Ned Deily18fae3f2013-01-31 01:24:55 -0800959- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
960 In particular, fix extension module build failures when trying to use
961 32-bit-only installer Pythons on systems with Xcode 4 (currently
962 OS X 10.8, 10.7, and optionally 10.6).
963 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
964 * Since Xcode 4 removes ppc support, extension module builds now
965 check for ppc compiler support and by default remove ppc and
966 ppc64 archs when they are not available.
967 * Extension module builds now revert to using system installed
968 headers and libs (/usr and /System/Library) if the SDK used
969 to build the interpreter is not installed or has moved.
970 * Try to avoid building extension modules with deprecated
971 and problematic Apple llvm-gcc compiler. If original compiler
972 is not available, use clang instead by default.

1325 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001326 compiler optimizing the check away. Also fix similar overflow checks
1327 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

1341 and its type get caught in a reference cycle, and the instance's

Ned Deilyc47a4592012-02-11 20:40:24 +01001397 has left two versions of customize_compiler, the original in
1398 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001403- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1404 Distutils-based packages with C extension modules may fail because
1405 Apple has removed gcc-4.2, the version used to build python.org
1406 64-bit/32-bit Pythons. If the user does not explicitly override
1407 the default C compiler by setting the CC environment variable,
1408 Distutils will now attempt to compile extension modules with clang
1409 if gcc-4.2 is required but not found. Also as a convenience, if
1410 the user does explicitly set CC, substitute its value as the default
1411 compiler in the Distutils LDSHARED configuration variable for OS X.
1412 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1413 SDK, neither of which are available in Xcode 4. This change does not
1414 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001664- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1665 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1666 interpreter process. This could cause failures in non-Distutils subprocesses
1667 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001668 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001669 deployment target only in the environment of each build subprocess. It is
1670 still possible to globally override the default by setting
1671 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1672 greater or equal to the default value, the value with which the interpreter
1673 was built.

1702 updating the check interval, so if the user decreases the check interval,
1703 the ticker doesn't have to wind down to zero from the old starting point
1704 before the new interval takes effect. And if the user increases the
1705 interval, it makes sure the new limit takes effect right away rather have an
1706 early task switch before recognizing the new interval.

2658 and retries sending if these returned successfully, including on sockets
2659 with a timeout.

2685
Raymond Hettinger20397532010-09-12 02:11:45 +00002686- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2687 This prevents user-created self-referencing ordered dictionaries from
2688 becoming permanently uncollectable GC garbage. The downside is that
2689 removing __del__ means that the internal doubly-linked list has to wait for
2690 GC collection rather than freeing memory immediately when the refcnt drops
2691 to zero.
2692

2700 original error is re-raised.

2720 falling into recursion.
2721
R. David Murray7c4bf552010-08-25 01:45:57 +00002722- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2723 character years even if the message contains RFC822 two character years.
2724
Daniel Stutzbach91287322010-08-24 21:09:30 +00002725- Issue #8750: Fixed MutableSet's methods to correctly handle

2738
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002739- Issue #9617: Signals received during a low-level write operation aren't
2740 ignored by the buffered IO layer anymore.
2741
Benjamin Peterson52c36052010-08-21 03:03:22 +00002742- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

2744
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002745- Issue #9626: the view methods for collections.OrderedDict() were returning

2754 and a BadZipfile error is raised if it doesn't match (as used to be the
2755 case in Python 2.5 and earlier).
2756
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002757- Issue #9550: a BufferedReader could issue an additional read when the
2758 original read request had been satisfied, which could block indefinitely
2759 when the underlying raw IO channel was e.g. a socket. Report and original
2760 patch by Jason V. Miller.
2761
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002762- Issue #9551: Don't raise TypeError when setting the value to None for

2781 This is how it is supposed to work, wget and curl do the same. Previous

2791 does not contain a '-', instead of raising an error.
2792

3153 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3154 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

3166 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003511 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3512 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3513 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3534-----------------
3535
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003536- Issue #7301: Add environment variable $PYTHONWARNINGS.
3537
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003538- Issue #8329: Don't return the same lists from select.select when no fds are
3539 changed.
3540
Georg Brandlfee0f442010-05-22 21:26:21 +00003541- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003542 on 64-bit machines. The shift count for either left or right shift is
3543 permitted to be up to sys.maxsize.
3544
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003545- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00003547- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003548
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003549- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3550
Georg Brandlfee0f442010-05-22 21:26:21 +00003551- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3552 with a non-empty format string. This is an effort to future-proof user
3553 code. If a derived class does not currently implement __format__ but later
3554 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003555 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003556 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003557
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003558- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00003571- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003572 (SIGINT). If an error occurs while importing the site module, the error is

