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.

Florent Xicluna172e15f2010-08-09 20:02:00 +000029- Issue #8530: Prevent stringlib fastsearch from reading beyond the front
30 of an array.
31
Raymond Hettinger3ad323e2010-08-06 10:18:56 +000032- Issue #83755: Implicit set-to-frozenset conversion was not thread-safe.
33
Mark Dickinsonaad57bd2010-08-01 10:45:15 +000034- Issue #9416: Fix some issues with complex formatting where the
35 output with no type specifier failed to match the str output:
36
37 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
38 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
39
Antoine Pitrou32669782010-07-11 12:14:05 +000040- Issue #7616: Fix copying of overlapping memoryview slices with the Intel

45
Vinay Sajip546885e2010-09-25 17:42:36 +000046- Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler.
47
Alexander Belopolsky517185e2010-09-24 18:14:18 +000048- Issue #9936: Fixed executable lines' search in the trace module.
49
Antoine Pitrou2c7d6852010-09-23 19:55:24 +000050- Issue #9928: Properly initialize the types exported by the bz2 module.
51
Antoine Pitrou6391b342010-09-14 18:48:19 +000052- Issue #9854: The default read() implementation in io.RawIOBase now
53 handles non-blocking readinto() returning None correctly.
54
Antoine Pitrouf7f390a2010-09-14 14:37:18 +000055- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
56 SSLSocket.sendto() to match the corresponding socket methods. Also,
57 fix various SSLSocket methods to raise socket.error rather than an
58 unhelpful TypeError when called on an unconnected socket. Original patch
59 by Andrew Bennetts.
60
Raymond Hettinger74f869e2010-09-13 22:14:36 +000061- Issue #9826: OrderedDict.__repr__ can now handle self-referential
62 values: d['x'] = d.
63

Victor Stinner46287f52010-09-13 20:31:34 +000065
Antoine Pitroue4195e82010-09-12 14:56:27 +000066- Issue #9837: The read() method of ZipExtFile objects (as returned by
67 ZipFile.open()) could return more bytes than requested.
68
Raymond Hettinger20397532010-09-12 02:11:45 +000069- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
70 This prevents user-created self-referencing ordered dictionaries from
71 becoming permanently uncollectable GC garbage. The downside is that
72 removing __del__ means that the internal doubly-linked list has to wait for
73 GC collection rather than freeing memory immediately when the refcnt drops
74 to zero.
75
Raymond Hettingerffd2a422010-09-10 10:47:22 +000076- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
77 different internal state for small values of n. Fixed by salting the
78 value.
79
Antoine Pitrouc818ed42010-09-07 21:40:25 +000080- Issue #9792: In case of connection failure, socket.create_connection()
81 would swallow the exception and raise a new one, making it impossible
82 to fetch the original errno, or to filter timeout errors. Now the
83 original error is re-raised.
84
Antoine Pitrouf4f61712010-09-07 16:34:47 +000085- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
86 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
87 be updated back after the system call. Original patch by Brian Brazil.
88
Antoine Pitroudca9de92010-09-04 17:52:26 +000089- Issue #1100562: Fix deep-copying of objects derived from the list and
90 dict types. Patch by Michele Orrù and Björn Lindqvist.
91
Fred Drakea1e627d2010-09-03 03:55:50 +000092- Issue #7005: Fixed output of None values for RawConfigParser.write and
93 ConfigParser.write.
94
Daniel Stutzbach66c981b2010-08-31 20:29:39 +000095- Issue #808164: Fixed socket.close to avoid references to globals, to
96 avoid issues when socket.close is called from a __del__ method.
97
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +000098- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
99 falling into recursion.
100
R. David Murray7c4bf552010-08-25 01:45:57 +0000101- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
102 character years even if the message contains RFC822 two character years.
103
Daniel Stutzbach91287322010-08-24 21:09:30 +0000104- Issue #8750: Fixed MutableSet's methods to correctly handle
105 reflexive operations, namely x -= x and x ^= x.
106
Victor Stinnercaafd772010-09-08 10:51:01 +0000107- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000108 error handling when accepting a new connection.
109
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000110- Issue #658749: asyncore's connect() method now correctly interprets winsock
111 errors.
112
Vinay Sajip1ddd51f2010-08-23 17:50:30 +0000113- Issue #9501: Fixed logging regressions in cleanup code.
114

116 module now correctly return a set. (Patch by Eli Bendersky.)
117
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000118- Issue #9617: Signals received during a low-level write operation aren't
119 ignored by the buffered IO layer anymore.
120
Benjamin Peterson52c36052010-08-21 03:03:22 +0000121- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
122 are not held onto after they are deleted elsewhere.
123
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000124- Issue #9626: the view methods for collections.OrderedDict() were returning
125 the unordered versions inherited from dict. Those methods are now
126 overridden to provide ordered views.
127
Éric Araujo0389ae62010-08-14 03:07:46 +0000128- Issue #8688: MANIFEST files created by distutils now include a magic
129 comment indicating they are generated. Manually maintained MANIFESTs
130 without this marker will not be overwritten or removed.
131
Antoine Pitroue1436d12010-08-12 15:25:51 +0000132- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
133 and a BadZipfile error is raised if it doesn't match (as used to be the
134 case in Python 2.5 and earlier).
135
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000136- Issue #9550: a BufferedReader could issue an additional read when the
137 original read request had been satisfied, which could block indefinitely

