Mark Dickinsoncb61e5d2010-09-26 10:37:12 +000015- Issue #9869: Make long() and PyNumber_Long return something of type
16 long for a class whose __long__ method returns a plain int. This
17 fixes an interpreter crash when initializing an instance of a long
18 subclass from an object whose __long__ method returns a plain int.
19
Antoine Pitrou0a7b65b2010-09-08 12:40:49 +000020- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
21 thread-local storage key.
22
Victor Stinnercaafd772010-09-08 10:51:01 +000023- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
24 encoding and errors attributes instead of using utf-8 in strict mode, to get
25 the same behaviour than the print statement.
26
Antoine Pitrou9cf85f12010-09-01 21:17:34 +000027- Issue #9737: Fix a crash when trying to delete a slice or an item from
28 a memoryview object.
29

35 of an array.
36
Raymond Hettinger3ad323e2010-08-06 10:18:56 +000037- Issue #83755: Implicit set-to-frozenset conversion was not thread-safe.
38
Mark Dickinsonaad57bd2010-08-01 10:45:15 +000039- Issue #9416: Fix some issues with complex formatting where the
40 output with no type specifier failed to match the str output:
41
42 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
43 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
44
Antoine Pitrou32669782010-07-11 12:14:05 +000045- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
46 compiler.

Vinay Sajip3eac5912010-09-25 17:48:25 +000051- Issue #9947: logging: Fixed locking bug in stopListening.
52
Vinay Sajip546885e2010-09-25 17:42:36 +000053- Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler.
54
Alexander Belopolsky517185e2010-09-24 18:14:18 +000055- Issue #9936: Fixed executable lines' search in the trace module.
56
Antoine Pitrou2c7d6852010-09-23 19:55:24 +000057- Issue #9928: Properly initialize the types exported by the bz2 module.
58
Antoine Pitrou6391b342010-09-14 18:48:19 +000059- Issue #9854: The default read() implementation in io.RawIOBase now
60 handles non-blocking readinto() returning None correctly.
61
Antoine Pitrouf7f390a2010-09-14 14:37:18 +000062- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
63 SSLSocket.sendto() to match the corresponding socket methods. Also,
64 fix various SSLSocket methods to raise socket.error rather than an
65 unhelpful TypeError when called on an unconnected socket. Original patch
66 by Andrew Bennetts.
67
Raymond Hettinger74f869e2010-09-13 22:14:36 +000068- Issue #9826: OrderedDict.__repr__ can now handle self-referential
69 values: d['x'] = d.
70
Victor Stinner8fc843b2010-09-17 23:35:50 +000071- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
Victor Stinner46287f52010-09-13 20:31:34 +000072
Antoine Pitroue4195e82010-09-12 14:56:27 +000073- Issue #9837: The read() method of ZipExtFile objects (as returned by
74 ZipFile.open()) could return more bytes than requested.
75
Raymond Hettinger20397532010-09-12 02:11:45 +000076- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
77 This prevents user-created self-referencing ordered dictionaries from
78 becoming permanently uncollectable GC garbage. The downside is that
79 removing __del__ means that the internal doubly-linked list has to wait for
80 GC collection rather than freeing memory immediately when the refcnt drops
81 to zero.
82
Raymond Hettingerffd2a422010-09-10 10:47:22 +000083- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
84 different internal state for small values of n. Fixed by salting the
85 value.
86
Antoine Pitrouc818ed42010-09-07 21:40:25 +000087- Issue #9792: In case of connection failure, socket.create_connection()
88 would swallow the exception and raise a new one, making it impossible
89 to fetch the original errno, or to filter timeout errors. Now the
90 original error is re-raised.
91
Antoine Pitrouf4f61712010-09-07 16:34:47 +000092- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
93 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
94 be updated back after the system call. Original patch by Brian Brazil.
95
Antoine Pitroudca9de92010-09-04 17:52:26 +000096- Issue #1100562: Fix deep-copying of objects derived from the list and
97 dict types. Patch by Michele Orrù and Björn Lindqvist.
98
Fred Drakea1e627d2010-09-03 03:55:50 +000099- Issue #7005: Fixed output of None values for RawConfigParser.write and
100 ConfigParser.write.
101
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000102- Issue #808164: Fixed socket.close to avoid references to globals, to
103 avoid issues when socket.close is called from a __del__ method.
104
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000105- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
106 falling into recursion.
107
R. David Murray7c4bf552010-08-25 01:45:57 +0000108- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
109 character years even if the message contains RFC822 two character years.
110
Daniel Stutzbach91287322010-08-24 21:09:30 +0000111- Issue #8750: Fixed MutableSet's methods to correctly handle
112 reflexive operations, namely x -= x and x ^= x.
113
Victor Stinnercaafd772010-09-08 10:51:01 +0000114- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000115 error handling when accepting a new connection.
116
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000117- Issue #658749: asyncore's connect() method now correctly interprets winsock
118 errors.
119
Vinay Sajip1ddd51f2010-08-23 17:50:30 +0000120- Issue #9501: Fixed logging regressions in cleanup code.
121

