374 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100379- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
380 Distutils-based packages with C extension modules may fail because
381 Apple has removed gcc-4.2, the version used to build python.org
382 64-bit/32-bit Pythons. If the user does not explicitly override
383 the default C compiler by setting the CC environment variable,
384 Distutils will now attempt to compile extension modules with clang
385 if gcc-4.2 is required but not found. Also as a convenience, if
386 the user does explicitly set CC, substitute its value as the default
387 compiler in the Distutils LDSHARED configuration variable for OS X.
388 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
389 SDK, neither of which are available in Xcode 4. This change does not
390 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700663- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
664 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
665 interpreter process. This could cause failures in non-Distutils subprocesses
666 and was unreliable since tests or user programs could modify the interpreter
667 environment after Distutils set it. Instead, have Distutils set the the
668 deployment target only in the environment of each build subprocess. It is
669 still possible to globally override the default by setting
670 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
671 greater or equal to the default value, the value with which the interpreter
672 was built.

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

1497
Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00001498- Issue #9869: Make long() and PyNumber_Long return something of type
1499 long for a class whose __long__ method returns a plain int. This
1500 fixes an interpreter crash when initializing an instance of a long
1501 subclass from an object whose __long__ method returns a plain int.

1506 thread-local storage key.
1507
Victor Stinnercaafd772010-09-08 10:51:01 +00001508- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
1509 encoding and errors attributes instead of using utf-8 in strict mode, to get
1510 the same behaviour than the print statement.
1511
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00001512- Issue #9737: Fix a crash when trying to delete a slice or an item from
1513 a memoryview object.

1526
1527 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
1528 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

1652
Raymond Hettinger20397532010-09-12 02:11:45 +00001653- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1654 This prevents user-created self-referencing ordered dictionaries from
1655 becoming permanently uncollectable GC garbage. The downside is that
1656 removing __del__ means that the internal doubly-linked list has to wait for
1657 GC collection rather than freeing memory immediately when the refcnt drops
1658 to zero.

1663
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001664- Issue #9792: In case of connection failure, socket.create_connection()

1666 to fetch the original errno, or to filter timeout errors. Now the
1667 original error is re-raised.

Daniel Stutzbach66c981b2010-08-31 20:29:39 +00001679- Issue #808164: Fixed socket.close to avoid references to globals, to

1688
R. David Murray7c4bf552010-08-25 01:45:57 +00001689- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four

1708
Benjamin Peterson52c36052010-08-21 03:03:22 +00001709- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1722 case in Python 2.5 and earlier).
1723
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001724- Issue #9550: a BufferedReader could issue an additional read when the

1726 when the underlying raw IO channel was e.g. a socket. Report and original
1727 patch by Jason V. Miller.

2116
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002117- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2118 start byte and the continuation byte(s) are now considered invalid, instead
2119 of the number of bytes specified by the start byte.
2120 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2121 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2122 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2123 Previous versions returned a single u'\ufffd'.

2127 arises from the "Overriding __eq__ blocks inheritance ..." warning
2128 when turned into an exception: in this case the exception simply
2129 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002131- Issue #8748: Fix two issues with comparisons between complex and integer
2132 objects. (1) The comparison could incorrectly return True in some cases
2133 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2134 (2) The comparison raised an OverflowError for large integers, leading
2135 to unpredictable exceptions when combining integers and complex objects
2136 in sets or dicts.
2137
Mark Dickinson81336372010-05-30 12:12:25 +00002138- Issue #5211: Implicit coercion for the complex type is now completely
2139 removed. (Coercion for arithmetic operations was already removed in 2.7
2140 alpha 4, but coercion for rich comparisons was accidentally left in.)
2141
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002142- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00002145- Issue #7902: When using explicit relative import syntax, don't try implicit

Georg Brandlfee0f442010-05-22 21:26:21 +00002329- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2330 operation raises multiple signals and more than one of those signals is
2331 trapped, the specification determines the order in which the signals should be
2332 handled. In many cases this order wasn't being followed, leading to the wrong
2333 Python exception being raised.

