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'.

Mark Dickinsone4b83e02010-06-05 12:14:43 +0000150 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
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.)
165
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000166- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

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.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001029- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001030 file position when calling `truncate()`. It would previously change the file
1031 position to the given argument, which goes against the tradition of

1035 class used to represent files stored inside an archive. The new
1036 implementation is significantly faster and can be wrapped in a
1037 ``io.BufferedReader`` object for more speedups. It also solves an issue
1038 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1127-----------------
1128
Georg Brandlba83f822010-03-14 09:50:54 +00001129- The ``__complex__()`` method is now looked up on the class of instances to
1130 make it consistent with other special methods.

1134
Mark Dickinson1b34d252010-01-01 17:27:30 +00001135- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001136 DeprecationWarning when passed a float argument where an integer was expected.
1137 These functions and methods now raise TypeError instead. The majority of the
1138 effects of this change are in the extension modules, but some core functions
1139 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1140 and many unicode/str methods.

1155 least on IEEE 754 platforms), and in particular does not depend on the
1156 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001305- Issue #3382: 'F' formatting for float and complex now convert the result to
1306 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1307 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001308
Georg Brandlba83f822010-03-14 09:50:54 +00001309- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1310 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001311
Georg Brandlba83f822010-03-14 09:50:54 +00001312- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1313 1e-100 used to raise OverflowError, but now gives the requested 120
1314 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001315

1321 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001322
Georg Brandlba83f822010-03-14 09:50:54 +00001323- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1324 decimal string that's guaranteed to round back to x under correct rounding
1325 (with round-half-to-even rounding mode). Previously it gave a string based on
1326 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1327 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1328 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001329
Georg Brandlba83f822010-03-14 09:50:54 +00001330- Issue #7117: On almost all platforms: float-to-string and string-to-float
1331 conversions within Python are now correctly rounded. Places these conversions
1332 occur include: str for floats and complex numbers; the float and complex
1333 constructors; old-style and new-style numeric formatting; serialization and
1334 deserialization of floats and complex numbers using marshal, pickle and json;
1335 parsing of float and imaginary literals in Python code; Decimal-to-float
1336 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001337
Georg Brandlba83f822010-03-14 09:50:54 +00001338 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1339 providing correctly-rounded strtod and dtoa C functions. This code is
1340 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1341 the C compiler. There may be a small number of platforms on which correct
1342 operation of this code cannot be guaranteed, so the code is not used: notably,
1343 this applies to platforms where the C double format is not IEEE 754 binary64,
1344 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1345 and Python's configure script is unable to determine how to change the FPU
1346 precision. On these platforms conversions use the platform strtod and dtoa,
1347 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001348
Georg Brandlba83f822010-03-14 09:50:54 +00001349- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1350 uses the correctly-rounded string <-> float conversions described above (when
1351 available), and so produces correctly rounded results that will display nicely
1352 under the float repr. There are two related small changes: (1) round now
1353 accepts any class with an ``__index__()`` method for its second argument (but
1354 no longer accepts floats for the second argument), and (2) an excessively
1355 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1356 raises an exception.

1359
Georg Brandlba83f822010-03-14 09:50:54 +00001360- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001498
Georg Brandlba83f822010-03-14 09:50:54 +00001499 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1500 (2) parsing of strings representing infinities and nans was locale aware; and
1501 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001503- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1504 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1505 but with at least one decimal point and with a default precision
1506 of 12. Previously, the behavior the same but with a default precision of 6.
1507 This more closely matches ``str()``, and reduces surprises when adding
1508 alignment flags to the empty presentation type. This also affects the new
1509 complex.__format__ in the same way.
1510
1511- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1512 classtype's, even if it was None. property now inserts the __doc__ into the
1513 subclass instance __dict__.

