Antoine Pitrou0a7b65b2010-09-08 12:40:49 +000015- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
16 thread-local storage key.
17
Victor Stinnercaafd772010-09-08 10:51:01 +000018- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
19 encoding and errors attributes instead of using utf-8 in strict mode, to get
20 the same behaviour than the print statement.
21
Antoine Pitrou9cf85f12010-09-01 21:17:34 +000022- Issue #9737: Fix a crash when trying to delete a slice or an item from
23 a memoryview object.
24
Martin v. Löwis6086b0d2010-08-19 09:09:04 +000025- Restore GIL in nis_cat in case of error.
26

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

47
Vinay Sajip546885e2010-09-25 17:42:36 +000048- Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler.
49
Alexander Belopolsky517185e2010-09-24 18:14:18 +000050- Issue #9936: Fixed executable lines' search in the trace module.
51
Antoine Pitrou2c7d6852010-09-23 19:55:24 +000052- Issue #9928: Properly initialize the types exported by the bz2 module.
53
Antoine Pitrou6391b342010-09-14 18:48:19 +000054- Issue #9854: The default read() implementation in io.RawIOBase now
55 handles non-blocking readinto() returning None correctly.
56
Antoine Pitrouf7f390a2010-09-14 14:37:18 +000057- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
58 SSLSocket.sendto() to match the corresponding socket methods. Also,
59 fix various SSLSocket methods to raise socket.error rather than an
60 unhelpful TypeError when called on an unconnected socket. Original patch
61 by Andrew Bennetts.
62
Raymond Hettinger74f869e2010-09-13 22:14:36 +000063- Issue #9826: OrderedDict.__repr__ can now handle self-referential
64 values: d['x'] = d.

Antoine Pitroue4195e82010-09-12 14:56:27 +000068- Issue #9837: The read() method of ZipExtFile objects (as returned by
69 ZipFile.open()) could return more bytes than requested.
70
Raymond Hettinger20397532010-09-12 02:11:45 +000071- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
72 This prevents user-created self-referencing ordered dictionaries from
73 becoming permanently uncollectable GC garbage. The downside is that
74 removing __del__ means that the internal doubly-linked list has to wait for
75 GC collection rather than freeing memory immediately when the refcnt drops
76 to zero.
77
Raymond Hettingerffd2a422010-09-10 10:47:22 +000078- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
79 different internal state for small values of n. Fixed by salting the
80 value.
81
Antoine Pitrouc818ed42010-09-07 21:40:25 +000082- Issue #9792: In case of connection failure, socket.create_connection()
83 would swallow the exception and raise a new one, making it impossible
84 to fetch the original errno, or to filter timeout errors. Now the
85 original error is re-raised.
86
Antoine Pitrouf4f61712010-09-07 16:34:47 +000087- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
88 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
89 be updated back after the system call. Original patch by Brian Brazil.
90
Antoine Pitroudca9de92010-09-04 17:52:26 +000091- Issue #1100562: Fix deep-copying of objects derived from the list and
92 dict types. Patch by Michele Orrù and Björn Lindqvist.
93
Fred Drakea1e627d2010-09-03 03:55:50 +000094- Issue #7005: Fixed output of None values for RawConfigParser.write and
95 ConfigParser.write.
96
Daniel Stutzbach66c981b2010-08-31 20:29:39 +000097- Issue #808164: Fixed socket.close to avoid references to globals, to
98 avoid issues when socket.close is called from a __del__ method.
99
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000100- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
101 falling into recursion.
102
R. David Murray7c4bf552010-08-25 01:45:57 +0000103- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
104 character years even if the message contains RFC822 two character years.
105
Daniel Stutzbach91287322010-08-24 21:09:30 +0000106- Issue #8750: Fixed MutableSet's methods to correctly handle
107 reflexive operations, namely x -= x and x ^= x.
108
Victor Stinnercaafd772010-09-08 10:51:01 +0000109- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000110 error handling when accepting a new connection.
111
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000112- Issue #658749: asyncore's connect() method now correctly interprets winsock
113 errors.
114

118 module now correctly return a set. (Patch by Eli Bendersky.)
119
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000120- Issue #9617: Signals received during a low-level write operation aren't
121 ignored by the buffered IO layer anymore.
122
Benjamin Peterson52c36052010-08-21 03:03:22 +0000123- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
124 are not held onto after they are deleted elsewhere.
125
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000126- Issue #9626: the view methods for collections.OrderedDict() were returning
127 the unordered versions inherited from dict. Those methods are now
128 overridden to provide ordered views.
129
Éric Araujo0389ae62010-08-14 03:07:46 +0000130- Issue #8688: MANIFEST files created by distutils now include a magic
131 comment indicating they are generated. Manually maintained MANIFESTs
132 without this marker will not be overwritten or removed.
133
Antoine Pitroue1436d12010-08-12 15:25:51 +0000134- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
135 and a BadZipfile error is raised if it doesn't match (as used to be the
136 case in Python 2.5 and earlier).
137
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000138- Issue #9550: a BufferedReader could issue an additional read when the

