Mark Hammond323b5da2011-10-17 11:05:36 +110018- Issue #7833: Extension modules built using distutils on Windows will no
19 longer include a "manifest" to prevent them failing at import time in some
20 embedded situations.
21
Benjamin Petersona7b09762011-10-15 13:43:21 -040022- Issue #13186: Fix __delitem__ on old-style instances when invoked through
23 PySequence_DelItem.

26 which was only relevant for the native pthread TLS implementation.
27
Victor Stinner63c22fa2011-09-23 19:37:03 +020028- Issue #7732: Fix a crash on importing a module if a directory has the same
29 name than a Python module (e.g. "__init__.py"): don't close the file twice.
30
Mark Dickinsondbbed042011-09-19 16:38:08 +010031- Issue #12973: Fix overflow checks that invoked undefined behaviour in
32 int.__pow__. These overflow checks were causing int.__pow__ to produce
33 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010034 compiler optimizing the check away. Also fix similar overflow checks
35 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
36 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010037

Antoine Pitrou16166452011-07-12 22:04:20 +020047- Issue #12149: Update the method cache after a type's dictionnary gets
48 cleared by the garbage collector. This fixes a segfault when an instance
49 and its type get caught in a reference cycle, and the instance's
50 deallocator calls one of the methods on the type (e.g. when subclassing
51 IOBase). Diagnosis and patch by Davide Rizzo.
52
Victor Stinnerba8b3a22011-07-08 02:07:45 +020053- Issue #12501: Adjust callable() warning: callable() is only not supported in

Victor Stinner08563d92011-05-30 23:44:13 +020060 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
61 raw_input() interrupted by CTRL+c.
62
Łukasz Langa7a153902011-10-18 17:16:00 +020063- Issue #10860: httplib now correctly handles an empty port after port
64 delimiter in URLs.
65
Barry Warsawc5643282011-07-19 17:06:30 -040066- dict_proxy objects now display their contents rather than just the class
67 name.

79 arguments with the system default encoding just like the write() method
Éric Araujob21f51a2011-10-23 04:37:51 +020080 does, instead of converting it to a raw buffer. This also fixes handling of
81 unicode input in the shlex module (#6988, #1170).

Lars Gustäbel8babfdf2011-09-05 17:04:18 +0200123- Issue #12841: tarfile unnecessarily checked the existence of numerical user

218
Ned Deily87e82bb2011-06-28 19:52:59 -0700219- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
220 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
221 interpreter process. This could cause failures in non-Distutils subprocesses
222 and was unreliable since tests or user programs could modify the interpreter
223 environment after Distutils set it. Instead, have Distutils set the the
224 deployment target only in the environment of each build subprocess. It is
225 still possible to globally override the default by setting
226 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
227 greater or equal to the default value, the value with which the interpreter
228 was built.

237 times without error, and _ProxyFile now closes the wrapped file.
238
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200239- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
240 connection if its getresponse() method fails with a socket error. Patch
241 written by Ezio Melotti.
242
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500243- Issue #9284: Allow inspect.findsource() to find the source of doctest

255
Barry Warsawc5643282011-07-19 17:06:30 -0400256- sys.setcheckinterval() now updates the current ticker count as well as
257 updating the check interval, so if the user decreases the check interval,
258 the ticker doesn't have to wind down to zero from the old starting point
259 before the new interval takes effect. And if the user increases the
260 interval, it makes sure the new limit takes effect right away rather have an
261 early task switch before recognizing the new interval.

1154 This prevents user-created self-referencing ordered dictionaries from
1155 becoming permanently uncollectable GC garbage. The downside is that
1156 removing __del__ means that the internal doubly-linked list has to wait for

1616
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001617- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1618 start byte and the continuation byte(s) are now considered invalid, instead
1619 of the number of bytes specified by the start byte.
1620 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1621 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1622 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1623 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001631- Issue #8748: Fix two issues with comparisons between complex and integer
1632 objects. (1) The comparison could incorrectly return True in some cases
1633 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1634 (2) The comparison raised an OverflowError for large integers, leading
1635 to unpredictable exceptions when combining integers and complex objects
1636 in sets or dicts.
1637
Mark Dickinson81336372010-05-30 12:12:25 +00001638- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00001775- Issue #1533: Fix inconsistency in range function argument processing: any
1776 non-float non-integer argument is now converted to an integer (if possible)
1777 using its __int__ method. Previously, only small arguments were treated this
1778 way; larger arguments (those whose __int__ was outside the range of a C long)
1779 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00001787 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00001788 benefit compared to the dynamic memory allocation fallback. Patch by

1815 inheritance with the underlying socket object. The cheap inheritance has been
1816 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00001829- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1830 operation raises multiple signals and more than one of those signals is
1831 trapped, the specification determines the order in which the signals should be
1832 handled. In many cases this order wasn't being followed, leading to the wrong
1833 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00001834