1583 internal representation of integers, for performance reasons. Base 2**30 is
1584 enabled by default on 64-bit machines. Add --enable-big-digits option to

2996 threads could return successfully while some Thread objects were still

3135-----------------
3136
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003137- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3138
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003139- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3140 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3141 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3142 ``printf`` function, whereas PyString_FromFormat has an independent
3143 implementation and uses "%zd" on all platforms for size_t values.
3144 This makes a difference on win64, where ``printf`` needs "%Id" to display
3145 64bit values.
3146
Benjamin Peterson97179b02008-09-09 20:55:01 +00003147- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3148 error.
3149
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003150- Issue #3777: long() applied to a float object now always return a long
3151 object; previously an int would be returned for small values. the __long__
3152 method is allowed to return either an int or a long, but the behaviour of
3153 float objects should not change to respect backward compatibility.
3154
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003155- Issue #3751: str.rpartition would perform a left-partition when called with
3156 a unicode argument.
3157
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003158- Issue #3683: Fix compilation when --without-threads is given.
3159
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003160- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003161 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003162 was correctly parsed but parsing of subsequent arguments failed.
3163
Vinay Sajip35e3b032008-09-01 14:33:59 +00003164- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003165 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3166 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3167 when given a tuple of classes as second argument, were looking up
3168 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3169 type object.
3170
Neal Norwitz18aa3882008-08-24 05:04:52 +00003171- Fix crashes on memory allocation failure found with failmalloc.
3172
3173- Fix memory leaks found with valgrind and update suppressions file.
3174
3175- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3176
3177- Fix problem using wrong name in decimal module reported by pychecker.
3178
Christian Heimes7d4c3172008-08-22 19:47:25 +00003179- Silenced another compiler warning about a used but not defined
3180 function 'stringlib_contains_obj'.

3183 ``__delslice__``.
3184
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003185- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3186 library targets in the Makefile.
3187
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003188- Issue #1204: The configure script now tests for additional libraries
3189 that may be required when linking against readline. This fixes issues
3190 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00003213- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003214 return a list or None rather than a custom object.

3240 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3241 for catch_warnings() also led to an improvement in the raising of a
3242 DeprecationWarning related to warnings.warn_explicit().
3243
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003244- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003308What's New in Python 2.6 beta 3?
3309================================
3310
Barry Warsaw07a4a382008-08-21 01:15:08 +00003311*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003312
3313Core and Builtins
3314-----------------
3315
Guido van Rossumf8402962008-08-20 15:01:50 +00003316- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3317 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3318 extensions do not automatically benefit from the class attribute
3319 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3320 to their tp_flags field if they care. This is a backwards
3321 compatibility feature; in 3.0, all types will use the cache by
3322 default.
3323
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003324- Keyword arguments can now follow starred arguments. (``f(a, *args,
3325 keyword=23)`` is now valid syntax.)
3326
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003327- ctypes function pointers that are COM methods have a boolean True
3328 value again.
3329
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003330- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3331 by denying s# to parse objects that have a releasebuffer procedure,
3332 and introducing s*.
3333
Georg Brandl1e13ea92008-08-11 09:07:59 +00003334- Issue #3537: Fix an assertion failure when an empty but presized dict
3335 object was stored in the freelist.
3336
Mark Dickinsonb6467572008-08-04 21:30:09 +00003337- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3338 ValueError consistently across platforms.
3339
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003340- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3341 (64bit Unix, for example), unichr() would truncate its argument and return
3342 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3343
Neal Norwitze7d8be82008-07-31 17:17:14 +00003344- Apply security patches from Apple.
3345
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003346- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3347 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3348
Antoine Pitrou92f82162008-07-25 22:22:08 +00003349- Issue #1819: function calls with several named parameters are now on
3350 average 35% faster (as measured by pybench).
3351
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003352- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3353 the python debugger steps into a class statement: the free variables (local
3354 variables defined in an outer scope) would be deleted from the outer scope.
3355
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003356- Issue #2620: Overflow checking when allocating or reallocating memory
3357 was not always being done properly in some python types and extension
3358 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3359 all been updated to perform better checks and places in the code that
3360 would previously leak memory on the error path when such an allocation
3361 failed have been fixed.

