626 object with custom buffering from two threads at once.
627
Antoine Pitrou7f081022010-10-27 18:43:21 +0000628- Issue #5027: The standard ``xml`` namespace is now understood by
629 xml.sax.saxutils.XMLGenerator as being bound to

667 received. Now sendall() properly calls signal handlers if necessary,
668 and retries sending if these returned successfully, including on sockets

678
Antoine Pitrou6391b342010-09-14 18:48:19 +0000679- Issue #9854: The default read() implementation in io.RawIOBase now
680 handles non-blocking readinto() returning None correctly.
681

683 SSLSocket.sendto() to match the corresponding socket methods. Also,
684 fix various SSLSocket methods to raise socket.error rather than an
685 unhelpful TypeError when called on an unconnected socket. Original patch
686 by Andrew Bennetts.
687
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000688- Issue #9826: OrderedDict.__repr__ can now handle self-referential
689 values: d['x'] = d.
690
Victor Stinner8fc843b2010-09-17 23:35:50 +0000691- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.

Antoine Pitroue4195e82010-09-12 14:56:27 +0000693- Issue #9837: The read() method of ZipExtFile objects (as returned by
694 ZipFile.open()) could return more bytes than requested.
695
Raymond Hettinger20397532010-09-12 02:11:45 +0000696- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
697 This prevents user-created self-referencing ordered dictionaries from
698 becoming permanently uncollectable GC garbage. The downside is that
699 removing __del__ means that the internal doubly-linked list has to wait for
700 GC collection rather than freeing memory immediately when the refcnt drops
701 to zero.
702
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000703- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000704 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000705 value.
706
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000707- Issue #9792: In case of connection failure, socket.create_connection()
708 would swallow the exception and raise a new one, making it impossible
709 to fetch the original errno, or to filter timeout errors. Now the
710 original error is re-raised.
711
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000712- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
713 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
714 be updated back after the system call. Original patch by Brian Brazil.
715
Antoine Pitroudca9de92010-09-04 17:52:26 +0000716- Issue #1100562: Fix deep-copying of objects derived from the list and

720 ConfigParser.write.
721
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000722- Issue #808164: Fixed socket.close to avoid references to globals, to
723 avoid issues when socket.close is called from a __del__ method.
724
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000725- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

730 falling into recursion.
731
R. David Murray7c4bf552010-08-25 01:45:57 +0000732- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
733 character years even if the message contains RFC822 two character years.
734
Daniel Stutzbach91287322010-08-24 21:09:30 +0000735- Issue #8750: Fixed MutableSet's methods to correctly handle
736 reflexive operations, namely x -= x and x ^= x.
737
Victor Stinnercaafd772010-09-08 10:51:01 +0000738- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

747 module now correctly return a set. (Patch by Eli Bendersky.)
748
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000749- Issue #9617: Signals received during a low-level write operation aren't
750 ignored by the buffered IO layer anymore.
751
Benjamin Peterson52c36052010-08-21 03:03:22 +0000752- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
753 are not held onto after they are deleted elsewhere.
754
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000755- Issue #9626: the view methods for collections.OrderedDict() were returning
756 the unordered versions inherited from dict. Those methods are now
757 overridden to provide ordered views.
758
Éric Araujo0389ae62010-08-14 03:07:46 +0000759- Issue #8688: MANIFEST files created by distutils now include a magic
760 comment indicating they are generated. Manually maintained MANIFESTs
761 without this marker will not be overwritten or removed.
762
Antoine Pitroue1436d12010-08-12 15:25:51 +0000763- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
764 and a BadZipfile error is raised if it doesn't match (as used to be the
765 case in Python 2.5 and earlier).
766
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000767- Issue #9550: a BufferedReader could issue an additional read when the
768 original read request had been satisfied, which could block indefinitely
769 when the underlying raw IO channel was e.g. a socket. Report and original
770 patch by Jason V. Miller.
771
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000772- Issue #9551: Don't raise TypeError when setting the value to None for
773 SafeConfigParser instances constructed with allow_no_value == True.
774
Antoine Pitrou8cdede42010-08-10 00:04:13 +0000775- Issue #6915: Under Windows, os.listdir() didn't release the Global

791 This is how it is supposed to work, wget and curl do the same. Previous
792 behavior was wrong.
793

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001160- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

1162 of the number of bytes specified by the start byte.
1163 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1164 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1176 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00001439- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
1440 string "python" as the *ident*. openlog() arguments are all optional and
1441 keywords.

