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

Antoine Pitroua6240402010-04-25 21:40:32 +000033- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
34 where the method could block indefinitely if called just before the
35 event loop started running. This also fixes the occasional freezes
36 witnessed in test_httpservers.
37
Antoine Pitroufc69af12010-04-24 20:04:58 +000038- Issue #5103: SSL handshake would ignore the socket timeout and block
39 indefinitely if the other end didn't respond.
40
Antoine Pitrou4d3e3722010-04-24 19:57:01 +000041- The do_handshake() method of SSL objects now adjusts the blocking mode of
42 the SSL structure if necessary (as other methods already do).
43
Georg Brandl4341e542010-04-24 09:08:10 +000044- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.

54 and keywords.
55
Antoine Pitroua5c4b552010-04-22 23:33:02 +000056- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
57 a non-infinite timeout. Also make that method friendlier with applications
58 wanting to continue using the socket in clear-text mode, by disabling
59 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
60
Antoine Pitrouc715a9e2010-04-21 19:28:03 +000061- Issue #8484: Load all ciphers and digest algorithms when initializing
62 the _ssl extension, such that verification of some SSL certificates
63 doesn't fail because of an "unknown algorithm".
64

87 filename and date, conforming to the 'standards' they were originally
88 designed to follow. This improves compatibility with patch tools.
89
R. David Murray27ef9372010-04-12 14:26:06 +000090- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
91 character sets will now consistently use a Content-Transfer-Encoding of
92 7bit rather than sometimes being marked as 8bit.
93

121Core and Builtins
122-----------------
123
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000124- Issue #7301: Add environment variable $PYTHONWARNINGS.
125
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000126- Issue #8329: Don't return the same lists from select.select when no fds are
127 changed.
128
Mark Dickinson82791672010-04-06 16:47:55 +0000129- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
130 on 64-bit machines. The shift count for either left or right shift is
131 permitted to be up to sys.maxsize.
132
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000133- Ensure that tokenization of identifiers is not affected by locale.

138
Eric Smithd44b2fc2010-04-02 12:30:56 +0000139- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
140 is called with a non-empty format string. This is an effort to
141 future-proof user code. If a derived class does not currently
142 implement __format__ but later adds its own __format__, it would
143 most likely break user code that had supplied a format string. This
144 will be changed to a DeprecationWaring in Python 3.3 and it will be
145 an error in Python 3.4.
146
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000147- Issue #8268: Old-style classes (not just instances) now support weak
148 references.

Victor Stinner6cbf90f2010-03-25 00:21:53 +0000150- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
151 optimizations are disabled when --with-pydebug is used.
152
Victor Stinnerc7790ed2010-03-22 12:36:28 +0000153- Issue #1583863: An unicode subclass can now override the __unicode__ method

Georg Brandlba83f822010-03-14 09:50:54 +0000161 (SIGINT). If an error occurs while importing the site module, the error is
162 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000163 module.
164
Collin Winter001a3952010-03-18 21:54:01 +0000165- Code objects now support weak references.

171
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000172- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
173 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
174 and `ssl.OPENSSL_VERSION_NUMBER`.
175
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000176- Issue #8310: Allow dis to examine new style classes.
177
Mark Dickinson8a950712010-04-03 15:47:46 +0000178- Issue #8257: The Decimal construct now accepts a float instance
179 directly, converting that float to a Decimal of equal value:
180
181 >>> Decimal(1.1)
182 Decimal('1.100000000000000088817841970012523233890533447265625')

185
Raymond Hettingera551f312010-04-04 18:34:45 +0000186- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000187 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000188
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000189- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000190 old-style comparison functions to new-style key-functions.
191
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000192- Issue #8294: The Fraction constructor now accepts Decimal and float
193 instances directly.
194
Mark Dickinsone096e822010-04-02 10:17:07 +0000195- Issue #7279: Comparisons involving a Decimal signaling NaN now
196 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000197 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
198 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000199

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000205- Issue #8233: When run as a script, py_compile.py optionally takes a single
206 argument `-` which tells it to read files to compile from stdin. Each line
207 is read on demand and the named file is compiled immediately. (Original
208 patch by Piotr Ożarowski).
209
210- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
211 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000212
Florent Xicluna58b65662010-03-30 16:29:03 +0000213- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
214 form feed (0x0C) are now considered linebreaks, as specified in Unicode
215 Standard Annex #14. See issue #7643.

217
Mark Dickinson9588d992010-03-27 11:14:37 +0000218- Comparisons using one of <, <=, >, >= between a complex instance and
219 a Fractions instance now raise TypeError instead of returning
220 True/False. This makes Fraction <=> complex comparisons consistent with
221 int <=> complex, float <=> complex, and complex <=> complex comparisons.
222
Michael Foorde6410c52010-03-29 20:04:23 +0000223- Addition of ``WeakSet`` to the ``weakref`` module.

