Mark Dickinsona96b0d12011-09-24 09:01:16 +0100313 compiler optimizing the check away. Also fix similar overflow checks
314 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
315 bugs caused test failures with recent versions of Clang.

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

Ned Deily0d0ea482012-02-10 12:59:06 +0100390- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
391 Distutils-based packages with C extension modules may fail because
392 Apple has removed gcc-4.2, the version used to build python.org
393 64-bit/32-bit Pythons. If the user does not explicitly override
394 the default C compiler by setting the CC environment variable,
395 Distutils will now attempt to compile extension modules with clang
396 if gcc-4.2 is required but not found. Also as a convenience, if
397 the user does explicitly set CC, substitute its value as the default
398 compiler in the Distutils LDSHARED configuration variable for OS X.
399 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
400 SDK, neither of which are available in Xcode 4. This change does not
401 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700674- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
675 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
676 interpreter process. This could cause failures in non-Distutils subprocesses
677 and was unreliable since tests or user programs could modify the interpreter
678 environment after Distutils set it. Instead, have Distutils set the the
679 deployment target only in the environment of each build subprocess. It is
680 still possible to globally override the default by setting
681 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
682 greater or equal to the default value, the value with which the interpreter
683 was built.

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

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00001509- Issue #9869: Make long() and PyNumber_Long return something of type
1510 long for a class whose __long__ method returns a plain int. This
1511 fixes an interpreter crash when initializing an instance of a long

1517 thread-local storage key.
1518
Victor Stinnercaafd772010-09-08 10:51:01 +00001519- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
1520 encoding and errors attributes instead of using utf-8 in strict mode, to get
1521 the same behaviour than the print statement.
1522
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00001523- Issue #9737: Fix a crash when trying to delete a slice or an item from

1538 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
1539 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

1654 by Andrew Bennetts.

1663
Raymond Hettinger20397532010-09-12 02:11:45 +00001664- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1665 This prevents user-created self-referencing ordered dictionaries from
1666 becoming permanently uncollectable GC garbage. The downside is that
1667 removing __del__ means that the internal doubly-linked list has to wait for
1668 GC collection rather than freeing memory immediately when the refcnt drops
1669 to zero.
1670

1674
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001675- Issue #9792: In case of connection failure, socket.create_connection()
1676 would swallow the exception and raise a new one, making it impossible
1677 to fetch the original errno, or to filter timeout errors. Now the
1678 original error is re-raised.
1679
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001680- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

1682 be updated back after the system call. Original patch by Brian Brazil.

Daniel Stutzbach66c981b2010-08-31 20:29:39 +00001690- Issue #808164: Fixed socket.close to avoid references to globals, to

1699
R. David Murray7c4bf552010-08-25 01:45:57 +00001700- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1701 character years even if the message contains RFC822 two character years.

1716
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001717- Issue #9617: Signals received during a low-level write operation aren't

1719
Benjamin Peterson52c36052010-08-21 03:03:22 +00001720- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1722
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001723- Issue #9626: the view methods for collections.OrderedDict() were returning

1729 without this marker will not be overwritten or removed.
1730
Antoine Pitroue1436d12010-08-12 15:25:51 +00001731- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
1732 and a BadZipfile error is raised if it doesn't match (as used to be the
1733 case in Python 2.5 and earlier).
1734
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001735- Issue #9550: a BufferedReader could issue an additional read when the

1737 when the underlying raw IO channel was e.g. a socket. Report and original
1738 patch by Jason V. Miller.
1739
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001740- Issue #9551: Don't raise TypeError when setting the value to None for

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002128- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2129 start byte and the continuation byte(s) are now considered invalid, instead
2130 of the number of bytes specified by the start byte.
2131 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2132 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2133 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2134 Previous versions returned a single u'\ufffd'.

2143 objects. (1) The comparison could incorrectly return True in some cases
2144 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2145 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00002340- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2341 operation raises multiple signals and more than one of those signals is
2342 trapped, the specification determines the order in which the signals should be
2343 handled. In many cases this order wasn't being followed, leading to the wrong
2344 Python exception being raised.

