1188
1189- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1190 and later systems as is currently done for Python 3.x installers.
1191 For 2.7.7 only, we will provide three installers:
1192 the legacy deprecated 10.3+ 32-bit-only format;
1193 the newer 10.5+ 32-bit-only format;
1194 and the unchanged 10.6+ 64-/32-bit format.
1195 Although binary installers will no longer be available from
1196 python.org as of 2.7.8, it will still be possible to build from
1197 source on 10.3.9 and 10.4 systems if necessary.
1198 See Mac/BuildScript/README.txt for more information.

2580 32-bit-only installer Pythons on systems with Xcode 4 (currently
2581 OS X 10.8, 10.7, and optionally 10.6).
2582 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2583 * Since Xcode 4 removes ppc support, extension module builds now
2584 check for ppc compiler support and by default remove ppc and
2585 ppc64 archs when they are not available.
2586 * Extension module builds now revert to using system installed
2587 headers and libs (/usr and /System/Library) if the SDK used
2588 to build the interpreter is not installed or has moved.
2589 * Try to avoid building extension modules with deprecated
2590 and problematic Apple llvm-gcc compiler. If original compiler
2591 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01003028- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003029 has left two versions of customize_compiler, the original in
3030 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01003035- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3036 Distutils-based packages with C extension modules may fail because
3037 Apple has removed gcc-4.2, the version used to build python.org
3038 64-bit/32-bit Pythons. If the user does not explicitly override
3039 the default C compiler by setting the CC environment variable,
3040 Distutils will now attempt to compile extension modules with clang
3041 if gcc-4.2 is required but not found. Also as a convenience, if
3042 the user does explicitly set CC, substitute its value as the default
3043 compiler in the Distutils LDSHARED configuration variable for OS X.
3044 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3045 SDK, neither of which are available in Xcode 4. This change does not
3046 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003296- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3297 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3298 interpreter process. This could cause failures in non-Distutils subprocesses
3299 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003300 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003301 deployment target only in the environment of each build subprocess. It is
3302 still possible to globally override the default by setting
3303 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3304 greater or equal to the default value, the value with which the interpreter
3305 was built.

3334 updating the check interval, so if the user decreases the check interval,
3335 the ticker doesn't have to wind down to zero from the old starting point
3336 before the new interval takes effect. And if the user increases the
3337 interval, it makes sure the new limit takes effect right away rather have an
3338 early task switch before recognizing the new interval.

4188 thread-local storage key.
4189
Victor Stinnercaafd772010-09-08 10:51:01 +00004190- Issue #4947: The write() method of sys.stdout and sys.stderr uses their

4192 the same behaviour than the print statement.
4193
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00004194- Issue #9737: Fix a crash when trying to delete a slice or an item from

4208
4209 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
4210 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
4211

4303 with invalid characters after '=' in a Q-encoded word.
4304

4306 received. Now sendall() properly calls signal handlers if necessary,

4319 handles non-blocking readinto() returning None correctly.

4322 SSLSocket.sendto() to match the corresponding socket methods. Also,
4323 fix various SSLSocket methods to raise socket.error rather than an
4324 unhelpful TypeError when called on an unconnected socket. Original patch
4325 by Andrew Bennetts.
4326
Raymond Hettinger74f869e2010-09-13 22:14:36 +00004327- Issue #9826: OrderedDict.__repr__ can now handle self-referential
4328 values: d['x'] = d.
4329
Victor Stinner8fc843b2010-09-17 23:35:50 +00004330- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.

4334
Raymond Hettinger20397532010-09-12 02:11:45 +00004335- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4336 This prevents user-created self-referencing ordered dictionaries from
4337 becoming permanently uncollectable GC garbage. The downside is that
4338 removing __del__ means that the internal doubly-linked list has to wait for
4339 GC collection rather than freeing memory immediately when the refcnt drops
4340 to zero.
4341
Raymond Hettingerffd2a422010-09-10 10:47:22 +00004342- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00004343 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00004344 value.
4345
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004346- Issue #9792: In case of connection failure, socket.create_connection()
4347 would swallow the exception and raise a new one, making it impossible
4348 to fetch the original errno, or to filter timeout errors. Now the
4349 original error is re-raised.
4350
Antoine Pitrouf4f61712010-09-07 16:34:47 +00004351- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
4352 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
4353 be updated back after the system call. Original patch by Brian Brazil.
4354
Antoine Pitroudca9de92010-09-04 17:52:26 +00004355- Issue #1100562: Fix deep-copying of objects derived from the list and

