869 This prevents user-created self-referencing ordered dictionaries from
870 becoming permanently uncollectable GC garbage. The downside is that

872 GC collection rather than freeing memory immediately when the refcnt drops
873 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001332- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1333 start byte and the continuation byte(s) are now considered invalid, instead
1334 of the number of bytes specified by the start byte.
1335 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1336 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1337 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001346- Issue #8748: Fix two issues with comparisons between complex and integer
1347 objects. (1) The comparison could incorrectly return True in some cases
1348 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1349 (2) The comparison raised an OverflowError for large integers, leading
1350 to unpredictable exceptions when combining integers and complex objects
1351 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001353- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00001490- Issue #1533: Fix inconsistency in range function argument processing: any
1491 non-float non-integer argument is now converted to an integer (if possible)
1492 using its __int__ method. Previously, only small arguments were treated this
1493 way; larger arguments (those whose __int__ was outside the range of a C long)
1494 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00001502 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00001503 benefit compared to the dynamic memory allocation fallback. Patch by
1504 Charles-François Natali.

1529 messages when accessing undefined class attributes because of the cheap
1530 inheritance with the underlying socket object. The cheap inheritance has been
1531 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00001532

Georg Brandlfee0f442010-05-22 21:26:21 +00001544- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1545 operation raises multiple signals and more than one of those signals is
1546 trapped, the specification determines the order in which the signals should be
1547 handled. In many cases this order wasn't being followed, leading to the wrong
1548 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00001549

1716-----------------
1717
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001718- Issue #7301: Add environment variable $PYTHONWARNINGS.
1719
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001720- Issue #8329: Don't return the same lists from select.select when no fds are
1721 changed.
1722
Georg Brandlfee0f442010-05-22 21:26:21 +00001723- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001724 on 64-bit machines. The shift count for either left or right shift is
1725 permitted to be up to sys.maxsize.
1726
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001727- Ensure that tokenization of identifiers is not affected by locale.
1728
Georg Brandlfee0f442010-05-22 21:26:21 +00001729- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001730
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001731- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1732
Georg Brandlfee0f442010-05-22 21:26:21 +00001733- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1734 with a non-empty format string. This is an effort to future-proof user
1735 code. If a derived class does not currently implement __format__ but later
1736 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001737 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001738 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001739
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001740- Issue #8268: Old-style classes (not just instances) now support weak
1741 references.
1742
Georg Brandlfee0f442010-05-22 21:26:21 +00001743- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
1744 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00001745
Victor Stinnerc7790ed2010-03-22 12:36:28 +00001746- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00001747
Benjamin Peterson96545892010-03-21 20:21:00 +00001748- Issue #6474: Make error message from passing an inadequate number of keyword
1749 arguments to a function correct.
1750
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001751- Issue #8164: Don't allow lambda functions to have a docstring.
1752
Victor Stinner66644262010-03-10 22:30:19 +00001753- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001754 (SIGINT). If an error occurs while importing the site module, the error is
1755 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001756 module.
1757
Collin Winter001a3952010-03-18 21:54:01 +00001758- Code objects now support weak references.

1761-------
1762
R. David Murray661303f2010-04-13 20:57:40 +00001763- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
1764
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001765- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001766 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1767 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00001769- Issue #8310: Allow dis to examine new style classes.
1770
Georg Brandlfee0f442010-05-22 21:26:21 +00001771- Issue #8257: The Decimal construct now accepts a float instance directly,
1772 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001773
1774 >>> Decimal(1.1)
1775 Decimal('1.100000000000000088817841970012523233890533447265625')
1776
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001777- collections.Counter() now supports a subtract() method.
1778
Georg Brandlfee0f442010-05-22 21:26:21 +00001779- The functools module now has a total_ordering() class decorator to simplify
1780 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001781
Georg Brandlfee0f442010-05-22 21:26:21 +00001782- The functools module also adds cmp_to_key() as a tool to transition old-style
1783 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001784
Georg Brandlfee0f442010-05-22 21:26:21 +00001785- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1786 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001787
Georg Brandlfee0f442010-05-22 21:26:21 +00001788- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1789 InvalidOperation instead of returning False. (Comparisons involving a quiet
1790 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1791 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001792
Georg Brandlfee0f442010-05-22 21:26:21 +00001793- Issue #2531: Comparison operations between floats and Decimal instances now
1794 return a result based on the numeric values of the operands; previously they
1795 returned an arbitrary result based on the relative ordering of id(float) and
1796 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001797
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001798- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001799 argument `-` which tells it to read files to compile from stdin. Each line is
1800 read on demand and the named file is compiled immediately. (Original patch by
1801 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001802
Georg Brandlfee0f442010-05-22 21:26:21 +00001803- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1804 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001806- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1807 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001808 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001809
Georg Brandlfee0f442010-05-22 21:26:21 +00001810- Comparisons using one of <, <=, >, >= between a complex instance and a
1811 Fractions instance now raise TypeError instead of returning True/False. This
1812 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1813 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001814

1823
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001824- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001825 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1826 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001827
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001828- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1829 deprecated.
1830
Georg Brandlfee0f442010-05-22 21:26:21 +00001831- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1832 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001833

