348 thread-local storage key.
349
Victor Stinnercaafd772010-09-08 10:51:01 +0000350- Issue #4947: The write() method of sys.stdout and sys.stderr uses their

352 the same behaviour than the print statement.
353
Antoine Pitrou9cf85f12010-09-01 21:17:34 +0000354- Issue #9737: Fix a crash when trying to delete a slice or an item from

477
Antoine Pitrou6391b342010-09-14 18:48:19 +0000478- Issue #9854: The default read() implementation in io.RawIOBase now
479 handles non-blocking readinto() returning None correctly.
480

482 SSLSocket.sendto() to match the corresponding socket methods. Also,
483 fix various SSLSocket methods to raise socket.error rather than an
484 unhelpful TypeError when called on an unconnected socket. Original patch
485 by Andrew Bennetts.
486
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000487- Issue #9826: OrderedDict.__repr__ can now handle self-referential
488 values: d['x'] = d.

494
Raymond Hettinger20397532010-09-12 02:11:45 +0000495- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
496 This prevents user-created self-referencing ordered dictionaries from
497 becoming permanently uncollectable GC garbage. The downside is that
498 removing __del__ means that the internal doubly-linked list has to wait for
499 GC collection rather than freeing memory immediately when the refcnt drops
500 to zero.
501
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000502- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000503 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000504 value.
505
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000506- Issue #9792: In case of connection failure, socket.create_connection()
507 would swallow the exception and raise a new one, making it impossible
508 to fetch the original errno, or to filter timeout errors. Now the
509 original error is re-raised.
510
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000511- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
512 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
513 be updated back after the system call. Original patch by Brian Brazil.
514
Antoine Pitroudca9de92010-09-04 17:52:26 +0000515- Issue #1100562: Fix deep-copying of objects derived from the list and
516 dict types. Patch by Michele Orrù and Björn Lindqvist.
517
Fred Drakea1e627d2010-09-03 03:55:50 +0000518- Issue #7005: Fixed output of None values for RawConfigParser.write and
519 ConfigParser.write.
520
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000521- Issue #808164: Fixed socket.close to avoid references to globals, to
522 avoid issues when socket.close is called from a __del__ method.
523
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000524- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
525 can be set to False to turn off the previously undocumented 'popularity'
526 heuristic. Patch by Terry Reedy and Eli Bendersky
527
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000528- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
529 falling into recursion.
530
R. David Murray7c4bf552010-08-25 01:45:57 +0000531- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
532 character years even if the message contains RFC822 two character years.
533
Daniel Stutzbach91287322010-08-24 21:09:30 +0000534- Issue #8750: Fixed MutableSet's methods to correctly handle
535 reflexive operations, namely x -= x and x ^= x.
536
Victor Stinnercaafd772010-09-08 10:51:01 +0000537- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

541 errors.

546 module now correctly return a set. (Patch by Eli Bendersky.)
547
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000548- Issue #9617: Signals received during a low-level write operation aren't
549 ignored by the buffered IO layer anymore.
550
Benjamin Peterson52c36052010-08-21 03:03:22 +0000551- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
552 are not held onto after they are deleted elsewhere.
553
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000554- Issue #9626: the view methods for collections.OrderedDict() were returning
555 the unordered versions inherited from dict. Those methods are now
556 overridden to provide ordered views.
557
Éric Araujo0389ae62010-08-14 03:07:46 +0000558- Issue #8688: MANIFEST files created by distutils now include a magic
559 comment indicating they are generated. Manually maintained MANIFESTs
560 without this marker will not be overwritten or removed.
561
Antoine Pitroue1436d12010-08-12 15:25:51 +0000562- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

564 case in Python 2.5 and earlier).
565
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000566- Issue #9550: a BufferedReader could issue an additional read when the
567 original read request had been satisfied, which could block indefinitely
568 when the underlying raw IO channel was e.g. a socket. Report and original
569 patch by Jason V. Miller.
570
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000571- Issue #9551: Don't raise TypeError when setting the value to None for
572 SafeConfigParser instances constructed with allow_no_value == True.
573
Antoine Pitrou8cdede42010-08-10 00:04:13 +0000574- Issue #6915: Under Windows, os.listdir() didn't release the Global

590 This is how it is supposed to work, wget and curl do the same. Previous
591 behavior was wrong.
592

599 the option character for the added 'h/help' option if prefix_chars
600 does not contain a '-', instead of raising an error.

957
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000958- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
959 start byte and the continuation byte(s) are now considered invalid, instead
960 of the number of bytes specified by the start byte.
961 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
962 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
963 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
964 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000966- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000967 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
968 arises from the "Overriding __eq__ blocks inheritance ..." warning
969 when turned into an exception: in this case the exception simply
970 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000972- Issue #8748: Fix two issues with comparisons between complex and integer
973 objects. (1) The comparison could incorrectly return True in some cases
974 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
975 (2) The comparison raised an OverflowError for large integers, leading
976 to unpredictable exceptions when combining integers and complex objects
977 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +0000979- Issue #5211: Implicit coercion for the complex type is now completely
980 removed. (Coercion for arithmetic operations was already removed in 2.7
981 alpha 4, but coercion for rich comparisons was accidentally left in.)
982
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000983- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

1347 changed.

