300 David Edelsohn.
301
Ned Deily8e60f6e2013-05-30 00:14:29 -0700302- Issue #18098: The deprecated OS X Build Applet.app fails to build on
303 OS X 10.8 systems because the Apple-deprecated QuickDraw headers have
304 been removed from Xcode 4. Skip building it in this case.

310 64-bit/32-bit installer for 10.6+. It is no longer necessary
311 to install a third-party version of Tcl/Tk 8.5 to work around the
312 problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
313 and later releases.
314
Ned Deilyf84b5312013-10-25 00:44:46 -0700315- Issue #19019: Change the OS X installer build script to use CFLAGS instead
316 of OPT for special build options. By setting OPT, some compiler-specific
317 options like -fwrapv were overridden and thus not used, which could result
318 in broken interpreters when building with clang.

1366 32-bit-only installer Pythons on systems with Xcode 4 (currently
1367 OS X 10.8, 10.7, and optionally 10.6).
1368 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1369 * Since Xcode 4 removes ppc support, extension module builds now
1370 check for ppc compiler support and by default remove ppc and
1371 ppc64 archs when they are not available.
1372 * Extension module builds now revert to using system installed
1373 headers and libs (/usr and /System/Library) if the SDK used
1374 to build the interpreter is not installed or has moved.
1375 * Try to avoid building extension modules with deprecated
1376 and problematic Apple llvm-gcc compiler. If original compiler
1377 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001801- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001802 has left two versions of customize_compiler, the original in
1803 distutils.sysconfig and another copy in distutils.ccompiler, with some
1804 parts of distutils calling one and others using the other.

Ned Deily0d0ea482012-02-10 12:59:06 +01001808- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1809 Distutils-based packages with C extension modules may fail because
1810 Apple has removed gcc-4.2, the version used to build python.org
1811 64-bit/32-bit Pythons. If the user does not explicitly override
1812 the default C compiler by setting the CC environment variable,
1813 Distutils will now attempt to compile extension modules with clang
1814 if gcc-4.2 is required but not found. Also as a convenience, if
1815 the user does explicitly set CC, substitute its value as the default
1816 compiler in the Distutils LDSHARED configuration variable for OS X.
1817 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1818 SDK, neither of which are available in Xcode 4. This change does not
1819 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002069- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2070 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2071 interpreter process. This could cause failures in non-Distutils subprocesses
2072 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002073 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002074 deployment target only in the environment of each build subprocess. It is
2075 still possible to globally override the default by setting
2076 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2077 greater or equal to the default value, the value with which the interpreter
2078 was built.

2108 the ticker doesn't have to wind down to zero from the old starting point
2109 before the new interval takes effect. And if the user increases the
2110 interval, it makes sure the new limit takes effect right away rather have an
2111 early task switch before recognizing the new interval.

2934 dict are now cleared again. This causes issue #7140 to appear again.
2935
Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00002936- Issue #9869: Make long() and PyNumber_Long return something of type
2937 long for a class whose __long__ method returns a plain int. This
2938 fixes an interpreter crash when initializing an instance of a long
2939 subclass from an object whose __long__ method returns a plain int.

2944 thread-local storage key.
2945
Victor Stinnercaafd772010-09-08 10:51:01 +00002946- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
2947 encoding and errors attributes instead of using utf-8 in strict mode, to get
2948 the same behaviour than the print statement.
2949
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00002950- Issue #9737: Fix a crash when trying to delete a slice or an item from

2964
2965 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2966 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3062 received. Now sendall() properly calls signal handlers if necessary,
3063 and retries sending if these returned successfully, including on sockets

3075 handles non-blocking readinto() returning None correctly.
3076

3078 SSLSocket.sendto() to match the corresponding socket methods. Also,
3079 fix various SSLSocket methods to raise socket.error rather than an
3080 unhelpful TypeError when called on an unconnected socket. Original patch
3081 by Andrew Bennetts.
3082
Raymond Hettinger74f869e2010-09-13 22:14:36 +00003083- Issue #9826: OrderedDict.__repr__ can now handle self-referential
3084 values: d['x'] = d.

