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

216 reading from stdin so that existing input does not confuse it and
217 lead to incorrect entry or an IOError. It also properly flushes it
218 afterwards to avoid the terminal echoing the input afterwards on
219 OSes such as Solaris.
220
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000221- Issue #7233: Fix a number of two-argument Decimal methods to make

223 fix buggy handling of large arguments (those with coefficient longer
224 than the current precision) in shift and rotate.

450 the road because the internally cached encoders and decoders would point
451 to empty global variables.

617Core and Builtins
618-----------------
619
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000620- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
621 of the command line.
622
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000623- Issue #6012: Add cleanup support to O& argument parsing.
624
Eric Smith41669ca2009-05-23 14:23:22 +0000625- Issue #6089: Fixed str.format with certain invalid field specifiers
626 that would raise SystemError.
627
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000628- Issue #5982: staticmethod and classmethod now expose the wrapped
629 function with __func__.
630
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000631- Added support for multiple context managers in the same with-statement.
632 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000633
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000634- Issue #5829: complex("1e500") no longer raises OverflowError. This
635 makes it consistent with float("1e500") and interpretation of real
636 and imaginary literals.
637
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000638- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
639
R. David Murraydd226ea2009-05-13 12:27:21 +0000640- Issue #5994: the marshal module now has docstrings.
641
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000642- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
643 (1) inf and nan strings with trailing whitespace were incorrectly
644 rejected; (2) parsing of strings representing infinities and nans
645 was locale aware; and (3) the interpretation of fromhex('-nan')
646 didn't match that of float('-nan').

649-------
650
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000651- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
652
R. David Murrayfb123912009-05-28 18:19:00 +0000653- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
654
R. David Murray1f1b9d32009-05-27 20:56:59 +0000655- Issue #6121: pydoc now ignores leading and trailing spaces in the
656 argument to the 'help' function.
657
Georg Brandlfaf41492009-05-26 18:31:11 +0000658- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
659 arguments for strings with a space in them.
660
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000661- collections.namedtuple() was not working with the following field
662 names: cls, self, tuple, itemgetter, and property.
663
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000664- In unittest, using a skipping decorator on a class is now equivalent to
665 skipping every test on the class. The ClassTestSuite class has been removed.
666
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000667- Issue #6050: Don't fail extracting a directory from a zipfile if
668 the directory already exists.
669
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000670- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
671 than an int, which makes some operations possible under 64-bit Linux (e.g.
672 DN_MULTISHOT with F_NOTIFY).
673
Antoine Pitrou716c4442009-05-23 19:04:03 +0000674- Issue #5761: Add the name of the underlying file to the repr() of various

676
R. David Murraycaa27b72009-05-23 18:49:56 +0000677- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
678 by Musashi Tamura, tests by Marcin Bachry.
679
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000680- Issue #1983: Fix functions taking or returning a process identifier to use
681 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
682 a process identifier type wider than the standard C integer type.
683
R. David Murray87e20742009-05-23 01:30:26 +0000684- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
685 Patch by Farhan Ahmad, test by Marcin Bachry.
686
Antoine Pitrou6e610062009-05-15 17:04:50 +0000687- Issue #2116: Weak references and weak dictionaries now support copy()ing and
688 deepcopy()ing.
689
Antoine Pitrouc1d09362009-05-15 12:15:51 +0000690- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.
691
Antoine Pitrou37d1c182009-05-14 21:54:00 +0000692- Issue #5918: Fix a crash in the parser module.
693
Antoine Pitrou2ca24f02009-05-14 21:30:46 +0000694- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
695
Antoine Pitroue4501852009-05-14 18:55:55 +0000696- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
697 library. This means, for example, that opening an UTF-16 text file in
698 append mode doesn't add a BOM at the end of the file if the file isn't
699 empty.
700
R. David Murray74b89242009-05-13 17:33:03 +0000701- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
702 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
703 corrects a pydoc regression.
704
R. David Murray99352742009-05-07 18:24:38 +0000705- Issue 5955: aifc's close method did not close the file it wrapped,
706 now it does. This also means getfp method now returns the real fp.
707
Benjamin Peterson932073a2009-05-23 16:14:33 +0000708Installation
709------------
710
711- Issue #6047: fullinstall has been removed because Python 3's executable will
712 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +0000713
Ronald Oussorenbe7149e2009-05-26 21:39:08 +0000714- Lib/smtpd.py is no longer installed as a script.

