579 This prevents user-created self-referencing ordered dictionaries from
580 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001042- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1043 start byte and the continuation byte(s) are now considered invalid, instead
1044 of the number of bytes specified by the start byte.
1045 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1046 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1047 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001056- Issue #8748: Fix two issues with comparisons between complex and integer
1057 objects. (1) The comparison could incorrectly return True in some cases
1058 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1059 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00001200- Issue #1533: Fix inconsistency in range function argument processing: any
1201 non-float non-integer argument is now converted to an integer (if possible)
1202 using its __int__ method. Previously, only small arguments were treated this
1203 way; larger arguments (those whose __int__ was outside the range of a C long)
1204 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00001212 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00001213 benefit compared to the dynamic memory allocation fallback. Patch by

1239 messages when accessing undefined class attributes because of the cheap
1240 inheritance with the underlying socket object. The cheap inheritance has been
1241 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00001254- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1255 operation raises multiple signals and more than one of those signals is
1256 trapped, the specification determines the order in which the signals should be
1257 handled. In many cases this order wasn't being followed, leading to the wrong
1258 Python exception being raised.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001428- Issue #7301: Add environment variable $PYTHONWARNINGS.
1429
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001430- Issue #8329: Don't return the same lists from select.select when no fds are
1431 changed.
1432
Georg Brandlfee0f442010-05-22 21:26:21 +00001433- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001434 on 64-bit machines. The shift count for either left or right shift is
1435 permitted to be up to sys.maxsize.
1436
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001437- Ensure that tokenization of identifiers is not affected by locale.
1438
Georg Brandlfee0f442010-05-22 21:26:21 +00001439- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001440
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001441- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1442
Georg Brandlfee0f442010-05-22 21:26:21 +00001443- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1444 with a non-empty format string. This is an effort to future-proof user
1445 code. If a derived class does not currently implement __format__ but later
1446 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001447 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001448 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001449
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001450- Issue #8268: Old-style classes (not just instances) now support weak
1451 references.
1452
Georg Brandlfee0f442010-05-22 21:26:21 +00001453- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
1454 is set.

1462
Victor Stinner66644262010-03-10 22:30:19 +00001463- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001464 (SIGINT). If an error occurs while importing the site module, the error is
1465 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001466 module.

1474
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001475- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001476 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1477 `ssl.OPENSSL_VERSION_NUMBER`.

1480
Georg Brandlfee0f442010-05-22 21:26:21 +00001481- Issue #8257: The Decimal construct now accepts a float instance directly,
1482 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001483
1484 >>> Decimal(1.1)
1485 Decimal('1.100000000000000088817841970012523233890533447265625')
1486
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001487- collections.Counter() now supports a subtract() method.
1488
Georg Brandlfee0f442010-05-22 21:26:21 +00001489- The functools module now has a total_ordering() class decorator to simplify
1490 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001491
Georg Brandlfee0f442010-05-22 21:26:21 +00001492- The functools module also adds cmp_to_key() as a tool to transition old-style
1493 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001494
Georg Brandlfee0f442010-05-22 21:26:21 +00001495- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1496 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001497
Georg Brandlfee0f442010-05-22 21:26:21 +00001498- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1499 InvalidOperation instead of returning False. (Comparisons involving a quiet
1500 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1501 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001502
Georg Brandlfee0f442010-05-22 21:26:21 +00001503- Issue #2531: Comparison operations between floats and Decimal instances now
1504 return a result based on the numeric values of the operands; previously they
1505 returned an arbitrary result based on the relative ordering of id(float) and
1506 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001507
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001508- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001509 argument `-` which tells it to read files to compile from stdin. Each line is
1510 read on demand and the named file is compiled immediately. (Original patch by
1511 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001512
Georg Brandlfee0f442010-05-22 21:26:21 +00001513- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1514 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001516- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1517 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001518 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001519
Georg Brandlfee0f442010-05-22 21:26:21 +00001520- Comparisons using one of <, <=, >, >= between a complex instance and a
1521 Fractions instance now raise TypeError instead of returning True/False. This
1522 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1523 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001524

1533
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001534- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001535 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1536 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001537
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001538- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1539 deprecated.
1540
Georg Brandlfee0f442010-05-22 21:26:21 +00001541- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1542 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001543

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001578- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001579 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1580 log file to compute the next rollover time. If the log file does not exist,
1581 the current time is used as the basis for the computation.

Georg Brandlba83f822010-03-14 09:50:54 +00001591- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1592 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1593 This is a behavior change, so email's minor version number is now bumped, to
1594 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001622- Issue #8300: When passing a non-integer argument to struct.pack with any
1623 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00001627- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1628 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1629 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001630 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1631 inconsistent: __int__ was used for some integer codes but not for others, and
1632 the set of integer codes for which it was used differed between native packing
1633 and standard packing.)

