107
Antoine Pitrou2c7d6852010-09-23 19:55:24 +0000108- Issue #9928: Properly initialize the types exported by the bz2 module.
109
Antoine Pitrou6391b342010-09-14 18:48:19 +0000110- Issue #9854: The default read() implementation in io.RawIOBase now
111 handles non-blocking readinto() returning None correctly.
112
Antoine Pitrouf7f390a2010-09-14 14:37:18 +0000113- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
114 SSLSocket.sendto() to match the corresponding socket methods. Also,
115 fix various SSLSocket methods to raise socket.error rather than an
116 unhelpful TypeError when called on an unconnected socket. Original patch
117 by Andrew Bennetts.
118
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000119- Issue #9826: OrderedDict.__repr__ can now handle self-referential

128 This prevents user-created self-referencing ordered dictionaries from
129 becoming permanently uncollectable GC garbage. The downside is that
130 removing __del__ means that the internal doubly-linked list has to wait for
131 GC collection rather than freeing memory immediately when the refcnt drops
132 to zero.
133
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000134- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000135 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000136 value.

Antoine Pitrouc818ed42010-09-07 21:40:25 +0000138- Issue #9792: In case of connection failure, socket.create_connection()
139 would swallow the exception and raise a new one, making it impossible
140 to fetch the original errno, or to filter timeout errors. Now the
141 original error is re-raised.
142
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000143- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
144 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
145 be updated back after the system call. Original patch by Brian Brazil.
146
Antoine Pitroudca9de92010-09-04 17:52:26 +0000147- Issue #1100562: Fix deep-copying of objects derived from the list and
148 dict types. Patch by Michele Orrù and Björn Lindqvist.
149

151 ConfigParser.write.
152
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000153- Issue #808164: Fixed socket.close to avoid references to globals, to
154 avoid issues when socket.close is called from a __del__ method.
155
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000156- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

160 character years even if the message contains RFC822 two character years.
161
Daniel Stutzbach91287322010-08-24 21:09:30 +0000162- Issue #8750: Fixed MutableSet's methods to correctly handle
163 reflexive operations, namely x -= x and x ^= x.
164
Victor Stinnercaafd772010-09-08 10:51:01 +0000165- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000166 error handling when accepting a new connection.

174 module now correctly return a set. (Patch by Eli Bendersky.)
175
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000176- Issue #9617: Signals received during a low-level write operation aren't
177 ignored by the buffered IO layer anymore.
178
Benjamin Peterson52c36052010-08-21 03:03:22 +0000179- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
180 are not held onto after they are deleted elsewhere.
181
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000182- Issue #9626: the view methods for collections.OrderedDict() were returning
183 the unordered versions inherited from dict. Those methods are now
184 overridden to provide ordered views.
185
Éric Araujo0389ae62010-08-14 03:07:46 +0000186- Issue #8688: MANIFEST files created by distutils now include a magic

203 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
204
Antoine Pitrou99009162010-08-09 22:51:24 +0000205- Issue #3757: thread-local objects now support cyclic garbage collection.

218 This is how it is supposed to work, wget and curl do the same. Previous
219 behavior was wrong.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000942 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

965-----------------
966
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000967- Issue #7301: Add environment variable $PYTHONWARNINGS.
968
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000969- Issue #8329: Don't return the same lists from select.select when no fds are
970 changed.
971
Georg Brandlfee0f442010-05-22 21:26:21 +0000972- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000973 on 64-bit machines. The shift count for either left or right shift is
974 permitted to be up to sys.maxsize.
975
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000976- Ensure that tokenization of identifiers is not affected by locale.