4359 ConfigParser.write.
4360
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00004361- Issue #808164: Fixed socket.close to avoid references to globals, to
4362 avoid issues when socket.close is called from a __del__ method.
4363
Terry Reedyd2d2ae92010-11-11 23:22:19 +00004364- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
4365 can be set to False to turn off the previously undocumented 'popularity'
4366 heuristic. Patch by Terry Reedy and Eli Bendersky
4367
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00004368- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
4369 falling into recursion.
4370
R. David Murray7c4bf552010-08-25 01:45:57 +00004371- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
4372 character years even if the message contains RFC822 two character years.
4373
Daniel Stutzbach91287322010-08-24 21:09:30 +00004374- Issue #8750: Fixed MutableSet's methods to correctly handle

4384
Raymond Hettinger917bba12010-08-22 08:01:58 +00004385- Issue #9214: Set operations on KeysView or ItemsView in the collections
4386 module now correctly return a set. (Patch by Eli Bendersky.)
4387
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00004388- Issue #9617: Signals received during a low-level write operation aren't
4389 ignored by the buffered IO layer anymore.
4390
Benjamin Peterson52c36052010-08-21 03:03:22 +00004391- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
4392 are not held onto after they are deleted elsewhere.
4393
Raymond Hettingera54b2da2010-08-17 19:03:06 +00004394- Issue #9626: the view methods for collections.OrderedDict() were returning
4395 the unordered versions inherited from dict. Those methods are now
4396 overridden to provide ordered views.
4397

4399 comment indicating they are generated. Manually maintained MANIFESTs
4400 without this marker will not be overwritten or removed.
4401
Antoine Pitroue1436d12010-08-12 15:25:51 +00004402- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
4403 and a BadZipfile error is raised if it doesn't match (as used to be the
4404 case in Python 2.5 and earlier).
4405
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00004406- Issue #9550: a BufferedReader could issue an additional read when the
4407 original read request had been satisfied, which could block indefinitely
4408 when the underlying raw IO channel was e.g. a socket. Report and original
4409 patch by Jason V. Miller.
4410
Fred Drake0a1fa0e2010-08-10 13:09:54 +00004411- Issue #9551: Don't raise TypeError when setting the value to None for

4430 This is how it is supposed to work, wget and curl do the same. Previous
4431 behavior was wrong.

4796-----------------
4797
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004798- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4799 start byte and the continuation byte(s) are now considered invalid, instead
4800 of the number of bytes specified by the start byte.
4801 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4802 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4803 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4804 Previous versions returned a single u'\ufffd'.
4805
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004806- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00004807 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
4808 arises from the "Overriding __eq__ blocks inheritance ..." warning
4809 when turned into an exception: in this case the exception simply
4810 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004811
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004812- Issue #8748: Fix two issues with comparisons between complex and integer
4813 objects. (1) The comparison could incorrectly return True in some cases
4814 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4815 (2) The comparison raised an OverflowError for large integers, leading
4816 to unpredictable exceptions when combining integers and complex objects
4817 in sets or dicts.
4818
Mark Dickinson81336372010-05-30 12:12:25 +00004819- Issue #5211: Implicit coercion for the complex type is now completely
4820 removed. (Coercion for arithmetic operations was already removed in 2.7
4821 alpha 4, but coercion for rich comparisons was accidentally left in.)
4822
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004823- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
4824 and error handler, instead of writing to the C stderr file in utf-8
4825
Georg Brandlfee0f442010-05-22 21:26:21 +00004826- Issue #7902: When using explicit relative import syntax, don't try implicit
4827 relative import semantics.

4830 from another thread. Patch by Daniel Stutzbach.