2001-----------------
2002
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002003- Issue #7301: Add environment variable $PYTHONWARNINGS.
2004
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002005- Issue #8329: Don't return the same lists from select.select when no fds are
2006 changed.
2007
Georg Brandlfee0f442010-05-22 21:26:21 +00002008- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002009 on 64-bit machines. The shift count for either left or right shift is
2010 permitted to be up to sys.maxsize.
2011
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002012- Ensure that tokenization of identifiers is not affected by locale.
2013
Georg Brandlfee0f442010-05-22 21:26:21 +00002014- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002015
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002016- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2017
Georg Brandlfee0f442010-05-22 21:26:21 +00002018- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2019 with a non-empty format string. This is an effort to future-proof user
2020 code. If a derived class does not currently implement __format__ but later
2021 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002022 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002023 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002024
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002025- Issue #8268: Old-style classes (not just instances) now support weak
2026 references.
2027
Georg Brandlfee0f442010-05-22 21:26:21 +00002028- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2029 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00002030
Victor Stinnerc7790ed2010-03-22 12:36:28 +00002031- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00002033- Issue #6474: Make error message from passing an inadequate number of keyword
2034 arguments to a function correct.
2035
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002036- Issue #8164: Don't allow lambda functions to have a docstring.
2037
Victor Stinner66644262010-03-10 22:30:19 +00002038- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002039 (SIGINT). If an error occurs while importing the site module, the error is
2040 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002041 module.
2042
Collin Winter001a3952010-03-18 21:54:01 +00002043- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00002048- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
2049
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002050- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002051 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2052 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002054- Issue #8310: Allow dis to examine new style classes.
2055
Georg Brandlfee0f442010-05-22 21:26:21 +00002056- Issue #8257: The Decimal construct now accepts a float instance directly,
2057 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002058
2059 >>> Decimal(1.1)
2060 Decimal('1.100000000000000088817841970012523233890533447265625')
2061
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002062- collections.Counter() now supports a subtract() method.
2063
Georg Brandlfee0f442010-05-22 21:26:21 +00002064- The functools module now has a total_ordering() class decorator to simplify
2065 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002066
Georg Brandlfee0f442010-05-22 21:26:21 +00002067- The functools module also adds cmp_to_key() as a tool to transition old-style
2068 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002069
Georg Brandlfee0f442010-05-22 21:26:21 +00002070- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2071 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002072
Georg Brandlfee0f442010-05-22 21:26:21 +00002073- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2074 InvalidOperation instead of returning False. (Comparisons involving a quiet
2075 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2076 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002077
Georg Brandlfee0f442010-05-22 21:26:21 +00002078- Issue #2531: Comparison operations between floats and Decimal instances now
2079 return a result based on the numeric values of the operands; previously they
2080 returned an arbitrary result based on the relative ordering of id(float) and
2081 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002082
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002083- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002084 argument `-` which tells it to read files to compile from stdin. Each line is
2085 read on demand and the named file is compiled immediately. (Original patch by
2086 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002087
Georg Brandlfee0f442010-05-22 21:26:21 +00002088- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2089 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002091- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2092 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002093 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002094
Georg Brandlfee0f442010-05-22 21:26:21 +00002095- Comparisons using one of <, <=, >, >= between a complex instance and a
2096 Fractions instance now raise TypeError instead of returning True/False. This
2097 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2098 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002099

2108
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002109- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002110 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2111 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002112
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002113- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2114 deprecated.
2115
Georg Brandlfee0f442010-05-22 21:26:21 +00002116- Issue #7860: platform.uname now reports the correct 'machine' type when Python
2117 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00002118

2123 existing at the same time, causing a Unicode error when configuration code
2124 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00002125

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002153- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002154 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2155 log file to compute the next rollover time. If the log file does not exist,
2156 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002157

Georg Brandlba83f822010-03-14 09:50:54 +00002166- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2167 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2168 This is a behavior change, so email's minor version number is now bumped, to
2169 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002197- Issue #8300: When passing a non-integer argument to struct.pack with any
2198 integer format code, struct.pack first attempts to convert the non-integer
2199 using its __index__ method. If that method is non-existent or raises
2200 TypeError it goes on to try the __int__ method, as described below.
2201
Georg Brandlba83f822010-03-14 09:50:54 +00002202- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2203 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2204 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002205 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2206 inconsistent: __int__ was used for some integer codes but not for others, and
2207 the set of integer codes for which it was used differed between native packing
2208 and standard packing.)

2612Core and Builtins
2613-----------------
2614
Georg Brandlba83f822010-03-14 09:50:54 +00002615- The ``__complex__()`` method is now looked up on the class of instances to
2616 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002618- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

2620
Mark Dickinson1b34d252010-01-01 17:27:30 +00002621- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002622 DeprecationWarning when passed a float argument where an integer was expected.
2623 These functions and methods now raise TypeError instead. The majority of the
2624 effects of this change are in the extension modules, but some core functions
2625 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2626 and many unicode/str methods.

2637 used to drop the time part of the result.
2638

2640 of integers: the result of a/b is now correctly rounded for ints a and b (at
2641 least on IEEE 754 platforms), and in particular does not depend on the
2642 internal representation of a long.