981
Georg Brandlfee0f442010-05-22 21:26:21 +0000982- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
983 with a non-empty format string. This is an effort to future-proof user
984 code. If a derived class does not currently implement __format__ but later
985 adds its own __format__, it would most likely break user code that had
986 supplied a format string. This will be changed to a DeprecationWaring in
987 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000988
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000989- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +00001014- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001015 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

Georg Brandlfee0f442010-05-22 21:26:21 +00001020- Issue #8257: The Decimal construct now accepts a float instance directly,
1021 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001022

1025
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001026- collections.Counter() now supports a subtract() method.
1027
Georg Brandlfee0f442010-05-22 21:26:21 +00001028- The functools module now has a total_ordering() class decorator to simplify
1029 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00001037- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1038 InvalidOperation instead of returning False. (Comparisons involving a quiet
1039 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1040 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001041
Georg Brandlfee0f442010-05-22 21:26:21 +00001042- Issue #2531: Comparison operations between floats and Decimal instances now
1043 return a result based on the numeric values of the operands; previously they
1044 returned an arbitrary result based on the relative ordering of id(float) and
1045 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001046
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001047- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001048 argument `-` which tells it to read files to compile from stdin. Each line is
1049 read on demand and the named file is compiled immediately. (Original patch by
1050 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00001055- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1056 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001057 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00001059- Comparisons using one of <, <=, >, >= between a complex instance and a
1060 Fractions instance now raise TypeError instead of returning True/False. This
1061 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1062 <=> complex, and complex <=> complex comparisons.

1171 the set of integer codes for which it was used differed between native packing
1172 and standard packing.)

1421 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1422 returning NULL. The macro now returns a statically allocated empty string
1423 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00001476 file position when calling `truncate()`. It would previously change the file
1477 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001478 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1481 class used to represent files stored inside an archive. The new
1482 implementation is significantly faster and can be wrapped in a
1483 ``io.BufferedReader`` object for more speedups. It also solves an issue
1484 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001495- Issue #7748: Since unicode values are supported for some metadata options in
1496 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1497 encoded string for them. This ensures that the upload and register commands
1498 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00001581- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001582 DeprecationWarning when passed a float argument where an integer was expected.
1583 These functions and methods now raise TypeError instead. The majority of the
1584 effects of this change are in the extension modules, but some core functions
1585 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1586 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00001769- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1770 decimal string that's guaranteed to round back to x under correct rounding
1771 (with round-half-to-even rounding mode). Previously it gave a string based on
1772 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1773 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1774 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001775
Georg Brandlba83f822010-03-14 09:50:54 +00001776- Issue #7117: On almost all platforms: float-to-string and string-to-float
1777 conversions within Python are now correctly rounded. Places these conversions
1778 occur include: str for floats and complex numbers; the float and complex
1779 constructors; old-style and new-style numeric formatting; serialization and
1780 deserialization of floats and complex numbers using marshal, pickle and json;
1781 parsing of float and imaginary literals in Python code; Decimal-to-float
1782 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001783
Georg Brandlba83f822010-03-14 09:50:54 +00001784 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1785 providing correctly-rounded strtod and dtoa C functions. This code is
1786 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1787 the C compiler. There may be a small number of platforms on which correct
1788 operation of this code cannot be guaranteed, so the code is not used: notably,
1789 this applies to platforms where the C double format is not IEEE 754 binary64,
1790 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1791 and Python's configure script is unable to determine how to change the FPU
1792 precision. On these platforms conversions use the platform strtod and dtoa,
1793 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001795- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1796 uses the correctly-rounded string <-> float conversions described above (when
1797 available), and so produces correctly rounded results that will display nicely
1798 under the float repr. There are two related small changes: (1) round now
1799 accepts any class with an ``__index__()`` method for its second argument (but
1800 no longer accepts floats for the second argument), and (2) an excessively
1801 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1802 raises an exception.

2152
Georg Brandlba83f822010-03-14 09:50:54 +00002153- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on

Georg Brandlba83f822010-03-14 09:50:54 +00002179- On windows, ``os.chdir()`` given unicode was not working if

2181 this code path is really executed because I cannot move to such directory on
2182 win2k)

2208 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

3584
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003585- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3586 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3587 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3588 ``printf`` function, whereas PyString_FromFormat has an independent
3589 implementation and uses "%zd" on all platforms for size_t values.
3590 This makes a difference on win64, where ``printf`` needs "%Id" to display
3591 64bit values.