141 patch by Jason V. Miller.
142
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000143- Issue #9551: Don't raise TypeError when setting the value to None for

147 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
148
Antoine Pitrou99009162010-08-09 22:51:24 +0000149- Issue #3757: thread-local objects now support cyclic garbage collection.
150 Thread-local objects involved in reference cycles will be deallocated
151 timely by the cyclic GC, even if the underlying thread is still running.
152
Florent Xicluna2f1b1ff2010-08-09 20:46:49 +0000153- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the

162 This is how it is supposed to work, wget and curl do the same. Previous
163 behavior was wrong.
164
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +0000165- Issue #2944: asyncore doesn't handle connection refused correctly.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000503- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
504 start byte and the continuation byte(s) are now considered invalid, instead
505 of the number of bytes specified by the start byte.
506 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
507 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
508 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

519 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000863- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000864 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
865 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
866 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Petersonfbac6c12010-04-10 16:22:05 +0000884*Release date: 2010-04-10*
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000885
886Core and Builtins
887-----------------
888
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000889- Issue #7301: Add environment variable $PYTHONWARNINGS.
890
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000891- Issue #8329: Don't return the same lists from select.select when no fds are
892 changed.
893
Georg Brandlfee0f442010-05-22 21:26:21 +0000894- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000895 on 64-bit machines. The shift count for either left or right shift is
896 permitted to be up to sys.maxsize.
897
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000898- Ensure that tokenization of identifiers is not affected by locale.
899
Georg Brandlfee0f442010-05-22 21:26:21 +0000900- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000901
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000902- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
903
Georg Brandlfee0f442010-05-22 21:26:21 +0000904- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
905 with a non-empty format string. This is an effort to future-proof user
906 code. If a derived class does not currently implement __format__ but later
907 adds its own __format__, it would most likely break user code that had
908 supplied a format string. This will be changed to a DeprecationWaring in
909 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000910
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000911- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner95affc42010-03-22 12:24:37 +0000918
Benjamin Peterson96545892010-03-21 20:21:00 +0000919- Issue #6474: Make error message from passing an inadequate number of keyword

935
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000936- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000937 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
938 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000939
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000940- Issue #8310: Allow dis to examine new style classes.
941
Georg Brandlfee0f442010-05-22 21:26:21 +0000942- Issue #8257: The Decimal construct now accepts a float instance directly,
943 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000944
945 >>> Decimal(1.1)
946 Decimal('1.100000000000000088817841970012523233890533447265625')
947
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000948- collections.Counter() now supports a subtract() method.
949
Georg Brandlfee0f442010-05-22 21:26:21 +0000950- The functools module now has a total_ordering() class decorator to simplify
951 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000952
Georg Brandlfee0f442010-05-22 21:26:21 +0000953- The functools module also adds cmp_to_key() as a tool to transition old-style
954 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000955
Georg Brandlfee0f442010-05-22 21:26:21 +0000956- Issue #8294: The Fraction constructor now accepts Decimal and float instances
957 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000958
Georg Brandlfee0f442010-05-22 21:26:21 +0000959- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
960 InvalidOperation instead of returning False. (Comparisons involving a quiet
961 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
962 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000963
Georg Brandlfee0f442010-05-22 21:26:21 +0000964- Issue #2531: Comparison operations between floats and Decimal instances now
965 return a result based on the numeric values of the operands; previously they
966 returned an arbitrary result based on the relative ordering of id(float) and
967 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000968
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000969- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000970 argument `-` which tells it to read files to compile from stdin. Each line is
971 read on demand and the named file is compiled immediately. (Original patch by
972 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000973
Georg Brandlfee0f442010-05-22 21:26:21 +0000974- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000977- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
978 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000979 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000980
Georg Brandlfee0f442010-05-22 21:26:21 +0000981- Comparisons using one of <, <=, >, >= between a complex instance and a
982 Fractions instance now raise TypeError instead of returning True/False. This
983 makes Fraction <=> complex comparisons consistent with int <=> complex, float
984 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000985
Michael Foorde6410c52010-03-29 20:04:23 +0000986- Addition of ``WeakSet`` to the ``weakref`` module.

994
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000995- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000996 didn't support chflags() (for example ZFS under FreeBSD). The error is now
997 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000998
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000999- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1000 deprecated.
1001
Georg Brandlfee0f442010-05-22 21:26:21 +00001002- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1003 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001004

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001039- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001040 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1041 log file to compute the next rollover time. If the log file does not exist,
1042 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001043
Georg Brandlba83f822010-03-14 09:50:54 +00001044- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001052- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1053 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1054 This is a behavior change, so email's minor version number is now bumped, to
1055 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001083- Issue #8300: When passing a non-integer argument to struct.pack with any
1084 integer format code, struct.pack first attempts to convert the non-integer
1085 using its __index__ method. If that method is non-existent or raises

1087
Georg Brandlba83f822010-03-14 09:50:54 +00001088- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1089 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1090 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001091 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1092 inconsistent: __int__ was used for some integer codes but not for others, and
1093 the set of integer codes for which it was used differed between native packing
1094 and standard packing.)

