1160
1161- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1162 and later systems as is currently done for Python 3.x installers.
1163 For 2.7.7 only, we will provide three installers:
1164 the legacy deprecated 10.3+ 32-bit-only format;
1165 the newer 10.5+ 32-bit-only format;
1166 and the unchanged 10.6+ 64-/32-bit format.
1167 Although binary installers will no longer be available from
1168 python.org as of 2.7.8, it will still be possible to build from
1169 source on 10.3.9 and 10.4 systems if necessary.
1170 See Mac/BuildScript/README.txt for more information.

Ned Deily18fae3f2013-01-31 01:24:55 -08002550- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
2551 In particular, fix extension module build failures when trying to use
2552 32-bit-only installer Pythons on systems with Xcode 4 (currently
2553 OS X 10.8, 10.7, and optionally 10.6).
2554 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2555 * Since Xcode 4 removes ppc support, extension module builds now
2556 check for ppc compiler support and by default remove ppc and
2557 ppc64 archs when they are not available.
2558 * Extension module builds now revert to using system installed
2559 headers and libs (/usr and /System/Library) if the SDK used
2560 to build the interpreter is not installed or has moved.
2561 * Try to avoid building extension modules with deprecated
2562 and problematic Apple llvm-gcc compiler. If original compiler
2563 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01003000- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003001 has left two versions of customize_compiler, the original in
3002 distutils.sysconfig and another copy in distutils.ccompiler, with some
3003 parts of distutils calling one and others using the other.
3004 Complete the revert back to only having one in distutils.sysconfig as
3005 is the case in 3.x.
3006
Ned Deily0d0ea482012-02-10 12:59:06 +01003007- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3008 Distutils-based packages with C extension modules may fail because
3009 Apple has removed gcc-4.2, the version used to build python.org
3010 64-bit/32-bit Pythons. If the user does not explicitly override
3011 the default C compiler by setting the CC environment variable,
3012 Distutils will now attempt to compile extension modules with clang
3013 if gcc-4.2 is required but not found. Also as a convenience, if
3014 the user does explicitly set CC, substitute its value as the default
3015 compiler in the Distutils LDSHARED configuration variable for OS X.
3016 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3017 SDK, neither of which are available in Xcode 4. This change does not
3018 attempt to override settings to support their use with Xcode 4.)

3269 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3270 interpreter process. This could cause failures in non-Distutils subprocesses
3271 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003272 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003273 deployment target only in the environment of each build subprocess. It is
3274 still possible to globally override the default by setting
3275 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3276 greater or equal to the default value, the value with which the interpreter
3277 was built.

3307 the ticker doesn't have to wind down to zero from the old starting point
3308 before the new interval takes effect. And if the user increases the
3309 interval, it makes sure the new limit takes effect right away rather have an
3310 early task switch before recognizing the new interval.

4769
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004770- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4771 start byte and the continuation byte(s) are now considered invalid, instead
4772 of the number of bytes specified by the start byte.
4773 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4774 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4775 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4776 Previous versions returned a single u'\ufffd'.
4777
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004778- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00004779 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
4780 arises from the "Overriding __eq__ blocks inheritance ..." warning
4781 when turned into an exception: in this case the exception simply
4782 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004783
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004784- Issue #8748: Fix two issues with comparisons between complex and integer
4785 objects. (1) The comparison could incorrectly return True in some cases
4786 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4787 (2) The comparison raised an OverflowError for large integers, leading
4788 to unpredictable exceptions when combining integers and complex objects
4789 in sets or dicts.
4790
Mark Dickinson81336372010-05-30 12:12:25 +00004791- Issue #5211: Implicit coercion for the complex type is now completely
4792 removed. (Coercion for arithmetic operations was already removed in 2.7
4793 alpha 4, but coercion for rich comparisons was accidentally left in.)
4794
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004795- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
4796 and error handler, instead of writing to the C stderr file in utf-8
4797
Georg Brandlfee0f442010-05-22 21:26:21 +00004798- Issue #7902: When using explicit relative import syntax, don't try implicit

Georg Brandlfee0f442010-05-22 21:26:21 +00005171- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5172 with a non-empty format string. This is an effort to future-proof user
5173 code. If a derived class does not currently implement __format__ but later
5174 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005175 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005176 Python 3.3 and it will be an error in Python 3.4.