234 now silenced.
235
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000236- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

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

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000318- Issue #8300: When passing a non-integer argument to struct.pack with any
319 integer format code, struct.pack first attempts to convert the non-integer
320 using its __index__ method. If that method is non-existent or raises
321 TypeError it goes on to try the __int__ method, as described below.
322
Georg Brandlba83f822010-03-14 09:50:54 +0000323- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
324 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
325 argument's __int__ method to convert to an integer before packing. It also
326 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
327 was inconsistent: __int__ was used for some integer codes but not for others,
328 and the set of integer codes for which it was used differed between native
329 packing and standard packing.)

554 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000555 library would return a bogus result; on Solaris, it was possible to crash the
556 interpreter. Patch by Stefan Krah.

567 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +0000568
Georg Brandlba83f822010-03-14 09:50:54 +0000569- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
570 and add the additional members returned in an OSVERSIONINFOEX structure. The
571 new members are service_pack_major, service_pack_minor, suite_mask, and
572 product_type.
Eric Smithee931b72010-01-27 00:28:29 +0000573
Georg Brandlba83f822010-03-14 09:50:54 +0000574- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
575 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
576 returning NULL. The macro now returns a statically allocated empty string
577 instead.

Georg Brandlba83f822010-03-14 09:50:54 +0000586 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
587 strings,
588 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
589 numeric strings corresponding to subnormal values,
590 (3) a memory leak for some values large enough to cause overflow, and
591 (4) a number of flaws that could lead to incorrectly rounded results.
592
593- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
594 option is not used.
Brett Cannon6fdd3dc2010-01-10 02:56:19 +0000595

606 interpreter shutdown.
607
Georg Brandlba83f822010-03-14 09:50:54 +0000608- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
609 XML processing instructions and comments. These raw characters are allowed
610 by the XML specification, and are necessary when outputting e.g. PHP code in
611 a processing instruction. Patch by Neil Muller.
Antoine Pitrou42fb6ab2010-02-09 17:08:05 +0000612

Vinay Sajip0e6e97d2010-02-04 20:23:45 +0000618
Antoine Pitroud840e512010-02-04 20:20:18 +0000619- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000620 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000621 Also, raise ValueError rather than TypeError when an unknown TIPC address
622 type is specified. Patch by Brian Curtin.
623
Vinay Sajip28c382f2010-02-04 18:48:53 +0000624- logging: Implemented PEP 391.
625
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000626- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000627 file position when calling `truncate()`. It would previously change the file
628 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000629 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
630
Benjamin Petersone06f7112010-01-28 02:15:02 +0000631- UserDict is now a new-style class.
632
Georg Brandlba83f822010-03-14 09:50:54 +0000633- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
634 class used to represent files stored inside an archive. The new
635 implementation is significantly faster and can be wrapped in a
636 ``io.BufferedReader`` object for more speedups. It also solves an issue
637 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
638 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +0000639
Benjamin Peterson2deb5c72010-01-27 02:16:42 +0000640- Issue #7792: Registering non-classes to ABCs raised an obscure error.
641

Georg Brandlba83f822010-03-14 09:50:54 +0000645- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
646 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000647
Georg Brandlba83f822010-03-14 09:50:54 +0000648- Issue #7748: Since unicode values are supported for some metadata options in
649 Distutils, the DistributionMetadata get_* methods will now return an utf-8
650 encoded string for them. This ensures that the upload and register commands
651 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000652
Georg Brandlba83f822010-03-14 09:50:54 +0000653- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000654 headers in multipart/signed MIME parts, which fixes one of the sources of
655 invalid modifications to such parts by Generator.

725Core and Builtins
726-----------------
727
Georg Brandlba83f822010-03-14 09:50:54 +0000728- The ``__complex__()`` method is now looked up on the class of instances to
729 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000730
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000731- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
732 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
733
Mark Dickinson1b34d252010-01-01 17:27:30 +0000734- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000735 DeprecationWarning when passed a float argument where an integer was expected.
736 These functions and methods now raise TypeError instead. The majority of the
737 effects of this change are in the extension modules, but some core functions
738 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
739 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000752- Issue #1811: Improve accuracy and cross-platform consistency for true division
753 of integers: the result of a/b is now correctly rounded for ints a and b (at
754 least on IEEE 754 platforms), and in particular does not depend on the
755 internal representation of a long.

763
Georg Brandlba83f822010-03-14 09:50:54 +0000764 These executables now work properly with the arch(1) command: ``arch -ppc
765 python`` will start a universal binary version of python in PPC mode (unlike
766 previous releases).

