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

452 the road because the internally cached encoders and decoders would point
453 to empty global variables.

619Core and Builtins
620-----------------
621
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000622- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
623 of the command line.
624
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000625- Issue #6012: Add cleanup support to O& argument parsing.
626
Eric Smith41669ca2009-05-23 14:23:22 +0000627- Issue #6089: Fixed str.format with certain invalid field specifiers
628 that would raise SystemError.
629
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000630- Issue #5982: staticmethod and classmethod now expose the wrapped
631 function with __func__.
632
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000633- Added support for multiple context managers in the same with-statement.
634 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000635
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000636- Issue #5829: complex("1e500") no longer raises OverflowError. This
637 makes it consistent with float("1e500") and interpretation of real
638 and imaginary literals.
639
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000640- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
641
R. David Murraydd226ea2009-05-13 12:27:21 +0000642- Issue #5994: the marshal module now has docstrings.
643
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000644- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
645 (1) inf and nan strings with trailing whitespace were incorrectly
646 rejected; (2) parsing of strings representing infinities and nans
647 was locale aware; and (3) the interpretation of fromhex('-nan')
648 didn't match that of float('-nan').

651-------
652
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000653- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
654

656
R. David Murray1f1b9d32009-05-27 20:56:59 +0000657- Issue #6121: pydoc now ignores leading and trailing spaces in the
658 argument to the 'help' function.
659
Georg Brandlfaf41492009-05-26 18:31:11 +0000660- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
661 arguments for strings with a space in them.
662
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000663- collections.namedtuple() was not working with the following field
664 names: cls, self, tuple, itemgetter, and property.
665
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000666- In unittest, using a skipping decorator on a class is now equivalent to
667 skipping every test on the class. The ClassTestSuite class has been removed.
668
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000669- Issue #6050: Don't fail extracting a directory from a zipfile if
670 the directory already exists.
671
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000672- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
673 than an int, which makes some operations possible under 64-bit Linux (e.g.
674 DN_MULTISHOT with F_NOTIFY).
675
Antoine Pitrou716c4442009-05-23 19:04:03 +0000676- Issue #5761: Add the name of the underlying file to the repr() of various

678
R. David Murraycaa27b72009-05-23 18:49:56 +0000679- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
680 by Musashi Tamura, tests by Marcin Bachry.
681
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000682- Issue #1983: Fix functions taking or returning a process identifier to use
683 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
684 a process identifier type wider than the standard C integer type.
685
R. David Murray87e20742009-05-23 01:30:26 +0000686- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
687 Patch by Farhan Ahmad, test by Marcin Bachry.
688
Antoine Pitrou6e610062009-05-15 17:04:50 +0000689- Issue #2116: Weak references and weak dictionaries now support copy()ing and
690 deepcopy()ing.
691
Antoine Pitrouc1d09362009-05-15 12:15:51 +0000692- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.

Antoine Pitrou2ca24f02009-05-14 21:30:46 +0000696- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
697
Antoine Pitroue4501852009-05-14 18:55:55 +0000698- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
699 library. This means, for example, that opening an UTF-16 text file in
700 append mode doesn't add a BOM at the end of the file if the file isn't
701 empty.
702
R. David Murray74b89242009-05-13 17:33:03 +0000703- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
704 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
705 corrects a pydoc regression.
706
R. David Murray99352742009-05-07 18:24:38 +0000707- Issue 5955: aifc's close method did not close the file it wrapped,
708 now it does. This also means getfp method now returns the real fp.
709
Benjamin Peterson932073a2009-05-23 16:14:33 +0000710Installation
711------------
712
713- Issue #6047: fullinstall has been removed because Python 3's executable will
714 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +0000715
Ronald Oussorenbe7149e2009-05-26 21:39:08 +0000716- Lib/smtpd.py is no longer installed as a script.

