33 exception of canonical and is_canonical) now accept instances of int
34 and long wherever a Decimal instance is accepted, and implicitly
35 convert that argument to Decimal. Previously only some arguments

77 and read operations on write-only file objects. On Windows, the system C
78 library would return a bogus result; on Solaris, it was possible to crash
79 the interpreter. Patch by Stefan Krah.

109 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +0000110 strings corresponding to subnormal values, (3) a memory leak for
111 some values large enough to cause overflow, and (4) a number of
112 flaws that could lead to incorrectly rounded results.
Mark Dickinson8efef5c2010-01-12 22:23:56 +0000113
Brett Cannon3ffa43d2010-01-14 20:00:28 +0000114- Issue #7319, #7770: Silence DeprecationWarning by default when -3 is not

131 in XML processing instructions and comments. These raw characters are
132 allowed by the XML specification, and are necessary when outputting e.g.
133 PHP code in a processing instruction. Patch by Neil Muller.

149 file position when calling `truncate()`. It would previously change the
150 file position to the given argument, which goes against the tradition of
151 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

156 :class:`zipfile.ZipExtFile` class used to represent files stored inside
157 an archive. The new implementation is significantly faster and can
158 be wrapped in a :class:`io.BufferedReader` object for more speedups.
159 It also solves an issue where interleaved calls to `read()` and

170 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
171 encoded string for them. This ensure that the upload and register commands
172 send the right values to PyPI without any error.
173
R. David Murrayed44dfa2010-01-16 05:15:17 +0000174- Issue #1670765: Prevent email.generator.Generator from re-wrapping

Benjamin Petersonecdae192010-01-04 00:43:01 +0000252- The __complex__ method is now looked up on the class of instances to make it
253 consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000255- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
256 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
257
Mark Dickinson1b34d252010-01-01 17:27:30 +0000258- Issue #5080: A number of functions and methods previously produced a
259 DeprecationWarning when passed a float argument where an integer was
260 expected. These functions and methods now raise TypeError instead.
261 The majority of the effects of this change are in the extension
262 modules, but some core functions and methods are affected: notably
263 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
264 methods.
265
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000266- Issue #7604: Deleting an unset slotted attribute did not raise an

274
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000275- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
276 used to drop the time part of the result.
277
Mark Dickinson46572832009-12-27 14:55:57 +0000278- Issue #1811: improve accuracy and cross-platform consistency for
279 true division of integers: the result of a/b is now correctly
280 rounded for ints a and b (at least on IEEE 754 platforms), and in
281 particular does not depend on the internal representation of a long.
282
Ezio Melottif84caf42009-12-24 22:25:17 +0000283- Issue #6108: unicode(exception) and str(exception) should return the same

285
Ronald Oussoren92919a62009-12-24 13:30:58 +0000286- Issue #6834: replace the implementation for the 'python' and 'pythonw'

Eric Smithc4ab8332009-11-29 17:40:57 +0000431- Issue #3382: 'F' formatting for float and complex now convert the
432 result to upper case. This only affects 'inf' and 'nan', since 'f'
433 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000434

447 on MacOSX 10.6.
448
Mark Dickinsonb678de82009-11-19 18:41:49 +0000449- Issue #7117: repr(x) for a float x returns a result based on the
450 shortest decimal string that's guaranteed to round back to x under
451 correct rounding (with round-half-to-even rounding mode).
452 Previously it gave a string based on rounding x to 17 decimal digits.
453 repr(x) for a complex number behaves similarly. On platforms where
454 the correctly-rounded strtod and dtoa code is not supported (see below),
455 repr is unchanged.
456
457- Issue #7117: On almost all platforms: float-to-string and
458 string-to-float conversions within Python are now correctly rounded.
459 Places these conversions occur include: str for floats and complex
460 numbers; the float and complex constructors; old-style and new-style
461 numeric formatting; serialization and deserialization of floats and
462 complex numbers using marshal, pickle and json; parsing of float and
463 imaginary literals in Python code; Decimal-to-float conversion.
464
465 The conversions use a Python-adapted version of David Gay's
466 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
467 functions. This code is supported on Windows, and on Unix-like
468 platforms using gcc, icc or suncc as the C compiler. There may be a
469 small number of platforms on which correct operation of this code
470 cannot be guaranteed, so the code is not used: notably, this applies
471 to platforms where the C double format is not IEEE 754 binary64, and
472 to platforms on x86 hardware where the x87 FPU is set to 64-bit
473 precision and Python's configure script is unable to determine how
474 to change the FPU precision. On these platforms conversions use the
475 platform strtod and dtoa, as before.
476
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000477- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000478 now uses the correctly-rounded string <-> float conversions
479 described above (when available), and so produces correctly rounded
480 results that will display nicely under the float repr. There are
481 two related small changes: (1) round now accepts any class with an
482 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000483 floats for the second argument), and (2) an excessively large second
484 integer argument (e.g., round(1.234, 10**100)) no longer raises an
485 exception.

