Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000287 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
288 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
289 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

309Core and Builtins
310-----------------
311
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000312- Issue #7301: Add environment variable $PYTHONWARNINGS.
313
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000314- Issue #8329: Don't return the same lists from select.select when no fds are
315 changed.
316
Georg Brandlfee0f442010-05-22 21:26:21 +0000317- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000318 on 64-bit machines. The shift count for either left or right shift is
319 permitted to be up to sys.maxsize.
320
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000321- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000325- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
326
Georg Brandlfee0f442010-05-22 21:26:21 +0000327- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
328 with a non-empty format string. This is an effort to future-proof user
329 code. If a derived class does not currently implement __format__ but later
330 adds its own __format__, it would most likely break user code that had
331 supplied a format string. This will be changed to a DeprecationWaring in
332 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000333
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000334- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000359- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000360 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
361 `ssl.OPENSSL_VERSION_NUMBER`.

364
Georg Brandlfee0f442010-05-22 21:26:21 +0000365- Issue #8257: The Decimal construct now accepts a float instance directly,
366 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000367
368 >>> Decimal(1.1)
369 Decimal('1.100000000000000088817841970012523233890533447265625')
370
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000371- collections.Counter() now supports a subtract() method.
372
Georg Brandlfee0f442010-05-22 21:26:21 +0000373- The functools module now has a total_ordering() class decorator to simplify
374 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000375
Georg Brandlfee0f442010-05-22 21:26:21 +0000376- The functools module also adds cmp_to_key() as a tool to transition old-style
377 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000378
Georg Brandlfee0f442010-05-22 21:26:21 +0000379- Issue #8294: The Fraction constructor now accepts Decimal and float instances
380 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000381
Georg Brandlfee0f442010-05-22 21:26:21 +0000382- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
383 InvalidOperation instead of returning False. (Comparisons involving a quiet
384 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
385 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000386
Georg Brandlfee0f442010-05-22 21:26:21 +0000387- Issue #2531: Comparison operations between floats and Decimal instances now
388 return a result based on the numeric values of the operands; previously they
389 returned an arbitrary result based on the relative ordering of id(float) and
390 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000391
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000392- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000393 argument `-` which tells it to read files to compile from stdin. Each line is
394 read on demand and the named file is compiled immediately. (Original patch by
395 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000396
Georg Brandlfee0f442010-05-22 21:26:21 +0000397- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000400- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
401 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000402 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +0000404- Comparisons using one of <, <=, >, >= between a complex instance and a
405 Fractions instance now raise TypeError instead of returning True/False. This
406 makes Fraction <=> complex comparisons consistent with int <=> complex, float
407 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000408

417
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000418- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000419 didn't support chflags() (for example ZFS under FreeBSD). The error is now
420 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000421
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000422- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000462- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000463 for ``TimedRotatingFileHandler`` by using the modification time of an existing
464 log file to compute the next rollover time. If the log file does not exist,
465 the current time is used as the basis for the computation.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000506- Issue #8300: When passing a non-integer argument to struct.pack with any
507 integer format code, struct.pack first attempts to convert the non-integer
508 using its __index__ method. If that method is non-existent or raises
509 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +0000511- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
512 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
513 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +0000514 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
515 inconsistent: __int__ was used for some integer codes but not for others, and
516 the set of integer codes for which it was used differed between native packing
517 and standard packing.)

742 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000743 library would return a bogus result; on Solaris, it was possible to crash the
744 interpreter. Patch by Stefan Krah.

755 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +0000756
Georg Brandlba83f822010-03-14 09:50:54 +0000757- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
758 and add the additional members returned in an OSVERSIONINFOEX structure. The
759 new members are service_pack_major, service_pack_minor, suite_mask, and
760 product_type.
Eric Smithee931b72010-01-27 00:28:29 +0000761
Georg Brandlba83f822010-03-14 09:50:54 +0000762- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
763 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
764 returning NULL. The macro now returns a statically allocated empty string
765 instead.

772 including:
Mark Dickinson8efef5c2010-01-12 22:23:56 +0000773
Georg Brandlba83f822010-03-14 09:50:54 +0000774 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
775 strings,
776 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
777 numeric strings corresponding to subnormal values,
778 (3) a memory leak for some values large enough to cause overflow, and
779 (4) a number of flaws that could lead to incorrectly rounded results.
780
781- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
782 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +0000783

794 interpreter shutdown.
795
Georg Brandlba83f822010-03-14 09:50:54 +0000796- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
797 XML processing instructions and comments. These raw characters are allowed
798 by the XML specification, and are necessary when outputting e.g. PHP code in
799 a processing instruction. Patch by Neil Muller.
Antoine Pitrou42fb6ab2010-02-09 17:08:05 +0000800

