30 exception of canonical and is_canonical) now accept instances of int
31 and long wherever a Decimal instance is accepted, and implicitly
32 convert that argument to Decimal. Previously only some arguments
33 were converted.
34
Ronald Oussorendd25e862010-02-07 20:18:02 +000035- Issue #6003: add an argument to ``zipfile.Zipfile.writestr`` to

74 and read operations on write-only file objects. On Windows, the system C
75 library would return a bogus result; on Solaris, it was possible to crash
76 the interpreter. Patch by Stefan Krah.
77
Barry Warsawb1e66ee2010-02-05 18:45:25 +000078- Issue #7853: Normalize exceptions before they are passed to a context

92 suite_mask, and product_type.
93
Antoine Pitroue80a6a42010-01-17 12:26:20 +000094- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
95 could crash in many places because of the PyByteArray_AS_STRING() macro

108 some values large enough to cause overflow, and (4) a number of
109 flaws that could lead to incorrectly rounded results.
Mark Dickinson8efef5c2010-01-12 22:23:56 +0000110
Brett Cannon3ffa43d2010-01-14 20:00:28 +0000111- Issue #7319, #7770: Silence DeprecationWarning by default when -3 is not

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

139 specified, rather than fall through to AF_PACKET (in the `socket` module).
140 Also, raise ValueError rather than TypeError when an unknown TIPC address
141 type is specified. Patch by Brian Curtin.

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

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

Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000166- Issue #7748: Since unicode values are supported for some metadata options
167 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
168 encoded string for them. This ensure that the upload and register commands
169 send the right values to PyPI without any error.
170
R. David Murrayed44dfa2010-01-16 05:15:17 +0000171- Issue #1670765: Prevent email.generator.Generator from re-wrapping

248
Benjamin Petersonecdae192010-01-04 00:43:01 +0000249- The __complex__ method is now looked up on the class of instances to make it
250 consistent with other special methods.
251
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000252- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
253 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
254
Mark Dickinson1b34d252010-01-01 17:27:30 +0000255- Issue #5080: A number of functions and methods previously produced a
256 DeprecationWarning when passed a float argument where an integer was
257 expected. These functions and methods now raise TypeError instead.
258 The majority of the effects of this change are in the extension
259 modules, but some core functions and methods are affected: notably
260 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
261 methods.
262
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000263- Issue #7604: Deleting an unset slotted attribute did not raise an

271
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000272- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
273 used to drop the time part of the result.
274
Mark Dickinson46572832009-12-27 14:55:57 +0000275- Issue #1811: improve accuracy and cross-platform consistency for
276 true division of integers: the result of a/b is now correctly
277 rounded for ints a and b (at least on IEEE 754 platforms), and in
278 particular does not depend on the internal representation of a long.
279
Ezio Melottif84caf42009-12-24 22:25:17 +0000280- Issue #6108: unicode(exception) and str(exception) should return the same

282
Ronald Oussoren92919a62009-12-24 13:30:58 +0000283- Issue #6834: replace the implementation for the 'python' and 'pythonw'
284 executables on OSX.

427
Eric Smithc4ab8332009-11-29 17:40:57 +0000428- Issue #3382: 'F' formatting for float and complex now convert the
429 result to upper case. This only affects 'inf' and 'nan', since 'f'
430 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000431

444 on MacOSX 10.6.
445
Mark Dickinsonb678de82009-11-19 18:41:49 +0000446- Issue #7117: repr(x) for a float x returns a result based on the
447 shortest decimal string that's guaranteed to round back to x under
448 correct rounding (with round-half-to-even rounding mode).
449 Previously it gave a string based on rounding x to 17 decimal digits.
450 repr(x) for a complex number behaves similarly. On platforms where
451 the correctly-rounded strtod and dtoa code is not supported (see below),
452 repr is unchanged.
453
454- Issue #7117: On almost all platforms: float-to-string and
455 string-to-float conversions within Python are now correctly rounded.
456 Places these conversions occur include: str for floats and complex
457 numbers; the float and complex constructors; old-style and new-style
458 numeric formatting; serialization and deserialization of floats and
459 complex numbers using marshal, pickle and json; parsing of float and
460 imaginary literals in Python code; Decimal-to-float conversion.
461
462 The conversions use a Python-adapted version of David Gay's
463 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
464 functions. This code is supported on Windows, and on Unix-like
465 platforms using gcc, icc or suncc as the C compiler. There may be a
466 small number of platforms on which correct operation of this code
467 cannot be guaranteed, so the code is not used: notably, this applies
468 to platforms where the C double format is not IEEE 754 binary64, and
469 to platforms on x86 hardware where the x87 FPU is set to 64-bit
470 precision and Python's configure script is unable to determine how
471 to change the FPU precision. On these platforms conversions use the
472 platform strtod and dtoa, as before.
473
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000474- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000475 now uses the correctly-rounded string <-> float conversions
476 described above (when available), and so produces correctly rounded
477 results that will display nicely under the float repr. There are
478 two related small changes: (1) round now accepts any class with an
479 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000480 floats for the second argument), and (2) an excessively large second
481 integer argument (e.g., round(1.234, 10**100)) no longer raises an
482 exception.

