975 the newer 10.5+ 32-bit-only format;
976 and the unchanged 10.6+ 64-/32-bit format.
977 Although binary installers will no longer be available from
978 python.org as of 2.7.8, it will still be possible to build from
979 source on 10.3.9 and 10.4 systems if necessary.

2103 especially problematic for the FileType type, as a default file would always
2104 be opened, even if a file argument was specified on the command line.

2362 32-bit-only installer Pythons on systems with Xcode 4 (currently
2363 OS X 10.8, 10.7, and optionally 10.6).
2364 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2365 * Since Xcode 4 removes ppc support, extension module builds now
2366 check for ppc compiler support and by default remove ppc and
2367 ppc64 archs when they are not available.
2368 * Extension module builds now revert to using system installed
2369 headers and libs (/usr and /System/Library) if the SDK used
2370 to build the interpreter is not installed or has moved.
2371 * Try to avoid building extension modules with deprecated
2372 and problematic Apple llvm-gcc compiler. If original compiler
2373 is not available, use clang instead by default.

2736
Mark Dickinsondbbed042011-09-19 16:38:08 +01002737- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2738 int.__pow__. These overflow checks were causing int.__pow__ to produce
2739 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002740 compiler optimizing the check away. Also fix similar overflow checks
2741 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2742 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02002753- Issue #12149: Update the method cache after a type's dictionnary gets
2754 cleared by the garbage collector. This fixes a segfault when an instance
2755 and its type get caught in a reference cycle, and the instance's
2756 deallocator calls one of the methods on the type (e.g. when subclassing
2757 IOBase). Diagnosis and patch by Davide Rizzo.

Victor Stinner08563d92011-05-30 23:44:13 +02002766 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
2767 raw_input() interrupted by CTRL+c.
2768
Łukasz Langa7a153902011-10-18 17:16:00 +02002769- Issue #10860: httplib now correctly handles an empty port after port

Florent Xiclunac2279652012-02-12 14:49:03 +01002810- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002811 has left two versions of customize_compiler, the original in
2812 distutils.sysconfig and another copy in distutils.ccompiler, with some
2813 parts of distutils calling one and others using the other.

2815 is the case in 3.x.
2816
Ned Deily0d0ea482012-02-10 12:59:06 +01002817- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2818 Distutils-based packages with C extension modules may fail because
2819 Apple has removed gcc-4.2, the version used to build python.org
2820 64-bit/32-bit Pythons. If the user does not explicitly override
2821 the default C compiler by setting the CC environment variable,
2822 Distutils will now attempt to compile extension modules with clang
2823 if gcc-4.2 is required but not found. Also as a convenience, if
2824 the user does explicitly set CC, substitute its value as the default
2825 compiler in the Distutils LDSHARED configuration variable for OS X.
2826 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2827 SDK, neither of which are available in Xcode 4. This change does not
2828 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003078- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3079 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3080 interpreter process. This could cause failures in non-Distutils subprocesses
3081 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003082 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003083 deployment target only in the environment of each build subprocess. It is
3084 still possible to globally override the default by setting
3085 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3086 greater or equal to the default value, the value with which the interpreter
3087 was built.

3116 updating the check interval, so if the user decreases the check interval,
3117 the ticker doesn't have to wind down to zero from the old starting point
3118 before the new interval takes effect. And if the user increases the
3119 interval, it makes sure the new limit takes effect right away rather have an
3120 early task switch before recognizing the new interval.

4118 This prevents user-created self-referencing ordered dictionaries from
4119 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004580- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4581 start byte and the continuation byte(s) are now considered invalid, instead
4582 of the number of bytes specified by the start byte.
4583 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4584 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4585 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4586 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004594- Issue #8748: Fix two issues with comparisons between complex and integer
4595 objects. (1) The comparison could incorrectly return True in some cases
4596 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4597 (2) The comparison raised an OverflowError for large integers, leading
4598 to unpredictable exceptions when combining integers and complex objects
4599 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004601- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004738- Issue #1533: Fix inconsistency in range function argument processing: any
4739 non-float non-integer argument is now converted to an integer (if possible)
4740 using its __int__ method. Previously, only small arguments were treated this
4741 way; larger arguments (those whose __int__ was outside the range of a C long)
4742 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00004750 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00004751 benefit compared to the dynamic memory allocation fallback. Patch by

4777 messages when accessing undefined class attributes because of the cheap
4778 inheritance with the underlying socket object. The cheap inheritance has been
4779 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00004792- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4793 operation raises multiple signals and more than one of those signals is
4794 trapped, the specification determines the order in which the signals should be
4795 handled. In many cases this order wasn't being followed, leading to the wrong
4796 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00004797