139 patch by Jason V. Miller.
140
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000141- Issue #9551: Don't raise TypeError when setting the value to None for

145 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
146
Antoine Pitrou99009162010-08-09 22:51:24 +0000147- Issue #3757: thread-local objects now support cyclic garbage collection.
148 Thread-local objects involved in reference cycles will be deallocated
149 timely by the cyclic GC, even if the underlying thread is still running.
150
Florent Xicluna2f1b1ff2010-08-09 20:46:49 +0000151- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the

Senthil Kumarane677ecf2010-08-08 11:56:31 +0000159- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
160 This is how it is supposed to work, wget and curl do the same. Previous
161 behavior was wrong.
162
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +0000163- Issue #2944: asyncore doesn't handle connection refused correctly.

245
Victor Stinner8b0d84e2010-07-24 02:51:49 +0000246- Issue #9032: XML-RPC client retries the request on EPIPE error. The EPIPE
247 error occurs when the server closes the socket and the client sends a big
248 XML-RPC request.
249

318 compared to other unix systems. In particular, os.getgroups() does
319 not reflect any changes made using os.setgroups() but basicly always

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000501- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
502 start byte and the continuation byte(s) are now considered invalid, instead
503 of the number of bytes specified by the start byte.
504 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
505 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
506 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

517 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

660 non-float non-integer argument is now converted to an integer (if possible)

715 trapped, the specification determines the order in which the signals should be
716 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +0000861- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000862 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
863 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
864 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

884Core and Builtins
885-----------------
886
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000887- Issue #7301: Add environment variable $PYTHONWARNINGS.
888
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000889- Issue #8329: Don't return the same lists from select.select when no fds are
890 changed.
891
Georg Brandlfee0f442010-05-22 21:26:21 +0000892- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000893 on 64-bit machines. The shift count for either left or right shift is
894 permitted to be up to sys.maxsize.
895
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000896- Ensure that tokenization of identifiers is not affected by locale.
897
Georg Brandlfee0f442010-05-22 21:26:21 +0000898- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000899
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000900- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
901
Georg Brandlfee0f442010-05-22 21:26:21 +0000902- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
903 with a non-empty format string. This is an effort to future-proof user
904 code. If a derived class does not currently implement __format__ but later
905 adds its own __format__, it would most likely break user code that had
906 supplied a format string. This will be changed to a DeprecationWaring in
907 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000908
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000909- Issue #8268: Old-style classes (not just instances) now support weak

933
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000934- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000935 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
936 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000937
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000938- Issue #8310: Allow dis to examine new style classes.
939
Georg Brandlfee0f442010-05-22 21:26:21 +0000940- Issue #8257: The Decimal construct now accepts a float instance directly,
941 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000942
943 >>> Decimal(1.1)
944 Decimal('1.100000000000000088817841970012523233890533447265625')
945
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000946- collections.Counter() now supports a subtract() method.
947
Georg Brandlfee0f442010-05-22 21:26:21 +0000948- The functools module now has a total_ordering() class decorator to simplify
949 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000950
Georg Brandlfee0f442010-05-22 21:26:21 +0000951- The functools module also adds cmp_to_key() as a tool to transition old-style
952 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000953
Georg Brandlfee0f442010-05-22 21:26:21 +0000954- Issue #8294: The Fraction constructor now accepts Decimal and float instances
955 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000956
Georg Brandlfee0f442010-05-22 21:26:21 +0000957- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
958 InvalidOperation instead of returning False. (Comparisons involving a quiet
959 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
960 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000961
Georg Brandlfee0f442010-05-22 21:26:21 +0000962- Issue #2531: Comparison operations between floats and Decimal instances now
963 return a result based on the numeric values of the operands; previously they
964 returned an arbitrary result based on the relative ordering of id(float) and
965 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000966
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000967- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000968 argument `-` which tells it to read files to compile from stdin. Each line is
969 read on demand and the named file is compiled immediately. (Original patch by
970 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000971
Georg Brandlfee0f442010-05-22 21:26:21 +0000972- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000975- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
976 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000977 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000978
Georg Brandlfee0f442010-05-22 21:26:21 +0000979- Comparisons using one of <, <=, >, >= between a complex instance and a
980 Fractions instance now raise TypeError instead of returning True/False. This
981 makes Fraction <=> complex comparisons consistent with int <=> complex, float
982 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000983
Michael Foorde6410c52010-03-29 20:04:23 +0000984- Addition of ``WeakSet`` to the ``weakref`` module.

992
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000993- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000994 didn't support chflags() (for example ZFS under FreeBSD). The error is now
995 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000996
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000997- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
998 deprecated.
999
Georg Brandlfee0f442010-05-22 21:26:21 +00001000- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1001 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001002

1008 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001009
Georg Brandlfee0f442010-05-22 21:26:21 +00001010- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001037- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001038 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1039 log file to compute the next rollover time. If the log file does not exist,
1040 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001041
Georg Brandlba83f822010-03-14 09:50:54 +00001042- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00001050- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1051 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1052 This is a behavior change, so email's minor version number is now bumped, to
1053 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001081- Issue #8300: When passing a non-integer argument to struct.pack with any
1082 integer format code, struct.pack first attempts to convert the non-integer
1083 using its __index__ method. If that method is non-existent or raises

1085
Georg Brandlba83f822010-03-14 09:50:54 +00001086- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1087 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1088 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001089 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1090 inconsistent: __int__ was used for some integer codes but not for others, and
1091 the set of integer codes for which it was used differed between native packing
1092 and standard packing.)

