14
Amaury Forgeot d'Arc66f8c432009-06-09 21:30:01 +000015- Issue #5924: On Windows, a large PYTHONPATH environment variable
16 (more than 255 characters) would be completely ignored.
17
Amaury Forgeot d'Arc24e581f2009-06-01 21:28:37 +000018- Issue #4547: When debugging a very large function, it was not always

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

113
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000114- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.

125 names: cls, self, tuple, itemgetter, and property.
126
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000127- In unittest, using a skipping decorator on a class is now equivalent to
128 skipping every test on the class. The ClassTestSuite class has been removed.
129
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000130- Issue #6050: Don't fail extracting a directory from a zipfile if
131 the directory already exists.
132
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000133- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
134 than an int, which makes some operations possible under 64-bit Linux (e.g.
135 DN_MULTISHOT with F_NOTIFY).
136
Antoine Pitrou716c4442009-05-23 19:04:03 +0000137- Issue #5761: Add the name of the underlying file to the repr() of various

142
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000143- Issue #1983: Fix functions taking or returning a process identifier to use
144 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
145 a process identifier type wider than the standard C integer type.
146
R. David Murray87e20742009-05-23 01:30:26 +0000147- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
148 Patch by Farhan Ahmad, test by Marcin Bachry.
149
Antoine Pitrou6e610062009-05-15 17:04:50 +0000150- Issue #2116: Weak references and weak dictionaries now support copy()ing and

158
Antoine Pitroue4501852009-05-14 18:55:55 +0000159- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
160 library. This means, for example, that opening an UTF-16 text file in
161 append mode doesn't add a BOM at the end of the file if the file isn't
162 empty.
163
R. David Murray74b89242009-05-13 17:33:03 +0000164- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
165 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
166 corrects a pydoc regression.
167
R. David Murray99352742009-05-07 18:24:38 +0000168- Issue 5955: aifc's close method did not close the file it wrapped,
169 now it does. This also means getfp method now returns the real fp.
170
Benjamin Peterson932073a2009-05-23 16:14:33 +0000171Installation
172------------
173

Brett Cannon1262e7c2009-05-11 01:47:11 +0000198Tests
199-----
200
201- Issue 5442: Tests for importlib were not properly skipping case-sensitivity