5011 operation raises multiple signals and more than one of those signals is
5012 trapped, the specification determines the order in which the signals should be

5200 with a non-empty format string. This is an effort to future-proof user
5201 code. If a derived class does not currently implement __format__ but later
5202 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005203 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005204 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00005237- Issue #8257: The Decimal construct now accepts a float instance directly,
5238 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005239
5240 >>> Decimal(1.1)
5241 Decimal('1.100000000000000088817841970012523233890533447265625')
5242

Georg Brandlfee0f442010-05-22 21:26:21 +00005254- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5255 InvalidOperation instead of returning False. (Comparisons involving a quiet
5256 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5257 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00005259- Issue #2531: Comparison operations between floats and Decimal instances now
5260 return a result based on the numeric values of the operands; previously they
5261 returned an arbitrary result based on the relative ordering of id(float) and
5262 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005264- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005265 argument `-` which tells it to read files to compile from stdin. Each line is
5266 read on demand and the named file is compiled immediately. (Original patch by
5267 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00005276- Comparisons using one of <, <=, >, >= between a complex instance and a
5277 Fractions instance now raise TypeError instead of returning True/False. This
5278 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5279 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00005383- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
5384 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00005386 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5387 inconsistent: __int__ was used for some integer codes but not for others, and
5388 the set of integer codes for which it was used differed between native packing
5389 and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005696- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005697 file position when calling `truncate()`. It would previously change the file
5698 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005699 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00005701- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
5702 class used to represent files stored inside an archive. The new
5703 implementation is significantly faster and can be wrapped in a
5704 ``io.BufferedReader`` object for more speedups. It also solves an issue
5705 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5718 encoded string for them. This ensures that the upload and register commands
5719 send the correct values to PyPI without any error.

5794-----------------
5795
Georg Brandlba83f822010-03-14 09:50:54 +00005796- The ``__complex__()`` method is now looked up on the class of instances to
5797 make it consistent with other special methods.

5801
Mark Dickinson1b34d252010-01-01 17:27:30 +00005802- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005803 DeprecationWarning when passed a float argument where an integer was expected.
5804 These functions and methods now raise TypeError instead. The majority of the
5805 effects of this change are in the extension modules, but some core functions
5806 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5807 and many unicode/str methods.

5821 of integers: the result of a/b is now correctly rounded for ints a and b (at
5822 least on IEEE 754 platforms), and in particular does not depend on the
5823 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00005832 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00005971- Issue #3382: 'F' formatting for float and complex now convert the result to
5972 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5973 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005974
Georg Brandlba83f822010-03-14 09:50:54 +00005975- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5976 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005977
Georg Brandlba83f822010-03-14 09:50:54 +00005978- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5979 1e-100 used to raise OverflowError, but now gives the requested 120
5980 significant digits instead.

5987 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005988
Georg Brandlba83f822010-03-14 09:50:54 +00005989- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5990 decimal string that's guaranteed to round back to x under correct rounding
5991 (with round-half-to-even rounding mode). Previously it gave a string based on
5992 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5993 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5994 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005995
Georg Brandlba83f822010-03-14 09:50:54 +00005996- Issue #7117: On almost all platforms: float-to-string and string-to-float
5997 conversions within Python are now correctly rounded. Places these conversions
5998 occur include: str for floats and complex numbers; the float and complex
5999 constructors; old-style and new-style numeric formatting; serialization and
6000 deserialization of floats and complex numbers using marshal, pickle and json;
6001 parsing of float and imaginary literals in Python code; Decimal-to-float
6002 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006003
Georg Brandlba83f822010-03-14 09:50:54 +00006004 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6005 providing correctly-rounded strtod and dtoa C functions. This code is
6006 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6007 the C compiler. There may be a small number of platforms on which correct
6008 operation of this code cannot be guaranteed, so the code is not used: notably,
6009 this applies to platforms where the C double format is not IEEE 754 binary64,
6010 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6011 and Python's configure script is unable to determine how to change the FPU
6012 precision. On these platforms conversions use the platform strtod and dtoa,
6013 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006014
Georg Brandlba83f822010-03-14 09:50:54 +00006015- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6016 uses the correctly-rounded string <-> float conversions described above (when
6017 available), and so produces correctly rounded results that will display nicely
6018 under the float repr. There are two related small changes: (1) round now
6019 accepts any class with an ``__index__()`` method for its second argument (but
6020 no longer accepts floats for the second argument), and (2) an excessively
6021 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6022 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00006169- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6170 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6171 but with at least one decimal point and with a default precision
6172 of 12. Previously, the behavior the same but with a default precision of 6.
6173 This more closely matches ``str()``, and reduces surprises when adding
6174 alignment flags to the empty presentation type. This also affects the new
6175 complex.__format__ in the same way.
6176
6177- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
6178 classtype's, even if it was None. property now inserts the __doc__ into the
6179 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00006399- On windows, ``os.chdir()`` given unicode was not working if
6400 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6401 this code path is really executed because I cannot move to such directory on
6402 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006404- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6405 element is temporarily replaced with an equivalent frozenset. But the
6406 eventual KeyError would always report the empty ``frozenset()`` as the missing
6407 key. Now it correctly refers to the initial element.

