Antoine Pitrou16166452011-07-12 22:04:20 +0200135- Issue #12149: Update the method cache after a type's dictionnary gets
136 cleared by the garbage collector. This fixes a segfault when an instance
137 and its type get caught in a reference cycle, and the instance's
138 deallocator calls one of the methods on the type (e.g. when subclassing
139 IOBase). Diagnosis and patch by Davide Rizzo.

Victor Stinner08563d92011-05-30 23:44:13 +0200148 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
149 raw_input() interrupted by CTRL+c.
150
Łukasz Langa7a153902011-10-18 17:16:00 +0200151- Issue #10860: httplib now correctly handles an empty port after port
152 delimiter in URLs.
153

Florent Xiclunac2279652012-02-12 14:49:03 +0100192- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100193 has left two versions of customize_compiler, the original in
194 distutils.sysconfig and another copy in distutils.ccompiler, with some
195 parts of distutils calling one and others using the other.
196 Complete the revert back to only having one in distutils.sysconfig as
197 is the case in 3.x.
198
Ned Deily0d0ea482012-02-10 12:59:06 +0100199- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
200 Distutils-based packages with C extension modules may fail because
201 Apple has removed gcc-4.2, the version used to build python.org
202 64-bit/32-bit Pythons. If the user does not explicitly override
203 the default C compiler by setting the CC environment variable,
204 Distutils will now attempt to compile extension modules with clang
205 if gcc-4.2 is required but not found. Also as a convenience, if
206 the user does explicitly set CC, substitute its value as the default
207 compiler in the Distutils LDSHARED configuration variable for OS X.
208 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
209 SDK, neither of which are available in Xcode 4. This change does not
210 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700483- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
484 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
485 interpreter process. This could cause failures in non-Distutils subprocesses
486 and was unreliable since tests or user programs could modify the interpreter
487 environment after Distutils set it. Instead, have Distutils set the the
488 deployment target only in the environment of each build subprocess. It is
489 still possible to globally override the default by setting
490 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
491 greater or equal to the default value, the value with which the interpreter
492 was built.

Barry Warsawc5643282011-07-19 17:06:30 -0400520- sys.setcheckinterval() now updates the current ticker count as well as
521 updating the check interval, so if the user decreases the check interval,
522 the ticker doesn't have to wind down to zero from the old starting point
523 before the new interval takes effect. And if the user increases the
524 interval, it makes sure the new limit takes effect right away rather have an
525 early task switch before recognizing the new interval.

1473 GC collection rather than freeing memory immediately when the refcnt drops
1474 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001933- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1934 start byte and the continuation byte(s) are now considered invalid, instead
1935 of the number of bytes specified by the start byte.
1936 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1937 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1948 objects. (1) The comparison could incorrectly return True in some cases
1949 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1950 (2) The comparison raised an OverflowError for large integers, leading

2092 non-float non-integer argument is now converted to an integer (if possible)

Georg Brandlfee0f442010-05-22 21:26:21 +00002293- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002294 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2295 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2296 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2316Core and Builtins
2317-----------------
2318
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002319- Issue #7301: Add environment variable $PYTHONWARNINGS.
2320
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002321- Issue #8329: Don't return the same lists from select.select when no fds are
2322 changed.
2323
Georg Brandlfee0f442010-05-22 21:26:21 +00002324- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002325 on 64-bit machines. The shift count for either left or right shift is
2326 permitted to be up to sys.maxsize.
2327
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002328- Ensure that tokenization of identifiers is not affected by locale.
2329
Georg Brandlfee0f442010-05-22 21:26:21 +00002330- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002331
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002332- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2333
Georg Brandlfee0f442010-05-22 21:26:21 +00002334- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2335 with a non-empty format string. This is an effort to future-proof user
2336 code. If a derived class does not currently implement __format__ but later
2337 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002338 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002339 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002340
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002341- Issue #8268: Old-style classes (not just instances) now support weak

Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002352- Issue #8164: Don't allow lambda functions to have a docstring.
2353
Victor Stinner66644262010-03-10 22:30:19 +00002354- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002355 (SIGINT). If an error occurs while importing the site module, the error is
2356 printed and Python exits. Initialize the GIL before importing the site

2371
Georg Brandlfee0f442010-05-22 21:26:21 +00002372- Issue #8257: The Decimal construct now accepts a float instance directly,
2373 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002374
2375 >>> Decimal(1.1)
2376 Decimal('1.100000000000000088817841970012523233890533447265625')
2377
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002378- collections.Counter() now supports a subtract() method.
2379
Georg Brandlfee0f442010-05-22 21:26:21 +00002380- The functools module now has a total_ordering() class decorator to simplify
2381 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002382
Georg Brandlfee0f442010-05-22 21:26:21 +00002383- The functools module also adds cmp_to_key() as a tool to transition old-style
2384 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002385
Georg Brandlfee0f442010-05-22 21:26:21 +00002386- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2387 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002388
Georg Brandlfee0f442010-05-22 21:26:21 +00002389- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2390 InvalidOperation instead of returning False. (Comparisons involving a quiet
2391 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2392 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002393
Georg Brandlfee0f442010-05-22 21:26:21 +00002394- Issue #2531: Comparison operations between floats and Decimal instances now
2395 return a result based on the numeric values of the operands; previously they
2396 returned an arbitrary result based on the relative ordering of id(float) and
2397 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002398
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002399- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002400 argument `-` which tells it to read files to compile from stdin. Each line is
2401 read on demand and the named file is compiled immediately. (Original patch by
2402 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002403
Georg Brandlfee0f442010-05-22 21:26:21 +00002404- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002407- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2408 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002409 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002410
Georg Brandlfee0f442010-05-22 21:26:21 +00002411- Comparisons using one of <, <=, >, >= between a complex instance and a
2412 Fractions instance now raise TypeError instead of returning True/False. This
2413 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2414 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002415

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002425- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002426 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Antoine Pitroubb445a12010-02-05 17:05:54 +00002755- Issue #5677: Explicitly forbid write operations on read-only file objects,
2756 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002757 library would return a bogus result; on Solaris, it was possible to crash the
2758 interpreter. Patch by Stefan Krah.

