Ned Deily18fae3f2013-01-31 01:24:55 -08001481- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1482 In particular, fix extension module build failures when trying to use
1483 32-bit-only installer Pythons on systems with Xcode 4 (currently
1484 OS X 10.8, 10.7, and optionally 10.6).
1485 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1486 * Since Xcode 4 removes ppc support, extension module builds now
1487 check for ppc compiler support and by default remove ppc and
1488 ppc64 archs when they are not available.
1489 * Extension module builds now revert to using system installed
1490 headers and libs (/usr and /System/Library) if the SDK used
1491 to build the interpreter is not installed or has moved.
1492 * Try to avoid building extension modules with deprecated
1493 and problematic Apple llvm-gcc compiler. If original compiler
1494 is not available, use clang instead by default.

1846 int.__pow__. These overflow checks were causing int.__pow__ to produce
1847 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001848 compiler optimizing the check away. Also fix similar overflow checks
1849 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01001919 has left two versions of customize_compiler, the original in
1920 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001925- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1926 Distutils-based packages with C extension modules may fail because
1927 Apple has removed gcc-4.2, the version used to build python.org
1928 64-bit/32-bit Pythons. If the user does not explicitly override
1929 the default C compiler by setting the CC environment variable,
1930 Distutils will now attempt to compile extension modules with clang
1931 if gcc-4.2 is required but not found. Also as a convenience, if
1932 the user does explicitly set CC, substitute its value as the default
1933 compiler in the Distutils LDSHARED configuration variable for OS X.
1934 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1935 SDK, neither of which are available in Xcode 4. This change does not
1936 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002186- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2187 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2188 interpreter process. This could cause failures in non-Distutils subprocesses
2189 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002190 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002191 deployment target only in the environment of each build subprocess. It is
2192 still possible to globally override the default by setting
2193 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2194 greater or equal to the default value, the value with which the interpreter
2195 was built.

2224 updating the check interval, so if the user decreases the check interval,
2225 the ticker doesn't have to wind down to zero from the old starting point
2226 before the new interval takes effect. And if the user increases the
2227 interval, it makes sure the new limit takes effect right away rather have an
2228 early task switch before recognizing the new interval.

Raymond Hettinger74f869e2010-09-13 22:14:36 +00003200- Issue #9826: OrderedDict.__repr__ can now handle self-referential
3201 values: d['x'] = d.
3202
Victor Stinner8fc843b2010-09-17 23:35:50 +00003203- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.

Antoine Pitroue4195e82010-09-12 14:56:27 +00003205- Issue #9837: The read() method of ZipExtFile objects (as returned by
3206 ZipFile.open()) could return more bytes than requested.
3207
Raymond Hettinger20397532010-09-12 02:11:45 +00003208- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3209 This prevents user-created self-referencing ordered dictionaries from
3210 becoming permanently uncollectable GC garbage. The downside is that
3211 removing __del__ means that the internal doubly-linked list has to wait for
3212 GC collection rather than freeing memory immediately when the refcnt drops
3213 to zero.
3214
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003215- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00003216 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003217 value.
3218
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003219- Issue #9792: In case of connection failure, socket.create_connection()
3220 would swallow the exception and raise a new one, making it impossible
3221 to fetch the original errno, or to filter timeout errors. Now the
3222 original error is re-raised.
3223
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003224- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3225 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3226 be updated back after the system call. Original patch by Brian Brazil.
3227
Antoine Pitroudca9de92010-09-04 17:52:26 +00003228- Issue #1100562: Fix deep-copying of objects derived from the list and

3232 ConfigParser.write.
3233
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003234- Issue #808164: Fixed socket.close to avoid references to globals, to
3235 avoid issues when socket.close is called from a __del__ method.
3236
Terry Reedyd2d2ae92010-11-11 23:22:19 +00003237- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
3238 can be set to False to turn off the previously undocumented 'popularity'
3239 heuristic. Patch by Terry Reedy and Eli Bendersky
3240
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003241- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3242 falling into recursion.
3243
R. David Murray7c4bf552010-08-25 01:45:57 +00003244- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3245 character years even if the message contains RFC822 two character years.
3246
Daniel Stutzbach91287322010-08-24 21:09:30 +00003247- Issue #8750: Fixed MutableSet's methods to correctly handle

3259 module now correctly return a set. (Patch by Eli Bendersky.)
3260
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003261- Issue #9617: Signals received during a low-level write operation aren't
3262 ignored by the buffered IO layer anymore.
3263
Benjamin Peterson52c36052010-08-21 03:03:22 +00003264- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3265 are not held onto after they are deleted elsewhere.
3266
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003267- Issue #9626: the view methods for collections.OrderedDict() were returning
3268 the unordered versions inherited from dict. Those methods are now
3269 overridden to provide ordered views.
3270
Éric Araujo0389ae62010-08-14 03:07:46 +00003271- Issue #8688: MANIFEST files created by distutils now include a magic
3272 comment indicating they are generated. Manually maintained MANIFESTs
3273 without this marker will not be overwritten or removed.
3274
Antoine Pitroue1436d12010-08-12 15:25:51 +00003275- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3276 and a BadZipfile error is raised if it doesn't match (as used to be the
3277 case in Python 2.5 and earlier).
3278
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003279- Issue #9550: a BufferedReader could issue an additional read when the
3280 original read request had been satisfied, which could block indefinitely
3281 when the underlying raw IO channel was e.g. a socket. Report and original
3282 patch by Jason V. Miller.
3283
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003284- Issue #9551: Don't raise TypeError when setting the value to None for
3285 SafeConfigParser instances constructed with allow_no_value == True.

