768 start byte and the continuation byte(s) are now considered invalid, instead
769 of the number of bytes specified by the start byte.
770 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
771 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
772 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

782 objects. (1) The comparison could incorrectly return True in some cases
783 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000925- Issue #1533: Fix inconsistency in range function argument processing: any
926 non-float non-integer argument is now converted to an integer (if possible)
927 using its __int__ method. Previously, only small arguments were treated this
928 way; larger arguments (those whose __int__ was outside the range of a C long)
929 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +0000937 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable

965 inheritance with the underlying socket object. The cheap inheritance has been
966 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +0000979- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
980 operation raises multiple signals and more than one of those signals is
981 trapped, the specification determines the order in which the signals should be
982 handled. In many cases this order wasn't being followed, leading to the wrong

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00001149
1150Core and Builtins
1151-----------------
1152
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001153- Issue #7301: Add environment variable $PYTHONWARNINGS.
1154
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001155- Issue #8329: Don't return the same lists from select.select when no fds are
1156 changed.
1157
Georg Brandlfee0f442010-05-22 21:26:21 +00001158- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001159 on 64-bit machines. The shift count for either left or right shift is
1160 permitted to be up to sys.maxsize.
1161
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001162- Ensure that tokenization of identifiers is not affected by locale.
1163
Georg Brandlfee0f442010-05-22 21:26:21 +00001164- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001165
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001166- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1167
Georg Brandlfee0f442010-05-22 21:26:21 +00001168- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1169 with a non-empty format string. This is an effort to future-proof user
1170 code. If a derived class does not currently implement __format__ but later
1171 adds its own __format__, it would most likely break user code that had
1172 supplied a format string. This will be changed to a DeprecationWaring in
1173 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001174
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001175- Issue #8268: Old-style classes (not just instances) now support weak

1177
Georg Brandlfee0f442010-05-22 21:26:21 +00001178- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
1179 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00001180
Victor Stinnerc7790ed2010-03-22 12:36:28 +00001181- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00001182
Benjamin Peterson96545892010-03-21 20:21:00 +00001183- Issue #6474: Make error message from passing an inadequate number of keyword
1184 arguments to a function correct.
1185
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001186- Issue #8164: Don't allow lambda functions to have a docstring.
1187
Victor Stinner66644262010-03-10 22:30:19 +00001188- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001189 (SIGINT). If an error occurs while importing the site module, the error is
1190 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001191 module.
1192
Collin Winter001a3952010-03-18 21:54:01 +00001193- Code objects now support weak references.

1199
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001200- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001201 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1202 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001203
Benjamin Peterson76a23c12010-04-04 23:23:22 +00001204- Issue #8310: Allow dis to examine new style classes.
1205
Georg Brandlfee0f442010-05-22 21:26:21 +00001206- Issue #8257: The Decimal construct now accepts a float instance directly,
1207 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001208
1209 >>> Decimal(1.1)
1210 Decimal('1.100000000000000088817841970012523233890533447265625')
1211
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001212- collections.Counter() now supports a subtract() method.
1213
Georg Brandlfee0f442010-05-22 21:26:21 +00001214- The functools module now has a total_ordering() class decorator to simplify
1215 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001216
Georg Brandlfee0f442010-05-22 21:26:21 +00001217- The functools module also adds cmp_to_key() as a tool to transition old-style
1218 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001219
Georg Brandlfee0f442010-05-22 21:26:21 +00001220- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1221 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001222
Georg Brandlfee0f442010-05-22 21:26:21 +00001223- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1224 InvalidOperation instead of returning False. (Comparisons involving a quiet
1225 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1226 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001227
Georg Brandlfee0f442010-05-22 21:26:21 +00001228- Issue #2531: Comparison operations between floats and Decimal instances now
1229 return a result based on the numeric values of the operands; previously they
1230 returned an arbitrary result based on the relative ordering of id(float) and
1231 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001232
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001233- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001234 argument `-` which tells it to read files to compile from stdin. Each line is
1235 read on demand and the named file is compiled immediately. (Original patch by
1236 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001237
Georg Brandlfee0f442010-05-22 21:26:21 +00001238- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1239 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001241- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1242 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001243 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001244
Georg Brandlfee0f442010-05-22 21:26:21 +00001245- Comparisons using one of <, <=, >, >= between a complex instance and a
1246 Fractions instance now raise TypeError instead of returning True/False. This
1247 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1248 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001249
Michael Foorde6410c52010-03-29 20:04:23 +00001250- Addition of ``WeakSet`` to the ``weakref`` module.

