Ned Deily87e82bb2011-06-28 19:52:59 -070019- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
20 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
21 interpreter process. This could cause failures in non-Distutils subprocesses
22 and was unreliable since tests or user programs could modify the interpreter
23 environment after Distutils set it. Instead, have Distutils set the the
24 deployment target only in the environment of each build subprocess. It is
25 still possible to globally override the default by setting
26 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
27 greater or equal to the default value, the value with which the interpreter
28 was built.

Raymond Hettinger2c316a32011-06-25 17:14:53 +020030- Issue #11802: The cache in filecmp now has a maximum size of 100 so that

R David Murrayf1138bb2011-06-17 22:23:04 -040036- Issue #11700: mailbox proxy object close methods can now be called multiple
37 times without error, and _ProxyFile now closes the wrapped file.
38
Victor Stinnerc74a6ba2011-06-17 14:06:27 +020039- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP

Raymond Hettinger19b851d2011-06-01 18:21:42 -070056- sys.setcheckinterval() now updates the current ticker count as well as updating
57 the check interval, so if the user decreases the check interval, the ticker
58 doesn't have to wind down to zero from the old starting point before the new
59 interval takes effect. And if the user increases the interval, it makes sure
60 the new limit takes effect right away rather have an early task switch before
61 recognizing the new interval.
62
Victor Stinner776e69b2011-06-01 01:03:00 +020063- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

880 This prevents user-created self-referencing ordered dictionaries from
881 becoming permanently uncollectable GC garbage. The downside is that
882 removing __del__ means that the internal doubly-linked list has to wait for
883 GC collection rather than freeing memory immediately when the refcnt drops
884 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001343- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1344 start byte and the continuation byte(s) are now considered invalid, instead
1345 of the number of bytes specified by the start byte.
1346 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1347 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1348 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001357- Issue #8748: Fix two issues with comparisons between complex and integer
1358 objects. (1) The comparison could incorrectly return True in some cases
1359 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1360 (2) The comparison raised an OverflowError for large integers, leading
1361 to unpredictable exceptions when combining integers and complex objects
1362 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001364- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00001501- Issue #1533: Fix inconsistency in range function argument processing: any
1502 non-float non-integer argument is now converted to an integer (if possible)
1503 using its __int__ method. Previously, only small arguments were treated this
1504 way; larger arguments (those whose __int__ was outside the range of a C long)
1505 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00001513 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00001514 benefit compared to the dynamic memory allocation fallback. Patch by

1541 inheritance with the underlying socket object. The cheap inheritance has been
1542 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00001555- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1556 operation raises multiple signals and more than one of those signals is
1557 trapped, the specification determines the order in which the signals should be
1558 handled. In many cases this order wasn't being followed, leading to the wrong
1559 Python exception being raised.

1726Core and Builtins
1727-----------------
1728
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001729- Issue #7301: Add environment variable $PYTHONWARNINGS.
1730
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001731- Issue #8329: Don't return the same lists from select.select when no fds are
1732 changed.
1733
Georg Brandlfee0f442010-05-22 21:26:21 +00001734- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001735 on 64-bit machines. The shift count for either left or right shift is
1736 permitted to be up to sys.maxsize.
1737
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001738- Ensure that tokenization of identifiers is not affected by locale.
1739
Georg Brandlfee0f442010-05-22 21:26:21 +00001740- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001741
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001742- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1743
Georg Brandlfee0f442010-05-22 21:26:21 +00001744- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1745 with a non-empty format string. This is an effort to future-proof user
1746 code. If a derived class does not currently implement __format__ but later
1747 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001748 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001749 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001750
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001751- Issue #8268: Old-style classes (not just instances) now support weak
1752 references.
1753
Georg Brandlfee0f442010-05-22 21:26:21 +00001754- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
1755 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00001756
Victor Stinnerc7790ed2010-03-22 12:36:28 +00001757- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00001759- Issue #6474: Make error message from passing an inadequate number of keyword
1760 arguments to a function correct.
1761
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001762- Issue #8164: Don't allow lambda functions to have a docstring.
1763
Victor Stinner66644262010-03-10 22:30:19 +00001764- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001765 (SIGINT). If an error occurs while importing the site module, the error is
1766 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001767 module.
1768
Collin Winter001a3952010-03-18 21:54:01 +00001769- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00001774- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
1775
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001776- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001777 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
1778 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001779
Benjamin Peterson76a23c12010-04-04 23:23:22 +00001780- Issue #8310: Allow dis to examine new style classes.
1781
Georg Brandlfee0f442010-05-22 21:26:21 +00001782- Issue #8257: The Decimal construct now accepts a float instance directly,
1783 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001784
1785 >>> Decimal(1.1)
1786 Decimal('1.100000000000000088817841970012523233890533447265625')
1787
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001788- collections.Counter() now supports a subtract() method.
1789
Georg Brandlfee0f442010-05-22 21:26:21 +00001790- The functools module now has a total_ordering() class decorator to simplify
1791 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001792
Georg Brandlfee0f442010-05-22 21:26:21 +00001793- The functools module also adds cmp_to_key() as a tool to transition old-style
1794 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001795
Georg Brandlfee0f442010-05-22 21:26:21 +00001796- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1797 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001798
Georg Brandlfee0f442010-05-22 21:26:21 +00001799- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1800 InvalidOperation instead of returning False. (Comparisons involving a quiet
1801 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1802 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001803
Georg Brandlfee0f442010-05-22 21:26:21 +00001804- Issue #2531: Comparison operations between floats and Decimal instances now
1805 return a result based on the numeric values of the operands; previously they
1806 returned an arbitrary result based on the relative ordering of id(float) and
1807 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001808
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001809- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001810 argument `-` which tells it to read files to compile from stdin. Each line is
1811 read on demand and the named file is compiled immediately. (Original patch by
1812 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001813
Georg Brandlfee0f442010-05-22 21:26:21 +00001814- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1815 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001817- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1818 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001819 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001820
Georg Brandlfee0f442010-05-22 21:26:21 +00001821- Comparisons using one of <, <=, >, >= between a complex instance and a
1822 Fractions instance now raise TypeError instead of returning True/False. This
1823 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1824 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001825
Michael Foorde6410c52010-03-29 20:04:23 +00001826- Addition of ``WeakSet`` to the ``weakref`` module.