1360 with a non-empty format string. This is an effort to future-proof user
1361 code. If a derived class does not currently implement __format__ but later
1362 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001363 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001364 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitroud840e512010-02-04 20:20:18 +00001849- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001850 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00001857 file position when calling `truncate()`. It would previously change the file
1858 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001859 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1860

1862 class used to represent files stored inside an archive. The new
1863 implementation is significantly faster and can be wrapped in a
1864 ``io.BufferedReader`` object for more speedups. It also solves an issue
1865 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001876- Issue #7748: Since unicode values are supported for some metadata options in

1878 encoded string for them. This ensures that the upload and register commands
1879 send the correct values to PyPI without any error.

1955
Georg Brandlba83f822010-03-14 09:50:54 +00001956- The ``__complex__()`` method is now looked up on the class of instances to
1957 make it consistent with other special methods.

1961
Mark Dickinson1b34d252010-01-01 17:27:30 +00001962- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001963 DeprecationWarning when passed a float argument where an integer was expected.
1964 These functions and methods now raise TypeError instead. The majority of the
1965 effects of this change are in the extension modules, but some core functions
1966 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1967 and many unicode/str methods.

1981 of integers: the result of a/b is now correctly rounded for ints a and b (at
1982 least on IEEE 754 platforms), and in particular does not depend on the
1983 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001992 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002132- Issue #3382: 'F' formatting for float and complex now convert the result to
2133 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2134 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002135
Georg Brandlba83f822010-03-14 09:50:54 +00002136- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2137 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002138
Georg Brandlba83f822010-03-14 09:50:54 +00002139- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2140 1e-100 used to raise OverflowError, but now gives the requested 120
2141 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00002142

2148 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002149
Georg Brandlba83f822010-03-14 09:50:54 +00002150- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2151 decimal string that's guaranteed to round back to x under correct rounding
2152 (with round-half-to-even rounding mode). Previously it gave a string based on
2153 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2154 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2155 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002156
Georg Brandlba83f822010-03-14 09:50:54 +00002157- Issue #7117: On almost all platforms: float-to-string and string-to-float
2158 conversions within Python are now correctly rounded. Places these conversions
2159 occur include: str for floats and complex numbers; the float and complex
2160 constructors; old-style and new-style numeric formatting; serialization and
2161 deserialization of floats and complex numbers using marshal, pickle and json;
2162 parsing of float and imaginary literals in Python code; Decimal-to-float
2163 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002164
Georg Brandlba83f822010-03-14 09:50:54 +00002165 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2166 providing correctly-rounded strtod and dtoa C functions. This code is
2167 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2168 the C compiler. There may be a small number of platforms on which correct
2169 operation of this code cannot be guaranteed, so the code is not used: notably,
2170 this applies to platforms where the C double format is not IEEE 754 binary64,
2171 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2172 and Python's configure script is unable to determine how to change the FPU
2173 precision. On these platforms conversions use the platform strtod and dtoa,
2174 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002176- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2177 uses the correctly-rounded string <-> float conversions described above (when
2178 available), and so produces correctly rounded results that will display nicely
2179 under the float repr. There are two related small changes: (1) round now
2180 accepts any class with an ``__index__()`` method for its second argument (but
2181 no longer accepts floats for the second argument), and (2) an excessively
2182 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2183 raises an exception.

2186
Georg Brandlba83f822010-03-14 09:50:54 +00002187- Fix several issues with ``compile()``. The input can now contain Windows and
2188 Mac newlines and is no longer required to end in a newline.

2332 but with at least one decimal point and with a default precision
2333 of 12. Previously, the behavior the same but with a default precision of 6.
2334 This more closely matches ``str()``, and reduces surprises when adding

3753 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
3754 consistently raises struct.error.
Mark Dickinson5fd3af22009-07-07 15:08:28 +00003755
Georg Brandlba83f822010-03-14 09:50:54 +00003756- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the

Georg Brandlba83f822010-03-14 09:50:54 +00003760 - Packing a float now always gives a Deprecation Warning. Previously it
3761 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003762
Georg Brandlba83f822010-03-14 09:50:54 +00003763 - If x is not an int, long or float, then packing x will always result in
3764 struct.error. Previously an x with an __int__ method could be packed by
3765 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3766 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3767 neither __int__ nor __long__, TypeError used to be raised (with a
3768 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3769 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003770
Georg Brandlba83f822010-03-14 09:50:54 +00003771 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
3772 argument with an __int__ method can be packed, but use of this feature
3773 triggers a DeprecationWarning.

3807 in the Lib/test directory, which might be read-only for the user running the
3808 tests.
R. David Murray820b0ea2009-12-03 23:57:59 +00003809
Georg Brandlba83f822010-03-14 09:50:54 +00003810- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
3811 of an option with no handler.
R. David Murrayda826892009-11-15 00:04:32 +00003812
Georg Brandlba83f822010-03-14 09:50:54 +00003813- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
3814 fails. Can be combined with -j.
R. David Murray7f7eea62009-11-14 15:18:22 +00003815
Antoine Pitrou310c9fe2009-11-11 20:55:07 +00003816- Issue #7295: Do not use a hardcoded file name in test_tarfile.