626
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000627- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
628 (1) inf and nan strings with trailing whitespace were incorrectly
629 rejected; (2) parsing of strings representing infinities and nans
630 was locale aware; and (3) the interpretation of fromhex('-nan')
631 didn't match that of float('-nan').
632
Eric Smitha985a3a2009-05-05 18:26:08 +0000633- Issue #5920: For float.__format__, change the behavior with the
634 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
635 to be like 'g' but with at least one decimal point and with a
636 default precision of 12. Previously, the behavior the same but with
637 a default precision of 6. This more closely matches str(), and
638 reduces surprises when adding alignment flags to the empty
639 presentation type. This also affects the new complex.__format__ in
640 the same way.
641
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000642- Issue #5890: in subclasses of 'property' the __doc__ attribute was
643 shadowed by classtype's, even if it was None. property now
644 inserts the __doc__ into the subclass instance __dict__.
645
Antoine Pitrou653dece2009-05-04 18:32:32 +0000646- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Mark Dickinson95bc9802009-04-24 12:46:53 +0000666- Issue #5816: complex(repr(z)) now recovers z exactly, even when
667 z involves nans, infs or negative zeros.
668
Eric Smithaca19e62009-04-22 13:29:05 +0000669- Implement PEP 378, Format Specifier for Thousands Separator, for

683
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000684- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000685 was giving 5e15+2; round(-0.0) was losing the sign of the zero.

Ronald Oussorene0154ed2009-03-30 23:10:35 +0000701- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
702 the end sys.path, for compatibility with the system install of Python.
703
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000704- Issue #4688: Add a heuristic so that tuples and dicts containing only
705 untrackable objects are not tracked by the garbage collector. This can
706 reduce the size of collections and therefore the garbage collection overhead
707 on long-running programs, depending on their particular use of datatypes.
708
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000709- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
710 improve its performance. Long divisions and remainder operations
711 are now between 50% and 150% faster.
712
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000713- Issue #4258: Make it possible to use base 2**30 instead of base
714 2**15 for the internal representation of integers, for performance
715 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
716 --enable-big-digits option to configure, which overrides the
717 default. Add sys.long_info structseq to provide information about
718 the internal format.
719
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000720- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
721 result traceback.__members__ no longer exists.)
722
Mark Dickinson6b265f12009-03-18 16:07:26 +0000723- Issue #4474: PyUnicode_FromWideChar now converts characters outside
724 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
725 and sizeof(Py_UNICODE) == 2.
726
Eric Smith6f42edb2009-03-14 11:57:26 +0000727- Issue #5237: Allow auto-numbered fields in str.format(). For
728 example: '{} {}'.format(1, 2) == '1 2'.
729
Brett Cannon6c4cff02009-03-11 04:51:06 +0000730- Issue #3652: Make the 'line' argument for warnings.showwarning() a
731 requirement. Means the DeprecationWarning from Python 2.6 can go away.
732
Eric Smithe9fb6862009-02-20 14:02:36 +0000733- Issue #5247: Improve error message when unknown format codes are
734 used when using str.format() with str, unicode, long, int, and
735 float arguments.
736
Raymond Hettinger08259e82009-02-18 23:10:19 +0000737- Running Python with the -3 option now also warns about classic division
738 for ints and longs.
739
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000740- Issue #5260: Long integers now consume less memory: average
741 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
742 on a 64-bit system.
743
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000744- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
745 rotating the object pointer by 4 bits to the right.
746
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000747- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
748 it now forces its argument to double before testing for infinity.
749
Benjamin Petersone18ef192009-01-20 14:21:16 +0000750- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
751
Georg Brandl29c6a282009-04-05 20:23:13 +0000752- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000753 were suppressing all exceptions. These include list(), filter(), map(),
754 zip(), and bytearray().
755
Benjamin Peterson596d3062009-01-19 15:42:23 +0000756- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
757 functions.
758
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000759- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

763
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000764- Issue #4935: The overflow checking code in the expandtabs() method common
765 to str, bytes and bytearray could be optimized away by the compiler, letting
766 the interpreter segfault instead of raising an error.
767
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000768- Issue #3720: Fix a crash when an iterator modifies its class and removes its

774
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000775- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
776 collecting the oldest generation) so that allocating lots of objects without
777 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000778 Martin von Löwis at

782
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000783- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
784 an existing .py counterpart, override the co_filename attributes of all
785 code objects if the original filename is obsolete (which can happen if the
786 file has been renamed, moved, or if it is accessed through different paths).
787 Patch by Ziga Seilnacht and Jean-Paul Calderone.
788
Martin v. Löwis5344c992009-01-02 20:32:55 +0000789- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000791- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
792 file with `str' filename on Windows.
793
Antoine Pitrouaa687902009-01-01 14:11:22 +0000794- Issue #3680: Reference cycles created through a dict, set or deque iterator
795 did not get collected.
796
Nick Coghlan180e4002008-12-30 01:18:48 +0000797- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
798 where the tp_hash and tp_dict slots are both NULL.
799
Benjamin Peterson7af65562008-12-29 17:56:58 +0000800- Issue #4764: With io.open, IOError.filename is set when trying to open a
801 directory on POSIX systems.
802
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000803- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