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005236- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005237 argument `-` which tells it to read files to compile from stdin. Each line is
5238 read on demand and the named file is compiled immediately. (Original patch by
5239 Piotr Ożarowski).

Georg Brandlba83f822010-03-14 09:50:54 +00005662 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00005669 file position when calling `truncate()`. It would previously change the file
5670 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005671 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

5674 class used to represent files stored inside an archive. The new
5675 implementation is significantly faster and can be wrapped in a
5676 ``io.BufferedReader`` object for more speedups. It also solves an issue
5677 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00005768- The ``__complex__()`` method is now looked up on the class of instances to
5769 make it consistent with other special methods.

5773
Mark Dickinson1b34d252010-01-01 17:27:30 +00005774- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005775 DeprecationWarning when passed a float argument where an integer was expected.
5776 These functions and methods now raise TypeError instead. The majority of the
5777 effects of this change are in the extension modules, but some core functions
5778 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5779 and many unicode/str methods.

5795 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00005961- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5962 decimal string that's guaranteed to round back to x under correct rounding
5963 (with round-half-to-even rounding mode). Previously it gave a string based on
5964 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5965 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5966 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00005968- Issue #7117: On almost all platforms: float-to-string and string-to-float
5969 conversions within Python are now correctly rounded. Places these conversions
5970 occur include: str for floats and complex numbers; the float and complex
5971 constructors; old-style and new-style numeric formatting; serialization and
5972 deserialization of floats and complex numbers using marshal, pickle and json;
5973 parsing of float and imaginary literals in Python code; Decimal-to-float
5974 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005975
Georg Brandlba83f822010-03-14 09:50:54 +00005976 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5977 providing correctly-rounded strtod and dtoa C functions. This code is
5978 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5979 the C compiler. There may be a small number of platforms on which correct
5980 operation of this code cannot be guaranteed, so the code is not used: notably,
5981 this applies to platforms where the C double format is not IEEE 754 binary64,
5982 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5983 and Python's configure script is unable to determine how to change the FPU
5984 precision. On these platforms conversions use the platform strtod and dtoa,
5985 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005987- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5988 uses the correctly-rounded string <-> float conversions described above (when
5989 available), and so produces correctly rounded results that will display nicely
5990 under the float repr. There are two related small changes: (1) round now
5991 accepts any class with an ``__index__()`` method for its second argument (but
5992 no longer accepts floats for the second argument), and (2) an excessively
5993 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5994 raises an exception.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007801- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7802 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7803 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7804 ``printf`` function, whereas PyString_FromFormat has an independent
7805 implementation and uses "%zd" on all platforms for size_t values.
7806 This makes a difference on win64, where ``printf`` needs "%Id" to display
7807 64bit values.
7808
Benjamin Peterson97179b02008-09-09 20:55:01 +00007809- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
7810 error.
7811
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007812- Issue #3777: long() applied to a float object now always return a long
7813 object; previously an int would be returned for small values. the __long__
7814 method is allowed to return either an int or a long, but the behaviour of
7815 float objects should not change to respect backward compatibility.
7816
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007817- Issue #3751: str.rpartition would perform a left-partition when called with
7818 a unicode argument.
7819
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00007820- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007822- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00007823 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007824 was correctly parsed but parsing of subsequent arguments failed.
7825
Vinay Sajip35e3b032008-09-01 14:33:59 +00007826- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007827 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7828 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7829 when given a tuple of classes as second argument, were looking up
7830 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7831 type object.
7832
Neal Norwitz18aa3882008-08-24 05:04:52 +00007833- Fix crashes on memory allocation failure found with failmalloc.
7834
7835- Fix memory leaks found with valgrind and update suppressions file.

Christian Heimes7d4c3172008-08-22 19:47:25 +00007841- Silenced another compiler warning about a used but not defined
7842 function 'stringlib_contains_obj'.
7843
Benjamin Peterson712ee922008-08-24 18:10:20 +00007844- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
7845 ``__delslice__``.

