595Core and Builtins
596-----------------
597
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000598- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
599 of the command line.
600
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000601- Issue #6012: Add cleanup support to O& argument parsing.
602
Eric Smith41669ca2009-05-23 14:23:22 +0000603- Issue #6089: Fixed str.format with certain invalid field specifiers
604 that would raise SystemError.
605
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000606- Issue #5982: staticmethod and classmethod now expose the wrapped
607 function with __func__.
608
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000609- Added support for multiple context managers in the same with-statement.
610 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000611
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000612- Issue #5829: complex("1e500") no longer raises OverflowError. This
613 makes it consistent with float("1e500") and interpretation of real
614 and imaginary literals.
615
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000616- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

619
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000620- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
621 (1) inf and nan strings with trailing whitespace were incorrectly
622 rejected; (2) parsing of strings representing infinities and nans
623 was locale aware; and (3) the interpretation of fromhex('-nan')
624 didn't match that of float('-nan').

627-------
628
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000629- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
630

632
R. David Murray1f1b9d32009-05-27 20:56:59 +0000633- Issue #6121: pydoc now ignores leading and trailing spaces in the
634 argument to the 'help' function.
635
Georg Brandlfaf41492009-05-26 18:31:11 +0000636- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
637 arguments for strings with a space in them.
638
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000639- collections.namedtuple() was not working with the following field
640 names: cls, self, tuple, itemgetter, and property.
641
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000642- In unittest, using a skipping decorator on a class is now equivalent to
643 skipping every test on the class. The ClassTestSuite class has been removed.
644
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000645- Issue #6050: Don't fail extracting a directory from a zipfile if
646 the directory already exists.
647
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000648- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
649 than an int, which makes some operations possible under 64-bit Linux (e.g.
650 DN_MULTISHOT with F_NOTIFY).
651
Antoine Pitrou716c4442009-05-23 19:04:03 +0000652- Issue #5761: Add the name of the underlying file to the repr() of various

654
R. David Murraycaa27b72009-05-23 18:49:56 +0000655- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
656 by Musashi Tamura, tests by Marcin Bachry.
657
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000658- Issue #1983: Fix functions taking or returning a process identifier to use
659 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
660 a process identifier type wider than the standard C integer type.
661
R. David Murray87e20742009-05-23 01:30:26 +0000662- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
663 Patch by Farhan Ahmad, test by Marcin Bachry.
664

673
Antoine Pitroue4501852009-05-14 18:55:55 +0000674- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
675 library. This means, for example, that opening an UTF-16 text file in
676 append mode doesn't add a BOM at the end of the file if the file isn't
677 empty.
678
R. David Murray74b89242009-05-13 17:33:03 +0000679- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
680 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
681 corrects a pydoc regression.
682
R. David Murray99352742009-05-07 18:24:38 +0000683- Issue 5955: aifc's close method did not close the file it wrapped,
684 now it does. This also means getfp method now returns the real fp.
685
Benjamin Peterson932073a2009-05-23 16:14:33 +0000686Installation
687------------