1495-----------------
1496
Georg Brandlba83f822010-03-14 09:50:54 +00001497- The ``__complex__()`` method is now looked up on the class of instances to
1498 make it consistent with other special methods.

1502
Mark Dickinson1b34d252010-01-01 17:27:30 +00001503- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001504 DeprecationWarning when passed a float argument where an integer was expected.
1505 These functions and methods now raise TypeError instead. The majority of the
1506 effects of this change are in the extension modules, but some core functions
1507 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1508 and many unicode/str methods.

1522 of integers: the result of a/b is now correctly rounded for ints a and b (at
1523 least on IEEE 754 platforms), and in particular does not depend on the
1524 internal representation of a long.

1532
Georg Brandlba83f822010-03-14 09:50:54 +00001533 These executables now work properly with the arch(1) command: ``arch -ppc
1534 python`` will start a universal binary version of python in PPC mode (unlike

1675 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001676
Georg Brandlba83f822010-03-14 09:50:54 +00001677- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1678 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001679
Georg Brandlba83f822010-03-14 09:50:54 +00001680- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001690
Georg Brandlba83f822010-03-14 09:50:54 +00001691- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1692 decimal string that's guaranteed to round back to x under correct rounding
1693 (with round-half-to-even rounding mode). Previously it gave a string based on
1694 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1695 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1696 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001697
Georg Brandlba83f822010-03-14 09:50:54 +00001698- Issue #7117: On almost all platforms: float-to-string and string-to-float
1699 conversions within Python are now correctly rounded. Places these conversions
1700 occur include: str for floats and complex numbers; the float and complex
1701 constructors; old-style and new-style numeric formatting; serialization and
1702 deserialization of floats and complex numbers using marshal, pickle and json;
1703 parsing of float and imaginary literals in Python code; Decimal-to-float
1704 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001705
Georg Brandlba83f822010-03-14 09:50:54 +00001706 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1707 providing correctly-rounded strtod and dtoa C functions. This code is
1708 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1709 the C compiler. There may be a small number of platforms on which correct
1710 operation of this code cannot be guaranteed, so the code is not used: notably,
1711 this applies to platforms where the C double format is not IEEE 754 binary64,
1712 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1713 and Python's configure script is unable to determine how to change the FPU
1714 precision. On these platforms conversions use the platform strtod and dtoa,
1715 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001716
Georg Brandlba83f822010-03-14 09:50:54 +00001717- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1718 uses the correctly-rounded string <-> float conversions described above (when
1719 available), and so produces correctly rounded results that will display nicely
1720 under the float repr. There are two related small changes: (1) round now
1721 accepts any class with an ``__index__()`` method for its second argument (but
1722 no longer accepts floats for the second argument), and (2) an excessively
1723 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1724 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001867 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1868 (2) parsing of strings representing infinities and nans was locale aware; and
1869 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001871- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1872 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1873 but with at least one decimal point and with a default precision
1874 of 12. Previously, the behavior the same but with a default precision of 6.
1875 This more closely matches ``str()``, and reduces surprises when adding
1876 alignment flags to the empty presentation type. This also affects the new
1877 complex.__format__ in the same way.
1878
1879- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Benjamin Petersonfe231b02008-12-29 17:47:42 +00002037- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
2038 systems.
2039
Georg Brandl6425a2f2008-12-28 11:54:53 +00002040- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002041 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002042
Skip Montanarof205c132008-12-23 03:30:15 +00002043- Added test case to ensure attempts to read from a file opened for writing
2044 fail.
2045
Georg Brandlba83f822010-03-14 09:50:54 +00002046- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print

Georg Brandlba83f822010-03-14 09:50:54 +00002060- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2061 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2062 instances. On a typical machine this saves 3 bytes of memory (on average) per
2063 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002065- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2066 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2067 instead of throwing a MemoryError.
2068
Georg Brandlba83f822010-03-14 09:50:54 +00002069- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00002072- Issue #4367: Python would segfault during compiling when the unicodedata
2073 module couldn't be imported and \N escapes were present.
2074
Georg Brandlba83f822010-03-14 09:50:54 +00002075- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2076 file objects with closefd=False. The file descriptor is still kept open but
2077 the file object behaves like a closed file. The ``FileIO`` object also got a
2078 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002080- Issue #4348: Some bytearray methods returned that didn't cause any change to
2081 the bytearray, returned the same bytearray instead of a copy.
2082
Georg Brandlba83f822010-03-14 09:50:54 +00002083- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersondcee09d2008-10-31 02:16:05 +00002089- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

Benjamin Petersonbdca9422008-10-26 20:21:13 +00002095- Issue #4209: Enabling unicode_literals and the print_function in the same
2096 __future__ import didn't work.
2097
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002098- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002099 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002100
Georg Brandlba83f822010-03-14 09:50:54 +00002101- On windows, ``os.chdir()`` given unicode was not working if
2102 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2103 this code path is really executed because I cannot move to such directory on
2104 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002105
Georg Brandlba83f822010-03-14 09:50:54 +00002106- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2107 element is temporarily replaced with an equivalent frozenset. But the
2108 eventual KeyError would always report the empty ``frozenset()`` as the missing
2109 key. Now it correctly refers to the initial element.

