|
|
number of frames from multichannel stream. Au_write.writeframesraw() now
|

correctly updates current file position. Au_read.getnframes() now returns an
|
|
integer (as in Python 2). Au_read and Au_write now correctly works with file
|

|
|
argument (and therefore is reading the user's $HOME/.netrc file), it now

Library
|

|
|
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
|

|
|
|
|

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 #17158: Add 'symbols' to help() welcome message; clarify
|
|
'modules spam' messages.
|
|
|
|
- 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()`.
|
|
|
|
- Issue #15340: Fix importing the random module when ``/dev/urandom`` cannot be
|
|
opened. This was a regression caused by the hash randomization patch.
|
|
|
|
- Issue #10650: Deprecate the watchexp parameter of the `Decimal.quantize()`
|
|
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.
|
|
|
|

|
formats. The intended restrictions have now been documented - they will be
|
|
correctly enforced in 3.3.1.
|
|
|
|

|
|
test_posix.py to account for this.
|
|

|
|
external hosts that have been configured specifically for this type of test.
|
|
|
|
- Issue #15743: Remove the deprecated method usage in `urllib` tests. Patch by
|
|

|
|
data. Patch by Kushal Das.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Output lib files for PGO build into PGO directory.
|
|
|
|
- Pick up 32-bit launcher from PGO directory on 64-bit PGO build.
|
|
|
|
- Drop ``PC\python_nt.h`` as it's not used. Add input dependency on custom
|
|
build step.
|
|
|
|
- Issue #15511: Drop explicit dependency on pythonxy.lib from _decimal amd64
|
|
configuration.

|
|
|
|
Core and Builtins
|
|
-----------------

|
|
- Fix a (most likely) very rare memory leak when calling main() and not being
|
|
able to decode a command-line argument.
|
|
|
|
- Issue #14815: Use Py_ssize_t instead of long for the object hash, to
|
|
preserve all 64 bits of hash on Win64.
|
|
|
|
- Issue #12268: File readline, readlines and read() or readall() methods
|
|
no longer lose data when an underlying read system call is interrupted.
|
|
IOError is no longer raised due to a read system call returning EINTR
|
|
from within these methods.
|
|
|
|
- Issue #11626: Add _SizeT functions to stable ABI.

|
|
locale.getpreferredencoding(False) instead of locale.getpreferredencoding()
|
|
in text mode if the encoding is not specified. Don't change temporary the
|
|
locale encoding using locale.setlocale(), use the current locale encoding
|
|
instead of the user preferred encoding.
|
|
|

|
|

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
|
|
|
|

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

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.
|
|
|
|

|
|
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
|

|
|
Renaud Blanch, Ryan Kelly, Zbigniew Jędrzejewski-Szmek and Nick Coghlan)
|
|
|
|
- Issue #13748: Raw bytes literals can now be written with the ``rb`` prefix
|

|
|
Patch by sbt.

|
|
objects. Initial patch by Matthias Troffaes.
|
|
|
|

|
|
overriden and take additional arguments (followup to issue #12555).
|
|
|
|

|
|
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.

|
|
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.
|
|
|
|
- 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.

|
|
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

|
|
handling to os.utimensat in order to remove the need for explicit None.
|
|
|
|

|
|
PyUnicode_Format by PyUnicode_FromFormat.
|
|

|
|
|
|
- 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.

warnings. Patch by Josh Triplett and Petri Lehtinen.
|
|
|
|
- Issue #12281: Rewrite the MBCS codec to handle correctly replace and ignore

|
|
error handlers, instead of only replace to encode and ignore to decode.
|

- Issue #12911: Fix memory consumption when calculating the repr() of huge
|
|
tuples or lists.

|
|
|
|
- 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
|
|

|
|
mapped to POSIX errno ENOTDIR (previously EINVAL).

|
|
characters even in narrow Unicode builds.

|
|
deallocator calls one of the methods on the type (e.g. when subclassing
|
|
IOBase). Diagnosis and patch by Davide Rizzo.
|

- 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 #12016: Multibyte CJK decoders now resynchronize faster. They only
|
|
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).
|
|
|

|
|
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
|
|

the garbage collector while the Heap lock is held.
|
|

disk space statistics.

