138 handles non-blocking readinto() returning None correctly.

141 SSLSocket.sendto() to match the corresponding socket methods. Also,
142 fix various SSLSocket methods to raise socket.error rather than an
143 unhelpful TypeError when called on an unconnected socket. Original patch
144 by Andrew Bennetts.
145
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000146- Issue #9826: OrderedDict.__repr__ can now handle self-referential

155 This prevents user-created self-referencing ordered dictionaries from
156 becoming permanently uncollectable GC garbage. The downside is that
157 removing __del__ means that the internal doubly-linked list has to wait for
158 GC collection rather than freeing memory immediately when the refcnt drops
159 to zero.
160
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000161- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000162 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000163 value.
164
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000165- Issue #9792: In case of connection failure, socket.create_connection()
166 would swallow the exception and raise a new one, making it impossible
167 to fetch the original errno, or to filter timeout errors. Now the
168 original error is re-raised.
169
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000170- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
171 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
172 be updated back after the system call. Original patch by Brian Brazil.
173
Antoine Pitroudca9de92010-09-04 17:52:26 +0000174- Issue #1100562: Fix deep-copying of objects derived from the list and
175 dict types. Patch by Michele Orrù and Björn Lindqvist.
176
Fred Drakea1e627d2010-09-03 03:55:50 +0000177- Issue #7005: Fixed output of None values for RawConfigParser.write and
178 ConfigParser.write.
179
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000180- Issue #808164: Fixed socket.close to avoid references to globals, to
181 avoid issues when socket.close is called from a __del__ method.
182
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000183- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
184 falling into recursion.
185
R. David Murray7c4bf552010-08-25 01:45:57 +0000186- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
187 character years even if the message contains RFC822 two character years.
188
Daniel Stutzbach91287322010-08-24 21:09:30 +0000189- Issue #8750: Fixed MutableSet's methods to correctly handle
190 reflexive operations, namely x -= x and x ^= x.
191
Victor Stinnercaafd772010-09-08 10:51:01 +0000192- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000193 error handling when accepting a new connection.
194
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000195- Issue #658749: asyncore's connect() method now correctly interprets winsock

202
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000203- Issue #9617: Signals received during a low-level write operation aren't
204 ignored by the buffered IO layer anymore.
205
Benjamin Peterson52c36052010-08-21 03:03:22 +0000206- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
207 are not held onto after they are deleted elsewhere.
208
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000209- Issue #9626: the view methods for collections.OrderedDict() were returning
210 the unordered versions inherited from dict. Those methods are now
211 overridden to provide ordered views.
212
Éric Araujo0389ae62010-08-14 03:07:46 +0000213- Issue #8688: MANIFEST files created by distutils now include a magic
214 comment indicating they are generated. Manually maintained MANIFESTs
215 without this marker will not be overwritten or removed.
216
Antoine Pitroue1436d12010-08-12 15:25:51 +0000217- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

224 patch by Jason V. Miller.
225
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000226- Issue #9551: Don't raise TypeError when setting the value to None for

230 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
231
Antoine Pitrou99009162010-08-09 22:51:24 +0000232- Issue #3757: thread-local objects now support cyclic garbage collection.

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

617 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
618 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
619 Previous versions returned a single u'\ufffd'.

629 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000873- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
874 the method could block indefinitely if called just before the event loop
875 started running. This also fixes the occasional freezes witnessed in
876 test_httpservers.
Antoine Pitroua6240402010-04-25 21:40:32 +0000877
Antoine Pitroufc69af12010-04-24 20:04:58 +0000878- Issue #5103: SSL handshake would ignore the socket timeout and block
879 indefinitely if the other end didn't respond.
880
Georg Brandlfee0f442010-05-22 21:26:21 +0000881- The do_handshake() method of SSL objects now adjusts the blocking mode of the
882 SSL structure if necessary (as other methods already do).

885
Georg Brandlfee0f442010-05-22 21:26:21 +0000886- Issue #5238: Calling makefile() on an SSL object would prevent the underlying
887 socket from being closed until all objects get truely destroyed.

