1000- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1001 and later systems as is currently done for Python 3.x installers.
1002 For 2.7.7 only, we will provide three installers:
1003 the legacy deprecated 10.3+ 32-bit-only format;
1004 the newer 10.5+ 32-bit-only format;
1005 and the unchanged 10.6+ 64-/32-bit format.
1006 Although binary installers will no longer be available from
1007 python.org as of 2.7.8, it will still be possible to build from
1008 source on 10.3.9 and 10.4 systems if necessary.
1009 See Mac/BuildScript/README.txt for more information.

2394 * Since Xcode 4 removes ppc support, extension module builds now
2395 check for ppc compiler support and by default remove ppc and
2396 ppc64 archs when they are not available.
2397 * Extension module builds now revert to using system installed
2398 headers and libs (/usr and /System/Library) if the SDK used
2399 to build the interpreter is not installed or has moved.
2400 * Try to avoid building extension modules with deprecated
2401 and problematic Apple llvm-gcc compiler. If original compiler
2402 is not available, use clang instead by default.

2765
Mark Dickinsondbbed042011-09-19 16:38:08 +01002766- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2767 int.__pow__. These overflow checks were causing int.__pow__ to produce
2768 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002769 compiler optimizing the check away. Also fix similar overflow checks
2770 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2771 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02002782- Issue #12149: Update the method cache after a type's dictionnary gets
2783 cleared by the garbage collector. This fixes a segfault when an instance
2784 and its type get caught in a reference cycle, and the instance's
2785 deallocator calls one of the methods on the type (e.g. when subclassing
2786 IOBase). Diagnosis and patch by Davide Rizzo.
2787
Florent Xiclunaa1f948b2012-01-24 21:05:10 +01002788- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +02002795 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
2796 raw_input() interrupted by CTRL+c.
2797
Łukasz Langa7a153902011-10-18 17:16:00 +02002798- Issue #10860: httplib now correctly handles an empty port after port

Florent Xiclunac2279652012-02-12 14:49:03 +01002839- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002840 has left two versions of customize_compiler, the original in
2841 distutils.sysconfig and another copy in distutils.ccompiler, with some
2842 parts of distutils calling one and others using the other.
2843 Complete the revert back to only having one in distutils.sysconfig as
2844 is the case in 3.x.
2845
Ned Deily0d0ea482012-02-10 12:59:06 +01002846- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2847 Distutils-based packages with C extension modules may fail because
2848 Apple has removed gcc-4.2, the version used to build python.org
2849 64-bit/32-bit Pythons. If the user does not explicitly override
2850 the default C compiler by setting the CC environment variable,
2851 Distutils will now attempt to compile extension modules with clang
2852 if gcc-4.2 is required but not found. Also as a convenience, if
2853 the user does explicitly set CC, substitute its value as the default
2854 compiler in the Distutils LDSHARED configuration variable for OS X.
2855 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2856 SDK, neither of which are available in Xcode 4. This change does not
2857 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003107- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3108 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3109 interpreter process. This could cause failures in non-Distutils subprocesses
3110 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003111 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003112 deployment target only in the environment of each build subprocess. It is
3113 still possible to globally override the default by setting
3114 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3115 greater or equal to the default value, the value with which the interpreter
3116 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04003144- sys.setcheckinterval() now updates the current ticker count as well as
3145 updating the check interval, so if the user decreases the check interval,
3146 the ticker doesn't have to wind down to zero from the old starting point
3147 before the new interval takes effect. And if the user increases the
3148 interval, it makes sure the new limit takes effect right away rather have an
3149 early task switch before recognizing the new interval.

4147 This prevents user-created self-referencing ordered dictionaries from
4148 becoming permanently uncollectable GC garbage. The downside is that
4149 removing __del__ means that the internal doubly-linked list has to wait for
4150 GC collection rather than freeing memory immediately when the refcnt drops
4151 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004609- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4610 start byte and the continuation byte(s) are now considered invalid, instead
4611 of the number of bytes specified by the start byte.
4612 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4613 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4614 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

4624 objects. (1) The comparison could incorrectly return True in some cases
4625 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4626 (2) The comparison raised an OverflowError for large integers, leading

4822 operation raises multiple signals and more than one of those signals is
4823 trapped, the specification determines the order in which the signals should be

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004970 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4971 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4972 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4992Core and Builtins
4993-----------------
4994
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004995- Issue #7301: Add environment variable $PYTHONWARNINGS.
4996
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004997- Issue #8329: Don't return the same lists from select.select when no fds are
4998 changed.
4999
Georg Brandlfee0f442010-05-22 21:26:21 +00005000- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005001 on 64-bit machines. The shift count for either left or right shift is
5002 permitted to be up to sys.maxsize.
5003
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00005004- Ensure that tokenization of identifiers is not affected by locale.
5005
Georg Brandlfee0f442010-05-22 21:26:21 +00005006- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00005007
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00005008- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
5009
Georg Brandlfee0f442010-05-22 21:26:21 +00005010- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5011 with a non-empty format string. This is an effort to future-proof user
5012 code. If a derived class does not currently implement __format__ but later
5013 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005014 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005015 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00005016
Antoine Pitroua57df2c2010-03-31 21:32:15 +00005017- Issue #8268: Old-style classes (not just instances) now support weak

