71 and read operations on write-only file objects. On Windows, the system C
72 library would return a bogus result; on Solaris, it was possible to crash
73 the interpreter. Patch by Stefan Krah.
74
Barry Warsawb1e66ee2010-02-05 18:45:25 +000075- Issue #7853: Normalize exceptions before they are passed to a context

105 some values large enough to cause overflow, and (4) a number of
106 flaws that could lead to incorrectly rounded results.

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

164 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
165 encoded string for them. This ensure that the upload and register commands
166 send the right values to PyPI without any error.
167
R. David Murrayed44dfa2010-01-16 05:15:17 +0000168- Issue #1670765: Prevent email.generator.Generator from re-wrapping

244-----------------
245
Benjamin Petersonecdae192010-01-04 00:43:01 +0000246- The __complex__ method is now looked up on the class of instances to make it
247 consistent with other special methods.
248
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000249- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
250 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
251
Mark Dickinson1b34d252010-01-01 17:27:30 +0000252- Issue #5080: A number of functions and methods previously produced a
253 DeprecationWarning when passed a float argument where an integer was
254 expected. These functions and methods now raise TypeError instead.
255 The majority of the effects of this change are in the extension
256 modules, but some core functions and methods are affected: notably
257 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
258 methods.
259
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000260- Issue #7604: Deleting an unset slotted attribute did not raise an

268
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000269- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
270 used to drop the time part of the result.
271
Mark Dickinson46572832009-12-27 14:55:57 +0000272- Issue #1811: improve accuracy and cross-platform consistency for
273 true division of integers: the result of a/b is now correctly
274 rounded for ints a and b (at least on IEEE 754 platforms), and in
275 particular does not depend on the internal representation of a long.
276
Ezio Melottif84caf42009-12-24 22:25:17 +0000277- Issue #6108: unicode(exception) and str(exception) should return the same
278 message when only __str__ (and not __unicode__) is overridden in the subclass.
279
Ronald Oussoren92919a62009-12-24 13:30:58 +0000280- Issue #6834: replace the implementation for the 'python' and 'pythonw'
281 executables on OSX.
282

284 ``arch -ppc python`` will start a universal binary version of python
285 in PPC mode (unlike previous releases).

423 with invalid values.
424
Eric Smithc4ab8332009-11-29 17:40:57 +0000425- Issue #3382: 'F' formatting for float and complex now convert the
426 result to upper case. This only affects 'inf' and 'nan', since 'f'
427 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000428

433 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
434 requested 120 significant digits instead.
435

441 on MacOSX 10.6.
442
Mark Dickinsonb678de82009-11-19 18:41:49 +0000443- Issue #7117: repr(x) for a float x returns a result based on the
444 shortest decimal string that's guaranteed to round back to x under
445 correct rounding (with round-half-to-even rounding mode).
446 Previously it gave a string based on rounding x to 17 decimal digits.
447 repr(x) for a complex number behaves similarly. On platforms where
448 the correctly-rounded strtod and dtoa code is not supported (see below),
449 repr is unchanged.
450
451- Issue #7117: On almost all platforms: float-to-string and
452 string-to-float conversions within Python are now correctly rounded.
453 Places these conversions occur include: str for floats and complex
454 numbers; the float and complex constructors; old-style and new-style
455 numeric formatting; serialization and deserialization of floats and
456 complex numbers using marshal, pickle and json; parsing of float and
457 imaginary literals in Python code; Decimal-to-float conversion.
458
459 The conversions use a Python-adapted version of David Gay's
460 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
461 functions. This code is supported on Windows, and on Unix-like
462 platforms using gcc, icc or suncc as the C compiler. There may be a
463 small number of platforms on which correct operation of this code
464 cannot be guaranteed, so the code is not used: notably, this applies
465 to platforms where the C double format is not IEEE 754 binary64, and
466 to platforms on x86 hardware where the x87 FPU is set to 64-bit
467 precision and Python's configure script is unable to determine how
468 to change the FPU precision. On these platforms conversions use the
469 platform strtod and dtoa, as before.
470
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000471- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000472 now uses the correctly-rounded string <-> float conversions
473 described above (when available), and so produces correctly rounded
474 results that will display nicely under the float repr. There are
475 two related small changes: (1) round now accepts any class with an
476 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000477 floats for the second argument), and (2) an excessively large second
478 integer argument (e.g., round(1.234, 10**100)) no longer raises an
479 exception.

