12Core and Builtins
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

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

44-------
45
Antoine Pitrou2c7d6852010-09-23 19:55:24 +000046- Issue #9928: Properly initialize the types exported by the bz2 module.
47
Antoine Pitrou6391b342010-09-14 18:48:19 +000048- Issue #9854: The default read() implementation in io.RawIOBase now
49 handles non-blocking readinto() returning None correctly.
50
Antoine Pitrouf7f390a2010-09-14 14:37:18 +000051- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
52 SSLSocket.sendto() to match the corresponding socket methods. Also,
53 fix various SSLSocket methods to raise socket.error rather than an
54 unhelpful TypeError when called on an unconnected socket. Original patch
55 by Andrew Bennetts.
56
Raymond Hettinger74f869e2010-09-13 22:14:36 +000057- Issue #9826: OrderedDict.__repr__ can now handle self-referential
58 values: d['x'] = d.
59
Victor Stinner8fc843b2010-09-17 23:35:50 +000060- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
Victor Stinner46287f52010-09-13 20:31:34 +000061
Antoine Pitroue4195e82010-09-12 14:56:27 +000062- Issue #9837: The read() method of ZipExtFile objects (as returned by
63 ZipFile.open()) could return more bytes than requested.
64
Raymond Hettinger20397532010-09-12 02:11:45 +000065- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
66 This prevents user-created self-referencing ordered dictionaries from
67 becoming permanently uncollectable GC garbage. The downside is that
68 removing __del__ means that the internal doubly-linked list has to wait for
69 GC collection rather than freeing memory immediately when the refcnt drops
70 to zero.
71
Raymond Hettingerffd2a422010-09-10 10:47:22 +000072- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
73 different internal state for small values of n. Fixed by salting the
74 value.
75
Antoine Pitrouc818ed42010-09-07 21:40:25 +000076- Issue #9792: In case of connection failure, socket.create_connection()
77 would swallow the exception and raise a new one, making it impossible
78 to fetch the original errno, or to filter timeout errors. Now the
79 original error is re-raised.
80
Antoine Pitrouf4f61712010-09-07 16:34:47 +000081- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
82 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
83 be updated back after the system call. Original patch by Brian Brazil.
84
Antoine Pitroudca9de92010-09-04 17:52:26 +000085- Issue #1100562: Fix deep-copying of objects derived from the list and
86 dict types. Patch by Michele Orrù and Björn Lindqvist.
87
Fred Drakea1e627d2010-09-03 03:55:50 +000088- Issue #7005: Fixed output of None values for RawConfigParser.write and
89 ConfigParser.write.
90
Daniel Stutzbach66c981b2010-08-31 20:29:39 +000091- Issue #808164: Fixed socket.close to avoid references to globals, to
92 avoid issues when socket.close is called from a __del__ method.
93
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +000094- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
95 falling into recursion.
96
R. David Murray7c4bf552010-08-25 01:45:57 +000097- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
98 character years even if the message contains RFC822 two character years.
99
Daniel Stutzbach91287322010-08-24 21:09:30 +0000100- Issue #8750: Fixed MutableSet's methods to correctly handle
101 reflexive operations, namely x -= x and x ^= x.
102
Victor Stinnercaafd772010-09-08 10:51:01 +0000103- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000104 error handling when accepting a new connection.
105
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000106- Issue #658749: asyncore's connect() method now correctly interprets winsock
107 errors.
108
Vinay Sajip1ddd51f2010-08-23 17:50:30 +0000109- Issue #9501: Fixed logging regressions in cleanup code.
110

115 ignored by the buffered IO layer anymore.
116
Benjamin Peterson52c36052010-08-21 03:03:22 +0000117- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
118 are not held onto after they are deleted elsewhere.
119
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000120- Issue #9626: the view methods for collections.OrderedDict() were returning
121 the unordered versions inherited from dict. Those methods are now
122 overridden to provide ordered views.
123
Éric Araujo0389ae62010-08-14 03:07:46 +0000124- Issue #8688: MANIFEST files created by distutils now include a magic
125 comment indicating they are generated. Manually maintained MANIFESTs
126 without this marker will not be overwritten or removed.
127
Antoine Pitroue1436d12010-08-12 15:25:51 +0000128- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
129 and a BadZipfile error is raised if it doesn't match (as used to be the
130 case in Python 2.5 and earlier).
131
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000132- Issue #9550: a BufferedReader could issue an additional read when the
133 original read request had been satisfied, which could block indefinitely
134 when the underlying raw IO channel was e.g. a socket. Report and original
135 patch by Jason V. Miller.
136
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000137- Issue #9551: Don't raise TypeError when setting the value to None for

141 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
142
Antoine Pitrou99009162010-08-09 22:51:24 +0000143- Issue #3757: thread-local objects now support cyclic garbage collection.
144 Thread-local objects involved in reference cycles will be deallocated
145 timely by the cyclic GC, even if the underlying thread is still running.
146
Florent Xicluna2f1b1ff2010-08-09 20:46:49 +0000147- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the

Senthil Kumarane677ecf2010-08-08 11:56:31 +0000155- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
156 This is how it is supposed to work, wget and curl do the same. Previous
157 behavior was wrong.
158
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +0000159- Issue #2944: asyncore doesn't handle connection refused correctly.