Benjamin Peterson3dc22e82009-05-23 17:09:43 +0000729
Antoine Pitrou20327222009-05-24 20:39:11 +0000730Build
731-----
732
733- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file
734 and a python3.pc symlink in the $(LIBDIR)/pkgconfig directory. Patch by
735 Clinton Roy.
736
Brett Cannon1262e7c2009-05-11 01:47:11 +0000737Tests
738-----
739
740- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
741 tests on darwin even when the OS was installed on a case-sensitive
742 filesystem. Also fixed tests that should not be run when
743 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000746What's New in Python 3.1 beta 1?
747================================
748
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000749*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000750
751Core and Builtins
752-----------------
753
Mark Dickinson865e01a2009-05-07 16:37:01 +0000754- Issue #5914: Add new C API function PyOS_string_to_double, and
755 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
756
Eric Smith741191f2009-05-06 13:08:15 +0000757- Issue #3382: float.__format__, complex.__format__, and %-formatting
758 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
759 affects nan -> NAN and inf -> INF.
760
Mark Hammond5a607a32009-05-06 08:04:54 +0000761- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
762 in all operations, including splitdrive, split, etc. splitunc() now issues
763 a PendingDeprecation warning.
764
Eric Smith63376222009-05-05 14:04:18 +0000765- Issue #5920: For float.__format__, change the behavior with the
766 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
767 to be like 'g' but with at least one decimal point and with a
768 default precision of 12. Previously, the behavior the same but with
769 a default precision of 6. This more closely matches str(), and
770 reduces surprises when adding alignment flags to the empty
771 presentation type. This also affects the new complex.__format__ in
772 the same way.
773
Martin v. Löwis011e8422009-05-05 04:43:17 +0000774- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
775
R. David Murrayb18500d2009-05-04 22:59:07 +0000776- Issue #5890: in subclasses of 'property' the __doc__ attribute was
777 shadowed by classtype's, even if it was None. property now
778 inserts the __doc__ into the subclass instance __dict__.
779
Antoine Pitrou244651a2009-05-04 18:56:13 +0000780- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
781 sequences. Patch by Nick Barnes and Victor Stinner.
782
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000783- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000784
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000785- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
786 received a new method, detach(). detach() disconnects the underlying stream
787 from the buffer or text IO and returns it.
788
Mark Dickinson33841c32009-05-01 15:37:04 +0000789- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
790 floats with absolute value over 1e50. Also remove length
791 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
792 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000793
Eric Smith741191f2009-05-06 13:08:15 +0000794- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000795 format(complex(1, 2./3), '.5') now produces a sensible result.
796
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000797- Issue #5864: Fix empty format code formatting for floats so that it
798 never gives more than the requested number of significant digits.
799
Eric Smith6dc46f52009-04-27 20:39:49 +0000800- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
801 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
802
Eric Smithcc32a112009-04-26 21:35:14 +0000803- Issue #5835: Deprecate PyOS_ascii_formatd.
804
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000805- Issue #4971: Fix titlecase for characters that are their own
806 titlecase, but not their own uppercase.
807
Benjamin Peterson193152c2009-04-25 01:08:45 +0000808- Issue #5283: Setting __class__ in __del__ caused a segfault.
809
Mark Dickinsonad476da2009-04-23 19:14:16 +0000810- Issue #5816: complex(repr(z)) now recovers z exactly, even when
811 z involves nans, infs or negative zeros.
812
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000813- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000814
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000815- Issue #1869 (and many duplicates): make round(x, n) correctly
816 rounded for a float x, by using the decimal <-> binary conversions
817 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
818 consistently agrees with format(x, '.2f').
819
Benjamin Petersonae937c02009-04-18 20:54:08 +0000820- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
821 some builtin types.
822
Eric Smith0923d1d2009-04-16 20:16:10 +0000823- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
824
Eric Smith35e84722009-04-16 20:21:28 +0000825- Issue #5515: str.format() type 'n' combined with commas and leading
826 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000827
828- Implement PEP 378, Format Specifier for Thousands Separator, for
829 floats.
830
Mark Dickinson3370cce2009-04-17 22:40:53 +0000831- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000832 1e11, not 1e12. This avoids printing 13 significant digits in
833 situations where only 12 of them are correct. Example problem
834 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
835 long time.)
836
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000837- Issue #1580: On most platforms, use a 'short' float repr: for a
838 finite float x, repr(x) now outputs a string based on the shortest
839 sequence of decimal digits that rounds to x. Previous behaviour was
840 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000841 Another minor difference is that the new repr switches to
842 exponential notation at 1e16 instead of the previous 1e17; this
843 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000844
845 There's a new sys attribute sys.float_repr_style, which takes
846 the value 'short' to indicate that we're using short float repr,
847 and 'legacy' if the short float repr isn't available for one
848 reason or another.
849
850 The float repr change involves incorporating David Gay's 'perfect
851 rounding' code into the Python core (it's in Python/dtoa.c). As a
852 secondary consequence, all string-to-float and float-to-string
853 conversions (including all float formatting operations) will be
854 correctly rounded on these platforms.
855
856 See issue 1580 discussions for details of platforms for which
857 this change does not apply.
858
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000859- Issue #5759: float() didn't call __float__ on str subclasses.
860
Georg Brandlabc38772009-04-12 15:51:51 +0000861- The string.maketrans() function is deprecated; there is a new static method
862 maketrans() on the bytes and bytearray classes. This removes confusion about
863 the types string.maketrans() is supposed to work with, and mirrors the
864 methods available on the str class.
865
R. David Murraydc6da8a2009-04-09 22:16:43 +0000866- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
867 its clarity and its speed.
868
Matthias Klose091c7b12009-04-07 13:24:27 +0000869- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
870 to avoid compiler warnings.
871
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000872- Issue #3739: The unicode-internal encoder now reports the number of characters
873 consumed like any other encoder (instead of the number of bytes).
874

