13-----------------
14
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000015- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
16 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
17
Benjamin Petersond12362a2009-12-30 19:44:54 +000018- Issue #7604: Deleting an unset slotted attribute did not raise an
19 AttributeError.
20

22 negative zero) in ** operator. The behaviour now conforms to that
23 described in C99 Annex F.
24
Mark Dickinsoncbb62742009-12-27 15:09:50 +000025- Issue #1811: improve accuracy and cross-platform consistency for
26 true division of integers: the result of a/b is now correctly
27 rounded for ints a and b (at least on IEEE 754 platforms), and in
28 particular does not depend on the internal representation of an int.
29
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000030- Issue #6834: replace the implementation for the 'python' and 'pythonw'
31 executables on OSX.
32
33 These executables now work properly with the arch(1) command:
34 ``arch -ppc python`` will start a universal binary version of python
35 in PPC mode (unlike previous releases).
36

53
Mark Dickinsond550c9a2009-11-15 09:57:26 +000054- Issue #7298: fixes for range and reversed(range(...)). Iteration
55 over range(a, b, c) incorrectly gave an empty iterator when a, b and
56 c fit in C long but the length of the range did not. Also fix
57 several cases where reversed(range(a, b, c)) gave wrong results, and
58 fix a refleak for reversed(range(a, b, c)) with large arguments.
59

169 should used for accessing the d_type and d_name members of structures
170 using PyDescr_COMMON.
171
172- Issue #6405: Remove duplicate type declarations in descrobject.h.

Benjamin Peterson05159c42009-12-03 03:01:27 +0000186- Issue #2422: When compiled with the ``--with-valgrind`` option, the
187 pymalloc allocator will be automatically disabled when running under
188 Valgrind. This gives improved memory leak detection when running
189 under Valgrind, while taking advantage of pymalloc at other times.

292
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000293- Issue #6816: runpy now provides a run_path function that allows Python code
294 to execute file paths that refer to source or compiled Python files as well
295 as zipfiles, directories and other valid sys.path entries that contain a
296 __main__.py file. This allows applications that run other Python scripts to
297 support the same flexibility as the CPython command line itself.
298
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000299- Issue #7318: multiprocessing now uses a timeout when it fails to establish

606 between concurrent executions on the same system.
607
Brett Cannon0ae45112009-11-05 01:17:22 +0000608- Issue #7248: In importlib.test.source.util a try/finally block did not make
609 sure that some referenced objects actually were created in the block before
610 calling methods on the object.
611
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000612- Issue #7222: Make thread "reaping" more reliable so that reference
613 leak-chasing test runs give sensible results. The previous method of
614 reaping threads could return successfully while some Thread objects were
615 still referenced. This also introduces a new private function:
616 :func:`_thread._count()`.
617
R. David Murray27144602009-10-19 15:26:16 +0000618- Issue #7151: fixed regrtest -j so that output to stderr from a test no
619 longer runs the risk of causing the worker thread to fail.
620
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000621- Issue #7055: test___all__ now greedily detects all modules which have an
622 __all__ attribute, rather than using a hardcoded and incomplete list.
623
R. David Murray0bc11ae2009-10-18 22:18:17 +0000624- Issue #7058: Added save/restore for things like sys.argv and cwd to
625 runtest_inner in regrtest, with warnings if the called test modifies them,
626 and a new section in the summary report at the end.

Mark Dickinson2e304402009-10-04 18:43:54 +0000628- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
629
Brett Cannon3c273842009-07-20 00:14:29 +0000630- Fixed tests in importlib.test.source.test_abc_loader that were masking
631 the proper exceptions that should be raised for missing or improper code
632 object bytecode.
633
Brett Cannonb49c70c2009-07-15 04:08:33 +0000634- Removed importlib's custom test discovery code and switched to
635 unittest.TestLoader.discover().

Mark Dickinson865e01a2009-05-07 16:37:01 +0000898- Issue #5914: Add new C API function PyOS_string_to_double, and
899 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
900
Eric Smith741191f2009-05-06 13:08:15 +0000901- Issue #3382: float.__format__, complex.__format__, and %-formatting
902 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
903 affects nan -> NAN and inf -> INF.
904
Mark Hammond5a607a32009-05-06 08:04:54 +0000905- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames

907 a PendingDeprecation warning.
908
Eric Smith63376222009-05-05 14:04:18 +0000909- Issue #5920: For float.__format__, change the behavior with the
910 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
911 to be like 'g' but with at least one decimal point and with a
912 default precision of 12. Previously, the behavior the same but with
913 a default precision of 6. This more closely matches str(), and
914 reduces surprises when adding alignment flags to the empty
915 presentation type. This also affects the new complex.__format__ in
916 the same way.

