Georg Brandlbad09252010-09-05 21:29:17 +00005What's New in Python 3.2 Alpha 3?
6=================================
7
8*Release date: XX-Oct-2010*
9
10Core and Builtins
11-----------------
12
Brett Cannonbc2eff32010-09-19 21:39:02 +000013- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
14 module that was imported, but instead gets the module from sys.modules.
15
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +000016- Issue #9212: The range type_items now provides index() and count()
17 methods, to conform to the Sequence ABC. Patch by Daniel Urban and
18 Daniel Stutzbach.
19
Eric Smithe4d63172010-09-13 20:48:43 +000020- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
21 is called with a non-empty format string. This is an effort to
22 future-proof user code. If a derived class does not currently
23 implement __format__ but later adds its own __format__, it would
24 most likely break user code that had supplied a format string. This
25 will be changed to a DeprecationWaring in Python 3.3 and it will be
26 an error in Python 3.4.
27
Antoine Pitrou1df15362010-09-13 14:16:46 +000028- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
29 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
30 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
31
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +000032- Issue #9210: Configure option --with-wctype-functions was removed. Using the
33 functions from the libc caused the methods .upper() and lower() to become
34 locale aware and created subtly wrong results.
35
Victor Stinner1205f272010-09-11 00:54:47 +000036- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on
37 a non-ASCII byte in the format string.
38
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +000039- Issue #4617: Previously it was illegal to delete a name from the local
40 namespace if it occurs as a free variable in a nested block. This limitation
41 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
42
Antoine Pitroue4a18922010-09-09 20:30:23 +000043- Issue #9804: ascii() now always represents unicode surrogate pairs as
44 a single ``\UXXXXXXXX``, regardless of whether the character is printable
45 or not. Also, the "backslashreplace" error handler now joins surrogate
46 pairs into a single character on UCS-2 builds.
47
Antoine Pitrou6e6cc832010-09-09 12:59:39 +000048- Issue #9757: memoryview objects get a release() method to release the
49 underlying buffer (previously this was only done when deallocating the
50 memoryview), and gain support for the context management protocol.
51
Antoine Pitrou079ce542010-09-08 12:37:10 +000052- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
53 thread-local storage key.

