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

212 reading from stdin so that existing input does not confuse it and
213 lead to incorrect entry or an IOError. It also properly flushes it
214 afterwards to avoid the terminal echoing the input afterwards on
215 OSes such as Solaris.
216
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000217- Issue #7233: Fix a number of two-argument Decimal methods to make

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

445 the encodings package, which would make other tests fail further down
446 the road because the internally cached encoders and decoders would point
447 to empty global variables.
448
Antoine Pitrou941ee882009-11-11 20:59:38 +0000449- Issue #7295: Do not use a hardcoded file name in test_tarfile.

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

613Core and Builtins
614-----------------
615
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000616- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
617 of the command line.
618
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000619- Issue #6012: Add cleanup support to O& argument parsing.
620
Eric Smith41669ca2009-05-23 14:23:22 +0000621- Issue #6089: Fixed str.format with certain invalid field specifiers
622 that would raise SystemError.
623
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000624- Issue #5982: staticmethod and classmethod now expose the wrapped
625 function with __func__.
626
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000627- Added support for multiple context managers in the same with-statement.
628 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000629
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000630- Issue #5829: complex("1e500") no longer raises OverflowError. This
631 makes it consistent with float("1e500") and interpretation of real
632 and imaginary literals.
633
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000634- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
635
R. David Murraydd226ea2009-05-13 12:27:21 +0000636- Issue #5994: the marshal module now has docstrings.
637
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000638- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
639 (1) inf and nan strings with trailing whitespace were incorrectly
640 rejected; (2) parsing of strings representing infinities and nans
641 was locale aware; and (3) the interpretation of fromhex('-nan')
642 didn't match that of float('-nan').

645-------
646
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000647- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
648
R. David Murrayfb123912009-05-28 18:19:00 +0000649- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
650
R. David Murray1f1b9d32009-05-27 20:56:59 +0000651- Issue #6121: pydoc now ignores leading and trailing spaces in the
652 argument to the 'help' function.
653
Georg Brandlfaf41492009-05-26 18:31:11 +0000654- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
655 arguments for strings with a space in them.
656
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000657- collections.namedtuple() was not working with the following field
658 names: cls, self, tuple, itemgetter, and property.
659
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000660- In unittest, using a skipping decorator on a class is now equivalent to
661 skipping every test on the class. The ClassTestSuite class has been removed.
662
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000663- Issue #6050: Don't fail extracting a directory from a zipfile if
664 the directory already exists.
665
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000666- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
667 than an int, which makes some operations possible under 64-bit Linux (e.g.
668 DN_MULTISHOT with F_NOTIFY).
669
Antoine Pitrou716c4442009-05-23 19:04:03 +0000670- Issue #5761: Add the name of the underlying file to the repr() of various
671 IO objects.
672
R. David Murraycaa27b72009-05-23 18:49:56 +0000673- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
674 by Musashi Tamura, tests by Marcin Bachry.
675
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000676- Issue #1983: Fix functions taking or returning a process identifier to use
677 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
678 a process identifier type wider than the standard C integer type.
679
R. David Murray87e20742009-05-23 01:30:26 +0000680- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
681 Patch by Farhan Ahmad, test by Marcin Bachry.
682
Antoine Pitrou6e610062009-05-15 17:04:50 +0000683- Issue #2116: Weak references and weak dictionaries now support copy()ing and
684 deepcopy()ing.
685
Antoine Pitrouc1d09362009-05-15 12:15:51 +0000686- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.
687
Antoine Pitrou37d1c182009-05-14 21:54:00 +0000688- Issue #5918: Fix a crash in the parser module.
689
Antoine Pitrou2ca24f02009-05-14 21:30:46 +0000690- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
691
Antoine Pitroue4501852009-05-14 18:55:55 +0000692- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
693 library. This means, for example, that opening an UTF-16 text file in
694 append mode doesn't add a BOM at the end of the file if the file isn't
695 empty.
696
R. David Murray74b89242009-05-13 17:33:03 +0000697- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
698 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
699 corrects a pydoc regression.
700
R. David Murray99352742009-05-07 18:24:38 +0000701- Issue 5955: aifc's close method did not close the file it wrapped,
702 now it does. This also means getfp method now returns the real fp.
703
Benjamin Peterson932073a2009-05-23 16:14:33 +0000704Installation
705------------
706
707- Issue #6047: fullinstall has been removed because Python 3's executable will
708 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +0000709
Ronald Oussorenbe7149e2009-05-26 21:39:08 +0000710- Lib/smtpd.py is no longer installed as a script.