623
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000624- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
625 (1) inf and nan strings with trailing whitespace were incorrectly
626 rejected; (2) parsing of strings representing infinities and nans
627 was locale aware; and (3) the interpretation of fromhex('-nan')
628 didn't match that of float('-nan').
629
Eric Smitha985a3a2009-05-05 18:26:08 +0000630- Issue #5920: For float.__format__, change the behavior with the
631 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
632 to be like 'g' but with at least one decimal point and with a
633 default precision of 12. Previously, the behavior the same but with
634 a default precision of 6. This more closely matches str(), and
635 reduces surprises when adding alignment flags to the empty
636 presentation type. This also affects the new complex.__format__ in
637 the same way.
638
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000639- Issue #5890: in subclasses of 'property' the __doc__ attribute was
640 shadowed by classtype's, even if it was None. property now
641 inserts the __doc__ into the subclass instance __dict__.
642

699 the end sys.path, for compatibility with the system install of Python.
700
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000701- Issue #4688: Add a heuristic so that tuples and dicts containing only
702 untrackable objects are not tracked by the garbage collector. This can
703 reduce the size of collections and therefore the garbage collection overhead
704 on long-running programs, depending on their particular use of datatypes.
705
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000706- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
707 improve its performance. Long divisions and remainder operations
708 are now between 50% and 150% faster.
709
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000710- Issue #4258: Make it possible to use base 2**30 instead of base
711 2**15 for the internal representation of integers, for performance
712 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
713 --enable-big-digits option to configure, which overrides the
714 default. Add sys.long_info structseq to provide information about
715 the internal format.
716
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000717- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
718 result traceback.__members__ no longer exists.)
719
Mark Dickinson6b265f12009-03-18 16:07:26 +0000720- Issue #4474: PyUnicode_FromWideChar now converts characters outside
721 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
722 and sizeof(Py_UNICODE) == 2.
723
Eric Smith6f42edb2009-03-14 11:57:26 +0000724- Issue #5237: Allow auto-numbered fields in str.format(). For
725 example: '{} {}'.format(1, 2) == '1 2'.
726
Brett Cannon6c4cff02009-03-11 04:51:06 +0000727- Issue #3652: Make the 'line' argument for warnings.showwarning() a
728 requirement. Means the DeprecationWarning from Python 2.6 can go away.
729
Eric Smithe9fb6862009-02-20 14:02:36 +0000730- Issue #5247: Improve error message when unknown format codes are
731 used when using str.format() with str, unicode, long, int, and
732 float arguments.
733
Raymond Hettinger08259e82009-02-18 23:10:19 +0000734- Running Python with the -3 option now also warns about classic division
735 for ints and longs.
736
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000737- Issue #5260: Long integers now consume less memory: average
738 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
739 on a 64-bit system.
740
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000741- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
742 rotating the object pointer by 4 bits to the right.
743
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000744- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
745 it now forces its argument to double before testing for infinity.
746
Benjamin Petersone18ef192009-01-20 14:21:16 +0000747- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
748
Georg Brandl29c6a282009-04-05 20:23:13 +0000749- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000750 were suppressing all exceptions. These include list(), filter(), map(),
751 zip(), and bytearray().
752
Benjamin Peterson596d3062009-01-19 15:42:23 +0000753- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
754 functions.
755
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000756- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

Antoine Pitrouc2f02212009-01-13 23:13:52 +0000761- Issue #4935: The overflow checking code in the expandtabs() method common
762 to str, bytes and bytearray could be optimized away by the compiler, letting
763 the interpreter segfault instead of raising an error.
764
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000765- Issue #3720: Fix a crash when an iterator modifies its class and removes its

771
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000772- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
773 collecting the oldest generation) so that allocating lots of objects without
774 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000775 Martin von Löwis at

Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000780- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
781 an existing .py counterpart, override the co_filename attributes of all
782 code objects if the original filename is obsolete (which can happen if the
783 file has been renamed, moved, or if it is accessed through different paths).
784 Patch by Ziga Seilnacht and Jean-Paul Calderone.
785
Martin v. Löwis5344c992009-01-02 20:32:55 +0000786- Issue #4075: Use OutputDebugStringW in Py_FatalError.