3365
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003366- Issue #3612: Added some missing basic types in ctypes.wintypes.
3367
Benjamin Petersone977ad42008-08-20 01:42:01 +00003368- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3369 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3370
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003371- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3372 version reported by these tools does not necessarily follow the python
3373 version numbering scheme, so the module is less strict when parsing it.
3374
Nick Coghlanf70385a2008-08-18 12:42:46 +00003375- Issue #2235: Added Py3k warnings for types which will become unhashable
3376 under the stricter __hash__ inheritance rules in 3.0. Several types
3377 which did not meet the rules for hash invariants and were already
3378 unhashable in 3.0 have now been explicitly flagged as unhashable in
3379 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3380 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3381
Brett Cannon88f801d2008-08-18 00:46:22 +00003382- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3383 imported into the module but exposed as part of the module's API.
3384
Brett Cannon7b96f072008-08-18 00:41:11 +00003385- Remove an unneeded import of abc.ABCMeta from 'inspect'.

3390
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003391- Issue #3575: Incremental decoder's decode function now takes bytearray
3392 by using 's*' instead of 't#'.
3393
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003394- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003395 fails unicode conversion on 2nd parameter. (windows only)
3396
Facundo Batista94f243a2008-08-17 03:38:39 +00003397- Issue 2464. urllib2 now supports a malformation in the URL received
3398 in a redirect.
3399

3429 to _sre.compile() will now be rejected. This should not affect anybody
3430 since the re.compile() function never generates invalid re-bytecode.

Antoine Pitroude781a42008-08-09 12:43:23 +00003451 asking for a specific length. This problem only affected files opened

3479 mode 0600 rather than 000 under Unix.
3480
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003481- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3495
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003496- Issue #643841: The language reference now provides more detailed

3508-----------------
3509
Georg Brandl3e483f62008-07-16 22:57:41 +00003510- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3511 its methods now allow for items objects that can be converted to
3512 an integer using operator.index().
3513
Mark Dickinson64b7e502008-07-16 09:40:03 +00003514- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3515 produced a ValueError instead of giving the correct float.
3516
Eric Smitha5fa5a22008-07-16 00:11:49 +00003517- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3518 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3519
Mark Dickinson7103aa42008-07-15 19:08:33 +00003520- Issue #3008: the float type has a new instance method 'float.hex'
3521 and a new class method 'float.fromhex' to convert floating-point
3522 numbers to and from hexadecimal strings, respectively.
3523
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003524- Issue #2235: __hash__ is once again inherited by default. To allow
3525 collections.Hashable to remain meaningful in the presence of the
3526 default hash implementation (object.__hash__), it is now possible
3527 to explicit block inheritance of hash by setting __hash__=None at
3528 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3529 level.
3530
Nick Coghlanb028f502008-07-13 14:52:36 +00003531- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3532 the parent module cannot be found while performing an absolute import.
3533 This means that an incorrectly defined __package__ attribute will
3534 now only prevent relative imports in that module rather than causing
3535 all imports from that module to fail.
3536
Nick Coghlan14ff9942008-07-08 14:21:42 +00003537- Issue #2517: Allow unicode messages in Exceptions again by correctly
3538 bypassing the instance dictionary when looking up __unicode__ on
3539 new-style classes.

3547 another thread's dictionary.
3548
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003549- Issue #3004: Minor change to slice.indices(): the start and stop
3550 arguments are now treated identically, making the behaviour easier
3551 to describe and understand. For example, slice(None, -10,
3552 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3553 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3554 10, -1).
3555
Georg Brandl278fc502008-07-19 12:46:12 +00003556- Issue #3219: Calling a function with repeated keyword arguments,
3557 f(a=2, a=23), would not cause a syntax error. This was a regression
3558 from 2.4 caused by the switch to the new compiler.

