151 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
152

160 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

641 would be turned into a non-blocking SSL socket).
642
Antoine Pitrouec146182010-04-24 21:30:20 +0000643- Issue #5103: SSL handshake would ignore the socket timeout and block

647 the SSL structure if necessary (as other methods already do).

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

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001777*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001778
1779Core and Builtins
1780-----------------
1781
Mark Dickinson865e01a2009-05-07 16:37:01 +00001782- Issue #5914: Add new C API function PyOS_string_to_double, and
1783 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1784
Eric Smith741191f2009-05-06 13:08:15 +00001785- Issue #3382: float.__format__, complex.__format__, and %-formatting
1786 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1787 affects nan -> NAN and inf -> INF.
1788
Mark Hammond5a607a32009-05-06 08:04:54 +00001789- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1790 in all operations, including splitdrive, split, etc. splitunc() now issues
1791 a PendingDeprecation warning.
1792
Eric Smith63376222009-05-05 14:04:18 +00001793- Issue #5920: For float.__format__, change the behavior with the
1794 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1795 to be like 'g' but with at least one decimal point and with a
1796 default precision of 12. Previously, the behavior the same but with
1797 a default precision of 6. This more closely matches str(), and
1798 reduces surprises when adding alignment flags to the empty
1799 presentation type. This also affects the new complex.__format__ in
1800 the same way.
1801
Martin v. Löwis011e8422009-05-05 04:43:17 +00001802- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1803
R. David Murrayb18500d2009-05-04 22:59:07 +00001804- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1805 shadowed by classtype's, even if it was None. property now
1806 inserts the __doc__ into the subclass instance __dict__.
1807
Antoine Pitrou244651a2009-05-04 18:56:13 +00001808- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1809 sequences. Patch by Nick Barnes and Victor Stinner.
1810
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001811- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001812
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001813- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1814 received a new method, detach(). detach() disconnects the underlying stream
1815 from the buffer or text IO and returns it.
1816
Mark Dickinson33841c32009-05-01 15:37:04 +00001817- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1818 floats with absolute value over 1e50. Also remove length
1819 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1820 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001821
Eric Smith741191f2009-05-06 13:08:15 +00001822- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001823 format(complex(1, 2./3), '.5') now produces a sensible result.
1824
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001825- Issue #5864: Fix empty format code formatting for floats so that it
1826 never gives more than the requested number of significant digits.
1827
Eric Smith6dc46f52009-04-27 20:39:49 +00001828- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1829 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1830
Eric Smithcc32a112009-04-26 21:35:14 +00001831- Issue #5835: Deprecate PyOS_ascii_formatd.
1832
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001833- Issue #4971: Fix titlecase for characters that are their own
1834 titlecase, but not their own uppercase.
1835
Benjamin Peterson193152c2009-04-25 01:08:45 +00001836- Issue #5283: Setting __class__ in __del__ caused a segfault.
1837
Mark Dickinsonad476da2009-04-23 19:14:16 +00001838- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1839 z involves nans, infs or negative zeros.
1840
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001841- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001842
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001843- Issue #1869 (and many duplicates): make round(x, n) correctly
1844 rounded for a float x, by using the decimal <-> binary conversions
1845 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1846 consistently agrees with format(x, '.2f').
1847
Benjamin Petersonae937c02009-04-18 20:54:08 +00001848- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1849 some builtin types.
1850
Eric Smith0923d1d2009-04-16 20:16:10 +00001851- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1852
Eric Smith35e84722009-04-16 20:21:28 +00001853- Issue #5515: str.format() type 'n' combined with commas and leading
1854 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001855
1856- Implement PEP 378, Format Specifier for Thousands Separator, for
1857 floats.
1858
Mark Dickinson3370cce2009-04-17 22:40:53 +00001859- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001860 1e11, not 1e12. This avoids printing 13 significant digits in
1861 situations where only 12 of them are correct. Example problem
1862 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1863 long time.)
1864
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001865- Issue #1580: On most platforms, use a 'short' float repr: for a
1866 finite float x, repr(x) now outputs a string based on the shortest
1867 sequence of decimal digits that rounds to x. Previous behaviour was
1868 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001869 Another minor difference is that the new repr switches to
1870 exponential notation at 1e16 instead of the previous 1e17; this
1871 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001872
1873 There's a new sys attribute sys.float_repr_style, which takes
1874 the value 'short' to indicate that we're using short float repr,
1875 and 'legacy' if the short float repr isn't available for one
1876 reason or another.
1877
1878 The float repr change involves incorporating David Gay's 'perfect
1879 rounding' code into the Python core (it's in Python/dtoa.c). As a
1880 secondary consequence, all string-to-float and float-to-string
1881 conversions (including all float formatting operations) will be
1882 correctly rounded on these platforms.
1883
Georg Brandl442d3b32010-08-01 22:33:12 +00001884 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001885 this change does not apply.
1886
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001887- Issue #5759: float() didn't call __float__ on str subclasses.
1888
Georg Brandlabc38772009-04-12 15:51:51 +00001889- The string.maketrans() function is deprecated; there is a new static method
1890 maketrans() on the bytes and bytearray classes. This removes confusion about
1891 the types string.maketrans() is supposed to work with, and mirrors the
1892 methods available on the str class.
1893
R. David Murraydc6da8a2009-04-09 22:16:43 +00001894- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1895 its clarity and its speed.
1896
Matthias Klose091c7b12009-04-07 13:24:27 +00001897- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1898 to avoid compiler warnings.
1899
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001900- Issue #3739: The unicode-internal encoder now reports the number of characters
1901 consumed like any other encoder (instead of the number of bytes).