807 bytearray.translate(). It was always allowed for bytes.translate().
808
Skip Montanarof205c132008-12-23 03:30:15 +0000809- Added test case to ensure attempts to read from a file opened for writing
810 fail.
811
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000812- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

823
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000824- Issue #4597: Fixed several opcodes that weren't always propagating
825 exceptions.
826
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000827- Issue #4445: Replace "sizeof(PyStringObject)" with
828 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
829 str instances. On a typical machine this saves 3 bytes of memory
830 (on average) per string allocation.
831
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000832- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
833 interpreter to abort ("Fatal Python error: Could not reset the stack!")
834 instead of throwing a MemoryError.
835
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000836- Issue #3689: The list reversed iterator now supports __length_hint__

838
Benjamin Petersonc078f922008-11-21 22:27:24 +0000839- Issue #4367: Python would segfault during compiling when the unicodedata

841
Vinay Sajip213faca2008-12-03 23:22:58 +0000842- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000843 method on file objects with closefd=False. The file descriptor is still
844 kept open but the file object behaves like a closed file. The ``FileIO``
845 object also got a new readonly attribute ``closefd``.
846
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000847- Issue #4348: Some bytearray methods returned that didn't cause any change to
848 the bytearray, returned the same bytearray instead of a copy.
849
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000850- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +0000862- Issue #4209: Enabling unicode_literals and the print_function in the same
863 __future__ import didn't work.
864
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000865- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000866 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000868- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
869 returned a path longer than MAX_PATH. (But It's doubtful this code path is
870 really executed because I cannot move to such directory on win2k)
871
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000872- Issue #4069: When set.remove(element) is used with a set element, the element
873 is temporarily replaced with an equivalent frozenset. But the eventual
874 KeyError would always report the empty frozenset([]) as the missing key. Now
875 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000895- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
896 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
897 step. This avoids problems with counting UTF-8 bytes that ignores the effect
898 of using the replace error handler in PyUnicode_DecodeUTF8().
899
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000900- Issue #3739: The unicode-internal encoder now reports the number of characters

902
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000903- Issue #2422: When compiled with the ``--with-valgrind`` option, the

905 Valgrind. This gives improved memory leak detection when running
906 under Valgrind, while taking advantage of pymalloc at other times.

R. David Murray820b0ea2009-12-03 23:57:59 +00002128 file in the Lib/test directory, which might be read-only for the

R. David Murrayda826892009-11-15 00:04:32 +00002131- Issue #7324: add a sanity check to regrtest argument parsing to

2141
Antoine Pitrou59c44f32009-10-30 17:07:08 +00002142- Issue #7222: Make thread "reaping" more reliable so that reference
2143 leak-chasing test runs give sensible results. The previous method of
2144 reaping threads could return successfully while some Thread objects were
2145 still referenced. This also introduces a new private function:
2146 :func:`thread._count()`.
2147
R. David Murray282396f2009-10-18 21:12:37 +00002148- Issue #7151: fixed regrtest -j so that output to stderr from a test no

2150
Antoine Pitrou58d2f262009-10-10 20:52:11 +00002151- Issue #7055: test___all__ now greedily detects all modules which have an

2153
R. David Murray14dcd432009-10-14 13:58:07 +00002154- Issue #7058: Added save/restore for things like sys.argv and cwd to

2164 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

2166 skip the tests if DISPLAY is defined but can't be used.
2167
Antoine Pitrou4698d992009-05-31 14:20:14 +00002168- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running

2170
Nick Coghlan5533ff62009-04-22 15:26:04 +00002171- Issue #5354: New test support function import_fresh_module() makes
2172 it easy to import both normal and optimised versions of modules.
2173 test_heapq and test_warnings have been adjusted to use it, tests for
2174 other modules with both C and Python implementations in the stdlib
2175 can be adjusted to use it over time.

2182
R. David Murray41448c52009-03-31 19:57:24 +00002183- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00002184 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00002185 from test support, which does the conversion.

