203 int.__pow__. These overflow checks were causing int.__pow__ to produce
204 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100205 compiler optimizing the check away. Also fix similar overflow checks
206 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

219 cleared by the garbage collector. This fixes a segfault when an instance
220 and its type get caught in a reference cycle, and the instance's
221 deallocator calls one of the methods on the type (e.g. when subclassing

Ned Deilyc47a4592012-02-11 20:40:24 +0100276 has left two versions of customize_compiler, the original in
277 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100282- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
283 Distutils-based packages with C extension modules may fail because
284 Apple has removed gcc-4.2, the version used to build python.org
285 64-bit/32-bit Pythons. If the user does not explicitly override
286 the default C compiler by setting the CC environment variable,
287 Distutils will now attempt to compile extension modules with clang
288 if gcc-4.2 is required but not found. Also as a convenience, if
289 the user does explicitly set CC, substitute its value as the default
290 compiler in the Distutils LDSHARED configuration variable for OS X.
291 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
292 SDK, neither of which are available in Xcode 4. This change does not
293 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700566- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
567 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
568 interpreter process. This could cause failures in non-Distutils subprocesses
569 and was unreliable since tests or user programs could modify the interpreter
570 environment after Distutils set it. Instead, have Distutils set the the
571 deployment target only in the environment of each build subprocess. It is
572 still possible to globally override the default by setting
573 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
574 greater or equal to the default value, the value with which the interpreter
575 was built.

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

1553 This prevents user-created self-referencing ordered dictionaries from
1554 becoming permanently uncollectable GC garbage. The downside is that
1555 removing __del__ means that the internal doubly-linked list has to wait for
1556 GC collection rather than freeing memory immediately when the refcnt drops
1557 to zero.

2018 of the number of bytes specified by the start byte.
2019 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Georg Brandlfee0f442010-05-22 21:26:21 +00002295- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
2296 string "python" as the *ident*. openlog() arguments are all optional and
2297 keywords.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002377 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2378 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2379 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2400-----------------
2401
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002402- Issue #7301: Add environment variable $PYTHONWARNINGS.
2403
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002404- Issue #8329: Don't return the same lists from select.select when no fds are
2405 changed.
2406
Georg Brandlfee0f442010-05-22 21:26:21 +00002407- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002408 on 64-bit machines. The shift count for either left or right shift is
2409 permitted to be up to sys.maxsize.
2410
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002411- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00002413- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002414
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002415- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2416
Georg Brandlfee0f442010-05-22 21:26:21 +00002417- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2418 with a non-empty format string. This is an effort to future-proof user
2419 code. If a derived class does not currently implement __format__ but later
2420 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002421 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002422 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002423
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002424- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002437- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002438 (SIGINT). If an error occurs while importing the site module, the error is
2439 printed and Python exits. Initialize the GIL before importing the site

2454
Georg Brandlfee0f442010-05-22 21:26:21 +00002455- Issue #8257: The Decimal construct now accepts a float instance directly,
2456 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002457
2458 >>> Decimal(1.1)

2460
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002461- collections.Counter() now supports a subtract() method.
2462
Georg Brandlfee0f442010-05-22 21:26:21 +00002463- The functools module now has a total_ordering() class decorator to simplify
2464 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00002472- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2473 InvalidOperation instead of returning False. (Comparisons involving a quiet
2474 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2475 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002476
Georg Brandlfee0f442010-05-22 21:26:21 +00002477- Issue #2531: Comparison operations between floats and Decimal instances now
2478 return a result based on the numeric values of the operands; previously they
2479 returned an arbitrary result based on the relative ordering of id(float) and
2480 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002481
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002482- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002483 argument `-` which tells it to read files to compile from stdin. Each line is
2484 read on demand and the named file is compiled immediately. (Original patch by
2485 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002490- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2491 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002492 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002493
Georg Brandlfee0f442010-05-22 21:26:21 +00002494- Comparisons using one of <, <=, >, >= between a complex instance and a
2495 Fractions instance now raise TypeError instead of returning True/False. This
2496 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2497 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002854- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2855 and add the additional members returned in an OSVERSIONINFOEX structure. The
2856 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002859- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2860 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2861 returning NULL. The macro now returns a statically allocated empty string
2862 instead.