2515
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002516- Issue #8329: Don't return the same lists from select.select when no fds are
2517 changed.
2518
Georg Brandlfee0f442010-05-22 21:26:21 +00002519- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

Georg Brandlfee0f442010-05-22 21:26:21 +00002529- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2530 with a non-empty format string. This is an effort to future-proof user
2531 code. If a derived class does not currently implement __format__ but later
2532 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002533 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002534 Python 3.3 and it will be an error in Python 3.4.

2586 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2587 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00002589- Issue #2531: Comparison operations between floats and Decimal instances now
2590 return a result based on the numeric values of the operands; previously they
2591 returned an arbitrary result based on the relative ordering of id(float) and
2592 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00002595 argument `-` which tells it to read files to compile from stdin. Each line is
2596 read on demand and the named file is compiled immediately. (Original patch by
2597 Piotr Ożarowski).

2607 Fractions instance now raise TypeError instead of returning True/False. This
2608 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2609 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002713- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2714 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00002716 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2717 inconsistent: __int__ was used for some integer codes but not for others, and
2718 the set of integer codes for which it was used differed between native packing
2719 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003027 file position when calling `truncate()`. It would previously change the file
3028 position to the given argument, which goes against the tradition of

3032 class used to represent files stored inside an archive. The new
3033 implementation is significantly faster and can be wrapped in a
3034 ``io.BufferedReader`` object for more speedups. It also solves an issue
3035 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003126- The ``__complex__()`` method is now looked up on the class of instances to
3127 make it consistent with other special methods.

3131
Mark Dickinson1b34d252010-01-01 17:27:30 +00003132- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003133 DeprecationWarning when passed a float argument where an integer was expected.
3134 These functions and methods now raise TypeError instead. The majority of the
3135 effects of this change are in the extension modules, but some core functions
3136 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3137 and many unicode/str methods.

3303 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3304 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003305
Georg Brandlba83f822010-03-14 09:50:54 +00003306- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3307 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003308
Georg Brandlba83f822010-03-14 09:50:54 +00003309- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3310 1e-100 used to raise OverflowError, but now gives the requested 120
3311 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003319
Georg Brandlba83f822010-03-14 09:50:54 +00003320- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3321 decimal string that's guaranteed to round back to x under correct rounding
3322 (with round-half-to-even rounding mode). Previously it gave a string based on
3323 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3324 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3325 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003326
Georg Brandlba83f822010-03-14 09:50:54 +00003327- Issue #7117: On almost all platforms: float-to-string and string-to-float
3328 conversions within Python are now correctly rounded. Places these conversions
3329 occur include: str for floats and complex numbers; the float and complex
3330 constructors; old-style and new-style numeric formatting; serialization and
3331 deserialization of floats and complex numbers using marshal, pickle and json;
3332 parsing of float and imaginary literals in Python code; Decimal-to-float
3333 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003334
Georg Brandlba83f822010-03-14 09:50:54 +00003335 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3336 providing correctly-rounded strtod and dtoa C functions. This code is
3337 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3338 the C compiler. There may be a small number of platforms on which correct
3339 operation of this code cannot be guaranteed, so the code is not used: notably,
3340 this applies to platforms where the C double format is not IEEE 754 binary64,
3341 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3342 and Python's configure script is unable to determine how to change the FPU
3343 precision. On these platforms conversions use the platform strtod and dtoa,
3344 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003345
Georg Brandlba83f822010-03-14 09:50:54 +00003346- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3347 uses the correctly-rounded string <-> float conversions described above (when
3348 available), and so produces correctly rounded results that will display nicely
3349 under the float repr. There are two related small changes: (1) round now
3350 accepts any class with an ``__index__()`` method for its second argument (but
3351 no longer accepts floats for the second argument), and (2) an excessively
3352 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3353 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003495
Georg Brandlba83f822010-03-14 09:50:54 +00003496 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3497 (2) parsing of strings representing infinities and nans was locale aware; and
3498 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003500- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3501 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3502 but with at least one decimal point and with a default precision
3503 of 12. Previously, the behavior the same but with a default precision of 6.
3504 This more closely matches ``str()``, and reduces surprises when adding
3505 alignment flags to the empty presentation type. This also affects the new
3506 complex.__format__ in the same way.
3507
3508- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3509 classtype's, even if it was None. property now inserts the __doc__ into the
3510 subclass instance __dict__.

