316 SSLSocket.sendto() to match the corresponding socket methods. Also,
317 fix various SSLSocket methods to raise socket.error rather than an
318 unhelpful TypeError when called on an unconnected socket. Original patch
319 by Andrew Bennetts.

328
Raymond Hettinger20397532010-09-12 02:11:45 +0000329- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
330 This prevents user-created self-referencing ordered dictionaries from
331 becoming permanently uncollectable GC garbage. The downside is that
332 removing __del__ means that the internal doubly-linked list has to wait for
333 GC collection rather than freeing memory immediately when the refcnt drops
334 to zero.

343 original error is re-raised.

793 start byte and the continuation byte(s) are now considered invalid, instead
794 of the number of bytes specified by the start byte.
795 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
796 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

807 objects. (1) The comparison could incorrectly return True in some cases
808 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00001152- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001153 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1154 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1155 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1175Core and Builtins
1176-----------------
1177
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001178- Issue #7301: Add environment variable $PYTHONWARNINGS.
1179
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001180- Issue #8329: Don't return the same lists from select.select when no fds are
1181 changed.
1182
Georg Brandlfee0f442010-05-22 21:26:21 +00001183- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001184 on 64-bit machines. The shift count for either left or right shift is
1185 permitted to be up to sys.maxsize.
1186
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001187- Ensure that tokenization of identifiers is not affected by locale.
1188
Georg Brandlfee0f442010-05-22 21:26:21 +00001189- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001190
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001191- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1192
Georg Brandlfee0f442010-05-22 21:26:21 +00001193- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1194 with a non-empty format string. This is an effort to future-proof user
1195 code. If a derived class does not currently implement __format__ but later
1196 adds its own __format__, it would most likely break user code that had
1197 supplied a format string. This will be changed to a DeprecationWaring in
1198 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001199
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001200- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00001213- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001214 (SIGINT). If an error occurs while importing the site module, the error is
1215 printed and Python exits. Initialize the GIL before importing the site

1224
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001225- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001226 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

Benjamin Peterson76a23c12010-04-04 23:23:22 +00001229- Issue #8310: Allow dis to examine new style classes.
1230
Georg Brandlfee0f442010-05-22 21:26:21 +00001231- Issue #8257: The Decimal construct now accepts a float instance directly,
1232 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001233
1234 >>> Decimal(1.1)
1235 Decimal('1.100000000000000088817841970012523233890533447265625')
1236
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001237- collections.Counter() now supports a subtract() method.
1238
Georg Brandlfee0f442010-05-22 21:26:21 +00001239- The functools module now has a total_ordering() class decorator to simplify
1240 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001241
Georg Brandlfee0f442010-05-22 21:26:21 +00001242- The functools module also adds cmp_to_key() as a tool to transition old-style
1243 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001244
Georg Brandlfee0f442010-05-22 21:26:21 +00001245- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1246 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001247
Georg Brandlfee0f442010-05-22 21:26:21 +00001248- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1249 InvalidOperation instead of returning False. (Comparisons involving a quiet
1250 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1251 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001252
Georg Brandlfee0f442010-05-22 21:26:21 +00001253- Issue #2531: Comparison operations between floats and Decimal instances now
1254 return a result based on the numeric values of the operands; previously they
1255 returned an arbitrary result based on the relative ordering of id(float) and
1256 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001257
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001258- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001259 argument `-` which tells it to read files to compile from stdin. Each line is
1260 read on demand and the named file is compiled immediately. (Original patch by
1261 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001262
Georg Brandlfee0f442010-05-22 21:26:21 +00001263- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1264 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001266- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1267 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001268 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001269
Georg Brandlfee0f442010-05-22 21:26:21 +00001270- Comparisons using one of <, <=, >, >= between a complex instance and a
1271 Fractions instance now raise TypeError instead of returning True/False. This
1272 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1273 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001274
Michael Foorde6410c52010-03-29 20:04:23 +00001275- Addition of ``WeakSet`` to the ``weakref`` module.

1283
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001284- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001285 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1286 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001287
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001288- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1289 deprecated.
1290
Georg Brandlfee0f442010-05-22 21:26:21 +00001291- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001328- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001329 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1330 log file to compute the next rollover time. If the log file does not exist,
1331 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001332
Georg Brandlba83f822010-03-14 09:50:54 +00001333- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001341- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1342 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1343 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001372- Issue #8300: When passing a non-integer argument to struct.pack with any
1373 integer format code, struct.pack first attempts to convert the non-integer
1374 using its __index__ method. If that method is non-existent or raises
1375 TypeError it goes on to try the __int__ method, as described below.
1376
Georg Brandlba83f822010-03-14 09:50:54 +00001377- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1378 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1379 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001380 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1381 inconsistent: __int__ was used for some integer codes but not for others, and
1382 the set of integer codes for which it was used differed between native packing
1383 and standard packing.)