3588
Georg Brandlfee0f442010-05-22 21:26:21 +00003589- Issue #8257: The Decimal construct now accepts a float instance directly,
3590 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003591
3592 >>> Decimal(1.1)
3593 Decimal('1.100000000000000088817841970012523233890533447265625')
3594
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003595- collections.Counter() now supports a subtract() method.
3596
Georg Brandlfee0f442010-05-22 21:26:21 +00003597- The functools module now has a total_ordering() class decorator to simplify
3598 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003599
Georg Brandlfee0f442010-05-22 21:26:21 +00003600- The functools module also adds cmp_to_key() as a tool to transition old-style
3601 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003602
Georg Brandlfee0f442010-05-22 21:26:21 +00003603- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3604 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003605
Georg Brandlfee0f442010-05-22 21:26:21 +00003606- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3607 InvalidOperation instead of returning False. (Comparisons involving a quiet
3608 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3609 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003610
Georg Brandlfee0f442010-05-22 21:26:21 +00003611- Issue #2531: Comparison operations between floats and Decimal instances now
3612 return a result based on the numeric values of the operands; previously they
3613 returned an arbitrary result based on the relative ordering of id(float) and
3614 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003615
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003616- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003617 argument `-` which tells it to read files to compile from stdin. Each line is
3618 read on demand and the named file is compiled immediately. (Original patch by
3619 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00003624- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3625 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003626 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003627
Georg Brandlfee0f442010-05-22 21:26:21 +00003628- Comparisons using one of <, <=, >, >= between a complex instance and a
3629 Fractions instance now raise TypeError instead of returning True/False. This
3630 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3631 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003699- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003730- Issue #8300: When passing a non-integer argument to struct.pack with any
3731 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00003735- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3736 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3737 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003738 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3739 inconsistent: __int__ was used for some integer codes but not for others, and
3740 the set of integer codes for which it was used differed between native packing
3741 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003993- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3994 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3995 returning NULL. The macro now returns a statically allocated empty string
3996 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004042 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004048- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004049 file position when calling `truncate()`. It would previously change the file
4050 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004051 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4052
Georg Brandlba83f822010-03-14 09:50:54 +00004053- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4054 class used to represent files stored inside an archive. The new
4055 implementation is significantly faster and can be wrapped in a
4056 ``io.BufferedReader`` object for more speedups. It also solves an issue
4057 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004068- Issue #7748: Since unicode values are supported for some metadata options in
4069 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4070 encoded string for them. This ensures that the upload and register commands
4071 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004342- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4343 decimal string that's guaranteed to round back to x under correct rounding
4344 (with round-half-to-even rounding mode). Previously it gave a string based on
4345 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4346 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4347 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004348
Georg Brandlba83f822010-03-14 09:50:54 +00004349- Issue #7117: On almost all platforms: float-to-string and string-to-float
4350 conversions within Python are now correctly rounded. Places these conversions
4351 occur include: str for floats and complex numbers; the float and complex
4352 constructors; old-style and new-style numeric formatting; serialization and
4353 deserialization of floats and complex numbers using marshal, pickle and json;
4354 parsing of float and imaginary literals in Python code; Decimal-to-float
4355 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004356
Georg Brandlba83f822010-03-14 09:50:54 +00004357 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4358 providing correctly-rounded strtod and dtoa C functions. This code is
4359 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4360 the C compiler. There may be a small number of platforms on which correct
4361 operation of this code cannot be guaranteed, so the code is not used: notably,
4362 this applies to platforms where the C double format is not IEEE 754 binary64,
4363 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4364 and Python's configure script is unable to determine how to change the FPU
4365 precision. On these platforms conversions use the platform strtod and dtoa,
4366 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004368- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4369 uses the correctly-rounded string <-> float conversions described above (when
4370 available), and so produces correctly rounded results that will display nicely
4371 under the float repr. There are two related small changes: (1) round now
4372 accepts any class with an ``__index__()`` method for its second argument (but
4373 no longer accepts floats for the second argument), and (2) an excessively
4374 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4375 raises an exception.

4524 but with at least one decimal point and with a default precision
4525 of 12. Previously, the behavior the same but with a default precision of 6.
4526 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00004668- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4669 existing .py counterpart, override the co_filename attributes of all code
4670 objects if the original filename is obsolete (which can happen if the file has

4725
Georg Brandlba83f822010-03-14 09:50:54 +00004726- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4727 file objects with closefd=False. The file descriptor is still kept open but
4728 the file object behaves like a closed file. The ``FileIO`` object also got a
4729 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004749- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004752- On windows, ``os.chdir()`` given unicode was not working if
4753 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4754 this code path is really executed because I cannot move to such directory on
4755 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004757- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4758 element is temporarily replaced with an equivalent frozenset. But the
4759 eventual KeyError would always report the empty ``frozenset()`` as the missing
4760 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004780- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4781 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4782 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4783 of using the replace error handler in PyUnicode_DecodeUTF8().
4784
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004785- Issue #3739: The unicode-internal encoder now reports the number of characters

4787
Georg Brandlba83f822010-03-14 09:50:54 +00004788- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4789 allocator will be automatically disabled when running under Valgrind. This
4790 gives improved memory leak detection when running under Valgrind, while taking
4791 advantage of pymalloc at other times.

