Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00007What's New in Python 2.7 beta 1?
8================================
9
10*Release date: XXXX-XX-XX*
11
12Core and Builtins
13-----------------
14
Philip Jenveyaebbaeb2010-04-06 23:24:45 +000015- Issue #7301: Add environment variable $PYTHONWARNINGS.
16
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000017- Issue #8329: Don't return the same lists from select.select when no fds are
18 changed.
19
Mark Dickinson82791672010-04-06 16:47:55 +000020- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
21 on 64-bit machines. The shift count for either left or right shift is
22 permitted to be up to sys.maxsize.
23
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000024- Ensure that tokenization of identifiers is not affected by locale.
25
Tarek Ziadé00002952010-04-03 08:37:59 +000026- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
27
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000028- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
29
Eric Smithd44b2fc2010-04-02 12:30:56 +000030- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
31 is called with a non-empty format string. This is an effort to
32 future-proof user code. If a derived class does not currently
33 implement __format__ but later adds its own __format__, it would
34 most likely break user code that had supplied a format string. This
35 will be changed to a DeprecationWaring in Python 3.3 and it will be
36 an error in Python 3.4.
37
Antoine Pitroua57df2c2010-03-31 21:32:15 +000038- Issue #8268: Old-style classes (not just instances) now support weak
39 references.
40
Victor Stinner6cbf90f2010-03-25 00:21:53 +000041- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
42 optimizations are disabled when --with-pydebug is used.
43
Victor Stinnerc7790ed2010-03-22 12:36:28 +000044- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000045
Benjamin Peterson96545892010-03-21 20:21:00 +000046- Issue #6474: Make error message from passing an inadequate number of keyword
47 arguments to a function correct.
48
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000049- Issue #8164: Don't allow lambda functions to have a docstring.

Georg Brandlba83f822010-03-14 09:50:54 +000052 (SIGINT). If an error occurs while importing the site module, the error is
53 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000054 module.
55
Collin Winter001a3952010-03-18 21:54:01 +000056- Code objects now support weak references.

Martin v. Löwis1b287c72010-04-08 09:47:40 +000063- Issue #8344: Fix test_ttk bug on FreeBSD.
64
Antoine Pitrouf9de5342010-04-05 21:35:07 +000065- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
66 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
67 and `ssl.OPENSSL_VERSION_NUMBER`.
68
Benjamin Peterson76a23c12010-04-04 23:23:22 +000069- Issue #8310: Allow dis to examine new style classes.
70
Mark Dickinson8a950712010-04-03 15:47:46 +000071- Issue #8257: The Decimal construct now accepts a float instance
72 directly, converting that float to a Decimal of equal value:
73
74 >>> Decimal(1.1)
75 Decimal('1.100000000000000088817841970012523233890533447265625')
76
Raymond Hettinger34c35b22010-04-03 10:22:00 +000077- collections.Counter() now supports a subtract() method.
78
Raymond Hettingera551f312010-04-04 18:34:45 +000079- the functools module now has a total_ordering() class decorator
80 to simplify the specifying rich comparisons.
81
Raymond Hettingerbb006cf2010-04-04 21:45:01 +000082- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +000083 old-style comparison functions to new-style key-functions.
84
Mark Dickinson7c63eee2010-04-02 22:27:36 +000085- Issue #8294: The Fraction constructor now accepts Decimal and float
86 instances directly.
87
Mark Dickinsone096e822010-04-02 10:17:07 +000088- Issue #7279: Comparisons involving a Decimal signaling NaN now
89 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000090 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
91 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000092
Mark Dickinson99d80962010-04-02 08:53:22 +000093- Issue #2531: Comparison operations between floats and Decimal
94 instances now return a result based on the numeric values of the
95 operands; previously they returned an arbitrary result based on
96 the relative ordering of id(float) and id(Decimal).
97
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000098- Issue #8233: When run as a script, py_compile.py optionally takes a single
99 argument `-` which tells it to read files to compile from stdin. Each line
100 is read on demand and the named file is compiled immediately. (Original
101 patch by Piotr Ożarowski).
102
103- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
104 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000105
Florent Xicluna58b65662010-03-30 16:29:03 +0000106- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
107 form feed (0x0C) are now considered linebreaks, as specified in Unicode
108 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000109 http://www.unicode.org/reports/tr14/
110
Mark Dickinson9588d992010-03-27 11:14:37 +0000111- Comparisons using one of <, <=, >, >= between a complex instance and
112 a Fractions instance now raise TypeError instead of returning
113 True/False. This makes Fraction <=> complex comparisons consistent with
114 int <=> complex, float <=> complex, and complex <=> complex comparisons.
115
Michael Foorde6410c52010-03-29 20:04:23 +0000116- Addition of ``WeakSet`` to the ``weakref`` module.
117
Vinay Sajipb0623d62010-03-24 14:31:21 +0000118- logging: Added LOG_FTP to SysLogHandler and updated documentation.
119

