Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000141- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
142 start byte and the continuation byte(s) are now considered invalid, instead
143 of the number of bytes specified by the start byte.
144 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
145 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
146 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
147 Previous versions returned a single u'\ufffd'.

151 arises from the "Overriding __eq__ blocks inheritance ..." warning
152 when turned into an exception: in this case the exception simply
153 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000155- Issue #8748: Fix two issues with comparisons between complex and integer
156 objects. (1) The comparison could incorrectly return True in some cases
157 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
158 (2) The comparison raised an OverflowError for large integers, leading
159 to unpredictable exceptions when combining integers and complex objects
160 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +0000162- Issue #5211: Implicit coercion for the complex type is now completely
163 removed. (Coercion for arithmetic operations was already removed in 2.7
164 alpha 4, but coercion for rich comparisons was accidentally left in.)

545 adds its own __format__, it would most likely break user code that had
546 supplied a format string. This will be changed to a DeprecationWaring in
547 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00001026 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001032- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001033 file position when calling `truncate()`. It would previously change the file
1034 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001035 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1036
Georg Brandlba83f822010-03-14 09:50:54 +00001037- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1038 class used to represent files stored inside an archive. The new
1039 implementation is significantly faster and can be wrapped in a
1040 ``io.BufferedReader`` object for more speedups. It also solves an issue
1041 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1054 encoded string for them. This ensures that the upload and register commands

1130-----------------
1131
Georg Brandlba83f822010-03-14 09:50:54 +00001132- The ``__complex__()`` method is now looked up on the class of instances to
1133 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001135- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1136 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1137
Mark Dickinson1b34d252010-01-01 17:27:30 +00001138- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001139 DeprecationWarning when passed a float argument where an integer was expected.
1140 These functions and methods now raise TypeError instead. The majority of the
1141 effects of this change are in the extension modules, but some core functions
1142 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1143 and many unicode/str methods.

1157 of integers: the result of a/b is now correctly rounded for ints a and b (at
1158 least on IEEE 754 platforms), and in particular does not depend on the
1159 internal representation of a long.

1167
Georg Brandlba83f822010-03-14 09:50:54 +00001168 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00001308- Issue #3382: 'F' formatting for float and complex now convert the result to
1309 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1310 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001311
Georg Brandlba83f822010-03-14 09:50:54 +00001312- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1313 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001314
Georg Brandlba83f822010-03-14 09:50:54 +00001315- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1316 1e-100 used to raise OverflowError, but now gives the requested 120
1317 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001325
Georg Brandlba83f822010-03-14 09:50:54 +00001326- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1327 decimal string that's guaranteed to round back to x under correct rounding
1328 (with round-half-to-even rounding mode). Previously it gave a string based on
1329 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1330 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1331 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001332
Georg Brandlba83f822010-03-14 09:50:54 +00001333- Issue #7117: On almost all platforms: float-to-string and string-to-float
1334 conversions within Python are now correctly rounded. Places these conversions
1335 occur include: str for floats and complex numbers; the float and complex
1336 constructors; old-style and new-style numeric formatting; serialization and
1337 deserialization of floats and complex numbers using marshal, pickle and json;
1338 parsing of float and imaginary literals in Python code; Decimal-to-float
1339 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001340
Georg Brandlba83f822010-03-14 09:50:54 +00001341 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1342 providing correctly-rounded strtod and dtoa C functions. This code is
1343 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1344 the C compiler. There may be a small number of platforms on which correct
1345 operation of this code cannot be guaranteed, so the code is not used: notably,
1346 this applies to platforms where the C double format is not IEEE 754 binary64,
1347 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1348 and Python's configure script is unable to determine how to change the FPU
1349 precision. On these platforms conversions use the platform strtod and dtoa,
1350 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001351
Georg Brandlba83f822010-03-14 09:50:54 +00001352- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1353 uses the correctly-rounded string <-> float conversions described above (when
1354 available), and so produces correctly rounded results that will display nicely
1355 under the float repr. There are two related small changes: (1) round now
1356 accepts any class with an ``__index__()`` method for its second argument (but
1357 no longer accepts floats for the second argument), and (2) an excessively
1358 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1359 raises an exception.

