13 Python 3.1. callable() is again supported in Python 3.2.
14
Victor Stinner59729ff2011-07-05 11:28:19 +020015- Issue #9611, #9015: FileIO.read(), FileIO.readinto(), FileIO.write() and
16 os.write() clamp the length to INT_MAX on Windows.
17
Victor Stinnerd3c7e172011-05-30 23:49:13 +020018- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +020019 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
20 raw_input() interrupted by CTRL+c.

34 the garbage collector while the Heap lock is held.
35
Ned Deily87e82bb2011-06-28 19:52:59 -070036- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
37 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
38 interpreter process. This could cause failures in non-Distutils subprocesses
39 and was unreliable since tests or user programs could modify the interpreter
40 environment after Distutils set it. Instead, have Distutils set the the
41 deployment target only in the environment of each build subprocess. It is
42 still possible to globally override the default by setting
43 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
44 greater or equal to the default value, the value with which the interpreter
45 was built.
46
Raymond Hettinger2c316a32011-06-25 17:14:53 +020047- Issue #11802: The cache in filecmp now has a maximum size of 100 so that

54 times without error, and _ProxyFile now closes the wrapped file.
55
Victor Stinnerc74a6ba2011-06-17 14:06:27 +020056- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
57 connection if its getresponse() method fails with a socket error. Patch
58 written by Ezio Melotti.
59
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -050060- Issue #9284: Allow inspect.findsource() to find the source of doctest

72
Raymond Hettinger19b851d2011-06-01 18:21:42 -070073- sys.setcheckinterval() now updates the current ticker count as well as updating
74 the check interval, so if the user decreases the check interval, the ticker
75 doesn't have to wind down to zero from the old starting point before the new
76 interval takes effect. And if the user increases the interval, it makes sure
77 the new limit takes effect right away rather have an early task switch before
78 recognizing the new interval.
79
Victor Stinner776e69b2011-06-01 01:03:00 +020080- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the
81 constructor has failed, e.g. because of an undeclared keyword argument. Patch

102
Ned Deily63144c62011-06-28 00:39:19 -0700103- Issue #12141: Install a copy of template C module file so that

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

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001368- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1369 start byte and the continuation byte(s) are now considered invalid, instead
1370 of the number of bytes specified by the start byte.
1371 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1372 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1373 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

1383 objects. (1) The comparison could incorrectly return True in some cases
1384 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1385 (2) The comparison raised an OverflowError for large integers, leading

1527 non-float non-integer argument is now converted to an integer (if possible)
1528 using its __int__ method. Previously, only small arguments were treated this
1529 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00001580- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1581 operation raises multiple signals and more than one of those signals is
1582 trapped, the specification determines the order in which the signals should be
1583 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00001728- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001729 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1730 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1731 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1751Core and Builtins
1752-----------------
1753
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001754- Issue #7301: Add environment variable $PYTHONWARNINGS.
1755
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001756- Issue #8329: Don't return the same lists from select.select when no fds are
1757 changed.
1758
Georg Brandlfee0f442010-05-22 21:26:21 +00001759- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001760 on 64-bit machines. The shift count for either left or right shift is
1761 permitted to be up to sys.maxsize.
1762
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001763- Ensure that tokenization of identifiers is not affected by locale.
1764
Georg Brandlfee0f442010-05-22 21:26:21 +00001765- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001766
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001767- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1768
Georg Brandlfee0f442010-05-22 21:26:21 +00001769- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1770 with a non-empty format string. This is an effort to future-proof user
1771 code. If a derived class does not currently implement __format__ but later
1772 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001773 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001774 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001775
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001776- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00001789- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001790 (SIGINT). If an error occurs while importing the site module, the error is
1791 printed and Python exits. Initialize the GIL before importing the site

1806
Georg Brandlfee0f442010-05-22 21:26:21 +00001807- Issue #8257: The Decimal construct now accepts a float instance directly,
1808 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001809
1810 >>> Decimal(1.1)
1811 Decimal('1.100000000000000088817841970012523233890533447265625')
1812
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001813- collections.Counter() now supports a subtract() method.
1814
Georg Brandlfee0f442010-05-22 21:26:21 +00001815- The functools module now has a total_ordering() class decorator to simplify
1816 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001817
Georg Brandlfee0f442010-05-22 21:26:21 +00001818- The functools module also adds cmp_to_key() as a tool to transition old-style
1819 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001820
Georg Brandlfee0f442010-05-22 21:26:21 +00001821- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1822 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001823
Georg Brandlfee0f442010-05-22 21:26:21 +00001824- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1825 InvalidOperation instead of returning False. (Comparisons involving a quiet
1826 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1827 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001828
Georg Brandlfee0f442010-05-22 21:26:21 +00001829- Issue #2531: Comparison operations between floats and Decimal instances now
1830 return a result based on the numeric values of the operands; previously they
1831 returned an arbitrary result based on the relative ordering of id(float) and
1832 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001833
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001834- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001835 argument `-` which tells it to read files to compile from stdin. Each line is
1836 read on demand and the named file is compiled immediately. (Original patch by
1837 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001838
Georg Brandlfee0f442010-05-22 21:26:21 +00001839- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001842- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1843 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001844 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001845
Georg Brandlfee0f442010-05-22 21:26:21 +00001846- Comparisons using one of <, <=, >, >= between a complex instance and a
1847 Fractions instance now raise TypeError instead of returning True/False. This
1848 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1849 <=> complex, and complex <=> complex comparisons.

