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
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000015- Ensure that tokenization of identifiers is not affected by locale.
16
Tarek Ziadé00002952010-04-03 08:37:59 +000017- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
18
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000019- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
20
Eric Smithd44b2fc2010-04-02 12:30:56 +000021- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
22 is called with a non-empty format string. This is an effort to
23 future-proof user code. If a derived class does not currently
24 implement __format__ but later adds its own __format__, it would
25 most likely break user code that had supplied a format string. This
26 will be changed to a DeprecationWaring in Python 3.3 and it will be
27 an error in Python 3.4.
28
Antoine Pitroua57df2c2010-03-31 21:32:15 +000029- Issue #8268: Old-style classes (not just instances) now support weak
30 references.
31
Victor Stinner6cbf90f2010-03-25 00:21:53 +000032- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
33 optimizations are disabled when --with-pydebug is used.
34
Victor Stinnerc7790ed2010-03-22 12:36:28 +000035- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000036
Benjamin Peterson96545892010-03-21 20:21:00 +000037- Issue #6474: Make error message from passing an inadequate number of keyword
38 arguments to a function correct.
39
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000040- Issue #8164: Don't allow lambda functions to have a docstring.
41
Victor Stinner66644262010-03-10 22:30:19 +000042- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000043 (SIGINT). If an error occurs while importing the site module, the error is
44 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000045 module.
46
Collin Winter001a3952010-03-18 21:54:01 +000047- Code objects now support weak references.

50-------
51
Benjamin Peterson76a23c12010-04-04 23:23:22 +000052- Issue #8310: Allow dis to examine new style classes.
53
Mark Dickinson8a950712010-04-03 15:47:46 +000054- Issue #8257: The Decimal construct now accepts a float instance
55 directly, converting that float to a Decimal of equal value:
56
57 >>> Decimal(1.1)
58 Decimal('1.100000000000000088817841970012523233890533447265625')
59
Raymond Hettinger34c35b22010-04-03 10:22:00 +000060- collections.Counter() now supports a subtract() method.
61
Raymond Hettingera551f312010-04-04 18:34:45 +000062- the functools module now has a total_ordering() class decorator
63 to simplify the specifying rich comparisons.
64
Raymond Hettingerbb006cf2010-04-04 21:45:01 +000065- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +000066 old-style comparison functions to new-style key-functions.
67
Mark Dickinson7c63eee2010-04-02 22:27:36 +000068- Issue #8294: The Fraction constructor now accepts Decimal and float
69 instances directly.
70
Mark Dickinsone096e822010-04-02 10:17:07 +000071- Issue #7279: Comparisons involving a Decimal signaling NaN now
72 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000073 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
74 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000075
Mark Dickinson99d80962010-04-02 08:53:22 +000076- Issue #2531: Comparison operations between floats and Decimal
77 instances now return a result based on the numeric values of the
78 operands; previously they returned an arbitrary result based on
79 the relative ordering of id(float) and id(Decimal).
80
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000081- Issue #8233: When run as a script, py_compile.py optionally takes a single
82 argument `-` which tells it to read files to compile from stdin. Each line
83 is read on demand and the named file is compiled immediately. (Original
84 patch by Piotr Ożarowski).
85
86- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
87 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000088
Florent Xicluna58b65662010-03-30 16:29:03 +000089- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
90 form feed (0x0C) are now considered linebreaks, as specified in Unicode
91 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +000092 http://www.unicode.org/reports/tr14/
93
Mark Dickinson9588d992010-03-27 11:14:37 +000094- Comparisons using one of <, <=, >, >= between a complex instance and
95 a Fractions instance now raise TypeError instead of returning
96 True/False. This makes Fraction <=> complex comparisons consistent with
97 int <=> complex, float <=> complex, and complex <=> complex comparisons.
98
Michael Foorde6410c52010-03-29 20:04:23 +000099- Addition of ``WeakSet`` to the ``weakref`` module.
100
Vinay Sajipb0623d62010-03-24 14:31:21 +0000101- logging: Added LOG_FTP to SysLogHandler and updated documentation.
102
Florent Xicluna176cda12010-03-22 22:52:11 +0000103- Issue #8205: Remove the "Modules" directory from sys.path when Python is
104 running from the build directory (POSIX only).
105
Florent Xiclunae1f4c922010-03-22 22:45:50 +0000106- Issue #7667: Fix doctest failures with non-ASCII paths.
107
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000108- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
109 didn't support chflags() (for example ZFS under FreeBSD). The error is
110 now silenced.
111
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000112- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
113 deprecated.
114
R. David Murrayc9d1a782010-03-22 15:55:09 +0000115- Issue #7860: platform.uname now reports the correct 'machine' type
116 when Python is running in WOW64 mode on 64 bit Windows.
117
Vinay Sajip804899b2010-03-22 15:29:01 +0000118- logging: Added getChild utility method to Logger and added isEnabledFor
119 method to LoggerAdapter.
120
Vinay Sajip31e928e2010-03-22 13:02:28 +0000121- Issue #8201: logging: Handle situation of non-ASCII and Unicode
122 logger names existing at the same time, causing a Unicode error
123 when configuration code attempted to sort the existing loggers.
124
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000125- Issue #8200: logging: Handle errors when multiprocessing is not
126 fully loaded when logging occurs.
127
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000128- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
129 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
130 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000131
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000132- Issue #8179: Fix macpath.realpath() on a non-existing path.
133
Florent Xicluna2e0a53f2010-03-18 21:50:06 +0000134- Issue #8024: Update the Unicode database to 5.2.

