Mark Dickinsondbbed042011-09-19 16:38:08 +010036- Issue #12973: Fix overflow checks that invoked undefined behaviour in
37 int.__pow__. These overflow checks were causing int.__pow__ to produce
38 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010039 compiler optimizing the check away. Also fix similar overflow checks
40 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
41 bugs caused test failures with recent versions of Clang.

53 cleared by the garbage collector. This fixes a segfault when an instance
54 and its type get caught in a reference cycle, and the instance's
55 deallocator calls one of the methods on the type (e.g. when subclassing
56 IOBase). Diagnosis and patch by Davide Rizzo.

238
Ned Deily87e82bb2011-06-28 19:52:59 -0700239- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
240 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
241 interpreter process. This could cause failures in non-Distutils subprocesses
242 and was unreliable since tests or user programs could modify the interpreter
243 environment after Distutils set it. Instead, have Distutils set the the
244 deployment target only in the environment of each build subprocess. It is
245 still possible to globally override the default by setting
246 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
247 greater or equal to the default value, the value with which the interpreter
248 was built.

275
Barry Warsawc5643282011-07-19 17:06:30 -0400276- sys.setcheckinterval() now updates the current ticker count as well as
277 updating the check interval, so if the user decreases the check interval,
278 the ticker doesn't have to wind down to zero from the old starting point
279 before the new interval takes effect. And if the user increases the
280 interval, it makes sure the new limit takes effect right away rather have an
281 early task switch before recognizing the new interval.
Raymond Hettinger19b851d2011-06-01 18:21:42 -0700282

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001642- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1643 start byte and the continuation byte(s) are now considered invalid, instead
1644 of the number of bytes specified by the start byte.
1645 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1646 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1657 objects. (1) The comparison could incorrectly return True in some cases
1658 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1659 (2) The comparison raised an OverflowError for large integers, leading

1855 operation raises multiple signals and more than one of those signals is
1856 trapped, the specification determines the order in which the signals should be

Georg Brandlfee0f442010-05-22 21:26:21 +00002002- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002003 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2004 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2005 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2025Core and Builtins
2026-----------------
2027
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002028- Issue #7301: Add environment variable $PYTHONWARNINGS.
2029
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002030- Issue #8329: Don't return the same lists from select.select when no fds are
2031 changed.
2032
Georg Brandlfee0f442010-05-22 21:26:21 +00002033- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002034 on 64-bit machines. The shift count for either left or right shift is
2035 permitted to be up to sys.maxsize.
2036
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002037- Ensure that tokenization of identifiers is not affected by locale.
2038
Georg Brandlfee0f442010-05-22 21:26:21 +00002039- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002040
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002041- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2042
Georg Brandlfee0f442010-05-22 21:26:21 +00002043- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2044 with a non-empty format string. This is an effort to future-proof user
2045 code. If a derived class does not currently implement __format__ but later
2046 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002047 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002048 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002049
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002050- Issue #8268: Old-style classes (not just instances) now support weak
2051 references.
2052
Georg Brandlfee0f442010-05-22 21:26:21 +00002053- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2054 is set.

Benjamin Peterson96545892010-03-21 20:21:00 +00002058- Issue #6474: Make error message from passing an inadequate number of keyword
2059 arguments to a function correct.
2060
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002061- Issue #8164: Don't allow lambda functions to have a docstring.
2062
Victor Stinner66644262010-03-10 22:30:19 +00002063- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002064 (SIGINT). If an error occurs while importing the site module, the error is
2065 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002066 module.

2074
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002075- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002076 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2077 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002079- Issue #8310: Allow dis to examine new style classes.
2080
Georg Brandlfee0f442010-05-22 21:26:21 +00002081- Issue #8257: The Decimal construct now accepts a float instance directly,
2082 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002083
2084 >>> Decimal(1.1)
2085 Decimal('1.100000000000000088817841970012523233890533447265625')
2086
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002087- collections.Counter() now supports a subtract() method.
2088
Georg Brandlfee0f442010-05-22 21:26:21 +00002089- The functools module now has a total_ordering() class decorator to simplify
2090 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002091
Georg Brandlfee0f442010-05-22 21:26:21 +00002092- The functools module also adds cmp_to_key() as a tool to transition old-style
2093 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002094
Georg Brandlfee0f442010-05-22 21:26:21 +00002095- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2096 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002097
Georg Brandlfee0f442010-05-22 21:26:21 +00002098- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2099 InvalidOperation instead of returning False. (Comparisons involving a quiet
2100 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2101 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002102
Georg Brandlfee0f442010-05-22 21:26:21 +00002103- Issue #2531: Comparison operations between floats and Decimal instances now
2104 return a result based on the numeric values of the operands; previously they
2105 returned an arbitrary result based on the relative ordering of id(float) and
2106 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002107
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002108- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002109 argument `-` which tells it to read files to compile from stdin. Each line is
2110 read on demand and the named file is compiled immediately. (Original patch by
2111 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002112
Georg Brandlfee0f442010-05-22 21:26:21 +00002113- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2114 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002116- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2117 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002118 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002119
Georg Brandlfee0f442010-05-22 21:26:21 +00002120- Comparisons using one of <, <=, >, >= between a complex instance and a
2121 Fractions instance now raise TypeError instead of returning True/False. This
2122 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2123 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002124
Michael Foorde6410c52010-03-29 20:04:23 +00002125- Addition of ``WeakSet`` to the ``weakref`` module.