123 module now correctly return a set. (Patch by Eli Bendersky.)
124
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000125- Issue #9617: Signals received during a low-level write operation aren't
126 ignored by the buffered IO layer anymore.
127
Benjamin Peterson52c36052010-08-21 03:03:22 +0000128- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
129 are not held onto after they are deleted elsewhere.
130
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000131- Issue #9626: the view methods for collections.OrderedDict() were returning
132 the unordered versions inherited from dict. Those methods are now
133 overridden to provide ordered views.
134
Éric Araujo0389ae62010-08-14 03:07:46 +0000135- Issue #8688: MANIFEST files created by distutils now include a magic
136 comment indicating they are generated. Manually maintained MANIFESTs
137 without this marker will not be overwritten or removed.
138
Antoine Pitroue1436d12010-08-12 15:25:51 +0000139- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
140 and a BadZipfile error is raised if it doesn't match (as used to be the
141 case in Python 2.5 and earlier).
142
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000143- Issue #9550: a BufferedReader could issue an additional read when the
144 original read request had been satisfied, which could block indefinitely

146 patch by Jason V. Miller.
147
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000148- Issue #9551: Don't raise TypeError when setting the value to None for

152 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
153
Antoine Pitrou99009162010-08-09 22:51:24 +0000154- Issue #3757: thread-local objects now support cyclic garbage collection.
155 Thread-local objects involved in reference cycles will be deallocated
156 timely by the cyclic GC, even if the underlying thread is still running.
157
Florent Xicluna2f1b1ff2010-08-09 20:46:49 +0000158- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the

Senthil Kumarane677ecf2010-08-08 11:56:31 +0000166- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
167 This is how it is supposed to work, wget and curl do the same. Previous
168 behavior was wrong.
169
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +0000170- Issue #2944: asyncore doesn't handle connection refused correctly.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000508- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
509 start byte and the continuation byte(s) are now considered invalid, instead
510 of the number of bytes specified by the start byte.
511 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
512 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
513 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

523 objects. (1) The comparison could incorrectly return True in some cases
524 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000666- Issue #1533: Fix inconsistency in range function argument processing: any
667 non-float non-integer argument is now converted to an integer (if possible)
668 using its __int__ method. Previously, only small arguments were treated this
669 way; larger arguments (those whose __int__ was outside the range of a C long)
670 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +0000678 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable

722 trapped, the specification determines the order in which the signals should be
723 handled. In many cases this order wasn't being followed, leading to the wrong
724 Python exception being raised.

Georg Brandlfee0f442010-05-22 21:26:21 +0000868- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000869 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
870 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
871 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

891Core and Builtins
892-----------------
893
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000894- Issue #7301: Add environment variable $PYTHONWARNINGS.
895
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000896- Issue #8329: Don't return the same lists from select.select when no fds are
897 changed.
898
Georg Brandlfee0f442010-05-22 21:26:21 +0000899- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000900 on 64-bit machines. The shift count for either left or right shift is
901 permitted to be up to sys.maxsize.
902
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000903- Ensure that tokenization of identifiers is not affected by locale.
904
Georg Brandlfee0f442010-05-22 21:26:21 +0000905- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000906
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000907- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
908
Georg Brandlfee0f442010-05-22 21:26:21 +0000909- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
910 with a non-empty format string. This is an effort to future-proof user
911 code. If a derived class does not currently implement __format__ but later
912 adds its own __format__, it would most likely break user code that had
913 supplied a format string. This will be changed to a DeprecationWaring in
914 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000941- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000942 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

946
Georg Brandlfee0f442010-05-22 21:26:21 +0000947- Issue #8257: The Decimal construct now accepts a float instance directly,
948 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000949
950 >>> Decimal(1.1)
951 Decimal('1.100000000000000088817841970012523233890533447265625')
952
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000953- collections.Counter() now supports a subtract() method.
954
Georg Brandlfee0f442010-05-22 21:26:21 +0000955- The functools module now has a total_ordering() class decorator to simplify
956 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000957
Georg Brandlfee0f442010-05-22 21:26:21 +0000958- The functools module also adds cmp_to_key() as a tool to transition old-style
959 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000960
Georg Brandlfee0f442010-05-22 21:26:21 +0000961- Issue #8294: The Fraction constructor now accepts Decimal and float instances
962 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000963
Georg Brandlfee0f442010-05-22 21:26:21 +0000964- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
965 InvalidOperation instead of returning False. (Comparisons involving a quiet
966 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
967 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000968
Georg Brandlfee0f442010-05-22 21:26:21 +0000969- Issue #2531: Comparison operations between floats and Decimal instances now
970 return a result based on the numeric values of the operands; previously they
971 returned an arbitrary result based on the relative ordering of id(float) and
972 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000973
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000974- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000975 argument `-` which tells it to read files to compile from stdin. Each line is
976 read on demand and the named file is compiled immediately. (Original patch by
977 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000978
Georg Brandlfee0f442010-05-22 21:26:21 +0000979- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000982- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
983 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000984 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +0000986- Comparisons using one of <, <=, >, >= between a complex instance and a
987 Fractions instance now raise TypeError instead of returning True/False. This
988 makes Fraction <=> complex comparisons consistent with int <=> complex, float
989 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000990

