14
Mark Dickinsona8d26682010-05-04 16:18:25 +000015- Issue #1533: fix inconsistency in range function argument
16 processing: any non-float non-integer argument is now converted to
17 an integer (if possible) using its __int__ method. Previously, only
18 small arguments were treated this way; larger arguments (those whose
19 __int__ was outside the range of a C long) would produce a TypeError.
20
Nick Coghlanc5e44852010-04-28 14:51:08 +000021- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when
22 searching for the module file to be executed with the -m command
23 line option
24
Brett Cannon19949692010-04-25 22:33:36 +000025- Issue #7319: When -Q is used, do not silence DeprecationWarning.
26
Antoine Pitrou18e63fb2010-04-21 22:53:29 +000027- Issue #7332: Remove the 16KB stack-based buffer in
28 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
29 benefit compared to the dynamic memory allocation fallback. Patch by
30 Charles-François Natali.
31
Benjamin Peterson821a8ea2010-04-16 22:35:38 +000032- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
33 passed to bytearray.

43 parent and any children created using ``os.fork`` on MacOS X 10.6.
44
Victor Stinner926fd4e2010-05-05 12:40:49 +000045- Issue #8313: traceback.format_exception_only() encodes unicode message to
46 ASCII with backslashreplace error handler if str(value) failed
47
Mark Dickinson4f96f5f2010-05-04 14:25:50 +000048- Issue #8567: Fix precedence of signals in Decimal module: when a
49 Decimal operation raises multiple signals and more than one of those
50 signals is trapped, the specification determines the order in which
51 the signals should be handled. In many cases this order wasn't
52 being followed, leading to the wrong Python exception being raised.
53
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +000054- Issue #7865: The close() method of :mod:`io` objects should not swallow
55 exceptions raised by the implicit flush(). Also ensure that calling
56 close() several times is supported. Patch by Pascal Chambon.
57
Vinay Sajip27a13702010-05-03 15:11:53 +000058- Issue #8576: logging updated to remove usage of find_unused_port().

64 webbrowser.get("safari").
65
Tarek Ziadéa5cd1822010-04-30 12:15:12 +000066- Issue #8577: distutils.sysconfig.get_python_inc() now makes a difference
67 between the build dir and the source dir when looking for "python.h" or
68 "Include".
69
Lars Gustäbel5c4c4612010-04-29 15:23:38 +000070- Issue #8464: tarfile no longer creates files with execute permissions set
71 when mode="w|" is used.

74 of the Linux kernel. Patch by Yaniv Aknin.
75
Senthil Kumaraned9204342010-04-28 17:20:43 +000076- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
77 It should correctly return an empty response now.
78
Nick Coghlandfb45df2010-04-28 14:29:06 +000079- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
80 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
Nick Coghlan54677da2010-04-28 14:34:30 +000081 location of the raised exception. Based on initial patch by Lennart
82 Regebro.
Nick Coghlandfb45df2010-04-28 14:29:06 +000083

96 where the method could block indefinitely if called just before the
97 event loop started running. This also fixes the occasional freezes
98 witnessed in test_httpservers.
99
Antoine Pitroufc69af12010-04-24 20:04:58 +0000100- Issue #5103: SSL handshake would ignore the socket timeout and block
101 indefinitely if the other end didn't respond.
102
Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000103- The do_handshake() method of SSL objects now adjusts the blocking mode of
104 the SSL structure if necessary (as other methods already do).
105
Georg Brandl4341e542010-04-24 09:08:10 +0000106- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
107
Antoine Pitroub558f172010-04-23 23:25:45 +0000108- Issue #5238: Calling makefile() on an SSL object would prevent the
109 underlying socket from being closed until all objects get truely destroyed.