2769 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +00002770
Georg Brandlba83f822010-03-14 09:50:54 +00002771- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2772 and add the additional members returned in an OSVERSIONINFOEX structure. The
2773 new members are service_pack_major, service_pack_minor, suite_mask, and
2774 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00002776- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2777 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2778 returning NULL. The macro now returns a statically allocated empty string
2779 instead.

2789 strings,
2790 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2791 numeric strings corresponding to subnormal values,
2792 (3) a memory leak for some values large enough to cause overflow, and
2793 (4) a number of flaws that could lead to incorrectly rounded results.
2794

2811 interpreter shutdown.
2812
Georg Brandlba83f822010-03-14 09:50:54 +00002813- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
2814 XML processing instructions and comments. These raw characters are allowed
2815 by the XML specification, and are necessary when outputting e.g. PHP code in
2816 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00002824- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002825 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002826 Also, raise ValueError rather than TypeError when an unknown TIPC address
2827 type is specified. Patch by Brian Curtin.
2828
Vinay Sajip28c382f2010-02-04 18:48:53 +00002829- logging: Implemented PEP 391.
2830
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002831- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002832 file position when calling `truncate()`. It would previously change the file
2833 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002834 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2835
Georg Brandlba83f822010-03-14 09:50:54 +00002836- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2837 class used to represent files stored inside an archive. The new
2838 implementation is significantly faster and can be wrapped in a
2839 ``io.BufferedReader`` object for more speedups. It also solves an issue
2840 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2841 Patch by Nir Aides.

2849 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00002850
Georg Brandlba83f822010-03-14 09:50:54 +00002851- Issue #7748: Since unicode values are supported for some metadata options in
2852 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2853 encoded string for them. This ensures that the upload and register commands
2854 send the correct values to PyPI without any error.

2930
Georg Brandlba83f822010-03-14 09:50:54 +00002931- The ``__complex__()`` method is now looked up on the class of instances to
2932 make it consistent with other special methods.

2936
Mark Dickinson1b34d252010-01-01 17:27:30 +00002937- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002938 DeprecationWarning when passed a float argument where an integer was expected.
2939 These functions and methods now raise TypeError instead. The majority of the
2940 effects of this change are in the extension modules, but some core functions
2941 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2942 and many unicode/str methods.

2966
Georg Brandlba83f822010-03-14 09:50:54 +00002967 These executables now work properly with the arch(1) command: ``arch -ppc
2968 python`` will start a universal binary version of python in PPC mode (unlike
2969 previous releases).

3109 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003110
Georg Brandlba83f822010-03-14 09:50:54 +00003111- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3112 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003113
Georg Brandlba83f822010-03-14 09:50:54 +00003114- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3115 1e-100 used to raise OverflowError, but now gives the requested 120
3116 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003124
Georg Brandlba83f822010-03-14 09:50:54 +00003125- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3126 decimal string that's guaranteed to round back to x under correct rounding
3127 (with round-half-to-even rounding mode). Previously it gave a string based on
3128 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3129 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3130 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003131
Georg Brandlba83f822010-03-14 09:50:54 +00003132- Issue #7117: On almost all platforms: float-to-string and string-to-float
3133 conversions within Python are now correctly rounded. Places these conversions
3134 occur include: str for floats and complex numbers; the float and complex
3135 constructors; old-style and new-style numeric formatting; serialization and
3136 deserialization of floats and complex numbers using marshal, pickle and json;
3137 parsing of float and imaginary literals in Python code; Decimal-to-float
3138 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003139
Georg Brandlba83f822010-03-14 09:50:54 +00003140 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3141 providing correctly-rounded strtod and dtoa C functions. This code is
3142 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3143 the C compiler. There may be a small number of platforms on which correct
3144 operation of this code cannot be guaranteed, so the code is not used: notably,
3145 this applies to platforms where the C double format is not IEEE 754 binary64,
3146 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3147 and Python's configure script is unable to determine how to change the FPU
3148 precision. On these platforms conversions use the platform strtod and dtoa,
3149 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003150
Georg Brandlba83f822010-03-14 09:50:54 +00003151- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3152 uses the correctly-rounded string <-> float conversions described above (when
3153 available), and so produces correctly rounded results that will display nicely
3154 under the float repr. There are two related small changes: (1) round now
3155 accepts any class with an ``__index__()`` method for its second argument (but
3156 no longer accepts floats for the second argument), and (2) an excessively
3157 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3158 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003305- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3306 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3307 but with at least one decimal point and with a default precision
3308 of 12. Previously, the behavior the same but with a default precision of 6.
3309 This more closely matches ``str()``, and reduces surprises when adding
3310 alignment flags to the empty presentation type. This also affects the new
3311 complex.__format__ in the same way.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00003459- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
3460 file with `str' filename on Windows.
3461
Antoine Pitrouaa687902009-01-01 14:11:22 +00003462- Issue #3680: Reference cycles created through a dict, set or deque iterator
3463 did not get collected.
3464
Georg Brandlba83f822010-03-14 09:50:54 +00003465- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
3466 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00003467
Benjamin Peterson7af65562008-12-29 17:56:58 +00003468- Issue #4764: With io.open, IOError.filename is set when trying to open a
3469 directory on POSIX systems.
3470
Benjamin Petersonfe231b02008-12-29 17:47:42 +00003471- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
3472 systems.
3473
Georg Brandl6425a2f2008-12-28 11:54:53 +00003474- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003475 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003476
Skip Montanarof205c132008-12-23 03:30:15 +00003477- Added test case to ensure attempts to read from a file opened for writing
3478 fail.
3479
Georg Brandlba83f822010-03-14 09:50:54 +00003480- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
3481 elapsed times, not only when some objects are uncollectable/unreachable.
3482 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00003483

