Mark Dickinson36ecd672010-01-29 17:11:39 +000015- Issue #7788: Fix an interpreter crash produced by deleting a list
16 slice with very large step value.
17
Eric Smithee931b72010-01-27 00:28:29 +000018- Issue #7766: Change sys.getwindowsversion() return value to a named
19 tuple and add the additional members returned in an OSVERSIONINFOEX
20 structure. The new members are service_pack_major, service_pack_minor,
21 suite_mask, and product_type.
22
Antoine Pitroue80a6a42010-01-17 12:26:20 +000023- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
24 could crash in many places because of the PyByteArray_AS_STRING() macro
25 returning NULL. The macro now returns a statically allocated empty
26 string instead.
27
Antoine Pitrou64672132010-01-13 07:55:48 +000028- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
29 methods of bytes, bytearray and unicode objects by using a common
30 implementation based on stringlib's fast search. Patch by Florent Xicluna.

33 alpha 2, including: (1) a serious 'wrong output' bug that could
34 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
35 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +000036 strings corresponding to subnormal values, (3) a memory leak for
37 some values large enough to cause overflow, and (4) a number of
38 flaws that could lead to incorrectly rounded results.

54
Antoine Pitrou94c33eb2010-01-27 20:59:50 +000055- Issue #7610: Reworked implementation of the internal
56 :class:`zipfile.ZipExtFile` class used to represent files stored inside
57 an archive. The new implementation is significantly faster and can
58 be wrapped in a :class:`io.BufferedReader` object for more speedups.
59 It also solves an issue where interleaved calls to `read()` and
60 `readline()` give wrong results. Patch by Nir Aides.
61

70 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
71 encoded string for them. This ensure that the upload and register commands
72 send the right values to PyPI without any error.
73
R. David Murrayed44dfa2010-01-16 05:15:17 +000074- Issue #1670765: Prevent email.generator.Generator from re-wrapping

93
Tarek Ziadédc0f4872010-01-11 22:50:29 +000094- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since
95 Extension extra options may change the output without changing the .c
96 file). Initial patch by Collin Winter.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000131
132Core and Builtins
133-----------------
134
Benjamin Petersonecdae192010-01-04 00:43:01 +0000135- The __complex__ method is now looked up on the class of instances to make it
136 consistent with other special methods.
137
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000138- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
139 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
140
Mark Dickinson1b34d252010-01-01 17:27:30 +0000141- Issue #5080: A number of functions and methods previously produced a
142 DeprecationWarning when passed a float argument where an integer was
143 expected. These functions and methods now raise TypeError instead.
144 The majority of the effects of this change are in the extension
145 modules, but some core functions and methods are affected: notably
146 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
147 methods.
148
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000149- Issue #7604: Deleting an unset slotted attribute did not raise an

157
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000158- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
159 used to drop the time part of the result.
160
Mark Dickinson46572832009-12-27 14:55:57 +0000161- Issue #1811: improve accuracy and cross-platform consistency for
162 true division of integers: the result of a/b is now correctly
163 rounded for ints a and b (at least on IEEE 754 platforms), and in
164 particular does not depend on the internal representation of a long.
165
Ezio Melottif84caf42009-12-24 22:25:17 +0000166- Issue #6108: unicode(exception) and str(exception) should return the same
167 message when only __str__ (and not __unicode__) is overridden in the subclass.
168
Ronald Oussoren92919a62009-12-24 13:30:58 +0000169- Issue #6834: replace the implementation for the 'python' and 'pythonw'
170 executables on OSX.
171
172 These executables now work properly with the arch(1) command:
173 ``arch -ppc python`` will start a universal binary version of python
174 in PPC mode (unlike previous releases).
175
R. David Murray0a0a1a82009-12-14 16:28:26 +0000176- Issue #1680159: unicode coercion during an 'in' operation no longer masks
177 the underlying error when the coercion fails for the left hand operand.
178
Benjamin Peterson4895af42009-12-13 16:36:53 +0000179- Issue #7491: Metaclass's __cmp__ method was ignored.
180
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000181- Issue #7466: segmentation fault when the garbage collector is called

195 by Arfrever.
196
Antoine Pitrou80157252010-01-08 19:20:17 +0000197- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
198 renaming of `cPickle` to `pickle`. The warning was annoying since there's
199 no alternative to cPickle if you care about performance. Patch by Florent
200 Xicluna.
201
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000202- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

210 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
211
212- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000213 parameter to allow specifying where your connections come from.