Antoine Pitrou20327222009-05-24 20:39:11 +0000724Build
725-----
726
727- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file
728 and a python3.pc symlink in the $(LIBDIR)/pkgconfig directory. Patch by
729 Clinton Roy.
730
Brett Cannon1262e7c2009-05-11 01:47:11 +0000731Tests
732-----
733
734- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
735 tests on darwin even when the OS was installed on a case-sensitive
736 filesystem. Also fixed tests that should not be run when
737 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000740What's New in Python 3.1 beta 1?
741================================

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000744
745Core and Builtins
746-----------------
747
Mark Dickinson865e01a2009-05-07 16:37:01 +0000748- Issue #5914: Add new C API function PyOS_string_to_double, and
749 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
750
Eric Smith741191f2009-05-06 13:08:15 +0000751- Issue #3382: float.__format__, complex.__format__, and %-formatting
752 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
753 affects nan -> NAN and inf -> INF.
754
Mark Hammond5a607a32009-05-06 08:04:54 +0000755- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
756 in all operations, including splitdrive, split, etc. splitunc() now issues
757 a PendingDeprecation warning.
758
Eric Smith63376222009-05-05 14:04:18 +0000759- Issue #5920: For float.__format__, change the behavior with the
760 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
761 to be like 'g' but with at least one decimal point and with a
762 default precision of 12. Previously, the behavior the same but with
763 a default precision of 6. This more closely matches str(), and
764 reduces surprises when adding alignment flags to the empty
765 presentation type. This also affects the new complex.__format__ in
766 the same way.
767
Martin v. Löwis011e8422009-05-05 04:43:17 +0000768- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
769
R. David Murrayb18500d2009-05-04 22:59:07 +0000770- Issue #5890: in subclasses of 'property' the __doc__ attribute was
771 shadowed by classtype's, even if it was None. property now
772 inserts the __doc__ into the subclass instance __dict__.
773
Antoine Pitrou244651a2009-05-04 18:56:13 +0000774- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
775 sequences. Patch by Nick Barnes and Victor Stinner.
776
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000777- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000778
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000779- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
780 received a new method, detach(). detach() disconnects the underlying stream
781 from the buffer or text IO and returns it.
782
Mark Dickinson33841c32009-05-01 15:37:04 +0000783- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
784 floats with absolute value over 1e50. Also remove length
785 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
786 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000787
Eric Smith741191f2009-05-06 13:08:15 +0000788- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000789 format(complex(1, 2./3), '.5') now produces a sensible result.
790
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000791- Issue #5864: Fix empty format code formatting for floats so that it
792 never gives more than the requested number of significant digits.
793
Eric Smith6dc46f52009-04-27 20:39:49 +0000794- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
795 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
796
Eric Smithcc32a112009-04-26 21:35:14 +0000797- Issue #5835: Deprecate PyOS_ascii_formatd.
798
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000799- Issue #4971: Fix titlecase for characters that are their own
800 titlecase, but not their own uppercase.
801
Benjamin Peterson193152c2009-04-25 01:08:45 +0000802- Issue #5283: Setting __class__ in __del__ caused a segfault.
803
Mark Dickinsonad476da2009-04-23 19:14:16 +0000804- Issue #5816: complex(repr(z)) now recovers z exactly, even when
805 z involves nans, infs or negative zeros.
806
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000807- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000808
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000809- Issue #1869 (and many duplicates): make round(x, n) correctly
810 rounded for a float x, by using the decimal <-> binary conversions
811 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
812 consistently agrees with format(x, '.2f').
813
Benjamin Petersonae937c02009-04-18 20:54:08 +0000814- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
815 some builtin types.
816
Eric Smith0923d1d2009-04-16 20:16:10 +0000817- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
818
Eric Smith35e84722009-04-16 20:21:28 +0000819- Issue #5515: str.format() type 'n' combined with commas and leading
820 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000821
822- Implement PEP 378, Format Specifier for Thousands Separator, for
823 floats.
824
Mark Dickinson3370cce2009-04-17 22:40:53 +0000825- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000826 1e11, not 1e12. This avoids printing 13 significant digits in
827 situations where only 12 of them are correct. Example problem
828 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
829 long time.)
830
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000831- Issue #1580: On most platforms, use a 'short' float repr: for a
832 finite float x, repr(x) now outputs a string based on the shortest
833 sequence of decimal digits that rounds to x. Previous behaviour was
834 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000835 Another minor difference is that the new repr switches to
836 exponential notation at 1e16 instead of the previous 1e17; this
837 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000838
839 There's a new sys attribute sys.float_repr_style, which takes
840 the value 'short' to indicate that we're using short float repr,
841 and 'legacy' if the short float repr isn't available for one
842 reason or another.
843
844 The float repr change involves incorporating David Gay's 'perfect
845 rounding' code into the Python core (it's in Python/dtoa.c). As a
846 secondary consequence, all string-to-float and float-to-string
847 conversions (including all float formatting operations) will be
848 correctly rounded on these platforms.
849
850 See issue 1580 discussions for details of platforms for which
851 this change does not apply.
852
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000853- Issue #5759: float() didn't call __float__ on str subclasses.
854
Georg Brandlabc38772009-04-12 15:51:51 +0000855- The string.maketrans() function is deprecated; there is a new static method
856 maketrans() on the bytes and bytearray classes. This removes confusion about
857 the types string.maketrans() is supposed to work with, and mirrors the
858 methods available on the str class.
859
R. David Murraydc6da8a2009-04-09 22:16:43 +0000860- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
861 its clarity and its speed.
862
Matthias Klose091c7b12009-04-07 13:24:27 +0000863- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
864 to avoid compiler warnings.
865
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000866- Issue #3739: The unicode-internal encoder now reports the number of characters
867 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrou8043cf82009-01-09 19:54:29 +00001213 having been closed (for instance, a read() call could return some
1214 previously buffered data). Patch by Dmitry Vasiliev.
1215
Antoine Pitrou05608432009-01-09 18:53:14 +00001216- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1217 flag to work properly. Furthermore, when specifying -u, the text stdout
1218 and stderr streams have line-by-line buffering enabled (the default being
1219 to buffer arbitrary chunks of data).
1220
Raymond Hettinger35631532009-01-09 03:58:09 +00001221- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1222 instead of ints (reducing its size from 4 to 8 times thereby reducing
1223 Python's overall memory).
1224
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001225- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1226 an existing .py counterpart, override the co_filename attributes of all
1227 code objects if the original filename is obsolete (which can happen if the
1228 file has been renamed, moved, or if it is accessed through different paths).
1229 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1230
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001231- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1232 one byte. Also fixes the meaning of len() so that it returns the number of
1233 items, rather than the size in bytes.
1234
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001235- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1236
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001237- Issue #4747: When the terminal does not use utf-8, executing a script with
1238 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1239