121 running from the build directory (POSIX only).
122
Florent Xiclunae1f4c922010-03-22 22:45:50 +0000123- Issue #7667: Fix doctest failures with non-ASCII paths.
124
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000125- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
126 didn't support chflags() (for example ZFS under FreeBSD). The error is
127 now silenced.
128
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000129- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
130 deprecated.
131
R. David Murrayc9d1a782010-03-22 15:55:09 +0000132- Issue #7860: platform.uname now reports the correct 'machine' type
133 when Python is running in WOW64 mode on 64 bit Windows.
134
Vinay Sajip804899b2010-03-22 15:29:01 +0000135- logging: Added getChild utility method to Logger and added isEnabledFor
136 method to LoggerAdapter.
137
Vinay Sajip31e928e2010-03-22 13:02:28 +0000138- Issue #8201: logging: Handle situation of non-ASCII and Unicode
139 logger names existing at the same time, causing a Unicode error
140 when configuration code attempted to sort the existing loggers.
141
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000142- Issue #8200: logging: Handle errors when multiprocessing is not
143 fully loaded when logging occurs.
144
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000145- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
146 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
147 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000148
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000149- Issue #8179: Fix macpath.realpath() on a non-existing path.

Matthias Klose358e7ff2010-03-15 13:42:23 +0000162- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
163 the locale.
164
Georg Brandlba83f822010-03-14 09:50:54 +0000165- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000166 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000167 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000168
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000169- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000170 for ``TimedRotatingFileHandler`` by using the modification time of an
171 existing log file to compute the next rollover time. If the log file does
172 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000173
Georg Brandlba83f822010-03-14 09:50:54 +0000174- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

181
Georg Brandlba83f822010-03-14 09:50:54 +0000182- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
183 a base64 transfer-encoded payload *after* decoding it; it no longer does.
184 This is a behavior change, so email's minor version number is now bumped, to
185 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000186
Larry Hastings3b958e32010-04-02 11:18:17 +0000187- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is

Martin v. Löwis16ea5482010-04-07 11:01:46 +0000201- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
202
Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000203- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
204
Jesus Cea6557aac2010-03-22 14:22:26 +0000205- Issue #8156: bsddb module updated to version 4.8.4.

Matthias Klose817acef2010-03-15 00:02:36 +0000209- Issue #8142: Update libffi to the 3.0.9 release.
210
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000211- Issue #8300: When passing a non-integer argument to struct.pack with any
212 integer format code, struct.pack first attempts to convert the non-integer
213 using its __index__ method. If that method is non-existent or raises
214 TypeError it goes on to try the __int__ method, as described below.
215
Georg Brandlba83f822010-03-14 09:50:54 +0000216- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
217 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
218 argument's __int__ method to convert to an integer before packing. It also
219 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
220 was inconsistent: __int__ was used for some integer codes but not for others,
221 and the set of integer codes for which it was used differed between native
222 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000223
Brian Curtin19479fa2010-04-02 21:51:37 +0000224- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a

259
Larry Hastings402b73f2010-03-25 00:54:54 +0000260- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported

518 class used to represent files stored inside an archive. The new
519 implementation is significantly faster and can be wrapped in a

617
Mark Dickinson1b34d252010-01-01 17:27:30 +0000618- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000619 DeprecationWarning when passed a float argument where an integer was expected.
620 These functions and methods now raise TypeError instead. The majority of the
621 effects of this change are in the extension modules, but some core functions
622 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
623 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000788- Issue #3382: 'F' formatting for float and complex now convert the result to
789 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
790 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000791
Georg Brandlba83f822010-03-14 09:50:54 +0000792- Remove switch from "%f" formatting to "%g" formatting for floats larger than
793 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000794
Georg Brandlba83f822010-03-14 09:50:54 +0000795- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
796 1e-100 used to raise OverflowError, but now gives the requested 120
797 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000798
Georg Brandlba83f822010-03-14 09:50:54 +0000799- Add Py3k warnings for parameter names in parentheses.