7849
Gregory P. Smith980b99b2008-09-07 05:15:18 +00007850- Issue #1204: The configure script now tests for additional libraries

Brett Cannon1eaf0742008-09-02 01:25:16 +00007902 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7903 for catch_warnings() also led to an improvement in the raising of a
7904 DeprecationWarning related to warnings.warn_explicit().
7905

7931 without limit.
7932
Benjamin Peterson37346b22008-08-23 20:27:43 +00007933- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007970What's New in Python 2.6 beta 3?
7971================================
7972
Barry Warsaw07a4a382008-08-21 01:15:08 +00007973*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007974
7975Core and Builtins
7976-----------------
7977
Guido van Rossumf8402962008-08-20 15:01:50 +00007978- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7979 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7980 extensions do not automatically benefit from the class attribute
7981 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7982 to their tp_flags field if they care. This is a backwards
7983 compatibility feature; in 3.0, all types will use the cache by
7984 default.
7985
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007986- Keyword arguments can now follow starred arguments. (``f(a, *args,
7987 keyword=23)`` is now valid syntax.)
7988
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007989- ctypes function pointers that are COM methods have a boolean True
7990 value again.
7991
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007992- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7993 by denying s# to parse objects that have a releasebuffer procedure,
7994 and introducing s*.
7995
Georg Brandl1e13ea92008-08-11 09:07:59 +00007996- Issue #3537: Fix an assertion failure when an empty but presized dict
7997 object was stored in the freelist.
7998
Mark Dickinsonb6467572008-08-04 21:30:09 +00007999- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8000 ValueError consistently across platforms.
8001
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008002- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8003 (64bit Unix, for example), unichr() would truncate its argument and return
8004 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8005
Neal Norwitze7d8be82008-07-31 17:17:14 +00008006- Apply security patches from Apple.
8007
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008008- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8009 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8010
Antoine Pitrou92f82162008-07-25 22:22:08 +00008011- Issue #1819: function calls with several named parameters are now on
8012 average 35% faster (as measured by pybench).
8013
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008014- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8015 the python debugger steps into a class statement: the free variables (local
8016 variables defined in an outer scope) would be deleted from the outer scope.
8017
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008018- Issue #2620: Overflow checking when allocating or reallocating memory
8019 was not always being done properly in some python types and extension
8020 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8021 all been updated to perform better checks and places in the code that
8022 would previously leak memory on the error path when such an allocation
8023 failed have been fixed.

8027
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00008028- Issue #3612: Added some missing basic types in ctypes.wintypes.
8029
Benjamin Petersone977ad42008-08-20 01:42:01 +00008030- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8031 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8032
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008033- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8034 version reported by these tools does not necessarily follow the python
8035 version numbering scheme, so the module is less strict when parsing it.
8036
Nick Coghlanf70385a2008-08-18 12:42:46 +00008037- Issue #2235: Added Py3k warnings for types which will become unhashable
8038 under the stricter __hash__ inheritance rules in 3.0. Several types
8039 which did not meet the rules for hash invariants and were already
8040 unhashable in 3.0 have now been explicitly flagged as unhashable in
8041 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8042 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8043
Brett Cannon88f801d2008-08-18 00:46:22 +00008044- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8045 imported into the module but exposed as part of the module's API.
8046
Brett Cannon7b96f072008-08-18 00:41:11 +00008047- Remove an unneeded import of abc.ABCMeta from 'inspect'.

8052
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00008053- Issue #3575: Incremental decoder's decode function now takes bytearray
8054 by using 's*' instead of 't#'.
8055
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008056- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008057 fails unicode conversion on 2nd parameter. (windows only)
8058
Georg Brandl222e2082010-08-01 22:27:39 +00008059- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00008060 in a redirect.
8061

Brett Cannon721b1452008-08-16 22:00:27 +00008063 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00008064
Facundo Batistaeb90b782008-08-16 14:44:07 +00008065- Issue #2776: fixed small issue when handling an URL with double slash
8066 after a 302 response in the case of not going through a proxy.
8067
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008068- Issue #2676: in the email package, content-type parsing was hanging on
8069 pathological input because of quadratic or exponential behaviour of a
8070 regular expression.
8071
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008072- Issue #3476: binary buffered reading through the new "io" library is now
8073 thread-safe.
8074
Brett Cannonbf3157b2008-08-14 05:00:03 +00008075- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8076 since mimetools itself is deprecated. Because modules are cached, all
8077 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8078
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008079- Issue #3134: shutil referenced undefined WindowsError symbol.
8080
Robert Schuppenies14646332008-08-10 11:01:53 +00008081- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8082 menu entries were not deleted.
8083
Brett Cannon83e81842008-08-09 23:30:55 +00008084- Copied the implementation of reduce() to _functools.reduce() to have a

8157
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008158- Issue #643841: The language reference now provides more detailed

