13-----------------
14
Antoine Pitrou0a7b65b2010-09-08 12:40:49 +000015- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
16 thread-local storage key.
17
Victor Stinnercaafd772010-09-08 10:51:01 +000018- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
19 encoding and errors attributes instead of using utf-8 in strict mode, to get
20 the same behaviour than the print statement.
21
Antoine Pitrou9cf85f12010-09-01 21:17:34 +000022- Issue #9737: Fix a crash when trying to delete a slice or an item from
23 a memoryview object.
24
Martin v. Löwis6086b0d2010-08-19 09:09:04 +000025- Restore GIL in nis_cat in case of error.
26
Benjamin Peterson6f3d6a92010-08-25 23:17:42 +000027- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
28
Florent Xicluna172e15f2010-08-09 20:02:00 +000029- Issue #8530: Prevent stringlib fastsearch from reading beyond the front
30 of an array.
31
Raymond Hettinger3ad323e2010-08-06 10:18:56 +000032- Issue #83755: Implicit set-to-frozenset conversion was not thread-safe.
33
Mark Dickinsonaad57bd2010-08-01 10:45:15 +000034- Issue #9416: Fix some issues with complex formatting where the
35 output with no type specifier failed to match the str output:
36
37 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
38 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
39
Antoine Pitrou32669782010-07-11 12:14:05 +000040- Issue #7616: Fix copying of overlapping memoryview slices with the Intel

45
Victor Stinner46287f52010-09-13 20:31:34 +000046- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X
47 (macpath module).
48
Antoine Pitroue4195e82010-09-12 14:56:27 +000049- Issue #9837: The read() method of ZipExtFile objects (as returned by
50 ZipFile.open()) could return more bytes than requested.
51
Raymond Hettinger20397532010-09-12 02:11:45 +000052- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
53 This prevents user-created self-referencing ordered dictionaries from
54 becoming permanently uncollectable GC garbage. The downside is that
55 removing __del__ means that the internal doubly-linked list has to wait for
56 GC collection rather than freeing memory immediately when the refcnt drops
57 to zero.
58
Raymond Hettingerffd2a422010-09-10 10:47:22 +000059- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
60 different internal state for small values of n. Fixed by salting the
61 value.
62
Antoine Pitrouc818ed42010-09-07 21:40:25 +000063- Issue #9792: In case of connection failure, socket.create_connection()
64 would swallow the exception and raise a new one, making it impossible
65 to fetch the original errno, or to filter timeout errors. Now the
66 original error is re-raised.
67
Antoine Pitrouf4f61712010-09-07 16:34:47 +000068- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
69 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
70 be updated back after the system call. Original patch by Brian Brazil.
71
Antoine Pitroudca9de92010-09-04 17:52:26 +000072- Issue #1100562: Fix deep-copying of objects derived from the list and
73 dict types. Patch by Michele Orrù and Björn Lindqvist.
74
Fred Drakea1e627d2010-09-03 03:55:50 +000075- Issue #7005: Fixed output of None values for RawConfigParser.write and
76 ConfigParser.write.
77
Daniel Stutzbach66c981b2010-08-31 20:29:39 +000078- Issue #808164: Fixed socket.close to avoid references to globals, to
79 avoid issues when socket.close is called from a __del__ method.
80
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +000081- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
82 falling into recursion.
83
R. David Murray7c4bf552010-08-25 01:45:57 +000084- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
85 character years even if the message contains RFC822 two character years.
86
Daniel Stutzbach91287322010-08-24 21:09:30 +000087- Issue #8750: Fixed MutableSet's methods to correctly handle
88 reflexive operations, namely x -= x and x ^= x.
89
Victor Stinnercaafd772010-09-08 10:51:01 +000090- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +000091 error handling when accepting a new connection.
92
Giampaolo Rodolà63308d72010-08-23 21:58:47 +000093- Issue #658749: asyncore's connect() method now correctly interprets winsock
94 errors.
95
Vinay Sajip1ddd51f2010-08-23 17:50:30 +000096- Issue #9501: Fixed logging regressions in cleanup code.