498 start byte and the continuation byte(s) are now considered invalid, instead
499 of the number of bytes specified by the start byte.
500 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
501 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
502 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

513 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000857- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000858 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
859 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
860 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000879
880Core and Builtins
881-----------------
882
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000883- Issue #7301: Add environment variable $PYTHONWARNINGS.
884
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000885- Issue #8329: Don't return the same lists from select.select when no fds are
886 changed.
887
Georg Brandlfee0f442010-05-22 21:26:21 +0000888- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000889 on 64-bit machines. The shift count for either left or right shift is
890 permitted to be up to sys.maxsize.
891
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000892- Ensure that tokenization of identifiers is not affected by locale.
893
Georg Brandlfee0f442010-05-22 21:26:21 +0000894- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000895
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000896- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
897
Georg Brandlfee0f442010-05-22 21:26:21 +0000898- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
899 with a non-empty format string. This is an effort to future-proof user
900 code. If a derived class does not currently implement __format__ but later
901 adds its own __format__, it would most likely break user code that had
902 supplied a format string. This will be changed to a DeprecationWaring in
903 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000904
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000905- Issue #8268: Old-style classes (not just instances) now support weak

929
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000930- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000931 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
932 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000933

935
Georg Brandlfee0f442010-05-22 21:26:21 +0000936- Issue #8257: The Decimal construct now accepts a float instance directly,
937 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000938
939 >>> Decimal(1.1)
940 Decimal('1.100000000000000088817841970012523233890533447265625')
941
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000942- collections.Counter() now supports a subtract() method.
943
Georg Brandlfee0f442010-05-22 21:26:21 +0000944- The functools module now has a total_ordering() class decorator to simplify
945 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000946
Georg Brandlfee0f442010-05-22 21:26:21 +0000947- The functools module also adds cmp_to_key() as a tool to transition old-style
948 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000949
Georg Brandlfee0f442010-05-22 21:26:21 +0000950- Issue #8294: The Fraction constructor now accepts Decimal and float instances
951 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000952
Georg Brandlfee0f442010-05-22 21:26:21 +0000953- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
954 InvalidOperation instead of returning False. (Comparisons involving a quiet
955 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
956 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000957
Georg Brandlfee0f442010-05-22 21:26:21 +0000958- Issue #2531: Comparison operations between floats and Decimal instances now
959 return a result based on the numeric values of the operands; previously they
960 returned an arbitrary result based on the relative ordering of id(float) and
961 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000962
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000963- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000964 argument `-` which tells it to read files to compile from stdin. Each line is
965 read on demand and the named file is compiled immediately. (Original patch by
966 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000967
Georg Brandlfee0f442010-05-22 21:26:21 +0000968- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000971- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
972 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000973 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000974
Georg Brandlfee0f442010-05-22 21:26:21 +0000975- Comparisons using one of <, <=, >, >= between a complex instance and a
976 Fractions instance now raise TypeError instead of returning True/False. This
977 makes Fraction <=> complex comparisons consistent with int <=> complex, float
978 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000979

988
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000989- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000990 didn't support chflags() (for example ZFS under FreeBSD). The error is now
991 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000992
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000993- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
994 deprecated.
995
Georg Brandlfee0f442010-05-22 21:26:21 +0000996- Issue #7860: platform.uname now reports the correct 'machine' type when Python
997 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +0000998

1010 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1011 reads and writes are always retried by OpenSSL itself.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001033- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001034 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1035 log file to compute the next rollover time. If the log file does not exist,
1036 the current time is used as the basis for the computation.

Georg Brandlba83f822010-03-14 09:50:54 +00001046- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1047 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1048 This is a behavior change, so email's minor version number is now bumped, to

Georg Brandlba83f822010-03-14 09:50:54 +00001082- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1083 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1084 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001085 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1086 inconsistent: __int__ was used for some integer codes but not for others, and
1087 the set of integer codes for which it was used differed between native packing
1088 and standard packing.)

1489-----------------
1490
Georg Brandlba83f822010-03-14 09:50:54 +00001491- The ``__complex__()`` method is now looked up on the class of instances to
1492 make it consistent with other special methods.

1496
Mark Dickinson1b34d252010-01-01 17:27:30 +00001497- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001498 DeprecationWarning when passed a float argument where an integer was expected.
1499 These functions and methods now raise TypeError instead. The majority of the
1500 effects of this change are in the extension modules, but some core functions
1501 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1502 and many unicode/str methods.

1516 of integers: the result of a/b is now correctly rounded for ints a and b (at
1517 least on IEEE 754 platforms), and in particular does not depend on the
1518 internal representation of a long.

