Mark Dickinson6b1e43b2009-05-20 18:41:04 +000047- Issue #5829: complex("1e500") no longer raises OverflowError. This
48 makes it consistent with float("1e500") and interpretation of real
49 and imaginary literals.
50
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +000051- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

54
Mark Dickinsond1ec8b22009-05-11 15:45:15 +000055- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
56 (1) inf and nan strings with trailing whitespace were incorrectly
57 rejected; (2) parsing of strings representing infinities and nans
58 was locale aware; and (3) the interpretation of fromhex('-nan')
59 didn't match that of float('-nan').

72 arguments for strings with a space in them.
73
Raymond Hettinger089ba7f2009-05-27 00:38:24 +000074- collections.namedtuple() was not working with the following field
75 names: cls, self, tuple, itemgetter, and property.
76
Benjamin Peterson14a3dd72009-05-25 00:51:58 +000077- In unittest, using a skipping decorator on a class is now equivalent to
78 skipping every test on the class. The ClassTestSuite class has been removed.
79
Martin v. Löwis70ccd162009-05-24 19:47:22 +000080- Issue #6050: Don't fail extracting a directory from a zipfile if
81 the directory already exists.
82
Antoine Pitrou61f77b52009-05-24 15:46:13 +000083- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
84 than an int, which makes some operations possible under 64-bit Linux (e.g.
85 DN_MULTISHOT with F_NOTIFY).
86
Antoine Pitrou716c4442009-05-23 19:04:03 +000087- Issue #5761: Add the name of the underlying file to the repr() of various

92
Antoine Pitrouc3ee1662009-05-23 16:02:33 +000093- Issue #1983: Fix functions taking or returning a process identifier to use
94 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
95 a process identifier type wider than the standard C integer type.
96
R. David Murray87e20742009-05-23 01:30:26 +000097- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

108
Antoine Pitroue4501852009-05-14 18:55:55 +0000109- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
110 library. This means, for example, that opening an UTF-16 text file in
111 append mode doesn't add a BOM at the end of the file if the file isn't
112 empty.
113
R. David Murray74b89242009-05-13 17:33:03 +0000114- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
115 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
116 corrects a pydoc regression.
117
R. David Murray99352742009-05-07 18:24:38 +0000118- Issue 5955: aifc's close method did not close the file it wrapped,
119 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000157What's New in Python 3.1 beta 1?
158================================
159
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000160*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000161
162Core and Builtins
163-----------------
164
Mark Dickinson865e01a2009-05-07 16:37:01 +0000165- Issue #5914: Add new C API function PyOS_string_to_double, and
166 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
167
Eric Smith741191f2009-05-06 13:08:15 +0000168- Issue #3382: float.__format__, complex.__format__, and %-formatting
169 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
170 affects nan -> NAN and inf -> INF.
171
Mark Hammond5a607a32009-05-06 08:04:54 +0000172- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
173 in all operations, including splitdrive, split, etc. splitunc() now issues
174 a PendingDeprecation warning.
175
Eric Smith63376222009-05-05 14:04:18 +0000176- Issue #5920: For float.__format__, change the behavior with the
177 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
178 to be like 'g' but with at least one decimal point and with a
179 default precision of 12. Previously, the behavior the same but with
180 a default precision of 6. This more closely matches str(), and
181 reduces surprises when adding alignment flags to the empty
182 presentation type. This also affects the new complex.__format__ in
183 the same way.
184
Martin v. Löwis011e8422009-05-05 04:43:17 +0000185- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
186
R. David Murrayb18500d2009-05-04 22:59:07 +0000187- Issue #5890: in subclasses of 'property' the __doc__ attribute was
188 shadowed by classtype's, even if it was None. property now
189 inserts the __doc__ into the subclass instance __dict__.
190
Antoine Pitrou244651a2009-05-04 18:56:13 +0000191- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
192 sequences. Patch by Nick Barnes and Victor Stinner.
193
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000194- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000195
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000196- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
197 received a new method, detach(). detach() disconnects the underlying stream
198 from the buffer or text IO and returns it.
199
Mark Dickinson33841c32009-05-01 15:37:04 +0000200- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
201 floats with absolute value over 1e50. Also remove length
202 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
203 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000204
Eric Smith741191f2009-05-06 13:08:15 +0000205- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000206 format(complex(1, 2./3), '.5') now produces a sensible result.
207
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000208- Issue #5864: Fix empty format code formatting for floats so that it
209 never gives more than the requested number of significant digits.
210
Eric Smith6dc46f52009-04-27 20:39:49 +0000211- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
212 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
213
Eric Smithcc32a112009-04-26 21:35:14 +0000214- Issue #5835: Deprecate PyOS_ascii_formatd.
215
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000216- Issue #4971: Fix titlecase for characters that are their own
217 titlecase, but not their own uppercase.
218
Benjamin Peterson193152c2009-04-25 01:08:45 +0000219- Issue #5283: Setting __class__ in __del__ caused a segfault.
220
Mark Dickinsonad476da2009-04-23 19:14:16 +0000221- Issue #5816: complex(repr(z)) now recovers z exactly, even when
222 z involves nans, infs or negative zeros.
223
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000224- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000225
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000226- Issue #1869 (and many duplicates): make round(x, n) correctly
227 rounded for a float x, by using the decimal <-> binary conversions
228 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
229 consistently agrees with format(x, '.2f').
230
Benjamin Petersonae937c02009-04-18 20:54:08 +0000231- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
232 some builtin types.
233
Eric Smith0923d1d2009-04-16 20:16:10 +0000234- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
235
Eric Smith35e84722009-04-16 20:21:28 +0000236- Issue #5515: str.format() type 'n' combined with commas and leading
237 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000238
239- Implement PEP 378, Format Specifier for Thousands Separator, for
240 floats.
241
Mark Dickinson3370cce2009-04-17 22:40:53 +0000242- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000243 1e11, not 1e12. This avoids printing 13 significant digits in
244 situations where only 12 of them are correct. Example problem
245 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
246 long time.)
247
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000248- Issue #1580: On most platforms, use a 'short' float repr: for a
249 finite float x, repr(x) now outputs a string based on the shortest
250 sequence of decimal digits that rounds to x. Previous behaviour was
251 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000252 Another minor difference is that the new repr switches to
253 exponential notation at 1e16 instead of the previous 1e17; this
254 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000255
256 There's a new sys attribute sys.float_repr_style, which takes
257 the value 'short' to indicate that we're using short float repr,
258 and 'legacy' if the short float repr isn't available for one
259 reason or another.
260
261 The float repr change involves incorporating David Gay's 'perfect
262 rounding' code into the Python core (it's in Python/dtoa.c). As a
263 secondary consequence, all string-to-float and float-to-string
264 conversions (including all float formatting operations) will be
265 correctly rounded on these platforms.
266
267 See issue 1580 discussions for details of platforms for which
268 this change does not apply.
269
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000270- Issue #5759: float() didn't call __float__ on str subclasses.
271
Georg Brandlabc38772009-04-12 15:51:51 +0000272- The string.maketrans() function is deprecated; there is a new static method
273 maketrans() on the bytes and bytearray classes. This removes confusion about
274 the types string.maketrans() is supposed to work with, and mirrors the
275 methods available on the str class.
276
R. David Murraydc6da8a2009-04-09 22:16:43 +0000277- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
278 its clarity and its speed.
279
Matthias Klose091c7b12009-04-07 13:24:27 +0000280- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
281 to avoid compiler warnings.
282
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000283- Issue #3739: The unicode-internal encoder now reports the number of characters
284 consumed like any other encoder (instead of the number of bytes).