2872 strings,
2873 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2874 numeric strings corresponding to subnormal values,
2875 (3) a memory leak for some values large enough to cause overflow, and
2876 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002907- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002908 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002914- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002915 file position when calling `truncate()`. It would previously change the file
2916 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002917 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2918
Georg Brandlba83f822010-03-14 09:50:54 +00002919- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2920 class used to represent files stored inside an archive. The new
2921 implementation is significantly faster and can be wrapped in a
2922 ``io.BufferedReader`` object for more speedups. It also solves an issue
2923 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002934- Issue #7748: Since unicode values are supported for some metadata options in
2935 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2936 encoded string for them. This ensures that the upload and register commands
2937 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00003006What's New in Python 2.7 alpha 2?
3007=================================

3012-----------------
3013
Georg Brandlba83f822010-03-14 09:50:54 +00003014- The ``__complex__()`` method is now looked up on the class of instances to
3015 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00003016
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003017- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3018 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3019
Mark Dickinson1b34d252010-01-01 17:27:30 +00003020- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003021 DeprecationWarning when passed a float argument where an integer was expected.
3022 These functions and methods now raise TypeError instead. The majority of the
3023 effects of this change are in the extension modules, but some core functions
3024 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3025 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00003026

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00003035- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
3036 used to drop the time part of the result.
3037
Georg Brandlba83f822010-03-14 09:50:54 +00003038- Issue #1811: Improve accuracy and cross-platform consistency for true division
3039 of integers: the result of a/b is now correctly rounded for ints a and b (at
3040 least on IEEE 754 platforms), and in particular does not depend on the
3041 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003042
Georg Brandlba83f822010-03-14 09:50:54 +00003043- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
3044 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
3045 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00003046

Ronald Oussoren92919a62009-12-24 13:30:58 +00003048 executables on OSX.
3049
Georg Brandlba83f822010-03-14 09:50:54 +00003050 These executables now work properly with the arch(1) command: ``arch -ppc
3051 python`` will start a universal binary version of python in PPC mode (unlike
3052 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00003053
Georg Brandlba83f822010-03-14 09:50:54 +00003054- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
3055 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00003056

Georg Brandlba83f822010-03-14 09:50:54 +00003066- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
3067 allowing for a maximum number of tasks within the pool to be completed by the
3068 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00003074- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00003075 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
3076 alternative to cPickle if you care about performance. Patch by Florent

Benjamin Petersonddd392c2009-12-13 19:19:07 +00003111- Issue #7349: Make methods of file objects in the io module accept None as an
3112 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
3113 the same as passing no argument.
3114
Georg Brandlba83f822010-03-14 09:50:54 +00003115- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Mark Dickinsona36507c2010-01-30 10:08:33 +00003136
Georg Brandlba83f822010-03-14 09:50:54 +00003137- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
3138 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
3139 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept

