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

81
Benjamin Peterson14a3dd72009-05-25 00:51:58 +000082- In unittest, using a skipping decorator on a class is now equivalent to
83 skipping every test on the class. The ClassTestSuite class has been removed.
84
Martin v. Löwis70ccd162009-05-24 19:47:22 +000085- Issue #6050: Don't fail extracting a directory from a zipfile if
86 the directory already exists.
87
Antoine Pitrou61f77b52009-05-24 15:46:13 +000088- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
89 than an int, which makes some operations possible under 64-bit Linux (e.g.
90 DN_MULTISHOT with F_NOTIFY).
91
Antoine Pitrou716c4442009-05-23 19:04:03 +000092- Issue #5761: Add the name of the underlying file to the repr() of various

100 a process identifier type wider than the standard C integer type.
101

113
Antoine Pitroue4501852009-05-14 18:55:55 +0000114- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
115 library. This means, for example, that opening an UTF-16 text file in
116 append mode doesn't add a BOM at the end of the file if the file isn't
117 empty.
118
R. David Murray74b89242009-05-13 17:33:03 +0000119- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
120 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
121 corrects a pydoc regression.
122
R. David Murray99352742009-05-07 18:24:38 +0000123- Issue 5955: aifc's close method did not close the file it wrapped,
124 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000162What's New in Python 3.1 beta 1?
163================================
164
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000165*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000166
167Core and Builtins
168-----------------
169
Mark Dickinson865e01a2009-05-07 16:37:01 +0000170- Issue #5914: Add new C API function PyOS_string_to_double, and
171 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
172
Eric Smith741191f2009-05-06 13:08:15 +0000173- Issue #3382: float.__format__, complex.__format__, and %-formatting
174 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
175 affects nan -> NAN and inf -> INF.
176
Mark Hammond5a607a32009-05-06 08:04:54 +0000177- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
178 in all operations, including splitdrive, split, etc. splitunc() now issues
179 a PendingDeprecation warning.
180
Eric Smith63376222009-05-05 14:04:18 +0000181- Issue #5920: For float.__format__, change the behavior with the
182 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
183 to be like 'g' but with at least one decimal point and with a
184 default precision of 12. Previously, the behavior the same but with
185 a default precision of 6. This more closely matches str(), and
186 reduces surprises when adding alignment flags to the empty
187 presentation type. This also affects the new complex.__format__ in
188 the same way.
189
Martin v. Löwis011e8422009-05-05 04:43:17 +0000190- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
191
R. David Murrayb18500d2009-05-04 22:59:07 +0000192- Issue #5890: in subclasses of 'property' the __doc__ attribute was
193 shadowed by classtype's, even if it was None. property now
194 inserts the __doc__ into the subclass instance __dict__.
195
Antoine Pitrou244651a2009-05-04 18:56:13 +0000196- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
197 sequences. Patch by Nick Barnes and Victor Stinner.
198
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000199- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000200
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000201- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
202 received a new method, detach(). detach() disconnects the underlying stream
203 from the buffer or text IO and returns it.
204
Mark Dickinson33841c32009-05-01 15:37:04 +0000205- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
206 floats with absolute value over 1e50. Also remove length
207 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
208 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000209
Eric Smith741191f2009-05-06 13:08:15 +0000210- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000211 format(complex(1, 2./3), '.5') now produces a sensible result.
212
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000213- Issue #5864: Fix empty format code formatting for floats so that it
214 never gives more than the requested number of significant digits.
215
Eric Smith6dc46f52009-04-27 20:39:49 +0000216- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
217 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
218
Eric Smithcc32a112009-04-26 21:35:14 +0000219- Issue #5835: Deprecate PyOS_ascii_formatd.
220
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000221- Issue #4971: Fix titlecase for characters that are their own
222 titlecase, but not their own uppercase.
223
Benjamin Peterson193152c2009-04-25 01:08:45 +0000224- Issue #5283: Setting __class__ in __del__ caused a segfault.
225
Mark Dickinsonad476da2009-04-23 19:14:16 +0000226- Issue #5816: complex(repr(z)) now recovers z exactly, even when
227 z involves nans, infs or negative zeros.
228
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000229- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000230
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000231- Issue #1869 (and many duplicates): make round(x, n) correctly
232 rounded for a float x, by using the decimal <-> binary conversions
233 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
234 consistently agrees with format(x, '.2f').
235
Benjamin Petersonae937c02009-04-18 20:54:08 +0000236- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
237 some builtin types.
238
Eric Smith0923d1d2009-04-16 20:16:10 +0000239- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
240
Eric Smith35e84722009-04-16 20:21:28 +0000241- Issue #5515: str.format() type 'n' combined with commas and leading
242 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000243
244- Implement PEP 378, Format Specifier for Thousands Separator, for
245 floats.
246
Mark Dickinson3370cce2009-04-17 22:40:53 +0000247- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000248 1e11, not 1e12. This avoids printing 13 significant digits in
249 situations where only 12 of them are correct. Example problem
250 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
251 long time.)
252
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000253- Issue #1580: On most platforms, use a 'short' float repr: for a
254 finite float x, repr(x) now outputs a string based on the shortest
255 sequence of decimal digits that rounds to x. Previous behaviour was
256 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000257 Another minor difference is that the new repr switches to
258 exponential notation at 1e16 instead of the previous 1e17; this
259 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000260
261 There's a new sys attribute sys.float_repr_style, which takes
262 the value 'short' to indicate that we're using short float repr,
263 and 'legacy' if the short float repr isn't available for one
264 reason or another.
265
266 The float repr change involves incorporating David Gay's 'perfect
267 rounding' code into the Python core (it's in Python/dtoa.c). As a
268 secondary consequence, all string-to-float and float-to-string
269 conversions (including all float formatting operations) will be
270 correctly rounded on these platforms.
271
272 See issue 1580 discussions for details of platforms for which
273 this change does not apply.
274
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000275- Issue #5759: float() didn't call __float__ on str subclasses.
276
Georg Brandlabc38772009-04-12 15:51:51 +0000277- The string.maketrans() function is deprecated; there is a new static method
278 maketrans() on the bytes and bytearray classes. This removes confusion about
279 the types string.maketrans() is supposed to work with, and mirrors the
280 methods available on the str class.
281
R. David Murraydc6da8a2009-04-09 22:16:43 +0000282- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
283 its clarity and its speed.
284
Matthias Klose091c7b12009-04-07 13:24:27 +0000285- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
286 to avoid compiler warnings.
287
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000288- Issue #3739: The unicode-internal encoder now reports the number of characters
289 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrouab868312009-01-10 15:40:25 +0000624- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
625 common cases are optimized thanks to a dedicated fast path and a moderate
626 amount of loop unrolling.
627
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000628- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
629 collecting the oldest generation) so that allocating lots of objects without
630 destroying them does not show quadratic performance. Based on a proposal by
631 Martin von Löwis at
632 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
633
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000634- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000635 having been closed (for instance, a read() call could return some
636 previously buffered data). Patch by Dmitry Vasiliev.
637
Antoine Pitrou05608432009-01-09 18:53:14 +0000638- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
639 flag to work properly. Furthermore, when specifying -u, the text stdout
640 and stderr streams have line-by-line buffering enabled (the default being
641 to buffer arbitrary chunks of data).
642
Raymond Hettinger35631532009-01-09 03:58:09 +0000643- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
644 instead of ints (reducing its size from 4 to 8 times thereby reducing
645 Python's overall memory).
646
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000647- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
648 an existing .py counterpart, override the co_filename attributes of all
649 code objects if the original filename is obsolete (which can happen if the
650 file has been renamed, moved, or if it is accessed through different paths).
651 Patch by Ziga Seilnacht and Jean-Paul Calderone.
652
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000653- Issue #4580: Fix slicing of memoryviews when the item size is greater than
654 one byte. Also fixes the meaning of len() so that it returns the number of
655 items, rather than the size in bytes.
656
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000657- Issue #4075: Use OutputDebugStringW in Py_FatalError.
658
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000659- Issue #4747: When the terminal does not use utf-8, executing a script with
660 non-ascii characters in its name could fail with a "SyntaxError: None" error.
661
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000662- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

