Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000155- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
156 start byte and the continuation byte(s) are now considered invalid, instead
157 of the number of bytes specified by the start byte.
158 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
159 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
160 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
161 Previous versions returned a single u'\ufffd'.

165 arises from the "Overriding __eq__ blocks inheritance ..." warning

167 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000169- Issue #8748: Fix two issues with comparisons between complex and integer
170 objects. (1) The comparison could incorrectly return True in some cases
171 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
172 (2) The comparison raised an OverflowError for large integers, leading
173 to unpredictable exceptions when combining integers and complex objects
174 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +0000176- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +0000313- Issue #1533: Fix inconsistency in range function argument processing: any
314 non-float non-integer argument is now converted to an integer (if possible)
315 using its __int__ method. Previously, only small arguments were treated this
316 way; larger arguments (those whose __int__ was outside the range of a C long)
317 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +0000325 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +0000326 benefit compared to the dynamic memory allocation fallback. Patch by

Georg Brandlfee0f442010-05-22 21:26:21 +0000367- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
368 operation raises multiple signals and more than one of those signals is
369 trapped, the specification determines the order in which the signals should be
370 handled. In many cases this order wasn't being followed, leading to the wrong
371 Python exception being raised.

557 with a non-empty format string. This is an effort to future-proof user
558 code. If a derived class does not currently implement __format__ but later
559 adds its own __format__, it would most likely break user code that had
560 supplied a format string. This will be changed to a DeprecationWaring in
561 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00001049 file position when calling `truncate()`. It would previously change the file
1050 position to the given argument, which goes against the tradition of

1054 class used to represent files stored inside an archive. The new
1055 implementation is significantly faster and can be wrapped in a

1057 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1146-----------------
1147
Georg Brandlba83f822010-03-14 09:50:54 +00001148- The ``__complex__()`` method is now looked up on the class of instances to
1149 make it consistent with other special methods.

1153
Mark Dickinson1b34d252010-01-01 17:27:30 +00001154- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001155 DeprecationWarning when passed a float argument where an integer was expected.
1156 These functions and methods now raise TypeError instead. The majority of the
1157 effects of this change are in the extension modules, but some core functions
1158 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1159 and many unicode/str methods.

1174 least on IEEE 754 platforms), and in particular does not depend on the
1175 internal representation of a long.

1183
Georg Brandlba83f822010-03-14 09:50:54 +00001184 These executables now work properly with the arch(1) command: ``arch -ppc
1185 python`` will start a universal binary version of python in PPC mode (unlike

1277 now a DeprecationWarning.

1326 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001327

1329 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001341
Georg Brandlba83f822010-03-14 09:50:54 +00001342- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1343 decimal string that's guaranteed to round back to x under correct rounding
1344 (with round-half-to-even rounding mode). Previously it gave a string based on
1345 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1346 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1347 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001348
Georg Brandlba83f822010-03-14 09:50:54 +00001349- Issue #7117: On almost all platforms: float-to-string and string-to-float
1350 conversions within Python are now correctly rounded. Places these conversions
1351 occur include: str for floats and complex numbers; the float and complex
1352 constructors; old-style and new-style numeric formatting; serialization and
1353 deserialization of floats and complex numbers using marshal, pickle and json;
1354 parsing of float and imaginary literals in Python code; Decimal-to-float
1355 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001356
Georg Brandlba83f822010-03-14 09:50:54 +00001357 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1358 providing correctly-rounded strtod and dtoa C functions. This code is
1359 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1360 the C compiler. There may be a small number of platforms on which correct
1361 operation of this code cannot be guaranteed, so the code is not used: notably,
1362 this applies to platforms where the C double format is not IEEE 754 binary64,
1363 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1364 and Python's configure script is unable to determine how to change the FPU
1365 precision. On these platforms conversions use the platform strtod and dtoa,
1366 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001367
Georg Brandlba83f822010-03-14 09:50:54 +00001368- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1369 uses the correctly-rounded string <-> float conversions described above (when
1370 available), and so produces correctly rounded results that will display nicely
1371 under the float repr. There are two related small changes: (1) round now
1372 accepts any class with an ``__index__()`` method for its second argument (but
1373 no longer accepts floats for the second argument), and (2) an excessively
1374 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1375 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001517
Georg Brandlba83f822010-03-14 09:50:54 +00001518 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1519 (2) parsing of strings representing infinities and nans was locale aware; and
1520 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001522- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1523 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1524 but with at least one decimal point and with a default precision
1525 of 12. Previously, the behavior the same but with a default precision of 6.
1526 This more closely matches ``str()``, and reduces surprises when adding
1527 alignment flags to the empty presentation type. This also affects the new
1528 complex.__format__ in the same way.
1529
1530- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

1781 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00003137 AttributeError instead of RuntimeError, depending in which C API call
3138 exactly the recursion limit is exceeded. Consequently, both exception types
3139 are caught and silenced.

