18 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
19 benefit compared to the dynamic memory allocation fallback. Patch by
20 Charles-François Natali.
21
Benjamin Peterson821a8ea2010-04-16 22:35:38 +000022- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

Antoine Pitroua6240402010-04-25 21:40:32 +000036- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
37 where the method could block indefinitely if called just before the
38 event loop started running. This also fixes the occasional freezes
39 witnessed in test_httpservers.
40
Antoine Pitroufc69af12010-04-24 20:04:58 +000041- Issue #5103: SSL handshake would ignore the socket timeout and block
42 indefinitely if the other end didn't respond.
43
Antoine Pitrou4d3e3722010-04-24 19:57:01 +000044- The do_handshake() method of SSL objects now adjusts the blocking mode of
45 the SSL structure if necessary (as other methods already do).
46
Georg Brandl4341e542010-04-24 09:08:10 +000047- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.

54
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +000055- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of

57 and keywords.
58
Antoine Pitroua5c4b552010-04-22 23:33:02 +000059- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
60 a non-infinite timeout. Also make that method friendlier with applications
61 wanting to continue using the socket in clear-text mode, by disabling
62 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
63
Antoine Pitrouc715a9e2010-04-21 19:28:03 +000064- Issue #8484: Load all ciphers and digest algorithms when initializing
65 the _ssl extension, such that verification of some SSL certificates
66 doesn't fail because of an "unknown algorithm".
67

90 filename and date, conforming to the 'standards' they were originally
91 designed to follow. This improves compatibility with patch tools.
92
R. David Murray27ef9372010-04-12 14:26:06 +000093- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

124Core and Builtins
125-----------------
126
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000127- Issue #7301: Add environment variable $PYTHONWARNINGS.
128
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000129- Issue #8329: Don't return the same lists from select.select when no fds are
130 changed.
131
Mark Dickinson82791672010-04-06 16:47:55 +0000132- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
133 on 64-bit machines. The shift count for either left or right shift is
134 permitted to be up to sys.maxsize.
135
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000136- Ensure that tokenization of identifiers is not affected by locale.

141
Eric Smithd44b2fc2010-04-02 12:30:56 +0000142- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
143 is called with a non-empty format string. This is an effort to
144 future-proof user code. If a derived class does not currently
145 implement __format__ but later adds its own __format__, it would
146 most likely break user code that had supplied a format string. This
147 will be changed to a DeprecationWaring in Python 3.3 and it will be
148 an error in Python 3.4.
149
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000150- Issue #8268: Old-style classes (not just instances) now support weak
151 references.

Victor Stinner6cbf90f2010-03-25 00:21:53 +0000153- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
154 optimizations are disabled when --with-pydebug is used.
155
Victor Stinnerc7790ed2010-03-22 12:36:28 +0000156- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +0000157

159 arguments to a function correct.
160

Georg Brandlba83f822010-03-14 09:50:54 +0000164 (SIGINT). If an error occurs while importing the site module, the error is
165 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000166 module.
167
Collin Winter001a3952010-03-18 21:54:01 +0000168- Code objects now support weak references.

174
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000175- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
176 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
177 and `ssl.OPENSSL_VERSION_NUMBER`.
178
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000179- Issue #8310: Allow dis to examine new style classes.
180
Mark Dickinson8a950712010-04-03 15:47:46 +0000181- Issue #8257: The Decimal construct now accepts a float instance
182 directly, converting that float to a Decimal of equal value:
183
184 >>> Decimal(1.1)

188
Raymond Hettingera551f312010-04-04 18:34:45 +0000189- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000190 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000191
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000192- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000193 old-style comparison functions to new-style key-functions.
194
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000195- Issue #8294: The Fraction constructor now accepts Decimal and float
196 instances directly.
197
Mark Dickinsone096e822010-04-02 10:17:07 +0000198- Issue #7279: Comparisons involving a Decimal signaling NaN now
199 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000200 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
201 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000202
Mark Dickinson99d80962010-04-02 08:53:22 +0000203- Issue #2531: Comparison operations between floats and Decimal
204 instances now return a result based on the numeric values of the

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000208- Issue #8233: When run as a script, py_compile.py optionally takes a single
209 argument `-` which tells it to read files to compile from stdin. Each line
210 is read on demand and the named file is compiled immediately. (Original
211 patch by Piotr Ożarowski).
212
213- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
214 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000215
Florent Xicluna58b65662010-03-30 16:29:03 +0000216- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
217 form feed (0x0C) are now considered linebreaks, as specified in Unicode
218 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000219 http://www.unicode.org/reports/tr14/
220
Mark Dickinson9588d992010-03-27 11:14:37 +0000221- Comparisons using one of <, <=, >, >= between a complex instance and
222 a Fractions instance now raise TypeError instead of returning
223 True/False. This makes Fraction <=> complex comparisons consistent with
224 int <=> complex, float <=> complex, and complex <=> complex comparisons.
225
Michael Foorde6410c52010-03-29 20:04:23 +0000226- Addition of ``WeakSet`` to the ``weakref`` module.