227 the Distutils upload command to avoid an error when PyPI reads it.
228 This occurs on long passwords. Initial patch by JP St. Pierre.
229
230- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000231 Patch by Tatsuhiro Tsujikawa.
232
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000233- Issue #7349: Make methods of file objects in the io module accept None as an
234 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
235 the same as passing no argument.
236
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000237- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

Mark Dickinsonb678de82009-11-19 18:41:49 +0000332- Issue #7117: repr(x) for a float x returns a result based on the
333 shortest decimal string that's guaranteed to round back to x under
334 correct rounding (with round-half-to-even rounding mode).
335 Previously it gave a string based on rounding x to 17 decimal digits.
336 repr(x) for a complex number behaves similarly. On platforms where
337 the correctly-rounded strtod and dtoa code is not supported (see below),
338 repr is unchanged.
339
340- Issue #7117: On almost all platforms: float-to-string and
341 string-to-float conversions within Python are now correctly rounded.
342 Places these conversions occur include: str for floats and complex
343 numbers; the float and complex constructors; old-style and new-style
344 numeric formatting; serialization and deserialization of floats and
345 complex numbers using marshal, pickle and json; parsing of float and
346 imaginary literals in Python code; Decimal-to-float conversion.
347
348 The conversions use a Python-adapted version of David Gay's
349 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
350 functions. This code is supported on Windows, and on Unix-like
351 platforms using gcc, icc or suncc as the C compiler. There may be a
352 small number of platforms on which correct operation of this code
353 cannot be guaranteed, so the code is not used: notably, this applies
354 to platforms where the C double format is not IEEE 754 binary64, and
355 to platforms on x86 hardware where the x87 FPU is set to 64-bit
356 precision and Python's configure script is unable to determine how
357 to change the FPU precision. On these platforms conversions use the
358 platform strtod and dtoa, as before.
359
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000360- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000361 now uses the correctly-rounded string <-> float conversions
362 described above (when available), and so produces correctly rounded
363 results that will display nicely under the float repr. There are
364 two related small changes: (1) round now accepts any class with an
365 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000366 floats for the second argument), and (2) an excessively large second
367 integer argument (e.g., round(1.234, 10**100)) no longer raises an
368 exception.

Eric Smitha985a3a2009-05-05 18:26:08 +0000516- Issue #5920: For float.__format__, change the behavior with the

518 to be like 'g' but with at least one decimal point and with a
519 default precision of 12. Previously, the behavior the same but with
520 a default precision of 6. This more closely matches str(), and
521 reduces surprises when adding alignment flags to the empty

618 float arguments.
619
Raymond Hettinger08259e82009-02-18 23:10:19 +0000620- Running Python with the -3 option now also warns about classic division
621 for ints and longs.
622
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000623- Issue #5260: Long integers now consume less memory: average

632
Benjamin Petersone18ef192009-01-20 14:21:16 +0000633- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
634
Georg Brandl29c6a282009-04-05 20:23:13 +0000635- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000636 were suppressing all exceptions. These include list(), filter(), map(),
637 zip(), and bytearray().
638
Benjamin Peterson596d3062009-01-19 15:42:23 +0000639- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
640 functions.
641
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000642- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

646
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000647- Issue #4935: The overflow checking code in the expandtabs() method common
648 to str, bytes and bytearray could be optimized away by the compiler, letting
649 the interpreter segfault instead of raising an error.
650
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000651- Issue #3720: Fix a crash when an iterator modifies its class and removes its

657
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000658- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
659 collecting the oldest generation) so that allocating lots of objects without
660 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000661 Martin von Löwis at

665
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000666- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
667 an existing .py counterpart, override the co_filename attributes of all
668 code objects if the original filename is obsolete (which can happen if the
669 file has been renamed, moved, or if it is accessed through different paths).
670 Patch by Ziga Seilnacht and Jean-Paul Calderone.
671
Martin v. Löwis5344c992009-01-02 20:32:55 +0000672- Issue #4075: Use OutputDebugStringW in Py_FatalError.