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000921
Georg Brandlba83f822010-03-14 09:50:54 +0000922- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
923 decimal string that's guaranteed to round back to x under correct rounding
924 (with round-half-to-even rounding mode). Previously it gave a string based on
925 rounding x to 17 decimal digits. repr(x) for a complex number behaves
926 similarly. On platforms where the correctly-rounded strtod and dtoa code is
927 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000928
Georg Brandlba83f822010-03-14 09:50:54 +0000929- Issue #7117: On almost all platforms: float-to-string and string-to-float
930 conversions within Python are now correctly rounded. Places these conversions
931 occur include: str for floats and complex numbers; the float and complex
932 constructors; old-style and new-style numeric formatting; serialization and
933 deserialization of floats and complex numbers using marshal, pickle and json;
934 parsing of float and imaginary literals in Python code; Decimal-to-float
935 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000936
Georg Brandlba83f822010-03-14 09:50:54 +0000937 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
938 providing correctly-rounded strtod and dtoa C functions. This code is
939 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
940 the C compiler. There may be a small number of platforms on which correct
941 operation of this code cannot be guaranteed, so the code is not used: notably,
942 this applies to platforms where the C double format is not IEEE 754 binary64,
943 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
944 and Python's configure script is unable to determine how to change the FPU
945 precision. On these platforms conversions use the platform strtod and dtoa,
946 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000948- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
949 uses the correctly-rounded string <-> float conversions described above (when
950 available), and so produces correctly rounded results that will display nicely
951 under the float repr. There are two related small changes: (1) round now
952 accepts any class with an ``__index__()`` method for its second argument (but
953 no longer accepts floats for the second argument), and (2) an excessively
954 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
955 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001097
Georg Brandlba83f822010-03-14 09:50:54 +00001098 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1099 (2) parsing of strings representing infinities and nans was locale aware; and
1100 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00001101
Georg Brandlba83f822010-03-14 09:50:54 +00001102- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1103 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1104 but with at least one decimal point and with a default precision
1105 of 12. Previously, the behavior the same but with a default precision of 6.
1106 This more closely matches ``str()``, and reduces surprises when adding
1107 alignment flags to the empty presentation type. This also affects the new
1108 complex.__format__ in the same way.
1109
1110- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1111 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00001173 untrackable objects are not tracked by the garbage collector. This can reduce
1174 the size of collections and therefore the garbage collection overhead on

1182 internal representation of integers, for performance reasons. Base 2**30 is
1183 enabled by default on 64-bit machines. Add --enable-big-digits option to
1184 configure, which overrides the default. Add sys.long_info structseq to
1185 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00001306- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1307 file objects with closefd=False. The file descriptor is still kept open but
1308 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00001332- On windows, ``os.chdir()`` given unicode was not working if
1333 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1334 this code path is really executed because I cannot move to such directory on
1335 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001337- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1338 element is temporarily replaced with an equivalent frozenset. But the
1339 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00001360- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1361 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1362 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1363 of using the replace error handler in PyUnicode_DecodeUTF8().
1364
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001365- Issue #3739: The unicode-internal encoder now reports the number of characters

1367
Georg Brandlba83f822010-03-14 09:50:54 +00001368- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1370 gives improved memory leak detection when running under Valgrind, while taking
1371 advantage of pymalloc at other times.

2538 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2539 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002736- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2737
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002738- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2739 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2740 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2741 ``printf`` function, whereas PyString_FromFormat has an independent
2742 implementation and uses "%zd" on all platforms for size_t values.
2743 This makes a difference on win64, where ``printf`` needs "%Id" to display
2744 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002746- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2750 object; previously an int would be returned for small values. the __long__
2751 method is allowed to return either an int or a long, but the behaviour of
2752 float objects should not change to respect backward compatibility.
2753
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002754- Issue #3751: str.rpartition would perform a left-partition when called with
2755 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002760 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002761 was correctly parsed but parsing of subsequent arguments failed.
2762
Vinay Sajip35e3b032008-09-01 14:33:59 +00002763- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002764 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2765 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2766 when given a tuple of classes as second argument, were looking up
2767 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2768 type object.
2769
Neal Norwitz18aa3882008-08-24 05:04:52 +00002770- Fix crashes on memory allocation failure found with failmalloc.

2839 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2840 for catch_warnings() also led to an improvement in the raising of a

2913-----------------
2914
Guido van Rossumf8402962008-08-20 15:01:50 +00002915- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2916 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2917 extensions do not automatically benefit from the class attribute
2918 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2919 to their tp_flags field if they care. This is a backwards
2920 compatibility feature; in 3.0, all types will use the cache by
2921 default.
2922
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002923- Keyword arguments can now follow starred arguments. (``f(a, *args,
2924 keyword=23)`` is now valid syntax.)
2925
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002926- ctypes function pointers that are COM methods have a boolean True

