338 SSLSocket.sendto() to match the corresponding socket methods. Also,
339 fix various SSLSocket methods to raise socket.error rather than an

341 by Andrew Bennetts.

350
Raymond Hettinger20397532010-09-12 02:11:45 +0000351- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
352 This prevents user-created self-referencing ordered dictionaries from
353 becoming permanently uncollectable GC garbage. The downside is that
354 removing __del__ means that the internal doubly-linked list has to wait for
355 GC collection rather than freeing memory immediately when the refcnt drops
356 to zero.
357

364 to fetch the original errno, or to filter timeout errors. Now the
365 original error is re-raised.
366

Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000377- Issue #808164: Fixed socket.close to avoid references to globals, to

386
R. David Murray7c4bf552010-08-25 01:45:57 +0000387- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
388 character years even if the message contains RFC822 two character years.
389
Daniel Stutzbach91287322010-08-24 21:09:30 +0000390- Issue #8750: Fixed MutableSet's methods to correctly handle
391 reflexive operations, namely x -= x and x ^= x.
392

402 module now correctly return a set. (Patch by Eli Bendersky.)
403
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000404- Issue #9617: Signals received during a low-level write operation aren't
405 ignored by the buffered IO layer anymore.
406
Benjamin Peterson52c36052010-08-21 03:03:22 +0000407- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
408 are not held onto after they are deleted elsewhere.
409
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000410- Issue #9626: the view methods for collections.OrderedDict() were returning

423 original read request had been satisfied, which could block indefinitely
424 when the underlying raw IO channel was e.g. a socket. Report and original
425 patch by Jason V. Miller.

1197Core and Builtins
1198-----------------
1199
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001200- Issue #7301: Add environment variable $PYTHONWARNINGS.
1201
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001202- Issue #8329: Don't return the same lists from select.select when no fds are
1203 changed.
1204
Georg Brandlfee0f442010-05-22 21:26:21 +00001205- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001206 on 64-bit machines. The shift count for either left or right shift is
1207 permitted to be up to sys.maxsize.
1208
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001209- Ensure that tokenization of identifiers is not affected by locale.
1210
Georg Brandlfee0f442010-05-22 21:26:21 +00001211- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001213- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1214
Georg Brandlfee0f442010-05-22 21:26:21 +00001215- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1216 with a non-empty format string. This is an effort to future-proof user
1217 code. If a derived class does not currently implement __format__ but later
1218 adds its own __format__, it would most likely break user code that had
1219 supplied a format string. This will be changed to a DeprecationWaring in
1220 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001221
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001222- Issue #8268: Old-style classes (not just instances) now support weak

1234
Victor Stinner66644262010-03-10 22:30:19 +00001235- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001236 (SIGINT). If an error occurs while importing the site module, the error is

Antoine Pitrouf9de5342010-04-05 21:35:07 +00001247- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001248 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

1252
Georg Brandlfee0f442010-05-22 21:26:21 +00001253- Issue #8257: The Decimal construct now accepts a float instance directly,
1254 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001255
1256 >>> Decimal(1.1)
1257 Decimal('1.100000000000000088817841970012523233890533447265625')
1258
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001259- collections.Counter() now supports a subtract() method.
1260
Georg Brandlfee0f442010-05-22 21:26:21 +00001261- The functools module now has a total_ordering() class decorator to simplify
1262 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001263
Georg Brandlfee0f442010-05-22 21:26:21 +00001264- The functools module also adds cmp_to_key() as a tool to transition old-style
1265 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001266
Georg Brandlfee0f442010-05-22 21:26:21 +00001267- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1268 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001269
Georg Brandlfee0f442010-05-22 21:26:21 +00001270- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1271 InvalidOperation instead of returning False. (Comparisons involving a quiet
1272 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1273 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001274
Georg Brandlfee0f442010-05-22 21:26:21 +00001275- Issue #2531: Comparison operations between floats and Decimal instances now
1276 return a result based on the numeric values of the operands; previously they
1277 returned an arbitrary result based on the relative ordering of id(float) and
1278 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001279
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001280- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001281 argument `-` which tells it to read files to compile from stdin. Each line is
1282 read on demand and the named file is compiled immediately. (Original patch by
1283 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001284
Georg Brandlfee0f442010-05-22 21:26:21 +00001285- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001288- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1289 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001290 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001291
Georg Brandlfee0f442010-05-22 21:26:21 +00001292- Comparisons using one of <, <=, >, >= between a complex instance and a
1293 Fractions instance now raise TypeError instead of returning True/False. This
1294 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1295 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001296

1305
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001306- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001307 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1308 silenced.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001350- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001351 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1352 log file to compute the next rollover time. If the log file does not exist,
1353 the current time is used as the basis for the computation.