2037Core and Builtins
2038-----------------
2039
Georg Brandlba83f822010-03-14 09:50:54 +00002040- The ``__complex__()`` method is now looked up on the class of instances to
2041 make it consistent with other special methods.

2045
Mark Dickinson1b34d252010-01-01 17:27:30 +00002046- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002047 DeprecationWarning when passed a float argument where an integer was expected.
2048 These functions and methods now raise TypeError instead. The majority of the
2049 effects of this change are in the extension modules, but some core functions
2050 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2051 and many unicode/str methods.

2065 of integers: the result of a/b is now correctly rounded for ints a and b (at
2066 least on IEEE 754 platforms), and in particular does not depend on the
2067 internal representation of a long.

2075
Georg Brandlba83f822010-03-14 09:50:54 +00002076 These executables now work properly with the arch(1) command: ``arch -ppc
2077 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00002234- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2235 decimal string that's guaranteed to round back to x under correct rounding
2236 (with round-half-to-even rounding mode). Previously it gave a string based on
2237 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2238 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2239 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002240
Georg Brandlba83f822010-03-14 09:50:54 +00002241- Issue #7117: On almost all platforms: float-to-string and string-to-float
2242 conversions within Python are now correctly rounded. Places these conversions
2243 occur include: str for floats and complex numbers; the float and complex
2244 constructors; old-style and new-style numeric formatting; serialization and
2245 deserialization of floats and complex numbers using marshal, pickle and json;
2246 parsing of float and imaginary literals in Python code; Decimal-to-float
2247 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002248
Georg Brandlba83f822010-03-14 09:50:54 +00002249 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2250 providing correctly-rounded strtod and dtoa C functions. This code is
2251 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2252 the C compiler. There may be a small number of platforms on which correct
2253 operation of this code cannot be guaranteed, so the code is not used: notably,
2254 this applies to platforms where the C double format is not IEEE 754 binary64,
2255 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2256 and Python's configure script is unable to determine how to change the FPU
2257 precision. On these platforms conversions use the platform strtod and dtoa,
2258 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002260- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2261 uses the correctly-rounded string <-> float conversions described above (when
2262 available), and so produces correctly rounded results that will display nicely
2263 under the float repr. There are two related small changes: (1) round now
2264 accepts any class with an ``__index__()`` method for its second argument (but
2265 no longer accepts floats for the second argument), and (2) an excessively
2266 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2267 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002409
Georg Brandlba83f822010-03-14 09:50:54 +00002410 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2411 (2) parsing of strings representing infinities and nans was locale aware; and
2412 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00002413
Georg Brandlba83f822010-03-14 09:50:54 +00002414- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2415 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2416 but with at least one decimal point and with a default precision
2417 of 12. Previously, the behavior the same but with a default precision of 6.
2418 This more closely matches ``str()``, and reduces surprises when adding
2419 alignment flags to the empty presentation type. This also affects the new
2420 complex.__format__ in the same way.
2421
2422- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2423 classtype's, even if it was None. property now inserts the __doc__ into the
2424 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002484- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002485 untrackable objects are not tracked by the garbage collector. This can reduce
2486 the size of collections and therefore the garbage collection overhead on