2127 returned them on 64bit platforms.
2128
Walter Dörwalded960ac2009-05-03 22:36:33 +00002129- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2130 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2131 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2132 of using the replace error handler in PyUnicode_DecodeUTF8().
2133
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002134- Issue #3739: The unicode-internal encoder now reports the number of characters

2136
Georg Brandlba83f822010-03-14 09:50:54 +00002137- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2138 allocator will be automatically disabled when running under Valgrind. This
2139 gives improved memory leak detection when running under Valgrind, while taking
2140 advantage of pymalloc at other times.

3403 should cause a test to be skipped are now done using import_module from test
3404 support, which does the conversion.

3506
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003507- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3508 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3509 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3510 ``printf`` function, whereas PyString_FromFormat has an independent
3511 implementation and uses "%zd" on all platforms for size_t values.
3512 This makes a difference on win64, where ``printf`` needs "%Id" to display
3513 64bit values.

3519 object; previously an int would be returned for small values. the __long__
3520 method is allowed to return either an int or a long, but the behaviour of
3521 float objects should not change to respect backward compatibility.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003529 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003530 was correctly parsed but parsing of subsequent arguments failed.
3531
Vinay Sajip35e3b032008-09-01 14:33:59 +00003532- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003533 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3534 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3535 when given a tuple of classes as second argument, were looking up
3536 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3537 type object.
3538
Neal Norwitz18aa3882008-08-24 05:04:52 +00003539- Fix crashes on memory allocation failure found with failmalloc.

3682-----------------
3683
Guido van Rossumf8402962008-08-20 15:01:50 +00003684- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3685 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3686 extensions do not automatically benefit from the class attribute
3687 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3688 to their tp_flags field if they care. This is a backwards
3689 compatibility feature; in 3.0, all types will use the cache by
3690 default.
3691
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003692- Keyword arguments can now follow starred arguments. (``f(a, *args,
3693 keyword=23)`` is now valid syntax.)
3694
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003695- ctypes function pointers that are COM methods have a boolean True

Mark Dickinsonb6467572008-08-04 21:30:09 +00003705- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3706 ValueError consistently across platforms.
3707
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003708- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3709 (64bit Unix, for example), unichr() would truncate its argument and return
3710 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3711
Neal Norwitze7d8be82008-07-31 17:17:14 +00003712- Apply security patches from Apple.

3715 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3716
Antoine Pitrou92f82162008-07-25 22:22:08 +00003717- Issue #1819: function calls with several named parameters are now on

3721 the python debugger steps into a class statement: the free variables (local
3722 variables defined in an outer scope) would be deleted from the outer scope.
3723
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003724- Issue #2620: Overflow checking when allocating or reallocating memory
3725 was not always being done properly in some python types and extension
3726 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3727 all been updated to perform better checks and places in the code that
3728 would previously leak memory on the error path when such an allocation
3729 failed have been fixed.

3737 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3738
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003739- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3740 version reported by these tools does not necessarily follow the python
3741 version numbering scheme, so the module is less strict when parsing it.
3742
Nick Coghlanf70385a2008-08-18 12:42:46 +00003743- Issue #2235: Added Py3k warnings for types which will become unhashable
3744 under the stricter __hash__ inheritance rules in 3.0. Several types
3745 which did not meet the rules for hash invariants and were already
3746 unhashable in 3.0 have now been explicitly flagged as unhashable in
3747 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,

Brett Cannonbf3157b2008-08-14 05:00:03 +00003781- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3782 since mimetools itself is deprecated. Because modules are cached, all
3783 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

3797 to _sre.compile() will now be rejected. This should not affect anybody
3798 since the re.compile() function never generates invalid re-bytecode.
3799
Skip Montanaroa032bf42008-08-08 22:52:51 +00003800- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

3802 it wasn't initialized during instantiation.
3803
Brett Cannon3aa2a492008-08-06 22:28:09 +00003804- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3805 the reload() built-in has been removed.
3806
Brett Cannon7e30b672008-08-04 21:52:25 +00003807- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00003819 asking for a specific length. This problem only affected files opened
3820 using the new "io" module, not the built-in open() function.