999
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001000- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001001 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1002 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001003
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001004- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1005 deprecated.
1006
Georg Brandlfee0f442010-05-22 21:26:21 +00001007- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001044- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001045 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1046 log file to compute the next rollover time. If the log file does not exist,
1047 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001048
Georg Brandlba83f822010-03-14 09:50:54 +00001049- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

1058 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1059 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001088- Issue #8300: When passing a non-integer argument to struct.pack with any
1089 integer format code, struct.pack first attempts to convert the non-integer
1090 using its __index__ method. If that method is non-existent or raises

Georg Brandlba83f822010-03-14 09:50:54 +00001093- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1094 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1095 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001096 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1097 inconsistent: __int__ was used for some integer codes but not for others, and
1098 the set of integer codes for which it was used differed between native packing
1099 and standard packing.)

1500-----------------
1501
Georg Brandlba83f822010-03-14 09:50:54 +00001502- The ``__complex__()`` method is now looked up on the class of instances to
1503 make it consistent with other special methods.

1507
Mark Dickinson1b34d252010-01-01 17:27:30 +00001508- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001509 DeprecationWarning when passed a float argument where an integer was expected.
1510 These functions and methods now raise TypeError instead. The majority of the
1511 effects of this change are in the extension modules, but some core functions
1512 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1513 and many unicode/str methods.

1525
Georg Brandlba83f822010-03-14 09:50:54 +00001526- Issue #1811: Improve accuracy and cross-platform consistency for true division
1527 of integers: the result of a/b is now correctly rounded for ints a and b (at
1528 least on IEEE 754 platforms), and in particular does not depend on the
1529 internal representation of a long.

1537
Georg Brandlba83f822010-03-14 09:50:54 +00001538 These executables now work properly with the arch(1) command: ``arch -ppc
1539 python`` will start a universal binary version of python in PPC mode (unlike

1680 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001681
Georg Brandlba83f822010-03-14 09:50:54 +00001682- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1683 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001684
Georg Brandlba83f822010-03-14 09:50:54 +00001685- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001695
Georg Brandlba83f822010-03-14 09:50:54 +00001696- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1697 decimal string that's guaranteed to round back to x under correct rounding
1698 (with round-half-to-even rounding mode). Previously it gave a string based on
1699 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1700 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1701 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001702
Georg Brandlba83f822010-03-14 09:50:54 +00001703- Issue #7117: On almost all platforms: float-to-string and string-to-float
1704 conversions within Python are now correctly rounded. Places these conversions
1705 occur include: str for floats and complex numbers; the float and complex
1706 constructors; old-style and new-style numeric formatting; serialization and
1707 deserialization of floats and complex numbers using marshal, pickle and json;
1708 parsing of float and imaginary literals in Python code; Decimal-to-float
1709 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001710
Georg Brandlba83f822010-03-14 09:50:54 +00001711 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1712 providing correctly-rounded strtod and dtoa C functions. This code is
1713 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1714 the C compiler. There may be a small number of platforms on which correct
1715 operation of this code cannot be guaranteed, so the code is not used: notably,
1716 this applies to platforms where the C double format is not IEEE 754 binary64,
1717 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1718 and Python's configure script is unable to determine how to change the FPU
1719 precision. On these platforms conversions use the platform strtod and dtoa,
1720 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001721
Georg Brandlba83f822010-03-14 09:50:54 +00001722- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1723 uses the correctly-rounded string <-> float conversions described above (when
1724 available), and so produces correctly rounded results that will display nicely
1725 under the float repr. There are two related small changes: (1) round now
1726 accepts any class with an ``__index__()`` method for its second argument (but
1727 no longer accepts floats for the second argument), and (2) an excessively
1728 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1729 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001871
Georg Brandlba83f822010-03-14 09:50:54 +00001872 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1873 (2) parsing of strings representing infinities and nans was locale aware; and
1874 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00001875
Georg Brandlba83f822010-03-14 09:50:54 +00001876- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1877 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1878 but with at least one decimal point and with a default precision
1879 of 12. Previously, the behavior the same but with a default precision of 6.
1880 This more closely matches ``str()``, and reduces surprises when adding
1881 alignment flags to the empty presentation type. This also affects the new
1882 complex.__format__ in the same way.
1883
1884- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1885 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00001947 untrackable objects are not tracked by the garbage collector. This can reduce
1948 the size of collections and therefore the garbage collection overhead on
1949 long-running programs, depending on their particular use of datatypes.

1956 internal representation of integers, for performance reasons. Base 2**30 is
1957 enabled by default on 64-bit machines. Add --enable-big-digits option to
1958 configure, which overrides the default. Add sys.long_info structseq to
1959 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00002080- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2081 file objects with closefd=False. The file descriptor is still kept open but
2082 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00002106- On windows, ``os.chdir()`` given unicode was not working if

2108 this code path is really executed because I cannot move to such directory on
2109 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002111- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2112 element is temporarily replaced with an equivalent frozenset. But the
2113 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00002134- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2135 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2136 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2137 of using the replace error handler in PyUnicode_DecodeUTF8().
2138
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002139- Issue #3739: The unicode-internal encoder now reports the number of characters

2141
Georg Brandlba83f822010-03-14 09:50:54 +00002142- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2144 gives improved memory leak detection when running under Valgrind, while taking
2145 advantage of pymalloc at other times.