Georg Brandlba83f822010-03-14 09:50:54 +0000803- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
804 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000805
Georg Brandlba83f822010-03-14 09:50:54 +0000806- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
807 decimal string that's guaranteed to round back to x under correct rounding
808 (with round-half-to-even rounding mode). Previously it gave a string based on
809 rounding x to 17 decimal digits. repr(x) for a complex number behaves
810 similarly. On platforms where the correctly-rounded strtod and dtoa code is
811 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000812
Georg Brandlba83f822010-03-14 09:50:54 +0000813- Issue #7117: On almost all platforms: float-to-string and string-to-float
814 conversions within Python are now correctly rounded. Places these conversions
815 occur include: str for floats and complex numbers; the float and complex
816 constructors; old-style and new-style numeric formatting; serialization and
817 deserialization of floats and complex numbers using marshal, pickle and json;
818 parsing of float and imaginary literals in Python code; Decimal-to-float
819 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000820
Georg Brandlba83f822010-03-14 09:50:54 +0000821 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
822 providing correctly-rounded strtod and dtoa C functions. This code is
823 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
824 the C compiler. There may be a small number of platforms on which correct
825 operation of this code cannot be guaranteed, so the code is not used: notably,
826 this applies to platforms where the C double format is not IEEE 754 binary64,
827 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
828 and Python's configure script is unable to determine how to change the FPU
829 precision. On these platforms conversions use the platform strtod and dtoa,
830 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000831
Georg Brandlba83f822010-03-14 09:50:54 +0000832- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
833 uses the correctly-rounded string <-> float conversions described above (when
834 available), and so produces correctly rounded results that will display nicely
835 under the float repr. There are two related small changes: (1) round now
836 accepts any class with an ``__index__()`` method for its second argument (but
837 no longer accepts floats for the second argument), and (2) an excessively
838 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
839 raises an exception.

842
Georg Brandlba83f822010-03-14 09:50:54 +0000843- Fix several issues with ``compile()``. The input can now contain Windows and
844 Mac newlines and is no longer required to end in a newline.

Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000874- Issue #1571184: The Unicode database contains properties for more characters.
875 The tables for code points representing numeric values, white spaces or line
876 breaks are now generated from the official Unicode Character Database files,
877 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +0000986- Issue #5920: For ``float.__format__()``, change the behavior with the empty
987 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
988 but with at least one decimal point and with a default precision
989 of 12. Previously, the behavior the same but with a default precision of 6.
990 This more closely matches ``str()``, and reduces surprises when adding
991 alignment flags to the empty presentation type. This also affects the new
992 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00001132- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1133 existing .py counterpart, override the co_filename attributes of all code

Walter Dörwalded960ac2009-05-03 22:36:33 +00001244- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1245 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

1253 allocator will be automatically disabled when running under Valgrind. This
1254 gives improved memory leak detection when running under Valgrind, while taking
1255 advantage of pymalloc at other times.

2624 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

Antoine Pitrou0668c622008-08-26 22:42:08 +00002648 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2649 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2650 when given a tuple of classes as second argument, were looking up
2651 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2652 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002791What's New in Python 2.6 beta 3?
2792================================
2793
Barry Warsaw07a4a382008-08-21 01:15:08 +00002794*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002795
2796Core and Builtins
2797-----------------
2798
Guido van Rossumf8402962008-08-20 15:01:50 +00002799- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2800 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2801 extensions do not automatically benefit from the class attribute
2802 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2803 to their tp_flags field if they care. This is a backwards
2804 compatibility feature; in 3.0, all types will use the cache by
2805 default.
2806
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002807- Keyword arguments can now follow starred arguments. (``f(a, *args,
2808 keyword=23)`` is now valid syntax.)
2809
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002810- ctypes function pointers that are COM methods have a boolean True
2811 value again.
2812
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002813- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2814 by denying s# to parse objects that have a releasebuffer procedure,
2815 and introducing s*.
2816
Georg Brandl1e13ea92008-08-11 09:07:59 +00002817- Issue #3537: Fix an assertion failure when an empty but presized dict
2818 object was stored in the freelist.
2819
Mark Dickinsonb6467572008-08-04 21:30:09 +00002820- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2821 ValueError consistently across platforms.
2822
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002823- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2824 (64bit Unix, for example), unichr() would truncate its argument and return
2825 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2826
Neal Norwitze7d8be82008-07-31 17:17:14 +00002827- Apply security patches from Apple.
2828
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002829- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2830 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2831
Antoine Pitrou92f82162008-07-25 22:22:08 +00002832- Issue #1819: function calls with several named parameters are now on
2833 average 35% faster (as measured by pybench).
2834
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002835- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2836 the python debugger steps into a class statement: the free variables (local
2837 variables defined in an outer scope) would be deleted from the outer scope.
2838
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002839- Issue #2620: Overflow checking when allocating or reallocating memory
2840 was not always being done properly in some python types and extension
2841 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2842 all been updated to perform better checks and places in the code that
2843 would previously leak memory on the error path when such an allocation
2844 failed have been fixed.