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004962
4963Core and Builtins
4964-----------------
4965
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004966- Issue #7301: Add environment variable $PYTHONWARNINGS.
4967
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004968- Issue #8329: Don't return the same lists from select.select when no fds are
4969 changed.
4970
Georg Brandlfee0f442010-05-22 21:26:21 +00004971- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004972 on 64-bit machines. The shift count for either left or right shift is
4973 permitted to be up to sys.maxsize.
4974
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004975- Ensure that tokenization of identifiers is not affected by locale.
4976
Georg Brandlfee0f442010-05-22 21:26:21 +00004977- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004978
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004979- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4980
Georg Brandlfee0f442010-05-22 21:26:21 +00004981- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4982 with a non-empty format string. This is an effort to future-proof user
4983 code. If a derived class does not currently implement __format__ but later
4984 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004985 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004986 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004987
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004988- Issue #8268: Old-style classes (not just instances) now support weak
4989 references.
4990
Georg Brandlfee0f442010-05-22 21:26:21 +00004991- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4992 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004993
Victor Stinnerc7790ed2010-03-22 12:36:28 +00004994- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00004996- Issue #6474: Make error message from passing an inadequate number of keyword
4997 arguments to a function correct.
4998
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004999- Issue #8164: Don't allow lambda functions to have a docstring.
5000
Victor Stinner66644262010-03-10 22:30:19 +00005001- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00005002 (SIGINT). If an error occurs while importing the site module, the error is
5003 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00005004 module.
5005
Collin Winter001a3952010-03-18 21:54:01 +00005006- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00005011- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
5012
Antoine Pitrouf9de5342010-04-05 21:35:07 +00005013- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00005014 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
5015 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00005016
Benjamin Peterson76a23c12010-04-04 23:23:22 +00005017- Issue #8310: Allow dis to examine new style classes.
5018
Georg Brandlfee0f442010-05-22 21:26:21 +00005019- Issue #8257: The Decimal construct now accepts a float instance directly,
5020 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005021
5022 >>> Decimal(1.1)
5023 Decimal('1.100000000000000088817841970012523233890533447265625')
5024
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005025- collections.Counter() now supports a subtract() method.
5026
Georg Brandlfee0f442010-05-22 21:26:21 +00005027- The functools module now has a total_ordering() class decorator to simplify
5028 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00005029
Georg Brandlfee0f442010-05-22 21:26:21 +00005030- The functools module also adds cmp_to_key() as a tool to transition old-style
5031 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00005032
Georg Brandlfee0f442010-05-22 21:26:21 +00005033- Issue #8294: The Fraction constructor now accepts Decimal and float instances
5034 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00005035
Georg Brandlfee0f442010-05-22 21:26:21 +00005036- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5037 InvalidOperation instead of returning False. (Comparisons involving a quiet
5038 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5039 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005040
Georg Brandlfee0f442010-05-22 21:26:21 +00005041- Issue #2531: Comparison operations between floats and Decimal instances now
5042 return a result based on the numeric values of the operands; previously they
5043 returned an arbitrary result based on the relative ordering of id(float) and
5044 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005045
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005046- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005047 argument `-` which tells it to read files to compile from stdin. Each line is
5048 read on demand and the named file is compiled immediately. (Original patch by
5049 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005050
Georg Brandlfee0f442010-05-22 21:26:21 +00005051- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
5052 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00005054- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5055 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005056 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005057
Georg Brandlfee0f442010-05-22 21:26:21 +00005058- Comparisons using one of <, <=, >, >= between a complex instance and a
5059 Fractions instance now raise TypeError instead of returning True/False. This
5060 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5061 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00005062
Michael Foorde6410c52010-03-29 20:04:23 +00005063- Addition of ``WeakSet`` to the ``weakref`` module.

5071
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005072- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00005073 didn't support chflags() (for example ZFS under FreeBSD). The error is now
5074 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005075
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00005076- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
5077 deprecated.
5078
Georg Brandlfee0f442010-05-22 21:26:21 +00005079- Issue #7860: platform.uname now reports the correct 'machine' type when Python
5080 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00005081

5086 existing at the same time, causing a Unicode error when configuration code
5087 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00005088
Georg Brandlfee0f442010-05-22 21:26:21 +00005089- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
5090 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00005091
Antoine Pitroueee91cd2010-03-26 19:27:16 +00005092- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
5093 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
5094 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00005095
Florent Xiclunacf82fa62010-03-21 12:27:20 +00005096- Issue #8179: Fix macpath.realpath() on a non-existing path.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00005116- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00005117 for ``TimedRotatingFileHandler`` by using the modification time of an existing
5118 log file to compute the next rollover time. If the log file does not exist,
5119 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00005120
Georg Brandlba83f822010-03-14 09:50:54 +00005121- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00005129- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
5130 a base64 transfer-encoded payload *after* decoding it; it no longer does.
5131 This is a behavior change, so email's minor version number is now bumped, to
5132 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00005133

Mark Dickinson4846a8e2010-04-03 14:05:10 +00005160- Issue #8300: When passing a non-integer argument to struct.pack with any
5161 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00005165- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
5166 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
5167 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00005168 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5169 inconsistent: __int__ was used for some integer codes but not for others, and
5170 the set of integer codes for which it was used differed between native packing
5171 and standard packing.)