113
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +0000114- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of

116 and keywords.
117
Antoine Pitroua5c4b552010-04-22 23:33:02 +0000118- Issue #8108: Fix the unwrap() method of SSL objects when the socket has

121 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
122
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000123- Issue #8484: Load all ciphers and digest algorithms when initializing
124 the _ssl extension, such that verification of some SSL certificates
125 doesn't fail because of an "unknown algorithm".
126
Victor Stinnera92e81b2010-04-20 22:28:31 +0000127- Issue #8437: Fix test_gdb failures, patch written by Dave Malcolm
128
Giampaolo Rodolà607f7c02010-04-19 21:46:28 +0000129- Issue #4814: timeout parameter is now applied also for connections resulting
130 from PORT/EPRT commands.
131

203Core and Builtins
204-----------------
205
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000206- Issue #7301: Add environment variable $PYTHONWARNINGS.
207
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000208- Issue #8329: Don't return the same lists from select.select when no fds are
209 changed.
210
Mark Dickinson82791672010-04-06 16:47:55 +0000211- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
212 on 64-bit machines. The shift count for either left or right shift is
213 permitted to be up to sys.maxsize.
214
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000215- Ensure that tokenization of identifiers is not affected by locale.
216
Tarek Ziadé00002952010-04-03 08:37:59 +0000217- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

220
Eric Smithd44b2fc2010-04-02 12:30:56 +0000221- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
222 is called with a non-empty format string. This is an effort to
223 future-proof user code. If a derived class does not currently
224 implement __format__ but later adds its own __format__, it would
225 most likely break user code that had supplied a format string. This
226 will be changed to a DeprecationWaring in Python 3.3 and it will be
227 an error in Python 3.4.
228
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000229- Issue #8268: Old-style classes (not just instances) now support weak
230 references.

Georg Brandlba83f822010-03-14 09:50:54 +0000243 (SIGINT). If an error occurs while importing the site module, the error is
244 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000245 module.
246
Collin Winter001a3952010-03-18 21:54:01 +0000247- Code objects now support weak references.

253
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000254- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
255 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
256 and `ssl.OPENSSL_VERSION_NUMBER`.
257
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000258- Issue #8310: Allow dis to examine new style classes.
259
Mark Dickinson8a950712010-04-03 15:47:46 +0000260- Issue #8257: The Decimal construct now accepts a float instance
261 directly, converting that float to a Decimal of equal value:
262
263 >>> Decimal(1.1)
264 Decimal('1.100000000000000088817841970012523233890533447265625')
265
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000266- collections.Counter() now supports a subtract() method.
267
Raymond Hettingera551f312010-04-04 18:34:45 +0000268- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000269 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000270
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000271- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000272 old-style comparison functions to new-style key-functions.
273
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000274- Issue #8294: The Fraction constructor now accepts Decimal and float
275 instances directly.
276
Mark Dickinsone096e822010-04-02 10:17:07 +0000277- Issue #7279: Comparisons involving a Decimal signaling NaN now
278 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000279 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
280 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000281
Mark Dickinson99d80962010-04-02 08:53:22 +0000282- Issue #2531: Comparison operations between floats and Decimal
283 instances now return a result based on the numeric values of the
284 operands; previously they returned an arbitrary result based on
285 the relative ordering of id(float) and id(Decimal).
286
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000287- Issue #8233: When run as a script, py_compile.py optionally takes a single
288 argument `-` which tells it to read files to compile from stdin. Each line
289 is read on demand and the named file is compiled immediately. (Original
290 patch by Piotr Ożarowski).
291
292- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
293 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000294
Florent Xicluna58b65662010-03-30 16:29:03 +0000295- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
296 form feed (0x0C) are now considered linebreaks, as specified in Unicode
297 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000298 http://www.unicode.org/reports/tr14/
299
Mark Dickinson9588d992010-03-27 11:14:37 +0000300- Comparisons using one of <, <=, >, >= between a complex instance and
301 a Fractions instance now raise TypeError instead of returning
302 True/False. This makes Fraction <=> complex comparisons consistent with
303 int <=> complex, float <=> complex, and complex <=> complex comparisons.
304
Michael Foorde6410c52010-03-29 20:04:23 +0000305- Addition of ``WeakSet`` to the ``weakref`` module.

