Ned Deily18fae3f2013-01-31 01:24:55 -08001439- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1440 In particular, fix extension module build failures when trying to use
1441 32-bit-only installer Pythons on systems with Xcode 4 (currently
1442 OS X 10.8, 10.7, and optionally 10.6).
1443 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1444 * Since Xcode 4 removes ppc support, extension module builds now
1445 check for ppc compiler support and by default remove ppc and
1446 ppc64 archs when they are not available.
1447 * Extension module builds now revert to using system installed
1448 headers and libs (/usr and /System/Library) if the SDK used
1449 to build the interpreter is not installed or has moved.
1450 * Try to avoid building extension modules with deprecated

1802
Mark Dickinsondbbed042011-09-19 16:38:08 +01001803- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1804 int.__pow__. These overflow checks were causing int.__pow__ to produce
1805 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001806 compiler optimizing the check away. Also fix similar overflow checks
1807 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1808 bugs caused test failures with recent versions of Clang.

1821 and its type get caught in a reference cycle, and the instance's

Florent Xiclunac2279652012-02-12 14:49:03 +01001876- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001877 has left two versions of customize_compiler, the original in
1878 distutils.sysconfig and another copy in distutils.ccompiler, with some

1881 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01001883- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1884 Distutils-based packages with C extension modules may fail because
1885 Apple has removed gcc-4.2, the version used to build python.org
1886 64-bit/32-bit Pythons. If the user does not explicitly override
1887 the default C compiler by setting the CC environment variable,
1888 Distutils will now attempt to compile extension modules with clang
1889 if gcc-4.2 is required but not found. Also as a convenience, if
1890 the user does explicitly set CC, substitute its value as the default
1891 compiler in the Distutils LDSHARED configuration variable for OS X.
1892 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1893 SDK, neither of which are available in Xcode 4. This change does not
1894 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002144- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2145 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2146 interpreter process. This could cause failures in non-Distutils subprocesses
2147 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002148 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002149 deployment target only in the environment of each build subprocess. It is
2150 still possible to globally override the default by setting
2151 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2152 greater or equal to the default value, the value with which the interpreter
2153 was built.

2180
Barry Warsawc5643282011-07-19 17:06:30 -04002181- sys.setcheckinterval() now updates the current ticker count as well as
2182 updating the check interval, so if the user decreases the check interval,
2183 the ticker doesn't have to wind down to zero from the old starting point
2184 before the new interval takes effect. And if the user increases the
2185 interval, it makes sure the new limit takes effect right away rather have an
2186 early task switch before recognizing the new interval.

3167 This prevents user-created self-referencing ordered dictionaries from
3168 becoming permanently uncollectable GC garbage. The downside is that
3169 removing __del__ means that the internal doubly-linked list has to wait for
3170 GC collection rather than freeing memory immediately when the refcnt drops

3628
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003629- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3630 start byte and the continuation byte(s) are now considered invalid, instead
3631 of the number of bytes specified by the start byte.
3632 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3633 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3634 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3635 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003643- Issue #8748: Fix two issues with comparisons between complex and integer
3644 objects. (1) The comparison could incorrectly return True in some cases
3645 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3646 (2) The comparison raised an OverflowError for large integers, leading
3647 to unpredictable exceptions when combining integers and complex objects
3648 in sets or dicts.
3649
Mark Dickinson81336372010-05-30 12:12:25 +00003650- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00003787- Issue #1533: Fix inconsistency in range function argument processing: any
3788 non-float non-integer argument is now converted to an integer (if possible)
3789 using its __int__ method. Previously, only small arguments were treated this
3790 way; larger arguments (those whose __int__ was outside the range of a C long)
3791 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00003799 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00003800 benefit compared to the dynamic memory allocation fallback. Patch by

3826 messages when accessing undefined class attributes because of the cheap
3827 inheritance with the underlying socket object. The cheap inheritance has been
3828 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00003841- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3842 operation raises multiple signals and more than one of those signals is
3843 trapped, the specification determines the order in which the signals should be
3844 handled. In many cases this order wasn't being followed, leading to the wrong
3845 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00003846

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004011
4012Core and Builtins
4013-----------------
4014
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004015- Issue #7301: Add environment variable $PYTHONWARNINGS.
4016
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004017- Issue #8329: Don't return the same lists from select.select when no fds are
4018 changed.
4019
Georg Brandlfee0f442010-05-22 21:26:21 +00004020- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004021 on 64-bit machines. The shift count for either left or right shift is
4022 permitted to be up to sys.maxsize.
4023
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004024- Ensure that tokenization of identifiers is not affected by locale.
4025
Georg Brandlfee0f442010-05-22 21:26:21 +00004026- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004027
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004028- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4029
Georg Brandlfee0f442010-05-22 21:26:21 +00004030- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4031 with a non-empty format string. This is an effort to future-proof user
4032 code. If a derived class does not currently implement __format__ but later
4033 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004034 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004035 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004036
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004037- Issue #8268: Old-style classes (not just instances) now support weak
4038 references.
4039
Georg Brandlfee0f442010-05-22 21:26:21 +00004040- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4041 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004042
Victor Stinnerc7790ed2010-03-22 12:36:28 +00004043- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00004044
Benjamin Peterson96545892010-03-21 20:21:00 +00004045- Issue #6474: Make error message from passing an inadequate number of keyword
4046 arguments to a function correct.
4047
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004048- Issue #8164: Don't allow lambda functions to have a docstring.
4049
Victor Stinner66644262010-03-10 22:30:19 +00004050- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004051 (SIGINT). If an error occurs while importing the site module, the error is
4052 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004053 module.
4054
Collin Winter001a3952010-03-18 21:54:01 +00004055- Code objects now support weak references.