1526
Georg Brandlba83f822010-03-14 09:50:54 +00001527 These executables now work properly with the arch(1) command: ``arch -ppc
1528 python`` will start a universal binary version of python in PPC mode (unlike

1668 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1669 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001670
Georg Brandlba83f822010-03-14 09:50:54 +00001671- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1672 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001673
Georg Brandlba83f822010-03-14 09:50:54 +00001674- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1675 1e-100 used to raise OverflowError, but now gives the requested 120
1676 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001684
Georg Brandlba83f822010-03-14 09:50:54 +00001685- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1686 decimal string that's guaranteed to round back to x under correct rounding
1687 (with round-half-to-even rounding mode). Previously it gave a string based on
1688 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1689 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1690 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001691
Georg Brandlba83f822010-03-14 09:50:54 +00001692- Issue #7117: On almost all platforms: float-to-string and string-to-float
1693 conversions within Python are now correctly rounded. Places these conversions
1694 occur include: str for floats and complex numbers; the float and complex
1695 constructors; old-style and new-style numeric formatting; serialization and
1696 deserialization of floats and complex numbers using marshal, pickle and json;
1697 parsing of float and imaginary literals in Python code; Decimal-to-float
1698 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001699
Georg Brandlba83f822010-03-14 09:50:54 +00001700 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1701 providing correctly-rounded strtod and dtoa C functions. This code is
1702 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1703 the C compiler. There may be a small number of platforms on which correct
1704 operation of this code cannot be guaranteed, so the code is not used: notably,
1705 this applies to platforms where the C double format is not IEEE 754 binary64,
1706 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1707 and Python's configure script is unable to determine how to change the FPU
1708 precision. On these platforms conversions use the platform strtod and dtoa,
1709 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001710
Georg Brandlba83f822010-03-14 09:50:54 +00001711- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1712 uses the correctly-rounded string <-> float conversions described above (when
1713 available), and so produces correctly rounded results that will display nicely
1714 under the float repr. There are two related small changes: (1) round now
1715 accepts any class with an ``__index__()`` method for its second argument (but
1716 no longer accepts floats for the second argument), and (2) an excessively
1717 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1718 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001860
Georg Brandlba83f822010-03-14 09:50:54 +00001861 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1862 (2) parsing of strings representing infinities and nans was locale aware; and
1863 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00001864
Georg Brandlba83f822010-03-14 09:50:54 +00001865- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1866 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1867 but with at least one decimal point and with a default precision
1868 of 12. Previously, the behavior the same but with a default precision of 6.
1869 This more closely matches ``str()``, and reduces surprises when adding
1870 alignment flags to the empty presentation type. This also affects the new
1871 complex.__format__ in the same way.
1872
1873- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1874 classtype's, even if it was None. property now inserts the __doc__ into the
1875 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00001936 untrackable objects are not tracked by the garbage collector. This can reduce

1945 internal representation of integers, for performance reasons. Base 2**30 is
1946 enabled by default on 64-bit machines. Add --enable-big-digits option to
1947 configure, which overrides the default. Add sys.long_info structseq to

Georg Brandl6425a2f2008-12-28 11:54:53 +00002034- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002035 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002036
Skip Montanarof205c132008-12-23 03:30:15 +00002037- Added test case to ensure attempts to read from a file opened for writing
2038 fail.
2039
Georg Brandlba83f822010-03-14 09:50:54 +00002040- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
2041 elapsed times, not only when some objects are uncollectable/unreachable.
2042 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00002043
Mark Dickinson1a707982008-12-17 16:14:37 +00002044- Issue #3439: Add a bit_length method to int and long.
2045
Georg Brandlba83f822010-03-14 09:50:54 +00002046- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
2047 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00002048
Georg Brandlba83f822010-03-14 09:50:54 +00002049- Issue #4597: Fixed exception handling when the __exit__ function of a context
2050 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00002051
Georg Brandlba83f822010-03-14 09:50:54 +00002052- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00002053
Georg Brandlba83f822010-03-14 09:50:54 +00002054- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2055 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2056 instances. On a typical machine this saves 3 bytes of memory (on average) per
2057 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00002058
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002059- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2060 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2061 instead of throwing a MemoryError.
2062
Georg Brandlba83f822010-03-14 09:50:54 +00002063- Issue #3689: The list reversed iterator now supports __length_hint__ instead
2064 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00002065
Benjamin Petersonc078f922008-11-21 22:27:24 +00002066- Issue #4367: Python would segfault during compiling when the unicodedata
2067 module couldn't be imported and \N escapes were present.
2068
Georg Brandlba83f822010-03-14 09:50:54 +00002069- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2070 file objects with closefd=False. The file descriptor is still kept open but
2071 the file object behaves like a closed file. The ``FileIO`` object also got a
2072 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00002073
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002074- Issue #4348: Some bytearray methods returned that didn't cause any change to
2075 the bytearray, returned the same bytearray instead of a copy.
2076
Georg Brandlba83f822010-03-14 09:50:54 +00002077- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00002078
Benjamin Peterson273c2332008-11-17 22:39:09 +00002079- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
2080
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00002081- Issue #4048: The parser module now correctly validates relative imports.
2082
Benjamin Petersondcee09d2008-10-31 02:16:05 +00002083- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
2084 exec statement.
2085
Georg Brandlba83f822010-03-14 09:50:54 +00002086- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
2087 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00002088
Benjamin Petersonbdca9422008-10-26 20:21:13 +00002089- Issue #4209: Enabling unicode_literals and the print_function in the same
2090 __future__ import didn't work.
2091
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002092- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002093 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002094
Georg Brandlba83f822010-03-14 09:50:54 +00002095- On windows, ``os.chdir()`` given unicode was not working if
2096 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2097 this code path is really executed because I cannot move to such directory on
2098 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002099
Georg Brandlba83f822010-03-14 09:50:54 +00002100- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2101 element is temporarily replaced with an equivalent frozenset. But the
2102 eventual KeyError would always report the empty ``frozenset()`` as the missing
2103 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00002104
Georg Brandlba83f822010-03-14 09:50:54 +00002105- Issue #4509: Various issues surrounding resize of bytearray objects to which
2106 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00002107
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00002108- Issue #4748: Lambda generators no longer return a value.
2109