2133
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002134- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002135 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2136 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002137
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002138- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2139 deprecated.
2140
Georg Brandlfee0f442010-05-22 21:26:21 +00002141- Issue #7860: platform.uname now reports the correct 'machine' type when Python

2148 existing at the same time, causing a Unicode error when configuration code
2149 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00002150
Georg Brandlfee0f442010-05-22 21:26:21 +00002151- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded

2155 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
2156 reads and writes are always retried by OpenSSL itself.

2164 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +00002165
Matthias Klose8b411682010-03-16 10:48:52 +00002166- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
2167 with Tcl/Tk-8.5.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002178- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002179 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2180 log file to compute the next rollover time. If the log file does not exist,
2181 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002182
Georg Brandlba83f822010-03-14 09:50:54 +00002183- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00002191- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2192 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2193 This is a behavior change, so email's minor version number is now bumped, to
2194 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002222- Issue #8300: When passing a non-integer argument to struct.pack with any
2223 integer format code, struct.pack first attempts to convert the non-integer
2224 using its __index__ method. If that method is non-existent or raises
2225 TypeError it goes on to try the __int__ method, as described below.
2226
Georg Brandlba83f822010-03-14 09:50:54 +00002227- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2228 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2229 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002230 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2231 inconsistent: __int__ was used for some integer codes but not for others, and
2232 the set of integer codes for which it was used differed between native packing

2465 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002466 library would return a bogus result; on Solaris, it was possible to crash the

2487 returning NULL. The macro now returns a statically allocated empty string
2488 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002541 file position when calling `truncate()`. It would previously change the file
2542 position to the given argument, which goes against the tradition of

2546 class used to represent files stored inside an archive. The new
2547 implementation is significantly faster and can be wrapped in a
2548 ``io.BufferedReader`` object for more speedups. It also solves an issue
2549 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2562 encoded string for them. This ensures that the upload and register commands
2563 send the correct values to PyPI without any error.

2638-----------------
2639
Georg Brandlba83f822010-03-14 09:50:54 +00002640- The ``__complex__()`` method is now looked up on the class of instances to
2641 make it consistent with other special methods.

2645
Mark Dickinson1b34d252010-01-01 17:27:30 +00002646- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002647 DeprecationWarning when passed a float argument where an integer was expected.
2648 These functions and methods now raise TypeError instead. The majority of the
2649 effects of this change are in the extension modules, but some core functions
2650 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2651 and many unicode/str methods.

2665 of integers: the result of a/b is now correctly rounded for ints a and b (at
2666 least on IEEE 754 platforms), and in particular does not depend on the
2667 internal representation of a long.

2675
Georg Brandlba83f822010-03-14 09:50:54 +00002676 These executables now work properly with the arch(1) command: ``arch -ppc
2677 python`` will start a universal binary version of python in PPC mode (unlike

2818 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002819
Georg Brandlba83f822010-03-14 09:50:54 +00002820- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2821 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002822

Georg Brandlba83f822010-03-14 09:50:54 +00002834- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2835 decimal string that's guaranteed to round back to x under correct rounding
2836 (with round-half-to-even rounding mode). Previously it gave a string based on
2837 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2838 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2839 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002840
Georg Brandlba83f822010-03-14 09:50:54 +00002841- Issue #7117: On almost all platforms: float-to-string and string-to-float
2842 conversions within Python are now correctly rounded. Places these conversions
2843 occur include: str for floats and complex numbers; the float and complex
2844 constructors; old-style and new-style numeric formatting; serialization and
2845 deserialization of floats and complex numbers using marshal, pickle and json;
2846 parsing of float and imaginary literals in Python code; Decimal-to-float
2847 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002848
Georg Brandlba83f822010-03-14 09:50:54 +00002849 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2850 providing correctly-rounded strtod and dtoa C functions. This code is
2851 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2852 the C compiler. There may be a small number of platforms on which correct
2853 operation of this code cannot be guaranteed, so the code is not used: notably,
2854 this applies to platforms where the C double format is not IEEE 754 binary64,
2855 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2856 and Python's configure script is unable to determine how to change the FPU
2857 precision. On these platforms conversions use the platform strtod and dtoa,
2858 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002860- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2861 uses the correctly-rounded string <-> float conversions described above (when
2862 available), and so produces correctly rounded results that will display nicely
2863 under the float repr. There are two related small changes: (1) round now
2864 accepts any class with an ``__index__()`` method for its second argument (but
2865 no longer accepts floats for the second argument), and (2) an excessively
2866 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2867 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003009
Georg Brandlba83f822010-03-14 09:50:54 +00003010 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3011 (2) parsing of strings representing infinities and nans was locale aware; and
3012 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003014- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3015 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3016 but with at least one decimal point and with a default precision
3017 of 12. Previously, the behavior the same but with a default precision of 6.
3018 This more closely matches ``str()``, and reduces surprises when adding
3019 alignment flags to the empty presentation type. This also affects the new
3020 complex.__format__ in the same way.
3021
3022- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3023 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00003085 untrackable objects are not tracked by the garbage collector. This can reduce