6160
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006161- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6162 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6163 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6164 ``printf`` function, whereas PyString_FromFormat has an independent
6165 implementation and uses "%zd" on all platforms for size_t values.
6166 This makes a difference on win64, where ``printf`` needs "%Id" to display
6167 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006169- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6173 object; previously an int would be returned for small values. the __long__
6174 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006184 was correctly parsed but parsing of subsequent arguments failed.
6185
Vinay Sajip35e3b032008-09-01 14:33:59 +00006186- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006187 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6188 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6189 when given a tuple of classes as second argument, were looking up
6190 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6191 type object.

6288
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006289- Issue #2975: When compiling several extension modules with Visual Studio 2008
6290 from the same python interpreter, some environment variables would grow
6291 without limit.
6292
Benjamin Peterson37346b22008-08-23 20:27:43 +00006293- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6294 exploitation of poor argument checking.

6309 wrapper for warnings.catch_warnings() that makes it easier to check
6310 that expected warning messages are being reported.
6311

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006330What's New in Python 2.6 beta 3?
6331================================
6332
Barry Warsaw07a4a382008-08-21 01:15:08 +00006333*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006334
6335Core and Builtins
6336-----------------
6337
Guido van Rossumf8402962008-08-20 15:01:50 +00006338- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6339 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6340 extensions do not automatically benefit from the class attribute
6341 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6342 to their tp_flags field if they care. This is a backwards
6343 compatibility feature; in 3.0, all types will use the cache by
6344 default.
6345
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006346- Keyword arguments can now follow starred arguments. (``f(a, *args,
6347 keyword=23)`` is now valid syntax.)
6348
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006349- ctypes function pointers that are COM methods have a boolean True
6350 value again.
6351
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006352- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6353 by denying s# to parse objects that have a releasebuffer procedure,
6354 and introducing s*.
6355
Georg Brandl1e13ea92008-08-11 09:07:59 +00006356- Issue #3537: Fix an assertion failure when an empty but presized dict
6357 object was stored in the freelist.
6358
Mark Dickinsonb6467572008-08-04 21:30:09 +00006359- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6360 ValueError consistently across platforms.
6361
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006362- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6363 (64bit Unix, for example), unichr() would truncate its argument and return
6364 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6365
Neal Norwitze7d8be82008-07-31 17:17:14 +00006366- Apply security patches from Apple.
6367
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006368- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6369 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6370
Antoine Pitrou92f82162008-07-25 22:22:08 +00006371- Issue #1819: function calls with several named parameters are now on
6372 average 35% faster (as measured by pybench).
6373
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006374- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6375 the python debugger steps into a class statement: the free variables (local
6376 variables defined in an outer scope) would be deleted from the outer scope.
6377
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006378- Issue #2620: Overflow checking when allocating or reallocating memory
6379 was not always being done properly in some python types and extension
6380 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6381 all been updated to perform better checks and places in the code that
6382 would previously leak memory on the error path when such an allocation
6383 failed have been fixed.
6384