3511
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003512- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3513 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3514 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3515 ``printf`` function, whereas PyString_FromFormat has an independent
3516 implementation and uses "%zd" on all platforms for size_t values.
3517 This makes a difference on win64, where ``printf`` needs "%Id" to display
3518 64bit values.

3524 object; previously an int would be returned for small values. the __long__
3525 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003535 was correctly parsed but parsing of subsequent arguments failed.
3536
Vinay Sajip35e3b032008-09-01 14:33:59 +00003537- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003538 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3539 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3540 when given a tuple of classes as second argument, were looking up
3541 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3542 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00003689- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3690 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3691 extensions do not automatically benefit from the class attribute
3692 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3693 to their tp_flags field if they care. This is a backwards
3694 compatibility feature; in 3.0, all types will use the cache by
3695 default.

Benjamin Petersonf647dc12008-08-20 01:27:30 +00003697- Keyword arguments can now follow starred arguments. (``f(a, *args,
3698 keyword=23)`` is now valid syntax.)
3699
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003700- ctypes function pointers that are COM methods have a boolean True
3701 value again.
3702
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003703- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3704 by denying s# to parse objects that have a releasebuffer procedure,
3705 and introducing s*.
3706
Georg Brandl1e13ea92008-08-11 09:07:59 +00003707- Issue #3537: Fix an assertion failure when an empty but presized dict
3708 object was stored in the freelist.
3709
Mark Dickinsonb6467572008-08-04 21:30:09 +00003710- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3711 ValueError consistently across platforms.
3712
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003713- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3714 (64bit Unix, for example), unichr() would truncate its argument and return
3715 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3716
Neal Norwitze7d8be82008-07-31 17:17:14 +00003717- Apply security patches from Apple.
3718
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003719- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3720 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3721
Antoine Pitrou92f82162008-07-25 22:22:08 +00003722- Issue #1819: function calls with several named parameters are now on
3723 average 35% faster (as measured by pybench).
3724
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003725- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3726 the python debugger steps into a class statement: the free variables (local
3727 variables defined in an outer scope) would be deleted from the outer scope.
3728
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003729- Issue #2620: Overflow checking when allocating or reallocating memory
3730 was not always being done properly in some python types and extension
3731 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3732 all been updated to perform better checks and places in the code that
3733 would previously leak memory on the error path when such an allocation
3734 failed have been fixed.

3740
Benjamin Petersone977ad42008-08-20 01:42:01 +00003741- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3742 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3743
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003744- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3745 version reported by these tools does not necessarily follow the python
3746 version numbering scheme, so the module is less strict when parsing it.
3747
Nick Coghlanf70385a2008-08-18 12:42:46 +00003748- Issue #2235: Added Py3k warnings for types which will become unhashable
3749 under the stricter __hash__ inheritance rules in 3.0. Several types
3750 which did not meet the rules for hash invariants and were already
3751 unhashable in 3.0 have now been explicitly flagged as unhashable in
3752 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3753 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3754
Brett Cannon88f801d2008-08-18 00:46:22 +00003755- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3756 imported into the module but exposed as part of the module's API.
3757

3763
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003764- Issue #3575: Incremental decoder's decode function now takes bytearray
3765 by using 's*' instead of 't#'.
3766
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003767- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003768 fails unicode conversion on 2nd parameter. (windows only)

Facundo Batistaeb90b782008-08-16 14:44:07 +00003776- Issue #2776: fixed small issue when handling an URL with double slash
3777 after a 302 response in the case of not going through a proxy.
3778
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003779- Issue #2676: in the email package, content-type parsing was hanging on
3780 pathological input because of quadratic or exponential behaviour of a
3781 regular expression.
3782
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003783- Issue #3476: binary buffered reading through the new "io" library is now
3784 thread-safe.
3785
Brett Cannonbf3157b2008-08-14 05:00:03 +00003786- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3787 since mimetools itself is deprecated. Because modules are cached, all
3788 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3789
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003790- Issue #3134: shutil referenced undefined WindowsError symbol.

3793 menu entries were not deleted.
3794
Brett Cannon83e81842008-08-09 23:30:55 +00003795- Copied the implementation of reduce() to _functools.reduce() to have a

3797
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003798- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3799 a MemoryError rather than silently stop the iteration.
3800
Guido van Rossum59ce9012008-08-09 14:55:34 +00003801- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3802 to _sre.compile() will now be rejected. This should not affect anybody
3803 since the re.compile() function never generates invalid re-bytecode.
3804
Skip Montanaroa032bf42008-08-08 22:52:51 +00003805- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3806 upon first access it can be automatically initialized from the csv file if
3807 it wasn't initialized during instantiation.
3808
Brett Cannon3aa2a492008-08-06 22:28:09 +00003809- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3810 the reload() built-in has been removed.
3811
Brett Cannon7e30b672008-08-04 21:52:25 +00003812- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003813 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3821 raised an AttributeError.
3822
Benjamin Peterson01a24322008-07-28 23:35:27 +00003823- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003824 asking for a specific length. This problem only affected files opened
3825 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003826