Vinay Sajip0e6e97d2010-02-04 20:23:45 +0000806
Antoine Pitroud840e512010-02-04 20:20:18 +0000807- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000808 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000809 Also, raise ValueError rather than TypeError when an unknown TIPC address
810 type is specified. Patch by Brian Curtin.
811
Vinay Sajip28c382f2010-02-04 18:48:53 +0000812- logging: Implemented PEP 391.
813
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000814- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000815 file position when calling `truncate()`. It would previously change the file
816 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000817 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
818
Benjamin Petersone06f7112010-01-28 02:15:02 +0000819- UserDict is now a new-style class.
820
Georg Brandlba83f822010-03-14 09:50:54 +0000821- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
822 class used to represent files stored inside an archive. The new
823 implementation is significantly faster and can be wrapped in a
824 ``io.BufferedReader`` object for more speedups. It also solves an issue
825 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
826 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +0000827
Benjamin Peterson2deb5c72010-01-27 02:16:42 +0000828- Issue #7792: Registering non-classes to ABCs raised an obscure error.
829
Georg Brandlba83f822010-03-14 09:50:54 +0000830- Removed the deprecated functions ``verify()`` and ``vereq()`` from
831 Lib/test/test_support.py.

Georg Brandlba83f822010-03-14 09:50:54 +0000833- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
834 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000835
Georg Brandlba83f822010-03-14 09:50:54 +0000836- Issue #7748: Since unicode values are supported for some metadata options in
837 Distutils, the DistributionMetadata get_* methods will now return an utf-8
838 encoded string for them. This ensures that the upload and register commands
839 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000840
Georg Brandlba83f822010-03-14 09:50:54 +0000841- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000842 headers in multipart/signed MIME parts, which fixes one of the sources of
843 invalid modifications to such parts by Generator.
844
Georg Brandlba83f822010-03-14 09:50:54 +0000845- Issue #7701: Fix crash in ``binascii.b2a_uu()`` in debug mode when given a

913Core and Builtins
914-----------------
915
Georg Brandlba83f822010-03-14 09:50:54 +0000916- The ``__complex__()`` method is now looked up on the class of instances to
917 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000918
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000919- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
920 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
921
Mark Dickinson1b34d252010-01-01 17:27:30 +0000922- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000923 DeprecationWarning when passed a float argument where an integer was expected.
924 These functions and methods now raise TypeError instead. The majority of the
925 effects of this change are in the extension modules, but some core functions
926 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
927 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000940- Issue #1811: Improve accuracy and cross-platform consistency for true division
941 of integers: the result of a/b is now correctly rounded for ints a and b (at
942 least on IEEE 754 platforms), and in particular does not depend on the
943 internal representation of a long.

951
Georg Brandlba83f822010-03-14 09:50:54 +0000952 These executables now work properly with the arch(1) command: ``arch -ppc
953 python`` will start a universal binary version of python in PPC mode (unlike
954 previous releases).

1094 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001095
Georg Brandlba83f822010-03-14 09:50:54 +00001096- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1097 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001098
Georg Brandlba83f822010-03-14 09:50:54 +00001099- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1100 1e-100 used to raise OverflowError, but now gives the requested 120
1101 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001109
Georg Brandlba83f822010-03-14 09:50:54 +00001110- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1111 decimal string that's guaranteed to round back to x under correct rounding
1112 (with round-half-to-even rounding mode). Previously it gave a string based on
1113 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1114 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1115 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001116
Georg Brandlba83f822010-03-14 09:50:54 +00001117- Issue #7117: On almost all platforms: float-to-string and string-to-float
1118 conversions within Python are now correctly rounded. Places these conversions
1119 occur include: str for floats and complex numbers; the float and complex
1120 constructors; old-style and new-style numeric formatting; serialization and
1121 deserialization of floats and complex numbers using marshal, pickle and json;
1122 parsing of float and imaginary literals in Python code; Decimal-to-float
1123 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001124
Georg Brandlba83f822010-03-14 09:50:54 +00001125 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1126 providing correctly-rounded strtod and dtoa C functions. This code is
1127 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1128 the C compiler. There may be a small number of platforms on which correct
1129 operation of this code cannot be guaranteed, so the code is not used: notably,
1130 this applies to platforms where the C double format is not IEEE 754 binary64,
1131 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1132 and Python's configure script is unable to determine how to change the FPU
1133 precision. On these platforms conversions use the platform strtod and dtoa,
1134 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001135
Georg Brandlba83f822010-03-14 09:50:54 +00001136- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1137 uses the correctly-rounded string <-> float conversions described above (when
1138 available), and so produces correctly rounded results that will display nicely
1139 under the float repr. There are two related small changes: (1) round now
1140 accepts any class with an ``__index__()`` method for its second argument (but
1141 no longer accepts floats for the second argument), and (2) an excessively
1142 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1143 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001147- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001285
Georg Brandlba83f822010-03-14 09:50:54 +00001286 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1287 (2) parsing of strings representing infinities and nans was locale aware; and
1288 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00001289
Georg Brandlba83f822010-03-14 09:50:54 +00001290- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1291 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1292 but with at least one decimal point and with a default precision
1293 of 12. Previously, the behavior the same but with a default precision of 6.
1294 This more closely matches ``str()``, and reduces surprises when adding
1295 alignment flags to the empty presentation type. This also affects the new
1296 complex.__format__ in the same way.
1297
1298- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1299 classtype's, even if it was None. property now inserts the __doc__ into the
1300 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00001361 untrackable objects are not tracked by the garbage collector. This can reduce