676
Antoine Pitrouaa687902009-01-01 14:11:22 +0000677- Issue #3680: Reference cycles created through a dict, set or deque iterator
678 did not get collected.
679
Nick Coghlan180e4002008-12-30 01:18:48 +0000680- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
681 where the tp_hash and tp_dict slots are both NULL.
682
Benjamin Peterson7af65562008-12-29 17:56:58 +0000683- Issue #4764: With io.open, IOError.filename is set when trying to open a

690 bytearray.translate(). It was always allowed for bytes.translate().
691
Skip Montanarof205c132008-12-23 03:30:15 +0000692- Added test case to ensure attempts to read from a file opened for writing
693 fail.
694
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000695- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

705 context manager returns a value that cannot be converted to a bool.
706
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000707- Issue #4597: Fixed several opcodes that weren't always propagating
708 exceptions.
709
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000710- Issue #4445: Replace "sizeof(PyStringObject)" with
711 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
712 str instances. On a typical machine this saves 3 bytes of memory
713 (on average) per string allocation.
714
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000715- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
716 interpreter to abort ("Fatal Python error: Could not reset the stack!")
717 instead of throwing a MemoryError.
718
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000719- Issue #3689: The list reversed iterator now supports __length_hint__
720 instead of __len__. Behavior now matches other reversed iterators.
721
Benjamin Petersonc078f922008-11-21 22:27:24 +0000722- Issue #4367: Python would segfault during compiling when the unicodedata
723 module couldn't be imported and \N escapes were present.
724
Vinay Sajip213faca2008-12-03 23:22:58 +0000725- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000726 method on file objects with closefd=False. The file descriptor is still
727 kept open but the file object behaves like a closed file. The ``FileIO``
728 object also got a new readonly attribute ``closefd``.
729
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000730- Issue #4348: Some bytearray methods returned that didn't cause any change to
731 the bytearray, returned the same bytearray instead of a copy.
732
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000733- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
734

736
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000737- Issue #4048: The parser module now correctly validates relative imports.
738
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000739- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
740 exec statement.
741
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000742- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
743 method does not return iterators for the 4th and 5th items.
744
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000745- Issue #4209: Enabling unicode_literals and the print_function in the same
746 __future__ import didn't work.
747
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000748- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000749 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000750
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000751- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
752 returned a path longer than MAX_PATH. (But It's doubtful this code path is
753 really executed because I cannot move to such directory on win2k)
754
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000755- Issue #4069: When set.remove(element) is used with a set element, the element
756 is temporarily replaced with an equivalent frozenset. But the eventual
757 KeyError would always report the empty frozenset([]) as the missing key. Now
758 it correctly refers to the initial element.
759
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000760- Issue #4509: Various issues surrounding resize of bytearray objects to
761 which there are buffer exports.

771
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000772- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
773 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000775- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
776 returned them on 64bit platforms.
777
Walter Dörwalded960ac2009-05-03 22:36:33 +0000778- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
779 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
780 step. This avoids problems with counting UTF-8 bytes that ignores the effect
781 of using the replace error handler in PyUnicode_DecodeUTF8().
782
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000783- Issue #3739: The unicode-internal encoder now reports the number of characters
784 consumed like any other encoder (instead of the number of bytes).
785
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000786- Issue #2422: When compiled with the ``--with-valgrind`` option, the
787 pymalloc allocator will be automatically disabled when running under
788 Valgrind. This gives improved memory leak detection when running
789 under Valgrind, while taking advantage of pymalloc at other times.

2170
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002171- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2172 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2173 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2174 ``printf`` function, whereas PyString_FromFormat has an independent
2175 implementation and uses "%zd" on all platforms for size_t values.
2176 This makes a difference on win64, where ``printf`` needs "%Id" to display
2177 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002179- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2183 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002194 was correctly parsed but parsing of subsequent arguments failed.
2195
Vinay Sajip35e3b032008-09-01 14:33:59 +00002196- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002197 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2198 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2199 when given a tuple of classes as second argument, were looking up
2200 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2201 type object.