2519 with a non-empty format string. This is an effort to future-proof user
2520 code. If a derived class does not currently implement __format__ but later
2521 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002522 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002523 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002556- Issue #8257: The Decimal construct now accepts a float instance directly,
2557 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002558
2559 >>> Decimal(1.1)
2560 Decimal('1.100000000000000088817841970012523233890533447265625')
2561
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002562- collections.Counter() now supports a subtract() method.
2563
Georg Brandlfee0f442010-05-22 21:26:21 +00002564- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00002567- The functools module also adds cmp_to_key() as a tool to transition old-style
2568 comparison functions to new-style key-functions.

Georg Brandlfee0f442010-05-22 21:26:21 +00002573- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2574 InvalidOperation instead of returning False. (Comparisons involving a quiet
2575 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2576 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00002578- Issue #2531: Comparison operations between floats and Decimal instances now
2579 return a result based on the numeric values of the operands; previously they
2580 returned an arbitrary result based on the relative ordering of id(float) and
2581 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002583- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002584 argument `-` which tells it to read files to compile from stdin. Each line is
2585 read on demand and the named file is compiled immediately. (Original patch by
2586 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00002595- Comparisons using one of <, <=, >, >= between a complex instance and a
2596 Fractions instance now raise TypeError instead of returning True/False. This
2597 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2598 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002702- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2703 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00002705 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2706 inconsistent: __int__ was used for some integer codes but not for others, and
2707 the set of integer codes for which it was used differed between native packing
2708 and standard packing.)

3021 class used to represent files stored inside an archive. The new
3022 implementation is significantly faster and can be wrapped in a
3023 ``io.BufferedReader`` object for more speedups. It also solves an issue
3024 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3037 encoded string for them. This ensures that the upload and register commands
3038 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00003121- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003122 DeprecationWarning when passed a float argument where an integer was expected.
3123 These functions and methods now raise TypeError instead. The majority of the
3124 effects of this change are in the extension modules, but some core functions
3125 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3126 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00003291- Issue #3382: 'F' formatting for float and complex now convert the result to
3292 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3293 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003294
Georg Brandlba83f822010-03-14 09:50:54 +00003295- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3296 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00003298- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3299 1e-100 used to raise OverflowError, but now gives the requested 120
3300 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003309- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3310 decimal string that's guaranteed to round back to x under correct rounding
3311 (with round-half-to-even rounding mode). Previously it gave a string based on
3312 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3313 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3314 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003315
Georg Brandlba83f822010-03-14 09:50:54 +00003316- Issue #7117: On almost all platforms: float-to-string and string-to-float
3317 conversions within Python are now correctly rounded. Places these conversions
3318 occur include: str for floats and complex numbers; the float and complex
3319 constructors; old-style and new-style numeric formatting; serialization and
3320 deserialization of floats and complex numbers using marshal, pickle and json;
3321 parsing of float and imaginary literals in Python code; Decimal-to-float
3322 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003323
Georg Brandlba83f822010-03-14 09:50:54 +00003324 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3325 providing correctly-rounded strtod and dtoa C functions. This code is
3326 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3327 the C compiler. There may be a small number of platforms on which correct
3328 operation of this code cannot be guaranteed, so the code is not used: notably,
3329 this applies to platforms where the C double format is not IEEE 754 binary64,
3330 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3331 and Python's configure script is unable to determine how to change the FPU
3332 precision. On these platforms conversions use the platform strtod and dtoa,
3333 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003335- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3336 uses the correctly-rounded string <-> float conversions described above (when
3337 available), and so produces correctly rounded results that will display nicely
3338 under the float repr. There are two related small changes: (1) round now
3339 accepts any class with an ``__index__()`` method for its second argument (but
3340 no longer accepts floats for the second argument), and (2) an excessively
3341 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3342 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003489- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3490 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3491 but with at least one decimal point and with a default precision
3492 of 12. Previously, the behavior the same but with a default precision of 6.
3493 This more closely matches ``str()``, and reduces surprises when adding
3494 alignment flags to the empty presentation type. This also affects the new
3495 complex.__format__ in the same way.