1370 internal representation of integers, for performance reasons. Base 2**30 is
1371 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl6425a2f2008-12-28 11:54:53 +00001459- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001460 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001461
Skip Montanarof205c132008-12-23 03:30:15 +00001462- Added test case to ensure attempts to read from a file opened for writing
1463 fail.
1464
Georg Brandlba83f822010-03-14 09:50:54 +00001465- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print

Georg Brandlba83f822010-03-14 09:50:54 +00001479- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1480 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1481 instances. On a typical machine this saves 3 bytes of memory (on average) per
1482 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001484- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1485 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1486 instead of throwing a MemoryError.
1487
Georg Brandlba83f822010-03-14 09:50:54 +00001488- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00001491- Issue #4367: Python would segfault during compiling when the unicodedata

1493
Georg Brandlba83f822010-03-14 09:50:54 +00001494- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1495 file objects with closefd=False. The file descriptor is still kept open but
1496 the file object behaves like a closed file. The ``FileIO`` object also got a
1497 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001499- Issue #4348: Some bytearray methods returned that didn't cause any change to
1500 the bytearray, returned the same bytearray instead of a copy.
1501
Georg Brandlba83f822010-03-14 09:50:54 +00001502- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00001514- Issue #4209: Enabling unicode_literals and the print_function in the same
1515 __future__ import didn't work.
1516
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001517- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001518 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001519
Georg Brandlba83f822010-03-14 09:50:54 +00001520- On windows, ``os.chdir()`` given unicode was not working if
1521 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1522 this code path is really executed because I cannot move to such directory on
1523 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001524
Georg Brandlba83f822010-03-14 09:50:54 +00001525- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1526 element is temporarily replaced with an equivalent frozenset. But the
1527 eventual KeyError would always report the empty ``frozenset()`` as the missing
1528 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001545- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1546 returned them on 64bit platforms.
1547
Walter Dörwalded960ac2009-05-03 22:36:33 +00001548- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1549 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1550 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1551 of using the replace error handler in PyUnicode_DecodeUTF8().
1552
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001553- Issue #3739: The unicode-internal encoder now reports the number of characters
1554 consumed like any other encoder (instead of the number of bytes).
1555
Georg Brandlba83f822010-03-14 09:50:54 +00001556- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1557 allocator will be automatically disabled when running under Valgrind. This
1558 gives improved memory leak detection when running under Valgrind, while taking
1559 advantage of pymalloc at other times.

2925
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002926- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2927 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2928 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2929 ``printf`` function, whereas PyString_FromFormat has an independent
2930 implementation and uses "%zd" on all platforms for size_t values.
2931 This makes a difference on win64, where ``printf`` needs "%Id" to display
2932 64bit values.

2938 object; previously an int would be returned for small values. the __long__
2939 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00002948 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002949 was correctly parsed but parsing of subsequent arguments failed.
2950
Vinay Sajip35e3b032008-09-01 14:33:59 +00002951- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002952 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2953 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2954 when given a tuple of classes as second argument, were looking up
2955 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2956 type object.
2957
Neal Norwitz18aa3882008-08-24 05:04:52 +00002958- Fix crashes on memory allocation failure found with failmalloc.

3101-----------------
3102
Guido van Rossumf8402962008-08-20 15:01:50 +00003103- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3104 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3105 extensions do not automatically benefit from the class attribute
3106 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3107 to their tp_flags field if they care. This is a backwards
3108 compatibility feature; in 3.0, all types will use the cache by
3109 default.
3110
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003111- Keyword arguments can now follow starred arguments. (``f(a, *args,

Thomas Heller0ad5ae02008-08-19 19:25:04 +00003114- ctypes function pointers that are COM methods have a boolean True
3115 value again.
3116
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003117- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3118 by denying s# to parse objects that have a releasebuffer procedure,
3119 and introducing s*.
3120
Georg Brandl1e13ea92008-08-11 09:07:59 +00003121- Issue #3537: Fix an assertion failure when an empty but presized dict
3122 object was stored in the freelist.
3123
Mark Dickinsonb6467572008-08-04 21:30:09 +00003124- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3125 ValueError consistently across platforms.
3126
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003127- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3128 (64bit Unix, for example), unichr() would truncate its argument and return
3129 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3130
Neal Norwitze7d8be82008-07-31 17:17:14 +00003131- Apply security patches from Apple.
3132
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003133- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3134 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3135
Antoine Pitrou92f82162008-07-25 22:22:08 +00003136- Issue #1819: function calls with several named parameters are now on
3137 average 35% faster (as measured by pybench).
3138
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003139- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3140 the python debugger steps into a class statement: the free variables (local
3141 variables defined in an outer scope) would be deleted from the outer scope.
3142
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003143- Issue #2620: Overflow checking when allocating or reallocating memory
3144 was not always being done properly in some python types and extension
3145 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3146 all been updated to perform better checks and places in the code that
3147 would previously leak memory on the error path when such an allocation
3148 failed have been fixed.