3820
Antoine Pitrou59c44f32009-10-30 17:07:08 +00003821- Issue #7222: Make thread "reaping" more reliable so that reference
Georg Brandlba83f822010-03-14 09:50:54 +00003822 leak-chasing test runs give sensible results. The previous method of reaping
3823 threads could return successfully while some Thread objects were still
3824 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00003825
Georg Brandlba83f822010-03-14 09:50:54 +00003826- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
3827 runs the risk of causing the worker thread to fail.
R. David Murray282396f2009-10-18 21:12:37 +00003828
Antoine Pitrou58d2f262009-10-10 20:52:11 +00003829- Issue #7055: test___all__ now greedily detects all modules which have an
3830 __all__ attribute, rather than using a hardcoded and incomplete list.
3831
R. David Murray14dcd432009-10-14 13:58:07 +00003832- Issue #7058: Added save/restore for things like sys.argv and cwd to
3833 runtest_inner in regrtest, with warnings if the called test modifies them,
3834 and a new section in the summary report at the end.
R. David Murrayabe3d3e2009-10-05 17:03:09 +00003835
Mark Dickinson245d9152009-10-04 18:38:39 +00003836- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.

3839 off the trailing 0 in the version number.
3840
Guilherme Polo7f146ab2009-06-21 17:22:50 +00003841- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3842 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003843 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3844 the tests if DISPLAY is defined but can't be used.
Guilherme Polo7f146ab2009-06-21 17:22:50 +00003845
Antoine Pitrou4698d992009-05-31 14:20:14 +00003846- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3847 regression tests in parallel, shortening the total runtime.
3848
Georg Brandlba83f822010-03-14 09:50:54 +00003849- Issue #5354: New test support function import_fresh_module() makes it easy to
3850 import both normal and optimised versions of modules. test_heapq and
3851 test_warnings have been adjusted to use it, tests for other modules with both
3852 C and Python implementations in the stdlib can be adjusted to use it over
3853 time.

Georg Brandlba83f822010-03-14 09:50:54 +00003861- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3862 should cause a test to be skipped are now done using import_module from test
3863 support, which does the conversion.
R. David Murray41448c52009-03-31 19:57:24 +00003864
Guilherme Polob1a98de2009-01-28 20:03:26 +00003865- Issue #5083: New 'gui' resource for regrtest.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003966- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3967 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3968 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3969 ``printf`` function, whereas PyString_FromFormat has an independent
3970 implementation and uses "%zd" on all platforms for size_t values.
3971 This makes a difference on win64, where ``printf`` needs "%Id" to display
3972 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003987- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003988 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003989 was correctly parsed but parsing of subsequent arguments failed.
3990
Vinay Sajip35e3b032008-09-01 14:33:59 +00003991- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003992 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3993 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3994 when given a tuple of classes as second argument, were looking up
3995 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3996 type object.
3997
Neal Norwitz18aa3882008-08-24 05:04:52 +00003998- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004067 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4068 for catch_warnings() also led to an improvement in the raising of a
4069 DeprecationWarning related to warnings.warn_explicit().
4070

4096 without limit.
4097
Benjamin Peterson37346b22008-08-23 20:27:43 +00004098- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004135What's New in Python 2.6 beta 3?
4136================================
4137
Barry Warsaw07a4a382008-08-21 01:15:08 +00004138*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004139
4140Core and Builtins
4141-----------------
4142
Guido van Rossumf8402962008-08-20 15:01:50 +00004143- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4144 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4145 extensions do not automatically benefit from the class attribute
4146 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4147 to their tp_flags field if they care. This is a backwards
4148 compatibility feature; in 3.0, all types will use the cache by
4149 default.
4150
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004151- Keyword arguments can now follow starred arguments. (``f(a, *args,
4152 keyword=23)`` is now valid syntax.)
4153
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004154- ctypes function pointers that are COM methods have a boolean True
4155 value again.
4156
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004157- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4158 by denying s# to parse objects that have a releasebuffer procedure,
4159 and introducing s*.
4160
Georg Brandl1e13ea92008-08-11 09:07:59 +00004161- Issue #3537: Fix an assertion failure when an empty but presized dict
4162 object was stored in the freelist.
4163
Mark Dickinsonb6467572008-08-04 21:30:09 +00004164- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4165 ValueError consistently across platforms.
4166
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004167- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4168 (64bit Unix, for example), unichr() would truncate its argument and return
4169 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4170
Neal Norwitze7d8be82008-07-31 17:17:14 +00004171- Apply security patches from Apple.
4172
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004173- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4174 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4175
Antoine Pitrou92f82162008-07-25 22:22:08 +00004176- Issue #1819: function calls with several named parameters are now on
4177 average 35% faster (as measured by pybench).
4178
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004179- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4180 the python debugger steps into a class statement: the free variables (local
4181 variables defined in an outer scope) would be deleted from the outer scope.
4182
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004183- Issue #2620: Overflow checking when allocating or reallocating memory
4184 was not always being done properly in some python types and extension
4185 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4186 all been updated to perform better checks and places in the code that
4187 would previously leak memory on the error path when such an allocation
4188 failed have been fixed.

