Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000146- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
147 start byte and the continuation byte(s) are now considered invalid, instead
148 of the number of bytes specified by the start byte.
149 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
150 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
151 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
152 Previous versions returned a single u'\ufffd'.

Mark Dickinsone4b83e02010-06-05 12:14:43 +0000155 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
156 arises from the "Overriding __eq__ blocks inheritance ..." warning
157 when turned into an exception: in this case the exception simply
158 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000160- Issue #8748: Fix two issues with comparisons between complex and integer
161 objects. (1) The comparison could incorrectly return True in some cases
162 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
163 (2) The comparison raised an OverflowError for large integers, leading
164 to unpredictable exceptions when combining integers and complex objects
165 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +0000167- Issue #5211: Implicit coercion for the complex type is now completely
168 removed. (Coercion for arithmetic operations was already removed in 2.7
169 alpha 4, but coercion for rich comparisons was accidentally left in.)

Georg Brandlfee0f442010-05-22 21:26:21 +0000547- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
548 with a non-empty format string. This is an effort to future-proof user
549 code. If a derived class does not currently implement __format__ but later
550 adds its own __format__, it would most likely break user code that had
551 supplied a format string. This will be changed to a DeprecationWaring in
552 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +0000624- Comparisons using one of <, <=, >, >= between a complex instance and a
625 Fractions instance now raise TypeError instead of returning True/False. This
626 makes Fraction <=> complex comparisons consistent with int <=> complex, float
627 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001040 file position when calling `truncate()`. It would previously change the file
1041 position to the given argument, which goes against the tradition of

1045 class used to represent files stored inside an archive. The new
1046 implementation is significantly faster and can be wrapped in a
1047 ``io.BufferedReader`` object for more speedups. It also solves an issue
1048 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1137-----------------
1138
Georg Brandlba83f822010-03-14 09:50:54 +00001139- The ``__complex__()`` method is now looked up on the class of instances to
1140 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001142- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1143 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1144
Mark Dickinson1b34d252010-01-01 17:27:30 +00001145- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001146 DeprecationWarning when passed a float argument where an integer was expected.
1147 These functions and methods now raise TypeError instead. The majority of the
1148 effects of this change are in the extension modules, but some core functions
1149 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1150 and many unicode/str methods.

1164 of integers: the result of a/b is now correctly rounded for ints a and b (at
1165 least on IEEE 754 platforms), and in particular does not depend on the
1166 internal representation of a long.

1174
Georg Brandlba83f822010-03-14 09:50:54 +00001175 These executables now work properly with the arch(1) command: ``arch -ppc
1176 python`` will start a universal binary version of python in PPC mode (unlike

1267 TypeError. For the 'L' format code (which previously had no warning) there is
1268 now a DeprecationWarning.

1317 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001318
Georg Brandlba83f822010-03-14 09:50:54 +00001319- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1320 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001321

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001332
Georg Brandlba83f822010-03-14 09:50:54 +00001333- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1334 decimal string that's guaranteed to round back to x under correct rounding
1335 (with round-half-to-even rounding mode). Previously it gave a string based on
1336 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1337 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1338 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001339
Georg Brandlba83f822010-03-14 09:50:54 +00001340- Issue #7117: On almost all platforms: float-to-string and string-to-float
1341 conversions within Python are now correctly rounded. Places these conversions
1342 occur include: str for floats and complex numbers; the float and complex
1343 constructors; old-style and new-style numeric formatting; serialization and
1344 deserialization of floats and complex numbers using marshal, pickle and json;
1345 parsing of float and imaginary literals in Python code; Decimal-to-float
1346 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001347
Georg Brandlba83f822010-03-14 09:50:54 +00001348 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1349 providing correctly-rounded strtod and dtoa C functions. This code is
1350 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1351 the C compiler. There may be a small number of platforms on which correct
1352 operation of this code cannot be guaranteed, so the code is not used: notably,
1353 this applies to platforms where the C double format is not IEEE 754 binary64,
1354 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1355 and Python's configure script is unable to determine how to change the FPU
1356 precision. On these platforms conversions use the platform strtod and dtoa,
1357 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001358
Georg Brandlba83f822010-03-14 09:50:54 +00001359- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1360 uses the correctly-rounded string <-> float conversions described above (when
1361 available), and so produces correctly rounded results that will display nicely
1362 under the float repr. There are two related small changes: (1) round now
1363 accepts any class with an ``__index__()`` method for its second argument (but
1364 no longer accepts floats for the second argument), and (2) an excessively
1365 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1366 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001508
Georg Brandlba83f822010-03-14 09:50:54 +00001509 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1510 (2) parsing of strings representing infinities and nans was locale aware; and
1511 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001513- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1514 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1515 but with at least one decimal point and with a default precision
1516 of 12. Previously, the behavior the same but with a default precision of 6.
1517 This more closely matches ``str()``, and reduces surprises when adding
1518 alignment flags to the empty presentation type. This also affects the new
1519 complex.__format__ in the same way.
1520
1521- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