8170-----------------
8171
Georg Brandl3e483f62008-07-16 22:57:41 +00008172- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8173 its methods now allow for items objects that can be converted to
8174 an integer using operator.index().
8175
Mark Dickinson64b7e502008-07-16 09:40:03 +00008176- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8177 produced a ValueError instead of giving the correct float.
8178
Eric Smitha5fa5a22008-07-16 00:11:49 +00008179- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8180 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8181
Mark Dickinson7103aa42008-07-15 19:08:33 +00008182- Issue #3008: the float type has a new instance method 'float.hex'
8183 and a new class method 'float.fromhex' to convert floating-point
8184 numbers to and from hexadecimal strings, respectively.
8185
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008186- Issue #2235: __hash__ is once again inherited by default. To allow
8187 collections.Hashable to remain meaningful in the presence of the
8188 default hash implementation (object.__hash__), it is now possible
8189 to explicit block inheritance of hash by setting __hash__=None at
8190 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8191 level.
8192
Nick Coghlanb028f502008-07-13 14:52:36 +00008193- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8194 the parent module cannot be found while performing an absolute import.
8195 This means that an incorrectly defined __package__ attribute will
8196 now only prevent relative imports in that module rather than causing
8197 all imports from that module to fail.
8198
Nick Coghlan14ff9942008-07-08 14:21:42 +00008199- Issue #2517: Allow unicode messages in Exceptions again by correctly

8209 another thread's dictionary.
8210
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008211- Issue #3004: Minor change to slice.indices(): the start and stop
8212 arguments are now treated identically, making the behaviour easier
8213 to describe and understand. For example, slice(None, -10,
8214 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8215 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8216 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00008218- Issue #3219: Calling a function with repeated keyword arguments,
8219 f(a=2, a=23), would not cause a syntax error. This was a regression
8220 from 2.4 caused by the switch to the new compiler.

8223 other freelists. Changes their CompactFreeList apis into

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008258- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8259 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008260 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008261 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008277- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

8663
Brett Cannonb61d8012008-05-11 23:39:04 +00008664- ``Lib/lib-old`` is now added to sys.path.
8665
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008666- On MacOS X it is now possible to install the framework in 64-bit
8667 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008668 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008669
8670 This is controlled by the configure argument ``--with-universal-archs``:
8671
8672 - ``--with-universal-archs=all``: install 4-way universal
8673
8674 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8675
8676 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8677
8678 This option should be used in combination with ``--enable-universalsdk=``.
8679
8680 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00008688
8689- The PyString functions have been renamed to PyBytes. A batch of
8690 defines were added so that the linker still sees the original
8691 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008729- Issue #1631171: Re-implement the 'warnings' module in C (the
8730 original Python code has been kept as backup). This will allow for
8731 using the 'warning's machinery in such places as the parser where
8732 use of pure Python code is not possible. Both the ``showarning()``
8733 and ``formatwarning()`` gain an optional 'line' argument which is
8734 not called by default for backwards-compatibility reasons. Setting
8735 ``warnings.showwarning()`` to an implementation that lacks support
8736 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00008761- The getpass module has been improved on Unix. It now uses /dev/tty
8762 by default and uses stderr instead of stdout. A GetPassWarning is
8763 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00008764

Georg Brandl3ee81df2008-05-17 18:14:43 +00008778- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008779 extension modules between 32 and 64 bit platforms. See the distutls

8783 threads at once without fear of crashing the Python interpreter. If
8784 file.close() is called while an object is in use by another thread
8785 an IOError exception will be raised and the file will not be closed.
8786
Thomas Hellerf7906482008-04-04 19:43:25 +00008787- The bundled libffi copy is now in sync with the recently released