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003850- Issue #3394: zipfile.writestr sets external attributes when passed a
3851 file name rather than a ZipInfo instance, so files are extracted with
3852 mode 0600 rather than 000 under Unix.
3853
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003854- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3855 argument in python 2.5, this broke code that subclassed Popen to include its
3856 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3865
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003866- Issue #2235: the C API function PyObject_HashNotImplemented and its
3867 interaction with the tp_hash slot (added in 2.6b2) are now documented
3868
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003869- Issue #643841: The language reference now provides more detailed
3870 coverage of the lookup process for special methods. The disclaimers
3871 regarding lack of coverage of new-style classes have also been
3872 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003880Core and Builtins
3881-----------------
3882
Georg Brandl3e483f62008-07-16 22:57:41 +00003883- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3884 its methods now allow for items objects that can be converted to
3885 an integer using operator.index().
3886
Mark Dickinson64b7e502008-07-16 09:40:03 +00003887- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3888 produced a ValueError instead of giving the correct float.
3889
Eric Smitha5fa5a22008-07-16 00:11:49 +00003890- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3891 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3892
Mark Dickinson7103aa42008-07-15 19:08:33 +00003893- Issue #3008: the float type has a new instance method 'float.hex'
3894 and a new class method 'float.fromhex' to convert floating-point
3895 numbers to and from hexadecimal strings, respectively.
3896
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003897- Issue #2235: __hash__ is once again inherited by default. To allow
3898 collections.Hashable to remain meaningful in the presence of the
3899 default hash implementation (object.__hash__), it is now possible
3900 to explicit block inheritance of hash by setting __hash__=None at
3901 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3902 level.
3903
Nick Coghlanb028f502008-07-13 14:52:36 +00003904- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3905 the parent module cannot be found while performing an absolute import.
3906 This means that an incorrectly defined __package__ attribute will
3907 now only prevent relative imports in that module rather than causing
3908 all imports from that module to fail.
3909
Nick Coghlan14ff9942008-07-08 14:21:42 +00003910- Issue #2517: Allow unicode messages in Exceptions again by correctly
3911 bypassing the instance dictionary when looking up __unicode__ on
3912 new-style classes.
3913
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003914- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3915 set to a custom object whose write() method happens to install
3916 another file in sys.stdout.
3917
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003918- Issue #3088: Corrected a race condition in classes derived from
3919 threading.local: the first member set by a thread could be saved in
3920 another thread's dictionary.
3921
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003922- Issue #3004: Minor change to slice.indices(): the start and stop
3923 arguments are now treated identically, making the behaviour easier
3924 to describe and understand. For example, slice(None, -10,
3925 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3926 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3927 10, -1).
3928
Georg Brandl278fc502008-07-19 12:46:12 +00003929- Issue #3219: Calling a function with repeated keyword arguments,
3930 f(a=2, a=23), would not cause a syntax error. This was a regression
3931 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003932
Georg Brandl278fc502008-07-19 12:46:12 +00003933- Issue #2862: Make int and float freelist management consistent with
3934 other freelists. Changes their CompactFreeList apis into
3935 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003936

3939
Thomas Heller57adf222008-08-14 19:10:48 +00003940- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3941 api functions without holding the GIL, which could lead to a fatal
3942 error when they failed.
3943
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003944- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3953 ForkingPickler.register() to resolve conflict with ctypes.
3954
Vinay Sajip51e65192008-07-18 09:01:10 +00003955- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003956
Thomas Heller880f5292008-07-15 19:39:38 +00003957- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3958 a valid dlerror() message.
3959
Thomas Heller2bad6572008-07-15 17:19:50 +00003960- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3961 incomplete structure was created.
3962
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003963- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00003965- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3966
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003967- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003968
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003969- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3970 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003971 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003972 content-length. The problem had been corrected in the 2.4 branch, but never
3973 merged into trunk.
3974
Georg Brandle78fbcc2008-07-05 10:13:36 +00003975- Issue #2663: add filtering capability to shutil.copytree().

4380 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004381 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004382
4383 This is controlled by the configure argument ``--with-universal-archs``:
4384
4385 - ``--with-universal-archs=all``: install 4-way universal
4386
4387 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4388
4389 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4390
4391 This option should be used in combination with ``--enable-universalsdk=``.
4392
4393 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 +00004443- Issue #1631171: Re-implement the 'warnings' module in C (the
4444 original Python code has been kept as backup). This will allow for
4445 using the 'warning's machinery in such places as the parser where
4446 use of pure Python code is not possible. Both the ``showarning()``
4447 and ``formatwarning()`` gain an optional 'line' argument which is
4448 not called by default for backwards-compatibility reasons. Setting
4449 ``warnings.showwarning()`` to an implementation that lacks support
4450 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004513- Issue #2550: The approach used by client/server code for obtaining
4514 ports to listen on in network-oriented tests has been refined in an
4515 effort to facilitate running multiple instances of the entire
4516 regression test suite in parallel without issue.
4517 test_support.bind_port() has been fixed such that it will always
4518 return a unique port -- which wasn't always the case with the
4519 previous implementation, especially if socket options had been set
4520 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4521 new implementation of bind_port() will actually raise an exception
4522 if it is passed an AF_INET/SOCK_STREAM socket with either the
4523 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4524 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4525 the socket it's been passed. This currently only applies to
4526 Windows. This option prevents any other sockets from binding to the
4527 host/port we've bound to, thus removing the possibility of the
4528 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4529 when a second SOCK_STREAM socket binds and accepts to a host/port
4530 that's already been bound by another socket. The optional preferred
4531 port parameter to bind_port() has been removed. Under no
4532 circumstances should tests be hard coding ports!
4533
4534 test_support.find_unused_port() has also been introduced, which will
4535 pass a temporary socket object to bind_port() in order to obtain an
4536 unused port. The temporary socket object is then closed and
4537 deleted, and the port is returned. This method should only be used
4538 for obtaining an unused port in order to pass to an external program
4539 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4540 a parameter to a server-oriented class that doesn't give you direct
4541 access to the underlying socket used.
4542
4543 Finally, test_support.HOST has been introduced, which should be used