237 now silenced.
238
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000239- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

293 a base64 transfer-encoded payload *after* decoding it; it no longer does.
294 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000321- Issue #8300: When passing a non-integer argument to struct.pack with any
322 integer format code, struct.pack first attempts to convert the non-integer
323 using its __index__ method. If that method is non-existent or raises
324 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +0000326- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
327 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
328 argument's __int__ method to convert to an integer before packing. It also
329 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
330 was inconsistent: __int__ was used for some integer codes but not for others,
331 and the set of integer codes for which it was used differed between native
332 packing and standard packing.)

557 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000558 library would return a bogus result; on Solaris, it was possible to crash the
559 interpreter. Patch by Stefan Krah.

570 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +0000571
Georg Brandlba83f822010-03-14 09:50:54 +0000572- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
573 and add the additional members returned in an OSVERSIONINFOEX structure. The
574 new members are service_pack_major, service_pack_minor, suite_mask, and
575 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000577- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
578 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
579 returning NULL. The macro now returns a statically allocated empty string
580 instead.

590 strings,
591 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
592 numeric strings corresponding to subnormal values,
593 (3) a memory leak for some values large enough to cause overflow, and
594 (4) a number of flaws that could lead to incorrectly rounded results.
595

609 interpreter shutdown.
610
Georg Brandlba83f822010-03-14 09:50:54 +0000611- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
612 XML processing instructions and comments. These raw characters are allowed
613 by the XML specification, and are necessary when outputting e.g. PHP code in
614 a processing instruction. Patch by Neil Muller.

Vinay Sajip0e6e97d2010-02-04 20:23:45 +0000621
Antoine Pitroud840e512010-02-04 20:20:18 +0000622- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000623 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000624 Also, raise ValueError rather than TypeError when an unknown TIPC address
625 type is specified. Patch by Brian Curtin.
626
Vinay Sajip28c382f2010-02-04 18:48:53 +0000627- logging: Implemented PEP 391.
628
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000629- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000630 file position when calling `truncate()`. It would previously change the file
631 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000632 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
633
Benjamin Petersone06f7112010-01-28 02:15:02 +0000634- UserDict is now a new-style class.
635
Georg Brandlba83f822010-03-14 09:50:54 +0000636- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
637 class used to represent files stored inside an archive. The new
638 implementation is significantly faster and can be wrapped in a
639 ``io.BufferedReader`` object for more speedups. It also solves an issue
640 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
641 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +0000642
Benjamin Peterson2deb5c72010-01-27 02:16:42 +0000643- Issue #7792: Registering non-classes to ABCs raised an obscure error.

Georg Brandlba83f822010-03-14 09:50:54 +0000648- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
649 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000650
Georg Brandlba83f822010-03-14 09:50:54 +0000651- Issue #7748: Since unicode values are supported for some metadata options in
652 Distutils, the DistributionMetadata get_* methods will now return an utf-8
653 encoded string for them. This ensures that the upload and register commands
654 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000655
Georg Brandlba83f822010-03-14 09:50:54 +0000656- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000657 headers in multipart/signed MIME parts, which fixes one of the sources of
658 invalid modifications to such parts by Generator.

728Core and Builtins
729-----------------
730
Georg Brandlba83f822010-03-14 09:50:54 +0000731- The ``__complex__()`` method is now looked up on the class of instances to
732 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000733
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000734- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
735 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
736
Mark Dickinson1b34d252010-01-01 17:27:30 +0000737- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000738 DeprecationWarning when passed a float argument where an integer was expected.
739 These functions and methods now raise TypeError instead. The majority of the
740 effects of this change are in the extension modules, but some core functions
741 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
742 and many unicode/str methods.

754
Georg Brandlba83f822010-03-14 09:50:54 +0000755- Issue #1811: Improve accuracy and cross-platform consistency for true division
756 of integers: the result of a/b is now correctly rounded for ints a and b (at
757 least on IEEE 754 platforms), and in particular does not depend on the
758 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000759

Ronald Oussoren92919a62009-12-24 13:30:58 +0000765 executables on OSX.
766
Georg Brandlba83f822010-03-14 09:50:54 +0000767 These executables now work properly with the arch(1) command: ``arch -ppc
768 python`` will start a universal binary version of python in PPC mode (unlike
769 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000770

909 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000910
Georg Brandlba83f822010-03-14 09:50:54 +0000911- Remove switch from "%f" formatting to "%g" formatting for floats larger than
912 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000913