Georg Brandlba83f822010-03-14 09:50:54 +00003494- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3495 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3496 instances. On a typical machine this saves 3 bytes of memory (on average) per
3497 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003498
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003499- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3500 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3501 instead of throwing a MemoryError.
3502
Georg Brandlba83f822010-03-14 09:50:54 +00003503- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3504 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003505
Benjamin Petersonc078f922008-11-21 22:27:24 +00003506- Issue #4367: Python would segfault during compiling when the unicodedata
3507 module couldn't be imported and \N escapes were present.
3508
Georg Brandlba83f822010-03-14 09:50:54 +00003509- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3510 file objects with closefd=False. The file descriptor is still kept open but
3511 the file object behaves like a closed file. The ``FileIO`` object also got a
3512 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003513
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003514- Issue #4348: Some bytearray methods returned that didn't cause any change to
3515 the bytearray, returned the same bytearray instead of a copy.
3516
Georg Brandlba83f822010-03-14 09:50:54 +00003517- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00003519- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3520
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003521- Issue #4048: The parser module now correctly validates relative imports.
3522
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003523- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3524 exec statement.
3525
Georg Brandlba83f822010-03-14 09:50:54 +00003526- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3527 does not return iterators for the 4th and 5th items.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00003529- Issue #4209: Enabling unicode_literals and the print_function in the same
3530 __future__ import didn't work.
3531
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003532- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003533 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003534
Georg Brandlba83f822010-03-14 09:50:54 +00003535- On windows, ``os.chdir()`` given unicode was not working if
3536 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3537 this code path is really executed because I cannot move to such directory on
3538 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003539
Georg Brandlba83f822010-03-14 09:50:54 +00003540- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3541 element is temporarily replaced with an equivalent frozenset. But the
3542 eventual KeyError would always report the empty ``frozenset()`` as the missing
3543 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003544
Georg Brandlba83f822010-03-14 09:50:54 +00003545- Issue #4509: Various issues surrounding resize of bytearray objects to which
3546 there are buffer exports.

3553
Georg Brandlba83f822010-03-14 09:50:54 +00003554- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Klose91a3b9e2009-04-05 21:19:13 +00003557- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3558 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003559
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003560- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3561 returned them on 64bit platforms.
3562
Walter Dörwalded960ac2009-05-03 22:36:33 +00003563- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3564 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3565 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3566 of using the replace error handler in PyUnicode_DecodeUTF8().
3567
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003568- Issue #3739: The unicode-internal encoder now reports the number of characters
3569 consumed like any other encoder (instead of the number of bytes).
3570
Georg Brandlba83f822010-03-14 09:50:54 +00003571- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3572 allocator will be automatically disabled when running under Valgrind. This
3573 gives improved memory leak detection when running under Valgrind, while taking
3574 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004818 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4819 the tests if DISPLAY is defined but can't be used.

4823
Georg Brandlba83f822010-03-14 09:50:54 +00004824- Issue #5354: New test support function import_fresh_module() makes it easy to
4825 import both normal and optimised versions of modules. test_heapq and
4826 test_warnings have been adjusted to use it, tests for other modules with both
4827 C and Python implementations in the stdlib can be adjusted to use it over
4828 time.

4838 support, which does the conversion.

4940
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004941- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4942 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4943 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4944 ``printf`` function, whereas PyString_FromFormat has an independent
4945 implementation and uses "%zd" on all platforms for size_t values.
4946 This makes a difference on win64, where ``printf`` needs "%Id" to display
4947 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004949- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4953 object; previously an int would be returned for small values. the __long__
4954 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004964 was correctly parsed but parsing of subsequent arguments failed.
4965
Vinay Sajip35e3b032008-09-01 14:33:59 +00004966- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004967 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4968 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4969 when given a tuple of classes as second argument, were looking up
4970 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4971 type object.
4972