Georg Brandlfee0f442010-05-22 21:26:21 +0000892- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
893 string "python" as the *ident*. openlog() arguments are all optional and
894 keywords.
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +0000895
Georg Brandlfee0f442010-05-22 21:26:21 +0000896- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
897 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitroua5c4b552010-04-22 23:33:02 +0000898 wanting to continue using the socket in clear-text mode, by disabling
899 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000974 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000999- Issue #7301: Add environment variable $PYTHONWARNINGS.
1000
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001001- Issue #8329: Don't return the same lists from select.select when no fds are
1002 changed.
1003
Georg Brandlfee0f442010-05-22 21:26:21 +00001004- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001005 on 64-bit machines. The shift count for either left or right shift is
1006 permitted to be up to sys.maxsize.
1007
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001008- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00001014- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1015 with a non-empty format string. This is an effort to future-proof user
1016 code. If a derived class does not currently implement __format__ but later
1017 adds its own __format__, it would most likely break user code that had
1018 supplied a format string. This will be changed to a DeprecationWaring in
1019 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001020

Georg Brandlfee0f442010-05-22 21:26:21 +00001052- Issue #8257: The Decimal construct now accepts a float instance directly,
1053 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001054

1057
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001058- collections.Counter() now supports a subtract() method.
1059
Georg Brandlfee0f442010-05-22 21:26:21 +00001060- The functools module now has a total_ordering() class decorator to simplify
1061 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00001069- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1070 InvalidOperation instead of returning False. (Comparisons involving a quiet
1071 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1072 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001074- Issue #2531: Comparison operations between floats and Decimal instances now
1075 return a result based on the numeric values of the operands; previously they
1076 returned an arbitrary result based on the relative ordering of id(float) and
1077 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001080 argument `-` which tells it to read files to compile from stdin. Each line is
1081 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001091- Comparisons using one of <, <=, >, >= between a complex instance and a
1092 Fractions instance now raise TypeError instead of returning True/False. This
1093 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1094 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001447- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1448 and add the additional members returned in an OSVERSIONINFOEX structure. The
1449 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001452- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1453 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1454 returning NULL. The macro now returns a statically allocated empty string
1455 instead.

1465 strings,
1466 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1467 numeric strings corresponding to subnormal values,
1468 (3) a memory leak for some values large enough to cause overflow, and
1469 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001500- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001501 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001502 Also, raise ValueError rather than TypeError when an unknown TIPC address
1503 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001507- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001508 file position when calling `truncate()`. It would previously change the file
1509 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001510 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1511
Georg Brandlba83f822010-03-14 09:50:54 +00001512- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1513 class used to represent files stored inside an archive. The new
1514 implementation is significantly faster and can be wrapped in a
1515 ``io.BufferedReader`` object for more speedups. It also solves an issue
1516 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001527- Issue #7748: Since unicode values are supported for some metadata options in
1528 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1529 encoded string for them. This ensures that the upload and register commands
1530 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00001599What's New in Python 2.7 alpha 2?
1600=================================
1601
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +00001602*Release date: 2010-01-09*

1604Core and Builtins
1605-----------------
1606
Georg Brandlba83f822010-03-14 09:50:54 +00001607- The ``__complex__()`` method is now looked up on the class of instances to
1608 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001609
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001610- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1611 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1612
Mark Dickinson1b34d252010-01-01 17:27:30 +00001613- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001614 DeprecationWarning when passed a float argument where an integer was expected.
1615 These functions and methods now raise TypeError instead. The majority of the
1616 effects of this change are in the extension modules, but some core functions
1617 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1618 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00001619
Benjamin Peterson0f02d392009-12-30 19:34:10 +00001620- Issue #7604: Deleting an unset slotted attribute did not raise an
1621 AttributeError.
1622

Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +00001627
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00001628- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
1629 used to drop the time part of the result.
1630
Georg Brandlba83f822010-03-14 09:50:54 +00001631- Issue #1811: Improve accuracy and cross-platform consistency for true division
1632 of integers: the result of a/b is now correctly rounded for ints a and b (at
1633 least on IEEE 754 platforms), and in particular does not depend on the
1634 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001635
Georg Brandlba83f822010-03-14 09:50:54 +00001636- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1637 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1638 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00001639
Georg Brandlba83f822010-03-14 09:50:54 +00001640- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +00001641 executables on OSX.
1642
Georg Brandlba83f822010-03-14 09:50:54 +00001643 These executables now work properly with the arch(1) command: ``arch -ppc
1644 python`` will start a universal binary version of python in PPC mode (unlike
1645 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00001646
Georg Brandlba83f822010-03-14 09:50:54 +00001647- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
1648 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00001649

Georg Brandlba83f822010-03-14 09:50:54 +00001659- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
1660 allowing for a maximum number of tasks within the pool to be completed by the
1661 worker before that worker is terminated, and a new one created to replace it.
Jesse Noller654ade32010-01-27 03:05:57 +00001662
Georg Brandlba83f822010-03-14 09:50:54 +00001663- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc

Antoine Pitrou80157252010-01-08 19:20:17 +00001667- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00001668 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1669 alternative to cPickle if you care about performance. Patch by Florent
Antoine Pitrou80157252010-01-08 19:20:17 +00001670 Xicluna.