2298
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002299- Issue #2975: When compiling several extension modules with Visual Studio 2008

2301 without limit.
2302
Benjamin Peterson37346b22008-08-23 20:27:43 +00002303- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002340What's New in Python 2.6 beta 3?
2341================================
2342
Barry Warsaw07a4a382008-08-21 01:15:08 +00002343*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002344
2345Core and Builtins
2346-----------------
2347
Guido van Rossumf8402962008-08-20 15:01:50 +00002348- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2349 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2350 extensions do not automatically benefit from the class attribute
2351 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2352 to their tp_flags field if they care. This is a backwards
2353 compatibility feature; in 3.0, all types will use the cache by
2354 default.
2355
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002356- Keyword arguments can now follow starred arguments. (``f(a, *args,
2357 keyword=23)`` is now valid syntax.)
2358
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002359- ctypes function pointers that are COM methods have a boolean True
2360 value again.
2361
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002362- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2363 by denying s# to parse objects that have a releasebuffer procedure,
2364 and introducing s*.
2365
Georg Brandl1e13ea92008-08-11 09:07:59 +00002366- Issue #3537: Fix an assertion failure when an empty but presized dict
2367 object was stored in the freelist.
2368
Mark Dickinsonb6467572008-08-04 21:30:09 +00002369- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2370 ValueError consistently across platforms.
2371
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002372- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2373 (64bit Unix, for example), unichr() would truncate its argument and return
2374 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2375
Neal Norwitze7d8be82008-07-31 17:17:14 +00002376- Apply security patches from Apple.
2377
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002378- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2379 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2380
Antoine Pitrou92f82162008-07-25 22:22:08 +00002381- Issue #1819: function calls with several named parameters are now on
2382 average 35% faster (as measured by pybench).
2383
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002384- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2385 the python debugger steps into a class statement: the free variables (local
2386 variables defined in an outer scope) would be deleted from the outer scope.
2387
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002388- Issue #2620: Overflow checking when allocating or reallocating memory
2389 was not always being done properly in some python types and extension
2390 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2391 all been updated to perform better checks and places in the code that
2392 would previously leak memory on the error path when such an allocation
2393 failed have been fixed.
2394
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002395Library
2396-------
2397
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002398- Issue #3612: Added some missing basic types in ctypes.wintypes.
2399
Benjamin Petersone977ad42008-08-20 01:42:01 +00002400- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2401 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2402
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002403- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2404 version reported by these tools does not necessarily follow the python
2405 version numbering scheme, so the module is less strict when parsing it.
2406
Nick Coghlanf70385a2008-08-18 12:42:46 +00002407- Issue #2235: Added Py3k warnings for types which will become unhashable
2408 under the stricter __hash__ inheritance rules in 3.0. Several types
2409 which did not meet the rules for hash invariants and were already
2410 unhashable in 3.0 have now been explicitly flagged as unhashable in
2411 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2412 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2413
Brett Cannon88f801d2008-08-18 00:46:22 +00002414- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2415 imported into the module but exposed as part of the module's API.
2416

2418
Brett Cannon46225e72008-08-18 00:36:52 +00002419- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002421- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2422
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002423- Issue #3575: Incremental decoder's decode function now takes bytearray
2424 by using 's*' instead of 't#'.
2425
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002426- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002427 fails unicode conversion on 2nd parameter. (windows only)
2428
Facundo Batista94f243a2008-08-17 03:38:39 +00002429- Issue 2464. urllib2 now supports a malformation in the URL received
2430 in a redirect.
2431
Brett Cannonabe423e2008-08-16 21:47:07 +00002432- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002433 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002434
Facundo Batistaeb90b782008-08-16 14:44:07 +00002435- Issue #2776: fixed small issue when handling an URL with double slash
2436 after a 302 response in the case of not going through a proxy.
2437
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002438- Issue #2676: in the email package, content-type parsing was hanging on
2439 pathological input because of quadratic or exponential behaviour of a
2440 regular expression.
2441
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002442- Issue #3476: binary buffered reading through the new "io" library is now
2443 thread-safe.
2444
Brett Cannonbf3157b2008-08-14 05:00:03 +00002445- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2446 since mimetools itself is deprecated. Because modules are cached, all
2447 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2448
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002449- Issue #3134: shutil referenced undefined WindowsError symbol.
2450
Robert Schuppenies14646332008-08-10 11:01:53 +00002451- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2452 menu entries were not deleted.
2453
Brett Cannon83e81842008-08-09 23:30:55 +00002454- Copied the implementation of reduce() to _functools.reduce() to have a
2455 version that did not raise a DeprecationWarning under -3.
2456
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002457- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2458 a MemoryError rather than silently stop the iteration.
2459
Guido van Rossum59ce9012008-08-09 14:55:34 +00002460- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2461 to _sre.compile() will now be rejected. This should not affect anybody
2462 since the re.compile() function never generates invalid re-bytecode.
2463
Skip Montanaroa032bf42008-08-08 22:52:51 +00002464- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2465 upon first access it can be automatically initialized from the csv file if
2466 it wasn't initialized during instantiation.
2467
Brett Cannon3aa2a492008-08-06 22:28:09 +00002468- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2469 the reload() built-in has been removed.
2470
Brett Cannon7e30b672008-08-04 21:52:25 +00002471- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002472 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2480 raised an AttributeError.
2481
Benjamin Peterson01a24322008-07-28 23:35:27 +00002482- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002483 asking for a specific length. This problem only affected files opened
2484 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002485