3090
Raymond Hettinger20397532010-09-12 02:11:45 +00003091- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3092 This prevents user-created self-referencing ordered dictionaries from
3093 becoming permanently uncollectable GC garbage. The downside is that
3094 removing __del__ means that the internal doubly-linked list has to wait for
3095 GC collection rather than freeing memory immediately when the refcnt drops
3096 to zero.
3097
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003098- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00003099 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003100 value.
3101
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003102- Issue #9792: In case of connection failure, socket.create_connection()
3103 would swallow the exception and raise a new one, making it impossible
3104 to fetch the original errno, or to filter timeout errors. Now the
3105 original error is re-raised.
3106
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003107- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3108 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3109 be updated back after the system call. Original patch by Brian Brazil.
3110
Antoine Pitroudca9de92010-09-04 17:52:26 +00003111- Issue #1100562: Fix deep-copying of objects derived from the list and

3115 ConfigParser.write.
3116
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003117- Issue #808164: Fixed socket.close to avoid references to globals, to
3118 avoid issues when socket.close is called from a __del__ method.
3119
Terry Reedyd2d2ae92010-11-11 23:22:19 +00003120- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
3121 can be set to False to turn off the previously undocumented 'popularity'
3122 heuristic. Patch by Terry Reedy and Eli Bendersky
3123
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003124- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3125 falling into recursion.
3126
R. David Murray7c4bf552010-08-25 01:45:57 +00003127- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3128 character years even if the message contains RFC822 two character years.
3129
Daniel Stutzbach91287322010-08-24 21:09:30 +00003130- Issue #8750: Fixed MutableSet's methods to correctly handle
3131 reflexive operations, namely x -= x and x ^= x.
3132

3140
Raymond Hettinger917bba12010-08-22 08:01:58 +00003141- Issue #9214: Set operations on KeysView or ItemsView in the collections
3142 module now correctly return a set. (Patch by Eli Bendersky.)
3143
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003144- Issue #9617: Signals received during a low-level write operation aren't
3145 ignored by the buffered IO layer anymore.
3146
Benjamin Peterson52c36052010-08-21 03:03:22 +00003147- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3148 are not held onto after they are deleted elsewhere.
3149
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003150- Issue #9626: the view methods for collections.OrderedDict() were returning
3151 the unordered versions inherited from dict. Those methods are now
3152 overridden to provide ordered views.
3153
Éric Araujo0389ae62010-08-14 03:07:46 +00003154- Issue #8688: MANIFEST files created by distutils now include a magic
3155 comment indicating they are generated. Manually maintained MANIFESTs
3156 without this marker will not be overwritten or removed.
3157
Antoine Pitroue1436d12010-08-12 15:25:51 +00003158- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3159 and a BadZipfile error is raised if it doesn't match (as used to be the
3160 case in Python 2.5 and earlier).
3161
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003162- Issue #9550: a BufferedReader could issue an additional read when the
3163 original read request had been satisfied, which could block indefinitely
3164 when the underlying raw IO channel was e.g. a socket. Report and original
3165 patch by Jason V. Miller.
3166
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003167- Issue #9551: Don't raise TypeError when setting the value to None for

3183 PROT_WRITE and PROT_EXEC.
3184
Senthil Kumarane677ecf2010-08-08 11:56:31 +00003185- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
3186 This is how it is supposed to work, wget and curl do the same. Previous
3187 behavior was wrong.
3188
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +00003189- Issue #2944: asyncore doesn't handle connection refused correctly.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003554- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3555 start byte and the continuation byte(s) are now considered invalid, instead
3556 of the number of bytes specified by the start byte.
3557 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3558 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3559 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3560 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003568- Issue #8748: Fix two issues with comparisons between complex and integer
3569 objects. (1) The comparison could incorrectly return True in some cases
3570 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3571 (2) The comparison raised an OverflowError for large integers, leading
3572 to unpredictable exceptions when combining integers and complex objects
3573 in sets or dicts.