Benjamin Peterson0dee9c12010-03-17 20:41:42 +00005028- Issue #8164: Don't allow lambda functions to have a docstring.
5029
Victor Stinner66644262010-03-10 22:30:19 +00005030- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00005031 (SIGINT). If an error occurs while importing the site module, the error is
5032 printed and Python exits. Initialize the GIL before importing the site

5047
Georg Brandlfee0f442010-05-22 21:26:21 +00005048- Issue #8257: The Decimal construct now accepts a float instance directly,
5049 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005050
5051 >>> Decimal(1.1)
5052 Decimal('1.100000000000000088817841970012523233890533447265625')
5053
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005054- collections.Counter() now supports a subtract() method.
5055
Georg Brandlfee0f442010-05-22 21:26:21 +00005056- The functools module now has a total_ordering() class decorator to simplify
5057 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00005058
Georg Brandlfee0f442010-05-22 21:26:21 +00005059- The functools module also adds cmp_to_key() as a tool to transition old-style
5060 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00005061
Georg Brandlfee0f442010-05-22 21:26:21 +00005062- Issue #8294: The Fraction constructor now accepts Decimal and float instances
5063 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00005064
Georg Brandlfee0f442010-05-22 21:26:21 +00005065- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5066 InvalidOperation instead of returning False. (Comparisons involving a quiet
5067 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5068 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005069
Georg Brandlfee0f442010-05-22 21:26:21 +00005070- Issue #2531: Comparison operations between floats and Decimal instances now
5071 return a result based on the numeric values of the operands; previously they
5072 returned an arbitrary result based on the relative ordering of id(float) and
5073 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005074
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005075- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005076 argument `-` which tells it to read files to compile from stdin. Each line is
5077 read on demand and the named file is compiled immediately. (Original patch by
5078 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005079
Georg Brandlfee0f442010-05-22 21:26:21 +00005080- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00005083- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5084 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005085 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005086
Georg Brandlfee0f442010-05-22 21:26:21 +00005087- Comparisons using one of <, <=, >, >= between a complex instance and a
5088 Fractions instance now raise TypeError instead of returning True/False. This
5089 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5090 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00005091

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005101- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00005102 didn't support chflags() (for example ZFS under FreeBSD). The error is now
5103 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005104
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00005105- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
5106 deprecated.

5199 the set of integer codes for which it was used differed between native packing
5200 and standard packing.)

Antoine Pitroubb445a12010-02-05 17:05:54 +00005431- Issue #5677: Explicitly forbid write operations on read-only file objects,
5432 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00005433 library would return a bogus result; on Solaris, it was possible to crash the
5434 interpreter. Patch by Stefan Krah.

5445 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +00005446
Georg Brandlba83f822010-03-14 09:50:54 +00005447- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
5448 and add the additional members returned in an OSVERSIONINFOEX structure. The
5449 new members are service_pack_major, service_pack_minor, suite_mask, and
5450 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00005451
Georg Brandlba83f822010-03-14 09:50:54 +00005452- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5453 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5454 returning NULL. The macro now returns a statically allocated empty string
5455 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00005456
Antoine Pitrou64672132010-01-13 07:55:48 +00005457- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

Georg Brandlba83f822010-03-14 09:50:54 +00005464 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
5465 strings,
5466 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5467 numeric strings corresponding to subnormal values,
5468 (3) a memory leak for some values large enough to cause overflow, and
5469 (4) a number of flaws that could lead to incorrectly rounded results.
5470
5471- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
5472 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +00005473

5485
R. David Murray63e4fd72010-02-10 22:42:04 +00005486- Issue #7835: shelve should no longer produce mysterious warnings during
5487 interpreter shutdown.
5488
Georg Brandlba83f822010-03-14 09:50:54 +00005489- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
5490 XML processing instructions and comments. These raw characters are allowed
5491 by the XML specification, and are necessary when outputting e.g. PHP code in
5492 a processing instruction. Patch by Neil Muller.
Antoine Pitrou42fb6ab2010-02-09 17:08:05 +00005493
Georg Brandlba83f822010-03-14 09:50:54 +00005494- Issue #7869: logging: Improved diagnostic for format-time errors.