3597 object; previously an int would be returned for small values. the __long__

Antoine Pitrou0668c622008-08-26 22:42:08 +00003611 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3612 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3613 when given a tuple of classes as second argument, were looking up
3614 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3615 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003686 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3687 for catch_warnings() also led to an improvement in the raising of a
3688 DeprecationWarning related to warnings.warn_explicit().
3689
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003690- The deprecation warnings for the old camelCase threading API were removed.
3691

3695
Christian Heimes1cc69632008-08-22 20:10:27 +00003696- Fixed two format strings in the _collections module.
3697

Gregory P. Smithd7122032008-09-02 05:36:11 +00003701- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
3702 non-integer floating point number.
3703
Vinay Sajip65d66e12008-09-04 07:31:21 +00003704- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

3711 _check_logger_class from multiprocessing.
3712
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003713- Issue #2975: When compiling several extension modules with Visual Studio 2008
3714 from the same python interpreter, some environment variables would grow
3715 without limit.
3716
Benjamin Peterson37346b22008-08-23 20:27:43 +00003717- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3718 exploitation of poor argument checking.
3719
Gerhard Häringef2276b2008-09-12 13:54:06 +00003720- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3721
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003722- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3723 remaining ones have "pysqlite_" prefix.
3724
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003725- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

3733 wrapper for warnings.catch_warnings() that makes it easier to check
3734 that expected warning messages are being reported.
3735
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003736- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003754What's New in Python 2.6 beta 3?
3755================================
3756
Barry Warsaw07a4a382008-08-21 01:15:08 +00003757*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003758
3759Core and Builtins
3760-----------------
3761
Guido van Rossumf8402962008-08-20 15:01:50 +00003762- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3763 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3764 extensions do not automatically benefit from the class attribute
3765 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3766 to their tp_flags field if they care. This is a backwards
3767 compatibility feature; in 3.0, all types will use the cache by
3768 default.
3769
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003770- Keyword arguments can now follow starred arguments. (``f(a, *args,
3771 keyword=23)`` is now valid syntax.)
3772
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003773- ctypes function pointers that are COM methods have a boolean True
3774 value again.
3775
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003776- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3777 by denying s# to parse objects that have a releasebuffer procedure,
3778 and introducing s*.
3779
Georg Brandl1e13ea92008-08-11 09:07:59 +00003780- Issue #3537: Fix an assertion failure when an empty but presized dict
3781 object was stored in the freelist.
3782
Mark Dickinsonb6467572008-08-04 21:30:09 +00003783- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3784 ValueError consistently across platforms.
3785
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003786- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3787 (64bit Unix, for example), unichr() would truncate its argument and return
3788 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3789
Neal Norwitze7d8be82008-07-31 17:17:14 +00003790- Apply security patches from Apple.
3791
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003792- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3793 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3794
Antoine Pitrou92f82162008-07-25 22:22:08 +00003795- Issue #1819: function calls with several named parameters are now on
3796 average 35% faster (as measured by pybench).
3797
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003798- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3799 the python debugger steps into a class statement: the free variables (local
3800 variables defined in an outer scope) would be deleted from the outer scope.
3801
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003802- Issue #2620: Overflow checking when allocating or reallocating memory
3803 was not always being done properly in some python types and extension
3804 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3805 all been updated to perform better checks and places in the code that
3806 would previously leak memory on the error path when such an allocation
3807 failed have been fixed.
3808
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003809Library
3810-------
3811
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003812- Issue #3612: Added some missing basic types in ctypes.wintypes.
3813
Benjamin Petersone977ad42008-08-20 01:42:01 +00003814- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3815 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3816