1493-----------------
1494
Georg Brandlba83f822010-03-14 09:50:54 +00001495- The ``__complex__()`` method is now looked up on the class of instances to
1496 make it consistent with other special methods.

1500
Mark Dickinson1b34d252010-01-01 17:27:30 +00001501- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001502 DeprecationWarning when passed a float argument where an integer was expected.
1503 These functions and methods now raise TypeError instead. The majority of the
1504 effects of this change are in the extension modules, but some core functions
1505 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1506 and many unicode/str methods.

1520 of integers: the result of a/b is now correctly rounded for ints a and b (at
1521 least on IEEE 754 platforms), and in particular does not depend on the
1522 internal representation of a long.

1530
Georg Brandlba83f822010-03-14 09:50:54 +00001531 These executables now work properly with the arch(1) command: ``arch -ppc

1672 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1673 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001674
Georg Brandlba83f822010-03-14 09:50:54 +00001675- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1676 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001677
Georg Brandlba83f822010-03-14 09:50:54 +00001678- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001688
Georg Brandlba83f822010-03-14 09:50:54 +00001689- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1690 decimal string that's guaranteed to round back to x under correct rounding
1691 (with round-half-to-even rounding mode). Previously it gave a string based on
1692 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1693 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1694 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001695
Georg Brandlba83f822010-03-14 09:50:54 +00001696- Issue #7117: On almost all platforms: float-to-string and string-to-float
1697 conversions within Python are now correctly rounded. Places these conversions
1698 occur include: str for floats and complex numbers; the float and complex
1699 constructors; old-style and new-style numeric formatting; serialization and
1700 deserialization of floats and complex numbers using marshal, pickle and json;
1701 parsing of float and imaginary literals in Python code; Decimal-to-float
1702 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001703
Georg Brandlba83f822010-03-14 09:50:54 +00001704 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1705 providing correctly-rounded strtod and dtoa C functions. This code is
1706 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1707 the C compiler. There may be a small number of platforms on which correct
1708 operation of this code cannot be guaranteed, so the code is not used: notably,
1709 this applies to platforms where the C double format is not IEEE 754 binary64,
1710 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1711 and Python's configure script is unable to determine how to change the FPU
1712 precision. On these platforms conversions use the platform strtod and dtoa,
1713 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001714
Georg Brandlba83f822010-03-14 09:50:54 +00001715- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1716 uses the correctly-rounded string <-> float conversions described above (when
1717 available), and so produces correctly rounded results that will display nicely
1718 under the float repr. There are two related small changes: (1) round now
1719 accepts any class with an ``__index__()`` method for its second argument (but
1720 no longer accepts floats for the second argument), and (2) an excessively
1721 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1722 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001865 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1866 (2) parsing of strings representing infinities and nans was locale aware; and
1867 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001869- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1870 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1871 but with at least one decimal point and with a default precision
1872 of 12. Previously, the behavior the same but with a default precision of 6.
1873 This more closely matches ``str()``, and reduces surprises when adding
1874 alignment flags to the empty presentation type. This also affects the new
1875 complex.__format__ in the same way.
1876
1877- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Benjamin Petersonfe231b02008-12-29 17:47:42 +00002035- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
2036 systems.
2037
Georg Brandl6425a2f2008-12-28 11:54:53 +00002038- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002039 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002040
Skip Montanarof205c132008-12-23 03:30:15 +00002041- Added test case to ensure attempts to read from a file opened for writing
2042 fail.
2043
Georg Brandlba83f822010-03-14 09:50:54 +00002044- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print

Georg Brandlba83f822010-03-14 09:50:54 +00002058- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2059 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2060 instances. On a typical machine this saves 3 bytes of memory (on average) per
2061 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002063- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2064 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2065 instead of throwing a MemoryError.
2066
Georg Brandlba83f822010-03-14 09:50:54 +00002067- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00002070- Issue #4367: Python would segfault during compiling when the unicodedata
2071 module couldn't be imported and \N escapes were present.
2072
Georg Brandlba83f822010-03-14 09:50:54 +00002073- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2074 file objects with closefd=False. The file descriptor is still kept open but
2075 the file object behaves like a closed file. The ``FileIO`` object also got a
2076 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002078- Issue #4348: Some bytearray methods returned that didn't cause any change to
2079 the bytearray, returned the same bytearray instead of a copy.
2080
Georg Brandlba83f822010-03-14 09:50:54 +00002081- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

2086
Benjamin Petersondcee09d2008-10-31 02:16:05 +00002087- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

Benjamin Petersonbdca9422008-10-26 20:21:13 +00002093- Issue #4209: Enabling unicode_literals and the print_function in the same
2094 __future__ import didn't work.
2095
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002096- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002097 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002098
Georg Brandlba83f822010-03-14 09:50:54 +00002099- On windows, ``os.chdir()`` given unicode was not working if
2100 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2101 this code path is really executed because I cannot move to such directory on
2102 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002103
Georg Brandlba83f822010-03-14 09:50:54 +00002104- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2105 element is temporarily replaced with an equivalent frozenset. But the
2106 eventual KeyError would always report the empty ``frozenset()`` as the missing
2107 key. Now it correctly refers to the initial element.