Georg Brandlba83f822010-03-14 09:50:54 +00003208- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3209 decimal string that's guaranteed to round back to x under correct rounding
3210 (with round-half-to-even rounding mode). Previously it gave a string based on
3211 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3212 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3213 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003214
Georg Brandlba83f822010-03-14 09:50:54 +00003215- Issue #7117: On almost all platforms: float-to-string and string-to-float
3216 conversions within Python are now correctly rounded. Places these conversions
3217 occur include: str for floats and complex numbers; the float and complex
3218 constructors; old-style and new-style numeric formatting; serialization and
3219 deserialization of floats and complex numbers using marshal, pickle and json;
3220 parsing of float and imaginary literals in Python code; Decimal-to-float
3221 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003222
Georg Brandlba83f822010-03-14 09:50:54 +00003223 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3224 providing correctly-rounded strtod and dtoa C functions. This code is
3225 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3226 the C compiler. There may be a small number of platforms on which correct
3227 operation of this code cannot be guaranteed, so the code is not used: notably,
3228 this applies to platforms where the C double format is not IEEE 754 binary64,
3229 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3230 and Python's configure script is unable to determine how to change the FPU
3231 precision. On these platforms conversions use the platform strtod and dtoa,
3232 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003233
Georg Brandlba83f822010-03-14 09:50:54 +00003234- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3235 uses the correctly-rounded string <-> float conversions described above (when
3236 available), and so produces correctly rounded results that will display nicely
3237 under the float repr. There are two related small changes: (1) round now
3238 accepts any class with an ``__index__()`` method for its second argument (but
3239 no longer accepts floats for the second argument), and (2) an excessively
3240 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

3468 internal representation of integers, for performance reasons. Base 2**30 is
3469 enabled by default on 64-bit machines. Add --enable-big-digits option to
3470 configure, which overrides the default. Add sys.long_info structseq to
3471 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00003534- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3535 existing .py counterpart, override the co_filename attributes of all code

3591
Georg Brandlba83f822010-03-14 09:50:54 +00003592- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3593 file objects with closefd=False. The file descriptor is still kept open but
3594 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00003618- On windows, ``os.chdir()`` given unicode was not working if
3619 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3620 this code path is really executed because I cannot move to such directory on
3621 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003623- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3624 element is temporarily replaced with an equivalent frozenset. But the
3625 eventual KeyError would always report the empty ``frozenset()`` as the missing

3647 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005024- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5025 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5026 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5027 ``printf`` function, whereas PyString_FromFormat has an independent
5028 implementation and uses "%zd" on all platforms for size_t values.
5029 This makes a difference on win64, where ``printf`` needs "%Id" to display
5030 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00005050 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

Brett Cannon1eaf0742008-09-02 01:25:16 +00005125 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5126 for catch_warnings() also led to an improvement in the raising of a
5127 DeprecationWarning related to warnings.warn_explicit().
5128
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005129- The deprecation warnings for the old camelCase threading API were removed.

