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.

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

45
Raymond Hettinger74f869e2010-09-13 22:14:36 +000046- Issue #9826: OrderedDict.__repr__ can now handle self-referential
47 values: d['x'] = d.
48
Victor Stinner46287f52010-09-13 20:31:34 +000049- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X
50 (macpath module).
51
Antoine Pitroue4195e82010-09-12 14:56:27 +000052- Issue #9837: The read() method of ZipExtFile objects (as returned by
53 ZipFile.open()) could return more bytes than requested.
54
Raymond Hettinger20397532010-09-12 02:11:45 +000055- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
56 This prevents user-created self-referencing ordered dictionaries from
57 becoming permanently uncollectable GC garbage. The downside is that
58 removing __del__ means that the internal doubly-linked list has to wait for
59 GC collection rather than freeing memory immediately when the refcnt drops
60 to zero.
61
Raymond Hettingerffd2a422010-09-10 10:47:22 +000062- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
63 different internal state for small values of n. Fixed by salting the
64 value.
65
Antoine Pitrouc818ed42010-09-07 21:40:25 +000066- Issue #9792: In case of connection failure, socket.create_connection()
67 would swallow the exception and raise a new one, making it impossible
68 to fetch the original errno, or to filter timeout errors. Now the
69 original error is re-raised.
70
Antoine Pitrouf4f61712010-09-07 16:34:47 +000071- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
72 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
73 be updated back after the system call. Original patch by Brian Brazil.
74
Antoine Pitroudca9de92010-09-04 17:52:26 +000075- Issue #1100562: Fix deep-copying of objects derived from the list and
76 dict types. Patch by Michele Orrù and Björn Lindqvist.
77
Fred Drakea1e627d2010-09-03 03:55:50 +000078- Issue #7005: Fixed output of None values for RawConfigParser.write and
79 ConfigParser.write.
80
Daniel Stutzbach66c981b2010-08-31 20:29:39 +000081- Issue #808164: Fixed socket.close to avoid references to globals, to
82 avoid issues when socket.close is called from a __del__ method.
83
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +000084- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
85 falling into recursion.
86
R. David Murray7c4bf552010-08-25 01:45:57 +000087- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
88 character years even if the message contains RFC822 two character years.
89
Daniel Stutzbach91287322010-08-24 21:09:30 +000090- Issue #8750: Fixed MutableSet's methods to correctly handle
91 reflexive operations, namely x -= x and x ^= x.
92
Victor Stinnercaafd772010-09-08 10:51:01 +000093- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +000094 error handling when accepting a new connection.
95
Giampaolo Rodolà63308d72010-08-23 21:58:47 +000096- Issue #658749: asyncore's connect() method now correctly interprets winsock
97 errors.
98
Vinay Sajip1ddd51f2010-08-23 17:50:30 +000099- Issue #9501: Fixed logging regressions in cleanup code.

102 module now correctly return a set. (Patch by Eli Bendersky.)
103
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000104- Issue #9617: Signals received during a low-level write operation aren't
105 ignored by the buffered IO layer anymore.
106
Benjamin Peterson52c36052010-08-21 03:03:22 +0000107- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
108 are not held onto after they are deleted elsewhere.
109
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000110- Issue #9626: the view methods for collections.OrderedDict() were returning
111 the unordered versions inherited from dict. Those methods are now
112 overridden to provide ordered views.
113
Éric Araujo0389ae62010-08-14 03:07:46 +0000114- Issue #8688: MANIFEST files created by distutils now include a magic
115 comment indicating they are generated. Manually maintained MANIFESTs
116 without this marker will not be overwritten or removed.
117
Antoine Pitroue1436d12010-08-12 15:25:51 +0000118- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
119 and a BadZipfile error is raised if it doesn't match (as used to be the
120 case in Python 2.5 and earlier).
121
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000122- Issue #9550: a BufferedReader could issue an additional read when the
123 original read request had been satisfied, which could block indefinitely
124 when the underlying raw IO channel was e.g. a socket. Report and original
125 patch by Jason V. Miller.
126
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000127- Issue #9551: Don't raise TypeError when setting the value to None for
128 SafeConfigParser instances constructed with allow_no_value == True.

131 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
132
Antoine Pitrou99009162010-08-09 22:51:24 +0000133- Issue #3757: thread-local objects now support cyclic garbage collection.
134 Thread-local objects involved in reference cycles will be deallocated
135 timely by the cyclic GC, even if the underlying thread is still running.
136
Florent Xicluna2f1b1ff2010-08-09 20:46:49 +0000137- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the

146 This is how it is supposed to work, wget and curl do the same. Previous
147 behavior was wrong.
148
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +0000149- Issue #2944: asyncore doesn't handle connection refused correctly.