1258
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001259- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001260 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1261 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001262
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001263- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1264 deprecated.
1265
Georg Brandlfee0f442010-05-22 21:26:21 +00001266- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1267 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001268

1273 existing at the same time, causing a Unicode error when configuration code
1274 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001275
Georg Brandlfee0f442010-05-22 21:26:21 +00001276- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
1277 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00001278
Antoine Pitroueee91cd2010-03-26 19:27:16 +00001279- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
1280 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1281 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00001282
Florent Xiclunacf82fa62010-03-21 12:27:20 +00001283- Issue #8179: Fix macpath.realpath() on a non-existing path.

1297 locale.
Matthias Klose358e7ff2010-03-15 13:42:23 +00001298
Georg Brandlfee0f442010-05-22 21:26:21 +00001299- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set
1300 to an non existent program name and Python is unable to retrieve the real

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001303- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001304 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1305 log file to compute the next rollover time. If the log file does not exist,
1306 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001307
Georg Brandlba83f822010-03-14 09:50:54 +00001308- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

1315
Georg Brandlba83f822010-03-14 09:50:54 +00001316- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1317 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1318 This is a behavior change, so email's minor version number is now bumped, to
1319 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00001320

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001347- Issue #8300: When passing a non-integer argument to struct.pack with any
1348 integer format code, struct.pack first attempts to convert the non-integer
1349 using its __index__ method. If that method is non-existent or raises
1350 TypeError it goes on to try the __int__ method, as described below.
1351
Georg Brandlba83f822010-03-14 09:50:54 +00001352- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1353 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1354 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001355 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1356 inconsistent: __int__ was used for some integer codes but not for others, and
1357 the set of integer codes for which it was used differed between native packing
1358 and standard packing.)

1612 returning NULL. The macro now returns a statically allocated empty string
1613 instead.

1762Core and Builtins
1763-----------------
1764
Georg Brandlba83f822010-03-14 09:50:54 +00001765- The ``__complex__()`` method is now looked up on the class of instances to
1766 make it consistent with other special methods.

1770
Mark Dickinson1b34d252010-01-01 17:27:30 +00001771- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001772 DeprecationWarning when passed a float argument where an integer was expected.
1773 These functions and methods now raise TypeError instead. The majority of the
1774 effects of this change are in the extension modules, but some core functions
1775 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1776 and many unicode/str methods.

1790 of integers: the result of a/b is now correctly rounded for ints a and b (at
1791 least on IEEE 754 platforms), and in particular does not depend on the
1792 internal representation of a long.

1800
Georg Brandlba83f822010-03-14 09:50:54 +00001801 These executables now work properly with the arch(1) command: ``arch -ppc
1802 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001959- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1960 decimal string that's guaranteed to round back to x under correct rounding
1961 (with round-half-to-even rounding mode). Previously it gave a string based on
1962 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1963 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1964 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001965
Georg Brandlba83f822010-03-14 09:50:54 +00001966- Issue #7117: On almost all platforms: float-to-string and string-to-float
1967 conversions within Python are now correctly rounded. Places these conversions
1968 occur include: str for floats and complex numbers; the float and complex
1969 constructors; old-style and new-style numeric formatting; serialization and
1970 deserialization of floats and complex numbers using marshal, pickle and json;
1971 parsing of float and imaginary literals in Python code; Decimal-to-float
1972 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001973
Georg Brandlba83f822010-03-14 09:50:54 +00001974 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1975 providing correctly-rounded strtod and dtoa C functions. This code is
1976 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1977 the C compiler. There may be a small number of platforms on which correct
1978 operation of this code cannot be guaranteed, so the code is not used: notably,
1979 this applies to platforms where the C double format is not IEEE 754 binary64,
1980 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1981 and Python's configure script is unable to determine how to change the FPU
1982 precision. On these platforms conversions use the platform strtod and dtoa,
1983 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001985- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1986 uses the correctly-rounded string <-> float conversions described above (when
1987 available), and so produces correctly rounded results that will display nicely
1988 under the float repr. There are two related small changes: (1) round now
1989 accepts any class with an ``__index__()`` method for its second argument (but
1990 no longer accepts floats for the second argument), and (2) an excessively
1991 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1992 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002135 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2136 (2) parsing of strings representing infinities and nans was locale aware; and
2137 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002139- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2140 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2141 but with at least one decimal point and with a default precision
2142 of 12. Previously, the behavior the same but with a default precision of 6.
2143 This more closely matches ``str()``, and reduces surprises when adding
2144 alignment flags to the empty presentation type. This also affects the new
2145 complex.__format__ in the same way.
2146
2147- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2148 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00002210 untrackable objects are not tracked by the garbage collector. This can reduce

2219 internal representation of integers, for performance reasons. Base 2**30 is
2220 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00002328- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2329 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2330 instances. On a typical machine this saves 3 bytes of memory (on average) per
2331 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002333- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2335 instead of throwing a MemoryError.
2336
Georg Brandlba83f822010-03-14 09:50:54 +00002337- Issue #3689: The list reversed iterator now supports __length_hint__ instead

2342
Georg Brandlba83f822010-03-14 09:50:54 +00002343- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2344 file objects with closefd=False. The file descriptor is still kept open but
2345 the file object behaves like a closed file. The ``FileIO`` object also got a
2346 new readonly attribute ``closefd``.

