Benjamin Peterson46ea4f72009-06-27 21:40:27 +00007What's New in Python 3.2 Alpha 1?
8=================================
9
10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Antoine Pitrou05b7c562010-02-02 22:47:00 +000015- Issue #7385: Fix a crash in `MemoryView_FromObject` when
16 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
17
Mark Dickinsonbc099642010-01-29 17:27:24 +000018- Issue #7788: Fix an interpreter crash produced by deleting a list
19 slice with very large step value.
20
Eric Smithf7bb5782010-01-27 00:44:57 +000021- Issue #7766: Change sys.getwindowsversion() return value to a named
22 tuple and add the additional members returned in an OSVERSIONINFOEX
23 structure. The new members are service_pack_major, service_pack_minor,
24 suite_mask, and product_type.
25
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000026- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
27 could crash in many places because of the PyByteArray_AS_STRING() macro
28 returning NULL. The macro now returns a statically allocated empty
29 string instead.
30
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000031- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
32 where the right hand operand is a set of constants, by turning the set into
33 a frozenset and pre-building it as a constant. The comparison operation
34 is made against the constant instead of building a new set each time it is
35 executed (a similar optimization already existed which turned a list of
36 constants into a pre-built tuple). Patch and additional tests by Dave
37 Malcolm.
38
Antoine Pitrouf2c54842010-01-13 08:07:53 +000039- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
40 methods of bytes, bytearray and unicode objects by using a common
41 implementation based on stringlib's fast search. Patch by Florent Xicluna.
42
Mark Dickinson45b63652010-01-16 18:10:25 +000043- Issue #7632: Fix various str -> float conversion bugs present in 2.7
44 alpha 2, including: (1) a serious 'wrong output' bug that could
45 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
46 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000047 strings corresponding to subnormal values, (3) a memory leak for
48 some values large enough to cause overflow, and (4) a number of
49 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000050
Benjamin Petersonaea44282010-01-04 01:10:28 +000051- The __complex__ method is now looked up on the class of instances to make it
52 consistent with other special methods.
53
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000054- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
55 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
56
Benjamin Petersond12362a2009-12-30 19:44:54 +000057- Issue #7604: Deleting an unset slotted attribute did not raise an
58 AttributeError.
59
Mark Dickinson9ab44b52009-12-30 16:22:49 +000060- Issue #7534: Fix handling of IEEE specials (infinities, nans,
61 negative zero) in ** operator. The behaviour now conforms to that
62 described in C99 Annex F.
63
Mark Dickinsoncbb62742009-12-27 15:09:50 +000064- Issue #1811: improve accuracy and cross-platform consistency for
65 true division of integers: the result of a/b is now correctly
66 rounded for ints a and b (at least on IEEE 754 platforms), and in
67 particular does not depend on the internal representation of an int.
68
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000069- Issue #6834: replace the implementation for the 'python' and 'pythonw'
70 executables on OSX.
71
72 These executables now work properly with the arch(1) command:
73 ``arch -ppc python`` will start a universal binary version of python
74 in PPC mode (unlike previous releases).
75
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000076- Issue #7466: segmentation fault when the garbage collector is called
77 in the middle of populating a tuple. Patch by Florent Xicluna.
78
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +000079- Issue #7419: setlocale() could crash the interpreter on Windows when called
80 with invalid values.
81
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +000082- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
83 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
84
Ronald Oussoren3c1928a2009-11-19 17:15:31 +000085- Issue #7085: Fix crash when importing some extensions in a thread
86 on MacOSX 10.6.
87
Philip Jenvey1309adb2009-11-17 03:43:14 +000088- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
89
Mark Dickinson6f1d0492009-11-15 13:58:49 +000090- Issue #6970: Remove redundant calls when comparing objects that don't
91 implement the relevant rich comparison methods.
92
Mark Dickinsond550c9a2009-11-15 09:57:26 +000093- Issue #7298: fixes for range and reversed(range(...)). Iteration
94 over range(a, b, c) incorrectly gave an empty iterator when a, b and
95 c fit in C long but the length of the range did not. Also fix
96 several cases where reversed(range(a, b, c)) gave wrong results, and
97 fix a refleak for reversed(range(a, b, c)) with large arguments.
98
Raymond Hettingerfc438512009-11-01 20:55:33 +000099- Issue #7244: itertools.izip_longest() no longer ignores exceptions
100 raised during the formation of an output tuple.
101
Benjamin Petersonb2e796a2009-10-28 21:59:39 +0000102- Issue #3297: On wide unicode builds, do not split unicode characters into
103 surrogates.