5576-----------------
5577
Georg Brandlba83f822010-03-14 09:50:54 +00005578- The ``__complex__()`` method is now looked up on the class of instances to
5579 make it consistent with other special methods.

5583
Mark Dickinson1b34d252010-01-01 17:27:30 +00005584- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005585 DeprecationWarning when passed a float argument where an integer was expected.
5586 These functions and methods now raise TypeError instead. The majority of the
5587 effects of this change are in the extension modules, but some core functions
5588 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5589 and many unicode/str methods.

5603 of integers: the result of a/b is now correctly rounded for ints a and b (at
5604 least on IEEE 754 platforms), and in particular does not depend on the
5605 internal representation of a long.

5613
Georg Brandlba83f822010-03-14 09:50:54 +00005614 These executables now work properly with the arch(1) command: ``arch -ppc
5615 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00005771- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5772 decimal string that's guaranteed to round back to x under correct rounding
5773 (with round-half-to-even rounding mode). Previously it gave a string based on
5774 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5775 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5776 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005777
Georg Brandlba83f822010-03-14 09:50:54 +00005778- Issue #7117: On almost all platforms: float-to-string and string-to-float
5779 conversions within Python are now correctly rounded. Places these conversions
5780 occur include: str for floats and complex numbers; the float and complex
5781 constructors; old-style and new-style numeric formatting; serialization and
5782 deserialization of floats and complex numbers using marshal, pickle and json;
5783 parsing of float and imaginary literals in Python code; Decimal-to-float
5784 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005785
Georg Brandlba83f822010-03-14 09:50:54 +00005786 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5787 providing correctly-rounded strtod and dtoa C functions. This code is
5788 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5789 the C compiler. There may be a small number of platforms on which correct
5790 operation of this code cannot be guaranteed, so the code is not used: notably,
5791 this applies to platforms where the C double format is not IEEE 754 binary64,
5792 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5793 and Python's configure script is unable to determine how to change the FPU
5794 precision. On these platforms conversions use the platform strtod and dtoa,
5795 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005797- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5798 uses the correctly-rounded string <-> float conversions described above (when
5799 available), and so produces correctly rounded results that will display nicely
5800 under the float repr. There are two related small changes: (1) round now
5801 accepts any class with an ``__index__()`` method for its second argument (but
5802 no longer accepts floats for the second argument), and (2) an excessively
5803 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5804 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005946
Georg Brandlba83f822010-03-14 09:50:54 +00005947 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5948 (2) parsing of strings representing infinities and nans was locale aware; and
5949 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005951- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5952 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5953 but with at least one decimal point and with a default precision
5954 of 12. Previously, the behavior the same but with a default precision of 6.
5955 This more closely matches ``str()``, and reduces surprises when adding
5956 alignment flags to the empty presentation type. This also affects the new
5957 complex.__format__ in the same way.
5958
5959- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5960 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00006155- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on

6157 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00006181- On windows, ``os.chdir()`` given unicode was not working if

6183 this code path is really executed because I cannot move to such directory on
6184 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006186- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6187 element is temporarily replaced with an equivalent frozenset. But the
6188 eventual KeyError would always report the empty ``frozenset()`` as the missing
6189 key. Now it correctly refers to the initial element.

6210 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6211 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6212 of using the replace error handler in PyUnicode_DecodeUTF8().
6213
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006214- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00006217- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

6219 gives improved memory leak detection when running under Valgrind, while taking
6220 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00007494- Issue #5354: New test support function import_fresh_module() makes it easy to
7495 import both normal and optimised versions of modules. test_heapq and
7496 test_warnings have been adjusted to use it, tests for other modules with both
7497 C and Python implementations in the stdlib can be adjusted to use it over
7498 time.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007611- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7612 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7613 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7614 ``printf`` function, whereas PyString_FromFormat has an independent
7615 implementation and uses "%zd" on all platforms for size_t values.
7616 This makes a difference on win64, where ``printf`` needs "%Id" to display
7617 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00007637 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

7640 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7641 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00007788- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7789 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7790 extensions do not automatically benefit from the class attribute
7791 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7792 to their tp_flags field if they care. This is a backwards
7793 compatibility feature; in 3.0, all types will use the cache by
7794 default.
7795
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007796- Keyword arguments can now follow starred arguments. (``f(a, *args,
7797 keyword=23)`` is now valid syntax.)
7798
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007799- ctypes function pointers that are COM methods have a boolean True
7800 value again.
7801
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007802- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7803 by denying s# to parse objects that have a releasebuffer procedure,
7804 and introducing s*.
7805
Georg Brandl1e13ea92008-08-11 09:07:59 +00007806- Issue #3537: Fix an assertion failure when an empty but presized dict
7807 object was stored in the freelist.
7808
Mark Dickinsonb6467572008-08-04 21:30:09 +00007809- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7810 ValueError consistently across platforms.
7811
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007812- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7813 (64bit Unix, for example), unichr() would truncate its argument and return
7814 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7815
Neal Norwitze7d8be82008-07-31 17:17:14 +00007816- Apply security patches from Apple.
7817
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007818- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7819 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7820
Antoine Pitrou92f82162008-07-25 22:22:08 +00007821- Issue #1819: function calls with several named parameters are now on
7822 average 35% faster (as measured by pybench).
7823
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007824- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7825 the python debugger steps into a class statement: the free variables (local
7826 variables defined in an outer scope) would be deleted from the outer scope.
7827
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007828- Issue #2620: Overflow checking when allocating or reallocating memory
7829 was not always being done properly in some python types and extension
7830 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7831 all been updated to perform better checks and places in the code that
7832 would previously leak memory on the error path when such an allocation
7833 failed have been fixed.