2650
Georg Brandlba83f822010-03-14 09:50:54 +00002651 These executables now work properly with the arch(1) command: ``arch -ppc
2652 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00002809- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2810 decimal string that's guaranteed to round back to x under correct rounding
2811 (with round-half-to-even rounding mode). Previously it gave a string based on
2812 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2813 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2814 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002815
Georg Brandlba83f822010-03-14 09:50:54 +00002816- Issue #7117: On almost all platforms: float-to-string and string-to-float
2817 conversions within Python are now correctly rounded. Places these conversions
2818 occur include: str for floats and complex numbers; the float and complex
2819 constructors; old-style and new-style numeric formatting; serialization and
2820 deserialization of floats and complex numbers using marshal, pickle and json;
2821 parsing of float and imaginary literals in Python code; Decimal-to-float
2822 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002823
Georg Brandlba83f822010-03-14 09:50:54 +00002824 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2825 providing correctly-rounded strtod and dtoa C functions. This code is
2826 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2827 the C compiler. There may be a small number of platforms on which correct
2828 operation of this code cannot be guaranteed, so the code is not used: notably,
2829 this applies to platforms where the C double format is not IEEE 754 binary64,
2830 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2831 and Python's configure script is unable to determine how to change the FPU
2832 precision. On these platforms conversions use the platform strtod and dtoa,
2833 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002835- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2836 uses the correctly-rounded string <-> float conversions described above (when
2837 available), and so produces correctly rounded results that will display nicely
2838 under the float repr. There are two related small changes: (1) round now
2839 accepts any class with an ``__index__()`` method for its second argument (but
2840 no longer accepts floats for the second argument), and (2) an excessively
2841 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2842 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002984
Georg Brandlba83f822010-03-14 09:50:54 +00002985 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2986 (2) parsing of strings representing infinities and nans was locale aware; and
2987 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00002988
Georg Brandlba83f822010-03-14 09:50:54 +00002989- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2990 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2991 but with at least one decimal point and with a default precision
2992 of 12. Previously, the behavior the same but with a default precision of 6.
2993 This more closely matches ``str()``, and reduces surprises when adding
2994 alignment flags to the empty presentation type. This also affects the new
2995 complex.__format__ in the same way.
2996
2997- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2998 classtype's, even if it was None. property now inserts the __doc__ into the
2999 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00003060 untrackable objects are not tracked by the garbage collector. This can reduce
3061 the size of collections and therefore the garbage collection overhead on

3069 internal representation of integers, for performance reasons. Base 2**30 is
3070 enabled by default on 64-bit machines. Add --enable-big-digits option to
3071 configure, which overrides the default. Add sys.long_info structseq to
3072 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00003173- Issue #4597: Fixed exception handling when the __exit__ function of a context
3174 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00003175
Georg Brandlba83f822010-03-14 09:50:54 +00003176- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00003177
Georg Brandlba83f822010-03-14 09:50:54 +00003178- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3179 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3180 instances. On a typical machine this saves 3 bytes of memory (on average) per
3181 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003182
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003183- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3184 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3185 instead of throwing a MemoryError.
3186
Georg Brandlba83f822010-03-14 09:50:54 +00003187- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3188 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003189
Benjamin Petersonc078f922008-11-21 22:27:24 +00003190- Issue #4367: Python would segfault during compiling when the unicodedata
3191 module couldn't be imported and \N escapes were present.
3192
Georg Brandlba83f822010-03-14 09:50:54 +00003193- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3194 file objects with closefd=False. The file descriptor is still kept open but
3195 the file object behaves like a closed file. The ``FileIO`` object also got a
3196 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003197
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003198- Issue #4348: Some bytearray methods returned that didn't cause any change to
3199 the bytearray, returned the same bytearray instead of a copy.
3200
Georg Brandlba83f822010-03-14 09:50:54 +00003201- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00003202
Benjamin Peterson273c2332008-11-17 22:39:09 +00003203- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3204
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003205- Issue #4048: The parser module now correctly validates relative imports.
3206
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003207- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3208 exec statement.
3209
Georg Brandlba83f822010-03-14 09:50:54 +00003210- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3211 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003212
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003213- Issue #4209: Enabling unicode_literals and the print_function in the same
3214 __future__ import didn't work.
3215
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003216- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003217 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003218
Georg Brandlba83f822010-03-14 09:50:54 +00003219- On windows, ``os.chdir()`` given unicode was not working if
3220 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3221 this code path is really executed because I cannot move to such directory on
3222 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003223
Georg Brandlba83f822010-03-14 09:50:54 +00003224- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3225 element is temporarily replaced with an equivalent frozenset. But the
3226 eventual KeyError would always report the empty ``frozenset()`` as the missing
3227 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003228
Georg Brandlba83f822010-03-14 09:50:54 +00003229- Issue #4509: Various issues surrounding resize of bytearray objects to which
3230 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00003231
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00003232- Issue #4748: Lambda generators no longer return a value.
3233
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00003234- Issue #3582: Use native TLS functions on Windows
3235
Gregory P. Smithae91d092009-03-02 05:13:57 +00003236- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
3237
Georg Brandlba83f822010-03-14 09:50:54 +00003238- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
3239 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00003240
Matthias Klose91a3b9e2009-04-05 21:19:13 +00003241- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3242 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003243
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003244- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3245 returned them on 64bit platforms.
3246
Walter Dörwalded960ac2009-05-03 22:36:33 +00003247- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3248 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3249 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3250 of using the replace error handler in PyUnicode_DecodeUTF8().
3251
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003252- Issue #3739: The unicode-internal encoder now reports the number of characters
3253 consumed like any other encoder (instead of the number of bytes).
3254
Georg Brandlba83f822010-03-14 09:50:54 +00003255- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3256 allocator will be automatically disabled when running under Valgrind. This
3257 gives improved memory leak detection when running under Valgrind, while taking
3258 advantage of pymalloc at other times.

3281 Patch by Jean-Paul Calderone.
Antoine Pitrou30b3b352009-12-02 20:37:54 +00003282
Tarek Ziadéa5076a22009-11-29 22:20:30 +00003283- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
3284 ownership when the group is not forced, because the group may be different
3285 from the user's group and inherit from its container when the test is run.
3286

Georg Brandlba83f822010-03-14 09:50:54 +00003327- Issue #6816: runpy now provides a run_path function that allows Python code to
3328 execute file paths that refer to source or compiled Python files as well as
3329 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00003330 __main__.py file. This allows applications that run other Python scripts to
3331 support the same flexibility as the CPython command line itself.
3332
Georg Brandlba83f822010-03-14 09:50:54 +00003333- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
3334 connection with another process, rather than looping endlessly. The default
3335 timeout is 20 seconds, which should be amply sufficient for local connections.