2125 returned them on 64bit platforms.
2126
Walter Dörwalded960ac2009-05-03 22:36:33 +00002127- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2128 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2129 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2130 of using the replace error handler in PyUnicode_DecodeUTF8().
2131
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002132- Issue #3739: The unicode-internal encoder now reports the number of characters
2133 consumed like any other encoder (instead of the number of bytes).
2134
Georg Brandlba83f822010-03-14 09:50:54 +00002135- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2136 allocator will be automatically disabled when running under Valgrind. This
2137 gives improved memory leak detection when running under Valgrind, while taking
2138 advantage of pymalloc at other times.

3401 should cause a test to be skipped are now done using import_module from test
3402 support, which does the conversion.

3504
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003505- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3506 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3507 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3508 ``printf`` function, whereas PyString_FromFormat has an independent
3509 implementation and uses "%zd" on all platforms for size_t values.
3510 This makes a difference on win64, where ``printf`` needs "%Id" to display
3511 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003513- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3517 object; previously an int would be returned for small values. the __long__
3518 method is allowed to return either an int or a long, but the behaviour of
3519 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003521- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00003527 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003528 was correctly parsed but parsing of subsequent arguments failed.
3529
Vinay Sajip35e3b032008-09-01 14:33:59 +00003530- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003531 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3532 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3533 when given a tuple of classes as second argument, were looking up
3534 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3535 type object.
3536
Neal Norwitz18aa3882008-08-24 05:04:52 +00003537- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003606 warnings.catch_warnings() along with some API cleanup. Expanding the tests

3680-----------------
3681
Guido van Rossumf8402962008-08-20 15:01:50 +00003682- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3683 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3684 extensions do not automatically benefit from the class attribute
3685 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3686 to their tp_flags field if they care. This is a backwards
3687 compatibility feature; in 3.0, all types will use the cache by
3688 default.
3689
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003690- Keyword arguments can now follow starred arguments. (``f(a, *args,
3691 keyword=23)`` is now valid syntax.)
3692
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003693- ctypes function pointers that are COM methods have a boolean True

Georg Brandl1e13ea92008-08-11 09:07:59 +00003700- Issue #3537: Fix an assertion failure when an empty but presized dict
3701 object was stored in the freelist.
3702
Mark Dickinsonb6467572008-08-04 21:30:09 +00003703- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3704 ValueError consistently across platforms.
3705
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003706- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3707 (64bit Unix, for example), unichr() would truncate its argument and return
3708 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3709
Neal Norwitze7d8be82008-07-31 17:17:14 +00003710- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003712- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3713 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3714
Antoine Pitrou92f82162008-07-25 22:22:08 +00003715- Issue #1819: function calls with several named parameters are now on
3716 average 35% faster (as measured by pybench).
3717
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003718- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3719 the python debugger steps into a class statement: the free variables (local
3720 variables defined in an outer scope) would be deleted from the outer scope.
3721
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003722- Issue #2620: Overflow checking when allocating or reallocating memory
3723 was not always being done properly in some python types and extension
3724 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3725 all been updated to perform better checks and places in the code that
3726 would previously leak memory on the error path when such an allocation
3727 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00003734- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3735 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3736
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003737- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3738 version reported by these tools does not necessarily follow the python
3739 version numbering scheme, so the module is less strict when parsing it.
3740
Nick Coghlanf70385a2008-08-18 12:42:46 +00003741- Issue #2235: Added Py3k warnings for types which will become unhashable
3742 under the stricter __hash__ inheritance rules in 3.0. Several types
3743 which did not meet the rules for hash invariants and were already
3744 unhashable in 3.0 have now been explicitly flagged as unhashable in
3745 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3746 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3747
Brett Cannon88f801d2008-08-18 00:46:22 +00003748- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00003779- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3780 since mimetools itself is deprecated. Because modules are cached, all
3781 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3782
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003783- Issue #3134: shutil referenced undefined WindowsError symbol.

3792 a MemoryError rather than silently stop the iteration.
3793
Guido van Rossum59ce9012008-08-09 14:55:34 +00003794- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3795 to _sre.compile() will now be rejected. This should not affect anybody
3796 since the re.compile() function never generates invalid re-bytecode.
3797
Skip Montanaroa032bf42008-08-08 22:52:51 +00003798- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3799 upon first access it can be automatically initialized from the csv file if
3800 it wasn't initialized during instantiation.
3801
Brett Cannon3aa2a492008-08-06 22:28:09 +00003802- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3803 the reload() built-in has been removed.
3804
Brett Cannon7e30b672008-08-04 21:52:25 +00003805- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003806 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003817 asking for a specific length. This problem only affected files opened
3818 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003819