5151
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005152- Issue #2975: When compiling several extension modules with Visual Studio 2008
5153 from the same python interpreter, some environment variables would grow
5154 without limit.
5155
Benjamin Peterson37346b22008-08-23 20:27:43 +00005156- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5157 exploitation of poor argument checking.
5158
Gerhard Häringef2276b2008-09-12 13:54:06 +00005159- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005193What's New in Python 2.6 beta 3?
5194================================
5195
Barry Warsaw07a4a382008-08-21 01:15:08 +00005196*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005197
5198Core and Builtins
5199-----------------
5200
Guido van Rossumf8402962008-08-20 15:01:50 +00005201- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5202 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5203 extensions do not automatically benefit from the class attribute
5204 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5205 to their tp_flags field if they care. This is a backwards
5206 compatibility feature; in 3.0, all types will use the cache by
5207 default.
5208
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005209- Keyword arguments can now follow starred arguments. (``f(a, *args,
5210 keyword=23)`` is now valid syntax.)
5211
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005212- ctypes function pointers that are COM methods have a boolean True
5213 value again.
5214
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005215- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5216 by denying s# to parse objects that have a releasebuffer procedure,
5217 and introducing s*.
5218
Georg Brandl1e13ea92008-08-11 09:07:59 +00005219- Issue #3537: Fix an assertion failure when an empty but presized dict
5220 object was stored in the freelist.
5221
Mark Dickinsonb6467572008-08-04 21:30:09 +00005222- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5223 ValueError consistently across platforms.
5224
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005225- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5226 (64bit Unix, for example), unichr() would truncate its argument and return
5227 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5228
Neal Norwitze7d8be82008-07-31 17:17:14 +00005229- Apply security patches from Apple.
5230
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005231- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5232 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5233
Antoine Pitrou92f82162008-07-25 22:22:08 +00005234- Issue #1819: function calls with several named parameters are now on
5235 average 35% faster (as measured by pybench).
5236
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005237- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5238 the python debugger steps into a class statement: the free variables (local
5239 variables defined in an outer scope) would be deleted from the outer scope.
5240
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005241- Issue #2620: Overflow checking when allocating or reallocating memory
5242 was not always being done properly in some python types and extension
5243 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5244 all been updated to perform better checks and places in the code that
5245 would previously leak memory on the error path when such an allocation
5246 failed have been fixed.
5247
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005248Library
5249-------
5250
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005251- Issue #3612: Added some missing basic types in ctypes.wintypes.
5252
Benjamin Petersone977ad42008-08-20 01:42:01 +00005253- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5254 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5255
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005256- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5257 version reported by these tools does not necessarily follow the python
5258 version numbering scheme, so the module is less strict when parsing it.
5259
Nick Coghlanf70385a2008-08-18 12:42:46 +00005260- Issue #2235: Added Py3k warnings for types which will become unhashable
5261 under the stricter __hash__ inheritance rules in 3.0. Several types
5262 which did not meet the rules for hash invariants and were already
5263 unhashable in 3.0 have now been explicitly flagged as unhashable in
5264 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5265 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5266
Brett Cannon88f801d2008-08-18 00:46:22 +00005267- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5268 imported into the module but exposed as part of the module's API.
5269
Brett Cannon7b96f072008-08-18 00:41:11 +00005270- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5271
Brett Cannon46225e72008-08-18 00:36:52 +00005272- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005274- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5275
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005276- Issue #3575: Incremental decoder's decode function now takes bytearray
5277 by using 's*' instead of 't#'.
5278
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005279- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005280 fails unicode conversion on 2nd parameter. (windows only)
5281
Georg Brandl222e2082010-08-01 22:27:39 +00005282- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005283 in a redirect.
5284
Brett Cannonabe423e2008-08-16 21:47:07 +00005285- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005286 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005287
Facundo Batistaeb90b782008-08-16 14:44:07 +00005288- Issue #2776: fixed small issue when handling an URL with double slash
5289 after a 302 response in the case of not going through a proxy.
5290
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005291- Issue #2676: in the email package, content-type parsing was hanging on
5292 pathological input because of quadratic or exponential behaviour of a
5293 regular expression.
5294
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005295- Issue #3476: binary buffered reading through the new "io" library is now
5296 thread-safe.
5297
Brett Cannonbf3157b2008-08-14 05:00:03 +00005298- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5299 since mimetools itself is deprecated. Because modules are cached, all
5300 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5301
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005302- Issue #3134: shutil referenced undefined WindowsError symbol.
5303
Robert Schuppenies14646332008-08-10 11:01:53 +00005304- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5305 menu entries were not deleted.
5306
Brett Cannon83e81842008-08-09 23:30:55 +00005307- Copied the implementation of reduce() to _functools.reduce() to have a
5308 version that did not raise a DeprecationWarning under -3.
5309
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005310- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5311 a MemoryError rather than silently stop the iteration.
5312
Guido van Rossum59ce9012008-08-09 14:55:34 +00005313- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5314 to _sre.compile() will now be rejected. This should not affect anybody
5315 since the re.compile() function never generates invalid re-bytecode.
5316
Skip Montanaroa032bf42008-08-08 22:52:51 +00005317- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5318 upon first access it can be automatically initialized from the csv file if
5319 it wasn't initialized during instantiation.
5320
Brett Cannon3aa2a492008-08-06 22:28:09 +00005321- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5322 the reload() built-in has been removed.
5323
Brett Cannon7e30b672008-08-04 21:52:25 +00005324- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005325 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005336 asking for a specific length. This problem only affected files opened
5337 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005338

5364 mode 0600 rather than 000 under Unix.
5365

5383 regarding lack of coverage of new-style classes have also been
5384 removed, since the coverage is now fairly reasonable.