3568 api functions without holding the GIL, which could lead to a fatal
3569 error when they failed.
3570
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003571- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003596- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3597 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003598 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003599 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003615- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3617
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003618- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

4005
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004006- On MacOS X it is now possible to install the framework in 64-bit
4007 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004008 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004009
4010 This is controlled by the configure argument ``--with-universal-archs``:
4011
4012 - ``--with-universal-archs=all``: install 4-way universal
4013
4014 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4015
4016 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4017
4018 This option should be used in combination with ``--enable-universalsdk=``.
4019
4020 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 +00004070- Issue #1631171: Re-implement the 'warnings' module in C (the
4071 original Python code has been kept as backup). This will allow for
4072 using the 'warning's machinery in such places as the parser where
4073 use of pure Python code is not possible. Both the ``showarning()``
4074 and ``formatwarning()`` gain an optional 'line' argument which is
4075 not called by default for backwards-compatibility reasons. Setting
4076 ``warnings.showwarning()`` to an implementation that lacks support
4077 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004119- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004120 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004140- Issue #2550: The approach used by client/server code for obtaining
4141 ports to listen on in network-oriented tests has been refined in an
4142 effort to facilitate running multiple instances of the entire
4143 regression test suite in parallel without issue.
4144 test_support.bind_port() has been fixed such that it will always
4145 return a unique port -- which wasn't always the case with the
4146 previous implementation, especially if socket options had been set
4147 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4148 new implementation of bind_port() will actually raise an exception
4149 if it is passed an AF_INET/SOCK_STREAM socket with either the
4150 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4151 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4152 the socket it's been passed. This currently only applies to
4153 Windows. This option prevents any other sockets from binding to the
4154 host/port we've bound to, thus removing the possibility of the
4155 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4156 when a second SOCK_STREAM socket binds and accepts to a host/port
4157 that's already been bound by another socket. The optional preferred
4158 port parameter to bind_port() has been removed. Under no
4159 circumstances should tests be hard coding ports!
4160
4161 test_support.find_unused_port() has also been introduced, which will
4162 pass a temporary socket object to bind_port() in order to obtain an
4163 unused port. The temporary socket object is then closed and
4164 deleted, and the port is returned. This method should only be used
4165 for obtaining an unused port in order to pass to an external program
4166 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4167 a parameter to a server-oriented class that doesn't give you direct
4168 access to the underlying socket used.
4169
4170 Finally, test_support.HOST has been introduced, which should be used
4171 for the host argument of any relevant socket calls (i.e. bind and
4172 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004173
4174 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004175 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004176 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4177 test_asynchat and test_socket_ssl.
4178
Georg Brandl3ee81df2008-05-17 18:14:43 +00004179 It is now possible for multiple instances of the regression test
4180 suite to run in parallel without issue.

4447-----------------
4448
Fred Drakea8ee94b2008-03-01 02:45:07 +00004449- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004450 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00004455
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004456- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004457 issue 215555 for a discussion.
4458
Eric Smitha73fbe72008-02-23 03:09:44 +00004459- Added the future_builtins module, which contains hex() and oct().
4460 These are the PEP 3127 version of these functions, designed to be
4461 compatible with the hex() and oct() builtins from Python 3.0. They
4462 differ slightly in their output formats from the existing, unchanged
4463 Python 2.6 builtins. The expected usage of the future_builtins
4464 module is:
4465 from future_builtins import hex, oct
4466
Eric Smith7ef40bf2008-02-20 23:34:22 +00004467- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4468 exponents for exponents with absolute value < 100. Follows C99
4469 standard. This is a change on Windows, which would use 3 digits.
4470 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4471 so that any alterations it does to the resulting string will be
4472 available in stringlib/formatter.h (for float.__format__).
4473
Eric Smith5a3c1352008-02-19 13:21:56 +00004474- Implemented PEP 3101, Advanced String Formatting. This adds a new
4475 builtin format(); a format() method for str and unicode; a
4476 __format__() method to object, str, unicode, int, long, float, and
4477 datetime; the class string.Formatter; and the C API
4478 PyObject_Format().
4479
Georg Brandl3ee81df2008-05-17 18:14:43 +00004480- Fixed several potential crashes, all caused by specially crafted
4481 __del__ methods exploiting objects in temporarily inconsistent
4482 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004483
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004484- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485 prevent a possible crash: an Abstract Base Class would try to access
4486 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004487
Georg Brandl3ee81df2008-05-17 18:14:43 +00004488- Fixed repr() and str() of complex numbers with infinity or nan as
4489 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004490
Georg Brandl3ee81df2008-05-17 18:14:43 +00004491- Clear all free lists during a gc.collect() of the highest generation