1362
Georg Brandlba83f822010-03-14 09:50:54 +00001363- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001500- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00001501
Georg Brandlba83f822010-03-14 09:50:54 +00001502 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1503 (2) parsing of strings representing infinities and nans was locale aware; and
1504 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001506- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1507 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1508 but with at least one decimal point and with a default precision
1509 of 12. Previously, the behavior the same but with a default precision of 6.
1510 This more closely matches ``str()``, and reduces surprises when adding
1511 alignment flags to the empty presentation type. This also affects the new
1512 complex.__format__ in the same way.
1513
1514- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1515 classtype's, even if it was None. property now inserts the __doc__ into the
1516 subclass instance __dict__.

1738 this code path is really executed because I cannot move to such directory on

1742 element is temporarily replaced with an equivalent frozenset. But the
1743 eventual KeyError would always report the empty ``frozenset()`` as the missing
1744 key. Now it correctly refers to the initial element.

1765 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1766 step. This avoids problems with counting UTF-8 bytes that ignores the effect

Walter Dörwald726ba8e2009-05-06 14:32:35 +00001769- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001772- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1774 gives improved memory leak detection when running under Valgrind, while taking
1775 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00002998 leak-chasing test runs give sensible results. The previous method of reaping
2999 threads could return successfully while some Thread objects were still

3139
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003140- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3141
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003142- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3143 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3144 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3145 ``printf`` function, whereas PyString_FromFormat has an independent
3146 implementation and uses "%zd" on all platforms for size_t values.
3147 This makes a difference on win64, where ``printf`` needs "%Id" to display
3148 64bit values.
3149
Benjamin Peterson97179b02008-09-09 20:55:01 +00003150- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3151 error.
3152
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003153- Issue #3777: long() applied to a float object now always return a long
3154 object; previously an int would be returned for small values. the __long__
3155 method is allowed to return either an int or a long, but the behaviour of
3156 float objects should not change to respect backward compatibility.
3157
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003158- Issue #3751: str.rpartition would perform a left-partition when called with
3159 a unicode argument.
3160
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003161- Issue #3683: Fix compilation when --without-threads is given.
3162
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003163- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003164 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003165 was correctly parsed but parsing of subsequent arguments failed.
3166
Vinay Sajip35e3b032008-09-01 14:33:59 +00003167- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003168 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3169 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3170 when given a tuple of classes as second argument, were looking up
3171 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3172 type object.
3173
Neal Norwitz18aa3882008-08-24 05:04:52 +00003174- Fix crashes on memory allocation failure found with failmalloc.
3175
3176- Fix memory leaks found with valgrind and update suppressions file.
3177
3178- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3179
3180- Fix problem using wrong name in decimal module reported by pychecker.
3181
Christian Heimes7d4c3172008-08-22 19:47:25 +00003182- Silenced another compiler warning about a used but not defined
3183 function 'stringlib_contains_obj'.
3184

3186 ``__delslice__``.
3187
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003188- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3189 library targets in the Makefile.
3190
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003191- Issue #1204: The configure script now tests for additional libraries
3192 that may be required when linking against readline. This fixes issues
3193 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00003216- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003217 return a list or None rather than a custom object.

3243 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3244 for catch_warnings() also led to an improvement in the raising of a
3245 DeprecationWarning related to warnings.warn_explicit().
3246
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003247- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003311What's New in Python 2.6 beta 3?
3312================================
3313
Barry Warsaw07a4a382008-08-21 01:15:08 +00003314*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003315
3316Core and Builtins
3317-----------------
3318
Guido van Rossumf8402962008-08-20 15:01:50 +00003319- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3320 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3321 extensions do not automatically benefit from the class attribute
3322 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3323 to their tp_flags field if they care. This is a backwards
3324 compatibility feature; in 3.0, all types will use the cache by
3325 default.
3326
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003327- Keyword arguments can now follow starred arguments. (``f(a, *args,
3328 keyword=23)`` is now valid syntax.)
3329
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003330- ctypes function pointers that are COM methods have a boolean True
3331 value again.
3332
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003333- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3334 by denying s# to parse objects that have a releasebuffer procedure,
3335 and introducing s*.
3336
Georg Brandl1e13ea92008-08-11 09:07:59 +00003337- Issue #3537: Fix an assertion failure when an empty but presized dict
3338 object was stored in the freelist.
3339
Mark Dickinsonb6467572008-08-04 21:30:09 +00003340- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3341 ValueError consistently across platforms.
3342
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003343- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3344 (64bit Unix, for example), unichr() would truncate its argument and return
3345 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3346
Neal Norwitze7d8be82008-07-31 17:17:14 +00003347- Apply security patches from Apple.
3348
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003349- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3350 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3351
Antoine Pitrou92f82162008-07-25 22:22:08 +00003352- Issue #1819: function calls with several named parameters are now on
3353 average 35% faster (as measured by pybench).
3354
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003355- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3356 the python debugger steps into a class statement: the free variables (local
3357 variables defined in an outer scope) would be deleted from the outer scope.
3358
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003359- Issue #2620: Overflow checking when allocating or reallocating memory
3360 was not always being done properly in some python types and extension
3361 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3362 all been updated to perform better checks and places in the code that
3363 would previously leak memory on the error path when such an allocation
3364 failed have been fixed.