R. David Murrayb18500d2009-05-04 22:59:07 +0000920- Issue #5890: in subclasses of 'property' the __doc__ attribute was
921 shadowed by classtype's, even if it was None. property now

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000929- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
930 received a new method, detach(). detach() disconnects the underlying stream
931 from the buffer or text IO and returns it.
932
Mark Dickinson33841c32009-05-01 15:37:04 +0000933- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
934 floats with absolute value over 1e50. Also remove length
935 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
936 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +0000938- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000939 format(complex(1, 2./3), '.5') now produces a sensible result.
940
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000941- Issue #5864: Fix empty format code formatting for floats so that it
942 never gives more than the requested number of significant digits.
943
Eric Smith6dc46f52009-04-27 20:39:49 +0000944- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonc6300392009-04-20 21:38:00 +0000958
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000959- Issue #1869 (and many duplicates): make round(x, n) correctly
960 rounded for a float x, by using the decimal <-> binary conversions
961 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
962 consistently agrees with format(x, '.2f').
963
Benjamin Petersonae937c02009-04-18 20:54:08 +0000964- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
965 some builtin types.
966
Eric Smith0923d1d2009-04-16 20:16:10 +0000967- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
968
Eric Smith35e84722009-04-16 20:21:28 +0000969- Issue #5515: str.format() type 'n' combined with commas and leading
970 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000971
972- Implement PEP 378, Format Specifier for Thousands Separator, for
973 floats.
974
Mark Dickinson3370cce2009-04-17 22:40:53 +0000975- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000976 1e11, not 1e12. This avoids printing 13 significant digits in
977 situations where only 12 of them are correct. Example problem
978 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
979 long time.)
980
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000981- Issue #1580: On most platforms, use a 'short' float repr: for a
982 finite float x, repr(x) now outputs a string based on the shortest
983 sequence of decimal digits that rounds to x. Previous behaviour was
984 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000985 Another minor difference is that the new repr switches to
986 exponential notation at 1e16 instead of the previous 1e17; this
987 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000988
989 There's a new sys attribute sys.float_repr_style, which takes
990 the value 'short' to indicate that we're using short float repr,
991 and 'legacy' if the short float repr isn't available for one
992 reason or another.
993
994 The float repr change involves incorporating David Gay's 'perfect
995 rounding' code into the Python core (it's in Python/dtoa.c). As a
996 secondary consequence, all string-to-float and float-to-string
997 conversions (including all float formatting operations) will be
998 correctly rounded on these platforms.
999
1000 See issue 1580 discussions for details of platforms for which
1001 this change does not apply.
1002
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001003- Issue #5759: float() didn't call __float__ on str subclasses.
1004
Georg Brandlabc38772009-04-12 15:51:51 +00001005- The string.maketrans() function is deprecated; there is a new static method
1006 maketrans() on the bytes and bytearray classes. This removes confusion about
1007 the types string.maketrans() is supposed to work with, and mirrors the
1008 methods available on the str class.
1009
R. David Murraydc6da8a2009-04-09 22:16:43 +00001010- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1015
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001016- Issue #3739: The unicode-internal encoder now reports the number of characters

1173
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001174- Issue #4688: Add a heuristic so that tuples and dicts containing only
1175 untrackable objects are not tracked by the garbage collector. This can
1176 reduce the size of collections and therefore the garbage collection overhead
1177 on long-running programs, depending on their particular use of datatypes.

1298 rotating the object pointer by 4 bits to the right.
1299
Mark Dickinson87ec0852009-02-09 17:15:59 +00001300- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1301 it now forces its argument to double before testing for infinity.
1302
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001303- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001312
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001313- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001314 were suppressing all exceptions. These include list() and bytearray().
1315
Mark Dickinson1124e712009-01-28 21:25:58 +00001316- Issue #4707: round(x, n) now returns an integer if x is an integer.
1317 Previously it returned a float.
1318
Antoine Pitroub52ec782009-01-25 16:34:23 +00001319- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1320 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1321 evaluation loop is compiled with a new dispatch mechanism which gives
1322 speedups of up to 20%, depending on the system, on various benchmarks.
1323
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001324- Issue #4874: Most builtin decoders now reject unicode input.