8792 so the controlled environment will more closely mirror the typical
8793 script environment. This supports setup.py scripts that refer to
8794 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008799- Issue #2550: The approach used by client/server code for obtaining
8800 ports to listen on in network-oriented tests has been refined in an
8801 effort to facilitate running multiple instances of the entire
8802 regression test suite in parallel without issue.
8803 test_support.bind_port() has been fixed such that it will always
8804 return a unique port -- which wasn't always the case with the
8805 previous implementation, especially if socket options had been set
8806 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8807 new implementation of bind_port() will actually raise an exception
8808 if it is passed an AF_INET/SOCK_STREAM socket with either the
8809 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8810 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8811 the socket it's been passed. This currently only applies to
8812 Windows. This option prevents any other sockets from binding to the
8813 host/port we've bound to, thus removing the possibility of the
8814 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8815 when a second SOCK_STREAM socket binds and accepts to a host/port
8816 that's already been bound by another socket. The optional preferred
8817 port parameter to bind_port() has been removed. Under no
8818 circumstances should tests be hard coding ports!
8819
8820 test_support.find_unused_port() has also been introduced, which will
8821 pass a temporary socket object to bind_port() in order to obtain an
8822 unused port. The temporary socket object is then closed and
8823 deleted, and the port is returned. This method should only be used
8824 for obtaining an unused port in order to pass to an external program
8825 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8826 a parameter to a server-oriented class that doesn't give you direct
8827 access to the underlying socket used.
8828
8829 Finally, test_support.HOST has been introduced, which should be used
8830 for the host argument of any relevant socket calls (i.e. bind and
8831 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008832
8833 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008834 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008835 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8836 test_asynchat and test_socket_ssl.
8837
Georg Brandl3ee81df2008-05-17 18:14:43 +00008838 It is now possible for multiple instances of the regression test
8839 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009118- Added the future_builtins module, which contains hex() and oct().
9119 These are the PEP 3127 version of these functions, designed to be
9120 compatible with the hex() and oct() builtins from Python 3.0. They
9121 differ slightly in their output formats from the existing, unchanged
9122 Python 2.6 builtins. The expected usage of the future_builtins
9123 module is:
9124 from future_builtins import hex, oct
9125
Eric Smith7ef40bf2008-02-20 23:34:22 +00009126- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9127 exponents for exponents with absolute value < 100. Follows C99
9128 standard. This is a change on Windows, which would use 3 digits.
9129 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9130 so that any alterations it does to the resulting string will be
9131 available in stringlib/formatter.h (for float.__format__).
9132
Eric Smith5a3c1352008-02-19 13:21:56 +00009133- Implemented PEP 3101, Advanced String Formatting. This adds a new
9134 builtin format(); a format() method for str and unicode; a
9135 __format__() method to object, str, unicode, int, long, float, and
9136 datetime; the class string.Formatter; and the C API
9137 PyObject_Format().
9138
Georg Brandl3ee81df2008-05-17 18:14:43 +00009139- Fixed several potential crashes, all caused by specially crafted
9140 __del__ methods exploiting objects in temporarily inconsistent
9141 state.

9152 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009153
Georg Brandl3ee81df2008-05-17 18:14:43 +00009154- Issue #2045: Fix an infinite recursion triggered when printing a
9155 subclass of collections.defaultdict, if its default_factory is set
9156 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009157
Christian Heimesf75dbef2008-02-08 00:11:31 +00009158- Fixed a minor memory leak in dictobject.c. The content of the free
9159 list was not freed on interpreter shutdown.
9160
Georg Brandl21e99f42010-03-07 15:23:59 +00009161- Limit free list of method and built-in function objects to 256

9165 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009166 to compact the internal free lists of pre-allocted ints and floats.
9167
Georg Brandl3ee81df2008-05-17 18:14:43 +00009168- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9169 calls. Python expected the return type int but the fork familie