3094 internal representation of integers, for performance reasons. Base 2**30 is
3095 enabled by default on 64-bit machines. Add --enable-big-digits option to

3182
Georg Brandl6425a2f2008-12-28 11:54:53 +00003183- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003184 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003185
Skip Montanarof205c132008-12-23 03:30:15 +00003186- Added test case to ensure attempts to read from a file opened for writing
3187 fail.
3188
Georg Brandlba83f822010-03-14 09:50:54 +00003189- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print

Georg Brandlba83f822010-03-14 09:50:54 +00003203- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3204 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3205 instances. On a typical machine this saves 3 bytes of memory (on average) per
3206 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003208- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3209 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3210 instead of throwing a MemoryError.
3211
Georg Brandlba83f822010-03-14 09:50:54 +00003212- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00003215- Issue #4367: Python would segfault during compiling when the unicodedata

3217
Georg Brandlba83f822010-03-14 09:50:54 +00003218- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3219 file objects with closefd=False. The file descriptor is still kept open but
3220 the file object behaves like a closed file. The ``FileIO`` object also got a
3221 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003223- Issue #4348: Some bytearray methods returned that didn't cause any change to
3224 the bytearray, returned the same bytearray instead of a copy.
3225
Georg Brandlba83f822010-03-14 09:50:54 +00003226- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00003238- Issue #4209: Enabling unicode_literals and the print_function in the same
3239 __future__ import didn't work.
3240
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003241- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003242 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003243
Georg Brandlba83f822010-03-14 09:50:54 +00003244- On windows, ``os.chdir()`` given unicode was not working if
3245 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3246 this code path is really executed because I cannot move to such directory on
3247 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003248
Georg Brandlba83f822010-03-14 09:50:54 +00003249- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3250 element is temporarily replaced with an equivalent frozenset. But the
3251 eventual KeyError would always report the empty ``frozenset()`` as the missing
3252 key. Now it correctly refers to the initial element.

3270 returned them on 64bit platforms.
3271
Walter Dörwalded960ac2009-05-03 22:36:33 +00003272- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3273 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3274 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3275 of using the replace error handler in PyUnicode_DecodeUTF8().
3276
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003277- Issue #3739: The unicode-internal encoder now reports the number of characters
3278 consumed like any other encoder (instead of the number of bytes).
3279
Georg Brandlba83f822010-03-14 09:50:54 +00003280- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3281 allocator will be automatically disabled when running under Valgrind. This
3282 gives improved memory leak detection when running under Valgrind, while taking
3283 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004527 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4528 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00004530- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
4531 regression tests in parallel, shortening the total runtime.
4532
Georg Brandlba83f822010-03-14 09:50:54 +00004533- Issue #5354: New test support function import_fresh_module() makes it easy to
4534 import both normal and optimised versions of modules. test_heapq and
4535 test_warnings have been adjusted to use it, tests for other modules with both
4536 C and Python implementations in the stdlib can be adjusted to use it over
4537 time.

Georg Brandlba83f822010-03-14 09:50:54 +00004545- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4546 should cause a test to be skipped are now done using import_module from test
4547 support, which does the conversion.

4649
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004650- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4651 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4652 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4653 ``printf`` function, whereas PyString_FromFormat has an independent
4654 implementation and uses "%zd" on all platforms for size_t values.
4655 This makes a difference on win64, where ``printf`` needs "%Id" to display
4656 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004658- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4662 object; previously an int would be returned for small values. the __long__
4663 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00004672 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004673 was correctly parsed but parsing of subsequent arguments failed.
4674
Vinay Sajip35e3b032008-09-01 14:33:59 +00004675- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004676 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4677 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4678 when given a tuple of classes as second argument, were looking up
4679 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4680 type object.
4681