2848
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002849- Issue #3612: Added some missing basic types in ctypes.wintypes.
2850
Benjamin Petersone977ad42008-08-20 01:42:01 +00002851- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2852 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2853
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002854- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2855 version reported by these tools does not necessarily follow the python
2856 version numbering scheme, so the module is less strict when parsing it.
2857
Nick Coghlanf70385a2008-08-18 12:42:46 +00002858- Issue #2235: Added Py3k warnings for types which will become unhashable
2859 under the stricter __hash__ inheritance rules in 3.0. Several types
2860 which did not meet the rules for hash invariants and were already
2861 unhashable in 3.0 have now been explicitly flagged as unhashable in
2862 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2863 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2864
Brett Cannon88f801d2008-08-18 00:46:22 +00002865- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2866 imported into the module but exposed as part of the module's API.
2867
Brett Cannon7b96f072008-08-18 00:41:11 +00002868- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2869
Brett Cannon46225e72008-08-18 00:36:52 +00002870- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2871
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002872- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2873
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002874- Issue #3575: Incremental decoder's decode function now takes bytearray
2875 by using 's*' instead of 't#'.
2876
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002877- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002878 fails unicode conversion on 2nd parameter. (windows only)
2879
Facundo Batista94f243a2008-08-17 03:38:39 +00002880- Issue 2464. urllib2 now supports a malformation in the URL received
2881 in a redirect.
2882
Brett Cannonabe423e2008-08-16 21:47:07 +00002883- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002884 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002885
Facundo Batistaeb90b782008-08-16 14:44:07 +00002886- Issue #2776: fixed small issue when handling an URL with double slash
2887 after a 302 response in the case of not going through a proxy.
2888
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002889- Issue #2676: in the email package, content-type parsing was hanging on
2890 pathological input because of quadratic or exponential behaviour of a
2891 regular expression.
2892
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002893- Issue #3476: binary buffered reading through the new "io" library is now
2894 thread-safe.
2895
Brett Cannonbf3157b2008-08-14 05:00:03 +00002896- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2897 since mimetools itself is deprecated. Because modules are cached, all
2898 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2899
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002900- Issue #3134: shutil referenced undefined WindowsError symbol.
2901
Robert Schuppenies14646332008-08-10 11:01:53 +00002902- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2903 menu entries were not deleted.
2904
Brett Cannon83e81842008-08-09 23:30:55 +00002905- Copied the implementation of reduce() to _functools.reduce() to have a
2906 version that did not raise a DeprecationWarning under -3.
2907
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002908- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2909 a MemoryError rather than silently stop the iteration.
2910
Guido van Rossum59ce9012008-08-09 14:55:34 +00002911- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2912 to _sre.compile() will now be rejected. This should not affect anybody
2913 since the re.compile() function never generates invalid re-bytecode.
2914
Skip Montanaroa032bf42008-08-08 22:52:51 +00002915- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2916 upon first access it can be automatically initialized from the csv file if
2917 it wasn't initialized during instantiation.
2918
Brett Cannon3aa2a492008-08-06 22:28:09 +00002919- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2920 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00002934 asking for a specific length. This problem only affected files opened
2935 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002936

2961 file name rather than a ZipInfo instance, so files are extracted with
2962 mode 0600 rather than 000 under Unix.
2963
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002964- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2991-----------------
2992
Georg Brandl3e483f62008-07-16 22:57:41 +00002993- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2994 its methods now allow for items objects that can be converted to
2995 an integer using operator.index().
2996
Mark Dickinson64b7e502008-07-16 09:40:03 +00002997- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2998 produced a ValueError instead of giving the correct float.
2999
Eric Smitha5fa5a22008-07-16 00:11:49 +00003000- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3001 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3002
Mark Dickinson7103aa42008-07-15 19:08:33 +00003003- Issue #3008: the float type has a new instance method 'float.hex'
3004 and a new class method 'float.fromhex' to convert floating-point
3005 numbers to and from hexadecimal strings, respectively.
3006
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003007- Issue #2235: __hash__ is once again inherited by default. To allow
3008 collections.Hashable to remain meaningful in the presence of the
3009 default hash implementation (object.__hash__), it is now possible
3010 to explicit block inheritance of hash by setting __hash__=None at
3011 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3012 level.
3013
Nick Coghlanb028f502008-07-13 14:52:36 +00003014- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3015 the parent module cannot be found while performing an absolute import.
3016 This means that an incorrectly defined __package__ attribute will
3017 now only prevent relative imports in that module rather than causing
3018 all imports from that module to fail.
3019
Nick Coghlan14ff9942008-07-08 14:21:42 +00003020- Issue #2517: Allow unicode messages in Exceptions again by correctly

3029 threading.local: the first member set by a thread could be saved in
3030 another thread's dictionary.
3031
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003032- Issue #3004: Minor change to slice.indices(): the start and stop
3033 arguments are now treated identically, making the behaviour easier
3034 to describe and understand. For example, slice(None, -10,
3035 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3036 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3037 10, -1).
3038
Georg Brandl278fc502008-07-19 12:46:12 +00003039- Issue #3219: Calling a function with repeated keyword arguments,
3040 f(a=2, a=23), would not cause a syntax error. This was a regression
3041 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003042
Georg Brandl278fc502008-07-19 12:46:12 +00003043- Issue #2862: Make int and float freelist management consistent with
3044 other freelists. Changes their CompactFreeList apis into