2494 internal representation of integers, for performance reasons. Base 2**30 is
2495 enabled by default on 64-bit machines. Add --enable-big-digits option to
2496 configure, which overrides the default. Add sys.long_info structseq to
2497 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00002598- Issue #4597: Fixed exception handling when the __exit__ function of a context
2599 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00002600
Georg Brandlba83f822010-03-14 09:50:54 +00002601- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00002602
Georg Brandlba83f822010-03-14 09:50:54 +00002603- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2604 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2605 instances. On a typical machine this saves 3 bytes of memory (on average) per
2606 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00002607
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002608- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2609 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2610 instead of throwing a MemoryError.
2611
Georg Brandlba83f822010-03-14 09:50:54 +00002612- Issue #3689: The list reversed iterator now supports __length_hint__ instead
2613 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00002614
Benjamin Petersonc078f922008-11-21 22:27:24 +00002615- Issue #4367: Python would segfault during compiling when the unicodedata
2616 module couldn't be imported and \N escapes were present.
2617
Georg Brandlba83f822010-03-14 09:50:54 +00002618- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2619 file objects with closefd=False. The file descriptor is still kept open but
2620 the file object behaves like a closed file. The ``FileIO`` object also got a
2621 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00002622
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002623- Issue #4348: Some bytearray methods returned that didn't cause any change to
2624 the bytearray, returned the same bytearray instead of a copy.
2625
Georg Brandlba83f822010-03-14 09:50:54 +00002626- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00002627
Benjamin Peterson273c2332008-11-17 22:39:09 +00002628- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
2629
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00002630- Issue #4048: The parser module now correctly validates relative imports.
2631
Benjamin Petersondcee09d2008-10-31 02:16:05 +00002632- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
2633 exec statement.
2634
Georg Brandlba83f822010-03-14 09:50:54 +00002635- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
2636 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00002637
Benjamin Petersonbdca9422008-10-26 20:21:13 +00002638- Issue #4209: Enabling unicode_literals and the print_function in the same
2639 __future__ import didn't work.
2640
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002641- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002642 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002643
Georg Brandlba83f822010-03-14 09:50:54 +00002644- On windows, ``os.chdir()`` given unicode was not working if
2645 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2646 this code path is really executed because I cannot move to such directory on
2647 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002648
Georg Brandlba83f822010-03-14 09:50:54 +00002649- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2650 element is temporarily replaced with an equivalent frozenset. But the
2651 eventual KeyError would always report the empty ``frozenset()`` as the missing
2652 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00002653
Georg Brandlba83f822010-03-14 09:50:54 +00002654- Issue #4509: Various issues surrounding resize of bytearray objects to which
2655 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00002656
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00002657- Issue #4748: Lambda generators no longer return a value.
2658
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00002659- Issue #3582: Use native TLS functions on Windows
2660
Gregory P. Smithae91d092009-03-02 05:13:57 +00002661- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
2662
Georg Brandlba83f822010-03-14 09:50:54 +00002663- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
2664 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00002665
Matthias Klose91a3b9e2009-04-05 21:19:13 +00002666- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2667 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00002668
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00002669- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
2670 returned them on 64bit platforms.
2671
Walter Dörwalded960ac2009-05-03 22:36:33 +00002672- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2673 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2674 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2675 of using the replace error handler in PyUnicode_DecodeUTF8().
2676
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002677- Issue #3739: The unicode-internal encoder now reports the number of characters
2678 consumed like any other encoder (instead of the number of bytes).
2679
Georg Brandlba83f822010-03-14 09:50:54 +00002680- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2681 allocator will be automatically disabled when running under Valgrind. This
2682 gives improved memory leak detection when running under Valgrind, while taking
2683 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00002708- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
2709 ownership when the group is not forced, because the group may be different
2710 from the user's group and inherit from its container when the test is run.

Georg Brandlba83f822010-03-14 09:50:54 +00002752- Issue #6816: runpy now provides a run_path function that allows Python code to
2753 execute file paths that refer to source or compiled Python files as well as
2754 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00002755 __main__.py file. This allows applications that run other Python scripts to
2756 support the same flexibility as the CPython command line itself.
2757
Georg Brandlba83f822010-03-14 09:50:54 +00002758- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
2759 connection with another process, rather than looping endlessly. The default
2760 timeout is 20 seconds, which should be amply sufficient for local connections.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004048- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4049
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004050- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4051 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4052 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4053 ``printf`` function, whereas PyString_FromFormat has an independent
4054 implementation and uses "%zd" on all platforms for size_t values.
4055 This makes a difference on win64, where ``printf`` needs "%Id" to display
4056 64bit values.
4057
Benjamin Peterson97179b02008-09-09 20:55:01 +00004058- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4062 object; previously an int would be returned for small values. the __long__
4063 method is allowed to return either an int or a long, but the behaviour of
4064 float objects should not change to respect backward compatibility.
4065
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004066- Issue #3751: str.rpartition would perform a left-partition when called with
4067 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004072 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004073 was correctly parsed but parsing of subsequent arguments failed.
4074
Vinay Sajip35e3b032008-09-01 14:33:59 +00004075- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004076 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4077 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4078 when given a tuple of classes as second argument, were looking up
4079 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4080 type object.
4081
Neal Norwitz18aa3882008-08-24 05:04:52 +00004082- Fix crashes on memory allocation failure found with failmalloc.
4083
4084- Fix memory leaks found with valgrind and update suppressions file.
4085
4086- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004151 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4152 for catch_warnings() also led to an improvement in the raising of a

4225-----------------
4226
Guido van Rossumf8402962008-08-20 15:01:50 +00004227- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4228 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4229 extensions do not automatically benefit from the class attribute
4230 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4231 to their tp_flags field if they care. This is a backwards
4232 compatibility feature; in 3.0, all types will use the cache by
4233 default.
4234
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004235- Keyword arguments can now follow starred arguments. (``f(a, *args,
4236 keyword=23)`` is now valid syntax.)
4237
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004238- ctypes function pointers that are COM methods have a boolean True
4239 value again.
4240
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004241- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4242 by denying s# to parse objects that have a releasebuffer procedure,
4243 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00004245- Issue #3537: Fix an assertion failure when an empty but presized dict
4246 object was stored in the freelist.
4247
Mark Dickinsonb6467572008-08-04 21:30:09 +00004248- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4249 ValueError consistently across platforms.
4250
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004251- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4252 (64bit Unix, for example), unichr() would truncate its argument and return
4253 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4254
Neal Norwitze7d8be82008-07-31 17:17:14 +00004255- Apply security patches from Apple.
4256
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004257- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00004260- Issue #1819: function calls with several named parameters are now on
4261 average 35% faster (as measured by pybench).
4262
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004263- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4264 the python debugger steps into a class statement: the free variables (local
4265 variables defined in an outer scope) would be deleted from the outer scope.
4266
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004267- Issue #2620: Overflow checking when allocating or reallocating memory
4268 was not always being done properly in some python types and extension
4269 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4270 all been updated to perform better checks and places in the code that
4271 would previously leak memory on the error path when such an allocation
4272 failed have been fixed.