1834
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001835- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001836 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1837 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001838
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001839- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1840 deprecated.
1841
Georg Brandlfee0f442010-05-22 21:26:21 +00001842- Issue #7860: platform.uname now reports the correct 'machine' type when Python
1843 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00001844

1849 existing at the same time, causing a Unicode error when configuration code
1850 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00001851
Georg Brandlfee0f442010-05-22 21:26:21 +00001852- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
1853 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00001854
Antoine Pitroueee91cd2010-03-26 19:27:16 +00001855- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
1856 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
1857 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00001858
Florent Xiclunacf82fa62010-03-21 12:27:20 +00001859- Issue #8179: Fix macpath.realpath() on a non-existing path.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001879- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001880 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1881 log file to compute the next rollover time. If the log file does not exist,
1882 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001883

Georg Brandlba83f822010-03-14 09:50:54 +00001892- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1893 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1894 This is a behavior change, so email's minor version number is now bumped, to
1895 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001923- Issue #8300: When passing a non-integer argument to struct.pack with any
1924 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00001928- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1929 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1930 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001931 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1932 inconsistent: __int__ was used for some integer codes but not for others, and
1933 the set of integer codes for which it was used differed between native packing
1934 and standard packing.)

2340
Georg Brandlba83f822010-03-14 09:50:54 +00002341- The ``__complex__()`` method is now looked up on the class of instances to
2342 make it consistent with other special methods.

2346
Mark Dickinson1b34d252010-01-01 17:27:30 +00002347- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002348 DeprecationWarning when passed a float argument where an integer was expected.
2349 These functions and methods now raise TypeError instead. The majority of the
2350 effects of this change are in the extension modules, but some core functions
2351 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2352 and many unicode/str methods.

2366 of integers: the result of a/b is now correctly rounded for ints a and b (at
2367 least on IEEE 754 platforms), and in particular does not depend on the
2368 internal representation of a long.

2376
Georg Brandlba83f822010-03-14 09:50:54 +00002377 These executables now work properly with the arch(1) command: ``arch -ppc
2378 python`` will start a universal binary version of python in PPC mode (unlike

2519 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002520
Georg Brandlba83f822010-03-14 09:50:54 +00002521- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2522 1e50 in absolute value.

2526 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002535- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2536 decimal string that's guaranteed to round back to x under correct rounding
2537 (with round-half-to-even rounding mode). Previously it gave a string based on
2538 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2539 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2540 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002541
Georg Brandlba83f822010-03-14 09:50:54 +00002542- Issue #7117: On almost all platforms: float-to-string and string-to-float
2543 conversions within Python are now correctly rounded. Places these conversions
2544 occur include: str for floats and complex numbers; the float and complex
2545 constructors; old-style and new-style numeric formatting; serialization and
2546 deserialization of floats and complex numbers using marshal, pickle and json;
2547 parsing of float and imaginary literals in Python code; Decimal-to-float
2548 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002549
Georg Brandlba83f822010-03-14 09:50:54 +00002550 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2551 providing correctly-rounded strtod and dtoa C functions. This code is
2552 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2553 the C compiler. There may be a small number of platforms on which correct
2554 operation of this code cannot be guaranteed, so the code is not used: notably,
2555 this applies to platforms where the C double format is not IEEE 754 binary64,
2556 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2557 and Python's configure script is unable to determine how to change the FPU
2558 precision. On these platforms conversions use the platform strtod and dtoa,
2559 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002560
Georg Brandlba83f822010-03-14 09:50:54 +00002561- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2562 uses the correctly-rounded string <-> float conversions described above (when
2563 available), and so produces correctly rounded results that will display nicely
2564 under the float repr. There are two related small changes: (1) round now
2565 accepts any class with an ``__index__()`` method for its second argument (but
2566 no longer accepts floats for the second argument), and (2) an excessively
2567 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2568 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002662- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
2663 build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
2664 of stdint.h on that platform.
Mark Dickinson2f865b92009-06-30 15:32:30 +00002665