R. David Murray1a14d3d2010-04-12 16:35:19 +00001473- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandlfee0f442010-05-22 21:26:21 +00001474 filename and date, conforming to the 'standards' they were originally designed
1475 to follow. This improves compatibility with patch tools.

Georg Brandlfee0f442010-05-22 21:26:21 +00001520- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001521 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1522 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1523 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1544-----------------
1545
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001546- Issue #7301: Add environment variable $PYTHONWARNINGS.
1547
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001548- Issue #8329: Don't return the same lists from select.select when no fds are
1549 changed.
1550
Georg Brandlfee0f442010-05-22 21:26:21 +00001551- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001552 on 64-bit machines. The shift count for either left or right shift is
1553 permitted to be up to sys.maxsize.
1554
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001555- Ensure that tokenization of identifiers is not affected by locale.
1556
Georg Brandlfee0f442010-05-22 21:26:21 +00001557- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001558
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001559- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1560
Georg Brandlfee0f442010-05-22 21:26:21 +00001561- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1562 with a non-empty format string. This is an effort to future-proof user
1563 code. If a derived class does not currently implement __format__ but later
1564 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001565 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001566 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001567
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001568- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00001581- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001582 (SIGINT). If an error occurs while importing the site module, the error is
1583 printed and Python exits. Initialize the GIL before importing the site

1598
Georg Brandlfee0f442010-05-22 21:26:21 +00001599- Issue #8257: The Decimal construct now accepts a float instance directly,
1600 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001601
1602 >>> Decimal(1.1)
1603 Decimal('1.100000000000000088817841970012523233890533447265625')
1604
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001605- collections.Counter() now supports a subtract() method.
1606
Georg Brandlfee0f442010-05-22 21:26:21 +00001607- The functools module now has a total_ordering() class decorator to simplify
1608 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001609
Georg Brandlfee0f442010-05-22 21:26:21 +00001610- The functools module also adds cmp_to_key() as a tool to transition old-style
1611 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001612

Georg Brandlfee0f442010-05-22 21:26:21 +00001616- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1617 InvalidOperation instead of returning False. (Comparisons involving a quiet
1618 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1619 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001620
Georg Brandlfee0f442010-05-22 21:26:21 +00001621- Issue #2531: Comparison operations between floats and Decimal instances now
1622 return a result based on the numeric values of the operands; previously they
1623 returned an arbitrary result based on the relative ordering of id(float) and
1624 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001625
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001626- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001627 argument `-` which tells it to read files to compile from stdin. Each line is
1628 read on demand and the named file is compiled immediately. (Original patch by
1629 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00001634- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1635 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001636 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001637
Georg Brandlfee0f442010-05-22 21:26:21 +00001638- Comparisons using one of <, <=, >, >= between a complex instance and a
1639 Fractions instance now raise TypeError instead of returning True/False. This
1640 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1641 <=> complex, and complex <=> complex comparisons.

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001652- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001653 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1654 silenced.

2004 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2005 returning NULL. The macro now returns a statically allocated empty string
2006 instead.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002058- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002059 file position when calling `truncate()`. It would previously change the file
2060 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002061 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2062

2064 class used to represent files stored inside an archive. The new
2065 implementation is significantly faster and can be wrapped in a
2066 ``io.BufferedReader`` object for more speedups. It also solves an issue
2067 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2080 encoded string for them. This ensures that the upload and register commands

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00002150What's New in Python 2.7 alpha 2?
2151=================================
2152
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +00002153*Release date: 2010-01-09*

2156-----------------
2157
Georg Brandlba83f822010-03-14 09:50:54 +00002158- The ``__complex__()`` method is now looked up on the class of instances to
2159 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00002160
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002161- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2162 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2163
Mark Dickinson1b34d252010-01-01 17:27:30 +00002164- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002165 DeprecationWarning when passed a float argument where an integer was expected.
2166 These functions and methods now raise TypeError instead. The majority of the
2167 effects of this change are in the extension modules, but some core functions
2168 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2169 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00002170
Benjamin Peterson0f02d392009-12-30 19:34:10 +00002171- Issue #7604: Deleting an unset slotted attribute did not raise an
2172 AttributeError.
2173
Georg Brandlba83f822010-03-14 09:50:54 +00002174- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)

Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +00002178
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00002179- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
2180 used to drop the time part of the result.
2181
Georg Brandlba83f822010-03-14 09:50:54 +00002182- Issue #1811: Improve accuracy and cross-platform consistency for true division
2183 of integers: the result of a/b is now correctly rounded for ints a and b (at
2184 least on IEEE 754 platforms), and in particular does not depend on the
2185 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00002186
Georg Brandlba83f822010-03-14 09:50:54 +00002187- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
2188 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
2189 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00002190

Ronald Oussoren92919a62009-12-24 13:30:58 +00002192 executables on OSX.
2193
Georg Brandlba83f822010-03-14 09:50:54 +00002194 These executables now work properly with the arch(1) command: ``arch -ppc
2195 python`` will start a universal binary version of python in PPC mode (unlike
2196 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00002197
Georg Brandlba83f822010-03-14 09:50:54 +00002198- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
2199 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00002200
Benjamin Peterson4895af42009-12-13 16:36:53 +00002201- Issue #7491: Metaclass's __cmp__ method was ignored.

Georg Brandlba83f822010-03-14 09:50:54 +00002210- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
2211 allowing for a maximum number of tasks within the pool to be completed by the
2212 worker before that worker is terminated, and a new one created to replace it.
Jesse Noller654ade32010-01-27 03:05:57 +00002213
Georg Brandlba83f822010-03-14 09:50:54 +00002214- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc

2216 Arfrever.
Tarek Ziadéc25417f2010-01-08 23:42:23 +00002217
Antoine Pitrou80157252010-01-08 19:20:17 +00002218- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00002219 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
2220 alternative to cPickle if you care about performance. Patch by Florent

Georg Brandlba83f822010-03-14 09:50:54 +00002239- Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager.
Ezio Melotti569e61f2009-12-30 06:14:51 +00002240 Initial patch by Brian Curtin.
2241
Georg Brandlba83f822010-03-14 09:50:54 +00002242- Distutils now correctly identifies the build architecture as "x86_64" when

Benjamin Petersonddd392c2009-12-13 19:19:07 +00002255- Issue #7349: Make methods of file objects in the io module accept None as an
2256 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
2257 the same as passing no argument.
2258
Georg Brandlba83f822010-03-14 09:50:54 +00002259- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
2260 argument like other file objects.
Benjamin Petersonc4771d22009-12-13 17:31:31 +00002261

Mark Dickinsona36507c2010-01-30 10:08:33 +00002280
Georg Brandlba83f822010-03-14 09:50:54 +00002281- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
2282 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2283 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2284 float arguments for integer format codes (other than 'L'): previously an
2285 attempt to pass a float resulted in a DeprecationWarning; now it gives a
2286 TypeError. For the 'L' format code (which previously had no warning) there is
2287 now a DeprecationWarning.

2336 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002337

Georg Brandlba83f822010-03-14 09:50:54 +00002352- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2353 decimal string that's guaranteed to round back to x under correct rounding
2354 (with round-half-to-even rounding mode). Previously it gave a string based on
2355 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2356 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2357 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002358
Georg Brandlba83f822010-03-14 09:50:54 +00002359- Issue #7117: On almost all platforms: float-to-string and string-to-float
2360 conversions within Python are now correctly rounded. Places these conversions
2361 occur include: str for floats and complex numbers; the float and complex
2362 constructors; old-style and new-style numeric formatting; serialization and
2363 deserialization of floats and complex numbers using marshal, pickle and json;
2364 parsing of float and imaginary literals in Python code; Decimal-to-float
2365 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002366
Georg Brandlba83f822010-03-14 09:50:54 +00002367 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2368 providing correctly-rounded strtod and dtoa C functions. This code is
2369 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2370 the C compiler. There may be a small number of platforms on which correct
2371 operation of this code cannot be guaranteed, so the code is not used: notably,
2372 this applies to platforms where the C double format is not IEEE 754 binary64,
2373 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2374 and Python's configure script is unable to determine how to change the FPU
2375 precision. On these platforms conversions use the platform strtod and dtoa,
2376 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002377
Georg Brandlba83f822010-03-14 09:50:54 +00002378- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2379 uses the correctly-rounded string <-> float conversions described above (when
2380 available), and so produces correctly rounded results that will display nicely
2381 under the float repr. There are two related small changes: (1) round now
2382 accepts any class with an ``__index__()`` method for its second argument (but
2383 no longer accepts floats for the second argument), and (2) an excessively
2384 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

2612 internal representation of integers, for performance reasons. Base 2**30 is
2613 enabled by default on 64-bit machines. Add --enable-big-digits option to
2614 configure, which overrides the default. Add sys.long_info structseq to
2615 provide information about the internal format.

