1444 32-bit-only installer Pythons on systems with Xcode 4 (currently
1445 OS X 10.8, 10.7, and optionally 10.6).
1446 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1447 * Since Xcode 4 removes ppc support, extension module builds now
1448 check for ppc compiler support and by default remove ppc and
1449 ppc64 archs when they are not available.
1450 * Extension module builds now revert to using system installed
1451 headers and libs (/usr and /System/Library) if the SDK used
1452 to build the interpreter is not installed or has moved.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001806- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1807 int.__pow__. These overflow checks were causing int.__pow__ to produce
1808 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001809 compiler optimizing the check away. Also fix similar overflow checks
1810 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1811 bugs caused test failures with recent versions of Clang.

1824 and its type get caught in a reference cycle, and the instance's

Florent Xiclunac2279652012-02-12 14:49:03 +01001879- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001880 has left two versions of customize_compiler, the original in
1881 distutils.sysconfig and another copy in distutils.ccompiler, with some

1884 is the case in 3.x.
1885
Ned Deily0d0ea482012-02-10 12:59:06 +01001886- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1887 Distutils-based packages with C extension modules may fail because
1888 Apple has removed gcc-4.2, the version used to build python.org
1889 64-bit/32-bit Pythons. If the user does not explicitly override
1890 the default C compiler by setting the CC environment variable,
1891 Distutils will now attempt to compile extension modules with clang
1892 if gcc-4.2 is required but not found. Also as a convenience, if
1893 the user does explicitly set CC, substitute its value as the default
1894 compiler in the Distutils LDSHARED configuration variable for OS X.
1895 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1896 SDK, neither of which are available in Xcode 4. This change does not
1897 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002147- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2148 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2149 interpreter process. This could cause failures in non-Distutils subprocesses
2150 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002151 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002152 deployment target only in the environment of each build subprocess. It is
2153 still possible to globally override the default by setting
2154 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2155 greater or equal to the default value, the value with which the interpreter
2156 was built.

2168 connection if its getresponse() method fails with a socket error. Patch
2169 written by Ezio Melotti.
2170

2183
Barry Warsawc5643282011-07-19 17:06:30 -04002184- sys.setcheckinterval() now updates the current ticker count as well as
2185 updating the check interval, so if the user decreases the check interval,
2186 the ticker doesn't have to wind down to zero from the old starting point
2187 before the new interval takes effect. And if the user increases the
2188 interval, it makes sure the new limit takes effect right away rather have an
2189 early task switch before recognizing the new interval.

3170 This prevents user-created self-referencing ordered dictionaries from
3171 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003632- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3633 start byte and the continuation byte(s) are now considered invalid, instead
3634 of the number of bytes specified by the start byte.
3635 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3636 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3637 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3638 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003646- Issue #8748: Fix two issues with comparisons between complex and integer
3647 objects. (1) The comparison could incorrectly return True in some cases
3648 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3649 (2) The comparison raised an OverflowError for large integers, leading
3650 to unpredictable exceptions when combining integers and complex objects
3651 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003653- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00003790- Issue #1533: Fix inconsistency in range function argument processing: any
3791 non-float non-integer argument is now converted to an integer (if possible)
3792 using its __int__ method. Previously, only small arguments were treated this
3793 way; larger arguments (those whose __int__ was outside the range of a C long)
3794 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00003802 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00003803 benefit compared to the dynamic memory allocation fallback. Patch by
3804 Charles-François Natali.

3829 messages when accessing undefined class attributes because of the cheap
3830 inheritance with the underlying socket object. The cheap inheritance has been
3831 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00003832

Georg Brandlfee0f442010-05-22 21:26:21 +00003844- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3845 operation raises multiple signals and more than one of those signals is
3846 trapped, the specification determines the order in which the signals should be
3847 handled. In many cases this order wasn't being followed, leading to the wrong
3848 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00003849