Gregory P. Smith79a3eb12010-01-03 01:29:44 +00001687
Georg Brandlba83f822010-03-14 09:50:54 +00001688- Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager.
Ezio Melotti569e61f2009-12-30 06:14:51 +00001689 Initial patch by Brian Curtin.
1690
Georg Brandlba83f822010-03-14 09:50:54 +00001691- Distutils now correctly identifies the build architecture as "x86_64" when
1692 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +00001693

Georg Brandlba83f822010-03-14 09:50:54 +00001697- Issue #7552: Removed line feed in the base64 Authorization header in the
1698 Distutils upload command to avoid an error when PyPI reads it. This occurs on
1699 long passwords. Initial patch by JP St. Pierre.
Tarek Ziadé2421d562009-12-20 23:23:34 +00001700

Benjamin Petersonddd392c2009-12-13 19:19:07 +00001704- Issue #7349: Make methods of file objects in the io module accept None as an
1705 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1706 the same as passing no argument.
1707
Georg Brandlba83f822010-03-14 09:50:54 +00001708- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
1709 argument like other file objects.

Mark Dickinsona36507c2010-01-30 10:08:33 +00001729
Georg Brandlba83f822010-03-14 09:50:54 +00001730- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
1731 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
1732 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
1733 float arguments for integer format codes (other than 'L'): previously an
1734 attempt to pass a float resulted in a DeprecationWarning; now it gives a
1735 TypeError. For the 'L' format code (which previously had no warning) there is
1736 now a DeprecationWarning.

1785 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001786

Georg Brandlba83f822010-03-14 09:50:54 +00001801- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1802 decimal string that's guaranteed to round back to x under correct rounding
1803 (with round-half-to-even rounding mode). Previously it gave a string based on
1804 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1805 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1806 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001807
Georg Brandlba83f822010-03-14 09:50:54 +00001808- Issue #7117: On almost all platforms: float-to-string and string-to-float
1809 conversions within Python are now correctly rounded. Places these conversions
1810 occur include: str for floats and complex numbers; the float and complex
1811 constructors; old-style and new-style numeric formatting; serialization and
1812 deserialization of floats and complex numbers using marshal, pickle and json;
1813 parsing of float and imaginary literals in Python code; Decimal-to-float
1814 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001815
Georg Brandlba83f822010-03-14 09:50:54 +00001816 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1817 providing correctly-rounded strtod and dtoa C functions. This code is
1818 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1819 the C compiler. There may be a small number of platforms on which correct
1820 operation of this code cannot be guaranteed, so the code is not used: notably,
1821 this applies to platforms where the C double format is not IEEE 754 binary64,
1822 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1823 and Python's configure script is unable to determine how to change the FPU
1824 precision. On these platforms conversions use the platform strtod and dtoa,
1825 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001826
Georg Brandlba83f822010-03-14 09:50:54 +00001827- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1828 uses the correctly-rounded string <-> float conversions described above (when
1829 available), and so produces correctly rounded results that will display nicely
1830 under the float repr. There are two related small changes: (1) round now
1831 accepts any class with an ``__index__()`` method for its second argument (but
1832 no longer accepts floats for the second argument), and (2) an excessively
1833 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1834 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002052 untrackable objects are not tracked by the garbage collector. This can reduce
2053 the size of collections and therefore the garbage collection overhead on
2054 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00002060- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
2061 internal representation of integers, for performance reasons. Base 2**30 is
2062 enabled by default on 64-bit machines. Add --enable-big-digits option to
2063 configure, which overrides the default. Add sys.long_info structseq to
2064 provide information about the internal format.

2095
Georg Brandl29c6a282009-04-05 20:23:13 +00002096- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002097 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00002127- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2128 existing .py counterpart, override the co_filename attributes of all code
2129 objects if the original filename is obsolete (which can happen if the file has
2130 been renamed, moved, or if it is accessed through different paths). Patch by

2184
Georg Brandlba83f822010-03-14 09:50:54 +00002185- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2186 file objects with closefd=False. The file descriptor is still kept open but
2187 the file object behaves like a closed file. The ``FileIO`` object also got a
2188 new readonly attribute ``closefd``.