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002929- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2930 by denying s# to parse objects that have a releasebuffer procedure,
2931 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00002933- Issue #3537: Fix an assertion failure when an empty but presized dict
2934 object was stored in the freelist.
2935
Mark Dickinsonb6467572008-08-04 21:30:09 +00002936- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2937 ValueError consistently across platforms.
2938
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002939- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2940 (64bit Unix, for example), unichr() would truncate its argument and return
2941 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2942
Neal Norwitze7d8be82008-07-31 17:17:14 +00002943- Apply security patches from Apple.
2944
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002945- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2946 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2947
Antoine Pitrou92f82162008-07-25 22:22:08 +00002948- Issue #1819: function calls with several named parameters are now on
2949 average 35% faster (as measured by pybench).
2950
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002951- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2952 the python debugger steps into a class statement: the free variables (local
2953 variables defined in an outer scope) would be deleted from the outer scope.
2954
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002955- Issue #2620: Overflow checking when allocating or reallocating memory
2956 was not always being done properly in some python types and extension
2957 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2958 all been updated to perform better checks and places in the code that
2959 would previously leak memory on the error path when such an allocation
2960 failed have been fixed.

2969
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002970- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2971 version reported by these tools does not necessarily follow the python
2972 version numbering scheme, so the module is less strict when parsing it.
2973
Nick Coghlanf70385a2008-08-18 12:42:46 +00002974- Issue #2235: Added Py3k warnings for types which will become unhashable
2975 under the stricter __hash__ inheritance rules in 3.0. Several types
2976 which did not meet the rules for hash invariants and were already
2977 unhashable in 3.0 have now been explicitly flagged as unhashable in
2978 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2979 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2980
Brett Cannon88f801d2008-08-18 00:46:22 +00002981- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00003012- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3013 since mimetools itself is deprecated. Because modules are cached, all
3014 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3015
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003016- Issue #3134: shutil referenced undefined WindowsError symbol.

3028 to _sre.compile() will now be rejected. This should not affect anybody
3029 since the re.compile() function never generates invalid re-bytecode.

Skip Montanaroa032bf42008-08-08 22:52:51 +00003031- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3032 upon first access it can be automatically initialized from the csv file if
3033 it wasn't initialized during instantiation.
3034
Brett Cannon3aa2a492008-08-06 22:28:09 +00003035- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3036 the reload() built-in has been removed.
3037
Brett Cannon7e30b672008-08-04 21:52:25 +00003038- Changed code in the following modules/packages to remove warnings raised

Benjamin Peterson01a24322008-07-28 23:35:27 +00003049- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003050 asking for a specific length. This problem only affected files opened
3051 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003052

3075
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003076- Issue #3394: zipfile.writestr sets external attributes when passed a
3077 file name rather than a ZipInfo instance, so files are extracted with
3078 mode 0600 rather than 000 under Unix.
3079
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003080- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3081 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003092- Issue #2235: the C API function PyObject_HashNotImplemented and its
3093 interaction with the tp_hash slot (added in 2.6b2) are now documented
3094
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003095- Issue #643841: The language reference now provides more detailed
3096 coverage of the lookup process for special methods. The disclaimers
3097 regarding lack of coverage of new-style classes have also been
3098 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003106Core and Builtins
3107-----------------
3108
Georg Brandl3e483f62008-07-16 22:57:41 +00003109- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3110 its methods now allow for items objects that can be converted to
3111 an integer using operator.index().
3112
Mark Dickinson64b7e502008-07-16 09:40:03 +00003113- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3114 produced a ValueError instead of giving the correct float.
3115
Eric Smitha5fa5a22008-07-16 00:11:49 +00003116- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3117 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3118
Mark Dickinson7103aa42008-07-15 19:08:33 +00003119- Issue #3008: the float type has a new instance method 'float.hex'
3120 and a new class method 'float.fromhex' to convert floating-point
3121 numbers to and from hexadecimal strings, respectively.
3122
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003123- Issue #2235: __hash__ is once again inherited by default. To allow
3124 collections.Hashable to remain meaningful in the presence of the
3125 default hash implementation (object.__hash__), it is now possible
3126 to explicit block inheritance of hash by setting __hash__=None at
3127 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3128 level.
3129
Nick Coghlanb028f502008-07-13 14:52:36 +00003130- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3131 the parent module cannot be found while performing an absolute import.
3132 This means that an incorrectly defined __package__ attribute will
3133 now only prevent relative imports in that module rather than causing
3134 all imports from that module to fail.
3135
Nick Coghlan14ff9942008-07-08 14:21:42 +00003136- Issue #2517: Allow unicode messages in Exceptions again by correctly
3137 bypassing the instance dictionary when looking up __unicode__ on
3138 new-style classes.
3139
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003140- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3141 set to a custom object whose write() method happens to install
3142 another file in sys.stdout.
3143
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003144- Issue #3088: Corrected a race condition in classes derived from
3145 threading.local: the first member set by a thread could be saved in
3146 another thread's dictionary.
3147
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003148- Issue #3004: Minor change to slice.indices(): the start and stop
3149 arguments are now treated identically, making the behaviour easier
3150 to describe and understand. For example, slice(None, -10,
3151 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3152 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3153 10, -1).
3154
Georg Brandl278fc502008-07-19 12:46:12 +00003155- Issue #3219: Calling a function with repeated keyword arguments,
3156 f(a=2, a=23), would not cause a syntax error. This was a regression
3157 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003158
Georg Brandl278fc502008-07-19 12:46:12 +00003159- Issue #2862: Make int and float freelist management consistent with
3160 other freelists. Changes their CompactFreeList apis into
3161 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003162