2365
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002366- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002367 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002369- On windows, ``os.chdir()`` given unicode was not working if
2370 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2371 this code path is really executed because I cannot move to such directory on
2372 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002374- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2375 element is temporarily replaced with an equivalent frozenset. But the
2376 eventual KeyError would always report the empty ``frozenset()`` as the missing
2377 key. Now it correctly refers to the initial element.

2395 returned them on 64bit platforms.
2396
Walter Dörwalded960ac2009-05-03 22:36:33 +00002397- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2398 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2399 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2400 of using the replace error handler in PyUnicode_DecodeUTF8().
2401
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002402- Issue #3739: The unicode-internal encoder now reports the number of characters
2403 consumed like any other encoder (instead of the number of bytes).
2404
Georg Brandlba83f822010-03-14 09:50:54 +00002405- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2406 allocator will be automatically disabled when running under Valgrind. This
2407 gives improved memory leak detection when running under Valgrind, while taking
2408 advantage of pymalloc at other times.

3575 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3576 neither __int__ nor __long__, TypeError used to be raised (with a

3774
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003775- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3776 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3777 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3778 ``printf`` function, whereas PyString_FromFormat has an independent
3779 implementation and uses "%zd" on all platforms for size_t values.
3780 This makes a difference on win64, where ``printf`` needs "%Id" to display
3781 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003783- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3787 object; previously an int would be returned for small values. the __long__
3788 method is allowed to return either an int or a long, but the behaviour of
3789 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003791- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00003797 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003798 was correctly parsed but parsing of subsequent arguments failed.
3799
Vinay Sajip35e3b032008-09-01 14:33:59 +00003800- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003801 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3802 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3803 when given a tuple of classes as second argument, were looking up
3804 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3805 type object.
3806
Neal Norwitz18aa3882008-08-24 05:04:52 +00003807- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003876 warnings.catch_warnings() along with some API cleanup. Expanding the tests

3950-----------------
3951
Guido van Rossumf8402962008-08-20 15:01:50 +00003952- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3953 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3954 extensions do not automatically benefit from the class attribute
3955 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3956 to their tp_flags field if they care. This is a backwards
3957 compatibility feature; in 3.0, all types will use the cache by
3958 default.
3959
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003960- Keyword arguments can now follow starred arguments. (``f(a, *args,
3961 keyword=23)`` is now valid syntax.)
3962
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003963- ctypes function pointers that are COM methods have a boolean True
3964 value again.

Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003976- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3977 (64bit Unix, for example), unichr() would truncate its argument and return
3978 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

3983 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3984
Antoine Pitrou92f82162008-07-25 22:22:08 +00003985- Issue #1819: function calls with several named parameters are now on
3986 average 35% faster (as measured by pybench).
3987
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003988- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3989 the python debugger steps into a class statement: the free variables (local
3990 variables defined in an outer scope) would be deleted from the outer scope.
3991
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003992- Issue #2620: Overflow checking when allocating or reallocating memory
3993 was not always being done properly in some python types and extension
3994 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3995 all been updated to perform better checks and places in the code that
3996 would previously leak memory on the error path when such an allocation
3997 failed have been fixed.

4003
Benjamin Petersone977ad42008-08-20 01:42:01 +00004004- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4005 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4006
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004007- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4008 version reported by these tools does not necessarily follow the python
4009 version numbering scheme, so the module is less strict when parsing it.
4010
Nick Coghlanf70385a2008-08-18 12:42:46 +00004011- Issue #2235: Added Py3k warnings for types which will become unhashable
4012 under the stricter __hash__ inheritance rules in 3.0. Several types
4013 which did not meet the rules for hash invariants and were already
4014 unhashable in 3.0 have now been explicitly flagged as unhashable in
4015 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4016 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4017
Brett Cannon88f801d2008-08-18 00:46:22 +00004018- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4019 imported into the module but exposed as part of the module's API.
4020