Georg Brandlfee0f442010-05-22 21:26:21 +00001402 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1403 inconsistent: __int__ was used for some integer codes but not for others, and
1404 the set of integer codes for which it was used differed between native packing
1405 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001617- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
1618 now also used by regrtest to run all the tests in a temporary directory. The
1619 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
1620 Xicluna who helped with the patch.

Georg Brandlba83f822010-03-14 09:50:54 +00001713 file position when calling `truncate()`. It would previously change the file
1714 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001715 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1716

1718 class used to represent files stored inside an archive. The new
1719 implementation is significantly faster and can be wrapped in a
1720 ``io.BufferedReader`` object for more speedups. It also solves an issue
1721 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1722 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001732- Issue #7748: Since unicode values are supported for some metadata options in
1733 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1734 encoded string for them. This ensures that the upload and register commands
1735 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002006- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2007 decimal string that's guaranteed to round back to x under correct rounding
2008 (with round-half-to-even rounding mode). Previously it gave a string based on
2009 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2010 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2011 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002012
Georg Brandlba83f822010-03-14 09:50:54 +00002013- Issue #7117: On almost all platforms: float-to-string and string-to-float
2014 conversions within Python are now correctly rounded. Places these conversions
2015 occur include: str for floats and complex numbers; the float and complex
2016 constructors; old-style and new-style numeric formatting; serialization and
2017 deserialization of floats and complex numbers using marshal, pickle and json;
2018 parsing of float and imaginary literals in Python code; Decimal-to-float
2019 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002020
Georg Brandlba83f822010-03-14 09:50:54 +00002021 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2022 providing correctly-rounded strtod and dtoa C functions. This code is
2023 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2024 the C compiler. There may be a small number of platforms on which correct
2025 operation of this code cannot be guaranteed, so the code is not used: notably,
2026 this applies to platforms where the C double format is not IEEE 754 binary64,
2027 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2028 and Python's configure script is unable to determine how to change the FPU
2029 precision. On these platforms conversions use the platform strtod and dtoa,
2030 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002032- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2033 uses the correctly-rounded string <-> float conversions described above (when
2034 available), and so produces correctly rounded results that will display nicely
2035 under the float repr. There are two related small changes: (1) round now
2036 accepts any class with an ``__index__()`` method for its second argument (but
2037 no longer accepts floats for the second argument), and (2) an excessively
2038 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2039 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002186- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2187 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2188 but with at least one decimal point and with a default precision
2189 of 12. Previously, the behavior the same but with a default precision of 6.
2190 This more closely matches ``str()``, and reduces surprises when adding
2191 alignment flags to the empty presentation type. This also affects the new
2192 complex.__format__ in the same way.
2193
2194- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00002257 untrackable objects are not tracked by the garbage collector. This can reduce

2325 collecting the oldest generation) so that allocating lots of objects without

2331
Georg Brandlba83f822010-03-14 09:50:54 +00002332- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2333 existing .py counterpart, override the co_filename attributes of all code
2334 objects if the original filename is obsolete (which can happen if the file has
2335 been renamed, moved, or if it is accessed through different paths). Patch by
2336 Ziga Seilnacht and Jean-Paul Calderone.

Georg Brandl6425a2f2008-12-28 11:54:53 +00002355- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002356 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.

Georg Brandlba83f822010-03-14 09:50:54 +00002375- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2376 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2377 instances. On a typical machine this saves 3 bytes of memory (on average) per
2378 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002380- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2382 instead of throwing a MemoryError.
2383
Georg Brandlba83f822010-03-14 09:50:54 +00002384- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00002387- Issue #4367: Python would segfault during compiling when the unicodedata

2389
Georg Brandlba83f822010-03-14 09:50:54 +00002390- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2391 file objects with closefd=False. The file descriptor is still kept open but
2392 the file object behaves like a closed file. The ``FileIO`` object also got a
2393 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002395- Issue #4348: Some bytearray methods returned that didn't cause any change to
2396 the bytearray, returned the same bytearray instead of a copy.
2397
Georg Brandlba83f822010-03-14 09:50:54 +00002398- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00002410- Issue #4209: Enabling unicode_literals and the print_function in the same
2411 __future__ import didn't work.
2412
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002413- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002414 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002416- On windows, ``os.chdir()`` given unicode was not working if
2417 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2418 this code path is really executed because I cannot move to such directory on
2419 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002420
Georg Brandlba83f822010-03-14 09:50:54 +00002421- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2422 element is temporarily replaced with an equivalent frozenset. But the
2423 eventual KeyError would always report the empty ``frozenset()`` as the missing
2424 key. Now it correctly refers to the initial element.