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000924
Georg Brandlba83f822010-03-14 09:50:54 +0000925- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
926 decimal string that's guaranteed to round back to x under correct rounding
927 (with round-half-to-even rounding mode). Previously it gave a string based on
928 rounding x to 17 decimal digits. repr(x) for a complex number behaves
929 similarly. On platforms where the correctly-rounded strtod and dtoa code is
930 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000931
Georg Brandlba83f822010-03-14 09:50:54 +0000932- Issue #7117: On almost all platforms: float-to-string and string-to-float
933 conversions within Python are now correctly rounded. Places these conversions
934 occur include: str for floats and complex numbers; the float and complex
935 constructors; old-style and new-style numeric formatting; serialization and
936 deserialization of floats and complex numbers using marshal, pickle and json;
937 parsing of float and imaginary literals in Python code; Decimal-to-float
938 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000939
Georg Brandlba83f822010-03-14 09:50:54 +0000940 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
941 providing correctly-rounded strtod and dtoa C functions. This code is
942 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
943 the C compiler. There may be a small number of platforms on which correct
944 operation of this code cannot be guaranteed, so the code is not used: notably,
945 this applies to platforms where the C double format is not IEEE 754 binary64,
946 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
947 and Python's configure script is unable to determine how to change the FPU
948 precision. On these platforms conversions use the platform strtod and dtoa,
949 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000951- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
952 uses the correctly-rounded string <-> float conversions described above (when
953 available), and so produces correctly rounded results that will display nicely
954 under the float repr. There are two related small changes: (1) round now
955 accepts any class with an ``__index__()`` method for its second argument (but
956 no longer accepts floats for the second argument), and (2) an excessively
957 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
958 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001101 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1102 (2) parsing of strings representing infinities and nans was locale aware; and
1103 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001105- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1106 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1107 but with at least one decimal point and with a default precision
1108 of 12. Previously, the behavior the same but with a default precision of 6.
1109 This more closely matches ``str()``, and reduces surprises when adding
1110 alignment flags to the empty presentation type. This also affects the new
1111 complex.__format__ in the same way.

Skip Montanarof205c132008-12-23 03:30:15 +00001277- Added test case to ensure attempts to read from a file opened for writing

Georg Brandlba83f822010-03-14 09:50:54 +00001294- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1295 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1296 instances. On a typical machine this saves 3 bytes of memory (on average) per
1297 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001299- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1300 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1301 instead of throwing a MemoryError.
1302
Georg Brandlba83f822010-03-14 09:50:54 +00001303- Issue #3689: The list reversed iterator now supports __length_hint__ instead

1308
Georg Brandlba83f822010-03-14 09:50:54 +00001309- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1310 file objects with closefd=False. The file descriptor is still kept open but
1311 the file object behaves like a closed file. The ``FileIO`` object also got a
1312 new readonly attribute ``closefd``.

1331
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001332- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001333 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00001335- On windows, ``os.chdir()`` given unicode was not working if
1336 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1337 this code path is really executed because I cannot move to such directory on
1338 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001340- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1341 element is temporarily replaced with an equivalent frozenset. But the
1342 eventual KeyError would always report the empty ``frozenset()`` as the missing
1343 key. Now it correctly refers to the initial element.

1361 returned them on 64bit platforms.
1362
Walter Dörwalded960ac2009-05-03 22:36:33 +00001363- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1364 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1365 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1366 of using the replace error handler in PyUnicode_DecodeUTF8().
1367
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001368- Issue #3739: The unicode-internal encoder now reports the number of characters

1370
Georg Brandlba83f822010-03-14 09:50:54 +00001371- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1372 allocator will be automatically disabled when running under Valgrind. This
1373 gives improved memory leak detection when running under Valgrind, while taking
1374 advantage of pymalloc at other times.

2740
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002741- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2742 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2743 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2744 ``printf`` function, whereas PyString_FromFormat has an independent
2745 implementation and uses "%zd" on all platforms for size_t values.
2746 This makes a difference on win64, where ``printf`` needs "%Id" to display
2747 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002749- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2753 object; previously an int would be returned for small values. the __long__
2754 method is allowed to return either an int or a long, but the behaviour of
2755 float objects should not change to respect backward compatibility.
2756
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002757- Issue #3751: str.rpartition would perform a left-partition when called with
2758 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002763 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002764 was correctly parsed but parsing of subsequent arguments failed.
2765
Vinay Sajip35e3b032008-09-01 14:33:59 +00002766- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002767 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2768 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2769 when given a tuple of classes as second argument, were looking up
2770 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2771 type object.
2772
Neal Norwitz18aa3882008-08-24 05:04:52 +00002773- Fix crashes on memory allocation failure found with failmalloc.

2916-----------------
2917
Guido van Rossumf8402962008-08-20 15:01:50 +00002918- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2919 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2920 extensions do not automatically benefit from the class attribute
2921 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2922 to their tp_flags field if they care. This is a backwards
2923 compatibility feature; in 3.0, all types will use the cache by
2924 default.
2925
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002926- Keyword arguments can now follow starred arguments. (``f(a, *args,

Thomas Heller0ad5ae02008-08-19 19:25:04 +00002929- ctypes function pointers that are COM methods have a boolean True
2930 value again.
2931
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002932- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2933 by denying s# to parse objects that have a releasebuffer procedure,
2934 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00002936- Issue #3537: Fix an assertion failure when an empty but presized dict
2937 object was stored in the freelist.
2938
Mark Dickinsonb6467572008-08-04 21:30:09 +00002939- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2940 ValueError consistently across platforms.
2941
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002942- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2943 (64bit Unix, for example), unichr() would truncate its argument and return
2944 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2945
Neal Norwitze7d8be82008-07-31 17:17:14 +00002946- Apply security patches from Apple.
2947
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002948- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2949 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2950
Antoine Pitrou92f82162008-07-25 22:22:08 +00002951- Issue #1819: function calls with several named parameters are now on
2952 average 35% faster (as measured by pybench).
2953
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002954- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2955 the python debugger steps into a class statement: the free variables (local
2956 variables defined in an outer scope) would be deleted from the outer scope.
2957
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002958- Issue #2620: Overflow checking when allocating or reallocating memory
2959 was not always being done properly in some python types and extension
2960 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2961 all been updated to perform better checks and places in the code that
2962 would previously leak memory on the error path when such an allocation
2963 failed have been fixed.