3767 operation raises multiple signals and more than one of those signals is
3768 trapped, the specification determines the order in which the signals should be

3956 with a non-empty format string. This is an effort to future-proof user
3957 code. If a derived class does not currently implement __format__ but later
3958 adds its own __format__, it would most likely break user code that had

Georg Brandlfee0f442010-05-22 21:26:21 +00003993- Issue #8257: The Decimal construct now accepts a float instance directly,
3994 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003995
3996 >>> Decimal(1.1)
3997 Decimal('1.100000000000000088817841970012523233890533447265625')

4011 InvalidOperation instead of returning False. (Comparisons involving a quiet
4012 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4013 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00004015- Issue #2531: Comparison operations between floats and Decimal instances now
4016 return a result based on the numeric values of the operands; previously they
4017 returned an arbitrary result based on the relative ordering of id(float) and
4018 id(Decimal).

4022 read on demand and the named file is compiled immediately. (Original patch by
4023 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00004032- Comparisons using one of <, <=, >, >= between a complex instance and a
4033 Fractions instance now raise TypeError instead of returning True/False. This
4034 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4035 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004139- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4140 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00004142 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4143 inconsistent: __int__ was used for some integer codes but not for others, and
4144 the set of integer codes for which it was used differed between native packing
4145 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004457- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4458 class used to represent files stored inside an archive. The new
4459 implementation is significantly faster and can be wrapped in a
4460 ``io.BufferedReader`` object for more speedups. It also solves an issue
4461 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4557
Mark Dickinson1b34d252010-01-01 17:27:30 +00004558- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004559 DeprecationWarning when passed a float argument where an integer was expected.
4560 These functions and methods now raise TypeError instead. The majority of the
4561 effects of this change are in the extension modules, but some core functions
4562 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4563 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004727- Issue #3382: 'F' formatting for float and complex now convert the result to
4728 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4729 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004730
Georg Brandlba83f822010-03-14 09:50:54 +00004731- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4732 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004733
Georg Brandlba83f822010-03-14 09:50:54 +00004734- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4735 1e-100 used to raise OverflowError, but now gives the requested 120
4736 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004745- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4746 decimal string that's guaranteed to round back to x under correct rounding
4747 (with round-half-to-even rounding mode). Previously it gave a string based on
4748 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4749 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4750 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004751
Georg Brandlba83f822010-03-14 09:50:54 +00004752- Issue #7117: On almost all platforms: float-to-string and string-to-float
4753 conversions within Python are now correctly rounded. Places these conversions
4754 occur include: str for floats and complex numbers; the float and complex
4755 constructors; old-style and new-style numeric formatting; serialization and
4756 deserialization of floats and complex numbers using marshal, pickle and json;
4757 parsing of float and imaginary literals in Python code; Decimal-to-float
4758 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004759
Georg Brandlba83f822010-03-14 09:50:54 +00004760 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4761 providing correctly-rounded strtod and dtoa C functions. This code is
4762 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4763 the C compiler. There may be a small number of platforms on which correct
4764 operation of this code cannot be guaranteed, so the code is not used: notably,
4765 this applies to platforms where the C double format is not IEEE 754 binary64,
4766 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4767 and Python's configure script is unable to determine how to change the FPU
4768 precision. On these platforms conversions use the platform strtod and dtoa,
4769 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004770
Georg Brandlba83f822010-03-14 09:50:54 +00004771- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4772 uses the correctly-rounded string <-> float conversions described above (when
4773 available), and so produces correctly rounded results that will display nicely
4774 under the float repr. There are two related small changes: (1) round now
4775 accepts any class with an ``__index__()`` method for its second argument (but
4776 no longer accepts floats for the second argument), and (2) an excessively
4777 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4778 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004925- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4926 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4927 but with at least one decimal point and with a default precision
4928 of 12. Previously, the behavior the same but with a default precision of 6.
4929 This more closely matches ``str()``, and reduces surprises when adding
4930 alignment flags to the empty presentation type. This also affects the new
4931 complex.__format__ in the same way.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006562- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6563