790
Antoine Pitrouaa687902009-01-01 14:11:22 +0000791- Issue #3680: Reference cycles created through a dict, set or deque iterator
792 did not get collected.
793
Nick Coghlan180e4002008-12-30 01:18:48 +0000794- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
795 where the tp_hash and tp_dict slots are both NULL.
796
Benjamin Peterson7af65562008-12-29 17:56:58 +0000797- Issue #4764: With io.open, IOError.filename is set when trying to open a
798 directory on POSIX systems.
799
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000800- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

804 bytearray.translate(). It was always allowed for bytes.translate().
805
Skip Montanarof205c132008-12-23 03:30:15 +0000806- Added test case to ensure attempts to read from a file opened for writing
807 fail.
808
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000809- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

822 exceptions.
823
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000824- Issue #4445: Replace "sizeof(PyStringObject)" with
825 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
826 str instances. On a typical machine this saves 3 bytes of memory
827 (on average) per string allocation.
828
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000829- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
830 interpreter to abort ("Fatal Python error: Could not reset the stack!")
831 instead of throwing a MemoryError.
832
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000833- Issue #3689: The list reversed iterator now supports __length_hint__

838
Vinay Sajip213faca2008-12-03 23:22:58 +0000839- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000840 method on file objects with closefd=False. The file descriptor is still
841 kept open but the file object behaves like a closed file. The ``FileIO``
842 object also got a new readonly attribute ``closefd``.
843
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000844- Issue #4348: Some bytearray methods returned that didn't cause any change to
845 the bytearray, returned the same bytearray instead of a copy.
846
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000847- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

861
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000862- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000863 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000865- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
866 returned a path longer than MAX_PATH. (But It's doubtful this code path is
867 really executed because I cannot move to such directory on win2k)
868
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000869- Issue #4069: When set.remove(element) is used with a set element, the element
870 is temporarily replaced with an equivalent frozenset. But the eventual
871 KeyError would always report the empty frozenset([]) as the missing key. Now
872 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000892- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
893 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
894 step. This avoids problems with counting UTF-8 bytes that ignores the effect
895 of using the replace error handler in PyUnicode_DecodeUTF8().
896
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000897- Issue #3739: The unicode-internal encoder now reports the number of characters

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

R. David Murray820b0ea2009-12-03 23:57:59 +00002125 file in the Lib/test directory, which might be read-only for the

2138
Antoine Pitrou59c44f32009-10-30 17:07:08 +00002139- Issue #7222: Make thread "reaping" more reliable so that reference
2140 leak-chasing test runs give sensible results. The previous method of
2141 reaping threads could return successfully while some Thread objects were
2142 still referenced. This also introduces a new private function:
2143 :func:`thread._count()`.
2144
R. David Murray282396f2009-10-18 21:12:37 +00002145- Issue #7151: fixed regrtest -j so that output to stderr from a test no

2147
Antoine Pitrou58d2f262009-10-10 20:52:11 +00002148- Issue #7055: test___all__ now greedily detects all modules which have an

2150
R. David Murray14dcd432009-10-14 13:58:07 +00002151- Issue #7058: Added save/restore for things like sys.argv and cwd to

2161 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

2163 skip the tests if DISPLAY is defined but can't be used.
2164
Antoine Pitrou4698d992009-05-31 14:20:14 +00002165- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running

2169 it easy to import both normal and optimised versions of modules.
2170 test_heapq and test_warnings have been adjusted to use it, tests for
2171 other modules with both C and Python implementations in the stdlib
2172 can be adjusted to use it over time.

R. David Murray41448c52009-03-31 19:57:24 +00002180- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00002181 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00002182 from test support, which does the conversion.

2280Core and Builtins
2281-----------------
2282
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002283- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2284
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002285- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2286 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2287 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2288 ``printf`` function, whereas PyString_FromFormat has an independent
2289 implementation and uses "%zd" on all platforms for size_t values.
2290 This makes a difference on win64, where ``printf`` needs "%Id" to display
2291 64bit values.
2292
Benjamin Peterson97179b02008-09-09 20:55:01 +00002293- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2294 error.
2295
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002296- Issue #3777: long() applied to a float object now always return a long
2297 object; previously an int would be returned for small values. the __long__
2298 method is allowed to return either an int or a long, but the behaviour of
2299 float objects should not change to respect backward compatibility.
2300
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002301- Issue #3751: str.rpartition would perform a left-partition when called with
2302 a unicode argument.
2303
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002304- Issue #3683: Fix compilation when --without-threads is given.
2305
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002306- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002307 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002308 was correctly parsed but parsing of subsequent arguments failed.
2309
Vinay Sajip35e3b032008-09-01 14:33:59 +00002310- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002311 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2312 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2313 when given a tuple of classes as second argument, were looking up
2314 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2315 type object.
2316
Neal Norwitz18aa3882008-08-24 05:04:52 +00002317- Fix crashes on memory allocation failure found with failmalloc.
2318
2319- Fix memory leaks found with valgrind and update suppressions file.
2320
2321- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2322
2323- Fix problem using wrong name in decimal module reported by pychecker.
2324
Christian Heimes7d4c3172008-08-22 19:47:25 +00002325- Silenced another compiler warning about a used but not defined
2326 function 'stringlib_contains_obj'.
2327
Benjamin Peterson712ee922008-08-24 18:10:20 +00002328- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2329 ``__delslice__``.
2330
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002331- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2332 library targets in the Makefile.
2333
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002334- Issue #1204: The configure script now tests for additional libraries
2335 that may be required when linking against readline. This fixes issues
2336 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
2337