2735
Georg Brandlba83f822010-03-14 09:50:54 +00002736- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2737 file objects with closefd=False. The file descriptor is still kept open but
2738 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00002762- On windows, ``os.chdir()`` given unicode was not working if
2763 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2764 this code path is really executed because I cannot move to such directory on
2765 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002767- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2768 element is temporarily replaced with an equivalent frozenset. But the
2769 eventual KeyError would always report the empty ``frozenset()`` as the missing

2791 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2792 step. This avoids problems with counting UTF-8 bytes that ignores the effect

2794
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002795- Issue #3739: The unicode-internal encoder now reports the number of characters

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004168- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4169 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4170 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4171 ``printf`` function, whereas PyString_FromFormat has an independent
4172 implementation and uses "%zd" on all platforms for size_t values.
4173 This makes a difference on win64, where ``printf`` needs "%Id" to display
4174 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00004194 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

4197 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4198 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004269 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4270 for catch_warnings() also led to an improvement in the raising of a
4271 DeprecationWarning related to warnings.warn_explicit().
4272
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004273- The deprecation warnings for the old camelCase threading API were removed.

4294 _check_logger_class from multiprocessing.
4295
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004296- Issue #2975: When compiling several extension modules with Visual Studio 2008
4297 from the same python interpreter, some environment variables would grow
4298 without limit.
4299
Benjamin Peterson37346b22008-08-23 20:27:43 +00004300- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4301 exploitation of poor argument checking.
4302
Gerhard Häringef2276b2008-09-12 13:54:06 +00004303- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4304
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004305- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4306 remaining ones have "pysqlite_" prefix.
4307