Antoine Pitroud7b731d2010-03-17 22:45:39 +0000136- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support
137 writing into objects supporting the new buffer API, for example bytearrays
138 or memoryviews.
139
Matthias Klose8b411682010-03-16 10:48:52 +0000140- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox

144
Matthias Klose358e7ff2010-03-15 13:42:23 +0000145- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
146 the locale.
147
Georg Brandlba83f822010-03-14 09:50:54 +0000148- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000149 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000150 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000151
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000152- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000153 for ``TimedRotatingFileHandler`` by using the modification time of an
154 existing log file to compute the next rollover time. If the log file does
155 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000156
Georg Brandlba83f822010-03-14 09:50:54 +0000157- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Florent Xicluna47627d52010-03-08 15:20:28 +0000163 classes.
164
Georg Brandlba83f822010-03-14 09:50:54 +0000165- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
166 a base64 transfer-encoded payload *after* decoding it; it no longer does.
167 This is a behavior change, so email's minor version number is now bumped, to
168 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000169

Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000184- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
185
Jesus Cea6557aac2010-03-22 14:22:26 +0000186- Issue #8156: bsddb module updated to version 4.8.4.

Matthias Klose817acef2010-03-15 00:02:36 +0000190- Issue #8142: Update libffi to the 3.0.9 release.
191
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000192- Issue #8300: When passing a non-integer argument to struct.pack with any
193 integer format code, struct.pack first attempts to convert the non-integer
194 using its __index__ method. If that method is non-existent or raises
195 TypeError it goes on to try the __int__ method, as described below.
196
Georg Brandlba83f822010-03-14 09:50:54 +0000197- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
198 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
199 argument's __int__ method to convert to an integer before packing. It also
200 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
201 was inconsistent: __int__ was used for some integer codes but not for others,
202 and the set of integer codes for which it was used differed between native
203 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000204
Brian Curtin19479fa2010-04-02 21:51:37 +0000205- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a

Georg Brandlba83f822010-03-14 09:50:54 +0000211- Issue #7993: Add a test of IO packet processing bandwidth to ccbench. It
212 measures the number of UDP packets processed per second depending on the
213 number of background CPU-bound Python threads.
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000214

Martin v. Löwisbf0dfb32010-04-01 07:40:51 +0000220- Issue #8032: For gdb7, a python-gdb.py file is added to the build,
221 allowing to use advanced gdb features when debugging Python.
222
Antoine Pitrouf83b3082010-03-21 19:19:41 +0000223- Issue #1628484: The Makefile doesn't ignore the CFLAGS environment
224 variable anymore. It also forwards the LDFLAGS settings to the linker
225 when building a shared library.
226
Martin v. Löwis24e4e162010-03-15 13:00:17 +0000227- Issue #6716: Quote -x arguments of compileall in MSI installer.

235 function declaration, which was kept for backwards compatibility reasons,
236 is now removed (the macro was introduced in 1997!).
237
Larry Hastings402b73f2010-03-25 00:54:54 +0000238- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000239 from Python 3.1. All existing Python CObjects in the main distribution
240 have been converted to capsules. To address backwards-compatibility
241 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

Georg Brandlba83f822010-03-14 09:50:54 +0000487 file position when calling `truncate()`. It would previously change the file

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

497 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

585Core and Builtins
586-----------------
587
Georg Brandlba83f822010-03-14 09:50:54 +0000588- The ``__complex__()`` method is now looked up on the class of instances to
589 make it consistent with other special methods.

593
Mark Dickinson1b34d252010-01-01 17:27:30 +0000594- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000595 DeprecationWarning when passed a float argument where an integer was expected.
596 These functions and methods now raise TypeError instead. The majority of the
597 effects of this change are in the extension modules, but some core functions
598 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
599 and many unicode/str methods.

613 of integers: the result of a/b is now correctly rounded for ints a and b (at
614 least on IEEE 754 platforms), and in particular does not depend on the
615 internal representation of a long.