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002509- Issue #3394: zipfile.writestr sets external attributes when passed a
2510 file name rather than a ZipInfo instance, so files are extracted with
2511 mode 0600 rather than 000 under Unix.
2512
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002513- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2514 argument in python 2.5, this broke code that subclassed Popen to include its

2529 coverage of the lookup process for special methods. The disclaimers
2530 regarding lack of coverage of new-style classes have also been
2531 removed, since the coverage is now fairly reasonable.

2540-----------------
2541
Georg Brandl3e483f62008-07-16 22:57:41 +00002542- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2543 its methods now allow for items objects that can be converted to
2544 an integer using operator.index().
2545
Mark Dickinson64b7e502008-07-16 09:40:03 +00002546- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2547 produced a ValueError instead of giving the correct float.
2548
Eric Smitha5fa5a22008-07-16 00:11:49 +00002549- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2550 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2551
Mark Dickinson7103aa42008-07-15 19:08:33 +00002552- Issue #3008: the float type has a new instance method 'float.hex'
2553 and a new class method 'float.fromhex' to convert floating-point
2554 numbers to and from hexadecimal strings, respectively.
2555
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002556- Issue #2235: __hash__ is once again inherited by default. To allow
2557 collections.Hashable to remain meaningful in the presence of the
2558 default hash implementation (object.__hash__), it is now possible
2559 to explicit block inheritance of hash by setting __hash__=None at
2560 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2561 level.
2562
Nick Coghlanb028f502008-07-13 14:52:36 +00002563- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2564 the parent module cannot be found while performing an absolute import.
2565 This means that an incorrectly defined __package__ attribute will
2566 now only prevent relative imports in that module rather than causing
2567 all imports from that module to fail.
2568

Georg Brandl5cc774e2008-06-11 20:28:06 +00003040 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003041
3042 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00003102- Issue #1631171: Re-implement the 'warnings' module in C (the
3103 original Python code has been kept as backup). This will allow for
3104 using the 'warning's machinery in such places as the parser where
3105 use of pure Python code is not possible. Both the ``showarning()``
3106 and ``formatwarning()`` gain an optional 'line' argument which is
3107 not called by default for backwards-compatibility reasons. Setting
3108 ``warnings.showwarning()`` to an implementation that lacks support
3109 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003172- Issue #2550: The approach used by client/server code for obtaining
3173 ports to listen on in network-oriented tests has been refined in an
3174 effort to facilitate running multiple instances of the entire
3175 regression test suite in parallel without issue.
3176 test_support.bind_port() has been fixed such that it will always
3177 return a unique port -- which wasn't always the case with the
3178 previous implementation, especially if socket options had been set
3179 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3180 new implementation of bind_port() will actually raise an exception
3181 if it is passed an AF_INET/SOCK_STREAM socket with either the
3182 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3183 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3184 the socket it's been passed. This currently only applies to
3185 Windows. This option prevents any other sockets from binding to the
3186 host/port we've bound to, thus removing the possibility of the
3187 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3188 when a second SOCK_STREAM socket binds and accepts to a host/port
3189 that's already been bound by another socket. The optional preferred
3190 port parameter to bind_port() has been removed. Under no
3191 circumstances should tests be hard coding ports!
3192
3193 test_support.find_unused_port() has also been introduced, which will
3194 pass a temporary socket object to bind_port() in order to obtain an
3195 unused port. The temporary socket object is then closed and
3196 deleted, and the port is returned. This method should only be used
3197 for obtaining an unused port in order to pass to an external program
3198 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3199 a parameter to a server-oriented class that doesn't give you direct
3200 access to the underlying socket used.
3201
3202 Finally, test_support.HOST has been introduced, which should be used
3203 for the host argument of any relevant socket calls (i.e. bind and
3204 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003205
3206 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003207 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003208 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3209 test_asynchat and test_socket_ssl.
3210
Georg Brandl3ee81df2008-05-17 18:14:43 +00003211 It is now possible for multiple instances of the regression test
3212 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00003481- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003482 644. The mode is now inherited from the py file.