4820-----------------
4821
Fred Drakea8ee94b2008-03-01 02:45:07 +00004822- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004823 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004824
Georg Brandlad61bc82008-02-23 15:11:18 +00004825- Issue #2067: file.__exit__() now calls subclasses' close() method.
4826
4827- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004828
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004829- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00004830 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00004831
Eric Smitha73fbe72008-02-23 03:09:44 +00004832- Added the future_builtins module, which contains hex() and oct().
4833 These are the PEP 3127 version of these functions, designed to be
4834 compatible with the hex() and oct() builtins from Python 3.0. They
4835 differ slightly in their output formats from the existing, unchanged
4836 Python 2.6 builtins. The expected usage of the future_builtins
4837 module is:
4838 from future_builtins import hex, oct
4839
Eric Smith7ef40bf2008-02-20 23:34:22 +00004840- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4841 exponents for exponents with absolute value < 100. Follows C99
4842 standard. This is a change on Windows, which would use 3 digits.
4843 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4844 so that any alterations it does to the resulting string will be
4845 available in stringlib/formatter.h (for float.__format__).
4846
Eric Smith5a3c1352008-02-19 13:21:56 +00004847- Implemented PEP 3101, Advanced String Formatting. This adds a new
4848 builtin format(); a format() method for str and unicode; a
4849 __format__() method to object, str, unicode, int, long, float, and
4850 datetime; the class string.Formatter; and the C API
4851 PyObject_Format().
4852
Georg Brandl3ee81df2008-05-17 18:14:43 +00004853- Fixed several potential crashes, all caused by specially crafted
4854 __del__ methods exploiting objects in temporarily inconsistent
4855 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004856
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004857- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004858 prevent a possible crash: an Abstract Base Class would try to access
4859 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004860
Georg Brandl3ee81df2008-05-17 18:14:43 +00004861- Fixed repr() and str() of complex numbers with infinity or nan as
4862 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004863
Georg Brandl3ee81df2008-05-17 18:14:43 +00004864- Clear all free lists during a gc.collect() of the highest generation
4865 in order to allow pymalloc to free more arenas. Python may give back
4866 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004867
Georg Brandl3ee81df2008-05-17 18:14:43 +00004868- Issue #2045: Fix an infinite recursion triggered when printing a
4869 subclass of collections.defaultdict, if its default_factory is set
4870 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004871
Christian Heimesf75dbef2008-02-08 00:11:31 +00004872- Fixed a minor memory leak in dictobject.c. The content of the free
4873 list was not freed on interpreter shutdown.
4874
Georg Brandl21e99f42010-03-07 15:23:59 +00004875- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004876 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004877
Georg Brandl3ee81df2008-05-17 18:14:43 +00004878- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4879 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004880 to compact the internal free lists of pre-allocted ints and floats.
4881
Georg Brandl3ee81df2008-05-17 18:14:43 +00004882- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4883 calls. Python expected the return type int but the fork familie
4884 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004885
Georg Brandl3ee81df2008-05-17 18:14:43 +00004886- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4887 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004888
Georg Brandl3ee81df2008-05-17 18:14:43 +00004889- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4890 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004891
Georg Brandl3ee81df2008-05-17 18:14:43 +00004892- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4893 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004894
Georg Brandl3ee81df2008-05-17 18:14:43 +00004895- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4896 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004897
Georg Brandl3ee81df2008-05-17 18:14:43 +00004898- Patch #1473257: generator objects gain a gi_code attribute. This is
4899 the same object as the func_code attribute of the function that
4900 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004901
Georg Brandl3ee81df2008-05-17 18:14:43 +00004902- Issue #1920: "while 0" statements were completely removed by the
4903 compiler, even in the presence of an "else" clause, which is
4904 supposed to be run when the condition is false. Now the compiler
4905 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004906
Guido van Rossumeead05f2008-01-24 18:21:02 +00004907- A few crashers fixed: weakref_in_del.py (issue #1377858);
4908 loosing_dict_ref.py (issue #1303614, test67.py);
4909 borrowed_ref_[34].py (not in tracker).
4910
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004911- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004912 suppressed while an extension is loaded by calling SetErrorMode in
4913 dynload_win.c. The error is still reported properly.
4914
Georg Brandl3ee81df2008-05-17 18:14:43 +00004915- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004916 several extension methods and modules do not work without unicode
4917 support.
4918
Georg Brandl26543b12008-01-21 18:36:51 +00004919- Issue #1882: when compiling code from a string, encoding cookies in the
4920 second line of code were not always recognized correctly.
4921
Georg Brandl14404b62008-01-19 19:27:05 +00004922- Issue #1679: "0x" was taken as a valid integer literal.
4923
Georg Brandl6caad7d2008-01-26 14:19:22 +00004924- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004925 added.
4926
Christian Heimesc94e2b52008-01-14 04:13:37 +00004927- sys.float_info / PyFloat_GetInfo: The floating point information
4928 object was converted from a dict to a specialized structseq object.
4929
Georg Brandl3ee81df2008-05-17 18:14:43 +00004930- Patch #1816: Added sys.flags structseq. It exposes the status of
4931 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004932
Georg Brandl3ee81df2008-05-17 18:14:43 +00004933- Objects/structseq.c: Implemented new structseq representation. The
4934 patch makes structseqs (e.g. the return value of os.stat) more
4935 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004936
Georg Brandl3ee81df2008-05-17 18:14:43 +00004937- Patch #1700288: added a type attribute cache that caches method
4938 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004939
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004940- Bug #1776: __import__() no longer accepts filenames on any platform.
4941 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004942
Georg Brandlaed6c662008-01-07 17:25:53 +00004943- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4944
Georg Brandl3ee81df2008-05-17 18:14:43 +00004945- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4946 envvar and sys.dont_write_bytecode attribute. All these can be set
4947 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004948
Georg Brandl3ee81df2008-05-17 18:14:43 +00004949- Improve some exception messages when Windows fails to load an
4950 extension module. Now we get for example '%1 is not a valid Win32
4951 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004952
Georg Brandl3ee81df2008-05-17 18:14:43 +00004953- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004955- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4956 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004957
Christian Heimes0a8143f2007-12-18 23:22:54 +00004958- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004959 and INF. float("nan"), float("inf") and float("-inf") now work on
4960 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004961
Georg Brandl3ee81df2008-05-17 18:14:43 +00004962- Compiler now generates simpler and faster code for dictionary
4963 literals. The oparg for BUILD_MAP now indicates an estimated
4964 dictionary size. There is a new opcode, STORE_MAP, for adding
4965 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004966
Georg Brandl3ee81df2008-05-17 18:14:43 +00004967- Issue #1638: %zd configure test fails on Linux.