Georg Brandlba83f822010-03-14 09:50:54 +0000407- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
408 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
409 argument's __int__ method to convert to an integer before packing. It also
410 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
411 was inconsistent: __int__ was used for some integer codes but not for others,
412 and the set of integer codes for which it was used differed between native
413 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000711 file position when calling `truncate()`. It would previously change the file
712 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000713 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

718 class used to represent files stored inside an archive. The new
719 implementation is significantly faster and can be wrapped in a
720 ``io.BufferedReader`` object for more speedups. It also solves an issue
721 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Benjamin Petersona43f34c2010-01-25 03:31:13 +0000731
Georg Brandlba83f822010-03-14 09:50:54 +0000732- Issue #7748: Since unicode values are supported for some metadata options in
733 Distutils, the DistributionMetadata get_* methods will now return an utf-8
734 encoded string for them. This ensures that the upload and register commands
735 send the correct values to PyPI without any error.

820 These functions and methods now raise TypeError instead. The majority of the
821 effects of this change are in the extension modules, but some core functions
822 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
823 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00001006- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1007 decimal string that's guaranteed to round back to x under correct rounding
1008 (with round-half-to-even rounding mode). Previously it gave a string based on
1009 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1010 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1011 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001012
Georg Brandlba83f822010-03-14 09:50:54 +00001013- Issue #7117: On almost all platforms: float-to-string and string-to-float
1014 conversions within Python are now correctly rounded. Places these conversions
1015 occur include: str for floats and complex numbers; the float and complex
1016 constructors; old-style and new-style numeric formatting; serialization and
1017 deserialization of floats and complex numbers using marshal, pickle and json;
1018 parsing of float and imaginary literals in Python code; Decimal-to-float
1019 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001020
Georg Brandlba83f822010-03-14 09:50:54 +00001021 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1022 providing correctly-rounded strtod and dtoa C functions. This code is
1023 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1024 the C compiler. There may be a small number of platforms on which correct
1025 operation of this code cannot be guaranteed, so the code is not used: notably,
1026 this applies to platforms where the C double format is not IEEE 754 binary64,
1027 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1028 and Python's configure script is unable to determine how to change the FPU
1029 precision. On these platforms conversions use the platform strtod and dtoa,
1030 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001031
Georg Brandlba83f822010-03-14 09:50:54 +00001032- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1033 uses the correctly-rounded string <-> float conversions described above (when
1034 available), and so produces correctly rounded results that will display nicely
1035 under the float repr. There are two related small changes: (1) round now
1036 accepts any class with an ``__index__()`` method for its second argument (but
1037 no longer accepts floats for the second argument), and (2) an excessively
1038 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1039 raises an exception.

1389
Georg Brandlba83f822010-03-14 09:50:54 +00001390- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1391 file objects with closefd=False. The file descriptor is still kept open but
1392 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00001416- On windows, ``os.chdir()`` given unicode was not working if
1417 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1418 this code path is really executed because I cannot move to such directory on
1419 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001421- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1422 element is temporarily replaced with an equivalent frozenset. But the
1423 eventual KeyError would always report the empty ``frozenset()`` as the missing

1445 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1446 step. This avoids problems with counting UTF-8 bytes that ignores the effect

Walter Dörwald726ba8e2009-05-06 14:32:35 +00001449- Issue #3739: The unicode-internal encoder now reports the number of characters

2821
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002822- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2823 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2824 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2825 ``printf`` function, whereas PyString_FromFormat has an independent
2826 implementation and uses "%zd" on all platforms for size_t values.
2827 This makes a difference on win64, where ``printf`` needs "%Id" to display
2828 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002830- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2834 object; previously an int would be returned for small values. the __long__

2846
Vinay Sajip35e3b032008-09-01 14:33:59 +00002847- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002848 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2849 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2850 when given a tuple of classes as second argument, were looking up
2851 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2852 type object.