2972
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002973- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2974 version reported by these tools does not necessarily follow the python
2975 version numbering scheme, so the module is less strict when parsing it.
2976
Nick Coghlanf70385a2008-08-18 12:42:46 +00002977- Issue #2235: Added Py3k warnings for types which will become unhashable
2978 under the stricter __hash__ inheritance rules in 3.0. Several types
2979 which did not meet the rules for hash invariants and were already
2980 unhashable in 3.0 have now been explicitly flagged as unhashable in
2981 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2982 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2983
Brett Cannon88f801d2008-08-18 00:46:22 +00002984- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002993- Issue #3575: Incremental decoder's decode function now takes bytearray
2994 by using 's*' instead of 't#'.
2995
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002996- Issue #2222: Fixed reference leak when occurred os.rename()

Facundo Batistaeb90b782008-08-16 14:44:07 +00003005- Issue #2776: fixed small issue when handling an URL with double slash
3006 after a 302 response in the case of not going through a proxy.
3007
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003008- Issue #2676: in the email package, content-type parsing was hanging on
3009 pathological input because of quadratic or exponential behaviour of a
3010 regular expression.
3011
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003012- Issue #3476: binary buffered reading through the new "io" library is now
3013 thread-safe.
3014
Brett Cannonbf3157b2008-08-14 05:00:03 +00003015- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3016 since mimetools itself is deprecated. Because modules are cached, all
3017 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3018
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003019- Issue #3134: shutil referenced undefined WindowsError symbol.

Brett Cannon83e81842008-08-09 23:30:55 +00003024- Copied the implementation of reduce() to _functools.reduce() to have a
3025 version that did not raise a DeprecationWarning under -3.
3026
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003027- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3028 a MemoryError rather than silently stop the iteration.
3029
Guido van Rossum59ce9012008-08-09 14:55:34 +00003030- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3031 to _sre.compile() will now be rejected. This should not affect anybody
3032 since the re.compile() function never generates invalid re-bytecode.
3033
Skip Montanaroa032bf42008-08-08 22:52:51 +00003034- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3035 upon first access it can be automatically initialized from the csv file if
3036 it wasn't initialized during instantiation.
3037
Brett Cannon3aa2a492008-08-06 22:28:09 +00003038- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3039 the reload() built-in has been removed.
3040
Brett Cannon7e30b672008-08-04 21:52:25 +00003041- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003042 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3050 raised an AttributeError.
3051
Benjamin Peterson01a24322008-07-28 23:35:27 +00003052- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003053 asking for a specific length. This problem only affected files opened
3054 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003055

3078
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003079- Issue #3394: zipfile.writestr sets external attributes when passed a
3080 file name rather than a ZipInfo instance, so files are extracted with
3081 mode 0600 rather than 000 under Unix.
3082
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003083- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3084 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003095- Issue #2235: the C API function PyObject_HashNotImplemented and its
3096 interaction with the tp_hash slot (added in 2.6b2) are now documented
3097
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003098- Issue #643841: The language reference now provides more detailed
3099 coverage of the lookup process for special methods. The disclaimers
3100 regarding lack of coverage of new-style classes have also been
3101 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003109Core and Builtins
3110-----------------
3111
Georg Brandl3e483f62008-07-16 22:57:41 +00003112- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3113 its methods now allow for items objects that can be converted to
3114 an integer using operator.index().
3115
Mark Dickinson64b7e502008-07-16 09:40:03 +00003116- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3117 produced a ValueError instead of giving the correct float.
3118
Eric Smitha5fa5a22008-07-16 00:11:49 +00003119- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3120 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3121
Mark Dickinson7103aa42008-07-15 19:08:33 +00003122- Issue #3008: the float type has a new instance method 'float.hex'
3123 and a new class method 'float.fromhex' to convert floating-point
3124 numbers to and from hexadecimal strings, respectively.
3125
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003126- Issue #2235: __hash__ is once again inherited by default. To allow
3127 collections.Hashable to remain meaningful in the presence of the
3128 default hash implementation (object.__hash__), it is now possible
3129 to explicit block inheritance of hash by setting __hash__=None at
3130 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3131 level.
3132
Nick Coghlanb028f502008-07-13 14:52:36 +00003133- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3134 the parent module cannot be found while performing an absolute import.
3135 This means that an incorrectly defined __package__ attribute will
3136 now only prevent relative imports in that module rather than causing
3137 all imports from that module to fail.
3138
Nick Coghlan14ff9942008-07-08 14:21:42 +00003139- Issue #2517: Allow unicode messages in Exceptions again by correctly
3140 bypassing the instance dictionary when looking up __unicode__ on
3141 new-style classes.
3142
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003143- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3144 set to a custom object whose write() method happens to install
3145 another file in sys.stdout.
3146
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003147- Issue #3088: Corrected a race condition in classes derived from
3148 threading.local: the first member set by a thread could be saved in
3149 another thread's dictionary.
3150
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003151- Issue #3004: Minor change to slice.indices(): the start and stop
3152 arguments are now treated identically, making the behaviour easier
3153 to describe and understand. For example, slice(None, -10,
3154 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3155 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3156 10, -1).
3157
Georg Brandl278fc502008-07-19 12:46:12 +00003158- Issue #3219: Calling a function with repeated keyword arguments,
3159 f(a=2, a=23), would not cause a syntax error. This was a regression
3160 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003161
Georg Brandl278fc502008-07-19 12:46:12 +00003162- Issue #2862: Make int and float freelist management consistent with
3163 other freelists. Changes their CompactFreeList apis into
3164 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003165