Georg Brandl3ee81df2008-05-17 18:14:43 +00009172- Issue #1678380: Fix a bug that identifies 0j and -0j when they
9173 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00009174
Georg Brandl3ee81df2008-05-17 18:14:43 +00009175- Issue #2025: Add tuple.count() and tuple.index() methods to comply
9176 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00009177
Georg Brandl3ee81df2008-05-17 18:14:43 +00009178- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
9179 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00009181- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
9182 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00009183
Georg Brandl3ee81df2008-05-17 18:14:43 +00009184- Patch #1473257: generator objects gain a gi_code attribute. This is
9185 the same object as the func_code attribute of the function that
9186 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009187
Georg Brandl3ee81df2008-05-17 18:14:43 +00009188- Issue #1920: "while 0" statements were completely removed by the
9189 compiler, even in the presence of an "else" clause, which is
9190 supposed to be run when the condition is false. Now the compiler
9191 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009192
Guido van Rossumeead05f2008-01-24 18:21:02 +00009193- A few crashers fixed: weakref_in_del.py (issue #1377858);
9194 loosing_dict_ref.py (issue #1303614, test67.py);
9195 borrowed_ref_[34].py (not in tracker).
9196
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009197- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009198 suppressed while an extension is loaded by calling SetErrorMode in
9199 dynload_win.c. The error is still reported properly.
9200
Georg Brandl3ee81df2008-05-17 18:14:43 +00009201- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009202 several extension methods and modules do not work without unicode
9203 support.
9204
Georg Brandl26543b12008-01-21 18:36:51 +00009205- Issue #1882: when compiling code from a string, encoding cookies in the
9206 second line of code were not always recognized correctly.
9207
Georg Brandl14404b62008-01-19 19:27:05 +00009208- Issue #1679: "0x" was taken as a valid integer literal.
9209
Georg Brandl6caad7d2008-01-26 14:19:22 +00009210- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009211 added.
9212
Christian Heimesc94e2b52008-01-14 04:13:37 +00009213- sys.float_info / PyFloat_GetInfo: The floating point information
9214 object was converted from a dict to a specialized structseq object.
9215
Georg Brandl3ee81df2008-05-17 18:14:43 +00009216- Patch #1816: Added sys.flags structseq. It exposes the status of
9217 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009218
Georg Brandl3ee81df2008-05-17 18:14:43 +00009219- Objects/structseq.c: Implemented new structseq representation. The
9220 patch makes structseqs (e.g. the return value of os.stat) more
9221 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009222
Georg Brandl3ee81df2008-05-17 18:14:43 +00009223- Patch #1700288: added a type attribute cache that caches method
9224 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009225
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009226- Bug #1776: __import__() no longer accepts filenames on any platform.
9227 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009228
Georg Brandlaed6c662008-01-07 17:25:53 +00009229- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9230
Georg Brandl3ee81df2008-05-17 18:14:43 +00009231- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9232 envvar and sys.dont_write_bytecode attribute. All these can be set
9233 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009234
Georg Brandl3ee81df2008-05-17 18:14:43 +00009235- Improve some exception messages when Windows fails to load an
9236 extension module. Now we get for example '%1 is not a valid Win32
9237 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009238
Georg Brandl3ee81df2008-05-17 18:14:43 +00009239- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009241- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9242 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009243
Christian Heimes0a8143f2007-12-18 23:22:54 +00009244- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009245 and INF. float("nan"), float("inf") and float("-inf") now work on
9246 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009247
Georg Brandl3ee81df2008-05-17 18:14:43 +00009248- Compiler now generates simpler and faster code for dictionary
9249 literals. The oparg for BUILD_MAP now indicates an estimated
9250 dictionary size. There is a new opcode, STORE_MAP, for adding
9251 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009261- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009262 SystemError.
9263
Nick Coghlanef01d822007-12-03 12:55:17 +00009264- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00009280- Patch #1739468: Directories and zipfiles containing a __main__.py
9281 file can now be directly executed by passing their name to the
9282 interpreter. The directory/zipfile is automatically inserted as the
9283 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009284
Georg Brandl3ee81df2008-05-17 18:14:43 +00009285- Issue #1265: Fix a problem with sys.settrace, if the tracing
9286 function uses a generator expression when at the same time the
9287 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009288
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009289- sets and frozensets now have an isdisjoint() method.
9290
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009291- optimize the performance of builtin.sum().
9292
Neal Norwitz44f326e2007-10-05 05:29:17 +00009293- Fix warnings found by the new version of the Coverity checker.
9294
Georg Brandl21e99f42010-03-07 15:23:59 +00009295- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009296 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9297 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009298
Georg Brandl3ee81df2008-05-17 18:14:43 +00009299- Issue #1686386: Tuple's tp_repr did not take into account the
9300 possibility of having a self-referential tuple, which is possible
9301 from C code. Nor did object's tp_str consider that a type's tp_str
9302 could do something that could lead to an inifinite recursion.
9303 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9304 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009305
Georg Brandl3ee81df2008-05-17 18:14:43 +00009306- Issue #1164: It was possible to trigger deadlock when using the
9307 'print' statement to write to a file since the GIL was not released
9308 as needed. Now PyObject_Print() does the right thing along with
9309 various tp_print implementations of the built-in types and those in
9310 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009311
Georg Brandl3ee81df2008-05-17 18:14:43 +00009312- Issue #1147: Exceptions were directly allowing string exceptions in
9313 their throw() method even though string exceptions no longer
9314 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009315
Georg Brandl3ee81df2008-05-17 18:14:43 +00009316- Issue #1096: Prevent a segfault from getting the repr of a very
9317 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009318
Brett Cannon1e534b52007-09-07 04:18:30 +00009319- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009320 PyObject_Call() never calling back out to Python code to trigger
9321 recursion depth updates/checks. Required the creation of a static
9322 RuntimeError instance in case normalizing an exception put the
9323 recursion check value past its limit. Fixes crashers
9324 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009325
Georg Brandl3ee81df2008-05-17 18:14:43 +00009326- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00009339- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009340 __*__ attributes. (Some already existed, e.g., __doc__ and
9341 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009342
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009343- Add -3 option to the interpreter to warn about features that are
9344 deprecated and will be changed/removed in Python 3.0.
9345
Georg Brandl2134e752007-05-21 20:34:16 +00009346- Patch #1686487: you can now pass any mapping after '**' in function
9347 calls.
9348
Collin Winter62903052007-05-18 23:11:24 +00009349- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009350 "except E as target:". This is to provide forwards compatibility
9351 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009352
Brett Cannon229cee22007-05-05 01:34:02 +00009353- Deprecate BaseException.message as per PEP 352.
9354
Georg Brandl3ee81df2008-05-17 18:14:43 +00009355- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009356 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009357
Vinay Sajip8549ce32007-05-06 17:53:37 +00009358- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009359 setting a plain string, ie don't expand to single letter identifiers.
9360
Raymond Hettinger13936692007-04-11 18:40:58 +00009361- Request #1191699: Slices can now be pickled.
9362
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009363- Request #1193128: str.translate() now allows a None argument for
9364 translations that only remove characters without re-mapping the
9365 remaining characters.
9366
Georg Brandl5cb76c12007-03-21 09:00:39 +00009367- Patch #1682205: a TypeError while unpacking an iterable is no longer
9368 masked by a generic one with the message "unpack non-sequence".
9369
Neal Norwitzaa754b72007-03-21 06:39:48 +00009370- Remove unused file Python/fmod.c.
9371
Guido van Rossum143b5642007-03-23 04:58:42 +00009372- Bug #1683368: The object.__init__() and object.__new__() methods are
9373 now stricter in rejecting excess arguments. The only time when
9374 either allows excess arguments is when it is not overridden and the
9375 other one is. For backwards compatibility, when both are
9376 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009377 warning later). Also, type.__init__() insists on the same signature
9378 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009379
Georg Brandl3ee81df2008-05-17 18:14:43 +00009380- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9381 object to complex using its __complex__() method before falling back
9382 to the __float__() method. Therefore, the functions in the cmath
9383 module now can operate on objects that define a __complex__()
9384 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009385
Georg Brandl3ee81df2008-05-17 18:14:43 +00009386- Patch #1623563: allow __class__ assignment for classes with
9387 __slots__. The old and the new class are still required to have the
9388 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00009389