3580 internal representation of integers, for performance reasons. Base 2**30 is
3581 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl2bd92a52009-10-11 21:10:07 +00005114- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00005115 AttributeError instead of RuntimeError, depending in which C API call
5116 exactly the recursion limit is exceeded. Consequently, both exception types
5117 are caught and silenced.

5133
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005134- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5135
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005136- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5137 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5138 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5139 ``printf`` function, whereas PyString_FromFormat has an independent
5140 implementation and uses "%zd" on all platforms for size_t values.
5141 This makes a difference on win64, where ``printf`` needs "%Id" to display
5142 64bit values.
5143
Benjamin Peterson97179b02008-09-09 20:55:01 +00005144- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5145 error.
5146
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005147- Issue #3777: long() applied to a float object now always return a long
5148 object; previously an int would be returned for small values. the __long__
5149 method is allowed to return either an int or a long, but the behaviour of
5150 float objects should not change to respect backward compatibility.
5151
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005152- Issue #3751: str.rpartition would perform a left-partition when called with
5153 a unicode argument.
5154
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005155- Issue #3683: Fix compilation when --without-threads is given.
5156
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005157- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005158 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005159 was correctly parsed but parsing of subsequent arguments failed.
5160
Vinay Sajip35e3b032008-09-01 14:33:59 +00005161- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005162 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5163 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5164 when given a tuple of classes as second argument, were looking up
5165 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5166 type object.
5167
Neal Norwitz18aa3882008-08-24 05:04:52 +00005168- Fix crashes on memory allocation failure found with failmalloc.
5169
5170- Fix memory leaks found with valgrind and update suppressions file.
5171
5172- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5173
5174- Fix problem using wrong name in decimal module reported by pychecker.
5175
Christian Heimes7d4c3172008-08-22 19:47:25 +00005176- Silenced another compiler warning about a used but not defined
5177 function 'stringlib_contains_obj'.
5178
Benjamin Peterson712ee922008-08-24 18:10:20 +00005179- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5180 ``__delslice__``.
5181
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005182- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5183 library targets in the Makefile.
5184
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005185- Issue #1204: The configure script now tests for additional libraries
5186 that may be required when linking against readline. This fixes issues
5187 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00005211 return a list or None rather than a custom object.
5212
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005213- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005237 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5238 for catch_warnings() also led to an improvement in the raising of a
5239 DeprecationWarning related to warnings.warn_explicit().
5240
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005241- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005305What's New in Python 2.6 beta 3?
5306================================
5307
Barry Warsaw07a4a382008-08-21 01:15:08 +00005308*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005309
5310Core and Builtins
5311-----------------
5312
Guido van Rossumf8402962008-08-20 15:01:50 +00005313- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5314 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5315 extensions do not automatically benefit from the class attribute
5316 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5317 to their tp_flags field if they care. This is a backwards
5318 compatibility feature; in 3.0, all types will use the cache by
5319 default.
5320
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005321- Keyword arguments can now follow starred arguments. (``f(a, *args,
5322 keyword=23)`` is now valid syntax.)
5323
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005324- ctypes function pointers that are COM methods have a boolean True
5325 value again.
5326
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005327- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5328 by denying s# to parse objects that have a releasebuffer procedure,
5329 and introducing s*.
5330
Georg Brandl1e13ea92008-08-11 09:07:59 +00005331- Issue #3537: Fix an assertion failure when an empty but presized dict
5332 object was stored in the freelist.
5333
Mark Dickinsonb6467572008-08-04 21:30:09 +00005334- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5335 ValueError consistently across platforms.
5336
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005337- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5338 (64bit Unix, for example), unichr() would truncate its argument and return
5339 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5340
Neal Norwitze7d8be82008-07-31 17:17:14 +00005341- Apply security patches from Apple.
5342
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005343- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5344 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5345
Antoine Pitrou92f82162008-07-25 22:22:08 +00005346- Issue #1819: function calls with several named parameters are now on
5347 average 35% faster (as measured by pybench).
5348
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005349- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5350 the python debugger steps into a class statement: the free variables (local
5351 variables defined in an outer scope) would be deleted from the outer scope.
5352
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005353- Issue #2620: Overflow checking when allocating or reallocating memory
5354 was not always being done properly in some python types and extension
5355 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5356 all been updated to perform better checks and places in the code that
5357 would previously leak memory on the error path when such an allocation
5358 failed have been fixed.