3167-------
3168
Thomas Heller57adf222008-08-14 19:10:48 +00003169- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3170 api functions without holding the GIL, which could lead to a fatal
3171 error when they failed.
3172
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003173- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3182 ForkingPickler.register() to resolve conflict with ctypes.
3183
Vinay Sajip51e65192008-07-18 09:01:10 +00003184- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

3187 a valid dlerror() message.
3188
Thomas Heller2bad6572008-07-15 17:19:50 +00003189- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3190 incomplete structure was created.
3191
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003192- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00003194- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3195
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003196- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003197
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003198- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3199 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003200 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003201 content-length. The problem had been corrected in the 2.4 branch, but never
3202 merged into trunk.
3203
Georg Brandle78fbcc2008-07-05 10:13:36 +00003204- Issue #2663: add filtering capability to shutil.copytree().

3609 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003610 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003611
3612 This is controlled by the configure argument ``--with-universal-archs``:
3613
3614 - ``--with-universal-archs=all``: install 4-way universal
3615
3616 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3617
3618 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3619
3620 This option should be used in combination with ``--enable-universalsdk=``.
3621
3622 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003672- Issue #1631171: Re-implement the 'warnings' module in C (the
3673 original Python code has been kept as backup). This will allow for
3674 using the 'warning's machinery in such places as the parser where
3675 use of pure Python code is not possible. Both the ``showarning()``
3676 and ``formatwarning()`` gain an optional 'line' argument which is
3677 not called by default for backwards-compatibility reasons. Setting
3678 ``warnings.showwarning()`` to an implementation that lacks support
3679 for the ``line`` argument will raise a DeprecationWarning.

3703
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003704- The getpass module has been improved on Unix. It now uses /dev/tty
3705 by default and uses stderr instead of stdout. A GetPassWarning is
3706 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003721- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003722 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003742- Issue #2550: The approach used by client/server code for obtaining
3743 ports to listen on in network-oriented tests has been refined in an
3744 effort to facilitate running multiple instances of the entire
3745 regression test suite in parallel without issue.
3746 test_support.bind_port() has been fixed such that it will always
3747 return a unique port -- which wasn't always the case with the
3748 previous implementation, especially if socket options had been set
3749 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3750 new implementation of bind_port() will actually raise an exception
3751 if it is passed an AF_INET/SOCK_STREAM socket with either the
3752 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3753 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3754 the socket it's been passed. This currently only applies to
3755 Windows. This option prevents any other sockets from binding to the
3756 host/port we've bound to, thus removing the possibility of the
3757 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3758 when a second SOCK_STREAM socket binds and accepts to a host/port
3759 that's already been bound by another socket. The optional preferred
3760 port parameter to bind_port() has been removed. Under no
3761 circumstances should tests be hard coding ports!
3762
3763 test_support.find_unused_port() has also been introduced, which will
3764 pass a temporary socket object to bind_port() in order to obtain an
3765 unused port. The temporary socket object is then closed and
3766 deleted, and the port is returned. This method should only be used
3767 for obtaining an unused port in order to pass to an external program
3768 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3769 a parameter to a server-oriented class that doesn't give you direct
3770 access to the underlying socket used.
3771
3772 Finally, test_support.HOST has been introduced, which should be used
3773 for the host argument of any relevant socket calls (i.e. bind and
3774 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003775