Antoine Pitroubb445a12010-02-05 17:05:54 +00002190- Issue #5677: Explicitly forbid write operations on read-only file objects,
2191 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002192 library would return a bogus result; on Solaris, it was possible to crash the
2193 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00002206- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2207 and add the additional members returned in an OSVERSIONINFOEX structure. The
2208 new members are service_pack_major, service_pack_minor, suite_mask, and
2209 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00002211- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2212 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2213 returning NULL. The macro now returns a statically allocated empty string
2214 instead.

2224 strings,
2225 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2226 numeric strings corresponding to subnormal values,
2227 (3) a memory leak for some values large enough to cause overflow, and
2228 (4) a number of flaws that could lead to incorrectly rounded results.
2229

2246 interpreter shutdown.
2247
Georg Brandlba83f822010-03-14 09:50:54 +00002248- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
2249 XML processing instructions and comments. These raw characters are allowed
2250 by the XML specification, and are necessary when outputting e.g. PHP code in
2251 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00002259- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002260 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002261 Also, raise ValueError rather than TypeError when an unknown TIPC address
2262 type is specified. Patch by Brian Curtin.
2263
Vinay Sajip28c382f2010-02-04 18:48:53 +00002264- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002266- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002267 file position when calling `truncate()`. It would previously change the file
2268 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002269 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2270
Georg Brandlba83f822010-03-14 09:50:54 +00002271- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2272 class used to represent files stored inside an archive. The new
2273 implementation is significantly faster and can be wrapped in a
2274 ``io.BufferedReader`` object for more speedups. It also solves an issue
2275 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2276 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00002285
Georg Brandlba83f822010-03-14 09:50:54 +00002286- Issue #7748: Since unicode values are supported for some metadata options in
2287 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2288 encoded string for them. This ensures that the upload and register commands
2289 send the correct values to PyPI without any error.

2365
Georg Brandlba83f822010-03-14 09:50:54 +00002366- The ``__complex__()`` method is now looked up on the class of instances to
2367 make it consistent with other special methods.

2371
Mark Dickinson1b34d252010-01-01 17:27:30 +00002372- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002373 DeprecationWarning when passed a float argument where an integer was expected.
2374 These functions and methods now raise TypeError instead. The majority of the
2375 effects of this change are in the extension modules, but some core functions
2376 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2377 and many unicode/str methods.

2401
Georg Brandlba83f822010-03-14 09:50:54 +00002402 These executables now work properly with the arch(1) command: ``arch -ppc
2403 python`` will start a universal binary version of python in PPC mode (unlike
2404 previous releases).

2544 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002545
Georg Brandlba83f822010-03-14 09:50:54 +00002546- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2547 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002548

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002559
Georg Brandlba83f822010-03-14 09:50:54 +00002560- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2561 decimal string that's guaranteed to round back to x under correct rounding
2562 (with round-half-to-even rounding mode). Previously it gave a string based on
2563 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2564 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2565 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002566
Georg Brandlba83f822010-03-14 09:50:54 +00002567- Issue #7117: On almost all platforms: float-to-string and string-to-float
2568 conversions within Python are now correctly rounded. Places these conversions
2569 occur include: str for floats and complex numbers; the float and complex
2570 constructors; old-style and new-style numeric formatting; serialization and
2571 deserialization of floats and complex numbers using marshal, pickle and json;
2572 parsing of float and imaginary literals in Python code; Decimal-to-float
2573 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002574
Georg Brandlba83f822010-03-14 09:50:54 +00002575 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2576 providing correctly-rounded strtod and dtoa C functions. This code is
2577 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2578 the C compiler. There may be a small number of platforms on which correct
2579 operation of this code cannot be guaranteed, so the code is not used: notably,
2580 this applies to platforms where the C double format is not IEEE 754 binary64,
2581 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2582 and Python's configure script is unable to determine how to change the FPU
2583 precision. On these platforms conversions use the platform strtod and dtoa,
2584 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002585
Georg Brandlba83f822010-03-14 09:50:54 +00002586- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2587 uses the correctly-rounded string <-> float conversions described above (when
2588 available), and so produces correctly rounded results that will display nicely
2589 under the float repr. There are two related small changes: (1) round now
2590 accepts any class with an ``__index__()`` method for its second argument (but
2591 no longer accepts floats for the second argument), and (2) an excessively
2592 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2593 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002740- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2741 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2742 but with at least one decimal point and with a default precision
2743 of 12. Previously, the behavior the same but with a default precision of 6.
2744 This more closely matches ``str()``, and reduces surprises when adding
2745 alignment flags to the empty presentation type. This also affects the new
2746 complex.__format__ in the same way.