4278
Benjamin Petersone977ad42008-08-20 01:42:01 +00004279- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4280 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4281
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004282- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4283 version reported by these tools does not necessarily follow the python
4284 version numbering scheme, so the module is less strict when parsing it.
4285
Nick Coghlanf70385a2008-08-18 12:42:46 +00004286- Issue #2235: Added Py3k warnings for types which will become unhashable
4287 under the stricter __hash__ inheritance rules in 3.0. Several types
4288 which did not meet the rules for hash invariants and were already
4289 unhashable in 3.0 have now been explicitly flagged as unhashable in
4290 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4291 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4292
Brett Cannon88f801d2008-08-18 00:46:22 +00004293- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4294 imported into the module but exposed as part of the module's API.
4295

4315 after a 302 response in the case of not going through a proxy.
4316
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004317- Issue #2676: in the email package, content-type parsing was hanging on
4318 pathological input because of quadratic or exponential behaviour of a
4319 regular expression.
4320
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004321- Issue #3476: binary buffered reading through the new "io" library is now
4322 thread-safe.
4323
Brett Cannonbf3157b2008-08-14 05:00:03 +00004324- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4325 since mimetools itself is deprecated. Because modules are cached, all
4326 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4327
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004328- Issue #3134: shutil referenced undefined WindowsError symbol.

4331 menu entries were not deleted.
4332
Brett Cannon83e81842008-08-09 23:30:55 +00004333- Copied the implementation of reduce() to _functools.reduce() to have a

4335
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004336- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4337 a MemoryError rather than silently stop the iteration.
4338
Guido van Rossum59ce9012008-08-09 14:55:34 +00004339- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4340 to _sre.compile() will now be rejected. This should not affect anybody
4341 since the re.compile() function never generates invalid re-bytecode.
4342
Skip Montanaroa032bf42008-08-08 22:52:51 +00004343- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4344 upon first access it can be automatically initialized from the csv file if
4345 it wasn't initialized during instantiation.
4346
Brett Cannon3aa2a492008-08-06 22:28:09 +00004347- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4348 the reload() built-in has been removed.
4349
Brett Cannon7e30b672008-08-04 21:52:25 +00004350- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004351 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4359 raised an AttributeError.
4360
Benjamin Peterson01a24322008-07-28 23:35:27 +00004361- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004362 asking for a specific length. This problem only affected files opened
4363 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004364

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004388- Issue #3394: zipfile.writestr sets external attributes when passed a
4389 file name rather than a ZipInfo instance, so files are extracted with
4390 mode 0600 rather than 000 under Unix.
4391
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004392- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4393 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004404- Issue #2235: the C API function PyObject_HashNotImplemented and its
4405 interaction with the tp_hash slot (added in 2.6b2) are now documented
4406
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004407- Issue #643841: The language reference now provides more detailed
4408 coverage of the lookup process for special methods. The disclaimers
4409 regarding lack of coverage of new-style classes have also been
4410 removed, since the coverage is now fairly reasonable.

4414================================
4415
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004416*Release date: 17-Jul-2008*
4417
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004418Core and Builtins
4419-----------------
4420
Georg Brandl3e483f62008-07-16 22:57:41 +00004421- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4422 its methods now allow for items objects that can be converted to
4423 an integer using operator.index().
4424
Mark Dickinson64b7e502008-07-16 09:40:03 +00004425- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4426 produced a ValueError instead of giving the correct float.
4427
Eric Smitha5fa5a22008-07-16 00:11:49 +00004428- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4429 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4430
Mark Dickinson7103aa42008-07-15 19:08:33 +00004431- Issue #3008: the float type has a new instance method 'float.hex'
4432 and a new class method 'float.fromhex' to convert floating-point
4433 numbers to and from hexadecimal strings, respectively.
4434
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004435- Issue #2235: __hash__ is once again inherited by default. To allow
4436 collections.Hashable to remain meaningful in the presence of the
4437 default hash implementation (object.__hash__), it is now possible
4438 to explicit block inheritance of hash by setting __hash__=None at
4439 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4440 level.
4441
Nick Coghlanb028f502008-07-13 14:52:36 +00004442- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4443 the parent module cannot be found while performing an absolute import.
4444 This means that an incorrectly defined __package__ attribute will
4445 now only prevent relative imports in that module rather than causing
4446 all imports from that module to fail.
4447
Nick Coghlan14ff9942008-07-08 14:21:42 +00004448- Issue #2517: Allow unicode messages in Exceptions again by correctly
4449 bypassing the instance dictionary when looking up __unicode__ on
4450 new-style classes.
4451
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004452- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4453 set to a custom object whose write() method happens to install
4454 another file in sys.stdout.
4455
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004456- Issue #3088: Corrected a race condition in classes derived from
4457 threading.local: the first member set by a thread could be saved in
4458 another thread's dictionary.
4459
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004460- Issue #3004: Minor change to slice.indices(): the start and stop
4461 arguments are now treated identically, making the behaviour easier
4462 to describe and understand. For example, slice(None, -10,
4463 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4464 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4465 10, -1).
4466
Georg Brandl278fc502008-07-19 12:46:12 +00004467- Issue #3219: Calling a function with repeated keyword arguments,
4468 f(a=2, a=23), would not cause a syntax error. This was a regression
4469 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004470
Georg Brandl278fc502008-07-19 12:46:12 +00004471- Issue #2862: Make int and float freelist management consistent with
4472 other freelists. Changes their CompactFreeList apis into
4473 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004474