5121-----------------
5122
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005123- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5124
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005125- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5126 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5127 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5128 ``printf`` function, whereas PyString_FromFormat has an independent
5129 implementation and uses "%zd" on all platforms for size_t values.
5130 This makes a difference on win64, where ``printf`` needs "%Id" to display
5131 64bit values.
5132
Benjamin Peterson97179b02008-09-09 20:55:01 +00005133- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5134 error.
5135
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005136- Issue #3777: long() applied to a float object now always return a long
5137 object; previously an int would be returned for small values. the __long__
5138 method is allowed to return either an int or a long, but the behaviour of
5139 float objects should not change to respect backward compatibility.
5140
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005141- Issue #3751: str.rpartition would perform a left-partition when called with
5142 a unicode argument.
5143
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005144- Issue #3683: Fix compilation when --without-threads is given.
5145
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005146- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005147 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005148 was correctly parsed but parsing of subsequent arguments failed.
5149
Vinay Sajip35e3b032008-09-01 14:33:59 +00005150- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005151 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5152 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5153 when given a tuple of classes as second argument, were looking up
5154 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5155 type object.
5156
Neal Norwitz18aa3882008-08-24 05:04:52 +00005157- Fix crashes on memory allocation failure found with failmalloc.
5158
5159- Fix memory leaks found with valgrind and update suppressions file.
5160
5161- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5162
5163- Fix problem using wrong name in decimal module reported by pychecker.
5164
Christian Heimes7d4c3172008-08-22 19:47:25 +00005165- Silenced another compiler warning about a used but not defined
5166 function 'stringlib_contains_obj'.
5167
Benjamin Peterson712ee922008-08-24 18:10:20 +00005168- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5169 ``__delslice__``.
5170
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005171- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5172 library targets in the Makefile.
5173
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005174- Issue #1204: The configure script now tests for additional libraries
5175 that may be required when linking against readline. This fixes issues
5176 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
5177

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00005186- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
5187 stack usage in the case of deeply nested objects.
5188

Nick Coghland2e09382008-09-11 12:11:06 +00005199- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00005200 return a list or None rather than a custom object.
5201
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005202- Issue #1638033: Cookie.Morsel gained the httponly attribute.
5203
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00005204- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon32476fc2008-09-05 18:33:51 +00005207
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +00005208- Issue #3762: platform.architecture() fails if python is lanched via
5209 its symbolic link.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005226 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5227 for catch_warnings() also led to an improvement in the raising of a
5228 DeprecationWarning related to warnings.warn_explicit().
5229
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005230- The deprecation warnings for the old camelCase threading API were removed.