2442 returned them on 64bit platforms.
2443
Walter Dörwalded960ac2009-05-03 22:36:33 +00002444- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2445 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2446 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2447 of using the replace error handler in PyUnicode_DecodeUTF8().
2448
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002449- Issue #3739: The unicode-internal encoder now reports the number of characters
2450 consumed like any other encoder (instead of the number of bytes).
2451
Georg Brandlba83f822010-03-14 09:50:54 +00002452- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2453 allocator will be automatically disabled when running under Valgrind. This
2454 gives improved memory leak detection when running under Valgrind, while taking
2455 advantage of pymalloc at other times.

3686 __all__ attribute, rather than using a hardcoded and incomplete list.
3687
R. David Murray14dcd432009-10-14 13:58:07 +00003688- Issue #7058: Added save/restore for things like sys.argv and cwd to
3689 runtest_inner in regrtest, with warnings if the called test modifies them,
3690 and a new section in the summary report at the end.

Brett Cannone7e941e2009-09-03 21:25:21 +00003694- Issue #6806: test_platform failed under OS X 10.6.0 because ``sw_ver`` leaves
3695 off the trailing 0 in the version number.
3696
Guilherme Polo7f146ab2009-06-21 17:22:50 +00003697- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3698 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003699 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3700 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00003702- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3703 regression tests in parallel, shortening the total runtime.
3704
Georg Brandlba83f822010-03-14 09:50:54 +00003705- Issue #5354: New test support function import_fresh_module() makes it easy to
3706 import both normal and optimised versions of modules. test_heapq and
3707 test_warnings have been adjusted to use it, tests for other modules with both
3708 C and Python implementations in the stdlib can be adjusted to use it over
3709 time.

3716
Georg Brandlba83f822010-03-14 09:50:54 +00003717- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3718 should cause a test to be skipped are now done using import_module from test
3719 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003820- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3821
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003822- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3823 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3824 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3825 ``printf`` function, whereas PyString_FromFormat has an independent
3826 implementation and uses "%zd" on all platforms for size_t values.
3827 This makes a difference on win64, where ``printf`` needs "%Id" to display
3828 64bit values.
3829
Benjamin Peterson97179b02008-09-09 20:55:01 +00003830- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3834 object; previously an int would be returned for small values. the __long__
3835 method is allowed to return either an int or a long, but the behaviour of
3836 float objects should not change to respect backward compatibility.
3837
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003838- Issue #3751: str.rpartition would perform a left-partition when called with
3839 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003844 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003845 was correctly parsed but parsing of subsequent arguments failed.
3846
Vinay Sajip35e3b032008-09-01 14:33:59 +00003847- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003848 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3849 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3850 when given a tuple of classes as second argument, were looking up
3851 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3852 type object.
3853
Neal Norwitz18aa3882008-08-24 05:04:52 +00003854- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003991What's New in Python 2.6 beta 3?
3992================================
3993
Barry Warsaw07a4a382008-08-21 01:15:08 +00003994*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003995
3996Core and Builtins
3997-----------------
3998
Guido van Rossumf8402962008-08-20 15:01:50 +00003999- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4000 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4001 extensions do not automatically benefit from the class attribute
4002 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4003 to their tp_flags field if they care. This is a backwards
4004 compatibility feature; in 3.0, all types will use the cache by
4005 default.
4006
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004007- Keyword arguments can now follow starred arguments. (``f(a, *args,
4008 keyword=23)`` is now valid syntax.)
4009
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004010- ctypes function pointers that are COM methods have a boolean True
4011 value again.
4012
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004013- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4014 by denying s# to parse objects that have a releasebuffer procedure,
4015 and introducing s*.
4016
Georg Brandl1e13ea92008-08-11 09:07:59 +00004017- Issue #3537: Fix an assertion failure when an empty but presized dict
4018 object was stored in the freelist.
4019
Mark Dickinsonb6467572008-08-04 21:30:09 +00004020- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4021 ValueError consistently across platforms.
4022
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004023- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4024 (64bit Unix, for example), unichr() would truncate its argument and return
4025 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4026
Neal Norwitze7d8be82008-07-31 17:17:14 +00004027- Apply security patches from Apple.
4028
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004029- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4030 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4031
Antoine Pitrou92f82162008-07-25 22:22:08 +00004032- Issue #1819: function calls with several named parameters are now on
4033 average 35% faster (as measured by pybench).
4034
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004035- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4036 the python debugger steps into a class statement: the free variables (local
4037 variables defined in an outer scope) would be deleted from the outer scope.
4038
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004039- Issue #2620: Overflow checking when allocating or reallocating memory
4040 was not always being done properly in some python types and extension
4041 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4042 all been updated to perform better checks and places in the code that
4043 would previously leak memory on the error path when such an allocation
4044 failed have been fixed.