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004014
4015Core and Builtins
4016-----------------
4017
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004018- Issue #7301: Add environment variable $PYTHONWARNINGS.
4019
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004020- Issue #8329: Don't return the same lists from select.select when no fds are
4021 changed.
4022
Georg Brandlfee0f442010-05-22 21:26:21 +00004023- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004024 on 64-bit machines. The shift count for either left or right shift is
4025 permitted to be up to sys.maxsize.
4026
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004027- Ensure that tokenization of identifiers is not affected by locale.
4028
Georg Brandlfee0f442010-05-22 21:26:21 +00004029- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004030
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004031- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4032
Georg Brandlfee0f442010-05-22 21:26:21 +00004033- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4034 with a non-empty format string. This is an effort to future-proof user
4035 code. If a derived class does not currently implement __format__ but later
4036 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004037 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004038 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004039
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004040- Issue #8268: Old-style classes (not just instances) now support weak
4041 references.
4042
Georg Brandlfee0f442010-05-22 21:26:21 +00004043- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4044 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004045
Victor Stinnerc7790ed2010-03-22 12:36:28 +00004046- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00004047
Benjamin Peterson96545892010-03-21 20:21:00 +00004048- Issue #6474: Make error message from passing an inadequate number of keyword
4049 arguments to a function correct.
4050
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004051- Issue #8164: Don't allow lambda functions to have a docstring.
4052
Victor Stinner66644262010-03-10 22:30:19 +00004053- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004054 (SIGINT). If an error occurs while importing the site module, the error is
4055 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004056 module.
4057
Collin Winter001a3952010-03-18 21:54:01 +00004058- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00004063- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
4064
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004065- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00004066 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4067 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004068
Benjamin Peterson76a23c12010-04-04 23:23:22 +00004069- Issue #8310: Allow dis to examine new style classes.
4070
Georg Brandlfee0f442010-05-22 21:26:21 +00004071- Issue #8257: The Decimal construct now accepts a float instance directly,
4072 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004073
4074 >>> Decimal(1.1)
4075 Decimal('1.100000000000000088817841970012523233890533447265625')
4076
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004077- collections.Counter() now supports a subtract() method.
4078
Georg Brandlfee0f442010-05-22 21:26:21 +00004079- The functools module now has a total_ordering() class decorator to simplify
4080 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004081
Georg Brandlfee0f442010-05-22 21:26:21 +00004082- The functools module also adds cmp_to_key() as a tool to transition old-style
4083 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004084
Georg Brandlfee0f442010-05-22 21:26:21 +00004085- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4086 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004087
Georg Brandlfee0f442010-05-22 21:26:21 +00004088- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4089 InvalidOperation instead of returning False. (Comparisons involving a quiet
4090 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4091 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004092
Georg Brandlfee0f442010-05-22 21:26:21 +00004093- Issue #2531: Comparison operations between floats and Decimal instances now
4094 return a result based on the numeric values of the operands; previously they
4095 returned an arbitrary result based on the relative ordering of id(float) and
4096 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004097
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004098- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004099 argument `-` which tells it to read files to compile from stdin. Each line is
4100 read on demand and the named file is compiled immediately. (Original patch by
4101 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004102
Georg Brandlfee0f442010-05-22 21:26:21 +00004103- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4104 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00004106- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4107 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004108 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004109
Georg Brandlfee0f442010-05-22 21:26:21 +00004110- Comparisons using one of <, <=, >, >= between a complex instance and a
4111 Fractions instance now raise TypeError instead of returning True/False. This
4112 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4113 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004114
Michael Foorde6410c52010-03-29 20:04:23 +00004115- Addition of ``WeakSet`` to the ``weakref`` module.

4123
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004124- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004125 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4126 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004127
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004128- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4129 deprecated.
4130
Georg Brandlfee0f442010-05-22 21:26:21 +00004131- Issue #7860: platform.uname now reports the correct 'machine' type when Python
4132 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00004133

4138 existing at the same time, causing a Unicode error when configuration code
4139 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00004140
Georg Brandlfee0f442010-05-22 21:26:21 +00004141- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
4142 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00004143
Antoine Pitroueee91cd2010-03-26 19:27:16 +00004144- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
4145 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4146 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00004147
Florent Xiclunacf82fa62010-03-21 12:27:20 +00004148- Issue #8179: Fix macpath.realpath() on a non-existing path.

4162 locale.
Matthias Klose358e7ff2010-03-15 13:42:23 +00004163
Georg Brandlfee0f442010-05-22 21:26:21 +00004164- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set

Vinay Sajipecfa08f2010-03-12 09:16:10 +00004168- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00004169 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4170 log file to compute the next rollover time. If the log file does not exist,
4171 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004172
Georg Brandlba83f822010-03-14 09:50:54 +00004173- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

4180
Georg Brandlba83f822010-03-14 09:50:54 +00004181- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4182 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4183 This is a behavior change, so email's minor version number is now bumped, to
4184 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004212- Issue #8300: When passing a non-integer argument to struct.pack with any
4213 integer format code, struct.pack first attempts to convert the non-integer
4214 using its __index__ method. If that method is non-existent or raises
4215 TypeError it goes on to try the __int__ method, as described below.
4216
Georg Brandlba83f822010-03-14 09:50:54 +00004217- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4218 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4219 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004220 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4221 inconsistent: __int__ was used for some integer codes but not for others, and
4222 the set of integer codes for which it was used differed between native packing
4223 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004475- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4476 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4477 returning NULL. The macro now returns a statically allocated empty string

4628-----------------
4629
Georg Brandlba83f822010-03-14 09:50:54 +00004630- The ``__complex__()`` method is now looked up on the class of instances to
4631 make it consistent with other special methods.

4635
Mark Dickinson1b34d252010-01-01 17:27:30 +00004636- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004637 DeprecationWarning when passed a float argument where an integer was expected.
4638 These functions and methods now raise TypeError instead. The majority of the
4639 effects of this change are in the extension modules, but some core functions
4640 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4641 and many unicode/str methods.

4653
Georg Brandlba83f822010-03-14 09:50:54 +00004654- Issue #1811: Improve accuracy and cross-platform consistency for true division
4655 of integers: the result of a/b is now correctly rounded for ints a and b (at
4656 least on IEEE 754 platforms), and in particular does not depend on the
4657 internal representation of a long.