4191-------
4192
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004193- Issue #3612: Added some missing basic types in ctypes.wintypes.
4194
Benjamin Petersone977ad42008-08-20 01:42:01 +00004195- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4196 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4197
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004198- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4199 version reported by these tools does not necessarily follow the python
4200 version numbering scheme, so the module is less strict when parsing it.
4201
Nick Coghlanf70385a2008-08-18 12:42:46 +00004202- Issue #2235: Added Py3k warnings for types which will become unhashable
4203 under the stricter __hash__ inheritance rules in 3.0. Several types
4204 which did not meet the rules for hash invariants and were already
4205 unhashable in 3.0 have now been explicitly flagged as unhashable in
4206 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4207 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4208
Brett Cannon88f801d2008-08-18 00:46:22 +00004209- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4210 imported into the module but exposed as part of the module's API.
4211
Brett Cannon7b96f072008-08-18 00:41:11 +00004212- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4213
Brett Cannon46225e72008-08-18 00:36:52 +00004214- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004216- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4217
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004218- Issue #3575: Incremental decoder's decode function now takes bytearray
4219 by using 's*' instead of 't#'.
4220
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004221- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004222 fails unicode conversion on 2nd parameter. (windows only)
4223
Georg Brandl222e2082010-08-01 22:27:39 +00004224- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004225 in a redirect.
4226
Brett Cannonabe423e2008-08-16 21:47:07 +00004227- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004228 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004229
Facundo Batistaeb90b782008-08-16 14:44:07 +00004230- Issue #2776: fixed small issue when handling an URL with double slash
4231 after a 302 response in the case of not going through a proxy.
4232
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004233- Issue #2676: in the email package, content-type parsing was hanging on
4234 pathological input because of quadratic or exponential behaviour of a
4235 regular expression.
4236
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004237- Issue #3476: binary buffered reading through the new "io" library is now
4238 thread-safe.
4239
Brett Cannonbf3157b2008-08-14 05:00:03 +00004240- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4241 since mimetools itself is deprecated. Because modules are cached, all
4242 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4243
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004244- Issue #3134: shutil referenced undefined WindowsError symbol.
4245
Robert Schuppenies14646332008-08-10 11:01:53 +00004246- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4247 menu entries were not deleted.
4248
Brett Cannon83e81842008-08-09 23:30:55 +00004249- Copied the implementation of reduce() to _functools.reduce() to have a
4250 version that did not raise a DeprecationWarning under -3.
4251
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004252- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4253 a MemoryError rather than silently stop the iteration.
4254
Guido van Rossum59ce9012008-08-09 14:55:34 +00004255- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4256 to _sre.compile() will now be rejected. This should not affect anybody
4257 since the re.compile() function never generates invalid re-bytecode.
4258
Skip Montanaroa032bf42008-08-08 22:52:51 +00004259- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4260 upon first access it can be automatically initialized from the csv file if
4261 it wasn't initialized during instantiation.
4262
Brett Cannon3aa2a492008-08-06 22:28:09 +00004263- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4264 the reload() built-in has been removed.
4265
Brett Cannon7e30b672008-08-04 21:52:25 +00004266- Changed code in the following modules/packages to remove warnings raised

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004334Core and Builtins
4335-----------------
4336
Georg Brandl3e483f62008-07-16 22:57:41 +00004337- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4338 its methods now allow for items objects that can be converted to
4339 an integer using operator.index().
4340
Mark Dickinson64b7e502008-07-16 09:40:03 +00004341- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4342 produced a ValueError instead of giving the correct float.
4343
Eric Smitha5fa5a22008-07-16 00:11:49 +00004344- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4345 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4346
Mark Dickinson7103aa42008-07-15 19:08:33 +00004347- Issue #3008: the float type has a new instance method 'float.hex'
4348 and a new class method 'float.fromhex' to convert floating-point
4349 numbers to and from hexadecimal strings, respectively.
4350
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004351- Issue #2235: __hash__ is once again inherited by default. To allow
4352 collections.Hashable to remain meaningful in the presence of the
4353 default hash implementation (object.__hash__), it is now possible
4354 to explicit block inheritance of hash by setting __hash__=None at
4355 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4356 level.
4357
Nick Coghlanb028f502008-07-13 14:52:36 +00004358- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4359 the parent module cannot be found while performing an absolute import.
4360 This means that an incorrectly defined __package__ attribute will
4361 now only prevent relative imports in that module rather than causing
4362 all imports from that module to fail.
4363
Nick Coghlan14ff9942008-07-08 14:21:42 +00004364- Issue #2517: Allow unicode messages in Exceptions again by correctly
4365 bypassing the instance dictionary when looking up __unicode__ on
4366 new-style classes.