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006564- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6565 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6566 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6567 ``printf`` function, whereas PyString_FromFormat has an independent
6568 implementation and uses "%zd" on all platforms for size_t values.
6569 This makes a difference on win64, where ``printf`` needs "%Id" to display
6570 64bit values.
6571
Benjamin Peterson97179b02008-09-09 20:55:01 +00006572- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6573 error.
6574
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006575- Issue #3777: long() applied to a float object now always return a long
6576 object; previously an int would be returned for small values. the __long__
6577 method is allowed to return either an int or a long, but the behaviour of
6578 float objects should not change to respect backward compatibility.
6579
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006580- Issue #3751: str.rpartition would perform a left-partition when called with
6581 a unicode argument.
6582
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006583- Issue #3683: Fix compilation when --without-threads is given.
6584
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006585- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006586 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006587 was correctly parsed but parsing of subsequent arguments failed.
6588
Vinay Sajip35e3b032008-09-01 14:33:59 +00006589- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006590 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6591 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6592 when given a tuple of classes as second argument, were looking up
6593 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6594 type object.
6595
Neal Norwitz18aa3882008-08-24 05:04:52 +00006596- Fix crashes on memory allocation failure found with failmalloc.
6597
6598- Fix memory leaks found with valgrind and update suppressions file.
6599
6600- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6601
6602- Fix problem using wrong name in decimal module reported by pychecker.
6603
Christian Heimes7d4c3172008-08-22 19:47:25 +00006604- Silenced another compiler warning about a used but not defined
6605 function 'stringlib_contains_obj'.
6606
Benjamin Peterson712ee922008-08-24 18:10:20 +00006607- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6608 ``__delslice__``.
6609
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006610- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6611 library targets in the Makefile.
6612
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006613- Issue #1204: The configure script now tests for additional libraries
6614 that may be required when linking against readline. This fixes issues
6615 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00006665 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6666 for catch_warnings() also led to an improvement in the raising of a
6667 DeprecationWarning related to warnings.warn_explicit().
6668
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006669- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006733What's New in Python 2.6 beta 3?
6734================================
6735
Barry Warsaw07a4a382008-08-21 01:15:08 +00006736*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006737
6738Core and Builtins
6739-----------------
6740
Guido van Rossumf8402962008-08-20 15:01:50 +00006741- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6742 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6743 extensions do not automatically benefit from the class attribute
6744 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6745 to their tp_flags field if they care. This is a backwards
6746 compatibility feature; in 3.0, all types will use the cache by
6747 default.
6748
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006749- Keyword arguments can now follow starred arguments. (``f(a, *args,
6750 keyword=23)`` is now valid syntax.)
6751
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006752- ctypes function pointers that are COM methods have a boolean True
6753 value again.
6754
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006755- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6756 by denying s# to parse objects that have a releasebuffer procedure,
6757 and introducing s*.
6758
Georg Brandl1e13ea92008-08-11 09:07:59 +00006759- Issue #3537: Fix an assertion failure when an empty but presized dict
6760 object was stored in the freelist.
6761
Mark Dickinsonb6467572008-08-04 21:30:09 +00006762- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6763 ValueError consistently across platforms.
6764
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006765- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6766 (64bit Unix, for example), unichr() would truncate its argument and return
6767 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6768
Neal Norwitze7d8be82008-07-31 17:17:14 +00006769- Apply security patches from Apple.
6770
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006771- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6772 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6773
Antoine Pitrou92f82162008-07-25 22:22:08 +00006774- Issue #1819: function calls with several named parameters are now on
6775 average 35% faster (as measured by pybench).
6776
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006777- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6778 the python debugger steps into a class statement: the free variables (local
6779 variables defined in an outer scope) would be deleted from the outer scope.
6780
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006781- Issue #2620: Overflow checking when allocating or reallocating memory
6782 was not always being done properly in some python types and extension
6783 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6784 all been updated to perform better checks and places in the code that
6785 would previously leak memory on the error path when such an allocation
6786 failed have been fixed.