7837
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007838- Issue #3612: Added some missing basic types in ctypes.wintypes.
7839
Benjamin Petersone977ad42008-08-20 01:42:01 +00007840- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7841 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7842
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007843- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7844 version reported by these tools does not necessarily follow the python
7845 version numbering scheme, so the module is less strict when parsing it.
7846
Nick Coghlanf70385a2008-08-18 12:42:46 +00007847- Issue #2235: Added Py3k warnings for types which will become unhashable
7848 under the stricter __hash__ inheritance rules in 3.0. Several types
7849 which did not meet the rules for hash invariants and were already
7850 unhashable in 3.0 have now been explicitly flagged as unhashable in
7851 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7852 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7853
Brett Cannon88f801d2008-08-18 00:46:22 +00007854- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7855 imported into the module but exposed as part of the module's API.
7856
Brett Cannon7b96f072008-08-18 00:41:11 +00007857- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7858
Brett Cannon46225e72008-08-18 00:36:52 +00007859- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7860
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007861- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7862
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007863- Issue #3575: Incremental decoder's decode function now takes bytearray
7864 by using 's*' instead of 't#'.
7865
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007866- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007867 fails unicode conversion on 2nd parameter. (windows only)
7868
Georg Brandl222e2082010-08-01 22:27:39 +00007869- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007870 in a redirect.
7871
Brett Cannonabe423e2008-08-16 21:47:07 +00007872- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007873 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007874
Facundo Batistaeb90b782008-08-16 14:44:07 +00007875- Issue #2776: fixed small issue when handling an URL with double slash
7876 after a 302 response in the case of not going through a proxy.
7877
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007878- Issue #2676: in the email package, content-type parsing was hanging on
7879 pathological input because of quadratic or exponential behaviour of a
7880 regular expression.
7881
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007882- Issue #3476: binary buffered reading through the new "io" library is now
7883 thread-safe.
7884
Brett Cannonbf3157b2008-08-14 05:00:03 +00007885- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7886 since mimetools itself is deprecated. Because modules are cached, all
7887 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7888
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007889- Issue #3134: shutil referenced undefined WindowsError symbol.
7890
Robert Schuppenies14646332008-08-10 11:01:53 +00007891- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7892 menu entries were not deleted.
7893
Brett Cannon83e81842008-08-09 23:30:55 +00007894- Copied the implementation of reduce() to _functools.reduce() to have a
7895 version that did not raise a DeprecationWarning under -3.
7896
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007897- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7898 a MemoryError rather than silently stop the iteration.
7899
Guido van Rossum59ce9012008-08-09 14:55:34 +00007900- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7901 to _sre.compile() will now be rejected. This should not affect anybody
7902 since the re.compile() function never generates invalid re-bytecode.
7903
Skip Montanaroa032bf42008-08-08 22:52:51 +00007904- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7905 upon first access it can be automatically initialized from the csv file if
7906 it wasn't initialized during instantiation.
7907
Brett Cannon3aa2a492008-08-06 22:28:09 +00007908- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7909 the reload() built-in has been removed.
7910
Brett Cannon7e30b672008-08-04 21:52:25 +00007911- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007912 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7920 raised an AttributeError.
7921
Benjamin Peterson01a24322008-07-28 23:35:27 +00007922- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007923 asking for a specific length. This problem only affected files opened
7924 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007925
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007926- Issue #3449: Update decimal module to use most recent specification
7927 (v. 1.68) and tests (v. 2.58) from IBM.
7928
Georg Brandl222e2082010-08-01 22:27:39 +00007929- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007930