Georg Brandl406b3d82009-04-11 21:24:37 +00002041- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
2042 when hitting the recursion limit under certain circumstances.
2043
Brett Cannon0759dd62009-04-01 18:13:07 +00002044- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
2045
Georg Brandlab6f2f62009-03-31 04:16:10 +00002046- Fix a segfault when running test_exceptions with coverage, caused by
2047 insufficient checks in accessors of Exception.__context__.
2048
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002049- Issue #5604: non-ASCII characters in module name passed to
2050 imp.find_module() were converted to UTF-8 while the path is
2051 converted to the default filesystem encoding, causing nonsense.
2052
Benjamin Peterson09832742009-03-26 17:15:46 +00002053- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002055- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2056 the end sys.path, for compatibility with the system install of Python.
2057
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002058- Issue #4688: Add a heuristic so that tuples and dicts containing only
2059 untrackable objects are not tracked by the garbage collector. This can
2060 reduce the size of collections and therefore the garbage collection overhead
2061 on long-running programs, depending on their particular use of datatypes.
2062
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002063- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
2064 improve its performance. Long divisions and remainder operations
2065 are now between 50% and 150% faster.
2066
Mark Dickinsonbd792642009-03-18 20:06:12 +00002067- Issue #4258: Make it possible to use base 2**30 instead of base
2068 2**15 for the internal representation of integers, for performance
2069 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2070 --enable-big-digits option to configure, which overrides the
2071 default. Add sys.int_info structseq to provide information about
2072 the internal format.
2073
Mark Dickinson081dfee2009-03-18 14:47:41 +00002074- Issue #4474: PyUnicode_FromWideChar now converts characters outside
2075 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2076 and sizeof(Py_UNICODE) == 2.
2077
Eric Smith8ec90442009-03-14 12:29:34 +00002078- Issue #5237: Allow auto-numbered fields in str.format(). For
2079 example: '{} {}'.format(1, 2) == '1 2'.
2080
Antoine Pitrou652e7072009-03-13 19:25:20 +00002081- Issue #5392: when a very low recursion limit was set, the interpreter would
2082 abort with a fatal error after the recursion limit was hit twice.
2083
Matthias Klose042f1332009-04-04 14:32:42 +00002084- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2130
Lars Gustäbel42e00912009-03-22 20:34:29 +00002131- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2132 forever on incomplete input. That caused tarfile.open() to hang when used
2133 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2134 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00002155 struct.error instead of returning b'\xff\xff\xff\xff'. The
2156 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

2182 rotating the object pointer by 4 bits to the right.
2183
Mark Dickinson87ec0852009-02-09 17:15:59 +00002184- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2185 it now forces its argument to double before testing for infinity.
2186
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002187- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2188 returns a non-number type.
2189
Benjamin Peterson87618552009-02-08 15:00:52 +00002190- Issue #5182: Removed memoryview.__str__.

