9Core and Builtins
10-----------------
11
Victor Stinner63c22fa2011-09-23 19:37:03 +020012- Issue #7732: Fix a crash on importing a module if a directory has the same
13 name than a Python module (e.g. "__init__.py"): don't close the file twice.
14
Mark Dickinsondbbed042011-09-19 16:38:08 +010015- Issue #12973: Fix overflow checks that invoked undefined behaviour in
16 int.__pow__. These overflow checks were causing int.__pow__ to produce
17 incorrect results with recent versions of Clang, as a result of the
Mark Dickinson4ac5d2c2011-09-19 19:23:55 +010018 compiler optimizing the check away. Also fix similar overflow check
19 in list_repeat (which caused test_list to fail with recent versions
20 of Clang).
Mark Dickinsondbbed042011-09-19 16:38:08 +010021

29 non-exception class.
Benjamin Petersonc3349cd2011-07-15 14:15:40 -050030
Antoine Pitrou16166452011-07-12 22:04:20 +020031- Issue #12149: Update the method cache after a type's dictionnary gets
32 cleared by the garbage collector. This fixes a segfault when an instance
33 and its type get caught in a reference cycle, and the instance's
34 deallocator calls one of the methods on the type (e.g. when subclassing
35 IOBase). Diagnosis and patch by Davide Rizzo.
36
Victor Stinnerba8b3a22011-07-08 02:07:45 +020037- Issue #12501: Adjust callable() warning: callable() is only not supported in
38 Python 3.1. callable() is again supported in Python 3.2.
39
Victor Stinner59729ff2011-07-05 11:28:19 +020040- Issue #9611, #9015: FileIO.read(), FileIO.readinto(), FileIO.write() and
41 os.write() clamp the length to INT_MAX on Windows.
42
Victor Stinnerd3c7e172011-05-30 23:49:13 +020043- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +020044 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
45 raw_input() interrupted by CTRL+c.
46
Barry Warsawc5643282011-07-19 17:06:30 -040047- dict_proxy objects now display their contents rather than just the class
48 name.

Lars Gustäbel8babfdf2011-09-05 17:04:18 +020063- Issue #12841: tarfile unnecessarily checked the existence of numerical user
64 and group ids on extraction. If one of them did not exist the respective id
65 of the current user (i.e. root) was used for the file and ownership
66 information was lost.
67
Éric Araujo429b8902011-08-30 01:48:59 +020068- Issue #10946: The distutils commands bdist_dumb, bdist_wininst and bdist_msi

158
Ned Deily87e82bb2011-06-28 19:52:59 -0700159- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
160 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
161 interpreter process. This could cause failures in non-Distutils subprocesses
162 and was unreliable since tests or user programs could modify the interpreter
163 environment after Distutils set it. Instead, have Distutils set the the
164 deployment target only in the environment of each build subprocess. It is
165 still possible to globally override the default by setting
166 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
167 greater or equal to the default value, the value with which the interpreter
168 was built.

175
R David Murrayf1138bb2011-06-17 22:23:04 -0400176- Issue #11700: mailbox proxy object close methods can now be called multiple
177 times without error, and _ProxyFile now closes the wrapped file.
178
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200179- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
180 connection if its getresponse() method fails with a socket error. Patch
181 written by Ezio Melotti.
182
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500183- Issue #9284: Allow inspect.findsource() to find the source of doctest
184 functions.
185

195
Barry Warsawc5643282011-07-19 17:06:30 -0400196- sys.setcheckinterval() now updates the current ticker count as well as
197 updating the check interval, so if the user decreases the check interval,
198 the ticker doesn't have to wind down to zero from the old starting point
199 before the new interval takes effect. And if the user increases the
200 interval, it makes sure the new limit takes effect right away rather have an
201 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00001073- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1074 This prevents user-created self-referencing ordered dictionaries from
1075 becoming permanently uncollectable GC garbage. The downside is that
1076 removing __del__ means that the internal doubly-linked list has to wait for
1077 GC collection rather than freeing memory immediately when the refcnt drops
1078 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001537- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1538 start byte and the continuation byte(s) are now considered invalid, instead
1539 of the number of bytes specified by the start byte.
1540 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1541 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1542 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1543 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001551- Issue #8748: Fix two issues with comparisons between complex and integer
1552 objects. (1) The comparison could incorrectly return True in some cases
1553 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1554 (2) The comparison raised an OverflowError for large integers, leading
1555 to unpredictable exceptions when combining integers and complex objects
1556 in sets or dicts.

Georg Brandlfee0f442010-05-22 21:26:21 +00001749- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1750 operation raises multiple signals and more than one of those signals is
1751 trapped, the specification determines the order in which the signals should be
1752 handled. In many cases this order wasn't being followed, leading to the wrong
1753 Python exception being raised.

1926 changed.

1939 with a non-empty format string. This is an effort to future-proof user
1940 code. If a derived class does not currently implement __format__ but later
1941 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001942 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001943 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001993- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1994 InvalidOperation instead of returning False. (Comparisons involving a quiet
1995 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1996 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001998- Issue #2531: Comparison operations between floats and Decimal instances now
1999 return a result based on the numeric values of the operands; previously they
2000 returned an arbitrary result based on the relative ordering of id(float) and
2001 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002003- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002004 argument `-` which tells it to read files to compile from stdin. Each line is
2005 read on demand and the named file is compiled immediately. (Original patch by
2006 Piotr Ożarowski).