4040 after a 302 response in the case of not going through a proxy.
4041
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004042- Issue #2676: in the email package, content-type parsing was hanging on
4043 pathological input because of quadratic or exponential behaviour of a
4044 regular expression.
4045
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004046- Issue #3476: binary buffered reading through the new "io" library is now
4047 thread-safe.
4048
Brett Cannonbf3157b2008-08-14 05:00:03 +00004049- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4050 since mimetools itself is deprecated. Because modules are cached, all
4051 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4052
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004053- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00004055- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4056 menu entries were not deleted.
4057
Brett Cannon83e81842008-08-09 23:30:55 +00004058- Copied the implementation of reduce() to _functools.reduce() to have a

4060
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004061- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4062 a MemoryError rather than silently stop the iteration.
4063
Guido van Rossum59ce9012008-08-09 14:55:34 +00004064- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4065 to _sre.compile() will now be rejected. This should not affect anybody
4066 since the re.compile() function never generates invalid re-bytecode.
4067
Skip Montanaroa032bf42008-08-08 22:52:51 +00004068- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4069 upon first access it can be automatically initialized from the csv file if
4070 it wasn't initialized during instantiation.
4071
Brett Cannon3aa2a492008-08-06 22:28:09 +00004072- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4073 the reload() built-in has been removed.
4074
Brett Cannon7e30b672008-08-04 21:52:25 +00004075- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004076 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4084 raised an AttributeError.
4085
Benjamin Peterson01a24322008-07-28 23:35:27 +00004086- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004087 asking for a specific length. This problem only affected files opened
4088 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004089

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004113- Issue #3394: zipfile.writestr sets external attributes when passed a
4114 file name rather than a ZipInfo instance, so files are extracted with
4115 mode 0600 rather than 000 under Unix.
4116
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004117- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4118 argument in python 2.5, this broke code that subclassed Popen to include its
4119 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004129- Issue #2235: the C API function PyObject_HashNotImplemented and its
4130 interaction with the tp_hash slot (added in 2.6b2) are now documented
4131
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004132- Issue #643841: The language reference now provides more detailed
4133 coverage of the lookup process for special methods. The disclaimers
4134 regarding lack of coverage of new-style classes have also been
4135 removed, since the coverage is now fairly reasonable.

4139================================
4140
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004141*Release date: 17-Jul-2008*
4142
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004143Core and Builtins
4144-----------------
4145
Georg Brandl3e483f62008-07-16 22:57:41 +00004146- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4147 its methods now allow for items objects that can be converted to
4148 an integer using operator.index().
4149
Mark Dickinson64b7e502008-07-16 09:40:03 +00004150- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4151 produced a ValueError instead of giving the correct float.
4152
Eric Smitha5fa5a22008-07-16 00:11:49 +00004153- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4154 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4155
Mark Dickinson7103aa42008-07-15 19:08:33 +00004156- Issue #3008: the float type has a new instance method 'float.hex'
4157 and a new class method 'float.fromhex' to convert floating-point
4158 numbers to and from hexadecimal strings, respectively.
4159
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004160- Issue #2235: __hash__ is once again inherited by default. To allow
4161 collections.Hashable to remain meaningful in the presence of the
4162 default hash implementation (object.__hash__), it is now possible
4163 to explicit block inheritance of hash by setting __hash__=None at
4164 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4165 level.
4166
Nick Coghlanb028f502008-07-13 14:52:36 +00004167- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4168 the parent module cannot be found while performing an absolute import.
4169 This means that an incorrectly defined __package__ attribute will
4170 now only prevent relative imports in that module rather than causing
4171 all imports from that module to fail.
4172
Nick Coghlan14ff9942008-07-08 14:21:42 +00004173- Issue #2517: Allow unicode messages in Exceptions again by correctly
4174 bypassing the instance dictionary when looking up __unicode__ on
4175 new-style classes.
4176
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004177- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4178 set to a custom object whose write() method happens to install
4179 another file in sys.stdout.
4180
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004181- Issue #3088: Corrected a race condition in classes derived from
4182 threading.local: the first member set by a thread could be saved in
4183 another thread's dictionary.
4184
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004185- Issue #3004: Minor change to slice.indices(): the start and stop
4186 arguments are now treated identically, making the behaviour easier
4187 to describe and understand. For example, slice(None, -10,
4188 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4189 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4190 10, -1).
4191
Georg Brandl278fc502008-07-19 12:46:12 +00004192- Issue #3219: Calling a function with repeated keyword arguments,
4193 f(a=2, a=23), would not cause a syntax error. This was a regression
4194 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004195
Georg Brandl278fc502008-07-19 12:46:12 +00004196- Issue #2862: Make int and float freelist management consistent with
4197 other freelists. Changes their CompactFreeList apis into
4198 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00004203- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4204 api functions without holding the GIL, which could lead to a fatal
4205 error when they failed.
4206
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004207- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004215- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4216 ForkingPickler.register() to resolve conflict with ctypes.
4217
Vinay Sajip51e65192008-07-18 09:01:10 +00004218- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004219
Thomas Heller880f5292008-07-15 19:39:38 +00004220- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4221 a valid dlerror() message.
4222
Thomas Heller2bad6572008-07-15 17:19:50 +00004223- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4224 incomplete structure was created.
4225
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004226- Issue #3339: dummy_thread.acquire() should not return None.