9394 ``object.__reduce_ex__()`` is called with an object that is faking
9395 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009396
Georg Brandl3ee81df2008-05-17 18:14:43 +00009397- Patch #1680015: Don't modify __slots__ tuple if it contains an

9401
Georg Brandl7b9c5552007-03-12 14:30:05 +00009402- Bug #1678647: write a newline after printing an exception in any
9403 case, even when converting the value to a string failed.
9404
Georg Brandl871f1bc2007-03-12 13:17:36 +00009405- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009406 its argument, if it exists. If not, it will work like before. This
9407 allows customizing the output of dir() in the presence of a
9408 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00009523- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009541 generator expressions (x for x, in ... ) works again. Fixing this
9542 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00009581- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00009931 the client's request was successfully received, understood, and

9943 work started with create_connection() and timeout in httplib, and
9944 closes patch #723312.
9945
Vinay Sajip8549ce32007-05-06 17:53:37 +00009946- Patch #1676823: Added create_connection() to socket.py, which may be

10064 TestCase and TestSuite subclasses (not instances) are no longer
10065 accepted in TestSuite.addTest(). This should cause no

10067 -- the failure just occurred later, with a more cumbersome
10068 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010451 time so that opening a database previously created with the DB_DUP
10452 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10453 opens. Specifically: dictionary assignment to a DB object will
10454 replace all values for a given key when the database allows
10455 duplicate values. DB users should use DB.put(k, v) when they want
10456 to store duplicates; not DB[k] = v.

10465 behavior of quoting dots if they are the second character of any
10466 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010875- Removed the macfs module. It had been deprecated since Python 2.5.
10876 This lead to the deprecation of macostools.touched() as it relied
10877 solely on macfs and was a no-op under OS X.