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004337What's New in Python 2.6 beta 3?
4338================================
4339
Barry Warsaw07a4a382008-08-21 01:15:08 +00004340*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004341
4342Core and Builtins
4343-----------------
4344
Guido van Rossumf8402962008-08-20 15:01:50 +00004345- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4346 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4347 extensions do not automatically benefit from the class attribute
4348 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4349 to their tp_flags field if they care. This is a backwards
4350 compatibility feature; in 3.0, all types will use the cache by
4351 default.
4352
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004353- Keyword arguments can now follow starred arguments. (``f(a, *args,
4354 keyword=23)`` is now valid syntax.)
4355
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004356- ctypes function pointers that are COM methods have a boolean True
4357 value again.
4358
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004359- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4360 by denying s# to parse objects that have a releasebuffer procedure,
4361 and introducing s*.
4362
Georg Brandl1e13ea92008-08-11 09:07:59 +00004363- Issue #3537: Fix an assertion failure when an empty but presized dict
4364 object was stored in the freelist.
4365
Mark Dickinsonb6467572008-08-04 21:30:09 +00004366- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4367 ValueError consistently across platforms.
4368
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004369- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4370 (64bit Unix, for example), unichr() would truncate its argument and return
4371 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4372
Neal Norwitze7d8be82008-07-31 17:17:14 +00004373- Apply security patches from Apple.
4374
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004375- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4376 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4377
Antoine Pitrou92f82162008-07-25 22:22:08 +00004378- Issue #1819: function calls with several named parameters are now on
4379 average 35% faster (as measured by pybench).
4380
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004381- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4382 the python debugger steps into a class statement: the free variables (local
4383 variables defined in an outer scope) would be deleted from the outer scope.
4384
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004385- Issue #2620: Overflow checking when allocating or reallocating memory
4386 was not always being done properly in some python types and extension
4387 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4388 all been updated to perform better checks and places in the code that
4389 would previously leak memory on the error path when such an allocation
4390 failed have been fixed.
4391
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004392Library
4393-------
4394
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004395- Issue #3612: Added some missing basic types in ctypes.wintypes.
4396
Benjamin Petersone977ad42008-08-20 01:42:01 +00004397- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4398 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4399
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004400- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4401 version reported by these tools does not necessarily follow the python
4402 version numbering scheme, so the module is less strict when parsing it.
4403
Nick Coghlanf70385a2008-08-18 12:42:46 +00004404- Issue #2235: Added Py3k warnings for types which will become unhashable
4405 under the stricter __hash__ inheritance rules in 3.0. Several types
4406 which did not meet the rules for hash invariants and were already
4407 unhashable in 3.0 have now been explicitly flagged as unhashable in
4408 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4409 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4410
Brett Cannon88f801d2008-08-18 00:46:22 +00004411- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4412 imported into the module but exposed as part of the module's API.
4413
Brett Cannon7b96f072008-08-18 00:41:11 +00004414- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4415
Brett Cannon46225e72008-08-18 00:36:52 +00004416- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004418- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4419
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004420- Issue #3575: Incremental decoder's decode function now takes bytearray
4421 by using 's*' instead of 't#'.
4422
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004423- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004424 fails unicode conversion on 2nd parameter. (windows only)
4425
Georg Brandl222e2082010-08-01 22:27:39 +00004426- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004427 in a redirect.
4428
Brett Cannonabe423e2008-08-16 21:47:07 +00004429- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004430 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004431
Facundo Batistaeb90b782008-08-16 14:44:07 +00004432- Issue #2776: fixed small issue when handling an URL with double slash
4433 after a 302 response in the case of not going through a proxy.
4434
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004435- Issue #2676: in the email package, content-type parsing was hanging on
4436 pathological input because of quadratic or exponential behaviour of a
4437 regular expression.
4438
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004439- Issue #3476: binary buffered reading through the new "io" library is now
4440 thread-safe.
4441
Brett Cannonbf3157b2008-08-14 05:00:03 +00004442- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4443 since mimetools itself is deprecated. Because modules are cached, all
4444 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4445
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004446- Issue #3134: shutil referenced undefined WindowsError symbol.
4447
Robert Schuppenies14646332008-08-10 11:01:53 +00004448- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4449 menu entries were not deleted.
4450
Brett Cannon83e81842008-08-09 23:30:55 +00004451- Copied the implementation of reduce() to _functools.reduce() to have a
4452 version that did not raise a DeprecationWarning under -3.
4453
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004454- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4455 a MemoryError rather than silently stop the iteration.
4456
Guido van Rossum59ce9012008-08-09 14:55:34 +00004457- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4458 to _sre.compile() will now be rejected. This should not affect anybody
4459 since the re.compile() function never generates invalid re-bytecode.
4460
Skip Montanaroa032bf42008-08-08 22:52:51 +00004461- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4462 upon first access it can be automatically initialized from the csv file if
4463 it wasn't initialized during instantiation.
4464
Brett Cannon3aa2a492008-08-06 22:28:09 +00004465- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4466 the reload() built-in has been removed.
4467
Brett Cannon7e30b672008-08-04 21:52:25 +00004468- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004469 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004480 asking for a specific length. This problem only affected files opened
4481 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004482

4527 regarding lack of coverage of new-style classes have also been
4528 removed, since the coverage is now fairly reasonable.

4537-----------------
4538
Georg Brandl3e483f62008-07-16 22:57:41 +00004539- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4540 its methods now allow for items objects that can be converted to
4541 an integer using operator.index().
4542
Mark Dickinson64b7e502008-07-16 09:40:03 +00004543- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4544 produced a ValueError instead of giving the correct float.
4545
Eric Smitha5fa5a22008-07-16 00:11:49 +00004546- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4547 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4548
Mark Dickinson7103aa42008-07-15 19:08:33 +00004549- Issue #3008: the float type has a new instance method 'float.hex'
4550 and a new class method 'float.fromhex' to convert floating-point
4551 numbers to and from hexadecimal strings, respectively.
4552
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004553- Issue #2235: __hash__ is once again inherited by default. To allow
4554 collections.Hashable to remain meaningful in the presence of the
4555 default hash implementation (object.__hash__), it is now possible
4556 to explicit block inheritance of hash by setting __hash__=None at
4557 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4558 level.
4559
Nick Coghlanb028f502008-07-13 14:52:36 +00004560- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4561 the parent module cannot be found while performing an absolute import.
4562 This means that an incorrectly defined __package__ attribute will
4563 now only prevent relative imports in that module rather than causing
4564 all imports from that module to fail.
4565
Nick Coghlan14ff9942008-07-08 14:21:42 +00004566- Issue #2517: Allow unicode messages in Exceptions again by correctly
4567 bypassing the instance dictionary when looking up __unicode__ on
4568 new-style classes.
4569
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004570- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4571 set to a custom object whose write() method happens to install
4572 another file in sys.stdout.
4573
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004574- Issue #3088: Corrected a race condition in classes derived from
4575 threading.local: the first member set by a thread could be saved in
4576 another thread's dictionary.
4577
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004578- Issue #3004: Minor change to slice.indices(): the start and stop
4579 arguments are now treated identically, making the behaviour easier
4580 to describe and understand. For example, slice(None, -10,
4581 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4582 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4583 10, -1).
4584
Georg Brandl278fc502008-07-19 12:46:12 +00004585- Issue #3219: Calling a function with repeated keyword arguments,
4586 f(a=2, a=23), would not cause a syntax error. This was a regression
4587 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004588
Georg Brandl278fc502008-07-19 12:46:12 +00004589- Issue #2862: Make int and float freelist management consistent with
4590 other freelists. Changes their CompactFreeList apis into
4591 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004592