3051 api functions without holding the GIL, which could lead to a fatal
3052 error when they failed.
3053
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003054- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003079- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3080 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003081 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003082 content-length. The problem had been corrected in the 2.4 branch, but never
3083 merged into trunk.
3084
Georg Brandle78fbcc2008-07-05 10:13:36 +00003085- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003098- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3099 handling is now the same as that of other special attributes like __name__).
3100
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003101- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003489- On MacOS X it is now possible to install the framework in 64-bit
3490 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003491 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003492
3493 This is controlled by the configure argument ``--with-universal-archs``:
3494
3495 - ``--with-universal-archs=all``: install 4-way universal
3496
3497 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3498
3499 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3500
3501 This option should be used in combination with ``--enable-universalsdk=``.
3502
3503 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3508
Georg Brandl74a1dea2008-05-28 11:21:39 +00003509- Add ``PyType_Modified()`` as a public API to clear the type cache.
3510
3511- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003512
3513- The PyString functions have been renamed to PyBytes. A batch of
3514 defines were added so that the linker still sees the original
3515 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003553- Issue #1631171: Re-implement the 'warnings' module in C (the
3554 original Python code has been kept as backup). This will allow for
3555 using the 'warning's machinery in such places as the parser where
3556 use of pure Python code is not possible. Both the ``showarning()``
3557 and ``formatwarning()`` gain an optional 'line' argument which is
3558 not called by default for backwards-compatibility reasons. Setting
3559 ``warnings.showwarning()`` to an implementation that lacks support
3560 for the ``line`` argument will raise a DeprecationWarning.

3584
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003585- The getpass module has been improved on Unix. It now uses /dev/tty
3586 by default and uses stderr instead of stdout. A GetPassWarning is
3587 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003602- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003603 extension modules between 32 and 64 bit platforms. See the distutls

3616 so the controlled environment will more closely mirror the typical
3617 script environment. This supports setup.py scripts that refer to
3618 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003623- Issue #2550: The approach used by client/server code for obtaining
3624 ports to listen on in network-oriented tests has been refined in an
3625 effort to facilitate running multiple instances of the entire
3626 regression test suite in parallel without issue.
3627 test_support.bind_port() has been fixed such that it will always
3628 return a unique port -- which wasn't always the case with the
3629 previous implementation, especially if socket options had been set
3630 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3631 new implementation of bind_port() will actually raise an exception
3632 if it is passed an AF_INET/SOCK_STREAM socket with either the
3633 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3634 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3635 the socket it's been passed. This currently only applies to
3636 Windows. This option prevents any other sockets from binding to the
3637 host/port we've bound to, thus removing the possibility of the
3638 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3639 when a second SOCK_STREAM socket binds and accepts to a host/port
3640 that's already been bound by another socket. The optional preferred
3641 port parameter to bind_port() has been removed. Under no
3642 circumstances should tests be hard coding ports!
3643
3644 test_support.find_unused_port() has also been introduced, which will
3645 pass a temporary socket object to bind_port() in order to obtain an
3646 unused port. The temporary socket object is then closed and
3647 deleted, and the port is returned. This method should only be used
3648 for obtaining an unused port in order to pass to an external program
3649 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3650 a parameter to a server-oriented class that doesn't give you direct
3651 access to the underlying socket used.
3652
3653 Finally, test_support.HOST has been introduced, which should be used
3654 for the host argument of any relevant socket calls (i.e. bind and
3655 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003656
3657 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003658 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003659 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3660 test_asynchat and test_socket_ssl.
3661
Georg Brandl3ee81df2008-05-17 18:14:43 +00003662 It is now possible for multiple instances of the regression test
3663 suite to run in parallel without issue.

3930-----------------
3931
Fred Drakea8ee94b2008-03-01 02:45:07 +00003932- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003933 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003938
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003939- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003940 issue 215555 for a discussion.
3941
Eric Smitha73fbe72008-02-23 03:09:44 +00003942- Added the future_builtins module, which contains hex() and oct().
3943 These are the PEP 3127 version of these functions, designed to be
3944 compatible with the hex() and oct() builtins from Python 3.0. They
3945 differ slightly in their output formats from the existing, unchanged
3946 Python 2.6 builtins. The expected usage of the future_builtins
3947 module is:
3948 from future_builtins import hex, oct
3949
Eric Smith7ef40bf2008-02-20 23:34:22 +00003950- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3951 exponents for exponents with absolute value < 100. Follows C99
3952 standard. This is a change on Windows, which would use 3 digits.
3953 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3954 so that any alterations it does to the resulting string will be
3955 available in stringlib/formatter.h (for float.__format__).
3956
Eric Smith5a3c1352008-02-19 13:21:56 +00003957- Implemented PEP 3101, Advanced String Formatting. This adds a new
3958 builtin format(); a format() method for str and unicode; a
3959 __format__() method to object, str, unicode, int, long, float, and
3960 datetime; the class string.Formatter; and the C API
3961 PyObject_Format().
3962
Georg Brandl3ee81df2008-05-17 18:14:43 +00003963- Fixed several potential crashes, all caused by specially crafted
3964 __del__ methods exploiting objects in temporarily inconsistent
3965 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003966
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003967- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003968 prevent a possible crash: an Abstract Base Class would try to access
3969 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003974- Clear all free lists during a gc.collect() of the highest generation
3975 in order to allow pymalloc to free more arenas. Python may give back
3976 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003977
Georg Brandl3ee81df2008-05-17 18:14:43 +00003978- Issue #2045: Fix an infinite recursion triggered when printing a
3979 subclass of collections.defaultdict, if its default_factory is set
3980 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003981
Christian Heimesf75dbef2008-02-08 00:11:31 +00003982- Fixed a minor memory leak in dictobject.c. The content of the free
3983 list was not freed on interpreter shutdown.
3984
Georg Brandl21e99f42010-03-07 15:23:59 +00003985- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003986 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003987