3164-------
3165
Thomas Heller57adf222008-08-14 19:10:48 +00003166- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3167 api functions without holding the GIL, which could lead to a fatal
3168 error when they failed.
3169
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003170- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3179 ForkingPickler.register() to resolve conflict with ctypes.
3180
Vinay Sajip51e65192008-07-18 09:01:10 +00003181- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003183- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3184 a valid dlerror() message.
3185
Thomas Heller2bad6572008-07-15 17:19:50 +00003186- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3187 incomplete structure was created.
3188
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003189- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00003191- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3192
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003193- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003194
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003195- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3196 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003197 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003198 content-length. The problem had been corrected in the 2.4 branch, but never
3199 merged into trunk.
3200
Georg Brandle78fbcc2008-07-05 10:13:36 +00003201- Issue #2663: add filtering capability to shutil.copytree().

3207- Issue #1746: Correct handling of zipfile archive comments (previously
3208 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00003209 Zip files with archives by setting the 'comment' attribute of a ZipFile.

3606 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003607 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003608
3609 This is controlled by the configure argument ``--with-universal-archs``:
3610
3611 - ``--with-universal-archs=all``: install 4-way universal
3612
3613 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3614
3615 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3616
3617 This option should be used in combination with ``--enable-universalsdk=``.
3618
3619 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 +00003669- Issue #1631171: Re-implement the 'warnings' module in C (the
3670 original Python code has been kept as backup). This will allow for
3671 using the 'warning's machinery in such places as the parser where
3672 use of pure Python code is not possible. Both the ``showarning()``
3673 and ``formatwarning()`` gain an optional 'line' argument which is
3674 not called by default for backwards-compatibility reasons. Setting
3675 ``warnings.showwarning()`` to an implementation that lacks support
3676 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003701- The getpass module has been improved on Unix. It now uses /dev/tty
3702 by default and uses stderr instead of stdout. A GetPassWarning is
3703 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003718- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003719 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003739- Issue #2550: The approach used by client/server code for obtaining
3740 ports to listen on in network-oriented tests has been refined in an
3741 effort to facilitate running multiple instances of the entire
3742 regression test suite in parallel without issue.
3743 test_support.bind_port() has been fixed such that it will always
3744 return a unique port -- which wasn't always the case with the
3745 previous implementation, especially if socket options had been set
3746 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3747 new implementation of bind_port() will actually raise an exception
3748 if it is passed an AF_INET/SOCK_STREAM socket with either the
3749 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3750 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3751 the socket it's been passed. This currently only applies to
3752 Windows. This option prevents any other sockets from binding to the
3753 host/port we've bound to, thus removing the possibility of the
3754 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3755 when a second SOCK_STREAM socket binds and accepts to a host/port
3756 that's already been bound by another socket. The optional preferred
3757 port parameter to bind_port() has been removed. Under no
3758 circumstances should tests be hard coding ports!
3759
3760 test_support.find_unused_port() has also been introduced, which will
3761 pass a temporary socket object to bind_port() in order to obtain an
3762 unused port. The temporary socket object is then closed and
3763 deleted, and the port is returned. This method should only be used
3764 for obtaining an unused port in order to pass to an external program
3765 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3766 a parameter to a server-oriented class that doesn't give you direct
3767 access to the underlying socket used.
3768
3769 Finally, test_support.HOST has been introduced, which should be used
3770 for the host argument of any relevant socket calls (i.e. bind and
3771 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003772