Georg Brandlba83f822010-03-14 09:50:54 +00005498- Issue #7851: logging: Clarification on logging configuration files.
Vinay Sajip0e6e97d2010-02-04 20:23:45 +00005499
Antoine Pitroud840e512010-02-04 20:20:18 +00005500- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00005501 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00005502 Also, raise ValueError rather than TypeError when an unknown TIPC address
5503 type is specified. Patch by Brian Curtin.
5504
Vinay Sajip28c382f2010-02-04 18:48:53 +00005505- logging: Implemented PEP 391.
5506
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005507- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005508 file position when calling `truncate()`. It would previously change the file
5509 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005510 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5511
Georg Brandlba83f822010-03-14 09:50:54 +00005512- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
5513 class used to represent files stored inside an archive. The new
5514 implementation is significantly faster and can be wrapped in a
5515 ``io.BufferedReader`` object for more speedups. It also solves an issue
5516 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
5517 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00005518
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00005519- Issue #7792: Registering non-classes to ABCs raised an obscure error.
5520
Georg Brandlba83f822010-03-14 09:50:54 +00005521- Removed the deprecated functions ``verify()`` and ``vereq()`` from
5522 Lib/test/test_support.py.
Ezio Melotti82230f92010-01-25 12:37:02 +00005523
Georg Brandlba83f822010-03-14 09:50:54 +00005524- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
5525 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00005526
Georg Brandlba83f822010-03-14 09:50:54 +00005527- Issue #7748: Since unicode values are supported for some metadata options in
5528 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5529 encoded string for them. This ensures that the upload and register commands
5530 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +00005531
Georg Brandlba83f822010-03-14 09:50:54 +00005532- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +00005533 headers in multipart/signed MIME parts, which fixes one of the sources of
5534 invalid modifications to such parts by Generator.

5540 values in debug mode. Patch by Victor Stinner.
Antoine Pitrouefdddd32010-01-14 17:25:24 +00005541
Georg Brandlba83f822010-03-14 09:50:54 +00005542- Issue #7703: Add support for the new buffer API to functions of the binascii
5543 module. Backported from py3k by Florent Xicluna, with some additional tests.

5605-----------------
5606
Georg Brandlba83f822010-03-14 09:50:54 +00005607- The ``__complex__()`` method is now looked up on the class of instances to
5608 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005609
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005610- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5611 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5612
Mark Dickinson1b34d252010-01-01 17:27:30 +00005613- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005614 DeprecationWarning when passed a float argument where an integer was expected.
5615 These functions and methods now raise TypeError instead. The majority of the
5616 effects of this change are in the extension modules, but some core functions
5617 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5618 and many unicode/str methods.

5632 of integers: the result of a/b is now correctly rounded for ints a and b (at
5633 least on IEEE 754 platforms), and in particular does not depend on the
5634 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00005641 executables on OSX.
5642
Georg Brandlba83f822010-03-14 09:50:54 +00005643 These executables now work properly with the arch(1) command: ``arch -ppc
5644 python`` will start a universal binary version of python in PPC mode (unlike
5645 previous releases).

5784 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005785
Georg Brandlba83f822010-03-14 09:50:54 +00005786- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5787 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005788

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005799
Georg Brandlba83f822010-03-14 09:50:54 +00005800- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5801 decimal string that's guaranteed to round back to x under correct rounding
5802 (with round-half-to-even rounding mode). Previously it gave a string based on
5803 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5804 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5805 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005806
Georg Brandlba83f822010-03-14 09:50:54 +00005807- Issue #7117: On almost all platforms: float-to-string and string-to-float
5808 conversions within Python are now correctly rounded. Places these conversions
5809 occur include: str for floats and complex numbers; the float and complex
5810 constructors; old-style and new-style numeric formatting; serialization and
5811 deserialization of floats and complex numbers using marshal, pickle and json;
5812 parsing of float and imaginary literals in Python code; Decimal-to-float
5813 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005814
Georg Brandlba83f822010-03-14 09:50:54 +00005815 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5816 providing correctly-rounded strtod and dtoa C functions. This code is
5817 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5818 the C compiler. There may be a small number of platforms on which correct
5819 operation of this code cannot be guaranteed, so the code is not used: notably,
5820 this applies to platforms where the C double format is not IEEE 754 binary64,
5821 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5822 and Python's configure script is unable to determine how to change the FPU
5823 precision. On these platforms conversions use the platform strtod and dtoa,
5824 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005825
Georg Brandlba83f822010-03-14 09:50:54 +00005826- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5827 uses the correctly-rounded string <-> float conversions described above (when
5828 available), and so produces correctly rounded results that will display nicely
5829 under the float repr. There are two related small changes: (1) round now
5830 accepts any class with an ``__index__()`` method for its second argument (but
5831 no longer accepts floats for the second argument), and (2) an excessively
5832 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5833 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005976 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5977 (2) parsing of strings representing infinities and nans was locale aware; and
5978 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00005979
Georg Brandlba83f822010-03-14 09:50:54 +00005980- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5981 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5982 but with at least one decimal point and with a default precision
5983 of 12. Previously, the behavior the same but with a default precision of 6.
5984 This more closely matches ``str()``, and reduces surprises when adding
5985 alignment flags to the empty presentation type. This also affects the new
5986 complex.__format__ in the same way.
5987
5988- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

6183
Georg Brandlba83f822010-03-14 09:50:54 +00006184- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6185 file objects with closefd=False. The file descriptor is still kept open but
6186 the file object behaves like a closed file. The ``FileIO`` object also got a

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00006207- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00006210- On windows, ``os.chdir()`` given unicode was not working if
6211 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6212 this code path is really executed because I cannot move to such directory on
6213 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006215- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6216 element is temporarily replaced with an equivalent frozenset. But the
6217 eventual KeyError would always report the empty ``frozenset()`` as the missing
6218 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00006238- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6239 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6240 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6241 of using the replace error handler in PyUnicode_DecodeUTF8().
6242
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006243- Issue #3739: The unicode-internal encoder now reports the number of characters

6245
Georg Brandlba83f822010-03-14 09:50:54 +00006246- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

6248 gives improved memory leak detection when running under Valgrind, while taking
6249 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00007515- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
7516 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00007517 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
7518 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00007520- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
7521 regression tests in parallel, shortening the total runtime.
7522
Georg Brandlba83f822010-03-14 09:50:54 +00007523- Issue #5354: New test support function import_fresh_module() makes it easy to
7524 import both normal and optimised versions of modules. test_heapq and
7525 test_warnings have been adjusted to use it, tests for other modules with both
7526 C and Python implementations in the stdlib can be adjusted to use it over
7527 time.