3368
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003369- Issue #3612: Added some missing basic types in ctypes.wintypes.

Benjamin Petersone977ad42008-08-20 01:42:01 +00003371- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3372 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3373
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003374- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3375 version reported by these tools does not necessarily follow the python
3376 version numbering scheme, so the module is less strict when parsing it.
3377
Nick Coghlanf70385a2008-08-18 12:42:46 +00003378- Issue #2235: Added Py3k warnings for types which will become unhashable
3379 under the stricter __hash__ inheritance rules in 3.0. Several types
3380 which did not meet the rules for hash invariants and were already
3381 unhashable in 3.0 have now been explicitly flagged as unhashable in
3382 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3383 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3384
Brett Cannon88f801d2008-08-18 00:46:22 +00003385- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3386 imported into the module but exposed as part of the module's API.
3387
Brett Cannon7b96f072008-08-18 00:41:11 +00003388- Remove an unneeded import of abc.ABCMeta from 'inspect'.

3393
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003394- Issue #3575: Incremental decoder's decode function now takes bytearray
3395 by using 's*' instead of 't#'.
3396
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003397- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003398 fails unicode conversion on 2nd parameter. (windows only)
3399
Facundo Batista94f243a2008-08-17 03:38:39 +00003400- Issue 2464. urllib2 now supports a malformation in the URL received
3401 in a redirect.
3402

Antoine Pitroude781a42008-08-09 12:43:23 +00003454 asking for a specific length. This problem only affected files opened

3482 mode 0600 rather than 000 under Unix.
3483

3498
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003499- Issue #643841: The language reference now provides more detailed

3512
Georg Brandl3e483f62008-07-16 22:57:41 +00003513- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3514 its methods now allow for items objects that can be converted to
3515 an integer using operator.index().
3516
Mark Dickinson64b7e502008-07-16 09:40:03 +00003517- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3518 produced a ValueError instead of giving the correct float.
3519
Eric Smitha5fa5a22008-07-16 00:11:49 +00003520- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3521 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3522
Mark Dickinson7103aa42008-07-15 19:08:33 +00003523- Issue #3008: the float type has a new instance method 'float.hex'
3524 and a new class method 'float.fromhex' to convert floating-point
3525 numbers to and from hexadecimal strings, respectively.
3526
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003527- Issue #2235: __hash__ is once again inherited by default. To allow
3528 collections.Hashable to remain meaningful in the presence of the
3529 default hash implementation (object.__hash__), it is now possible
3530 to explicit block inheritance of hash by setting __hash__=None at
3531 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3532 level.
3533
Nick Coghlanb028f502008-07-13 14:52:36 +00003534- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3535 the parent module cannot be found while performing an absolute import.
3536 This means that an incorrectly defined __package__ attribute will
3537 now only prevent relative imports in that module rather than causing
3538 all imports from that module to fail.
3539
Nick Coghlan14ff9942008-07-08 14:21:42 +00003540- Issue #2517: Allow unicode messages in Exceptions again by correctly

3550 another thread's dictionary.
3551
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003552- Issue #3004: Minor change to slice.indices(): the start and stop
3553 arguments are now treated identically, making the behaviour easier
3554 to describe and understand. For example, slice(None, -10,
3555 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3556 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3557 10, -1).
3558
Georg Brandl278fc502008-07-19 12:46:12 +00003559- Issue #3219: Calling a function with repeated keyword arguments,
3560 f(a=2, a=23), would not cause a syntax error. This was a regression
3561 from 2.4 caused by the switch to the new compiler.