4665
Georg Brandlba83f822010-03-14 09:50:54 +00004666 These executables now work properly with the arch(1) command: ``arch -ppc
4667 python`` will start a universal binary version of python in PPC mode (unlike

4807 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004808

4810 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00004823- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4824 decimal string that's guaranteed to round back to x under correct rounding
4825 (with round-half-to-even rounding mode). Previously it gave a string based on
4826 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4827 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4828 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004829
Georg Brandlba83f822010-03-14 09:50:54 +00004830- Issue #7117: On almost all platforms: float-to-string and string-to-float
4831 conversions within Python are now correctly rounded. Places these conversions
4832 occur include: str for floats and complex numbers; the float and complex
4833 constructors; old-style and new-style numeric formatting; serialization and
4834 deserialization of floats and complex numbers using marshal, pickle and json;
4835 parsing of float and imaginary literals in Python code; Decimal-to-float
4836 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004837
Georg Brandlba83f822010-03-14 09:50:54 +00004838 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4839 providing correctly-rounded strtod and dtoa C functions. This code is
4840 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4841 the C compiler. There may be a small number of platforms on which correct
4842 operation of this code cannot be guaranteed, so the code is not used: notably,
4843 this applies to platforms where the C double format is not IEEE 754 binary64,
4844 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4845 and Python's configure script is unable to determine how to change the FPU
4846 precision. On these platforms conversions use the platform strtod and dtoa,
4847 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004848
Georg Brandlba83f822010-03-14 09:50:54 +00004849- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4850 uses the correctly-rounded string <-> float conversions described above (when
4851 available), and so produces correctly rounded results that will display nicely
4852 under the float repr. There are two related small changes: (1) round now
4853 accepts any class with an ``__index__()`` method for its second argument (but
4854 no longer accepts floats for the second argument), and (2) an excessively
4855 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4856 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004999 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5000 (2) parsing of strings representing infinities and nans was locale aware; and
5001 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005003- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5004 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5005 but with at least one decimal point and with a default precision
5006 of 12. Previously, the behavior the same but with a default precision of 6.
5007 This more closely matches ``str()``, and reduces surprises when adding
5008 alignment flags to the empty presentation type. This also affects the new
5009 complex.__format__ in the same way.
5010
5011- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00005074 untrackable objects are not tracked by the garbage collector. This can reduce

5083 internal representation of integers, for performance reasons. Base 2**30 is
5084 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00005187- Issue #4597: Fixed exception handling when the __exit__ function of a context
5188 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00005189

Georg Brandlba83f822010-03-14 09:50:54 +00005192- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5193 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5194 instances. On a typical machine this saves 3 bytes of memory (on average) per
5195 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005197- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
5198 interpreter to abort ("Fatal Python error: Could not reset the stack!")
5199 instead of throwing a MemoryError.
5200
Georg Brandlba83f822010-03-14 09:50:54 +00005201- Issue #3689: The list reversed iterator now supports __length_hint__ instead
5202 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00005203
Benjamin Petersonc078f922008-11-21 22:27:24 +00005204- Issue #4367: Python would segfault during compiling when the unicodedata
5205 module couldn't be imported and \N escapes were present.
5206
Georg Brandlba83f822010-03-14 09:50:54 +00005207- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5208 file objects with closefd=False. The file descriptor is still kept open but
5209 the file object behaves like a closed file. The ``FileIO`` object also got a
5210 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00005211
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005212- Issue #4348: Some bytearray methods returned that didn't cause any change to
5213 the bytearray, returned the same bytearray instead of a copy.
5214
Georg Brandlba83f822010-03-14 09:50:54 +00005215- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

5218
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00005219- Issue #4048: The parser module now correctly validates relative imports.
5220
Benjamin Petersondcee09d2008-10-31 02:16:05 +00005221- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
5222 exec statement.
5223
Georg Brandlba83f822010-03-14 09:50:54 +00005224- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
5225 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00005226
Benjamin Petersonbdca9422008-10-26 20:21:13 +00005227- Issue #4209: Enabling unicode_literals and the print_function in the same
5228 __future__ import didn't work.
5229
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005230- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005231 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005232
Georg Brandlba83f822010-03-14 09:50:54 +00005233- On windows, ``os.chdir()`` given unicode was not working if
5234 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5235 this code path is really executed because I cannot move to such directory on
5236 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005237
Georg Brandlba83f822010-03-14 09:50:54 +00005238- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5239 element is temporarily replaced with an equivalent frozenset. But the
5240 eventual KeyError would always report the empty ``frozenset()`` as the missing
5241 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00005242
Georg Brandlba83f822010-03-14 09:50:54 +00005243- Issue #4509: Various issues surrounding resize of bytearray objects to which
5244 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00005245
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00005246- Issue #4748: Lambda generators no longer return a value.

