728 being followed, leading to the wrong Python exception being raised.

759 witnessed in test_httpservers.
760
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000761- Issue #8524: When creating an SSL socket, the timeout value of the
762 original socket wasn't retained (instead, a socket with a positive timeout
763 would be turned into a non-blocking SSL socket).
764
Antoine Pitrouec146182010-04-24 21:30:20 +0000765- Issue #5103: SSL handshake would ignore the socket timeout and block
766 indefinitely if the other end didn't respond.
767
768- The do_handshake() method of SSL objects now adjusts the blocking mode of
769 the SSL structure if necessary (as other methods already do).

1778 that would raise SystemError.
1779
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001780- Issue #5982: staticmethod and classmethod now expose the wrapped
1781 function with __func__.
1782
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001783- Added support for multiple context managers in the same with-statement.
1784 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001786- Issue #5829: complex("1e500") no longer raises OverflowError. This
1787 makes it consistent with float("1e500") and interpretation of real
1788 and imaginary literals.
1789
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001790- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

1795 (1) inf and nan strings with trailing whitespace were incorrectly
1796 rejected; (2) parsing of strings representing infinities and nans
1797 was locale aware; and (3) the interpretation of fromhex('-nan')
1798 didn't match that of float('-nan').

1815
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001816- In unittest, using a skipping decorator on a class is now equivalent to
1817 skipping every test on the class. The ClassTestSuite class has been removed.
1818
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001819- Issue #6050: Don't fail extracting a directory from a zipfile if
1820 the directory already exists.
1821
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001822- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1823 than an int, which makes some operations possible under 64-bit Linux (e.g.
1824 DN_MULTISHOT with F_NOTIFY).
1825
Antoine Pitrou716c4442009-05-23 19:04:03 +00001826- Issue #5761: Add the name of the underlying file to the repr() of various

1828
R. David Murraycaa27b72009-05-23 18:49:56 +00001829- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1830 by Musashi Tamura, tests by Marcin Bachry.
1831
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001832- Issue #1983: Fix functions taking or returning a process identifier to use
1833 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1834 a process identifier type wider than the standard C integer type.
1835

1847
Antoine Pitroue4501852009-05-14 18:55:55 +00001848- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1849 library. This means, for example, that opening an UTF-16 text file in
1850 append mode doesn't add a BOM at the end of the file if the file isn't
1851 empty.
1852
R. David Murray74b89242009-05-13 17:33:03 +00001853- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

1855 corrects a pydoc regression.
1856
Georg Brandl442d3b32010-08-01 22:33:12 +00001857- Issue #5955: aifc's close method did not close the file it wrapped,

