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.

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

697 rejected; (2) parsing of strings representing infinities and nans
698 was locale aware; and (3) the interpretation of fromhex('-nan')
699 didn't match that of float('-nan').

750 library. This means, for example, that opening an UTF-16 text file in
751 append mode doesn't add a BOM at the end of the file if the file isn't
752 empty.

802Core and Builtins

804
Mark Dickinson865e01a2009-05-07 16:37:01 +0000805- Issue #5914: Add new C API function PyOS_string_to_double, and
806 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
807
Eric Smith741191f2009-05-06 13:08:15 +0000808- Issue #3382: float.__format__, complex.__format__, and %-formatting
809 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
810 affects nan -> NAN and inf -> INF.
811
Mark Hammond5a607a32009-05-06 08:04:54 +0000812- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
813 in all operations, including splitdrive, split, etc. splitunc() now issues
814 a PendingDeprecation warning.
815
Eric Smith63376222009-05-05 14:04:18 +0000816- Issue #5920: For float.__format__, change the behavior with the
817 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
818 to be like 'g' but with at least one decimal point and with a
819 default precision of 12. Previously, the behavior the same but with
820 a default precision of 6. This more closely matches str(), and
821 reduces surprises when adding alignment flags to the empty
822 presentation type. This also affects the new complex.__format__ in
823 the same way.
824
Martin v. Löwis011e8422009-05-05 04:43:17 +0000825- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

R. David Murrayb18500d2009-05-04 22:59:07 +0000827- Issue #5890: in subclasses of 'property' the __doc__ attribute was
828 shadowed by classtype's, even if it was None. property now
829 inserts the __doc__ into the subclass instance __dict__.
830
Antoine Pitrou244651a2009-05-04 18:56:13 +0000831- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
832 sequences. Patch by Nick Barnes and Victor Stinner.
833
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000834- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000835
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000836- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
837 received a new method, detach(). detach() disconnects the underlying stream
838 from the buffer or text IO and returns it.
839
Mark Dickinson33841c32009-05-01 15:37:04 +0000840- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
841 floats with absolute value over 1e50. Also remove length
842 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
843 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000844
Eric Smith741191f2009-05-06 13:08:15 +0000845- Issue #1588: Add complex.__format__. For example,

849 never gives more than the requested number of significant digits.
850
Eric Smith6dc46f52009-04-27 20:39:49 +0000851- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
852 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
853
Eric Smithcc32a112009-04-26 21:35:14 +0000854- Issue #5835: Deprecate PyOS_ascii_formatd.
855

860
Mark Dickinsonad476da2009-04-23 19:14:16 +0000861- Issue #5816: complex(repr(z)) now recovers z exactly, even when
862 z involves nans, infs or negative zeros.
863
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000864- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000865
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000866- Issue #1869 (and many duplicates): make round(x, n) correctly
867 rounded for a float x, by using the decimal <-> binary conversions
868 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
869 consistently agrees with format(x, '.2f').
870
Benjamin Petersonae937c02009-04-18 20:54:08 +0000871- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

873
Eric Smith0923d1d2009-04-16 20:16:10 +0000874- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
875
Eric Smith35e84722009-04-16 20:21:28 +0000876- Issue #5515: str.format() type 'n' combined with commas and leading
877 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000878
879- Implement PEP 378, Format Specifier for Thousands Separator, for
880 floats.
881
Mark Dickinson3370cce2009-04-17 22:40:53 +0000882- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000883 1e11, not 1e12. This avoids printing 13 significant digits in
884 situations where only 12 of them are correct. Example problem
885 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
886 long time.)
887
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000888- Issue #1580: On most platforms, use a 'short' float repr: for a
889 finite float x, repr(x) now outputs a string based on the shortest
890 sequence of decimal digits that rounds to x. Previous behaviour was
891 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000892 Another minor difference is that the new repr switches to
893 exponential notation at 1e16 instead of the previous 1e17; this
894 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000895
896 There's a new sys attribute sys.float_repr_style, which takes
897 the value 'short' to indicate that we're using short float repr,
898 and 'legacy' if the short float repr isn't available for one
899 reason or another.
900
901 The float repr change involves incorporating David Gay's 'perfect
902 rounding' code into the Python core (it's in Python/dtoa.c). As a
903 secondary consequence, all string-to-float and float-to-string
904 conversions (including all float formatting operations) will be
905 correctly rounded on these platforms.
906
907 See issue 1580 discussions for details of platforms for which
908 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000910- Issue #5759: float() didn't call __float__ on str subclasses.
911
Georg Brandlabc38772009-04-12 15:51:51 +0000912- The string.maketrans() function is deprecated; there is a new static method
913 maketrans() on the bytes and bytearray classes. This removes confusion about
914 the types string.maketrans() is supposed to work with, and mirrors the
915 methods available on the str class.

1196 used when using str.format() with str, int, and float arguments.
1197
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00001198- Issue #5249: time.strftime returned malformed string when format string
1199 contained non ascii character on windows.
1200
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001201- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1202 source has already been decoded into str.
1203
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001204- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1205 rotating the object pointer by 4 bits to the right.
1206
Mark Dickinson87ec0852009-02-09 17:15:59 +00001207- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1208 it now forces its argument to double before testing for infinity.
1209
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001210- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsone94c6792009-02-02 20:36:42 +00001217 the type definition cmpfunc. The tp_compare slot has been renamed
1218 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001219
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001220- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001221 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00001223- Issue #4707: round(x, n) now returns an integer if x is an integer.
1224 Previously it returned a float.
1225
Antoine Pitroub52ec782009-01-25 16:34:23 +00001226- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1227 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1228 evaluation loop is compiled with a new dispatch mechanism which gives
1229 speedups of up to 20%, depending on the system, on various benchmarks.
1230
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001231- Issue #4874: Most builtin decoders now reject unicode input.