2207
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002208- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002209 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002211- On windows, ``os.chdir()`` given unicode was not working if
2212 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2213 this code path is really executed because I cannot move to such directory on
2214 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002216- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2217 element is temporarily replaced with an equivalent frozenset. But the
2218 eventual KeyError would always report the empty ``frozenset()`` as the missing
2219 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002239- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2240 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2241 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2242 of using the replace error handler in PyUnicode_DecodeUTF8().
2243
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002244- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002247- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3416 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3417 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3418 neither __int__ nor __long__, TypeError used to be raised (with a
3419 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3420 struct.error in other cases.

3423 argument with an __int__ method can be packed, but use of this feature
3424 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003617- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

3619 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3620 ``printf`` function, whereas PyString_FromFormat has an independent
3621 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003718 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3719 for catch_warnings() also led to an improvement in the raising of a
3720 DeprecationWarning related to warnings.warn_explicit().
3721
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003722- The deprecation warnings for the old camelCase threading API were removed.

3744
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003745- Issue #2975: When compiling several extension modules with Visual Studio 2008
3746 from the same python interpreter, some environment variables would grow
3747 without limit.
3748
Benjamin Peterson37346b22008-08-23 20:27:43 +00003749- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3750 exploitation of poor argument checking.
3751
Gerhard Häringef2276b2008-09-12 13:54:06 +00003752- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003786What's New in Python 2.6 beta 3?
3787================================
3788
Barry Warsaw07a4a382008-08-21 01:15:08 +00003789*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003790
3791Core and Builtins
3792-----------------
3793
Guido van Rossumf8402962008-08-20 15:01:50 +00003794- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3795 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3796 extensions do not automatically benefit from the class attribute
3797 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3798 to their tp_flags field if they care. This is a backwards
3799 compatibility feature; in 3.0, all types will use the cache by
3800 default.
3801
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003802- Keyword arguments can now follow starred arguments. (``f(a, *args,
3803 keyword=23)`` is now valid syntax.)
3804
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003805- ctypes function pointers that are COM methods have a boolean True
3806 value again.
3807
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003808- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3809 by denying s# to parse objects that have a releasebuffer procedure,
3810 and introducing s*.
3811
Georg Brandl1e13ea92008-08-11 09:07:59 +00003812- Issue #3537: Fix an assertion failure when an empty but presized dict
3813 object was stored in the freelist.
3814
Mark Dickinsonb6467572008-08-04 21:30:09 +00003815- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3816 ValueError consistently across platforms.
3817
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003818- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3819 (64bit Unix, for example), unichr() would truncate its argument and return
3820 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3821
Neal Norwitze7d8be82008-07-31 17:17:14 +00003822- Apply security patches from Apple.
3823
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003824- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3825 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3826
Antoine Pitrou92f82162008-07-25 22:22:08 +00003827- Issue #1819: function calls with several named parameters are now on
3828 average 35% faster (as measured by pybench).
3829
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003830- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3831 the python debugger steps into a class statement: the free variables (local
3832 variables defined in an outer scope) would be deleted from the outer scope.
3833
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003834- Issue #2620: Overflow checking when allocating or reallocating memory
3835 was not always being done properly in some python types and extension
3836 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3837 all been updated to perform better checks and places in the code that
3838 would previously leak memory on the error path when such an allocation
3839 failed have been fixed.

3842-------
3843

3845
Benjamin Petersone977ad42008-08-20 01:42:01 +00003846- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3847 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3848
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003849- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3850 version reported by these tools does not necessarily follow the python
3851 version numbering scheme, so the module is less strict when parsing it.
3852
Nick Coghlanf70385a2008-08-18 12:42:46 +00003853- Issue #2235: Added Py3k warnings for types which will become unhashable
3854 under the stricter __hash__ inheritance rules in 3.0. Several types
3855 which did not meet the rules for hash invariants and were already
3856 unhashable in 3.0 have now been explicitly flagged as unhashable in
3857 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3858 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3859
Brett Cannon88f801d2008-08-18 00:46:22 +00003860- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3868
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003869- Issue #3575: Incremental decoder's decode function now takes bytearray
3870 by using 's*' instead of 't#'.
3871
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003872- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003873 fails unicode conversion on 2nd parameter. (windows only)
3874
Georg Brandl222e2082010-08-01 22:27:39 +00003875- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003876 in a redirect.
3877