3157
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003158- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3159 version reported by these tools does not necessarily follow the python
3160 version numbering scheme, so the module is less strict when parsing it.
3161
Nick Coghlanf70385a2008-08-18 12:42:46 +00003162- Issue #2235: Added Py3k warnings for types which will become unhashable
3163 under the stricter __hash__ inheritance rules in 3.0. Several types
3164 which did not meet the rules for hash invariants and were already
3165 unhashable in 3.0 have now been explicitly flagged as unhashable in
3166 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3167 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3168
Brett Cannon88f801d2008-08-18 00:46:22 +00003169- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003178- Issue #3575: Incremental decoder's decode function now takes bytearray
3179 by using 's*' instead of 't#'.
3180

3191 after a 302 response in the case of not going through a proxy.
3192
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003193- Issue #2676: in the email package, content-type parsing was hanging on
3194 pathological input because of quadratic or exponential behaviour of a
3195 regular expression.
3196
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003197- Issue #3476: binary buffered reading through the new "io" library is now
3198 thread-safe.
3199
Brett Cannonbf3157b2008-08-14 05:00:03 +00003200- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3201 since mimetools itself is deprecated. Because modules are cached, all
3202 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3203
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003204- Issue #3134: shutil referenced undefined WindowsError symbol.

Brett Cannon83e81842008-08-09 23:30:55 +00003209- Copied the implementation of reduce() to _functools.reduce() to have a
3210 version that did not raise a DeprecationWarning under -3.
3211
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003212- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3213 a MemoryError rather than silently stop the iteration.
3214
Guido van Rossum59ce9012008-08-09 14:55:34 +00003215- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3216 to _sre.compile() will now be rejected. This should not affect anybody
3217 since the re.compile() function never generates invalid re-bytecode.
3218
Skip Montanaroa032bf42008-08-08 22:52:51 +00003219- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3220 upon first access it can be automatically initialized from the csv file if
3221 it wasn't initialized during instantiation.
3222
Brett Cannon3aa2a492008-08-06 22:28:09 +00003223- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3224 the reload() built-in has been removed.
3225
Brett Cannon7e30b672008-08-04 21:52:25 +00003226- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003227 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3235 raised an AttributeError.
3236
Benjamin Peterson01a24322008-07-28 23:35:27 +00003237- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003238 asking for a specific length. This problem only affected files opened
3239 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003240

3263
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003264- Issue #3394: zipfile.writestr sets external attributes when passed a
3265 file name rather than a ZipInfo instance, so files are extracted with
3266 mode 0600 rather than 000 under Unix.
3267
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003268- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3269 argument in python 2.5, this broke code that subclassed Popen to include its
3270 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003280- Issue #2235: the C API function PyObject_HashNotImplemented and its
3281 interaction with the tp_hash slot (added in 2.6b2) are now documented
3282
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003283- Issue #643841: The language reference now provides more detailed
3284 coverage of the lookup process for special methods. The disclaimers
3285 regarding lack of coverage of new-style classes have also been
3286 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003294Core and Builtins
3295-----------------
3296
Georg Brandl3e483f62008-07-16 22:57:41 +00003297- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3298 its methods now allow for items objects that can be converted to
3299 an integer using operator.index().
3300
Mark Dickinson64b7e502008-07-16 09:40:03 +00003301- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3302 produced a ValueError instead of giving the correct float.
3303
Eric Smitha5fa5a22008-07-16 00:11:49 +00003304- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3305 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3306
Mark Dickinson7103aa42008-07-15 19:08:33 +00003307- Issue #3008: the float type has a new instance method 'float.hex'
3308 and a new class method 'float.fromhex' to convert floating-point
3309 numbers to and from hexadecimal strings, respectively.
3310
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003311- Issue #2235: __hash__ is once again inherited by default. To allow
3312 collections.Hashable to remain meaningful in the presence of the
3313 default hash implementation (object.__hash__), it is now possible
3314 to explicit block inheritance of hash by setting __hash__=None at
3315 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3316 level.
3317
Nick Coghlanb028f502008-07-13 14:52:36 +00003318- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3319 the parent module cannot be found while performing an absolute import.
3320 This means that an incorrectly defined __package__ attribute will
3321 now only prevent relative imports in that module rather than causing
3322 all imports from that module to fail.
3323
Nick Coghlan14ff9942008-07-08 14:21:42 +00003324- Issue #2517: Allow unicode messages in Exceptions again by correctly
3325 bypassing the instance dictionary when looking up __unicode__ on
3326 new-style classes.
3327
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003328- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3329 set to a custom object whose write() method happens to install
3330 another file in sys.stdout.
3331
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003332- Issue #3088: Corrected a race condition in classes derived from
3333 threading.local: the first member set by a thread could be saved in
3334 another thread's dictionary.
3335
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003336- Issue #3004: Minor change to slice.indices(): the start and stop
3337 arguments are now treated identically, making the behaviour easier
3338 to describe and understand. For example, slice(None, -10,
3339 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3340 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3341 10, -1).
3342
Georg Brandl278fc502008-07-19 12:46:12 +00003343- Issue #3219: Calling a function with repeated keyword arguments,
3344 f(a=2, a=23), would not cause a syntax error. This was a regression
3345 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003346
Georg Brandl278fc502008-07-19 12:46:12 +00003347- Issue #2862: Make int and float freelist management consistent with
3348 other freelists. Changes their CompactFreeList apis into
3349 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003350