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004057Library
4058-------
4059
R. David Murray661303f2010-04-13 20:57:40 +00004060- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
4061
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004062- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00004063 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4064 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004065
Benjamin Peterson76a23c12010-04-04 23:23:22 +00004066- Issue #8310: Allow dis to examine new style classes.
4067
Georg Brandlfee0f442010-05-22 21:26:21 +00004068- Issue #8257: The Decimal construct now accepts a float instance directly,
4069 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004070
4071 >>> Decimal(1.1)
4072 Decimal('1.100000000000000088817841970012523233890533447265625')
4073
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004074- collections.Counter() now supports a subtract() method.
4075
Georg Brandlfee0f442010-05-22 21:26:21 +00004076- The functools module now has a total_ordering() class decorator to simplify
4077 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004078
Georg Brandlfee0f442010-05-22 21:26:21 +00004079- The functools module also adds cmp_to_key() as a tool to transition old-style
4080 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004081
Georg Brandlfee0f442010-05-22 21:26:21 +00004082- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4083 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004084
Georg Brandlfee0f442010-05-22 21:26:21 +00004085- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4086 InvalidOperation instead of returning False. (Comparisons involving a quiet
4087 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4088 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004089
Georg Brandlfee0f442010-05-22 21:26:21 +00004090- Issue #2531: Comparison operations between floats and Decimal instances now
4091 return a result based on the numeric values of the operands; previously they
4092 returned an arbitrary result based on the relative ordering of id(float) and
4093 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004094
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004095- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004096 argument `-` which tells it to read files to compile from stdin. Each line is
4097 read on demand and the named file is compiled immediately. (Original patch by
4098 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004099
Georg Brandlfee0f442010-05-22 21:26:21 +00004100- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4101 function like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +00004102
Florent Xicluna58b65662010-03-30 16:29:03 +00004103- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4104 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004105 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004106
Georg Brandlfee0f442010-05-22 21:26:21 +00004107- Comparisons using one of <, <=, >, >= between a complex instance and a
4108 Fractions instance now raise TypeError instead of returning True/False. This
4109 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4110 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004111
Michael Foorde6410c52010-03-29 20:04:23 +00004112- Addition of ``WeakSet`` to the ``weakref`` module.

4120
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004121- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004122 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4123 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004124
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004125- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4126 deprecated.
4127
Georg Brandlfee0f442010-05-22 21:26:21 +00004128- Issue #7860: platform.uname now reports the correct 'machine' type when Python
4129 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00004130

4135 existing at the same time, causing a Unicode error when configuration code
4136 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00004137
Georg Brandlfee0f442010-05-22 21:26:21 +00004138- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
4139 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00004140
Antoine Pitroueee91cd2010-03-26 19:27:16 +00004141- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
4142 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4143 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00004144
Florent Xiclunacf82fa62010-03-21 12:27:20 +00004145- Issue #8179: Fix macpath.realpath() on a non-existing path.

4159 locale.
Matthias Klose358e7ff2010-03-15 13:42:23 +00004160
Georg Brandlfee0f442010-05-22 21:26:21 +00004161- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set

Vinay Sajipecfa08f2010-03-12 09:16:10 +00004165- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00004166 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4167 log file to compute the next rollover time. If the log file does not exist,
4168 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004169
Georg Brandlba83f822010-03-14 09:50:54 +00004170- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

4177
Georg Brandlba83f822010-03-14 09:50:54 +00004178- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4179 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4180 This is a behavior change, so email's minor version number is now bumped, to
4181 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004209- Issue #8300: When passing a non-integer argument to struct.pack with any
4210 integer format code, struct.pack first attempts to convert the non-integer
4211 using its __index__ method. If that method is non-existent or raises
4212 TypeError it goes on to try the __int__ method, as described below.
4213
Georg Brandlba83f822010-03-14 09:50:54 +00004214- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4215 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4216 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004217 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4218 inconsistent: __int__ was used for some integer codes but not for others, and
4219 the set of integer codes for which it was used differed between native packing
4220 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004472- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4473 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4474 returning NULL. The macro now returns a statically allocated empty string

4625-----------------
4626
Georg Brandlba83f822010-03-14 09:50:54 +00004627- The ``__complex__()`` method is now looked up on the class of instances to
4628 make it consistent with other special methods.