3485
3486- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003487
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003488- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003489 issue 215555 for a discussion.
3490
Eric Smitha73fbe72008-02-23 03:09:44 +00003491- Added the future_builtins module, which contains hex() and oct().
3492 These are the PEP 3127 version of these functions, designed to be
3493 compatible with the hex() and oct() builtins from Python 3.0. They
3494 differ slightly in their output formats from the existing, unchanged
3495 Python 2.6 builtins. The expected usage of the future_builtins
3496 module is:
3497 from future_builtins import hex, oct
3498
Eric Smith7ef40bf2008-02-20 23:34:22 +00003499- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3500 exponents for exponents with absolute value < 100. Follows C99
3501 standard. This is a change on Windows, which would use 3 digits.
3502 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3503 so that any alterations it does to the resulting string will be
3504 available in stringlib/formatter.h (for float.__format__).
3505
Eric Smith5a3c1352008-02-19 13:21:56 +00003506- Implemented PEP 3101, Advanced String Formatting. This adds a new
3507 builtin format(); a format() method for str and unicode; a
3508 __format__() method to object, str, unicode, int, long, float, and
3509 datetime; the class string.Formatter; and the C API
3510 PyObject_Format().
3511
Georg Brandl3ee81df2008-05-17 18:14:43 +00003512- Fixed several potential crashes, all caused by specially crafted
3513 __del__ methods exploiting objects in temporarily inconsistent
3514 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003515
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003516- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003517 prevent a possible crash: an Abstract Base Class would try to access
3518 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003519

Georg Brandl3ee81df2008-05-17 18:14:43 +00003523- Clear all free lists during a gc.collect() of the highest generation
3524 in order to allow pymalloc to free more arenas. Python may give back
3525 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003526
Georg Brandl3ee81df2008-05-17 18:14:43 +00003527- Issue #2045: Fix an infinite recursion triggered when printing a
3528 subclass of collections.defaultdict, if its default_factory is set
3529 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003530
Christian Heimesf75dbef2008-02-08 00:11:31 +00003531- Fixed a minor memory leak in dictobject.c. The content of the free
3532 list was not freed on interpreter shutdown.
3533
Georg Brandl3ee81df2008-05-17 18:14:43 +00003534- Limit free list of method and builtin function objects to 256
3535 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003536
Georg Brandl3ee81df2008-05-17 18:14:43 +00003537- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3538 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003539 to compact the internal free lists of pre-allocted ints and floats.
3540
Georg Brandl3ee81df2008-05-17 18:14:43 +00003541- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3542 calls. Python expected the return type int but the fork familie
3543 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003544
Georg Brandl3ee81df2008-05-17 18:14:43 +00003545- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3546 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003547
Georg Brandl3ee81df2008-05-17 18:14:43 +00003548- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3549 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003554- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3555 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003556
Georg Brandl3ee81df2008-05-17 18:14:43 +00003557- Patch #1473257: generator objects gain a gi_code attribute. This is
3558 the same object as the func_code attribute of the function that
3559 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003560
Georg Brandl3ee81df2008-05-17 18:14:43 +00003561- Issue #1920: "while 0" statements were completely removed by the
3562 compiler, even in the presence of an "else" clause, which is
3563 supposed to be run when the condition is false. Now the compiler
3564 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003565
Guido van Rossumeead05f2008-01-24 18:21:02 +00003566- A few crashers fixed: weakref_in_del.py (issue #1377858);
3567 loosing_dict_ref.py (issue #1303614, test67.py);
3568 borrowed_ref_[34].py (not in tracker).
3569
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003570- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003571 suppressed while an extension is loaded by calling SetErrorMode in
3572 dynload_win.c. The error is still reported properly.
3573
Georg Brandl3ee81df2008-05-17 18:14:43 +00003574- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003575 several extension methods and modules do not work without unicode
3576 support.
3577
Georg Brandl26543b12008-01-21 18:36:51 +00003578- Issue #1882: when compiling code from a string, encoding cookies in the
3579 second line of code were not always recognized correctly.
3580
Georg Brandl14404b62008-01-19 19:27:05 +00003581- Issue #1679: "0x" was taken as a valid integer literal.
3582
Georg Brandl6caad7d2008-01-26 14:19:22 +00003583- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003584 added.
3585
Christian Heimesc94e2b52008-01-14 04:13:37 +00003586- sys.float_info / PyFloat_GetInfo: The floating point information
3587 object was converted from a dict to a specialized structseq object.
3588
Georg Brandl3ee81df2008-05-17 18:14:43 +00003589- Patch #1816: Added sys.flags structseq. It exposes the status of
3590 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003591
Georg Brandl3ee81df2008-05-17 18:14:43 +00003592- Objects/structseq.c: Implemented new structseq representation. The
3593 patch makes structseqs (e.g. the return value of os.stat) more
3594 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003595
Georg Brandl3ee81df2008-05-17 18:14:43 +00003596- Patch #1700288: added a type attribute cache that caches method