Antoine Pitrouaec41242009-11-02 11:34:27 +00003352 a modification is done through it. This fixes inconsistencies and test

4425 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4426 neither __int__ nor __long__, TypeError used to be raised (with a

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00004604 AttributeError instead of RuntimeError, depending in which C API call

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004623- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4624
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004625- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4626 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4627 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4628 ``printf`` function, whereas PyString_FromFormat has an independent
4629 implementation and uses "%zd" on all platforms for size_t values.
4630 This makes a difference on win64, where ``printf`` needs "%Id" to display
4631 64bit values.
4632
Benjamin Peterson97179b02008-09-09 20:55:01 +00004633- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4634 error.

4637 object; previously an int would be returned for small values. the __long__
4638 method is allowed to return either an int or a long, but the behaviour of
4639 float objects should not change to respect backward compatibility.
4640
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004641- Issue #3751: str.rpartition would perform a left-partition when called with
4642 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004647 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004648 was correctly parsed but parsing of subsequent arguments failed.
4649
Vinay Sajip35e3b032008-09-01 14:33:59 +00004650- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004651 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4652 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4653 when given a tuple of classes as second argument, were looking up
4654 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4655 type object.
4656
Neal Norwitz18aa3882008-08-24 05:04:52 +00004657- Fix crashes on memory allocation failure found with failmalloc.
4658
4659- Fix memory leaks found with valgrind and update suppressions file.
4660
4661- Fix compiler warnings in opt mode which would lead to invalid memory reads.

4701
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004702- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004726 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4727 for catch_warnings() also led to an improvement in the raising of a

4800-----------------
4801
Guido van Rossumf8402962008-08-20 15:01:50 +00004802- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4803 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4804 extensions do not automatically benefit from the class attribute
4805 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4806 to their tp_flags field if they care. This is a backwards
4807 compatibility feature; in 3.0, all types will use the cache by
4808 default.
4809
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004810- Keyword arguments can now follow starred arguments. (``f(a, *args,
4811 keyword=23)`` is now valid syntax.)
4812
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004813- ctypes function pointers that are COM methods have a boolean True
4814 value again.

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004816- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4817 by denying s# to parse objects that have a releasebuffer procedure,
4818 and introducing s*.

Mark Dickinsonb6467572008-08-04 21:30:09 +00004823- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4824 ValueError consistently across platforms.
4825
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004826- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4827 (64bit Unix, for example), unichr() would truncate its argument and return
4828 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4829
Neal Norwitze7d8be82008-07-31 17:17:14 +00004830- Apply security patches from Apple.
4831
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004832- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00004835- Issue #1819: function calls with several named parameters are now on
4836 average 35% faster (as measured by pybench).
4837
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004838- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4839 the python debugger steps into a class statement: the free variables (local
4840 variables defined in an outer scope) would be deleted from the outer scope.
4841
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004842- Issue #2620: Overflow checking when allocating or reallocating memory
4843 was not always being done properly in some python types and extension
4844 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4845 all been updated to perform better checks and places in the code that
4846 would previously leak memory on the error path when such an allocation
4847 failed have been fixed.

4853
Benjamin Petersone977ad42008-08-20 01:42:01 +00004854- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4855 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4856
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004857- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4858 version reported by these tools does not necessarily follow the python
4859 version numbering scheme, so the module is less strict when parsing it.
4860
Nick Coghlanf70385a2008-08-18 12:42:46 +00004861- Issue #2235: Added Py3k warnings for types which will become unhashable
4862 under the stricter __hash__ inheritance rules in 3.0. Several types
4863 which did not meet the rules for hash invariants and were already
4864 unhashable in 3.0 have now been explicitly flagged as unhashable in
4865 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4866 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4867
Brett Cannon88f801d2008-08-18 00:46:22 +00004868- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4869 imported into the module but exposed as part of the module's API.
4870

4897 thread-safe.
4898
Brett Cannonbf3157b2008-08-14 05:00:03 +00004899- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4900 since mimetools itself is deprecated. Because modules are cached, all
4901 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4902
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004903- Issue #3134: shutil referenced undefined WindowsError symbol.

4906 menu entries were not deleted.
4907
Brett Cannon83e81842008-08-09 23:30:55 +00004908- Copied the implementation of reduce() to _functools.reduce() to have a

4912 a MemoryError rather than silently stop the iteration.
4913
Guido van Rossum59ce9012008-08-09 14:55:34 +00004914- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4915 to _sre.compile() will now be rejected. This should not affect anybody
4916 since the re.compile() function never generates invalid re-bytecode.
4917
Skip Montanaroa032bf42008-08-08 22:52:51 +00004918- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4919 upon first access it can be automatically initialized from the csv file if
4920 it wasn't initialized during instantiation.
4921
Brett Cannon3aa2a492008-08-06 22:28:09 +00004922- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4923 the reload() built-in has been removed.
4924
Brett Cannon7e30b672008-08-04 21:52:25 +00004925- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004926 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4934 raised an AttributeError.
4935
Benjamin Peterson01a24322008-07-28 23:35:27 +00004936- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004937 asking for a specific length. This problem only affected files opened
4938 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004939

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004963- Issue #3394: zipfile.writestr sets external attributes when passed a
4964 file name rather than a ZipInfo instance, so files are extracted with
4965 mode 0600 rather than 000 under Unix.
4966
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004967- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4968 argument in python 2.5, this broke code that subclassed Popen to include its
4969 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004979- Issue #2235: the C API function PyObject_HashNotImplemented and its
4980 interaction with the tp_hash slot (added in 2.6b2) are now documented
4981
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004982- Issue #643841: The language reference now provides more detailed
4983 coverage of the lookup process for special methods. The disclaimers
4984 regarding lack of coverage of new-style classes have also been
4985 removed, since the coverage is now fairly reasonable.