3989 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003990 to compact the internal free lists of pre-allocted ints and floats.
3991
Georg Brandl3ee81df2008-05-17 18:14:43 +00003992- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3993 calls. Python expected the return type int but the fork familie
3994 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003995

4006 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004007
Georg Brandl3ee81df2008-05-17 18:14:43 +00004008- Patch #1473257: generator objects gain a gi_code attribute. This is
4009 the same object as the func_code attribute of the function that
4010 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004011
Georg Brandl3ee81df2008-05-17 18:14:43 +00004012- Issue #1920: "while 0" statements were completely removed by the
4013 compiler, even in the presence of an "else" clause, which is
4014 supposed to be run when the condition is false. Now the compiler
4015 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004016
Guido van Rossumeead05f2008-01-24 18:21:02 +00004017- A few crashers fixed: weakref_in_del.py (issue #1377858);
4018 loosing_dict_ref.py (issue #1303614, test67.py);
4019 borrowed_ref_[34].py (not in tracker).
4020
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004021- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004022 suppressed while an extension is loaded by calling SetErrorMode in
4023 dynload_win.c. The error is still reported properly.
4024
Georg Brandl3ee81df2008-05-17 18:14:43 +00004025- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004026 several extension methods and modules do not work without unicode
4027 support.
4028
Georg Brandl26543b12008-01-21 18:36:51 +00004029- Issue #1882: when compiling code from a string, encoding cookies in the
4030 second line of code were not always recognized correctly.
4031
Georg Brandl14404b62008-01-19 19:27:05 +00004032- Issue #1679: "0x" was taken as a valid integer literal.
4033
Georg Brandl6caad7d2008-01-26 14:19:22 +00004034- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004035 added.
4036
Christian Heimesc94e2b52008-01-14 04:13:37 +00004037- sys.float_info / PyFloat_GetInfo: The floating point information
4038 object was converted from a dict to a specialized structseq object.
4039
Georg Brandl3ee81df2008-05-17 18:14:43 +00004040- Patch #1816: Added sys.flags structseq. It exposes the status of
4041 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004042
Georg Brandl3ee81df2008-05-17 18:14:43 +00004043- Objects/structseq.c: Implemented new structseq representation. The
4044 patch makes structseqs (e.g. the return value of os.stat) more
4045 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004046
Georg Brandl3ee81df2008-05-17 18:14:43 +00004047- Patch #1700288: added a type attribute cache that caches method
4048 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004049
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004050- Bug #1776: __import__() no longer accepts filenames on any platform.
4051 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004052
Georg Brandlaed6c662008-01-07 17:25:53 +00004053- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4054
Georg Brandl3ee81df2008-05-17 18:14:43 +00004055- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4056 envvar and sys.dont_write_bytecode attribute. All these can be set
4057 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004058
Georg Brandl3ee81df2008-05-17 18:14:43 +00004059- Improve some exception messages when Windows fails to load an
4060 extension module. Now we get for example '%1 is not a valid Win32
4061 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004062
Georg Brandl3ee81df2008-05-17 18:14:43 +00004063- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004065- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4066 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004067
Christian Heimes0a8143f2007-12-18 23:22:54 +00004068- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004069 and INF. float("nan"), float("inf") and float("-inf") now work on
4070 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004071
Georg Brandl3ee81df2008-05-17 18:14:43 +00004072- Compiler now generates simpler and faster code for dictionary
4073 literals. The oparg for BUILD_MAP now indicates an estimated
4074 dictionary size. There is a new opcode, STORE_MAP, for adding
4075 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004076
Georg Brandl3ee81df2008-05-17 18:14:43 +00004077- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004079- Issue #1620: New property decorator syntax was modifying the
4080 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004081
Georg Brandl3ee81df2008-05-17 18:14:43 +00004082- Issue #1538: Avoid copying string in split/rsplit if the split char
4083 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004084
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004085- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004086 SystemError.
4087
Nick Coghlanef01d822007-12-03 12:55:17 +00004088- PEP 366: Allow explicit relative imports when executing modules
4089 inside packages with the -m switch via a new module level
4090 __package__ attribute.
4091
Georg Brandl3ee81df2008-05-17 18:14:43 +00004092- Issue #1402: Fix a crash on exit, when another thread is still
4093 running, and if the deallocation of its frames somehow calls the
4094 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004095