5249
Gregory P. Smithae91d092009-03-02 05:13:57 +00005250- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
5251
Georg Brandlba83f822010-03-14 09:50:54 +00005252- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
5253 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00005254
Matthias Klose91a3b9e2009-04-05 21:19:13 +00005255- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
5256 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00005257
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00005258- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
5259 returned them on 64bit platforms.
5260
Walter Dörwalded960ac2009-05-03 22:36:33 +00005261- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5262 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5263 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5264 of using the replace error handler in PyUnicode_DecodeUTF8().
5265
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005266- Issue #3739: The unicode-internal encoder now reports the number of characters
5267 consumed like any other encoder (instead of the number of bytes).
5268
Georg Brandlba83f822010-03-14 09:50:54 +00005269- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5270 allocator will be automatically disabled when running under Valgrind. This
5271 gives improved memory leak detection when running under Valgrind, while taking
5272 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00005297- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
5298 ownership when the group is not forced, because the group may be different
5299 from the user's group and inherit from its container when the test is run.

5343 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00005344 __main__.py file. This allows applications that run other Python scripts to

6442 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6443 neither __int__ nor __long__, TypeError used to be raised (with a

6641
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006642- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6643 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6644 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6645 ``printf`` function, whereas PyString_FromFormat has an independent
6646 implementation and uses "%zd" on all platforms for size_t values.
6647 This makes a difference on win64, where ``printf`` needs "%Id" to display
6648 64bit values.

6654 object; previously an int would be returned for small values. the __long__
6655 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006665 was correctly parsed but parsing of subsequent arguments failed.
6666
Vinay Sajip35e3b032008-09-01 14:33:59 +00006667- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006668 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6669 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6670 when given a tuple of classes as second argument, were looking up
6671 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6672 type object.

6818
Guido van Rossumf8402962008-08-20 15:01:50 +00006819- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6820 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6821 extensions do not automatically benefit from the class attribute
6822 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6823 to their tp_flags field if they care. This is a backwards
6824 compatibility feature; in 3.0, all types will use the cache by
6825 default.
6826
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006827- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +00006840- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6841 ValueError consistently across platforms.
6842
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006843- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6844 (64bit Unix, for example), unichr() would truncate its argument and return
6845 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006849- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6850 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6851
Antoine Pitrou92f82162008-07-25 22:22:08 +00006852- Issue #1819: function calls with several named parameters are now on
6853 average 35% faster (as measured by pybench).
6854
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006855- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6856 the python debugger steps into a class statement: the free variables (local
6857 variables defined in an outer scope) would be deleted from the outer scope.
6858
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006859- Issue #2620: Overflow checking when allocating or reallocating memory
6860 was not always being done properly in some python types and extension
6861 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6862 all been updated to perform better checks and places in the code that
6863 would previously leak memory on the error path when such an allocation
6864 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00006871- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6872 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6873
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006874- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6875 version reported by these tools does not necessarily follow the python
6876 version numbering scheme, so the module is less strict when parsing it.
6877
Nick Coghlanf70385a2008-08-18 12:42:46 +00006878- Issue #2235: Added Py3k warnings for types which will become unhashable
6879 under the stricter __hash__ inheritance rules in 3.0. Several types
6880 which did not meet the rules for hash invariants and were already
6881 unhashable in 3.0 have now been explicitly flagged as unhashable in
6882 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,

Brett Cannonbf3157b2008-08-14 05:00:03 +00006916- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6917 since mimetools itself is deprecated. Because modules are cached, all
6918 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6919

6932 to _sre.compile() will now be rejected. This should not affect anybody
6933 since the re.compile() function never generates invalid re-bytecode.
6934
Skip Montanaroa032bf42008-08-08 22:52:51 +00006935- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

6937 it wasn't initialized during instantiation.
6938
Brett Cannon3aa2a492008-08-06 22:28:09 +00006939- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6940 the reload() built-in has been removed.
6941
Brett Cannon7e30b672008-08-04 21:52:25 +00006942- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00006954 asking for a specific length. This problem only affected files opened
6955 using the new "io" module, not the built-in open() function.

6981 file name rather than a ZipInfo instance, so files are extracted with
6982 mode 0600 rather than 000 under Unix.
6983
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006984- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6985 argument in python 2.5, this broke code that subclassed Popen to include its

6997 interaction with the tp_hash slot (added in 2.6b2) are now documented
6998
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006999- Issue #643841: The language reference now provides more detailed
7000 coverage of the lookup process for special methods. The disclaimers
7001 regarding lack of coverage of new-style classes have also been
7002 removed, since the coverage is now fairly reasonable.