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00002346- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
2347 stack usage in the case of deeply nested objects.
2348
Guido van Rossume3c4fd92008-09-10 14:27:00 +00002349- Issue #3629: Fix sre "bytecode" validator for an end case.

2352
Nick Coghland2e09382008-09-11 12:11:06 +00002353- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
2354 silent misbehaviour when a single instance is nested in multiple

2356
Vinay Sajip844f7412008-09-09 13:42:08 +00002357- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
2358
Nick Coghland2e09382008-09-11 12:11:06 +00002359- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002360 return a list or None rather than a custom object.
2361
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002362- Issue #1638033: Cookie.Morsel gained the httponly attribute.
2363

2369 its symbolic link.
2370
Vinay Sajip65d66e12008-09-04 07:31:21 +00002371- Issue #3772: Fixed regression problem in StreamHandler.emit().

2386 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2387 for catch_warnings() also led to an improvement in the raising of a
2388 DeprecationWarning related to warnings.warn_explicit().
2389
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002390- The deprecation warnings for the old camelCase threading API were removed.

2418 exploitation of poor argument checking.
2419
Gerhard Häringef2276b2008-09-12 13:54:06 +00002420- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002454What's New in Python 2.6 beta 3?
2455================================
2456
Barry Warsaw07a4a382008-08-21 01:15:08 +00002457*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002458
2459Core and Builtins
2460-----------------
2461
Guido van Rossumf8402962008-08-20 15:01:50 +00002462- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2463 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2464 extensions do not automatically benefit from the class attribute
2465 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2466 to their tp_flags field if they care. This is a backwards
2467 compatibility feature; in 3.0, all types will use the cache by
2468 default.
2469
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002470- Keyword arguments can now follow starred arguments. (``f(a, *args,
2471 keyword=23)`` is now valid syntax.)
2472
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002473- ctypes function pointers that are COM methods have a boolean True
2474 value again.
2475
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002476- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2477 by denying s# to parse objects that have a releasebuffer procedure,
2478 and introducing s*.
2479
Georg Brandl1e13ea92008-08-11 09:07:59 +00002480- Issue #3537: Fix an assertion failure when an empty but presized dict
2481 object was stored in the freelist.
2482
Mark Dickinsonb6467572008-08-04 21:30:09 +00002483- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2484 ValueError consistently across platforms.
2485
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002486- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2487 (64bit Unix, for example), unichr() would truncate its argument and return
2488 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2489
Neal Norwitze7d8be82008-07-31 17:17:14 +00002490- Apply security patches from Apple.
2491
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002492- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2493 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2494
Antoine Pitrou92f82162008-07-25 22:22:08 +00002495- Issue #1819: function calls with several named parameters are now on
2496 average 35% faster (as measured by pybench).
2497
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002498- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2499 the python debugger steps into a class statement: the free variables (local
2500 variables defined in an outer scope) would be deleted from the outer scope.
2501
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002502- Issue #2620: Overflow checking when allocating or reallocating memory
2503 was not always being done properly in some python types and extension
2504 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2505 all been updated to perform better checks and places in the code that
2506 would previously leak memory on the error path when such an allocation
2507 failed have been fixed.
2508

