111 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
112
Antoine Pitroudedbbe62010-07-11 12:15:03 +0000113- Issue #7616: Fix copying of overlapping memoryview slices with the Intel

Ezio Melotti25bc0192010-07-03 05:18:50 +0000116- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

119 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
120 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
121 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

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

600 original socket wasn't retained (instead, a socket with a positive timeout
601 would be turned into a non-blocking SSL socket).
602
Antoine Pitrouec146182010-04-24 21:30:20 +0000603- Issue #5103: SSL handshake would ignore the socket timeout and block
604 indefinitely if the other end didn't respond.

Mark Hammond5a607a32009-05-06 08:04:54 +00001749- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1750 in all operations, including splitdrive, split, etc. splitunc() now issues
1751 a PendingDeprecation warning.
1752
Eric Smith63376222009-05-05 14:04:18 +00001753- Issue #5920: For float.__format__, change the behavior with the
1754 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1755 to be like 'g' but with at least one decimal point and with a
1756 default precision of 12. Previously, the behavior the same but with
1757 a default precision of 6. This more closely matches str(), and
1758 reduces surprises when adding alignment flags to the empty
1759 presentation type. This also affects the new complex.__format__ in
1760 the same way.
1761
Martin v. Löwis011e8422009-05-05 04:43:17 +00001762- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1763
R. David Murrayb18500d2009-05-04 22:59:07 +00001764- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1765 shadowed by classtype's, even if it was None. property now
1766 inserts the __doc__ into the subclass instance __dict__.
1767
Antoine Pitrou244651a2009-05-04 18:56:13 +00001768- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001773- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1774 received a new method, detach(). detach() disconnects the underlying stream
1775 from the buffer or text IO and returns it.
1776
Mark Dickinson33841c32009-05-01 15:37:04 +00001777- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1778 floats with absolute value over 1e50. Also remove length
1779 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1780 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001781
Eric Smith741191f2009-05-06 13:08:15 +00001782- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001783 format(complex(1, 2./3), '.5') now produces a sensible result.
1784
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001785- Issue #5864: Fix empty format code formatting for floats so that it
1786 never gives more than the requested number of significant digits.
1787
Eric Smith6dc46f52009-04-27 20:39:49 +00001788- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1795
Benjamin Peterson193152c2009-04-25 01:08:45 +00001796- Issue #5283: Setting __class__ in __del__ caused a segfault.
1797
Mark Dickinsonad476da2009-04-23 19:14:16 +00001798- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1799 z involves nans, infs or negative zeros.
1800
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001801- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001802
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001803- Issue #1869 (and many duplicates): make round(x, n) correctly
1804 rounded for a float x, by using the decimal <-> binary conversions
1805 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1806 consistently agrees with format(x, '.2f').
1807
Benjamin Petersonae937c02009-04-18 20:54:08 +00001808- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1809 some builtin types.
1810
Eric Smith0923d1d2009-04-16 20:16:10 +00001811- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1812
Eric Smith35e84722009-04-16 20:21:28 +00001813- Issue #5515: str.format() type 'n' combined with commas and leading
1814 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001815
1816- Implement PEP 378, Format Specifier for Thousands Separator, for
1817 floats.
1818
Mark Dickinson3370cce2009-04-17 22:40:53 +00001819- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001820 1e11, not 1e12. This avoids printing 13 significant digits in
1821 situations where only 12 of them are correct. Example problem
1822 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1823 long time.)
1824
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001825- Issue #1580: On most platforms, use a 'short' float repr: for a
1826 finite float x, repr(x) now outputs a string based on the shortest
1827 sequence of decimal digits that rounds to x. Previous behaviour was
1828 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001829 Another minor difference is that the new repr switches to
1830 exponential notation at 1e16 instead of the previous 1e17; this
1831 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001832
1833 There's a new sys attribute sys.float_repr_style, which takes
1834 the value 'short' to indicate that we're using short float repr,
1835 and 'legacy' if the short float repr isn't available for one
1836 reason or another.
1837
1838 The float repr change involves incorporating David Gay's 'perfect
1839 rounding' code into the Python core (it's in Python/dtoa.c). As a
1840 secondary consequence, all string-to-float and float-to-string
1841 conversions (including all float formatting operations) will be
1842 correctly rounded on these platforms.
1843
Georg Brandl442d3b32010-08-01 22:33:12 +00001844 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001845 this change does not apply.
1846
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001847- Issue #5759: float() didn't call __float__ on str subclasses.
1848
Georg Brandlabc38772009-04-12 15:51:51 +00001849- The string.maketrans() function is deprecated; there is a new static method
1850 maketrans() on the bytes and bytearray classes. This removes confusion about
1851 the types string.maketrans() is supposed to work with, and mirrors the
1852 methods available on the str class.
1853
R. David Murraydc6da8a2009-04-09 22:16:43 +00001854- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1859
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001860- Issue #3739: The unicode-internal encoder now reports the number of characters

2077 bytes already but the failure was non-obvious.
2078
Jesse Noller7af4ef82009-03-30 16:47:15 +00002079- Issue #5177: Multiprocessing's SocketListener class now uses

2114 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00002115 struct.error instead of returning b'\xff\xff\xff\xff'. The
2116 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2117 have been removed from the struct module.