5252
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005253- Issue #2975: When compiling several extension modules with Visual Studio 2008
5254 from the same python interpreter, some environment variables would grow
5255 without limit.
5256
Benjamin Peterson37346b22008-08-23 20:27:43 +00005257- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5258 exploitation of poor argument checking.
5259
Gerhard Häringef2276b2008-09-12 13:54:06 +00005260- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Nick Coghland2e09382008-09-11 12:11:06 +00005272- Issue #3781: Add test.test_support.check_warnings() as a convenience
5273 wrapper for warnings.catch_warnings() that makes it easier to check
5274 that expected warning messages are being reported.
5275
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00005276- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005298
5299Core and Builtins
5300-----------------
5301
Guido van Rossumf8402962008-08-20 15:01:50 +00005302- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5303 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5304 extensions do not automatically benefit from the class attribute
5305 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5306 to their tp_flags field if they care. This is a backwards
5307 compatibility feature; in 3.0, all types will use the cache by
5308 default.
5309
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005310- Keyword arguments can now follow starred arguments. (``f(a, *args,
5311 keyword=23)`` is now valid syntax.)
5312
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005313- ctypes function pointers that are COM methods have a boolean True
5314 value again.
5315
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005316- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5317 by denying s# to parse objects that have a releasebuffer procedure,
5318 and introducing s*.
5319
Georg Brandl1e13ea92008-08-11 09:07:59 +00005320- Issue #3537: Fix an assertion failure when an empty but presized dict
5321 object was stored in the freelist.
5322
Mark Dickinsonb6467572008-08-04 21:30:09 +00005323- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5324 ValueError consistently across platforms.
5325
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005326- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5327 (64bit Unix, for example), unichr() would truncate its argument and return
5328 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5329
Neal Norwitze7d8be82008-07-31 17:17:14 +00005330- Apply security patches from Apple.
5331
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005332- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5333 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5334
Antoine Pitrou92f82162008-07-25 22:22:08 +00005335- Issue #1819: function calls with several named parameters are now on
5336 average 35% faster (as measured by pybench).
5337
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005338- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5339 the python debugger steps into a class statement: the free variables (local
5340 variables defined in an outer scope) would be deleted from the outer scope.
5341
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005342- Issue #2620: Overflow checking when allocating or reallocating memory
5343 was not always being done properly in some python types and extension
5344 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5345 all been updated to perform better checks and places in the code that
5346 would previously leak memory on the error path when such an allocation
5347 failed have been fixed.

5350-------
5351
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005352- Issue #3612: Added some missing basic types in ctypes.wintypes.
5353
Benjamin Petersone977ad42008-08-20 01:42:01 +00005354- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5355 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5356
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005357- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5358 version reported by these tools does not necessarily follow the python
5359 version numbering scheme, so the module is less strict when parsing it.
5360
Nick Coghlanf70385a2008-08-18 12:42:46 +00005361- Issue #2235: Added Py3k warnings for types which will become unhashable
5362 under the stricter __hash__ inheritance rules in 3.0. Several types
5363 which did not meet the rules for hash invariants and were already
5364 unhashable in 3.0 have now been explicitly flagged as unhashable in
5365 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5366 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5367
Brett Cannon88f801d2008-08-18 00:46:22 +00005368- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5376
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005377- Issue #3575: Incremental decoder's decode function now takes bytearray
5378 by using 's*' instead of 't#'.
5379
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005380- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005381 fails unicode conversion on 2nd parameter. (windows only)
5382
Georg Brandl222e2082010-08-01 22:27:39 +00005383- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005384 in a redirect.
5385
Brett Cannonabe423e2008-08-16 21:47:07 +00005386- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005387 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005388
Facundo Batistaeb90b782008-08-16 14:44:07 +00005389- Issue #2776: fixed small issue when handling an URL with double slash
5390 after a 302 response in the case of not going through a proxy.
5391
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005392- Issue #2676: in the email package, content-type parsing was hanging on
5393 pathological input because of quadratic or exponential behaviour of a
5394 regular expression.
5395
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005396- Issue #3476: binary buffered reading through the new "io" library is now
5397 thread-safe.
5398
Brett Cannonbf3157b2008-08-14 05:00:03 +00005399- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5400 since mimetools itself is deprecated. Because modules are cached, all
5401 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5402

Antoine Pitroude781a42008-08-09 12:43:23 +00005437 asking for a specific length. This problem only affected files opened

5481
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005482- Issue #643841: The language reference now provides more detailed