Senthil Kumarane677ecf2010-08-08 11:56:31 +00003302- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
3303 This is how it is supposed to work, wget and curl do the same. Previous
3304 behavior was wrong.

3312 the option character for the added 'h/help' option if prefix_chars
3313 does not contain a '-', instead of raising an error.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003671- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3672 start byte and the continuation byte(s) are now considered invalid, instead
3673 of the number of bytes specified by the start byte.
3674 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3675 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3676 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3686 objects. (1) The comparison could incorrectly return True in some cases
3687 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3688 (2) The comparison raised an OverflowError for large integers, leading

3830 non-float non-integer argument is now converted to an integer (if possible)
3831 using its __int__ method. Previously, only small arguments were treated this
3832 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00003883- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3884 operation raises multiple signals and more than one of those signals is
3885 trapped, the specification determines the order in which the signals should be
3886 handled. In many cases this order wasn't being followed, leading to the wrong

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004032 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4033 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4034 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4054Core and Builtins
4055-----------------
4056
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004057- Issue #7301: Add environment variable $PYTHONWARNINGS.
4058
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004059- Issue #8329: Don't return the same lists from select.select when no fds are
4060 changed.
4061
Georg Brandlfee0f442010-05-22 21:26:21 +00004062- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004063 on 64-bit machines. The shift count for either left or right shift is
4064 permitted to be up to sys.maxsize.
4065
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004066- Ensure that tokenization of identifiers is not affected by locale.
4067
Georg Brandlfee0f442010-05-22 21:26:21 +00004068- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004070- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4071
Georg Brandlfee0f442010-05-22 21:26:21 +00004072- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4073 with a non-empty format string. This is an effort to future-proof user
4074 code. If a derived class does not currently implement __format__ but later
4075 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004076 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004077 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004078
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004079- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00004092- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004093 (SIGINT). If an error occurs while importing the site module, the error is
4094 printed and Python exits. Initialize the GIL before importing the site

4109
Georg Brandlfee0f442010-05-22 21:26:21 +00004110- Issue #8257: The Decimal construct now accepts a float instance directly,
4111 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004112
4113 >>> Decimal(1.1)
4114 Decimal('1.100000000000000088817841970012523233890533447265625')
4115
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004116- collections.Counter() now supports a subtract() method.
4117
Georg Brandlfee0f442010-05-22 21:26:21 +00004118- The functools module now has a total_ordering() class decorator to simplify
4119 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004121- The functools module also adds cmp_to_key() as a tool to transition old-style
4122 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004123
Georg Brandlfee0f442010-05-22 21:26:21 +00004124- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4125 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004126
Georg Brandlfee0f442010-05-22 21:26:21 +00004127- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4128 InvalidOperation instead of returning False. (Comparisons involving a quiet
4129 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4130 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004131
Georg Brandlfee0f442010-05-22 21:26:21 +00004132- Issue #2531: Comparison operations between floats and Decimal instances now
4133 return a result based on the numeric values of the operands; previously they
4134 returned an arbitrary result based on the relative ordering of id(float) and
4135 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004136
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004137- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004138 argument `-` which tells it to read files to compile from stdin. Each line is
4139 read on demand and the named file is compiled immediately. (Original patch by
4140 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004141
Georg Brandlfee0f442010-05-22 21:26:21 +00004142- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00004145- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4146 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004147 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004148
Georg Brandlfee0f442010-05-22 21:26:21 +00004149- Comparisons using one of <, <=, >, >= between a complex instance and a
4150 Fractions instance now raise TypeError instead of returning True/False. This
4151 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4152 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004153

Georg Brandlba83f822010-03-14 09:50:54 +00004256- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4257 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4258 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004259 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4260 inconsistent: __int__ was used for some integer codes but not for others, and
4261 the set of integer codes for which it was used differed between native packing
4262 and standard packing.)

4476 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4477 Xicluna who helped with the patch.

Georg Brandlba83f822010-03-14 09:50:54 +00004570 file position when calling `truncate()`. It would previously change the file
4571 position to the given argument, which goes against the tradition of

4575 class used to represent files stored inside an archive. The new
4576 implementation is significantly faster and can be wrapped in a