2016 Fractions instance now raise TypeError instead of returning True/False. This
2017 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2018 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002122- Issue #1530559: When passing a non-integer argument to struct.pack with *any*

2127 the set of integer codes for which it was used differed between native packing
2128 and standard packing.)

2437 position to the given argument, which goes against the tradition of

2441 class used to represent files stored inside an archive. The new
2442 implementation is significantly faster and can be wrapped in a

2444 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002535- The ``__complex__()`` method is now looked up on the class of instances to
2536 make it consistent with other special methods.

2540
Mark Dickinson1b34d252010-01-01 17:27:30 +00002541- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002542 DeprecationWarning when passed a float argument where an integer was expected.
2543 These functions and methods now raise TypeError instead. The majority of the
2544 effects of this change are in the extension modules, but some core functions
2545 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2546 and many unicode/str methods.

2560 of integers: the result of a/b is now correctly rounded for ints a and b (at
2561 least on IEEE 754 platforms), and in particular does not depend on the
2562 internal representation of a long.

2570
Georg Brandlba83f822010-03-14 09:50:54 +00002571 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002708- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
2709 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002710
Georg Brandlba83f822010-03-14 09:50:54 +00002711- Issue #3382: 'F' formatting for float and complex now convert the result to
2712 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2713 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002714
Georg Brandlba83f822010-03-14 09:50:54 +00002715- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2716 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002717
Georg Brandlba83f822010-03-14 09:50:54 +00002718- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2719 1e-100 used to raise OverflowError, but now gives the requested 120
2720 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00002721
Georg Brandlba83f822010-03-14 09:50:54 +00002722- Add Py3k warnings for parameter names in parentheses.

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00002725
Georg Brandlba83f822010-03-14 09:50:54 +00002726- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
2727 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002728
Georg Brandlba83f822010-03-14 09:50:54 +00002729- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2730 decimal string that's guaranteed to round back to x under correct rounding
2731 (with round-half-to-even rounding mode). Previously it gave a string based on
2732 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2733 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2734 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002735
Georg Brandlba83f822010-03-14 09:50:54 +00002736- Issue #7117: On almost all platforms: float-to-string and string-to-float
2737 conversions within Python are now correctly rounded. Places these conversions
2738 occur include: str for floats and complex numbers; the float and complex
2739 constructors; old-style and new-style numeric formatting; serialization and
2740 deserialization of floats and complex numbers using marshal, pickle and json;
2741 parsing of float and imaginary literals in Python code; Decimal-to-float
2742 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002743
Georg Brandlba83f822010-03-14 09:50:54 +00002744 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2745 providing correctly-rounded strtod and dtoa C functions. This code is
2746 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2747 the C compiler. There may be a small number of platforms on which correct
2748 operation of this code cannot be guaranteed, so the code is not used: notably,
2749 this applies to platforms where the C double format is not IEEE 754 binary64,
2750 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2751 and Python's configure script is unable to determine how to change the FPU
2752 precision. On these platforms conversions use the platform strtod and dtoa,
2753 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002754
Georg Brandlba83f822010-03-14 09:50:54 +00002755- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2756 uses the correctly-rounded string <-> float conversions described above (when
2757 available), and so produces correctly rounded results that will display nicely
2758 under the float repr. There are two related small changes: (1) round now
2759 accepts any class with an ``__index__()`` method for its second argument (but
2760 no longer accepts floats for the second argument), and (2) an excessively
2761 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2762 raises an exception.

Philip Jenveyfab8be22009-11-17 02:42:26 +00002764- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
2765
Georg Brandlba83f822010-03-14 09:50:54 +00002766- Fix several issues with ``compile()``. The input can now contain Windows and
2767 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00002768
Georg Brandlba83f822010-03-14 09:50:54 +00002769- Remove length limitation when constructing a complex number from a unicode

2792 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +00002793
Georg Brandlba83f822010-03-14 09:50:54 +00002794- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
2795 and mutating it from another one. Patch by Scott Dial.

Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00002797- Issue #1571184: The Unicode database contains properties for more characters.
2798 The tables for code points representing numeric values, white spaces or line
2799 breaks are now generated from the official Unicode Character Database files,
2800 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00002909- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2910 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2911 but with at least one decimal point and with a default precision
2912 of 12. Previously, the behavior the same but with a default precision of 6.
2913 This more closely matches ``str()``, and reduces surprises when adding
2914 alignment flags to the empty presentation type. This also affects the new
2915 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00002924- Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3),
2925 '.5')`` now produces a sensible result.
Eric Smith9139cc62009-04-30 00:58:58 +00002926
Georg Brandlba83f822010-03-14 09:50:54 +00002927- Issue #5864: Fix empty format code formatting for floats so that it never
2928 gives more than the requested number of significant digits.
Mark Dickinson92fcc9c2009-04-29 20:41:00 +00002929
Georg Brandlba83f822010-03-14 09:50:54 +00002930- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes new

Martin v. Löwis99f27792009-04-26 00:53:18 +00002935
Eric Smith068f0652009-04-25 21:40:15 +00002936- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
2937 _PyOS_double_to_string or PyOS_double_to_string.
2938
Benjamin Peterson5083dc52009-04-25 00:41:22 +00002939- Issue #5283: Setting __class__ in __del__ caused a segfault.
2940
Georg Brandlba83f822010-03-14 09:50:54 +00002941- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves
2942 nans, infs or negative zeros.