3352-------
3353
Thomas Heller57adf222008-08-14 19:10:48 +00003354- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3355 api functions without holding the GIL, which could lead to a fatal
3356 error when they failed.
3357
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003358- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3367 ForkingPickler.register() to resolve conflict with ctypes.
3368
Vinay Sajip51e65192008-07-18 09:01:10 +00003369- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

3372 a valid dlerror() message.
3373
Thomas Heller2bad6572008-07-15 17:19:50 +00003374- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3375 incomplete structure was created.
3376
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003377- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00003379- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3380
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003381- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003382
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003383- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3384 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003385 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003386 content-length. The problem had been corrected in the 2.4 branch, but never
3387 merged into trunk.
3388
Georg Brandle78fbcc2008-07-05 10:13:36 +00003389- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00003397 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00003398

Georg Brandl5cc774e2008-06-11 20:28:06 +00003795 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003796
3797 This is controlled by the configure argument ``--with-universal-archs``:
3798
3799 - ``--with-universal-archs=all``: install 4-way universal
3800
3801 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3802
3803 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3804
3805 This option should be used in combination with ``--enable-universalsdk=``.
3806
3807 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003857- Issue #1631171: Re-implement the 'warnings' module in C (the
3858 original Python code has been kept as backup). This will allow for
3859 using the 'warning's machinery in such places as the parser where
3860 use of pure Python code is not possible. Both the ``showarning()``
3861 and ``formatwarning()`` gain an optional 'line' argument which is
3862 not called by default for backwards-compatibility reasons. Setting
3863 ``warnings.showwarning()`` to an implementation that lacks support
3864 for the ``line`` argument will raise a DeprecationWarning.

3888
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003889- The getpass module has been improved on Unix. It now uses /dev/tty
3890 by default and uses stderr instead of stdout. A GetPassWarning is
3891 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003906- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003907 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003927- Issue #2550: The approach used by client/server code for obtaining
3928 ports to listen on in network-oriented tests has been refined in an
3929 effort to facilitate running multiple instances of the entire
3930 regression test suite in parallel without issue.
3931 test_support.bind_port() has been fixed such that it will always
3932 return a unique port -- which wasn't always the case with the
3933 previous implementation, especially if socket options had been set
3934 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3935 new implementation of bind_port() will actually raise an exception
3936 if it is passed an AF_INET/SOCK_STREAM socket with either the
3937 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3938 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3939 the socket it's been passed. This currently only applies to
3940 Windows. This option prevents any other sockets from binding to the
3941 host/port we've bound to, thus removing the possibility of the
3942 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3943 when a second SOCK_STREAM socket binds and accepts to a host/port
3944 that's already been bound by another socket. The optional preferred
3945 port parameter to bind_port() has been removed. Under no
3946 circumstances should tests be hard coding ports!
3947
3948 test_support.find_unused_port() has also been introduced, which will
3949 pass a temporary socket object to bind_port() in order to obtain an
3950 unused port. The temporary socket object is then closed and
3951 deleted, and the port is returned. This method should only be used
3952 for obtaining an unused port in order to pass to an external program
3953 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3954 a parameter to a server-oriented class that doesn't give you direct
3955 access to the underlying socket used.
3956
3957 Finally, test_support.HOST has been introduced, which should be used
3958 for the host argument of any relevant socket calls (i.e. bind and
3959 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003960