4989================================
4990
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004991*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004993Core and Builtins
4994-----------------
4995
Georg Brandl3e483f62008-07-16 22:57:41 +00004996- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4997 its methods now allow for items objects that can be converted to
4998 an integer using operator.index().
4999
Mark Dickinson64b7e502008-07-16 09:40:03 +00005000- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5001 produced a ValueError instead of giving the correct float.
5002
Eric Smitha5fa5a22008-07-16 00:11:49 +00005003- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5004 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5005
Mark Dickinson7103aa42008-07-15 19:08:33 +00005006- Issue #3008: the float type has a new instance method 'float.hex'
5007 and a new class method 'float.fromhex' to convert floating-point
5008 numbers to and from hexadecimal strings, respectively.
5009
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005010- Issue #2235: __hash__ is once again inherited by default. To allow
5011 collections.Hashable to remain meaningful in the presence of the
5012 default hash implementation (object.__hash__), it is now possible
5013 to explicit block inheritance of hash by setting __hash__=None at
5014 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5015 level.
5016
Nick Coghlanb028f502008-07-13 14:52:36 +00005017- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5018 the parent module cannot be found while performing an absolute import.
5019 This means that an incorrectly defined __package__ attribute will
5020 now only prevent relative imports in that module rather than causing
5021 all imports from that module to fail.
5022
Nick Coghlan14ff9942008-07-08 14:21:42 +00005023- Issue #2517: Allow unicode messages in Exceptions again by correctly
5024 bypassing the instance dictionary when looking up __unicode__ on
5025 new-style classes.
5026
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005027- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5028 set to a custom object whose write() method happens to install
5029 another file in sys.stdout.
5030
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005031- Issue #3088: Corrected a race condition in classes derived from
5032 threading.local: the first member set by a thread could be saved in
5033 another thread's dictionary.
5034
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005035- Issue #3004: Minor change to slice.indices(): the start and stop
5036 arguments are now treated identically, making the behaviour easier
5037 to describe and understand. For example, slice(None, -10,
5038 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5039 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5040 10, -1).
5041
Georg Brandl278fc502008-07-19 12:46:12 +00005042- Issue #3219: Calling a function with repeated keyword arguments,
5043 f(a=2, a=23), would not cause a syntax error. This was a regression
5044 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005045
Georg Brandl278fc502008-07-19 12:46:12 +00005046- Issue #2862: Make int and float freelist management consistent with
5047 other freelists. Changes their CompactFreeList apis into
5048 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005049

5052
Thomas Heller57adf222008-08-14 19:10:48 +00005053- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5054 api functions without holding the GIL, which could lead to a fatal
5055 error when they failed.
5056
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005057- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005065- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5066 ForkingPickler.register() to resolve conflict with ctypes.
5067
Vinay Sajip51e65192008-07-18 09:01:10 +00005068- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00005070- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5071 a valid dlerror() message.
5072
Thomas Heller2bad6572008-07-15 17:19:50 +00005073- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5074 incomplete structure was created.
5075

5079
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005080- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005081
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005082- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5083 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005084 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005085 content-length. The problem had been corrected in the 2.4 branch, but never
5086 merged into trunk.
5087
Georg Brandle78fbcc2008-07-05 10:13:36 +00005088- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005099 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005100
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005101- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5102 handling is now the same as that of other special attributes like __name__).
5103
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005104- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5105 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00005494 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005495
5496 This is controlled by the configure argument ``--with-universal-archs``:
5497
5498 - ``--with-universal-archs=all``: install 4-way universal
5499
5500 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5501
5502 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5503
5504 This option should be used in combination with ``--enable-universalsdk=``.
5505
5506 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 +00005556- Issue #1631171: Re-implement the 'warnings' module in C (the
5557 original Python code has been kept as backup). This will allow for
5558 using the 'warning's machinery in such places as the parser where
5559 use of pure Python code is not possible. Both the ``showarning()``
5560 and ``formatwarning()`` gain an optional 'line' argument which is
5561 not called by default for backwards-compatibility reasons. Setting
5562 ``warnings.showwarning()`` to an implementation that lacks support
5563 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005626- Issue #2550: The approach used by client/server code for obtaining
5627 ports to listen on in network-oriented tests has been refined in an
5628 effort to facilitate running multiple instances of the entire
5629 regression test suite in parallel without issue.
5630 test_support.bind_port() has been fixed such that it will always
5631 return a unique port -- which wasn't always the case with the
5632 previous implementation, especially if socket options had been set
5633 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5634 new implementation of bind_port() will actually raise an exception
5635 if it is passed an AF_INET/SOCK_STREAM socket with either the
5636 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5637 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5638 the socket it's been passed. This currently only applies to
5639 Windows. This option prevents any other sockets from binding to the
5640 host/port we've bound to, thus removing the possibility of the
5641 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5642 when a second SOCK_STREAM socket binds and accepts to a host/port
5643 that's already been bound by another socket. The optional preferred
5644 port parameter to bind_port() has been removed. Under no
5645 circumstances should tests be hard coding ports!
5646
5647 test_support.find_unused_port() has also been introduced, which will
5648 pass a temporary socket object to bind_port() in order to obtain an
5649 unused port. The temporary socket object is then closed and
5650 deleted, and the port is returned. This method should only be used
5651 for obtaining an unused port in order to pass to an external program
5652 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5653 a parameter to a server-oriented class that doesn't give you direct
5654 access to the underlying socket used.
5655
5656 Finally, test_support.HOST has been introduced, which should be used
5657 for the host argument of any relevant socket calls (i.e. bind and
5658 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005659
5660 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005661 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