|
|
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
|
|
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.

|
wrapper module into __init__, eliminating the module. Since __init__ was

|
|
- Issue #11584: email.header.decode_header no longer fails if the header

|
|
- Issue #11651: Improve the Makefile test targets to run more of the test suite
|
|
more quickly. The --multiprocess option is now enabled by default, reducing
|
|
the amount of time needed to run the tests. "make test" and "make quicktest"
|
|
now include some resource-intensive tests, but no longer run the test suite
|
|
twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides
|
|
an easy platform-independent way to run test suite with sensible defaults.
|
|
|
|
- Issue #12331: The test suite for the packaging module can now run from an
|
|
installed Python.
|
|
|
|
- Issue #12331: The test suite for lib2to3 can now run from an installed
|
|
Python.
|
|
|
|
- Issue #12626: In regrtest, allow to filter tests using a glob filter
|
|
with the ``-m`` (or ``--match``) option. This works with all test cases
|
|
using the unittest module. This is useful with long test suites
|
|
such as test_io or test_subprocess.
|
|
|
|
- Issue #12624: It is now possible to fail after the first failure when
|
|
running in verbose mode (``-v`` or ``-W``), by using the ``--failfast``
|
|
(or ``-G``) option to regrtest. This is useful with long test suites
|
|
such as test_io or test_subprocess.
|
|
|
|

|
as the processor type on some Mac systems.
|
|
|
|

|
|
failure in name resolution.
|
|
|
|
- Issue #11812: Solve transient socket failure to connect to 'localhost'
|
|
in test_telnetlib.py.
|
|
|
|
- Solved a potential deadlock in test_telnetlib.py. Related to issue #11812.
|
|
|
|
- Avoid failing in test_robotparser when mueblesmoraleda.com is flaky and
|
|
an overzealous DNS service (e.g. OpenDNS) redirects to a placeholder
|
|
Web site.
|
|
|
|
- Avoid failing in test_urllibnet.test_bad_address when some overzealous
|
|
DNS service (e.g. OpenDNS) resolves a non-existent domain name. The test
|
|
is now skipped instead.
|
|
|
|
- Issue #12440: When testing whether some bits in SSLContext.options can be
|
|
reset, check the version of the OpenSSL headers Python was compiled against,
|
|
rather than the runtime version of the OpenSSL library.
|
|
|
|
- Issue #11512: Add a test suite for the cgitb module. Patch by Robbie Clemons.
|
|
|
|
- Issue #12497: Install test/data to prevent failures of the various codecmaps
|
|
tests.

|
|
testcase failure in test_ssl.
|
|
|

|
|
test in a fresh process with only one thread and to not change signal
|
|
handling of the parent process.
|
|
|
|
- Issue #8716: Avoid crashes caused by Aqua Tk on OSX when attempting to run
|
|
test_tk or test_ttk_guionly under a username that is not currently logged
|
|
in to the console windowserver (as may be the case under buildbot or ssh).
|
|
|
|
- Issue #12407: Explicitly skip test_capi.EmbeddingTest under Windows.
|
|
|
|
- Issue #12400: regrtest -W doesn't rerun the tests twice anymore, but captures
|
|
the output and displays it on failure instead. regrtest -v doesn't print the
|
|
error twice anymore if there is only one error.
|
|
|
|
- Issue #12141: Install copies of template C module file so that
|
|
test_build_ext of test_distutils and test_command_build_ext of
|
|
test_packaging are no longer silently skipped when
|
|
run outside of a build directory.
|
|
|
|

|
|
Patch by Garrett Cooper.

|
test_rlock_acquire_interruption() of test_threadsignals if a thread lock is
|
|
implemented using a POSIX mutex and a POSIX condition variable. A POSIX
|
|
condition variable cannot be interrupted by a signal (e.g. on Linux, the

C-API
|
|
-----
|
|
|
|
- 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.

|
|
- Issue #13560: Add PyUnicode_DecodeLocale(), PyUnicode_DecodeLocaleAndSize()
|
|
and PyUnicode_EncodeLocale() functions to the C API to decode/encode from/to