5393-----------------
5394
Georg Brandl3e483f62008-07-16 22:57:41 +00005395- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5396 its methods now allow for items objects that can be converted to
5397 an integer using operator.index().
5398
Mark Dickinson64b7e502008-07-16 09:40:03 +00005399- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5400 produced a ValueError instead of giving the correct float.
5401
Eric Smitha5fa5a22008-07-16 00:11:49 +00005402- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5403 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5404
Mark Dickinson7103aa42008-07-15 19:08:33 +00005405- Issue #3008: the float type has a new instance method 'float.hex'
5406 and a new class method 'float.fromhex' to convert floating-point
5407 numbers to and from hexadecimal strings, respectively.
5408
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005409- Issue #2235: __hash__ is once again inherited by default. To allow
5410 collections.Hashable to remain meaningful in the presence of the
5411 default hash implementation (object.__hash__), it is now possible
5412 to explicit block inheritance of hash by setting __hash__=None at
5413 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5414 level.
5415
Nick Coghlanb028f502008-07-13 14:52:36 +00005416- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5417 the parent module cannot be found while performing an absolute import.
5418 This means that an incorrectly defined __package__ attribute will
5419 now only prevent relative imports in that module rather than causing
5420 all imports from that module to fail.
5421
Nick Coghlan14ff9942008-07-08 14:21:42 +00005422- Issue #2517: Allow unicode messages in Exceptions again by correctly
5423 bypassing the instance dictionary when looking up __unicode__ on
5424 new-style classes.
5425
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005426- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5427 set to a custom object whose write() method happens to install
5428 another file in sys.stdout.
5429
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005430- Issue #3088: Corrected a race condition in classes derived from
5431 threading.local: the first member set by a thread could be saved in
5432 another thread's dictionary.
5433
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005434- Issue #3004: Minor change to slice.indices(): the start and stop
5435 arguments are now treated identically, making the behaviour easier
5436 to describe and understand. For example, slice(None, -10,
5437 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5438 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5439 10, -1).
5440
Georg Brandl278fc502008-07-19 12:46:12 +00005441- Issue #3219: Calling a function with repeated keyword arguments,
5442 f(a=2, a=23), would not cause a syntax error. This was a regression
5443 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005444
Georg Brandl278fc502008-07-19 12:46:12 +00005445- Issue #2862: Make int and float freelist management consistent with
5446 other freelists. Changes their CompactFreeList apis into
5447 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005448

5450-------
5451
Thomas Heller57adf222008-08-14 19:10:48 +00005452- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5453 api functions without holding the GIL, which could lead to a fatal
5454 error when they failed.
5455
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005456- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
5457

Jesse Noller13e9d582008-07-16 14:32:36 +00005464- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5465 ForkingPickler.register() to resolve conflict with ctypes.
5466
Vinay Sajip51e65192008-07-18 09:01:10 +00005467- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005468
Thomas Heller880f5292008-07-15 19:39:38 +00005469- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5470 a valid dlerror() message.
5471
Thomas Heller2bad6572008-07-15 17:19:50 +00005472- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5473 incomplete structure was created.
5474
Brett Cannon3d0b9f02008-07-13 01:15:07 +00005475- Issue #3339: dummy_thread.acquire() should not return None.
5476
Raymond Hettingerb01713e2008-07-10 14:34:57 +00005477- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
5478
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005479- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005480
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005481- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5482 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005483 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005484 content-length. The problem had been corrected in the 2.4 branch, but never
5485 merged into trunk.
5486
Georg Brandle78fbcc2008-07-05 10:13:36 +00005487- Issue #2663: add filtering capability to shutil.copytree().