1838 existing at the same time, causing a Unicode error when configuration code
1839 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001840

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001868- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001869 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1870 log file to compute the next rollover time. If the log file does not exist,
1871 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001872

Georg Brandlba83f822010-03-14 09:50:54 +00001881- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1882 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1883 This is a behavior change, so email's minor version number is now bumped, to
1884 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001912- Issue #8300: When passing a non-integer argument to struct.pack with any
1913 integer format code, struct.pack first attempts to convert the non-integer
1914 using its __index__ method. If that method is non-existent or raises
1915 TypeError it goes on to try the __int__ method, as described below.
1916
Georg Brandlba83f822010-03-14 09:50:54 +00001917- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1918 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1919 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001920 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1921 inconsistent: __int__ was used for some integer codes but not for others, and
1922 the set of integer codes for which it was used differed between native packing
1923 and standard packing.)

2327Core and Builtins
2328-----------------
2329
Georg Brandlba83f822010-03-14 09:50:54 +00002330- The ``__complex__()`` method is now looked up on the class of instances to
2331 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002333- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

2335
Mark Dickinson1b34d252010-01-01 17:27:30 +00002336- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002337 DeprecationWarning when passed a float argument where an integer was expected.
2338 These functions and methods now raise TypeError instead. The majority of the
2339 effects of this change are in the extension modules, but some core functions
2340 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2341 and many unicode/str methods.

2355 of integers: the result of a/b is now correctly rounded for ints a and b (at
2356 least on IEEE 754 platforms), and in particular does not depend on the
2357 internal representation of a long.

2365
Georg Brandlba83f822010-03-14 09:50:54 +00002366 These executables now work properly with the arch(1) command: ``arch -ppc
2367 python`` will start a universal binary version of python in PPC mode (unlike

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002509

2511 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00002524- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2525 decimal string that's guaranteed to round back to x under correct rounding
2526 (with round-half-to-even rounding mode). Previously it gave a string based on
2527 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2528 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2529 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002530
Georg Brandlba83f822010-03-14 09:50:54 +00002531- Issue #7117: On almost all platforms: float-to-string and string-to-float
2532 conversions within Python are now correctly rounded. Places these conversions
2533 occur include: str for floats and complex numbers; the float and complex
2534 constructors; old-style and new-style numeric formatting; serialization and
2535 deserialization of floats and complex numbers using marshal, pickle and json;
2536 parsing of float and imaginary literals in Python code; Decimal-to-float
2537 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002538
Georg Brandlba83f822010-03-14 09:50:54 +00002539 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2540 providing correctly-rounded strtod and dtoa C functions. This code is
2541 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2542 the C compiler. There may be a small number of platforms on which correct
2543 operation of this code cannot be guaranteed, so the code is not used: notably,
2544 this applies to platforms where the C double format is not IEEE 754 binary64,
2545 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2546 and Python's configure script is unable to determine how to change the FPU
2547 precision. On these platforms conversions use the platform strtod and dtoa,
2548 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002550- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2551 uses the correctly-rounded string <-> float conversions described above (when
2552 available), and so produces correctly rounded results that will display nicely
2553 under the float repr. There are two related small changes: (1) round now
2554 accepts any class with an ``__index__()`` method for its second argument (but
2555 no longer accepts floats for the second argument), and (2) an excessively
2556 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2557 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002699
Georg Brandlba83f822010-03-14 09:50:54 +00002700 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2701 (2) parsing of strings representing infinities and nans was locale aware; and
2702 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00002703
Georg Brandlba83f822010-03-14 09:50:54 +00002704- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2705 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2706 but with at least one decimal point and with a default precision
2707 of 12. Previously, the behavior the same but with a default precision of 6.
2708 This more closely matches ``str()``, and reduces surprises when adding
2709 alignment flags to the empty presentation type. This also affects the new
2710 complex.__format__ in the same way.
2711
2712- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2713 classtype's, even if it was None. property now inserts the __doc__ into the
2714 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00002775 untrackable objects are not tracked by the garbage collector. This can reduce

2784 internal representation of integers, for performance reasons. Base 2**30 is
2785 enabled by default on 64-bit machines. Add --enable-big-digits option to
2786 configure, which overrides the default. Add sys.long_info structseq to