620
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000621- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
622 (1) inf and nan strings with trailing whitespace were incorrectly
623 rejected; (2) parsing of strings representing infinities and nans
624 was locale aware; and (3) the interpretation of fromhex('-nan')
625 didn't match that of float('-nan').
626
Eric Smitha985a3a2009-05-05 18:26:08 +0000627- Issue #5920: For float.__format__, change the behavior with the
628 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
629 to be like 'g' but with at least one decimal point and with a
630 default precision of 12. Previously, the behavior the same but with
631 a default precision of 6. This more closely matches str(), and
632 reduces surprises when adding alignment flags to the empty
633 presentation type. This also affects the new complex.__format__ in
634 the same way.
635
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000636- Issue #5890: in subclasses of 'property' the __doc__ attribute was
637 shadowed by classtype's, even if it was None. property now
638 inserts the __doc__ into the subclass instance __dict__.
639
Antoine Pitrou653dece2009-05-04 18:32:32 +0000640- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

696 the end sys.path, for compatibility with the system install of Python.
697
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000698- Issue #4688: Add a heuristic so that tuples and dicts containing only
699 untrackable objects are not tracked by the garbage collector. This can
700 reduce the size of collections and therefore the garbage collection overhead
701 on long-running programs, depending on their particular use of datatypes.
702
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000703- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
704 improve its performance. Long divisions and remainder operations
705 are now between 50% and 150% faster.
706
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000707- Issue #4258: Make it possible to use base 2**30 instead of base
708 2**15 for the internal representation of integers, for performance
709 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
710 --enable-big-digits option to configure, which overrides the
711 default. Add sys.long_info structseq to provide information about
712 the internal format.
713
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000714- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
715 result traceback.__members__ no longer exists.)
716
Mark Dickinson6b265f12009-03-18 16:07:26 +0000717- Issue #4474: PyUnicode_FromWideChar now converts characters outside
718 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

723
Brett Cannon6c4cff02009-03-11 04:51:06 +0000724- Issue #3652: Make the 'line' argument for warnings.showwarning() a
725 requirement. Means the DeprecationWarning from Python 2.6 can go away.
726
Eric Smithe9fb6862009-02-20 14:02:36 +0000727- Issue #5247: Improve error message when unknown format codes are

729 float arguments.
730
Raymond Hettinger08259e82009-02-18 23:10:19 +0000731- Running Python with the -3 option now also warns about classic division
732 for ints and longs.
733
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000734- Issue #5260: Long integers now consume less memory: average
735 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
736 on a 64-bit system.
737
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000738- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
739 rotating the object pointer by 4 bits to the right.

745
Georg Brandl29c6a282009-04-05 20:23:13 +0000746- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000747 were suppressing all exceptions. These include list(), filter(), map(),
748 zip(), and bytearray().
749
Benjamin Peterson596d3062009-01-19 15:42:23 +0000750- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

760 the interpreter segfault instead of raising an error.
761
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000762- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000769- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
770 collecting the oldest generation) so that allocating lots of objects without
771 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000772 Martin von Löwis at

Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000777- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
778 an existing .py counterpart, override the co_filename attributes of all
779 code objects if the original filename is obsolete (which can happen if the
780 file has been renamed, moved, or if it is accessed through different paths).
781 Patch by Ziga Seilnacht and Jean-Paul Calderone.

790
Nick Coghlan180e4002008-12-30 01:18:48 +0000791- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
792 where the tp_hash and tp_dict slots are both NULL.
793
Benjamin Peterson7af65562008-12-29 17:56:58 +0000794- Issue #4764: With io.open, IOError.filename is set when trying to open a

802
Skip Montanarof205c132008-12-23 03:30:15 +0000803- Added test case to ensure attempts to read from a file opened for writing
804 fail.
805

819 exceptions.
820
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000821- Issue #4445: Replace "sizeof(PyStringObject)" with
822 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
823 str instances. On a typical machine this saves 3 bytes of memory
824 (on average) per string allocation.
825
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000826- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
827 interpreter to abort ("Fatal Python error: Could not reset the stack!")
828 instead of throwing a MemoryError.
829
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000830- Issue #3689: The list reversed iterator now supports __length_hint__

Vinay Sajip213faca2008-12-03 23:22:58 +0000836- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000837 method on file objects with closefd=False. The file descriptor is still
838 kept open but the file object behaves like a closed file. The ``FileIO``
839 object also got a new readonly attribute ``closefd``.
840
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000841- Issue #4348: Some bytearray methods returned that didn't cause any change to