4048Core and builtins
4049-----------------
4050
Fred Drakea8ee94b2008-03-01 02:45:07 +00004051- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004052 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004053
Georg Brandlad61bc82008-02-23 15:11:18 +00004054- Issue #2067: file.__exit__() now calls subclasses' close() method.
4055
4056- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004057
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004058- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004059 issue 215555 for a discussion.
4060
Eric Smitha73fbe72008-02-23 03:09:44 +00004061- Added the future_builtins module, which contains hex() and oct().
4062 These are the PEP 3127 version of these functions, designed to be
4063 compatible with the hex() and oct() builtins from Python 3.0. They
4064 differ slightly in their output formats from the existing, unchanged
4065 Python 2.6 builtins. The expected usage of the future_builtins
4066 module is:
4067 from future_builtins import hex, oct
4068
Eric Smith7ef40bf2008-02-20 23:34:22 +00004069- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4070 exponents for exponents with absolute value < 100. Follows C99
4071 standard. This is a change on Windows, which would use 3 digits.
4072 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4073 so that any alterations it does to the resulting string will be
4074 available in stringlib/formatter.h (for float.__format__).
4075
Eric Smith5a3c1352008-02-19 13:21:56 +00004076- Implemented PEP 3101, Advanced String Formatting. This adds a new
4077 builtin format(); a format() method for str and unicode; a
4078 __format__() method to object, str, unicode, int, long, float, and
4079 datetime; the class string.Formatter; and the C API
4080 PyObject_Format().
4081
Georg Brandl3ee81df2008-05-17 18:14:43 +00004082- Fixed several potential crashes, all caused by specially crafted
4083 __del__ methods exploiting objects in temporarily inconsistent
4084 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004085
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004086- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004087 prevent a possible crash: an Abstract Base Class would try to access
4088 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004089
Georg Brandl3ee81df2008-05-17 18:14:43 +00004090- Fixed repr() and str() of complex numbers with infinity or nan as
4091 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004092
Georg Brandl3ee81df2008-05-17 18:14:43 +00004093- Clear all free lists during a gc.collect() of the highest generation
4094 in order to allow pymalloc to free more arenas. Python may give back
4095 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004096
Georg Brandl3ee81df2008-05-17 18:14:43 +00004097- Issue #2045: Fix an infinite recursion triggered when printing a
4098 subclass of collections.defaultdict, if its default_factory is set
4099 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004100
Christian Heimesf75dbef2008-02-08 00:11:31 +00004101- Fixed a minor memory leak in dictobject.c. The content of the free
4102 list was not freed on interpreter shutdown.
4103
Georg Brandl21e99f42010-03-07 15:23:59 +00004104- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004105 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004106
Georg Brandl3ee81df2008-05-17 18:14:43 +00004107- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4108 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004109 to compact the internal free lists of pre-allocted ints and floats.
4110
Georg Brandl3ee81df2008-05-17 18:14:43 +00004111- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4112 calls. Python expected the return type int but the fork familie
4113 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004114
Georg Brandl3ee81df2008-05-17 18:14:43 +00004115- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4116 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004117
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4119 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004120
Georg Brandl3ee81df2008-05-17 18:14:43 +00004121- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4122 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004123
Georg Brandl3ee81df2008-05-17 18:14:43 +00004124- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4125 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004126
Georg Brandl3ee81df2008-05-17 18:14:43 +00004127- Patch #1473257: generator objects gain a gi_code attribute. This is
4128 the same object as the func_code attribute of the function that
4129 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004130
Georg Brandl3ee81df2008-05-17 18:14:43 +00004131- Issue #1920: "while 0" statements were completely removed by the
4132 compiler, even in the presence of an "else" clause, which is
4133 supposed to be run when the condition is false. Now the compiler
4134 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004135
Guido van Rossumeead05f2008-01-24 18:21:02 +00004136- A few crashers fixed: weakref_in_del.py (issue #1377858);
4137 loosing_dict_ref.py (issue #1303614, test67.py);
4138 borrowed_ref_[34].py (not in tracker).
4139
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004140- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004141 suppressed while an extension is loaded by calling SetErrorMode in
4142 dynload_win.c. The error is still reported properly.
4143
Georg Brandl3ee81df2008-05-17 18:14:43 +00004144- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004145 several extension methods and modules do not work without unicode
4146 support.
4147
Georg Brandl26543b12008-01-21 18:36:51 +00004148- Issue #1882: when compiling code from a string, encoding cookies in the
4149 second line of code were not always recognized correctly.
4150
Georg Brandl14404b62008-01-19 19:27:05 +00004151- Issue #1679: "0x" was taken as a valid integer literal.
4152
Georg Brandl6caad7d2008-01-26 14:19:22 +00004153- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004154 added.
4155
Christian Heimesc94e2b52008-01-14 04:13:37 +00004156- sys.float_info / PyFloat_GetInfo: The floating point information
4157 object was converted from a dict to a specialized structseq object.
4158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Patch #1816: Added sys.flags structseq. It exposes the status of
4160 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004161
Georg Brandl3ee81df2008-05-17 18:14:43 +00004162- Objects/structseq.c: Implemented new structseq representation. The
4163 patch makes structseqs (e.g. the return value of os.stat) more
4164 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004165
Georg Brandl3ee81df2008-05-17 18:14:43 +00004166- Patch #1700288: added a type attribute cache that caches method
4167 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004168
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004169- Bug #1776: __import__() no longer accepts filenames on any platform.
4170 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004171
Georg Brandlaed6c662008-01-07 17:25:53 +00004172- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4173
Georg Brandl3ee81df2008-05-17 18:14:43 +00004174- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4175 envvar and sys.dont_write_bytecode attribute. All these can be set
4176 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004177
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Improve some exception messages when Windows fails to load an
4179 extension module. Now we get for example '%1 is not a valid Win32
4180 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004181
Georg Brandl3ee81df2008-05-17 18:14:43 +00004182- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004184- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4185 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004186
Christian Heimes0a8143f2007-12-18 23:22:54 +00004187- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188 and INF. float("nan"), float("inf") and float("-inf") now work on
4189 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004190
Georg Brandl3ee81df2008-05-17 18:14:43 +00004191- Compiler now generates simpler and faster code for dictionary
4192 literals. The oparg for BUILD_MAP now indicates an estimated
4193 dictionary size. There is a new opcode, STORE_MAP, for adding
4194 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004195
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004198- Issue #1620: New property decorator syntax was modifying the
4199 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004200
Georg Brandl3ee81df2008-05-17 18:14:43 +00004201- Issue #1538: Avoid copying string in split/rsplit if the split char
4202 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004203
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004204- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004205 SystemError.
4206
Nick Coghlanef01d822007-12-03 12:55:17 +00004207- PEP 366: Allow explicit relative imports when executing modules
4208 inside packages with the -m switch via a new module level
4209 __package__ attribute.
4210
Georg Brandl3ee81df2008-05-17 18:14:43 +00004211- Issue #1402: Fix a crash on exit, when another thread is still
4212 running, and if the deallocation of its frames somehow calls the
4213 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004214