6386-------
6387
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006388- Issue #3612: Added some missing basic types in ctypes.wintypes.
6389
Benjamin Petersone977ad42008-08-20 01:42:01 +00006390- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6391 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6392
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006393- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6394 version reported by these tools does not necessarily follow the python
6395 version numbering scheme, so the module is less strict when parsing it.
6396
Nick Coghlanf70385a2008-08-18 12:42:46 +00006397- Issue #2235: Added Py3k warnings for types which will become unhashable
6398 under the stricter __hash__ inheritance rules in 3.0. Several types
6399 which did not meet the rules for hash invariants and were already
6400 unhashable in 3.0 have now been explicitly flagged as unhashable in
6401 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6402 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6403
Brett Cannon88f801d2008-08-18 00:46:22 +00006404- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6405 imported into the module but exposed as part of the module's API.
6406
Brett Cannon7b96f072008-08-18 00:41:11 +00006407- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6408
Brett Cannon46225e72008-08-18 00:36:52 +00006409- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6410
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006411- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6412
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006413- Issue #3575: Incremental decoder's decode function now takes bytearray
6414 by using 's*' instead of 't#'.
6415
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006416- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006417 fails unicode conversion on 2nd parameter. (windows only)
6418
Georg Brandl222e2082010-08-01 22:27:39 +00006419- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006420 in a redirect.
6421
Brett Cannonabe423e2008-08-16 21:47:07 +00006422- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006423 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006424
Facundo Batistaeb90b782008-08-16 14:44:07 +00006425- Issue #2776: fixed small issue when handling an URL with double slash
6426 after a 302 response in the case of not going through a proxy.
6427
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006428- Issue #2676: in the email package, content-type parsing was hanging on
6429 pathological input because of quadratic or exponential behaviour of a
6430 regular expression.
6431
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006432- Issue #3476: binary buffered reading through the new "io" library is now
6433 thread-safe.
6434
Brett Cannonbf3157b2008-08-14 05:00:03 +00006435- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6436 since mimetools itself is deprecated. Because modules are cached, all
6437 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6438
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006439- Issue #3134: shutil referenced undefined WindowsError symbol.
6440
Robert Schuppenies14646332008-08-10 11:01:53 +00006441- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6442 menu entries were not deleted.
6443
Brett Cannon83e81842008-08-09 23:30:55 +00006444- Copied the implementation of reduce() to _functools.reduce() to have a
6445 version that did not raise a DeprecationWarning under -3.
6446
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006447- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6448 a MemoryError rather than silently stop the iteration.
6449
Guido van Rossum59ce9012008-08-09 14:55:34 +00006450- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6451 to _sre.compile() will now be rejected. This should not affect anybody
6452 since the re.compile() function never generates invalid re-bytecode.
6453
Skip Montanaroa032bf42008-08-08 22:52:51 +00006454- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6455 upon first access it can be automatically initialized from the csv file if
6456 it wasn't initialized during instantiation.
6457
Brett Cannon3aa2a492008-08-06 22:28:09 +00006458- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6459 the reload() built-in has been removed.
6460
Brett Cannon7e30b672008-08-04 21:52:25 +00006461- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006462 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6470 raised an AttributeError.
6471
Benjamin Peterson01a24322008-07-28 23:35:27 +00006472- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006473 asking for a specific length. This problem only affected files opened
6474 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006475
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006476- Issue #3449: Update decimal module to use most recent specification
6477 (v. 1.68) and tests (v. 2.58) from IBM.
6478
Georg Brandl222e2082010-08-01 22:27:39 +00006479- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

6498
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006499- Issue #3394: zipfile.writestr sets external attributes when passed a
6500 file name rather than a ZipInfo instance, so files are extracted with
6501 mode 0600 rather than 000 under Unix.
6502
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006503- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6504 argument in python 2.5, this broke code that subclassed Popen to include its
6505 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006515- Issue #2235: the C API function PyObject_HashNotImplemented and its
6516 interaction with the tp_hash slot (added in 2.6b2) are now documented
6517
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006518- Issue #643841: The language reference now provides more detailed
6519 coverage of the lookup process for special methods. The disclaimers
6520 regarding lack of coverage of new-style classes have also been
6521 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006524What's New in Python 2.6 beta 2?
6525================================
6526
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006527*Release date: 17-Jul-2008*
6528
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006529Core and Builtins
6530-----------------
6531
Georg Brandl3e483f62008-07-16 22:57:41 +00006532- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6533 its methods now allow for items objects that can be converted to
6534 an integer using operator.index().
6535
Mark Dickinson64b7e502008-07-16 09:40:03 +00006536- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6537 produced a ValueError instead of giving the correct float.
6538
Eric Smitha5fa5a22008-07-16 00:11:49 +00006539- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6540 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6541
Mark Dickinson7103aa42008-07-15 19:08:33 +00006542- Issue #3008: the float type has a new instance method 'float.hex'
6543 and a new class method 'float.fromhex' to convert floating-point
6544 numbers to and from hexadecimal strings, respectively.
6545
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006546- Issue #2235: __hash__ is once again inherited by default. To allow
6547 collections.Hashable to remain meaningful in the presence of the
6548 default hash implementation (object.__hash__), it is now possible
6549 to explicit block inheritance of hash by setting __hash__=None at
6550 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6551 level.
6552
Nick Coghlanb028f502008-07-13 14:52:36 +00006553- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6554 the parent module cannot be found while performing an absolute import.
6555 This means that an incorrectly defined __package__ attribute will
6556 now only prevent relative imports in that module rather than causing
6557 all imports from that module to fail.
6558
Nick Coghlan14ff9942008-07-08 14:21:42 +00006559- Issue #2517: Allow unicode messages in Exceptions again by correctly
6560 bypassing the instance dictionary when looking up __unicode__ on
6561 new-style classes.
6562
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006563- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