1615 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00001616 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00001635- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1636 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1637 returning NULL. The macro now returns a statically allocated empty string
1638 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00001691 file position when calling `truncate()`. It would previously change the file
1692 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001693 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1696 class used to represent files stored inside an archive. The new
1697 implementation is significantly faster and can be wrapped in a
1698 ``io.BufferedReader`` object for more speedups. It also solves an issue
1699 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1712 encoded string for them. This ensures that the upload and register commands
1713 send the correct values to PyPI without any error.

1788-----------------
1789
Georg Brandlba83f822010-03-14 09:50:54 +00001790- The ``__complex__()`` method is now looked up on the class of instances to
1791 make it consistent with other special methods.

1795
Mark Dickinson1b34d252010-01-01 17:27:30 +00001796- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001797 DeprecationWarning when passed a float argument where an integer was expected.
1798 These functions and methods now raise TypeError instead. The majority of the
1799 effects of this change are in the extension modules, but some core functions
1800 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1801 and many unicode/str methods.

1815 of integers: the result of a/b is now correctly rounded for ints a and b (at
1816 least on IEEE 754 platforms), and in particular does not depend on the
1817 internal representation of a long.

1825
Georg Brandlba83f822010-03-14 09:50:54 +00001826 These executables now work properly with the arch(1) command: ``arch -ppc
1827 python`` will start a universal binary version of python in PPC mode (unlike
1828 previous releases).

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001969

1971 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001972

Georg Brandlba83f822010-03-14 09:50:54 +00001984- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1985 decimal string that's guaranteed to round back to x under correct rounding
1986 (with round-half-to-even rounding mode). Previously it gave a string based on
1987 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1988 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1989 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001990
Georg Brandlba83f822010-03-14 09:50:54 +00001991- Issue #7117: On almost all platforms: float-to-string and string-to-float
1992 conversions within Python are now correctly rounded. Places these conversions
1993 occur include: str for floats and complex numbers; the float and complex
1994 constructors; old-style and new-style numeric formatting; serialization and
1995 deserialization of floats and complex numbers using marshal, pickle and json;
1996 parsing of float and imaginary literals in Python code; Decimal-to-float
1997 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001998
Georg Brandlba83f822010-03-14 09:50:54 +00001999 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2000 providing correctly-rounded strtod and dtoa C functions. This code is
2001 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2002 the C compiler. There may be a small number of platforms on which correct
2003 operation of this code cannot be guaranteed, so the code is not used: notably,
2004 this applies to platforms where the C double format is not IEEE 754 binary64,
2005 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2006 and Python's configure script is unable to determine how to change the FPU
2007 precision. On these platforms conversions use the platform strtod and dtoa,
2008 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002010- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2011 uses the correctly-rounded string <-> float conversions described above (when
2012 available), and so produces correctly rounded results that will display nicely
2013 under the float repr. There are two related small changes: (1) round now
2014 accepts any class with an ``__index__()`` method for its second argument (but
2015 no longer accepts floats for the second argument), and (2) an excessively
2016 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2017 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002159
Georg Brandlba83f822010-03-14 09:50:54 +00002160 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2161 (2) parsing of strings representing infinities and nans was locale aware; and
2162 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002164- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2165 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2166 but with at least one decimal point and with a default precision
2167 of 12. Previously, the behavior the same but with a default precision of 6.
2168 This more closely matches ``str()``, and reduces surprises when adding
2169 alignment flags to the empty presentation type. This also affects the new
2170 complex.__format__ in the same way.
2171
2172- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2173 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00002235 untrackable objects are not tracked by the garbage collector. This can reduce

2332
Georg Brandl6425a2f2008-12-28 11:54:53 +00002333- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002334 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002335
Skip Montanarof205c132008-12-23 03:30:15 +00002336- Added test case to ensure attempts to read from a file opened for writing
2337 fail.
2338
Georg Brandlba83f822010-03-14 09:50:54 +00002339- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print

Georg Brandlba83f822010-03-14 09:50:54 +00002353- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2354 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2355 instances. On a typical machine this saves 3 bytes of memory (on average) per
2356 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002358- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2359 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2360 instead of throwing a MemoryError.
2361
Georg Brandlba83f822010-03-14 09:50:54 +00002362- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00002365- Issue #4367: Python would segfault during compiling when the unicodedata