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005110What's New in Python 2.6 beta 3?
5111================================
5112
Barry Warsaw07a4a382008-08-21 01:15:08 +00005113*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005114
5115Core and Builtins
5116-----------------
5117
Guido van Rossumf8402962008-08-20 15:01:50 +00005118- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5119 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5120 extensions do not automatically benefit from the class attribute
5121 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5122 to their tp_flags field if they care. This is a backwards
5123 compatibility feature; in 3.0, all types will use the cache by
5124 default.
5125
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005126- Keyword arguments can now follow starred arguments. (``f(a, *args,
5127 keyword=23)`` is now valid syntax.)
5128
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005129- ctypes function pointers that are COM methods have a boolean True
5130 value again.
5131
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005132- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5133 by denying s# to parse objects that have a releasebuffer procedure,
5134 and introducing s*.
5135
Georg Brandl1e13ea92008-08-11 09:07:59 +00005136- Issue #3537: Fix an assertion failure when an empty but presized dict
5137 object was stored in the freelist.
5138
Mark Dickinsonb6467572008-08-04 21:30:09 +00005139- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5140 ValueError consistently across platforms.
5141
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005142- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5143 (64bit Unix, for example), unichr() would truncate its argument and return
5144 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5145
Neal Norwitze7d8be82008-07-31 17:17:14 +00005146- Apply security patches from Apple.
5147
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005148- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5149 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5150
Antoine Pitrou92f82162008-07-25 22:22:08 +00005151- Issue #1819: function calls with several named parameters are now on
5152 average 35% faster (as measured by pybench).
5153
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005154- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5155 the python debugger steps into a class statement: the free variables (local
5156 variables defined in an outer scope) would be deleted from the outer scope.
5157
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005158- Issue #2620: Overflow checking when allocating or reallocating memory
5159 was not always being done properly in some python types and extension
5160 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5161 all been updated to perform better checks and places in the code that
5162 would previously leak memory on the error path when such an allocation
5163 failed have been fixed.
5164
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005165Library
5166-------
5167
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005168- Issue #3612: Added some missing basic types in ctypes.wintypes.
5169
Benjamin Petersone977ad42008-08-20 01:42:01 +00005170- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5171 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5172
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005173- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5174 version reported by these tools does not necessarily follow the python
5175 version numbering scheme, so the module is less strict when parsing it.
5176
Nick Coghlanf70385a2008-08-18 12:42:46 +00005177- Issue #2235: Added Py3k warnings for types which will become unhashable
5178 under the stricter __hash__ inheritance rules in 3.0. Several types
5179 which did not meet the rules for hash invariants and were already
5180 unhashable in 3.0 have now been explicitly flagged as unhashable in
5181 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5182 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5183
Brett Cannon88f801d2008-08-18 00:46:22 +00005184- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5185 imported into the module but exposed as part of the module's API.
5186
Brett Cannon7b96f072008-08-18 00:41:11 +00005187- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5188
Brett Cannon46225e72008-08-18 00:36:52 +00005189- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5190
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005191- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5192
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005193- Issue #3575: Incremental decoder's decode function now takes bytearray
5194 by using 's*' instead of 't#'.
5195
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005196- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005197 fails unicode conversion on 2nd parameter. (windows only)
5198
Georg Brandl222e2082010-08-01 22:27:39 +00005199- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005200 in a redirect.
5201
Brett Cannonabe423e2008-08-16 21:47:07 +00005202- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005203 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005204
Facundo Batistaeb90b782008-08-16 14:44:07 +00005205- Issue #2776: fixed small issue when handling an URL with double slash
5206 after a 302 response in the case of not going through a proxy.
5207
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005208- Issue #2676: in the email package, content-type parsing was hanging on
5209 pathological input because of quadratic or exponential behaviour of a
5210 regular expression.
5211
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005212- Issue #3476: binary buffered reading through the new "io" library is now
5213 thread-safe.
5214
Brett Cannonbf3157b2008-08-14 05:00:03 +00005215- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5216 since mimetools itself is deprecated. Because modules are cached, all
5217 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5218
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005219- Issue #3134: shutil referenced undefined WindowsError symbol.
5220
Robert Schuppenies14646332008-08-10 11:01:53 +00005221- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5222 menu entries were not deleted.
5223
Brett Cannon83e81842008-08-09 23:30:55 +00005224- Copied the implementation of reduce() to _functools.reduce() to have a
5225 version that did not raise a DeprecationWarning under -3.
5226
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005227- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5228 a MemoryError rather than silently stop the iteration.
5229
Guido van Rossum59ce9012008-08-09 14:55:34 +00005230- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5231 to _sre.compile() will now be rejected. This should not affect anybody
5232 since the re.compile() function never generates invalid re-bytecode.
5233
Skip Montanaroa032bf42008-08-08 22:52:51 +00005234- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5235 upon first access it can be automatically initialized from the csv file if
5236 it wasn't initialized during instantiation.
5237
Brett Cannon3aa2a492008-08-06 22:28:09 +00005238- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5239 the reload() built-in has been removed.
5240
Brett Cannon7e30b672008-08-04 21:52:25 +00005241- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005242 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005243 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
5244 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
5245 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5246 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5247 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005248
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005249- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5250 raised an AttributeError.
5251
Benjamin Peterson01a24322008-07-28 23:35:27 +00005252- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005253 asking for a specific length. This problem only affected files opened
5254 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005255
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005256- Issue #3449: Update decimal module to use most recent specification
5257 (v. 1.68) and tests (v. 2.58) from IBM.
5258
Georg Brandl222e2082010-08-01 22:27:39 +00005259- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005260