3155
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003156- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3157
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003158- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3159 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3160 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3161 ``printf`` function, whereas PyString_FromFormat has an independent
3162 implementation and uses "%zd" on all platforms for size_t values.
3163 This makes a difference on win64, where ``printf`` needs "%Id" to display
3164 64bit values.
3165
Benjamin Peterson97179b02008-09-09 20:55:01 +00003166- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3167 error.
3168
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003169- Issue #3777: long() applied to a float object now always return a long
3170 object; previously an int would be returned for small values. the __long__
3171 method is allowed to return either an int or a long, but the behaviour of
3172 float objects should not change to respect backward compatibility.
3173
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003174- Issue #3751: str.rpartition would perform a left-partition when called with
3175 a unicode argument.
3176
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003177- Issue #3683: Fix compilation when --without-threads is given.
3178
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003179- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003180 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003181 was correctly parsed but parsing of subsequent arguments failed.
3182
Vinay Sajip35e3b032008-09-01 14:33:59 +00003183- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003184 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3185 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3186 when given a tuple of classes as second argument, were looking up
3187 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3188 type object.
3189
Neal Norwitz18aa3882008-08-24 05:04:52 +00003190- Fix crashes on memory allocation failure found with failmalloc.
3191
3192- Fix memory leaks found with valgrind and update suppressions file.
3193
3194- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3195
3196- Fix problem using wrong name in decimal module reported by pychecker.
3197
Christian Heimes7d4c3172008-08-22 19:47:25 +00003198- Silenced another compiler warning about a used but not defined
3199 function 'stringlib_contains_obj'.
3200

3202 ``__delslice__``.
3203
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003204- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3205 library targets in the Makefile.
3206
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003207- Issue #1204: The configure script now tests for additional libraries
3208 that may be required when linking against readline. This fixes issues
3209 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

3231
Nick Coghland2e09382008-09-11 12:11:06 +00003232- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003233 return a list or None rather than a custom object.
3234
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003235- Issue #1638033: Cookie.Morsel gained the httponly attribute.

3259 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3260 for catch_warnings() also led to an improvement in the raising of a
3261 DeprecationWarning related to warnings.warn_explicit().
3262
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003263- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003331
3332Core and Builtins
3333-----------------
3334
Guido van Rossumf8402962008-08-20 15:01:50 +00003335- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3336 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3337 extensions do not automatically benefit from the class attribute
3338 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3339 to their tp_flags field if they care. This is a backwards
3340 compatibility feature; in 3.0, all types will use the cache by
3341 default.
3342
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003343- Keyword arguments can now follow starred arguments. (``f(a, *args,
3344 keyword=23)`` is now valid syntax.)
3345
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003346- ctypes function pointers that are COM methods have a boolean True
3347 value again.
3348
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003349- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3350 by denying s# to parse objects that have a releasebuffer procedure,
3351 and introducing s*.
3352
Georg Brandl1e13ea92008-08-11 09:07:59 +00003353- Issue #3537: Fix an assertion failure when an empty but presized dict
3354 object was stored in the freelist.
3355
Mark Dickinsonb6467572008-08-04 21:30:09 +00003356- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3357 ValueError consistently across platforms.
3358
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003359- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3360 (64bit Unix, for example), unichr() would truncate its argument and return
3361 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3362
Neal Norwitze7d8be82008-07-31 17:17:14 +00003363- Apply security patches from Apple.
3364
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003365- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3366 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3367
Antoine Pitrou92f82162008-07-25 22:22:08 +00003368- Issue #1819: function calls with several named parameters are now on
3369 average 35% faster (as measured by pybench).
3370
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003371- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3372 the python debugger steps into a class statement: the free variables (local
3373 variables defined in an outer scope) would be deleted from the outer scope.
3374
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003375- Issue #2620: Overflow checking when allocating or reallocating memory
3376 was not always being done properly in some python types and extension
3377 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3378 all been updated to perform better checks and places in the code that
3379 would previously leak memory on the error path when such an allocation
3380 failed have been fixed.