2510-------
2511
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002512- Issue #3612: Added some missing basic types in ctypes.wintypes.
2513
Benjamin Petersone977ad42008-08-20 01:42:01 +00002514- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2515 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2516
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002517- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2518 version reported by these tools does not necessarily follow the python
2519 version numbering scheme, so the module is less strict when parsing it.
2520
Nick Coghlanf70385a2008-08-18 12:42:46 +00002521- Issue #2235: Added Py3k warnings for types which will become unhashable
2522 under the stricter __hash__ inheritance rules in 3.0. Several types
2523 which did not meet the rules for hash invariants and were already
2524 unhashable in 3.0 have now been explicitly flagged as unhashable in
2525 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2526 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2527
Brett Cannon88f801d2008-08-18 00:46:22 +00002528- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2529 imported into the module but exposed as part of the module's API.
2530
Brett Cannon7b96f072008-08-18 00:41:11 +00002531- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2532
Brett Cannon46225e72008-08-18 00:36:52 +00002533- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2536
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002537- Issue #3575: Incremental decoder's decode function now takes bytearray
2538 by using 's*' instead of 't#'.
2539
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002540- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002541 fails unicode conversion on 2nd parameter. (windows only)
2542
Facundo Batista94f243a2008-08-17 03:38:39 +00002543- Issue 2464. urllib2 now supports a malformation in the URL received
2544 in a redirect.
2545
Brett Cannonabe423e2008-08-16 21:47:07 +00002546- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002547 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002548
Facundo Batistaeb90b782008-08-16 14:44:07 +00002549- Issue #2776: fixed small issue when handling an URL with double slash
2550 after a 302 response in the case of not going through a proxy.
2551
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002552- Issue #2676: in the email package, content-type parsing was hanging on
2553 pathological input because of quadratic or exponential behaviour of a
2554 regular expression.
2555
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002556- Issue #3476: binary buffered reading through the new "io" library is now
2557 thread-safe.
2558
Brett Cannonbf3157b2008-08-14 05:00:03 +00002559- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2560 since mimetools itself is deprecated. Because modules are cached, all
2561 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2562
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002563- Issue #3134: shutil referenced undefined WindowsError symbol.
2564
Robert Schuppenies14646332008-08-10 11:01:53 +00002565- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2566 menu entries were not deleted.

Benjamin Peterson01a24322008-07-28 23:35:27 +00002596- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002597 asking for a specific length. This problem only affected files opened
2598 using the new "io" module, not the built-in open() function.

2625 mode 0600 rather than 000 under Unix.
2626
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002627- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2640 interaction with the tp_hash slot (added in 2.6b2) are now documented
2641
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002642- Issue #643841: The language reference now provides more detailed
2643 coverage of the lookup process for special methods. The disclaimers
2644 regarding lack of coverage of new-style classes have also been

2654-----------------
2655
Georg Brandl3e483f62008-07-16 22:57:41 +00002656- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2657 its methods now allow for items objects that can be converted to
2658 an integer using operator.index().
2659
Mark Dickinson64b7e502008-07-16 09:40:03 +00002660- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2661 produced a ValueError instead of giving the correct float.
2662
Eric Smitha5fa5a22008-07-16 00:11:49 +00002663- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2664 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2665
Mark Dickinson7103aa42008-07-15 19:08:33 +00002666- Issue #3008: the float type has a new instance method 'float.hex'
2667 and a new class method 'float.fromhex' to convert floating-point
2668 numbers to and from hexadecimal strings, respectively.
2669
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002670- Issue #2235: __hash__ is once again inherited by default. To allow
2671 collections.Hashable to remain meaningful in the presence of the
2672 default hash implementation (object.__hash__), it is now possible
2673 to explicit block inheritance of hash by setting __hash__=None at
2674 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2675 level.
2676
Nick Coghlanb028f502008-07-13 14:52:36 +00002677- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2678 the parent module cannot be found while performing an absolute import.
2679 This means that an incorrectly defined __package__ attribute will
2680 now only prevent relative imports in that module rather than causing
2681 all imports from that module to fail.
2682
Nick Coghlan14ff9942008-07-08 14:21:42 +00002683- Issue #2517: Allow unicode messages in Exceptions again by correctly

2693 another thread's dictionary.
2694
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002695- Issue #3004: Minor change to slice.indices(): the start and stop
2696 arguments are now treated identically, making the behaviour easier
2697 to describe and understand. For example, slice(None, -10,
2698 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2699 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2700 10, -1).
2701
Georg Brandl278fc502008-07-19 12:46:12 +00002702- Issue #3219: Calling a function with repeated keyword arguments,
2703 f(a=2, a=23), would not cause a syntax error. This was a regression
2704 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002705
Georg Brandl278fc502008-07-19 12:46:12 +00002706- Issue #2862: Make int and float freelist management consistent with
2707 other freelists. Changes their CompactFreeList apis into

2714 api functions without holding the GIL, which could lead to a fatal
2715 error when they failed.
2716
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002717- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002742- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2743 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002744 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002745 content-length. The problem had been corrected in the 2.4 branch, but never
2746 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002761- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3149
Brett Cannonb61d8012008-05-11 23:39:04 +00003150- ``Lib/lib-old`` is now added to sys.path.
3151
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003152- On MacOS X it is now possible to install the framework in 64-bit
3153 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003154 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003155
3156 This is controlled by the configure argument ``--with-universal-archs``:
3157
3158 - ``--with-universal-archs=all``: install 4-way universal
3159
3160 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3161
3162 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3163
3164 This option should be used in combination with ``--enable-universalsdk=``.
3165
3166 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 +00003175
3176- The PyString functions have been renamed to PyBytes. A batch of
3177 defines were added so that the linker still sees the original
3178 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003216- Issue #1631171: Re-implement the 'warnings' module in C (the
3217 original Python code has been kept as backup). This will allow for
3218 using the 'warning's machinery in such places as the parser where
3219 use of pure Python code is not possible. Both the ``showarning()``
3220 and ``formatwarning()`` gain an optional 'line' argument which is
3221 not called by default for backwards-compatibility reasons. Setting
3222 ``warnings.showwarning()`` to an implementation that lacks support
3223 for the ``line`` argument will raise a DeprecationWarning.