5364
Benjamin Petersone977ad42008-08-20 01:42:01 +00005365- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5366 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5367
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005368- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5369 version reported by these tools does not necessarily follow the python
5370 version numbering scheme, so the module is less strict when parsing it.
5371
Nick Coghlanf70385a2008-08-18 12:42:46 +00005372- Issue #2235: Added Py3k warnings for types which will become unhashable
5373 under the stricter __hash__ inheritance rules in 3.0. Several types
5374 which did not meet the rules for hash invariants and were already
5375 unhashable in 3.0 have now been explicitly flagged as unhashable in
5376 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5377 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5378
Brett Cannon88f801d2008-08-18 00:46:22 +00005379- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5380 imported into the module but exposed as part of the module's API.
5381
Brett Cannon7b96f072008-08-18 00:41:11 +00005382- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005386- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5387
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005388- Issue #3575: Incremental decoder's decode function now takes bytearray
5389 by using 's*' instead of 't#'.
5390
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005391- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005392 fails unicode conversion on 2nd parameter. (windows only)

Antoine Pitroude781a42008-08-09 12:43:23 +00005448 asking for a specific length. This problem only affected files opened

5492
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005493- Issue #643841: The language reference now provides more detailed

5505-----------------
5506
Georg Brandl3e483f62008-07-16 22:57:41 +00005507- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5508 its methods now allow for items objects that can be converted to
5509 an integer using operator.index().
5510
Mark Dickinson64b7e502008-07-16 09:40:03 +00005511- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5512 produced a ValueError instead of giving the correct float.
5513
Eric Smitha5fa5a22008-07-16 00:11:49 +00005514- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5515 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5516
Mark Dickinson7103aa42008-07-15 19:08:33 +00005517- Issue #3008: the float type has a new instance method 'float.hex'
5518 and a new class method 'float.fromhex' to convert floating-point
5519 numbers to and from hexadecimal strings, respectively.
5520
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005521- Issue #2235: __hash__ is once again inherited by default. To allow
5522 collections.Hashable to remain meaningful in the presence of the
5523 default hash implementation (object.__hash__), it is now possible
5524 to explicit block inheritance of hash by setting __hash__=None at
5525 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5526 level.
5527
Nick Coghlanb028f502008-07-13 14:52:36 +00005528- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5529 the parent module cannot be found while performing an absolute import.
5530 This means that an incorrectly defined __package__ attribute will
5531 now only prevent relative imports in that module rather than causing
5532 all imports from that module to fail.
5533
Nick Coghlan14ff9942008-07-08 14:21:42 +00005534- Issue #2517: Allow unicode messages in Exceptions again by correctly
5535 bypassing the instance dictionary when looking up __unicode__ on
5536 new-style classes.