4229
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004230- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004231
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004232- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4233 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004234 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004235 content-length. The problem had been corrected in the 2.4 branch, but never
4236 merged into trunk.
4237
Georg Brandle78fbcc2008-07-05 10:13:36 +00004238- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004249 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004250
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004251- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4252 handling is now the same as that of other special attributes like __name__).
4253
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004254- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4255 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004644 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004645
4646 This is controlled by the configure argument ``--with-universal-archs``:
4647
4648 - ``--with-universal-archs=all``: install 4-way universal
4649
4650 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4651
4652 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4653
4654 This option should be used in combination with ``--enable-universalsdk=``.
4655
4656 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 +00004706- Issue #1631171: Re-implement the 'warnings' module in C (the
4707 original Python code has been kept as backup). This will allow for
4708 using the 'warning's machinery in such places as the parser where
4709 use of pure Python code is not possible. Both the ``showarning()``
4710 and ``formatwarning()`` gain an optional 'line' argument which is
4711 not called by default for backwards-compatibility reasons. Setting
4712 ``warnings.showwarning()`` to an implementation that lacks support
4713 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004776- Issue #2550: The approach used by client/server code for obtaining
4777 ports to listen on in network-oriented tests has been refined in an
4778 effort to facilitate running multiple instances of the entire
4779 regression test suite in parallel without issue.
4780 test_support.bind_port() has been fixed such that it will always
4781 return a unique port -- which wasn't always the case with the
4782 previous implementation, especially if socket options had been set
4783 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4784 new implementation of bind_port() will actually raise an exception
4785 if it is passed an AF_INET/SOCK_STREAM socket with either the
4786 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4787 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4788 the socket it's been passed. This currently only applies to
4789 Windows. This option prevents any other sockets from binding to the
4790 host/port we've bound to, thus removing the possibility of the
4791 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4792 when a second SOCK_STREAM socket binds and accepts to a host/port
4793 that's already been bound by another socket. The optional preferred
4794 port parameter to bind_port() has been removed. Under no
4795 circumstances should tests be hard coding ports!
4796
4797 test_support.find_unused_port() has also been introduced, which will
4798 pass a temporary socket object to bind_port() in order to obtain an
4799 unused port. The temporary socket object is then closed and
4800 deleted, and the port is returned. This method should only be used
4801 for obtaining an unused port in order to pass to an external program
4802 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4803 a parameter to a server-oriented class that doesn't give you direct
4804 access to the underlying socket used.
4805
4806 Finally, test_support.HOST has been introduced, which should be used
4807 for the host argument of any relevant socket calls (i.e. bind and
4808 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004809
4810 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004811 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