4048
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004049- Issue #3612: Added some missing basic types in ctypes.wintypes.
4050
Benjamin Petersone977ad42008-08-20 01:42:01 +00004051- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4052 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4053
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004054- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4055 version reported by these tools does not necessarily follow the python
4056 version numbering scheme, so the module is less strict when parsing it.
4057
Nick Coghlanf70385a2008-08-18 12:42:46 +00004058- Issue #2235: Added Py3k warnings for types which will become unhashable
4059 under the stricter __hash__ inheritance rules in 3.0. Several types
4060 which did not meet the rules for hash invariants and were already
4061 unhashable in 3.0 have now been explicitly flagged as unhashable in
4062 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4063 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4064
Brett Cannon88f801d2008-08-18 00:46:22 +00004065- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4066 imported into the module but exposed as part of the module's API.
4067
Brett Cannon7b96f072008-08-18 00:41:11 +00004068- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4069
Brett Cannon46225e72008-08-18 00:36:52 +00004070- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4071
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004072- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4073
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004074- Issue #3575: Incremental decoder's decode function now takes bytearray
4075 by using 's*' instead of 't#'.
4076
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004077- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004078 fails unicode conversion on 2nd parameter. (windows only)
4079
Georg Brandl222e2082010-08-01 22:27:39 +00004080- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004081 in a redirect.
4082
Brett Cannonabe423e2008-08-16 21:47:07 +00004083- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004084 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004085
Facundo Batistaeb90b782008-08-16 14:44:07 +00004086- Issue #2776: fixed small issue when handling an URL with double slash
4087 after a 302 response in the case of not going through a proxy.
4088
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004089- Issue #2676: in the email package, content-type parsing was hanging on
4090 pathological input because of quadratic or exponential behaviour of a
4091 regular expression.
4092
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004093- Issue #3476: binary buffered reading through the new "io" library is now
4094 thread-safe.
4095
Brett Cannonbf3157b2008-08-14 05:00:03 +00004096- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4097 since mimetools itself is deprecated. Because modules are cached, all
4098 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4099
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004100- Issue #3134: shutil referenced undefined WindowsError symbol.
4101
Robert Schuppenies14646332008-08-10 11:01:53 +00004102- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4103 menu entries were not deleted.
4104
Brett Cannon83e81842008-08-09 23:30:55 +00004105- Copied the implementation of reduce() to _functools.reduce() to have a
4106 version that did not raise a DeprecationWarning under -3.
4107
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004108- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4109 a MemoryError rather than silently stop the iteration.
4110
Guido van Rossum59ce9012008-08-09 14:55:34 +00004111- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4112 to _sre.compile() will now be rejected. This should not affect anybody
4113 since the re.compile() function never generates invalid re-bytecode.
4114
Skip Montanaroa032bf42008-08-08 22:52:51 +00004115- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4116 upon first access it can be automatically initialized from the csv file if
4117 it wasn't initialized during instantiation.
4118
Brett Cannon3aa2a492008-08-06 22:28:09 +00004119- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4120 the reload() built-in has been removed.
4121
Brett Cannon7e30b672008-08-04 21:52:25 +00004122- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004123 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Brett Cannon7e30b672008-08-04 21:52:25 +00004129
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004130- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4131 raised an AttributeError.
4132
Benjamin Peterson01a24322008-07-28 23:35:27 +00004133- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004134 asking for a specific length. This problem only affected files opened
4135 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004136
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004137- Issue #3449: Update decimal module to use most recent specification
4138 (v. 1.68) and tests (v. 2.58) from IBM.
4139
Georg Brandl222e2082010-08-01 22:27:39 +00004140- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004141

4144
Georg Brandlf9efabb2008-07-23 15:16:45 +00004145- Deprecate the "ast" parser function aliases.
4146
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004147- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4148
4149- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4150 invalid arguments.
4151
4152- Issue #3302: Fix several crashes when calling locale's gettext functions
4153 with None arguments.
4154
4155- Issue #3389: Allow resolving dotted names for handlers in logging
4156 configuration files.
4157
4158- Deprecate the sunaudio module for removal in Python 3.0.
4159
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004160- Issue #3394: zipfile.writestr sets external attributes when passed a
4161 file name rather than a ZipInfo instance, so files are extracted with
4162 mode 0600 rather than 000 under Unix.
4163
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004164- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4165 argument in python 2.5, this broke code that subclassed Popen to include its
4166 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004176- Issue #2235: the C API function PyObject_HashNotImplemented and its
4177 interaction with the tp_hash slot (added in 2.6b2) are now documented
4178
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004179- Issue #643841: The language reference now provides more detailed
4180 coverage of the lookup process for special methods. The disclaimers
4181 regarding lack of coverage of new-style classes have also been
4182 removed, since the coverage is now fairly reasonable.