Brett Cannon721b1452008-08-16 22:00:27 +00003879 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003880
Facundo Batistaeb90b782008-08-16 14:44:07 +00003881- Issue #2776: fixed small issue when handling an URL with double slash
3882 after a 302 response in the case of not going through a proxy.
3883
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003884- Issue #2676: in the email package, content-type parsing was hanging on
3885 pathological input because of quadratic or exponential behaviour of a
3886 regular expression.
3887
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003888- Issue #3476: binary buffered reading through the new "io" library is now
3889 thread-safe.
3890
Brett Cannonbf3157b2008-08-14 05:00:03 +00003891- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3892 since mimetools itself is deprecated. Because modules are cached, all
3893 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3894
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003895- Issue #3134: shutil referenced undefined WindowsError symbol.
3896
Robert Schuppenies14646332008-08-10 11:01:53 +00003897- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3898 menu entries were not deleted.
3899
Brett Cannon83e81842008-08-09 23:30:55 +00003900- Copied the implementation of reduce() to _functools.reduce() to have a
3901 version that did not raise a DeprecationWarning under -3.
3902
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003903- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3904 a MemoryError rather than silently stop the iteration.
3905
Guido van Rossum59ce9012008-08-09 14:55:34 +00003906- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3907 to _sre.compile() will now be rejected. This should not affect anybody
3908 since the re.compile() function never generates invalid re-bytecode.
3909
Skip Montanaroa032bf42008-08-08 22:52:51 +00003910- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3911 upon first access it can be automatically initialized from the csv file if
3912 it wasn't initialized during instantiation.
3913
Brett Cannon3aa2a492008-08-06 22:28:09 +00003914- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3915 the reload() built-in has been removed.
3916
Brett Cannon7e30b672008-08-04 21:52:25 +00003917- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003918 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003929 asking for a specific length. This problem only affected files opened
3930 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003931

3976 regarding lack of coverage of new-style classes have also been
3977 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003980What's New in Python 2.6 beta 2?
3981================================
3982
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003983*Release date: 17-Jul-2008*
3984
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003985Core and Builtins
3986-----------------
3987
Georg Brandl3e483f62008-07-16 22:57:41 +00003988- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3989 its methods now allow for items objects that can be converted to
3990 an integer using operator.index().
3991
Mark Dickinson64b7e502008-07-16 09:40:03 +00003992- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3993 produced a ValueError instead of giving the correct float.
3994
Eric Smitha5fa5a22008-07-16 00:11:49 +00003995- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3996 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3997
Mark Dickinson7103aa42008-07-15 19:08:33 +00003998- Issue #3008: the float type has a new instance method 'float.hex'
3999 and a new class method 'float.fromhex' to convert floating-point
4000 numbers to and from hexadecimal strings, respectively.
4001
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004002- Issue #2235: __hash__ is once again inherited by default. To allow
4003 collections.Hashable to remain meaningful in the presence of the
4004 default hash implementation (object.__hash__), it is now possible
4005 to explicit block inheritance of hash by setting __hash__=None at
4006 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4007 level.
4008
Nick Coghlanb028f502008-07-13 14:52:36 +00004009- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4010 the parent module cannot be found while performing an absolute import.
4011 This means that an incorrectly defined __package__ attribute will
4012 now only prevent relative imports in that module rather than causing
4013 all imports from that module to fail.
4014
Nick Coghlan14ff9942008-07-08 14:21:42 +00004015- Issue #2517: Allow unicode messages in Exceptions again by correctly
4016 bypassing the instance dictionary when looking up __unicode__ on
4017 new-style classes.
4018
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004019- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4020 set to a custom object whose write() method happens to install
4021 another file in sys.stdout.
4022
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004023- Issue #3088: Corrected a race condition in classes derived from
4024 threading.local: the first member set by a thread could be saved in
4025 another thread's dictionary.
4026
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004027- Issue #3004: Minor change to slice.indices(): the start and stop
4028 arguments are now treated identically, making the behaviour easier
4029 to describe and understand. For example, slice(None, -10,
4030 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4031 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4032 10, -1).
4033
Georg Brandl278fc502008-07-19 12:46:12 +00004034- Issue #3219: Calling a function with repeated keyword arguments,
4035 f(a=2, a=23), would not cause a syntax error. This was a regression
4036 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004037
Georg Brandl278fc502008-07-19 12:46:12 +00004038- Issue #2862: Make int and float freelist management consistent with
4039 other freelists. Changes their CompactFreeList apis into
4040 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004041
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004042Library
4043-------
4044
Thomas Heller57adf222008-08-14 19:10:48 +00004045- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4046 api functions without holding the GIL, which could lead to a fatal
4047 error when they failed.
4048
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004049- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
4050
Jesse Noller7fb96402008-07-17 21:01:05 +00004051- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