Georg Brandlba83f822010-03-14 09:50:54 +00002950- Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no
2951 type code and we have an exponent.
Eric Smithaca19e62009-04-22 13:29:05 +00002952
Georg Brandlba83f822010-03-14 09:50:54 +00002953- Issue #3166: Make long -> float (and int -> float) conversions correctly

Georg Brandlba83f822010-03-14 09:50:54 +00002959- Issue #1869: Fix a couple of minor round() issues. ``round(5e15+1)`` was
2960 giving 5e15+2; ``round(-0.0)`` was losing the sign of the zero.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002979- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002980 untrackable objects are not tracked by the garbage collector. This can reduce
2981 the size of collections and therefore the garbage collection overhead on
2982 long-running programs, depending on their particular use of datatypes.
Antoine Pitrouf8387af2009-03-23 18:41:45 +00002983
Georg Brandlba83f822010-03-14 09:50:54 +00002984- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to improve its

Georg Brandlba83f822010-03-14 09:50:54 +00002988- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
2989 internal representation of integers, for performance reasons. Base 2**30 is
2990 enabled by default on 64-bit machines. Add --enable-big-digits option to
2991 configure, which overrides the default. Add sys.long_info structseq to
2992 provide information about the internal format.
Mark Dickinsonefc82f72009-03-20 15:51:55 +00002993
Benjamin Peterson6ffe8522009-03-18 20:52:15 +00002994- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
2995 result traceback.__members__ no longer exists.)
2996
Georg Brandlba83f822010-03-14 09:50:54 +00002997- Issue #4474: PyUnicode_FromWideChar now converts characters outside the BMP to
2998 surrogate pairs, on systems with sizeof(wchar_t) == 4 and sizeof(Py_UNICODE)
2999 == 2.
Mark Dickinson6b265f12009-03-18 16:07:26 +00003000
Georg Brandlba83f822010-03-14 09:50:54 +00003001- Issue #5237: Allow auto-numbered fields in str.format(). For example: ``'{}
3002 {}'.format(1, 2) == '1 2'``.
Eric Smith6f42edb2009-03-14 11:57:26 +00003003
Georg Brandlba83f822010-03-14 09:50:54 +00003004- Issue #3652: Make the 'line' argument for ``warnings.showwarning()`` a
Brett Cannon6c4cff02009-03-11 04:51:06 +00003005 requirement. Means the DeprecationWarning from Python 2.6 can go away.
3006
Georg Brandlba83f822010-03-14 09:50:54 +00003007- Issue #5247: Improve error message when unknown format codes are used when
3008 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00003009
Georg Brandlba83f822010-03-14 09:50:54 +00003010- Running Python with the -3 option now also warns about classic division for
3011 ints and longs.
Raymond Hettinger08259e82009-02-18 23:10:19 +00003012
Georg Brandlba83f822010-03-14 09:50:54 +00003013- Issue #5260: Long integers now consume less memory: average saving is 2 bytes
3014 per long on a 32-bit system and 6 bytes per long on a 64-bit system.
Mark Dickinson2ffb26f2009-02-15 10:13:41 +00003015
Antoine Pitrou76a4b892009-02-13 13:52:33 +00003016- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
3017 rotating the object pointer by 4 bits to the right.
3018
Georg Brandlba83f822010-03-14 09:50:54 +00003019- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs: it now
3020 forces its argument to double before testing for infinity.
Mark Dickinsonc97c9092009-02-09 14:18:43 +00003021
Benjamin Petersone18ef192009-01-20 14:21:16 +00003022- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
3023
Georg Brandl29c6a282009-04-05 20:23:13 +00003024- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00003025 were suppressing all exceptions. These include list(), filter(), map(),
3026 zip(), and bytearray().
3027
Benjamin Peterson596d3062009-01-19 15:42:23 +00003028- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
3029 functions.
3030
Benjamin Peterson5848d1f2009-01-19 00:08:08 +00003031- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
3032 OSError.
3033
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +00003034- Issue #4807: Port the _winreg module to Windows CE.
3035
Georg Brandlba83f822010-03-14 09:50:54 +00003036- Issue #4935: The overflow checking code in the expandtabs() method common to
3037 str, bytes and bytearray could be optimized away by the compiler, letting the
3038 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00003039
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00003040- Issue #3720: Fix a crash when an iterator modifies its class and removes its
3041 __next__ method.
3042

3046
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00003047- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
3048 collecting the oldest generation) so that allocating lots of objects without
3049 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00003050 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00003051 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

3054
Georg Brandlba83f822010-03-14 09:50:54 +00003055- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3056 existing .py counterpart, override the co_filename attributes of all code
3057 objects if the original filename is obsolete (which can happen if the file has
3058 been renamed, moved, or if it is accessed through different paths). Patch by
3059 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00003060
Georg Brandlba83f822010-03-14 09:50:54 +00003061- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00003063- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
3064 file with `str' filename on Windows.
3065
Antoine Pitrouaa687902009-01-01 14:11:22 +00003066- Issue #3680: Reference cycles created through a dict, set or deque iterator
3067 did not get collected.
3068
Georg Brandlba83f822010-03-14 09:50:54 +00003069- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
3070 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00003071
Benjamin Peterson7af65562008-12-29 17:56:58 +00003072- Issue #4764: With io.open, IOError.filename is set when trying to open a
3073 directory on POSIX systems.
3074
Benjamin Petersonfe231b02008-12-29 17:47:42 +00003075- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
3076 systems.
3077
Georg Brandl6425a2f2008-12-28 11:54:53 +00003078- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003079 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003080
Skip Montanarof205c132008-12-23 03:30:15 +00003081- Added test case to ensure attempts to read from a file opened for writing
3082 fail.
3083
Georg Brandlba83f822010-03-14 09:50:54 +00003084- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
3085 elapsed times, not only when some objects are uncollectable/unreachable.
3086 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00003087