6794 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6795
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006796- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6797 version reported by these tools does not necessarily follow the python
6798 version numbering scheme, so the module is less strict when parsing it.
6799
Nick Coghlanf70385a2008-08-18 12:42:46 +00006800- Issue #2235: Added Py3k warnings for types which will become unhashable
6801 under the stricter __hash__ inheritance rules in 3.0. Several types
6802 which did not meet the rules for hash invariants and were already
6803 unhashable in 3.0 have now been explicitly flagged as unhashable in
6804 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6805 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6806
Brett Cannon88f801d2008-08-18 00:46:22 +00006807- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6808 imported into the module but exposed as part of the module's API.
6809

6815
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006816- Issue #3575: Incremental decoder's decode function now takes bytearray
6817 by using 's*' instead of 't#'.
6818
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006819- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006820 fails unicode conversion on 2nd parameter. (windows only)
6821
Georg Brandl222e2082010-08-01 22:27:39 +00006822- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006823 in a redirect.
6824

Brett Cannon721b1452008-08-16 22:00:27 +00006826 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006827
Facundo Batistaeb90b782008-08-16 14:44:07 +00006828- Issue #2776: fixed small issue when handling an URL with double slash
6829 after a 302 response in the case of not going through a proxy.
6830
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006831- Issue #2676: in the email package, content-type parsing was hanging on
6832 pathological input because of quadratic or exponential behaviour of a
6833 regular expression.
6834
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006835- Issue #3476: binary buffered reading through the new "io" library is now

6920
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006921- Issue #643841: The language reference now provides more detailed

6934
Georg Brandl3e483f62008-07-16 22:57:41 +00006935- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6936 its methods now allow for items objects that can be converted to
6937 an integer using operator.index().
6938
Mark Dickinson64b7e502008-07-16 09:40:03 +00006939- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6940 produced a ValueError instead of giving the correct float.
6941
Eric Smitha5fa5a22008-07-16 00:11:49 +00006942- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

6944
Mark Dickinson7103aa42008-07-15 19:08:33 +00006945- Issue #3008: the float type has a new instance method 'float.hex'
6946 and a new class method 'float.fromhex' to convert floating-point
6947 numbers to and from hexadecimal strings, respectively.
6948
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006949- Issue #2235: __hash__ is once again inherited by default. To allow
6950 collections.Hashable to remain meaningful in the presence of the
6951 default hash implementation (object.__hash__), it is now possible
6952 to explicit block inheritance of hash by setting __hash__=None at
6953 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6954 level.
6955
Nick Coghlanb028f502008-07-13 14:52:36 +00006956- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6957 the parent module cannot be found while performing an absolute import.
6958 This means that an incorrectly defined __package__ attribute will
6959 now only prevent relative imports in that module rather than causing
6960 all imports from that module to fail.
6961
Nick Coghlan14ff9942008-07-08 14:21:42 +00006962- Issue #2517: Allow unicode messages in Exceptions again by correctly

6972 another thread's dictionary.
6973
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006974- Issue #3004: Minor change to slice.indices(): the start and stop
6975 arguments are now treated identically, making the behaviour easier
6976 to describe and understand. For example, slice(None, -10,
6977 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6978 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6979 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00006981- Issue #3219: Calling a function with repeated keyword arguments,

6983 from 2.4 caused by the switch to the new compiler.

7022 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007023 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007024 content-length. The problem had been corrected in the 2.4 branch, but never

Vinay Sajip9828b7e2008-06-17 11:04:02 +00007409- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007410 environment to control the '-arch' flags that are used to build
7411 an extension. This was added for compatibility with Apple's build
7412 of Python.
7413
7414- The bundled OSX-specific copy of libbffi is now in sync with the version
7415 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
7416
Georg Brandl25c34082008-08-18 23:09:49 +00007417- The threading module gained aliases for names that will be removed in the