Benjamin Peterson7af65562008-12-29 17:56:58 +00002903- Issue #4764: With io.open, IOError.filename is set when trying to open a

2905
Benjamin Petersonfe231b02008-12-29 17:47:42 +00002906- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
2907 systems.
2908
Georg Brandl6425a2f2008-12-28 11:54:53 +00002909- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002910 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002911
Skip Montanarof205c132008-12-23 03:30:15 +00002912- Added test case to ensure attempts to read from a file opened for writing
2913 fail.
2914
Georg Brandlba83f822010-03-14 09:50:54 +00002915- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
2916 elapsed times, not only when some objects are uncollectable/unreachable.
2917 Original patch by Neil Schemenauer.

Georg Brandlba83f822010-03-14 09:50:54 +00002929- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2930 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2931 instances. On a typical machine this saves 3 bytes of memory (on average) per
2932 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00002933
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002934- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2935 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2936 instead of throwing a MemoryError.
2937
Georg Brandlba83f822010-03-14 09:50:54 +00002938- Issue #3689: The list reversed iterator now supports __length_hint__ instead
2939 of __len__. Behavior now matches other reversed iterators.

Benjamin Petersonc078f922008-11-21 22:27:24 +00002941- Issue #4367: Python would segfault during compiling when the unicodedata
2942 module couldn't be imported and \N escapes were present.
2943
Georg Brandlba83f822010-03-14 09:50:54 +00002944- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2945 file objects with closefd=False. The file descriptor is still kept open but
2946 the file object behaves like a closed file. The ``FileIO`` object also got a
2947 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00002948
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002949- Issue #4348: Some bytearray methods returned that didn't cause any change to
2950 the bytearray, returned the same bytearray instead of a copy.
2951
Georg Brandlba83f822010-03-14 09:50:54 +00002952- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson6624a9f2008-11-03 15:14:51 +00002956- Issue #4048: The parser module now correctly validates relative imports.
2957
Benjamin Petersondcee09d2008-10-31 02:16:05 +00002958- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

2960
Georg Brandlba83f822010-03-14 09:50:54 +00002961- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method

Benjamin Petersonbdca9422008-10-26 20:21:13 +00002964- Issue #4209: Enabling unicode_literals and the print_function in the same
2965 __future__ import didn't work.
2966
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002967- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002968 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002969
Georg Brandlba83f822010-03-14 09:50:54 +00002970- On windows, ``os.chdir()`` given unicode was not working if
2971 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2972 this code path is really executed because I cannot move to such directory on
2973 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002974
Georg Brandlba83f822010-03-14 09:50:54 +00002975- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2976 element is temporarily replaced with an equivalent frozenset. But the
2977 eventual KeyError would always report the empty ``frozenset()`` as the missing
2978 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00002979
Georg Brandlba83f822010-03-14 09:50:54 +00002980- Issue #4509: Various issues surrounding resize of bytearray objects to which

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00002995- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
2996 returned them on 64bit platforms.
2997
Walter Dörwalded960ac2009-05-03 22:36:33 +00002998- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2999 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3000 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3001 of using the replace error handler in PyUnicode_DecodeUTF8().
3002
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003003- Issue #3739: The unicode-internal encoder now reports the number of characters
3004 consumed like any other encoder (instead of the number of bytes).
3005
Georg Brandlba83f822010-03-14 09:50:54 +00003006- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3007 allocator will be automatically disabled when running under Valgrind. This
3008 gives improved memory leak detection when running under Valgrind, while taking
3009 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004253 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4254 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00004256- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
4257 regression tests in parallel, shortening the total runtime.
4258
Georg Brandlba83f822010-03-14 09:50:54 +00004259- Issue #5354: New test support function import_fresh_module() makes it easy to
4260 import both normal and optimised versions of modules. test_heapq and
4261 test_warnings have been adjusted to use it, tests for other modules with both
4262 C and Python implementations in the stdlib can be adjusted to use it over
4263 time.

4272 should cause a test to be skipped are now done using import_module from test
4273 support, which does the conversion.

4375
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004376- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4377 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4378 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4379 ``printf`` function, whereas PyString_FromFormat has an independent
4380 implementation and uses "%zd" on all platforms for size_t values.
4381 This makes a difference on win64, where ``printf`` needs "%Id" to display
4382 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004384- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4388 object; previously an int would be returned for small values. the __long__
4389 method is allowed to return either an int or a long, but the behaviour of