Georg Brandlba83f822010-03-14 09:50:54 +00003098- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3099 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3100 instances. On a typical machine this saves 3 bytes of memory (on average) per
3101 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003102
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003103- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3104 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3105 instead of throwing a MemoryError.
3106
Georg Brandlba83f822010-03-14 09:50:54 +00003107- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3108 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003109
Benjamin Petersonc078f922008-11-21 22:27:24 +00003110- Issue #4367: Python would segfault during compiling when the unicodedata
3111 module couldn't be imported and \N escapes were present.
3112
Georg Brandlba83f822010-03-14 09:50:54 +00003113- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3114 file objects with closefd=False. The file descriptor is still kept open but
3115 the file object behaves like a closed file. The ``FileIO`` object also got a
3116 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003117
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003118- Issue #4348: Some bytearray methods returned that didn't cause any change to
3119 the bytearray, returned the same bytearray instead of a copy.
3120
Georg Brandlba83f822010-03-14 09:50:54 +00003121- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

3124
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003125- Issue #4048: The parser module now correctly validates relative imports.
3126
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003127- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

3134 __future__ import didn't work.
3135
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003136- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003137 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003138
Georg Brandlba83f822010-03-14 09:50:54 +00003139- On windows, ``os.chdir()`` given unicode was not working if
3140 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3141 this code path is really executed because I cannot move to such directory on
3142 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003143
Georg Brandlba83f822010-03-14 09:50:54 +00003144- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3145 element is temporarily replaced with an equivalent frozenset. But the
3146 eventual KeyError would always report the empty ``frozenset()`` as the missing
3147 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003148

4542
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004543- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4544
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004545- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4546 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4547 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4548 ``printf`` function, whereas PyString_FromFormat has an independent
4549 implementation and uses "%zd" on all platforms for size_t values.
4550 This makes a difference on win64, where ``printf`` needs "%Id" to display
4551 64bit values.
4552
Benjamin Peterson97179b02008-09-09 20:55:01 +00004553- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4554 error.
4555
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004556- Issue #3777: long() applied to a float object now always return a long
4557 object; previously an int would be returned for small values. the __long__
4558 method is allowed to return either an int or a long, but the behaviour of
4559 float objects should not change to respect backward compatibility.
4560
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004561- Issue #3751: str.rpartition would perform a left-partition when called with
4562 a unicode argument.
4563
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004564- Issue #3683: Fix compilation when --without-threads is given.
4565
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004566- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004567 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004568 was correctly parsed but parsing of subsequent arguments failed.
4569
Vinay Sajip35e3b032008-09-01 14:33:59 +00004570- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004571 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4572 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4573 when given a tuple of classes as second argument, were looking up
4574 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4575 type object.
4576
Neal Norwitz18aa3882008-08-24 05:04:52 +00004577- Fix crashes on memory allocation failure found with failmalloc.
4578
4579- Fix memory leaks found with valgrind and update suppressions file.
4580
4581- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4582
4583- Fix problem using wrong name in decimal module reported by pychecker.
4584
Christian Heimes7d4c3172008-08-22 19:47:25 +00004585- Silenced another compiler warning about a used but not defined
4586 function 'stringlib_contains_obj'.
4587
Benjamin Peterson712ee922008-08-24 18:10:20 +00004588- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
4589 ``__delslice__``.
4590
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004591- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4592 library targets in the Makefile.
4593
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004594- Issue #1204: The configure script now tests for additional libraries
4595 that may be required when linking against readline. This fixes issues
4596 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
4597

4605
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00004606- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
4607 stack usage in the case of deeply nested objects.
4608
Guido van Rossume3c4fd92008-09-10 14:27:00 +00004609- Issue #3629: Fix sre "bytecode" validator for an end case.
4610
Martin v. Löwis24329ba2008-09-10 13:38:12 +00004611- Issue #3811: The Unicode database was updated to 5.1.
4612
Nick Coghland2e09382008-09-11 12:11:06 +00004613- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
4614 silent misbehaviour when a single instance is nested in multiple
4615 with statements, or when the methods are invoked in the wrong order.
4616
Vinay Sajip844f7412008-09-09 13:42:08 +00004617- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
4618
Nick Coghland2e09382008-09-11 12:11:06 +00004619- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004620 return a list or None rather than a custom object.
4621
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004622- Issue #1638033: Cookie.Morsel gained the httponly attribute.
4623
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00004624- Issue #3535: zipfile couldn't read some zip files larger than 2GB.
4625
4626- Issue #3776: Deprecate the bsddb package for removal in 3.0.
Brett Cannon32476fc2008-09-05 18:33:51 +00004627
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +00004628- Issue #3762: platform.architecture() fails if python is lanched via
4629 its symbolic link.
4630
Vinay Sajip65d66e12008-09-04 07:31:21 +00004631- Issue #3772: Fixed regression problem in StreamHandler.emit().