3600 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003601 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003602 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003618- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Brett Cannonb61d8012008-05-11 23:39:04 +00004007- ``Lib/lib-old`` is now added to sys.path.
4008
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004009- On MacOS X it is now possible to install the framework in 64-bit
4010 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004011 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004012
4013 This is controlled by the configure argument ``--with-universal-archs``:
4014
4015 - ``--with-universal-archs=all``: install 4-way universal
4016
4017 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4018
4019 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4020
4021 This option should be used in combination with ``--enable-universalsdk=``.
4022
4023 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 +00004073- Issue #1631171: Re-implement the 'warnings' module in C (the
4074 original Python code has been kept as backup). This will allow for
4075 using the 'warning's machinery in such places as the parser where
4076 use of pure Python code is not possible. Both the ``showarning()``
4077 and ``formatwarning()`` gain an optional 'line' argument which is
4078 not called by default for backwards-compatibility reasons. Setting
4079 ``warnings.showwarning()`` to an implementation that lacks support
4080 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004143- Issue #2550: The approach used by client/server code for obtaining
4144 ports to listen on in network-oriented tests has been refined in an
4145 effort to facilitate running multiple instances of the entire
4146 regression test suite in parallel without issue.
4147 test_support.bind_port() has been fixed such that it will always
4148 return a unique port -- which wasn't always the case with the
4149 previous implementation, especially if socket options had been set
4150 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4151 new implementation of bind_port() will actually raise an exception
4152 if it is passed an AF_INET/SOCK_STREAM socket with either the
4153 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4154 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4155 the socket it's been passed. This currently only applies to
4156 Windows. This option prevents any other sockets from binding to the
4157 host/port we've bound to, thus removing the possibility of the
4158 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4159 when a second SOCK_STREAM socket binds and accepts to a host/port
4160 that's already been bound by another socket. The optional preferred
4161 port parameter to bind_port() has been removed. Under no
4162 circumstances should tests be hard coding ports!
4163
4164 test_support.find_unused_port() has also been introduced, which will
4165 pass a temporary socket object to bind_port() in order to obtain an
4166 unused port. The temporary socket object is then closed and
4167 deleted, and the port is returned. This method should only be used
4168 for obtaining an unused port in order to pass to an external program
4169 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4170 a parameter to a server-oriented class that doesn't give you direct
4171 access to the underlying socket used.
4172
4173 Finally, test_support.HOST has been introduced, which should be used
4174 for the host argument of any relevant socket calls (i.e. bind and
4175 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004176
4177 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004179 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4180 test_asynchat and test_socket_ssl.
4181
Georg Brandl3ee81df2008-05-17 18:14:43 +00004182 It is now possible for multiple instances of the regression test
4183 suite to run in parallel without issue.

4450-----------------
4451
Fred Drakea8ee94b2008-03-01 02:45:07 +00004452- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004453 644. The mode is now inherited from the py file.

4456
4457- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004458
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004459- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004460 issue 215555 for a discussion.
4461
Eric Smitha73fbe72008-02-23 03:09:44 +00004462- Added the future_builtins module, which contains hex() and oct().
4463 These are the PEP 3127 version of these functions, designed to be
4464 compatible with the hex() and oct() builtins from Python 3.0. They
4465 differ slightly in their output formats from the existing, unchanged
4466 Python 2.6 builtins. The expected usage of the future_builtins
4467 module is:
4468 from future_builtins import hex, oct
4469
Eric Smith7ef40bf2008-02-20 23:34:22 +00004470- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4471 exponents for exponents with absolute value < 100. Follows C99
4472 standard. This is a change on Windows, which would use 3 digits.
4473 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4474 so that any alterations it does to the resulting string will be
4475 available in stringlib/formatter.h (for float.__format__).
4476
Eric Smith5a3c1352008-02-19 13:21:56 +00004477- Implemented PEP 3101, Advanced String Formatting. This adds a new
4478 builtin format(); a format() method for str and unicode; a
4479 __format__() method to object, str, unicode, int, long, float, and
4480 datetime; the class string.Formatter; and the C API
4481 PyObject_Format().
4482
Georg Brandl3ee81df2008-05-17 18:14:43 +00004483- Fixed several potential crashes, all caused by specially crafted
4484 __del__ methods exploiting objects in temporarily inconsistent
4485 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004486
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004487- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004488 prevent a possible crash: an Abstract Base Class would try to access
4489 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004490
Georg Brandl3ee81df2008-05-17 18:14:43 +00004491- Fixed repr() and str() of complex numbers with infinity or nan as
4492 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004493
Georg Brandl3ee81df2008-05-17 18:14:43 +00004494- Clear all free lists during a gc.collect() of the highest generation