1330
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001331- Issue #4838: When a module is deallocated, free the memory backing the
1332 optional module state data.
1333
Mark Dickinson8055afd2009-01-17 10:04:45 +00001334- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1335 type to (void *).
1336
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001337- Issue #4935: The overflow checking code in the expandtabs() method common
1338 to str, bytes and bytearray could be optimized away by the compiler, letting
1339 the interpreter segfault instead of raising an error.
1340
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001341- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1342 __next__ method.
1343
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001344- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1345 function no longer attempt to call the __long__ slot to convert an object
1346 to an integer. Only the __int__ and __trunc__ slots are examined.
1347
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001348- Issue #4893: Use NT threading on CE.
1349
Martin v. Löwisec59d042009-01-12 07:59:10 +00001350- Issue #4915: Port sysmodule to Windows CE.
1351
Antoine Pitrouab868312009-01-10 15:40:25 +00001352- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1353 common cases are optimized thanks to a dedicated fast path and a moderate
1354 amount of loop unrolling.
1355
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001356- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1357 collecting the oldest generation) so that allocating lots of objects without
1358 destroying them does not show quadratic performance. Based on a proposal by
1359 Martin von Löwis at
1360 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1361
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001362- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001363 having been closed (for instance, a read() call could return some
1364 previously buffered data). Patch by Dmitry Vasiliev.
1365
Antoine Pitrou05608432009-01-09 18:53:14 +00001366- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1367 flag to work properly. Furthermore, when specifying -u, the text stdout
1368 and stderr streams have line-by-line buffering enabled (the default being
1369 to buffer arbitrary chunks of data).
1370
Raymond Hettinger35631532009-01-09 03:58:09 +00001371- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1372 instead of ints (reducing its size from 4 to 8 times thereby reducing
1373 Python's overall memory).
1374
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001375- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1376 an existing .py counterpart, override the co_filename attributes of all
1377 code objects if the original filename is obsolete (which can happen if the
1378 file has been renamed, moved, or if it is accessed through different paths).
1379 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1380
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001381- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1382 one byte. Also fixes the meaning of len() so that it returns the number of
1383 items, rather than the size in bytes.
1384
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001385- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1386
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001387- Issue #4747: When the terminal does not use utf-8, executing a script with
1388 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1389
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001390- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001391 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001392
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001393- Issue #3680: Reference cycles created through a dict, set or deque iterator
1394 did not get collected.
1395
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001396- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1397 where the tp_hash and tp_dict slots are both NULL.
1398
Georg Brandlccc47b62008-12-28 11:44:14 +00001399- Issue #4759: None is now allowed as the first argument of
1400 bytearray.translate(). It was always allowed for bytes.translate().
1401
Skip Montanaro80072cb2008-12-23 03:51:14 +00001402- Added test case to ensure attempts to read from a file opened for writing
1403 fail.
1404
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001405- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00001407- Issue #2183: Simplify and optimize bytecode for list, dict and set
1408 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1409
Antoine Pitrou621601a2008-12-17 23:18:19 +00001410- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1411 print elapsed times, not only when some objects are uncollectable /
1412 unreachable. Original patch by Neil Schemenauer.
1413
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001414- Issue #3439: Add a bit_length method to int.
1415
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001416- Issue #2173: When getting device encoding, check that return value of
1417 nl_langinfo is not the empty string. This was causing silent build
1418 failures on OS X.
1419
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001420- Issue #4597: Fixed several opcodes that weren't always propagating
1421 exceptions.
1422
1423- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001424 context manager returns a value that cannot be converted to a bool.
1425
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001426- Issue #4445: Replace "sizeof(PyBytesObject)" with
1427 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1428 bytes instances. On a typical machine this saves 3 bytes of memory
1429 (on average) per allocation of a bytes instance.
1430
Christian Heimesa872de52008-12-05 08:26:55 +00001431- Issue #4533: File read operation was dreadfully slow due to a slowly
1432 growing read buffer. Fixed by using the same growth rate algorithm as
1433 Python 2.x.
1434
Antoine Pitrou5504e892008-12-06 21:27:53 +00001435- Issue #4509: Various issues surrounding resize of bytearray objects to
1436 which there are buffer exports (e.g. memoryview instances).
1437
Georg Brandlf9734072008-12-07 15:30:06 +00001438- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1439 method on file objects with closefd=False. The file descriptor is still
1440 kept open but the file object behaves like a closed file. The ``FileIO``
1441 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001442
Antoine Pitroubc420402008-12-07 20:14:49 +00001443- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1449
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001450- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1451 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1452 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1453 of using the replace error handler in PyUnicode_DecodeUTF8().