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003817- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3818 version reported by these tools does not necessarily follow the python
3819 version numbering scheme, so the module is less strict when parsing it.
3820
Nick Coghlanf70385a2008-08-18 12:42:46 +00003821- Issue #2235: Added Py3k warnings for types which will become unhashable
3822 under the stricter __hash__ inheritance rules in 3.0. Several types
3823 which did not meet the rules for hash invariants and were already
3824 unhashable in 3.0 have now been explicitly flagged as unhashable in
3825 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3826 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3827
Brett Cannon88f801d2008-08-18 00:46:22 +00003828- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3829 imported into the module but exposed as part of the module's API.
3830
Brett Cannon7b96f072008-08-18 00:41:11 +00003831- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3832
Brett Cannon46225e72008-08-18 00:36:52 +00003833- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003835- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3836
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003837- Issue #3575: Incremental decoder's decode function now takes bytearray
3838 by using 's*' instead of 't#'.
3839
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003840- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003841 fails unicode conversion on 2nd parameter. (windows only)
3842
Georg Brandl222e2082010-08-01 22:27:39 +00003843- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003844 in a redirect.
3845
Brett Cannonabe423e2008-08-16 21:47:07 +00003846- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003847 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003848
Facundo Batistaeb90b782008-08-16 14:44:07 +00003849- Issue #2776: fixed small issue when handling an URL with double slash
3850 after a 302 response in the case of not going through a proxy.
3851
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003852- Issue #2676: in the email package, content-type parsing was hanging on
3853 pathological input because of quadratic or exponential behaviour of a
3854 regular expression.
3855
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003856- Issue #3476: binary buffered reading through the new "io" library is now
3857 thread-safe.
3858
Brett Cannonbf3157b2008-08-14 05:00:03 +00003859- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3860 since mimetools itself is deprecated. Because modules are cached, all
3861 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3862
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003863- Issue #3134: shutil referenced undefined WindowsError symbol.
3864
Robert Schuppenies14646332008-08-10 11:01:53 +00003865- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3866 menu entries were not deleted.
3867
Brett Cannon83e81842008-08-09 23:30:55 +00003868- Copied the implementation of reduce() to _functools.reduce() to have a
3869 version that did not raise a DeprecationWarning under -3.
3870
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003871- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3872 a MemoryError rather than silently stop the iteration.
3873
Guido van Rossum59ce9012008-08-09 14:55:34 +00003874- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3875 to _sre.compile() will now be rejected. This should not affect anybody
3876 since the re.compile() function never generates invalid re-bytecode.
3877
Skip Montanaroa032bf42008-08-08 22:52:51 +00003878- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3879 upon first access it can be automatically initialized from the csv file if
3880 it wasn't initialized during instantiation.
3881
Brett Cannon3aa2a492008-08-06 22:28:09 +00003882- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3883 the reload() built-in has been removed.
3884
Brett Cannon7e30b672008-08-04 21:52:25 +00003885- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003886 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003897 asking for a specific length. This problem only affected files opened
3898 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003899

3924 file name rather than a ZipInfo instance, so files are extracted with
3925 mode 0600 rather than 000 under Unix.
3926
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003927- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3928 argument in python 2.5, this broke code that subclassed Popen to include its
3929 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3944 regarding lack of coverage of new-style classes have also been
3945 removed, since the coverage is now fairly reasonable.

3955
Georg Brandl3e483f62008-07-16 22:57:41 +00003956- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3957 its methods now allow for items objects that can be converted to
3958 an integer using operator.index().
3959
Mark Dickinson64b7e502008-07-16 09:40:03 +00003960- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3961 produced a ValueError instead of giving the correct float.
3962
Eric Smitha5fa5a22008-07-16 00:11:49 +00003963- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3964 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3965
Mark Dickinson7103aa42008-07-15 19:08:33 +00003966- Issue #3008: the float type has a new instance method 'float.hex'