4632
Mark Dickinson1b34d252010-01-01 17:27:30 +00004633- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004634 DeprecationWarning when passed a float argument where an integer was expected.
4635 These functions and methods now raise TypeError instead. The majority of the
4636 effects of this change are in the extension modules, but some core functions
4637 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4638 and many unicode/str methods.

4650
Georg Brandlba83f822010-03-14 09:50:54 +00004651- Issue #1811: Improve accuracy and cross-platform consistency for true division
4652 of integers: the result of a/b is now correctly rounded for ints a and b (at
4653 least on IEEE 754 platforms), and in particular does not depend on the
4654 internal representation of a long.

4662
Georg Brandlba83f822010-03-14 09:50:54 +00004663 These executables now work properly with the arch(1) command: ``arch -ppc
4664 python`` will start a universal binary version of python in PPC mode (unlike

4804 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004805

4807 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00004820- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4821 decimal string that's guaranteed to round back to x under correct rounding
4822 (with round-half-to-even rounding mode). Previously it gave a string based on
4823 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4824 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4825 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004826
Georg Brandlba83f822010-03-14 09:50:54 +00004827- Issue #7117: On almost all platforms: float-to-string and string-to-float
4828 conversions within Python are now correctly rounded. Places these conversions
4829 occur include: str for floats and complex numbers; the float and complex
4830 constructors; old-style and new-style numeric formatting; serialization and
4831 deserialization of floats and complex numbers using marshal, pickle and json;
4832 parsing of float and imaginary literals in Python code; Decimal-to-float
4833 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004834
Georg Brandlba83f822010-03-14 09:50:54 +00004835 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4836 providing correctly-rounded strtod and dtoa C functions. This code is
4837 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4838 the C compiler. There may be a small number of platforms on which correct
4839 operation of this code cannot be guaranteed, so the code is not used: notably,
4840 this applies to platforms where the C double format is not IEEE 754 binary64,
4841 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4842 and Python's configure script is unable to determine how to change the FPU
4843 precision. On these platforms conversions use the platform strtod and dtoa,
4844 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004846- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4847 uses the correctly-rounded string <-> float conversions described above (when
4848 available), and so produces correctly rounded results that will display nicely
4849 under the float repr. There are two related small changes: (1) round now
4850 accepts any class with an ``__index__()`` method for its second argument (but
4851 no longer accepts floats for the second argument), and (2) an excessively
4852 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4853 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004996 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4997 (2) parsing of strings representing infinities and nans was locale aware; and
4998 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005000- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5001 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5002 but with at least one decimal point and with a default precision
5003 of 12. Previously, the behavior the same but with a default precision of 6.
5004 This more closely matches ``str()``, and reduces surprises when adding
5005 alignment flags to the empty presentation type. This also affects the new
5006 complex.__format__ in the same way.
5007
5008- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00005184- Issue #4597: Fixed exception handling when the __exit__ function of a context
5185 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00005186

Georg Brandlba83f822010-03-14 09:50:54 +00005189- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5190 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5191 instances. On a typical machine this saves 3 bytes of memory (on average) per
5192 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005194- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
5195 interpreter to abort ("Fatal Python error: Could not reset the stack!")
5196 instead of throwing a MemoryError.
5197
Georg Brandlba83f822010-03-14 09:50:54 +00005198- Issue #3689: The list reversed iterator now supports __length_hint__ instead
5199 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00005200
Benjamin Petersonc078f922008-11-21 22:27:24 +00005201- Issue #4367: Python would segfault during compiling when the unicodedata
5202 module couldn't be imported and \N escapes were present.
5203
Georg Brandlba83f822010-03-14 09:50:54 +00005204- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5205 file objects with closefd=False. The file descriptor is still kept open but
5206 the file object behaves like a closed file. The ``FileIO`` object also got a
5207 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00005208
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005209- Issue #4348: Some bytearray methods returned that didn't cause any change to
5210 the bytearray, returned the same bytearray instead of a copy.
5211
Georg Brandlba83f822010-03-14 09:50:54 +00005212- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

5215
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00005216- Issue #4048: The parser module now correctly validates relative imports.
5217
Benjamin Petersondcee09d2008-10-31 02:16:05 +00005218- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
5219 exec statement.
5220
Georg Brandlba83f822010-03-14 09:50:54 +00005221- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
5222 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00005223
Benjamin Petersonbdca9422008-10-26 20:21:13 +00005224- Issue #4209: Enabling unicode_literals and the print_function in the same
5225 __future__ import didn't work.
5226
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005227- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005228 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005229
Georg Brandlba83f822010-03-14 09:50:54 +00005230- On windows, ``os.chdir()`` given unicode was not working if
5231 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5232 this code path is really executed because I cannot move to such directory on
5233 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005234
Georg Brandlba83f822010-03-14 09:50:54 +00005235- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5236 element is temporarily replaced with an equivalent frozenset. But the
5237 eventual KeyError would always report the empty ``frozenset()`` as the missing
5238 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00005239
Georg Brandlba83f822010-03-14 09:50:54 +00005240- Issue #4509: Various issues surrounding resize of bytearray objects to which
5241 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00005242
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00005243- Issue #4748: Lambda generators no longer return a value.