3605 envvar and sys.dont_write_bytecode attribute. All these can be set
3606 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003607
Georg Brandl3ee81df2008-05-17 18:14:43 +00003608- Improve some exception messages when Windows fails to load an
3609 extension module. Now we get for example '%1 is not a valid Win32
3610 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003611

Christian Heimes0a8143f2007-12-18 23:22:54 +00003617- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003618 and INF. float("nan"), float("inf") and float("-inf") now work on
3619 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003620
Georg Brandl3ee81df2008-05-17 18:14:43 +00003621- Compiler now generates simpler and faster code for dictionary
3622 literals. The oparg for BUILD_MAP now indicates an estimated
3623 dictionary size. There is a new opcode, STORE_MAP, for adding
3624 entries to the dictionary.

3654 file can now be directly executed by passing their name to the
3655 interpreter. The directory/zipfile is automatically inserted as the
3656 first entry in sys.path.

3667
Georg Brandl3ee81df2008-05-17 18:14:43 +00003668- The enumerate() builtin function is no longer bounded to sequences
3669 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3670 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003671
Georg Brandl3ee81df2008-05-17 18:14:43 +00003672- Issue #1686386: Tuple's tp_repr did not take into account the
3673 possibility of having a self-referential tuple, which is possible
3674 from C code. Nor did object's tp_str consider that a type's tp_str
3675 could do something that could lead to an inifinite recursion.
3676 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3677 issues.

3680 'print' statement to write to a file since the GIL was not released
3681 as needed. Now PyObject_Print() does the right thing along with
3682 various tp_print implementations of the built-in types and those in
3683 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003693 PyObject_Call() never calling back out to Python code to trigger
3694 recursion depth updates/checks. Required the creation of a static

3721
Collin Winter62903052007-05-18 23:11:24 +00003722- except clauses may now be spelled either "except E, target:" or

3724 with Python 3.0.

3730
Vinay Sajip8549ce32007-05-06 17:53:37 +00003731- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003732 setting a plain string, ie don't expand to single letter identifiers.
3733
Raymond Hettinger13936692007-04-11 18:40:58 +00003734- Request #1191699: Slices can now be pickled.

3744
Guido van Rossum143b5642007-03-23 04:58:42 +00003745- Bug #1683368: The object.__init__() and object.__new__() methods are
3746 now stricter in rejecting excess arguments. The only time when
3747 either allows excess arguments is when it is not overridden and the
3748 other one is. For backwards compatibility, when both are
3749 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003750 warning later). Also, type.__init__() insists on the same signature
3751 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003753- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3754 object to complex using its __complex__() method before falling back
3755 to the __float__() method. Therefore, the functions in the cmath
3756 module now can operate on objects that define a __complex__()
3757 method.