108
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000109- Support for AtheOS has been completely removed from the code base. It was
110 disabled since Python 3.0.
111
112- Support for several legacy threading libraries has been disabled. These
113 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
114 will be entirely removed in 3.3.
115
Raymond Hettingeraf7adad2009-10-22 11:22:50 +0000116- Peephole constant folding had missed UNARY_POSITIVE.
117
Antoine Pitrou011bd622009-10-20 21:52:47 +0000118- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
119 fixes the problem of some exceptions being thrown at shutdown when the
120 interpreter is killed. Patch by Adam Olsen.
121

126 crash in GAE.
127
Neil Schemenauere441cb72009-10-14 19:14:38 +0000128- Issue #1754094: Improve the stack depth calculation in the compiler.
129 There should be no other effect than a small decrease in memory use.
130 Patch by Christopher Tur Lesniewski-Laas.
131
Antoine Pitrou403ce782009-10-14 17:14:16 +0000132- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when
Antoine Pitrou671141d2009-10-19 19:37:25 +0000133 using byte values greater than 127. Patch by Derk Drukker.
Antoine Pitrou403ce782009-10-14 17:14:16 +0000134
Amaury Forgeot d'Arc7d520792009-10-06 21:03:20 +0000135- Issue #1571184: The Unicode database contains properties for more characters.
136 The tables for code points representing numeric values, white spaces or line
137 breaks are now generated from the official Unicode Character Database files,
138 and include information from the Unihan.txt file.
139
Mark Dickinson2683ab02009-09-29 19:21:35 +0000140- Issue #7019: Raise ValueError when unmarshalling bad long data, instead
141 of producing internally inconsistent Python longs.
142
Philip Jenvey26713ca2009-09-29 04:57:18 +0000143- Issue #6990: Fix threading.local subclasses leaving old state around
144 after a reference cycle GC which could be recycled by new locals.

160
Raymond Hettingere805ecc2009-07-27 20:16:37 +0000161- Issue #6573: set.union() stopped processing inputs if an instance of self
162 occurred in the argument chain.
163
R. David Murray046f7232009-07-19 02:22:05 +0000164- Issue #6070: On posix platforms import no longer copies the execute bit

171 documentation.
172
Benjamin Petersonf1664ae2009-07-01 01:28:55 +0000173- The deprecated PyCObject has been removed.
174
Mark Dickinson835a6c82009-06-30 15:45:17 +0000175- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
176 This fixes a build failure on HP-UX: int32_t and uint32_t are
177 defined in inttypes.h instead of stdint.h on that platform.
178
Amaury Forgeot d'Arca4aba662009-07-01 00:48:39 +0000179- Issue #6373: Fixed a SystemError when encoding with the latin-1 codec and

197
Mark Dickinson93f562c2010-01-30 10:30:15 +0000198- Issue #7767: New function PyLong_AsLongLongAndOverflow added,
199 analogous to PyLong_AsLongAndOverflow.
200
Benjamin Peterson8667a9b2010-01-09 21:45:28 +0000201- Make PyUnicode_CompareWithASCIIString return not equal if the Python string

207 DeprecationWarning for float arguments passed with the 'L' format
208 code. This will become a TypeError in a future version of Python,
209 to match the behaviour of the other integer format codes.
210

220 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
221 should used for accessing the d_type and d_name members of structures
222 using PyDescr_COMMON.
223
224- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000225

232 object at a specified file, function, and line number.
233
234- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
235 ``const char *`` as the string is stored beyond the call.
236
Benjamin Peterson05159c42009-12-03 03:01:27 +0000237- Issue #2422: When compiled with the ``--with-valgrind`` option, the
238 pymalloc allocator will be automatically disabled when running under
239 Valgrind. This gives improved memory leak detection when running
240 under Valgrind, while taking advantage of pymalloc at other times.