4578 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4591 encoded string for them. This ensures that the upload and register commands
4592 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004862- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4863 decimal string that's guaranteed to round back to x under correct rounding
4864 (with round-half-to-even rounding mode). Previously it gave a string based on
4865 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4866 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4867 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004868
Georg Brandlba83f822010-03-14 09:50:54 +00004869- Issue #7117: On almost all platforms: float-to-string and string-to-float
4870 conversions within Python are now correctly rounded. Places these conversions
4871 occur include: str for floats and complex numbers; the float and complex
4872 constructors; old-style and new-style numeric formatting; serialization and
4873 deserialization of floats and complex numbers using marshal, pickle and json;
4874 parsing of float and imaginary literals in Python code; Decimal-to-float
4875 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004876
Georg Brandlba83f822010-03-14 09:50:54 +00004877 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4878 providing correctly-rounded strtod and dtoa C functions. This code is
4879 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4880 the C compiler. There may be a small number of platforms on which correct
4881 operation of this code cannot be guaranteed, so the code is not used: notably,
4882 this applies to platforms where the C double format is not IEEE 754 binary64,
4883 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4884 and Python's configure script is unable to determine how to change the FPU
4885 precision. On these platforms conversions use the platform strtod and dtoa,
4886 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004887
Georg Brandlba83f822010-03-14 09:50:54 +00004888- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4889 uses the correctly-rounded string <-> float conversions described above (when
4890 available), and so produces correctly rounded results that will display nicely
4891 under the float repr. There are two related small changes: (1) round now
4892 accepts any class with an ``__index__()`` method for its second argument (but
4893 no longer accepts floats for the second argument), and (2) an excessively
4894 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4895 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005042- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5043 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5044 but with at least one decimal point and with a default precision
5045 of 12. Previously, the behavior the same but with a default precision of 6.
5046 This more closely matches ``str()``, and reduces surprises when adding
5047 alignment flags to the empty presentation type. This also affects the new
5048 complex.__format__ in the same way.
5049
5050- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

5187
Georg Brandlba83f822010-03-14 09:50:54 +00005188- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5189 existing .py counterpart, override the co_filename attributes of all code
5190 objects if the original filename is obsolete (which can happen if the file has
5191 been renamed, moved, or if it is accessed through different paths). Patch by
5192 Ziga Seilnacht and Jean-Paul Calderone.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00005196- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
5197 file with `str' filename on Windows.
5198
Antoine Pitrouaa687902009-01-01 14:11:22 +00005199- Issue #3680: Reference cycles created through a dict, set or deque iterator
5200 did not get collected.
5201
Georg Brandlba83f822010-03-14 09:50:54 +00005202- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
5203 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00005204
Benjamin Peterson7af65562008-12-29 17:56:58 +00005205- Issue #4764: With io.open, IOError.filename is set when trying to open a
5206 directory on POSIX systems.
5207
Benjamin Petersonfe231b02008-12-29 17:47:42 +00005208- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
5209 systems.
5210
Georg Brandl6425a2f2008-12-28 11:54:53 +00005211- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00005212 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00005213
Skip Montanarof205c132008-12-23 03:30:15 +00005214- Added test case to ensure attempts to read from a file opened for writing
5215 fail.
5216
Georg Brandlba83f822010-03-14 09:50:54 +00005217- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
5218 elapsed times, not only when some objects are uncollectable/unreachable.
5219 Original patch by Neil Schemenauer.

Georg Brandlba83f822010-03-14 09:50:54 +00005231- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5232 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5233 instances. On a typical machine this saves 3 bytes of memory (on average) per
5234 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00005235
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005236- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
5237 interpreter to abort ("Fatal Python error: Could not reset the stack!")
5238 instead of throwing a MemoryError.
5239
Georg Brandlba83f822010-03-14 09:50:54 +00005240- Issue #3689: The list reversed iterator now supports __length_hint__ instead
5241 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00005242
Benjamin Petersonc078f922008-11-21 22:27:24 +00005243- Issue #4367: Python would segfault during compiling when the unicodedata
5244 module couldn't be imported and \N escapes were present.
5245
Georg Brandlba83f822010-03-14 09:50:54 +00005246- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5247 file objects with closefd=False. The file descriptor is still kept open but
5248 the file object behaves like a closed file. The ``FileIO`` object also got a
5249 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00005250
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005251- Issue #4348: Some bytearray methods returned that didn't cause any change to
5252 the bytearray, returned the same bytearray instead of a copy.
5253
Georg Brandlba83f822010-03-14 09:50:54 +00005254- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00005256- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
5257
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00005258- Issue #4048: The parser module now correctly validates relative imports.
5259
Benjamin Petersondcee09d2008-10-31 02:16:05 +00005260- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
5261 exec statement.
5262
Georg Brandlba83f822010-03-14 09:50:54 +00005263- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
5264 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00005265
Benjamin Petersonbdca9422008-10-26 20:21:13 +00005266- Issue #4209: Enabling unicode_literals and the print_function in the same
5267 __future__ import didn't work.
5268
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005269- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005270 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005271
Georg Brandlba83f822010-03-14 09:50:54 +00005272- On windows, ``os.chdir()`` given unicode was not working if
5273 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5274 this code path is really executed because I cannot move to such directory on
5275 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005276
Georg Brandlba83f822010-03-14 09:50:54 +00005277- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5278 element is temporarily replaced with an equivalent frozenset. But the
5279 eventual KeyError would always report the empty ``frozenset()`` as the missing
5280 key. Now it correctly refers to the initial element.

Georg Brandlba83f822010-03-14 09:50:54 +00005282- Issue #4509: Various issues surrounding resize of bytearray objects to which

5288
Gregory P. Smithae91d092009-03-02 05:13:57 +00005289- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
5290
Georg Brandlba83f822010-03-14 09:50:54 +00005291- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Klose91a3b9e2009-04-05 21:19:13 +00005294- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
5295 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00005297- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
5298 returned them on 64bit platforms.
5299
Walter Dörwalded960ac2009-05-03 22:36:33 +00005300- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5301 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5302 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5303 of using the replace error handler in PyUnicode_DecodeUTF8().
5304
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005305- Issue #3739: The unicode-internal encoder now reports the number of characters
5306 consumed like any other encoder (instead of the number of bytes).
5307
Georg Brandlba83f822010-03-14 09:50:54 +00005308- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5309 allocator will be automatically disabled when running under Valgrind. This
5310 gives improved memory leak detection when running under Valgrind, while taking
5311 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00006556- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6557 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006558 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6559 the tests if DISPLAY is defined but can't be used.