4496 memory to the OS earlier.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004498- Issue #2045: Fix an infinite recursion triggered when printing a
4499 subclass of collections.defaultdict, if its default_factory is set
4500 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004501
Christian Heimesf75dbef2008-02-08 00:11:31 +00004502- Fixed a minor memory leak in dictobject.c. The content of the free
4503 list was not freed on interpreter shutdown.
4504
Georg Brandl21e99f42010-03-07 15:23:59 +00004505- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004506 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004528- Patch #1473257: generator objects gain a gi_code attribute. This is
4529 the same object as the func_code attribute of the function that
4530 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004531
Georg Brandl3ee81df2008-05-17 18:14:43 +00004532- Issue #1920: "while 0" statements were completely removed by the
4533 compiler, even in the presence of an "else" clause, which is
4534 supposed to be run when the condition is false. Now the compiler
4535 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004536
Guido van Rossumeead05f2008-01-24 18:21:02 +00004537- A few crashers fixed: weakref_in_del.py (issue #1377858);
4538 loosing_dict_ref.py (issue #1303614, test67.py);
4539 borrowed_ref_[34].py (not in tracker).
4540
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004541- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004542 suppressed while an extension is loaded by calling SetErrorMode in
4543 dynload_win.c. The error is still reported properly.
4544
Georg Brandl3ee81df2008-05-17 18:14:43 +00004545- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004546 several extension methods and modules do not work without unicode
4547 support.
4548
Georg Brandl26543b12008-01-21 18:36:51 +00004549- Issue #1882: when compiling code from a string, encoding cookies in the

4553
Georg Brandl6caad7d2008-01-26 14:19:22 +00004554- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004555 added.
4556
Christian Heimesc94e2b52008-01-14 04:13:37 +00004557- sys.float_info / PyFloat_GetInfo: The floating point information
4558 object was converted from a dict to a specialized structseq object.
4559
Georg Brandl3ee81df2008-05-17 18:14:43 +00004560- Patch #1816: Added sys.flags structseq. It exposes the status of
4561 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004562
Georg Brandl3ee81df2008-05-17 18:14:43 +00004563- Objects/structseq.c: Implemented new structseq representation. The
4564 patch makes structseqs (e.g. the return value of os.stat) more
4565 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004566
Georg Brandl3ee81df2008-05-17 18:14:43 +00004567- Patch #1700288: added a type attribute cache that caches method
4568 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004569
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004570- Bug #1776: __import__() no longer accepts filenames on any platform.

Georg Brandlaed6c662008-01-07 17:25:53 +00004573- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4574
Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4576 envvar and sys.dont_write_bytecode attribute. All these can be set
4577 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004578
Georg Brandl3ee81df2008-05-17 18:14:43 +00004579- Improve some exception messages when Windows fails to load an
4580 extension module. Now we get for example '%1 is not a valid Win32
4581 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004588- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004589 and INF. float("nan"), float("inf") and float("-inf") now work on
4590 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004591
Georg Brandl3ee81df2008-05-17 18:14:43 +00004592- Compiler now generates simpler and faster code for dictionary
4593 literals. The oparg for BUILD_MAP now indicates an estimated
4594 dictionary size. There is a new opcode, STORE_MAP, for adding
4595 entries to the dictionary.