623
Georg Brandlba83f822010-03-14 09:50:54 +0000624 These executables now work properly with the arch(1) command: ``arch -ppc
625 python`` will start a universal binary version of python in PPC mode (unlike
626 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000768- Remove switch from "%f" formatting to "%g" formatting for floats larger than

773 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +0000782- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
783 decimal string that's guaranteed to round back to x under correct rounding
784 (with round-half-to-even rounding mode). Previously it gave a string based on
785 rounding x to 17 decimal digits. repr(x) for a complex number behaves
786 similarly. On platforms where the correctly-rounded strtod and dtoa code is
787 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +0000789- Issue #7117: On almost all platforms: float-to-string and string-to-float
790 conversions within Python are now correctly rounded. Places these conversions
791 occur include: str for floats and complex numbers; the float and complex
792 constructors; old-style and new-style numeric formatting; serialization and
793 deserialization of floats and complex numbers using marshal, pickle and json;
794 parsing of float and imaginary literals in Python code; Decimal-to-float
795 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000796
Georg Brandlba83f822010-03-14 09:50:54 +0000797 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
798 providing correctly-rounded strtod and dtoa C functions. This code is
799 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
800 the C compiler. There may be a small number of platforms on which correct
801 operation of this code cannot be guaranteed, so the code is not used: notably,
802 this applies to platforms where the C double format is not IEEE 754 binary64,
803 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
804 and Python's configure script is unable to determine how to change the FPU
805 precision. On these platforms conversions use the platform strtod and dtoa,
806 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000808- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
809 uses the correctly-rounded string <-> float conversions described above (when
810 available), and so produces correctly rounded results that will display nicely
811 under the float repr. There are two related small changes: (1) round now
812 accepts any class with an ``__index__()`` method for its second argument (but
813 no longer accepts floats for the second argument), and (2) an excessively
814 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
815 raises an exception.

2600 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

2625 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2626 when given a tuple of classes as second argument, were looking up
2627 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2628 type object.
2629

2699 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2700 for catch_warnings() also led to an improvement in the raising of a
2701 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002767What's New in Python 2.6 beta 3?
2768================================
2769
Barry Warsaw07a4a382008-08-21 01:15:08 +00002770*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002771
2772Core and Builtins
2773-----------------
2774
Guido van Rossumf8402962008-08-20 15:01:50 +00002775- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2776 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2777 extensions do not automatically benefit from the class attribute
2778 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2779 to their tp_flags field if they care. This is a backwards
2780 compatibility feature; in 3.0, all types will use the cache by
2781 default.
2782
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002783- Keyword arguments can now follow starred arguments. (``f(a, *args,
2784 keyword=23)`` is now valid syntax.)
2785
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002786- ctypes function pointers that are COM methods have a boolean True
2787 value again.
2788
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002789- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2790 by denying s# to parse objects that have a releasebuffer procedure,
2791 and introducing s*.
2792
Georg Brandl1e13ea92008-08-11 09:07:59 +00002793- Issue #3537: Fix an assertion failure when an empty but presized dict
2794 object was stored in the freelist.
2795
Mark Dickinsonb6467572008-08-04 21:30:09 +00002796- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2797 ValueError consistently across platforms.
2798
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002799- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2800 (64bit Unix, for example), unichr() would truncate its argument and return
2801 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2802
Neal Norwitze7d8be82008-07-31 17:17:14 +00002803- Apply security patches from Apple.
2804
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002805- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2806 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2807
Antoine Pitrou92f82162008-07-25 22:22:08 +00002808- Issue #1819: function calls with several named parameters are now on
2809 average 35% faster (as measured by pybench).
2810
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002811- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2812 the python debugger steps into a class statement: the free variables (local
2813 variables defined in an outer scope) would be deleted from the outer scope.
2814
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002815- Issue #2620: Overflow checking when allocating or reallocating memory
2816 was not always being done properly in some python types and extension
2817 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2818 all been updated to perform better checks and places in the code that
2819 would previously leak memory on the error path when such an allocation
2820 failed have been fixed.