2700 literals.
Mark Dickinsona4e0efa2009-05-20 18:43:07 +00002701

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002709- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00002710
Georg Brandlba83f822010-03-14 09:50:54 +00002711 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2712 (2) parsing of strings representing infinities and nans was locale aware; and
2713 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00002714
Georg Brandlba83f822010-03-14 09:50:54 +00002715- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2716 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2717 but with at least one decimal point and with a default precision
2718 of 12. Previously, the behavior the same but with a default precision of 6.
2719 This more closely matches ``str()``, and reduces surprises when adding
2720 alignment flags to the empty presentation type. This also affects the new
2721 complex.__format__ in the same way.
2722
2723- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2724 classtype's, even if it was None. property now inserts the __doc__ into the
2725 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002785- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002786 untrackable objects are not tracked by the garbage collector. This can reduce
2787 the size of collections and therefore the garbage collection overhead on
2788 long-running programs, depending on their particular use of datatypes.

2795 internal representation of integers, for performance reasons. Base 2**30 is
2796 enabled by default on 64-bit machines. Add --enable-big-digits option to
2797 configure, which overrides the default. Add sys.long_info structseq to
2798 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00002904- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2905 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2906 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002909- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2911 instead of throwing a MemoryError.
2912
Georg Brandlba83f822010-03-14 09:50:54 +00002913- Issue #3689: The list reversed iterator now supports __length_hint__ instead

2918
Georg Brandlba83f822010-03-14 09:50:54 +00002919- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2920 file objects with closefd=False. The file descriptor is still kept open but
2921 the file object behaves like a closed file. The ``FileIO`` object also got a
2922 new readonly attribute ``closefd``.

2941
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002942- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002943 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002945- On windows, ``os.chdir()`` given unicode was not working if
2946 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2947 this code path is really executed because I cannot move to such directory on
2948 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002949
Georg Brandlba83f822010-03-14 09:50:54 +00002950- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2951 element is temporarily replaced with an equivalent frozenset. But the
2952 eventual KeyError would always report the empty ``frozenset()`` as the missing
2953 key. Now it correctly refers to the initial element.

2972
Walter Dörwalded960ac2009-05-03 22:36:33 +00002973- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2974 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2975 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2976 of using the replace error handler in PyUnicode_DecodeUTF8().
2977
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002978- Issue #3739: The unicode-internal encoder now reports the number of characters
2979 consumed like any other encoder (instead of the number of bytes).
2980
Georg Brandlba83f822010-03-14 09:50:54 +00002981- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2982 allocator will be automatically disabled when running under Valgrind. This
2983 gives improved memory leak detection when running under Valgrind, while taking
2984 advantage of pymalloc at other times.

4150 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4151 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4152 neither __int__ nor __long__, TypeError used to be raised (with a
4153 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4154 struct.error in other cases.

4157 argument with an __int__ method can be packed, but use of this feature

Georg Brandlba83f822010-03-14 09:50:54 +00004207 leak-chasing test runs give sensible results. The previous method of reaping
4208 threads could return successfully while some Thread objects were still
4209 referenced. This also introduces a new private function: ``thread._count()``.

4350
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004351- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4352 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4353 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4354 ``printf`` function, whereas PyString_FromFormat has an independent
4355 implementation and uses "%zd" on all platforms for size_t values.
4356 This makes a difference on win64, where ``printf`` needs "%Id" to display
4357 64bit values.

4363 object; previously an int would be returned for small values. the __long__
4364 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004374 was correctly parsed but parsing of subsequent arguments failed.
4375
Vinay Sajip35e3b032008-09-01 14:33:59 +00004376- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004377 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4378 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4379 when given a tuple of classes as second argument, were looking up
4380 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4381 type object.

4526-----------------
4527
Guido van Rossumf8402962008-08-20 15:01:50 +00004528- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4529 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4530 extensions do not automatically benefit from the class attribute
4531 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4532 to their tp_flags field if they care. This is a backwards
4533 compatibility feature; in 3.0, all types will use the cache by
4534 default.
4535
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004536- Keyword arguments can now follow starred arguments. (``f(a, *args,
4537 keyword=23)`` is now valid syntax.)
4538
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004539- ctypes function pointers that are COM methods have a boolean True
4540 value again.