7006================================
7007
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007008*Release date: 17-Jul-2008*
7009
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007010Core and Builtins
7011-----------------
7012
Georg Brandl3e483f62008-07-16 22:57:41 +00007013- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7014 its methods now allow for items objects that can be converted to
7015 an integer using operator.index().
7016
Mark Dickinson64b7e502008-07-16 09:40:03 +00007017- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7018 produced a ValueError instead of giving the correct float.
7019
Eric Smitha5fa5a22008-07-16 00:11:49 +00007020- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7021 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7022
Mark Dickinson7103aa42008-07-15 19:08:33 +00007023- Issue #3008: the float type has a new instance method 'float.hex'
7024 and a new class method 'float.fromhex' to convert floating-point
7025 numbers to and from hexadecimal strings, respectively.
7026
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007027- Issue #2235: __hash__ is once again inherited by default. To allow
7028 collections.Hashable to remain meaningful in the presence of the
7029 default hash implementation (object.__hash__), it is now possible
7030 to explicit block inheritance of hash by setting __hash__=None at
7031 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7032 level.
7033
Nick Coghlanb028f502008-07-13 14:52:36 +00007034- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7035 the parent module cannot be found while performing an absolute import.
7036 This means that an incorrectly defined __package__ attribute will
7037 now only prevent relative imports in that module rather than causing
7038 all imports from that module to fail.
7039
Nick Coghlan14ff9942008-07-08 14:21:42 +00007040- Issue #2517: Allow unicode messages in Exceptions again by correctly
7041 bypassing the instance dictionary when looking up __unicode__ on
7042 new-style classes.
7043
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007044- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7045 set to a custom object whose write() method happens to install
7046 another file in sys.stdout.
7047
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007048- Issue #3088: Corrected a race condition in classes derived from
7049 threading.local: the first member set by a thread could be saved in
7050 another thread's dictionary.
7051
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007052- Issue #3004: Minor change to slice.indices(): the start and stop
7053 arguments are now treated identically, making the behaviour easier
7054 to describe and understand. For example, slice(None, -10,
7055 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7056 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7057 10, -1).
7058
Georg Brandl278fc502008-07-19 12:46:12 +00007059- Issue #3219: Calling a function with repeated keyword arguments,
7060 f(a=2, a=23), would not cause a syntax error. This was a regression
7061 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007062
Georg Brandl278fc502008-07-19 12:46:12 +00007063- Issue #2862: Make int and float freelist management consistent with
7064 other freelists. Changes their CompactFreeList apis into
7065 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007066

7069
Thomas Heller57adf222008-08-14 19:10:48 +00007070- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7071 api functions without holding the GIL, which could lead to a fatal
7072 error when they failed.
7073
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007074- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7083 ForkingPickler.register() to resolve conflict with ctypes.
7084
Vinay Sajip51e65192008-07-18 09:01:10 +00007085- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00007087- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7088 a valid dlerror() message.
7089
Thomas Heller2bad6572008-07-15 17:19:50 +00007090- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7091 incomplete structure was created.
7092

7096
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007097- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007098
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007099- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7100 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007101 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007102 content-length. The problem had been corrected in the 2.4 branch, but never
7103 merged into trunk.
7104
Georg Brandle78fbcc2008-07-05 10:13:36 +00007105- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007116 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00007117
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007118- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007509 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007510
7511 This is controlled by the configure argument ``--with-universal-archs``:
7512
7513 - ``--with-universal-archs=all``: install 4-way universal
7514
7515 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7516
7517 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7518
7519 This option should be used in combination with ``--enable-universalsdk=``.
7520
7521 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 +00007570- Issue #1631171: Re-implement the 'warnings' module in C (the
7571 original Python code has been kept as backup). This will allow for
7572 using the 'warning's machinery in such places as the parser where
7573 use of pure Python code is not possible. Both the ``showarning()``
7574 and ``formatwarning()`` gain an optional 'line' argument which is
7575 not called by default for backwards-compatibility reasons. Setting
7576 ``warnings.showwarning()`` to an implementation that lacks support
7577 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007640- Issue #2550: The approach used by client/server code for obtaining
7641 ports to listen on in network-oriented tests has been refined in an
7642 effort to facilitate running multiple instances of the entire
7643 regression test suite in parallel without issue.
7644 test_support.bind_port() has been fixed such that it will always
7645 return a unique port -- which wasn't always the case with the
7646 previous implementation, especially if socket options had been set
7647 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7648 new implementation of bind_port() will actually raise an exception
7649 if it is passed an AF_INET/SOCK_STREAM socket with either the
7650 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7651 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7652 the socket it's been passed. This currently only applies to
7653 Windows. This option prevents any other sockets from binding to the
7654 host/port we've bound to, thus removing the possibility of the
7655 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7656 when a second SOCK_STREAM socket binds and accepts to a host/port
7657 that's already been bound by another socket. The optional preferred
7658 port parameter to bind_port() has been removed. Under no
7659 circumstances should tests be hard coding ports!
7660
7661 test_support.find_unused_port() has also been introduced, which will
7662 pass a temporary socket object to bind_port() in order to obtain an
7663 unused port. The temporary socket object is then closed and
7664 deleted, and the port is returned. This method should only be used
7665 for obtaining an unused port in order to pass to an external program
7666 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7667 a parameter to a server-oriented class that doesn't give you direct
7668 access to the underlying socket used.
7669
7670 Finally, test_support.HOST has been introduced, which should be used
7671 for the host argument of any relevant socket calls (i.e. bind and
7672 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007673
7674 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007675 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007676 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7677 test_asynchat and test_socket_ssl.
7678
Georg Brandl3ee81df2008-05-17 18:14:43 +00007679 It is now possible for multiple instances of the regression test
7680 suite to run in parallel without issue.