Raymond Hettinger8c664e82008-07-25 18:43:33 +00005262 on a closed shelf.
5263
Georg Brandlf9efabb2008-07-23 15:16:45 +00005264- Deprecate the "ast" parser function aliases.
5265
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005266- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5267
5268- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5269 invalid arguments.
5270
5271- Issue #3302: Fix several crashes when calling locale's gettext functions
5272 with None arguments.
5273
5274- Issue #3389: Allow resolving dotted names for handlers in logging
5275 configuration files.
5276
5277- Deprecate the sunaudio module for removal in Python 3.0.
5278
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005279- Issue #3394: zipfile.writestr sets external attributes when passed a
5280 file name rather than a ZipInfo instance, so files are extracted with
5281 mode 0600 rather than 000 under Unix.
5282
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005283- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5284 argument in python 2.5, this broke code that subclassed Popen to include its
5285 own poll method. Fixed my moving _deadstate to an _internal_poll method.
5286
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00005287Build
5288-----

5293-------------
5294
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005295- Issue #2235: the C API function PyObject_HashNotImplemented and its
5296 interaction with the tp_hash slot (added in 2.6b2) are now documented
5297
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005298- Issue #643841: The language reference now provides more detailed
5299 coverage of the lookup process for special methods. The disclaimers
5300 regarding lack of coverage of new-style classes have also been
5301 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005304What's New in Python 2.6 beta 2?
5305================================
5306
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005307*Release date: 17-Jul-2008*
5308
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005309Core and Builtins
5310-----------------
5311
Georg Brandl3e483f62008-07-16 22:57:41 +00005312- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5313 its methods now allow for items objects that can be converted to
5314 an integer using operator.index().
5315
Mark Dickinson64b7e502008-07-16 09:40:03 +00005316- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5317 produced a ValueError instead of giving the correct float.
5318
Eric Smitha5fa5a22008-07-16 00:11:49 +00005319- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5320 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5321
Mark Dickinson7103aa42008-07-15 19:08:33 +00005322- Issue #3008: the float type has a new instance method 'float.hex'
5323 and a new class method 'float.fromhex' to convert floating-point
5324 numbers to and from hexadecimal strings, respectively.
5325
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005326- Issue #2235: __hash__ is once again inherited by default. To allow
5327 collections.Hashable to remain meaningful in the presence of the
5328 default hash implementation (object.__hash__), it is now possible
5329 to explicit block inheritance of hash by setting __hash__=None at
5330 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5331 level.
5332
Nick Coghlanb028f502008-07-13 14:52:36 +00005333- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5334 the parent module cannot be found while performing an absolute import.
5335 This means that an incorrectly defined __package__ attribute will
5336 now only prevent relative imports in that module rather than causing
5337 all imports from that module to fail.
5338
Nick Coghlan14ff9942008-07-08 14:21:42 +00005339- Issue #2517: Allow unicode messages in Exceptions again by correctly
5340 bypassing the instance dictionary when looking up __unicode__ on
5341 new-style classes.
5342
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005343- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5344 set to a custom object whose write() method happens to install
5345 another file in sys.stdout.
5346
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005347- Issue #3088: Corrected a race condition in classes derived from
5348 threading.local: the first member set by a thread could be saved in
5349 another thread's dictionary.
5350
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005351- Issue #3004: Minor change to slice.indices(): the start and stop
5352 arguments are now treated identically, making the behaviour easier
5353 to describe and understand. For example, slice(None, -10,
5354 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5355 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5356 10, -1).
5357
Georg Brandl278fc502008-07-19 12:46:12 +00005358- Issue #3219: Calling a function with repeated keyword arguments,
5359 f(a=2, a=23), would not cause a syntax error. This was a regression
5360 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005361
Georg Brandl278fc502008-07-19 12:46:12 +00005362- Issue #2862: Make int and float freelist management consistent with
5363 other freelists. Changes their CompactFreeList apis into
5364 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005365

5367-------
5368
Thomas Heller57adf222008-08-14 19:10:48 +00005369- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5370 api functions without holding the GIL, which could lead to a fatal
5371 error when they failed.
5372
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005373- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005381- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5382 ForkingPickler.register() to resolve conflict with ctypes.
5383
Vinay Sajip51e65192008-07-18 09:01:10 +00005384- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

5387 a valid dlerror() message.
5388
Thomas Heller2bad6572008-07-15 17:19:50 +00005389- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5390 incomplete structure was created.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00005394- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
5395

5807
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005808- On MacOS X it is now possible to install the framework in 64-bit
5809 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005810 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005811
5812 This is controlled by the configure argument ``--with-universal-archs``:
5813
5814 - ``--with-universal-archs=all``: install 4-way universal
5815
5816 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5817
5818 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5819
5820 This option should be used in combination with ``--enable-universalsdk=``.
5821
5822 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 +00005858- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
5859 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005860
Christian Heimese74c8f22008-04-19 02:23:57 +00005861- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5862
Georg Brandl3ee81df2008-05-17 18:14:43 +00005863- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
5864 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00005865
Georg Brandl3ee81df2008-05-17 18:14:43 +00005866- Four new methods were added to the math and cmath modules: acosh,

5870 when passed a value less than or equal to zero.
Gregory P. Smith671c5d92008-04-09 18:18:43 +00005871
Georg Brandl3ee81df2008-05-17 18:14:43 +00005872- Issue #1631171: Re-implement the 'warnings' module in C (the
5873 original Python code has been kept as backup). This will allow for
5874 using the 'warning's machinery in such places as the parser where
5875 use of pure Python code is not possible. Both the ``showarning()``
5876 and ``formatwarning()`` gain an optional 'line' argument which is
5877 not called by default for backwards-compatibility reasons. Setting
5878 ``warnings.showwarning()`` to an implementation that lacks support
5879 for the ``line`` argument will raise a DeprecationWarning.