6575 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00007030 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007031
7032 This is controlled by the configure argument ``--with-universal-archs``:
7033

7035
7036 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7037
7038 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

Georg Brandl3ee81df2008-05-17 18:14:43 +00007092- Issue #1631171: Re-implement the 'warnings' module in C (the
7093 original Python code has been kept as backup). This will allow for
7094 using the 'warning's machinery in such places as the parser where
7095 use of pure Python code is not possible. Both the ``showarning()``
7096 and ``formatwarning()`` gain an optional 'line' argument which is
7097 not called by default for backwards-compatibility reasons. Setting
7098 ``warnings.showwarning()`` to an implementation that lacks support
7099 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007162- Issue #2550: The approach used by client/server code for obtaining
7163 ports to listen on in network-oriented tests has been refined in an
7164 effort to facilitate running multiple instances of the entire
7165 regression test suite in parallel without issue.
7166 test_support.bind_port() has been fixed such that it will always
7167 return a unique port -- which wasn't always the case with the
7168 previous implementation, especially if socket options had been set
7169 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7170 new implementation of bind_port() will actually raise an exception
7171 if it is passed an AF_INET/SOCK_STREAM socket with either the
7172 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7173 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7174 the socket it's been passed. This currently only applies to
7175 Windows. This option prevents any other sockets from binding to the
7176 host/port we've bound to, thus removing the possibility of the
7177 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7178 when a second SOCK_STREAM socket binds and accepts to a host/port
7179 that's already been bound by another socket. The optional preferred
7180 port parameter to bind_port() has been removed. Under no
7181 circumstances should tests be hard coding ports!
7182
7183 test_support.find_unused_port() has also been introduced, which will
7184 pass a temporary socket object to bind_port() in order to obtain an
7185 unused port. The temporary socket object is then closed and
7186 deleted, and the port is returned. This method should only be used
7187 for obtaining an unused port in order to pass to an external program
7188 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7189 a parameter to a server-oriented class that doesn't give you direct
7190 access to the underlying socket used.
7191
7192 Finally, test_support.HOST has been introduced, which should be used
7193 for the host argument of any relevant socket calls (i.e. bind and
7194 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007195
7196 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007197 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007198 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7199 test_asynchat and test_socket_ssl.
7200
Georg Brandl3ee81df2008-05-17 18:14:43 +00007201 It is now possible for multiple instances of the regression test
7202 suite to run in parallel without issue.

Facundo Batistac54aec12008-03-08 16:50:27 +00007385- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
Georg Brandl3ee81df2008-05-17 18:14:43 +00007386 optional: it defaults to the traceback of the exception that is
7387 currently being handled (is mandatory to be in the middle of an
7388 exception, otherwise it raises ValueError).

7405
Thomas Heller78b8f442008-03-05 14:53:39 +00007406- The bundled libffi copy is now in sync with the recently released
7407 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007408 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
7409 files are used. On all linux systems the --with-system-ffi
7410 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00007471- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007472 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00007474- Issue #2067: file.__exit__() now calls subclasses' close() method.
7475
7476- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007477
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007478- Issue #1881: An internal parser limit has been increased. Also see