7947-----------------
7948
Fred Drakea8ee94b2008-03-01 02:45:07 +00007949- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007950 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007951
Georg Brandlad61bc82008-02-23 15:11:18 +00007952- Issue #2067: file.__exit__() now calls subclasses' close() method.
7953
7954- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007955
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007956- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007957 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007958
Eric Smitha73fbe72008-02-23 03:09:44 +00007959- Added the future_builtins module, which contains hex() and oct().
7960 These are the PEP 3127 version of these functions, designed to be
7961 compatible with the hex() and oct() builtins from Python 3.0. They
7962 differ slightly in their output formats from the existing, unchanged
7963 Python 2.6 builtins. The expected usage of the future_builtins
7964 module is:
7965 from future_builtins import hex, oct
7966
Eric Smith7ef40bf2008-02-20 23:34:22 +00007967- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7968 exponents for exponents with absolute value < 100. Follows C99
7969 standard. This is a change on Windows, which would use 3 digits.
7970 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7971 so that any alterations it does to the resulting string will be
7972 available in stringlib/formatter.h (for float.__format__).
7973
Eric Smith5a3c1352008-02-19 13:21:56 +00007974- Implemented PEP 3101, Advanced String Formatting. This adds a new
7975 builtin format(); a format() method for str and unicode; a
7976 __format__() method to object, str, unicode, int, long, float, and
7977 datetime; the class string.Formatter; and the C API
7978 PyObject_Format().
7979
Georg Brandl3ee81df2008-05-17 18:14:43 +00007980- Fixed several potential crashes, all caused by specially crafted
7981 __del__ methods exploiting objects in temporarily inconsistent
7982 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007983
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007984- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007985 prevent a possible crash: an Abstract Base Class would try to access
7986 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007987
Georg Brandl3ee81df2008-05-17 18:14:43 +00007988- Fixed repr() and str() of complex numbers with infinity or nan as
7989 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007990
Georg Brandl3ee81df2008-05-17 18:14:43 +00007991- Clear all free lists during a gc.collect() of the highest generation
7992 in order to allow pymalloc to free more arenas. Python may give back
7993 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007994
Georg Brandl3ee81df2008-05-17 18:14:43 +00007995- Issue #2045: Fix an infinite recursion triggered when printing a
7996 subclass of collections.defaultdict, if its default_factory is set
7997 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007998
Christian Heimesf75dbef2008-02-08 00:11:31 +00007999- Fixed a minor memory leak in dictobject.c. The content of the free
8000 list was not freed on interpreter shutdown.
8001
Georg Brandl21e99f42010-03-07 15:23:59 +00008002- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008003 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008004
Georg Brandl3ee81df2008-05-17 18:14:43 +00008005- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8006 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008007 to compact the internal free lists of pre-allocted ints and floats.
8008
Georg Brandl3ee81df2008-05-17 18:14:43 +00008009- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8010 calls. Python expected the return type int but the fork familie
8011 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008012
Georg Brandl3ee81df2008-05-17 18:14:43 +00008013- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8014 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008015
Georg Brandl3ee81df2008-05-17 18:14:43 +00008016- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8017 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008018
Georg Brandl3ee81df2008-05-17 18:14:43 +00008019- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8020 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008021
Georg Brandl3ee81df2008-05-17 18:14:43 +00008022- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8023 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008024
Georg Brandl3ee81df2008-05-17 18:14:43 +00008025- Patch #1473257: generator objects gain a gi_code attribute. This is
8026 the same object as the func_code attribute of the function that
8027 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008028
Georg Brandl3ee81df2008-05-17 18:14:43 +00008029- Issue #1920: "while 0" statements were completely removed by the
8030 compiler, even in the presence of an "else" clause, which is
8031 supposed to be run when the condition is false. Now the compiler
8032 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008033
Guido van Rossumeead05f2008-01-24 18:21:02 +00008034- A few crashers fixed: weakref_in_del.py (issue #1377858);
8035 loosing_dict_ref.py (issue #1303614, test67.py);
8036 borrowed_ref_[34].py (not in tracker).
8037
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008038- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008039 suppressed while an extension is loaded by calling SetErrorMode in
8040 dynload_win.c. The error is still reported properly.
8041
Georg Brandl3ee81df2008-05-17 18:14:43 +00008042- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008043 several extension methods and modules do not work without unicode
8044 support.
8045
Georg Brandl26543b12008-01-21 18:36:51 +00008046- Issue #1882: when compiling code from a string, encoding cookies in the
8047 second line of code were not always recognized correctly.
8048
Georg Brandl14404b62008-01-19 19:27:05 +00008049- Issue #1679: "0x" was taken as a valid integer literal.
8050
Georg Brandl6caad7d2008-01-26 14:19:22 +00008051- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008052 added.
8053
Christian Heimesc94e2b52008-01-14 04:13:37 +00008054- sys.float_info / PyFloat_GetInfo: The floating point information
8055 object was converted from a dict to a specialized structseq object.
8056
Georg Brandl3ee81df2008-05-17 18:14:43 +00008057- Patch #1816: Added sys.flags structseq. It exposes the status of
8058 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008059
Georg Brandl3ee81df2008-05-17 18:14:43 +00008060- Objects/structseq.c: Implemented new structseq representation. The
8061 patch makes structseqs (e.g. the return value of os.stat) more
8062 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008063
Georg Brandl3ee81df2008-05-17 18:14:43 +00008064- Patch #1700288: added a type attribute cache that caches method
8065 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008066
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008067- Bug #1776: __import__() no longer accepts filenames on any platform.
8068 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008069
Georg Brandlaed6c662008-01-07 17:25:53 +00008070- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8071
Georg Brandl3ee81df2008-05-17 18:14:43 +00008072- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8073 envvar and sys.dont_write_bytecode attribute. All these can be set
8074 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008075
Georg Brandl3ee81df2008-05-17 18:14:43 +00008076- Improve some exception messages when Windows fails to load an
8077 extension module. Now we get for example '%1 is not a valid Win32
8078 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008079
Georg Brandl3ee81df2008-05-17 18:14:43 +00008080- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008082- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8083 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008084
Christian Heimes0a8143f2007-12-18 23:22:54 +00008085- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008086 and INF. float("nan"), float("inf") and float("-inf") now work on
8087 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008088
Georg Brandl3ee81df2008-05-17 18:14:43 +00008089- Compiler now generates simpler and faster code for dictionary
8090 literals. The oparg for BUILD_MAP now indicates an estimated
8091 dictionary size. There is a new opcode, STORE_MAP, for adding
8092 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008093
Georg Brandl3ee81df2008-05-17 18:14:43 +00008094- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008099- Issue #1538: Avoid copying string in split/rsplit if the split char
8100 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008101
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008102- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008103 SystemError.
8104
Nick Coghlanef01d822007-12-03 12:55:17 +00008105- PEP 366: Allow explicit relative imports when executing modules
8106 inside packages with the -m switch via a new module level
8107 __package__ attribute.
8108
Georg Brandl3ee81df2008-05-17 18:14:43 +00008109- Issue #1402: Fix a crash on exit, when another thread is still
8110 running, and if the deallocation of its frames somehow calls the
8111 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008112