4977
Nick Coghlanef01d822007-12-03 12:55:17 +00004978- PEP 366: Allow explicit relative imports when executing modules
4979 inside packages with the -m switch via a new module level
4980 __package__ attribute.
4981
Georg Brandl3ee81df2008-05-17 18:14:43 +00004982- Issue #1402: Fix a crash on exit, when another thread is still
4983 running, and if the deallocation of its frames somehow calls the
4984 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004985

Georg Brandl3ee81df2008-05-17 18:14:43 +00004999- Issue #1265: Fix a problem with sys.settrace, if the tracing
5000 function uses a generator expression when at the same time the
5001 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005002
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005003- sets and frozensets now have an isdisjoint() method.
5004
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005005- optimize the performance of builtin.sum().
5006
Neal Norwitz44f326e2007-10-05 05:29:17 +00005007- Fix warnings found by the new version of the Coverity checker.
5008
Georg Brandl21e99f42010-03-07 15:23:59 +00005009- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005010 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5011 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005012
Georg Brandl3ee81df2008-05-17 18:14:43 +00005013- Issue #1686386: Tuple's tp_repr did not take into account the
5014 possibility of having a self-referential tuple, which is possible
5015 from C code. Nor did object's tp_str consider that a type's tp_str
5016 could do something that could lead to an inifinite recursion.
5017 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5018 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005019
Georg Brandl3ee81df2008-05-17 18:14:43 +00005020- Issue #1164: It was possible to trigger deadlock when using the
5021 'print' statement to write to a file since the GIL was not released
5022 as needed. Now PyObject_Print() does the right thing along with
5023 various tp_print implementations of the built-in types and those in
5024 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005025
Georg Brandl3ee81df2008-05-17 18:14:43 +00005026- Issue #1147: Exceptions were directly allowing string exceptions in
5027 their throw() method even though string exceptions no longer
5028 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005029

Brett Cannon1e534b52007-09-07 04:18:30 +00005033- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005034 PyObject_Call() never calling back out to Python code to trigger
5035 recursion depth updates/checks. Required the creation of a static
5036 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005054 __*__ attributes. (Some already existed, e.g., __doc__ and
5055 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005056

5065 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005073 setting a plain string, ie don't expand to single letter identifiers.
5074
Raymond Hettinger13936692007-04-11 18:40:58 +00005075- Request #1191699: Slices can now be pickled.