56-------
57
Vinay Sajip83eadd12010-09-20 10:31:18 +000058- logging: Added hasHandlers() method to Logger and LoggerAdapter.
59
Florent Xiclunaeb19dce2010-09-18 23:34:07 +000060- Issue #1686: Fix string.Template when overriding the pattern attribute.
61
Antoine Pitrou98b46702010-09-18 22:59:00 +000062- Issue #9854: SocketIO objects now observe the RawIOBase interface in
63 non-blocking mode: they return None when an operation would block (instead
64 of raising an exception).
65
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +000066- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
67 another kind.
68
Vinay Sajip19ec67a2010-09-17 18:57:36 +000069- Issue #9441: logging has better coverage for rotating file handlers.
70
Raymond Hettinger35c87f22010-09-16 19:10:17 +000071- Issue #9865: collections.OrderedDict now has a __sizeof__ method.
72
Antoine Pitrou328ec742010-09-14 18:37:24 +000073- Issue #9854: The default read() implementation in io.RawIOBase now
74 handles non-blocking readinto() returning None correctly.
75
Antoine Pitrou9e0b8642010-09-14 18:00:02 +000076- Issue #1552: socket.socketpair() now returns regular socket.socket
77 objects supporting the whole socket API (rather than the "raw"
78 _socket.socket objects).
79
Antoine Pitroua468adc2010-09-14 14:43:44 +000080- Issue #9853: Fix the signature of SSLSocket.recvfrom() and
81 SSLSocket.sendto() to match the corresponding socket methods.
82
Raymond Hettinger98a5f3f2010-09-13 21:36:00 +000083- Issue 9840: Added a decorator to reprlib for wrapping __repr__ methods
84 to make them handle recursive calls within the same thread.
85
Vinay Sajipaf9d10a2010-09-13 20:40:30 +000086- logging: Enhanced HTTPHandler with secure and credentials initializers.
87
Victor Stinnere797c162010-09-17 23:34:26 +000088- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
Victor Stinnerccb706c2010-09-13 19:41:36 +000089
Antoine Pitrou6464d5f2010-09-12 14:51:20 +000090- Issue #9837: The read() method of ZipExtFile objects (as returned by
91 ZipFile.open()) could return more bytes than requested.
92
Raymond Hettingerdc08a142010-09-12 05:15:22 +000093- Issue #9826: OrderedDict.__repr__ can now handle self-referential
94 values: d['x'] = d.
95
Raymond Hettingerfa11db02010-09-12 04:12:42 +000096- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
97 it possible for the user to create self-referencing ordered dictionaries
98 which become permanently uncollectable GC garbage. Reinstated the Py3.1
99 approach of using weakref proxies so that reference cycles never get created
100 in the first place.
101
Victor Stinnercb043522010-09-10 23:49:04 +0000102- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
103 encode the value with filesystem encoding and surrogateescape (instead of
Victor Stinner6f7b7832010-09-10 23:50:31 +0000104 utf-8 in strict mode). Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +0000105
Victor Stinner5b519e02010-09-10 21:57:59 +0000106- Issue #9632: Remove sys.setfilesystemencoding() function: use
107 PYTHONFSENCODING environment variable to set the filesystem encoding at
108 Python startup. sys.setfilesystemencoding() creates inconsistencies because
109 it is unable to reencode all filenames in all objects.
110
Antoine Pitrouea99c5c2010-09-09 18:33:21 +0000111- Issue #9410: Various optimizations to the pickle module, leading to
112 speedups up to 4x (depending on the benchmark). Mostly ported from
113 Unladen Swallow; initial patch by Alexandre Vassalotti.
114
Raymond Hettingerbad3c882010-09-09 12:31:00 +0000115- The pprint module now supports printing OrderedDicts in their given
116 order (formerly, it would sort the keys).
117
Vinay Sajip121a1c42010-09-08 10:46:15 +0000118- Logging: Added QueueHandler class to facilitate logging usage with
119 multiprocessing.
120
Antoine Pitrou783eea72010-09-07 22:06:17 +0000121- Issue #9707: Rewritten reference implementation of threading.local which
122 is friendlier towards reference cycles. This change is not normally
123 visible since an optimized C implementation (_thread._local) is used
124 instead.
125
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +0000126- Issue #6394: os.getppid() is now supported on Windows. Note that it will
127 still return the id of the parent process after it has exited. This process
128 id may even have been reused by another unrelated process.
129
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +0000130- Issue #9792: In case of connection failure, socket.create_connection()
131 would swallow the exception and raise a new one, making it impossible
132 to fetch the original errno, or to filter timeout errors. Now the
133 original error is re-raised.
134
Antoine Pitrou5e38aae2010-09-07 16:30:09 +0000135- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
136 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
137 be updated back after the system call. Original patch by Brian Brazil.
138
Raymond Hettinger435cb0f2010-09-06 23:36:31 +0000139- Updates to the random module:
140
141 * Document which parts of the module are guaranteed to stay the same
142 across versions and which parts are subject to change.
143
Raymond Hettingerf763a722010-09-07 00:38:15 +0000144 * Update the seed() method to use all of the bits in a string
Raymond Hettinger05156612010-09-07 04:44:52 +0000145 instead of just the hash value. This makes better use of the
146 seed value and assures the seeding is platform independent.
147 Issue #7889.
148
149 * Improved the random()-->integer algorithm used in choice(),
150 shuffle(), sample(), randrange(), and randint(). Formerly, it
151 used int(n*random()) which has a slight bias whenever n is not
152 a power of two. Issue #9025.
153
154 * Improved documentation of arguments to randrange(). Issue #9379.
Raymond Hettingerf763a722010-09-07 00:38:15 +0000155
Raymond Hettingerf45abc92010-09-06 21:26:09 +0000156- collections.OrderedDict now supports a new method for repositioning
157 keys to either end.
158
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +0000159- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest
160 test cases now also have assertWarns and assertWarnsRegexp methods to
161 check that a given warning type was triggered by the code under test.
162
Antoine Pitrou972ee132010-09-06 18:48:21 +0000163- Issue #5506: BytesIO objects now have a getbuffer() method exporting a
164 view of their contents without duplicating them. The view is both readable
165 and writable.
166
Brian Curtin62857742010-09-06 17:07:27 +0000167- Issue #7566: Implement os.path.sameopenfile for Windows.
168
Antoine Pitrou0d739d72010-09-05 23:01:12 +0000169- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
170 unsupported operation is attempted (for example, writing to a file open
171 only for reading).
172
Gregory P. Smith13b55292010-09-06 08:30:23 +0000173- hashlib has two new constant attributes: algorithms_guaranteed and
174 algorithms_avaiable that respectively list the names of hash algorithms
175 guaranteed to exist in all Python implementations and the names of hash
176 algorithms available in the current process.
177
Benjamin Peterson568867a2010-09-11 16:02:03 +0000178C-API
179-----
180
181- Issue #9834: Don't segfault in PySequence_GetSlice, PySequence_SetSlice, or
182 PySequence_DelSlice when the object doesn't have any mapping operations
183 defined.
184
Antoine Pitroub41e1282010-09-08 20:57:48 +0000185Tools/Demos
186-----------
187
188- Issue #9188: The gdb extension now handles correctly narrow (UCS2) as well
189 as wide (UCS4) unicode builds for both the host interpreter (embedded
190 inside gdb) and the interpreter under test.