4056
Jesse Noller13e9d582008-07-16 14:32:36 +00004057- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4058 ForkingPickler.register() to resolve conflict with ctypes.
4059
Vinay Sajip51e65192008-07-18 09:01:10 +00004060- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004061
Thomas Heller880f5292008-07-15 19:39:38 +00004062- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4063 a valid dlerror() message.
4064
Thomas Heller2bad6572008-07-15 17:19:50 +00004065- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4066 incomplete structure was created.
4067
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004068- Issue #3339: dummy_thread.acquire() should not return None.
4069
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004070- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4071
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004072- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004073
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004074- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4075 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004076 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004077 content-length. The problem had been corrected in the 2.4 branch, but never
4078 merged into trunk.
4079
Georg Brandle78fbcc2008-07-05 10:13:36 +00004080- Issue #2663: add filtering capability to shutil.copytree().
4081

4083
4084- Issue #1526: Allow more than 64k files to be added to Zip64 file.
4085
4086- Issue #1746: Correct handling of zipfile archive comments (previously
4087 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004088 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004089
Vinay Sajip51e65192008-07-18 09:01:10 +00004090- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004091 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004092
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004093- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4094 handling is now the same as that of other special attributes like __name__).
4095
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004096- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4097 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004548- Issue #1631171: Re-implement the 'warnings' module in C (the
4549 original Python code has been kept as backup). This will allow for
4550 using the 'warning's machinery in such places as the parser where
4551 use of pure Python code is not possible. Both the ``showarning()``
4552 and ``formatwarning()`` gain an optional 'line' argument which is
4553 not called by default for backwards-compatibility reasons. Setting
4554 ``warnings.showwarning()`` to an implementation that lacks support
4555 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004618- Issue #2550: The approach used by client/server code for obtaining
4619 ports to listen on in network-oriented tests has been refined in an
4620 effort to facilitate running multiple instances of the entire
4621 regression test suite in parallel without issue.
4622 test_support.bind_port() has been fixed such that it will always
4623 return a unique port -- which wasn't always the case with the
4624 previous implementation, especially if socket options had been set
4625 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4626 new implementation of bind_port() will actually raise an exception
4627 if it is passed an AF_INET/SOCK_STREAM socket with either the
4628 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4629 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4630 the socket it's been passed. This currently only applies to
4631 Windows. This option prevents any other sockets from binding to the
4632 host/port we've bound to, thus removing the possibility of the
4633 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4634 when a second SOCK_STREAM socket binds and accepts to a host/port
4635 that's already been bound by another socket. The optional preferred
4636 port parameter to bind_port() has been removed. Under no
4637 circumstances should tests be hard coding ports!
4638
4639 test_support.find_unused_port() has also been introduced, which will
4640 pass a temporary socket object to bind_port() in order to obtain an
4641 unused port. The temporary socket object is then closed and
4642 deleted, and the port is returned. This method should only be used
4643 for obtaining an unused port in order to pass to an external program
4644 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4645 a parameter to a server-oriented class that doesn't give you direct
4646 access to the underlying socket used.
4647
4648 Finally, test_support.HOST has been introduced, which should be used
4649 for the host argument of any relevant socket calls (i.e. bind and
4650 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004651
4652 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004653 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004654 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4655 test_asynchat and test_socket_ssl.
4656
Georg Brandl3ee81df2008-05-17 18:14:43 +00004657 It is now possible for multiple instances of the regression test
4658 suite to run in parallel without issue.

4814 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00004815 platform.machine() and platform.processor() will report this
4816 information as well.

4926
Fred Drakea8ee94b2008-03-01 02:45:07 +00004927- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004928 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00004937- Added the future_builtins module, which contains hex() and oct().
4938 These are the PEP 3127 version of these functions, designed to be
4939 compatible with the hex() and oct() builtins from Python 3.0. They
4940 differ slightly in their output formats from the existing, unchanged
4941 Python 2.6 builtins. The expected usage of the future_builtins
4942 module is:
4943 from future_builtins import hex, oct
4944
Eric Smith7ef40bf2008-02-20 23:34:22 +00004945- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4946 exponents for exponents with absolute value < 100. Follows C99
4947 standard. This is a change on Windows, which would use 3 digits.
4948 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4949 so that any alterations it does to the resulting string will be
4950 available in stringlib/formatter.h (for float.__format__).
4951
Eric Smith5a3c1352008-02-19 13:21:56 +00004952- Implemented PEP 3101, Advanced String Formatting. This adds a new
4953 builtin format(); a format() method for str and unicode; a
4954 __format__() method to object, str, unicode, int, long, float, and
4955 datetime; the class string.Formatter; and the C API
4956 PyObject_Format().
4957
Georg Brandl3ee81df2008-05-17 18:14:43 +00004958- Fixed several potential crashes, all caused by specially crafted
4959 __del__ methods exploiting objects in temporarily inconsistent
4960 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004961
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004962- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004963 prevent a possible crash: an Abstract Base Class would try to access
4964 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004965