5246
Gregory P. Smithae91d092009-03-02 05:13:57 +00005247- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
5248
Georg Brandlba83f822010-03-14 09:50:54 +00005249- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
5250 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00005251
Matthias Klose91a3b9e2009-04-05 21:19:13 +00005252- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
5253 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00005254
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00005255- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
5256 returned them on 64bit platforms.
5257
Walter Dörwalded960ac2009-05-03 22:36:33 +00005258- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5259 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5260 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5261 of using the replace error handler in PyUnicode_DecodeUTF8().
5262
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005263- Issue #3739: The unicode-internal encoder now reports the number of characters
5264 consumed like any other encoder (instead of the number of bytes).
5265
Georg Brandlba83f822010-03-14 09:50:54 +00005266- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5267 allocator will be automatically disabled when running under Valgrind. This
5268 gives improved memory leak detection when running under Valgrind, while taking
5269 advantage of pymalloc at other times.

5296 from the user's group and inherit from its container when the test is run.

6439 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6440 neither __int__ nor __long__, TypeError used to be raised (with a

6638
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006639- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6640 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6641 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6642 ``printf`` function, whereas PyString_FromFormat has an independent
6643 implementation and uses "%zd" on all platforms for size_t values.
6644 This makes a difference on win64, where ``printf`` needs "%Id" to display
6645 64bit values.

6651 object; previously an int would be returned for small values. the __long__
6652 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006662 was correctly parsed but parsing of subsequent arguments failed.
6663
Vinay Sajip35e3b032008-09-01 14:33:59 +00006664- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006665 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6666 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6667 when given a tuple of classes as second argument, were looking up
6668 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6669 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00006816- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6817 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6818 extensions do not automatically benefit from the class attribute
6819 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6820 to their tp_flags field if they care. This is a backwards
6821 compatibility feature; in 3.0, all types will use the cache by
6822 default.
6823
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006824- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +00006837- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6838 ValueError consistently across platforms.
6839
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006840- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6841 (64bit Unix, for example), unichr() would truncate its argument and return
6842 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006846- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6847 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6848
Antoine Pitrou92f82162008-07-25 22:22:08 +00006849- Issue #1819: function calls with several named parameters are now on
6850 average 35% faster (as measured by pybench).
6851
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006852- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6853 the python debugger steps into a class statement: the free variables (local
6854 variables defined in an outer scope) would be deleted from the outer scope.
6855
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006856- Issue #2620: Overflow checking when allocating or reallocating memory
6857 was not always being done properly in some python types and extension
6858 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6859 all been updated to perform better checks and places in the code that
6860 would previously leak memory on the error path when such an allocation
6861 failed have been fixed.

6867
Benjamin Petersone977ad42008-08-20 01:42:01 +00006868- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6869 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6870
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006871- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6872 version reported by these tools does not necessarily follow the python
6873 version numbering scheme, so the module is less strict when parsing it.
6874
Nick Coghlanf70385a2008-08-18 12:42:46 +00006875- Issue #2235: Added Py3k warnings for types which will become unhashable
6876 under the stricter __hash__ inheritance rules in 3.0. Several types
6877 which did not meet the rules for hash invariants and were already
6878 unhashable in 3.0 have now been explicitly flagged as unhashable in
6879 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6880 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6881
Brett Cannon88f801d2008-08-18 00:46:22 +00006882- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00006913- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6914 since mimetools itself is deprecated. Because modules are cached, all
6915 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6916
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006917- Issue #3134: shutil referenced undefined WindowsError symbol.

6926 a MemoryError rather than silently stop the iteration.
6927
Guido van Rossum59ce9012008-08-09 14:55:34 +00006928- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6929 to _sre.compile() will now be rejected. This should not affect anybody
6930 since the re.compile() function never generates invalid re-bytecode.
6931
Skip Montanaroa032bf42008-08-08 22:52:51 +00006932- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6933 upon first access it can be automatically initialized from the csv file if
6934 it wasn't initialized during instantiation.
6935
Brett Cannon3aa2a492008-08-06 22:28:09 +00006936- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6937 the reload() built-in has been removed.
6938
Brett Cannon7e30b672008-08-04 21:52:25 +00006939- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006940 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006951 asking for a specific length. This problem only affected files opened
6952 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006953

6978 file name rather than a ZipInfo instance, so files are extracted with
6979 mode 0600 rather than 000 under Unix.
6980
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006981- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6982 argument in python 2.5, this broke code that subclassed Popen to include its
6983 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006993- Issue #2235: the C API function PyObject_HashNotImplemented and its
6994 interaction with the tp_hash slot (added in 2.6b2) are now documented
6995
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006996- Issue #643841: The language reference now provides more detailed
6997 coverage of the lookup process for special methods. The disclaimers
6998 regarding lack of coverage of new-style classes have also been
6999 removed, since the coverage is now fairly reasonable.