Facundo Batistac585df92008-09-03 22:35:50 +00004634 to the urlparse one. Added a PendingDeprecationWarning in the old
4635 module, it will be deprecated in the future.
4636
Marc-André Lemburgb339b2a2008-09-03 11:13:56 +00004637- Issue #2562: Fix distutils PKG-INFO writing logic to allow having

4643 path to the Python binary.
4644
Georg Brandl222e2082010-08-01 22:27:39 +00004645- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00004646 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4647 for catch_warnings() also led to an improvement in the raising of a
4648 DeprecationWarning related to warnings.warn_explicit().
4649
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004650- The deprecation warnings for the old camelCase threading API were removed.
4651
Vinay Sajip35e3b032008-09-01 14:33:59 +00004652- logging: fixed lack of use of encoding attribute specified on a stream.
4653
Christian Heimesa27a62e2008-08-22 19:55:54 +00004654- Silenced a trivial compiler warning in the sqlite module.
4655
Christian Heimes1cc69632008-08-22 20:10:27 +00004656- Fixed two format strings in the _collections module.
4657
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004658- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a
4659 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00004660
Gregory P. Smithd7122032008-09-02 05:36:11 +00004661- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
4662 non-integer floating point number.
4663
Vinay Sajip65d66e12008-09-04 07:31:21 +00004664- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

4669
Jesse Noller438195f2009-01-18 21:04:36 +00004670- Issue #4301: Patch the logging module to add processName support, remove
4671 _check_logger_class from multiprocessing.
4672
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004673- Issue #2975: When compiling several extension modules with Visual Studio 2008
4674 from the same python interpreter, some environment variables would grow
4675 without limit.
4676
Benjamin Peterson37346b22008-08-23 20:27:43 +00004677- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4678 exploitation of poor argument checking.
4679
Gerhard Häringef2276b2008-09-12 13:54:06 +00004680- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4681
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004682- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4683 remaining ones have "pysqlite_" prefix.
4684
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004685- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

4691
Nick Coghland2e09382008-09-11 12:11:06 +00004692- Issue #3781: Add test.test_support.check_warnings() as a convenience
4693 wrapper for warnings.catch_warnings() that makes it easier to check
4694 that expected warning messages are being reported.
4695
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00004696- Issue #3796: Some tests functions were not enabled in test_float.
4697

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004714What's New in Python 2.6 beta 3?
4715================================
4716
Barry Warsaw07a4a382008-08-21 01:15:08 +00004717*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004718
4719Core and Builtins
4720-----------------
4721
Guido van Rossumf8402962008-08-20 15:01:50 +00004722- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4723 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4724 extensions do not automatically benefit from the class attribute
4725 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4726 to their tp_flags field if they care. This is a backwards
4727 compatibility feature; in 3.0, all types will use the cache by
4728 default.
4729
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004730- Keyword arguments can now follow starred arguments. (``f(a, *args,
4731 keyword=23)`` is now valid syntax.)
4732
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004733- ctypes function pointers that are COM methods have a boolean True
4734 value again.
4735
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004736- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4737 by denying s# to parse objects that have a releasebuffer procedure,
4738 and introducing s*.
4739
Georg Brandl1e13ea92008-08-11 09:07:59 +00004740- Issue #3537: Fix an assertion failure when an empty but presized dict
4741 object was stored in the freelist.
4742
Mark Dickinsonb6467572008-08-04 21:30:09 +00004743- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4744 ValueError consistently across platforms.
4745
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004746- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4747 (64bit Unix, for example), unichr() would truncate its argument and return
4748 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4749
Neal Norwitze7d8be82008-07-31 17:17:14 +00004750- Apply security patches from Apple.
4751
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004752- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4753 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4754
Antoine Pitrou92f82162008-07-25 22:22:08 +00004755- Issue #1819: function calls with several named parameters are now on
4756 average 35% faster (as measured by pybench).
4757
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004758- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4759 the python debugger steps into a class statement: the free variables (local
4760 variables defined in an outer scope) would be deleted from the outer scope.
4761
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004762- Issue #2620: Overflow checking when allocating or reallocating memory
4763 was not always being done properly in some python types and extension
4764 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4765 all been updated to perform better checks and places in the code that
4766 would previously leak memory on the error path when such an allocation
4767 failed have been fixed.
4768
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004769Library
4770-------
4771
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004772- Issue #3612: Added some missing basic types in ctypes.wintypes.
4773
Benjamin Petersone977ad42008-08-20 01:42:01 +00004774- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4775 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4776
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004777- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4778 version reported by these tools does not necessarily follow the python
4779 version numbering scheme, so the module is less strict when parsing it.
4780
Nick Coghlanf70385a2008-08-18 12:42:46 +00004781- Issue #2235: Added Py3k warnings for types which will become unhashable
4782 under the stricter __hash__ inheritance rules in 3.0. Several types
4783 which did not meet the rules for hash invariants and were already
4784 unhashable in 3.0 have now been explicitly flagged as unhashable in
4785 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4786 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4787
Brett Cannon88f801d2008-08-18 00:46:22 +00004788- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4789 imported into the module but exposed as part of the module's API.
4790
Brett Cannon7b96f072008-08-18 00:41:11 +00004791- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004795- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4796
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004797- Issue #3575: Incremental decoder's decode function now takes bytearray
4798 by using 's*' instead of 't#'.
4799
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004800- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004801 fails unicode conversion on 2nd parameter. (windows only)
4802
Georg Brandl222e2082010-08-01 22:27:39 +00004803- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004804 in a redirect.
4805
Brett Cannonabe423e2008-08-16 21:47:07 +00004806- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004807 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004808
Facundo Batistaeb90b782008-08-16 14:44:07 +00004809- Issue #2776: fixed small issue when handling an URL with double slash
4810 after a 302 response in the case of not going through a proxy.
4811
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004812- Issue #2676: in the email package, content-type parsing was hanging on
4813 pathological input because of quadratic or exponential behaviour of a
4814 regular expression.
4815
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004816- Issue #3476: binary buffered reading through the new "io" library is now
4817 thread-safe.
4818
Brett Cannonbf3157b2008-08-14 05:00:03 +00004819- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4820 since mimetools itself is deprecated. Because modules are cached, all
4821 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4822
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004823- Issue #3134: shutil referenced undefined WindowsError symbol.
4824
Robert Schuppenies14646332008-08-10 11:01:53 +00004825- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4826 menu entries were not deleted.

