Nadeem Vawda252f4dc2012-11-11 02:14:15 +01001442 to the last call. decompressobj().flush() now correctly sets unused_data and
1443 unconsumed_tail. A bug in the handling of MemoryError when setting the
1444 unconsumed_tail attribute has also been fixed. Patch by Serhiy Storchaka.

Ned Deily18fae3f2013-01-31 01:24:55 -08001766- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1767 In particular, fix extension module build failures when trying to use
1768 32-bit-only installer Pythons on systems with Xcode 4 (currently
1769 OS X 10.8, 10.7, and optionally 10.6).
1770 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1771 * Since Xcode 4 removes ppc support, extension module builds now
1772 check for ppc compiler support and by default remove ppc and
1773 ppc64 archs when they are not available.
1774 * Extension module builds now revert to using system installed
1775 headers and libs (/usr and /System/Library) if the SDK used
1776 to build the interpreter is not installed or has moved.
1777 * Try to avoid building extension modules with deprecated
1778 and problematic Apple llvm-gcc compiler. If original compiler
1779 is not available, use clang instead by default.

2134 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01002204 has left two versions of customize_compiler, the original in
2205 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002210- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2211 Distutils-based packages with C extension modules may fail because
2212 Apple has removed gcc-4.2, the version used to build python.org
2213 64-bit/32-bit Pythons. If the user does not explicitly override
2214 the default C compiler by setting the CC environment variable,
2215 Distutils will now attempt to compile extension modules with clang
2216 if gcc-4.2 is required but not found. Also as a convenience, if
2217 the user does explicitly set CC, substitute its value as the default
2218 compiler in the Distutils LDSHARED configuration variable for OS X.
2219 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2220 SDK, neither of which are available in Xcode 4. This change does not
2221 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002471- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2472 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2473 interpreter process. This could cause failures in non-Distutils subprocesses
2474 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002475 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002476 deployment target only in the environment of each build subprocess. It is
2477 still possible to globally override the default by setting
2478 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2479 greater or equal to the default value, the value with which the interpreter
2480 was built.

2510 the ticker doesn't have to wind down to zero from the old starting point
2511 before the new interval takes effect. And if the user increases the
2512 interval, it makes sure the new limit takes effect right away rather have an
2513 early task switch before recognizing the new interval.

Antoine Pitrouf7f390a2010-09-14 14:37:18 +00003479- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
3480 SSLSocket.sendto() to match the corresponding socket methods. Also,
3481 fix various SSLSocket methods to raise socket.error rather than an
3482 unhelpful TypeError when called on an unconnected socket. Original patch
3483 by Andrew Bennetts.

3492
Raymond Hettinger20397532010-09-12 02:11:45 +00003493- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3494 This prevents user-created self-referencing ordered dictionaries from
3495 becoming permanently uncollectable GC garbage. The downside is that
3496 removing __del__ means that the internal doubly-linked list has to wait for
3497 GC collection rather than freeing memory immediately when the refcnt drops
3498 to zero.
3499

3503
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003504- Issue #9792: In case of connection failure, socket.create_connection()
3505 would swallow the exception and raise a new one, making it impossible
3506 to fetch the original errno, or to filter timeout errors. Now the
3507 original error is re-raised.

3511 be updated back after the system call. Original patch by Brian Brazil.

3528
R. David Murray7c4bf552010-08-25 01:45:57 +00003529- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3530 character years even if the message contains RFC822 two character years.
3531
Daniel Stutzbach91287322010-08-24 21:09:30 +00003532- Issue #8750: Fixed MutableSet's methods to correctly handle

3544 module now correctly return a set. (Patch by Eli Bendersky.)
3545
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003546- Issue #9617: Signals received during a low-level write operation aren't
3547 ignored by the buffered IO layer anymore.
3548
Benjamin Peterson52c36052010-08-21 03:03:22 +00003549- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3550 are not held onto after they are deleted elsewhere.
3551
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003552- Issue #9626: the view methods for collections.OrderedDict() were returning

3558 without this marker will not be overwritten or removed.
3559
Antoine Pitroue1436d12010-08-12 15:25:51 +00003560- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3561 and a BadZipfile error is raised if it doesn't match (as used to be the
3562 case in Python 2.5 and earlier).
3563
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003564- Issue #9550: a BufferedReader could issue an additional read when the
3565 original read request had been satisfied, which could block indefinitely
3566 when the underlying raw IO channel was e.g. a socket. Report and original
3567 patch by Jason V. Miller.
3568
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003569- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00003587- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
3588 This is how it is supposed to work, wget and curl do the same. Previous
3589 behavior was wrong.