4216
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00004217- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004218 attribute of an empty cell object.
4219
Georg Brandl3ee81df2008-05-17 18:14:43 +00004220- Issue #1460: The utf-7 incremental decoder did not accept truncated
4221 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004222
Georg Brandl3ee81df2008-05-17 18:14:43 +00004223- Patch #1739468: Directories and zipfiles containing a __main__.py
4224 file can now be directly executed by passing their name to the
4225 interpreter. The directory/zipfile is automatically inserted as the
4226 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004227
Georg Brandl3ee81df2008-05-17 18:14:43 +00004228- Issue #1265: Fix a problem with sys.settrace, if the tracing
4229 function uses a generator expression when at the same time the
4230 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004231
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004232- sets and frozensets now have an isdisjoint() method.
4233
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004234- optimize the performance of builtin.sum().
4235
Neal Norwitz44f326e2007-10-05 05:29:17 +00004236- Fix warnings found by the new version of the Coverity checker.
4237
Georg Brandl21e99f42010-03-07 15:23:59 +00004238- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004239 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4240 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004241
Georg Brandl3ee81df2008-05-17 18:14:43 +00004242- Issue #1686386: Tuple's tp_repr did not take into account the
4243 possibility of having a self-referential tuple, which is possible
4244 from C code. Nor did object's tp_str consider that a type's tp_str
4245 could do something that could lead to an inifinite recursion.
4246 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4247 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004248
Georg Brandl3ee81df2008-05-17 18:14:43 +00004249- Issue #1164: It was possible to trigger deadlock when using the
4250 'print' statement to write to a file since the GIL was not released
4251 as needed. Now PyObject_Print() does the right thing along with
4252 various tp_print implementations of the built-in types and those in
4253 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004254
Georg Brandl3ee81df2008-05-17 18:14:43 +00004255- Issue #1147: Exceptions were directly allowing string exceptions in
4256 their throw() method even though string exceptions no longer
4257 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004258
Georg Brandl3ee81df2008-05-17 18:14:43 +00004259- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00004262- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004263 PyObject_Call() never calling back out to Python code to trigger
4264 recursion depth updates/checks. Required the creation of a static
4265 RuntimeError instance in case normalizing an exception put the
4266 recursion check value past its limit. Fixes crashers
4267 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004268
Georg Brandl3ee81df2008-05-17 18:14:43 +00004269- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004282- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004283 __*__ attributes. (Some already existed, e.g., __doc__ and
4284 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004285
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004286- Add -3 option to the interpreter to warn about features that are

4291
Collin Winter62903052007-05-18 23:11:24 +00004292- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004293 "except E as target:". This is to provide forwards compatibility
4294 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004295
Brett Cannon229cee22007-05-05 01:34:02 +00004296- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004301- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004302 setting a plain string, ie don't expand to single letter identifiers.
4303
Raymond Hettinger13936692007-04-11 18:40:58 +00004304- Request #1191699: Slices can now be pickled.
4305

4308 remaining characters.
4309
Georg Brandl5cb76c12007-03-21 09:00:39 +00004310- Patch #1682205: a TypeError while unpacking an iterable is no longer

4314
Guido van Rossum143b5642007-03-23 04:58:42 +00004315- Bug #1683368: The object.__init__() and object.__new__() methods are
4316 now stricter in rejecting excess arguments. The only time when
4317 either allows excess arguments is when it is not overridden and the
4318 other one is. For backwards compatibility, when both are
4319 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004320 warning later). Also, type.__init__() insists on the same signature
4321 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004322
Georg Brandl3ee81df2008-05-17 18:14:43 +00004323- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4324 object to complex using its __complex__() method before falling back
4325 to the __float__() method. Therefore, the functions in the cmath
4326 module now can operate on objects that define a __complex__()
4327 method.