Nick Coghlan6d6bd442008-07-15 15:40:22 +00003970- Issue #2235: __hash__ is once again inherited by default. To allow
3971 collections.Hashable to remain meaningful in the presence of the
3972 default hash implementation (object.__hash__), it is now possible
3973 to explicit block inheritance of hash by setting __hash__=None at
3974 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3975 level.
3976
Nick Coghlanb028f502008-07-13 14:52:36 +00003977- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3978 the parent module cannot be found while performing an absolute import.
3979 This means that an incorrectly defined __package__ attribute will
3980 now only prevent relative imports in that module rather than causing
3981 all imports from that module to fail.
3982
Nick Coghlan14ff9942008-07-08 14:21:42 +00003983- Issue #2517: Allow unicode messages in Exceptions again by correctly

3994
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003995- Issue #3004: Minor change to slice.indices(): the start and stop
3996 arguments are now treated identically, making the behaviour easier
3997 to describe and understand. For example, slice(None, -10,
3998 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3999 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4000 10, -1).

4043 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004044 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00004454 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004455
4456 This is controlled by the configure argument ``--with-universal-archs``:
4457

4459
4460 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4461
4462 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4463
4464 This option should be used in combination with ``--enable-universalsdk=``.

4503 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00004504
Christian Heimese74c8f22008-04-19 02:23:57 +00004505- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004516- Issue #1631171: Re-implement the 'warnings' module in C (the
4517 original Python code has been kept as backup). This will allow for
4518 using the 'warning's machinery in such places as the parser where
4519 use of pure Python code is not possible. Both the ``showarning()``
4520 and ``formatwarning()`` gain an optional 'line' argument which is
4521 not called by default for backwards-compatibility reasons. Setting
4522 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00004586- Issue #2550: The approach used by client/server code for obtaining
4587 ports to listen on in network-oriented tests has been refined in an
4588 effort to facilitate running multiple instances of the entire
4589 regression test suite in parallel without issue.
4590 test_support.bind_port() has been fixed such that it will always
4591 return a unique port -- which wasn't always the case with the
4592 previous implementation, especially if socket options had been set
4593 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4594 new implementation of bind_port() will actually raise an exception
4595 if it is passed an AF_INET/SOCK_STREAM socket with either the
4596 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4597 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4598 the socket it's been passed. This currently only applies to
4599 Windows. This option prevents any other sockets from binding to the
4600 host/port we've bound to, thus removing the possibility of the
4601 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4602 when a second SOCK_STREAM socket binds and accepts to a host/port
4603 that's already been bound by another socket. The optional preferred
4604 port parameter to bind_port() has been removed. Under no
4605 circumstances should tests be hard coding ports!
4606
4607 test_support.find_unused_port() has also been introduced, which will
4608 pass a temporary socket object to bind_port() in order to obtain an
4609 unused port. The temporary socket object is then closed and
4610 deleted, and the port is returned. This method should only be used
4611 for obtaining an unused port in order to pass to an external program
4612 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4613 a parameter to a server-oriented class that doesn't give you direct
4614 access to the underlying socket used.
4615
4616 Finally, test_support.HOST has been introduced, which should be used
4617 for the host argument of any relevant socket calls (i.e. bind and
4618 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004619
4620 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004621 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004622 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4623 test_asynchat and test_socket_ssl.
4624
Georg Brandl3ee81df2008-05-17 18:14:43 +00004625 It is now possible for multiple instances of the regression test
4626 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004792- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
4793 values on 32-bit vs. 64-bit python interpreters. Both were correct,
4794 but they now both return a signed integer object for consistency.