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000207What's New in Python 3.1 beta 1?
208================================
209
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000210*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000211
212Core and Builtins
213-----------------
214
Mark Dickinson865e01a2009-05-07 16:37:01 +0000215- Issue #5914: Add new C API function PyOS_string_to_double, and
216 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
217
Eric Smith741191f2009-05-06 13:08:15 +0000218- Issue #3382: float.__format__, complex.__format__, and %-formatting
219 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
220 affects nan -> NAN and inf -> INF.
221
Mark Hammond5a607a32009-05-06 08:04:54 +0000222- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
223 in all operations, including splitdrive, split, etc. splitunc() now issues
224 a PendingDeprecation warning.
225
Eric Smith63376222009-05-05 14:04:18 +0000226- Issue #5920: For float.__format__, change the behavior with the
227 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
228 to be like 'g' but with at least one decimal point and with a
229 default precision of 12. Previously, the behavior the same but with
230 a default precision of 6. This more closely matches str(), and
231 reduces surprises when adding alignment flags to the empty
232 presentation type. This also affects the new complex.__format__ in
233 the same way.
234
Martin v. Löwis011e8422009-05-05 04:43:17 +0000235- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
236
R. David Murrayb18500d2009-05-04 22:59:07 +0000237- Issue #5890: in subclasses of 'property' the __doc__ attribute was
238 shadowed by classtype's, even if it was None. property now
239 inserts the __doc__ into the subclass instance __dict__.
240
Antoine Pitrou244651a2009-05-04 18:56:13 +0000241- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
242 sequences. Patch by Nick Barnes and Victor Stinner.
243
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000244- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000245
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000246- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
247 received a new method, detach(). detach() disconnects the underlying stream
248 from the buffer or text IO and returns it.
249
Mark Dickinson33841c32009-05-01 15:37:04 +0000250- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
251 floats with absolute value over 1e50. Also remove length
252 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
253 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000254
Eric Smith741191f2009-05-06 13:08:15 +0000255- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000256 format(complex(1, 2./3), '.5') now produces a sensible result.
257
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000258- Issue #5864: Fix empty format code formatting for floats so that it
259 never gives more than the requested number of significant digits.
260
Eric Smith6dc46f52009-04-27 20:39:49 +0000261- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
262 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
263
Eric Smithcc32a112009-04-26 21:35:14 +0000264- Issue #5835: Deprecate PyOS_ascii_formatd.
265
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000266- Issue #4971: Fix titlecase for characters that are their own
267 titlecase, but not their own uppercase.
268
Benjamin Peterson193152c2009-04-25 01:08:45 +0000269- Issue #5283: Setting __class__ in __del__ caused a segfault.
270
Mark Dickinsonad476da2009-04-23 19:14:16 +0000271- Issue #5816: complex(repr(z)) now recovers z exactly, even when
272 z involves nans, infs or negative zeros.
273
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000274- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000275
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000276- Issue #1869 (and many duplicates): make round(x, n) correctly
277 rounded for a float x, by using the decimal <-> binary conversions
278 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
279 consistently agrees with format(x, '.2f').
280
Benjamin Petersonae937c02009-04-18 20:54:08 +0000281- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
282 some builtin types.
283
Eric Smith0923d1d2009-04-16 20:16:10 +0000284- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
285
Eric Smith35e84722009-04-16 20:21:28 +0000286- Issue #5515: str.format() type 'n' combined with commas and leading
287 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000288
289- Implement PEP 378, Format Specifier for Thousands Separator, for
290 floats.
291
Mark Dickinson3370cce2009-04-17 22:40:53 +0000292- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000293 1e11, not 1e12. This avoids printing 13 significant digits in
294 situations where only 12 of them are correct. Example problem
295 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
296 long time.)
297
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000298- Issue #1580: On most platforms, use a 'short' float repr: for a
299 finite float x, repr(x) now outputs a string based on the shortest
300 sequence of decimal digits that rounds to x. Previous behaviour was
301 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000302 Another minor difference is that the new repr switches to
303 exponential notation at 1e16 instead of the previous 1e17; this
304 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000305
306 There's a new sys attribute sys.float_repr_style, which takes
307 the value 'short' to indicate that we're using short float repr,
308 and 'legacy' if the short float repr isn't available for one
309 reason or another.
310
311 The float repr change involves incorporating David Gay's 'perfect
312 rounding' code into the Python core (it's in Python/dtoa.c). As a
313 secondary consequence, all string-to-float and float-to-string
314 conversions (including all float formatting operations) will be
315 correctly rounded on these platforms.
316

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000630- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000631 were suppressing all exceptions. These include list() and bytearray().
632
Mark Dickinson1124e712009-01-28 21:25:58 +0000633- Issue #4707: round(x, n) now returns an integer if x is an integer.
634 Previously it returned a float.
635
Antoine Pitroub52ec782009-01-25 16:34:23 +0000636- Issue #4753: By enabling a configure option named '--with-computed-gotos'
637 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
638 evaluation loop is compiled with a new dispatch mechanism which gives
639 speedups of up to 20%, depending on the system, on various benchmarks.

650
Mark Dickinson8055afd2009-01-17 10:04:45 +0000651- Issue #4910: Rename nb_long slot to nb_reserved, and change its
652 type to (void *).
653
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000654- Issue #4935: The overflow checking code in the expandtabs() method common
655 to str, bytes and bytearray could be optimized away by the compiler, letting
656 the interpreter segfault instead of raising an error.
657
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000658- Issue #3720: Fix a crash when an iterator modifies its class and removes its
659 __next__ method.
660
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000661- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
662 function no longer attempt to call the __long__ slot to convert an object
663 to an integer. Only the __int__ and __trunc__ slots are examined.