3774
Georg Brandl7b9c5552007-03-12 14:30:05 +00003775- Bug #1678647: write a newline after printing an exception in any
3776 case, even when converting the value to a string failed.
3777
Georg Brandl871f1bc2007-03-12 13:17:36 +00003778- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003779 its argument, if it exists. If not, it will work like before. This
3780 allows customizing the output of dir() in the presence of a
3781 __getattr__().

3785
Georg Brandl3ee81df2008-05-17 18:14:43 +00003786- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003789- Patch #1491866: change the complex() constructor to allow
3790 parthensized forms. This means complex(repr(x)) now works instead of
3791 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003792
Georg Brandlaa2321b2007-03-07 00:40:28 +00003793- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003794 makes the filenames the warning module prints much more sensible
3795 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003808- Patch #1674228: when assigning a slice (old-style), check for the
3809 sq_ass_slice instead of the sq_slice slot.
3810
Georg Brandl3ee81df2008-05-17 18:14:43 +00003811- When printing an unraisable error, don't print exceptions. before
3812 the name. This duplicates the behavior whening normally printing
3813 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004364- Patch #1530482: add pydoc.render_doc() which returns the

4379
Georg Brandl92a6bae2007-03-13 17:43:32 +00004380- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004381 are set for invalid interpolation sequences that would lead to

4438 TestCase and TestSuite subclasses (not instances) are no longer
4439 accepted in TestSuite.addTest(). This should cause no
4440 incompatibility since it never made sense with ordinary subclasses
4441 -- the failure just occurred later, with a more cumbersome
4442 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004723- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4724 with RFC 3207 and forgets any knowledge obtained from the server not
4725 obtained from the TLS negotiation itself. Patch contributed by Bill
4726 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004727
Georg Brandl3ee81df2008-05-17 18:14:43 +00004728- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004729 that the SMTP.starttls() caller no longer needs to call ehlo()
4730 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004731 does not claim to support starttls. Adds the
4732 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4813 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4814 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004816

Georg Brandl3ee81df2008-05-17 18:14:43 +00004831 time so that opening a database previously created with the DB_DUP
4832 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4833 opens. Specifically: dictionary assignment to a DB object will
4834 replace all values for a given key when the database allows
4835 duplicate values. DB users should use DB.put(k, v) when they want
4836 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004837

4843 characters with ASCII value less than 32. Also, it correctly quotes
4844 dots only if they occur on a single line, as opposed to the previous
4845 behavior of quoting dots if they are the second character of any

5108
Guido van Rossum7c862f82007-12-13 20:50:10 +00005109- Bug #1608: use -fwrapv when GCC supports it. This is important,

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005115- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005116 periodic threadstate and signal checking in tight loops. By
5117 default, this option is turned-off. It should only be enabled in
5118 debugged, performance critical applications.

5169-----
5170
Georg Brandl3ee81df2008-05-17 18:14:43 +00005171- Unified naming convention for free lists and their limits. All free
5172 lists in Object/ are named ``free_list``, the counter ``numfree``

5174 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005175
Georg Brandl3ee81df2008-05-17 18:14:43 +00005176- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5177 to ``PyTuple_SetItem``, it can be used to populate a brand new
5178 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005179

5190
Georg Brandl3ee81df2008-05-17 18:14:43 +00005191- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5192 of w# format code incorrectly truncated the length to an int, even
5193 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5194 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005195
Georg Brandl3ee81df2008-05-17 18:14:43 +00005196- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5216
5217- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5218 outside of pystate.c and should not be necessary.
5219
Georg Brandl3ee81df2008-05-17 18:14:43 +00005220- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5221 absolute imports. In earlier versions they might have used relative
5222 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005223
Georg Brandl3ee81df2008-05-17 18:14:43 +00005224- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5225 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005226
Georg Brandl3ee81df2008-05-17 18:14:43 +00005227- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005252- Removed the macfs module. It had been deprecated since Python 2.5.
5253 This lead to the deprecation of macostools.touched() as it relied
5254 solely on macfs and was a no-op under OS X.