3384
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003385- Issue #3612: Added some missing basic types in ctypes.wintypes.
3386
Benjamin Petersone977ad42008-08-20 01:42:01 +00003387- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3388 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3389
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003390- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3391 version reported by these tools does not necessarily follow the python
3392 version numbering scheme, so the module is less strict when parsing it.
3393
Nick Coghlanf70385a2008-08-18 12:42:46 +00003394- Issue #2235: Added Py3k warnings for types which will become unhashable
3395 under the stricter __hash__ inheritance rules in 3.0. Several types
3396 which did not meet the rules for hash invariants and were already
3397 unhashable in 3.0 have now been explicitly flagged as unhashable in
3398 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3399 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3400
Brett Cannon88f801d2008-08-18 00:46:22 +00003401- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3402 imported into the module but exposed as part of the module's API.
3403
Brett Cannon7b96f072008-08-18 00:41:11 +00003404- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3405
Brett Cannon46225e72008-08-18 00:36:52 +00003406- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3407
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003408- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.

3514
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003515- Issue #643841: The language reference now provides more detailed

3527-----------------
3528
Georg Brandl3e483f62008-07-16 22:57:41 +00003529- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3530 its methods now allow for items objects that can be converted to
3531 an integer using operator.index().
3532
Mark Dickinson64b7e502008-07-16 09:40:03 +00003533- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3534 produced a ValueError instead of giving the correct float.
3535
Eric Smitha5fa5a22008-07-16 00:11:49 +00003536- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3537 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3538
Mark Dickinson7103aa42008-07-15 19:08:33 +00003539- Issue #3008: the float type has a new instance method 'float.hex'
3540 and a new class method 'float.fromhex' to convert floating-point
3541 numbers to and from hexadecimal strings, respectively.
3542
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003543- Issue #2235: __hash__ is once again inherited by default. To allow
3544 collections.Hashable to remain meaningful in the presence of the
3545 default hash implementation (object.__hash__), it is now possible
3546 to explicit block inheritance of hash by setting __hash__=None at
3547 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3548 level.
3549
Nick Coghlanb028f502008-07-13 14:52:36 +00003550- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3551 the parent module cannot be found while performing an absolute import.
3552 This means that an incorrectly defined __package__ attribute will
3553 now only prevent relative imports in that module rather than causing
3554 all imports from that module to fail.
3555
Nick Coghlan14ff9942008-07-08 14:21:42 +00003556- Issue #2517: Allow unicode messages in Exceptions again by correctly