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004392- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004399 was correctly parsed but parsing of subsequent arguments failed.
4400
Vinay Sajip35e3b032008-09-01 14:33:59 +00004401- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004402 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4403 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4404 when given a tuple of classes as second argument, were looking up
4405 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4406 type object.
4407
Neal Norwitz18aa3882008-08-24 05:04:52 +00004408- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004545What's New in Python 2.6 beta 3?
4546================================
4547
Barry Warsaw07a4a382008-08-21 01:15:08 +00004548*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004549
4550Core and Builtins
4551-----------------
4552
Guido van Rossumf8402962008-08-20 15:01:50 +00004553- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4554 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4555 extensions do not automatically benefit from the class attribute
4556 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4557 to their tp_flags field if they care. This is a backwards
4558 compatibility feature; in 3.0, all types will use the cache by
4559 default.
4560
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004561- Keyword arguments can now follow starred arguments. (``f(a, *args,
4562 keyword=23)`` is now valid syntax.)
4563
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004564- ctypes function pointers that are COM methods have a boolean True
4565 value again.
4566
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004567- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4568 by denying s# to parse objects that have a releasebuffer procedure,
4569 and introducing s*.
4570
Georg Brandl1e13ea92008-08-11 09:07:59 +00004571- Issue #3537: Fix an assertion failure when an empty but presized dict
4572 object was stored in the freelist.
4573
Mark Dickinsonb6467572008-08-04 21:30:09 +00004574- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4575 ValueError consistently across platforms.
4576
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004577- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4578 (64bit Unix, for example), unichr() would truncate its argument and return
4579 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4580
Neal Norwitze7d8be82008-07-31 17:17:14 +00004581- Apply security patches from Apple.
4582
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004583- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4584 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4585
Antoine Pitrou92f82162008-07-25 22:22:08 +00004586- Issue #1819: function calls with several named parameters are now on
4587 average 35% faster (as measured by pybench).
4588
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004589- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4590 the python debugger steps into a class statement: the free variables (local
4591 variables defined in an outer scope) would be deleted from the outer scope.
4592
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004593- Issue #2620: Overflow checking when allocating or reallocating memory
4594 was not always being done properly in some python types and extension
4595 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4596 all been updated to perform better checks and places in the code that
4597 would previously leak memory on the error path when such an allocation
4598 failed have been fixed.
4599
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004600Library
4601-------
4602
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004603- Issue #3612: Added some missing basic types in ctypes.wintypes.
4604
Benjamin Petersone977ad42008-08-20 01:42:01 +00004605- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4606 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4607
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004608- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4609 version reported by these tools does not necessarily follow the python
4610 version numbering scheme, so the module is less strict when parsing it.
4611
Nick Coghlanf70385a2008-08-18 12:42:46 +00004612- Issue #2235: Added Py3k warnings for types which will become unhashable
4613 under the stricter __hash__ inheritance rules in 3.0. Several types
4614 which did not meet the rules for hash invariants and were already
4615 unhashable in 3.0 have now been explicitly flagged as unhashable in
4616 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4617 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4618
Brett Cannon88f801d2008-08-18 00:46:22 +00004619- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4620 imported into the module but exposed as part of the module's API.
4621
Brett Cannon7b96f072008-08-18 00:41:11 +00004622- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4623
Brett Cannon46225e72008-08-18 00:36:52 +00004624- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4625
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004626- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4627
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004628- Issue #3575: Incremental decoder's decode function now takes bytearray
4629 by using 's*' instead of 't#'.
4630
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004631- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004632 fails unicode conversion on 2nd parameter. (windows only)
4633
Georg Brandl222e2082010-08-01 22:27:39 +00004634- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004635 in a redirect.
4636
Brett Cannonabe423e2008-08-16 21:47:07 +00004637- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004638 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004639
Facundo Batistaeb90b782008-08-16 14:44:07 +00004640- Issue #2776: fixed small issue when handling an URL with double slash
4641 after a 302 response in the case of not going through a proxy.
4642
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004643- Issue #2676: in the email package, content-type parsing was hanging on
4644 pathological input because of quadratic or exponential behaviour of a
4645 regular expression.
4646
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004647- Issue #3476: binary buffered reading through the new "io" library is now
4648 thread-safe.
4649
Brett Cannonbf3157b2008-08-14 05:00:03 +00004650- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4651 since mimetools itself is deprecated. Because modules are cached, all
4652 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4653
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004654- Issue #3134: shutil referenced undefined WindowsError symbol.
4655
Robert Schuppenies14646332008-08-10 11:01:53 +00004656- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4657 menu entries were not deleted.
4658
Brett Cannon83e81842008-08-09 23:30:55 +00004659- Copied the implementation of reduce() to _functools.reduce() to have a
4660 version that did not raise a DeprecationWarning under -3.
4661
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004662- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4663 a MemoryError rather than silently stop the iteration.
4664
Guido van Rossum59ce9012008-08-09 14:55:34 +00004665- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4666 to _sre.compile() will now be rejected. This should not affect anybody
4667 since the re.compile() function never generates invalid re-bytecode.
4668
Skip Montanaroa032bf42008-08-08 22:52:51 +00004669- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4670 upon first access it can be automatically initialized from the csv file if
4671 it wasn't initialized during instantiation.
4672
Brett Cannon3aa2a492008-08-06 22:28:09 +00004673- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4674 the reload() built-in has been removed.
4675
Brett Cannon7e30b672008-08-04 21:52:25 +00004676- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004677 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004678 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4679 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4680 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4681 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4682 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004683
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004684- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4685 raised an AttributeError.
4686
Benjamin Peterson01a24322008-07-28 23:35:27 +00004687- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004688 asking for a specific length. This problem only affected files opened
4689 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004690
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004691- Issue #3449: Update decimal module to use most recent specification
4692 (v. 1.68) and tests (v. 2.58) from IBM.
4693
Georg Brandl222e2082010-08-01 22:27:39 +00004694- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004695

4698
Georg Brandlf9efabb2008-07-23 15:16:45 +00004699- Deprecate the "ast" parser function aliases.
4700
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004701- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4702
4703- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4704 invalid arguments.
4705
4706- Issue #3302: Fix several crashes when calling locale's gettext functions
4707 with None arguments.
4708
4709- Issue #3389: Allow resolving dotted names for handlers in logging
4710 configuration files.
4711