2367
Georg Brandlba83f822010-03-14 09:50:54 +00002368- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2369 file objects with closefd=False. The file descriptor is still kept open but
2370 the file object behaves like a closed file. The ``FileIO`` object also got a
2371 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002373- Issue #4348: Some bytearray methods returned that didn't cause any change to
2374 the bytearray, returned the same bytearray instead of a copy.
2375
Georg Brandlba83f822010-03-14 09:50:54 +00002376- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00002388- Issue #4209: Enabling unicode_literals and the print_function in the same
2389 __future__ import didn't work.
2390
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002391- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002392 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002393
Georg Brandlba83f822010-03-14 09:50:54 +00002394- On windows, ``os.chdir()`` given unicode was not working if
2395 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2396 this code path is really executed because I cannot move to such directory on
2397 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002398
Georg Brandlba83f822010-03-14 09:50:54 +00002399- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2400 element is temporarily replaced with an equivalent frozenset. But the
2401 eventual KeyError would always report the empty ``frozenset()`` as the missing
2402 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00002419- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
2420 returned them on 64bit platforms.
2421
Walter Dörwalded960ac2009-05-03 22:36:33 +00002422- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2423 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2424 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2425 of using the replace error handler in PyUnicode_DecodeUTF8().
2426
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002427- Issue #3739: The unicode-internal encoder now reports the number of characters
2428 consumed like any other encoder (instead of the number of bytes).
2429
Georg Brandlba83f822010-03-14 09:50:54 +00002430- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2431 allocator will be automatically disabled when running under Valgrind. This
2432 gives improved memory leak detection when running under Valgrind, while taking
2433 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003677 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3678 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00003683- Issue #5354: New test support function import_fresh_module() makes it easy to
3684 import both normal and optimised versions of modules. test_heapq and
3685 test_warnings have been adjusted to use it, tests for other modules with both
3686 C and Python implementations in the stdlib can be adjusted to use it over
3687 time.

3697 support, which does the conversion.

3799
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003800- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3801 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3802 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3803 ``printf`` function, whereas PyString_FromFormat has an independent
3804 implementation and uses "%zd" on all platforms for size_t values.
3805 This makes a difference on win64, where ``printf`` needs "%Id" to display
3806 64bit values.

3812 object; previously an int would be returned for small values. the __long__
3813 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003823 was correctly parsed but parsing of subsequent arguments failed.
3824
Vinay Sajip35e3b032008-09-01 14:33:59 +00003825- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003826 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3827 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3828 when given a tuple of classes as second argument, were looking up
3829 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3830 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003969What's New in Python 2.6 beta 3?
3970================================
3971
Barry Warsaw07a4a382008-08-21 01:15:08 +00003972*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003973
3974Core and Builtins
3975-----------------
3976
Guido van Rossumf8402962008-08-20 15:01:50 +00003977- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3978 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3979 extensions do not automatically benefit from the class attribute
3980 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3981 to their tp_flags field if they care. This is a backwards
3982 compatibility feature; in 3.0, all types will use the cache by
3983 default.
3984
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003985- Keyword arguments can now follow starred arguments. (``f(a, *args,
3986 keyword=23)`` is now valid syntax.)
3987
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003988- ctypes function pointers that are COM methods have a boolean True
3989 value again.
3990
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003991- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3992 by denying s# to parse objects that have a releasebuffer procedure,
3993 and introducing s*.
3994
Georg Brandl1e13ea92008-08-11 09:07:59 +00003995- Issue #3537: Fix an assertion failure when an empty but presized dict
3996 object was stored in the freelist.
3997
Mark Dickinsonb6467572008-08-04 21:30:09 +00003998- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3999 ValueError consistently across platforms.
4000
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004001- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4002 (64bit Unix, for example), unichr() would truncate its argument and return
4003 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4004
Neal Norwitze7d8be82008-07-31 17:17:14 +00004005- Apply security patches from Apple.
4006
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004007- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4008 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4009
Antoine Pitrou92f82162008-07-25 22:22:08 +00004010- Issue #1819: function calls with several named parameters are now on
4011 average 35% faster (as measured by pybench).