1750 eventual KeyError would always report the empty ``frozenset()`` as the missing

1772 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandl2bd92a52009-10-11 21:10:07 +00003127- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00003128 AttributeError instead of RuntimeError, depending in which C API call
3129 exactly the recursion limit is exceeded. Consequently, both exception types
3130 are caught and silenced.

3146
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003147- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3148
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003149- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3150 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3151 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3152 ``printf`` function, whereas PyString_FromFormat has an independent
3153 implementation and uses "%zd" on all platforms for size_t values.
3154 This makes a difference on win64, where ``printf`` needs "%Id" to display
3155 64bit values.
3156
Benjamin Peterson97179b02008-09-09 20:55:01 +00003157- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3158 error.
3159
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003160- Issue #3777: long() applied to a float object now always return a long
3161 object; previously an int would be returned for small values. the __long__
3162 method is allowed to return either an int or a long, but the behaviour of
3163 float objects should not change to respect backward compatibility.
3164
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003165- Issue #3751: str.rpartition would perform a left-partition when called with
3166 a unicode argument.
3167
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003168- Issue #3683: Fix compilation when --without-threads is given.
3169
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003170- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003171 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003172 was correctly parsed but parsing of subsequent arguments failed.
3173
Vinay Sajip35e3b032008-09-01 14:33:59 +00003174- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003175 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3176 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3177 when given a tuple of classes as second argument, were looking up
3178 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3179 type object.
3180
Neal Norwitz18aa3882008-08-24 05:04:52 +00003181- Fix crashes on memory allocation failure found with failmalloc.
3182
3183- Fix memory leaks found with valgrind and update suppressions file.
3184
3185- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3186
3187- Fix problem using wrong name in decimal module reported by pychecker.
3188
Christian Heimes7d4c3172008-08-22 19:47:25 +00003189- Silenced another compiler warning about a used but not defined
3190 function 'stringlib_contains_obj'.
3191

3193 ``__delslice__``.
3194
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003195- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3196 library targets in the Makefile.
3197
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003198- Issue #1204: The configure script now tests for additional libraries
3199 that may be required when linking against readline. This fixes issues
3200 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

3222
Nick Coghland2e09382008-09-11 12:11:06 +00003223- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003224 return a list or None rather than a custom object.
3225
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003226- Issue #1638033: Cookie.Morsel gained the httponly attribute.