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008116 attribute of an empty cell object.
8117
Georg Brandl3ee81df2008-05-17 18:14:43 +00008118- Issue #1460: The utf-7 incremental decoder did not accept truncated
8119 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00008120
Georg Brandl3ee81df2008-05-17 18:14:43 +00008121- Patch #1739468: Directories and zipfiles containing a __main__.py
8122 file can now be directly executed by passing their name to the
8123 interpreter. The directory/zipfile is automatically inserted as the
8124 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008125
Georg Brandl3ee81df2008-05-17 18:14:43 +00008126- Issue #1265: Fix a problem with sys.settrace, if the tracing
8127 function uses a generator expression when at the same time the
8128 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008129
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008130- sets and frozensets now have an isdisjoint() method.
8131
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008132- optimize the performance of builtin.sum().
8133
Neal Norwitz44f326e2007-10-05 05:29:17 +00008134- Fix warnings found by the new version of the Coverity checker.
8135
Georg Brandl21e99f42010-03-07 15:23:59 +00008136- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008137 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8138 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008139
Georg Brandl3ee81df2008-05-17 18:14:43 +00008140- Issue #1686386: Tuple's tp_repr did not take into account the
8141 possibility of having a self-referential tuple, which is possible
8142 from C code. Nor did object's tp_str consider that a type's tp_str
8143 could do something that could lead to an inifinite recursion.
8144 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8145 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008146
Georg Brandl3ee81df2008-05-17 18:14:43 +00008147- Issue #1164: It was possible to trigger deadlock when using the
8148 'print' statement to write to a file since the GIL was not released
8149 as needed. Now PyObject_Print() does the right thing along with
8150 various tp_print implementations of the built-in types and those in
8151 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008152
Georg Brandl3ee81df2008-05-17 18:14:43 +00008153- Issue #1147: Exceptions were directly allowing string exceptions in
8154 their throw() method even though string exceptions no longer
8155 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008156
Georg Brandl3ee81df2008-05-17 18:14:43 +00008157- Issue #1096: Prevent a segfault from getting the repr of a very
8158 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008159
Brett Cannon1e534b52007-09-07 04:18:30 +00008160- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008161 PyObject_Call() never calling back out to Python code to trigger
8162 recursion depth updates/checks. Required the creation of a static
8163 RuntimeError instance in case normalizing an exception put the
8164 recursion check value past its limit. Fixes crashers
8165 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008166
Georg Brandl3ee81df2008-05-17 18:14:43 +00008167- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008180- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008181 __*__ attributes. (Some already existed, e.g., __doc__ and
8182 __name__.)