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000722What's New in Python 3.1 beta 1?
723================================
724
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000725*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000726
727Core and Builtins
728-----------------
729
Mark Dickinson865e01a2009-05-07 16:37:01 +0000730- Issue #5914: Add new C API function PyOS_string_to_double, and
731 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
732
Eric Smith741191f2009-05-06 13:08:15 +0000733- Issue #3382: float.__format__, complex.__format__, and %-formatting
734 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
735 affects nan -> NAN and inf -> INF.
736
Mark Hammond5a607a32009-05-06 08:04:54 +0000737- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
738 in all operations, including splitdrive, split, etc. splitunc() now issues
739 a PendingDeprecation warning.
740
Eric Smith63376222009-05-05 14:04:18 +0000741- Issue #5920: For float.__format__, change the behavior with the
742 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
743 to be like 'g' but with at least one decimal point and with a
744 default precision of 12. Previously, the behavior the same but with
745 a default precision of 6. This more closely matches str(), and
746 reduces surprises when adding alignment flags to the empty
747 presentation type. This also affects the new complex.__format__ in
748 the same way.
749
Martin v. Löwis011e8422009-05-05 04:43:17 +0000750- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
751
R. David Murrayb18500d2009-05-04 22:59:07 +0000752- Issue #5890: in subclasses of 'property' the __doc__ attribute was
753 shadowed by classtype's, even if it was None. property now
754 inserts the __doc__ into the subclass instance __dict__.
755
Antoine Pitrou244651a2009-05-04 18:56:13 +0000756- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
757 sequences. Patch by Nick Barnes and Victor Stinner.
758
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000759- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000760
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000761- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
762 received a new method, detach(). detach() disconnects the underlying stream
763 from the buffer or text IO and returns it.
764
Mark Dickinson33841c32009-05-01 15:37:04 +0000765- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
766 floats with absolute value over 1e50. Also remove length
767 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
768 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000769
Eric Smith741191f2009-05-06 13:08:15 +0000770- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000771 format(complex(1, 2./3), '.5') now produces a sensible result.
772
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000773- Issue #5864: Fix empty format code formatting for floats so that it
774 never gives more than the requested number of significant digits.
775
Eric Smith6dc46f52009-04-27 20:39:49 +0000776- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
777 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
778
Eric Smithcc32a112009-04-26 21:35:14 +0000779- Issue #5835: Deprecate PyOS_ascii_formatd.
780
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000781- Issue #4971: Fix titlecase for characters that are their own
782 titlecase, but not their own uppercase.
783
Benjamin Peterson193152c2009-04-25 01:08:45 +0000784- Issue #5283: Setting __class__ in __del__ caused a segfault.
785
Mark Dickinsonad476da2009-04-23 19:14:16 +0000786- Issue #5816: complex(repr(z)) now recovers z exactly, even when
787 z involves nans, infs or negative zeros.
788
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000789- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000790
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000791- Issue #1869 (and many duplicates): make round(x, n) correctly
792 rounded for a float x, by using the decimal <-> binary conversions
793 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
794 consistently agrees with format(x, '.2f').
795
Benjamin Petersonae937c02009-04-18 20:54:08 +0000796- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
797 some builtin types.
798
Eric Smith0923d1d2009-04-16 20:16:10 +0000799- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
800
Eric Smith35e84722009-04-16 20:21:28 +0000801- Issue #5515: str.format() type 'n' combined with commas and leading
802 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000803
804- Implement PEP 378, Format Specifier for Thousands Separator, for
805 floats.
806
Mark Dickinson3370cce2009-04-17 22:40:53 +0000807- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000808 1e11, not 1e12. This avoids printing 13 significant digits in
809 situations where only 12 of them are correct. Example problem
810 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
811 long time.)
812
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000813- Issue #1580: On most platforms, use a 'short' float repr: for a
814 finite float x, repr(x) now outputs a string based on the shortest
815 sequence of decimal digits that rounds to x. Previous behaviour was
816 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000817 Another minor difference is that the new repr switches to
818 exponential notation at 1e16 instead of the previous 1e17; this
819 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000820
821 There's a new sys attribute sys.float_repr_style, which takes
822 the value 'short' to indicate that we're using short float repr,
823 and 'legacy' if the short float repr isn't available for one
824 reason or another.
825
826 The float repr change involves incorporating David Gay's 'perfect
827 rounding' code into the Python core (it's in Python/dtoa.c). As a
828 secondary consequence, all string-to-float and float-to-string
829 conversions (including all float formatting operations) will be
830 correctly rounded on these platforms.
831
832 See issue 1580 discussions for details of platforms for which
833 this change does not apply.
834
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000835- Issue #5759: float() didn't call __float__ on str subclasses.
836
Georg Brandlabc38772009-04-12 15:51:51 +0000837- The string.maketrans() function is deprecated; there is a new static method
838 maketrans() on the bytes and bytearray classes. This removes confusion about
839 the types string.maketrans() is supposed to work with, and mirrors the
840 methods available on the str class.
841
R. David Murraydc6da8a2009-04-09 22:16:43 +0000842- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
843 its clarity and its speed.
844
Matthias Klose091c7b12009-04-07 13:24:27 +0000845- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
846 to avoid compiler warnings.
847
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000848- Issue #3739: The unicode-internal encoder now reports the number of characters
849 consumed like any other encoder (instead of the number of bytes).