3250 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3251 for catch_warnings() also led to an improvement in the raising of a
3252 DeprecationWarning related to warnings.warn_explicit().
3253
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003254- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003322
3323Core and Builtins
3324-----------------
3325
Guido van Rossumf8402962008-08-20 15:01:50 +00003326- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3327 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3328 extensions do not automatically benefit from the class attribute
3329 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3330 to their tp_flags field if they care. This is a backwards
3331 compatibility feature; in 3.0, all types will use the cache by
3332 default.
3333
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003334- Keyword arguments can now follow starred arguments. (``f(a, *args,
3335 keyword=23)`` is now valid syntax.)
3336
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003337- ctypes function pointers that are COM methods have a boolean True
3338 value again.
3339
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003340- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3341 by denying s# to parse objects that have a releasebuffer procedure,
3342 and introducing s*.
3343
Georg Brandl1e13ea92008-08-11 09:07:59 +00003344- Issue #3537: Fix an assertion failure when an empty but presized dict
3345 object was stored in the freelist.
3346
Mark Dickinsonb6467572008-08-04 21:30:09 +00003347- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3348 ValueError consistently across platforms.
3349
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003350- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3351 (64bit Unix, for example), unichr() would truncate its argument and return
3352 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3353
Neal Norwitze7d8be82008-07-31 17:17:14 +00003354- Apply security patches from Apple.
3355
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003356- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3357 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3358
Antoine Pitrou92f82162008-07-25 22:22:08 +00003359- Issue #1819: function calls with several named parameters are now on
3360 average 35% faster (as measured by pybench).
3361
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003362- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3363 the python debugger steps into a class statement: the free variables (local
3364 variables defined in an outer scope) would be deleted from the outer scope.
3365
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003366- Issue #2620: Overflow checking when allocating or reallocating memory
3367 was not always being done properly in some python types and extension
3368 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3369 all been updated to perform better checks and places in the code that
3370 would previously leak memory on the error path when such an allocation
3371 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003376- Issue #3612: Added some missing basic types in ctypes.wintypes.
3377
Benjamin Petersone977ad42008-08-20 01:42:01 +00003378- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3379 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3380
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003381- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3382 version reported by these tools does not necessarily follow the python
3383 version numbering scheme, so the module is less strict when parsing it.
3384
Nick Coghlanf70385a2008-08-18 12:42:46 +00003385- Issue #2235: Added Py3k warnings for types which will become unhashable
3386 under the stricter __hash__ inheritance rules in 3.0. Several types
3387 which did not meet the rules for hash invariants and were already
3388 unhashable in 3.0 have now been explicitly flagged as unhashable in
3389 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3390 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3391
Brett Cannon88f801d2008-08-18 00:46:22 +00003392- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3393 imported into the module but exposed as part of the module's API.
3394
Brett Cannon7b96f072008-08-18 00:41:11 +00003395- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3396
Brett Cannon46225e72008-08-18 00:36:52 +00003397- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

3505
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003506- Issue #643841: The language reference now provides more detailed

3518-----------------
3519
Georg Brandl3e483f62008-07-16 22:57:41 +00003520- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3521 its methods now allow for items objects that can be converted to
3522 an integer using operator.index().
3523
Mark Dickinson64b7e502008-07-16 09:40:03 +00003524- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3525 produced a ValueError instead of giving the correct float.
3526
Eric Smitha5fa5a22008-07-16 00:11:49 +00003527- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3528 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3529
Mark Dickinson7103aa42008-07-15 19:08:33 +00003530- Issue #3008: the float type has a new instance method 'float.hex'
3531 and a new class method 'float.fromhex' to convert floating-point
3532 numbers to and from hexadecimal strings, respectively.
3533
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003534- Issue #2235: __hash__ is once again inherited by default. To allow
3535 collections.Hashable to remain meaningful in the presence of the
3536 default hash implementation (object.__hash__), it is now possible
3537 to explicit block inheritance of hash by setting __hash__=None at
3538 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3539 level.
3540
Nick Coghlanb028f502008-07-13 14:52:36 +00003541- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3542 the parent module cannot be found while performing an absolute import.
3543 This means that an incorrectly defined __package__ attribute will
3544 now only prevent relative imports in that module rather than causing
3545 all imports from that module to fail.
3546
Nick Coghlan14ff9942008-07-08 14:21:42 +00003547- Issue #2517: Allow unicode messages in Exceptions again by correctly