5490
5491- Issue #1526: Allow more than 64k files to be added to Zip64 file.
5492
5493- Issue #1746: Correct handling of zipfile archive comments (previously
5494 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00005495 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00005496
Vinay Sajip51e65192008-07-18 09:01:10 +00005497- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005498 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005499
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005500- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5501 handling is now the same as that of other special attributes like __name__).
5502
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005503- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5504 removal in Python 3.0 in favor of urllib2.urlopen().

5514 redundant ":443" port number designation when the connection is using the
5515 default https port (443).
5516
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00005517- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl3ee81df2008-05-17 18:14:43 +00005955- Issue #1631171: Re-implement the 'warnings' module in C (the
5956 original Python code has been kept as backup). This will allow for
5957 using the 'warning's machinery in such places as the parser where
5958 use of pure Python code is not possible. Both the ``showarning()``
5959 and ``formatwarning()`` gain an optional 'line' argument which is
5960 not called by default for backwards-compatibility reasons. Setting
5961 ``warnings.showwarning()`` to an implementation that lacks support
5962 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006025- Issue #2550: The approach used by client/server code for obtaining
6026 ports to listen on in network-oriented tests has been refined in an
6027 effort to facilitate running multiple instances of the entire
6028 regression test suite in parallel without issue.
6029 test_support.bind_port() has been fixed such that it will always
6030 return a unique port -- which wasn't always the case with the
6031 previous implementation, especially if socket options had been set
6032 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6033 new implementation of bind_port() will actually raise an exception
6034 if it is passed an AF_INET/SOCK_STREAM socket with either the
6035 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6036 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6037 the socket it's been passed. This currently only applies to
6038 Windows. This option prevents any other sockets from binding to the
6039 host/port we've bound to, thus removing the possibility of the
6040 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6041 when a second SOCK_STREAM socket binds and accepts to a host/port
6042 that's already been bound by another socket. The optional preferred
6043 port parameter to bind_port() has been removed. Under no
6044 circumstances should tests be hard coding ports!
6045
6046 test_support.find_unused_port() has also been introduced, which will
6047 pass a temporary socket object to bind_port() in order to obtain an
6048 unused port. The temporary socket object is then closed and
6049 deleted, and the port is returned. This method should only be used
6050 for obtaining an unused port in order to pass to an external program
6051 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6052 a parameter to a server-oriented class that doesn't give you direct
6053 access to the underlying socket used.
6054
6055 Finally, test_support.HOST has been introduced, which should be used
6056 for the host argument of any relevant socket calls (i.e. bind and
6057 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006058
6059 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006060 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006061 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6062 test_asynchat and test_socket_ssl.
6063
Georg Brandl3ee81df2008-05-17 18:14:43 +00006064 It is now possible for multiple instances of the regression test
6065 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006344- Added the future_builtins module, which contains hex() and oct().
6345 These are the PEP 3127 version of these functions, designed to be
6346 compatible with the hex() and oct() builtins from Python 3.0. They
6347 differ slightly in their output formats from the existing, unchanged
6348 Python 2.6 builtins. The expected usage of the future_builtins
6349 module is:
6350 from future_builtins import hex, oct
6351
Eric Smith7ef40bf2008-02-20 23:34:22 +00006352- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6353 exponents for exponents with absolute value < 100. Follows C99
6354 standard. This is a change on Windows, which would use 3 digits.
6355 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6356 so that any alterations it does to the resulting string will be
6357 available in stringlib/formatter.h (for float.__format__).
6358
Eric Smith5a3c1352008-02-19 13:21:56 +00006359- Implemented PEP 3101, Advanced String Formatting. This adds a new
6360 builtin format(); a format() method for str and unicode; a
6361 __format__() method to object, str, unicode, int, long, float, and
6362 datetime; the class string.Formatter; and the C API
6363 PyObject_Format().
6364
Georg Brandl3ee81df2008-05-17 18:14:43 +00006365- Fixed several potential crashes, all caused by specially crafted
6366 __del__ methods exploiting objects in temporarily inconsistent
6367 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006368
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006369- Issue #2115: Important speedup in setting __slot__ attributes. Also

