Antoine Pitrouf2c54842010-01-13 08:07:53 +000015- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
16 methods of bytes, bytearray and unicode objects by using a common
17 implementation based on stringlib's fast search. Patch by Florent Xicluna.
18
Mark Dickinson45b63652010-01-16 18:10:25 +000019- Issue #7632: Fix various str -> float conversion bugs present in 2.7
20 alpha 2, including: (1) a serious 'wrong output' bug that could
21 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
22 that occurred in debug builds when parsing certain long numeric
23 strings corresponding to subnormal values, and (3) a number of flaws
24 that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000025
Benjamin Petersonaea44282010-01-04 01:10:28 +000026- The __complex__ method is now looked up on the class of instances to make it
27 consistent with other special methods.
28

37 described in C99 Annex F.
38
Mark Dickinsoncbb62742009-12-27 15:09:50 +000039- Issue #1811: improve accuracy and cross-platform consistency for
40 true division of integers: the result of a/b is now correctly
41 rounded for ints a and b (at least on IEEE 754 platforms), and in
42 particular does not depend on the internal representation of an int.
43
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000044- Issue #6834: replace the implementation for the 'python' and 'pythonw'
45 executables on OSX.

678 leak-chasing test runs give sensible results. The previous method of

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000959
960Core and Builtins
961-----------------
962
Mark Dickinson865e01a2009-05-07 16:37:01 +0000963- Issue #5914: Add new C API function PyOS_string_to_double, and
964 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
965
Eric Smith741191f2009-05-06 13:08:15 +0000966- Issue #3382: float.__format__, complex.__format__, and %-formatting
967 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
968 affects nan -> NAN and inf -> INF.
969
Mark Hammond5a607a32009-05-06 08:04:54 +0000970- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
971 in all operations, including splitdrive, split, etc. splitunc() now issues
972 a PendingDeprecation warning.
973
Eric Smith63376222009-05-05 14:04:18 +0000974- Issue #5920: For float.__format__, change the behavior with the
975 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
976 to be like 'g' but with at least one decimal point and with a
977 default precision of 12. Previously, the behavior the same but with
978 a default precision of 6. This more closely matches str(), and
979 reduces surprises when adding alignment flags to the empty
980 presentation type. This also affects the new complex.__format__ in
981 the same way.
982
Martin v. Löwis011e8422009-05-05 04:43:17 +0000983- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
984
R. David Murrayb18500d2009-05-04 22:59:07 +0000985- Issue #5890: in subclasses of 'property' the __doc__ attribute was
986 shadowed by classtype's, even if it was None. property now
987 inserts the __doc__ into the subclass instance __dict__.
988
Antoine Pitrou244651a2009-05-04 18:56:13 +0000989- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
990 sequences. Patch by Nick Barnes and Victor Stinner.
991
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000992- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000993
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000994- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
995 received a new method, detach(). detach() disconnects the underlying stream
996 from the buffer or text IO and returns it.
997
Mark Dickinson33841c32009-05-01 15:37:04 +0000998- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
999 floats with absolute value over 1e50. Also remove length
1000 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1001 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001002
Eric Smith741191f2009-05-06 13:08:15 +00001003- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001004 format(complex(1, 2./3), '.5') now produces a sensible result.
1005
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001006- Issue #5864: Fix empty format code formatting for floats so that it
1007 never gives more than the requested number of significant digits.
1008
Eric Smith6dc46f52009-04-27 20:39:49 +00001009- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1010 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1011
Eric Smithcc32a112009-04-26 21:35:14 +00001012- Issue #5835: Deprecate PyOS_ascii_formatd.
1013
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001014- Issue #4971: Fix titlecase for characters that are their own
1015 titlecase, but not their own uppercase.
1016
Benjamin Peterson193152c2009-04-25 01:08:45 +00001017- Issue #5283: Setting __class__ in __del__ caused a segfault.
1018
Mark Dickinsonad476da2009-04-23 19:14:16 +00001019- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1020 z involves nans, infs or negative zeros.
1021
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001022- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001023
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001024- Issue #1869 (and many duplicates): make round(x, n) correctly
1025 rounded for a float x, by using the decimal <-> binary conversions
1026 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1027 consistently agrees with format(x, '.2f').
1028
Benjamin Petersonae937c02009-04-18 20:54:08 +00001029- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1030 some builtin types.
1031
Eric Smith0923d1d2009-04-16 20:16:10 +00001032- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1033
Eric Smith35e84722009-04-16 20:21:28 +00001034- Issue #5515: str.format() type 'n' combined with commas and leading
1035 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001036
1037- Implement PEP 378, Format Specifier for Thousands Separator, for
1038 floats.
1039
Mark Dickinson3370cce2009-04-17 22:40:53 +00001040- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001041 1e11, not 1e12. This avoids printing 13 significant digits in
1042 situations where only 12 of them are correct. Example problem
1043 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1044 long time.)
1045
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001046- Issue #1580: On most platforms, use a 'short' float repr: for a
1047 finite float x, repr(x) now outputs a string based on the shortest
1048 sequence of decimal digits that rounds to x. Previous behaviour was
1049 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001050 Another minor difference is that the new repr switches to
1051 exponential notation at 1e16 instead of the previous 1e17; this
1052 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001053
1054 There's a new sys attribute sys.float_repr_style, which takes
1055 the value 'short' to indicate that we're using short float repr,
1056 and 'legacy' if the short float repr isn't available for one
1057 reason or another.
1058
1059 The float repr change involves incorporating David Gay's 'perfect
1060 rounding' code into the Python core (it's in Python/dtoa.c). As a
1061 secondary consequence, all string-to-float and float-to-string
1062 conversions (including all float formatting operations) will be
1063 correctly rounded on these platforms.
1064
1065 See issue 1580 discussions for details of platforms for which
1066 this change does not apply.
1067
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001068- Issue #5759: float() didn't call __float__ on str subclasses.
1069
Georg Brandlabc38772009-04-12 15:51:51 +00001070- The string.maketrans() function is deprecated; there is a new static method
1071 maketrans() on the bytes and bytearray classes. This removes confusion about
1072 the types string.maketrans() is supposed to work with, and mirrors the
1073 methods available on the str class.
1074
R. David Murraydc6da8a2009-04-09 22:16:43 +00001075- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1076 its clarity and its speed.
1077
Matthias Klose091c7b12009-04-07 13:24:27 +00001078- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1079 to avoid compiler warnings.
1080
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001081- Issue #3739: The unicode-internal encoder now reports the number of characters
1082 consumed like any other encoder (instead of the number of bytes).