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003843- Issue #3394: zipfile.writestr sets external attributes when passed a
3844 file name rather than a ZipInfo instance, so files are extracted with
3845 mode 0600 rather than 000 under Unix.
3846
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003847- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3848 argument in python 2.5, this broke code that subclassed Popen to include its
3849 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003859- Issue #2235: the C API function PyObject_HashNotImplemented and its
3860 interaction with the tp_hash slot (added in 2.6b2) are now documented
3861
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003862- Issue #643841: The language reference now provides more detailed
3863 coverage of the lookup process for special methods. The disclaimers
3864 regarding lack of coverage of new-style classes have also been
3865 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003873Core and Builtins
3874-----------------
3875
Georg Brandl3e483f62008-07-16 22:57:41 +00003876- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3877 its methods now allow for items objects that can be converted to
3878 an integer using operator.index().
3879
Mark Dickinson64b7e502008-07-16 09:40:03 +00003880- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3881 produced a ValueError instead of giving the correct float.
3882
Eric Smitha5fa5a22008-07-16 00:11:49 +00003883- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3884 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3885
Mark Dickinson7103aa42008-07-15 19:08:33 +00003886- Issue #3008: the float type has a new instance method 'float.hex'
3887 and a new class method 'float.fromhex' to convert floating-point
3888 numbers to and from hexadecimal strings, respectively.
3889
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003890- Issue #2235: __hash__ is once again inherited by default. To allow
3891 collections.Hashable to remain meaningful in the presence of the
3892 default hash implementation (object.__hash__), it is now possible
3893 to explicit block inheritance of hash by setting __hash__=None at
3894 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3895 level.
3896
Nick Coghlanb028f502008-07-13 14:52:36 +00003897- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3898 the parent module cannot be found while performing an absolute import.
3899 This means that an incorrectly defined __package__ attribute will
3900 now only prevent relative imports in that module rather than causing
3901 all imports from that module to fail.
3902
Nick Coghlan14ff9942008-07-08 14:21:42 +00003903- Issue #2517: Allow unicode messages in Exceptions again by correctly
3904 bypassing the instance dictionary when looking up __unicode__ on
3905 new-style classes.
3906
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003907- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3908 set to a custom object whose write() method happens to install
3909 another file in sys.stdout.
3910
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003911- Issue #3088: Corrected a race condition in classes derived from
3912 threading.local: the first member set by a thread could be saved in
3913 another thread's dictionary.
3914
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003915- Issue #3004: Minor change to slice.indices(): the start and stop
3916 arguments are now treated identically, making the behaviour easier
3917 to describe and understand. For example, slice(None, -10,
3918 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3919 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3920 10, -1).
3921
Georg Brandl278fc502008-07-19 12:46:12 +00003922- Issue #3219: Calling a function with repeated keyword arguments,
3923 f(a=2, a=23), would not cause a syntax error. This was a regression
3924 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003925
Georg Brandl278fc502008-07-19 12:46:12 +00003926- Issue #2862: Make int and float freelist management consistent with
3927 other freelists. Changes their CompactFreeList apis into
3928 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003929

3932
Thomas Heller57adf222008-08-14 19:10:48 +00003933- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3934 api functions without holding the GIL, which could lead to a fatal
3935 error when they failed.
3936
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003937- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3946 ForkingPickler.register() to resolve conflict with ctypes.
3947
Vinay Sajip51e65192008-07-18 09:01:10 +00003948- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003950- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3951 a valid dlerror() message.
3952
Thomas Heller2bad6572008-07-15 17:19:50 +00003953- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3954 incomplete structure was created.
3955
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003956- Issue #3339: dummy_thread.acquire() should not return None.

3959
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003960- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003961
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003962- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3963 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003964 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003965 content-length. The problem had been corrected in the 2.4 branch, but never
3966 merged into trunk.
3967
Georg Brandle78fbcc2008-07-05 10:13:36 +00003968- Issue #2663: add filtering capability to shutil.copytree().

4371
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004372- On MacOS X it is now possible to install the framework in 64-bit
4373 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004374 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004375
4376 This is controlled by the configure argument ``--with-universal-archs``:
4377
4378 - ``--with-universal-archs=all``: install 4-way universal
4379
4380 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4381
4382 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4383
4384 This option should be used in combination with ``--enable-universalsdk=``.
4385
4386 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 +00004436- Issue #1631171: Re-implement the 'warnings' module in C (the
4437 original Python code has been kept as backup). This will allow for
4438 using the 'warning's machinery in such places as the parser where
4439 use of pure Python code is not possible. Both the ``showarning()``
4440 and ``formatwarning()`` gain an optional 'line' argument which is
4441 not called by default for backwards-compatibility reasons. Setting
4442 ``warnings.showwarning()`` to an implementation that lacks support
4443 for the ``line`` argument will raise a DeprecationWarning.