4476-------
4477
Thomas Heller57adf222008-08-14 19:10:48 +00004478- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4479 api functions without holding the GIL, which could lead to a fatal
4480 error when they failed.
4481
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004482- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004490- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4491 ForkingPickler.register() to resolve conflict with ctypes.
4492
Vinay Sajip51e65192008-07-18 09:01:10 +00004493- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004494
Thomas Heller880f5292008-07-15 19:39:38 +00004495- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4496 a valid dlerror() message.
4497
Thomas Heller2bad6572008-07-15 17:19:50 +00004498- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4499 incomplete structure was created.
4500

4504
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004505- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004506
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004507- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4508 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004509 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004510 content-length. The problem had been corrected in the 2.4 branch, but never
4511 merged into trunk.
4512
Georg Brandle78fbcc2008-07-05 10:13:36 +00004513- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00004523- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004524 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004525
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004526- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4527 handling is now the same as that of other special attributes like __name__).
4528
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004529- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4530 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004919 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004920
4921 This is controlled by the configure argument ``--with-universal-archs``:
4922
4923 - ``--with-universal-archs=all``: install 4-way universal
4924
4925 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4926
4927 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4928
4929 This option should be used in combination with ``--enable-universalsdk=``.
4930
4931 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 +00004981- Issue #1631171: Re-implement the 'warnings' module in C (the
4982 original Python code has been kept as backup). This will allow for
4983 using the 'warning's machinery in such places as the parser where
4984 use of pure Python code is not possible. Both the ``showarning()``
4985 and ``formatwarning()`` gain an optional 'line' argument which is
4986 not called by default for backwards-compatibility reasons. Setting
4987 ``warnings.showwarning()`` to an implementation that lacks support
4988 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005051- Issue #2550: The approach used by client/server code for obtaining
5052 ports to listen on in network-oriented tests has been refined in an
5053 effort to facilitate running multiple instances of the entire
5054 regression test suite in parallel without issue.
5055 test_support.bind_port() has been fixed such that it will always
5056 return a unique port -- which wasn't always the case with the
5057 previous implementation, especially if socket options had been set
5058 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5059 new implementation of bind_port() will actually raise an exception
5060 if it is passed an AF_INET/SOCK_STREAM socket with either the
5061 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5062 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5063 the socket it's been passed. This currently only applies to
5064 Windows. This option prevents any other sockets from binding to the
5065 host/port we've bound to, thus removing the possibility of the
5066 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5067 when a second SOCK_STREAM socket binds and accepts to a host/port
5068 that's already been bound by another socket. The optional preferred
5069 port parameter to bind_port() has been removed. Under no
5070 circumstances should tests be hard coding ports!
5071
5072 test_support.find_unused_port() has also been introduced, which will
5073 pass a temporary socket object to bind_port() in order to obtain an
5074 unused port. The temporary socket object is then closed and
5075 deleted, and the port is returned. This method should only be used
5076 for obtaining an unused port in order to pass to an external program
5077 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5078 a parameter to a server-oriented class that doesn't give you direct
5079 access to the underlying socket used.
5080
5081 Finally, test_support.HOST has been introduced, which should be used
5082 for the host argument of any relevant socket calls (i.e. bind and
5083 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005084
5085 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005086 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

5088 test_asynchat and test_socket_ssl.
5089
Georg Brandl3ee81df2008-05-17 18:14:43 +00005090 It is now possible for multiple instances of the regression test