196
Alexander Belopolsky4d770172010-09-13 18:14:34 +0000197- Issue #9315: Added tests for the trace module. Patch by Eli Bendersky.
198
Florent Xiclunadc69e722010-09-13 16:35:02 +0000199- Issue #9323: Make test.regrtest.__file__ absolute, this was not always the
200 case when running profile or trace, for example.

204
Hirokazu Yamamotoba45c2b2010-09-19 09:24:20 +0000205- Issue #9552: Avoid unnecessary rebuild of OpenSSL. (Windows)
206
Hirokazu Yamamoto234f88d2010-09-16 17:50:57 +0000207- Issue #9810: Compile bzip2 source files in python's project file
208 directly. It used to be built with bzip2's makefile.
209
Brett Cannonb82489d2010-09-14 19:41:23 +0000210- Issue #9848: Stopping trying to build _weakref in setup.py as it is a
211 built-in module.
212
Georg Brandlb084b482010-09-12 17:14:26 +0000213- Issue #9806: python-config now has an ``--extension-suffix`` option that
214 outputs the suffix for dynamic libraries including the ABI version name
215 defined by PEP 3149.
216
Antoine Pitrou8e6b4072010-09-10 19:44:44 +0000217- Issue #941346: Improve the build process under AIX and allow Python to
218 be built as a shared library. Patch by Sébastien Sablé.

230-----------------
231
Georg Brandl649971e2010-09-05 17:06:50 +0000232- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
233 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
234 bytecode is a bit simplified. Patch by Demur Rumed.
Antoine Pitrou74a69fa2010-09-04 18:43:52 +0000235
Brett Cannonef0e6c32010-09-04 18:24:04 +0000236- Issue #9766: Rename poorly named variables exposed by _warnings to prevent
237 confusion with the proper variables names from 'warnings' itself.
238
Georg Brandl649971e2010-09-05 17:06:50 +0000239- Issue #9212: dict_keys and dict_items now provide the isdisjoint() method, to
240 conform to the Set ABC. Patch by Daniel Urban.
Daniel Stutzbach045b3ba2010-09-02 15:06:06 +0000241
Georg Brandl649971e2010-09-05 17:06:50 +0000242- Issue #9737: Fix a crash when trying to delete a slice or an item from a
243 memoryview object.
Antoine Pitroue0793ba2010-09-01 21:14:16 +0000244
Georg Brandl649971e2010-09-05 17:06:50 +0000245- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
246 now removed, since their effect was inexistent in 3.x (the default encoding is
247 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +0000248
Antoine Pitroub0fa8312010-09-01 15:10:12 +0000249- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
250 properly. Patch by Stefan Behnel.
251
Georg Brandl649971e2010-09-05 17:06:50 +0000252- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
253 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +0000254
Benjamin Peterson33856de2010-08-30 14:41:20 +0000255- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
256
Benjamin Peterson0e102062010-08-25 23:13:17 +0000257- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.