2111
Gregory P. Smithae91d092009-03-02 05:13:57 +00002112- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
2113
Georg Brandlba83f822010-03-14 09:50:54 +00002114- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
2115 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00002116
Matthias Klose91a3b9e2009-04-05 21:19:13 +00002117- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2118 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00002119
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00002120- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
2121 returned them on 64bit platforms.
2122
Walter Dörwalded960ac2009-05-03 22:36:33 +00002123- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2124 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2125 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2126 of using the replace error handler in PyUnicode_DecodeUTF8().
2127
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002128- Issue #3739: The unicode-internal encoder now reports the number of characters
2129 consumed like any other encoder (instead of the number of bytes).
2130
Georg Brandlba83f822010-03-14 09:50:54 +00002131- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2132 allocator will be automatically disabled when running under Valgrind. This
2133 gives improved memory leak detection when running under Valgrind, while taking
2134 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00002159- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
2160 ownership when the group is not forced, because the group may be different
2161 from the user's group and inherit from its container when the test is run.

2205 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00002206 __main__.py file. This allows applications that run other Python scripts to

3301 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3302 neither __int__ nor __long__, TypeError used to be raised (with a
3303 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and

3500
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003501- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3502 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3503 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3504 ``printf`` function, whereas PyString_FromFormat has an independent
3505 implementation and uses "%zd" on all platforms for size_t values.
3506 This makes a difference on win64, where ``printf`` needs "%Id" to display
3507 64bit values.

3513 object; previously an int would be returned for small values. the __long__
3514 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003524 was correctly parsed but parsing of subsequent arguments failed.
3525
Vinay Sajip35e3b032008-09-01 14:33:59 +00003526- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003527 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3528 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3529 when given a tuple of classes as second argument, were looking up
3530 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3531 type object.
3532

3676-----------------
3677
Guido van Rossumf8402962008-08-20 15:01:50 +00003678- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3679 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3680 extensions do not automatically benefit from the class attribute
3681 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3682 to their tp_flags field if they care. This is a backwards
3683 compatibility feature; in 3.0, all types will use the cache by
3684 default.
3685
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003686- Keyword arguments can now follow starred arguments. (``f(a, *args,

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003692- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3693 by denying s# to parse objects that have a releasebuffer procedure,
3694 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00003696- Issue #3537: Fix an assertion failure when an empty but presized dict
3697 object was stored in the freelist.
3698
Mark Dickinsonb6467572008-08-04 21:30:09 +00003699- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3700 ValueError consistently across platforms.
3701
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003702- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3703 (64bit Unix, for example), unichr() would truncate its argument and return
3704 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3705
Neal Norwitze7d8be82008-07-31 17:17:14 +00003706- Apply security patches from Apple.
3707
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003708- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3709 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3710
Antoine Pitrou92f82162008-07-25 22:22:08 +00003711- Issue #1819: function calls with several named parameters are now on
3712 average 35% faster (as measured by pybench).
3713
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003714- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3715 the python debugger steps into a class statement: the free variables (local
3716 variables defined in an outer scope) would be deleted from the outer scope.
3717
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003718- Issue #2620: Overflow checking when allocating or reallocating memory
3719 was not always being done properly in some python types and extension
3720 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3721 all been updated to perform better checks and places in the code that
3722 would previously leak memory on the error path when such an allocation
3723 failed have been fixed.

3729
Benjamin Petersone977ad42008-08-20 01:42:01 +00003730- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3731 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3732
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003733- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3734 version reported by these tools does not necessarily follow the python
3735 version numbering scheme, so the module is less strict when parsing it.
3736
Nick Coghlanf70385a2008-08-18 12:42:46 +00003737- Issue #2235: Added Py3k warnings for types which will become unhashable
3738 under the stricter __hash__ inheritance rules in 3.0. Several types
3739 which did not meet the rules for hash invariants and were already
3740 unhashable in 3.0 have now been explicitly flagged as unhashable in
3741 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3742 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3743
Brett Cannon88f801d2008-08-18 00:46:22 +00003744- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3773 thread-safe.
3774
Brett Cannonbf3157b2008-08-14 05:00:03 +00003775- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3776 since mimetools itself is deprecated. Because modules are cached, all
3777 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3778
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003779- Issue #3134: shutil referenced undefined WindowsError symbol.