Georg Brandlba83f822010-03-14 09:50:54 +00002888- Issue #4597: Fixed exception handling when the __exit__ function of a context
2889 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00002890
Georg Brandlba83f822010-03-14 09:50:54 +00002891- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00002892
Georg Brandlba83f822010-03-14 09:50:54 +00002893- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2894 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2895 instances. On a typical machine this saves 3 bytes of memory (on average) per
2896 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00002897
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002898- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2899 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2900 instead of throwing a MemoryError.
2901
Georg Brandlba83f822010-03-14 09:50:54 +00002902- Issue #3689: The list reversed iterator now supports __length_hint__ instead
2903 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00002904
Benjamin Petersonc078f922008-11-21 22:27:24 +00002905- Issue #4367: Python would segfault during compiling when the unicodedata
2906 module couldn't be imported and \N escapes were present.
2907
Georg Brandlba83f822010-03-14 09:50:54 +00002908- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2909 file objects with closefd=False. The file descriptor is still kept open but
2910 the file object behaves like a closed file. The ``FileIO`` object also got a
2911 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00002912
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002913- Issue #4348: Some bytearray methods returned that didn't cause any change to
2914 the bytearray, returned the same bytearray instead of a copy.
2915
Georg Brandlba83f822010-03-14 09:50:54 +00002916- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00002917
Benjamin Peterson273c2332008-11-17 22:39:09 +00002918- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
2919
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00002920- Issue #4048: The parser module now correctly validates relative imports.
2921
Benjamin Petersondcee09d2008-10-31 02:16:05 +00002922- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
2923 exec statement.
2924
Georg Brandlba83f822010-03-14 09:50:54 +00002925- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
2926 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00002927
Benjamin Petersonbdca9422008-10-26 20:21:13 +00002928- Issue #4209: Enabling unicode_literals and the print_function in the same
2929 __future__ import didn't work.
2930
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002931- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002932 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002933
Georg Brandlba83f822010-03-14 09:50:54 +00002934- On windows, ``os.chdir()`` given unicode was not working if
2935 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2936 this code path is really executed because I cannot move to such directory on
2937 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002938
Georg Brandlba83f822010-03-14 09:50:54 +00002939- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2940 element is temporarily replaced with an equivalent frozenset. But the
2941 eventual KeyError would always report the empty ``frozenset()`` as the missing
2942 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00002943
Georg Brandlba83f822010-03-14 09:50:54 +00002944- Issue #4509: Various issues surrounding resize of bytearray objects to which
2945 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00002946
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00002947- Issue #4748: Lambda generators no longer return a value.
2948
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00002949- Issue #3582: Use native TLS functions on Windows
2950
Gregory P. Smithae91d092009-03-02 05:13:57 +00002951- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
2952
Georg Brandlba83f822010-03-14 09:50:54 +00002953- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
2954 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00002955
Matthias Klose91a3b9e2009-04-05 21:19:13 +00002956- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2957 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00002958
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00002959- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
2960 returned them on 64bit platforms.
2961
Walter Dörwalded960ac2009-05-03 22:36:33 +00002962- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2963 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2964 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2965 of using the replace error handler in PyUnicode_DecodeUTF8().
2966
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002967- Issue #3739: The unicode-internal encoder now reports the number of characters
2968 consumed like any other encoder (instead of the number of bytes).
2969
Georg Brandlba83f822010-03-14 09:50:54 +00002970- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2971 allocator will be automatically disabled when running under Valgrind. This
2972 gives improved memory leak detection when running under Valgrind, while taking
2973 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00002998- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
2999 ownership when the group is not forced, because the group may be different
3000 from the user's group and inherit from its container when the test is run.

Georg Brandlba83f822010-03-14 09:50:54 +00003042- Issue #6816: runpy now provides a run_path function that allows Python code to
3043 execute file paths that refer to source or compiled Python files as well as
3044 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00003045 __main__.py file. This allows applications that run other Python scripts to
3046 support the same flexibility as the CPython command line itself.
3047
Georg Brandlba83f822010-03-14 09:50:54 +00003048- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
3049 connection with another process, rather than looping endlessly. The default
3050 timeout is 20 seconds, which should be amply sufficient for local connections.

Antoine Pitrouaec41242009-11-02 11:34:27 +00003067 a modification is done through it. This fixes inconsistencies and test

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004338- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4339
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004340- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4341 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4342 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4343 ``printf`` function, whereas PyString_FromFormat has an independent
4344 implementation and uses "%zd" on all platforms for size_t values.
4345 This makes a difference on win64, where ``printf`` needs "%Id" to display
4346 64bit values.
4347
Benjamin Peterson97179b02008-09-09 20:55:01 +00004348- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4352 object; previously an int would be returned for small values. the __long__
4353 method is allowed to return either an int or a long, but the behaviour of
4354 float objects should not change to respect backward compatibility.
4355
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004356- Issue #3751: str.rpartition would perform a left-partition when called with
4357 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004362 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004363 was correctly parsed but parsing of subsequent arguments failed.
4364
Vinay Sajip35e3b032008-09-01 14:33:59 +00004365- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004366 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4367 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4368 when given a tuple of classes as second argument, were looking up
4369 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4370 type object.
4371
Neal Norwitz18aa3882008-08-24 05:04:52 +00004372- Fix crashes on memory allocation failure found with failmalloc.
4373
4374- Fix memory leaks found with valgrind and update suppressions file.
4375
4376- Fix compiler warnings in opt mode which would lead to invalid memory reads.