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004819What's New in Python 2.6 beta 3?
4820================================
4821
Barry Warsaw07a4a382008-08-21 01:15:08 +00004822*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004823
4824Core and Builtins
4825-----------------
4826
Guido van Rossumf8402962008-08-20 15:01:50 +00004827- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4828 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4829 extensions do not automatically benefit from the class attribute
4830 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4831 to their tp_flags field if they care. This is a backwards
4832 compatibility feature; in 3.0, all types will use the cache by
4833 default.
4834
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004835- Keyword arguments can now follow starred arguments. (``f(a, *args,
4836 keyword=23)`` is now valid syntax.)
4837
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004838- ctypes function pointers that are COM methods have a boolean True
4839 value again.
4840
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004841- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4842 by denying s# to parse objects that have a releasebuffer procedure,
4843 and introducing s*.
4844
Georg Brandl1e13ea92008-08-11 09:07:59 +00004845- Issue #3537: Fix an assertion failure when an empty but presized dict
4846 object was stored in the freelist.
4847
Mark Dickinsonb6467572008-08-04 21:30:09 +00004848- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4849 ValueError consistently across platforms.
4850
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004851- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4852 (64bit Unix, for example), unichr() would truncate its argument and return
4853 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4854
Neal Norwitze7d8be82008-07-31 17:17:14 +00004855- Apply security patches from Apple.
4856
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004857- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4858 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4859
Antoine Pitrou92f82162008-07-25 22:22:08 +00004860- Issue #1819: function calls with several named parameters are now on
4861 average 35% faster (as measured by pybench).
4862
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004863- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4864 the python debugger steps into a class statement: the free variables (local
4865 variables defined in an outer scope) would be deleted from the outer scope.
4866
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004867- Issue #2620: Overflow checking when allocating or reallocating memory
4868 was not always being done properly in some python types and extension
4869 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4870 all been updated to perform better checks and places in the code that
4871 would previously leak memory on the error path when such an allocation
4872 failed have been fixed.
4873
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004874Library
4875-------
4876
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004877- Issue #3612: Added some missing basic types in ctypes.wintypes.
4878
Benjamin Petersone977ad42008-08-20 01:42:01 +00004879- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4880 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4881
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004882- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4883 version reported by these tools does not necessarily follow the python
4884 version numbering scheme, so the module is less strict when parsing it.
4885
Nick Coghlanf70385a2008-08-18 12:42:46 +00004886- Issue #2235: Added Py3k warnings for types which will become unhashable
4887 under the stricter __hash__ inheritance rules in 3.0. Several types
4888 which did not meet the rules for hash invariants and were already
4889 unhashable in 3.0 have now been explicitly flagged as unhashable in
4890 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4891 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4892
Brett Cannon88f801d2008-08-18 00:46:22 +00004893- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4894 imported into the module but exposed as part of the module's API.
4895
Brett Cannon7b96f072008-08-18 00:41:11 +00004896- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4897
Brett Cannon46225e72008-08-18 00:36:52 +00004898- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4899
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004900- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4901
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004902- Issue #3575: Incremental decoder's decode function now takes bytearray
4903 by using 's*' instead of 't#'.
4904
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004905- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004906 fails unicode conversion on 2nd parameter. (windows only)
4907
Georg Brandl222e2082010-08-01 22:27:39 +00004908- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004909 in a redirect.
4910
Brett Cannonabe423e2008-08-16 21:47:07 +00004911- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004912 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004913
Facundo Batistaeb90b782008-08-16 14:44:07 +00004914- Issue #2776: fixed small issue when handling an URL with double slash
4915 after a 302 response in the case of not going through a proxy.
4916
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004917- Issue #2676: in the email package, content-type parsing was hanging on
4918 pathological input because of quadratic or exponential behaviour of a
4919 regular expression.
4920
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004921- Issue #3476: binary buffered reading through the new "io" library is now
4922 thread-safe.
4923
Brett Cannonbf3157b2008-08-14 05:00:03 +00004924- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4925 since mimetools itself is deprecated. Because modules are cached, all
4926 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4927
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004928- Issue #3134: shutil referenced undefined WindowsError symbol.
4929
Robert Schuppenies14646332008-08-10 11:01:53 +00004930- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4931 menu entries were not deleted.
4932
Brett Cannon83e81842008-08-09 23:30:55 +00004933- Copied the implementation of reduce() to _functools.reduce() to have a
4934 version that did not raise a DeprecationWarning under -3.
4935
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004936- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4937 a MemoryError rather than silently stop the iteration.
4938
Guido van Rossum59ce9012008-08-09 14:55:34 +00004939- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4940 to _sre.compile() will now be rejected. This should not affect anybody
4941 since the re.compile() function never generates invalid re-bytecode.
4942
Skip Montanaroa032bf42008-08-08 22:52:51 +00004943- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4944 upon first access it can be automatically initialized from the csv file if
4945 it wasn't initialized during instantiation.
4946
Brett Cannon3aa2a492008-08-06 22:28:09 +00004947- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4948 the reload() built-in has been removed.
4949
Brett Cannon7e30b672008-08-04 21:52:25 +00004950- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004951 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004952 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4953 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4954 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4955 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4956 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004957
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004958- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4959 raised an AttributeError.
4960
Benjamin Peterson01a24322008-07-28 23:35:27 +00004961- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004962 asking for a specific length. This problem only affected files opened
4963 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004964
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004965- Issue #3449: Update decimal module to use most recent specification
4966 (v. 1.68) and tests (v. 2.58) from IBM.
4967
Georg Brandl222e2082010-08-01 22:27:39 +00004968- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004969

4972
Georg Brandlf9efabb2008-07-23 15:16:45 +00004973- Deprecate the "ast" parser function aliases.
4974
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004975- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4976
4977- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4978 invalid arguments.
4979
4980- Issue #3302: Fix several crashes when calling locale's gettext functions
4981 with None arguments.
4982