4467
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004468- The getpass module has been improved on Unix. It now uses /dev/tty
4469 by default and uses stderr instead of stdout. A GetPassWarning is
4470 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004506- Issue #2550: The approach used by client/server code for obtaining
4507 ports to listen on in network-oriented tests has been refined in an
4508 effort to facilitate running multiple instances of the entire
4509 regression test suite in parallel without issue.
4510 test_support.bind_port() has been fixed such that it will always
4511 return a unique port -- which wasn't always the case with the
4512 previous implementation, especially if socket options had been set
4513 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4514 new implementation of bind_port() will actually raise an exception
4515 if it is passed an AF_INET/SOCK_STREAM socket with either the
4516 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4517 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4518 the socket it's been passed. This currently only applies to
4519 Windows. This option prevents any other sockets from binding to the
4520 host/port we've bound to, thus removing the possibility of the
4521 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4522 when a second SOCK_STREAM socket binds and accepts to a host/port
4523 that's already been bound by another socket. The optional preferred
4524 port parameter to bind_port() has been removed. Under no
4525 circumstances should tests be hard coding ports!
4526
4527 test_support.find_unused_port() has also been introduced, which will
4528 pass a temporary socket object to bind_port() in order to obtain an
4529 unused port. The temporary socket object is then closed and
4530 deleted, and the port is returned. This method should only be used
4531 for obtaining an unused port in order to pass to an external program
4532 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4533 a parameter to a server-oriented class that doesn't give you direct
4534 access to the underlying socket used.
4535
4536 Finally, test_support.HOST has been introduced, which should be used
4537 for the host argument of any relevant socket calls (i.e. bind and
4538 connect).

4813-----------------
4814
Fred Drakea8ee94b2008-03-01 02:45:07 +00004815- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004816 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004817
Georg Brandlad61bc82008-02-23 15:11:18 +00004818- Issue #2067: file.__exit__() now calls subclasses' close() method.
4819
4820- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004821
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004822- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00004823 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00004824
Eric Smitha73fbe72008-02-23 03:09:44 +00004825- Added the future_builtins module, which contains hex() and oct().
4826 These are the PEP 3127 version of these functions, designed to be
4827 compatible with the hex() and oct() builtins from Python 3.0. They
4828 differ slightly in their output formats from the existing, unchanged
4829 Python 2.6 builtins. The expected usage of the future_builtins
4830 module is:
4831 from future_builtins import hex, oct
4832
Eric Smith7ef40bf2008-02-20 23:34:22 +00004833- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4834 exponents for exponents with absolute value < 100. Follows C99
4835 standard. This is a change on Windows, which would use 3 digits.
4836 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4837 so that any alterations it does to the resulting string will be
4838 available in stringlib/formatter.h (for float.__format__).
4839
Eric Smith5a3c1352008-02-19 13:21:56 +00004840- Implemented PEP 3101, Advanced String Formatting. This adds a new
4841 builtin format(); a format() method for str and unicode; a
4842 __format__() method to object, str, unicode, int, long, float, and
4843 datetime; the class string.Formatter; and the C API
4844 PyObject_Format().
4845
Georg Brandl3ee81df2008-05-17 18:14:43 +00004846- Fixed several potential crashes, all caused by specially crafted
4847 __del__ methods exploiting objects in temporarily inconsistent
4848 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004849
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004850- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004851 prevent a possible crash: an Abstract Base Class would try to access
4852 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004853
Georg Brandl3ee81df2008-05-17 18:14:43 +00004854- Fixed repr() and str() of complex numbers with infinity or nan as
4855 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004856
Georg Brandl3ee81df2008-05-17 18:14:43 +00004857- Clear all free lists during a gc.collect() of the highest generation
4858 in order to allow pymalloc to free more arenas. Python may give back
4859 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004860
Georg Brandl3ee81df2008-05-17 18:14:43 +00004861- Issue #2045: Fix an infinite recursion triggered when printing a
4862 subclass of collections.defaultdict, if its default_factory is set
4863 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004864
Christian Heimesf75dbef2008-02-08 00:11:31 +00004865- Fixed a minor memory leak in dictobject.c. The content of the free
4866 list was not freed on interpreter shutdown.
4867
Georg Brandl21e99f42010-03-07 15:23:59 +00004868- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004869 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004870
Georg Brandl3ee81df2008-05-17 18:14:43 +00004871- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4872 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004873 to compact the internal free lists of pre-allocted ints and floats.
4874
Georg Brandl3ee81df2008-05-17 18:14:43 +00004875- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4876 calls. Python expected the return type int but the fork familie
4877 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004878
Georg Brandl3ee81df2008-05-17 18:14:43 +00004879- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4880 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004881
Georg Brandl3ee81df2008-05-17 18:14:43 +00004882- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4883 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004884
Georg Brandl3ee81df2008-05-17 18:14:43 +00004885- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4886 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004887
Georg Brandl3ee81df2008-05-17 18:14:43 +00004888- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4889 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004890
Georg Brandl3ee81df2008-05-17 18:14:43 +00004891- Patch #1473257: generator objects gain a gi_code attribute. This is
4892 the same object as the func_code attribute of the function that
4893 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004894
Georg Brandl3ee81df2008-05-17 18:14:43 +00004895- Issue #1920: "while 0" statements were completely removed by the
4896 compiler, even in the presence of an "else" clause, which is
4897 supposed to be run when the condition is false. Now the compiler
4898 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004899
Guido van Rossumeead05f2008-01-24 18:21:02 +00004900- A few crashers fixed: weakref_in_del.py (issue #1377858);
4901 loosing_dict_ref.py (issue #1303614, test67.py);
4902 borrowed_ref_[34].py (not in tracker).
4903
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004904- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004905 suppressed while an extension is loaded by calling SetErrorMode in
4906 dynload_win.c. The error is still reported properly.
4907
Georg Brandl3ee81df2008-05-17 18:14:43 +00004908- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004909 several extension methods and modules do not work without unicode
4910 support.
4911
Georg Brandl26543b12008-01-21 18:36:51 +00004912- Issue #1882: when compiling code from a string, encoding cookies in the
4913 second line of code were not always recognized correctly.
4914
Georg Brandl14404b62008-01-19 19:27:05 +00004915- Issue #1679: "0x" was taken as a valid integer literal.
4916
Georg Brandl6caad7d2008-01-26 14:19:22 +00004917- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004918 added.
4919
Christian Heimesc94e2b52008-01-14 04:13:37 +00004920- sys.float_info / PyFloat_GetInfo: The floating point information
4921 object was converted from a dict to a specialized structseq object.
4922
Georg Brandl3ee81df2008-05-17 18:14:43 +00004923- Patch #1816: Added sys.flags structseq. It exposes the status of
4924 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004925
Georg Brandl3ee81df2008-05-17 18:14:43 +00004926- Objects/structseq.c: Implemented new structseq representation. The
4927 patch makes structseqs (e.g. the return value of os.stat) more
4928 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004929
Georg Brandl3ee81df2008-05-17 18:14:43 +00004930- Patch #1700288: added a type attribute cache that caches method
4931 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004932
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004933- Bug #1776: __import__() no longer accepts filenames on any platform.
4934 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004935
Georg Brandlaed6c662008-01-07 17:25:53 +00004936- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4937
Georg Brandl3ee81df2008-05-17 18:14:43 +00004938- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4939 envvar and sys.dont_write_bytecode attribute. All these can be set
4940 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004941
Georg Brandl3ee81df2008-05-17 18:14:43 +00004942- Improve some exception messages when Windows fails to load an
4943 extension module. Now we get for example '%1 is not a valid Win32
4944 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004945
Georg Brandl3ee81df2008-05-17 18:14:43 +00004946- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004948- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4949 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004950
Christian Heimes0a8143f2007-12-18 23:22:54 +00004951- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004952 and INF. float("nan"), float("inf") and float("-inf") now work on
4953 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004954
Georg Brandl3ee81df2008-05-17 18:14:43 +00004955- Compiler now generates simpler and faster code for dictionary
4956 literals. The oparg for BUILD_MAP now indicates an estimated
4957 dictionary size. There is a new opcode, STORE_MAP, for adding
4958 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004959
Georg Brandl3ee81df2008-05-17 18:14:43 +00004960- Issue #1638: %zd configure test fails on Linux.