1220 byte, and the 'C' code only accepts a unicode character.
1221
Georg Brandl406b3d82009-04-11 21:24:37 +00001222- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1223 when hitting the recursion limit under certain circumstances.
1224
Brett Cannon0759dd62009-04-01 18:13:07 +00001225- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1226
Georg Brandlab6f2f62009-03-31 04:16:10 +00001227- Fix a segfault when running test_exceptions with coverage, caused by
1228 insufficient checks in accessors of Exception.__context__.
1229
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001230- Issue #5604: non-ASCII characters in module name passed to
1231 imp.find_module() were converted to UTF-8 while the path is
1232 converted to the default filesystem encoding, causing nonsense.
1233
Benjamin Peterson09832742009-03-26 17:15:46 +00001234- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001236- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1237 the end sys.path, for compatibility with the system install of Python.
1238
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001239- Issue #4688: Add a heuristic so that tuples and dicts containing only
1240 untrackable objects are not tracked by the garbage collector. This can
1241 reduce the size of collections and therefore the garbage collection overhead
1242 on long-running programs, depending on their particular use of datatypes.
1243
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001244- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
1245 improve its performance. Long divisions and remainder operations
1246 are now between 50% and 150% faster.
1247
Mark Dickinsonbd792642009-03-18 20:06:12 +00001248- Issue #4258: Make it possible to use base 2**30 instead of base
1249 2**15 for the internal representation of integers, for performance
1250 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1251 --enable-big-digits option to configure, which overrides the
1252 default. Add sys.int_info structseq to provide information about
1253 the internal format.
1254
Mark Dickinson081dfee2009-03-18 14:47:41 +00001255- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1256 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1257 and sizeof(Py_UNICODE) == 2.
1258
Eric Smith8ec90442009-03-14 12:29:34 +00001259- Issue #5237: Allow auto-numbered fields in str.format(). For
1260 example: '{} {}'.format(1, 2) == '1 2'.
1261
Antoine Pitrou652e7072009-03-13 19:25:20 +00001262- Issue #5392: when a very low recursion limit was set, the interpreter would
1263 abort with a fatal error after the recursion limit was hit twice.
1264
Matthias Klose042f1332009-04-04 14:32:42 +00001265- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1311
Lars Gustäbel42e00912009-03-22 20:34:29 +00001312- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1313 forever on incomplete input. That caused tarfile.open() to hang when used
1314 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Mark Dickinson87ec0852009-02-09 17:15:59 +00001365- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1366 it now forces its argument to double before testing for infinity.
1367
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001368- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1369 returns a non-number type.
1370

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001377
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001378- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001379 were suppressing all exceptions. These include list() and bytearray().
1380
Mark Dickinson1124e712009-01-28 21:25:58 +00001381- Issue #4707: round(x, n) now returns an integer if x is an integer.
1382 Previously it returned a float.
1383
Antoine Pitroub52ec782009-01-25 16:34:23 +00001384- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1385 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1386 evaluation loop is compiled with a new dispatch mechanism which gives
1387 speedups of up to 20%, depending on the system, on various benchmarks.
1388
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001389- Issue #4874: Most builtin decoders now reject unicode input.