4625 file can now be directly executed by passing their name to the
4626 interpreter. The directory/zipfile is automatically inserted as the
4627 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004629- Issue #1265: Fix a problem with sys.settrace, if the tracing
4630 function uses a generator expression when at the same time the
4631 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004632
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004633- sets and frozensets now have an isdisjoint() method.
4634

4638
Georg Brandl21e99f42010-03-07 15:23:59 +00004639- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004640 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4641 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004642
Georg Brandl3ee81df2008-05-17 18:14:43 +00004643- Issue #1686386: Tuple's tp_repr did not take into account the
4644 possibility of having a self-referential tuple, which is possible
4645 from C code. Nor did object's tp_str consider that a type's tp_str
4646 could do something that could lead to an inifinite recursion.
4647 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4648 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004649
Georg Brandl3ee81df2008-05-17 18:14:43 +00004650- Issue #1164: It was possible to trigger deadlock when using the
4651 'print' statement to write to a file since the GIL was not released
4652 as needed. Now PyObject_Print() does the right thing along with
4653 various tp_print implementations of the built-in types and those in
4654 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004655
Georg Brandl3ee81df2008-05-17 18:14:43 +00004656- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00004662
Brett Cannon1e534b52007-09-07 04:18:30 +00004663- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004664 PyObject_Call() never calling back out to Python code to trigger
4665 recursion depth updates/checks. Required the creation of a static
4666 RuntimeError instance in case normalizing an exception put the
4667 recursion check value past its limit. Fixes crashers
4668 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004669

Neal Norwitz0ac60192007-05-27 04:08:54 +00004683- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004684 __*__ attributes. (Some already existed, e.g., __doc__ and
4685 __name__.)

4689
Georg Brandl2134e752007-05-21 20:34:16 +00004690- Patch #1686487: you can now pass any mapping after '**' in function
4691 calls.
4692
Collin Winter62903052007-05-18 23:11:24 +00004693- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004694 "except E as target:". This is to provide forwards compatibility
4695 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004702- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004703 setting a plain string, ie don't expand to single letter identifiers.
4704
Raymond Hettinger13936692007-04-11 18:40:58 +00004705- Request #1191699: Slices can now be pickled.

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004707- Request #1193128: str.translate() now allows a None argument for
4708 translations that only remove characters without re-mapping the
4709 remaining characters.
4710
Georg Brandl5cb76c12007-03-21 09:00:39 +00004711- Patch #1682205: a TypeError while unpacking an iterable is no longer

4715
Guido van Rossum143b5642007-03-23 04:58:42 +00004716- Bug #1683368: The object.__init__() and object.__new__() methods are
4717 now stricter in rejecting excess arguments. The only time when
4718 either allows excess arguments is when it is not overridden and the
4719 other one is. For backwards compatibility, when both are
4720 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004721 warning later). Also, type.__init__() insists on the same signature
4722 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004724- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4725 object to complex using its __complex__() method before falling back
4726 to the __float__() method. Therefore, the functions in the cmath
4727 module now can operate on objects that define a __complex__()
4728 method.

Georg Brandlaa2321b2007-03-07 00:40:28 +00004764- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00004834- Bug #1545497: when given an explicit base, int() did ignore NULs
4835 embedded in the string to convert.
4836
Georg Brandl846f73a2006-10-08 07:11:54 +00004837- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00004867- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004885 generator expressions (x for x, in ... ) works again. Fixing this
4886 problem required changing the .pyc magic number. This means that

Georg Brandl3ee81df2008-05-17 18:14:43 +00005276 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005317 AttributeError instead of an IOError when the server's response
5318 didn't contain a valid HTTP status line.

5350
Georg Brandl92a6bae2007-03-13 17:43:32 +00005351- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005352 are set for invalid interpolation sequences that would lead to
5353 errors on reading back those values.

5409 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00005802 time so that opening a database previously created with the DB_DUP
5803 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5804 opens. Specifically: dictionary assignment to a DB object will
5805 replace all values for a given key when the database allows
5806 duplicate values. DB users should use DB.put(k, v) when they want
5807 to store duplicates; not DB[k] = v.

5814 characters with ASCII value less than 32. Also, it correctly quotes
5815 dots only if they occur on a single line, as opposed to the previous
5816 behavior of quoting dots if they are the second character of any
5817 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005818