4369 set to a custom object whose write() method happens to install
4370 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004372- Issue #3088: Corrected a race condition in classes derived from
4373 threading.local: the first member set by a thread could be saved in
4374 another thread's dictionary.
4375
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004376- Issue #3004: Minor change to slice.indices(): the start and stop
4377 arguments are now treated identically, making the behaviour easier
4378 to describe and understand. For example, slice(None, -10,
4379 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4380 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4381 10, -1).
4382
Georg Brandl278fc502008-07-19 12:46:12 +00004383- Issue #3219: Calling a function with repeated keyword arguments,
4384 f(a=2, a=23), would not cause a syntax error. This was a regression
4385 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004423- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4424 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004425 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004426 content-length. The problem had been corrected in the 2.4 branch, but never
4427 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004442- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4443 handling is now the same as that of other special attributes like __name__).
4444
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004445- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004833- On MacOS X it is now possible to install the framework in 64-bit
4834 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004835 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004836
4837 This is controlled by the configure argument ``--with-universal-archs``:
4838
4839 - ``--with-universal-archs=all``: install 4-way universal
4840
4841 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4842
4843 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4844
4845 This option should be used in combination with ``--enable-universalsdk=``.
4846
4847 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

4852
Georg Brandl74a1dea2008-05-28 11:21:39 +00004853- Add ``PyType_Modified()`` as a public API to clear the type cache.
4854
4855- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00004856
4857- The PyString functions have been renamed to PyBytes. A batch of
4858 defines were added so that the linker still sees the original
4859 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004897- Issue #1631171: Re-implement the 'warnings' module in C (the
4898 original Python code has been kept as backup). This will allow for
4899 using the 'warning's machinery in such places as the parser where
4900 use of pure Python code is not possible. Both the ``showarning()``
4901 and ``formatwarning()`` gain an optional 'line' argument which is
4902 not called by default for backwards-compatibility reasons. Setting
4903 ``warnings.showwarning()`` to an implementation that lacks support
4904 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004929- The getpass module has been improved on Unix. It now uses /dev/tty
4930 by default and uses stderr instead of stdout. A GetPassWarning is
4931 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004946- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004947 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004967- Issue #2550: The approach used by client/server code for obtaining
4968 ports to listen on in network-oriented tests has been refined in an
4969 effort to facilitate running multiple instances of the entire
4970 regression test suite in parallel without issue.
4971 test_support.bind_port() has been fixed such that it will always
4972 return a unique port -- which wasn't always the case with the
4973 previous implementation, especially if socket options had been set
4974 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4975 new implementation of bind_port() will actually raise an exception
4976 if it is passed an AF_INET/SOCK_STREAM socket with either the
4977 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4978 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4979 the socket it's been passed. This currently only applies to
4980 Windows. This option prevents any other sockets from binding to the
4981 host/port we've bound to, thus removing the possibility of the
4982 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4983 when a second SOCK_STREAM socket binds and accepts to a host/port
4984 that's already been bound by another socket. The optional preferred
4985 port parameter to bind_port() has been removed. Under no
4986 circumstances should tests be hard coding ports!
4987
4988 test_support.find_unused_port() has also been introduced, which will
4989 pass a temporary socket object to bind_port() in order to obtain an
4990 unused port. The temporary socket object is then closed and
4991 deleted, and the port is returned. This method should only be used
4992 for obtaining an unused port in order to pass to an external program
4993 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4994 a parameter to a server-oriented class that doesn't give you direct
4995 access to the underlying socket used.
4996
4997 Finally, test_support.HOST has been introduced, which should be used
4998 for the host argument of any relevant socket calls (i.e. bind and
4999 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005000
5001 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005002 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005003 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5004 test_asynchat and test_socket_ssl.
5005
Georg Brandl3ee81df2008-05-17 18:14:43 +00005006 It is now possible for multiple instances of the regression test
5007 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005286- Added the future_builtins module, which contains hex() and oct().
5287 These are the PEP 3127 version of these functions, designed to be
5288 compatible with the hex() and oct() builtins from Python 3.0. They
5289 differ slightly in their output formats from the existing, unchanged
5290 Python 2.6 builtins. The expected usage of the future_builtins
5291 module is:
5292 from future_builtins import hex, oct
5293
Eric Smith7ef40bf2008-02-20 23:34:22 +00005294- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5295 exponents for exponents with absolute value < 100. Follows C99
5296 standard. This is a change on Windows, which would use 3 digits.
5297 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5298 so that any alterations it does to the resulting string will be
5299 available in stringlib/formatter.h (for float.__format__).
5300
Eric Smith5a3c1352008-02-19 13:21:56 +00005301- Implemented PEP 3101, Advanced String Formatting. This adds a new
5302 builtin format(); a format() method for str and unicode; a
5303 __format__() method to object, str, unicode, int, long, float, and
5304 datetime; the class string.Formatter; and the C API
5305 PyObject_Format().
5306
Georg Brandl3ee81df2008-05-17 18:14:43 +00005307- Fixed several potential crashes, all caused by specially crafted
5308 __del__ methods exploiting objects in temporarily inconsistent
5309 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005310
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005311- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005312 prevent a possible crash: an Abstract Base Class would try to access
5313 a slot on a registered virtual subclass.