2142 rotating the object pointer by 4 bits to the right.
2143
Mark Dickinson87ec0852009-02-09 17:15:59 +00002144- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2145 it now forces its argument to double before testing for infinity.
2146
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002147- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

2155 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002156
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002157- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002158 were suppressing all exceptions. These include list() and bytearray().
2159
Mark Dickinson1124e712009-01-28 21:25:58 +00002160- Issue #4707: round(x, n) now returns an integer if x is an integer.
2161 Previously it returned a float.
2162
Antoine Pitroub52ec782009-01-25 16:34:23 +00002163- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2164 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2165 evaluation loop is compiled with a new dispatch mechanism which gives
2166 speedups of up to 20%, depending on the system, on various benchmarks.
2167
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002168- Issue #4874: Most builtin decoders now reject unicode input.

2174
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002175- Issue #4838: When a module is deallocated, free the memory backing the
2176 optional module state data.
2177
Mark Dickinson8055afd2009-01-17 10:04:45 +00002178- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2179 type to (void *).
2180
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002181- Issue #4935: The overflow checking code in the expandtabs() method common
2182 to str, bytes and bytearray could be optimized away by the compiler, letting
2183 the interpreter segfault instead of raising an error.
2184
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002185- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2186 __next__ method.
2187
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002188- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2189 function no longer attempt to call the __long__ slot to convert an object
2190 to an integer. Only the __int__ and __trunc__ slots are examined.
2191
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002192- Issue #4893: Use NT threading on CE.
2193

2195
Antoine Pitrouab868312009-01-10 15:40:25 +00002196- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2197 common cases are optimized thanks to a dedicated fast path and a moderate
2198 amount of loop unrolling.
2199
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002200- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2201 collecting the oldest generation) so that allocating lots of objects without
2202 destroying them does not show quadratic performance. Based on a proposal by
2203 Martin von Löwis at
2204 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2205
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002206- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002207 having been closed (for instance, a read() call could return some
2208 previously buffered data). Patch by Dmitry Vasiliev.
2209
Antoine Pitrou05608432009-01-09 18:53:14 +00002210- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2211 flag to work properly. Furthermore, when specifying -u, the text stdout
2212 and stderr streams have line-by-line buffering enabled (the default being
2213 to buffer arbitrary chunks of data).
2214
Raymond Hettinger35631532009-01-09 03:58:09 +00002215- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2216 instead of ints (reducing its size from 4 to 8 times thereby reducing
2217 Python's overall memory).
2218
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002219- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2220 an existing .py counterpart, override the co_filename attributes of all
2221 code objects if the original filename is obsolete (which can happen if the
2222 file has been renamed, moved, or if it is accessed through different paths).
2223 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2224
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002225- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2226 one byte. Also fixes the meaning of len() so that it returns the number of
2227 items, rather than the size in bytes.
2228
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002229- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2230
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002231- Issue #4747: When the terminal does not use utf-8, executing a script with
2232 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2233
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002234- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002235 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002236
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002237- Issue #3680: Reference cycles created through a dict, set or deque iterator
2238 did not get collected.
2239
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002240- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2241 where the tp_hash and tp_dict slots are both NULL.
2242
Georg Brandlccc47b62008-12-28 11:44:14 +00002243- Issue #4759: None is now allowed as the first argument of
2244 bytearray.translate(). It was always allowed for bytes.translate().
2245
Skip Montanaro80072cb2008-12-23 03:51:14 +00002246- Added test case to ensure attempts to read from a file opened for writing
2247 fail.
2248
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002249- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00002251- Issue #2183: Simplify and optimize bytecode for list, dict and set
2252 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2253
Antoine Pitrou621601a2008-12-17 23:18:19 +00002254- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2255 print elapsed times, not only when some objects are uncollectable /
2256 unreachable. Original patch by Neil Schemenauer.
2257
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002258- Issue #3439: Add a bit_length method to int.
2259
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002260- Issue #2173: When getting device encoding, check that return value of
2261 nl_langinfo is not the empty string. This was causing silent build
2262 failures on OS X.
2263
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002264- Issue #4597: Fixed several opcodes that weren't always propagating
2265 exceptions.
2266
2267- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002268 context manager returns a value that cannot be converted to a bool.
2269
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002270- Issue #4445: Replace "sizeof(PyBytesObject)" with
2271 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2272 bytes instances. On a typical machine this saves 3 bytes of memory
2273 (on average) per allocation of a bytes instance.
2274
Christian Heimesa872de52008-12-05 08:26:55 +00002275- Issue #4533: File read operation was dreadfully slow due to a slowly
2276 growing read buffer. Fixed by using the same growth rate algorithm as
2277 Python 2.x.
2278
Antoine Pitrou5504e892008-12-06 21:27:53 +00002279- Issue #4509: Various issues surrounding resize of bytearray objects to
2280 which there are buffer exports (e.g. memoryview instances).
2281
Georg Brandlf9734072008-12-07 15:30:06 +00002282- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2283 method on file objects with closefd=False. The file descriptor is still
2284 kept open but the file object behaves like a closed file. The ``FileIO``
2285 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002286
Antoine Pitroubc420402008-12-07 20:14:49 +00002287- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2288 larger than 1.

2293
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002294- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2295 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2296 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2297 of using the replace error handler in PyUnicode_DecodeUTF8().