4594-------
4595
Thomas Heller57adf222008-08-14 19:10:48 +00004596- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4597 api functions without holding the GIL, which could lead to a fatal
4598 error when they failed.
4599
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004600- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
4601

Jesse Noller13e9d582008-07-16 14:32:36 +00004608- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4609 ForkingPickler.register() to resolve conflict with ctypes.
4610
Vinay Sajip51e65192008-07-18 09:01:10 +00004611- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004612
Thomas Heller880f5292008-07-15 19:39:38 +00004613- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4614 a valid dlerror() message.
4615
Thomas Heller2bad6572008-07-15 17:19:50 +00004616- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4617 incomplete structure was created.
4618
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004619- Issue #3339: dummy_thread.acquire() should not return None.
4620
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004621- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4622
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004623- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004624
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004625- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4626 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004627 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004628 content-length. The problem had been corrected in the 2.4 branch, but never
4629 merged into trunk.
4630
Georg Brandle78fbcc2008-07-05 10:13:36 +00004631- Issue #2663: add filtering capability to shutil.copytree().

4634
4635- Issue #1526: Allow more than 64k files to be added to Zip64 file.
4636
4637- Issue #1746: Correct handling of zipfile archive comments (previously
4638 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004639 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004640
Vinay Sajip51e65192008-07-18 09:01:10 +00004641- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004642 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004643
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004644- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4645 handling is now the same as that of other special attributes like __name__).
4646
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004647- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4648 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005099- Issue #1631171: Re-implement the 'warnings' module in C (the
5100 original Python code has been kept as backup). This will allow for
5101 using the 'warning's machinery in such places as the parser where
5102 use of pure Python code is not possible. Both the ``showarning()``
5103 and ``formatwarning()`` gain an optional 'line' argument which is
5104 not called by default for backwards-compatibility reasons. Setting
5105 ``warnings.showwarning()`` to an implementation that lacks support
5106 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005169- Issue #2550: The approach used by client/server code for obtaining
5170 ports to listen on in network-oriented tests has been refined in an
5171 effort to facilitate running multiple instances of the entire
5172 regression test suite in parallel without issue.
5173 test_support.bind_port() has been fixed such that it will always
5174 return a unique port -- which wasn't always the case with the
5175 previous implementation, especially if socket options had been set
5176 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5177 new implementation of bind_port() will actually raise an exception
5178 if it is passed an AF_INET/SOCK_STREAM socket with either the
5179 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5180 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5181 the socket it's been passed. This currently only applies to
5182 Windows. This option prevents any other sockets from binding to the
5183 host/port we've bound to, thus removing the possibility of the
5184 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5185 when a second SOCK_STREAM socket binds and accepts to a host/port
5186 that's already been bound by another socket. The optional preferred
5187 port parameter to bind_port() has been removed. Under no
5188 circumstances should tests be hard coding ports!
5189
5190 test_support.find_unused_port() has also been introduced, which will
5191 pass a temporary socket object to bind_port() in order to obtain an
5192 unused port. The temporary socket object is then closed and
5193 deleted, and the port is returned. This method should only be used
5194 for obtaining an unused port in order to pass to an external program
5195 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5196 a parameter to a server-oriented class that doesn't give you direct
5197 access to the underlying socket used.
5198
5199 Finally, test_support.HOST has been introduced, which should be used
5200 for the host argument of any relevant socket calls (i.e. bind and
5201 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005202
5203 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005204 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005205 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5206 test_asynchat and test_socket_ssl.
5207
Georg Brandl3ee81df2008-05-17 18:14:43 +00005208 It is now possible for multiple instances of the regression test
5209 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005488- Added the future_builtins module, which contains hex() and oct().
5489 These are the PEP 3127 version of these functions, designed to be
5490 compatible with the hex() and oct() builtins from Python 3.0. They
5491 differ slightly in their output formats from the existing, unchanged
5492 Python 2.6 builtins. The expected usage of the future_builtins
5493 module is:
5494 from future_builtins import hex, oct
5495
Eric Smith7ef40bf2008-02-20 23:34:22 +00005496- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5497 exponents for exponents with absolute value < 100. Follows C99
5498 standard. This is a change on Windows, which would use 3 digits.
5499 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5500 so that any alterations it does to the resulting string will be
5501 available in stringlib/formatter.h (for float.__format__).
5502
Eric Smith5a3c1352008-02-19 13:21:56 +00005503- Implemented PEP 3101, Advanced String Formatting. This adds a new
5504 builtin format(); a format() method for str and unicode; a
5505 __format__() method to object, str, unicode, int, long, float, and
5506 datetime; the class string.Formatter; and the C API
5507 PyObject_Format().
5508
Georg Brandl3ee81df2008-05-17 18:14:43 +00005509- Fixed several potential crashes, all caused by specially crafted
5510 __del__ methods exploiting objects in temporarily inconsistent
5511 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005512
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005513- Issue #2115: Important speedup in setting __slot__ attributes. Also