2824
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002825- Issue #3612: Added some missing basic types in ctypes.wintypes.
2826
Benjamin Petersone977ad42008-08-20 01:42:01 +00002827- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2828 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2829
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002830- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2831 version reported by these tools does not necessarily follow the python
2832 version numbering scheme, so the module is less strict when parsing it.
2833
Nick Coghlanf70385a2008-08-18 12:42:46 +00002834- Issue #2235: Added Py3k warnings for types which will become unhashable
2835 under the stricter __hash__ inheritance rules in 3.0. Several types
2836 which did not meet the rules for hash invariants and were already
2837 unhashable in 3.0 have now been explicitly flagged as unhashable in
2838 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2839 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2840
Brett Cannon88f801d2008-08-18 00:46:22 +00002841- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2842 imported into the module but exposed as part of the module's API.
2843
Brett Cannon7b96f072008-08-18 00:41:11 +00002844- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2845
Brett Cannon46225e72008-08-18 00:36:52 +00002846- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002848- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2849
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002850- Issue #3575: Incremental decoder's decode function now takes bytearray
2851 by using 's*' instead of 't#'.
2852
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002853- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002854 fails unicode conversion on 2nd parameter. (windows only)
2855
Facundo Batista94f243a2008-08-17 03:38:39 +00002856- Issue 2464. urllib2 now supports a malformation in the URL received
2857 in a redirect.
2858
Brett Cannonabe423e2008-08-16 21:47:07 +00002859- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002860 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002861
Facundo Batistaeb90b782008-08-16 14:44:07 +00002862- Issue #2776: fixed small issue when handling an URL with double slash
2863 after a 302 response in the case of not going through a proxy.
2864
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002865- Issue #2676: in the email package, content-type parsing was hanging on
2866 pathological input because of quadratic or exponential behaviour of a
2867 regular expression.
2868
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002869- Issue #3476: binary buffered reading through the new "io" library is now
2870 thread-safe.
2871
Brett Cannonbf3157b2008-08-14 05:00:03 +00002872- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2873 since mimetools itself is deprecated. Because modules are cached, all
2874 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2875
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002876- Issue #3134: shutil referenced undefined WindowsError symbol.
2877
Robert Schuppenies14646332008-08-10 11:01:53 +00002878- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2879 menu entries were not deleted.
2880
Brett Cannon83e81842008-08-09 23:30:55 +00002881- Copied the implementation of reduce() to _functools.reduce() to have a
2882 version that did not raise a DeprecationWarning under -3.
2883
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002884- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2885 a MemoryError rather than silently stop the iteration.
2886
Guido van Rossum59ce9012008-08-09 14:55:34 +00002887- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2888 to _sre.compile() will now be rejected. This should not affect anybody
2889 since the re.compile() function never generates invalid re-bytecode.
2890
Skip Montanaroa032bf42008-08-08 22:52:51 +00002891- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2892 upon first access it can be automatically initialized from the csv file if
2893 it wasn't initialized during instantiation.
2894
Brett Cannon3aa2a492008-08-06 22:28:09 +00002895- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2896 the reload() built-in has been removed.
2897
Brett Cannon7e30b672008-08-04 21:52:25 +00002898- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002899 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002910 asking for a specific length. This problem only affected files opened

2967-----------------
2968
Georg Brandl3e483f62008-07-16 22:57:41 +00002969- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2970 its methods now allow for items objects that can be converted to
2971 an integer using operator.index().
2972
Mark Dickinson64b7e502008-07-16 09:40:03 +00002973- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2974 produced a ValueError instead of giving the correct float.
2975
Eric Smitha5fa5a22008-07-16 00:11:49 +00002976- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2977 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2978
Mark Dickinson7103aa42008-07-15 19:08:33 +00002979- Issue #3008: the float type has a new instance method 'float.hex'
2980 and a new class method 'float.fromhex' to convert floating-point
2981 numbers to and from hexadecimal strings, respectively.
2982
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002983- Issue #2235: __hash__ is once again inherited by default. To allow
2984 collections.Hashable to remain meaningful in the presence of the
2985 default hash implementation (object.__hash__), it is now possible
2986 to explicit block inheritance of hash by setting __hash__=None at
2987 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2988 level.
2989
Nick Coghlanb028f502008-07-13 14:52:36 +00002990- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2991 the parent module cannot be found while performing an absolute import.
2992 This means that an incorrectly defined __package__ attribute will
2993 now only prevent relative imports in that module rather than causing
2994 all imports from that module to fail.
2995
Nick Coghlan14ff9942008-07-08 14:21:42 +00002996- Issue #2517: Allow unicode messages in Exceptions again by correctly