156 does not contain a '-', instead of raising an error.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000480- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
481 start byte and the continuation byte(s) are now considered invalid, instead
482 of the number of bytes specified by the start byte.
483 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
484 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
485 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

495 objects. (1) The comparison could incorrectly return True in some cases
496 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000638- Issue #1533: Fix inconsistency in range function argument processing: any
639 non-float non-integer argument is now converted to an integer (if possible)

694 trapped, the specification determines the order in which the signals should be

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000862
863Core and Builtins
864-----------------
865
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000866- Issue #7301: Add environment variable $PYTHONWARNINGS.
867
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000868- Issue #8329: Don't return the same lists from select.select when no fds are
869 changed.
870
Georg Brandlfee0f442010-05-22 21:26:21 +0000871- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000872 on 64-bit machines. The shift count for either left or right shift is
873 permitted to be up to sys.maxsize.
874
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000875- Ensure that tokenization of identifiers is not affected by locale.
876
Georg Brandlfee0f442010-05-22 21:26:21 +0000877- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000878
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000879- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
880
Georg Brandlfee0f442010-05-22 21:26:21 +0000881- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
882 with a non-empty format string. This is an effort to future-proof user
883 code. If a derived class does not currently implement __format__ but later
884 adds its own __format__, it would most likely break user code that had
885 supplied a format string. This will be changed to a DeprecationWaring in
886 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000887
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000888- Issue #8268: Old-style classes (not just instances) now support weak
889 references.
890
Georg Brandlfee0f442010-05-22 21:26:21 +0000891- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
892 is set.

Victor Stinnerc7790ed2010-03-22 12:36:28 +0000894- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +0000895
Benjamin Peterson96545892010-03-21 20:21:00 +0000896- Issue #6474: Make error message from passing an inadequate number of keyword
897 arguments to a function correct.
898
Benjamin Peterson0dee9c12010-03-17 20:41:42 +0000899- Issue #8164: Don't allow lambda functions to have a docstring.
900
Victor Stinner66644262010-03-10 22:30:19 +0000901- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +0000902 (SIGINT). If an error occurs while importing the site module, the error is
903 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000904 module.

912
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000913- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000914 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
915 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000916

Georg Brandlfee0f442010-05-22 21:26:21 +0000919- Issue #8257: The Decimal construct now accepts a float instance directly,
920 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000921
922 >>> Decimal(1.1)
923 Decimal('1.100000000000000088817841970012523233890533447265625')
924
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000925- collections.Counter() now supports a subtract() method.
926
Georg Brandlfee0f442010-05-22 21:26:21 +0000927- The functools module now has a total_ordering() class decorator to simplify
928 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000929
Georg Brandlfee0f442010-05-22 21:26:21 +0000930- The functools module also adds cmp_to_key() as a tool to transition old-style
931 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000932
Georg Brandlfee0f442010-05-22 21:26:21 +0000933- Issue #8294: The Fraction constructor now accepts Decimal and float instances
934 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000935
Georg Brandlfee0f442010-05-22 21:26:21 +0000936- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
937 InvalidOperation instead of returning False. (Comparisons involving a quiet
938 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
939 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000940
Georg Brandlfee0f442010-05-22 21:26:21 +0000941- Issue #2531: Comparison operations between floats and Decimal instances now
942 return a result based on the numeric values of the operands; previously they
943 returned an arbitrary result based on the relative ordering of id(float) and
944 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000945
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000946- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000947 argument `-` which tells it to read files to compile from stdin. Each line is
948 read on demand and the named file is compiled immediately. (Original patch by
949 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000950
Georg Brandlfee0f442010-05-22 21:26:21 +0000951- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000954- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
955 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000956 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000957
Georg Brandlfee0f442010-05-22 21:26:21 +0000958- Comparisons using one of <, <=, >, >= between a complex instance and a
959 Fractions instance now raise TypeError instead of returning True/False. This
960 makes Fraction <=> complex comparisons consistent with int <=> complex, float
961 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000962

971
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000972- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000973 didn't support chflags() (for example ZFS under FreeBSD). The error is now
974 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000975
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000976- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
977 deprecated.
978
Georg Brandlfee0f442010-05-22 21:26:21 +0000979- Issue #7860: platform.uname now reports the correct 'machine' type when Python
980 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +0000981

986 existing at the same time, causing a Unicode error when configuration code
987 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +0000988
Georg Brandlfee0f442010-05-22 21:26:21 +0000989- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
990 when logging occurs.