Thomas Hellerbf027c42008-04-24 18:14:19 +00005902 reference to themselves.
5903
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005904- The getpass module has been improved on Unix. It now uses /dev/tty
5905 by default and uses stderr instead of stdout. A GetPassWarning is
5906 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00005907

5918 implementation detail of the public ``types`` module, has been
5919 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00005920
Georg Brandl3ee81df2008-05-17 18:14:43 +00005921- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005922 extension modules between 32 and 64 bit platforms. See the distutls
5923 build documentation for more information.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005942- Issue #2550: The approach used by client/server code for obtaining
5943 ports to listen on in network-oriented tests has been refined in an
5944 effort to facilitate running multiple instances of the entire
5945 regression test suite in parallel without issue.
5946 test_support.bind_port() has been fixed such that it will always
5947 return a unique port -- which wasn't always the case with the
5948 previous implementation, especially if socket options had been set
5949 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5950 new implementation of bind_port() will actually raise an exception
5951 if it is passed an AF_INET/SOCK_STREAM socket with either the
5952 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5953 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5954 the socket it's been passed. This currently only applies to
5955 Windows. This option prevents any other sockets from binding to the
5956 host/port we've bound to, thus removing the possibility of the
5957 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5958 when a second SOCK_STREAM socket binds and accepts to a host/port
5959 that's already been bound by another socket. The optional preferred
5960 port parameter to bind_port() has been removed. Under no
5961 circumstances should tests be hard coding ports!
5962
5963 test_support.find_unused_port() has also been introduced, which will
5964 pass a temporary socket object to bind_port() in order to obtain an
5965 unused port. The temporary socket object is then closed and
5966 deleted, and the port is returned. This method should only be used
5967 for obtaining an unused port in order to pass to an external program
5968 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5969 a parameter to a server-oriented class that doesn't give you direct
5970 access to the underlying socket used.
5971
5972 Finally, test_support.HOST has been introduced, which should be used
5973 for the host argument of any relevant socket calls (i.e. bind and
5974 connect).

Fred Drakea8ee94b2008-03-01 02:45:07 +00006251- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006252 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006253
Georg Brandlad61bc82008-02-23 15:11:18 +00006254- Issue #2067: file.__exit__() now calls subclasses' close() method.
6255
6256- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006257
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006258- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006259 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006260
Eric Smitha73fbe72008-02-23 03:09:44 +00006261- Added the future_builtins module, which contains hex() and oct().
6262 These are the PEP 3127 version of these functions, designed to be
6263 compatible with the hex() and oct() builtins from Python 3.0. They
6264 differ slightly in their output formats from the existing, unchanged
6265 Python 2.6 builtins. The expected usage of the future_builtins
6266 module is:
6267 from future_builtins import hex, oct
6268
Eric Smith7ef40bf2008-02-20 23:34:22 +00006269- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6270 exponents for exponents with absolute value < 100. Follows C99
6271 standard. This is a change on Windows, which would use 3 digits.
6272 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6273 so that any alterations it does to the resulting string will be
6274 available in stringlib/formatter.h (for float.__format__).
6275
Eric Smith5a3c1352008-02-19 13:21:56 +00006276- Implemented PEP 3101, Advanced String Formatting. This adds a new
6277 builtin format(); a format() method for str and unicode; a
6278 __format__() method to object, str, unicode, int, long, float, and
6279 datetime; the class string.Formatter; and the C API
6280 PyObject_Format().
6281
Georg Brandl3ee81df2008-05-17 18:14:43 +00006282- Fixed several potential crashes, all caused by specially crafted
6283 __del__ methods exploiting objects in temporarily inconsistent
6284 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006285
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006286- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006287 prevent a possible crash: an Abstract Base Class would try to access
6288 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006289
Georg Brandl3ee81df2008-05-17 18:14:43 +00006290- Fixed repr() and str() of complex numbers with infinity or nan as
6291 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006292
Georg Brandl3ee81df2008-05-17 18:14:43 +00006293- Clear all free lists during a gc.collect() of the highest generation
6294 in order to allow pymalloc to free more arenas. Python may give back
6295 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006296
Georg Brandl3ee81df2008-05-17 18:14:43 +00006297- Issue #2045: Fix an infinite recursion triggered when printing a
6298 subclass of collections.defaultdict, if its default_factory is set
6299 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006300
Christian Heimesf75dbef2008-02-08 00:11:31 +00006301- Fixed a minor memory leak in dictobject.c. The content of the free
6302 list was not freed on interpreter shutdown.
6303
Georg Brandl21e99f42010-03-07 15:23:59 +00006304- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006305 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006306
Georg Brandl3ee81df2008-05-17 18:14:43 +00006307- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6308 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006309 to compact the internal free lists of pre-allocted ints and floats.
6310
Georg Brandl3ee81df2008-05-17 18:14:43 +00006311- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6312 calls. Python expected the return type int but the fork familie
6313 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006314
Georg Brandl3ee81df2008-05-17 18:14:43 +00006315- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6316 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006317
Georg Brandl3ee81df2008-05-17 18:14:43 +00006318- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6319 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006320