4233Core and builtins
4234-----------------
4235
Fred Drakea8ee94b2008-03-01 02:45:07 +00004236- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004237 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004238
Georg Brandlad61bc82008-02-23 15:11:18 +00004239- Issue #2067: file.__exit__() now calls subclasses' close() method.
4240
4241- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004242
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004243- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004244 issue 215555 for a discussion.
4245
Eric Smitha73fbe72008-02-23 03:09:44 +00004246- Added the future_builtins module, which contains hex() and oct().
4247 These are the PEP 3127 version of these functions, designed to be
4248 compatible with the hex() and oct() builtins from Python 3.0. They
4249 differ slightly in their output formats from the existing, unchanged
4250 Python 2.6 builtins. The expected usage of the future_builtins
4251 module is:
4252 from future_builtins import hex, oct
4253
Eric Smith7ef40bf2008-02-20 23:34:22 +00004254- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4255 exponents for exponents with absolute value < 100. Follows C99
4256 standard. This is a change on Windows, which would use 3 digits.
4257 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4258 so that any alterations it does to the resulting string will be
4259 available in stringlib/formatter.h (for float.__format__).
4260
Eric Smith5a3c1352008-02-19 13:21:56 +00004261- Implemented PEP 3101, Advanced String Formatting. This adds a new
4262 builtin format(); a format() method for str and unicode; a
4263 __format__() method to object, str, unicode, int, long, float, and
4264 datetime; the class string.Formatter; and the C API
4265 PyObject_Format().
4266
Georg Brandl3ee81df2008-05-17 18:14:43 +00004267- Fixed several potential crashes, all caused by specially crafted
4268 __del__ methods exploiting objects in temporarily inconsistent
4269 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004270
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004271- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004272 prevent a possible crash: an Abstract Base Class would try to access
4273 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004274
Georg Brandl3ee81df2008-05-17 18:14:43 +00004275- Fixed repr() and str() of complex numbers with infinity or nan as
4276 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004277
Georg Brandl3ee81df2008-05-17 18:14:43 +00004278- Clear all free lists during a gc.collect() of the highest generation
4279 in order to allow pymalloc to free more arenas. Python may give back
4280 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004281
Georg Brandl3ee81df2008-05-17 18:14:43 +00004282- Issue #2045: Fix an infinite recursion triggered when printing a
4283 subclass of collections.defaultdict, if its default_factory is set
4284 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004285
Christian Heimesf75dbef2008-02-08 00:11:31 +00004286- Fixed a minor memory leak in dictobject.c. The content of the free
4287 list was not freed on interpreter shutdown.
4288
Georg Brandl21e99f42010-03-07 15:23:59 +00004289- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004290 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004291
Georg Brandl3ee81df2008-05-17 18:14:43 +00004292- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4293 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004294 to compact the internal free lists of pre-allocted ints and floats.
4295
Georg Brandl3ee81df2008-05-17 18:14:43 +00004296- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4297 calls. Python expected the return type int but the fork familie
4298 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004299
Georg Brandl3ee81df2008-05-17 18:14:43 +00004300- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4301 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004302
Georg Brandl3ee81df2008-05-17 18:14:43 +00004303- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4304 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004305
Georg Brandl3ee81df2008-05-17 18:14:43 +00004306- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4307 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004308
Georg Brandl3ee81df2008-05-17 18:14:43 +00004309- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4310 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004311
Georg Brandl3ee81df2008-05-17 18:14:43 +00004312- Patch #1473257: generator objects gain a gi_code attribute. This is
4313 the same object as the func_code attribute of the function that
4314 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004315
Georg Brandl3ee81df2008-05-17 18:14:43 +00004316- Issue #1920: "while 0" statements were completely removed by the
4317 compiler, even in the presence of an "else" clause, which is
4318 supposed to be run when the condition is false. Now the compiler
4319 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004320
Guido van Rossumeead05f2008-01-24 18:21:02 +00004321- A few crashers fixed: weakref_in_del.py (issue #1377858);
4322 loosing_dict_ref.py (issue #1303614, test67.py);
4323 borrowed_ref_[34].py (not in tracker).
4324
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004325- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004326 suppressed while an extension is loaded by calling SetErrorMode in
4327 dynload_win.c. The error is still reported properly.
4328
Georg Brandl3ee81df2008-05-17 18:14:43 +00004329- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004330 several extension methods and modules do not work without unicode
4331 support.
4332
Georg Brandl26543b12008-01-21 18:36:51 +00004333- Issue #1882: when compiling code from a string, encoding cookies in the
4334 second line of code were not always recognized correctly.
4335
Georg Brandl14404b62008-01-19 19:27:05 +00004336- Issue #1679: "0x" was taken as a valid integer literal.
4337
Georg Brandl6caad7d2008-01-26 14:19:22 +00004338- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004339 added.
4340
Christian Heimesc94e2b52008-01-14 04:13:37 +00004341- sys.float_info / PyFloat_GetInfo: The floating point information
4342 object was converted from a dict to a specialized structseq object.
4343
Georg Brandl3ee81df2008-05-17 18:14:43 +00004344- Patch #1816: Added sys.flags structseq. It exposes the status of
4345 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004346
Georg Brandl3ee81df2008-05-17 18:14:43 +00004347- Objects/structseq.c: Implemented new structseq representation. The