4416
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004417- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004441 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4442 for catch_warnings() also led to an improvement in the raising of a

4515-----------------
4516
Guido van Rossumf8402962008-08-20 15:01:50 +00004517- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4518 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4519 extensions do not automatically benefit from the class attribute
4520 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4521 to their tp_flags field if they care. This is a backwards
4522 compatibility feature; in 3.0, all types will use the cache by
4523 default.
4524
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004525- Keyword arguments can now follow starred arguments. (``f(a, *args,
4526 keyword=23)`` is now valid syntax.)
4527
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004528- ctypes function pointers that are COM methods have a boolean True
4529 value again.
4530
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004531- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4532 by denying s# to parse objects that have a releasebuffer procedure,
4533 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00004535- Issue #3537: Fix an assertion failure when an empty but presized dict
4536 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00004538- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4539 ValueError consistently across platforms.
4540
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004541- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4542 (64bit Unix, for example), unichr() would truncate its argument and return
4543 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4544
Neal Norwitze7d8be82008-07-31 17:17:14 +00004545- Apply security patches from Apple.
4546
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004547- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00004550- Issue #1819: function calls with several named parameters are now on
4551 average 35% faster (as measured by pybench).
4552
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004553- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4554 the python debugger steps into a class statement: the free variables (local
4555 variables defined in an outer scope) would be deleted from the outer scope.
4556
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004557- Issue #2620: Overflow checking when allocating or reallocating memory
4558 was not always being done properly in some python types and extension
4559 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4560 all been updated to perform better checks and places in the code that
4561 would previously leak memory on the error path when such an allocation
4562 failed have been fixed.

4568
Benjamin Petersone977ad42008-08-20 01:42:01 +00004569- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4570 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4571
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004572- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4573 version reported by these tools does not necessarily follow the python
4574 version numbering scheme, so the module is less strict when parsing it.
4575
Nick Coghlanf70385a2008-08-18 12:42:46 +00004576- Issue #2235: Added Py3k warnings for types which will become unhashable
4577 under the stricter __hash__ inheritance rules in 3.0. Several types
4578 which did not meet the rules for hash invariants and were already
4579 unhashable in 3.0 have now been explicitly flagged as unhashable in
4580 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4581 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4582
Brett Cannon88f801d2008-08-18 00:46:22 +00004583- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4584 imported into the module but exposed as part of the module's API.
4585

4609 regular expression.
4610
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004611- Issue #3476: binary buffered reading through the new "io" library is now
4612 thread-safe.
4613
Brett Cannonbf3157b2008-08-14 05:00:03 +00004614- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4615 since mimetools itself is deprecated. Because modules are cached, all
4616 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4617
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004618- Issue #3134: shutil referenced undefined WindowsError symbol.

4621 menu entries were not deleted.
4622
Brett Cannon83e81842008-08-09 23:30:55 +00004623- Copied the implementation of reduce() to _functools.reduce() to have a

4625
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004626- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4627 a MemoryError rather than silently stop the iteration.
4628
Guido van Rossum59ce9012008-08-09 14:55:34 +00004629- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4630 to _sre.compile() will now be rejected. This should not affect anybody
4631 since the re.compile() function never generates invalid re-bytecode.
4632
Skip Montanaroa032bf42008-08-08 22:52:51 +00004633- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4634 upon first access it can be automatically initialized from the csv file if
4635 it wasn't initialized during instantiation.
4636
Brett Cannon3aa2a492008-08-06 22:28:09 +00004637- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4638 the reload() built-in has been removed.
4639
Brett Cannon7e30b672008-08-04 21:52:25 +00004640- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004641 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4649 raised an AttributeError.
4650
Benjamin Peterson01a24322008-07-28 23:35:27 +00004651- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004652 asking for a specific length. This problem only affected files opened
4653 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004678- Issue #3394: zipfile.writestr sets external attributes when passed a
4679 file name rather than a ZipInfo instance, so files are extracted with
4680 mode 0600 rather than 000 under Unix.
4681
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004682- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4683 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004694- Issue #2235: the C API function PyObject_HashNotImplemented and its
4695 interaction with the tp_hash slot (added in 2.6b2) are now documented
4696
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004697- Issue #643841: The language reference now provides more detailed
4698 coverage of the lookup process for special methods. The disclaimers
4699 regarding lack of coverage of new-style classes have also been
4700 removed, since the coverage is now fairly reasonable.