Antoine Pitroueee91cd2010-03-26 19:27:16 +0000992- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
993 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
994 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000995

Georg Brandlfee0f442010-05-22 21:26:21 +00001012- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set
1013 to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +00001014 program name.
Victor Stinner75227342010-03-12 14:30:26 +00001015
Vinay Sajipecfa08f2010-03-12 09:16:10 +00001016- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001017 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1018 log file to compute the next rollover time. If the log file does not exist,
1019 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001020
Georg Brandlba83f822010-03-14 09:50:54 +00001021- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001029- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1030 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1031 This is a behavior change, so email's minor version number is now bumped, to
1032 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +00001033

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001060- Issue #8300: When passing a non-integer argument to struct.pack with any
1061 integer format code, struct.pack first attempts to convert the non-integer
1062 using its __index__ method. If that method is non-existent or raises
1063 TypeError it goes on to try the __int__ method, as described below.
1064
Georg Brandlba83f822010-03-14 09:50:54 +00001065- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1066 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1067 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001068 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1069 inconsistent: __int__ was used for some integer codes but not for others, and
1070 the set of integer codes for which it was used differed between native packing
1071 and standard packing.)

Mark Dickinson8efef5c2010-01-12 22:23:56 +00001330
Georg Brandlba83f822010-03-14 09:50:54 +00001331 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
1332 strings,
1333 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1334 numeric strings corresponding to subnormal values,
1335 (3) a memory leak for some values large enough to cause overflow, and
1336 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00001375 file position when calling `truncate()`. It would previously change the file
1376 position to the given argument, which goes against the tradition of

1471Core and Builtins
1472-----------------
1473
Georg Brandlba83f822010-03-14 09:50:54 +00001474- The ``__complex__()`` method is now looked up on the class of instances to
1475 make it consistent with other special methods.

1479
Mark Dickinson1b34d252010-01-01 17:27:30 +00001480- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001481 DeprecationWarning when passed a float argument where an integer was expected.
1482 These functions and methods now raise TypeError instead. The majority of the
1483 effects of this change are in the extension modules, but some core functions
1484 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1485 and many unicode/str methods.

1499 of integers: the result of a/b is now correctly rounded for ints a and b (at
1500 least on IEEE 754 platforms), and in particular does not depend on the
1501 internal representation of a long.

1509
Georg Brandlba83f822010-03-14 09:50:54 +00001510 These executables now work properly with the arch(1) command: ``arch -ppc
1511 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001668- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1669 decimal string that's guaranteed to round back to x under correct rounding
1670 (with round-half-to-even rounding mode). Previously it gave a string based on
1671 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1672 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1673 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001674
Georg Brandlba83f822010-03-14 09:50:54 +00001675- Issue #7117: On almost all platforms: float-to-string and string-to-float
1676 conversions within Python are now correctly rounded. Places these conversions
1677 occur include: str for floats and complex numbers; the float and complex
1678 constructors; old-style and new-style numeric formatting; serialization and
1679 deserialization of floats and complex numbers using marshal, pickle and json;
1680 parsing of float and imaginary literals in Python code; Decimal-to-float
1681 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001682
Georg Brandlba83f822010-03-14 09:50:54 +00001683 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1684 providing correctly-rounded strtod and dtoa C functions. This code is
1685 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1686 the C compiler. There may be a small number of platforms on which correct
1687 operation of this code cannot be guaranteed, so the code is not used: notably,
1688 this applies to platforms where the C double format is not IEEE 754 binary64,
1689 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1690 and Python's configure script is unable to determine how to change the FPU
1691 precision. On these platforms conversions use the platform strtod and dtoa,
1692 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001694- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1695 uses the correctly-rounded string <-> float conversions described above (when
1696 available), and so produces correctly rounded results that will display nicely
1697 under the float repr. There are two related small changes: (1) round now
1698 accepts any class with an ``__index__()`` method for its second argument (but
1699 no longer accepts floats for the second argument), and (2) an excessively
1700 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1701 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001844 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1845 (2) parsing of strings representing infinities and nans was locale aware; and
1846 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001848- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1849 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1850 but with at least one decimal point and with a default precision
1851 of 12. Previously, the behavior the same but with a default precision of 6.
1852 This more closely matches ``str()``, and reduces surprises when adding
1853 alignment flags to the empty presentation type. This also affects the new
1854 complex.__format__ in the same way.
1855
1856- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00002037- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2038 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2039 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002042- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2045
Georg Brandlba83f822010-03-14 09:50:54 +00002046- Issue #3689: The list reversed iterator now supports __length_hint__ instead