2925 DeprecationWarning related to warnings.warn_explicit().
2926
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002927- The deprecation warnings for the old camelCase threading API were removed.
2928

2932
Christian Heimes1cc69632008-08-22 20:10:27 +00002933- Fixed two format strings in the _collections module.
2934

2949
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002950- Issue #2975: When compiling several extension modules with Visual Studio 2008
2951 from the same python interpreter, some environment variables would grow
2952 without limit.
2953
Benjamin Peterson37346b22008-08-23 20:27:43 +00002954- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2955 exploitation of poor argument checking.
2956
Gerhard Häringef2276b2008-09-12 13:54:06 +00002957- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

2960 remaining ones have "pysqlite_" prefix.
2961
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002962- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002991What's New in Python 2.6 beta 3?
2992================================
2993
Barry Warsaw07a4a382008-08-21 01:15:08 +00002994*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002995
2996Core and Builtins
2997-----------------
2998
Guido van Rossumf8402962008-08-20 15:01:50 +00002999- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3000 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3001 extensions do not automatically benefit from the class attribute
3002 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3003 to their tp_flags field if they care. This is a backwards
3004 compatibility feature; in 3.0, all types will use the cache by
3005 default.
3006
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003007- Keyword arguments can now follow starred arguments. (``f(a, *args,
3008 keyword=23)`` is now valid syntax.)
3009
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003010- ctypes function pointers that are COM methods have a boolean True
3011 value again.
3012
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003013- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3014 by denying s# to parse objects that have a releasebuffer procedure,
3015 and introducing s*.
3016
Georg Brandl1e13ea92008-08-11 09:07:59 +00003017- Issue #3537: Fix an assertion failure when an empty but presized dict
3018 object was stored in the freelist.
3019
Mark Dickinsonb6467572008-08-04 21:30:09 +00003020- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3021 ValueError consistently across platforms.
3022
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003023- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3024 (64bit Unix, for example), unichr() would truncate its argument and return
3025 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3026
Neal Norwitze7d8be82008-07-31 17:17:14 +00003027- Apply security patches from Apple.
3028
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003029- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3030 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3031
Antoine Pitrou92f82162008-07-25 22:22:08 +00003032- Issue #1819: function calls with several named parameters are now on
3033 average 35% faster (as measured by pybench).
3034
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003035- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3036 the python debugger steps into a class statement: the free variables (local
3037 variables defined in an outer scope) would be deleted from the outer scope.
3038
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003039- Issue #2620: Overflow checking when allocating or reallocating memory
3040 was not always being done properly in some python types and extension
3041 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3042 all been updated to perform better checks and places in the code that
3043 would previously leak memory on the error path when such an allocation
3044 failed have been fixed.
3045
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003046Library

3050
Benjamin Petersone977ad42008-08-20 01:42:01 +00003051- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3052 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3053
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003054- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3055 version reported by these tools does not necessarily follow the python
3056 version numbering scheme, so the module is less strict when parsing it.
3057
Nick Coghlanf70385a2008-08-18 12:42:46 +00003058- Issue #2235: Added Py3k warnings for types which will become unhashable
3059 under the stricter __hash__ inheritance rules in 3.0. Several types
3060 which did not meet the rules for hash invariants and were already
3061 unhashable in 3.0 have now been explicitly flagged as unhashable in
3062 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3063 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3064
Brett Cannon88f801d2008-08-18 00:46:22 +00003065- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3066 imported into the module but exposed as part of the module's API.
3067