Georg Brandlba83f822010-03-14 09:50:54 +00007535- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
7536 should cause a test to be skipped are now done using import_module from test
7537 support, which does the conversion.

7639
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007640- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7641 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7642 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7643 ``printf`` function, whereas PyString_FromFormat has an independent
7644 implementation and uses "%zd" on all platforms for size_t values.
7645 This makes a difference on win64, where ``printf`` needs "%Id" to display
7646 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00007648- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7652 object; previously an int would be returned for small values. the __long__
7653 method is allowed to return either an int or a long, but the behaviour of
7654 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007663 was correctly parsed but parsing of subsequent arguments failed.
7664
Vinay Sajip35e3b032008-09-01 14:33:59 +00007665- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007666 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7667 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7668 when given a tuple of classes as second argument, were looking up
7669 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7670 type object.
7671

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007809What's New in Python 2.6 beta 3?
7810================================
7811
Barry Warsaw07a4a382008-08-21 01:15:08 +00007812*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007813
7814Core and Builtins
7815-----------------
7816
Guido van Rossumf8402962008-08-20 15:01:50 +00007817- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7818 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7819 extensions do not automatically benefit from the class attribute
7820 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7821 to their tp_flags field if they care. This is a backwards
7822 compatibility feature; in 3.0, all types will use the cache by
7823 default.
7824
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007825- Keyword arguments can now follow starred arguments. (``f(a, *args,
7826 keyword=23)`` is now valid syntax.)
7827
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007828- ctypes function pointers that are COM methods have a boolean True
7829 value again.
7830
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007831- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7832 by denying s# to parse objects that have a releasebuffer procedure,
7833 and introducing s*.
7834
Georg Brandl1e13ea92008-08-11 09:07:59 +00007835- Issue #3537: Fix an assertion failure when an empty but presized dict
7836 object was stored in the freelist.
7837
Mark Dickinsonb6467572008-08-04 21:30:09 +00007838- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7839 ValueError consistently across platforms.
7840
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007841- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7842 (64bit Unix, for example), unichr() would truncate its argument and return
7843 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7844
Neal Norwitze7d8be82008-07-31 17:17:14 +00007845- Apply security patches from Apple.
7846
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007847- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7848 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7849
Antoine Pitrou92f82162008-07-25 22:22:08 +00007850- Issue #1819: function calls with several named parameters are now on
7851 average 35% faster (as measured by pybench).
7852
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007853- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7854 the python debugger steps into a class statement: the free variables (local
7855 variables defined in an outer scope) would be deleted from the outer scope.
7856
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007857- Issue #2620: Overflow checking when allocating or reallocating memory
7858 was not always being done properly in some python types and extension
7859 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7860 all been updated to perform better checks and places in the code that
7861 would previously leak memory on the error path when such an allocation
7862 failed have been fixed.
7863
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007864Library
7865-------
7866
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007867- Issue #3612: Added some missing basic types in ctypes.wintypes.
7868
Benjamin Petersone977ad42008-08-20 01:42:01 +00007869- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7870 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7871
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007872- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7873 version reported by these tools does not necessarily follow the python
7874 version numbering scheme, so the module is less strict when parsing it.
7875
Nick Coghlanf70385a2008-08-18 12:42:46 +00007876- Issue #2235: Added Py3k warnings for types which will become unhashable
7877 under the stricter __hash__ inheritance rules in 3.0. Several types
7878 which did not meet the rules for hash invariants and were already
7879 unhashable in 3.0 have now been explicitly flagged as unhashable in
7880 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7881 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7882
Brett Cannon88f801d2008-08-18 00:46:22 +00007883- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7884 imported into the module but exposed as part of the module's API.
7885
Brett Cannon7b96f072008-08-18 00:41:11 +00007886- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7887
Brett Cannon46225e72008-08-18 00:36:52 +00007888- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7889
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007890- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7891
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007892- Issue #3575: Incremental decoder's decode function now takes bytearray
7893 by using 's*' instead of 't#'.
7894
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007895- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007896 fails unicode conversion on 2nd parameter. (windows only)
7897
Georg Brandl222e2082010-08-01 22:27:39 +00007898- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007899 in a redirect.
7900
Brett Cannonabe423e2008-08-16 21:47:07 +00007901- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007902 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007903
Facundo Batistaeb90b782008-08-16 14:44:07 +00007904- Issue #2776: fixed small issue when handling an URL with double slash
7905 after a 302 response in the case of not going through a proxy.
7906
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007907- Issue #2676: in the email package, content-type parsing was hanging on
7908 pathological input because of quadratic or exponential behaviour of a
7909 regular expression.
7910
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007911- Issue #3476: binary buffered reading through the new "io" library is now
7912 thread-safe.
7913
Brett Cannonbf3157b2008-08-14 05:00:03 +00007914- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7915 since mimetools itself is deprecated. Because modules are cached, all
7916 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7917
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007918- Issue #3134: shutil referenced undefined WindowsError symbol.
7919
Robert Schuppenies14646332008-08-10 11:01:53 +00007920- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7921 menu entries were not deleted.
7922
Brett Cannon83e81842008-08-09 23:30:55 +00007923- Copied the implementation of reduce() to _functools.reduce() to have a
7924 version that did not raise a DeprecationWarning under -3.
7925
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007926- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7927 a MemoryError rather than silently stop the iteration.
7928
Guido van Rossum59ce9012008-08-09 14:55:34 +00007929- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7930 to _sre.compile() will now be rejected. This should not affect anybody
7931 since the re.compile() function never generates invalid re-bytecode.
7932
Skip Montanaroa032bf42008-08-08 22:52:51 +00007933- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7934 upon first access it can be automatically initialized from the csv file if
7935 it wasn't initialized during instantiation.
7936
Brett Cannon3aa2a492008-08-06 22:28:09 +00007937- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7938 the reload() built-in has been removed.
7939
Brett Cannon7e30b672008-08-04 21:52:25 +00007940- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007941 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7944 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
7945 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
7946 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007947
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007948- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7949 raised an AttributeError.
7950
Benjamin Peterson01a24322008-07-28 23:35:27 +00007951- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007952 asking for a specific length. This problem only affected files opened
7953 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007954
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007955- Issue #3449: Update decimal module to use most recent specification
7956 (v. 1.68) and tests (v. 2.58) from IBM.
7957
Georg Brandl222e2082010-08-01 22:27:39 +00007958- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007959