5082Core and builtins
5083-----------------
5084
Fred Drakea8ee94b2008-03-01 02:45:07 +00005085- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005086 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005087
Georg Brandlad61bc82008-02-23 15:11:18 +00005088- Issue #2067: file.__exit__() now calls subclasses' close() method.
5089
5090- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005091
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005092- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005093 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005094
Eric Smitha73fbe72008-02-23 03:09:44 +00005095- Added the future_builtins module, which contains hex() and oct().
5096 These are the PEP 3127 version of these functions, designed to be
5097 compatible with the hex() and oct() builtins from Python 3.0. They
5098 differ slightly in their output formats from the existing, unchanged
5099 Python 2.6 builtins. The expected usage of the future_builtins
5100 module is:
5101 from future_builtins import hex, oct
5102
Eric Smith7ef40bf2008-02-20 23:34:22 +00005103- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5104 exponents for exponents with absolute value < 100. Follows C99
5105 standard. This is a change on Windows, which would use 3 digits.
5106 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5107 so that any alterations it does to the resulting string will be
5108 available in stringlib/formatter.h (for float.__format__).
5109
Eric Smith5a3c1352008-02-19 13:21:56 +00005110- Implemented PEP 3101, Advanced String Formatting. This adds a new
5111 builtin format(); a format() method for str and unicode; a
5112 __format__() method to object, str, unicode, int, long, float, and
5113 datetime; the class string.Formatter; and the C API
5114 PyObject_Format().
5115
Georg Brandl3ee81df2008-05-17 18:14:43 +00005116- Fixed several potential crashes, all caused by specially crafted
5117 __del__ methods exploiting objects in temporarily inconsistent
5118 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005119
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005120- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005121 prevent a possible crash: an Abstract Base Class would try to access
5122 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005123
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124- Fixed repr() and str() of complex numbers with infinity or nan as
5125 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005126
Georg Brandl3ee81df2008-05-17 18:14:43 +00005127- Clear all free lists during a gc.collect() of the highest generation
5128 in order to allow pymalloc to free more arenas. Python may give back
5129 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005130
Georg Brandl3ee81df2008-05-17 18:14:43 +00005131- Issue #2045: Fix an infinite recursion triggered when printing a
5132 subclass of collections.defaultdict, if its default_factory is set
5133 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005134
Christian Heimesf75dbef2008-02-08 00:11:31 +00005135- Fixed a minor memory leak in dictobject.c. The content of the free
5136 list was not freed on interpreter shutdown.
5137
Georg Brandl21e99f42010-03-07 15:23:59 +00005138- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005139 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5142 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005143 to compact the internal free lists of pre-allocted ints and floats.
5144
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5146 calls. Python expected the return type int but the fork familie
5147 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005148
Georg Brandl3ee81df2008-05-17 18:14:43 +00005149- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5150 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005151
Georg Brandl3ee81df2008-05-17 18:14:43 +00005152- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5153 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005154
Georg Brandl3ee81df2008-05-17 18:14:43 +00005155- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5156 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005157
Georg Brandl3ee81df2008-05-17 18:14:43 +00005158- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5159 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005160
Georg Brandl3ee81df2008-05-17 18:14:43 +00005161- Patch #1473257: generator objects gain a gi_code attribute. This is
5162 the same object as the func_code attribute of the function that
5163 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005164
Georg Brandl3ee81df2008-05-17 18:14:43 +00005165- Issue #1920: "while 0" statements were completely removed by the
5166 compiler, even in the presence of an "else" clause, which is
5167 supposed to be run when the condition is false. Now the compiler
5168 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005169
Guido van Rossumeead05f2008-01-24 18:21:02 +00005170- A few crashers fixed: weakref_in_del.py (issue #1377858);
5171 loosing_dict_ref.py (issue #1303614, test67.py);
5172 borrowed_ref_[34].py (not in tracker).
5173
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005174- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005175 suppressed while an extension is loaded by calling SetErrorMode in
5176 dynload_win.c. The error is still reported properly.
5177
Georg Brandl3ee81df2008-05-17 18:14:43 +00005178- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005179 several extension methods and modules do not work without unicode
5180 support.
5181
Georg Brandl26543b12008-01-21 18:36:51 +00005182- Issue #1882: when compiling code from a string, encoding cookies in the
5183 second line of code were not always recognized correctly.
5184
Georg Brandl14404b62008-01-19 19:27:05 +00005185- Issue #1679: "0x" was taken as a valid integer literal.
5186
Georg Brandl6caad7d2008-01-26 14:19:22 +00005187- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005188 added.
5189
Christian Heimesc94e2b52008-01-14 04:13:37 +00005190- sys.float_info / PyFloat_GetInfo: The floating point information
5191 object was converted from a dict to a specialized structseq object.
5192
Georg Brandl3ee81df2008-05-17 18:14:43 +00005193- Patch #1816: Added sys.flags structseq. It exposes the status of
5194 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005195
Georg Brandl3ee81df2008-05-17 18:14:43 +00005196- Objects/structseq.c: Implemented new structseq representation. The
5197 patch makes structseqs (e.g. the return value of os.stat) more
5198 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005199
Georg Brandl3ee81df2008-05-17 18:14:43 +00005200- Patch #1700288: added a type attribute cache that caches method
5201 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005202
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005203- Bug #1776: __import__() no longer accepts filenames on any platform.
5204 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005205
Georg Brandlaed6c662008-01-07 17:25:53 +00005206- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5207
Georg Brandl3ee81df2008-05-17 18:14:43 +00005208- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5209 envvar and sys.dont_write_bytecode attribute. All these can be set
5210 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005211
Georg Brandl3ee81df2008-05-17 18:14:43 +00005212- Improve some exception messages when Windows fails to load an
5213 extension module. Now we get for example '%1 is not a valid Win32
5214 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005215
Georg Brandl3ee81df2008-05-17 18:14:43 +00005216- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005218- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5219 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005220
Christian Heimes0a8143f2007-12-18 23:22:54 +00005221- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005222 and INF. float("nan"), float("inf") and float("-inf") now work on
5223 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005224
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225- Compiler now generates simpler and faster code for dictionary
5226 literals. The oparg for BUILD_MAP now indicates an estimated
5227 dictionary size. There is a new opcode, STORE_MAP, for adding
5228 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005229
Georg Brandl3ee81df2008-05-17 18:14:43 +00005230- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00005231
Georg Brandl3ee81df2008-05-17 18:14:43 +00005232- Issue #1620: New property decorator syntax was modifying the
5233 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00005234
Georg Brandl3ee81df2008-05-17 18:14:43 +00005235- Issue #1538: Avoid copying string in split/rsplit if the split char
5236 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005237
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005238- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005239 SystemError.
5240
Nick Coghlanef01d822007-12-03 12:55:17 +00005241- PEP 366: Allow explicit relative imports when executing modules
5242 inside packages with the -m switch via a new module level
5243 __package__ attribute.
5244
Georg Brandl3ee81df2008-05-17 18:14:43 +00005245- Issue #1402: Fix a crash on exit, when another thread is still
5246 running, and if the deallocation of its frames somehow calls the
5247 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005248