6428 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00007808 AttributeError instead of RuntimeError, depending in which C API call
7809 exactly the recursion limit is exceeded. Consequently, both exception types

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007827- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7828
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007829- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7830 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7831 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7832 ``printf`` function, whereas PyString_FromFormat has an independent
7833 implementation and uses "%zd" on all platforms for size_t values.
7834 This makes a difference on win64, where ``printf`` needs "%Id" to display
7835 64bit values.
7836
Benjamin Peterson97179b02008-09-09 20:55:01 +00007837- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
7838 error.
7839
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007840- Issue #3777: long() applied to a float object now always return a long
7841 object; previously an int would be returned for small values. the __long__
7842 method is allowed to return either an int or a long, but the behaviour of
7843 float objects should not change to respect backward compatibility.
7844
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007845- Issue #3751: str.rpartition would perform a left-partition when called with
7846 a unicode argument.
7847
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00007848- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00007851 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007852 was correctly parsed but parsing of subsequent arguments failed.
7853
Vinay Sajip35e3b032008-09-01 14:33:59 +00007854- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007855 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7856 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7857 when given a tuple of classes as second argument, were looking up
7858 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7859 type object.
7860
Neal Norwitz18aa3882008-08-24 05:04:52 +00007861- Fix crashes on memory allocation failure found with failmalloc.
7862
7863- Fix memory leaks found with valgrind and update suppressions file.

Brett Cannon672237d2008-09-09 00:49:16 +00007904 return a list or None rather than a custom object.
7905
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00007906- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007930 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7931 for catch_warnings() also led to an improvement in the raising of a
7932 DeprecationWarning related to warnings.warn_explicit().
7933
Benjamin Peterson973e6c22008-09-01 23:12:58 +00007934- The deprecation warnings for the old camelCase threading API were removed.

8004-----------------
8005
Guido van Rossumf8402962008-08-20 15:01:50 +00008006- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8007 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8008 extensions do not automatically benefit from the class attribute
8009 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8010 to their tp_flags field if they care. This is a backwards
8011 compatibility feature; in 3.0, all types will use the cache by
8012 default.
8013
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008014- Keyword arguments can now follow starred arguments. (``f(a, *args,
8015 keyword=23)`` is now valid syntax.)
8016
Thomas Heller0ad5ae02008-08-19 19:25:04 +00008017- ctypes function pointers that are COM methods have a boolean True
8018 value again.
8019
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00008020- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
8021 by denying s# to parse objects that have a releasebuffer procedure,
8022 and introducing s*.
8023
Georg Brandl1e13ea92008-08-11 09:07:59 +00008024- Issue #3537: Fix an assertion failure when an empty but presized dict
8025 object was stored in the freelist.
8026
Mark Dickinsonb6467572008-08-04 21:30:09 +00008027- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8028 ValueError consistently across platforms.
8029
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008030- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8031 (64bit Unix, for example), unichr() would truncate its argument and return
8032 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8033
Neal Norwitze7d8be82008-07-31 17:17:14 +00008034- Apply security patches from Apple.
8035
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008036- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8037 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8038
Antoine Pitrou92f82162008-07-25 22:22:08 +00008039- Issue #1819: function calls with several named parameters are now on
8040 average 35% faster (as measured by pybench).
8041
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008042- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8043 the python debugger steps into a class statement: the free variables (local
8044 variables defined in an outer scope) would be deleted from the outer scope.
8045
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008046- Issue #2620: Overflow checking when allocating or reallocating memory
8047 was not always being done properly in some python types and extension
8048 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8049 all been updated to perform better checks and places in the code that
8050 would previously leak memory on the error path when such an allocation
8051 failed have been fixed.