3788 a MemoryError rather than silently stop the iteration.
3789
Guido van Rossum59ce9012008-08-09 14:55:34 +00003790- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3791 to _sre.compile() will now be rejected. This should not affect anybody
3792 since the re.compile() function never generates invalid re-bytecode.
3793
Skip Montanaroa032bf42008-08-08 22:52:51 +00003794- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3795 upon first access it can be automatically initialized from the csv file if
3796 it wasn't initialized during instantiation.
3797
Brett Cannon3aa2a492008-08-06 22:28:09 +00003798- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3799 the reload() built-in has been removed.
3800
Brett Cannon7e30b672008-08-04 21:52:25 +00003801- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003802 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003813 asking for a specific length. This problem only affected files opened
3814 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003815

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003839- Issue #3394: zipfile.writestr sets external attributes when passed a
3840 file name rather than a ZipInfo instance, so files are extracted with
3841 mode 0600 rather than 000 under Unix.
3842
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003843- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3844 argument in python 2.5, this broke code that subclassed Popen to include its
3845 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003855- Issue #2235: the C API function PyObject_HashNotImplemented and its
3856 interaction with the tp_hash slot (added in 2.6b2) are now documented
3857
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003858- Issue #643841: The language reference now provides more detailed
3859 coverage of the lookup process for special methods. The disclaimers
3860 regarding lack of coverage of new-style classes have also been
3861 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003869Core and Builtins
3870-----------------
3871
Georg Brandl3e483f62008-07-16 22:57:41 +00003872- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3873 its methods now allow for items objects that can be converted to
3874 an integer using operator.index().
3875
Mark Dickinson64b7e502008-07-16 09:40:03 +00003876- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3877 produced a ValueError instead of giving the correct float.
3878
Eric Smitha5fa5a22008-07-16 00:11:49 +00003879- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3880 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3881
Mark Dickinson7103aa42008-07-15 19:08:33 +00003882- Issue #3008: the float type has a new instance method 'float.hex'
3883 and a new class method 'float.fromhex' to convert floating-point
3884 numbers to and from hexadecimal strings, respectively.
3885
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003886- Issue #2235: __hash__ is once again inherited by default. To allow
3887 collections.Hashable to remain meaningful in the presence of the
3888 default hash implementation (object.__hash__), it is now possible
3889 to explicit block inheritance of hash by setting __hash__=None at
3890 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3891 level.
3892
Nick Coghlanb028f502008-07-13 14:52:36 +00003893- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3894 the parent module cannot be found while performing an absolute import.
3895 This means that an incorrectly defined __package__ attribute will
3896 now only prevent relative imports in that module rather than causing
3897 all imports from that module to fail.
3898
Nick Coghlan14ff9942008-07-08 14:21:42 +00003899- Issue #2517: Allow unicode messages in Exceptions again by correctly
3900 bypassing the instance dictionary when looking up __unicode__ on
3901 new-style classes.
3902
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003903- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3904 set to a custom object whose write() method happens to install
3905 another file in sys.stdout.
3906
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003907- Issue #3088: Corrected a race condition in classes derived from
3908 threading.local: the first member set by a thread could be saved in
3909 another thread's dictionary.
3910
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003911- Issue #3004: Minor change to slice.indices(): the start and stop
3912 arguments are now treated identically, making the behaviour easier
3913 to describe and understand. For example, slice(None, -10,
3914 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3915 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3916 10, -1).
3917
Georg Brandl278fc502008-07-19 12:46:12 +00003918- Issue #3219: Calling a function with repeated keyword arguments,
3919 f(a=2, a=23), would not cause a syntax error. This was a regression
3920 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003921
Georg Brandl278fc502008-07-19 12:46:12 +00003922- Issue #2862: Make int and float freelist management consistent with
3923 other freelists. Changes their CompactFreeList apis into
3924 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003925

3927-------
3928
Thomas Heller57adf222008-08-14 19:10:48 +00003929- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3930 api functions without holding the GIL, which could lead to a fatal
3931 error when they failed.
3932
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003933- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3942 ForkingPickler.register() to resolve conflict with ctypes.
3943
Vinay Sajip51e65192008-07-18 09:01:10 +00003944- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003946- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3947 a valid dlerror() message.
3948
Thomas Heller2bad6572008-07-15 17:19:50 +00003949- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3950 incomplete structure was created.
3951
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003952- Issue #3339: dummy_thread.acquire() should not return None.

3955
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003956- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003957
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003958- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3959 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003960 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003961 content-length. The problem had been corrected in the 2.4 branch, but never
3962 merged into trunk.
3963
Georg Brandle78fbcc2008-07-05 10:13:36 +00003964- Issue #2663: add filtering capability to shutil.copytree().

4367
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004368- On MacOS X it is now possible to install the framework in 64-bit
4369 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004370 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004371
4372 This is controlled by the configure argument ``--with-universal-archs``:
4373
4374 - ``--with-universal-archs=all``: install 4-way universal
4375
4376 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4377
4378 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4379
4380 This option should be used in combination with ``--enable-universalsdk=``.
4381
4382 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 +00004432- Issue #1631171: Re-implement the 'warnings' module in C (the
4433 original Python code has been kept as backup). This will allow for
4434 using the 'warning's machinery in such places as the parser where
4435 use of pure Python code is not possible. Both the ``showarning()``
4436 and ``formatwarning()`` gain an optional 'line' argument which is
4437 not called by default for backwards-compatibility reasons. Setting
4438 ``warnings.showwarning()`` to an implementation that lacks support
4439 for the ``line`` argument will raise a DeprecationWarning.