7426
Brett Cannonb61d8012008-05-11 23:39:04 +00007427- ``Lib/lib-old`` is now added to sys.path.
7428
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007429- On MacOS X it is now possible to install the framework in 64-bit
7430 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007431 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007432
7433 This is controlled by the configure argument ``--with-universal-archs``:
7434
7435 - ``--with-universal-archs=all``: install 4-way universal
7436
7437 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7438
7439 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7440
7441 This option should be used in combination with ``--enable-universalsdk=``.
7442
7443 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 +00007492- Issue #1631171: Re-implement the 'warnings' module in C (the
7493 original Python code has been kept as backup). This will allow for
7494 using the 'warning's machinery in such places as the parser where
7495 use of pure Python code is not possible. Both the ``showarning()``
7496 and ``formatwarning()`` gain an optional 'line' argument which is
7497 not called by default for backwards-compatibility reasons. Setting
7498 ``warnings.showwarning()`` to an implementation that lacks support
7499 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007541- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007542 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007562- Issue #2550: The approach used by client/server code for obtaining
7563 ports to listen on in network-oriented tests has been refined in an
7564 effort to facilitate running multiple instances of the entire
7565 regression test suite in parallel without issue.
7566 test_support.bind_port() has been fixed such that it will always
7567 return a unique port -- which wasn't always the case with the
7568 previous implementation, especially if socket options had been set
7569 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7570 new implementation of bind_port() will actually raise an exception
7571 if it is passed an AF_INET/SOCK_STREAM socket with either the
7572 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7573 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7574 the socket it's been passed. This currently only applies to
7575 Windows. This option prevents any other sockets from binding to the
7576 host/port we've bound to, thus removing the possibility of the
7577 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7578 when a second SOCK_STREAM socket binds and accepts to a host/port
7579 that's already been bound by another socket. The optional preferred
7580 port parameter to bind_port() has been removed. Under no
7581 circumstances should tests be hard coding ports!
7582
7583 test_support.find_unused_port() has also been introduced, which will
7584 pass a temporary socket object to bind_port() in order to obtain an
7585 unused port. The temporary socket object is then closed and
7586 deleted, and the port is returned. This method should only be used
7587 for obtaining an unused port in order to pass to an external program
7588 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7589 a parameter to a server-oriented class that doesn't give you direct
7590 access to the underlying socket used.
7591
7592 Finally, test_support.HOST has been introduced, which should be used
7593 for the host argument of any relevant socket calls (i.e. bind and
7594 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007595
7596 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007597 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007598 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7599 test_asynchat and test_socket_ssl.
7600
Georg Brandl3ee81df2008-05-17 18:14:43 +00007601 It is now possible for multiple instances of the regression test
7602 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007881- Added the future_builtins module, which contains hex() and oct().
7882 These are the PEP 3127 version of these functions, designed to be
7883 compatible with the hex() and oct() builtins from Python 3.0. They
7884 differ slightly in their output formats from the existing, unchanged
7885 Python 2.6 builtins. The expected usage of the future_builtins
7886 module is:
7887 from future_builtins import hex, oct
7888
Eric Smith7ef40bf2008-02-20 23:34:22 +00007889- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7890 exponents for exponents with absolute value < 100. Follows C99
7891 standard. This is a change on Windows, which would use 3 digits.
7892 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7893 so that any alterations it does to the resulting string will be
7894 available in stringlib/formatter.h (for float.__format__).
7895
Eric Smith5a3c1352008-02-19 13:21:56 +00007896- Implemented PEP 3101, Advanced String Formatting. This adds a new
7897 builtin format(); a format() method for str and unicode; a
7898 __format__() method to object, str, unicode, int, long, float, and
7899 datetime; the class string.Formatter; and the C API
7900 PyObject_Format().
7901
Georg Brandl3ee81df2008-05-17 18:14:43 +00007902- Fixed several potential crashes, all caused by specially crafted
7903 __del__ methods exploiting objects in temporarily inconsistent
7904 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00007906- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007907 prevent a possible crash: an Abstract Base Class would try to access
7908 a slot on a registered virtual subclass.

