771 witnessed in test_httpservers.
772
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000773- Issue #8524: When creating an SSL socket, the timeout value of the
774 original socket wasn't retained (instead, a socket with a positive timeout
775 would be turned into a non-blocking SSL socket).
776
Antoine Pitrouec146182010-04-24 21:30:20 +0000777- Issue #5103: SSL handshake would ignore the socket timeout and block
778 indefinitely if the other end didn't respond.
779
780- The do_handshake() method of SSL objects now adjusts the blocking mode of
781 the SSL structure if necessary (as other methods already do).
782
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000783- Issue #8108: Fix the unwrap() method of SSL objects when the socket has

1783
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00001784- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
1785 of the command line.
1786
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00001787- Issue #6012: Add cleanup support to O& argument parsing.
1788
Eric Smith41669ca2009-05-23 14:23:22 +00001789- Issue #6089: Fixed str.format with certain invalid field specifiers
1790 that would raise SystemError.
1791
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001792- Issue #5982: staticmethod and classmethod now expose the wrapped
1793 function with __func__.
1794
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001795- Added support for multiple context managers in the same with-statement.
1796 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001798- Issue #5829: complex("1e500") no longer raises OverflowError. This
1799 makes it consistent with float("1e500") and interpretation of real
1800 and imaginary literals.
1801
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001802- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

1805
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001806- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1807 (1) inf and nan strings with trailing whitespace were incorrectly
1808 rejected; (2) parsing of strings representing infinities and nans
1809 was locale aware; and (3) the interpretation of fromhex('-nan')
1810 didn't match that of float('-nan').

1813-------
1814
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00001815- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
1816
R. David Murrayfb123912009-05-28 18:19:00 +00001817- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
1818
R. David Murray1f1b9d32009-05-27 20:56:59 +00001819- Issue #6121: pydoc now ignores leading and trailing spaces in the
1820 argument to the 'help' function.
1821
Georg Brandlfaf41492009-05-26 18:31:11 +00001822- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1823 arguments for strings with a space in them.
1824
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001825- collections.namedtuple() was not working with the following field
1826 names: cls, self, tuple, itemgetter, and property.
1827
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001828- In unittest, using a skipping decorator on a class is now equivalent to
1829 skipping every test on the class. The ClassTestSuite class has been removed.
1830
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001831- Issue #6050: Don't fail extracting a directory from a zipfile if
1832 the directory already exists.
1833
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001834- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1835 than an int, which makes some operations possible under 64-bit Linux (e.g.
1836 DN_MULTISHOT with F_NOTIFY).
1837
Antoine Pitrou716c4442009-05-23 19:04:03 +00001838- Issue #5761: Add the name of the underlying file to the repr() of various
1839 IO objects.
1840
R. David Murraycaa27b72009-05-23 18:49:56 +00001841- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1842 by Musashi Tamura, tests by Marcin Bachry.
1843
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001844- Issue #1983: Fix functions taking or returning a process identifier to use
1845 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1846 a process identifier type wider than the standard C integer type.
1847
R. David Murray87e20742009-05-23 01:30:26 +00001848- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1859
Antoine Pitroue4501852009-05-14 18:55:55 +00001860- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1861 library. This means, for example, that opening an UTF-16 text file in
1862 append mode doesn't add a BOM at the end of the file if the file isn't
1863 empty.
1864
R. David Murray74b89242009-05-13 17:33:03 +00001865- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1866 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1867 corrects a pydoc regression.
1868
Georg Brandl442d3b32010-08-01 22:33:12 +00001869- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00001870 now it does. This also means getfp method now returns the real fp.

1873------------
1874
1875- Issue #6047: fullinstall has been removed because Python 3's executable will
1876 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001877
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00001878- Lib/smtpd.py is no longer installed as a script.