99 module now correctly return a set. (Patch by Eli Bendersky.)
100

102 ignored by the buffered IO layer anymore.
103
Benjamin Peterson52c36052010-08-21 03:03:22 +0000104- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
105 are not held onto after they are deleted elsewhere.
106
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000107- Issue #9626: the view methods for collections.OrderedDict() were returning
108 the unordered versions inherited from dict. Those methods are now
109 overridden to provide ordered views.
110
Éric Araujo0389ae62010-08-14 03:07:46 +0000111- Issue #8688: MANIFEST files created by distutils now include a magic
112 comment indicating they are generated. Manually maintained MANIFESTs
113 without this marker will not be overwritten or removed.
114
Antoine Pitroue1436d12010-08-12 15:25:51 +0000115- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
116 and a BadZipfile error is raised if it doesn't match (as used to be the
117 case in Python 2.5 and earlier).
118
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000119- Issue #9550: a BufferedReader could issue an additional read when the
120 original read request had been satisfied, which could block indefinitely

122 patch by Jason V. Miller.
123
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000124- Issue #9551: Don't raise TypeError when setting the value to None for

128 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
129
Antoine Pitrou99009162010-08-09 22:51:24 +0000130- Issue #3757: thread-local objects now support cyclic garbage collection.
131 Thread-local objects involved in reference cycles will be deallocated
132 timely by the cyclic GC, even if the underlying thread is still running.
133
Florent Xicluna2f1b1ff2010-08-09 20:46:49 +0000134- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the

143 This is how it is supposed to work, wget and curl do the same. Previous
144 behavior was wrong.
145

478 start byte and the continuation byte(s) are now considered invalid, instead
479 of the number of bytes specified by the start byte.
480 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
481 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

492 objects. (1) The comparison could incorrectly return True in some cases
493 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Brett Cannon5fb89df2010-05-05 20:54:53 +0000634
Georg Brandlfee0f442010-05-22 21:26:21 +0000635- Issue #1533: Fix inconsistency in range function argument processing: any
636 non-float non-integer argument is now converted to an integer (if possible)
637 using its __int__ method. Previously, only small arguments were treated this
638 way; larger arguments (those whose __int__ was outside the range of a C long)
639 would produce a TypeError.
Mark Dickinsona8d26682010-05-04 16:18:25 +0000640
Georg Brandlfee0f442010-05-22 21:26:21 +0000641- Issue #8202: ``sys.argv[0]`` is now set to '-m' instead of '-c' when searching

Georg Brandlfee0f442010-05-22 21:26:21 +0000647 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +0000648 benefit compared to the dynamic memory allocation fallback. Patch by
649 Charles-François Natali.
650

659 on MacOS X. That is, ``python setup.py install --user`` will install into
660 ``~/Library/Python/2.7`` instead of ``~/.local``.

Georg Brandlfee0f442010-05-22 21:26:21 +0000665- Issue #8681: Make the zlib module's error messages more informative when the
666 zlib itself doesn't give any detailed explanation.

Georg Brandlfee0f442010-05-22 21:26:21 +0000673- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
674 messages when accessing undefined class attributes because of the cheap
675 inheritance with the underlying socket object. The cheap inheritance has been
676 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +0000677
Georg Brandlfee0f442010-05-22 21:26:21 +0000678- Issue #4265: ``shutil.copyfile()`` was leaking file descriptors when disk

Georg Brandlfee0f442010-05-22 21:26:21 +0000689- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
690 operation raises multiple signals and more than one of those signals is
691 trapped, the specification determines the order in which the signals should be
692 handled. In many cases this order wasn't being followed, leading to the wrong
693 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +0000694
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +0000695- Issue #7865: The close() method of :mod:`io` objects should not swallow
Georg Brandlfee0f442010-05-22 21:26:21 +0000696 exceptions raised by the implicit flush(). Also ensure that calling close()

860Core and Builtins
861-----------------
862
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000863- Issue #7301: Add environment variable $PYTHONWARNINGS.
864
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000865- Issue #8329: Don't return the same lists from select.select when no fds are
866 changed.
867
Georg Brandlfee0f442010-05-22 21:26:21 +0000868- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000869 on 64-bit machines. The shift count for either left or right shift is
870 permitted to be up to sys.maxsize.
871
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000872- Ensure that tokenization of identifiers is not affected by locale.
873
Georg Brandlfee0f442010-05-22 21:26:21 +0000874- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000875
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000876- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
877
Georg Brandlfee0f442010-05-22 21:26:21 +0000878- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
879 with a non-empty format string. This is an effort to future-proof user
880 code. If a derived class does not currently implement __format__ but later
881 adds its own __format__, it would most likely break user code that had
882 supplied a format string. This will be changed to a DeprecationWaring in
883 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000884
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000885- Issue #8268: Old-style classes (not just instances) now support weak
886 references.
887
Georg Brandlfee0f442010-05-22 21:26:21 +0000888- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
889 is set.

Victor Stinnerc7790ed2010-03-22 12:36:28 +0000891- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +0000892
Benjamin Peterson96545892010-03-21 20:21:00 +0000893- Issue #6474: Make error message from passing an inadequate number of keyword
894 arguments to a function correct.
895
Benjamin Peterson0dee9c12010-03-17 20:41:42 +0000896- Issue #8164: Don't allow lambda functions to have a docstring.