7003================================
7004
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007005*Release date: 17-Jul-2008*
7006
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007007Core and Builtins
7008-----------------
7009
Georg Brandl3e483f62008-07-16 22:57:41 +00007010- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7011 its methods now allow for items objects that can be converted to
7012 an integer using operator.index().
7013
Mark Dickinson64b7e502008-07-16 09:40:03 +00007014- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7015 produced a ValueError instead of giving the correct float.
7016
Eric Smitha5fa5a22008-07-16 00:11:49 +00007017- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7018 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7019
Mark Dickinson7103aa42008-07-15 19:08:33 +00007020- Issue #3008: the float type has a new instance method 'float.hex'
7021 and a new class method 'float.fromhex' to convert floating-point
7022 numbers to and from hexadecimal strings, respectively.
7023
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007024- Issue #2235: __hash__ is once again inherited by default. To allow
7025 collections.Hashable to remain meaningful in the presence of the
7026 default hash implementation (object.__hash__), it is now possible
7027 to explicit block inheritance of hash by setting __hash__=None at
7028 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7029 level.
7030
Nick Coghlanb028f502008-07-13 14:52:36 +00007031- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7032 the parent module cannot be found while performing an absolute import.
7033 This means that an incorrectly defined __package__ attribute will
7034 now only prevent relative imports in that module rather than causing
7035 all imports from that module to fail.
7036
Nick Coghlan14ff9942008-07-08 14:21:42 +00007037- Issue #2517: Allow unicode messages in Exceptions again by correctly
7038 bypassing the instance dictionary when looking up __unicode__ on
7039 new-style classes.
7040
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007041- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7042 set to a custom object whose write() method happens to install
7043 another file in sys.stdout.
7044
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007045- Issue #3088: Corrected a race condition in classes derived from
7046 threading.local: the first member set by a thread could be saved in
7047 another thread's dictionary.
7048
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007049- Issue #3004: Minor change to slice.indices(): the start and stop
7050 arguments are now treated identically, making the behaviour easier
7051 to describe and understand. For example, slice(None, -10,
7052 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7053 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7054 10, -1).
7055
Georg Brandl278fc502008-07-19 12:46:12 +00007056- Issue #3219: Calling a function with repeated keyword arguments,
7057 f(a=2, a=23), would not cause a syntax error. This was a regression
7058 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007059
Georg Brandl278fc502008-07-19 12:46:12 +00007060- Issue #2862: Make int and float freelist management consistent with
7061 other freelists. Changes their CompactFreeList apis into
7062 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007063

7065-------
7066
Thomas Heller57adf222008-08-14 19:10:48 +00007067- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7068 api functions without holding the GIL, which could lead to a fatal
7069 error when they failed.
7070
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007071- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00007079- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7080 ForkingPickler.register() to resolve conflict with ctypes.
7081
Vinay Sajip51e65192008-07-18 09:01:10 +00007082- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00007083
Thomas Heller880f5292008-07-15 19:39:38 +00007084- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7085 a valid dlerror() message.
7086
Thomas Heller2bad6572008-07-15 17:19:50 +00007087- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7088 incomplete structure was created.
7089
Brett Cannon3d0b9f02008-07-13 01:15:07 +00007090- Issue #3339: dummy_thread.acquire() should not return None.

7093
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007094- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007095
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007096- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7097 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007098 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007099 content-length. The problem had been corrected in the 2.4 branch, but never
7100 merged into trunk.
7101
Georg Brandle78fbcc2008-07-05 10:13:36 +00007102- Issue #2663: add filtering capability to shutil.copytree().

7107
7108- Issue #1746: Correct handling of zipfile archive comments (previously
7109 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00007110 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00007111
Vinay Sajip51e65192008-07-18 09:01:10 +00007112- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007113 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00007114
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007115- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007506 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007507
7508 This is controlled by the configure argument ``--with-universal-archs``:
7509
7510 - ``--with-universal-archs=all``: install 4-way universal
7511
7512 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7513
7514 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7515
7516 This option should be used in combination with ``--enable-universalsdk=``.
7517
7518 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 +00007567- Issue #1631171: Re-implement the 'warnings' module in C (the
7568 original Python code has been kept as backup). This will allow for
7569 using the 'warning's machinery in such places as the parser where
7570 use of pure Python code is not possible. Both the ``showarning()``
7571 and ``formatwarning()`` gain an optional 'line' argument which is
7572 not called by default for backwards-compatibility reasons. Setting
7573 ``warnings.showwarning()`` to an implementation that lacks support
7574 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007637- Issue #2550: The approach used by client/server code for obtaining
7638 ports to listen on in network-oriented tests has been refined in an
7639 effort to facilitate running multiple instances of the entire
7640 regression test suite in parallel without issue.
7641 test_support.bind_port() has been fixed such that it will always
7642 return a unique port -- which wasn't always the case with the
7643 previous implementation, especially if socket options had been set
7644 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7645 new implementation of bind_port() will actually raise an exception
7646 if it is passed an AF_INET/SOCK_STREAM socket with either the
7647 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7648 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7649 the socket it's been passed. This currently only applies to
7650 Windows. This option prevents any other sockets from binding to the
7651 host/port we've bound to, thus removing the possibility of the
7652 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7653 when a second SOCK_STREAM socket binds and accepts to a host/port
7654 that's already been bound by another socket. The optional preferred
7655 port parameter to bind_port() has been removed. Under no
7656 circumstances should tests be hard coding ports!
7657
7658 test_support.find_unused_port() has also been introduced, which will
7659 pass a temporary socket object to bind_port() in order to obtain an
7660 unused port. The temporary socket object is then closed and
7661 deleted, and the port is returned. This method should only be used
7662 for obtaining an unused port in order to pass to an external program
7663 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7664 a parameter to a server-oriented class that doesn't give you direct
7665 access to the underlying socket used.
7666
7667 Finally, test_support.HOST has been introduced, which should be used
7668 for the host argument of any relevant socket calls (i.e. bind and
7669 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007670
7671 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007672 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007673 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7674 test_asynchat and test_socket_ssl.
7675
Georg Brandl3ee81df2008-05-17 18:14:43 +00007676 It is now possible for multiple instances of the regression test
7677 suite to run in parallel without issue.