3566 another thread's dictionary.
3567
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003568- Issue #3004: Minor change to slice.indices(): the start and stop
3569 arguments are now treated identically, making the behaviour easier
3570 to describe and understand. For example, slice(None, -10,
3571 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3572 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3573 10, -1).
3574
Georg Brandl278fc502008-07-19 12:46:12 +00003575- Issue #3219: Calling a function with repeated keyword arguments,
3576 f(a=2, a=23), would not cause a syntax error. This was a regression
3577 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003615- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3616 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003617 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003618 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004025- On MacOS X it is now possible to install the framework in 64-bit
4026 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004027 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004028
4029 This is controlled by the configure argument ``--with-universal-archs``:
4030
4031 - ``--with-universal-archs=all``: install 4-way universal
4032
4033 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4034
4035 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4036
4037 This option should be used in combination with ``--enable-universalsdk=``.
4038
4039 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 +00004089- Issue #1631171: Re-implement the 'warnings' module in C (the
4090 original Python code has been kept as backup). This will allow for
4091 using the 'warning's machinery in such places as the parser where
4092 use of pure Python code is not possible. Both the ``showarning()``
4093 and ``formatwarning()`` gain an optional 'line' argument which is
4094 not called by default for backwards-compatibility reasons. Setting
4095 ``warnings.showwarning()`` to an implementation that lacks support
4096 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Issue #2550: The approach used by client/server code for obtaining
4160 ports to listen on in network-oriented tests has been refined in an
4161 effort to facilitate running multiple instances of the entire
4162 regression test suite in parallel without issue.
4163 test_support.bind_port() has been fixed such that it will always
4164 return a unique port -- which wasn't always the case with the
4165 previous implementation, especially if socket options had been set
4166 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4167 new implementation of bind_port() will actually raise an exception
4168 if it is passed an AF_INET/SOCK_STREAM socket with either the
4169 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4170 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4171 the socket it's been passed. This currently only applies to
4172 Windows. This option prevents any other sockets from binding to the
4173 host/port we've bound to, thus removing the possibility of the
4174 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4175 when a second SOCK_STREAM socket binds and accepts to a host/port
4176 that's already been bound by another socket. The optional preferred
4177 port parameter to bind_port() has been removed. Under no
4178 circumstances should tests be hard coding ports!
4179
4180 test_support.find_unused_port() has also been introduced, which will
4181 pass a temporary socket object to bind_port() in order to obtain an
4182 unused port. The temporary socket object is then closed and
4183 deleted, and the port is returned. This method should only be used
4184 for obtaining an unused port in order to pass to an external program
4185 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4186 a parameter to a server-oriented class that doesn't give you direct
4187 access to the underlying socket used.
4188
4189 Finally, test_support.HOST has been introduced, which should be used
4190 for the host argument of any relevant socket calls (i.e. bind and
4191 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004192
4193 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004194 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004195 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4196 test_asynchat and test_socket_ssl.
4197
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198 It is now possible for multiple instances of the regression test
4199 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004254 \Uxxxxxxxx did not accept values outside the Basic Multilingual
4255 Plane. This affected raw unicode literals and the
4256 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
4257 this case, like normal unicode literals and the 'unicode-escape'
4258 codec.

4467
Fred Drakea8ee94b2008-03-01 02:45:07 +00004468- Issue #2051: pyc and pyo files are no longer created with permission