8055
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00008056- Issue #3612: Added some missing basic types in ctypes.wintypes.
8057
Benjamin Petersone977ad42008-08-20 01:42:01 +00008058- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8059 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8060
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008061- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8062 version reported by these tools does not necessarily follow the python
8063 version numbering scheme, so the module is less strict when parsing it.
8064
Nick Coghlanf70385a2008-08-18 12:42:46 +00008065- Issue #2235: Added Py3k warnings for types which will become unhashable
8066 under the stricter __hash__ inheritance rules in 3.0. Several types
8067 which did not meet the rules for hash invariants and were already
8068 unhashable in 3.0 have now been explicitly flagged as unhashable in
8069 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8070 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8071
Brett Cannon88f801d2008-08-18 00:46:22 +00008072- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8073 imported into the module but exposed as part of the module's API.
8074

8199
Georg Brandl3e483f62008-07-16 22:57:41 +00008200- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8201 its methods now allow for items objects that can be converted to
8202 an integer using operator.index().
8203
Mark Dickinson64b7e502008-07-16 09:40:03 +00008204- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8205 produced a ValueError instead of giving the correct float.
8206
Eric Smitha5fa5a22008-07-16 00:11:49 +00008207- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8208 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8209
Mark Dickinson7103aa42008-07-15 19:08:33 +00008210- Issue #3008: the float type has a new instance method 'float.hex'
8211 and a new class method 'float.fromhex' to convert floating-point
8212 numbers to and from hexadecimal strings, respectively.
8213
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008214- Issue #2235: __hash__ is once again inherited by default. To allow
8215 collections.Hashable to remain meaningful in the presence of the
8216 default hash implementation (object.__hash__), it is now possible
8217 to explicit block inheritance of hash by setting __hash__=None at
8218 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8219 level.
8220
Nick Coghlanb028f502008-07-13 14:52:36 +00008221- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8222 the parent module cannot be found while performing an absolute import.
8223 This means that an incorrectly defined __package__ attribute will
8224 now only prevent relative imports in that module rather than causing
8225 all imports from that module to fail.
8226
Nick Coghlan14ff9942008-07-08 14:21:42 +00008227- Issue #2517: Allow unicode messages in Exceptions again by correctly

8237 another thread's dictionary.
8238
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008239- Issue #3004: Minor change to slice.indices(): the start and stop
8240 arguments are now treated identically, making the behaviour easier
8241 to describe and understand. For example, slice(None, -10,
8242 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8243 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8244 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00008246- Issue #3219: Calling a function with repeated keyword arguments,

8287 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008288 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008289 content-length. The problem had been corrected in the 2.4 branch, but never

8693
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008694- On MacOS X it is now possible to install the framework in 64-bit
8695 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008696 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008697
8698 This is controlled by the configure argument ``--with-universal-archs``:
8699
8700 - ``--with-universal-archs=all``: install 4-way universal
8701
8702 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8703
8704 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8705
8706 This option should be used in combination with ``--enable-universalsdk=``.
8707
8708 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 +00008757- Issue #1631171: Re-implement the 'warnings' module in C (the
8758 original Python code has been kept as backup). This will allow for
8759 using the 'warning's machinery in such places as the parser where
8760 use of pure Python code is not possible. Both the ``showarning()``
8761 and ``formatwarning()`` gain an optional 'line' argument which is
8762 not called by default for backwards-compatibility reasons. Setting
8763 ``warnings.showwarning()`` to an implementation that lacks support
8764 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008827- Issue #2550: The approach used by client/server code for obtaining
8828 ports to listen on in network-oriented tests has been refined in an
8829 effort to facilitate running multiple instances of the entire
8830 regression test suite in parallel without issue.
8831 test_support.bind_port() has been fixed such that it will always
8832 return a unique port -- which wasn't always the case with the
8833 previous implementation, especially if socket options had been set
8834 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8835 new implementation of bind_port() will actually raise an exception
8836 if it is passed an AF_INET/SOCK_STREAM socket with either the
8837 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8838 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8839 the socket it's been passed. This currently only applies to
8840 Windows. This option prevents any other sockets from binding to the
8841 host/port we've bound to, thus removing the possibility of the
8842 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8843 when a second SOCK_STREAM socket binds and accepts to a host/port
8844 that's already been bound by another socket. The optional preferred
8845 port parameter to bind_port() has been removed. Under no
8846 circumstances should tests be hard coding ports!
8847
8848 test_support.find_unused_port() has also been introduced, which will
8849 pass a temporary socket object to bind_port() in order to obtain an
8850 unused port. The temporary socket object is then closed and
8851 deleted, and the port is returned. This method should only be used
8852 for obtaining an unused port in order to pass to an external program
8853 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8854 a parameter to a server-oriented class that doesn't give you direct
8855 access to the underlying socket used.
8856
8857 Finally, test_support.HOST has been introduced, which should be used
8858 for the host argument of any relevant socket calls (i.e. bind and
8859 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008860
8861 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008862 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008863 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8864 test_asynchat and test_socket_ssl.
8865
Georg Brandl3ee81df2008-05-17 18:14:43 +00008866 It is now possible for multiple instances of the regression test
8867 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00008921- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00008922 \Uxxxxxxxx did not accept values outside the Basic Multilingual
8923 Plane. This affected raw unicode literals and the
8924 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
8925 this case, like normal unicode literals and the 'unicode-escape'
8926 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00009146- Added the future_builtins module, which contains hex() and oct().
9147 These are the PEP 3127 version of these functions, designed to be
9148 compatible with the hex() and oct() builtins from Python 3.0. They
9149 differ slightly in their output formats from the existing, unchanged
9150 Python 2.6 builtins. The expected usage of the future_builtins
9151 module is:
9152 from future_builtins import hex, oct
9153
Eric Smith7ef40bf2008-02-20 23:34:22 +00009154- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9155 exponents for exponents with absolute value < 100. Follows C99
9156 standard. This is a change on Windows, which would use 3 digits.
9157 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9158 so that any alterations it does to the resulting string will be
9159 available in stringlib/formatter.h (for float.__format__).