4191-----------------
4192
Georg Brandl3e483f62008-07-16 22:57:41 +00004193- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4194 its methods now allow for items objects that can be converted to
4195 an integer using operator.index().
4196
Mark Dickinson64b7e502008-07-16 09:40:03 +00004197- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4198 produced a ValueError instead of giving the correct float.
4199
Eric Smitha5fa5a22008-07-16 00:11:49 +00004200- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4201 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4202
Mark Dickinson7103aa42008-07-15 19:08:33 +00004203- Issue #3008: the float type has a new instance method 'float.hex'
4204 and a new class method 'float.fromhex' to convert floating-point
4205 numbers to and from hexadecimal strings, respectively.
4206
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004207- Issue #2235: __hash__ is once again inherited by default. To allow
4208 collections.Hashable to remain meaningful in the presence of the
4209 default hash implementation (object.__hash__), it is now possible
4210 to explicit block inheritance of hash by setting __hash__=None at
4211 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4212 level.
4213
Nick Coghlanb028f502008-07-13 14:52:36 +00004214- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4215 the parent module cannot be found while performing an absolute import.
4216 This means that an incorrectly defined __package__ attribute will
4217 now only prevent relative imports in that module rather than causing
4218 all imports from that module to fail.
4219
Nick Coghlan14ff9942008-07-08 14:21:42 +00004220- Issue #2517: Allow unicode messages in Exceptions again by correctly
4221 bypassing the instance dictionary when looking up __unicode__ on
4222 new-style classes.
4223
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004224- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4225 set to a custom object whose write() method happens to install
4226 another file in sys.stdout.

4230 another thread's dictionary.
4231
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004232- Issue #3004: Minor change to slice.indices(): the start and stop
4233 arguments are now treated identically, making the behaviour easier
4234 to describe and understand. For example, slice(None, -10,
4235 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4236 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4237 10, -1).
4238
Georg Brandl278fc502008-07-19 12:46:12 +00004239- Issue #3219: Calling a function with repeated keyword arguments,
4240 f(a=2, a=23), would not cause a syntax error. This was a regression
4241 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00004691 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004692
4693 This is controlled by the configure argument ``--with-universal-archs``:
4694
4695 - ``--with-universal-archs=all``: install 4-way universal
4696
4697 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4698
4699 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4700

Georg Brandl3ee81df2008-05-17 18:14:43 +00004753- Issue #1631171: Re-implement the 'warnings' module in C (the
4754 original Python code has been kept as backup). This will allow for
4755 using the 'warning's machinery in such places as the parser where
4756 use of pure Python code is not possible. Both the ``showarning()``
4757 and ``formatwarning()`` gain an optional 'line' argument which is
4758 not called by default for backwards-compatibility reasons. Setting
4759 ``warnings.showwarning()`` to an implementation that lacks support
4760 for the ``line`` argument will raise a DeprecationWarning.