5494-----------------
5495
Georg Brandl3e483f62008-07-16 22:57:41 +00005496- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5497 its methods now allow for items objects that can be converted to
5498 an integer using operator.index().
5499
Mark Dickinson64b7e502008-07-16 09:40:03 +00005500- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5501 produced a ValueError instead of giving the correct float.
5502
Eric Smitha5fa5a22008-07-16 00:11:49 +00005503- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5504 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5505
Mark Dickinson7103aa42008-07-15 19:08:33 +00005506- Issue #3008: the float type has a new instance method 'float.hex'
5507 and a new class method 'float.fromhex' to convert floating-point
5508 numbers to and from hexadecimal strings, respectively.
5509
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005510- Issue #2235: __hash__ is once again inherited by default. To allow
5511 collections.Hashable to remain meaningful in the presence of the
5512 default hash implementation (object.__hash__), it is now possible
5513 to explicit block inheritance of hash by setting __hash__=None at
5514 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5515 level.
5516
Nick Coghlanb028f502008-07-13 14:52:36 +00005517- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5518 the parent module cannot be found while performing an absolute import.
5519 This means that an incorrectly defined __package__ attribute will
5520 now only prevent relative imports in that module rather than causing
5521 all imports from that module to fail.
5522
Nick Coghlan14ff9942008-07-08 14:21:42 +00005523- Issue #2517: Allow unicode messages in Exceptions again by correctly

5533 another thread's dictionary.
5534
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005535- Issue #3004: Minor change to slice.indices(): the start and stop
5536 arguments are now treated identically, making the behaviour easier
5537 to describe and understand. For example, slice(None, -10,
5538 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5539 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5540 10, -1).
5541
Georg Brandl278fc502008-07-19 12:46:12 +00005542- Issue #3219: Calling a function with repeated keyword arguments,
5543 f(a=2, a=23), would not cause a syntax error. This was a regression
5544 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00005546- Issue #2862: Make int and float freelist management consistent with
5547 other freelists. Changes their CompactFreeList apis into

5554 api functions without holding the GIL, which could lead to a fatal
5555 error when they failed.
5556
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005557- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005582- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5583 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005584 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005585 content-length. The problem had been corrected in the 2.4 branch, but never
5586 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005601- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5970 in Python 3.0.
Benjamin Peterson23681932008-05-12 21:42:13 +00005971
Vinay Sajip9828b7e2008-06-17 11:04:02 +00005972- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005973 environment to control the '-arch' flags that are used to build
5974 an extension. This was added for compatibility with Apple's build
5975 of Python.
5976
5977- The bundled OSX-specific copy of libbffi is now in sync with the version
5978 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
5979
Georg Brandl25c34082008-08-18 23:09:49 +00005980- The threading module gained aliases for names that will be removed in the

5989
Brett Cannonb61d8012008-05-11 23:39:04 +00005990- ``Lib/lib-old`` is now added to sys.path.
5991
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005992- On MacOS X it is now possible to install the framework in 64-bit
5993 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005994 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005995
5996 This is controlled by the configure argument ``--with-universal-archs``:
5997
5998 - ``--with-universal-archs=all``: install 4-way universal
5999
6000 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6001
6002 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6003
6004 This option should be used in combination with ``--enable-universalsdk=``.
6005
6006 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 +00006015
6016- The PyString functions have been renamed to PyBytes. A batch of
6017 defines were added so that the linker still sees the original
6018 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006056- Issue #1631171: Re-implement the 'warnings' module in C (the
6057 original Python code has been kept as backup). This will allow for
6058 using the 'warning's machinery in such places as the parser where
6059 use of pure Python code is not possible. Both the ``showarning()``
6060 and ``formatwarning()`` gain an optional 'line' argument which is
6061 not called by default for backwards-compatibility reasons. Setting
6062 ``warnings.showwarning()`` to an implementation that lacks support
6063 for the ``line`` argument will raise a DeprecationWarning.