7962
Georg Brandlf9efabb2008-07-23 15:16:45 +00007963- Deprecate the "ast" parser function aliases.
7964
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007965- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7966
7967- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7968 invalid arguments.
7969
7970- Issue #3302: Fix several crashes when calling locale's gettext functions
7971 with None arguments.
7972
7973- Issue #3389: Allow resolving dotted names for handlers in logging
7974 configuration files.
7975
7976- Deprecate the sunaudio module for removal in Python 3.0.
7977
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007978- Issue #3394: zipfile.writestr sets external attributes when passed a
7979 file name rather than a ZipInfo instance, so files are extracted with
7980 mode 0600 rather than 000 under Unix.
7981
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007982- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7983 argument in python 2.5, this broke code that subclassed Popen to include its
7984 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007994- Issue #2235: the C API function PyObject_HashNotImplemented and its
7995 interaction with the tp_hash slot (added in 2.6b2) are now documented
7996
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007997- Issue #643841: The language reference now provides more detailed
7998 coverage of the lookup process for special methods. The disclaimers
7999 regarding lack of coverage of new-style classes have also been
8000 removed, since the coverage is now fairly reasonable.

8004================================
8005
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008006*Release date: 17-Jul-2008*

8009-----------------
8010
Georg Brandl3e483f62008-07-16 22:57:41 +00008011- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8012 its methods now allow for items objects that can be converted to
8013 an integer using operator.index().
8014
Mark Dickinson64b7e502008-07-16 09:40:03 +00008015- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8016 produced a ValueError instead of giving the correct float.
8017
Eric Smitha5fa5a22008-07-16 00:11:49 +00008018- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8019 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8020
Mark Dickinson7103aa42008-07-15 19:08:33 +00008021- Issue #3008: the float type has a new instance method 'float.hex'
8022 and a new class method 'float.fromhex' to convert floating-point
8023 numbers to and from hexadecimal strings, respectively.
8024
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008025- Issue #2235: __hash__ is once again inherited by default. To allow
8026 collections.Hashable to remain meaningful in the presence of the
8027 default hash implementation (object.__hash__), it is now possible
8028 to explicit block inheritance of hash by setting __hash__=None at
8029 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8030 level.
8031
Nick Coghlanb028f502008-07-13 14:52:36 +00008032- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8033 the parent module cannot be found while performing an absolute import.
8034 This means that an incorrectly defined __package__ attribute will
8035 now only prevent relative imports in that module rather than causing
8036 all imports from that module to fail.
8037
Nick Coghlan14ff9942008-07-08 14:21:42 +00008038- Issue #2517: Allow unicode messages in Exceptions again by correctly
8039 bypassing the instance dictionary when looking up __unicode__ on
8040 new-style classes.
8041
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008042- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8043 set to a custom object whose write() method happens to install
8044 another file in sys.stdout.
8045
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008046- Issue #3088: Corrected a race condition in classes derived from
8047 threading.local: the first member set by a thread could be saved in
8048 another thread's dictionary.
8049
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008050- Issue #3004: Minor change to slice.indices(): the start and stop
8051 arguments are now treated identically, making the behaviour easier
8052 to describe and understand. For example, slice(None, -10,
8053 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8054 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8055 10, -1).
8056
Georg Brandl278fc502008-07-19 12:46:12 +00008057- Issue #3219: Calling a function with repeated keyword arguments,
8058 f(a=2, a=23), would not cause a syntax error. This was a regression
8059 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00008061- Issue #2862: Make int and float freelist management consistent with
8062 other freelists. Changes their CompactFreeList apis into
8063 ClearFreeList apis and calls them via gc.collect().