5544 another thread's dictionary.
5545
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005546- Issue #3004: Minor change to slice.indices(): the start and stop
5547 arguments are now treated identically, making the behaviour easier
5548 to describe and understand. For example, slice(None, -10,
5549 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5550 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5551 10, -1).
5552
Georg Brandl278fc502008-07-19 12:46:12 +00005553- Issue #3219: Calling a function with repeated keyword arguments,
5554 f(a=2, a=23), would not cause a syntax error. This was a regression
5555 from 2.4 caused by the switch to the new compiler.

5565 api functions without holding the GIL, which could lead to a fatal
5566 error when they failed.
5567
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005568- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005593- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5594 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005595 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005596 content-length. The problem had been corrected in the 2.4 branch, but never
5597 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005612- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6002
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006003- On MacOS X it is now possible to install the framework in 64-bit
6004 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006005 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006006
6007 This is controlled by the configure argument ``--with-universal-archs``:
6008
6009 - ``--with-universal-archs=all``: install 4-way universal
6010
6011 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6012
6013 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6014
6015 This option should be used in combination with ``--enable-universalsdk=``.
6016
6017 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 +00006067- Issue #1631171: Re-implement the 'warnings' module in C (the
6068 original Python code has been kept as backup). This will allow for
6069 using the 'warning's machinery in such places as the parser where
6070 use of pure Python code is not possible. Both the ``showarning()``
6071 and ``formatwarning()`` gain an optional 'line' argument which is
6072 not called by default for backwards-compatibility reasons. Setting
6073 ``warnings.showwarning()`` to an implementation that lacks support
6074 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006137- Issue #2550: The approach used by client/server code for obtaining
6138 ports to listen on in network-oriented tests has been refined in an
6139 effort to facilitate running multiple instances of the entire
6140 regression test suite in parallel without issue.
6141 test_support.bind_port() has been fixed such that it will always
6142 return a unique port -- which wasn't always the case with the
6143 previous implementation, especially if socket options had been set
6144 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6145 new implementation of bind_port() will actually raise an exception
6146 if it is passed an AF_INET/SOCK_STREAM socket with either the
6147 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6148 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6149 the socket it's been passed. This currently only applies to
6150 Windows. This option prevents any other sockets from binding to the
6151 host/port we've bound to, thus removing the possibility of the
6152 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6153 when a second SOCK_STREAM socket binds and accepts to a host/port
6154 that's already been bound by another socket. The optional preferred
6155 port parameter to bind_port() has been removed. Under no
6156 circumstances should tests be hard coding ports!
6157
6158 test_support.find_unused_port() has also been introduced, which will
6159 pass a temporary socket object to bind_port() in order to obtain an
6160 unused port. The temporary socket object is then closed and
6161 deleted, and the port is returned. This method should only be used
6162 for obtaining an unused port in order to pass to an external program
6163 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6164 a parameter to a server-oriented class that doesn't give you direct
6165 access to the underlying socket used.
6166
6167 Finally, test_support.HOST has been introduced, which should be used
6168 for the host argument of any relevant socket calls (i.e. bind and
6169 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006170
6171 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006172 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006173 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6174 test_asynchat and test_socket_ssl.
6175
Georg Brandl3ee81df2008-05-17 18:14:43 +00006176 It is now possible for multiple instances of the regression test
6177 suite to run in parallel without issue.