Victor Stinner66644262010-03-10 22:30:19 +0000898- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +0000899 (SIGINT). If an error occurs while importing the site module, the error is
900 printed and Python exits. Initialize the GIL before importing the site

909
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000910- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000911 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
912 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000913

Georg Brandlfee0f442010-05-22 21:26:21 +0000916- Issue #8257: The Decimal construct now accepts a float instance directly,
917 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000918
919 >>> Decimal(1.1)
920 Decimal('1.100000000000000088817841970012523233890533447265625')
921
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000922- collections.Counter() now supports a subtract() method.
923
Georg Brandlfee0f442010-05-22 21:26:21 +0000924- The functools module now has a total_ordering() class decorator to simplify
925 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000926
Georg Brandlfee0f442010-05-22 21:26:21 +0000927- The functools module also adds cmp_to_key() as a tool to transition old-style
928 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000929
Georg Brandlfee0f442010-05-22 21:26:21 +0000930- Issue #8294: The Fraction constructor now accepts Decimal and float instances
931 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000932
Georg Brandlfee0f442010-05-22 21:26:21 +0000933- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
934 InvalidOperation instead of returning False. (Comparisons involving a quiet
935 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
936 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000937
Georg Brandlfee0f442010-05-22 21:26:21 +0000938- Issue #2531: Comparison operations between floats and Decimal instances now
939 return a result based on the numeric values of the operands; previously they
940 returned an arbitrary result based on the relative ordering of id(float) and
941 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000942
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000943- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000944 argument `-` which tells it to read files to compile from stdin. Each line is
945 read on demand and the named file is compiled immediately. (Original patch by
946 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000947
Georg Brandlfee0f442010-05-22 21:26:21 +0000948- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000951- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
952 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000953 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000954
Georg Brandlfee0f442010-05-22 21:26:21 +0000955- Comparisons using one of <, <=, >, >= between a complex instance and a
956 Fractions instance now raise TypeError instead of returning True/False. This
957 makes Fraction <=> complex comparisons consistent with int <=> complex, float
958 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000959

968
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000969- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000970 didn't support chflags() (for example ZFS under FreeBSD). The error is now
971 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000972
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000973- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
974 deprecated.
975
Georg Brandlfee0f442010-05-22 21:26:21 +0000976- Issue #7860: platform.uname now reports the correct 'machine' type when Python
977 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +0000978

Victor Stinner75227342010-03-12 14:30:26 +00001012
Vinay Sajipecfa08f2010-03-12 09:16:10 +00001013- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001014 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1015 log file to compute the next rollover time. If the log file does not exist,
1016 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001017
Georg Brandlba83f822010-03-14 09:50:54 +00001018- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001026- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1027 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1028 This is a behavior change, so email's minor version number is now bumped, to
1029 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00001030

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001057- Issue #8300: When passing a non-integer argument to struct.pack with any
1058 integer format code, struct.pack first attempts to convert the non-integer
1059 using its __index__ method. If that method is non-existent or raises
1060 TypeError it goes on to try the __int__ method, as described below.
1061
Georg Brandlba83f822010-03-14 09:50:54 +00001062- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1063 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1064 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001065 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1066 inconsistent: __int__ was used for some integer codes but not for others, and
1067 the set of integer codes for which it was used differed between native packing
1068 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001372 file position when calling `truncate()`. It would previously change the file
1373 position to the given argument, which goes against the tradition of

1380 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1469-----------------
1470
Georg Brandlba83f822010-03-14 09:50:54 +00001471- The ``__complex__()`` method is now looked up on the class of instances to
1472 make it consistent with other special methods.

1476
Mark Dickinson1b34d252010-01-01 17:27:30 +00001477- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001478 DeprecationWarning when passed a float argument where an integer was expected.
1479 These functions and methods now raise TypeError instead. The majority of the
1480 effects of this change are in the extension modules, but some core functions
1481 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1482 and many unicode/str methods.