858
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000859- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000860 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000862- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
863 returned a path longer than MAX_PATH. (But It's doubtful this code path is
864 really executed because I cannot move to such directory on win2k)
865
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000866- Issue #4069: When set.remove(element) is used with a set element, the element
867 is temporarily replaced with an equivalent frozenset. But the eventual
868 KeyError would always report the empty frozenset([]) as the missing key. Now
869 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000889- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
890 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
891 step. This avoids problems with counting UTF-8 bytes that ignores the effect
892 of using the replace error handler in PyUnicode_DecodeUTF8().
893
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000894- Issue #3739: The unicode-internal encoder now reports the number of characters

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

R. David Murray820b0ea2009-12-03 23:57:59 +00002122 file in the Lib/test directory, which might be read-only for the

2135
Antoine Pitrou59c44f32009-10-30 17:07:08 +00002136- Issue #7222: Make thread "reaping" more reliable so that reference
2137 leak-chasing test runs give sensible results. The previous method of
2138 reaping threads could return successfully while some Thread objects were
2139 still referenced. This also introduces a new private function:
2140 :func:`thread._count()`.
2141
R. David Murray282396f2009-10-18 21:12:37 +00002142- Issue #7151: fixed regrtest -j so that output to stderr from a test no

2144
Antoine Pitrou58d2f262009-10-10 20:52:11 +00002145- Issue #7055: test___all__ now greedily detects all modules which have an

2147
R. David Murray14dcd432009-10-14 13:58:07 +00002148- Issue #7058: Added save/restore for things like sys.argv and cwd to

2158 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

2160 skip the tests if DISPLAY is defined but can't be used.
2161
Antoine Pitrou4698d992009-05-31 14:20:14 +00002162- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running

2166 it easy to import both normal and optimised versions of modules.
2167 test_heapq and test_warnings have been adjusted to use it, tests for
2168 other modules with both C and Python implementations in the stdlib
2169 can be adjusted to use it over time.

R. David Murray41448c52009-03-31 19:57:24 +00002177- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00002178 that should cause a test to be skipped are now done using import_module

2277Core and Builtins
2278-----------------
2279
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002280- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2281
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002282- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2283 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2284 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2285 ``printf`` function, whereas PyString_FromFormat has an independent
2286 implementation and uses "%zd" on all platforms for size_t values.
2287 This makes a difference on win64, where ``printf`` needs "%Id" to display
2288 64bit values.
2289
Benjamin Peterson97179b02008-09-09 20:55:01 +00002290- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2291 error.
2292
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002293- Issue #3777: long() applied to a float object now always return a long
2294 object; previously an int would be returned for small values. the __long__
2295 method is allowed to return either an int or a long, but the behaviour of
2296 float objects should not change to respect backward compatibility.
2297
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002298- Issue #3751: str.rpartition would perform a left-partition when called with
2299 a unicode argument.
2300
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002301- Issue #3683: Fix compilation when --without-threads is given.
2302
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002303- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002304 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002305 was correctly parsed but parsing of subsequent arguments failed.
2306
Vinay Sajip35e3b032008-09-01 14:33:59 +00002307- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002308 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2309 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2310 when given a tuple of classes as second argument, were looking up
2311 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2312 type object.
2313
Neal Norwitz18aa3882008-08-24 05:04:52 +00002314- Fix crashes on memory allocation failure found with failmalloc.
2315
2316- Fix memory leaks found with valgrind and update suppressions file.
2317
2318- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2319
2320- Fix problem using wrong name in decimal module reported by pychecker.
2321
Christian Heimes7d4c3172008-08-22 19:47:25 +00002322- Silenced another compiler warning about a used but not defined
2323 function 'stringlib_contains_obj'.
2324
Benjamin Peterson712ee922008-08-24 18:10:20 +00002325- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2326 ``__delslice__``.
2327
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002328- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2329 library targets in the Makefile.
2330
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002331- Issue #1204: The configure script now tests for additional libraries
2332 that may be required when linking against readline. This fixes issues
2333 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
2334
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00002335C-API
2336-----

2355
Nick Coghland2e09382008-09-11 12:11:06 +00002356- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002357 return a list or None rather than a custom object.
2358
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002359- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2383 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2384 for catch_warnings() also led to an improvement in the raising of a
2385 DeprecationWarning related to warnings.warn_explicit().
2386
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002387- The deprecation warnings for the old camelCase threading API were removed.

