22 could crash in many places because of the PyByteArray_AS_STRING() macro
23 returning NULL. The macro now returns a statically allocated empty
24 string instead.
25
Mark Dickinson11f65782010-01-16 18:12:46 +000026- Issue #7632: Fix various str -> float conversion bugs present in 2.7
27 alpha 2, including: (1) a serious 'wrong output' bug that could
28 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
29 that occurred in debug builds when parsing certain long numeric
Mark Dickinsona3ba4a12010-01-17 14:41:03 +000030 strings corresponding to subnormal values, (3) a memory leak for
31 some values large enough to cause overflow, and (4) a number of
32 flaws that could lead to incorrectly rounded results.

48
Mark Dickinsonb6447512009-11-15 10:17:48 +000049- Issue #7298: fixes for range and reversed(range(...)). Iteration
50 over range(a, b, c) incorrectly gave an empty iterator when a, b and
51 c fit in C long but the length of the range did not. Also fix
52 several cases where reversed(range(a, b, c)) gave wrong results, and
53 fix a refleak for reversed(range(a, b, c)) with large arguments.

85 type is specified. Patch by Brian Curtin.
86
Antoine Pitrou66f9fea2010-01-31 23:20:26 +000087- Issue #6939: Fix file I/O objects in the `io` module to keep the original

Georg Brandle6700e92009-08-13 08:39:33 +0000585errors property. Additionally, the errors and encoding properties of StringIO
586are always None now.

Antoine Pitroud9dfaa92009-06-04 20:32:06 +0000588- Issue #6137: The pickle module now translates module names when loading
Georg Brandle6700e92009-08-13 08:39:33 +0000589or dumping pickles with a 2.x-compatible protocol, in order to make data
590sharing and migration easier. This behaviour can be disabled using the
591new `fix_imports` optional argument.

638-----------------
639
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000640- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
641 of the command line.
642

Eric Smith41669ca2009-05-23 14:23:22 +0000645- Issue #6089: Fixed str.format with certain invalid field specifiers
646 that would raise SystemError.
647
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000648- Issue #5982: staticmethod and classmethod now expose the wrapped
649 function with __func__.
650
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000651- Added support for multiple context managers in the same with-statement.
652 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000654- Issue #5829: complex("1e500") no longer raises OverflowError. This
655 makes it consistent with float("1e500") and interpretation of real
656 and imaginary literals.
657
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000658- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

661
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000662- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
663 (1) inf and nan strings with trailing whitespace were incorrectly
664 rejected; (2) parsing of strings representing infinities and nans
665 was locale aware; and (3) the interpretation of fromhex('-nan')
666 didn't match that of float('-nan').

679 arguments for strings with a space in them.
680
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000681- collections.namedtuple() was not working with the following field
682 names: cls, self, tuple, itemgetter, and property.
683
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000684- In unittest, using a skipping decorator on a class is now equivalent to
685 skipping every test on the class. The ClassTestSuite class has been removed.
686
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000687- Issue #6050: Don't fail extracting a directory from a zipfile if
688 the directory already exists.
689
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000690- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
691 than an int, which makes some operations possible under 64-bit Linux (e.g.
692 DN_MULTISHOT with F_NOTIFY).
693

698 by Musashi Tamura, tests by Marcin Bachry.
699
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000700- Issue #1983: Fix functions taking or returning a process identifier to use
701 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
702 a process identifier type wider than the standard C integer type.
703
R. David Murray87e20742009-05-23 01:30:26 +0000704- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

715
Antoine Pitroue4501852009-05-14 18:55:55 +0000716- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
717 library. This means, for example, that opening an UTF-16 text file in
718 append mode doesn't add a BOM at the end of the file if the file isn't
719 empty.
720
R. David Murray74b89242009-05-13 17:33:03 +0000721- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
722 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
723 corrects a pydoc regression.
724
R. David Murray99352742009-05-07 18:24:38 +0000725- Issue 5955: aifc's close method did not close the file it wrapped,
726 now it does. This also means getfp method now returns the real fp.