4348 patch makes structseqs (e.g. the return value of os.stat) more
4349 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004350
Georg Brandl3ee81df2008-05-17 18:14:43 +00004351- Patch #1700288: added a type attribute cache that caches method
4352 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004353
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004354- Bug #1776: __import__() no longer accepts filenames on any platform.
4355 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004356
Georg Brandlaed6c662008-01-07 17:25:53 +00004357- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4358
Georg Brandl3ee81df2008-05-17 18:14:43 +00004359- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4360 envvar and sys.dont_write_bytecode attribute. All these can be set
4361 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004362
Georg Brandl3ee81df2008-05-17 18:14:43 +00004363- Improve some exception messages when Windows fails to load an
4364 extension module. Now we get for example '%1 is not a valid Win32
4365 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004366
Georg Brandl3ee81df2008-05-17 18:14:43 +00004367- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00004368
Georg Brandl3ee81df2008-05-17 18:14:43 +00004369- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4370 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004371
Christian Heimes0a8143f2007-12-18 23:22:54 +00004372- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004373 and INF. float("nan"), float("inf") and float("-inf") now work on
4374 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004375
Georg Brandl3ee81df2008-05-17 18:14:43 +00004376- Compiler now generates simpler and faster code for dictionary
4377 literals. The oparg for BUILD_MAP now indicates an estimated
4378 dictionary size. There is a new opcode, STORE_MAP, for adding
4379 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004380
Georg Brandl3ee81df2008-05-17 18:14:43 +00004381- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004383- Issue #1620: New property decorator syntax was modifying the
4384 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004385
Georg Brandl3ee81df2008-05-17 18:14:43 +00004386- Issue #1538: Avoid copying string in split/rsplit if the split char
4387 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004388
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004389- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004390 SystemError.
4391
Nick Coghlanef01d822007-12-03 12:55:17 +00004392- PEP 366: Allow explicit relative imports when executing modules
4393 inside packages with the -m switch via a new module level
4394 __package__ attribute.
4395
Georg Brandl3ee81df2008-05-17 18:14:43 +00004396- Issue #1402: Fix a crash on exit, when another thread is still
4397 running, and if the deallocation of its frames somehow calls the
4398 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004399
Christian Heimes28104c52007-11-27 23:16:44 +00004400- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
4401
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00004402- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004403 attribute of an empty cell object.
4404
Georg Brandl3ee81df2008-05-17 18:14:43 +00004405- Issue #1460: The utf-7 incremental decoder did not accept truncated
4406 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004407
Georg Brandl3ee81df2008-05-17 18:14:43 +00004408- Patch #1739468: Directories and zipfiles containing a __main__.py
4409 file can now be directly executed by passing their name to the
4410 interpreter. The directory/zipfile is automatically inserted as the
4411 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004412
Georg Brandl3ee81df2008-05-17 18:14:43 +00004413- Issue #1265: Fix a problem with sys.settrace, if the tracing
4414 function uses a generator expression when at the same time the
4415 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004416
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004417- sets and frozensets now have an isdisjoint() method.
4418
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004419- optimize the performance of builtin.sum().
4420
Neal Norwitz44f326e2007-10-05 05:29:17 +00004421- Fix warnings found by the new version of the Coverity checker.
4422
Georg Brandl21e99f42010-03-07 15:23:59 +00004423- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004424 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4425 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004426
Georg Brandl3ee81df2008-05-17 18:14:43 +00004427- Issue #1686386: Tuple's tp_repr did not take into account the
4428 possibility of having a self-referential tuple, which is possible
4429 from C code. Nor did object's tp_str consider that a type's tp_str
4430 could do something that could lead to an inifinite recursion.
4431 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4432 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004433
Georg Brandl3ee81df2008-05-17 18:14:43 +00004434- Issue #1164: It was possible to trigger deadlock when using the
4435 'print' statement to write to a file since the GIL was not released
4436 as needed. Now PyObject_Print() does the right thing along with
4437 various tp_print implementations of the built-in types and those in
4438 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004439
Georg Brandl3ee81df2008-05-17 18:14:43 +00004440- Issue #1147: Exceptions were directly allowing string exceptions in
4441 their throw() method even though string exceptions no longer
4442 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004443
Georg Brandl3ee81df2008-05-17 18:14:43 +00004444- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00004447- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004448 PyObject_Call() never calling back out to Python code to trigger
4449 recursion depth updates/checks. Required the creation of a static
4450 RuntimeError instance in case normalizing an exception put the
4451 recursion check value past its limit. Fixes crashers
4452 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004468 __*__ attributes. (Some already existed, e.g., __doc__ and
4469 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004470
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004471- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00004478 "except E as target:". This is to provide forwards compatibility
4479 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004487 setting a plain string, ie don't expand to single letter identifiers.
4488
Raymond Hettinger13936692007-04-11 18:40:58 +00004489- Request #1191699: Slices can now be pickled.