888
Vinay Sajipaffbd872009-06-11 10:11:47 +0000889- Issue #5940: distutils.command.build_clib.check_library_list was not doing
Tarek Ziadédd9f65f2009-05-06 07:26:24 +0000890 the right type checkings anymore.
891
Thomas Heller00cfc372009-05-05 19:04:40 +0000892- Issue #4875: On win32, ctypes.util.find_library does no longer

1031 untrackable objects are not tracked by the garbage collector. This can
1032 reduce the size of collections and therefore the garbage collection overhead
1033 on long-running programs, depending on their particular use of datatypes.

1104 forever on incomplete input. That caused tarfile.open() to hang when used
1105 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1106 partial bzip2 compressed data.

Vinay Sajip6268cbc2009-01-21 00:19:28 +00001218- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001219 having been closed (for instance, a read() call could return some
1220 previously buffered data). Patch by Dmitry Vasiliev.
1221
Antoine Pitrou05608432009-01-09 18:53:14 +00001222- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1223 flag to work properly. Furthermore, when specifying -u, the text stdout
1224 and stderr streams have line-by-line buffering enabled (the default being
1225 to buffer arbitrary chunks of data).
1226
Raymond Hettinger35631532009-01-09 03:58:09 +00001227- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1228 instead of ints (reducing its size from 4 to 8 times thereby reducing
1229 Python's overall memory).
1230
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001231- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1232 an existing .py counterpart, override the co_filename attributes of all
1233 code objects if the original filename is obsolete (which can happen if the
1234 file has been renamed, moved, or if it is accessed through different paths).
1235 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1236
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001237- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1238 one byte. Also fixes the meaning of len() so that it returns the number of
1239 items, rather than the size in bytes.
1240
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001241- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1242
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001243- Issue #4747: When the terminal does not use utf-8, executing a script with
1244 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1245
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001246- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001247 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001248
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001249- Issue #3680: Reference cycles created through a dict, set or deque iterator
1250 did not get collected.
1251
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001252- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1253 where the tp_hash and tp_dict slots are both NULL.
1254
Georg Brandlccc47b62008-12-28 11:44:14 +00001255- Issue #4759: None is now allowed as the first argument of
1256 bytearray.translate(). It was always allowed for bytes.translate().
1257
Skip Montanaro80072cb2008-12-23 03:51:14 +00001258- Added test case to ensure attempts to read from a file opened for writing
1259 fail.
1260
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001261- Issue #3106: Speedup some comparisons (str/str and int/int).
1262
Antoine Pitrouf289ae62008-12-18 11:06:25 +00001263- Issue #2183: Simplify and optimize bytecode for list, dict and set
1264 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1265
Antoine Pitrou621601a2008-12-17 23:18:19 +00001266- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1267 print elapsed times, not only when some objects are uncollectable /
1268 unreachable. Original patch by Neil Schemenauer.
1269
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001270- Issue #3439: Add a bit_length method to int.
1271
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001272- Issue #2173: When getting device encoding, check that return value of
1273 nl_langinfo is not the empty string. This was causing silent build
1274 failures on OS X.
1275
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001276- Issue #4597: Fixed several opcodes that weren't always propagating
1277 exceptions.
1278
1279- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001280 context manager returns a value that cannot be converted to a bool.
1281
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001282- Issue #4445: Replace "sizeof(PyBytesObject)" with
1283 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1284 bytes instances. On a typical machine this saves 3 bytes of memory
1285 (on average) per allocation of a bytes instance.
1286
Christian Heimesa872de52008-12-05 08:26:55 +00001287- Issue #4533: File read operation was dreadfully slow due to a slowly
1288 growing read buffer. Fixed by using the same growth rate algorithm as
1289 Python 2.x.
1290
Antoine Pitrou5504e892008-12-06 21:27:53 +00001291- Issue #4509: Various issues surrounding resize of bytearray objects to
1292 which there are buffer exports (e.g. memoryview instances).
1293
Georg Brandlf9734072008-12-07 15:30:06 +00001294- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1295 method on file objects with closefd=False. The file descriptor is still
1296 kept open but the file object behaves like a closed file. The ``FileIO``
1297 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001298
Antoine Pitroubc420402008-12-07 20:14:49 +00001299- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1300 larger than 1.

1305
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001306- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1307 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1308 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1309 of using the replace error handler in PyUnicode_DecodeUTF8().