Georg Brandl649971e2010-09-05 17:06:50 +0000262- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that
263 occur during attribute lookup are now propagated to the caller.
Benjamin Peterson17689992010-08-24 03:26:23 +0000264
Victor Stinner94908bb2010-08-18 21:23:25 +0000265- Issue #8622: Add PYTHONFSENCODING environment variable to override the
266 filesystem encoding.
267
Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +0000268- Issue #5127: The C functions that access the Unicode Database now accept and
269 return characters from the full Unicode range, even on narrow unicode builds
270 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
271 in Python is that unicodedata.numeric() now returns the correct value for
272 large code points, and repr() may consider more characters as printable.
273
Victor Stinner6c00c142010-08-17 23:37:11 +0000274- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
275 as a unicode object, instead of a byte string. Function needed to support
276 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
277 function.
278
Victor Stinner6961bd62010-08-17 22:26:51 +0000279- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

Antoine Pitrou671b4d92010-08-17 17:55:07 +0000281- Issue #9612: The set object is now 64-bit clean under Windows.
282
Georg Brandl649971e2010-09-05 17:06:50 +0000283- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
284 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +0000285
Georg Brandl649971e2010-09-05 17:06:50 +0000286- Issue #9599: Create PySys_FormatStdout() and PySys_FormatStderr() functions to
287 write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
Victor Stinner79766632010-08-16 17:36:42 +0000288 sys.stderr.
289
Victor Stinner47fcb5b2010-08-13 23:59:58 +0000290- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +0000291 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
292 objects are output as-is.
Victor Stinner47fcb5b2010-08-13 23:59:58 +0000293
Georg Brandl649971e2010-09-05 17:06:50 +0000294- Issue #9203: Computed gotos are now enabled by default on supported compilers
295 (which are detected by the configure script). They can still be disable
296 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +0000297
Georg Brandl649971e2010-09-05 17:06:50 +0000298- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
299 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +0000300
Georg Brandl649971e2010-09-05 17:06:50 +0000301- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an

642
Ezio Melotti57221d02010-07-01 07:32:02 +0000643- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +0000644 start byte and the continuation byte(s) are now considered invalid, instead of
645 the number of bytes specified by the start byte. E.g.:
646 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
647 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
648 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
649 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +0000651- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
652 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

Georg Brandl62069d32010-07-31 08:56:11 +0000663- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
664 dealing with unary minus applied to a constant. The removed code was mutating
665 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +0000666
Victor Stinner554f3f02010-06-16 23:33:54 +0000667- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +0000668 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +0000669 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +0000670 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +0000671
Victor Stinner25e8ec42010-06-25 00:02:38 +0000672- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
673 "w*" format instead. Add tests for "w*" format.
674
Victor Stinner06e49dd2010-06-13 18:21:50 +0000675- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +0000676 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +0000677 string formats.
678
Georg Brandl62069d32010-07-31 08:56:11 +0000679- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +0000680 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
681 location of the raised exception.
682
Victor Stinner313a1202010-06-11 23:56:51 +0000683- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
684 filenames and enable os.fsencode().
685
Benjamin Peterson285a6892010-06-22 19:21:52 +0000686- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
687
Georg Brandl62069d32010-07-31 08:56:11 +0000688- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
689 interpreter with characters outside the Basic Multilingual Plane (higher than
690 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +0000691
Georg Brandl62069d32010-07-31 08:56:11 +0000692- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
693 TypeError instead of giving a DeprecationWarning when a float is parsed using
694 the 'L' code (for long long). (All other integer codes already raise
695 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +0000696
Victor Stinner600d3be2010-06-10 12:00:55 +0000697- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
698 enable shortcuts for upper case encoding name. Add also a shortcut for
699 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
700
Georg Brandl62069d32010-07-31 08:56:11 +0000701- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
702 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000703
704- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +0000705 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000706 like bytearray.
707
Georg Brandl62069d32010-07-31 08:56:11 +0000708- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +0000709 used anymore and it was never documented.
710
Georg Brandl62069d32010-07-31 08:56:11 +0000711- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +0000713- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
714 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +0000715
Georg Brandl62069d32010-07-31 08:56:11 +0000716- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
717 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
718 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
719 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +0000720
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000721- Issue #8748: Fix two issues with comparisons between complex and integer
722 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +0000723 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
724 (2) The comparison raised an OverflowError for large integers, leading to
725 unpredictable exceptions when combining integers and complex objects in sets
726 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000727
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000728- Issue #8766: Initialize _warnings module before importing the first module.