6235 this case, like normal unicode literals and the 'unicode-escape'
6236 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006456- Added the future_builtins module, which contains hex() and oct().
6457 These are the PEP 3127 version of these functions, designed to be
6458 compatible with the hex() and oct() builtins from Python 3.0. They
6459 differ slightly in their output formats from the existing, unchanged
6460 Python 2.6 builtins. The expected usage of the future_builtins
6461 module is:
6462 from future_builtins import hex, oct
6463
Eric Smith7ef40bf2008-02-20 23:34:22 +00006464- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6465 exponents for exponents with absolute value < 100. Follows C99
6466 standard. This is a change on Windows, which would use 3 digits.
6467 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6468 so that any alterations it does to the resulting string will be
6469 available in stringlib/formatter.h (for float.__format__).
6470
Eric Smith5a3c1352008-02-19 13:21:56 +00006471- Implemented PEP 3101, Advanced String Formatting. This adds a new
6472 builtin format(); a format() method for str and unicode; a
6473 __format__() method to object, str, unicode, int, long, float, and
6474 datetime; the class string.Formatter; and the C API
6475 PyObject_Format().
6476
Georg Brandl3ee81df2008-05-17 18:14:43 +00006477- Fixed several potential crashes, all caused by specially crafted
6478 __del__ methods exploiting objects in temporarily inconsistent
6479 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006488- Clear all free lists during a gc.collect() of the highest generation
6489 in order to allow pymalloc to free more arenas. Python may give back
6490 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006491
Georg Brandl3ee81df2008-05-17 18:14:43 +00006492- Issue #2045: Fix an infinite recursion triggered when printing a
6493 subclass of collections.defaultdict, if its default_factory is set
6494 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006495
Christian Heimesf75dbef2008-02-08 00:11:31 +00006496- Fixed a minor memory leak in dictobject.c. The content of the free
6497 list was not freed on interpreter shutdown.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006522- Patch #1473257: generator objects gain a gi_code attribute. This is
6523 the same object as the func_code attribute of the function that
6524 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006525
Georg Brandl3ee81df2008-05-17 18:14:43 +00006526- Issue #1920: "while 0" statements were completely removed by the
6527 compiler, even in the presence of an "else" clause, which is
6528 supposed to be run when the condition is false. Now the compiler
6529 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006530
Guido van Rossumeead05f2008-01-24 18:21:02 +00006531- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006535- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006536 suppressed while an extension is loaded by calling SetErrorMode in

6538
Georg Brandl3ee81df2008-05-17 18:14:43 +00006539- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006540 several extension methods and modules do not work without unicode
6541 support.
6542

6547
Georg Brandl6caad7d2008-01-26 14:19:22 +00006548- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006549 added.
6550
Christian Heimesc94e2b52008-01-14 04:13:37 +00006551- sys.float_info / PyFloat_GetInfo: The floating point information
6552 object was converted from a dict to a specialized structseq object.
6553
Georg Brandl3ee81df2008-05-17 18:14:43 +00006554- Patch #1816: Added sys.flags structseq. It exposes the status of
6555 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006556
Georg Brandl3ee81df2008-05-17 18:14:43 +00006557- Objects/structseq.c: Implemented new structseq representation. The
6558 patch makes structseqs (e.g. the return value of os.stat) more
6559 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006560
Georg Brandl3ee81df2008-05-17 18:14:43 +00006561- Patch #1700288: added a type attribute cache that caches method
6562 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006563
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006564- Bug #1776: __import__() no longer accepts filenames on any platform.
6565 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00006567- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6568
Georg Brandl3ee81df2008-05-17 18:14:43 +00006569- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6570 envvar and sys.dont_write_bytecode attribute. All these can be set
6571 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006572
Georg Brandl3ee81df2008-05-17 18:14:43 +00006573- Improve some exception messages when Windows fails to load an
6574 extension module. Now we get for example '%1 is not a valid Win32
6575 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006582- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006583 and INF. float("nan"), float("inf") and float("-inf") now work on
6584 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006585
Georg Brandl3ee81df2008-05-17 18:14:43 +00006586- Compiler now generates simpler and faster code for dictionary
6587 literals. The oparg for BUILD_MAP now indicates an estimated
6588 dictionary size. There is a new opcode, STORE_MAP, for adding
6589 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006618- Patch #1739468: Directories and zipfiles containing a __main__.py
6619 file can now be directly executed by passing their name to the
6620 interpreter. The directory/zipfile is automatically inserted as the
6621 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006623- Issue #1265: Fix a problem with sys.settrace, if the tracing
6624 function uses a generator expression when at the same time the
6625 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006626
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006627- sets and frozensets now have an isdisjoint() method.
6628
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006629- optimize the performance of builtin.sum().