4966 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004967
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004968- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004969 SystemError.
4970
Nick Coghlanef01d822007-12-03 12:55:17 +00004971- PEP 366: Allow explicit relative imports when executing modules
4972 inside packages with the -m switch via a new module level
4973 __package__ attribute.
4974
Georg Brandl3ee81df2008-05-17 18:14:43 +00004975- Issue #1402: Fix a crash on exit, when another thread is still
4976 running, and if the deallocation of its frames somehow calls the
4977 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004978

4988 file can now be directly executed by passing their name to the
4989 interpreter. The directory/zipfile is automatically inserted as the
4990 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004991
Georg Brandl3ee81df2008-05-17 18:14:43 +00004992- Issue #1265: Fix a problem with sys.settrace, if the tracing
4993 function uses a generator expression when at the same time the
4994 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004995
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004996- sets and frozensets now have an isdisjoint() method.
4997
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004998- optimize the performance of builtin.sum().
4999
Neal Norwitz44f326e2007-10-05 05:29:17 +00005000- Fix warnings found by the new version of the Coverity checker.
5001
Georg Brandl21e99f42010-03-07 15:23:59 +00005002- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005003 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5004 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005005
Georg Brandl3ee81df2008-05-17 18:14:43 +00005006- Issue #1686386: Tuple's tp_repr did not take into account the
5007 possibility of having a self-referential tuple, which is possible
5008 from C code. Nor did object's tp_str consider that a type's tp_str
5009 could do something that could lead to an inifinite recursion.
5010 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5011 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005012
Georg Brandl3ee81df2008-05-17 18:14:43 +00005013- Issue #1164: It was possible to trigger deadlock when using the
5014 'print' statement to write to a file since the GIL was not released
5015 as needed. Now PyObject_Print() does the right thing along with
5016 various tp_print implementations of the built-in types and those in
5017 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005018
Georg Brandl3ee81df2008-05-17 18:14:43 +00005019- Issue #1147: Exceptions were directly allowing string exceptions in
5020 their throw() method even though string exceptions no longer
5021 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005022

Brett Cannon1e534b52007-09-07 04:18:30 +00005026- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005027 PyObject_Call() never calling back out to Python code to trigger
5028 recursion depth updates/checks. Required the creation of a static
5029 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005047 __*__ attributes. (Some already existed, e.g., __doc__ and
5048 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005049
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005050- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00005057 "except E as target:". This is to provide forwards compatibility
5058 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005059
Brett Cannon229cee22007-05-05 01:34:02 +00005060- Deprecate BaseException.message as per PEP 352.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005066 setting a plain string, ie don't expand to single letter identifiers.
5067
Raymond Hettinger13936692007-04-11 18:40:58 +00005068- Request #1191699: Slices can now be pickled.