3247
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003248- The getpass module has been improved on Unix. It now uses /dev/tty
3249 by default and uses stderr instead of stdout. A GetPassWarning is
3250 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003265- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003266 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003286- Issue #2550: The approach used by client/server code for obtaining
3287 ports to listen on in network-oriented tests has been refined in an
3288 effort to facilitate running multiple instances of the entire
3289 regression test suite in parallel without issue.
3290 test_support.bind_port() has been fixed such that it will always
3291 return a unique port -- which wasn't always the case with the
3292 previous implementation, especially if socket options had been set
3293 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3294 new implementation of bind_port() will actually raise an exception
3295 if it is passed an AF_INET/SOCK_STREAM socket with either the
3296 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3297 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3298 the socket it's been passed. This currently only applies to
3299 Windows. This option prevents any other sockets from binding to the
3300 host/port we've bound to, thus removing the possibility of the
3301 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3302 when a second SOCK_STREAM socket binds and accepts to a host/port
3303 that's already been bound by another socket. The optional preferred
3304 port parameter to bind_port() has been removed. Under no
3305 circumstances should tests be hard coding ports!
3306
3307 test_support.find_unused_port() has also been introduced, which will
3308 pass a temporary socket object to bind_port() in order to obtain an
3309 unused port. The temporary socket object is then closed and
3310 deleted, and the port is returned. This method should only be used
3311 for obtaining an unused port in order to pass to an external program
3312 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3313 a parameter to a server-oriented class that doesn't give you direct
3314 access to the underlying socket used.
3315
3316 Finally, test_support.HOST has been introduced, which should be used
3317 for the host argument of any relevant socket calls (i.e. bind and
3318 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003319
3320 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003321 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003322 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3323 test_asynchat and test_socket_ssl.
3324
Georg Brandl3ee81df2008-05-17 18:14:43 +00003325 It is now possible for multiple instances of the regression test
3326 suite to run in parallel without issue.

3593-----------------
3594
Fred Drakea8ee94b2008-03-01 02:45:07 +00003595- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003596 644. The mode is now inherited from the py file.

3599
3600- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003601
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003602- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003603 issue 215555 for a discussion.
3604
Eric Smitha73fbe72008-02-23 03:09:44 +00003605- Added the future_builtins module, which contains hex() and oct().
3606 These are the PEP 3127 version of these functions, designed to be
3607 compatible with the hex() and oct() builtins from Python 3.0. They
3608 differ slightly in their output formats from the existing, unchanged
3609 Python 2.6 builtins. The expected usage of the future_builtins
3610 module is:
3611 from future_builtins import hex, oct
3612
Eric Smith7ef40bf2008-02-20 23:34:22 +00003613- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3614 exponents for exponents with absolute value < 100. Follows C99
3615 standard. This is a change on Windows, which would use 3 digits.
3616 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3617 so that any alterations it does to the resulting string will be
3618 available in stringlib/formatter.h (for float.__format__).
3619
Eric Smith5a3c1352008-02-19 13:21:56 +00003620- Implemented PEP 3101, Advanced String Formatting. This adds a new
3621 builtin format(); a format() method for str and unicode; a
3622 __format__() method to object, str, unicode, int, long, float, and
3623 datetime; the class string.Formatter; and the C API
3624 PyObject_Format().
3625
Georg Brandl3ee81df2008-05-17 18:14:43 +00003626- Fixed several potential crashes, all caused by specially crafted
3627 __del__ methods exploiting objects in temporarily inconsistent
3628 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003629
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003630- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003631 prevent a possible crash: an Abstract Base Class would try to access
3632 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003633