249 exception of canonical and is_canonical) now accept instances of int
250 and long wherever a Decimal instance is accepted, and implicitly
251 convert that argument to Decimal. Previously only some arguments
252 were converted.
253
R. David Murray1f449142010-02-11 00:15:05 +0000254- Issue #7835: shelve should no longer produce mysterious warnings during
255 interpreter shutdown.
256
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000257- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
258 in XML processing instructions and comments. These raw characters are
259 allowed by the XML specification, and are necessary when outputting e.g.
260 PHP code in a processing instruction. Patch by Neil Muller.
261
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000262- Issue #6233: ElementTree failed converting unicode characters to XML

264 encoding. Patch by Jerry Chen.
265
Ronald Oussorenee5c8852010-02-07 20:24:02 +0000266- Issue #6003: add an argument to ``zipfile.Zipfile.writestr`` to
267 specify the compression type.
268
Antoine Pitroub6375f12010-02-04 20:23:24 +0000269- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is

272 type is specified. Patch by Brian Curtin.
273
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000274- Issue #6939: Fix file I/O objects in the `io` module to keep the original
275 file position when calling `truncate()`. It would previously change the
276 file position to the given argument, which goes against the tradition of
277 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
278
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000279- Issue #7610: Reworked implementation of the internal
280 :class:`zipfile.ZipExtFile` class used to represent files stored inside
281 an archive. The new implementation is significantly faster and can
282 be wrapped in a :class:`io.BufferedReader` object for more speedups.
283 It also solves an issue where interleaved calls to `read()` and
284 `readline()` give wrong results. Patch by Nir Aides.
285
Jesse Noller1f0b6582010-01-27 03:36:01 +0000286- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
287 allowing for a maximum number of tasks within the pool to be completed by
288 the worker before that worker is terminated, and a new one created to
289 replace it.

631
Brett Cannon64ef00f2009-07-20 03:19:18 +0000632- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
633 the documentation said it did even though the code in PyLoader relied on the
634 abstract method required by ResourceLoader.

788 to empty global variables.
789
Antoine Pitrou941ee882009-11-11 20:59:38 +0000790- Issue #7295: Do not use a hardcoded file name in test_tarfile.

804 leak-chasing test runs give sensible results. The previous method of
805 reaping threads could return successfully while some Thread objects were
806 still referenced. This also introduces a new private function:
807 :func:`_thread._count()`.
808
R. David Murray27144602009-10-19 15:26:16 +0000809- Issue #7151: fixed regrtest -j so that output to stderr from a test no
810 longer runs the risk of causing the worker thread to fail.
811
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000812- Issue #7055: test___all__ now greedily detects all modules which have an
813 __all__ attribute, rather than using a hardcoded and incomplete list.

Mark Dickinson2e304402009-10-04 18:43:54 +0000819- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
820
Brett Cannon3c273842009-07-20 00:14:29 +0000821- Fixed tests in importlib.test.source.test_abc_loader that were masking

961Core and Builtins
962-----------------
963
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000964- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
965 of the command line.
966

Eric Smith41669ca2009-05-23 14:23:22 +0000969- Issue #6089: Fixed str.format with certain invalid field specifiers
970 that would raise SystemError.
971
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000972- Issue #5982: staticmethod and classmethod now expose the wrapped
973 function with __func__.
974
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000975- Added support for multiple context managers in the same with-statement.
976 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000978- Issue #5829: complex("1e500") no longer raises OverflowError. This
979 makes it consistent with float("1e500") and interpretation of real
980 and imaginary literals.
981
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000982- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
983
R. David Murraydd226ea2009-05-13 12:27:21 +0000984- Issue #5994: the marshal module now has docstrings.
985
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000986- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
987 (1) inf and nan strings with trailing whitespace were incorrectly
988 rejected; (2) parsing of strings representing infinities and nans
989 was locale aware; and (3) the interpretation of fromhex('-nan')
990 didn't match that of float('-nan').