Georg Brandl3ee81df2008-05-17 18:14:43 +00004969- Clear all free lists during a gc.collect() of the highest generation
4970 in order to allow pymalloc to free more arenas. Python may give back
4971 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004972
Georg Brandl3ee81df2008-05-17 18:14:43 +00004973- Issue #2045: Fix an infinite recursion triggered when printing a
4974 subclass of collections.defaultdict, if its default_factory is set
4975 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004976
Christian Heimesf75dbef2008-02-08 00:11:31 +00004977- Fixed a minor memory leak in dictobject.c. The content of the free
4978 list was not freed on interpreter shutdown.
4979
Georg Brandl21e99f42010-03-07 15:23:59 +00004980- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004981 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004982
Georg Brandl3ee81df2008-05-17 18:14:43 +00004983- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4984 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004985 to compact the internal free lists of pre-allocted ints and floats.
4986
Georg Brandl3ee81df2008-05-17 18:14:43 +00004987- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4988 calls. Python expected the return type int but the fork familie
4989 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004990
Georg Brandl3ee81df2008-05-17 18:14:43 +00004991- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00005003- Patch #1473257: generator objects gain a gi_code attribute. This is
5004 the same object as the func_code attribute of the function that
5005 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005006
Georg Brandl3ee81df2008-05-17 18:14:43 +00005007- Issue #1920: "while 0" statements were completely removed by the
5008 compiler, even in the presence of an "else" clause, which is
5009 supposed to be run when the condition is false. Now the compiler
5010 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005011
Guido van Rossumeead05f2008-01-24 18:21:02 +00005012- A few crashers fixed: weakref_in_del.py (issue #1377858);
5013 loosing_dict_ref.py (issue #1303614, test67.py);
5014 borrowed_ref_[34].py (not in tracker).
5015
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005016- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005017 suppressed while an extension is loaded by calling SetErrorMode in

5019
Georg Brandl3ee81df2008-05-17 18:14:43 +00005020- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005021 several extension methods and modules do not work without unicode
5022 support.
5023
Georg Brandl26543b12008-01-21 18:36:51 +00005024- Issue #1882: when compiling code from a string, encoding cookies in the
5025 second line of code were not always recognized correctly.
5026
Georg Brandl14404b62008-01-19 19:27:05 +00005027- Issue #1679: "0x" was taken as a valid integer literal.
5028
Georg Brandl6caad7d2008-01-26 14:19:22 +00005029- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005030 added.
5031
Christian Heimesc94e2b52008-01-14 04:13:37 +00005032- sys.float_info / PyFloat_GetInfo: The floating point information
5033 object was converted from a dict to a specialized structseq object.
5034
Georg Brandl3ee81df2008-05-17 18:14:43 +00005035- Patch #1816: Added sys.flags structseq. It exposes the status of
5036 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005037
Georg Brandl3ee81df2008-05-17 18:14:43 +00005038- Objects/structseq.c: Implemented new structseq representation. The
5039 patch makes structseqs (e.g. the return value of os.stat) more
5040 readable.

5049
Georg Brandl3ee81df2008-05-17 18:14:43 +00005050- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5051 envvar and sys.dont_write_bytecode attribute. All these can be set
5052 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005053
Georg Brandl3ee81df2008-05-17 18:14:43 +00005054- Improve some exception messages when Windows fails to load an
5055 extension module. Now we get for example '%1 is not a valid Win32
5056 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005063- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005064 and INF. float("nan"), float("inf") and float("-inf") now work on
5065 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005067- Compiler now generates simpler and faster code for dictionary
5068 literals. The oparg for BUILD_MAP now indicates an estimated
5069 dictionary size. There is a new opcode, STORE_MAP, for adding
5070 entries to the dictionary.