7914 in order to allow pymalloc to free more arenas. Python may give back
7915 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007916
Georg Brandl3ee81df2008-05-17 18:14:43 +00007917- Issue #2045: Fix an infinite recursion triggered when printing a
7918 subclass of collections.defaultdict, if its default_factory is set
7919 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007920
Christian Heimesf75dbef2008-02-08 00:11:31 +00007921- Fixed a minor memory leak in dictobject.c. The content of the free
7922 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00007924- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007925 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007926
Georg Brandl3ee81df2008-05-17 18:14:43 +00007927- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7928 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007929 to compact the internal free lists of pre-allocted ints and floats.
7930
Georg Brandl3ee81df2008-05-17 18:14:43 +00007931- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7932 calls. Python expected the return type int but the fork familie
7933 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007934
Georg Brandl3ee81df2008-05-17 18:14:43 +00007935- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7936 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007937
Georg Brandl3ee81df2008-05-17 18:14:43 +00007938- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7939 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007940
Georg Brandl3ee81df2008-05-17 18:14:43 +00007941- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7942 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007943
Georg Brandl3ee81df2008-05-17 18:14:43 +00007944- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7945 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007946
Georg Brandl3ee81df2008-05-17 18:14:43 +00007947- Patch #1473257: generator objects gain a gi_code attribute. This is
7948 the same object as the func_code attribute of the function that
7949 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007950
Georg Brandl3ee81df2008-05-17 18:14:43 +00007951- Issue #1920: "while 0" statements were completely removed by the
7952 compiler, even in the presence of an "else" clause, which is
7953 supposed to be run when the condition is false. Now the compiler
7954 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007955
Guido van Rossumeead05f2008-01-24 18:21:02 +00007956- A few crashers fixed: weakref_in_del.py (issue #1377858);
7957 loosing_dict_ref.py (issue #1303614, test67.py);
7958 borrowed_ref_[34].py (not in tracker).
7959
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007960- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007961 suppressed while an extension is loaded by calling SetErrorMode in
7962 dynload_win.c. The error is still reported properly.
7963
Georg Brandl3ee81df2008-05-17 18:14:43 +00007964- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007965 several extension methods and modules do not work without unicode
7966 support.
7967
Georg Brandl26543b12008-01-21 18:36:51 +00007968- Issue #1882: when compiling code from a string, encoding cookies in the
7969 second line of code were not always recognized correctly.
7970
Georg Brandl14404b62008-01-19 19:27:05 +00007971- Issue #1679: "0x" was taken as a valid integer literal.
7972
Georg Brandl6caad7d2008-01-26 14:19:22 +00007973- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007974 added.
7975
Christian Heimesc94e2b52008-01-14 04:13:37 +00007976- sys.float_info / PyFloat_GetInfo: The floating point information
7977 object was converted from a dict to a specialized structseq object.
7978
Georg Brandl3ee81df2008-05-17 18:14:43 +00007979- Patch #1816: Added sys.flags structseq. It exposes the status of
7980 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007981
Georg Brandl3ee81df2008-05-17 18:14:43 +00007982- Objects/structseq.c: Implemented new structseq representation. The
7983 patch makes structseqs (e.g. the return value of os.stat) more
7984 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007985
Georg Brandl3ee81df2008-05-17 18:14:43 +00007986- Patch #1700288: added a type attribute cache that caches method
7987 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007988
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007989- Bug #1776: __import__() no longer accepts filenames on any platform.
7990 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007991
Georg Brandlaed6c662008-01-07 17:25:53 +00007992- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7993
Georg Brandl3ee81df2008-05-17 18:14:43 +00007994- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7995 envvar and sys.dont_write_bytecode attribute. All these can be set
7996 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007997
Georg Brandl3ee81df2008-05-17 18:14:43 +00007998- Improve some exception messages when Windows fails to load an
7999 extension module. Now we get for example '%1 is not a valid Win32
8000 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008001
Georg Brandl3ee81df2008-05-17 18:14:43 +00008002- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008004- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8005 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008006
Christian Heimes0a8143f2007-12-18 23:22:54 +00008007- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008008 and INF. float("nan"), float("inf") and float("-inf") now work on
8009 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008010
Georg Brandl3ee81df2008-05-17 18:14:43 +00008011- Compiler now generates simpler and faster code for dictionary
8012 literals. The oparg for BUILD_MAP now indicates an estimated
8013 dictionary size. There is a new opcode, STORE_MAP, for adding
8014 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008015
Georg Brandl3ee81df2008-05-17 18:14:43 +00008016- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008024- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008025 SystemError.
8026
Nick Coghlanef01d822007-12-03 12:55:17 +00008027- PEP 366: Allow explicit relative imports when executing modules
8028 inside packages with the -m switch via a new module level
8029 __package__ attribute.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008043- Patch #1739468: Directories and zipfiles containing a __main__.py