4493 memory to the OS earlier.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004495- Issue #2045: Fix an infinite recursion triggered when printing a
4496 subclass of collections.defaultdict, if its default_factory is set
4497 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004498
Christian Heimesf75dbef2008-02-08 00:11:31 +00004499- Fixed a minor memory leak in dictobject.c. The content of the free
4500 list was not freed on interpreter shutdown.
4501
Georg Brandl21e99f42010-03-07 15:23:59 +00004502- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004503 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004525- Patch #1473257: generator objects gain a gi_code attribute. This is
4526 the same object as the func_code attribute of the function that
4527 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004528
Georg Brandl3ee81df2008-05-17 18:14:43 +00004529- Issue #1920: "while 0" statements were completely removed by the
4530 compiler, even in the presence of an "else" clause, which is
4531 supposed to be run when the condition is false. Now the compiler
4532 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004533
Guido van Rossumeead05f2008-01-24 18:21:02 +00004534- A few crashers fixed: weakref_in_del.py (issue #1377858);
4535 loosing_dict_ref.py (issue #1303614, test67.py);
4536 borrowed_ref_[34].py (not in tracker).
4537
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004538- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004539 suppressed while an extension is loaded by calling SetErrorMode in
4540 dynload_win.c. The error is still reported properly.
4541
Georg Brandl3ee81df2008-05-17 18:14:43 +00004542- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004543 several extension methods and modules do not work without unicode
4544 support.
4545
Georg Brandl26543b12008-01-21 18:36:51 +00004546- Issue #1882: when compiling code from a string, encoding cookies in the

4550
Georg Brandl6caad7d2008-01-26 14:19:22 +00004551- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004552 added.
4553
Christian Heimesc94e2b52008-01-14 04:13:37 +00004554- sys.float_info / PyFloat_GetInfo: The floating point information
4555 object was converted from a dict to a specialized structseq object.
4556
Georg Brandl3ee81df2008-05-17 18:14:43 +00004557- Patch #1816: Added sys.flags structseq. It exposes the status of
4558 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004559
Georg Brandl3ee81df2008-05-17 18:14:43 +00004560- Objects/structseq.c: Implemented new structseq representation. The
4561 patch makes structseqs (e.g. the return value of os.stat) more
4562 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004563
Georg Brandl3ee81df2008-05-17 18:14:43 +00004564- Patch #1700288: added a type attribute cache that caches method
4565 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004566
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004567- Bug #1776: __import__() no longer accepts filenames on any platform.

4573 envvar and sys.dont_write_bytecode attribute. All these can be set
4574 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004575
Georg Brandl3ee81df2008-05-17 18:14:43 +00004576- Improve some exception messages when Windows fails to load an
4577 extension module. Now we get for example '%1 is not a valid Win32
4578 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004585- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004586 and INF. float("nan"), float("inf") and float("-inf") now work on
4587 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004589- Compiler now generates simpler and faster code for dictionary
4590 literals. The oparg for BUILD_MAP now indicates an estimated
4591 dictionary size. There is a new opcode, STORE_MAP, for adding
4592 entries to the dictionary.

