181 to execute file paths that refer to source or compiled Python files as well
182 as zipfiles, directories and other valid sys.path entries that contain a
183 __main__.py file. This allows applications that run other Python scripts to
184 support the same flexibility as the CPython command line itself.

216
Gregory P. Smith50467882009-11-01 18:42:17 +0000217- Issue #7246 & Issue #7208: getpass now properly flushes input before
218 reading from stdin so that existing input does not confuse it and
219 lead to incorrect entry or an IOError. It also properly flushes it
220 afterwards to avoid the terminal echoing the input afterwards on
221 OSes such as Solaris.
222
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000223- Issue #7233: Fix a number of two-argument Decimal methods to make

453 the encodings package, which would make other tests fail further down
454 the road because the internally cached encoders and decoders would point
455 to empty global variables.
456

471 leak-chasing test runs give sensible results. The previous method of

621Core and Builtins
622-----------------
623
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000624- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
625 of the command line.
626
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000627- Issue #6012: Add cleanup support to O& argument parsing.
628
Eric Smith41669ca2009-05-23 14:23:22 +0000629- Issue #6089: Fixed str.format with certain invalid field specifiers
630 that would raise SystemError.
631
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000632- Issue #5982: staticmethod and classmethod now expose the wrapped
633 function with __func__.
634
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000635- Added support for multiple context managers in the same with-statement.
636 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000637
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000638- Issue #5829: complex("1e500") no longer raises OverflowError. This
639 makes it consistent with float("1e500") and interpretation of real
640 and imaginary literals.
641
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000642- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

645
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000646- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
647 (1) inf and nan strings with trailing whitespace were incorrectly
648 rejected; (2) parsing of strings representing infinities and nans
649 was locale aware; and (3) the interpretation of fromhex('-nan')
650 didn't match that of float('-nan').

653-------
654
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000655- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
656
R. David Murrayfb123912009-05-28 18:19:00 +0000657- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
658
R. David Murray1f1b9d32009-05-27 20:56:59 +0000659- Issue #6121: pydoc now ignores leading and trailing spaces in the
660 argument to the 'help' function.
661
Georg Brandlfaf41492009-05-26 18:31:11 +0000662- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
663 arguments for strings with a space in them.
664
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000665- collections.namedtuple() was not working with the following field
666 names: cls, self, tuple, itemgetter, and property.
667
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000668- In unittest, using a skipping decorator on a class is now equivalent to
669 skipping every test on the class. The ClassTestSuite class has been removed.
670
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000671- Issue #6050: Don't fail extracting a directory from a zipfile if
672 the directory already exists.
673
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000674- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
675 than an int, which makes some operations possible under 64-bit Linux (e.g.
676 DN_MULTISHOT with F_NOTIFY).
677
Antoine Pitrou716c4442009-05-23 19:04:03 +0000678- Issue #5761: Add the name of the underlying file to the repr() of various

680
R. David Murraycaa27b72009-05-23 18:49:56 +0000681- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
682 by Musashi Tamura, tests by Marcin Bachry.
683
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000684- Issue #1983: Fix functions taking or returning a process identifier to use
685 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
686 a process identifier type wider than the standard C integer type.
687
R. David Murray87e20742009-05-23 01:30:26 +0000688- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
689 Patch by Farhan Ahmad, test by Marcin Bachry.
690

699
Antoine Pitroue4501852009-05-14 18:55:55 +0000700- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
701 library. This means, for example, that opening an UTF-16 text file in
702 append mode doesn't add a BOM at the end of the file if the file isn't
703 empty.
704
R. David Murray74b89242009-05-13 17:33:03 +0000705- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
706 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
707 corrects a pydoc regression.
708
R. David Murray99352742009-05-07 18:24:38 +0000709- Issue 5955: aifc's close method did not close the file it wrapped,
710 now it does. This also means getfp method now returns the real fp.
711
Benjamin Peterson932073a2009-05-23 16:14:33 +0000712Installation
713------------