Facundo Batistafc2d0102008-02-23 12:01:13 +00004904
Eric Smitha73fbe72008-02-23 03:09:44 +00004905- Added the future_builtins module, which contains hex() and oct().
4906 These are the PEP 3127 version of these functions, designed to be
4907 compatible with the hex() and oct() builtins from Python 3.0. They
4908 differ slightly in their output formats from the existing, unchanged
4909 Python 2.6 builtins. The expected usage of the future_builtins
4910 module is:
4911 from future_builtins import hex, oct
4912
Eric Smith7ef40bf2008-02-20 23:34:22 +00004913- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4914 exponents for exponents with absolute value < 100. Follows C99
4915 standard. This is a change on Windows, which would use 3 digits.
4916 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4917 so that any alterations it does to the resulting string will be
4918 available in stringlib/formatter.h (for float.__format__).
4919
Eric Smith5a3c1352008-02-19 13:21:56 +00004920- Implemented PEP 3101, Advanced String Formatting. This adds a new
4921 builtin format(); a format() method for str and unicode; a
4922 __format__() method to object, str, unicode, int, long, float, and
4923 datetime; the class string.Formatter; and the C API
4924 PyObject_Format().
4925
Georg Brandl3ee81df2008-05-17 18:14:43 +00004926- Fixed several potential crashes, all caused by specially crafted
4927 __del__ methods exploiting objects in temporarily inconsistent
4928 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004929
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004930- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004931 prevent a possible crash: an Abstract Base Class would try to access
4932 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004933
Georg Brandl3ee81df2008-05-17 18:14:43 +00004934- Fixed repr() and str() of complex numbers with infinity or nan as
4935 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004937- Clear all free lists during a gc.collect() of the highest generation
4938 in order to allow pymalloc to free more arenas. Python may give back
4939 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004940
Georg Brandl3ee81df2008-05-17 18:14:43 +00004941- Issue #2045: Fix an infinite recursion triggered when printing a
4942 subclass of collections.defaultdict, if its default_factory is set
4943 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004944
Christian Heimesf75dbef2008-02-08 00:11:31 +00004945- Fixed a minor memory leak in dictobject.c. The content of the free
4946 list was not freed on interpreter shutdown.
4947
Georg Brandl21e99f42010-03-07 15:23:59 +00004948- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004949 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004950
Georg Brandl3ee81df2008-05-17 18:14:43 +00004951- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4952 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004953 to compact the internal free lists of pre-allocted ints and floats.
4954
Georg Brandl3ee81df2008-05-17 18:14:43 +00004955- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4956 calls. Python expected the return type int but the fork familie
4957 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004958
Georg Brandl3ee81df2008-05-17 18:14:43 +00004959- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4960 appear in the same code unit.

4969 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004970
Georg Brandl3ee81df2008-05-17 18:14:43 +00004971- Patch #1473257: generator objects gain a gi_code attribute. This is
4972 the same object as the func_code attribute of the function that
4973 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004974
Georg Brandl3ee81df2008-05-17 18:14:43 +00004975- Issue #1920: "while 0" statements were completely removed by the
4976 compiler, even in the presence of an "else" clause, which is
4977 supposed to be run when the condition is false. Now the compiler
4978 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004979
Guido van Rossumeead05f2008-01-24 18:21:02 +00004980- A few crashers fixed: weakref_in_del.py (issue #1377858);
4981 loosing_dict_ref.py (issue #1303614, test67.py);
4982 borrowed_ref_[34].py (not in tracker).
4983
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004984- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004985 suppressed while an extension is loaded by calling SetErrorMode in
4986 dynload_win.c. The error is still reported properly.
4987
Georg Brandl3ee81df2008-05-17 18:14:43 +00004988- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004989 several extension methods and modules do not work without unicode
4990 support.
4991
Georg Brandl26543b12008-01-21 18:36:51 +00004992- Issue #1882: when compiling code from a string, encoding cookies in the
4993 second line of code were not always recognized correctly.
4994
Georg Brandl14404b62008-01-19 19:27:05 +00004995- Issue #1679: "0x" was taken as a valid integer literal.
4996
Georg Brandl6caad7d2008-01-26 14:19:22 +00004997- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004998 added.
4999
Christian Heimesc94e2b52008-01-14 04:13:37 +00005000- sys.float_info / PyFloat_GetInfo: The floating point information
5001 object was converted from a dict to a specialized structseq object.
5002
Georg Brandl3ee81df2008-05-17 18:14:43 +00005003- Patch #1816: Added sys.flags structseq. It exposes the status of
5004 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005005
Georg Brandl3ee81df2008-05-17 18:14:43 +00005006- Objects/structseq.c: Implemented new structseq representation. The
5007 patch makes structseqs (e.g. the return value of os.stat) more
5008 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005009
Georg Brandl3ee81df2008-05-17 18:14:43 +00005010- Patch #1700288: added a type attribute cache that caches method
5011 accesses, resulting in speedups in heavily object-oriented code.