Eric Smith5a3c1352008-02-19 13:21:56 +00009161- Implemented PEP 3101, Advanced String Formatting. This adds a new
9162 builtin format(); a format() method for str and unicode; a
9163 __format__() method to object, str, unicode, int, long, float, and
9164 datetime; the class string.Formatter; and the C API
9165 PyObject_Format().
9166
Georg Brandl3ee81df2008-05-17 18:14:43 +00009167- Fixed several potential crashes, all caused by specially crafted
9168 __del__ methods exploiting objects in temporarily inconsistent
9169 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009212- Patch #1473257: generator objects gain a gi_code attribute. This is
9213 the same object as the func_code attribute of the function that
9214 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009215
Georg Brandl3ee81df2008-05-17 18:14:43 +00009216- Issue #1920: "while 0" statements were completely removed by the
9217 compiler, even in the presence of an "else" clause, which is
9218 supposed to be run when the condition is false. Now the compiler
9219 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009220
Guido van Rossumeead05f2008-01-24 18:21:02 +00009221- A few crashers fixed: weakref_in_del.py (issue #1377858);

9228
Georg Brandl3ee81df2008-05-17 18:14:43 +00009229- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009230 several extension methods and modules do not work without unicode
9231 support.
9232

9237
Georg Brandl6caad7d2008-01-26 14:19:22 +00009238- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009239 added.
9240
Christian Heimesc94e2b52008-01-14 04:13:37 +00009241- sys.float_info / PyFloat_GetInfo: The floating point information
9242 object was converted from a dict to a specialized structseq object.
9243
Georg Brandl3ee81df2008-05-17 18:14:43 +00009244- Patch #1816: Added sys.flags structseq. It exposes the status of
9245 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009246
Georg Brandl3ee81df2008-05-17 18:14:43 +00009247- Objects/structseq.c: Implemented new structseq representation. The
9248 patch makes structseqs (e.g. the return value of os.stat) more
9249 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009250
Georg Brandl3ee81df2008-05-17 18:14:43 +00009251- Patch #1700288: added a type attribute cache that caches method
9252 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009253
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009254- Bug #1776: __import__() no longer accepts filenames on any platform.

9260 envvar and sys.dont_write_bytecode attribute. All these can be set
9261 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009262
Georg Brandl3ee81df2008-05-17 18:14:43 +00009263- Improve some exception messages when Windows fails to load an
9264 extension module. Now we get for example '%1 is not a valid Win32
9265 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00009272- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009273 and INF. float("nan"), float("inf") and float("-inf") now work on
9274 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009275
Georg Brandl3ee81df2008-05-17 18:14:43 +00009276- Compiler now generates simpler and faster code for dictionary

9322
Georg Brandl21e99f42010-03-07 15:23:59 +00009323- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009324 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9325 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009326
Georg Brandl3ee81df2008-05-17 18:14:43 +00009327- Issue #1686386: Tuple's tp_repr did not take into account the
9328 possibility of having a self-referential tuple, which is possible
9329 from C code. Nor did object's tp_str consider that a type's tp_str
9330 could do something that could lead to an inifinite recursion.
9331 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9332 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009333
Georg Brandl3ee81df2008-05-17 18:14:43 +00009334- Issue #1164: It was possible to trigger deadlock when using the
9335 'print' statement to write to a file since the GIL was not released
9336 as needed. Now PyObject_Print() does the right thing along with
9337 various tp_print implementations of the built-in types and those in
9338 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009339