7944-----------------
7945
Fred Drakea8ee94b2008-03-01 02:45:07 +00007946- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007947 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007948
Georg Brandlad61bc82008-02-23 15:11:18 +00007949- Issue #2067: file.__exit__() now calls subclasses' close() method.
7950
7951- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007952
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007953- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007954 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007955
Eric Smitha73fbe72008-02-23 03:09:44 +00007956- Added the future_builtins module, which contains hex() and oct().
7957 These are the PEP 3127 version of these functions, designed to be
7958 compatible with the hex() and oct() builtins from Python 3.0. They
7959 differ slightly in their output formats from the existing, unchanged
7960 Python 2.6 builtins. The expected usage of the future_builtins
7961 module is:
7962 from future_builtins import hex, oct
7963
Eric Smith7ef40bf2008-02-20 23:34:22 +00007964- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7965 exponents for exponents with absolute value < 100. Follows C99
7966 standard. This is a change on Windows, which would use 3 digits.
7967 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7968 so that any alterations it does to the resulting string will be
7969 available in stringlib/formatter.h (for float.__format__).
7970
Eric Smith5a3c1352008-02-19 13:21:56 +00007971- Implemented PEP 3101, Advanced String Formatting. This adds a new
7972 builtin format(); a format() method for str and unicode; a
7973 __format__() method to object, str, unicode, int, long, float, and
7974 datetime; the class string.Formatter; and the C API
7975 PyObject_Format().
7976
Georg Brandl3ee81df2008-05-17 18:14:43 +00007977- Fixed several potential crashes, all caused by specially crafted
7978 __del__ methods exploiting objects in temporarily inconsistent
7979 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007980
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007981- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007982 prevent a possible crash: an Abstract Base Class would try to access
7983 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007984
Georg Brandl3ee81df2008-05-17 18:14:43 +00007985- Fixed repr() and str() of complex numbers with infinity or nan as
7986 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007987
Georg Brandl3ee81df2008-05-17 18:14:43 +00007988- Clear all free lists during a gc.collect() of the highest generation
7989 in order to allow pymalloc to free more arenas. Python may give back
7990 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007991
Georg Brandl3ee81df2008-05-17 18:14:43 +00007992- Issue #2045: Fix an infinite recursion triggered when printing a
7993 subclass of collections.defaultdict, if its default_factory is set
7994 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007995
Christian Heimesf75dbef2008-02-08 00:11:31 +00007996- Fixed a minor memory leak in dictobject.c. The content of the free
7997 list was not freed on interpreter shutdown.
7998
Georg Brandl21e99f42010-03-07 15:23:59 +00007999- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008000 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008001
Georg Brandl3ee81df2008-05-17 18:14:43 +00008002- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8003 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008004 to compact the internal free lists of pre-allocted ints and floats.
8005
Georg Brandl3ee81df2008-05-17 18:14:43 +00008006- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8007 calls. Python expected the return type int but the fork familie
8008 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008009
Georg Brandl3ee81df2008-05-17 18:14:43 +00008010- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8011 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008012
Georg Brandl3ee81df2008-05-17 18:14:43 +00008013- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8014 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008015
Georg Brandl3ee81df2008-05-17 18:14:43 +00008016- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8017 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008018
Georg Brandl3ee81df2008-05-17 18:14:43 +00008019- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8020 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008021
Georg Brandl3ee81df2008-05-17 18:14:43 +00008022- Patch #1473257: generator objects gain a gi_code attribute. This is
8023 the same object as the func_code attribute of the function that
8024 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008025
Georg Brandl3ee81df2008-05-17 18:14:43 +00008026- Issue #1920: "while 0" statements were completely removed by the
8027 compiler, even in the presence of an "else" clause, which is
8028 supposed to be run when the condition is false. Now the compiler
8029 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008030
Guido van Rossumeead05f2008-01-24 18:21:02 +00008031- A few crashers fixed: weakref_in_del.py (issue #1377858);
8032 loosing_dict_ref.py (issue #1303614, test67.py);
8033 borrowed_ref_[34].py (not in tracker).
8034
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008035- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008036 suppressed while an extension is loaded by calling SetErrorMode in
8037 dynload_win.c. The error is still reported properly.
8038
Georg Brandl3ee81df2008-05-17 18:14:43 +00008039- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008040 several extension methods and modules do not work without unicode
8041 support.
8042
Georg Brandl26543b12008-01-21 18:36:51 +00008043- Issue #1882: when compiling code from a string, encoding cookies in the
8044 second line of code were not always recognized correctly.
8045
Georg Brandl14404b62008-01-19 19:27:05 +00008046- Issue #1679: "0x" was taken as a valid integer literal.
8047
Georg Brandl6caad7d2008-01-26 14:19:22 +00008048- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008049 added.
8050
Christian Heimesc94e2b52008-01-14 04:13:37 +00008051- sys.float_info / PyFloat_GetInfo: The floating point information
8052 object was converted from a dict to a specialized structseq object.
8053
Georg Brandl3ee81df2008-05-17 18:14:43 +00008054- Patch #1816: Added sys.flags structseq. It exposes the status of
8055 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008056
Georg Brandl3ee81df2008-05-17 18:14:43 +00008057- Objects/structseq.c: Implemented new structseq representation. The
8058 patch makes structseqs (e.g. the return value of os.stat) more
8059 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008060
Georg Brandl3ee81df2008-05-17 18:14:43 +00008061- Patch #1700288: added a type attribute cache that caches method
8062 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008063
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008064- Bug #1776: __import__() no longer accepts filenames on any platform.
8065 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008066
Georg Brandlaed6c662008-01-07 17:25:53 +00008067- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8068
Georg Brandl3ee81df2008-05-17 18:14:43 +00008069- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8070 envvar and sys.dont_write_bytecode attribute. All these can be set
8071 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008072
Georg Brandl3ee81df2008-05-17 18:14:43 +00008073- Improve some exception messages when Windows fails to load an
8074 extension module. Now we get for example '%1 is not a valid Win32
8075 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008076
Georg Brandl3ee81df2008-05-17 18:14:43 +00008077- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008079- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8080 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008081
Christian Heimes0a8143f2007-12-18 23:22:54 +00008082- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008083 and INF. float("nan"), float("inf") and float("-inf") now work on
8084 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008085
Georg Brandl3ee81df2008-05-17 18:14:43 +00008086- Compiler now generates simpler and faster code for dictionary
8087 literals. The oparg for BUILD_MAP now indicates an estimated
8088 dictionary size. There is a new opcode, STORE_MAP, for adding
8089 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008090
Georg Brandl3ee81df2008-05-17 18:14:43 +00008091- Issue #1638: %zd configure test fails on Linux.