2283Core and Builtins
2284-----------------
2285
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002286- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2287
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002288- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2289 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2290 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2291 ``printf`` function, whereas PyString_FromFormat has an independent
2292 implementation and uses "%zd" on all platforms for size_t values.
2293 This makes a difference on win64, where ``printf`` needs "%Id" to display
2294 64bit values.
2295
Benjamin Peterson97179b02008-09-09 20:55:01 +00002296- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2297 error.
2298
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002299- Issue #3777: long() applied to a float object now always return a long
2300 object; previously an int would be returned for small values. the __long__
2301 method is allowed to return either an int or a long, but the behaviour of
2302 float objects should not change to respect backward compatibility.
2303
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002304- Issue #3751: str.rpartition would perform a left-partition when called with
2305 a unicode argument.
2306
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002307- Issue #3683: Fix compilation when --without-threads is given.
2308
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002309- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002310 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002311 was correctly parsed but parsing of subsequent arguments failed.
2312
Vinay Sajip35e3b032008-09-01 14:33:59 +00002313- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002314 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2315 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2316 when given a tuple of classes as second argument, were looking up
2317 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2318 type object.
2319
Neal Norwitz18aa3882008-08-24 05:04:52 +00002320- Fix crashes on memory allocation failure found with failmalloc.
2321
2322- Fix memory leaks found with valgrind and update suppressions file.
2323
2324- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2325
2326- Fix problem using wrong name in decimal module reported by pychecker.
2327
Christian Heimes7d4c3172008-08-22 19:47:25 +00002328- Silenced another compiler warning about a used but not defined
2329 function 'stringlib_contains_obj'.
2330
Benjamin Peterson712ee922008-08-24 18:10:20 +00002331- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2332 ``__delslice__``.
2333
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002334- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2335 library targets in the Makefile.
2336
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002337- Issue #1204: The configure script now tests for additional libraries
2338 that may be required when linking against readline. This fixes issues
2339 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
2340

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00002349- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
2350 stack usage in the case of deeply nested objects.
2351

2361
Nick Coghland2e09382008-09-11 12:11:06 +00002362- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002363 return a list or None rather than a custom object.
2364
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002365- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2389 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2390 for catch_warnings() also led to an improvement in the raising of a
2391 DeprecationWarning related to warnings.warn_explicit().
2392
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002393- The deprecation warnings for the old camelCase threading API were removed.

2421 exploitation of poor argument checking.
2422
Gerhard Häringef2276b2008-09-12 13:54:06 +00002423- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002457What's New in Python 2.6 beta 3?
2458================================
2459
Barry Warsaw07a4a382008-08-21 01:15:08 +00002460*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002461
2462Core and Builtins
2463-----------------
2464
Guido van Rossumf8402962008-08-20 15:01:50 +00002465- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2466 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2467 extensions do not automatically benefit from the class attribute
2468 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2469 to their tp_flags field if they care. This is a backwards
2470 compatibility feature; in 3.0, all types will use the cache by
2471 default.
2472
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002473- Keyword arguments can now follow starred arguments. (``f(a, *args,
2474 keyword=23)`` is now valid syntax.)
2475
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002476- ctypes function pointers that are COM methods have a boolean True
2477 value again.
2478
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002479- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2480 by denying s# to parse objects that have a releasebuffer procedure,
2481 and introducing s*.
2482
Georg Brandl1e13ea92008-08-11 09:07:59 +00002483- Issue #3537: Fix an assertion failure when an empty but presized dict
2484 object was stored in the freelist.
2485
Mark Dickinsonb6467572008-08-04 21:30:09 +00002486- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2487 ValueError consistently across platforms.
2488
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002489- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2490 (64bit Unix, for example), unichr() would truncate its argument and return
2491 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2492
Neal Norwitze7d8be82008-07-31 17:17:14 +00002493- Apply security patches from Apple.
2494
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002495- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2496 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2497
Antoine Pitrou92f82162008-07-25 22:22:08 +00002498- Issue #1819: function calls with several named parameters are now on
2499 average 35% faster (as measured by pybench).
2500
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002501- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2502 the python debugger steps into a class statement: the free variables (local
2503 variables defined in an outer scope) would be deleted from the outer scope.
2504
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002505- Issue #2620: Overflow checking when allocating or reallocating memory
2506 was not always being done properly in some python types and extension
2507 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2508 all been updated to perform better checks and places in the code that
2509 would previously leak memory on the error path when such an allocation
2510 failed have been fixed.
2511

2513-------
2514
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002515- Issue #3612: Added some missing basic types in ctypes.wintypes.
2516
Benjamin Petersone977ad42008-08-20 01:42:01 +00002517- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2518 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2519
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002520- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2521 version reported by these tools does not necessarily follow the python
2522 version numbering scheme, so the module is less strict when parsing it.
2523
Nick Coghlanf70385a2008-08-18 12:42:46 +00002524- Issue #2235: Added Py3k warnings for types which will become unhashable
2525 under the stricter __hash__ inheritance rules in 3.0. Several types
2526 which did not meet the rules for hash invariants and were already
2527 unhashable in 3.0 have now been explicitly flagged as unhashable in
2528 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2529 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2530
Brett Cannon88f801d2008-08-18 00:46:22 +00002531- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2532 imported into the module but exposed as part of the module's API.
2533
Brett Cannon7b96f072008-08-18 00:41:11 +00002534- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2535
Brett Cannon46225e72008-08-18 00:36:52 +00002536- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002538- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2539
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002540- Issue #3575: Incremental decoder's decode function now takes bytearray
2541 by using 's*' instead of 't#'.
2542
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002543- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002544 fails unicode conversion on 2nd parameter. (windows only)
2545
Facundo Batista94f243a2008-08-17 03:38:39 +00002546- Issue 2464. urllib2 now supports a malformation in the URL received
2547 in a redirect.
2548
Brett Cannonabe423e2008-08-16 21:47:07 +00002549- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002550 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002551
Facundo Batistaeb90b782008-08-16 14:44:07 +00002552- Issue #2776: fixed small issue when handling an URL with double slash
2553 after a 302 response in the case of not going through a proxy.
2554
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002555- Issue #2676: in the email package, content-type parsing was hanging on
2556 pathological input because of quadratic or exponential behaviour of a
2557 regular expression.
2558
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002559- Issue #3476: binary buffered reading through the new "io" library is now
2560 thread-safe.
2561
Brett Cannonbf3157b2008-08-14 05:00:03 +00002562- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2563 since mimetools itself is deprecated. Because modules are cached, all
2564 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2565
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002566- Issue #3134: shutil referenced undefined WindowsError symbol.
2567
Robert Schuppenies14646332008-08-10 11:01:53 +00002568- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2569 menu entries were not deleted.