621 amount of loop unrolling.
622
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000623- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
624 collecting the oldest generation) so that allocating lots of objects without
625 destroying them does not show quadratic performance. Based on a proposal by
626 Martin von Löwis at
627 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
628
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000629- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000630 having been closed (for instance, a read() call could return some
631 previously buffered data). Patch by Dmitry Vasiliev.
632
Antoine Pitrou05608432009-01-09 18:53:14 +0000633- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
634 flag to work properly. Furthermore, when specifying -u, the text stdout
635 and stderr streams have line-by-line buffering enabled (the default being
636 to buffer arbitrary chunks of data).
637
Raymond Hettinger35631532009-01-09 03:58:09 +0000638- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
639 instead of ints (reducing its size from 4 to 8 times thereby reducing
640 Python's overall memory).
641
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000642- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
643 an existing .py counterpart, override the co_filename attributes of all
644 code objects if the original filename is obsolete (which can happen if the
645 file has been renamed, moved, or if it is accessed through different paths).
646 Patch by Ziga Seilnacht and Jean-Paul Calderone.
647
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000648- Issue #4580: Fix slicing of memoryviews when the item size is greater than
649 one byte. Also fixes the meaning of len() so that it returns the number of
650 items, rather than the size in bytes.
651
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000652- Issue #4075: Use OutputDebugStringW in Py_FatalError.
653
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000654- Issue #4747: When the terminal does not use utf-8, executing a script with
655 non-ascii characters in its name could fail with a "SyntaxError: None" error.
656
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000657- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

662
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000663- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
664 where the tp_hash and tp_dict slots are both NULL.
665
Georg Brandlccc47b62008-12-28 11:44:14 +0000666- Issue #4759: None is now allowed as the first argument of
667 bytearray.translate(). It was always allowed for bytes.translate().
668
Skip Montanaro80072cb2008-12-23 03:51:14 +0000669- Added test case to ensure attempts to read from a file opened for writing
670 fail.

Antoine Pitrouf289ae62008-12-18 11:06:25 +0000674- Issue #2183: Simplify and optimize bytecode for list, dict and set

676
Antoine Pitrou621601a2008-12-17 23:18:19 +0000677- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
678 print elapsed times, not only when some objects are uncollectable /
679 unreachable. Original patch by Neil Schemenauer.
680
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000681- Issue #3439: Add a bit_length method to int.
682

685 failures on OS X.
686
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000687- Issue #4597: Fixed several opcodes that weren't always propagating
688 exceptions.
689
690- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000691 context manager returns a value that cannot be converted to a bool.
692
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000693- Issue #4445: Replace "sizeof(PyBytesObject)" with
694 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
695 bytes instances. On a typical machine this saves 3 bytes of memory
696 (on average) per allocation of a bytes instance.
697
Christian Heimesa872de52008-12-05 08:26:55 +0000698- Issue #4533: File read operation was dreadfully slow due to a slowly
699 growing read buffer. Fixed by using the same growth rate algorithm as
700 Python 2.x.
701
Antoine Pitrou5504e892008-12-06 21:27:53 +0000702- Issue #4509: Various issues surrounding resize of bytearray objects to
703 which there are buffer exports (e.g. memoryview instances).
704
Georg Brandlf9734072008-12-07 15:30:06 +0000705- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
706 method on file objects with closefd=False. The file descriptor is still
707 kept open but the file object behaves like a closed file. The ``FileIO``
708 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000709
Antoine Pitroubc420402008-12-07 20:14:49 +0000710- Issue #4569: Interpreter crash when mutating a memoryview with an item size
711 larger than 1.
712

716
Walter Dörwaldc1651a02009-05-03 22:55:55 +0000717- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
718 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
719 step. This avoids problems with counting UTF-8 bytes that ignores the effect
720 of using the replace error handler in PyUnicode_DecodeUTF8().