5019 envvar and sys.dont_write_bytecode attribute. All these can be set
5020 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005021
Georg Brandl3ee81df2008-05-17 18:14:43 +00005022- Improve some exception messages when Windows fails to load an
5023 extension module. Now we get for example '%1 is not a valid Win32
5024 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005025

Georg Brandl3ee81df2008-05-17 18:14:43 +00005083 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5084 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005085
Georg Brandl3ee81df2008-05-17 18:14:43 +00005086- Issue #1686386: Tuple's tp_repr did not take into account the
5087 possibility of having a self-referential tuple, which is possible
5088 from C code. Nor did object's tp_str consider that a type's tp_str
5089 could do something that could lead to an inifinite recursion.
5090 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5091 issues.

5094 'print' statement to write to a file since the GIL was not released
5095 as needed. Now PyObject_Print() does the right thing along with
5096 various tp_print implementations of the built-in types and those in
5097 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005107 PyObject_Call() never calling back out to Python code to trigger
5108 recursion depth updates/checks. Required the creation of a static

5158
Guido van Rossum143b5642007-03-23 04:58:42 +00005159- Bug #1683368: The object.__init__() and object.__new__() methods are
5160 now stricter in rejecting excess arguments. The only time when
5161 either allows excess arguments is when it is not overridden and the
5162 other one is. For backwards compatibility, when both are
5163 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005164 warning later). Also, type.__init__() insists on the same signature
5165 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005167- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5168 object to complex using its __complex__() method before falling back
5169 to the __float__() method. Therefore, the functions in the cmath
5170 module now can operate on objects that define a __complex__()
5171 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005189- Bug #1678647: write a newline after printing an exception in any
5190 case, even when converting the value to a string failed.
5191
Georg Brandl871f1bc2007-03-12 13:17:36 +00005192- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005193 its argument, if it exists. If not, it will work like before. This
5194 allows customizing the output of dir() in the presence of a
5195 __getattr__().

5205 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005206
Georg Brandlaa2321b2007-03-07 00:40:28 +00005207- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005208 makes the filenames the warning module prints much more sensible
5209 when a PYTHONSTARTUP file is used.

5223 sq_ass_slice instead of the sq_slice slot.
5224
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225- When printing an unraisable error, don't print exceptions. before

5793
Georg Brandl92a6bae2007-03-13 17:43:32 +00005794- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005795 are set for invalid interpolation sequences that would lead to
5796 errors on reading back those values.

5852 TestCase and TestSuite subclasses (not instances) are no longer
5853 accepted in TestSuite.addTest(). This should cause no
5854 incompatibility since it never made sense with ordinary subclasses
5855 -- the failure just occurred later, with a more cumbersome
5856 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006142- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006143 that the SMTP.starttls() caller no longer needs to call ehlo()
6144 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006145 does not claim to support starttls. Adds the
6146 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00006245 time so that opening a database previously created with the DB_DUP
6246 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6247 opens. Specifically: dictionary assignment to a DB object will

Georg Brandl3ee81df2008-05-17 18:14:43 +00006530 periodic threadstate and signal checking in tight loops. By
6531 default, this option is turned-off. It should only be enabled in
6532 debugged, performance critical applications.

6604
Georg Brandl3ee81df2008-05-17 18:14:43 +00006605- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6606 of w# format code incorrectly truncated the length to an int, even
6607 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6608 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006638- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6639 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
