316 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
317 Previous versions returned a single u'\ufffd'.

758 Decimal operation raises multiple signals and more than one of those

760 the signals should be handled. In many cases this order wasn't
761 being followed, leading to the wrong Python exception being raised.

792 witnessed in test_httpservers.
793
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000794- Issue #8524: When creating an SSL socket, the timeout value of the
795 original socket wasn't retained (instead, a socket with a positive timeout
796 would be turned into a non-blocking SSL socket).
797
Antoine Pitrouec146182010-04-24 21:30:20 +0000798- Issue #5103: SSL handshake would ignore the socket timeout and block
799 indefinitely if the other end didn't respond.
800
801- The do_handshake() method of SSL objects now adjusts the blocking mode of
802 the SSL structure if necessary (as other methods already do).
803
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000804- Issue #8108: Fix the unwrap() method of SSL objects when the socket has

806 wanting to continue using the socket in clear-text mode, by disabling
807 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

1809
Eric Smith41669ca2009-05-23 14:23:22 +00001810- Issue #6089: Fixed str.format with certain invalid field specifiers
1811 that would raise SystemError.
1812
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001813- Issue #5982: staticmethod and classmethod now expose the wrapped
1814 function with __func__.
1815
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001816- Added support for multiple context managers in the same with-statement.
1817 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001819- Issue #5829: complex("1e500") no longer raises OverflowError. This
1820 makes it consistent with float("1e500") and interpretation of real
1821 and imaginary literals.
1822
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001823- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001827- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1828 (1) inf and nan strings with trailing whitespace were incorrectly
1829 rejected; (2) parsing of strings representing infinities and nans
1830 was locale aware; and (3) the interpretation of fromhex('-nan')
1831 didn't match that of float('-nan').

Martin v. Löwisb6a748b2009-05-29 15:23:17 +00001836- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
1837
R. David Murrayfb123912009-05-28 18:19:00 +00001838- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
1839
R. David Murray1f1b9d32009-05-27 20:56:59 +00001840- Issue #6121: pydoc now ignores leading and trailing spaces in the

1845
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001846- collections.namedtuple() was not working with the following field
1847 names: cls, self, tuple, itemgetter, and property.
1848
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001849- In unittest, using a skipping decorator on a class is now equivalent to
1850 skipping every test on the class. The ClassTestSuite class has been removed.
1851
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001852- Issue #6050: Don't fail extracting a directory from a zipfile if
1853 the directory already exists.
1854
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001855- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1856 than an int, which makes some operations possible under 64-bit Linux (e.g.
1857 DN_MULTISHOT with F_NOTIFY).
1858
Antoine Pitrou716c4442009-05-23 19:04:03 +00001859- Issue #5761: Add the name of the underlying file to the repr() of various
1860 IO objects.
1861
R. David Murraycaa27b72009-05-23 18:49:56 +00001862- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1863 by Musashi Tamura, tests by Marcin Bachry.
1864
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001865- Issue #1983: Fix functions taking or returning a process identifier to use
1866 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1867 a process identifier type wider than the standard C integer type.
1868
R. David Murray87e20742009-05-23 01:30:26 +00001869- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1880
Antoine Pitroue4501852009-05-14 18:55:55 +00001881- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1882 library. This means, for example, that opening an UTF-16 text file in
1883 append mode doesn't add a BOM at the end of the file if the file isn't
1884 empty.
1885
R. David Murray74b89242009-05-13 17:33:03 +00001886- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1887 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1888 corrects a pydoc regression.
1889
Georg Brandl442d3b32010-08-01 22:33:12 +00001890- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00001891 now it does. This also means getfp method now returns the real fp.

1894------------
1895
1896- Issue #6047: fullinstall has been removed because Python 3's executable will
1897 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001898
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00001899- Lib/smtpd.py is no longer installed as a script.