3006 another thread's dictionary.
3007
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003008- Issue #3004: Minor change to slice.indices(): the start and stop
3009 arguments are now treated identically, making the behaviour easier
3010 to describe and understand. For example, slice(None, -10,
3011 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3012 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3013 10, -1).
3014
Georg Brandl278fc502008-07-19 12:46:12 +00003015- Issue #3219: Calling a function with repeated keyword arguments,
3016 f(a=2, a=23), would not cause a syntax error. This was a regression
3017 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003055- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3056 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003057 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003058 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003074- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3487- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003488
3489- The PyString functions have been renamed to PyBytes. A batch of
3490 defines were added so that the linker still sees the original
3491 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003529- Issue #1631171: Re-implement the 'warnings' module in C (the
3530 original Python code has been kept as backup). This will allow for
3531 using the 'warning's machinery in such places as the parser where
3532 use of pure Python code is not possible. Both the ``showarning()``
3533 and ``formatwarning()`` gain an optional 'line' argument which is
3534 not called by default for backwards-compatibility reasons. Setting
3535 ``warnings.showwarning()`` to an implementation that lacks support
3536 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003578- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003579 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003599- Issue #2550: The approach used by client/server code for obtaining
3600 ports to listen on in network-oriented tests has been refined in an
3601 effort to facilitate running multiple instances of the entire
3602 regression test suite in parallel without issue.
3603 test_support.bind_port() has been fixed such that it will always
3604 return a unique port -- which wasn't always the case with the
3605 previous implementation, especially if socket options had been set
3606 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3607 new implementation of bind_port() will actually raise an exception
3608 if it is passed an AF_INET/SOCK_STREAM socket with either the
3609 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3610 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3611 the socket it's been passed. This currently only applies to
3612 Windows. This option prevents any other sockets from binding to the
3613 host/port we've bound to, thus removing the possibility of the
3614 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3615 when a second SOCK_STREAM socket binds and accepts to a host/port
3616 that's already been bound by another socket. The optional preferred
3617 port parameter to bind_port() has been removed. Under no
3618 circumstances should tests be hard coding ports!
3619
3620 test_support.find_unused_port() has also been introduced, which will
3621 pass a temporary socket object to bind_port() in order to obtain an
3622 unused port. The temporary socket object is then closed and
3623 deleted, and the port is returned. This method should only be used
3624 for obtaining an unused port in order to pass to an external program
3625 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3626 a parameter to a server-oriented class that doesn't give you direct
3627 access to the underlying socket used.
3628
3629 Finally, test_support.HOST has been introduced, which should be used
3630 for the host argument of any relevant socket calls (i.e. bind and
3631 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003632
3633 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003634 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003635 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3636 test_asynchat and test_socket_ssl.
3637
Georg Brandl3ee81df2008-05-17 18:14:43 +00003638 It is now possible for multiple instances of the regression test
3639 suite to run in parallel without issue.

3907
Fred Drakea8ee94b2008-03-01 02:45:07 +00003908- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003909 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003914
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003915- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003916 issue 215555 for a discussion.
3917
Eric Smitha73fbe72008-02-23 03:09:44 +00003918- Added the future_builtins module, which contains hex() and oct().
3919 These are the PEP 3127 version of these functions, designed to be
3920 compatible with the hex() and oct() builtins from Python 3.0. They
3921 differ slightly in their output formats from the existing, unchanged
3922 Python 2.6 builtins. The expected usage of the future_builtins
3923 module is:
3924 from future_builtins import hex, oct
3925
Eric Smith7ef40bf2008-02-20 23:34:22 +00003926- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3927 exponents for exponents with absolute value < 100. Follows C99
3928 standard. This is a change on Windows, which would use 3 digits.
3929 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3930 so that any alterations it does to the resulting string will be
3931 available in stringlib/formatter.h (for float.__format__).
3932
Eric Smith5a3c1352008-02-19 13:21:56 +00003933- Implemented PEP 3101, Advanced String Formatting. This adds a new
3934 builtin format(); a format() method for str and unicode; a
3935 __format__() method to object, str, unicode, int, long, float, and
3936 datetime; the class string.Formatter; and the C API
3937 PyObject_Format().
3938
Georg Brandl3ee81df2008-05-17 18:14:43 +00003939- Fixed several potential crashes, all caused by specially crafted
3940 __del__ methods exploiting objects in temporarily inconsistent
3941 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003942
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003943- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003944 prevent a possible crash: an Abstract Base Class would try to access
3945 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003950- Clear all free lists during a gc.collect() of the highest generation
3951 in order to allow pymalloc to free more arenas. Python may give back
3952 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003953
Georg Brandl3ee81df2008-05-17 18:14:43 +00003954- Issue #2045: Fix an infinite recursion triggered when printing a
3955 subclass of collections.defaultdict, if its default_factory is set
3956 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003957
Christian Heimesf75dbef2008-02-08 00:11:31 +00003958- Fixed a minor memory leak in dictobject.c. The content of the free
3959 list was not freed on interpreter shutdown.
3960
Georg Brandl21e99f42010-03-07 15:23:59 +00003961- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00003963
Georg Brandl3ee81df2008-05-17 18:14:43 +00003964- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3965 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003966 to compact the internal free lists of pre-allocted ints and floats.
3967
Georg Brandl3ee81df2008-05-17 18:14:43 +00003968- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3969 calls. Python expected the return type int but the fork familie
3970 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003971