3557 another thread's dictionary.
3558
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003559- Issue #3004: Minor change to slice.indices(): the start and stop
3560 arguments are now treated identically, making the behaviour easier
3561 to describe and understand. For example, slice(None, -10,
3562 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3563 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3564 10, -1).
3565
Georg Brandl278fc502008-07-19 12:46:12 +00003566- Issue #3219: Calling a function with repeated keyword arguments,
3567 f(a=2, a=23), would not cause a syntax error. This was a regression
3568 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003606- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3607 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003608 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003609 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003625- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004016- On MacOS X it is now possible to install the framework in 64-bit
4017 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004018 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004019
4020 This is controlled by the configure argument ``--with-universal-archs``:
4021
4022 - ``--with-universal-archs=all``: install 4-way universal
4023
4024 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4025
4026 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4027
4028 This option should be used in combination with ``--enable-universalsdk=``.
4029
4030 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 +00004080- Issue #1631171: Re-implement the 'warnings' module in C (the
4081 original Python code has been kept as backup). This will allow for
4082 using the 'warning's machinery in such places as the parser where
4083 use of pure Python code is not possible. Both the ``showarning()``
4084 and ``formatwarning()`` gain an optional 'line' argument which is
4085 not called by default for backwards-compatibility reasons. Setting
4086 ``warnings.showwarning()`` to an implementation that lacks support
4087 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004150- Issue #2550: The approach used by client/server code for obtaining
4151 ports to listen on in network-oriented tests has been refined in an
4152 effort to facilitate running multiple instances of the entire
4153 regression test suite in parallel without issue.
4154 test_support.bind_port() has been fixed such that it will always
4155 return a unique port -- which wasn't always the case with the
4156 previous implementation, especially if socket options had been set
4157 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4158 new implementation of bind_port() will actually raise an exception
4159 if it is passed an AF_INET/SOCK_STREAM socket with either the
4160 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4161 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4162 the socket it's been passed. This currently only applies to
4163 Windows. This option prevents any other sockets from binding to the
4164 host/port we've bound to, thus removing the possibility of the
4165 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4166 when a second SOCK_STREAM socket binds and accepts to a host/port
4167 that's already been bound by another socket. The optional preferred
4168 port parameter to bind_port() has been removed. Under no
4169 circumstances should tests be hard coding ports!
4170
4171 test_support.find_unused_port() has also been introduced, which will
4172 pass a temporary socket object to bind_port() in order to obtain an
4173 unused port. The temporary socket object is then closed and
4174 deleted, and the port is returned. This method should only be used
4175 for obtaining an unused port in order to pass to an external program
4176 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4177 a parameter to a server-oriented class that doesn't give you direct
4178 access to the underlying socket used.
4179
4180 Finally, test_support.HOST has been introduced, which should be used
4181 for the host argument of any relevant socket calls (i.e. bind and
4182 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004183
4184 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004186 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4187 test_asynchat and test_socket_ssl.
4188
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189 It is now possible for multiple instances of the regression test
4190 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004245 \Uxxxxxxxx did not accept values outside the Basic Multilingual
4246 Plane. This affected raw unicode literals and the
4247 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
4248 this case, like normal unicode literals and the 'unicode-escape'
4249 codec.

4458
Fred Drakea8ee94b2008-03-01 02:45:07 +00004459- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004460 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00004465
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004466- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004467 issue 215555 for a discussion.
4468
Eric Smitha73fbe72008-02-23 03:09:44 +00004469- Added the future_builtins module, which contains hex() and oct().
4470 These are the PEP 3127 version of these functions, designed to be
4471 compatible with the hex() and oct() builtins from Python 3.0. They
4472 differ slightly in their output formats from the existing, unchanged
4473 Python 2.6 builtins. The expected usage of the future_builtins
4474 module is:
4475 from future_builtins import hex, oct
4476
Eric Smith7ef40bf2008-02-20 23:34:22 +00004477- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4478 exponents for exponents with absolute value < 100. Follows C99
4479 standard. This is a change on Windows, which would use 3 digits.
4480 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4481 so that any alterations it does to the resulting string will be
4482 available in stringlib/formatter.h (for float.__format__).
4483
Eric Smith5a3c1352008-02-19 13:21:56 +00004484- Implemented PEP 3101, Advanced String Formatting. This adds a new
4485 builtin format(); a format() method for str and unicode; a
4486 __format__() method to object, str, unicode, int, long, float, and
4487 datetime; the class string.Formatter; and the C API
4488 PyObject_Format().
4489
Georg Brandl3ee81df2008-05-17 18:14:43 +00004490- Fixed several potential crashes, all caused by specially crafted
4491 __del__ methods exploiting objects in temporarily inconsistent
4492 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004501- Clear all free lists during a gc.collect() of the highest generation
4502 in order to allow pymalloc to free more arenas. Python may give back
4503 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004504
Georg Brandl3ee81df2008-05-17 18:14:43 +00004505- Issue #2045: Fix an infinite recursion triggered when printing a
4506 subclass of collections.defaultdict, if its default_factory is set
4507 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004508
Christian Heimesf75dbef2008-02-08 00:11:31 +00004509- Fixed a minor memory leak in dictobject.c. The content of the free
4510 list was not freed on interpreter shutdown.
4511
Georg Brandl21e99f42010-03-07 15:23:59 +00004512- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004513 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004514
Georg Brandl3ee81df2008-05-17 18:14:43 +00004515- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4516 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004519- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4520 calls. Python expected the return type int but the fork familie
4521 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004522
Georg Brandl3ee81df2008-05-17 18:14:43 +00004523- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4524 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004535- Patch #1473257: generator objects gain a gi_code attribute. This is
4536 the same object as the func_code attribute of the function that
4537 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004538
Georg Brandl3ee81df2008-05-17 18:14:43 +00004539- Issue #1920: "while 0" statements were completely removed by the
4540 compiler, even in the presence of an "else" clause, which is
4541 supposed to be run when the condition is false. Now the compiler
4542 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004543
Guido van Rossumeead05f2008-01-24 18:21:02 +00004544- A few crashers fixed: weakref_in_del.py (issue #1377858);
4545 loosing_dict_ref.py (issue #1303614, test67.py);
4546 borrowed_ref_[34].py (not in tracker).
4547
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004548- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004549 suppressed while an extension is loaded by calling SetErrorMode in
4550 dynload_win.c. The error is still reported properly.
4551
Georg Brandl3ee81df2008-05-17 18:14:43 +00004552- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004553 several extension methods and modules do not work without unicode
4554 support.
4555
Georg Brandl26543b12008-01-21 18:36:51 +00004556- Issue #1882: when compiling code from a string, encoding cookies in the