5521 in order to allow pymalloc to free more arenas. Python may give back
5522 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005523
Georg Brandl3ee81df2008-05-17 18:14:43 +00005524- Issue #2045: Fix an infinite recursion triggered when printing a
5525 subclass of collections.defaultdict, if its default_factory is set
5526 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005527
Christian Heimesf75dbef2008-02-08 00:11:31 +00005528- Fixed a minor memory leak in dictobject.c. The content of the free
5529 list was not freed on interpreter shutdown.
5530
Georg Brandl21e99f42010-03-07 15:23:59 +00005531- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00005533
Georg Brandl3ee81df2008-05-17 18:14:43 +00005534- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5535 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005536 to compact the internal free lists of pre-allocted ints and floats.
5537
Georg Brandl3ee81df2008-05-17 18:14:43 +00005538- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5539 calls. Python expected the return type int but the fork familie
5540 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005541

Georg Brandl3ee81df2008-05-17 18:14:43 +00005554- Patch #1473257: generator objects gain a gi_code attribute. This is
5555 the same object as the func_code attribute of the function that
5556 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005557
Georg Brandl3ee81df2008-05-17 18:14:43 +00005558- Issue #1920: "while 0" statements were completely removed by the
5559 compiler, even in the presence of an "else" clause, which is
5560 supposed to be run when the condition is false. Now the compiler
5561 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005562
Guido van Rossumeead05f2008-01-24 18:21:02 +00005563- A few crashers fixed: weakref_in_del.py (issue #1377858);

5570
Georg Brandl3ee81df2008-05-17 18:14:43 +00005571- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005572 several extension methods and modules do not work without unicode
5573 support.
5574

5577
Georg Brandl14404b62008-01-19 19:27:05 +00005578- Issue #1679: "0x" was taken as a valid integer literal.
5579
Georg Brandl6caad7d2008-01-26 14:19:22 +00005580- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005581 added.
5582
Christian Heimesc94e2b52008-01-14 04:13:37 +00005583- sys.float_info / PyFloat_GetInfo: The floating point information

5585
Georg Brandl3ee81df2008-05-17 18:14:43 +00005586- Patch #1816: Added sys.flags structseq. It exposes the status of
5587 most command line arguments and PYTHON* environment variables.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005605- Improve some exception messages when Windows fails to load an
5606 extension module. Now we get for example '%1 is not a valid Win32
5607 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005615 and INF. float("nan"), float("inf") and float("-inf") now work on
5616 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005618- Compiler now generates simpler and faster code for dictionary
5619 literals. The oparg for BUILD_MAP now indicates an estimated
5620 dictionary size. There is a new opcode, STORE_MAP, for adding
5621 entries to the dictionary.