4012
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004013- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4014 the python debugger steps into a class statement: the free variables (local
4015 variables defined in an outer scope) would be deleted from the outer scope.
4016
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004017- Issue #2620: Overflow checking when allocating or reallocating memory
4018 was not always being done properly in some python types and extension
4019 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4020 all been updated to perform better checks and places in the code that
4021 would previously leak memory on the error path when such an allocation
4022 failed have been fixed.
4023
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004024Library
4025-------
4026
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004027- Issue #3612: Added some missing basic types in ctypes.wintypes.
4028
Benjamin Petersone977ad42008-08-20 01:42:01 +00004029- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4030 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4031
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004032- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4033 version reported by these tools does not necessarily follow the python
4034 version numbering scheme, so the module is less strict when parsing it.
4035
Nick Coghlanf70385a2008-08-18 12:42:46 +00004036- Issue #2235: Added Py3k warnings for types which will become unhashable
4037 under the stricter __hash__ inheritance rules in 3.0. Several types
4038 which did not meet the rules for hash invariants and were already
4039 unhashable in 3.0 have now been explicitly flagged as unhashable in
4040 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4041 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4042
Brett Cannon88f801d2008-08-18 00:46:22 +00004043- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4044 imported into the module but exposed as part of the module's API.
4045
Brett Cannon7b96f072008-08-18 00:41:11 +00004046- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4047
Brett Cannon46225e72008-08-18 00:36:52 +00004048- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4049
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004050- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4051
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004052- Issue #3575: Incremental decoder's decode function now takes bytearray
4053 by using 's*' instead of 't#'.
4054
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004055- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004056 fails unicode conversion on 2nd parameter. (windows only)
4057
Georg Brandl222e2082010-08-01 22:27:39 +00004058- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004059 in a redirect.
4060
Brett Cannonabe423e2008-08-16 21:47:07 +00004061- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004062 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004063
Facundo Batistaeb90b782008-08-16 14:44:07 +00004064- Issue #2776: fixed small issue when handling an URL with double slash
4065 after a 302 response in the case of not going through a proxy.
4066
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004067- Issue #2676: in the email package, content-type parsing was hanging on
4068 pathological input because of quadratic or exponential behaviour of a
4069 regular expression.
4070
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004071- Issue #3476: binary buffered reading through the new "io" library is now
4072 thread-safe.
4073
Brett Cannonbf3157b2008-08-14 05:00:03 +00004074- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4075 since mimetools itself is deprecated. Because modules are cached, all
4076 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4077
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004078- Issue #3134: shutil referenced undefined WindowsError symbol.
4079
Robert Schuppenies14646332008-08-10 11:01:53 +00004080- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4081 menu entries were not deleted.
4082
Brett Cannon83e81842008-08-09 23:30:55 +00004083- Copied the implementation of reduce() to _functools.reduce() to have a
4084 version that did not raise a DeprecationWarning under -3.
4085
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004086- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4087 a MemoryError rather than silently stop the iteration.
4088
Guido van Rossum59ce9012008-08-09 14:55:34 +00004089- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4090 to _sre.compile() will now be rejected. This should not affect anybody
4091 since the re.compile() function never generates invalid re-bytecode.
4092
Skip Montanaroa032bf42008-08-08 22:52:51 +00004093- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4094 upon first access it can be automatically initialized from the csv file if
4095 it wasn't initialized during instantiation.
4096
Brett Cannon3aa2a492008-08-06 22:28:09 +00004097- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4098 the reload() built-in has been removed.
4099
Brett Cannon7e30b672008-08-04 21:52:25 +00004100- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004101 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004102 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4103 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4104 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4105 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4106 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004107
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004108- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4109 raised an AttributeError.
4110
Benjamin Peterson01a24322008-07-28 23:35:27 +00004111- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004112 asking for a specific length. This problem only affected files opened
4113 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004114
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004115- Issue #3449: Update decimal module to use most recent specification
4116 (v. 1.68) and tests (v. 2.58) from IBM.
4117
Georg Brandl222e2082010-08-01 22:27:39 +00004118- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004119