726 library instead of as extension modules.
Benjamin Peterson3dc22e82009-05-23 17:09:43 +0000727
Antoine Pitrou20327222009-05-24 20:39:11 +0000728Build
729-----
730
731- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file
732 and a python3.pc symlink in the $(LIBDIR)/pkgconfig directory. Patch by
733 Clinton Roy.
734
Brett Cannon1262e7c2009-05-11 01:47:11 +0000735Tests
736-----
737
738- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
739 tests on darwin even when the OS was installed on a case-sensitive
740 filesystem. Also fixed tests that should not be run when
741 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000744What's New in Python 3.1 beta 1?
745================================
746
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000747*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000748
749Core and Builtins
750-----------------
751
Mark Dickinson865e01a2009-05-07 16:37:01 +0000752- Issue #5914: Add new C API function PyOS_string_to_double, and
753 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
754
Eric Smith741191f2009-05-06 13:08:15 +0000755- Issue #3382: float.__format__, complex.__format__, and %-formatting
756 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
757 affects nan -> NAN and inf -> INF.
758
Mark Hammond5a607a32009-05-06 08:04:54 +0000759- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
760 in all operations, including splitdrive, split, etc. splitunc() now issues
761 a PendingDeprecation warning.
762
Eric Smith63376222009-05-05 14:04:18 +0000763- Issue #5920: For float.__format__, change the behavior with the
764 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
765 to be like 'g' but with at least one decimal point and with a
766 default precision of 12. Previously, the behavior the same but with
767 a default precision of 6. This more closely matches str(), and
768 reduces surprises when adding alignment flags to the empty
769 presentation type. This also affects the new complex.__format__ in
770 the same way.
771
Martin v. Löwis011e8422009-05-05 04:43:17 +0000772- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
773
R. David Murrayb18500d2009-05-04 22:59:07 +0000774- Issue #5890: in subclasses of 'property' the __doc__ attribute was
775 shadowed by classtype's, even if it was None. property now
776 inserts the __doc__ into the subclass instance __dict__.
777
Antoine Pitrou244651a2009-05-04 18:56:13 +0000778- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
779 sequences. Patch by Nick Barnes and Victor Stinner.
780
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000781- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000782
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000783- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
784 received a new method, detach(). detach() disconnects the underlying stream
785 from the buffer or text IO and returns it.
786
Mark Dickinson33841c32009-05-01 15:37:04 +0000787- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
788 floats with absolute value over 1e50. Also remove length
789 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
790 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000791
Eric Smith741191f2009-05-06 13:08:15 +0000792- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000793 format(complex(1, 2./3), '.5') now produces a sensible result.
794
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000795- Issue #5864: Fix empty format code formatting for floats so that it
796 never gives more than the requested number of significant digits.
797
Eric Smith6dc46f52009-04-27 20:39:49 +0000798- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
799 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
800
Eric Smithcc32a112009-04-26 21:35:14 +0000801- Issue #5835: Deprecate PyOS_ascii_formatd.
802
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000803- Issue #4971: Fix titlecase for characters that are their own
804 titlecase, but not their own uppercase.
805
Benjamin Peterson193152c2009-04-25 01:08:45 +0000806- Issue #5283: Setting __class__ in __del__ caused a segfault.
807
Mark Dickinsonad476da2009-04-23 19:14:16 +0000808- Issue #5816: complex(repr(z)) now recovers z exactly, even when
809 z involves nans, infs or negative zeros.
810
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000811- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000812
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000813- Issue #1869 (and many duplicates): make round(x, n) correctly
814 rounded for a float x, by using the decimal <-> binary conversions
815 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
816 consistently agrees with format(x, '.2f').
817
Benjamin Petersonae937c02009-04-18 20:54:08 +0000818- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
819 some builtin types.
820
Eric Smith0923d1d2009-04-16 20:16:10 +0000821- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
822
Eric Smith35e84722009-04-16 20:21:28 +0000823- Issue #5515: str.format() type 'n' combined with commas and leading
824 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000825
826- Implement PEP 378, Format Specifier for Thousands Separator, for
827 floats.
828
Mark Dickinson3370cce2009-04-17 22:40:53 +0000829- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000830 1e11, not 1e12. This avoids printing 13 significant digits in
831 situations where only 12 of them are correct. Example problem
832 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
833 long time.)
834
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000835- Issue #1580: On most platforms, use a 'short' float repr: for a
836 finite float x, repr(x) now outputs a string based on the shortest
837 sequence of decimal digits that rounds to x. Previous behaviour was
838 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000839 Another minor difference is that the new repr switches to
840 exponential notation at 1e16 instead of the previous 1e17; this
841 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000842
843 There's a new sys attribute sys.float_repr_style, which takes
844 the value 'short' to indicate that we're using short float repr,
845 and 'legacy' if the short float repr isn't available for one
846 reason or another.
847
848 The float repr change involves incorporating David Gay's 'perfect
849 rounding' code into the Python core (it's in Python/dtoa.c). As a
850 secondary consequence, all string-to-float and float-to-string
851 conversions (including all float formatting operations) will be
852 correctly rounded on these platforms.
853
854 See issue 1580 discussions for details of platforms for which
855 this change does not apply.
856
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000857- Issue #5759: float() didn't call __float__ on str subclasses.
858
Georg Brandlabc38772009-04-12 15:51:51 +0000859- The string.maketrans() function is deprecated; there is a new static method
860 maketrans() on the bytes and bytearray classes. This removes confusion about
861 the types string.maketrans() is supposed to work with, and mirrors the
862 methods available on the str class.
863
R. David Murraydc6da8a2009-04-09 22:16:43 +0000864- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
865 its clarity and its speed.
866
Matthias Klose091c7b12009-04-07 13:24:27 +0000867- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
868 to avoid compiler warnings.
869
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000870- Issue #3739: The unicode-internal encoder now reports the number of characters
871 consumed like any other encoder (instead of the number of bytes).