6087
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006088- The getpass module has been improved on Unix. It now uses /dev/tty
6089 by default and uses stderr instead of stdout. A GetPassWarning is
6090 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006105- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006106 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006126- Issue #2550: The approach used by client/server code for obtaining
6127 ports to listen on in network-oriented tests has been refined in an
6128 effort to facilitate running multiple instances of the entire
6129 regression test suite in parallel without issue.
6130 test_support.bind_port() has been fixed such that it will always
6131 return a unique port -- which wasn't always the case with the
6132 previous implementation, especially if socket options had been set
6133 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6134 new implementation of bind_port() will actually raise an exception
6135 if it is passed an AF_INET/SOCK_STREAM socket with either the
6136 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6137 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6138 the socket it's been passed. This currently only applies to
6139 Windows. This option prevents any other sockets from binding to the
6140 host/port we've bound to, thus removing the possibility of the
6141 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6142 when a second SOCK_STREAM socket binds and accepts to a host/port
6143 that's already been bound by another socket. The optional preferred
6144 port parameter to bind_port() has been removed. Under no
6145 circumstances should tests be hard coding ports!
6146
6147 test_support.find_unused_port() has also been introduced, which will
6148 pass a temporary socket object to bind_port() in order to obtain an
6149 unused port. The temporary socket object is then closed and
6150 deleted, and the port is returned. This method should only be used
6151 for obtaining an unused port in order to pass to an external program
6152 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6153 a parameter to a server-oriented class that doesn't give you direct
6154 access to the underlying socket used.
6155
6156 Finally, test_support.HOST has been introduced, which should be used
6157 for the host argument of any relevant socket calls (i.e. bind and
6158 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006159
6160 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006161 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006162 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6163 test_asynchat and test_socket_ssl.
6164
Georg Brandl3ee81df2008-05-17 18:14:43 +00006165 It is now possible for multiple instances of the regression test
6166 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006445- Added the future_builtins module, which contains hex() and oct().
6446 These are the PEP 3127 version of these functions, designed to be
6447 compatible with the hex() and oct() builtins from Python 3.0. They
6448 differ slightly in their output formats from the existing, unchanged
6449 Python 2.6 builtins. The expected usage of the future_builtins
6450 module is:
6451 from future_builtins import hex, oct
6452
Eric Smith7ef40bf2008-02-20 23:34:22 +00006453- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6454 exponents for exponents with absolute value < 100. Follows C99
6455 standard. This is a change on Windows, which would use 3 digits.
6456 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6457 so that any alterations it does to the resulting string will be
6458 available in stringlib/formatter.h (for float.__format__).
6459
Eric Smith5a3c1352008-02-19 13:21:56 +00006460- Implemented PEP 3101, Advanced String Formatting. This adds a new
6461 builtin format(); a format() method for str and unicode; a
6462 __format__() method to object, str, unicode, int, long, float, and
6463 datetime; the class string.Formatter; and the C API
6464 PyObject_Format().
6465
Georg Brandl3ee81df2008-05-17 18:14:43 +00006466- Fixed several potential crashes, all caused by specially crafted
6467 __del__ methods exploiting objects in temporarily inconsistent
6468 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00006470- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006471 prevent a possible crash: an Abstract Base Class would try to access
6472 a slot on a registered virtual subclass.