2051
Georg Brandlba83f822010-03-14 09:50:54 +00002052- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2053 file objects with closefd=False. The file descriptor is still kept open but
2054 the file object behaves like a closed file. The ``FileIO`` object also got a
2055 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002075- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002078- On windows, ``os.chdir()`` given unicode was not working if

2080 this code path is really executed because I cannot move to such directory on
2081 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002083- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2084 element is temporarily replaced with an equivalent frozenset. But the
2085 eventual KeyError would always report the empty ``frozenset()`` as the missing
2086 key. Now it correctly refers to the initial element.

2105
Walter Dörwalded960ac2009-05-03 22:36:33 +00002106- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2107 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2108 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2109 of using the replace error handler in PyUnicode_DecodeUTF8().
2110
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002111- Issue #3739: The unicode-internal encoder now reports the number of characters

2113
Georg Brandlba83f822010-03-14 09:50:54 +00002114- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2115 allocator will be automatically disabled when running under Valgrind. This
2116 gives improved memory leak detection when running under Valgrind, while taking
2117 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003482- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3483
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003484- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3485 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3486 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3487 ``printf`` function, whereas PyString_FromFormat has an independent
3488 implementation and uses "%zd" on all platforms for size_t values.
3489 This makes a difference on win64, where ``printf`` needs "%Id" to display
3490 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003492- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3496 object; previously an int would be returned for small values. the __long__
3497 method is allowed to return either an int or a long, but the behaviour of
3498 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003500- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003507 was correctly parsed but parsing of subsequent arguments failed.
3508
Vinay Sajip35e3b032008-09-01 14:33:59 +00003509- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003510 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3511 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3512 when given a tuple of classes as second argument, were looking up
3513 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3514 type object.

3659-----------------
3660
Guido van Rossumf8402962008-08-20 15:01:50 +00003661- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3662 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3663 extensions do not automatically benefit from the class attribute
3664 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3665 to their tp_flags field if they care. This is a backwards
3666 compatibility feature; in 3.0, all types will use the cache by
3667 default.
3668
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003669- Keyword arguments can now follow starred arguments. (``f(a, *args,

3671
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003672- ctypes function pointers that are COM methods have a boolean True
3673 value again.

3684
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003685- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3686 (64bit Unix, for example), unichr() would truncate its argument and return
3687 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Antoine Pitrou92f82162008-07-25 22:22:08 +00003694- Issue #1819: function calls with several named parameters are now on

3696
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003697- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3698 the python debugger steps into a class statement: the free variables (local

Gregory P. Smith0470bab2008-07-22 04:46:32 +00003701- Issue #2620: Overflow checking when allocating or reallocating memory
3702 was not always being done properly in some python types and extension
3703 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3704 all been updated to perform better checks and places in the code that
3705 would previously leak memory on the error path when such an allocation
3706 failed have been fixed.

3714 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3715
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003716- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3717 version reported by these tools does not necessarily follow the python
3718 version numbering scheme, so the module is less strict when parsing it.
3719
Nick Coghlanf70385a2008-08-18 12:42:46 +00003720- Issue #2235: Added Py3k warnings for types which will become unhashable
3721 under the stricter __hash__ inheritance rules in 3.0. Several types
3722 which did not meet the rules for hash invariants and were already
3723 unhashable in 3.0 have now been explicitly flagged as unhashable in
3724 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3725 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3726
Brett Cannon88f801d2008-08-18 00:46:22 +00003727- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3759 since mimetools itself is deprecated. Because modules are cached, all
3760 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

3771 a MemoryError rather than silently stop the iteration.
3772

3774 to _sre.compile() will now be rejected. This should not affect anybody
3775 since the re.compile() function never generates invalid re-bytecode.
3776
Skip Montanaroa032bf42008-08-08 22:52:51 +00003777- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3778 upon first access it can be automatically initialized from the csv file if
3779 it wasn't initialized during instantiation.
3780
Brett Cannon3aa2a492008-08-06 22:28:09 +00003781- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3782 the reload() built-in has been removed.
3783
Brett Cannon7e30b672008-08-04 21:52:25 +00003784- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003785 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003796 asking for a specific length. This problem only affected files opened
3797 using the new "io" module, not the built-in open() function.