2415 exploitation of poor argument checking.
2416
Gerhard Häringef2276b2008-09-12 13:54:06 +00002417- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002451What's New in Python 2.6 beta 3?
2452================================
2453
Barry Warsaw07a4a382008-08-21 01:15:08 +00002454*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002455
2456Core and Builtins
2457-----------------
2458
Guido van Rossumf8402962008-08-20 15:01:50 +00002459- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2460 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2461 extensions do not automatically benefit from the class attribute
2462 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2463 to their tp_flags field if they care. This is a backwards
2464 compatibility feature; in 3.0, all types will use the cache by
2465 default.
2466
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002467- Keyword arguments can now follow starred arguments. (``f(a, *args,
2468 keyword=23)`` is now valid syntax.)
2469
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002470- ctypes function pointers that are COM methods have a boolean True
2471 value again.
2472
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002473- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2474 by denying s# to parse objects that have a releasebuffer procedure,
2475 and introducing s*.
2476
Georg Brandl1e13ea92008-08-11 09:07:59 +00002477- Issue #3537: Fix an assertion failure when an empty but presized dict
2478 object was stored in the freelist.
2479
Mark Dickinsonb6467572008-08-04 21:30:09 +00002480- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2481 ValueError consistently across platforms.
2482
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002483- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2484 (64bit Unix, for example), unichr() would truncate its argument and return
2485 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2486
Neal Norwitze7d8be82008-07-31 17:17:14 +00002487- Apply security patches from Apple.
2488
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002489- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2490 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2491
Antoine Pitrou92f82162008-07-25 22:22:08 +00002492- Issue #1819: function calls with several named parameters are now on
2493 average 35% faster (as measured by pybench).
2494
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002495- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2496 the python debugger steps into a class statement: the free variables (local
2497 variables defined in an outer scope) would be deleted from the outer scope.
2498
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002499- Issue #2620: Overflow checking when allocating or reallocating memory
2500 was not always being done properly in some python types and extension
2501 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2502 all been updated to perform better checks and places in the code that
2503 would previously leak memory on the error path when such an allocation
2504 failed have been fixed.
2505

2507-------
2508
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002509- Issue #3612: Added some missing basic types in ctypes.wintypes.
2510
Benjamin Petersone977ad42008-08-20 01:42:01 +00002511- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2512 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2513
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002514- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2515 version reported by these tools does not necessarily follow the python
2516 version numbering scheme, so the module is less strict when parsing it.
2517
Nick Coghlanf70385a2008-08-18 12:42:46 +00002518- Issue #2235: Added Py3k warnings for types which will become unhashable
2519 under the stricter __hash__ inheritance rules in 3.0. Several types
2520 which did not meet the rules for hash invariants and were already
2521 unhashable in 3.0 have now been explicitly flagged as unhashable in
2522 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2523 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2524
Brett Cannon88f801d2008-08-18 00:46:22 +00002525- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2526 imported into the module but exposed as part of the module's API.
2527
Brett Cannon7b96f072008-08-18 00:41:11 +00002528- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2529

2533
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002534- Issue #3575: Incremental decoder's decode function now takes bytearray
2535 by using 's*' instead of 't#'.
2536
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002537- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002538 fails unicode conversion on 2nd parameter. (windows only)
2539
Facundo Batista94f243a2008-08-17 03:38:39 +00002540- Issue 2464. urllib2 now supports a malformation in the URL received
2541 in a redirect.
2542
Brett Cannonabe423e2008-08-16 21:47:07 +00002543- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002544 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002545
Facundo Batistaeb90b782008-08-16 14:44:07 +00002546- Issue #2776: fixed small issue when handling an URL with double slash
2547 after a 302 response in the case of not going through a proxy.
2548
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002549- Issue #2676: in the email package, content-type parsing was hanging on
2550 pathological input because of quadratic or exponential behaviour of a
2551 regular expression.
2552
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002553- Issue #3476: binary buffered reading through the new "io" library is now
2554 thread-safe.
2555
Brett Cannonbf3157b2008-08-14 05:00:03 +00002556- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2557 since mimetools itself is deprecated. Because modules are cached, all
2558 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2559
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002560- Issue #3134: shutil referenced undefined WindowsError symbol.
2561
Robert Schuppenies14646332008-08-10 11:01:53 +00002562- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2563 menu entries were not deleted.

Benjamin Peterson01a24322008-07-28 23:35:27 +00002593- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002594 asking for a specific length. This problem only affected files opened
2595 using the new "io" module, not the built-in open() function.