4499
Guido van Rossum143b5642007-03-23 04:58:42 +00004500- Bug #1683368: The object.__init__() and object.__new__() methods are
4501 now stricter in rejecting excess arguments. The only time when
4502 either allows excess arguments is when it is not overridden and the
4503 other one is. For backwards compatibility, when both are
4504 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004505 warning later). Also, type.__init__() insists on the same signature
4506 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004507
Georg Brandl3ee81df2008-05-17 18:14:43 +00004508- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4509 object to complex using its __complex__() method before falling back
4510 to the __float__() method. Therefore, the functions in the cmath
4511 module now can operate on objects that define a __complex__()
4512 method.

4529
Georg Brandl7b9c5552007-03-12 14:30:05 +00004530- Bug #1678647: write a newline after printing an exception in any
4531 case, even when converting the value to a string failed.
4532
Georg Brandl871f1bc2007-03-12 13:17:36 +00004533- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004534 its argument, if it exists. If not, it will work like before. This
4535 allows customizing the output of dir() in the presence of a
4536 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004537
Collin Winter276887b2007-03-12 16:11:39 +00004538- Patch #922167: Python no longer segfaults when faced with infinitely
4539 self-recursive reload() calls (as reported by bug #742342).

4545 parthensized forms. This means complex(repr(x)) now works instead of
4546 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004547
Georg Brandlaa2321b2007-03-07 00:40:28 +00004548- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004549 makes the filenames the warning module prints much more sensible
4550 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004551

Georg Brandl0fca97a2007-03-05 22:28:08 +00004563- Patch #1674228: when assigning a slice (old-style), check for the
4564 sq_ass_slice instead of the sq_slice slot.
4565
Georg Brandl3ee81df2008-05-17 18:14:43 +00004566- When printing an unraisable error, don't print exceptions. before
4567 the name. This duplicates the behavior whening normally printing
4568 exceptions.

5191
Georg Brandl3ee81df2008-05-17 18:14:43 +00005192- unittest now verifies more of its assumptions. In particular,

5194 accepted in TestSuite.addTest(). This should cause no
5195 incompatibility since it never made sense with ordinary subclasses
5196 -- the failure just occurred later, with a more cumbersome
5197 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005478- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5479 with RFC 3207 and forgets any knowledge obtained from the server not
5480 obtained from the TLS negotiation itself. Patch contributed by Bill
5481 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005482
Georg Brandl3ee81df2008-05-17 18:14:43 +00005483- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005484 that the SMTP.starttls() caller no longer needs to call ehlo()
5485 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005486 does not claim to support starttls. Adds the
5487 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5568 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5569 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005586 time so that opening a database previously created with the DB_DUP
5587 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5588 opens. Specifically: dictionary assignment to a DB object will
5589 replace all values for a given key when the database allows
5590 duplicate values. DB users should use DB.put(k, v) when they want
5591 to store duplicates; not DB[k] = v.

5598 characters with ASCII value less than 32. Also, it correctly quotes
5599 dots only if they occur on a single line, as opposed to the previous
5600 behavior of quoting dots if they are the second character of any
5601 line.

5924-----
5925
Georg Brandl3ee81df2008-05-17 18:14:43 +00005926- Unified naming convention for free lists and their limits. All free
5927 lists in Object/ are named ``free_list``, the counter ``numfree``
5928 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5929 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005930
Georg Brandl3ee81df2008-05-17 18:14:43 +00005931- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5932 to ``PyTuple_SetItem``, it can be used to populate a brand new
5933 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005934
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005935- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005936
Georg Brandl3ee81df2008-05-17 18:14:43 +00005937- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5938 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5939 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005940
5941- Patch #1720595: add T_BOOL to the range of structmember types.
5942
5943- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5944 ``PyFloat_GetInfo()`` to the float API.
5945
Georg Brandl3ee81df2008-05-17 18:14:43 +00005946- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5947 of w# format code incorrectly truncated the length to an int, even
5948 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5949 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005950
Georg Brandl3ee81df2008-05-17 18:14:43 +00005951- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5952 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005953
Georg Brandl3ee81df2008-05-17 18:14:43 +00005954- PEP 3123: Provide forward compatibility with Python 3.0, while
5955 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5956 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005957
Georg Brandl3ee81df2008-05-17 18:14:43 +00005958- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5959 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005960
5961- Patch #1733960: Allow T_LONGLONG to accept ints.
5962
5963- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5964
Christian Heimes000a0742008-01-03 22:16:32 +00005965- Added a new API function ``PyImport_ImportModuleNoBlock``.
5966
Georg Brandl6caad7d2008-01-26 14:19:22 +00005967- Bug #1637022: Prefix AST symbols with _Py_.
5968
5969- Fix some leftovers from the conversion from int to Py_ssize_t
5970 (relevant to strings and sequences of more than 2**31 items).
5971
5972- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5973 outside of pystate.c and should not be necessary.
5974
Georg Brandl3ee81df2008-05-17 18:14:43 +00005975- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5976 absolute imports. In earlier versions they might have used relative
5977 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005978
Georg Brandl3ee81df2008-05-17 18:14:43 +00005979- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5980 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005981
Georg Brandl3ee81df2008-05-17 18:14:43 +00005982- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5983 macro so it can be used as an expression.

5988
Georg Brandl3ee81df2008-05-17 18:14:43 +00005989- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5990 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5991 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5992 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005993
Georg Brandl3ee81df2008-05-17 18:14:43 +00005994- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5995 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006007- Removed the macfs module. It had been deprecated since Python 2.5.
6008 This lead to the deprecation of macostools.touched() as it relied
6009 solely on macfs and was a no-op under OS X.