5663 test_asynchat and test_socket_ssl.
5664
Georg Brandl3ee81df2008-05-17 18:14:43 +00005665 It is now possible for multiple instances of the regression test
5666 suite to run in parallel without issue.

5932Core and builtins
5933-----------------
5934
Fred Drakea8ee94b2008-03-01 02:45:07 +00005935- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005936 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005937
Georg Brandlad61bc82008-02-23 15:11:18 +00005938- Issue #2067: file.__exit__() now calls subclasses' close() method.
5939
5940- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005941
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005942- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005943 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005944
Eric Smitha73fbe72008-02-23 03:09:44 +00005945- Added the future_builtins module, which contains hex() and oct().
5946 These are the PEP 3127 version of these functions, designed to be
5947 compatible with the hex() and oct() builtins from Python 3.0. They
5948 differ slightly in their output formats from the existing, unchanged
5949 Python 2.6 builtins. The expected usage of the future_builtins
5950 module is:
5951 from future_builtins import hex, oct
5952
Eric Smith7ef40bf2008-02-20 23:34:22 +00005953- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5954 exponents for exponents with absolute value < 100. Follows C99
5955 standard. This is a change on Windows, which would use 3 digits.
5956 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5957 so that any alterations it does to the resulting string will be
5958 available in stringlib/formatter.h (for float.__format__).
5959
Eric Smith5a3c1352008-02-19 13:21:56 +00005960- Implemented PEP 3101, Advanced String Formatting. This adds a new
5961 builtin format(); a format() method for str and unicode; a
5962 __format__() method to object, str, unicode, int, long, float, and
5963 datetime; the class string.Formatter; and the C API
5964 PyObject_Format().
5965
Georg Brandl3ee81df2008-05-17 18:14:43 +00005966- Fixed several potential crashes, all caused by specially crafted
5967 __del__ methods exploiting objects in temporarily inconsistent
5968 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005969
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005970- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005971 prevent a possible crash: an Abstract Base Class would try to access
5972 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005973
Georg Brandl3ee81df2008-05-17 18:14:43 +00005974- Fixed repr() and str() of complex numbers with infinity or nan as
5975 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005976
Georg Brandl3ee81df2008-05-17 18:14:43 +00005977- Clear all free lists during a gc.collect() of the highest generation
5978 in order to allow pymalloc to free more arenas. Python may give back
5979 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005980
Georg Brandl3ee81df2008-05-17 18:14:43 +00005981- Issue #2045: Fix an infinite recursion triggered when printing a
5982 subclass of collections.defaultdict, if its default_factory is set
5983 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005984
Christian Heimesf75dbef2008-02-08 00:11:31 +00005985- Fixed a minor memory leak in dictobject.c. The content of the free
5986 list was not freed on interpreter shutdown.
5987
Georg Brandl21e99f42010-03-07 15:23:59 +00005988- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005989 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005990
Georg Brandl3ee81df2008-05-17 18:14:43 +00005991- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5992 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005993 to compact the internal free lists of pre-allocted ints and floats.
5994
Georg Brandl3ee81df2008-05-17 18:14:43 +00005995- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5996 calls. Python expected the return type int but the fork familie
5997 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005998
Georg Brandl3ee81df2008-05-17 18:14:43 +00005999- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6000 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006001
Georg Brandl3ee81df2008-05-17 18:14:43 +00006002- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6003 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006004
Georg Brandl3ee81df2008-05-17 18:14:43 +00006005- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6006 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006007
Georg Brandl3ee81df2008-05-17 18:14:43 +00006008- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6009 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006010
Georg Brandl3ee81df2008-05-17 18:14:43 +00006011- Patch #1473257: generator objects gain a gi_code attribute. This is
6012 the same object as the func_code attribute of the function that
6013 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006014
Georg Brandl3ee81df2008-05-17 18:14:43 +00006015- Issue #1920: "while 0" statements were completely removed by the
6016 compiler, even in the presence of an "else" clause, which is
6017 supposed to be run when the condition is false. Now the compiler
6018 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006019
Guido van Rossumeead05f2008-01-24 18:21:02 +00006020- A few crashers fixed: weakref_in_del.py (issue #1377858);
6021 loosing_dict_ref.py (issue #1303614, test67.py);
6022 borrowed_ref_[34].py (not in tracker).
6023
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006024- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006025 suppressed while an extension is loaded by calling SetErrorMode in
6026 dynload_win.c. The error is still reported properly.
6027
Georg Brandl3ee81df2008-05-17 18:14:43 +00006028- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006029 several extension methods and modules do not work without unicode
6030 support.
6031
Georg Brandl26543b12008-01-21 18:36:51 +00006032- Issue #1882: when compiling code from a string, encoding cookies in the
6033 second line of code were not always recognized correctly.
6034
Georg Brandl14404b62008-01-19 19:27:05 +00006035- Issue #1679: "0x" was taken as a valid integer literal.
6036
Georg Brandl6caad7d2008-01-26 14:19:22 +00006037- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006038 added.
6039
Christian Heimesc94e2b52008-01-14 04:13:37 +00006040- sys.float_info / PyFloat_GetInfo: The floating point information
6041 object was converted from a dict to a specialized structseq object.
6042
Georg Brandl3ee81df2008-05-17 18:14:43 +00006043- Patch #1816: Added sys.flags structseq. It exposes the status of
6044 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006045
Georg Brandl3ee81df2008-05-17 18:14:43 +00006046- Objects/structseq.c: Implemented new structseq representation. The
6047 patch makes structseqs (e.g. the return value of os.stat) more
6048 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006049
Georg Brandl3ee81df2008-05-17 18:14:43 +00006050- Patch #1700288: added a type attribute cache that caches method
6051 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006052
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006053- Bug #1776: __import__() no longer accepts filenames on any platform.
6054 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006055
Georg Brandlaed6c662008-01-07 17:25:53 +00006056- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6057
Georg Brandl3ee81df2008-05-17 18:14:43 +00006058- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6059 envvar and sys.dont_write_bytecode attribute. All these can be set
6060 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006061
Georg Brandl3ee81df2008-05-17 18:14:43 +00006062- Improve some exception messages when Windows fails to load an
6063 extension module. Now we get for example '%1 is not a valid Win32
6064 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006065
Georg Brandl3ee81df2008-05-17 18:14:43 +00006066- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006068- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6069 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006070
Christian Heimes0a8143f2007-12-18 23:22:54 +00006071- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006072 and INF. float("nan"), float("inf") and float("-inf") now work on
6073 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006074
Georg Brandl3ee81df2008-05-17 18:14:43 +00006075- Compiler now generates simpler and faster code for dictionary
6076 literals. The oparg for BUILD_MAP now indicates an estimated
6077 dictionary size. There is a new opcode, STORE_MAP, for adding
6078 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006079
Georg Brandl3ee81df2008-05-17 18:14:43 +00006080- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006085- Issue #1538: Avoid copying string in split/rsplit if the split char
6086 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006087
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006088- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006089 SystemError.
6090
Nick Coghlanef01d822007-12-03 12:55:17 +00006091- PEP 366: Allow explicit relative imports when executing modules