7944- Issue #3389: Allow resolving dotted names for handlers in logging
7945 configuration files.
7946
7947- Deprecate the sunaudio module for removal in Python 3.0.
7948
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007949- Issue #3394: zipfile.writestr sets external attributes when passed a
7950 file name rather than a ZipInfo instance, so files are extracted with
7951 mode 0600 rather than 000 under Unix.
7952
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007953- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7954 argument in python 2.5, this broke code that subclassed Popen to include its
7955 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007965- Issue #2235: the C API function PyObject_HashNotImplemented and its
7966 interaction with the tp_hash slot (added in 2.6b2) are now documented
7967
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007968- Issue #643841: The language reference now provides more detailed
7969 coverage of the lookup process for special methods. The disclaimers
7970 regarding lack of coverage of new-style classes have also been
7971 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007979Core and Builtins
7980-----------------
7981
Georg Brandl3e483f62008-07-16 22:57:41 +00007982- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7983 its methods now allow for items objects that can be converted to
7984 an integer using operator.index().
7985
Mark Dickinson64b7e502008-07-16 09:40:03 +00007986- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7987 produced a ValueError instead of giving the correct float.
7988
Eric Smitha5fa5a22008-07-16 00:11:49 +00007989- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7990 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7991
Mark Dickinson7103aa42008-07-15 19:08:33 +00007992- Issue #3008: the float type has a new instance method 'float.hex'
7993 and a new class method 'float.fromhex' to convert floating-point
7994 numbers to and from hexadecimal strings, respectively.
7995
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007996- Issue #2235: __hash__ is once again inherited by default. To allow
7997 collections.Hashable to remain meaningful in the presence of the
7998 default hash implementation (object.__hash__), it is now possible
7999 to explicit block inheritance of hash by setting __hash__=None at
8000 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8001 level.
8002
Nick Coghlanb028f502008-07-13 14:52:36 +00008003- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8004 the parent module cannot be found while performing an absolute import.
8005 This means that an incorrectly defined __package__ attribute will
8006 now only prevent relative imports in that module rather than causing
8007 all imports from that module to fail.
8008
Nick Coghlan14ff9942008-07-08 14:21:42 +00008009- Issue #2517: Allow unicode messages in Exceptions again by correctly
8010 bypassing the instance dictionary when looking up __unicode__ on
8011 new-style classes.
8012
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008013- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8014 set to a custom object whose write() method happens to install
8015 another file in sys.stdout.
8016
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008017- Issue #3088: Corrected a race condition in classes derived from
8018 threading.local: the first member set by a thread could be saved in
8019 another thread's dictionary.
8020
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008021- Issue #3004: Minor change to slice.indices(): the start and stop
8022 arguments are now treated identically, making the behaviour easier
8023 to describe and understand. For example, slice(None, -10,
8024 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8025 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8026 10, -1).
8027
Georg Brandl278fc502008-07-19 12:46:12 +00008028- Issue #3219: Calling a function with repeated keyword arguments,
8029 f(a=2, a=23), would not cause a syntax error. This was a regression
8030 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008031
Georg Brandl278fc502008-07-19 12:46:12 +00008032- Issue #2862: Make int and float freelist management consistent with
8033 other freelists. Changes their CompactFreeList apis into
8034 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00008035

8037-------
8038
Thomas Heller57adf222008-08-14 19:10:48 +00008039- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
8040 api functions without holding the GIL, which could lead to a fatal
8041 error when they failed.
8042
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008043- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
8044
Jesse Noller7fb96402008-07-17 21:01:05 +00008045- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

Jesse Noller13e9d582008-07-16 14:32:36 +00008051- Issue #3125: Remove copy_reg in multiprocessing and replace it with
8052 ForkingPickler.register() to resolve conflict with ctypes.
8053
Vinay Sajip51e65192008-07-18 09:01:10 +00008054- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00008055
Thomas Heller880f5292008-07-15 19:39:38 +00008056- Issue #3313: Fixed a crash when a failed dlopen() call does not set
8057 a valid dlerror() message.
8058
Thomas Heller2bad6572008-07-15 17:19:50 +00008059- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8060 incomplete structure was created.
8061
Brett Cannon3d0b9f02008-07-13 01:15:07 +00008062- Issue #3339: dummy_thread.acquire() should not return None.
8063
Raymond Hettingerb01713e2008-07-10 14:34:57 +00008064- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
8065
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008066- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008067
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008068- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8069 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008070 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008071 content-length. The problem had been corrected in the 2.4 branch, but never
8072 merged into trunk.