2623
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002624- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2637 interaction with the tp_hash slot (added in 2.6b2) are now documented
2638
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002639- Issue #643841: The language reference now provides more detailed

2651-----------------
2652
Georg Brandl3e483f62008-07-16 22:57:41 +00002653- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2654 its methods now allow for items objects that can be converted to
2655 an integer using operator.index().
2656
Mark Dickinson64b7e502008-07-16 09:40:03 +00002657- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2658 produced a ValueError instead of giving the correct float.
2659
Eric Smitha5fa5a22008-07-16 00:11:49 +00002660- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2661 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2662
Mark Dickinson7103aa42008-07-15 19:08:33 +00002663- Issue #3008: the float type has a new instance method 'float.hex'
2664 and a new class method 'float.fromhex' to convert floating-point
2665 numbers to and from hexadecimal strings, respectively.
2666
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002667- Issue #2235: __hash__ is once again inherited by default. To allow
2668 collections.Hashable to remain meaningful in the presence of the
2669 default hash implementation (object.__hash__), it is now possible
2670 to explicit block inheritance of hash by setting __hash__=None at
2671 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2672 level.
2673
Nick Coghlanb028f502008-07-13 14:52:36 +00002674- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2675 the parent module cannot be found while performing an absolute import.
2676 This means that an incorrectly defined __package__ attribute will
2677 now only prevent relative imports in that module rather than causing
2678 all imports from that module to fail.
2679
Nick Coghlan14ff9942008-07-08 14:21:42 +00002680- Issue #2517: Allow unicode messages in Exceptions again by correctly

2690 another thread's dictionary.
2691
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002692- Issue #3004: Minor change to slice.indices(): the start and stop
2693 arguments are now treated identically, making the behaviour easier
2694 to describe and understand. For example, slice(None, -10,
2695 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2696 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2697 10, -1).
2698
Georg Brandl278fc502008-07-19 12:46:12 +00002699- Issue #3219: Calling a function with repeated keyword arguments,
2700 f(a=2, a=23), would not cause a syntax error. This was a regression
2701 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002703- Issue #2862: Make int and float freelist management consistent with
2704 other freelists. Changes their CompactFreeList apis into

2712 error when they failed.
2713
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002714- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002739- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2740 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002741 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002742 content-length. The problem had been corrected in the 2.4 branch, but never
2743 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002758- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3146
Brett Cannonb61d8012008-05-11 23:39:04 +00003147- ``Lib/lib-old`` is now added to sys.path.
3148
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003149- On MacOS X it is now possible to install the framework in 64-bit
3150 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003151 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003152
3153 This is controlled by the configure argument ``--with-universal-archs``:
3154
3155 - ``--with-universal-archs=all``: install 4-way universal
3156
3157 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3158
3159 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3160
3161 This option should be used in combination with ``--enable-universalsdk=``.
3162
3163 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 +00003172
3173- The PyString functions have been renamed to PyBytes. A batch of
3174 defines were added so that the linker still sees the original
3175 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003213- Issue #1631171: Re-implement the 'warnings' module in C (the
3214 original Python code has been kept as backup). This will allow for
3215 using the 'warning's machinery in such places as the parser where
3216 use of pure Python code is not possible. Both the ``showarning()``
3217 and ``formatwarning()`` gain an optional 'line' argument which is
3218 not called by default for backwards-compatibility reasons. Setting
3219 ``warnings.showwarning()`` to an implementation that lacks support
3220 for the ``line`` argument will raise a DeprecationWarning.

3244
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003245- The getpass module has been improved on Unix. It now uses /dev/tty
3246 by default and uses stderr instead of stdout. A GetPassWarning is
3247 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00003248

3260 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00003261
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003263 extension modules between 32 and 64 bit platforms. See the distutls