4784
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004785- The getpass module has been improved on Unix. It now uses /dev/tty
4786 by default and uses stderr instead of stdout. A GetPassWarning is
4787 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004802- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004803 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004815- Issue #2385: distutils.core.run_script() makes __file__ available,
4816 so the controlled environment will more closely mirror the typical
4817 script environment. This supports setup.py scripts that refer to
4818 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004823- Issue #2550: The approach used by client/server code for obtaining
4824 ports to listen on in network-oriented tests has been refined in an
4825 effort to facilitate running multiple instances of the entire
4826 regression test suite in parallel without issue.
4827 test_support.bind_port() has been fixed such that it will always
4828 return a unique port -- which wasn't always the case with the
4829 previous implementation, especially if socket options had been set
4830 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4831 new implementation of bind_port() will actually raise an exception
4832 if it is passed an AF_INET/SOCK_STREAM socket with either the
4833 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4834 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4835 the socket it's been passed. This currently only applies to
4836 Windows. This option prevents any other sockets from binding to the
4837 host/port we've bound to, thus removing the possibility of the
4838 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4839 when a second SOCK_STREAM socket binds and accepts to a host/port
4840 that's already been bound by another socket. The optional preferred
4841 port parameter to bind_port() has been removed. Under no
4842 circumstances should tests be hard coding ports!
4843
4844 test_support.find_unused_port() has also been introduced, which will
4845 pass a temporary socket object to bind_port() in order to obtain an
4846 unused port. The temporary socket object is then closed and
4847 deleted, and the port is returned. This method should only be used
4848 for obtaining an unused port in order to pass to an external program
4849 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4850 a parameter to a server-oriented class that doesn't give you direct
4851 access to the underlying socket used.
4852
4853 Finally, test_support.HOST has been introduced, which should be used
4854 for the host argument of any relevant socket calls (i.e. bind and
4855 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004856
4857 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004858 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004859 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4860 test_asynchat and test_socket_ssl.
4861
Georg Brandl3ee81df2008-05-17 18:14:43 +00004862 It is now possible for multiple instances of the regression test
4863 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00005132- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005133 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00005142- Added the future_builtins module, which contains hex() and oct().
5143 These are the PEP 3127 version of these functions, designed to be
5144 compatible with the hex() and oct() builtins from Python 3.0. They
5145 differ slightly in their output formats from the existing, unchanged
5146 Python 2.6 builtins. The expected usage of the future_builtins
5147 module is:
5148 from future_builtins import hex, oct
5149
Eric Smith7ef40bf2008-02-20 23:34:22 +00005150- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5151 exponents for exponents with absolute value < 100. Follows C99
5152 standard. This is a change on Windows, which would use 3 digits.
5153 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5154 so that any alterations it does to the resulting string will be
5155 available in stringlib/formatter.h (for float.__format__).
5156
Eric Smith5a3c1352008-02-19 13:21:56 +00005157- Implemented PEP 3101, Advanced String Formatting. This adds a new
5158 builtin format(); a format() method for str and unicode; a
5159 __format__() method to object, str, unicode, int, long, float, and
5160 datetime; the class string.Formatter; and the C API
5161 PyObject_Format().
5162
Georg Brandl3ee81df2008-05-17 18:14:43 +00005163- Fixed several potential crashes, all caused by specially crafted
5164 __del__ methods exploiting objects in temporarily inconsistent
5165 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005166
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005167- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005168 prevent a possible crash: an Abstract Base Class would try to access
5169 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005170

Georg Brandl3ee81df2008-05-17 18:14:43 +00005174- Clear all free lists during a gc.collect() of the highest generation
5175 in order to allow pymalloc to free more arenas. Python may give back
5176 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005177
Georg Brandl3ee81df2008-05-17 18:14:43 +00005178- Issue #2045: Fix an infinite recursion triggered when printing a
5179 subclass of collections.defaultdict, if its default_factory is set
5180 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005181
Christian Heimesf75dbef2008-02-08 00:11:31 +00005182- Fixed a minor memory leak in dictobject.c. The content of the free
5183 list was not freed on interpreter shutdown.
5184
Georg Brandl21e99f42010-03-07 15:23:59 +00005185- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005186 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005187
Georg Brandl3ee81df2008-05-17 18:14:43 +00005188- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5189 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005190 to compact the internal free lists of pre-allocted ints and floats.
5191
Georg Brandl3ee81df2008-05-17 18:14:43 +00005192- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5193 calls. Python expected the return type int but the fork familie
5194 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005195
Georg Brandl3ee81df2008-05-17 18:14:43 +00005196- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5197 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005208- Patch #1473257: generator objects gain a gi_code attribute. This is
5209 the same object as the func_code attribute of the function that
5210 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005211
Georg Brandl3ee81df2008-05-17 18:14:43 +00005212- Issue #1920: "while 0" statements were completely removed by the
5213 compiler, even in the presence of an "else" clause, which is
5214 supposed to be run when the condition is false. Now the compiler
5215 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005216
Guido van Rossumeead05f2008-01-24 18:21:02 +00005217- A few crashers fixed: weakref_in_del.py (issue #1377858);
5218 loosing_dict_ref.py (issue #1303614, test67.py);
5219 borrowed_ref_[34].py (not in tracker).
5220
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005221- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005222 suppressed while an extension is loaded by calling SetErrorMode in
5223 dynload_win.c. The error is still reported properly.
5224
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005226 several extension methods and modules do not work without unicode
5227 support.
5228
Georg Brandl26543b12008-01-21 18:36:51 +00005229- Issue #1882: when compiling code from a string, encoding cookies in the
5230 second line of code were not always recognized correctly.
5231
Georg Brandl14404b62008-01-19 19:27:05 +00005232- Issue #1679: "0x" was taken as a valid integer literal.
5233
Georg Brandl6caad7d2008-01-26 14:19:22 +00005234- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005235 added.
5236
Christian Heimesc94e2b52008-01-14 04:13:37 +00005237- sys.float_info / PyFloat_GetInfo: The floating point information
5238 object was converted from a dict to a specialized structseq object.
5239
Georg Brandl3ee81df2008-05-17 18:14:43 +00005240- Patch #1816: Added sys.flags structseq. It exposes the status of
5241 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005242
Georg Brandl3ee81df2008-05-17 18:14:43 +00005243- Objects/structseq.c: Implemented new structseq representation. The
5244 patch makes structseqs (e.g. the return value of os.stat) more
5245 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005246
Georg Brandl3ee81df2008-05-17 18:14:43 +00005247- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00005259- Improve some exception messages when Windows fails to load an
5260 extension module. Now we get for example '%1 is not a valid Win32