730
Victor Stinner9ca9c252010-05-19 16:53:30 +0000731- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +0000732 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +0000733 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +0000734
Georg Brandl62069d32010-07-31 08:56:11 +0000735- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
736 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +0000737
Victor Stinnerae6265f2010-05-15 16:27:27 +0000738- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
739 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +0000740 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000741 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000742
Victor Stinner59e62db2010-05-15 13:14:32 +0000743- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +0000744 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +0000745
Victor Stinnerb744ba12010-05-15 12:27:16 +0000746- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +0000747 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +0000748 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
749
Victor Stinner0964ee12010-04-30 16:48:45 +0000750- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +0000751 PyUnicode_FromString() to support surrogates in the filename and use the right
752 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +0000753
Georg Brandl8569e582010-05-19 20:57:08 +0000754- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
755
Georg Brandl62069d32010-07-31 08:56:11 +0000756- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000757
Benjamin Petersonfb886362010-04-24 18:21:17 +0000758- Issue #8419: Prevent the dict constructor from accepting non-string keyword

Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000855- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +0000856 where the right hand operand is a set of constants, by turning the set into a
857 frozenset and pre-building it as a constant. The comparison operation is made
858 against the constant instead of building a new set each time it is executed (a
859 similar optimization already existed which turned a list of constants into a
860 pre-built tuple). Patch and additional tests by Dave Malcolm.

887 least on IEEE 754 platforms), and in particular does not depend on the
888 internal representation of an int.

916 long but the length of the range did not. Also fix several cases where

1030 `va_copy`, but available on all python platforms.
1031
Mark Dickinsone6fc7402010-08-06 18:55:26 +00001032- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
1033 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

1056 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
1057 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00001058 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00001068- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
1069 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
1070 accessing the d_type and d_name members of structures using PyDescr_COMMON.

1087 gives improved memory leak detection when running under Valgrind, while taking
1088 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00001163 simply clearing the entire cache on overflow to forgetting the least recently
1164 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00001165 applications that use a lot of regular expressions and limits the impact of
1166 the performance hit anytime the cache is exceeded.

1180 defined in datetime with fast C impementation. Python implementation is based
1181 on the original python prototype for the datetime module by Tim Peters with
1182 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00001580- Issue #2531: Comparison operations between floats and Decimal instances now
1581 return a result based on the numeric values of the operands; previously they
1582 returned an arbitrary result based on the relative ordering of id(float) and
1583 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
1584 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00001588- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00001589 argument `-` which tells it to read files to compile from stdin. Each line is

1598 Fractions instance now raise TypeError instead of returning True/False. This
1599 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1600 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00001647- subprocess.Popen now has restore_signals and start_new_session features. The
1648 default of restore_signals=True is a new behavior compared to earlier Python
1649 versions. This means that signals such as SIGPIPE are not ignored by default
1650 in subprocesses launched by Python (Issue #1652).

1744 a :class:`io.BufferedReader` object for more speedups. It also solves an
1745 issue where interleaved calls to `read()` and `readline()` give wrong results.

Georg Brandl62069d32010-07-31 08:56:11 +00002141 compared to other unix systems. In particular, os.getgroups() does not reflect

2175 directive. When the ``%z`` directive is present in the format string, an
2176 aware ``datetime`` object is returned with ``tzinfo`` bound to a
2177 ``datetime.timezone`` instance constructed from the parsed offset. If both
2178 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
2179 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00002181- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00002182 implementing ``datetime.tzinfo`` interface. Instances of the new class,
2183 ``datetime.timezone``, return fixed name and UTC offset from their
2184 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
2185 returns ``None``. A class attribute, ``utc`` contains an instance
2186 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00002213 the result is now always correctly rounded, and is equivalent to ``td /

Georg Brandl62069d32010-07-31 08:56:11 +00002511 runtest_inner in regrtest, with warnings if the called test modifies them, and

2683 (1) inf and nan strings with trailing whitespace were incorrectly
2684 rejected; (2) parsing of strings representing infinities and nans
2685 was locale aware; and (3) the interpretation of fromhex('-nan')
2686 didn't match that of float('-nan').