6565 import both normal and optimised versions of modules. test_heapq and
6566 test_warnings have been adjusted to use it, tests for other modules with both
6567 C and Python implementations in the stdlib can be adjusted to use it over
6568 time.

6577 should cause a test to be skipped are now done using import_module from test
6578 support, which does the conversion.

6680
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006681- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6682 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6683 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6684 ``printf`` function, whereas PyString_FromFormat has an independent
6685 implementation and uses "%zd" on all platforms for size_t values.
6686 This makes a difference on win64, where ``printf`` needs "%Id" to display
6687 64bit values.

6693 object; previously an int would be returned for small values. the __long__
6694 method is allowed to return either an int or a long, but the behaviour of
6695 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006704 was correctly parsed but parsing of subsequent arguments failed.
6705
Vinay Sajip35e3b032008-09-01 14:33:59 +00006706- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006707 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6708 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6709 when given a tuple of classes as second argument, were looking up
6710 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6711 type object.

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00006839- Issue #3833: Use a different upgrade code for Win64 installers.
6840
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00006841- Issue #2271: Set SecureCustomProperties so that installation will properly
6842 use the TARGETDIR even for unprivileged users.
6843
Martin v. Löwis67543a92008-09-08 12:02:45 +00006844- Allow passing the MSI file name to merge.py.
6845
Vinay Sajip844f7412008-09-09 13:42:08 +00006846- Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00006847 with GNU build target guidelines.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006850What's New in Python 2.6 beta 3?
6851================================
6852
Barry Warsaw07a4a382008-08-21 01:15:08 +00006853*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006854
6855Core and Builtins
6856-----------------
6857
Guido van Rossumf8402962008-08-20 15:01:50 +00006858- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6859 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6860 extensions do not automatically benefit from the class attribute
6861 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6862 to their tp_flags field if they care. This is a backwards
6863 compatibility feature; in 3.0, all types will use the cache by
6864 default.
6865
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006866- Keyword arguments can now follow starred arguments. (``f(a, *args,
6867 keyword=23)`` is now valid syntax.)
6868
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006869- ctypes function pointers that are COM methods have a boolean True
6870 value again.
6871
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006872- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6873 by denying s# to parse objects that have a releasebuffer procedure,
6874 and introducing s*.
6875
Georg Brandl1e13ea92008-08-11 09:07:59 +00006876- Issue #3537: Fix an assertion failure when an empty but presized dict
6877 object was stored in the freelist.
6878
Mark Dickinsonb6467572008-08-04 21:30:09 +00006879- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6880 ValueError consistently across platforms.
6881
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006882- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6883 (64bit Unix, for example), unichr() would truncate its argument and return
6884 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6885
Neal Norwitze7d8be82008-07-31 17:17:14 +00006886- Apply security patches from Apple.
6887
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006888- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6889 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6890
Antoine Pitrou92f82162008-07-25 22:22:08 +00006891- Issue #1819: function calls with several named parameters are now on
6892 average 35% faster (as measured by pybench).
6893
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006894- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6895 the python debugger steps into a class statement: the free variables (local
6896 variables defined in an outer scope) would be deleted from the outer scope.
6897
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006898- Issue #2620: Overflow checking when allocating or reallocating memory
6899 was not always being done properly in some python types and extension
6900 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6901 all been updated to perform better checks and places in the code that
6902 would previously leak memory on the error path when such an allocation
6903 failed have been fixed.
6904
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006905Library
6906-------
6907
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006908- Issue #3612: Added some missing basic types in ctypes.wintypes.
6909
Benjamin Petersone977ad42008-08-20 01:42:01 +00006910- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6911 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6912
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006913- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6914 version reported by these tools does not necessarily follow the python
6915 version numbering scheme, so the module is less strict when parsing it.
6916
Nick Coghlanf70385a2008-08-18 12:42:46 +00006917- Issue #2235: Added Py3k warnings for types which will become unhashable
6918 under the stricter __hash__ inheritance rules in 3.0. Several types
6919 which did not meet the rules for hash invariants and were already
6920 unhashable in 3.0 have now been explicitly flagged as unhashable in
6921 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6922 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6923
Brett Cannon88f801d2008-08-18 00:46:22 +00006924- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6925 imported into the module but exposed as part of the module's API.
6926
Brett Cannon7b96f072008-08-18 00:41:11 +00006927- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6928
Brett Cannon46225e72008-08-18 00:36:52 +00006929- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6930
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006931- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6932
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006933- Issue #3575: Incremental decoder's decode function now takes bytearray
6934 by using 's*' instead of 't#'.
6935
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006936- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006937 fails unicode conversion on 2nd parameter. (windows only)
6938
Georg Brandl222e2082010-08-01 22:27:39 +00006939- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006940 in a redirect.
6941
Brett Cannonabe423e2008-08-16 21:47:07 +00006942- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006943 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006944
Facundo Batistaeb90b782008-08-16 14:44:07 +00006945- Issue #2776: fixed small issue when handling an URL with double slash
6946 after a 302 response in the case of not going through a proxy.
6947
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006948- Issue #2676: in the email package, content-type parsing was hanging on
6949 pathological input because of quadratic or exponential behaviour of a
6950 regular expression.
6951
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006952- Issue #3476: binary buffered reading through the new "io" library is now
6953 thread-safe.
6954
Brett Cannonbf3157b2008-08-14 05:00:03 +00006955- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6956 since mimetools itself is deprecated. Because modules are cached, all
6957 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6958
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006959- Issue #3134: shutil referenced undefined WindowsError symbol.
6960
Robert Schuppenies14646332008-08-10 11:01:53 +00006961- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6962 menu entries were not deleted.
6963
Brett Cannon83e81842008-08-09 23:30:55 +00006964- Copied the implementation of reduce() to _functools.reduce() to have a
6965 version that did not raise a DeprecationWarning under -3.
6966
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006967- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6968 a MemoryError rather than silently stop the iteration.
6969
Guido van Rossum59ce9012008-08-09 14:55:34 +00006970- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6971 to _sre.compile() will now be rejected. This should not affect anybody
6972 since the re.compile() function never generates invalid re-bytecode.
6973
Skip Montanaroa032bf42008-08-08 22:52:51 +00006974- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6975 upon first access it can be automatically initialized from the csv file if
6976 it wasn't initialized during instantiation.
6977
Brett Cannon3aa2a492008-08-06 22:28:09 +00006978- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6979 the reload() built-in has been removed.
6980
Brett Cannon7e30b672008-08-04 21:52:25 +00006981- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006982 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006983 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6984 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6985 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6986 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6987 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006988
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006989- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6990 raised an AttributeError.
6991
Benjamin Peterson01a24322008-07-28 23:35:27 +00006992- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006993 asking for a specific length. This problem only affected files opened
6994 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006995
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006996- Issue #3449: Update decimal module to use most recent specification
6997 (v. 1.68) and tests (v. 2.58) from IBM.
6998
Georg Brandl222e2082010-08-01 22:27:39 +00006999- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007000