3823 file name rather than a ZipInfo instance, so files are extracted with
3824 mode 0600 rather than 000 under Unix.
3825
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003826- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3839 interaction with the tp_hash slot (added in 2.6b2) are now documented
3840
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003841- Issue #643841: The language reference now provides more detailed
3842 coverage of the lookup process for special methods. The disclaimers
3843 regarding lack of coverage of new-style classes have also been
3844 removed, since the coverage is now fairly reasonable.

3848================================
3849
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003850*Release date: 17-Jul-2008*
3851
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003852Core and Builtins
3853-----------------
3854
Georg Brandl3e483f62008-07-16 22:57:41 +00003855- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3856 its methods now allow for items objects that can be converted to
3857 an integer using operator.index().
3858
Mark Dickinson64b7e502008-07-16 09:40:03 +00003859- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3860 produced a ValueError instead of giving the correct float.
3861
Eric Smitha5fa5a22008-07-16 00:11:49 +00003862- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3863 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3864
Mark Dickinson7103aa42008-07-15 19:08:33 +00003865- Issue #3008: the float type has a new instance method 'float.hex'
3866 and a new class method 'float.fromhex' to convert floating-point
3867 numbers to and from hexadecimal strings, respectively.
3868
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003869- Issue #2235: __hash__ is once again inherited by default. To allow
3870 collections.Hashable to remain meaningful in the presence of the
3871 default hash implementation (object.__hash__), it is now possible
3872 to explicit block inheritance of hash by setting __hash__=None at
3873 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3874 level.
3875
Nick Coghlanb028f502008-07-13 14:52:36 +00003876- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3877 the parent module cannot be found while performing an absolute import.
3878 This means that an incorrectly defined __package__ attribute will
3879 now only prevent relative imports in that module rather than causing
3880 all imports from that module to fail.
3881
Nick Coghlan14ff9942008-07-08 14:21:42 +00003882- Issue #2517: Allow unicode messages in Exceptions again by correctly
3883 bypassing the instance dictionary when looking up __unicode__ on
3884 new-style classes.
3885
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003886- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3887 set to a custom object whose write() method happens to install
3888 another file in sys.stdout.
3889
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003890- Issue #3088: Corrected a race condition in classes derived from
3891 threading.local: the first member set by a thread could be saved in
3892 another thread's dictionary.
3893
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003894- Issue #3004: Minor change to slice.indices(): the start and stop
3895 arguments are now treated identically, making the behaviour easier
3896 to describe and understand. For example, slice(None, -10,
3897 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3898 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3899 10, -1).
3900
Georg Brandl278fc502008-07-19 12:46:12 +00003901- Issue #3219: Calling a function with repeated keyword arguments,
3902 f(a=2, a=23), would not cause a syntax error. This was a regression
3903 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003904
Georg Brandl278fc502008-07-19 12:46:12 +00003905- Issue #2862: Make int and float freelist management consistent with
3906 other freelists. Changes their CompactFreeList apis into
3907 ClearFreeList apis and calls them via gc.collect().

3913 api functions without holding the GIL, which could lead to a fatal
3914 error when they failed.
3915
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003916- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3925 ForkingPickler.register() to resolve conflict with ctypes.
3926
Vinay Sajip51e65192008-07-18 09:01:10 +00003927- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

3930 a valid dlerror() message.
3931
Thomas Heller2bad6572008-07-15 17:19:50 +00003932- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3933 incomplete structure was created.
3934

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003939- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003940
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003941- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3942 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003943 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003944 content-length. The problem had been corrected in the 2.4 branch, but never
3945 merged into trunk.
3946