4045Core and builtins
4046-----------------
4047
Fred Drakea8ee94b2008-03-01 02:45:07 +00004048- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004049 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004050
Georg Brandlad61bc82008-02-23 15:11:18 +00004051- Issue #2067: file.__exit__() now calls subclasses' close() method.
4052
4053- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004054
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004055- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004056 issue 215555 for a discussion.
4057
Eric Smitha73fbe72008-02-23 03:09:44 +00004058- Added the future_builtins module, which contains hex() and oct().
4059 These are the PEP 3127 version of these functions, designed to be
4060 compatible with the hex() and oct() builtins from Python 3.0. They
4061 differ slightly in their output formats from the existing, unchanged
4062 Python 2.6 builtins. The expected usage of the future_builtins
4063 module is:
4064 from future_builtins import hex, oct
4065
Eric Smith7ef40bf2008-02-20 23:34:22 +00004066- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4067 exponents for exponents with absolute value < 100. Follows C99
4068 standard. This is a change on Windows, which would use 3 digits.
4069 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4070 so that any alterations it does to the resulting string will be
4071 available in stringlib/formatter.h (for float.__format__).
4072
Eric Smith5a3c1352008-02-19 13:21:56 +00004073- Implemented PEP 3101, Advanced String Formatting. This adds a new
4074 builtin format(); a format() method for str and unicode; a
4075 __format__() method to object, str, unicode, int, long, float, and
4076 datetime; the class string.Formatter; and the C API
4077 PyObject_Format().
4078
Georg Brandl3ee81df2008-05-17 18:14:43 +00004079- Fixed several potential crashes, all caused by specially crafted
4080 __del__ methods exploiting objects in temporarily inconsistent
4081 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004082
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004083- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004084 prevent a possible crash: an Abstract Base Class would try to access
4085 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004086
Georg Brandl3ee81df2008-05-17 18:14:43 +00004087- Fixed repr() and str() of complex numbers with infinity or nan as
4088 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004089
Georg Brandl3ee81df2008-05-17 18:14:43 +00004090- Clear all free lists during a gc.collect() of the highest generation
4091 in order to allow pymalloc to free more arenas. Python may give back
4092 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004093
Georg Brandl3ee81df2008-05-17 18:14:43 +00004094- Issue #2045: Fix an infinite recursion triggered when printing a
4095 subclass of collections.defaultdict, if its default_factory is set
4096 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004097
Christian Heimesf75dbef2008-02-08 00:11:31 +00004098- Fixed a minor memory leak in dictobject.c. The content of the free
4099 list was not freed on interpreter shutdown.
4100
Georg Brandl21e99f42010-03-07 15:23:59 +00004101- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004102 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004103
Georg Brandl3ee81df2008-05-17 18:14:43 +00004104- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4105 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004106 to compact the internal free lists of pre-allocted ints and floats.
4107
Georg Brandl3ee81df2008-05-17 18:14:43 +00004108- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4109 calls. Python expected the return type int but the fork familie
4110 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004111
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4113 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004114
Georg Brandl3ee81df2008-05-17 18:14:43 +00004115- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4116 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004117
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4119 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004120
Georg Brandl3ee81df2008-05-17 18:14:43 +00004121- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4122 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004123
Georg Brandl3ee81df2008-05-17 18:14:43 +00004124- Patch #1473257: generator objects gain a gi_code attribute. This is
4125 the same object as the func_code attribute of the function that
4126 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004127
Georg Brandl3ee81df2008-05-17 18:14:43 +00004128- Issue #1920: "while 0" statements were completely removed by the
4129 compiler, even in the presence of an "else" clause, which is
4130 supposed to be run when the condition is false. Now the compiler
4131 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004132
Guido van Rossumeead05f2008-01-24 18:21:02 +00004133- A few crashers fixed: weakref_in_del.py (issue #1377858);
4134 loosing_dict_ref.py (issue #1303614, test67.py);
4135 borrowed_ref_[34].py (not in tracker).
4136
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004137- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004138 suppressed while an extension is loaded by calling SetErrorMode in
4139 dynload_win.c. The error is still reported properly.
4140
Georg Brandl3ee81df2008-05-17 18:14:43 +00004141- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004142 several extension methods and modules do not work without unicode
4143 support.
4144
Georg Brandl26543b12008-01-21 18:36:51 +00004145- Issue #1882: when compiling code from a string, encoding cookies in the
4146 second line of code were not always recognized correctly.
4147
Georg Brandl14404b62008-01-19 19:27:05 +00004148- Issue #1679: "0x" was taken as a valid integer literal.
4149
Georg Brandl6caad7d2008-01-26 14:19:22 +00004150- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004151 added.
4152
Christian Heimesc94e2b52008-01-14 04:13:37 +00004153- sys.float_info / PyFloat_GetInfo: The floating point information
4154 object was converted from a dict to a specialized structseq object.
4155
Georg Brandl3ee81df2008-05-17 18:14:43 +00004156- Patch #1816: Added sys.flags structseq. It exposes the status of
4157 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Objects/structseq.c: Implemented new structseq representation. The
4160 patch makes structseqs (e.g. the return value of os.stat) more
4161 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004162
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163- Patch #1700288: added a type attribute cache that caches method
4164 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004165
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004166- Bug #1776: __import__() no longer accepts filenames on any platform.
4167 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004168
Georg Brandlaed6c662008-01-07 17:25:53 +00004169- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4170
Georg Brandl3ee81df2008-05-17 18:14:43 +00004171- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4172 envvar and sys.dont_write_bytecode attribute. All these can be set
4173 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004174
Georg Brandl3ee81df2008-05-17 18:14:43 +00004175- Improve some exception messages when Windows fails to load an
4176 extension module. Now we get for example '%1 is not a valid Win32
4177 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004178
Georg Brandl3ee81df2008-05-17 18:14:43 +00004179- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004181- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4182 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004183
Christian Heimes0a8143f2007-12-18 23:22:54 +00004184- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185 and INF. float("nan"), float("inf") and float("-inf") now work on
4186 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004187
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188- Compiler now generates simpler and faster code for dictionary
4189 literals. The oparg for BUILD_MAP now indicates an estimated
4190 dictionary size. There is a new opcode, STORE_MAP, for adding
4191 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004198- Issue #1538: Avoid copying string in split/rsplit if the split char
4199 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004200
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004201- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004202 SystemError.
4203
Nick Coghlanef01d822007-12-03 12:55:17 +00004204- PEP 366: Allow explicit relative imports when executing modules
4205 inside packages with the -m switch via a new module level
4206 __package__ attribute.
4207
Georg Brandl3ee81df2008-05-17 18:14:43 +00004208- Issue #1402: Fix a crash on exit, when another thread is still
4209 running, and if the deallocation of its frames somehow calls the
4210 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004211