3597 the option character for the added 'h/help' option if prefix_chars
3598 does not contain a '-', instead of raising an error.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003956- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

3959 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3960 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

3972 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004317 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4318 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4319 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4340-----------------
4341
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004342- Issue #7301: Add environment variable $PYTHONWARNINGS.
4343
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004344- Issue #8329: Don't return the same lists from select.select when no fds are
4345 changed.
4346
Georg Brandlfee0f442010-05-22 21:26:21 +00004347- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004348 on 64-bit machines. The shift count for either left or right shift is
4349 permitted to be up to sys.maxsize.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004355- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4356
Georg Brandlfee0f442010-05-22 21:26:21 +00004357- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4358 with a non-empty format string. This is an effort to future-proof user
4359 code. If a derived class does not currently implement __format__ but later
4360 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004361 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004362 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004363

Victor Stinner66644262010-03-10 22:30:19 +00004377- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004378 (SIGINT). If an error occurs while importing the site module, the error is

4394
Georg Brandlfee0f442010-05-22 21:26:21 +00004395- Issue #8257: The Decimal construct now accepts a float instance directly,
4396 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004397
4398 >>> Decimal(1.1)
4399 Decimal('1.100000000000000088817841970012523233890533447265625')
4400
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004401- collections.Counter() now supports a subtract() method.
4402
Georg Brandlfee0f442010-05-22 21:26:21 +00004403- The functools module now has a total_ordering() class decorator to simplify
4404 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004406- The functools module also adds cmp_to_key() as a tool to transition old-style
4407 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004408
Georg Brandlfee0f442010-05-22 21:26:21 +00004409- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4410 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004411
Georg Brandlfee0f442010-05-22 21:26:21 +00004412- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4413 InvalidOperation instead of returning False. (Comparisons involving a quiet
4414 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4415 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004416
Georg Brandlfee0f442010-05-22 21:26:21 +00004417- Issue #2531: Comparison operations between floats and Decimal instances now
4418 return a result based on the numeric values of the operands; previously they
4419 returned an arbitrary result based on the relative ordering of id(float) and
4420 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004421
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004422- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004423 argument `-` which tells it to read files to compile from stdin. Each line is
4424 read on demand and the named file is compiled immediately. (Original patch by
4425 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00004430- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4431 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004432 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004433
Georg Brandlfee0f442010-05-22 21:26:21 +00004434- Comparisons using one of <, <=, >, >= between a complex instance and a
4435 Fractions instance now raise TypeError instead of returning True/False. This
4436 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4437 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004438

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004536- Issue #8300: When passing a non-integer argument to struct.pack with any
4537 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00004541- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4542 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4543 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004544 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4545 inconsistent: __int__ was used for some integer codes but not for others, and
4546 the set of integer codes for which it was used differed between native packing
4547 and standard packing.)

4779 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004780 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00004799- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4800 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4801 returning NULL. The macro now returns a statically allocated empty string
4802 instead.

4812 strings,
4813 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long

Georg Brandlba83f822010-03-14 09:50:54 +00004848 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004854- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004855 file position when calling `truncate()`. It would previously change the file
4856 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004857 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4858
Georg Brandlba83f822010-03-14 09:50:54 +00004859- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4860 class used to represent files stored inside an archive. The new
4861 implementation is significantly faster and can be wrapped in a
4862 ``io.BufferedReader`` object for more speedups. It also solves an issue
4863 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4864 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004874- Issue #7748: Since unicode values are supported for some metadata options in
4875 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4876 encoded string for them. This ensures that the upload and register commands
4877 send the correct values to PyPI without any error.

4962 These functions and methods now raise TypeError instead. The majority of the
4963 effects of this change are in the extension modules, but some core functions
4964 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4965 and many unicode/str methods.