Facundo Batistafc2d0102008-02-23 12:01:13 +00007480
Eric Smitha73fbe72008-02-23 03:09:44 +00007481- Added the future_builtins module, which contains hex() and oct().
7482 These are the PEP 3127 version of these functions, designed to be
7483 compatible with the hex() and oct() builtins from Python 3.0. They
7484 differ slightly in their output formats from the existing, unchanged
7485 Python 2.6 builtins. The expected usage of the future_builtins
7486 module is:
7487 from future_builtins import hex, oct
7488
Eric Smith7ef40bf2008-02-20 23:34:22 +00007489- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7490 exponents for exponents with absolute value < 100. Follows C99
7491 standard. This is a change on Windows, which would use 3 digits.
7492 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7493 so that any alterations it does to the resulting string will be
7494 available in stringlib/formatter.h (for float.__format__).
7495
Eric Smith5a3c1352008-02-19 13:21:56 +00007496- Implemented PEP 3101, Advanced String Formatting. This adds a new
7497 builtin format(); a format() method for str and unicode; a
7498 __format__() method to object, str, unicode, int, long, float, and
7499 datetime; the class string.Formatter; and the C API
7500 PyObject_Format().
7501
Georg Brandl3ee81df2008-05-17 18:14:43 +00007502- Fixed several potential crashes, all caused by specially crafted
7503 __del__ methods exploiting objects in temporarily inconsistent
7504 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007505
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007506- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007507 prevent a possible crash: an Abstract Base Class would try to access
7508 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007509
Georg Brandl3ee81df2008-05-17 18:14:43 +00007510- Fixed repr() and str() of complex numbers with infinity or nan as
7511 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007512
Georg Brandl3ee81df2008-05-17 18:14:43 +00007513- Clear all free lists during a gc.collect() of the highest generation
7514 in order to allow pymalloc to free more arenas. Python may give back
7515 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007516
Georg Brandl3ee81df2008-05-17 18:14:43 +00007517- Issue #2045: Fix an infinite recursion triggered when printing a
7518 subclass of collections.defaultdict, if its default_factory is set
7519 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007520
Christian Heimesf75dbef2008-02-08 00:11:31 +00007521- Fixed a minor memory leak in dictobject.c. The content of the free
7522 list was not freed on interpreter shutdown.
7523
Georg Brandl21e99f42010-03-07 15:23:59 +00007524- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007525 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007526
Georg Brandl3ee81df2008-05-17 18:14:43 +00007527- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7528 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007529 to compact the internal free lists of pre-allocted ints and floats.
7530
Georg Brandl3ee81df2008-05-17 18:14:43 +00007531- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7532 calls. Python expected the return type int but the fork familie
7533 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007534
Georg Brandl3ee81df2008-05-17 18:14:43 +00007535- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7536 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007537
Georg Brandl3ee81df2008-05-17 18:14:43 +00007538- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7539 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007544- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7545 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007546
Georg Brandl3ee81df2008-05-17 18:14:43 +00007547- Patch #1473257: generator objects gain a gi_code attribute. This is
7548 the same object as the func_code attribute of the function that
7549 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007550
Georg Brandl3ee81df2008-05-17 18:14:43 +00007551- Issue #1920: "while 0" statements were completely removed by the
7552 compiler, even in the presence of an "else" clause, which is
7553 supposed to be run when the condition is false. Now the compiler
7554 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007555
Guido van Rossumeead05f2008-01-24 18:21:02 +00007556- A few crashers fixed: weakref_in_del.py (issue #1377858);
7557 loosing_dict_ref.py (issue #1303614, test67.py);
7558 borrowed_ref_[34].py (not in tracker).
7559
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007560- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007561 suppressed while an extension is loaded by calling SetErrorMode in
7562 dynload_win.c. The error is still reported properly.
7563
Georg Brandl3ee81df2008-05-17 18:14:43 +00007564- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007565 several extension methods and modules do not work without unicode
7566 support.
7567
Georg Brandl26543b12008-01-21 18:36:51 +00007568- Issue #1882: when compiling code from a string, encoding cookies in the
7569 second line of code were not always recognized correctly.
7570
Georg Brandl14404b62008-01-19 19:27:05 +00007571- Issue #1679: "0x" was taken as a valid integer literal.
7572
Georg Brandl6caad7d2008-01-26 14:19:22 +00007573- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007574 added.
7575
Christian Heimesc94e2b52008-01-14 04:13:37 +00007576- sys.float_info / PyFloat_GetInfo: The floating point information
7577 object was converted from a dict to a specialized structseq object.
7578
Georg Brandl3ee81df2008-05-17 18:14:43 +00007579- Patch #1816: Added sys.flags structseq. It exposes the status of
7580 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007581
Georg Brandl3ee81df2008-05-17 18:14:43 +00007582- Objects/structseq.c: Implemented new structseq representation. The
7583 patch makes structseqs (e.g. the return value of os.stat) more
7584 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007585
Georg Brandl3ee81df2008-05-17 18:14:43 +00007586- Patch #1700288: added a type attribute cache that caches method

7595 envvar and sys.dont_write_bytecode attribute. All these can be set
7596 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007597
Georg Brandl3ee81df2008-05-17 18:14:43 +00007598- Improve some exception messages when Windows fails to load an
7599 extension module. Now we get for example '%1 is not a valid Win32
7600 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007608 and INF. float("nan"), float("inf") and float("-inf") now work on
7609 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007610
Georg Brandl3ee81df2008-05-17 18:14:43 +00007611- Compiler now generates simpler and faster code for dictionary
7612 literals. The oparg for BUILD_MAP now indicates an estimated
7613 dictionary size. There is a new opcode, STORE_MAP, for adding
7614 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007643- Patch #1739468: Directories and zipfiles containing a __main__.py
7644 file can now be directly executed by passing their name to the
7645 interpreter. The directory/zipfile is automatically inserted as the
7646 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007647
Georg Brandl3ee81df2008-05-17 18:14:43 +00007648- Issue #1265: Fix a problem with sys.settrace, if the tracing
7649 function uses a generator expression when at the same time the
7650 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007651
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007652- sets and frozensets now have an isdisjoint() method.