4713
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004714- Issue #3394: zipfile.writestr sets external attributes when passed a
4715 file name rather than a ZipInfo instance, so files are extracted with
4716 mode 0600 rather than 000 under Unix.
4717
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004718- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4719 argument in python 2.5, this broke code that subclassed Popen to include its
4720 own poll method. Fixed my moving _deadstate to an _internal_poll method.
4721
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00004722Build

4728-------------
4729
Nick Coghlan6e8fef02008-08-18 13:14:22 +00004730- Issue #2235: the C API function PyObject_HashNotImplemented and its
4731 interaction with the tp_hash slot (added in 2.6b2) are now documented
4732
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004733- Issue #643841: The language reference now provides more detailed
4734 coverage of the lookup process for special methods. The disclaimers
4735 regarding lack of coverage of new-style classes have also been
4736 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004739What's New in Python 2.6 beta 2?
4740================================
4741
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004742*Release date: 17-Jul-2008*
4743
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004744Core and Builtins
4745-----------------
4746
Georg Brandl3e483f62008-07-16 22:57:41 +00004747- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4748 its methods now allow for items objects that can be converted to
4749 an integer using operator.index().
4750
Mark Dickinson64b7e502008-07-16 09:40:03 +00004751- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4752 produced a ValueError instead of giving the correct float.
4753
Eric Smitha5fa5a22008-07-16 00:11:49 +00004754- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4755 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4756
Mark Dickinson7103aa42008-07-15 19:08:33 +00004757- Issue #3008: the float type has a new instance method 'float.hex'
4758 and a new class method 'float.fromhex' to convert floating-point
4759 numbers to and from hexadecimal strings, respectively.
4760
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004761- Issue #2235: __hash__ is once again inherited by default. To allow
4762 collections.Hashable to remain meaningful in the presence of the
4763 default hash implementation (object.__hash__), it is now possible
4764 to explicit block inheritance of hash by setting __hash__=None at
4765 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4766 level.
4767
Nick Coghlanb028f502008-07-13 14:52:36 +00004768- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4769 the parent module cannot be found while performing an absolute import.
4770 This means that an incorrectly defined __package__ attribute will
4771 now only prevent relative imports in that module rather than causing
4772 all imports from that module to fail.
4773
Nick Coghlan14ff9942008-07-08 14:21:42 +00004774- Issue #2517: Allow unicode messages in Exceptions again by correctly
4775 bypassing the instance dictionary when looking up __unicode__ on
4776 new-style classes.
4777
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004778- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4779 set to a custom object whose write() method happens to install
4780 another file in sys.stdout.
4781
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004782- Issue #3088: Corrected a race condition in classes derived from
4783 threading.local: the first member set by a thread could be saved in
4784 another thread's dictionary.
4785
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004786- Issue #3004: Minor change to slice.indices(): the start and stop
4787 arguments are now treated identically, making the behaviour easier
4788 to describe and understand. For example, slice(None, -10,
4789 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4790 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4791 10, -1).
4792
Georg Brandl278fc502008-07-19 12:46:12 +00004793- Issue #3219: Calling a function with repeated keyword arguments,
4794 f(a=2, a=23), would not cause a syntax error. This was a regression
4795 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004796
Georg Brandl278fc502008-07-19 12:46:12 +00004797- Issue #2862: Make int and float freelist management consistent with
4798 other freelists. Changes their CompactFreeList apis into
4799 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004800

4803
Thomas Heller57adf222008-08-14 19:10:48 +00004804- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4805 api functions without holding the GIL, which could lead to a fatal
4806 error when they failed.
4807
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004808- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4817 ForkingPickler.register() to resolve conflict with ctypes.
4818
Vinay Sajip51e65192008-07-18 09:01:10 +00004819- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

4822 a valid dlerror() message.
4823
Thomas Heller2bad6572008-07-15 17:19:50 +00004824- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4825 incomplete structure was created.

5244 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005245 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005246
5247 This is controlled by the configure argument ``--with-universal-archs``:
5248
5249 - ``--with-universal-archs=all``: install 4-way universal
5250
5251 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5252
5253 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5254
5255 This option should be used in combination with ``--enable-universalsdk=``.
5256
5257 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

5294 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005295
Christian Heimese74c8f22008-04-19 02:23:57 +00005296- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5297
Georg Brandl3ee81df2008-05-17 18:14:43 +00005298- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
5299 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00005300
Georg Brandl3ee81df2008-05-17 18:14:43 +00005301- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00005307- Issue #1631171: Re-implement the 'warnings' module in C (the
5308 original Python code has been kept as backup). This will allow for
5309 using the 'warning's machinery in such places as the parser where
5310 use of pure Python code is not possible. Both the ``showarning()``
5311 and ``formatwarning()`` gain an optional 'line' argument which is
5312 not called by default for backwards-compatibility reasons. Setting
5313 ``warnings.showwarning()`` to an implementation that lacks support
5314 for the ``line`` argument will raise a DeprecationWarning.