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003960- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3961 handling is now the same as that of other special attributes like __name__).
3962
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003963- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3964 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004353 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004354
4355 This is controlled by the configure argument ``--with-universal-archs``:
4356
4357 - ``--with-universal-archs=all``: install 4-way universal
4358
4359 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4360
4361 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4362
4363 This option should be used in combination with ``--enable-universalsdk=``.
4364
4365 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 +00004415- Issue #1631171: Re-implement the 'warnings' module in C (the
4416 original Python code has been kept as backup). This will allow for
4417 using the 'warning's machinery in such places as the parser where
4418 use of pure Python code is not possible. Both the ``showarning()``
4419 and ``formatwarning()`` gain an optional 'line' argument which is
4420 not called by default for backwards-compatibility reasons. Setting
4421 ``warnings.showwarning()`` to an implementation that lacks support
4422 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- Issue #2550: The approach used by client/server code for obtaining
4486 ports to listen on in network-oriented tests has been refined in an
4487 effort to facilitate running multiple instances of the entire
4488 regression test suite in parallel without issue.
4489 test_support.bind_port() has been fixed such that it will always
4490 return a unique port -- which wasn't always the case with the
4491 previous implementation, especially if socket options had been set
4492 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4493 new implementation of bind_port() will actually raise an exception
4494 if it is passed an AF_INET/SOCK_STREAM socket with either the
4495 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4496 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4497 the socket it's been passed. This currently only applies to
4498 Windows. This option prevents any other sockets from binding to the
4499 host/port we've bound to, thus removing the possibility of the
4500 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4501 when a second SOCK_STREAM socket binds and accepts to a host/port
4502 that's already been bound by another socket. The optional preferred
4503 port parameter to bind_port() has been removed. Under no
4504 circumstances should tests be hard coding ports!
4505
4506 test_support.find_unused_port() has also been introduced, which will
4507 pass a temporary socket object to bind_port() in order to obtain an
4508 unused port. The temporary socket object is then closed and
4509 deleted, and the port is returned. This method should only be used
4510 for obtaining an unused port in order to pass to an external program
4511 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4512 a parameter to a server-oriented class that doesn't give you direct
4513 access to the underlying socket used.
4514
4515 Finally, test_support.HOST has been introduced, which should be used
4516 for the host argument of any relevant socket calls (i.e. bind and
4517 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004518
4519 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004520 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004521 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4522 test_asynchat and test_socket_ssl.
4523
Georg Brandl3ee81df2008-05-17 18:14:43 +00004524 It is now possible for multiple instances of the regression test
4525 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00004794- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004795 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004796
Georg Brandlad61bc82008-02-23 15:11:18 +00004797- Issue #2067: file.__exit__() now calls subclasses' close() method.
4798
4799- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004800
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004801- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00004802 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00004803
Eric Smitha73fbe72008-02-23 03:09:44 +00004804- Added the future_builtins module, which contains hex() and oct().
4805 These are the PEP 3127 version of these functions, designed to be
4806 compatible with the hex() and oct() builtins from Python 3.0. They
4807 differ slightly in their output formats from the existing, unchanged
4808 Python 2.6 builtins. The expected usage of the future_builtins
4809 module is:
4810 from future_builtins import hex, oct
4811
Eric Smith7ef40bf2008-02-20 23:34:22 +00004812- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4813 exponents for exponents with absolute value < 100. Follows C99
4814 standard. This is a change on Windows, which would use 3 digits.
4815 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4816 so that any alterations it does to the resulting string will be
4817 available in stringlib/formatter.h (for float.__format__).
4818
Eric Smith5a3c1352008-02-19 13:21:56 +00004819- Implemented PEP 3101, Advanced String Formatting. This adds a new
4820 builtin format(); a format() method for str and unicode; a
4821 __format__() method to object, str, unicode, int, long, float, and
4822 datetime; the class string.Formatter; and the C API
4823 PyObject_Format().
4824
Georg Brandl3ee81df2008-05-17 18:14:43 +00004825- Fixed several potential crashes, all caused by specially crafted
4826 __del__ methods exploiting objects in temporarily inconsistent
4827 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004828
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004829- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004830 prevent a possible crash: an Abstract Base Class would try to access
4831 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004832
Georg Brandl3ee81df2008-05-17 18:14:43 +00004833- Fixed repr() and str() of complex numbers with infinity or nan as
4834 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004835
Georg Brandl3ee81df2008-05-17 18:14:43 +00004836- Clear all free lists during a gc.collect() of the highest generation
4837 in order to allow pymalloc to free more arenas. Python may give back
4838 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004839
Georg Brandl3ee81df2008-05-17 18:14:43 +00004840- Issue #2045: Fix an infinite recursion triggered when printing a
4841 subclass of collections.defaultdict, if its default_factory is set
4842 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004843
Christian Heimesf75dbef2008-02-08 00:11:31 +00004844- Fixed a minor memory leak in dictobject.c. The content of the free
4845 list was not freed on interpreter shutdown.
4846
Georg Brandl21e99f42010-03-07 15:23:59 +00004847- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004848 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004849
Georg Brandl3ee81df2008-05-17 18:14:43 +00004850- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4851 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004852 to compact the internal free lists of pre-allocted ints and floats.
4853
Georg Brandl3ee81df2008-05-17 18:14:43 +00004854- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4855 calls. Python expected the return type int but the fork familie
4856 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004857
Georg Brandl3ee81df2008-05-17 18:14:43 +00004858- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4859 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004860
Georg Brandl3ee81df2008-05-17 18:14:43 +00004861- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4862 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004863
Georg Brandl3ee81df2008-05-17 18:14:43 +00004864- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4865 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004867- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4868 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004869
Georg Brandl3ee81df2008-05-17 18:14:43 +00004870- Patch #1473257: generator objects gain a gi_code attribute. This is
4871 the same object as the func_code attribute of the function that
4872 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004873
Georg Brandl3ee81df2008-05-17 18:14:43 +00004874- Issue #1920: "while 0" statements were completely removed by the
4875 compiler, even in the presence of an "else" clause, which is
4876 supposed to be run when the condition is false. Now the compiler
4877 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004878
Guido van Rossumeead05f2008-01-24 18:21:02 +00004879- A few crashers fixed: weakref_in_del.py (issue #1377858);
4880 loosing_dict_ref.py (issue #1303614, test67.py);
4881 borrowed_ref_[34].py (not in tracker).
4882
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004883- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004884 suppressed while an extension is loaded by calling SetErrorMode in
4885 dynload_win.c. The error is still reported properly.
4886
Georg Brandl3ee81df2008-05-17 18:14:43 +00004887- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004888 several extension methods and modules do not work without unicode
4889 support.
4890
Georg Brandl26543b12008-01-21 18:36:51 +00004891- Issue #1882: when compiling code from a string, encoding cookies in the
4892 second line of code were not always recognized correctly.
4893
Georg Brandl14404b62008-01-19 19:27:05 +00004894- Issue #1679: "0x" was taken as a valid integer literal.
4895
Georg Brandl6caad7d2008-01-26 14:19:22 +00004896- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004897 added.
4898
Christian Heimesc94e2b52008-01-14 04:13:37 +00004899- sys.float_info / PyFloat_GetInfo: The floating point information
4900 object was converted from a dict to a specialized structseq object.
4901
Georg Brandl3ee81df2008-05-17 18:14:43 +00004902- Patch #1816: Added sys.flags structseq. It exposes the status of
4903 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004904
Georg Brandl3ee81df2008-05-17 18:14:43 +00004905- Objects/structseq.c: Implemented new structseq representation. The
4906 patch makes structseqs (e.g. the return value of os.stat) more
4907 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004908
Georg Brandl3ee81df2008-05-17 18:14:43 +00004909- Patch #1700288: added a type attribute cache that caches method
4910 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004911
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004912- Bug #1776: __import__() no longer accepts filenames on any platform.
4913 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004914