769Core and Builtins
770-----------------
771
Mark Dickinson865e01a2009-05-07 16:37:01 +0000772- Issue #5914: Add new C API function PyOS_string_to_double, and
773 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
774
Eric Smith741191f2009-05-06 13:08:15 +0000775- Issue #3382: float.__format__, complex.__format__, and %-formatting
776 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
777 affects nan -> NAN and inf -> INF.
778
Mark Hammond5a607a32009-05-06 08:04:54 +0000779- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
780 in all operations, including splitdrive, split, etc. splitunc() now issues
781 a PendingDeprecation warning.
782
Eric Smith63376222009-05-05 14:04:18 +0000783- Issue #5920: For float.__format__, change the behavior with the
784 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
785 to be like 'g' but with at least one decimal point and with a
786 default precision of 12. Previously, the behavior the same but with
787 a default precision of 6. This more closely matches str(), and
788 reduces surprises when adding alignment flags to the empty
789 presentation type. This also affects the new complex.__format__ in
790 the same way.
791
Martin v. Löwis011e8422009-05-05 04:43:17 +0000792- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
793
R. David Murrayb18500d2009-05-04 22:59:07 +0000794- Issue #5890: in subclasses of 'property' the __doc__ attribute was
795 shadowed by classtype's, even if it was None. property now
796 inserts the __doc__ into the subclass instance __dict__.
797
Antoine Pitrou244651a2009-05-04 18:56:13 +0000798- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
799 sequences. Patch by Nick Barnes and Victor Stinner.
800
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000801- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000802
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000803- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
804 received a new method, detach(). detach() disconnects the underlying stream
805 from the buffer or text IO and returns it.
806
Mark Dickinson33841c32009-05-01 15:37:04 +0000807- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
808 floats with absolute value over 1e50. Also remove length
809 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
810 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000811
Eric Smith741191f2009-05-06 13:08:15 +0000812- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000813 format(complex(1, 2./3), '.5') now produces a sensible result.
814
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000815- Issue #5864: Fix empty format code formatting for floats so that it
816 never gives more than the requested number of significant digits.
817
Eric Smith6dc46f52009-04-27 20:39:49 +0000818- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
819 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
820
Eric Smithcc32a112009-04-26 21:35:14 +0000821- Issue #5835: Deprecate PyOS_ascii_formatd.
822
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000823- Issue #4971: Fix titlecase for characters that are their own
824 titlecase, but not their own uppercase.
825
Benjamin Peterson193152c2009-04-25 01:08:45 +0000826- Issue #5283: Setting __class__ in __del__ caused a segfault.
827
Mark Dickinsonad476da2009-04-23 19:14:16 +0000828- Issue #5816: complex(repr(z)) now recovers z exactly, even when
829 z involves nans, infs or negative zeros.
830
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000831- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000832
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000833- Issue #1869 (and many duplicates): make round(x, n) correctly
834 rounded for a float x, by using the decimal <-> binary conversions
835 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
836 consistently agrees with format(x, '.2f').
837
Benjamin Petersonae937c02009-04-18 20:54:08 +0000838- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
839 some builtin types.
840
Eric Smith0923d1d2009-04-16 20:16:10 +0000841- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
842
Eric Smith35e84722009-04-16 20:21:28 +0000843- Issue #5515: str.format() type 'n' combined with commas and leading
844 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000845
846- Implement PEP 378, Format Specifier for Thousands Separator, for
847 floats.
848
Mark Dickinson3370cce2009-04-17 22:40:53 +0000849- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000850 1e11, not 1e12. This avoids printing 13 significant digits in
851 situations where only 12 of them are correct. Example problem
852 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
853 long time.)
854
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000855- Issue #1580: On most platforms, use a 'short' float repr: for a
856 finite float x, repr(x) now outputs a string based on the shortest
857 sequence of decimal digits that rounds to x. Previous behaviour was
858 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000859 Another minor difference is that the new repr switches to
860 exponential notation at 1e16 instead of the previous 1e17; this
861 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000862
863 There's a new sys attribute sys.float_repr_style, which takes
864 the value 'short' to indicate that we're using short float repr,
865 and 'legacy' if the short float repr isn't available for one
866 reason or another.
867
868 The float repr change involves incorporating David Gay's 'perfect
869 rounding' code into the Python core (it's in Python/dtoa.c). As a
870 secondary consequence, all string-to-float and float-to-string
871 conversions (including all float formatting operations) will be
872 correctly rounded on these platforms.
873
874 See issue 1580 discussions for details of platforms for which
875 this change does not apply.
876
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000877- Issue #5759: float() didn't call __float__ on str subclasses.
878
Georg Brandlabc38772009-04-12 15:51:51 +0000879- The string.maketrans() function is deprecated; there is a new static method
880 maketrans() on the bytes and bytearray classes. This removes confusion about
881 the types string.maketrans() is supposed to work with, and mirrors the
882 methods available on the str class.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001187- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001188 were suppressing all exceptions. These include list() and bytearray().
1189
Mark Dickinson1124e712009-01-28 21:25:58 +00001190- Issue #4707: round(x, n) now returns an integer if x is an integer.
1191 Previously it returned a float.
1192
Antoine Pitroub52ec782009-01-25 16:34:23 +00001193- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1194 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1195 evaluation loop is compiled with a new dispatch mechanism which gives
1196 speedups of up to 20%, depending on the system, on various benchmarks.
1197
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001198- Issue #4874: Most builtin decoders now reject unicode input.