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005252 attribute of an empty cell object.
5253
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254- Issue #1460: The utf-7 incremental decoder did not accept truncated
5255 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005257- Patch #1739468: Directories and zipfiles containing a __main__.py
5258 file can now be directly executed by passing their name to the
5259 interpreter. The directory/zipfile is automatically inserted as the
5260 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005261
Georg Brandl3ee81df2008-05-17 18:14:43 +00005262- Issue #1265: Fix a problem with sys.settrace, if the tracing
5263 function uses a generator expression when at the same time the
5264 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005265
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005266- sets and frozensets now have an isdisjoint() method.
5267
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005268- optimize the performance of builtin.sum().
5269
Neal Norwitz44f326e2007-10-05 05:29:17 +00005270- Fix warnings found by the new version of the Coverity checker.
5271
Georg Brandl21e99f42010-03-07 15:23:59 +00005272- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005273 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5274 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005275
Georg Brandl3ee81df2008-05-17 18:14:43 +00005276- Issue #1686386: Tuple's tp_repr did not take into account the
5277 possibility of having a self-referential tuple, which is possible
5278 from C code. Nor did object's tp_str consider that a type's tp_str
5279 could do something that could lead to an inifinite recursion.
5280 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5281 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005282
Georg Brandl3ee81df2008-05-17 18:14:43 +00005283- Issue #1164: It was possible to trigger deadlock when using the
5284 'print' statement to write to a file since the GIL was not released
5285 as needed. Now PyObject_Print() does the right thing along with
5286 various tp_print implementations of the built-in types and those in
5287 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005288
Georg Brandl3ee81df2008-05-17 18:14:43 +00005289- Issue #1147: Exceptions were directly allowing string exceptions in
5290 their throw() method even though string exceptions no longer
5291 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005292
Georg Brandl3ee81df2008-05-17 18:14:43 +00005293- Issue #1096: Prevent a segfault from getting the repr of a very
5294 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005295
Brett Cannon1e534b52007-09-07 04:18:30 +00005296- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005297 PyObject_Call() never calling back out to Python code to trigger
5298 recursion depth updates/checks. Required the creation of a static
5299 RuntimeError instance in case normalizing an exception put the
5300 recursion check value past its limit. Fixes crashers
5301 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005302
Georg Brandl3ee81df2008-05-17 18:14:43 +00005303- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005316- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005317 __*__ attributes. (Some already existed, e.g., __doc__ and
5318 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005319
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005320- Add -3 option to the interpreter to warn about features that are
5321 deprecated and will be changed/removed in Python 3.0.
5322

5324 calls.
5325
Collin Winter62903052007-05-18 23:11:24 +00005326- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005327 "except E as target:". This is to provide forwards compatibility
5328 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005329
Brett Cannon229cee22007-05-05 01:34:02 +00005330- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005332- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005333 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005335- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005336 setting a plain string, ie don't expand to single letter identifiers.
5337
Raymond Hettinger13936692007-04-11 18:40:58 +00005338- Request #1191699: Slices can now be pickled.

5348
Guido van Rossum143b5642007-03-23 04:58:42 +00005349- Bug #1683368: The object.__init__() and object.__new__() methods are
5350 now stricter in rejecting excess arguments. The only time when
5351 either allows excess arguments is when it is not overridden and the
5352 other one is. For backwards compatibility, when both are
5353 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005354 warning later). Also, type.__init__() insists on the same signature
5355 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005356
Georg Brandl3ee81df2008-05-17 18:14:43 +00005357- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5358 object to complex using its __complex__() method before falling back
5359 to the __float__() method. Therefore, the functions in the cmath
5360 module now can operate on objects that define a __complex__()
5361 method.