Georg Brandl3ee81df2008-05-17 18:14:43 +00003984- Patch #1473257: generator objects gain a gi_code attribute. This is
3985 the same object as the func_code attribute of the function that
3986 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003987
Georg Brandl3ee81df2008-05-17 18:14:43 +00003988- Issue #1920: "while 0" statements were completely removed by the
3989 compiler, even in the presence of an "else" clause, which is
3990 supposed to be run when the condition is false. Now the compiler
3991 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00003993- A few crashers fixed: weakref_in_del.py (issue #1377858);
3994 loosing_dict_ref.py (issue #1303614, test67.py);
3995 borrowed_ref_[34].py (not in tracker).
3996
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003997- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003998 suppressed while an extension is loaded by calling SetErrorMode in
3999 dynload_win.c. The error is still reported properly.
4000
Georg Brandl3ee81df2008-05-17 18:14:43 +00004001- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004002 several extension methods and modules do not work without unicode
4003 support.
4004
Georg Brandl26543b12008-01-21 18:36:51 +00004005- Issue #1882: when compiling code from a string, encoding cookies in the
4006 second line of code were not always recognized correctly.
4007
Georg Brandl14404b62008-01-19 19:27:05 +00004008- Issue #1679: "0x" was taken as a valid integer literal.
4009
Georg Brandl6caad7d2008-01-26 14:19:22 +00004010- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004011 added.
4012
Christian Heimesc94e2b52008-01-14 04:13:37 +00004013- sys.float_info / PyFloat_GetInfo: The floating point information
4014 object was converted from a dict to a specialized structseq object.
4015
Georg Brandl3ee81df2008-05-17 18:14:43 +00004016- Patch #1816: Added sys.flags structseq. It exposes the status of
4017 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004018
Georg Brandl3ee81df2008-05-17 18:14:43 +00004019- Objects/structseq.c: Implemented new structseq representation. The
4020 patch makes structseqs (e.g. the return value of os.stat) more
4021 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004022
Georg Brandl3ee81df2008-05-17 18:14:43 +00004023- Patch #1700288: added a type attribute cache that caches method
4024 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004025
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004026- Bug #1776: __import__() no longer accepts filenames on any platform.
4027 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004028
Georg Brandlaed6c662008-01-07 17:25:53 +00004029- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4030
Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4032 envvar and sys.dont_write_bytecode attribute. All these can be set
4033 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004034
Georg Brandl3ee81df2008-05-17 18:14:43 +00004035- Improve some exception messages when Windows fails to load an
4036 extension module. Now we get for example '%1 is not a valid Win32
4037 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004038
Georg Brandl3ee81df2008-05-17 18:14:43 +00004039- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004041- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4042 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004043
Christian Heimes0a8143f2007-12-18 23:22:54 +00004044- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004045 and INF. float("nan"), float("inf") and float("-inf") now work on
4046 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004047
Georg Brandl3ee81df2008-05-17 18:14:43 +00004048- Compiler now generates simpler and faster code for dictionary
4049 literals. The oparg for BUILD_MAP now indicates an estimated
4050 dictionary size. There is a new opcode, STORE_MAP, for adding
4051 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004052
Georg Brandl3ee81df2008-05-17 18:14:43 +00004053- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00004054
Georg Brandl3ee81df2008-05-17 18:14:43 +00004055- Issue #1620: New property decorator syntax was modifying the
4056 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004057
Georg Brandl3ee81df2008-05-17 18:14:43 +00004058- Issue #1538: Avoid copying string in split/rsplit if the split char
4059 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004060
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004061- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004062 SystemError.
4063
Nick Coghlanef01d822007-12-03 12:55:17 +00004064- PEP 366: Allow explicit relative imports when executing modules
4065 inside packages with the -m switch via a new module level
4066 __package__ attribute.
4067
Georg Brandl3ee81df2008-05-17 18:14:43 +00004068- Issue #1402: Fix a crash on exit, when another thread is still
4069 running, and if the deallocation of its frames somehow calls the
4070 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004071