Antoine Pitrou7ddda782009-01-01 15:35:33 +00001243- Issue #3680: Reference cycles created through a dict, set or deque iterator
1244 did not get collected.
1245
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001246- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1247 where the tp_hash and tp_dict slots are both NULL.
1248
Georg Brandlccc47b62008-12-28 11:44:14 +00001249- Issue #4759: None is now allowed as the first argument of
1250 bytearray.translate(). It was always allowed for bytes.translate().
1251
Skip Montanaro80072cb2008-12-23 03:51:14 +00001252- Added test case to ensure attempts to read from a file opened for writing
1253 fail.
1254
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001255- Issue #3106: Speedup some comparisons (str/str and int/int).

1259
Antoine Pitrou621601a2008-12-17 23:18:19 +00001260- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1261 print elapsed times, not only when some objects are uncollectable /
1262 unreachable. Original patch by Neil Schemenauer.
1263

1265
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001266- Issue #2173: When getting device encoding, check that return value of
1267 nl_langinfo is not the empty string. This was causing silent build
1268 failures on OS X.
1269
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001270- Issue #4597: Fixed several opcodes that weren't always propagating
1271 exceptions.
1272
1273- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001274 context manager returns a value that cannot be converted to a bool.
1275
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001276- Issue #4445: Replace "sizeof(PyBytesObject)" with
1277 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1278 bytes instances. On a typical machine this saves 3 bytes of memory
1279 (on average) per allocation of a bytes instance.
1280
Christian Heimesa872de52008-12-05 08:26:55 +00001281- Issue #4533: File read operation was dreadfully slow due to a slowly
1282 growing read buffer. Fixed by using the same growth rate algorithm as
1283 Python 2.x.
1284
Antoine Pitrou5504e892008-12-06 21:27:53 +00001285- Issue #4509: Various issues surrounding resize of bytearray objects to
1286 which there are buffer exports (e.g. memoryview instances).
1287
Georg Brandlf9734072008-12-07 15:30:06 +00001288- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1289 method on file objects with closefd=False. The file descriptor is still
1290 kept open but the file object behaves like a closed file. The ``FileIO``
1291 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001292
Antoine Pitroubc420402008-12-07 20:14:49 +00001293- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1299
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001300- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1301 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1302 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1303 of using the replace error handler in PyUnicode_DecodeUTF8().

1624 do an explicit seek to the end of file (so that e.g. tell() returns the