1922
Georg Brandl442d3b32010-08-01 22:33:12 +00001923- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00001924 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001929What's New in Python 3.1 beta 1?
1930================================
1931
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001932*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001933
1934Core and Builtins
1935-----------------
1936
Mark Dickinson865e01a2009-05-07 16:37:01 +00001937- Issue #5914: Add new C API function PyOS_string_to_double, and
1938 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1939
Eric Smith741191f2009-05-06 13:08:15 +00001940- Issue #3382: float.__format__, complex.__format__, and %-formatting
1941 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1942 affects nan -> NAN and inf -> INF.
1943
Mark Hammond5a607a32009-05-06 08:04:54 +00001944- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1945 in all operations, including splitdrive, split, etc. splitunc() now issues
1946 a PendingDeprecation warning.
1947
Eric Smith63376222009-05-05 14:04:18 +00001948- Issue #5920: For float.__format__, change the behavior with the
1949 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1950 to be like 'g' but with at least one decimal point and with a
1951 default precision of 12. Previously, the behavior the same but with
1952 a default precision of 6. This more closely matches str(), and
1953 reduces surprises when adding alignment flags to the empty
1954 presentation type. This also affects the new complex.__format__ in
1955 the same way.
1956
Martin v. Löwis011e8422009-05-05 04:43:17 +00001957- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1958
R. David Murrayb18500d2009-05-04 22:59:07 +00001959- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1960 shadowed by classtype's, even if it was None. property now
1961 inserts the __doc__ into the subclass instance __dict__.
1962
Antoine Pitrou244651a2009-05-04 18:56:13 +00001963- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1964 sequences. Patch by Nick Barnes and Victor Stinner.
1965
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001966- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001967
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001968- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1969 received a new method, detach(). detach() disconnects the underlying stream
1970 from the buffer or text IO and returns it.
1971
Mark Dickinson33841c32009-05-01 15:37:04 +00001972- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1973 floats with absolute value over 1e50. Also remove length
1974 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1975 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001976
Eric Smith741191f2009-05-06 13:08:15 +00001977- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001978 format(complex(1, 2./3), '.5') now produces a sensible result.
1979
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001980- Issue #5864: Fix empty format code formatting for floats so that it
1981 never gives more than the requested number of significant digits.
1982
Eric Smith6dc46f52009-04-27 20:39:49 +00001983- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1984 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1985
Eric Smithcc32a112009-04-26 21:35:14 +00001986- Issue #5835: Deprecate PyOS_ascii_formatd.
1987
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001988- Issue #4971: Fix titlecase for characters that are their own
1989 titlecase, but not their own uppercase.
1990
Benjamin Peterson193152c2009-04-25 01:08:45 +00001991- Issue #5283: Setting __class__ in __del__ caused a segfault.
1992
Mark Dickinsonad476da2009-04-23 19:14:16 +00001993- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1994 z involves nans, infs or negative zeros.
1995
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001996- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001997
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001998- Issue #1869 (and many duplicates): make round(x, n) correctly
1999 rounded for a float x, by using the decimal <-> binary conversions
2000 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2001 consistently agrees with format(x, '.2f').
2002
Benjamin Petersonae937c02009-04-18 20:54:08 +00002003- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2004 some builtin types.
2005
Eric Smith0923d1d2009-04-16 20:16:10 +00002006- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2007
Eric Smith35e84722009-04-16 20:21:28 +00002008- Issue #5515: str.format() type 'n' combined with commas and leading
2009 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002010
2011- Implement PEP 378, Format Specifier for Thousands Separator, for
2012 floats.
2013
Mark Dickinson3370cce2009-04-17 22:40:53 +00002014- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002015 1e11, not 1e12. This avoids printing 13 significant digits in
2016 situations where only 12 of them are correct. Example problem
2017 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2018 long time.)
2019
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002020- Issue #1580: On most platforms, use a 'short' float repr: for a
2021 finite float x, repr(x) now outputs a string based on the shortest
2022 sequence of decimal digits that rounds to x. Previous behaviour was
2023 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002024 Another minor difference is that the new repr switches to
2025 exponential notation at 1e16 instead of the previous 1e17; this
2026 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002027
2028 There's a new sys attribute sys.float_repr_style, which takes
2029 the value 'short' to indicate that we're using short float repr,
2030 and 'legacy' if the short float repr isn't available for one
2031 reason or another.
2032
2033 The float repr change involves incorporating David Gay's 'perfect
2034 rounding' code into the Python core (it's in Python/dtoa.c). As a
2035 secondary consequence, all string-to-float and float-to-string
2036 conversions (including all float formatting operations) will be
2037 correctly rounded on these platforms.

Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002040 this change does not apply.