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001899*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001900
1901Core and Builtins
1902-----------------
1903
Mark Dickinson865e01a2009-05-07 16:37:01 +00001904- Issue #5914: Add new C API function PyOS_string_to_double, and
1905 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1906
Eric Smith741191f2009-05-06 13:08:15 +00001907- Issue #3382: float.__format__, complex.__format__, and %-formatting
1908 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1909 affects nan -> NAN and inf -> INF.
1910
Mark Hammond5a607a32009-05-06 08:04:54 +00001911- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1912 in all operations, including splitdrive, split, etc. splitunc() now issues
1913 a PendingDeprecation warning.
1914
Eric Smith63376222009-05-05 14:04:18 +00001915- Issue #5920: For float.__format__, change the behavior with the
1916 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1917 to be like 'g' but with at least one decimal point and with a
1918 default precision of 12. Previously, the behavior the same but with
1919 a default precision of 6. This more closely matches str(), and
1920 reduces surprises when adding alignment flags to the empty
1921 presentation type. This also affects the new complex.__format__ in
1922 the same way.
1923
Martin v. Löwis011e8422009-05-05 04:43:17 +00001924- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1925
R. David Murrayb18500d2009-05-04 22:59:07 +00001926- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1927 shadowed by classtype's, even if it was None. property now
1928 inserts the __doc__ into the subclass instance __dict__.
1929
Antoine Pitrou244651a2009-05-04 18:56:13 +00001930- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1931 sequences. Patch by Nick Barnes and Victor Stinner.
1932
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001933- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001934
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001935- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1936 received a new method, detach(). detach() disconnects the underlying stream
1937 from the buffer or text IO and returns it.
1938
Mark Dickinson33841c32009-05-01 15:37:04 +00001939- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1940 floats with absolute value over 1e50. Also remove length
1941 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1942 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001943
Eric Smith741191f2009-05-06 13:08:15 +00001944- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001945 format(complex(1, 2./3), '.5') now produces a sensible result.
1946
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001947- Issue #5864: Fix empty format code formatting for floats so that it
1948 never gives more than the requested number of significant digits.
1949
Eric Smith6dc46f52009-04-27 20:39:49 +00001950- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1951 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1952
Eric Smithcc32a112009-04-26 21:35:14 +00001953- Issue #5835: Deprecate PyOS_ascii_formatd.
1954
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001955- Issue #4971: Fix titlecase for characters that are their own
1956 titlecase, but not their own uppercase.
1957
Benjamin Peterson193152c2009-04-25 01:08:45 +00001958- Issue #5283: Setting __class__ in __del__ caused a segfault.
1959
Mark Dickinsonad476da2009-04-23 19:14:16 +00001960- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1961 z involves nans, infs or negative zeros.
1962
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001963- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001964
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001965- Issue #1869 (and many duplicates): make round(x, n) correctly
1966 rounded for a float x, by using the decimal <-> binary conversions
1967 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1968 consistently agrees with format(x, '.2f').
1969
Benjamin Petersonae937c02009-04-18 20:54:08 +00001970- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1971 some builtin types.
1972
Eric Smith0923d1d2009-04-16 20:16:10 +00001973- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1974
Eric Smith35e84722009-04-16 20:21:28 +00001975- Issue #5515: str.format() type 'n' combined with commas and leading
1976 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001977
1978- Implement PEP 378, Format Specifier for Thousands Separator, for
1979 floats.
1980
Mark Dickinson3370cce2009-04-17 22:40:53 +00001981- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001982 1e11, not 1e12. This avoids printing 13 significant digits in
1983 situations where only 12 of them are correct. Example problem
1984 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1985 long time.)
1986
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001987- Issue #1580: On most platforms, use a 'short' float repr: for a
1988 finite float x, repr(x) now outputs a string based on the shortest
1989 sequence of decimal digits that rounds to x. Previous behaviour was
1990 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001991 Another minor difference is that the new repr switches to
1992 exponential notation at 1e16 instead of the previous 1e17; this
1993 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001994
1995 There's a new sys attribute sys.float_repr_style, which takes
1996 the value 'short' to indicate that we're using short float repr,
1997 and 'legacy' if the short float repr isn't available for one
1998 reason or another.
1999
2000 The float repr change involves incorporating David Gay's 'perfect
2001 rounding' code into the Python core (it's in Python/dtoa.c). As a
2002 secondary consequence, all string-to-float and float-to-string
2003 conversions (including all float formatting operations) will be
2004 correctly rounded on these platforms.
2005
Georg Brandl442d3b32010-08-01 22:33:12 +00002006 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002007 this change does not apply.
2008
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002009- Issue #5759: float() didn't call __float__ on str subclasses.
2010
Georg Brandlabc38772009-04-12 15:51:51 +00002011- The string.maketrans() function is deprecated; there is a new static method
2012 maketrans() on the bytes and bytearray classes. This removes confusion about
2013 the types string.maketrans() is supposed to work with, and mirrors the
2014 methods available on the str class.
2015
R. David Murraydc6da8a2009-04-09 22:16:43 +00002016- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2017 its clarity and its speed.
2018
Matthias Klose091c7b12009-04-07 13:24:27 +00002019- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2020 to avoid compiler warnings.
2021
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002022- Issue #3739: The unicode-internal encoder now reports the number of characters
2023 consumed like any other encoder (instead of the number of bytes).

Antoine Pitroub52ec782009-01-25 16:34:23 +00002325- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2326 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2327 evaluation loop is compiled with a new dispatch mechanism which gives
2328 speedups of up to 20%, depending on the system, on various benchmarks.
2329
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002330- Issue #4874: Most builtin decoders now reject unicode input.