8044 file can now be directly executed by passing their name to the
8045 interpreter. The directory/zipfile is automatically inserted as the
8046 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008047
Georg Brandl3ee81df2008-05-17 18:14:43 +00008048- Issue #1265: Fix a problem with sys.settrace, if the tracing
8049 function uses a generator expression when at the same time the
8050 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008051
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008052- sets and frozensets now have an isdisjoint() method.
8053
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008054- optimize the performance of builtin.sum().
8055
Neal Norwitz44f326e2007-10-05 05:29:17 +00008056- Fix warnings found by the new version of the Coverity checker.
8057
Georg Brandl21e99f42010-03-07 15:23:59 +00008058- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008059 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8060 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008061
Georg Brandl3ee81df2008-05-17 18:14:43 +00008062- Issue #1686386: Tuple's tp_repr did not take into account the
8063 possibility of having a self-referential tuple, which is possible
8064 from C code. Nor did object's tp_str consider that a type's tp_str
8065 could do something that could lead to an inifinite recursion.
8066 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8067 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008068
Georg Brandl3ee81df2008-05-17 18:14:43 +00008069- Issue #1164: It was possible to trigger deadlock when using the
8070 'print' statement to write to a file since the GIL was not released
8071 as needed. Now PyObject_Print() does the right thing along with
8072 various tp_print implementations of the built-in types and those in
8073 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008074
Georg Brandl3ee81df2008-05-17 18:14:43 +00008075- Issue #1147: Exceptions were directly allowing string exceptions in
8076 their throw() method even though string exceptions no longer
8077 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008078
Georg Brandl3ee81df2008-05-17 18:14:43 +00008079- Issue #1096: Prevent a segfault from getting the repr of a very
8080 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008081
Brett Cannon1e534b52007-09-07 04:18:30 +00008082- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008083 PyObject_Call() never calling back out to Python code to trigger
8084 recursion depth updates/checks. Required the creation of a static
8085 RuntimeError instance in case normalizing an exception put the
8086 recursion check value past its limit. Fixes crashers
8087 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008088
Georg Brandl3ee81df2008-05-17 18:14:43 +00008089- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008102- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008103 __*__ attributes. (Some already existed, e.g., __doc__ and
8104 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008105
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008106- Add -3 option to the interpreter to warn about features that are
8107 deprecated and will be changed/removed in Python 3.0.
8108
Georg Brandl2134e752007-05-21 20:34:16 +00008109- Patch #1686487: you can now pass any mapping after '**' in function
8110 calls.
8111
Collin Winter62903052007-05-18 23:11:24 +00008112- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008113 "except E as target:". This is to provide forwards compatibility
8114 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008115
Brett Cannon229cee22007-05-05 01:34:02 +00008116- Deprecate BaseException.message as per PEP 352.
8117
Georg Brandl3ee81df2008-05-17 18:14:43 +00008118- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008119 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008120
Vinay Sajip8549ce32007-05-06 17:53:37 +00008121- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008122 setting a plain string, ie don't expand to single letter identifiers.
8123
Raymond Hettinger13936692007-04-11 18:40:58 +00008124- Request #1191699: Slices can now be pickled.
8125
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008126- Request #1193128: str.translate() now allows a None argument for
8127 translations that only remove characters without re-mapping the
8128 remaining characters.
8129
Georg Brandl5cb76c12007-03-21 09:00:39 +00008130- Patch #1682205: a TypeError while unpacking an iterable is no longer
8131 masked by a generic one with the message "unpack non-sequence".
8132
Neal Norwitzaa754b72007-03-21 06:39:48 +00008133- Remove unused file Python/fmod.c.
8134
Guido van Rossum143b5642007-03-23 04:58:42 +00008135- Bug #1683368: The object.__init__() and object.__new__() methods are
8136 now stricter in rejecting excess arguments. The only time when
8137 either allows excess arguments is when it is not overridden and the
8138 other one is. For backwards compatibility, when both are
8139 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008140 warning later). Also, type.__init__() insists on the same signature
8141 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008142
Georg Brandl3ee81df2008-05-17 18:14:43 +00008143- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8144 object to complex using its __complex__() method before falling back
8145 to the __float__() method. Therefore, the functions in the cmath
8146 module now can operate on objects that define a __complex__()
8147 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008694 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00008735 AttributeError instead of an IOError when the server's response
8736 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009214 time so that opening a database previously created with the DB_DUP
9215 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9216 opens. Specifically: dictionary assignment to a DB object will
9217 replace all values for a given key when the database allows
9218 duplicate values. DB users should use DB.put(k, v) when they want
9219 to store duplicates; not DB[k] = v.

9226 characters with ASCII value less than 32. Also, it correctly quotes
9227 dots only if they occur on a single line, as opposed to the previous
9228 behavior of quoting dots if they are the second character of any
9229 line.