1204
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001205- Issue #4838: When a module is deallocated, free the memory backing the
1206 optional module state data.
1207
Mark Dickinson8055afd2009-01-17 10:04:45 +00001208- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1209 type to (void *).
1210
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001211- Issue #4935: The overflow checking code in the expandtabs() method common
1212 to str, bytes and bytearray could be optimized away by the compiler, letting
1213 the interpreter segfault instead of raising an error.
1214
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001215- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1216 __next__ method.
1217
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001218- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1219 function no longer attempt to call the __long__ slot to convert an object
1220 to an integer. Only the __int__ and __trunc__ slots are examined.

1225
Antoine Pitrouab868312009-01-10 15:40:25 +00001226- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1227 common cases are optimized thanks to a dedicated fast path and a moderate
1228 amount of loop unrolling.
1229
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001230- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1231 collecting the oldest generation) so that allocating lots of objects without
1232 destroying them does not show quadratic performance. Based on a proposal by
1233 Martin von Löwis at
1234 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1235
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001236- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001237 having been closed (for instance, a read() call could return some
1238 previously buffered data). Patch by Dmitry Vasiliev.
1239
Antoine Pitrou05608432009-01-09 18:53:14 +00001240- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1241 flag to work properly. Furthermore, when specifying -u, the text stdout
1242 and stderr streams have line-by-line buffering enabled (the default being
1243 to buffer arbitrary chunks of data).
1244
Raymond Hettinger35631532009-01-09 03:58:09 +00001245- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1246 instead of ints (reducing its size from 4 to 8 times thereby reducing
1247 Python's overall memory).
1248
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001249- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1250 an existing .py counterpart, override the co_filename attributes of all
1251 code objects if the original filename is obsolete (which can happen if the
1252 file has been renamed, moved, or if it is accessed through different paths).
1253 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1254
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001255- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1256 one byte. Also fixes the meaning of len() so that it returns the number of
1257 items, rather than the size in bytes.
1258
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001259- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1260
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001261- Issue #4747: When the terminal does not use utf-8, executing a script with
1262 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1263
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001264- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001265 file with `bytes' filename on Windows.

Antoine Pitrou7ddda782009-01-01 15:35:33 +00001267- Issue #3680: Reference cycles created through a dict, set or deque iterator
1268 did not get collected.
1269
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001270- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1271 where the tp_hash and tp_dict slots are both NULL.
1272
Georg Brandlccc47b62008-12-28 11:44:14 +00001273- Issue #4759: None is now allowed as the first argument of
1274 bytearray.translate(). It was always allowed for bytes.translate().
1275
Skip Montanaro80072cb2008-12-23 03:51:14 +00001276- Added test case to ensure attempts to read from a file opened for writing
1277 fail.
1278
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001279- Issue #3106: Speedup some comparisons (str/str and int/int).

1283
Antoine Pitrou621601a2008-12-17 23:18:19 +00001284- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1286 unreachable. Original patch by Neil Schemenauer.
1287
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001288- Issue #3439: Add a bit_length method to int.
1289
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001290- Issue #2173: When getting device encoding, check that return value of
1291 nl_langinfo is not the empty string. This was causing silent build
1292 failures on OS X.
1293
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001294- Issue #4597: Fixed several opcodes that weren't always propagating
1295 exceptions.
1296
1297- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001298 context manager returns a value that cannot be converted to a bool.
1299
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001300- Issue #4445: Replace "sizeof(PyBytesObject)" with
1301 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1302 bytes instances. On a typical machine this saves 3 bytes of memory
1303 (on average) per allocation of a bytes instance.
1304
Christian Heimesa872de52008-12-05 08:26:55 +00001305- Issue #4533: File read operation was dreadfully slow due to a slowly
1306 growing read buffer. Fixed by using the same growth rate algorithm as
1307 Python 2.x.
1308
Antoine Pitrou5504e892008-12-06 21:27:53 +00001309- Issue #4509: Various issues surrounding resize of bytearray objects to
1310 which there are buffer exports (e.g. memoryview instances).
1311
Georg Brandlf9734072008-12-07 15:30:06 +00001312- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1313 method on file objects with closefd=False. The file descriptor is still
1314 kept open but the file object behaves like a closed file. The ``FileIO``
1315 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00001317- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1323
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001324- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1325 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1326 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1327 of using the replace error handler in PyUnicode_DecodeUTF8().