2336
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002337- Issue #4838: When a module is deallocated, free the memory backing the
2338 optional module state data.
2339
Mark Dickinson8055afd2009-01-17 10:04:45 +00002340- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2341 type to (void *).
2342
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002343- Issue #4935: The overflow checking code in the expandtabs() method common
2344 to str, bytes and bytearray could be optimized away by the compiler, letting
2345 the interpreter segfault instead of raising an error.
2346
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002347- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2348 __next__ method.
2349
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002350- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2351 function no longer attempt to call the __long__ slot to convert an object
2352 to an integer. Only the __int__ and __trunc__ slots are examined.
2353
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002354- Issue #4893: Use NT threading on CE.

2357
Antoine Pitrouab868312009-01-10 15:40:25 +00002358- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2359 common cases are optimized thanks to a dedicated fast path and a moderate
2360 amount of loop unrolling.
2361
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002362- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2363 collecting the oldest generation) so that allocating lots of objects without
2364 destroying them does not show quadratic performance. Based on a proposal by
2365 Martin von Löwis at
2366 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2367
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002368- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002369 having been closed (for instance, a read() call could return some
2370 previously buffered data). Patch by Dmitry Vasiliev.
2371
Antoine Pitrou05608432009-01-09 18:53:14 +00002372- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2373 flag to work properly. Furthermore, when specifying -u, the text stdout
2374 and stderr streams have line-by-line buffering enabled (the default being
2375 to buffer arbitrary chunks of data).
2376
Raymond Hettinger35631532009-01-09 03:58:09 +00002377- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2378 instead of ints (reducing its size from 4 to 8 times thereby reducing
2379 Python's overall memory).
2380
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002381- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2382 an existing .py counterpart, override the co_filename attributes of all
2383 code objects if the original filename is obsolete (which can happen if the
2384 file has been renamed, moved, or if it is accessed through different paths).
2385 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2386
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002387- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2388 one byte. Also fixes the meaning of len() so that it returns the number of
2389 items, rather than the size in bytes.
2390
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002391- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2392
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002393- Issue #4747: When the terminal does not use utf-8, executing a script with
2394 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2395
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002396- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002397 file with `bytes' filename on Windows.

2400 did not get collected.
2401
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002402- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2403 where the tp_hash and tp_dict slots are both NULL.
2404
Georg Brandlccc47b62008-12-28 11:44:14 +00002405- Issue #4759: None is now allowed as the first argument of
2406 bytearray.translate(). It was always allowed for bytes.translate().
2407
Skip Montanaro80072cb2008-12-23 03:51:14 +00002408- Added test case to ensure attempts to read from a file opened for writing
2409 fail.

2415
Antoine Pitrou621601a2008-12-17 23:18:19 +00002416- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

2421
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002422- Issue #2173: When getting device encoding, check that return value of
2423 nl_langinfo is not the empty string. This was causing silent build
2424 failures on OS X.
2425
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002426- Issue #4597: Fixed several opcodes that weren't always propagating
2427 exceptions.
2428
2429- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002430 context manager returns a value that cannot be converted to a bool.
2431
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002432- Issue #4445: Replace "sizeof(PyBytesObject)" with
2433 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2434 bytes instances. On a typical machine this saves 3 bytes of memory
2435 (on average) per allocation of a bytes instance.
2436
Christian Heimesa872de52008-12-05 08:26:55 +00002437- Issue #4533: File read operation was dreadfully slow due to a slowly
2438 growing read buffer. Fixed by using the same growth rate algorithm as
2439 Python 2.x.
2440
Antoine Pitrou5504e892008-12-06 21:27:53 +00002441- Issue #4509: Various issues surrounding resize of bytearray objects to
2442 which there are buffer exports (e.g. memoryview instances).
2443
Georg Brandlf9734072008-12-07 15:30:06 +00002444- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2445 method on file objects with closefd=False. The file descriptor is still
2446 kept open but the file object behaves like a closed file. The ``FileIO``
2447 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002448
Antoine Pitroubc420402008-12-07 20:14:49 +00002449- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2455
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002456- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2457 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2458 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2459 of using the replace error handler in PyUnicode_DecodeUTF8().

2738 do an explicit seek to the end of file (so that e.g. tell() returns the