4547 object was stored in the freelist.

4550 ValueError consistently across platforms.
4551
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004552- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4553 (64bit Unix, for example), unichr() would truncate its argument and return
4554 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00004556- Apply security patches from Apple.
4557
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004558- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4559 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4560
Antoine Pitrou92f82162008-07-25 22:22:08 +00004561- Issue #1819: function calls with several named parameters are now on
4562 average 35% faster (as measured by pybench).
4563
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004564- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4565 the python debugger steps into a class statement: the free variables (local
4566 variables defined in an outer scope) would be deleted from the outer scope.
4567
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004568- Issue #2620: Overflow checking when allocating or reallocating memory
4569 was not always being done properly in some python types and extension
4570 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4571 all been updated to perform better checks and places in the code that
4572 would previously leak memory on the error path when such an allocation
4573 failed have been fixed.

4579
Benjamin Petersone977ad42008-08-20 01:42:01 +00004580- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4581 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4582
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004583- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4584 version reported by these tools does not necessarily follow the python
4585 version numbering scheme, so the module is less strict when parsing it.
4586
Nick Coghlanf70385a2008-08-18 12:42:46 +00004587- Issue #2235: Added Py3k warnings for types which will become unhashable
4588 under the stricter __hash__ inheritance rules in 3.0. Several types
4589 which did not meet the rules for hash invariants and were already
4590 unhashable in 3.0 have now been explicitly flagged as unhashable in
4591 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4592 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4593
Brett Cannon88f801d2008-08-18 00:46:22 +00004594- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4595 imported into the module but exposed as part of the module's API.
4596

4623 thread-safe.
4624
Brett Cannonbf3157b2008-08-14 05:00:03 +00004625- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4626 since mimetools itself is deprecated. Because modules are cached, all
4627 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4628
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004629- Issue #3134: shutil referenced undefined WindowsError symbol.

4636
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004637- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4638 a MemoryError rather than silently stop the iteration.
4639
Guido van Rossum59ce9012008-08-09 14:55:34 +00004640- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4641 to _sre.compile() will now be rejected. This should not affect anybody
4642 since the re.compile() function never generates invalid re-bytecode.
4643
Skip Montanaroa032bf42008-08-08 22:52:51 +00004644- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4645 upon first access it can be automatically initialized from the csv file if
4646 it wasn't initialized during instantiation.
4647
Brett Cannon3aa2a492008-08-06 22:28:09 +00004648- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4649 the reload() built-in has been removed.
4650
Brett Cannon7e30b672008-08-04 21:52:25 +00004651- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00004663 asking for a specific length. This problem only affected files opened
4664 using the new "io" module, not the built-in open() function.

4690 file name rather than a ZipInfo instance, so files are extracted with
4691 mode 0600 rather than 000 under Unix.
4692
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004693- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4694 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004705- Issue #2235: the C API function PyObject_HashNotImplemented and its
4706 interaction with the tp_hash slot (added in 2.6b2) are now documented
4707
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004708- Issue #643841: The language reference now provides more detailed
4709 coverage of the lookup process for special methods. The disclaimers
4710 regarding lack of coverage of new-style classes have also been
4711 removed, since the coverage is now fairly reasonable.

4715================================
4716
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004717*Release date: 17-Jul-2008*
4718
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004719Core and Builtins
4720-----------------
4721
Georg Brandl3e483f62008-07-16 22:57:41 +00004722- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4723 its methods now allow for items objects that can be converted to
4724 an integer using operator.index().
4725
Mark Dickinson64b7e502008-07-16 09:40:03 +00004726- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4727 produced a ValueError instead of giving the correct float.
4728
Eric Smitha5fa5a22008-07-16 00:11:49 +00004729- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4730 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4731
Mark Dickinson7103aa42008-07-15 19:08:33 +00004732- Issue #3008: the float type has a new instance method 'float.hex'
4733 and a new class method 'float.fromhex' to convert floating-point
4734 numbers to and from hexadecimal strings, respectively.
4735
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004736- Issue #2235: __hash__ is once again inherited by default. To allow
4737 collections.Hashable to remain meaningful in the presence of the
4738 default hash implementation (object.__hash__), it is now possible
4739 to explicit block inheritance of hash by setting __hash__=None at
4740 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4741 level.
4742
Nick Coghlanb028f502008-07-13 14:52:36 +00004743- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4744 the parent module cannot be found while performing an absolute import.
4745 This means that an incorrectly defined __package__ attribute will
4746 now only prevent relative imports in that module rather than causing
4747 all imports from that module to fail.
4748
Nick Coghlan14ff9942008-07-08 14:21:42 +00004749- Issue #2517: Allow unicode messages in Exceptions again by correctly
4750 bypassing the instance dictionary when looking up __unicode__ on
4751 new-style classes.
4752
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004753- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4754 set to a custom object whose write() method happens to install
4755 another file in sys.stdout.
4756
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004757- Issue #3088: Corrected a race condition in classes derived from
4758 threading.local: the first member set by a thread could be saved in
4759 another thread's dictionary.
4760
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004761- Issue #3004: Minor change to slice.indices(): the start and stop
4762 arguments are now treated identically, making the behaviour easier
4763 to describe and understand. For example, slice(None, -10,
4764 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4765 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4766 10, -1).
4767
Georg Brandl278fc502008-07-19 12:46:12 +00004768- Issue #3219: Calling a function with repeated keyword arguments,
4769 f(a=2, a=23), would not cause a syntax error. This was a regression
4770 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004771
Georg Brandl278fc502008-07-19 12:46:12 +00004772- Issue #2862: Make int and float freelist management consistent with
4773 other freelists. Changes their CompactFreeList apis into
4774 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004775

