for C extensions
|
|
(under POSIX mainly).
|
|
|
|
- Issue #14051: Allow arbitrary attributes to be set of classmethod and
|
|
staticmethod.
|
|
|
|
- Issue #13703: oCERT-2011-003: Randomize hashes of str and bytes to protect
|
|
against denial of service attacks due to hash collisions within the dict and
|
|
set types. Patch by David Malcolm, based on work by Victor Stinner.
|
|
|
|
- Issue #13020: Fix a reference leak when allocating a structsequence object
|
|
fails. Patch by Suman Saha.
|
|
|
|
- Issue #13908: Ready types returned from PyType_FromSpec.

|
|
modification time doesn't fit in a 32-bit timestamp.
|
|
|
|
- Issue #12705: A SyntaxError exception is now raised when attempting to
|
|
compile multiple statements as a single interactive statement.
|
|
|
|
- Fix the builtin module initialization code to store the init function for
|
|
future reinitialization.
|
|
|
|
- Issue #8052: The posix subprocess module would take a long time closing
|
|
all possible file descriptors in the child process rather than just open
|
|
file descriptors. It now closes only the open fds if possible for the
|
|
default close_fds=True behavior.
|
|
|
|
- Issue #13629: Renumber the tokens in token.h so that they match the indexes
|
|
into _PyParser_TokenNames.
|
|
|
|
- Issue #13752: Add a casefold() method to str.
|
|
|
|
- Issue #13761: Add a "flush" keyword argument to the print() function,
|
|
used to ensure flushing the output stream.
|
|
|
|
- Issue #13645: pyc files now contain the size of the corresponding source
|
|
code, to avoid timestamp collisions (especially on filesystems with a low
|
|
timestamp resolution) when checking for freshness of the bytecode.
|
|
|
|
- PEP 380, Issue #11682: Add "yield from <x>" to support easy delegation to
|
|
subgenerators (initial patch by Greg Ewing, integration into 3.3 by
|
|
Renaud Blanch, Ryan Kelly, Zbigniew Jędrzejewski-Szmek and Nick Coghlan)
|
|
|
|
- Issue #13748: Raw bytes literals can now be written with the ``rb`` prefix
|
|
as well as ``br``.
|
|
|
|
- Issue #12736: Use full unicode case mappings for upper, lower, and title case.
|
|
|
|
- Issue #12760: Add a create mode to open(). Patch by David Townshend.
|
|