4073
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00004074- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004075 attribute of an empty cell object.
4076
Georg Brandl3ee81df2008-05-17 18:14:43 +00004077- Issue #1460: The utf-7 incremental decoder did not accept truncated
4078 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004079
Georg Brandl3ee81df2008-05-17 18:14:43 +00004080- Patch #1739468: Directories and zipfiles containing a __main__.py
4081 file can now be directly executed by passing their name to the
4082 interpreter. The directory/zipfile is automatically inserted as the
4083 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004084
Georg Brandl3ee81df2008-05-17 18:14:43 +00004085- Issue #1265: Fix a problem with sys.settrace, if the tracing
4086 function uses a generator expression when at the same time the
4087 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004088
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004089- sets and frozensets now have an isdisjoint() method.
4090
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004091- optimize the performance of builtin.sum().
4092
Neal Norwitz44f326e2007-10-05 05:29:17 +00004093- Fix warnings found by the new version of the Coverity checker.
4094
Georg Brandl21e99f42010-03-07 15:23:59 +00004095- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004096 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4097 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004098
Georg Brandl3ee81df2008-05-17 18:14:43 +00004099- Issue #1686386: Tuple's tp_repr did not take into account the
4100 possibility of having a self-referential tuple, which is possible
4101 from C code. Nor did object's tp_str consider that a type's tp_str
4102 could do something that could lead to an inifinite recursion.
4103 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4104 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004105
Georg Brandl3ee81df2008-05-17 18:14:43 +00004106- Issue #1164: It was possible to trigger deadlock when using the
4107 'print' statement to write to a file since the GIL was not released
4108 as needed. Now PyObject_Print() does the right thing along with
4109 various tp_print implementations of the built-in types and those in
4110 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004111
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112- Issue #1147: Exceptions were directly allowing string exceptions in
4113 their throw() method even though string exceptions no longer
4114 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004115
Georg Brandl3ee81df2008-05-17 18:14:43 +00004116- Issue #1096: Prevent a segfault from getting the repr of a very
4117 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004118
Brett Cannon1e534b52007-09-07 04:18:30 +00004119- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004120 PyObject_Call() never calling back out to Python code to trigger
4121 recursion depth updates/checks. Required the creation of a static
4122 RuntimeError instance in case normalizing an exception put the
4123 recursion check value past its limit. Fixes crashers
4124 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004125
Georg Brandl3ee81df2008-05-17 18:14:43 +00004126- Patch #1031213: Decode source line in SyntaxErrors back to its
4127 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00004129- Patch #1673759: add a missing overflow check when formatting floats
4130 with %G.
4131
Georg Brandl3ee81df2008-05-17 18:14:43 +00004132- Prevent expandtabs() on string and unicode objects from causing a
4133 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00004134

Georg Brandla5ea6892007-06-01 11:33:33 +00004138
Neal Norwitz0ac60192007-05-27 04:08:54 +00004139- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004140 __*__ attributes. (Some already existed, e.g., __doc__ and
4141 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004142
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004143- Add -3 option to the interpreter to warn about features that are
4144 deprecated and will be changed/removed in Python 3.0.
4145
Georg Brandl2134e752007-05-21 20:34:16 +00004146- Patch #1686487: you can now pass any mapping after '**' in function
4147 calls.
4148
Collin Winter62903052007-05-18 23:11:24 +00004149- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004150 "except E as target:". This is to provide forwards compatibility
4151 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004152
Brett Cannon229cee22007-05-05 01:34:02 +00004153- Deprecate BaseException.message as per PEP 352.
4154
Georg Brandl3ee81df2008-05-17 18:14:43 +00004155- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004156 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004157
Vinay Sajip8549ce32007-05-06 17:53:37 +00004158- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004159 setting a plain string, ie don't expand to single letter identifiers.
4160
Raymond Hettinger13936692007-04-11 18:40:58 +00004161- Request #1191699: Slices can now be pickled.
4162
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004163- Request #1193128: str.translate() now allows a None argument for
4164 translations that only remove characters without re-mapping the
4165 remaining characters.
4166
Georg Brandl5cb76c12007-03-21 09:00:39 +00004167- Patch #1682205: a TypeError while unpacking an iterable is no longer
4168 masked by a generic one with the message "unpack non-sequence".
4169
Neal Norwitzaa754b72007-03-21 06:39:48 +00004170- Remove unused file Python/fmod.c.
4171
Guido van Rossum143b5642007-03-23 04:58:42 +00004172- Bug #1683368: The object.__init__() and object.__new__() methods are
4173 now stricter in rejecting excess arguments. The only time when
4174 either allows excess arguments is when it is not overridden and the
4175 other one is. For backwards compatibility, when both are
4176 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004177 warning later). Also, type.__init__() insists on the same signature
4178 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004179
Georg Brandl3ee81df2008-05-17 18:14:43 +00004180- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4181 object to complex using its __complex__() method before falling back
4182 to the __float__() method. Therefore, the functions in the cmath
4183 module now can operate on objects that define a __complex__()
4184 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004185
Georg Brandl3ee81df2008-05-17 18:14:43 +00004186- Patch #1623563: allow __class__ assignment for classes with
4187 __slots__. The old and the new class are still required to have the
4188 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Patch #1642547: Fix an error/crash when encountering syntax errors
4191 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Patch #1462488: Python no longer segfaults when
4194 ``object.__reduce_ex__()`` is called with an object that is faking
4195 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Patch #1680015: Don't modify __slots__ tuple if it contains an
4198 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00004199
Georg Brandl5240d742007-03-13 20:46:32 +00004200- Patch #1444529: the builtin compile() now accepts keyword arguments.
4201
Georg Brandl7b9c5552007-03-12 14:30:05 +00004202- Bug #1678647: write a newline after printing an exception in any
4203 case, even when converting the value to a string failed.
4204
Georg Brandl871f1bc2007-03-12 13:17:36 +00004205- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004206 its argument, if it exists. If not, it will work like before. This
4207 allows customizing the output of dir() in the presence of a
4208 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004209
Collin Winter276887b2007-03-12 16:11:39 +00004210- Patch #922167: Python no longer segfaults when faced with infinitely
4211 self-recursive reload() calls (as reported by bug #742342).
4212
Georg Brandl3ee81df2008-05-17 18:14:43 +00004213- Patch #1675981: remove unreachable code from ``type.__new__()``
4214 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00004215
Georg Brandl3ee81df2008-05-17 18:14:43 +00004216- Patch #1491866: change the complex() constructor to allow
4217 parthensized forms. This means complex(repr(x)) now works instead of
4218 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004219
Georg Brandlaa2321b2007-03-07 00:40:28 +00004220- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221 makes the filenames the warning module prints much more sensible
4222 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004223
Georg Brandl49aafc92007-03-07 00:34:46 +00004224- Variant of patch #697613: don't exit the interpreter on a SystemExit
4225 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004226 variable is given, but break into the interactive interpreter just
4227 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00004228
Georg Brandl3ee81df2008-05-17 18:14:43 +00004229- Patch #1638879: don't accept strings with embedded NUL bytes in