Georg Brandl3ee81df2008-05-17 18:14:43 +00006376- Clear all free lists during a gc.collect() of the highest generation
6377 in order to allow pymalloc to free more arenas. Python may give back
6378 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006379
Georg Brandl3ee81df2008-05-17 18:14:43 +00006380- Issue #2045: Fix an infinite recursion triggered when printing a
6381 subclass of collections.defaultdict, if its default_factory is set
6382 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006383
Christian Heimesf75dbef2008-02-08 00:11:31 +00006384- Fixed a minor memory leak in dictobject.c. The content of the free
6385 list was not freed on interpreter shutdown.
6386
Georg Brandl21e99f42010-03-07 15:23:59 +00006387- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006389
Georg Brandl3ee81df2008-05-17 18:14:43 +00006390- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6391 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006392 to compact the internal free lists of pre-allocted ints and floats.
6393
Georg Brandl3ee81df2008-05-17 18:14:43 +00006394- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6395 calls. Python expected the return type int but the fork familie
6396 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006397

Georg Brandl3ee81df2008-05-17 18:14:43 +00006410- Patch #1473257: generator objects gain a gi_code attribute. This is
6411 the same object as the func_code attribute of the function that
6412 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006413
Georg Brandl3ee81df2008-05-17 18:14:43 +00006414- Issue #1920: "while 0" statements were completely removed by the
6415 compiler, even in the presence of an "else" clause, which is
6416 supposed to be run when the condition is false. Now the compiler
6417 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006418
Guido van Rossumeead05f2008-01-24 18:21:02 +00006419- A few crashers fixed: weakref_in_del.py (issue #1377858);
6420 loosing_dict_ref.py (issue #1303614, test67.py);
6421 borrowed_ref_[34].py (not in tracker).
6422

6426
Georg Brandl3ee81df2008-05-17 18:14:43 +00006427- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006428 several extension methods and modules do not work without unicode
6429 support.
6430
Georg Brandl26543b12008-01-21 18:36:51 +00006431- Issue #1882: when compiling code from a string, encoding cookies in the

6433
Georg Brandl14404b62008-01-19 19:27:05 +00006434- Issue #1679: "0x" was taken as a valid integer literal.
6435
Georg Brandl6caad7d2008-01-26 14:19:22 +00006436- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006437 added.
6438
Christian Heimesc94e2b52008-01-14 04:13:37 +00006439- sys.float_info / PyFloat_GetInfo: The floating point information
6440 object was converted from a dict to a specialized structseq object.
6441
Georg Brandl3ee81df2008-05-17 18:14:43 +00006442- Patch #1816: Added sys.flags structseq. It exposes the status of
6443 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006444
Georg Brandl3ee81df2008-05-17 18:14:43 +00006445- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00006461- Improve some exception messages when Windows fails to load an
6462 extension module. Now we get for example '%1 is not a valid Win32
6463 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006471 and INF. float("nan"), float("inf") and float("-inf") now work on
6472 every platform with IEEE 754 semantics.

6476 dictionary size. There is a new opcode, STORE_MAP, for adding
6477 entries to the dictionary.

6507 file can now be directly executed by passing their name to the
6508 interpreter. The directory/zipfile is automatically inserted as the
6509 first entry in sys.path.

6520
Georg Brandl21e99f42010-03-07 15:23:59 +00006521- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006522 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6523 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006524
Georg Brandl3ee81df2008-05-17 18:14:43 +00006525- Issue #1686386: Tuple's tp_repr did not take into account the
6526 possibility of having a self-referential tuple, which is possible
6527 from C code. Nor did object's tp_str consider that a type's tp_str
6528 could do something that could lead to an inifinite recursion.
6529 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6530 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006531
Georg Brandl3ee81df2008-05-17 18:14:43 +00006532- Issue #1164: It was possible to trigger deadlock when using the
6533 'print' statement to write to a file since the GIL was not released
6534 as needed. Now PyObject_Print() does the right thing along with
6535 various tp_print implementations of the built-in types and those in
6536 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006537
Georg Brandl3ee81df2008-05-17 18:14:43 +00006538- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00006545- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006546 PyObject_Call() never calling back out to Python code to trigger
6547 recursion depth updates/checks. Required the creation of a static
6548 RuntimeError instance in case normalizing an exception put the
6549 recursion check value past its limit. Fixes crashers
6550 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006566 __*__ attributes. (Some already existed, e.g., __doc__ and
6567 __name__.)