3276 so the controlled environment will more closely mirror the typical
3277 script environment. This supports setup.py scripts that refer to
3278 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003283- Issue #2550: The approach used by client/server code for obtaining
3284 ports to listen on in network-oriented tests has been refined in an
3285 effort to facilitate running multiple instances of the entire
3286 regression test suite in parallel without issue.
3287 test_support.bind_port() has been fixed such that it will always
3288 return a unique port -- which wasn't always the case with the
3289 previous implementation, especially if socket options had been set
3290 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3291 new implementation of bind_port() will actually raise an exception
3292 if it is passed an AF_INET/SOCK_STREAM socket with either the
3293 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3294 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3295 the socket it's been passed. This currently only applies to
3296 Windows. This option prevents any other sockets from binding to the
3297 host/port we've bound to, thus removing the possibility of the
3298 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3299 when a second SOCK_STREAM socket binds and accepts to a host/port
3300 that's already been bound by another socket. The optional preferred
3301 port parameter to bind_port() has been removed. Under no
3302 circumstances should tests be hard coding ports!
3303
3304 test_support.find_unused_port() has also been introduced, which will
3305 pass a temporary socket object to bind_port() in order to obtain an
3306 unused port. The temporary socket object is then closed and
3307 deleted, and the port is returned. This method should only be used
3308 for obtaining an unused port in order to pass to an external program
3309 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3310 a parameter to a server-oriented class that doesn't give you direct
3311 access to the underlying socket used.
3312
3313 Finally, test_support.HOST has been introduced, which should be used
3314 for the host argument of any relevant socket calls (i.e. bind and
3315 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003316
3317 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003318 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003319 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3320 test_asynchat and test_socket_ssl.
3321
Georg Brandl3ee81df2008-05-17 18:14:43 +00003322 It is now possible for multiple instances of the regression test
3323 suite to run in parallel without issue.

3590-----------------
3591
Fred Drakea8ee94b2008-03-01 02:45:07 +00003592- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003593 644. The mode is now inherited from the py file.

3596
3597- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003598
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003599- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003600 issue 215555 for a discussion.
3601
Eric Smitha73fbe72008-02-23 03:09:44 +00003602- Added the future_builtins module, which contains hex() and oct().
3603 These are the PEP 3127 version of these functions, designed to be
3604 compatible with the hex() and oct() builtins from Python 3.0. They
3605 differ slightly in their output formats from the existing, unchanged
3606 Python 2.6 builtins. The expected usage of the future_builtins
3607 module is:
3608 from future_builtins import hex, oct
3609
Eric Smith7ef40bf2008-02-20 23:34:22 +00003610- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3611 exponents for exponents with absolute value < 100. Follows C99
3612 standard. This is a change on Windows, which would use 3 digits.
3613 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3614 so that any alterations it does to the resulting string will be
3615 available in stringlib/formatter.h (for float.__format__).
3616
Eric Smith5a3c1352008-02-19 13:21:56 +00003617- Implemented PEP 3101, Advanced String Formatting. This adds a new
3618 builtin format(); a format() method for str and unicode; a
3619 __format__() method to object, str, unicode, int, long, float, and
3620 datetime; the class string.Formatter; and the C API
3621 PyObject_Format().
3622
Georg Brandl3ee81df2008-05-17 18:14:43 +00003623- Fixed several potential crashes, all caused by specially crafted
3624 __del__ methods exploiting objects in temporarily inconsistent
3625 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003626
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003627- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003628 prevent a possible crash: an Abstract Base Class would try to access
3629 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003630