8104 __package__ attribute.
8105
Georg Brandl3ee81df2008-05-17 18:14:43 +00008106- Issue #1402: Fix a crash on exit, when another thread is still
8107 running, and if the deallocation of its frames somehow calls the
8108 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008109

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008113 attribute of an empty cell object.
8114
Georg Brandl3ee81df2008-05-17 18:14:43 +00008115- Issue #1460: The utf-7 incremental decoder did not accept truncated
8116 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00008117
Georg Brandl3ee81df2008-05-17 18:14:43 +00008118- Patch #1739468: Directories and zipfiles containing a __main__.py
8119 file can now be directly executed by passing their name to the
8120 interpreter. The directory/zipfile is automatically inserted as the
8121 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008122
Georg Brandl3ee81df2008-05-17 18:14:43 +00008123- Issue #1265: Fix a problem with sys.settrace, if the tracing
8124 function uses a generator expression when at the same time the
8125 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008126
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008127- sets and frozensets now have an isdisjoint() method.
8128
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008129- optimize the performance of builtin.sum().
8130
Neal Norwitz44f326e2007-10-05 05:29:17 +00008131- Fix warnings found by the new version of the Coverity checker.
8132
Georg Brandl21e99f42010-03-07 15:23:59 +00008133- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008134 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8135 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008136
Georg Brandl3ee81df2008-05-17 18:14:43 +00008137- Issue #1686386: Tuple's tp_repr did not take into account the
8138 possibility of having a self-referential tuple, which is possible
8139 from C code. Nor did object's tp_str consider that a type's tp_str
8140 could do something that could lead to an inifinite recursion.
8141 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8142 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008143
Georg Brandl3ee81df2008-05-17 18:14:43 +00008144- Issue #1164: It was possible to trigger deadlock when using the
8145 'print' statement to write to a file since the GIL was not released
8146 as needed. Now PyObject_Print() does the right thing along with
8147 various tp_print implementations of the built-in types and those in
8148 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008149
Georg Brandl3ee81df2008-05-17 18:14:43 +00008150- Issue #1147: Exceptions were directly allowing string exceptions in
8151 their throw() method even though string exceptions no longer
8152 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008153
Georg Brandl3ee81df2008-05-17 18:14:43 +00008154- Issue #1096: Prevent a segfault from getting the repr of a very
8155 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008156
Brett Cannon1e534b52007-09-07 04:18:30 +00008157- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008158 PyObject_Call() never calling back out to Python code to trigger
8159 recursion depth updates/checks. Required the creation of a static
8160 RuntimeError instance in case normalizing an exception put the
8161 recursion check value past its limit. Fixes crashers
8162 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008163
Georg Brandl3ee81df2008-05-17 18:14:43 +00008164- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008177- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008178 __*__ attributes. (Some already existed, e.g., __doc__ and
8179 __name__.)