6573 calls.
6574
Collin Winter62903052007-05-18 23:11:24 +00006575- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006576 "except E as target:". This is to provide forwards compatibility
6577 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006584- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006585 setting a plain string, ie don't expand to single letter identifiers.
6586
Raymond Hettinger13936692007-04-11 18:40:58 +00006587- Request #1191699: Slices can now be pickled.
6588
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006589- Request #1193128: str.translate() now allows a None argument for

6591 remaining characters.
6592
Georg Brandl5cb76c12007-03-21 09:00:39 +00006593- Patch #1682205: a TypeError while unpacking an iterable is no longer

6597
Guido van Rossum143b5642007-03-23 04:58:42 +00006598- Bug #1683368: The object.__init__() and object.__new__() methods are
6599 now stricter in rejecting excess arguments. The only time when
6600 either allows excess arguments is when it is not overridden and the
6601 other one is. For backwards compatibility, when both are
6602 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006603 warning later). Also, type.__init__() insists on the same signature
6604 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006605
Georg Brandl3ee81df2008-05-17 18:14:43 +00006606- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6607 object to complex using its __complex__() method before falling back
6608 to the __float__() method. Therefore, the functions in the cmath
6609 module now can operate on objects that define a __complex__()
6610 method.

6627
Georg Brandl7b9c5552007-03-12 14:30:05 +00006628- Bug #1678647: write a newline after printing an exception in any
6629 case, even when converting the value to a string failed.
6630
Georg Brandl871f1bc2007-03-12 13:17:36 +00006631- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006632 its argument, if it exists. If not, it will work like before. This
6633 allows customizing the output of dir() in the presence of a
6634 __getattr__().

6643 parthensized forms. This means complex(repr(x)) now works instead of
6644 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006645
Georg Brandlaa2321b2007-03-07 00:40:28 +00006646- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006647 makes the filenames the warning module prints much more sensible
6648 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006661- Patch #1674228: when assigning a slice (old-style), check for the
6662 sq_ass_slice instead of the sq_slice slot.
6663
Georg Brandl3ee81df2008-05-17 18:14:43 +00006664- When printing an unraisable error, don't print exceptions. before
6665 the name. This duplicates the behavior whening normally printing
6666 exceptions.

Georg Brandl92a6bae2007-03-13 17:43:32 +00007233- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007234 are set for invalid interpolation sequences that would lead to
7235 errors on reading back those values.

7291 TestCase and TestSuite subclasses (not instances) are no longer
7292 accepted in TestSuite.addTest(). This should cause no

7295 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007582 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00007584 does not claim to support starttls. Adds the
7585 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00007684 time so that opening a database previously created with the DB_DUP
7685 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7686 opens. Specifically: dictionary assignment to a DB object will
7687 replace all values for a given key when the database allows
7688 duplicate values. DB users should use DB.put(k, v) when they want
7689 to store duplicates; not DB[k] = v.

8043
Georg Brandl3ee81df2008-05-17 18:14:43 +00008044- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8045 of w# format code incorrectly truncated the length to an int, even
8046 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8047 incorrect results with huge strings.

8071 outside of pystate.c and should not be necessary.
8072
Georg Brandl3ee81df2008-05-17 18:14:43 +00008073- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8074 absolute imports. In earlier versions they might have used relative
8075 imports under some conditions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008077- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8078 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008079