4777-------
4778
Thomas Heller57adf222008-08-14 19:10:48 +00004779- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4780 api functions without holding the GIL, which could lead to a fatal
4781 error when they failed.
4782
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004783- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4792 ForkingPickler.register() to resolve conflict with ctypes.
4793
Vinay Sajip51e65192008-07-18 09:01:10 +00004794- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00004796- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4797 a valid dlerror() message.
4798
Thomas Heller2bad6572008-07-15 17:19:50 +00004799- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4800 incomplete structure was created.
4801

4805
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004806- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004807
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004808- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4809 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004810 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004811 content-length. The problem had been corrected in the 2.4 branch, but never
4812 merged into trunk.
4813
Georg Brandle78fbcc2008-07-05 10:13:36 +00004814- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00004824- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004825 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004826
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004827- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4828 handling is now the same as that of other special attributes like __name__).
4829
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004830- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4831 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00005220 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005221
5222 This is controlled by the configure argument ``--with-universal-archs``:
5223
5224 - ``--with-universal-archs=all``: install 4-way universal
5225
5226 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5227
5228 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5229
5230 This option should be used in combination with ``--enable-universalsdk=``.
5231
5232 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 +00005282- Issue #1631171: Re-implement the 'warnings' module in C (the
5283 original Python code has been kept as backup). This will allow for
5284 using the 'warning's machinery in such places as the parser where
5285 use of pure Python code is not possible. Both the ``showarning()``
5286 and ``formatwarning()`` gain an optional 'line' argument which is
5287 not called by default for backwards-compatibility reasons. Setting
5288 ``warnings.showwarning()`` to an implementation that lacks support
5289 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005352- Issue #2550: The approach used by client/server code for obtaining
5353 ports to listen on in network-oriented tests has been refined in an
5354 effort to facilitate running multiple instances of the entire
5355 regression test suite in parallel without issue.
5356 test_support.bind_port() has been fixed such that it will always
5357 return a unique port -- which wasn't always the case with the
5358 previous implementation, especially if socket options had been set
5359 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5360 new implementation of bind_port() will actually raise an exception
5361 if it is passed an AF_INET/SOCK_STREAM socket with either the
5362 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5363 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5364 the socket it's been passed. This currently only applies to
5365 Windows. This option prevents any other sockets from binding to the
5366 host/port we've bound to, thus removing the possibility of the
5367 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5368 when a second SOCK_STREAM socket binds and accepts to a host/port
5369 that's already been bound by another socket. The optional preferred
5370 port parameter to bind_port() has been removed. Under no
5371 circumstances should tests be hard coding ports!
5372
5373 test_support.find_unused_port() has also been introduced, which will
5374 pass a temporary socket object to bind_port() in order to obtain an
5375 unused port. The temporary socket object is then closed and
5376 deleted, and the port is returned. This method should only be used
5377 for obtaining an unused port in order to pass to an external program
5378 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5379 a parameter to a server-oriented class that doesn't give you direct
5380 access to the underlying socket used.
5381
5382 Finally, test_support.HOST has been introduced, which should be used
5383 for the host argument of any relevant socket calls (i.e. bind and
5384 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005385
5386 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005387 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005388 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5389 test_asynchat and test_socket_ssl.
5390
Georg Brandl3ee81df2008-05-17 18:14:43 +00005391 It is now possible for multiple instances of the regression test
5392 suite to run in parallel without issue.