5357Core and builtins
5358-----------------
5359
Fred Drakea8ee94b2008-03-01 02:45:07 +00005360- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005361 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005362
Georg Brandlad61bc82008-02-23 15:11:18 +00005363- Issue #2067: file.__exit__() now calls subclasses' close() method.
5364
5365- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005366
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005367- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005368 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005369
Eric Smitha73fbe72008-02-23 03:09:44 +00005370- Added the future_builtins module, which contains hex() and oct().
5371 These are the PEP 3127 version of these functions, designed to be
5372 compatible with the hex() and oct() builtins from Python 3.0. They
5373 differ slightly in their output formats from the existing, unchanged
5374 Python 2.6 builtins. The expected usage of the future_builtins
5375 module is:
5376 from future_builtins import hex, oct
5377
Eric Smith7ef40bf2008-02-20 23:34:22 +00005378- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5379 exponents for exponents with absolute value < 100. Follows C99
5380 standard. This is a change on Windows, which would use 3 digits.
5381 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5382 so that any alterations it does to the resulting string will be
5383 available in stringlib/formatter.h (for float.__format__).
5384
Eric Smith5a3c1352008-02-19 13:21:56 +00005385- Implemented PEP 3101, Advanced String Formatting. This adds a new
5386 builtin format(); a format() method for str and unicode; a
5387 __format__() method to object, str, unicode, int, long, float, and
5388 datetime; the class string.Formatter; and the C API
5389 PyObject_Format().
5390
Georg Brandl3ee81df2008-05-17 18:14:43 +00005391- Fixed several potential crashes, all caused by specially crafted
5392 __del__ methods exploiting objects in temporarily inconsistent
5393 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005394
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005395- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005396 prevent a possible crash: an Abstract Base Class would try to access
5397 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005398
Georg Brandl3ee81df2008-05-17 18:14:43 +00005399- Fixed repr() and str() of complex numbers with infinity or nan as
5400 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005401
Georg Brandl3ee81df2008-05-17 18:14:43 +00005402- Clear all free lists during a gc.collect() of the highest generation
5403 in order to allow pymalloc to free more arenas. Python may give back
5404 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005405
Georg Brandl3ee81df2008-05-17 18:14:43 +00005406- Issue #2045: Fix an infinite recursion triggered when printing a
5407 subclass of collections.defaultdict, if its default_factory is set
5408 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005409
Christian Heimesf75dbef2008-02-08 00:11:31 +00005410- Fixed a minor memory leak in dictobject.c. The content of the free
5411 list was not freed on interpreter shutdown.
5412
Georg Brandl21e99f42010-03-07 15:23:59 +00005413- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005414 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005415
Georg Brandl3ee81df2008-05-17 18:14:43 +00005416- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5417 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005418 to compact the internal free lists of pre-allocted ints and floats.
5419
Georg Brandl3ee81df2008-05-17 18:14:43 +00005420- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5421 calls. Python expected the return type int but the fork familie
5422 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005423
Georg Brandl3ee81df2008-05-17 18:14:43 +00005424- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5425 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005426
Georg Brandl3ee81df2008-05-17 18:14:43 +00005427- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5428 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005429
Georg Brandl3ee81df2008-05-17 18:14:43 +00005430- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5431 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005432
Georg Brandl3ee81df2008-05-17 18:14:43 +00005433- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5434 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005435
Georg Brandl3ee81df2008-05-17 18:14:43 +00005436- Patch #1473257: generator objects gain a gi_code attribute. This is
5437 the same object as the func_code attribute of the function that
5438 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005439
Georg Brandl3ee81df2008-05-17 18:14:43 +00005440- Issue #1920: "while 0" statements were completely removed by the
5441 compiler, even in the presence of an "else" clause, which is
5442 supposed to be run when the condition is false. Now the compiler
5443 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005444
Guido van Rossumeead05f2008-01-24 18:21:02 +00005445- A few crashers fixed: weakref_in_del.py (issue #1377858);
5446 loosing_dict_ref.py (issue #1303614, test67.py);
5447 borrowed_ref_[34].py (not in tracker).
5448
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005449- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005450 suppressed while an extension is loaded by calling SetErrorMode in
5451 dynload_win.c. The error is still reported properly.
5452
Georg Brandl3ee81df2008-05-17 18:14:43 +00005453- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005454 several extension methods and modules do not work without unicode
5455 support.
5456
Georg Brandl26543b12008-01-21 18:36:51 +00005457- Issue #1882: when compiling code from a string, encoding cookies in the
5458 second line of code were not always recognized correctly.
5459
Georg Brandl14404b62008-01-19 19:27:05 +00005460- Issue #1679: "0x" was taken as a valid integer literal.
5461
Georg Brandl6caad7d2008-01-26 14:19:22 +00005462- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005463 added.
5464
Christian Heimesc94e2b52008-01-14 04:13:37 +00005465- sys.float_info / PyFloat_GetInfo: The floating point information
5466 object was converted from a dict to a specialized structseq object.
5467
Georg Brandl3ee81df2008-05-17 18:14:43 +00005468- Patch #1816: Added sys.flags structseq. It exposes the status of
5469 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005470
Georg Brandl3ee81df2008-05-17 18:14:43 +00005471- Objects/structseq.c: Implemented new structseq representation. The
5472 patch makes structseqs (e.g. the return value of os.stat) more
5473 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005474
Georg Brandl3ee81df2008-05-17 18:14:43 +00005475- Patch #1700288: added a type attribute cache that caches method
5476 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005477
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005478- Bug #1776: __import__() no longer accepts filenames on any platform.
5479 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005480
Georg Brandlaed6c662008-01-07 17:25:53 +00005481- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5482
Georg Brandl3ee81df2008-05-17 18:14:43 +00005483- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5484 envvar and sys.dont_write_bytecode attribute. All these can be set
5485 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005486
Georg Brandl3ee81df2008-05-17 18:14:43 +00005487- Improve some exception messages when Windows fails to load an
5488 extension module. Now we get for example '%1 is not a valid Win32
5489 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005490
Georg Brandl3ee81df2008-05-17 18:14:43 +00005491- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005493- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5494 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005495
Christian Heimes0a8143f2007-12-18 23:22:54 +00005496- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005497 and INF. float("nan"), float("inf") and float("-inf") now work on
5498 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005499
Georg Brandl3ee81df2008-05-17 18:14:43 +00005500- Compiler now generates simpler and faster code for dictionary
5501 literals. The oparg for BUILD_MAP now indicates an estimated
5502 dictionary size. There is a new opcode, STORE_MAP, for adding
5503 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005504
Georg Brandl3ee81df2008-05-17 18:14:43 +00005505- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005510- Issue #1538: Avoid copying string in split/rsplit if the split char
5511 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005512
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005513- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005514 SystemError.
5515
Nick Coghlanef01d822007-12-03 12:55:17 +00005516- PEP 366: Allow explicit relative imports when executing modules
5517 inside packages with the -m switch via a new module level
5518 __package__ attribute.
5519
Georg Brandl3ee81df2008-05-17 18:14:43 +00005520- Issue #1402: Fix a crash on exit, when another thread is still
5521 running, and if the deallocation of its frames somehow calls the
5522 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005523