2597 raised an AttributeError.
2598
Benjamin Peterson01a24322008-07-28 23:35:27 +00002599- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002600 asking for a specific length. This problem only affected files opened

2643 interaction with the tp_hash slot (added in 2.6b2) are now documented
2644
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002645- Issue #643841: The language reference now provides more detailed

2652================================
2653
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002654*Release date: 17-Jul-2008*

2657-----------------
2658
Georg Brandl3e483f62008-07-16 22:57:41 +00002659- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2660 its methods now allow for items objects that can be converted to
2661 an integer using operator.index().
2662
Mark Dickinson64b7e502008-07-16 09:40:03 +00002663- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2664 produced a ValueError instead of giving the correct float.
2665
Eric Smitha5fa5a22008-07-16 00:11:49 +00002666- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2667 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2668
Mark Dickinson7103aa42008-07-15 19:08:33 +00002669- Issue #3008: the float type has a new instance method 'float.hex'
2670 and a new class method 'float.fromhex' to convert floating-point
2671 numbers to and from hexadecimal strings, respectively.
2672
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002673- Issue #2235: __hash__ is once again inherited by default. To allow
2674 collections.Hashable to remain meaningful in the presence of the
2675 default hash implementation (object.__hash__), it is now possible
2676 to explicit block inheritance of hash by setting __hash__=None at
2677 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2678 level.
2679
Nick Coghlanb028f502008-07-13 14:52:36 +00002680- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2681 the parent module cannot be found while performing an absolute import.
2682 This means that an incorrectly defined __package__ attribute will
2683 now only prevent relative imports in that module rather than causing
2684 all imports from that module to fail.
2685
Nick Coghlan14ff9942008-07-08 14:21:42 +00002686- Issue #2517: Allow unicode messages in Exceptions again by correctly

2695 threading.local: the first member set by a thread could be saved in
2696 another thread's dictionary.
2697
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002698- Issue #3004: Minor change to slice.indices(): the start and stop
2699 arguments are now treated identically, making the behaviour easier
2700 to describe and understand. For example, slice(None, -10,
2701 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2702 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2703 10, -1).
2704
Georg Brandl278fc502008-07-19 12:46:12 +00002705- Issue #3219: Calling a function with repeated keyword arguments,
2706 f(a=2, a=23), would not cause a syntax error. This was a regression
2707 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002708
Georg Brandl278fc502008-07-19 12:46:12 +00002709- Issue #2862: Make int and float freelist management consistent with
2710 other freelists. Changes their CompactFreeList apis into
2711 ClearFreeList apis and calls them via gc.collect().

2717 api functions without holding the GIL, which could lead to a fatal
2718 error when they failed.
2719
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002720- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002745- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2746 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002747 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002748 content-length. The problem had been corrected in the 2.4 branch, but never
2749 merged into trunk.
2750

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002764- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2766
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002767- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

3152
Brett Cannonb61d8012008-05-11 23:39:04 +00003153- ``Lib/lib-old`` is now added to sys.path.
3154
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003155- On MacOS X it is now possible to install the framework in 64-bit
3156 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003157 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003158
3159 This is controlled by the configure argument ``--with-universal-archs``:
3160
3161 - ``--with-universal-archs=all``: install 4-way universal
3162
3163 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3164
3165 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3166
3167 This option should be used in combination with ``--enable-universalsdk=``.
3168
3169 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00003178
3179- The PyString functions have been renamed to PyBytes. A batch of
3180 defines were added so that the linker still sees the original
3181 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003219- Issue #1631171: Re-implement the 'warnings' module in C (the
3220 original Python code has been kept as backup). This will allow for
3221 using the 'warning's machinery in such places as the parser where
3222 use of pure Python code is not possible. Both the ``showarning()``
3223 and ``formatwarning()`` gain an optional 'line' argument which is
3224 not called by default for backwards-compatibility reasons. Setting
3225 ``warnings.showwarning()`` to an implementation that lacks support
3226 for the ``line`` argument will raise a DeprecationWarning.