1907
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001908What's New in Python 3.1 beta 1?
1909================================
1910
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001911*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001912
1913Core and Builtins
1914-----------------
1915
Mark Dickinson865e01a2009-05-07 16:37:01 +00001916- Issue #5914: Add new C API function PyOS_string_to_double, and
1917 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1918
Eric Smith741191f2009-05-06 13:08:15 +00001919- Issue #3382: float.__format__, complex.__format__, and %-formatting
1920 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1921 affects nan -> NAN and inf -> INF.
1922
Mark Hammond5a607a32009-05-06 08:04:54 +00001923- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1924 in all operations, including splitdrive, split, etc. splitunc() now issues
1925 a PendingDeprecation warning.
1926
Eric Smith63376222009-05-05 14:04:18 +00001927- Issue #5920: For float.__format__, change the behavior with the
1928 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1929 to be like 'g' but with at least one decimal point and with a
1930 default precision of 12. Previously, the behavior the same but with
1931 a default precision of 6. This more closely matches str(), and
1932 reduces surprises when adding alignment flags to the empty
1933 presentation type. This also affects the new complex.__format__ in
1934 the same way.
1935
Martin v. Löwis011e8422009-05-05 04:43:17 +00001936- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1937
R. David Murrayb18500d2009-05-04 22:59:07 +00001938- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1939 shadowed by classtype's, even if it was None. property now
1940 inserts the __doc__ into the subclass instance __dict__.
1941
Antoine Pitrou244651a2009-05-04 18:56:13 +00001942- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1943 sequences. Patch by Nick Barnes and Victor Stinner.
1944
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001945- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001946
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001947- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1948 received a new method, detach(). detach() disconnects the underlying stream
1949 from the buffer or text IO and returns it.
1950
Mark Dickinson33841c32009-05-01 15:37:04 +00001951- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1952 floats with absolute value over 1e50. Also remove length
1953 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1954 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001955
Eric Smith741191f2009-05-06 13:08:15 +00001956- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001957 format(complex(1, 2./3), '.5') now produces a sensible result.
1958
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001959- Issue #5864: Fix empty format code formatting for floats so that it
1960 never gives more than the requested number of significant digits.
1961
Eric Smith6dc46f52009-04-27 20:39:49 +00001962- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1963 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1964
Eric Smithcc32a112009-04-26 21:35:14 +00001965- Issue #5835: Deprecate PyOS_ascii_formatd.
1966
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001967- Issue #4971: Fix titlecase for characters that are their own
1968 titlecase, but not their own uppercase.
1969
Benjamin Peterson193152c2009-04-25 01:08:45 +00001970- Issue #5283: Setting __class__ in __del__ caused a segfault.
1971
Mark Dickinsonad476da2009-04-23 19:14:16 +00001972- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1973 z involves nans, infs or negative zeros.
1974
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001975- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001976
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001977- Issue #1869 (and many duplicates): make round(x, n) correctly
1978 rounded for a float x, by using the decimal <-> binary conversions
1979 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1980 consistently agrees with format(x, '.2f').
1981
Benjamin Petersonae937c02009-04-18 20:54:08 +00001982- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1983 some builtin types.
1984
Eric Smith0923d1d2009-04-16 20:16:10 +00001985- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1986
Eric Smith35e84722009-04-16 20:21:28 +00001987- Issue #5515: str.format() type 'n' combined with commas and leading
1988 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001989
1990- Implement PEP 378, Format Specifier for Thousands Separator, for
1991 floats.
1992
Mark Dickinson3370cce2009-04-17 22:40:53 +00001993- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001994 1e11, not 1e12. This avoids printing 13 significant digits in
1995 situations where only 12 of them are correct. Example problem
1996 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1997 long time.)
1998
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001999- Issue #1580: On most platforms, use a 'short' float repr: for a
2000 finite float x, repr(x) now outputs a string based on the shortest
2001 sequence of decimal digits that rounds to x. Previous behaviour was
2002 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002003 Another minor difference is that the new repr switches to
2004 exponential notation at 1e16 instead of the previous 1e17; this
2005 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002006
2007 There's a new sys attribute sys.float_repr_style, which takes
2008 the value 'short' to indicate that we're using short float repr,
2009 and 'legacy' if the short float repr isn't available for one
2010 reason or another.
2011
2012 The float repr change involves incorporating David Gay's 'perfect
2013 rounding' code into the Python core (it's in Python/dtoa.c). As a
2014 secondary consequence, all string-to-float and float-to-string
2015 conversions (including all float formatting operations) will be
2016 correctly rounded on these platforms.
2017
Georg Brandl442d3b32010-08-01 22:33:12 +00002018 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002019 this change does not apply.
2020
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002021- Issue #5759: float() didn't call __float__ on str subclasses.
2022
Georg Brandlabc38772009-04-12 15:51:51 +00002023- The string.maketrans() function is deprecated; there is a new static method
2024 maketrans() on the bytes and bytearray classes. This removes confusion about
2025 the types string.maketrans() is supposed to work with, and mirrors the
2026 methods available on the str class.
2027
R. David Murraydc6da8a2009-04-09 22:16:43 +00002028- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Mark Dickinsone94c6792009-02-02 20:36:42 +00002328 the type definition cmpfunc. The tp_compare slot has been renamed
2329 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00002331- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002332 were suppressing all exceptions. These include list() and bytearray().
2333
Mark Dickinson1124e712009-01-28 21:25:58 +00002334- Issue #4707: round(x, n) now returns an integer if x is an integer.
2335 Previously it returned a float.
2336
Antoine Pitroub52ec782009-01-25 16:34:23 +00002337- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2338 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2339 evaluation loop is compiled with a new dispatch mechanism which gives
2340 speedups of up to 20%, depending on the system, on various benchmarks.
2341
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002342- Issue #4874: Most builtin decoders now reject unicode input.