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005132

Georg Brandlba83f822010-03-14 09:50:54 +00005147- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5148 decimal string that's guaranteed to round back to x under correct rounding
5149 (with round-half-to-even rounding mode). Previously it gave a string based on
5150 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5151 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5152 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005153
Georg Brandlba83f822010-03-14 09:50:54 +00005154- Issue #7117: On almost all platforms: float-to-string and string-to-float
5155 conversions within Python are now correctly rounded. Places these conversions
5156 occur include: str for floats and complex numbers; the float and complex
5157 constructors; old-style and new-style numeric formatting; serialization and
5158 deserialization of floats and complex numbers using marshal, pickle and json;
5159 parsing of float and imaginary literals in Python code; Decimal-to-float
5160 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005161
Georg Brandlba83f822010-03-14 09:50:54 +00005162 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5163 providing correctly-rounded strtod and dtoa C functions. This code is
5164 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5165 the C compiler. There may be a small number of platforms on which correct
5166 operation of this code cannot be guaranteed, so the code is not used: notably,
5167 this applies to platforms where the C double format is not IEEE 754 binary64,
5168 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5169 and Python's configure script is unable to determine how to change the FPU
5170 precision. On these platforms conversions use the platform strtod and dtoa,
5171 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005172
Georg Brandlba83f822010-03-14 09:50:54 +00005173- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5174 uses the correctly-rounded string <-> float conversions described above (when
5175 available), and so produces correctly rounded results that will display nicely
5176 under the float repr. There are two related small changes: (1) round now
5177 accepts any class with an ``__index__()`` method for its second argument (but
5178 no longer accepts floats for the second argument), and (2) an excessively
5179 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5180 raises an exception.

5329 but with at least one decimal point and with a default precision
5330 of 12. Previously, the behavior the same but with a default precision of 6.
5331 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00005473- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5474 existing .py counterpart, override the co_filename attributes of all code

Georg Brandlba83f822010-03-14 09:50:54 +00005531- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5532 file objects with closefd=False. The file descriptor is still kept open but
5533 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00005557- On windows, ``os.chdir()`` given unicode was not working if

5559 this code path is really executed because I cannot move to such directory on
5560 win2k)

Walter Dörwalded960ac2009-05-03 22:36:33 +00005585- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5586 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5587 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5588 of using the replace error handler in PyUnicode_DecodeUTF8().
5589
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005590- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00005593- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5595 gives improved memory leak detection when running under Valgrind, while taking
5596 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00006843 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006966- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6967 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6968 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6969 ``printf`` function, whereas PyString_FromFormat has an independent
6970 implementation and uses "%zd" on all platforms for size_t values.
6971 This makes a difference on win64, where ``printf`` needs "%Id" to display
6972 64bit values.

6978 object; previously an int would be returned for small values. the __long__
6979 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitrou0668c622008-08-26 22:42:08 +00006992 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6993 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6995 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6996 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007135What's New in Python 2.6 beta 3?
7136================================
7137
Barry Warsaw07a4a382008-08-21 01:15:08 +00007138*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007139
7140Core and Builtins
7141-----------------
7142
Guido van Rossumf8402962008-08-20 15:01:50 +00007143- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7144 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7145 extensions do not automatically benefit from the class attribute
7146 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7147 to their tp_flags field if they care. This is a backwards
7148 compatibility feature; in 3.0, all types will use the cache by
7149 default.
7150
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007151- Keyword arguments can now follow starred arguments. (``f(a, *args,
7152 keyword=23)`` is now valid syntax.)
7153
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007154- ctypes function pointers that are COM methods have a boolean True
7155 value again.
7156
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007157- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7158 by denying s# to parse objects that have a releasebuffer procedure,
7159 and introducing s*.
7160
Georg Brandl1e13ea92008-08-11 09:07:59 +00007161- Issue #3537: Fix an assertion failure when an empty but presized dict
7162 object was stored in the freelist.
7163
Mark Dickinsonb6467572008-08-04 21:30:09 +00007164- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7165 ValueError consistently across platforms.
7166
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007167- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7168 (64bit Unix, for example), unichr() would truncate its argument and return
7169 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7170
Neal Norwitze7d8be82008-07-31 17:17:14 +00007171- Apply security patches from Apple.
7172
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007173- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7174 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7175
Antoine Pitrou92f82162008-07-25 22:22:08 +00007176- Issue #1819: function calls with several named parameters are now on
7177 average 35% faster (as measured by pybench).
7178
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007179- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7180 the python debugger steps into a class statement: the free variables (local
7181 variables defined in an outer scope) would be deleted from the outer scope.
7182
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007183- Issue #2620: Overflow checking when allocating or reallocating memory
7184 was not always being done properly in some python types and extension
7185 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7186 all been updated to perform better checks and places in the code that
7187 would previously leak memory on the error path when such an allocation
7188 failed have been fixed.