5338
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005339- The getpass module has been improved on Unix. It now uses /dev/tty
5340 by default and uses stderr instead of stdout. A GetPassWarning is
5341 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00005342

Georg Brandl3ee81df2008-05-17 18:14:43 +00005356- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005357 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005377- Issue #2550: The approach used by client/server code for obtaining
5378 ports to listen on in network-oriented tests has been refined in an
5379 effort to facilitate running multiple instances of the entire
5380 regression test suite in parallel without issue.
5381 test_support.bind_port() has been fixed such that it will always
5382 return a unique port -- which wasn't always the case with the
5383 previous implementation, especially if socket options had been set
5384 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5385 new implementation of bind_port() will actually raise an exception
5386 if it is passed an AF_INET/SOCK_STREAM socket with either the
5387 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5388 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5389 the socket it's been passed. This currently only applies to
5390 Windows. This option prevents any other sockets from binding to the
5391 host/port we've bound to, thus removing the possibility of the
5392 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5393 when a second SOCK_STREAM socket binds and accepts to a host/port
5394 that's already been bound by another socket. The optional preferred
5395 port parameter to bind_port() has been removed. Under no
5396 circumstances should tests be hard coding ports!
5397
5398 test_support.find_unused_port() has also been introduced, which will
5399 pass a temporary socket object to bind_port() in order to obtain an
5400 unused port. The temporary socket object is then closed and
5401 deleted, and the port is returned. This method should only be used
5402 for obtaining an unused port in order to pass to an external program
5403 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5404 a parameter to a server-oriented class that doesn't give you direct
5405 access to the underlying socket used.
5406
5407 Finally, test_support.HOST has been introduced, which should be used
5408 for the host argument of any relevant socket calls (i.e. bind and
5409 connect).

5685
Fred Drakea8ee94b2008-03-01 02:45:07 +00005686- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005687 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005688
Georg Brandlad61bc82008-02-23 15:11:18 +00005689- Issue #2067: file.__exit__() now calls subclasses' close() method.
5690
5691- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005692
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005693- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005694 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005695
Eric Smitha73fbe72008-02-23 03:09:44 +00005696- Added the future_builtins module, which contains hex() and oct().
5697 These are the PEP 3127 version of these functions, designed to be
5698 compatible with the hex() and oct() builtins from Python 3.0. They
5699 differ slightly in their output formats from the existing, unchanged
5700 Python 2.6 builtins. The expected usage of the future_builtins
5701 module is:
5702 from future_builtins import hex, oct
5703
Eric Smith7ef40bf2008-02-20 23:34:22 +00005704- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5705 exponents for exponents with absolute value < 100. Follows C99
5706 standard. This is a change on Windows, which would use 3 digits.
5707 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5708 so that any alterations it does to the resulting string will be
5709 available in stringlib/formatter.h (for float.__format__).
5710
Eric Smith5a3c1352008-02-19 13:21:56 +00005711- Implemented PEP 3101, Advanced String Formatting. This adds a new
5712 builtin format(); a format() method for str and unicode; a
5713 __format__() method to object, str, unicode, int, long, float, and
5714 datetime; the class string.Formatter; and the C API
5715 PyObject_Format().
5716
Georg Brandl3ee81df2008-05-17 18:14:43 +00005717- Fixed several potential crashes, all caused by specially crafted
5718 __del__ methods exploiting objects in temporarily inconsistent
5719 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005720
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005721- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005722 prevent a possible crash: an Abstract Base Class would try to access
5723 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005724
Georg Brandl3ee81df2008-05-17 18:14:43 +00005725- Fixed repr() and str() of complex numbers with infinity or nan as
5726 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005727
Georg Brandl3ee81df2008-05-17 18:14:43 +00005728- Clear all free lists during a gc.collect() of the highest generation
5729 in order to allow pymalloc to free more arenas. Python may give back
5730 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005731
Georg Brandl3ee81df2008-05-17 18:14:43 +00005732- Issue #2045: Fix an infinite recursion triggered when printing a
5733 subclass of collections.defaultdict, if its default_factory is set
5734 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005735
Christian Heimesf75dbef2008-02-08 00:11:31 +00005736- Fixed a minor memory leak in dictobject.c. The content of the free
5737 list was not freed on interpreter shutdown.
5738
Georg Brandl21e99f42010-03-07 15:23:59 +00005739- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005740 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005741
Georg Brandl3ee81df2008-05-17 18:14:43 +00005742- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5743 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005744 to compact the internal free lists of pre-allocted ints and floats.
5745
Georg Brandl3ee81df2008-05-17 18:14:43 +00005746- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5747 calls. Python expected the return type int but the fork familie
5748 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005749
Georg Brandl3ee81df2008-05-17 18:14:43 +00005750- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5751 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005752
Georg Brandl3ee81df2008-05-17 18:14:43 +00005753- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5754 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005755
Georg Brandl3ee81df2008-05-17 18:14:43 +00005756- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5757 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005758
Georg Brandl3ee81df2008-05-17 18:14:43 +00005759- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5760 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005761
Georg Brandl3ee81df2008-05-17 18:14:43 +00005762- Patch #1473257: generator objects gain a gi_code attribute. This is
5763 the same object as the func_code attribute of the function that
5764 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005765
Georg Brandl3ee81df2008-05-17 18:14:43 +00005766- Issue #1920: "while 0" statements were completely removed by the
5767 compiler, even in the presence of an "else" clause, which is
5768 supposed to be run when the condition is false. Now the compiler
5769 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005770
Guido van Rossumeead05f2008-01-24 18:21:02 +00005771- A few crashers fixed: weakref_in_del.py (issue #1377858);
5772 loosing_dict_ref.py (issue #1303614, test67.py);
5773 borrowed_ref_[34].py (not in tracker).
5774
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005775- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005776 suppressed while an extension is loaded by calling SetErrorMode in
5777 dynload_win.c. The error is still reported properly.
5778
Georg Brandl3ee81df2008-05-17 18:14:43 +00005779- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005780 several extension methods and modules do not work without unicode
5781 support.
5782
Georg Brandl26543b12008-01-21 18:36:51 +00005783- Issue #1882: when compiling code from a string, encoding cookies in the
5784 second line of code were not always recognized correctly.
5785
Georg Brandl14404b62008-01-19 19:27:05 +00005786- Issue #1679: "0x" was taken as a valid integer literal.
5787
Georg Brandl6caad7d2008-01-26 14:19:22 +00005788- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005789 added.
5790
Christian Heimesc94e2b52008-01-14 04:13:37 +00005791- sys.float_info / PyFloat_GetInfo: The floating point information
5792 object was converted from a dict to a specialized structseq object.
5793
Georg Brandl3ee81df2008-05-17 18:14:43 +00005794- Patch #1816: Added sys.flags structseq. It exposes the status of
5795 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005796
Georg Brandl3ee81df2008-05-17 18:14:43 +00005797- Objects/structseq.c: Implemented new structseq representation. The
5798 patch makes structseqs (e.g. the return value of os.stat) more
5799 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005800
Georg Brandl3ee81df2008-05-17 18:14:43 +00005801- Patch #1700288: added a type attribute cache that caches method
5802 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005803
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005804- Bug #1776: __import__() no longer accepts filenames on any platform.
5805 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005806