5378
Georg Brandl7b9c5552007-03-12 14:30:05 +00005379- Bug #1678647: write a newline after printing an exception in any
5380 case, even when converting the value to a string failed.
5381
Georg Brandl871f1bc2007-03-12 13:17:36 +00005382- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005383 its argument, if it exists. If not, it will work like before. This
5384 allows customizing the output of dir() in the presence of a
5385 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005386
Collin Winter276887b2007-03-12 16:11:39 +00005387- Patch #922167: Python no longer segfaults when faced with infinitely
5388 self-recursive reload() calls (as reported by bug #742342).

5394 parthensized forms. This means complex(repr(x)) now works instead of
5395 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005396
Georg Brandlaa2321b2007-03-07 00:40:28 +00005397- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005398 makes the filenames the warning module prints much more sensible
5399 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005400

Georg Brandl0fca97a2007-03-05 22:28:08 +00005412- Patch #1674228: when assigning a slice (old-style), check for the
5413 sq_ass_slice instead of the sq_slice slot.
5414
Georg Brandl3ee81df2008-05-17 18:14:43 +00005415- When printing an unraisable error, don't print exceptions. before
5416 the name. This duplicates the behavior whening normally printing
5417 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005950 AttributeError instead of an IOError when the server's response
5951 didn't contain a valid HTTP status line.

6042 TestCase and TestSuite subclasses (not instances) are no longer
6043 accepted in TestSuite.addTest(). This should cause no

6045 -- the failure just occurred later, with a more cumbersome

Georg Brandl3ee81df2008-05-17 18:14:43 +00006327- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6328 with RFC 3207 and forgets any knowledge obtained from the server not
6329 obtained from the TLS negotiation itself. Patch contributed by Bill
6330 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006331
Georg Brandl3ee81df2008-05-17 18:14:43 +00006332- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006333 that the SMTP.starttls() caller no longer needs to call ehlo()
6334 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006335 does not claim to support starttls. Adds the
6336 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6417 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6418 silently miscode subclasses of those types. Now, it raises a
6419 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006420

Georg Brandl3ee81df2008-05-17 18:14:43 +00006435 time so that opening a database previously created with the DB_DUP
6436 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6437 opens. Specifically: dictionary assignment to a DB object will
6438 replace all values for a given key when the database allows
6439 duplicate values. DB users should use DB.put(k, v) when they want
6440 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006441

6447 characters with ASCII value less than 32. Also, it correctly quotes
6448 dots only if they occur on a single line, as opposed to the previous
6449 behavior of quoting dots if they are the second character of any
6450 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006451

Georg Brandl3ee81df2008-05-17 18:14:43 +00006780- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6781 to ``PyTuple_SetItem``, it can be used to populate a brand new
6782 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006783
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006784- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006786- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6787 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6788 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006789
6790- Patch #1720595: add T_BOOL to the range of structmember types.
6791
6792- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6793 ``PyFloat_GetInfo()`` to the float API.
6794
Georg Brandl3ee81df2008-05-17 18:14:43 +00006795- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6796 of w# format code incorrectly truncated the length to an int, even
6797 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6798 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006799
Georg Brandl3ee81df2008-05-17 18:14:43 +00006800- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6801 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006802
Georg Brandl3ee81df2008-05-17 18:14:43 +00006803- PEP 3123: Provide forward compatibility with Python 3.0, while
6804 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6805 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006806
Georg Brandl3ee81df2008-05-17 18:14:43 +00006807- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6808 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006809
6810- Patch #1733960: Allow T_LONGLONG to accept ints.
6811
6812- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6813
Christian Heimes000a0742008-01-03 22:16:32 +00006814- Added a new API function ``PyImport_ImportModuleNoBlock``.
6815
Georg Brandl6caad7d2008-01-26 14:19:22 +00006816- Bug #1637022: Prefix AST symbols with _Py_.
6817
6818- Fix some leftovers from the conversion from int to Py_ssize_t
6819 (relevant to strings and sequences of more than 2**31 items).
6820
6821- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6822 outside of pystate.c and should not be necessary.
6823
Georg Brandl3ee81df2008-05-17 18:14:43 +00006824- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6825 absolute imports. In earlier versions they might have used relative
6826 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006827
Georg Brandl3ee81df2008-05-17 18:14:43 +00006828- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6829 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006830
Georg Brandl3ee81df2008-05-17 18:14:43 +00006831- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6832 macro so it can be used as an expression.

6837
Georg Brandl3ee81df2008-05-17 18:14:43 +00006838- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6839 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6840 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6841 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006842
Georg Brandl3ee81df2008-05-17 18:14:43 +00006843- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
6844 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00006854- buildtools now raises a DeprecationWarning.
6855
Georg Brandl3ee81df2008-05-17 18:14:43 +00006856- Removed the macfs module. It had been deprecated since Python 2.5.
6857 This lead to the deprecation of macostools.touched() as it relied
6858 solely on macfs and was a no-op under OS X.