4560
Georg Brandl6caad7d2008-01-26 14:19:22 +00004561- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004562 added.
4563
Christian Heimesc94e2b52008-01-14 04:13:37 +00004564- sys.float_info / PyFloat_GetInfo: The floating point information
4565 object was converted from a dict to a specialized structseq object.
4566
Georg Brandl3ee81df2008-05-17 18:14:43 +00004567- Patch #1816: Added sys.flags structseq. It exposes the status of
4568 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004569
Georg Brandl3ee81df2008-05-17 18:14:43 +00004570- Objects/structseq.c: Implemented new structseq representation. The
4571 patch makes structseqs (e.g. the return value of os.stat) more
4572 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004573
Georg Brandl3ee81df2008-05-17 18:14:43 +00004574- Patch #1700288: added a type attribute cache that caches method
4575 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004576
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004577- Bug #1776: __import__() no longer accepts filenames on any platform.
4578 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00004580- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4581
Georg Brandl3ee81df2008-05-17 18:14:43 +00004582- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4583 envvar and sys.dont_write_bytecode attribute. All these can be set
4584 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004585
Georg Brandl3ee81df2008-05-17 18:14:43 +00004586- Improve some exception messages when Windows fails to load an
4587 extension module. Now we get for example '%1 is not a valid Win32
4588 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004595- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004596 and INF. float("nan"), float("inf") and float("-inf") now work on
4597 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004598
Georg Brandl3ee81df2008-05-17 18:14:43 +00004599- Compiler now generates simpler and faster code for dictionary
4600 literals. The oparg for BUILD_MAP now indicates an estimated
4601 dictionary size. There is a new opcode, STORE_MAP, for adding
4602 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004631- Patch #1739468: Directories and zipfiles containing a __main__.py
4632 file can now be directly executed by passing their name to the
4633 interpreter. The directory/zipfile is automatically inserted as the
4634 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004635
Georg Brandl3ee81df2008-05-17 18:14:43 +00004636- Issue #1265: Fix a problem with sys.settrace, if the tracing
4637 function uses a generator expression when at the same time the
4638 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004639
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004640- sets and frozensets now have an isdisjoint() method.
4641
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004642- optimize the performance of builtin.sum().
4643