7657
Georg Brandl21e99f42010-03-07 15:23:59 +00007658- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007659 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7660 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007661
Georg Brandl3ee81df2008-05-17 18:14:43 +00007662- Issue #1686386: Tuple's tp_repr did not take into account the
7663 possibility of having a self-referential tuple, which is possible
7664 from C code. Nor did object's tp_str consider that a type's tp_str
7665 could do something that could lead to an inifinite recursion.
7666 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7667 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007668
Georg Brandl3ee81df2008-05-17 18:14:43 +00007669- Issue #1164: It was possible to trigger deadlock when using the
7670 'print' statement to write to a file since the GIL was not released
7671 as needed. Now PyObject_Print() does the right thing along with
7672 various tp_print implementations of the built-in types and those in
7673 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007674
Georg Brandl3ee81df2008-05-17 18:14:43 +00007675- Issue #1147: Exceptions were directly allowing string exceptions in
7676 their throw() method even though string exceptions no longer
7677 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007678
Georg Brandl3ee81df2008-05-17 18:14:43 +00007679- Issue #1096: Prevent a segfault from getting the repr of a very
7680 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007681
Brett Cannon1e534b52007-09-07 04:18:30 +00007682- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007683 PyObject_Call() never calling back out to Python code to trigger
7684 recursion depth updates/checks. Required the creation of a static
7685 RuntimeError instance in case normalizing an exception put the
7686 recursion check value past its limit. Fixes crashers
7687 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007688
Georg Brandl3ee81df2008-05-17 18:14:43 +00007689- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007702- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007703 __*__ attributes. (Some already existed, e.g., __doc__ and
7704 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007705
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007706- Add -3 option to the interpreter to warn about features that are
7707 deprecated and will be changed/removed in Python 3.0.
7708
Georg Brandl2134e752007-05-21 20:34:16 +00007709- Patch #1686487: you can now pass any mapping after '**' in function
7710 calls.
7711
Collin Winter62903052007-05-18 23:11:24 +00007712- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007713 "except E as target:". This is to provide forwards compatibility
7714 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007715
Brett Cannon229cee22007-05-05 01:34:02 +00007716- Deprecate BaseException.message as per PEP 352.
7717
Georg Brandl3ee81df2008-05-17 18:14:43 +00007718- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007719 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007720
Vinay Sajip8549ce32007-05-06 17:53:37 +00007721- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007722 setting a plain string, ie don't expand to single letter identifiers.
7723
Raymond Hettinger13936692007-04-11 18:40:58 +00007724- Request #1191699: Slices can now be pickled.
7725
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007726- Request #1193128: str.translate() now allows a None argument for
7727 translations that only remove characters without re-mapping the
7728 remaining characters.
7729
Georg Brandl5cb76c12007-03-21 09:00:39 +00007730- Patch #1682205: a TypeError while unpacking an iterable is no longer
7731 masked by a generic one with the message "unpack non-sequence".
7732
Neal Norwitzaa754b72007-03-21 06:39:48 +00007733- Remove unused file Python/fmod.c.
7734
Guido van Rossum143b5642007-03-23 04:58:42 +00007735- Bug #1683368: The object.__init__() and object.__new__() methods are
7736 now stricter in rejecting excess arguments. The only time when
7737 either allows excess arguments is when it is not overridden and the
7738 other one is. For backwards compatibility, when both are
7739 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007740 warning later). Also, type.__init__() insists on the same signature
7741 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007742
Georg Brandl3ee81df2008-05-17 18:14:43 +00007743- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7744 object to complex using its __complex__() method before falling back
7745 to the __float__() method. Therefore, the functions in the cmath
7746 module now can operate on objects that define a __complex__()
7747 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007748
Georg Brandl3ee81df2008-05-17 18:14:43 +00007749- Patch #1623563: allow __class__ assignment for classes with
7750 __slots__. The old and the new class are still required to have the
7751 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007752

7757 ``object.__reduce_ex__()`` is called with an object that is faking
7758 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007759
Georg Brandl3ee81df2008-05-17 18:14:43 +00007760- Patch #1680015: Don't modify __slots__ tuple if it contains an