1496 of integers: the result of a/b is now correctly rounded for ints a and b (at
1497 least on IEEE 754 platforms), and in particular does not depend on the
1498 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001505 executables on OSX.
1506
Georg Brandlba83f822010-03-14 09:50:54 +00001507 These executables now work properly with the arch(1) command: ``arch -ppc
1508 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001665- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1666 decimal string that's guaranteed to round back to x under correct rounding
1667 (with round-half-to-even rounding mode). Previously it gave a string based on
1668 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1669 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1670 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001671
Georg Brandlba83f822010-03-14 09:50:54 +00001672- Issue #7117: On almost all platforms: float-to-string and string-to-float
1673 conversions within Python are now correctly rounded. Places these conversions
1674 occur include: str for floats and complex numbers; the float and complex
1675 constructors; old-style and new-style numeric formatting; serialization and
1676 deserialization of floats and complex numbers using marshal, pickle and json;
1677 parsing of float and imaginary literals in Python code; Decimal-to-float
1678 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001679
Georg Brandlba83f822010-03-14 09:50:54 +00001680 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1681 providing correctly-rounded strtod and dtoa C functions. This code is
1682 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1683 the C compiler. There may be a small number of platforms on which correct
1684 operation of this code cannot be guaranteed, so the code is not used: notably,
1685 this applies to platforms where the C double format is not IEEE 754 binary64,
1686 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1687 and Python's configure script is unable to determine how to change the FPU
1688 precision. On these platforms conversions use the platform strtod and dtoa,
1689 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001691- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1692 uses the correctly-rounded string <-> float conversions described above (when
1693 available), and so produces correctly rounded results that will display nicely
1694 under the float repr. There are two related small changes: (1) round now
1695 accepts any class with an ``__index__()`` method for its second argument (but
1696 no longer accepts floats for the second argument), and (2) an excessively
1697 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1698 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001841 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1842 (2) parsing of strings representing infinities and nans was locale aware; and
1843 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001845- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1846 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1847 but with at least one decimal point and with a default precision
1848 of 12. Previously, the behavior the same but with a default precision of 6.
1849 This more closely matches ``str()``, and reduces surprises when adding
1850 alignment flags to the empty presentation type. This also affects the new
1851 complex.__format__ in the same way.
1852
1853- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00002034- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2035 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2036 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002039- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2048
Georg Brandlba83f822010-03-14 09:50:54 +00002049- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2050 file objects with closefd=False. The file descriptor is still kept open but
2051 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00002075- On windows, ``os.chdir()`` given unicode was not working if

2077 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00002080- Issue #4069: When ``set.remove(element)`` is used with a set element, the

2082 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00002103- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2104 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2105 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2106 of using the replace error handler in PyUnicode_DecodeUTF8().
2107
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002108- Issue #3739: The unicode-internal encoder now reports the number of characters

2110
Georg Brandlba83f822010-03-14 09:50:54 +00002111- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2113 gives improved memory leak detection when running under Valgrind, while taking
2114 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003479- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3480
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003481- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3482 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3483 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3484 ``printf`` function, whereas PyString_FromFormat has an independent
3485 implementation and uses "%zd" on all platforms for size_t values.
3486 This makes a difference on win64, where ``printf`` needs "%Id" to display
3487 64bit values.
3488
Benjamin Peterson97179b02008-09-09 20:55:01 +00003489- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3493 object; previously an int would be returned for small values. the __long__
3494 method is allowed to return either an int or a long, but the behaviour of
3495 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003497- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003504 was correctly parsed but parsing of subsequent arguments failed.
3505
Vinay Sajip35e3b032008-09-01 14:33:59 +00003506- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003507 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3508 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3509 when given a tuple of classes as second argument, were looking up
3510 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3511 type object.
3512

3656-----------------
3657
Guido van Rossumf8402962008-08-20 15:01:50 +00003658- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3659 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3660 extensions do not automatically benefit from the class attribute
3661 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3662 to their tp_flags field if they care. This is a backwards
3663 compatibility feature; in 3.0, all types will use the cache by
3664 default.
3665
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003666- Keyword arguments can now follow starred arguments. (``f(a, *args,

3668
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003669- ctypes function pointers that are COM methods have a boolean True
3670 value again.

3681
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003682- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3683 (64bit Unix, for example), unichr() would truncate its argument and return
3684 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

3693
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003694- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3695 the python debugger steps into a class statement: the free variables (local

Gregory P. Smith0470bab2008-07-22 04:46:32 +00003698- Issue #2620: Overflow checking when allocating or reallocating memory
3699 was not always being done properly in some python types and extension
3700 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3701 all been updated to perform better checks and places in the code that
3702 would previously leak memory on the error path when such an allocation
3703 failed have been fixed.

3709
Benjamin Petersone977ad42008-08-20 01:42:01 +00003710- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3711 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3712
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003713- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3714 version reported by these tools does not necessarily follow the python
3715 version numbering scheme, so the module is less strict when parsing it.
3716
Nick Coghlanf70385a2008-08-18 12:42:46 +00003717- Issue #2235: Added Py3k warnings for types which will become unhashable
3718 under the stricter __hash__ inheritance rules in 3.0. Several types
3719 which did not meet the rules for hash invariants and were already
3720 unhashable in 3.0 have now been explicitly flagged as unhashable in
3721 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3722 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3723
Brett Cannon88f801d2008-08-18 00:46:22 +00003724- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3756 since mimetools itself is deprecated. Because modules are cached, all
3757 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3758