8477 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008478 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008479
8480 This is controlled by the configure argument ``--with-universal-archs``:
8481
8482 - ``--with-universal-archs=all``: install 4-way universal
8483
8484 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8485
8486 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8487
8488 This option should be used in combination with ``--enable-universalsdk=``.
8489
8490 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 +00008539- Issue #1631171: Re-implement the 'warnings' module in C (the
8540 original Python code has been kept as backup). This will allow for
8541 using the 'warning's machinery in such places as the parser where
8542 use of pure Python code is not possible. Both the ``showarning()``
8543 and ``formatwarning()`` gain an optional 'line' argument which is
8544 not called by default for backwards-compatibility reasons. Setting
8545 ``warnings.showwarning()`` to an implementation that lacks support
8546 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008609- Issue #2550: The approach used by client/server code for obtaining
8610 ports to listen on in network-oriented tests has been refined in an
8611 effort to facilitate running multiple instances of the entire
8612 regression test suite in parallel without issue.
8613 test_support.bind_port() has been fixed such that it will always
8614 return a unique port -- which wasn't always the case with the
8615 previous implementation, especially if socket options had been set
8616 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8617 new implementation of bind_port() will actually raise an exception
8618 if it is passed an AF_INET/SOCK_STREAM socket with either the
8619 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8620 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8621 the socket it's been passed. This currently only applies to
8622 Windows. This option prevents any other sockets from binding to the
8623 host/port we've bound to, thus removing the possibility of the
8624 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8625 when a second SOCK_STREAM socket binds and accepts to a host/port
8626 that's already been bound by another socket. The optional preferred
8627 port parameter to bind_port() has been removed. Under no
8628 circumstances should tests be hard coding ports!
8629
8630 test_support.find_unused_port() has also been introduced, which will
8631 pass a temporary socket object to bind_port() in order to obtain an
8632 unused port. The temporary socket object is then closed and
8633 deleted, and the port is returned. This method should only be used
8634 for obtaining an unused port in order to pass to an external program
8635 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8636 a parameter to a server-oriented class that doesn't give you direct
8637 access to the underlying socket used.
8638
8639 Finally, test_support.HOST has been introduced, which should be used
8640 for the host argument of any relevant socket calls (i.e. bind and
8641 connect).

8646 test_asynchat and test_socket_ssl.
8647
Georg Brandl3ee81df2008-05-17 18:14:43 +00008648 It is now possible for multiple instances of the regression test
8649 suite to run in parallel without issue.

8916-----------------
8917
Fred Drakea8ee94b2008-03-01 02:45:07 +00008918- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008919 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008920
Georg Brandlad61bc82008-02-23 15:11:18 +00008921- Issue #2067: file.__exit__() now calls subclasses' close() method.
8922
8923- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008924
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008925- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008926 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008927
Eric Smitha73fbe72008-02-23 03:09:44 +00008928- Added the future_builtins module, which contains hex() and oct().
8929 These are the PEP 3127 version of these functions, designed to be
8930 compatible with the hex() and oct() builtins from Python 3.0. They
8931 differ slightly in their output formats from the existing, unchanged
8932 Python 2.6 builtins. The expected usage of the future_builtins
8933 module is:
8934 from future_builtins import hex, oct
8935
Eric Smith7ef40bf2008-02-20 23:34:22 +00008936- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8937 exponents for exponents with absolute value < 100. Follows C99
8938 standard. This is a change on Windows, which would use 3 digits.
8939 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8940 so that any alterations it does to the resulting string will be
8941 available in stringlib/formatter.h (for float.__format__).
8942
Eric Smith5a3c1352008-02-19 13:21:56 +00008943- Implemented PEP 3101, Advanced String Formatting. This adds a new
8944 builtin format(); a format() method for str and unicode; a
8945 __format__() method to object, str, unicode, int, long, float, and
8946 datetime; the class string.Formatter; and the C API
8947 PyObject_Format().
8948
Georg Brandl3ee81df2008-05-17 18:14:43 +00008949- Fixed several potential crashes, all caused by specially crafted
8950 __del__ methods exploiting objects in temporarily inconsistent
8951 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008952
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008953- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008954 prevent a possible crash: an Abstract Base Class would try to access
8955 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008956
Georg Brandl3ee81df2008-05-17 18:14:43 +00008957- Fixed repr() and str() of complex numbers with infinity or nan as
8958 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008959
Georg Brandl3ee81df2008-05-17 18:14:43 +00008960- Clear all free lists during a gc.collect() of the highest generation
8961 in order to allow pymalloc to free more arenas. Python may give back
8962 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008963
Georg Brandl3ee81df2008-05-17 18:14:43 +00008964- Issue #2045: Fix an infinite recursion triggered when printing a
8965 subclass of collections.defaultdict, if its default_factory is set
8966 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008967
Christian Heimesf75dbef2008-02-08 00:11:31 +00008968- Fixed a minor memory leak in dictobject.c. The content of the free
8969 list was not freed on interpreter shutdown.
8970
Georg Brandl21e99f42010-03-07 15:23:59 +00008971- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008972 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008973
Georg Brandl3ee81df2008-05-17 18:14:43 +00008974- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8975 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008976 to compact the internal free lists of pre-allocted ints and floats.
8977
Georg Brandl3ee81df2008-05-17 18:14:43 +00008978- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8979 calls. Python expected the return type int but the fork familie
8980 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008981
Georg Brandl3ee81df2008-05-17 18:14:43 +00008982- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8983 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008984
Georg Brandl3ee81df2008-05-17 18:14:43 +00008985- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8986 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008987
Georg Brandl3ee81df2008-05-17 18:14:43 +00008988- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8989 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008990
Georg Brandl3ee81df2008-05-17 18:14:43 +00008991- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8992 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008993
Georg Brandl3ee81df2008-05-17 18:14:43 +00008994- Patch #1473257: generator objects gain a gi_code attribute. This is
8995 the same object as the func_code attribute of the function that
8996 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008997
Georg Brandl3ee81df2008-05-17 18:14:43 +00008998- Issue #1920: "while 0" statements were completely removed by the
8999 compiler, even in the presence of an "else" clause, which is
9000 supposed to be run when the condition is false. Now the compiler
9001 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009002
Guido van Rossumeead05f2008-01-24 18:21:02 +00009003- A few crashers fixed: weakref_in_del.py (issue #1377858);
9004 loosing_dict_ref.py (issue #1303614, test67.py);
9005 borrowed_ref_[34].py (not in tracker).
9006
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009007- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009008 suppressed while an extension is loaded by calling SetErrorMode in
9009 dynload_win.c. The error is still reported properly.
9010
Georg Brandl3ee81df2008-05-17 18:14:43 +00009011- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009012 several extension methods and modules do not work without unicode
9013 support.
9014
Georg Brandl26543b12008-01-21 18:36:51 +00009015- Issue #1882: when compiling code from a string, encoding cookies in the
9016 second line of code were not always recognized correctly.
9017
Georg Brandl14404b62008-01-19 19:27:05 +00009018- Issue #1679: "0x" was taken as a valid integer literal.
9019
Georg Brandl6caad7d2008-01-26 14:19:22 +00009020- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009021 added.
9022
Christian Heimesc94e2b52008-01-14 04:13:37 +00009023- sys.float_info / PyFloat_GetInfo: The floating point information
9024 object was converted from a dict to a specialized structseq object.
9025
Georg Brandl3ee81df2008-05-17 18:14:43 +00009026- Patch #1816: Added sys.flags structseq. It exposes the status of
9027 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009028
Georg Brandl3ee81df2008-05-17 18:14:43 +00009029- Objects/structseq.c: Implemented new structseq representation. The
9030 patch makes structseqs (e.g. the return value of os.stat) more
9031 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009032
Georg Brandl3ee81df2008-05-17 18:14:43 +00009033- Patch #1700288: added a type attribute cache that caches method
9034 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009035
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009036- Bug #1776: __import__() no longer accepts filenames on any platform.
9037 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009038
Georg Brandlaed6c662008-01-07 17:25:53 +00009039- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9040
Georg Brandl3ee81df2008-05-17 18:14:43 +00009041- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9042 envvar and sys.dont_write_bytecode attribute. All these can be set
9043 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009044
Georg Brandl3ee81df2008-05-17 18:14:43 +00009045- Improve some exception messages when Windows fails to load an
9046 extension module. Now we get for example '%1 is not a valid Win32
9047 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009048
Georg Brandl3ee81df2008-05-17 18:14:43 +00009049- Bug #1481296: Fixed long(float('nan')) != 0L.