3846 file name rather than a ZipInfo instance, so files are extracted with
3847 mode 0600 rather than 000 under Unix.
3848
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003849- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3850 argument in python 2.5, this broke code that subclassed Popen to include its

3862 interaction with the tp_hash slot (added in 2.6b2) are now documented
3863
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003864- Issue #643841: The language reference now provides more detailed
3865 coverage of the lookup process for special methods. The disclaimers
3866 regarding lack of coverage of new-style classes have also been
3867 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003875Core and Builtins
3876-----------------
3877
Georg Brandl3e483f62008-07-16 22:57:41 +00003878- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3879 its methods now allow for items objects that can be converted to
3880 an integer using operator.index().
3881
Mark Dickinson64b7e502008-07-16 09:40:03 +00003882- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3883 produced a ValueError instead of giving the correct float.
3884
Eric Smitha5fa5a22008-07-16 00:11:49 +00003885- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3886 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3887
Mark Dickinson7103aa42008-07-15 19:08:33 +00003888- Issue #3008: the float type has a new instance method 'float.hex'
3889 and a new class method 'float.fromhex' to convert floating-point
3890 numbers to and from hexadecimal strings, respectively.
3891
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003892- Issue #2235: __hash__ is once again inherited by default. To allow
3893 collections.Hashable to remain meaningful in the presence of the
3894 default hash implementation (object.__hash__), it is now possible
3895 to explicit block inheritance of hash by setting __hash__=None at
3896 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3897 level.
3898
Nick Coghlanb028f502008-07-13 14:52:36 +00003899- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3900 the parent module cannot be found while performing an absolute import.
3901 This means that an incorrectly defined __package__ attribute will
3902 now only prevent relative imports in that module rather than causing
3903 all imports from that module to fail.
3904
Nick Coghlan14ff9942008-07-08 14:21:42 +00003905- Issue #2517: Allow unicode messages in Exceptions again by correctly
3906 bypassing the instance dictionary when looking up __unicode__ on
3907 new-style classes.
3908
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003909- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3910 set to a custom object whose write() method happens to install
3911 another file in sys.stdout.
3912
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003913- Issue #3088: Corrected a race condition in classes derived from
3914 threading.local: the first member set by a thread could be saved in
3915 another thread's dictionary.
3916
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003917- Issue #3004: Minor change to slice.indices(): the start and stop
3918 arguments are now treated identically, making the behaviour easier
3919 to describe and understand. For example, slice(None, -10,
3920 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3921 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3922 10, -1).
3923
Georg Brandl278fc502008-07-19 12:46:12 +00003924- Issue #3219: Calling a function with repeated keyword arguments,
3925 f(a=2, a=23), would not cause a syntax error. This was a regression
3926 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003927
Georg Brandl278fc502008-07-19 12:46:12 +00003928- Issue #2862: Make int and float freelist management consistent with
3929 other freelists. Changes their CompactFreeList apis into
3930 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003931

3934
Thomas Heller57adf222008-08-14 19:10:48 +00003935- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3936 api functions without holding the GIL, which could lead to a fatal
3937 error when they failed.
3938
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003939- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3948 ForkingPickler.register() to resolve conflict with ctypes.
3949
Vinay Sajip51e65192008-07-18 09:01:10 +00003950- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

3953 a valid dlerror() message.
3954
Thomas Heller2bad6572008-07-15 17:19:50 +00003955- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3956 incomplete structure was created.
3957

3961
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003962- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003963
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003964- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3965 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003966 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003967 content-length. The problem had been corrected in the 2.4 branch, but never
3968 merged into trunk.
3969
Georg Brandle78fbcc2008-07-05 10:13:36 +00003970- Issue #2663: add filtering capability to shutil.copytree().

4375 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004376 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004377
4378 This is controlled by the configure argument ``--with-universal-archs``:
4379
4380 - ``--with-universal-archs=all``: install 4-way universal
4381
4382 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4383
4384 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4385
4386 This option should be used in combination with ``--enable-universalsdk=``.
4387
4388 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 +00004438- Issue #1631171: Re-implement the 'warnings' module in C (the
4439 original Python code has been kept as backup). This will allow for
4440 using the 'warning's machinery in such places as the parser where
4441 use of pure Python code is not possible. Both the ``showarning()``
4442 and ``formatwarning()`` gain an optional 'line' argument which is
4443 not called by default for backwards-compatibility reasons. Setting
4444 ``warnings.showwarning()`` to an implementation that lacks support
4445 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004508- Issue #2550: The approach used by client/server code for obtaining
4509 ports to listen on in network-oriented tests has been refined in an
4510 effort to facilitate running multiple instances of the entire
4511 regression test suite in parallel without issue.
4512 test_support.bind_port() has been fixed such that it will always
4513 return a unique port -- which wasn't always the case with the
4514 previous implementation, especially if socket options had been set
4515 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4516 new implementation of bind_port() will actually raise an exception
4517 if it is passed an AF_INET/SOCK_STREAM socket with either the
4518 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4519 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4520 the socket it's been passed. This currently only applies to
4521 Windows. This option prevents any other sockets from binding to the
4522 host/port we've bound to, thus removing the possibility of the
4523 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4524 when a second SOCK_STREAM socket binds and accepts to a host/port
4525 that's already been bound by another socket. The optional preferred
4526 port parameter to bind_port() has been removed. Under no
4527 circumstances should tests be hard coding ports!
4528
4529 test_support.find_unused_port() has also been introduced, which will
4530 pass a temporary socket object to bind_port() in order to obtain an
4531 unused port. The temporary socket object is then closed and
4532 deleted, and the port is returned. This method should only be used
4533 for obtaining an unused port in order to pass to an external program
4534 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4535 a parameter to a server-oriented class that doesn't give you direct
4536 access to the underlying socket used.
4537
4538 Finally, test_support.HOST has been introduced, which should be used
4539 for the host argument of any relevant socket calls (i.e. bind and
4540 connect).