668
Antoine Pitrouab868312009-01-10 15:40:25 +0000669- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
670 common cases are optimized thanks to a dedicated fast path and a moderate
671 amount of loop unrolling.
672
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000673- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
674 collecting the oldest generation) so that allocating lots of objects without
675 destroying them does not show quadratic performance. Based on a proposal by
676 Martin von Löwis at
677 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
678
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000679- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000680 having been closed (for instance, a read() call could return some
681 previously buffered data). Patch by Dmitry Vasiliev.
682
Antoine Pitrou05608432009-01-09 18:53:14 +0000683- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
684 flag to work properly. Furthermore, when specifying -u, the text stdout
685 and stderr streams have line-by-line buffering enabled (the default being
686 to buffer arbitrary chunks of data).
687
Raymond Hettinger35631532009-01-09 03:58:09 +0000688- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
689 instead of ints (reducing its size from 4 to 8 times thereby reducing
690 Python's overall memory).
691
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000692- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
693 an existing .py counterpart, override the co_filename attributes of all
694 code objects if the original filename is obsolete (which can happen if the
695 file has been renamed, moved, or if it is accessed through different paths).
696 Patch by Ziga Seilnacht and Jean-Paul Calderone.
697
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000698- Issue #4580: Fix slicing of memoryviews when the item size is greater than
699 one byte. Also fixes the meaning of len() so that it returns the number of
700 items, rather than the size in bytes.
701
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000702- Issue #4075: Use OutputDebugStringW in Py_FatalError.
703
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000704- Issue #4747: When the terminal does not use utf-8, executing a script with
705 non-ascii characters in its name could fail with a "SyntaxError: None" error.
706
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000707- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

711 did not get collected.
712
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000713- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
714 where the tp_hash and tp_dict slots are both NULL.
715
Georg Brandlccc47b62008-12-28 11:44:14 +0000716- Issue #4759: None is now allowed as the first argument of
717 bytearray.translate(). It was always allowed for bytes.translate().
718
Skip Montanaro80072cb2008-12-23 03:51:14 +0000719- Added test case to ensure attempts to read from a file opened for writing
720 fail.

726
Antoine Pitrou621601a2008-12-17 23:18:19 +0000727- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

729 unreachable. Original patch by Neil Schemenauer.
730
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000731- Issue #3439: Add a bit_length method to int.
732
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000733- Issue #2173: When getting device encoding, check that return value of
734 nl_langinfo is not the empty string. This was causing silent build
735 failures on OS X.
736
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000737- Issue #4597: Fixed several opcodes that weren't always propagating
738 exceptions.
739
740- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000741 context manager returns a value that cannot be converted to a bool.
742
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000743- Issue #4445: Replace "sizeof(PyBytesObject)" with
744 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
745 bytes instances. On a typical machine this saves 3 bytes of memory
746 (on average) per allocation of a bytes instance.
747
Christian Heimesa872de52008-12-05 08:26:55 +0000748- Issue #4533: File read operation was dreadfully slow due to a slowly
749 growing read buffer. Fixed by using the same growth rate algorithm as
750 Python 2.x.
751
Antoine Pitrou5504e892008-12-06 21:27:53 +0000752- Issue #4509: Various issues surrounding resize of bytearray objects to
753 which there are buffer exports (e.g. memoryview instances).
754
Georg Brandlf9734072008-12-07 15:30:06 +0000755- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
756 method on file objects with closefd=False. The file descriptor is still
757 kept open but the file object behaves like a closed file. The ``FileIO``
758 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000759
Antoine Pitroubc420402008-12-07 20:14:49 +0000760- Issue #4569: Interpreter crash when mutating a memoryview with an item size

766
Walter Dörwaldc1651a02009-05-03 22:55:55 +0000767- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
768 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
769 step. This avoids problems with counting UTF-8 bytes that ignores the effect
770 of using the replace error handler in PyUnicode_DecodeUTF8().