4100
Georg Brandl3ee81df2008-05-17 18:14:43 +00004101- Issue #1460: The utf-7 incremental decoder did not accept truncated
4102 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004103
Georg Brandl3ee81df2008-05-17 18:14:43 +00004104- Patch #1739468: Directories and zipfiles containing a __main__.py
4105 file can now be directly executed by passing their name to the
4106 interpreter. The directory/zipfile is automatically inserted as the
4107 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004108
Georg Brandl3ee81df2008-05-17 18:14:43 +00004109- Issue #1265: Fix a problem with sys.settrace, if the tracing
4110 function uses a generator expression when at the same time the
4111 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004112
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004113- sets and frozensets now have an isdisjoint() method.
4114
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004115- optimize the performance of builtin.sum().
4116
Neal Norwitz44f326e2007-10-05 05:29:17 +00004117- Fix warnings found by the new version of the Coverity checker.
4118
Georg Brandl21e99f42010-03-07 15:23:59 +00004119- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004120 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4121 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004122
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123- Issue #1686386: Tuple's tp_repr did not take into account the
4124 possibility of having a self-referential tuple, which is possible
4125 from C code. Nor did object's tp_str consider that a type's tp_str
4126 could do something that could lead to an inifinite recursion.
4127 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4128 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004129
Georg Brandl3ee81df2008-05-17 18:14:43 +00004130- Issue #1164: It was possible to trigger deadlock when using the
4131 'print' statement to write to a file since the GIL was not released
4132 as needed. Now PyObject_Print() does the right thing along with
4133 various tp_print implementations of the built-in types and those in
4134 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004135
Georg Brandl3ee81df2008-05-17 18:14:43 +00004136- Issue #1147: Exceptions were directly allowing string exceptions in
4137 their throw() method even though string exceptions no longer
4138 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004139
Georg Brandl3ee81df2008-05-17 18:14:43 +00004140- Issue #1096: Prevent a segfault from getting the repr of a very
4141 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004142
Brett Cannon1e534b52007-09-07 04:18:30 +00004143- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004144 PyObject_Call() never calling back out to Python code to trigger
4145 recursion depth updates/checks. Required the creation of a static
4146 RuntimeError instance in case normalizing an exception put the
4147 recursion check value past its limit. Fixes crashers
4148 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004149
Georg Brandl3ee81df2008-05-17 18:14:43 +00004150- Patch #1031213: Decode source line in SyntaxErrors back to its

4154 with %G.
4155
Georg Brandl3ee81df2008-05-17 18:14:43 +00004156- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00004163- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004164 __*__ attributes. (Some already existed, e.g., __doc__ and
4165 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004166
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004167- Add -3 option to the interpreter to warn about features that are
4168 deprecated and will be changed/removed in Python 3.0.
4169
Georg Brandl2134e752007-05-21 20:34:16 +00004170- Patch #1686487: you can now pass any mapping after '**' in function
4171 calls.
4172
Collin Winter62903052007-05-18 23:11:24 +00004173- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004174 "except E as target:". This is to provide forwards compatibility
4175 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004176
Brett Cannon229cee22007-05-05 01:34:02 +00004177- Deprecate BaseException.message as per PEP 352.
4178
Georg Brandl3ee81df2008-05-17 18:14:43 +00004179- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004180 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004181
Vinay Sajip8549ce32007-05-06 17:53:37 +00004182- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004183 setting a plain string, ie don't expand to single letter identifiers.
4184
Raymond Hettinger13936692007-04-11 18:40:58 +00004185- Request #1191699: Slices can now be pickled.
4186
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004187- Request #1193128: str.translate() now allows a None argument for
4188 translations that only remove characters without re-mapping the
4189 remaining characters.
4190
Georg Brandl5cb76c12007-03-21 09:00:39 +00004191- Patch #1682205: a TypeError while unpacking an iterable is no longer
4192 masked by a generic one with the message "unpack non-sequence".
4193
Neal Norwitzaa754b72007-03-21 06:39:48 +00004194- Remove unused file Python/fmod.c.
4195
Guido van Rossum143b5642007-03-23 04:58:42 +00004196- Bug #1683368: The object.__init__() and object.__new__() methods are
4197 now stricter in rejecting excess arguments. The only time when
4198 either allows excess arguments is when it is not overridden and the
4199 other one is. For backwards compatibility, when both are
4200 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004201 warning later). Also, type.__init__() insists on the same signature
4202 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004203
Georg Brandl3ee81df2008-05-17 18:14:43 +00004204- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4205 object to complex using its __complex__() method before falling back
4206 to the __float__() method. Therefore, the functions in the cmath
4207 module now can operate on objects that define a __complex__()
4208 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004209
Georg Brandl3ee81df2008-05-17 18:14:43 +00004210- Patch #1623563: allow __class__ assignment for classes with
4211 __slots__. The old and the new class are still required to have the
4212 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004213
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004217- Patch #1462488: Python no longer segfaults when
4218 ``object.__reduce_ex__()`` is called with an object that is faking
4219 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004220
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00004224- Patch #1444529: the builtin compile() now accepts keyword arguments.
4225
Georg Brandl7b9c5552007-03-12 14:30:05 +00004226- Bug #1678647: write a newline after printing an exception in any
4227 case, even when converting the value to a string failed.
4228
Georg Brandl871f1bc2007-03-12 13:17:36 +00004229- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004230 its argument, if it exists. If not, it will work like before. This
4231 allows customizing the output of dir() in the presence of a
4232 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004233
Collin Winter276887b2007-03-12 16:11:39 +00004234- Patch #922167: Python no longer segfaults when faced with infinitely
4235 self-recursive reload() calls (as reported by bug #742342).
4236
Georg Brandl3ee81df2008-05-17 18:14:43 +00004237- Patch #1675981: remove unreachable code from ``type.__new__()``
4238 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004240- Patch #1491866: change the complex() constructor to allow
4241 parthensized forms. This means complex(repr(x)) now works instead of
4242 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004243