993-------
994
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000995- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
996

998
R. David Murray1f1b9d32009-05-27 20:56:59 +0000999- Issue #6121: pydoc now ignores leading and trailing spaces in the
1000 argument to the 'help' function.
1001
Georg Brandlfaf41492009-05-26 18:31:11 +00001002- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1003 arguments for strings with a space in them.
1004
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001005- collections.namedtuple() was not working with the following field
1006 names: cls, self, tuple, itemgetter, and property.
1007
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001008- In unittest, using a skipping decorator on a class is now equivalent to
1009 skipping every test on the class. The ClassTestSuite class has been removed.
1010
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001011- Issue #6050: Don't fail extracting a directory from a zipfile if
1012 the directory already exists.
1013
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001014- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1015 than an int, which makes some operations possible under 64-bit Linux (e.g.
1016 DN_MULTISHOT with F_NOTIFY).
1017
Antoine Pitrou716c4442009-05-23 19:04:03 +00001018- Issue #5761: Add the name of the underlying file to the repr() of various
1019 IO objects.
1020
R. David Murraycaa27b72009-05-23 18:49:56 +00001021- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1022 by Musashi Tamura, tests by Marcin Bachry.
1023
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001024- Issue #1983: Fix functions taking or returning a process identifier to use
1025 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1026 a process identifier type wider than the standard C integer type.
1027
R. David Murray87e20742009-05-23 01:30:26 +00001028- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1039
Antoine Pitroue4501852009-05-14 18:55:55 +00001040- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1041 library. This means, for example, that opening an UTF-16 text file in
1042 append mode doesn't add a BOM at the end of the file if the file isn't
1043 empty.
1044
R. David Murray74b89242009-05-13 17:33:03 +00001045- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1046 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1047 corrects a pydoc regression.
1048
R. David Murray99352742009-05-07 18:24:38 +00001049- Issue 5955: aifc's close method did not close the file it wrapped,
1050 now it does. This also means getfp method now returns the real fp.
1051
Benjamin Peterson932073a2009-05-23 16:14:33 +00001052Installation
1053------------
1054
1055- Issue #6047: fullinstall has been removed because Python 3's executable will
1056 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001057