4704================================
4705
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004706*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004708Core and Builtins
4709-----------------
4710
Georg Brandl3e483f62008-07-16 22:57:41 +00004711- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4712 its methods now allow for items objects that can be converted to
4713 an integer using operator.index().
4714
Mark Dickinson64b7e502008-07-16 09:40:03 +00004715- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4716 produced a ValueError instead of giving the correct float.
4717
Eric Smitha5fa5a22008-07-16 00:11:49 +00004718- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4719 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4720
Mark Dickinson7103aa42008-07-15 19:08:33 +00004721- Issue #3008: the float type has a new instance method 'float.hex'
4722 and a new class method 'float.fromhex' to convert floating-point
4723 numbers to and from hexadecimal strings, respectively.
4724
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004725- Issue #2235: __hash__ is once again inherited by default. To allow
4726 collections.Hashable to remain meaningful in the presence of the
4727 default hash implementation (object.__hash__), it is now possible
4728 to explicit block inheritance of hash by setting __hash__=None at
4729 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4730 level.
4731
Nick Coghlanb028f502008-07-13 14:52:36 +00004732- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4733 the parent module cannot be found while performing an absolute import.
4734 This means that an incorrectly defined __package__ attribute will
4735 now only prevent relative imports in that module rather than causing
4736 all imports from that module to fail.
4737
Nick Coghlan14ff9942008-07-08 14:21:42 +00004738- Issue #2517: Allow unicode messages in Exceptions again by correctly
4739 bypassing the instance dictionary when looking up __unicode__ on
4740 new-style classes.
4741
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004742- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4743 set to a custom object whose write() method happens to install
4744 another file in sys.stdout.
4745
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004746- Issue #3088: Corrected a race condition in classes derived from
4747 threading.local: the first member set by a thread could be saved in
4748 another thread's dictionary.
4749
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004750- Issue #3004: Minor change to slice.indices(): the start and stop
4751 arguments are now treated identically, making the behaviour easier
4752 to describe and understand. For example, slice(None, -10,
4753 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4754 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4755 10, -1).
4756
Georg Brandl278fc502008-07-19 12:46:12 +00004757- Issue #3219: Calling a function with repeated keyword arguments,
4758 f(a=2, a=23), would not cause a syntax error. This was a regression
4759 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004760
Georg Brandl278fc502008-07-19 12:46:12 +00004761- Issue #2862: Make int and float freelist management consistent with
4762 other freelists. Changes their CompactFreeList apis into
4763 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004764

4766-------
4767
Thomas Heller57adf222008-08-14 19:10:48 +00004768- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4769 api functions without holding the GIL, which could lead to a fatal
4770 error when they failed.
4771
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004772- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004780- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4781 ForkingPickler.register() to resolve conflict with ctypes.
4782
Vinay Sajip51e65192008-07-18 09:01:10 +00004783- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004784
Thomas Heller880f5292008-07-15 19:39:38 +00004785- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4786 a valid dlerror() message.
4787
Thomas Heller2bad6572008-07-15 17:19:50 +00004788- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4789 incomplete structure was created.
4790

4794
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004795- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004796
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004797- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4798 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004799 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004800 content-length. The problem had been corrected in the 2.4 branch, but never
4801 merged into trunk.
4802
Georg Brandle78fbcc2008-07-05 10:13:36 +00004803- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00004813- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004814 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004815
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004816- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4817 handling is now the same as that of other special attributes like __name__).
4818
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004819- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4820 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00005209 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005210
5211 This is controlled by the configure argument ``--with-universal-archs``:
5212
5213 - ``--with-universal-archs=all``: install 4-way universal
5214
5215 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5216
5217 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5218
5219 This option should be used in combination with ``--enable-universalsdk=``.
5220
5221 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 +00005271- Issue #1631171: Re-implement the 'warnings' module in C (the
5272 original Python code has been kept as backup). This will allow for
5273 using the 'warning's machinery in such places as the parser where
5274 use of pure Python code is not possible. Both the ``showarning()``
5275 and ``formatwarning()`` gain an optional 'line' argument which is
5276 not called by default for backwards-compatibility reasons. Setting
5277 ``warnings.showwarning()`` to an implementation that lacks support
5278 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005341- Issue #2550: The approach used by client/server code for obtaining
5342 ports to listen on in network-oriented tests has been refined in an
5343 effort to facilitate running multiple instances of the entire
5344 regression test suite in parallel without issue.
5345 test_support.bind_port() has been fixed such that it will always
5346 return a unique port -- which wasn't always the case with the
5347 previous implementation, especially if socket options had been set
5348 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5349 new implementation of bind_port() will actually raise an exception
5350 if it is passed an AF_INET/SOCK_STREAM socket with either the
5351 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5352 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5353 the socket it's been passed. This currently only applies to
5354 Windows. This option prevents any other sockets from binding to the
5355 host/port we've bound to, thus removing the possibility of the
5356 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5357 when a second SOCK_STREAM socket binds and accepts to a host/port
5358 that's already been bound by another socket. The optional preferred
5359 port parameter to bind_port() has been removed. Under no
5360 circumstances should tests be hard coding ports!
5361
5362 test_support.find_unused_port() has also been introduced, which will
5363 pass a temporary socket object to bind_port() in order to obtain an
5364 unused port. The temporary socket object is then closed and
5365 deleted, and the port is returned. This method should only be used
5366 for obtaining an unused port in order to pass to an external program
5367 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5368 a parameter to a server-oriented class that doesn't give you direct
5369 access to the underlying socket used.
5370
5371 Finally, test_support.HOST has been introduced, which should be used
5372 for the host argument of any relevant socket calls (i.e. bind and
5373 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005374
5375 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005376 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005377 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5378 test_asynchat and test_socket_ssl.
5379
Georg Brandl3ee81df2008-05-17 18:14:43 +00005380 It is now possible for multiple instances of the regression test
5381 suite to run in parallel without issue.