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004215 attribute of an empty cell object.
4216
Georg Brandl3ee81df2008-05-17 18:14:43 +00004217- Issue #1460: The utf-7 incremental decoder did not accept truncated
4218 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004219
Georg Brandl3ee81df2008-05-17 18:14:43 +00004220- Patch #1739468: Directories and zipfiles containing a __main__.py
4221 file can now be directly executed by passing their name to the
4222 interpreter. The directory/zipfile is automatically inserted as the
4223 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004224
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225- Issue #1265: Fix a problem with sys.settrace, if the tracing
4226 function uses a generator expression when at the same time the
4227 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004228
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004229- sets and frozensets now have an isdisjoint() method.
4230
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004231- optimize the performance of builtin.sum().
4232
Neal Norwitz44f326e2007-10-05 05:29:17 +00004233- Fix warnings found by the new version of the Coverity checker.
4234
Georg Brandl21e99f42010-03-07 15:23:59 +00004235- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4237 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004238
Georg Brandl3ee81df2008-05-17 18:14:43 +00004239- Issue #1686386: Tuple's tp_repr did not take into account the
4240 possibility of having a self-referential tuple, which is possible
4241 from C code. Nor did object's tp_str consider that a type's tp_str
4242 could do something that could lead to an inifinite recursion.
4243 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4244 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004245
Georg Brandl3ee81df2008-05-17 18:14:43 +00004246- Issue #1164: It was possible to trigger deadlock when using the
4247 'print' statement to write to a file since the GIL was not released
4248 as needed. Now PyObject_Print() does the right thing along with
4249 various tp_print implementations of the built-in types and those in
4250 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004251
Georg Brandl3ee81df2008-05-17 18:14:43 +00004252- Issue #1147: Exceptions were directly allowing string exceptions in
4253 their throw() method even though string exceptions no longer
4254 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004255

Brett Cannon1e534b52007-09-07 04:18:30 +00004259- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004260 PyObject_Call() never calling back out to Python code to trigger
4261 recursion depth updates/checks. Required the creation of a static
4262 RuntimeError instance in case normalizing an exception put the
4263 recursion check value past its limit. Fixes crashers
4264 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004279- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004280 __*__ attributes. (Some already existed, e.g., __doc__ and
4281 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004282
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004283- Add -3 option to the interpreter to warn about features that are

4288
Collin Winter62903052007-05-18 23:11:24 +00004289- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004290 "except E as target:". This is to provide forwards compatibility
4291 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004292
Brett Cannon229cee22007-05-05 01:34:02 +00004293- Deprecate BaseException.message as per PEP 352.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004299 setting a plain string, ie don't expand to single letter identifiers.
4300
Raymond Hettinger13936692007-04-11 18:40:58 +00004301- Request #1191699: Slices can now be pickled.
4302

4311
Guido van Rossum143b5642007-03-23 04:58:42 +00004312- Bug #1683368: The object.__init__() and object.__new__() methods are
4313 now stricter in rejecting excess arguments. The only time when
4314 either allows excess arguments is when it is not overridden and the
4315 other one is. For backwards compatibility, when both are
4316 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004317 warning later). Also, type.__init__() insists on the same signature
4318 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004319
Georg Brandl3ee81df2008-05-17 18:14:43 +00004320- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4321 object to complex using its __complex__() method before falling back
4322 to the __float__() method. Therefore, the functions in the cmath
4323 module now can operate on objects that define a __complex__()
4324 method.

4327 __slots__. The old and the new class are still required to have the
4328 same slot names.