Antoine Pitroude781a42008-08-09 12:43:23 +00004857 asking for a specific length. This problem only affected files opened

4901
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004902- Issue #643841: The language reference now provides more detailed
4903 coverage of the lookup process for special methods. The disclaimers
4904 regarding lack of coverage of new-style classes have also been

4914-----------------
4915
Georg Brandl3e483f62008-07-16 22:57:41 +00004916- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4917 its methods now allow for items objects that can be converted to
4918 an integer using operator.index().
4919
Mark Dickinson64b7e502008-07-16 09:40:03 +00004920- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4921 produced a ValueError instead of giving the correct float.
4922
Eric Smitha5fa5a22008-07-16 00:11:49 +00004923- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4924 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4925
Mark Dickinson7103aa42008-07-15 19:08:33 +00004926- Issue #3008: the float type has a new instance method 'float.hex'
4927 and a new class method 'float.fromhex' to convert floating-point
4928 numbers to and from hexadecimal strings, respectively.
4929
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004930- Issue #2235: __hash__ is once again inherited by default. To allow
4931 collections.Hashable to remain meaningful in the presence of the
4932 default hash implementation (object.__hash__), it is now possible
4933 to explicit block inheritance of hash by setting __hash__=None at
4934 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4935 level.
4936
Nick Coghlanb028f502008-07-13 14:52:36 +00004937- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4938 the parent module cannot be found while performing an absolute import.
4939 This means that an incorrectly defined __package__ attribute will
4940 now only prevent relative imports in that module rather than causing
4941 all imports from that module to fail.
4942
Nick Coghlan14ff9942008-07-08 14:21:42 +00004943- Issue #2517: Allow unicode messages in Exceptions again by correctly

4953 another thread's dictionary.
4954
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004955- Issue #3004: Minor change to slice.indices(): the start and stop
4956 arguments are now treated identically, making the behaviour easier
4957 to describe and understand. For example, slice(None, -10,
4958 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4959 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4960 10, -1).
4961
Georg Brandl278fc502008-07-19 12:46:12 +00004962- Issue #3219: Calling a function with repeated keyword arguments,
4963 f(a=2, a=23), would not cause a syntax error. This was a regression
4964 from 2.4 caused by the switch to the new compiler.

4967 other freelists. Changes their CompactFreeList apis into

4975 error when they failed.
4976
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004977- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005002- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5003 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005004 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005005 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005021- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5394 an extension. This was added for compatibility with Apple's build
5395 of Python.
5396
5397- The bundled OSX-specific copy of libbffi is now in sync with the version
5398 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
5399
Georg Brandl25c34082008-08-18 23:09:49 +00005400- The threading module gained aliases for names that will be removed in the
5401 3.x series.

5409
Brett Cannonb61d8012008-05-11 23:39:04 +00005410- ``Lib/lib-old`` is now added to sys.path.
5411
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005412- On MacOS X it is now possible to install the framework in 64-bit
5413 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005414 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005415
5416 This is controlled by the configure argument ``--with-universal-archs``:
5417
5418 - ``--with-universal-archs=all``: install 4-way universal
5419
5420 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5421
5422 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5423
5424 This option should be used in combination with ``--enable-universalsdk=``.
5425
5426 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00005435
5436- The PyString functions have been renamed to PyBytes. A batch of
5437 defines were added so that the linker still sees the original
5438 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005476- Issue #1631171: Re-implement the 'warnings' module in C (the
5477 original Python code has been kept as backup). This will allow for
5478 using the 'warning's machinery in such places as the parser where
5479 use of pure Python code is not possible. Both the ``showarning()``
5480 and ``formatwarning()`` gain an optional 'line' argument which is
5481 not called by default for backwards-compatibility reasons. Setting
5482 ``warnings.showwarning()`` to an implementation that lacks support
5483 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005508- The getpass module has been improved on Unix. It now uses /dev/tty
5509 by default and uses stderr instead of stdout. A GetPassWarning is
5510 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005525- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005526 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005546- Issue #2550: The approach used by client/server code for obtaining
5547 ports to listen on in network-oriented tests has been refined in an
5548 effort to facilitate running multiple instances of the entire
5549 regression test suite in parallel without issue.
5550 test_support.bind_port() has been fixed such that it will always
5551 return a unique port -- which wasn't always the case with the
5552 previous implementation, especially if socket options had been set
5553 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5554 new implementation of bind_port() will actually raise an exception
5555 if it is passed an AF_INET/SOCK_STREAM socket with either the
5556 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5557 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5558 the socket it's been passed. This currently only applies to
5559 Windows. This option prevents any other sockets from binding to the
5560 host/port we've bound to, thus removing the possibility of the
5561 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5562 when a second SOCK_STREAM socket binds and accepts to a host/port
5563 that's already been bound by another socket. The optional preferred
5564 port parameter to bind_port() has been removed. Under no
5565 circumstances should tests be hard coding ports!
5566
5567 test_support.find_unused_port() has also been introduced, which will
5568 pass a temporary socket object to bind_port() in order to obtain an
5569 unused port. The temporary socket object is then closed and
5570 deleted, and the port is returned. This method should only be used
5571 for obtaining an unused port in order to pass to an external program
5572 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5573 a parameter to a server-oriented class that doesn't give you direct
5574 access to the underlying socket used.
5575
5576 Finally, test_support.HOST has been introduced, which should be used
5577 for the host argument of any relevant socket calls (i.e. bind and
5578 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005579
5580 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005581 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005582 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5583 test_asynchat and test_socket_ssl.
5584
Georg Brandl3ee81df2008-05-17 18:14:43 +00005585 It is now possible for multiple instances of the regression test
5586 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00005855- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005856 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00005865- Added the future_builtins module, which contains hex() and oct().
5866 These are the PEP 3127 version of these functions, designed to be
5867 compatible with the hex() and oct() builtins from Python 3.0. They
5868 differ slightly in their output formats from the existing, unchanged
5869 Python 2.6 builtins. The expected usage of the future_builtins
5870 module is:
5871 from future_builtins import hex, oct
5872
Eric Smith7ef40bf2008-02-20 23:34:22 +00005873- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5874 exponents for exponents with absolute value < 100. Follows C99
5875 standard. This is a change on Windows, which would use 3 digits.
5876 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5877 so that any alterations it does to the resulting string will be
5878 available in stringlib/formatter.h (for float.__format__).
5879
Eric Smith5a3c1352008-02-19 13:21:56 +00005880- Implemented PEP 3101, Advanced String Formatting. This adds a new
5881 builtin format(); a format() method for str and unicode; a
5882 __format__() method to object, str, unicode, int, long, float, and
5883 datetime; the class string.Formatter; and the C API
5884 PyObject_Format().
5885
Georg Brandl3ee81df2008-05-17 18:14:43 +00005886- Fixed several potential crashes, all caused by specially crafted
5887 __del__ methods exploiting objects in temporarily inconsistent
5888 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005889
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005890- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005891 prevent a possible crash: an Abstract Base Class would try to access
5892 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005893