3250
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003251- The getpass module has been improved on Unix. It now uses /dev/tty
3252 by default and uses stderr instead of stdout. A GetPassWarning is
3253 issued when input echo cannot be controlled.

3265 implementation detail of the public ``types`` module, has been
3266 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00003267
Georg Brandl3ee81df2008-05-17 18:14:43 +00003268- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003269 extension modules between 32 and 64 bit platforms. See the distutls
3270 build documentation for more information.

3273 threads at once without fear of crashing the Python interpreter. If
3274 file.close() is called while an object is in use by another thread
3275 an IOError exception will be raised and the file will not be closed.
3276
Thomas Hellerf7906482008-04-04 19:43:25 +00003277- The bundled libffi copy is now in sync with the recently released

3282 so the controlled environment will more closely mirror the typical
3283 script environment. This supports setup.py scripts that refer to
3284 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003289- Issue #2550: The approach used by client/server code for obtaining
3290 ports to listen on in network-oriented tests has been refined in an
3291 effort to facilitate running multiple instances of the entire
3292 regression test suite in parallel without issue.
3293 test_support.bind_port() has been fixed such that it will always
3294 return a unique port -- which wasn't always the case with the
3295 previous implementation, especially if socket options had been set
3296 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3297 new implementation of bind_port() will actually raise an exception
3298 if it is passed an AF_INET/SOCK_STREAM socket with either the
3299 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3300 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3301 the socket it's been passed. This currently only applies to
3302 Windows. This option prevents any other sockets from binding to the
3303 host/port we've bound to, thus removing the possibility of the
3304 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3305 when a second SOCK_STREAM socket binds and accepts to a host/port
3306 that's already been bound by another socket. The optional preferred
3307 port parameter to bind_port() has been removed. Under no
3308 circumstances should tests be hard coding ports!
3309
3310 test_support.find_unused_port() has also been introduced, which will
3311 pass a temporary socket object to bind_port() in order to obtain an
3312 unused port. The temporary socket object is then closed and
3313 deleted, and the port is returned. This method should only be used
3314 for obtaining an unused port in order to pass to an external program
3315 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3316 a parameter to a server-oriented class that doesn't give you direct
3317 access to the underlying socket used.
3318
3319 Finally, test_support.HOST has been introduced, which should be used
3320 for the host argument of any relevant socket calls (i.e. bind and
3321 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003322
3323 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003324 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003325 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3326 test_asynchat and test_socket_ssl.
3327
Georg Brandl3ee81df2008-05-17 18:14:43 +00003328 It is now possible for multiple instances of the regression test
3329 suite to run in parallel without issue.

3596-----------------
3597
Fred Drakea8ee94b2008-03-01 02:45:07 +00003598- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003599 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003604
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003605- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003606 issue 215555 for a discussion.
3607
Eric Smitha73fbe72008-02-23 03:09:44 +00003608- Added the future_builtins module, which contains hex() and oct().
3609 These are the PEP 3127 version of these functions, designed to be
3610 compatible with the hex() and oct() builtins from Python 3.0. They
3611 differ slightly in their output formats from the existing, unchanged
3612 Python 2.6 builtins. The expected usage of the future_builtins
3613 module is:
3614 from future_builtins import hex, oct
3615
Eric Smith7ef40bf2008-02-20 23:34:22 +00003616- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3617 exponents for exponents with absolute value < 100. Follows C99
3618 standard. This is a change on Windows, which would use 3 digits.
3619 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3620 so that any alterations it does to the resulting string will be
3621 available in stringlib/formatter.h (for float.__format__).
3622
Eric Smith5a3c1352008-02-19 13:21:56 +00003623- Implemented PEP 3101, Advanced String Formatting. This adds a new
3624 builtin format(); a format() method for str and unicode; a
3625 __format__() method to object, str, unicode, int, long, float, and
3626 datetime; the class string.Formatter; and the C API
3627 PyObject_Format().
3628
Georg Brandl3ee81df2008-05-17 18:14:43 +00003629- Fixed several potential crashes, all caused by specially crafted
3630 __del__ methods exploiting objects in temporarily inconsistent
3631 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003632
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003633- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003634 prevent a possible crash: an Abstract Base Class would try to access
3635 a slot on a registered virtual subclass.