5659-----------------
5660
Fred Drakea8ee94b2008-03-01 02:45:07 +00005661- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005662 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005663
Georg Brandlad61bc82008-02-23 15:11:18 +00005664- Issue #2067: file.__exit__() now calls subclasses' close() method.
5665
5666- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005667
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005668- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005669 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005670
Eric Smitha73fbe72008-02-23 03:09:44 +00005671- Added the future_builtins module, which contains hex() and oct().
5672 These are the PEP 3127 version of these functions, designed to be
5673 compatible with the hex() and oct() builtins from Python 3.0. They
5674 differ slightly in their output formats from the existing, unchanged
5675 Python 2.6 builtins. The expected usage of the future_builtins
5676 module is:
5677 from future_builtins import hex, oct
5678
Eric Smith7ef40bf2008-02-20 23:34:22 +00005679- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5680 exponents for exponents with absolute value < 100. Follows C99
5681 standard. This is a change on Windows, which would use 3 digits.
5682 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5683 so that any alterations it does to the resulting string will be
5684 available in stringlib/formatter.h (for float.__format__).
5685
Eric Smith5a3c1352008-02-19 13:21:56 +00005686- Implemented PEP 3101, Advanced String Formatting. This adds a new
5687 builtin format(); a format() method for str and unicode; a
5688 __format__() method to object, str, unicode, int, long, float, and
5689 datetime; the class string.Formatter; and the C API
5690 PyObject_Format().
5691
Georg Brandl3ee81df2008-05-17 18:14:43 +00005692- Fixed several potential crashes, all caused by specially crafted
5693 __del__ methods exploiting objects in temporarily inconsistent
5694 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005695
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005696- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005697 prevent a possible crash: an Abstract Base Class would try to access
5698 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005699
Georg Brandl3ee81df2008-05-17 18:14:43 +00005700- Fixed repr() and str() of complex numbers with infinity or nan as
5701 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005702
Georg Brandl3ee81df2008-05-17 18:14:43 +00005703- Clear all free lists during a gc.collect() of the highest generation
5704 in order to allow pymalloc to free more arenas. Python may give back
5705 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005706
Georg Brandl3ee81df2008-05-17 18:14:43 +00005707- Issue #2045: Fix an infinite recursion triggered when printing a
5708 subclass of collections.defaultdict, if its default_factory is set
5709 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005710
Christian Heimesf75dbef2008-02-08 00:11:31 +00005711- Fixed a minor memory leak in dictobject.c. The content of the free
5712 list was not freed on interpreter shutdown.
5713
Georg Brandl21e99f42010-03-07 15:23:59 +00005714- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005715 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005716
Georg Brandl3ee81df2008-05-17 18:14:43 +00005717- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5718 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005719 to compact the internal free lists of pre-allocted ints and floats.
5720
Georg Brandl3ee81df2008-05-17 18:14:43 +00005721- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5722 calls. Python expected the return type int but the fork familie
5723 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005724
Georg Brandl3ee81df2008-05-17 18:14:43 +00005725- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5726 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005727
Georg Brandl3ee81df2008-05-17 18:14:43 +00005728- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5729 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005730
Georg Brandl3ee81df2008-05-17 18:14:43 +00005731- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5732 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005733
Georg Brandl3ee81df2008-05-17 18:14:43 +00005734- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5735 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005736
Georg Brandl3ee81df2008-05-17 18:14:43 +00005737- Patch #1473257: generator objects gain a gi_code attribute. This is
5738 the same object as the func_code attribute of the function that
5739 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005740
Georg Brandl3ee81df2008-05-17 18:14:43 +00005741- Issue #1920: "while 0" statements were completely removed by the
5742 compiler, even in the presence of an "else" clause, which is
5743 supposed to be run when the condition is false. Now the compiler
5744 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005745
Guido van Rossumeead05f2008-01-24 18:21:02 +00005746- A few crashers fixed: weakref_in_del.py (issue #1377858);
5747 loosing_dict_ref.py (issue #1303614, test67.py);
5748 borrowed_ref_[34].py (not in tracker).
5749
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005750- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005751 suppressed while an extension is loaded by calling SetErrorMode in
5752 dynload_win.c. The error is still reported properly.
5753
Georg Brandl3ee81df2008-05-17 18:14:43 +00005754- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005755 several extension methods and modules do not work without unicode
5756 support.
5757
Georg Brandl26543b12008-01-21 18:36:51 +00005758- Issue #1882: when compiling code from a string, encoding cookies in the
5759 second line of code were not always recognized correctly.
5760
Georg Brandl14404b62008-01-19 19:27:05 +00005761- Issue #1679: "0x" was taken as a valid integer literal.
5762
Georg Brandl6caad7d2008-01-26 14:19:22 +00005763- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005764 added.
5765
Christian Heimesc94e2b52008-01-14 04:13:37 +00005766- sys.float_info / PyFloat_GetInfo: The floating point information
5767 object was converted from a dict to a specialized structseq object.
5768
Georg Brandl3ee81df2008-05-17 18:14:43 +00005769- Patch #1816: Added sys.flags structseq. It exposes the status of
5770 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005771
Georg Brandl3ee81df2008-05-17 18:14:43 +00005772- Objects/structseq.c: Implemented new structseq representation. The
5773 patch makes structseqs (e.g. the return value of os.stat) more
5774 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005775
Georg Brandl3ee81df2008-05-17 18:14:43 +00005776- Patch #1700288: added a type attribute cache that caches method
5777 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005778
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005779- Bug #1776: __import__() no longer accepts filenames on any platform.
5780 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005781
Georg Brandlaed6c662008-01-07 17:25:53 +00005782- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5783
Georg Brandl3ee81df2008-05-17 18:14:43 +00005784- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5785 envvar and sys.dont_write_bytecode attribute. All these can be set
5786 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005787
Georg Brandl3ee81df2008-05-17 18:14:43 +00005788- Improve some exception messages when Windows fails to load an
5789 extension module. Now we get for example '%1 is not a valid Win32
5790 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005791
Georg Brandl3ee81df2008-05-17 18:14:43 +00005792- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005794- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5795 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005796
Christian Heimes0a8143f2007-12-18 23:22:54 +00005797- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005798 and INF. float("nan"), float("inf") and float("-inf") now work on
5799 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005800
Georg Brandl3ee81df2008-05-17 18:14:43 +00005801- Compiler now generates simpler and faster code for dictionary
5802 literals. The oparg for BUILD_MAP now indicates an estimated
5803 dictionary size. There is a new opcode, STORE_MAP, for adding
5804 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005805
Georg Brandl3ee81df2008-05-17 18:14:43 +00005806- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005811- Issue #1538: Avoid copying string in split/rsplit if the split char
5812 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005813
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005814- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005815 SystemError.
5816
Nick Coghlanef01d822007-12-03 12:55:17 +00005817- PEP 366: Allow explicit relative imports when executing modules

