| - Issue #15509: `webbrowser.UnixBrowser` no longer passes empty arguments to |
| Popen when ``%action`` substitutions produce empty strings. |
| |
| - 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 |

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

| =============================================== |
| |
| *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 |

| 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 |
| (replaces fixes for Issue #15645). |
| |
| Documentation |
| ------------- |
| |
| - Issue #15814: The memoryview enhancements in 3.3.0 accidentally permitted the |

| - Issue #15778: Ensure that ``str(ImportError(msg))`` returns a str even when |
| msg isn't a str. |
| |
| - Issue #2051: Source file permission bits are once again correctly copied to |
| the cached bytecode file. (The migration to importlib reintroduced this |
| problem because these was no regression test. A test has been added as part of |
| this patch) |
| |
| - Issue #15761: Fix crash when ``PYTHONEXECUTABLE`` is set on Mac OS X. |

| 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. |

| - Issue #15285: Refactor the approach for testing connect timeouts using two |
| external hosts that have been configured specifically for this type of test. |

| - LZMAFile now accepts the modes "rb"/"wb"/"ab" as synonyms of "r"/"w"/"a". |
| |
| - The bz2 and lzma modules now each contain an open() function, allowing |
| compressed files to readily be opened in text mode as well as binary mode. |

| not explicitly asked for. This is no longer an exception as mkdir |
| cannot control if the OS sets that bit for it or not. |

| line. |
| |

| |
| C-API |
| ----- |
| |
| - Issue #13783: Inadvertent additions to the public C API in the PEP 380 |
| implementation have either been removed or marked as private interfaces. |
| |
| Extension Modules |
| ----------------- |
| |
| - Issue #15000: Support the "unique" x32 architecture in _posixsubprocess.c. |
| |
| Documentation |

| 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. |

| 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. |

| 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. |

| 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 |

| 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`` |

| FileIO.open(). |
| |
| - Issue #10519: Avoid unnecessary recursive function calls in |
| setobject.c. |
| |

| |
| - 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 |
| ``__traceback__`` attribute. Patch by Petri Lehtinen. |
| |
| - Issue #13146: Writing a pyc file is now atomic under POSIX. |
| |
| - Issue #7833: Extension modules built using distutils on Windows will no |
| longer include a "manifest" to prevent them failing at import time in some |
| embedded situations. |
| |
| - PEP 3151 / issue #12555: reworking the OS and IO exception hierarchy. |
| |
| - Issue #13560: Add PyUnicode_DecodeLocale(), PyUnicode_DecodeLocaleAndSize() |

| |
| - 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. |
| |
| - PEP 393: flexible string representation. Thanks to Torsten Becker for the |
| initial implementation, and Victor Stinner for various bug fixes. |

| and bytearray.split may now be passed as keyword arguments. |
| |

| 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). |
| |
| - Issue #9200: The str.is* methods now work with strings that contain non-BMP |
| characters even in narrow Unicode builds. |
| |
| - Issue #12791: Break reference cycles early when a generator exits with |
| an exception. |

| titlecased and cased non-letter characters. |
| |

| outside the BMP. |
| |
| - Issue #12575: Validate user-generated AST before it is compiled. |
| |

| return the respective singleton instances. |
| |
| - Forbid summing bytes with sum(). |
| |
| - Verify the types of AST strings and identifiers provided by the user before |
| compiling them. |
| |

| Formerly, bool(None) returned False only because of special case logic |
| in PyObject_IsTrue(). |
| |

| non-exception class. |
| |

| 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. |
| |

| UnicodeEncodeError on recursion limit. |
| |
| - Issue #11187: Remove bootstrap code (use ASCII) of |

| |
| - 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 |
| code pre-dates the ability to subclass extension types. It is now possible |

| underscored names like multiprocessing did. |
| |
| - Issue #9723: Add shlex.quote functions, to escape filenames and command |

| Connection:close header. |
| |
| - Issue #12102: Document that buffered files must be flushed before being used |

| Jacek Konieczny. |
| |
| - Issue #665194: email.utils now has format_datetime and parsedate_to_datetime |

| 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. |
| |
| - Issue #12273: Remove ast.__version__. AST changes can be accounted for by |
| checking sys.version_info or sys._mercurial. |
| |
| - Silence spurious "broken pipe" tracebacks when shutting down a |
| ProcessPoolExecutor. |
| |
| - Fix potential resource leaks in concurrent.futures.ProcessPoolExecutor |
| by joining all queues and processes when shutdown() is called. |
| |

| to make HTTP POST requests, and make sure it uses CRLF. |
| |
| - 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 |
| Python scripts using a encoding different than UTF-8 (read the coding cookie |
| of the script). |
| |
| - Issue #12493: subprocess: Popen.communicate() now also handles EINTR errors |
| if the process has only one pipe. |
| |
| - Issue #12467: warnings: fix a race condition if a warning is emitted at |
| shutdown, if globals()['__file__'] is None. |

| - Issue #12451: pydoc: importfile() now opens the Python script in binary mode, |
| 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 |
| of the text mode (using the locale encoding) to avoid encoding issues. |
| |
| - Issue #12147: Adjust the new-in-3.2 smtplib.send_message method for better |

| |
| - Issue #12352: Fix a deadlock in multiprocessing.Heap when a block is freed by |
| the garbage collector while the Heap lock is held. |
| |
| - Issue #12462: time.sleep() now immediately calls the (Python) signal handler |
| if it is interrupted by a signal, instead of having to wait until the next |
| instruction. |
| |
| - 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. |
| |
| - Issue #12451: pydoc.synopsis() now reads the encoding cookie if available, |
| 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. |
| |
| - Issue #12422: In the copy module, don't store objects that are their own copy |

| - Issue #11637: Fix support for importing packaging setup hooks from the |
| project directory. |
| |
| - Issue #6771: Moved the curses.wrapper function from the single-function |
| wrapper module into __init__, eliminating the module. Since __init__ was |
| already importing the function to curses.wrapper, there is no API change. |
| |
| - Issue #11584: email.header.decode_header no longer fails if the header |
| passed to it is a Header object, and Header/make_header no longer fail |
| if given binary unknown-8bit input. |
| |

| 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 |

| reset, check the version of the OpenSSL headers Python was compiled against, |
| rather than the runtime version of the OpenSSL library. |

| - 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. |