886
Vinay Sajipaffbd872009-06-11 10:11:47 +0000887- Issue #5940: distutils.command.build_clib.check_library_list was not doing

1029 untrackable objects are not tracked by the garbage collector. This can
1030 reduce the size of collections and therefore the garbage collection overhead
1031 on long-running programs, depending on their particular use of datatypes.

1102 forever on incomplete input. That caused tarfile.open() to hang when used
1103 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1104 partial bzip2 compressed data.

Vinay Sajip6268cbc2009-01-21 00:19:28 +00001216- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001217 having been closed (for instance, a read() call could return some
1218 previously buffered data). Patch by Dmitry Vasiliev.
1219
Antoine Pitrou05608432009-01-09 18:53:14 +00001220- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1221 flag to work properly. Furthermore, when specifying -u, the text stdout
1222 and stderr streams have line-by-line buffering enabled (the default being
1223 to buffer arbitrary chunks of data).
1224
Raymond Hettinger35631532009-01-09 03:58:09 +00001225- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1226 instead of ints (reducing its size from 4 to 8 times thereby reducing
1227 Python's overall memory).
1228
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001229- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1230 an existing .py counterpart, override the co_filename attributes of all
1231 code objects if the original filename is obsolete (which can happen if the
1232 file has been renamed, moved, or if it is accessed through different paths).
1233 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1234
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001235- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1236 one byte. Also fixes the meaning of len() so that it returns the number of
1237 items, rather than the size in bytes.
1238
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001239- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1240
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001241- Issue #4747: When the terminal does not use utf-8, executing a script with
1242 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1243
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001244- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001245 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001246
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001247- Issue #3680: Reference cycles created through a dict, set or deque iterator
1248 did not get collected.
1249
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001250- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1251 where the tp_hash and tp_dict slots are both NULL.
1252
Georg Brandlccc47b62008-12-28 11:44:14 +00001253- Issue #4759: None is now allowed as the first argument of
1254 bytearray.translate(). It was always allowed for bytes.translate().
1255
Skip Montanaro80072cb2008-12-23 03:51:14 +00001256- Added test case to ensure attempts to read from a file opened for writing
1257 fail.
1258
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001259- Issue #3106: Speedup some comparisons (str/str and int/int).
1260
Antoine Pitrouf289ae62008-12-18 11:06:25 +00001261- Issue #2183: Simplify and optimize bytecode for list, dict and set
1262 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1263
Antoine Pitrou621601a2008-12-17 23:18:19 +00001264- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1265 print elapsed times, not only when some objects are uncollectable /
1266 unreachable. Original patch by Neil Schemenauer.
1267
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001268- Issue #3439: Add a bit_length method to int.
1269
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001270- Issue #2173: When getting device encoding, check that return value of
1271 nl_langinfo is not the empty string. This was causing silent build
1272 failures on OS X.
1273
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001274- Issue #4597: Fixed several opcodes that weren't always propagating
1275 exceptions.
1276
1277- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001278 context manager returns a value that cannot be converted to a bool.
1279
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001280- Issue #4445: Replace "sizeof(PyBytesObject)" with
1281 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1282 bytes instances. On a typical machine this saves 3 bytes of memory
1283 (on average) per allocation of a bytes instance.
1284
Christian Heimesa872de52008-12-05 08:26:55 +00001285- Issue #4533: File read operation was dreadfully slow due to a slowly
1286 growing read buffer. Fixed by using the same growth rate algorithm as
1287 Python 2.x.
1288
Antoine Pitrou5504e892008-12-06 21:27:53 +00001289- Issue #4509: Various issues surrounding resize of bytearray objects to
1290 which there are buffer exports (e.g. memoryview instances).
1291
Georg Brandlf9734072008-12-07 15:30:06 +00001292- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1293 method on file objects with closefd=False. The file descriptor is still
1294 kept open but the file object behaves like a closed file. The ``FileIO``
1295 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001296
Antoine Pitroubc420402008-12-07 20:14:49 +00001297- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1298 larger than 1.

1303
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001304- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1305 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1306 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1307 of using the replace error handler in PyUnicode_DecodeUTF8().

1628 do an explicit seek to the end of file (so that e.g. tell() returns the