2195 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002196
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002197- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002198 were suppressing all exceptions. These include list() and bytearray().
2199
Mark Dickinson1124e712009-01-28 21:25:58 +00002200- Issue #4707: round(x, n) now returns an integer if x is an integer.
2201 Previously it returned a float.
2202
Antoine Pitroub52ec782009-01-25 16:34:23 +00002203- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2204 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2205 evaluation loop is compiled with a new dispatch mechanism which gives
2206 speedups of up to 20%, depending on the system, on various benchmarks.
2207
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002208- Issue #4874: Most builtin decoders now reject unicode input.

2214
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002215- Issue #4838: When a module is deallocated, free the memory backing the
2216 optional module state data.
2217
Mark Dickinson8055afd2009-01-17 10:04:45 +00002218- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2219 type to (void *).
2220
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002221- Issue #4935: The overflow checking code in the expandtabs() method common
2222 to str, bytes and bytearray could be optimized away by the compiler, letting
2223 the interpreter segfault instead of raising an error.
2224
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002225- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2226 __next__ method.
2227
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002228- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

2235
Antoine Pitrouab868312009-01-10 15:40:25 +00002236- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2237 common cases are optimized thanks to a dedicated fast path and a moderate
2238 amount of loop unrolling.
2239
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002240- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2241 collecting the oldest generation) so that allocating lots of objects without
2242 destroying them does not show quadratic performance. Based on a proposal by
2243 Martin von Löwis at
2244 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2245
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002246- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002247 having been closed (for instance, a read() call could return some
2248 previously buffered data). Patch by Dmitry Vasiliev.
2249
Antoine Pitrou05608432009-01-09 18:53:14 +00002250- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2251 flag to work properly. Furthermore, when specifying -u, the text stdout
2252 and stderr streams have line-by-line buffering enabled (the default being
2253 to buffer arbitrary chunks of data).
2254
Raymond Hettinger35631532009-01-09 03:58:09 +00002255- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2256 instead of ints (reducing its size from 4 to 8 times thereby reducing
2257 Python's overall memory).
2258
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002259- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2260 an existing .py counterpart, override the co_filename attributes of all
2261 code objects if the original filename is obsolete (which can happen if the
2262 file has been renamed, moved, or if it is accessed through different paths).
2263 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2264
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002265- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2266 one byte. Also fixes the meaning of len() so that it returns the number of
2267 items, rather than the size in bytes.
2268
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002269- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2270
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002271- Issue #4747: When the terminal does not use utf-8, executing a script with
2272 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2273
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002274- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002275 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002276
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002277- Issue #3680: Reference cycles created through a dict, set or deque iterator
2278 did not get collected.
2279
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002280- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2281 where the tp_hash and tp_dict slots are both NULL.
2282
Georg Brandlccc47b62008-12-28 11:44:14 +00002283- Issue #4759: None is now allowed as the first argument of
2284 bytearray.translate(). It was always allowed for bytes.translate().
2285
Skip Montanaro80072cb2008-12-23 03:51:14 +00002286- Added test case to ensure attempts to read from a file opened for writing
2287 fail.
2288
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002289- Issue #3106: Speedup some comparisons (str/str and int/int).

2292 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2293
Antoine Pitrou621601a2008-12-17 23:18:19 +00002294- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2295 print elapsed times, not only when some objects are uncollectable /
2296 unreachable. Original patch by Neil Schemenauer.
2297
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002298- Issue #3439: Add a bit_length method to int.
2299
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002300- Issue #2173: When getting device encoding, check that return value of
2301 nl_langinfo is not the empty string. This was causing silent build
2302 failures on OS X.
2303
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002304- Issue #4597: Fixed several opcodes that weren't always propagating
2305 exceptions.
2306
2307- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002308 context manager returns a value that cannot be converted to a bool.
2309
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002310- Issue #4445: Replace "sizeof(PyBytesObject)" with
2311 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2312 bytes instances. On a typical machine this saves 3 bytes of memory
2313 (on average) per allocation of a bytes instance.
2314
Christian Heimesa872de52008-12-05 08:26:55 +00002315- Issue #4533: File read operation was dreadfully slow due to a slowly
2316 growing read buffer. Fixed by using the same growth rate algorithm as
2317 Python 2.x.
2318
Antoine Pitrou5504e892008-12-06 21:27:53 +00002319- Issue #4509: Various issues surrounding resize of bytearray objects to
2320 which there are buffer exports (e.g. memoryview instances).
2321
Georg Brandlf9734072008-12-07 15:30:06 +00002322- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