7003
Georg Brandlf9efabb2008-07-23 15:16:45 +00007004- Deprecate the "ast" parser function aliases.
7005
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007006- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7007
7008- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7009 invalid arguments.
7010
7011- Issue #3302: Fix several crashes when calling locale's gettext functions
7012 with None arguments.
7013
7014- Issue #3389: Allow resolving dotted names for handlers in logging
7015 configuration files.
7016
7017- Deprecate the sunaudio module for removal in Python 3.0.
7018
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007019- Issue #3394: zipfile.writestr sets external attributes when passed a
7020 file name rather than a ZipInfo instance, so files are extracted with
7021 mode 0600 rather than 000 under Unix.
7022
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007023- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7024 argument in python 2.5, this broke code that subclassed Popen to include its
7025 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7034
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007035- Issue #2235: the C API function PyObject_HashNotImplemented and its
7036 interaction with the tp_hash slot (added in 2.6b2) are now documented
7037
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007038- Issue #643841: The language reference now provides more detailed
7039 coverage of the lookup process for special methods. The disclaimers
7040 regarding lack of coverage of new-style classes have also been
7041 removed, since the coverage is now fairly reasonable.

7046
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007047*Release date: 17-Jul-2008*

7050-----------------
7051
Georg Brandl3e483f62008-07-16 22:57:41 +00007052- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7053 its methods now allow for items objects that can be converted to
7054 an integer using operator.index().
7055
Mark Dickinson64b7e502008-07-16 09:40:03 +00007056- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7057 produced a ValueError instead of giving the correct float.
7058
Eric Smitha5fa5a22008-07-16 00:11:49 +00007059- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7060 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7061
Mark Dickinson7103aa42008-07-15 19:08:33 +00007062- Issue #3008: the float type has a new instance method 'float.hex'
7063 and a new class method 'float.fromhex' to convert floating-point
7064 numbers to and from hexadecimal strings, respectively.
7065
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007066- Issue #2235: __hash__ is once again inherited by default. To allow
7067 collections.Hashable to remain meaningful in the presence of the
7068 default hash implementation (object.__hash__), it is now possible
7069 to explicit block inheritance of hash by setting __hash__=None at
7070 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7071 level.
7072
Nick Coghlanb028f502008-07-13 14:52:36 +00007073- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7074 the parent module cannot be found while performing an absolute import.
7075 This means that an incorrectly defined __package__ attribute will
7076 now only prevent relative imports in that module rather than causing
7077 all imports from that module to fail.
7078
Nick Coghlan14ff9942008-07-08 14:21:42 +00007079- Issue #2517: Allow unicode messages in Exceptions again by correctly
7080 bypassing the instance dictionary when looking up __unicode__ on
7081 new-style classes.
7082
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007083- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7084 set to a custom object whose write() method happens to install
7085 another file in sys.stdout.
7086
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007087- Issue #3088: Corrected a race condition in classes derived from
7088 threading.local: the first member set by a thread could be saved in
7089 another thread's dictionary.
7090
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007091- Issue #3004: Minor change to slice.indices(): the start and stop
7092 arguments are now treated identically, making the behaviour easier
7093 to describe and understand. For example, slice(None, -10,
7094 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7095 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7096 10, -1).
7097
Georg Brandl278fc502008-07-19 12:46:12 +00007098- Issue #3219: Calling a function with repeated keyword arguments,
7099 f(a=2, a=23), would not cause a syntax error. This was a regression
7100 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007101
Georg Brandl278fc502008-07-19 12:46:12 +00007102- Issue #2862: Make int and float freelist management consistent with
7103 other freelists. Changes their CompactFreeList apis into
7104 ClearFreeList apis and calls them via gc.collect().