5808
Georg Brandl3ee81df2008-05-17 18:14:43 +00005809- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5810 envvar and sys.dont_write_bytecode attribute. All these can be set
5811 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005812
Georg Brandl3ee81df2008-05-17 18:14:43 +00005813- Improve some exception messages when Windows fails to load an
5814 extension module. Now we get for example '%1 is not a valid Win32
5815 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005816
Georg Brandl3ee81df2008-05-17 18:14:43 +00005817- Bug #1481296: Fixed long(float('nan')) != 0L.

5820 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005821
Christian Heimes0a8143f2007-12-18 23:22:54 +00005822- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005823 and INF. float("nan"), float("inf") and float("-inf") now work on
5824 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005825
Georg Brandl3ee81df2008-05-17 18:14:43 +00005826- Compiler now generates simpler and faster code for dictionary
5827 literals. The oparg for BUILD_MAP now indicates an estimated
5828 dictionary size. There is a new opcode, STORE_MAP, for adding
5829 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005863- Issue #1265: Fix a problem with sys.settrace, if the tracing
5864 function uses a generator expression when at the same time the
5865 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005866
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005867- sets and frozensets now have an isdisjoint() method.

5872
Georg Brandl21e99f42010-03-07 15:23:59 +00005873- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005874 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5875 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005876
Georg Brandl3ee81df2008-05-17 18:14:43 +00005877- Issue #1686386: Tuple's tp_repr did not take into account the
5878 possibility of having a self-referential tuple, which is possible
5879 from C code. Nor did object's tp_str consider that a type's tp_str
5880 could do something that could lead to an inifinite recursion.
5881 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5882 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005883
Georg Brandl3ee81df2008-05-17 18:14:43 +00005884- Issue #1164: It was possible to trigger deadlock when using the

5886 as needed. Now PyObject_Print() does the right thing along with
5887 various tp_print implementations of the built-in types and those in
5888 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005890- Issue #1147: Exceptions were directly allowing string exceptions in
5891 their throw() method even though string exceptions no longer
5892 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005894- Issue #1096: Prevent a segfault from getting the repr of a very
5895 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005896
Brett Cannon1e534b52007-09-07 04:18:30 +00005897- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005898 PyObject_Call() never calling back out to Python code to trigger
5899 recursion depth updates/checks. Required the creation of a static
5900 RuntimeError instance in case normalizing an exception put the
5901 recursion check value past its limit. Fixes crashers
5902 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005917- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005918 __*__ attributes. (Some already existed, e.g., __doc__ and
5919 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005920
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005921- Add -3 option to the interpreter to warn about features that are

5925 calls.
5926
Collin Winter62903052007-05-18 23:11:24 +00005927- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005928 "except E as target:". This is to provide forwards compatibility
5929 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005930
Brett Cannon229cee22007-05-05 01:34:02 +00005931- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005936- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005937 setting a plain string, ie don't expand to single letter identifiers.
5938
Raymond Hettinger13936692007-04-11 18:40:58 +00005939- Request #1191699: Slices can now be pickled.
5940
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005941- Request #1193128: str.translate() now allows a None argument for
5942 translations that only remove characters without re-mapping the
5943 remaining characters.
5944
Georg Brandl5cb76c12007-03-21 09:00:39 +00005945- Patch #1682205: a TypeError while unpacking an iterable is no longer