7191-------
7192
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007193- Issue #3612: Added some missing basic types in ctypes.wintypes.
7194
Benjamin Petersone977ad42008-08-20 01:42:01 +00007195- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7196 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7197
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007198- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7199 version reported by these tools does not necessarily follow the python
7200 version numbering scheme, so the module is less strict when parsing it.
7201
Nick Coghlanf70385a2008-08-18 12:42:46 +00007202- Issue #2235: Added Py3k warnings for types which will become unhashable
7203 under the stricter __hash__ inheritance rules in 3.0. Several types
7204 which did not meet the rules for hash invariants and were already
7205 unhashable in 3.0 have now been explicitly flagged as unhashable in
7206 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7207 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7208
Brett Cannon88f801d2008-08-18 00:46:22 +00007209- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7210 imported into the module but exposed as part of the module's API.
7211
Brett Cannon7b96f072008-08-18 00:41:11 +00007212- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7213
Brett Cannon46225e72008-08-18 00:36:52 +00007214- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7215
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007216- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7217
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007218- Issue #3575: Incremental decoder's decode function now takes bytearray
7219 by using 's*' instead of 't#'.
7220
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007221- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007222 fails unicode conversion on 2nd parameter. (windows only)
7223
Georg Brandl222e2082010-08-01 22:27:39 +00007224- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007225 in a redirect.
7226
Brett Cannonabe423e2008-08-16 21:47:07 +00007227- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007228 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007229
Facundo Batistaeb90b782008-08-16 14:44:07 +00007230- Issue #2776: fixed small issue when handling an URL with double slash
7231 after a 302 response in the case of not going through a proxy.
7232
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007233- Issue #2676: in the email package, content-type parsing was hanging on
7234 pathological input because of quadratic or exponential behaviour of a
7235 regular expression.
7236
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007237- Issue #3476: binary buffered reading through the new "io" library is now
7238 thread-safe.
7239
Brett Cannonbf3157b2008-08-14 05:00:03 +00007240- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7241 since mimetools itself is deprecated. Because modules are cached, all
7242 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7243
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007244- Issue #3134: shutil referenced undefined WindowsError symbol.
7245
Robert Schuppenies14646332008-08-10 11:01:53 +00007246- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7247 menu entries were not deleted.
7248
Brett Cannon83e81842008-08-09 23:30:55 +00007249- Copied the implementation of reduce() to _functools.reduce() to have a
7250 version that did not raise a DeprecationWarning under -3.
7251
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007252- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7253 a MemoryError rather than silently stop the iteration.
7254
Guido van Rossum59ce9012008-08-09 14:55:34 +00007255- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7256 to _sre.compile() will now be rejected. This should not affect anybody
7257 since the re.compile() function never generates invalid re-bytecode.
7258
Skip Montanaroa032bf42008-08-08 22:52:51 +00007259- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7260 upon first access it can be automatically initialized from the csv file if
7261 it wasn't initialized during instantiation.
7262
Brett Cannon3aa2a492008-08-06 22:28:09 +00007263- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7264 the reload() built-in has been removed.
7265
Brett Cannon7e30b672008-08-04 21:52:25 +00007266- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007267 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7272 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007273
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007274- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7275 raised an AttributeError.
7276
Benjamin Peterson01a24322008-07-28 23:35:27 +00007277- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007278 asking for a specific length. This problem only affected files opened
7279 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007280
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007281- Issue #3449: Update decimal module to use most recent specification
7282 (v. 1.68) and tests (v. 2.58) from IBM.
7283
Georg Brandl222e2082010-08-01 22:27:39 +00007284- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007285

7288
Georg Brandlf9efabb2008-07-23 15:16:45 +00007289- Deprecate the "ast" parser function aliases.
7290
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007291- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7292
7293- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7294 invalid arguments.
7295
7296- Issue #3302: Fix several crashes when calling locale's gettext functions
7297 with None arguments.
7298
7299- Issue #3389: Allow resolving dotted names for handlers in logging
7300 configuration files.
7301
7302- Deprecate the sunaudio module for removal in Python 3.0.
7303
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007304- Issue #3394: zipfile.writestr sets external attributes when passed a
7305 file name rather than a ZipInfo instance, so files are extracted with
7306 mode 0600 rather than 000 under Unix.
7307
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007308- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7309 argument in python 2.5, this broke code that subclassed Popen to include its
7310 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007320- Issue #2235: the C API function PyObject_HashNotImplemented and its
7321 interaction with the tp_hash slot (added in 2.6b2) are now documented
7322
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007323- Issue #643841: The language reference now provides more detailed
7324 coverage of the lookup process for special methods. The disclaimers
7325 regarding lack of coverage of new-style classes have also been
7326 removed, since the coverage is now fairly reasonable.