6478 in order to allow pymalloc to free more arenas. Python may give back
6479 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006480
Georg Brandl3ee81df2008-05-17 18:14:43 +00006481- Issue #2045: Fix an infinite recursion triggered when printing a
6482 subclass of collections.defaultdict, if its default_factory is set
6483 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006484
Christian Heimesf75dbef2008-02-08 00:11:31 +00006485- Fixed a minor memory leak in dictobject.c. The content of the free
6486 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00006488- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006489 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006490
Georg Brandl3ee81df2008-05-17 18:14:43 +00006491- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6492 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006493 to compact the internal free lists of pre-allocted ints and floats.
6494
Georg Brandl3ee81df2008-05-17 18:14:43 +00006495- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6496 calls. Python expected the return type int but the fork familie
6497 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006498
Georg Brandl3ee81df2008-05-17 18:14:43 +00006499- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6500 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006501
Georg Brandl3ee81df2008-05-17 18:14:43 +00006502- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6503 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006504
Georg Brandl3ee81df2008-05-17 18:14:43 +00006505- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6506 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00006508- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6509 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006510
Georg Brandl3ee81df2008-05-17 18:14:43 +00006511- Patch #1473257: generator objects gain a gi_code attribute. This is
6512 the same object as the func_code attribute of the function that
6513 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006514
Georg Brandl3ee81df2008-05-17 18:14:43 +00006515- Issue #1920: "while 0" statements were completely removed by the
6516 compiler, even in the presence of an "else" clause, which is
6517 supposed to be run when the condition is false. Now the compiler
6518 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006519
Guido van Rossumeead05f2008-01-24 18:21:02 +00006520- A few crashers fixed: weakref_in_del.py (issue #1377858);
6521 loosing_dict_ref.py (issue #1303614, test67.py);
6522 borrowed_ref_[34].py (not in tracker).
6523
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006524- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006525 suppressed while an extension is loaded by calling SetErrorMode in
6526 dynload_win.c. The error is still reported properly.
6527
Georg Brandl3ee81df2008-05-17 18:14:43 +00006528- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006529 several extension methods and modules do not work without unicode
6530 support.
6531
Georg Brandl26543b12008-01-21 18:36:51 +00006532- Issue #1882: when compiling code from a string, encoding cookies in the
6533 second line of code were not always recognized correctly.
6534
Georg Brandl14404b62008-01-19 19:27:05 +00006535- Issue #1679: "0x" was taken as a valid integer literal.
6536
Georg Brandl6caad7d2008-01-26 14:19:22 +00006537- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006538 added.
6539
Christian Heimesc94e2b52008-01-14 04:13:37 +00006540- sys.float_info / PyFloat_GetInfo: The floating point information
6541 object was converted from a dict to a specialized structseq object.
6542
Georg Brandl3ee81df2008-05-17 18:14:43 +00006543- Patch #1816: Added sys.flags structseq. It exposes the status of
6544 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006545
Georg Brandl3ee81df2008-05-17 18:14:43 +00006546- Objects/structseq.c: Implemented new structseq representation. The
6547 patch makes structseqs (e.g. the return value of os.stat) more
6548 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006549
Georg Brandl3ee81df2008-05-17 18:14:43 +00006550- Patch #1700288: added a type attribute cache that caches method
6551 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006552
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006553- Bug #1776: __import__() no longer accepts filenames on any platform.
6554 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006555
Georg Brandlaed6c662008-01-07 17:25:53 +00006556- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6557
Georg Brandl3ee81df2008-05-17 18:14:43 +00006558- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6559 envvar and sys.dont_write_bytecode attribute. All these can be set
6560 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006561
Georg Brandl3ee81df2008-05-17 18:14:43 +00006562- Improve some exception messages when Windows fails to load an
6563 extension module. Now we get for example '%1 is not a valid Win32
6564 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006565
Georg Brandl3ee81df2008-05-17 18:14:43 +00006566- Bug #1481296: Fixed long(float('nan')) != 0L.