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001092
1093Core and Builtins
1094-----------------
1095
Mark Dickinson865e01a2009-05-07 16:37:01 +00001096- Issue #5914: Add new C API function PyOS_string_to_double, and
1097 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1098
Eric Smith741191f2009-05-06 13:08:15 +00001099- Issue #3382: float.__format__, complex.__format__, and %-formatting
1100 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1101 affects nan -> NAN and inf -> INF.
1102
Mark Hammond5a607a32009-05-06 08:04:54 +00001103- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1104 in all operations, including splitdrive, split, etc. splitunc() now issues
1105 a PendingDeprecation warning.
1106
Eric Smith63376222009-05-05 14:04:18 +00001107- Issue #5920: For float.__format__, change the behavior with the
1108 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1109 to be like 'g' but with at least one decimal point and with a
1110 default precision of 12. Previously, the behavior the same but with
1111 a default precision of 6. This more closely matches str(), and
1112 reduces surprises when adding alignment flags to the empty
1113 presentation type. This also affects the new complex.__format__ in
1114 the same way.
1115
Martin v. Löwis011e8422009-05-05 04:43:17 +00001116- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1117
R. David Murrayb18500d2009-05-04 22:59:07 +00001118- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1119 shadowed by classtype's, even if it was None. property now
1120 inserts the __doc__ into the subclass instance __dict__.
1121
Antoine Pitrou244651a2009-05-04 18:56:13 +00001122- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1123 sequences. Patch by Nick Barnes and Victor Stinner.
1124
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001125- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001126
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001127- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1128 received a new method, detach(). detach() disconnects the underlying stream
1129 from the buffer or text IO and returns it.
1130
Mark Dickinson33841c32009-05-01 15:37:04 +00001131- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1132 floats with absolute value over 1e50. Also remove length
1133 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1134 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001135
Eric Smith741191f2009-05-06 13:08:15 +00001136- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001137 format(complex(1, 2./3), '.5') now produces a sensible result.
1138
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001139- Issue #5864: Fix empty format code formatting for floats so that it
1140 never gives more than the requested number of significant digits.
1141
Eric Smith6dc46f52009-04-27 20:39:49 +00001142- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1143 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1144
Eric Smithcc32a112009-04-26 21:35:14 +00001145- Issue #5835: Deprecate PyOS_ascii_formatd.
1146
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001147- Issue #4971: Fix titlecase for characters that are their own
1148 titlecase, but not their own uppercase.
1149
Benjamin Peterson193152c2009-04-25 01:08:45 +00001150- Issue #5283: Setting __class__ in __del__ caused a segfault.
1151
Mark Dickinsonad476da2009-04-23 19:14:16 +00001152- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1153 z involves nans, infs or negative zeros.
1154
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001155- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001156
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001157- Issue #1869 (and many duplicates): make round(x, n) correctly
1158 rounded for a float x, by using the decimal <-> binary conversions
1159 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1160 consistently agrees with format(x, '.2f').
1161
Benjamin Petersonae937c02009-04-18 20:54:08 +00001162- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1163 some builtin types.
1164
Eric Smith0923d1d2009-04-16 20:16:10 +00001165- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1166
Eric Smith35e84722009-04-16 20:21:28 +00001167- Issue #5515: str.format() type 'n' combined with commas and leading
1168 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001169
1170- Implement PEP 378, Format Specifier for Thousands Separator, for
1171 floats.
1172
Mark Dickinson3370cce2009-04-17 22:40:53 +00001173- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001174 1e11, not 1e12. This avoids printing 13 significant digits in
1175 situations where only 12 of them are correct. Example problem
1176 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1177 long time.)
1178
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001179- Issue #1580: On most platforms, use a 'short' float repr: for a
1180 finite float x, repr(x) now outputs a string based on the shortest
1181 sequence of decimal digits that rounds to x. Previous behaviour was
1182 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001183 Another minor difference is that the new repr switches to
1184 exponential notation at 1e16 instead of the previous 1e17; this
1185 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001186
1187 There's a new sys attribute sys.float_repr_style, which takes
1188 the value 'short' to indicate that we're using short float repr,
1189 and 'legacy' if the short float repr isn't available for one
1190 reason or another.
1191
1192 The float repr change involves incorporating David Gay's 'perfect
1193 rounding' code into the Python core (it's in Python/dtoa.c). As a
1194 secondary consequence, all string-to-float and float-to-string
1195 conversions (including all float formatting operations) will be
1196 correctly rounded on these platforms.
1197
1198 See issue 1580 discussions for details of platforms for which
1199 this change does not apply.
1200
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001201- Issue #5759: float() didn't call __float__ on str subclasses.
1202
Georg Brandlabc38772009-04-12 15:51:51 +00001203- The string.maketrans() function is deprecated; there is a new static method
1204 maketrans() on the bytes and bytearray classes. This removes confusion about
1205 the types string.maketrans() is supposed to work with, and mirrors the
1206 methods available on the str class.
1207
R. David Murraydc6da8a2009-04-09 22:16:43 +00001208- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1209 its clarity and its speed.
1210
Matthias Klose091c7b12009-04-07 13:24:27 +00001211- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1212 to avoid compiler warnings.
1213
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001214- Issue #3739: The unicode-internal encoder now reports the number of characters
1215 consumed like any other encoder (instead of the number of bytes).
1216

1515 Previously it returned a float.
1516
Antoine Pitroub52ec782009-01-25 16:34:23 +00001517- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1518 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1519 evaluation loop is compiled with a new dispatch mechanism which gives
1520 speedups of up to 20%, depending on the system, on various benchmarks.
1521
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001522- Issue #4874: Most builtin decoders now reject unicode input.