7335-----------------
7336
Georg Brandl3e483f62008-07-16 22:57:41 +00007337- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7338 its methods now allow for items objects that can be converted to
7339 an integer using operator.index().
7340
Mark Dickinson64b7e502008-07-16 09:40:03 +00007341- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7342 produced a ValueError instead of giving the correct float.
7343
Eric Smitha5fa5a22008-07-16 00:11:49 +00007344- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7345 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7346
Mark Dickinson7103aa42008-07-15 19:08:33 +00007347- Issue #3008: the float type has a new instance method 'float.hex'
7348 and a new class method 'float.fromhex' to convert floating-point
7349 numbers to and from hexadecimal strings, respectively.
7350
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007351- Issue #2235: __hash__ is once again inherited by default. To allow
7352 collections.Hashable to remain meaningful in the presence of the
7353 default hash implementation (object.__hash__), it is now possible
7354 to explicit block inheritance of hash by setting __hash__=None at
7355 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7356 level.
7357
Nick Coghlanb028f502008-07-13 14:52:36 +00007358- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7359 the parent module cannot be found while performing an absolute import.
7360 This means that an incorrectly defined __package__ attribute will
7361 now only prevent relative imports in that module rather than causing
7362 all imports from that module to fail.
7363
Nick Coghlan14ff9942008-07-08 14:21:42 +00007364- Issue #2517: Allow unicode messages in Exceptions again by correctly
7365 bypassing the instance dictionary when looking up __unicode__ on
7366 new-style classes.
7367
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007368- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7369 set to a custom object whose write() method happens to install
7370 another file in sys.stdout.

7374 another thread's dictionary.
7375
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007376- Issue #3004: Minor change to slice.indices(): the start and stop
7377 arguments are now treated identically, making the behaviour easier
7378 to describe and understand. For example, slice(None, -10,
7379 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7380 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7381 10, -1).
7382
Georg Brandl278fc502008-07-19 12:46:12 +00007383- Issue #3219: Calling a function with repeated keyword arguments,
7384 f(a=2, a=23), would not cause a syntax error. This was a regression
7385 from 2.4 caused by the switch to the new compiler.

7832 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007833 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007834
7835 This is controlled by the configure argument ``--with-universal-archs``:
7836
7837 - ``--with-universal-archs=all``: install 4-way universal
7838
7839 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7840
7841 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7842
7843 This option should be used in combination with ``--enable-universalsdk=``.
7844
7845 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007894- Issue #1631171: Re-implement the 'warnings' module in C (the
7895 original Python code has been kept as backup). This will allow for
7896 using the 'warning's machinery in such places as the parser where
7897 use of pure Python code is not possible. Both the ``showarning()``
7898 and ``formatwarning()`` gain an optional 'line' argument which is
7899 not called by default for backwards-compatibility reasons. Setting
7900 ``warnings.showwarning()`` to an implementation that lacks support
7901 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007926- The getpass module has been improved on Unix. It now uses /dev/tty
7927 by default and uses stderr instead of stdout. A GetPassWarning is
7928 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007956- Issue #2385: distutils.core.run_script() makes __file__ available,
7957 so the controlled environment will more closely mirror the typical
7958 script environment. This supports setup.py scripts that refer to
7959 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007964- Issue #2550: The approach used by client/server code for obtaining
7965 ports to listen on in network-oriented tests has been refined in an
7966 effort to facilitate running multiple instances of the entire
7967 regression test suite in parallel without issue.
7968 test_support.bind_port() has been fixed such that it will always
7969 return a unique port -- which wasn't always the case with the
7970 previous implementation, especially if socket options had been set
7971 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7972 new implementation of bind_port() will actually raise an exception
7973 if it is passed an AF_INET/SOCK_STREAM socket with either the
7974 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7975 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7976 the socket it's been passed. This currently only applies to
7977 Windows. This option prevents any other sockets from binding to the
7978 host/port we've bound to, thus removing the possibility of the
7979 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7980 when a second SOCK_STREAM socket binds and accepts to a host/port
7981 that's already been bound by another socket. The optional preferred
7982 port parameter to bind_port() has been removed. Under no
7983 circumstances should tests be hard coding ports!
7984
7985 test_support.find_unused_port() has also been introduced, which will
7986 pass a temporary socket object to bind_port() in order to obtain an
7987 unused port. The temporary socket object is then closed and
7988 deleted, and the port is returned. This method should only be used
7989 for obtaining an unused port in order to pass to an external program
7990 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7991 a parameter to a server-oriented class that doesn't give you direct
7992 access to the underlying socket used.
7993
7994 Finally, test_support.HOST has been introduced, which should be used
7995 for the host argument of any relevant socket calls (i.e. bind and
7996 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007997
7998 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007999 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008000 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8001 test_asynchat and test_socket_ssl.
8002
Georg Brandl3ee81df2008-05-17 18:14:43 +00008003 It is now possible for multiple instances of the regression test
8004 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008283- Added the future_builtins module, which contains hex() and oct().
8284 These are the PEP 3127 version of these functions, designed to be
8285 compatible with the hex() and oct() builtins from Python 3.0. They
8286 differ slightly in their output formats from the existing, unchanged
8287 Python 2.6 builtins. The expected usage of the future_builtins
8288 module is:
8289 from future_builtins import hex, oct
8290
Eric Smith7ef40bf2008-02-20 23:34:22 +00008291- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8292 exponents for exponents with absolute value < 100. Follows C99
8293 standard. This is a change on Windows, which would use 3 digits.
8294 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8295 so that any alterations it does to the resulting string will be
8296 available in stringlib/formatter.h (for float.__format__).
8297
Eric Smith5a3c1352008-02-19 13:21:56 +00008298- Implemented PEP 3101, Advanced String Formatting. This adds a new
8299 builtin format(); a format() method for str and unicode; a
8300 __format__() method to object, str, unicode, int, long, float, and
8301 datetime; the class string.Formatter; and the C API
8302 PyObject_Format().
8303
Georg Brandl3ee81df2008-05-17 18:14:43 +00008304- Fixed several potential crashes, all caused by specially crafted
8305 __del__ methods exploiting objects in temporarily inconsistent
8306 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008307
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008308- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008309 prevent a possible crash: an Abstract Base Class would try to access
8310 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008311