4122
Georg Brandlf9efabb2008-07-23 15:16:45 +00004123- Deprecate the "ast" parser function aliases.
4124
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004125- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4126
4127- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4128 invalid arguments.
4129
4130- Issue #3302: Fix several crashes when calling locale's gettext functions
4131 with None arguments.
4132
4133- Issue #3389: Allow resolving dotted names for handlers in logging
4134 configuration files.
4135

4137
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004138- Issue #3394: zipfile.writestr sets external attributes when passed a
4139 file name rather than a ZipInfo instance, so files are extracted with
4140 mode 0600 rather than 000 under Unix.
4141
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004142- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4143 argument in python 2.5, this broke code that subclassed Popen to include its
4144 own poll method. Fixed my moving _deadstate to an _internal_poll method.
4145
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00004146Build
4147-----

4152-------------
4153
Nick Coghlan6e8fef02008-08-18 13:14:22 +00004154- Issue #2235: the C API function PyObject_HashNotImplemented and its
4155 interaction with the tp_hash slot (added in 2.6b2) are now documented
4156
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004157- Issue #643841: The language reference now provides more detailed
4158 coverage of the lookup process for special methods. The disclaimers
4159 regarding lack of coverage of new-style classes have also been
4160 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004163What's New in Python 2.6 beta 2?
4164================================
4165
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004166*Release date: 17-Jul-2008*
4167
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004168Core and Builtins
4169-----------------
4170
Georg Brandl3e483f62008-07-16 22:57:41 +00004171- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4172 its methods now allow for items objects that can be converted to
4173 an integer using operator.index().
4174
Mark Dickinson64b7e502008-07-16 09:40:03 +00004175- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4176 produced a ValueError instead of giving the correct float.
4177
Eric Smitha5fa5a22008-07-16 00:11:49 +00004178- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4179 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4180
Mark Dickinson7103aa42008-07-15 19:08:33 +00004181- Issue #3008: the float type has a new instance method 'float.hex'
4182 and a new class method 'float.fromhex' to convert floating-point
4183 numbers to and from hexadecimal strings, respectively.
4184
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004185- Issue #2235: __hash__ is once again inherited by default. To allow
4186 collections.Hashable to remain meaningful in the presence of the
4187 default hash implementation (object.__hash__), it is now possible
4188 to explicit block inheritance of hash by setting __hash__=None at
4189 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4190 level.
4191
Nick Coghlanb028f502008-07-13 14:52:36 +00004192- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4193 the parent module cannot be found while performing an absolute import.
4194 This means that an incorrectly defined __package__ attribute will
4195 now only prevent relative imports in that module rather than causing
4196 all imports from that module to fail.
4197
Nick Coghlan14ff9942008-07-08 14:21:42 +00004198- Issue #2517: Allow unicode messages in Exceptions again by correctly
4199 bypassing the instance dictionary when looking up __unicode__ on
4200 new-style classes.
4201
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004202- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4203 set to a custom object whose write() method happens to install
4204 another file in sys.stdout.
4205
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004206- Issue #3088: Corrected a race condition in classes derived from
4207 threading.local: the first member set by a thread could be saved in
4208 another thread's dictionary.
4209
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004210- Issue #3004: Minor change to slice.indices(): the start and stop
4211 arguments are now treated identically, making the behaviour easier
4212 to describe and understand. For example, slice(None, -10,
4213 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4214 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4215 10, -1).
4216
Georg Brandl278fc502008-07-19 12:46:12 +00004217- Issue #3219: Calling a function with repeated keyword arguments,
4218 f(a=2, a=23), would not cause a syntax error. This was a regression
4219 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004220
Georg Brandl278fc502008-07-19 12:46:12 +00004221- Issue #2862: Make int and float freelist management consistent with
4222 other freelists. Changes their CompactFreeList apis into
4223 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004224

4227
Thomas Heller57adf222008-08-14 19:10:48 +00004228- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4229 api functions without holding the GIL, which could lead to a fatal
4230 error when they failed.
4231
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004232- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4241 ForkingPickler.register() to resolve conflict with ctypes.
4242
Vinay Sajip51e65192008-07-18 09:01:10 +00004243- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

4246 a valid dlerror() message.
4247
Thomas Heller2bad6572008-07-15 17:19:50 +00004248- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4249 incomplete structure was created.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00004253- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4254

4668 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004669 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004670
4671 This is controlled by the configure argument ``--with-universal-archs``:
4672
4673 - ``--with-universal-archs=all``: install 4-way universal
4674
4675 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4676
4677 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4678
4679 This option should be used in combination with ``--enable-universalsdk=``.
4680
4681 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

4718 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00004719
Christian Heimese74c8f22008-04-19 02:23:57 +00004720- Added kill, terminate and send_signal(sig) to subprocess.Popen.
4721
Georg Brandl3ee81df2008-05-17 18:14:43 +00004722- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
4723 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00004724

Georg Brandl3ee81df2008-05-17 18:14:43 +00004731- Issue #1631171: Re-implement the 'warnings' module in C (the
4732 original Python code has been kept as backup). This will allow for
4733 using the 'warning's machinery in such places as the parser where
4734 use of pure Python code is not possible. Both the ``showarning()``
4735 and ``formatwarning()`` gain an optional 'line' argument which is
4736 not called by default for backwards-compatibility reasons. Setting
4737 ``warnings.showwarning()`` to an implementation that lacks support
4738 for the ``line`` argument will raise a DeprecationWarning.

4762
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004763- The getpass module has been improved on Unix. It now uses /dev/tty
4764 by default and uses stderr instead of stdout. A GetPassWarning is
4765 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004766

Georg Brandl3ee81df2008-05-17 18:14:43 +00004780- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004781 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004801- Issue #2550: The approach used by client/server code for obtaining
4802 ports to listen on in network-oriented tests has been refined in an
4803 effort to facilitate running multiple instances of the entire
4804 regression test suite in parallel without issue.
4805 test_support.bind_port() has been fixed such that it will always
4806 return a unique port -- which wasn't always the case with the
4807 previous implementation, especially if socket options had been set
4808 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4809 new implementation of bind_port() will actually raise an exception
4810 if it is passed an AF_INET/SOCK_STREAM socket with either the
4811 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4812 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4813 the socket it's been passed. This currently only applies to
4814 Windows. This option prevents any other sockets from binding to the
4815 host/port we've bound to, thus removing the possibility of the
4816 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4817 when a second SOCK_STREAM socket binds and accepts to a host/port
4818 that's already been bound by another socket. The optional preferred
4819 port parameter to bind_port() has been removed. Under no
4820 circumstances should tests be hard coding ports!
4821
4822 test_support.find_unused_port() has also been introduced, which will
4823 pass a temporary socket object to bind_port() in order to obtain an
4824 unused port. The temporary socket object is then closed and
4825 deleted, and the port is returned. This method should only be used
4826 for obtaining an unused port in order to pass to an external program
4827 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4828 a parameter to a server-oriented class that doesn't give you direct
4829 access to the underlying socket used.
4830
4831 Finally, test_support.HOST has been introduced, which should be used
4832 for the host argument of any relevant socket calls (i.e. bind and
4833 connect).