3073
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003074- Issue #3575: Incremental decoder's decode function now takes bytearray
3075 by using 's*' instead of 't#'.
3076
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003077- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003078 fails unicode conversion on 2nd parameter. (windows only)
3079
Facundo Batista94f243a2008-08-17 03:38:39 +00003080- Issue 2464. urllib2 now supports a malformation in the URL received
3081 in a redirect.
3082
Brett Cannonabe423e2008-08-16 21:47:07 +00003083- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003084 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003085
Facundo Batistaeb90b782008-08-16 14:44:07 +00003086- Issue #2776: fixed small issue when handling an URL with double slash
3087 after a 302 response in the case of not going through a proxy.
3088
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003089- Issue #2676: in the email package, content-type parsing was hanging on
3090 pathological input because of quadratic or exponential behaviour of a
3091 regular expression.
3092
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003093- Issue #3476: binary buffered reading through the new "io" library is now
3094 thread-safe.
3095
Brett Cannonbf3157b2008-08-14 05:00:03 +00003096- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3097 since mimetools itself is deprecated. Because modules are cached, all
3098 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3099
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003100- Issue #3134: shutil referenced undefined WindowsError symbol.
3101
Robert Schuppenies14646332008-08-10 11:01:53 +00003102- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3103 menu entries were not deleted.
3104
Brett Cannon83e81842008-08-09 23:30:55 +00003105- Copied the implementation of reduce() to _functools.reduce() to have a
3106 version that did not raise a DeprecationWarning under -3.
3107
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003108- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3109 a MemoryError rather than silently stop the iteration.
3110
Guido van Rossum59ce9012008-08-09 14:55:34 +00003111- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3112 to _sre.compile() will now be rejected. This should not affect anybody
3113 since the re.compile() function never generates invalid re-bytecode.
3114
Skip Montanaroa032bf42008-08-08 22:52:51 +00003115- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3116 upon first access it can be automatically initialized from the csv file if
3117 it wasn't initialized during instantiation.
3118
Brett Cannon3aa2a492008-08-06 22:28:09 +00003119- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3120 the reload() built-in has been removed.
3121
Brett Cannon7e30b672008-08-04 21:52:25 +00003122- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003123 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3131 raised an AttributeError.
3132
Benjamin Peterson01a24322008-07-28 23:35:27 +00003133- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003134 asking for a specific length. This problem only affected files opened
3135 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003136

3159
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003160- Issue #3394: zipfile.writestr sets external attributes when passed a
3161 file name rather than a ZipInfo instance, so files are extracted with
3162 mode 0600 rather than 000 under Unix.
3163
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003164- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3165 argument in python 2.5, this broke code that subclassed Popen to include its
3166 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3180 coverage of the lookup process for special methods. The disclaimers
3181 regarding lack of coverage of new-style classes have also been
3182 removed, since the coverage is now fairly reasonable.

3191-----------------
3192
Georg Brandl3e483f62008-07-16 22:57:41 +00003193- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3194 its methods now allow for items objects that can be converted to
3195 an integer using operator.index().
3196
Mark Dickinson64b7e502008-07-16 09:40:03 +00003197- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3198 produced a ValueError instead of giving the correct float.
3199
Eric Smitha5fa5a22008-07-16 00:11:49 +00003200- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3201 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3202
Mark Dickinson7103aa42008-07-15 19:08:33 +00003203- Issue #3008: the float type has a new instance method 'float.hex'
3204 and a new class method 'float.fromhex' to convert floating-point
3205 numbers to and from hexadecimal strings, respectively.
3206
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003207- Issue #2235: __hash__ is once again inherited by default. To allow
3208 collections.Hashable to remain meaningful in the presence of the
3209 default hash implementation (object.__hash__), it is now possible
3210 to explicit block inheritance of hash by setting __hash__=None at
3211 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3212 level.
3213
Nick Coghlanb028f502008-07-13 14:52:36 +00003214- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3215 the parent module cannot be found while performing an absolute import.
3216 This means that an incorrectly defined __package__ attribute will
3217 now only prevent relative imports in that module rather than causing

Georg Brandl5cc774e2008-06-11 20:28:06 +00003691 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003692
3693 This is controlled by the configure argument ``--with-universal-archs``:

3740 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003753- Issue #1631171: Re-implement the 'warnings' module in C (the
3754 original Python code has been kept as backup). This will allow for
3755 using the 'warning's machinery in such places as the parser where
3756 use of pure Python code is not possible. Both the ``showarning()``
3757 and ``formatwarning()`` gain an optional 'line' argument which is
3758 not called by default for backwards-compatibility reasons. Setting
3759 ``warnings.showwarning()`` to an implementation that lacks support
3760 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003823- Issue #2550: The approach used by client/server code for obtaining
3824 ports to listen on in network-oriented tests has been refined in an
3825 effort to facilitate running multiple instances of the entire
3826 regression test suite in parallel without issue.
3827 test_support.bind_port() has been fixed such that it will always
3828 return a unique port -- which wasn't always the case with the
3829 previous implementation, especially if socket options had been set
3830 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3831 new implementation of bind_port() will actually raise an exception
3832 if it is passed an AF_INET/SOCK_STREAM socket with either the
3833 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3834 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3835 the socket it's been passed. This currently only applies to
3836 Windows. This option prevents any other sockets from binding to the
3837 host/port we've bound to, thus removing the possibility of the
3838 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3839 when a second SOCK_STREAM socket binds and accepts to a host/port
3840 that's already been bound by another socket. The optional preferred
3841 port parameter to bind_port() has been removed. Under no
3842 circumstances should tests be hard coding ports!
3843
3844 test_support.find_unused_port() has also been introduced, which will
3845 pass a temporary socket object to bind_port() in order to obtain an
3846 unused port. The temporary socket object is then closed and
3847 deleted, and the port is returned. This method should only be used
3848 for obtaining an unused port in order to pass to an external program
3849 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3850 a parameter to a server-oriented class that doesn't give you direct
3851 access to the underlying socket used.
3852
3853 Finally, test_support.HOST has been introduced, which should be used
3854 for the host argument of any relevant socket calls (i.e. bind and
3855 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003856
3857 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003858 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003859 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3860 test_asynchat and test_socket_ssl.
3861
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862 It is now possible for multiple instances of the regression test
3863 suite to run in parallel without issue.

4131
Fred Drakea8ee94b2008-03-01 02:45:07 +00004132- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004133 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004135- Issue #2067: file.__exit__() now calls subclasses' close() method.
4136
4137- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004138
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004139- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004140 issue 215555 for a discussion.
4141
Eric Smitha73fbe72008-02-23 03:09:44 +00004142- Added the future_builtins module, which contains hex() and oct().
4143 These are the PEP 3127 version of these functions, designed to be
4144 compatible with the hex() and oct() builtins from Python 3.0. They
4145 differ slightly in their output formats from the existing, unchanged
4146 Python 2.6 builtins. The expected usage of the future_builtins
4147 module is:
4148 from future_builtins import hex, oct
4149
Eric Smith7ef40bf2008-02-20 23:34:22 +00004150- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4151 exponents for exponents with absolute value < 100. Follows C99
4152 standard. This is a change on Windows, which would use 3 digits.
4153 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4154 so that any alterations it does to the resulting string will be
4155 available in stringlib/formatter.h (for float.__format__).
4156
Eric Smith5a3c1352008-02-19 13:21:56 +00004157- Implemented PEP 3101, Advanced String Formatting. This adds a new
4158 builtin format(); a format() method for str and unicode; a
4159 __format__() method to object, str, unicode, int, long, float, and
4160 datetime; the class string.Formatter; and the C API
4161 PyObject_Format().
4162
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163- Fixed several potential crashes, all caused by specially crafted
4164 __del__ methods exploiting objects in temporarily inconsistent
4165 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004166
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004167- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004168 prevent a possible crash: an Abstract Base Class would try to access
4169 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004170