1395
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001396- Issue #4838: When a module is deallocated, free the memory backing the
1397 optional module state data.
1398
Mark Dickinson8055afd2009-01-17 10:04:45 +00001399- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1400 type to (void *).
1401
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001402- Issue #4935: The overflow checking code in the expandtabs() method common
1403 to str, bytes and bytearray could be optimized away by the compiler, letting
1404 the interpreter segfault instead of raising an error.
1405
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001406- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1407 __next__ method.
1408
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001409- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1418 common cases are optimized thanks to a dedicated fast path and a moderate
1419 amount of loop unrolling.
1420
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001421- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1422 collecting the oldest generation) so that allocating lots of objects without
1423 destroying them does not show quadratic performance. Based on a proposal by
1424 Martin von Löwis at
1425 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1426
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001427- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001428 having been closed (for instance, a read() call could return some
1429 previously buffered data). Patch by Dmitry Vasiliev.
1430
Antoine Pitrou05608432009-01-09 18:53:14 +00001431- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1432 flag to work properly. Furthermore, when specifying -u, the text stdout
1433 and stderr streams have line-by-line buffering enabled (the default being
1434 to buffer arbitrary chunks of data).
1435
Raymond Hettinger35631532009-01-09 03:58:09 +00001436- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1437 instead of ints (reducing its size from 4 to 8 times thereby reducing
1438 Python's overall memory).
1439
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001440- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1441 an existing .py counterpart, override the co_filename attributes of all
1442 code objects if the original filename is obsolete (which can happen if the
1443 file has been renamed, moved, or if it is accessed through different paths).
1444 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1445
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001446- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1447 one byte. Also fixes the meaning of len() so that it returns the number of
1448 items, rather than the size in bytes.
1449
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001450- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1451
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001452- Issue #4747: When the terminal does not use utf-8, executing a script with
1453 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1454
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001455- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001456 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001457
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001458- Issue #3680: Reference cycles created through a dict, set or deque iterator
1459 did not get collected.
1460
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001461- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1462 where the tp_hash and tp_dict slots are both NULL.
1463
Georg Brandlccc47b62008-12-28 11:44:14 +00001464- Issue #4759: None is now allowed as the first argument of
1465 bytearray.translate(). It was always allowed for bytes.translate().
1466
Skip Montanaro80072cb2008-12-23 03:51:14 +00001467- Added test case to ensure attempts to read from a file opened for writing
1468 fail.

1474
Antoine Pitrou621601a2008-12-17 23:18:19 +00001475- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1476 print elapsed times, not only when some objects are uncollectable /
1477 unreachable. Original patch by Neil Schemenauer.
1478
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001479- Issue #3439: Add a bit_length method to int.
1480
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001481- Issue #2173: When getting device encoding, check that return value of
1482 nl_langinfo is not the empty string. This was causing silent build
1483 failures on OS X.
1484
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001485- Issue #4597: Fixed several opcodes that weren't always propagating
1486 exceptions.
1487
1488- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001489 context manager returns a value that cannot be converted to a bool.
1490
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001491- Issue #4445: Replace "sizeof(PyBytesObject)" with
1492 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1493 bytes instances. On a typical machine this saves 3 bytes of memory
1494 (on average) per allocation of a bytes instance.
1495
Christian Heimesa872de52008-12-05 08:26:55 +00001496- Issue #4533: File read operation was dreadfully slow due to a slowly
1497 growing read buffer. Fixed by using the same growth rate algorithm as
1498 Python 2.x.
1499
Antoine Pitrou5504e892008-12-06 21:27:53 +00001500- Issue #4509: Various issues surrounding resize of bytearray objects to

Antoine Pitrou88909542009-06-29 13:54:42 +00002120- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2121 regression tests in parallel, shortening the total runtime.
2122
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002123- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2124 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2125 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2126 skip the tests if DISPLAY is defined but can't be used.
2127
R. David Murraya21e4ca2009-03-31 23:16:50 +00002128- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002129 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002130 from test support, which does the conversion.
2131
Guilherme Polo9de29af2009-01-28 20:40:48 +00002132- Issue #5083: New 'gui' resource for regrtest.