5109
Fred Drakea8ee94b2008-03-01 02:45:07 +00005110- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005111 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005112
Georg Brandlad61bc82008-02-23 15:11:18 +00005113- Issue #2067: file.__exit__() now calls subclasses' close() method.
5114
5115- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005116
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005117- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005118 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005119
Eric Smitha73fbe72008-02-23 03:09:44 +00005120- Added the future_builtins module, which contains hex() and oct().
5121 These are the PEP 3127 version of these functions, designed to be
5122 compatible with the hex() and oct() builtins from Python 3.0. They
5123 differ slightly in their output formats from the existing, unchanged
5124 Python 2.6 builtins. The expected usage of the future_builtins
5125 module is:
5126 from future_builtins import hex, oct
5127
Eric Smith7ef40bf2008-02-20 23:34:22 +00005128- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5129 exponents for exponents with absolute value < 100. Follows C99
5130 standard. This is a change on Windows, which would use 3 digits.
5131 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5132 so that any alterations it does to the resulting string will be
5133 available in stringlib/formatter.h (for float.__format__).
5134
Eric Smith5a3c1352008-02-19 13:21:56 +00005135- Implemented PEP 3101, Advanced String Formatting. This adds a new
5136 builtin format(); a format() method for str and unicode; a
5137 __format__() method to object, str, unicode, int, long, float, and
5138 datetime; the class string.Formatter; and the C API
5139 PyObject_Format().
5140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- Fixed several potential crashes, all caused by specially crafted
5142 __del__ methods exploiting objects in temporarily inconsistent
5143 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005144
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005145- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005146 prevent a possible crash: an Abstract Base Class would try to access
5147 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005148
Georg Brandl3ee81df2008-05-17 18:14:43 +00005149- Fixed repr() and str() of complex numbers with infinity or nan as
5150 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005151
Georg Brandl3ee81df2008-05-17 18:14:43 +00005152- Clear all free lists during a gc.collect() of the highest generation
5153 in order to allow pymalloc to free more arenas. Python may give back
5154 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005155
Georg Brandl3ee81df2008-05-17 18:14:43 +00005156- Issue #2045: Fix an infinite recursion triggered when printing a
5157 subclass of collections.defaultdict, if its default_factory is set
5158 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005159
Christian Heimesf75dbef2008-02-08 00:11:31 +00005160- Fixed a minor memory leak in dictobject.c. The content of the free
5161 list was not freed on interpreter shutdown.
5162
Georg Brandl21e99f42010-03-07 15:23:59 +00005163- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005164 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005165
Georg Brandl3ee81df2008-05-17 18:14:43 +00005166- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5167 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005168 to compact the internal free lists of pre-allocted ints and floats.
5169
Georg Brandl3ee81df2008-05-17 18:14:43 +00005170- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5171 calls. Python expected the return type int but the fork familie
5172 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005173
Georg Brandl3ee81df2008-05-17 18:14:43 +00005174- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5175 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005176
Georg Brandl3ee81df2008-05-17 18:14:43 +00005177- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5178 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005179
Georg Brandl3ee81df2008-05-17 18:14:43 +00005180- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5181 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005182
Georg Brandl3ee81df2008-05-17 18:14:43 +00005183- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5184 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005185
Georg Brandl3ee81df2008-05-17 18:14:43 +00005186- Patch #1473257: generator objects gain a gi_code attribute. This is
5187 the same object as the func_code attribute of the function that
5188 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005189
Georg Brandl3ee81df2008-05-17 18:14:43 +00005190- Issue #1920: "while 0" statements were completely removed by the
5191 compiler, even in the presence of an "else" clause, which is
5192 supposed to be run when the condition is false. Now the compiler
5193 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005194
Guido van Rossumeead05f2008-01-24 18:21:02 +00005195- A few crashers fixed: weakref_in_del.py (issue #1377858);
5196 loosing_dict_ref.py (issue #1303614, test67.py);
5197 borrowed_ref_[34].py (not in tracker).
5198
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005199- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005200 suppressed while an extension is loaded by calling SetErrorMode in
5201 dynload_win.c. The error is still reported properly.
5202
Georg Brandl3ee81df2008-05-17 18:14:43 +00005203- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005204 several extension methods and modules do not work without unicode
5205 support.
5206
Georg Brandl26543b12008-01-21 18:36:51 +00005207- Issue #1882: when compiling code from a string, encoding cookies in the
5208 second line of code were not always recognized correctly.
5209
Georg Brandl14404b62008-01-19 19:27:05 +00005210- Issue #1679: "0x" was taken as a valid integer literal.
5211
Georg Brandl6caad7d2008-01-26 14:19:22 +00005212- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005213 added.
5214
Christian Heimesc94e2b52008-01-14 04:13:37 +00005215- sys.float_info / PyFloat_GetInfo: The floating point information
5216 object was converted from a dict to a specialized structseq object.
5217
Georg Brandl3ee81df2008-05-17 18:14:43 +00005218- Patch #1816: Added sys.flags structseq. It exposes the status of
5219 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005220
Georg Brandl3ee81df2008-05-17 18:14:43 +00005221- Objects/structseq.c: Implemented new structseq representation. The
5222 patch makes structseqs (e.g. the return value of os.stat) more
5223 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005224
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225- Patch #1700288: added a type attribute cache that caches method
5226 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005227
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005228- Bug #1776: __import__() no longer accepts filenames on any platform.
5229 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005230