3641 in order to allow pymalloc to free more arenas. Python may give back
3642 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003643
Georg Brandl3ee81df2008-05-17 18:14:43 +00003644- Issue #2045: Fix an infinite recursion triggered when printing a
3645 subclass of collections.defaultdict, if its default_factory is set
3646 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003647
Christian Heimesf75dbef2008-02-08 00:11:31 +00003648- Fixed a minor memory leak in dictobject.c. The content of the free
3649 list was not freed on interpreter shutdown.
3650
Georg Brandl3ee81df2008-05-17 18:14:43 +00003651- Limit free list of method and builtin function objects to 256
3652 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003653
Georg Brandl3ee81df2008-05-17 18:14:43 +00003654- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3655 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003656 to compact the internal free lists of pre-allocted ints and floats.
3657
Georg Brandl3ee81df2008-05-17 18:14:43 +00003658- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3659 calls. Python expected the return type int but the fork familie
3660 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003661
Georg Brandl3ee81df2008-05-17 18:14:43 +00003662- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3663 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003664
Georg Brandl3ee81df2008-05-17 18:14:43 +00003665- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3666 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003667
Georg Brandl3ee81df2008-05-17 18:14:43 +00003668- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3669 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003670
Georg Brandl3ee81df2008-05-17 18:14:43 +00003671- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3672 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003673
Georg Brandl3ee81df2008-05-17 18:14:43 +00003674- Patch #1473257: generator objects gain a gi_code attribute. This is
3675 the same object as the func_code attribute of the function that
3676 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003677
Georg Brandl3ee81df2008-05-17 18:14:43 +00003678- Issue #1920: "while 0" statements were completely removed by the
3679 compiler, even in the presence of an "else" clause, which is
3680 supposed to be run when the condition is false. Now the compiler
3681 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003682
Guido van Rossumeead05f2008-01-24 18:21:02 +00003683- A few crashers fixed: weakref_in_del.py (issue #1377858);
3684 loosing_dict_ref.py (issue #1303614, test67.py);
3685 borrowed_ref_[34].py (not in tracker).
3686
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003687- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003688 suppressed while an extension is loaded by calling SetErrorMode in
3689 dynload_win.c. The error is still reported properly.
3690
Georg Brandl3ee81df2008-05-17 18:14:43 +00003691- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003692 several extension methods and modules do not work without unicode
3693 support.
3694
Georg Brandl26543b12008-01-21 18:36:51 +00003695- Issue #1882: when compiling code from a string, encoding cookies in the
3696 second line of code were not always recognized correctly.
3697
Georg Brandl14404b62008-01-19 19:27:05 +00003698- Issue #1679: "0x" was taken as a valid integer literal.
3699
Georg Brandl6caad7d2008-01-26 14:19:22 +00003700- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003701 added.
3702
Christian Heimesc94e2b52008-01-14 04:13:37 +00003703- sys.float_info / PyFloat_GetInfo: The floating point information
3704 object was converted from a dict to a specialized structseq object.
3705
Georg Brandl3ee81df2008-05-17 18:14:43 +00003706- Patch #1816: Added sys.flags structseq. It exposes the status of
3707 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003708
Georg Brandl3ee81df2008-05-17 18:14:43 +00003709- Objects/structseq.c: Implemented new structseq representation. The
3710 patch makes structseqs (e.g. the return value of os.stat) more
3711 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003712
Georg Brandl3ee81df2008-05-17 18:14:43 +00003713- Patch #1700288: added a type attribute cache that caches method
3714 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003715
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003716- Bug #1776: __import__() no longer accepts filenames on any platform.
3717 The first parameter to __import__() must be a valid module name.

3720
Georg Brandl3ee81df2008-05-17 18:14:43 +00003721- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3722 envvar and sys.dont_write_bytecode attribute. All these can be set
3723 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003724
Georg Brandl3ee81df2008-05-17 18:14:43 +00003725- Improve some exception messages when Windows fails to load an
3726 extension module. Now we get for example '%1 is not a valid Win32
3727 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003728

Christian Heimes0a8143f2007-12-18 23:22:54 +00003734- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003735 and INF. float("nan"), float("inf") and float("-inf") now work on
3736 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003737
Georg Brandl3ee81df2008-05-17 18:14:43 +00003738- Compiler now generates simpler and faster code for dictionary
3739 literals. The oparg for BUILD_MAP now indicates an estimated
3740 dictionary size. There is a new opcode, STORE_MAP, for adding
3741 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003770- Patch #1739468: Directories and zipfiles containing a __main__.py
3771 file can now be directly executed by passing their name to the
3772 interpreter. The directory/zipfile is automatically inserted as the
3773 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003774
Georg Brandl3ee81df2008-05-17 18:14:43 +00003775- Issue #1265: Fix a problem with sys.settrace, if the tracing
3776 function uses a generator expression when at the same time the
3777 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003778
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003779- sets and frozensets now have an isdisjoint() method.
3780