2789Core and Builtins
2790-----------------
2791
Mark Dickinson865e01a2009-05-07 16:37:01 +00002792- Issue #5914: Add new C API function PyOS_string_to_double, and
2793 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2794
Eric Smith741191f2009-05-06 13:08:15 +00002795- Issue #3382: float.__format__, complex.__format__, and %-formatting
2796 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2797 affects nan -> NAN and inf -> INF.
2798
Mark Hammond5a607a32009-05-06 08:04:54 +00002799- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2800 in all operations, including splitdrive, split, etc. splitunc() now issues
2801 a PendingDeprecation warning.
2802
Eric Smith63376222009-05-05 14:04:18 +00002803- Issue #5920: For float.__format__, change the behavior with the
2804 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2805 to be like 'g' but with at least one decimal point and with a
2806 default precision of 12. Previously, the behavior the same but with
2807 a default precision of 6. This more closely matches str(), and
2808 reduces surprises when adding alignment flags to the empty
2809 presentation type. This also affects the new complex.__format__ in
2810 the same way.
2811
Martin v. Löwis011e8422009-05-05 04:43:17 +00002812- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2813
R. David Murrayb18500d2009-05-04 22:59:07 +00002814- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2815 shadowed by classtype's, even if it was None. property now
2816 inserts the __doc__ into the subclass instance __dict__.
2817
Antoine Pitrou244651a2009-05-04 18:56:13 +00002818- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2819 sequences. Patch by Nick Barnes and Victor Stinner.
2820
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002821- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002822
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002823- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2824 received a new method, detach(). detach() disconnects the underlying stream
2825 from the buffer or text IO and returns it.
2826
Mark Dickinson33841c32009-05-01 15:37:04 +00002827- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2828 floats with absolute value over 1e50. Also remove length
2829 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2830 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002831
Eric Smith741191f2009-05-06 13:08:15 +00002832- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002833 format(complex(1, 2./3), '.5') now produces a sensible result.
2834
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002835- Issue #5864: Fix empty format code formatting for floats so that it
2836 never gives more than the requested number of significant digits.
2837
Eric Smith6dc46f52009-04-27 20:39:49 +00002838- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2839 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2840
Eric Smithcc32a112009-04-26 21:35:14 +00002841- Issue #5835: Deprecate PyOS_ascii_formatd.
2842
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002843- Issue #4971: Fix titlecase for characters that are their own
2844 titlecase, but not their own uppercase.
2845
Benjamin Peterson193152c2009-04-25 01:08:45 +00002846- Issue #5283: Setting __class__ in __del__ caused a segfault.
2847
Mark Dickinsonad476da2009-04-23 19:14:16 +00002848- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2849 z involves nans, infs or negative zeros.
2850
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002851- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002852
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002853- Issue #1869 (and many duplicates): make round(x, n) correctly
2854 rounded for a float x, by using the decimal <-> binary conversions
2855 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2856 consistently agrees with format(x, '.2f').
2857
Benjamin Petersonae937c02009-04-18 20:54:08 +00002858- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2859 some builtin types.
2860
Eric Smith0923d1d2009-04-16 20:16:10 +00002861- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2862
Eric Smith35e84722009-04-16 20:21:28 +00002863- Issue #5515: str.format() type 'n' combined with commas and leading
2864 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002865
2866- Implement PEP 378, Format Specifier for Thousands Separator, for
2867 floats.
2868
Mark Dickinson3370cce2009-04-17 22:40:53 +00002869- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002870 1e11, not 1e12. This avoids printing 13 significant digits in
2871 situations where only 12 of them are correct. Example problem
2872 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2873 long time.)
2874
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002875- Issue #1580: On most platforms, use a 'short' float repr: for a
2876 finite float x, repr(x) now outputs a string based on the shortest
2877 sequence of decimal digits that rounds to x. Previous behaviour was
2878 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002879 Another minor difference is that the new repr switches to
2880 exponential notation at 1e16 instead of the previous 1e17; this
2881 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002882
2883 There's a new sys attribute sys.float_repr_style, which takes
2884 the value 'short' to indicate that we're using short float repr,
2885 and 'legacy' if the short float repr isn't available for one
2886 reason or another.
2887
2888 The float repr change involves incorporating David Gay's 'perfect
2889 rounding' code into the Python core (it's in Python/dtoa.c). As a
2890 secondary consequence, all string-to-float and float-to-string
2891 conversions (including all float formatting operations) will be
2892 correctly rounded on these platforms.
2893
Georg Brandl5f90d792010-08-01 22:31:05 +00002894 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002895 this change does not apply.
2896
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002897- Issue #5759: float() didn't call __float__ on str subclasses.
2898
Georg Brandlabc38772009-04-12 15:51:51 +00002899- The string.maketrans() function is deprecated; there is a new static method
2900 maketrans() on the bytes and bytearray classes. This removes confusion about
2901 the types string.maketrans() is supposed to work with, and mirrors the
2902 methods available on the str class.
2903
R. David Murraydc6da8a2009-04-09 22:16:43 +00002904- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2905 its clarity and its speed.
2906
Georg Brandl65ce6ad2010-09-05 17:32:31 +00002907- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00002908 to avoid compiler warnings.
2909
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002910- Issue #3739: The unicode-internal encoder now reports the number of characters
2911 consumed like any other encoder (instead of the number of bytes).