Georg Brandl3ee81df2008-05-17 18:14:43 +00003637- Clear all free lists during a gc.collect() of the highest generation
3638 in order to allow pymalloc to free more arenas. Python may give back
3639 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003640
Georg Brandl3ee81df2008-05-17 18:14:43 +00003641- Issue #2045: Fix an infinite recursion triggered when printing a
3642 subclass of collections.defaultdict, if its default_factory is set
3643 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003644
Christian Heimesf75dbef2008-02-08 00:11:31 +00003645- Fixed a minor memory leak in dictobject.c. The content of the free
3646 list was not freed on interpreter shutdown.
3647
Georg Brandl3ee81df2008-05-17 18:14:43 +00003648- Limit free list of method and builtin function objects to 256
3649 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003650
Georg Brandl3ee81df2008-05-17 18:14:43 +00003651- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3652 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003653 to compact the internal free lists of pre-allocted ints and floats.
3654
Georg Brandl3ee81df2008-05-17 18:14:43 +00003655- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3656 calls. Python expected the return type int but the fork familie
3657 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003658
Georg Brandl3ee81df2008-05-17 18:14:43 +00003659- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3660 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003661
Georg Brandl3ee81df2008-05-17 18:14:43 +00003662- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3663 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003664
Georg Brandl3ee81df2008-05-17 18:14:43 +00003665- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3666 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003667
Georg Brandl3ee81df2008-05-17 18:14:43 +00003668- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3669 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003670
Georg Brandl3ee81df2008-05-17 18:14:43 +00003671- Patch #1473257: generator objects gain a gi_code attribute. This is
3672 the same object as the func_code attribute of the function that
3673 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003674
Georg Brandl3ee81df2008-05-17 18:14:43 +00003675- Issue #1920: "while 0" statements were completely removed by the
3676 compiler, even in the presence of an "else" clause, which is
3677 supposed to be run when the condition is false. Now the compiler
3678 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003679
Guido van Rossumeead05f2008-01-24 18:21:02 +00003680- A few crashers fixed: weakref_in_del.py (issue #1377858);
3681 loosing_dict_ref.py (issue #1303614, test67.py);
3682 borrowed_ref_[34].py (not in tracker).
3683
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003684- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003685 suppressed while an extension is loaded by calling SetErrorMode in
3686 dynload_win.c. The error is still reported properly.
3687
Georg Brandl3ee81df2008-05-17 18:14:43 +00003688- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003689 several extension methods and modules do not work without unicode
3690 support.
3691
Georg Brandl26543b12008-01-21 18:36:51 +00003692- Issue #1882: when compiling code from a string, encoding cookies in the
3693 second line of code were not always recognized correctly.
3694
Georg Brandl14404b62008-01-19 19:27:05 +00003695- Issue #1679: "0x" was taken as a valid integer literal.
3696
Georg Brandl6caad7d2008-01-26 14:19:22 +00003697- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003698 added.
3699
Christian Heimesc94e2b52008-01-14 04:13:37 +00003700- sys.float_info / PyFloat_GetInfo: The floating point information
3701 object was converted from a dict to a specialized structseq object.
3702
Georg Brandl3ee81df2008-05-17 18:14:43 +00003703- Patch #1816: Added sys.flags structseq. It exposes the status of
3704 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003705
Georg Brandl3ee81df2008-05-17 18:14:43 +00003706- Objects/structseq.c: Implemented new structseq representation. The
3707 patch makes structseqs (e.g. the return value of os.stat) more
3708 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003709
Georg Brandl3ee81df2008-05-17 18:14:43 +00003710- Patch #1700288: added a type attribute cache that caches method
3711 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003712
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003713- Bug #1776: __import__() no longer accepts filenames on any platform.
3714 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00003716- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3717
Georg Brandl3ee81df2008-05-17 18:14:43 +00003718- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3719 envvar and sys.dont_write_bytecode attribute. All these can be set
3720 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003721
Georg Brandl3ee81df2008-05-17 18:14:43 +00003722- Improve some exception messages when Windows fails to load an
3723 extension module. Now we get for example '%1 is not a valid Win32
3724 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003725

Christian Heimes0a8143f2007-12-18 23:22:54 +00003731- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003732 and INF. float("nan"), float("inf") and float("-inf") now work on
3733 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003734
Georg Brandl3ee81df2008-05-17 18:14:43 +00003735- Compiler now generates simpler and faster code for dictionary
3736 literals. The oparg for BUILD_MAP now indicates an estimated
3737 dictionary size. There is a new opcode, STORE_MAP, for adding
3738 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003767- Patch #1739468: Directories and zipfiles containing a __main__.py
3768 file can now be directly executed by passing their name to the
3769 interpreter. The directory/zipfile is automatically inserted as the
3770 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003771
Georg Brandl3ee81df2008-05-17 18:14:43 +00003772- Issue #1265: Fix a problem with sys.settrace, if the tracing
3773 function uses a generator expression when at the same time the
3774 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003775
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003776- sets and frozensets now have an isdisjoint() method.
3777