7110 api functions without holding the GIL, which could lead to a fatal
7111 error when they failed.
7112
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007113- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7547 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007548 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007549
7550 This is controlled by the configure argument ``--with-universal-archs``:
7551
7552 - ``--with-universal-archs=all``: install 4-way universal
7553
7554 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7555
7556 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7557
7558 This option should be used in combination with ``--enable-universalsdk=``.
7559
7560 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 +00007609- Issue #1631171: Re-implement the 'warnings' module in C (the
7610 original Python code has been kept as backup). This will allow for
7611 using the 'warning's machinery in such places as the parser where
7612 use of pure Python code is not possible. Both the ``showarning()``
7613 and ``formatwarning()`` gain an optional 'line' argument which is
7614 not called by default for backwards-compatibility reasons. Setting
7615 ``warnings.showwarning()`` to an implementation that lacks support
7616 for the ``line`` argument will raise a DeprecationWarning.

7640
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007641- The getpass module has been improved on Unix. It now uses /dev/tty
7642 by default and uses stderr instead of stdout. A GetPassWarning is
7643 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007644

Georg Brandl3ee81df2008-05-17 18:14:43 +00007658- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007659 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007679- Issue #2550: The approach used by client/server code for obtaining
7680 ports to listen on in network-oriented tests has been refined in an
7681 effort to facilitate running multiple instances of the entire
7682 regression test suite in parallel without issue.
7683 test_support.bind_port() has been fixed such that it will always
7684 return a unique port -- which wasn't always the case with the
7685 previous implementation, especially if socket options had been set
7686 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7687 new implementation of bind_port() will actually raise an exception
7688 if it is passed an AF_INET/SOCK_STREAM socket with either the
7689 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7690 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7691 the socket it's been passed. This currently only applies to
7692 Windows. This option prevents any other sockets from binding to the
7693 host/port we've bound to, thus removing the possibility of the
7694 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7695 when a second SOCK_STREAM socket binds and accepts to a host/port
7696 that's already been bound by another socket. The optional preferred
7697 port parameter to bind_port() has been removed. Under no
7698 circumstances should tests be hard coding ports!
7699
7700 test_support.find_unused_port() has also been introduced, which will
7701 pass a temporary socket object to bind_port() in order to obtain an
7702 unused port. The temporary socket object is then closed and
7703 deleted, and the port is returned. This method should only be used
7704 for obtaining an unused port in order to pass to an external program
7705 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7706 a parameter to a server-oriented class that doesn't give you direct
7707 access to the underlying socket used.
7708
7709 Finally, test_support.HOST has been introduced, which should be used
7710 for the host argument of any relevant socket calls (i.e. bind and
7711 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007712
7713 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007714 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007715 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7716 test_asynchat and test_socket_ssl.
7717
Georg Brandl3ee81df2008-05-17 18:14:43 +00007718 It is now possible for multiple instances of the regression test
7719 suite to run in parallel without issue.

7986-----------------
7987
Fred Drakea8ee94b2008-03-01 02:45:07 +00007988- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007989 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007990
Georg Brandlad61bc82008-02-23 15:11:18 +00007991- Issue #2067: file.__exit__() now calls subclasses' close() method.
7992
7993- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007994
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007995- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007996 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007997
Eric Smitha73fbe72008-02-23 03:09:44 +00007998- Added the future_builtins module, which contains hex() and oct().
7999 These are the PEP 3127 version of these functions, designed to be
8000 compatible with the hex() and oct() builtins from Python 3.0. They
8001 differ slightly in their output formats from the existing, unchanged
8002 Python 2.6 builtins. The expected usage of the future_builtins
8003 module is:
8004 from future_builtins import hex, oct
8005
Eric Smith7ef40bf2008-02-20 23:34:22 +00008006- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8007 exponents for exponents with absolute value < 100. Follows C99
8008 standard. This is a change on Windows, which would use 3 digits.
8009 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8010 so that any alterations it does to the resulting string will be
8011 available in stringlib/formatter.h (for float.__format__).
8012
Eric Smith5a3c1352008-02-19 13:21:56 +00008013- Implemented PEP 3101, Advanced String Formatting. This adds a new
8014 builtin format(); a format() method for str and unicode; a
8015 __format__() method to object, str, unicode, int, long, float, and
8016 datetime; the class string.Formatter; and the C API
8017 PyObject_Format().
8018
Georg Brandl3ee81df2008-05-17 18:14:43 +00008019- Fixed several potential crashes, all caused by specially crafted
8020 __del__ methods exploiting objects in temporarily inconsistent
8021 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008022
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008023- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008024 prevent a possible crash: an Abstract Base Class would try to access
8025 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008026
Georg Brandl3ee81df2008-05-17 18:14:43 +00008027- Fixed repr() and str() of complex numbers with infinity or nan as
8028 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008029
Georg Brandl3ee81df2008-05-17 18:14:43 +00008030- Clear all free lists during a gc.collect() of the highest generation
8031 in order to allow pymalloc to free more arenas. Python may give back
8032 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008033
Georg Brandl3ee81df2008-05-17 18:14:43 +00008034- Issue #2045: Fix an infinite recursion triggered when printing a
8035 subclass of collections.defaultdict, if its default_factory is set
8036 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008037
Christian Heimesf75dbef2008-02-08 00:11:31 +00008038- Fixed a minor memory leak in dictobject.c. The content of the free
8039 list was not freed on interpreter shutdown.
8040
Georg Brandl21e99f42010-03-07 15:23:59 +00008041- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008042 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008043
Georg Brandl3ee81df2008-05-17 18:14:43 +00008044- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8045 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008046 to compact the internal free lists of pre-allocted ints and floats.
8047
Georg Brandl3ee81df2008-05-17 18:14:43 +00008048- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8049 calls. Python expected the return type int but the fork familie
8050 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008051
Georg Brandl3ee81df2008-05-17 18:14:43 +00008052- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8053 appear in the same code unit.