4344
Georg Brandl7b9c5552007-03-12 14:30:05 +00004345- Bug #1678647: write a newline after printing an exception in any
4346 case, even when converting the value to a string failed.
4347
Georg Brandl871f1bc2007-03-12 13:17:36 +00004348- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004349 its argument, if it exists. If not, it will work like before. This
4350 allows customizing the output of dir() in the presence of a
4351 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004352
Collin Winter276887b2007-03-12 16:11:39 +00004353- Patch #922167: Python no longer segfaults when faced with infinitely
4354 self-recursive reload() calls (as reported by bug #742342).
4355

4360 parthensized forms. This means complex(repr(x)) now works instead of
4361 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004362
Georg Brandlaa2321b2007-03-07 00:40:28 +00004363- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004364 makes the filenames the warning module prints much more sensible
4365 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004366
Georg Brandl49aafc92007-03-07 00:34:46 +00004367- Variant of patch #697613: don't exit the interpreter on a SystemExit
4368 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004369 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00004378- Patch #1674228: when assigning a slice (old-style), check for the
4379 sq_ass_slice instead of the sq_slice slot.
4380
Georg Brandl3ee81df2008-05-17 18:14:43 +00004381- When printing an unraisable error, don't print exceptions. before
4382 the name. This duplicates the behavior whening normally printing
4383 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005007- unittest now verifies more of its assumptions. In particular,

5009 accepted in TestSuite.addTest(). This should cause no
5010 incompatibility since it never made sense with ordinary subclasses
5011 -- the failure just occurred later, with a more cumbersome
5012 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005293- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5294 with RFC 3207 and forgets any knowledge obtained from the server not
5295 obtained from the TLS negotiation itself. Patch contributed by Bill
5296 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005297
Georg Brandl3ee81df2008-05-17 18:14:43 +00005298- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005299 that the SMTP.starttls() caller no longer needs to call ehlo()
5300 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005301 does not claim to support starttls. Adds the
5302 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5383 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5384 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005401 time so that opening a database previously created with the DB_DUP
5402 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5403 opens. Specifically: dictionary assignment to a DB object will
5404 replace all values for a given key when the database allows
5405 duplicate values. DB users should use DB.put(k, v) when they want
5406 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005407

5413 characters with ASCII value less than 32. Also, it correctly quotes
5414 dots only if they occur on a single line, as opposed to the previous
5415 behavior of quoting dots if they are the second character of any
5416 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005741- Unified naming convention for free lists and their limits. All free
5742 lists in Object/ are named ``free_list``, the counter ``numfree``
5743 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5744 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005745
Georg Brandl3ee81df2008-05-17 18:14:43 +00005746- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5747 to ``PyTuple_SetItem``, it can be used to populate a brand new
5748 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005749
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005750- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005751
Georg Brandl3ee81df2008-05-17 18:14:43 +00005752- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5753 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5754 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005755
5756- Patch #1720595: add T_BOOL to the range of structmember types.
5757
5758- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5759 ``PyFloat_GetInfo()`` to the float API.
5760
Georg Brandl3ee81df2008-05-17 18:14:43 +00005761- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5762 of w# format code incorrectly truncated the length to an int, even
5763 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5764 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005765
Georg Brandl3ee81df2008-05-17 18:14:43 +00005766- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5767 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005768
Georg Brandl3ee81df2008-05-17 18:14:43 +00005769- PEP 3123: Provide forward compatibility with Python 3.0, while
5770 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5771 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005772
Georg Brandl3ee81df2008-05-17 18:14:43 +00005773- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5774 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005775
5776- Patch #1733960: Allow T_LONGLONG to accept ints.
5777
5778- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5779
Christian Heimes000a0742008-01-03 22:16:32 +00005780- Added a new API function ``PyImport_ImportModuleNoBlock``.
5781
Georg Brandl6caad7d2008-01-26 14:19:22 +00005782- Bug #1637022: Prefix AST symbols with _Py_.
5783
5784- Fix some leftovers from the conversion from int to Py_ssize_t
5785 (relevant to strings and sequences of more than 2**31 items).
5786
5787- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5788 outside of pystate.c and should not be necessary.
5789
Georg Brandl3ee81df2008-05-17 18:14:43 +00005790- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5791 absolute imports. In earlier versions they might have used relative
5792 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005793
Georg Brandl3ee81df2008-05-17 18:14:43 +00005794- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5795 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005796
Georg Brandl3ee81df2008-05-17 18:14:43 +00005797- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5798 macro so it can be used as an expression.

5803
Georg Brandl3ee81df2008-05-17 18:14:43 +00005804- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5805 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5806 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5807 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005808
Georg Brandl3ee81df2008-05-17 18:14:43 +00005809- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5810 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00005820- buildtools now raises a DeprecationWarning.
5821
Georg Brandl3ee81df2008-05-17 18:14:43 +00005822- Removed the macfs module. It had been deprecated since Python 2.5.
5823 This lead to the deprecation of macostools.touched() as it relied
5824 solely on macfs and was a no-op under OS X.