3779
Neal Norwitz44f326e2007-10-05 05:29:17 +00003780- Fix warnings found by the new version of the Coverity checker.
3781
Georg Brandl3ee81df2008-05-17 18:14:43 +00003782- The enumerate() builtin function is no longer bounded to sequences
3783 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3784 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003785
Georg Brandl3ee81df2008-05-17 18:14:43 +00003786- Issue #1686386: Tuple's tp_repr did not take into account the
3787 possibility of having a self-referential tuple, which is possible
3788 from C code. Nor did object's tp_str consider that a type's tp_str
3789 could do something that could lead to an inifinite recursion.
3790 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3791 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003792
Georg Brandl3ee81df2008-05-17 18:14:43 +00003793- Issue #1164: It was possible to trigger deadlock when using the
3794 'print' statement to write to a file since the GIL was not released
3795 as needed. Now PyObject_Print() does the right thing along with
3796 various tp_print implementations of the built-in types and those in
3797 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003798
Georg Brandl3ee81df2008-05-17 18:14:43 +00003799- Issue #1147: Exceptions were directly allowing string exceptions in
3800 their throw() method even though string exceptions no longer
3801 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003802
Georg Brandl3ee81df2008-05-17 18:14:43 +00003803- Issue #1096: Prevent a segfault from getting the repr of a very
3804 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003805
Brett Cannon1e534b52007-09-07 04:18:30 +00003806- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003807 PyObject_Call() never calling back out to Python code to trigger
3808 recursion depth updates/checks. Required the creation of a static
3809 RuntimeError instance in case normalizing an exception put the
3810 recursion check value past its limit. Fixes crashers
3811 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003812
Georg Brandl3ee81df2008-05-17 18:14:43 +00003813- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003826- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827 __*__ attributes. (Some already existed, e.g., __doc__ and
3828 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003829
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003830- Add -3 option to the interpreter to warn about features that are
3831 deprecated and will be changed/removed in Python 3.0.
3832
Georg Brandl2134e752007-05-21 20:34:16 +00003833- Patch #1686487: you can now pass any mapping after '**' in function
3834 calls.
3835
Collin Winter62903052007-05-18 23:11:24 +00003836- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837 "except E as target:". This is to provide forwards compatibility
3838 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003839
Brett Cannon229cee22007-05-05 01:34:02 +00003840- Deprecate BaseException.message as per PEP 352.
3841
Georg Brandl3ee81df2008-05-17 18:14:43 +00003842- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003843 inherited from a builtin base.
3844
Vinay Sajip8549ce32007-05-06 17:53:37 +00003845- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003846 setting a plain string, ie don't expand to single letter identifiers.
3847
Raymond Hettinger13936692007-04-11 18:40:58 +00003848- Request #1191699: Slices can now be pickled.
3849
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003850- Request #1193128: str.translate() now allows a None argument for
3851 translations that only remove characters without re-mapping the
3852 remaining characters.
3853
Georg Brandl5cb76c12007-03-21 09:00:39 +00003854- Patch #1682205: a TypeError while unpacking an iterable is no longer
3855 masked by a generic one with the message "unpack non-sequence".
3856
Neal Norwitzaa754b72007-03-21 06:39:48 +00003857- Remove unused file Python/fmod.c.
3858
Guido van Rossum143b5642007-03-23 04:58:42 +00003859- Bug #1683368: The object.__init__() and object.__new__() methods are
3860 now stricter in rejecting excess arguments. The only time when
3861 either allows excess arguments is when it is not overridden and the
3862 other one is. For backwards compatibility, when both are
3863 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003864 warning later). Also, type.__init__() insists on the same signature
3865 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003866
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3868 object to complex using its __complex__() method before falling back
3869 to the __float__() method. Therefore, the functions in the cmath
3870 module now can operate on objects that define a __complex__()
3871 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003872
Georg Brandl3ee81df2008-05-17 18:14:43 +00003873- Patch #1623563: allow __class__ assignment for classes with
3874 __slots__. The old and the new class are still required to have the
3875 same slot names.

3881 ``object.__reduce_ex__()`` is called with an object that is faking
3882 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003883
Georg Brandl3ee81df2008-05-17 18:14:43 +00003884- Patch #1680015: Don't modify __slots__ tuple if it contains an

3888
Georg Brandl7b9c5552007-03-12 14:30:05 +00003889- Bug #1678647: write a newline after printing an exception in any
3890 case, even when converting the value to a string failed.
3891
Georg Brandl871f1bc2007-03-12 13:17:36 +00003892- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003893 its argument, if it exists. If not, it will work like before. This
3894 allows customizing the output of dir() in the presence of a
3895 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003897- Patch #922167: Python no longer segfaults when faced with infinitely
3898 self-recursive reload() calls (as reported by bug #742342).
3899

Georg Brandl4e933132006-09-06 20:05:58 +00004010- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004419 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004945 time so that opening a database previously created with the DB_DUP
4946 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4947 opens. Specifically: dictionary assignment to a DB object will
4948 replace all values for a given key when the database allows
4949 duplicate values. DB users should use DB.put(k, v) when they want
4950 to store duplicates; not DB[k] = v.

4957 characters with ASCII value less than 32. Also, it correctly quotes
4958 dots only if they occur on a single line, as opposed to the previous
4959 behavior of quoting dots if they are the second character of any
4960 line.