3768 a MemoryError rather than silently stop the iteration.
3769
Guido van Rossum59ce9012008-08-09 14:55:34 +00003770- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3771 to _sre.compile() will now be rejected. This should not affect anybody
3772 since the re.compile() function never generates invalid re-bytecode.
3773
Skip Montanaroa032bf42008-08-08 22:52:51 +00003774- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3775 upon first access it can be automatically initialized from the csv file if
3776 it wasn't initialized during instantiation.
3777
Brett Cannon3aa2a492008-08-06 22:28:09 +00003778- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3779 the reload() built-in has been removed.
3780
Brett Cannon7e30b672008-08-04 21:52:25 +00003781- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003782 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3790 raised an AttributeError.
3791

Antoine Pitroude781a42008-08-09 12:43:23 +00003793 asking for a specific length. This problem only affected files opened
3794 using the new "io" module, not the built-in open() function.

3820 file name rather than a ZipInfo instance, so files are extracted with
3821 mode 0600 rather than 000 under Unix.
3822
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003823- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3824 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003835- Issue #2235: the C API function PyObject_HashNotImplemented and its
3836 interaction with the tp_hash slot (added in 2.6b2) are now documented
3837
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003838- Issue #643841: The language reference now provides more detailed
3839 coverage of the lookup process for special methods. The disclaimers
3840 regarding lack of coverage of new-style classes have also been
3841 removed, since the coverage is now fairly reasonable.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003847*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003849Core and Builtins
3850-----------------
3851
Georg Brandl3e483f62008-07-16 22:57:41 +00003852- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3853 its methods now allow for items objects that can be converted to
3854 an integer using operator.index().
3855
Mark Dickinson64b7e502008-07-16 09:40:03 +00003856- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3857 produced a ValueError instead of giving the correct float.
3858
Eric Smitha5fa5a22008-07-16 00:11:49 +00003859- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3860 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3861
Mark Dickinson7103aa42008-07-15 19:08:33 +00003862- Issue #3008: the float type has a new instance method 'float.hex'
3863 and a new class method 'float.fromhex' to convert floating-point
3864 numbers to and from hexadecimal strings, respectively.
3865
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003866- Issue #2235: __hash__ is once again inherited by default. To allow
3867 collections.Hashable to remain meaningful in the presence of the
3868 default hash implementation (object.__hash__), it is now possible
3869 to explicit block inheritance of hash by setting __hash__=None at
3870 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3871 level.
3872
Nick Coghlanb028f502008-07-13 14:52:36 +00003873- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3874 the parent module cannot be found while performing an absolute import.
3875 This means that an incorrectly defined __package__ attribute will
3876 now only prevent relative imports in that module rather than causing
3877 all imports from that module to fail.
3878
Nick Coghlan14ff9942008-07-08 14:21:42 +00003879- Issue #2517: Allow unicode messages in Exceptions again by correctly
3880 bypassing the instance dictionary when looking up __unicode__ on
3881 new-style classes.
3882
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003883- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3884 set to a custom object whose write() method happens to install
3885 another file in sys.stdout.
3886
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003887- Issue #3088: Corrected a race condition in classes derived from
3888 threading.local: the first member set by a thread could be saved in
3889 another thread's dictionary.
3890
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003891- Issue #3004: Minor change to slice.indices(): the start and stop
3892 arguments are now treated identically, making the behaviour easier
3893 to describe and understand. For example, slice(None, -10,
3894 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3895 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3896 10, -1).
3897
Georg Brandl278fc502008-07-19 12:46:12 +00003898- Issue #3219: Calling a function with repeated keyword arguments,
3899 f(a=2, a=23), would not cause a syntax error. This was a regression
3900 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003901
Georg Brandl278fc502008-07-19 12:46:12 +00003902- Issue #2862: Make int and float freelist management consistent with
3903 other freelists. Changes their CompactFreeList apis into
3904 ClearFreeList apis and calls them via gc.collect().

3910 api functions without holding the GIL, which could lead to a fatal
3911 error when they failed.
3912
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003913- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003921- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3922 ForkingPickler.register() to resolve conflict with ctypes.
3923
Vinay Sajip51e65192008-07-18 09:01:10 +00003924- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003926- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3927 a valid dlerror() message.
3928
Thomas Heller2bad6572008-07-15 17:19:50 +00003929- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3930 incomplete structure was created.
3931