Georg Brandl3ee81df2008-05-17 18:14:43 +00004174- Clear all free lists during a gc.collect() of the highest generation
4175 in order to allow pymalloc to free more arenas. Python may give back
4176 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004177
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Issue #2045: Fix an infinite recursion triggered when printing a
4179 subclass of collections.defaultdict, if its default_factory is set
4180 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004181
Christian Heimesf75dbef2008-02-08 00:11:31 +00004182- Fixed a minor memory leak in dictobject.c. The content of the free
4183 list was not freed on interpreter shutdown.
4184
Georg Brandl21e99f42010-03-07 15:23:59 +00004185- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004186 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004187
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4189 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004190 to compact the internal free lists of pre-allocted ints and floats.
4191
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4193 calls. Python expected the return type int but the fork familie
4194 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004195
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4197 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004198
Georg Brandl3ee81df2008-05-17 18:14:43 +00004199- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4200 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004201

Georg Brandl3ee81df2008-05-17 18:14:43 +00004205- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4206 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004207
Georg Brandl3ee81df2008-05-17 18:14:43 +00004208- Patch #1473257: generator objects gain a gi_code attribute. This is
4209 the same object as the func_code attribute of the function that
4210 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004211
Georg Brandl3ee81df2008-05-17 18:14:43 +00004212- Issue #1920: "while 0" statements were completely removed by the
4213 compiler, even in the presence of an "else" clause, which is
4214 supposed to be run when the condition is false. Now the compiler
4215 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004216
Guido van Rossumeead05f2008-01-24 18:21:02 +00004217- A few crashers fixed: weakref_in_del.py (issue #1377858);
4218 loosing_dict_ref.py (issue #1303614, test67.py);
4219 borrowed_ref_[34].py (not in tracker).
4220
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004221- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004222 suppressed while an extension is loaded by calling SetErrorMode in
4223 dynload_win.c. The error is still reported properly.
4224
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004226 several extension methods and modules do not work without unicode
4227 support.
4228
Georg Brandl26543b12008-01-21 18:36:51 +00004229- Issue #1882: when compiling code from a string, encoding cookies in the
4230 second line of code were not always recognized correctly.
4231
Georg Brandl14404b62008-01-19 19:27:05 +00004232- Issue #1679: "0x" was taken as a valid integer literal.
4233
Georg Brandl6caad7d2008-01-26 14:19:22 +00004234- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004235 added.
4236
Christian Heimesc94e2b52008-01-14 04:13:37 +00004237- sys.float_info / PyFloat_GetInfo: The floating point information
4238 object was converted from a dict to a specialized structseq object.
4239
Georg Brandl3ee81df2008-05-17 18:14:43 +00004240- Patch #1816: Added sys.flags structseq. It exposes the status of
4241 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004242
Georg Brandl3ee81df2008-05-17 18:14:43 +00004243- Objects/structseq.c: Implemented new structseq representation. The
4244 patch makes structseqs (e.g. the return value of os.stat) more
4245 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004246
Georg Brandl3ee81df2008-05-17 18:14:43 +00004247- Patch #1700288: added a type attribute cache that caches method

4256 envvar and sys.dont_write_bytecode attribute. All these can be set
4257 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004258
Georg Brandl3ee81df2008-05-17 18:14:43 +00004259- Improve some exception messages when Windows fails to load an
4260 extension module. Now we get for example '%1 is not a valid Win32
4261 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004262

Christian Heimes0a8143f2007-12-18 23:22:54 +00004268- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004269 and INF. float("nan"), float("inf") and float("-inf") now work on
4270 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004271
Georg Brandl3ee81df2008-05-17 18:14:43 +00004272- Compiler now generates simpler and faster code for dictionary
4273 literals. The oparg for BUILD_MAP now indicates an estimated
4274 dictionary size. There is a new opcode, STORE_MAP, for adding
4275 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004276
Georg Brandl3ee81df2008-05-17 18:14:43 +00004277- Issue #1638: %zd configure test fails on Linux.