4341
Georg Brandl7b9c5552007-03-12 14:30:05 +00004342- Bug #1678647: write a newline after printing an exception in any
4343 case, even when converting the value to a string failed.
4344
Georg Brandl871f1bc2007-03-12 13:17:36 +00004345- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004346 its argument, if it exists. If not, it will work like before. This
4347 allows customizing the output of dir() in the presence of a
4348 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004349
Collin Winter276887b2007-03-12 16:11:39 +00004350- Patch #922167: Python no longer segfaults when faced with infinitely
4351 self-recursive reload() calls (as reported by bug #742342).
4352

4357 parthensized forms. This means complex(repr(x)) now works instead of
4358 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004359
Georg Brandlaa2321b2007-03-07 00:40:28 +00004360- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004361 makes the filenames the warning module prints much more sensible
4362 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004363

Georg Brandl0fca97a2007-03-05 22:28:08 +00004375- Patch #1674228: when assigning a slice (old-style), check for the
4376 sq_ass_slice instead of the sq_slice slot.
4377
Georg Brandl3ee81df2008-05-17 18:14:43 +00004378- When printing an unraisable error, don't print exceptions. before
4379 the name. This duplicates the behavior whening normally printing
4380 exceptions.

5003
Georg Brandl3ee81df2008-05-17 18:14:43 +00005004- unittest now verifies more of its assumptions. In particular,

5006 accepted in TestSuite.addTest(). This should cause no
5007 incompatibility since it never made sense with ordinary subclasses
5008 -- the failure just occurred later, with a more cumbersome
5009 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005290- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5291 with RFC 3207 and forgets any knowledge obtained from the server not
5292 obtained from the TLS negotiation itself. Patch contributed by Bill
5293 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005294
Georg Brandl3ee81df2008-05-17 18:14:43 +00005295- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005296 that the SMTP.starttls() caller no longer needs to call ehlo()
5297 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005298 does not claim to support starttls. Adds the
5299 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5380 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5381 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005398 time so that opening a database previously created with the DB_DUP
5399 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5400 opens. Specifically: dictionary assignment to a DB object will
5401 replace all values for a given key when the database allows
5402 duplicate values. DB users should use DB.put(k, v) when they want
5403 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005404

5410 characters with ASCII value less than 32. Also, it correctly quotes
5411 dots only if they occur on a single line, as opposed to the previous
5412 behavior of quoting dots if they are the second character of any
5413 line.

5737
Georg Brandl3ee81df2008-05-17 18:14:43 +00005738- Unified naming convention for free lists and their limits. All free
5739 lists in Object/ are named ``free_list``, the counter ``numfree``
5740 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5741 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005742
Georg Brandl3ee81df2008-05-17 18:14:43 +00005743- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5744 to ``PyTuple_SetItem``, it can be used to populate a brand new
5745 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005746
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005747- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005748
Georg Brandl3ee81df2008-05-17 18:14:43 +00005749- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5750 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5751 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005752
5753- Patch #1720595: add T_BOOL to the range of structmember types.
5754
5755- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5756 ``PyFloat_GetInfo()`` to the float API.
5757
Georg Brandl3ee81df2008-05-17 18:14:43 +00005758- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5759 of w# format code incorrectly truncated the length to an int, even
5760 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5761 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005762
Georg Brandl3ee81df2008-05-17 18:14:43 +00005763- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5764 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005765
Georg Brandl3ee81df2008-05-17 18:14:43 +00005766- PEP 3123: Provide forward compatibility with Python 3.0, while
5767 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5768 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005769
Georg Brandl3ee81df2008-05-17 18:14:43 +00005770- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5771 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005772
5773- Patch #1733960: Allow T_LONGLONG to accept ints.
5774
5775- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5776
Christian Heimes000a0742008-01-03 22:16:32 +00005777- Added a new API function ``PyImport_ImportModuleNoBlock``.
5778
Georg Brandl6caad7d2008-01-26 14:19:22 +00005779- Bug #1637022: Prefix AST symbols with _Py_.
5780
5781- Fix some leftovers from the conversion from int to Py_ssize_t
5782 (relevant to strings and sequences of more than 2**31 items).
5783
5784- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5785 outside of pystate.c and should not be necessary.
5786
Georg Brandl3ee81df2008-05-17 18:14:43 +00005787- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5788 absolute imports. In earlier versions they might have used relative
5789 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005790
Georg Brandl3ee81df2008-05-17 18:14:43 +00005791- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5792 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005793
Georg Brandl3ee81df2008-05-17 18:14:43 +00005794- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5795 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005801- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5802 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5803 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5804 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005805
Georg Brandl3ee81df2008-05-17 18:14:43 +00005806- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5807 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005819- Removed the macfs module. It had been deprecated since Python 2.5.
5820 This lead to the deprecation of macostools.touched() as it relied
5821 solely on macfs and was a no-op under OS X.