4728 (as opposed to the command line) will now write file names ending in
4729 ".cpp" too.
4730
Facundo Batistad918a652007-04-24 13:54:38 +00004731- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004732 the client's request was successfully received, understood, and
4733 accepted. Now in these cases no error is raised in urllib (issue
4734 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004735

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004742- Added a timeout parameter to the constructor of other protocols
4743 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4744 work started with create_connection() and timeout in httplib, and
4745 closes patch #723312.
4746
Vinay Sajip8549ce32007-05-06 17:53:37 +00004747- Patch #1676823: Added create_connection() to socket.py, which may be
4748 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004749 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004750
Martin v. Löwis0af33882007-03-23 13:27:15 +00004751- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004758- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
4759 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00004760 directories.
4761

4771
Georg Brandlf66b6032007-03-14 08:27:52 +00004772- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004773 AttributeError instead of an IOError when the server's response
4774 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004775
Georg Brandl3ee81df2008-05-17 18:14:43 +00004776- Patch #957650: "%var%" environment variable references are now
4777 properly expanded in ntpath.expandvars(), also "~user" home
4778 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00004779
Georg Brandl3ee81df2008-05-17 18:14:43 +00004780- Patch #1429539: pdb now correctly initializes the __main__ module
4781 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004782 correctly now.
4783
Georg Brandlbad6f192007-03-13 21:32:56 +00004784- The nonobvious commands.getstatus() function is now deprecated.

4790
Georg Brandl3ee81df2008-05-17 18:14:43 +00004791- Patch #1530482: add pydoc.render_doc() which returns the
4792 documentation for a thing instead of paging it to stdout, which
4793 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004794
Georg Brandl3ee81df2008-05-17 18:14:43 +00004795- Patch #1533909: the timeit module now accepts callables in addition

4801 parameter which can be set to False to prevent the default
4802 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00004803
Georg Brandl9e6b4702007-03-13 18:15:41 +00004804- Patch #1581073: add a flag to textwrap that prevents the dropping of
4805 whitespace while wrapping.
4806
Georg Brandl92a6bae2007-03-13 17:43:32 +00004807- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004808 are set for invalid interpolation sequences that would lead to
4809 errors on reading back those values.

Collin Winter22c42ba2007-03-10 02:51:26 +00004844

4852 returned string up to the first NUL character.

4863
Georg Brandl3ee81df2008-05-17 18:14:43 +00004864- unittest now verifies more of its assumptions. In particular,
4865 TestCase and TestSuite subclasses (not instances) are no longer
4866 accepted in TestSuite.addTest(). This should cause no
4867 incompatibility since it never made sense with ordinary subclasses
4868 -- the failure just occurred later, with a more cumbersome
4869 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00004870

4878 given a unicode argument and os.listdir() returns unicode filenames.
4879
Georg Brandl3ee81df2008-05-17 18:14:43 +00004880- Patch #1673619: setup.py identifies extension modules it doesn't
4881 know how to build and those it knows how to build but that fail to
4882 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005258 time so that opening a database previously created with the DB_DUP
5259 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5260 opens. Specifically: dictionary assignment to a DB object will
5261 replace all values for a given key when the database allows
5262 duplicate values. DB users should use DB.put(k, v) when they want
5263 to store duplicates; not DB[k] = v.

5270 characters with ASCII value less than 32. Also, it correctly quotes
5271 dots only if they occur on a single line, as opposed to the previous
5272 behavior of quoting dots if they are the second character of any
5273 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005651- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5652 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