3935
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003936- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003937
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003938- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3939 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003940 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003941 content-length. The problem had been corrected in the 2.4 branch, but never
3942 merged into trunk.
3943
Georg Brandle78fbcc2008-07-05 10:13:36 +00003944- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003955 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003956
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003957- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3958 handling is now the same as that of other special attributes like __name__).
3959
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003960- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3961 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004350 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004351
4352 This is controlled by the configure argument ``--with-universal-archs``:
4353
4354 - ``--with-universal-archs=all``: install 4-way universal
4355
4356 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4357
4358 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4359
4360 This option should be used in combination with ``--enable-universalsdk=``.
4361
4362 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004412- Issue #1631171: Re-implement the 'warnings' module in C (the
4413 original Python code has been kept as backup). This will allow for
4414 using the 'warning's machinery in such places as the parser where
4415 use of pure Python code is not possible. Both the ``showarning()``
4416 and ``formatwarning()`` gain an optional 'line' argument which is
4417 not called by default for backwards-compatibility reasons. Setting
4418 ``warnings.showwarning()`` to an implementation that lacks support
4419 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004482- Issue #2550: The approach used by client/server code for obtaining
4483 ports to listen on in network-oriented tests has been refined in an
4484 effort to facilitate running multiple instances of the entire
4485 regression test suite in parallel without issue.
4486 test_support.bind_port() has been fixed such that it will always
4487 return a unique port -- which wasn't always the case with the
4488 previous implementation, especially if socket options had been set
4489 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4490 new implementation of bind_port() will actually raise an exception
4491 if it is passed an AF_INET/SOCK_STREAM socket with either the
4492 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4493 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4494 the socket it's been passed. This currently only applies to
4495 Windows. This option prevents any other sockets from binding to the
4496 host/port we've bound to, thus removing the possibility of the
4497 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4498 when a second SOCK_STREAM socket binds and accepts to a host/port
4499 that's already been bound by another socket. The optional preferred
4500 port parameter to bind_port() has been removed. Under no
4501 circumstances should tests be hard coding ports!
4502
4503 test_support.find_unused_port() has also been introduced, which will
4504 pass a temporary socket object to bind_port() in order to obtain an
4505 unused port. The temporary socket object is then closed and
4506 deleted, and the port is returned. This method should only be used
4507 for obtaining an unused port in order to pass to an external program
4508 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4509 a parameter to a server-oriented class that doesn't give you direct
4510 access to the underlying socket used.
4511
4512 Finally, test_support.HOST has been introduced, which should be used
4513 for the host argument of any relevant socket calls (i.e. bind and
4514 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004515
4516 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004517 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004518 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4519 test_asynchat and test_socket_ssl.
4520
Georg Brandl3ee81df2008-05-17 18:14:43 +00004521 It is now possible for multiple instances of the regression test
4522 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00004791- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004792 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004793
Georg Brandlad61bc82008-02-23 15:11:18 +00004794- Issue #2067: file.__exit__() now calls subclasses' close() method.
4795
4796- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004797
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004798- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00004799 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00004800
Eric Smitha73fbe72008-02-23 03:09:44 +00004801- Added the future_builtins module, which contains hex() and oct().
4802 These are the PEP 3127 version of these functions, designed to be
4803 compatible with the hex() and oct() builtins from Python 3.0. They
4804 differ slightly in their output formats from the existing, unchanged
4805 Python 2.6 builtins. The expected usage of the future_builtins
4806 module is:
4807 from future_builtins import hex, oct
4808
Eric Smith7ef40bf2008-02-20 23:34:22 +00004809- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4810 exponents for exponents with absolute value < 100. Follows C99
4811 standard. This is a change on Windows, which would use 3 digits.
4812 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4813 so that any alterations it does to the resulting string will be
4814 available in stringlib/formatter.h (for float.__format__).
4815
Eric Smith5a3c1352008-02-19 13:21:56 +00004816- Implemented PEP 3101, Advanced String Formatting. This adds a new
4817 builtin format(); a format() method for str and unicode; a
4818 __format__() method to object, str, unicode, int, long, float, and
4819 datetime; the class string.Formatter; and the C API
4820 PyObject_Format().
4821
Georg Brandl3ee81df2008-05-17 18:14:43 +00004822- Fixed several potential crashes, all caused by specially crafted
4823 __del__ methods exploiting objects in temporarily inconsistent
4824 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004825
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004826- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004827 prevent a possible crash: an Abstract Base Class would try to access
4828 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004829
Georg Brandl3ee81df2008-05-17 18:14:43 +00004830- Fixed repr() and str() of complex numbers with infinity or nan as
4831 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004833- Clear all free lists during a gc.collect() of the highest generation
4834 in order to allow pymalloc to free more arenas. Python may give back
4835 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004836
Georg Brandl3ee81df2008-05-17 18:14:43 +00004837- Issue #2045: Fix an infinite recursion triggered when printing a
4838 subclass of collections.defaultdict, if its default_factory is set
4839 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004840
Christian Heimesf75dbef2008-02-08 00:11:31 +00004841- Fixed a minor memory leak in dictobject.c. The content of the free
4842 list was not freed on interpreter shutdown.
4843
Georg Brandl21e99f42010-03-07 15:23:59 +00004844- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004845 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004846
Georg Brandl3ee81df2008-05-17 18:14:43 +00004847- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4848 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004849 to compact the internal free lists of pre-allocted ints and floats.
4850
Georg Brandl3ee81df2008-05-17 18:14:43 +00004851- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4852 calls. Python expected the return type int but the fork familie
4853 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004854
Georg Brandl3ee81df2008-05-17 18:14:43 +00004855- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4856 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004857
Georg Brandl3ee81df2008-05-17 18:14:43 +00004858- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4859 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004860
Georg Brandl3ee81df2008-05-17 18:14:43 +00004861- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4862 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004864- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4865 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004866
Georg Brandl3ee81df2008-05-17 18:14:43 +00004867- Patch #1473257: generator objects gain a gi_code attribute. This is
4868 the same object as the func_code attribute of the function that
4869 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004870
Georg Brandl3ee81df2008-05-17 18:14:43 +00004871- Issue #1920: "while 0" statements were completely removed by the
4872 compiler, even in the presence of an "else" clause, which is
4873 supposed to be run when the condition is false. Now the compiler
4874 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004875
Guido van Rossumeead05f2008-01-24 18:21:02 +00004876- A few crashers fixed: weakref_in_del.py (issue #1377858);
4877 loosing_dict_ref.py (issue #1303614, test67.py);
4878 borrowed_ref_[34].py (not in tracker).
4879
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004880- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004881 suppressed while an extension is loaded by calling SetErrorMode in
4882 dynload_win.c. The error is still reported properly.
4883
Georg Brandl3ee81df2008-05-17 18:14:43 +00004884- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004885 several extension methods and modules do not work without unicode
4886 support.
4887
Georg Brandl26543b12008-01-21 18:36:51 +00004888- Issue #1882: when compiling code from a string, encoding cookies in the
4889 second line of code were not always recognized correctly.
4890
Georg Brandl14404b62008-01-19 19:27:05 +00004891- Issue #1679: "0x" was taken as a valid integer literal.
4892
Georg Brandl6caad7d2008-01-26 14:19:22 +00004893- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004894 added.
4895
Christian Heimesc94e2b52008-01-14 04:13:37 +00004896- sys.float_info / PyFloat_GetInfo: The floating point information
4897 object was converted from a dict to a specialized structseq object.
4898
Georg Brandl3ee81df2008-05-17 18:14:43 +00004899- Patch #1816: Added sys.flags structseq. It exposes the status of
4900 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004901
Georg Brandl3ee81df2008-05-17 18:14:43 +00004902- Objects/structseq.c: Implemented new structseq representation. The
4903 patch makes structseqs (e.g. the return value of os.stat) more
4904 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004905
Georg Brandl3ee81df2008-05-17 18:14:43 +00004906- Patch #1700288: added a type attribute cache that caches method
4907 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004908
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004909- Bug #1776: __import__() no longer accepts filenames on any platform.