Georg Brandl3ee81df2008-05-17 18:14:43 +00008315- Clear all free lists during a gc.collect() of the highest generation
8316 in order to allow pymalloc to free more arenas. Python may give back
8317 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008318
Georg Brandl3ee81df2008-05-17 18:14:43 +00008319- Issue #2045: Fix an infinite recursion triggered when printing a
8320 subclass of collections.defaultdict, if its default_factory is set
8321 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008322
Christian Heimesf75dbef2008-02-08 00:11:31 +00008323- Fixed a minor memory leak in dictobject.c. The content of the free
8324 list was not freed on interpreter shutdown.
8325
Georg Brandl21e99f42010-03-07 15:23:59 +00008326- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008327 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008328
Georg Brandl3ee81df2008-05-17 18:14:43 +00008329- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8330 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008331 to compact the internal free lists of pre-allocted ints and floats.
8332
Georg Brandl3ee81df2008-05-17 18:14:43 +00008333- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8334 calls. Python expected the return type int but the fork familie
8335 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008336
Georg Brandl3ee81df2008-05-17 18:14:43 +00008337- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008349- Patch #1473257: generator objects gain a gi_code attribute. This is
8350 the same object as the func_code attribute of the function that
8351 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008352
Georg Brandl3ee81df2008-05-17 18:14:43 +00008353- Issue #1920: "while 0" statements were completely removed by the
8354 compiler, even in the presence of an "else" clause, which is
8355 supposed to be run when the condition is false. Now the compiler
8356 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008357
Guido van Rossumeead05f2008-01-24 18:21:02 +00008358- A few crashers fixed: weakref_in_del.py (issue #1377858);
8359 loosing_dict_ref.py (issue #1303614, test67.py);
8360 borrowed_ref_[34].py (not in tracker).
8361
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008362- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008363 suppressed while an extension is loaded by calling SetErrorMode in
8364 dynload_win.c. The error is still reported properly.
8365
Georg Brandl3ee81df2008-05-17 18:14:43 +00008366- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008367 several extension methods and modules do not work without unicode
8368 support.
8369
Georg Brandl26543b12008-01-21 18:36:51 +00008370- Issue #1882: when compiling code from a string, encoding cookies in the
8371 second line of code were not always recognized correctly.
8372
Georg Brandl14404b62008-01-19 19:27:05 +00008373- Issue #1679: "0x" was taken as a valid integer literal.
8374
Georg Brandl6caad7d2008-01-26 14:19:22 +00008375- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008376 added.
8377
Christian Heimesc94e2b52008-01-14 04:13:37 +00008378- sys.float_info / PyFloat_GetInfo: The floating point information
8379 object was converted from a dict to a specialized structseq object.
8380
Georg Brandl3ee81df2008-05-17 18:14:43 +00008381- Patch #1816: Added sys.flags structseq. It exposes the status of
8382 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008383
Georg Brandl3ee81df2008-05-17 18:14:43 +00008384- Objects/structseq.c: Implemented new structseq representation. The
8385 patch makes structseqs (e.g. the return value of os.stat) more
8386 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008387
Georg Brandl3ee81df2008-05-17 18:14:43 +00008388- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00008410 and INF. float("nan"), float("inf") and float("-inf") now work on
8411 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008412
Georg Brandl3ee81df2008-05-17 18:14:43 +00008413- Compiler now generates simpler and faster code for dictionary
8414 literals. The oparg for BUILD_MAP now indicates an estimated
8415 dictionary size. There is a new opcode, STORE_MAP, for adding
8416 entries to the dictionary.