5648-----------------
5649
Fred Drakea8ee94b2008-03-01 02:45:07 +00005650- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005651 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005652
Georg Brandlad61bc82008-02-23 15:11:18 +00005653- Issue #2067: file.__exit__() now calls subclasses' close() method.
5654
5655- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005656
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005657- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005658 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005659
Eric Smitha73fbe72008-02-23 03:09:44 +00005660- Added the future_builtins module, which contains hex() and oct().
5661 These are the PEP 3127 version of these functions, designed to be
5662 compatible with the hex() and oct() builtins from Python 3.0. They
5663 differ slightly in their output formats from the existing, unchanged
5664 Python 2.6 builtins. The expected usage of the future_builtins
5665 module is:
5666 from future_builtins import hex, oct
5667
Eric Smith7ef40bf2008-02-20 23:34:22 +00005668- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5669 exponents for exponents with absolute value < 100. Follows C99
5670 standard. This is a change on Windows, which would use 3 digits.
5671 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5672 so that any alterations it does to the resulting string will be
5673 available in stringlib/formatter.h (for float.__format__).
5674
Eric Smith5a3c1352008-02-19 13:21:56 +00005675- Implemented PEP 3101, Advanced String Formatting. This adds a new
5676 builtin format(); a format() method for str and unicode; a
5677 __format__() method to object, str, unicode, int, long, float, and
5678 datetime; the class string.Formatter; and the C API
5679 PyObject_Format().
5680
Georg Brandl3ee81df2008-05-17 18:14:43 +00005681- Fixed several potential crashes, all caused by specially crafted
5682 __del__ methods exploiting objects in temporarily inconsistent
5683 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005684
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005685- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005686 prevent a possible crash: an Abstract Base Class would try to access
5687 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005688
Georg Brandl3ee81df2008-05-17 18:14:43 +00005689- Fixed repr() and str() of complex numbers with infinity or nan as
5690 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005691
Georg Brandl3ee81df2008-05-17 18:14:43 +00005692- Clear all free lists during a gc.collect() of the highest generation
5693 in order to allow pymalloc to free more arenas. Python may give back
5694 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005695
Georg Brandl3ee81df2008-05-17 18:14:43 +00005696- Issue #2045: Fix an infinite recursion triggered when printing a
5697 subclass of collections.defaultdict, if its default_factory is set
5698 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005699
Christian Heimesf75dbef2008-02-08 00:11:31 +00005700- Fixed a minor memory leak in dictobject.c. The content of the free
5701 list was not freed on interpreter shutdown.
5702
Georg Brandl21e99f42010-03-07 15:23:59 +00005703- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005704 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005705
Georg Brandl3ee81df2008-05-17 18:14:43 +00005706- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5707 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005708 to compact the internal free lists of pre-allocted ints and floats.
5709
Georg Brandl3ee81df2008-05-17 18:14:43 +00005710- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5711 calls. Python expected the return type int but the fork familie
5712 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005713
Georg Brandl3ee81df2008-05-17 18:14:43 +00005714- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5715 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005716
Georg Brandl3ee81df2008-05-17 18:14:43 +00005717- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5718 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005719
Georg Brandl3ee81df2008-05-17 18:14:43 +00005720- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5721 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005722
Georg Brandl3ee81df2008-05-17 18:14:43 +00005723- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5724 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005725
Georg Brandl3ee81df2008-05-17 18:14:43 +00005726- Patch #1473257: generator objects gain a gi_code attribute. This is
5727 the same object as the func_code attribute of the function that
5728 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005729
Georg Brandl3ee81df2008-05-17 18:14:43 +00005730- Issue #1920: "while 0" statements were completely removed by the
5731 compiler, even in the presence of an "else" clause, which is
5732 supposed to be run when the condition is false. Now the compiler
5733 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005734
Guido van Rossumeead05f2008-01-24 18:21:02 +00005735- A few crashers fixed: weakref_in_del.py (issue #1377858);
5736 loosing_dict_ref.py (issue #1303614, test67.py);
5737 borrowed_ref_[34].py (not in tracker).
5738
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005739- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005740 suppressed while an extension is loaded by calling SetErrorMode in
5741 dynload_win.c. The error is still reported properly.
5742
Georg Brandl3ee81df2008-05-17 18:14:43 +00005743- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005744 several extension methods and modules do not work without unicode
5745 support.
5746
Georg Brandl26543b12008-01-21 18:36:51 +00005747- Issue #1882: when compiling code from a string, encoding cookies in the
5748 second line of code were not always recognized correctly.
5749
Georg Brandl14404b62008-01-19 19:27:05 +00005750- Issue #1679: "0x" was taken as a valid integer literal.
5751
Georg Brandl6caad7d2008-01-26 14:19:22 +00005752- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005753 added.
5754
Christian Heimesc94e2b52008-01-14 04:13:37 +00005755- sys.float_info / PyFloat_GetInfo: The floating point information
5756 object was converted from a dict to a specialized structseq object.
5757
Georg Brandl3ee81df2008-05-17 18:14:43 +00005758- Patch #1816: Added sys.flags structseq. It exposes the status of
5759 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005760
Georg Brandl3ee81df2008-05-17 18:14:43 +00005761- Objects/structseq.c: Implemented new structseq representation. The
5762 patch makes structseqs (e.g. the return value of os.stat) more
5763 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005764
Georg Brandl3ee81df2008-05-17 18:14:43 +00005765- Patch #1700288: added a type attribute cache that caches method
5766 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005767
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005768- Bug #1776: __import__() no longer accepts filenames on any platform.
5769 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005770
Georg Brandlaed6c662008-01-07 17:25:53 +00005771- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5772
Georg Brandl3ee81df2008-05-17 18:14:43 +00005773- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5774 envvar and sys.dont_write_bytecode attribute. All these can be set
5775 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005776
Georg Brandl3ee81df2008-05-17 18:14:43 +00005777- Improve some exception messages when Windows fails to load an
5778 extension module. Now we get for example '%1 is not a valid Win32
5779 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005780
Georg Brandl3ee81df2008-05-17 18:14:43 +00005781- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005783- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5784 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005785
Christian Heimes0a8143f2007-12-18 23:22:54 +00005786- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005787 and INF. float("nan"), float("inf") and float("-inf") now work on
5788 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005789
Georg Brandl3ee81df2008-05-17 18:14:43 +00005790- Compiler now generates simpler and faster code for dictionary
5791 literals. The oparg for BUILD_MAP now indicates an estimated
5792 dictionary size. There is a new opcode, STORE_MAP, for adding
5793 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005794
Georg Brandl3ee81df2008-05-17 18:14:43 +00005795- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005800- Issue #1538: Avoid copying string in split/rsplit if the split char
5801 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005802
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005803- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005804 SystemError.
5805
Nick Coghlanef01d822007-12-03 12:55:17 +00005806- PEP 366: Allow explicit relative imports when executing modules
5807 inside packages with the -m switch via a new module level
5808 __package__ attribute.
5809
Georg Brandl3ee81df2008-05-17 18:14:43 +00005810- Issue #1402: Fix a crash on exit, when another thread is still
5811 running, and if the deallocation of its frames somehow calls the
5812 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005813