8069 api functions without holding the GIL, which could lead to a fatal
8070 error when they failed.
8071
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008072- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

8506 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008507 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008508
8509 This is controlled by the configure argument ``--with-universal-archs``:
8510
8511 - ``--with-universal-archs=all``: install 4-way universal
8512
8513 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8514
8515 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8516
8517 This option should be used in combination with ``--enable-universalsdk=``.
8518
8519 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008568- Issue #1631171: Re-implement the 'warnings' module in C (the
8569 original Python code has been kept as backup). This will allow for
8570 using the 'warning's machinery in such places as the parser where
8571 use of pure Python code is not possible. Both the ``showarning()``
8572 and ``formatwarning()`` gain an optional 'line' argument which is
8573 not called by default for backwards-compatibility reasons. Setting
8574 ``warnings.showwarning()`` to an implementation that lacks support
8575 for the ``line`` argument will raise a DeprecationWarning.

8599
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00008600- The getpass module has been improved on Unix. It now uses /dev/tty
8601 by default and uses stderr instead of stdout. A GetPassWarning is
8602 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008617- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008618 extension modules between 32 and 64 bit platforms. See the distutls

8632 script environment. This supports setup.py scripts that refer to
8633 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008638- Issue #2550: The approach used by client/server code for obtaining
8639 ports to listen on in network-oriented tests has been refined in an
8640 effort to facilitate running multiple instances of the entire
8641 regression test suite in parallel without issue.
8642 test_support.bind_port() has been fixed such that it will always
8643 return a unique port -- which wasn't always the case with the
8644 previous implementation, especially if socket options had been set
8645 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8646 new implementation of bind_port() will actually raise an exception
8647 if it is passed an AF_INET/SOCK_STREAM socket with either the
8648 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8649 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8650 the socket it's been passed. This currently only applies to
8651 Windows. This option prevents any other sockets from binding to the
8652 host/port we've bound to, thus removing the possibility of the
8653 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8654 when a second SOCK_STREAM socket binds and accepts to a host/port
8655 that's already been bound by another socket. The optional preferred
8656 port parameter to bind_port() has been removed. Under no
8657 circumstances should tests be hard coding ports!
8658
8659 test_support.find_unused_port() has also been introduced, which will
8660 pass a temporary socket object to bind_port() in order to obtain an
8661 unused port. The temporary socket object is then closed and
8662 deleted, and the port is returned. This method should only be used
8663 for obtaining an unused port in order to pass to an external program
8664 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8665 a parameter to a server-oriented class that doesn't give you direct
8666 access to the underlying socket used.
8667
8668 Finally, test_support.HOST has been introduced, which should be used
8669 for the host argument of any relevant socket calls (i.e. bind and
8670 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008671
8672 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008673 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008674 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8675 test_asynchat and test_socket_ssl.
8676
Georg Brandl3ee81df2008-05-17 18:14:43 +00008677 It is now possible for multiple instances of the regression test
8678 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008957- Added the future_builtins module, which contains hex() and oct().
8958 These are the PEP 3127 version of these functions, designed to be
8959 compatible with the hex() and oct() builtins from Python 3.0. They
8960 differ slightly in their output formats from the existing, unchanged
8961 Python 2.6 builtins. The expected usage of the future_builtins
8962 module is:
8963 from future_builtins import hex, oct
8964
Eric Smith7ef40bf2008-02-20 23:34:22 +00008965- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8966 exponents for exponents with absolute value < 100. Follows C99
8967 standard. This is a change on Windows, which would use 3 digits.
8968 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8969 so that any alterations it does to the resulting string will be
8970 available in stringlib/formatter.h (for float.__format__).
8971
Eric Smith5a3c1352008-02-19 13:21:56 +00008972- Implemented PEP 3101, Advanced String Formatting. This adds a new
8973 builtin format(); a format() method for str and unicode; a
8974 __format__() method to object, str, unicode, int, long, float, and
8975 datetime; the class string.Formatter; and the C API
8976 PyObject_Format().
8977
Georg Brandl3ee81df2008-05-17 18:14:43 +00008978- Fixed several potential crashes, all caused by specially crafted
8979 __del__ methods exploiting objects in temporarily inconsistent
8980 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00008982- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008983 prevent a possible crash: an Abstract Base Class would try to access
8984 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008985