4318
Georg Brandl21e99f42010-03-07 15:23:59 +00004319- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004320 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4321 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004322
Georg Brandl3ee81df2008-05-17 18:14:43 +00004323- Issue #1686386: Tuple's tp_repr did not take into account the
4324 possibility of having a self-referential tuple, which is possible
4325 from C code. Nor did object's tp_str consider that a type's tp_str
4326 could do something that could lead to an inifinite recursion.
4327 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4328 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004329
Georg Brandl3ee81df2008-05-17 18:14:43 +00004330- Issue #1164: It was possible to trigger deadlock when using the
4331 'print' statement to write to a file since the GIL was not released
4332 as needed. Now PyObject_Print() does the right thing along with
4333 various tp_print implementations of the built-in types and those in
4334 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004344 PyObject_Call() never calling back out to Python code to trigger
4345 recursion depth updates/checks. Required the creation of a static
4346 RuntimeError instance in case normalizing an exception put the
4347 recursion check value past its limit. Fixes crashers
4348 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004364 __*__ attributes. (Some already existed, e.g., __doc__ and
4365 __name__.)

4371 calls.
4372
Collin Winter62903052007-05-18 23:11:24 +00004373- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004374 "except E as target:". This is to provide forwards compatibility
4375 with Python 3.0.

4395
Guido van Rossum143b5642007-03-23 04:58:42 +00004396- Bug #1683368: The object.__init__() and object.__new__() methods are
4397 now stricter in rejecting excess arguments. The only time when
4398 either allows excess arguments is when it is not overridden and the
4399 other one is. For backwards compatibility, when both are
4400 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004401 warning later). Also, type.__init__() insists on the same signature
4402 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004404- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4405 object to complex using its __complex__() method before falling back
4406 to the __float__() method. Therefore, the functions in the cmath
4407 module now can operate on objects that define a __complex__()
4408 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004426- Bug #1678647: write a newline after printing an exception in any
4427 case, even when converting the value to a string failed.
4428
Georg Brandl871f1bc2007-03-12 13:17:36 +00004429- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004430 its argument, if it exists. If not, it will work like before. This
4431 allows customizing the output of dir() in the presence of a
4432 __getattr__().

4442 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004443
Georg Brandlaa2321b2007-03-07 00:40:28 +00004444- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004445 makes the filenames the warning module prints much more sensible
4446 when a PYTHONSTARTUP file is used.

4461
Georg Brandl3ee81df2008-05-17 18:14:43 +00004462- When printing an unraisable error, don't print exceptions. before

5093 exception.

5375 with RFC 3207 and forgets any knowledge obtained from the server not
5376 obtained from the TLS negotiation itself. Patch contributed by Bill
5377 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005378
Georg Brandl3ee81df2008-05-17 18:14:43 +00005379- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005380 that the SMTP.starttls() caller no longer needs to call ehlo()
5381 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005382 does not claim to support starttls. Adds the
5383 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00005467

Georg Brandl3ee81df2008-05-17 18:14:43 +00005482 time so that opening a database previously created with the DB_DUP
5483 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5484 opens. Specifically: dictionary assignment to a DB object will
5485 replace all values for a given key when the database allows
5486 duplicate values. DB users should use DB.put(k, v) when they want
5487 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005488

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005766- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005767 periodic threadstate and signal checking in tight loops. By
5768 default, this option is turned-off. It should only be enabled in
5769 debugged, performance critical applications.

5825 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005826
Georg Brandl3ee81df2008-05-17 18:14:43 +00005827- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5828 to ``PyTuple_SetItem``, it can be used to populate a brand new
5829 frozenset; but it does not steal a reference to the added item.

5841
Georg Brandl3ee81df2008-05-17 18:14:43 +00005842- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5843 of w# format code incorrectly truncated the length to an int, even
5844 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5845 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005846

Georg Brandl3ee81df2008-05-17 18:14:43 +00005871- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5872 absolute imports. In earlier versions they might have used relative
5873 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005874
Georg Brandl3ee81df2008-05-17 18:14:43 +00005875- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5876 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005877
Georg Brandl3ee81df2008-05-17 18:14:43 +00005878- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