4463
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004464- The getpass module has been improved on Unix. It now uses /dev/tty
4465 by default and uses stderr instead of stdout. A GetPassWarning is
4466 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004502- Issue #2550: The approach used by client/server code for obtaining
4503 ports to listen on in network-oriented tests has been refined in an
4504 effort to facilitate running multiple instances of the entire
4505 regression test suite in parallel without issue.
4506 test_support.bind_port() has been fixed such that it will always
4507 return a unique port -- which wasn't always the case with the
4508 previous implementation, especially if socket options had been set
4509 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4510 new implementation of bind_port() will actually raise an exception
4511 if it is passed an AF_INET/SOCK_STREAM socket with either the
4512 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4513 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4514 the socket it's been passed. This currently only applies to
4515 Windows. This option prevents any other sockets from binding to the
4516 host/port we've bound to, thus removing the possibility of the
4517 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4518 when a second SOCK_STREAM socket binds and accepts to a host/port
4519 that's already been bound by another socket. The optional preferred
4520 port parameter to bind_port() has been removed. Under no
4521 circumstances should tests be hard coding ports!
4522
4523 test_support.find_unused_port() has also been introduced, which will
4524 pass a temporary socket object to bind_port() in order to obtain an
4525 unused port. The temporary socket object is then closed and
4526 deleted, and the port is returned. This method should only be used
4527 for obtaining an unused port in order to pass to an external program
4528 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4529 a parameter to a server-oriented class that doesn't give you direct
4530 access to the underlying socket used.
4531
4532 Finally, test_support.HOST has been introduced, which should be used
4533 for the host argument of any relevant socket calls (i.e. bind and
4534 connect).