Georg Brandl3ee81df2008-05-17 18:14:43 +00008989- Clear all free lists during a gc.collect() of the highest generation
8990 in order to allow pymalloc to free more arenas. Python may give back
8991 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008992
Georg Brandl3ee81df2008-05-17 18:14:43 +00008993- Issue #2045: Fix an infinite recursion triggered when printing a
8994 subclass of collections.defaultdict, if its default_factory is set
8995 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008996
Christian Heimesf75dbef2008-02-08 00:11:31 +00008997- Fixed a minor memory leak in dictobject.c. The content of the free
8998 list was not freed on interpreter shutdown.
8999
Georg Brandl21e99f42010-03-07 15:23:59 +00009000- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009001 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009002
Georg Brandl3ee81df2008-05-17 18:14:43 +00009003- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9004 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009005 to compact the internal free lists of pre-allocted ints and floats.
9006
Georg Brandl3ee81df2008-05-17 18:14:43 +00009007- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9008 calls. Python expected the return type int but the fork familie
9009 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009010
Georg Brandl3ee81df2008-05-17 18:14:43 +00009011- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00009023- Patch #1473257: generator objects gain a gi_code attribute. This is
9024 the same object as the func_code attribute of the function that
9025 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009026
Georg Brandl3ee81df2008-05-17 18:14:43 +00009027- Issue #1920: "while 0" statements were completely removed by the
9028 compiler, even in the presence of an "else" clause, which is
9029 supposed to be run when the condition is false. Now the compiler
9030 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009031
Guido van Rossumeead05f2008-01-24 18:21:02 +00009032- A few crashers fixed: weakref_in_del.py (issue #1377858);
9033 loosing_dict_ref.py (issue #1303614, test67.py);
9034 borrowed_ref_[34].py (not in tracker).
9035
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009036- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009037 suppressed while an extension is loaded by calling SetErrorMode in
9038 dynload_win.c. The error is still reported properly.
9039
Georg Brandl3ee81df2008-05-17 18:14:43 +00009040- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009041 several extension methods and modules do not work without unicode
9042 support.
9043
Georg Brandl26543b12008-01-21 18:36:51 +00009044- Issue #1882: when compiling code from a string, encoding cookies in the
9045 second line of code were not always recognized correctly.
9046
Georg Brandl14404b62008-01-19 19:27:05 +00009047- Issue #1679: "0x" was taken as a valid integer literal.
9048
Georg Brandl6caad7d2008-01-26 14:19:22 +00009049- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009050 added.
9051
Christian Heimesc94e2b52008-01-14 04:13:37 +00009052- sys.float_info / PyFloat_GetInfo: The floating point information
9053 object was converted from a dict to a specialized structseq object.
9054
Georg Brandl3ee81df2008-05-17 18:14:43 +00009055- Patch #1816: Added sys.flags structseq. It exposes the status of
9056 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009057
Georg Brandl3ee81df2008-05-17 18:14:43 +00009058- Objects/structseq.c: Implemented new structseq representation. The
9059 patch makes structseqs (e.g. the return value of os.stat) more
9060 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009061
Georg Brandl3ee81df2008-05-17 18:14:43 +00009062- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00009084 and INF. float("nan"), float("inf") and float("-inf") now work on
9085 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009086
Georg Brandl3ee81df2008-05-17 18:14:43 +00009087- Compiler now generates simpler and faster code for dictionary
9088 literals. The oparg for BUILD_MAP now indicates an estimated
9089 dictionary size. There is a new opcode, STORE_MAP, for adding
9090 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00009134- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009135 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9136 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009137
Georg Brandl3ee81df2008-05-17 18:14:43 +00009138- Issue #1686386: Tuple's tp_repr did not take into account the
9139 possibility of having a self-referential tuple, which is possible
9140 from C code. Nor did object's tp_str consider that a type's tp_str
9141 could do something that could lead to an inifinite recursion.
9142 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9143 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009145- Issue #1164: It was possible to trigger deadlock when using the
9146 'print' statement to write to a file since the GIL was not released
9147 as needed. Now PyObject_Print() does the right thing along with
9148 various tp_print implementations of the built-in types and those in
9149 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009150
Georg Brandl3ee81df2008-05-17 18:14:43 +00009151- Issue #1147: Exceptions were directly allowing string exceptions in
9152 their throw() method even though string exceptions no longer
9153 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009154
Georg Brandl3ee81df2008-05-17 18:14:43 +00009155- Issue #1096: Prevent a segfault from getting the repr of a very
9156 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009157
Brett Cannon1e534b52007-09-07 04:18:30 +00009158- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009159 PyObject_Call() never calling back out to Python code to trigger
9160 recursion depth updates/checks. Required the creation of a static
9161 RuntimeError instance in case normalizing an exception put the
9162 recursion check value past its limit. Fixes crashers
9163 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009164

Neal Norwitz0ac60192007-05-27 04:08:54 +00009178- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009179 __*__ attributes. (Some already existed, e.g., __doc__ and
9180 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009181
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009182- Add -3 option to the interpreter to warn about features that are
9183 deprecated and will be changed/removed in Python 3.0.
9184
Georg Brandl2134e752007-05-21 20:34:16 +00009185- Patch #1686487: you can now pass any mapping after '**' in function
9186 calls.
9187
Collin Winter62903052007-05-18 23:11:24 +00009188- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009189 "except E as target:". This is to provide forwards compatibility
9190 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009197- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009198 setting a plain string, ie don't expand to single letter identifiers.
9199
Raymond Hettinger13936692007-04-11 18:40:58 +00009200- Request #1191699: Slices can now be pickled.
9201
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009202- Request #1193128: str.translate() now allows a None argument for
9203 translations that only remove characters without re-mapping the
9204 remaining characters.
9205
Georg Brandl5cb76c12007-03-21 09:00:39 +00009206- Patch #1682205: a TypeError while unpacking an iterable is no longer