5651 file can now be directly executed by passing their name to the
5652 interpreter. The directory/zipfile is automatically inserted as the
5653 first entry in sys.path.

5664
Georg Brandl21e99f42010-03-07 15:23:59 +00005665- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005666 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5667 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005668
Georg Brandl3ee81df2008-05-17 18:14:43 +00005669- Issue #1686386: Tuple's tp_repr did not take into account the
5670 possibility of having a self-referential tuple, which is possible
5671 from C code. Nor did object's tp_str consider that a type's tp_str
5672 could do something that could lead to an inifinite recursion.
5673 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5674 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005675
Georg Brandl3ee81df2008-05-17 18:14:43 +00005676- Issue #1164: It was possible to trigger deadlock when using the
5677 'print' statement to write to a file since the GIL was not released
5678 as needed. Now PyObject_Print() does the right thing along with
5679 various tp_print implementations of the built-in types and those in
5680 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005681
Georg Brandl3ee81df2008-05-17 18:14:43 +00005682- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00005689- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005690 PyObject_Call() never calling back out to Python code to trigger
5691 recursion depth updates/checks. Required the creation of a static
5692 RuntimeError instance in case normalizing an exception put the
5693 recursion check value past its limit. Fixes crashers
5694 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005709- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005710 __*__ attributes. (Some already existed, e.g., __doc__ and
5711 __name__.)

5717 calls.
5718
Collin Winter62903052007-05-18 23:11:24 +00005719- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005720 "except E as target:". This is to provide forwards compatibility
5721 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005728- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005729 setting a plain string, ie don't expand to single letter identifiers.
5730
Raymond Hettinger13936692007-04-11 18:40:58 +00005731- Request #1191699: Slices can now be pickled.
5732
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005733- Request #1193128: str.translate() now allows a None argument for
5734 translations that only remove characters without re-mapping the
5735 remaining characters.
5736
Georg Brandl5cb76c12007-03-21 09:00:39 +00005737- Patch #1682205: a TypeError while unpacking an iterable is no longer

5741
Guido van Rossum143b5642007-03-23 04:58:42 +00005742- Bug #1683368: The object.__init__() and object.__new__() methods are
5743 now stricter in rejecting excess arguments. The only time when
5744 either allows excess arguments is when it is not overridden and the
5745 other one is. For backwards compatibility, when both are
5746 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005747 warning later). Also, type.__init__() insists on the same signature
5748 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005749
Georg Brandl3ee81df2008-05-17 18:14:43 +00005750- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5751 object to complex using its __complex__() method before falling back
5752 to the __float__() method. Therefore, the functions in the cmath
5753 module now can operate on objects that define a __complex__()
5754 method.

5771
Georg Brandl7b9c5552007-03-12 14:30:05 +00005772- Bug #1678647: write a newline after printing an exception in any
5773 case, even when converting the value to a string failed.
5774
Georg Brandl871f1bc2007-03-12 13:17:36 +00005775- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005776 its argument, if it exists. If not, it will work like before. This
5777 allows customizing the output of dir() in the presence of a
5778 __getattr__().

5787 parthensized forms. This means complex(repr(x)) now works instead of
5788 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005789
Georg Brandlaa2321b2007-03-07 00:40:28 +00005790- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005791 makes the filenames the warning module prints much more sensible
5792 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005805- Patch #1674228: when assigning a slice (old-style), check for the
5806 sq_ass_slice instead of the sq_slice slot.
5807
Georg Brandl3ee81df2008-05-17 18:14:43 +00005808- When printing an unraisable error, don't print exceptions. before

Georg Brandl92a6bae2007-03-13 17:43:32 +00006377- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006378 are set for invalid interpolation sequences that would lead to
6379 errors on reading back those values.

6435 TestCase and TestSuite subclasses (not instances) are no longer
6436 accepted in TestSuite.addTest(). This should cause no
6437 incompatibility since it never made sense with ordinary subclasses
6438 -- the failure just occurred later, with a more cumbersome
6439 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006726 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00006828 time so that opening a database previously created with the DB_DUP
6829 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6830 opens. Specifically: dictionary assignment to a DB object will
6831 replace all values for a given key when the database allows
6832 duplicate values. DB users should use DB.put(k, v) when they want
6833 to store duplicates; not DB[k] = v.

7189 of w# format code incorrectly truncated the length to an int, even
7190 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7191 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007221- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7222 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007223