5232
Georg Brandl3ee81df2008-05-17 18:14:43 +00005233- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5234 envvar and sys.dont_write_bytecode attribute. All these can be set
5235 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005236
Georg Brandl3ee81df2008-05-17 18:14:43 +00005237- Improve some exception messages when Windows fails to load an
5238 extension module. Now we get for example '%1 is not a valid Win32
5239 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005240
Georg Brandl3ee81df2008-05-17 18:14:43 +00005241- Bug #1481296: Fixed long(float('nan')) != 0L.

5244 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005245
Christian Heimes0a8143f2007-12-18 23:22:54 +00005246- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005247 and INF. float("nan"), float("inf") and float("-inf") now work on
5248 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005249
Georg Brandl3ee81df2008-05-17 18:14:43 +00005250- Compiler now generates simpler and faster code for dictionary
5251 literals. The oparg for BUILD_MAP now indicates an estimated
5252 dictionary size. There is a new opcode, STORE_MAP, for adding
5253 entries to the dictionary.

5285 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005286
Georg Brandl3ee81df2008-05-17 18:14:43 +00005287- Issue #1265: Fix a problem with sys.settrace, if the tracing
5288 function uses a generator expression when at the same time the
5289 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005290
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005291- sets and frozensets now have an isdisjoint() method.

5296
Georg Brandl21e99f42010-03-07 15:23:59 +00005297- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005298 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5299 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005300
Georg Brandl3ee81df2008-05-17 18:14:43 +00005301- Issue #1686386: Tuple's tp_repr did not take into account the
5302 possibility of having a self-referential tuple, which is possible
5303 from C code. Nor did object's tp_str consider that a type's tp_str
5304 could do something that could lead to an inifinite recursion.
5305 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5306 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005307
Georg Brandl3ee81df2008-05-17 18:14:43 +00005308- Issue #1164: It was possible to trigger deadlock when using the
5309 'print' statement to write to a file since the GIL was not released
5310 as needed. Now PyObject_Print() does the right thing along with
5311 various tp_print implementations of the built-in types and those in
5312 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005314- Issue #1147: Exceptions were directly allowing string exceptions in
5315 their throw() method even though string exceptions no longer
5316 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005318- Issue #1096: Prevent a segfault from getting the repr of a very
5319 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00005321- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005322 PyObject_Call() never calling back out to Python code to trigger
5323 recursion depth updates/checks. Required the creation of a static
5324 RuntimeError instance in case normalizing an exception put the
5325 recursion check value past its limit. Fixes crashers
5326 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005341- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005342 __*__ attributes. (Some already existed, e.g., __doc__ and
5343 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005344
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005345- Add -3 option to the interpreter to warn about features that are

5349 calls.
5350
Collin Winter62903052007-05-18 23:11:24 +00005351- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005352 "except E as target:". This is to provide forwards compatibility
5353 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005354
Brett Cannon229cee22007-05-05 01:34:02 +00005355- Deprecate BaseException.message as per PEP 352.
5356
Georg Brandl3ee81df2008-05-17 18:14:43 +00005357- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00005360- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005361 setting a plain string, ie don't expand to single letter identifiers.
5362
Raymond Hettinger13936692007-04-11 18:40:58 +00005363- Request #1191699: Slices can now be pickled.
5364
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005365- Request #1193128: str.translate() now allows a None argument for
5366 translations that only remove characters without re-mapping the
5367 remaining characters.
5368
Georg Brandl5cb76c12007-03-21 09:00:39 +00005369- Patch #1682205: a TypeError while unpacking an iterable is no longer

5371
Neal Norwitzaa754b72007-03-21 06:39:48 +00005372- Remove unused file Python/fmod.c.
5373
Guido van Rossum143b5642007-03-23 04:58:42 +00005374- Bug #1683368: The object.__init__() and object.__new__() methods are
5375 now stricter in rejecting excess arguments. The only time when
5376 either allows excess arguments is when it is not overridden and the
5377 other one is. For backwards compatibility, when both are
5378 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005379 warning later). Also, type.__init__() insists on the same signature
5380 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005381
Georg Brandl3ee81df2008-05-17 18:14:43 +00005382- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5383 object to complex using its __complex__() method before falling back
5384 to the __float__() method. Therefore, the functions in the cmath
5385 module now can operate on objects that define a __complex__()
5386 method.