7764
Georg Brandl7b9c5552007-03-12 14:30:05 +00007765- Bug #1678647: write a newline after printing an exception in any
7766 case, even when converting the value to a string failed.
7767
Georg Brandl871f1bc2007-03-12 13:17:36 +00007768- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007769 its argument, if it exists. If not, it will work like before. This
7770 allows customizing the output of dir() in the presence of a
7771 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007772
Collin Winter276887b2007-03-12 16:11:39 +00007773- Patch #922167: Python no longer segfaults when faced with infinitely
7774 self-recursive reload() calls (as reported by bug #742342).
7775
Georg Brandl3ee81df2008-05-17 18:14:43 +00007776- Patch #1675981: remove unreachable code from ``type.__new__()``
7777 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007779- Patch #1491866: change the complex() constructor to allow
7780 parthensized forms. This means complex(repr(x)) now works instead of
7781 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007782
Georg Brandlaa2321b2007-03-07 00:40:28 +00007783- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007784 makes the filenames the warning module prints much more sensible
7785 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007786
Georg Brandl49aafc92007-03-07 00:34:46 +00007787- Variant of patch #697613: don't exit the interpreter on a SystemExit
7788 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007789 variable is given, but break into the interactive interpreter just
7790 like on other exceptions or normal program exit.

7796 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00007797
Georg Brandl0fca97a2007-03-05 22:28:08 +00007798- Patch #1674228: when assigning a slice (old-style), check for the
7799 sq_ass_slice instead of the sq_slice slot.
7800
Georg Brandl3ee81df2008-05-17 18:14:43 +00007801- When printing an unraisable error, don't print exceptions. before
7802 the name. This duplicates the behavior whening normally printing
7803 exceptions.

Georg Brandl4e933132006-09-06 20:05:58 +00007886- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Guido van Rossum8bc09652008-02-21 18:18:37 +00007945- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00008354- Patch #1530482: add pydoc.render_doc() which returns the

8369
Georg Brandl92a6bae2007-03-13 17:43:32 +00008370- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008371 are set for invalid interpolation sequences that would lead to

8428 TestCase and TestSuite subclasses (not instances) are no longer
8429 accepted in TestSuite.addTest(). This should cause no
8430 incompatibility since it never made sense with ordinary subclasses
8431 -- the failure just occurred later, with a more cumbersome
8432 exception.

8705 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008706
Georg Brandl3ee81df2008-05-17 18:14:43 +00008707- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8708 with RFC 3207 and forgets any knowledge obtained from the server not
8709 obtained from the TLS negotiation itself. Patch contributed by Bill
8710 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008711
Georg Brandl3ee81df2008-05-17 18:14:43 +00008712- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008713 that the SMTP.starttls() caller no longer needs to call ehlo()
8714 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008715 does not claim to support starttls. Adds the
8716 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8717 Fenner.

8755
Georg Brandl3ee81df2008-05-17 18:14:43 +00008756- Patch #1663329: added ``os.closerange()`` function to quickly close

8797 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8798 silently miscode subclasses of those types. Now, it raises a
8799 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008800

Georg Brandl3ee81df2008-05-17 18:14:43 +00008815 time so that opening a database previously created with the DB_DUP
8816 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8817 opens. Specifically: dictionary assignment to a DB object will
8818 replace all values for a given key when the database allows
8819 duplicate values. DB users should use DB.put(k, v) when they want
8820 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008821

8827 characters with ASCII value less than 32. Also, it correctly quotes
8828 dots only if they occur on a single line, as opposed to the previous
8829 behavior of quoting dots if they are the second character of any
8830 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008831
Georg Brandla47337f2007-03-13 12:34:25 +00008832- Bug #1622896: fix a rare corner case where the bz2 module raised an

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009108- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00009109 periodic threadstate and signal checking in tight loops. By
9110 default, this option is turned-off. It should only be enabled in
9111 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009112

9162-----
9163
Georg Brandl3ee81df2008-05-17 18:14:43 +00009164- Unified naming convention for free lists and their limits. All free
9165 lists in Object/ are named ``free_list``, the counter ``numfree``
9166 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9167 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009168
Georg Brandl3ee81df2008-05-17 18:14:43 +00009169- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9170 to ``PyTuple_SetItem``, it can be used to populate a brand new
9171 frozenset; but it does not steal a reference to the added item.

9182 ``PyFloat_GetInfo()`` to the float API.
9183
Georg Brandl3ee81df2008-05-17 18:14:43 +00009184- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9185 of w# format code incorrectly truncated the length to an int, even
9186 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9187 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009188
Georg Brandl3ee81df2008-05-17 18:14:43 +00009189- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9209
9210- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9211 outside of pystate.c and should not be necessary.
9212
Georg Brandl3ee81df2008-05-17 18:14:43 +00009213- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9214 absolute imports. In earlier versions they might have used relative
9215 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009216
Georg Brandl3ee81df2008-05-17 18:14:43 +00009217- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9218 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009219
Georg Brandl3ee81df2008-05-17 18:14:43 +00009220- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009245- Removed the macfs module. It had been deprecated since Python 2.5.
9246 This lead to the deprecation of macostools.touched() as it relied
9247 solely on macfs and was a no-op under OS X.