2348
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002349- Issue #4838: When a module is deallocated, free the memory backing the
2350 optional module state data.
2351
Mark Dickinson8055afd2009-01-17 10:04:45 +00002352- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2353 type to (void *).
2354
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002355- Issue #4935: The overflow checking code in the expandtabs() method common
2356 to str, bytes and bytearray could be optimized away by the compiler, letting
2357 the interpreter segfault instead of raising an error.
2358
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002359- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2360 __next__ method.
2361
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002362- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2363 function no longer attempt to call the __long__ slot to convert an object
2364 to an integer. Only the __int__ and __trunc__ slots are examined.

2369
Antoine Pitrouab868312009-01-10 15:40:25 +00002370- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2371 common cases are optimized thanks to a dedicated fast path and a moderate
2372 amount of loop unrolling.
2373
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002374- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2375 collecting the oldest generation) so that allocating lots of objects without
2376 destroying them does not show quadratic performance. Based on a proposal by
2377 Martin von Löwis at
2378 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2379
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002380- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002381 having been closed (for instance, a read() call could return some
2382 previously buffered data). Patch by Dmitry Vasiliev.
2383
Antoine Pitrou05608432009-01-09 18:53:14 +00002384- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2385 flag to work properly. Furthermore, when specifying -u, the text stdout
2386 and stderr streams have line-by-line buffering enabled (the default being
2387 to buffer arbitrary chunks of data).
2388
Raymond Hettinger35631532009-01-09 03:58:09 +00002389- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2390 instead of ints (reducing its size from 4 to 8 times thereby reducing
2391 Python's overall memory).
2392
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002393- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2394 an existing .py counterpart, override the co_filename attributes of all
2395 code objects if the original filename is obsolete (which can happen if the
2396 file has been renamed, moved, or if it is accessed through different paths).
2397 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2398
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002399- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2400 one byte. Also fixes the meaning of len() so that it returns the number of
2401 items, rather than the size in bytes.
2402
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002403- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2404
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002405- Issue #4747: When the terminal does not use utf-8, executing a script with
2406 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2407
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002408- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002409 file with `bytes' filename on Windows.

2412 did not get collected.
2413
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002414- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2415 where the tp_hash and tp_dict slots are both NULL.
2416
Georg Brandlccc47b62008-12-28 11:44:14 +00002417- Issue #4759: None is now allowed as the first argument of
2418 bytearray.translate(). It was always allowed for bytes.translate().
2419
Skip Montanaro80072cb2008-12-23 03:51:14 +00002420- Added test case to ensure attempts to read from a file opened for writing
2421 fail.
2422
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002423- Issue #3106: Speedup some comparisons (str/str and int/int).

2426 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2427
Antoine Pitrou621601a2008-12-17 23:18:19 +00002428- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

2430 unreachable. Original patch by Neil Schemenauer.
2431
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002432- Issue #3439: Add a bit_length method to int.
2433
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002434- Issue #2173: When getting device encoding, check that return value of
2435 nl_langinfo is not the empty string. This was causing silent build
2436 failures on OS X.
2437
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002438- Issue #4597: Fixed several opcodes that weren't always propagating
2439 exceptions.
2440
2441- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002442 context manager returns a value that cannot be converted to a bool.
2443
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002444- Issue #4445: Replace "sizeof(PyBytesObject)" with
2445 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2446 bytes instances. On a typical machine this saves 3 bytes of memory
2447 (on average) per allocation of a bytes instance.
2448
Christian Heimesa872de52008-12-05 08:26:55 +00002449- Issue #4533: File read operation was dreadfully slow due to a slowly
2450 growing read buffer. Fixed by using the same growth rate algorithm as
2451 Python 2.x.
2452
Antoine Pitrou5504e892008-12-06 21:27:53 +00002453- Issue #4509: Various issues surrounding resize of bytearray objects to
2454 which there are buffer exports (e.g. memoryview instances).
2455
Georg Brandlf9734072008-12-07 15:30:06 +00002456- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2457 method on file objects with closefd=False. The file descriptor is still
2458 kept open but the file object behaves like a closed file. The ``FileIO``
2459 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00002461- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2467
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002468- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2469 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2470 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2471 of using the replace error handler in PyUnicode_DecodeUTF8().

3029 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