1528
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001529- Issue #4838: When a module is deallocated, free the memory backing the
1530 optional module state data.
1531
Mark Dickinson8055afd2009-01-17 10:04:45 +00001532- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1533 type to (void *).
1534
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001535- Issue #4935: The overflow checking code in the expandtabs() method common
1536 to str, bytes and bytearray could be optimized away by the compiler, letting
1537 the interpreter segfault instead of raising an error.
1538
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001539- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1540 __next__ method.
1541
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001542- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1543 function no longer attempt to call the __long__ slot to convert an object
1544 to an integer. Only the __int__ and __trunc__ slots are examined.

1549
Antoine Pitrouab868312009-01-10 15:40:25 +00001550- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1551 common cases are optimized thanks to a dedicated fast path and a moderate
1552 amount of loop unrolling.
1553
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001554- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1555 collecting the oldest generation) so that allocating lots of objects without
1556 destroying them does not show quadratic performance. Based on a proposal by
1557 Martin von Löwis at
1558 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1559
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001560- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001561 having been closed (for instance, a read() call could return some
1562 previously buffered data). Patch by Dmitry Vasiliev.
1563
Antoine Pitrou05608432009-01-09 18:53:14 +00001564- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1565 flag to work properly. Furthermore, when specifying -u, the text stdout
1566 and stderr streams have line-by-line buffering enabled (the default being
1567 to buffer arbitrary chunks of data).
1568
Raymond Hettinger35631532009-01-09 03:58:09 +00001569- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1570 instead of ints (reducing its size from 4 to 8 times thereby reducing
1571 Python's overall memory).
1572
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001573- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1574 an existing .py counterpart, override the co_filename attributes of all
1575 code objects if the original filename is obsolete (which can happen if the
1576 file has been renamed, moved, or if it is accessed through different paths).
1577 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1578
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001579- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1580 one byte. Also fixes the meaning of len() so that it returns the number of
1581 items, rather than the size in bytes.
1582
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001583- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1584
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001585- Issue #4747: When the terminal does not use utf-8, executing a script with
1586 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1587
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001588- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1592 did not get collected.
1593
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001594- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1595 where the tp_hash and tp_dict slots are both NULL.
1596
Georg Brandlccc47b62008-12-28 11:44:14 +00001597- Issue #4759: None is now allowed as the first argument of
1598 bytearray.translate(). It was always allowed for bytes.translate().
1599
Skip Montanaro80072cb2008-12-23 03:51:14 +00001600- Added test case to ensure attempts to read from a file opened for writing
1601 fail.
1602

1607
Antoine Pitrou621601a2008-12-17 23:18:19 +00001608- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1610 unreachable. Original patch by Neil Schemenauer.
1611

1613
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001614- Issue #2173: When getting device encoding, check that return value of
1615 nl_langinfo is not the empty string. This was causing silent build
1616 failures on OS X.
1617
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001618- Issue #4597: Fixed several opcodes that weren't always propagating
1619 exceptions.
1620
1621- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001622 context manager returns a value that cannot be converted to a bool.
1623
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001624- Issue #4445: Replace "sizeof(PyBytesObject)" with
1625 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1626 bytes instances. On a typical machine this saves 3 bytes of memory
1627 (on average) per allocation of a bytes instance.
1628
Christian Heimesa872de52008-12-05 08:26:55 +00001629- Issue #4533: File read operation was dreadfully slow due to a slowly
1630 growing read buffer. Fixed by using the same growth rate algorithm as
1631 Python 2.x.
1632
Antoine Pitrou5504e892008-12-06 21:27:53 +00001633- Issue #4509: Various issues surrounding resize of bytearray objects to
1634 which there are buffer exports (e.g. memoryview instances).
1635
Georg Brandlf9734072008-12-07 15:30:06 +00001636- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1637 method on file objects with closefd=False. The file descriptor is still
1638 kept open but the file object behaves like a closed file. The ``FileIO``
1639 object also got a new readonly attribute ``closefd``.

1647
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001648- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1649 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1650 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1651 of using the replace error handler in PyUnicode_DecodeUTF8().