8062 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008063
Georg Brandl3ee81df2008-05-17 18:14:43 +00008064- Patch #1473257: generator objects gain a gi_code attribute. This is
8065 the same object as the func_code attribute of the function that
8066 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008067
Georg Brandl3ee81df2008-05-17 18:14:43 +00008068- Issue #1920: "while 0" statements were completely removed by the
8069 compiler, even in the presence of an "else" clause, which is
8070 supposed to be run when the condition is false. Now the compiler
8071 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008072
Guido van Rossumeead05f2008-01-24 18:21:02 +00008073- A few crashers fixed: weakref_in_del.py (issue #1377858);
8074 loosing_dict_ref.py (issue #1303614, test67.py);
8075 borrowed_ref_[34].py (not in tracker).
8076
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008077- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008078 suppressed while an extension is loaded by calling SetErrorMode in
8079 dynload_win.c. The error is still reported properly.
8080
Georg Brandl3ee81df2008-05-17 18:14:43 +00008081- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008082 several extension methods and modules do not work without unicode
8083 support.
8084
Georg Brandl26543b12008-01-21 18:36:51 +00008085- Issue #1882: when compiling code from a string, encoding cookies in the
8086 second line of code were not always recognized correctly.
8087
Georg Brandl14404b62008-01-19 19:27:05 +00008088- Issue #1679: "0x" was taken as a valid integer literal.
8089
Georg Brandl6caad7d2008-01-26 14:19:22 +00008090- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008091 added.
8092
Christian Heimesc94e2b52008-01-14 04:13:37 +00008093- sys.float_info / PyFloat_GetInfo: The floating point information
8094 object was converted from a dict to a specialized structseq object.
8095
Georg Brandl3ee81df2008-05-17 18:14:43 +00008096- Patch #1816: Added sys.flags structseq. It exposes the status of
8097 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008098
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099- Objects/structseq.c: Implemented new structseq representation. The
8100 patch makes structseqs (e.g. the return value of os.stat) more
8101 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008102
Georg Brandl3ee81df2008-05-17 18:14:43 +00008103- Patch #1700288: added a type attribute cache that caches method
8104 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008105

Georg Brandl3ee81df2008-05-17 18:14:43 +00008125 and INF. float("nan"), float("inf") and float("-inf") now work on
8126 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008127
Georg Brandl3ee81df2008-05-17 18:14:43 +00008128- Compiler now generates simpler and faster code for dictionary
8129 literals. The oparg for BUILD_MAP now indicates an estimated
8130 dictionary size. There is a new opcode, STORE_MAP, for adding
8131 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008179- Issue #1686386: Tuple's tp_repr did not take into account the
8180 possibility of having a self-referential tuple, which is possible
8181 from C code. Nor did object's tp_str consider that a type's tp_str
8182 could do something that could lead to an inifinite recursion.
8183 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8184 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008186- Issue #1164: It was possible to trigger deadlock when using the
8187 'print' statement to write to a file since the GIL was not released
8188 as needed. Now PyObject_Print() does the right thing along with
8189 various tp_print implementations of the built-in types and those in
8190 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008191
Georg Brandl3ee81df2008-05-17 18:14:43 +00008192- Issue #1147: Exceptions were directly allowing string exceptions in
8193 their throw() method even though string exceptions no longer
8194 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008196- Issue #1096: Prevent a segfault from getting the repr of a very
8197 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008198
Brett Cannon1e534b52007-09-07 04:18:30 +00008199- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008200 PyObject_Call() never calling back out to Python code to trigger
8201 recursion depth updates/checks. Required the creation of a static
8202 RuntimeError instance in case normalizing an exception put the
8203 recursion check value past its limit. Fixes crashers
8204 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008219- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008220 __*__ attributes. (Some already existed, e.g., __doc__ and
8221 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008222
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008223- Add -3 option to the interpreter to warn about features that are
8224 deprecated and will be changed/removed in Python 3.0.
8225
Georg Brandl2134e752007-05-21 20:34:16 +00008226- Patch #1686487: you can now pass any mapping after '**' in function
8227 calls.
8228
Collin Winter62903052007-05-18 23:11:24 +00008229- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008230 "except E as target:". This is to provide forwards compatibility
8231 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008238- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008239 setting a plain string, ie don't expand to single letter identifiers.
8240
Raymond Hettinger13936692007-04-11 18:40:58 +00008241- Request #1191699: Slices can now be pickled.
8242
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008243- Request #1193128: str.translate() now allows a None argument for
8244 translations that only remove characters without re-mapping the
8245 remaining characters.
8246
Georg Brandl5cb76c12007-03-21 09:00:39 +00008247- Patch #1682205: a TypeError while unpacking an iterable is no longer