5100 file can now be directly executed by passing their name to the
5101 interpreter. The directory/zipfile is automatically inserted as the
5102 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005104- Issue #1265: Fix a problem with sys.settrace, if the tracing
5105 function uses a generator expression when at the same time the
5106 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005107

5113
Georg Brandl21e99f42010-03-07 15:23:59 +00005114- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005115 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5116 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005117
Georg Brandl3ee81df2008-05-17 18:14:43 +00005118- Issue #1686386: Tuple's tp_repr did not take into account the
5119 possibility of having a self-referential tuple, which is possible
5120 from C code. Nor did object's tp_str consider that a type's tp_str
5121 could do something that could lead to an inifinite recursion.
5122 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5123 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005124
Georg Brandl3ee81df2008-05-17 18:14:43 +00005125- Issue #1164: It was possible to trigger deadlock when using the
5126 'print' statement to write to a file since the GIL was not released
5127 as needed. Now PyObject_Print() does the right thing along with
5128 various tp_print implementations of the built-in types and those in
5129 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005130
Georg Brandl3ee81df2008-05-17 18:14:43 +00005131- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00005137
Brett Cannon1e534b52007-09-07 04:18:30 +00005138- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005139 PyObject_Call() never calling back out to Python code to trigger
5140 recursion depth updates/checks. Required the creation of a static
5141 RuntimeError instance in case normalizing an exception put the
5142 recursion check value past its limit. Fixes crashers
5143 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005144

Neal Norwitz0ac60192007-05-27 04:08:54 +00005158- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005159 __*__ attributes. (Some already existed, e.g., __doc__ and
5160 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005161
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005162- Add -3 option to the interpreter to warn about features that are
5163 deprecated and will be changed/removed in Python 3.0.
5164
Georg Brandl2134e752007-05-21 20:34:16 +00005165- Patch #1686487: you can now pass any mapping after '**' in function
5166 calls.
5167
Collin Winter62903052007-05-18 23:11:24 +00005168- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005169 "except E as target:". This is to provide forwards compatibility
5170 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005177- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005178 setting a plain string, ie don't expand to single letter identifiers.
5179
Raymond Hettinger13936692007-04-11 18:40:58 +00005180- Request #1191699: Slices can now be pickled.
5181
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005182- Request #1193128: str.translate() now allows a None argument for
5183 translations that only remove characters without re-mapping the
5184 remaining characters.
5185
Georg Brandl5cb76c12007-03-21 09:00:39 +00005186- Patch #1682205: a TypeError while unpacking an iterable is no longer

5190
Guido van Rossum143b5642007-03-23 04:58:42 +00005191- Bug #1683368: The object.__init__() and object.__new__() methods are
5192 now stricter in rejecting excess arguments. The only time when
5193 either allows excess arguments is when it is not overridden and the
5194 other one is. For backwards compatibility, when both are
5195 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005196 warning later). Also, type.__init__() insists on the same signature
5197 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005198
Georg Brandl3ee81df2008-05-17 18:14:43 +00005199- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5200 object to complex using its __complex__() method before falling back
5201 to the __float__() method. Therefore, the functions in the cmath
5202 module now can operate on objects that define a __complex__()
5203 method.

5207 same slot names.

5214 its type.

5220
Georg Brandl7b9c5552007-03-12 14:30:05 +00005221- Bug #1678647: write a newline after printing an exception in any
5222 case, even when converting the value to a string failed.
5223
Georg Brandl871f1bc2007-03-12 13:17:36 +00005224- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225 its argument, if it exists. If not, it will work like before. This
5226 allows customizing the output of dir() in the presence of a
5227 __getattr__().

5236 parthensized forms. This means complex(repr(x)) now works instead of
5237 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005238
Georg Brandlaa2321b2007-03-07 00:40:28 +00005239- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005240 makes the filenames the warning module prints much more sensible
5241 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005254- Patch #1674228: when assigning a slice (old-style), check for the
5255 sq_ass_slice instead of the sq_slice slot.
5256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005257- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00005792 AttributeError instead of an IOError when the server's response
5793 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005794

Georg Brandl3ee81df2008-05-17 18:14:43 +00005810- Patch #1530482: add pydoc.render_doc() which returns the

5825
Georg Brandl92a6bae2007-03-13 17:43:32 +00005826- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005827 are set for invalid interpolation sequences that would lead to
5828 errors on reading back those values.

5871 returned string up to the first NUL character.

5884 TestCase and TestSuite subclasses (not instances) are no longer
5885 accepted in TestSuite.addTest(). This should cause no
5886 incompatibility since it never made sense with ordinary subclasses
5887 -- the failure just occurred later, with a more cumbersome
5888 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006277 time so that opening a database previously created with the DB_DUP
6278 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6279 opens. Specifically: dictionary assignment to a DB object will
6280 replace all values for a given key when the database allows
6281 duplicate values. DB users should use DB.put(k, v) when they want
6282 to store duplicates; not DB[k] = v.

6290 dots only if they occur on a single line, as opposed to the previous
6291 behavior of quoting dots if they are the second character of any
6292 line.

6638 of w# format code incorrectly truncated the length to an int, even
6639 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6640 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006670- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6671 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