4815-----------------
4816
Fred Drakea8ee94b2008-03-01 02:45:07 +00004817- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004818 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004819
Georg Brandlad61bc82008-02-23 15:11:18 +00004820- Issue #2067: file.__exit__() now calls subclasses' close() method.
4821
4822- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004823
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004824- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00004825 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00004826
Eric Smitha73fbe72008-02-23 03:09:44 +00004827- Added the future_builtins module, which contains hex() and oct().
4828 These are the PEP 3127 version of these functions, designed to be
4829 compatible with the hex() and oct() builtins from Python 3.0. They
4830 differ slightly in their output formats from the existing, unchanged
4831 Python 2.6 builtins. The expected usage of the future_builtins
4832 module is:
4833 from future_builtins import hex, oct
4834
Eric Smith7ef40bf2008-02-20 23:34:22 +00004835- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4836 exponents for exponents with absolute value < 100. Follows C99
4837 standard. This is a change on Windows, which would use 3 digits.
4838 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4839 so that any alterations it does to the resulting string will be
4840 available in stringlib/formatter.h (for float.__format__).
4841
Eric Smith5a3c1352008-02-19 13:21:56 +00004842- Implemented PEP 3101, Advanced String Formatting. This adds a new
4843 builtin format(); a format() method for str and unicode; a
4844 __format__() method to object, str, unicode, int, long, float, and
4845 datetime; the class string.Formatter; and the C API
4846 PyObject_Format().
4847
Georg Brandl3ee81df2008-05-17 18:14:43 +00004848- Fixed several potential crashes, all caused by specially crafted
4849 __del__ methods exploiting objects in temporarily inconsistent
4850 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004851
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004852- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004853 prevent a possible crash: an Abstract Base Class would try to access
4854 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004855
Georg Brandl3ee81df2008-05-17 18:14:43 +00004856- Fixed repr() and str() of complex numbers with infinity or nan as
4857 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004858
Georg Brandl3ee81df2008-05-17 18:14:43 +00004859- Clear all free lists during a gc.collect() of the highest generation
4860 in order to allow pymalloc to free more arenas. Python may give back
4861 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004862
Georg Brandl3ee81df2008-05-17 18:14:43 +00004863- Issue #2045: Fix an infinite recursion triggered when printing a
4864 subclass of collections.defaultdict, if its default_factory is set
4865 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004866
Christian Heimesf75dbef2008-02-08 00:11:31 +00004867- Fixed a minor memory leak in dictobject.c. The content of the free
4868 list was not freed on interpreter shutdown.
4869
Georg Brandl21e99f42010-03-07 15:23:59 +00004870- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004871 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004872
Georg Brandl3ee81df2008-05-17 18:14:43 +00004873- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4874 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004875 to compact the internal free lists of pre-allocted ints and floats.
4876
Georg Brandl3ee81df2008-05-17 18:14:43 +00004877- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4878 calls. Python expected the return type int but the fork familie
4879 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004880
Georg Brandl3ee81df2008-05-17 18:14:43 +00004881- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4882 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004883
Georg Brandl3ee81df2008-05-17 18:14:43 +00004884- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4885 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004886
Georg Brandl3ee81df2008-05-17 18:14:43 +00004887- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4888 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004889
Georg Brandl3ee81df2008-05-17 18:14:43 +00004890- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4891 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004892
Georg Brandl3ee81df2008-05-17 18:14:43 +00004893- Patch #1473257: generator objects gain a gi_code attribute. This is
4894 the same object as the func_code attribute of the function that
4895 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004896
Georg Brandl3ee81df2008-05-17 18:14:43 +00004897- Issue #1920: "while 0" statements were completely removed by the
4898 compiler, even in the presence of an "else" clause, which is
4899 supposed to be run when the condition is false. Now the compiler
4900 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004901
Guido van Rossumeead05f2008-01-24 18:21:02 +00004902- A few crashers fixed: weakref_in_del.py (issue #1377858);
4903 loosing_dict_ref.py (issue #1303614, test67.py);
4904 borrowed_ref_[34].py (not in tracker).
4905
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004906- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004907 suppressed while an extension is loaded by calling SetErrorMode in
4908 dynload_win.c. The error is still reported properly.
4909
Georg Brandl3ee81df2008-05-17 18:14:43 +00004910- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004911 several extension methods and modules do not work without unicode
4912 support.
4913
Georg Brandl26543b12008-01-21 18:36:51 +00004914- Issue #1882: when compiling code from a string, encoding cookies in the
4915 second line of code were not always recognized correctly.
4916
Georg Brandl14404b62008-01-19 19:27:05 +00004917- Issue #1679: "0x" was taken as a valid integer literal.
4918
Georg Brandl6caad7d2008-01-26 14:19:22 +00004919- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004920 added.
4921
Christian Heimesc94e2b52008-01-14 04:13:37 +00004922- sys.float_info / PyFloat_GetInfo: The floating point information
4923 object was converted from a dict to a specialized structseq object.
4924
Georg Brandl3ee81df2008-05-17 18:14:43 +00004925- Patch #1816: Added sys.flags structseq. It exposes the status of
4926 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004927
Georg Brandl3ee81df2008-05-17 18:14:43 +00004928- Objects/structseq.c: Implemented new structseq representation. The
4929 patch makes structseqs (e.g. the return value of os.stat) more
4930 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004931
Georg Brandl3ee81df2008-05-17 18:14:43 +00004932- Patch #1700288: added a type attribute cache that caches method
4933 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004934
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004935- Bug #1776: __import__() no longer accepts filenames on any platform.
4936 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004937
Georg Brandlaed6c662008-01-07 17:25:53 +00004938- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4939
Georg Brandl3ee81df2008-05-17 18:14:43 +00004940- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4941 envvar and sys.dont_write_bytecode attribute. All these can be set
4942 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004943
Georg Brandl3ee81df2008-05-17 18:14:43 +00004944- Improve some exception messages when Windows fails to load an
4945 extension module. Now we get for example '%1 is not a valid Win32
4946 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004947
Georg Brandl3ee81df2008-05-17 18:14:43 +00004948- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004950- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4951 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004952
Christian Heimes0a8143f2007-12-18 23:22:54 +00004953- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004954 and INF. float("nan"), float("inf") and float("-inf") now work on
4955 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004956
Georg Brandl3ee81df2008-05-17 18:14:43 +00004957- Compiler now generates simpler and faster code for dictionary
4958 literals. The oparg for BUILD_MAP now indicates an estimated
4959 dictionary size. There is a new opcode, STORE_MAP, for adding
4960 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004961
Georg Brandl3ee81df2008-05-17 18:14:43 +00004962- Issue #1638: %zd configure test fails on Linux.