2043
Georg Brandlabc38772009-04-12 15:51:51 +00002044- The string.maketrans() function is deprecated; there is a new static method
2045 maketrans() on the bytes and bytearray classes. This removes confusion about
2046 the types string.maketrans() is supposed to work with, and mirrors the
2047 methods available on the str class.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00002352- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002353 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00002355- Issue #4707: round(x, n) now returns an integer if x is an integer.
2356 Previously it returned a float.
2357
Antoine Pitroub52ec782009-01-25 16:34:23 +00002358- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2359 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2360 evaluation loop is compiled with a new dispatch mechanism which gives
2361 speedups of up to 20%, depending on the system, on various benchmarks.

2372
Mark Dickinson8055afd2009-01-17 10:04:45 +00002373- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2374 type to (void *).
2375
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002376- Issue #4935: The overflow checking code in the expandtabs() method common
2377 to str, bytes and bytearray could be optimized away by the compiler, letting
2378 the interpreter segfault instead of raising an error.
2379
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002380- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2381 __next__ method.
2382
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002383- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2384 function no longer attempt to call the __long__ slot to convert an object
2385 to an integer. Only the __int__ and __trunc__ slots are examined.

2390
Antoine Pitrouab868312009-01-10 15:40:25 +00002391- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2392 common cases are optimized thanks to a dedicated fast path and a moderate
2393 amount of loop unrolling.
2394
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002395- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2396 collecting the oldest generation) so that allocating lots of objects without
2397 destroying them does not show quadratic performance. Based on a proposal by
2398 Martin von Löwis at
2399 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2400
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002401- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002402 having been closed (for instance, a read() call could return some
2403 previously buffered data). Patch by Dmitry Vasiliev.
2404
Antoine Pitrou05608432009-01-09 18:53:14 +00002405- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2406 flag to work properly. Furthermore, when specifying -u, the text stdout
2407 and stderr streams have line-by-line buffering enabled (the default being
2408 to buffer arbitrary chunks of data).
2409
Raymond Hettinger35631532009-01-09 03:58:09 +00002410- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2411 instead of ints (reducing its size from 4 to 8 times thereby reducing
2412 Python's overall memory).
2413
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002414- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2415 an existing .py counterpart, override the co_filename attributes of all
2416 code objects if the original filename is obsolete (which can happen if the
2417 file has been renamed, moved, or if it is accessed through different paths).
2418 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2419
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002420- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2421 one byte. Also fixes the meaning of len() so that it returns the number of
2422 items, rather than the size in bytes.
2423
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002424- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2425
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002426- Issue #4747: When the terminal does not use utf-8, executing a script with
2427 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2428

2437
Georg Brandlccc47b62008-12-28 11:44:14 +00002438- Issue #4759: None is now allowed as the first argument of

2440
Skip Montanaro80072cb2008-12-23 03:51:14 +00002441- Added test case to ensure attempts to read from a file opened for writing
2442 fail.

2454
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002455- Issue #2173: When getting device encoding, check that return value of
2456 nl_langinfo is not the empty string. This was causing silent build
2457 failures on OS X.
2458
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002459- Issue #4597: Fixed several opcodes that weren't always propagating
2460 exceptions.
2461
2462- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002463 context manager returns a value that cannot be converted to a bool.
2464
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002465- Issue #4445: Replace "sizeof(PyBytesObject)" with
2466 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2467 bytes instances. On a typical machine this saves 3 bytes of memory
2468 (on average) per allocation of a bytes instance.
2469
Christian Heimesa872de52008-12-05 08:26:55 +00002470- Issue #4533: File read operation was dreadfully slow due to a slowly
2471 growing read buffer. Fixed by using the same growth rate algorithm as
2472 Python 2.x.
2473
Antoine Pitrou5504e892008-12-06 21:27:53 +00002474- Issue #4509: Various issues surrounding resize of bytearray objects to
2475 which there are buffer exports (e.g. memoryview instances).
2476
Georg Brandlf9734072008-12-07 15:30:06 +00002477- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2478 method on file objects with closefd=False. The file descriptor is still
2479 kept open but the file object behaves like a closed file. The ``FileIO``
2480 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00002489- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2490 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2491 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2492 of using the replace error handler in PyUnicode_DecodeUTF8().