5819 __package__ attribute.
5820
Georg Brandl3ee81df2008-05-17 18:14:43 +00005821- Issue #1402: Fix a crash on exit, when another thread is still
5822 running, and if the deallocation of its frames somehow calls the
5823 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005824

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005828 attribute of an empty cell object.
5829
Georg Brandl3ee81df2008-05-17 18:14:43 +00005830- Issue #1460: The utf-7 incremental decoder did not accept truncated
5831 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005832
Georg Brandl3ee81df2008-05-17 18:14:43 +00005833- Patch #1739468: Directories and zipfiles containing a __main__.py
5834 file can now be directly executed by passing their name to the
5835 interpreter. The directory/zipfile is automatically inserted as the
5836 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005837
Georg Brandl3ee81df2008-05-17 18:14:43 +00005838- Issue #1265: Fix a problem with sys.settrace, if the tracing
5839 function uses a generator expression when at the same time the
5840 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005841
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005842- sets and frozensets now have an isdisjoint() method.
5843
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005844- optimize the performance of builtin.sum().
5845
Neal Norwitz44f326e2007-10-05 05:29:17 +00005846- Fix warnings found by the new version of the Coverity checker.
5847
Georg Brandl21e99f42010-03-07 15:23:59 +00005848- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005849 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5850 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005851
Georg Brandl3ee81df2008-05-17 18:14:43 +00005852- Issue #1686386: Tuple's tp_repr did not take into account the
5853 possibility of having a self-referential tuple, which is possible
5854 from C code. Nor did object's tp_str consider that a type's tp_str
5855 could do something that could lead to an inifinite recursion.
5856 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5857 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005858
Georg Brandl3ee81df2008-05-17 18:14:43 +00005859- Issue #1164: It was possible to trigger deadlock when using the
5860 'print' statement to write to a file since the GIL was not released
5861 as needed. Now PyObject_Print() does the right thing along with
5862 various tp_print implementations of the built-in types and those in
5863 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005864
Georg Brandl3ee81df2008-05-17 18:14:43 +00005865- Issue #1147: Exceptions were directly allowing string exceptions in
5866 their throw() method even though string exceptions no longer
5867 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005868

Brett Cannon1e534b52007-09-07 04:18:30 +00005872- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005873 PyObject_Call() never calling back out to Python code to trigger
5874 recursion depth updates/checks. Required the creation of a static
5875 RuntimeError instance in case normalizing an exception put the
5876 recursion check value past its limit. Fixes crashers
5877 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005878
Georg Brandl3ee81df2008-05-17 18:14:43 +00005879- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005892- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005893 __*__ attributes. (Some already existed, e.g., __doc__ and
5894 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005895
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005896- Add -3 option to the interpreter to warn about features that are

5901
Collin Winter62903052007-05-18 23:11:24 +00005902- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005903 "except E as target:". This is to provide forwards compatibility
5904 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005905
Brett Cannon229cee22007-05-05 01:34:02 +00005906- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005908- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005909 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005911- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005912 setting a plain string, ie don't expand to single letter identifiers.
5913
Raymond Hettinger13936692007-04-11 18:40:58 +00005914- Request #1191699: Slices can now be pickled.