8249
Neal Norwitzaa754b72007-03-21 06:39:48 +00008250- Remove unused file Python/fmod.c.
8251
Guido van Rossum143b5642007-03-23 04:58:42 +00008252- Bug #1683368: The object.__init__() and object.__new__() methods are
8253 now stricter in rejecting excess arguments. The only time when
8254 either allows excess arguments is when it is not overridden and the
8255 other one is. For backwards compatibility, when both are
8256 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008257 warning later). Also, type.__init__() insists on the same signature
8258 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008259
Georg Brandl3ee81df2008-05-17 18:14:43 +00008260- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8261 object to complex using its __complex__() method before falling back
8262 to the __float__() method. Therefore, the functions in the cmath
8263 module now can operate on objects that define a __complex__()
8264 method.

8275 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008282- Bug #1678647: write a newline after printing an exception in any
8283 case, even when converting the value to a string failed.
8284
Georg Brandl871f1bc2007-03-12 13:17:36 +00008285- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008286 its argument, if it exists. If not, it will work like before. This
8287 allows customizing the output of dir() in the presence of a
8288 __getattr__().

8297 parthensized forms. This means complex(repr(x)) now works instead of
8298 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008299
Georg Brandlaa2321b2007-03-07 00:40:28 +00008300- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008301 makes the filenames the warning module prints much more sensible
8302 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008315- Patch #1674228: when assigning a slice (old-style), check for the
8316 sq_ass_slice instead of the sq_slice slot.
8317
Georg Brandl3ee81df2008-05-17 18:14:43 +00008318- When printing an unraisable error, don't print exceptions. before
8319 the name. This duplicates the behavior whening normally printing
8320 exceptions.

Neal Norwitzdac090d2006-09-05 03:53:08 +00008420- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008421 generator expressions (x for x, in ... ) works again. Fixing this

8948 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009223- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9224 with RFC 3207 and forgets any knowledge obtained from the server not
9225 obtained from the TLS negotiation itself. Patch contributed by Bill
9226 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009227
Georg Brandl3ee81df2008-05-17 18:14:43 +00009228- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009229 that the SMTP.starttls() caller no longer needs to call ehlo()
9230 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009231 does not claim to support starttls. Adds the
9232 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9233 Fenner.

9313 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9314 silently miscode subclasses of those types. Now, it raises a
9315 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009316

Georg Brandl3ee81df2008-05-17 18:14:43 +00009331 time so that opening a database previously created with the DB_DUP
9332 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9333 opens. Specifically: dictionary assignment to a DB object will
9334 replace all values for a given key when the database allows
9335 duplicate values. DB users should use DB.put(k, v) when they want
9336 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009337

9343 characters with ASCII value less than 32. Also, it correctly quotes
9344 dots only if they occur on a single line, as opposed to the previous
9345 behavior of quoting dots if they are the second character of any
9346 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009347
Georg Brandla47337f2007-03-13 12:34:25 +00009348- Bug #1622896: fix a rare corner case where the bz2 module raised an

9674-----
9675
Georg Brandl3ee81df2008-05-17 18:14:43 +00009676- Unified naming convention for free lists and their limits. All free
9677 lists in Object/ are named ``free_list``, the counter ``numfree``
9678 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9679 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009680
Georg Brandl3ee81df2008-05-17 18:14:43 +00009681- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9682 to ``PyTuple_SetItem``, it can be used to populate a brand new
9683 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009684
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009685- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009687- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9688 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9689 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009690
9691- Patch #1720595: add T_BOOL to the range of structmember types.
9692
9693- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9694 ``PyFloat_GetInfo()`` to the float API.
9695
Georg Brandl3ee81df2008-05-17 18:14:43 +00009696- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9697 of w# format code incorrectly truncated the length to an int, even
9698 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9699 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009700
Georg Brandl3ee81df2008-05-17 18:14:43 +00009701- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9702 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009704- PEP 3123: Provide forward compatibility with Python 3.0, while
9705 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9706 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009708- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9709 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009710
9711- Patch #1733960: Allow T_LONGLONG to accept ints.

9718
9719- Fix some leftovers from the conversion from int to Py_ssize_t
9720 (relevant to strings and sequences of more than 2**31 items).
9721
9722- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9723 outside of pystate.c and should not be necessary.
9724
Georg Brandl3ee81df2008-05-17 18:14:43 +00009725- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9726 absolute imports. In earlier versions they might have used relative
9727 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009728
Georg Brandl3ee81df2008-05-17 18:14:43 +00009729- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9730 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009731
Georg Brandl3ee81df2008-05-17 18:14:43 +00009732- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009738- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9739 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9740 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9741 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009742
Georg Brandl3ee81df2008-05-17 18:14:43 +00009743- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00009755- Removed the macfs module. It had been deprecated since Python 2.5.
9756 This lead to the deprecation of macostools.touched() as it relied
9757 solely on macfs and was a no-op under OS X.