5823 file can now be directly executed by passing their name to the
5824 interpreter. The directory/zipfile is automatically inserted as the
5825 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005826
Georg Brandl3ee81df2008-05-17 18:14:43 +00005827- Issue #1265: Fix a problem with sys.settrace, if the tracing
5828 function uses a generator expression when at the same time the
5829 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005830
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005831- sets and frozensets now have an isdisjoint() method.
5832
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005833- optimize the performance of builtin.sum().
5834
Neal Norwitz44f326e2007-10-05 05:29:17 +00005835- Fix warnings found by the new version of the Coverity checker.
5836
Georg Brandl21e99f42010-03-07 15:23:59 +00005837- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005838 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5839 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005840
Georg Brandl3ee81df2008-05-17 18:14:43 +00005841- Issue #1686386: Tuple's tp_repr did not take into account the
5842 possibility of having a self-referential tuple, which is possible
5843 from C code. Nor did object's tp_str consider that a type's tp_str
5844 could do something that could lead to an inifinite recursion.
5845 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5846 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005847
Georg Brandl3ee81df2008-05-17 18:14:43 +00005848- Issue #1164: It was possible to trigger deadlock when using the
5849 'print' statement to write to a file since the GIL was not released
5850 as needed. Now PyObject_Print() does the right thing along with
5851 various tp_print implementations of the built-in types and those in
5852 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005853
Georg Brandl3ee81df2008-05-17 18:14:43 +00005854- Issue #1147: Exceptions were directly allowing string exceptions in
5855 their throw() method even though string exceptions no longer
5856 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005857

Brett Cannon1e534b52007-09-07 04:18:30 +00005861- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005862 PyObject_Call() never calling back out to Python code to trigger
5863 recursion depth updates/checks. Required the creation of a static
5864 RuntimeError instance in case normalizing an exception put the
5865 recursion check value past its limit. Fixes crashers
5866 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005867

Neal Norwitz0ac60192007-05-27 04:08:54 +00005881- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005882 __*__ attributes. (Some already existed, e.g., __doc__ and
5883 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005884
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005885- Add -3 option to the interpreter to warn about features that are

5889 calls.
5890
Collin Winter62903052007-05-18 23:11:24 +00005891- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005892 "except E as target:". This is to provide forwards compatibility
5893 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005894
Brett Cannon229cee22007-05-05 01:34:02 +00005895- Deprecate BaseException.message as per PEP 352.
5896
Georg Brandl3ee81df2008-05-17 18:14:43 +00005897- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005898 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005899
Vinay Sajip8549ce32007-05-06 17:53:37 +00005900- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005901 setting a plain string, ie don't expand to single letter identifiers.
5902
Raymond Hettinger13936692007-04-11 18:40:58 +00005903- Request #1191699: Slices can now be pickled.
5904
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005905- Request #1193128: str.translate() now allows a None argument for
5906 translations that only remove characters without re-mapping the
5907 remaining characters.
5908
Georg Brandl5cb76c12007-03-21 09:00:39 +00005909- Patch #1682205: a TypeError while unpacking an iterable is no longer
5910 masked by a generic one with the message "unpack non-sequence".