Georg Brandl3ee81df2008-05-17 18:14:43 +00005269 and INF. float("nan"), float("inf") and float("-inf") now work on
5270 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005271
Georg Brandl3ee81df2008-05-17 18:14:43 +00005272- Compiler now generates simpler and faster code for dictionary
5273 literals. The oparg for BUILD_MAP now indicates an estimated
5274 dictionary size. There is a new opcode, STORE_MAP, for adding
5275 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00005319- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005320 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5321 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005322
Georg Brandl3ee81df2008-05-17 18:14:43 +00005323- Issue #1686386: Tuple's tp_repr did not take into account the
5324 possibility of having a self-referential tuple, which is possible
5325 from C code. Nor did object's tp_str consider that a type's tp_str
5326 could do something that could lead to an inifinite recursion.
5327 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5328 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005329
Georg Brandl3ee81df2008-05-17 18:14:43 +00005330- Issue #1164: It was possible to trigger deadlock when using the
5331 'print' statement to write to a file since the GIL was not released
5332 as needed. Now PyObject_Print() does the right thing along with
5333 various tp_print implementations of the built-in types and those in
5334 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005335
Georg Brandl3ee81df2008-05-17 18:14:43 +00005336- Issue #1147: Exceptions were directly allowing string exceptions in
5337 their throw() method even though string exceptions no longer
5338 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005339
Georg Brandl3ee81df2008-05-17 18:14:43 +00005340- Issue #1096: Prevent a segfault from getting the repr of a very
5341 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005342
Brett Cannon1e534b52007-09-07 04:18:30 +00005343- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005344 PyObject_Call() never calling back out to Python code to trigger
5345 recursion depth updates/checks. Required the creation of a static
5346 RuntimeError instance in case normalizing an exception put the
5347 recursion check value past its limit. Fixes crashers
5348 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005349

Neal Norwitz0ac60192007-05-27 04:08:54 +00005363- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005364 __*__ attributes. (Some already existed, e.g., __doc__ and
5365 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005366
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005367- Add -3 option to the interpreter to warn about features that are
5368 deprecated and will be changed/removed in Python 3.0.
5369
Georg Brandl2134e752007-05-21 20:34:16 +00005370- Patch #1686487: you can now pass any mapping after '**' in function
5371 calls.
5372
Collin Winter62903052007-05-18 23:11:24 +00005373- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005374 "except E as target:". This is to provide forwards compatibility
5375 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005382- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005383 setting a plain string, ie don't expand to single letter identifiers.
5384
Raymond Hettinger13936692007-04-11 18:40:58 +00005385- Request #1191699: Slices can now be pickled.
5386
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005387- Request #1193128: str.translate() now allows a None argument for
5388 translations that only remove characters without re-mapping the
5389 remaining characters.
5390
Georg Brandl5cb76c12007-03-21 09:00:39 +00005391- Patch #1682205: a TypeError while unpacking an iterable is no longer

5395
Guido van Rossum143b5642007-03-23 04:58:42 +00005396- Bug #1683368: The object.__init__() and object.__new__() methods are
5397 now stricter in rejecting excess arguments. The only time when
5398 either allows excess arguments is when it is not overridden and the
5399 other one is. For backwards compatibility, when both are
5400 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005401 warning later). Also, type.__init__() insists on the same signature
5402 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005403
Georg Brandl3ee81df2008-05-17 18:14:43 +00005404- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5405 object to complex using its __complex__() method before falling back
5406 to the __float__() method. Therefore, the functions in the cmath
5407 module now can operate on objects that define a __complex__()
5408 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005409
Georg Brandl3ee81df2008-05-17 18:14:43 +00005410- Patch #1623563: allow __class__ assignment for classes with

5419 its type.