4987
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004988- Issue #3394: zipfile.writestr sets external attributes when passed a
4989 file name rather than a ZipInfo instance, so files are extracted with
4990 mode 0600 rather than 000 under Unix.
4991
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004992- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4993 argument in python 2.5, this broke code that subclassed Popen to include its
4994 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5002-------------
5003
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005004- Issue #2235: the C API function PyObject_HashNotImplemented and its
5005 interaction with the tp_hash slot (added in 2.6b2) are now documented
5006
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005007- Issue #643841: The language reference now provides more detailed
5008 coverage of the lookup process for special methods. The disclaimers
5009 regarding lack of coverage of new-style classes have also been
5010 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005013What's New in Python 2.6 beta 2?
5014================================
5015
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005016*Release date: 17-Jul-2008*
5017
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005018Core and Builtins
5019-----------------
5020
Georg Brandl3e483f62008-07-16 22:57:41 +00005021- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5022 its methods now allow for items objects that can be converted to
5023 an integer using operator.index().
5024
Mark Dickinson64b7e502008-07-16 09:40:03 +00005025- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5026 produced a ValueError instead of giving the correct float.
5027
Eric Smitha5fa5a22008-07-16 00:11:49 +00005028- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5029 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5030
Mark Dickinson7103aa42008-07-15 19:08:33 +00005031- Issue #3008: the float type has a new instance method 'float.hex'
5032 and a new class method 'float.fromhex' to convert floating-point
5033 numbers to and from hexadecimal strings, respectively.
5034
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005035- Issue #2235: __hash__ is once again inherited by default. To allow
5036 collections.Hashable to remain meaningful in the presence of the
5037 default hash implementation (object.__hash__), it is now possible
5038 to explicit block inheritance of hash by setting __hash__=None at
5039 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5040 level.
5041
Nick Coghlanb028f502008-07-13 14:52:36 +00005042- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5043 the parent module cannot be found while performing an absolute import.
5044 This means that an incorrectly defined __package__ attribute will
5045 now only prevent relative imports in that module rather than causing
5046 all imports from that module to fail.
5047
Nick Coghlan14ff9942008-07-08 14:21:42 +00005048- Issue #2517: Allow unicode messages in Exceptions again by correctly
5049 bypassing the instance dictionary when looking up __unicode__ on
5050 new-style classes.
5051
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005052- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5053 set to a custom object whose write() method happens to install
5054 another file in sys.stdout.
5055
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005056- Issue #3088: Corrected a race condition in classes derived from
5057 threading.local: the first member set by a thread could be saved in
5058 another thread's dictionary.
5059
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005060- Issue #3004: Minor change to slice.indices(): the start and stop
5061 arguments are now treated identically, making the behaviour easier
5062 to describe and understand. For example, slice(None, -10,
5063 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5064 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5065 10, -1).
5066
Georg Brandl278fc502008-07-19 12:46:12 +00005067- Issue #3219: Calling a function with repeated keyword arguments,
5068 f(a=2, a=23), would not cause a syntax error. This was a regression
5069 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005070
Georg Brandl278fc502008-07-19 12:46:12 +00005071- Issue #2862: Make int and float freelist management consistent with
5072 other freelists. Changes their CompactFreeList apis into
5073 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005074

Thomas Heller57adf222008-08-14 19:10:48 +00005078- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5079 api functions without holding the GIL, which could lead to a fatal
5080 error when they failed.
5081
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005082- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5091 ForkingPickler.register() to resolve conflict with ctypes.
5092
Vinay Sajip51e65192008-07-18 09:01:10 +00005093- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

5096 a valid dlerror() message.
5097
Thomas Heller2bad6572008-07-15 17:19:50 +00005098- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5099 incomplete structure was created.

5518 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005519 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005520
5521 This is controlled by the configure argument ``--with-universal-archs``:
5522
5523 - ``--with-universal-archs=all``: install 4-way universal
5524
5525 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5526
5527 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5528
5529 This option should be used in combination with ``--enable-universalsdk=``.
5530
5531 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

5568 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005569
Christian Heimese74c8f22008-04-19 02:23:57 +00005570- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5571
Georg Brandl3ee81df2008-05-17 18:14:43 +00005572- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
5573 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00005574
Georg Brandl3ee81df2008-05-17 18:14:43 +00005575- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00005581- Issue #1631171: Re-implement the 'warnings' module in C (the
5582 original Python code has been kept as backup). This will allow for
5583 using the 'warning's machinery in such places as the parser where
5584 use of pure Python code is not possible. Both the ``showarning()``
5585 and ``formatwarning()`` gain an optional 'line' argument which is
5586 not called by default for backwards-compatibility reasons. Setting
5587 ``warnings.showwarning()`` to an implementation that lacks support
5588 for the ``line`` argument will raise a DeprecationWarning.