5913
Guido van Rossum143b5642007-03-23 04:58:42 +00005914- Bug #1683368: The object.__init__() and object.__new__() methods are
5915 now stricter in rejecting excess arguments. The only time when
5916 either allows excess arguments is when it is not overridden and the
5917 other one is. For backwards compatibility, when both are
5918 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005919 warning later). Also, type.__init__() insists on the same signature
5920 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005921
Georg Brandl3ee81df2008-05-17 18:14:43 +00005922- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5923 object to complex using its __complex__() method before falling back
5924 to the __float__() method. Therefore, the functions in the cmath
5925 module now can operate on objects that define a __complex__()
5926 method.

5930 same slot names.

5943
Georg Brandl7b9c5552007-03-12 14:30:05 +00005944- Bug #1678647: write a newline after printing an exception in any
5945 case, even when converting the value to a string failed.
5946
Georg Brandl871f1bc2007-03-12 13:17:36 +00005947- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005948 its argument, if it exists. If not, it will work like before. This
5949 allows customizing the output of dir() in the presence of a
5950 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005951
Collin Winter276887b2007-03-12 16:11:39 +00005952- Patch #922167: Python no longer segfaults when faced with infinitely
5953 self-recursive reload() calls (as reported by bug #742342).
5954

5959 parthensized forms. This means complex(repr(x)) now works instead of
5960 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005961
Georg Brandlaa2321b2007-03-07 00:40:28 +00005962- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005963 makes the filenames the warning module prints much more sensible
5964 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005965

Georg Brandl0fca97a2007-03-05 22:28:08 +00005977- Patch #1674228: when assigning a slice (old-style), check for the
5978 sq_ass_slice instead of the sq_slice slot.
5979
Georg Brandl3ee81df2008-05-17 18:14:43 +00005980- When printing an unraisable error, don't print exceptions. before
5981 the name. This duplicates the behavior whening normally printing
5982 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006515 AttributeError instead of an IOError when the server's response

6607 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006892- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6893 with RFC 3207 and forgets any knowledge obtained from the server not
6894 obtained from the TLS negotiation itself. Patch contributed by Bill
6895 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006896
Georg Brandl3ee81df2008-05-17 18:14:43 +00006897- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006898 that the SMTP.starttls() caller no longer needs to call ehlo()
6899 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006900 does not claim to support starttls. Adds the
6901 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6982 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6983 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007000 time so that opening a database previously created with the DB_DUP
7001 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7002 opens. Specifically: dictionary assignment to a DB object will
7003 replace all values for a given key when the database allows
7004 duplicate values. DB users should use DB.put(k, v) when they want
7005 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007006

7012 characters with ASCII value less than 32. Also, it correctly quotes
7013 dots only if they occur on a single line, as opposed to the previous
7014 behavior of quoting dots if they are the second character of any
7015 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007345- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7346 to ``PyTuple_SetItem``, it can be used to populate a brand new
7347 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007348
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007349- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007351- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7352 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7353 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007354
7355- Patch #1720595: add T_BOOL to the range of structmember types.
7356
7357- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7358 ``PyFloat_GetInfo()`` to the float API.
7359
Georg Brandl3ee81df2008-05-17 18:14:43 +00007360- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7361 of w# format code incorrectly truncated the length to an int, even
7362 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7363 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007364
Georg Brandl3ee81df2008-05-17 18:14:43 +00007365- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7366 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007367
Georg Brandl3ee81df2008-05-17 18:14:43 +00007368- PEP 3123: Provide forward compatibility with Python 3.0, while
7369 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7370 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007371
Georg Brandl3ee81df2008-05-17 18:14:43 +00007372- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7373 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007374
7375- Patch #1733960: Allow T_LONGLONG to accept ints.
7376
7377- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7378
Christian Heimes000a0742008-01-03 22:16:32 +00007379- Added a new API function ``PyImport_ImportModuleNoBlock``.
7380
Georg Brandl6caad7d2008-01-26 14:19:22 +00007381- Bug #1637022: Prefix AST symbols with _Py_.
7382
7383- Fix some leftovers from the conversion from int to Py_ssize_t
7384 (relevant to strings and sequences of more than 2**31 items).
7385
7386- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7387 outside of pystate.c and should not be necessary.
7388
Georg Brandl3ee81df2008-05-17 18:14:43 +00007389- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7390 absolute imports. In earlier versions they might have used relative
7391 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007392
Georg Brandl3ee81df2008-05-17 18:14:43 +00007393- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7394 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007395
Georg Brandl3ee81df2008-05-17 18:14:43 +00007396- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7397 macro so it can be used as an expression.

7402
Georg Brandl3ee81df2008-05-17 18:14:43 +00007403- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7404 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7405 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7406 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007407
Georg Brandl3ee81df2008-05-17 18:14:43 +00007408- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
7409 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00007419- buildtools now raises a DeprecationWarning.
7420
Georg Brandl3ee81df2008-05-17 18:14:43 +00007421- Removed the macfs module. It had been deprecated since Python 2.5.
7422 This lead to the deprecation of macostools.touched() as it relied
7423 solely on macfs and was a no-op under OS X.