6569 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006570
Christian Heimes0a8143f2007-12-18 23:22:54 +00006571- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006572 and INF. float("nan"), float("inf") and float("-inf") now work on
6573 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006574
Georg Brandl3ee81df2008-05-17 18:14:43 +00006575- Compiler now generates simpler and faster code for dictionary
6576 literals. The oparg for BUILD_MAP now indicates an estimated
6577 dictionary size. There is a new opcode, STORE_MAP, for adding
6578 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006579
Georg Brandl3ee81df2008-05-17 18:14:43 +00006580- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006588- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006589 SystemError.
6590
Nick Coghlanef01d822007-12-03 12:55:17 +00006591- PEP 366: Allow explicit relative imports when executing modules
6592 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00006607- Patch #1739468: Directories and zipfiles containing a __main__.py
6608 file can now be directly executed by passing their name to the
6609 interpreter. The directory/zipfile is automatically inserted as the
6610 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006611
Georg Brandl3ee81df2008-05-17 18:14:43 +00006612- Issue #1265: Fix a problem with sys.settrace, if the tracing
6613 function uses a generator expression when at the same time the
6614 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006615
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006616- sets and frozensets now have an isdisjoint() method.
6617
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006618- optimize the performance of builtin.sum().
6619
Neal Norwitz44f326e2007-10-05 05:29:17 +00006620- Fix warnings found by the new version of the Coverity checker.
6621
Georg Brandl21e99f42010-03-07 15:23:59 +00006622- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006623 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6624 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006625
Georg Brandl3ee81df2008-05-17 18:14:43 +00006626- Issue #1686386: Tuple's tp_repr did not take into account the
6627 possibility of having a self-referential tuple, which is possible
6628 from C code. Nor did object's tp_str consider that a type's tp_str
6629 could do something that could lead to an inifinite recursion.
6630 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6631 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006632
Georg Brandl3ee81df2008-05-17 18:14:43 +00006633- Issue #1164: It was possible to trigger deadlock when using the
6634 'print' statement to write to a file since the GIL was not released
6635 as needed. Now PyObject_Print() does the right thing along with
6636 various tp_print implementations of the built-in types and those in
6637 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006638
Georg Brandl3ee81df2008-05-17 18:14:43 +00006639- Issue #1147: Exceptions were directly allowing string exceptions in
6640 their throw() method even though string exceptions no longer
6641 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006642
Georg Brandl3ee81df2008-05-17 18:14:43 +00006643- Issue #1096: Prevent a segfault from getting the repr of a very
6644 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006645
Brett Cannon1e534b52007-09-07 04:18:30 +00006646- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006647 PyObject_Call() never calling back out to Python code to trigger
6648 recursion depth updates/checks. Required the creation of a static
6649 RuntimeError instance in case normalizing an exception put the
6650 recursion check value past its limit. Fixes crashers
6651 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006652
Georg Brandl3ee81df2008-05-17 18:14:43 +00006653- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006666- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006667 __*__ attributes. (Some already existed, e.g., __doc__ and
6668 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006669
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006670- Add -3 option to the interpreter to warn about features that are
6671 deprecated and will be changed/removed in Python 3.0.
6672
Georg Brandl2134e752007-05-21 20:34:16 +00006673- Patch #1686487: you can now pass any mapping after '**' in function
6674 calls.
6675
Collin Winter62903052007-05-18 23:11:24 +00006676- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006677 "except E as target:". This is to provide forwards compatibility
6678 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00006680- Deprecate BaseException.message as per PEP 352.
6681
Georg Brandl3ee81df2008-05-17 18:14:43 +00006682- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006683 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006685- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006686 setting a plain string, ie don't expand to single letter identifiers.
6687
Raymond Hettinger13936692007-04-11 18:40:58 +00006688- Request #1191699: Slices can now be pickled.
6689
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006690- Request #1193128: str.translate() now allows a None argument for
6691 translations that only remove characters without re-mapping the
6692 remaining characters.
6693
Georg Brandl5cb76c12007-03-21 09:00:39 +00006694- Patch #1682205: a TypeError while unpacking an iterable is no longer
6695 masked by a generic one with the message "unpack non-sequence".
6696
Neal Norwitzaa754b72007-03-21 06:39:48 +00006697- Remove unused file Python/fmod.c.
6698
Guido van Rossum143b5642007-03-23 04:58:42 +00006699- Bug #1683368: The object.__init__() and object.__new__() methods are
6700 now stricter in rejecting excess arguments. The only time when
6701 either allows excess arguments is when it is not overridden and the
6702 other one is. For backwards compatibility, when both are
6703 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006704 warning later). Also, type.__init__() insists on the same signature
6705 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006706
Georg Brandl3ee81df2008-05-17 18:14:43 +00006707- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6708 object to complex using its __complex__() method before falling back
6709 to the __float__() method. Therefore, the functions in the cmath
6710 module now can operate on objects that define a __complex__()
6711 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007785 time so that opening a database previously created with the DB_DUP
7786 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7787 opens. Specifically: dictionary assignment to a DB object will
7788 replace all values for a given key when the database allows
7789 duplicate values. DB users should use DB.put(k, v) when they want
7790 to store duplicates; not DB[k] = v.

7797 characters with ASCII value less than 32. Also, it correctly quotes
7798 dots only if they occur on a single line, as opposed to the previous
7799 behavior of quoting dots if they are the second character of any
7800 line.