Christian Heimes5224d282008-02-23 15:01:05 +00004474
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004475- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004476 issue 215555 for a discussion.
4477
Eric Smitha73fbe72008-02-23 03:09:44 +00004478- Added the future_builtins module, which contains hex() and oct().
4479 These are the PEP 3127 version of these functions, designed to be
4480 compatible with the hex() and oct() builtins from Python 3.0. They
4481 differ slightly in their output formats from the existing, unchanged
4482 Python 2.6 builtins. The expected usage of the future_builtins
4483 module is:
4484 from future_builtins import hex, oct
4485
Eric Smith7ef40bf2008-02-20 23:34:22 +00004486- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4487 exponents for exponents with absolute value < 100. Follows C99
4488 standard. This is a change on Windows, which would use 3 digits.
4489 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4490 so that any alterations it does to the resulting string will be
4491 available in stringlib/formatter.h (for float.__format__).
4492
Eric Smith5a3c1352008-02-19 13:21:56 +00004493- Implemented PEP 3101, Advanced String Formatting. This adds a new
4494 builtin format(); a format() method for str and unicode; a
4495 __format__() method to object, str, unicode, int, long, float, and
4496 datetime; the class string.Formatter; and the C API
4497 PyObject_Format().
4498
Georg Brandl3ee81df2008-05-17 18:14:43 +00004499- Fixed several potential crashes, all caused by specially crafted
4500 __del__ methods exploiting objects in temporarily inconsistent
4501 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004510- Clear all free lists during a gc.collect() of the highest generation
4511 in order to allow pymalloc to free more arenas. Python may give back
4512 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004513
Georg Brandl3ee81df2008-05-17 18:14:43 +00004514- Issue #2045: Fix an infinite recursion triggered when printing a
4515 subclass of collections.defaultdict, if its default_factory is set
4516 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004517
Christian Heimesf75dbef2008-02-08 00:11:31 +00004518- Fixed a minor memory leak in dictobject.c. The content of the free
4519 list was not freed on interpreter shutdown.
4520
Georg Brandl21e99f42010-03-07 15:23:59 +00004521- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004522 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004523
Georg Brandl3ee81df2008-05-17 18:14:43 +00004524- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4525 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004526 to compact the internal free lists of pre-allocted ints and floats.
4527
Georg Brandl3ee81df2008-05-17 18:14:43 +00004528- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4529 calls. Python expected the return type int but the fork familie
4530 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004531
Georg Brandl3ee81df2008-05-17 18:14:43 +00004532- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4533 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004544- Patch #1473257: generator objects gain a gi_code attribute. This is
4545 the same object as the func_code attribute of the function that
4546 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004547
Georg Brandl3ee81df2008-05-17 18:14:43 +00004548- Issue #1920: "while 0" statements were completely removed by the
4549 compiler, even in the presence of an "else" clause, which is
4550 supposed to be run when the condition is false. Now the compiler
4551 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004552
Guido van Rossumeead05f2008-01-24 18:21:02 +00004553- A few crashers fixed: weakref_in_del.py (issue #1377858);
4554 loosing_dict_ref.py (issue #1303614, test67.py);
4555 borrowed_ref_[34].py (not in tracker).
4556
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004557- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004558 suppressed while an extension is loaded by calling SetErrorMode in
4559 dynload_win.c. The error is still reported properly.
4560
Georg Brandl3ee81df2008-05-17 18:14:43 +00004561- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004562 several extension methods and modules do not work without unicode
4563 support.
4564
Georg Brandl26543b12008-01-21 18:36:51 +00004565- Issue #1882: when compiling code from a string, encoding cookies in the
4566 second line of code were not always recognized correctly.
4567
Georg Brandl14404b62008-01-19 19:27:05 +00004568- Issue #1679: "0x" was taken as a valid integer literal.
4569
Georg Brandl6caad7d2008-01-26 14:19:22 +00004570- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004571 added.
4572
Christian Heimesc94e2b52008-01-14 04:13:37 +00004573- sys.float_info / PyFloat_GetInfo: The floating point information
4574 object was converted from a dict to a specialized structseq object.
4575
Georg Brandl3ee81df2008-05-17 18:14:43 +00004576- Patch #1816: Added sys.flags structseq. It exposes the status of
4577 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004578
Georg Brandl3ee81df2008-05-17 18:14:43 +00004579- Objects/structseq.c: Implemented new structseq representation. The
4580 patch makes structseqs (e.g. the return value of os.stat) more
4581 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004582
Georg Brandl3ee81df2008-05-17 18:14:43 +00004583- Patch #1700288: added a type attribute cache that caches method
4584 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004585
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004586- Bug #1776: __import__() no longer accepts filenames on any platform.
4587 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004588
Georg Brandlaed6c662008-01-07 17:25:53 +00004589- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4590
Georg Brandl3ee81df2008-05-17 18:14:43 +00004591- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4592 envvar and sys.dont_write_bytecode attribute. All these can be set
4593 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004594
Georg Brandl3ee81df2008-05-17 18:14:43 +00004595- Improve some exception messages when Windows fails to load an
4596 extension module. Now we get for example '%1 is not a valid Win32
4597 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004598

Christian Heimes0a8143f2007-12-18 23:22:54 +00004604- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004605 and INF. float("nan"), float("inf") and float("-inf") now work on
4606 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004607
Georg Brandl3ee81df2008-05-17 18:14:43 +00004608- Compiler now generates simpler and faster code for dictionary
4609 literals. The oparg for BUILD_MAP now indicates an estimated
4610 dictionary size. There is a new opcode, STORE_MAP, for adding
4611 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004640- Patch #1739468: Directories and zipfiles containing a __main__.py
4641 file can now be directly executed by passing their name to the
4642 interpreter. The directory/zipfile is automatically inserted as the
4643 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004644
Georg Brandl3ee81df2008-05-17 18:14:43 +00004645- Issue #1265: Fix a problem with sys.settrace, if the tracing
4646 function uses a generator expression when at the same time the
4647 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004648
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004649- sets and frozensets now have an isdisjoint() method.
4650
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004651- optimize the performance of builtin.sum().
4652
Neal Norwitz44f326e2007-10-05 05:29:17 +00004653- Fix warnings found by the new version of the Coverity checker.
4654
Georg Brandl21e99f42010-03-07 15:23:59 +00004655- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004656 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4657 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004658
Georg Brandl3ee81df2008-05-17 18:14:43 +00004659- Issue #1686386: Tuple's tp_repr did not take into account the
4660 possibility of having a self-referential tuple, which is possible
4661 from C code. Nor did object's tp_str consider that a type's tp_str
4662 could do something that could lead to an inifinite recursion.
4663 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4664 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004665
Georg Brandl3ee81df2008-05-17 18:14:43 +00004666- Issue #1164: It was possible to trigger deadlock when using the
4667 'print' statement to write to a file since the GIL was not released
4668 as needed. Now PyObject_Print() does the right thing along with
4669 various tp_print implementations of the built-in types and those in
4670 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004671
Georg Brandl3ee81df2008-05-17 18:14:43 +00004672- Issue #1147: Exceptions were directly allowing string exceptions in
4673 their throw() method even though string exceptions no longer
4674 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004675
Georg Brandl3ee81df2008-05-17 18:14:43 +00004676- Issue #1096: Prevent a segfault from getting the repr of a very
4677 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004678
Brett Cannon1e534b52007-09-07 04:18:30 +00004679- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004680 PyObject_Call() never calling back out to Python code to trigger
4681 recursion depth updates/checks. Required the creation of a static
4682 RuntimeError instance in case normalizing an exception put the
4683 recursion check value past its limit. Fixes crashers
4684 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004685