5898 in order to allow pymalloc to free more arenas. Python may give back
5899 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005900
Georg Brandl3ee81df2008-05-17 18:14:43 +00005901- Issue #2045: Fix an infinite recursion triggered when printing a
5902 subclass of collections.defaultdict, if its default_factory is set
5903 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005904
Christian Heimesf75dbef2008-02-08 00:11:31 +00005905- Fixed a minor memory leak in dictobject.c. The content of the free
5906 list was not freed on interpreter shutdown.
5907
Georg Brandl21e99f42010-03-07 15:23:59 +00005908- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00005910
Georg Brandl3ee81df2008-05-17 18:14:43 +00005911- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5912 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005913 to compact the internal free lists of pre-allocted ints and floats.
5914
Georg Brandl3ee81df2008-05-17 18:14:43 +00005915- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5916 calls. Python expected the return type int but the fork familie
5917 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005918
Georg Brandl3ee81df2008-05-17 18:14:43 +00005919- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5920 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005921
Georg Brandl3ee81df2008-05-17 18:14:43 +00005922- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5923 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005924
Georg Brandl3ee81df2008-05-17 18:14:43 +00005925- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5926 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00005928- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5929 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005930
Georg Brandl3ee81df2008-05-17 18:14:43 +00005931- Patch #1473257: generator objects gain a gi_code attribute. This is
5932 the same object as the func_code attribute of the function that
5933 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005934
Georg Brandl3ee81df2008-05-17 18:14:43 +00005935- Issue #1920: "while 0" statements were completely removed by the
5936 compiler, even in the presence of an "else" clause, which is
5937 supposed to be run when the condition is false. Now the compiler
5938 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005939
Guido van Rossumeead05f2008-01-24 18:21:02 +00005940- A few crashers fixed: weakref_in_del.py (issue #1377858);
5941 loosing_dict_ref.py (issue #1303614, test67.py);
5942 borrowed_ref_[34].py (not in tracker).
5943
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005944- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005945 suppressed while an extension is loaded by calling SetErrorMode in
5946 dynload_win.c. The error is still reported properly.
5947
Georg Brandl3ee81df2008-05-17 18:14:43 +00005948- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005949 several extension methods and modules do not work without unicode
5950 support.
5951
Georg Brandl26543b12008-01-21 18:36:51 +00005952- Issue #1882: when compiling code from a string, encoding cookies in the
5953 second line of code were not always recognized correctly.
5954
Georg Brandl14404b62008-01-19 19:27:05 +00005955- Issue #1679: "0x" was taken as a valid integer literal.
5956
Georg Brandl6caad7d2008-01-26 14:19:22 +00005957- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005958 added.
5959
Christian Heimesc94e2b52008-01-14 04:13:37 +00005960- sys.float_info / PyFloat_GetInfo: The floating point information
5961 object was converted from a dict to a specialized structseq object.
5962
Georg Brandl3ee81df2008-05-17 18:14:43 +00005963- Patch #1816: Added sys.flags structseq. It exposes the status of
5964 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005965
Georg Brandl3ee81df2008-05-17 18:14:43 +00005966- Objects/structseq.c: Implemented new structseq representation. The
5967 patch makes structseqs (e.g. the return value of os.stat) more
5968 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005969
Georg Brandl3ee81df2008-05-17 18:14:43 +00005970- Patch #1700288: added a type attribute cache that caches method
5971 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005972
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005973- Bug #1776: __import__() no longer accepts filenames on any platform.
5974 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005975
Georg Brandlaed6c662008-01-07 17:25:53 +00005976- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5977
Georg Brandl3ee81df2008-05-17 18:14:43 +00005978- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5979 envvar and sys.dont_write_bytecode attribute. All these can be set
5980 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005981
Georg Brandl3ee81df2008-05-17 18:14:43 +00005982- Improve some exception messages when Windows fails to load an
5983 extension module. Now we get for example '%1 is not a valid Win32
5984 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005985