Neal Norwitz44f326e2007-10-05 05:29:17 +00008458- Fix warnings found by the new version of the Coverity checker.
8459
Georg Brandl21e99f42010-03-07 15:23:59 +00008460- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008461 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8462 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008463
Georg Brandl3ee81df2008-05-17 18:14:43 +00008464- Issue #1686386: Tuple's tp_repr did not take into account the
8465 possibility of having a self-referential tuple, which is possible
8466 from C code. Nor did object's tp_str consider that a type's tp_str
8467 could do something that could lead to an inifinite recursion.
8468 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8469 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008470
Georg Brandl3ee81df2008-05-17 18:14:43 +00008471- Issue #1164: It was possible to trigger deadlock when using the
8472 'print' statement to write to a file since the GIL was not released
8473 as needed. Now PyObject_Print() does the right thing along with
8474 various tp_print implementations of the built-in types and those in
8475 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008476
Georg Brandl3ee81df2008-05-17 18:14:43 +00008477- Issue #1147: Exceptions were directly allowing string exceptions in
8478 their throw() method even though string exceptions no longer
8479 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008480
Georg Brandl3ee81df2008-05-17 18:14:43 +00008481- Issue #1096: Prevent a segfault from getting the repr of a very
8482 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008483
Brett Cannon1e534b52007-09-07 04:18:30 +00008484- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008485 PyObject_Call() never calling back out to Python code to trigger
8486 recursion depth updates/checks. Required the creation of a static
8487 RuntimeError instance in case normalizing an exception put the
8488 recursion check value past its limit. Fixes crashers
8489 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008490

Neal Norwitz0ac60192007-05-27 04:08:54 +00008504- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008505 __*__ attributes. (Some already existed, e.g., __doc__ and
8506 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008507
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008508- Add -3 option to the interpreter to warn about features that are
8509 deprecated and will be changed/removed in Python 3.0.
8510
Georg Brandl2134e752007-05-21 20:34:16 +00008511- Patch #1686487: you can now pass any mapping after '**' in function
8512 calls.
8513
Collin Winter62903052007-05-18 23:11:24 +00008514- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008515 "except E as target:". This is to provide forwards compatibility
8516 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008517
Brett Cannon229cee22007-05-05 01:34:02 +00008518- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008523- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008524 setting a plain string, ie don't expand to single letter identifiers.
8525
Raymond Hettinger13936692007-04-11 18:40:58 +00008526- Request #1191699: Slices can now be pickled.
8527
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008528- Request #1193128: str.translate() now allows a None argument for
8529 translations that only remove characters without re-mapping the
8530 remaining characters.
8531
Georg Brandl5cb76c12007-03-21 09:00:39 +00008532- Patch #1682205: a TypeError while unpacking an iterable is no longer

8536
Guido van Rossum143b5642007-03-23 04:58:42 +00008537- Bug #1683368: The object.__init__() and object.__new__() methods are
8538 now stricter in rejecting excess arguments. The only time when
8539 either allows excess arguments is when it is not overridden and the
8540 other one is. For backwards compatibility, when both are
8541 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008542 warning later). Also, type.__init__() insists on the same signature
8543 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008544
Georg Brandl3ee81df2008-05-17 18:14:43 +00008545- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8546 object to complex using its __complex__() method before falling back
8547 to the __float__() method. Therefore, the functions in the cmath
8548 module now can operate on objects that define a __complex__()
8549 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008550
Georg Brandl3ee81df2008-05-17 18:14:43 +00008551- Patch #1623563: allow __class__ assignment for classes with
8552 __slots__. The old and the new class are still required to have the
8553 same slot names.