9052 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009053
Christian Heimes0a8143f2007-12-18 23:22:54 +00009054- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009055 and INF. float("nan"), float("inf") and float("-inf") now work on
9056 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009057
Georg Brandl3ee81df2008-05-17 18:14:43 +00009058- Compiler now generates simpler and faster code for dictionary
9059 literals. The oparg for BUILD_MAP now indicates an estimated
9060 dictionary size. There is a new opcode, STORE_MAP, for adding
9061 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009062
Georg Brandl3ee81df2008-05-17 18:14:43 +00009063- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009095- Issue #1265: Fix a problem with sys.settrace, if the tracing
9096 function uses a generator expression when at the same time the
9097 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009098
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009099- sets and frozensets now have an isdisjoint() method.
9100
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009101- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00009103- Fix warnings found by the new version of the Coverity checker.
9104
Georg Brandl21e99f42010-03-07 15:23:59 +00009105- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009106 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9107 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009108
Georg Brandl3ee81df2008-05-17 18:14:43 +00009109- Issue #1686386: Tuple's tp_repr did not take into account the
9110 possibility of having a self-referential tuple, which is possible
9111 from C code. Nor did object's tp_str consider that a type's tp_str
9112 could do something that could lead to an inifinite recursion.
9113 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9114 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009115
Georg Brandl3ee81df2008-05-17 18:14:43 +00009116- Issue #1164: It was possible to trigger deadlock when using the
9117 'print' statement to write to a file since the GIL was not released
9118 as needed. Now PyObject_Print() does the right thing along with
9119 various tp_print implementations of the built-in types and those in
9120 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009121
Georg Brandl3ee81df2008-05-17 18:14:43 +00009122- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00009129- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009130 PyObject_Call() never calling back out to Python code to trigger
9131 recursion depth updates/checks. Required the creation of a static
9132 RuntimeError instance in case normalizing an exception put the
9133 recursion check value past its limit. Fixes crashers
9134 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00009149- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009150 __*__ attributes. (Some already existed, e.g., __doc__ and
9151 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009152

9158
Collin Winter62903052007-05-18 23:11:24 +00009159- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009160 "except E as target:". This is to provide forwards compatibility
9161 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009169 setting a plain string, ie don't expand to single letter identifiers.
9170
Raymond Hettinger13936692007-04-11 18:40:58 +00009171- Request #1191699: Slices can now be pickled.