4913
Georg Brandl3ee81df2008-05-17 18:14:43 +00004914- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4915 envvar and sys.dont_write_bytecode attribute. All these can be set
4916 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004917
Georg Brandl3ee81df2008-05-17 18:14:43 +00004918- Improve some exception messages when Windows fails to load an
4919 extension module. Now we get for example '%1 is not a valid Win32
4920 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004921
Georg Brandl3ee81df2008-05-17 18:14:43 +00004922- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004924- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4925 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004926
Christian Heimes0a8143f2007-12-18 23:22:54 +00004927- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004928 and INF. float("nan"), float("inf") and float("-inf") now work on
4929 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004930
Georg Brandl3ee81df2008-05-17 18:14:43 +00004931- Compiler now generates simpler and faster code for dictionary
4932 literals. The oparg for BUILD_MAP now indicates an estimated
4933 dictionary size. There is a new opcode, STORE_MAP, for adding
4934 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004935

4964 file can now be directly executed by passing their name to the
4965 interpreter. The directory/zipfile is automatically inserted as the
4966 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004967
Georg Brandl3ee81df2008-05-17 18:14:43 +00004968- Issue #1265: Fix a problem with sys.settrace, if the tracing
4969 function uses a generator expression when at the same time the
4970 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004971
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004972- sets and frozensets now have an isdisjoint() method.
4973
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004974- optimize the performance of builtin.sum().