3249 common cases are optimized thanks to a dedicated fast path and a moderate
3250 amount of loop unrolling.
3251
Antoine Pitrou14b78f52009-01-09 22:27:08 +00003252- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
3253 collecting the oldest generation) so that allocating lots of objects without
3254 destroying them does not show quadratic performance. Based on a proposal by
3255 Martin von Löwis at
3256 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
3257
Vinay Sajip6268cbc2009-01-21 00:19:28 +00003258- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00003259 having been closed (for instance, a read() call could return some
3260 previously buffered data). Patch by Dmitry Vasiliev.
3261
Antoine Pitrou05608432009-01-09 18:53:14 +00003262- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
3263 flag to work properly. Furthermore, when specifying -u, the text stdout
3264 and stderr streams have line-by-line buffering enabled (the default being
3265 to buffer arbitrary chunks of data).
3266
Raymond Hettinger35631532009-01-09 03:58:09 +00003267- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
3268 instead of ints (reducing its size from 4 to 8 times thereby reducing
3269 Python's overall memory).
3270
Antoine Pitroud35cbf62009-01-06 19:02:24 +00003271- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
3272 an existing .py counterpart, override the co_filename attributes of all
3273 code objects if the original filename is obsolete (which can happen if the
3274 file has been renamed, moved, or if it is accessed through different paths).
3275 Patch by Ziga Seilnacht and Jean-Paul Calderone.
3276
Antoine Pitrouc3b39242009-01-03 16:59:18 +00003277- Issue #4580: Fix slicing of memoryviews when the item size is greater than
3278 one byte. Also fixes the meaning of len() so that it returns the number of
3279 items, rather than the size in bytes.
3280
Martin v. Löwis5c88d812009-01-02 20:47:48 +00003281- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00003283- Issue #4747: When the terminal does not use utf-8, executing a script with
3284 non-ascii characters in its name could fail with a "SyntaxError: None" error.
3285
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003286- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

Antoine Pitrou7ddda782009-01-01 15:35:33 +00003289- Issue #3680: Reference cycles created through a dict, set or deque iterator
3290 did not get collected.
3291
Nick Coghlanf1f2f682008-12-30 07:29:12 +00003292- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
3293 where the tp_hash and tp_dict slots are both NULL.
3294
Georg Brandlccc47b62008-12-28 11:44:14 +00003295- Issue #4759: None is now allowed as the first argument of
3296 bytearray.translate(). It was always allowed for bytes.translate().
3297
Skip Montanaro80072cb2008-12-23 03:51:14 +00003298- Added test case to ensure attempts to read from a file opened for writing
3299 fail.

3305
Antoine Pitrou621601a2008-12-17 23:18:19 +00003306- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

3314 failures on OS X.
3315
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00003316- Issue #4597: Fixed several opcodes that weren't always propagating
3317 exceptions.
3318
3319- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00003320 context manager returns a value that cannot be converted to a bool.
3321
Mark Dickinsonfd24b322008-12-06 15:33:31 +00003322- Issue #4445: Replace "sizeof(PyBytesObject)" with
3323 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
3324 bytes instances. On a typical machine this saves 3 bytes of memory
3325 (on average) per allocation of a bytes instance.
3326
Christian Heimesa872de52008-12-05 08:26:55 +00003327- Issue #4533: File read operation was dreadfully slow due to a slowly
3328 growing read buffer. Fixed by using the same growth rate algorithm as
3329 Python 2.x.
3330
Antoine Pitrou5504e892008-12-06 21:27:53 +00003331- Issue #4509: Various issues surrounding resize of bytearray objects to
3332 which there are buffer exports (e.g. memoryview instances).
3333
Georg Brandlf9734072008-12-07 15:30:06 +00003334- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
3335 method on file objects with closefd=False. The file descriptor is still
3336 kept open but the file object behaves like a closed file. The ``FileIO``
3337 object also got a new readonly attribute ``closefd``.

3345
Walter Dörwaldc1651a02009-05-03 22:55:55 +00003346- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
3347 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3348 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3349 of using the replace error handler in PyUnicode_DecodeUTF8().