4972
Nick Coghlanef01d822007-12-03 12:55:17 +00004973- PEP 366: Allow explicit relative imports when executing modules
4974 inside packages with the -m switch via a new module level
4975 __package__ attribute.
4976
Georg Brandl3ee81df2008-05-17 18:14:43 +00004977- Issue #1402: Fix a crash on exit, when another thread is still
4978 running, and if the deallocation of its frames somehow calls the
4979 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004980

Georg Brandl3ee81df2008-05-17 18:14:43 +00004994- Issue #1265: Fix a problem with sys.settrace, if the tracing
4995 function uses a generator expression when at the same time the
4996 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004997
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004998- sets and frozensets now have an isdisjoint() method.
4999
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005000- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00005002- Fix warnings found by the new version of the Coverity checker.
5003
Georg Brandl21e99f42010-03-07 15:23:59 +00005004- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005005 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5006 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005007
Georg Brandl3ee81df2008-05-17 18:14:43 +00005008- Issue #1686386: Tuple's tp_repr did not take into account the
5009 possibility of having a self-referential tuple, which is possible
5010 from C code. Nor did object's tp_str consider that a type's tp_str
5011 could do something that could lead to an inifinite recursion.
5012 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5013 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005014
Georg Brandl3ee81df2008-05-17 18:14:43 +00005015- Issue #1164: It was possible to trigger deadlock when using the
5016 'print' statement to write to a file since the GIL was not released
5017 as needed. Now PyObject_Print() does the right thing along with
5018 various tp_print implementations of the built-in types and those in
5019 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005020
Georg Brandl3ee81df2008-05-17 18:14:43 +00005021- Issue #1147: Exceptions were directly allowing string exceptions in
5022 their throw() method even though string exceptions no longer
5023 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005024

Brett Cannon1e534b52007-09-07 04:18:30 +00005028- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005029 PyObject_Call() never calling back out to Python code to trigger
5030 recursion depth updates/checks. Required the creation of a static
5031 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005049 __*__ attributes. (Some already existed, e.g., __doc__ and
5050 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005051

5060 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005068 setting a plain string, ie don't expand to single letter identifiers.
5069
Raymond Hettinger13936692007-04-11 18:40:58 +00005070- Request #1191699: Slices can now be pickled.