3782
Neal Norwitz44f326e2007-10-05 05:29:17 +00003783- Fix warnings found by the new version of the Coverity checker.
3784
Georg Brandl3ee81df2008-05-17 18:14:43 +00003785- The enumerate() builtin function is no longer bounded to sequences
3786 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3787 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003788
Georg Brandl3ee81df2008-05-17 18:14:43 +00003789- Issue #1686386: Tuple's tp_repr did not take into account the
3790 possibility of having a self-referential tuple, which is possible
3791 from C code. Nor did object's tp_str consider that a type's tp_str
3792 could do something that could lead to an inifinite recursion.
3793 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3794 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003795
Georg Brandl3ee81df2008-05-17 18:14:43 +00003796- Issue #1164: It was possible to trigger deadlock when using the
3797 'print' statement to write to a file since the GIL was not released
3798 as needed. Now PyObject_Print() does the right thing along with
3799 various tp_print implementations of the built-in types and those in
3800 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003801
Georg Brandl3ee81df2008-05-17 18:14:43 +00003802- Issue #1147: Exceptions were directly allowing string exceptions in
3803 their throw() method even though string exceptions no longer
3804 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003805
Georg Brandl3ee81df2008-05-17 18:14:43 +00003806- Issue #1096: Prevent a segfault from getting the repr of a very
3807 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003808
Brett Cannon1e534b52007-09-07 04:18:30 +00003809- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003810 PyObject_Call() never calling back out to Python code to trigger
3811 recursion depth updates/checks. Required the creation of a static
3812 RuntimeError instance in case normalizing an exception put the
3813 recursion check value past its limit. Fixes crashers
3814 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003815
Georg Brandl3ee81df2008-05-17 18:14:43 +00003816- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003829- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003830 __*__ attributes. (Some already existed, e.g., __doc__ and
3831 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003832
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003833- Add -3 option to the interpreter to warn about features that are
3834 deprecated and will be changed/removed in Python 3.0.
3835
Georg Brandl2134e752007-05-21 20:34:16 +00003836- Patch #1686487: you can now pass any mapping after '**' in function
3837 calls.
3838
Collin Winter62903052007-05-18 23:11:24 +00003839- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003840 "except E as target:". This is to provide forwards compatibility
3841 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003842
Brett Cannon229cee22007-05-05 01:34:02 +00003843- Deprecate BaseException.message as per PEP 352.
3844
Georg Brandl3ee81df2008-05-17 18:14:43 +00003845- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003846 inherited from a builtin base.
3847
Vinay Sajip8549ce32007-05-06 17:53:37 +00003848- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003849 setting a plain string, ie don't expand to single letter identifiers.
3850
Raymond Hettinger13936692007-04-11 18:40:58 +00003851- Request #1191699: Slices can now be pickled.
3852
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003853- Request #1193128: str.translate() now allows a None argument for
3854 translations that only remove characters without re-mapping the
3855 remaining characters.
3856
Georg Brandl5cb76c12007-03-21 09:00:39 +00003857- Patch #1682205: a TypeError while unpacking an iterable is no longer
3858 masked by a generic one with the message "unpack non-sequence".
3859
Neal Norwitzaa754b72007-03-21 06:39:48 +00003860- Remove unused file Python/fmod.c.
3861
Guido van Rossum143b5642007-03-23 04:58:42 +00003862- Bug #1683368: The object.__init__() and object.__new__() methods are
3863 now stricter in rejecting excess arguments. The only time when
3864 either allows excess arguments is when it is not overridden and the
3865 other one is. For backwards compatibility, when both are
3866 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003867 warning later). Also, type.__init__() insists on the same signature
3868 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003869
Georg Brandl3ee81df2008-05-17 18:14:43 +00003870- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3871 object to complex using its __complex__() method before falling back
3872 to the __float__() method. Therefore, the functions in the cmath
3873 module now can operate on objects that define a __complex__()
3874 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003875
Georg Brandl3ee81df2008-05-17 18:14:43 +00003876- Patch #1623563: allow __class__ assignment for classes with
3877 __slots__. The old and the new class are still required to have the
3878 same slot names.

3884 ``object.__reduce_ex__()`` is called with an object that is faking
3885 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003886
Georg Brandl3ee81df2008-05-17 18:14:43 +00003887- Patch #1680015: Don't modify __slots__ tuple if it contains an

3891
Georg Brandl7b9c5552007-03-12 14:30:05 +00003892- Bug #1678647: write a newline after printing an exception in any
3893 case, even when converting the value to a string failed.
3894
Georg Brandl871f1bc2007-03-12 13:17:36 +00003895- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003896 its argument, if it exists. If not, it will work like before. This
3897 allows customizing the output of dir() in the presence of a
3898 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003899
Collin Winter276887b2007-03-12 16:11:39 +00003900- Patch #922167: Python no longer segfaults when faced with infinitely
3901 self-recursive reload() calls (as reported by bug #742342).
3902

Georg Brandl3ee81df2008-05-17 18:14:43 +00004422 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004948 time so that opening a database previously created with the DB_DUP
4949 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4950 opens. Specifically: dictionary assignment to a DB object will
4951 replace all values for a given key when the database allows
4952 duplicate values. DB users should use DB.put(k, v) when they want
4953 to store duplicates; not DB[k] = v.

4960 characters with ASCII value less than 32. Also, it correctly quotes
4961 dots only if they occur on a single line, as opposed to the previous
4962 behavior of quoting dots if they are the second character of any
4963 line.