738
Brett Cannon1262e7c2009-05-11 01:47:11 +0000739Tests
740-----
741
742- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
743 tests on darwin even when the OS was installed on a case-sensitive
744 filesystem. Also fixed tests that should not be run when
745 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000748What's New in Python 3.1 beta 1?
749================================
750
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000751*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000752
753Core and Builtins
754-----------------
755
Mark Dickinson865e01a2009-05-07 16:37:01 +0000756- Issue #5914: Add new C API function PyOS_string_to_double, and
757 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
758
Eric Smith741191f2009-05-06 13:08:15 +0000759- Issue #3382: float.__format__, complex.__format__, and %-formatting
760 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
761 affects nan -> NAN and inf -> INF.
762
Mark Hammond5a607a32009-05-06 08:04:54 +0000763- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
764 in all operations, including splitdrive, split, etc. splitunc() now issues
765 a PendingDeprecation warning.
766
Eric Smith63376222009-05-05 14:04:18 +0000767- Issue #5920: For float.__format__, change the behavior with the
768 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
769 to be like 'g' but with at least one decimal point and with a
770 default precision of 12. Previously, the behavior the same but with
771 a default precision of 6. This more closely matches str(), and
772 reduces surprises when adding alignment flags to the empty
773 presentation type. This also affects the new complex.__format__ in
774 the same way.
775
Martin v. Löwis011e8422009-05-05 04:43:17 +0000776- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
777
R. David Murrayb18500d2009-05-04 22:59:07 +0000778- Issue #5890: in subclasses of 'property' the __doc__ attribute was
779 shadowed by classtype's, even if it was None. property now
780 inserts the __doc__ into the subclass instance __dict__.
781
Antoine Pitrou244651a2009-05-04 18:56:13 +0000782- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
783 sequences. Patch by Nick Barnes and Victor Stinner.
784
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000785- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000786
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000787- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
788 received a new method, detach(). detach() disconnects the underlying stream
789 from the buffer or text IO and returns it.
790
Mark Dickinson33841c32009-05-01 15:37:04 +0000791- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
792 floats with absolute value over 1e50. Also remove length
793 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
794 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000795
Eric Smith741191f2009-05-06 13:08:15 +0000796- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000797 format(complex(1, 2./3), '.5') now produces a sensible result.
798
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000799- Issue #5864: Fix empty format code formatting for floats so that it
800 never gives more than the requested number of significant digits.
801
Eric Smith6dc46f52009-04-27 20:39:49 +0000802- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
803 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
804
Eric Smithcc32a112009-04-26 21:35:14 +0000805- Issue #5835: Deprecate PyOS_ascii_formatd.
806
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000807- Issue #4971: Fix titlecase for characters that are their own
808 titlecase, but not their own uppercase.
809
Benjamin Peterson193152c2009-04-25 01:08:45 +0000810- Issue #5283: Setting __class__ in __del__ caused a segfault.
811
Mark Dickinsonad476da2009-04-23 19:14:16 +0000812- Issue #5816: complex(repr(z)) now recovers z exactly, even when
813 z involves nans, infs or negative zeros.
814
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000815- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000816
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000817- Issue #1869 (and many duplicates): make round(x, n) correctly
818 rounded for a float x, by using the decimal <-> binary conversions
819 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
820 consistently agrees with format(x, '.2f').
821
Benjamin Petersonae937c02009-04-18 20:54:08 +0000822- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
823 some builtin types.
824
Eric Smith0923d1d2009-04-16 20:16:10 +0000825- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
826
Eric Smith35e84722009-04-16 20:21:28 +0000827- Issue #5515: str.format() type 'n' combined with commas and leading
828 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000829
830- Implement PEP 378, Format Specifier for Thousands Separator, for
831 floats.
832
Mark Dickinson3370cce2009-04-17 22:40:53 +0000833- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000834 1e11, not 1e12. This avoids printing 13 significant digits in
835 situations where only 12 of them are correct. Example problem
836 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
837 long time.)
838
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000839- Issue #1580: On most platforms, use a 'short' float repr: for a
840 finite float x, repr(x) now outputs a string based on the shortest
841 sequence of decimal digits that rounds to x. Previous behaviour was
842 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000843 Another minor difference is that the new repr switches to
844 exponential notation at 1e16 instead of the previous 1e17; this
845 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000846
847 There's a new sys attribute sys.float_repr_style, which takes
848 the value 'short' to indicate that we're using short float repr,
849 and 'legacy' if the short float repr isn't available for one
850 reason or another.
851
852 The float repr change involves incorporating David Gay's 'perfect
853 rounding' code into the Python core (it's in Python/dtoa.c). As a
854 secondary consequence, all string-to-float and float-to-string
855 conversions (including all float formatting operations) will be
856 correctly rounded on these platforms.
857
858 See issue 1580 discussions for details of platforms for which
859 this change does not apply.
860
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000861- Issue #5759: float() didn't call __float__ on str subclasses.
862
Georg Brandlabc38772009-04-12 15:51:51 +0000863- The string.maketrans() function is deprecated; there is a new static method
864 maketrans() on the bytes and bytearray classes. This removes confusion about
865 the types string.maketrans() is supposed to work with, and mirrors the
866 methods available on the str class.
867
R. David Murraydc6da8a2009-04-09 22:16:43 +0000868- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
869 its clarity and its speed.
870
Matthias Klose091c7b12009-04-07 13:24:27 +0000871- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
872 to avoid compiler warnings.
873
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000874- Issue #3739: The unicode-internal encoder now reports the number of characters
875 consumed like any other encoder (instead of the number of bytes).