Neal Norwitz0ac60192007-05-27 04:08:54 +00004699- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004700 __*__ attributes. (Some already existed, e.g., __doc__ and
4701 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004702
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004703- Add -3 option to the interpreter to warn about features that are
4704 deprecated and will be changed/removed in Python 3.0.
4705
Georg Brandl2134e752007-05-21 20:34:16 +00004706- Patch #1686487: you can now pass any mapping after '**' in function
4707 calls.
4708
Collin Winter62903052007-05-18 23:11:24 +00004709- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004710 "except E as target:". This is to provide forwards compatibility
4711 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004715- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004716 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004717
Vinay Sajip8549ce32007-05-06 17:53:37 +00004718- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004719 setting a plain string, ie don't expand to single letter identifiers.
4720
Raymond Hettinger13936692007-04-11 18:40:58 +00004721- Request #1191699: Slices can now be pickled.
4722
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004723- Request #1193128: str.translate() now allows a None argument for
4724 translations that only remove characters without re-mapping the
4725 remaining characters.
4726
Georg Brandl5cb76c12007-03-21 09:00:39 +00004727- Patch #1682205: a TypeError while unpacking an iterable is no longer
4728 masked by a generic one with the message "unpack non-sequence".
4729

4731
Guido van Rossum143b5642007-03-23 04:58:42 +00004732- Bug #1683368: The object.__init__() and object.__new__() methods are
4733 now stricter in rejecting excess arguments. The only time when
4734 either allows excess arguments is when it is not overridden and the
4735 other one is. For backwards compatibility, when both are
4736 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004737 warning later). Also, type.__init__() insists on the same signature

Georg Brandl3ee81df2008-05-17 18:14:43 +00004740- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4741 object to complex using its __complex__() method before falling back
4742 to the __float__() method. Therefore, the functions in the cmath
4743 module now can operate on objects that define a __complex__()
4744 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004766 its argument, if it exists. If not, it will work like before. This
4767 allows customizing the output of dir() in the presence of a
4768 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00004780- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00004850- Bug #1545497: when given an explicit base, int() did ignore NULs
4851 embedded in the string to convert.
4852
Georg Brandl846f73a2006-10-08 07:11:54 +00004853- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004901 generator expressions (x for x, in ... ) works again. Fixing this
4902 problem required changing the .pyc magic number. This means that
4903 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005710- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5711 with RFC 3207 and forgets any knowledge obtained from the server not
5712 obtained from the TLS negotiation itself. Patch contributed by Bill
5713 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005715- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005716 that the SMTP.starttls() caller no longer needs to call ehlo()
5717 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005718 does not claim to support starttls. Adds the
5719 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5800 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5801 silently miscode subclasses of those types. Now, it raises a
5802 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005803

Georg Brandl3ee81df2008-05-17 18:14:43 +00005818 time so that opening a database previously created with the DB_DUP
5819 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5820 opens. Specifically: dictionary assignment to a DB object will
5821 replace all values for a given key when the database allows
5822 duplicate values. DB users should use DB.put(k, v) when they want
5823 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005824

5830 characters with ASCII value less than 32. Also, it correctly quotes
5831 dots only if they occur on a single line, as opposed to the previous
5832 behavior of quoting dots if they are the second character of any
5833 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005834