Thomas Hellerbf027c42008-04-24 18:14:19 +00005611 reference to themselves.
5612
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005613- The getpass module has been improved on Unix. It now uses /dev/tty
5614 by default and uses stderr instead of stdout. A GetPassWarning is
5615 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00005616

Georg Brandl3ee81df2008-05-17 18:14:43 +00005630- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005631 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005651- Issue #2550: The approach used by client/server code for obtaining
5652 ports to listen on in network-oriented tests has been refined in an
5653 effort to facilitate running multiple instances of the entire
5654 regression test suite in parallel without issue.
5655 test_support.bind_port() has been fixed such that it will always
5656 return a unique port -- which wasn't always the case with the
5657 previous implementation, especially if socket options had been set
5658 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5659 new implementation of bind_port() will actually raise an exception
5660 if it is passed an AF_INET/SOCK_STREAM socket with either the
5661 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5662 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5663 the socket it's been passed. This currently only applies to
5664 Windows. This option prevents any other sockets from binding to the
5665 host/port we've bound to, thus removing the possibility of the
5666 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5667 when a second SOCK_STREAM socket binds and accepts to a host/port
5668 that's already been bound by another socket. The optional preferred
5669 port parameter to bind_port() has been removed. Under no
5670 circumstances should tests be hard coding ports!
5671
5672 test_support.find_unused_port() has also been introduced, which will
5673 pass a temporary socket object to bind_port() in order to obtain an
5674 unused port. The temporary socket object is then closed and
5675 deleted, and the port is returned. This method should only be used
5676 for obtaining an unused port in order to pass to an external program
5677 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5678 a parameter to a server-oriented class that doesn't give you direct
5679 access to the underlying socket used.
5680
5681 Finally, test_support.HOST has been introduced, which should be used
5682 for the host argument of any relevant socket calls (i.e. bind and
5683 connect).

5959
Fred Drakea8ee94b2008-03-01 02:45:07 +00005960- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005961 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005962
Georg Brandlad61bc82008-02-23 15:11:18 +00005963- Issue #2067: file.__exit__() now calls subclasses' close() method.
5964
5965- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005966
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005967- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005968 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005969
Eric Smitha73fbe72008-02-23 03:09:44 +00005970- Added the future_builtins module, which contains hex() and oct().
5971 These are the PEP 3127 version of these functions, designed to be
5972 compatible with the hex() and oct() builtins from Python 3.0. They
5973 differ slightly in their output formats from the existing, unchanged
5974 Python 2.6 builtins. The expected usage of the future_builtins
5975 module is:
5976 from future_builtins import hex, oct
5977
Eric Smith7ef40bf2008-02-20 23:34:22 +00005978- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5979 exponents for exponents with absolute value < 100. Follows C99
5980 standard. This is a change on Windows, which would use 3 digits.
5981 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5982 so that any alterations it does to the resulting string will be
5983 available in stringlib/formatter.h (for float.__format__).
5984
Eric Smith5a3c1352008-02-19 13:21:56 +00005985- Implemented PEP 3101, Advanced String Formatting. This adds a new
5986 builtin format(); a format() method for str and unicode; a
5987 __format__() method to object, str, unicode, int, long, float, and
5988 datetime; the class string.Formatter; and the C API
5989 PyObject_Format().
5990
Georg Brandl3ee81df2008-05-17 18:14:43 +00005991- Fixed several potential crashes, all caused by specially crafted
5992 __del__ methods exploiting objects in temporarily inconsistent
5993 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005994
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005995- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005996 prevent a possible crash: an Abstract Base Class would try to access
5997 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005998
Georg Brandl3ee81df2008-05-17 18:14:43 +00005999- Fixed repr() and str() of complex numbers with infinity or nan as
6000 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006001
Georg Brandl3ee81df2008-05-17 18:14:43 +00006002- Clear all free lists during a gc.collect() of the highest generation
6003 in order to allow pymalloc to free more arenas. Python may give back
6004 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006005
Georg Brandl3ee81df2008-05-17 18:14:43 +00006006- Issue #2045: Fix an infinite recursion triggered when printing a
6007 subclass of collections.defaultdict, if its default_factory is set
6008 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006009
Christian Heimesf75dbef2008-02-08 00:11:31 +00006010- Fixed a minor memory leak in dictobject.c. The content of the free
6011 list was not freed on interpreter shutdown.
6012
Georg Brandl21e99f42010-03-07 15:23:59 +00006013- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006014 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006015
Georg Brandl3ee81df2008-05-17 18:14:43 +00006016- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6017 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006018 to compact the internal free lists of pre-allocted ints and floats.
6019
Georg Brandl3ee81df2008-05-17 18:14:43 +00006020- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6021 calls. Python expected the return type int but the fork familie
6022 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006023
Georg Brandl3ee81df2008-05-17 18:14:43 +00006024- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6025 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006026
Georg Brandl3ee81df2008-05-17 18:14:43 +00006027- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6028 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006029
Georg Brandl3ee81df2008-05-17 18:14:43 +00006030- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6031 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006032
Georg Brandl3ee81df2008-05-17 18:14:43 +00006033- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6034 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006035
Georg Brandl3ee81df2008-05-17 18:14:43 +00006036- Patch #1473257: generator objects gain a gi_code attribute. This is
6037 the same object as the func_code attribute of the function that
6038 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006039
Georg Brandl3ee81df2008-05-17 18:14:43 +00006040- Issue #1920: "while 0" statements were completely removed by the
6041 compiler, even in the presence of an "else" clause, which is
6042 supposed to be run when the condition is false. Now the compiler
6043 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006044
Guido van Rossumeead05f2008-01-24 18:21:02 +00006045- A few crashers fixed: weakref_in_del.py (issue #1377858);
6046 loosing_dict_ref.py (issue #1303614, test67.py);
6047 borrowed_ref_[34].py (not in tracker).
6048
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006049- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006050 suppressed while an extension is loaded by calling SetErrorMode in
6051 dynload_win.c. The error is still reported properly.
6052
Georg Brandl3ee81df2008-05-17 18:14:43 +00006053- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006054 several extension methods and modules do not work without unicode
6055 support.
6056
Georg Brandl26543b12008-01-21 18:36:51 +00006057- Issue #1882: when compiling code from a string, encoding cookies in the
6058 second line of code were not always recognized correctly.
6059
Georg Brandl14404b62008-01-19 19:27:05 +00006060- Issue #1679: "0x" was taken as a valid integer literal.
6061
Georg Brandl6caad7d2008-01-26 14:19:22 +00006062- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006063 added.
6064
Christian Heimesc94e2b52008-01-14 04:13:37 +00006065- sys.float_info / PyFloat_GetInfo: The floating point information
6066 object was converted from a dict to a specialized structseq object.
6067
Georg Brandl3ee81df2008-05-17 18:14:43 +00006068- Patch #1816: Added sys.flags structseq. It exposes the status of
6069 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006070
Georg Brandl3ee81df2008-05-17 18:14:43 +00006071- Objects/structseq.c: Implemented new structseq representation. The
6072 patch makes structseqs (e.g. the return value of os.stat) more
6073 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006074
Georg Brandl3ee81df2008-05-17 18:14:43 +00006075- Patch #1700288: added a type attribute cache that caches method
6076 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006077
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006078- Bug #1776: __import__() no longer accepts filenames on any platform.
6079 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006080