864
Vinay Sajipaffbd872009-06-11 10:11:47 +0000865- Issue #5940: distutils.command.build_clib.check_library_list was not doing

1007 untrackable objects are not tracked by the garbage collector. This can
1008 reduce the size of collections and therefore the garbage collection overhead
1009 on long-running programs, depending on their particular use of datatypes.

1190 destroying them does not show quadratic performance. Based on a proposal by
1191 Martin von Löwis at
1192 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1193
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001194- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001195 having been closed (for instance, a read() call could return some
1196 previously buffered data). Patch by Dmitry Vasiliev.
1197
Antoine Pitrou05608432009-01-09 18:53:14 +00001198- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1199 flag to work properly. Furthermore, when specifying -u, the text stdout
1200 and stderr streams have line-by-line buffering enabled (the default being
1201 to buffer arbitrary chunks of data).
1202
Raymond Hettinger35631532009-01-09 03:58:09 +00001203- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1204 instead of ints (reducing its size from 4 to 8 times thereby reducing
1205 Python's overall memory).
1206
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001207- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1208 an existing .py counterpart, override the co_filename attributes of all
1209 code objects if the original filename is obsolete (which can happen if the
1210 file has been renamed, moved, or if it is accessed through different paths).
1211 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1212
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001213- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1214 one byte. Also fixes the meaning of len() so that it returns the number of
1215 items, rather than the size in bytes.
1216
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001217- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1218
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001219- Issue #4747: When the terminal does not use utf-8, executing a script with
1220 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1221
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001222- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001223 file with `bytes' filename on Windows.

1226 did not get collected.
1227
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001228- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1229 where the tp_hash and tp_dict slots are both NULL.
1230
Georg Brandlccc47b62008-12-28 11:44:14 +00001231- Issue #4759: None is now allowed as the first argument of
1232 bytearray.translate(). It was always allowed for bytes.translate().
1233
Skip Montanaro80072cb2008-12-23 03:51:14 +00001234- Added test case to ensure attempts to read from a file opened for writing
1235 fail.
1236
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001237- Issue #3106: Speedup some comparisons (str/str and int/int).

1241
Antoine Pitrou621601a2008-12-17 23:18:19 +00001242- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1244 unreachable. Original patch by Neil Schemenauer.
1245

1249 nl_langinfo is not the empty string. This was causing silent build
1250 failures on OS X.
1251
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001252- Issue #4597: Fixed several opcodes that weren't always propagating
1253 exceptions.
1254
1255- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001256 context manager returns a value that cannot be converted to a bool.
1257
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001258- Issue #4445: Replace "sizeof(PyBytesObject)" with
1259 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1260 bytes instances. On a typical machine this saves 3 bytes of memory
1261 (on average) per allocation of a bytes instance.
1262
Christian Heimesa872de52008-12-05 08:26:55 +00001263- Issue #4533: File read operation was dreadfully slow due to a slowly
1264 growing read buffer. Fixed by using the same growth rate algorithm as
1265 Python 2.x.
1266
Antoine Pitrou5504e892008-12-06 21:27:53 +00001267- Issue #4509: Various issues surrounding resize of bytearray objects to
1268 which there are buffer exports (e.g. memoryview instances).
1269
Georg Brandlf9734072008-12-07 15:30:06 +00001270- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1271 method on file objects with closefd=False. The file descriptor is still
1272 kept open but the file object behaves like a closed file. The ``FileIO``
1273 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00001275- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1281
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001282- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1283 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1284 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1285 of using the replace error handler in PyUnicode_DecodeUTF8().

1562
Antoine Pitrou08838b62009-01-21 00:55:13 +00001563- Issue #5008: When a file is opened in append mode with the new IO library,
1564 do an explicit seek to the end of file (so that e.g. tell() returns the
1565 file size rather than 0). This is consistent with the behaviour of the

1596 appropriately when it is being used via socket.makefile() objects
1597 rather than delaying the close by waiting for garbage collection to do it.