6322 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006323
Georg Brandl3ee81df2008-05-17 18:14:43 +00006324- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6325 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006326
Georg Brandl3ee81df2008-05-17 18:14:43 +00006327- Patch #1473257: generator objects gain a gi_code attribute. This is
6328 the same object as the func_code attribute of the function that
6329 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006330
Georg Brandl3ee81df2008-05-17 18:14:43 +00006331- Issue #1920: "while 0" statements were completely removed by the
6332 compiler, even in the presence of an "else" clause, which is
6333 supposed to be run when the condition is false. Now the compiler
6334 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006335
Guido van Rossumeead05f2008-01-24 18:21:02 +00006336- A few crashers fixed: weakref_in_del.py (issue #1377858);
6337 loosing_dict_ref.py (issue #1303614, test67.py);
6338 borrowed_ref_[34].py (not in tracker).
6339
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006340- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006341 suppressed while an extension is loaded by calling SetErrorMode in
6342 dynload_win.c. The error is still reported properly.
6343
Georg Brandl3ee81df2008-05-17 18:14:43 +00006344- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006345 several extension methods and modules do not work without unicode
6346 support.
6347
Georg Brandl26543b12008-01-21 18:36:51 +00006348- Issue #1882: when compiling code from a string, encoding cookies in the
6349 second line of code were not always recognized correctly.
6350
Georg Brandl14404b62008-01-19 19:27:05 +00006351- Issue #1679: "0x" was taken as a valid integer literal.
6352
Georg Brandl6caad7d2008-01-26 14:19:22 +00006353- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006354 added.
6355
Christian Heimesc94e2b52008-01-14 04:13:37 +00006356- sys.float_info / PyFloat_GetInfo: The floating point information
6357 object was converted from a dict to a specialized structseq object.
6358
Georg Brandl3ee81df2008-05-17 18:14:43 +00006359- Patch #1816: Added sys.flags structseq. It exposes the status of
6360 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006361
Georg Brandl3ee81df2008-05-17 18:14:43 +00006362- Objects/structseq.c: Implemented new structseq representation. The
6363 patch makes structseqs (e.g. the return value of os.stat) more
6364 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006365
Georg Brandl3ee81df2008-05-17 18:14:43 +00006366- Patch #1700288: added a type attribute cache that caches method
6367 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006368
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006369- Bug #1776: __import__() no longer accepts filenames on any platform.

6373
Georg Brandl3ee81df2008-05-17 18:14:43 +00006374- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6375 envvar and sys.dont_write_bytecode attribute. All these can be set
6376 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006377
Georg Brandl3ee81df2008-05-17 18:14:43 +00006378- Improve some exception messages when Windows fails to load an
6379 extension module. Now we get for example '%1 is not a valid Win32
6380 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006381
Georg Brandl3ee81df2008-05-17 18:14:43 +00006382- Bug #1481296: Fixed long(float('nan')) != 0L.

6385 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006386
Christian Heimes0a8143f2007-12-18 23:22:54 +00006387- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006388 and INF. float("nan"), float("inf") and float("-inf") now work on
6389 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006390
Georg Brandl3ee81df2008-05-17 18:14:43 +00006391- Compiler now generates simpler and faster code for dictionary
6392 literals. The oparg for BUILD_MAP now indicates an estimated
6393 dictionary size. There is a new opcode, STORE_MAP, for adding
6394 entries to the dictionary.

6426 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006427
Georg Brandl3ee81df2008-05-17 18:14:43 +00006428- Issue #1265: Fix a problem with sys.settrace, if the tracing
6429 function uses a generator expression when at the same time the
6430 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006431
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006432- sets and frozensets now have an isdisjoint() method.
6433

6437
Georg Brandl21e99f42010-03-07 15:23:59 +00006438- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006439 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6440 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006441
Georg Brandl3ee81df2008-05-17 18:14:43 +00006442- Issue #1686386: Tuple's tp_repr did not take into account the
6443 possibility of having a self-referential tuple, which is possible
6444 from C code. Nor did object's tp_str consider that a type's tp_str
6445 could do something that could lead to an inifinite recursion.
6446 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6447 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006448
Georg Brandl3ee81df2008-05-17 18:14:43 +00006449- Issue #1164: It was possible to trigger deadlock when using the
6450 'print' statement to write to a file since the GIL was not released
6451 as needed. Now PyObject_Print() does the right thing along with
6452 various tp_print implementations of the built-in types and those in
6453 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006455- Issue #1147: Exceptions were directly allowing string exceptions in
6456 their throw() method even though string exceptions no longer
6457 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006459- Issue #1096: Prevent a segfault from getting the repr of a very
6460 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006461
Brett Cannon1e534b52007-09-07 04:18:30 +00006462- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006463 PyObject_Call() never calling back out to Python code to trigger
6464 recursion depth updates/checks. Required the creation of a static
6465 RuntimeError instance in case normalizing an exception put the
6466 recursion check value past its limit. Fixes crashers
6467 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006482- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006483 __*__ attributes. (Some already existed, e.g., __doc__ and
6484 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006485
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006486- Add -3 option to the interpreter to warn about features that are