5320 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005321
Georg Brandl3ee81df2008-05-17 18:14:43 +00005322- Issue #2045: Fix an infinite recursion triggered when printing a
5323 subclass of collections.defaultdict, if its default_factory is set
5324 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005325
Christian Heimesf75dbef2008-02-08 00:11:31 +00005326- Fixed a minor memory leak in dictobject.c. The content of the free
5327 list was not freed on interpreter shutdown.
5328
Georg Brandl21e99f42010-03-07 15:23:59 +00005329- Limit free list of method and built-in function objects to 256

5333 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005334 to compact the internal free lists of pre-allocted ints and floats.
5335
Georg Brandl3ee81df2008-05-17 18:14:43 +00005336- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5337 calls. Python expected the return type int but the fork familie
5338 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005349- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5350 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005351
Georg Brandl3ee81df2008-05-17 18:14:43 +00005352- Patch #1473257: generator objects gain a gi_code attribute. This is
5353 the same object as the func_code attribute of the function that
5354 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005355
Georg Brandl3ee81df2008-05-17 18:14:43 +00005356- Issue #1920: "while 0" statements were completely removed by the
5357 compiler, even in the presence of an "else" clause, which is
5358 supposed to be run when the condition is false. Now the compiler
5359 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005360
Guido van Rossumeead05f2008-01-24 18:21:02 +00005361- A few crashers fixed: weakref_in_del.py (issue #1377858);
5362 loosing_dict_ref.py (issue #1303614, test67.py);
5363 borrowed_ref_[34].py (not in tracker).
5364
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005365- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005366 suppressed while an extension is loaded by calling SetErrorMode in
5367 dynload_win.c. The error is still reported properly.
5368
Georg Brandl3ee81df2008-05-17 18:14:43 +00005369- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005370 several extension methods and modules do not work without unicode
5371 support.
5372
Georg Brandl26543b12008-01-21 18:36:51 +00005373- Issue #1882: when compiling code from a string, encoding cookies in the
5374 second line of code were not always recognized correctly.
5375
Georg Brandl14404b62008-01-19 19:27:05 +00005376- Issue #1679: "0x" was taken as a valid integer literal.
5377
Georg Brandl6caad7d2008-01-26 14:19:22 +00005378- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005379 added.
5380
Christian Heimesc94e2b52008-01-14 04:13:37 +00005381- sys.float_info / PyFloat_GetInfo: The floating point information
5382 object was converted from a dict to a specialized structseq object.
5383
Georg Brandl3ee81df2008-05-17 18:14:43 +00005384- Patch #1816: Added sys.flags structseq. It exposes the status of
5385 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005386
Georg Brandl3ee81df2008-05-17 18:14:43 +00005387- Objects/structseq.c: Implemented new structseq representation. The
5388 patch makes structseqs (e.g. the return value of os.stat) more
5389 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005390
Georg Brandl3ee81df2008-05-17 18:14:43 +00005391- Patch #1700288: added a type attribute cache that caches method
5392 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005393
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005394- Bug #1776: __import__() no longer accepts filenames on any platform.
5395 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005396
Georg Brandlaed6c662008-01-07 17:25:53 +00005397- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5398
Georg Brandl3ee81df2008-05-17 18:14:43 +00005399- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5400 envvar and sys.dont_write_bytecode attribute. All these can be set
5401 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005402
Georg Brandl3ee81df2008-05-17 18:14:43 +00005403- Improve some exception messages when Windows fails to load an
5404 extension module. Now we get for example '%1 is not a valid Win32
5405 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005406
Georg Brandl3ee81df2008-05-17 18:14:43 +00005407- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005409- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5410 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005411
Christian Heimes0a8143f2007-12-18 23:22:54 +00005412- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005413 and INF. float("nan"), float("inf") and float("-inf") now work on
5414 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005415
Georg Brandl3ee81df2008-05-17 18:14:43 +00005416- Compiler now generates simpler and faster code for dictionary
5417 literals. The oparg for BUILD_MAP now indicates an estimated
5418 dictionary size. There is a new opcode, STORE_MAP, for adding
5419 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005420
Georg Brandl3ee81df2008-05-17 18:14:43 +00005421- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00005422
Georg Brandl3ee81df2008-05-17 18:14:43 +00005423- Issue #1620: New property decorator syntax was modifying the
5424 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00005425
Georg Brandl3ee81df2008-05-17 18:14:43 +00005426- Issue #1538: Avoid copying string in split/rsplit if the split char
5427 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005428
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005429- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005430 SystemError.
5431
Nick Coghlanef01d822007-12-03 12:55:17 +00005432- PEP 366: Allow explicit relative imports when executing modules
5433 inside packages with the -m switch via a new module level
5434 __package__ attribute.
5435
Georg Brandl3ee81df2008-05-17 18:14:43 +00005436- Issue #1402: Fix a crash on exit, when another thread is still
5437 running, and if the deallocation of its frames somehow calls the
5438 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005439