Georg Brandl3ee81df2008-05-17 18:14:43 +00008188 "except E as target:". This is to provide forwards compatibility
8189 with Python 3.0.

8209
Guido van Rossum143b5642007-03-23 04:58:42 +00008210- Bug #1683368: The object.__init__() and object.__new__() methods are
8211 now stricter in rejecting excess arguments. The only time when
8212 either allows excess arguments is when it is not overridden and the
8213 other one is. For backwards compatibility, when both are
8214 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008215 warning later). Also, type.__init__() insists on the same signature
8216 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008218- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8219 object to complex using its __complex__() method before falling back
8220 to the __float__() method. Therefore, the functions in the cmath
8221 module now can operate on objects that define a __complex__()
8222 method.

8239
Georg Brandl7b9c5552007-03-12 14:30:05 +00008240- Bug #1678647: write a newline after printing an exception in any
8241 case, even when converting the value to a string failed.
8242
Georg Brandl871f1bc2007-03-12 13:17:36 +00008243- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008244 its argument, if it exists. If not, it will work like before. This
8245 allows customizing the output of dir() in the presence of a
8246 __getattr__().

8256 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00008258- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008259 makes the filenames the warning module prints much more sensible
8260 when a PYTHONSTARTUP file is used.

8274 sq_ass_slice instead of the sq_slice slot.
8275
Georg Brandl3ee81df2008-05-17 18:14:43 +00008276- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00008901- unittest now verifies more of its assumptions. In particular,
8902 TestCase and TestSuite subclasses (not instances) are no longer
8903 accepted in TestSuite.addTest(). This should cause no
8904 incompatibility since it never made sense with ordinary subclasses
8905 -- the failure just occurred later, with a more cumbersome
8906 exception.

9179 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009180
Georg Brandl3ee81df2008-05-17 18:14:43 +00009181- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9182 with RFC 3207 and forgets any knowledge obtained from the server not
9183 obtained from the TLS negotiation itself. Patch contributed by Bill
9184 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009185
Georg Brandl3ee81df2008-05-17 18:14:43 +00009186- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009187 that the SMTP.starttls() caller no longer needs to call ehlo()
9188 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009189 does not claim to support starttls. Adds the
9190 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9271 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9272 silently miscode subclasses of those types. Now, it raises a
9273 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009274

Georg Brandl3ee81df2008-05-17 18:14:43 +00009289 time so that opening a database previously created with the DB_DUP
9290 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9291 opens. Specifically: dictionary assignment to a DB object will
9292 replace all values for a given key when the database allows
9293 duplicate values. DB users should use DB.put(k, v) when they want
9294 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009295

9301 characters with ASCII value less than 32. Also, it correctly quotes
9302 dots only if they occur on a single line, as opposed to the previous
9303 behavior of quoting dots if they are the second character of any
9304 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009305

Georg Brandl3ee81df2008-05-17 18:14:43 +00009639- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9640 to ``PyTuple_SetItem``, it can be used to populate a brand new
9641 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00009643- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009645- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9646 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9647 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009648
9649- Patch #1720595: add T_BOOL to the range of structmember types.
9650
9651- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9652 ``PyFloat_GetInfo()`` to the float API.
9653
Georg Brandl3ee81df2008-05-17 18:14:43 +00009654- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9655 of w# format code incorrectly truncated the length to an int, even
9656 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9657 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009658
Georg Brandl3ee81df2008-05-17 18:14:43 +00009659- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9660 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009662- PEP 3123: Provide forward compatibility with Python 3.0, while
9663 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9664 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009666- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9667 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009668
9669- Patch #1733960: Allow T_LONGLONG to accept ints.
9670
9671- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9672
Christian Heimes000a0742008-01-03 22:16:32 +00009673- Added a new API function ``PyImport_ImportModuleNoBlock``.

Georg Brandl6caad7d2008-01-26 14:19:22 +00009675- Bug #1637022: Prefix AST symbols with _Py_.
9676
9677- Fix some leftovers from the conversion from int to Py_ssize_t
9678 (relevant to strings and sequences of more than 2**31 items).
9679
9680- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9681 outside of pystate.c and should not be necessary.
9682
Georg Brandl3ee81df2008-05-17 18:14:43 +00009683- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9684 absolute imports. In earlier versions they might have used relative
9685 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009686
Georg Brandl3ee81df2008-05-17 18:14:43 +00009687- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9688 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009689
Georg Brandl3ee81df2008-05-17 18:14:43 +00009690- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009696- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9697 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9698 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9699 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009713- Removed the macfs module. It had been deprecated since Python 2.5.
9714 This lead to the deprecation of macostools.touched() as it relied
9715 solely on macfs and was a no-op under OS X.