6082
Georg Brandl3ee81df2008-05-17 18:14:43 +00006083- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6084 envvar and sys.dont_write_bytecode attribute. All these can be set
6085 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006086
Georg Brandl3ee81df2008-05-17 18:14:43 +00006087- Improve some exception messages when Windows fails to load an
6088 extension module. Now we get for example '%1 is not a valid Win32
6089 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006090
Georg Brandl3ee81df2008-05-17 18:14:43 +00006091- Bug #1481296: Fixed long(float('nan')) != 0L.

6094 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006095
Christian Heimes0a8143f2007-12-18 23:22:54 +00006096- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006097 and INF. float("nan"), float("inf") and float("-inf") now work on
6098 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006099
Georg Brandl3ee81df2008-05-17 18:14:43 +00006100- Compiler now generates simpler and faster code for dictionary
6101 literals. The oparg for BUILD_MAP now indicates an estimated
6102 dictionary size. There is a new opcode, STORE_MAP, for adding
6103 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006137- Issue #1265: Fix a problem with sys.settrace, if the tracing
6138 function uses a generator expression when at the same time the
6139 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006140
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006141- sets and frozensets now have an isdisjoint() method.

6146
Georg Brandl21e99f42010-03-07 15:23:59 +00006147- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006148 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6149 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006150
Georg Brandl3ee81df2008-05-17 18:14:43 +00006151- Issue #1686386: Tuple's tp_repr did not take into account the
6152 possibility of having a self-referential tuple, which is possible
6153 from C code. Nor did object's tp_str consider that a type's tp_str
6154 could do something that could lead to an inifinite recursion.
6155 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6156 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006157
Georg Brandl3ee81df2008-05-17 18:14:43 +00006158- Issue #1164: It was possible to trigger deadlock when using the
6159 'print' statement to write to a file since the GIL was not released
6160 as needed. Now PyObject_Print() does the right thing along with
6161 various tp_print implementations of the built-in types and those in
6162 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006164- Issue #1147: Exceptions were directly allowing string exceptions in
6165 their throw() method even though string exceptions no longer
6166 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006168- Issue #1096: Prevent a segfault from getting the repr of a very
6169 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00006171- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006172 PyObject_Call() never calling back out to Python code to trigger
6173 recursion depth updates/checks. Required the creation of a static
6174 RuntimeError instance in case normalizing an exception put the
6175 recursion check value past its limit. Fixes crashers
6176 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006191- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006192 __*__ attributes. (Some already existed, e.g., __doc__ and
6193 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006194
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006195- Add -3 option to the interpreter to warn about features that are