5441
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00005442- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005443 attribute of an empty cell object.
5444
Georg Brandl3ee81df2008-05-17 18:14:43 +00005445- Issue #1460: The utf-7 incremental decoder did not accept truncated
5446 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005447
Georg Brandl3ee81df2008-05-17 18:14:43 +00005448- Patch #1739468: Directories and zipfiles containing a __main__.py
5449 file can now be directly executed by passing their name to the
5450 interpreter. The directory/zipfile is automatically inserted as the
5451 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005452
Georg Brandl3ee81df2008-05-17 18:14:43 +00005453- Issue #1265: Fix a problem with sys.settrace, if the tracing
5454 function uses a generator expression when at the same time the
5455 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005456
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005457- sets and frozensets now have an isdisjoint() method.
5458
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005459- optimize the performance of builtin.sum().
5460
Neal Norwitz44f326e2007-10-05 05:29:17 +00005461- Fix warnings found by the new version of the Coverity checker.
5462
Georg Brandl21e99f42010-03-07 15:23:59 +00005463- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005464 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5465 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005466
Georg Brandl3ee81df2008-05-17 18:14:43 +00005467- Issue #1686386: Tuple's tp_repr did not take into account the
5468 possibility of having a self-referential tuple, which is possible
5469 from C code. Nor did object's tp_str consider that a type's tp_str
5470 could do something that could lead to an inifinite recursion.
5471 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5472 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005473
Georg Brandl3ee81df2008-05-17 18:14:43 +00005474- Issue #1164: It was possible to trigger deadlock when using the
5475 'print' statement to write to a file since the GIL was not released
5476 as needed. Now PyObject_Print() does the right thing along with
5477 various tp_print implementations of the built-in types and those in
5478 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005479
Georg Brandl3ee81df2008-05-17 18:14:43 +00005480- Issue #1147: Exceptions were directly allowing string exceptions in
5481 their throw() method even though string exceptions no longer
5482 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005483
Georg Brandl3ee81df2008-05-17 18:14:43 +00005484- Issue #1096: Prevent a segfault from getting the repr of a very
5485 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005486
Brett Cannon1e534b52007-09-07 04:18:30 +00005487- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005488 PyObject_Call() never calling back out to Python code to trigger
5489 recursion depth updates/checks. Required the creation of a static
5490 RuntimeError instance in case normalizing an exception put the
5491 recursion check value past its limit. Fixes crashers
5492 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005493
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494- Patch #1031213: Decode source line in SyntaxErrors back to its
5495 original source encoding.

5498 with %G.
5499
Georg Brandl3ee81df2008-05-17 18:14:43 +00005500- Prevent expandtabs() on string and unicode objects from causing a
5501 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00005502

Georg Brandla5ea6892007-06-01 11:33:33 +00005506
Neal Norwitz0ac60192007-05-27 04:08:54 +00005507- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005508 __*__ attributes. (Some already existed, e.g., __doc__ and
5509 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005510
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005511- Add -3 option to the interpreter to warn about features that are
5512 deprecated and will be changed/removed in Python 3.0.
5513
Georg Brandl2134e752007-05-21 20:34:16 +00005514- Patch #1686487: you can now pass any mapping after '**' in function
5515 calls.
5516
Collin Winter62903052007-05-18 23:11:24 +00005517- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005518 "except E as target:". This is to provide forwards compatibility
5519 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005520
Brett Cannon229cee22007-05-05 01:34:02 +00005521- Deprecate BaseException.message as per PEP 352.
5522
Georg Brandl3ee81df2008-05-17 18:14:43 +00005523- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005524 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005525
Vinay Sajip8549ce32007-05-06 17:53:37 +00005526- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005527 setting a plain string, ie don't expand to single letter identifiers.
5528
Raymond Hettinger13936692007-04-11 18:40:58 +00005529- Request #1191699: Slices can now be pickled.
5530
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005531- Request #1193128: str.translate() now allows a None argument for
5532 translations that only remove characters without re-mapping the
5533 remaining characters.
5534
Georg Brandl5cb76c12007-03-21 09:00:39 +00005535- Patch #1682205: a TypeError while unpacking an iterable is no longer
5536 masked by a generic one with the message "unpack non-sequence".
5537
Neal Norwitzaa754b72007-03-21 06:39:48 +00005538- Remove unused file Python/fmod.c.
5539
Guido van Rossum143b5642007-03-23 04:58:42 +00005540- Bug #1683368: The object.__init__() and object.__new__() methods are
5541 now stricter in rejecting excess arguments. The only time when
5542 either allows excess arguments is when it is not overridden and the
5543 other one is. For backwards compatibility, when both are
5544 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005545 warning later). Also, type.__init__() insists on the same signature
5546 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005547
Georg Brandl3ee81df2008-05-17 18:14:43 +00005548- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5549 object to complex using its __complex__() method before falling back
5550 to the __float__() method. Therefore, the functions in the cmath
5551 module now can operate on objects that define a __complex__()
5552 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005553
Georg Brandl3ee81df2008-05-17 18:14:43 +00005554- Patch #1623563: allow __class__ assignment for classes with
5555 __slots__. The old and the new class are still required to have the
5556 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005557
Georg Brandl3ee81df2008-05-17 18:14:43 +00005558- Patch #1642547: Fix an error/crash when encountering syntax errors
5559 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005561- Patch #1462488: Python no longer segfaults when
5562 ``object.__reduce_ex__()`` is called with an object that is faking
5563 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005564
Georg Brandl3ee81df2008-05-17 18:14:43 +00005565- Patch #1680015: Don't modify __slots__ tuple if it contains an
5566 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00005568- Patch #1444529: the builtin compile() now accepts keyword arguments.
5569
Georg Brandl7b9c5552007-03-12 14:30:05 +00005570- Bug #1678647: write a newline after printing an exception in any
5571 case, even when converting the value to a string failed.
5572
Georg Brandl871f1bc2007-03-12 13:17:36 +00005573- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005574 its argument, if it exists. If not, it will work like before. This
5575 allows customizing the output of dir() in the presence of a
5576 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005577
Collin Winter276887b2007-03-12 16:11:39 +00005578- Patch #922167: Python no longer segfaults when faced with infinitely
5579 self-recursive reload() calls (as reported by bug #742342).
5580
Georg Brandl3ee81df2008-05-17 18:14:43 +00005581- Patch #1675981: remove unreachable code from ``type.__new__()``
5582 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00005583
Georg Brandl3ee81df2008-05-17 18:14:43 +00005584- Patch #1491866: change the complex() constructor to allow
5585 parthensized forms. This means complex(repr(x)) now works instead of
5586 raising a ValueError.