6093 __package__ attribute.
6094
Georg Brandl3ee81df2008-05-17 18:14:43 +00006095- Issue #1402: Fix a crash on exit, when another thread is still
6096 running, and if the deallocation of its frames somehow calls the
6097 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006098

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006102 attribute of an empty cell object.
6103
Georg Brandl3ee81df2008-05-17 18:14:43 +00006104- Issue #1460: The utf-7 incremental decoder did not accept truncated
6105 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006106
Georg Brandl3ee81df2008-05-17 18:14:43 +00006107- Patch #1739468: Directories and zipfiles containing a __main__.py
6108 file can now be directly executed by passing their name to the
6109 interpreter. The directory/zipfile is automatically inserted as the
6110 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006111
Georg Brandl3ee81df2008-05-17 18:14:43 +00006112- Issue #1265: Fix a problem with sys.settrace, if the tracing
6113 function uses a generator expression when at the same time the
6114 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006115
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006116- sets and frozensets now have an isdisjoint() method.
6117
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006118- optimize the performance of builtin.sum().
6119
Neal Norwitz44f326e2007-10-05 05:29:17 +00006120- Fix warnings found by the new version of the Coverity checker.
6121
Georg Brandl21e99f42010-03-07 15:23:59 +00006122- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006123 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6124 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006125
Georg Brandl3ee81df2008-05-17 18:14:43 +00006126- Issue #1686386: Tuple's tp_repr did not take into account the
6127 possibility of having a self-referential tuple, which is possible
6128 from C code. Nor did object's tp_str consider that a type's tp_str
6129 could do something that could lead to an inifinite recursion.
6130 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6131 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006132
Georg Brandl3ee81df2008-05-17 18:14:43 +00006133- Issue #1164: It was possible to trigger deadlock when using the
6134 'print' statement to write to a file since the GIL was not released
6135 as needed. Now PyObject_Print() does the right thing along with
6136 various tp_print implementations of the built-in types and those in
6137 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006138
Georg Brandl3ee81df2008-05-17 18:14:43 +00006139- Issue #1147: Exceptions were directly allowing string exceptions in
6140 their throw() method even though string exceptions no longer
6141 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006142
Georg Brandl3ee81df2008-05-17 18:14:43 +00006143- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00006146- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006147 PyObject_Call() never calling back out to Python code to trigger
6148 recursion depth updates/checks. Required the creation of a static
6149 RuntimeError instance in case normalizing an exception put the
6150 recursion check value past its limit. Fixes crashers
6151 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006152
Georg Brandl3ee81df2008-05-17 18:14:43 +00006153- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006166- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006167 __*__ attributes. (Some already existed, e.g., __doc__ and
6168 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006169
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006170- Add -3 option to the interpreter to warn about features that are
6171 deprecated and will be changed/removed in Python 3.0.
6172

6174 calls.
6175
Collin Winter62903052007-05-18 23:11:24 +00006176- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006177 "except E as target:". This is to provide forwards compatibility
6178 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006179
Brett Cannon229cee22007-05-05 01:34:02 +00006180- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006185- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006186 setting a plain string, ie don't expand to single letter identifiers.
6187
Raymond Hettinger13936692007-04-11 18:40:58 +00006188- Request #1191699: Slices can now be pickled.