9181
Guido van Rossum143b5642007-03-23 04:58:42 +00009182- Bug #1683368: The object.__init__() and object.__new__() methods are
9183 now stricter in rejecting excess arguments. The only time when
9184 either allows excess arguments is when it is not overridden and the
9185 other one is. For backwards compatibility, when both are
9186 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009187 warning later). Also, type.__init__() insists on the same signature
9188 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009190- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9191 object to complex using its __complex__() method before falling back
9192 to the __float__() method. Therefore, the functions in the cmath
9193 module now can operate on objects that define a __complex__()
9194 method.

9211
Georg Brandl7b9c5552007-03-12 14:30:05 +00009212- Bug #1678647: write a newline after printing an exception in any
9213 case, even when converting the value to a string failed.
9214
Georg Brandl871f1bc2007-03-12 13:17:36 +00009215- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009216 its argument, if it exists. If not, it will work like before. This
9217 allows customizing the output of dir() in the presence of a
9218 __getattr__().

9228 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009229
Georg Brandlaa2321b2007-03-07 00:40:28 +00009230- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009231 makes the filenames the warning module prints much more sensible
9232 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009233

Georg Brandl0fca97a2007-03-05 22:28:08 +00009245- Patch #1674228: when assigning a slice (old-style), check for the
9246 sq_ass_slice instead of the sq_slice slot.
9247
Georg Brandl3ee81df2008-05-17 18:14:43 +00009248- When printing an unraisable error, don't print exceptions. before

9858 Python would crash instead of raising an error.
9859

9872
Georg Brandl3ee81df2008-05-17 18:14:43 +00009873- unittest now verifies more of its assumptions. In particular,
9874 TestCase and TestSuite subclasses (not instances) are no longer
9875 accepted in TestSuite.addTest(). This should cause no
9876 incompatibility since it never made sense with ordinary subclasses
9877 -- the failure just occurred later, with a more cumbersome
9878 exception.

10147 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010148
Georg Brandl3ee81df2008-05-17 18:14:43 +000010149- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010158- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010159 that the SMTP.starttls() caller no longer needs to call ehlo()
10160 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010161 does not claim to support starttls. Adds the
10162 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010205- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010206 works as expected. ``mmap.find`` also takes an optional ``end``

10243 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Georg Brandl3ee81df2008-05-17 18:14:43 +000010261 time so that opening a database previously created with the DB_DUP
10262 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10263 opens. Specifically: dictionary assignment to a DB object will
10264 replace all values for a given key when the database allows
10265 duplicate values. DB users should use DB.put(k, v) when they want
10266 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010267

10273 characters with ASCII value less than 32. Also, it correctly quotes
10274 dots only if they occur on a single line, as opposed to the previous
10275 behavior of quoting dots if they are the second character of any
10276 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010277

10604-----
10605
Georg Brandl3ee81df2008-05-17 18:14:43 +000010606- Unified naming convention for free lists and their limits. All free
10607 lists in Object/ are named ``free_list``, the counter ``numfree``
10608 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10609 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010610
Georg Brandl3ee81df2008-05-17 18:14:43 +000010611- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10612 to ``PyTuple_SetItem``, it can be used to populate a brand new
10613 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010614
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010615- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

10618 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10619 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010620
10621- Patch #1720595: add T_BOOL to the range of structmember types.
10622
10623- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10624 ``PyFloat_GetInfo()`` to the float API.
10625
Georg Brandl3ee81df2008-05-17 18:14:43 +000010626- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10627 of w# format code incorrectly truncated the length to an int, even
10628 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10629 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010630
Georg Brandl3ee81df2008-05-17 18:14:43 +000010631- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10632 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010634- PEP 3123: Provide forward compatibility with Python 3.0, while
10635 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10636 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010637
Georg Brandl3ee81df2008-05-17 18:14:43 +000010638- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10639 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010640
10641- Patch #1733960: Allow T_LONGLONG to accept ints.

10648
10649- Fix some leftovers from the conversion from int to Py_ssize_t
10650 (relevant to strings and sequences of more than 2**31 items).
10651
10652- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10653 outside of pystate.c and should not be necessary.
10654
Georg Brandl3ee81df2008-05-17 18:14:43 +000010655- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10656 absolute imports. In earlier versions they might have used relative
10657 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010658
Georg Brandl3ee81df2008-05-17 18:14:43 +000010659- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10660 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010661
Georg Brandl3ee81df2008-05-17 18:14:43 +000010662- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010668- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10669 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10670 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10671 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010672
Georg Brandl3ee81df2008-05-17 18:14:43 +000010673- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +000010685- Removed the macfs module. It had been deprecated since Python 2.5.
10686 This lead to the deprecation of macostools.touched() as it relied
10687 solely on macfs and was a no-op under OS X.