|
|
|
|
- Issue #13577: Built-in methods and functions now have a __qualname__.
|
|
Patch by sbt.
|
|
|
|
- Issue #6695: Full garbage collection runs now clear the freelist of set
|
|
objects. Initial patch by Matthias Troffaes.
|
|
|
|
- Fix OSError.__init__ and OSError.__new__ so that each of them can be
|
|
overriden and take additional arguments (followup to issue #12555).
|
|
|
|
- Fix the fix for issue #12149: it was incorrect, although it had the side
|
|
effect of appearing to resolve the issue. Thanks to Mark Shannon for
|
|
noticing.
|
|
|
|
- Issue #13505: Pickle bytes objects in a way that is compatible with
|
|
Python 2 when using protocols <= 2.
|
|
|
|
- Issue #11147: Fix an unused argument in _Py_ANNOTATE_MEMORY_ORDER. (Fix
|
|
given by Campbell Barton).
|
|
|
|
- Issue #13503: Use a more efficient reduction format for bytearrays with
|
|
pickle protocol >= 3. The old reduction format is kept with older protocols
|
|
in order to allow unpickling under Python 2. Patch by Irmen de Jong.
|
|
|
|
- Issue #7111: Python can now be run without a stdin, stdout or stderr
|
|
stream. It was already the case with Python 2. However, the corresponding
|
|
sys module entries are now set to None (instead of an unusable file object).
|
|
|
|
- Issue #11849: Ensure that free()d memory arenas are really released
|
|
on POSIX systems supporting anonymous memory mappings. Patch by
|
|
Charles-François Natali.
|
|
|
|
- Issue #13452: PyUnicode_EncodeDecimal() doesn't support error handlers
|
|
different than "strict" anymore. The caller was unable to compute the
|
|
size of the output buffer: it depends on the error handler.
|
|
|
|
- PEP 3155 / issue #13448: Qualified name for classes and functions.
|
|
|
|
- Issue #13436: Fix a bogus error message when an AST object was passed
|
|
an invalid integer value.
|
|
|
|
- Issue #13411: memoryview objects are now hashable when the underlying
|
|
object is hashable.
|
|
|
|
- Issue #13338: Handle all enumerations in _Py_ANNOTATE_MEMORY_ORDER
|
|
to allow compiling extension modules with -Wswitch-enum on gcc.
|
|
Initial patch by Floris Bruynooghe.
|
|
|
|
- Issue #10227: Add an allocation cache for a single slice object. Patch by
|
|
Stefan Behnel.
|
|
|
|
- Issue #13393: BufferedReader.read1() now asks the full requested size to
|
|
the raw stream instead of limiting itself to the buffer size.
|
|
|
|
- Issue #13392: Writing a pyc file should now be atomic under Windows as well.
|
|
|
|
- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
|
|
already accepts them).
|
|
|
|
- Issue #13389: Full garbage collection passes now clear the freelists for
|
|
list and dict objects. They already cleared other freelists in the
|
|
interpreter.
|
|
|
|
- Issue #13327: Remove the need for an explicit None as the second argument
|
|
to os.utime, os.lutimes, os.futimes, os.futimens, os.futimesat, in
|
|
order to update to the current time. Also added keyword argument
|
|
handling to os.utimensat in order to remove the need for explicit None.
|
|
|
|
- Issue #13350: Simplify some C code by replacing most usages of
|
|
PyUnicode_Format by PyUnicode_FromFormat.
|
|
|
|
- Issue #13342: input() used to ignore sys.stdin's and sys.stdout's unicode
|
|
error handler in interactive mode (when calling into PyOS_Readline()).
|
|
|
|
- Issue #9896: Add start, stop, and step attributes to range objects.
|
|
|
|
- Issue #13343: Fix a SystemError when a lambda expression uses a global
|
|
variable in the default value of a keyword-only argument: ``lambda *,
|
|
arg=GLOBAL_NAME: None``
|
|
|
|
- Issue #12797: Added custom opener parameter to builtin open() and
|
|
FileIO.open().
|
|
|
|
- Issue #10519: Avoid unnecessary recursive function calls in
|
|
setobject.c.
|
|
|
|
- Issue #10363: Deallocate global locks in Py_Finalize().
|
|
|
|
- Issue #13018: Fix reference leaks in error paths in dictobject.c.
|
|
Patch by Suman Saha.
|
|
|
|
- Issue #13201: Define '==' and '!=' to compare range objects based on
|
|
the sequence of values they define (instead of comparing based on
|
|
object identity).
|
|
|
|
- Issue #1294232: In a few cases involving metaclass inheritance, the
|
|
interpreter would sometimes invoke the wrong metaclass when building a new
|
|
class object. These cases now behave correctly. Patch by Daniel Urban.
|
|
|
|
- Issue #12753: Add support for Unicode name aliases and named sequences.
|
|
Both ``unicodedata.lookup()`` and '\N{...}' now resolve aliases,
|
|
and ``unicodedata.lookup()`` resolves named sequences too.
|
|
|
|
- Issue #12170: The count(), find(), rfind(), index() and rindex() methods
|
|
of bytes and bytearray objects now accept an integer between 0 and 255
|
|
as their first argument. Patch by Petri Lehtinen.
|
|
|
|
- Issue #12604: VTRACE macro expanded to no-op in _sre.c to avoid compiler
|
|
warnings. Patch by Josh Triplett and Petri Lehtinen.
|
|
|
|
- Issue #12281: Rewrite the MBCS codec to handle correctly replace and ignore
|
|
error handlers on all Windows versions. The MBCS codec is now supporting all
|
|
error handlers, instead of only replace to encode and ignore to decode.
|
|
|
|
- Issue #13188: When called without an explicit traceback argument,
|
|
generator.throw() now gets the traceback from the passed exception's
|
|