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005527 attribute of an empty cell object.
5528
Georg Brandl3ee81df2008-05-17 18:14:43 +00005529- Issue #1460: The utf-7 incremental decoder did not accept truncated
5530 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005531
Georg Brandl3ee81df2008-05-17 18:14:43 +00005532- Patch #1739468: Directories and zipfiles containing a __main__.py
5533 file can now be directly executed by passing their name to the
5534 interpreter. The directory/zipfile is automatically inserted as the
5535 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005536
Georg Brandl3ee81df2008-05-17 18:14:43 +00005537- Issue #1265: Fix a problem with sys.settrace, if the tracing
5538 function uses a generator expression when at the same time the
5539 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005540
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005541- sets and frozensets now have an isdisjoint() method.
5542
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005543- optimize the performance of builtin.sum().
5544
Neal Norwitz44f326e2007-10-05 05:29:17 +00005545- Fix warnings found by the new version of the Coverity checker.
5546
Georg Brandl21e99f42010-03-07 15:23:59 +00005547- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005548 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5549 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005550
Georg Brandl3ee81df2008-05-17 18:14:43 +00005551- Issue #1686386: Tuple's tp_repr did not take into account the
5552 possibility of having a self-referential tuple, which is possible
5553 from C code. Nor did object's tp_str consider that a type's tp_str
5554 could do something that could lead to an inifinite recursion.
5555 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5556 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005557
Georg Brandl3ee81df2008-05-17 18:14:43 +00005558- Issue #1164: It was possible to trigger deadlock when using the
5559 'print' statement to write to a file since the GIL was not released
5560 as needed. Now PyObject_Print() does the right thing along with
5561 various tp_print implementations of the built-in types and those in
5562 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005563
Georg Brandl3ee81df2008-05-17 18:14:43 +00005564- Issue #1147: Exceptions were directly allowing string exceptions in
5565 their throw() method even though string exceptions no longer
5566 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005567
Georg Brandl3ee81df2008-05-17 18:14:43 +00005568- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00005571- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005572 PyObject_Call() never calling back out to Python code to trigger
5573 recursion depth updates/checks. Required the creation of a static
5574 RuntimeError instance in case normalizing an exception put the
5575 recursion check value past its limit. Fixes crashers
5576 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005577

Neal Norwitz0ac60192007-05-27 04:08:54 +00005591- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005592 __*__ attributes. (Some already existed, e.g., __doc__ and
5593 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005594
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005595- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00005602 "except E as target:". This is to provide forwards compatibility
5603 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005604
Brett Cannon229cee22007-05-05 01:34:02 +00005605- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005607- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005608 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005610- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005611 setting a plain string, ie don't expand to single letter identifiers.
5612
Raymond Hettinger13936692007-04-11 18:40:58 +00005613- Request #1191699: Slices can now be pickled.