Christian Heimes0a8143f2007-12-18 23:22:54 +00005991- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005992 and INF. float("nan"), float("inf") and float("-inf") now work on
5993 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005994
Georg Brandl3ee81df2008-05-17 18:14:43 +00005995- Compiler now generates simpler and faster code for dictionary
5996 literals. The oparg for BUILD_MAP now indicates an estimated
5997 dictionary size. There is a new opcode, STORE_MAP, for adding
5998 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006027- Patch #1739468: Directories and zipfiles containing a __main__.py
6028 file can now be directly executed by passing their name to the
6029 interpreter. The directory/zipfile is automatically inserted as the
6030 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006031
Georg Brandl3ee81df2008-05-17 18:14:43 +00006032- Issue #1265: Fix a problem with sys.settrace, if the tracing
6033 function uses a generator expression when at the same time the
6034 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006035
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006036- sets and frozensets now have an isdisjoint() method.
6037
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006038- optimize the performance of builtin.sum().
6039
Neal Norwitz44f326e2007-10-05 05:29:17 +00006040- Fix warnings found by the new version of the Coverity checker.
6041
Georg Brandl21e99f42010-03-07 15:23:59 +00006042- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006043 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6044 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006045
Georg Brandl3ee81df2008-05-17 18:14:43 +00006046- Issue #1686386: Tuple's tp_repr did not take into account the
6047 possibility of having a self-referential tuple, which is possible
6048 from C code. Nor did object's tp_str consider that a type's tp_str
6049 could do something that could lead to an inifinite recursion.
6050 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6051 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006052
Georg Brandl3ee81df2008-05-17 18:14:43 +00006053- Issue #1164: It was possible to trigger deadlock when using the
6054 'print' statement to write to a file since the GIL was not released
6055 as needed. Now PyObject_Print() does the right thing along with
6056 various tp_print implementations of the built-in types and those in
6057 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006058
Georg Brandl3ee81df2008-05-17 18:14:43 +00006059- Issue #1147: Exceptions were directly allowing string exceptions in
6060 their throw() method even though string exceptions no longer
6061 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006062
Georg Brandl3ee81df2008-05-17 18:14:43 +00006063- Issue #1096: Prevent a segfault from getting the repr of a very
6064 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006065
Brett Cannon1e534b52007-09-07 04:18:30 +00006066- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006067 PyObject_Call() never calling back out to Python code to trigger
6068 recursion depth updates/checks. Required the creation of a static
6069 RuntimeError instance in case normalizing an exception put the
6070 recursion check value past its limit. Fixes crashers
6071 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006072

Neal Norwitz0ac60192007-05-27 04:08:54 +00006086- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006087 __*__ attributes. (Some already existed, e.g., __doc__ and
6088 __name__.)

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006090- Add -3 option to the interpreter to warn about features that are
6091 deprecated and will be changed/removed in Python 3.0.
6092
Georg Brandl2134e752007-05-21 20:34:16 +00006093- Patch #1686487: you can now pass any mapping after '**' in function
6094 calls.
6095
Collin Winter62903052007-05-18 23:11:24 +00006096- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006097 "except E as target:". This is to provide forwards compatibility
6098 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00006100- Deprecate BaseException.message as per PEP 352.
6101
Georg Brandl3ee81df2008-05-17 18:14:43 +00006102- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006103 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006105- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006106 setting a plain string, ie don't expand to single letter identifiers.
6107
Raymond Hettinger13936692007-04-11 18:40:58 +00006108- Request #1191699: Slices can now be pickled.
6109
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006110- Request #1193128: str.translate() now allows a None argument for
6111 translations that only remove characters without re-mapping the
6112 remaining characters.
6113
Georg Brandl5cb76c12007-03-21 09:00:39 +00006114- Patch #1682205: a TypeError while unpacking an iterable is no longer
6115 masked by a generic one with the message "unpack non-sequence".
6116
Neal Norwitzaa754b72007-03-21 06:39:48 +00006117- Remove unused file Python/fmod.c.
6118
Guido van Rossum143b5642007-03-23 04:58:42 +00006119- Bug #1683368: The object.__init__() and object.__new__() methods are
6120 now stricter in rejecting excess arguments. The only time when
6121 either allows excess arguments is when it is not overridden and the
6122 other one is. For backwards compatibility, when both are
6123 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006124 warning later). Also, type.__init__() insists on the same signature
6125 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006127- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6128 object to complex using its __complex__() method before falling back
6129 to the __float__() method. Therefore, the functions in the cmath
6130 module now can operate on objects that define a __complex__()
6131 method.

Georg Brandl871f1bc2007-03-12 13:17:36 +00006152- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006153 its argument, if it exists. If not, it will work like before. This
6154 allows customizing the output of dir() in the presence of a
6155 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00006167- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl4e933132006-09-06 20:05:58 +00006270- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006679 the client's request was successfully received, understood, and

6812 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00007205 time so that opening a database previously created with the DB_DUP
7206 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7207 opens. Specifically: dictionary assignment to a DB object will
7208 replace all values for a given key when the database allows
7209 duplicate values. DB users should use DB.put(k, v) when they want
7210 to store duplicates; not DB[k] = v.

7217 characters with ASCII value less than 32. Also, it correctly quotes
7218 dots only if they occur on a single line, as opposed to the previous
7219 behavior of quoting dots if they are the second character of any
7220 line.