5080
Guido van Rossum143b5642007-03-23 04:58:42 +00005081- Bug #1683368: The object.__init__() and object.__new__() methods are
5082 now stricter in rejecting excess arguments. The only time when
5083 either allows excess arguments is when it is not overridden and the
5084 other one is. For backwards compatibility, when both are
5085 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005086 warning later). Also, type.__init__() insists on the same signature
5087 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005089- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5090 object to complex using its __complex__() method before falling back
5091 to the __float__() method. Therefore, the functions in the cmath
5092 module now can operate on objects that define a __complex__()
5093 method.

5110
Georg Brandl7b9c5552007-03-12 14:30:05 +00005111- Bug #1678647: write a newline after printing an exception in any
5112 case, even when converting the value to a string failed.
5113
Georg Brandl871f1bc2007-03-12 13:17:36 +00005114- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005115 its argument, if it exists. If not, it will work like before. This
5116 allows customizing the output of dir() in the presence of a
5117 __getattr__().

5127 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005128
Georg Brandlaa2321b2007-03-07 00:40:28 +00005129- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005130 makes the filenames the warning module prints much more sensible
5131 when a PYTHONSTARTUP file is used.

5145 sq_ass_slice instead of the sq_slice slot.
5146
Georg Brandl3ee81df2008-05-17 18:14:43 +00005147- When printing an unraisable error, don't print exceptions. before

5776 incompatibility since it never made sense with ordinary subclasses
5777 -- the failure just occurred later, with a more cumbersome
5778 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006059- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6060 with RFC 3207 and forgets any knowledge obtained from the server not
6061 obtained from the TLS negotiation itself. Patch contributed by Bill
6062 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006063
Georg Brandl3ee81df2008-05-17 18:14:43 +00006064- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006065 that the SMTP.starttls() caller no longer needs to call ehlo()
6066 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006067 does not claim to support starttls. Adds the
6068 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6149 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6150 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00006167 time so that opening a database previously created with the DB_DUP
6168 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6169 opens. Specifically: dictionary assignment to a DB object will
6170 replace all values for a given key when the database allows
6171 duplicate values. DB users should use DB.put(k, v) when they want
6172 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006173

6179 characters with ASCII value less than 32. Also, it correctly quotes
6180 dots only if they occur on a single line, as opposed to the previous
6181 behavior of quoting dots if they are the second character of any
6182 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006499- Makefile.pre.in(buildbottest): Run an optional script
6500 pybuildbot.identify to include some information about the build
6501 environment.

6505-----
6506
Georg Brandl3ee81df2008-05-17 18:14:43 +00006507- Unified naming convention for free lists and their limits. All free
6508 lists in Object/ are named ``free_list``, the counter ``numfree``
6509 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6510 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006511
Georg Brandl3ee81df2008-05-17 18:14:43 +00006512- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6513 to ``PyTuple_SetItem``, it can be used to populate a brand new
6514 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006515
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006516- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006517
Georg Brandl3ee81df2008-05-17 18:14:43 +00006518- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6519 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6520 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006521
6522- Patch #1720595: add T_BOOL to the range of structmember types.
6523
6524- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6525 ``PyFloat_GetInfo()`` to the float API.
6526
Georg Brandl3ee81df2008-05-17 18:14:43 +00006527- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6528 of w# format code incorrectly truncated the length to an int, even
6529 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6530 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006531
Georg Brandl3ee81df2008-05-17 18:14:43 +00006532- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6533 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006534
Georg Brandl3ee81df2008-05-17 18:14:43 +00006535- PEP 3123: Provide forward compatibility with Python 3.0, while
6536 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6537 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006538
Georg Brandl3ee81df2008-05-17 18:14:43 +00006539- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6540 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006541
6542- Patch #1733960: Allow T_LONGLONG to accept ints.
6543
6544- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6545
Christian Heimes000a0742008-01-03 22:16:32 +00006546- Added a new API function ``PyImport_ImportModuleNoBlock``.
6547
Georg Brandl6caad7d2008-01-26 14:19:22 +00006548- Bug #1637022: Prefix AST symbols with _Py_.
6549
6550- Fix some leftovers from the conversion from int to Py_ssize_t
6551 (relevant to strings and sequences of more than 2**31 items).
6552
6553- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6554 outside of pystate.c and should not be necessary.
6555
Georg Brandl3ee81df2008-05-17 18:14:43 +00006556- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6557 absolute imports. In earlier versions they might have used relative
6558 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006559
Georg Brandl3ee81df2008-05-17 18:14:43 +00006560- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6561 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006562
Georg Brandl3ee81df2008-05-17 18:14:43 +00006563- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6564 macro so it can be used as an expression.

6569
Georg Brandl3ee81df2008-05-17 18:14:43 +00006570- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6571 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6572 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6573 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006574
Georg Brandl3ee81df2008-05-17 18:14:43 +00006575- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
6576 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006588- Removed the macfs module. It had been deprecated since Python 2.5.
6589 This lead to the deprecation of macostools.touched() as it relied
6590 solely on macfs and was a no-op under OS X.