Georg Brandl3ee81df2008-05-17 18:14:43 +00008191 "except E as target:". This is to provide forwards compatibility
8192 with Python 3.0.

8212
Guido van Rossum143b5642007-03-23 04:58:42 +00008213- Bug #1683368: The object.__init__() and object.__new__() methods are
8214 now stricter in rejecting excess arguments. The only time when
8215 either allows excess arguments is when it is not overridden and the
8216 other one is. For backwards compatibility, when both are
8217 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008218 warning later). Also, type.__init__() insists on the same signature
8219 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008221- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8222 object to complex using its __complex__() method before falling back
8223 to the __float__() method. Therefore, the functions in the cmath
8224 module now can operate on objects that define a __complex__()
8225 method.

8242
Georg Brandl7b9c5552007-03-12 14:30:05 +00008243- Bug #1678647: write a newline after printing an exception in any
8244 case, even when converting the value to a string failed.
8245
Georg Brandl871f1bc2007-03-12 13:17:36 +00008246- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008247 its argument, if it exists. If not, it will work like before. This
8248 allows customizing the output of dir() in the presence of a
8249 __getattr__().

8259 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008260
Georg Brandlaa2321b2007-03-07 00:40:28 +00008261- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008262 makes the filenames the warning module prints much more sensible
8263 when a PYTHONSTARTUP file is used.

8277 sq_ass_slice instead of the sq_slice slot.
8278
Georg Brandl3ee81df2008-05-17 18:14:43 +00008279- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00008904- unittest now verifies more of its assumptions. In particular,
8905 TestCase and TestSuite subclasses (not instances) are no longer
8906 accepted in TestSuite.addTest(). This should cause no
8907 incompatibility since it never made sense with ordinary subclasses
8908 -- the failure just occurred later, with a more cumbersome
8909 exception.

9182 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009183
Georg Brandl3ee81df2008-05-17 18:14:43 +00009184- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9185 with RFC 3207 and forgets any knowledge obtained from the server not
9186 obtained from the TLS negotiation itself. Patch contributed by Bill
9187 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009188
Georg Brandl3ee81df2008-05-17 18:14:43 +00009189- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009190 that the SMTP.starttls() caller no longer needs to call ehlo()
9191 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009192 does not claim to support starttls. Adds the
9193 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9274 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9275 silently miscode subclasses of those types. Now, it raises a
9276 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009277

Georg Brandl3ee81df2008-05-17 18:14:43 +00009292 time so that opening a database previously created with the DB_DUP
9293 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9294 opens. Specifically: dictionary assignment to a DB object will
9295 replace all values for a given key when the database allows
9296 duplicate values. DB users should use DB.put(k, v) when they want
9297 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009298

9304 characters with ASCII value less than 32. Also, it correctly quotes
9305 dots only if they occur on a single line, as opposed to the previous
9306 behavior of quoting dots if they are the second character of any
9307 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009308

Georg Brandl3ee81df2008-05-17 18:14:43 +00009642- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9643 to ``PyTuple_SetItem``, it can be used to populate a brand new
9644 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009645
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009646- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009647
Georg Brandl3ee81df2008-05-17 18:14:43 +00009648- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9649 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9650 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009651
9652- Patch #1720595: add T_BOOL to the range of structmember types.
9653
9654- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9655 ``PyFloat_GetInfo()`` to the float API.
9656
Georg Brandl3ee81df2008-05-17 18:14:43 +00009657- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9658 of w# format code incorrectly truncated the length to an int, even
9659 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9660 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009661
Georg Brandl3ee81df2008-05-17 18:14:43 +00009662- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9663 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009665- PEP 3123: Provide forward compatibility with Python 3.0, while
9666 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9667 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009668
Georg Brandl3ee81df2008-05-17 18:14:43 +00009669- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9670 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009671
9672- Patch #1733960: Allow T_LONGLONG to accept ints.
9673
9674- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9675
Christian Heimes000a0742008-01-03 22:16:32 +00009676- Added a new API function ``PyImport_ImportModuleNoBlock``.
9677
Georg Brandl6caad7d2008-01-26 14:19:22 +00009678- Bug #1637022: Prefix AST symbols with _Py_.
9679
9680- Fix some leftovers from the conversion from int to Py_ssize_t
9681 (relevant to strings and sequences of more than 2**31 items).
9682
9683- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9684 outside of pystate.c and should not be necessary.
9685
Georg Brandl3ee81df2008-05-17 18:14:43 +00009686- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9687 absolute imports. In earlier versions they might have used relative
9688 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009689
Georg Brandl3ee81df2008-05-17 18:14:43 +00009690- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9691 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009692
Georg Brandl3ee81df2008-05-17 18:14:43 +00009693- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
9694 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009699- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9700 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9701 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9702 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009703
Georg Brandl3ee81df2008-05-17 18:14:43 +00009704- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00009716- Removed the macfs module. It had been deprecated since Python 2.5.
9717 This lead to the deprecation of macostools.touched() as it relied
9718 solely on macfs and was a no-op under OS X.