4809-----------------
4810
Fred Drakea8ee94b2008-03-01 02:45:07 +00004811- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004812 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004813
Georg Brandlad61bc82008-02-23 15:11:18 +00004814- Issue #2067: file.__exit__() now calls subclasses' close() method.
4815
4816- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004817
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004818- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00004819 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00004820
Eric Smitha73fbe72008-02-23 03:09:44 +00004821- Added the future_builtins module, which contains hex() and oct().
4822 These are the PEP 3127 version of these functions, designed to be
4823 compatible with the hex() and oct() builtins from Python 3.0. They
4824 differ slightly in their output formats from the existing, unchanged
4825 Python 2.6 builtins. The expected usage of the future_builtins
4826 module is:
4827 from future_builtins import hex, oct
4828
Eric Smith7ef40bf2008-02-20 23:34:22 +00004829- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4830 exponents for exponents with absolute value < 100. Follows C99
4831 standard. This is a change on Windows, which would use 3 digits.
4832 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4833 so that any alterations it does to the resulting string will be
4834 available in stringlib/formatter.h (for float.__format__).
4835
Eric Smith5a3c1352008-02-19 13:21:56 +00004836- Implemented PEP 3101, Advanced String Formatting. This adds a new
4837 builtin format(); a format() method for str and unicode; a
4838 __format__() method to object, str, unicode, int, long, float, and
4839 datetime; the class string.Formatter; and the C API
4840 PyObject_Format().
4841
Georg Brandl3ee81df2008-05-17 18:14:43 +00004842- Fixed several potential crashes, all caused by specially crafted
4843 __del__ methods exploiting objects in temporarily inconsistent
4844 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004845
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004846- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004847 prevent a possible crash: an Abstract Base Class would try to access
4848 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004849
Georg Brandl3ee81df2008-05-17 18:14:43 +00004850- Fixed repr() and str() of complex numbers with infinity or nan as
4851 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004852
Georg Brandl3ee81df2008-05-17 18:14:43 +00004853- Clear all free lists during a gc.collect() of the highest generation
4854 in order to allow pymalloc to free more arenas. Python may give back
4855 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004856
Georg Brandl3ee81df2008-05-17 18:14:43 +00004857- Issue #2045: Fix an infinite recursion triggered when printing a
4858 subclass of collections.defaultdict, if its default_factory is set
4859 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004860
Christian Heimesf75dbef2008-02-08 00:11:31 +00004861- Fixed a minor memory leak in dictobject.c. The content of the free
4862 list was not freed on interpreter shutdown.
4863
Georg Brandl21e99f42010-03-07 15:23:59 +00004864- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004865 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004866
Georg Brandl3ee81df2008-05-17 18:14:43 +00004867- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4868 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004869 to compact the internal free lists of pre-allocted ints and floats.
4870
Georg Brandl3ee81df2008-05-17 18:14:43 +00004871- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4872 calls. Python expected the return type int but the fork familie
4873 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004874
Georg Brandl3ee81df2008-05-17 18:14:43 +00004875- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4876 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004877
Georg Brandl3ee81df2008-05-17 18:14:43 +00004878- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4879 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004880
Georg Brandl3ee81df2008-05-17 18:14:43 +00004881- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4882 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004883
Georg Brandl3ee81df2008-05-17 18:14:43 +00004884- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4885 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004886
Georg Brandl3ee81df2008-05-17 18:14:43 +00004887- Patch #1473257: generator objects gain a gi_code attribute. This is
4888 the same object as the func_code attribute of the function that
4889 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004890
Georg Brandl3ee81df2008-05-17 18:14:43 +00004891- Issue #1920: "while 0" statements were completely removed by the
4892 compiler, even in the presence of an "else" clause, which is
4893 supposed to be run when the condition is false. Now the compiler
4894 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004895
Guido van Rossumeead05f2008-01-24 18:21:02 +00004896- A few crashers fixed: weakref_in_del.py (issue #1377858);
4897 loosing_dict_ref.py (issue #1303614, test67.py);
4898 borrowed_ref_[34].py (not in tracker).
4899
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004900- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004901 suppressed while an extension is loaded by calling SetErrorMode in
4902 dynload_win.c. The error is still reported properly.
4903
Georg Brandl3ee81df2008-05-17 18:14:43 +00004904- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004905 several extension methods and modules do not work without unicode
4906 support.
4907
Georg Brandl26543b12008-01-21 18:36:51 +00004908- Issue #1882: when compiling code from a string, encoding cookies in the
4909 second line of code were not always recognized correctly.
4910
Georg Brandl14404b62008-01-19 19:27:05 +00004911- Issue #1679: "0x" was taken as a valid integer literal.
4912
Georg Brandl6caad7d2008-01-26 14:19:22 +00004913- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004914 added.
4915
Christian Heimesc94e2b52008-01-14 04:13:37 +00004916- sys.float_info / PyFloat_GetInfo: The floating point information
4917 object was converted from a dict to a specialized structseq object.
4918
Georg Brandl3ee81df2008-05-17 18:14:43 +00004919- Patch #1816: Added sys.flags structseq. It exposes the status of
4920 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004921
Georg Brandl3ee81df2008-05-17 18:14:43 +00004922- Objects/structseq.c: Implemented new structseq representation. The
4923 patch makes structseqs (e.g. the return value of os.stat) more
4924 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004925
Georg Brandl3ee81df2008-05-17 18:14:43 +00004926- Patch #1700288: added a type attribute cache that caches method
4927 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004928
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004929- Bug #1776: __import__() no longer accepts filenames on any platform.
4930 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004931
Georg Brandlaed6c662008-01-07 17:25:53 +00004932- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4933
Georg Brandl3ee81df2008-05-17 18:14:43 +00004934- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4935 envvar and sys.dont_write_bytecode attribute. All these can be set
4936 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004937
Georg Brandl3ee81df2008-05-17 18:14:43 +00004938- Improve some exception messages when Windows fails to load an
4939 extension module. Now we get for example '%1 is not a valid Win32
4940 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004941
Georg Brandl3ee81df2008-05-17 18:14:43 +00004942- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004944- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4945 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004946
Christian Heimes0a8143f2007-12-18 23:22:54 +00004947- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004948 and INF. float("nan"), float("inf") and float("-inf") now work on
4949 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004950
Georg Brandl3ee81df2008-05-17 18:14:43 +00004951- Compiler now generates simpler and faster code for dictionary
4952 literals. The oparg for BUILD_MAP now indicates an estimated
4953 dictionary size. There is a new opcode, STORE_MAP, for adding
4954 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004955
Georg Brandl3ee81df2008-05-17 18:14:43 +00004956- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004961- Issue #1538: Avoid copying string in split/rsplit if the split char
4962 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004963
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004964- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004965 SystemError.
4966
Nick Coghlanef01d822007-12-03 12:55:17 +00004967- PEP 366: Allow explicit relative imports when executing modules
4968 inside packages with the -m switch via a new module level
4969 __package__ attribute.
4970
Georg Brandl3ee81df2008-05-17 18:14:43 +00004971- Issue #1402: Fix a crash on exit, when another thread is still
4972 running, and if the deallocation of its frames somehow calls the
4973 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004974

4984 file can now be directly executed by passing their name to the
4985 interpreter. The directory/zipfile is automatically inserted as the
4986 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004987
Georg Brandl3ee81df2008-05-17 18:14:43 +00004988- Issue #1265: Fix a problem with sys.settrace, if the tracing
4989 function uses a generator expression when at the same time the
4990 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004991
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004992- sets and frozensets now have an isdisjoint() method.
4993
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004994- optimize the performance of builtin.sum().
4995
Neal Norwitz44f326e2007-10-05 05:29:17 +00004996- Fix warnings found by the new version of the Coverity checker.
4997
Georg Brandl21e99f42010-03-07 15:23:59 +00004998- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004999 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5000 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005001
Georg Brandl3ee81df2008-05-17 18:14:43 +00005002- Issue #1686386: Tuple's tp_repr did not take into account the
5003 possibility of having a self-referential tuple, which is possible
5004 from C code. Nor did object's tp_str consider that a type's tp_str
5005 could do something that could lead to an inifinite recursion.
5006 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5007 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005008
Georg Brandl3ee81df2008-05-17 18:14:43 +00005009- Issue #1164: It was possible to trigger deadlock when using the
5010 'print' statement to write to a file since the GIL was not released
5011 as needed. Now PyObject_Print() does the right thing along with
5012 various tp_print implementations of the built-in types and those in
5013 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005014
Georg Brandl3ee81df2008-05-17 18:14:43 +00005015- Issue #1147: Exceptions were directly allowing string exceptions in
5016 their throw() method even though string exceptions no longer
5017 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005018

Brett Cannon1e534b52007-09-07 04:18:30 +00005022- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005023 PyObject_Call() never calling back out to Python code to trigger
5024 recursion depth updates/checks. Required the creation of a static
5025 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005043 __*__ attributes. (Some already existed, e.g., __doc__ and
5044 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005045

5054 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005062 setting a plain string, ie don't expand to single letter identifiers.
5063
Raymond Hettinger13936692007-04-11 18:40:58 +00005064- Request #1191699: Slices can now be pickled.