9210
Guido van Rossum143b5642007-03-23 04:58:42 +00009211- Bug #1683368: The object.__init__() and object.__new__() methods are
9212 now stricter in rejecting excess arguments. The only time when
9213 either allows excess arguments is when it is not overridden and the
9214 other one is. For backwards compatibility, when both are
9215 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009216 warning later). Also, type.__init__() insists on the same signature
9217 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009218
Georg Brandl3ee81df2008-05-17 18:14:43 +00009219- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9220 object to complex using its __complex__() method before falling back
9221 to the __float__() method. Therefore, the functions in the cmath
9222 module now can operate on objects that define a __complex__()
9223 method.

9234 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00009241- Bug #1678647: write a newline after printing an exception in any
9242 case, even when converting the value to a string failed.
9243
Georg Brandl871f1bc2007-03-12 13:17:36 +00009244- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009245 its argument, if it exists. If not, it will work like before. This
9246 allows customizing the output of dir() in the presence of a
9247 __getattr__().

9256 parthensized forms. This means complex(repr(x)) now works instead of
9257 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009258
Georg Brandlaa2321b2007-03-07 00:40:28 +00009259- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009260 makes the filenames the warning module prints much more sensible
9261 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00009274- Patch #1674228: when assigning a slice (old-style), check for the
9275 sq_ass_slice instead of the sq_slice slot.
9276
Georg Brandl3ee81df2008-05-17 18:14:43 +00009277- When printing an unraisable error, don't print exceptions. before
9278 the name. This duplicates the behavior whening normally printing
9279 exceptions.

10120 partial fix for Bug #1574584.
10121
Georg Brandl3ee81df2008-05-17 18:14:43 +000010122- Fix turtle so that time.sleep is imported for the entire library.

10175 the first chunk fed to the decoder started with a BOM, but was
10176 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010177
Georg Brandl3ee81df2008-05-17 18:14:43 +000010178- The implementation of UnicodeError objects has been simplified
10179 (start and end attributes are now stored directly as Py_ssize_t
10180 members).

10185 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +000010186
Georg Brandl3ee81df2008-05-17 18:14:43 +000010187- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010188 that the SMTP.starttls() caller no longer needs to call ehlo()
10189 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010190 does not claim to support starttls. Adds the
10191 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
10192 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010234- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010235 works as expected. ``mmap.find`` also takes an optional ``end``

10272 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10273 silently miscode subclasses of those types. Now, it raises a
10274 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010275

Georg Brandl3ee81df2008-05-17 18:14:43 +000010290 time so that opening a database previously created with the DB_DUP
10291 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10292 opens. Specifically: dictionary assignment to a DB object will
10293 replace all values for a given key when the database allows
10294 duplicate values. DB users should use DB.put(k, v) when they want
10295 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010296

Georg Brandl3ee81df2008-05-17 18:14:43 +000010301- Patch #1185447: binascii.b2a_qp() now correctly quotes binary
10302 characters with ASCII value less than 32. Also, it correctly quotes
10303 dots only if they occur on a single line, as opposed to the previous
10304 behavior of quoting dots if they are the second character of any
10305 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010306
Georg Brandla47337f2007-03-13 12:34:25 +000010307- Bug #1622896: fix a rare corner case where the bz2 module raised an

10634
Georg Brandl3ee81df2008-05-17 18:14:43 +000010635- Unified naming convention for free lists and their limits. All free
10636 lists in Object/ are named ``free_list``, the counter ``numfree``
10637 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10638 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010639
Georg Brandl3ee81df2008-05-17 18:14:43 +000010640- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10641 to ``PyTuple_SetItem``, it can be used to populate a brand new
10642 frozenset; but it does not steal a reference to the added item.

10651
10652- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10653 ``PyFloat_GetInfo()`` to the float API.
10654
Georg Brandl3ee81df2008-05-17 18:14:43 +000010655- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10656 of w# format code incorrectly truncated the length to an int, even
10657 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10658 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010659
Georg Brandl3ee81df2008-05-17 18:14:43 +000010660- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

10677
10678- Fix some leftovers from the conversion from int to Py_ssize_t
10679 (relevant to strings and sequences of more than 2**31 items).
10680
10681- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10682 outside of pystate.c and should not be necessary.
10683
Georg Brandl3ee81df2008-05-17 18:14:43 +000010684- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10685 absolute imports. In earlier versions they might have used relative
10686 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010687
Georg Brandl3ee81df2008-05-17 18:14:43 +000010688- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10689 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010690
Georg Brandl3ee81df2008-05-17 18:14:43 +000010691- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010697- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10698 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10699 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10700 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010701

Georg Brandl3ee81df2008-05-17 18:14:43 +000010714- Removed the macfs module. It had been deprecated since Python 2.5.
10715 This lead to the deprecation of macostools.touched() as it relied
10716 solely on macfs and was a no-op under OS X.