5397 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005404- Bug #1678647: write a newline after printing an exception in any
5405 case, even when converting the value to a string failed.
5406
Georg Brandl871f1bc2007-03-12 13:17:36 +00005407- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005408 its argument, if it exists. If not, it will work like before. This
5409 allows customizing the output of dir() in the presence of a
5410 __getattr__().

5419 parthensized forms. This means complex(repr(x)) now works instead of
5420 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005421
Georg Brandlaa2321b2007-03-07 00:40:28 +00005422- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005423 makes the filenames the warning module prints much more sensible
5424 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005425

5427 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005428 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00005437- Patch #1674228: when assigning a slice (old-style), check for the
5438 sq_ass_slice instead of the sq_slice slot.
5439
Georg Brandl3ee81df2008-05-17 18:14:43 +00005440- When printing an unraisable error, don't print exceptions. before
5441 the name. This duplicates the behavior whening normally printing
5442 exceptions.

6051 Python would crash instead of raising an error.
6052

6068 accepted in TestSuite.addTest(). This should cause no
6069 incompatibility since it never made sense with ordinary subclasses
6070 -- the failure just occurred later, with a more cumbersome
6071 exception.

6354 obtained from the TLS negotiation itself. Patch contributed by Bill
6355 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006356
Georg Brandl3ee81df2008-05-17 18:14:43 +00006357- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006358 that the SMTP.starttls() caller no longer needs to call ehlo()
6359 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006360 does not claim to support starttls. Adds the
6361 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6442 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6443 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00006460 time so that opening a database previously created with the DB_DUP
6461 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6462 opens. Specifically: dictionary assignment to a DB object will
6463 replace all values for a given key when the database allows
6464 duplicate values. DB users should use DB.put(k, v) when they want
6465 to store duplicates; not DB[k] = v.

6472 characters with ASCII value less than 32. Also, it correctly quotes
6473 dots only if they occur on a single line, as opposed to the previous
6474 behavior of quoting dots if they are the second character of any
6475 line.

6798-----
6799
Georg Brandl3ee81df2008-05-17 18:14:43 +00006800- Unified naming convention for free lists and their limits. All free
6801 lists in Object/ are named ``free_list``, the counter ``numfree``
6802 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6803 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006804
Georg Brandl3ee81df2008-05-17 18:14:43 +00006805- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6806 to ``PyTuple_SetItem``, it can be used to populate a brand new
6807 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006808
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006809- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006811- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6812 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6813 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006814
6815- Patch #1720595: add T_BOOL to the range of structmember types.
6816
6817- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6818 ``PyFloat_GetInfo()`` to the float API.
6819
Georg Brandl3ee81df2008-05-17 18:14:43 +00006820- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6821 of w# format code incorrectly truncated the length to an int, even
6822 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6823 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006824
Georg Brandl3ee81df2008-05-17 18:14:43 +00006825- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6826 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006827
Georg Brandl3ee81df2008-05-17 18:14:43 +00006828- PEP 3123: Provide forward compatibility with Python 3.0, while
6829 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6830 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006831
Georg Brandl3ee81df2008-05-17 18:14:43 +00006832- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6833 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006834
6835- Patch #1733960: Allow T_LONGLONG to accept ints.
6836
6837- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6838
Christian Heimes000a0742008-01-03 22:16:32 +00006839- Added a new API function ``PyImport_ImportModuleNoBlock``.

6842
6843- Fix some leftovers from the conversion from int to Py_ssize_t
6844 (relevant to strings and sequences of more than 2**31 items).
6845
6846- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6847 outside of pystate.c and should not be necessary.
6848
Georg Brandl3ee81df2008-05-17 18:14:43 +00006849- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6850 absolute imports. In earlier versions they might have used relative
6851 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006852
Georg Brandl3ee81df2008-05-17 18:14:43 +00006853- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6854 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006855
Georg Brandl3ee81df2008-05-17 18:14:43 +00006856- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6857 macro so it can be used as an expression.

6862
Georg Brandl3ee81df2008-05-17 18:14:43 +00006863- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6864 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6865 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6866 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006867
Georg Brandl3ee81df2008-05-17 18:14:43 +00006868- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00006881- Removed the macfs module. It had been deprecated since Python 2.5.
6882 This lead to the deprecation of macostools.touched() as it relied
6883 solely on macfs and was a no-op under OS X.