5924
Guido van Rossum143b5642007-03-23 04:58:42 +00005925- Bug #1683368: The object.__init__() and object.__new__() methods are
5926 now stricter in rejecting excess arguments. The only time when
5927 either allows excess arguments is when it is not overridden and the
5928 other one is. For backwards compatibility, when both are
5929 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005930 warning later). Also, type.__init__() insists on the same signature
5931 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005932
Georg Brandl3ee81df2008-05-17 18:14:43 +00005933- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5934 object to complex using its __complex__() method before falling back
5935 to the __float__() method. Therefore, the functions in the cmath
5936 module now can operate on objects that define a __complex__()
5937 method.

5954
Georg Brandl7b9c5552007-03-12 14:30:05 +00005955- Bug #1678647: write a newline after printing an exception in any
5956 case, even when converting the value to a string failed.
5957
Georg Brandl871f1bc2007-03-12 13:17:36 +00005958- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005959 its argument, if it exists. If not, it will work like before. This
5960 allows customizing the output of dir() in the presence of a
5961 __getattr__().

5970 parthensized forms. This means complex(repr(x)) now works instead of
5971 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005972
Georg Brandlaa2321b2007-03-07 00:40:28 +00005973- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005974 makes the filenames the warning module prints much more sensible
5975 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005976

Georg Brandl0fca97a2007-03-05 22:28:08 +00005988- Patch #1674228: when assigning a slice (old-style), check for the
5989 sq_ass_slice instead of the sq_slice slot.
5990
Georg Brandl3ee81df2008-05-17 18:14:43 +00005991- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00006526 AttributeError instead of an IOError when the server's response

Georg Brandl3ee81df2008-05-17 18:14:43 +00006903- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6904 with RFC 3207 and forgets any knowledge obtained from the server not
6905 obtained from the TLS negotiation itself. Patch contributed by Bill
6906 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006907
Georg Brandl3ee81df2008-05-17 18:14:43 +00006908- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006909 that the SMTP.starttls() caller no longer needs to call ehlo()
6910 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006911 does not claim to support starttls. Adds the
6912 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00007011 time so that opening a database previously created with the DB_DUP
7012 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7013 opens. Specifically: dictionary assignment to a DB object will
7014 replace all values for a given key when the database allows
7015 duplicate values. DB users should use DB.put(k, v) when they want
7016 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007017

7023 characters with ASCII value less than 32. Also, it correctly quotes
7024 dots only if they occur on a single line, as opposed to the previous
7025 behavior of quoting dots if they are the second character of any
7026 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007356- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7357 to ``PyTuple_SetItem``, it can be used to populate a brand new
7358 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00007360- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007362- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7363 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7364 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007365
7366- Patch #1720595: add T_BOOL to the range of structmember types.
7367
7368- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7369 ``PyFloat_GetInfo()`` to the float API.
7370
Georg Brandl3ee81df2008-05-17 18:14:43 +00007371- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7372 of w# format code incorrectly truncated the length to an int, even
7373 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7374 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007375
Georg Brandl3ee81df2008-05-17 18:14:43 +00007376- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7377 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007378
Georg Brandl3ee81df2008-05-17 18:14:43 +00007379- PEP 3123: Provide forward compatibility with Python 3.0, while
7380 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7381 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007382
Georg Brandl3ee81df2008-05-17 18:14:43 +00007383- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7384 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007385
7386- Patch #1733960: Allow T_LONGLONG to accept ints.
7387
7388- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7389
Christian Heimes000a0742008-01-03 22:16:32 +00007390- Added a new API function ``PyImport_ImportModuleNoBlock``.
7391
Georg Brandl6caad7d2008-01-26 14:19:22 +00007392- Bug #1637022: Prefix AST symbols with _Py_.
7393
7394- Fix some leftovers from the conversion from int to Py_ssize_t
7395 (relevant to strings and sequences of more than 2**31 items).
7396
7397- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7398 outside of pystate.c and should not be necessary.
7399
Georg Brandl3ee81df2008-05-17 18:14:43 +00007400- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7401 absolute imports. In earlier versions they might have used relative
7402 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007403
Georg Brandl3ee81df2008-05-17 18:14:43 +00007404- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7405 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007406
Georg Brandl3ee81df2008-05-17 18:14:43 +00007407- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7408 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007414- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7415 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7416 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7417 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007418
Georg Brandl3ee81df2008-05-17 18:14:43 +00007419- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
7420 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00007430- buildtools now raises a DeprecationWarning.
7431
Georg Brandl3ee81df2008-05-17 18:14:43 +00007432- Removed the macfs module. It had been deprecated since Python 2.5.
7433 This lead to the deprecation of macostools.touched() as it relied
7434 solely on macfs and was a no-op under OS X.