5949
Guido van Rossum143b5642007-03-23 04:58:42 +00005950- Bug #1683368: The object.__init__() and object.__new__() methods are
5951 now stricter in rejecting excess arguments. The only time when
5952 either allows excess arguments is when it is not overridden and the
5953 other one is. For backwards compatibility, when both are
5954 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005955 warning later). Also, type.__init__() insists on the same signature
5956 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005957
Georg Brandl3ee81df2008-05-17 18:14:43 +00005958- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5959 object to complex using its __complex__() method before falling back
5960 to the __float__() method. Therefore, the functions in the cmath
5961 module now can operate on objects that define a __complex__()
5962 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005980- Bug #1678647: write a newline after printing an exception in any
5981 case, even when converting the value to a string failed.
5982
Georg Brandl871f1bc2007-03-12 13:17:36 +00005983- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005984 its argument, if it exists. If not, it will work like before. This
5985 allows customizing the output of dir() in the presence of a
5986 __getattr__().

5995 parthensized forms. This means complex(repr(x)) now works instead of
5996 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005997
Georg Brandlaa2321b2007-03-07 00:40:28 +00005998- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005999 makes the filenames the warning module prints much more sensible
6000 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006013- Patch #1674228: when assigning a slice (old-style), check for the
6014 sq_ass_slice instead of the sq_slice slot.
6015
Georg Brandl3ee81df2008-05-17 18:14:43 +00006016- When printing an unraisable error, don't print exceptions. before

6627 Python would crash instead of raising an error.
6628

6641
Georg Brandl3ee81df2008-05-17 18:14:43 +00006642- unittest now verifies more of its assumptions. In particular,

6644 accepted in TestSuite.addTest(). This should cause no
6645 incompatibility since it never made sense with ordinary subclasses
6646 -- the failure just occurred later, with a more cumbersome
6647 exception.

6931 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006932
Georg Brandl3ee81df2008-05-17 18:14:43 +00006933- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006934 that the SMTP.starttls() caller no longer needs to call ehlo()
6935 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006936 does not claim to support starttls. Adds the
6937 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00007036 time so that opening a database previously created with the DB_DUP
7037 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7038 opens. Specifically: dictionary assignment to a DB object will
7039 replace all values for a given key when the database allows
7040 duplicate values. DB users should use DB.put(k, v) when they want
7041 to store duplicates; not DB[k] = v.

7048 characters with ASCII value less than 32. Also, it correctly quotes
7049 dots only if they occur on a single line, as opposed to the previous
7050 behavior of quoting dots if they are the second character of any
7051 line.

7374-----
7375
Georg Brandl3ee81df2008-05-17 18:14:43 +00007376- Unified naming convention for free lists and their limits. All free
7377 lists in Object/ are named ``free_list``, the counter ``numfree``
7378 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7379 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007380
Georg Brandl3ee81df2008-05-17 18:14:43 +00007381- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7382 to ``PyTuple_SetItem``, it can be used to populate a brand new
7383 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007384
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007385- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007387- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7388 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7389 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007390
7391- Patch #1720595: add T_BOOL to the range of structmember types.
7392
7393- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7394 ``PyFloat_GetInfo()`` to the float API.
7395
Georg Brandl3ee81df2008-05-17 18:14:43 +00007396- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7397 of w# format code incorrectly truncated the length to an int, even
7398 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7399 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007400
Georg Brandl3ee81df2008-05-17 18:14:43 +00007401- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7402 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007403
Georg Brandl3ee81df2008-05-17 18:14:43 +00007404- PEP 3123: Provide forward compatibility with Python 3.0, while
7405 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7406 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007407
Georg Brandl3ee81df2008-05-17 18:14:43 +00007408- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7409 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007410
7411- Patch #1733960: Allow T_LONGLONG to accept ints.
7412
7413- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7414
Christian Heimes000a0742008-01-03 22:16:32 +00007415- Added a new API function ``PyImport_ImportModuleNoBlock``.

7418
7419- Fix some leftovers from the conversion from int to Py_ssize_t
7420 (relevant to strings and sequences of more than 2**31 items).
7421
7422- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7423 outside of pystate.c and should not be necessary.
7424
Georg Brandl3ee81df2008-05-17 18:14:43 +00007425- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7426 absolute imports. In earlier versions they might have used relative
7427 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007428
Georg Brandl3ee81df2008-05-17 18:14:43 +00007429- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7430 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007431
Georg Brandl3ee81df2008-05-17 18:14:43 +00007432- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7433 macro so it can be used as an expression.

7438
Georg Brandl3ee81df2008-05-17 18:14:43 +00007439- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7440 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7441 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7442 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007443
Georg Brandl3ee81df2008-05-17 18:14:43 +00007444- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00007457- Removed the macfs module. It had been deprecated since Python 2.5.
7458 This lead to the deprecation of macostools.touched() as it relied
7459 solely on macfs and was a no-op under OS X.