8559 ``object.__reduce_ex__()`` is called with an object that is faking
8560 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008561
Georg Brandl3ee81df2008-05-17 18:14:43 +00008562- Patch #1680015: Don't modify __slots__ tuple if it contains an

8566
Georg Brandl7b9c5552007-03-12 14:30:05 +00008567- Bug #1678647: write a newline after printing an exception in any
8568 case, even when converting the value to a string failed.
8569
Georg Brandl871f1bc2007-03-12 13:17:36 +00008570- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008571 its argument, if it exists. If not, it will work like before. This
8572 allows customizing the output of dir() in the presence of a
8573 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008581- Patch #1491866: change the complex() constructor to allow
8582 parthensized forms. This means complex(repr(x)) now works instead of
8583 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008584
Georg Brandlaa2321b2007-03-07 00:40:28 +00008585- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008586 makes the filenames the warning module prints much more sensible
8587 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008588

Georg Brandl0fca97a2007-03-05 22:28:08 +00008600- Patch #1674228: when assigning a slice (old-style), check for the
8601 sq_ass_slice instead of the sq_slice slot.
8602
Georg Brandl3ee81df2008-05-17 18:14:43 +00008603- When printing an unraisable error, don't print exceptions. before
8604 the name. This duplicates the behavior whening normally printing
8605 exceptions.

9232 -- the failure just occurred later, with a more cumbersome
9233 exception.

Thomas Hellerd2ea4a22006-10-17 19:30:48 +00009444- ctypes callback functions only support 'fundamental' data types as
9445 result type. Raise an error when something else is used. This is a
9446 partial fix for Bug #1574584.
9447
Georg Brandl3ee81df2008-05-17 18:14:43 +00009448- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009504- The implementation of UnicodeError objects has been simplified
9505 (start and end attributes are now stored directly as Py_ssize_t
9506 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009507
Georg Brandl3ee81df2008-05-17 18:14:43 +00009508- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9509 with RFC 3207 and forgets any knowledge obtained from the server not
9510 obtained from the TLS negotiation itself. Patch contributed by Bill
9511 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009512
Georg Brandl3ee81df2008-05-17 18:14:43 +00009513- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009514 that the SMTP.starttls() caller no longer needs to call ehlo()
9515 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009516 does not claim to support starttls. Adds the
9517 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9518 Fenner.

9556
Georg Brandl3ee81df2008-05-17 18:14:43 +00009557- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00009560- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009561 works as expected. ``mmap.find`` also takes an optional ``end``

9587 contents before adding elements from the iterable. This fix brings
9588 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00009589
Georg Brandl3ee81df2008-05-17 18:14:43 +00009590- Added wide char functions to msvcrt module: getwch, getwche, putwch

9598 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9599 silently miscode subclasses of those types. Now, it raises a
9600 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009601

Georg Brandl3ee81df2008-05-17 18:14:43 +00009616 time so that opening a database previously created with the DB_DUP
9617 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9618 opens. Specifically: dictionary assignment to a DB object will
9619 replace all values for a given key when the database allows
9620 duplicate values. DB users should use DB.put(k, v) when they want
9621 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009622

9628 characters with ASCII value less than 32. Also, it correctly quotes
9629 dots only if they occur on a single line, as opposed to the previous
9630 behavior of quoting dots if they are the second character of any
9631 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009632

9959-----
9960
Georg Brandl3ee81df2008-05-17 18:14:43 +00009961- Unified naming convention for free lists and their limits. All free
9962 lists in Object/ are named ``free_list``, the counter ``numfree``
9963 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9964 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009965
Georg Brandl3ee81df2008-05-17 18:14:43 +00009966- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9967 to ``PyTuple_SetItem``, it can be used to populate a brand new
9968 frozenset; but it does not steal a reference to the added item.

9977
9978- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9979 ``PyFloat_GetInfo()`` to the float API.
9980
Georg Brandl3ee81df2008-05-17 18:14:43 +00009981- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9982 of w# format code incorrectly truncated the length to an int, even
9983 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9984 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009985
Georg Brandl3ee81df2008-05-17 18:14:43 +00009986- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

10003
10004- Fix some leftovers from the conversion from int to Py_ssize_t
10005 (relevant to strings and sequences of more than 2**31 items).
10006
10007- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10008 outside of pystate.c and should not be necessary.
10009
Georg Brandl3ee81df2008-05-17 18:14:43 +000010010- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10011 absolute imports. In earlier versions they might have used relative
10012 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010013
Georg Brandl3ee81df2008-05-17 18:14:43 +000010014- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10015 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010016
Georg Brandl3ee81df2008-05-17 18:14:43 +000010017- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010023- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10024 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10025 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10026 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010027

Georg Brandl3ee81df2008-05-17 18:14:43 +000010040- Removed the macfs module. It had been deprecated since Python 2.5.
10041 This lead to the deprecation of macostools.touched() as it relied
10042 solely on macfs and was a no-op under OS X.