6198
Guido van Rossum143b5642007-03-23 04:58:42 +00006199- Bug #1683368: The object.__init__() and object.__new__() methods are
6200 now stricter in rejecting excess arguments. The only time when
6201 either allows excess arguments is when it is not overridden and the
6202 other one is. For backwards compatibility, when both are
6203 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006204 warning later). Also, type.__init__() insists on the same signature
6205 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006206
Georg Brandl3ee81df2008-05-17 18:14:43 +00006207- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6208 object to complex using its __complex__() method before falling back
6209 to the __float__() method. Therefore, the functions in the cmath
6210 module now can operate on objects that define a __complex__()
6211 method.

6228
Georg Brandl7b9c5552007-03-12 14:30:05 +00006229- Bug #1678647: write a newline after printing an exception in any
6230 case, even when converting the value to a string failed.
6231
Georg Brandl871f1bc2007-03-12 13:17:36 +00006232- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006233 its argument, if it exists. If not, it will work like before. This
6234 allows customizing the output of dir() in the presence of a
6235 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006236
Collin Winter276887b2007-03-12 16:11:39 +00006237- Patch #922167: Python no longer segfaults when faced with infinitely
6238 self-recursive reload() calls (as reported by bug #742342).

6244 parthensized forms. This means complex(repr(x)) now works instead of
6245 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006246
Georg Brandlaa2321b2007-03-07 00:40:28 +00006247- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006248 makes the filenames the warning module prints much more sensible
6249 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006250

Georg Brandl0fca97a2007-03-05 22:28:08 +00006262- Patch #1674228: when assigning a slice (old-style), check for the
6263 sq_ass_slice instead of the sq_slice slot.
6264
Georg Brandl3ee81df2008-05-17 18:14:43 +00006265- When printing an unraisable error, don't print exceptions. before
6266 the name. This duplicates the behavior whening normally printing
6267 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006800 AttributeError instead of an IOError when the server's response

6892 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00007177- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7178 with RFC 3207 and forgets any knowledge obtained from the server not
7179 obtained from the TLS negotiation itself. Patch contributed by Bill
7180 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007181
Georg Brandl3ee81df2008-05-17 18:14:43 +00007182- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007183 that the SMTP.starttls() caller no longer needs to call ehlo()
7184 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007185 does not claim to support starttls. Adds the
7186 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7267 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7268 silently miscode subclasses of those types. Now, it raises a
7269 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007270

Georg Brandl3ee81df2008-05-17 18:14:43 +00007285 time so that opening a database previously created with the DB_DUP
7286 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7287 opens. Specifically: dictionary assignment to a DB object will
7288 replace all values for a given key when the database allows
7289 duplicate values. DB users should use DB.put(k, v) when they want
7290 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007291

7297 characters with ASCII value less than 32. Also, it correctly quotes
7298 dots only if they occur on a single line, as opposed to the previous
7299 behavior of quoting dots if they are the second character of any
7300 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007301

Georg Brandl3ee81df2008-05-17 18:14:43 +00007630- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7631 to ``PyTuple_SetItem``, it can be used to populate a brand new
7632 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007633
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007634- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007636- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7637 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7638 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007639
7640- Patch #1720595: add T_BOOL to the range of structmember types.
7641
7642- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7643 ``PyFloat_GetInfo()`` to the float API.
7644
Georg Brandl3ee81df2008-05-17 18:14:43 +00007645- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7646 of w# format code incorrectly truncated the length to an int, even
7647 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7648 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007649
Georg Brandl3ee81df2008-05-17 18:14:43 +00007650- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7651 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007652
Georg Brandl3ee81df2008-05-17 18:14:43 +00007653- PEP 3123: Provide forward compatibility with Python 3.0, while
7654 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7655 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007656
Georg Brandl3ee81df2008-05-17 18:14:43 +00007657- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7658 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007659
7660- Patch #1733960: Allow T_LONGLONG to accept ints.
7661
7662- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7663
Christian Heimes000a0742008-01-03 22:16:32 +00007664- Added a new API function ``PyImport_ImportModuleNoBlock``.
7665
Georg Brandl6caad7d2008-01-26 14:19:22 +00007666- Bug #1637022: Prefix AST symbols with _Py_.
7667
7668- Fix some leftovers from the conversion from int to Py_ssize_t
7669 (relevant to strings and sequences of more than 2**31 items).
7670
7671- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7672 outside of pystate.c and should not be necessary.
7673
Georg Brandl3ee81df2008-05-17 18:14:43 +00007674- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7675 absolute imports. In earlier versions they might have used relative
7676 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007677
Georg Brandl3ee81df2008-05-17 18:14:43 +00007678- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7679 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007680
Georg Brandl3ee81df2008-05-17 18:14:43 +00007681- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7682 macro so it can be used as an expression.

7687
Georg Brandl3ee81df2008-05-17 18:14:43 +00007688- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7689 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7690 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7691 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007692
Georg Brandl3ee81df2008-05-17 18:14:43 +00007693- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
7694 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00007704- buildtools now raises a DeprecationWarning.
7705
Georg Brandl3ee81df2008-05-17 18:14:43 +00007706- Removed the macfs module. It had been deprecated since Python 2.5.
7707 This lead to the deprecation of macostools.touched() as it relied
7708 solely on macfs and was a no-op under OS X.