6632
Georg Brandl21e99f42010-03-07 15:23:59 +00006633- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006634 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6635 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006636
Georg Brandl3ee81df2008-05-17 18:14:43 +00006637- Issue #1686386: Tuple's tp_repr did not take into account the
6638 possibility of having a self-referential tuple, which is possible
6639 from C code. Nor did object's tp_str consider that a type's tp_str
6640 could do something that could lead to an inifinite recursion.
6641 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6642 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006643
Georg Brandl3ee81df2008-05-17 18:14:43 +00006644- Issue #1164: It was possible to trigger deadlock when using the
6645 'print' statement to write to a file since the GIL was not released
6646 as needed. Now PyObject_Print() does the right thing along with
6647 various tp_print implementations of the built-in types and those in
6648 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006649
Georg Brandl3ee81df2008-05-17 18:14:43 +00006650- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00006657- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006658 PyObject_Call() never calling back out to Python code to trigger
6659 recursion depth updates/checks. Required the creation of a static
6660 RuntimeError instance in case normalizing an exception put the
6661 recursion check value past its limit. Fixes crashers
6662 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006677- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006678 __*__ attributes. (Some already existed, e.g., __doc__ and
6679 __name__.)

6683
Georg Brandl2134e752007-05-21 20:34:16 +00006684- Patch #1686487: you can now pass any mapping after '**' in function
6685 calls.
6686
Collin Winter62903052007-05-18 23:11:24 +00006687- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006688 "except E as target:". This is to provide forwards compatibility
6689 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006696- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006697 setting a plain string, ie don't expand to single letter identifiers.
6698
Raymond Hettinger13936692007-04-11 18:40:58 +00006699- Request #1191699: Slices can now be pickled.
6700
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006701- Request #1193128: str.translate() now allows a None argument for

6703 remaining characters.
6704
Georg Brandl5cb76c12007-03-21 09:00:39 +00006705- Patch #1682205: a TypeError while unpacking an iterable is no longer

6709
Guido van Rossum143b5642007-03-23 04:58:42 +00006710- Bug #1683368: The object.__init__() and object.__new__() methods are
6711 now stricter in rejecting excess arguments. The only time when
6712 either allows excess arguments is when it is not overridden and the
6713 other one is. For backwards compatibility, when both are
6714 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006715 warning later). Also, type.__init__() insists on the same signature
6716 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006718- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6719 object to complex using its __complex__() method before falling back
6720 to the __float__() method. Therefore, the functions in the cmath
6721 module now can operate on objects that define a __complex__()
6722 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006744 its argument, if it exists. If not, it will work like before. This
6745 allows customizing the output of dir() in the presence of a
6746 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00006758- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00006828- Bug #1545497: when given an explicit base, int() did ignore NULs
6829 embedded in the string to convert.
6830
Georg Brandl846f73a2006-10-08 07:11:54 +00006831- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006879 generator expressions (x for x, in ... ) works again. Fixing this
6880 problem required changing the .pyc magic number. This means that
6881 .pyc files generated before 2.5c2 will be regenerated.

7689 with RFC 3207 and forgets any knowledge obtained from the server not
7690 obtained from the TLS negotiation itself. Patch contributed by Bill
7691 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007693- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007694 that the SMTP.starttls() caller no longer needs to call ehlo()
7695 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007696 does not claim to support starttls. Adds the
7697 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7698 Fenner.

7778 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7779 silently miscode subclasses of those types. Now, it raises a
7780 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007781

Georg Brandl3ee81df2008-05-17 18:14:43 +00007796 time so that opening a database previously created with the DB_DUP
7797 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7798 opens. Specifically: dictionary assignment to a DB object will
7799 replace all values for a given key when the database allows
7800 duplicate values. DB users should use DB.put(k, v) when they want
7801 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007802

7808 characters with ASCII value less than 32. Also, it correctly quotes
7809 dots only if they occur on a single line, as opposed to the previous
7810 behavior of quoting dots if they are the second character of any
7811 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007812