4977
Georg Brandl21e99f42010-03-07 15:23:59 +00004978- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004979 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4980 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004981
Georg Brandl3ee81df2008-05-17 18:14:43 +00004982- Issue #1686386: Tuple's tp_repr did not take into account the
4983 possibility of having a self-referential tuple, which is possible
4984 from C code. Nor did object's tp_str consider that a type's tp_str
4985 could do something that could lead to an inifinite recursion.
4986 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4987 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004988
Georg Brandl3ee81df2008-05-17 18:14:43 +00004989- Issue #1164: It was possible to trigger deadlock when using the
4990 'print' statement to write to a file since the GIL was not released
4991 as needed. Now PyObject_Print() does the right thing along with
4992 various tp_print implementations of the built-in types and those in
4993 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004994
Georg Brandl3ee81df2008-05-17 18:14:43 +00004995- Issue #1147: Exceptions were directly allowing string exceptions in
4996 their throw() method even though string exceptions no longer
4997 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004998

Brett Cannon1e534b52007-09-07 04:18:30 +00005002- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005003 PyObject_Call() never calling back out to Python code to trigger
5004 recursion depth updates/checks. Required the creation of a static
5005 RuntimeError instance in case normalizing an exception put the
5006 recursion check value past its limit. Fixes crashers
5007 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005008

Neal Norwitz0ac60192007-05-27 04:08:54 +00005022- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005023 __*__ attributes. (Some already existed, e.g., __doc__ and
5024 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005025
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005026- Add -3 option to the interpreter to warn about features that are
5027 deprecated and will be changed/removed in Python 3.0.
5028
Georg Brandl2134e752007-05-21 20:34:16 +00005029- Patch #1686487: you can now pass any mapping after '**' in function
5030 calls.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005033 "except E as target:". This is to provide forwards compatibility
5034 with Python 3.0.

Guido van Rossum143b5642007-03-23 04:58:42 +00005055- Bug #1683368: The object.__init__() and object.__new__() methods are
5056 now stricter in rejecting excess arguments. The only time when
5057 either allows excess arguments is when it is not overridden and the
5058 other one is. For backwards compatibility, when both are
5059 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005060 warning later). Also, type.__init__() insists on the same signature
5061 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005063- Patch #1675423: PyComplex_AsCComplex() now tries to convert an

5065 to the __float__() method. Therefore, the functions in the cmath
5066 module now can operate on objects that define a __complex__()
5067 method.

5087
Georg Brandl871f1bc2007-03-12 13:17:36 +00005088- The dir() function has been extended to call the __dir__() method on

5090 allows customizing the output of dir() in the presence of a

Georg Brandlaa2321b2007-03-07 00:40:28 +00005103- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005104 makes the filenames the warning module prints much more sensible

Georg Brandl3ee81df2008-05-17 18:14:43 +00006033- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6034 with RFC 3207 and forgets any knowledge obtained from the server not
6035 obtained from the TLS negotiation itself. Patch contributed by Bill
6036 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006037
Georg Brandl3ee81df2008-05-17 18:14:43 +00006038- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006039 that the SMTP.starttls() caller no longer needs to call ehlo()
6040 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006041 does not claim to support starttls. Adds the
6042 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6123 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6124 silently miscode subclasses of those types. Now, it raises a
6125 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006126

Georg Brandl3ee81df2008-05-17 18:14:43 +00006141 time so that opening a database previously created with the DB_DUP
6142 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6143 opens. Specifically: dictionary assignment to a DB object will
6144 replace all values for a given key when the database allows
6145 duplicate values. DB users should use DB.put(k, v) when they want
6146 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006147

6153 characters with ASCII value less than 32. Also, it correctly quotes
6154 dots only if they occur on a single line, as opposed to the previous
6155 behavior of quoting dots if they are the second character of any
6156 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006157

Georg Brandl3ee81df2008-05-17 18:14:43 +00006501- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6502 of w# format code incorrectly truncated the length to an int, even
6503 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6504 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006506- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6507 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006509- PEP 3123: Provide forward compatibility with Python 3.0, while
6510 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6511 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006513- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6514 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006515
6516- Patch #1733960: Allow T_LONGLONG to accept ints.
6517
6518- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6519
Christian Heimes000a0742008-01-03 22:16:32 +00006520- Added a new API function ``PyImport_ImportModuleNoBlock``.

Georg Brandl6caad7d2008-01-26 14:19:22 +00006522- Bug #1637022: Prefix AST symbols with _Py_.
6523
6524- Fix some leftovers from the conversion from int to Py_ssize_t
6525 (relevant to strings and sequences of more than 2**31 items).
6526
6527- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6528 outside of pystate.c and should not be necessary.
6529
Georg Brandl3ee81df2008-05-17 18:14:43 +00006530- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do

Georg Brandl3ee81df2008-05-17 18:14:43 +00006534- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6535 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006536
Georg Brandl3ee81df2008-05-17 18:14:43 +00006537- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006544- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6545 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6546 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6547 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006562- Removed the macfs module. It had been deprecated since Python 2.5.
6563 This lead to the deprecation of macostools.touched() as it relied
6564 solely on macfs and was a no-op under OS X.