Georg Brandl3ee81df2008-05-17 18:14:43 +00003634- Clear all free lists during a gc.collect() of the highest generation
3635 in order to allow pymalloc to free more arenas. Python may give back
3636 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003637
Georg Brandl3ee81df2008-05-17 18:14:43 +00003638- Issue #2045: Fix an infinite recursion triggered when printing a
3639 subclass of collections.defaultdict, if its default_factory is set
3640 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003641
Christian Heimesf75dbef2008-02-08 00:11:31 +00003642- Fixed a minor memory leak in dictobject.c. The content of the free
3643 list was not freed on interpreter shutdown.
3644
Georg Brandl3ee81df2008-05-17 18:14:43 +00003645- Limit free list of method and builtin function objects to 256
3646 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003647
Georg Brandl3ee81df2008-05-17 18:14:43 +00003648- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3649 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003650 to compact the internal free lists of pre-allocted ints and floats.
3651
Georg Brandl3ee81df2008-05-17 18:14:43 +00003652- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3653 calls. Python expected the return type int but the fork familie
3654 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003655
Georg Brandl3ee81df2008-05-17 18:14:43 +00003656- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3657 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003658
Georg Brandl3ee81df2008-05-17 18:14:43 +00003659- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3660 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003661
Georg Brandl3ee81df2008-05-17 18:14:43 +00003662- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3663 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003664
Georg Brandl3ee81df2008-05-17 18:14:43 +00003665- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3666 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003667
Georg Brandl3ee81df2008-05-17 18:14:43 +00003668- Patch #1473257: generator objects gain a gi_code attribute. This is
3669 the same object as the func_code attribute of the function that
3670 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003671
Georg Brandl3ee81df2008-05-17 18:14:43 +00003672- Issue #1920: "while 0" statements were completely removed by the
3673 compiler, even in the presence of an "else" clause, which is
3674 supposed to be run when the condition is false. Now the compiler
3675 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003676
Guido van Rossumeead05f2008-01-24 18:21:02 +00003677- A few crashers fixed: weakref_in_del.py (issue #1377858);
3678 loosing_dict_ref.py (issue #1303614, test67.py);
3679 borrowed_ref_[34].py (not in tracker).
3680
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003681- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003682 suppressed while an extension is loaded by calling SetErrorMode in
3683 dynload_win.c. The error is still reported properly.
3684
Georg Brandl3ee81df2008-05-17 18:14:43 +00003685- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003686 several extension methods and modules do not work without unicode
3687 support.
3688
Georg Brandl26543b12008-01-21 18:36:51 +00003689- Issue #1882: when compiling code from a string, encoding cookies in the
3690 second line of code were not always recognized correctly.
3691
Georg Brandl14404b62008-01-19 19:27:05 +00003692- Issue #1679: "0x" was taken as a valid integer literal.
3693
Georg Brandl6caad7d2008-01-26 14:19:22 +00003694- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003695 added.
3696
Christian Heimesc94e2b52008-01-14 04:13:37 +00003697- sys.float_info / PyFloat_GetInfo: The floating point information
3698 object was converted from a dict to a specialized structseq object.
3699
Georg Brandl3ee81df2008-05-17 18:14:43 +00003700- Patch #1816: Added sys.flags structseq. It exposes the status of
3701 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003702
Georg Brandl3ee81df2008-05-17 18:14:43 +00003703- Objects/structseq.c: Implemented new structseq representation. The
3704 patch makes structseqs (e.g. the return value of os.stat) more
3705 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003706
Georg Brandl3ee81df2008-05-17 18:14:43 +00003707- Patch #1700288: added a type attribute cache that caches method
3708 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003709
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003710- Bug #1776: __import__() no longer accepts filenames on any platform.
3711 The first parameter to __import__() must be a valid module name.

3716 envvar and sys.dont_write_bytecode attribute. All these can be set
3717 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003718
Georg Brandl3ee81df2008-05-17 18:14:43 +00003719- Improve some exception messages when Windows fails to load an
3720 extension module. Now we get for example '%1 is not a valid Win32
3721 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003722

Christian Heimes0a8143f2007-12-18 23:22:54 +00003728- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729 and INF. float("nan"), float("inf") and float("-inf") now work on
3730 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003731
Georg Brandl3ee81df2008-05-17 18:14:43 +00003732- Compiler now generates simpler and faster code for dictionary
3733 literals. The oparg for BUILD_MAP now indicates an estimated
3734 dictionary size. There is a new opcode, STORE_MAP, for adding
3735 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003764- Patch #1739468: Directories and zipfiles containing a __main__.py
3765 file can now be directly executed by passing their name to the
3766 interpreter. The directory/zipfile is automatically inserted as the
3767 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003769- Issue #1265: Fix a problem with sys.settrace, if the tracing
3770 function uses a generator expression when at the same time the
3771 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003772
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003773- sets and frozensets now have an isdisjoint() method.
3774

3776
Neal Norwitz44f326e2007-10-05 05:29:17 +00003777- Fix warnings found by the new version of the Coverity checker.
3778
Georg Brandl3ee81df2008-05-17 18:14:43 +00003779- The enumerate() builtin function is no longer bounded to sequences
3780 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3781 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003782
Georg Brandl3ee81df2008-05-17 18:14:43 +00003783- Issue #1686386: Tuple's tp_repr did not take into account the
3784 possibility of having a self-referential tuple, which is possible
3785 from C code. Nor did object's tp_str consider that a type's tp_str
3786 could do something that could lead to an inifinite recursion.
3787 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3788 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003789
Georg Brandl3ee81df2008-05-17 18:14:43 +00003790- Issue #1164: It was possible to trigger deadlock when using the
3791 'print' statement to write to a file since the GIL was not released
3792 as needed. Now PyObject_Print() does the right thing along with
3793 various tp_print implementations of the built-in types and those in
3794 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003795
Georg Brandl3ee81df2008-05-17 18:14:43 +00003796- Issue #1147: Exceptions were directly allowing string exceptions in
3797 their throw() method even though string exceptions no longer
3798 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003799
Georg Brandl3ee81df2008-05-17 18:14:43 +00003800- Issue #1096: Prevent a segfault from getting the repr of a very
3801 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003802
Brett Cannon1e534b52007-09-07 04:18:30 +00003803- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003804 PyObject_Call() never calling back out to Python code to trigger
3805 recursion depth updates/checks. Required the creation of a static
3806 RuntimeError instance in case normalizing an exception put the
3807 recursion check value past its limit. Fixes crashers
3808 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003809