4916
Georg Brandl3ee81df2008-05-17 18:14:43 +00004917- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4918 envvar and sys.dont_write_bytecode attribute. All these can be set
4919 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004920
Georg Brandl3ee81df2008-05-17 18:14:43 +00004921- Improve some exception messages when Windows fails to load an
4922 extension module. Now we get for example '%1 is not a valid Win32
4923 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004924
Georg Brandl3ee81df2008-05-17 18:14:43 +00004925- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004927- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4928 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004929
Christian Heimes0a8143f2007-12-18 23:22:54 +00004930- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004931 and INF. float("nan"), float("inf") and float("-inf") now work on
4932 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004933
Georg Brandl3ee81df2008-05-17 18:14:43 +00004934- Compiler now generates simpler and faster code for dictionary
4935 literals. The oparg for BUILD_MAP now indicates an estimated
4936 dictionary size. There is a new opcode, STORE_MAP, for adding
4937 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004938

4967 file can now be directly executed by passing their name to the
4968 interpreter. The directory/zipfile is automatically inserted as the
4969 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004970
Georg Brandl3ee81df2008-05-17 18:14:43 +00004971- Issue #1265: Fix a problem with sys.settrace, if the tracing
4972 function uses a generator expression when at the same time the
4973 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004974
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004975- sets and frozensets now have an isdisjoint() method.
4976
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004977- optimize the performance of builtin.sum().

4980
Georg Brandl21e99f42010-03-07 15:23:59 +00004981- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004982 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4983 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004984
Georg Brandl3ee81df2008-05-17 18:14:43 +00004985- Issue #1686386: Tuple's tp_repr did not take into account the
4986 possibility of having a self-referential tuple, which is possible
4987 from C code. Nor did object's tp_str consider that a type's tp_str
4988 could do something that could lead to an inifinite recursion.
4989 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4990 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004991
Georg Brandl3ee81df2008-05-17 18:14:43 +00004992- Issue #1164: It was possible to trigger deadlock when using the
4993 'print' statement to write to a file since the GIL was not released
4994 as needed. Now PyObject_Print() does the right thing along with
4995 various tp_print implementations of the built-in types and those in
4996 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004997
Georg Brandl3ee81df2008-05-17 18:14:43 +00004998- Issue #1147: Exceptions were directly allowing string exceptions in
4999 their throw() method even though string exceptions no longer
5000 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005001

