|
|
|
|
- Issue #12776, issue #11839: Call `argparse` type function (specified by
|
|
add_argument) only once. Before, the type function was called twice in the
|
|
case where the default was specified and the argument was given as well. This
|
|
was especially problematic for the FileType type, as a default file would
|
|
always be opened, even if a file argument was specified on the command line.
|
|
|
|
- Issue #15906: Fix a regression in `argparse` caused by the preceding change,

|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #15882: Change `_decimal` to accept any coefficient tuple when
|

with the specification).
|
|
|
|
- Issue #15925: Fix a regression in `email.util` where the `parsedate()` and

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

|
|
- 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.
|

|
external hosts that have been configured specifically for this type of test.

try to infer the source path from the bytecode path as
|
|
PyImport_ExecCodeModuleWithPathnames() does.

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

|
|
block loading of the gdb hooks

|
|
in contextlib.ExitStack (Initial patch by Alon Horev)
|
|
|
|
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
|
|
(Modules/_freeze_importlib) to build Python/importlib.h.

|
|

|
|
means imp.NullImporter is no longer implicitly used.
|
|
|
|
- Issue #13903: Implement PEP 412. Individual dictionary instances can now share
|
|
their keys with other dictionaries. Classes take advantage of this to share

|
their instance dictionary keys for improved memory and performance.

|
|
found in __builtins__.
|
|
|
|
- Issue #12599: Be more strict in accepting None compared to a false-like
|
|

|
|
|

|
|
making it "atomic" for many purposes. Patch by Filip Gruszczyński.
|
|
|

|
- Issue #10181: New memoryview implementation fixes multiple ownership
|
|
and lifetime issues of dynamically allocated Py_buffer members (#9990)

|
|
(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.

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

|
|
- Issue #13452: PyUnicode_EncodeDecimal() doesn't support error handlers
|
|
different than "strict" anymore. The caller was unable to compute the

|
|
to os.utime, os.lutimes, os.futimes, os.futimens, os.futimesat, in

object identity).
|
|
|
|
- Issue #1294232: In a few cases involving metaclass inheritance, the

class object. These cases now behave correctly. Patch by Daniel Urban.
|
|
|
|
- Issue #12753: Add support for Unicode name aliases and named sequences.

- 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 #13845: On Windows, time.time() now uses GetSystemTimeAsFileTime()

Condition, etc.) used to be factory functions returning instances of hidden

|
|
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.

|
Linux 3.0.
|
|
|

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

|
|
|
|
- Issue #12451: pydoc: html_getfile() now uses tokenize.open() to support

|
|
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,

|
than UTF-8 (scripts using the coding cookie).
|
|
|
|
- Issue #12451: xml.dom.pulldom: parse() now opens files in binary mode instead

|
|
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 read the Python script from the right encoding.

|
|
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.

|
now include some resource-intensive tests, but no longer run the test suite

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

|
|
|

|
error twice anymore if there is only one error.
|