5425
Georg Brandl7b9c5552007-03-12 14:30:05 +00005426- Bug #1678647: write a newline after printing an exception in any
5427 case, even when converting the value to a string failed.
5428
Georg Brandl871f1bc2007-03-12 13:17:36 +00005429- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005430 its argument, if it exists. If not, it will work like before. This
5431 allows customizing the output of dir() in the presence of a
5432 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005440- Patch #1491866: change the complex() constructor to allow
5441 parthensized forms. This means complex(repr(x)) now works instead of
5442 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005443
Georg Brandlaa2321b2007-03-07 00:40:28 +00005444- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005445 makes the filenames the warning module prints much more sensible
5446 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005447

Georg Brandl0fca97a2007-03-05 22:28:08 +00005459- Patch #1674228: when assigning a slice (old-style), check for the
5460 sq_ass_slice instead of the sq_slice slot.
5461
Georg Brandl3ee81df2008-05-17 18:14:43 +00005462- When printing an unraisable error, don't print exceptions. before
5463 the name. This duplicates the behavior whening normally printing
5464 exceptions.

6093 exception.

6306 partial fix for Bug #1574584.
6307
Georg Brandl3ee81df2008-05-17 18:14:43 +00006308- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006374- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6375 with RFC 3207 and forgets any knowledge obtained from the server not
6376 obtained from the TLS negotiation itself. Patch contributed by Bill
6377 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006378
Georg Brandl3ee81df2008-05-17 18:14:43 +00006379- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006380 that the SMTP.starttls() caller no longer needs to call ehlo()
6381 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006382 does not claim to support starttls. Adds the
6383 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6384 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006438- itertools.chain() now has an alternate constructor,

6453 contents before adding elements from the iterable. This fix brings
6454 the behavior into line with that for list.__init__().

6464 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6465 silently miscode subclasses of those types. Now, it raises a
6466 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006467

Georg Brandl3ee81df2008-05-17 18:14:43 +00006482 time so that opening a database previously created with the DB_DUP
6483 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6484 opens. Specifically: dictionary assignment to a DB object will
6485 replace all values for a given key when the database allows
6486 duplicate values. DB users should use DB.put(k, v) when they want
6487 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006488

6494 characters with ASCII value less than 32. Also, it correctly quotes
6495 dots only if they occur on a single line, as opposed to the previous
6496 behavior of quoting dots if they are the second character of any
6497 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006498

6820-----
6821
Georg Brandl3ee81df2008-05-17 18:14:43 +00006822- Unified naming convention for free lists and their limits. All free
6823 lists in Object/ are named ``free_list``, the counter ``numfree``
6824 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6825 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006826
Georg Brandl3ee81df2008-05-17 18:14:43 +00006827- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6828 to ``PyTuple_SetItem``, it can be used to populate a brand new
6829 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006830
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006831- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

6834 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6835 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006836
6837- Patch #1720595: add T_BOOL to the range of structmember types.
6838
6839- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6840 ``PyFloat_GetInfo()`` to the float API.
6841
Georg Brandl3ee81df2008-05-17 18:14:43 +00006842- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6843 of w# format code incorrectly truncated the length to an int, even
6844 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6845 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006846
Georg Brandl3ee81df2008-05-17 18:14:43 +00006847- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6848 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006849
Georg Brandl3ee81df2008-05-17 18:14:43 +00006850- PEP 3123: Provide forward compatibility with Python 3.0, while
6851 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6852 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006853
Georg Brandl3ee81df2008-05-17 18:14:43 +00006854- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6855 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006856
6857- Patch #1733960: Allow T_LONGLONG to accept ints.

6864
6865- Fix some leftovers from the conversion from int to Py_ssize_t
6866 (relevant to strings and sequences of more than 2**31 items).
6867
6868- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6869 outside of pystate.c and should not be necessary.
6870
Georg Brandl3ee81df2008-05-17 18:14:43 +00006871- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6872 absolute imports. In earlier versions they might have used relative
6873 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006874
Georg Brandl3ee81df2008-05-17 18:14:43 +00006875- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6876 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006877
Georg Brandl3ee81df2008-05-17 18:14:43 +00006878- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6879 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006885- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6886 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6887 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6888 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006889

Georg Brandl3ee81df2008-05-17 18:14:43 +00006903- Removed the macfs module. It had been deprecated since Python 2.5.
6904 This lead to the deprecation of macostools.touched() as it relied
6905 solely on macfs and was a no-op under OS X.