Neal Norwitz0ac60192007-05-27 04:08:54 +00003823- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003824 __*__ attributes. (Some already existed, e.g., __doc__ and
3825 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003826
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003827- Add -3 option to the interpreter to warn about features that are
3828 deprecated and will be changed/removed in Python 3.0.
3829
Georg Brandl2134e752007-05-21 20:34:16 +00003830- Patch #1686487: you can now pass any mapping after '**' in function
3831 calls.
3832
Collin Winter62903052007-05-18 23:11:24 +00003833- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003834 "except E as target:". This is to provide forwards compatibility
3835 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003836
Brett Cannon229cee22007-05-05 01:34:02 +00003837- Deprecate BaseException.message as per PEP 352.
3838
Georg Brandl3ee81df2008-05-17 18:14:43 +00003839- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003840 inherited from a builtin base.
3841
Vinay Sajip8549ce32007-05-06 17:53:37 +00003842- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003843 setting a plain string, ie don't expand to single letter identifiers.
3844
Raymond Hettinger13936692007-04-11 18:40:58 +00003845- Request #1191699: Slices can now be pickled.
3846
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003847- Request #1193128: str.translate() now allows a None argument for
3848 translations that only remove characters without re-mapping the
3849 remaining characters.
3850
Georg Brandl5cb76c12007-03-21 09:00:39 +00003851- Patch #1682205: a TypeError while unpacking an iterable is no longer
3852 masked by a generic one with the message "unpack non-sequence".
3853
Neal Norwitzaa754b72007-03-21 06:39:48 +00003854- Remove unused file Python/fmod.c.
3855
Guido van Rossum143b5642007-03-23 04:58:42 +00003856- Bug #1683368: The object.__init__() and object.__new__() methods are
3857 now stricter in rejecting excess arguments. The only time when
3858 either allows excess arguments is when it is not overridden and the
3859 other one is. For backwards compatibility, when both are
3860 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003861 warning later). Also, type.__init__() insists on the same signature
3862 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003863
Georg Brandl3ee81df2008-05-17 18:14:43 +00003864- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3865 object to complex using its __complex__() method before falling back
3866 to the __float__() method. Therefore, the functions in the cmath
3867 module now can operate on objects that define a __complex__()
3868 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003869
Georg Brandl3ee81df2008-05-17 18:14:43 +00003870- Patch #1623563: allow __class__ assignment for classes with
3871 __slots__. The old and the new class are still required to have the
3872 same slot names.

3878 ``object.__reduce_ex__()`` is called with an object that is faking
3879 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003880
Georg Brandl3ee81df2008-05-17 18:14:43 +00003881- Patch #1680015: Don't modify __slots__ tuple if it contains an

3885
Georg Brandl7b9c5552007-03-12 14:30:05 +00003886- Bug #1678647: write a newline after printing an exception in any
3887 case, even when converting the value to a string failed.
3888
Georg Brandl871f1bc2007-03-12 13:17:36 +00003889- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003890 its argument, if it exists. If not, it will work like before. This
3891 allows customizing the output of dir() in the presence of a
3892 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003894- Patch #922167: Python no longer segfaults when faced with infinitely
3895 self-recursive reload() calls (as reported by bug #742342).
3896

Georg Brandl4e933132006-09-06 20:05:58 +00004007- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004416 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004457 AttributeError instead of an IOError when the server's response

4549 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004942 time so that opening a database previously created with the DB_DUP
4943 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4944 opens. Specifically: dictionary assignment to a DB object will
4945 replace all values for a given key when the database allows
4946 duplicate values. DB users should use DB.put(k, v) when they want
4947 to store duplicates; not DB[k] = v.

4954 characters with ASCII value less than 32. Also, it correctly quotes
4955 dots only if they occur on a single line, as opposed to the previous
4956 behavior of quoting dots if they are the second character of any
4957 line.