4645
Georg Brandl21e99f42010-03-07 15:23:59 +00004646- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004647 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4648 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004649
Georg Brandl3ee81df2008-05-17 18:14:43 +00004650- Issue #1686386: Tuple's tp_repr did not take into account the
4651 possibility of having a self-referential tuple, which is possible
4652 from C code. Nor did object's tp_str consider that a type's tp_str
4653 could do something that could lead to an inifinite recursion.
4654 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4655 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004656
Georg Brandl3ee81df2008-05-17 18:14:43 +00004657- Issue #1164: It was possible to trigger deadlock when using the
4658 'print' statement to write to a file since the GIL was not released
4659 as needed. Now PyObject_Print() does the right thing along with
4660 various tp_print implementations of the built-in types and those in
4661 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004662
Georg Brandl3ee81df2008-05-17 18:14:43 +00004663- Issue #1147: Exceptions were directly allowing string exceptions in
4664 their throw() method even though string exceptions no longer
4665 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004666
Georg Brandl3ee81df2008-05-17 18:14:43 +00004667- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00004669
Brett Cannon1e534b52007-09-07 04:18:30 +00004670- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004671 PyObject_Call() never calling back out to Python code to trigger
4672 recursion depth updates/checks. Required the creation of a static
4673 RuntimeError instance in case normalizing an exception put the
4674 recursion check value past its limit. Fixes crashers
4675 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004676

Neal Norwitz0ac60192007-05-27 04:08:54 +00004690- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004691 __*__ attributes. (Some already existed, e.g., __doc__ and
4692 __name__.)

4696
Georg Brandl2134e752007-05-21 20:34:16 +00004697- Patch #1686487: you can now pass any mapping after '**' in function
4698 calls.
4699
Collin Winter62903052007-05-18 23:11:24 +00004700- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004701 "except E as target:". This is to provide forwards compatibility
4702 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004709- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004710 setting a plain string, ie don't expand to single letter identifiers.
4711
Raymond Hettinger13936692007-04-11 18:40:58 +00004712- Request #1191699: Slices can now be pickled.
4713
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004714- Request #1193128: str.translate() now allows a None argument for

4716 remaining characters.
4717
Georg Brandl5cb76c12007-03-21 09:00:39 +00004718- Patch #1682205: a TypeError while unpacking an iterable is no longer

4722
Guido van Rossum143b5642007-03-23 04:58:42 +00004723- Bug #1683368: The object.__init__() and object.__new__() methods are
4724 now stricter in rejecting excess arguments. The only time when
4725 either allows excess arguments is when it is not overridden and the
4726 other one is. For backwards compatibility, when both are
4727 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004728 warning later). Also, type.__init__() insists on the same signature

Georg Brandl3ee81df2008-05-17 18:14:43 +00004731- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4732 object to complex using its __complex__() method before falling back
4733 to the __float__() method. Therefore, the functions in the cmath
4734 module now can operate on objects that define a __complex__()
4735 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004757 its argument, if it exists. If not, it will work like before. This
4758 allows customizing the output of dir() in the presence of a
4759 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00004771- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00004841- Bug #1545497: when given an explicit base, int() did ignore NULs
4842 embedded in the string to convert.
4843
Georg Brandl846f73a2006-10-08 07:11:54 +00004844- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004892 generator expressions (x for x, in ... ) works again. Fixing this
4893 problem required changing the .pyc magic number. This means that
4894 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005701- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5702 with RFC 3207 and forgets any knowledge obtained from the server not
5703 obtained from the TLS negotiation itself. Patch contributed by Bill
5704 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005705
Georg Brandl3ee81df2008-05-17 18:14:43 +00005706- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005707 that the SMTP.starttls() caller no longer needs to call ehlo()
5708 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005709 does not claim to support starttls. Adds the
5710 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5711 Fenner.

5791 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5792 silently miscode subclasses of those types. Now, it raises a
5793 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005794

Georg Brandl3ee81df2008-05-17 18:14:43 +00005809 time so that opening a database previously created with the DB_DUP
5810 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5811 opens. Specifically: dictionary assignment to a DB object will
5812 replace all values for a given key when the database allows
5813 duplicate values. DB users should use DB.put(k, v) when they want
5814 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005815

5821 characters with ASCII value less than 32. Also, it correctly quotes
5822 dots only if they occur on a single line, as opposed to the previous
5823 behavior of quoting dots if they are the second character of any
5824 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005825