890
Vinay Sajipaffbd872009-06-11 10:11:47 +0000891- Issue #5940: distutils.command.build_clib.check_library_list was not doing

1033 untrackable objects are not tracked by the garbage collector. This can
1034 reduce the size of collections and therefore the garbage collection overhead
1035 on long-running programs, depending on their particular use of datatypes.

1215 collecting the oldest generation) so that allocating lots of objects without
1216 destroying them does not show quadratic performance. Based on a proposal by
1217 Martin von Löwis at
1218 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1219
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001220- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001221 having been closed (for instance, a read() call could return some
1222 previously buffered data). Patch by Dmitry Vasiliev.
1223
Antoine Pitrou05608432009-01-09 18:53:14 +00001224- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1225 flag to work properly. Furthermore, when specifying -u, the text stdout
1226 and stderr streams have line-by-line buffering enabled (the default being
1227 to buffer arbitrary chunks of data).
1228
Raymond Hettinger35631532009-01-09 03:58:09 +00001229- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1230 instead of ints (reducing its size from 4 to 8 times thereby reducing
1231 Python's overall memory).
1232
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001233- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1234 an existing .py counterpart, override the co_filename attributes of all
1235 code objects if the original filename is obsolete (which can happen if the
1236 file has been renamed, moved, or if it is accessed through different paths).
1237 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1238
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001239- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1240 one byte. Also fixes the meaning of len() so that it returns the number of
1241 items, rather than the size in bytes.
1242
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001243- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1244
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001245- Issue #4747: When the terminal does not use utf-8, executing a script with
1246 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1247
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001248- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001249 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001250
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001251- Issue #3680: Reference cycles created through a dict, set or deque iterator
1252 did not get collected.
1253
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001254- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1255 where the tp_hash and tp_dict slots are both NULL.
1256
Georg Brandlccc47b62008-12-28 11:44:14 +00001257- Issue #4759: None is now allowed as the first argument of
1258 bytearray.translate(). It was always allowed for bytes.translate().
1259
Skip Montanaro80072cb2008-12-23 03:51:14 +00001260- Added test case to ensure attempts to read from a file opened for writing
1261 fail.
1262
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001263- Issue #3106: Speedup some comparisons (str/str and int/int).
1264
Antoine Pitrouf289ae62008-12-18 11:06:25 +00001265- Issue #2183: Simplify and optimize bytecode for list, dict and set
1266 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1267
Antoine Pitrou621601a2008-12-17 23:18:19 +00001268- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1269 print elapsed times, not only when some objects are uncollectable /
1270 unreachable. Original patch by Neil Schemenauer.
1271
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001272- Issue #3439: Add a bit_length method to int.
1273
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001274- Issue #2173: When getting device encoding, check that return value of
1275 nl_langinfo is not the empty string. This was causing silent build
1276 failures on OS X.
1277
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001278- Issue #4597: Fixed several opcodes that weren't always propagating
1279 exceptions.
1280
1281- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001282 context manager returns a value that cannot be converted to a bool.
1283
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001284- Issue #4445: Replace "sizeof(PyBytesObject)" with
1285 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1286 bytes instances. On a typical machine this saves 3 bytes of memory
1287 (on average) per allocation of a bytes instance.
1288
Christian Heimesa872de52008-12-05 08:26:55 +00001289- Issue #4533: File read operation was dreadfully slow due to a slowly
1290 growing read buffer. Fixed by using the same growth rate algorithm as
1291 Python 2.x.
1292
Antoine Pitrou5504e892008-12-06 21:27:53 +00001293- Issue #4509: Various issues surrounding resize of bytearray objects to
1294 which there are buffer exports (e.g. memoryview instances).
1295
Georg Brandlf9734072008-12-07 15:30:06 +00001296- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1297 method on file objects with closefd=False. The file descriptor is still
1298 kept open but the file object behaves like a closed file. The ``FileIO``
1299 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00001301- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1302 larger than 1.

1307
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001308- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1309 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1310 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1311 of using the replace error handler in PyUnicode_DecodeUTF8().

1632 do an explicit seek to the end of file (so that e.g. tell() returns the