5078
Guido van Rossum143b5642007-03-23 04:58:42 +00005079- Bug #1683368: The object.__init__() and object.__new__() methods are
5080 now stricter in rejecting excess arguments. The only time when
5081 either allows excess arguments is when it is not overridden and the
5082 other one is. For backwards compatibility, when both are
5083 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005084 warning later). Also, type.__init__() insists on the same signature
5085 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005086
Georg Brandl3ee81df2008-05-17 18:14:43 +00005087- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5088 object to complex using its __complex__() method before falling back
5089 to the __float__() method. Therefore, the functions in the cmath
5090 module now can operate on objects that define a __complex__()
5091 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005109- Bug #1678647: write a newline after printing an exception in any
5110 case, even when converting the value to a string failed.
5111
Georg Brandl871f1bc2007-03-12 13:17:36 +00005112- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005113 its argument, if it exists. If not, it will work like before. This
5114 allows customizing the output of dir() in the presence of a
5115 __getattr__().

5125 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005126
Georg Brandlaa2321b2007-03-07 00:40:28 +00005127- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005128 makes the filenames the warning module prints much more sensible
5129 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005130

Georg Brandl0fca97a2007-03-05 22:28:08 +00005142- Patch #1674228: when assigning a slice (old-style), check for the
5143 sq_ass_slice instead of the sq_slice slot.
5144
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145- When printing an unraisable error, don't print exceptions. before

5773 accepted in TestSuite.addTest(). This should cause no
5774 incompatibility since it never made sense with ordinary subclasses
5775 -- the failure just occurred later, with a more cumbersome
5776 exception.

6060 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006061
Georg Brandl3ee81df2008-05-17 18:14:43 +00006062- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006063 that the SMTP.starttls() caller no longer needs to call ehlo()
6064 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006065 does not claim to support starttls. Adds the
6066 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6147 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6148 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00006165 time so that opening a database previously created with the DB_DUP
6166 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6167 opens. Specifically: dictionary assignment to a DB object will
6168 replace all values for a given key when the database allows
6169 duplicate values. DB users should use DB.put(k, v) when they want
6170 to store duplicates; not DB[k] = v.

6177 characters with ASCII value less than 32. Also, it correctly quotes
6178 dots only if they occur on a single line, as opposed to the previous
6179 behavior of quoting dots if they are the second character of any
6180 line.

Neal Norwitz92422fb2006-08-18 03:57:54 +00006502C API
6503-----
6504
Georg Brandl3ee81df2008-05-17 18:14:43 +00006505- Unified naming convention for free lists and their limits. All free
6506 lists in Object/ are named ``free_list``, the counter ``numfree``
6507 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6508 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006509
Georg Brandl3ee81df2008-05-17 18:14:43 +00006510- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6511 to ``PyTuple_SetItem``, it can be used to populate a brand new
6512 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006513
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006514- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006515
Georg Brandl3ee81df2008-05-17 18:14:43 +00006516- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
6517 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6518 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006519
6520- Patch #1720595: add T_BOOL to the range of structmember types.
6521
6522- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6523 ``PyFloat_GetInfo()`` to the float API.
6524
Georg Brandl3ee81df2008-05-17 18:14:43 +00006525- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6526 of w# format code incorrectly truncated the length to an int, even
6527 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6528 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006529
Georg Brandl3ee81df2008-05-17 18:14:43 +00006530- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6531 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006532
Georg Brandl3ee81df2008-05-17 18:14:43 +00006533- PEP 3123: Provide forward compatibility with Python 3.0, while
6534 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6535 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006536
Georg Brandl3ee81df2008-05-17 18:14:43 +00006537- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6538 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006539
6540- Patch #1733960: Allow T_LONGLONG to accept ints.
6541
6542- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
6543
Christian Heimes000a0742008-01-03 22:16:32 +00006544- Added a new API function ``PyImport_ImportModuleNoBlock``.
6545
Georg Brandl6caad7d2008-01-26 14:19:22 +00006546- Bug #1637022: Prefix AST symbols with _Py_.
6547
6548- Fix some leftovers from the conversion from int to Py_ssize_t
6549 (relevant to strings and sequences of more than 2**31 items).
6550
6551- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6552 outside of pystate.c and should not be necessary.
6553
Georg Brandl3ee81df2008-05-17 18:14:43 +00006554- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6555 absolute imports. In earlier versions they might have used relative
6556 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006557
Georg Brandl3ee81df2008-05-17 18:14:43 +00006558- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6559 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006560
Georg Brandl3ee81df2008-05-17 18:14:43 +00006561- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
6562 macro so it can be used as an expression.

6567
Georg Brandl3ee81df2008-05-17 18:14:43 +00006568- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6569 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6570 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6571 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006572
Georg Brandl3ee81df2008-05-17 18:14:43 +00006573- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
6574 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006586- Removed the macfs module. It had been deprecated since Python 2.5.
6587 This lead to the deprecation of macostools.touched() as it relied
6588 solely on macfs and was a no-op under OS X.