4753 ".cpp" too.
4754
Facundo Batistad918a652007-04-24 13:54:38 +00004755- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004756 the client's request was successfully received, understood, and
4757 accepted. Now in these cases no error is raised in urllib (issue
4758 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004759

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004766- Added a timeout parameter to the constructor of other protocols
4767 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4768 work started with create_connection() and timeout in httplib, and
4769 closes patch #723312.
4770
Vinay Sajip8549ce32007-05-06 17:53:37 +00004771- Patch #1676823: Added create_connection() to socket.py, which may be
4772 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004773 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004774
Martin v. Löwis0af33882007-03-23 13:27:15 +00004775- Bug #978833: Revert r50844, as it broke _socketobject.dup.

4795
Georg Brandlf66b6032007-03-14 08:27:52 +00004796- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004797 AttributeError instead of an IOError when the server's response
4798 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004799
Georg Brandl3ee81df2008-05-17 18:14:43 +00004800- Patch #957650: "%var%" environment variable references are now
4801 properly expanded in ntpath.expandvars(), also "~user" home
4802 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00004803
Georg Brandl3ee81df2008-05-17 18:14:43 +00004804- Patch #1429539: pdb now correctly initializes the __main__ module
4805 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004806 correctly now.
4807
Georg Brandlbad6f192007-03-13 21:32:56 +00004808- The nonobvious commands.getstatus() function is now deprecated.

4814
Georg Brandl3ee81df2008-05-17 18:14:43 +00004815- Patch #1530482: add pydoc.render_doc() which returns the
4816 documentation for a thing instead of paging it to stdout, which
4817 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004818
Georg Brandl3ee81df2008-05-17 18:14:43 +00004819- Patch #1533909: the timeit module now accepts callables in addition

4826 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00004828- Patch #1581073: add a flag to textwrap that prevents the dropping of
4829 whitespace while wrapping.
4830
Georg Brandl92a6bae2007-03-13 17:43:32 +00004831- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004832 are set for invalid interpolation sequences that would lead to
4833 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004834

4847
Georg Brandl94fe3f52007-03-13 09:32:11 +00004848- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00004849 field names in its exception message if you try to write a record
4850 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004868

4876 returned string up to the first NUL character.

4887
Georg Brandl3ee81df2008-05-17 18:14:43 +00004888- unittest now verifies more of its assumptions. In particular,
4889 TestCase and TestSuite subclasses (not instances) are no longer
4890 accepted in TestSuite.addTest(). This should cause no
4891 incompatibility since it never made sense with ordinary subclasses
4892 -- the failure just occurred later, with a more cumbersome
4893 exception.

4903
Georg Brandl3ee81df2008-05-17 18:14:43 +00004904- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00005282 time so that opening a database previously created with the DB_DUP
5283 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5284 opens. Specifically: dictionary assignment to a DB object will
5285 replace all values for a given key when the database allows
5286 duplicate values. DB users should use DB.put(k, v) when they want
5287 to store duplicates; not DB[k] = v.

5294 characters with ASCII value less than 32. Also, it correctly quotes
5295 dots only if they occur on a single line, as opposed to the previous
5296 behavior of quoting dots if they are the second character of any
5297 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005298