1235
Benjamin Peterson05e782f2009-01-19 15:15:02 +00001236- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
1237
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001238- Issue #4838: When a module is deallocated, free the memory backing the
1239 optional module state data.
1240
Mark Dickinson8055afd2009-01-17 10:04:45 +00001241- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1242 type to (void *).
1243
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001244- Issue #4935: The overflow checking code in the expandtabs() method common
1245 to str, bytes and bytearray could be optimized away by the compiler, letting
1246 the interpreter segfault instead of raising an error.
1247
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001248- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1249 __next__ method.
1250
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001251- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1252 function no longer attempt to call the __long__ slot to convert an object
1253 to an integer. Only the __int__ and __trunc__ slots are examined.
1254
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001255- Issue #4893: Use NT threading on CE.
1256
Martin v. Löwisec59d042009-01-12 07:59:10 +00001257- Issue #4915: Port sysmodule to Windows CE.
1258
Antoine Pitrouab868312009-01-10 15:40:25 +00001259- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1260 common cases are optimized thanks to a dedicated fast path and a moderate
1261 amount of loop unrolling.
1262
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001263- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1264 collecting the oldest generation) so that allocating lots of objects without
1265 destroying them does not show quadratic performance. Based on a proposal by
1266 Martin von Löwis at
1267 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1268
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001269- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001270 having been closed (for instance, a read() call could return some
1271 previously buffered data). Patch by Dmitry Vasiliev.
1272
Antoine Pitrou05608432009-01-09 18:53:14 +00001273- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1274 flag to work properly. Furthermore, when specifying -u, the text stdout
1275 and stderr streams have line-by-line buffering enabled (the default being
1276 to buffer arbitrary chunks of data).
1277
Raymond Hettinger35631532009-01-09 03:58:09 +00001278- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1279 instead of ints (reducing its size from 4 to 8 times thereby reducing
1280 Python's overall memory).
1281
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001282- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1283 an existing .py counterpart, override the co_filename attributes of all
1284 code objects if the original filename is obsolete (which can happen if the
1285 file has been renamed, moved, or if it is accessed through different paths).
1286 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1287
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001288- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1289 one byte. Also fixes the meaning of len() so that it returns the number of
1290 items, rather than the size in bytes.
1291
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001292- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1293
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001294- Issue #4747: When the terminal does not use utf-8, executing a script with
1295 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1296
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001297- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001298 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001299
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001300- Issue #3680: Reference cycles created through a dict, set or deque iterator
1301 did not get collected.
1302
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001303- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1304 where the tp_hash and tp_dict slots are both NULL.
1305
Georg Brandlccc47b62008-12-28 11:44:14 +00001306- Issue #4759: None is now allowed as the first argument of
1307 bytearray.translate(). It was always allowed for bytes.translate().
1308
Skip Montanaro80072cb2008-12-23 03:51:14 +00001309- Added test case to ensure attempts to read from a file opened for writing
1310 fail.
1311
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001312- Issue #3106: Speedup some comparisons (str/str and int/int).
1313
Antoine Pitrouf289ae62008-12-18 11:06:25 +00001314- Issue #2183: Simplify and optimize bytecode for list, dict and set
1315 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1316
Antoine Pitrou621601a2008-12-17 23:18:19 +00001317- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1318 print elapsed times, not only when some objects are uncollectable /
1319 unreachable. Original patch by Neil Schemenauer.
1320
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001321- Issue #3439: Add a bit_length method to int.
1322
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001323- Issue #2173: When getting device encoding, check that return value of
1324 nl_langinfo is not the empty string. This was causing silent build
1325 failures on OS X.
1326
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001327- Issue #4597: Fixed several opcodes that weren't always propagating
1328 exceptions.
1329
1330- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001331 context manager returns a value that cannot be converted to a bool.
1332
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001333- Issue #4445: Replace "sizeof(PyBytesObject)" with
1334 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1335 bytes instances. On a typical machine this saves 3 bytes of memory
1336 (on average) per allocation of a bytes instance.
1337
Christian Heimesa872de52008-12-05 08:26:55 +00001338- Issue #4533: File read operation was dreadfully slow due to a slowly
1339 growing read buffer. Fixed by using the same growth rate algorithm as
1340 Python 2.x.
1341
Antoine Pitrou5504e892008-12-06 21:27:53 +00001342- Issue #4509: Various issues surrounding resize of bytearray objects to
1343 which there are buffer exports (e.g. memoryview instances).
1344
Georg Brandlf9734072008-12-07 15:30:06 +00001345- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1346 method on file objects with closefd=False. The file descriptor is still
1347 kept open but the file object behaves like a closed file. The ``FileIO``
1348 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001349
Antoine Pitroubc420402008-12-07 20:14:49 +00001350- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1351 larger than 1.
1352
Benjamin Peterson371ccfb2008-12-27 19:03:36 +00001353- Issue #4748: Lambda generators no longer return a value.
1354
Gregory P. Smithccc5ae72009-03-02 05:21:55 +00001355- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
1356
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001357- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1358 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1359 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1360 of using the replace error handler in PyUnicode_DecodeUTF8().