4622 file can now be directly executed by passing their name to the
4623 interpreter. The directory/zipfile is automatically inserted as the
4624 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004626- Issue #1265: Fix a problem with sys.settrace, if the tracing
4627 function uses a generator expression when at the same time the
4628 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004629
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004630- sets and frozensets now have an isdisjoint() method.

4635
Georg Brandl21e99f42010-03-07 15:23:59 +00004636- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004637 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4638 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004639
Georg Brandl3ee81df2008-05-17 18:14:43 +00004640- Issue #1686386: Tuple's tp_repr did not take into account the
4641 possibility of having a self-referential tuple, which is possible
4642 from C code. Nor did object's tp_str consider that a type's tp_str
4643 could do something that could lead to an inifinite recursion.
4644 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4645 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004646
Georg Brandl3ee81df2008-05-17 18:14:43 +00004647- Issue #1164: It was possible to trigger deadlock when using the
4648 'print' statement to write to a file since the GIL was not released
4649 as needed. Now PyObject_Print() does the right thing along with
4650 various tp_print implementations of the built-in types and those in
4651 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004652
Georg Brandl3ee81df2008-05-17 18:14:43 +00004653- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00004660- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004661 PyObject_Call() never calling back out to Python code to trigger
4662 recursion depth updates/checks. Required the creation of a static
4663 RuntimeError instance in case normalizing an exception put the
4664 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00004680- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004681 __*__ attributes. (Some already existed, e.g., __doc__ and
4682 __name__.)

4688 calls.
4689
Collin Winter62903052007-05-18 23:11:24 +00004690- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004691 "except E as target:". This is to provide forwards compatibility
4692 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004699- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004700 setting a plain string, ie don't expand to single letter identifiers.
4701
Raymond Hettinger13936692007-04-11 18:40:58 +00004702- Request #1191699: Slices can now be pickled.

4706 remaining characters.
4707
Georg Brandl5cb76c12007-03-21 09:00:39 +00004708- Patch #1682205: a TypeError while unpacking an iterable is no longer

4712
Guido van Rossum143b5642007-03-23 04:58:42 +00004713- Bug #1683368: The object.__init__() and object.__new__() methods are
4714 now stricter in rejecting excess arguments. The only time when
4715 either allows excess arguments is when it is not overridden and the
4716 other one is. For backwards compatibility, when both are
4717 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004718 warning later). Also, type.__init__() insists on the same signature
4719 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004721- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4722 object to complex using its __complex__() method before falling back
4723 to the __float__() method. Therefore, the functions in the cmath
4724 module now can operate on objects that define a __complex__()
4725 method.

Georg Brandlaa2321b2007-03-07 00:40:28 +00004761- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00004831- Bug #1545497: when given an explicit base, int() did ignore NULs
4832 embedded in the string to convert.
4833
Georg Brandl846f73a2006-10-08 07:11:54 +00004834- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00004864- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004882 generator expressions (x for x, in ... ) works again. Fixing this
4883 problem required changing the .pyc magic number. This means that
4884 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005273 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005314 AttributeError instead of an IOError when the server's response
5315 didn't contain a valid HTTP status line.

5347
Georg Brandl92a6bae2007-03-13 17:43:32 +00005348- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005349 are set for invalid interpolation sequences that would lead to
5350 errors on reading back those values.

5406 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00005799 time so that opening a database previously created with the DB_DUP
5800 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5801 opens. Specifically: dictionary assignment to a DB object will
5802 replace all values for a given key when the database allows
5803 duplicate values. DB users should use DB.put(k, v) when they want
5804 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005805

5811 characters with ASCII value less than 32. Also, it correctly quotes
5812 dots only if they occur on a single line, as opposed to the previous
5813 behavior of quoting dots if they are the second character of any
5814 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005815

6221 This lead to the deprecation of macostools.touched() as it relied
6222 solely on macfs and was a no-op under OS X.