Brett Cannon1e534b52007-09-07 04:18:30 +00005005- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005006 PyObject_Call() never calling back out to Python code to trigger
5007 recursion depth updates/checks. Required the creation of a static
5008 RuntimeError instance in case normalizing an exception put the
5009 recursion check value past its limit. Fixes crashers
5010 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005011

Neal Norwitz0ac60192007-05-27 04:08:54 +00005025- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005026 __*__ attributes. (Some already existed, e.g., __doc__ and
5027 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005028
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005029- Add -3 option to the interpreter to warn about features that are
5030 deprecated and will be changed/removed in Python 3.0.
5031
Georg Brandl2134e752007-05-21 20:34:16 +00005032- Patch #1686487: you can now pass any mapping after '**' in function
5033 calls.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005036 "except E as target:". This is to provide forwards compatibility
5037 with Python 3.0.

Guido van Rossum143b5642007-03-23 04:58:42 +00005058- Bug #1683368: The object.__init__() and object.__new__() methods are
5059 now stricter in rejecting excess arguments. The only time when
5060 either allows excess arguments is when it is not overridden and the
5061 other one is. For backwards compatibility, when both are
5062 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005063 warning later). Also, type.__init__() insists on the same signature
5064 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005066- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5067 object to complex using its __complex__() method before falling back
5068 to the __float__() method. Therefore, the functions in the cmath
5069 module now can operate on objects that define a __complex__()
5070 method.

5090
Georg Brandl871f1bc2007-03-12 13:17:36 +00005091- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005092 its argument, if it exists. If not, it will work like before. This
5093 allows customizing the output of dir() in the presence of a

Georg Brandlaa2321b2007-03-07 00:40:28 +00005106- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005107 makes the filenames the warning module prints much more sensible
5108 when a PYTHONSTARTUP file is used.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005659 AttributeError instead of an IOError when the server's response

5751 TestCase and TestSuite subclasses (not instances) are no longer

5754 -- the failure just occurred later, with a more cumbersome
5755 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006036- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6037 with RFC 3207 and forgets any knowledge obtained from the server not
6038 obtained from the TLS negotiation itself. Patch contributed by Bill
6039 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006040
Georg Brandl3ee81df2008-05-17 18:14:43 +00006041- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006042 that the SMTP.starttls() caller no longer needs to call ehlo()
6043 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006044 does not claim to support starttls. Adds the
6045 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6126 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6127 silently miscode subclasses of those types. Now, it raises a
6128 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006129

Georg Brandl3ee81df2008-05-17 18:14:43 +00006144 time so that opening a database previously created with the DB_DUP
6145 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6146 opens. Specifically: dictionary assignment to a DB object will
6147 replace all values for a given key when the database allows
6148 duplicate values. DB users should use DB.put(k, v) when they want
6149 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006150

6156 characters with ASCII value less than 32. Also, it correctly quotes
6157 dots only if they occur on a single line, as opposed to the previous
6158 behavior of quoting dots if they are the second character of any
6159 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006160

6502 ``PyFloat_GetInfo()`` to the float API.
6503
Georg Brandl3ee81df2008-05-17 18:14:43 +00006504- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6505 of w# format code incorrectly truncated the length to an int, even
6506 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6507 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006509- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6510 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006512- PEP 3123: Provide forward compatibility with Python 3.0, while
6513 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6514 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006516- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6517 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006518
6519- Patch #1733960: Allow T_LONGLONG to accept ints.
6520
6521- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6522
Christian Heimes000a0742008-01-03 22:16:32 +00006523- Added a new API function ``PyImport_ImportModuleNoBlock``.

6526
6527- Fix some leftovers from the conversion from int to Py_ssize_t
6528 (relevant to strings and sequences of more than 2**31 items).
6529
6530- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6531 outside of pystate.c and should not be necessary.
6532
Georg Brandl3ee81df2008-05-17 18:14:43 +00006533- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do

Georg Brandl3ee81df2008-05-17 18:14:43 +00006537- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6538 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006539
Georg Brandl3ee81df2008-05-17 18:14:43 +00006540- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006547- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6548 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6549 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6550 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006565- Removed the macfs module. It had been deprecated since Python 2.5.
6566 This lead to the deprecation of macostools.touched() as it relied
6567 solely on macfs and was a no-op under OS X.