6197
Georg Brandl2134e752007-05-21 20:34:16 +00006198- Patch #1686487: you can now pass any mapping after '**' in function
6199 calls.
6200
Collin Winter62903052007-05-18 23:11:24 +00006201- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006202 "except E as target:". This is to provide forwards compatibility
6203 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006204
Brett Cannon229cee22007-05-05 01:34:02 +00006205- Deprecate BaseException.message as per PEP 352.
6206
Georg Brandl3ee81df2008-05-17 18:14:43 +00006207- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006208 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006210- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006211 setting a plain string, ie don't expand to single letter identifiers.
6212
Raymond Hettinger13936692007-04-11 18:40:58 +00006213- Request #1191699: Slices can now be pickled.
6214
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006215- Request #1193128: str.translate() now allows a None argument for
6216 translations that only remove characters without re-mapping the
6217 remaining characters.
6218
Georg Brandl5cb76c12007-03-21 09:00:39 +00006219- Patch #1682205: a TypeError while unpacking an iterable is no longer
6220 masked by a generic one with the message "unpack non-sequence".
6221
Neal Norwitzaa754b72007-03-21 06:39:48 +00006222- Remove unused file Python/fmod.c.
6223
Guido van Rossum143b5642007-03-23 04:58:42 +00006224- Bug #1683368: The object.__init__() and object.__new__() methods are
6225 now stricter in rejecting excess arguments. The only time when
6226 either allows excess arguments is when it is not overridden and the
6227 other one is. For backwards compatibility, when both are
6228 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006229 warning later). Also, type.__init__() insists on the same signature
6230 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006231
Georg Brandl3ee81df2008-05-17 18:14:43 +00006232- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6233 object to complex using its __complex__() method before falling back
6234 to the __float__() method. Therefore, the functions in the cmath
6235 module now can operate on objects that define a __complex__()
6236 method.

6247 its type.

6253
Georg Brandl7b9c5552007-03-12 14:30:05 +00006254- Bug #1678647: write a newline after printing an exception in any
6255 case, even when converting the value to a string failed.
6256
Georg Brandl871f1bc2007-03-12 13:17:36 +00006257- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006258 its argument, if it exists. If not, it will work like before. This
6259 allows customizing the output of dir() in the presence of a
6260 __getattr__().

6269 parthensized forms. This means complex(repr(x)) now works instead of
6270 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006271
Georg Brandlaa2321b2007-03-07 00:40:28 +00006272- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006273 makes the filenames the warning module prints much more sensible
6274 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006275

6277 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006278 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00006287- Patch #1674228: when assigning a slice (old-style), check for the
6288 sq_ass_slice instead of the sq_slice slot.
6289
Georg Brandl3ee81df2008-05-17 18:14:43 +00006290- When printing an unraisable error, don't print exceptions. before

6901 Python would crash instead of raising an error.
6902
Thomas Hellerc2f77252007-03-09 19:21:28 +00006903- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)

6918 accepted in TestSuite.addTest(). This should cause no
6919 incompatibility since it never made sense with ordinary subclasses
6920 -- the failure just occurred later, with a more cumbersome
6921 exception.

7204 obtained from the TLS negotiation itself. Patch contributed by Bill
7205 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007206
Georg Brandl3ee81df2008-05-17 18:14:43 +00007207- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007208 that the SMTP.starttls() caller no longer needs to call ehlo()
7209 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210 does not claim to support starttls. Adds the
7211 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7292 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7293 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007310 time so that opening a database previously created with the DB_DUP
7311 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7312 opens. Specifically: dictionary assignment to a DB object will
7313 replace all values for a given key when the database allows
7314 duplicate values. DB users should use DB.put(k, v) when they want
7315 to store duplicates; not DB[k] = v.

7322 characters with ASCII value less than 32. Also, it correctly quotes
7323 dots only if they occur on a single line, as opposed to the previous
7324 behavior of quoting dots if they are the second character of any
7325 line.

7648-----
7649
Georg Brandl3ee81df2008-05-17 18:14:43 +00007650- Unified naming convention for free lists and their limits. All free
7651 lists in Object/ are named ``free_list``, the counter ``numfree``
7652 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7653 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007654
Georg Brandl3ee81df2008-05-17 18:14:43 +00007655- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7656 to ``PyTuple_SetItem``, it can be used to populate a brand new
7657 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007658
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007659- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007661- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7662 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7663 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007664
7665- Patch #1720595: add T_BOOL to the range of structmember types.
7666
7667- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7668 ``PyFloat_GetInfo()`` to the float API.
7669
Georg Brandl3ee81df2008-05-17 18:14:43 +00007670- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7671 of w# format code incorrectly truncated the length to an int, even
7672 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7673 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007674
Georg Brandl3ee81df2008-05-17 18:14:43 +00007675- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7676 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007677
Georg Brandl3ee81df2008-05-17 18:14:43 +00007678- PEP 3123: Provide forward compatibility with Python 3.0, while
7679 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7680 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007681
Georg Brandl3ee81df2008-05-17 18:14:43 +00007682- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7683 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007684
7685- Patch #1733960: Allow T_LONGLONG to accept ints.
7686
7687- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7688

7692
7693- Fix some leftovers from the conversion from int to Py_ssize_t
7694 (relevant to strings and sequences of more than 2**31 items).
7695
7696- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7697 outside of pystate.c and should not be necessary.
7698
Georg Brandl3ee81df2008-05-17 18:14:43 +00007699- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7700 absolute imports. In earlier versions they might have used relative
7701 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007702
Georg Brandl3ee81df2008-05-17 18:14:43 +00007703- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7704 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007705
Georg Brandl3ee81df2008-05-17 18:14:43 +00007706- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7707 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007713- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7714 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7715 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7716 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007717
Georg Brandl3ee81df2008-05-17 18:14:43 +00007718- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00007731- Removed the macfs module. It had been deprecated since Python 2.5.
7732 This lead to the deprecation of macostools.touched() as it relied
7733 solely on macfs and was a no-op under OS X.