6097 ".cpp" too.
6098
Facundo Batistad918a652007-04-24 13:54:38 +00006099- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006100 the client's request was successfully received, understood, and
6101 accepted. Now in these cases no error is raised in urllib (issue
6102 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00006103

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006110- Added a timeout parameter to the constructor of other protocols
6111 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6112 work started with create_connection() and timeout in httplib, and
6113 closes patch #723312.
6114
Vinay Sajip8549ce32007-05-06 17:53:37 +00006115- Patch #1676823: Added create_connection() to socket.py, which may be
6116 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006117 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006118
Martin v. Löwis0af33882007-03-23 13:27:15 +00006119- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006126- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
6127 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00006128 directories.
6129

6139
Georg Brandlf66b6032007-03-14 08:27:52 +00006140- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006141 AttributeError instead of an IOError when the server's response
6142 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006143
Georg Brandl3ee81df2008-05-17 18:14:43 +00006144- Patch #957650: "%var%" environment variable references are now
6145 properly expanded in ntpath.expandvars(), also "~user" home
6146 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00006147
Georg Brandl3ee81df2008-05-17 18:14:43 +00006148- Patch #1429539: pdb now correctly initializes the __main__ module
6149 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006150 correctly now.
6151
Georg Brandlbad6f192007-03-13 21:32:56 +00006152- The nonobvious commands.getstatus() function is now deprecated.

6158
Georg Brandl3ee81df2008-05-17 18:14:43 +00006159- Patch #1530482: add pydoc.render_doc() which returns the
6160 documentation for a thing instead of paging it to stdout, which
6161 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00006162
Georg Brandl3ee81df2008-05-17 18:14:43 +00006163- Patch #1533909: the timeit module now accepts callables in addition

6169 parameter which can be set to False to prevent the default
6170 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00006171
Georg Brandl9e6b4702007-03-13 18:15:41 +00006172- Patch #1581073: add a flag to textwrap that prevents the dropping of
6173 whitespace while wrapping.
6174
Georg Brandl92a6bae2007-03-13 17:43:32 +00006175- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006176 are set for invalid interpolation sequences that would lead to
6177 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00006178

6191
Georg Brandl94fe3f52007-03-13 09:32:11 +00006192- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00006193 field names in its exception message if you try to write a record
6194 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00006212

6220 returned string up to the first NUL character.
6221

6231
Georg Brandl3ee81df2008-05-17 18:14:43 +00006232- unittest now verifies more of its assumptions. In particular,
6233 TestCase and TestSuite subclasses (not instances) are no longer
6234 accepted in TestSuite.addTest(). This should cause no
6235 incompatibility since it never made sense with ordinary subclasses
6236 -- the failure just occurred later, with a more cumbersome
6237 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00006238

6246 given a unicode argument and os.listdir() returns unicode filenames.
6247
Georg Brandl3ee81df2008-05-17 18:14:43 +00006248- Patch #1673619: setup.py identifies extension modules it doesn't

6250 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006626 time so that opening a database previously created with the DB_DUP
6627 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6628 opens. Specifically: dictionary assignment to a DB object will
6629 replace all values for a given key when the database allows
6630 duplicate values. DB users should use DB.put(k, v) when they want
6631 to store duplicates; not DB[k] = v.

6638 characters with ASCII value less than 32. Also, it correctly quotes
6639 dots only if they occur on a single line, as opposed to the previous
6640 behavior of quoting dots if they are the second character of any
6641 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006642