Antoine Pitrou7ddda782009-01-01 15:35:33 +0000665- Issue #3680: Reference cycles created through a dict, set or deque iterator
666 did not get collected.
667
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000668- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
669 where the tp_hash and tp_dict slots are both NULL.
670
Georg Brandlccc47b62008-12-28 11:44:14 +0000671- Issue #4759: None is now allowed as the first argument of
672 bytearray.translate(). It was always allowed for bytes.translate().
673
Skip Montanaro80072cb2008-12-23 03:51:14 +0000674- Added test case to ensure attempts to read from a file opened for writing
675 fail.
676

Antoine Pitrouf289ae62008-12-18 11:06:25 +0000679- Issue #2183: Simplify and optimize bytecode for list, dict and set
680 comprehensions. Original patch for list comprehensions by Neal Norwitz.
681
Antoine Pitrou621601a2008-12-17 23:18:19 +0000682- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
683 print elapsed times, not only when some objects are uncollectable /
684 unreachable. Original patch by Neil Schemenauer.
685
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000686- Issue #3439: Add a bit_length method to int.
687
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000688- Issue #2173: When getting device encoding, check that return value of
689 nl_langinfo is not the empty string. This was causing silent build
690 failures on OS X.
691
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000692- Issue #4597: Fixed several opcodes that weren't always propagating
693 exceptions.
694
695- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000696 context manager returns a value that cannot be converted to a bool.
697
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000698- Issue #4445: Replace "sizeof(PyBytesObject)" with
699 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
700 bytes instances. On a typical machine this saves 3 bytes of memory
701 (on average) per allocation of a bytes instance.
702
Christian Heimesa872de52008-12-05 08:26:55 +0000703- Issue #4533: File read operation was dreadfully slow due to a slowly
704 growing read buffer. Fixed by using the same growth rate algorithm as
705 Python 2.x.
706
Antoine Pitrou5504e892008-12-06 21:27:53 +0000707- Issue #4509: Various issues surrounding resize of bytearray objects to
708 which there are buffer exports (e.g. memoryview instances).
709
Georg Brandlf9734072008-12-07 15:30:06 +0000710- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
711 method on file objects with closefd=False. The file descriptor is still
712 kept open but the file object behaves like a closed file. The ``FileIO``
713 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000714
Antoine Pitroubc420402008-12-07 20:14:49 +0000715- Issue #4569: Interpreter crash when mutating a memoryview with an item size
716 larger than 1.
717

721
Walter Dörwaldc1651a02009-05-03 22:55:55 +0000722- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
723 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
724 step. This avoids problems with counting UTF-8 bytes that ignores the effect
725 of using the replace error handler in PyUnicode_DecodeUTF8().