5085
Guido van Rossum143b5642007-03-23 04:58:42 +00005086- Bug #1683368: The object.__init__() and object.__new__() methods are
5087 now stricter in rejecting excess arguments. The only time when
5088 either allows excess arguments is when it is not overridden and the
5089 other one is. For backwards compatibility, when both are
5090 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005091 warning later). Also, type.__init__() insists on the same signature
5092 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005093
Georg Brandl3ee81df2008-05-17 18:14:43 +00005094- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5095 object to complex using its __complex__() method before falling back
5096 to the __float__() method. Therefore, the functions in the cmath
5097 module now can operate on objects that define a __complex__()
5098 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005116- Bug #1678647: write a newline after printing an exception in any
5117 case, even when converting the value to a string failed.
5118
Georg Brandl871f1bc2007-03-12 13:17:36 +00005119- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005120 its argument, if it exists. If not, it will work like before. This
5121 allows customizing the output of dir() in the presence of a
5122 __getattr__().

5132 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00005134- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005135 makes the filenames the warning module prints much more sensible
5136 when a PYTHONSTARTUP file is used.

5150 sq_ass_slice instead of the sq_slice slot.
5151
Georg Brandl3ee81df2008-05-17 18:14:43 +00005152- When printing an unraisable error, don't print exceptions. before

5781 incompatibility since it never made sense with ordinary subclasses
5782 -- the failure just occurred later, with a more cumbersome
5783 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006064- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6065 with RFC 3207 and forgets any knowledge obtained from the server not
6066 obtained from the TLS negotiation itself. Patch contributed by Bill
6067 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006068
Georg Brandl3ee81df2008-05-17 18:14:43 +00006069- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006070 that the SMTP.starttls() caller no longer needs to call ehlo()
6071 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006072 does not claim to support starttls. Adds the
6073 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6154 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6155 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00006172 time so that opening a database previously created with the DB_DUP
6173 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6174 opens. Specifically: dictionary assignment to a DB object will
6175 replace all values for a given key when the database allows
6176 duplicate values. DB users should use DB.put(k, v) when they want
6177 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006178

6184 characters with ASCII value less than 32. Also, it correctly quotes
6185 dots only if they occur on a single line, as opposed to the previous
6186 behavior of quoting dots if they are the second character of any
6187 line.

Matthias Kloseeb8ff672007-08-02 21:33:13 +00006502- Allow Emacs 22 for building the documentation in info format.
Neal Norwitz92422fb2006-08-18 03:57:54 +00006503
Georg Brandl3ee81df2008-05-17 18:14:43 +00006504- Makefile.pre.in(buildbottest): Run an optional script
6505 pybuildbot.identify to include some information about the build
6506 environment.

Neal Norwitz92422fb2006-08-18 03:57:54 +00006509C API
6510-----
6511
Georg Brandl3ee81df2008-05-17 18:14:43 +00006512- Unified naming convention for free lists and their limits. All free
6513 lists in Object/ are named ``free_list``, the counter ``numfree``
6514 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6515 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006516
Georg Brandl3ee81df2008-05-17 18:14:43 +00006517- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6518 to ``PyTuple_SetItem``, it can be used to populate a brand new
6519 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006520
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006521- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006522
Georg Brandl3ee81df2008-05-17 18:14:43 +00006523- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6524 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6525 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006526
6527- Patch #1720595: add T_BOOL to the range of structmember types.
6528
6529- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6530 ``PyFloat_GetInfo()`` to the float API.
6531
Georg Brandl3ee81df2008-05-17 18:14:43 +00006532- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6533 of w# format code incorrectly truncated the length to an int, even
6534 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6535 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006536
Georg Brandl3ee81df2008-05-17 18:14:43 +00006537- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6538 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006539
Georg Brandl3ee81df2008-05-17 18:14:43 +00006540- PEP 3123: Provide forward compatibility with Python 3.0, while
6541 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6542 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006543
Georg Brandl3ee81df2008-05-17 18:14:43 +00006544- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6545 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006546
6547- Patch #1733960: Allow T_LONGLONG to accept ints.
6548
6549- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6550
Christian Heimes000a0742008-01-03 22:16:32 +00006551- Added a new API function ``PyImport_ImportModuleNoBlock``.
6552
Georg Brandl6caad7d2008-01-26 14:19:22 +00006553- Bug #1637022: Prefix AST symbols with _Py_.
6554
6555- Fix some leftovers from the conversion from int to Py_ssize_t
6556 (relevant to strings and sequences of more than 2**31 items).
6557
6558- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6559 outside of pystate.c and should not be necessary.
6560
Georg Brandl3ee81df2008-05-17 18:14:43 +00006561- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6562 absolute imports. In earlier versions they might have used relative
6563 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006564
Georg Brandl3ee81df2008-05-17 18:14:43 +00006565- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6566 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006567
Georg Brandl3ee81df2008-05-17 18:14:43 +00006568- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6569 macro so it can be used as an expression.

6574
Georg Brandl3ee81df2008-05-17 18:14:43 +00006575- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6576 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6577 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6578 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006579
Georg Brandl3ee81df2008-05-17 18:14:43 +00006580- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
6581 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006593- Removed the macfs module. It had been deprecated since Python 2.5.
6594 This lead to the deprecation of macostools.touched() as it relied
6595 solely on macfs and was a no-op under OS X.