Georg Brandl3ee81df2008-05-17 18:14:43 +00009348 PyObject_Call() never calling back out to Python code to trigger
9349 recursion depth updates/checks. Required the creation of a static
9350 RuntimeError instance in case normalizing an exception put the
9351 recursion check value past its limit. Fixes crashers
9352 infinite_rec_(1|2|4|5).py.

9375 calls.
9376
Collin Winter62903052007-05-18 23:11:24 +00009377- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009378 "except E as target:". This is to provide forwards compatibility

Guido van Rossum143b5642007-03-23 04:58:42 +00009400- Bug #1683368: The object.__init__() and object.__new__() methods are
9401 now stricter in rejecting excess arguments. The only time when
9402 either allows excess arguments is when it is not overridden and the
9403 other one is. For backwards compatibility, when both are
9404 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009405 warning later). Also, type.__init__() insists on the same signature
9406 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009408- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9409 object to complex using its __complex__() method before falling back
9410 to the __float__() method. Therefore, the functions in the cmath
9411 module now can operate on objects that define a __complex__()
9412 method.

9432
Georg Brandl871f1bc2007-03-12 13:17:36 +00009433- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009434 its argument, if it exists. If not, it will work like before. This
9435 allows customizing the output of dir() in the presence of a
9436 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00009448- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009449 makes the filenames the warning module prints much more sensible
9450 when a PYTHONSTARTUP file is used.

9465
Georg Brandl3ee81df2008-05-17 18:14:43 +00009466- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00009518- Bug #1545497: when given an explicit base, int() did ignore NULs
9519 embedded in the string to convert.
9520
Georg Brandl846f73a2006-10-08 07:11:54 +00009521- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00009569 generator expressions (x for x, in ... ) works again. Fixing this

10362
Georg Brandl3ee81df2008-05-17 18:14:43 +000010363- Fix utf-8-sig incremental decoder, which didn't recognise a BOM when
10364 the first chunk fed to the decoder started with a BOM, but was
10365 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010366
Georg Brandl3ee81df2008-05-17 18:14:43 +000010367- The implementation of UnicodeError objects has been simplified

10373 obtained from the TLS negotiation itself. Patch contributed by Bill
10374 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +000010375
Georg Brandl3ee81df2008-05-17 18:14:43 +000010376- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010377 that the SMTP.starttls() caller no longer needs to call ehlo()
10378 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010379 does not claim to support starttls. Adds the
10380 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010423- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010424 works as expected. ``mmap.find`` also takes an optional ``end``

10461 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10462 silently miscode subclasses of those types. Now, it raises a
10463 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010464

Georg Brandl3ee81df2008-05-17 18:14:43 +000010479 time so that opening a database previously created with the DB_DUP
10480 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10481 opens. Specifically: dictionary assignment to a DB object will
10482 replace all values for a given key when the database allows
10483 duplicate values. DB users should use DB.put(k, v) when they want
10484 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010485

10491 characters with ASCII value less than 32. Also, it correctly quotes
10492 dots only if they occur on a single line, as opposed to the previous
10493 behavior of quoting dots if they are the second character of any
10494 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010495

Georg Brandl3ee81df2008-05-17 18:14:43 +000010844- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10845 of w# format code incorrectly truncated the length to an int, even
10846 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10847 incorrect results with huge strings.

10857 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010858
10859- Patch #1733960: Allow T_LONGLONG to accept ints.
10860

10866
10867- Fix some leftovers from the conversion from int to Py_ssize_t
10868 (relevant to strings and sequences of more than 2**31 items).
10869
10870- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10871 outside of pystate.c and should not be necessary.

10874 absolute imports. In earlier versions they might have used relative
10875 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010876
Georg Brandl3ee81df2008-05-17 18:14:43 +000010877- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10878 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010879
Georg Brandl3ee81df2008-05-17 18:14:43 +000010880- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010886- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10887 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10888 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10889 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010903- Removed the macfs module. It had been deprecated since Python 2.5.
10904 This lead to the deprecation of macostools.touched() as it relied
10905 solely on macfs and was a no-op under OS X.