5623
Guido van Rossum143b5642007-03-23 04:58:42 +00005624- Bug #1683368: The object.__init__() and object.__new__() methods are
5625 now stricter in rejecting excess arguments. The only time when
5626 either allows excess arguments is when it is not overridden and the
5627 other one is. For backwards compatibility, when both are
5628 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005629 warning later). Also, type.__init__() insists on the same signature
5630 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005631
Georg Brandl3ee81df2008-05-17 18:14:43 +00005632- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5633 object to complex using its __complex__() method before falling back
5634 to the __float__() method. Therefore, the functions in the cmath
5635 module now can operate on objects that define a __complex__()
5636 method.

5653
Georg Brandl7b9c5552007-03-12 14:30:05 +00005654- Bug #1678647: write a newline after printing an exception in any
5655 case, even when converting the value to a string failed.
5656
Georg Brandl871f1bc2007-03-12 13:17:36 +00005657- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005658 its argument, if it exists. If not, it will work like before. This
5659 allows customizing the output of dir() in the presence of a
5660 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005661
Collin Winter276887b2007-03-12 16:11:39 +00005662- Patch #922167: Python no longer segfaults when faced with infinitely
5663 self-recursive reload() calls (as reported by bug #742342).

5669 parthensized forms. This means complex(repr(x)) now works instead of
5670 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005671
Georg Brandlaa2321b2007-03-07 00:40:28 +00005672- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005673 makes the filenames the warning module prints much more sensible
5674 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005675

Georg Brandl0fca97a2007-03-05 22:28:08 +00005687- Patch #1674228: when assigning a slice (old-style), check for the
5688 sq_ass_slice instead of the sq_slice slot.
5689
Georg Brandl3ee81df2008-05-17 18:14:43 +00005690- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00006225 AttributeError instead of an IOError when the server's response
6226 didn't contain a valid HTTP status line.

6317 TestCase and TestSuite subclasses (not instances) are no longer
6318 accepted in TestSuite.addTest(). This should cause no

Georg Brandl3ee81df2008-05-17 18:14:43 +00006602- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6603 with RFC 3207 and forgets any knowledge obtained from the server not
6604 obtained from the TLS negotiation itself. Patch contributed by Bill
6605 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006606
Georg Brandl3ee81df2008-05-17 18:14:43 +00006607- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006608 that the SMTP.starttls() caller no longer needs to call ehlo()
6609 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006610 does not claim to support starttls. Adds the
6611 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6692 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6693 silently miscode subclasses of those types. Now, it raises a
6694 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006695

Georg Brandl3ee81df2008-05-17 18:14:43 +00006710 time so that opening a database previously created with the DB_DUP
6711 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6712 opens. Specifically: dictionary assignment to a DB object will
6713 replace all values for a given key when the database allows
6714 duplicate values. DB users should use DB.put(k, v) when they want
6715 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006716

6722 characters with ASCII value less than 32. Also, it correctly quotes
6723 dots only if they occur on a single line, as opposed to the previous
6724 behavior of quoting dots if they are the second character of any
6725 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007055- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7056 to ``PyTuple_SetItem``, it can be used to populate a brand new
7057 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00007059- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007061- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7062 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7063 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007064
7065- Patch #1720595: add T_BOOL to the range of structmember types.
7066
7067- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7068 ``PyFloat_GetInfo()`` to the float API.
7069
Georg Brandl3ee81df2008-05-17 18:14:43 +00007070- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7071 of w# format code incorrectly truncated the length to an int, even
7072 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7073 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007074
Georg Brandl3ee81df2008-05-17 18:14:43 +00007075- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7076 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007078- PEP 3123: Provide forward compatibility with Python 3.0, while
7079 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7080 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007081
Georg Brandl3ee81df2008-05-17 18:14:43 +00007082- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7083 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007084
7085- Patch #1733960: Allow T_LONGLONG to accept ints.
7086
7087- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7088
Christian Heimes000a0742008-01-03 22:16:32 +00007089- Added a new API function ``PyImport_ImportModuleNoBlock``.
7090
Georg Brandl6caad7d2008-01-26 14:19:22 +00007091- Bug #1637022: Prefix AST symbols with _Py_.
7092
7093- Fix some leftovers from the conversion from int to Py_ssize_t
7094 (relevant to strings and sequences of more than 2**31 items).
7095
7096- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7097 outside of pystate.c and should not be necessary.
7098
Georg Brandl3ee81df2008-05-17 18:14:43 +00007099- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7100 absolute imports. In earlier versions they might have used relative
7101 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007102
Georg Brandl3ee81df2008-05-17 18:14:43 +00007103- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7104 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007105
Georg Brandl3ee81df2008-05-17 18:14:43 +00007106- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7107 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007113- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7114 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7115 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7116 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007117
Georg Brandl3ee81df2008-05-17 18:14:43 +00007118- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00007129- buildtools now raises a DeprecationWarning.
7130
Georg Brandl3ee81df2008-05-17 18:14:43 +00007131- Removed the macfs module. It had been deprecated since Python 2.5.
7132 This lead to the deprecation of macostools.touched() as it relied
7133 solely on macfs and was a no-op under OS X.