6490 calls.
6491
Collin Winter62903052007-05-18 23:11:24 +00006492- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006493 "except E as target:". This is to provide forwards compatibility
6494 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006495
Brett Cannon229cee22007-05-05 01:34:02 +00006496- Deprecate BaseException.message as per PEP 352.
6497
Georg Brandl3ee81df2008-05-17 18:14:43 +00006498- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00006501- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006502 setting a plain string, ie don't expand to single letter identifiers.
6503
Raymond Hettinger13936692007-04-11 18:40:58 +00006504- Request #1191699: Slices can now be pickled.
6505
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006506- Request #1193128: str.translate() now allows a None argument for
6507 translations that only remove characters without re-mapping the
6508 remaining characters.
6509
Georg Brandl5cb76c12007-03-21 09:00:39 +00006510- Patch #1682205: a TypeError while unpacking an iterable is no longer

6512
Neal Norwitzaa754b72007-03-21 06:39:48 +00006513- Remove unused file Python/fmod.c.
6514
Guido van Rossum143b5642007-03-23 04:58:42 +00006515- Bug #1683368: The object.__init__() and object.__new__() methods are
6516 now stricter in rejecting excess arguments. The only time when
6517 either allows excess arguments is when it is not overridden and the
6518 other one is. For backwards compatibility, when both are
6519 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006520 warning later). Also, type.__init__() insists on the same signature
6521 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006522
Georg Brandl3ee81df2008-05-17 18:14:43 +00006523- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6524 object to complex using its __complex__() method before falling back
6525 to the __float__() method. Therefore, the functions in the cmath
6526 module now can operate on objects that define a __complex__()
6527 method.

6538 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006545- Bug #1678647: write a newline after printing an exception in any
6546 case, even when converting the value to a string failed.
6547
Georg Brandl871f1bc2007-03-12 13:17:36 +00006548- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006549 its argument, if it exists. If not, it will work like before. This
6550 allows customizing the output of dir() in the presence of a
6551 __getattr__().

6560 parthensized forms. This means complex(repr(x)) now works instead of
6561 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006562
Georg Brandlaa2321b2007-03-07 00:40:28 +00006563- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006564 makes the filenames the warning module prints much more sensible
6565 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006578- Patch #1674228: when assigning a slice (old-style), check for the
6579 sq_ass_slice instead of the sq_slice slot.
6580
Georg Brandl3ee81df2008-05-17 18:14:43 +00006581- When printing an unraisable error, don't print exceptions. before

7192 Python would crash instead of raising an error.
7193

7210 incompatibility since it never made sense with ordinary subclasses
7211 -- the failure just occurred later, with a more cumbersome
7212 exception.

7496 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007497
Georg Brandl3ee81df2008-05-17 18:14:43 +00007498- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007499 that the SMTP.starttls() caller no longer needs to call ehlo()
7500 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007501 does not claim to support starttls. Adds the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007601 time so that opening a database previously created with the DB_DUP
7602 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7603 opens. Specifically: dictionary assignment to a DB object will
7604 replace all values for a given key when the database allows
7605 duplicate values. DB users should use DB.put(k, v) when they want
7606 to store duplicates; not DB[k] = v.

7613 characters with ASCII value less than 32. Also, it correctly quotes
7614 dots only if they occur on a single line, as opposed to the previous
7615 behavior of quoting dots if they are the second character of any
7616 line.

7939-----
7940
Georg Brandl3ee81df2008-05-17 18:14:43 +00007941- Unified naming convention for free lists and their limits. All free
7942 lists in Object/ are named ``free_list``, the counter ``numfree``
7943 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7944 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007945
Georg Brandl3ee81df2008-05-17 18:14:43 +00007946- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7947 to ``PyTuple_SetItem``, it can be used to populate a brand new
7948 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007949
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007950- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007952- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7953 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7954 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007955
7956- Patch #1720595: add T_BOOL to the range of structmember types.
7957
7958- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7959 ``PyFloat_GetInfo()`` to the float API.
7960
Georg Brandl3ee81df2008-05-17 18:14:43 +00007961- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7962 of w# format code incorrectly truncated the length to an int, even
7963 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7964 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007965
Georg Brandl3ee81df2008-05-17 18:14:43 +00007966- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7967 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007968
Georg Brandl3ee81df2008-05-17 18:14:43 +00007969- PEP 3123: Provide forward compatibility with Python 3.0, while
7970 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7971 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007972
Georg Brandl3ee81df2008-05-17 18:14:43 +00007973- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7974 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007975
7976- Patch #1733960: Allow T_LONGLONG to accept ints.
7977
7978- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7979

7983
7984- Fix some leftovers from the conversion from int to Py_ssize_t
7985 (relevant to strings and sequences of more than 2**31 items).
7986
7987- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7988 outside of pystate.c and should not be necessary.
7989
Georg Brandl3ee81df2008-05-17 18:14:43 +00007990- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7991 absolute imports. In earlier versions they might have used relative
7992 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007993
Georg Brandl3ee81df2008-05-17 18:14:43 +00007994- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7995 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007996
Georg Brandl3ee81df2008-05-17 18:14:43 +00007997- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7998 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008004- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8005 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8006 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8007 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008008
Georg Brandl3ee81df2008-05-17 18:14:43 +00008009- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00008020- buildtools now raises a DeprecationWarning.
8021
Georg Brandl3ee81df2008-05-17 18:14:43 +00008022- Removed the macfs module. It had been deprecated since Python 2.5.
8023 This lead to the deprecation of macostools.touched() as it relied
8024 solely on macfs and was a no-op under OS X.