|
|
|
|
- Issue #13560: Add PyUnicode_DecodeLocale(), PyUnicode_DecodeLocaleAndSize()
|
|
and PyUnicode_EncodeLocale() functions to the C API to decode/encode from/to
|
|
the current locale encoding.
|
|
|
|
- Add internal API for static strings (_Py_identifier et al.).
|
|
|
|
- Issue #13063: the Windows error ERROR_NO_DATA (numbered 232 and described
|
|
as "The pipe is being closed") is now mapped to POSIX errno EPIPE
|
|
(previously EINVAL).
|
|
|
|
- Issue #12911: Fix memory consumption when calculating the repr() of huge
|
|
tuples or lists.
|
|
|
|

|
|
and bytearray.split may now be passed as keyword arguments.
|
|
|
|
- Issue #13012: The 'keepends' parameter to str.splitlines may now be passed
|
|
as a keyword argument: "my_string.splitlines(keepends=True)". The same
|
|
change also applies to bytes.splitlines and bytearray.splitlines.
|
|
|
|
- Issue #7732: Don't open a directory as a file anymore while importing a
|
|
module. Ignore the direcotry if its name matchs the module name (e.g.
|
|
"__init__.py") and raise a ImportError instead.
|
|
|
|
- Issue #13021: Missing decref on an error path. Thanks to Suman Saha for
|
|
finding the bug and providing a patch.
|
|
|
|
- Issue #12973: Fix overflow checks that relied on undefined behaviour in
|
|
list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These bugs
|
|
caused test failures with recent versions of Clang.
|
|
|
|
- Issue #12904: os.utime, os.futimes, os.lutimes, and os.futimesat now write
|
|
atime and mtime with nanosecond precision on modern POSIX platforms.
|
|
|
|
- Issue #12802: the Windows error ERROR_DIRECTORY (numbered 267) is now
|
|
mapped to POSIX errno ENOTDIR (previously EINVAL).

|
|
characters even in narrow Unicode builds.

|
|
an exception.
|
|
|
|

|
|
titlecased and cased non-letter characters.
|
|
|
|
- Issue #12732: In narrow unicode builds, allow Unicode identifiers which fall
|
|
outside the BMP.
|
|
|
|
- Issue #12575: Validate user-generated AST before it is compiled.
|
|
|
|
- Make type(None), type(Ellipsis), and type(NotImplemented) callable. They
|
|
return the respective singleton instances.
|
|

|
- Verify the types of AST strings and identifiers provided by the user before
|
|
compiling them.

|
|
non-exception class.
|
|
|
|
- Issue #12149: Update the method cache after a type's dictionary gets
|
|
cleared by the garbage collector. This fixes a segfault when an instance
|
|
and its type get caught in a reference cycle, and the instance's
|
|
deallocator calls one of the methods on the type (e.g. when subclassing
|
|
IOBase). Diagnosis and patch by Davide Rizzo.
|
|

|
|
we cannot get the locale encoding (if nl_langinfo(CODESET) is not available)
|
|
instead of using UTF-8.
|
|
|
|
- When a generator yields, do not retain the caller's exception state on the
|
|
generator.
|
|
|
|
- Issue #12475: Prevent generators from leaking their exception state into the
|
|
caller's frame as they return for the last time.
|
|
|
|
- Issue #12291: You can now load multiple marshalled objects from a stream,
|
|
with other data interleaved between marshalled objects.
|
|
|

|
|
sequence, which will be converted to a list and sorted by dir().
|
|
|
|
- Issue #12265: Make error messages produced by passing an invalid set of
|
|
arguments to a function more informative.

|
|
mercurial is not installed.
|
|
|
|
- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
|
|
the following case: sys.stdin.read() stopped with CTRL+d (end of file),
|
|
raw_input() interrupted by CTRL+c.
|
|
|
|
- Issue #12216: Allow unexpected EOF errors to happen on any line of the file.
|
|
|
|
- Issue #12199: The TryExcept and TryFinally and AST nodes have been unified
|
|
into a Try node.
|
|
|
|
- Issue #9670: Increase the default stack size for secondary threads on
|
|
Mac OS X and FreeBSD to reduce the chances of a crash instead of a
|
|
"maximum recursion depth" RuntimeError exception.
|
|
(patch by Ronald Oussoren)

stdout mode is binary and the length is greater than 66,000 bytes (or less,
|
|
depending on heap usage).

- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
|
|
Distutils-based packages with C extension modules may fail because
|
|
Apple has removed gcc-4.2, the version used to build python.org
|
|
64-bit/32-bit Pythons. If the user does not explicitly override
|
|
the default C compiler by setting the CC environment variable,
|
|
Distutils will now attempt to compile extension modules with clang
|
|
if gcc-4.2 is required but not found. Also as a convenience, if
|
|
the user does explicitly set CC, substitute its value as the default
|
|
compiler in the Distutils LDSHARED configuration variable for OS X.
|
|
(Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
|
|
SDK, neither of which are available in Xcode 4. This change does not
|
|
attempt to override settings to support their use with Xcode 4.)

- Issue #10968: Remove indirection in threading. The public names (Event,
|
|
Condition, etc.) used to be factory functions returning instances of hidden
|
|
classes (_Event, _Condition, etc.), because (if Guido recalls correctly) this

- Issue #12551: Provide a get_channel_binding() method on SSL sockets so as
|
|
to get channel binding data for the current SSL session (only the
|
|
"tls-unique" channel binding is implemented). This allows the implementation
|
|
of certain authentication mechanisms such as SCRAM-SHA-1-PLUS. Patch by
|
|
Jacek Konieczny.
|
|
|
|
- Issue #665194: email.utils now has format_datetime and parsedate_to_datetime

functions, allowing for round tripping of RFC2822 format dates.

|
|
|
- Issue #12571: Add a plat-linux3 directory mirroring the plat-linux2
|
|
directory, so that "import DLFCN" and other similar imports work on
|
|
Linux 3.0.
|
|
|
|
- Issue #7484: smtplib no longer puts <> around addresses in VRFY and EXPN
|
|
commands; they aren't required and in fact postfix doesn't support that form.

|
|
ignore the first byte of an invalid byte sequence. For example,
|
|
b'\xff\n'.decode('gb2312', 'replace') gives '\ufffd\n' instead of '\ufffd'.
|
|
|
|
- Issue #12459: time.sleep() now raises a ValueError if the sleep length is
|
|
negative, instead of an infinite sleep on Windows or raising an IOError on

|
Linux for example, to have the same behaviour on all platforms.
|
|
|
|
- Issue #12451: pydoc: html_getfile() now uses tokenize.open() to support

|
of the script).
|
|
|
|
- Issue #12493: subprocess: Popen.communicate() now also handles EINTR errors
|
|
if the process has only one pipe.

|
|
instead of text mode using the locale encoding, to avoid encoding issues.
|
|
|
|
- Issue #12451: runpy: run_path() now opens the Python script in binary mode,
|
|
instead of text mode using the locale encoding, to support other encodings
|
|
than UTF-8 (scripts using the coding cookie).
|
|
|
|
- Issue #12451: xml.dom.pulldom: parse() now opens files in binary mode instead
|

|
|
- Issue #12442: new shutil.disk_usage function, providing total, used and free
|
|
disk space statistics.
|
|
|
|
- Issue #12451: The XInclude default loader of xml.etree now decodes files from
|
|
UTF-8 instead of the locale encoding if the encoding is not specified. It now
|
|
also opens XML files for the parser in binary mode instead of the text mode
|
|
to avoid encoding issues.
|
|
|
|
- Issue #12451: doctest.debug_script() doesn't create a temporary file
|
|
anymore to avoid encoding issues.
|
|

|
|
to read the Python script from the right encoding.
|
|
|
|
- Issue #12451: distutils now opens the setup script in binary mode to read the
|
|
encoding cookie, instead of opening it in UTF-8.
|
|
|
|
- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
|
|
check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
|
|
interpreter process. This could cause failures in non-Distutils subprocesses
|
|
and was unreliable since tests or user programs could modify the interpreter
|
|
environment after Distutils set it. Instead, have Distutils set the the
|
|
deployment target only in the environment of each build subprocess. It is
|
|
still possible to globally override the default by setting
|
|
MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
|
|
greater or equal to the default value, the value with which the interpreter
|
|
was built. Also, implement the same handling in packaging.

|
running in verbose mode (``-v`` or ``-W``), by using the ``--failfast``