5074
Guido van Rossum143b5642007-03-23 04:58:42 +00005075- Bug #1683368: The object.__init__() and object.__new__() methods are
5076 now stricter in rejecting excess arguments. The only time when
5077 either allows excess arguments is when it is not overridden and the
5078 other one is. For backwards compatibility, when both are
5079 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005080 warning later). Also, type.__init__() insists on the same signature
5081 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005082
Georg Brandl3ee81df2008-05-17 18:14:43 +00005083- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5084 object to complex using its __complex__() method before falling back
5085 to the __float__() method. Therefore, the functions in the cmath
5086 module now can operate on objects that define a __complex__()
5087 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005105- Bug #1678647: write a newline after printing an exception in any
5106 case, even when converting the value to a string failed.
5107
Georg Brandl871f1bc2007-03-12 13:17:36 +00005108- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005109 its argument, if it exists. If not, it will work like before. This
5110 allows customizing the output of dir() in the presence of a
5111 __getattr__().

5121 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00005123- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124 makes the filenames the warning module prints much more sensible
5125 when a PYTHONSTARTUP file is used.

5139 sq_ass_slice instead of the sq_slice slot.
5140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- When printing an unraisable error, don't print exceptions. before

5769 accepted in TestSuite.addTest(). This should cause no
5770 incompatibility since it never made sense with ordinary subclasses
5771 -- the failure just occurred later, with a more cumbersome
5772 exception.

6056 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006057
Georg Brandl3ee81df2008-05-17 18:14:43 +00006058- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006059 that the SMTP.starttls() caller no longer needs to call ehlo()
6060 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006061 does not claim to support starttls. Adds the
6062 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00006161 time so that opening a database previously created with the DB_DUP
6162 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6163 opens. Specifically: dictionary assignment to a DB object will
6164 replace all values for a given key when the database allows
6165 duplicate values. DB users should use DB.put(k, v) when they want
6166 to store duplicates; not DB[k] = v.

6173 characters with ASCII value less than 32. Also, it correctly quotes
6174 dots only if they occur on a single line, as opposed to the previous
6175 behavior of quoting dots if they are the second character of any
6176 line.

6499-----
6500
Georg Brandl3ee81df2008-05-17 18:14:43 +00006501- Unified naming convention for free lists and their limits. All free
6502 lists in Object/ are named ``free_list``, the counter ``numfree``
6503 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6504 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006505
Georg Brandl3ee81df2008-05-17 18:14:43 +00006506- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6507 to ``PyTuple_SetItem``, it can be used to populate a brand new
6508 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006509
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006510- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006511
Georg Brandl3ee81df2008-05-17 18:14:43 +00006512- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6513 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6514 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006515
6516- Patch #1720595: add T_BOOL to the range of structmember types.
6517
6518- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6519 ``PyFloat_GetInfo()`` to the float API.
6520
Georg Brandl3ee81df2008-05-17 18:14:43 +00006521- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6522 of w# format code incorrectly truncated the length to an int, even
6523 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6524 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006525
Georg Brandl3ee81df2008-05-17 18:14:43 +00006526- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6527 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006528
Georg Brandl3ee81df2008-05-17 18:14:43 +00006529- PEP 3123: Provide forward compatibility with Python 3.0, while
6530 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6531 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006532
Georg Brandl3ee81df2008-05-17 18:14:43 +00006533- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6534 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006535
6536- Patch #1733960: Allow T_LONGLONG to accept ints.
6537
6538- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6539
Christian Heimes000a0742008-01-03 22:16:32 +00006540- Added a new API function ``PyImport_ImportModuleNoBlock``.
6541
Georg Brandl6caad7d2008-01-26 14:19:22 +00006542- Bug #1637022: Prefix AST symbols with _Py_.
6543
6544- Fix some leftovers from the conversion from int to Py_ssize_t
6545 (relevant to strings and sequences of more than 2**31 items).
6546
6547- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6548 outside of pystate.c and should not be necessary.
6549
Georg Brandl3ee81df2008-05-17 18:14:43 +00006550- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6551 absolute imports. In earlier versions they might have used relative
6552 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006553
Georg Brandl3ee81df2008-05-17 18:14:43 +00006554- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6555 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006556
Georg Brandl3ee81df2008-05-17 18:14:43 +00006557- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6558 macro so it can be used as an expression.

6563
Georg Brandl3ee81df2008-05-17 18:14:43 +00006564- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6565 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6566 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6567 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006568
Georg Brandl3ee81df2008-05-17 18:14:43 +00006569- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
6570 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006582- Removed the macfs module. It had been deprecated since Python 2.5.
6583 This lead to the deprecation of macostools.touched() as it relied
6584 solely on macfs and was a no-op under OS X.
